Objectives/Hypothesis: To evaluate the role of inferior turbinate reduction during rhinoseptoplasty in quality-of-life outcomes and nasal airway cross-sectional area. Study Design: Randomized clinical trial. Methods: Individuals over 16 years with nasal obstruction, candidates to functional and aesthetics primary rhinoseptoplasty, were evaluated from December 2010 though January 2012 at a tertiary University Hospital, Brazil. Eligible participants were randomly allocated to rhinoseptoplasty with or inferior turbinate reduction through submucosal diathermy. Outcomes: Relative changes ([postop-preop]/preop score) in specific (Nasal Obstruction Symptom Evaluation; NOSE) and general quality-of-life instruments (WHOQOL-bref), nasal obstruction visual analogue scale (NO-VAS) and nasal area measurements in acoustic rhinometry. Outcomes were blindly assessed 3 months postoperatively. Protocol was registered at ClinicalTrials.gov (NCT01457638). Results: 50 patients were included, mainly Caucasians with moderate/severe allergic rhinitis symptoms. Mean age was 32 ± 12 yr and 58% were female. Rhinoseptoplasty improved specific and general quality-of-life scores irrespective of turbinate intervention (P < 0.001).There was no difference between subjects submitted or not to inferior turbinate reduction in NOSE score (-75% vs. -73%; P = 0.893); all WHOQOL-bref score domains (P > 0.05), NO-VAS (-88% vs. -81%; P = 0.89) and acoustic rhinometry recordings (P > 0.05).During follow-up less patients in the rhinoplasty with inferior turbinate reduction group were using topical corticosteroids (6[24%] vs. 13[54%]; P = 0.03). Multivariable analyses, adjusting for postoperative topical corticosteroid use and previous nasal fracture, had no effect on these results. Conclusions: Turbinate reduction through submucosal diathermy during primary rhinoseptoplasty did not improve short-term general and specific quality-of-life outcomes and acoustic rhinometry recordings. The role of turbinate reduction in sparing chronic corticosteroid use should be confirmed in long-term follow-up studies.

Background Renal transplant patients have a higher incidence of non-melanoma skin cancer (NMSC). Previous studies hypothesized that human leukocyte antigen (HLA), especially types DR1, DR4, and DR7, may influence the incidence of these tumors. This study investigates the association between NMSC and the presence of HLA DR1, DR4, and DR7 in renal transplant patients in southern Brazil. Methods In a historical cohort study, 1032 patients who underwent renal transplantation during the period from January 1993 to December 2006 were examined to identify occurrences of NMSC and HLA status prior to transplant. Results Of the 1032 patients examined, 59 (5.71%) developed NMSC (squamous cell carcinoma [SCC]: 2.42%; basal cell carcinoma [BCC]: 1.74%; both: 1.55%). The presence of HLA DR1 was associated with a higher probability of developing any NMSC and particularly with developing BCC (P<0.05). There was no statistically significant association between the presence of HLA DR4 or DR7 and the occurrence of NMSC in this sample. Conclusions HLA DR1 appears to be associated with the development of BCC, as well as with the higher number of NMSC lesions in renal transplant patients. This study supports the trend to associate the DR1 allele with BCC and not with SCC. © 2012 The International Society of Dermatology.

Background: There is comparatively little information in the public domain on the diversity in prevalence and triggers/factors associated with allergic rhinitis (AR) or allergic rhinoconjunctivitis (AR/C) in countries beyond western-Europe and North America. Objective: To review the prevalence and the sensitizing agents/triggers and factors associated with AR/C in several countries in Africa, the Asia-Pacific region, Australia, Eastern Europe, Latin America, Middle East and Turkey. Methods: Articles published in English in peer-reviewed journals were assessed and selected for further review, following an extensive literature search using the Medline database. Results: This review demonstrated that prevalence of AR and AR/C in these regions has predominantly been investigated in children; with studies indicating wide inter- and intra-regional variations ranging from 2.9% AR and 3.8% AR/C in 10-18-years-old children from one region in Turkey to 54.1% AR and 39.2% AR/C in 13-14-years-old children in one region in Nigeria. Moreover, the prevalence of AR and AR/C has increased markedly over the last decade particularly in some of the more affluent African countries, China-Taiwan and several Middle East countries, likely as a consequence of improved living standards leading to increased exposure to multiple traditional and non-traditional sensitizing agents and risk factors similar to those noted in western-Europe and North America. Conclusions and Clinical Relevance: Our findings suggest that the greater diversity in prevalence of AR or AR/C in populations in these regions is in contrast to the lower diversity of AR or AR/C in the 'western populations (USA and Europe), which tend to be more uniform. This review provides a comprehensive database of the important allergens and triggers which are likely to influence the prevalence of allergic rhinitis in these diverse regions, where the prevalence of allergic rhinitis is increasing and its adverse impact on the quality of life of affected individuals is increasingly recognised. © 2011 Blackwell Publishing Ltd.

Hypothesis: Anomaly in the incudostapedial articulation (IS) may be responsible for persistent conductive hearing loss (HL) in Down's syndrome (DS) patients. Our goal was to perform a detailed histopathologic assessment of the role of the IS joint in the conductive HL. Background: In addition to other disabilities, 38% to 78% of patients with Down's syndrome (Trisomy 21) have CHL, some of which are persistent despite maximum treatment. The cause of the persistent conductive HL remains unclear. Methods: Retrospective analysis of temporal bone histopathology. Analyses of the midsection through the IS joint of 21 temporal bones (13 subjects) patients with DS and 31 temporal bones (18 subjects) from healthy subjects, performed by 2 blinded authors. The length of 7 different parameters of the width of the IS joint was measured and compared between the 2 groups. Results: The IS joint of patients with DS was significantly wider than the normal control. As opposed to the control, it did not decrease because of age. Conclusion: The persistent conductive HL in some patients with DS might be caused by anomaly of the IS joint. In severe cases, corrective surgery should be considered.

Introduction: Histoplasmosis is a systemic mycosis endemic in Brazil, especially in the State of Rio Grande do Sul, where Histoplasma capsulatum was isolated from the soil. H. capsulatum may compromise unusual areas, including the oropharynx, particularly in patients presenting disseminated histoplasmosis; which is associated with a state of immunosuppression, such as AIDS. Methods: During database analysis of a total of 265 cases of histoplasmosis, the medical records of 11 patients with histological or microbiological diagnoses of oral histoplasmosis (OH) between 1987 and 2008 were retrospectively reviewed. Results: Tis work reports 11 cases of OH, the majority presenting histopathological or microbiological evidence of disseminated histoplasmosis (DH). In the patients with DH, OH was the first manifestation of histoplasmosis. Five of the 11 patients discussed were HIV-seropositive with clinical and laboratory findings of AIDS. Four patients presented active pulmonary tuberculosis concomitant with histoplasmosis. Treatment was based on the use of itraconazole and amphotericin B deoxycholate. Eight patients responded successfully to therapy after one year, two did not come back for reevaluation and one died despite adequate therapy. Conclusions: Oral histoplasmosis is closely associated with immunosuppression status, especially in patients presenting AIDS; moreover, in many cases, OH is the first sign of disseminated histoplasmosis.
