RESUMO
OBJECTIVE: To investigate a correlation between birth by caesarean section and autism spectrum disorder (ASD). METHODS: A case-control study with a case to control ratio of 1:2 was performed in Al-Madina Al-Munawarah city, Kingdom of Saudi Arabia during the year 2016. The cases were selected according to the eligibility criteria and children attending a well-baby clinic in the same hospital, were chosen as the control group subjects. Data was collected from the medical records and an interview-based questionnaire was administered to the mothers. The chi-square test was used for bivariate analysis and logistic regression to estimate the crude and adjusted odds ratios (ORs). RESULTS: Eighty-seven cases of ASD and 174 control group subjects were included in the current study. Approximately 39% (n=34) of the 87 children with ASD were delivered by cesarean section compared to 21% (n=36) of the 174 children in the control group. After adjusting for potentially confounding factors, the adjusted OR was 2.9 (95% confidence interval [CI]: 1.57-5.35). CONCLUSION: An association between delivery by cesarean section and ASD was found in this study, in support of the findings of other studies. It is recommended that preventive measures are adopted to avoid unnecessary cesarean sections.

In the current study, we enrolled 14 Egyptian infertile males with isolated congenital bilateral absence of the vas deferens (CBAVD). Screening for the most commonly reported 36 CFTR mutations, and the intron 8 (T)n splice variant was performed by multiplex PCR followed by reversed hybridisation. Samples with the 5T variant were picked for DNA sequencing of intron 8/exon 9 region to identify the number of adjacent TG repeats. The p.Phe508del and the p.Ser1251Asn mutations were detected in heterozygous state in three patients (10.7% of alleles) and in one patient (3.6% of alleles), respectively, while the 5T variant was detected in five patients (28.6% of alleles). Among those five patients, four had TG12 repeats and one had TG13 repeats confirming the pathogenic penetrance of all 5T alleles in Egyptian CBAVD patients. The allelic frequencies of the mutations p.Phe508del, p.Ser1251Asn and the 5T variant in 60 Egyptian cystic fibrosis patients were 24.2%, 3.3% and 2.5% respectively. The mutation p.Ser1251Asn was detected for the first time in isolated CBAVD patient in our study. Due to the high prevalence of p.Phe508del mutation and 5T variant in Egyptian CBAVD patients, we recommend their screening initially, ideally followed by full CFTR gene sequencing in unidentified patients.

This study aimed to assess glutathione-S-transferase (GST) enzyme- oxidative stress (OS) relationship in the internal spermatic vein (ISV) of infertile men associated with varicocele (Vx). Ninety five infertile oligoasthenoteratozoospemic (OAT) men associated with Vx were subjected to history taking, clinical examination and semen analysis. During inguinal varicocelectomy, GST, malondialdehyde (MDA) and glutathione peroxidase (GPx) were estimated in the blood samples drawn from ISV and median cubital veins. The mean levels of GST, GPx were significantly decreased and the mean level of GPx was significantly increased in the ISV compared with the peripheral blood. The mean level of GST and GPx in the ISV was significantly decreased, and the mean level of MDA was significantly increased in Vx grade III compared with Vx grade II cases. There was nonsignificant difference in the mean level of GST in the ISV in unilateral Vx cases compared with bilateral Vx cases. There was significant positive correlation of GST with sperm count, sperm motility, GPx and significant negative correlation with sperm abnormal forms, MDA. It is concluded that ISV of infertile men associated with Vx has decreased levels of GST compared with peripheral venous circulation that is correlated with both OS and Vx grade.

BACKGROUND: Paracetamol is widely used to treat postoperative pain and is well known for its morphine-sparing effect. Therefore, the effect of morphine-paracetamol combination can be synergistic, additive, or infra-additive. The primary aim of our study is to define the median effective analgesic doses (ED50s) of paracetamol, morphine, and the combination of both. Also, the nature of the interaction for postoperative pain after moderately painful surgery using an up-and-down method and isobolographic analysis was determined. METHODS: Ninety patients, undergoing moderately painful surgery, were included in one of the three groups. Determination of the median ED50s was performed by the Dixon and Mood up-and-down method. Initial doses were 1.5 g and 5 mg, with dose adjustment intervals of 0.5 g and 1 mg, in the paracetamol and morphine groups, respectively. The initial doses of paracetamol and morphine were 1.5 g and 3 mg, in the paracetamol-morphine combination group with dose adjustment intervals of 0.25 g for paracetamol and 0.5 mg for morphine. Analgesic efficacy was defined as a reduction to or <3 on a 0-10 numeric rating scale, 45 min after the beginning of drug administration. Isobolographic analysis was used to define the nature of their interaction. RESULTS: The median ED50s of paracetamol and morphine were 2.1 g and 5 mg, respectively. The median ED50 of the combination was 1.3 g for paracetamol and 2.7 mg for morphine. CONCLUSIONS: Our study showed that the combination of the paracetamol and morphine produces an additive analgesic effect. Clinical trial registration NCT01366313.

