We report the case of a 19-year-old female with cerebellar ganglioglioma that was diagnosed at 4 years of age. Despite treatment with partial resection, radiation, and chemotherapy, residual tumor slowly expanded into the brainstem and upper cervical cord, resulting in nocturnal hypopnea, progressive tetraparesis, and feeding difficulty during 8-10 years of age. Initiation of temozolomide and bevacizumab was effective in preventing further expansion of the tumor, and the patient has been treated at home and in school with noninvasive positive pressure ventilation and gastrostomy...

A 47-year-old man with progressive anemia possibly due to digestive tract bleeding was referred to our hospital. Contrast-enhanced computed tomography of the abdomen showed a 2-cm tumor lesion arising near the small intestine. Enteroscopy revealed a 3-cm submucosal tumor at the ileum. A gastrointestinal stromal tumor of the small intestine was suspected, and the patient underwent surgery. During the operation, a diverticulum approximately 60 cm orad to the terminal ileum and a tumor at the top of the diverticulum were observed...

Schizencephaly and porencephaly are extremely rare types of cortical dysplasia. Case 1: Prenatal magnetic resonance imaging (MRI) showed wide clefts in the frontal and parietal lobes bilaterally. On postnatal day 3, MRI T2-weighted images showed multiple hypointensities in the clefts and ventricular walls, suggestive of hemosiderosis secondary to intracranial hemorrhage. Case 2: Prenatal MRI showed bilateral cleft and cyst formation in the fetal cerebrum, as well as calcification and hemosiderosis indicative of past hemorrhage...

Background: Tunneled central venous catheters (CVC), called Broviac/Hickman catheter, are widely used in the long-term treatment of pediatric patients. Recently, the percutaneous approach for CVC insertion has become dominant as a less invasive intervention. In this study, we reviewed the mechanical and delayed complications according to different procedures of CVC insertion and assessed the risk factors for complications in CVC insertions for pediatric patients. Methods: A total of 159 pediatric patients (85 males and 74 females) were included in this study...

Background: Ultrasonographic homogeneity is an important differential finding between Warthin tumor and pleomorphic adenoma, two types of benign parotid gland tumors, with the former likely to be heterogeneous and the latter homogeneous. However, differences in the performance of ultrasound machines or the homogeneity cut-off level affect the judgment of ultrasonographic homogeneity. Therefore, in this study, we adopted a novel system for classifying the composition of tumors via ultrasonography, using anechoic area as a substitute for differences in homogeneity to differentiate between Warthin tumors and pleomorphic adenomas...

Background: Recurrence of lung cancer after surgical resection is a major obstacle in the cure and long-term survival of patients and has become the most common cause of death. However, prognostic factors and efficacy of therapy after recurrence remain controversial. We evaluated the prognostic factors of post recurrence survival (PRS) in patients of resected stage I non-small cell lung cancer (NSCLC). Methods: Of the 551 patients who underwent surgery for stage I NSCLC between 2005 and 2013, we reviewed 89 (16...

Cytology by fine-needle cytology is indispensable for diagnosing head and neck tumor, especially for thyroid nodule. There are two methods of fine needle cytology; one of fine-needle aspiration cytology (FNAC and another of fine-needle non-aspiration cytology (FNNAC). These previous procedures has each disadvantage such as the mixing of blood or low yield of cells. We proposed a new technique: selective low-pressure fine needle aspiration cytology (SLOP-FNAC) to overcome the backwards of previous procedures...

Sternal and rib fractures are well-known complications of cardiopulmonary resuscitation (CPR). We experienced a rare case of traumatic gastric perforation associated with CPR that required emergency laparotomy. In this case, we examined whether surgery is essential for gastric perforation associated with CPR. A 67-year-old man experienced cardiopulmonary arrest in the workplace, and bystander CPR was performed by his colleagues. He was then transported by ambulance to our hospital. A large amount of free air was found in the peritoneal cavity on computed tomography at presentation, and perforation of the gastrointestinal tract was suspected...

Tracheal diverticulum is rarely encountered in a clinical setting since almost all patients are asymptomatic. However, its presence may become a problem during esophageal cancer operations in terms of anesthesia and lymph node dissection of superior mediastinum lymphadenectomy. A 70-year-old man with esophageal cancer was referred to our hospital. During thoracoscopic subtotal esophagectomy, we found a cystic lesion connected to the right posterior wall of the trachea. We evaluated the preoperative computed tomography scan during surgery and made a diagnosis of tracheal diverticulum because of the presence of paratracheal air cysts, which had not been noticed preoperatively...

