Niveles séricos de la isoenzima creatina quinasa-MB y lactato deshidrogenasa como indicadores de daño miocárdico en perros con enfermedad valvular degenerativa

Se analizaron los niveles séricos de creatina quinasa-MB (CK-MB) y lactato deshidrogenasa (LDH) en 10 perros diagnosticados con enfermedad valvular degenerativa y en seis perros clínicamente sanos, con el objetivo de evaluar si sus niveles séricos indican daño miocárdico. Las muestras de suero se analizaron mediante el método UV. Se utilizó la prueba de diferenciación de medias para determinar diferencias entre medias, y la prueba de correlación de Pearson para determinar si existe correlación entre los niveles séricos de ambas enzimas. Los valores de CK-MB y de LDH fueron significativamente diferentes entre los dos grupos de pacientes. Los niveles de CK-MB y LDH tuvieron correlación positiva, pero no significativa.

Primary care consultation liaison and the rate of psychiatric hospitalizations: a countrywide study in Chile

Objectives

To assess the quality of consultation liaison across all primary health care centers in Chile, and its potential relationship with the psychiatric hospitalization rate.

Methods

We carried out a countrywide ecological cross-sectional study on 502 primary health centers in 275 municipalities (87.3% of total primary health centers in Chile) during 2009. We characterized the presence of consultation liaison using four criteria: availability, frequency, continuity of participants, and continuity across care levels. We also created a dichotomous variable called “optimal consultation liaison” for when all four criteria were met. A quasi-Poisson regression model was used to estimate the rate of hospitalization due to different psychiatric disorders, adjusting by population attributes.

Results

Of the primary health centers, 28.3% of them had had optimal consultation liaison during the preceding year, concentrated in the poorest and richest municipalities. Continuity of care was the criterion that was met least often (38.3%). The presence of optimal consultation liaison at the municipal level was associated with fewer psychiatric discharges, with the following incidence rate ratios and 95% confidence intervals (CIs): schizophrenia, 0.65 (95% CI: 0.49–0.85); other psychoses, 0.68 (95% CI: 0.52–0.89); and personality disorders, 0.66 (95% CI: 0. 49–0.89). Municipalities with optimal consultation liaison showed 2.44 fewer total psychiatric discharges per 10 000 inhabitants, although without reaching statistical significance (-0.85 to 5.70).

Conclusions

Using a nationally representative sample, we found that consultation liaison in primary care was associated with having fewer psychiatric hospitalizations. More studies are required to understand the role of each component of consultation liaison.

[Analysis of Governance in the Implementation of the Chilean Community Mental Health ModelAnálise da governança na implementação do modelo comunitário de saúde mental no Chile]

El presente artículo describe y analiza el rol que ha jugado la gobernanza en el desarrollo del modelo comunitario de salud mental en Chile. Se describen y analizan cinco dimensiones de la gobernanza: 1) el desarrollo de una serie de estrategias para favorecer la participación de los usuarios de servicios de salud mental ha logrado resultados insuficientes; 2) la implementación de tres planes nacionales de salud mental, que han mantenido la misma visión estratégica a lo largo de tres décadas, han contribuido a aumentar la accesibilidad a la atención comunitaria de las personas con enfermedades mentales y disminuir el rol de los hospitales psiquiátricos; 3) la inexistencia de una ley de salud mental persiste aún como un desafío, aunque haya sido parcialmente compensada por distintas leyes y decretos; 4) las regulaciones en la asignación de los recursos financieros, la formación del recurso humano y las directrices técnicas han contribuido a mejorar el acceso y la calidad de la atención; y 5) la construcción progresiva de un sistema de información en salud mental ha permitido conocer principalmente las tasas de acceso, las brechas de tratamiento y las inequidades geográficas. La experiencia chilena confirma la importancia de aplicar un conjunto de estrategias y mecanismos de gobernanza, para favorecer el desarrollo y el funcionamiento de los servicios de salud mental. El tipo de estrategias y mecanismos de gobernanza podrán variar en los distintos países según los contextos y las ventanas de oportunidades.

