Twenty-eight symptomatic dural fistulas involving the transverse and sigmoid sinuses were treated between 1978 and 1986 with a variety of treatment modalities. Occipital artery compression therapy resulted in a complete cure in two of nine patients (22%) and improvement in three of nine (33%). There were no complications from this treatment. Patients who were excluded or in whom compression therapy failed were treated with embolization alone or in conjunction with surgery. Of the 17 patients who underwent embolization alone, ten were cured and six were improved. Six patients had a combination of embolization and surgery; four patients were cured and two improved. There were three complications in this series, one related to surgery and two related to embolization.  相似文献

Dysgonic fermenter type 2, a gram-negative bacillus that is part of the normal oral flora of dogs and cats, is responsible for increasing numbers of cases of fulminant septicemia in humans. Patients usually have preexisting medical illnesses, but infection also occurs in otherwise healthy individuals. Most infections are acquired through animal contact. Dermatologic eruptions occur in half of the patients with dysgonic fermenter type 2 infection, and include petechiae, purpura, cellulitis, and gangrene.  相似文献

AIDS/HIV Positivity has been the most widely debated disease of this century. Reasons for this are manifold, viz-the non-availability of cure and consequent 100% mortality of a full blown case; its mode of transmission-homosexual and heterosexual activities; widespread occurrence amongst ‘main liners’; and patients receiving blood and blood products etc. These aspects have created a dreaded halo around AIDS as well as social stigma. Even the medical community is not exempt from these problems. Unfortunately, legislatures around the world, more so in India, have lagged behind in clarifying many legal issues involved by not enacting specific laws pertaining to AIDS. Consequently many legal & ethical doubts arise in the minds of doctors when confronted with a case of AIDS either in a live patient or in a dead body. In addition, the disease being incurable & 100% fatal, makes it essential to adopt effective preventive measures which in turn need thorough knowledge of social aspects of the epidemic. Certain medicolegal, and ethical aspects of the problem of AIDS are recapitulated in this article for the benefit of the medical community.KEY WORDS: Access, AIDS, Confidentiality  相似文献

Small cell lung cancer (SCLC) is known for its metastatic potential. The most common sites are liver, adrenal, bone and brain. We report a case of a 37 year old female patient, diagnosed with SCLC, presenting with gingival metastasis, an unusual metastatic site. Radiation therapy to the metastatic lesion to a dose of 20 Gray in 5 fractions over 5 days was delivered which achieved haemostasis and good palliation. However, the patient expired in 2 months owing to systemic metastasis.  相似文献

The ER-/PR+ breast tumor may be the result of a false ER negative result. The aim of this study was to investigate whether there is a difference in patient and tumor characteristics of the ER-/PR+ phenotype in an Asian setting. A total of 2629 breast cancer patients were categorized on the basis of their age, ethnicity, tumor hormonal receptor phenotype, grade and histological type. There were 1230 (46.8%) ER+/PR+, 306 (11.6%) ER+/PR-, 122 (4.6%) ER-/PR+ and 972 (37%) ER-/PR-. ER-/PR+ tumors were 2.5 times more likely to be younger than 50 years at diagnosis (OR: 2.52; 95% CI: 1.72-3.67). Compared to ER+/PR+ tumors, the ER-/ PR+ phenotype was twice more likely to be associated with grade 3 tumors (OR:2.02; 95%CI: 1.00-4.10). In contrast, compared to ER-/PR- tumors, the ER-/PR+ phenotype was 90% less likely to be associated with a grade 3 tumor (OR: 0.12; 95%CI:0.05-0.26), and more likely to have invasive lobular than invasive ductal histology (OR: 3.66; 95%CI: 1.47-9.11). These results show that the ER-/PR+ phenotype occurs in a younger age group and is associated with intermediate histopathological characteristics compared to ER+/PR+ and ER-/PR- tumors. This may imply that it is a distinct entity and not a technical artifact.  相似文献

Of 62 patients (mean age 75, range 65-92 years) referred to an out-patient anticoagulant clinic specifically for those aged 65 years or more, treatment was considered unsafe in only one patient and was discontinued. Minor bleeding which did not require a significant change in management was recorded on 25 (7%) of 381 clinic visits and one major haemorrhage occurred requiring emergency hospital admission. Anticoagulation was maintained within the therapeutic range on 284 (75%) visits. The results confirm that with appropriate out-patient care and supervision, the risks of oral anticoagulant therapy in the elderly need be no greater than in younger patients.  相似文献

Changing presentation of myocardial infarction with increasing old age   总被引:10,自引:0,他引:10  
The symptoms associated with acute myocardial infarction in a series of 777 elderly hospitalized patients are reviewed. Their ages ranged from 65 to 100, with a mean of 76.0 years. The spectrum of presentation changed significantly with increasing age. Chest pain or discomfort were less frequently reported, although present in the majority of patients up to 85 years. Syncope, stroke, and acute confusion became more common and were often the sole presenting symptom. Shortness of breath, although the most frequently reported symptom in the absence of chest pain, was equally common at all ages. Thus, in patients aged 85 years or over, "atypical" presentation of myocardial infarction became the rule, and in the very old the clinician must be prepared to screen for the diagnosis in most acutely ill patients.  相似文献

Use of phototherapy for hyperbilirubinaemia in 300 consecutively treated infants has shown that minor complications are common. With a knowledge of these complications and measures taken to minimize their effects, phototherapy appears to be safe in the short term. The long-term follow-up study showed that growth, and in particular head circumference, was not affected. There was, however, a higher incidence of squints and abnormal developmental performance in those infants treated with phototherapy. This may not have been due to phototherapy usage per se. However, because of these findings, it is suggested that phototherapy should not be used indiscriminately for hyperbilirubinaemia until the results of further long-term studies are available.  相似文献
