RESUMO

SETTING: In 2012, Peru's National TB Program (NTP) reported approximately 2400 incident cases of tuberculosis (TB) disease in children aged <15 years. Peru's TB burden is concentrated in the Lima metropolitan area, particularly in poor districts such as El Agustino and La Victoria, where this study was conducted. OBJECTIVE: To identify barriers to the treatment of childhood tuberculous infection and TB disease in Lima from the perspective of front-line providers and patients' families. DESIGN: We conducted 10 semi-structured focus groups with 53 purposefully sampled primary care providers, community health workers, and parents/guardians of pediatric TB patients. We also completed nine in-depth interviews with National TB Program administrators and pulmonologists specializing in TB. Two authors performed inductive thematic analysis and identified emerging themes. RESULTS: Four main treatment barriers emerged from the data: 1) dosing errors, 2) time- and labor-intensive preparation and administration of medications, 3) provider concern that isoniazid preventive therapy (IPT) generates isoniazid resistance, and 4) poor adherence to IPT. CONCLUSION: Our findings highlight the urgent need for child-friendly formulations, provider and parent/guardian education about IPT, and strategies to promote adherence to IPT, including support and supervision by health workers and/or regimens with fewer doses.

RESUMO

Neuromyelitis optica (NMO) is a severe demyelinating disease of the central nervous system, which preferentially attacks the optic nerve and spinal cord. It is associated with antibodies against aquaporin 4. Morbidity and mortality are higher than in multiple sclerosis and its treatment focuses on immunosuppressive drugs. Immunomodulators are contraindicated. We report a previously healthy 35-year-old man, presenting with NMO concomitantly with systemic lupus erythematosus. His evolution was torpid with three outbreaks in the 10 months after the diagnosis, requiring a first-line therapy with methylprednisolone and cyclophosphamide and then a second-line therapy with rituximab.

RESUMO

AO Type C Thoracolumbar fractures are the most complex and unstable spine injuries, with a high frecuency of neurological impairment. The goal of this study is to describe the clinical characteristics, management and outcome in worker’s compensation patients with type C AO thoracolumbar fractures that were surgically treated in our hospital between January 1994 and December 2004. We collected 88 patients, 68 of them had work related accidents. Four patients were discarded because of insufficient data. The median follow up was 58 months. Of the 64 patients evaluated (mean age 35.7 years), 94 percent were men. The most common mechanism of injury was height fall (41 percent). Associated injuries occurred in 80 percent of the patients (23 percent had another spine fracture). Neurological impairment was present in 64 percent, 22 percent had incomplete, while 42 percent had complete impairment. The majority of the patients presented a C3 AO thoracolumbar fracture (50 percent). The average preoperative time was 6 days (range 0-64). The mean time of surgery was 224 minutes (range 80-640). Only 9.3 percent of the patients required a complementary anterior approach. The median hospitalization time was 61 days (6-275) and the mean postoperative rest was 9.8 months (1.4-34). We had 11 acute complications and 6 delayed complications. Return to work occurred in 64 percent of the patients, while 59 percent was compensated. Among the patients presenting partial neurological impairment, 50 percent improved at least one degree in the Frankel scale.

