Treatment of severe amitriptyline intoxication with plasmapheresis.

Tricyclic antidepressant poisoning is one of the most common causes of serious intoxication. Here, we report a 2-year-old girl with severe amitriptyline (70 mg/kg) intoxication. She was in comatose, had generalized tonic clonic seizure, ventricular tachycardia, and wide QRS complexes. Although she did not respond to classical therapies, very good clinical response to plasmapheresis was obtained and she developed no complications. Thus, plasmapheresis may be an effective treatment modality in poisoning with drugs, which bind to plasma proteins with high affinity.

Acute tetraventricular hydrocephalus caused by mumps meningoencephalitis in a child.

Mumps is one of the common causes of childhood aseptic meningitis and encephalitis. Although central nervous system involvement is a common manifestation, hydrocephalus is a very rare complication of mumps, with just a few cases reported in the literature to date. Here we report on an 8-year-old boy with acute tetraventricular hydrocephalus caused by mumps meningoencephalitis and treated by external ventricular drainage and following ventriculoperitoneal shunt.

The effect of treatment with montelukast on levels of serum interleukin-10, eosinophil cationic protein, blood eosinophil counts, and clinical parameters in children with asthma.

Interleukin (IL)-10 is an important immunoregulatory and anti-inflammatory cytokine. IL-10 levels are reduced in asthmatic airways. A regulatory mechanism involving IL-4 induced allergen-specific IL-10 production may be defective in allergic subjects, and this defect potentially contributes to more intense inflammation. The aim of this study was to define the effect of treatment with montelukast on serum levels of IL-10, eosinophil cationic protein (ECP), blood eosinophil counts, and clinical parameters (symptom score and lung function tests) in children with mild and moderate persistent asthma. Twenty-five children with mild-to-moderate persistent asthma and 25 nonatopic healthy children as controls were enrolled in the study. Patients were treated with montelukast for four weeks. Lung function tests for forced expiratory volume in 1 second (FEV1), peak expiratory flow (PEF), and forced expiratory flow between 25% and 75% (FEF25-75) were performed before and after treatment. Serum IL-10, ECP levels, and blood eosinophil counts were determined in both the control group and asthmatic children before and after treatment. The mean serum IL-10 levels were significantly lower before treatment than after treatment (1.75 +/- 0.9 pg/ml and 5.49 +/- 3.6 pg/ml; p < 0.001) and in control subjects (5.6 +/- 2.8 pg/ml). After four weeks of treatment with montelukast, the mean blood eosinophil count value (608 +/- 73/mm3 and 469 +/- 57/mm3; p < 0.05) but not the ECP value (33.98 +/- 24.3 microg/L and 29.03 +/- 19.2 microg/L; p > 0.05) was significantly decreased. After treatment with montelukast, all clinical parameters and lung function tests improved. We found no statistical correlations between the serum level of IL-10 and the serum level of ECP, eosinophil count, lung function tests, or clinical scores after treatment with montelukast. Montelukast caused a statistically significant increase in serum IL-10 levels and decrease in peripheral blood eosinophil counts over the four-week treatment period. Our study indicates that montelukast provides clinical benefits for children with chronic asthma and produces an anti-inflammatory response by increasing serum IL-10 levels,

Particulate matter (PM(2.5), PM(10-2.5), and PM(10)) and children's hospital admissions for asthma and respiratory diseases: a bidirectional case-crossover study.

Epidemiological studies reported adverse effects of air pollution on the prevalence of respiratory diseases in children. The purpose of this study was to examine the association between air pollution and admissions for asthma and other respiratory diseases among children who were younger than 15 yr of age. The study used data on respiratory hospital admissions and air pollutant concentrations, including thoracic particulate matter (PM(10)), fine (PM(2.5)), and coarse (PM(10-2.5)) particulate matter in Zonguldak, Turkey. A bidirectional case-crossover design was used to calculate odds ratios for the admissions adjusted for daily meteorological parameters. Significant increases were observed for hospital admissions in children for asthma, allergic rhinitis (AR), and upper (UPRD) and lower (LWRD) respiratory diseases. All fraction of PM in children showed significant positive associations with asthma admissions. The highest association noted was 18% rise in asthma admissions correlated with a 10-microg/m(3) increase in PM(10-2.5) on the same day of admissions. The adjusted odds ratios for exposure to PM(2.5) with an increment of 10 microg/m(3) were 1.15 and 1.21 for asthma and allergic rhinitis with asthma, respectively. PM(10) exerted significant effects on hospital admissions for all outcomes, including asthma, AR, UPRD, and LWRD. Our study suggested a greater effect of fine and coarse PM on asthma hospital admissions compared with PM(10) in children.

