Cyclosporine level at the second hour in pediatric hematopoietic stem cell transplant patients

In this retrospective study, cyclosporine levels at the second hour (C2 levels) were measured during oral cyclosporine intake in 28 pediatric hematopoietic stem cell transplant patients, and the relations between cyclosporine dosage and C0, C2 levels, C2/C0 ratio, and cyclosporine-related adverse effects were investigated. Cyclosporine levels at the second hour levels were found to be significantly lower in children younger than 7 years old, suggesting age-related differences in absorption and metabolism of the drug. There were statistically significant correlations of both C0 and C2 levels with blood creatinine values. In addition, a statistically significant negative relation was found between C0 and C2 levels and serum potassium levels; this unexpected finding was attributed to multiple drug effects in the early posttransplant period. The common adverse effects of cyclosporine (gingival overgrowth, gynecomastia, and hypertrichosis) were also evaluated in this study, and no correlation was found between those adverse effects and C0, C2 levels, C2/C0 ratio, and cyclosporine dosage. In the present study, despite the highly significant correlation of C2 levels with renal and metabolic effects, in pediatric hematopoietic stem cell transplant patients, measurement of C2 levels as a standard practice did not provide an advantage over C0 monitoring. However, the preliminary results suggest that C2 level monitoring could be useful in selected patients with increased risk of renal toxicity or in states where a better estimation of gastrointestinal absorption is needed.     

Increasing Low Birth Weight Rates: Deliveries in a Tertiary Hospital in Istanbul

Objective

Prevalence of low birth weight deliveries may vary across different environments. The necessity of determination of regional data prompted this study.

Methods

Information of all deliveries from January 2004 to December 2008 was obtained from delivery registry records retrospectively. Initial data including birth weight, vital status, sex, maternal age and mode of delivery were recorded using medical files. The frequency of low birth weight, very low birth weight, extremely low birth weight and stillbirth deliveries were determined.

Findings

Among 19,533 total births, there were 450 (23.04 per 1000) stillbirths. Low birth weight rate was 10.61%. A significant increase in yearly distribution of low birth weight deliveries was observed (P<0.001). Very low birth weight and extremely low birth weight delivery rates were 3.14% and 1.58% respectively. Among 2073 low birth weight infants, 333 (16.06%) were stillbirths. The stillbirth delivery rate and the birth of a female infant among low birth weight deliveries were significantly higher than infants with birth weight ≥2500g (P<0.001, OR=28.37), (P<0.001) retrospectively. There was no statistical difference between low birth weight and maternal age. The rate of cesarean section among low birth weight infants was 49.4%.

Conclusion

High low birth weight and stillbirth rates, as well as the increase in low birth weight deliveries over the past five years in this study are striking. For reduction of increased low birth weight rates, appropriate intervention methods should be initiated.     

Evaluation of ectodermal dysplasia

This case series report outlines possible cranio-maxillofacial deformation consequences associated with ectodermal dysplasia (ED) and embryonic malformations, including dental agenesis. Also described are the oral aspects and rehabilitation. A total of 14 ED patients (7 males and 7 females, aged 5-45 years) underwent clinical examination before assessment and treatment. Lateral cephalometric radiography, Steiner's analysis, and respiratory capacity tests were performed. Most of the patients had sparse or absent hair, a short face with an unusual facial concavity, a maxillary retrusion, and a relative mandible protrusion. Depending on age and orthopedic abnormalities, patients were treated with prosthodontic and orthodontic approaches or implant treatment. Therapists should take a comprehensive and multidisciplinary approach with these patients to improve their dental, masticatory, growth, and orthognathic conditions, as well as esthetic appearance.     

Erythrocyte deformability, plasma viscosity and oxidative status in patients with severe obstructive sleep apnea syndrome

BACKGROUND AND PURPOSE: In patients with severe obstructive sleep apnea syndrome (OSAS), diurnal changes of plasma viscosity and erythrocyte deformability were measured to elucidate the possible mechanism of cardiovascular diseases in OSAS patients. PATIENTS AND METHODS: Plasma viscosity and erythrocyte deformability was determined in 11 OSAS patients and 11 healthy subjects matched by sex and age. Plasma viscosity was measured by a cone-plate viscometer, and erythrocyte deformability was determined by filtration technique. Whole blood counts were performed and oxidative status of the patients' plasma and erythrocytes were evaluated. RESULTS: OSAS patients had higher plasma viscosity than controls, both in the morning (1.74+/-0.3 vs. 1.36+/-0.2 mPas, P<0.002) and evening (1.55+/-0.2 vs. 1.27+/-0.1 mPas, P<0.002), and morning plasma viscosity was significantly higher than the evening level (P<0.05). Morning plasma viscosity of patients was inversely correlated with their mean nocturnal SaO(2). Morning plasma malonyldialdehyde level was significantly higher in the patients than in the controls (69.7+/-30.5 vs. 45.5+/-11.0 nmol/l, P<0.005). Erythrocyte deformability of the patients was slightly lower. CONCLUSIONS: We have observed that plasma viscosity is high both in the morning and in the evening in severe OSAS patients. This elevation may predispose OSAS patients to myocardial infarction and stroke by increasing blood viscosity. Low nocturnal mean SaO(2) may be responsible for the high plasma viscosity in these patients.     

