Lingual supplementation may not be required after articaine buccal infiltration anesthesia for lower molar extraction: a clinical comparative study / La suplementación lingual opcional después de la anestesia por infiltración bucal con articaína para la extracción de molares inferiores: un estudio clínico comparativo

Purpose: To investigate the anesthetic effectiveness of buccal infiltration (BI) versus buccal plus lingual infiltration (BI+LI) of 4% articaine for intra-alveolar extraction of erupted mandibular molar teeth. Material and Methods: Eighty patients were included in this prospective clinical study. They were randomly divided into 1 of 2 equal groups: the 1st group received BI of 4% articaine 1.8 ml and LI of 0.5 ml, while the 2nd group received 4% articaine 1.8 ml BI plus 0.5 ml LI of normal saline. Another 1.8 ml articaine BI was given if initial anesthesia was inadequate. Outcome variables included pain, which was rated by patients at 3 intervals using visual analogue scale, and lingual anesthesia and patients' satisfaction which were measured using 5-score verbal rating scale. Data analyses used were descriptive statistics, t test, χ2 test, and Pearson's correlation coefficient. P-value value less than 0.05 was considered significant. Results: There were 46 females and 34 males and the mean age was 35.3 years. All outcome variables were comparable between the two study groups (p˃0.05). Anesthesia was successful in 78% and 88% of cases in the (BI) and (BI+LI) groups respectively with no significant difference (p=0.2392). The mean articaine volume used was 2.5 ml and 2.87 ml respectively without significant difference (p=0.090). Conclusion: The anesthetic efficacy of (BI) alone and (BI+LI) of 4% articaine was comparable. When given in an adequate dose, articaine (BI) alone could be justified as an anesthetic option for the intra-alveolar extraction of mandibular molar teeth.

Objetivo: Investigar la efectividad anestésica de la infiltración bucal (BI) versus la infiltración bucal más lingual (BI+LI) de articaína al 4% para la extracción intraalveolar de molares mandibulares erupcionados. Material y Métodos: Ochenta pacientes fueron incluidos en este estudio clínico prospectivo. Se dividieron aleatoriamente en 1 de 2 grupos iguales: el primer grupo recibió BI de articaína al 4% 1,8 ml y LI de 0,5 ml, mientras que el segundo grupo recibió articaína al 4% 1,8 ml BI más 0,5 ml LI de solución salina normal. Se administró otro BI de articaína de 1,8 ml si la anestesia inicial era inadecuada. Las variables de resultado incluyeron el dolor, que los pacientes calificaron en 3 intervalos mediante una escala analógica visual, y la anestesia lingual y la satisfacción de los pacientes, que se midieron mediante una escala de calificación verbal de 5 puntos. Los análisis de datos utilizados fueron estadística descriptiva, prueba t, prueba χ2 y coeficiente de correlación de Pearson. Se consideró significativo el valor del valor de pinferior a 0,05. Resultados: Hubo 46 mujeres y 34 hombres y la edad media fue de 35,3 años. Todas las variables de resultado fueron comparables entre los dos grupos de estudio (p=0,05). La anestesia fue exitosa en el 78% y 88% de los casos en los grupos (BI) y (BI+LI) respectivamente sin diferencia significativa (p=0,2392). El volumen medio de articaína utilizado fue de 2,5 ml y 2,87 ml respectivamente sin diferencia significativa (p=0,090). Conclusión: La eficacia anestésica de (BI) solo y (BI+LI) de articaína al 4% fue comparable. Cuando se administra en una dosis adecuada, la articaína (BI) sola podría estar justificada para la extracción intraalveolar de molares mandibulares.

Assessment of the incidence and etiology of nosocomial diarrhea in a medical ward in Iraq.

