Adequate staffing must be assured to achieve better quality of care and job outcomes.

BACKGROUND AND PURPOSE:In the early stages of idiopathic Parkinson disease, motor symptoms are usually asymmetric. We aimed to assess the feasibility of nigrosome 1 detection at 3T MR imaging to analyze the agreement of its asymmetry and clinical laterality.

Objectives: Regardless of its negative impact on quality of life, little is known about the importance of alopecia from the patients' perspective. This study aimed to explore the whole experience of chemotherapyinduced alopecia among Korean breast cancer patients including perception, attitudes, preparedness, and changes after alopecia. Methods: Patients expected to experience or had experienced alopecia were recruited at a tertiary hospital in Seoul, Korea. Semi-structured in-depth interviews were performed in 21 patients. Recurrent issues were identified and placed into thematic categories. Results: All patients think that appearance is important and they pay attention to how they look like. They had negative perceptions about alopecia. Patients were not well prepared for alopecia, and experienced substantial physical, psychological and social distress. Lack of information and limited social support combined with negative images of cancer made it difficult for patients to overcome the trauma and deterred them from usual daily activities resulting in poor quality of life. Conclusions: Patients were not well prepared for alopecia and negative perceptions, lack of preparedness, and limited social support and resources increased alopeciarelated distress. Educational programs for preparing patients to cope with alopecia distress and advocate activities to change people's negative perception about alopecia are needed to reduce the burden imposed by alopecia in cancer patients.

Mutations in five PARK genes (SNCA, PARKIN, DJ-1, PINK1, and LRRK2) are well-established genetic causes of Parkinson disease (PD). Recently, G2385R substitution in LRRK2 has been determined as a susceptibility allele in Asian PD. The objective of this study is to determine the frequency of mutations in these PARK genes in a Korean early-onset Parkinson disease (EOPD) cohort. The authors sequenced 35 exons in SNCA, PARKIN, DJ-1, PINK1, and LRRK2 in 72 unrelated EOPD (age-at-onset ≤50) recruited from ten movement disorders clinics in South Korea.

To investigate the bilateral effects of unilateral subthalamic nucleus deep brain stimulation (STN-DBS), we prospectively studied 9 consecutive advanced Parkinson’s disease (PD) patients (2 men and 7 women) who underwent unilateral STN-DBS. Patients were evaluated preoperatively and at 3 and 6 months postoperatively with and without dopaminergic medications (‘on’ and ‘off’ medication, respectively). Postoperatively, patients were assessed with and without stimulation. We found that, when compared with baseline, the ‘off’ medication scores of the Unified Parkinson’s Disease Rating Scale motor part (UPDRS III) and activities of daily living (UPDRS II) were improved by 37% (p = 0.028) and 50% (p = 0.046) at 6 months after surgery, respectively. Stimulation while ‘off’ medication improved the total UPDRS score by 42% (p = 0.028) at 6 months. At 6 months after surgery, the subscore of UPDRS III of body parts contralateral to the DBS implantation had improved by 48% (p = 0.028), and the ipsilateral subscore of UPDRS III and the axial subscore of UPDRS III had improved by 20% (p = 0.027) and 39% (p = 0.028), respectively. Daily dosage of levodopa was reduced by 15% at 6 months. No patient exhibited permanent side effects. These findings indicate that unilateral STN-DBS may be a reasonable surgical procedure for selected PD patients who have markedly asymmetric parkinsonism.

Purpose To explore the utility of nigrosome 1 with 3-T magnetic resonance (MR) imaging to differentiate idiopathic Parkinson disease (IPD) from drug-induced parkinsonism (DIP). Materials and Methods The institutional review board approved this study, and participants gave informed consent. This study enrolled patients with DIP (n = 20) and IPD (n = 29) who underwent N-3-fluoropropyl-2-β-carbomethoxy-3-β-(4-iodophenyl)nortropane ((18)F-FP-CIT) positron emission tomography (PET) and healthy participants (n = 20). All participants underwent 0.5 × 0.5 × 1.0 mm(3) oblique axial three-dimensional multiecho-data image combination imaging to view the nigrosome 1 with 3-T imaging. Two reviewers independently assessed the nigrosome 1 without clinical information. DIP was diagnosed when no abnormality was seen at (18)F-FP-CIT PET. Diagnostic sensitivity, specificity, and accuracy of the nigrosome 1 imaging were evaluated between the IPD and DIP patients and between the IPD patients and healthy participants. Interrater agreement was assessed with Cohen κ. Results Both reviewers agreed in 63 of 69 participants (91.3%) for the presence of any abnormality on either side of the nigrosome 1 (κ = 0.825). Findings in all 29 IPD patients (100%) and three of 20 DIP patients (15%) were rated as abnormal and in 17 of 20 DIP patients (85%) they were interpreted as normal on the basis of imaging of the nitgrosome 1 (sensitivity, 100% (29 of 29); specificity, 85.0% (17 of 20); accuracy, 93.9% (46 of 49) between IPD and DIP patients). Findings in 3 of 20 healthy participants (15.0%) were interpreted as abnormal on the basis of imaging the nigrosome 1 while in the other 17 of 20 healthy participants (85.0%) they were rated as normal (sensitivity, 100% [29 of 29]; specificity, 85.0% [17 of 20]; accuracy, 93.9% [46 of 49] between IPD patients and healthy participants [κ = 0.831]). Conclusion The imaging of nigrosome 1 with 3-T imaging can differentiate DIP from IPD with high accuracy and may help to screen patients who need dopamine transporter imaging in those suspected of having DIP.
