Gender determination is an important step in identification in forensic medicine. CT measurements of maxillary sinuses may be useful to support gender identification. This study was undertaken to study the accuracy and reliability of maxillary sinus dimensions measurement in gender classification through the use of reconstructed helical CT images. Eighty-eight patients (43 men and 45 women) with age range from 20 to 49 years were selected in this study. The width, length, and height of the maxillary sinuses in addition to the total distance across both sinuses were measured. Data were subjected to discriminant analysis for gender using multiple regression analysis. Maxillary sinus height was the best discriminant parameter that could be used to study sexual dimorphism with an overall accuracy of 71.6%. Using multivariate analysis, 74.4% of male sinuses and 73.3% of female sinuses were sexed correctly. The overall percentage for sexing maxillary sinuses correctly was 73.9%. It can be concluded that reconstructed CT image can provide valuable measurements for maxillary sinuses and could be used for sexing when other methods of sexing are not conclusive.

Background and objective: Viral Hepatitis Type B&C is serious public health challenge throughout the world.Hepatitis B and C viruses still remain to be the major causes of chronic hepatitis.It is estimated that around 350-400 million people in the world are chronic carriers of HBV, which represents approximately 7% of the total populationwhereas infection with HCV is found in approximately 3% of the world population, which represents 160 million people. Hepatitis B infection has a wide range of seroprevalence in the Mediterranean countries ranging from intermediate (=>2% ) to high prevalence ( =>7%). World Health Organization estimated a prevalence rate for HCV infection of about 4.6% in Eastern Mediterranean in 1999. During the eightieths years of the last century, Iraq was considered to be of intermediate endemicity with hepatitis B as reflected by 3% seroprevalence of HBsAg in normal population. Hepatitis C was found to be of low endemicity among blood donors 0.5%. There were no national wide epidemiological studies regarding the prevalence of hepatitis B&C accordingly we conduct this study to determine the prevalence of both types all over the Iraq. Methods: From the 1 st of January 2005 to 31 st of December 2006, a community based cross-sectional study was conducted all over Iraqi governorates. A total of 9610 persons, recruited by surveying a nationally representative random sample of households were analyzed. A stratified random sample proportional to size of each of the 18 Iraqi governorates, both urban and rural areas were included. Prevalence estimates were therefore weighted and age-adjusted. Five (5ml) of blood samples were taken from the study subjects, and tested for hepatitis B surface antigen, antibody to hepatitis B core antigen antibody to hepatitis B surface antigen and hepatitis C antibodies . Results:The national prevalence rate of HBs Ag was 1.6% and correlated positively with age. The prevalence rate of anti-HBs antibodies was 17%. The prevalence of anti-HBc was 9.7%. The prevalence of anti-HCV was low (0.4%). The prevalence rate of anti-HBs antibodies in <10 years children is only 32.2%, which raise the issue of incomplete coverage of hepatitis B vaccine during the years preceding the study years. Conclusion:The findings revealed that Iraq is of low prevalence with HBsAg.On the other hand,hepatitis C was found to be of very low prevalence. As a marker of exposure to hepatitis B, Anti HBcIgG was found to increase with age.

Hepatitis, an inflammation of the liver, has a number of infectious and non-infectious causes. Two of the viruses that cause hepatitis (hepatitis A and E) can be transmitted through water and food; hygiene is therefore important in their control. First, to assess the importance of HAV and HEV as a possible diagnosis for clinically diagnosed patients with acute viral hepatitis. Second, to assess the prevalence of hepatitis A and E in all provinces of Iraq and study its association with age, gender. This study consisted of two groups: The first group consisted of 2975 patients with a clinical diagnosis of acute viral hepatitis. The second group consisted of a total of 9610 persons, which were recruited by surveying a nationally representative random sample of households. A stratified random sample proportional to size of each of the 18 Iraqi governorates, both urban and rural areas was employed. Blood samples were taken from study subjects. The relative frequency of positive anti-HAV IgM antibodies was 41.0%, while anti-HEV IgM represented 19.4 % of patients with a clinical suspicion of acute viral hepatitis. The prevalence of hepatitis A-IgG antibodies in Iraqi population is 96.4% (95% confidence interval is 96-96.8%), while that of Hepatitis E-IgG antibodies was 20.3 % (95% confidence interval is 19.4-21.2%). The sero-prevalence showed a steady and significant increase with age for hepatitis E, while it showed an obvious increase between the first and second decade of life for HAV. No significant sex variation was observed for HAV, while males had a higher risk (by 15%) for HEV. The after war situation in Iraq is disastrous, due to the damage to water supply infrastructure and its contamination with sewage, Hepatitis A is hyper endemic in Iraq, while hepatitis E is endemic. Among patients with a clinical diagnosis of acute viral hepatitis, two fifths had serologic evidence of type A and another one fifth had type E viral hepatitis.

