The Correlation of Paternal Age on Semen Parameters in Assisted Reproduction: A Retrospective Study in Qassim, Saudi Arabia.

INTRODUCTION: In the past, fertility concerns have predominantly revolved around the effect of a woman's age on the quality of her eggs and the success of her pregnancy. While men generally retain their ability to father children throughout their lives, there is evidence suggesting a decline in natural conception rates as paternal age increases. A growing body of research indicates a potential link between advanced paternal age (APA) and various adverse outcomes, including changes in sperm genetics, reduced conception rates, higher rates of miscarriage, lower live birth rates, and even long-term health consequences in offspring. However, it remains unclear whether there is an association between APA and the effectiveness of assisted reproductive technology (ART). This study aims to shed light on the relationship between APA and semen parameters. METHODOLOGY: This is a retrospective, descriptive study analyzing data from electronic medical records of men undergoing ART at a fertility clinic in Saudia Arabia (2017-2022). Men aged 21-60 with at least one semen analysis and no missing data/hormonal treatment were included. Data on age and semen parameters (count, motility, and morphology) were extracted and analyzed using Jeffreys's Amazing Statistics Program (JASP; University of Amsterdam, Amsterdam, Netherlands) (descriptive statistics, Spearman's rank correlation). RESULTS: Analysis of 1506 men undergoing ART revealed a mean age of 37 years (SD=6.94) and a mean sperm count of 55.0 million/mL (SD=46.05). The correlation between age and sperm count indicates a minimal association (r=0.075, p<0.01); moderate positive correlations were observed between sperm count and motility (r=0.406); count and morphology (r=0.543); and motility and morphology (r=0.458). CONCLUSION: Age may not be a major factor in overall sperm parameters for this population, but a strong positive correlation was observed between sperm count, motility, and normal morphology. These findings suggest that these semen parameters are interconnected, with higher sperm counts potentially indicating better overall sperm quality.

Late port-site metastasis of unexpected gallbladder carcinoma after laparoscopic cholecystectomy: A case report.

INTRODUCTION: Incidental gallbladder carcinoma refers to a discovery of gallbladder cancer during or after cholecystectomy. Late port-site metastasis (PSM) following Laparoscopic cholecystectomy (LC) is rare with an incidence rate of 10.3%. PATIENT CONCERNS: We report a case of a 58-year-old man who presented with a painful abdominal wall mass for 6 weeks. He had a history of LC for symptomatic cholelithiasis, 8 years prior. DIAGNOSIS: Histopathological examination revealed a positive result for metastatic adenocarcinoma from the abdominal wall mass. Moreover, Positron emission tomography (PET) showed a small focus of intense fluorodeoxyglucose (FDG) uptake in the gallbladder bed, which was highly suspicious for malignancy. INTERVENTION: Decision was to proceed with surgery owing to uptake in the gallbladder bed with single-site metastasis to the previous port site. In addition, in the board meeting, an agreement was reached for performing distal pancreatectomy with splenectomy owing to uncertainty of malignancy based on what was discovered during the full metastatic workup. Diagnostic laparoscopy followed by midline laparotomy performed. Radical completion cholecystectomy with lymphadenectomy was done. Followed by complete resection of the anterior abdominal wall. Distal pancreatectomy and splenectomy were then performed. OUTCOME: Pathological diagnosis showed metastatic/invasive, moderately differentiated adenocarcinoma with positive margins on the posterior surface of excised port-site mass. The positive margins necessitated further chemoradiotherapy, followed by adjuvant chemotherapy until lung metastasis was identified. After this, the patient was scheduled for palliative chemotherapy. CONCLUSION: Presence of PSM is often associated with peritoneal metastasis. For this reason, it is advised to evaluate the patient for possible metastasis.

Management and Outcomes of Traumatic Liver Injury: A Retrospective Analysis from a Tertiary Care Center Experience.