This study aimed to detect the incidence, etiology, risk factors, and severity of nosocomial diarrhea among adult inpatients in a medical ward in Iraq. The study was conducted among patients admitted to the medical ward from June 1, 2019, to January 31, 2020, in AL-Sader medical city. The surveillance for nosocomial diarrhea was performed by monitoring every patient in the ward 3 times/week. 1050 patients were admitted to the medical ward in AL-Sader medical city. Of these, 52 patients (mean age 58±12.91 years, range 32 to 80) developed new-onset diarrhea during hospitalization. There was a significant relationship between the severity of diarrhea and age, residence, antibiotic use, including number and duration of antibiotics, immunosuppressive agents (steroids/chemotherapy), duration of hospital stay, level of consciousness, and enema use. Nosocomial diarrhea is a significant clinical problem that complicates about 5% of all admission in the medical ward. Various microorganisms account for nosocomial diarrhea, including E. histolytica, G. lamblia, and Candida. Several risk factors associated with the severe form of nosocomial diarrhea include old age, antibiotic use, immunosuppressive use, and length of hospital stay.

Looking beyond: complex holistic care needs of Syrian and Iraqi refugee children and adolescents.

OBJECTIVE: Protracted international conflict has seen escalating numbers of displaced and resettled Syrian and Iraqi refugees, raising concerns for their health and well-being. This paper describes the demographic and clinical profiles of recently resettled Syrian and Iraqi refugee children and adolescents across physical, psychosocial, developmental and educational domains using standardised multidisciplinary assessments. DESIGN: A cross-sectional observational study was undertaken of initial specialist paediatric multidisciplinary Refugee Health Service assessments completed at the tertiary paediatric hospital (Western Australia) between June 2015 and September 2019. RESULTS: Three hundred and twenty-seven children and adolescents (264 Syrian, 63 Iraqi) were assessed following resettlement. Witnessed trauma (86%) and disclosed adversity (median Refugee Adverse Childhood Experiences score 3, range 1-14) were universally high. Almost all patients had health issues identified across physical (99%), psychosocial (76%) and developmental/educational (75%) domains. Interrupted education (65%) and death of a family member (16%) were significantly associated with psychological morbidities. Common comorbidities included dental caries (78%), non-infectious disease (76%), vitamin D deficiency (72%), malnutrition (46%; overweight/obesity 23%), and psychological (32%; post-traumatic stress disorder 4.3%) and developmental (9.5%) concerns. Emerging and alarming child protection concerns were prevalent (17%), with females demonstrating especially high risks. CONCLUSION: This is the largest comprehensive study demonstrating the complex and cross-dimensional health needs and specific vulnerabilities of resettled Syrian and Iraqi refugee children and adolescents. Early comprehensive standardised multidisciplinary paediatric assessments, and culturally safe, trauma-informed interventions and follow-up are required to optimise resettlement outcomes and promote well-being.

Weaponised uranium and adverse health outcomes in Iraq: a systematic review.

BACKGROUND: The US military first deployed depleted uranium (DU) weapons in Iraq during the Gulf War in 1990 and in the 2003 invasion of Iraq. Research into the health impacts of DU has been mired in debate and controversy. Research funded by the US government has denied the health risks posed by DU to the Iraqi population, while opponents have claimed that DU is responsible for increased rates of birth defects and cancers in Iraq. Others assert that the public health impacts of DU weapons remain uncertain. This systematic review identified, appraised and synthesised all human observational studies assessing adverse health outcomes associated with DU exposure among the Iraqi population. To our knowledge, no systematic review has been conducted on the topic previously. METHODS: We searched 11 electronic databases for human observational studies published between 1990 and 2020 that measured association between exposure to weaponised uranium and health outcomes (including cancer, birth defects, immune system function and mortality) among the Iraqi population. We assessed risk of bias using the Navigation Guide's risk of bias tool and rated certainty of the evidence using the Grading of Recommendations, Assessment, Development and Evaluations approach (PROSPERO: CRD42018108225). RESULTS: Our searches identified 2601 records, of which 28 met our inclusion criteria. We identified five additional eligible reports from other sources. Two articles reported the results of multiple relevant studies; our final set included 33 articles reporting on 36 eligible studies. Most studies (n=30, 83%) reported a positive association between uranium exposure and adverse health outcomes. However, we found that the reviewed body of evidence suffers from a high risk of bias. CONCLUSION: The available evidence suggests possible associations between exposure to depleted uranium and adverse health outcomes among the Iraqi population. More primary research and the release of missing data are needed to design meaningful health and policy interventions in Iraq.

