Purpose: Since sustained cough causes great distress to cancer patients, it is important to palliate this symptom. Here, we report a case of intractable cough that could not be controlled by morphine but was successfully managed using continuous infusion of lidocaine for 1 year. Case: A female patient suffered from breast cancer in her fifties. Its lung metastasis invaded endobronchial space, causing frequent and sustained coughing. Further, coughing was often induced by her body motion, hampering the patient's quality of life. Morphine hydrochloride up to a dose of 480mg/day was ineffective in alleviating this symptom. Therefore, we started lidocaine administration via continuous infusion at a dose of 480mg/day. From the day administered, both frequency and duration of her coughing bouts were markedly reduced. Although its dose was increased to 960mg/day because of aggravated coughing in the course of her disease, the symptom was successively managed for 1 year with no side effects. Conclusion: Continuous and long-term infusion of lidocaine could be an alternative treatment for morphine-ineffective intractable cough. Palliat Care Res 2008;3(1):305-307

Insomnia in advanced cancer patients has a highly negative impact on the patients, their families and caregivers. Insomnia is principally managed by pharmacological therapy; however, most advanced cancer patients are unable to receive oral medications. This prospective audit study investigated the efficacy of single—dose subcutaneous administration of flunitrazepam for treating insomnia in patients with advanced cancer. Sleep evaluation was conducted using the St. Mary’s Hospital Sleep Questionnaire. The primary endpoint was the quality of sleep; the secondary endpoints comprised other subscales of total sleep time, sleep latency and adverse effects. We enrolled 30 patients. The average dose of flunitrazepam dose was 0.9(0.1)mg. The good response rate for the quality of sleep was 90%. The total sleep time and sleep latency were 7.5(3.2)h and 31(9.1)min, respectively. Two patients were newly diagnosed with delirium during the study. The mean respiratory rate decreased(15/min before treatment to 14/min after treatment, P=0.01) without any critical events. Single—dose subcutaneous administration of flunitrazepam may be potentially efficacious and simple in treating insomnia in advanced cancer patients.

Two patients with spondylosis deformans and three patients with psychosomatic disease were treated by partial bathing with artificial spring of sodium sulfate. Fifteen minutes a day of bathing in artificial spring water prepared by dissolving 1000mg of sodium sulfate into 1 liter of 38°C-tap water was continued for one month.
Based on the findings on thermography, temperature changes were classified into four types. Correlation was found in three types as follows: p<0.01 in the crossing type, p<0.01 in the converging type, p<0.001 and p<0.05 in the ascending type. No correlation was found in the diffusing type. Plethysmography revealed a significant difference in the converging type and also a difference of p<0.01 in the diffusing type. MCV disclosed a slower change in temperature on the affected side than on the normal side. Blood gas analysis revealed a slight increase in PO2, SATO2 after one month of bathing. Subjective symptoms were improved from point 9 to point 3 to 4 on the VAS scale. Numbness changed from the trembling stage to the slightly smarting sensation stage. Psychroesthesia disappeared from all patients.
A combination of nerve block therapy and warm bath cure with sodium sulfate brought good therapeutic results in patients with chronic pain including psychosomatic disease.

Objective: In The Hospital of Hyogo College of Medicine, a oral rinse containing polaprezinc (PZ), a zinc-containing drug for gastric ulcers, was used as a hospital preparation to treat radiotherapy-related oral mucositis, and its efficacy was reported. However, the dispersibility of PZ for carboxymethylcellulose sodium (CMC), which was used as the base of the oral rinse, was unfavorable, raising an issue. In this study, we newly prepared a PZ oral rinse containing carboxyvinyl polymer (CP) as a base, and examined its usefulness.
Methods: A questionnaire survey regarding the usefulness involving 10 healthy volunteers and a pharmaceutical test were conducted.
Results: The results of the questionnaire survey showed that the optimal concentration of CP was 0.5%. There were no serial changes in the pH, adhesiveness, or PZ content for 7 days after preparation. Furthermore, there were no differences between CMC and CP. The dispersibility of PZ in the oral rinse containing CP as a base was more favorable than that in the oral rinse containing CMC.
Conclusion: The results of this study suggest that the PZ oral rinse containing 0.5% CP as a base is useful, and that its stability is similar to that of the oral rinse containing CMC as a base.

