Comparison of Malnutrition Prevalence Between Haemodialysis and Continuous Ambulatory Peritoneal Dialysis Patients: A Cross-sectional Study

Introduction: Introduction: Malnutrition is a serious unresolved nutritional problem amongst dialysis patients associated with increased mortality and morbidity and prevalence differs according to dialysis modalities. This study compared protein- energy malnutrition (PEM) prevalence in haemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD) patients. Methods: A total of 155 HD and 90 CAPD patients were enrolled. PEM prevalence was determined using body mass mdex (BMI), serum albumin, Dialysis Malnutrition Score (DM5) and dietary intake. Results: CAPD patients had significantly higher BMI (24.1 � 4.8 kg/m2 vs. 22.7 � 4.8 kg/m2 p=O.024) and mid-arm muscle area (32.1 � 12.4 cm2 vs. 29.5 � 15.9 cm2 p=O.044) than HD patients. They also had significantly lower serum albumin (31 � 5 g/L vs. 35 � 6 g/L; p5 years were independent risk factors of PEM hi dialysis patients. Conclusion: Periodic nutritional assessments, education and dietary counseling should be emphasised in these patients as a preventive measure of PEM.

A re-evaluation of plasma sialic acid determination using the periodate resorcinol method versus the enzymatic method.

The concentration of plasma sialic acid was estimated using the modified chemical method and the more sensitive enzymatic method in 20 subjects with impaired glucose tolerance and 20 control subjects. The mean sialic acid concentration values of the control subjects and subjects with impaired glucose tolerance using the enzymatic method were 1.747 +/- 0.047 and 2.583 +/- 0.070 mmole/l and 1.753 +/- 0.067 and 2.591 +/- 1.02 mmole/l for the chemical method. The intra-assay coefficient of variation for the control subjects and for the subjects with impaired glucose tolerance were 1.963% and 1.583%, respectively, for the enzymatic assay and 2.728% and 2.431%, respectively, for the chemical assay. The inter-assay coefficient of variation for the control subjects and for the subjects with impaired glucose tolerance were 2.686% and 2.723% for the enzymatic assay, and 3.819% and 3.95% for the chemical assay. Since the values do not differ significantly, the chemical assay is a cost effective method that can be used in large epidemiological studies.

Dentigerous cyst with an impacted canine in an unusual position-a case report.

A dentigerous cyst is a type of an odontogenic cyst associated with the crown of an impacted, embedded or unerupted tooth. In this article, we report a case of dentigerous cyst with an impacted canine in an unusual position which was surgically removed.
