One hundred and thirty right and 114 left first ribs from a random collection have been studied for the characters of the scalene tubercle and the related structures. The tubercle is not always present but the muscular impression for the insertion of the scalenus anterior muscle on the superior surface of the first rib is almost constant and it generally extends upto the medial third of this surface. The arterial groove, generally shallow, lies behind the tubercle or the muscular impression and generally extends only upto the medial 2/3 of the superior surface. Likewise, the venous groove, mostly shallow, lies in front of the tubercle or the muscular impression and extends, generally, only upto the medial 2/3 of the surface. Normally, there is no separate groove for the lower trunk of the brachial plexus. 相似文献

Background
Lymph node infarction is known to occur in association with many non-neoplastic and neoplastic conditions however its occurrence in association with DIC is not reported hitherto in the literature. 相似文献3.

Endoscopic biopsies obtained from 275 patients (180 from the upper gastrointestinal tract and 95 from the lower gastrointestinal tract) were studied to compare the accuracy of biopsy imprint cytology and histology in the diagnosis of gastrointestinal lesions, and also to establish the degree of reliability of imprint cytology alone for an early diagnosis of malignancy. Biopsy histology results were found to be correct in 100% cases. Imprint cytology had an overall accuracy of 100%, 96.7%, 95.8% and 95.8% for the diagnosis of malignancies of the oesophagus, stomach, duodenum and colorectum respectively. False negative results were obtained with lymphomas. Regenerative cellular atypia was an important cause for false positive results. It was concluded that imprint cytology can serve as a useful and simple tool for an immediate diagnosis of malignancy. This should be subsequently correlated with histopathology which facilitates exact tumour typing and assessment of tumour invasion. 相似文献

The molecular characterization of the mutations in hemophilia A patients is hampered by the large size of the factor VIII gene and the great heterogeneity of mutations. In this study, we have performed a protocol involving multiplex polymerase chain reaction in which 19 exons were amplified in four different combinations followed by nonradioactive single-strand conformational polymorphism (SSCP) to screen for mutations. Southern blotting was used to detect inversion of the factor VIII gene resulting from recombination between copies of the gene A (F8A) located in intron 22 of the factor VIII gene and two copies close telomeric region of X chromosome. Forty-two hemophilia A patients (21 with severe and 21 with mild-to-moderate disease) were studied. The inversion of factor VIII occurred in 13 of 21 patients affected by severe hemophilia A. One patient showed a large extra band in addition to the three bands observed after Southern blotting with the F8A probe. An abnormal electrophoretic pattern of SSCP was detected in 85% and 50% of the patients affected by mild-to-moderate and severe disease, respectively. Sixteen different mutations were identified. Eleven mutations were novel and comprised 9 point mutations and 2 small deletions. This study shows that the methodology used is safe and rapid and has potential for detecting almost all of the genetic defects of the studied hemophilia A patients. 相似文献

Background: Optimum pain relief following thoracotomy is essential for patient comfort and to reduce the incidence of postoperative pulmonary
complications.
Methods: A randomized clinical trial was conducted on 90 patients scheduled for pulmonary resection. The patients were randomly divided
into three groups. Group 1 received 0.125% bupivicaine with fentanyl 10μg.ml−1, Group 2 received 0.25% bupivicaine with fentanyl 10μg.ml−1 and Group 3 received only fentanyl 10μg.ml−1 in a calculated dose as a continuous thoracic epidural infusion. Adequacy of anglesia was assessed at rest and during movement
over 24 hours. Analgesic efficacy was assessed using a visual analogue score and an observer verbal ranking scale.
Results: Pain scores were significantly higher in Group 3 during the assessment period. (p<0.01) as compared to the other groups.
The use of intraoperative vasopressors was significantly higher (p<0.05) in Group 2 as compared to the other groups. No neurological
complications were encountered in any of the study groups.
Conclusion: We conclude that in the early postoperative period, the use of 0.125% bupivicaine improves fentanyl epidural analgesia in
patients undergoing lung resection. 相似文献

With increased access to HIV treatment throughout Africa, a generation of HIV positive children is now transitioning to adulthood while living with a chronic condition requiring lifelong medication, which can amplify the anxieties of adolescence. This qualitative study explored how adolescents in Tanzania with HIV experience their nascent sexuality, as part of an evaluation of a home-based care programme. We interviewed 14 adolescents aged 15–19 who had acquired HIV perinatally, 10 of their parents or other primary caregivers, and 12 volunteer home-based care providers who provided support, practical advice, and referrals to clinical services. Adolescents expressed unease about their sexuality, fearing that sex and relationships were inappropriate and hazardous, given their HIV status. They worried about having to disclose their status to partners, the risks of infecting others and for their own health. Thus, many anticipated postponing or avoiding sex indefinitely. Caregivers and home-based care providers reinforced negative views of sexual activity, partly due to prevailing misconceptions about the harmful effects of sex with HIV. The adolescents had restricted access to accurate information, appropriate guidance, or comprehensive reproductive health services and were likely to experience significant unmet need as they initiated sexual relationships. Care programmes could help to reduce this gap by facilitating open communication about sexuality between adolescents and their caregivers, providers, and HIV-positive peers. 相似文献
