ABSTRACT

OBJECTIVES: This study aimed to discuss the different challenges faced while managing emergency vascular surgery cases during the COVID-19 pandemic and how these challenges were overcome. METHODS: This study details 14 emergency cases that were managed during a period of one month from mid-March to mid-April at Sultan Qaboos University Hospital, Muscat, Oman. The cases included acute limb ischaemia, critical limb ischaemia, type B dissection of the thoracic aorta, thoraco-abdominal aneurysm, critical internal carotid artery stenosis, trauma, infected arteriovenous forearm loop graft and thrombosed arteriovenous fistulas. RESULTS: Only one patient was confirmed to have COVID-19. Five were negative for COVID-19 while the remaining eight were not tested. Various strategies on how the vascular surgical team accommodated changes in hospital protocols and nationwide lockdown are discussed in detail. CONCLUSIONS: With the judicious use of personal protective equipment and consumable surgical and endovascular devices, communication with support services and other hospitals and implementation of triage protocols, it was possible to manage vascular surgery emergencies effectively.

ABSTRACT

Blunt thoracic aortic injuries are potentially lethal. Those who survive may form an organised haematoma in the periadventitial space resulting in a pseudoaneurysm, which may be identified incidentally decades later. While the role of thoracic endovascular aortic repair (TEVAR) in acute settings has been established, its role in chronic cases is yet to be defined. We report three cases that were diagnosed incidentally six, nine and 18 years after the injury. Two were managed by TEVAR while the third declined intervention and is on annual follow-up. Patients with asymptomatic and stable pseudoaneurysms of the descending thoracic aorta should be offered surveillance versus TEVAR because the risk of rupture is not negligible, whilst taking into account the patient's level of physical activity. These three cases highlight the importance of early diagnosis of aortic injuries in blunt trauma and its grading.

ABSTRACT

Clear cell hidradenoma (CCH) is a tumour originating from the eccrine sweat glands. It usually presents in the limbs, axilla or trunk. CCH of the breast is rare and can present as a cystic lesion in the breast that can be easily misdiagnosed as malignancy. We report a 36-year-old female patient who presented at the Sultan Qaboos University Hospital Breast Clinic, Muscat, Oman, in 2018 with a lump in her left breast. Ultrasound examination reported a complex cystic lesion with a solid, vascular component. An ultrasound-guided core needle biopsy was suggestive of clear cell hidradenoma. Surgical excision was performed and histopathology confirmed the diagnosis of CCH of the breast. This is the first ever case of a diagnosis of CCH made using core needle biopsy. CCH can be challenging to diagnose; therefore, awareness of its histopathological and ultrasonographic features are essential to avoid misdiagnosis and over treatment.

ABSTRACT

BACKGROUND: Road traffic accidents are known to be the main cause of traumatic brain injury (TBI). TBI is also a leading cause of death and disability. This study, by means of the idiographic approach (single-case experimental designs using multiple-baseline designs), has examined whether methylphenidate (MPH - trade name Ritalin) had a differential effect on cognitive measures among patients with TBI with the sequel of acute and chronic post-concussion syndromes. The effect on gender was also explored. METHODS: In comparison with healthy controls, patients with TBI (acute and chronic) and accompanying mild cognitive impairment (MCI) were screened for their integrity of executive functioning. Twenty-four patients exhibiting executive dysfunction (ED) were then instituted with the pharmacological intervention methylphenidate (MPH). The methylphenidate was administered using an uncontrolled, open label design. RESULTS: The administration of methylphenidate impacted ED in the TBI group but had no effect on mood. Attenuation of ED was more apparent in the chronic phases of TBI. The effect on gender was not statistically significant with regard to the observed changes. CONCLUSIONS: To our knowledge, this is the first feasibility trial from the Arabian Gulf to report the performance of a TBI population with mild cognitive impairment according to the IQCODE Arabic version. This investigation confirms anecdotal observations of methylphenidate having the potential to attenuate cognitive impairment; particularly those functions that are critically involved in the integrity of executive functioning. The present feasibility trial should be followed by nomothetic studies such as those that adhere to the protocol of the randomized controlled trial. This evidence-based research is the foundation for intervention and future resource allocation by policy- or public health decision-makers.

