Self-introduction of a two-meter nylon string into the urinary bladder: A case report

A foreign body of the urinary bladder can be caused by several factors. Several patients deliberately insert foreign bodies via the urethra due to psychiatric issues to achieve sexual pleasure. Self-inserted urinary bladder foreign bodies remain a significant challenge in the urology field regarding diagnosis and management as patients may be late in seeking medical assistance due to guilt and embarrassment. We aimed to report a 37-year-old man who inserted a two-meter nylon string into his urethra for sexual gratification.     

The effect of nettle (Urtica dioica) supplementation on the glycemic control of patients with type 2 diabetes mellitus: A systematic review and meta‐analysis

Type 2 diabetes mellitus (T2DM) is a major health problem, worldwide, that is associated with increased morbidity and mortality. Several randomized controlled clinical trials (RCTs) have investigated the effect of nettle (Urtica dioica) supplementation on markers of glycemic status in patients with T2DM, with conflicting results. Therefore, the present study assessed the effect of nettle on some glycemic parameters in patients with T2DM. A comprehensive search was conducted in PubMed, Scopus, Cochrane Library, and Web of Science, from database inception up to June 2019, to identify RCTs investigating the effect of nettle supplementation on glycemic markers, including fasting blood sugar (FBS) concentrations, insulin levels, homeostasis model assessment‐estimated insulin resistance index, and glycosylated hemoglobin percentage in adults with T2DM. The Cochrane Collaboration tool was used to assess the methodological quality of the included studies. Results of this meta‐analysis were reported based on the random effects model. Eight RCTs, comprising 401 participants, were included in the present systematic review and meta‐analysis. Based on the Cochrane Collaboration risk of bias tool, five studies were considered as good quality, one was fair, and two studies were poor, respectively. The results of the meta‐analysis revealed a significant reduction in FBS concentrations (weighted mean difference [WMD]: ?18.01 mg/dl, 95% confidence interval [CI]: ?30.04 to ?5.97, p < .001, I² = 94.6%) following nettle supplementation. However, no significant reduction was observed in insulin levels (WMD: 0.83 Hedges' g, 95% CI: ?0.26 to 1.92, p = .13, I² = 89.4%), homeostasis model assessment‐estimated insulin resistance index (WMD: ?0.22, 95% CI: ?0.83 to 0.40, p = .49, I² = 69.2%), or glycosylated hemoglobin percentage (WMD: ?0.77%, 95% CI: ?1.77 to 0.22, p = .12, I² = 83.0%). The findings of the present study suggest that nettle supplementation may be effective in controlling FBS for T2DM patients. However, further studies are needed to confirm the veracity of these results.     

Hidden risks in toys: A systematic review of pediatric toy contact dermatitis

Toys are a reflection of the compounds used frequently in manufacturing. Allergic contact dermatitis to potties, metal toys, and children's jewelry is well known, however, there is a broad range of skin risks in toys. With the objective to identify and publicize the associated risk of contact dermatitis in children's toys, we have searched the PubMed database from creation to September 9, 2019. Studies were eligible if they reported a new case of contact dermatitis secondary to interaction with a toy in patients from birth to 18 years of age. A toy was defined as something children interact with for entertainment during leisure time. In this review of the PubMed database we filtered by age and language which may have prevented us from detecting cases in adults that could be extrapolated to children. In addition, several articles were excluded based on title alone. A total of 1312 articles were identified and reviewed manually for inclusion criteria. Review of the articles found 25 original articles for consideration. Several toys were found to be associated with contact dermatitis. These included electronics, toy cars, costume jewelry, bicycles, sqwish balls, slime, Play-Doh, and plasticine. Electronics such as video game controllers, cellphones, iPads, and computers were implicated. In conclusion, there is still an unmet need for observation of this segment of industry for labeling of contents and ongoing surveillance.

