Socio-Demographic and Clinical Profiles of Adult Attention Deficit Hyperactivity Disorder Patients in a University Hospital in Oman.

Objectives: Although attention deficit hyperactivity disorder (ADHD) is typically considered a condition affecting children, there is evidence that children diagnosed with ADHD continue to suffer from this condition after the age of 18. This study aimed to describe the socio-demographic and clinical characteristics of adult ADHD patients in Oman and evaluate their association with the disorder's different subtypes. Methods: This retrospective study included adult patients with ADHD from the outpatient clinic at Sultan Qaboos University Hospital, Muscat, Oman. Data from medical records from January 2018 to April 2020 were collected. Socio-demographic characteristics, clinical profiles and psychiatric comorbidities were examined. Results: This study included 100 adults who fulfilled the standard diagnosis of ADHD, with 54.0% (n = 54) and 46.0% (n = 46) from the inattentive and combined subtypes, respectively. It was found that ADHD was more prevalent among males (64.0%) than females (36.0%), with the inattentive subtype being more predominant among females. The ADHD patients with the inattentive subtype were associated with comorbid substance use disorders (odds ratio [OR] = 11.29; P = 0.049), personality disorders (OR = 7.96; P = 0.017) and major depressive disorder (OR = 15.94; P = 0.002) compared to patients predominantly with the combined subtype. Conclusion: This study echoes the findings from the current literature that adult patients with ADHD commonly have comorbid psychiatric disorders, leading to significant functional impairment. Psychiatric comorbidities must be identified and urgently treated for better clinical and functional outcomes in adult patients with ADHD.

Demographic and clinical characteristics of type 1 diabetes mellitus in omani children - single center experience.

OBJECTIVES: To describe the demographic characteristics and clinical presentation of Omani children with type 1 diabetes mellitus at Sultan Qaboos University Hospital, Muscat, Oman. METHODS: A retrospective analysis of all children with type 1 diabetes mellitus attending the Pediatric Endocrine Unit at Sultan Qaboos University Hospital, Oman from June 2006 to May 2013. RESULTS: One hundred and forty-four patients were included in the study. The mean±SD of age at diagnosis was 6.7 ± 3.7 years. The median duration of symptoms was 10 days (IQR; 5-14). The most commonly reported presenting symptoms were polyuria (94%), polydipsia (82%), and weight loss (59%). Diabetic ketoacidosis at initial presentation was diagnosed in 31% of the patients. Different insulin regimens were prescribed: multiple daily injections in 109 (76%) patients, twice daily insulin regimen in 23 (16%) patients, and insulin pump therapy in 12 (8%) patients. Family history of type 1 diabetes mellitus was present in 31 (22%) patients. There were no significant differences in presenting complaints (polyuria, p=0.182; polydipsia, p=0.848), duration of symptoms (p=0.331), reported weight loss (p=0.753), or diabetic ketoacidosis at presentation (p=0.608) between patients with and without family history of type 1 diabetes mellitus. CONCLUSION: Polyuria, polydipsia and weight loss are the most common presenting symptoms. Family history of type 1 diabetes mellitus is highly prevalent among the studied patients. Diabetic ketoacidosis was found to be less common in Oman compared to other diabetes centers in the Middle East.
