Citation Nr: 0311183 Decision Date: 06/02/03 Archive Date: 08/07/03 DOCKET NO. 94-41 385 DATE JUN 02, 2003 On appeal from the Department of Veterans Affairs Regional Office in Portland, Oregon THE ISSUE Entitlement to service connection for a chronic pulmonary disability as residual to Agent Orange herbicide exposure or to asbestos exposure. REPRESENTATION Appellant represented by: Disabled American Veterans WITNESS AT HEARINGS ON APPEAL Appellant ATTORNEY FOR THE BOARD Frank L. Christian, Counsel INTRODUCTION The veteran served on active duty in the United States Navy from June 1965 to June 1967, including service in the offshore waters of the Republic of Vietnam. This matter comes before the Board of Veterans' Appeals (Board) on appeal from a rating decision of October 1993 from the Department of Veterans Affairs (VA) Regional Office (RO) in Montgomery, Alabama, which determined that new and material evidence has not been submitted to reopen the claim for service connection for a chronic pulmonary disability as residual to Agent Orange (AO) herbicide exposure or asbestos exposure since the last final denial of that claim by rating decision of December 1981. This claim was previously before the Board in July 2001, at which time it was determined that new and material evidence has been submitted to reopen the claim for service connection for a chronic pulmonary disability as residual to AO herbicide exposure or asbestos exposure. The case was remanded for additional notification and assistance to the claimant in compliance with the Veterans Claims Assistance Act of 2000 (VCAA), to include obtaining all pertinent private and VA treatment records of the claimant not already associated with the claims folder; to solicit any further information as to dates, times, places, witnesses, or other data that would assist in corroborating the claimant's account of being exposed to asbestos or herbicides; and to afford the claimant a VA pulmonary examination by a qualified examiner who has reviewed his claims folder to ascertain whether the appellant's lung disorder was caused by in-service exposure to asbestos or herbicides. The requested actions have been satisfactorily completed and the case has been returned to the Board for further appellate consideration. There has been a significant change in the law with the enactment of the Veterans Claims Assistance Act of 2000, Pub. L. No. 106-475, 3(a), 114 Stat. 2096, 2097- 98 (2000) [codified as amended at 38 U.S.C.A. 5102, 5103, 5103A, and 5107 - 2 - (West 2000)]. This law eliminates the concept of a well-grounded claim, redefines the obligations of VA with respect to the duty to assist, and supersedes the decision of the United States Court of Appeals for Veterans Claims (the Court) in Morton v. West, 12 Vet. App. 477 (1999), withdrawn sub nom. Morton v. Gober, No. 96-1517 (U.S. Vet. App. Nov. 6, 2000) (per curiam order) (holding that VA cannot assist in the development of a claim that is not well grounded). The VCAA is applicable to all claims filed on or after the date of enactment, November 9, 2000, or filed before the date of enactment and not yet final as of that date. See Karnas v. Derwinski, 1 Vet. App. 308, 312-13 (1991). In Karnas v. Derwinski, 1 Vet. App. 308, 312-13 (1991), the Court held that where a statute or regulation changes during the appellate process, the version more favorable to the claimant shall apply. VA's General Counsel has determined, in a precedential opinion that the Board is bound to follow, that the VCAA is more favorable to claimants than the law in effect prior to its enactment. See VAOPGCPREC 11-00; Janssen v. Principi, 15 Vet. App. 123 (2001) (per curiam). Final regulations to effectuate the VCAA were published on August 29, 2001 with the same effective date of the VCAA, November 9, 2000. Except for the amendment to 38 CFR 3.156(a), the second sentence of 38 CFR 3.159(c), and 38 CFR 3.159(c)(4)(m), effective August 29, 2001, governing reopening of previously and finally denied claims, the provisions of this final rule apply to any claim for benefits received by VA on or after November 9, 2000, as well as to any claim filed before that date but not decided by VA as of that date. As the instant appeal does not address a reopened claim, the revised regulations pertaining to reopened claims are inapplicable to this matter. The record shows that the claimant and his representative were notified of the provisions of the VCAA by RO letter of January 28, 2002, which informed them of VA's duty to notify them of the information and evidence necessary to substantiate the claim and to assist them in obtaining all such evidence. That letter also informed the claimant and his representative which part of that evidence would be obtained by the RO and which part of that evidence would be obtained by the - 3 - claimant, pursuant to Quartuccio v. Principi, 16 Vet. App. 183, 187 (2002) (requiring VA to notify the claimant of what evidence he or she was required to provide and what evidence the VA would attempt to obtain). The claimant and his representative were also provided a Supplemental Statement of the Case on January 30, 2003, which informed them of the issue on appeal, the evidence considered, the adjudicative actions taken, the pertinent law and regulations pertaining to service connection generally and to service- connection based upon herbicide exposure, the decision reached, and the reasons and bases for that decision. The Board finds that all relevant evidence necessary for an equitable disposition of the instant appeal has been obtained by the RO, and that VA's duty of notification to the claimant and his representative of required information and evidence and of its duty to assist them in obtaining all evidence necessary to substantiate the issue on appeal have been fully met. The RO has obtained the claimant's complete service medical and personnel records, as well as all private or VA medical evidence identified by the claimant. The RO has further afforded the claimant a personal hearing before an RO Decision Review Officer in March 1999, and a hearing in May 2001 before the undersigned traveling Veterans Law Judge