Xanthogranulomatous orchitis: Review of the published work and report of one case

Xanthogranulomatous orchitis is an extremely rare inflammatory non-neoplastic destructive lesion of the testis. We report a 44-year-old man who presented with right scrotal swelling and two discharging sinuses. Testicular tumor markers were normal. Scrotal ultrasound showed heterogeneous testicular areas and irregular margin of the tunica. Surgical exploration revealed infected, unhealthy testicular tissue with necrosis and tumor-like lesion. Orchidectomy was done and histopathology showed xanthogranulomatous orchitis.     

Brain abscess in Saudi Arabia

There are significant variations among countries in the incidence of brain abscess. We report here 26 cases of brain abscess treated at the Neurosurgery Department of King Faisal University and Dammam Central Hospital Saudi Arabia over a six year period (1982–1988). This is 2.3% of total admissions to the two neurosurgery departments serving a population of approximately 1.2 million in the same period.Young males were most often affected (M/F ratio 3.3:1; 31% were less than 15 years old, 46% aged between 15–39 years, and 23% older than 40 years). Streptococcus was found to be the most common microorganism (38.4%). Mixed infection was seen in 15.3%, and sterile abscesses were found in 11.5% of the patients after aerobic and anaerobic cultures of the pus. Chronic otitis media and paranasal sinusitis predisposed the patients to abscess formation in 57.6% of the cases. The temporo-parietal area was the commonest site. Epilepsy was a complication in 30.7% of our patients, and the mortality rate was 15.3%.     

Correlation of carotid artery stump pressure with a palpable carotid artery pulse.

The carotid artery stump pressure has been used as a criterion for selective placement of a shunt during carotid endarterectomy. The purpose of our study was to correlate the carotid stump pressure with the presence or absence of a palpable pulse in the carotid stump. One hundred twenty-two consecutive patients undergoing carotid endarterectomy under general anesthesia were checked for a palpable pulse in the internal carotid stump with subsequent measurements of the stump pressure. Of these patients, 88 had a palpable pulse and a pressure greater than or equal to 44 mmHg. The remaining 34 had a absent pulse and a stump pressure of 40 mmHg or less. Shunts were not used in those patients with a palpable pulse and no history of previous stroke or contralateral carotid occlusion. There were no serious neurological complications. We conclude that the presence of a palpable pulse in the carotid stump is a sufficient criterion for performing carotid endarterectomy without a shunt in those patients with no previous history of stroke or contralateral carotid occlusion.     

Renal cell carcinoma with inferior vena cava tumor thrombi

Renal cell carcinoma is a unique neoplasm because of its common propensity to propagate into the renal vein and inferior vena cava (IVC) as tumor thrombus. Historically, the surgical difficulties encountered in removal of these cancers limited the ability of a single institution to obtain experience with large numbers of instances. Between January 1956 and July 1987, 68 patients with renal cell carcinoma extending into the IVC or right atrium underwent radical nephrectomy with vena cava thrombus extraction at the Cleveland Clinic. Twenty-five patients had partial resection of the IVC with reconstruction. Fifteen patients had partial resection and reconstruction of the IVC; however, because of narrowing of the infrarenal IVC, persisting bland thrombus in the proximal IVC or iliac veins or concern regarding postoperative pulmonary emboli, the infrarenal IVC was either ligated or clipped. Seven patients underwent cavectomy with division of the IVC. A right atriotomy was performed upon 14 patients and cardiopulmonary bypass was used in 20 patients, with 17 also having deep hypothermic circulatory arrest. The tumor thrombus was removed intact in 64 per cent of the patients and in multiple small fragments ("piecemeal") in 36 per cent of the patients. The mortality rate was 7 per cent. Survival was examined relative to extent of vena caval thrombus. Patients with extension into the atrium had a significantly worse prognosis than those with other levels of vena caval involvement. Other factors, such as lymph node status, perinephric fat involvement, resection of IVC and intact or "piecemeal" extraction, did not influence the survival rate. Patients with pre-existing metastases preoperatively had an extremely poor survival rate. The techniques now available for surgical resection of all levels of tumor thrombus of the IVC make resection feasible in most patients. In our opinion, the addition of deep hypothermic circulatory arrest has been a significant advance.

The role of electronic medical records in improving health care quality: A quasi-experimental study

The Teleprimary Care—Oral Health Clinical Information System (TPC-OHCIS) is an updated electronic medical record (EMR) that has been applied in Malaysian primary healthcare. Recognizing the level of patient satisfaction following EMR implementation is crucial for assessing the performance of health care services. Hence, the main objective of this study was to compare the level of patient satisfaction between EMR-based clinics and paper-based clinics.The study was a quasi-experimental design that used a control group and was conducted among patients in 14 public primary healthcare facilities in the Seremban district of Malaysia from May 10, to June 30, 2021. Patient satisfaction was assessed using the validated Short-Form Patient Satisfaction Questionnaire, which consisted of 7 subscales. All data were analyzed using the IBM Statistical Package for Social Sciences version 21.A total of 321 patients consented to participate in this study, and 48.9% of them were from EMR clinics. The mean score for the communication subscale was the highest at 4.08 and 3.96 at EMR-adopted clinics and paper-based record clinics. There were significant differences in general satisfaction and communication subscales, with higher patient satisfaction found in clinics using EMR.With the utilization of EMR, patient satisfaction and communication in delivering healthcare services have improved.     

