Iridocorneal endothelial syndrome is a disease characterized by corneal endothelial degeneration, corneal edema, peripheral anterior synechia, iris stromal change, and secondary glaucoma. This syndrome is considered to have three major variations: Chandler's syndrome, progressive (essential) iris atrophy, and Cogan-Reese syndrome. We experienced three cases of iridocorneal endothelial syndrome with transient intraocular pressure elevation.

PURPOSE: The aim of the present study was to evaluate the effect of Bio-Oss on bone formation in terms of healing period and type of membrane so that determine the most suitable condition for implant fixation in grafted maxilla. MATERIAL AND METHOD: Forty-five biopsy specimens from graft site were evaluated. Sinus lift was performed in the patients with reduced alveolar bone height(less than 5mm). The specimen was taken at the time of implant fixation, which was performed at least 5 months after the sinus lift procedure. All specimens were stained with HandE and Trichrome staining and evaluated histomorphometrically. RESULT: The results showed that Bio-Oss particle was in direct contact with newly formed bone in all cases. In the present study, the amount of newly formed bone and the residual bone substitute material were not statistically different according to various membrane and different healing period. There was no difference between the histological feature of the specimen of 5 and 31 months. No statistical significance was detected between male and female. CONCLUSION: The result implies that Bio-Oss does not seem to be resorbed over time regardless of the type of the membranes. The further investigation is needed to clarify this issue with the extended period of follow-up.

To investigate the risk factors and clinical characteristics of postrenal transplant diabetes mellitus (PTDM), we reviewed the records of 177 renal allograft recipients in Maryknoll Hospiatal whose allografts had functioned longer than 6 months. Nineteen patients (10.7%) developed PTDM at 5.0+/-7.8 (1-52) months; 9 (47%) of these within 1 month. PTDM patients were older than nondiabetic renal transplants (42+/-2 vs 37+/-1 years, P<0.05). Body mass index tended to be higher in PTDM (23.5+/-1.0 vs 21.8+/-0.3kg/m2, P=0.09). Number of acute rejections (0.6+/-0.2 vs 0.5+/-0.1) and serum creatinine at 1 year after transplantation (1.2+/-0.8 vs 1.3+/-0.3mg/dL) were not different. Fasting (103.6+/-10.4 vs 84.4+/-1.6mg/dL, P<0.05) and postprandial (189.2+/-24.8 vs 118.6+/-2.3 mg/dL, P<0.01) blood sugars, measured before transplantation, were higher in PTDM. CsA blood level at 1 month posttransplantation was higher in PTDM (350+/-34 vs 279+/-8ng/mL, P<0.05). Fasting serum insulin was significantly higher (28.2+/-12.2 vs 7.3+/-2.0 microunit/dL, P<0.05) and serum C-peptide tended to be higher in PTDM patients compared with euglycemic renal recipients (6.3+/-1.6 vs 3.8+/-0.9ng/dL, P=0.08). All the PTDM patients were treated by either insulin or oral agent; 15 of 19 required no treatment after 4.7+/-6.9 months. In conclusion, prevalence of PTDM was 10.7%. PTDM patients were older. Body mass index was tended to be higher. Fasting and postprandial blood sugars, measured before transplantation, were higher in PTDM. Faslting serum insulin was higher and C-peptide tended to be higher in diabetics. These results suggested that increased insulin resistance plays a major role in the pathogenesis of PTDM.

To understand the role of IGF2 gene in development of human ovary, IGF2 expression was detected by monoclonal antibody for IGF2 to its producted protein with immunohistochemical technique on human ovarian tissues. The results was as follows. IGF2 was highly expressed in ovum of mature follicle, IGF2 expression, however, was not high in granulosa and the cells. IGF2 was not highly expressed in ovum of primary follicle. Highly expressed IGF2 was found on corpus luteum and no expression of IGF2 was found in stroma and epithelial cells. These results suggest that IGF2 is important role in ovulation and in production of progesterone. Abnormal IGF2 expression may be concerned to carcinogenesis of ovarian tumor because most of all tumor from ovary is originated from epithelium.

PURPOSE: To evaluate differential changes in the central and nasal fat pads of the upper eyelid associated with aging and the effect of body mass index in Koreans. METHODS: Using a standardized scale, the volume grade of the central and nasal fat pads was graded from 0 to 3 (0 for depressed, 1 for flat, 2 for mildly protruded, and 3 for markedly protruded) in normal adults, consisting of 20 males and 20 females from 30 years of age to 80 years of age. The body mass index was calculated for every patient through interviews using their height and weight. Statistical evaluations correlating age and body mass index with central and nasal fat pad changes were performed. Statistical evaluations correlating age with fat pad changes except for the effect of body mass index were performed. RESULTS: Except for the effect of body mass index, the central fat pad increased (r = -0.176, p = 0.007) and nasal fat pad decreased (r = 0.252, p < 0.001) with aging, which was statistically significant. CONCLUSIONS: With aging, the central fat pad increases and nasal fat pad decreases in the upper eyelid. Clinically, this finding has implications in cosmetic and functional upper eyelid blepharoplasty. In addition, the results may be useful to determine whether to conserve or remove the fat as well as the amount of fat removal during upper blepharoplasty.