of the Board of Veterans' Appeals. Neither the appellant nor his representative have argued a notice or duty to assist violation under the VCAA, and the Board finds that it is clear that the appellant and his representative were fully notified and aware of the type of evidence required to substantiate the claim. In view of the extensive factual development in the case, as demonstrated by the Board's July 2001 remand order and the record on appeal, the Board finds that there is no reasonable possibility that further assistance would aid in substantiating this appeal. For those reasons, further development is not necessary for compliance with the provisions of 38 U.S.C.A. 5103 and 5103A (West 2000). - 4 - FINDINGS OF FACT 1. All relevant evidence necessary for an equitable disposition of the instant appeal has been obtained by the RO, and VA's duty of notification to the claimant of required information and evidence and of its duty to assist him in obtaining all evidence necessary to substantiate his claim have been fully met. 2. The claimant's service medical records are silent for complaint, treatment, findings or diagnosis of a chronic pulmonary disability during active service, on service separation examination, within any applicable presumptive period, or at any time prior to October 1978, more that 11 years after final service separation. 3. The claimant does not have a chronic lung disease which is presumptively related to AO herbicide exposure, and does not have asbestosis or an asbestosis- related pleural disease. 4. Competent medical evidence and opinion has related the claimant's current COPD to his 70-pack-year smoking history. CONCLUSION OF LAW A chronic pulmonary disability was not incurred in or aggravated by active service, and was not caused or worsened by AO herbicide exposure or by asbestos exposure. 38 U.S.C.A. 1110, 1116(a), 5013, 5013A (West 2000); 38 C.F.R. 3.102, 3.303(a), 3.303(e), 3.307(a)(6), 3.309(a)(d), 3.313(a) (2002). 5 - REASONS AND BASES FOR FINDINGS AND CONCLUSION I. The Evidence In view of the determination that new and material evidence has been submitted to reopen the claim for service connection for a chronic pulmonary disability (COPD), claimed as residual to AO herbicide exposure or asbestos exposure while on active duty, the Board will address the claim on a de novo basis, including consideration of all the evidence, both old and new. As noted, the claimant served on active duty in the United States Navy from June 1965 to June 1967. A report of service entrance examination, conducted in June 1965, showed that his lungs and chest were normal. His service medical records are silent for complaint, treatment, findings, or diagnosis of a lung or pulmonary disorder during his period of active service or on service separation examination. A report of chest X-ray in November 1966 disclosed that his chest was normal. The claimant's report of service separation examination, conducted in June 1967, showed that his lungs and chest were normal, and a chest X-ray was negative for any abnormalities. The claimant's service personnel records show that he was stationed aboard USS O'BRIEN (DD 725) during his entire period of active duty. In June 1966, he was awarded the National Defense Medal, and was awarded the Vietnam Service Medal (VCM) for duty in waters contiguous of Vietnam. Those records further establish that the claimant served in the offshore waters of the Republic of Vietnam, from November 18 through 24, 1965; from January 16 through February 2, 1966; from December 20 through 24, 1966; from January 9 through January 24, 1967; from March 31 through April 17, 1967; and from June 24 through July 7, 1967. An October 1970 report of medical history completed by the claimant in connection with his reenlistment in the Naval Reserve denied any history of shortness of breath, asthma, chronic cough, or chest pain or pressure in the chest. A report of medical - 6 - examination for reenlistment in the Naval Reserve, conducted in October 1970, showed that his lungs and chest were normal, and a chest X-ray was negative. The claimant's original application for VA disability compensation benefits (VA Form 21-526), received in October 1978, made no mention of a pulmonary or lung disorder. Private treatment records from the Columbia Memorial Hospital, a private medical facility in Astoria, Oregon, show that the claimant was seen in the Emergency Room on October 6, 1978, with an acute episode of shortness of breath, and no breath sounds in the right lung. X-rays revealed a well-defined right-sided pneumothorax, with approximately 75% collapse of the lung, and bullous emphysema was present at the apex. Following insertion of a chest tube, his respiratory distress immediately improved. The claimant related that he had a history of 3 automobile accidents, the most recent in 1970, when he sustained multiple contusions of the right ribs and multiple lacerations. He was admitted with a diagnosis of spontaneous pneumothorax. Further X-rays revealed pneumonic infiltrates in the right perihilar area and right base, with bilateral bullous emphysema at the apices. The claimant was subsequently transferred to the VAMC, Vancouver, on October 13, 1878. On October 13, 1978, the appellant was hospitalized at a VA facility and underwent right and left thoracotomies with pleurodeses. It was noted that the appellant had been admitted to a private medical facility after sustaining a right-sided spontaneous pneumothorax with emphysematous blebs in both lungs; that the appellant was then smoking between two and three packs of cigarettes daily; and that he was advised to discontinue smoking permanently; otherwise he would have a destroyed lung, which was not reversible. The claimant underwent a bilateral blebectomy, without complications, and postoperative treatment records showed that the claimant's lungs were clear, without rales, and a chest X- ray was described as looking good, with no evidence of pneumothorax. The treating physician noted that the appellant was continuing to smoke when discharged from the hospital in November 1978. - 7 - VA outpatient treatment records, dated from February