In September 1998, a case of nosocomial cutaneous myiasis caused by Lucilia sericata (Meigen, 1826) in a 77-year-old male was found. The patient had been receiving partial maxillectomy due to the presence of malignant tumor on premaxilla. This is the first verified case involving Lucilia sericata in Taegu, Korea. In the present paper, the salient morphological features of the third instar larvae involved have been studied.

The ability of photochemotherapy(PUVA) or UVA phototherapy to stimulate melangenesis is well known. It is now recognized that the PUVA lentigines, irregular in outline and often more darkly and unevenly pigmented than solar lentigines, are related to the additional pigmentary effects of the PUVA therapy. We present herein four cases of unusual pigmentation after one month of UVB irradiation. Raticulated dark brown pigmentation appeared on the lower extremities of the patients. Histopathologicially, an increase in melanin in the basal layer was found, but no dysplasia or malignant change. We suggest UVB as the cause of this unusual hyperpigmentation.

A 23 year old female patient swallowed a tooth brush about one month prior to admission. She has been felt discomfort in epigastrium and dull aching pain recently around umbilicus. Upper gastrointestinal X-Ray and gastroduodenoscopic examination disclosed that a full size, yellow tooth brush is lodged transversely in the stomach and duodenal bulb, Endoscopic remova.l was tried and failed because of impaction of the both ends into mucosa. The tooth brush was removed by gastrotomy under general anesthesia. The free end of the brush handle penetrated the duodenal bulb wall and the impaction of the tip prevented the leakage of duodenal contents before removal. Though the primary method of the gastroduodenal foreign body is endoscopic, if sharp end of the forei body seems to be impacted into the gastrointestinal wall, and if it retained same position for long duration, it should not tried to remove by force fo prevention of leakage and resulting peritonitis. Surgical removal may be safer method in these cases.

Heterotopic panereas is pancreactie tissue occuring outside its normal anatomical location and without any connection and normal pancreas and it is a developmental anormaly. The most commen site is stomach(esp. greater curvature of the antrum), duodenum and jejunum, In majority of cases heterotopic pancreas does not produce symptoms. When it produces complications, the symptoms depend on the site of lesion and the size of mass. Pathologically, the heterotopic pancreatic tissue is subject to all the lesions found in the normally placed pancreas. Tbe smooth broad base intramural defect with central niche ie typical radiologic fiadings of heterotoPic pancreas. Gastrofiberscopy revealed a small round, submucosal projection with a central umblication. The lesions are frequently confused with polys, lymphoma, in.tramural neoplasm and gastric uleer. Accurate diagnosis may prevent needless surgical procedures. Three cases of heterotopic pancreas of stomach were reported and the pertinent literature were reviewed briefly.

We observed a 51-year-old male, who developed depigmented patches on the lower abdomen after photochemotherapy(PUVA) of psoriasis without evidence of phototoxic reaction. The depigmented patches did not orginate from the sites of previous psoriatic lesions. Fontana-Masson stain of the biopsy specimen revealed nearly absent melanin pigments in the epidrmis of the hypopigmented patch, while lots of pigments were obsereved on the surrounding hyperpigmented area. Electron micrograph showed no melanocytes in the hypopigmented patch. Thus we report this case as having vitiliginous patches induced by photochemotherapy of psoriasis.

OBJECTIVES: Depression, sleep complaints and cognitive impairments are commonly observed in the elderly. Elderly subjects with depressive symptoms have been found to show both poor cognitive performances and sleep disturbances. However, the relationship between sleep complaints and cognitive dysfunction in elderly depression is not clear. The aim of this study is to identify the association between sleep disturbances and cognitive decline in late-life depression. METHODS: A total of 282 elderly people who underwent nocturnal polysomnography in a sleep laboratory were enrolled in the study. The Korean version of the Neuropsychological Assessment Battery developed by the Consortium to Establish a Registry for Alzheimer's Disease (CERAD-K) was applied to evaluate cognitive function. Depressive symptoms were assessed with the geriatric depression scale (GDS) and subjective sleep quality was measured using the Pittsburg sleep quality index (PSQI). RESULTS: The control group (GDS< or =9) when compared with mild (10< or =GDS< or =16) and severe (17< or =GDS) depression groups, had significantly different scores in the Trail making test part B (TMT-B), Benton visual retention test part A (BVRT-A), and Stroop color and word test (SCWT)(all tests p<0.05). The PSQI score, REM sleep duration, apnea-hypopnea index and oxygen desaturation index were significantly different across the three groups (all indices, p<0.05). A stepwise multiple regression model showed that educational level, age and GDS score were predictive for both TMT-B time (adjusted R2=35.6%, p<0.001) and BVRT-A score (adjusted R2=28.3%, p<0.001). SCWT score was predicted by educational level, age, apnea-hypopnea index (AHI) and GDS score (adjusted R2=20.6%, p<0.001). Poor sleep quality and sleep structure alterations observed in depression did not have any significant effects on cognitive deterioration. CONCLUSION: Older adults with depressive symptoms showed mild sleep alterations and poor cognitive performances. However, we found no association between sleep disturbances (except sleep apnea) and cognitive difficulties in elderly subjects with depressive symptoms. It is possible that the impact of sleep disruptions on cognitive abilities was hindered by the confounding effect of age, education and depressive symptoms.

A 31-year-old male patient had malignant atrophic papulosis that afected the skin only. He had multiple typical porcelain-white skin lesion on the face and trunk without abdominal symptoms. Histopathologic studies showed moderate inflammatory infiltration in addition to the typical cone-shaped region of necrobiosis, There are no satisfactory treatment modes, and in the present case, the patient's condition improved transiently on oral medication of aspirin, but we lost the contact with him afterwards.

Thombolytic therapy and placement of vascular metallic stent can be used for the treatment of lilac venous stenosis and thrombosis, but these treatments increase the risk of pulmonary thromboembolism. Inferior vena cava filter was developed for the prevention of recurrent pulmonary thromboembolism due to lower extremity deep vein thrmobosis and has been regarded as relatively safe and effective treatment modality. We experienced good result of combined treatment of inferior vena filter, thrombolytic therapy and placement of right lilac venous metallic stent in a patient with severe stenosis and thrombosis at both common lilac veins.

The thickness of the glomerular basement membrane may vary not only in glomerular disease, but also in normal persons according to age and sex. But there has been no data on the normal thickness of the basement membrane in Korea. This study was designed to determine the glomerular basement membrane thickness as a reference value according to age and sex, in 50 cases of minimal change disease obtained from patients aged 2~67 years. Measurement of glomerular basement membrane was made on electron micrograph using an image analyzer. The thickness of each case was estimated by the arithmetic and harmonic mean methods. The mean thickness of the glomerular basement membrane was 291.9 47.9 nm by harmonic mean method and 284.2 43.7 nm by arithmetic mean method. And the harmonic mean thickness of the glomerular basement membrane according to age was 249.1 32.5 nm (1~5 years), 256.6 45.3 nm (6~10 years), 279.2 57.9 nm (11~15 years), 303.2 43.8 nm (16~20 years), 335.3 37.5 nm (21~30 years), and 291.1 22.5 nm (over 30 years), respectively. There was a trend that the thickness of glomerular basement membranes increased with the age till 30 years of age. There was no significant sex-related difference. In conclusion, the mean glomerular basement membrane thickness is comparable to the data from western people and shows a trend of increasing thickness according to the age.
