We report herein a case of tuberculosis cutis orificialis in a 50-year-old man. He suffered from well demarcated, 2x5cm sized, slightly tender, pus discharging, perianal ulcer with bluish edges for 3 months. The biopsy specimen from the ulcer revealed tuberculoid structure with Langhans giant cells in the deep dermis and a few acid-fast bacilli. AFB cultures from the sputum, pus, and tissue were successful. Intradermal test with PPD showed positive result. Chest roentgenographic findings disclosed advanced pulmonary tuberculosis. Almost complete healing of the perianal ulcers occurred following 2 months of therapy using antituberculosis drugs.

We report herein a 53-year-old male patient with a large condyloma acuminaturn of 16 months duration on his penis. Clinically, an approximat;ely 3.5 X 2.0 Cm sized, asyrnptomatic, verrucous-surfaced, papilloma was present on his prepuce and glans. Elistological examination disclosed hyperkeratosis, marked acanthosis, papillomatosis, vacuolated upper malphigian cells, dilated capillaries, and mononuclear infiltrntes in the upper dermis. Trial of DNCB immunotherapy showed a dramatic effect on tumor regression.

PURPOSE: To investigate whether endogenous and exogenous female hormone exposures were associated with risks for age-related macular degeneration (AMD) in postmenopausal women. METHODS: This study included 4,479 postmenopausal females aged 45 years and older who completed the Korea National Health and Nutrition Examination Survey (KNHANES) V. The participants were divided into 4 groups: subjects with AMD, subjects without AMD, subjects with early AMD, and subjects with late AMD. Variables associated with endogenous and exogenous female hormone exposures were analyzed. RESULTS: Among the 4,479 participants, 516 were found to have AMD and 3,963 were normal. There was no significant difference between the AMD and normal groups execpt for age in the risk analysis. Of the total 516 AMD participants, 488 had early AMD and 28 had late AMD. Women with AMD who had used oral contraceptives longer in the past had significantly higher odds of late AMD than early AMD (odds ratio [OR] = 1.013, 95% confidence interval [CI]: 1.002–1.024). Increasing number of children was also associated with decreased odds of late AMD (OR = 0.672, 95% CI: 0.506-0.893). CONCLUSIONS: These findings suggest that exposure to endogenous and exogenous female hormones may influence the risk of AMD progression.

PURPOSE: To evaluate 25-gauge transconjunctival sutureless vitrectomy for primary repair of rhegmatogenous retinal detachment (RRD). METHODS: We performed a retrospective study of 46 consecutive eyes of 46 patients who underwent 25-gauge transconjunctival sutureless vitrectomy to repair primary RRD. Outcome measures included single surgery anatomical success rate, final anatomical success rate, postoperative visual acuity, and surgical complications. RESULTS: Forty eyes were phakic and six eyes were pseudophakic. Twenty-six eyes had superior quadrant retinal tear, 12 eyes had inferior quadrant tear and eight eyes had both. The mean operation time was 56.3 minutes. The single surgery anatomical success rate was 93.48% (43/46). Two eyes with recurrent retinal detachment underwent fluid gas exchange: one received barrier laser treatment in the outpatient clinic, and the other underwent reoperation; the final success rate was 100%. The best corrected visual acuity improved from 1.34 log MAR to 0.48 log MAR (p < 0.01) in macula - off patients (30 eyes) and from 0.32 log MAR to 0.07 log MAR (p = 0.279) in macula - on patients (16 eyes). Postoperative complications included wound leaking (two eyes), cataract progression (13 eyes), vitreous hemorrhage (one eye), transient hypotony (one eye), and increased intraocular pressure (seven eyes). CONCLUSIONS: Primary repair of RRD using 25-gauge transconjunctival vitrectomy resulted in an excellent final anatomical success rate and postoperative visual outcomes.

Recently, research on rectal neuroendocrine tumors (NETs) has increased during the last few decades. Rectal NETs measuring <10 mm without atypical features and confined to the submucosal layer have only 1% risk of metastasis, and the long-term survival probability of patients without metastasis at the time of diagnosis is approximately 100%. Therefore, the current guidelines suggest endoscopic resection of rectal NETs of <10 mm is regarded as a safe therapeutic option. However, there are currently no clear recommendations for technique selection for endoscopic resection. The choice of treatment modality for rectal NETs should be based on the lesion size, endoscopic characteristics, grade of differentiation, depth of vertical involvement, lymphovascular invasion, and risk of metastasis. Moreover, the complete resection rate, complications, and experience at the center should be considered. Modified endoscopic mucosal resection is the most suitable resection method for rectal NETs of <10 mm, because it is an effective and safe technique that is relatively simple and less time-consuming compared with endoscopic submucosal dissection. Endoscopic submucosal dissection should be considered when the tumor size is >10 mm, suctioning is not possible due to fibrosis in the lesion, or when the snaring for modified endoscopic mucosal resection does not work well.

BACKGROUND: Neointimal hyperplasia and thrombosis are the major factors responsible for vascular access occlusion. Previous studies suggested that the renin-angiotensin system has been implicated in the pathogenesis of neointimal hyperplasia and thrombosis. Recent studies have shown that angiotensin-converting enzyme (ACE) gene polymorphism may have a association with venous thrombosis. We conducted a retrospective case control study to determine the influence of ACE gene polymorphism on the progression of radiocephalic wrist arteriovenous fistulae (RCAVF). Also, we investigated the association between ACE polymorphism and various thrombotic factors in thrombosed and nonthrombosed subjects. METHODS: 56 patients (24 males and 32 females, mean age 49.8, age range 12-81) whose RCAVF had been maintained in good condition after 2 months of vascular access operation were included in this study. Lipoprotein (a), total cholesterol, C-reactive protein (CRP) and homocystein were measured before hemodialysis session in fasting state. Clinical data such as body mass index (BMI), cigarette smoking, hypertension, and diabetes were retrieved from patient's records. The ACE genotype was analyzed by the polymerase chain reaction (PCR). RESULTS: The incidence of diabetes and cigarette smoking were similar in the three genotypes. There were no significant differences in BMI, total cholesterol, lipoprotein (a), CRP and homocystein (p=0.551, 0.429, 0.279, 0.392, 0.124, respectively) among DD, ID and II genotypes. The percentage of the DD, ID and II genotypes were 16%, 43%, 41%, respectively. Compared with the ID and II genotypes, the proportion of the thrombosed AV shunts was larger in DD genotypes. But there was no statistically significant difference between ACE polymorphism and RCAVF thrombosis (x2=1.027, df=2, p=0.598). ACE polymorphism is shown to have no association with body mass index, blood level of total cholesterol, lipoprotein (a), CRP and homocystein. CONCLUSION: These results suggest that ACE polymorphism may have some influences on the vascular access occlusion in maintenance hemodialysis patients and have no relationship with body mass index, total cholesterol, lipoprotein (a), CRP and homocystein.
