Negative pressure pulmonary edema following laryngospasm after dental abscess: A case report.

Negative pressure pulmonary edema (NPPE), also known as post-obstructive pulmonary edema, is a rare and life-threatening condition. It occurs when a person breathes against an obstructed glottis, causing negative thoracic pressure in the lungs. This negative pressure can lead to fluid accumulation in the lungs, resulting in pulmonary edema. The obstructed glottis might be caused by laryngospasm, which occurs when the muscles around the larynx involuntarily spasm and can lead to complete upper airway occlusion. This report shares the case of a 33-year-old woman hospitalized for periapical dental abscess, facial swelling, and shortness of breath. The patient exhibited signs of poor oral hygiene. After the exacerbation of her symptoms, she showed signs of asphyxia and decreased oxygen saturation, which led to her intubation. Imaging revealed bilateral pleural effusion and patchy ground glass opacities favoring NPPE. After three days of treatment with diuretics and other conservative measures, her condition was alleviated, and she was extubated. Laryngospasm in the presence of a dental abscess is uncommon. Identification of imaging favoring NPPE in this setting is even more rare. In cases of laryngospasm, prompt intubation is crucial. Therapy with diuretics and other conservative measures can effectively treat NPPE following laryngospasm.

Pulmonary apoplexy following severe mitral valve stenosis: A case report.

Hemoptysis is a common clinical symptom in emergency patients. It is characterized by the discharge of bloody sputum, which originates from the lower respiratory tract. In the majority of cases, this event is self-limiting, and only in less than 5% of cases, it is massive. Mitral valve stenosis is an uncommon cause of hemoptysis, with a prevalence of 4.2%. In rare cases of this condition, massive and sudden hemoptysis occurs, which is called pulmonary apoplexy. Here, a 35-year-old woman with a history of mitral valve stenosis is introduced who was referred to the hospital with a complaint of massive hemoptysis and sudden shortness of breath. According to the history of mitral valve stenosis, the patient was diagnosed with pulmonary apoplexy. After treatment, both the imaging findings and the patient's symptoms resolved within a short period of time. Even though pulmonary apoplexy is often severe, it can still respond well to conservative treatments and may indicate a need for immediate attention to the stenosis of the mitral valve.

Alveolar Microlithiasis with Mild Clinical Symptoms But Severe Imaging Findings: A Case Report.

Pulmonary alveolar microlithiasis (PAM) is a rare genetic disorder that causes calcium phosphate microliths to form in the alveoli. Symptoms usually appear in a person's third or fourth decade of life. A definitive diagnosis does not always demand a lung biopsy but can be achieved in families with more than one member with PAM and compatible chest imaging. We present the case of a 47-year-old woman referred to us for shortness of breath. Chest imaging revealed bilateral diffuse ground-glass opacities, interlobar fissure calcification, and subpleural linear calcifications, leading to a diagnosis of PAM. Although there is no specific treatment for this condition, early diagnosis can help prevent it from progressing rapidly by avoiding exposure to risk factors.

External validation of a cardiovascular risk model for Omani patients with type 2 diabetes mellitus: a retrospective cohort study.

OBJECTIVES: To externally validate a recently developed cardiovascular disease (CVD) risk model for Omanis with type 2 diabetes mellitus (T2DM). DESIGN: Retrospective cohort study. SETTING: Nine primary care centres in Muscat Governorate, Oman. PARTICIPANTS: A total of 809 male and female adult Omani patients with T2DM free of CVD at baseline were selected using a systematic random sampling strategy. OUTCOME MEASURES: Data regarding CVD risk factors and outcomes were collected from the patients' electronic medical records between 29 August 2020 and 2 May 2021. The ability of the model to discriminate CVD risk was assessed by calculating the area under the curve (AUC) of the receiver-operating characteristic curve. Calibration of the model was evaluated using a Hosmer-Lemeshow χ2 test and the Brier score. RESULTS: The incidence of CVD events over the 5-year follow-up period was 4.6%, with myocardial infarction being most frequent (48.6%), followed by peripheral arterial disease (27%) and non-fatal stroke (21.6%). A cut-off risk value of 11.8% demonstrated good sensitivity (67.6%) and specificity (66.5%). The area under the curve (AUC) was 0.7 (95% CI 0.60 to 0.78) and the Brier score was 0.01. However, the overall mean predicted risk was greater than the overall observed risk (11.8% vs 4.6%) and the calibration graph showed a relatively significant difference between predicted and observed risk levels in different subgroups. CONCLUSIONS: Although the model slightly overestimated the CVD risk, it demonstrated good discrimination. Recalibration of the model is required, after which it has the potential to be applied to patients presenting to diabetic care centres elsewhere in Oman.

