Kikuchi disease, also called, Kikuchi-Fujimoto disease or histiocytic necrotizing lymphadenitis, is a rare self-limiting illness with an unknown etiology and pathogenesis. It is predominantly seen among young females. The cardinal clinical features include fever and cervical lymphadenopathy. Skin eruptions have also been reported. In Oman, two cases have been reported to date, in 2005 and 2020, with only one case exhibiting skin manifestations. There is a paucity of disease in our country and worldwide. In this case report, we discuss the diagnosis of Kikuchi disease in a previously healthy 17-year-old Omani female who presented with fever, cervical lymphadenopathy, and malar rash. The clinical picture in this case resembled that of systemic lupus erythematosus. Due to the rarity of Kikuchi disease, particularly in our region, it is crucial to consider it as a differential diagnosis when a patient exhibits the aforementioned symptoms to prevent misdiagnosis and inappropriate treatment, as it can easily be misdiagnosed as systemic lupus erythematosus.

Objectives: Surgical training has evolved over the past few decades, with an increasing number of surgeons pursuing subspecialty training through fellowship programs across various surgical specialties. While published reports confirm this trend, few studies explored the factors that determine which fellowship training surgical residents would pursue. This cross-sectional study aims to investigate the factors influencing fellowship choices made by surgical trainees in Oman.

Methods: An online questionnaire, developed based on previously validated instruments, included 14 factors considered crucial for choosing a future career. Statistical analysis was performed to determine item-level validity, scale-level validity, and reliability. The survey was distributed via email and closed after six weeks for data analysis.

Results: The survey achieved a response rate of 60.9%. The analysis revealed that the most influential factor among surveyed surgeons in selecting a subspecialty was prestige, with an average score of 2.7. The least reported influential factors were variety of cases (average score of 1.8) and personal interest (average score of 1.4). Only 57.7% of respondents received career choice guidance.

Conclusions: Factors influencing the choice of surgical subspecialties vary among the different groups. This information can be valuable in designing programs and structuring professional career guidance and counseling.

Methemoglobinemia is a rare dyshemoglobin disorder which can either be congenital or acquired. Dyshemoglobin disorders can be asymptomatic or symptomatic. We narrate the case of a 12-year-old girl who presented with a fever, cough, and oxygen saturation of 85%. She was diagnosed with COVID-19, along with a large atrial septal defect and pulmonary arterial hypertension. Arterial blood gas analysis revealed normal partial pressure of oxygen and on 100% exposure to oxygen, blood color turned chocolate brown. After the resolution of COVID-19 in 10 days, the patient was treated with oral ascorbic acid and successful atrial septal defect repair. It is important to suspect dyshemoglobin disorder in a patient who presents with hypoxia/hypoxemia.

Idiopathic capillary leak syndrome, also known as Clarkson's Disease, is a rare cause of hypovolemic shock that physicians should be aware of. It is characterized by a state of hypovolemia with features of widespread fluid third spacing and poses diagnostic and therapeutic challenges. Here, we present a challenging case of a 36-year-old woman who experienced recurrent episodes of widespread edema and hypovolemic shock symptoms suggestive of capillary leak syndrome. The resuscitative and therapeutic measures employed in managing this disease are described in this case report.

Objectives: To evaluate the impact of Pulmonary Arterial Hypertension (PAH) therapies on the incidence of pericardial effusion and its prognostic implications for patient survival.

Methods: This retrospective cohort study included 60 patients diagnosed with PAH at a high-volume tertiary care center, treated with intravenous or subcutaneous prostanoids. Data were collected from 2015 to 2019, including echocardiographic assessments, right heart catheterization, World Health Organization functional class evaluations, six-minute walk distance tests, and biomarkers such as brain natriuretic peptide and N-terminal prohormone of brain natriuretic peptide. Follow-up was conducted at least 90 days post-treatment initiation.

Results: Pericardial effusion was observed in 31.7% of patients before therapy. Patients with moderate to large effusions had a significantly higher mortality risk (HR = 1.92; 95% CI 1.1-44.78; p =0.0044), while small effusions appeared protective (HR = 0.27; 95% CI 0.15-0.48; p =0.006). Survival rates declined from 89% at one year to 71% at three years post-therapy, with effusion presence correlating with more severe PAH manifestations.

Conclusions: Initial pericardial effusion severity is a critical predictor of mortality in PAH patients. Early assessment and stratified management of pericardial effusion are essential for optimizing therapeutic outcomes in PAH management. Future research should explore targeted interventions for managing pericardial effusion to improve patient prognosis.

Objectives: Several studies have explored the opinions of healthcare workers on the use of complementary and alternative medicine (CAM) in epilepsy treatment. We sought to survey the views of non-neurologist and non-psychiatrist physicians in Oman on the use of CAM for epilepsy.

