PURPOSE: Finasteride is an inhibitor of human 5alpha-reductase, which results in a decrease in plasma and intraprostatic dihydrotestosterone(DHT) level. We investigated the changes of prostate volume(PV), transitional zone volume(TV), and PSA during and after administration of finasteride. MATERIALS AND METHODS: From 1995, 32 BPH patients treated with finasteride underwent surveillance after cessation of finasteride. Surveillance included measurements of PV, TV and PSA every 3 to 6 months. The mean age of the patients was 66.7 years(57-73). The mean duration of treatment and cessation were 8.6 months(6-12) and 8.0 months(6-12), respectively. The changes in PV, TV, and PSA were compared. RESULTS: The mean initial PV, TV, PSA were 45.7cc, 22.5cc, 2.72ng/ml, respectively. After treatment, PV, TV, PSA were reduced to 72.7%, 67.1%, 64.7% and 68.0%, 61.4%, 57.3% and 59.4%, 55.0%, 52.5% of the original values at 3, 6 and 12 months, respectively. The reduction rate was maximum after the first 3 months(p=0.001). After discontinuing finasteride, PV, TV, PSA recovered to 71.0%, 71.2% 63.9% and 84.0%, 82.3%, 67.6% and 90.4%, 85.1%, 74.1% at 3, 6 and 12 months, respectively. The recovery rates of PV and TV after 3 and 6 months were equal. However, recovery rate of PSA was maximum at 3 months and after then, constant until 12 months. CONCLUSIONS: During first 3 months` treatment, the decreasing rates of PV, TV and PSA were very considerable, after then, reduced. After cessation of medication the recovery rates of PV, TV were constant during first 6 months but PSA was maximum at first 3 months. The changes in clinical parameters during administration were fully recovered but it took slightly longer periods after cessation compared to those during of treatment. PSA is probably a predictor in the assessment of volume changes.

Acute cerebral infarctions are rare in children, however, they can occur as a complication of a Mycoplasma pneumoniae (MP) infection due to direct invasion, vasculitis, or a hypercoagulable state. We report on the case of a 5-year-old boy who had an extensive stroke in multiple cerebrovascular territories 10 days after the diagnosis of MP infection. Based on the suspicion that the cerebral infarction was associated with a macrolide-resistant MP infection, the patient was treated with levofloxacin, methyl-prednisolone, intravenous immunoglobulin, and enoxaparin. Despite this medical management, cerebral vascular narrowing progressed and a decompressive craniectomy became necessary for the patient's survival. According to laboratory tests, brain magnetic resonance imaging, and clinical manifestations, the cerebral infarction in this case appeared to be due to the combined effects of hypercoagulability and cytokineinduced vascular inflammation.

Impetigo herpetiformis is a form of pustular psoriasis that occurs during pregnancy and may be life-threatening. The pathogenesis and etiology of impetigo herpetiformis is not clear, but several reports have associated onset of this disorder with hypocalcemia, hypoparathyroidism, and the use of oral contraceptives. The typical lesions are erythematous patches that are studded with tiny superficial pustules particularly coalescing at their margins causing pain, and a burning sensation. Laboratory findings include an elevated erythrocyte sedimentation rate, increased peripheral blood leukocyte counts, hypoalbuminemia, and in severe cases, hypocalcemia. The histopathology is the same as that of pustula psoriasis. Our patient, a 31 year-old female (Intra Uterine Pregnancy 28 weeks), was admitted to our hospital due to generalized skin eruption and severe constitutional symptoms. Her clinical features, laboratory and histopathologic findings were compatible with that of impetigo herpetiformis. In spite of our all efforts, intrauterine fetal death was noted at her 33rd week of pregnancy. We report a case of impetigo herpetiformis terminating in fetal death with the review of literature.

