PURPOSE: To evaluate the changes of axial length (AXL) in eyes with unilateral idiopathic central serous chorioretinopathy (CSC) after resolution of serous retinal detachment. METHODS: A total of 31 patients diagnosed with idiopathic unilateral CSC were included in this study. The changes of AXL according to serous retinal detachment were examined. The keratometric value and AXL were measured using partial coherence interferometry. Serous retinal detachment and central macular thickness (CMT) were measured by spectral domain optical coherence tomography. RESULTS: The mean age of the 31 CSC patients, including 19 males, was 42.7 years. The AXL was significantly increased from 23.41 to 23.58 mm after resolution of serous retinal detachment (p < 0.001). The CMT was significantly decreased from 413.4 to 226.8 µm after resolution of serous retinal detachment (p < 0.001). The differences in AXL correlated with CMT differences and subretinal fluid height (r = −0.616, p < 0.001 and r = −0.637, p < 0.001, respectively), and the best-corrected visual acuity was significantly different after resolution of serous retinal detachment (p < 0.001). CONCLUSIONS: In unilateral idiopathic CSC with serous retinal detachment, a shortened AXL in the acute phase was restored after resolution of serous retinal detachment.

PURPOSE: Deproteinized bovine bone substitutes are commonly used in dental regenerative surgery for treatment of alveolar defects. In this study, three different bovine bone minerals - OCS-B (NIBEC, Seoul, Korea), Bio-Oss (Geistlich - Pharma, Switzerland), Osteograft/N - 300 (OGN, Dentsply Friadent Ceramed. TN, USA) - were investigated to analyze the basic characteristics of commercially available bone substitutes. METHODS:Their physicochemical properties were evaluated by scanning electron microscopy, energy dispersive X-ray spectrometer (EDS), surface area analysis, and Kjeldahl protein analysis. Cell proliferation and alkaline phosphatase (ALP) activity of human osteosarcoma cells on different bovine bone minerals were evaluated. RESULTS: Three kinds of bone substitutes displayed different surface properties. Ca/P ratio of OCS - B shown to be lower than other two bovine bone minerals in EDS analysis. Bio-Oss had wider surface area and lower amount of residual protein than OCS - B and OGN. In addition Bio - Oss was proved to have lower cell proliferation and ALP activity due to lots of residual micro particles, compared with OCS - B and OGN. CONCLUSIONS: Based on the results of this study, three bovine bone minerals that produced by similar methods appear to have different property and characteristics. It is suggested that detailed studies and quality management is needed in operations for dental use and its biological effects on new bone formation.

We report a case of trichoblastic fibroma involving the scrotum in a 60-year-old man. Trichoblastic fibroma is very rare and benign trichogenic tumor that has both epithelial and mesenchymal components and histologically recount the embryologic development of the hair follicle. The diagnosis was confirmed by histopathologic examination.

Purpose:
We report the clinical outcomes of retinal capillary hemangioma (RCH) after the application of various treatments.
Methods:
We performed a retrospective chart analysis of eight eyes treated for RCH between August 2009 and January 2018. During the follow-up period, the status and progression of the RCHs were checked by fundus photography, fluorescein angiography, and optical coherence tomography, and additional treatments were applied when necessary.
Results:
Three of the five patients had bilateral RCH, and two had unilateral RCH. Six eyes received laser photocoagulation; two eyes received cryotherapy, and one eye received intravitreal Avastin injection. Three eyes each had intravitreal triamcinolone injection, subtenon triamcinolone injection, and intravitreal dexamethasone injection to control inflammation. Also, two patients took oral prednisolone, and one patient used prednisolone eye drops to control inflammation. Two eyes underwent vitrectomy and scleral buckling due to deterioration of the epiretinal membrane and vitreal traction, respectively. As a result of those treatments, the tumors were stable in five of the eight eyes. However, one eye is now in a pre-phthisis state, and one patient who refused treatment showed progression of the tumor, epiretinal membrane, and traction.
Conclusions
Because RCHs vary in size, the degree of inflammation, and symptoms, this disorder should be actively treated on a case-by-case basis. Fluorescein angiography should be used periodically to determine recurrence of the tumor or inflammation, and the appropriate treatment should be repeated as necessary. Moreover, regular systemic screening tests for von Hippel-Lindau disease should be performed in RCH patients to ensure that they have no abnormalities other than in the eye.

OBJECTIVES: Inadequate antibody responses to pathogens may lead to the recurrence of otitis media with effusion (OME). Although B-cell production by antibodies is controlled by transcription factors, the status of these factors has not been assessed in patients with OME. METHODS: Expression of immunoglobulin was measured by enzyme-linked immunosorbent assay. Expression of transcription factors Bcl-6, Blimp-1, Pax-5, and XBP-1 was assessed by RT-PCR in the middle-ear fluid of 29 children with >4 OME episodes in 12 months or >3 episodes in 6 months (the OME-prone group) and in 32 children with <3 OME episodes in 12 months (OME group). The relationship between recurrence of OME and expression levels of immunoglobulins and transcription factors in middle-ear fluid was determined. RESULTS: The concentration of IgA in middle-ear fluid was significantly lower in the OME-prone than in the OME group, as was the expression of mRNA encoding the transcription factors Blimp-1 and XBP-1 (P<0.05 each). Expression of mRNA encoding the transcription factors Bcl-6 and Pax-5 was more intense in the OME-prone than in the OME group, but these differences were not significant (P>0.05). CONCLUSION: Lower concentrations of IgA, Blimp-1 and XBP-1 in middle ear fluid of patients with OME may be related to OME recurrence and chronicity.

BACKGROUND: Defective or immature antibody responses to pathogens in children may explain the increased susceptibility to acute otitis media. However, there is no study in Korea patients whether a correlation exists between otitis media with effusion and the levels of serum immunoglobulins, IgG subclasses, IgA, IgM and IgE. METHODS: 45 children with otitis media with effusion more than 4 episodes in 12 months or 3 episodes in 6 months, 62 children with otitis media with effusion less than 3 episodes in 12 months and 102 children for control group took part in the study at the Department of Otorhinolaryngology of the KyungHee University from May 2004 to Feburary 2007. Serum immunoglobulin levels were determined by nephelometry. And then the relationship between otitis media with effusion and serum immunoglobulin level was evaluated. RESULTS: In otitis media prone group, serum IgG1, IgG2, IgG4, and IgA level was lower than those level of control group, it was significantly decreased (p<0.05). In otitis media group, serum IgA, IgE, and IgG4 level was lower than those level of control. But it was not statistically significant (p>0.05). CONCLUSION: Lower immunoglobulins in children with otitis media with effusion suggest a generalized decreased antibody responses. Lower levels of serum IgG1, IgG2, IgG4, and IgA may be related with chronicity or intractability of otitis media with effusion.
