Comparative Study
Curative-Intent Aggressive Treatment Improves Survival in Elderly Patients With Locally Advanced Head and Neck Squamous Cell Carcinoma and High Comorbidity Index.
For locally advanced head and neck squamous cell carcinoma (HNSCC), therapeutic decisions depend on comorbidity or age. We estimated the treatment outcomes of patients with different Charlson comorbidity index (CCI) scores and ages to determine whether aggressive treatment improves survival. Data from the Taiwan National Health Insurance and cancer registry databases were analyzed, and we included >20-year-old patients with American Joint Committee on Cancer (AJCC) stage III or IV HNSCC (International Classification of Diseases, Ninth Revision, Clinical Modification codes 140.0-148.9) undergoing surgery, chemotherapy (CT), radiotherapy (RT), concurrent chemoradiotherapy (CCRT), sequential CT and RT, or surgery with adjuvant treatment. ⋯ After adjustment for age, sex, and clinical stage, adjusted hazard ratios (95% confidence intervals) of overall death in Group 1 were 0.33 (0.31-0.35), 0.34 (0.31-0.36), and 0.37 (0.28-0.49), and those of all-cause death among patients undergoing curative surgical aggressive treatments were 1.13 (0.82-1.55), 0.67 (0.62-0.73), and 0.49 (0.46-0.53) for CCI scores of ≥10, 5 to 9, and <5, respectively. Aggressive treatments improve survival in elderly (≥65 years) and critically ill HNSCC patients. Curative nonsurgical aggressive treatments including definitive RT or CCRT might be suitable for HNSCC patients with CCI scores ≥10.

Descending Control of Nociceptive Processing in Knee Osteoarthritis Is Associated With Intracortical Disinhibition: An Exploratory Study.
Based on the hypothesis that an imbalance in excitatory and inhibitory input is a central mechanism of knee osteoarthritis chronic pain (KOACP), this exploratory study had the following aims: to compare whether the function of the descending inhibitory pain pathway is associated with the state of inhibition in the corticospinal system indexed by the motor-evoked potential (MEP) and the cortical salient period (CSP) in patients with severe osteoarthritis (OA) and healthy controls; and to determine if there is correlation between the measures of intracortical inhibition (CSP, MEP) with changes on the numerical pain scale (NPS [0-10]) in KOACP during a conditioned pain modulation (CPM)-task considering the effect of self-reported function assessed by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and analgesic use. In a cross-sectional study, we included females (n = 21), with disability by pain or stiffness due to KOACP and healthy controls (n = 10), aged 19 to 75 years. The motor cortex excitability parameters (MEP and CSP) were assessed using the transcranial magnetic stimulation. ⋯ Also, the CSP was negatively correlated with the pain and disability assessed by the WOMAC index. These findings support the hypothesis that the change in cortical plasticity in KOACP is associated with less intracortical inhibition, as measured by the CSP. These results show that the neural change in the motor cortex in KOACP is associated with pain and disability levels, and also with decreased activation of the endogenous pain-modulating system by a CPM-task.

Efficacy and Safety of Trabectome Surgery in Chinese Open-Angle Glaucoma.
To investigate the clinical outcome of the Trabectome in Chinese open-angle glaucoma (OAG). This prospective case series recruited pseudophakic glaucoma subjects with open-angle configuration. Trabeculectomy ab interno was performed using the Trabectome to 120° of the trabecular meshwork. ⋯ There were no intraoperative complications. 26.3% of subjects had a transient IOP spike > 21 mm Hg, 1 had hyphema requiring washout, and 1 had reactivation of herpetic keratitis. The success rate at 6 months was 89.5%. Trabectome achieved a modest reduction in IOP and medications in the majority of pseudophakic Chinese OAG eyes.

Clinical studies have shown that bismuth-containing quadruple therapy given twice a day for 10 to 14 days is effective and safe in the treatment of Helicobacter pylori infection in Sardinia. However, bismuth is no longer available in Italy. To report the effectiveness and tolerability of pantoprazole 20 mg, tetracycline 500 mg, and metronidazole 500 mg given b.i.d. (with the midday and evening meals) for 10 days supplemented with Lactobacillus reuteri (DSM 17938) 10(8) cfu/tablet once a day for 20 days in patients treated in a routine daily practice setting. ⋯ Side effects were absent or generally mild. Proton pump inhibitor-tetracycline-metronidazole-L reuteri therapy provided high eradication rates with few side effects and therefore can safely replace bismuth in H pylori treatment. Further studies are needed that include susceptibility testing.

Prognostic Effects of Adjuvant Chemotherapy-Induced Amenorrhea and Subsequent Resumption of Menstruation for Premenopausal Breast Cancer Patients.
Chemotherapy-induced amenorrhea (CIA) is a side effect that occurs in patients with breast cancer (BC) as a result of chemotherapy. These patients require special treatments to avoid infertility and menopause. However, the factors controlling CIA, resumption of menstruation (RM), and persistence of menstruation after chemotherapy are unknown. ⋯ Multivariate analysis indicated that tumour size ≥2 cm remained as a significant factor for DFS (hazard ratio = 3.3, P = 0.034). In summary, this study finds that the majority of premenopausal patients with BC (stage I to stage III) who receive chemotherapy experience CIA and subsequent RM. Although tumour size ≥2 cm is negatively associated with DFS, RM after CIA is not associated with poor prognosis.