Monkeypox is a zoonotic disease caused by an enveloped single-stranded DNA virus that belongs to the Poxviridae family. It was first identified in humans in the 1970s. In 2022, a monkeypox outbreak spread extensively outside of endemic countries. Monkeypox infection begins with the prodromal symptoms of fever, myalgia, and lethargy, followed by the development of a characteristic maculopapular rash. In most cases, the illness is self-limiting. However, severe cases can lead to devastating neurological complications, such as encephalitis. Here, we present the case of a 31-year-old male patient with monkeypox who developed encephalomyelitis and exhibited complete neurological recovery upon treatment with pulse steroid and intravenous immunoglobulin.
RESUMO
BACKGROUND: Botulism has not been previously reported in the Kingdom of Saudi Arabia. This rare and sometimes fatal foodborne illness is caused by neurotoxins and primarily results from consuming home-canned fruits, vegetables, dairy, and seafood products & it can lead to paralysis. OBJECTIVE: The purpose of this study was to evaluate the clinical features of patients who developed botulism in Riyadh in 2024 after consuming mayonnaise from a well-known local chain of restaurants in Riyadh, Saudi Arabia. METHODS: We conducted a retrospective analysis of medical records and interviewed patients or their attendants for all hospitalized cases of foodborne botulism at Riyadh First Health Cluster. For each patient, a standard case report form was completed, containing information on demographics, clinical aspects, botulinum test results, and type of exposure. Descriptive statistics were applied to assess the data. During the outbreak, nineteen patients with foodborne diseases were admitted to Riyadh First Health Cluster Hospitals. Following thorough physical examinations, botulism was suspected in each case. RESULTS: Eight of the 19 suspected foodborne illness patients fully satisfied the botulism case definition requirements set forth by the Saudi Arabian Public Health Authority (Weqaya). Among these eight patients, 2 (25%) were male and 6 (75%) were female, with a mean age of 23.25 ± 9.29 years (range: 12-38 years). The incubation period for our patients was 36.25 ± 26.26 h. Notable symptoms included dysphagia in all eight patients (100%), dysarthria, generalized weakness, nausea and vomiting in seven patients (88%), diplopia in four patients (50%), and stomach discomfort in three patients (38%). Of the eight cases, six required intubation, one mimicked brain death, and two were stable. The presence of Clostridium botulinum spores as the cause of the outbreak was confirmed by detecting botulinum spores in contaminated food. CONCLUSION: Diplopia and dysarthria were the most common early sign of botulism. Early manifestations may include respiratory symptoms without any musculoskeletal symptoms. or nausea, vomiting and disorientation.
RESUMO
BACKGROUND: Morbid obesity is associated with important differences in pharmacokinetics and pharmacodynamics. The aim of this study was to determine minimum alveolar concentration of sevoflurane for maintaining bispectral index (BIS) below 50 (MACBIS50 ) in morbidly obese patients undergoing bariatric surgery using the Continual Reassessment Method (CRM) method. METHODS: Twenty-four morbidly obese patients (body mass index 40-70 kg/m(2) ) were enrolled in our study. Twenty minutes following pre-medication with fentanyl 100 µg, general anaesthesia was induced using propofol 2 mg/kg and cisatracurium 2 mg/kg to facilitate tracheal intubation. The lowest BIS score was recorded following induction. Thereafter, when BIS began to increase > 60, maintenance of anaesthesia was started with a pre-determined end-tidal sevoflurane concentration (ET Sevo) and maintained for 10 min followed by 1-min assessment of BIS taken at 10-s intervals to determine the ET Sevo. The ET Sevo leading to a probability close to 80% success was calculated using the CRM, and the MACBIS50 leading to 50% success was calculated by fitting the data to a dose-probability sigmoid curve, respectively. RESULTS: The ET Sevo able to maintain BIS value below 50 was 1.8% in 67% [95% confidence interval (CI) 0.44-0.86] and higher in the remaining 33% of the patients and the ET Sevo leading to a BIS value below 50 in 50% of the patients (MACBIS50 ) was 1.6 ± 0.10%. CONCLUSIONS: The calculated values (1.8% and 1.6%) were higher than that previously reported in normal adult patients (0.97%; 95% CI 0.89-1.1%) and less than that reported in children (2.8%; 95% CI 2.7-3.1%).

