[Pancoast syndrome caused by lung tuberculosis].

Pancoast's syndrome arises from neoplasms in 95% of cases but infection is a rare cause. We describe a patient with Pancoast's tumor secondary to tuberculosis. Pain caused by plexopathy and lack of diagnosis by noninvasive means led to the need for open biopsy.

[Comparison of the place of origin of the referral of patients to hospital emergency service].

OBJECTIVES: To find the clinical and epidemiological differences in the place of origin (rural or urban) of patients attending a hospital Casualty Department (HCD) referred by a doctor. To detect problems in urgent non-hospital medical care, especially in rural areas. DESIGN: A descriptive crossover study. SETTING: "Centro" Health District, Sevilla. PARTICIPANTS: Patients referred to HCDs during 1995: Rural (R) = 3,521; Urban (U) = 13,203. MEASUREMENTS: The variables recorded for both groups were: age, sex, frequency of attendance, referral, diagnosis and destination of the patient. RESULTS: The urban population had a higher rate of attendance (131.8 visits per 1,000 inhabitants) than the rural (67.5). The percentage of referrals was greater from R (p < 0.001), although the proportion of population covered was similar. Age was similar, with more males from R. Abdominal and precordial pain and foreign bodies were the symptoms with most referrals from R; ear-ache, dizzy spells, minor surgery and fainting were from U. CONCLUSIONS: HCD is used to the same extent by R and U. More and better selected referred patients came from R. The rural doctor is the first to attend both serious and trivial pathology, whereas in the urban milieu the seriously ill patient goes straight to hospital.

[Analysis of mortality trends of ischemic heart disease in Andalucia (1975-1992)].

OBJECTIVE: To describe the evolution of mortality due to ischaemic heart diseases in Andalucia between 1975 and 1992 and predict rates up to the year 2000. DESIGN: Descriptive study. SETTING: The Autonomous Community of Andalucia. Patients and other participants. Deaths because of ischaemic heart diseases between 1975 and 1992 were obtained. MEASUREMENTS AND MAIN RESULTS: The direct method was used for the standardisation of mortality rates for age and sex, with the European population as the standard. Logarithmic transformations of the standardised rates for mortality due to ischaemic heart diseases for both sexes were performed and the regression lines were adjusted. Between 1975 and 1992 the theoretical rates went down both in men and women. If the same tendency were maintained, we would expect to see a moderate reduction between 1992 and 2000 in men and in women. CONCLUSIONS: The tendency of mortality due to ischaemic heart diseases in Andalucia is downwards in both men and women.

[Transmembrane Na+ transport kinetics in arterial hypertension: relations with vascular risk parameters].

BACKGROUND: To characterize the possible existence of kinetic anomalies of four erythrocyte membrane sodium transport systems in a group of essential hypertensive patients, and to study the clinical and biochemical profile of those with anomalies. METHODS: We studied 33 essential hypertensive patients and 33 normotensive controls. The kinetics (maximal rate and apparent dissociation constant for internal sodium) of Na(+)-K+ pump, Na(+)-K(+)-Cl- cotransport and Na(+)-Li+ countertransport was calculated after a sodium loading procedure, according to the methods of Garay; the passive Na+ permeability was also determined. RESULTS: The studied kinetic parameters were not significantly different in both groups. Nevertheless, we found a group of hypertensive patients with some transport abnormalities: increased intracellular sodium (9.1%), accelerated Na+ passive permeability (9.1%), lower activity of the Na(+)-K+ pump (7.1%) and the Na(+)-K(+)-Cl- cotransport (4%) and an increased maximal rate of the Na(+)-Li+ countertransport (11.8%). Na+Li+ countertransport activity was statistically related to plasma levels of urea, creatinine, glucose and LDL-cholesterol, and the activity of the Na(+)-K(+)-Cl- cotransport was related to plasma uric acid. The hypertensive patients with sodium transport anomalies showed higher body mass index, uric acid plasma levels and atherogenic index than those without these kind of anomalies, and they also showed lowered HDL-cholesterol plasma levels. CONCLUSIONS: A small group of essential hypertensive patients (around 31%) show kinetic alterations of sodium transport systems. There is a relation between Na(+)-Li+ countertransport activity and some cardiovascular risk parameters. Hypertensive patients with transport anomalies are a group with an increased cardiovascular risk.

[Mesenteric panniculitis: a case of acute and fatal presentation].

Mesenteric panniculitis is a rare process in which there is an inflammation of the mesenteric adipose tissue due to unknown causes and mechanisms. It evolves with abdominal pain and/or mass, among other symptoms, generally with a chronic and bening course. The concomitant tests are generally non-specific, the diagnosis being anatompathological. We present the case of an old woman who died hours after starting an episode of abdominal pain. The autopsy showed the presence of mesenteric panniculitis. The sudden onset of the clinical signs, without other justifying cause than the panniculitis itself, suggests that this must be considered in the differential diagnosis of acute abdominal pain. In addition, the absence of other morphological findings which could suggest a fatal cause make us to consider the relationship between this and the panniculitis.

[Communication between primary care and specialists].

OBJECTIVE: To assess how well referral and referral-back documents for rheumatology patients going back and forth between a health area's Primary Care and the specialist clinics are filled in. DESIGN: A descriptive retrospective study. Sevilla Central Health area. PATIENTS: These were the 233 patients with a referral document in their Clinical Notes, who were sent from Primary Care (both Health Centres (HC) and out-patient clinics (OC)) to the Rheumatology Service during 1991 (233 cases). MEASUREMENTS AND MAIN RESULTS: Out of the total, 69.96% (163) came from General Practitioners in out-patient clinics and 30.04% (70) from HC Family or General doctors. In HC the referral document was completed better than in OC, in the areas of clinical history, physical investigation and laboratory data. How well the referral-back document was filled in was independent of where the patient was referred from. 30.67% of the OC referrals and 15.71% of the HC ones were suggested by Area Specialists, without any significant differences existing. CONCLUSIONS: Patients coming from HC have their referral document better completed than those referred from out-patient clinics. The return document the HC patients take back is no better filled in by the rheumatologists. A high percentage of rheumatology referrals are suggested by Area Specialists but processed through Primary Care.
