Menetrier's disease is characterized by enlarged gastric folds with foveolar hyperplasia and cystic dilatation of gastric glands. The additional biochemical features of hypoproteinemia, hypochlorhydria, and increased gastric mucus are often encountered. The pathogenesis and etiologic factors have not been clearly defined. In this report, we present two cases of Menetrier's disease in the stomach, one occurring in a 38-year-old male, associated with massive hematemesis, and the other in a 39-year-old male. Grossly, both cases showed marked giant gastric rugal folds resembling cerebral convolutions, sparing the antral portion. Microscopically, the giant gastric rugal folds consisted of the striking foveolar hyperplasia accompanied by an occasional presence of the smooth muscle fibers from the muscularis mucosa. The immunohistochemical stain revealed an intense positive reaction for transforming growth factor-alpha (TGF-alpha) and epidermal growth factor receptor (EGF-R) in the majority of mucous cells throughout the gastric mucosa and parietal cells, but did not reveal for epidermal growth factor (EGF). We suggested that TGF-alpha and EGF-R might be involved in the pathogenesis of Menetrier's disese.

Renal dysplasia results from aberrant metanephric histogenesis caused fundamentally by a defect in inducer tissue or responding tissue. Dysplastic kidneys vary tremendously in gross and microscopic appearance but are characterized by abnormal organization and a mixed population of primitive structures, such as fetal or immature cartilage, dysplastic ducts, immature tubules, and undifferentiated mesenchyme. We report a case of unilateral multicystic renal dysplasia associated with an ipsilateral ectopic ureteral orifice entering a seminal vesicle cyst in a 33-year-old man. He was admitted due to primary infertility which had developed three years ago. The his semen analysis revealed oligospermia. No evidence of a family history of renal dysplasia was reported. Microscopic examination showed that the entire kidney was composed of cysts lined by flattened cells, dysplastic ducts and immature tubules surrounded by collars of spindle cells, primitive mesenchyme, and a few aberrantly formed glomeruli.

Isolated rat thoracic aorta which is pharmacologically precontracted by phenylephrine induces photorelaxation when exposed to long wave length UV-light. The aim of the present study was to characterize the mechanism of UV-light induced by photorelaxation in the rat aorta. 1. UV light relaxed both endothelium-intact and -denuded rat aortic rings contracted by phenylephrine. The magnitude of relaxation on UV light was dependent on the exposure time and slightly greatly in endothelium-denuded rings than in endothelium-intact preparations. 2. L-NAME (10 nM-100 uM) but not D-NAME completely inhibited the photorelaxation in a concentration dependent manner. 3. The UV-induced relaxation was inhibited by methylene blue (1 -100 uM), and verapamil (100 nM), and removal of extracellular Ca2+. In contrast, UV-light induced photorelaxation was potentiated by N(w)-nitro-Larginine (L-NOARG) treatment. 4. In immunocytochemical analysis of UV-light induced iNOS and eNOS expression in rat aortas, at which expression levels were increased in a time-dependent manner on UV-irradiation in aortic endothelium and smooth muscle, respectively. These results suggest that UV light-induced photorelaxation may be due to nitric oxide from exogenously administered L-arginine as well as endogenous nitric oxide donors such as amino acid and arginine derivatives. Additional suggestion is that UV light stimulates the expression of nitric oxide synthases, and its activity for nitric oxide generation is dependent on cytosolic Ca2+ originated from extracellular space.

