Authors: Mabrouk Amr A , Alliethy Iman M , Al Mahmoudy Niveen F , El-sayed Yara S 
Published: October 2021

Abstract

Background
Oro-facial clefts include a range of congenital deformities most commonly presenting as cleft lip with or without cleft palate (CLP) or isolated cleft palate (CP). CLP is the second most common congenital birth defect in the U.S.

Aim of the Work
to assess modified v-advancement vermilion flap combined with Tennison technique for vermilion repair in unilateral cleft lip regarding aesthetic outcome in comparison with repair of cleft lip by Tennison technique.

Patients and methods
This study was conducted in plastic, maxillofacial and reconstructive surgery department in Ain Shams University between September 2019 to February 2020. It included 20 patients divided into two group; the first group consisted of 10 patients who underwent repair of cleft lip by Tennison technique and the second group consisted of 10 patients who underwent repair by Tennison technique combined with v- advancement vermilion flap. Both groups were assessed postoperatively by Asher-McDade et. al. scoring system.

Result
The study showed statistically significant difference between the two groups as regard the white lip length which was more symmetrical in cases repaired by Tennison technique combined with modified v-advancement vermillion flap (P = 0.01). The bulge and the deficiency in the lateral vermilion were decreased in the group treated by Tennison technique with modified v-advancement vermilion flap. However the difference was statistically insignificant (P = 0.66).

Conclusion
The choice of a technique for surgical correction of UCL should be based on an evidence that this technique has the best functional and aesthetic outcomes. The findings of this study support the view that these two methods of cleft lip repair have their own advantages and disadvantages. Tennison technique combined with vadvancement vermilion flap achieved less bulge in the vermilion with no statistically significant difference.

Published: October 2021

Abstract

Background
Magnetic resonance is the best imaging modality to assess hip joint in non-traumatic cases. It has a great ability to diagnose disorders of bone, cartilage, ligaments, muscles and soft tissue. MRI can also detect joint effusion and bone marrow edema. Aim of the Work: To assess the value of MRI as the imaging modality in children presenting with acute non-traumatic hip pain and its ability to assess the cause of the pain early without the use of another imaging modality.

Patients and Methods
A retrospective study was conducted on pediatric patients with non-traumatic hip pain, referred from the outpatient pediatric clinic, orthopedic clinic, Ain Shams University hospitals. The patients were investigated using magnetic resonance imaging (MRI) for detection the cause of non-traumatic hip pain.

Results
In this study we found that avascular necrosis is the commonest cause of non-traumatic hip pain followed by isolated hip effusion then synovitis. Other causes included perthes, septic arthritis, osteomyelitis, aneurysmal bone cyst, SCFE, PFFD and Osteomalacia. Magnetic resonance imaging doesn’t only demonstrate disorders of hip joint only; it also gives an accurate assessment of other extra-articular causes of referred hip pain.

Conclusion
Hip MRI is a practical, well accepted and accurate non-invasive imaging technique in children presenting with acute non-traumatic hip pain.

Published: October 2021

Abstract
Background: The AT is the largest tendon in the body; it plays an important role in the biomechanics of the lower extremity; despite its strength, the AT is also vulnerable to injury, due to its limited blood supply from musculotendinousa, also it withstands great forces, especially during sporting exercises and it's located superficially.
Aim of the Work: To evaluate the role of (MRI) in the diagnosis of AT disorders.
Patients and Methods:
Type of Study: retrospective and prospective studies.

Study Setting
The study was conducted in Radiology Department at Ain Shams University Hospitals.

Study Period
from march 2018 to march 2020.

Study Population
This study included 40 patients. The patients were referred from either the orthopedic, rheumatology outpatient clinics of Ain Shams hospitals or private clinics to radiology department in Ain Shams University.

Results
Full thickness tear (30.0%) and Tendenosis (30.0%) were the most frequently detected pathologies followed by partial thickness tear (27.5%) and bursitis ( 22.5%) with significant more risk in male gender and middle age ( &gt;46 years). More than one pathology were found in the same MRI study and this led to development of degenerative theory, that consider almost ruptured AT develop on top of pathological one.

Conclusion
MRI is a gold standard and important diagnostic tool in the evaluation of AT lesions especially in chronic and complex cases, and who do not respond to conservative measures and provides precious information for surgical intervention in parallel with careful clinical examination. Full thickness tear and partial thickness tear may develop on top of pathological tendon.