Epidemiology and prevalence of somatic symptom disorder at the primary care level in Muscat, Oman: A cross-sectional study.

OBJECTIVES: Somatic symptom disorder (SSD) is a diagnostic classification to describe the occurrence of physical symptoms without organic cause. This study aimed to identify prevalence rates and associated characteristics of SSD among adults in primary care settings. METHODS: This cross-sectional study took place between July 2020 and March 2021 and included a random selection of 3383 Omani adults attending 12 primary healthcare centres in Muscat Governorate. Screening was conducted using an Arabic version of the Somatic Symptom Scale-8 (SSS-8). RESULTS: A total of 2000 adults participated in the study (response rate: 67.3%), of which most were female (71.7%) and under 50 years old (86.2%). Based on their SSS-8 scores, 602 participants (17.8%) had SSD, resulting in an overall prevalence estimate of 30.1% (95% confidence interval: 28.13-32.15). Significant associations were observed between SSD and age (p = 0.002), gender (p < 0.001), marital status (p = 0.030) and chronic comorbidities (p = 0.001). In addition, adjusted odds ratio estimates revealed SSD to be significantly associated with gender (p < 0.001), education level (p < 0.001) and chronic comorbidities (p = 0.001). CONCLUSION: The estimated prevalence of SSD in primary care settings is high compared to reports from elsewhere in the Gulf region. There is an urgent need to enhance the diagnosis of SSD at the primary care level in order to reduce healthcare service overutilisation and patient dissatisfaction. Moreover, healthcare practitioners should be aware of the effect of age, gender, educational status and chronic comorbidities on somatic symptoms.

Quality of life and coping strategies used by parents of children with autism spectrum disorder in Oman.

Objective: Raising a child with autism spectrum disorder (ASD) can have a significant impact on quality of life (QOL). This study was conducted to assess the QOL and coping strategies of parents of children with ASD in Oman. Method: This descriptive cross-sectional study was conducted at Al-Masarra psychiatric hospital. Telephone interviews were conducted with the parents of all children diagnosed with ASD and attending Al-Masarra Hospital between January 2018 and October 2021. Data were collected using the Ways of Coping Checklist-Revised and World Health Organization Quality of Life Assessment-Brief. Results: A total of 304 parents participated in the study (response rate: 100%), of which 59.5% were female. The mean age of the parents and children with ASD was 40.4 ± 6.9 and 8.4 ± 2.3 years, respectively. Most children with ASD were male (78.3%) and entirely dependent upon their parents (18.1%). Seeking social support was the most common coping strategy (75.53 ± 13.99), while escape avoidance was the least common (51.78 ± 8.04). Most parents (48.7%) rated their QOL as good to very good, with acceptable scores in the psychological (70.92 ± 11.22) and social (73.27 ± 11.46) domains, borderline in the physical health domain (63.51 ± 7.77), and poor in the environmental domain (58.31 ± 11.00). Conclusions: Omani parents of children with ASD utilize various coping strategies, with coping skills considered a positive index for mental health in general. No significant differences were observed between Omani fathers and mothers in terms of QOL or coping strategies.

Inflammatory Markers as a Predictor of Postmenopausal Osteoporosis: Cross-sectional study from Sultan Qaboos University Hospital.

Objectives: Postmenopausal osteoporosis is a progressive metabolic bone disease resulting from oestrogen deficiency. Due to the silent nature of the disease, there is an urgent need for a simple, early predictive marker. This study aimed to assess the potential of three factors-neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR) and platelet-to-lymphocyte ratio (PLR)-as inflammatory markers of bone mineral density (BMD) loss. Methods: A retrospective cross-sectional study was conducted among 450 postmenopausal Omani women undergoing dual-energy X-ray absorptiometry at the Sultan Qaboos University Hospital, Muscat, Oman, from January 2017 to December 2019. The participants were allocated to groups based on lumbar spine BMD t-score values. A receiver operating characteristic curve was used to determine the area under the curve (AUC). Multivariate logistic regression was performed to identify independent predictors of low BMD. Results: A total of 65 (14.4%), 164 (36.4%) and 221 (49.1%) women were allocated to the control, osteopenia and osteoporosis groups, respectively. No significant differences in PLR, MLR and NLR values were observed among the groups. BMD t-score values were reversely correlated with age (P = 0.007) and PLR (P = 0.004) and positively correlated with body mass index (BMI; P <0.001). The AUC was 0.59. The independent predictors of low BMD were age (>65 years) and BMI (<25 kg/m2). Conclusion: None of the three inflammatory biomarkers studied were found to be useful prognostic indicators of bone loss. Further research is recommended to reject or support theories regarding the role of inflammatory status in the pathogenesis.