BACKGROUND: Silicone implants are frequently used in augmentation rhinoplasty in Asians. A common complication of silicone augmentation rhinoplasty is capsular contracture. This is similar to the capsular contracture after augmentation mammoplasty, but a classification for secondary contracture after augmentation rhinoplasty with silicone implants has not yet been established, and treatment algorithms by grade or severity have yet to be developed. METHODS: Photographs of 695 patients who underwent augmentation rhinoplasty with a silicone implant from May 2001 to May 2015 were analyzed. The mean observation period was 11.4 months. Of the patients, 81 were male and 614 were female, with a mean age of 35.9 years. Grades were assigned according to postoperative appearance. Grade I was a natural appearance, as if an implant had not been inserted. Grade II was an unnatural lateral margin of the implant. Clearly identifiable implant deviation was classified as grade III, and short nose deformation was grade IV. RESULTS: Grade I outcomes were found in 498 patients (71.7%), grade II outcomes in 101 (14.5%), grade III outcomes in 75 (10.8%), and grade IV outcomes in 21 patients (3.0%). Revision surgery was indicated for the 13.8% of all patients who had grade III or IV outcomes. CONCLUSIONS: It is important to clinically classify the deformations due to secondary contracture after surgery and to establish treatment algorithms to improve scientific communication among rhinoplasty surgeons. In this study, we suggest guidelines for the clinical classification of secondary capsular contracture after augmentation rhinoplasty, and also propose a treatment algorithm.

Xanthogranulomatous pyelonephritis is an uncommon entity of chronic renal infection and often misdiagnosed with renal tumor clinically. The characteristic examination are foamy histiocyte containing lipid material and foreign body giant cell forming granulomas, Macroscopically yellow nodules are present at the area of necrotic tissue. We have experienced a case of xanthogranulomatous pyelonephritis in 38 years old woman and reported with review of some literatures.

Primary meningeal melanocytoma of the central nervous system is extremely rare. We report a case of meningeal melanocytoma associated with Ota's nevus as a recurrent form in a 53-year old male. The meningeal melanocytoma was removed from right parietooccipital lobe 4 years ago and recurred in right parietal, occipital and left frontal lobes. Ultrastructurally, the tumor cells were characterized by the presence of numerous melanosomes and premelanosomes in their cytoplasm. Moreover, the tumor was lacking in histologic and ultrastructural features of pigmented meningioma, melanotic schwannoma and prolonged clinical course was different from primary meningeal melanoma or metastatic malignant melanoma.

Pulmonary blastoma is a family of tumors in which the glands or mesenchyme composing the neoplasm are primitive or embryonic in appearance. There are three subtypes, which include well differentiated fetal adenocarcinoma (pulmonary endodermal tumor), biphasic pulmonary blastoma, and cystic and pleuropulmonary blastomas in children. Among them, biphasic pulmonary blastoma is a primary malignancy of the lung originating from multipotential pulmonary blastema including both the malignant fetal epithelial and mesenchymal components. These make up 0.25 to 0.5 percent of all primary malignant lung tumors. This tumor is usually symptomatic and appears as a large, solitary peripheral mass, with a tendency to favor the upper lobe. Here we report a case where small sized asymptomatic peripheral lung mass was diagnosed as a biphasic pulmonary blastoma, prior to the operation, A subsequent percutaneous needle biopsy was performed, which revealed features of a large cell neuroendocirne tumor. In addition, a review of the relevant literature is provided.

Journal of the Korean Academy of Rehabilitation Medicine 1998;22(1):162-168
The purpose of this study was to evaluate clinical features of diabetic neuropahty. The clinical symptoms and signs were investigated in individuals with diabetes mellitus by a questionnaire of 17 items about motor, sensory, and autonomic symptoms and signs, and then electrodiagnostic study was performed. One hundred and one patients with diabetes mellitus aged 31 to 88 years participated. The most frequent complaint was tingling sensation in the distal extremities and the most frequent sign was decreased or absent ankle jerk. The least frequent symtom or sign was motor weakness. Eighty point two percent of patients showed electrodiagnostic abnormalities. Abnormal ankle jerk, tingling sensation, and paresthesia in patients with abnormal electrodiagnstic study were 60.5%, 58.0%, and 29.6%, respectively. Clinical diabetic neuropahty was diagnosed of the patients when both tingling sensation and decreased ankle jerk were present. We conclude that clinical symptoms and signs of diabetes mellitus may be useful for diagnosis of diabetic neuropathy.
