Multiorgan dysfunction syndrome (MODS) remains a major complication and challenge to treat patients with critical illness in different intensive care unit settings. The exact mechanism and pathophysiology of MODS is complex and remains unexplored. We reviewed the literature from January 2011 to August 2019 to analyze the underlying mechanisms, prognostic factors, MODS scoring systems, organ systems dysfunctions, and the management of MODS. We used the search engines PubMed, MEDLINE, Scopus, and Google Scholar with the keywords “multiple organ dysfunction syndrome,” “intensive care units,” “multiorgan failure,” “MODS scoring system,” and “MODS management.” The initial search yielded 3550 abstracts, of which 91 articles were relevant to the scope of the present article. A better understanding of a disease course will help differentiate the signs of an intense inflammatory response from the early onset of sepsis and minimize the inappropriate use of medications. This, in turn, will promote organtargeted therapy and prevent occurrence and progression of MODS.

Background: Surgeons may encounter unexpected anatomical or pathological findings during various bariatric surgical procedures for which they must make prompt and critical decisions that had not been planned prior to the operation. In this practice review, we present our experiences with unexpected challenges and on-table decision making in bariatric surgery to share our knowledge with colleagues who may encounter the same challenges during bariatric surgery. This paper's content is of applied learning and practical value focusing on challenging intraoperative decision making; however, it does not discuss the details of the various techniques used during surgery.

Methods: This work is a single-center retrospective review of operations carried out on patients who had unexpected intraoperative findings during bariatric surgery despite the implementation of detailed preoperative evaluations that would have otherwise suggested standard procedures. These findings resulted in abandoned surgery or laparoscopic sleeve gastrectomy instead of the intended Roux-en-Y gastric bypass.

Results: A total of 449 patients had received various bariatric interventions in our unit between 2012 and 2016. Eleven patients, representing approximately 2.4% of the total number of patients surveyed had met the inclusion criteria and were added to the final list for analysis. The mean age of the included patients was 40.82 years (range: 30–51 years), and seven of the patients, representing approximately 63.6% of the included cases, were female. The mean body mass index of the 11 cases was 40.8 (range: 38–48). Only two cases (18.9%) had had their surgery abandoned; the rest (81.1%) had received laparoscopic sleeve gastrectomy instead of Roux-en-Y gastric bypass. None of the 11 patients had perioperative morbidity or mortality.

Conclusion: Intraoperative decision making for unexpected findings in bariatric surgery is challenging. In these circumstances, surgeons must make prompt and critical decisions, including abandoning the operation. The available literature on this subject is unsurprisingly limited because of the rarity of such findings.

Background: Infective endocarditis (IE) is a serious and potentially life-threatening disease. The epidemiology, treatment options, and outcomes have changed considerably over the last two decades. The aim of the study was to describe the epidemiology, clinical characteristics, and outcomes of patients with IE in Qatar.

Methods: Patients were identified from Hamad Medical Corporation hospitals’ electronic records, the national referral center for the State of Qatar. We included those aged ≥ 18 years with Duke Criteria-based diagnosis of IE during the period from January 2015 to September 2017. Demographic and clinical data were retrieved. Descriptive statistics were performed, and logistic regression analysis was used to describe the relationship between patient characteristics and all-cause in-hospital mortality. All potentially relevant variables were included in the univariate analysis, while those with p < 0.1 in the univariate logistic regression model were included in the multivariate analysis. For the final model, we calculated odds ratios (OR) adjusted for each of the variables included, along with their 95% confidence intervals (95% CI). Data were analyzed using STATA software version 15 (StataCorp, College Station, Texas, USA). The study was approved by the Institutional Research Board with a waiver for informed consent.

Results: Fifty-seven cases were included, of which 70% were males. The mean age was 51 years ( ± 16.8 years). Eleven (19%) were associated with prosthetic valves, and 6 (11%) with implantable cardiac devices. Fever (84%), dyspnea (46%), and heart failure (37%) were the most common presentations. Only 58% of patients had known preexisting valvular heart disease or an intracardiac device. Skin infections (10 patients, 18%) were the most prevalent portals of infection, followed by venous catheters, recent valve surgery, and implantable cardiac devices. Staphylococci were implicated in 19 (34%) and Streptococcaceae in 9 (16%) patients, whereas 21 (37%) patients were culture negative. Left-side IE (49 patients, 86%) was predominant. Acute kidney injury (AKI) (17 patients, 30%) and heart failure (11 patients, 19%) were common complications. The majority of patients received targeted antimicrobial therapy with at least two active agents. Only 9 (16%) patients underwent surgical intervention. Fourteen (25%) patients died of any cause before hospital discharge. Logistic regression analysis identified septic shock [OR 57.8, 95% CI 2.6–1360.2; p < 0.01] and AKI OR 33.9, 95% CI 2.9–398.1; p < 0.01) as the only risk factors independently associated with in-hospital mortality.