Authors: Abdelraouf Maha Mohamed , Ahmed Amal Ibrahim , Elghitany Nouran Abdelrahman 
Published: October 2021

Abstract

Background
Carpal tunnel syndrome (CTS) is the most common nerve entrapment syndrome. It is caused by compression of the median nerve as it passes through the carpal tunnel in the wrist. The diagnosis of CTS is based on a combination of characteristic symptoms and electrophysiologic abnormalities. Electrodiagnostic testing (EDT) is uncomfortable for patients, time consuming and expensive.

Objective
To evaluate the role of greyscale and strain elastography ultrasound imaging in diagnosing patients with CTS and controls in comparison with nerve conductive studies.

Patients and Methods
Type of Study: Descriptive, prospective study. Study Setting: The study will be conducted at Ain Shams University Hospitals, Radiodiagnosis department. Study Period: 6 months. Study Population: Patients with carpal tunnel syndrome diagnosed clinically and underwent nerve conduction velocity study.

Results
In this study 7 wrists were diagnosed with mild CTS, 5 wrists demonstrated moderate CT, whereas only 3 wrists revealed severe CTS. The mean CSA would have increased if the number of cases with severe CTS had been higher. CSA of the median nerve has been reported to increase with the severity of entrapment. The cut off point of the average CSA to differentiate between cases and controls was found &gt; 8 with sensitivity of 93.33%, specificity of 80% and area under curve (AUC) of 91.3% while the best cut off point for Elasto score was found &gt; 1 with sensitivity of 86.6%, specificity of 80% and area under curve (AUC) of 93.3%.

Conclusion
We concluded that sonoelastography is a sensitive tool for prediction of CTS and it’s severity in correlation to NCV.

Authors: Elia Remon Zaher , Hassan Hend Galal Eldeen Mohamed Ali , Samuel Remon Nader Nathan 
Published: October 2021

Abstract

Background
Pulmonary embolism (PE) is a common condition with considerable morbidity and mortality; it is more often diagnosed post-mortem by pathologists than in vivo by clinicians. Prompt and accurate diagnosis is difficult because PE may be clinically silent, the symptoms are vague and nonspecific, and in addition there is no definitive, non-invasive diagnostic test to establish its diagnosis.

Objectives
The aim of this study is to discuss the reliability and clinical effectiveness of the incidental detection of a PE on non-contrast CT which could be advantageous in the emergent context and also in patients with pre-existing renal disease or known allergies to contrast agents in a situation without viable alternative.

Patients and Methods

Results
In our study CTA was used as the method of choice in detection of central pulmonary embolism in highly suspected pulmonary embolism in twenty patients and we compared it with pre contrast scan to identify non contrast CT reliability in detection of central pulmonary embolism. Our study showed that non contrast CT chest have a good role in detection of central pulmonary embolism as hyper dense lumen sign.

Conclusion
Unenhanced MDCT is an alternative approach for the diagnosis of acute central PE when CTPA is inaccessible or contraindicated. In our study Non-contrast chest CT scans have good role in evaluation of PE through detection the hyper dense lumen sign that is a good indicator of acute pulmonary thromboembolism particularly in cases involving the central pulmonary arteries.

Published: October 2021

Abstract

Background
Breast cancer is a major health problem in women and early detection is of prime importance.

Objective
We aimed to evaluate the role of diffusion-weighted imaging with background body signal suppression (DWIBS) in detection of breast lesions and characterization of these detected lesions.

Patients and methods
40 female patients with suspicious 50 breast lesions detected by sonomammography, in addition to the routine protocol that includes T1Wi's, T2Wi's, STIR, DCE-MRI and DWI sequences (with ADC maps) all participants underwent DWIBS sequence (with ADC maps). The histopathology served as reference standard. First, we compared the detectability of breast lesions on DWIBS with that of the DWI. We then compared the ADCs of the malignant lesions (n = 35) to that of the benign lesions (n = 15) in both DWI and DWIBS.

Results
Thirty seven lesions were detected via DWIBS (detectability of 74.0%) which was less than that of DWI (detectability of 78.0%). In DWIBS, the mean ADC value of the malignant lesions (0.80 ± 0.27 × 10-3mm2/s) was significantly lower than that of the benign lesions (1.40 ± 0.41 × 10-3mm2/s). With a cut-off value of 1.3 × 10-3mm2/s for ADC, DWIBS achieved 85.7% sensitivity and 80% specificity for differentiating between benign and malignant lesions.

Conclusion
Although it showed lower detectability for breast lesions than DWI, our study suggests that DWIBS is superior to DWI in the characterization of malignant breast lesions.. Also based on ADC, DWIBS provides additional information that may further increase the specificity of breast lesion characterization.