Prevalence of Coeliac Disease in Omani Adults with Iron Deficiency Anaemia of Unknown Cause: Case-finding study.

Objectives: This study aimed to estimate the serological prevalence of coeliac disease in patients with iron deficiency anaemia (IDA) of unknown cause at a primary healthcare facility in Oman. Methods: This prospective case-finding study was conducted at the primary care clinics in Sultan Qaboos University Hospital, Muscat, Oman from September 2018 to June 2020. Patients aged 18 to 55 years, with a haemoglobin (Hb) level <11.5 g/dL for males and <11.0 g/dL for females and a ferritin level <30 ng/mL for males and <13 ng/mL for females, were included in the study. Blood samples were obtained for initial serological screening using serum immunoglobulin (Ig)A level; those samples with normal levels of IgA, IgA anti-tissue transglutaminase antibody (tTG) and IgA anti-deamidated gliadin peptide (DGP) were determined. Positive IgA-tTG test was confirmed using IgA-endomysial antibodies. Patients with low IgA levels were tested using IgG-tTG and IgG-DGP. Results: A total of 104 patients participated in this study. Eight patients (7.7%) were found to have a positive serological screening result for coeliac disease; of these patients, three (37.5%) had a positive IgA-tTG result. Two of those three (66.7%) had a positive IgA-endomysial antibody. The IgA-DGP result was positive in seven (6.7%) of the 104 patients. Out of those seven patients, two also had a positive IgA tTG. Conclusion: Coeliac disease is not a rare disorder. There is a need to increase awareness among healthcare professionals about coeliac disease and its non-classical manifestations such as IDA.

Evaluating Trauma Care Capabilities using the Essential Trauma Care Guidelines of the World Health Organization: Cross-sectional study of primary health centres in Muscat, Oman.

Objectives: This study aimed to evaluate trauma care capabilities at the primary care level in Muscat, Oman, using World Health Organization guidelines. Methods: This descriptive cross-sectional study was conducted between January and March 2015 at eight primary health centres in Seeb. An English-language questionnaire was distributed to the medical officer or nurse in-charge at each centre to determine the number of staff, total population being served, number of emergency trauma cases and availability of ambulances. Subsequently, 10 doctors from each health centre were randomly selected to assess the availability of physical resources as well as their trauma skills and knowledge. Results: There were limited physical and human resources for the management of trauma and a complete absence of trauma administrative functions, such as local trauma registries or quality improvement activities. Conclusion: This study highlighted the need to introduce national guidelines and improve the delivery of trauma services in Oman.

Types of Primary Healthcare Emergencies in Muscat, Oman: A retrospective cross-sectional study of five primary care centres.

OBJECTIVES: Emergencies can occur at any time and be life-threatening or cause permanent damage. Accordingly, the management of emergency cases is an integral part of primary healthcare (PHC). This study aimed to estimate the proportion and types of emergency cases presented to PHC centres in Muscat, Oman. METHODS: This retrospective cross-sectional study was conducted from March to August 2016 at five PHC centres in the Muscat Governorate. A total of 800 emergency cases (i.e. those labelled in the health information system as an accident and emergency) of Omani patients aged ≥5 years presented during this period. Every second case, based on arrival to the registration desk, was selected for analysis. Electronic medical records were reviewed to collect data regarding demographic features, presenting complaints, time and season of presentation, management provided and method of transportation if referred to tertiary care. RESULTS: The proportion of emergency cases was <2.5% (range: 1-2.5%). The most common type of emergency was musculoskeletal issues/trauma (34.3%) followed by gastroenterological (15.1%) and genitourinary (10.0%) emergencies. Most patients were either 21-39 or 5-12 years old (35.0% and 21.6%, respectively). The majority (59.6%) were treated directly at the health centre, while the remaining patients (40.4%) were referred to tertiary care. At referral, only 12.1% were transported by ambulance and the rest via private transport. CONCLUSION: Musculoskeletal issues/trauma was the most common type of emergency seen at the selected PHC centres in Muscat. Further research is needed to determine whether PHC centres have the capability and resources necessary to appropriately manage emergency cases.