Screening and Preponderance of Peptic Ulcer and its Contributing Risk Factors Among Basrah City Residents in Iraq.

BACKGROUND: With the recent widespread use of over-the-counter drugs, there has been a noticeable increase in the occurrence of gastrointestinal discomfort and peptic ulcer disease. However, peptic ulcer is a highly complex disorder resulting from an imbalance between gastric destructive and protective factors. OBJECTIVE: To identify the risk factors of peptic ulcer disease. METHODS: This study was organized at Al-Basra teaching hospital and Al Sader teaching hospital in Basrah city, Iraq. Medical records and questionnaires were filled by patients undergoing diagnostic and therapeutic upper gastrointestinal endoscopies following their gastric discomfort complaints. Information related to patients, disease history, and medication history for six months prior to endoscopy procedures was collected. RESULTS: A total of 476 patients were identified, including 246 (51.7%) patients with endoscopically diagnosed peptic ulcers and 230 (48.3%) patients without peptic ulcers. The population was predominately male and there were significant differences between age groups. Smoking correlated with high relative risk; however, alcohol drinking had no significant role as a causative factor. The most extensively used drugs by patients who complained of peptic ulcers include NSAIDs, iron supplements, corticosteroids, and anti-platelet agents. A small number of patients were treated for hypertension and diabetes, which were correlated with peptic ulcer risks. The presence of H-pylori infections was significantly associated with peptic ulcer diagnosis. CONCLUSION: The risk of peptic ulcer disease appeared to increase with chronic medication use and smoking, which aggravate the contributing risk by H-pylori infections.

Impact of Petroleum Exposure on Some Hematological Indices, Interleukin-6, and Inflammatory Markers of Workers at Petroleum Stations in Basra City.

Background: Occupational and environmental exposure to several pollutant factors such as petroleum products containing benzene has toxic effects on different body systems. The hematopoietic system and immune system are among the affected systems. This study aims to investigate the effect of benzene exposure on some blood parameters of workers at several fuel stations in Basra city, as well as to reveal if the continuous exposure may induce an inflammatory response, which is reflected by changes in some hematological and inflammatory markers. Methods: The study included two groups of males. The first group consists of 72 exposed workers at petrol stations in different locations in the Basra city. The other group is the control group, which consists of 75 nonexposed subjects (students and faculty members of the college). Different hematological parameters (WBC, RBC, HGB, MCV, MCHC, and MCH) have been evaluated. Serum concentrations of IL-6 and hs-CRP were estimated in all workers and nonexposed using enzyme-linked immunosorbent assay (ELISA). Results: Data showed significant hematological changes in the exposed workers, and that anemia was a common disorder among them. Furthermore, there was a significant decline in WBC and different types of WBC including lymphocytes, monocytes, and neutrophils in the exposed workers. Erythrocyte sedimentation rate and serum levels of interleukin-6 and hs-CRP were significantly higher in exposed workers than in nonexposed. A significant correlation was identified among blood parameters, while a strong inverse correlation was identified between both MCHC and ESR. The most significant inverse correlation was found between RBC and IL-6 and MCH with hs-CRP. In addition, a significant negative correlation was found between monocytes and IL-6. Conclusion: The changes in all hematology and inflammatory parameters refer to damage in the hematopoietic system due to continuous exposure to vapors of petrol products, which also result in a significant increase in interleukin-6.

Effects of bodybuilding supplements on the kidney: A population-based incidence study of biopsy pathology and clinical characteristics among middle eastern men.

