PURPOSE: We studied the crystallographic component of the prostatic calculi according to the location on the transrectal prostatic ultrasonography to know the mechanism of the formation of the calculus. MATERIALS AND METHODS: From August, 1995 until May, 1997, 33 prostatic calculi from 24 patients(mean age 59 years, mean size 3.1mm) operated on for prostatism were analyzed by polarization microscopy(ZeissR), X-ray diffraction(PW-1720R, Philips) and infrared spectrophotometer(FTIR-205R, Nicolet). Location of calculi was divided two groups under guide of transrectal prostatic ultrasonography; periurethral and periadenoma type. The periurethral type showed hyperechoic density around the prostatic urethra and the periadenoma type showed hyperechoic density between adenoma and false prostatic capsule(peripheral zone). RESULTS: 22 calculi were the periurethral type and 11 were periadenoma type. Thirty stones from 20 periurethral type and 10 periadenoma type consisted two or three of the following calcium phospate, calcium oxalate and tricalcium phospate. These are mixed by the endogenous origin formed from the prostatic fluid and the exogenous origin formed at least in part from urine. Three stones (2 calcium oxalate, 1 uric acid) contained only one compound which participitate from urine. All of 11 calculi of the pericapsular type had an oxalate component. CONCLUSIONS: The calculi around the periadenoma region may be formed from not only endogenous component(calcium apatite stone) but also exogenous component(calcium oxalate) or intraductal precipitation of oxalate component which has never found in the prostatic fluid. These results may suggest the necessity of reevaluation about oxalate component within the prostatic fluid.

We present a case of severe intracranial hypotension syndrome following lumbar drainage. A 60-year-old woman developed recurrent attacks of vertigo, nausea and vomiting a week prior to admission. Brain MRI revealed a homogeneously well-enhanced mass in the right frontal lobe ; this was found to be a meningioma, and was totally removed. Dural defect was covered with fat and fascia, and postoperative cerebrospinal fluid(CSF) leakage through the frontal sinus was noted. Lumbar drainage was initiated, and about 36 hours later, the patient complained of bouts of headache, nausea and vomiting. Her mental state then gradually deteriorated, and she became stuporous. Brain CT was performed immediately and revealed bifrontal subdural fluid collection and signs of severe brain edema including obliteration of ventricles and basal cisterns. The lumbar drain was then clamped and she regained consciousness 12 hours later. This case clearly demonstrates that to avoid complications such as severe intracranial hypotension syndrome in a patient who has undergone lumbar drainage, the rate and amount of CSF drainage should be closely monitored.

Sebaceous trichofolliculoma, which is a variant of trichofolliculoma, is a rare disease that clinically show a centrally depressed lesion usually singly on the nose, and histologically a centrally located cavity, lined by squamous epithelium, with numerous sebaceous lobules connected to them. We describe a case of sebaceous trichofolliculoma in a 27-year-old woman who had several brown papules on the nose. We think that this is the first report of sebaceous trichofolliculloma in Korean literature.

Intensive care unit (ICU) is an area which promotes feeling of high anxiety. And patients in ICU suffered from physical and psychological discomforts. These physical and psychological discomforts are varied according to patients themselves, age, character, illness and environment such as ICU structure, staff, operating system. Physical and psychological discomforts can affect treatment and prognosis of disease. Several reports have appeared of adverse psychological and psychiatric effects of intensive therapy. On the other hand, some patients may be reassuered by continuous surveillance and exhibit emotional reactions and increased cathecholamine production on returning to a general ward". It may be possible to have considerable influence on these effects by improving the environmental factors. We evaluated the recall of 300 patients after ICU discharge, and 609o of the patients had unpleasant experiences in ICU admission. The most frequently reported unpleasant experiences were pain(18.6%), family worries(15.6%), tracheal suction(5.0%), blood sampling(5.0%), sleep deprivation(4.6%), noise(3.3%), limit of motion and posture (3.0%), unkindness(2.6%) and others(1.0%). We asked about fear for dying in their ICU stay, and 106(35.3%) of 300 patients responded yes. There was no difference in APACHEII score between fear for death and not. Therefore we must try to reduce patient's various painful stimli by more careful and kind treatments. Medical staff should remember that their trivial behavior could stimulate patients and should try to control their patients by heartful experiencing about the prognosis.

Epidermolysis bullosa acquisita (EBA) is an uncommon autoimmune subepidermal blistering disorder and has four clinical subtypes. Among the four types of EBA, the cicatricial pemphigoid-like type is rarer than the other types and clinically the worst one. We experienced a case of cicatricial pemphigoid-like type of EBA in a 69-year-old woman, whose initial symptom was painful erosive lesions of oral mucous membrane before development of ocular and bullous cutaneous lesions. The clinical, histopathological findings and immunoblot assay were all typical of the disease. The course of her disease showed remissions by treatments including corticosteroid and intravenous immunoglobulin, but each time with exacerbations.