BACKGROUND: although liver injuries are one of the most critical complications of abdominal trauma, choosing when to operate on these injuries is challenging for surgeons worldwide. METHODS: We conducted a retrospective analysis of liver injury cases at our institution from 2016 to 2022 to describe the operative and nonoperative management (NOM) outcomes in patients with traumatic liver injuries. Baseline patient characteristics, liver injury details, treatments, and outcomes were analyzed. RESULTS: Data from 45 patients (male, 77.8%) were analyzed. The mean age was 29.3 years. Blunt trauma was the most common injury mechanism (86.7%), whereas penetrating injuries were 8.9% of cases. Conservative management was associated with 18.9% of complications. The overall complication rate was 26.7%; delirium and sepsis were the most common (13.3%), followed by acute renal failure (4.4%), pneumonia, biliary leaks, and meningitis/seizures. CONCLUSIONS: Notwithstanding its limitations, this retrospective analysis demonstrated that NOM can serve as a safe and effective strategy for hemodynamically stable patients with liver trauma, irrespective of the patient's injury grade. Nevertheless, careful patient selection and monitoring are crucial. Further investigations are necessary to thoroughly evaluate the management of traumatic liver injuries, particularly in the context of multiorgan injuries.

Multifocal Primary Pancreatic Adenocarcinoma With No Precursor Lesion: A Report of Two Cases.

The aim of this clinical case report is to highlight the unusual presentation of pancreatic malignancy in which multiple foci of primary adenocarcinoma involving the body and tail of the pancreas are associated with another primary pancreatic mass of adenocarcinoma in the pancreatic head with no precursor lesions in two cases. A retrospective medical chart review was performed at a tertiary hospital in Riyadh, Saudi Arabia, to identify cases with confirmed multifocal pancreatic adenocarcinoma. Data collected include clinical evaluations and laboratory and imaging results. Informed consent was waived. There was no evidence of multifocal cancer on imaging. The unexpected intraoperative findings and pathology report necessitated a total pancreatectomy for both cases. A negative imaging does not rule out a multifocal pancreatic adenocarcinoma. Such awareness may help in the early detection of pancreatic cancer. Moreover, the presence of more than one primary cancer in one organ is a distinctive phenomena that needs further study.

Early versus delayed cholecystectomy in biliary pancreatitis: Experience from a Local Acute Care Surgery Unit in Saudi Arabia.

Biliary pancreatitis is a common complication of gallstones. Although most patients experience mild disease, around 20% may develop severe pancreatitis with an increased risk of serious complications during recurrent attacks. The objective of our study is to compare the surgical outcomes and length of stay for early versus delayed cholecystectomy, performed within the same admission, for mild pancreatitis in a Saudi tertiary center with an established Acute Care Surgey Unit. This retrospective cohort study included all patients who underwent cholecystectomy during the index admission for biliary pancreatitis between January 2017 and January 2020. Surgical outcomes and hospital length of stay were collected and analyzed to assess overall outcomes for early and delayed cholecystectomy groups. The early group was defined as surgery performed within 72 hours of presentation. Eighty-six patients were included and allocated to the early and delayed cholecystectomy groups. The median length of hospital stay was significantly shorter in the early cholecystectomy group (4 days, IQR 3-5) compared to the delayed group (7 days, IQR 6-9) (P < .001). There was no significant difference in operative time and postoperative complications. Early cholecystectomy for mild biliary pancreatitis appears safe and feasible and may result in a shorter hospital stay.

Sunflower and Watermelon Seeds and Their Hybrids with Pineapple Leaf Fibers as New Novel Thermal Insulation and Sound-Absorbing Materials.

