Fortunately, gynecologists are enthusiastically embracing diagnostic and operative hysteroscopy as a means to evaluate women with menstrual disorders, infertility, post-menopausal bleeding, recurrent pregnancy loss, and for ultrasound images. In general, operative hysteroscopy is a safe procedure, is easily learned, and has excellent surgical outcomes. As more obstetricians/gynecologists perform hysteroscopy, they must remain cognizant about the salient complications. The recognition of complications and prompt intervention will prevent adverse sequelae as well as minimizing undesirable patient outcomes and reducing legal risks. Hysteroscopy remains a relatively safe procedure. Diagnostic hysteroscopy has the fewest risks, followed by operative hysteroscopic adhesiolysis, metroplasty, and myomectomy. Fluid management is critical for intraoperative safety. Meticulous detail should be paid to fluid management, and consultation sought with a critical care specialist when fluid overload or hyponatremia is suspected. Lingering pain, fever, or pelvic discomfort after surgery requires prompt evaluation. Women becoming pregnant after operative hysteroscopic procedures need careful antepartum and intrapartum care. Special attention to unusual pain complaints during pregnancy or with fetal distress in labor need prompt intervention. The preoperative use of misoprostol or laminara decreases the risk of uterine perforation. Expert preoperative evaluation is essential in determining the surgical skill and expertise needed, surgical time, and the likelihood of completing the operative procedure. Overall, complications in operative hysteroscopy are infrequent and are usually easy to manage. This knowledge should help physicians perform more procedures.

Copper oxide and Zinc (Zn)-doped Copper oxide nanostructures (CuO-NSs) are successfully synthesized by using a hydrothermal technique. The as-obtained pure and Zn-doped CuO-NSs were tested to study the effect of doping in CuO on structural, optical, and antibacterial properties. The band gap of the nanostructures is calculated by using the Tauc plot. Our results have shown that the band gap of CuO reduces with the addition of Zinc. Optimization of processing conditions and concentration of precursors leads to the formation of pine needles and sea urchin-like nanostructures. The antibacterial properties of obtained Zn-doped CuO-NSs are observed against Gram-negative (Pseudomonas aeruginosa, Klebsiella pneumonia, Escherichia coli) and Gram-positive (Staphylococcus aureus) bacteria via the agar well diffusion method. Zn doped s are found to have more effective bacterial resistance than pure CuO. The improved antibacterial activity is attributed to the reactive oxygen species (ROS) generation.

While the consumption of seaweed and seaweed-based products is very common amongst East Asian nations, forming a notable component of the daily diet, relatively very few studies have concerned the concentrations of heavy metals in these together with potential effects on human health. The present study analyses the concentrations of 17 elements in locally resourced seaweed, also assessing potential noncarcinogenic and carcinogenic risks. The samples were ground, homogenized, and quantified using the ICP-OES technique. It has been found that the essential elements K, Ca, Mg, Zn, and Na typically show concentrations somewhat greater than a number of potentially toxic metals, in particular, Cd, Pb, Ag, and As, with exceptions being Ni, Cr-VI, and Si. Statistical analysis indicates all of the latter to have similar origin, with increased concentration of these metals within the marine ecosystem. While the daily estimated intake of most metals is seen to be within the daily dietary allowance level recommended by various international organizations, the noncarcinogenic risk shows a value greater than unity, estimated via the hazard quotient. This indicates a potential for adverse effects to health arising from consumption of the sampled seaweed. The carcinogenic risk resulting from nonessential elements shows values greater than the United States Environmental Protection Agency (US-EPA) reference limit of 10⁻⁴. Considering the nonbiodegradability of heavy metals and metalloids and their potential accumulation in seaweed, there is need for critical examination of metal levels in the seaweeds obtained from the present study locations, together with the introduction of practices of removal of heavy metals via bio-adsorbent techniques.
