Primary adrenal mantle cell lymphoma mimicking a non-functional retroperitoneal paraganglioma.

Key Clinical Message: Patients presenting with abdominal pain and retroperitoneal mass in radiographic images may be in the early stages of primary adrenal mantle cell lymphoma, which requires histological studies for a definite diagnosis.

Abstract: This report presents a 37-year-old woman complaining of ambiguous abdominal pain, with imaging findings revealing a retroperitoneal abdominal mass on the left side of the aorta, and a possible diagnosis of non-functional retroperitoneal paraganglioma. Total laparoscopic excision was performed.

Effectiveness of the oral Clonidine as a pre-anesthetic medicine for thyroidectomy surgery; A randomized clinical trial.

Introduction: Hemodynamic disturbance is a common problem in patients undergoing thyroid surgery. It may be due to episodic increases in thyroid hormones (thyroid storm) or stimulation of the carotid sinus baroreflex. The aim of the present study was to investigate effectiveness of the pre-operative oral Clonidine on reducing these hemodynamic changes during total thyroidectomy surgery.

Exosomes carrying immune checkpoints, a promising therapeutic approach in cancer treatment.

Exosomes are a subgroup of extracellular vesicles generated by distinct cells. Tumor-derived extracellular vesicles convey immunological checkpoint molecules. TEXs as critical mediators in tumor development, metastasis, and immune escape have recently become the focus of scientific research.

Objective: The purpose of this study was to compare the therapeutic effects of a pigtail catheter with a chest tube in the management of patients with spontaneous pneumothorax (SP).

Material And Methods: A randomized controlled trial study was performed on patients with SP from August 2016 to December 2017 at Imam Reza Hospital, Tabriz, Iran. Forty-four patients were randomly assigned into 2 groups: group A with a 14-Fr pigtail catheter and group B using a 28-Fr chest tube.

Comparison of end-to-side hand-sewn and side-to-side stapled cervical esophagogastric anastomosis in patients with lower thoracic esophageal cancer undergoing transhiatal esophagectomy: an Iranian retrospective cohort study.

Background: Controversies in terms of efficacy and postoperative advantages surround stapled esophagogastric anastomosis compared with the hand-sewn technique as a treatment for patients with esophageal cancer. The purpose of this study was to compare the clinical outcomes of hand-sewn end-to-side esophago-gastrostomy and side-to-side stapled cervical esophagogastric anastomosis after esophagectomy for the aforementioned patients.

Methods: This retrospective cohort study involved examining the medical records of 433 patients who underwent transhiatal esophagectomy for esophageal cancer from March 2010 to March 2016.

Preoperative Vitamin D Supplementation in Patients With Vitamin D Deficiency Undergoing Total Thyroidectomy.

Background: Transient hypocalcemia due to parathyroid gland or vessel manipulation is a common complication following thyroidectomy. Considering the role of 25-hydroxyvitamin D (25(OH)D) in calcium hemostasis, this study aimed to evaluate the effect of preoperative vitamin D supplementation on hypocalcemia incidence in thyroidectomy patients.

Methods: In this randomized clinical trial, 100 patients scheduled for total thyroidectomy and suffering from preoperative moderate or severe vitamin D deficiency were enrolled.

The Role of Immunohistochemistry Studies in Distinguishing Malignant Mesothelioma from Metastatic Lung Carcinoma in Malignant Pleural Effusion.

Background And Objective: Early diagnosis of malignant pleural mesothelioma (MPM) is the key point of its treatment. The main problem is the precise diagnosis of mesothelioma and its differentiation from metastatic lung adenocarcinoma. Mesothelioma exhibits complex immunohistochemical characteristics.

Randomized controlled trial on the comparison of chest tube drainage and needle aspiration in the treatment of primary spontaneous pneumothorax.

Objectives: To evaluate the efficacy of the chest tube drainage (CTD) and the needle aspiration (NA) in the treatment of primary Spontaneous pneumothorax (SP).

Methods: In a randomized controlled trial, seventy patients suffering SP were divided equally into two subgroups, as follows: (A) CTD and (B) NA. The immediate and one-week rate of the treatments was the primary endpoints.

Comparing postoperative complication of LigaSure Small Jaw instrument with clamp and tie method in thyroidectomy patients: a randomized controlled trial [IRCT2014010516077N1].

Background: LigaSure® Small Jaw (LSJ) has been recently introduced as an energy-based vessel sealing device, which has provided better intraoperative and postoperative outcomes in thyroidectomies, compared to conventional technique. In the current study, we aimed to examine the efficiency of hand-sewn and LSJ thyroidectomy, based on operation time and perioperative complications.

Methods: All patients with the diagnosis of multinodular goiter, thyroid cancers, retrosternal goiter and other indications for thyroid surgeries, enrolled.

Predisposing factors for seroma formation in patients undergoing thyroidectomy: Cross-sectional study.

Introduction: Seroma is defined as collection of fluid within the surgical site during postoperative period that causes several complications. Recognition of predisposing risk factors can lead to avoid seroma formation after thyroidectomy.

Materials And Methods: A cross-sectional study was carried out during a 3-year period and 678 patients were enrolled the study.

Axillary Lymph Node Metastasis in Medullary Thyroid Carcinoma: A Case Report.

Introduction: Medullary thyroid cancer (MTC) is an uncommon neoplasm originating from parafollicular C cells. Distant metastasis in MTC, such as axillary node involvement, is extremely rare.

Case Report: The present study describes a known case of MTC with axillary lymph node metastasis in a 31-year-old woman.

Combination of intracostal sutures with muscle flap to decrease post thoracotomy pain: A single blinded randomized clinical trial.

Objective: To assess the efficacy of intercostal nerve protection by intercostal muscle (ICM) flap in post-thoracotomy pain improvement compared to intracostal suturing.

Methods: In a randomized controlled trial, ninety-four patients undergoing posterolateral thoracotomy surgery were divided into two subgroups. Intracostal sutures in isolation and in combination with ICM flap techniques were used for thoracotomy closure in both groups.

RET Gene Analysis in Patients with Medullary Thyroid Carcinoma.

Background: Medullary thyroid carcinoma (MTC) is a neuroendocrine tumor from the para follicular C cells of the thyroid gland. It occurs either sporadically or as part of an inherited syndrome. It is caused by an autosomal dominant mutation in the RET (Rearranged during Transfection) proto-oncogene.

An unusual salvage technique for posterior tracheal membranous laceration associated with transhiatal esophagectomy: A transcervical-transsternal approach.

Various surgical approaches may be employed for esophageal resection. Major airway injuries due to transhiatal esophagectomy include vertical tears in the membranous trachea. Tracheal injury is an uncommon but potentially fatal complication.

A huge lymphangioma mimicking pleural effusion with extension to both chest cavities: a case report and review of literature.

Mediastinal lymphangioma is primarily a benign lesion and the majority of the cases are found incidentally. These lesions account for approximately 1% of all mediastinal tumors.