Pineapple leaf fiber (PALF), striped sunflower seed fiber (SFSF), and watermelon seed (WMS) are considered natural waste polymer materials, which are biodegradable and sustainable. This study presents new novel thermal insulation and sound absorption materials using such waste as raw materials. PALF, SFSF, and WMS were used as loose, bound, and hybrid samples with different compositions to develop promising thermal insulation and sound-absorbing materials. Eleven sample boards were prepared: three were loose, three were bound, and five were hybrid between PALF with either SFSF or WMS. Wood adhesive was used as a binder for both the bound and hybrid sample boards. Laboratory scale sample boards of size 30 cm × 30 cm with variable thicknesses were prepared. The results show that the average thermal conductivity coefficient for the loose samples at the temperature range 20-80 °C is 0.04694 W/(m.K), 0.05611 W/(m.K), and 0.05976 W/m.K for PALF, SFSF, and WMS, respectively. Those for bound sample boards are 0.06344 W/(m.K), 0.07113 W/(m.K), and 0.08344 W/m.K for PALF, SFSF, and WMS, respectively. The hybrid ones between PALF and SFSF have 0.05921 W/m.K and 0.06845 W/(m.K) for two different compositions. The other hybrid between PALF and WMS has 0.06577 W/(m.K) and 0.07007 for two different compassions. The sound absorption coefficient for most of the bound and hybrid boards is above 0.5 and reaches higher values at some different frequencies. The thermogravimetric analysis for both SFSF and WMS shows that they are thermally stable up to 261 °C and 270 °C, respectively. The three-point bending moment test was also performed to test the mechanical properties of the bound and hybrid sample boards. It should be mentioned that using such waste materials as new sources of thermal insulation and sound absorption materials in buildings and other applications would lead the world to utilize the waste until zero agrowaste is reached, which will lower the environmental impact.

Comparison of Enamel Surface Integrity after De-Bracketing as Affected by Seven Different Orthodontic Residual Cement Removal Systems.

This study used seven different adhesive removal systems to evaluate and compare enamel surface integrity, heat generation, and time consumed during residual cement removal after de-bracketing. The sample size was 140 human premolars. Teeth were cleaned, mounted, and prepared for orthodontic bracket bonding. Brackets were then debonded using bracket-removing pliers. Teeth were randomly assigned to seven groups based on the residual cement removal system: Group 1: Stainbuster bur, Group 2: Renew diamond bur #129, Group 3: Renew carbide bur, Group 4: OneGloss Complete system, Group 5: Sof-Lex system, Group 6: Enhance Finishing and PoGo Polishing complete kit, and Group 7: Renew friction grip points. The enamel surface was evaluated for roughness before bracketing and after residual cement removal using surface profilometry. The time taken for cement removal was recorded using a digital timer, and heat generation was measured using a laser thermometer before and after cement removal. One-way ANOVA compared the pre- and post-values for enamel surface roughness, temperature, and time consumed. When comparing the difference between the post- and pre-finishing roughness using one-way ANOVA, the Renew diamond bur produced the roughest enamel surface post-removal with a mean of 4.716 µm, while the Sof-Lex recorded the lowest at 0.760 µm. The highest mean temperature was recorded with the Stainbuster bur at 5.545 °C, and the lowest temperature was recorded with the Enhance bur at 2.260 °C. The time for cement removal was the shortest with the Enhance bur at 12.2 s, whereas the time was the longest with the Renew diamond bur at 30.4 s. In conclusion, all the residual cement removal systems used in this clinically simulated study were not able to restore the original enamel surface smoothness. However, the 3M Sof-Lex produced the lowest enamel roughness but with more time consumption and heat generation. When selecting the best residual cement removal system to be used, clinicians should weigh the merits and demerits of each system based on the clinical judgement of the operator.

Initial Outcomes of Freehand Transperineal Biopsies Regarding Diagnostic Value and Safety: An Early Experience at King Fahad Specialist Hospital, Buraydah, Saudi Arabia.

