Short-time ultrasound of head and neck squamous cell carcinoma under radiotherapy.

To evaluate the efficacy of ultrasonography for patients with head and neck squamous cell carcinoma before and during radiotherapy (RT), consecutive patients with macroscopic lesions were examined before and during RT. Each scan was performed percutaneously in a short time (less than 5 min). The demonstration rate of primary tumors and the largest node of previously known metastatic cervical nodes were measured. Of all 190 patients, 91 primary tumors were detected (47.9%). Primary tumors in oral cavity, oropharynx, hypopharynx and cervical esophagus were determined in over 70% and, for those of nasopharynx and larynx, the demonstration rates were 30% or less. Nodal metastases were visualized in 78 of 80 patients with regional metastases (97.5%). Using the above information, 73 patients (38.4%) received the benefit of radiation therapy. Short-time sonography is a valuable modality for patients with selected sites of head and neck cancers.

Acute traumatic injury of the distal descending aorta associated with thoracic spine injury.

A rare case of traumatic injury of the distal descending aorta associated with thoracic spine injury is reported. A 21-year-old man was admitted after a traffic accident. Thoracic CT and angiography demonstrated a false aneurysm of the distal descending aorta and a compression fracture of the eleventh thoracic vertebra. At emergency surgery, a transverse linear tear at the level of the aortic hiatus was confirmed and repaired.

Mesenteric schwannoma.

Schwannoma is a benign neurogenic tumor arising from the sheath of peripheral nerves. It occurs very rarely in the mesentery, where it is difficult to diagnose. Herein we describe a case in which contrast-enhanced CT and gadolinium-DTPA-enhanced MR showed a locally enhanced well-defined tumor with a cystic component just anterior to the duodenum. These findings corresponded well to the resected specimen.

Primary leiomyoma of the ovary: a case report.

The imaging features of primary ovarian leiomyoma have seldom been described because of the very low prevalence of the tumor. Herein we present a case report on its magnetic resonance imaging features. Both T1- and T2-weighted images revealed a low-signal-intensity mass, which was well circumscribed and sharply demarcated from the uterus. Magnetic resonance imaging was useful in distinguishing it from a malignant ovarian tumor and uterine leiomyoma.

Efficacy of amino acid infusion for improving protein metabolism after surgery: a prospective randomized study in patients undergoing subtotal gastrectomy.

BACKGROUND: Appropriate regimens of peripheral parenteral nutrition (PPN) have been proposed for the improvement of protein metabolism after surgery. When evaluating the efficacy of administered nutrients, it is vital to consider the severity of surgical stresses to avoid confounding effects of the trauma on the postoperative metabolism. This study was designed to evaluate protein-sparing regimens through PPN in patients who had undergone subtotal gastrectomy. STUDY DESIGN: Patients hospitalized at our institutes for gastric cancer were randomly divided into the following five groups and received PPN for 7 days after surgery: 1. G group (n = 9), 200 g glucose (per day); 2. AG group (n = 10), 54 g amino acids + 150 g glucose; 3. AGG group (n = 9), AG + 110 g glucose; 4. AGF group (n = 10), AG + 40 g fat; and 5. AGL group (n = 7), 58 g amino acids + 60 g glycerol. Biochemical studies were done before and after surgery. RESULTS: In comparison to G group patients, AG group patients showed less negative cumulative nitrogen balances. No significant differences in cumulative nitrogen balances were observed between AGG, AGF, and AGL groups. Restoration of the reduced serum rapid turnover protein occurred earlier in the AGL group than in either the AGG or the AGF groups. Hyperglycemia, glucosuria, and hyperinsulinemia were prominent in the AGG group, and less prominent in the AGL group. Marked ketosis together with an increase in serum-free fatty acid levels was found in the AGL group. CONCLUSIONS: These results suggest that in patients who have undergone major elective surgery, infusion of amino acid solutions is advantageous for improving protein metabolism after surgery, and nonprotein energy source and intake are not essential when combined with amino acid solutions for improving nitrogen balance after surgery.

Transcatheter arterial embolization as treatment for life-threatening maxillofacial injury.

A rare case of massive maxillofacial hemorrhage, which was controlled by transcatheter arterial embolization, is reported. A 23-year-old man with massive nasal and oral hemorrhage caused by maxillofacial fracture was admitted. Emergency angiography demonstrated extravasation of contrast material from the posterior superior alveolar artery, which was immediately embolized using gelatin sponge particles. This case shows that transcatheter arterial embolization is useful and effective for the treatment of massive hemorrhage resulting from severe maxillofacial injury.
