Off-pump coronary bypass grafting with or without the use of intracoronary shunts

Background: There is scarce literature comparing the role of the intracoronary shunt during off-pump coronary artery bypass grafting (CABG). This study aimed to compare off-pump CABG using intracoronary shunt versus the coronary clamp during distal coronary artery anastomosis. Methods: We conducted this randomized study between January and June 2018. We randomized 30 patients into two groups. Group A (n= 15) included patients who had coronary clamping during off-pump CABG, and Group B (n= 15) included patients who had intracoronary shunt during off-pump CABG. Study endpoints were anastomosis time and postoperative cardiac enzyme levels. Results: The mean age of the shunt group was higher than the mean age of the clamp group (61.06 ± 7.26 vs. 56.72 ± 12.44, respectively, p=0.03). Our study showed no statistical difference between the two groups regarding sex (p˃0.99), hypertension (p˃0.99), and diabetes (p=0.14). The distal anastomosis time was longer in the shunt group than in the clamp group (39.80±4.55 vs. 32.27±6.06 minutes, respectively, p=0.001). The postoperative troponin I (0.61±0.11 vs. 0.26±0.089 ƞg/ml, p<0.001), and CK-MB levels (44.27±5.34 vs. 35.5±4.86 IU/L, p<0.001) were significantly higher in the clamp group. Conclusion: The intracoronary shunt could be associated with lower cardiac enzyme release compared to the clamp technique. However, it was associated with a longer distal anastomosis time

Evaluation of upper 1st molar rotation during maxillary canine retraction in 1st premolar extraction cases at 6 weeks reactivation interval. A clinical trial.

Abstract: Purpose: the aim of this clinical trial is to investigate maxillary first molar rotation during maxillary canine retraction at 6 weeks re-activation intervals with elastic power chain in first premolar extraction cases. Material and methods: a total of 20 quadrants of 10 orthodontic patients requiring maxillary canine retraction after extraction of upper 1st premolars were recruited. Mini-screws (TADs) were used directly for maximum anchorage. Canines were retracted on 0.016×0.022-inch stainless steel arch wire using elastic power chain extending from a power arm on canine bracket to the miniscrew. Cone beam computed tomography (CBCT) was used to measure the upper first molar rotation. Results: The mean difference of the first molar rotation between pre-retraction and post-retraction measurements was 0.6250o ± 0.6o which was statistically insignificant. Conclusion: There is no significant difference between pre-retraction and post-retraction upper first molar rotation re-activated every 6 weeks using power chain

Predictive Value of Alvarado Score and Ultrasound in the Diagnosis of Acute Appendicitis (A prospective study

Background:  Acute appendicitis is the commonest non traumatic cause of acute abdominal pain that needs surgical management .Alvarado score and ultrasonographies are the most cost effective, easy and available aids for diagnosis. The aim of the study was determining   the reliability of Alvarado score and ultrasound in the diagnosis of acute appendicitis. Results: The study was applied with 100 cases with different types of abdominal pain at presentation with 51 males and 49 females .The sensitivity was97.3% ,specificity 90%, and accuracy  89 of combined usage of Alvarado score and U/S findings preoperatively. Patients and method:  A prospective non-interventional study including patients admitted with suggestive history with signs and symptoms of acute appendicitis to the surgical emergency ward of Baghdad teaching hospital from July 1st 2017 to Feb 10th 2018, Alvarado score calculated and ultrasonography done for each patient enrolled in this study, then to be followed for intraoperative findings. Conclusions: Combined application of Alvarado score and U/S has sensitivity 94.1% ,specificity 90% and accuracy 89% . In our medical facility and emergency ward, acute appendicitis remains as one of the top acute abdominal emergencies needing surgery in patients presenting with atypical clinical finding. So diagnosis becomes difficult. So Alvarado score along with ultrasound findings are useful for increasing the reliability in emergency department for  accurate diagnosis of acute appendicitis therefore there should be training for the use of U/S by emergency physician and general surgeon in the diagnosis of acute appendicitis in order to decrease the rate of negative appendectomies

Evaluating the Amount of Tooth Movement and Root Resorption during Canine Retraction with Friction versus Frictionless Mechanics Using Cone Beam Computed Tomography

BACKGROUND: The current study was carried out to compare the amount of tooth movement during canine retraction comparing two different retraction mechanics; friction mechanics represented by a NiTi closed coil spring versus frictionless mechanics represented by T - loop, and their effect on root resorption using Cone Beam Computed Tomography (CBCT).METHOD: Ten patients were selected in a split-mouth study design that had a malocclusion that necessitates the extraction of maxillary first premolars and retraction of maxillary canines. The right maxillary canines were retracted using T - loops fabricated from 0.017 X 0.025 TMA wires. The left maxillary canines received NiTi coil spring with 150 gm of retraction force. Pre retraction and post retraction Cone Beam Computed Tomography were taken to evaluate the amount of tooth movement and root resorption using three-dimensional planes.RESULTS: T - loop side showed statistically significant higher mean anteroposterior measurement than NiTi coil spring side, indicating a lower amount of canine movement pre and post a canine retraction. Concerning the root resorption, there was no statistically significant change in the mean measurements of canine root length post retraction.CONCLUSION: The NiTi coil spring side showed more distal movement more than the T-loop side. Both retraction mechanics with controlled retraction force, do not cause root resorption

