Background
There are limited studies about optimal duration and benefits of breastfeeding—and in particular, exclusive breastfeeding—on infant health and growth in the occupied Palestinian territory. This study aimed to evaluate the effect of exclusive breastfeeding on the health of infants in the Gaza Strip (at age 9 months), in terms of anthropometric measurements, growth, and morbidity.Methods
This study targeted mothers with infants attending primary health centres for vaccination at 9 months of age. Eight primary health centres were randomly selected from United Nation for Relief and Work Agency and Ministry of Health primary health centres in four regions of the Gaza Strip. Of 343 mother–infant pairs, in the first 6 months of life 251 infants received mixed feeding and 92 were exclusively breastfed.Findings
There were significant differences between the head circumferences of infants who were exclusively breastfed and those who received mixed feeding (44·1 cm [SD 1·39] and 43·7 cm [SD 1·15], respectively; p=0·007). There were no significant differences in the length and weight of infants between the two groups. Infants who were exclusively breastfed had a significantly lower frequency of gastrointestinal infections than infants who received mixed feeding (48% and 80%, respectively; p=0·001), as well as greater protection against respiratory tract infection (47% and 83%, respectively; p=0·001), lower incidence of otitis media (18% and 38%, respectively), and a significantly lower risk of urinary tract infection (5% and 65% respectively; p=0·001).Interpretation
Human milk is unique, and breastfeeding is the healthiest practice for healthy term infants for approximately the first 6 months after birth, providing ideal nutrition and supporting optimal growth and development. It also provides reasonable protection against infectious diseases. Thus, breastfeeding is the reference model against which all alternative feeding methods must be measured, with respect to growth, and short-term and long-term health outcomes. Infants should be introduced to nutrient-rich, solid foods (with particular attention to iron) at 6 months, with continued breastfeeding for up to 2 years. Every effort should be made to maintain breastfeeding rather than using formula or other milk substitute.Funding

Spontaneous rupture of the spleen is a rare complication of chronic calcifying pancreatitis. Anemia and hemorrhagic shock may not occur, making diagnosis more difficult. Favourable response to conservative treatment does not prevent the need for splenectomy, as calcifiying chronic pancreatitis may progress locally. We report three cases of spontaneous rupture of the spleen. In two cases, splenic rupture revealed calcifying chronic pancreatitis and both patients underwent urgent splenectomy. In the third case, the patient was known to have calcifying chronic pancreatitis, and splenectomy was performed because of unsuccessful conservative treatment. We discuss the role of distal pancreatectomy during splenectomy to reduce the rate of postoperative complications and additional surgery. We also discuss the role of arterial embolisation and laparoscopy in the management of this rare condition. 相似文献

AIM: The aim of this study was to determine the safety and the efficacy of a gemcitabine/oxaliplatin combination (GEMOX) as first line therapy in patients with metastatic or unresectable locally-advanced pancreatic cancer. PATIENTS AND METHODS: Patients received gemcitabine 1000 mg/m2 as a 10-mg/m2/min infusion on day 1 followed on day 2 by oxaliplatin 100 mg/m2 as a 2-hour infusion, each cycle being given every 2 weeks. All patients had measurable disease and histological diagnosis before inclusion. Patients were treated until progression or for 12 cycles in the absence of progression. Tumor lesions were assessed by computed tomography scan every 4 cycles. RESULTS: Between January 2001 and January 2003, 32 patients were eligible for the study. The objective response rate (OR) was 28.1% with a 12.5% complete response rate (CR). Median progression-free survival and median overall survival were 7 and 9 months, respectively. Median overall survival for patients with metastatic disease and locally-advanced disease were 7 and 25 months, respectively (P < 0.0007). Eleven patients were alive at 1 year (34.4%), six at 2 years (18.8%) and two at 3 years (6%). Fourteen (43.8%) of 32 patients experienced a clinical benefit response. CONCLUSION: These results support the safety, the antitumor activity and the possibility of durable responses of the GEMOX regimen in patients with locally-advanced disease. 相似文献
