Research summary
تتناول هذه الدراسة تحليل الجراثيم المسببة لالتهاب المجاري البولية لدى الإنسان، بالإضافة إلى دراسة حساسيتها تجاه المضادات الحيوية. تم جمع 120 عينة بول من مرضى يعانون من أعراض التهاب المجاري البولية في مستشفى الأمين بحمص وعيادات خارجية بين يوليو وأكتوبر 2016. أظهرت النتائج أن 100 عينة كانت موجبة للزرع الجرثومي، مع نسبة إصابة أعلى بين الإناث مقارنة بالذكور بنسبة 3:1. كما أظهرت الدراسة أن 28% من المصابين كانوا يعانون من مرض السكري، وأن 44% من النساء المصابات كن حوامل. تم تحديد أنواع الجراثيم باستخدام أوساط زرعية واختبارات كيميائية حيوية، حيث كانت E.coli هي الأكثر شيوعاً بنسبة 60%، تليها Staphylococcus وKlebsiella بنسبة 16% لكل منهما، ثم Enterobacter وPseudomonas بنسبة 8% لكل منهما. أظهرت النتائج تبايناً في استجابة الجراثيم للمضادات الحيوية، حيث أبدت E.coli مقاومة عالية تجاه CTX وCRO بنسبة 67%، بينما كانت حساسة بنسبة 73% تجاه AMK. أظهرت Enterobacter مقاومة بنسبة 38% تجاه CTX وCRO، وحساسية بنسبة 100% تجاه AMK وF. أبدت Klebsiella مقاومة بنسبة 50% تجاه CIP، وحساسية بنسبة 75% تجاه AMK وNOR وF. أظهرت Staphylococcus مقاومة بنسبة 50% تجاه AMK، وحساسية بنسبة 100% تجاه CIP وCTX وCRP. أظهرت Pseudomonas مقاومة بنسبة 100% تجاه CTX وCRP، وحساسية بنسبة 75% تجاه NOR وGN. توصي الدراسة بضرورة إجراء اختبار الحساسية للمضادات الحيوية قبل التداوي بها لتقليل ظهور سلالات مقاومة.
Critical review
تعتبر هذه الدراسة قيمة في تسليط الضوء على الجراثيم المسببة لالتهاب المجاري البولية وحساسيتها تجاه المضادات الحيوية. ومع ذلك، يمكن تحسين الدراسة من خلال توسيع نطاق العينة لتشمل مناطق جغرافية مختلفة لزيادة تنوع البيانات. كما يمكن استخدام تقنيات حديثة مثل تحليل الجينوم الكامل للجراثيم لفهم أفضل لآليات المقاومة. بالإضافة إلى ذلك، يمكن تضمين دراسة تأثير العوامل البيئية والصحية الأخرى على انتشار الجراثيم ومقاومتها للمضادات الحيوية.

Ninety urin samples were taken from patients suffering from
urinary tract infection .the purpose was to isolate and identify Ecoli.
After cultural and biochemical diagnosis,[47] isolates had been
obtained with [63.5%] for E-coli out of [74] samples that had
bacterial growth.
Objective:
Evaluate sensitivity and specificity of nitrite test to urine culture(gold standard) for
diagnosing urinary tract infection in patients with sickle cell anemia with urinary
symptoms and signs.
Methods:
The study sample included 79 chi
ldren aged 2 to 14 years with SCA presenting with
fever (temperature >38°C),abdominal pain, urgency, dysuria or increased urinary
frequency who referral to the general pediatric clinic and the children's ambulance
department in Tishreen University Hospital in Lattakia during( 2016-2017).
Midstream urine specimen was collected from children. Samples were subjected to nitrite
test, culture and sensitivity.
Results :
There was significant bacteriuria in 17 (21.5%) children with SCA. A positive test
for nitrite was obtained in 12 of the 17(70.5%) children. The nitrite test has a specificity of
95.2% in detecting bacteriuria, a sensitivity of 70.6%, a positive predictive value of 80%
and a negative predictive value of 92%. A positive nitrite test was significantly associated
with bacteriuria, while a negative test was also significantly associated with an absence of
bacteriuria.
204 samples were collected from various body samples
during the year 2016. These 204 samples distributed as
follows: 133 from urine , 37 swabs of wounds and burns,
10 swabs from the ear and pharynx, 12 from feces, 8
from CSF, 4 from blood. This s
tudy distinctly showed that
gram negative bacilli were the most isolates 136 (67%)
while 68 isolates (33%) were gram positive bacteria .
E. coli dominated (39.68%) of the total gram negative
bacilli.
This study distinctly showed an increase in the ratio of
E. coli resistance to one or more types of antibiotics , we
found that E. coli resistance to all antibiotics except
specific and expensive antibiotics, and we found that its
complete resistance to the second ,third and fourth
generation of cephalosporins , resistance to specific and
antibiotics such as Imipenem.
A total of 73 drinking water samples were collected from distribution
system in Lattakia city, the aim was to search for hetrotrophic bacteria and
investigate their resistance to chlorine and antibiotics. The antibiotic
susceptibility tests were:
carried out by using agar dillution method (MIC) and
the antibiotics tested were: Ampicillin, Chloramphenicol, tetracycline,
Amikacin, Ciprofloxacin, Cefotaxim, Gentamicin, Erythromycin Piperacilin/
Tazobactam, and cephalothin.
A sum of 133 bacterial strains were isolated and included by five genera:
pseudomonas, acinetobacter, flavobacter, chromobacter, and methylobacter.
The samples content of residual chlorine were ranged between 0.1 to 3.8 mg/l.
The majority of bacterial strains isolated were resistance to chlorine. The
multiple antibiotic resistances were common amongst isolated bacterial strains.
Introduction: Urinary tract infections are very common in childhood (especially under the age of 5 years) and because of the large number of complications resulting from it (renal failure – hypertension- kidney scarring) had to be diagnosed and early
treatment, although that urine culture is the standard Golden diagnosis, but its results are late to appear, Many studies have indicated an accompanying increase in platelet counts in urinary tract infections, so that platelet counts may be a vital indicator directed to it without asylum to the costly analyzes in its diagnosis. Objective: the objective of the following study is to assess the sensitivity and specificity of the plate count (PLT) in UTI. Methods: The study included 65 Patients (14 males, 51females) They were between (3-6) year with upper urine tract infections were diagnosed through symptoms, urological test, Serum tests, and radiology, who were admitted to the pediatric department at Tishreen University Hospital in Lattakia City. PLT was obtained through a complete CBC blood count (sensitivity and sensitization), and comparison of the ratio Percentage of Thrombocytosis between urine culture with Gram-positive germs and Gram-negative germs. Results: The study showed a good sensitivity=80.39% [75–84] to platelet counts compared to urine culture. it also showed statistically significant paper p-value=0.003 between platelet count and type of pathogen (positive or negative Gram) and the increase was more favorable to positive urine culture. Also showed that the average value of platelets is higher in culture a positive gram 521.9±90.9 x103 platelet/mcl than in gram negative 432.3±73.5 x103 platelet/mcl. Conclusion: higher Platelet numbers are a good analysis or sensitivity for the diagnosis of upper urinary tract infection in children with reliable urinary symptoms to start treatment. So that we get the results of culture urine .and the higher platelet count must be taken gram positive bacteria into account.
