The use of 70 patients of functionally active drainage in combination with the developed method for sanation of the abdominal cavity permitted to decrease lethality in diffuse peritonitis by 10% when compared with the existing methods for drainage of the abdominal cavity, to shorten the duration of treatment of the patients. 相似文献

26 placentas of Kirghiz women from the town of Narin situated at the altitude of 2020 m above the sea level (moderate altitude), 22 placentas of women from Murgab (3600-3800 m above the sea level, high altitude) and 22 placentas of Frunze city (760 m, control) women were studied by means of organo--and stereometry using a standardized schema. A body weight decrease of newborns and placentas was established in the rating: control--moderate--high altitude. "Miniaturization" of foetuses is a response to the natural deficiency of oxygen in the atmospheric air. Moderate hypoxia has a training effect on the placenta while hypoxia associated with high altitude is followed by its dysadaptation. The role of placenta in the mechanisms of the foetus development inhibition under the conditions of natural hypoxia is suggested. 相似文献

Evidence-based medicine is practised widely in some specialties and is now part of many undergraduate and graduate medical curricula. However, the extent to which it is used in clinical paediatric practice is not known and its expansion remains a major challenge. Access to technology which facilitates literature searching, and development of journals addressing specific paediatric problems, will encourage the use of evidence-based medicine by the busy paediatrician. Informed practice of evidence-based medicine will ensure that clinical expertise is complemented by a thorough search, evaluation and judicious application of relevant information from the medical literature. 相似文献

Cleft sternum is a rare congenital defect of the anterior chest wall and is the result of a failed midline fusion of the sternum. Depending on the degree of separation, there are complete and incomplete forms. Its clinical significance is that it leaves the heart and great vessels unprotected. Association with craniofacial hemangiomas and omphalocele is common. Prenatal diagnosis by ultrasonography is possible. Surgical correction should be performed during the neonatal period when the direct suturing of the sternal halves is possible and the thorax can accommodate the thoracic viscera. At an older age, surgical repair is feasible, but it may require additional measures, such as sliding chondrotomies of the adjacent costal cartilages and notching of the sternal bars, to facilitate the approximation. Lung herniation at the base of the neck should be corrected by uniting the cervical muscles. The first postoperative day is the most critical because of acute reduction of the mediastinal space. Long-term results are satisfactory. Sternal foramen is a congenital oval defect at the lower third of the sternum that is asymptomatic and could be detected by CT scanning. The awareness of the anomaly is important in acupuncture practice because of the danger of heart damage. 相似文献

Nineteen infants who were graduates from special care baby units underwent two overnight tape recordings of oxygen saturation (SaO2) and breathing movements; one during an upper (n = 12) or lower (n = 7) respiratory tract infection and the other when free of infection. Baseline SaO2 was lower during infection (median 99.6 vs 100%, p less than 0.01), with four patients having values (84.3-95.5%) below the normal lower limit for full-term infants (97%). The median number of apnoeic pauses was also lower during respiratory tract infection (4.7 vs 15.7/h, p less than 0.02). The median number of episodic desaturations (SaO2 less than or equal to 80%) did not change significantly (1.3 vs 1.9/h, p greater than 0.05), with the exception of one patient who had extremely increased values during infection for both apnoeic pauses (63/h) and desaturations (112/h). No infant, however, was considered clinically hypoxaemic. Clinically unsuspected hypoxaemia may thus occur during respiratory tract infection in a proportion of infants graduating from special care baby units. Such hypoxaemia may have potentially deleterious effects. 相似文献

Endoscopic management of postoperative bile leak 总被引:14,自引:0,他引:14

Significant bile leak is an uncommon but serious complication of biliary tract surgery. Of twenty-five patients presenting with postoperative bile leak, 11 had complete tie-off of common bile duct and required surgery, while the remaining 14 had injury without complete obstruction and could be managed by endoscopic methods. Of these 14 cases, bile leak occurred from the cystic duct in 11 patients and from the common hepatic duct, right hepatic duct and left hepatic duct in one patient each. Endoscopic procedures performed included sphincterotomy alone (four patients), sphincterotomy and stent placement (seven patients) and sphincterotomy followed by nasobiliary catheter drainage (three patients). There was no technical failure and bile leak was stopped in all patients. One patient died of haemobilia 5 days after stent placement. When technically feasible, postoperative bile leak can be managed safely and effectively by endoscopic methods, obviating the need for surgical reexploration. 相似文献

The monoclonal antibody 5B5 reacts with the beta subunit of proline-4-
hydroxylase, the enzyme which catalyses the formation of 4-hydroxyl proline
in collagen and other proteins with collagen-like amino acid sequences.
This study aims to assess the production and tissue distribution of this
enzyme in normal and diseased synovia from patients with various joint
diseases, on the basis that it is a putative marker of collagen-producing
cells and, therefore, in this context, of fibroblasts. Sections from five
normal, 10 osteoarthritic (OA) and 26 rheumatoid arthritic (RA) synovia
were labelled with a mouse monoclonal antibody to proline-4-hydroxylase.
The enzyme was found to be expressed by a proportion of synovial intimal
cells and by fibroblasts in the underlying connective tissue in normal, OA
and RA synovia. Labelling was more pronounced in OA and RA cases. The
intimal cells labelling positively showed type B synoviocyte morphology,
which was confirmed by subsequent double immunolabelling with 5B5 and
antibody against type IV collagen using immunocytochemistry and
immunoelectron microscopy.

Endoscopic management of acute calculous cholangitis 总被引:16,自引:0,他引:16

Acute cholangitis is associated with significant morbidity and mortality. Endoscopic drainage procedures have been shown to be a safe and effective mode of treatment in acute cholangitis. As there is paucity of large series on endoscopic management of acute cholangitis, a study was performed to evaluate safety and efficiency of endoscopic biliary decompression in acute cholangitis. The study included 89 consecutive patients (mean age 55 ± 15 years; range 35–70 years; 50 males) with acute cholangitis requiring biliary drainage. Main presenting features were upper abdominal pain (84%), fever with chills (90%) and jaundice (74%). Altered sensorium, hypotension, features of peritonitis and acute renal failure were present in 15, 11, 18 and 5%, respectively. Endoscopic procedures performed were endoscopic sphincterotomy (ES) with stone extraction (n= 40); ES with endoscopic nasobiliary drainage (ENBD; n= 30); ENBD without ES (n= 8); and ES with stent placement (n= 11). Of the 89 patients, 85 (95%) responded within 48–72 h. Endoscopic common duct clearance could be achieved in 58 of 78 (74%) patients, whereas in 11 patients undergoing stent placement, stone extraction was not attempted. Complications included post-sphincterotomy bleed (n= 2), retroduodenal perforation (n= 1) and acute pancreatitis (n= 1) with an overall complication rate of 4.4%. All the complications were seen in patients undergoing ES with stone extraction. Mortality was 3.3%. In conclusion, endoscopic biliary drainage is a safe and effective mode of treatment for acute cholangitis. Endoscopic nasobiliary drainage or stent placement is safer than ES in acute cholangitis as an initial step. 相似文献
