RESUMO

The goal of this prospective randomized clinical trial was to compare 2 cohorts of standardized cleft patients with regard to functional speech outcome and the presence or absence of palatal fistulae. The 2 cohorts are randomized to undergo either a conventional von Langenbeck repair with intravelar velarplasty or the double-opposing Z-plasty Furlow procedure. A prospective 2 × 2 × 2 factorial clinical trial was used in which each subject was randomly assigned to 1 of 8 different groups: 1 of 2 different lip repairs (Spina vs. Millard), 1 of 2 different palatal repair (von Langenbeck vs. Furlow), and 1 of 2 different ages at time of palatal surgery (9-12 months vs. 15-18 months). All surgeries were performed by the same 4 surgeons. A cul-de-sac test of hypernasality and a mirror test of nasal air emission were selected as primary outcome measures for velopharyngeal function. Both a surgeon and speech pathologist examined patients for the presence of palatal fistulae. In this study, the Furlow double-opposing Z-palatoplasty resulted in significantly better velopharyngeal function for speech than the von Langenbeck procedure as determined by the perceptual cul-de-sac test of hypernasality. Fistula occurrence was significantly higher for the Furlow procedure than for the von Langenbeck. Fistulas were more likely to occur in patients with wider clefts and when relaxing incisions were not used.

RESUMO

OBJECTIVE: Cleft palate increases the risk of chronic middle ear disease and hearing loss. The goal of this report was to determine which of two palate surgeries and which timing of palate surgery were associated with better otologic and audiologic outcomes in children with unilateral cleft lip and palate at 5 to 6 years of age. DESIGN: Subjects were randomly assigned to the von Langenbeck with intravelar veloplasty or Furlow palate repair, to palate surgery at 9 to 12 months or 15 to 18 months of age, and to the Spina or Millard lip repair. SETTING: Centralized, tertiary care craniofacial treatment center. PATIENTS: A total of 673 infants with unilateral cleft lip and palate. INTERVENTIONS: Palate and lip were repaired using established techniques. Serial otoscopic and audiometric evaluations were performed. MAIN OUTCOME MEASURES: Hearing and otoscopic findings at 5 to 6 years old. RESULTS: There were 370 children available for analysis. Hearing and need for tympanostomy tube placement did not differ by palatoplasty, age at palatoplasty, cheiloplasty, or surgeon. Risk of developing cholesteatoma or perforation was higher with Millard cheiloplasty (odds ratio  =  5.1, 95% confidence interval  =  1.44 to 18.11, p  =  .012). Type and age at palatoplasty were not significantly associated with either the rate of developing these sequelae or the rate of achieving bilaterally normal hearing and ear examinations. CONCLUSIONS: Type of palatoplasty did not influence otologic and audiologic outcomes in 5- to 6-year-olds with unilateral cleft lip and palate. The potential influence of lip repair on otologic outcomes warrants further investigation.

RESUMO

Sepsis remains the most important cause of acute kidney injury (AKI) in critically ill patients and is an independent predictor of poor outcome. The administration of lipopolysaccharide (LPS) to animals reproduces most of the clinical features of sepsis, including AKI, a condition associated with renal cellular dysfunction and apoptosis. Erythropoietin (EPO) is a well known cytoprotective multifunctional hormone, which exerts anti-inflammatory, anti-oxidant, anti-apoptotic and angiogenic effects in several tissues. The aim of this study was to evaluate the underlying mechanisms of EPO renoprotection through the expression of the EPO receptor (EPO-R) and the modulation of the intrinsic apoptotic pathway in LPS-induced AKI. Male inbred Balb/c mice were divided in four experimental groups: Control, LPS (8 mg/kg i.p.), EPO (3000 IU sc) and LPS+EPO. Assessment of renal function, histological examination, TUNEL in situ assay, immunohistochemistry and Western blottings of caspase-3, Bax, Bcl-xL, EPO-R and Cytochrome c were performed at 24h post treatment. LPS+EPO treatment significantly improved renal function and ameliorated histopathological injury when compared to the LPS treated group. Results showed that EPO treatment attenuates renal tubular apoptosis through: (a) the overexpression of EPO-R in tubular interstitial cells, (b) the reduction of Bax/Bcl-xL ratio, (c) the inhibition Cytochrome c release into the cytosol and (d) the decrease of the active caspase-3 expression. This study suggests that EPO exerts renoprotection on an experimental model of LPS-induced AKI. EPO induced renoprotection involves an anti-apoptotic effect through the expression of EPO-R and the regulation of the mitochondrial apoptotic pathway.

RESUMO

OBJECTIVE: To study the growth of children with complete unilateral cleft lip and palate (UCLP) from birth to 2 years of age and to construct specific UCLP growth curves. DESIGN: Physical growth was a secondary outcome measure of a National Institutes of Health-sponsored longitudinal, prospective clinical trial involving the University of Florida (United States) and the University of São Paulo (Brazil). PATIENTS: Six hundred twenty-seven children with UCLP, nonsyndromic, both genders. METHODS: Length, weight, and head circumference were prospectively measured for a group of children enrolled in a clinical trial. Median growth curves for the three parameters (length, weight, head circumference) were performed and compared with the median for the National Center for Health Statistics (NCHS) curves. The median values for length, weight, and head circumference at birth and 6, 12, 18, and 24 months of age were plotted against NCHS median values and statistically compared at birth and 24 months. SETTING: Hospital de Reabilitação de Anomalias Craniofaciais, Universidade de São Paulo, Bauru, Brazil (HRAC-USP). RESULTS: At birth, children of both genders with UCLP presented with smaller body dimensions in relation to NCHS median values, but the results suggest a catch-up growth for length, weight, and head circumference for girls and for weight (to some degree) and head circumference for boys. CONCLUSIONS: Weight was the most compromised parameter for both genders, followed by length and then head circumference. There was no evidence of short stature. This study established growth curves for children with UCLP.