to October 1979, show that in February 1979, the claimant was doing well and working full time, while in March 1979, he was seen complaining of a cold and coughing for the past four weeks, diagnosed as a resolving upper respiratory infection with emphysema. A chest X- ray in June 1979 disclosed no change from previous films taken in December 1978. In October 1979, the claimant was seen for complaints of pain in the upper right chest, worse on deep breathing, and a non-productive cough. It was noted that emphysematous blebs were diagnosed in October 1978, while current examination revealed that his throat was clear, without rales, and a chest X-ray was negative. In a statement received in December 1979, the appellant alleged he had a bilateral lung condition caused by in-service exposure to asbestos. He stated that his symptoms of coughing began during such service. A January 1980 report from a private physician, Dr. G.H., shows that the claimant underwent surgery in November 1978 after his lungs collapsed; that he currently had a 64% loss of lung function; and that he was very weak because of his lung trouble. A report of VA examination, conducted in February 1980, cited the claimant's assertion that he was exposed to asbestos for two years while in the Navy; that he started smoking 1 to 1 1/2 packs of cigarettes daily in 1964, and currently smoked a half-pack daily; that he has had a chronic cough since 1965; that in October 1978, he was admitted to the VAMC, Vancouver, with a spontaneous right- sided pneumothorax, and underwent a removal of blebs during that hospitalization. He related that he was a long-haul truck driver in the past, but was not able to work around dust or diesel fumes. Examination disclosed well-healed, nontender, 6" thoracotomy scars in both axilla. The pertinent diagnoses were COPD (mild by pulmonary function tests (PFT's)), with spontaneous pneumothorax, right side; bilateral emphysematous blebs; and status post bilateral thoracotomies with pleurodesis for the blebs. 8 - In a March 1980 statement, Dr. E.L.M., a VA physician, reported that the appellant's recent PFT's tests demonstrated moderately severe obstructive emphysema, and that radiographic examination detected residuals of old fibrosis or pleural reaction in both of the upper thoraces. A rating decision of April 1980 denied service connection for a lung disability as residual to asbestos exposure. The claimant was notified of that adverse determination and of his right to appeal by RO letter of May 13, 1980, but did not initiate an appeal and that decision became final. In August 1981, the claimant submitted an application for VA disability compensation or pension benefits for bilateral lung disabilities, alleging that he was exposed to AO herbicide while in Vietnam aboard ship, and that he was breathing asbestos dust all the time while aboard ship. In September 1981, the appellant submitted a VA Herbicide Exposure questionnaire. In part, he reported that on several occasions while serving off of the coast of Vietnam, he was exposed to the herbicide "Agent Orange" during "Operation Ranch Hand." During a further VA medical examination in November 1981, the appellant reiterated that he had been exposed to asbestos and herbicides while serving on active naval duty. As to the former, he reported that asbestos powder could be seen coming from the ship's insulation when guns were fired, and that the vessel's steam pipes were all insulated with the material. He also claimed that his vessel came close to the shoreline where herbicides were being used between 1965 to 1967, and that dispersing aircraft flew overhead frequently. It was noted that the appellant was still smoking about a quarter of a pack of cigarettes per day. Pulmonary function tests revealed that overall ventilatory function was normal, while there was severe obstruction to expired air flow in small airways. The pertinent diagnoses were COPD, with history of spontaneous pneumothorax, right side; bilateral emphysematous blebs; and status post bilateral thoracotomies with pleurodesis, bilaterally. 9 - A rating decision of April 1980 denied service connection for a lung disability as residual to Agent Orange (AO) herbicide exposure. The claimant and his representative were notified of that adverse determination and of his right to appeal by RO letter of December 13, 1981, but did not initiate and appeal and that decision became final. A VA hospital summary, dated in February 1982, shows that the claimant was admitted for symptoms unrelated to the current claim. That summary shows that the claimant had severe emphysema, shortness of breath, and a cough, with a history of previous surgery for emphysematous blebs, but continues to smoke a quarter- pack of cigarettes daily. The appellant sought to reopen his claim by application received in June 1993. A report of VA pulmonary examination in September 1993, cited a history of asbestos and herbicide exposure as recounted by the claimant, and it was noted that the appellant was then smoking a half of a pack of cigarettes per day. He reported that he served aboard ship, acting as a coastal patrolman, about 100-150 feet off the beaches of Vietnam, and was exposed to AO herbicide. The claimant reported that after service, he was doing fine and working full-time as a long haul truckdriver, when he experienced an acute shortness of breath, and was hospitalized for pneumothorax. He returned to employment as a truckdriver in early 1979 and continued until 1984, quitting because of long hours and stress. He related that he worked in auto repair from 1984 to 1986, operated a tavern from 1986 to 1988, and took a full-time job at the Cascade General Shipyard as a sand blaster and painter, where he remained currently employed. Pulmonary function tests revealed a mild overall ventilatory impairment, with a moderate obstructive component, and chest X-ray revealed emphysema. The appellant was diagnosed with emphysema, and it was noted that he had very early onset of severe bulbous emphysema. Although the appellant reported being exposed to "Agent Orange," it was noted that he then showed no evidence of chloracne or