Objective: To determine the feasibility and acceptability of mobile health technology and its potential to improve antenatal care (ANC) services in Iraq. Methods: This was a controlled experimental study conducted at primary health care centers. One hundred pregnant women who attended those centres for ANC were exposed to weekly text messages varying in content, depending on the week of gestation, while 150 women were recruited for the unexposed group. The number of ANC visits in the intervention and control groups, was the main outcome measure. The Mann-Whitney test and the Poisson regression model were the two main statistical tests used. Results: More than 85% of recipients were in agreement with the following statements: "the client recommends this program for other pregnant women", "personal rating for the message as a whole" and "obtained benefit from the messages". There was a statistically significant increase in the median number of antenatal clinic visits from two to four per pregnancy, in addition to being relatively of low cost, and could be provided for a larger population with not much difference in the efforts. Conclusions: Text messaging is feasible, low cost and reasonably acceptable to Iraqi pregnant women, and encourages their ANC visits.

Objectives: Rheumatoid arthritis (RA) is a common chronic inflammatory arthropathy of unknown etiology. Trace elements have a great role in a number of biological processes. The aim of this study was to assess the serum element boron in a sample of Iraqi patients with RA and to evaluate its relationship if present with disease activity, functional class of the disease, and rheumatoid factor (RF). Methods: A cross sectional study enrolled 107 RA patients and 214 controls matched in age and sex. The American College of Rheumatology 1987 revised criteria was used for diagnosis of RA. Disease Activity Score index of 28 joints (DAS28), functional class of RA patients, RF, erythrocyte sedimentation rate (ESR) were measured in patients’ group; serum boron levels were measured using a flame atomic absorption spectrophotometer in both patients and controls groups. Results: RA patients had significantly lower serum boron level than controls (P < 0.001). Serum boron level was significantly negatively correlated with RF titer in RA patients (r = –0.22, P = 0.001). No significant correlation was found between serum boron with DAS28, disease functional class, and ESR (P > 0.05). Also, RF titer was a significant predictor of low serum boron level (P = 0.023, OR = –0.07, 95%CI –0.13-(–0.01)). Conclusions: There was a significant low serum boron level in RA patients. RF titer was significant predictor of low serum boron level. This may suggest that boron element may play a role in pathophysiology of RA and its severity. Supplementation with boron element and diets rich in fruits, vegetables, nuts, and pulses may be useful. [J Exp Integr Med 2013; 3(1): 9-15

Objective. Systemic lupus erythematous (SLE) is a systemic autoimmune disease, and both genetic and environmental factors are implicated in its pathogenesis. The aim of this study was to assess cellular and nuclear morphology of SLE using a buccal micronucleus cytome assay.Methods. This study included 58 SLE patients and 58 healthy age-and sex-matched controls. Patients' baseline characteristics were recorded, and a buccal micronucleus cytome assay was used to measure cellular and nuclear abnormalities in both groups.Results. Significantly higher frequencies of micronuclei, nuclear buds, binucleated cells, basal cells, condensed chromatin cells, karyorrhectic cells, pyknotic cells, and karyolytic cells were seen in SLE patients as compared to controls. A buccal micronucleus cytome assay score of >4 had the highest accuracy (93.1%), almost perfect positive predictive value (98.1% at 50% pretest probability and 99.8% at 90% pretest probability), 87.9% sensitivity, and 98.3% specificity for the diagnosis of SLE.Conclusion. Biomarkers of DNA damage, proliferative potential, and cell death were significantly increased in SLE patients. The buccal micronucleus cytome assay was a valid and easy way for clinicians to assess individuals at high risk of developing SLE.Systemic lupus erythematosus (SLE) is a multisystem autoimmune disorder with a variety of proposed pathogeneses. Apoptosis is one of several important mechanisms involved in the pathogenesis of SLE. A previous study has demonstrated that lymphocyte apoptosis is increased and removal of apoptotic cells is impaired in SLE. Furthermore, apoptosis was found to be higher in active SLE as compared to inactive SLE (1).Several lines of evidence have demonstrated the close relationship between apoptosis and autoantibodies. Delayed clearance of apoptotic residue, such as histone H3, may result in the activation of antigenpresenting cells and the formation of autoantibodies; further, the antigenicity of autoantibodies is mostly against apoptotic cells (2). Studies have linked lymphocyte and leukocyte apoptosis with SLE and titers of autoantibodies (3).The buccal micronucleus cytome assay is a noninvasive method used to study DNA damage, chromosomal instability, cell death, and the regenerative potential of human buccal mucosal tissue (4). To our knowledge, no studies have as yet assessed buccal cell micronuclei in patients with connective tissue diseases or inflammatory arthritis. This study was designed to assess cellular and nuclear morphology in SLE using a buccal micronucleus cytome assay. PATIENTS AND METHODSStudy design. This case-control study was conducted at the Baghdad Teaching Hospital Rheumatology Unit from September 2012 to May 2013. We screened SLE patients who were eligible for inclusion in the study and then compared patients to matched healthy controls; buccal micronucleus cytome biomarkers were measured in both groups. Informed consent was obtained from all participants, and this study was approved by the ethics committee of Baghdad University, College...

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.
