A 33-year-old woman visited the emergency department presenting with fever and dyspnea. She was pregnant with gestational age of 31 weeks and 6 days. She had dysuria for 7 days, and fever and dyspnea for 1 day. The vital signs were as follows: blood pressure 110/70 mmHg, heart rate 118 beats/minute, respiratory rate 28/minute, body temperature 38.7℃, and oxygen saturation by pulse oximetry 84% during inhalation of 5 liters of oxygen by nasal prongs. Crackles were heard over both lung fields. There were no signs of uterine contractions. Chest X-ray and chest computed tomography scan showed multiple consolidations and air bronchograms in both lungs. According to urinalysis, there was pyuria and microscopic hematuria. She was diagnosed with community-acquired pneumonia and urinary tract infection (UTI) that progressed to severe sepsis and acute respiratory failure. We found extended-spectrum beta-lactamase producing Escherichia coli in the blood culture and methicillin-resistant Staphylococcus aureus in the sputum culture. The patient was transferred to the intensive care unit with administration of antibiotics and supplementation of high-flow oxygen. On hospital day 2, hypoxemia was aggravated. She underwent endotracheal intubation and mechanical ventilation. After 3 hours, fetal distress was suspected. Under 100% fraction of inspired oxygen, her oxygen partial pressure was 87 mmHg in the arterial blood. She developed acute kidney injury and thrombocytopenia. We diagnosed her with multi-organ failure due to severe sepsis. After an emergent cesarean section, pneumonia, UTI, and other organ failures gradually recovered. The patient and baby were discharged soon thereafter.

Waterproofing spray is commonly used to waterproof textile, tents, boots, etc. Chemical pneumonitis caused by inhalation of waterproofing spray has often been reported. Most waterproofing sprays contain a fluoropolymer in combination with hydrocarbons. However, chemical pneumonitis caused by waterproofing spray not containing fluoropolymer is uncommon. The authors are reporting a case of chemical pneumonitis caused by waterproofing spray, which contained hydrocarbon only. A 35-year-old man presented with dyspnea. The patient used a waterproofing spray on a tent for 30 minutes in a closed room. One hour and a half after spraying, the patient developed dyspnea, and his dyspnea had gotten worse. The patient's respiratory rate was fast, and the patient's arterial blood gas analysis showed hypoxemia. The chest X-ray and high resolution computed tomography showed bilateral ground-glass opacities and areas of consolidation in both lower lung fields. The patient was diagnosed with chemical pneumonitis caused by inhalation of waterproofing spray. Oxygen was given to the patient, and the patient was started on methylprednisolone intravenously. The patient's symptom improved after one day. After one week, most of symptoms of the patient improved and his chest X-ray showed improvement, so the patient was discharged. After discharge, oral prednisolone was prescribed instead of methylprednisolone, and was gradually tapered off. One month later, the patient's chest X-ray showed complete resolution.

In adults, most intussusceptions develop from a lesion, usually a benign or malignant neoplasm, and can occur at any site in the gastrointestinal tract. Intussusception in the proximal gastrointestinal tract is uncommon, and gastro-gastric intussusception is extremely rare. We present a case of gastro-gastric intussusception secondary to a primary gastric lymphoma. An 82-year-old female patient presented with acute onset chest pain and vomiting. Abdominal CT revealed a gastro-gastric intussusception. We performed upper gastrointestinal endoscopy, revealing a large gastric mass invaginated into the gastric lumen and distorting the distal stomach. Uncomplicated gastric reposition was achieved with endoscopy of the distal stomach. Histological evaluation of the gastric mass revealed a diffuse large B cell lymphoma that was treated with chemotherapy.
