Effect of valproic acid on withdrawal therapy in patients with overuse of chronic daily headache medications.

Discontinuation of medication is the treatment of choice for patients with chronic daily headache (CDH) who overuse their medications. This treatment may be difficult due to increased headache severity observed in patients immediately after withdrawal. We retrospectively evaluated the efficacy of valproic acid therapy in 66 patients with overuse of CDH medication during withdrawal therapy. Patients were all withdrawn from medications and valproic acid started at 250 mg or 500 mg daily. Forty-two (63.6%) patients had decreased headache severity, including 27.3% objective responses in the first week. At the last visit in the 12th week, 50 patients were headache-free and only one patient had persistent headache. Fifteen patients withdrew from therapy due to side effects and lost to follow-up within this timeframe. Thus, low dose valproic acid appears to be safe and effective in the management of withdrawal therapy.     

Renal resistive indexes and some renal functions in liver cirrhotic children

BACKGROUND: The aim of the present study was to investigate renal vascular resistive changes in children with different stages of liver cirrhosis without obvious renal failure. METHODS: Twenty-nine children (14 girls, 15 boys, mean age 11.6 years) with cirrhosis and 20 healthy children (mean age 10.3 years) were investigated for renal vascular resistance with Doppler ultrasonography, urinary sodium, N-acetyl-beta-D glucosaminidase (NAG) and microalbuminuria excretion. RESULTS: The measurements of renal resistive indexes (RRI) were significantly higher in cirrhotic patients than the control group (0.69 +/- 0.07 vs 0.62 +/- 0.02, P < 0.0001). RRI measurement was found to be increased in decompensated cirrhotic patients than in compensated cirrhotic patients (0.73 +/- 0.05 vs 0.67 +/- 0.08, P < 0.0001). A significant positive relationship was observed between RRI and child score (r = 0.53). Urine NAG/Cr ratio was significantly higher in cirrhotic patients than in the control subjects (P < 0.001). Microalbumin concentrations were increased in the patients with decompensated cirrhosis than in the controls (P = 0.02). Patients with ascites and portal hypertension showed increased RRI values. CONCLUSIONS: We conclude that patients with cirrhosis are at risk of renal deterioration, which can not be detected by serum urea, creatinine, and glomerular filtration rate. The increase of RRI is associated with the progress of hepatocellular disease, and also the development of ascites and portal hypertension. Elevated urinary sodium excretion, elevated urinary NAG/Cr ratio and microalbuminuria might have a prognostic value especially in patients with Child scores> 6. Hence, monitoring RRI is a non-invasive means of studying early renal hemodynamic alteration in childhood cirrhosis.     

Fanconi's aplastic anemia, analysis of 18 cases

A total of 18 patients within the age range of 5-13 years, 12 male and 6 female, are diagnosed as having Fanconi's aplastic anemia on the basis of congenital abnormalities, pancytopenia, bone marrow hypoplasia, and chromosomal and hematologic analysis. The hereditary and familial basis of Fanconi's aplastic anemia was apparent in this series. Common abnormalities were growth retardation, café au lait spots, hyperpigmentations, microcephaly, phalange deformities, mental retardation, and hypogenitalism; chromosome abnormalities were detected in the majority of our cases. Mast cells were observed in the bone marrow in most of the patients. 1 case developed acute myelomonocytic leukemia.     

A Rare Cause of Renovascular Hypertension: Takayasu Arteritis with Only Renal Artery Involvement

Takayasu arteritis is a chronic inflammatory disease that affects mainly the aorta, main branches of aorta, and pulmonary arteries with unknown etiology. Disease affecting solely the renal arteries is rare. We will present a case that had hypertension, hypokalemia, and metabolic alkalosis where the etiology was type 2 Takayasu arteritis, affecting renal arteries.     

CerebralDermabacter hominis abscess

Summary Dermabacter species are commonly isolated from the skin and other body sites but rarely show pathogenicity in humans. A case ofDermabacter hominis cerebral abscess is reported which presented as a contrast-enhancing intracranial mass in a renal tranplant patient.     

Safety and Efficacy of Intravenous Colistin in Neonates With Culture Proven Sepsis

Background:

Although it is well described among adults, intravenous colistin use and its associated toxicities in newborns are poorly understood.

Objectives:

We present our experience of efficacy and safety of intravenous colistin in the treatment of sepsis in term and preterm neonates.

Patients and Methods:

The records of neonates who received colistin between January 2013 and February 2014 were retrospectively reviewed. All neonates with culture proven nosocomial infections due to multidrug resistant organisms and treated continuously with colistin for more than 72 hours were included in the study.

Results:

Patients were evaluated for clinical and microbiological response to the drug and its and side effects. Twelve newborn infants with mean 31.8 ± 3.5 weeks gestational age and median 1482 (810 - 3200) gram birth weight were included. 11/12 (91.7%) patients showed microbiological clearance with intravenous colistin. One patient who had recurrent cerebrospinal fluid positive culture was treated with intraventricular colistin. The major side effects observed was hyponatremia and hypokalemia in 2 (16.6%) patients, all infants required magnesium supplementation.

Conclusions:

Intravenous colistin administration appears to be safe and efficacious for multidrug-resistant gram-negative infections in neonates, including preterm infants. However, we believe that large prospective controlled studies are needed to confirm its efficacy and safety in neonates.     

Adolescents’ somatic complaints in eight countries: what influence do parental rearing styles have?

Medically unexplained physical symptoms are frequently named by adolescents in both clinical and normative samples. This study analyzed the associations between parental rearing styles and adolescents’ body complaints in diverse cultural contexts. In a cross-cultural study of 2415 adolescents from eight countries (Argentina, France, Germany, Greece, Pakistan, Peru, Poland, and Turkey), the associations of maternal and paternal support, psychological control, and an anxious parental monitoring style with youth body complaints were tested. Girls reported more somatic complaints than boys, the level of complaints differed between countries, and gender differences varied significantly between countries. Hierarchic multilevel models revealed that the expression of distress via body complaints, after controlling for country, gender, and sociodemographic status, was significantly associated with parental rearing styles. The negative impact of mothers’ psychological control on body complaints generalize across countries. In addition, mothers’ anxious monitoring had a negative impact on the offspring’s health, whereas higher levels of paternal support and lower levels of paternal psychological control contributed to lower levels of somatic complaints. Sociodemographic variables such as family structure, standard of living, and employment status of the parents, did not turn out as significant in the final model. The findings point to the different roles of fathers and mothers play in adolescents’ health and their complex interplay.
