Objectives: Pulmonary embolism (PE) is increasingly prevalent in Oman. The aim of this situational analysis of PE among Omani patients was to study its predisposing factors, diagnostic issues, and optimal management., Methods: In this retrospective cross-sectional situational analysis, the subjects were Omani patients who were diagnosed with acute PE using computed tomography pulmonary angiogram from 2010-2021. The required data was collected from the hospital database and statistically analyzed., Results: The subjects were 438 patients diagnosed with PE, with a mean age of 53.3±18.5 years and mean body mass index of 29.7±7.3 kg/m 2 . Males were in a slight majority (223; 50.9%) and were older (55.0±18.5 years) than females (51.5±18.3 years). Two-thirds of the PE patients had hypertension and one-third had diabetes mellitus. Most patients presented with dyspnea and chest pain. Syncope was more common in females compared to males who mostly presented with hemoptysis. Nearly half of the patients had abnormal echocardiogram, and males had lower mean ejection fraction compared to females. Different modalities of management were used to treat patients' PE. Heparin was the most used anticoagulant followed by warfarin and direct oral anticoagulants. Out of the 122 PE patients who died during the study period, PE was the direct cause of death of 68 patients. The mortality was higher in males than in females., Conclusions: The incidence of acute PE was similar among both male and female Omani patients. However, there were sex differences in risk factors, symptoms, investigations, and management of PE. Females presented with more severe PE, but mortality was higher in males., (The OMJ is Published Bimonthly and Copyrighted 2023 by the OMSB.)

Objectives: To describe the demographic distribution of cystic fibrosis (CF) in Omani children, estimate the national prevalence, and provide updated mutational panels of the cystic fibrosis transmembrane conductance regulator (CFTR) gene., Methods: We conducted a retrospective cross-sectional study of all CF patients who had been diagnosed and followed-up at Sultan Qaboos University Hospital and Royal Hospital in Oman between 2006 and 2020. Data were collected from electronic hospital records and telephone interviews., Results: A total of 227 patients with CF were included in the study. Geographical clusters of the disease were identified in the governorates of Al-Batinah, A'Dhahirah, and A'Dakhiliyah. Parental consanguinity and family history of CF were present in 68.3% and 69.6% of the patients, respectively. The most common CFTR mutation was p.Ser549Arg (52.0%), followed by p.Phe508del (12.3%), and c.2988+1G>A (4.4%). Three novel CFTR mutations were identified, viz., Leu88TyrFs*, p.Asp192Val, and c.4242+1G>C., Conclusions: The estimated prevalence of CF in Oman is 10.3 per 100 000 individuals. Premarital genetic counseling and preimplantation genetic testing are recommended in CF-prevalent regions., (The OMJ is Published Bimonthly and Copyrighted 2022 by the OMSB.)

Objectives: Our study aimed to estimate the rate of white coat hypertension (WCH) and effect, and masked hypertension in patients attending a tertiary care hospital for 24 hour ambulatory blood pressure monitoring (24-h ABPM)., Methods: A total of 231 adult patients were referred to the Department of Clinical Physiology at Sultan Qaboos University Hospital, Muscat, for ABPM, between January 2010 and June 2012. The following data were gathered and analyzed: demographic data, clinic blood pressure (BP) measurements, and 24-h BP profile from ABPM. Thirty-two patients were excluded and the final analysis included 199 patients., Results: There were 105 (52.8%) women and 94 (47.2%) men studied. The mean age of patients was 46±15 years and most patients were overweight with a mean BMI of 29.6±5kg/m(2). Around half of patients (53.8%) were on one or more antihypertensive medications. WCH was found in 10.6% and white coat effect was found in 16% of patients. The majority of patients (57%) with WCH were aged 40 years or above. Masked hypertension was present in 6% of patients and masked uncontrolled hypertension in 8.5% of patients., Conclusions: Our study showed that WCH and effect, and masked hypertension are common in hypertensive patients. Identifying these patients will have an impact on their management. However, the results of the study should be interpreted within the context of its limitations. Prospective randomized community and hospital-based studies should be conducted to estimate the true prevalence in the general population as well as in hypertensive patients.

Objectives: This survey aims to assess the current levels of asthma control as reported by patients attending chest specialist clinic by using the Asthma Control Test (ACT) questionnaire., Methods: Current levels of asthma control were assessed using the ACT questionnaire, and a brief instrument developed to assess asthma control in a clinical setting. 141 (100 females) patients aged 13 years and above were recruited from the chest clinic of Royal hospital, a tertiary hospital in the Sultanate of Oman. The ACT questionnaire was administered only from the second visit., Results: The result showed that 61% of patients scored between "20 and 25" (well controlled), 17.7% of the patients scored between "15 and 19" (not well controlled), and the rest 21.3% scored between "5 and 14" (poorly controlled). More than 50% of the patients reported that their asthma had an impact in work, school or home Nocturnal symptoms were reported by 66% and the use of rescue medications by 70%. Patient perception of asthma control did not match their symptom severity as more than 65% considered their asthma controlled despite the fact that their symptoms limited their daily activities and disturbed their sleep., Conclusion: The current level of asthma control among the study patients falls far short of the goals for long-term asthma management and patients' perception of asthma control is different from their actual asthma control.
