Role of sagittal - oblique technique of MRI in diagnosis of anterior cruciate ligament injuries
Authors: Hafez Abeer Abdel Maqsoud , khaliq Yasser Ibrahim Abdel , Mohamed Marwa Mohamed Abdel Zaher 
Published: October 2021

Abstract

Background
Sagittal-oblique technique clearly shows partial rupture because its’ double angulation follows the specific course of the patient’s ligament, due to approximate orientation of the external rotation of the foot. Sagittal-oblique technique provides a higher number of slices presenting the whole course of ACL

Objective
To value the role of sagittal- oblique technique of MRI adding to the standardized MRI technique in the diagnosis of anterior cruciate ligament injuries.

Patients and Methods
The study was approved by the hospital ethical committee and all patients agreed to participate in the study. We prospectively evaluated 20 patients with MRI examination of the knee. Patients presented with painful knee joint due to trauma of knee soft tissue structures. They were 9 females and 11 males, ranging in age from 26 to 67 years. Mean age is 39.80 years.

Results
Accuracy of standard MRI protocol of the knee comparing to additional technique is identical in detection of a complete ACL rupture. Presentations of the partial ruptures of ACL using sagittal-oblique technique were more sensitive than presentation using standard MR protocol. There was statistically significant difference between MRI detection of the ruptured ACL between additional techniques. Sagittal-oblique technique provides a higher number of MRI slices showing the whole course of the ACL and requires a shorter scan time.

Conclusion
The addition of oblique sagittal technique to the standard MRI imaging improved diagnostic accuracy for detecting partial tear of the ACL. However, oblique sagittal technique is just as precise as the standard MR technique for the evaluation of a complete rupture of the ACL, so it should be used in cases of suspicion of partial rupture of the ACL

Published: October 2021

Abstract

Background
Rotator cuff tears are a common orthopedic problem, and often these tears are so-called partial tears of the rotator cuff. A partial tear of the rotator cuff is an area of damage or degeneration to the rotator cuff tendons, where the tear does not go all the way through the tendons

Objectives
The aim of the work assessment of rotator cuff partial tear treatment with ultrasound guided platelet rich plasma injection.

Patients and Methods
Single arm interventional study which was conducted in Ain shams university hospitals in the period between March 2020 and October 2020, 10 confirmed cases of rotator cuff partial tear diagnosed by MRI were included in this study. Their ages ranging from 25 to 70 years old.

Results
Our study showed statistically significant improvements in 10 patients in VAS pain score, constant shoulder score, PENN shoulder score and OXFORD shoulder score.

Conclusion
The ultrasound-guided PRP injection for rotator cuff partial thickness tears is a safe, cheap, and easily prepared outpatient procedure which showed competitive, promising and wellproved results. PRP has the potential to heal the muscle-tendon unit of the rotator cuff and may be a primary nonsurgical treatment modality for rotator cuff tears.

Abstract

Background
Pulmonary involvement is the most common extra-articular manifestation of Rheumatoid arthritis.

Aim of the Work
To highlight the role of HRCT in detection and characterization of variable pulmonary manifestations that can be encountered in patients with Rheumatoid Arthritis trying to correlate the CT pulmonary manifestations with pulmonary functions using CT scoring system.

Patients and Methods
This was a retrospective study that included 32 patients who were diagnosed to have Rheumatoid Arthritis either outpatients or referred from the Rheumatology Department at Ain Shams University Hospitals to the Radiodiagnosis Department for HRCT chest examination. An acceptance from the ethical committee of Faculty of Medicine - Ain Shams University was obtained to use the data stored on PACs system with the patient’s consent was waived being a retrospective study. All patients underwent HRCT image analysis regarding the CT features and CT score for disease severity. Also, all patients did spirometery for pulmonary function assessment.

Results
Analyzing the data showed a female sex predominance (90.6%). 87% of the patients were diagnosed to have RA for more than 2 years duration. The most common respiratory symptom was dyspnea and the restrictive pattern was the commonest PFT finding. Ground glass pattern was the most common 78.1% followed by reticular pattern which was seen in 68.8% of patients. PFT and HRCT showed a positive correlation regarding the severity.

Conclusion
HRCT is a modality of choice for detection of pulmonary manifestation of rheumatoid arthritis patients with CT scoring can be used to assess the severity of disease and degree of lung involvement which is correlated with pulmonary function test.

