Prostatic abscess is seen infrequently. Furthermore small abscess or microabscess accompanied with BPH or chronic prostatitis is likely to be overlooked and very difficult to diagnose with history and physical examination due to obscurity of its clinical symptoms. We have experienced frequent pus discharge from resected area of prostate during transurethral resection in patients with BPH and/or chronic prostatitis. And through clinical observation of 32 patients with BPH and 7 patients with chronic prostatitis whom we had treated by transurethral resection of prostate following results were obtained. 1. Prostatic abscess was found in 26 cases of 39 patients with BPH and/or chronic prostatitis during transurethral resection of prostate. 2. Transvesical and transrectal ultrasonography of prostate may increase the chances to diagnose small abscess with sensitivity of 46%. 3. Urinary tract infection and concomitant prostatic calculi with lower urinary tract obstruction were important predisposing factors in formation of prostatic abscess. 4. Diabetes mellitus was accompanied in 5 cases of 26 patients of prostatic abscess. 5. Definite drainage with transurethral resection of the gland and the use of broad spectrum antibiotics brought good results.

Huntington's disease (HD) is a late-onset and progressive neurodegenerative disorder that is caused by aggregation of mutant huntingtin protein which contains expanded-polyglutamine. The molecular chaperones modulate the aggregation in early stage and known for the most potent protector of neurodegeneration in animal models of HD. Over the past decades, a number of studies have demonstrated molecular chaperones alleviate the pathogenic symptoms by polyQ-mediated toxicity. Moreover, chaperone-inducible drugs and anti-aggregation drugs have beneficial effects on symptoms of disease. Here, we focus on the function of molecular chaperone in animal models of HD, and review the recent therapeutic approaches to modulate expression and turn-over of molecular chaperone and to develop anti-aggregation drugs.

PURPOSE: To compare the 1-year outcome of 1.8 mm and 2.2 mm microcoaxial cataract surgery (MCCS) versus 2.75 mm conventional cataract surgery (CCS). METHODS: The present study evaluated 120 eyes (40 eyes in each group). The mean ultrasound power, ultrasound time (UST), and cumulative dissipated energy (CDE) were measured preoperatively and at 1 day, 1, 2, 6 months, and 1 year postoperative. Visual acuity, number of corneal endothelial cells, and surgically induced astigmatism (SIA) were compared. RESULTS: In LOCS III NO4, 1.8 mm MCCS showed a statistically higher ultrasound time (p-value = 0.031) and CDE (p-value = 0.029), and the day 1 corneal thickness increase was relatively higher in 1.8 mm MCCS (p-value = 0.043) than other two groups. There were no differences in postoperative 1 year visual acuity or number of corneal endothelial cells among the groups. SIA was significantly lower in 1.8 mm and 2.2 mm MCCS compared to that of the conventional treatment (p-value = 0.046). CONCLUSIONS: There were no differences in postoperative 1 year mean endothelial cell density or corrected visual acuity between 1.8 and 2.2 mm MCCS and CCS at all cataract densities. The 1.8 mm and 2.2 mm MCCS techniques were as safe and effective as CCS, and SIA in 1.8 mm and 2.2 mm MCCS was significantly lower than that of CCS.

PURPOSE: To evaluate the factors affecting corneal endothelial cell loss after penetrating keratoplasty in a long-term follow-up. METHODS: Donor age, post-mortem time, storage time, underlying disease, elevation of IOP after surgery, underlying glaucoma, and trephine size were analyzed in 76 eyes. Postoperative corneal endothelial density was measured after 1, 3, 6, and 12 months. Patients who experienced graft rejection were excluded. RESULTS: Donor age and endothelial loss were correlated in all patients (t-value = 1.98); however, post-mortem time and storage time were not statistically significant (t 2 < 2). Endothelial cell loss was more severe in the bullous keratopathy patient group than it was in the keratoconus patient group, but this difference was not statistically significant (p-value = 0.154). The number of anti-glaucomatous eye drops showed positive correlation with the declining rate of endothelial cells (t-value = 1.975). Existence of glaucoma diagnosed before surgery did not statistically influence endothelial cell loss. Additionally, in the bullous keratopathy patient group, an inverse correlation between endothelial cell loss and trephine diameter was observed (t-value = -2.859). CONCLUSIONS: Old donor age, small trephine size in bullous keratopathy, and post-operative IOP elevation are risk factors for increased endothelial cell loss following penetrating keratoplasty.