BACKGROUND: In patients with mitral stenosis, the degree of pulmonary hypertension is expected to be related to the severity of mitral valve obstruction. However, some patients with severe mitral stenosis do not develop reactive pulmonary hypertension. MATERIALS AND METHODS: We evaluated 34 patients with symptomatic mitral stenosis undergoing percutaneous mitral valvuloplasty by clinical, echocardiographic, and invasive hemodynamic(cardiac cathrterization) data. Prevalvuloplasty data were available in 34 subjects[mean age 38+/-9 year ; women 74% ; NYHA class 1 (6 patients), class 2 (17 patients), class 3 (7 patients), class 4 (4 patients) ; in electrocardiography, NSR(23 patients), Atrial fibrillation(11 patients)]. RESULTS: 1) The pulmonary vascular bed gradient was significantly correlated with pulmonary vascular resistance(r=0.91), mean pulmonary artery pressure(r=0.82), transmitral mean pressure gradient(r=0.64) and mitral valve area(r=-0.48). The pulmonary vascular resistance was significantly correlated with mena pulmonary artery pressure(r=0.77), transmiral mean pressure gradient(r=0.61) and mitral valve area(r=-0.54), NYHA functional classification(r=0.36). However, the pulmonary vascular bed gradient and pulmonary vascular resistance was not significantly correlated with age, sex, cardiac output, the severity of mitral regurgitation and mean left atrial pressure. 2) The mean pulmonary artery pressure was significantly correlated with mean left atrial pressure(r=0.80), transmitral mean pressure gradient(r=0.72) and mitral valve area(r=-0.47). 3) When patients were divided into those with a pulmonary vascular bed gradient > 12mmHg and = 12mmHg, the two groups were significantly different for many of these measures-Pulmonary vascular resistance(p=0.004), mean pulmonary artery pressure(p=/p<0.0001), transmitral mean pressure gradient(p=0.008), mitral valve area(p=0.04). 4) The mean left atrial pressure was significantly correlated with mean pulmonary artery pressure but not with pulmonary vascular resistance and pulmonary vascular bed gradient as the index of reactive pulmonary hypertension. 5) Results of multiple regressin analysis of factors affecting pulmonary vascular bed gradient showed that transmitral mean pressure gradient was the most significant factor(op<0.0001). 6) The decrease in mean pulmonary artery pressure from immediate before to immediate after balloon commissurotomy was related to pulmonary vascular resistance(r=0.51), pulmonary vascular bed gradient(r=0.63), mean left atrial pressure(r=0.60), transmitral mean pressure gradient(r=0.50), mitral valve area(r--0.41). CONCLUSION: In patients with mitral stensis, the degree of reactive pulmonary hypertension was significantly related to the severity of mitral stenosis(transmitral mean pressure gradient, mitral valve area) but not to mean left artial pressure. In some patients the degree of mitral stenosis could not expect the development of reactive pulmonary hypertension. It is suggested that specific predictors of pulmonary hypertension on an individual patient cannot be identified based solely on the severity of mitral valve disease and must include many factors associated with pulmonary parenchymal diseases, other heart diseases, and duration of mitral stensis.

Arytenoid cartilage displacement (dislocation and subluxation) following endotracheal intubation is a rare event. Recognition of its occurrence and subsequent treatment are important to prevent longterm consequences. A 44-year-old healthy woman was admitted for total thyroidectomy and isthmusectomy. Anesthesia was induced and a number 7 cuffed endotracheal tube with a stylet was inserted under direct vision after two unsuccessful attempts without a stylet. The trachea was extubated without any difficulty in the recovery room after the surgery. About 8 hours later, the patient complained odynophagea, dysphagea, dysphonia and hoarseness. Indirect laryngoscopy and videolaryngotelescopy at the otolaryngology department revealed anterior subluxation of both cricoarytenoid cartilages with poor mobility and edema on the vocal cords. A follow-up indirect laryngoscopic examination performed after 5 days of conservative trearment showed return of the voice quality with slightly reduced mobility on the left vocal cord.

PURPOSE: Malignant peripheral nerve sheath tumor without neurofibromatosis type 1 is very rare neoplasm. Development in the superficial soft tissue is exremely rare. Authors experienced one rare case of primary malignant peripheral nerve sheath tumor developed on abdomen. The clinical and histologic findings were described. METHODS: An 83-year-old man visited hospital with an 11x6.5x4.5 cm sized ulcerated and hemorrhagic mass on abdomen. The tumor was localized in abdominal skin and started growing 3 years ago. RESULTS: Wide excision with safety margin of 2cm and limberg flap was done. The postoperative biopsy revealed a malignant peripheral nerve sheath tumor. There was no evidence of recurrence of tumor for 16 months. CONCLUSION: Malignant peripheral nerve sheath tumor is an aggressive malignant tumor. An abrupt enlargement of size, ulceration and bleeding are suggestive of malignant chnages of the tumor. We recommand early wide excision with enough safety margin as treatment of malignant peripheral nerve sheath tumor.
