PURPOSE: This study was performed to find out the natural history of lung cancer in Pusan-Kyungnam area and changing of that in previous report. MATERIALS AND METHOD: We studied retrospectively 508 patients with pathologically proven lung cancer from January 1991 to December 1995. We analysed age and sex distribution, initial symptoms before diagnosis, first method yielding histologic diagnosis, cell types of lung cancer, initial stage of lung cancer, schema of overall patients, survivial of lung cancer patients, and prognostic factors affecting survival of lung cancer patients.. RESULTS: The overall male to female ratio was 4.5: 1 and the age distribution ranged from 20 to 86 years, and the median age of overall patients was 60 years. Histologic classification revealed that the most prevalent type was squamous cell carcinoma (251 cases, 49.4%), followed by adenocarcinoma (141 cases, 27.8%), small cell carcinoma (91 cases, 17.9%), and large cell carcinoma (3 cases, 0.6%). In non-smali cell lung cancer 56.8% were stage IIIb and IV, therefore curative operation was done in 18.7% of all cases, but in small cell lung cancer 65.6% were extended disease. Meidan survival of overall patients was 11.8 months. There was a quite difference in survival among the stages. In non-small cell lung cancer, median survival was 59.7 months, 27.3 months, 18.5 months, 12.7 months, 5.9 months in stage I, II, IIIa, IIIb, IV in each. In small cell lung cancer, median survival of limited disese was 12.2 months and median survival of extended disease was 6.7 months. The stage and the performance status were independent prognostic factors in both small cell and non-small cell lung cancer. CONCLUSION: The prognosis of patients with lung cancer was still grave, but the survival was better than that of a previous report. This may be accorded to increase in early diagnosis and operation and advance in supportive care.

Adult-onset Still's disease (AOSD) is an inflammatory disorder that's characterized by daily, spiking high fever, arthritis and an evanescent, salmon-pink rash. AOSD is diagnosed purely on the basis of the typical clinical features of the illness. The symptoms commonly include swelling of the lymph nodes, enlargement of the spleen and liver, and a sore throat. AOSD is difficult to differentiate from systemic lupus erythematosus (SLE) due to the similar clinical manifestations. We report here on a case of a 16-year-old female patient with autism and epilepsy and who complained of daily spiking fever for 20 days. The patient had maculopapular skin rashes on the face and whole body and lymphadenopathy. The liver function tests were elevated mildly. The initial rheumatoid factor (RF) and antinuclear antibody (ANA) tests were negative. We diagnosed her as having adult-onset Still's disease according to the criteria of Yamaguchi. We successfully treated her with oral prednisolone. But her antinuclear antibody test was changed to positive after discharge. So we finally diagnosed her as having SLE.

OBJECTIVE: We investigated the clinical and radiological advantages of unilateral laminectomy in posterior lumbar interbody fusion (PLIF) procedure comparing with bilateral laminectomy, under the same procedural condition including bilateral instrumentation and insertion of two cages, in patients with degenerative lumbar disease with unilateral leg symptoms. METHODS: We retrospectively reviewed 124 consecutive cases of PLIF via unilateral or bilateral approach between January 2006 and April 2010. In 80 cases (bilateral group), two cages were inserted via bilateral laminectomy, and in 44 cases (unilateral group), via unilateral laminectomy. The average follow-up duration was 29.5 months. The clinical outcomes were evaluated with the Visual Analogue Scale (VAS) and the Oswestry disability index (ODI). The fusion rates and disc space heights were determined by dynamic standing radiographs and/or computed tomography. Operative times, intra-operative and post-operative blood losses and hospitalization periods were also evaluated. RESULTS: In clinical evaluation, the VAS and ODI scores showed excellent outcomes in both groups. There were no significant differences in term of fusion rate, but the perioperative blood loss and the operative time of the unilateral group were lower than that of the bilateral group. CONCLUSION: Unilateral laminectomy can minimize the operative time and perioperative blood loss in PLIF procedure. However, the different preoperative disc height between two groups is a limitation of this study. Despite this limitation, solid fusion and satisfactory symptomatic improvement could be achieved uniquely by our surgical method. This surgical method can be an alternative surgical technique in patients with unilateral leg pain.