Conclusion: Staphylococci are the most common microbiological cause of IE in Qatar. Surgical intervention is uncommon, and mortality is relatively high. Our findings suggest that efforts should be directed toward improving IE prevention strategies in high-risk patients, encouraging early microbiological investigations and improving medical and surgical management.

Reactive arthritis (ReA) is a syndrome of arthritis and tenosynovitis with defined extra-articular manifestations following certain infections. Despite being recognized a long time ago, debates still surrounds its definition. It is still unclear if the spectrum of the disease should include arthritis induced by other than the classical organisms. Here, we present an unusual cause of ReA. A young healthy female patient presented with acute polyarthritis and acute urticaria after 2 weeks of diarrheal illness. She was found to have blastocystis in the stool microscopy. Extensive evaluation ruled out other causes of her arthritis. She received metronidazole with a short course of NSAIDS and steroids with complete resolution of her skin and joint symptoms. She was followed for six months with no recurrence of arthritis or urticaria. Blastocystis sp. is a parasite that is prevalent in developing countries. It has been linked to isolated ReA or isolated urticaria among a few other case reports. This is the very first case to have blastocystis induced ReA that coexisted with acute urticaria. Upon review of the literature, we found that blastocystis induced ReA affects mainly young and middle-aged females such as in our case. The arthritis is usually settled with the parasite eradication. Finally, urticaria might be a distinguishing feature for blastocystis induced ReA that requires specific antimicrobial therapy.

Our article outlines a perspective on COVID-19 reactivation with considerations of implored commentary on behalf of the medical community regarding open discourse about this subject. Such a topic is paramount in elucidating parameters that pertain to testing, and subsequent public health population dynamics once uneventful cases pass. We argue that what some may refer to as a reinfection or reactivation of the virus, is actually a result of prolonged shedding of the virus complemented with occasional false positives/negatives and lab errors. This article was written with the perspective of informing in addition to engage discussions that distill salient, evidence-based characterization of COVID-19. We hope to recruit fellow academics in medicine who see trends in their own respective communities about people who re-test, and to explore their clinical outcomes.

Microlaryngoscopy for benign vocal cord lesion excision is a procedure with good outcomes and relatively few complications that is performed worldwide. The anterior one-third of the vocal cords is a relatively common site to find benign polyps, and the excision of cases with adequate laryngeal exposure is relatively easy. However, they can sometimes present a challenge when laryngeal exposure is suboptimal, which leads to trouble in accessing the site. The factors that can lead to difficulties in laryngeal exposure are numerous, such as restricted mouth opening, limited neck extension, large tongue size, and others. The preoperative prediction of difficult laryngeal exposure (DLE) can be obtained by different scoring and grading systems. We have used the Laryngoscore in this case. However, management options for such cases remain limited. Here, we present a case that was managed using channeled cup forceps under fiberoptic endoscopy with the STRIVE-Hi technique used to administer anesthesia.

Background: Third ventricular colloid cysts are benign but may cause acute hydrocephalus, raised intracranial pressure, decreased consciousness level, and sudden death. These ventricular colloid cysts associated with stunned myocardium are rarely reported in the literature. This study reported a case of a third ventricular colloid cyst presented as acute hydrocephalus complicated with severe neurogenic pulmonary edema, stunned myocardium, and heart failure, which survived at the end.

Case presentation: A 29-year-old woman presented to the emergency department with one day history of headache, vomiting, and altered consciousness level. Early brain imaging showed a cyst in the third ventricle. The patient rapidly deteriorated neurologically and developed severe pulmonary edema and heart failure requiring immediate external ventricular drain and heart failure management. Once stabilized, she underwent endoscopic excision of the ventricular cyst. Histopathology confirmed the diagnosis of colloidal cyst. She survived all these acute life-threatening events, improved, and stabilized, and was discharged home. She was followed up in outpatient clinics after 6 months of discharge with no symptoms or neurological deficit.

Conclusion: A third ventricular colloid cyst can cause acute hydrocephalus leading to stunned myocardium requiring immediate surgical intervention, advanced hemodynamic monitoring, and acute heart failure management.

