The Oncologic Outcomes of Bilateral Central Lymph Node Dissection in Unilobar Papillary Thyroid Cancer and Its Risks: A Prospective Cohort Study.

Background Indications for performing a prophylactic central neck dissection (pCND) in papillary thyroid cancer (PTC) remain controversial. Thyroidectomy and central neck dissection (CND) are often recommended in all cases with proven differentiated thyroid cancer (DTC) and clinically positive lymph nodes (LNs), as well as in high risk for micro-metastasis patients with T3-T4 tumors or established metastatic nodes in the lateral compartments. Aims The aims of this study were to ascertain the role of performing bilateral central LN dissection in unilobar PTC in improving the oncological outcomes and outline the risks involved.

Environmental impacts of industrial activities on floral coverage with special emphasis on detoxification enzyme activities in Cataglyphis savignyi as pollution biomarker.

The present study investigates the environmental impact of industrial activities on floral coverage within the major industrial district of Borg El-Arab City, Egypt. Additionally, it aims to evaluate the detoxification enzymatic activity of Cataglyphis savignyi as a pollution biomarker. To achieve this objective, seasonal soil samples were collected from the studied sites to determine soil properties and heavy metal concentrations.

Independent predisposing factors for subcutaneous and deep wound collection after total thyroidectomy, a prospective cohort study.

Background: The literature contains diverse and sometimes contradicting results about wound seroma following thyroidectomy. This is probably due to the subjective clinical estimation of seroma, or due to failure to differentiate between the occurrence of subcutaneous (SC) and deep wound collections. This work aimed at objectively investigating the factors affecting subcutaneous and deep wound seroma after thyroidectomy.

Level I lymph node involvement in patients with N1b papillary thyroid carcinoma: a prospective study.

Most of the studies on the incidence, pattern, and predictive factors of lymph node (LN) metastasis with papillary thyroid carcinoma (PTC) have been performed retrospectively and no common consensus has been reached regarding the predictors for the involvement of level I LNs. This study was conducted prospectively to determine the incidence and the possible predictors of level I involvement in N1b PTC patients. The study included 30 consecutive patients with N1b stage of PTC.

Endoscopic Variceal Ligation followed by Argon Plasma Coagulation Against Endoscopic Variceal Ligation Alone: A Randomized Controlled Trial.

Goals: Our aim was to study the efficacy and the safety of argon plasma coagulation (APC) in secondary prophylaxis against esophageal varices in view of many contraindications and side effects to β-blockers in cirrhotic patients.

Background: Rebleeding rates from esophageal varices after endoscopic variceal ligation (EVL) are high; thus, the current recommendation is to combine nonselective β-blockers to it, but side effects and relative contraindications to nonselective β-blockers hinder their usage or require discontinuation in 15% to 20% of the cirrhotic patients. Thus, it is important to find another combination.

Four-arm randomized trial comparing laparoscopic and open hernia repairs.

Aim: To compare four approaches in primary repair of inguinal hernia as regards operative and postoperative outcome.

Methods: One hundred consecutive patients with primary inguinal hernia Nyhus I-III were randomized into four groups. Group I had open pro-peritoneal repair, group II had Lichtenstein tension-free mesh repair, group III had Transabdominal pro-peritoneal (TAPP) repair while group IV had laparoscopic totally extraperitoneal (TEP) hernia repair.

Video-assisted submandibular resection: two-step technique.

Background: The relative delay in the development of endoscopic neck surgery has been attributed to the relatively narrow operative field and to the presence of many vital structures in it. For endoscopic neck surgery to be feasible, it is essential to create a comfortable working space. A method of creating a working space is the gasless skin-lifting technique.
