Choledochal cysts in children: evaluation with three-dimensional sonography

In this report, we describe the application of 3-dimensional (3D) sonography for diagnosing choledochal cysts in 3 girls who were 18 months, 2 years, and 11 years old. The 3D images that were obtained during the sonographic examination revealed that all 3 patients had a type I choledochal cyst and also demonstrated dilatation of the biliary tracts. The 3 patients then underwent surgical excision of their cysts, cholecystectomy, and hepaticojejunostomy. Besides its other clinical applications, 3D sonography promises to be a valuable adjunct to conventional 2-dimensional imaging for the evaluation of choledochal cysts in pediatric patients.     

Effects of honey as a scolicidal agent on the hepatobiliary system

AIM： To examine the effects of 10% diluted honey, which has been shown to be scolicidal, on the liver and biliary system and determine whether it could be used as a scolicidal agent in the presence of biliary-cystic communication. METHODS： Thirty Wistar-Albino rats were divided into two groups. Honey with 10% dilution in the study group and 0.9% saline （NaCI） in the control group were injected into the common bile ducts of rats through a 3-mm duodenotomy. The animals were sacrificed 6 mo alter the procedure. Histopathological, biochemical, and radiological examinations were performed for evaluation of side effects. RESULTS： At the end of the sixth month, liver function tests were found to be normal in both groups. The tissue samples of liver and ductus choledochus of the honey group showed no histomorphologic difference from the control group. No stricture on the biliary tree was detected on the retrograde cholangiograms. CONCLUSION： According to these results, we concluded that 10% diluted honey could be used as scolicidal agent safely in the presence of biliary-cystic communication.     

Comparison of Early and Late Changes in Immunoglobulins and Acute Phase Reactants after Laparoscopic Adjustable Gastric Banding in Patients with Morbid Obesity

Background

There are differences in the levels of inflammation mediators, lipids, and formed elements of the blood in morbidly obese patients compared with individuals of normal weight. In the current study, the change in these parameters was determined in patients who achieved weight loss by undergoing laparoscopic adjustable gastric banding (LAGB) by comparing preoperative, and early (3 months) and late (12 months) postoperative values.

Methods

The body mass index (BMI), weight, blood pressure, and waist circumference of 72 patients treated by LAGB procedures between September 2006 and February 2009 were measured and recorded. Pre- and postoperative 3- and 12-month C-reactive protein (CRP), immunoglobulin (Ig) G, IgA, IgM, fibrinogen (Fbg), complement components C3 and C4, total cholesterol, triglycerides, low-density lipoprotein-C and high-density lipoprotein-C levels, and leukocyte, neutrophil, lymphocyte, and platelet counts were also measured. Results were presented as mean?±?SD. The preoperative values were compared with the 3- and 12-month values. A p value?<?0.05 was considered statistically significant.

Results

BMI, weight, blood pressure, and waist circumference measurements were reduced at 3 and 12 months postoperatively compared with preoperative values (p?<?0.05). Among the inflammatory mediators, IgG, IgM, and Fbg were reduced to near-normal values, beginning in the early postoperative period (p?<?0.05). There was no significant reduction parallel to weight loss with respect to CRP, C3, C4, and IgA values at 3 months postoperatively (p?>?0.05). However, the 12-month values of these parameters were significantly reduced (p?<?0.05).

Conclusions

Morbid obesity leads to significant changes in the levels of inflammation mediators. While there is a significant reduction in some of these mediators accompanying slight weight loss in the early period following an LAGB procedure, significant changes occur in other mediators in the late period when there is a larger amount of weight loss.     

The effects of biotin supplementation on serum and liver tissue biotinidase enzyme activity and alopecia in rats which were administrated to valproic acid

Valproic acid (VPA) is a widely used and well-tolerable antiepileptic drug in epileptic patients. However, VPA has many side effects dose-dependent or non-dose-dependent. It is reported that VPA treatment may lead to biotin deficiency and low serum and liver tissue biotinidase enzyme activity (BEA). Major clinical manifestations in biotin deficiency are seborrheic dermatitis, dry skin, fine and brittle hair, and alopecia. We aimed to investigate the effects of biotin supplementation on serum and liver tissue BEA and alopecia during VPA therapy. Rats were randomly divided into 4 groups, each consisted of 15 rats (VPA-B1, VPA-B2, VPA, and control). Except the control group, all groups were administrated VPA dose of 600 mg/kg/d per oral (PO) for 60 days with 12h intervals two divided doses. VPA-B1 was administrated biotin dose of 6 mg/kg/d and VPA-B2 was administrated biotin dose of 0.6 mg/kg/d. In the third week of the study, we determined alopecia in the study groups. Alopecia was seen in the subjects of 13.3% of VPA-B1 (n=2), 13.3% of VPA-B2 (n=2), and 40% of VPA (n=6). But statistical significant effect on alopecia by biotin supplementation was not able to be determined between the study groups. In the control group, alopecia was not observed. The ratios of alopecia in the study groups were statistically higher than the control group (p=0.028). Itchiness was more obvious in the study groups compared with the control group. Serum biotin levels of the biotin supplemented groups (VPA-B1 and VPA-B2) were higher than the other groups (VPA and control group). Serum biotin levels of the VPA group were lower than the control group. There were significant decreases in the levels of serum and liver tissue BEA of the study groups compared with the control group. In conclusion we showed that VPA usage reduced the serum and liver tissue BEA and impaired the biotin utilization by affecting the liver. Partial biotinidase deficiency may lead to alopecia. It might be prevented by biotin supplementation in the patients receiving VPA therapy. We considered that further studies are necessary to find out the effective and safe biotin dose.     

The change in plasma GABA,glutamine and glutamate levels in fluoxetine- or S-citalopram-treated female patients with major depression

Objective  The aim of this study was to investigate the relationship between plasma glutamate, glutamine and γ-aminobutyric acid (GABA) levels in female patients with major depression treated with S-citalopram or fluoxetine. Methods  The patients were assigned into S-citalopram (10 mg/day) or fluoxetine (20 mg/day) groups (n = 15 per group). The Hamilton and Beck Depression Inventory Scales were performed on all study participants, and blood samples were collected. The same procedures were repeated 10 days following the onset of therapy. Fifteen female healthy volunteers were also included in the study for the evaluation of normal plasma levels. Results  The plasma GABA levels of the healthy volunteers were higher whereas those for glutamate and glutamine were lower than the day zero samples of the patients. An increase in plasma GABA levels and a decrease in glutamate and glutamine levels were observed on the 10th day of treatment. No difference was detected between the drug treatments. Conclusion  Our findings may suggest that GABA, glutamate and glutamine play a role in depression and that plasma GABA may be used as a biomarker for treatment control.     

Rare clinical presentation of nonobstructive hypertrophic cardiomyopathy: apical aneurysm with thrombus

Hypertrophic cardiomyopathy patients rarely have left ventricular apical aneurysms without coronary artery disease and the pathophysiological processes responsible for apical wall thinning and aneurysm formation are not known exactly today. Here we present a rare nonobstructive hypertrophic cardiomyopathy case with an apical thrombotic aneurysm.