The Ixodidae family of hard ticks has cement-producing and non-cement-producing species. Involved skins of four patients bitten by cement-producing ticks and two by non-cement-producing ticks were histopathologically examined. Those of the latter two patients were also studied immunohistochemically to characterize the infiltrating inflammatory cells. In patients with cement-producing ticks, the cement substance was observed as external cement or outer zone of internal cement, respectively. Coagulative necrosis was present in the epidermis in one patient and from the epidermis to the dermis in another patient...

Endometriosis is a chronic inflammatory disorder associated with pelvic pain and infertility. Because surgical and medical therapies control symptoms, but it is hard to cure completely endometriosis, long term of pharmacologic management is necessary. Norethisterone (NET), one of progestins, has safety profile and advantage that allow long-term use. In this preliminary report, we showed the efficacy of NET in 6 patients with endometriosis. The size of ovarian endometrioma was decreased after treatment with NET for 6 months, and all patients were relieved from dysmenorrhea pain within 6 months, suggesting that NET would be a suitable medication to treat endometriosis...

S-1 is a combination drug of tegafur, gimeracil and oteracil potassium that is designed on the basis of 5- fluorouracil. We report here for the first time that S-1 is a causative agent of drug eruption mimicking shiitake dermatitis. A 58-year-old Japanese man presented with pruritic erythemas arranged in a linear fashion. He had been treated with S-1 for esophageal cancer. Although differential diagnosis included shiitake dermatitis and dermatomyositis, he had not eaten raw shiitake mushroom, and he did not have other cutaneous lesion such as Gottron's sign and abnormalities of peripheral blood examination including Jo-1 antibody and antinuclear antibody...

BACKGROUND: Gastric cancer patients with peritoneal metastasis have an extremely poor prognosis. The aim of the current study was to clarify the predictive factors of a better outcome in gastric cancer patients with peritoneal metastasis. METHODS: We analyzed the records of 2262 gastric adenocarcinoma patients who underwent gastrectomies at our institution between January 1980 and December 2010. RESULTS: The 5-year survival rates for advanced gastric cancer patients with P1 (n = 43), P2 (n = 56), and P3 (n = 36) metastasis were 16...

BACKGROUND: The purpose of this study was to examine the stigma and coping strategies of patients with type 1 diabetes. METHODS: Data were collected from 24 adult patients with type 1 diabetes via in-depth semi-structured interviews that took place in clinic waiting rooms. Qualitative and descriptive data analysis was conducted to identify stigma and coping strategies of patients with type 1 diabetes. RESULTS: Stigma of patients with type 1 diabetes consisted of four categories: (i) "hatred of insulin" due to a treatment-oriented lifestyle after the onset of the disease, (ii) "imperfect body" due to systemic changes caused by the disease, (iii) "social outcast" as a diabetes patient who used to be healthy, and (iv) "poor me," a negative self-image due to the responses and attitudes of others...

BACKGROUND: At the end of 2016, robot-assisted thoracoscopic surgery (RATS) was still not covered by Japanese national health insurance. Therefore, few institutions in Japan perform RATS and even fewer have reported procedures as they occurred earlier. So, we decided to focus on the initial results of RATS for primary lung cancer. METHODS: We retrospectively reviewed 44 patients who underwent RATS for primary lung cancer from January 2011 to August 2016. After mastering the initial procedure, we introduced a completely portal robotic pulmonary resection procedure using a carbon dioxide insufflation system...

BACKGROUND: Although endoscopy and endoscopic ultrasonography are generally used to diagnose the depth of gastric tumor invasion, endoscopy is invasive and frequently results in patient discomfort. Transabdominal ultrasonography (TUS) is noninvasive and may be useful in determining this depth. We investigated the usefulness of TUS in determining the depth of tumor invasion in patients with gastric cancer. METHODS: This retrospective study included 190 patients with gastric cancer and 200 lesions who underwent curative resection at the Department of Gastrointestinal Surgery of Tottori University Hospital from July 2007 to July 2015...

BACKGROUND: Merkel cell carcinomas (MCCs), clinically aggressive neuroendocrine skin cancers, are divided into Merkel cell polyomavirus (MCPyV)-positive and -negative tumors, which show different clinicopathological features and may develop through different mechanisms of carcinogenesis. Aberrant expression of activation-induced cytidine deaminase (AID) as a genomic modulator was demonstrated through pathogen-related NF-κB signal in Helicobacter pylori-associated gastric cancer, adult T cell leukemia/lymphoma (HTLV-1), hepatoma (HCV), and Burkitt lymphoma (EBV)...

BACKGROUND: Diuretics are essential for treating acute decompensated heart failure (ADHF), but the response is inconsistent. This study aimed to clarify whether kidney volume as assessed by ultrasound (US) predicts diuretic resistance in patients with ADHF. METHODS: We enrolled 29 patients with ADHF and 32 controls. Height-adjusted kidney volume was assessed by US. We divided patients into two groups based on the median value of total daily use of furosemide (intravenous dose plus 0...
