Leiomyomas are the most common pelvic tumors. Submucosal fibroids are a common cause of abnormal bleeding and infertility. ⋯ Several techniques have been introduced over time and will be covered in depth in this manuscript. Advances in optics, fluid management, electrosurgery, smaller diameter scopes, and tissue removal systems, along with improved training have contributed to improving the safety and efficiency of hysteroscopic myomectomy.

Case Reports
A Fatal Case of Chlorfenapyr Poisoning and the Therapeutic Implications of Serum Chlorfenapyr and Tralopyril Levels.
Chlorfenapyr is a new contact and stomach insecticide derived from natural pyrroles secreted by Streptomyces spp. It is a pro-insecticide and acts after metabolic transformation to its active metabolite tralopyril. Tralopyril is an uncoupler of oxidative phosphorylation in the mitochondria of the target insects and of experiment animals, leading to the disruption of adenosine triphosphate synthesis and death. ⋯ The serum levels of tralopyril were 723.6, 14,179, and 9654.2 ng/mL at 4, 113, and 156 h post-ingestion, respectively. The delay in the rise of serum tralopyril levels was noticeable, which seems to correlate with the patient's signs and symptoms. The information may have therapeutic implications in the management of this deadly poisoning.

Background and Objectives: Oxytocin (OT) is a neuropeptide hormone which is known for its classical effects in pregnancy and lactation. Recently, growing evidence demonstrated a close relation between OT and bone. The present study aimed to explore the relationship between OT, bone and osteoporosis risk in Chinese adult females. ⋯ Conclusion: Our study demonstrated positive associations between serum OT levels and BMD in a Chinese (non-Caucasian) population. OT appeared to be more strongly associated with hip BMD in premenopausal females. These results may suggest a protective role and potential therapeutic use of OT in osteoporosis, especially for premenopausal women.

Background and Objectives: Considering the significant number of patients worldwide that received empirical antibiotic therapy for COVID-19 infection due to their critical condition and the lack of therapeutical guidelines, we wanted to find out the consequences of antibiotic use in our study population. Materials and Methods: We conducted a retrospective cohort study including symptomatic patients older than 18 years, hospitalized for SARS-CoV-2 between March and December 2020 in the Internal Medicine and Pneumology Departments of Colentina Clinical Hospital. The elected outcome was death, while independent variables were antibiotic therapy and literature-cited parameters associated with mortality in this disease. ⋯ Female gender (OR = 2.61, p = 0.04), history of neoplasm (OR = 7.147, p = 0.01), heart failure (OR = 8.62, p = 0.002), and diabetes mellitus (OR = 3.05, p = 0.02) were significantly associated with death in multivariate analysis. Antibiotic treatment showed a higher probability of death both in bivariate (OR = 5.333, p < 0.001) and multivariate analysis adjusted for the aforementioned prognostic factors (OR = 3.55, p = 0.01). Conclusions: After adjusting for confounders, in-hospital antibiotic administration did not improve survival in COVID-19 patients.

Background: Interleukin (IL)-17A and IL-17F, expressed mainly by a novel subset of CD-positive (+) T-helper (Th) cells of the immune system, has been closely related to inflammatory conditions underlying colorectal cancer pathogenesis. Accordingly, we conducted a case-control study to investigate the association of common single nucleotide polymorphisms (SNP) in the IL17A and IL17F genes (rs2275913 and rs763780, respectively) with the susceptibility and severity of CRC patients from the Bulgarian population. Methods and Materials: 136 patients with histologically confirmed CRC diagnosis and 116 healthy individuals were recruited in the present study. ⋯ Among the patients with detected distant metastases, the A/G-carriers were the smallest part (14.3%) compared to the homozygous genotypes A/A (42.9%) and G/G (42.8%), p = 0.006. There was no association of the studied IL17F rs763780 SNP with susceptibility and severity of CRC among the studied subjects, although the heterozygous C/T-carriers had shorter median survival compared to the T/T-carriers (p = 0.129). Conclusions: Our study finds a protective role of heterozygosity for the IL17A-197A/G SNP and negative effects of the A-allele on CRC progression.