BACKGROUND: Prostate cancer is a common type of cancer in Saudi Arabia with a high incidence rate. Trans-rectal ultrasound guided prostatic biopsy (TRUSBx) has been the standard diagnostic study for prostate cancer since a landmark study in 1989 which showed that it is better than digitally directed biopsy sampling of the prostate. As an alternative to TRUSBx, transperineal biopsies (TPBx) have gained popularity as they give a higher accuracy rate and avoid many complications. A new study has been conducted in Riyadh, Saudi Arabia to compare TRUSBx and TPBx showed that TPBx has a significantly higher detection rate of prostate cancer cases compared to TRUSBx (45.1% vs. 29.1%, p=0.003). The aim of this study is to determine the diagnostic value and safety of freehand transperineal prostate biopsy in patients with an elevated prostatic specific antigen (PSA) and/or abnormal digital rectal exam in King Fahad Specialist Hospital KFSH in Buraydah, Qassim region, Saudi Arabia. METHODS: This is an observational retrospective study of all patients (n=39) who underwent transperineal biopsies at KFSH to assess the diagnostic value and safety of the procedure. RESULTS: The mean age of the patients was 70.3 (SD 10.1) years. The most commonly found diagnosis was adenocarcinoma (61.5%), and incidence of complications was detected in (5.1%) of the patients. CONCLUSION: We concluded that the freehand technique TPBx has a high accuracy rate in detecting prostatic cancer. However, the learning curve could be a limiting factor in implementing it. Increasing the number of biopsies could positively affect diagnostic accuracy, especially with our low complication rate in this procedure. A low number of biopsies in the older age group can give an accurate result with a low risk of complications. Although template-guided TPBx and robot-guided TPBx are better options, the freehand technique represents a cost-effective and time-saving alternative. However, more studies are needed to compare the outcome of such a technique.

An incidental intra-operative finding of sclerosing encapsulating peritonitis, "abdominal cocoon" in an emergency presentation of small bowel obstruction, a case report.

INTRODUCTION AND IMPORTANCE: Sclerosing encapsulating peritonitis (SEP) is a disease characterized by a chronic inflammatory process in which the small intestines are encased by a dense fibrocollagenous membrane. In this article, we report a 57 year old male who presented with bowel obstruction secondary to sclerosing encapsulating peritonitis with an initial imaging suggesting internal hernia. CASE PRESENTATION: A 57-year-old male, who presented to the emergency department at our center with a chronic persistent nausea and vomiting, associated with anorexia, constipation and weight loss, CT scan showed a transition zone seen at the duodeno-jejunal (DJ) junction and findings suggesting internal hernia, he was treated conservatively initially followed by a diagnostic laparoscopy that was converted to open with intraoperative findings of intra-abdominal cocoon rather than an internal hernia, managed with adhesolysis and discharged home in stable good condition. CLINICAL DISCUSSION: There are multiple factors that could attribute to PSEP including cytokines, fibroblasts, and angiogenic factors, such patients might be asymptomatic or presenting with GI obstruction symptoms. The diagnosis of PSEP varying from abdominal x rays to contrast enhanced CT scan. CONCLUSION: The management of PSEP depends on the presentation and should be individualized, weather conservative medical or surgical approach can be used.

Glycemic Control for Type 2 Diabetes Mellitus Patients: A Systematic Review.

Diabetes mellitus is a chronic metabolic disorder resulting in hyperglycemia and microvascular and macrovascular complications in individuals globally. Type 2 diabetes mellitus (T2DM) is highly prevalent and accounts for 90% of patients. Maintaining blood glucose concentration is essential to avoid severe complications. Glycemic control is the optimal serum glucose concentration in diabetic patients. It is necessary to identify factors affecting the glycemic control of patients to prevent control and complications. We conducted this systematic review to assess the factors affecting glycemic control among type 2 diabetes mellitus patients. Published literature between the years 2020 to 2022 was retrieved from PubMed, Science Direct, and Google Scholar using different combinations of keywords: T2DM, Glycemic control, Poor, Good, Adequate, Inadequate, Factors, Association, and Determinants. All original articles written in the English language with full-text available and the value of glycemic control defined were included. A total of 1866 studies were retrieved. After the title, abstract, screening, and full-text screening, 12 studies were eligible. The prevalence of poor glycemic control was high, and it ranged between 45.2% and 93% among the studies. The factors associated with glycemic control were stratified into four categories: personal or body-related, clinical, medication-related, and behavioral factors. There was a high prevalence of poor glycemic control in all included studies. The glycemic control was associated with various factors; some were related to the patient or medical conditions while others were related to the behavior of the patients or the medication administrated.

Uremic Leontiasis Ossea in a Pediatric Patient.

Uremic leontiasis ossea (ULO) is a rare disease characterized by extensive thickening of the cranium, resulting in a characteristic, lion-like facial appearance. It is considered the most severe osseous complication of renal dystrophy. Although rare, ULO can occur even in young patients, which can be catastrophic, as it can not only lead to life-threatening conditions but also multiple complications that cause severe determent to the quality of life.

