Vitiligo is an acquired pigmentry disorder of the skin and mucous membranes which manifests as white macules and patches due to selective loss of melanocytes. Etiological hypotheses of vitiligo include genetic, immunological, neurohormonal, cytotoxic, biochemical, oxidative stress and newer theories of melanocytorrhagy and decreased melanocytes survival. There are several types of vitiligo which are usually diagnosed clinically and by using a Wood's lamp; also vitiligo may be associated with autoimmune diseases, audiological and ophthalmological findings or it can be a part of polyendocrinopathy syndromes. Several interventions are available for the treatment for vitiligo to stop disease progression and/or to attain repigmentation or even depigmentation. In this article, we will present an overall view of current standing of vitiligo research work especially in the etiological factors most notably the genetic components, also, types and associations and various and newer treatment modalities.

Background: The recent events in Iraq following the 2003 war render Iraq as a country with a high level of all types of violence. Exposure to violence, as a witness or a victim, is related to a number of longer term emotional, behavioral and social problems. Objectives: To investigate the impact of witnessing and experiencing community violence and tragedy as a factor contributing to mental health disorders among Iraqi women in the city of Mosul. Methods: A population-based cross-sectional study of 500 women were selected by a multi-stage random sampling technique. Four catchment areas of primary health centers of Mosul city were selected. Community violence with nine commonly associated social, economic, emotional, physical and mental health symptoms were recorded by questionnaire. Results: The study revealed that all the participating women had a history of exposure to at least one type of community violence within the last twelve months. A mainstream consequence of exposure to community violence was transportation difficulties, loss of husband's job, and family displacement. More than half of the women were classified as having severe emotional disturbances that may evolve to mental health problems in future. Conclusion: Women are bearing the consequences of the violence in Iraq. National commitment and action needs to be taken to curb the violence which is hugely affecting the people of Iraq. Treatment programs targeted at promoting emotional resilience may be effective at preventing mental health problems.

Extra pontine myelinolysis (EPM) is a form of osmotic demyelination syndrome, characterized by the presence of signal alterations in varied sites in the brain other than the pons. When caudate and putamen are involved, it results in a constellation of extra pyramidal signs and symptoms resembling parkinsonism. Here we report a case of this unique syndrome presenting with features of parkinsonism which was successfully treated with dopaminergic drugs.

In Yemen, the prevalence of sickle cell trait and β-thalassemia trait are high. The aim of this premarital program is to identify sickle cell and thalassemia carrier couples in Yemen before completing marriages proposal, in order to prevent affected birth. This can be achieved by applying a low-cost premarital screening program using simple blood tests compatible with the limited health resources of the country. If microcytosis or positive sickle cell is found in both or one partner has microcytosis and the other has positive sickle cell, so their children at high risk of having sickle cell or/and thalassemia diseases. Carrier couples will be referred to genetic counseling. The outcomes of this preventive program are predicted to decrease the incidence of affected birth and reduce the health burden of these disorders. The success of this program also requires governmental, educational and religious supports.

Congenital pulmonary agenesis is a rare condition which poses diagnostic difficulties. More than 50% of these patients die before the first five years of life. Few patients may remain asymptomatic throughout their life. We report a case of a two month old male infant with right pulmonary agenesis who presented with severe respiratory distress in whom a diagnosis was made following computed tomography of the chest.

This study reports the case of a 61-year-old man with right upper quadrant pain who underwent abdominal computed tomography examination. A solid lesion originating from the biliary tract was detected on the images. While evaluating the vascular structures, the splenic artery was seen to directly originate from the abdominal aorta. Retro-aortic left renal vein was also seen on computerised tomography. Splenic artery originating from the abdominal aorta is a rare variation. The retro-aortic left renal vein is a malformation characterized by the presence of a vessel that drains the left renal blood up to the inferior vena cava crossing behind the aortic artery. Such anatomical variations are important for surgeons to be aware of.