ABSTRACT

BACKGROUND: In Oman, anecdotal and impressionistic observation have helped parse and categorize various manifestations of spirit possession into two broad and distinct categories: intermittent dissociative phenomenon and transitory dissociative phenomenon. The primary aim of the present study was to compare the performance of participants on neuropsychological tests among different grades of possession. Other correlates were also sought. METHODS: Assessment criteria for the two groups included measures examining executive functioning: controlled oral word association test Verbal Fluency, Wisconsin Card Sorting Test (Perseverative error and the number of categories achieved), Trail Making Test and the Tower of London Test (number of correctly solved problems). Sociodemographic variables and the history of trauma were also sought. RESULT: Among 84 participants, one third of them presented the intermittent possession type and two thirds, the transitory possession type. Their mean age was 34.17 ± 11.82 and 56% of them were female. Nearly 35% of them endorsed a history of a traumatic experience. Both the multivariate models showed statistical significance (F (5, 78) = 5.57, p < 0.001, R2 = 0.22), F (5, 78) = 11.38, p < 0.001, R2 = 0.39) with an independent predictor of intermittent dissociative phenomenon (ß = - 3.408, p < 0.001), (ß = 63.88, p < 0.001) for Verbal Fluency and Trail Making Test, respectively. The history of the traumatic event was also statistically significant with the results of the Trail Making Test (ß = - 26.01, p < 0.041. Furthermore, the subtype of Pathogenic Possession turned out to be an independent predictor across all models: Wisconsin Card Sorting Test perseverative error, Wisconsin card sorting test categories achieved and the number of problems solved in the Tower of London Test (OR = 3.70, 95% C.I. 2.97-4.61; p < 0.001), (OR = 0.57, 95% C.I.0.39-0.84; p = 0.004) and (OR = 0.80, 95% C.I. 0.65-0.99; p < 0.037) respectively. CONCLUSIONS: This study suggests that typology of spirit possession found in Oman tends to differ on indices of executive function. Those with 'diagnosis' of intermittent possession showed impairment in many indices of executive functioning. Despite its wide prevalence, spirit possession has not been examined in terms of its neuropsychological functioning. We believe that this study will be instrumental in laying the groundwork for a more robust methodology.

ABSTRACT

BACKGROUND: Antimicrobial resistance is increasingly recognized as a global challenge. A few studies have emerged on epidemiology of multidrug resistant organisms in tertiary care settings in the Arabian Gulf. AIM: To describe the epidemiology of multi-drug resistant organisms (MDRO) at Sultan Qaboos University Hospital, a tertiary hospital in Oman. METHODS: A retrospective review of MDRO records has been conducted throughout the period from January 2012 till December 2012. Organisms were identified and tested by an automated identification and susceptibility system, and the antibiotic susceptibility testing was confirmed by the disk diffusion method. RESULTS: Out of the total of 29,245 admissions, there have been 315 patients registered as MDRO patients giving an overall prevalence rate of 10.8 (95% CI 9.3, 12.4) MDRO cases per 1000 admissions. In addition, the prevalence rate of MDRO isolates was 11.2 (95% CI 9.7, 12.9) per 1000 admissions. Overall, increasing trends in prevalence rates of MDRO patients and MDRO isolates were observed throughout the study period. CONCLUSION: Antimicrobial resistance is an emerging challenge in Oman. Continuous monitoring of antimicrobial susceptibility and strict adherence to infection prevention guidelines are essential to prevent proliferation of MDRO. Along such quest, stringent antibiotic prescription guidelines are needed in the country.

ABSTRACT

INTRODUCTION: There is a lack of studies examining the effectiveness of some of the commonly used instruments to elicit the presence of social anxiety disorder (SAD) in Arab-speaking populations, such as those in Oman. The aim of this study was to establish the influence of social anxiety and the role of gender among Omani adolescents. METHODS: A two-phase protocol was used, entailing the psychometric properties of the Arabic version of the Liebowitz Social Anxiety Scale (LSAS) against the gold standard, the Diagnostic and Statistical Manual of Mental Disorders (DSM). RESULTS: According to DSM and LSAS, the prevalence of social phobia among Omani students was generally higher compared to what has been reported in other parts of the world and the crosstabs analysis showed a significant correlation between gender and SAD. DISCUSSION: The Arabic version of LSAS proved to be an effective tool for assessing and quantifying the presence of SAD. This study discusses the sociocultural factors affecting social phobia in Omani society.