BACKGROUND: The incidence of kidney diseases among bodybuilders is unknown. METHODS: Between January 2011 and December 2019, the Iraqi Kurdistan 15 to 39 year old male population averaged 1,100,000 with approximately 56,000 total participants and 25,000 regular participants (those training more than 1 year). Annual age specific incidence rates (ASIR) with (95% confidence intervals) per 100,000 bodybuilders were compared with the general age-matched male population. RESULTS: Fifteen male participants had kidney biopsies. Among regular participants, diagnoses were: focal segmental glomerulosclerosis (FSGS), 2; membranous glomerulonephritis (MGN), 2; post-infectious glomeruonephritis (PIGN), 1; tubulointerstitial nephritis (TIN), 1; and nephrocalcinosis, 2. Acute tubular necrosis (ATN) was diagnosed in 5 regular participants and 2 participants training less than 1 year. Among regular participants, anabolic steroid use was self-reported in 26% and veterinary grade vitamin D injections in 2.6%. ASIR for FSGS, MGN, PIGN, and TIN among regular participants was not statistically different than the general population. ASIR of FSGS adjusted for anabolic steroid use was 3.4 (- 1.3 to 8.1), a rate overlapping with FSGS in the general population at 2.0 (1.2 to 2.8). ATN presented as exertional muscle injury with myoglobinuria among new participants. Nevertheless, ASIR for ATN among total participants at 1.4 (0.4 to 2.4) was not significantly different than for the general population at 0.3 (0.1 to 0.5). Nephrocalcinosis was only diagnosed among bodybuilders at a 9-year cumulative rate of one per 314 vitamin D injectors. CONCLUSIONS: Kidney disease rates among bodybuilders were not significantly different than for the general population, except for nephrocalcinosis that was caused by injections of veterinary grade vitamin D compounds.

Beta-Thalassemia Intermedia: A Single Thalassemia Center Experience from Northeastern Iraq.

OBJECTIVE: To determine the molecular characterization and disease-associated complications of beta-thalassemia intermedia (ß-TI) patients in Sulaymaniyah province, northeastern Iraq. METHODS: A total of 159 ß-TI) patients in Sulaymaniyah province, northeastern Iraq. ß-TI) patients in Sulaymaniyah province, northeastern Iraq. RESULTS: Nineteen different ß-globin gene mutations arranged in 37 various genotypes were determined. The most frequent were IVS-II-I (G>A) (47.2%), followed by IVS-I-6 (T>C) (23.3%) and IVS-I-110 (G>A) (5%). Among disease-related morbidities documented, bone disease amounted to 53% (facial deformity and osteoporosis), followed by endocrinopathies 17.6% (growth retardation and subclinical hypothyroidism), cholelithiasis 13.8%, pulmonary hypertension 11.3%, and abnormal liver function test 7.5%, whereas venous thrombosis, extramedullary hemopoiesis, and leg ulcer were less frequently observed. Age ≥ 35 and female sex were risk factors for cholelithiasis, while age was an independent risk for hypothyroidism and female sex was associated with increased risk for osteoporosis. Mean serum ferritin of ≥1000 µg/L was associated with an increased risk of osteoporosis, whereas chelation therapy was protective for a multitude of other complications. Transfusion, on the other hand, increased the risk of osteoporosis, yet it was protective for cholelithiasis and hypothyroidism. Moreover, splenectomy was protective for cholelithiasis, although it was an independent risk for hypothyroidism. Finally, hydroxyurea was associated with an increased risk of osteoporosis, while it was protective for cholelithiasis. Discussion and Conclusion. ß +-thalassemia mutation had contributed to 41.25 of families with a less severe ß-thalassemia phenotype in the northeastern part of Iraq, justifying the need to investigate the contribution of genetic modifiers in ameliorating disease severity. In addition, the substantial number of ß-TI patients developed disease-related morbidities, which necessitates the need for more appropriate clinical management with earlier intervention.ß-TI) patients in Sulaymaniyah province, northeastern Iraq. µg/L was associated with an increased risk of osteoporosis, whereas chelation therapy was protective for a multitude of other complications.

Increased PTEN gene expression in patients with endometrial carcinoma from areas of high risk depleted uranium exposure.