PURPOSE: The goal of intermittent androgen deprivation (IAD) therapy in prostate cancer patients is to delay the disease progression and improve the survival rate. Therefore, the duration of off-treatment is very important for the effective treatment outcome of IAD. We analyzed factors that influence the duration of off-treatment in IAD. MATERIALS AND METHODS: We reviewed the medical records of 45 patients with prostate cancer who had completed at least 1 cycle of IAD. Uni- and multi-variate tests were used to determine the factors, which are predictive to the duration of off-treatment. These factors included: the patient's age, biopsy Gleasons score, initial PSA, presence of bone metastasis, PSA levels at 3 months following on-treatment and at 3 months following off-treatment, and the duration of on-treatment. RESULTS: The average follow up duration was 34 months (15-71 months). The average off-treatment duration of each cycle was 11.1 (4-40), 7.5 (4-14), and 5.6 (3-10) months for the 1st, 2nd and 3rd cycles, respectively. Independent factors associated with the extension of duration of off-treatment, by univariate tests, included: initial PSA value, PSA values at 3 months following on-treatment, PSA at 3 months following off- treatment, and duration of on-treatment. The duration of off-treatment was inversely related to the serum PSA level at the start, 3 months following on-treatment, and 3 months following off-treatment, while it was directly related to the duration of on- treatment by multivariate tests. CONCLUSIONS: The pretreatment serum PSA level and the serum PSA level at 3 months following on-treatment and off-treatment were valuable predictors for the duration of off-treatment in IAD.

PURPOSE: Cyclin D1 plays critical roles in the progression of cells through the G1 phase of the cell cycle, which has been implicated as a putative protooncogene, while p53 protein affects different phase checkpoint pathways in the normal cell cycle, which mutations occur in poor prognosis of cancer. We attempted to determine their significance for tumor behavior and prognosis of transitional cell carcinoma(TCCa) of the bladder in human. MATERIALS AND METHODS: Formalin fixed-paraffin embedded tissue specimens from 102 patients with TCCa of the urinary bladder were examined. Nuclear expression was detected by immunohistochemical analysis with a standard avidin-biotin immunoperoxidase method, using the monoclonal antibody cyclin D1 and p53(DO7). RESULTS: Cyclin D1 and p53 protein immunostaining of the nucleus was observed in 49 tumors(48.0%) and 55 tumors(53.9%) respectively. Overexpression of cyclin D1 showed significant inverse correlation with the histological grade and significant correlation with recurrence. Overexpression of p53 protein showed a significant correlation with the histological grade and stage(p<0.01). 65.3% (32 out of 49 tumors), of the cyclin D1 positive tumors exhibited expression for p53 protein(p<0.05). Patients with TCCa coexpressing cyclin D1 and p53 protein had a significantly poorer prognosis than those expressing neither cyclin D1 nor p53 protein(p<0.001). CONCLUSIONS: Cyclin D1 in bladder TCCa is closely related to early tumor differentiation and associated with recurrence. Simultaneous overexpression of both cyclin D1 and p53 protein is related to more aggressive tumor behavior and poorer prognosis. This indicates that cyclin D1 evaluation may be a further useful element for selecting subgroup of patients who should be treated with more aggressive therapies.

BACKGROUND: Erythema multiforme is an inflammatory disorder of the skin which may be characterized by erythematous papules, plaques, vesicles, and 'target-like' annular lesions. Mucosal lesions may occur. Symmetric irivolvement of the extrernities, especially the dorsurn of the hands and feet, and face is the classic pattern of cutaneous distribution. Palmoplantar lesions of erythema multiforme are relatively uricornmon. OBJECTIVE: Our purpose was to investigate the clinical and histopathological characteristics of erythema multiforme involving the palm and sole. METHODS: Thirty one cases of erythema multiforme involving the palm and sole, and thirty cases involving other sites wer collected and analysed with particular reference to epidemiological data, type and distribution of the skin lesion and histopathological characteristics. RESULTS: 1. The median ages of both groups were the early thirties. There were no sexual predominances. 2. The clinical features of erythema multiforme involving the palm and sole were relatively mild and showed atypical skin lesions including macules and papules compared with erythema multiforme involving the other sites. 3. The histopathological changes of the palmoplantar group were also mild, especially the epidermal changes which included keratinocytes necrosis, subepidermal blisters, focal parakeratosis, extensive epidermal necrosis and xocytosis etc. 4. The most important and consistent histopathological finding of the palmoplantar erythema multiforme group was lymphocyte tagging along the basernent membrane, which was found consistently apart from one case. CONCLUSION: We investigated the clinical and histopathological features of erythema multiforme involving the palm and sole. They showed mild clinical features and atypical skin lesions cornpared with other group. The histopathological spectrum of this group was diverse, and reflected the early stage of pathomecha nisms of erythema multiforme. Among them, lyrnphocyte tagging was the most important and censistent finding in palmoplantar erythema multiforme.

