The reference therapy for erysipelas is penicillin G given intravenously. Since I.V. injections are difficult to perform at home, hospitalization would seem mandatory. However, many cases of erysipelas are actually treated at home (cf. results of the 2 surveys concerning general practice). The lack of studies on non-hospitalized erysipelas patients makes it difficult to answer the following question: "What are the criteria for primary and secondary hospitalization?" The literature suggests, mostly indirectly, that the reasons of primary hospitalization are: the severity of general (fever, impairment of general condition, confusion) or local (blisters, purpura, skin necrosis, extent of the cellulitis, facial involvement) signs and symptoms, old age, associated diseases (diabetes, alcoholism, obesity, cardiovascular disease), the practical modalities of the treatment (penicillin given intravenously, bed rest), or the necessity to eliminate deep venous thrombosis. The reasons for secondary hospitalization are above all the (true or suspected) failure of oral antibiotherapy at home, or the occurrence of local complications. True criteria of primary or secondary hospitalization remain to be defined by adequate prospective studies performed in both in and outpatients. They will depend of the emerging possibilities of successfully treating erysipelas by oral antibiotics.

Although CHF has been considered a risk factor for venous thromboembolism, this has not been directly studied. We hypothesized that congestive heart failure would increase the risk of venous thromboembolism in an outpatient population, and that this risk would increase as patients' ventricular function worsened. We conducted a case-control study to examine whether CHF due to left ventricular dysfunction was an independent risk factor for acute venous thromboembolism in outpatients, once established risk factors such as recent surgery and prior venous thromboembolism are taken into account. We reviewed 106 cases of DVT and 603 controls, admitted for diabetes mellitus or infection, matched for month of admission at a VA hospital. Assignment of a diagnosis of venous thromboembolism required a definitive test, as did classification as CHF. In a logistic regression model CHF was an independent predictor of venous thromboembolism. A second logistic regression model showed that the risk of venous thromboembolism increased as the ejection fraction (EF) decreased, with an EF < 20 associated with a venous thromboembolism OR of 38.3 (95% CI 9.6, 152.5). CHF is an independent risk factor for venous thromboembolism, and the risk increases markedly as the EF decreases. These results support the use of anticoagulation in selected patients with CHF.

There are few long-term follow-up reports of the Angelchik prosthesis (AP). We report the longest follow-up series (66-192 months, average 145 months) to date. Between October 1983 and January 1994, 65 patients (45 men and 20 women) aged between 29 and 84 years (mean 52 years) had an AP inserted for gastro-oesophageal reflux (GOR) with or without hiatus hernia (HH). Clinical, radiological, endoscopy, and operative details were reviewed. Postoperative complications, investigations, and follow-up details were critically analyzed. All living patients (n = 53) with an AP in situ were interviewed and symptomatic assessment was carried out using a modified Visick system (I-IV). The average duration of the GOR symptoms before the operation was 5.7 years (range 10 months to 20 years). The average hospital stay was 8 days (range 5-15 days). Postoperatively, five patients developed chest infection/atelectasis, four had superficial wound infection, two had deep vein thrombosis (one with pulmonary embolism), one had urinary retention, and four developed an incisional hernia. Six patients (three with an AP in situ) died of other medical conditions. Ten (15%) patients had removal of the prosthesis. Eight (12%) and 11 (17%) had transient and persistent dysphagia, respectively. Thirteen (20%) and five (8%) patients had distal slippage and proximal migration of the prosthesis, respectively. One patient had erosion of the AP into the stomach, while in another patient, the straps of the prosthesis ruptured. Of the 53 living patients with an AP in situ, 28 (53%) were Visick I, 11 (20%) were Visick II, 11 (20%) were Visick III, and 3 (7%) were Visick IV. We conclude that the AP has poor long-term results, with only 66% attaining Visick I and II, and a prosthesis removal rate of 15% (10/65). Patients with preoperative dysphagia, hypothyroidism, and diabetes tend to do worse with an AP. Obese patients and those with failed previous fundoplication seemed to fare well with an AP. In view of poor long-term results and high incidence of complications as compared to other conventional operations for GOR, we cannot recommend the continued use of the AP.

