ABSTRACT
Es posible detectar normoblastos en los frotis de sangre periférica de los recién nacidos. En general, la cantidad de normoblastos por cada 100 leucocitos está en el intervalo de 0 a 10. Se observan con más frecuencia de lo usual ante una situación de hipoxia porque la hipoxia intrauterina aumenta la producción de eritrocitos. Sin embargo, no se había informado antes un caso de normoblastos multinucleados en un recién nacido a causa de la hipoxia. Presentamos el caso de un recién nacido con normoblastos multinucleados secundarios a hipoxia intrauterina. Este caso es importante porque es la primera vez que se han detectado normoblastos multinucleados en el frotis de sangre periférica de un recién nacido hipóxico.
Normoblasts may be seen in peripheral blood smear of newborns. The number of normoblasts per 100 white blood cells is generally in the range of 0-10.They can be seen more common than usual in hypoxic condition, because intrauterine hypoxia increases the production of red blood cells. However, multinucleated normoblasts in a newborn caused by hypoxia haven't been reported before. We present a newborn with multinucleated normoblasts secondary to intrauterine hypoxia. This case is important; because it is the first time multinucleated normoblasts in peripheral blood smear of a hypoxic newborn has been detected.

La gangrena gaseosa, o mionecrosis clostridial, es una de las enfermedades infecciosas más graves, y se caracteriza por la rápida y progresiva destrucción de los tejidos blandos profundos y la producción de gas dentro de los tejidos. Presentamos un caso de gangrena gaseosa espontánea mortal causada por Clostridium perfringens en un paciente con leucemia linfocítica aguda durante la fase de quimioterapia de inducción de la remisión.
Gas gangrene, clostridial myonecrosis, is one of the most serious infectious diseases, characterized by rapidly progressive destruction of deep soft tissues and production of gas within the tissues. We presented a case of fatal spontaneous gas gangrene due to Clostridium perfringens in a patient with acute lymphoblastic leukemia during remission induction chemotherapy phase.

La sarcoidosis, un trastorno multiorgánico de etiología desconocida que afecta varios órganos, es poco frecuente en los niños. Se desconocen la incidencia y la prevalencia reales de la sarcoidosis infantil. Al igual que en los adultos, muchos niños con sarcoidosis tal vez no presentan síntomas y la enfermedad cursa sin diagnosticarse. Es fundamental realizar una evaluación completa y sistemática del paciente para establecer el diagnóstico de sarcoidosis en los niños. Se describe el caso de una nina de 12 años con uveítis y hepatoesplenomegalia de dos años de evolución. Mediante una tomografía computarizada del tórax, se hallaron nódulos pulmonares periféricos dispersos y linfadenopatía hiliar bilateral. La aspiración de médula ósea y la biopsia de hígado no fueron diagnósticas. La biopsia de pulmón mostró granulomas de células epitelioides no necrosantes. A la paciente se le diagnosticó sarcoidosis en virtud del hallazgo de inflamación granulomatosa y de la exclusión de entidades confusoras.
Sarcoidosis, a multisystem disorder of unknown etiology that involves multiple organs, is rare in children. The true incidence and prevalence of childhood sarcoidosis is unknown. As in adults, many children with sarcoidosis may be asymptomatic; the disease may remain undiagnosed. A complete and systematic evaluation of the patient is essential for the sarcoidosis diagnosis in children. Here, we describe a case of 12-year-old female who presented with 2 years history of uveitis and hepatosplenomegaly. A chest computerized tomography revealed scattered peripheral pulmonary nodules and bilateral hiliar lymphadenopathy. Bone marrow aspiration and liver biopsy were not diagnostic. A lung biopsy showed non-necrotizing epithelioid cell granulomas. She was diagnosed with sarcoidosis according to demonstration of granulomatous inflammation and the exclusion of confusable entities

OBJECTIVE: To determine the incidence of iron deficiency in children with CCHD by noninvasive, inexpensive and easy laboratory methods. METHODS: Forty four children with cyanotic congenital heart disease (CCHD), aged 6 to 48 months were included in this study. The patients were categorized as iron deficient (n:28) and iron sufficient group (n:16). Children with CCHD who had iron deficiency were treated with iron for 3 months. RESULT: Iron sufficient patients were followed during 3 months without giving iron preparation. Mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), red cell distribution width (RDW), serum iron (SI), total iron binding capacity (TIBC) and serum ferritin levels were measured in all patients at the beginning and at the end of the study. CONCLUSION: In children with CCHD, hemoglobin (Hb), hematocrit (Hct) and red blood cell (RBC) counts were not considered significant parameters in the diagnosis of iron deficiency. Determination of MCV, MCH, RDW values is relatively easy and inexpensive method requiring small amount of blood for the diagnosis of iron deficiency during the follow-up of patients with CCHD.

OBJECTIVE: Intoxication is one of the most common causes of admissions to emergency department in pediatric age group. Incidence of iron poisoning gradually increased because of wide spread use of iron containing drugs. METHOD: In this report, we present five cases of iron ingestion who were admitted to our emergency department within a year. RESULT: Whole bowel irrigation in addition to gastric lavage with an iron dose of over 50 mg/kg as well as deferoxamine treatment for patients in whom clinical and laboratory indications are present. CONCLUSION: The prompt recognition and treatment of children with acute iron poisoning is the single and the most critical point for decreasing the morbidity and mortality associated with iron containing products.
