[Quadricuspid Aortic Valve Diagnosed During Surgery in an Elderly Patient with Aortic Stenosis and Regurgitation:Report of a Case].

We report case details of a quadricuspid aortic valve that was diagnosed during surgery in an 82-yearold male with aortic valve stenosis and regurgitation. He had been treated for heart failure with atrial fibrillation, and aortic valve dysfunction. Sinus rhythm was restored after second catheter ablation for atrial fibrillation.

Simultaneous analysis of caffeine and paraxanthine provides potentially useful indexes in the treatment of acute caffeine intoxication.

Caffeine (CFF) is efficiently absorbed after ingestion, and approximately 80% of ingested CFF is metabolized to paraxanthine (PXT). Although PXT has approximately twice the adenosine receptor antagonist activity of CFF, there are few reports measuring the metabolite concentrations during CFF intoxication. Furthermore, no studies have examined the efficacy of hemodialysis (HD) on PXT or the indicators that contribute to treatment strategies for patients with acute CFF intoxication.

Successful Repair of a Ruptured Common Iliac Aneurysm with Associated Arteriovenous Fistula Using Aneurysm Wall.

Ruptured abdominal aortic aneurysms and common iliac artery aneurysms (CIAAs) are rarely associated with an arteriovenous fistula (AVF). In such cases, surgery is frequently extremely difficult and the prognosis is usually poor. We report a case of a ruptured CIAA with a common iliac AVF in a 58-year-old male patient who presented with symptoms of severe edema in his left lower extremity.

Mitral Valve Replacement for Bulky, Calcified Mitral Annulus: A Case Report.

Calcification of the mitral valve annulus is common in patients on dialysis. The growing number of individuals receiving dialysis has been accompanied by an increase in cases necessitating surgical intervention for mitral valve annulus calcification. In this report, we present a severe case characterized by bulky calcification of the mitral annulus, which was managed with mechanical mitral valve replacement.

Relapsing Polychondritis: A Case of Marked Improvement After Steroid Administration for Airway Obstruction.

Relapsing polychondritis is a rare disease that causes progressive and recurrent destruction of cartilage in the auricles, eyes, nose, and airways. A 90-year-old man was brought to the emergency department with fever, low SpO, and effortful breathing. Arterial blood gas analysis showed that PaCO levels had accumulated to 120 mmHg.

Laryngopharyngeal Mucosal Injury Due to Nasogastric Tube Insertion during Cardiopulmonary Resuscitation: A Retrospective Cohort Study.

Background: Patients under cardiopulmonary resuscitation (CPR) are at high risk of aspirating gastric contents. Nasogastric tube insertion (NGTI) after tracheal intubation is usually performed blindly. This sometimes causes laryngopharyngeal mucosal injury (LPMI), leading to severe bleeding.

Single-photon emission computed tomography (SPECT) predicted neurological prognosis in heat stroke: A case report.

Heat stroke may cause multi-organ dysfunction and death. Some patients with neurological abnormalities in the acute phase have neurological sequelae, particularly cerebellar ataxia, in the recovery phase. However, there is no method to predict the neurological prognosis, and the usefulness of imaging has not yet been established.

Stroke in Toddler After Minor Head Injury: An Emerging Diagnostic Challenge.

The diagnosis of ischemic stroke in toddlers in ED is a challenge due to non-specific neurological symptoms and difficulties in conducting a detailed neurological examination in toddlers. Magnetic Resonance Imaging (MRI) requires patient sedation and the cooperation of several medical personnel. A 33-month-old male presented with the immobility of the left upper extremity after a fall from a child chair.

Effect of PACAP on Heat Exposure.

Heat stroke is a life-threatening illness caused by exposure to high ambient temperatures and relative humidity. The incidence of heat stroke is expected to increase due to climate change. Although pituitary adenylate cyclase-activating polypeptide (PACAP) has been implicated in thermoregulation, the role of PACAP on heat stress remains unclear.

Benign noninfectious subcutaneous emphysema with minor injury: A case report.

Posttraumatic subcutaneous emphysema, which can be benign and noninfectious, is associated with necrotizing fasciitis. Rarely, extensive emphysema occurs after a minor traumatic injury. A 23-year-old man came to our hospital with extensive emphysema, ranging from the left hand to the axilla, after a minor injury.

Mild-intensity running exercise recovered motor function by improvement of ankle mobility after unilateral brain injury of mice using three-dimensional kinematic analysis techniques.

Motor dysfunction, such as gait impairment, is a major disability induced by traumatic brain injury or stroke. Treadmill running is often used as a physical exercise (Ex) clinically and experimentally for the recovery of patients. In animal experiments, although dynamic behavioral deficits can be evaluated using scoring systems, local and minor behaviors are difficult to determine.

Obstructive shock due to right ventricular compression by a massively expanded reconstructed gastric tube.

Obstructive shock is often associated with poor right ventricular (RV) output and requires rapid obstruction release. A 54-year-old man was brought to our emergency department, presenting with shock. He had previously undergone esophagectomy with gastric interposition through the retrosternal route, after which he could not eat solid foods.

A Case of Acute Non-ST Elevation Myocardial Infarction Later Revealed by Contrast-Enhanced Computed Tomography.

BACKGROUND Acute coronary syndrome is life-threatening. The diagnosis can be confirmed by electrocardiography (ECG) and serum cardiac biomarkers. Early diagnosis and treatment of non-ST segment elevation myocardial infarction (NSTEMI) is important because delayed treatment is associated with poor prognosis, especially in older adults.

Heatstroke-induced late-onset neurological deficits in mice caused by white matter demyelination, Purkinje cell degeneration, and synaptic impairment in the cerebellum.

Global warming increases heatstroke incidence. After heatstroke, patients exhibit neurological symptoms, suggesting cerebellar damage. However, the potential long-term adverse outcomes are poorly understood.

[Pedunculated and Mobile Right Atrial Thrombus Moderately after Mitral Valve Plasty and Tricuspid Valve Annuloplasty:Report of a Case].

An 81-year-old female underwent mitral valve plasty and tricuspid annuloplasty using an artificial annulus for mitral valve insufficiency and secondary tricuspid valve insufficiency at our hospital. Echocardiography 5 months later showed no abnormal finding. Eight months after the operation, however, a pedunculated and highly mobile mass in the right atrium was found, and the patient was admitted to our hospital.

[Surgical Repair of Right Atrium Perforation due to Brockenbrough Procedure:Report of a Case].

A 62-year-old woman had a history of catheter ablation three times in the past for atrial fibrillation underwent the fourth catheter ablation. Atrial septum was punctured by Brockenbrough procedure. Two 8 Fr sheaths were inserted into left atrium.

Guillain-Barré syndrome diagnosed as central cervical spinal cord injury after hyperextension injury.

The clinical features of Guillain-Barré syndrome (GBS) are progressive, fairly symmetric muscle weakness, and patients present a few days to a week after onset of symptoms. A 63-y-old man strongly hit his forehead, and next day felt paresthesia in both upper limbs, with difficulty in walking. Spinal cord injury (SCI) was suspected; the cervical cord was severely compressed at the C4 level.

[Constrictive Pericarditis Associated with Pericardial Hematoma:Report of a Case].

A 59-year-old man was admitted to our hospital due to keto-acidosis. Electric cardiogram showed history of myocardial infarction. Cardiac echogram showed severe left ventricular hypokinesis, thickened pericardium and pericardial effusion.