OBJECTIVE: Investigate PTEN gene expression and tumor aggressiveness in endometrial carcinoma specimens from patients living in either areas of depleted uranium [DU] pollution or unpolluted regions to determine any evidence for the effect of war pollution on the rising trends of cancer incidence in Iraq. RESULTS: Tumor PTEN gene expression was significantly increased in patients living in the areas of high risk DU exposure, in comparison to patient tumors from low risk areas [P = 0.001]. The age distribution between the potentially DU exposed (55.09 ± 1.24) and unexposed subjects 56.38 ± 1.18) was not significant [P = 0.45]. Endometrial carcinoma aggressiveness was equivalent in both subject groups, with no significant differences in either tumour grade and [P = 0.286] stage distribution [P = 0.98]. Finally, there were no significant differences between the potentially exposed and unexposed subjects with regard to cervical [P = 0.532] or to ovarian involvement [P = 0.518]. The results linked environmental war pollutants [DU] to alterations in PTEN gene expression in endometrial carcinoma. Furthermore, this finding may explain the overall increasing cancer trends observed in Iraq. Strategies should be considered for the therapeutic targeting of cancers with elevated PTEN gene expression to improve patient outlook.

Treatment Outcomes of Pediatric Patients With Ewing Sarcoma in a War-Torn Nation: A Single-Institute Experience From Iraq.

PURPOSE: Ewing sarcoma (ES) is a relatively rare, highly malignant tumor of the musculoskeletal system. It is the second most common malignant bone tumor in children and adolescents in the age group of 5 to 20 years. The aim of this study was to identify the treatment outcomes of pediatric patients with ES in Sulaimani governorate, Iraq. PATIENTS AND METHODS: This was a retrospective study that reviewed the medical records of pediatric patients with ES who were managed between 2009 and 2015, with follow-up until late 2017. Patient- and tumor-related factors were correlated with clinical outcomes. RESULTS: A total of 31 pediatric patients with ES were included in this study. All the patients received chemotherapy and radiotherapy, whereas only 14 patients underwent surgical resection and just eight had free surgical margins. The median age at diagnosis was 13 years, 58% were male, and 42% were female. The presenting symptoms at diagnosis were mostly pain (67.7%) and palpable mass (25.8%). The primary tumor was located in the extremities (51.6%), the thoracic cage (19.4%), the pelvis (16.1%), and the lumbar vertebrae (12.9%). Approximately two thirds of the patients (61.3%) had localized disease at the time of presentation. The 5-year overall survival was 19%, and the 5-year recurrence-free survival was 34%. CONCLUSION: Clinical outcomes of ES in pediatric patients in our war-torn nation, Iraq, are still markedly inferior to the published outcomes from stable, developed nations. Additional large and multicenter national studies are required. Diagnostic and therapeutic measures need improvement, and multidisciplinary and comprehensive cancer-integrated approaches are vital for better outcomes.

Cavisoma magnum (Cavisomidae), a unique Pacific acanthocephalan redescribed from an unusual host, Mugil cephalus (Mugilidae), in the Arabian Gulf, with notes on histopathology and metal analysis.

Cavisoma magnum (Southwell, 1927) Van Cleave, 1931 was originally described from a sea bass, Serranus sp. and spotted surgeonfish, Ctenochaetus strigosus (Perciformes) off Sri Lanka before its more recent redescription from milkfish in the Philippines in 1995. These reports were based on only light infections of their host fishes. Of the few flathead grey mullets, Mugil cephalus (Mugilidae), that we examined in the Arabian Gulf, one fish was infected with 1,450 worms. One milkfish, Chanos chanos (Chanidae), from the same location in the Arabian Gulf, was also heavily infected with specimens of C. magnum. The descriptions of this unique large worm are revised and for the first time, we provide SEM images, new systematic observations, metal analysis of hooks showing extremely high levels of sulfur, and histopathology in the mullet intestinal tissue. Adjustments and corrections of previous descriptive accounts are made. The histopathology studies show extensive damage to the host intestinal tissue including epithelial necrosis, hemorrhaging and worm encapsulation. There is an extensive amount of host connective tissue surrounding the worm. Results of x-ray analysis displayed high levels of sulfur in proboscis hooks, especially at the tips and edges of these attachment structures.

Effect of Oral Zinc Supplementation on the Thiol Oxido-Reductive Index and Thiol-Related Enzymes in Seminal Plasma and Spermatozoa of Iraqi Asthenospermic Patients.