Methods: We used convenience sampling to recruit physicians (except neurologists and psychiatrists) from all 11 governorates of Oman. The online questionnaire was open to physicians from 5 January 2022 to 15 February 2023. This study collected anonymous data on their demographics, discipline, work settings, geographical area, and years of practice. Additionally, participants were asked to answer questions about their perception of CAM use and its effectiveness in treating epilepsy.

Results: A total of 190 physicians participated, of whom 69.5% were men. Respondents were mostly 36 to 45 years old (51.1%). The majority (52.1%) were general practitioners, 21.1% were internists, 17.9% were pediatricians, and 8.9% were family physicians. Most participants (n = 144; 75.8%) believed that CAM may help treat patients with epilepsy (PWE). The most common therapies that participants considered helpful were meditation (46.0%), prayers (44.7%), yoga (32.6%), and exercise (31.1%).

Conclusions: While the evidence supporting the use of CAM for the treatment of epilepsy is scarce, this survey showed that most physicians (non-neurologists and non-psychiatrists), who manage PWE in Oman, believed that some CAM modalities would help treat epilepsy. Well-designed controlled trials are needed to provide reliable evidence on the usefulness of CAM options in PWE.

Autosomal dominant polycystic kidney disease (ADPKD) is a common inherited condition characterized by the growth of multiple bilateral cysts in the kidneys. We describe the case of a 35-year-old male with combined ADPKD and type 1 diabetes mellitus with a strong family history of both. At the age of 32, he developed end-stage kidney disease for which he underwent preemptive simultaneous pancreatic and kidney transplant, which in turn led to multiple perioperative complications. Evaluation of familial clustering of genetic disease is critical in genetic epidemiology and precision medicine as it enables estimation of lifetime disease risk and early assessment as well as detection of the disease among one's siblings.

Objectives: The existing biomarkers used to promptly identify graft dysfunction after kidney transplantation lack consistency. Neutrophil gelatinase-associated lipocalin (NGAL) appears to be a promising biomarker but its levels measured from serum and urine have demonstrated varying predictive values. Our study aimed to explore the potential of NGAL as a biomarker in predicting graft dysfunction in kidney transplant patients, including live and deceased donor recipients.

Methods: A single-centered observational cohort study with live and deceased kidney recipients as participants was conducted between 2018 and 2022 at a tertiary care hospital in Southern India. Serum creatinine levels were monitored daily; creatinine reduction on day two and day seven were calculated. The recipients were categorized based on graft recovery into three groups: delayed graft function (DGF), slow graft function (SGF), or immediate graft function (IGF). Analysis of serum and urine NGAL was conducted two hours after the transplant and their predictive values were evaluated by the area under the curves (AUC) method.

Results: Of the 40 participants, 34 (85.0%) received their transplant from live-related donors, while six (15.0%) received kidneys from deceased donors. DGF occurred in four (10.0%) patients, SGF in 12 (30.0%), and 24 (60.0%) patients achieved IGF. Serum NGAL demonstrated higher sensitivity compared to urine NGAL. At a cut-off value of 678 ng/mL (AUC = 0.77), serum NGAL showed 90.0% sensitivity and 53.0% specificity. Urine NGAL had 70.0% sensitivity and 74.0% specificity at a cut-off value of 489 ng/mL (AUC = 0.72).

Conclusions: Kidney recipients in SGF and DGF categories had elevated levels of serum and urine NGAL compared to those without IGF. Although serum NGAL showed higher sensitivity than urine NGAL in predicting graft dysfunction, both markers lacked the specificity needed for accurate predictions.

Objectives: There is a dearth of research regarding the motivations and experiences of Omani nationals who travel abroad for medical treatment, especially for neurological diseases. The primary objective was to examine and draw comparisons between Omani adults and children with neurological disorders who pursued medical treatment abroad after being evaluated by local specialists. The study also aimed to gain insights into these patients' motivations and experiences. A related objective was to explore the sociocultural factors and family dynamics that shape the attitudes towards illness and treatment seeking.

Methods: In this cross-sectional study, Omani patients treated at a major tertiary hospital in Muscat for neurological disorders and subsequently traveled overseas for treatment were identified and administered a structured questionnaire.

Results: The participants were 116 Omani nationals (62 children and 54 adults) with neurological disorders, diagnosed predominantly with epilepsy (71.6%) followed by developmental delay, muscular dystrophy, and encephalopathy. Only 19.8% of patients received government sponsorship. The majority (69.8%) followed the recommendations of family members. Most (63.8%) participants reported positive outcomes after treatment abroad, though 4.3% developed complications and 5.2% acquired nosocomial infections. Most (83.6%) participants opined that the treatment they received overseas was comparable to what they would have received in Oman. There were no significant differences between children and adults in most of these aspects.

Conclusions: Public awareness should be increased regarding the pros and cons of medical tourism. Patients must be made aware of the advanced treatment facilities available locally. Efforts should be made to enhance patient outcomes and satisfaction by adopting more efficient and patient-friendly processes.