Authors: Abdelwahab Sameh Mohammed , Abdelrahman Hazem Ibrahim , Said Pola Ibrahim 
Published: October 2021

Abstract

Background
Hematologic diseases are a group of prevalent and clinically diverse diseases that can affect any organ system. Hematologic disorders frequently involve bone and associated tissues causing significant alterations in the bone marrow and may have relevant side effects on the skeleton. In order to evaluate findings in bone marrow on MR imaging, it is essential to understand the normal composition and distribution of bone marrow and the changes in marrow that occur with age, as well as the basis for the MR signals from marrow and the factors that affect those signals.

Aim of the Work
To describe the musculoskeletal MRI findings in patients with hematological diseases.

Patients and Methods
cross sectional study was conducted in Ain Shams University hospitals on patients confirmed with hematological disease undergoing musculoskeletal MRI.

Conclusion
Magnetic resonance imaging is very beneficial noninvasive modality to evaluate bone marrow and detecting marrow lesions due to its ability to provide information at the level of cellular and chemical composition. Knowing normal marrow components and composition and their variation, as well as of factors that affect MR signal intensity, is important for optimal interpretation of MR images. The signal intensity, morphology, and location of marrow findings on MRI can be used to provide accurate diagnoses and to guide treatment of the discussed hematological diseases.

Published: October 2021

Abstract

Objectives
to assess the role of Cone Beam CT (CBCT) in the postoperative cochlear implant (CI) imaging in determining details about the electrode position, insertion depth, angle and other fine anatomical details.

Methods
This retrospective study included 32 patients (34 ears) with post-CI CBCT imaging. All images were anonymized and reviewed by two experienced head and neck radiologists in consensus for the measurements of the implant insertion depth, facial canal (vertical part) diameter, wall thickness and distance between it and the electrode cable, then assessment of the quality of visualization of fine structures as the facial nerve canal, chorda tympani, separate electrode contacts and scalar position of electrodes were done using 4-point scale.

Results
The insertion angles for the electrodes were measured in all the ears with a mean ± SD = 430.24 ± 121.43, the facial canal diameters were measured in 97.1% (33 ears) with a mean ± SD = 1.54 ± 0.33, the facial wall thickness was measured in 79.4% (27 ears) with a mean ± SD = 0.62 ± 0.32, the facial canalelectrode cable distances were measured in 97.1% (33 ears) with a mean ± SD = 1.64 ± 0.50 and the chorda tympani was visualized in 88.2% (30 ears). Perfect visualization of the scalar position of electrodes were encountered in 76.5% (26 ears), separate electrode contacts in 20.6% (7 ears), facial canal in 35.3% (12 ears), facial canal wall in 26.5% (9 ears), and chorda tympani in 41.2% (14 ears).

Conclusion
CBCT is a valuable tool in the postoperative assessment of cochlear implants
CT-angiography and Doppler ultrasonography in the evaluation of carotid artery stenosis: a comparative study
Authors: Khalifa Sherif Mohamed , Mohamed Ahmed Moustafa , Salama Asmaa Magdy 
Published: October 2021

Abstract

Background and purpose
Management of carotid artery stenosis is primarily based on the degree of luminal narrowing. The aim of this study is to compare the results of carotid doppler ultrasound (US) and CT angiography (CTA) for grading of carotid stenosis and for plaque characterization in symptomatic patients.

Methods
This is a cross sectional study with a total number of 35 consecutive patients having 70 carotid arteries for comparison. Grading of carotid stenosis was based on the NASCET criteria for CTA and the carotid consensus panel criteria for US. Each investigator was blinded to the results of the other modality.

Results
The majority of patients were aged from 60 to 69 years with male to female ratio of 3:2. Males were more commonly affected than females. The most common presenting symptom was recent stroke. Risk factors included; diabetes mellites and hypertension. Atherosclerotic ischemic heart disease was a present association. The carotid bulb and proximal ICA were the most common location for carotid plaques. Kappa analysis with 95 % confidence intervals (CIs) was utilized to determine US – CTA agreement. Both modalities showed overall good agreement (kappa = 0.63) and the concordance was better for moderate and higher grades of stenosis than for non-significant stenosis. The disagreement did not exceed one grade difference in our study sample. There was also good agreement as regards plaque morphology, while CTA was more sensitive than US in the detection of calcifications and plaque ulceration.

