Magnetic resonance arthrographic demonstration of extension of labral defects in paraglenoid labral cysts

SUMMARY OBJECTIVE: This study aimed to investigate the extension of labral tears associated with paraglenoid labral cysts by magnetic resonance arthrography. METHODS: The magnetic resonance and magnetic resonance arthrography images of patients with paraglenoid labral cysts who presented to our clinic between 2016 and 2018 were examined. In patients with paraglenoid labral cysts, the location of the cysts, the relation between the cyst and the labrum, the location and extent of glenoid labrum damage, and whether there was contrast medium passage into the cysts were investigated. The accuracy of magnetic resonance arthrographic information was evaluated in patients undergoing arthroscopy. RESULTS: In this prospective study, a paraglenoid labral cyst was detected in 20 patients. In 16 patients, there was a defect in the labrum adjacent to the cyst. Seven of these cysts were adjacent to the posterior superior labrum. In 13 patients, there were contrast solution leak into the cyst. For the remaining seven patients, no contrast-medium passage was observed in the cyst. Three patients had sublabral recess anomalies. Two patients had rotator cuff muscle denervation atrophy accompanying the cysts. The cysts of these patients were larger compared to those of the other patients. CONCLUSION: Paraglenoid labral cysts are frequently associated with the rupture of the adjacent labrum. In these patients, symptoms are generally accompanied by secondary labral pathologies. Magnetic resonance arthrography can be successfully used not only to demonstrate the association of the cyst with the joint capsule and labrum, but also to reliably demonstrate the presence and extension of labral defects.

Efectos de la concentración de 25-hidroxi vitamina D sobre la gravedad y el control del asma en pacientes asmáticos en edad escolar / Effects of 25 hydroxy vitamin D levels on the severity and asthma control in school age asthma patients

Objetivo. Determinar la concentración de vitamina D en pacientes de entre 6 y 18 años de edad sometidos a un seguimiento por asma y la relación entre la concentración de vitamina D y el control y la gravedad del asma. Materiales y métodos. Se inscribió en el estudio a pacientes con asma y voluntarios sanos de entre 6 y 18 años de edad, asignados al grupo de pacientes y al grupo de referencia, respectivamente. Se registraron las características demográficas y los hallazgos clínicos de los pacientes, y se les realizó una prueba funcional respiratoria. Se estimaron el índice de masa corporal (IMC) y la concentración de 25-hidroxi vitamina D (25(OH)D), calcio, fósforo, fosfatasa alcalina, inmunoglobulina E total y eosinófilos de todos los pacientes. La gravedad del asma y las condiciones de control se determinaron según los criterios de la Iniciativa Global para el Asma (Global Initiative for Asthma, GINA). Resultados. Se incluyó a 72 pacientes con asma y a 66 niños sanos. En comparación con el grupo de referencia, en el grupo de pacientes se detectó una menor concentración de vitamina D. En 38 (52,8%) niños del grupo de pacientes con asma se observó deficiencia de vitamina D; en este grupo, el control del asma era deficiente y la gravedad, significativamente mayor. No se observó una correlación significativa entre la concentración de vitamina D y el sexo, la obesidad, las pruebas funcionales respiratorias, las pruebas cutáneas, la concentración sérica de eosinófilos e inmunoglobulina E (IgE) total. Conclusión. La deficiencia y la insuficiencia de vitamina D fueron más frecuentes en los niños con asma, en comparación con los niños del grupo de referencia. Una menor concentración de vitamina D se asocia con un control deficiente del asma y una mayor gravedad de esta.

