West Pharmaceutical Services out of Exton, Pennsylvania won FDA clearance for its innovative NovaGuard SA safety system that prevents needle-sticks by providing a mechanism that can be activated to cover the needle immediately after injection. It has an indicator if the shield has been damaged and will become non-functional if that happens to make sure it’s disposed of properly.

The Eko, developed by Eko Devices out of Berkeley, California, hooks up to the stem of just about any stethoscope’s chestpiece and is paired with a matching app that powers a lot of its features. It can then record exams for later review, display the visualization of the sounds, and control how the sound comes across to the listener. The app can upload recordings to an EHR or email them to another physician for review.

The company expects FDA clearance by the end of the year and is planning to start clinical trials in the SF Bay Area to evaluate the value it can offer both clinically and economically.

A 48-year-old woman who had worn a hearing aid in her left ear for many years presented to the emergency department with severe otalgia of 1 day's duration. Bloody otorrhea in the left ear was noted after the hearing aid was removed. Physical examination showed a fruit-fly larva moving in the left external auditory canal (see video). The skin over the floor of the auditory canal, close to the eardrum, was eroded. The larva was removed uneventfully, and the patient received topical antibiotic treatment with ofloxacin.

Severe bleeding is a primary cause of death for soldiers wounded on the battlefield. Deep shrapnel and gunshot wounds can be notoriously difficult to control, particularly in soft tissue places such as the neck, shoulder, and groin. Now undergrad students at Johns Hopkins University have developed a prototype device to help address such trauma in a speedy fashion.

The new device is a large plastic syringe with two compartments, similar to epoxy injectors, holding a polyol and a diisocyanat, chemicals that produce polyurethane foam when mixed. The foam hardens shortly after injection and delivers pressure to the wound from within. The hope is that the foam will help soldiers from bleeding out while they’re on the way to a medical facility where a surgeon can address the wound directly.

The FDA has just issued approval for the Xstat to be used by the U.S. military, but only on areas of the body where a tourniquet would be inappropriate. It’s indicated for up to four hours of use, which should allow ample time to get a wounded soldier to a battlefield surgeon.

Battlefield injuries can be the most difficult emergencies to deal with, requiring both immediate treatment and properly trained clinical professionals to perform under intense pressure. Severe hemorrhaging is usually the greatest threat to an injured soldier’s life and tourniquets have been used in countless situations to save life, if not limb. Severe bleeding in places where a traditional tourniquet cannot be applied requires constant focused pressure delivered to the wound site.

Traditional tourniquets, because of their ease of use and immediate benefit, have been life savers for countless soldiers injured in battle. Yet, there are large areas of the body where a tourniquet is simply not useful, like the neck, groin, and abdomen.

Catastrophic Bleeding: In all military situations a tourniquet is proposed as the initial treatment. In a civilian setting this is not openly or universally directed but where appropriate this could be applied in the first instance.

There is no doubt that tourniquets provide an effective means to stop 'catastrophic haemorrhage' - serious bleeding wounds to the extent that death is imminent due to blood loss. tourniquets are commonly used by the military worldwide, by Emergency Services in the US and - to a lesser extent - in the UK.

A 19-year-old man presented to the emergency department with a 2-day history of shortness of breath and pain on the right side of the chest. He reported no history of trauma, smoking, or respiratory illness, and there was no family history of emphysema or connective-tissue disease. On physical examination, his respiratory rate was 40 breaths per minute; oxygen saturation, 97% while he was breathing ambient air; heart rate, 130 beats per minute; and blood pressure, 140/80 mm Hg. A chest examination revealed decreased breath sounds on the right side accompanied by resonance on percussion

chest film showed tension pneumothorax, with marked leftward deviation of the trachea, heart, and mediastinum and herniation of air across the midline (Panel A, arrows). A chest tube was inserted, and symptoms resolved immediately. A subsequent chest film obtained 6 hours later showed partial expansion of the collapsed lung (Panel B, arrowheads); the chest tube can also be seen (arrows). The lung fully expanded after a few days. Computed tomography of the thorax revealed no emphysematous changes. The patient was discharged without a clear determination of the cause of his condition

