[Pneumonia above 80 years, admitted to the hospital]. / Neumonía en el anciano mayor de 80 años con ingreso hospitalario.

OBJECTIVE: To analyze and compare differences in patients older than 80 years with Community acquired Pneumonia admitted in Internal Medicine or Pneumology of a General Hospital from the Emergency Room. MATERIAL AND METHODS: Retrospective study of all the 277 patients above 80 years admitted into the Hospital in 2005 with the main diagnosis of Pneumonia. RESULTS: 84% community-acquired, 16% from Institutions. Mean age: 85.8 y (48% men, 52% women). 19% FINE-3, 49% FINE-4, 32% FINE-5. Known etiology: 25% (Pneumococcal 19%, H. Influenzae and other Gram (-) 6%. 75% treated by Internists, 22% treated by Pneumologists. Standard Guidelines followed up by 30,5% a variant 60% (Equal by Internists or Pneumologists). Time door-1st antibiotic dose 6.6 hours. Global Mortality 16.7%. Women died at 87.4 y, men at 84.5 y (p = 0.035). Mortality FINE 3-4-5: 4.5, 12.4, 30% respectively. Mortality treated before 4 hours: 34.6%, after 4 hours: 11.5% (p = 0.01). Many more FINE 5 cases in Int. Medicine than Pneumology. Mortality by Internists 22%. Mortality by Pneumologists 3% (p = 0.001). Mortality similar following strict guidelines or variant. CONCLUSIONS: a) Internist receive patients sicker than Pneumologists; b) Important mortality in these very old patients of 16.7%, and progressive according the FINE severity index, in spite of correct therapy; c) Rapid initiation of Antibiotics did not decreased mortality; d) Mortality did not change following strict or variant Guidelines; and e) There are areas of quality improvement in our Hospitals.

[The principal causes of mortality in young people in the Autonomous Community of Madrid: 1990-1991]. / Principales causas de mortalidad en jóvenes en la Comunidad Autónoma de Madrid: 1990-1991.

Our objective is to quantify the mortality from AIDS, narcotic related deaths, and traffic accidents among those between 15 and 39 years of age, in the Community of Madrid, 1990-1991. Data provided by the Regional Register of AIDS, Forensic Institute of Madrid, local police teams and the Traffic Directorate General have been used. Mortality from traffic accidents ranked first as a cause of death, followed by narcotic-related deaths and AIDS, both for men and women.

[Intravenous drug addiction and the risk of HIV infection in Madrid in 1990]. / Drogadicción intravenosa y riesgo de infección por VIH en Madrid 1990.

As part of a multicenter WHO study on HIV infection among drug injectors, 472 intravenous drug users (IDUs) were interviewed, 240 recruited in the streets and 232 at drug treatment centers. The objectives of the study were to assess the prevalence of HIV infection among IDUs of Madrid, to identify factors associated with risk reduction behaviors, such as the use of sterile syringes and condoms. Chi-square and logistic regression were used to test for differences and to estimate odds ratios. Prevalence of HIV infection among IDUs in Madrid was 50% (53% among those recruited in the street and 38% among those recruited at treatment centers). Forty five per cent of those interviewed were still sharing syringes. Out of the 315 sexually active subjects, only 22% reported using condoms always or almost always. These results suggest that a range of interventions should be implemented to promote change towards healthier behaviors, including syringe-exchange programs, methadone maintenance treatments and pre- and post-test counseling in those agencies which care for this population.

[Urinary tract duplication]. / Duplicaciones del tracto urinario.

OBJECTIVES: Review the clinical and radiological characteristics of the different kinds of urinary tract duplications, assessing the outcome of the cases and the incidence of renal parenchymal injury. MATERIAL AND METHODS: A retrospective study was performed including 301 children diagnosed of renal duplication by urological ultrasound, voiding cystourethrogram (VCUG) and 99-technetium renal scintigraphy (DMSA). RESULTS: They were classified in four groups. The first consisted of 166 (55.1%) cases that had complete ureteral duplication without an obstructive component (CD). The cases that had an upper system obstruction due to an ectopic ureter (EU), 19 (6.3%), or an ureterocele (UTC), 35 (11.6%), were divided into two different groups. The fourth group 81 (26.9%) had incomplete ureteral duplication. The nephro-urological study was performed in 181/301 after a urinary tract infection; in 100/301 after a prenatal finding of hydronephrosis. It was a casual diagnosis in 20/301. The percentage upper kidney dilation in the diagnostic ultrasound was significantly higher in those with EU 16/19 (84%) and in those with UTC 33/35 (94%), compared with the upper pole dilations found in the CD 35/166 (21%) and ID 21/81 (25%). Surgery was performed in 96/166 (41%) of the CD, 7/81 of the ID, 16/19 (84%) of the EU, and 34/35 (97%) of the UTC. Three cases with EU and 8 with UTC needed a second surgery, and 3 a third one. No scintigraphy changes were observed in 58% of the patients in the CD group, 87% in the ID group, 29% in the EU group, and 5% in the UTC group. As regards the renal duplications who did not have surgery, it was found that there were 98 refluxing units in the CD, and 74 in the ID. The spontaneous resolution of the vesicoureteral reflux (VUR) was 80% in the CD, and 90% in the ID (McNemar test P<.001). The average healing time ranged from 1 year to 5 years (Mean: 3 years and 3 months). CONCLUSION: The patients with higher risk of having renal injury are those who presented with a duplication with upper kidney obstruction due to ectopic insertion of the ureter, particularly due to an ureterocele.

