Primary hypothyroidism can result in reactive enlargement of the pituitary gland which is indistinguishable from primary pituitary lesions in clinical presentation and on magnetic resonance imaging. A 17-year-old girl came to the hospital due to short stature, general weakness and galac-torrhea. The magnetic resonance imaging (MRI) study showed pitutary enlargement. The hormone study showed hyperprolactinemia, decreased basal growth hormone level and primary hypothyroi-dism. By thyroid replacement therapy only, mass was successfully regressed on follow up MRI after 4 months, and growth acceleration could be achieved.

BACKGROUND: Insulin resistance syndrome shows extreme insulin resistance and is associated with acanthosis nigricans. We can differentiate it into type A insulin resistance that has insulin receptor defect, and type B insulin resistance due to insulin receptor autoantibody. Type B insulin resistance was firstly described by Kahn in 1976. It was often found in adult female and showed autoimmune characteristics. As clinical characteristics, there are hyperglycemia, hypoglycemia, hyperinsulinemia, extreme insulin resistance and acanthosis nigricans. METHODS: We investigated 17 insulin receptor autoantibody positive cases and 8 cases of normal control who had visited Wonju Christian Hospital from October 1994 to December 1995. Among insulin receptor autoantibody positive subject, male was 4 cases and female 13 cases. Their mean age was 42.2. We compared patients who had insulin receptor antibody positive acanthosis nigricans(IRA) with normal controls. IRA patients were 6 cases(35.3%) of nomal glucose tolerance, 11 cases(64.7%) of abnormal glucose tolerance including overt diabetes mellitus. RESULTS: The 11 cases(64.7%) among IRA patrents were obese and 13 cases(76.5%) had hyperininsulinemia. In IRA patients, mean serum insulin concentration during oral glucose tolerance test was 202.1mU/mL and it was greater than 46.3 of normal controls. Insulin sensitivity in 1.79mg/L * mM * xmU * min normal controls was higher than 0.74mg/L * mM * min of IRA patients. CONCLUSION: IRA patients showed abnormal glucose tolerance including overt diabetes millitus, severe insulin resistance, hyperinsulinemia and obesity.

The incidence of primary lung cancer is increasing in our country. This presentation is an attempt to correlate a useful diagnosis with radiological findings of primary lung cancer. Histologically proved 210 cases of primary lung cancer are as follow: Epidermoid Ca. 65%, Adeno Ca. 18%, Small cell Ca. 9.5%, Large cell Ca. 2%, Unclassified Ca. 3.3%, Mucoepidermoid Ca. 2.4%, Mixed Ca. 0.5%. 3. In smoking history; 91% of epidermoid Ca, 17%of small cell Ca. 30% of adeno Ca. has smoking history. 4. In mass size; Average diameter of mass was most was5.3cm. Hilar mass was seen in 48 cases. Hilar mass was most frequent finding in small cell Ca. and the peripheral mass in adeno Ca. 5. Cavitary lung Ca. was 26 cases (12.4%) and most cases had relative thick wall and its mean thickness was 3.6mm. 6. Coexistence of pulmonary tuberculosis and lung cancer was 22 cases (10.5%), and most common in epidermoid cell Ca. as 16 cases. 7. Other findings include metastasis to lymph node, bone and other organ, and pleural effusion.

Autophagy is a life-sustaining process by which cytoplasmic constituents are segregated in double-lipid bilayer membrane vesicles and undergo degradation into lysosomes. In recent studies, the basal autophagy is an indispensable process mediating proper vascular function in the body. Moreover, autophagy activated by many stress-related stimuli in the arterial wall protects endothelial cells and smooth muscle cells against cell death and the progression of vascular disease including atherosclerosis. Autophagy is protective to atherosclerosis during early stage but becomes dysfunctional in advanced atherosclerotic lesions. Following this finding, the need is emphasized which pharmacological development with compounds that activate the protective effects of autophagy in the vascular disease. Autophagy stimulated by oral or vascular delivery of rapamycin or derivatives effectively suppressed the atherosclerotic plaque growth and plaque destabilization. In this review, the recent finding is summarized on the role of autophagy in atherosclerosis and find out whether the activation or rescue of autophagy could provide a breakthrough in the treatment of atherosclerosis.

Thyroid tuberculosis is rare. We experienced case of a 50-year-old woman with tuberculosis of the thyroid associated with miliary tuberculosis. She complained of chronic cough and weight loss. She was clinically and biochemically euthyroid. Thyroid sonogram demonstrated 3 2 cm sized heterogenous echogenic mass on upper pole of the left lobe of thyroid with calcification. Fine needle aspiration biopsy showed epithelioid granuloma in the caseous necrosis and acid-fast bacilli. She took antituberculous agents. One month later, radiologic finding improved and thyroid mass decreased also.

Subarachnoid-pleural fistula after routine thoracotomy is a rare complication but a very serious problem. Twenty one cases have been reported in the literature. We report a care of subarchnoid-pleural fistula that dveloped after the esecation of posterior mediastinal neurogenic tumor. The patient presented with large amount of clear pleural fluid with mild headache and dizziness. Surgical intervention following a trial of conservative therapy was undertaken because we strongly suspected subarachnoid-pleural fistula. A dural tear was found at the level of resected intercostal nerve root. The dura was closed by way of direct suture and fibrin glue. In this case, the recognition of subarachnoid-pleural fistula formation is difficult because the patient had not presented any neurologic deficit.
