Dengue en paciente de 32 días de vida. Reporte de un caso poco habitual / Dengue fever in a 32-day-old patient. A rare case report

El dengue es una enfermedad viral transmitida por la picadura del mosquito Aedes aegypti. El comportamiento del dengue en Argentina es epidémico; la mayoría de los casos se observan en los meses de mayor temperatura. Hasta la semana epidemiológica (SE) 20/2023, se registraron en Argentina 106 672 casos; se vieron afectadas 18 de las 24 provincias que conforman el país. Dentro de los principales grupos de riesgo, se incluyen los menores de 2 años. Reconocer los signos, síntomas e identificar los factores de riesgo es fundamental para el manejo de casos con mayor riesgo de gravedad. Presentamos el caso de una paciente de 32 días de vida que se internó por síndrome febril sin foco, con diagnósticos diferenciales de meningitis viral y sepsis, evolucionó con leucocitosis, plaquetopenia, hipoalbuminemia, asociado a exantema y edemas. Se llegó al diagnóstico de dengue por la clínica, epidemiologia e IgM positiva.

Dengue fever is a viral disease transmitted by the Aedes aegypti mosquitoes. In Argentina, dengue fever is an epidemic disease; most cases are reported during the hot months.Until epidemiological week (EW) 20/2023, 106 672 cases were reported across 18 of the 24 provinces of Argentina. Children younger than 2 years are among the main groups at risk. Recognizing signs and symptoms and identifying risk factors is fundamental for the management of cases at a higher risk of severity. Here we describe the case of a 32-day-old female patient who was hospitalized due to febrile syndrome without a source, who had a differential diagnosis of viral meningitis and sepsis and progressed to leukocytosis, thrombocytopenia, hypoalbuminemia in association with rash and edema. The diagnosis of dengue fever was established based on clinical, epidemiological, and positive IgM data.

Higiene alimentaria para la prevención de trastornos digestivos infecciosos y por toxinas / Food safety for the prevention of the infecious and toxine of the foodborne diseases

El principal factor que interviene en el origen y prevención de las enfermedades trasmitidas por los alimentos es la higiene alimentaria. Dichas enfermedades son causadas por la ingestión de alimentos o agua contaminados con microorganismos patógenos ocasionando una infección o por la ingestión de alimentos contaminados con toxinas. Los principales agentes involucrados son Escherichia Coli, Campylobacter, Salmonella, Shigella, Listeria Monocytogenes, Norovirus, virus Hepatitis A, Astrovirus, Rotavirus, y Virus Coxsackie. Toxinas producidas por hongos o por microflora marina y los contaminantes orgánicos persistentes pueden también causar serios problemas de salud. La inocuidad alimentaría ha tomado relevancia debido a una mayor exigencia por consumidores cada día más informados y por las demandas del comercio exterior. Medidas que aseguren una adecuada higiene alimentaría nos permitirá prevenir enfermedades, principalmente digestivas, causadas por variados agentes en los alimentos. Esto se logra por la implementación de las medidas propuestas por la Comisión Internacional conocida como Codex Alimentarius

Food Safety is the main factor involved in the origin and prevention of Food-borne diseases. These diseases are caused by either the intake of contaminated foods or water or by the intake of toxin-contaminated foods. Escherichia Coli, Campylobacter, Salmonella, Shigella and Listeria Monocytogenes, Norovirus, Hepatitis A virus, astrovirus, rotavirus, and coxsackie virus are the main causative agents involved in food-borne diseases. Toxins produced by fungi or marine microflora and the presence of persistent organic polluting agents can also cause serious health problems. Food safety has become an important topic due to a more demanding and informed consumer and the foreign food trade. Measures leading to ensure a better food safety will allow us to prevent various foodborne preventive diseases, mostly in the digestive system, caused by different etiological agents. This can be achieved through the implementation of the different measures proposed by the international commission called Codex Alimentarius

Evaluación de un programa piloto de intervención en adultos con sobrepeso u obesidad, en riesgo de diabetes / Evaluation of a pilot intervention program for overweight and obese adults at risk of type 2 diabetes

Background: The Ministry of Health of Chile and selected obesity specialized centers implemented an interdisciplinary pilot program for overweight adults at risk of diabetes to decrease the risk of type 2 diabetes (T2D) and cardiovascular risk factors (CVRF). Aim To assess the results of this program. Patients and methods: Beneficiaries of the public primary health system aged 18-45 years, with a body mass index (BMI) 25-38 kg/m² and fasting blood glucose 100-125 mg/dL or with any direct family member with T2D, were recruited. During the four months of the study, they were scheduled for three physician visits, four dietitian consultations, 14 physical activity sessions and four group workshops (two with a psychologist or therapist). In fasting blood samples, at the beginning and at the fourth month, glucose, insulin and lipids were determined. The Homeostasis model assessment (HOMA) index was calculated. Results: Two hundred-seventy-six patients were recruited and 160 (141 women), completed the four months of follow up. In this subgroup, at the start and end of the intervention, a BMI equal to or greater than 30 kg/m² was observed in 69 percent and 52 percent of subjects respectively, a systolic blood pressure equal to or greater than 140 mm Hg was observed in 24 percent and 6 percent respectively, a diastolic blood pressure equal to or greater than 90 mm Hg was observed in 28 percent and 9 percent respectively, a blood glucose equal to or greater than 100 mg/dL was observed in 61 percent and 19 percent respectively, a plasma insulin equal to or greater than 12,5 fi Ul/rnl was observed in 49 percent and 34 percent respectively and a HOMA equal to or greater than 2.5 was observed in 63 percent and 42 percent respectively (all these comparisons are significant with a p <0.05). Conclusions: In those patients that completed the follow up period, this intervention induced a significant decrease of some CVRF, such as BMI, fasting glucose levels...