INTRODUCTION: Patients with Non-English Language Preferences (NELP) experience challenges navigating the US healthcare system which can lead to disparate outcomes. This study sought to investigate injury patterns and outcomes in hospitalized trauma patients with NELP. METHODS: A retrospective review was performed at a trauma center from January 2019-December 2020. An institutional database of all emergency department video consultations for interpreter services was cross-referenced with the trauma registry and comparisons were made between NELP and English-preferred (EP) speaking patients. RESULTS: During the study, 257 NELP patients were hospitalized after traumatic injury. Twenty-two percent had work related injuries compared to only 3.0% in the EP cohort (p < 0.001). When propensity score matched, there were no significant differences in ICU and hospital length of stay or mortality between NELP and EP patients. DISCUSSION: Trauma patients are linguistically diverse and understanding their injury patterns and outcomes is crucial for guiding culturally and linguistically appropriate injury prevention.

Introduction/Background: The disruption caused due to corona virus disease-2019 (Covid-19) has affected the overall health care delivery worldwide. The elective services were foremost to face the restrictions and closure, subsequently they were resumed only after adoption on newer protocols. Aims: We aimed to estimate the effect of COVID-19 restrictions on operative room utilization. Methodology: This is a retrospective descriptive study. The surgical volume indicators were calculated and a comparison was made between pre-COVID-19 (April-June 2019) and COVID-19 phase (April-June, 2020). Pre-operative covid assessment through the RT-PCR test among the cases waiting for elective surgeries. Results: Overall surgical volume decreased by 53%, which included 87% decrease in elective procedures and 8% decrease in emergency procedures. The overall OR utilization reduced by 63%. Highest reduction in the surgical volume was noted in bariatric surgery (no surgeries conducted in the COVID-19 phase), ophthalmology (99% reduction), and Ear, Nose and Throat surgery (ENT) surgery (92% reduction). Six patients tested positive for pre-operative RT-PCR from the sample of 261 cases posted for elective surgery during resumption phase of elective services, thereby giving the positivity rate of about 2.2%. Conclusion: We found a high level of reduction in the operating room utilization in a secondary care public sector hospital. The pre-operative assessment has enabled to find out the COVID-19 cases and hence preventing the unwanted spread of infection during the surgical procedures.
RESUMO
The patient was a 39-year-old pregnant woman who was scheduled for cesarean section. Spinal anesthesia was induced using a 26-gauge needle with an atraumatic bevel. Postoperatively, the patient developed cranial subdural hematoma manifesting as severe non-postural headache, associated with right eye tearing, fifth cranial nerve palsy and left hemiparesis. The diagnosis was confirmed by computed tomography scan. The patient was managed by careful neurological follow-up associated with conservative treatment and recovered fully after 12 weeks. Our report reviews the literature on 46 patients who developed a postdural puncture headache complicated by subdural hematoma following spinal or epidural anesthesia. It is possible that postdural puncture headache left untreated may be complicated by the development of subdural hematoma. Patients developing a postdural puncture headache unrelieved by conservative measures, as well as the change from postural to non-postural, require careful follow-up for early diagnosis and management of possible subdural hematoma.
RESUMO
Fedratinib hydrochloride is a selective Janus kinase 2 (JAK2) inhibitor approved by the U.S. Food and Drug Administration (FDA) in August 2019 for intermediate- 2 or high-risk primary or secondary myelofibrosis. The approval of this novel oral agent was based on the phase II and III JAKARTA-2 and JAKARTA trials, which both showed significant reduction in splenomegaly and myelofibrosis symptom burden. The most common adverse effects associated with fedratinib include anemia, gastrointestinal symptoms and elevation in liver transaminases. Early clinical trial data was concerning for an increased incidence of Wernicke's encephalopathy (WE), which led the FDA to place a clinical hold on further drug development. However, upon further investigation it was determined that there was no clear evidence that fedratinib causes WE, and the clinical hold was lifted in 2017. This inclusive review provides insight into the pharmacology, safety and efficacy, and future direction of fedratinib use in myeloproliferative neoplasms.

Activator protein-2 (AP-2) is a transcription factor that regulates proliferation and differentiation in mammalian cells and has been implicated in the acquisition of the metastatic phenotype in several types of cancer. Herein, we examine the role of AP-2alpha in colon cancer progression. We provide evidence for the lack of AP-2alpha expression in the late stages of colon cancer cells. Re-expression of the AP-2alpha gene in the AP-2alpha-negative SW480 colon cancer cells suppressed their tumorigenicity following orthotopic injection into the cecal wall of nude mice. The inhibition of tumor growth could be attributed to the increased expression of E-cadherin and decreased expression and activity of matrix-metalloproteinase-9 (MMP-9) in the transfected cells, as well as a substantial loss of their in vitro invasive properties. Conversely, targeting constitutive expression of AP-2alpha in AP-2-positive KM12C colon cancer cells with small interfering RNA resulted in an increase in their invasive potential, downregulation of E-cadherin and increased expression of MMP-9. In SW480 cells, re-expression of AP-2alpha resulted in a fourfold increase in the activity of E-cadherin promoter, and a 5-14-fold decrease in the activity of MMP-9 promoter, indicating transcriptional regulation of these genes by AP-2alpha. Chromatin immunoprecipitation assay showed that re-expressed AP-2alpha directly binds to the promoter of E-cadherin, where it has been previously reported to act as a transcriptional activator. Furthermore, chromatin immunoprecipitation assay revealed AP-2alpha binding to the MMP-9 promoter, which ensued by decreased binding of transcription factor Sp-1 and changes in the recruitment of transcription factors to a distal AP-1 element, thus, contributing to the overall downregulation of MMP-9 promoter activity. Collectively, our data provide evidence that AP-2alpha acts as a tumor suppressor gene in colon cancer..

