This study was performed to determine the comparative efficacy of paracetamol alone versus paracetamol plus ondansetron on acute postoperative pain after abdominal surgeries in Azad University hospitals in 2017 and 2019. In this randomized clinical trial, 62 consecutive patients under abdominal surgeries, were randomly divided into two groups, group 1 patient who received paracetamol alone 1 gram and group 2 patient who received paracetamol 1 gram plus 4 mg ondansetron and the pain severities were determined and compared between groups at recovery and after 4 and 24 hours. The results of this study revealed that there were no statistically significant differences between two groups for the postoperative pain severity and analgesic use ( p > 0.05). It may be concluded that addition of ondansetron to paracetamol would not result in further postoperative pain reduction and additive use of this drug is not recommended.

Background  Central compartment lymph node dissection (CLND) is a part of the surgical management of differentiated thyroid cancer (DTC). Therapeutic CLND is done to address clinically significant central compartment nodes in patients with DTC, while prophylactic CLND is performed in the presence of high-risk features in the absence of clinically significant neck nodes. Removal of thymus-unilateral or bilateral-during CLND to achieve complete clearance of level VI and VII lymph node stations and address thymic metastasis is debatable. Objective  The present systematic review was conducted to summarize the evidence, delineating the role of thymectomy during CLND in patients with DTC. Methods  Electronic databases of PubMed, Embase, and Cochrane were searched from their inception to July 2020 using keywords-thyroid neoplasms or tumors, thyroidectomy, and thymectomy-to identify the articles describing the role of thymectomy during CLND in DTC. A pooled analysis of surgicopathological outcomes was performed using metaprop command in STATA software version 16. Result  A total of three studies and 347 patients-total thyroidectomy (TT) with bilateral thymectomy in 154, TT with unilateral thymectomy in 166, and TT alone in 27 patients with DTC-were included in the systematic review. The pooled frequency of thymic metastasis was a mere 2% in patients undergoing either unilateral or bilateral thymectomy. The routine addition of thymectomy does not result in better lymph node clearance. Unilateral and bilateral thymectomy were associated with high chances of transient hypocalcemia (12.0% and 56.1%, respectively). Conclusion  Routine thymectomy is not warranted during CLND, considering minimal oncological benefit and high risk of postoperative hypocalcemia.

Recently, radical vaginal hysterectomy (RVH) has developed into laparoscopically assisted radical vaginal hysterectomy (LARVH), which is associated with the laparoscopical procedure, and it is applied as radical vaginal trachelectomy and semi-radical vaginal hysterectomy. LARVH is indicated for patients with stage IB1 and IIA1 cervical carcinoma, especially those with a tumor size of less than 2 cm, because the cardinal ligaments cannot be resected widely. Although RVH that is associated with laparoscopic pelvic lymphadenectomy is the most used surgical procedure, radical trachelectomy may be performed either abdominally or vaginally (laparoscopic or robotic). One report found that the pregnancy rate was higher in patients who underwent minimally invasive or radical vaginal trachelectomy than in those who underwent radical abdominal trachelectomy.

Robotic surgery is considered to be the optimal means of performing nerve-sparing radical hysterectomy (RH) because this procedure requires very precise surgery. Nerve-sparing RH has become increasingly popular in Japan. However, with open surgery the operating field is only visible to the surgeon performing this delicate procedure, which makes it difficult to educate trainee assistants. However, robotic surgery provides an expanded operation field that is visible to the surgeon and assistants, which makes it suitable for teaching purposes. To perform this procedure, it is necessary to become proficient in RH by laparotomy and then to become familiar with the characteristics of robotic surgery. In shifting from laparotomy to robotic surgery, we have found that experience with open surgery does not fully prepare surgeons for the new experiences and discoveries associated with robotic surgery, which may initially be problematic. We here provide clear instructions for the procedure with notes concerning particular potentially problematic aspects.

