The effectiveness of the mental health social worker-led multiprofessional program in preventing long-term hospitalization and readmission in acute psychiatric inpatients in Japan: A retrospective analysis.

Aim: The large number of new long-stay (NLS) patients and high readmission rates in psychiatric hospitals are longstanding concerns in Japan despite reforms to encourage multidisciplinary support of such patients. Staffing shortages of specialists, especially mental health social workers (MHSWs), may be one of the reasons for these problems to remain unsolved.

Methods: The authors examined the effectiveness of the MHSW-centered multidisciplinary care model in preventing NLSs and rehospitalization in terms of both patient dynamics and cost by retrospective comparison of before and after program implementation.

Randomised controlled trial on the effect of video-conference cognitive behavioural therapy for patients with schizophrenia: a study protocol.

Introduction: Cognitive behavioural therapy for psychosis (CBTp) has demonstrated effectiveness in reducing positive symptoms, improving depression, enhancing coping skills and increasing awareness of illness. However, compared with cognitive behavioural therapy for depression and anxiety, the spread of CBTp in clinical practice is minimal. The present study designed a randomised controlled trial (RCT) research protocol to evaluate whether real-time remote video-conference CBTp (vCBTp) could facilitate access to psychosocial interventions and effectively improve symptoms compared with usual care (UC) for patients with schizophrenia.

Oxytocin system dysfunction in patients with treatment-resistant schizophrenia: Alterations of blood oxytocin levels and effect of a genetic variant of OXTR.

Treatment-resistant schizophrenia (TRS) has a quite complex pathophysiology that includes not only severe positive symptoms but also other symptom domains. Much attention has been devoted to the overlapping psychological and biological profiles of schizophrenia and autistic spectrum disorder (ASD). We compared TRS patients (n = 30) with schizophrenia patients in remission (RemSZ, n = 28) and ASD patients (n = 28), focusing on general cognitive and social cognitive impairment and oxytocin system dysfunction.

Successful rechallenge with paliperidone after clozapine treatment for a patient with dopamine supersensitivity psychosis.

We describe the case of a 49-year-old Japanese male patient successfully treated with a paliperidone rechallenge following 2-year treatment with clozapine for treatment-resistant schizophrenia. He had responded well to conventional antipsychotic treatment for the initial psychotic episode but gradually developed dopamine supersensitivity; even treatment with paliperidone and another antipsychotic medication (a total up to 1700 mg in chlorpromazine-equivalent dose) had not improved his psychotic symptoms. Clozapine treatment produced temporary symptomatic relief, but the clozapine dose could not be increased to > 150 mg due to the patient's intolerance.

Increased Serum Levels of Oxytocin in 'Treatment Resistant Depression in Adolescents (TRDIA)' Group.

Objective: 'Treatment-resistant depression' is depression that does not respond to an adequate regimen of evidence-based treatment. Treatment-resistant depression frequently becomes chronic. Children with treatment-resistant depression might also develop bipolar disorder (BD).

Risperidone long-acting injectable in the treatment of treatment-resistant schizophrenia with dopamine supersensitivity psychosis: Results of a 2-year prospective study, including an additional 1-year follow-up.

Unlabelled: Dopamine supersensitivity psychosis (DSP) resulting from antipsychotic treatment is related to treatment-resistant schizophrenia (TRS), and its treatment has not been established to date. Maintaining thoroughly stable occupancy of the dopamine D2 receptor by risperidone long-acting injectable (RLAI) is one strategy for treatment. In this study, RLAI was given as an adjunctive medication to oral antipsychotic(s), which were switched partially and gradually to RLAI in 108 treatment-resistant patients for an additional 1-year follow-up in a 2-year study, and to compare the effects in 72 patients with a DSP history (DSP group) and 36 patients without this history (NonDSP group).

Milnacipran treatment and potential biomarkers in depressed patients following an initial SSRI treatment failure: a prospective, open-label, 24-week study.

Background: We assessed the effect of switching patients with major depressive disorder to milnacipran following an initial selective serotonin reuptake inhibitor treatment failure, and explored potential biomarkers in their blood.

Methods: We conducted a prospective, open-label, 24-week trial. Depression was assessed with the 17-item Hamilton Depression Rating Scale.

Decreased levels of serum oxytocin in pediatric patients with Attention Deficit/Hyperactivity Disorder.

Attention Deficit/Hyperactivity Disorder (ADHD) and autism spectrum disorder (ASD) are highly comorbid, and both disorders share executive function deficits. Accumulating evidence suggests that ASD patients have significantly lower peripheral oxytocin (OXT) levels compared with their normal counterparts, and that the repetitive behavior seen in ASD is related to abnormalities in the OXT system. In this study, we investigated whether serum levels of OXT are altered in pediatric patients with ADHD.