A 92-year-old woman was admitted to the hospital with a severe left-sided ischemic stroke causing altered mental status (i.e., a score of 9 on the Glasgow Coma Scale, on which scores range from 3 to 15, with higher scores indicating increased consciousness), weakness on the right side, and dysphagia. An initial attempt to insert a small-caliber nasogastric tube for feeding was unsuccessful, with coiling of the tube in the mouth. A subsequent attempt with a stiff stylet resulted in easy insertion, without cough or respiratory distress

While awaiting radiography to confirm positioning of the tube, the patient had shortness of breath and was found to have decreased air movement in the right lung. Chest radiography revealed the tip of the nasogastric tube lying in the pleural space in the presence of a large pneumothorax on the right side (arrow). The nasogastric tube was removed immediately, but the patient died before further intervention
اعظم ۵۹۴۷۳

The nasogastric tube was removed immediately, but the patient died before further intervention. Though nasogastric tubes are generally considered safe, there is a risk of substantial pulmonary complications from blind insertion of small-caliber nasogastric tubes with a stiff stylet, particularly in patients with a reduced Glasgow Coma Scale score

A 32-year-old man presented with vision loss in the left eye. one week earlier, while under local anesthesia, he had had an autologous fat injection into his forehead for correction of glabellar frown lines. The patient reported that while he was receiving the injection, he felt a sudden, severe periocular pain and had complete vision loss in his left eye
اعظم ۵۹۴۷۳

اعظم ۵۹۴۷۳

On physical examination, the patient's level of consciousness was normal, without aphasia. Neurologic examination was normal except that he had no light perception in the left eye. The left pupil was dilated. In the left eye, no direct pupillary light reflex was observed and the indirect pupillary light reflex was slow. Retinal examination of the affected eye showed an edematous optic disk and widespread retinal whitening, with interruption of several arterioles (Panel A)
اعظم ۵۹۴۷۳

Follow-up photography and fluorescein angiography confirmed multiple retinal hemorrhages, occlusions of several retinal arterioles with visible fat emboli (Panel B, arrows), and complete lack of perfusion of the tissue bed in hypofluorescent areas (Panel C). No abnormality was seen on magnetic resonance angiography of the brain. At the 2-month follow-up visit, the patient's vision had not improve

A 65-year-old woman with chronic atrial fibrillation was admitted for an elective exchange of an implanted defibrillator for idiopathic dilated cardiomyopathy. To facilitate this procedure, warfarin was withheld for 5 days. Before the procedure was performed, acute-onset right hemiparesis and expressive dysphasia developed. Urgent noncontrast computed tomography (CT) of the brain and CT angiography of the intracranial and extracranial arterial circulation confirmed an acute occlusion of the M2 segment of the middle cerebral artery, which was consistent with the presence of an embolus (Panel A, arrow).
اعظم ۵۹۴۷۳

Ninety-five minutes after the onset of neurologic deficits, the patient was given a bolus dose and 1-hour infusion of tissue plasminogen activator. Repeat CT angiography, performed 25 hours after thrombolysis, showed reperfusion of the middle cerebral artery and cortical branches in the sylvian fissure on the left side (Panel B), which correlated with resolution of the neurologic deficits. Early administration of a thrombolytic agent is essential for optimal neurologic recovery. The patient has had no further neurologic symptoms, with no measurable deficit.

Scientists in Sweden, from Chalmers University of Technology, Sahlgrenska Academy, and Sahlgrenska University Hospital, have created a new helmet, called Strokefinder, for the rapid identification of hemorrhagic stroke. The idea is that such helmets would be equipped into ambulances and aide in the diagnosis of patients on their way to the hospital to shave precious minutes before treatment can begin. The helmet detects the presence of pooled blood in the brain by sending and receiving biologically-safe microwave pulses (no, there’s no “Popcorn” setting on the helmet). If a bleed is present, the helmet will pick up the signal as a unique scatter pattern

Scientists Cook Up Microwave Helmet for Early Stroke Identification
اعظم ۵۹۴۷۳

The system was made to teach itself which microwave scatter patterns point to hemorrhagic stroke via a computer learning algorithm and has shown considerable results, given the small sample size (roughly 20 patients) studied: “At 99.9% sensitivity to detect ICH [intracerebral hemorrhage], the proportion of IS [ischemic stroke] patients safely differentiated was approximately 30%, whereas at 90% ICH sensitivity 65% of IS patients could be differentiated.” It’s expected that the predictive power of the algorithm will improve as larger clinical trials ramp up to provide more samples for the system to learn from.
