Abdominal Wall Thickness Predicts Surgical Site Infection in Emergency Colon Operations.

J Surg Res 2021 Jun 12;267:37-47. Epub 2021 Jun 12.

Division of Trauma, Emergency Surgery, and Surgical Critical Care, Massachusetts General Hospital, Boston, Massachusetts; Harvard Medical School, Boston, Massachusetts. Electronic address:

Background: Body mass index (BMI) does not reliably predict Surgical site infections (SSI). We hypothesize that abdominal wall thickness (AWT) would serve as a better predictor of SSI for patients undergoing emergency colon operations.

Methods: We retrospectively evaluated our Emergency Surgery Database (2007-2018). Read More

Direct 3D ultrasound fusion for transesophageal echocardiography.

Comput Biol Med 2021 May 21;134:104502. Epub 2021 May 21.

Division of Cardiology, Department of Medicine and Therapeutics, Prince of Wales Hospital and Laboratory of Cardiac Imaging and 3D Printing, Li Ka Shing Institute of Health Science, Faculty of Medicine, The Chinese University of Hong Kong, Hong Kong, China.

Background: Real-time three-dimensional transesophageal echocardiography (3D TEE) has been increasingly used in clinic for fast 3D analysis of cardiac anatomy and function. However, 3D TEE still suffers from the limited field of view (FoV). It is challenging to adopt conventional multi-view fusion methods to 3D TEE images because feature-based registration methods tend to fail in the ultrasound scenario, and conventional intensity-based methods have poor convergence properties and require an iterative coarse-to-fine strategy.

What Is the Risk of Intraoperative Cerebral Oxygen Desaturation in Patients Undergoing Shoulder Surgery in the Beach Chair Position?

Clin Orthop Relat Res 2021 06 15. Epub 2021 Jun 15.

Department of Anesthesiology, Faculty of Medicine, Chulalongkorn University, Bangkok, Thailand.

Background: Previous studies have shown that intraoperative cerebral desaturation in patients undergoing shoulder surgery in the beach chair position varies widely, from 0% to 80%. To our knowledge, the risk of intraoperative cerebral desaturation is not known after all identified intraoperative modifiable physiologic parameters that influence cerebral blood flow have been controlled for.

Questions/purposes: (1) What is the risk of intraoperative cerebral desaturation during shoulder surgery with the patient in the beach chair position when patients received combined general anesthesia and an interscalene block, and what other factors associated with intraoperative cerebral desaturation can be identified? (2) Is intraoperative cerebral desaturation associated with 24-hour cognitive decline? (3) What factors are associated with intraoperative hypotension?

Methods: Between April and December 2020, 51 patients underwent elective shoulder surgery in the beach chair position at one center. Read More

Mapping and Crosswalk of the Oxford Hip Score and Different Versions of the Hip Disability and Osteoarthritis Outcome Score.

Clin Orthop Relat Res 2021 Jul;479(7):1534-1544

Orthopedics Department, Lille University Hospital Lille, Hôpital Salengro, Lille, France.

Background: Patient-reported outcome measures such as the Oxford-12 Hip Score and Hip Disability and Osteoarthritis Outcome Score (HOOS) are used in daily orthopaedic practice to evaluate patients. Because different studies use different scores, it would be important to build conversion tables between scores (crosswalk) to compare the results of one study with those of another study. Various mapping methods can be used to develop crosswalk tables that convert Oxford-12 scores to the HOOS (and its derivatives, including the HOOS physical function short form, HOOS joint replacement, and HOOS-12) and vice versa.

Is chest radiography a valid alternative to computed tomography in evaluation of pectus excavatum?

Minerva Pediatr (Torino) 2021 Jun 15. Epub 2021 Jun 15.

Department of Pediatric Surgery, Bambino Gesù Pediatric Hospital - IRCCS, Rome, Italy.

Background: Current pectus excavatum management includes a Computed Tomography scan to evaluate the Correction Index, whose superiority to the Haller Index in terms of specificity and sensibility is still under debate. Furthermore, several studies report interchangeability between the Haller Index as measured by Computed Tomography and as measured by X-radiograph; however it is not clear whether this correlation also exists for the Correction Index. The aim of our study was to evaluate the correlation between measurements of the Haller Index and the Correction Index obtained by Computed Tomography and by X-radiograph. Read More

Diaphragma sellae sinking can predict the onset of hyponatremia after transsphenoidal surgery for pituitary adenomas.

J Endocrinol Invest 2021 Jun 14. Epub 2021 Jun 14.

Fuzong Clinical Medical College of Fujian Medical University, Fuzhou, 350025, China.

Purpose: Sinking of the diaphragma sellae (DS) may stretch the pituitary stalk, which in turn impairs neurohypophyseal function; thus, it may play a role in the development of postoperative hyponatremia. We aimed to assess the factors influencing the development of hyponatremia after transsphenoidal surgery (TSS) for pituitary adenomas and analyze the effect of DS sinking on hyponatremia.

Methods: After applying the inclusion and exclusion criteria, we retrospectively analyzed the clinical data of patients with pituitary adenoma who underwent TSS. Read More

Monoclonal B lymphocytosis in a kidney transplant recipient.

BMJ Case Rep 2021 Jun 14;14(6). Epub 2021 Jun 14.

Department of Surgical, Medical, Dental and Morphological Sciences, Università degli Studi di Modena e Reggio Emilia, Modena, Emilia-Romagna, Italy.

Monoclonal B lymphocytosis (MBL) is a lymphoproliferative condition characterised by expansion of a B-cell clone in peripheral blood, with an often indolent clinical course. The presence of a B clonal population alone is several hundred times more common in the general population than chronic lymphocytic leukaemia and other non-Hodgkin's lymphoma subtypes, it usually does not represent a malignant condition and it requires follow-up only, without specific treatment. There are few studies describing MBL in solid organ transplant recipients, thus, the concern is raised when enrolling MBL affected subjects in waiting lists. Read More