Background: Musculoskeletal (MSK) conditions are considered a significant public health problem on account of their high prevalence in communities worldwide and their pervasive impact. Knowledge of the epidemiology of MSK symptoms and diseases is lacking in Qatar. Obtaining this information will guide local health policymakers in the future strategic planning of the health budget.

Objective: To estimate the prevalence rate of MSK disorders in the Qatari population above 15 years of age using the Community Oriented Program for the Control of Rheumatic Disease (COPCORD) survey.

Methods: This cross-sectional study targeted 1000 Qatari participants, including 500 males and 500 females. A door-to-door survey was conducted using the Arabic version of the COPCORD questionnaire with the help of research assistants. Participants with positive surveys were asked to visit Hamad General Hospital Rheumatology outpatient clinics for clinical evaluation by a rheumatologist. When necessary, laboratory testing and X-rays were conducted to confirm any MSK diagnosis.

Results: A total of 1239 (males, 50.8%) Qatari individuals randomly selected from the different municipalities of Qatar completed the COPCORD survey. Among the participants, 563 (45.4%) screened positive for MSK pain. Knee pain (24.5%) and back pain (23.3%) were the most common sites of pain, and both conditions showed no gender predominance (p = 0.073 and 0.108, respectively). Shoulder, wrist, hand, hip, and neck pain were significantly predominant in females (p < 0.001 for all). A total of 237 MSK disorders were diagnosed in 196 (15.8%) participants, including 181 degenerative joint diseases, 52 soft-tissue rheumatism conditions, and 4 autoimmune inflammatory disorders. Among degenerative joint diseases, knee osteoarthritis (6.4%) was the most common. Among soft-tissue rheumatic conditions, muscular lower back pain (1.9%), myofascial neck pain (0.64%), generalized body pain (0.32%), and shoulder tendinitis (0.7%) were the most common diseases. The autoimmune inflammatory disorders identified included rheumatoid arthritis (n = 2), connective tissue disease (n = 1), and inflammatory bowel disease-associated arthritis (n = 1).

Conclusion: The overall prevalence rate of MSK disorders in this small cross-sectional cohort of Qatari individuals was 15.8%. Knee pain (24.5%) and knee osteoarthritis (6.4%) were the most common MSK complaints and diagnosis in the studied Qatari population. This study guides future efforts directed toward the prevention and management of MSK diseases. Further studies with a larger sample size are needed to verify the findings.

Myositis and rhabdomyolysis are the same forms of myopathy, with rhabdomyolysis being a more severe form of myopathy. Gabapentin is frequently used in patients with spinal cord injury for neuropathic pain. We report a case of probable gabapentin-induced myositis in a patient with spinal cord injury who was on an increasing dose of gabapentin.

This paraplegic patient was receiving an increasing dose of gabapentin for neuropathic pain in the lower limbs. Gabapentin-induced myositis was diagnosed by a combination of new-onset generalized body pain with tenderness, an increase in creatine kinase, elevated myoglobin levels, and a score of 6 on the Naranjo adverse drug reaction probability scale. Withdrawal of the gabapentin resolved the symptoms completely. Blood parameters became normal within two weeks.

We suggest that myopathy, in the form of myositis, should be recognized as a potential side effect of gabapentin in the literature.

Here we reported a case of a 17-year-old man with a history of weakness, vertigo, nausea, vomiting and dark stool within the last three months prior to admission. He was taken to the Emergency Room in a state of shock. After resuscitation, vital signs became stable, but due to low hemoglobin (HB = 5 g/dl), to find the source of bleeding, endoscopy was performed and a mass in the duodenum was detected. The pathology report was metastatic germ cell tumor. On genital physical exam (PE) there was a mass in the right testis; thus, the patient underwent radical orchiectomy and choriocarcinoma was diagnosed. The patient then received chemotherapy for six months, and he responded well to the treatment. This case report confirmed that genital PE should be part of a patients visit, even when we cannot find logical relation between clinical presentation and genital PE.

Background: Teething is a physiological process experienced by all children. However, many unrelated illnesses are blamed on teething.

Objective: The aim of this study was to assess mothers’ beliefs toward teething and to investigate the practices preferred by mothers to alleviate symptoms that might accompany the teething process.

Methods: A cross-sectional study was conducted in Basra. The study population includes mothers of young children aged (6–30) months who had at least one erupted primary tooth, and who had no history of medical or systemic disease that might affect teething. Two hundred mothers of different age groups and educational backgrounds responded to a questionnaire that included information on the child's age and birth order, mother's age, level of education, occupation, number of children, beliefs toward teething symptoms, and the practices preferred to relieve the attributed symptoms. Data has been presented in numbers and percentages, the Chi-square test was performed where appropriate, and a p value of < 0.05 was considered significant.

