Abstract Objectives: Prostate cancer (PC) is common cancer worldwide. Several markers have been developed to differentiate between benign prostatic hyperplasia (BPH) from PC. A descriptive retrospective hospital-based study aimed at determining the expression of Cyclin D1 in BPH and PC. the study took place at different histopathology laboratories in Khartoum state, Sudan, from December 2016 to January 2019. Formalin-fixed paraffin-embedded blocks were sectioned and fixed in 3-aminopropyltriethoxysilane coated slides incubated into primary antibody for Cyclin D1. The assessment of immunoreactivity of Cyclin D1 of each section was done using the Gleason scoring system. Results: A total of 153 males’ prostate sections included in this study, of them, 120 (78.4%) were PC, and 33 (21.6%) were BPH. Their age ranged from 45 to 88 years, mean age was 66.19 ± 8.599. 142 (92.8%) did not have a family history of PC, while 11 (7.2%) patients reported having a family history. The Gleason scoring showed a total of 81 (52.9%) patients with high-grade and 39 (25.5%) with low-grade. 118 (97.5%) patients had PC showed positive results for Cyclin D1, while BPH was 3 (2.5%). P value < 0.001. Cyclin D1 staining was associated with high-grade Gleason score and perineural invasion, P value 0.001.

Abstract Objectives: Infection with the causative agent of visceral leishmaniasis (VL) may be either symptomatic or asymptomatic. In this study we aimed at investigating the prevalence of asymptomatic infections of leishmania in non-endemic villages in Gedaref state, Sudan. A descriptive cross-sectional study conducted during September and October 2014. Blood samples were collected for serological and molecular analysis. Sticky-traps, knockdown spray and CDC-miniature light traps were used for the collection of sandflies. Results: Ninety-Five participants were included; 52 from Abukishma, 15 Algadamblia Tirfa, 25 Abualnaja and 3 were from Algadamblia Aljabal . Females constituted 56 (58.9%) of the study participants while males were 39 (41.1%). The most frequent age group was >40-years (54.7%). Balanites/Acacia trees were the most planted tree inside the houses; 78 (82.1%). Also, 85 (89.5%) of the participants breed animals inside the house. DAT test revealed 5 positive participants (5.2%). 4/5 DAT positive were past VL infection. PCR detected 35 (36.8%) positive participants. A total of 31/35 was considered asymptomatic infections based on PCR. Households planted Balanites/Acacia trees or breed domestic animals were found in high percentages with L. donovani PCR positive participants (60.1%, 91.4%). No statistically significant was found for VL associated risk factors and VL asymptomatic participants.

Abstract Objectives Visceral Leishmaniasis (VL) can be symptomatic and asymptomatic infection. In this study we aimed at investigating the prevalence of asymptomatic infections and to study risk factors of VL in non-endemic regions in Gedaref state, Sudan. A descriptive cross-sectional study conducted during 2014. Blood samples were collected to serological and molecular analysis. Sticky traps, knockdown spray and CDC miniature light traps were used for the collection of sandflies. Results Ninety-Five participants were included; 52 from Abukishma, 15 Algadamblia Tirfa, 25 Abualnaja and 3 were from Algadamblia Aljabal. Most of the study participants were belonging to the Belala tribe (74.3%). The most frequent reported age was above 40-years old (9.5%). Females were (61.1%) and males were (38.9%). B. aeygptica was the most planted tree in/around the houses (46.3%). 73 (76.8%) of the participants bred more than two types of animals in the house. DAT test revealed 5 positive participants (5.2%). 4/5 DAT positive were past VL infection. PCR detected 35 (36.8%) positive patients. A total of 31 (32.6%) were considered asymptomatic infections based on PCR detection method. Households planted Balanites/Acacia trees or breed domestic animals were found in high percentages with VL PCR positive participants (60.1%, 91.4%).
