Deep vein thrombosis is a serious complication of oral contraception. The most serious complication, pulmonary embolism, could be lethal. The relative risk of thromboembolic disease is four time higher in women using oral contraception. Both the amount of estrogen and the type of gestagen can increase the relative risk of thromboembolic disease. Oral contraceptives influence procoagulants, fibrinolytic system and inhibitors of coagulation. The choice of oral contraceptive should be very careful. It is advised to use preparations with less then 50 micrograms of ethinyl-estradiol and the type of gestagen that has minimal metabolic side effects, including minimal effect on coagulation. It is not recommended to perform screening of trombophilia before prescribing oral contraception. Family history of thrombosis is indication for more detailed investigation. However in the case of positive history of thromboembolic disease use of oral contraception is contraindicated. Oral contraception users should be informed about increased risk of deep vein trombosis, and what to do to prevent deep vein thrombosis. 相似文献

Thoracic outlet syndrome (TOS) is caused by compression of peripheral nerves and vascular structures along their course through
the upper thoracic aperture to the axilla. The aim of our study was to analyze long-term outcomes of different treatments
stratified by symptom severity. We performed a retrospective analysis of a cohort of 73 consecutive patients treated at our
institution presenting with TOS-associated venous thrombotic events. Treatment strategies and immediate outcome analysis were
completed by long-term follow-up with duplex ultrasound controls 6–12 months after the initial clinical event. Conservative
therapy was started in mildly symptomatic patients (n = 32), of which 12 required endovascular procedures because of treatment failure. Endovascular treatment was attempted in
all highly symptomatic patients and in those with conservative treatment failure (n = 53), of which 12 required acute surgical intervention. Elective surgical treatment was indicated in 30 other patients because
of persistent symptoms. Surgery was associated with a significantly lower rate of the ultrasound-detected signs of persisting
vascular compression. However, the rate of persisting clinical symptoms was comparable to those treated only by endovascular
or conservative therapy. Our data demonstrate that initial endovascular treatment proposed as first line therapy to highly
symptomatic subjects and in those with conservative treatment failure improves the symptoms in 77% of patients avoiding the
need of acute surgery. Acute and elective surgical decompression leads to lower rates of vascular compression signs without
significant amelioration of persisting clinical symptoms as compared to endovascular or conservative therapy. 相似文献

Bilateral leg compartment syndrome due to myonecrosis caused by inappropriate use of statins is a rare but potentially fatal complication of this lipid lowering medication. We report a case of a 39-year-old woman who presented with suspicious critical lower limb ischemia. Subsequently, bilateral leg compartment syndrome and myonecrosis developed. The primary cause of myonecrosis was due to misuse of simvastatin mistaken by the patient for a weight-reducing drug. Urgent fasciotomies were performed and the patient underwent urgent renal replacement therapy with continuous hemodialysis for acute renal failure due to myoglobinuria. After this complex treatment, the patient was discharged. She almost fully recovered with only a residual paresis of the left fibular nerve. According to literature, this is a unique case of bilateral compartment syndrome and myonecrosis with acute renal failure due to statin overdose leading to acute renal failure and bilateral fasciotomy. 相似文献

AIM: The injection of bone marrow mononuclear cells (BMMC) into the gastrocnemius muscle has given promising results in patients with critical limb ischemia (CLI). In this article, we have assessed whether a less invasive procedure, i.e. intravascular BMMC infusion, could be effective in this population of patients. METHODS: A total of 28 limbs in 24 patients with CLI were treated. An amount of 276-700 mL of marrow blood was harvested from posterior iliac crests and BMMC were obtained by standard procedure used for bone marrow transplantation. After performance of digital subtraction angiography, BMMC were injected laterally through a 4 Fr sheet. Primary outcome was efficacy of the procedure measured as healing of defects, frequency of high amputations and change of ischemia grade; among secondary outcomes were safety of the procedure, angiographic changes and changes in quality of life. RESULTS: One year after treatment, all patients were alive and only 2 patients have undergone high amputation. Eleven of 14 defects have healed (78%) and Fontaine grade of ischemia has changed from median grade 3.5 to median grade 2 (P<0.0001). Collateral vessel development has improved by mean 1.13 and 1.3 points on a four-point semiquantitative scale in calf and foot, respectively (P<0.0001). There were no grade III-IV adverse events. According to the SF-36 quality of life questionnaire, 1 year after the procedure patients have reported significant improvement in all measured items. CONCLUSION: Intra-arterial infusion of BMMC can lead to significant and long-lasting subjective and objective improvements in patients with CLI. The results merit validation by randomized controlled studies in patients with less critical limb ischemia. 相似文献

