OBJECTIVES: Lingual tonsilloliths are not as well-known to radiologists than palatine tonsilloliths, although they might be common in clinical practice. The aim of this investigation was to clarify the prevalence and imaging characteristics of lingual tonsilloliths using panoramic radiographs and computed tomography (CT) images. SUBJECTS AND METHODS: This study included 2244 patients without pathology at the base of tongue who underwent panoramic radiography and CT of the maxillofacial region...

Rocky Mountain spotted fever (RMSF) is an emerging public health concern near the US-Mexico border, where it has resulted in thousands of cases and hundreds of deaths in the past decade. We identified 4 patients who had acquired RMSF in northern Mexico and subsequently died at US healthcare facilities. Two patients sought care in Mexico before being admitted to US-based hospitals. All patients initially had several nonspecific signs and symptoms, including fever, headache, nausea, vomiting, or myalgia, but deteriorated rapidly without receipt of a tetracycline-class antimicrobial drug...

We present the case of a 31-year-old female with a past medical history of B-cell leukemia, on maintenance chemotherapy administered via centrally placed implantable catheter port, who presented to the emergency room with fever, chills, and generalized body pain of one day's duration. After initial workup, the patient was admitted to the intensive care unit and managed for severe sepsis. The patient was found to have a new-onset 3/6 holosystolic murmur at the left lower sternal border. Furthermore, she developed an episode of supraventricular tachycardia that responded to adenosine...

Prevention of aging is mainly obtained through appropriate health practices, modulated by the genetic causes of aging. Causes of facial structural aging include gravity, volume loss, contraction of the mimic muscles and obviously biological aging of tissues. Among the very numerous new surgical technique of facial rejuvenation, we could point out: for the frontal region, obviously we are focus on the endoscopic and non-endoscopic frontal lifts. But also, we should note the transcutaneous Brow Shaping which with a well defined, step by step technique is indeed a simple way to improve a possible difficult situation; concerning the mid-face lift, as the main risk is the secondary eyelid malposition, a high Smas or a temporo-malar lift can be performed...

BACKGROUND: A strict high legal age limit for alcohol purchases decreases adolescents' access to alcohol, but little is known about long-term health effects. The aim was to estimate the effect of increased alcohol availability during adolescence on alcohol-related morbidity and mortality. METHODS: A nationwide register-based study using data from a natural experiment setting. In two regions of Sweden, strong beer (4.5%-5.6% alcohol by volume) became temporarily available for purchase in grocery stores for individuals 16 years or older (instead of 21) in 1967/1968...

Rationale: Delivery of connexin 43 (Cx43) to the intercalated disc is a continuous and rapid process critical for intercellular coupling. By a pathway of targeted delivery involving microtubule highways, vesicles of Cx43 hemichannels are efficiently trafficked to adherens junctions at intercalated discs. It has also been identified that actin provides rest stops for Cx43 forward trafficking, and that Cx43 has a 20kDa internally translated small C-terminus isoform (GJA1-20k) which is required for full-length Cx43 trafficking, but by an unknown mechanism...

Deep brain stimulation (DBS) of the medial forebrain bundle (MFB) induces rapid improvement of depressive symptoms in patients suffering from treatment-refractory major depressive disorder. It has been hypothesized that activation of the dopamine (DA) system contributes to this effect. To investigate whether DBS in the MFB affects DA release in the striatum, we combined DBS with fast-scan cyclic voltammetry (FSCV) in freely moving rats. Animals were implanted with a stimulating electrode at the border of the MFB and the ventral tegmental area, and a FSCV microelectrode in the ventromedial striatum to monitor extracellular DA during the acute onset of DBS and subsequent continued stimulation...

PURPOSE: Detailed characterization of changes in vessel size is crucial for the diagnosis and management of a variety of vascular diseases. Because clinical measurement of vessel size is typically dependent on the radiologist's subjective interpretation of the vessel borders, it is often prone to high inter- and intra-user variability. Automatic methods of vessel sizing have been developed for two-dimensional images but a fully three-dimensional (3D) method suitable for vessel sizing from volumetric X-ray computed tomography (CT) or magnetic resonance imaging has heretofore not been demonstrated and validated robustly...

BACKGROUND: Cutaneous leishmaniasis (CL) generally presents with a single or several localised cutaneous ulcers without involvement of mucous membranes. Ulcerated lesions are susceptible to secondary contamination that may slow the healing process. OBJECTIVE: This study verified the influence of non-parasitic wound infection on wound closure (epithelialisation) and total healing. METHODS: Twenty-five patients with a confirmed diagnosis of CL and ulcerated lesions underwent biopsy of ulcer borders...

