Treatment of dental, craniofacial and orthopedic defects with bone graft substitutes has shown promising result achieving almost complete bone regeneration depending on product resorption similar to human bone's physicochemical and crystallographic characteristics. Among these, non-ceramic and ceramic hydroxyapatite being the main inorganic salt of bone is the most studied calcium phosphate material in clinical practices ever since 1970s and non-ceramic since 1985. Its "chemical similarity" with the mineralized phase of biologic bone makes it unique. ⋯ The need for bone graft material keeps on increasing with increased age of the population and the increased conditions of trauma. Recent advances in genetic engineering and doping techniques have made it possible to use non-ceramic hydroxyapatite in larger non-ceramic crystals and cluster forms as a successful bone graft substitute to treat various types of bone defects. In this paper we have mentioned some recently studied properties of hydroxyapatite and its various uses through a brief review of the literatures available to date.

Cervical cancer recurrence in episiotomy scars after vaginal deliveries is a rather rare event. ⋯ Clinicians should be aware about the importance of carefully examining not only the cervix at the time of labor, but also the episiotomy scar in women following a pregnancy complicated by cervical cancer.

This study is a citation analysis of the top 100 most cited papers in adult cardiac surgery. Bibliometric analyses are viewed as a proxy marker of a paper's influence and, therefore, an analysis of the most influential papers published in recent decades. ⋯ Despite the potential flaws with bibliometric analysis, and its application to cardiac surgery, there is inherent merit in an analysis of this type.

In recent years hypertonic saline has attracted increasing interest in the treatment of traumatic intracranial hypertension, and has a number of documented and theoretical advantages over other hyperosmolar agents. To date, no consensus has been achieved on the safest and most effective HTS concentration for administration. ⋯ No associated harmful biochemical or haematological abnormalities were noted. In conclusion, highly concentrated 30 % HTS appears to be both effective and safe in the management of refractory intracranial hypertension.

Methods of teaching and assessment in medical schools have transformed over the recent past. Accreditation of medical schools through national licensing bodies and removal of bias at examinations is the norm. This review is intended to inform senior doctors who are peripherally involved in training at speciality or general professional level. ⋯ Examining the performance of examiners as well as that of students is a necessary part of good examination practice. The World Federation for Medical Education with the World Health Organisation has developed nine standards with two categories of basic and quality for the accreditation of medical education.