Hiponatremia e hipofosforemia en las neumonías: ¿qué papel desempeña el riñón? / Hyponatremia and hypophosphatemia in pneumonia: what role does the kidney?

Antecedentes: La hiponatremia es una alteración electrolítica relativamente frecuente en pacientes con neumonía, cuya patogenia se relaciona con el síndrome de secreción inapropiada de hormona antidiurética. El objetivo de este estudio era describir las alteraciones hidroelectrolíticas y hormonales en niños, previamente sanos, diagnosticados de neumonía adquirida en la comunidad (NAC), y compararlas con las de los niños sanos. Material y métodos: Se llevó a cabo un estudio de casos y controles. El grupo de casos (n= 25) estuvo formado por pacientes diagnosticados de NAC según criterios de la Organización Mundial de la Salud, con una media de edad de 4,2 ± 2,4 años; ninguno había recibido fluidoterapia intravenosa. En el grupo control (n= 27) se incluyeron niños sanos, con una media de edad de 5 ± 2,6 años, autorizados a participar en el estudio. Se realizó un análisis bioquímico en sangre y en orina (en micción aislada). En el grupo de NAC se determinaron las cifras de proteína C reactiva (PCR), procalcitonina (PCT) y vasopresina (ADH). Resultados: Los valores medios séricos del sodio, aunque en rango normal, fueron significativamente menores en el grupo de casos que en el grupo control, al igual que la excreción fraccional de sodio (EFNa), cuyo valor medio fue significativamente menor que el del grupo control. No hubo relación entre la natremia, la EFNa y los niveles de ADH. Se encontró una relación significativamente negativa entre los valores de sodio y la temperatura axilar (r= -0,64; p <0,001), la PCR (r= -0,41; p <0,04) y el recuento de leucocitos (r= -0,43; p <0,01) en sangre periférica. El valor medio del fósforo sérico era significativamente inferior al del grupo control. Se encontró una relación significativa entre la fosforemia y la reabsorción tubular de fosfato, expresada mediante TP/GFR (r= 0,97; p <0,001), y la PCR (r= -0,4; p <0,04). Conclusiones: En esta serie, los pacientes con NAC muestran una clara tendencia a presentar un descenso de la natremia. Esta tendencia es de causa extrarrenal y se relaciona significativamente con el proceso inflamatorio secundario a la infección. El descenso del fósforo sanguíneo también se relaciona con la infección, y es secundaria a una pérdida excesiva de fósforo por el riñón (AU)

Introduction: Hyponatremia is a relatively common electrolyte disturbance in patients with pneumonia and its pathogenesis has been related with the syndrome of inappropriate secretion of antidiuretic hormone. The aim of this study was to describe the electrolyte and hormonal abnormalities in children diagnosed with community-acquired pneumonia (CAP) and compare them with those obtained in healthy children. Material and methods: This is a case-control study. In the case group we included patients with CAP (n= 25), according to WHO criteria. None of the patients has received intravenous fluids. The control group (n= 27) included healthy children without disease. Biochemical blood and urine (isolated urination) were determined as analytical tests. In the CAP group C-reactive protein (CRP), procalcitonin (PCT) and levels of vasopressin (ADH) were determined. Results: The serum sodium mean values and the fractional excretion of sodium (FENa) were significantly lower in the case group than in the control group, although they were both in the normal range. There was no relationship between serum sodium, FENa and ADH levels. A significantly negative relationship was found between sodium and axillary temperature (r= -0.64; p <0.001), CRP (r= -0.41; p <0.04) and the leukocyte count in peripheral blood (r= -0.43; p <0.01). The mean serum phosphorus level was significantly lower in the case group. A remarkable relationship between phosphoremia and tubular phosphate reabsorption, expressed by TP/GFR (r= 0.97; p <0.001), and CRP (r= -0.4; p <0.04) was found. Conclusions: In this series, cases with CAP show a clear tendency of decreased serum sodium. This trend has an extrarenal cause and it is significantly related to the inflammatory process secondary to the infection. Hypophosphoremia also relates to infection and is secondary to excessive loss of phosphorus by the kidney (AU)