An important application of intravascular optical coherence tomography (IVOCT) for atherosclerotic tissue analysis is using it to estimate attenuation and backscatter coefficients. This work aims at exploring the potential of the attenuation coefficient, a proposed backscatter term, and image intensities in distinguishing different atherosclerotic tissue types with a robust implementation of depth-resolved (DR) approach. Therefore, the DR model is introduced to estimate the attenuation coefficient and further extended to estimate the backscatter-related term in IVOCT images, such that values can be estimated per pixel without predefining any delineation for the estimation...

Changes in the electrical properties and thermal stability of HfO2 grown on Al2O3-passivated InSb by atomic layer deposition (ALD) were investigated. The deposited HfO2 on InSb at a temperature of 200 °C was in an amorphous phase with low interfacial defect states. During post-deposition annealing (PDA) at 400 °C, In-Sb bonding was dissociated and diffusion through HfO2 occurred. The diffusion of indium atoms from the InSb substrate into the HfO2 increased during PDA at 400 °C. Most of the diffused atoms reacted with oxygen in the overall HfO2 layer, which degraded the capacitance equivalent thickness (CET)...

BACKGROUND: High grade gliomas (HGGs) are locally invasive brain tumours that carry a dismal prognosis. Although complete resection increases median survival, the difficulty in reliably demonstrating the tumour border intraoperatively is a norm. The Department of Neurosurgery, Hospital Sungai Buloh is the first public hospital in Malaysia to overcome this problem by adopting fluorescence-guided (FG) surgery using 5-aminolevulinic acid (5-ALA). METHODS: A total of 74 patients with histologically proven HGGs treated between January 2008 and December 2014, who fulfilled the inclusion criteria, were enrolled...

OBJECTIVE: Simultaneous tumour resection and cranial reconstruction can be a challenging task. Surgical navigation is an indispensible tool in making this single-step procedure possible. In this case report we describe a new technique for this procedure to ensure a precise resection and optimal fit of the implant in a patient with an intraosseous meningioma. METHODS: We generated a 3D model of the patients skull based on a CT-scan and created a digital 'resection line' object using 3D Studio Max 2016 software...

BACKGROUND: When intubating newborns, clinicians aim to position the endotracheal tube (ETT) tip in the midtrachea. The depth to which ETTs should be inserted is often estimated using the infant's weight. ETTs are frequently incorrectly positioned in newborns, most often inserted too far. Using the vocal cord guide (a mark at the distal end of the ETT) to guide insertion depth has been recommended. OBJECTIVE: To determine whether estimating ETT insertion depth using the vocal cord guide rather than weight results in more correctly positioned ETT tips...

INTRODUCTION: Squamous Cell Carcinoma (SCC) includes several subtypes and these can be classified according to their clinical behaviours from the least invasive to the most aggressive. Moreover, it is appropriate to analyse their clinicalpathological patterns 1. In light of its wide histopathological variability, we encountered a rare malignant cutaneous lesion: a SCC of a proliferating trichilemmal tumour (PTT) nature. CASE REPORT: We describe the clinical and pathologic findings of an 82-year-old woman, who developed a SCC with areas of trichilemmal differentiation...

Dear Editor, An 83-year-old woman developed yellow-brownish infiltrates, nodules, and tumors mimicking xanthomas, mostly involving the periorbital and chest area within three months (Figure 1). She had no abnormalities in serum cholesterol or triglycerides levels. A detailed laboratory analysis revealed the presence of mild monoclonal gammopathy with a presence of immunoglobulin G (IgG) kappa light chains; however, according to hematologist consultation, it did not require medical intervention. Imaging assessment and ultrasound examination did not show any specific involvement of internal organs...

Superior vena cava (SVC) aneurysms are rare mediastinal vascular lesions. We report a case of a 42-year-old female, who presented to the outpatient department with features suggestive of lower respiratory tract infection. Chest X-ray showed abnormal contour and widening of right border of mediastinum. Computed tomography (CT) thorax revealed fusiform aneurysmal ectasia of SVC measuring 4.5 × 5.5 × 8.9 cm without internal thrombosis or dissecting flap. Management options include observation with follow-up and in some cases anticoagulation and surgical excision may be considered...

REVIEW
Inga Osmers
Disasters and armed conflicts are often the unfortunate basis for aid projects run by Doctors Without Borders/Médecins Sans Frontières (MSF). The nature of war and disasters means that surgery is an integral part of this medical emergency aid. In these situations, resources are usually limited. As a result, surgical work in these contexts differs significantly from the daily routine of a surgeon working in a highly resourced hospital. The principles of surgery do not change but surgeons must adapt their tactical approach to the changed context otherwise there is a high risk of failing to improve the health of patients and potentially jeopardizing their prospects for recovery...
