It has been shown that antibiotic therapy in diabetic foot ulcers has a toxic effect on renal function. Objective: To assess the renal function among patients with diabetes mellitus having diabetic foot infection. Methods: It was a cross-sectional retrospective study in the surgical Unit of DHQ Teaching Hospital KDA Kohat for six-month duration from January 2022 to June 2022. 130 patients with diabetic foot ulcers were selected for this study. The patients receiving antibiotic with a low renal toxicity risk were included in Group-A and patients receiving antibiotics with an increased renal toxicity risk were included in group B. GFR was calculated and measured from Cockcroft-Gault equation and serum creatinine levels. SPSS 20.0 was applied for data analysis with paired t-tests, t-test and chi-square tests. Results: In group A there were 65 (50%) participants and 65 (50%) in group B. GFR after and before antibiotic therapy was 58.30±31.13 cm3 / min and 65.98±35.76 cm3 / min (p = 0.004), correspondingly. The GFR in group B was reduced significantly after antibiotic therapy (p = 0.003). Conclusions: Conferring to this study, renal function decreased and nephrotoxicity was noted after antibiotic treatment, the percentage of decline in GFR being greater in patients who received higher nephrotoxic antibiotics.

Introduction: Breast cancer is one of the most common cancers affecting women worldwide. The prognosis and treatment of breast cancer depend largely on various prognostic factors, including tumour grade, hormone receptor status, and HER2/neu overexpression. Objectives: The main objective of the study is to find the impact of evaluation of tumour grade by core needle biopsy on clinical risk assessment and patient selection for adjuvant systemic treatment in breast cancer Material and Methods: This retrospective cohort study was conducted in Services Hospital, Lahore during January 2020 to January 2021. The study participants were women with breast cancer who underwent core needle biopsy for tumour grade evaluation at a single institution during the study period. Results: Of the 70 patients included in the study, the mean age was 58 years (range, 32-85 years), and the majority were postmenopausal (60%). Most patients had invasive ductal carcinoma (IDC) (85%), and the remainder had invasive lobular carcinoma (ILC) (15%). Most patients had stage II (45%) or stage III (35%) breast cancer at the time of diagnosis. All patients underwent core needle biopsy for tumour grade evaluation. Conclusion: In conclusion, the study supports the use of core needle biopsy as a reliable method for evaluating tumour grade in breast cancer patients. Further research is needed to evaluate the long-term outcomes of patients who are treated based on tumour grade assessed by core needle biopsy.
