High-resolution ultrasound of the paratenon of the Achilles calcaneal tendon: anatomical study and description of the paratendinous injection technique.

Purpose: The aim of this study is to determine if ultrasound (US) allows a precise assessment of the paratenon (PT) of the Achilles calcaneal tendon (AT), and to anatomically describe the US-guided paratendinous injection technique.

Methods: This study was initially conducted on eight cadaveric specimens using high-resolution ultrasound (HRUS) to examine the PT appearance, thickness, and its relationships with the AT, plantaris tendon (PLT), Kager's fat pad (KFP), sural nerve (SN), and fascia cruris (FC). US-guided paratendinous injection of China ink was performed in all specimens, followed by anatomical dissection to assess injectate distribution.

Anatomical study of the medial calcaneal nerve using high-resolution ultrasound.

Objectives: To determine whether high-resolution ultrasound (US) can identify the course and relations of the medial calcaneal nerve (MCN).

Methods: This investigation was initially undertaken in eight cadaveric specimens and followed by a high-resolution US study in 20 healthy adult volunteers (40 nerves) by two musculoskeletal radiologists in consensus. The location and course of the MCN as well as its relationship to adjacent anatomical structures were evaluated.

Computed tomography-guided microwave ablation of perivascular liver metastases from colorectal cancer: a study of the ablation zone, feasibility, and safety.

Objectives: To compare the ablation margins and safety of microwave ablation (MWA) of perivascular versus non-perivascular liver metastases from colorectal cancer (CRC) and to determine the risk factors for local tumor progression (LTP) after perivascular MWA.

Methods: Between June 2017 and June 2019, 84 metastases were treated: 39 perivascular (<5 mm from a vessel >3 mm), and 46 non-perivascular. Perivascular metastases were treated with either conventional or optimized protocols (maximum power and/or several heating cycles after repositioning the needle regardless of the initial tumor dimensions).

Volcanic activity controls cholera outbreaks in the East African Rift.

We hypothesized that Cholera (Vibrio cholerae) that appeared along Lake Kivu in the African Rift in the seventies, might be controlled by volcano-tectonic activity, which, by increasing surface water and groundwater salinity and temperature, may partly rule the water characteristics of Lake Kivu and promote V. cholerae proliferation. Volcanic activity (assessed weekly by the SO2 flux of Nyiragongo volcano plume over the 2007-2012 period) is highly positively correlated with the water conductivity, salinity and temperature of the Kivu lake.

2-point ultrasonography to confirm correct position of the gastric tube in prehospital setting.

Unlabelled: X-ray remains the "gold standard" test to control the gastric tube (GT) position. The aim of this study is to estimate the diagnostic accuracy of a 2-point ultrasonography to confirm GT placement in the prehospital setting.

Method: The emergency physician performed an ultrasound examination during GT insertion.

Stay and play eFAST or scoop and run eFAST? That is the question!

Unlabelled: The concept that ultrasonography could be interesting in the prehospital setting and during the transfer of traumatized patients is not new. Paradoxically, there is a lack of description of routine use of ultrasonography in emergency ambulances. The aim of this study was to compare the feasibility and efficiency of an extended focused assessment sonography for trauma (eFAST) examination performed on-site, during the patient's transfer, or both.

Role of the French rescue teams in Diquini Hospital: Port-au-Prince, January 2010.

On January 12, 2010, Port-au-Prince, Haiti, was shattered by a violent earthquake that killed or injured thousands of its citizens. Local emergency services became overwhelmed and international assistance was required. French relief teams were deployed to assist local hospitals in caring for the victims.

Acute pancreatitis: a rare complication of acute hepatitis E.

Hepatitis E is an emerging imported disease in Europa but autochthonous cases are described for some years. Extra-hepatic associated manifestations are published. We report a case of acute necrotizing pancreatitis associated with imported acute viral E hepatitis (genotype 1a) in a 26 years old French man travelling and originated from Pakistan.