A prospective comparative study of risperidone long-acting injectable for treatment-resistant schizophrenia with dopamine supersensitivity psychosis.

Objective: Dopamine supersensitivity psychosis (DSP) is considered to be one cause of treatment-resistant schizophrenia (TRS). The authors investigated the efficacy of risperidone long-acting injections (RLAI) in patients with TRS and DSP.

Method: This is a multicenter, prospective, 12-month follow-up, observational study that included unstable and severe TRS patients with and without DSP.

Tipepidine in children with attention deficit/hyperactivity disorder: a 4-week, open-label, preliminary study.

Background: Tipepidine (3-[di-2-thienylmethylene]-1-methylpiperidine) has been used solely as a nonnarcotic antitussive in Japan since 1959. The safety of tipepidine in children and adults has already been established. It is reported that tipepidine inhibits G-protein-coupled inwardly rectifying potassium (GIRK)-channel currents.

Effectiveness of Information Technology Aided Relapse Prevention Programme in Schizophrenia excluding the effect of user adherence: a randomized controlled trial.

Background: A relapse prevention program called the Information Technology Aided Relapse Prevention Programme in Schizophrenia (ITAREPS) has been developed and is reported to be highly effective. However the effectiveness was influenced by user adherence to the protocol of the program, the exact effectiveness and the role of the ITAREPS have been partially uncertain.

Objective: The purpose of this study is to evaluate the effectiveness of the ITAREPS excluding the effect of user adherence to the protocol of the program.

[Efficacy and safety of maintenance intravesical instillation therapy with bacillus Calmette-Guerin and epirubicin for non-muscle invasive bladder cancer].

The objectives of this study were to evaluate the efficacy and toxicity of maintenance intravesical instillation therapy with bacillus Calmette-Guerin (BCG) and epirubicin for non-muscle invasive bladder cancer. From April 1999 to March 2010, 27 eligible patients were enrolled in this study. After receiving one cycle of epirubicin (100 mg/100 ml) by intravesical instillation, all patients received 6 weekly alternate intravesical instillation of BCG (80 mg/50 ml) and epirubicin (50 mg/50 ml), followed by 10 monthly instillations.

[Initial division of the left renal vein before dissection of left renal vein occluded by intracaval tumor thrombus].

Between November 2008 and March 2010, we performed initial division of the left renal vein occluded by the tumor thrombus in six cases of left renal cancer at Toranomon Hospital. The left renal vein was completely occluded by the tumor thrombus in all cases. In order to ligate the left renal artery first behind the dilated left renal vein, we must dissect the left kidney with arterial blood flow.

Choriocapillary blood propagation in normal volunteers and in patients with central serous chorioretinopathy.

Background/aims: To evaluate early choroidal vascular dye-filling and dye propagation patterns in normal subjects and in patients with central serous chorioretinopathy (CSC) using indocyanine green (ICG) angiography.

Methods: Seventeen healthy volunteers (21-81 years old) and six patients with CSC were included. ICG angiography was performed using a modified Topcon ICG video-camera system.

Conservative management of small renal tumors.

With the widespread use of imaging modalities, incidentally discovered small renal cell carcinomas have increased. Some patients, however, are too old or weak due to various diseases to undergo surgery and other patients occasionally refuse surgery. To investigate the natural history of small renal cell carcinoma, we retrospectively reviewed patients with small renal tumors suggestive of carcinoma.

Usefulness of intravascular ultrasonography for treatment of a ruptured vertebral dissecting aneurysm.

We report successful stent implantation and secondary coil embolization in a wide-necked dissecting aneurysm in the vertebral artery. Intravascular ultrasonography (IVUS) showed the thrombosed pseudolumen clearly and enabled precise determination of the appropriate stent size. After stent implantation, Guglielmi detachable coil embolization was performed.

[Aortic replacement during post chemotherapy retroperitoneal residual tumor resection for nonseminomatous germ cell tumor: a case report].

A 59-year-old man visited our hospital complaining of epigastralgia. A large hard mass was palpable in the abdominal cavity. Abdominal computed tomography revealed large retroperitoneal cystic tumors.

[Outcome of treatment with surgical resection of the remaining tumor after modified M-VAC treatment for advanced urothelial carcinoma].

We retrospectively evaluated the effect of the surgical resection of the remaining tumor after modified M-VAC (methotrexate, vinblastine, doxorubicin and cisplatin) (m-M-VAC) treatment for locally advanced or metastatic urothelial carcinoma. In m-M-VAC therapy, methotrexate and vinblastine on 15 and 22 days were omitted from the classical M-VAC to avoid the discontinuation and the dose reduction, and duration of 1 course was shortened to 21 days from 28 days of the classical M-VAC. Seven patients with locally invasive or metastatic carcinoma of the renal pelvis, ureter, and bladder, 6 males and 1 female, with a median age 64.