A thiol group plays an essential role in sperm metabolism and the antioxidative defense state. Zinc is the second most abundant element in the human body, following iron. The present study was conducted to study the effect of zinc supplementation on the characteristics of semen along with thiol and thiol-related enzymes in semen of asthenospermic patients. Semen samples were obtained from 60 fertile and 60 asthenospermic men, from couples who had consulted the infertility clinic of Babil Hospital (Hillah city, Iraq). The subfertile group was treated with zinc; every participant took two 220 mg capsules of zinc sulfate per day for 3 months. Semen samples were obtained (before and after zinc supplementation). The levels of reduced thiol, oxidized thiol, thiol oxido-reductive index, and thiol-related enzymes activities were determined in spermatozoa and seminal plasma of patients and healthy groups. Oxidized thiol levels were significantly higher in the infertile patients compared to that in the fertile group. Conversely, reduced thiol level, sulfhydryl oxidase activity, and glutathione peroxidase activity significantly decreased in the infertile patients compared to that in the fertile group. Oxidized thiol levels, reduced thiol levels, and thiol-related enzymes activities of the infertile patients were restored to normal values after treatment with zinc. However, reduced and oxidized thiol levels in spermatozoa did not change significantly in the group treated with zinc. The quantitative values for RSH/RSSR and thiol-related enzymes may provide useful means to qualitatively express the oxidant/antioxidant balance in clinical and epidemiologic studies.

Use of complementary and alternative medicine in pregnancy: a cross-sectional survey on Iraqi women.

BACKGROUND: Due to the lack of strong evidence on safety and efficacy of complementary and alternative medicine (CAM) approaches, the use of CAM in women during pregnancy could be hazardous for mother and fetus. Meanwhile, little is known regarding the patterns, the reasons and the factors affecting use of CAM among pregnant women in Iraq. METHODS: A cross sectional survey design was used to carry out face-to-face interviews with 335 consecutive pregnant women. The questionnaire comprised of three sections: socio-demographic characteristics, pregnancy-related aspects and the patterns and attitudes towards use of CAM. Determinants of CAM use were assessed through the logistic regression analysis. RESULTS: Three hundred thirty-five pregnant women completed the questionnaire. 56.7 % reported using at least one form of CAM modalities. In total, 24 different types of CAM were used; with herbal medicine (53.7 %) and multivitamins (36.3 %) the most commonly used modalities. From the logistic regression analysis, the variables positively associated with CAM use were: rural residence (odds ratio (OR) 2.0, p < 0.01), no occupation (OR 2.7, p < 0.05), high income (OR 2.0, p < 0.05), perceived healthy status (OR 2.6, p < 0.05) and ever use of contraception (OR 2.0, p < 0.01). Only 0.5 % of CAM users disclosed their CAM use to physicians. CONCLUSIONS: The proportion of CAM users among pregnant women is relatively high and it is important to learn what types of CAM they use. However, disclosure of CAM use was extraordinarily low. Given the low rate of disclosure, it should be ensured that physicians establish good level of communication with pregnant women and have adequate knowledge of CAM.

Study of the effects of oral zinc supplementation on peroxynitrite levels, arginase activity and NO synthase activity in seminal plasma of Iraqi asthenospermic patients.

BACKGROUND: Low concentrations of nitric oxide (NO) are necessary for the biology and physiology of spermatozoa, but high levels of NO are toxic and have negative effects on sperm functions. Although several studies have considered the relationship between infertility and semen NO concentrations, no study on the effects of asthenospermia treatments such as oral zinc supplementation on concentrations of NO, which are important in fertility, has been reported. Studies have shown that oral zinc supplementation develops sperm count, motility and the physical characteristics of sperm in animals and in some groups of infertile men. The present study was conducted to study the effect of zinc supplementation on the quantitative and qualitative characteristics of semen, along with enzymes of the NO pathway in the seminal plasma of asthenospermic patients. METHODS: Semen samples were obtained from 60 fertile and 60 asthenozoospermic infertile men of matched age. The subfertile group was treated with zinc sulfate; each participant took two capsules (220 mg per capsule) per day for 3 months. Semen samples were obtained (before and after zinc sulfate supplementation). After liquefaction of the seminal fluid at room temperature, routine semen analyses were performed. The stable metabolites of NO (nitrite) in seminal plasma were measured by nitrophenol assay. Arginase activity and NO synthase activity were measured spectrophotometrically. RESULTS: Peroxynitrite levels, arginase activity, NO synthase activity and various sperm parameters were compared among fertile controls and infertile patients (before and after treatment with zinc sulfate). Peroxynitrite levels and NO synthase activity were significantly higher in the infertile patients compared to the fertile group. Conversely, arginase activity was significantly higher in the fertile group than the infertile patients. Peroxynitrite levels, arginase activity and NO synthase activity of the infertile patient were restored to normal values after treatment with zinc sulfate. Volume of semen, progressive sperm motility percentage and total normal sperm count were increased after zinc supplementation. CONCLUSIONS: Treatment of asthenospermic patients with zinc supplementation leads to restored peroxynitrite levels, arginase activity and NO synthase activity to normal values and gives a statistically significant improvement of semen parameters compared with controls.