PURPOSE: The role of peritoneal washing cytology in determining further treatment strategies after surgery for gastric cancer remains unclear. One reason for this is the fact that optimal procedures to increase the accuracy of predicting peritoneal metastasis have not been established. The aim of this study was to evaluate the efficacy of cytology using samples harvested from two different abdominal cavity sites during gastric cancer surgery. MATERIALS AND METHODS: We prospectively recruited 108 patients who were clinically diagnosed with locally advanced gastric cancer (higher than cT1 stage disease). Peritoneal washing fluids were collected from the pouch of Douglas and the subphrenic area. Patients were prospectively followed up for 2 years to determine the recurrence and survival rates. RESULTS: Thirty-three patients dropped out of the study for various reasons, so 75 patients were included in the final analysis. Seven patients (9.3%) showed positive cytology findings, of whom, three showed peritoneal recurrence. Tumor size was the only factor associated with positive cytology findings (P=0.037). The accuracy and specificity of cytology for predicting peritoneal recurrence were 90.1% and 94.2%, respectively, whereas the sensitivity was 50.0%. The survival rate did not differ between patients with positive cytology findings and those with negative cytology findings (P=0.081). CONCLUSIONS: Peritoneal washing cytology using samples harvested from two different sites in the abdominal cavity was not able to predict peritoneal recurrence or survival in gastric cancer patients. Further studies will be required to determine whether peritoneal washing cytology during gastric cancer surgery is a meaningful procedure.

Right atrial aneurysm is a rare abnormality of unknown origin. Approximately half of patients with right atrial aneurysm show no symptoms. Right atrial aneurysm is usually detected by chance at any time between fetal and adult life and can be associated with atrial arrhythmia and systemic embolism. The diagnosis of right atrial aneurysm can be established with echocardiography, computed tomography (CT) or magnetic resonance imaging (MRI). Because of thromboembolic risk, aneurysmectomy is usually recommended. We review the case report of a 69-year-wold woman with right atrial appendiceal aneurysm, whose diagnosis was established by echocardiography and CT angiography.

Antiphospholipid syndrome(APS) is characterized by vascular thrombosis in association with elevated titers of antiphospholipid antibodies. Leg ulcers are a considered to be a cutaneous manifestation of APS due to thrombosis of small to medium sized vessels. We report a case of necrotic non-healing, ankle ulcers mimicking pyoderma gangrenosum associated with APS in 50-year-old man. He had a past history of autoimmune thrombocytopenia and cerebral infarction. Laboratory findings showed a circulating lupus anticoagulant, positive anticardiolipin antibodies as well as anti-dsDNA and anti-Sm antibodies. Skin biopsy of ulcer lesions showed thrombotic vasculopathy of medium sized vessels with minimal leukocyte infiltration. Ulcers were successfully treated with surgical debridement and subsequent skin graft along with anticoagulation therapy.

PURPOSE: Radiotherapy for head and neck cancer does not impair the voice quality as much as laser treatment or surgery, but it can induce muscle wasting and fibrosis and symptoms of dry mouth. We investigated the effect of irradiation on the myosin heavy chain (MyHC) expression in laryngeal muscles. MATERIALS AND METHODS: Rats were irradiated with one dose of 10, 15, 20, 25, 30, or 35 Gy and other rats were irradiated with 20 Gy. The thyroarytenoid (TA), posterior cricoarytenoid (PCA), and cricothyroid (CT) muscles were subjected to reverse transcription-polymerase chain reaction (RT-PCR). RESULTS: Two weeks after irradiation with 10, 15, or 20 Gy, all the MyHC type expressions had decreased in a dose-dependent manner in the TA, PCA, and CT muscles, and especially the expression of MyHC IIa decreased much more than the expressions of the other MyHC isoforms in all muscles. In the 20 Gy-irradiated rats, almost all the MyHC isoform expressions declined over 12 weeks in the TA, PCA, and CT muscles, except for the MyHC I expression in the PCA and CT muscle. The MyHC IIa expression was markedly decreased in all the muscles. CONCLUSION: The laryngeal muscles responded differently to radiation, but they showed a time-dependent and long-lasting decrease in the expressions of all the MyHC isoforms in the TA, PCA, and CT muscles. In particular, the expression of the MyHC IIa isoform in all the muscles may be more sensitive to irradiation than the expressions of the other MyHC isoforms.

Although arthralgia with or without hyperuricemia commonly occurs in a patient receiving antituberculous treatment including pyrazinamide, acute gouty arthritis is rarely reported. Here we report a case of acute gouty arthritis presented after antituberculous treatment in a patient with asymptomatic hyperuricemia and mild renal insufficiency. A 76-year-old woman complained sudden onset of painful swelling in both first metatarsophalangeal joints 9 weeks after antituberculous treatment. She had hypertensive nephropathy with mild renal insufficiency and asymptomatic hyperuricemia for 8 years. Needle aspiration of the joint fluid demonstrated needle-shaped strongly negative birefringent monosodium urate crystal. The painful swelling improved with steroid and colchicine.
