When managing coronavirus disease 2019 (COVID-19) patients, radiological imaging complements clinical evaluation and laboratory parameters. We aimed to assess the sensitivity of chest radiography findings in detecting COVID-19, describe those findings, and assess the association of positive chest radiography findings with clinical and laboratory findings. A multicentre, cross-sectional study was conducted involving all primary health care corporation-registered patients (2485 patients) enrolled over a 1-month period during the peak of the 2020 pandemic wave in Qatar. These patients had reverse transcription-polymerase chain reaction-confirmed COVID-19 and underwent chest radiography within 72 hours of the swab test. A positive result on reverse transcription-polymerase chain reaction was the gold standard for diagnosing COVID-19. The sensitivity of chest radiography was calculated. The airspace opacities were mostly distributed in the peripheral and lower lung zones, and most of the patients had bilateral involvement. Pleural effusion was detected in some cases. The risk of having positive chest X-ray findings increased with age, Southeast Asian nationality, fever, or a history of fever and diarrhoea. Patients with cardiac disease, obesity, hypertension, diabetes, and chronic kidney disease were at a higher risk of having positive chest X-ray findings. There was a statistically significant increase in the mean serum albumin, white blood cell count, neutrophil count, and serum C-reactive protein, hepatic enzymes, and total bilirubin with an increase in the radiographic severity score.
Background: Gallbladder (GB) polyps are raised lesions from the GB wall and projected into its lumen. The prevalence of GB polyps ranged between 4.3% and 12.3%. The clinical presentation of GB polypoid lesions vary, can be nonspecific and vague, and may be asymptomatic. Identifying malignant and premalignant polyps is important to provide treatment early and prevent cancer spread or development of malignancy. Ultrasonography (US) is the first imaging modality widely used in abdominal imaging. It is a noninvasive, rapid, painless, and safe imaging technique, with no radiation; thus, it is considered the best available examination with good sensitivity and specificity for GB polyps. Aim of the work: This study aimed to determine the relative frequency of the GB polyps and its risk factors among patients who underwent abdominal US in Primary Health Care Corporation, Qatar. Materials and methods: This was quantitative multicenter observational case–control study nested in a cross-sectional design. For the cross-sectional top-level study, the first step was to assess available abdominal ultrasound studies for the presence of GB polyps and stones. The second step was to perform a case–control study with three groups (a case group and two control groups; first, participants without GB stones and GB polyps; second, patients with GB stones but without GB polyps). Results: The study evaluated the GB images of 7156 individuals. The overall prevalence of GB polyps was 7.4% in the study population. Specifically, the overall prevalence of solitary GB polyp was 4.2% and that of multiple GB polyps was 3.2%. Regarding the size distribution of GB polyps in positive cases, 89.4% were < 6 mm, 9.3% were 69 mm, and 1.3% were ≥ 10 mm. Prevalence rate of selected comorbidities were as follows: liver disease, 1.8%; diabetes mellitus, 25.5%; hypertension, 25.5%; and dyslipidemia, 29.8%. The prevalence in male and female patients was 7.7% and 7%, respectively. The prevalence of GB polyps was higher in south-eastern patients (21.4% of positive cases) and was the highest in the overweight group (8.8%). A higher prevalence was noted in the hypertensive group (hypertensive group, 9.8%; non-hypertensive group, 6.6%) and dyslipidemia group (dyslipidemia group, 7.8%; no dyslipidemia group, 7.2%). Moreover, a higher prevalence was noted in hepatitis B surface (HBS)-positive group (15%) than in the HBS-negative group (8.2%) and slightly higher in Helicobacter pylori antigen positive group than in the negative group. Conclusion: Abdominal US is an important and commonly used imaging modality in the detection of GB polyps. In this study, the prevalence of GB polyps was approximately 7.4%, with higher prevalence in participants who were overweight and had diabetes mellitus, hypertension, and dyslipidemia.
Xanthogranulomatous cholecystitis is a benign, uncommon type of chronic cholecystitis manifested by focal or diffuse severe inflammatory process of the gallbladder (GB). It is inflammatory disease of the gallbladder characterized by the infiltrations of plasma cells, lipid-laden histiocytes, and the fibroblasts proliferation in GB wall. Gallstones are present in all patients, and like most symptomatic gallbladder diseases, there is a female predominance. It is an active inflammatory process which could leads to significant morbidity. The term Xanthogranulomatous cholecystitis was initially proposed by Goodman and Ishak in 1981. The pathogenesis of XGC is the rupture of Rokitansky-Aschoff sinuses and extravasation of bile into the muscular layer. The rupture of the serosa results in adhesion to the adjacent liver, duodenum, and transverse colon. Macroscopically, it appears like yellowish masses in the wall of the GB. Radiologically it is an important mimic of gallbladder carcinoma.
Background and study aim: PCOS is a common recognized, heterogeneous disorder affecting women throughout their lifetime and it shows an excess production of androgens hor¬mone, ovulatory dysfunction and polycystic changes of the ovaries which can be seen by ultrasonography. Ultrasound is the first imaging modality widely used in pelvic imaging. It is a non-invasive, rapid, painless, and safe imaging technique with no radiation. The aim of this study is to estimate the prevalence and ultrasound features of PCOS among young females. Patients and Methods: A Multi-center retrospective descriptive electronic record-based study for all subjects with a valid ultrasound of the ovaries done in PHCC health centers from 1 January 2021 to 31 December 2021. The available pelvic ultrasound images were assessed for presence of PCOS sonographic criteria. Prevalence of PCO was calculated. The sonographic features of PCO were described. Results: The current study showed prevalence of PCO among young female with age ranging from 15 to 35 years, to be 6.85% with the majority of cases being bilateral. While unilateral cases were more in the right ovary. Cases with PCO peripheral follicular arrangement were found to be the highest described sonographic finding in PCO cases. Conclusion: Ultrasound plays a major role in PCO diagnosis. The assessment of the ovaries has been greatly improved by sonographic diagnostic criteria of PCO. In addition to demonstration of ovarian size, ultrasonography can evaluate the characteristic patterns of follicles distribution and ovarian stromal changes. Key Words: Prevalence, PCO, US, Pelvis, Qatar.
