We present two cases of adrenocortical oncocytomas that were well-delineated on multi-detector computed tomography and magnetic resonance imaging. The images showed a well-enhanced large mass with multiple stippled calcifications in a 10-yr-old girl who was consulted due to precocious puberty. A well-enhanced solid mass with necrotic components was incidentally noticed in a 54-yr-old man. These lesions were resected and diagnosed as adrenocortical oncocytomas through immunohistochemical studies and electron microscopy. Adrenocortical oncocytomas are rare disease entities, therefore, we report these interesting, rare adrenocortical oncocytomas here with radiologic findings, and discuss differential diagnosis.

This study was undertaken to document the effect of transforming growth factor-beta2 (TGF-beta2(TGF-beta2) and basic fibroblast growth factor (bFGF) on the proliferation of pig retinal pigment epithelial cells (RPE). Whereas bFGF increased the proliferation, TGF-beta2 showed the inhibitory effect on the proliferation The inhibitory effect of TGF-beta2 disappeared in RPE subcultured with 10ng/ml of bFGF. Both TGF-beta2- and bFGF-specific antisense oligonucleotides blocked the autocrine effect of the growth factors. PLC-71 -specific antisense oligonucleotide inhibited the effect of TGF-beta2 and bFGF. Genistein inhibited the effect of TGF-beta2 and bFGF in dose-dependent man, ner. The data suggest the involvement. of in PLC-/1 and tyrosine kinase in signalling.

PURPOSE: To investigate the time course and occurrence of foveal retinal detachment presenting with symptoms of metamorphopsia and decreased visual acuity after successful surgery for macula-off retinal detachment. METHODS: This study included 9 eyes of 9 patients who were diagnosed with foveal retinal detachment using optical coherence tomography (OCT) among 198 patients who had decreased visual acuity and metamorphopsia after successful rhegmatogenous retinal detachment surgery. RESULTS: All eyes were diagnosed with foveal retinal detachment by OCT. Foveal retinal detachment occurred after scleral buckling surgery in 8 eyes (88%) and after vitrectomy and pneumoretinopexy in 1 eye. The degree and frequency of foveal retinal detachment was milder and lower after vitrectomy and pneumoretinopexy than after scleral buckling surgery. All foveal retinal detachments were reattached spontaneously after 9 months (range, 5~14 months). In all eyes, the symptom of metamorphopsia was improved and visual acuity increased after the foveal retinal detachment was reattached. CONCLUSIONS: OCT can be used to diagnose foveal retinal detachment in cases when the fundus and fluorescein angiography do not show specific findings but, presenting symptoms of decreased visual acuity and metamorphopsia. In all cases evaluated, the foveal retinal detachment was reattached spontaneously without treatment.

Penile amputation is quite rare and requires emergency reimplantation by using microvascular surgery. Herein we report a case of an 8-year-old boy who accidentally has his penis amputated during circumcision. Emergency reimplantation was performed by using microvascular surgery. Thereafter partial necrosis of glans penis and distal penile skin was noted So penoplasty by using scrotal skin was done to restore normal shape penis. After 6 months later, normal erection and sensation were restored.

PURPOSE: To compare the outcomes of indocyanine green (ICG) and triamcinolone (TA) assisted internal limiting membrane (ILM) peeling during idiopathic macular hole surgery. METHODS: Fifty-four eyes of 54 patients with idiopathic macular hole underwent pars plana vitrectomy including peeling of the posterior cortical hyaloid and peeling of the internal limiting membrane. For enhanced visualization of ILM, ICG was used in 25 eyes and TA in the remaining 29 eyes. Postoperative visual acuity was measured and OCT was performed. RESULTS: Anatomical closure was achieved in 25 eyes (100%) in ICG group and 28 eyes (97%) in TA group, Best corrected visual acuity improvement by > or =2 lines was in 15 eyes (60%) in ICG group and 18 eyes (62%) in TA group. Postoperative visual improvement rates by > or =20/50 were 10 eyes (40%) in ICG group and 9 eyes (31%) in TA group. CONCLUSIONS: Peeling of the internal limiting membrane using triamcinolone and indocyanine green was safe and effective for anatomic and functional success in idiopathic macular hole surgery. Further studies of the toxicity of TA, ICG and the result of internal limiting membrane peeling is needed.

Posterior segment injuries due to non-penetrating ocular trauma have protean ocular manifestations. Vision may be unaffected or completely lost according to the injured area. Although most cases require no specific treatment, early accurate diagnosis and appropriate prophylactic treatment will prevent some patients from late visual loss. We analyzed retrospectively 36 eyes of 36 patients with non-penetrating posterior segment trauma who had visited our clinic from August, 1994 to February, 1997. Thirty two of the patients(88.8%) were male and the peak age group was in the third decade. Thirteen of the patients(21%) had Berlin`s edema, which was one of the most common findings seen in the posterior segment. The most common anterior segment finding associated with non-penetrating ocular trauma was hyphema(20%). The most common cause of non-penetrating trauma was violence(first, foot)(38.8%). Final visual acuity was better in eyes without the lesion involving the macula.
