Status of Serum Calcium, Phosphate and Intact Parathyroid Hormone in Predialysis Chronic Kidney Disease Patients of Stage-3 to Stage-5 Compared To KDOQI Guideline.

The chronic kidney disease (CKD) is associated with a variety of bone disorders and disorders of calcium and phosphorus metabolism. Bone disease associated with chronic kidney disease having higher rate of CKD progression and increased risk of death. To see the status of serum calcium, phosphate and intact parathyroid hormone in pre-dialysis CKD (stage- 3 to 5) patients. This was a across sectional study done in outpatient department of Nephrology of National Institute of Kidney Diseases and Urology, Dhaka, between 1st June 2012 to 31st May 2013. The patients of CKD stage 3, 4 and 5 yet not on dialysis attending out patients department of Nephrology, NIKDU by using MDRD-4 equation according to K/DOQI guidelines and reviewing previous medical records and investigation reports were enrolled in this study. There after serum calcium (corrected for serum albumin), phosphate and iPTH levels were measured and compared with the recommended target ranges in K/DOQI guideline. The number of patients with serum levels according to K/DOQI guidelines for different stages CKD(3,4,5) were as follows: serum calcium: 56.6, 58.5 and 76.7; serum phosphate: 55.2, 58.5 and 56.7; iPTH 37.9, 12.2 and 36.7 and Ca x P product 100.0, 97.6 and 86.7, respectively. The percentages of patients (who received drug) with serum calcium levels within according to K/DOQI guidelines for stages 3, 4 and 5 were as follows: serum calcium: 63.2%, 64.7% and 83.3%; respectively, serum phosphate: 63.2%, 61.8% and 66.7%; respectively, iPTH 42.1%, 14.7% and 4.7% and Ca x P product 100.0%, 100.0% and 87.5%, respectively. On the other hand patients who didn't receive drug the percentages of patients with serum calcium levels according to K/DOQI guidelines for CKD stages 3, 4 and 5 were as follows: serum calcium: 50.0%, 28.6% and 50.0%; respectively, serum phosphate: 40.0%, 42.9% and 16.7%; respectively, iPTH 30.0%, 14.7% and 16.7% and Ca x P product 100.0%, 85.7% and 83.3%, respectively. The patients achieving the four recommendations of K/DOQI guidelines was 4(13.8%) in stage-3, 3(7.3%) in stage-4 and 5(16.7%) in stage-5. More than half of the pre-dialysis patients of CKD were within target range of serum calcium and phosphate recommended in K/DOQI guideline and this proportion was more in those who were taking both phosphate binder and Vit-D. Ca x P was within target range in almost all patients so it may not be an important parameter for therapeutic decision making. However majority of the patients were out of target range of iPTH even though having normal serum calcium and phosphate level. So emphasis should be given in monitoring of iPTH level in early stages of CKD.

Surgical treatment of hydatid cyst of liver.

Results of surgery in 52 cases of hepatic hydatid disease are described. Ultrasound examination proved to be the most useful and accurate diagnostic tool. All the patients were treated by enucleation of cyst and closed suction drainage of the cavity lined by pericyst. Mebendazole was given routinely pre-operatively for 15-30 days and postoperatively for 3 months. This mode of treatment had greatly reduced the morbidity and mortality as compared to conventional hydatid cyst surgery.

Amoebic liver abscess. Review of 220 cases.

Two hundred and twenty cases of amoebic liver abscess were seen between 1981-1986. The majority were young or middle aged males belonging to the lower socio-economic group and 85% gave a history of drinking toddy (fermented palm juice). The highest incidence of the disease occurred during the peak toddy season (April to July). Toddy drinkers become susceptible perhaps because of the large dose of Entamoeba histolytica and bacteria ingested with the drink, associated malnutrition, poor hygiene, hepatic dysfunction and possible suppression of amoebistatic substance. Useful investigations consisted of skiagram and ultrasonography, the later being sometimes used to guide the aspiration needle to abscesses situated at unconventional sites. Over 88 per cent responded well to conservative treatment with aspiration(s). Laparotomy was required in slightly over 10% of cases and in these the mortality was 12% as compared to 2% with conservative treatment. Although a large amount of liver tissue appears to be destroyed, the residual liver damage is clinically, biochemically, macroscopically and microscopically minimal.

Closed pyloroduodenal digital dilatation as a complementary drainage procedure to truncal vagotomy.

Out of a total of 300 consecutive cases of duodenal ulcer undergoing surgery, 51 patients were treated by truncal vagotomy and a closed pyloroduodenal digital dilatation. A peroperative assessment of the pyloroduodenal canal was carried out, and in patients with a mobile, supple duodenum showing minimal scarring a standard drainage procedure was not considered necessary. In these patients it was possible to perform a closed pyloroduodenal digital dilatation using the two thumbs to achieve an effective dilatation of 20-30 mm. Post-operative clinical evaluation (Modified Visick grading) and "special" barium meal revealed 86% of patients in Grade I and II at the end of two years (maximum follow-up 3.5 yrs.), with no evidence of lasting gastric stasis. The method is easy, safe and simple. It maintains the anatomical and physiological integrity of the pyloroduodenal ring thereby obviating the hazards of an "incontinent" stomach. Its main limitation appears to be its restricted selectivity and in the present series it could be carried out in about 17% of cases.
