The Incidence of Abnormal Preoperative Testing Among Elective Surgery Patients in a Referral Hospital in Southern Saudi Arabia.

Background Preoperative investigations are important to assess the clinical condition of patients who undergo elective surgical procedures. However, there is still debate about the usefulness of performing preoperative investigations. We aimed to determine the prevalence of routine preoperative investigation abnormalities among elective general surgery patients. Methodology This retrospective hospital-record-based study was conducted at the King Abdullah Hospital in Bisha Province, southern Saudi Arabia. General and clinical data of 968 patients who underwent elective surgical interventions from February 2022 to January 2023 were retrieved and analyzed. Result A total of 968 patients (578 females and 390 males) aged between 14 and 80 years were included in the study. Four hundred and eleven (42.5%) patients were in the age group of 40 years and above. The commonly detected comorbidities among the patients were diabetes (15%), hypertension (12%), respiratory diseases (7.5%), and cardiac diseases (2.5%). Abnormalities related to hemoglobin (31%), total leucocyte count (12.7%), and platelets (8.5%) were found in 968 patients. Around 15% of patients had increased creatinine levels. Hypokalemia was observed in 6.8% of patients. Increased liver enzymes were reported in limited proportions (10% to 14%) of patients. Slightly abnormal radiological findings were reported for chest X-ray (CXR) (2.8%), electrocardiogram (ECG) (2%), and Doppler echocardiography (Echo) (0.8%). A statistically significant association between the age of the patient and abnormal findings of ECG (p <.001), Echo (p = .001), and CXR (p <.001). Cardiac abnormalities were commonly associated with patients of ≥ 40 years. Abnormal cardiac findings (CXR, ECG, Echo) were significantly (p<.05) increased with the presence of diabetes, hypertension, and cardiovascular comorbidities. Conclusions Preoperative testing revealed limited proportions of abnormal findings among patients with elective surgical procedures. Routine ordering of many preoperative investigations without specifications may not predict postoperative complications of the patients. Therefore, undertaking preoperative testing should be guided by targeted history, physical examination, clinical risk factors, and type of surgical procedure intended to be performed.

Neonatal epididymo-orchitis with pyocele mimicking testicular torsion: A case report.

We report a case of epididymo-orchitis (EO) in a 12-day-old Saudi boy. The neonate, initially diagnosed with hydrocele post-delivery, presented with left scrotal swelling. Doppler ultrasound revealed normal testicles but an enlarged, echogenic left epididymis with pyocele. Despite initial therapy with amoxicillin and cefotaxime, a repeated ultrasound indicated compromised testicular vascularity, necessitating emergency surgical exploration. This revealed purulent discharge and inflammation, with Escherichia coli as a causative agent. Post-surgery, the patient showed significant improvement and was discharged in good condition after a ten-day of hospitalization. The study emphasizes the significance of including EO in the possible diagnoses for neonatal scrotal swelling.

Epidemiology, pathogenicity, risk factors, and management of Helicobacter pylori infection in Saudi Arabia.

Helicobacter pylori (H. pylori) is a gastric microbial pathogen that infects approximately half of the global population. This bacterium significantly contributes to various gastroduodenal diseases, including chronic active gastritis, peptic ulcerations, and malignant transformations. This review focuses on epidemiology, pathogenicity, virulence genes, risk factors, and management of H. pylori infection, specifically within the context of Saudi Arabia. The results presented here are grounded in studies conducted in Saudi Arabia, contrasting with mere bibliographic reviews of findings from other countries. H. pylori infection has been observed in Saudi Arabia, with substantial differences in the prevalence, ranging between 10-96% among various studied populations. Several risk factors for H. pylori infection have been identified, encompassing socioeconomic status, medical history, personal hygiene, and behavioral practices. Among the virulence genes harbored by H. pylori, cytotoxin-associated gene A (cagA) and vacuolating cytotoxin (vacA) are most common, with their presence correlating with the pathogenicity and clinical manifestations of the associated diseases. A range of invasive and non-invasive diagnostic assays have been utilized to identify H. pylori infection, with their employment being influenced by factors like availability, cost, patient age, gastric symptoms, and the specifics of clinical information sought. While detection methods like the H. pylori stool antigen test and the urea breath test offer more accuracy and speed, culturing remains indispensable for determining the antimicrobial susceptibility profile. The emergence of resistant strains across varying regional settings poses a significant challenge to treatment endeavors, necessitating an assessment of local antimicrobial resistance rates prior to formulating treatment strategies. The findings of this review highlight the importance of continuous implementation of screening, control, and prevention of H. pylori infection to combat the spreading infection and other related complications.

Detection of Helicobacter pylori in Gastric Biopsies Among Sudanese Patients with Confirmed Gastric Disorders Using Three Diagnostic Methods.

