PURPOSE OF REVIEW: Headaches due to airplane travel are rare but documented in the literature. We aim to provide a review of diagnostic criteria and treatment for this condition. RECENT FINDINGS: Several cases of this syndrome have been reported since it was first described in 2004. Airplane headache is classified as unilateral, stabbing, orbito-frontal pain, lasting under 30 min, and occurs during ascent or descent of a plane. Patients with this condition can develop anxiety and fear of flying given the intensity and severity of the pain...

INTRODUCTION: Because Japan has high suicide rates and low violent crime rates, it is likely that most abdominal stab wounds (ASWs) in Japan are self-inflicted. Although physical examination is one of the most important factors in surgical decision making, such evaluations can be difficult in patients with self-inflicted ASWs due to patient agitation and uncooperative behavior. Therefore, the self-inflicted nature of an injury may strongly affect clinical practice, particularly in Japan, but its influence remains uncertain...

Animal horns play an important role during intraspecific combat. This work investigates the microstructure and mechanical properties of horns from four representative ruminant species: the bighorn sheep ( Ovis canadensis ), domestic sheep ( Ovis aries ), mountain goat ( Oreamnos americanus ) and pronghorn ( Antilocapra americana ), aiming to understand the relation between evolved microstructures and mechanical properties. Microstructural similarity is found where disc-shaped keratin cells attach edge-to-edge along the growth direction of the horn core (longitudinal direction) forming a lamella; multiple lamellae are layered face to face along the impact direction (radial direction, perpendicular to horn core growth direction), forming a wavy pattern surrounding a common feature, the tubules...

Aims Selective activation of nociceptive fibers is difficult using electrical stimulation as the activation threshold is higher than for non-nociceptive fibers. It remains unclear to what extent accommodation of non-nociceptive fibers during slowly rising electrical pulses can be utilized to reverse this activation order. The aim of this study was to evaluate the ability of different pulse forms to activate nociceptive fibers with minimal co-activation of non-nociceptive fibers by comparing subjective perception thresholds (PT)...

BACKGROUND: Penetrating stab wounds in children are relatively rare and no clear recommendations for the optimal evaluation have been devised. An acceptable traditional approach to the patient with an abdominal stab wound who does not require urgent surgery is selective nonoperative management and serial exams. The use of routine computed tomography remains an actively utilized investigation for these patients at many institutions. PURPOSE: We hypothesize that the approach to pediatric stab wound victims should be distinctly different than that of adult counterparts in order to minimize radiation exposure...

BACKGROUND: Intra-abdominal vascular injury (IAVI) is uncommon but continues to be associated with high mortality rates despite technological advances in the past decades. In light of these ongoing developments, we reviewed our contemporary experience with IAVI in an attempt to clarify and refine our management strategies and the outcome of these patients. METHODS: We retrospectively reviewed the charts of all patients admitted between January 2011 and December 2014 at a major trauma centre in South Africa who were found to have an IAVI during laparotomy for trauma...

BACKGROUND AND AIMS: Whiplash-Associated Disorders (WAD) are characterized by great variability in long-term symptoms. Patients with central neck and movement-induced stabbing pain participated in a randomized study comparing cervical fusion and multimodal rehabilitation. As reported in our previous paper, more patients treated by cervical fusion than by rehabilitation experienced pain relief. Although patient reported outcome measures are a core component of outcome evaluation, independent examiner has been recommended...

Impurity profiling has been used as a useful tool for analyzing nearly every drug class currently known on the illicit market. Impurities present within seized samples have the potential to determine source of origin, route of synthesis used, as well as provide a useful clue into the potential reaction mechanisms that are present for each synthetic procedure. Perhaps the most well studied of these impurity profiles exists for methamphetamine, including information to more than one route of synthesis. Within the present study, a complete synthesis of methamphetamine was performed, including a reductive amination of phenylpropanone (P2P) using methylamine hydrochloride and sodium triacetoxyborohydride (STAB) rather than the conventional aluminum mercury amalgam commonly found in the literature...

Introduction: Precision of movements responsible for maintaining balance deteriorates with age due to natural involutionary processes, thus prompting a research question whether the values of gender-related stability indicators might differ significantly among the study subjects over 60 years of age. Methods: The study group comprised 136 seniors (89 women, 47 men; aged 60-90 years). The CQ-Stab 2P 2-platform posturograph was used as the main research device, whereas the Mann-Whitney U -test was used to evaluate the gender-related differences in the average level of variables...

Varicocele is the dilatation of the scrotal portion of pampiniform plexus and the internal spermatic venous system. About 15% of men suffer from scrotal varicocele and 2% to 10% of them complain of pain. The probable mechanisms for pain include compression of the surrounding neural fibers by the dilated venous complex, elevated testicular temperature, increased venous pressure, hypoxia, oxidative stress, hormonal imbalances, and the reflux of toxic metabolites of adrenal or renal origin. Testicular pain associated with varicoceles is typically described as a dull, aching, or throbbing pain in the testicle, scrotum, or groin; rarely, it can be acute, sharp, or stabbing...

Bone daggers were once widespread in New Guinea. Their purpose was both symbolic and utilitarian; they functioned as objects of artistic expression with the primary function of stabbing and killing people at close quarters. Most daggers were shaped from the tibiotarsus of cassowaries, but daggers shaped from the femora of respected men carried greater social prestige. The greater cross-sectional curvature of human bone daggers indicates superior strength, but the material properties of cassowary bone are unknown...

A 19-year-old man with a stab injury to the lower back presented with no focal neurology or haemodynamic instability. He complained of a headache that was improved by lying flat and underwent imaging to look for damage to local structures. He was found to have air in his intraspinal space. Initially this case was managed conservatively; however, 2 weeks after discharge, he presented with cerebrospinal fluid leak from his wound. This was managed with neurosurgical intervention and watertight closure of fascia...