Las fracturas tóracolumbares tipo C de la AO corresponden a las lesiones espinales más complejas e inestables, con una alta incidencia de compromiso neurológico. El objetivo del presente estudio es describir las características clínicas, manejo y evolución de los pacientes accidentados del trabajo, con fracturas tóracolumbares tipo C de la AO, operados en nuestro hospital. Revisamos en forma retrospectiva los casos entre enero de 1994 y diciembre de 2004. Recolectamos 88 pacientes, 68 de los cuales correspondían a accidentados del trabajo. Cuatro casos fueron eliminados por información incompleta. La mediana de seguimiento fue de 58 meses. De los 64 pacientes evaluados (edad promedio 35,7 años),el 94 por ciento eran hombres. El mecanismo de lesión más común fue caída de altura (41 por ciento). Un 80 por ciento de los pacientes presentaron lesiones asociadas (23 por ciento con fractura de columna a otro nivel). Un 64 por ciento ingresó con compromiso neurológico, de los cuales, el 22 por ciento fue parcial y 42 por ciento completo. La mayoría de las fracturas fueron tipo C3 de la clasificación AO (50 por ciento). El tiempo promedio preoperatorio fue de 6 días (0-64). La duración promedio de la cirugía fue de 224 minutos (80-640). Un 9,3 por ciento de los pacientes requirió de una vía anterior complementaria. La mediana de hospitalización fue de 61 días (6-275) y el tiempo promedio de reposo post operatorio fue de 9,8 meses (1,4-34 meses). Hubo 11 complicaciones precoces y 6 tardías. Un 64 por ciento retornó al trabajo y un 59 por ciento fue indemnizado. De los pacientes con compromiso neurológico parcial, un 50 por ciento recuperó al menos un grado en la escala de Frankel.

RESUMO

Leuconostoc is a gram-positive cocci, quite ubiquitous in nature. It is used in wine industry, and for aroma and texture of dairy products. Occasionally it has been isolated from humans in cases of bacteremia, catheter associated infections, sepsis, meningitis, pneumonia, UTI, osteomyelitis and hepatic dysfunction. Short bowel syndrome, patients with CVC and patients with gastrostomy undergoing enteral feeding, are described amongst the factors associated with this infection. The isolation of a gram-positive cocci, that does not hydrolyze arginine and that is resistant to vancomycin leads to this diagnostic possibility. Antibiotic treatment: penicillin or ampicillin.

Leuconostoc es una cocácea grampositiva parecida a los Streptococcus, que se encuentra ampliamente distribuida en la naturaleza; es usada en la industria de vinos, productos lácteos y quesos para la producción de aromas y texturas. Leuconostoc causa ocasionalmente infecciones en humanos, puede producir bacteriemia, infección asociada a catéter, síndrome séptico, meningitis, neumonía, infección del tracto urinario, osteomielitis y compromiso hepático, entre otros. Se describen como factores de riesgo para una infección por este agente: el síndrome de intestino corto, uso de catéter venoso central y la alimentación enteral por gastrostomía. Orientan a la presencia de este agente el aislamiento de una cocácea grampositiva, catalasa negativa, PYR y LAP negativas, resistente a vancomicina. El tratamiento de elección es penicilina o ampicilina.

RESUMO

Streptococcus agalactiae es el principal agente bacteriano responsable de la sepsis neonatal. Para evitar la infección perinatal se recomienda su pesquisa en la región vagino-anal durante el tercer trimestre, y tratamiento antibiótico durante el trabajo de parto en las gestantes colonizadas. El objetivo de este estudio es conocer la prevalencia de colonización del Streptococcus agalactie en la población de embarazadas controladas en la maternidad del Hospital Clínico de la Universidad de Chile, en el período comprendido entre el 1 de marzo y el 31 de mayo de 2003. Se tomó cultivo selectivo de Todd Hewitt, entre las 35 y 37 semanas de gestación a 185 embarazadas. Se determinó una prevalencia de colonización vagino-anal de 14,0 por ciento.

RESUMO

A scoring instrument to detect unwanted newborns was applied to 556 living-in women at a Santiago urban hospital in december 1987. Based upon previous research a scoring instrument including 10 items was designed and applied within 24 hours following delivery. According to the total score each newborn was classified as wanted (W), unwanted (U) or doubtful situation: 37.6% of children were born to unwed mothers. In a total of 556 children 4.5% (n = 25) were classified as U, 91.4% as W (n = 508) and 4.1% as doubtful (n = 23). Comparing U and W children the former had mothers with poorer education, higher frequency of bad relationships with their partners as well as higher proportion of three or more previous deliveries and late beginning of prenatal care (significant). On the other hand no significant differences were detected in age distribution of the mothers or their socio-economic level. The applicability of this scoring system and the magnitude and importance of the problem are analyzed and discussed. The need for further research on the natural history of the sequence unwanted pregnancy-unwanted child is stressed.