BACKGROUND: Helicobacter pylori (H. pylori) infection represents one of the most common chronic bacterial infections in developing countries. However, in Sudan, the infection is not well diagnosed with standard laboratory methods in many parts of the country. This study aimed to detect H. pylori in gastric biopsies of patients with gastric disorders, using three diagnostic methods. MATERIALS AND METHODS: A cross-sectional study was conducted among 100 patients in Gezira state, central Sudan. Giemsa stain for histopathological examination (HPE), rapid urease test (RUT), and polymerase chain reaction (PCR) techniques were performed to detect H. pylori from the gastric biopsy samples as per standard assays. RESULTS: Most of the patients were males (66%), from rural areas (72%) and in the age group 31 to 50 years. H. pylori were identified in 85% of the samples by at least one of the three tests. The highest positivity was detected by HPE (83%), followed by PCR (67%) and RUT (63%), while 59% were positive by the three diagnostic methods. PCR showed higher sensitivity (80.72% vs. 73.49%) and specificity (100% vs. 88.24%) than RUT. Positive predictive values were reported as 100% for PCR and 96.83% for RUT. Considering PCR as a gold standard method, HPE revealed higher sensitivity (100%) than RUT (88.06%). On the contrary, RUT showed higher specificity (87.88%) than PCR (51.52%). There were no significant associations between H. pylori infection patients' gender (p = 0.747). Loss of weight (p = 0.007) and nausea (p = 0.032) were significantly associated with H. pylori infection. CONCLUSIONS: There was a high prevalence of H. pylori infection in central Sudan. This highlights the need to analyze epidemiological status, virulence factors, and strain characteristics to control disease transmission. PCR is a reliable and valuable technique in detecting H. pylori infection from gastric biopsy samples.

Prevalence of Acinetobacter baumannii in Saudi Arabia: risk factors, antimicrobial resistance patterns and mechanisms of carbapenem resistance.

Acinetobacter baumannii is an important opportunistic pathogen due to its capabilities for developing mechanisms of resistance to a wide range of antimicrobial agents including carbapenems. This review described the risk factors, antimicrobial susceptibility and mechanisms of carbapenem resistance of A. baumannii from different geographical regions of Saudi Arabia. Several factors including complexity of intensive care unit (ICU) environments, increased numbers of patients with serious diseases, wide spread gastrointestinal colonization and extensive use of antimicrobial drugs led to a wide prevalence of A. baumannii infections in hospitals in Saudi Arabia. A. baumannii has been noted to be less susceptible to antimicrobials agents, including carbapenems, over time, resulting in the evolution of multidrug-resistant (MDR) strains. Dissemination of MDR A. baumannii is attributed to the extreme use of wide-spectrum antimicrobial drugs in hospitals, cross infection between inpatients, invasive ICU procedures, and hospitalized patients with diabetic and cancer those are under frequent invasive diagnostic and therapeutic interventions. Although an increasing prevalence of colistin and tigecycline resistance has been reported in many hospitals, combinations of these agents with carbapenems or other antibiotics remain the best therapeutic choice and reasonably safe to treat patients with MDR A. baumannii infections. The wide distribution of carbapenem resistant A. baumannii (CRAB) due to several mechanisms with diverse genetic determinants has been documented. Although OXA-23 ß-lactamase and OXA-51 ß-lactamase are the most common genes responsible for CRAB, other novel genes such as blaVIM, PER-1-like and GES-5 have been discovered in carbapenem resistant strains. The high rates of MDR A. baumannii in Saudi hospitals indicate that extensive investigation into the molecular basis of MDR and developing new therapies of CRAB is needed. Moreover, the development of a local antibiogram database coupled with a nationwide antimicrobial stewardship and infection prevention program might help to improve our knowledge of the resistance patterns of A. baumannii, and in developing a treatment protocol for decreasing the infection burden in Saudi Arabia.

Vaginal infections among pregnant women at Omdurman Maternity Hospital in Khartoum, Sudan.

INTRODUCTION: Microbial infections of the vagina in pregnant women are health problems that lead to serious medical complications and consequences. This study aimed to investigate and determine antimicrobial susceptibilities of the causative agents of vaginal infections in pregnant women. METHODOLOGY: A cross-sectional study of pregnant women (n = 200) was conducted between August and December 2008 at Omdurman Maternity Hospital, Khartoum, Sudan. Vaginal and cervical swabs were obtained from each subject and processed for isolation and identification of pathogenic microorganisms using standard methods of wet mount preparation, direct Gram smear, Nugent scoring system, direct immunofluorescence, and cultural techniques. Antimicrobial susceptibility testing of bacterial isolates was performed using standard procedures. Statistical analysis was done using SPSS program version 12.0.1. A p value < 0.05 was considered statistically significant. RESULTS: Of the 200 pregnant women enrolled, BV was detected in 49.8%, followed by Chlamydia trachomatis (31.3%) and Candida albicans (16.6%), with low frequencies of Neisseria gonorrhoeae (1.8%) and Trichomonas vaginalis (0.5%). Higher infection rates were recorded among subjects in the third trimester (71.6%) than in the second trimester of gestation (28.4%). No significant association (p = 0.7) between history of abortions and C. trachomatis infections was found. Gentamicin was the most active agent against Gram-positive and Gram-negative bacteria. Clarythromycin was the most active against Mycoplasma species. CONCLUSIONS: Pregnant women with vaginal complaints revealed various positive microbiology results. Such cases may require specific medication. Routine culture of vaginal and cervical samples should be performed on all pregnant women during prenatal visits.