Rupture of an aneurysm is a rare complication although it is considered a common cause of death. Some of these patients present with the classic triad of symptoms such as abdominal pain, pulsatile abdominal mass and shock. Most symptoms are misleading and will only present as vague abdominal pain. Here we describe one such patient with an unusual presentation of a misleading abdominal mass which was eventually diagnosed as a ruptured abdominal aortic aneurysm after an emergency MRI.

Background: Accidental injuries are the most common cause of death in children over the age of one. Every year, millions of children are permanently disabled or disfigured because of accidents. Objective: To assess the level of knowledge of women with respect to children's domestic accidents, and to determine its association with some demographic factors. Method: This cross-sectional study was conducted in both sides of Baghdad City during the period from April through to August 2013. The targeted population were women attending the primary health care centers (PHCCs). A random sample of 20 PHCCs was taken through a stratified random sampling technique by dividing Baghdad City into its two main parts Karkh and Russafa. Ten centers were then chosen from each sector by a simple random sampling technique. A well-structured questionnaire was developed that constituted of questions on four main types of accidents involving children (poisoning by chemicals and detergents, electric shock, injuries from sharp instruments in the kitchen, and burns). Results: The total number of women enrolled in this study was 1032 aged from 15–50 years. The results revealed that only 9.2% of the mothers acquired a good level of knowledge in prevention of injuries from chemicals and detergents, and more than 90% were found to have poor knowledge. The same was found regarding knowledge about preventing electrical accidents caused by power sockets and electrical appliances where only 10.2% of the mothers were found to have a good level of knowledge. The results were not much better regarding accidents caused by fire, only 11.6% of the mothers scored well. With respect to dealing with accidents caused by sharp instruments in the kitchen, only 6.3% of the mothers obtained a score that indicated a good level of knowledge. Older mothers were statistically found to have a better level of knowledge than younger mothers. Higher educated mothers' were statistically associated with a lower level of knowledge in accident prevention. Mothers with more children and those whose children had previously been involved in an accident were found to have a better level of knowledge. Conclusion: It can be concluded from this study that women in Baghdad are poorly educated about how to protect their children against domestic accidents.

Background: Inborn errors of metabolism (IEM) are mostly transmitted as autosomal recessive disorders and are therefore more frequent in countries with high consanguinity rates such as in the Arab world. Objective: To study the socio-demographic characteristics and the clinical presentation of IEM in Libyan children and to shed light on our experience in dealing with these disorders. Methods: This is a descriptive case series hospital-based study of 107 children attending the Metabolic Unit at El-Khadra Teaching Hospital (MUKH) in Tripoli, Libya. The study took place between January 2001 and December 2012. Information was collected from caregivers and from all available hospital records on the following variables: age, sex, birth order, place of residence, age at onset, presenting complaints and family history of the same illness. Results: During the 12-year study period, there were 55,422 live births at El-Khadra Teaching Hospital and 107 children were diagnosed with 46 different metabolic disorders. A significantly high consanguinity rate was observed (86.9%) among parents of the affected children. Family history of previous affected children was noted in 63.5% of cases. Male to female ratio was 1.18:1. The most frequent IEM cases were amino acids disorders (25%), carbohydrate disorders (14.9%), lysosomal storage diseases (14%), organic aciduria and energy metabolic defects (9.3% each). The main clinical presentations were jaundice, hepatomegaly and seizures. Most children presented between one and six months of age (43.4%); whereas the median age at diagnosis was eight months. Thirty-eight children (35.5%) were born at El-Khadra Hospital with IEM giving a birth prevalence of 1:1458 live births, (1:6158 for aminoaciduria and 1:6927 for carbohydrate disorders). Conclusion: IEM disorders are common in Libya. Efforts to enhance awareness among pediatricians and primary healthcare providers should be supported and encouraged as many diseases are still undiagnosed. It is very important to consider IEM among all children when they present any worrying or suspicious symptoms or signs which do not respond to conventional treatment. Although our findings are preliminary, and probably the first to be conducted in Libya, they suggest ideas for decision makers to plan services including newborn screening programs and country-wide research of IEM diseases.
