Objectives: This study investigated sleep quality in female full-time homemakers and evaluated the relationship of sleep disturbance with psychological and socio-environmental factors. Methods: This cross-sectional study adopted a structured survey and sequential recruitment method for randomized participation of community-dwelling full-time female homemakers. Sleep quality and mental health were measured using the Korean version of the Pittsburgh Sleep Quality Index (K-PSQI), Korean version of the Beck Depression Inventory-II (K-BDI-II), Korean version of the Beck Anxiety Inventory (K-BAI), and Korean version of the Beck Hopelessness Scale (K-BHS). The willingness-to-pay (WTP) method was selected to measure the self-evaluated monetary value of household service work. The relationship among the main relevant factors was statistically analyzed through a mediation model. Results: A total of 166 participants were analyzed and classified having poor versus good sleep quality (poor : 24.1%, n = 40 ; good : 75.9%, n = 126 ; cut-off point = 9 on the K-PSQI). Significant between-group differences were observed in mental health status (K-BDI-II, p < 0.001 ; K-BAI, p < 0.001 ; K-BHS, p = 0.003). The moderated mediation model was verified, indicating that depression may mediate the association between nurturing burden and sleep disturbance. The path from nurturing burden to depression may be moderated by average monthly household income. Conclusion A relatively high portion of full-time female homemakers may suffer from sleep disturbance and interactions between psychological and socio-environmental factors might determine sleep quality, suggesting the need for public health policies targeting improvement of sleep quality and mental health among full-time homemakers.

PURPOSE: To assess the distinction ability for differentiating glaucoma patients based on optic disc, retinal nerve fiber layer (RNFL) and ganglion cell-inner plexiform layer (GCIPL) measured using spectral domain optical coherence tomography (SD-OCT). Additionally, the diagnostic ability of these parameters was evaluated by comparing preperimetic glaucoma patients who frequently visited the clinic and normal patients with and without a large physiologic cup/disc (C/D) ratio. METHODS: Using SD-OCT, the optic disc, RNFL and GCIPL of preperimetic glaucoma patients were compared with normal people with and without a large C/D ratio from March, 2011 to December, 2014 at Department of Ophthalmology, Inha University Hospital. Preperimetic glaucoma was defined using the normal standard automated perimetry for glaucomatous optic nerve changes such as asymmetry of vertical C/D ratio, rim thinning, notching, excavation and RNFL defect. RESULTS: When comparing preperimetic glaucoma patients to normal people without large disc cupping, the most reliable parameter for optic disc parameters, vertical C/D ratio (0.89), showed more reliable diagnostic ability than the most reliable parameter for retinal nerve fiber, inferior RNFL thickness (0.79) and superonasal and inferonasal GCIPL thickness were the most reliable GCIPL parameters (p = 0.005 and 0.002, respectively). When comparing preperimetic glaucoma patients to normal people having a large physiologic disc cupping, average C/D ratio among optic nerve parameters, inferior RNFL thickness among RNFL thickness parameters and inferior GCIPL thickness among GCIPL parameters showed highly reliable diagnostic abilities. These 3 parameters were not statistically different (all p > 0.05) and had lower distinction ability than reported in previous studies. CONCLUSIONS: Diagnostic abilities of SD-OCT for distinguishing preperimetric glaucoma from normal people having large physiologic disc cupping were similar for optic disc, RNFL and GCIPL and showed low diagnostic ability than compared to normal people without large disc cupping.

BACKGROUND: Hepatocyte growth factor (HGF) is a potent mitogenic cytokine. C-met protein, which is known to be the HGF receptor has transmembrane tyrosine kinase activity and is encoded by the c-met oncogene. The HGF/c-met signaling pathway may play various roles in the carcinogenesis of various organs. METHODS: We examined HGF and c-met mRNA expression by utilizing reverse transcription polymerase chain reaction on 40 surgically resected intracranial meningiomas (25 benign, 10 atypical, and 5 anaplastic cases). RESULTS: An HGF overexpression was detected in 28%, 50%, and 80% of the benign, atypical and anaplastic meningiomas, respectively; a high expression of HGF or the coexpression of HGF/c-met was detected in the high grade meningiomas (the atypical and anaplastic cases, p=0.046, p=0.014). An HGF expression was statistically significant in the recurrent meningiomas (p=0.003), and HGF expression was significantly lower than c-met mRNA expression in benign meningiomas (p=0.034). CONCLUSIONS: There was no correlation between histologic subtypes and HGF/c-met expression. Determination of HGF expression can be used as a molecular predictor for recurrence of meningioimas. These results suggest that HGF and c-met expression in meningiomas may be associated with anaplastic progression.

Craniopharyngiomas exhibiting histologic malignancy are extremely rare. Herein, we report the case of a 26-year-old male patient who underwent suprasellar mass excision via an interhemispheric transcallosal approach. Histopathological examination indicated that the craniopharyngioma was of the adamantinomatous subtype. The patient received postoperative medical treatment for endocrine dysfunction and diabetes mellitus without radiation treatment. Two years after the operation, he presented with progressive visual disturbance and altered mentality. Magnetic resonance imaging revealed a huge mass in the suprasellar cistern and third ventricle. He underwent a second operation via the same approach. The histopathological examination showed an adamantinomatous craniopharyngioma with sheets of solid proliferation in a spindled pattern, indicating malignant transformation. Malignant transformation of craniopharyngioma in the absence of radiation therapy has been reported in only five cases, including this one. We present a case of malignant transformation of craniopharyngioma with a brief review of relevant literature.

