Heart-lung transplantation is a widely accepted treatment for Eisenmenger'syndrome. The patient is a 41-years-old male diagnosed with Eisenmenger'syndrome due to patent ductus arteriosus. The pressures were checked as follows: aorta 130/80 mean 100 mmHg, pulmonary artery 130/80 mean 109 mmHg, and right ventricle 130/20 mmHg, right atrium mean 20 mmHg. The patient needed heart-lung transplantation due to enlarged right pulmonary artery (diameter 7.5 cm). The donor was a 24 years-old male diagnosed as brain death due to subdural hematoma. Ligation of patent ductus arteriosus was performed under the cardiopulmonary bypass followed by heart-lung transplantation. Patient was extubated on postoperative day one, transferred to the general ward on day 3, and was discharged on postoperative day 33. Cardiac and lung biopsy was performed on postoperative day 41 with no signs of rejection.

Transbronchial fine needle aspiration(TBNA) is one of the cytologic methods in diagnosing lung cancers. TBNA can be used in cases of hilar, mediastinal or lung masses adjacent to the bronchi. We analyzed and compaired the findings of 27 cases of TBNA and bronchial washing and brushing(BW/BB) in lung cancers confirmed by either biopsy or surgical resection between Jun, 1996 and May, 1997 in Asan Medical Center. They were 18 cases of non-small cell carcinomas(eight squamous cell carcinomas, nine adenocarcinomas, and one large cell undifferentiated carcinoma), eight cases of small cell carcinomas, and one case of metastatic hepatocellular carcinoma. The sensitivity of TBNA was 37%(10/27) and false negative was 63%(17/27). Although the sensitivity of BW/BB w3s 56%(15/27), it was not different statistically from that of TBNA(Chi square, p=0.38). Overall sensitivity of TBNA and BW/BB in this series was 70%(19/27). Forty-seven percent of false negative TBNA(8/17) were positive in BW/BB. The findings suggest that the addition of TBNA to the standard BW/BB increases diagnostic yield in cytologic diagnosis of lung cancer.

Background: Acquired genetic alterations and presence of sensitizing mutations in the tyrosine kinase domain of EGFR and other signaling molecules have been found in different subsets of primary lung adenocarcinoma. The commonest EGFR mutations are small in frame deletions of exon 19 and a point mutation (L858R) in exon 21, having a combined occurrence of around 90%. The objective of this study was to determine the frequency and types of EGFR mutations in primary lung adenocarcinomas in Pakistan. Materials and Methods: EGFR mutations in tumor samples were screened by multiplex real time PCR. Briefly, DNA from formalin fixed paraffin-embedded tissue was amplified with primers and probes specific to 43 different EGFR mutations in a Cobas z 480 instrument. The assay detects mutations in four exons (18-21) of the EGFR gene. Results: Out of 94 patients, 65 were males and 29 females with a M:F ratio of 2.2: 1. The median age was 62 years (range, 28 - 85 years). In our biopsy samples 70 (74%) cases were of primary lung adenocarcinoma, whereas 24 (26%) were confirmed metastatic adenocarcinoma of primary lung origin. EGFR mutation was positive in 29% of the patients. The highest frequency of L858R was observed in 48% of these, followed by deletion in exon 19 (44%). In addition, other rare mutations such as compound G718X:S768I and insertions in exon 20 insertion were detected in approximately 4% of the patients. Conclusions: This study showed that Del 19 and L858R are the most frequent mutations in Pakistani lung adenocarcinoma patients and around 29% of the patients were found eligible for erlotinib therapy.

Desquamative interstitial pneumonia is an uncommon form of interstitial lung diseases and it has a good prognosis compared with other types of idiopathic interstitial pneumonia. A 69-year old man was admitted to our hospital because of a 3-month history of dyspnea. The patient presented with hypoxemia. High-resolution computerized tomography of the patient showed ground glass opacity and traction bronchiectasis with subpleural early honeycombing on the both lung fields. The pathologic findings of the video-assisted thoracoscopy lung biopsy were compatible with desquamative interstitial pneumonia, and irregularly distributed interstitial fibrosis and inflammation were observed at the peripheral parenchyme. Oral predinsolone was started; his symptoms and chest x-ray were improved, and so he stopped taking the prednisolone. Ten months later, the desquamative interstitial pneumonia recurred. We report here on a case of recurrent desquamative interstitial pneumonia with fibrotic lung disease.

