Is acute appendicitis more severe in foreign workers of northern Israel? A retrospective cohort study.

BACKGROUND: Acute appendicitis (AA) is one of the most common surgical emergencies worldwide. It's classified into simple or complicated disease. Due to the high prevalence of the disease, AA has been studied as a marker to assess the quality of care afforded to minority groups. The purpose of this study was to compare AA outcomes in foreign workers (FW) to the general population in northern Israel. METHODS: This is a retrospective cohort study. We identified all patients aged 18-50 who were admitted to our institution between January 1st, 2013 and October 31st, 2018, with the diagnosis of acute appendicitis. The study group included all FW and the control group included citizens of Israel. Study patients were matched based on age, sex, and co-morbidities. We compared time to presentation, admission parameters and disease outcomes. Our study outcomes were disease severity and length of hospital stay. RESULTS: We identified 20 FW and 97 matched local patients. FW presented with significantly higher heart rate, temperature, and white blood cell count (WBC). Duration of symptoms was comparable between the two groups. The rates of complicated disease were significantly higher among FW (45 vs 17.5%, p < 0.0001). Length of hospitalization was significantly longer in the FW group (4.8 vs. 3.9 days, p = 0.01). The odds ratio of FWs for having a complicated disease was OR = 3.85 [95% CI: 1.38, 10.72], p = 0.01. Multivariate analysis identified FW and duration of symptoms as significantly contributing to a complicated disease outcome. CONCLUSIONS: Although duration of symptoms was comparable to the local population, FW in northern Israel are at increased risk for a complicated disease which resulted in longer hospital stay. Further studies may enlighten the reason for this disparity.

Is there a correlation between meatal stenosis severity, lower urinary tract symptoms and uroflowmetry?

INTRODUCTION: We have recently validated a meatal Stenosis (MS) severity grading system that is based on physical examination. OBJECTIVES: The study objective was to examine the correlation between this grading system, patients' urinary symptoms, uroflowmetry and postvoid residual parameters. STUDY DESIGN: Patients referred for our clinic for urinary and non-urinary complaints, were prospectively enrolled. Urinary symptoms questionnaire, uroflowmetry parameters and post-voiding residuals (PVR) were assessed, and photographs of the urethral meatus were taken for each patient. The photographs were graded blindly according to the previously validated grading system and correlated with urinary symptoms, uroflowmetry parameters and PVR. RESULTS: Overall, 75 patients were assessed (20 grade 0, 23 grade 1 and 32 grade 2). When using grade 0 as a reference, the odds ratio (OR) for reporting narrow stream was 6.4 (95%CI 1.65-24.77) and 4 (95%CI 1.18-14.16) for grade 1 and 2 respectively. OR for prolonged urination was 6 (95% CI 1.47-24.89) for Grade 1 and 2; OR for upward stream deviation was10.08 (95%CI -2.43-41.82) for grade 1 and 15.12 (95%CI - 3.74-61.17) for grade 2. Uroflowmetry results showed lower Qmax from 16.8(SD ± 8.0) ml/sec in grade 0-9.6 ml/s on grade 1 and 2 (p < 0.001) (Figure 1). PVR was not statistically different in the three groups. DISCUSSION: Our main findings were that meatal stenosis severity grade is associated with narrow stream as reported by parent, prolonged urination, and upward deviation of urinary stream, with increasing severity with worsening stenosis. MS grade was also associated with significant worsening of uroflow measures: a lower Qmax, Qmean and a longer time-to-Qmax. Post-void residual volume was not significantly different between the different severity grades. This study showed the clinical significance of the grading system. With subjective and objective measures. The implementation of this grading system in clinics, may aid in decision making regarding surgical intervention in the appropriate patients, and avoid unnecessary procedures. CONCLUSION: The Severity of MS seen on physical examination correlates well with obstructive symptoms and decrease of urine stream seen on uroflowmetry. These findings confirm the importance of the grading system in the evaluation of patients with MS and may be additional measure that assist in consulting parents on the indications to meatotomy.

Primary small cell type of non-Hodgkin lymphoma of the colon: a case report.

INTRODUCTION: Primary lymphoma of the colon is exceedingly rare and comprises 0.2-1% of all colon tumors. The most common subtype of lymphoma in the colon is non-Hodgkin lymphoma. Symptoms are often nonspecific, and treatment varies between chemotherapy alone and a combination of surgery and chemotherapy. CASE PRESENTATION: We describe a case of a Ashkenazi Jew patient who presented in the typical way that carcinoma of the colon might present but turned out to have a very rare type of tumor in both its histology and its location. CONCLUSION: There was apparent discordance between the relative bulkiness and gross appearance of the tumor with the unrevealing result of the biopsies, demanding a high level of suspicion as to the actual presence and possible type of such a tumor in the future.

Formulation and validation of meatal stenosis grading system.

INTRODUCTION: Meatal stenosis (MS) is a common finding in circumcised children. Indication for surgical correction is based on urinary symptoms such as strength and direction of urine stream as well as physical examination, including direction and caliber of the urinary stream. There is no objective grading of MS severity, and therefore indications for surgery and management protocols are vague. OBJECTIVE: We aimed to formulate a standardized, validated, and reliable grading system for MS severity based on the physical examination finding. STUDY DESIGN: Photographs of the urethral meatus were taken in patients scheduled for meatotomy due to MS, whereas patients without this condition served as control. The photographs were rated by three experienced fellowship trained pediatric urologists. The study was conducted in two phases: 1) development of a grading system by the expert panel and 2) testing of the proposed grading system for inter- and intra-rater reliability. To estimate the correlation between different rates, the intra-class correlation coefficient (ICC) was calculated. RESULTS: Three grades were generated: Grade 0 (wide open meatus, visible mucosa), Grade 1 (minimal mucosa/fibrotic tissue visible), and Grade 2 (pinpoint meatus/no mucosa visible/large fibrotic layer). A panel of 51 raters (pediatric urologist, community urologist, pediatricians) participated in the survey evaluating the representative photos from 86 patients. Inter-rater reliability was high ICC = 0.99 (95% confidence interval [CI] of 0.983-0.996, P < 0.0001) Cronbach's alpha = 0.992. In total, 18 raters participated in the same survey two weeks later for intra-rater reliability. An identical grading was obtained in 83.3% of photographs (kappa = 0.455 [P < 0.05]). CONCLUSION: We propose a grading system that is a valid, reliable, and reproducible method to classify the severity of MS on physical exam. This grading system could improve the healthcare provider's and parent's communication and can be a building block for further research in this field. A further research should assess the correlation with clinical signs and symptoms.