Community-acquired infection due to Stenotrophomonas maltophilia: a rare cause of septic arthritis.

Stenotrophomonas maltophilia is an important nosocomial pathogen in hospitalized patients, particularly those with prior broad-spectrum antibacterial therapy. The microorganism mainly infects severely ill, debilitated patients and is most frequent in immunocompromised hosts. A prominent feature of this organism is its resistance to multiple antibiotics including beta-lactam agents, carbapenems and aminoglycosides. Community-acquired infection with Stenotrophomonas maltophilia is reported rarely. This is the first report of a child patient diagnosed with septic arthritis due to Stenotrophomonas maltophilia.

[Massive parapneumonic effusion caused by Mycoplasma pneumoniae in a child: a case report]. / Mycoplasma pneumoniae'ya bagli yogun parapnömonik efüzyonlu bir olgu sunumu.

Mycoplasma pneumoniae infection is usually mild course and self-limited. Parapneumonic effusion is not a common feature of M. pneumoniae. The treatment of parapneumonic effusion is macrolides and chest tube with adequate pleural drainage. We report here on a child with M. pneumoniae infection complicated by massive parapneumonic effusion. Protracted course of fever and respiratory distress was noted in patient. Pneumothorax was occurred subsequent to chest tube drainage.

Youngest netherton patient with infantile asthma.

Netherton syndrome is a very rare disorder characterized with icthyosis, atopy, bamboo hair and intermittant aminoaciduria. The specifity of clinical and histopathological features of netherton syndrome is low in neonates and young infants who presents with predominating erythrodermia. Being the youngest infant presenting with the symptoms of infantile asthma we found it worth to report a six months old girl presenting with the feature of severe respiratory distress, generalized erythrodermia, and brittle hair.

Severe hypermagnesemia as a result of excessive cathartic ingestion in a child without renal failure.

A 14-year-old girl was referred to our hospital with lethargy and hypotension and was found to have a serum magnesium level of 14.9 mg/dL after having received an magnesium hydroxide (Magnesie Calcinee) for 7 days because of constipation. She was lethargic, her blood pressure was 70/40 mm Hg, and electrocardiogram revealed prolonged corrected QT interval and first-degree atrioventricular block. She has no renal dysfunction. Emergency hemodialysis after her condition ameliorated, her serum magnesium levels returned to normal. The present case suggests that massive oral magnesium ingestion with severe constipation and ileus may result severe hypermagnesemia without renal dysfunction.

Experience with cefepime versus meropenem as empiric monotherapy for neutropenia and fever in pediatric patients with solid tumors.

A prospective, open-label, randomized, comparative study in pediatric cancer patients was conducted to evaluate the efficacy and safety of cefepime and meropenem in the empiric therapy of febrile neutropenic patients. Febrile episodes were classified as microbiologically documented infection, clinical documented infection, or fever of unknown origin. Clinical response to therapy was classified as success or failure. In this period 37 children with solid tumors including lymphoma, 25 males, 12 females, had neutropenia on 65 occasions. Microbiologically documented infections occurred in 21 episodes (32.31%). Frequency of positive bacteria isolated was higher than gram-negative bacteria. There was no infection-related death. There were no statistical differences between the cefepime and meropenem groups for duration of fever or neutropenia, response rate, and necessity for modification. Cefepime appears to be as effective and safe as meropenem for empiric treatment of febrile episodes in neutropenic pediatric cancer patients.

Pseudotumour cerebri in children: etiological, clinical features and treatment modalities.

To investigate the etiological and clinical features of pseudotumour cerebri (PTC) in children, features of 12 children with PTC were documented. The etiology could be clarified in 6 patients. The other 6 patients were accepted as idiopathic intracranial hypertension (primary PTC). Acetazolamide was used as the first drug and was effective in only 4 patients who had no underlying cause. Repeated lumbar punctures (LP) were performed in 6 patients and 5 of them were unresponsive. Prednisone was used in 3 patients and was effective in only one patient. The CSF pressure continued to be high in five patients and could be normalized only by withdrawing of the precipitating drug in three patients and by ventricular-peritoneal shunting in two patients with cerebral venous thrombosis. Although, medical treatment and repeated LP are usually effective in children with PTC, clarifying and solving the underlying cause can be crucial.