[Attitudes of primary care health staff to the mentally ill patient, psychiatry and the mental health team]. / Actitudes del personal sanitario de atención primaria hacia el enfermo mental, la psiquiatría y el equipo de salud mental.

OBJECTIVES: To measure the reliability of a questionnaire on attitudes and knowledge of mental health and the mental health team (MHT). To find out what these attitudes are and their associations with demographic and work variables. DESIGN: Observational, transversal. SETTING: Primary care (PC) centres in an urban environment. PARTICIPANTS: Health staff (n=141) of PC centres whose mental health centres (MHC) for referral are in an area of Guipuzcoa. MAIN MEASUREMENTS: Self-administered, anonymous questionnaire including a section with social, demographic and work data. Survey including items on attitudes towards the mentally ill, psychiatry, the MHCs, staff's perception of their own knowledge and their attitude towards attending courses on the subject. RESULTS: The reply rate was 70%. The factorial analysis had 5 factors whose measurements and scores were: "attendance at courses", 30.8 (8-40); "knowledge", 17.5 (7-35); "more treatment", 12.2 (6-30); "less treatment", 14.4 (5-25); "care through the MHC", 11.5 (4-20). The internal consistency of the 5 scales was 0.95, 0.92, 0.85, 0.83, and 0.65, respectively. 13% did not think you had to be on the look out for the mentally ill. CONCLUSIONS: No negative attitude towards the mentally ill was perceived. PC health staff perceived their lack of psychiatric knowledge and that they did not have sufficient dealings with the MHC, and showed good predisposition towards improving both questions.

Duplicaciones del tracto urinario / Urinary tract duplication

Objetivos: Revisar las características clínicas y radiológicas de las distintas formas de duplicación del tracto urinario, valorando la evolución de los casos y la incidencia de lesión en el parénquima renal. Material y métodos: Se estudió retrospectivamente a 301 niños diagnosticados de duplicación pieloureteral mediante ecografía urológica, cistografía miccional seriada (CUMS) y gammagrafía renal con tecnecio99 (DMSA). Resultados: Se clasificaron en 4 grupos. El primer grupo estaba constituido por 166 (55,1%) casos, que presentaban una duplicación pieloureteral completa sin componente obstructivo (DC). Los que presentaban una obstrucción del sistema superior, bien por presentar un uréter ectópico (UE) 19 (6,3%) o un ureterocele (UTC) 35 (11,6%) se dividieron en 2 grupos distintos. El cuarto grupo 81 (26,9%) presentaban una duplicación pieloureteral incompleta (DI). El estudio nefrourológico se realizó en 181/301 tras presentar una infección del tracto urinario; en 100/301 tras detectarse prenatalmente una hidronefrosis. En 20/301 el diagnóstico fue casual. El porcentaje de ecografías al diagnóstico con dilatación del hemirriñón superior fue significativamente superior en los UE 16/19 (84%) y en los UTC 33/35 (94%), en relación con las dilataciones del polo superior encontradas en DC 35/166 (21%) y DI 21/81 (25%).Fueron intervenidos quirúrgicamente 69/166 (41%) de las DC; 7/81 (9%) de las DI; 16/19 (84%) de los UE, y 34/35 (97%) de los UTC. Tres casos con UE y 8 con UTC requirieron una segunda intervención y 3 fueron sometidos a una tercera intervención. El 58% de los pacientes pertenecientes al grupo de DC, 87% de las DI, 29% de los UE, 5% de los UTC, no mostraron alteraciones gammagráficas. Al estudiar las duplicaciones renales no intervenidas se observa que había 98 unidades refluyentes en las DC y de 74 en las DI. La tasa de resolución espontánea de los RVU fue del 80% en la DC y del 90% en la DI (prueba de McNemar p<0,001). El tiempo medio de curación osciló entre 1 año y 5 años (media de 3 años y 3 meses). Conclusión: Los pacientes con más riesgo de presentar lesión renal son los que presentaban una duplicación con obstrucción del hemirriñón superior por inserción ectópica del uréter y especialmente por ureterocele (AU)