neoplasms. A rating decision of October 1993 determined that new and material evidence had not been submitted to reopen the claim for service- connection for a lung condition 10- as residual to asbestos exposure. The claimant and his representative were notified of that adverse determination and of his right to appeal by RO letter of October 29, 1993. In a statement received in February 1994, the appellant claimed that when on active naval service, he was told by a ship's physician that he had been exposed to "Agent orange." He added that he had stood on the decks of U.S.S. O'BRIEN as helicopters flew over the ship to spray the waters with the substance in an effort to kill fish and diminish the enemy's food supply. In his substantive appeal, the ,appellant claimed that at the time of his October 1978 thoracotomies, he was informed by two physicians that he had "Agent Orange in [his] system." That Document was accepted as a Notice of Disagreement, and a Statement of the Case was provided the claimant and his representative in August 1994. In his Substantive Appeal (VA Form 9), received in October 1994, the claimant alleged that he had lost 2/3's of his lung capacity due to AO herbicide and asbestos exposure. He requested a personal hearing before an RO Hearing Officer and a hearing before a traveling Veterans Law Judge of the Board of Veterans' Appeals. A report of VA medical examination in November 1994 cited the claimant's statement that he continued to smoke from one-quarter to one-half of a pack of cigarettes per day, and a smoking history of at least 40-pack-years. The appellant reported that he had been exposed to asbestos while in service. In part, the diagnoses showed, in pertinent part, that the claimant had chronic obstructive pulmonary disease, with evidence of a severe small airways disease on pulmonary function tests. A report of private medical examination for the Social Security Administration (SSA), conducted in October 1995, shows that the claimant was alert and slightly obese; and that his former occupations were sand blaster and painter. He complained of some shortness of breath, which he related to AO herbicide exposure, and indicated that he smoked one-quarter to one-half packs of cigarettes daily, down from two packs daily. The assessment was emphysema and fibrosis of the lungs. In a statement received in October 1996, the appellant stated that one of the VA physicians who treated him in October 1978 and informed him that he had "Agent Orange" in his system, was Dr. E.M., who had performed his surgery. A rating decision of January 1997 denied service connection for a lung disability as residual to herbicide exposure. The claimant and his representative were notified of that adverse determination and of his right to appeal by RO letter of February 5, 1997. The appellant underwent a VA respiratory examination in March 1998. The examiner reported that the appellant's VA claims folder had been reviewed. However, he further observed that the appellant had: " ... a history of spontaneous pneumothoraxes bilaterally in 1978. He had bilateral chest tubes, and in fact it sounds like he had a thoracotomy. Medical records from that period of time are not available, so I cannot elaborate further on the procedures that were done at that time." The examiner observed that the appellant had reported a history of asbestos exposure while on ships during service in the 1960's, and that subsequent to service, the appellant worked as an automotive mechanic, a construction worker, and in shipyards. The examiner also noted that the appellant had some degree of obesity (283 pounds); that he had a 50-60-pack-year history of smoking; and that he was then smoking approximately one pack of cigarettes per day. The VA pulmonary examiner diagnosed chronic obstructive pulmonary disease, recommending further chest X-rays and pulmonary function tests(PFT's), and stated that if the PFT's indicate restrictive disease, part of that would be due to the obesity, although restrictive airway disease can be a result of asbestosis as well, so that would be a probable contributing factor. He further noted that if the chest X-ray showed plaques, such would be indicative of asbestos. He expressed the opinion that the majority of the claimant's breathing problem was from obstructive - 12 - pulmonary disease which was not from asbestos but was highly probably the result of his smoking history, while stating that if the PFT's showed restrictive disease, it would be his opinion that it was at least worsened by exposure to asbestos. Current PFT's disclosed moderate ventilatory impairment, with a severe obstructive component, reversible with bronchodilators. There were no findings of restrictive disease. A chest X-ray disclosed that the claimant's lungs were hyperaerated, with apparent bullae in the right pulmonary apex; a fine, linear pattern of opacity, diffusely, which was most likely related to scarring, with multiple areas of pleural thickening in the upper and mid- thoracic wall region, bilaterally, while the pulmonary hilar contours were within normal limits, and there was no evidence of consolidation or parenchymal nodular densities or pleural calcifications. The radiographic impression was hyperaeration and probable pulmonary fibrosis, findings which are compatible and consistent with the proffered history of asbestos exposure, and bilateral, prominent pleural plaques compatible with asbestos- related disease. VA outpatient treatment records, dated in June 1998, showed that the claimant had a history of pneumothorax, with bilateral thoracotomy and pleurodesis, which the claimant related to AO herbicide exposure. It was noted that his chart also showed a diagnosis of COPD/ reactive airway disease, and that the claimant continued to smoke. Medical records obtained from the Social Security Administration (SSA) show, in pertinent part, that the claimant was seen in the emergency room of Columbia Memorial Hospital in October 1978 with an acute episode of shortness of breath. A surgical report, written by Dr. T.A.P., noted that the appellant's past medical history was "essentially unremarkable," and that he had been