ABSTRACT
BACKGROUND: To determine the prevalence of abdominal aortic aneurysm (AAA) (arterial diameter ≥30mm), in patients with high or very high cardiovascular risk (CVR) and to evaluate their clinical features. PATIENTS AND METHODS: Observational, cross-sectional and multicentric study conducted in Spanish Internal Medicine Services. We enrolled men with age >55years and women >65years who had a high or very high CVR. RESULTS: The study included 659 patients. The prevalence of AAA was 8% (53 patients). 76.9% were male with a mean age of 71±8.7years. The multivariate analysis showed an association between AAA and age (OR: 1.06; 95%CI: 1.02-1.1; P<.01), male sex (OR: 5.6; 95%CI: 1.6-18.8; P=.01), active smoking (OR: 3.22; 95%CI: 1.16-8.93; P=.024) and peripheral arterial disease (OR: 3.51; 95%CI: 1.73-7.09; P<.01). Diabetes mellitus was an independent protective factor (OR: 0.41; 95%CI: 0.22-0.78; P=.06). Those with subaneurysmal dilatation of the abdominal aorta (diameter 25-29.9mm) presented similar features as patients with AAA. CONCLUSIONS: The prevalence of AAA in patients with high CVR is high. Ultrasound screening can be performed by general practitioners. Men >65years with elevated CVR could benefit, particularly in the presence of active smoking or peripheral arterial disease.
ABSTRACT
A parapneumonic effusion should be drained if it is large (≥ 1/2 of the hemithorax), loculated, frank pus is obtained, if the fluid is non-purulent fluid but has a low pH (< 7.20) or if the culture is positive. Instillation of fibrinolytics and DNase thorough the chest catheter in locutated effusions and empyemas is currently recommended. Management of spontaneous pneumothorax is fundamentally influenced by the patient's symptoms. Insertion of a chest catheter is mandatory if there is significant dyspnea, hemodynamic instability or large pneumothoraces (≥ 2 cm). Pleural ultrasonography confirms the presence of air or fluid in the pleural space and serves to guide any pleural procedure (e.g., thoracentesis, chest tubes). The use of small-bore 12F catheters inserted via the percutaneous Seldinger technique under ultrasonography guidance is a safe and effective procedure in complicated parapneumonic effusions/empyema and most pneumothoraces.

OBJECTIVE: To measure the differences of waiting time for the emergency admission depending on which professional is in charge ie. the emergency doctor or the specialist of a specific area. PATIENTS AND METHODS: Once the Hospital Emergency Service was permitted to admit patients directly to the specialities, two periods of study where taken: Period A (before the direct admission) and Period B (after the implementation of it). The following was analysed: the number of patients taken, the complexity of their problem, the number of admissions and length of their stay. RESULTS: During Period A 41,917 patients were seen (228.07 patients/day) and during Period B 41,948 (230.48 patients/day). The average of the stay for those patients that were admitted directly from Emergencies had decreased by 1h and 42 min (p=0.001). The admissions in the Internal Medicine Service kept the same waiting time in both periods. CONCLUSIONS: The transfer of the responsibility of the admissions to emergency doctors has decreased the average waiting time of the patients in this area. The total number of admissions has not increased and has reduced the amount of work the different specialist.

The collection and consumption of wild mushrooms by individuals with no mycological knowledge and their accidental ingestion by minors are responsible for a growing increase of poisonings. It is not usual for emergency care of a patient affected by mushroom poisoning to be based on recognition of the responsible species of fungus or access to a sample of the mushroom consumed. It is this reason knowledge of toxidromes is crucial. In the majority of cases, the symptoms are weak. Mortality is usually related to the development of potentially fatal liver necrosis after consumption of the fungus Amanita phalloides and others which contain amatoxins. Treatment is based on support measures but no specific treatments exist that are based on scientifically proven studies. In the following article the clues used in diagnosing which make it possible to carry out a syndromic diagnosis based on a period of latency will be analyzed. The mushrooms that are responsible for the most common syndromes, therapeutic options, as well as varieties of toxic fungus which may produce peculiar and exceptional symptoms are also reported.

