Mediterranean spotted fever (MSF) is caused by Rickettsia conorii, an obligate intracellular parasite of eukaryotic cells. Although, usually this disease has a benign course, a rapidly fatal outcome can occur even in young healthy adults. We describe a case of a 40-year-old Bedouin woman gravida 11, para 10, who was admitted at 36 weeks gestation with this rickettsial disease. During pregnancy, the treatment of choice for Mediterranean spotted fever is chloramphenicol, but it seems that Azithromycin could be another possible option. 相似文献

OBJECTIVE: The purpose of this study was to evaluate the effect of N-acetylcysteine on the activity and secretion of the matrix metalloproteinases in the decidua, amnion, and chorion and the secretion of the tissue inhibitor of matrix metalloproteinase-1. STUDY DESIGN: Samples from eight nonlaboring women were taken at elective cesarean section and incubated in an in vitro organ culture in the absence or presence of N-acetylcysteine. Matrix metalloproteinase-2 and matrix metalloproteinase-9 activity was measured with the use of gel zymography. Western blot analysis was used to measure matrix metalloproteinase and tissue inhibitor of matrix metalloproteinase-1 secretion. Data were analyzed with the paired Student t test. RESULTS: N-acetylcysteine had a direct inhibitory effect on matrix metalloproteinase-2 and matrix metalloproteinase-9 activity, regardless of tissue origin, starting at 1.0 mmol/L. In cultured media, 20 mmol/L N-acetylcysteine inhibited matrix metalloproteinase-2 and matrix metalloproteinase-9 activity in all three tissues. A differential response was demonstrated for matrix metalloproteinase-2 secretion, depending on the tissue that was studied. Its secretion was decreased in decidua at 10 mmol/L and 20 mmol/L; in amnion, the secretion was inhibited at 0.1 mmol/L and not affected at all in chorion. Matrix metalloproteinase-9 secretion was not affected in a statistically significant manner in any tissue. In the chorion, matrix metalloproteinase-9 showed a trend toward increased secretion. Tissue inhibitor of matrix metalloproteinase-1 secretion significantly decreased in the decidua at 20 mmol/L. CONCLUSION: N-acetylcysteine, at higher concentrations, has an inhibitory effect on matrix metalloproteinase-2 and matrix metalloproteinase-9 activity, regardless of the tissue origin and the differential effect on secretion depending on the tissue and N-acetylcysteine concentration. 相似文献

The purpose of this study was to investigate the relationship between a decrease in the peripheral fat content by suction-assisted
lipectomy (SAL) and serum leptin levels. Twenty-two healthy females who underwent SAL for aesthetic reasons participated in
the study. The data included height, weight, dietary habits, and leptin levels before surgery and at 1 and 6 weeks postoperatively.
The aspirate ranged between 1000 and 6000 ml, with an average of 2700 ml. Thirteen patients with an aspirate of over 2700
ml all experienced an immediate postoperative decrease in appetite which returned gradually by 12 to 17 days postoperatively.
They lost an average of 7% of the total body weight at 6 weeks. The leptin levels 1 week postoperatively were significantly
lower than the preoperative levels (p < 0.01); at 6 weeks the decrease in leptin level was not statistically significant. In conclusion, a reduction of the peripheral
fat content of more than 2700 ml by SAL has an immediate effect on leptin levels that lasts at least 1 week and correlates
with voluntary changes in energy intake. 相似文献

Tonsillitis is one of the most prevalent infections in children and adolescents. The etiologic agents might be viral or bacterial.
About 30% of cases are reported to be of bacterial origin, mainly due to group A Streptococcus (GAS). Although in most instances GAS tonsillitis is a self-limited disease, antibiotic treatment is recommended, mainly
to prevent the suppurative and nonsuppurative poststreptococcal sequelae of acute rheumatic fever and to prevent glomerulonephritis.
In this paper we review the current knowledge of the etiology of acute and recurrent GAS tonsillitis, with special emphasis
on a recent hypothesis regarding the etiology of bacterial eradication failure. While penicillin V remains the drug of choice
for acute tonsillitis, other antibiotics are being approved and recommended for particular indications in both Europe and
the United States. 相似文献

To define the frequency, natural history and clinical correlates of the murmur of mitral regurgitation (MR) detected after myocardial infarction, clinical data from 849 patients with documented acute myocardial infarction were analyzed. A murmur suggestive of MR was present on admission in 76 patients (9%). Patients with MR on admission were older and more apt to be female and nonwhite. They also had a significantly greater frequency of prior infarction and signs and symptoms of congestive heart failure. There was no difference in the location (anterior or inferior) of infarction. Patients with MR on admission had a 36% mortality compared to 16% for those who developed MR later in the hospitalization and 15% for those without MR by auscultation (p less than 0.001). Correction for differences in baseline variables indicated that the presence of MR on admission did not contribute independently to mortality. Thus, the murmur of MR derives its prognostic significance from integration of multiple clinical, radiographic and electrocardiographic characteristics. 相似文献

Renal angiomyolipoma with arteriovenous shunting 总被引:1,自引:0,他引:1

We describe a patient with arteriovenous shunting during renal arteriography who at operation was found to have an angiomyolipoma rather than renal cell carcinoma or an arteriovenous malformation. Renal angiomyolipoma should be added to the list of causes of gross hematuria with angiographically demonstrable arteriovenous shunting. 相似文献