Prevalence of Cytological Abnormalities in Papanicolaou Smears and Risk Factors for Cervical Cancer Among Women in Muscat, Oman.

OBJECTIVES: This study aimed to estimate the prevalence of cytological abnormalities in Papanicolaou (Pap) smears and related risk factors among Omani women. METHODS: A cross-sectional study was conducted from March to September 2019 at the gynaecology and family medicine clinics of Khoula Hospital and Sultan Qaboos University Hospital in Muscat. All asymptomatic Omani women aged between 21 and 65 years were included. Data regarding the participants' sociodemographic characteristics and known risk factors were collected using a self-reported sheet. Pap smears were performed and the results were reported by a cytotechnologist and histopathologist. RESULTS: A total of 442 women participated in the study (response rate: 100%). The mean age was 39.0 ± 9.7 years old. The prevalence of cervical cytological abnormalities was 3.7%. There was a significant association between human papillomavirus (HPV) infection and cervical cell abnormalities ( P = 0.017); however, there was no link with hormonal contraception use, pregnancy before the age of 17 years or parity (P >0.050 each). CONCLUSION: The prevalence of cervical cell abnormalities in Oman was similar to that observed in Arab countries and relatively low in comparison to findings from Western countries. A screening program should be implemented at the primary care level. The findings of this study also highlighted the need for a future vaccination program against HPV infections.

Factors Associated with Choice of Career in Family Medicine Among Junior Doctors in Oman.

OBJECTIVES: The number of family physicians in Oman is far below that recommended by the World Health Organization. This study aimed to determine factors influencing junior doctors' choice of a career in family medicine. METHODS: This cross-sectional study was conducted between March and June 2018 and targeted applicants to Oman Medical Specialty Board residency programmes during the 2018-2019 academic year. Applicants were grouped according to their choice of either family medicine (n = 64) or other specialities (n = 81). A self-administered questionnaire was utilised to compare the applicants' sociodemographic characteristics, factors influencing their choice of career and their Myers-Briggs Type Indicator® (MBTI) personality traits. RESULTS: A total of 52 family medicine and 43 other residency applicants participated in the study (response rates: 81.3% and 53.1%, respectively). Most family medicine applicants were female (86.5%), married (65.4%) and resided in rural areas (73.1%); moreover, 19.2% were ≥30 years of age. Overall, emphasis on continuity of care, opportunity to deal with a variety of medical problems, the ability to use a wide range of skills and knowledge, early exposure to the discipline, opportunity to teach and perform research and the influence of family or friends were important factors in determining choice of a career in family medicine. Moreover, the MBTI analysis revealed that family medicine applicants were commonly extroverted-sensing-thinking-judging personality types. CONCLUSION: Knowledge of the factors influencing career choice among junior doctors may be useful in determining future admission policies in order to increase the number of family physicians in Oman.

The Psychological Impact of Referral for Mammography Screening for Breast Cancer Among Women in Muscat Governorate: A cross-sectional study.

OBJECTIVES: Breast cancer constitutes the majority of diagnosed cancers in Oman's females, accounting for 19.2%, which prompted the introduction of a breast cancer screening programme into the Omani healthcare system. There are rising international concerns about the effectiveness of mammography as a screening tool and its psychological impact. The current study aimed to determine the social, emotional and physical dysfunction caused by the waiting time from the day of scheduling the appointment until the day of screening and explore associated risk factors. METHODS: This cross-sectional study was conducted between March and December 2017 at Khoula Hospital, Muscat, Oman, using a two-part self-administered questionnaire. Part one of the questionnaire collected clinical and demographic data. Part two consisted of the Psychological Consequences Questionnaire (PCQ) and focused on psychological consequences, measuring the effect of mammographic screening on emotional, physical and social functions. RESULTS: A total of 300 women aged ≥40 years old participated in this study (response rate: 100%). Results revealed that there was a minimal negative psychological impact from screening using mammograms. All PCQ domains were significantly impacted for participants who reported a family history of cancer (P = 0.007). The social score was significantly higher among women between 40-50 years old (P = 0.008). Scores of emotional and social functions were significantly affected by participants' employment status; employed women were more affected than those who were not (P = 0.043 and 0.012, respectively). However, women's levels of literacy did not affect any of the domains. CONCLUSION: The psychosocial impact of the waiting period between scheduling and undergoing mammography screening was minimal in the current sample. Future research should evaluate the psychosocial impact on patients at different recall times.