We report the clinical-radiological case of a 25 year-old female patient who developed reversible posterior leukoencephalopathy syndrome (RPLS) in the postpartum period, without evidence of preeclampsia-eclampsia or chronic arterial hypertension. RPLS is associated with diverse clinical entities including eclampsia. Ten days after giving birth, the patient presented with clinical symptoms of headache, elevated blood pressure and seizures. Reversible vasogenic oedema affecting the white matter in the posterior regions was the characteristic finding in magnetic resonance imaging (MRI) of the brain. Although the prognosis is favourable, treatment needs to be early and aggressive, with rapid control of the convulsions and arterial hypertension, with the aim of preventing ischemia and cerebral infarct from developing. There is a need to be highly alert and to consider the diagnosis of RPLS in women presenting with convulsions and other neurological symptoms in postpartum.

OBJECTIVE: To evaluate the T helper 1 (T(H)1)/T helper 2 (T(H)2) lymphocyte cytokine profiles in women and men and to study the in vitro effects of sex hormones on lymphocyte secretion of cytokines. METHODS: Analysis of serum concentration and lymphocyte synthesis of T(H)1 (gamma interferon (INF-gamma) and interleukin 2 (IL-2)) and T(H)2 (interleukin 4 (IL-4) and interleukin 10 (IL-10)) cytokines was performed in 20 women and 15 men. Analysis of modifications in cytokine secretion induced by supplementation of lymphocyte culture with increasing concentrations of sex hormones was carried out. RESULTS: Higher levels of INF-gamma and IL-2 and lower levels of IL-4 and IL-10 were detected in the phytohemagglutinin-stimulated lymphocyte culture supernatants of men compared with women; the INF-gamma:IL-4 ratio was significantly higher in men. In women, similar concentrations of all the cytokines were detected in culture supernatants obtained during the follicular and the luteal phases. The addition of sex hormones did not modify the concentration of cytokines in supernatants of phytohemagglutinin-stimulated T-cell cultures. CONCLUSIONS: Women present a predominant T(H)2 cytokine profile, which could be involved in immune responses characterized principally by the secretion of antibodies. This could be a factor implicated in the higher concentration of immunoglobulins or the increased prevalence of autoimmune diseases detected in females.

BACKGROUND: The aim of the present was to study the clinical characteristics and prognostic factors of 20 cases of pneumonia by Pneumocystis carinii (NPC) diagnosed over the last 10 years in renal, renopancreatic, liver and bone marrow transplant recipients. METHODS: The clinical histories of all the patients transplanted in the authors' hospital from 1985 to 1994 who developed NPC were analyzed. Diagnosis was established by visualization of cysts in methenamine silver staining of bronchialveolar lavage (BAL) samples. RESULTS: The global incidence of NPC in our transplant population was 1%. However, the incidence was 3% in the recipients who did not receive prophylaxis. No patient in this series received prophylaxis at the time of diagnosis. Ninety percent of the patients had history or rejection. Pneumonia was observed in 15 (75%) in the first 6 months post transplantation. The mean length of the symptoms prior to diagnosis was 10 days. Ninety-five percent of the patients presented cough, dysnea and fever. Radiology demonstrated diffuse alveolointerstitial infiltrates in 18 patients (90%). Basal arterial PO2 was lower than 60 mmHg in 14 (70%) patients and the alveoloarterial gradient of oxygen was greater than 60 mmHg in 9 (45%). Mechanical ventilation was required in 50% of the patients. BAL demonstrated cytologic alterations compatible with CMV infection in 50% of the cases and in two Aspergillus fumigatus was associated. Mortality was 35%. The only variable significantly associated with bad prognosis was the need for mechanical ventilation (p = 0.003). CONCLUSIONS: The incidence of pneumonia by P. carinii in a population of transplant recipients was 1%. No patient received primary prophylaxis at the time of diagnosis. Most of the episodes were observed during the first 6 months post transplant. Mortality was 35% with the only variable with prognostic significance being the need for mechanical ventilation.