[Mental health response capacity in primary care in Chile: a contribution to Alma-AtaCapacidade de resposta da atenção primária em saúde mental no Chile: uma contribuição de Alma-Ata]

This article identifies strategies that have contributed to the development of mental health response capacity in primary care in Chile and analyzes some lessons learned from this process. It highlights the formulation of national mental health plans, the gradual development of an information system, the investment of additional resources, the creation of programs and guidelines, human resources development, the positioning of mental health in integrated health service delivery networks, support for biopsychosocial child development, the family and community care model, and the strengthening of leadership and partnerships between health and human services.Its indicators of response capacity are the increase in resources for mental health in primary care, both financial and staffing (that is, the number of professionals and the training provided to them), and the expansion of mental health treatment in primary care settings, notably the rate of people in treatment for mental illness and the support provided for child development.The article analyzes different factors that have contributed to advances in primary care delivery of mental health services, together with some weaknesses in this process. It concludes by demonstrating the feasibility of progress toward the goals of Alma-Ata to other countries in the Region, gradually implementing substantial changes in mental health response capacity in primary care. To this end, it recommends an improvement in the quality and quantity of research in this area through methodologies that permit comparisons between countries in the Region.

Implementing a Community Model of Mental Health Care in Chile: Impact on Psychiatric Emergency Visits

OBJECTIVE

The community model of mental health care (CMMHC) is recommended as the best way to organize mental health care, but evidence of its successful implementation and effectiveness is scarce, particularly in resource-poor settings. This study aimed to evaluate the impact of CMMHC on the rate of psychiatric emergency visits in Santiago, Chile.

METHODS

The rate of psychiatric emergency visits from 2006 to 2011 was compared between two health care administrative districts: district 1 (D1), in which CMMHC was being systematically implemented, and D2, where CMMHC implementation was very limited and inconsistent. In addition, rates of psychiatric emergency visits in ten D1 municipalities were compared by the degree to which they had implemented CMMHC.

RESULTS

Compared with D2, D1 had higher rates of psychiatric emergency visits during the observation period. In D1, the rate of visits per 100,000 inhabitants declined from 541 in 2006 to 414 in 2011. In D2, the rate increased from 104 in 2006 to 130 in 2011. In D1 municipalities, the reduction in the rate of psychiatric emergency visits was greater in those with well-implemented CMMHC compared with those with partially implemented CMMHC. When distance to the emergency room was taken into account, the 2011 rate of emergency visits in the ten D1 municipalities was 21% (p<.01) lower in those with well-implemented CMMHC than in those with partially implemented CMMHC.

CONCLUSIONS

CMMHC implementation leads to reduction in psychiatric emergency visits, which are burdensome to both users and providers. Results support CMMHC implementation in resource-poor settings.

Stigma and psychiatric care in Latin America: its inclusion on the universal health coverage agenda

In 2014, the Pan American Health Organization (PAHO) approved Resolution CP53.R14, which aimed to provide a framework for universal access to health and universal health coverage. It sets the stage for the inclusion of psychiatric practice within the provision of universal healthcare and highlights the fight against stigma. We propose to concentrate our efforts on changing the model of medical management. To that end, we are promoting the inclusion of mental health patients within the daily routine of primary care centres, thus allowing them to interact with other users of health services on a regular basis.

[Pathway to care of people with first episode of schizophrenia, in Chile]

BACKGROUND

It has been considered that the duration of first episode of psychosis is a critical period influencing the clini-cal and psychosocial evolution in people with diagnosis of schizophrenia. However, there is little knowledge about this issue in Low and Middle Income Countries.

OBJECTIVE

To describe the clinical characteristics and contacts with health services of people with first episode of schizophrenia, prior to their diagnoses and initiation of treatment. Sources and methods. The sample included all persons with diagnosis of first episode of schizo-phrenia, in five psychiatric care centers, located in the North, Center and South of Chile. Diagnosis was confirmed with ICD-10 criteria and psychopathology symptoms were explored using PANSS.

RESULTS

The sample was constituted by 48 patients (79.2% men, average age in 23.4 years). The symptom of depression was the first to appear (me-dian of 15 months, before diagnosis). Positive symptoms started in the previous year before diagnosis (delusions, median of 6 months). Positive symptoms triggered the first contact in 77.1% of the patients. Of these cases, 91.7% had medical care in this period (in Primary Health Care Centers and Mental Health Centers). The me-dian for previous contacts was 3.5, but the correct diagnosis was not done at that time.

CONCLUSION

Most of the patients had medical contacts for their psychotic symptoms, but their diagnosis were not made within that period, delaying the start of treatment. There is a need to develop strategies to improve diagnosis capabilities in these centers.

Psiquiatría de enlace en servicios médico-quirúrgicos de dos hospitales de Santiago

BACKGROUND

Medical and surgical teams consult psychiatrists when abnormal behavior or psychopathological traits are observed in their patients.

AIM

To describe the experience of liaison psychiatry teams in public hospitals.

