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 Patients were all withdrawn from medications and valproic acid started at 250 mg or 500 mg daily.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.     

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.

     

The Effect of Renal Replacement Therapies on Serum Gastrointestinal System Hormones

Background. The kidney is a major site for the inactivation, degradation, and clearance of a variety of peptide hormones. It has been shown that the uremia increases or decreases gastrointestinal system (GIS) hormones. Moreover, studies investigating the serum GIS hormones levels in chronic renal failure (CRF) were conducted mainly in a particular period of the renal replacement therapy, and the changes caused by continuous ambulatory peritoneal dialysis (CAPD) and hemodialysis (HD) could not be fully demonstrated. In this study, we investigated the effect of CAPD and HD on serum GIS hormones (amylase, lipase, trypsinogen, and gastrin) levels in CRF patients who were diagnosed for the first time. Methods. Serum amylase, lipase, trypsinogen, and gastrin levels were measured in 36 patients who were just diagnosed with CRF, 22 patients with CAPD and 14 patients with HD. GIS hormones of these patients were measured before treatment and three months from the beginning of CAPD and HD treatment. As the control group, 20 normal healthy cases with well-matched age and gender were used. Results. The mean serum amylase, lipase, secretin, and gastrin levels were found meaningfully decreased according to the beginning values at third months of the CAPD and HD treatment. However, they were higher than control group. Conclusion. In patients receiving CAPD or HD as renal replacement therapy, GIS hormone levels were found to be lower, albeit higher than the healthy control group.     

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.