Conclusion
Doppler ultrasound when performed by an experienced sonographer can be used as a reliable first line modality for carotid stenosis grading and to categorize patients as medical and potentially surgical cases. CTA can be used as a confirmatory method for patients with borderline stenosis, for presurgical planning and for patients with suspected stenosis of the intracerebral circulation.

Authors: Hamed Waleed Abd El Aaty , Mohammed Hend Mubarak , Helmy Ahmed Fouad , Mohamed Amr Alaa El-Din 
Published: October 2021

Abstract

Background
The prevalence of inflammatory bowels diseases (IBD) increases in societies adapting a Western life style. Thus, it appears that there is an inverse relation between the prevalence of IBD and H. Pylori infection.

Aim
To compare the prevalence of H. Pylori Ag in stool between Ulcerative colitis patients and a normal healthy Egyptian sample.

Patients and methods
The current study was conducted on 70 patients recruited from the IBD study group clinic in Tropical medicine department of Ain Shams University Hospitals .This study group was compared to historical Control samples of healthy Egyptian subjects who were retrieved from a previously conducted study (saad et al.,2008).

The enrolled patients fulfilled the inclusion and exclusion criteria and were divided to two groups
o Study group: All patients who were diagnosed with U.C. based on clinical history, laboratory and endoscopic finding according to ECCO 2017 guidelines (Sandro et al., 2017).
o Control group: Historical Control samples from healthy Egyptian subjects.
Both groups were compared according to basal epidemiologic data and H. pylori Ag in stool positivity, gastrointestinal symptoms, colonscopic and microscopic findings, mainstay treatment lines of U.C., biological therapy and criteria of disease activity .

Results
Most of the enrolled patients in the current study were aged between 20-39 years with 48.6% aging between 20-29 years old and 38.6% between 30-39 years.
While the majority of the cases were females (62.9%), only 11.4% of the included cases were smokers .
We found that of the 70 patients in the cases group with ulcerative colitis, only 34 (48.6%) had positive H. pylori versus 555 reported positive samples in control group (91.7%). So there was a high significant statistical difference between the 2 groups

Conclusion
There is a significant association between H. pylori infection and ulcerative colitis that supports a possible protective benefit of H. pylori infection against the development of U.C. but still further studies are needed

Authors: Habeeb Ann Wadie , Aziz Mansour Dina Ezzat Abdel , Abdelsalam Shaat Ashraf , Mohammed Nabil Radwa 
Published: October 2021

Abstract

Background
Tear meniscus is one of the most important indices for therapeutic evaluation in treatment for obstruction of the lacrimal drainage system, which can be assessed by slit lamp examination and fluorescein dye disappearance test as a semi quantitative measurement. Recently Anterior Segment Optical Coherence Tomography has enabled noninvasive and quantitative assessment of tear meniscus.

Objective
To evaluate if measurement of tear meniscus by anterior segment OCT(AS-OCT) is a reliable method of assessment of improvement after Dacryocystorhinostomy (DCR) compared to other known methods which include dye disappearance test and lacrimal passages irrigation.

Patients and Methods
A prospective interventional study that included 16 eyes from 15 patients with primary acquired nasolacrimal duct obstruction who received external Dacryocystorhinostomy (ex-DCR) from March 2019 till November 2019, were evaluated prospectively on their tear meniscus height (TMH), tear meniscus area (TMA), and tear meniscus volume (TMV) changes by AS-OCT. Measurements were performed before surgery and 3 months after surgery.

Results
The results showed a highly significant decrease in all tear meniscus parameters (TMH, TMA, TMV) after DCR in patients with primary acquired nasolacrimal duct obstruction (PANDO), we concluded that AS-OCT can evaluate TM noninvasively and quantitatively, therefore it can be used as a reliable method of assessment of improvement after DCR compared to other known methods which include dye disappearance test and lacrimal passages irrigation.

Conclusion
Perioperative TM changes after ex-DCR can be evaluated noninvasively and quantitatively with use of AS-OCT, therefore it can be used as a reliable method of assessment of improvement after DCR, compared to other known methods which include dye disappearance test and lacrimal passages irrigation.