Results: All (100%) participants attributed at least one symptom or sign to the teething process. The most common symptoms reported were fever (70%), diarrhea (68.5%), and sleep disturbance (63.5%).

Sixty-eight percent of mothers believed teething remedies were effective; only 10 (5%) did not give any treatment. Over half (62%) gave medications, such as antipyretics, antibiotics, and antidiarrheal agents. Some used teething gels (29%), pacifiers (50%), gum massage (22%), and hard foods such as biscuits and carrots (43.5%). Mothers of various educational levels reported attributed symptoms, and the result was statistically significant (p < 0.05). Mothers of a firstborn child were found to have a higher tendency to attribute symptoms to teething than those who had previous experience with children (p < 0.05).

Discussion and conclusions: Teething myths and misconceptions are common among mothers. The study identified a significant number of doctors, dentists, and pharmacists still attribute many symptoms and signs to teething despite the lack of supporting evidence. Therefore, the findings of this study highlight the need for continuous medical education and nationwide prospective studies to eradicate these false beliefs.

The modified Valsalva maneuver (MVM) has never before been performed in the prehospital setting by the Hamad Medical Corporation Ambulance Service (HMCAS) clinicians in the State of Qatar. Currently, their clinical practice guidelines (CPG) prescribe the vagal maneuver (VM) using a 10 cc syringe as first-line therapy for patients presenting with symptomatic paroxysmal supraventricular tachycardia (pSVT). The effectiveness of the MVM in terminating pSVT compared to the traditional VM is well documented, although prehospital studies in this area are lacking. In this case, a generally healthy, 47-year-old male migrant worker presented with new-onset symptomatic pSVT, which was successfully terminated by a MVM after initial failed attempts of the traditional VM. The MVM is a postural technique performed by initially placing the patient in a semirecumbent position. The patient is then encouraged to blow into a manometer to achieve a 40 mmHg intrathoracic pressure for 15 seconds. Once the 40 mmHg intrathoracic pressure is achieved, the patient is repositioned supine, and their legs are raised passively to 45 degrees for 15 seconds. The patient is then returned to the semirecumbent position for 45 seconds before cardiac rhythm reassessment. The MVM has shown to have an increased termination rate of pSVT with no documented serious adverse events. The MVM can be performed in a time-effective manner and is cost effective as intravenous (IV) cannulation is not required. The prevention of adenosine-associated transient asystole is prevented. It is recommended that ambulance services consider the inclusion of the MVM in their CPGs for the treatment of new-onset pSVT.

Introduction: Aortic dissection is a cardiovascular emergency with an overall in-hospital mortality rate of 27.4%, and with every hour without intervention, the mortality rate increases by 1%–2% in the first 48 hours. Thoracic aortic dissection typically presents with tearing chest, back, or abdominal pain. Coronavirus disease 2019 (COVID-19) is a viral disease caused by severe acute respiratory syndrome–coronavirus 2 (SARS–Cov2), which has been declared a pandemic by the World Health Organization (WHO) and usually manifests with respiratory symptoms, including cough, shortness of breath, flu-like symptoms, and fever. This case report highlights an important impact of the COVID-19 pandemic on the identification and management of aortic dissection in the emergency department.

Case report: A 35-year-old Bahraini male, a suspected case of Marfan syndrome, presented with complaints of shortness of breath and worsening productive cough after returning from the United States (U.S). He denied any chest, back, or abdominal pain, dizziness, weakness in any limb, gait disturbance, headache, or change in vision. He was considered high risk for COVID-19 because of the recent travel and respiratory symptoms and was diagnosed incidentally with ascending aortic dissection along with a right lung consolidation. His SARS–Cov2 PCR came negative thrice during hospital stay, and he underwent elective cardiothoracic surgery.

Conclusion: The COVID-19 pandemic has been a major stressor for the healthcare system worldwide, inflicting serious threats. Aortic dissection is one of the major life-threatening diseases that needs to be identified early on in the emergency department; however, in this case delayed diagnosis raised significant concerns due to underlying evolving triaging system for COVID-19 and atypical and overlapping clinical presentation. Further research is needed to look for COVID-19–associated factors, affecting the standard of care in the emergency department. Improving handover can directly impact patient care; therefore, it should be optimized.
