Tangential vitreoretinal traction around fovea is known to be the principal cause in the pathogenesis of idiopathic macular holes. According to the recent study, the internal limiting membrane(ILM) may provide a scaffold for fibroblast proliferation and contraction, therefore play an important role in the enlargement of macular hole. We removed the ILM during macular hole surgery and assessed the anatomical and functional outcome of the macular hole surgery. Twelve consecutive patients with full-thickness macular hole were enrolled in this study. They were examed for best-corrected vision, fundus photography, fluorescein angiography, Humphrey automated perimetry, focal eletroretinogram, before and after surgery. After surgery, vision was improved in 8 eyes(67%), hole was closed in 10 eyes(83%). Macular thresholds on visual field was increased in 8 eyes and peripheral scotomas developed in 3 eyes postoperatively. The amplitude increased in 7 eyes and the implicit time decreased in 8 eyes on focal electroretinograms postoperatively. Out results suggested that the complete removal of ILM should be attempted to improve vision and to close holes during the full-thickness macular hole surgery.

BACKGROUND: Previous studies have suggested that pityrosporurr yeasts, normal resident flora of skin, may be important in the pathogenesis of dandruff seborrheic dermatitis and confluent and reticulated papillomatosis. OBJECTIVE: We investigated the incidence and distribution of pityiosorum yeasts on clinically normal skin as a more reasonable method for providing the basic data or proving the relationship of pityrosporum and pathogenesi, of the diseases. MEHTODS: A total of 350 subjects were studied. Skin scrapings were stained with 20% Parker ink-KOH(P-KOH) solution. The numbers of pityrosporum spores and hyphe per high power field( x 400) were counted and designated according to a new grading method using bacterial index(BI) of lepra bacilli. RESULTS: The incidence rates of pityrosporum orbiculare(p. orbiculare) and pityrosporum ovale(p. ovale) were 60-70% and 20-50% of subjects respectively on seborrheic area., The incidence of p. orbicilare was highter than that of p. ovale on all examined sites except for the iterior scalp. And pityrosporal hyphae was present on anteriand posterior scalp and earwax in 24-25% of subjects respectively. The incidence of pityrosporum was higher in summer than other seasons The incidence rate of p. orbiculare and hyphae in the group aged below 9 (except neonates) and above 60, were lower than that of other age groups. The inciderice rates and distribution of grades of pityrosporum of neonates were lower than those of older subjects. CONCLUSION: The results of this study showed that the incidence and distribution of pityrosporum spores were similar to previoureports and hyphal forms were found 25% approximately on clinically normal skin of the scalp and carwax. The significance of the presenet of pityosporal hyphae and the relationship between normal skin and pityrosporal hyphae are to be firther elucidated.

Acrodermatitis continua (AC) of Hallopeau is one of the chronic relapsing pustular eruptions of the extremities. Generalization of AC sometimes occurred spontaneously, or induced by withdrawl of drugs such as corticosteroid, or pregnancy. We report a case of generalized AC in a 50-year-old woman who has been treated intermittently with various medications other than systemic retinoids. The histopathologic findings of the pustules on the fingertips and trunk revealed subcomeal abscesses and/or spongiform pustules. The patient was treated with etretinate in the dose of 50mg/day, and UVB exposure. Two months after treatment, skin lesions were markedly improved.

We report a case of Mycobacterium(M.) fortuitum infection in a 65-year-old female who presented with erythematous to purplish colored tender nodules and plaques with curst and purulent discharge on both upper and lower extremities along the sites of acupuncture. The culture of surgically excised specimen in 3% Ogawa media yielded slightly yellowish colored colonies within 2 days. Several tests for identification of the species were performed and growth on 5% NaCl, negative niacin test, positive results in nitrate reduction, catalase, urease and iron uptake tests were noted. Excision of the lesions followed by administration of minocycline and ciprofloxacin showed no sign of relapse to data a year after treatment.

PURPOSE: Transobturator slings have become an alternative to retropubic slings for the surgical treatment of stress urinary incontinence (SUI). We aimed to compare the efficacy and outcome between transobturator and retropubic mid-urethral sling procedures. MATERIALS AND METHODS: We reviewed the chart of 186 consecutive women who had sling procedures with a follow-up of at least 1 year from 2001 to 2006. The retropubic sling procedure was perfomed on 76 women assigned to retropubic group. A total 110 women received transobturator slings assingned to transobturator group. The preoperative evaluations, the indices of voiding, and postoperative complications were analysed by Student's t-test and chi-square. RESULTS: Two groups were similar in their preoperative characteristics and the perioperative parameters except the period of hospitalization and operative time. There were significant difference between the 2 groups in terms of the postoperative obstructive and iatrogenic complications. Transobturator group had shorter hospitalization and operative time and lower complications than retropubic group. CONCLUSIONS: Because transobturator sling procedures showed better results and less complications than retropubic slings, it is a safe and efficient surgical treatment for female SUI.

There has been no literature that reports a case of sino-nasal malignancy associated with polyurethane implants. However, several previous in vitro and animal model studies revealed that polyurethane implants may cause malignancy in body tissue. In this report, we describe a case of maxillary sinus spindle cell sarcoma diagnosed in a 59-year-old man who had undergone polyurethane nasal packing in the nasal cavity following endoscopic sinus surgery two years ago. Complete removal of the packing material was not confirmed as the patient has not returned for postoperative care. Although there are no direct evidence of association between this spindle cell sarcoma case and polyurethane nasal packing, surgeons should be alert to the complete removal of polyurethane nasal packing after sino-nasal surgery.

PURPOSE: The aim of this study was to investigate the changes in the clinical and prognostic parameters of prostate cancer in Korean men in the eras before and after prostate-specific antigen (PSA) testing. MATERIALS AND METHODS: The medical records of 303 patients treated for prostate cancer between 1982 and 2005 were reviewed with respect to age, chief complaints, clinical stage, tumor grade, treatment options, and prognosis. We classified the patients as follows: those treated in the pre-PSA era (1982-1995, n=81), and those treated in the PSA era (1996-2000, PSA era phase 1, n=92; and 2001-2005, PSA era phase 2, n=130). RESULTS: There was no significant difference in age or clinical stage between patients treated before and those treated during the PSA era, although there was a downward migration of grade. The cancer-specific survival rates were also not different in all cases and in metastatic prostate cancer cases between the pre-PSA era and the PSA era, although the overall survival rates were significantly greater in all cases in phase 2 of the PSA era than in the pre-PSA era or in phase 1 of the PSA era (p<0.05). However, the cancer-specific survival rates for localized or locally advanced prostate cancer were significantly greater in phase 2 of the PSA era than in the pre-PSA era or in phase 1 of the PSA era (p<0.05). CONCLUSIONS: We observed a downward migration of tumor grade, but there were no migrations in the age of patients or clinical stage, and these findings have not contributed to changes in the cancer survival of Korean men with prostate cancer after the advent of PSA testing.