Radical hysterectomy (RH) is a standard treatment for early-stage cervical cancer. This surgery extirpates the uterus along with the paracervical tissues, vagina, and the paracolpium to achieve local control. Pelvic lymphadenectomy is a critical component of RH performed for regional control. A clear understanding of pelvic anatomy is critical to safely performing a RH and achieving optimal oncological and functional outcomes. The various surgical steps can damage the pelvic autonomic nerves, and a systematic nerve-sparing technique is used for the preservation of autonomic nerves. There is an intricate vascular network in the lateral paracervix (cardinal ligament) and the pelvic sidewall. We need to comprehend the three-dimensional structure of the vascular and nerve anatomy in the pelvis to perform RH effectively and safely. We can create six spaces around the uterine cervix, including the paravesical spaces, pararectal spaces, a vesicovaginal space, and a rectovaginal space to reveal the target of extirpation. It is critical to find the proper tissue plane separated by the layers of membranous connective tissue (fascia), in order to minimize intraoperative bleeding.

Food handlers and workers are exposed to several occupational hazards not frequented by the general population. Grinder injuries of the hand present a devastating consequence of industrial food processing that is infrequently described. Herein, we describe two cases that presented to our department with meat grinder injuries of the hand.

Background  Trauma-related injury causes higher mortality than a combination of prevalent infectious diseases. Mortality secondary to trauma is higher in low- and middle-income countries (LMICs) than high-income countries. This review outlines common issues, and potential solutions for those issues, identified in trauma care in LMICs that contribute to poorer outcomes. Methods  A literature search was performed on PubMed and Google Scholar using the search terms "trauma," "injuries," and "developing countries." Articles conducted in a trauma setting in low-income countries (according to the World Bank classification) that discussed problems with management of trauma or consolidated treatment and educational solutions regarding trauma care were included. Results  Forty-five studies were included. The problem areas broadly identified with trauma care in LMICs were infrastructure, education, and operational measures. We provided some solutions to these areas including algorithm-driven patient management and use of technology that can be adopted in LMICs. Conclusion  Sustainable methods for the provision of trauma care are essential in LMICs. Improvements in infrastructure and education and training would produce a more robust health care system and likely a reduction in mortality in trauma-related injuries.

Background  Surgical treatment of posttraumatic defects of the knee joint is challenging. Osteochondral allograft reconstruction (OCAR) is an accepted procedure to restore the joint congruity and for pain relief, particularly in the younger population. Preoperative three-dimensional (3D) planning and patient-specific instrumentation (PSI) are well accepted for the treatment of posttraumatic deformities for several pathologies. The aim of this case report was to provide a guideline and detailed description of the preoperative 3D planning and the intraoperative navigation using PSI in OCAR for posttraumatic defects of the tibia plateau. We present the clinical radiographic results of a patient who was operated with this new technique with a 3.5-year follow-up. Materials and Methods  3D-triangular surface models are created based on preoperative computer tomography (CT) of the injured side and the contralateral side. We describe the preoperative 3D-analysis and planning for the reconstruction with an osteochondral allograft (OCA) of the tibia plateau. We describe the PSI as well as cutting and reduction techniques to show the intraoperative possibilities in posttraumatic knee reconstructions with OCA. Results  Our clinical results indicate that 3D-assisted osteotomy and OCAR for posttraumatic defects of the knee may be beneficial and feasible. We illustrate the planning and execution of the osteotomy for the tibia and the allograft using PSI, allowing an accurate anatomical restoration of the joint congruency. Discussion  With 3D-planning and PSI the OCAR might be more precise compared with conventional methods. It could improve the reproducibility and might allow less experienced surgeons to perform the precise and technically challenging osteotomy cuts of the tibia and the allograft. Further, this technique might shorten operating time because time consuming intraoperative steps such as defining the osteotomy cuts of the tibia and the allograft during surgery are not necessary. Conclusion  OCAR of the tibia plateau for posttraumatic defects with 3D preoperative planning and PSI might allow for the accurate restoration of anatomical joint congruency, improve the reproducibility of surgical technique, and shorten the surgery time.