Background. The objective was to determine vitamin D levels in patients between the ages 6 and 18 years, followed for asthma, and the relation between vitamin D levels and asthma control and severity. Materials and Methods. Patients with asthma and healthy volunteers between the ages 6 and 18 years were enrolled into the study as patient and control groups, respectively. Patient demographic information and clinical findings were recorded; a respiratory function test was performed. Body mass index (BMI), 25(OH) D,calcium, phosphorus, alkaline phosphatase, total IgE and eosinophil levels were determined for all patients. Asthma severity and control conditions were established based on GINA (Global Initiative for Asthma) criteria. Results. Seventy two patients with asthma and 66 healthy children were included. Compared to the control group, decreased serum vitamin D levels were detected in patient group. Thirty eight (52.8%) patients in asthma patient group had vitamin D defficiency; in this group, asthma control was poor and asthma severity was significantly higher. No significant correlation was found between vitamin D levels and gender, obesity, respiratory functions, skin test, serum eosinophil and total IgE levels. Conclusion. The frequency of vitamin D deficiency and insufficiency was higher in children with asthma, compared to the controls. Lower levels of vitamin D are associated with poor asthma control and increased asthma severity.

Evaluación de 200 pacientes pediátricos expuestos al riesgo de contraer rabia / Assessment of 200 pediatric patients exposed to rabies risk

Antecedentes/Objetivo: La rabia continúa siendo un grave problema de salud pública, especialmente en los países subdesarrollados o en vías de desarrollo. El objetivo de este estudio fue investigar las características demográficas y los programas de vacunación de los pacientes ingresados con diagnóstico presuntivo de rabia al Centro de Emergencias Pediátricas de nuestro hospital, que funciona como uno de los centros de vacunación antirrábica de nuestra provincia. Métodos: En este estudio, se analizaron retrospectivamente las historias clínicas de 200 pacientes ingresados al Centro de Emergencias Pediátricas con presunta exposición al virus de la rabia. Resultados: Entre los 200 casos, se halló que el riesgo de contraer rabia era mayor en el grupo de 5 a 9 años. El 68,5% de los casos tenían antecedentes de haber sido mordidos por un perro; el 29,5%, de haber sido rasguñados por un gato; y el 2%, de haber tenido contacto con otros animales. En el 76% de los casos se trataba de animales callejeros, solamente el 11% tenían dueño y habían sido vacunados, y estaban bajo supervisión. Se administró solamente la vacuna antirrábica al 42,5% de los pacientes ingresados, la vacuna antirrábica y la vacuna antitetánica al 51,5%, y la vacuna antirrábica, la vacuna antitetánica y concentrado de inmunoglobulinas antirrábicas al 6%. Se detectó que la profilaxis postexposición se había realizado según las recomendaciones en el 83,5% de los casos. Conclusión: La rabia continúa siendo un problema de salud pública grave en los países en vías de desarrollo, como el nuestro. Consideramos que es necesario sensibilizar a la sociedad; las autoridades locales deben esforzarse por luchar contra los animales callejeros y supervisar los servicios; el personal de la salud involucrado debe actualizarse mediante capacitaciones para reducir los casos de rabia.

Background/Purpose: Rabies is still an important health problem particularly in underdeveloped or developing countries. In this study, the aim was to investigate demographic characteristics and vaccination schedules of cases suspected of having rabies and admitted to the Pediatric Emergency Clinic of our hospital, which serves as one of the Rabies Vaccination Centers in our province. Methods: In our study, medical records of 200 patients admitted to the Pediatric Emergency Clinic with suspicion of risk of contact with the rabies virus were retrospectively analyzed. Results: Of those 200 cases, rabies risk was found to be greater in the 5-9 year old group. There was a history of having been bitten by dogs in 68.5% of cases, cat scratch in 29.5%, and contact with other animals in 2%. While 76% of animals were stray animals, only 11% of them had an owner and had been vaccinated, and were under supervision. Rabies vaccination only had been administered to 42.5% of admitted patients, tetanus and rabies vaccination to 51.5%, tetanus; rabies vaccination and human rabies immune globulin were administered to 6%. Post-exposure prophylaxis was found to have been given as recommended to 83.5% of cases. Conclusion: Rabies remains an important public health problem in developing countries Like ours. We consider that public awareness should be raised; local authorities should devote efforts to control stray animals and supervise such services, and updated guidance and training should be provided to the concerned health staff to reduce the risk of rabies.
