Background: Thyroid cancer (TC) is becoming more prevalent in Saudi Arabia, currently ranking among the top three cancers affecting women. Despite its rising prevalence, there has been limited assessment of the factors influencing the survival rate (SR) among the Saudi population over an extended period. Therefore, this study aims to address this critical gap in knowledge by identifying the factors affecting the SR of TC, comparing the SR with previous studies, and exploring potential areas for improving the SR of patients.

Methods: A retrospective study analyzed secondary data from patients diagnosed with TC, as recorded in the King Abdulaziz Medical City Cancer Registry in Riyadh, Saudi Arabia, over 10 years from 2009 to 2018.

Results: Of the total 665 TC cases, the mean age at diagnosis was 46.2 years (±SD 16), and most patients were women (78.5%), with the majority being under 50 years old. The most common type of cancer was papillary thyroid carcinoma, comprising 88.6% of all TCs. Over half of the cases were localized to one of the lobes of the thyroid gland, with almost equal frequency between the two lobes. The 5-year SR of localized papillary thyroid carcinoma reached 96.5%, in contrast to the extremely low SR of anaplastic thyroid carcinoma, where most patients died within a few months of the diagnosis. Factors such as morphology, tumor extension, male gender, and age at diagnosis significantly impacted patient survival, as analyzed by the Kaplan–Meier test (p < 0.001). Compared to other types of cancer, those with anaplastic thyroid carcinoma had a lower SR.

Conclusion: The SR of TC patients is predicted by factors such as their age, morphological type, and the presence of distant metastasis.

Background: Patients recovering from severe COVID-19 infections have experienced prolonged cognitive, physical, and psychological sequelae, including cardiorespiratory and motor deconditioning, neurological deterioration, anxiety, and depression. The impact of rehabilitation post-acute COVID-19 infection was recognized in the literature, but studies assessing and quantifying specific functional outcomes were lacking. This study aims to describe the characteristics and quantify the changes in functional outcomes of patients admitted to Qatar Rehabilitation Institute (QRI) for inpatient rehabilitation (IPR) post-COVID-19 infection during a 10-month period in 2021.

Methods: This is a retrospective observational cohort study, which included individuals over 18 years of age with a documented COVID-19-positive diagnosis who were admitted to QRI for IPR due to COVID-19 complications. Data was collected by the investigators from January 1, 2021, until October 30, 2021. A total of 243 patients were included in this study. The changes in functional rehabilitation outcomes were assessed and quantified at both the patient’s baseline (on admission to QRI) and after completion of IPR (on discharge). The duration of the IPR program varied based on each patient’s baseline assessment. Patients were given a total of 8–12 weeks to achieve their rehabilitation goals and were discharged once those goals were met. Several validated tools were utilized in this study including Functional Independence Measure (FIM), Berg Balance Scale (BBS), Dynamic Gait Index (DGI), Modified Medical Research Council (mMRC) Dyspnea Scale, Mini-Mental State Examination (MMSE), and Right- and left-Hand Grip Strength. In addition, patients’ diet, the need for respiratory support, and the presence of a tracheostomy tube before and after IPR were also recorded.

Results: In total, 84.4% of the included patients were males (n = 205); with a mean age of 52.44 ± 12.99 years. The most commonly reported comorbidities were type 2 diabetes (62.1%) and hypertension (49.8%) with 83.5% of patients experiencing critical illness neuromyopathy. The average patients’ length of stay in QRI was 33.92 ± 27.72 days. A statistically significant improvement in all functional outcome scales was noted following the completion of the IPR program (p = 0.001). The number of patients requiring modification to their diet or feeding via nasogastric tube (NGT) significantly decreased by 35% and 93%, respectively (p = 0.001). Patients requiring respiratory support decreased by 98% (p = 0.001) and the need for a tracheostomy tube among patients was reduced by 95% (p = 0.001).

Conclusion: IPR following COVID-19 infection was associated with significant functional, motor, and cardiorespiratory improvement. Dedicating clinics for post-COVID-19 rehabilitation would ensure improved patient outcomes and enhanced recovery.

Background: The incidence of hepatic abnormalities has been notably higher following the coronavirus disease 2019 (COVID-19) infection, attributed to the virus’s entry into cells via angiotensin-converting enzyme 2 (ACE2) surface expression. The gastrointestinal tract’s significant ACE2 expression, alongside a lesser degree in the biliary epithelium, has been implicated in gastrointestinal symptoms and liver injury.

Purpose: The aim of this study was to determine whether specific ultrasonographic findings in the liver correlate with acute increases in liver function tests (LFTs) among hospitalized patients.

Methods: A retrospective analysis was conducted on hospitalized COVID-19 patients at Hazem Mebaireek General Hospital in Qatar, from March 1, 2020, to June 30, 2020. The study focused on patients who experienced acute increases in LFTs, excluding those with chronic liver disease. Ultrasound imaging and patient records were reviewed to gather data.

