PATTERN OF RENAL DISEASES AMONG CHILDREN ATTENDING PAEDIATRIC NEPHROLOGY CLINIC, FEDERAL TEACHING HOSPITAL, GOMBE.

Introduction: Children present with a spectrum of renal diseases depending on age, sex, and geographic location among other factors. With the absence of a paediatric renal registry in Nigeria, this will provide part of the regional data necessary for the Nigerian renal registry. Methodology: A retrospective study where cases of renal diseases that presented in a nephrology clinic over a 2-year period were retrieved from the nurses' and doctors' records and analysed. Results: A total of 147 children were reviewed, male and female were 101 and 46 respectively with M: F being 2.2: 1. Mean age was 9.59 ± 4.58 years, age distribution were <5 years (23.0; 15.6%), 5-9 years (52; 35.4%) and ≥ 10 years (72.0; 49.0%). The majority (77.0; 52.4%) had low socioeconomic status. Majority (145; 98.6%) were acquired renal diseases while ectopic kidney (2.0; 1.4%) was the only CAKUT. Acute glomerulonephritis (49; 33.3%), urinary tract infections (37; 25.2%) and nephrotic syndrome (30.0; 20.4%) were the major acquired renal diseases. Acute kidney injury (AKI) and chronic kidney disease (CKD) were seen in 9 (6.1%) and 13 (8.8%) respectively. Urolithiasis, sickle cell nephropathy, and primary enuresis were seen in 5(3.4%) and 1 (0.7%) respectively. The mean age of children with CAKUT and acquired renal diseases were13.00 ±1.41 and 9.54±4.59 years (P=0.290) while that of AKI and CKD were 10.89±5.21 and 14.15±3.24 years respectively (P= 0.084). Conclusion: Childhood renal diseases increase with age and are more common among adolescents, especially the chronic forms. Regular screening and aggressive treatment are recommended in adolescents.

Prevalence and 30-day all-cause mortality of carbapenem-and colistin-resistant bacteraemia caused by Acinetobacter baumannii, Pseudomonas aeruginosa, and Klebsiella pneumoniae: Description of a decade-long trend.

BACKGROUND: Bacteraemia due to carbapenem-resistant gram-negative bacteria is challenging. This study examined the burden of carbapenem and colistin resistance in Klebsiella pneumoniae, Pseudomonas aeruginosa, and Acinetobacter baumannii bacteraemia in Oman. METHODS: Adult patients admitted to Sultan Qaboos University Hospital between January 1, 2007 and December 31, 2016 with positive blood cultures for P. aeruginosa, A. baumannii, or K. pneumoniae were identified. Rates of carbapenem resistance, trends in prevalence, and 30-day all-cause mortality were examined. RESULTS: Two hundred and twenty-seven (29.8%) of 761 bacteraemia cases due to these three isolates were carbapenem-resistant, with 87.2% being healthcare-associated. A. baumannii caused 52% of all carbapenem-resistant bacteraemia, K. pneumoniae caused 30%, and P. aeruginosa caused 18%. Rates of carbapenem resistance in P. aeruginosa, A. baumannii, and K. pneumoniae bacteraemia increased from 20%, 67%, and 0%, respectively, in 2007 to 25%, 86%, and 35%, respectively, in 2016. Seventeen (7.9%) carbapenem-resistant bacteraemia cases were also colistin-resistant. Thirty-day all-cause mortality was 62% in patients with carbapenem-resistant bacteraemia and 22% in patients with carbapenem-sensitive bacteraemia. CONCLUSIONS: The prevalence of carbapenem-resistant K. pneumoniae, A. baumannii, and P. aeruginosa bacteraemia is increasing alarmingly in Oman, with a large proportion of K. pneumoniae and P. aeruginosa demonstrating additional resistance to colistin. Patients with carbapenem-resistant bacteraemia had higher 30-day all-cause mortality.

Torus mandibularis bone chips combined with platelet rich plasma gel for treatment of intrabony osseous defects: clinical and radiographic evaluation.

The use of platelet rich plasma (PRP) gel in combination with torus mandibularis offers a potentially useful treatment for periodontal osseous defects. Whether this combination enhances the outcome of periodontal regenerative therapy is not known. This study compared the effectiveness of torus mandibularis bone chips alone and when combined with autogenous PRP gel in treating periodontal osseous defects. 24 sites from 12 patients were selected using a split mouth design and determined by a double-blind, randomized, controlled clinical trial. Both sites received a full-thickness mucoperiosteal flap; one intrabony defect was filled with torus mandibularis bone chips alone and the other with torus mandibularis bone chips mixed with PRP gel. There was a 57% gain in the clinical attachment level and 60% reduction in the probing depth for torus mandibularis alone compared to 72% and 68% for sites treated with torus mandibularis and PRP gel (p ≤ 0.01). There was a statistically significant difference in the bone dentistry and the marginal bone loss at sites with PRP gel compared to those without gel (p ≤ 0.01). The use of mandibular tori as autogenous bone graft combined with PRP gel showed a significant improvement in the clinical outcome of periodontal therapy than mandibular tori alone.
