Current advances in cancer therapy have increased survival, emphasizing the need for life quality improvement. Fertility loss is common post-chemotherapy. Current guidelines establish embryo and oocyte cryopreservation to address premature ovarian insufficiency (POI). Ovarian tissue cryopreservation has also recently become an acceptable option for fertility preservation, particularly as it is the only option for pre-pubertal patients. Few definitions for optimum fertility outcomes, and few systematic reviews comparing embryo, oocyte, and ovarian tissue cryopreservation as a means of fertility preservation (FP) in pre- and post-pubertal female cancer patients exist. This systematic review aims to improve understanding of gonadotoxic effects of chemoradiation therapy in cancer patients, to analyze the different fertility preservation techniques and procedures available to women with chemoradiation induced ovarian insufficiency, and to compare and recognize the benefits of each technique in restoring fertility, sexual hormone function, and quality of life. Searches were conducted electronically on PubMed, Cochrane, and EBSCOHost, including clinical trials, prospective, and retrospective studies of female cancer patients undergoing anti-cancer therapy, with predefined MeSH terminology. Data were collected, analyzed, and compared. Non-randomized clinical studies were evaluated for risk bias through the Newcastle–Ottawa Scale. In total, 23 studies were included. From there, 647 patients opted for oocyte cryopreservation, 267 for embryo cryopreservation, and 1382 for ovarian tissue cryopreservation (OTC). A total of 175, 18, and 121 live births resulted respectively from oocyte, embryo, and OTC, respectively. Studies without live births discussed other fertility markers as indicators of improvement in sexual hormone function and fertility. The gonadotoxic effects of chemotherapy call for FP intervention. Oocyte and embryo cryopreservation/implantation are well-established procedures. With changing trends and life quality consideration, OTC is a promising interventional method for pre-pubertal patients facing the prospect of fertility loss.

Intestinal spirochetosis is a gastrointestinal infection with vague and inconsistent symptoms. It similarly presents multiple gastrointestinal diseases such as inflammatory bowel disease and appendicitis. We present a case of a 27-year-old female with intestinal spirochetosis who was later found to have subacute appendicitis. Further understanding of the disease and a set of criteria may have to be created for its management.

Fibroepithelial polyps (FEP) of the urinary tract are benign tumors that can cause ureteropelvic junction obstruction (UPJO) in pediatric patients. FEP present a significant diagnostic challenge due to their nonspecific symptoms. This narrative review summarizes recent findings on FEP in children. Diagnostic imaging, including ultrasound, computed tomography, and intravenous pyelography, play a critical role in identifying FEP, although limitations exist in differentiating FEP from malignant tumors. Treatment approaches vary based on the polyp’s size and location, ranging from surgical excision to minimally invasive techniques. Further research is needed to enhance diagnostics and treatment, ultimately improving patient outcomes. Graphical abstract
