White Phosphorus injure, management
The management of white phosphorus burns.
Phosphorus burns are a rarely encountered chemical burn, typically occurring in battle, industrial accidents, or from fireworks. Death may result even with minimal burn areas. Early recognition of affected areas and adequate resuscitation is crucial. Amongst our 2765 admissions between 1984 and 1998, 326 patients had chemical burns. Seven admissions were the result of phosphorus burns
. Our treatment protocol comprises 1% copper sulfate solution for neutralization and identification of phosphorus particles, copious normal saline irrigation, keeping wounds moist with saline-soaked thick pads even during transportation, prompt debridement of affected areas, porcine skin coverage or skin grafts for acute wound management, as well as intensive monitoring of electrolytes and cardiac function in our burns center. Intravenous calcium gluconate is mandatory for correction of hypocalcemia. Of the seven, one patient died from inhalation injury and the others were scheduled for sequential surgical procedures for functional and cosmetic recovery. Cooling affected areas with tap water or normal saline, prompt removal of phosphorus particles with mechanical debridement, intensive monitoring, and maintenance of electrolyte balance are critical steps in initial management. Fluid resuscitation can be adjusted according to urine output. Early excision and skin autografts summarize our phosphorus burn treatment protocol.
Severe thiamine deficiency causes, beriberi, which is a disorder typically associated with a diet consisting largely of polished rice. It may also occur when refined wheat flour forms a major part of the diet and among alcoholics and food faddists. Thiamine deficiency can develop within 2-3 months of inadequate consumption; it is characterized either by cardiac involvement with oedema or by peripheral neuropathy, with intermediate forms between these two extremes also occurring. Left untreated, thiamine deficiency leads to disability and death. In the past decade, several refugee populations that were wholly dependent on food aid have developed thiamine deficiency.
This document is intended primarily as a basis for ensuring adequate thiamine intake among populations in emergency settings. It reviews strategies for preventing thiamine deficiency among refugees and analyses factors influencing success and failure. Also included are a review of the literature on the epidemiology of thiamine deficiency and its signs and symptoms; thiamine’s properties and functions and the recommended daily allowance; and a discussion of food sources of this vitamin and its stability.
Thiamine deficiency and its prevention and control in major emergencies is the second in an occasional WHO series on the prevention and control of micronutrient deficiencies during emergencies. Reviews concerning scurvy and pellagra are also available.

A comprehensive scientific overview of Garcinia cambogia.
The fruit rind of Garcinia gummi-gutta, commonly known as Garcinia cambogia (syn.), is extensively used traditionally as a flavourant in fish curries due to its sharp sour taste. Additional ethnobotanical uses include its use as a digestive and a traditional remedy to treat bowel complaints, intestinal parasites and rheumatism. This small fruit, reminiscent of a pumpkin in appearance, is currently most popularly used and widely advertised as a weight-loss supplement. Studies have shown that the extracts as well as (-)-hydroxycitric acid (HCA), a main organic acid component of the fruit rind, exhibited anti-obesity activity including reduced food intake and body fat gain by regulating the serotonin levels related to satiety, increased fat oxidation and decreased de novo lipogenesis. HCA is a potent inhibitor of adenosine triphosphate-citrate lyase, a catalyst for the conversion process of citrate to acetyl-coenzyme A, which plays a key role in fatty acid, cholesterol and triglycerides syntheses. The crude extract or constituents from the plant also exerted hypolipidaemic, antidiabetic, anti-inflammatory, anticancer, anthelmintic, anticholinesterase and hepatoprotective activities in in vitro and in vivo models. Phytochemical studies of various plant parts revealed the presence of mainly xanthones (e.g. carbogiol) and benzophenones (e.g. garcinol) together with organic acids (e.g. HCA) and amino acids (e.g. gamma aminobutyric acid). Currently, a large number of G. cambogia/HCA dietary supplements for weight management are being sold although the possible toxicity associated with the regular use of these supplements has raised concerns. In most cases, complaints have been related to multicomponent formulations and at this stage G. cambogia has not been confirmed as the potentially toxic culprit. This review presents a scientific overview of G. cambogia with reference to relevant botanical aspects, ethnobotanical uses, phytochemistry and biological activity as well as toxicity.

WHO to convene an International Health Regulations Emergency Committee on Zika virus and observed increase in neurological disorders and neonatal malformations
28 January 2016
WHO Director-General, Margaret Chan, will convene an International Health Regulations Emergency Committee on Zika virus and observed increase in neurological disorders and neonatal malformations.
The Committee will meet on Monday 1 February in Geneva to ascertain whether the outbreak constitutes a Public Health Emergency of International Concern.
Decisions concerning the Committee’s membership and advice will be made public on WHO’s website.
Outbreak in the Americas
In May 2015, Brazil reported its first case of Zika virus disease. Since then, the disease has spread within Brazil and to 22 other countries and territories in the region.
Arrival of the virus in some countries of the Americas, notably Brazil, has been associated with a steep increase in the birth of babies with abnormally small heads and in cases of Guillain-Barré syndrome, a poorly understood condition in which the immune system attacks the nervous system, sometimes resulting in paralysis.
A causal relationship between Zika virus infection and birth defects and neurological syndromes has not been established, but is strongly suspected.
WHO’s Regional Office for the Americas (PAHO) has been working closely with affected countries since May 2015. PAHO has mobilized staff and members of the Global Outbreak and Response Network (GOARN) to assist ministries of health in strengthening their abilities to detect the arrival and circulation of Zika virus through laboratory testing and rapid reporting. The aim has been to ensure accurate clinical diagnosis and treatment for patients, to track the spread of the virus and the mosquito that carries it, and to promote prevention, especially through mosquito control.
The Organization is supporting the scaling up and strengthening of surveillance systems in countries that have reported cases of Zika and of microcephaly and other neurological conditions that may be associated with the virus. Surveillance is also being heightened in countries to which the virus may spread. In the coming weeks, the Organization will convene experts to address critical gaps in scientific knowledge about the virus and its potential effects on fetuses, children and adults.
WHO will also prioritize the development of vaccines and new tools to control mosquito populations, as well as improving diagnostic tests.
