The incidence of traumatic tympanic membrane rupture (TTMR) has increased over recent decades. The association of certain external injury causes and bone fracture patterns with TTMR is anecdotal. It has been suggested that a diagnosis of TTMR may be missed during the acute trauma admission. The authors sought to evaluate the incidence of TTMR according to external injury cause and evaluate the association of skull fracture patterns with TTMR using a national trauma database. A cross-sectional analysis of trauma encounters was conducted using the National Trauma Data Bank (NTDB) from 2008 to 2015...

INTRODUCTION AND IMPORTANCE: Chronic suppurative otitis media (CSOM) is a chronic inflammation of the middle ear associated with tympanic membrane rupture and purulent discharge for at least 6 weeks. Owing to the proper use and easy availability of antibiotics, these types of cases are rare in developed regions, but they are still occasionally seen in the developing world with poor hygiene and a lack of availability of antibiotics and immunizations. CASE PRESENTATION: Patient presented with complaints of headache, yellow-colored discharge from ear, fever and vomiting...

The frequency of injuries secondary to terrorist attack explosion is globally increasing. Like any other country, our country experienced multiple suicide bombings in recent years. Otologic injuries may be observed after these kinds of attacks. Considering otologic complaints are well known medical results of explosion attacks, routine otologic evaluation in the first examining hospital-even in case of no relevant complaint- is crucial for establishing causal relation in following forensic medicine evaluation...

Introduction : Advances in technology and technique have led to a significant improvement in the prognosis after cataract surgery. However, there are complications that can significantly affect this prognosis, such as posterior capsule rupture and corneal decompensation. For vitreous prolapse associated with posterior capsule rupture, classic or pars plana anterior vitrectomy is required. Aim : The aim of the study was to compare corneal endothelial cell destruction after cataract surgery associated with posterior capsule rupture and classical and pars plana anterior vitrectomy, respectively...

BACKGROUND: Bioprosthetic valve fracturing (BVF) results in low gradients following valve-in-valve transcatheter aortic valve replacement (ViV-TAVR). For the commonly used Edwards PERIMOUNT valve data from bench-testing are lacking to provide technical specifications for successful BVF during ViV-TAVR. METHODS: Using four Perimount 19- and 21-mm valves, in-vitro high-pressure balloon valvuloplasty with the True Dilatation Balloon Valvuloplasty Catheter and Atlas Gold PTA Dilatation Catheter was performed to analyze balloon-oversizing and pressure-thresholds to successfully achieve BVF...

Clinical Focus: An effort is made to delineate the underlying hemodynamic alteration in the usual care group registered with 5 patients @ 100% ihm; vs the sepsis protocol cohort with 11 patients @ 90.05% ihm with a median hospital stay of 5 days (Ref: Fig 3. Risk of ihm by subgroup for patients treated with the sepsis protocol vs usual care; p1239) NCT01663701, (PMID: 28973227). The goal is to explore whether there is any temporal link between neuropsychiatric indices and SSSP-2. Hypothesis: The AR clPr causing STD, with CCI, Tx with antibiotics (PMID: 31331661; NBK557820; PMID: 32491752), released toxins exacerbating the vortices formation in fluid bolus induced fluid volume expansion by Flow-Induced Vibration (FIV) (Oscillating flow) (VIV)...

Based on the theoretical inferences derived from industrial CFD modules, and hemodynamic data (SSSP-2), here we present a plausible physiological basis for the benefit of monitoring ISP for attenuation 100% ihm in the usual care cohort of SSSP-2 (PMID: 28973227). Hypothesis: ISP- and APG-dependent vortex shedding frequency(VSF) lead to stalling of blood flow augment rapid onset of mortality by rupturing of cerebral vessels. Rationale: Impact of form drag on streamline bodies. Geometry: Part I: RBC, Platelets, WBC: detailed geometry of RBC, Platelets, WBC, p47-56; Part II: Apr...

Round window rupture following barotrauma such as diving and air travel is well documented. However, we describe a case of round window rupture following a slap to the ear, which has not been described previously. A 12-year-old boy was slapped by his teacher in rural Nepal over his left ear and immediately noted hearing loss. There was no dizziness or tinnitus. He presented to our unit 21 days after the trauma and examination showed a perforation of the tympanic membrane in the anterior inferior quadrant with an otherwise normal ear examination and no nystagmus seen...

Electrical injuries in pediatric patients are uncommon but can be life-threatening and require efficient and effective identification and management. Injury severity is based on the characteristics of the electricity, the duration of contact with the electrical source, and the current's pathway through the body. This issue discusses the specific threats posed by high-voltage, low-voltage, and lightning injuries. The various presentations are described, including burns, arrhythmias, respiratory arrest, cardiac arrest, blunt trauma from falls or blast events, rhabdomyolysis, tympanic membrane rupture, and altered mental status, among others...

Cyclic oligonucleotide-based antiphage signaling systems (CBASS) are antiviral defense operons that protect bacteria from phage replication. Here, we discover a widespread class of CBASS transmembrane (TM) effector proteins that respond to antiviral nucleotide signals and limit phage propagation through direct membrane disruption. Crystal structures of the Yersinia TM effector Cap15 reveal a compact 8-stranded β-barrel scaffold that forms a cyclic dinucleotide receptor domain that oligomerizes upon activation...

The use of explosive devices in war and terrorism has increased exposure to concussive blasts among both military personnel and civilians, which can cause permanent hearing and balance deficits that adversely affect survivors' quality of life. Significant knowledge gaps on the underlying etiology of blast-induced hearing loss and balance disorders remain, especially with regard to the effect of blast exposure on the vestibular system, the impact of multiple blast exposures, and long-term recovery. To address this, we investigated the effects of blast exposure on the inner ear using a mouse model in conjunction with a high-fidelity blast simulator...

Chronic, severe otitis media was diagnosed in four Atlantic harbor seals ( Phoca vitulina concolor ), three of which were stranded animals undergoing rehabilitation. All seals presented with unilateral purulent aural discharge that would intermittently recur despite prolonged topical and systemic antimicrobial therapy. Aerobic culture from aural discharge isolated multidrug-resistant organisms in all seals, including Pseudomonas aeruginosa , Staphylococcus pseudintermedius , Klebsiella pneumoniae , and/or Enterococcus faecalis ...

Middle ear barotrauma (MEB) is a common complication of hyperbaric oxygen (HBO2) therapy. It has been reported in more than 40% of HBO2 treatments and can interrupt the sequence of HBO2. MEB may lead to pain, tympanic membrane rupture, and even hearing loss. The aim of this study was to determine if pretreatment with intranasal fluticasone and oxymetazoline affected the incidence of MEB. We conducted a retrospective chart review of subjects undergoing HBO2 at our institution between February 1, 2014, and May 31, 2019...
