The purpose was to determine the accuracy of the techniques of Lopes et al. and Michels et al., compared to ultrasound, to locate the center of the calcaneal footprint of the CFL in healthy volunteers.

Evaluation of plasma cortisol during fasting test in patients with endogenous hyperinsulinemic hypoglycemia. Fifteen years experience.

Background: Endogenous hyperinsulinemic hypoglycemia (EHH) is a rare clinical condition. The aim of this study was to evaluate baseline plasma cortisol concentration and its concentration during hypoglycemic crisis in fasting tests (FT) performed in our center. Secondarily, the aim was to establish the relationship between baseline cortisol and the time of evolution of EHH.

Endoscopic assisted flexor digitorum longus transfer in flexible flatfoot.

Background: Posterior tibial tendon insufficiency is the commonest cause of adult flexible flatfoot. Transfer of the flexor digitorum longus (FDL) has been described a therapeutic arsenal in flexible flat feet and posterior tibial tendon disorders. It is often combined with bony procedure (open or percutaneous calcaneal osteotomy).

Pembrolizumab-Induced Adrenal Insufficiency Presenting Eight Months After Cessation of Treatment.

Pembrolizumab is a monoclonal antibody that functions as an immune checkpoint inhibitor. It is an FDA-approved immunotherapy used to treat various malignancies. With its wide use in cancer therapy, there are many known side effects.

A Delayed Presentation of Bilateral Adrenal Hemorrhage Secondary to COVID-19.

Background/objective: Bilateral adrenal hemorrhage is a rare cause of adrenal insufficiency. Cases have been reported of acute adrenal crisis with bilateral adrenal hemorrhage during acute coronavirus disease of 2019 (COVID-19). Our objective was to report a delayed presentation of acute adrenal crisis with bilateral adrenal hemorrhage 2 months after COVID-19.

Re-ruptures and early outcomes after surgical repair of acute Achilles tendon ruptures: prospective, comparative multicenter study.

Purpose: The primary objective of this study was to compare the re-rupture rate, clinical results, and functional outcomes six months after the surgical repair of an acute Achilles tendon rupture between three different techniques (open repair, percutaneous repair with the Tenolig®, and minimally invasive repair).

Methods: A prospective, comparative, multicenter, non-randomized study was performed and included 111 patients who had an acute ruptured Achilles tendon: 74 underwent an open repair, 22 underwent a percutaneous repair using the Tenolig® and 15 had a minimally invasive repair. At six months follow-up we analyzed the number of re-ruptures, phlebitis, infections, complex regional pain syndrome, clinical outcomes (muscle atrophy, ankle dorsal flexion), functional scores (ATRS, VISA-A, EFAS, SF-12), and return to running.

First Outpatient Clinical Trial of a Full Closed-Loop Artificial Pancreas System in South America.

Background: The first two studies of an artificial pancreas (AP) system carried out in Latin America took place in 2016 (phase 1) and 2017 (phase 2). They evaluated a hybrid algorithm from the University of Virginia (UVA) and the automatic regulation of glucose (ARG) algorithm in an inpatient setting using an AP platform developed by the UVA. The ARG algorithm does not require carbohydrate (CHO) counting and does not deliver meal priming insulin boluses.

Subtalar arthrodesis using a single compression screw: a comparison of results between anterograde and retrograde screwing.

Introduction: The primary objective of this study was to compare the radiological and clinical results of anterograde and retrograde screwing in subtalar arthrodesis using a single compression screw. The secondary objective was to evaluate the subjective results and consolidation of this procedure. The hypotheses were that isolated screw fixation was sufficient to achieve good consolidation and that there was no difference between the two techniques with a similar rate of bone fusion.

Anatomical subject validation of an instrumented hammer using machine learning for the classification of osteotomy fracture in rhinoplasty.

Osteotomies during rhinoplasty are usually based on the surgeon's proprioception to determine the number and the strength of the impacts. The aim of this study is to determine whether a hammer instrumented with a force sensor can be used to classify fractures and to determine the location of the osteotome tip. Two lateral osteotomies were realized in nine anatomical subjects using an instrumented hammer recording the evolution of the impact force.

Using an impact hammer to perform biomechanical measurements during osteotomies: Study of an animal model.

Osteotomies are common surgical procedures used for instance in rhinoplasty and usually performed using an osteotome impacted by a mallet. Visual control being difficult, osteotomies are often based on the surgeon proprioception to determine the number and energy of each impact. The aim of this study is to determine whether a hammer instrumented with a piezoelectric force sensor can be used to (i) follow the displacement of the osteotome and (ii) determine when the tip of the osteotome arrives in frontal bone, which corresponds to the end of the osteotomy pathway.

