Objectives To determine the effect of changing dialysate volume on urea and glucoseequilibration curves and to determine, if dialysate volume is prescribed on the basis of body surface area, whether equilibration curves will be consistent in patients of different sizes and ages. Design A prospective study wherein children with acute or chronic renal failure had peritoneal equilibration studies done with dwell volumes of 30 mL/kg, 40 mL/kg, and 1200 mL/m2. Patient Population Twenty-two children: 7 under 3 years of age; 8 between 3 and 10 years of age; 7 older than 10 years of age. Statistics Student's t-test. Results Urea and glucose equilibrated rapidly at dwell volumes of 30 mL/kg, slower at dwell volumes of 40 mL/kg, and slowest at dwell volumes of 1200 mL/m2. Equilibration curves were similar in children of different ages when dialysate volumes of 1200 mL/m2 were infused. Conclusion Dialysate volumes of 1200 mL/m2 should be used when equilibration studies are being done to compare individuals of different ages and sizes.

ABSTRACT Context: Presurgical nasoalveolar moulding (PNAM) is a non-surgical method of reshaping the cleft lip, alveolus, palate and the nose to minimize the severity of the cleft deformity, before primary cheiloplastyand palatoplasty. In this context, PNAM proves to be an invaluable asset in the management of unilateral cleft lip and palate. Aims: The study was conducted to evaluate the effi cacy of PNAM in the management of unilateral cleft lip and palate with the following objectives: (1) To assess and compare the degree of reduction in the size of cleft palate and alveolus (pre-PNAM and post-PNAM). (2) To evaluate and compare the improvement in columellar length and correction of columellar deviation (pre-PNAM and post-PNAM). (3) To assess the changes in the position of the alar base and the alar cartilages. Settings and Design: Prospective study. Subjects and Methods: A prospective study consisting of, which included 20 patients with complete unilateral cleft lip and palate was conducted. The age at the start of PNAM treatment of the infants ranged from 2 to 44 days of age reporting to our institute between December 2011 and August 2013. All the patients underwent PNAM therapy before primary cheiloplasty at 6 months of age; clinical parameters were assessed pre- and post-therapy using photographs and dental study models of the maxilla. Statistical Analysis Used: Student's t-test for paired comparisons. Results: Results of the study showed a promising reduction in the cleft size before the surgery, signifi cant improvement in nasal symmetry, including the columellar length on the cleft side. Conclusions: PNAM is a valuable adjunct to our surgical armamentarium in dealing with the challenges of primary closure of unilateral cleft lip and palate thereby enhancing the overall surgical outcome. The advantages of this method include the simplicity of the procedure and improving the quality of surgical repair, particularly in obtaining tension free muscle closure in unilateral clefts.

AbstractA prospective study for the treatment of quinsy was undertaken between January 1989 and September 1991. This was to determine whether abscess tonsillectomy reduces inpatient stay without increasing operative risk compared to incision and drainage combined with interval tonsillectomy. Fifty-three patients were entered into the study. Twenty-one had abscess tonsillectomy and 32 had incision and drainage. This study showed that there is a 95 per cent probability that abscess tonsillectomy reduces hospital stay by between 2.04 and 4.84 (Student's t test t = 5.01; df = 31, p<0.001) days compared to incision and drainage followed by interval tonsillectomy. This is a significant saving in time and resources. Abscess tonsillectomy reduces patients lost to follow-up, avoids the social inconvenience of a second admission, effectively relieves symptoms, treats a contralateral abscess and is the only method of treating children with a quinsy. We recommend abscess tonsillectomy should be performed for quinsy where expertise and facilities are available.

A Prospective Study

SummaryA prospective study was made of 17 dogs with ununited anconeal process treated by osteotomy of the proximal ulna. The effect of the surgery on lameness was evaluated subjectively and the elbows were assessed radiographically for evidence of anconeal fusion and healing of the osteotomy. Whilst clinical outcome was generally good and complications infrequent, relatively few cases achieved anconeal fusion. These results do not compare well with the results of a previous study but this disparity may be due in part to differences in patient population and radiographic evaluation.Further work is required to establish how best to achieve predictable anconeal fusion.Proximal ulnar osteotomy was used to treat 17 dogs with ununited anconeal process. Clinical results were good but anconeal fusion was not achieved consistently. Further work is needed to determine how best to achieve predictable anconeal fusion.