Female genital mutilation in Iraqi Kurdistan: description and associated factors.

The high prevalence of female genital mutilation has been a concern in Iraqi Kurdistan. This study was undertaken to estimate its prevalence and describe factors associated with its occurrence. A cross-sectional survey was undertaken from March to April 2011 of females aged up to 20 years using interviews and clinical examination. The survey included 1,508 participants with mean age of 13.5 years (SD 5.6). Overall female genital mutilation prevalence was 23%, and the mean age at which it had been performed was 4.6 years (SD 2.4). Type I (partial or total removal of the clitoris) comprised 76% of those who had had female genital mutilation; in 79% of cases the decision to perform it was made by the mother; and in 54% of cases it was performed by traditional birth attendants/midwives. Women aged 16 years and over were more likely to have had female genital mutilation compared to children aged below 6 years (OR 11.9, p < .001). Children of uneducated mothers were eight times as likely to have had genital mutilation compared to children of mothers with over nine years of education (OR 8.0, p < .001). Among women aged 17 years and younger, 34% of those who were married had been circumcised versus 17% of those who were not married (p < .001). Participants residing in the northeast of Kurdistan region were more likely to have been circumcised. The study results show that female genital mutilation is a frequent practice in Iraqi Kurdistan. Attention and intervention is needed to address this aspect of the well-being of girls and women.

Environmental pollution by depleted uranium in Iraq with special reference to Mosul and possible effects on cancer and birth defect rates.

Iraq is suffering from depleted uranium (DU) pollution in many regions and the effects of this may harm public health through poisoning and increased incidence of various cancers and birth defects. DU is a known carcinogenic agent. About 1200 tonnes of ammunition were dropped on Iraq during the Gulf Wars of 1991 and 2003. As a result, contamination occurred in more than 350 sites in Iraq. Currently, Iraqis are facing about 140,000 cases of cancer, with 7000 to 8000 new ones registered each year. In Baghdad cancer incidences per 100,000 population have increased, just as they have also increased in Basra. The overall incidence of breast and lung cancer, Leukaemia and Lymphoma, has doubled even tripled. The situation in Mosul city is similar to other regions. Before the Gulf Wars Mosul had a higher rate of cancer, but the rate of cancer has further increased since the Gulf Wars.

Oral zinc supplementation restores high molecular weight seminal zinc binding protein to normal value in Iraqi infertile men.

BACKGROUND: Zinc in human seminal plasma is divided into three types of ligands which are high (HMW), intermediate (IMW), and low molecular weight ligands (LMW). The present study was aimed to study the effect of Zn supplementation on the quantitative and qualitative characteristics of semen along with Zinc Binding Protein levels in the seminal plasma in asthenozoospermic patients. METHODS: Semen samples were obtained from 37 fertile and 37 asthenozoospermic infertile men with matched age. The subfertile group was treated with zinc sulfate, every participant took two capsules per day for three months (each one 220 mg). Semen samples were obtained (before and after zinc sulfate supplementation). After liquefaction seminal fluid at room temperature, routine semen analyses were performed. For determination of the amount of zinc binding proteins, the gel filtration of seminal plasma on Sephadex G-75 was performed. All the fractions were investigated for protein and for zinc concentration by atomic absorption spectrophotometry. Evaluation of chromatograms was made directly from the zinc concentration in each fraction. RESULTS: A significant high molecular weight zinc binding ligands percentage (HMW-Zn %) was observed in seminal plasma of fertile males compared with subfertile males. However, seminal low molecular weight ligands (LMW-Zn) have opposite behavior. The mean value of semen volume, progressive sperm motility percentage and total normal sperm count were increased after zinc sulfate supplementation. CONCLUSIONS: Zinc supplementation restores HMW-Zn% in seminal plasma of asthenozoospermic subjects to normal value. Zinc supplementation elevates LMW-Zn% in seminal plasma of asthenozoospermic subjects to more than normal value. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT01612403.