The objective of this study was to assess the influence of oral contraceptives (OCs) on the risk of venous thromboembolism (VTE) in young women. A 5-year case-control study including all Danish hospitals was conducted. All women 15-44 years old, suffering a first ever deep venous thrombosis or a first pulmonary embolism (PE) during the period January 1, 1994, to December 30, 1998, were included. Controls were selected annually, 600 per year in 1994-1995 and 1200 per year 1996-1998. Response rates for cases and controls were 87.2% and 89.7%, respectively. After exclusion of nonvalid diagnoses, pregnant women, and women with previous thrombotic disease, 987 cases and 4054 controls were available for analysis. A multivariate, matched analysis was performed. Controls were matched to cases within 1-year age bands. Adjustment was made for confounding influence (if any) from the following variables: age, year, body mass index, length of OC use, family history of VTE, cerebral thrombosis or myocardial infarction, coagulopathies, diabetes, years of schooling, and previous birth. The risk of VTE among current users of OCs was primarily influenced by duration of use, with significantly decreasing odds ratios (OR) over time: <1 year, 7.0 (5.1-9.6); 1-5 years, 3.6 (2.7-4.8); and >5 years, 3.1 (2.5-3.8), all compared with nonusers of OCs. After adjustment for confounders, current use of OCs with second- (levonorgestrel or norgestimate) and third- (desogestrel or gestodene) generation progestins when compared with nonuse resulted in ORs for VTE of 2.9 (2.2-3.8) and 4.0 (3.2-4.9), respectively. After adjusting for progestin types and length of use, the risk decreased significantly with decreasing estrogen dose. With 30-40 microg as reference, 20 and 50 microg products implied ORs of 0.6 (0.4-0.9) and 1.6 (0.9-2.8), respectively (p(trend) = 0.02). After correction for duration of use and differences in estrogen dose, the third/second-generation risk ratio was 1.3 (1.0-1.8; p <0.05). In conclusion, use of OCs was associated significantly to the risk of VTE. The risk among current users was reduced by more than 50% during the first years of use. The risk increased more than 100% with increasing estrogen dose, and the difference in risk between users of third- and second-generation OCs, after correction for length of use and estrogen dose, was 33%.

Charcot joint is the painless, degenerative, progressive neuropathic destruction of the bony architecture of one or more joints of the feet. Diabetes mellitus is the most common cause of Charcot joint in North America, although the exact etiology is uncertain. The classic presenting complaint involves unilateral painless swelling of the lower extremity or foot. Charcot joint is often mistaken for cellulitis or deep vein thrombosis and may result in significant foot or ankle deformities. There are several treatment options for the patient presenting with Charcot joint. Medical management often includes immobilization and maintaining nonweightbearing status. Surgical intervention, often a final attempt at managing Charcot foot, involves careful patient selection and is not recommended for all patients. The postoperative phase can be challenging for both patient, nursing staff, and the surgeon.

Despite standardized tests (PT-INR) and better definition of therapeutic objectives, oral anticoagulation still leads to a significant number of hemorrhagic events. The risk is higher during the initial phase of treatment and for arterial indications, but must also be considered for other situations, including deep vein thrombosis, where the risk is less well defined. This risk can now be quantified on the basis of recent data used to identify at risk populations. The risk scores account for age, gender, associated cancer, weight, history of digestive tract bleeding or stroke, and comorbidity (recent myocardial infarction, hematocrit<30%, serum creatinine > 15 mg/l, diabetes). A high score is associated with higher risk of hemorrhagic events. Besides the patient's clinical status, the risk of hemorrhage is related to compliance, the level of anticoagulation, and drug interactions. Specialized monitoring centers provide a means of reducing the risk of morbidity and mortality. New anticoagulation agents must be developed to reduce the risk of hemorrhage which remains an important cause of morbidity and mortality, particularly in the elderly and patients at risk.

A carefully taken history and clinical examination are necessary for assessing the relative benefits and risks of estrogen replacement therapy for an individual patient. The patient's weight, blood pressure and urine need to be checked. Benefits of estrogen replacement are seen in relation to vasomotor symptoms, atrophy of the genital tract, bone metabolism, psychological symptoms, libido, skin, and cardiovascular effects. Estrogens are contraindicated with a history of previous deep vein thrombosis, ischemic heart disease or carcinoma of the breast. Care needs to be taken with liver disease, hyperlipidemias, diabetes, gallbladder disease, gross obesity, or in heavy smokers. Progesterones should always be administered if the uterus is present to prevent endometrial hyperplasia and adenocarcinoma. When properly selected and carefully monitored, many women may be relieved of unnecessary suffering due to menopause.

