ABSTRACT
La intoxicación por naftaleno es poco frecuente en los niños. Es causada por la ingesta, la inhalación o el contacto con la piel de sustancias que contienen naftaleno. Los pacientes suelen tener orina de color marrón oscuro, diarrea acuosa y vómito bilioso. Los signos incluyen fiebre, taquicardia, hipotensión y valores bajos en la oximetría de pulso, incluso con oxigenoterapia. Los análisis de sangre detectan anemia hemolítica, metahemoglobinemia, insuficiencia renal e hiperbilirrubinemia. Además del tratamiento sintomático, se hacen transfusiones de eritrocitos y se les administran ácido ascórbico, azul de metileno y N-acetilcisteína. En este artículo, presentamos el caso de un paciente masculino de 23 meses de edad con metahemoglobinemia y hemólisis intravascular aguda que recibió atención en la unidad de cuidados intensivos durante cinco días por intoxicación por naftaleno. Si bien la intoxicación por naftaleno es muy poco frecuente, tiene consecuencias mortales y se debe ejercer precaución con su uso y venta.
Poisoning by naphthalene is uncommon in children. It is a type of poisoning brought on by ingesting, inhaling, or coming into touch with naphthalene-containing substances on the skin. Patients typically present with an initial onset of dark brown urine, watery diarrhea, and bile vomit. The signs include fever, tachycardia, hypotension, and low pulse oximetry readings even with oxygen support. Hemolytic anemia, methemoglobinemia, renal failure, and hyperbilirubinemia are all detected in blood tests. Erythrocyte transfusion, ascorbic acid, methylene blue, and N-acetylcysteine (NAC) therapies are provided to inpatients in addition to symptomatic treatment. We present a 23-month-old male patient who developed methemoglobinemia and acute intravascular hemolysis, who was followed up in the intensive care unit for five days due to naphthalene intoxication. Although naphthalene poisoning is very rare, it should be known that it has fatal consequences, and more care should be taken in its use and sale.

La intubación convencional para la asistencia respiratoria en niños con vía aérea dificultosa puede ser un desafío incluso en manos expertas. Los rápidos avances en la atención respiratoria han reducido la incidencia de intubación traqueal dificultosa y por ende las complicaciones. Sin embargo, en algunos pacientes, todavía ocurren complicaciones graves inesperadas. Describimos el caso de un neonato con secuencia de Pierre Robin con vía aérea dificultosa, que presentó una migración del tubo endotraqueal hacia el esófago luego de haberse desprendido del conector del tubo. Deseamos compartir esta experiencia ya que, de acuerdo con nuestro conocimiento, esta complicación no ha sido comunicada anteriormente en neonatos.
Conventional intubation for pulmonary management in children with a difficult airway may be very challenging even in skilled hands. Rapid advancements in respiratory care have reduced the incidence of difficult tracheal intubation and the incidence of complications have decreased accordingly. However, serious unexpected complications still occur in some patients today. Herein, we describe a syndromic newborn infant with a difficult airway who experienced migration of the endotracheal tube into the esophagus after displacement of the tube connector. We would like to share our experience and contribute to the literature with the presentation of this undesired event. To the best of our knowledge, no such complication has been reported in the neonatal literature before.

To evaluate the possible protective effect of pomegranate extract [PE] on rats following renal ischemia-reperfusion [I/R] injury. Twenty-four Wistar rats were divided into three groups. Sham group underwent laparotomy then waited for 45 minutes without ischemia. I/R group were subjected to left renal ischemia for 45 minutes followed by 60 minutes of reperfusion. I/R + PE group were subjected to the same renal I/R as the I/R group were also given 225 mg/kg PE peroral 30 minutes prior to the ischemia. Malondialdehyde [MDA], total antioxidant capacity [TAC], total oxidant status [TOS], and oxidative stress index [OSI] were determined on the blood samples and kidney tissues. Histopathological analyses were conducted on the kidney tissues. Serum TAC levels were significantly decreased in I/R group when compared with S group [P = 0.001]. Serum MDA levels were increased in I/R group; however, it was not statistically significant. In rat kidney tissues, TOS levels and OSI index were significantly increased after I/R injury, while TAC levels were decreased. In I/R + PE group, PE reversed the negative effects of I/R injury. PE pretreatment was effective in decreasing tubular necrosis score. PE pretreatment ameliorated the oxidative damage and histopathological changes occurring following renal I/R injury

To compare tuboperitoneal factors of infertile women by hysterosalpingography [HSG] and laparoscopy. In this cohort study, 82 infertile cases were evaluated retrospectively by laparoscopy, 3 months subsequent to HSG in the Department of Gynecology and Obstetrics, Medical School of Dicle University, Diyarbakir, Turkey, between March 2004 and April 2006. The findings of HSG and laparoscopy were compared. Out of the 82 infertile women, pathological findings were observed in 45.1% by HSG, and 54.9% had no pathological finding. On laparoscopic evaluation, however, pathological findings were observed in 65.85%, and 34.15% had no pathological findings. The pathological findings were detected by laparoscopy in 20 of the 45[44.4%] patients who had no pathological findings by HSG, and no pathological findings were detected by laparoscopy in 3 of the 37 [8.1%] patients who had pathological findings by HSG. Laparoscopy revealed no pathological findings in 6 of the 35 patients who had tubal pathology by HSG. The sensitivity of HSG was 63%, specificity was 89.3%, and the positive predictive value was 92%, with a 55% predictive value, and the accuracy ratio was 72%. Laparoscopy is a superior method for the research of tubal and pelvic pathologies in the evaluation of infertility. However, HSG is a more economical and elementary method suitable for evaluation of endometrial and tubal pathologies, and laparoscopy is an appropriate method for examining the external part of tubae, fimbriae, the relation of tuba and ovary, endometriosis, adhesions, tuberculosis, and other pathologies. Therefore, these 2 methods are not alternative, but complementary

The aims of this study were to investigate the serum levels of some cytokines [tumor necrosis factor-alpha (TNF-alpha), interleukin 1ß (IL-1ß), IL-2R, IL-6, and IL-8] and nitric oxide (NO) levels in patients with untreated brucellosis and to test the correlation of these parameters with each other. The study was conducted on 67 subjects, 37 patients with brucellosis and 30 healthy individuals with no history of Brucella infection. Brucellosis was identified by a positive blood culture and/or increased Brucella antibodies in serological tests in addition to compatible clinical symptoms. Cytokine profile analysis was performed by the immulite chemiluminescent enzyme immunometric assay whose inter- and intra-assay coefficients of variance were 2.6-3.6 and 4.4-8.5 percent, respectively. The levels of nitrites/nitrates, which are representative of NO levels, were measured by the Griess method. Patients with brucellosis had significantly elevated serum levels of nitrites/nitrates, IL-2R, IL-6 and IL-8 (mean ± SD, 102.8 ± 23.8 æmol/l, 806.1 ± 58.5 U/ml, 21.1 ± 2.3 pg/ml, and 8.8 ± 1.6 pg/ml, respectively) compared to healthy controls, whereas TNF-alpha and IL-1ß levels were unchanged. No statistically significant correlation was detected between any of the studied cytokine levels and nitrate/nitrite concentrations according to Pearson's linear correlation test. We conclude that only IL-6, IL-8 and IL-2R are elevated in brucellosis and the extent of elevation depends on the severity and clinical pattern of the disease. Moderate elevation in serum NO was comparable to that observed in previous studies. This explains the absence or very rare occurrence of septic shock in brucellosis.