involved in 3 automobile accidents - the last occurring about eight years previously and causing the appellant to have multiple contusions of the right ribs. A personal hearing was held at the RO in March 1999 before an RO Decision Review Officer. In substance, the claimant reiterated his prior accounts of having - 13 - been exposed to herbicides and asbestos during active naval service. A transcript of the testimony is of record. In January 2000, a statement was received from a Navy Liaison office. The agency reported that it was unable to determine to what extent the appellant was exposed to asbestos during his service. It added that while general specifications for ships required that heated surfaces be covered with insulation at the time of the appellant's service, and it was "highly probable" that asbestos products were used, the probability to the appellant being exposed to asbestos as a seaman was minimal. In a February 2000 letter to the RO, the claimant asserted that he was exposed to AO herbicide while on active duty; and that he was told by service physicians at the time of service separation that he should think seriously before having children because the long term effects of AO herbicide were unknown; A December 2000 letter from Dr. L.L.A., a physician at the VAMC, Portland, stated that the claimant was a patient in her Internal Medicine practice at the VAMC; that he had a history of asbestos exposure, with finding of multiple areas of pleural thickenings on his chest x-rays. In February 2001, the claimant appointed Disabled American Veterans (DAV) as his accredited service organization representative, revoking all previous appointments. In April 2001, the claimant submitted an application for a total disability rating based upon unemployability due to service- connected disabilities (VA Form 21-8940). He reported that he was employed as a sand blaster and painter from March 1989 to September 1993. In May 2001, the appellant testified before the undersigned traveling Veterans Law Judge of the Board of Veterans' Appeals, and reiterated his prior contentions regarding exposure to AO herbicide and asbestos while on active duty. A transcript of the testimony is of record. - 14 - Following the Board's July 2001 determination that new and material evidence had been submitted to reopen the claim for service connection for a chronic pulmonary disability as residual to AO herbicide exposure or asbestos exposure, the case was remanded for additional notification and assistance to the claimant in compliance with the Veterans Claims Assistance Act of 2000 (VCAA), and for additional development of the evidence, as more fully described previously in that remand order. In an Asbestos Exposure Questionnaire, completed by the claimant in February 2002, he asserted that he was exposed to asbestos while a Torpedoman and Bosun's Mate serving aboard USS O'BRIEN (DD 725) in 1965, 1966, and 1967; and that he was exposed to AO herbicide while serving aboard USS O'BRIEN (DD 725) in 1965, 1966, and 1967. An Employer's Statement (VA Form 21-4192), received in June 2002, related that the claimant was laid off on September 23, 1993. A Ship's History of USS O'BRIEN (DD 725), received in December 2002, showed that O'BRIEN was attached to the 7th Fleet in August 1965, and was ordered to patrol the Taiwan Straits; that in November 1965, O'BRIEN provided gunfire support to a surrounded outpost in Quang Ngai province; that in January and early February 1966, O'BRIEN supported carrier operations, conducted search and rescue missions in the Tonkin Gulf, and provided gunfire support for amphibious landing near Cape Batangan, Operation "Double Eagle"; that after November 1966, O'BRIEN became flagship for Operation "Sea Dragon", a surface action task unit off North Vietnam, where she was ordered to interdict enemy coastal traffic, and receiving fire from enemy coastal batteries north of Dong Hoi in December 1966; that in January 1967 and subsequently, O'Brien provided support for air strikes from carriers in the Tonkin Gulf, returning to patrol duty in the Taiwan Strait in February and March 1967. In late March 1967, O'Brien returned to the Tonkin Gulf as a carrier escort and subsequently participated in "Sea Dragon" operations, - 15 - where she served as flagship for the Commander, Destroyer Division 232, until returning to Long Beach in May 1967. A report of VA pulmonary examination, conducted in October 2002, cited the claimant's assertion that he was exposed to asbestos while serving aboard a United States Navy ship from 1965 to 1967; that the bulkhead compartments and work areas were lined with asbestos; that the claimant had bilateral thoracotomies for pneumothoraxes, with a right pleurodesis; that the claimant continues to smoke a half-pack per day, down from two packs a day; that he has a 70-pack-year smoking history, and has been diagnosed with COPD, treated with theophylline, Atrovent, and albuterol and steroid inhalers. The examiner stated that he was not able to discern evidence in the medical records of calcified plaques, or any clear evidence of asbestosis. Examination disclosed that the claimant was obese, weighing 256 pounds, but was currently breathing comfortably, with no wheezing, no intercostal retractions, and no accessory muscle use. His lungs were clear, with a somewhat poor excursion, while marked clubbing of the fingers of both hands was noted, without cyanosis or edema. The examination was otherwise unremarkable. The diagnoses were severe COPD with previous PFT findings in 1998 showing severe obstructive disease, which the examiner stated was probably the main cause of his respiratory symptoms, while his obesity was likely a contributing cause; and no clear evidence of asbestosis or asbestos-related pleural disease, with no findings of calcified pleural plaques. Current chest X-rays revealed left costophrenic angle discoid atelectasis versus scarring, with no active disease in the chest, and no evidence of calcified pleural plaques or evidence of asbestosis in the claimant, while current PFT's disclosed severe obstructive ventilatory disease. The claimant underwent another VA pulmonary