Bipotent progenitors for T and natural killer (NK) lymphocytes are thought to exist among early precursor thymocytes or liver lymphocytes. The identification of such a progenitor population or mature NK cells in such organs remains undefined. Here we report the identification of a novel receptor of NK cells, p58 (HLA class I-specific inhibitory receptors), in fetal thymocytes and fetal liver lymphocytes. Our finding suggests the NK cells mature in the developmental stage during feta1 ontogeny. Flow cytometric analysis revealed p58 positive cells in thymocytes or in fetal liver lymphocytes and reverse transcription PCR also showed amplification of p58 RNA. The result of single stranded conformational polymorphism (SSCP) showed it discriminates one or two base pair differences of the p58 gene. Although the question still remains as to whether the expression of p58 is due to the NK cells or natural T cells, it is clear the p58 is expressed in fetal thymocytes or liver lymphocytes. And SSCP analysis using appropriate sets of primers used in this study, is helpful to study the diversity of p58.

Mixed squamous cell carcinoma and papillary carcinoma in the thyroid gland is a very rare malignant tumor characterized by rapidly progressive clinical course and radioresistance. A 63-year-oid woman had mixed squamous cell carcinoma and papillary carcinoma in the thyroid gland diagnosed by fine needle aspiration cytology (FNA), and the diagnosis was confirmed by histological examination. She had complained of a fixed, egg-sized mass of the anterior neck with hoarseness for 1 year. The findings of FNA consisted of sheets and clusters of polygonal epithelial cells with hyperchromatic, pleomorphic nuclei and eosinophilic, abundant, laminated cytoplasm. These findings were consistent with squamous cell carcinoma. Also, foci of papillary carcinoma were noted, and the cells exhibited nuclear groovings and intranuclear cytoplasmic inclusions. Total thyroidectomy specimen showed a diffusely infiltrating tumor in the left thyroid which was composed of mixed papillary carcinoma and well-differentiated squamous cell carcinoma. In junction between two components, squamous metaplasia of papillary carcinoma was noted.

The most common cause of obstructive sleep apnea syndrome (OSAS) in childhood is adenotonsillar hypertrophy. Adenotonsillectomy improves the symptoms quite well in most cases. However, some patients could experience the OSAS again after adenotonsillectomy, who might have several risk factors such as incomplete operation, misdiagnosis, combined anatomical malformation, sinusitis or chronic allergic rhinitis, obesity, initial severe OSAS, and early onset OSAS. We report a case of 11-year-old obese boy who presented with snoring for several years. He was obese with body mass index (BMI) of 26.3 kg/m2 and also found to have fatty liver by ultrasonogram. Initial polysomnography (PSG) showed that he met the criteria of severe OSAS with the apnea-hypopnea index (AHI) of 70.5. He underwent adenotonsillectomy and symptoms improved immediately. Four months later symptoms were relieved with AHI of 0, but 1 year after the adenotonsillectomy he started to complain snoring again and the subsequent PSG results showed that OSAS has relapsed with AHI of 43. Paranasal sinus X-ray and physical examination showed sinusitis and re-growth of adenoid. Obesity was proved not to be a contributing factor because his BMI decreased to normal range (23.1 kg/m2) after diet control and regular exercise. Also, liver transaminase was normalized and fatty liver was disappeared on follow-up abdominal ultrasonogram. After treatment of sinusitis, symptoms were relieved with decreased AHI (8.5). This case suggests that simple adenotonsillectomy might not be the end of OSAS treatment in childhood. Patients who had adenotonsillectomy should be followed by subsequent PSG if symptoms recur. It is also important to be aware of risk factors in the recurrent OSAS for the proper intervention according to the cause.