Metal contamination and the epidemic of congenital birth defects in Iraqi cities.

Between October 1994 and October 1995, the number of birth defects per 1,000 live births in Al Basrah Maternity Hospital was 1.37. In 2003, the number of birth defects in Al Basrah Maternity Hospital was 23 per 1,000 live births. Within less than a decade, the occurrence of congenital birth defects increased by an astonishing 17-fold in the same hospital. A yearly account of the occurrence and types of birth defects, between 2003 and 2011, in Al Basrah Maternity Hospital, was reported. Metal levels in hair, toenail, and tooth samples of residents of Al Basrah were also provided. The enamel portion of the deciduous tooth from a child with birth defects from Al Basrah (4.19 µg/g) had nearly three times higher lead than the whole teeth of children living in unimpacted areas. Lead was 1.4 times higher in the tooth enamel of parents of children with birth defects (2,497 ± 1,400 µg/g, mean ± SD) compared to parents of normal children (1,826 ± 1,819 µg/g). Our data suggested that birth defects in the Iraqi cities of Al Basrah (in the south of Iraq) and Fallujah (in central Iraq) are mainly folate-dependent. This knowledge offers possible treatment options and remediation plans for at-risk Iraqi populations.

Predicting acute viral hepatitis serum markers (A and E) in patients with suspected acute viral hepatitis attending primary health care centers in Baghdad: a one year cross-sectional study.

BACKGROUND: Viral hepatitis is an important preventable infectious disease with various rates of occurrence in different areas of the world. The main objective of the present study was to evaluate the role of some risk factors in predicting a positive acute viral hepatitis marker among patients with suspected acute viral hepatitis in a primary health care setting in Baghdad. Besides, finding out the occurrence of jaundice, contribution of viruses A and E to the cases that have occurred in Baghdad province was also searched for. METHODS: Over a period of 1 year a descriptive cross sectional study was carried out at the primary health care centers in Baghdad. A questionnaire form was used to collect data about demographic factors and the results of the investigations. Total serum bilirubin and bilirubin in urine were done at the primary health care center laboratory. The rest of the sera samples were sent to Hepatitis referral Lab at Central Public Health Laboratory (CPHL) to be tested for anti HAV IgM and anti HEV IgM using ELISA technique. RESULTS: A total of 7,576,372 consultations to primary health care centers were recorded in Baghdad. Among those a total of 2,692 cases (35.5 per 100,000 consultations) were labeled as acute viral hepatitis cases. A positive hepatitis viral marker (A, B, C and E) was found in 1,332 cases (17.6 per 100,000 consultations). More than two fifths (44.8%) of cases were positive for anti-HAV antibodies and another 1.6% had positive anti-HEV antibodies. CONCLUSION: During 1 year period, the rate of occurrence of suspected acute viral hepatitis cases was 35.5 per 100000 of consultations to the primary health care centers in Baghdad. Of the total suspected cases, only 17.6 per 100000 of the consultations were positive for one of the viral hepatitis markers. Those who tested positive for one of the viral hepatitis markers represent 49.5% of the suspected cases. Proportion of anti HAV IgM positive tests among suspected cases was 44.8%. Factors that were able to predict positive Anti HAV IgM were (younger age group, negative history of cupping or tattooing, negative past history of jaundice). Male gender was the least important predictor of a positive case for anti HAV IgM. Proportion of Anti HEV IgM positive tests among suspected cases was 1.6%. Of the factors studied, only age was able to predict a positive Anti HEV IgM in those more than 15 years. Further studies are recommended.