Barrier methods of contraception and natural family planning may pose unacceptable risks of unintended pregnancy for women with medical conditions in which pregnancy could be dangerous. Although more effective at preventing pregnancy, hormonal methods may affect the course of a chronic disease. The table that comprises this article outlines contraceptive choices and contraindications for women with the following diseases: breast cancer; endometrial, ovarian, and cervical cancer; deep venous thrombosis/pulmonary embolism; hypertension (past, moderate, or severe); diabetes (with and without vascular disease); liver disease; epilepsy; headache; and sickle cell disease.

An abrupt onset of a neurological deficit is a rare occurrence in patients with cystic fibrosis (CF). As many CF patients have indwelling intravenous catheters, one of the complications may be deep venous thrombosis. Cerebral thromboembolism through an intracardiac shunt should be considered in CF patients who develop unexplained acute neurological deficits. We report on the case of a 19-year-old CF patient with insulin-dependent diabetes mellitus who was on oral contraceptives and had a Port-A-Cath(R) in place. The patient developed an acute neurological deficit after pulmonary function testing. Radiologic investigations of her head and neck were unremarkable, except for bilateral maxillary and ethmoid sinusitis. An electroencephalogram showed epileptiform discharges primarily from the right hemisphere. A transthoracic echocardiogram (TTE) revealed a small thrombus in the right atrium. A transesophageal echocardiogram (TEE) demonstrated a left-to-right shunt through a patent foramen ovale (PFO) that was not found by TTE. Extensive investigation to rule out congenital and acquired thrombophilia was negative. Treatment consisted of aspirin and discontinuation of oral contraceptives and vitamin K supplementation. Spontaneous complete recovery of the neurological deficits occurred within 24 hr after onset of symptoms.We conclude that paradoxical embolism should be in the differential diagnoses of CF patients who have indwelling intravenous catheters and who develop an unexplained stroke. An extensive investigation to rule out intracardiac abnormalities and thrombophilia should be considered. The risks and benefits of PFO closure vs. prophylactic anticoagulant and antiplatelet aggregation treatment in this group of patients should be carefully weighed.

This article reviews several aspects of the association between obesity and cancer. Current perspectives of cancers of the breast, endometrium, colon and prostate are described. Obesity is a growing problem in contemporary societies, due to the rapid adoption of a modernized lifestyle that results in increased carbohydrate and fat-rich dietary intake, reduced physical activity and extended life expectancy. More than half of adult Americans are overweight or obese, and so is the population of many other countries. There are several definitions for the state of obesity. The body mass index (BMI), which measures overall adiposity, is universally available, the easiest to determine, and therefore the most commonly studied. Anthropometric measurements of subcutaneous fat distribution, such as measurement of girth, circumference of the arms, hips and thighs, or of skinfolds in various body regions are also often used. They allow to categorize the distribution of subcutaneous fat into android and gynoid types (den Tonkelaar, Seidell et al., 1994; Huang, Willett et al., 1999). The android, or abdominal, fat is determined from the waist to hip ratio, and is of particular relevance to cancer. Increased body weight and fat are associated with high health risks, and therefore body fat distribution and BMI are major predictors of obesity associated risks (Calle, Thun et al., 1999; "Overweight, obesity, and health risk," Yanovski, 2000). These include diabetes mellitus type 2, coronary heart disease, sleep apnea and pulmonary dysfunction, stroke, diseases of the gallbladder, liver and the musculoskeleton, reproductive dysfunction, venous insufficiency, deep vein thrombosis, poor wound healing, and more (Pi Sunyer, 1993; "Overweight, obesity, and health risk", Yanovski, 2000). All these are associated with increased mortality, especially in individuals with other risk factors (Calle, Thun et al., 1999). Cancer is also associated with obesity (Garfinkel, 1985), and the present paper attempts to summarize current perspectives of this association, especially in cancers of the breast, endometrium, colon and prostate.
