Population-Based Study of the Incidence and Mortality Rate of Acute Aortic Dissection.

Background: Acute aortic dissection (AAD) has high morbidity and a high fatality rate for a cardiovascular disease. Recent studies suggested that the incidence of AAD is increasing. However, the actual incidence and mortality rates of AAD are not well known.

[A Case of Long-Term Survival Following Multidisciplinary Therapy for Small Intestinal Metastasis of Bladder Cancer].

The patient was a 70-year-old man who underwent transurethral resection of a bladder tumor. The pathological diagnosis was urothelial carcinoma (UC) with sarcomatoid variant, ≧pT2. After neoadjuvant chemotherapy using gemcitabine and cisplatin (GC), radical cystectomy was performed.

[Malignant Peritoneal Mesothelioma Diagnosed as an Inguinal Mass : A Case Report].

Malignant peritoneal mesothelioma is generally characterized by chief complaints such as abdominal mass and abdominal pain. We report a case of malignant peritoneal mesothelioma diagnosed as an inguinal mass. A 69-year-old man was referred to our hospital complaining of abdominal distension and swelling in the right inguinal region.

A higher De Ritis ratio (AST/ALT) is a risk factor for progression in high-risk non-muscle invasive bladder cancer.

Background: High-risk non-muscle invasive bladder cancer (NMIBC) is thought to be associated with a higher risk of recurrence and progression. A recent study revealed that a high De Ritis ratio was a risk factor in some solid malignancies. This study examined the importance of the De Ritis ratio as a prognostic marker in high-risk NMIBC.

Hypogenesis of right hepatic lobe in a laparoscopic cholecystectomy for acute gallstone cholecystitis: A case report.

Hypogenesis or agenesis of right hepatic lobe is a rare abnormality and is generally associated with gallbladder and biliary tract abnormalities. Cases of biliary injury following cholecystectomy have been reported in patients with agenesis of right hepatic lobe because the anatomical anomalies complicate the surgical approach. We report a case of laparoscopic cholecystectomy in a patient with hypogenesis of right hepatic lobe.

Longitudinal changes over 2 years in parotid glands of patients treated with preoperative 30-Gy irradiation for oral cancer.

Objective: To evaluate longitudinal changes in parotid volumes and saliva production over 2 years after 30 Gy irradiation.

Methods: We retrospectively evaluated 15 assessable patients treated for advanced oral cancer. Eligibility criteria were a pathologic diagnosis of squamous cell carcinoma, preoperative radiation therapy with a total dose of 30 Gy delivered in 15 fractions, and the availability of longitudinal data of morphological assessments by computed tomography and functional assessments with the Saxon test spanning 2 years after radiation therapy.

Acute adrenal hemorrhage after blunt trauma.

Objective: To determine the appropriate management of adrenal hemorrhage in patients with severe chest and upper abdominal blunt trauma.

Materials And Methods: We reviewed 7 patients who suffered from severe traumatic adrenal hemorrhage after a traffic accident (n = 4) or fall (n = 3). Contrast-enhanced CT images were analyzed for multi-organ traumatic injury, hematoma size, extravasation, and pseudoaneurysm formation.
