Lung cancer can cause fatal central airway obstruction. Rapid airway clearance is necessary in some cases, but ventilator management may be insufficient to maintain oxygenation levels. ⋯ We herein report a case of central airway obstruction and severe acute respiratory failure due to small-cell lung cancer successfully treated with VV-ECMO, bronchoscopic airway intervention, and chemotherapy. VV-ECMO can be an effective option for the treatment of central airway obstruction with acute respiratory failure due to lung cancer.

Case Reports
An Elderly Woman with Complaints of Pain and Hearing Loss, Diagnosed with CMT1A with PMP22 Duplication.
Charcot-Marie-Tooth (CMT) disease is a heterogeneous hereditary motor and sensory neuropathy of the peripheral nervous system, with CMT1A in particular being the most common form. We encountered a 76-year-old woman with CMT1A who had a history of pain attacks and hearing loss from a young age, with motor symptoms manifesting late in life. Her pain and hearing loss may have been related to CMT. Our case also raises the possibility that neuropathic pain and hearing loss may precede the classic motor symptoms of CMT1A.

Objective Whether or not the initial dip in the glomerular filtration rate (GFR) after the initiation of sodium-glucose co-transporter 2 inhibitors (SGLT2is) is associated with renal tubular injury in patients with heart failure with a reduced ejection fraction (HFrEF) is unclear. We therefore investigated the relationship between changes in the estimated GFR (eGFR) and urine N-acetyl-β-D-glucosaminidase (uNAG) after the initiation of dapagliflozin in patients with HFrEF. Methods We prospectively investigated 89 patients with HFrEF who were newly started on dapagliflozin 10 mg/day. ⋯ The relative change in the systolic blood pressure, hematocrit, plasma volume, and N-terminal pro-brain natriuretic peptide (NT-proBNP) were correlated with the relative change in the eGFR. In a multiple linear regression analysis, the relative change in the eGFR at 2 weeks was significantly associated with NT-proBNP, and the relative change in the uNAG/Cre was significantly associated with the use of loop diuretics and the relative change in urine osmolality at 2 weeks. Conclusion A transient decrease in the eGFR after the initiation of dapagliflozin in patients with HFrEF was not generally associated with renal tubular injury and might have been the result of hemodynamic alteration.

A 78-year-old man was admitted to our hospital with obstructive shock caused by a large hiatal hernia that occupied the posterior mediastinum. Tension gastro-duodenothorax was detected in his stomach and duodenum, and we performed urgent endoscopy to relieve shock. Large hiatal hernia occasionally leads to cardiac failure. This is the first reported use of urgent endoscopy to treat a large hiatal hernia.

Encephalitis caused by antibodies targeting the leucine-rich glioma-inactivated 1 protein receptor, which belongs to the anti-voltage-gated potassium channel receptor complex, is characterized by hyponatremia, progressive cognitive impairment, seizures, and psychiatric disorders. The patient initially presented with faciobrachial dystonic seizures and subsequently developed encephalopathy. Brain magnetic resonance imaging revealed atypical unilateral hyperintense signals in the cerebral cortex and white matter. Intravenous corticosteroid pulse therapy effectively improved faciobrachial dystonic seizures and brain lesions.
