PURPOSE: To evaluate the diagnostic value of tear film osmolarity for non-Sjogren dry eye syndrome through measuring the correlation between tear osmolarity and several conventional dry eye parameters. METHODS: In this observational cross-sectional study, 274 patients (274 eyes) with non-Sjogren dry eye syndrome were examined using tear film osmolarity and the following conventional dry eye parameters: Schirmer's test, tear film break-up time, ocular surface disease index (OSDI), and corneal staining score. The correlations between tear film osmolarity and each conventional dry eye parameter were assessed using Spearman's correlation coefficients. RESULTS: The mean tear film osmolarity of the study population was 296.34 ± 21.08 mOsm/L. The tear film osmolarity was significantly negatively correlated with the Schirmer's test value (r = -0.431, p < 0.001) and tear break-up time (r = -0.131, p = 0.031), while it was significantly positively correlated with the OSDI scores (r = 0.191, p = 0.001) and corneal staining scores (r = 0.150, p = 0.013). CONCLUSIONS: Tear film instability was significantly correlated with other conventional dry eye parameters. However, additional studies are required to determine its feasibility as a stand-alone diagnostic tool.

A green mold species that has not previously been reported in Korea was isolated from oak log beds used for shiitake (Lentinula edodes) cultivation that were infested by mushroom flies. In this study, we identify the mold species as Gliocladium viride (an anamorph of Hypocrea lutea) and describe its mycological properties. The fungus was cottony on both potato dextrose agar (PDA) and Czapek yeast extract agar (CYA), but was colored white on PDA and became yellowish green and brown on CYA. Mycelial growth on PDA attained a diameter of 73 mm at 30degrees C after 5 days. The fungus grew faster on malt extract agar (> 80 mm, 5 days at 25degrees C) compared to CYA and PDA (< 68 mm, 5 days at 25degrees C). Penicillate conidiophores of the fungus are hyaline, smooth walled, branching above typically in four stages, and 120~240 microm in length. Club-shaped or slender phialides are formed on the metulae. Conidia of the fungus were ovate and elliptic, yellowish brown and green, and 2.5~3.0 microm x 1.8~2.3 microm in size. Typically, slimy conidia are formed in a mass and colored brown to dark green to almost black. The internal transcribed spacer rDNA and translation elongation factor 1 alpha gene sequences of the fungus isolated here show 99% identity with previously identified G. viride strains.

PURPOSE: To report the first case of steroid sulfatase (STS) gene deletion, confirmed by multiplex ligation-dependent probe amplification (MLPA) analysis in identical twins with pre-Descemet corneal dystrophy associated with X-linked ichthyosis. CASE SUMMARY: 19-year old identical twin brothers with itching senses and hereditary thick scaly skin of the extremity and trunk visited our dermatologic clinic. Upon visiting, an ophthalmologic consultation with anterior segment examination showed diffuse punctate corneal opacities in the pre-Descemet layer. On MLPA analysis of the identical twin brothers, a definitive diagnosis of X-linked ichthyosis was made by identifying STS gene deletion. CONCLUSIONS: Identification of the deletion and mutation of the involved gene using gene analysis can provide insight to diagnosis and clinical characteristics of X-linked ichthyosis.

OBJECTIVE: To investigate the association between bone mineral density (BMD) and osteoporotic compression fractures in radiographic spinal osteoarthritis (OA) patients. METHODS: Subjects were 382 female patients (ages 45 to 85) from outpatient clinic for osteoporosis and rheumatic diseases. BMD was measured at lumbar spine and hip by dual X-ray absorptiometry (Hologic QDR 2000). The standard anteroposterior and lateral plain radiographs of thoracic and lumbar spine were taken to define spinal OA and vertebral compression fractures. Radiographic spinal OA was defined by grade of disc degeneration and facet joint degeneration. Frequency of vertebral fractures was compared between spinal OA and control patients in relation to their BMD, age, weight, body mass index (BMI) and years post menopause. RESULTS: Higher proportion of fracture cases were observed in spinal OA patients than non-spinal OA patients (34.1%, 44/129 vs. 18.2%, 46/253, p<0.001) despite comparable mean BMD (0.836+/-0.152 vs. 0.834+/-0.185, p=0.89) and older mean age (65.8+/-8.5 vs. 57.8+/-10.3, p<0.001). In subjects of ages from 65 to 74, spinal OA patients showed significantly higher BMD than non-spinal OA patients (0.784+/-0.125 vs. 0.719+/-0.119, p=0.007), but the frequency of fractures seems to be higher than that of non-spinal OA patients (44.9%, 22/50 patients vs. 34%,19/55 patients, p=0.58). When all study subjects were stratified according to their spine BMD (normal, osteopenia, and osteoporosis), significantly higher proportion of vertebral compression fractures was noted in spinal OA than non-spinal OA patients in osteopenia group (38.5% vs. 13.5%, p<0.001). CONCLUSION: Higher BMD does not seem to be translated directly into decreased risk of osteoporotic compression fractures in spinal OA patients. Careful assessment of risk factors for osteoporotic fractures and newer methods for assessing bone strength in this group of patients are needed.

Arteriovenous malformations (AVM) are an unusual cause of gastrointestinal (GI) bleeding. But most GI AVM can occur with GI bleeding. When conventional diagnostic studies have failed to reveal the source of GI bleeding, AVM have been one of the most common causes. But the incidence of AVM presented as bleeding of a gastric submucosal tumor is very low. A case of gastric submucosal tumor was experienced and reported as an AVM. This case is herein discussed with review of corresponding literature.

PURPOSE: Currently, holmium laser enucleation of the prostate (HoLEP) and transurethral resection of the prostate (TURP) are the standard surgical procedures used to treat benign prostatic hyperplasia (BPH). Several recent studies have demonstrated that the surgical management of BPH in patients with detrusor underactivity (DU) can effectively improve voiding symptoms, but comparative data on the efficacy of HoLEP and TURP are insufficient. Therefore, we compared the short-term surgical outcomes of HoLEP and TURP in patients with DU. METHODS: From January 2010 to May 2015, 352 patients underwent HoLEP or TURP in procedures performed by a single surgeon. Of these patients, 56 patients with both BPH and DU were enrolled in this study (HoLEP, n=24; TURP, n=32). Surgical outcomes were retrospectively compared between the 2 groups. DU was defined as a detrusor pressure at maximal flow rate of <40 cm H(2)O as measured by a pressure flow study. RESULTS: The preoperative characteristics of patients and the presence of comorbidities were comparable between the 2 groups. The TURP group showed a significantly shorter operative time than the HoLEP group (P=0.033). The weight of the resected prostate was greater in the HoLEP group, and postoperative voiding parameters, including peak flow rate and postvoid residual urine volume were significantly better in the HoLEP group than in the TURP group. CONCLUSIONS: HoLEP can be effectively and safely performed in patients with DU and can be expected to have better surgical outcomes than TURP in terms of the improvement in lower urinary tract symptoms.
