Development of an ultrasound-guided technique for retrobulbar nerve block in dromedary camels: a cadaveric study.

OBJECTIVE: Description of an ultrasound (US)-guided technique for retrobulbar nerve blockade in dromedary (Camelus dromedarius) cadavers. STUDY DESIGN: Prospective experimental cadaveric study that was carried out in three phases: phase I: anatomical dissection and development of US-guided technique; phase II: methylene blue (MB) injection; phase III: contrast medium (CM), US-guided injections with computed tomography (CT) control. ANIMALS: A total of 36 orbits from 18 heads were obtained from 18 dromedary cadavers. METHODS: Phase I: anatomical dissections were carried out bilaterally, using two heads to determine needle site placement. Phase II: a US-guided, lateral, in-plane approach using one of three volumes of MB (3, 6, or 9 mL) was evaluated in six heads (four orbits per volume tested) to establish the ideal injection volume. Injections of MB that strongly stained all retrobulbar nerves were considered successful, whereas insufficient MB volumes resulted in weak or no nerve staining. Phase III: US-guided retrobulbar injection with CM was carried out using 20 orbits. Computed tomography was performed after each injection trial to determine the accuracy of needle placement and CM dispersal. An injection was judged to be successful when the CT images revealed that the needle was located within the retractor bulbi muscle cone and the CM reached the target nerves at the orbitorotundum and the optic foramina. RESULTS: Only injection of 9 mL of MB stained the target nerves sufficiently, whereas there was no or only weak staining with 3 and 6 mL, respectively. Therefore, 9 mL of CM was used for the US-guided injections in phase III. Subsequent CT scans revealed satisfying CM distribution within the ocular muscle cone in 18 of 20 cases (90% success rate). CONCLUSIONS AND CLINICAL RELEVANCE: US-guided retrobulbar injection in dromedary cadavers is feasible. Further research is required to assess its practicality and usefulness in vivo.

Reference values and repeatability of the Schirmer tear tests I and II in domesticated, clinically normal dromedary camels (Camelus dromedarius).

OBJECTIVE: To determine the normal values and repeatability for Schirmer tear test (STT) in clinically normal dromedary camels and to analyze the influence of the age and gender on these values. ANIMALS STUDIED: Thirty clinically normal dromedary camels of different ages (calves, immature, and mature). PROCEDURES: Schirmer tear tests I and II were performed using commercial STT strips. Three measurements were obtained from each eye over three consecutive weeks, and the variance of these measurements was determined. RESULTS: Mean values and coefficient of variation of STT I and STT II for the right and left eyes varied significantly among camel groups (P < 0.05). For STT I, the most frequently recorded values were >14-18, > 22-26, and >30-34 mm/min in calves, immature camels, and mature camels, respectively. For STT II, however, the most frequently recorded values were 7-14, >10-18, and >26-30 mm/min, respectively. The interassay coefficients of variation were 1.7-14.4% and were significantly lower in mature camels than in calves and immature camels (P < 0.05). Age was positively correlated with STT I (r = 0.81) and STT II values (r = 0.88). No significant variations were found between genders. CONCLUSIONS: This preliminary study reports STT I and II values and repeatability in normal dromedary camels. This information may assist veterinary practitioners in complete ophthalmic examinations and in accurate diagnosis of ocular surface diseases affecting the tear film in this species.

Egyptian Students Open to Digital Mental Health Care: Cross-Sectional Survey.

BACKGROUND: In Egypt, the shortage of mental health services, particularly for adolescents and young adults, is apparent. Electronic mental health (EMH) has been proposed as a solution to bridge the gap and better address the needs of young people. However, EMH is new to Egypt and its acceptability among target populations is crucial to its implementation and success. OBJECTIVE: The objective of this study is to explore the interest of Egyptian youth in EMH, identify perceived barriers to EMH, and inform the design of EMH tools to best address the needs of youth. METHODS: A web-based cross-sectional survey was distributed among medical students at Tanta University in Egypt. Chi-square and one-way analysis of variance tests were performed for inferential analyses using a significance level of .05. RESULTS: Of the 707 individuals who completed the survey (90.9% response rate), 60.5% (428) were female, 62% (438) lived in urban and suburban areas, and the mean age of the sample was 20.5 (SD 1.8) years. The vast majority of participants (522/707, 73.8%) had already used the internet to find information about mental health problems, but the information was unsatisfactory for about half of them (386/707, 54.6%). Almost all students reported that they would prefer web-based therapy if EMH were available through a trustworthy national web-based platform for youth mental health (601/707, 85%). Students believed that emotional difficulties, social support, and coping strategies were the main topics that EMH should help with. The most common perceived barriers for EMH use in Egypt were concerns about privacy (382/707, 54%) and a lack of technology literacy and unfamiliarity with EMH (352/707, 50%). CONCLUSIONS: EMH is a promising strategy for addressing gaps in the mental health care for young people. To construct and implement a digital system of care that addresses the unique needs and preferences of youth, adolescents and young adults should be involved in the co-development and design.

Mental health outcomes and help-seeking behaviours among Egyptian medical students: A cross-sectional study.

