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 efficiency of lipid extraction by different kinds of solvents from stratum corneum may vary. OBJECTIVE: To assess the efficiency of lipid extraction by several solvents from the stratum corneum, the total lipids weights were measured by an electronic microbalance, and lipids compositions of a stratum corneum were analyzed by thin layer chromatography(TLC) after pretreatment of several solvents, respectively. METHODS: Stratum corneums separated fro circumcised prepuce were pretreated with acetone, petroleum ether, or distillecl water for 10 minutes. Lipids of stratum corneum were extracted with methanol chlorofonn-H,O mixture(4: 2: 1.6, v/v, Bligh Dyer solvent). Lipids weights were weighed, and the ratio of lipid weight and wet weight of stratum corneum were measured. TLC was performed and lipids compositions were quantitated by photodensitometer. Lipids extraction in viva was performed on both forearms. After two times stripping with sellotape, lipids were extrected with the solvents using cup method. These were dried and lipids weights were weighed. RESULTS: The efficiency of lipid extraction from the stratum corneum of circumcised prepuce were acetone, petroleum e1 her, and distilled water in decreasing order. All groups were similar in the compositions of the stratum corneum lipids except for those of cholesterol esters and sphingolipids. The efficiency of lipid extraction from in vivo skin were ranked in order from petroleurn ether, acetone, down to distilled water. The efficiency of lipid extraction of petroleum ether and acetone were higher than that of distilled water. CONCLUSION: The efficiency of lipid extraction is influenced by the kinds of solvents as well as the materials and the methods of extraction.

An external thrombotic hemorrhoid is a very painful disease with a high incidence rate. The chief complaints encountered by the surgeon are protrusion and pain. However, because the spontaneous healing rate is very high, there is no consensus on whether conservative management or surgery is a more effective treatment policy. In an attempt to resolve this problem, we performed a clinical analysis of fifty patients with external thrombotic hemorrhoids who were treated by conservative management at Song-Do Colorectal Hospital from October 1996 to December 1996. We recorded the time required for the protrusion and the pain to disappear and performed manometry to check the sphincter pressure and tissue pathology to determine the pathogenesis of the external thrombotic hemorrhoid. The results are as follows: 1) Based on pathology, the cause of the external thrombotic hemorrhoids was venous thrombosis due to venous stasis, not a hematoma due to venous rupture. 2) Manometry showed that the resting sphincter pressure and the squeezing sphincter pressure for the patients with external thrombotic hemorrhoids was higher than those of the control group, which was the reason for the venous stasis. In conclusion, because an external thrombotic hemorrhoid is just a thrombosis due to venous stasis, the thrombosis can be improved by using methods such as a warm sitz bath and analgesics to decrease the sphincter pressure. Hence, conservative management should be the preferred treatment in almost all cases.
