Introduction Intracranial hemorrhage (ICH) is a potentially severe complication of spinal surgeries. The occurrence of such complications causes deterioration of the patient's clinical status and delayed discharge from the hospital. Although no specific etiological factors were identified for this complication, but multiple risk factors might play role in its development, they include the use of anticoagulants, presence of uncontrolled hypertension, and perioperative patient positioning. Aim A systematic review of the literature to investigate the prevalence of different types of intracranial hemorrhages in patients who underwent spinal surgeries. Methods A literature review was conducted using multiple research databases. Data were extracted using multiple variables that were formulated incongruent with the study aim and then further analyzed. Results A total of 79 studies were included in our analysis after applying the exclusion criteria and removing of repeated studies, 109 patients were identified where they were diagnosed with intracranial hemorrhage after spine surgery with a mean age of 54 years. The most common type of hemorrhage was cerebellar hemorrhage (56.0%) followed by SDH and intraparenchymal hemorrhage; 23.9 and 17.4%, respectively. The most common spine surgery was laminectomy (70.6%), followed by fixation and fusion (50.5%), excision of spinal lesions was done in 20.2% of the patient, and discectomy (14.7%). Conclusion The data in this study showed that out of 112 patients with ICH, cerebellar hemorrhage was the most common type. ICH post–spine surgery is a rare complication and the real etiologies behind this complication are still unknown, cerebrospinal fluid drain and durotomy were suggested.

We aimed to estimate the nature and prevalence of paroxysmal nocturnal hemoglobinuria (PNH) among Omani patients. We performed a retrospective review of all patients who were tested for PNH by flow cytometry at the Sultan Qaboos University Hospital, Muscat, between 2012 and 2019. Manifestations, treatment modalities, and outcomes were assessed. A total of 10 patients were diagnosed or were on follow-up for PNH (median age 22.5 years). Clinical manifestations included fatigue (80%) and anemia (70%). Six patients had classical PNH with hemolysis, three had PNH in the context of aplastic anemia, and one patient had subclinical PNH. The median total clone size (type II + III) for neutrophils was 95.5 (range: 1.5–97) (FLAER/CD24) and for monocytes was 91.6 (range = 0.04–99) (FLAER/CD14). Four patients had clone sizes > 50% at the time of diagnosis. The median follow-up period of the patients was 62 months (range = 8–204 months). One patient suffered thrombosis. Three patients were on immunosuppressant agents, five were initiated on eculizumab, and four had a bone marrow transplant. No deaths were reported in the cohort. The estimated average incidence of PNH among Omani patients was 1.5 per 5 000 000. PNH is rare in the Omani population. The predominant presentation is hemolytic anemia.

Background Complex regional pain syndrome (CRPS) is a chronic inflammatory and neurological condition with a complex broad spectrum of symptoms and requires input from various clinical specialists such as orthopedic surgeons, anesthetists, rheumatologists, and rehabilitation physicians. Aim The aim is to study the awareness of CRPS among medical professionals (Orthopedics, Neurosurgeons, Family physicians, Internists). Method The study was conducted using a cross‐sectional survey. A postal questionnaire was sent online to different medical professionals. The questionnaire included two sections. The first section was about personal demographic whereas the second section was about the CRPS symptoms, diagnosis criteria, and management. Results The study resulted in a total number of 97 participants that filled the questionnaire completely with the highest number working at tertiary health centers (59.8%) followed by primary health centers (30.9%) and secondary health centers students (9.3%). Seventeen percent of the participants were aware about the diagnostic criteria of this condition, while only 15.4% have applied these criteria before. Awareness of risk factors and complications were 22.7% and 23.7%; respectively. The mean of the cumulative score out of 11 awareness among our participants was 2.48 (range; 0‐10). 37 (38.1%) of the participant scores 0/11 while none of the participants were able to score 11/11. Our study identified an association between years of experience and the level of awareness with a P value of .007. Conclusion The awareness of CRPS among medical professionals was not sufficient to met the recommendation of CRPS criteria and guideline. Physicians from different specialties need to increase their knowledge and awareness about this conditions.

Introduction Traumatic brain injuries (TBIs) occur due to severe head assault to a hard object, with headache and vomiting being amongst the most common presenting symptoms. Metoclopramide is an old antiemetic agent that has been used widely for nausea and vomiting in TBI patients. Aim A systematic review of the literature to investigate the safety of metoclopramide in treating TBI patients. Methods A literature review was conducted in six databases, where we determined the pertinence of a study to the inclusion criteria by assessing the title, keywords, and abstracts. Five studies were found to be relevant. Data were extracted using multiple variables that were formulated incongruent with the study aim and then further analyzed. Results The collective sample size was 93 patients with an average of age 38.5 years. As much as 51.6% were male and 48.6% were females. Most patients received 10 mg metoclopramide IV with a percentage of 77.4%, while only 22.5% received 20 mg IV metoclopramide. Seventy-one patients received metoclopramide alone and 22 received combination therapy. Headache was the most common reported side effect (46.2%), followed by anxiety and drowsiness with (39.7%) and (27.9%), respectively. Fatigue was reported in 24.7%, while dystonia was the least common and developed in only 5.3% of patients. Conclusion Metoclopramide is a common medication used to treat TBI patients in the emergency department. However, the review demonstrated that the central nervous system (CNS) side effect is excepted. Treatments with lower CNS side effects may be better options.