examination in January 2003, following the examiner's review of the claims file. The examiner called attention to 44 exhaustive findings in the claims file of emphysema and COPD", without "any diagnostic test results indicating asbestosis or asbestos-related pleural disease" in the claimant. He noted records confirming pneumothoraces in 1978, at which time the claimant was a heavy smoker of two or three packs daily, with findings of pneumothorax secondary to emphysematous blebs. He further cited clinical - 16 - evidence in June 1995 that the claimant was being treated with theophylline, Amzacort, and albuterol for his COPD, while in October 1995, he was shown on PFT's to have severe obstructive disease and it was noted that his civilian occupation had been sandblaster and painter. The VA pulmonary examiner noted that, while it was probable that the claimant did have a considerable amount of asbestos exposure, there was no evidence in the record of test results establishing the presence of asbestosis or asbestos-related pleural disease in the claimant. The examiner expressed the opinion that in the absence of any objective tests showing asbestosis or asbestos- related pleural disease in the claimant, together with his documented 70+-pack-year smoking history with severe COPD documented for many years, there was less than 50 percent probability that there was any significant contribution to his respiratory symptoms from the asbestos exposure that he had in the past. He further indicated that the claimant's obesity might have had some contribution to the claimant's respiratory symptoms to which the claimant's COPD was the major contributing factor, so that his obesity might contribute somewhat to his respiratory symptoms but not to his COPD. He further clarified that the claimant's COPD was more probably than not the primary cause of his respiratory symptoms. In addition, the VA pulmonary examiner stated that AO herbicide exposure has not been established as a cause of COPD, and that in his opinion, there was less than a 50 percent probability that AO herbicide exposure is a cause of the claimant's COPD. VA outpatient treatment records from the VAMC, Portland, Vancouver and Portland Divisions, dated from January 2000 to January 2003, show that the claimant continued to obtain medication and inhalers for his COPD. II. Analysis in order to establish service connection for claimed disability, the facts, as shown by evidence, must demonstrate that a particular disease or injury resulting in current disability was incurred during active service or, if preexisting active service, was aggravated therein. 38 U.S.C.A. 1110, 1131 (West 2000); 38 C.F.R. 3.3 03(a) - 17 - (2002). Service connection may also be granted on a presumptive basis for certain chronic disabilities, including bronchiectasis, when manifested to a compensable degree within the initial post service year. 38 C.F.R. 3.307, 3.309(a) (2002). A veteran who served during a period of war or during peacetime service after December 31, 1946, is presumed in sound condition except for defects noted when examined and accepted for service. 38 U.S.C.A. 1111, 1137 (West 2000). Clear and unmistakable evidence that the disability existed prior to service will rebut this presumption. 38 U.S.C.A. 1111 (West 2000); 38 C.F.R. 3.304(b) (2002). In addition, if a condition noted during service is not shown to be chronic, then continuity of symptomatology after service generally is required for service connection. 38 C.F.R. 3.303(b) (2002). The chronicity provision of 38 C.F.R. 3.303(b) is applicable where evidence, regardless of its date, shows that a veteran had a chronic condition in service or during an applicable presumption period and still has such condition. Such evidence must be medical unless it relates to a condition as to which, under the court's case law, lay observation is competent. If the chronicity provision is not applicable, a claim may still be established or reopened on the basis of 38 C.F.R. 3.303(b) if the condition is observed during service or any applicable presumption period, continuity of symptomatology is demonstrated thereafter, and competent evidence relates the present condition to that symptomatology. Savage v. Gober, 10 Vet. App. 488 (1997). As a general matter, reliance upon the records of the service department is now well settled. See Soria v. Brown, 118 F.3d 747, 749 (Fed. Cir. 1997); Spencer v, West, 13 Vet. App. 376, 380 (2000); Venturella v. Gober, 11 Vet. App. 340, 341 (1997); Cahall v. Brown, 7 Vet. App. 232, 237 (1994). In this matter, there is no reason to question the appellant's service medical and personnel records as to their accuracy. Sarmienti v. Brown, 7 Vet. App. 80, 82-83 (1994). These records appear complete on their face, and disclose no complaint, treatment, findings or diagnosis of a chronic pulmonary right ankle trauma or pathology during active service. - 18 - A disability which is proximately due to or the result of a service-connected disease or injury shall be service connected. When service connection is thus established for a secondary condition, the secondary condition shall be considered a part of the original condition. 38 U.S.C.A. 1110, 1131 (West 2000); 38 C.F.R. 3.310(a) (2002); Harder v. Brown, 5 Vet. App. 183, 187 (1993). The United States Court of Veterans' Appeals (Court) has held, in pertinent part, that the term "disability" as used in 38 U.S.C.A. 1110 (West 2000) refers to impairment of earning capacity, and that such definition mandates that any additional impairment resulting from an already service-connected condition, regardless of whether or not the additional impairment is itself a separate disease or injury caused by the service-connected condition, shall be compensated (emphasis in original). Thus, pursuant to 38 U.S.C.A. 1110 and 38 C.F.R. 3.310(a) (2002), when aggravation of a veteran's nonservice-connected condition is proximately due to or the result of a service-connected condition, such veteran shall be compensated for the degree (but only that degree) over and above the degree of disability existing prior to the aggravation. Allen v. Brown, 7 Vet. App. 439,448 (1995). Evidence of the veteran's current condition is not generally relevant to the issue of service connection, absent some competent linkage to military service. See, e.g., Morton v. Principi, 3 Vet. App. 508, 509 (1992); Mingo v. Derwinski, 2 Vet. App. 51, 53 (1992). The Court has held that a lay person, such as the claimant, is not competent to offer evidence that requires medical knowledge, such as the diagnosis or cause of a disability. See Ramey v. Brown, 9 Vet. App. 40 (1996); Cromley v. Brown, 7 Vet. App. 376, 379 (1995); Holland v. Brown, 6 Vet. App. 443 (1994); Grottveit v. Brown, 5 Vet. App. 91, 93 (1993); Espiritu v. Derwinski, 2 Vet. App. 492, 495 (1992). If such evidence is not competent, it cannot be probative. As causative factors of a disease amount to a medical question; only a physician's opinion would be competent evidence. Gowen v. Derwinski, 3 Vet. App. 286, 288 (1992). A claimant's statements as to nexus are entitled to no probative weight. Layno v. - 19 - Brown, 6 Vet. App. 465 (1994). The Court has held, however, that a veteran's statements are competent as to the onset and continuity of symptomatology, including pain. Heuer v. Brown, 7 Vet. App. 379, 384 (1995); Falzone v. Brown, 8 Vet. App. 398, 405 (1995). A service connection claim must be accompanied by evidence which establishes that the claimant currently has the claimed disability. See Caluza v. Brown, 7 Vet. App. 498 (1995), affirmed per curiam, 78 F.3d 604 (Fed. Cir. 1996); Brammer v. Derwinski, 3 Vet. App. 223, 225 (1992); Rabideau v. Derwinski, 2 Vet. App. 141, 144 (1992). In the instant appeal, the medical evidence includes no clinical or radiographic findings or competent diagnosis showing asbestosis or asbestosis- related pleural disease in the claimant, and he does not meet the minimum requirements for an allowance of service connection for such disability on a direct or secondary basis in the absence of such diagnosis. See, e.g., Degmetich v. Brown, 104 F.3d 1328 (Fed. Cir. 1997); Gilpin v. Brown, 155 F.3d 1353 (Fed. Cir. 1998) [service connection may not be granted unless the claimed disability currently exists]. Under the statutory and case law, it is clear that a fundamental element of a claim for service connection is competent evidence of "current disability." See Rabideau and Brammer, supra. A "current disability" means a disability shown by competent medical evidence to exist at the time of the award of service connection. See Degmetich, supra. As the Court has held, the regulatory definition of "disability" is the "...impairment of earning capacity resulting from such diseases or injuries and their residual conditions...." 38 C.F.R. Part 4, 4.1 (2002); Hunt v. Derwinski, 1 Vet. App. 292, 296 (1991). No such disability involving the claimant's pulmonary system and attributable to herbicide or asbestos exposure has been medically identified or clinically demonstrated or diagnosed in this case, despite the several VA clinical evaluations of the claimant. A chronic disease ... listed in 3.309 will be considered to have been incurred in service under the circumstances outlined in this section even though there is no evidence of such disease during the period of service. No condition other than one - 20 - listed in 3.309(a) will be considered chronic. 38 C.F.R. 3.307(a) (2002). COPD is not a disease listed in 3.309(a). A disease associated with exposure to certain herbicide agents means a chemical in @i herbicide used in support of the United States and allied military operations in the Republic of Vietnam during the period beginning on January 9, 1962, and ending on May 7, 1975. 38 U.S.C.A. 1116(a)(4) (West 2000); 38 C.F.R. 3.307(a)(6) 112002). A veteran who, during active military, naval, or air service, served in the Republic of Vietnam during the period beginning on January 9, 1962, and ending on May 7, 1975 and has a disease listed at 3.309(e) shall be presumed to have been exposed during such service to an herbicide agent, unless there is affirmative evidence to establish that the veteran was not exposed to any such agent during that service. The last date on which such a veteran shall be presumed to have been exposed to an herbicide agent shall be the last date on which he or she served in the Republic of Vietnam during the period beginning on January 9, 1962, and ending on May 7, 1975. "Service in the Republic of Vietnam" includes service in the waters offshore and service in other locations if the conditions of service involved duty or visitation in the Republic of Vietnam. 38 U.S.C.A. 1116(a)(3)(m) (2002); 38 C.F.R. 3.313(a) (2002). COPD is not one of the diseases listed at 3.309(e). It is the Board's responsibility to evaluate the credibility and probative value of proffered evidence in relation to the record in its whole. See, e.g., Owens v. Brown, 7 Vet. App. 429, 433 (1995); Guimond v. Brown, 6 Vet. App. 69, 72 (1993); Hensley v. Brown, 5 Vet. App. 155, 161 (1993). The Board places very little weight on the veteran's self-serving statements regarding either AO herbicide exposure or asbestosis exposure during active service as the cause of his current pulmonary disability, which is diagnosed as emphysema, or COPD, and which has been attributed by competent medical evidence and opinion to the claimant's 70-pack- year smoking history, which is clearly documented in the record. See Cartright v. Derwinski, 2 Vet. App. 24, 25 (1991) [interest may affect the credibility of testimony]. The Board finds that the veteran's statements are outweighed by his - 21 - official service medical records, including his service separation examination, which are devoid of reference to any chronic pulmonary disability or pathology. Self interest may effect the credibility of testimony, although not the competency to testify. Cartwright v. Derwinski, 2 Vet. App. 24, 25 (1991) An appellant's sworn statement, then, unless specifically found incredible or sufficiently rebutted, may serve to place the evidence in equipoise. The VA may not ignore the appellant's sworn testimony simply because he is an interested party. Smith, id., at 147, 148; Cartwright, id., at 24, 25. Credibility is a factual determination