Cleft lip and palate is congenital deformity in oral and maxillofacial area. Normal soft palate has velopharyngeal closure action by connecting oral cavity and nasal cavity at rest and moving upward at swallowing and specific pronunciation. Cleft palate patients with velopharyngeal insufficiency have difficulty in mastication, swallowing and pronunciation because velopharyngeal closure is incomplete. At this time, a prosthetic device used to cover palate defects is called a palatal obturator. A palatal obturator separates oral cavity and nasal cavity and recovers pronunciation, mastication, swallowing and esthetic function. The purpose of this case study is to report the results because it reaches a satisfactory result in functional and esthetic aspects through functional impression procedures using modeling compound and tissue conditioner for restoration of a cleft palate patient with velopharyngeal insufficiency.

Inflammation is a series of host defense processes in response to microbial infection and tissue injury. Inflammatory processes frequently cause extracellular acidification in the inflamed region through increased glycolysis and lactate secretion. Therefore, the immune cells infiltrating the inflamed region encounter an acidic microenvironment. Extracellular acidosis can modulate the innate immune response of macrophages; however, its role for inflammasome signaling still remains elusive. In the present study, we demonstrated that macrophages exposed to an acidic microenvironment exhibited enhanced caspase-1 processing and IL-1β secretion compared with those under physiological pH. Moreover, exposure to an acidic pH increased the ability of macrophages to assemble the NLR family pyrin domain containing 3 (NLRP3) inflammasome in response to an NLRP3 agonist.This acidosis-mediated augmentation of NLRP3 inflammasome activation occurred in bone marrow-derived macrophages but not in bone marrow-derived neutrophils. Notably, exposure to an acidic environment caused a reduction in the intracellular pH of macrophages but not neutrophils. Concordantly, macrophages, but not neutrophils, exhibited NLRP3 agonist-mediated translocation of chloride intracellular channel protein 1 (CLIC1) into their plasma membranes under an acidic microenvironment. Collectively, our results demonstrate that extracellular acidosis during inflammation can increase the sensitivity of NLRP3 inflammasome formation and activation in a CLIC1-dependent manner. Thus, CLIC1 may be a potential therapeutic target for NLRP3 inflammasome-mediated pathological conditions.

PURPOSE: Retinopathy, neuropathy, and nephropathy are well-known complications of diabetes; they are often expected to occur and, therefore, are usually tested for. However, urogenital complications, such as sexual and voiding dysfunctions, are less well known, and consequently, many patients are not treated appropriately despite their symptoms. Thus, we surveyed diabetic patients with regard to their perception of urogenital complications. MATERIALS AND METHODS: We designed a survey for patients in our hospital who were being treated for diabetes mellitus (DM). The questionnaire included items on age, sex, treatment duration, treatment options for and the level of perception of urogenital symptoms, the presence of urogenital symptoms, and whether treatment was intended or had been initiated. RESULTS: In total, 275 patients participated in the survey. The perception questions on DM-associated urogenital complications showed that 89 patients (32.4%) had no knowledge, 84 patients (30.5%) had some knowledge, and 102 patients (37.1%) had detailed knowledge about these complications. A total of 124 patients (45.1%) reported urogenital symptoms: 93 patients (75.0%) reported voiding dysfunction and 61 patients (49.2%) reported sexual dysfunction. Common symptoms of voiding dysfunction were urinary frequency, nocturia, sense of residual urine, weak stream, and urinary incontinence. Common symptoms of sexual dysfunction were reduced libido, and erectile and ejaculatory dysfunction. CONCLUSIONS: The survey showed that the subjective prevalence rate of urogenital symptoms in diabetic patients was 45.1%. However, only a small percentage (37.1%) of the patients cognized that these symptoms were associated with DM. Therefore, it is necessary to properly inform and educate diabetic patients on possible urogenital complications that may occur.

