Penile Epidermal Inclusion Cyst

We report a case of epidermal inclusion cyst in a 32-year-old male. This was a complication of circumcision that was neglected over years to form stones and urethrocutaneous fistula. Complete excision of the cyst and repair of the fistula were performed successfully. Histopathological examination confirmed our diagnosis

Forecasting Stock Market Volatility Using Hybrid of Adaptive Network of Fuzzy Inference System and Wavelet Functions

This study aims to model and enhance the forecasting accuracy of Saudi Arabia stock exchange (Tadawul) data patterns using the daily stock price indices data with 2026 observations from October 2011 to December 2019. This study employs a nonlinear spectral model of maximum overlapping discrete wavelet transform (MODWT) with five mathematical functions, namely, Haar, Daubechies (Db), Least Square (LA-8), Best localization (BL14), and Coiflet (C6) in conjunction with adaptive network-based fuzzy inference system (ANFIS). We have selected oil price (Loil) and repo rate (Repo) as input values according to correlation, the Engle and Granger Causality test, and multiple regressions. The input variables in this study have been collected from Saudi Authority for Statistics and Saudi Central Bank. The output variable is obtained from Tadawul. The performance of the proposed model (MODWT-LA8-ANFIS) is evaluated in terms of mean error (ME), root mean square error (RMSE), and mean absolute percentage error (MAPE). Also, we have compared the MODWT-LA8-ANFIS model with traditional models, which are autoregressive integrated moving average (ARIMA) model and ANFIS model. The obtained results show that the performance of MODWT-LA8-ANFIS is better than that of the traditional models. Therefore, the proposed forecasting model is capable of decomposing in the stock markets

A Case of Complete Renal Duplex with H-Shaped Ureter

We present a case of complete renal duplex with H-shaped double ureter opening into the bladder with 2 separate orifices. It is an extremely rare variety of renal duplex which was reported only once in the literature. Fifty-four-year-old male presented to our department with right renal pain. Noncontrast CT revealed stone midthird right ureter with duplex right kidney. Retrograde ureteropyelography and ureteroscopy revealed this rare anomaly

Toxoplasma gondii infection among pregnant women attending maternity clinics; multi center experience from Riyadh Region, Saudi Arabia

Introduction: Toxoplasma gondii infection in pregnant women is linked with higher risk of spontaneous abortion or premature infants. This study aims to investigate the seroprevalence of T. gondii infection in pregnant women in Riyadh, Saudi Arabia. Material and Methods: 1000 blood samples were collected from women visiting various regional laboratories of Riyadh. Serum was tested for toxoplasmosis using ELISA technique. Results: The result revealed that 93% pregnant women were serologically negative and only 7% were positive. The study concludes that youngand aged women who have T. gondii infection should have more awareness about this infection and its complications. Conclusion: The study would be valuable in improving pregnancy care by encouraging the health workers to implement clinical and protective care plans side by side
