Spontaneous Bilateral Pneumothorax in a Patient with Anorexia Nervosa: The Management of Prolonged Postoperative Air Leakage

A 24-year-old Japanese female with anorexia nervosa presented to our hospital for bilateral pneumothorax, and 12-Fr thoracostomy catheters were inserted into the bilateral pleural cavities. On hospital day 9, a thoracoscopic bullectomy was performed. However, air leakage relapsed on both sides on postoperative day 1. The air leakage on the right side was particularly persistent, and we switched the drainage to a Heimlich valve. Both lungs expanded gradually and the chest tube was removed on postoperative day 19. Passive pleural drainage might be an option for prolonged air leakage after a bullectomy in patients with anorexia nervosa

Clinical Study on Slight Fever

Between May 1981 and April 1986, 1402 patients were admitted to the Department of Primary Care Medicine of Kawasaki Medical School Hospital. Of these, 452 patients had a slight fever ranging from 37.0°C to 37.9°C. We analyzed those patients clinically. Infection ranked first as the cause of slight fever, followed by malignancy, collagen disease and others. About 50% of the cases were of unknown origin, and many cases with CRP and ESR almost within the normal range convalesced satisfactorily. The measurement of CRP and ESR in slight fever patients were useful to exclude organic slight fever. The cases with a slight fever of unknown origin appearing for a long term also often had nonorganic diseases such as depression or neurosis. Almost all of these cases were placed in the category of habitual hyperthermia

Perforation of intramural gastric metastasis during preoperative chemotherapy in a patient with thoracic esophageal squamous cell carcinoma

AbstractIntroductionPerforation of intramural metastasis to the stomach (IMS) from esophageal cancer during chemotherapy has not been reported.Presentation of caseA 68-year-old male consulted our hospital due to appetite loss. He was diagnosed with advanced esophageal squamous cell carcinoma in the lower thoracic esophagus along with a large IMS in the upper stomach. The patient received preoperative chemotherapy of docetaxel, cisplatin, and 5-fluorouracil (DCF). During the second cycle of DCF, he had upper abdominal pain and was diagnosed with gastric perforation. Omental implantation repair for the perforation, peritoneal drainage, tube-gastrostomy, and tube-jejunostomy were performed.At 24 days after emergency surgery, he underwent thoracoscopic radical esophagectomy with total gastrectomy and reconstruction with colonic interposition. Pathological findings in the esophagus demonstrated complete replacement of the tumor by fibrosis. The gastric tumor was replaced by scar tissue with multinucleated giant cells along with a small amount of viable cancer cells. The patient was alive and healthy at 14 months after the radical operation, without tumor recurrence.DiscussionThe gastric perforation occurred due to rapid regression of the IMS which had involved the whole gastric wall before chemotherapy. Close monitoring to detect rapid tumor shrinkage during chemotherapy in patients with IMS may be warranted. A two-step operation was proposed to achieve safe curative treatment in patients with perforation of IMS during preoperative chemotherapy.ConclusionWe describe the first reported case of a patient with esophageal squamous cell carcinoma who showed perforation of IMS during preoperative chemotherapy

Prolonged warm ischemia exacerbated acute rejection after lung transplantation from donation after cardiac death in a mouse

Objective: In lung transplantation (LTx) from donation after cardiac death (DCD), the donor lungs are inevitably exposed to warm ischemic time (WIT) between the cardiac arrest and the initiation of cold preservation. We conducted this study to examine the effect of prolonged WIT on lung allograft rejection in a murine model of LTx from DCD. Methods: Allogeneic BALB/c → B6 LTx from DCD was performed with a WIT of 15 min (WIT15 group, n = 5) or 60 min (WIT60 group, n = 5). Recipients were immunosuppressed by perioperative costimulatory blockade. The lung allografts were analyzed by histology and flow cytometry on day 7 after the LTx. Results: Histologically, the rejection grade in the WIT60 group was significantly higher than that in the WIT15 group (3.4 ± 0.4 vs. 2.2 ± 0.2, P = 0.0278). Moreover, the intragraft CD8+ to CD4+ T cell ratio in the WIT60 group was significantly higher than that in the WIT15 group (2.3 ± 0.12 vs. 1.2 ± 0.11, P Conclusions: Prolonged WIT could exacerbate the severity of lung allograft rejection after LTx from DCD. Minimization of the WIT could improve the outcomes after LTx from DCD
