Evaluation of nasal patency by acoustic rhinometry after repair of complete unilateral cleft lip and palate.

PURPOSE: The aim of the current study was to evaluate nasal patency by acoustic rhinometry in children aged 4-8 years with repaired complete unilateral cleft lip and palate (UCLP) compared with an age-matched control group without cleft lip and palate (CLP). METHODS: This comparative cross-sectional study was conducted at a tertiary care teaching hospital and a private ENT clinic in Porto Alegre, southern Brazil. The case group consisted of 38 children who had undergone surgery for complete UCLP (mean age, 6.44 years), and the control group of 21 children without CLP (mean age, 6.21 years) recruited among patients seeking medical care for ear diseases at the private clinic. Acoustic rhinometry was performed in all children after administration of oxymetazoline hydrochloride (2 × 0.25 mg/mL) for nasal vasoconstriction. RESULTS: The minimal cross-sectional area and nasal volume of the cleft side were smaller than those of the non-cleft side in the case group (p = 0.001). When the two groups were compared, the non-cleft side in the case group did not differ from the control group (p = 0.175), but the minimal cross-sectional area and volume of the cleft nasal cavity were smaller than the mean values of the two nostrils of controls (p = 0.001). CONCLUSION: In conclusion, our findings show that nasal patency on the cleft side is impaired in children surgically treated for complete UCLP.

Sources of processed lipoaspirate cells: influence of donor site on cell concentration.

BACKGROUND: Recently, adipose tissue harvested by liposuction has been identified as a source of processed lipoaspirate cells. The aim of this study was to determine the concentration of processed lipoaspirate cells in adipose tissue obtained by liposuction from different harvest areas in women. METHODS: A prospective cross-sectional study was conducted in 25 women in whom liposuction in four or more different zones in the same procedure was indicated. After selective liposuction, the material was sent to the laboratory, where it was processed for extraction of processed lipoaspirate cells, which were separated from the adipose tissue, quantified, and characterized through determination of c-kit expression. The following harvest regions were evaluated: upper abdomen, lower abdomen, trochanteric region, inner thigh, knee, and flank. The cell concentration obtained at each site was compared by analysis of variance for mixed models. RESULTS: A significant difference was found for cell concentration obtained at the different harvest sites. The cell concentration in the lower abdomen was greater than in other areas, but no significant difference was found in relation to the inner thigh. CONCLUSIONS: The lower abdomen and the inner thigh may have higher processed lipoaspirate cell concentrations. These sites may turn out to be better sources of adult mesenchymal stem cells.

Estatística de atendimento no serviço de cirurgia plástica do complexo hospitalar Santa Casa de Porto Alegre / Statistics of plastic surgery service of Santa Casa hospital complex of Porto Alegre

Atualmente, uma importante atenção tem sido dispensada para o controle hospitalar dos recursos financeiros e humanos envolvidos na atenção à saúde. A quantificação correta do tipo de assistência que é dispensado para uma determinada população é uma fer- ramenta indispensável quando uma instituição planeja ter um melhor gerenciamento de sua prestação de ser- viços. Através destas estatísticas os recursos financeiros e humanos poderão ser usados mais racionalmente. Este artigo mostra as estatísticas, de um serviço de cirurgia plástica, em um hospital geral, e discute como os registros médicos podem produzir mudanças na tomada de decisões.

Actually an important attention have been directed for the hospitalar control of the finnancial resources and manpower involved in health care. The correct quantification of the kind of assistance that is dispended to a specific population is an indispensable tool when an institution plan to have a better management of their prested work. By this statistics the finnancial resources and manpower can have a more racionable use. This article shows the statistics of a plastic surgery service in a general hospital and discuss how medical records can make changes in the decision making.

Síndrome de Mirizzi e fístula colecistobiliar / Mirizzi syndrome and cholecystobiliar fistula

A Síndrome de Mirizzi é uma entidade rara, definida como uma obstrução do ducto hepático comum, secundária à compressão externa causada por cálculos impactados no infundíbulo da vesícula biliar ou no ducto cístico. O objetivo deste trabalho é revisar os critérios diagnósticos, classificação e tratamentos propostos para essa síndrome