Multiple primary gastrointestinal tumors of gastric, pancreatic and rectal origin; a case report.

INTRODUCTION: The occurrence of multiple primary synchronous or metachronous malignancies is a described phenomenon. Such cases may have genetic predisposition or could be related to environmental risk factors but may also be sporadic. We are reporting a unique combination of triple primary synchronous malignancies in the same patient. CASE PRESENTATION: A 71 year old man presented with constipation and per rectal bleeding with a palpable mass 5-6 cm from the anal verge on physical examination. Colonoscopy with biopsy confirmed adenocarcinoma of rectal origin. After multi-disciplinary tumor board meeting, the patient received neoadjuvant chemoradiation therapy followed by single-stage surgery. Re-staging work up showed the presence of pancreatic lesion. Incidental finding of a gastric nodule upon surgical exploration which was confirmed to be a gastrointestinal stromal tumor. The patient had an uneventful postoperative course. DISCUSSION: Multiple primary malignancies of the gastrointestinal system has previously been reported in the literature; whether in the form of double, triple, quadruple or even quintuple primaries. Furthermore, gastrointestinal malignancies have been reported to be combined with extra-intestinal malignancies. However, this unique combination of pancreatic adenocarcinoma, rectal adenocarcinoma and gastric gastrointestinal stromal tumor has not been previously reported in the literature. Single-stage multiple resections was successful. CONCLUSION: We are reporting a unique case of three primary malignancies involving the rectum, pancreas and stomach. For such patients, there is no clear guidelines regarding management or surveillance, but rather should be individualized.

Fabrication of Custom Post-And-Core Using a Directly Fabricated Silicone Pattern and Digital Workflow.

This report introduces an alternative clinical and laboratory technique for the direct fabrication of a custom post-and-core pattern using poly (vinyl siloxane) (PVS) occlusal registration material, followed by a digital workflow. This technique decreases chairside time, eliminates the risk of locking the pattern into the postspace and improves accuracy of the custom post-and-core.

Assessment of hypertension and its associated risk factors among medical students in Qassim University.

Hypertension is a major risk factor for heart disease, stroke, kidney failure, and premature death. In Saudi Arabia, studies looking at the prevalence of hypertension in young adults are scarce. We aim to provide current data on the prevalence and associated risk factors of hypertension in young adults to allow us to assess the magnitude of the problem in this age group and suggest the appropriate recommendations to physicians and policymakers. The objective of the study is to assess the prevalence of hypertension and its associated risk factors in medical students attending the College of Medicine in Qassim University, Qassim, Saudi Arabia. It is a cross-sectional study that was conducted during the year 2017 on medical students attending the College of Medicine at Qassim University. A total of 130 students were selected using multistage stratified random sampling. We collected data on sociodemographic information and risk factors using a self-administered questionnaire derived from the WHO STEPS instrument, and we measured the blood pressure and body mass index (BMI) of the participants. Data were analyzed using Statistical Package for Social Sciences version 23.0. The prevalence of hypertension in the study sample was found to be 14.6%, 6.9% of which had isolated diastolic hypertension while 4.6% had isolated systolic hypertension, and the remaining 3.1% had systolic-diastolic hypertension. The prevalence of prehypertension was found to be 29.2%. Only 21.1% of the participants found to be hypertensive were diagnosed and on antihypertensive therapy. We found a significant association between gender, BMI, and history of diabetes and hypertension. Our study confirms the notion that there are high rates of prehypertension and hypertension among young adults, the majority of which are undiagnosed cases. This calls for the need of a comprehensive national screening program and campaigns that increase awareness about hypertension and its associated risk factors.

Evolving Management of Zenker's Diverticulum in the Endoscopic Era: A North American Experience.

