Anticipated And Unanticipated Complications Of Severe Dengue In A Primigravida, Madiha Hashmi, Ghulam Zainab, Farah Khan

Department of Obstetrics & Gynaecology

As the incidence of dengue is rising among adults more cases of dengue fever are being reported during pregnancy. Physiological changes of pregnancy mask the pathognomonic features of severe dengue such as increased hematocrit, thrombocytopenia, and leukopenia and a high index of suspicion are required in endemic areas. Massive hemorrhage may complicate operative deliveries in unsuspected patients. World Health Organization recommends that all patients with severe dengue should be admitted to a hospital with access to intensive care facilities and blood transfusion. We present the successful management of hemorrhage and unanticipated complications of severe dengue in a young primigravida admitted …

Laparoscopic-Assisted Percutaneous Endoscopic Gastrostomy Tube Insertion In The Immediate Post-Partum Period For Head And Neck Cancer, Adil Aijaz Shah, Shabbir Akhtar, Nadeem Zuberi, Kamran Ali, Dania Aijaz Shah, Amir Hafeez Shariff

Department of Surgery

Abstract

Percutaneous endoscopic gastrostomy (PEG) tube placement serves as a well-tolerated and efficacious technique for long-term enteral access in patients with medical conditions precluding oral food intake. The nutritional optimisation of patients with oral cancer is mostly achieved via PEG tube placement. However, certain special situations, such as pregnancy and the immediatepost-partum period, may render the placement of PEG tubes to be a challenge. A 28-year-old pregnant female patient presented to us with the diagnosis of squamous cell carcinoma of the tongue during her third trimester. Definitive surgical resection was planned post-delivery along with simultaneous PEG tube placement. Immediately following …

Obstetrics and Gynaecology, East Africa

A comprehensive set of fully integrated anthropometric measures is needed to evaluate human growth from conception to infancy so that consistent judgments can be made about the appropriateness of fetal and infant growth. At present, there are 2 barriers to this strategy. First, descriptive reference charts, which are derived from local, unselected samples with inadequate methods and poor characterization of their putatively healthy populations, commonly are used rather than prescriptive standards. The use of prescriptive standards is justified by the extensive biologic, genetic, and epidemiologic evidence that skeletal growth is similar from conception to childhood across geographic populations, when health, …

Obstetrics and Gynaecology, East Africa

In 2015, as we review progress towards Millennium Development Goals (MDGs), despite significant progress in reduction of mortality, we still have unacceptably high numbers of maternal and newborn deaths globally. Efforts over the past decade to reduce adverse outcomes for pregnant women and newborns have been directed at increasing skilled birth attendance.1,2 This has resulted in higher rates of births in health facilities in all regions.3 The proportion of deliveries reportedly attended by skilled health personnel in developing countries rose from 56% in 1990 to 68% in 2012.4 With increasing utilisation of health services, a higher proportion of avoidable maternal …

Obstetrics and Gynaecology, East Africa

Child marriage is a human rights violation that robs a girl of her childhood, puts her health, growth, and development at risk, disrupts her education, limits her opportunities for empowerment and social development, and increases her risk of exposure to violence and abuse (for a review of the evidence on the negative effects of child marriage on girls and their children, see Parsons et al. 2015, in this issue). While child marriage is not mentioned specifically in the 1989 Convention on the Rights of the Child (CRC), the Convention does contain a provision requiring governments to abolish “traditional practices prejudicial …