Objective: Oral mucositis is one of the serious and frequent acute side effects due to chemoradiotherapy (CRT) for head and neck cancer. In this study, we prepared an oral rinse as a hospital preparation for the treatment of oral mucositis, which was a suspension of polaprezinc (PZ), a zinc-containing therapeutic agent for gastric ulcer, in carboxyvinyl polymer (CP), a water-soluble large molecule.
Methods: We carried out stability tests of the PZ-CP oral rinse, and investigated its effects on the radiation-induced oral mucositis in patients who received CRT for head and neck cancer.
Results: In the stability test, the pH, viscosity, adhesion and PZ content in the preparations did not change throughout 28 days after preparation. In the clinical evaluation on the basis of the distribution of the Grade of oral mucositis, the Grade of oral mucositis in the PZ group was significantly lower than in the control group at 6 and 7 weeks (p=0.016, p=0.018). The incidence of severe oral mucositis of Grade 3 was 15.0% (3 cases) in the PZ group and 41.7% (10 cases) in the control group at 6 weeks, and was 15.0% (3 cases) in the PZ group and 33.3% (8 cases) in the control group at 7 weeks.
Conclusion: These results suggest that PZ-CP oral rinse inhibits the aggravation of oral mucositis induced by CRT or promotes its healing.

Guanylyl cyclase C (GC-C) is a member of a family of enzymes that metabolize GTP to cGMP and was first identified as a receptor for heat-stable enterotoxin. Guanylin (GNY) has since been identified as an endogenous ligand for GC-C in the intestine of several mammalian species. The GNY/GC-C system regulates ion transportation and pH in the mucosa. Recently, it was reported that GC-C and GNY are involved in lipid metabolism in rat mesenteric adipose tissue macrophages. To examine the role of GC-C and GNY in lipid metabolism in cattle, we used a bovine mesenteric adipocyte primary culture system and a coculture system for bovine adipocytes and GNY-/GC-C-expressing macrophages. Fat droplets were observed to accumulate in bovine mesenteric adipocytes cultured alone, whereas few fat droplets accumulated in adipocytes indirectly cocultured with macrophages. We also observed that GC-C was present in bovine mesenteric adipose tissue, and that fat droplet accumulation decreased after in vitro GNY administration. Expressions of mRNAs encoding lipogenic factors decreased significantly in adipocytes after either coculture or GNY administration. These results suggest that the GNY/GC-C system is part of the control system for lipid accumulation in bovine mesenteric adipose tissue.

In late August 2014, three autochthonous dengue cases were reported in Japan. Since then, as of 17 September 2014, a total of 131 autochthonous cases have been confirmed. While cases were reported from throughout Japan, the majority were linked to visiting a large park or its vicinity in Tokyo, and the serotype detected has been serotype 1. We report preliminary findings, along with the public health response activities, of the first documented autochthonous dengue outbreak in Japan in nearly 70 years.Dengue is an acute, mosquito-borne febrile illness caused by a flavivirus found widely in the Asia-Pacific region, particularly in South-East Asia. While the most competent mosquito species for dengue virus transmission is believed to be

An inflammatory fibroid polyp (IFP) is a mesenchymal tumor of the gastrointestinal tract. IFPs in the small intestine are the most frequently detected with symptoms, such as abdominal pain and tarry stool due to intussusception. Accordingly, few studies have reported jejunal IFP as a cause of occult gastrointestinal bleeding (OGIB) diagnosed via both of capsule endoscopy (CE) and double-balloon enteroscopy (DBE). A 68-year-old woman presented with a progression of anemia and a positive fecal occult blood test result. Esophagogastroduodenoscopy and total colonoscopy findings were unremarkable. CE revealed a tumor with bleeding in the jejunum. DBE also revealed a jejunal polypoid tumor. Bleeding from the tumor seemed to have caused anemia. The patient underwent partial laparoscopic resection of the jejunum, including resection of the tumor. The tumor was histopathologically diagnosed as IFP. To our knowledge, this is the first reported case of laparoscopic resection of jejunal IFP with OGIB diagnosed via CE and DBE preoperatively.