MATERIAL AND METHODS

Analysis of 128 consultations, involving 110 patients. Eighty eight patients were subjected to the structured Clinical Interview for DSM-IV-TR Axis I Disorders--Patient Edition, the Mini Mental State score and to a search for personality disorders.

RESULTS

The most commonly consulted problems were depression in 44 patients, substance abuse in 29 and suicidal behavior in 21. The psychiatric study detected that 8% of patients were asymptomatic, 8% had stress reactions, 16.5% had substance abuse, 14.6% had alcohol abuse, 11% had a major depression, 10% had delirium or dementia, 9% had anxiety disorders, 4% schizophrenia, 18% personality disorders and 19% had suicidal behaviors.

CONCLUSIONS

Psychiatric consultations in medical and surgical services are common and have a wide variety of severity.

Asthma mortality in Latin America

There are not enough data concerning asthma mortality in Latin America. The Latin American Society of Allergy and Immunology coordinated this project to provide reliable data for gaining knowledge about our present situation, which is a condition indispensable to changing it. The following countries participated in this study: Argentina, Brazil, Chile, Colombia, Costa Rica, Cuba, Mexico, Paraguay, Peru, Uruguay and Venezuela. A uniform protocol was designed in Santa Fe, Argentina. Asthma mortality rates were analyzed in accordance with two variables: age-adjusted rates (5-34) and total death rates. The total population studied was 107, 122, 529 inhabitants. The highest death rates were found in Uruguay and Mexico (5.63), and the lowest in Paraguay (0.8) and Colombia (1.35). Age-adjusted (5-34) rates were higher in Costa Rica (1.38) and lower in Chile (0.28). Regarding sex, the analysis of the information provided by seven countries showed a predominance of females (51.8%) over males (48.18%). In the southern Latin American countries such as Chile, Uruguay, Paraguay and Argentina, which have marked climatic differences, deaths occurred mainly in the winter. It is important to emphasize that, in most countries, deaths from asthma occurred at home: Chile (60.7%), Argentina (63.4%) and Paraguay (88%). However, in Uruguay, 58.6% occurred during hospitalization. Mortality rates from bronchial asthma are high in most of the Latin American countries studied, even though further studies are needed. Asthma is a serious global health problem. People of all ages in countries throughout the world are affected by this chronic airway disorder that can be severe and sometimes fatal. The health ministries of each country do not believe asthma is a significant issue. Therefore, we should provide them with sound epidemiological studies to convince them to change their attitude toward this disease.

[Study of volume and kinetics of gallbladder emptying in non-pregnant, pregnant, and puerperal women]

Gallbladder stasis apparently plays an important role in the patho-genesis of cholelithiasis during pregnancy. On the other hand, gallstones diagnosed immediately after delivery disappear spontaneously during late puerperium in one third of these patients. Gallbladder emptying was assessed by biliary scintigraphy and ultrasonography in normal, nulliparous volunteers. The two methods had an excellent correlation: thence, we used ultrasonography to determine gallbladder volume and contraction in pregnant and puerperal women. Fasting and postprandial residual volumes were significantly larger during pregnancy, while the kinetics f gallbladder emptying was similar in nulliparous and pregnant women. During puerperium, gallbladder volume returned to the values observed in nulliparae; but the kinetics of emptying was significantly faster, suggesting an increased sensitivity of gallbladder muscle to physiologic stimuli.

[Chylous ascites in newborn infants]

Chylous ascites was recognized by abdominal ultrasonography in a 37 week gestational age newborn girl presenting with early transient respiratory distress syndrome, hypoglycemia and progressive abdominal distension. Diagnosis was confirmed by abdominal puncture. Treatment was focussed on dietary management which included oral amino acids, vitamins, medium chain triglycerides, maltose-dextrin; commercial rice starch and cane sugar and was followed by complete recovery at age two months.

[Massive ascariasis of the bile ducts and posterior relapse]

A 7 year old girl presented with persistent right upper abdominal colicky pain, fever, elevated white blood cells count, high blood sedimentation rate and mild liver enlargement. At surgical exploration 33 live ascarides (ascaris lumbricoides) were taken off from the hepatic duct. Medical treatment with mebendazole was given in full doses after surgery. She remained well for six years except for intermittent episodes of colicky right upper abdominal pain. At age 13 year ascarides were again demonstrated at the common biliary duct by abdominal echography. A second operation was necessary to eliminate parasites from the lower biliary tree, together with medical treatment for the patient and her family. One year later she was free of symptoms.
