Sociability-based fitness approach in Parkinson's disease: Comparison with conventional rehabilitation.

BACKGROUND AND PURPOSE: The effect of a sociability-based fitness approach on parkinsonian disability in patients with Parkinson's disease (PD) was assessed. METHODS: Eighty patients diagnosed with PD were randomly assigned to either the group-based rehabilitation (GBR) group (n = 40) or the individual-based rehabilitation (IBR) group (n = 40). The primary outcome was the difference between the two groups in the mean change from baseline to post-training in the total score on the Unified Parkinson's Disease Rating Scale (UPDRS). The secondary outcomes included the change in mental status and the difference in the mean change from baseline to month 3 and month 6 in the total score on the UPDRS. RESULTS: The mean (±SD) UPDRS scores were 72.0 ± 21.0 in the GBR group and 72.1 ± 18.6 in the IBR group. The UPDRS scores from baseline to post-training were 22.8 ± 13.5 in the GBR group and 10.9 ± 8.8 in the IBR group (difference 11.8 points; 95% confidence interval [CI] 5.0-18.6; p = 0.001). The difference between the groups from baseline to month 3 (difference 10.06 points; 95% CI 3.3-16.8) and the difference between the groups from baseline to month 6 (difference 11.7 points; 95% CI 4.9-18.5) were also significant (p = 0.004 and p = 0.001, respectively). The scores of cognitive function and depression had not changed significantly. CONCLUSIONS: Patients receiving GBR demonstrated significant improvements in parkinsonian symptoms, suggesting that the sociability-based fitness can be applied to clinical treatment by sustaining the motivation in PD.

Retrospective analysis of the clinical efficacy of definitive chemoradiotherapy for patients with hypopharyngeal cancer.

OBJECTIVE: A retrospective analysis was performed to evaluate the clinical efficacy of definitive chemoradiotherapy including intensity-modulated radiotherapy for patients with hypopharyngeal cancer. METHODS: Previously untreated 204 patients with hypopharyngeal cancer were treated with definitive chemoradiotherapy. Of note, 66-70 Gy was delivered to the primary and involved nodes and 36-54 Gy was delivered to the prophylactic lymph node using standard fractionated radiotherapy. One hundred and forty-six patients received induction chemotherapy as a larynx preservation strategy, followed by definitive radiotherapy with or without concurrent chemotherapy. Intensity-modulated radiotherapy was also performed after 2006. RESULTS: The median follow-up time of this cohort was 43.4 months (range; 6.9-151.0). The 3-year overall survival, progression-free survival and larynx preservation survival rates were 78.8% (95% confidence interval; 73.0-85.0), 58.4% (95% confidence interval; 51.8-65.9) and 67.5% (95% confidence interval; 61.0-74.7), respectively. Multivariate analyses identified the following significant prognostic factors: an advanced age, the T category and N category for overall survival, the T category and N category for progression-free survival and the T category for larynx preservation survival. Acute toxicities of Grade 3 or higher were observed in 47 patients (23.0%). Two patients (1.0%) had Grade 4 pharyngeal edema. Suspicious treatment-related death due to lethal pharyngeal hemorrhage occurred in 1 (0.4%) patient. The rates of Grade 2 xerostomia in patients treated with intensity-modulated radiotherapy were 28.1, 17.4 and 9.5% at 6 months, 1 and 2 years after the completion of radiotherapy, respectively. CONCLUSIONS: The efficacy and safety of definitive chemoradiotherapy are considered feasible with sufficient laryngeal preservation.

International prostate symptom score (IPSS) change and changing factor in intensity-modulated radiotherapy combined with androgen deprivation therapy for prostate cancer.

The purposes of this study on prostate cancer are to demonstrate the time course of International Prostate Symptom Score (IPSS) after intensity-modulated radiation therapy (IMRT) combined with androgen deprivation therapy (ADT) and to examine the factor associated with the IPSS change. This study included 216 patients treated with IMRT between 2006 and 2010. Patients were evaluated in three groups according to baseline IPSS as defined by the American Urological Association classification, where IPSSs of 0 to 7, 8 to 19, and 20 to 35 represent mild (n = 124), moderate (n = 70), and severe (n = 22) symptom groups, respectively. The average IPSSs ± standard deviation at baseline vs. those at 24 months after IMRT were 3.5 ± 2.1 vs. 5.1 ± 3.6 in the mild group (P < 0.001), 12.6 ± 3.4 vs. 10.0 ± 6.0 in the moderate group (P = 0.0015), and 23.8 ± 2.9 vs. 14.4 ± 9.1 in the severe group (P < 0.001). Among factors of patient and treatment characteristics, age, IPSS classification, pretreatment GU medications, and positive biopsy rates were associated with the IPSS difference between baseline and 24 months (P = 0.023, < 0.001, 0.044, and 0.028, respectively). In conclusion, patients with moderate to severe urinary symptoms can exhibit improvement in urinary function after IMRT, whereas patients with mild symptoms may have slightly worsened functions. Age, baseline IPSS, GU medications, and tumor burden in the prostate can have an effect on the IPSS changes.

