Background Most individuals are infected by Helicobacter pylori during early childhood; in developing countries, 50% of children are infected by the age of 5 years. Successful eradication is important to prevent the development of antibiotic resistance, as well as to reduce the number of treatments and procedures. Among children receiving the standard triple therapy regimen, eradication rates are declining. Thus, national/ regional antibiotic resistance data could be used to guide treatment regimens for H pylori infection Aim of the work to evaluate the antibiotic resistance patterns of Helicobacter pylori strains among pediatric patients and the predictors of this resistance. Patients and Methods Cross sectional, carried out on 30 pediatric patients who presented to gastroenterology unit Ain Shams University for endoscopic evaluation of their upper GI symptoms including hematemesis, vomiting and abdominal pain. Five gastric biopsies were taken, two from the corpus for histopathology and culture, and 3 from the antrum, where one of them was sent for histopathology, and the second one for rapid urease test, and the third one was sent for culture and sensitivity. Results Results of culture and sensitivity has shown that resistance to amoxicillin was 20%, to clarithromycin was 50%, metronidazole resistance was 86.7%, tetracycline resistance showed to be 13.3%, finally levofloxacin resistance was 6.7%. Excess intake of fat was associated with resistance to amoxicillin and clarithromycin. While, duodenal ulcer and duodenal nodularity were associated with resistance to tetracycline and levofloxacin respectively. Conclusion The eradication regimen in Egypt should be revised according to our national antibiotic resistance data. Further studies are needed to assess predictors of resistance to antibiotics.

Background Flexor tendon injuries are a commonly occurring injury presenting to hand surgeons. Using PRP to augment tendon healing has been advocated only recently. Few studies discussed the effect of injection of PRP in tendon healing after tendon repair in large joints as regard functional outcome and range of motion (e.g. Achilles tendon and rotator cuff) Objective To study the effect of combination of PRP injection with physiotherapy on gliding and range of motion improvement after zone II flexor tendon repair. Patients and Methods prospective interventional controlled clinical study preformed on 40 patients with zone II flexor tendon injury. Patients were divided into two groups, group I (interventional group) PRP was injected around the tendon at the site of repair after one and six weeks of repair and patients received physiotherapy according to our unit protocol. In group II (control group) patients received physiotherapy only. Both groups were evaluated at six and twelve weeks regarding the range of motion according to Buck-Gramko II criteria. Results Based on the Buck-Gramcko II criteria, the overall results ranged between fair and good in both groups after six weeks of repair, the score ranged between 7-16 (mean= 11.5) in group I and 6-14 (mean= 10) in group II, There was no statistical difference between the two groups (P = 0.46).After 12 weeks of repair, the overall results ranged between good and excellent in both groups, the score ranged between 11-17 (mean= 14) in group I and 9-16 (mean=12.5) in group II. There was no statistical difference between the two groups (p = 0.207). Conclusion PRP injection had no statistical significant effect of on the gliding after flexor tendon repair at zone II.
