Meralgia paresthetica is a syndrome consisting of numbness, pain, tingling, burning and/or a variety of other paresthesias on the distribution of the lateral femoral cutaneous nerve (LFCN) of the thigh. We report a case of meralgia paresthetica in a 41-year-old woman who complained of the symptoms of pain, burning sensation, and dysesthesia which occurred whilst standing up without any other constitutional symptoms. The authors suspect that frequent. and persistent squatting may play a role in the development of the present symptoms.

BACKGROUND: The changes in lipid composition during epidermal differentiation has been reported in human and animal models. Because of the difficulties in getting adeguate specimens from human subjects, the authors used easily obtainable circumcised prepuce for lipid analysis. OBJECTIVE: To investigate the changes in lipid composition duriig cornification of the epidermis, the lipid compositions of whole epidermis and stratum corneum were analyzed by thin layer chromatography(TLC). METHODS: From circumcied prepuce whole epidermis and stratum orneum were separated by 10mM EDTA(ethylene diamine tatraacetate) in PBS(phosphate-buffered saline) or heat(60C), and 0.5% trypsin in PBS respectively. Lipids were extracted with methanolctloroform-HO mixture(4:2:1.6, v/ v, Bligh-Dyer solvent), TLC was performed and lipid composition was quantitated by photodensitometer. RESULTS: In the composition of stratum corneum lipids, sphingoliids were the highest(33.3+2.9%) followed by cholesterol, free fatty acids and cholesterol esters in cleceasing order, there were small percentages of triglycerides, cholesterol sulfate and squalene. CONCLUSION: In this study the lipid composition of epidermis was similar to that of stratum corneum rather than those of previous reports on epidermal lipids, which may indicate the regional characteristics of epidermal/stratum orneum lipids in hyperkeratotic prepuie.

BACKGROUND: Recent evidences suggest that anesthetic action within the spinal cord is important in suppressing somatic responses to painful stimuli. Intrathecal endothelin-1 (ET-1) is known to have antinociceptive effect. The purpose of this experiment was to determine whether intrathecal ET-1 may influence the minimum alveolar concentration (MAC) of isoflurane in rats and access the role of the spinal cord as the sites of anesthetic action in blocking somatic responsiveness. METHODS: In Sprague-Dawley rats fitted with an indwelling intrathecal catheter, we determined the MAC of isoflurane using a tail-clamp technique as a painful stimulus, combined with end-tidal anesthetic sampling. In experiment 1, the control MAC was determined and changes of control MAC were observed after intrathecal ET-1 (4x10-2 nmol, 4x10-3 nmol) administration. In experiment 2, we observed the effects of L or N type Ca++ channel blocker such as verapamil (50 g) or W-conotoxin (0.5 g) on the MAC after measurement of the control MAC. In experiment 3, after measurement of the control MAC, ET-1 (10-2 nmol) was administered intrathecally and the MAC was determined again. Next, intrathecal verapamil (50 g) or W-conotoxin (0.5 g) was injected. After that, the MAC was determined again. RESULTS: In experiment 1, ET-1 decreased the MAC of isoflurane and its effect was sustained over 2 hours. In experiment 2, the MAC, determined following administration of verapamil or W-conotoxin, was not different from that of the control. In experiment 3, the MAC was decreased after ET-1 administration and then increased following injection of verapamil or W-conotoxin. CONCLUSIONS: These results suggested that ET-1, in relation to calcium, might play an important role in determining the MAC of isoflurane in the spinal cord.

Weber-Christian disease is an inflammatory disease of subcutneious fat tissue which is clinically characterized by relapsing, febrile, nodular, nonsuppurative pannicutilitiy. The cause is unknown, but the disease has been attributed to an autoimmune reaction, infectioris, halogen compounds, sarcoidosis, SLE and a-antitrypsin deficiency. We report here in a case of Weber-Christian disease in a 8-year-old girl, who had indurated erythemataus subcutaneous nodules on the extremities, buttock and trunk accompanied by various general symptoms such as fever, malaise, arthralgia and edema of the abclorren and legs. This case was successfully treated with dapsone,

A clinical and histopathological study was performed on ninety-four patients with nephrotic syndrome (91 idiopathic and 3 secondary) who were admitted to Department of Internal Medicine, Yeungnam University Hospital during the period of nine years, from January 1985 to May 1994. The results were as following. 1. the ratio of male to female was 1.76:1. In young age group, minimal change was the most predominant type. In old age group, membranous glomerulonephritis and focal glomerulosclerosis were predominant types. 2.- The primary nephrotic syndromes were 96.8% and secondary nephrotic syndromes were 3.2%. Histopathologic findings of 94 renal biopsy tissue were classified into minimal change (43.6%) mesangial proliferative glomerulonephritis (29.8%), membranous glomerulonephritis (12.8%), Typel membranous proliferative glomerulonephritis (4.3%), focal glomerulosclerosis (3.2%) .and others (6.4%). 3. The response of eighty-six patients treated with steroid showed complete remission in 51.2%, partial remission in 20.9%, steroid dependent in 2.3%, and no effect in 25.6% of cases respectively. The response to steroid therapy was most effective in the patients with minimal change lesion. 4. In the patient with membranous proliferative glomerulonephlitis, long-term angiotensin converting enzyme inhibitor treatment showed less deterioration of renal function.

We report a case of infantile acute hemorrhagic edema in a 15-month-old boy. The patient showed multiple, bean to walnut-sized, red to purple-colored, indurated purpura with a cockade pattern on the face, earlobes, and extremities. Edema of the hands, feet, and earlobes was also observed. Laboratory examinations showed thrombocytosis, decreased serum CH50, and ketone in the urine. A skin biopsy taken from indurated purpura on the lower leg exhibited findings of acute leukocytoclastic vasculitis. Direct immunofluorescence examination showed deposition of IgM along the dermo-epidermal junction and C3 in the dermal vessel walls. With-out specific management except for fluid therapy to correct dehydration, the skin lesions cleared completely in 2 weeks, and recurrence has not observed.
