Fournier's gangrene is a fulminating gangrene of the male genitalia. It is associated with severe systemic toxic effect and a high motality rate, and it requires early diagnosis and intensive care with surgical intervention. We report a case of Fournier's gangrene in 33-year-old man, who showed marked swelling and necrosis of the scrotum, and extending cellulitis on the right flank and chest. With prompt excision of all the gangrenous scrotal skin and drainage incisions made on the flank and chest, the healing was successful.

A 18-month-old girl was seen because of an yellowish brown papular eruptions on the face, earlobes and neck of one year duration. A skin biopsy specimen revealed circumscribed cellular infiltrates composed of predorninantly pleornorphic histiocytes. Electron microscopy of biopsy material disclosed numerous worm like particles and coated vescles in limited area of the cell cytoplasm, consistent with the findinga described in benign cephalic histiocytosis. After six months of her first visit, the individual papules became flattened.

OBJECTIVES: The dopamine-blocking effects and the associated side effects(amenorrhea, lactation, sexual dysfunct of classical antipsychotics in schizophrenic patients have been studied for a long time. The purpose of this study to find out these effects of new antipsychotics(risperidone, olanzapine) in schizophrenic patients treated with clinical relevant doses. METHOD: Plasma levels of both prolactin and testosterone were measured in 91 schizophrenic patients(28 taking haloperidol, 4-20mg/day ; 31 taking risperidone, 2-6mg/day/ 32 taking olanzapine, 5-20mg/day). RESULTS: In male schizophrenic patients, the prolactin levels of risperidone group(76.44+/-38.85ng/ml) and haloperidol group(60.26+/-20.74ng/ml) had no significant difference, but were significantly higher than that of olanzapine(26.90+/-5.36ng/ml). In female, the prolactin level of olanzapine group(36.66+/-17.55) was significantly lower than those of risperidone(121.7+/-.33) and haloperidol group(161.66+/-37.53). And prolactin level of risperdone group was lower than that of haloperidol group. While the testosterone plasma level of risperidone, haloperidol and olanzapine in both male and female schizophrenic patients had no significant difference. CONCLUSIONS: At doses known to be effective in popular clinical setting, prolactin level in patients taking risperidone we higher than that of haloperidol, while olanzapine showed no significant difference in terms of prolactin plasma level haloperidol. New antipsychotics may not influence the testosterone plasma level.

Purpose:
To investigate the surgical outcomes of endonasal dacryocystorhinostomy with canalicular trephination in patients with canalicular obstruction.
Methods:
We retrospectively analyzed the medical records of 37 eyes from 32 patients who were diagnosed with canalicular obstruction between May 2010 and July 2022 and underwent endonasal dacryocystorhinostomy with canalicular trephination to evaluate the success rate and complications.
Results:
In the total patient group, 81.1% achieved complete success in which epiphora completely disappeared, 13.5% had partial success in which epiphora remained but improved, and 5.4% experienced failure in which tearing persisted or worsened. Complications included one case of dacryocystorhinostomy bony opening granuloma and one case of dacryocystorhinostomy bony opening inflammation.
Conclusions
Endonasal dacryocystorhinosomy with canalicular trephination is an effective method for treating canalicular obstruction, offering a high success rate and few complications. It can be considered before resorting to conjunctivodacryocystorhinostomy, which is a more conventional treatment.

Chios gum mastic (CGM) is produced from Pistiacia lentiscus L var chia, which grows only on Chios Island in Greece. CGM is a kind of resin extracted from the stem and leaves, has been used for many centuries in many Mediterranean countries as a dietary supplement and folk medicine for stomach and duodenal ulcers. CGM is known to induce cell cycle arrest and apoptosis in some cancer cells. This study was undertaken to investigate the alteration of the cell cycle and induction of apoptosis following CGM treatment of HL-60 cells. The viability of the HL-60 cells was assessed using the MTT assay. Hoechst staining and DNA electrophoresis were employed to detect HL-60 cells undergoing apoptosis. Western blotting, immunocytochemistry, confocal microscopy, FACScan flow cytometry, MMP activity and proteasome activity analyses were also employed. CGM treatment of HL-60 cells was found to result in a dose- and time-dependent decrease in cell viability and apoptotic cell death. Tested HL-60 cells showed a variety of apoptotic manifestations and induced the downregulation of G1 cell cycle-related proteins. Taken collectively, our present findings demonstrate that CGM strongly induces G1 cell cycle arrest via the modulation of cell cycle-related proteins, and also apoptosis via proteasome, mitochondrial and caspase cascades in HL-60 cells. Hence, we provide evidence that a natural product, CGM could be considered as a novel therapeutic for human leukemia.

