Lovastatin is a potent inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A reductase, which catalyzes the conversion of hydroxymethylglutaryl-coenzyme A to mevalonate, anearly and rate-limiting step in the synthesis of cholesterol. We studied the therapeutic effect and safety of lovastatin in 18 patients with nonfamilial primary hypercholesterolemia. Patients received 20mg/day lovastatin therapy as a single evening dose. If the total cholesterol level exceeded 200mg/dl after 2weeks of lovastatin therapy, the dosage of lovastatin was doubled. Mean percent total cholesterol level reductions from baseline were 26.4% and 31.9% after 4, and 8 weeks of lovastatin therapy respectively. Mean percent HDL-cholesterol level increase from baseline were 12% and 13% after 4, and 8 weeks of lovastatin therapy respectively. Adverse effects attributable to lovastatin were mild and temporary and no patient was withdrawn from therapy. We concluded that lovastatin was a well tolerated and effective agent for the treatment of nonfamilial primary hypercholesterolemia. Further studies are needed to establish the long-term safety and effectiveness of this drug.

We report a case of cutaneous metastatic carcinoma from an esophageal carcinoma in a 54-year-old male who complained of several pinhead-sized erythematous tender papules on the up-per chest. He had been admitted to the department of internal medicine for esophageal carcinoma. Radiological examinations revealed a luminal narrowing below the level of carina on esophagography, and a mass on the mid esophagus, left atrium and pulmonary vein on the chest CT scan. On endoscopy, about 30cm from the central incisor, a huge polypoid mass with a central ulceration and dirty surface margin was noted. Histopathological examination of the skin and esophageal biopsies showed the same atypical squamous cells with distinctive nucleoli, nuclear membrane and intercellular bridge, which were consistent with the squamous cell carcinoma of nonkeratinizing large cell type, suggesting these cutaneous lesions were metastasized from the esophageal carcinoma.

We report a case of malignant melanoma of soft parts presented with a hard mass on the dorsum of the left second toe. Malignant melanoma of soft parts has also been known as clear cell sarcoma of tendons and aponeuroses, which indicates the histologic feature of clear cell predominance and the origin of tumor cells, tendinous or aponeurotic structures. Although our case presented with many characteristic clinicopathologic features of malignant melanoma of soft parts, diagnosing this case as malignant melanoma of soft parts was made with great difficulty because of a rather unusual finding that the major cell component of neoplasm was spindle shaped cells in stead of clear cells. Cases featuring this distinctive histopathologic finding have not been reported individually to our knowledge, but described briefly in the literature. We think this case deserves special attention because of its close resemblance to various sarcomas.

Antihypertensive effect of angiotensin converting enzyme(ACE) inhibitor Captopril was studied in 34 cases of essential hypertension. A single oral dose of 50mg Captopril was administered daily and blood pressure was followed every 2 weeks. Diuretics were added to patients who responded inadequately after 2 weeks of Captopril single treatment. Alpha-blocker, beta-blocker or calcium channel-blocker was added to patients who responded inadequately after another 2 weeks of Captopril and diuretics combined treatment. In 5 cases, Captopril was raised to 100mg and further antihypertensives were added to unresponded 3 cases. The resuts were as follows; 1) In 15 patients, blood pressure dropped from 170.3+/-10.5mmHg/108.7+/-6.1mmHg to 148.3+/-4.4mmHg/93.3+/-3.7mmHg after 8 weeks of Captopril 50mg single therapy. 2) Hydrochlorothiazide 25mg was added to non-responders, and blood pressure dropped from 180+/-6.7mmHg/111.1+/-6.2mmHg to 155.0+/-15.0mmHg/106.2+/-8.7mmHg in 9 of 19 patients after 8 weeks of combined treatment. 3) Alpha-blocker, Beta-blocker or calcium channel blocker was added to 10 non-responders to Captopril-hyprochlorothiazide combination therapy, and blood pressure dropped from 189.0+/-27mmHg/116+/-10mmHg to 137.8+/-15.5mmHg/88.5+/-10.2mmHg after 8 weeks. 4) Increase of captopril from 50mg to 100mg in 5 random nonresponder cases of Captopril single treatment lowered blood pressure from 168.0+/-13.6mmHg/107.1+/-6.4mmHg to 161+/-15.2mmHg/99+/-8.8mmHg after 2 weeks. 5) Heart rate, and serum creatinine, electrolytes and lipid levels showed no significant interval change. 6) Six patients complained of dry cough and one patient complained of poor appetite but no other clinically significant complications were noted during Captopril treatment.

