Effect of Transplanted Bone Marrow on Spleen of Irradiated Pregnant Rats and Their Fetuses.

<b>Background and Objective:</b> Prenatal ionizing radiation exposure may hinder fetal and embryonic growth depending on the dose and gestational age. The current study's objective was to discover how bone marrow transplants affected the spleens of pregnant rats that had been subjected to γ (Gamma) radiation. <b>Materials and Methods:</b> Sixty rats that were pregnant were separated into five different groups, each with 6 females. The pregnant rats in the second Group were exposed to 2Gy of γ-rays. Group III; pregnant rats subjected to 2Gy of γ-rays, followed by an intraperitoneal injection of newly prepared bone marrow transplantation (BMT). The fifth Group were exposed to 2Gy γ-rays and received 1 dosage of BMT an hour later. Spleen samples from the pregnant rats as well as their fetuses were taken for histological and histochemical analyses. <b>Results:</b> Gamma rays damaged the splenic tissue of women and their fetuses on days 7 or 14 of pregnancy in a variety of histological and histochemical ways, although bone marrow transplantation significantly reduced the damage. Treated mothers with bone marrow post-radiation showed a noticeable recovery in spleen of their fetuses. Improved spleen architecture was accompanied by appearance of normal content of collagen, polysaccharides and total protein in the fetal spleen tissue especially on day 7 of gestation. <b>Conclusion:</b> Bone marrow transplantation can lessen the damage caused by gamma radiation.

Pharmacists' Attitudes Towards Long-Term Use of Nasal Decongestants: A Cross-Sectional Study.

Background: Rhinitis medicamentosa is a nonallergic inflammation of the nasal mucosa caused by topical decongestants overuse. It mainly affects young and middle-aged adults. Therefore, the aim of this study was to investigate the attitudes of pharmacists regarding the utilization of over-the-counter intranasal decongestants. Methods: An online cross-sectional study was conducted from November 2021 to January 2022. The target population of the study included pharmacists who work in community pharmacies in Saudi Arabia. Binary logistic regression analysis was used to identify predictors of having positive attitude towards controlling the use of decongestant. Results: A total of 220 participants were included in this study. Around 15.0% of them reported that ND come with a physician prescription. The majority of the participants (87.3%) reported that the less than 5 days is the maximum safe duration for the use of NDs. Overall, the study participants demonstrated moderately positive attitude towards controlling the use of decongestant with a mean attitude score of 2.5 (standard deviation: 1.2) out of 5; which represents 50.0% of the maximum score. Binary logistic regression analysis identified that pharmacists aged 31-40 years were two-folds more likely to have positive attitude towards controlling the use of decongestant compared to others (p<0.05). Around 45.9% of them reported that they recommend other over-the-counter treatments like nasal irrigation, nasal steroids, or antihistamine if they see a patient with RM asking for ND with or without prescription. Conclusion: The majority of pharmacists in Saudi Arabia demonstrated sufficient awareness and understanding on the adverse effects associated with the excessive use of NDs. Rhinitis medicamentosa can be avoided by appropriate measures, highlighting the importance of raising awareness about the excessive use of decongestants among healthcare professionals and patients alike.

Incidental detection of paranasal sinuses abnormalities on CT imaging of the head in Saudi adult population.

The paranasal sinuses are hollowed, air-filled cavities surrounding the nasal cavity. Many pathological processes affect the sinuses, but inflammatory conditions are the commonest, even in asymptomatic patients who undergo head imaging for other indications showing one or more abnormalities of the sinuses. Our research aims to determine the prevalence of incidental paranasal sinuses abnormalities seen among patients who undergo head CT scanning. In addition, it provides baseline information for further investigations required. The study was designed to evaluate all patients who underwent head CT scanning for any reason unrelated to paranasal sinuses abnormalities. 1849 cases were selected and retrospectively analyzed from the elective and emergency CT in the last nine months, from August 2020 to April 2021. In order to meet the inclusion criteria, indications for imaging must not be sinus-related. The study was conducted on 1849 cases who had undergone head CT scans for pathology, 1204 (65%) were male and 645 (35%) were female. Abnormalities of the sinuses were found in about 617 (33%) of all patients, with a higher rate in males (22.23%) than females (11.14%). In addition, these abnormalities were found in younger patients at a higher rate than in middle and old ages 19.74%, 7.19%, and 6.44%, respectively. Our findings revealed that the prevalence of paranasal sinuses abnormalities in asymptomatic Saudi patients was high (33%). Most of the affected sinuses were the maxillary. The male patients were more affected than females in all findings.

Is there a misuse of computed tomography in the diagnostic workup of headache? A retrospective record-based study in secondary health-care facility in Saudi Arabia.

INTRODUCTION: Headache disorders are one of the most prevalent global public-health problems that require placing high demand on health-care Services. Since it is one of the most frequent complaints in clinical practice worldwide, it causes a considerable burden in terms of the social cost. The study aimed to give a guide for the decision on the utilization of computed tomography (CT) in the diagnostic workup and identify if patients require neurological imaging (CT) for proper diagnosis or not. MATERIALS AND METHODS: The study was carried out in the Radiology Department in King Khalid Hospital, Al Kharj, Saudi Arabia from October 15, 2016, to February 15, 2017. A retrospective record-based study conducted using the documented CT reports in the files of patients whom were referred to the radiology department complaining of any type of a headache. RESULTS: The data included 210 patients 51% were males and 49% were females. The patients were distributed into age groups; the mean age was 38.46 standard deviation ± 13.56. Among Saudi population, the etiology of headache was varying; the most prevalent type of headache was tension headache 25.71% of the total headache patients followed by cluster 25.24% and the migraine with the lowest proportionality. The majority of the patients' headache pain was mild 60%. Moreover, the CT reports for most of the patients were normal. Spearman Correlation test was used to see if there is a significance in using the CT for any patient who comes with symptoms including headache, and the results have shown that there is no association and clinical significance in using the CT for patients with headache without suspecting other clinical condition (P = 0.177). CONCLUSION: Headache disorders must be on the public-health agenda. Tension, migraine, and cluster-type headaches represent the majority of primary headaches. Statistically no significance or need to obtain CT if there are no life-threatening conditions expected or trauma presented.

Prenylbicyclogermacrane diterpenoids from the formosan soft coral Nephthea elongata.

Seven new prenylbicyclogermacrane diterpenoids, pacificins K--Q (1--7), were isolated from the methylene chloride solubles of the Formosan soft coral Nephthea elongata. Their structures were elucidated by extensive spectroscopic analysis and their cytotoxicity against selected cancer cells was measured in vitro.
