ABSTRACT
PURPOSE@#The purpose of this in vitro study was to evaluate the accuracy of digitally designed removable partial denture (RPD) frameworks, constructed by additive and subtractive methods castable resin patterns, using comparative 3D analysis. @*MATERIALS AND METHODS@#A Kennedy class III mod. 1 educational maxillary model was used in this study. The cast was scanned after modification, and a removable partial denture framework was digitally designed. Twelve frameworks were constructed. Two groups were defined: Group A: six frameworks were milled with castable resin, then casted by the lost wax technique into Co-Cr frameworks; Group B: six frameworks were printed with castable resin, then casted by the lost wax technique into Co-Cr frameworks. Comparative 3D analysis was used to measure the accuracy of the fabricated frameworks using Geomagic Control X software. Student's t-test was used for comparing data. P value ≤ .05 was considered statistically significant. @*RESULTS@#Regarding the accuracy of the occlusal rests, group A (milled) (0.1417 ± 0.0224) showed significantly higher accuracy than group B (printed) (0.02347 ± 0.0221). The same results were found regarding the 3D comparison of the overall accuracy, in which group A (0.1501 ± 0.0205) was significantly more accurate than group B (0.179 ± 0.0137). @*CONCLUSION@#In indirect fabrication techniques, subtractive manufacturing yields more accurate RPDs than additive manufacturing.
ABSTRACT
Background: Anemia is a common medical disorder affecting a lot of women in pregnancy in the developing countries. Anemia is the second indirect obstetric cause of death after cardiac causes
Aims: To compare the safety, tolerability, efficacy and hematological response of lactoferrin in treatment of iron deficiency anemia during pregnancy versus ferrous sulfate capsules
Methodology: Hematological Response to lactoferrin versus ferrous sulfate in Treatment of Anemia with Pregnancy". Study site: Ain Shams University hospital. Study design: A double blind clinical trial. Study population: The study was included Two-hundred pregnant females with iron deficiency anemia attending the outpatient clinics of Ain shams university maternity hospital for routine antenatal care. For each pregnant woman, age, parity and gestational history were taken before treatment. All pregnant women took their allocated treatment regularly for eight weeks after diagnosis of iron deficiency anemia with hemoglobin level and serum ferritin level and followed up after four and eight weeks. Also, epigastric pain, diarrhea, constipation, nausea, vomiting or gastric distress reported to assess tolerability of the drugs
Results: The study included 200 pregnant women in a double blind study: Group I [lactoferrin]: 100 cases were received 100mg of bovine lactoferrin [Pravotin sachets, Hygint, Egypt] twice a day. Group II [ferrous sulfate]: 100 cases were received 150 mg of dried ferrous sulphate + folic acid [vitamin B9] 0.50mg [Ferrofol, E.I.P.I.C.O, Egypt] three capsules per day
Conclusion: lactoferrin is more tolerable than ferrous sulphate. It has lesser GIT side effects and seems to icrease both hemoglobin and serum ferritin more than iron salts
Recommendations: Lactoferrin is recommended for patients with iron deficiency anemia

Background: gynecological laparoscopy is now becoming a more popular technique for diagnosis and treatment of infertility cases; however gynecological laparoscopy is usually followed by Post-operative pain which may be attributed to small incision in abdominal wall or as a result of diaphragmatic irritation by inflating gases
Aim of the Study: was to assess the role of local anesthesia instillation in pain relief after laparoscopy
Patients and methods: the present study was a randomized trial study performed on 146 women aged 20-35 years, admitted to Ain Shams University hospitals. Patients were split into 2 equal groups, Group[A]: further subdivided into A1 and A2 whom undergone diagnostic and operative laparoscopy respectively- patients administrated 20ml of 0.25% of Bupivacaine instilled intraperitoneal-and Group [B]: further subdivided into B1 and B2 -whom undergone diagnostic and operative laparoscopy respectively-Patients administrated 20ml of 0.75% of Ropivacaine instilled intra-peritoneal. Vital signs and Pain scores were measured preoperatively, immediate postoperative, 1 hours, 2 hours, 4 hours, 8 hours, 12 hours postoperatively. Data was collected, tabulated, then analyzed using IBM[copyright sign] SPSS[copyright sign] Statistics version 22 [IBM[copyright sign] Corp., Armonk, NY]
Results: administration of 20mL of Ropivacaine 0.75% at the end of technique gave pain relief for four hours in group B1 and pain relief for three hours in group B2, associated with an increase in heart rate and blood pressure for two hours in group B1 and B2 for three hours
Conclusion: instillation of local anesthetic after laparoscopy promotes pain relief post operatively and further minimizes the postoperative hospital stay
ABSTRACT
Objective: to determine the role of Multidetector computed tomography [MDCT] in diagnosis of small bowel neoplasms
Methods: from September 2010 till March 2013, small bowel neoplasms evaluated by MDCT in 17 patients [14 males and 3 females]
Results: The small bowel neoplasms found and included in this study were lymphoma [12 patients], malignant gastrointestinal stromal stromal tumor [GIST] [3 patients], primary duodenal adenocarcinoma [1 patient] and jejunal metastasis [1 patient]
Conclusion: MDCT can he used as a front-line imaging modality for detection of small bowel neoplasms, regarding its ability, to show intraluminal, mural and extraintestinal lesions with their characteristic density and features to successfully differentiate between the different neoplasms and stage them