Vestibular schwannoma (VS) usually present the widening of internal auditory canal (IAC), and these bony changes are typically limited to IAC, not extend to temporal bone. Temporal bone invasion by VS is extremely rare. We report 51-year-old man who revealed temporal bone destruction beyond IAC by unilateral VS. The bony destruction extended anteriorly to the carotid canal and inferiorly to the jugular foramen. On histopathologic examination, the tumor showed typical benign schwannoma and did not show any unusual vascularity or malignant feature. Facial nerve was severely compressed and distorted by tumor, which unevenly eroded temporal bone in surgical field. Vestibular schwannoma with atypical invasion of temporal bone can be successfully treated with combined translabyrinthine and lateral suboccipiral approach without facial nerve dysfunction. Early detection and careful dissection of facial nerve with intraoperative monitoring should be considered during operation due to severe adhesion and distortion of facial nerve by tumor and eroded temporal bone.

PURPOSE: This study aims to evaluate early changes in retinal structure and BMP2 expression in the retina and crystalline lens by comparing streptozotocin-induced diabetic pigs and normal control group pigs. METHODS: Five eye samples from five diabetic Micro-pigs (Medikinetics, Pyeongtaek, Korea) and five eye samples from five control pigs bred in a specific pathogen-free area were used. Diabetes was developed through intravenous injection of nicotinamide and streptozotocin, and the average fasting glucose level was maintained at 250 mg/dL or higher for 16 weeks. To evaluate BMP2 expression in the retina and crystalline lens, Western blotting was performed. RESULTS: In Hematoxylin and Eosin staining, most diabetic pigs showed structural abnormalities in the inner plexiform layer. The number of nuclei in the ganglion cell layer within the range of 10⁴µm² was 3.78±0.60 for diabetic pigs and 5.57±1.07 for control group pigs, showing a statistically significant difference. In immunohistochemical staining, diabetic retinas showed an overall increase in BMP2 expression. In Western blotting, the average BMP2/actin level of diabetic retinas was 1.19±0.05, showing a significant increase compared to the 1.06±0.03 of the control group retinas (P=0.016). The BMP2/actin level of diabetic crystalline lenses was similar to the control group crystalline lenses (P=0.730). CONCLUSIONS: Compared to control group pigs, the number of nuclei in the inner nuclear layer of retinas from streptozotocin-induced diabetic pigs decreased, while an increase in BMP2 expression was observed in the retina of diabetic pigs.

BACKGROUND: The genotypes of human papillomavirus (HPV) are important in carcinogenesis in uterine cervical cancer and may be different in geographic distribution. METHODS: In 2,086 women, we analyzed the prevalence of HPV and HPV genotypes in uterine cervix by HPV-DNA chip test (n = 2,086), cytology (PAP smear, n = 1997) and biopsy (n = 546). RESULTS: Of the 2,086 cases, 1,019 cases (48.8%) were HPV-positive and 1,067 cases (51.2%) were negative for HPV. Single infection occurred most commonly (72.1% of women). HPV genotypes in the high-risk and low-risk groups, respectively were HPV-16/-58/-18/-52/-53 and HPV-70/-6/-11. The detection rates of HPV-70 in subjects older than 50 years increased significantly (p < 0.05). Infection in high risk subjects was detected in high grade lesions compared with infection in low risk subjects (p < 0.05). CONCLUSIONS: HPV-16/-58/-18/-52/-53/-70/-6/-11 genotypes were common in the patient group similar to findings in East Asia. HPV-70 infection is predominant in those older than 40 years.

Gliomatosis peritonei (GP) indicates the peritoneal implantation of mature neuroglial tissue and is usually accompanied by ovarian mature or immature teratoma. Here, we report a case of ovarian immature teratoma associated with gliomatosis involving the peritoneum, lymph nodes and Douglas' pouch, where gliomatosis coexisted with endometriosis. As far as we know, only seven cases of GP have been reported as coexisting with endometriosis. Eight cases with mature glial tissue in the lymph nodes, i.e., nodal gliomatosis, have been published either in association with GP or in its absence. Metaplasia of pluripotent coelomic stem cells has been suggested to be responsible for the pathogenesis of endometriosis and GP rather than implantation metastases of ovarian teratomatous tumor with varying maturation. This theory is also applied to GP independently of ovarian teratomatous tumors. To the best of our knowledge, nodal gliomatosis coexisting with GP and also involving endometriosis has not yet been reported.

Desmoid tumor (fibromatosis) is a histologically benign fibrous neoplasm showing locally infiltrating growth. This type of tumor commonly occurs in the abdomen, but intrathoracic desmoid tumor is uncommon. To date, 12 cases of intrathoracic desmoid tumor protruding into the pleural cavity, radiologically mimicking pleural masses, have been reported. Here, we report on a case of intrathoracic desmoid tumor protruding into the pleural cavity, and partially covered by parietal pleura. The main preoperative differential diagnoses included pleural solitary fibrous tumor, inflammatory pseudotumor or malignant mesothelioma. A near-total mass excision was performed. Pathologically, the tumor was composed of a paucicellular arrangement of spindle-shaped cells with fibromyxoid stroma. The resection margin was partially involved with spindle cells present. On histochemical staining, the spindle cells were strongly positive for vimentin and negative for CD34, consistent with a desmoid tumor. The patient was stable without further adjuvant treatment during 6-years of follow-up.