Primary lung cancer frequently metastasizes to distant organs. But breast is a very rare site of metastasis. So, accurate diagnosis is essential to rule out primary breast cancer. A 62-year old woman who had complained of cough was diagnosed as small cell lung carcinoma of the right lower lobe. She had a 2.5cm sized lobular mass in left upper mid portion of breast. Sonoguided breast biopsy revealed small cell carcinoma consistent with metastatis from primary lung cancer. She also had bone metastses to the scapula and the vertebrae. We report the case of metastatic breast cancer from small cell lung carcinoma.

Background: Depression is a recognized complication of lung cancer underreported in developing countries such as Malaysia. Treating and identifying depression in cancer patients increases survival and quality of life. Our objectives are to study prevalence of depressive symptoms in newly diagnosed lung carcinoma, and examine the relationship of depressive symptoms with other influencing risk factors. Methods: A 2-year, cross sectional study February 2015-February 2017, was conducted at Hospital Tengku Ampuan Afzan, and Penang General Hospital. One hundred and three patients with newly diagnosed, biopsy confirmed primary lung carcinoma were recruited. Self-rated patient's identification sheet, validated Center for Epidemiologic Studies Depression (CES-D), and Dukes University Religion Index score from three different main languages were used. Results: Prevalence of current depressive symptoms (CES-D total score ${\geq}16$) is 37.9%. The result suggests prevalence of those at high risk of moderate to major depression, may need treatment. Multivariate analysis reveals those with good Eastern Cooperation Oncology Group factor (${\eta}2=0.24$, p<0.001) married (${\eta}2=0.14$, p<0.001) with intrinsic religiosity (IR) (${\eta}2=0.07$, p<0.02) are more resistant to depression. Conclusion: One in three of lung carcinoma patients, are at increased risk for depression. Clinicians should be aware that risk is highest in those with poor performance status, single, and with poor IR. We suggest routine screening of depression symptoms as it is feasible, to be performed during a regular clinic visit with immediate referral to psychiatrist when indicated.

The hamartoma is the commonest benign tumor of the lung and proved incidentally as asymptomatic coin lesion on routine chest radiologic examination, but has very low incidence, especially in endobronchial origin. The authors experienced a case of coincidental with intrapulmonary and endobronchial hamartoma. The patient, a 60-year-old man, a farmer, was admitted due to coughing and fever. Preoperative diagnosis was achieved by flexible bronchoscopic biopsy and managed by right middle lobectomy. Three lobulated masses were palpable in the right middle lobe. He was discharged on 15th postoperative day, without problem.

The endobronchial hamartoma is a relatively rare benign tumor of the lung. The symptoms of the endobronchial hamartoma are produced by obstruction of the bronchus and its sequelae. This patient was 51 year old male and complained dypnea, cough and purulent sputum for 2 years. On bronchoscopic view, a yellowish pedunculated mass nearly total occluding right main bronchial lumen was found. Endoscopic biopsy revealed squamous cell metaplasia of the bronchial mucosa. The operation was done with the right pneumonectomy. The pathologic result of the operative specimen was endobronchial hamartoma arisen from the right upper lobe bronchus.

Histological examination of biopsy or postmortem lung tissue from patients with asthma usually reveals thickened airway walls. This change is called airway remodeling, which is characterized by airway eosinophilia, hyperplasia of goblet cells and smooth muscle, and subepithelial fibrosis [1,2]. In this study, we investigated the time-course functional, morphological, biochemical changes of remodeling in a ovalbumin (OVA)-induced murine chronic asthma model. (omitted)

Pulmonary lymphangiomyomatosis is rare but extremely interesting condition caused by progressive widespread smooth muscle proliferation in the perilymphatic regions throughout the lungs. The patient was a 25-year-old female. She had angiofibromas in the face, and angiomyolipoma in the left kidney which was removed 5 years earlier. Three years ago she started having severe dyspnea with bilateral pneumothoraces. Treatment was initiated with bilateral closed thoracotomies followed by open thoracotomy through median sternotomy and lung biopsy, which revealed the diagnosis of pulmonary lymphangiomyomatosis. Recurrence of pneumothorax was treated by repeated chemical pleurodesis with tetracycline. She has been in good condition during medroxyprogesterone administration for 3 years.
