[Adjusted morbidity groups: Characteristics and comorbidities in patients with chronic conditions according to their risk level in Primary Care]. / Grupos de morbilidad ajustados: características y comorbilidades de los pacientes crónicos según nivel de riesgo en Atención Primaria.

AIMS: To describe the characteristics of patients with chronic conditions according to their risk levels assigned by the adjusted morbidity groups (AMG). To analyse the factors associated with a high risk level and to study their effect. DESIGN: Observational cross-sectional study with an analytical focus. LOCATION: Primary care (PC), Madrid Health Service. PARTICIPANTS: Population of 18,107 patients stratified by their risk levels with the AMG in the computerised clinical records of Madrid PC. MAIN MEASUREMENTS: The variables studied were: socio-demographic, clinical-nursing care and use of services. Univariate, bivariate, and multivariate analysis were performed. RESULTS: Of the 18,107 patients, 9,866(54.4%) were identified as chronic patients, with 444 (4.5%) stratified as high risk, 1784 (18,1%) as medium risk, and 7,638 (77.4%) as low risk. The high risk patients, compared with medium and low risk, had an older mean age [77.8 (SD=12.9), 72.1 (SD=12.9), 50.6 (SD=19.4)], lower percentage of women (52.3%, 65%, 61.1%), a higher number of chronic diseases [6.7 (SD=2.4), 4.3 (SD=1.5), 1.9 (SD=1.1)], polymedication (79.1%, 43.3%, 6.2%), and contact with PC [33.9 (28), 21.4 (17.3), 7.9 (9.9)] (P<.01). In the multivariate analysis, the high risk level was independently related to age>65 [1.43 (1.03-1.99), male gender (OR=3.46, 95% CI=2.64-4.52), immobility (OR=6.33, 95% CI=4.40-9.11), number of chronic conditions (OR=2.60, 95% CI=2.41-2.81), and PC contact>7 times (OR=1.95, 95% CI=1.36-2.80)] (P<.01). CONCLUSIONS: More than half of the population is classified by the AMG as a chronic, and it is stratified into 3 risk levels that show differences in gender, age, functional impairment, need for care, morbidity, complexity, and use of Primary Care services. Age>65, male gender, immobility, number of chronic conditions, and contact with PC>7 times were the factors associated with high risk.

NP-59 test for preoperative localization of primary hyperaldosteronism.

PURPOSE: Adrenal venous sampling is generally considered the gold standard to identify unilateral hormone production in cases of primary hyperaldosteronism. The aim of this study is to evaluate whether the iodine-131-6-ß-iodomethyl-19-norcholesterol (NP-59) test may represent an alternative in selected cases. METHODS: Patients submitted to laparoscopic adrenalectomy for suspected primary hyperaldosteronism (n = 27) were retrospectively reviewed. When nuclear medicine tests were preoperatively performed, their results were compared with the histopathologic findings and clinical improvement. RESULTS: Nuclear medicine tests were realized in 13 patients. In 11 (84.6%), a planar anterior and posterior NP-59 scintigraphy was performed and a SPECT/TC in two (15.4%). Scintigraphy indicated a preoperative lateralization in 12 out of 13 patients (92.3%). When the value of NP-59 tests was based on pathologic results, it showed a sensitivity of 90.9% and a positive predictive value of 83.3%. When the nuclear medicine test's performance was based on postoperative blood pressure control, both sensitivity and positive predictive value were 91.6%. CONCLUSIONS: Nuclear medicine tests represent a useful tool in the preoperative localisation of primary hyperaldosteronism with a high sensitivity and positive predictive value. In patients with contraindications to adrenal venous sampling like contrast allergies, or when it is inconclusive, scintigraphy can represent a useful and non-invasive alternative.

Gender differential on characteristics and outcome of leprosy patients admitted to a long-term care rural hospital in South-Eastern Ethiopia.

INTRODUCTION: In previous studies, women are less aware of causation and symptoms of leprosy and have less access to health care coverage than men, thus contributing to their delay in seeking for treatment. We assess the gender differences in leprosy cases admitted to a rural referral hospital in Ethiopia for 7 and a half years. METHODS: Retrospective data of the leprosy patients admitted to referral hospital were collected using leprosy admission registry books from September 2002 to January 2010. Variables were entered in an Excel 97 database. RESULTS: During the period of study, 839 patients with leprosy were admitted; 541 (64.5%) were male, and 298 (35.6%) female. Fifteen per cent of female patients, and 7.3% of male patients were paucibacillary leprosy cases while 84.8% of female patients and 92.7% of males were multibacillary leprosy cases (p<0.001). Female leprosy patients were younger than male ones (median: 36 versus 44 years) (p<0.001). In the multivariate analysis, age (odds ratio [OR]: 0.97; 95% confidence interval [CI]: 0.96-0.98; p<0.001), admission for cardiovascular diseases (OR: 7.6, 95% CI: 1.9-29.3; p=0.004), admission for gastroenteritis (OR: 14.0; 95% CI: 1.7-117; p=0.02), admission from out patients clinic (OR: 2.04; 95% CI: 1.1-4.01; p=0.02), and mortality as final outcome (OR: 3.1, 95% CI: 1.2-8.0; p=0.02) were independently associated with female gender. CONCLUSIONS: Female patients with leprosy admitted to hospital were younger, had a different profile of admission and a higher mortality rate than male ones.
