Progressive Encephalomyelitis with Rigidity and Myoclonus Resolving after Thymectomy with Subsequent Anasarca: An Autopsy Case.

Progressive encephalomyelitis with rigidity and myoclonus (PERM) is an autoimmune disorder involving the brainstem and spinal cord and is sometimes associated with thymoma. We encountered a 75-year-old woman with typical PERM features, glycine receptor antibody, and thymoma. Her neurologic symptoms improved after thymectomy, but she unexpectedly developed anasarca with massive pleural effusions and hypoalbuminemia and finally succumbed to death. The autopsy showed edema and mononuclear infiltration in the pleura but no neuropathological findings typical of PERM. Effective treatment of PERM can reverse the neuropathological signs of encephalomyelitis. The autoimmune nature of anasarca is possible but not proven.

Extracorporeal cardiopulmonary resuscitation for blunt cardiac rupture.

Extracorporeal cardiopulmonary resuscitation (ECPR) followed by operating room sternotomy, rather than resuscitative thoracotomy, might be life-saving for patients with blunt cardiac rupture and cardiac arrest who do not have multiple severe traumatic injuries. A 49-year-old man was injured in a vehicle crash and transferred to the emergency department. On admission, he was hemodynamically stable, but a plain chest radiograph revealed a widened mediastinum, and echocardiography revealed hemopericardium. A computed tomography scan revealed hemopericardium and mediastinal hematoma, without other severe traumatic injuries. However, the patient's pulse was lost soon after he was transferred to the intensive care unit, and cardiopulmonary resuscitation was initiated. We initiated ECPR using femorofemoral veno-arterial extracorporeal membrane oxygenation (ECMO) with heparin administration, which achieved hemodynamic stability. He was transferred to the operating room for sternotomy and cardiac repair. Right ventricular rupture and pericardial sac laceration were identified intraoperatively, and cardiac repair was performed. After repairing the cardiac rupture, the cardiac output recovered spontaneously, and ECMO was discontinued intraoperatively. The patient recovered fully and was discharged from the hospital on postoperative day 7. In this patient, ECPR rapidly restored brain perfusion and provided enough time to perform operating room sternotomy, allowing for good surgical exposure of the heart. Moreover, open cardiac massage was unnecessary. ECPR with sternotomy and cardiac repair is advisable for patients with blunt cardiac rupture and cardiac arrest who do not have severe multiple traumatic injuries.

Airway and circulatory collapse due to retropharyngeal hematoma after blunt vertebral artery injury.

Retropharyngeal hematoma following blunt cervical spine injury is a known cause of airway obstruction, but it is not known to cause hemorrhagic shock. We report the case of a massive retropharyngeal hematoma caused by a blunt vertebral artery transection leading simultaneously to airway obstruction and hemorrhagic shock. An 83-year-old woman was injured in a motorcycle accident. In the field, the patient exhibited paradoxical breathing with no breath sounds, and her blood pressure could not be measured. Therefore, emergency intubation and fluid resuscitation were initiated and the patient was transferred to the emergency department. Computed tomography angiography revealed a massive retropharyngeal hematoma with contrast extravasation from the right vertebral artery, which caused airway obstruction and hemorrhagic shock. The right vertebral artery was transected at the C5 level, which was associated with C4/C5 dislocation. Vertebral artery transection was successfully treated by endovascular embolization, which was followed by complication of asymptomatic posterior circulation stroke. Blunt vertebral artery transection can cause massive retropharyngeal hematoma, which can rapidly expand and lead to hemorrhagic shock in addition to airway obstruction. In cases of massive retropharyngeal hematoma with hemorrhagic shock following blunt cervical spine injury, blunt vertebral artery transection should be suspected. If blunt vertebral artery transection is detected and hemorrhagic shock is persistent, endovascular embolization should be performed immediately in addition to emergency intubation.

[Effective transarterial neoadjuvant chemotherapy with paclitaxel (TXL) in a case of locally advanced breast cancer].

The patient was a 49-year-old woman who had locally advanced breast cancer with skin invasion. She was placed on neoadjuvant weekly systemic chemotherapy of TXL (65 mg/m2) and ADM (20 mg/m2). After systemic chemotherapy, she underwent 2 courses of transarterial neoadjuvant chemotherapy of TXL (day 1, 8, 15). We administered TXL (45 mg/m2) into the subclavian artery and TXL (20 mg/m2) into the internal thoracic artery. Although she experienced grade 3 leukopenia during systemic chemotherapy, she experienced only grade 2 alopecia and grade 1 nausea during transarterial chemotherapy. After chemotherapy, she underwent radical mastectomy. We report herein a case in which transarterial neoadjuvant chemotherapy with TXL was effective.

[A case of advanced gastric cancer with invasion of pancreas effectively treated by combined chemotherapy of TS-1 and paclitaxel (TXL)].

The patient was a 55-year-old woman who had unresectable advanced gastric cancer with celiac lymph node metastases and invasion of pancreas. The lesions were considered surgically incurable, so she was placed on neoadjuvant chemotherapy consisting of TS-1 and low-dose CDDP, for a total of 3 courses of TS-1 (100 mg/day, 12 weeks) and 2 courses of low-dose CDDP (10 mg/day, 100 mg). The only side effect of this chemotherapy was light anorexia, and the patient maintained a good QOL. After chemotherapy, the tumor had decreased partially in size, but there was little change in the abdominal lymph node metastases. She was considered to have little response and underwent palliative distal gastrectomy, because of the incomplete dissection of abdominal lymph node metastases. After the operation, she was treated with 2 courses of TS-1 100 mg/day (3 weeks administration and 2 weeks rest) and CDDP 70 mg or 50 mg/body (day 8). She had grade 3 anorexia. After discharge, she was treated by combined therapy of TS-1 100 mg/day (2 weeks administration and 2 weeks rest) and TXL 60 mg/body (day 1, 8, 15). After 2 courses of TS-1/TXL therapy, the abdominal lymph node metastases had decreased in size and the tumor markers were reduced remarkably: CEA 146.1-->26.9 ng/ml, and CA19-9,351.5-->210.6 U/ml. The patient received 5 courses of TS-1/TXL therapy, and she had no trouble with side effects. She maintained a good QOL. TS-1/TXL therapy was associated with few adverse events in hospital visits, and thought to be an effective adjuvant chemotherapy against advanced gastric cancer.
