Abstract

Background: Residual pleural thickening (RPT) is the most frequent complication of tuberculous pleurisy (TP), and this can happen despite of administering adequate anti-tuberculous (TB) therapy. Yet there was no definite relation between RPT and other variables. The aim of this study was to examine matrix metalloproteinases (MMPs) and the inhibitors of metalloproteinases (TIMPs) and to identify the factors that can predict the occurrence of RPT. Methods: The patients with newly-detected pleural effusions were prospectively enrolled in this study from January 2004 to June 2005. The levels of MMP-1, -2, -8 and -9, and TIMP-1 and -2 were determined in the serum and pleural fluid by ELISA. The residual pleural thickness was measured at the completion of treatment and at the point of the final follow-up with the chest X-ray films.Results: The study included 39 patients with pleural fluid (PF). Twenty-three had tuberculous effusion, 7 had parapneumonic effusion, 7 had malignant effusion and 2 had transudates. For the 17 patients who completed the anti-TB treatment among the 23 patients with TP, 7 (41%) had RPT and 10 (59%) did not. The level of PF TIMP-1 in the patients with RPT (41,405.9±9,737.3 ng/mL) was significantly higher than that of those patients without RPT (29,134.9±8,801.8) at the completion of treatment (p=0.032). In 13 patients who were followed-up until a mean of 8±5 months after treatment, 2 (15%) had RPT and 11 (85%) did not. The level of PF TIMP-2 in the patients with RPT (34.4±6.5 ng/mL) was lower than that of those patients without RPT (44.4±15.5) at the point of the final follow-up (p=0.038).Conclusion: The residual pleural thickening in TP might be related to the TIMP-1 and TIMP-2 levels in the pleural fluid.

Abstract

Background: Lung cancer is the leading cause of cancer death in South Korea since the year 2000 and it is more common in elderly patients, with a peak incidence at around 70∼80 years of age. However, these elderly patients receive treatment less often than do the younger patients because of organ dysfunction related to their age and their comorbidities, and they show poor tolerance to chemotherapy. The aims of this study were to analyze the clinical characteristics and treatment-related survival of elderly patients with lung cancer.Methods: In this retrospective study, we analyzed the clinical data of 706 lung cancer patients who were diagnosed at hospitals in Daegu and Gyeongsangbukdo from January 2005 to December 2005. We compared the clinical characteristics and outcomes of the patients who were aged 70 years and older (elderly patients) with those clinical characteristics and outcomes of the younger individuals. Results: The median age of the patients was 68 years (from 29 to 93) and the elderly patients were 38.7% (n=273) of all the study’s patients. Squamous cell carcinoma was the most common type of lung cancer in both the elderly and younger patient groups. Elderly patients had more symptoms of dyspnea and chronic obstructive pulmonary disease (COPD) than the younger patients (p<0.001 and p<0.001, respectively). A good performance status (ECOG 0-1) was less common for the elderly patients (p<0.001). The median survival of the non-small cell lung cancer (NSCLC) patients was significantly higher in the younger patient group than in the elderly patient group (962 days vs 298 days, respectively, p=0.001). However, the median survival of the NSCLC patients who received any treatment showed no significant difference between the younger patient group and the elderly patient group (1,109 days vs 708 days, respectively, p=0.14).Conclusion: Our data showed that appropriate treatment for selected elderly patients improved the survival of patients with NSCLC. Therefore, elderly NSCLC patients with a good performance status should be encouraged to receive appropriate treatment.

Abstract

Background: Thymic epithelial tumors are the most common tumors affecting the anterior mediastinum. The aim of this study is to investigate clinical features of the patients who were diagnosed with thymic epithelial tumors at Pusan National University Hospital. Methods: We retrospectively reviewed the records of thirty-seven patients who were diagnosed with thymic epithelial tumors from Jan. 1997 to Jan. 2007. The pathological classification and clinical stage of the thymic epithelial tumors were based on the WHO classification and Masaoka's staging system. A total 37 patients were enrolled: 23 were males and 14 were females, and their mean age was 51.3 years.Results: Thirty patients presented symptoms at the time of diagnosis and their symptoms were as follows: chest pain (53%), dyspnea (23%), and cough (17%). Myasthenia gravis was diagnosed in five patients. With respect to the tumor staging, three cases (8%) were stage I, 10 cases (28%) were stage II, 12 cases (32%) were stage III, 6 cases (16%) were stage IVA and 6 cases (16%) were stage IVB. Twenty-four cases (67%) displayed stage III or IV disease. The pathological types according to the WHO classification were as follows: B1 (32%), C (23%), B3 (20%), B2 (16%), AB (6%) and A (3%). Twenty-four patients underwent thymothymectomy and four of these patients relapsed. Stage III or type B3 was common in the relapsed patients. Five patientsexpired. Stage IV or type B3 and C were common in the expired patients.Conclusion: In this study, stage III or IV disease and type B3 or C were common at the time of diagnosis and these findings might contribute to postoperative recurrence and a poor outcome.

