Effectiveness of balloon sinuplasty in patients with chronic rhinosinusitis without polyposis.

INTRODUCTION: Balloon sinuplasty is a minimally invasive endoscopic procedure, developed with the aim of restoring patency of the paranasal sinuses ostia with minimal damage to the mucosa. OBJECTIVE: To evaluate the effectiveness of balloon sinuplasty in patients with chronic rhinosinusitis. METHODS: This was a prospective cohort study comprising 18 patients with chronic rhinosinusitis without polyposis who underwent balloon sinuplasty. Patients were evaluated for clinical criteria, quality of life (Sino-Nasal Outcome Questionnaire Test-20 [SNOT-20]), and computed tomography of the sinuses (Lund-Mackay staging) preoperatively and three to six months after the procedure. RESULTS: Out of 18 patients assessed, 13 were included, with a mean age of 39.9±15.6 years. Ostia sinuplasty was performed in 24 ostia (four sphenoid, ten frontal, and ten maxillary sinus). At the follow-up, 22 (92%) ostia were patent and there was no major complication. There was symptomatic improvement (SNOT-20), with Cronbach coefficients for consistency of the questionnaire items of 0.86 (95% CI: 0.73-0.94) preoperatively and of 0.88 (95% CI: 0.77-0.95) postoperatively, the difference being statistically significant (p<0.001). In addition, there was marked reduction of the computed tomography signs, an average of 4.2 point score (p<0.001). CONCLUSION: Sinuplasty is effective in reducing symptoms and improving quality of life as a treatment option for chronic rhinosinusitis in selected patients.

The impact of acute loss of weight on eustachian tube function.

Introduction The eustachian tube is one of the key structures responsible for the functional balance of the middle ear. Some clinical conditions associated with tubal malfunction can cause extremely unpleasant symptoms. These symptoms could be triggered by acute loss of weight, for example, after bariatric surgery. Objective To evaluate the frequency and intensity of auditory tube dysfunction symptoms in obese patients after bariatric surgery. Methods Nineteen patients with accepted formal indications for bariatric surgery underwent a hearing evaluation (otoscopy, tonal and vocal audiometry, and impedanceometry) and a hearing questionnaire before, at the time of, 3 months after surgery (first postoperative evaluation), and 6 months (second postoperative evaluation) after surgery. Patients with a history of ear disease or ear surgery were excluded. Results None of the patients reported tubal dysfunction symptoms before surgery. Postsurgical results showed that 5 (26.3%) patients presented symptoms related to dysfunction of the eustachian tube at the first postoperative evaluation. After the 6-month follow-up, 9 (47.3%) patients reported symptoms of tubal dysfunction. Conclusion This study suggests that bariatric surgery can cause symptoms of eustachian tube dysfunction, probably due to rapid weight loss and the consequent loss of peritubal fat.

Plasmacytoid dendritic cells are increased in cerebrospinal fluid of untreated patients during multiple sclerosis relapse.

The plasmacytoid dendritic cells (pDCs) express a high level of Toll-like receptor 9 (TLR-9), which recognizes viral DNA. Activated via TLR-9, pDCs also secrete large amounts of type I interferon which are involved either in stimulation or down regulation of immune response in multiple sclerosis (MS). In the present study, we determinate pDCs levels by flow cytometry in Cerebrospinal Fluid (CSF) and Peripheral Blood from MS patients in relapsing and in remitting phases of the disease, comparing with other non-inflammatory diseases (OND). We provide evidence that MS patients in relapse without any treatment have a significantly (p < 0.01) higher percentage of pDCs in CSF than do patients in remission or those with OND. No change in the percentage of pDCs was observed in the peripheral blood of any of these patients. The increase of pDCs in central nervous system during relapse may be explained either by a virus infection or a down regulatory process.

Características reprodutivas de veado-bororó-do-sul ou veado-mão-curta (Mazama nana) / Reproductive characteristics of Brazilian dwarf brocket deer (Mazama nana)

Dos cervídeos brasileiros, a espécie Mazama nana é a menos conhecida. Os parâmetros reprodutivos para os machos ainda são desconhecidos, mas parece que não apresentam sazonalidade reprodutiva. Neste trabalho foram utilizados nove machos de Mazama nana em idade reprodutiva, mantidos em cativeiro. Foram avaliados quanto ao peso corporal, altura de cernelha, comprimento crânio-caudal, situação dos chifres, volume e consistência testicular. O sêmen foi colhido por eletroejaculação e submetido a análises de motilidade, vigor e morfologia espermática. As correlações entre idade, peso, comprimento crânio-caudal, altura de cernelha, volume testicular e características do ejaculado (volume, motilidade, vigor e concentração do sêmen) foram avaliadas pelo procedimento Corr., do SAS®. As médias ± desvio padrão observados para peso (kg), comprimento crânio-caudal (cm) e altura de cernelha (cm) foram: 15,72±1,98, 74,9±3,05 e 48,5±2,06, respectivamente. Em relação aos parâmetros reprodutivos primários foram observados: volume do ejaculado (91,46±68,24µl); motilidade (70±8,16 por cento); vigor (3,0±0,67); concentração espermática (1536x10(6) ±351x10(6) espermatozóides por ml). Em relação à morfologia espermática, foi observada uma alta porcentagem de células anormais (40,90 por cento), sendo predominante os defeitos de cauda (25,95 por cento).

Mazama nana is the least known of Brazilian deer species. The male reproductive parameters are still unknown, but apparently they did not show reproductive seasonality. In this work were used nine males of M. nana in reproductive age, kept in captivity. They were assessed for weight, height of wither, crown-rump length, the situation of horns, testicular volume and consistency. The sperm was collected by electro-ejaculation and subjected to analyses of motility, vigor and morphology. The correlation between age, weight, height of wither, crown-rump length, testicular volume and characteristics of the ejaculate (volume, motility, vigor and sperm concentration) were evaluated by the procedure Corr., of SAS®. The mean ± standard deviation observed for weight (kg), crown-rump length (cm) and height of wither (cm) were: 15.72±1.98, 74.9±3.05, and 48.5±2.06 respectively. For primary reproductive parameters were observed: volume of ejaculate (91.46±68.24ìl); motility (70±8.16 percent); vigor (3.0±0.67); sperm concentration (1536x10(6) ±351x10(6) spermatozoa per ml). For sperm morphology was found a high percentage of abnormal cells (40.90 percent), with predominant defects in the tail (25.95 percent).