BACKGROUND: A sizable percentage of tuberculous pleurisy patients are known to have residual pleural thickening(RPT) despite adequate anti-tuberculous chemotherapy. But, the predictive factors related to the development of RPT is not well known. Therefore, we studied to determine which factors are related to the development of RPT after completion of therapy. METHODS: By retrospective review of medical records, fifty-eight patients initially diagnosed as having tuberculous pleurisy between March 1995 and January 1998 were separated into two groups: 27 patients in group 1 had RPT on simple chest radiography, while 31 patients in group 2 had no RPT after 6 month of anti-tuberculous chemotherapy. The clinical characteristics, radiologic findings and pleural fluid findings of the two group were compared at the time of diagnosis and during the course of therapy. RESULTS: 1) 47% of patients had RPT after 6 month of chemotherapy, and RPT was more common in man than in women(54% vs 29%,p=0.092). 2) In group 2 patients, complete resorption of pleural lesion occurred rather late stage of therapy(1-2 month : 26%, 3-4 month :29%, 5-6 month : 45%). 3) Group 1 patients had increased percentage of loculated pleural lesion(26% vs 19%) and increased white blood cell and lymphocyte count, lactate dehydrogenase level in pleural fluid (3527+/-5652 vs 2467+/-2201/ml, 2066+/-2022 vs 1698+/-1835/ml and 1636+/-1143 vs 1441+/-923IU/ml, respectively) than group 2 at the time of diagnosis, but statistically insignificant. 4) Duration of symptom prior to treatment, size of pleural effusion, presence of parenchymal lung lesion, level of total protein, glucose and adenosine deaminase(ADA) activity in pleural fluid were similar in both group. CONCLUSION: 53% of tuberculous pleurisy patients showed slow but complete resorption of pleural lesion after 6 month of chemotherapy. But, no clinical, radiological and pleural fluid findings are predictive for the development of RPT.

We investigated 97 right-handed comprehensive patients with unilateral hemispheric lesion confirmed by computed tomogram, to evaluate the presence of neglect syndrome by using tests of visual neglect, auditory extinction, and somesthetic extinction. The results are as follows: 1.Neglect syndrome was noted in 38.8% of right hemispheric lesion and 25.6% of left hemispheric lesion, the frequency of neglect syndrome was higher in new lesion(less than 1 month) than old(over than 1 month) and the common locations of neglect syndrome were parieto-occipital, temporo-parietal, fronto-temporo-parietal, and parietal in that order. 2. The severity of neglect syndrome showed higher correlations with right hemispheric lesion and new lesion, but without any significant correlation with the location of lesion.

PURPOSE: Rheumatoid arthritis (RA) is a common, chronic inflammatory arthritis that develops most often in women. Gonadal hormones may account for the sexual dimorphism in the immune response and for the greater incidence of autoimmune disease in females. Gonadotrophin-releasing hormone (GnRH), one of the gonadal hormones, plays an important role in immune system modulation. This study examined the effects of single nucleotide polymorphisms (SNP) in GnRH on gender differences in the pathophysiology of RA. MATERIALS AND METHODS: The presence of SNPs rs2659590, rs2321248, rs6186, rs6185, and rs2321049 in the human GnRH1 gene was confirmed in Korean RA patients by Taqman(R) SNP genotyping assays. A total of 153 unrelated female, Korean RA patients and 96 female Korean controls participated. RESULTS: There were no significant associations between GnRH1 polymorphisms and RA. However, we found that the rs2659590, rs6185 and rs2321248 polymorphism might be associated with a susceptibility to aberrantly high erythrocyte sedimentation rates in female RA patients. CONCLUSION: Additional studies, with a larger number of patients and in different populations will be required to assess whether GnRH1 polymorphisms and these haplotypes could be used as susceptibility or resistance markers in RA. To our knowledge, this study is the first to analyze associations between SNPs of GnRH1 and RA.

PURPOSE: We performed this study to investigate clinical and radiological features, CSF findings, clinical courses and prognostic factors of acute transverse myelitis(ATM) in pediatric patients. METHODS: A retrospective review of the medical records was performed for 15 patients with ATM under the age of 16 years from January 1997 to January 2007. RESULTS: The mean age at onset was 9.3+/-4.4 years, and the male to female ratio was 1.5:1. During the initial phase, the common presenting symptoms were back pain, abdominal pain, leg pain and weakness. Motor deficits progressed in all patients and urinary difficulty was found in 13 patients(86.7%). CSF leukocytosis was found in four patients and protein was elevated in nine patients among the 12 patients who underwent CSF study. On spine MRI, high signal intensity in T2-weighted image was mainly identified at the cervicothoracic level in 11 patients(73.3 %). According to Paines scale, 11 patients(73.3%) had normal or good outcomes. Favorable outcomes were associated with shorter duration of maximal neurologic deficits, an early recovery, and shorter interval to independent walking. In this study, we described two patients suffering from relapsing myelits without any association with a systemic disease. One patient was diagnosed as idiopathic recurrent transverse myelitis(IRTM) and the other was re-diagnosed as multiple sclerosis(MS). CONCLUSION: The prognosis of ATM in childhood is better than that reported for adults. The clinical symptoms and the extent of lesions in MRI were not correlated with outcomes. However earlier recovery was significantly associated with favorable outcomes.