PURPOSE: This study was performed to investigate the discomfort reported by patients taking phosphodiesterase type 5 inhibitors (PDE5Is) in clinical practice. MATERIALS AND METHODS: From September 2011 to March 2012, we surveyed patients who were prescribed PDE5Is for erectile dysfunction (ED). The questionnaire elicited information concerning: patient characteristics, medication counseling received and inconveniences experienced in hospitals and at pharmacies, effects of PDE5Is, and the separation of the prescribing and the dispensing of PDE5Is. RESULTS: A total of 237 patients completed the questionnaire (mean age: 58.81+/-9.14 years). Among the 62 patients (26.0%) who reported having encountered some inconveniences in hospitals, the most frequently expressed concerns 'assistant staff,' including nurses (38.7%), 'testing procedures' (27.4%), and 'the issuing of prescriptions' (22.6%). Of the 137 patients (57.8%) who noted inconveniences in obtaining medications from pharmacies, 60.6% cited 'self-consciousness' as the most common reason, followed by 'insufficient medication counseling' (22.6%), and 'absence of consultation' (11.6%). In contrast, 82% of the patients were satisfied with the medication counseling that they had received in hospitals, covering drug usage, side effects, and precautions regarding PDE5Is; this proportion was only 30% for pharmacies. Further, most patients (89%) indicated that they preferred to obtain their prescriptions and medications for ED from the hospital at the same time. CONCLUSIONS: Treatment of ED is a highly private matter. According to the survey, ED patients more often felt that obtaining medication from pharmacies was inconvenient. The sociocultural aspects of ED necessitate that exceptions to separating the prescribing and the dispensing of medication be considered.

The combination of symptomatic hypopharyngeal webs and iron-deficiency anemia in middle-aged women constitutes Plummer-Vinson syndrome. It is uncommon but important syndrome because of inceased risk of squamous cell carcinoma of the pharynx and esophagus. The cause of this syndrome is still not clear. A small sized web is treated by correction of anemia, but a large sized one with dysphagia is treated by breakage of web. Recently, we experienced a 41-year-old woman with Plummer-Vinson syndrome. She complained of dysphagia for 10 years. Esophagogram and endoscopic examination showed a hypopharyngeal web and peripheral blood profile was compatible with iron-deficiency anemia. Her symptom improved after endoscopic balloon dilatation of the upper esophageal web.

We recently encountered a case of stuttering priapism in a 41-year-old patient with neurosyphilis. Priapism very rarely has a neurogenic cause, and to our knowledge, priapism caused by neurosyphilis has not been reported previously in the literature. Our aim was to report this case and systematically review the related literature.

BACKGROUND: Broad-spectrum antibiotic therapy has been recommended as an empirical regimen in cancer patients with febrile neutropenia. Cefepime is a fourth generation cephalosporin with good activity against both gram-positive cocci and gram-negative bacilli. MATERIALS AND METHODS: To compare the efficacy and safety of cefepime alone with ceftazidime plus tobramycin as empirical regimen for adult cancer patients with febrile neutropenia, a randomized, open label, comparative trial was performed. If the patient showed clinical improvent 72 hours, antibiotic could be changed to oral ciprofloxacin. Clinical and microbiological responses were determined at 72 hours and at the end of therapy. To investigate the antimicrobial resistance of viridans streptococci, swab cultures were obtained from throat in all enrolled patients and antimicrobial susceptibility tests were performed by using microdilution method according to the NCCLS. RESULTS: A total of 89 patients were enrolled. Forty-eight patients received cefepime alone (CA), and 41 patients received ceftazidime plus tobramycin (CT). Demographic and baseline clinical characteristics were similar in both groups (P>0.05). The initial clinical success rate at day 2-4 in group CA (91.7%) was similar with that in CT group (85.4%) (P=0.31). At the end of therapy, the final clinical success rate in CA group (91.7%) was similar to that in CT group (100%) (P=0.15). In 18 patients, with microbiologically defined infections, the eradication rate was 100% in both groups. Adverse events including liver dysfunction (21.3%) and renal dysfunction (2.2%), were similar in both groups (P=0.87). Viridans streptococci were isolated from the throat cultures in 25 cases, and all of these strains were susceptible to penicillin (MIC(90)0.12 microgram/mL), cefepime (1 microgram/mL), and vancomycin (0.12 microgram/mL). CONCLUSION: Efficacy and safety of cefepime monotherapy was comparable to the combination of ceftazidime and tobramycin. It could be used as an alternative empirical regimen for treating cancer patients with febrile neutropenia.