Placenta percreta with bladder invasion is an extremely rare complication causing life-threatening hemorrhage, up to 17 liters.1 Most reported cases have been diagnosed after 30 weeks of pregnancy and few have presented before 20 weeks.2 Only 20 cases of placenta percreta with invasion of the bladder have been reported during last decade. In this condition, chorionic villi attach directly to the myometrium without intervening decidua. The exact etiology of impaired decidualization is unknown; however, a previous endometrial insult, such as previous cesarian section or endometrial curettage may be a contributing factor. To avoid massive bleeding, uterine body incision, hypogastric artery ligation before hysterectomy and uterine cervical removal have been attempted.1 Chorionic villi may attach to the myometrium (accreta), invade the myometrium(increta), or in its severe form (percreta) the trophoblastic tissue penetrates the whole myometrium and invades adjacent structures. We experienced a case of placenta previa percreta with bladder invasion and review the literatures.

OBJECTIVES: This pre-clinical study was performed to assess the effects of ethaverine in the two kinds of behavioral models of depression in rats. METHODS: We observed the changes of the immobility time in the forced swimming test and the quantity of sucrose consumed in the chronic mild stress model, using ethaverine(20mg/kg) alone, imipramine(20mg/kg) alone, or ethaverine and imipramine concomitantly. RESULTS: In the forced swimming test, both single treatment and chronic treatment(for 7 days) with imipramine or ethaverine significantly reduced the immobility time, and concomitant chronic treatment with ethaverine potentiated the effect of imipramine. In the chronic mild stress model, both imipramine and ethaverine reversed the decreased sucrose consumption induced by 3-week stress and concomitantly treated ethaverine potentiated the effect of imipramine in the early phase of treatment. CONCLUSIONS: The data suggest that ethaverine can be used alone or concomitantly with other anti-depressants in the clinical situation.

The effects of a L-type calcium channel blocker, ethaverine were investigated in the rat forced swimming test, after single and repeated administration. Ethaverine in doses of 20 mg/kg, 40 mg/kg after single and repeated administration reduced significantly the duration of immobility in the forced swimming test. Fluoxetine administered in a single dose of 40 mg/kg did not influence the duration of immobility, but fluoxetine in a dose of 40 mg/kg administered repeatedly reduced significantly the duration of immobility. Ethaverine in a dose of 10 mg/kg did not affect the immobility after single and repeated administration. Imipramine and fluoxetine in doses which were not effective by themselves, increased the immobilityreducing effect when administered concormitantly with ethaverine in a dose of 10 mg/kg. Imipramine in a dose of 20 mg/kg and fluoxetine in a dose of 80 mg/kg, administered alone reduced the immobility time. The reduction of immobility after the concormitant administration of ethaverine in a dose of 10 mg/kg and imipramine in a dose of 20 mg/kg, fluoxetine in a dose of 80 mg/kg was significantly greater than after imipramine or fluoxetine, administered alone. The anti-immobility effect of the ethaverine was significantly counteracted by haloperidol in a dose of 0.5 mg/kg. The effects of ethaverine on the levels of monoamines and their metabolites were also investigated in rat striatum, cerebral cortex, cerebellum, medulla oblongata, hypothalamus, midbrain, hippocampus. Treatment with ethaverine caused alterations on the levels of dopamine and its metabolite in rat striatum, cerebral cortex, hypothalamus, medulla oblongata, cerebellum, but not on the levels of norepinephrine and serotonin and its metabolite. The observed effects of ethaverine indicate that ethaverine may have an antidepressant activity and may interact with the brain dopaminergic system. The present results suggest that the concormitant administration of ethaverine and antidepressants may have a more potent therapeutic antidepressant effect and/or may permit reduction of the dose of antidepressant and thus diminish its side effects.

PURPOSE: We investigated systemic risk factors for clinically significant macula edema (CSME) within 1 year after pan-retinal photocoagulation in patients with proliferative diabetic retinopathy. METHODS: A retrospective chart review was performed on 171 patients who received pan-retinal photocoagulation at our hospital from January 2010 to December 2016. The patients were divided into Group Ⅰ with CSME (85 eyes) and Group II without CSME (86 eyes). The associations between presence of CSME and glycated hemoglobin (HbA1c), duration of diabetes, systolic and diastolic blood pressure (BP), body mass index (BMI), lipid status, sex, and estimated glomerular filtration rate (eGFR) were evaluated. RESULTS: In the present study of 171 patients, there was no significant difference in age and gender distribution between the two groups. Duration of diabetes, total serum cholesterol, serum low density lipoprotein, HbA1c, and eGFR were significantly higher in patients with CSME (p < 0.05). Serum high-density lipoprotein, triglycerides, BMI, and systolic and diastolic BP showed no correlation with CSME. Multiple logistic regression analysis showed that total serum cholesterol and HbA1c values had significantly high odds of developing CSME. CONCLUSIONS: HbA1c, total serum cholesterol, and eGFR are important risk factors associated with CSME in patients with proliferative diabetic retinopathy secondary to pan-retinal photocoagulation. Thus, early detection of these risk factors and their control have significant roles in preventing the development and progression of maculopathy and thereby preventing severe visual loss.
