In treatment of Vitamin D-resistant rickets, the authors supplemented supramalleolar stepcut osteotomy for complex deformity of tibia consisted of varus, anterior bowing and intemal torsional supramalleolar level which accompanied severe waddling gait. The results of 10 tibia operations from 5 patients were generally satisfactory in terms of appearance and function.

Polyethylene glycol (PEG)-3350 is the most frequently used lavage solution for bowel cleansing prior to colonoscopy or elective surgery because its large molecular weight means that it is poorly absorbed. However, if it leaks into the peritoneal cavity, complications may arise. Few published studies have assessed the absorption, distribution, metabolism and excretion of PEG. Moreover, no published clinical data regarding complications due to the intra-peritoneal leakage of PEG-3350 could be found. We report on an elderly patient who developed the poisoning caused by leaking of PEG-3350 during bowel preparation. It resulted in severe metabolic acidosis, hypernatremia, hyperosmolality and a high anion gap, but it was effectively treated with early continuous renal replacement therapy after surgery.

BACKGROUND: Intracellular calcium overload is a common final feature of the ischemic-reperfused heart and mediates the genesis of irreversible cell damage. Reactive oxygen medabolites have been known to play and important role as toxic mediators in myocardial injuries resulting from ischemia and reperfusion. In order to investigate the mechanism of intracellular calcium accumulation in the ischemic-reperfused myocardium, the present study observed the possible contribution of the reactive oxygen metabolite to the calcium transport of cardiac mitochondria. METHODS: Mitochondrial were isolated from rabbit hearts. The effects of a reactive oxygen metabolite, H2O2 on calcium uptake and release, redox states of endogenous pyridine nucleotides and glutathiones of mitochondria respiring with succinate were observed. Calcium uptake and release were monitored by dual-wave length spectrophotometer using a calcium indicator, arsenaze III. Contents and redox states of pyridine nucleotides and glutathiones were measured by enzymatic methods using spectrofluorometer and HPLC. RESULTS: Hydrogen peroxide(10-500microM) promoted calcium release dose-dependently from CA++-preloaded mitochondria, but did not affect the mitochondrial calcium uptake. The H2O2-induced calcium release was accompanied by simultaneous oxidation of the pyridine nucleotides and decrease in the content of the reduced form of glutathione(GSH). When mitochondria were treated with BCNU(N,N=bis(2-chloroethyl)-N-nitrosourea) to inhibit glutathione reductase and so as to reduce the GSH content, there were no increase in calcium release from the mitochondria. These results may indicate that H2O2 increases the permeability of cardiac mitochondrial membrane to calcium in association with the changes in redox state of endogenous pyridine nucleotides, but not with that of glutathiones. CONCLUSION: It is suggested that the reactive oxygen metabolites induce the release of calcium from mitochondria by altering the redox state of pyridine nucleotides, and it may partly be involved in the elevation of cytosolic calcium concentration in the ischemic-reperfused myocardial cells.

Secondary cutaneous cryptococcosis may occur earlier than other manifestations of disseminated cryptococcosis. A 68-year-old woman presented with multiple ulcerative lesions on the right calf of 2 weeks duration. She had been treated with antibiotics, but the lesions spread rapidly. The initial clinical impression was necrotizing fasciitis, but routine KOH mounting from the ulcerative lesions showed numerous budding yeast cells with peripheral clear zones and further investigations including a skin biopsy, tissue cultures and India ink preparations allowed a rapid and definitive diagnosis of cutaneous cryptococcosis. Studies for other evidence of infection elsewhere revealed an asymptomatic pulmonary lesion. We report a case of secondary cutaneous cryptococcosis clinically mimicking necrotizing fasciitis that occured before other manifestations of disseminated cryptococcosis.

Although the management of fractures of the calcaneus still remains controversial, open reduction and internal fixation is gaining in popularity as the method of choice for the treatment of displaced intraarticular calcaneal fractures. However, open methods can make several complications such as neurovascular injury and infection. Thus we have performed the new technique of arthroscopic reduction and minimal internal fixation for displaced intraarticular calcaneal fractures in 5 cases. The results were evaluated between 12 and 16 months after surgery. A Bohler angle was restored to 25degrees-40degrees in all cases. Anatomical reduction of articular surface were obtained from 4 cases out of 5. No complications were found except 1 peroneal tendinitis. The clinical results by Creighton-Nebraska health foundation assessment for fractures of the calcaneus were 3 excellent, 1 good and 1 fair. Even though this was a few case and a short term follow-up study, the arthroscopic assisted management of displaced intraarticular calcaneal fracture induced a little complications and satisfactory results.

Epidermal keratinocytes are important sources of a wide variety of cytokines that include the endothelin-1 (ET-1). Glucocorticoids have been shown to inhibit the production of several cytokines. However, their effect on ET-1 synthesis by keratinocytes is still unknown. It has been reported that ultraviolet B (UVB) irradiation stimulates both the synthesis and release of ET-1 and it was observed that ET-1 secretion by HaCat cells increased with increasing UVB exposure. In this study, the effects of glucocorticoid on ET-1 production were evaluated using cultured HaCat keratinocytes. The results showed that dexamethasone suppressed basal re-lease of ET-1. In addition, it strongly inhibited the UVB-mediated augmentation of ET-1 production. Furthermore, lincomycin slightly enhanced the inhibitory effect of dexamethasone on ET-1 synthesis.

The present study was designed to elucidate the recent prevalence of the intestinal protozoa and to demonstrate the relationship on prevalence of the surveyed population with their academic career and living conditions. During the period from May to July 1981, total 2,735 fecal specimens were collected from the inhabitants of 11 areas in Gyeong-gi Do (province) near by Seoul City, and 6 areas in Jeonra Bug Do, southwestern part of Korea. The samples were fixed with SAF solution and were examined by formalin-ether sedimentation technique. The results are summarized as follows: Overall positive rate of intestinal protozoa was 11.1 percent: Gyeong-gi Do, 10.7 percent; Jeonra Bug Do, 11.7 percent. Five species of intestinal protozoa were detected: Entamoeba histolytica 0.69 percent, Entamoeba coli 5.52 percent, Endolimax nana 2.71 percent, Giardia lamblia 2.23 percent, Iodamoeba butschlii 0.l8 percent. Highest positive rates among the examined areas were recognized: Incheon City of Gyeong-gi Do, 26.7 percent; Im-sil Gun(county) of Jeonra Bug Do, 19.9 percent. By species, E. nana showed the highest prevalence rate (13.74 percent) in Incheon City, and E. histolytica (2.37 percent) and E. coli (9.95 percent) in Im-sil Gun. Prevalence of E. histolytica in rural areas was higher than in urban areas. No significant difference in the prevalence rate by sex and age was recognized, although the group under 10 years and over 60 years were lower than in other age groups. The highest positive rate of E. histolytica was observed in pauper group and significant linearity of prevalence rate of E. histolytica by monthly income was observed. The inhabitants who used conventional latrine showed higher prevalence, 11.5 percent, than the group of inhabitants who used modified privy. Although no significant difference of positive rate was recognized by academic career, but the lowest prevalence rate was observed in college graduates. Over half of the surveyed population, 64.8 percent has no experience on anthelmintic practice. Number of anthelmintic application resulted no difference in prevalence. In conclusion, prevalences of intestinal protozoa in Gyeong-gi Do and Jeonra Bug Do decreased remarkably in comparison with those of one decade before. However, economic level, academic career and anthelmintic administration seemed no essential reasons for such declination.