Investigation of the Renal Protective Effect of Combined Dietary Polyphenols in Streptozotocin-Induced Diabetic Aged Rats

Natural polyphenols are widely reported to have a large range of pharmacological properties, especially antioxidant activities and free radical scavenging capacities. In this study, we investigate the effects of naringin, chlorogenic acid, and quercetin mixtures (NCQ) on renal fibrosis in streptozotocin (STZ)-induced diabetic aged rats and its underlying mechanisms for ten consecutive weeks. The oxidative defense system in the kidneys of treated rats was found to be improved. Several biomarkers were investigated including the blood urea nitrogen, creatinine, and uric acid. Moreover, antioxidant parameters were evaluated and we found that superoxide dismutase, catalase, glutathione peroxidase, Na⁺-K⁺-ATPase activities, the nitric oxide production, the protein carbonyl, the advanced oxidation protein products, lipid peroxidation, and reduced glutathione levels were all significantly balanced and close to control values. In addition, NCQ restored renal injuries and fibrosis as assessed by histological method and molecular biology investigation of the matrix metalloproteinase, the transforming growth factor-beta TGF-β, the tumor necrosis factor TNFα, and p53 expression. Our study proposes the NCQ combination as potential plant-derived bioactive compounds to prevent diabetic nephropathy.     

Oxidative stress in patients with asthma and its relation to uncontrolled asthma

This study aims to evaluate markers of oxidative stress in Tunisian asthmatic patients and investigate whether their markers are correlated with uncontrolled asthma.This prospective cohort study was conducted on 48 healthy subjects and 60 patients with asthma (34 patients with controlled asthma and 26 patients with uncontrolled asthma). The levels of malondialdehyde (MDA), advanced oxidation protein products (AOPP), and glutathione (GSH), as well as the activities of glutathione peroxidase (GPx) and superoxide dismutase (SOD), were estimated in plasma by spectrophotometry.Asthmatic patients have significantly higher plasmatic levels of MDA and AOPP than healthy controls (p < 0.001). Lower GSH level and GPx activity were found in patients with asthma compared to controls (p < 0.001). In contrast, higher SOD activity was noted in asthmatic patients (p < 0.001).The comparison among the patients with controlled asthma and uncontrolled asthma revealed increased MDA and AOPP levels and SOD activity (p < 0.001) as well as a decreased GSH level and GPx activity (p = 0.004, p = 0.019) in patients with uncontrolled asthma. Spirometry level was significantly correlated with SOD activity (r = 0.447; p = 0.010), whereas no significant correlations were found with the other parameters (MDA, AOPP, GSH, and GPx).Asthmatic patients, especially those with uncontrolled asthma, suffer a high degree of reactive oxygen species (ROS) formation causing considerable oxidative stress. Increased MDA level and SOD activity and reduced GPx activity were predictors of poorly controlled asthma.     

Duloxetine, a serotonin and noradrenaline reuptake inhibitor (SNRI) for the treatment of stress urinary incontinence: a systematic review

OBJECTIVE: Surgery and pelvic floor muscle training are established methods for treating stress urinary incontinence (SUI). A new serotonin and noradrenaline reuptake inhibitor, duloxetine, has been studied in multiple phase 3 trials as a form of medical management of this condition. This systematic review determined the effectiveness and acceptability of duloxetine in managing SUI. METHODS: We reviewed all randomised controlled trials comparing duloxetine with placebo or no treatment. The search included the Cochrane Incontinence Group specialised register, CENTRAL, MEDLINE, PREMEDLINE, dissertation abstracts, and the reference lists of relevant articles. The primary outcome was the number of participants whose symptoms were "cured" while on treatment. Secondary outcomes included subjective improvement, incontinent episodes, quality of life, adverse events, and discontinuation rates. RESULTS: Nine trials were included, totalling 3063 women with predominantly SUI, all randomised to receive duloxetine or placebo. Treatment duration was 3-36 wk. Subjective cure favoured duloxetine (from three trials, 10.8% vs. 7.7%; RR=1.42; 95%CI, 1.02-1.98, p=0.04). The limited data available to assess objective cure rates were consistent with this. Individual studies showed a significant reduction in the Incontinence Episode Frequency (IEF) by approximately 50% during treatment. Duloxetine groups had significantly better quality-of-life scores (weighted mean difference for Incontinence Quality of Life Index for participants on 80 mg daily: 4.5; 95%CI, 2.83-6.18; p<0.00001) and rates of symptom improvement. Adverse effects were common (71% vs. 59%) but are reported as not serious and were equivalent to about one in eight participants reporting adverse effects (most commonly nausea) directly related to duloxetine treatment. About one in eight stopped treatment as a consequence of taking duloxetine (17% vs. 4%). CONCLUSIONS: Duloxetine can significantly improve the quality of life of patients with SUI, but it is unclear whether or not benefits are sustainable. Side-effects such as nausea are common.