Informational value of the prevalence of antiborrelia antibodies in a healthy and at risk population
Bartůnĕk P Mrázek V Varejka P Sklenár T Bína R Listvanová S Janovská D 《Epidemiologie, mikrobiologie, imunologie : casopis Spolecnosti pro epidemiologii a mikrobiologii Ceské lékarské spolecnosti J.E. Purkyne》2000,49(1):4-10
The authors tried to confirm data on the prevalence of antiborrelia antibodies class IgM and IgG in the local healthy population (200 blood donors) and in subjects with an increased risk of infection (forestry labourers, forestry workers and huntsmen). All blood samples were analyzed in the National Reference Laboratory for Lyme borreliosis CEM (LB) in the National Institute of Public Health in Prague by the ELISA NRLB KC 90 method and in case of a positive result they were confirmed by the Western blot Lyme method. All patients completed a special questionnaire used as a standard procedure in the consultation centre for LB. In the group of blood donors 100 men were examined, mean age 33.5 years and 100 women, mean age 24.4 years. In 26 positive antibodies against Borrelia burgdorferi (Bb) were confirmed, but on invitation to medical examination only 22 attended, 11 men and 11 women (10.1%). Examination of antiborrelia antibodies by the ELISA method proved positivity of class IgM 7 times and of class IgG 9 times. By the Western blot method (WB) class IgG was confirmed three times. In the risk group 39 men were examined, mean age 40.6 years and 32 women. In 12 of them (17.9%) positivity of antiborrelia antibodies against Borrelia burgdorferi (Bb) was proved by the ELISA method as well as the WB method. If the percentage confidence interval of the control group is taken as a basis for comparison, then the value of the risk group is within this interval at a significance value of alpha = 0.01. In the conclusion the authors discuss the problem of interpretation of positive serological results and the pitfalls of their evaluation not only from the aspect of validity of laboratory findings, due to the absence of standardization of methods, but also with regards to obscure aspects of the persistence of IgM antibodies after years of lege artis antibiotic treatment. 相似文献

According the literature atrio-ventricular blockade (AVB) is the most frequent and well-known symptom of Lyme carditis. Typical signs of complete AVB include fatigue, lethargy and syncope- Morgagni-Adams-Stokes syndrome (MAS). The authors present their results and experience with 5 patients selected from a long-term study (conducted between 1987 and 1998) comprising 58 patients who developed MAS. The authors tried to evaluate the changes especially in the cardiovascular system. They correlated the clinical state with ECG findings, as well as with the levels of the Borrelia burgdorferi antibodies. The following results were obtained: 1) all patients had typical syncope, 2) the clinical course was not complicated (except one patient who developed ventricular fibrillation), 3) two patients had frequent symptomatic and asymptomatic arrhythmia including chest pain and episodic rest dyspnea, 4) subjective difficulties (usually palpitations) correlated with ECG findings (Lown 3a, 3b). The authors also looked for any relationship between clinical difficulties and levels of antibodies. The results obtained with an early permanent pacemaker were less favourable than those reported in the literature. Despite early treatment 2 patients had repeated palpitations and ECG correlates during the next years. 相似文献

Camel contagious ecthyma (pustular dermatitis) 总被引:1,自引:0,他引:1
In 1979, pustular dermatitis caused by a virus belonging to the family Poxviridae , genus Parapoxvirus , was observed among camels in some areas of Mongolia . The morbidity in adults ranged from 10 to 80%, of 2 to 3-month-old suckling camels between 50-70% and it reached 100% in 1-year-old animals. In the beginning, pustules developed around the mouth followed by papular elevations and scab formation. The virus designated camel contagious ecthyma (CCE) grew on the chorionallantoic membrane (CAM) of 11-day-old chick embryos (CE). The disease was transferred to the scarified skin of 2 to 3-month-old camels. Vaccination with the material containing CCE virus seemed to be promising. In contrast, camels were not protected after immunization with vaccinia virus and with a vaccine against sheep and goat contagious ecthyma. 相似文献
