Peritoneal dialysis (PD) is a modality frequently preferred by patients for the management of their end-stage kidney disease; however, a major factor in its success is PD catheter placement and subsequent function. Optimal placement of PD catheters is generally accepted to be in the true pelvis, for this reason, many patients who are found to have a pelvic cavity obliterated by adhesions are often denied the opportunity to do PD. We report on four cases of an alternative advanced laparoscopic technique used in patients with inaccessible pelvic cavities, with three catheter placements in the intraperitoneal left iliac fossa/paracolic gutter and one case in the right paracolic gutter with subsequent good outcomes.

The most cost-effective method of prevention and control is through annual vaccination. However, unlike lumpy skin disease, annual vaccination against Rift Valley fever is not practiced by many farmers due to its sporadic occurrences and shortcoming of the existing vaccines.

We identified that Platyhelminthes, Rotifera, Annelida and Arthropoda are thriving at 1.4 km depths in palaeometeoric fissure water up to 12,300 yr old in South African mines.

The NCMP has been running for more than 30 years with several hundred active monitoring sites. Twenty-five sites on major rivers had sufficient continuous data for the estimation of salinity changes over a 25-year period and statistically significant upward or downward trends occurred at 17 of the 25 sites.

Significantly lower (P less than 0,001) oocyst numbers were obtained with the lasalocid diet as opposed to the controls receiving no lasalocid. No significant differences were found with regard to wool growth and related properties such as staple length, crimp, fibre thickness, clean yield and clean wool weight.

As no adverse effects were found it is concluded that further investigation is necessary to see whether the inclusion of low grade-treated roughages in the ration of horses would be of economic significance.