going to the probative value of the evidence, and is made after the evidence is admitted. Layno v. Brown, 6 Vet. App. 465, 469-70 (1994). ] The record in this case is silent for complaint, treatment, findings or diagnosis of a chronic pulmonary disability during active service, at the time of service separation examination, or at any time prior to October 1978, more than 11 years after final service separation. In addition, a report of medical examination for reenlistment in the Naval Reserve, conducted in October 1970, showed that the claimant's lungs and chest were normal, and a chest X-ray was negative. The claimant's original application for VA disability compensation benefits (VA Form 21-526), received in October 1978, made no mention of a pulmonary or lung disorder. The first evidence of a pulmonary disability in the claimant is dated in October 1978, when the claimant experienced a spontaneous right-sided pneumothorax, and underwent right and left thoracotomies with pleurodeses. No etiology of that condition was offered by the attending private or VA physicians. The claimant underwent a bilateral blebectomy for removal of emphysematous blebs, without complications, and postoperative treatment records showed that the claimant's lungs were clear, without rales, and a chest X-ray was described as looking good, with no evidence of pneumothorax. The treating physician noted that the appellant was continuing to smoke when discharged from the hospital in November 1978. - 22 - Based upon the foregoing, the Board concludes that a chronic pulmonary disability was nor incurred in or aggravated by active service; that continuity of post service pulmonary symptomatology has not been demonstrated; and that the record is devoid of competent medical evidence which links or relates any current pulmonary pathology to the claimant's period of active service. The claimant has further contended that his current pulmonary disability is residual to AO herbicide exposure or to asbestos exposure while aboard ship in the offshore waters of the Republic of Vietnam from 1965 to 1967. However, the record in this case is devoid of competent medical evidence or opinion which links or relates any current pulmonary disability in the claimant to AO herbicide exposure or to asbestos exposure while on naval active duty. The Board further notes that COPD is not a presumptive disability under the provisions of 38 U.S.C.A. 1110, 1101, 1112, 1113 (West 2000); 38 C.F.R. 3.307, 3.309(a), or 3.309(e) (2002). As noted, one of the pieces of critical evidence that served to reopen the claim was the March 1998 VA examination report indicating that as of that time, (i.e., 30 years after service), radiographic findings were consistent with a history of asbestos exposure. However, although the examiner reported that the appellant's VA claims folder had been reviewed, he further indicated that "medical records from that period of time are not available." The appellant's Social Security Administration file was subsequently received and included more comprehensive records of the development of the appellant's disorder, in particular the October 1987 spontaneous pneumothorax. Further, the March 1998 VA pulmonary examiner diagnosed chronic obstructive pulmonary disease, recommending further chest X-rays and pulmonary function tests (PFT's), and stated that if the PFT's indicate restrictive disease, part of that would be due to the obesity, although restrictive airway disease can be a result of asbestosis as well, so that would be a probable contributing factor. He further noted that if the chest X-ray showed plaques, such would be indicative of asbestos. He - 23 - expressed the opinion that the majority of the claimant's breathing problem was from obstructive pulmonary disease which was not from asbestos but was highly probably the result of his smoking history, while stating that if the PFT's showed restrictive disease, it would be his opinion that it was at least worsened by exposure to asbestos. However, in the event, the PFT's did not disclose restrictive disease in the claimant, but only the obstructive disease associated with the claimant's smoking history. To the same point, the October 2002 and January 2003 VA pulmonary examinations disclosed no X-ray evidence of calcified pleural plaques and no evidence of asbestosis, and PFT's on both occasions disclosed no findings of restrictive disease in the claimant, but only the severe obstructive disease which has been related to his smoking history. The examiner stated that it was his medical opinion that there was less than a 50 percent chance (i.e., less likely than not) that the claimant's current respiratory symptoms were due to inservice herbicide or asbestos exposure. The Board notes the claimant's reluctance to accept the medical evidence showing that his current COPD, which is his only diagnosed pulmonary disability, is related to his long-term history of heavy smoking, or his occupational exposure while working in a shipyard as a sand blaster and painter. Nevertheless, the record is silent for any opinion, other than the claimant's own lay opinion, which would support a belief that his current respiratory symptoms are the result of AO herbicide or asbestos exposure. Instead, the record consistently shows that his respiratory symptoms are due to COPD, which has been specifically related to his smoking history. Based upon the foregoing, and for the reasons and bases stated, the Board finds that service connection for a chronic pulmonary disability as residual to AO herbicide or asbestos exposure during active service is not warranted. Accordingly, the appeal for service connection for a chronic pulmonary disability as residual to AO herbicide or asbestos exposure is denied. In reaching its decision, the Board has considered the doctrine of reasonable doubt, however, as the evidence is not in equipoise, or evenly balanced, but is against the - 24 - claim, the doctrine is not for application. Gilbert v. Derwinski, 1 Vet. App. 49 (1990)/ ORDER Service connection for a chronic pulmonary disability as residual to AO herbicide exposure or asbestos exposure is denied. G.H.
