Pars plana vitrectomy is a well developed and widespread used surgical technique with several instruments and special tools for selected vitreoretinal cases. Knowledge of complications during the various steps of the surgical procedure make easier to avoid them. Most important is first to collect experiences with simple cases and to get accustomed to the otherwise special surgical technique that needs good cooperation of the surgeons two hands, two feet and needs steady attention on the tips of the intraocular instruments. However, after certain experience complications will occur because of the complicated cases of proliferative diabetic retinopathy or other vitreoretinal diseases.

Asian Pac J Cancer Prev
January 2025
Department of Pathology, Faculty of Medicine, Mansoura University, Mansoura, Egypt.
Objective: Programmed Death-Ligand 1 (PD-L1) and Cytotoxic T Lymphocyte -Associated Antigen-4 (CTLA-4) are presently considered as prognostic markers and therapeutic targets in numerous human malignancies. The goal of this study was to determine whether PD-L1 and CTLA-4 might be used to predict patients' survival in Triple Negative Breast Cancer (TNBC).
Methods: This retrospective cohort study analyzed 100 primary TNBC cases that had surgical resection at the Oncology Center of Mansoura University (OCMU), Faculty of Medicine, Egypt.

Department of Anesthesiology and Resuscitology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University, Okayama, Japan.
Objective: This study aimed to clarify whether nutritional status at admission affects enteral nutrition weaning 6 months after surgery in patients with esophageal cancer.
Methods: This was a retrospective study of 81 patients who underwent subtotal esophageal cancer resection between April 2014 and February 2016. The survey items were as follows: 1) sex, 2) age, 3) presence or absence of family members living together, 4) clinical stage, 5) surgical procedure, 6) reconstructed organs, 7) nutritional status at admission, 8) presence or absence of postoperative complications (anastomotic leakage, chylothorax, and recurrent laryngeal nerve paralysis), and 9) presence or absence of treatment other than surgery (chemo- or radiotherapy).

Division of Hematology and Medical Oncology, Udayana University, Prof. I.G.N.G Ngoerah General, Badung, Bali, Indonesia.
Objectives: To explore the significance of diminished CD3/CD8 and CD3/CDR45RO immunoscores, as well as elevated FOXP3 expression, as potential risk factors for unfavorable responses to neoadjuvant chemotherapy among patients with triple-negative breast cancer (TNBC).
Methods: A case-control study was conducted across two hospitals (a public and a private facility) from August 1st, 2021, to August 31st, 2022. The study population comprised patients diagnosed with the TNBC subtype, with available paraffin blocks from biopsy procedures.