Abstract

Catamenial hemoptysis is a rare condition that’s characterized by recurrent hemoptysis occurring in association with menstruation, and this is associated with the presence of intrapulmonary or endobronchial endometrial tissue. The diagnosis of pulmonary endometriosis can be made according to a typical clinical history and with exclusion of other causes of recurrent hemoptysis. Treatment of pulmonary endometriosis can be medical or surgical; however, the optimal management of this condition is still a matter of debate. Medical therapy may be problematic, due to recurrence of symptoms despite hormonal ablation, and adverse effects from long-term hormone therapy can also be a problem. We report here on a case of pulmonary endometriosis in a 23-year-old woman who presented with hemoptysis that occurred during the first 3 days of menstruation, and this happened over a 4 month period. She was successfully treated by video-assisted thoracoscopic surgery (VATS). No more hemoptysis was noted during 12 months of follow-up.

Abstract

Pregnancy induces many physiologic changes, and it can cause hemoptysis in relation to the underlying or potential pulmonary diseases. Although hemoptysis is not a frequent event during pregnancy, a thorough search for its etiology and then immediate management should be initiated for a case of massive hemoptysis to avoid serious adverse effects on both the fetus and the mother. Most hemoptysis events during pregnancy are related to well known etiologies, but there are a few reported cases of hemoptysis in pregnant women who are without any underlying lung lesion. We report here on a case of a pregnant woman with total lung collapse due to hemoptysis, and a thorough search for the etiology after delivery could not reveal any etiology.

Abstract

Nephrotic syndrome is a relatively rare complication of malignancy. A few cases of nephrotic syndrome accompanying Hodgkin's disease, non-Hodgkin lymphoma, leukemia and other malignancies have been reported since the first case of the nephrotic syndrome associated with extrarenal malignancy was reported in 1922. Hodgkin's disease and solid tumors are known to be the most common malignancies accompanying nephrotic syndrome. The pathologic findings of kidney in patients with Hodgkin's disease commonly show minimal change nephropathy. Membranous glomerulonephropathy is the most common pathologic feature in patients with solid tumors. Although membranous glomerulonephropathy related to small cell lung cancer has rarely been reported in Korea, minimal change nephropathy accompanying small cell lung cancer has never been reported. We present here a case of a 70 year-old male with minimal change nephropathy that was related to small cell lung cancer. We detected small cell lung cancer during the diagnosis work-up of nephrotic syndrome. We suggest that nephrotic syndrome can be a manifestation of underlying malignancy.

Abstract

Bronchial mucoepidermoid carcinoma is uncommon, representing 0.2% of all lung tumors. The disease usually presents with symptoms of airway obstruction and recurrent pneumonia. It is commonly classified into two grades in Korea, low and high. We report a case of a bronchial mucoepidermoid carcinoma in a 40-year-old woman who complained of symptoms of an upper respiratory infection. The histological grade after a bronchoscopic biopsy was intermediate. A left upper lobectomy was performed as treatment. The TNM stage of this case was IA (T1N0M0). In addition, 25 cases of bronchial mucoepidermoid carcinoma from 1984 in Korea are also reviewed from the viewpoint of the relationship between the histological grade, TNM stage and clinical course of the tumor.

Abstract

We report a case of acute myeloid leukemia with multilineage dysplasia accompanying malignant pleural effusion. A 73 year-old male patient was admitted complaining of febrile sensations and right chest pain. The cytology of the pleural fluid revealed malignant pleural effusion showing many blasts, which had previously been identified in his bone marrow when he was diagnosed with acute myeloid leukemia with multilineage dysplasia two months earlier. His age and poor general condition had precluded chemotherapy with the exception of hydroxyurea and conservative treatment. Unfortunately, he succumbed to the disease 4.5 months after diagnosis. This case highlights the importance of determining if the pleural effusion of acute leukemia is malignant or not because it can suggest a pleural metastasis and influence the prognosis.

Abstract

Sarcoidosis is a systemic granulomatous disease that primarily affects the lung and lymphatic system of the body. Since Brincker first noted a statistically significant increase of malignant tumors among sarcoidosis patients, there have been several reports on simultaneously developed sarcoidosis and malignancy. A 30-year-old man was admitted to our hospital because of multiple enlarged mediastinal lymph nodes. The patient had been well until approximately 10 days before admission, when he developed a cough. Chest X-ray and computed tomography (CT) of the chest that were performed at the outpatient department revealed multiple enlarged mediastinal lymph nodes. Cervical lymph node biopsy revealed both non-caseating granuloma and metastatic papillary carcinoma, whereas the mediastinal lymph node showed only non-caseating granuloma. The thyroid gland surgical specimen showed papillary carcinoma. We report here on a case of a 30-year-old man who had sarcoidosis and thyroid cancer, and we include a review of the literature.

Abstract

A fifty-seven year old female patient visited the emergency department with tachypnea and a decreased mental status. The patient had been receiving fluid therapy at home and a bolus of air was injected into the fluid bottle in order to increase the infusion speed. Chest computed tomography revealed air in the left brachiocephalic vein that was accompanied with pulmonary edema the diagnosis of venous air embolism was made. Venous air embolism can result from various procedures that are performed in almost all clinical specialties and they can be fatal in cases of massive air embolism. Therefore, it is important for all clinicians to be aware of this problem.