Effecacy of Uterine Artery Embolization in the Management of Symptomatic Uterine Myomata

Abstract Objective: The aim of the our study is to evaluate the results of the uterine artery embolization (UAE) as a modality for the treatment of uterine fibroids as regard to improvement of symptoms and reduction of fibroid size, and pregnancy after uterine artery embolization. Design: Prospective clinical study. Methods: All patient subjected to history taking, general examination, routine labolatory evaluation, ultrasound evaluation. For all cases ultrasonography (abdominal and/or vaginal) was performed to measure the size of fibroid (s) before UAE. Then UAE using gel foam was performed occluding the feeding vessels for myomata. Evaluation of cases for reduction of tumour size and improvements of symptoms was performed one month, 3 months and 6 months after the procedure, long term follow-up of pregnancy occurrence. Main outcome measures: Duration of technique, reduction of tumour size, significant improvement of symptoms, complications, pregnancy occurrence. Results: The procedure was successful in 36 out of 40 cases (90%). Difficult or failed technique was encountered in four cases only. There was a significant reduction of tumour size and a non significant improvement of symptoms after one month. There were a significant and a highly significant improvement of symptoms after 3 and 6 months respectively and a highly significant reduction of tumour size at both 3 Correspondence to: Dr. Wael S. Nossair, The Department of Obstetrics & Gynecology, Faculty of Medicine, Zagazig University and 6 months. Subcutaneous hematoma, a small leak of contrast medium, fever with or without offensive vaginal discharge and pelvic pain were the complications noticed during or after UAE. Pregnancy occurred in 22/40 (55%) patients (some virgin patient married and got pregnancy) during long term flow-up. The fate of pregnancy was 2 abortions, 3 preterm labour, 1 IUFD, 16 term pregnancies. Conclusions: UAE is an endovascular method for treatment of uterine fibroids that is clinically effective in most patients reducing the tumour size. It is invasive but relatively safe technique. Pregy can occur with long term follow-up

Effect of Low Level Laser Therapy on Gingival Inflammation in Patients undergoing Fixed Orthodontic Treatment: A Randomized Clinical Trial

AIM: The aim of this study was to compare the effect of low level laser therapy (LLLT) with non-LLLT as an adjunct to mechanical debridement in patients who develop gingival inflammation during fixed orthodontic treatment. MATERIALS AND METHODS: Thirty subjects undergoing comprehensive fixed orthodontic treatment were randomly allocated. Split mouth design was applied for each patient, where the four quadrants were randomly allocated to receive full mouth debridement. The test group (quadrant) received three laser sessions (days 1, 3, and 5) besides debridement while the control group (quadrant) received debridement only. Both bleeding index (BI) and plaque index (PI) were measured after 1 and 3 months, while the total colony forming units (CFU) were measured after 2 and 6 weeks. RESULTS: Clinical assessments (BI and PI) showed a statistically significant decrease at the first follow-up (after 1 month) and a slight increase in the second (after 3 months) that did not reach the base line. While, the total CFU showed a significant decrease in both follow-ups. CONCLUSION: Laser showed superior results in the treatment of gingival inflammation induced by fixed orthodontic appliances other than debridement only

Adaptive Fuzzy Supplementary Controller for SSR Damping in a Series-Compensated DFIG-Based Wind Farm

Although using a series compensation technique in a long transmission line effectively increases the transmittable power; it may cause a sub-synchronous resonance (SSR) phenomenon. Gate-controlled series capacitor (GCSC) is an effective method for SSR damping by controlling the turn-off angle. In the previous studies, a constant supplementary damping controller (SDC) was used for controlling the turn-off angle, which can mitigate the SSR phenomenon. However, these methods can not capture the maximum transmittable power at different operating points. In this paper, a fuzzy logic controller (FLC) is proposed to compute the gain of SDC based on the wind speed and the error between the measured and reference line currents for transferring as much power as possible and damping the SSR phenomenon simultaneously. Using the MATLAB/SIMULINK program, the proposed method is tested at different operating points to validate its effectiveness and robustness. Compared to the traditional method (constant SDC), the maximum transmittable power, as well as SSR damping, is achieved in all studied cases by the proposed method (variable SDC)

Treatment of Acute Promyelocytic Leukemia with AIDA Based Regimen. Update of a Tunisian Single Center Study

In Tunisia, the ATRA era began in 1998 with the use, consecutively, of two regimens combining ATRA and an anthracycline with cytarabine (APL93), and without cytarabine (LPA99). From 2004, 51 patients with confirmed APL either by t(15;17) or PML/RARA were treated according to the PETHEMA LPA 99 trial. Forty three patients achieved CR (86%). The remaining seven patients had early death (one died before treatment onset): four caused by differentiation syndrome (DS) and three died from central nervous system hemorrhage. Multivariate analysis revealed that female gender (P=0.045), baseline WBC> 10 G/L (P=0.041) and serum creatinine > 1.4mg/dl (P=0.021) were predictive of mortality during induction. DS was observed in 16 patients (32%) after a median onset time of 15 days from treatment onset (range, 2–29). Body mass index ≥ 30 (P=0.01) remained independent predictor of DS. Occurrence of hypertensive peaks significantly predicted occurrence of DS (P=0.011) and was significantly associated with high BMI (p=0.003). With a median follow-up of 50 months, 5 year cumulative incidence of relapse, event free and overall survival were 4.7%, 74% and 78%, respectively
