Rivka Bendrihem, Christian Vacher, Audrey Fohlen, Jean-Pierre Pelage
PURPOSE: In Le Fort 1 osteotomy when a maxillary impaction is necessary, surgeons have to face different anatomical problems. (1) To determine the best bone resection route, they have to consider the situation of dental roots, infraorbital foramen and maxillary artery. (2) In case of Le Fort 1 osteotomy combined with a mandibular sagittal split osteotomy, the palate has to be replaced in horizontal position although there is no anatomical landmark. (3) In case of Gummy smiles, it can be due to either long face or short upper lip...

We present a case of Weil's disease complicated by a Jarisch-Herxheimer reaction (JHR) after initiation of antibiotics while in the emergency department requiring invasive monitoring and vasopressor support. The case is followed by a brief review of the JHR which is rarely observed with treatment of leptospirosis. A healthy 28-year-old female who recently returned from the Caribbean presented to the emergency department with flu-like symptoms. The patient appeared jaundiced with conjunctival suffusion and was ultimately treated with the appropriate antibiotics for leptospirosis in the ED...

BACKGROUND: Surgical access to Meckel's Cave (MC) is challenging due to its deep location and surrounding important neurovascular structures. Currently existing endoscopic endonasal (EE) approaches require dissecting near the internal carotid artery (ICA) or require transposition of the pterygopalatine neurovascular bundle. OBJECTIVE: To describe a novel approach to access the anterolateral aspect of the MC using a minimally invasive EE route. METHODS: The EE transmaxillary transinferior orbital fissure approach was simulated in 10 specimens...

Radiofrequency (RF) ablation is the first-line management of cavo-tricuspid isthmus dependent atrial flutter. It has been performed with 95% success rate. Adverse events are very rare. We report the first case of acute severe mitral regurgitation (MR) and complete heart block developed after successful atrial flutter ablation. A 62-year-old female with mild MR presented with palpitations. Surface electrocardiogram was suggestive of isthmus dependent atrial flutter. A duodecapolar mapping catheter showed an atrial flutter with cycle length of 280 ms...

Accurate knowledge of surface anatomy is fundamental to safe clinical practice. A paucity of evidence in the literature regarding thoracic surface anatomy in children was identified. The associations between surface landmarks and internal structures were meticulously analyzed by reviewing high quality computed tomography (CT) images of 77 children aged from four days to 12 years. The results confirmed that the sternal angle is an accurate surface landmark for the azygos-superior vena cava junction in a plane through to the level of upper T4 from birth to age four, and to lower T4 in older children...

Vera Goldberg, Boris Martinez, Katia Cnop, Peter Rohloff
We present a female infant with a right-sided facial and neck haemangioma, from a remote, resource-poor community in rural Guatemala. She received first-line treatment, propranolol, with marked reduction in tumour size and erythema. Treatment was stopped after 35 weeks due to recurrent diarrhoea and sustained weight loss. Propranolol can be used to safely treat infants with haemangiomas in remote, rural communities if there is adequate follow-up, education and communication. Periocular haemangiomas should be treated promptly to avoid visual impairment...

Ovarian torsion is a surgical emergency characterized by a partial or complete rotation of the ovarian vascular pedicle, causing obstruction to venous outflow followed by arterial inflow. Clinically, ovarian torsion frequently mimics other causes of acute pelvic pain such as appendicitis, diverticulitis, renal colic etc. Ultrasonography (US) is the first line imaging modality of choice for evaluation of ovarian torsion. MRI is useful as a problem solving tool in patients with equivocal or non diagnostic US studies...

PURPOSE OF REVIEW: Norepinephrine is the first-line agent recommended during resuscitation of septic shock to correct hypotension because of depressed vascular tone. Important clinical issues are the best timing to start norepinephrine, the optimal blood pressure target, and the best therapeutic options to face refractory hypotension of when high doses of norepinephrine are required to reach the target. RECENT FINDINGS: Recent literature has reported benefits of early administration of norepinephrine because of the following reasons: profound and durable hypotension is an independent factor of increased mortality, early administration of norepinephrine increases cardiac output, improves microcirculation and avoid fluid overload...

REVIEW

The adult pumping heart is formed by distinct tissue layers. From inside to outside, the heart is composed by an internal endothelial layer, dubbed the endocardium, a thick myocardial component which supports the pumping capacity of the heart and exteriorly covered by a thin mesothelial layer named the epicardium. Cardiac insults such as coronary artery obstruction lead to ischemia and thus to an irreversible damage of the myocardial layer, provoking in many cases heart failure and death. Thus, searching for new pathways to regenerate the myocardium is an urgent biomedical need...

Helicobacter pylori (H. pylori) infection is one of the major causes of bleeding peptic ulcer disease, which is associated with serious complications; therefore, the eradication of H. pylori is essential to prevent these devastating complications. Post-treatment follow-up is crucial to guarantee the eradication of the organism and may be conducted via the urea breath test, the stool antigen test, or a gastric biopsy. Acute massive upper gastrointestinal (UGI) bleeding is one of the most common complications of peptic ulcer disease...

A 44-year-old woman was admitted to our hospital with dengue fever. She developed a haematoma in the right arm at the site of a previous arterial line insertion. Due to coexisting thrombocytopenia, the bleeding was severe enough to cause compartment syndrome. An emergency fasciotomy was performed and her limb salvaged. The case illustrates one important potential complication of this common infectious disease.