A case of severe hemoptysis after stereotactic body radiotherapy for peripherally located stage I non-small cell lung cancer.

In stereotactic body radiotherapy (SBRT) for centrally located non-small cell lung carcinoma (NSCLC), severe hemoptysis has been reported in several studies. We report here a rare case of hemoptysis after SBRT even though the lung tumor was peripherally located. A lung nodule of a 79-year-old man was accidentally found at the periphery of the left upper lobe. A computed tomography-guided biopsy of this nodule provided confirmation of the diagnosis of poorly differentiated adenocarcinoma. The clinical diagnosis was T1bN0M0, stage I primary lung cancer. The patient was treated with SBRT using helical tomotherapy at a dose of 60 Gy in 6 fractions (i.e., BED10 = 120). He obtained a complete response and did not experience recurrence. However, the patient suffered massive hemoptysis 4.5 years after SBRT. As hypervascularity of a left bronchial artery was observed at the left lung in accordance with SBRT field on bronchial arteriography, a bronchial artery embolization (BAE) procedure was performed. The patient has had no episodes of hemoptysis after BAE. Although SBRT for early stage NSCLC is usually safe and efficient, it is necessary to be careful for late-onset bronchial hemorrhage in SBRT, even for a peripheral tumor.

Hemophagocytic lymphohistiocytosis complicated by central nervous system lesions in a patient with dermatomyositis: a case presentation and literature review.

We report a case of dermatomyositis (DM) and hemophagocytic lymphohistiocytosis (HLH) complicated by central nervous system (CNS) lesions and review eight literature cases of DM and HLH. A 17-year-old woman, admitted to our hospital because of severe muscle weakness and high fever, was diagnosed with DM based on elevated serum levels of muscle enzymes and a typical skin rash. Pancytopenia, high serum ferritin and soluble interleukin (IL)-2 receptor, and hepatosplenomegaly were also noted. Bone-marrow examination was negative for hemophagocytosis. Steroid therapy combined with immunoglobulin i.v. was ineffective against the DM, pancytopenia, hepatic dysfunction, and hyperferritinemia. On the 27th hospital day, seizures and acute respiratory failure occurred. In the course of improving muscle enzyme levels after starting adjunctive treatment with cyclosporine, the patient suffered disturbed consciousness, dyskinesia, and tremor. Brain magnetic resonance imaging (MRI) revealed T2 hyperintense lesions in the pons. Additional cyclophosphamide pulse therapy successfully decreased serum ferritin. Unfortunately, the diffuse alveolar damage (DAD) confirmed by biopsy progressed and the patient died. Autopsy findings revealed DAD throughout both lungs, HLH liver lesions, and a hemorrhagic necrotic lesion of the pons in the brain. Even when pathological examination yields no findings of hemophagocytosis, it is important to comprehensively and rapidly diagnose HLH based on the clinical picture. Because DM complicated by HLH may be associated with abnormal production of cytokines and systemic autoimmune responses, it may be necessary to immediately administer additional immunosuppressive therapy. We describe and discuss the extraordinary, severe form of DM in our patient, along with cases in the literature.

Diffuse alveolar damage in patients with dermatomyositis: a six-case series.

The clinical course of diffuse alveolar damage (DAD) was studied in six consecutive cases of dermatomyositis (DM) based on our hospital records over 8 years. Three patients had severe myopathy at presentation, and the other three patients showed clinically amyopathic DM (CADM). Interstitial pneumonia in all patients developed shortly after they manifested DM. DAD in five deceased patients, which was proven pathologically, did not respond to steroid therapy combined with cyclosporine or tacrolimus. Of these, two patients began receiving combination therapy before suffering respiratory symptoms, and one of them had elevated serum Krebs von der Lungen-6 (KL-6) levels before visible abnormalities appeared on a plain chest X-ray. Only one patient with CADM survived; this patient received intravenously administered pulse cyclophosphamide (IVCY) therapy intravenously for DAD from the early stage. Delayed adjunctive IVCY was ineffective for progressed DAD in the remaining five patients. Elevated serum ferritin levels were observed in all four patients examined and might have predicted the lethal DAD, as in a previous report. In conclusion, promptly beginning IVCY therapy may be beneficial for patients with DM and interstitial pneumonia who show elevated serum levels of ferritin or KL-6 with minimal pulmonary abnormalities.