Intrabiliary rupture of hepatic hydatid cysts: diagnostic accuracy of MR cholangiopancreatography

OBJECTIVE: The purpose of this study was to establish the role of MR cholangiopancreatography (MRCP) in the diagnosis of biliary rupture in hepatic hydatid disease. We sought to determine whether the morphologic features of cysts and bile duct abnormalities detected on MRCP are specific enough for identification of intrabiliary rupture. CONCLUSION: If one of the following MRCP findings of apparent connection between hydatid cyst and biliary system, deformation of cyst, focal defect in cyst wall, or beaklike projection extending from cyst wall was present in a patient with hepatic hydatid cyst, the sensitivity of MRCP was 91.7% and the specificity was 82.8% for identification of intrabiliary rupture.     

Effect of strontium ranelate on fracture healing in rat tibia

ObjectivesVarious anti-osteoporotic agents are available for clinical use. In contrast to other anti-osteoporotic drugs, strontium ranelate has anti-resorptive and bone-forming effects (dual action). Our objective in the present study is to investigate the efficacy of strontium ranelate (SR) on fracture healing in rat tibia.MethodsForty-two male Wistar rats randomized into two groups (groups 1 and 2, n = 21 for each). Left tibiae of all animals were broken in a closed manner using a manual three-point bending technique through mid-tibia following deep anesthesia with ketamine. The animals in group 1 were fed 25 g/day specially produced food containing 450 mg/kg SR starting from the first post-operative day. Group 2 were given 25 g/day normal food. The animals were sacrificed on the 2nd, 3rd and 4th post-operative weeks (each week 7 animals were sacrificed from each group) and the broken tibiae were removed. The tibiae were examined first radiographically and second, histopathologically.ResultsRadiologically, callus maturity and bone union increased with time in both groups. But no significant differences were found regarding callus maturity and bone union in weekly comparisons (p = 0.52, p = 0.19, p = 0.74).ConclusionsHistopathologically, it was seen that the fractures remarkably healed steadily in both groups on the 2nd, 3rd and 4th post-operative weeks. But no significant differences were found regarding the progression of fracture callus in weekly comparison (p = 1.0, p = 0.52, p = 1.0).In the present study, we were unable to find any beneficial or harmful effects of strontium ranelate on fracture healing.     

Spondyloenchondrodysplasia with spasticity, cerebral calcifications, and immune dysregulation: clinical and radiographic delineation of a pleiotropic disorder

Enchondromas are a feature of several constitutional disorders of bone, and the classification of different nosologic entities is still provisional. Among these disorders, spondyloenchondrodysplasia (SPENCD), as outlined by Schorr et al. [1976], is defined by the presence of radiolucent spondylar and metaphyseal lesions that represent persistence of islands of chondroid tissue within bone. Careful review of radiographic findings is needed to distinguish SPENCD from the many other disorders combining enchondromas with spinal lesions. Even when strict criteria are applied, it appears that SPENCD is clinically heterogeneous, as some SPENCD patients are neurologically intact while others present with spasticity, mental retardation, and cerebral calcifications in different combinations, and it has been suggested that SPENCD should be divided in two types. We herein report ten individuals from six families with SPENCD and illustrate the radiographic changes. Seven individuals had CNS manifestations including spasticity, developmental delay, and late-onset cerebral calcifications. We also noted that six individuals had clinical manifestations of autoimmunity (auto-immune thrombocytopenic purpura, auto-immune hemolytic anemia, auto-immune thyroiditis, and SLE) and one had been diagnosed with immune deficiency. Neurological and autoimmune manifestations were seen in different combinations within one single family. These observations suggest that SPENCD may be a single entity defined by specific radiographic features, but with remarkably pleiotropic manifestations that include CNS disease (spasticity, mental retardation, and calcifications), as well as immune dysregulation ranging from autoimmunity to immunodeficiency. The notion of recessive inheritance hitherto assumed is challenged by the observation of two apparently dominant pedigrees.     

Small bowel metastases from primary carcinoma of the lung: Presenting with gastrointestinal hemorrhage

Upper gastrointestinal system bleeding should be first taken into account when a patient complains of melena. On rare occasions, gastrointestinal bleeding may be due to primary or metastatic tumors of the gastrointestinal system. Here, we present a case in which the localization of bleeding was demonstrated by Tc-99m red blood cell labeled scintigraphy with the final diagnosis of metastases of non-small cell lung cancer to the small bowel.     

Assessment of effects of pre- and post-training programme for healthcare professionals about breastfeeding

This retrospective study assessed the effects of pre- and post-training programme for healthcare professionals about breastfeeding. The study included 3,114 mothers who had children aged 1-72 month(s). Their knowledge and behaviours relating to breastfeeding were evaluated. The mothers were randomly divided into two groups: the 'before' group included 2,000 women who were not informed about breastfeeding, and the 'after' group comprised 1,114 women who had been informed about breastfeeding. 56.2% and 66.1% of the mothers started breastfeeding within 30 minutes after delivery, respectively, in the before and the after group (chi2 = 29.31, p < 0.001). 16.7% and 36.5% gave exclusive breastfeeding for six months (chi2 = 72.85, p < 0.001), and 28.5% and 23.7% stopped breastfeeding within the first five months (chi2 = 17.20, p = 0.002). Ninety-four percent delivered in a hospital or in a primary healthcare centre. Therefore, prenatal and postnatal breastfeeding education and support courses may improve a woman's chance of starting and continuing to breastfeed her baby. In terms of the number of antenatal check-ups, since the differences between the two groups were significant (chi2 = 390.67, p = 0.000), the importance of the training programme about breastfeeding was highlighted. Follow-up interventions after training are suggested.