Authors: Abdelhafiz Zeinab Yousif Ishag , Ali Khalid Ahmed Mohammed , Badraldeen Safaa Kamal Mohammed 
Published: October 2021

Abstract

Background
Sonography is a useful imaging tool for the examination of musculoskeletal pathology. There are many advantages to this technique, including easy accessibility, low cost, comparison with the asymptomatic limb, and patient comfort. Unlike other available modalities, dynamic assessment is readily performed using sonography. Furthermore, the use of Doppler technique allows assessment of vascularity, inflammation, and anatomical relationships of the structure in question to adjacent vessels.

Aim of Study
This study investigates the value of dynamic ultrasound in the evaluation of AC and SC joints abnormality in comparison with the asymptomatic limb.

Patients & Methods
This prospective study included fifty cases, thirty patients were clinically positive for shoulder pain. Twenty healthy persons examined as control group. The patients were referred from Rheumatology and Immunology Department of Ain Shams University.US evaluation was performed at the Radiology Department of Ain –Shams University Hospital in period from January to June2018, to characterizing the AC and SC joints, their pathogenesis and sequelae. Dynamic US examination was also performed in all the cases.

Results
This study included 30 patients. The most common presenting symptoms in the primary care were shoulder pain which present in all 30 patients. Appropriate history and physical examination coupled with correct radiographs usually lead to an accurate diagnosis, we add that dynamic US which served a role in directing the management plan in 18 patients, this further confirmed with a positive clinical examination, in contrast to the other 12 patients for whom there was negative clinical findings.

Conclusion
High-resolution US technology, coupled with good anatomical knowledge and proper technique, has become valuable in the assessment of ACJ pathology as can be a useful initial diagnostic modality in SCJ osteoarthritis. Using US as a first line investigative tool can eliminate the need for further more expensive investigation like CT/ MRI and serve as a guide for further imaging and management.

Published: October 2021

Abstract

Background
Infection with hepatitis C virus (HCV) is a major cause of chronic hepatitis, cirrhosis and hepatocellular carcinoma worldwide. Liver disease is not the only problem caused by chronic HCV infection; many extra-hepatic complications such as insulin resistance (IR) can be associated with HCV infection as well.

Objective
To assess the effect of sustained virological response on insulin resistance in patients with chronic hepatitis C infection.

Patients and methods
This study was conducted in New Cairo Viral Hepatitis Treatment Center (NCVHTC), in the period between December 2017 and December 2018. The current study was conducted on 46 enrolled HCV patients with type 2 Diabetes Mellitus (T2DM). Fasting Insulin (FI) and fasting blood glucose (FBG) as well as lipid profile were assessed in all patients at three time points; before treatment, at the end of treatment (EOT) and 12 weeks after the EOT.

Results
Despite using 4 different DAA regimens, all patients achieved SVR regardless of the regimen used. As a measurement of IR, HOMA-IR was calculated at the three time points using FI & FBG, it was found that HOMA-IR decreased significantly at the EOT; however, when calculated at week 12 after EOT, the reduction of HOMA-IR was not significant compared to the baseline levels. on the other hand, total cholesterol & LDL increased at the EOT and continued to increase at 12 weeks after the EOT.

Conclusion
Improvements in IR and glycemic control were not statistically significant after achieving sustained virologic response (SVR) with DAAs in patients with chronic HCV infection. Changes in the lipid profile such as an increase in the levels of total cholesterol and LDL can be expected after treatment with DAAs.

Published: October 2021

Abstract

Background
Pedicle screw instrumentation has gained wide popularity for stabilization of spinal fusions. The use of pedicle screw fixation has increased fusion rates. The placement of segmental pedicle screws and cross-links in short segment posterior pedicle screw constructs has been shown to increase the construct stiffness in some planes.

Aim of the Work
to evaluate addition of crosslinks to posterior pedicular screw fixation as a modality for surgical management of lumbar spondylolisthesis.

Patients and Methods
This study included 50 patients with lumbar spondylolisthesis divided into two groups according to the surgical approach used in treatment. One group with Posterolateral fixation by transpedicular screws and rods and the other Group had cross-links added to the posterior construct.

Results
There was no significant difference in postoperative JOA score between both groups, while comparing mean of preoperative and postoperative JOA scores in each group showed a significant rise of the score in each group after surgery. There was no significant difference in the variables of postoperative sagittal alignment between both groups, while comparing mean of preoperative and postoperative sagittal alignment variables in each group revealed a significant reduction of the disc height percent in both groups, and in slip angle and lumbar lordosis angle in group B. Regarding postoperative rate and degree of improvement in the studied groups, there was no significant difference in the rate and degree of improvement between both groups.

Conclusion
no appreciable benefit from using cross-links was found in short-segment fixation of lumbar spondylolisthesis, where there’s no or little torsional instability encountered.
