Background:
tuberculosis is an endemic disease in Yemen. Abdominal Tuberculosis (AT) is the most common extra pulmonary manifestation of the disease.The clinical picture
can be non specific.Laparoscopy is the most accurate diagnostic method but has its limitation depending on presentation.
The aim of this study was to present the common clinical manifestation and the different type of Abdominal TB,the surgical procedure used,the morbidity and
mortality of the disease.
Patient and Methods:
This is a prospective study of 48 patients with Abdominal TB who were admitted to Kuwait University hospital in Sana'a-Yemen between Jan 2002-Dec
2004.fourteen patients (29%) were treated medically with Anti TB drugs.Thirty four patients (71%) required surgical Intervention for diagnosis and treatment.
Results :
Thirty two patients (67%) were female ,16 patients ( 33%) were male with a ratio of 2:1 .Fifty percent of patients were in age group 20-40.The most common
symptom was Anorexia (94%) abdominal pain (92%) fever (90%).The most common signs were Abdominal mass ,ascitis and abdominal tenderness.Smeares
and culture of ascitis fluid were negative for A.F.B. Out of the 34 patients who required surgical treatment ;17 patients (50%) had Tuberculous peritonitis,32% had tuberculosis of intestine, and 17%had tubeculous mesenteric lymphadenitis.Complication rate was 50%,and mortality was 9%.
Conclusions:
Diagnosis of Abdominal TB should be suspected in patients of abdominal pain with vague clinical presentation coming from endemic areas.not all patients present
with ascitis and whene ascitis is present smears and culture are usually negative for A.F.B. Laparoscopy has its limitation Surgery should be avoided unless complication
occur and should be conservative.Tube drains can be used with no fear of TB Sinus.
In this paper, a Bayesian analysis is made to estimate the Reliability of two stress-strength model systems. First: the reliability of a one component strengths X under stress Y. Second, reliability of one component strength under three stresses. Where X and Y are independent generalized exponential-Poison random variables with parameters (α,λ,θ) and (β,λ,θ) . The analysis is concerned with and based on doubly type II censored samples using gamma prior under four different loss functions, namely quadratic loss function, weighted loss functions, linear and non-linear exponential loss function. The estimators are compared by mean squared error criteria due to a simulation study. We also find that the mean square error is
... Show MoreThe comparison of double informative priors which are assumed for the reliability function of Pareto type I distribution. To estimate the reliability function of Pareto type I distribution by using Bayes estimation, will be used two different kind of information in the Bayes estimation; two different priors have been selected for the parameter of Pareto type I distribution . Assuming distribution of three double prior’s chi- gamma squared distribution, gamma - erlang distribution, and erlang- exponential distribution as double priors. The results of the derivaties of these estimators under the squared error loss function with two different double priors. Using the simulation technique, to compare the performance for

Show MoreIn this paper, we used maximum likelihood method and the Bayesian method to estimate the shape parameter (θ), and reliability function (R(t)) of the Kumaraswamy distribution with two parameters l , θ (under assuming the exponential distribution, Chi-squared distribution and Erlang-2 type distribution as prior distributions), in addition to that we used method of moments for estimating the parameters of the prior distributions.

this study aimed to study the effect of Cordia myxa extract on the growth and activities of the following types of bacteria : Escherichia coli , Pseudomonas aeruginosa, Proteus Spp., Klebsiella pneumoniae , Staphylococcus aureus, Streptococcus pyogenes , Bacillus subtilus, and the yeast Candida albicans .the results showed an inhibitory effect of the methanol extract on both the growth and activity of the tested microbes .this was reflected by the minimum inhibitory concentration ( MIC ) of different type of bacteria and the yeast.
