The incidence of retinal detachment in the general population is 0.08%, it has been reported to reach 0.7% or higher following cataract surgery. One of the most important risk factors for retinal detachment is posterior capsular rupture during cataract surgery. Additional risk factors include high myopia, history of ocular trauma, young age, male sex, and diabetes. In this study, we aimed to investigate the incidence and risk factors of retinal detachment following cataract surgery in patients treated at our hospital. Materials and methodsThis retrospective cohort study was conducted at King Abdulaziz University Hospital (KAUH), a tertiary center in Jeddah, Saudi Arabia. The medical records of 365 patients (365 eyes) who underwent cataract surgery from 2017 to 2021 were reviewed. ResultsThe average age of the 365 patients was 63 years, and 47.7% (n=174) of patients were male. The incidence of retinal detachment was 3.3% (n=12). The risk of RD was 2.8 times higher for the right eye than for the left eye. The incidence of RD was significantly more in eyes with intraoperative posterior capsular rupture, zonular dehiscence, corneal trauma, and surgery combined with anterior vitrectomy than in other eyes. The most common complication of cataract surgery is corneal edema, which was observed in 22.7% of the eyes; our analysis revealed a significant relationship between corneal edema and the duration of surgery. ConclusionIn our study, we highlighted the higher incidence of retinal detachment compared to those in other studies; most cases occurred one month postoperatively.

Introduction: Pruritus is a common and bothersome symptom in chronic kidney disease patients, particularly those on dialysis. We aimed to establish the prevalence of pruritus among renal dialysis patients in King Abdulaziz University Hospital and assess its relationship with dietary consumption and laboratory findings. There has yet to be any similar research conducted in this area. Methodology: This was a cross-sectional study started from January to November 2022 during dialysis, 44 patients were interviewed and analyzed in a dialysis clinic. Any patient under the age of 18 was excluded. Pearson's chisquare test, Fisher's exact test and t-test were used to determine the connection between the variables. Results: Pruritus was present in 40.9% of the participants, with an average scale of 4.9/10. The biochemical indicators of kidney function were analyzed quantitatively, in which 100% of the participant had a high pre-dialysis and 11.4% had a high post-dialysis urea. In addition, 36.4% had high phosphorus levels, 29.5% had elevated potassium levels, 6.8% had high albumin and 84.1% had appropriate KT/v. There was a strong association between pruritus and pre-creatinine. The mean precreatinine in the presence of pruritus was significantly different from the mean pre-creatinine in the absence of pruritus (P = 0.005). Conclusion: We found that more than 50% of our patients on dialysis did not have pruritus.Moreover, there was insignificant relationship between dietary intake and pruritus. On the other hand, we discovered a substantial rise in the biochemical marker creatinine and pruritus, which was strongly present in our patients.
