We studied gastric emptying of solid food, using a radionuclide technique, in 18 patients with chronic renal failure patients on hemodialysis: nine with nausea and vomiting or postprandial bloating and nine without. Both groups were compared with a group of normal subjects. Gastric emptying was consistent with a linear elimination in all groups. The regression coefficients of the symptomatic, asymptomatic, and control groups were -0.48 +/- 0.1%, -0.5 +/- 0.14%, and -0.58 +/- 0.15% min, respectively. These were not statistically different. Half-emptying times were 116.4 +/- 7.1 min, 97.8 +/- 13.7 min, and 98.7 +/- 5.6 min, respectively. These also were not statistically different. Values of percentage retention at 2.5 hours for the same groups were 31.6 +/- 5, 24.8 +/- 6.4, and 18.6 +/- 4.4, respectively, again with no statistical difference. Patients with chronic renal failure on hemodialysis, symptomatic or asymptomatic, have no obvious impairment of gastric emptying of solids.

A 67-year-old Chinese man presented to the emergency department with a history of abdominal bloating and shortness of breath. Initial electrocardiogram (ECG) showed atrial tachycardia (AT) with 2:1 atrioventricular (AV) conduction block. Six days after admission, he developed acute dyspnoea and confusion. Repeat ECG demonstrated a regular wide-complex tachycardia. Serum analysis revealed hyperkalaemia secondary to acute on chronic renal failure. Emergency treatment with intravenous calcium gluconate, 50% dextrose solution and short-acting insulin was instituted. The ECG promptly reverted to a narrow-complex AT with 2:1 AV conduction block. The diagnosis and treatment of AT are discussed.

Strongyloidiasis is a parasitic infection caused by Strongyloides stercoralis. The infection is usually mild or asymptomatic in normal immunocompetent individuals, but could be very severe or even fatal due to hyper infection in individuals who are immunosuppressed. This study aimed at determining the prevalence, risk factors and features of strongyloidiasis among diarrhea patients in Ibadan. This is a descriptive cross-sectional study of diarrhea patients from a teaching hospital, three major government hospitals and one mission hospital in Ibadan. Self administered questionnaire, clinical assessment and laboratory investigations were used to confirm health status and presence of S. stercoralis. Diagnosis was made by microscopic examination of stool in saline preparation and formol-ether concentration. One thousand and ninety patients, (562 (51.6%) males and 528 (48.4%) females) consisting 380 (34.9%) children and 710 (65.1%) adults who had diarrhea were studied. The prevalence rate for the parasite among diarrhea patients was 3.0%. While the risk factor for infection remains contact with contaminated soil, malnutrition, steroid therapy, HIV/AIDS, lymphomas, tuberculosis, and chronic renal failure. Others are maleness, institutionalism and alcoholism. Predominant clinical presentations are abdominal pain, chronic diarrhea, and bloating and weight loss, Strongyloides stercoralis should be considered in diarrhea patients who are either malnourished or immunosuppressed.

Intestinal parasites are an important cause of morbidity and mortality. Immunocompromised individuals may develop more severe forms of these infections. Taking into account the immunity impairment in patients suffering from chronic renal failure (CRF), we will determine the prevalence and associated symptoms of intestinal parasites in these patients. Controls without CRF were used for comparison. Stool samples were collected and processed for microscopic identification of parasites using the Formalin-ether concentration method. For Cryptosporidium diagnosis, the ELISA technique was used. One hundred and ten fecal samples from hemodialysis patients were analyzed, as well as 86 from a community group used as control group. A result of 51.6% of intestinal parasites was observed in hemodialysis patients and 61.6% in the control group. Cryptosporidium and Blastocystis were the most common infections in patients with CRF (26.4% and 24.5%, respectively). Blastocystis was the most common infection in the control group (41.9%), however no individual was found positive for Cryptosporidium. Among the CRF patients, 73.6% were symptomatic, 54.3% of these tested positive for at least one parasite, in contrast to 44.8% in asymptomatic patients (p = 0.38). The most common symptoms in this group were flatulence (36.4%), asthenia (30.0%) and weight loss (30.0%). In the control group, 91.9% were symptomatic, 60.8% of these tested positive for at least one parasite, in contrast to 71.4% in asymptomatic patients (p = 0.703). A significant difference between the two groups was observed with regard to symptoms, with bloating, postprandial fullness, and abdominal pain being more frequent in the control group than in the hemodialysis group (all p < 0.05). Comparing symptomatic with asymptomatic, there was no association in either group between symptoms or the prevalence of parasitic infection, nor with the type of parasite or with multiple parasitic infections. Patients with chronic renal failure are frequent targets for renal transplantation, which as well as the inherent immunological impairment of the disease itself, results in immunosuppression by medication. For this reason, carriers of intestinal parasites with pathogenic potential can develop serious clinical complications influencing the success of transplantation. This fact, coupled with the high prevalence of intestinal parasites and the dissociation between symptoms and infection in CRF patients, suggests that the stool test should be incorporated in routine propedeutics. Furthermore, preventive measures for the acquisition of parasites through the fecal-oral contamination route should be introduced.