Utilizing the McGill Thyroid Nodule Score to compare between hemithyroidectomy cases who required completion thyroidectomy and cases of hemithyroidectomy alone

ObjectivesThis study aims to evaluate whether the McGill Thyroid Nodule Score (MTNS) accurately helps to decide the extent of surgery (hemithyroidectomy versus total thyroidectomy) based on the malignancy risk and to assess whether its use lowers the rate of completion thyroidectomy in cases of indeterminate thyroid nodules.MethodsWe performed a retrospective cohort study comparing MTNS results of patients undergoing hemithyroidectomy in King Abdulaziz Medical City, NGHA, Jeddah from the period of January 2013 to December 2017. We divided the cases into hemithyroidectomy who required completion and hemithyroidectomy who did not need completion surgery. The pre-operative indeterminate FNA biopsy subgroup comprised of Bethesda type III (atypia of undetermined significance/follicular lesion of undetermined significance) and Bethesda type IV (follicular neoplasm/suspicious for a follicular neoplasm/Hurthle cell neoplasm). Post-operative histopathology was divided into benign or malignant groups.ResultsOf the 501 patient charts reviewed, 111 (22.2%) had an indeterminate FNA biopsy. 97 (87.4%) patients were females and 14 (12.6%) were males. In the hemithyroidectomy group, the pre-operative mean of the MTNS was 6.65, while in the completion thyroidectomy the mean was 11.47. The median MTNS was 7 (32% risk of malignancy) for the hemithyroidectomy group and 11 (63% risk of malignancy) for the completion thyroidectomy group (p < 0.001).ConclusionsBased on the MTNS the risk of malignancy in cases of hemithyroidectomy who required completion surgery was significantly higher than those who underwent hemithyroidectomy only. The MTNS can be of value to thyroid surgeon in the pre-operative decision-making when dealing with an indeterminate thyroid nodule on FNA biopsy.     

Platelet-Derived MRP-14 Induces Monocyte Activation in Patients With Symptomatic Peripheral Artery Disease

Background

Peripheral artery disease (PAD), a diffuse manifestation of atherothrombosis, is a major cardiovascular threat. Although platelets are primary mediators of atherothrombosis, their role in the pathogenesis of PAD remains unclear.

Hepatitis B vaccination in human immunodeficiency virus-infected adults receiving hemodialysis

BACKGROUND: The Centers for Disease Control and Prevention (CDC) recommends hepatitis B virus (HBV) immunization for all hemodialysis (HD) patients because they are at high risk of infection. Several studies have shown that the development of protective antibody titers after HBV vaccination is much lower in HD patients. We hypothesized that human immunodeficiency virus (HIV) infection in patients with end-stage renal disease (ESRD) would further impair the immune response to hepatitis B vaccination. METHODS: We performed a retrospective cohort study of patients undergoing long-term hemodialysis from 1990 to 2002 at the United States-based dialysis facilities of Gambro Corporation, North America. The response rate defined as an increase in anti-HBs levels >/=10 mIU/L after a month of the third dose of HBV vaccination was determined in HIV-infected and a randomly selected group of ESRD patients. The demographic information, laboratory data, and hepatitis B surface antibody (anti-HBs) titers were recorded from the Gambro Corporation database on these patients. RESULTS: Of the 347 adult HIV ESRD patients, 116 received three doses of recombinant hepatitis B vaccination. Seventy percent were male, and the majority (86%) were black. Of the 116 patients who received three doses of HBV vaccination, 62 (53.4%) developed protective antibody titers. This was comparable to the response rate of 50.4% in the randomly selected 220 non-HIV hemodialysis patients. Among HIV ESRD patients, the mean hemoglobin (Hgb) was higher in patients who developed protective antibody titers (Hgb 11.61 +/- 2 vs. 10.55 +/- 1.86, P value <0.01). On multivariate logistic regression analysis, higher Hgb was associated with protective antibody titers (odds ratio: 1.34, 95% CI 0.99-1.72). Seventy percent of the HIV-infected responders maintained protective antibody titers 6 months after vaccination. CONCLUSION: Hepatitis B vaccination should be offered to all HIV-infected ESRD patients because over half of the patients with HIV and ESRD can develop protective antibodies.