Are Schatzker and AO classifications accurate enough to classify tibial plateau fractures in alpine skiers?

Purpose: The aims of this study were (1) to collect prospectively all tibial plateau fractures admitted to our department, over two ski seasons, and to classify them according to the Schatzker and AO classifications; (2) to assess if these classifications are accurate enough to include all types of fractures; and (3) to compare theses fractures with the series found in the literature, which included very few or no skiing accidents.

Methods: During the 2016-2017 and 2017-2018 ski seasons, we prospectively included 116 tibial plateau fractures caused by downhill skiing accidents. All patients underwent standard X-rays and 2D and 3D CT scans.

Rheumatoid Forefoot Reconstruction in Nonrheumatic Patients: Lesser Metatarsal Head Resection versus Osteotomy.

In the literature, first metatarsophalangeal joint arthrodesis with lesser metatarsal head resection seems to be a reliable procedure in rheumatoid foot deformity. Maybe this procedure could be proposed in nonrheumatoid severe forefoot deformity (hallux valgus angle >40° and lesser metatarsophalangeal dislocation). The aim of this study was to compare radiological and clinical outcomes between lesser metatarsal head resection and lesser metatarsal head osteotomy in nonrheumatoid patients.

Assessment of Evertor Strength Following Inferior Extensor Retinaculum Flap Ligamentoplasty in Patients With Chronic Lateral Ankle Instability.

The primary aim of our study was to evaluate the strength of ankle evertor muscles in patients who have undergone a lateral ankle ligamentoplasty (which combined tensioning of the primary ligament group and reinforcing it with a pediculated extensor retinaculum flap), using 2 measurement systems (isokinetic and the functional weightbearing test [MyoLux). Our hypothesis was the strength of evertor muscles on the treated side was comparable to that of the contralateral healthy side. This prospective study included 23 patients who had chronic ankle instability and underwent an inferior extensor retinaculum flap ligamentoplasty.

Outcomes of acetabular fractures in the elderly: a five year retrospective study of twenty seven patients with primary total hip replacement.

Purposes: Open reduction and internal fixation (ORIF) in osteoporotic acetabular fractures is quite difficult with high risk of implant failure. Total hip arthroplasty (THA) may be an effective option for treating acetabular fractures in appropriately selected patients, with immediate full weightbearing. The aim of the study was to evaluate the functional outcomes of primary THA for acetabular fractures in elderly patients.

Artificial Pancreas: Clinical Study in Latin America Without Premeal Insulin Boluses.

Background: Emerging therapies such as closed-loop (CL) glucose control, also known as artificial pancreas (AP) systems, have shown significant improvement in type 1 diabetes mellitus (T1DM) management. However, demanding patient intervention is still required, particularly at meal times. To reduce treatment burden, the automatic regulation of glucose (ARG) algorithm mitigates postprandial glucose excursions without feedforward insulin boluses.

Sleep Disorders and Cardio-Renal Disease: Implications for Minority Populations.

Obesity is a major public health problem that is reaching pandemic proportion. Currently two thirds of the American population is either overweight or obese and worldwide, 39% of the population is overweight and 13% are considered obese [1,2]. This rapid rise in obesity is associated with increased in diabetes mellitus type 2 (DM2), hypertension (HTN), chronic kidney disease (CKD) and cardiovascular diseases (CVD), the major killer of adults in the USA.

Transient lingual papillitis: case reports.

The term transient lingual papillitis (TLP) was suggested by Whitaker et al. in 1996. It describes a condition of the tongue that is relatively common but with few documented cases.

Labial bone concavity.

Labial bone concavities are entities that can be mistaken radiographically for disease. Clinicians should be aware of them in order to make a proper diagnosis. In the area of the concavity, the bone is thinned and appears more radiolucent than the adjacent bone.

Gingival cysts in the adult.

Background: Gingival cysts in the adult are unusual cysts of odontogenic origin with less than 100 reported, including this series. Even rarer are cases of multiple gingival cysts. This paper reports the second largest retrospective study of biopsy cases of adult gingival cysts with a spectrum of their features and another case of multiple gingival cysts.

Gingival fibrous nodule.

Five patients with small, exophytic, asymptomatic fibrous nodules, single or multiple, of the mandibular mucogingival zone of the anterior labial gingiva are presented. Such nodules are benign and resemble small fibromas. The clinical and histologic appearance distinguishes them from entities such as retrocuspid papilla, reticular mandibular gingival ridges, oral hamartomas associated with Cowden's syndrome, tuberous sclerosis oral lesions, and oral nodules secondary to epidermolysis bullosa.