BACKGROUND: Open surgical cricopharyngeal myotomy(CM) is considered standard of care for Zenker's diverticulum(ZD). Trans-oral CM has been described using a rigid stapling device for two decades; however, this remains problematic for severely kyphotic patients. This problem can be overcome with flexible endoscopy utilizing an electrosurgical needle knife. We sought to compare clinical outcomes between these techniques to stratify patient selection. METHODS: Patients undergoing ZD treatment from 1992 to 2015 were reviewed. Demographics, diverticulum size, post-operative complications, and length of stay (LOS) were compared between open cricopharyngeal myotomy (OpenCM), rigid trans-oral stapling myotomy (RigidCM), and flexible endoscopic myotomy (FlexCM). Dysphagia scores (DS, 0:best-4:worst) and pneumonia incidence were assessed pre-operatively and post-operatively. RESULTS: 62 patients underwent OpenCM (39/62(63 %)) or endoscopic CM (23/62(37 %) (8 RigidCM/15 FlexCM)). CM significantly reduced dysphagia for all approaches [OpenCM:2(2-3)-0(0-0); RigidCM:2(2-2)-0(0-0); FlexCM:3(3-3)-0(0-0)]. FlexCM patients had significantly worse pre-operative DS. Endoscopic CM was attempted and completed in 23/35(66 %) patients. Reasons for OpenCM conversion included inability to position the diverticular retractor due to patient body habitus (RigidCM), and the inability to position the overtube due to small ZD (FlexCM). Major post-operative complications were rare and similar in all groups. Medium-to-long-term post-myotomy pneumonia was comparable between groups. LOS (days) was reduced for FlexCM (1(1-2)) versus RigidCM (3(2-6)) and OpenCM (4(3-7)). CONCLUSIONS: CM is highly effective for treating ZD. Open and endoscopic approaches offer comparable outcomes and dysphagia resolution. FlexCM is efficacious for large ZD and can be performed in most patients irrespective of body habitus. FlexCM represents an excellent approach for large ZD, while OpenCM should be reserved for small ZD for which an overtube cannot be positioned.

Survival and recurrence patterns after neoadjuvant docetaxel, cisplatin, and 5-fluorouracil (DCF) for locally advanced esophagogastric adenocarcinoma.

INTRODUCTION: We have previously identified Docetaxel, Cisplatin, and 5FU (DCF) as a safe, tolerable, and effective regimen in the neoadjuvant setting for locally advanced adenocarcinoma (ADC) of the esophagus and esophagogastric junction (EGJ). We hypothesized that DCF combined with enhanced surgical control would result in a low rate of local or regional recurrence, and thus reviewed our outcomes with this treatment regimen. METHODS: A prospectively entered database of all esophageal and EGJ ADC patients resected at a high-volume referral center over 6 years (9/07-9/13) was reviewed for cases treated with curative intent neoadjuvant DCF followed by en bloc resection with extended lymphadenectomy (D2/D3). Recurrences was defined as locoregional (biopsy on endoscopy/regional lymph nodes (LNs)) and distant. Standard statistical techniques were used. RESULTS: Of 279 patients with ADC, 86 (85% male, mean age 63 years (interquartile range 56-70)) underwent preoperative DCF and curative intent resection for locally advanced ADC (cT3 93%; cN+ 69%) of the EGJ (54%) or distal esophagus (46%). After median follow-up of 40 months, the overall 5-year survival was 54% and 43 (52%) had recurred at a median time of 14 months. Sites of recurrence included locoregional only in 2 of 45 (4%), distant only in 40 of 45 (89%), and locoregional and distant in 3 of 45 (7%). DISCUSSION: The present study demonstrates favourable oncologic outcomes with low local/regional recurrence and an excellent overall 5-year survival after neoadjuvant DCF for esophageal and EGJ ADCs. Because the majority of recurrences were distant, our data support the notion that efforts to improve outcomes in these patients should concentrate on enhancing systemic, rather than local, therapy.

Transoral endoscopic resection of esophageal liposarcoma.

A 63-year-old man presented with a 1-month history of dysphagia. Endoscopy showed the patient had a mass in the cervical esophagus. Multiple biopsy specimens were taken, which were inconclusive for a diagnosis. A positron-emission tomography scan showed a hypermetabolic lesion. A transoral endoscopic approach was used to resect the tumor. Final histologic examination revealed a completely resected low-grade liposarcoma.
