The use of the CSFs in patients with established FN caused by cancer chemotherapy reduces the amount of time spent in hospital and the neutrophil recovery period. The possible influence of the CSFs on infection-related mortality requires further investigation.

São apresentadas, nessa separata, as principais orientações sobre a atenção às complicações do pé diabético. A neuropatia, com suas diversas apresentações que acometem os membros inferiores dos diabéticos, as lesões da doença arterial obstrutiva periférica (DAOP), as múltiplas apresentações da infecção do pé diabético, e, principalmente, os cuidados preventivos que possam impedir o estabelecimento ou a evolução dessas complicações são tratados de forma sistemática e simplificada, visando a atenção integral desses doentes. Especial cuidado é dado às orientações diferenciadas para os diversos níveis de atenção nos serviços públicos de saúde, porta de entrada virtual de 80% dos infelizes portadores dessa complicação. São aqui apresentados modelos de atenção e sugeridos protocolos que podem contribuir para a efetiva redução do número de amputações, internações e óbitos de diabéticos com complicações nos membros inferiores

The evidence found was insufficient to demonstrate superiority of the stapling method over handsewing, independent of the level of colorectal anastomosis.

Theophylline has a modest effect on FEV1 and FVC and slightly improves arterial blood gas tensions in moderate to severe COPD. These benefits were seen in patients receiving a variety of different concomitant therapies. Improvement in exercise performance depended on the method of testing. There was a very low dropout rate in the studies that could be included in this review, which suggests that recruited patients may have been known by the investigators to be theophylline tolerant. This may limit the generalisability of these studies.

There is no evidence in the literature for beneficial effects from the use of bowel cleansing before elective colorectal surgery. Cleansing seems to be associated with an increased risk of more anastomotic dehiscence. Further studies stratifying between rectal and colonic surgery are warranted.

The importance of cryptorchidism treatment concerns the possibility of diminishing risk of malignant degeneration and improving fertility. Success rates of hormonal treatment vary: 0-55% with human chorionic gonadotropin (hCG) and 9-78% with gonadotropin-releasing hormone (GnRH). Due to uncertainties regarding the effectiveness of this treatment, a systematic review and meta-analysis of randomized controlled trials (RCTs) on hormonal cryptorchidism treatment was done using the methodology of Cochrane Collaboration. Two studies compared hCG with GnRH, with a testicular descent rate of 25% vs. 18%, respectively. Nine trials compared intranasal LHRH with placebo, with complete testicular descent rates of 19% vs. 5%. Two other studies comparing doses and administration intervals could not be pooled together due to heterogeneity. With the information analyzed until the present, the evidence for the use of hCG vs. GnRH shows advantages for hCG, and this review also shows that there is evidence that luteinizing hormone releasing hormone (LHRH) is more effective than placebo. But because this evidence is based on few trials, with small sample sizes and moderated risk of bias, this treatment cannot be recommended for everyone, and there is no evidence that supports hCG's use in larger doses and larger intervals. Results from this systematic review are important for developing better RCTs that may decrease the uncertainty of cryptorchidism treatment.

ResumoObjetivo: Determinar os fatores predisponentes para a amputação de membros inferiores nos doentes internados com diabetes melito e úlceras nos pés.Métodos: Foram acompanhados os pacientes diabéticos com úl-ceras nos pés internados no período de 6 meses e analisadas as amputações nesses doentes em relação à idade, sexo, amputação prévia, número de ulcerações, tempo de diagnóstico do diabete, tempo de ulceração, tempo médio de internação, gravidade das lesões, presença de pulso.Resultado: Verificou-se que 55% (44/80) dos doentes evoluíram para algum tipo de amputação de membros inferiores; a mediana das idades foi de 61 anos, porém a ocorrência de amputação foi significativamente maior na faixa etária dos 60 aos 90 anos (P = 0,03). Não se observou uma variação significativa da mediana do tempo de diagnóstico do diabetes, do tempo de ulceração e do tempo médio de internação em relação ao grupo de pacientes que foram amputados. Entretanto, as lesões mais graves, quando avaliadas pela classificação de Wagner (P < 0,001) e pela ausência de detecção dos dois pulsos distais (P < 0,001) dos membros inferiores, revelaram-se bastante significativas com relação ao desfecho de amputação.Conclusão: Foram considerados fatores predisponentes para a ocorrência de amputação nesses doentes a gravidade das lesões, a ausência de pulsos e as idades acima de 60 anos. Palavras-chave:Amputação, diabetes melito, pé diabético, úlcera. AbstractObjective: To determine the predisposing factors for amputation of lower limbs in diabetic patients with foot ulceration.Methods: The research was carried out in hospitals, and all diabetic patients with foot ulceration were included. Amputation was studied in relation to age, sex, previous amputation, number of ulcers, time of diagnosis of diabetes mellitus, time of ulceration, average number of days in hospital, Wagner's classification, and presence of foot pulse.Result: We verified that 55% (44/80) of the patients progressed to some type of amputation of the lower limbs; mean age was 61 years, but the occurrence of amputation was significantly higher in the age group between 60 and 90 years (P = 0.03). We did not observe a significant variation in the following variables: time of diagnosis of diabetes, time of ulceration, and hospitalization time in relation to the group of patients who were amputated. Nevertheless, the most severe lesions, when evaluated by Wagner's classification (P < 0.001) and by the absence of both distal pulses (P < 0.001) of lower limbs, turned out to be very significant in relation to the amputation outcome.Conclusion: The severity of lesions, the absence of pulse and age over 60 years were considered predisposing factors for amputation in these patients.