OBJECTIVES: To examine the association of exposure to sociodemographic, environmental, and lifestyle risk factors during adolescence with the development of multiple sclerosis (MS). METHODS: We conducted a case-control study between October 2017 and January 2018 at King Fahd General Hospital (KFH) in Madinah, Saudi Arabia. Data were collected by direct physician-subject interviews. We utilized a questionnaire modified from the environmental risk factors in multiple sclerosis questionnaire (EnvIMS-Q). Chi-square tests were used to examine associations of selected risk factors with the development of MS, a p-value of less than 0.05 was considered significant. RESULTS: A total of 80 cases and 160 controls were enrolled into the study. Smoking during adolescence significantly increased the risk of MS, with an adjusted odds ratio (AOR) of 4.165, and a 95% confidence interval (CI) of 1.449-11.974. Large body size, assessed using a figure rating scale, also increased the risk of MS (AOR=8.970, 95% CI=1.032-77.983), as well as a history of measles infection (AOR=3.758, 95% CI=1.455-9.706). Furthermore, exposure to sunlight during the weekend for more than 4 hours/day decreased the risk of MS (AOR=0.063, 95% CI=0.006-0.654), so did the consumption of fish for more than once per week (AOR=0.206, 95% CI=0.055-0.773). Conclusion: The risk of developing MS is significantly increased by exposure during adolescence to smoking, a history of measles infection, and large body size (obesity).

This work is aimed at evaluating the effect of repeated intracavernosal injection (ICI) self-injection on the peak systolic velocity (PSV) and the diameter of cavernosal arteries. Sixty erectile dysfunction (ED) patients who were positive responders for ICI therapy were studied. Pharmacopenile duplex ultrasonography (PPDU) was carried out before starting ICI and after 10 doses of home therapy in an open-label uncontrolled study. There was significant increase in the cavernosal artery diameter and their PSV before and after injection. Cavernosal arteries diameter before injection in both right and left sides was 0.64+/-0.13 and 0.63+/-0.12 mm at the start and became 0.81+/-0.22 and 0.79+/-0.22 mm respectively at the end with significant differences (P<0.001). Cavernosal arteries diameter after injection in both right and left sides was 1.10+/-0.18 and 1.09+/-0.19 mm at the start and became 1.34+/-0.39 and 1.27+/-0.33 mm respectively at the end with significant differences (P<0.001). PSV at the start was 33.77+/-13.26 and 32.33+/-8.09 cm/s on both right and left sides and became 44.4+/-1.19 and 46.1+/-5.86 cm/s respectively at the end with significant differences (P<0.001). It is concluded that repeated ICI improves arterial erectile response with associated increase in PSV and cavernosal artery diameters.

While therapy-related (t)-myelodysplastic syndromes (MDS) have worse outcomes than de novo MDS (d-MDS), some t-MDS patients have an indolent course. Most MDS prognostic models excluded t-MDS patients during development. The performances of the International Prognostic Scoring System (IPSS), revised IPSS (IPSS-R), MD Anderson Global Prognostic System (MPSS), WHO Prognostic Scoring System (WPSS) and t-MDS Prognostic System (TPSS) were compared among patients with t-MDS. Akaike information criteria (AIC) assessed the relative goodness of fit of the models. We identified 370 t-MDS patients (19%) among 1950 MDS patients. Prior therapy included chemotherapy alone (48%), chemoradiation (31%), and radiation alone in 21%. Median survival for t-MDS patients was significantly shorter than for d-MDS (19 vs 46 months, P<0.005). All models discriminated survival in t-MDS (P<0.005 for each model). Patients with t-MDS had a significantly higher hazard of death relative to d-MDS in every risk model, and had inferior survival compared to patients with d-MDS within all risk group categories. AIC Scores (lower is better) were 2316 (MPSS), 2343 (TPSS), 2343 (IPSS-R), 2361 (WPSS) and 2364 (IPSS). In conclusion, subsets of t-MDS patients with varying clinical outcomes can be identified using conventional risk stratification models. The MPSS, TPSS and IPSS-R provide the best predictive power.