AIM: Approximately half of the population in Egypt is under the age of 25. Globally, mental illness represents the highest burden of disease in this age group. Yet in Egypt, there is still no youth-specific mental health system in place and the vast majority of young people do not have access to any professional mental health support. The objective of this study was to describe the mental health needs of Egyptian youth and the resources they use when seeking help. METHODS: An online cross-sectional survey was distributed among medical students at Tanta University in Egypt. Of the 707 individuals who completed the survey (90.9% response rate), 60.5% were female, 62.0% lived in urban and suburban areas, and the mean age of the sample was 20.5 (±1.8) years old. RESULTS: More than half (54%) of the students reported that they had been affected by mental health problems at some point in their lives. Anxiety and depression were the most common problems. Regarding help-seeking behaviours, participants mainly searched the web or spoke to peers and relatives; few reported approaching medical professionals. The majority of participants (59.7%) reported being disappointed with the current mental health care system in Egypt. CONCLUSIONS: There is a high prevalence of mental challenges among Egyptian youth and the health care system is not adequately prepared to respond to their needs. E-Mental Health and online interventions seem to be a promising solution that could increase access to mental health services for Egyptian youth.

Electronic Mental Health as an Option for Egyptian Psychiatry: Cross-Sectional Study.

BACKGROUND: Egypt is a country of nearly 100 million citizens, and there are less than 1000 registered psychiatrists. The mental health care system is under resourced and nearly inaccessible for the majority of the population. In addition, youth under the age of 25 years represent 50% of Egyptian citizens; however, there are no specific services addressing their unique needs. How can the needs of the largest population in the Middle East be effectively addressed? Is a web-based framework an option for Egyptian psychiatrists to serve the population? OBJECTIVE: The aims of this study were to better understand the opinions of psychiatrists on the current state of mental health care services in Egypt and their current knowledge on electronic mental health (EMH); assess the attitudes of Egyptian psychiatrists toward web-based interventions and telemedicine for mental health; and identify perceived advantages and barriers of EMH development in Egypt. METHODS: A cross-sectional survey was conducted online among 640 Egyptian psychiatrists. It included a total of 36 items within a set of 16 questions asking about EMH literacy, integrating EMH into the mental health care system, and the perceived priorities and barriers of EMH. The sampling was supported by Tanta University, a large academic institution close to Cairo. Statistical analysis was performed using SPSS 25 (IBM Corp). Descriptive statistics, the chi-square test, the independent sample t test, and analysis of variance were applied. RESULTS: A total of 188 participants responded (response rate of 29.4%), of which 54.2% (102/188) were female and 54.3% (102/188) were between 30 and 45 years old. Less than half of the participants thought that the current health care system was efficient for adults (69/155, 44.4%), and even less thought it was efficient for youth (44/155, 28.3%). Almost all participants agreed that EMH would be beneficial for patient care (147/155, 94.8%) and that integrating EMH into the current health care system would be a good idea (118/155, 76.2%). The highest rated utility of web-based solutions was documentation, followed by psychoeducation and communication with professionals. The main advantages were to improve access to care in rural areas of the country and its convenience. CONCLUSIONS: There is scarcity of mental health resources in Egypt. Egyptian psychiatrists are interested in EMH and believe web-based platforms can become part of the solution for the Egyptian mental health care system.

Computed tomographic arthrography of the normal dromedary camel carpus.

The aim of this prospective cadaveric study was to provide a detailed computed tomographic (CT) reference of the carpal joint in healthy dromedary camels. Twelve forelimbs of six apparently healthy camels were used. Computed tomographic imaging of 12 normal cadaveric camel carpal joints was performed before and after intra-articular administration of iodinated contrast medium. Transverse CT images were reconstructed in dorsal and parasagittal planes. The six carpal bones, the radial trochlea, and the proximal articular surface of the metacarpal bones were clearly visible on CT images with the bone setting window. Radiocarpal, carpometacarpal, transverse intercarpal, medial and lateral palmer intercarpal, middle intercarpal, accessory carpoulnar and medial and lateral collateral ligaments, carpal canal, joint capsule, and the extensor and flexor tendons were identified on CT images with the soft-tissue setting window. Postcontrast CT images provided better delineation of intercarpal ligaments, the capsular compartments and recesses. Results indicated that the osseous and the clinically important soft tissue structures of the dromedary camel carpal joint could be identified using CT and CT arthrography. The CT data of this study will serve as a basis for diagnosis of carpal problems in camels.

Electrophysiological and psychological studies in tinnitus.

OBJECTIVES: Tinnitus can be accompanied by depression, anxiety, insomnia, problems with auditory perception and poor general and mental health. This work was designed to evaluate the cognitive and psychological status in tinnitus patients using different subjective and objective measures. METHODS: This work included 40 patients complaining of tinnitus without any vestibular complaints. Those patients were compared with 40 healthy age and sex matched controls. All subjects were evaluated through: basic audiologic evaluation, electrophysiological test (P300), oculomotor tests (smooth-pursuit, optokinetic, gaze and saccadic eye movements) and psychological evaluation (Hamilton depression and anxiety scales, Mini Mental Status Examination and Trail making tests). RESULTS: Patients with tinnitus showed abnormalities at both electrophysiological and psychological levels when compared with normal subjects. CONCLUSION: This study provides evidences that different pathological mechanisms are involved in tinnitus generation which are more extensive than we thought.
