High-flow nasal cannula oxygen therapy was effective for dysphagia associated with respiratory muscle paralysis due to cervical spinal cord injury: A case report.

RATIONALE: Respiratory muscle paralysis due to low cervical spinal cord injury (CSCI) can lead to dysphagia. Noninvasive positive airway pressure (PAP) therapy can effectively treat this type of dysphagia. High-flow nasal cannula (HFNC) oxygen therapy can generate a low level of positive airway pressure resembling PAP therapy, it may improve the dysphagia. PATIENT CONCERNS: The patient was an 87-year-old man without preexisting dysphagia. He suffered a CSCI due to a dislocated C5/6 fracture, without brain injury, and underwent emergency surgery. Postoperatively (day 2), he complained of dysphagia, and the intervention was initiated. DIAGNOSIS: Based on clinical findings, dysphagia in this case, may have arisen due to impaired coordination between breathing and swallowing, which typically occurs in patients with CSCI who have reduced forced vital capacity. INTERVENTIONS: HFNC oxygen therapy was started immediately after the surgery, and swallowing rehabilitation was started on Day 2. Indirect therapy (without food) and direct therapy (with food) were applied in stages. HFNC oxygen therapy appeared to be effective because swallowing function temporarily decreased when the HFNC oxygen therapy was changed to nasal canula oxygen therapy. OUTCOMES: Swallowing function of the patient improved and he did not develop aspiration pneumonia. LESSONS: HFNC oxygen therapy improved swallowing function in a patient with dysphagia associated with respiratory-muscle paralysis following a CSCI. It may have prolonged the apnea tolerance time during swallowing and may have improved the timing of swallowing. HFNC oxygen therapy can facilitate both indirect and direct early swallowing therapy to restore both swallowing and respiratory function.

Accidental falls related to clearing heavy snow on rooftops in a rural heavy snow area in Japan.

Aim: The purpose of this study is to describe our experience with patients who fell from rooftops while clearing snow. The falls occurred in rural areas that receive heavy snowfall and are undergoing depopulation and an increasing proportion of elderly residents. Methods: A retrospective observational chart review was carried out at the sole hospital providing emergency services in a rural heavy snow area in Japan. Results: A total of 70 patients were enrolled during four winter seasons between December 2009 and March 2013. Their mean age was 61 years, and 90% were male. The mean vertical height of falls was 4.1 m. A total of 174 injuries was observed, averaging 2.5 injuries per patient. Fractures accounted for 78% of all injuries, and main fractures included vertebra with lower extremities or rib fractures; 86% of patients sustained a maximum abbreviated injury scale score of 2-3. Conclusions: In a rural heavy snow area in Japan, the incidence of accidental falls related to clearing snow was high, and the victims were elderly. Fractures accounted for 78% of all injuries, and most patients suffered from moderate to serious injuries.

Generalized Status Epilepticus in a Patient with Acute-onset Type 1 Diabetes Mellitus Associated with Severe Kidney Dysfunction: A Case Report and Literature Review.

A 65-year-old Japanese man with advanced chronic kidney disease (CKD) developed acute-onset type 1 diabetes mellitus (T1D) that was associated with severe acute kidney injury and was manifested by generalized tonic-clonic status epilepticus. His seizures resolved without recurrence after correcting the diabetic ketoacidosis. Although hyperglycemia is an important cause of acute symptomatic seizure (ASS), patients with ketotic hyperglycemia develop ASS less frequently. In this T1D case with CKD, severe hyperglycemia in conjunction with other metabolic insults, such as uremia, hyponatremia, and hypocalcemia, probably provoked his seizure despite the severe ketonemia.