OBJECTIVE: To compare the differences of hormone replacement therapy (HRT) and reproductive, life style characteristics in postmenopausal women with and without rheumatoid arthritis (RA). METHODS: A total of 360 women, 120 rheumatoid arthritis patients and 240 age matched healthy women were randomly selected from the health care center. Subjects were labeled as rheumatoid arthritis and normal menopausal women. Each group was compared for their HRT status, life style and reproductive characteristics. RESULTS: There were significantly less HRT received subjects in RA group (50.0% vs 76.1%, respectively, OR=0.30, p<0.05). More frequently alcohol consumed in RA group (26.7% vs 11.7%, respectively, p<0.05). There was no significant difference in the history of hysterectomy and smoking as well as body mass index (BMI) between the two groups. Women with serum follicular stimulating hormone (FSH) over 40 IU/L were more frequently observed in RA group (70.0% vs 57.5%, respectively, OR=1.75, p<0.05). CONCLUSION: Increased FSH and history of alcohol drinking were more frequently observed in patients with RA, whereas history of HRT was lower in RA group comparing to that of the control. A prospective study should be designed to confirim the protective effect of HRT and reproductive characteristics on postmenopausal RA patients.

PURPOSE: This study was performed to evaluate the expressions of osteopontin (OPN) and clusterin in a transitional cell carcinoma (TCC) of the urinary bladder, and then compare their expression rates with the tumor invasiveness. MATERIALS AND METHODS: Twenty-five superficial and 25 invasive TCC were used for immunohistochemical staining. RESULTS: All 25 non-invasive TCC showed a strong positive reaction for OPN. Twenty of the invasive TCC showed a strong positive reaction for OPN, but 5 showed only a weak positive reaction. OPN expression was significantly decreased in the invasive TCC (p=0.02). Eighteen superficial TCC showed a weak positive reaction for clusterin, with 7 showing a negative reaction. Nine invasive TCC showed a strong positive reaction for clusterin, and 11 showed only a weak positive reaction. Five invasive TCC showed a negative reaction for clusterin. Clusterin expression was significantly increased in the invasive TCC (p=0.001). CONCLUSIONS: These results may suggest that OPN and clusterin could be used as markers to predict the biological behavior of a TCC.

BACKGROUND: Paresthesia is unpleasant for patients and more importantly, is related to neurological injury in some cases. There have been few studies comparing combined spinal-epidural anesthesia (CSE) techniques such as needle-through-needle technique (NTN) and double segment technique (DST) regarding the incidence of paresthesia. METHODS: Eighty-four parturients undergoing CSE for an elective cesarean section were divided into NTN and DST groups. A CSE was performed using 27 G Sprotte needle, 18 G Tuohy needle and 20 G multiport catheter in both groups. In the NTN group, at L3-4 or L4-5, a spinal anesthesia was performed and then an epidural catheter was inserted through the same Tuohy needle. In the DST group, an epidural catheter was inserted at L1-2 or L2-3 and then a spinal anesthesia was done two interspaces caudally. Incidences of paresthesia with each procedure were recorded with block characteristics and adverse effects. RESULTS: Overall frequency of paresthesia was higher in the NTN group (54.8% vs. 29.3%, P = 0.033). Incidences of intrathecal paresthesia were three times higher (21.4% vs. 7.3%, not significant) and epidural paresthesia was significantly higher (45.2% vs. 22%, P = 0.044) in the NTN group. Sensory and motor block characteristics and side effects were mostly comparable between the groups. CONCLUSIONS: Double-segment technique shows less incidence of overall paresthesia compared to needle-through-needle.
