Prevalence of anxiety, depression, and post-traumatic stress disorder among Omani children and adolescents diagnosed with cancer: a prospective cross-sectional study.

BACKGROUND: Children and adolescents diagnosed with cancer often experience psychological distress, encompassing anxiety, depression, and post-traumatic stress disorder (PTSD). This study aimed to evaluate the prevalence of these conditions among Omani children and adolescents diagnosed with cancer, alongside identifying contributing factors. METHODS: A prospective cross-sectional study was conducted from October 2021 to June 2023 among a cohort of Omani children and adolescents (6-18 years old) diagnosed with cancer at three primary cancer referral centres in Oman. Validated Arabic-language versions of the Screen for Child Anxiety Related Disorders, the Center for Epidemiologic Studies Depression Scale for Children, and the Impact of Event Scale-Revised instruments were used to assess symptoms of anxiety, depression, and PTSD, respectively. An initial assessment (T1) was undertaken within the first 3 months of diagnosis, followed by a second assessment (T2) 3-6 months later. RESULTS: Of 113 eligible participants, 101 agreed to participate in the study (response rate: 95.6%), with 92 (91.0%) completing both assessments and included in the final analysis. Prevalence rates of anxiety, depression, and PTSD decreased from 43.5%, 56.5%, and 32.6%, respectively, at T1, to 38.0%, 35.9%, and 23.9% at T2. All average scores were below diagnostic cut-off points, except for the depression score at T1. Anxiety and depression scores decreased significantly (p = 0.043 and 0.001, respectively) between T1 and T2, as did the overall prevalence of depression (p = 0.004). At T1, linear regression analysis showed significant correlations between anxiety scores and the child's age and PTSD score (p < 0.05); these variables were also correlated with depression scores (p ≤ 0.001). At T2, significant correlations were observed between anxiety scores and the child's age and PTSD scores (p < 0.001). At both T1 and T2, anxiety, depression, and PTSD scores remained significantly correlated (p < 0.001). CONCLUSIONS: Omani children and adolescents recently diagnosed with cancer exhibit a high prevalence of anxiety, depression, and PTSD over time. Age-appropriate communication, ongoing support, and mental health services are recommended to help this patient group cope with their diagnosis and manage their emotional wellbeing. There is a need for future research to determine the effectiveness of specific psychological interventions in reducing the frequency of these disorders.

Severe Recurrent Nocturnal Hypoglycemia During Chemotherapy With 6-mercaptopurine in 2 Children With Acute Lymphoblastic Leukemia.

Mercaptopurine (6MP) and methotrexate are the cornerstones of maintenance therapy in pediatric patients with acute lymphoblastic leukemia. However, although bone marrow suppression and liver dysfunction are common side effects of these antimetabolites, 6MP-induced hypoglycemia during the maintenance phase is rare. Guidelines and international protocols are well established for the management of bone marrow suppression and liver dysfunction, but promptly identifying 6MP-induced hypoglycemia is the key to its control. Here we report 2 cases of leukemia that developed hypoglycemia during the maintenance phase. Both patients were boys younger than 6 years of age and both suffered symptomatic morning hypoglycemia induced by 6MP (which was diagnosed after excluding all other possible causes). Successful management included changing the time of 6MP administration from evening to morning. Other management options are also discussed.

Extrarenal Wilms' Tumour of the Ovary: A case report.

Wilms' tumour (nephroblastoma) is the most common abdominal malignancy in children. Extrarenal Wilms' tumour is rare, with limited reports in the literature. We report a two-year-old girl who presented to a tertiary care hospital in Muscat, Oman, in 2019 with an abdominal mass. The patient was diagnosed with unilateral ovarian Wilms' tumour (initially diagnosed by closed biopsy and confirmed later by histopathology study of the excised tumour). This report highlights the unusual location and presentation of Wilms' tumour and presents the medical challenge in both the initial clinical impression and pathological diagnosis. Furthermore, this report details the therapeutic plan and shows the good outcome achieved by using the classic renal Wilms' tumour therapy protocols.

Tuning a pyrazoline-based fluorogenic reagent, 3-naphthyl-1-(4-trifluoromethyl)-5-(4-carboxy phenyl)-2-pyrazoline for sensitive precolumn derivatization of aliphatic alcohols and trace analysis by RP-HPLC with fluorescence detection.

A new member of the pyrazoline family, 3-naphthyl-1-(4-trifluoromethyl)-5-(4-carboxy phenyl)-2-pyrazoline has been evaluated as a precolumn derivatization reagent for the analysis of primary alcohols using HPLC. The simultaneous separation of eight alcohol derivatives (C1 -C8 ) within 15 min was achieved on a reverse-phase C8 column with an isocratic elution mode. The derivatives were detected with fluorescence at an emission wavelength of 470 nm when excited at 360 nm. The identification of the corresponding derivatives was carried out by LC-MS/MS and all showed their characteristic parent peak in negative ion mode. The proposed method was validated using normal analytical tools and was found to be excellent. As a preliminary application, our method was used to determine ethanol concentration in alcohol-containing chocolates and cough syrup.

Coronavirus Disease 2019 Infection in Children With Sickle Cell Disease: Case Series From Oman.

BACKGROUND: In March 2020, WHO announced Coronavirus Disease 2019 (COVID-19) outbreak a global pandemic. During this pandemic, patients with sickle cell disease (SCD) have been placed in the "high-risk" category of the population. Although there are numerous publications describing COVID-19 in adult patients, pediatric data are still limited. OBSERVATION: Herein, we report case series of 5 sickle cell disease Omani children who got infected with COVID-19; illustrating their different ways of presentation, management and highlighting the outcomes. CONCLUSION: Although SCD patients are considered as a high-risk group, all of the observed patients, and whose cases are reported here, have recovered. A large scale of SCD cases should be studied to reach more conclusive results.

Hepatoblastomas in Oman: Unveiling success.

OBJECTIVES: Primary malignant liver tumours account for more than 1% of all paediatric malignancies, with the most common form being hepatoblastomas (HB). Such malignancies among Arab populations have rarely been addressed in the literature. Using data from Oman's sole national referral centre for childhood solid malignancies, this study aimed to present the nationwide Omani experience with HB over the past 21 years. METHODS: This retrospective study reviewed the medical records of all children with HB who were managed in the Royal Hospital, Muscat, Oman, between January 1991 and April 2012. Clinical, radiological and laboratory characteristics were examined as well as treatments and outcomes. RESULTS: During the study period, 15 patients with HB were treated. Of these, 10 have survived to date. Nine of the survivors were no longer receiving treatment and one patient still had the disease but was in a stable condition. Of the remaining five patients, three did not survive and two were lost to follow-up. The survival rate among patients who completed therapy was 91%. CONCLUSION: HB has an excellent prognosis in Oman. The main obstacle to improving outcomes among Omani patients is non-compliance with therapy.