Results: Out of 223 ultrasound studies of COVID-19 patients, 158 met the inclusion criteria. The majority were male, with a mean age of 47.76 ± 13.76 years. Ultrasound results showed 43.7% normal liver parenchyma, while 56.3% exhibited nonspecific abnormalities such as diffuse liver hyperechogenicity (39.2%), enlargement with diffuse hyperechogenicity (12.7%), and other findings (4.4%). The biliary tree was predominantly normal (96.2%), with 3.8% showing abnormalities, including intrahepatic (2.5%) and extrahepatic (1.3%) dilatation. Gallbladder evaluations were normal in 60.1% of cases, with 39.9% showing abnormalities like stones (6.3%), stones with sludge (13.3%), polyps (6.3%), wall thickening (1.9%), and other conditions (12%). A significant correlation was found between abnormal liver parenchyma findings and elevated levels of bilirubin (total and direct) and alkaline phosphatase, with p-values < 0.05. Only aspartate aminotransferase levels showed a significant correlation with biliary tree abnormalities.

Conclusion: The most common ultrasonographic finding associated with acute increases in LFTs among hospitalized COVID-19 patients was diffuse liver hyperechogenicity, with or without enlargement. These findings suggest a nonspecific yet significant association with liver function anomalies in the context of COVID-19.

Background: Mature cystic teratomas, also known as dermoid cysts, are the most prevalent form of ovarian germ cell tumors. While they typically manifest in women of reproductive age, they can also occur in pediatric patients. These tumors are generally benign and comprise a diverse array of tissue types. However, large lesions, particularly those exceeding 10 cm in diameter, are infrequent and can present diagnostic and therapeutic challenges. Notably, elevated tumor markers, such as cancer antigen 19-9 (CA 19-9), are not commonly associated with mature cystic teratomas, rendering this case particularly unusual.

Case presentation: The clinical case involved an 8-year-old female patient who presented with an exceptionally large ovarian teratoma, measuring 13 × 12 cm. While the prepubertal presentation of such tumors is not uncommon, the remarkable size of the lesion was an extraordinary occurrence. Preoperative evaluation revealed markedly elevated levels of CA 19-9, a tumor marker, at 297 U/mL—an atypical finding for mature cystic teratomas. Imaging studies identified a complex cystic adnexal mass, indicative of a teratoma. Consequently, a laparotomy was performed, revealing an intact, benign lesion that was successfully resected via cystectomy, with preservation of the ovary. Histopathological examination confirmed the diagnosis of a mature cystic teratoma, without any evidence of malignant transformation. Notably, following the surgical intervention, the elevated CA 19-9 levels normalized, suggesting a potential association between the teratoma and the abnormal tumor marker levels.

Discussion: This report delineates the surgical management and clinical course of an exceptionally large ovarian teratoma in a pediatric patient with abnormal preoperative tumor markers. Despite atypical features, the excellent prognosis following fertility-sparing resection underscores the significance of conservative treatment in young females.

Conclusion: This case highlights the occurrence of a large mature cystic teratoma with elevated CA-19-9 in a pediatric patient with no complications such as torsion, rupture, or malignancy. The elevation in CA-19-9 likely relates directly to the teratoma itself. A conservative, fertility-sparing surgical approach proved effective, emphasizing the importance of careful preoperative evaluation and management in similar cases.

Background: Perioperative stroke, defined as a stroke occurring within 30 days post-surgery, typically emerges within the first week. The incidence of perioperative stroke among adults undergoing non-cardiac and non-neurological surgeries ranges from 0.1% to 1% after a surgical intervention. Mortality rates following perioperative stroke surge, reaching up to eight times higher than controls, with approximately one in four cases resulting in death. Fortunately, various strategies are available to potentially prevent perioperative strokes. However, the vast amount of data poses challenges for physicians in memorization and recall for clinical use. This study aims to summarize essential perioperative stroke prevention strategies and determine an effective mnemonic for their memorization and recall.

Method: The initial search in PubMed focused solely on review articles published within the last 10 years. It utilized the keywords “perioperative stroke” and “prevention.”

Results: An initial search found 39 articles, with two suitable for review. Using data from selected review articles, further searches were conducted on Google Scholar and PubMed for articles from 2000 to 2024, identifying 30 additional suitable references. From these 32 articles, the author developed a mnemonic, “DAANISH,” to aid in remembering strategies for preventing perioperative stroke.

Conclusion: Implementing this mnemonic may help reduce the risk of perioperative stroke and improve patient outcomes. Future research is needed to confirm its effectiveness.

Introduction: Asthma is a common noncommunicable disease with public health implications due to the rising number of cases among the pediatric population in Qatar.

Aim: The objective of the current study is to explore possible risk factors and associations in relation to pediatric asthma, allergic rhinitis, and eczema cases in Qatar.

Methods: Using the Global Asthma Network questionnaires, this study sampled 2646 children, of which 1210 were aged 6–7 years and 1436 were aged 13–14 years in addition to 3831 adult parents or guardians. The STROBE guidelines were used to ensure the reporting of this cross-sectional study. Univariate and multivariate logistic regression were used to produce the odds ratio for the various risk factors and associated factors, respectively. Multiple associations and risk factors for each of the three diseases were reported.

Results: Based on the outcome of a multivariate logistic regression, being born in Qatar was the only risk factor present across all three diseases. Being male, wheezing ever, wheezing after exercise, and having eczema were other risk factors reported for asthma. Being in the older age group, wheezing ever, and having hay fever were other risk factors reported for allergic rhinitis.

Conclusion: The study concluded that further evaluation into associated and risk factors for asthma, allergic rhinitis, and eczema is warranted in the future.