Epithelioid hemangioendothelioma (EHE) is a rare vascular tumor that has been reported in systemic organs and in the skin as a biologically "borderline" neoplasm with intermediate malignant potentials. Skin involvement in EHE is rare, but when present, it occurs most commonly in the upper and lower extremities, presenting as a solitary, slightly painful, soft tissue mass. Skin involvement is often associated with underlying soft tissues or bone tumors. Histopathological study reveals cords and nests of epithelioid endothelial cells in a myxoid or hyalinized background and small intracytoplasmic vacuoles containing red blood cells. There have been no reported cases yet describing the dermoscopic features of EHE. Herein, we describe a young woman who developed cutaneous EHE that enlarged during pregnancy, we provided the dermoscopic findings and a review of the relevant literature.

BACKGROUND AND PURPOSE: Hypertrophic pachymeningitis (HP) is a rare disease caused by autoimmunity in the meninx that causes various neurologic symptoms, including headache, seizures, weakness, paresthesia, and cranial nerve palsies. Although the first-line therapy for HP is steroids, many HP cases are refractory to steroids or recur when the steroids are tapered. Here we report three HP cases that were successfully treated with rituximab (RTX). METHODS: From an institutional cohort recruited from April 2012 to July 2016, three HP cases that were identified to be steroid-refractory were treated with RTX (four weekly doses of 375 mg/m²). Clinical improvement was assessed by the number of relapses of any neurologic symptom and the largest dural thickness in MRI. RESULTS: All three patients were recurrence-free of neurologic symptoms and exhibited prominent decreases in the dural thickness after RTX treatment. No adverse events were observed in the patients. CONCLUSIONS: We suggest RTX as a second-line therapy for steroid-refractory HP. Further studies are warranted to confirm this observation in a larger population and to consider RTX as a first-line therapy.

BACKGROUND: As the immunocompromised population has increased in recent years, the number of cutaneous nontuberculous mycobacterial (NTM) infections has also risen. However, since this affliction has no pathognomonic clinical or histological features, the diagnosis and treatment of cutaneous NTM infections are often delayed. OBJECTIVE: The aim of this study was to investigate the microbiological, clinical, and histological findings of cutaneous NTM infections. METHODS: We reviewed medical records and histologic slides of 10 patients diagnosed with cutaneous NTM infections confirmed by culture or polymerase chain reaction. RESULTS: All patients except one were immunocompetent, and 5 of 10 patients had preceding factors including trauma, liposuction, and intralesional triamcinolone injection. Microbiologically, of the 10 infections, 5 were caused by Mycobacterium marinum, 3 by Mycobacterium fortuitum, and 1 each by Mycobacterium chelonae and Mycobacterium ulcerans, respectively. Of the 5 patients with M. marinum, 2 had a fish-related job and 1 reared fish at a home aquarium. The most common clinical presentation was erythematous nodules (7/10). Histologically, irregular acanthosis (4/10), mixed cell infiltrate of lymphocytes, histiocytes, neutrophils (9/10), suppurative granuloma (7/10), microcysts lined by neutrophils (5/10), fibrosis (4/10), and panniculitis (7/10) were identified. CONCLUSION: We found microcysts lined by neutrophils in 50% of the samples and considered this finding to be a diagnostic marker of NTM infection. These clinicopathologic features will assist clinicians in diagnosing NTM infection more rapidly and accurately.

Iododerma is a rare cutaneous eruption that occurs after oral, parenteral or topical administration of iodides. Acneiform papulopustular lesions are the most common skin reactions of iododerma and erythematous, vesiculobullous, vegetative, and pustular psoriasis-like lesions appear less commonly. A 40-year-old woman with post-thyroidectomy presented with pustular and crusted patches with erythematous and indurated bases on the face and well-defined purplish crusted desquamative plaques on the lower legs at 10 days after radioactive iodine-131 ablation. Based on clinicopathological findings and history, she was diagnosed with iododerma following radioactive iodine ablation. Hypersensitivity to iodine is more uncommon in iodine-131 therapy compared with other iodine-containing substances since the quantity of sodium iodide is infinitely small. As iododerma following radioactive iodine ablation is a rare entity, so clinicians need to know about the possibilities of developing the skin lesion along with other early side effects before administering iodine-131 therapy.
