The term craniosynostosis denotes the pathological partial or complete absence of one or more cranial sutures which manifests as abnormal skull growth. Although it is often referred to as premature fusion this is misleading as only the metopic suture fuses in the normal physiological state. The remaining sutures change and mature in macroscopic and microscopic form during growth but remain present. This chapter discusses the assessment of patients with craniosynostosis.
In some parts of the world, peritoneal dialysis is widely used for renal replacement in acute renal failure. In resource-rich countries, it has been supplanted in recent years by hemodialysis and, most recently, by hemofiltration and associated techniques. The relative efficacy of peritoneal dialysis and hemofiltration is not known.
The use of subcutaneous pulsatile luteinising hormone releasing hormone (LHRH) for induction of ovulation in patients with hypogonadotrophic hypogonadism is efficacious and safer compared to human menopausal gonadotrophin (hMG) because of the lower risk of ovarian hyperstimulation and multiple pregnancy. In clomiphene citrate (CC) nonresponsive cases of polycystic ovarian disease (PCOD), the major advantage of pulsatile LHRH is that when ovulation occurs, it is usually uni-follicular. In cases of PCOD, we have found that if pulsatile LHRH alone fails to induce ovulation, addition of clomiphene citrate or a small dose of follicle stimulating hormone (FSH) will augment its action and allow, in the majority of cases, the threshold of stimulation to be reached that would be sufficient to induce ovulation but not produce clinical hyperstimulation or multiple pregnancy. LHRH analogues to desensitise the pituitary prior to ovarian stimulation with hMG have been recently used in in-vitro fertilisation (IVF). We have compared the use of the LHRH analogue, buserelin (Hoechst, UK) + hMG with clomiphene + hMG for ovarian stimulation in IVF in a number of prospective studies. In this review, the role of pituitary desensitisation in IVF is discussed in the light of our results. We have found that although the mean number of oocytes, the implantation rate and pregnancy rate per embryo transfer are higher in patients who receive buserelin + hMG, the differences are not statistically significant. The length of time taken to achieve pituitary desensitisation is increased in patients who have PCOD or who form ovarian cysts in response to the administration of buserelin.(ABSTRACT TRUNCATED AT 250 WORDS)

Artemisinin-based combination treatments have been the mainstay of treatment for falciparum malaria in Southeast Asia for more than 10 years and are now increasingly recommended as first-line treatment throughout the rest of the world.A large multicentre randomised trial conducted in East Asia has shown a 35% reduction in mortality from severe malaria following treatment with parenteral artesunate compared with quinine. There is increasing evidence that artemisinin-based combination treatments are safe and rapidly effective. Artemether-lumefantrine (six doses) has been shown to be very effective in large trials reported from Uganda and Tanzania. A once daily three-dose treatment of dihydroartemisinin piperaquine, a newer fixed combination, was a highly efficacious and well tolerated treatment for multi-drug resistant falciparum malaria in Southeast Asia.Early diagnosis and treatment of uncomplicated malaria with effective drugs remains a priority as part of a comprehensive malaria control strategy. Artemisinin-based combination treatments have consistently been shown to be highly effective and safe. The challenge is to make them accessible in tropical countries.
