1.Pharmacological therapeutics in androgenetic alopecia
Journal of the Korean Medical Association 2020;63(5):277-285
Androgenetic alopecia (AGA) is the most common type of hair loss and affects both men and women. Male pattern hair loss shows characteristic frontal recession and vertex baldness, whereas female pattern hair loss produces diffuse alopecia over the mid-frontal scalp. AGA is mediated by increased androgen susceptibility in affected scalp hairs. 5α-Reductase converts testosterone into dihydrotestosterone, a potent androgen, in the scalp. Both androgen receptors and 5α-reductase have higher expression levels in the balding scalp than in non-affected regions. Increased androgen susceptibility induces hair follicle miniaturization, which leads to the progressive loss of thicker terminal hairs in the balding scalp. Currently, topical minoxidil and oral 5α-reductase inhibitors, such as finasteride and dutasteride, are approved options for the pharmacological treatment of AGA. Topical minoxidil remains the mainstay of therapy for mild to moderate AGA in both men and women. The daily intake of 1-mg finasteride or 0.5-mg dutasteride shows better efficacy than topical minoxidil in regard to hair regrowth in male AGA. Anti-androgens can be used in female AGA wit clinical and biochemical evidence of hyperandrogenism. Patients may be overwhelmed and confused by the variety of treatment options for AGA management, including over-the-count drugs with low evidence quality. Therefore, physicians must be aware of the current guidelines for the management of AGA based on evidence-based approaches to select better options for patients.

Wilson’s disease (WD) is a genetic disease caused by an ATP7B gene mutation. Although dysphagia is known as a neurological manifestation of WD, clinical case reports with post-treatment long-term follow-up are scarce. A 17-year-old male was admitted to hospital complaining of general weakness and swallowing difficulty. He was diagnosed with WD by genetic confirmation. Assessment of the videofluoroscopic swallowing study (VFSS) determined an initial videofluoroscopic dysphagia scale (VDS) score of 48. After 11 months treatment with D-penicillamine and neuromuscular electrical stimulation therapy (NMES) with oromotor exercises, the VDS score improved to 23, especially in the following areas: mastication, apraxia, premature bolus loss, triggering of pharyngeal swallow, and laryngeal elevation. Dysphagia is an early neurological symptom of WD, and is reversible when properly treated with early diagnosis. Thus, since WD is treatable, patients presenting with dysphagia should be indicative of high probability of the disease, and evaluated at the earliest. NMES treatment in combination with D-penicillamine helps to improve the deglutition function in both oral and pharyngeal phases. To investigate the characteristics of dysphagia and the specific clinical efficacy of NMES in WD, further studies with larger number of patients are required.

There are several dimensions of academic burnout experienced by medical and health science college students. The purpose of this study was to examine the effects of academic relationships on academic burnout. Data was collected from 476 Eulji University students using an online survey over 4 days in April of 2018. Of the 264 respondents, 111 studied medicine (42.0%), 105 studied nursing (39.8%), and 48 studied clinical pathology (18.1%). The questionnaire was composed of the following sections: demographics (four questions), general life characteristics (seven questions), academic enthusiasm (eight questions), academic relationships (15 questions), and academic burnout sub-dimensions (partially revised Maslach Burnout Inventory-Student Survey Scale) (11 questions). T-tests and one-way analysis of variance were performed to illustrate the differences among the three departments. The effects of academic relationships and academic enthusiasm on academic burnout were analyzed using linear regression. Comparing the three departments, academic burnout was not found to be statistically significant (p=0.296). However, medical students' academic enthusiasm was significantly lower (p<0.001) and academic relationships were significantly higher (p<0.001) than nursing and clinical pathology students. The difference in academic burnout among the three departments was not significant. However, medical students have stronger academic relationships, while nursing and clinical pathology students were more focused on academics. Relationships and academic enthusiasm contribute to reducing academic burnout. Therefore, strategies need to be developed to deal with academic burnout considering relationship factors.

Torticollis is an abnormal, asymmetric head or neck position which usually caused by imbalance of paracervical muscles. The traumatic torticollis can be caused by following events; atlantoaxial rotatory subluxation, atlantoaxial dislocation, cervical vertebral fractures, and injury to the cervical musculature. Especially, acute traumatic atlantoaxial rotatory subluxation usually presents limitation of cervical range of motion without pain or neurologic deficit. We report a case of a 58 year-old man who developed the acute atlantoaxial rotatory subluxation right after the chiropractic therapy, which induced the limitation of cervical range of motion to 52.5% of normal range. The magnetic resonance image revealed the facture of the odontoid process and the partial injury in transverse ligaments of the atlas. He underwent intramuscular botulinum toxin injection and 10 days of continuous cervical traction 15 hours a day using a 5 kg weight. The range of the cervical motion restored up to 90.2% of normal range.

OBJECTIVE: This study aims to evaluate the efficacy of high-voltage microcurrent therapy in patients with herniated lumbar disc (HLD) presenting radicular or back pain.METHOD: This is a retrospective study with 33 patients who are complaining pain with HLD findings on magnetic resonance image. Microcurrent therapy was applied to leg or paralumbar area. Treatment was conducted for seven minutes with 250~1000 uA intensity as high as the patients could tolerate via stimulating probe with roller type and the frequency was 60 Hz with a sine wave pulse. The visual analogue scale (VAS) was measured just before and after the treatment.RESULTS: The degree of pain reduction (ΔVAS) was 1.6 points after treatment on average. The ΔVAS according to the diagnosis, stenosis, dermatome area, medication, pain site and caudal epidural block was not statistically significant. However, the ΔVAS according to the number of treatments (< 3, ≥ 3 times) showed a statistically significant difference (p=0.04).CONCLUSION: High-voltage microcurrent therapy may help reduce lumbar or lumbosacral radiating pain after the procedure. The effect was better when microcurrent was applied three times or more. This result suggests that the microcurrent would have cumulative effect on reducing radicular or back pain in patients with HLD.

Generalization of learned fear has been considered to be critical for our survival. Patients with anxiety problems show overgeneralization of learned fear, as reflected by defensive physiological responses to harmless stimuli. Together with these physiological responses, conscious feeling of fear is a seminal part of emotional process that is directly related to the suffering of anxiety patients. However, the effect of anxiety on the generalization of conscious feeling remains unclear. We thus focused on the question whether the generalization of conscious feeling of fear depends on individual anxiety level in nonpatient participants. To address this question, we developed a fear generalization paradigm using natural scene images. We found that subjective feeling of fear was generalized to similar stimuli with the conditioned stimuli (CS), and that this generalization of conscious fear was positively correlated with the level of individual anxiety. Anxiety and depression frequently co-occur, but the individual depression level was not correlated with the fear generalization. These suggest that individual anxiety level mainly affects the generalization of conscious fear.

Background:
Topical steroids are the most commonly prescribed anti-inflammatory agents in dermatology, and patients often experience various adverse events of topical steroid application. Patients’ awareness of adverse effects and understanding of coping strategies for these unwanted events are pivotal elements for the safe use of topical steroids.
Objective:
This study aimed to assess the prescribing pattern of topical steroids and patient education for safe use by dermatologists and non-dermatology specialists in Korea.
Methods:
A questionnaire was sent to dermatologists, pediatricians, and other specialists through an online survey.A total of 444 answers were analyzed; then, the numbers were adjusted according to the nationwide proportion of specialists prescribing topical steroids. The total number of respondents was set to 720 after the adjustment.
Results:
Dermatologists prescribed topical steroids to 49% of their patients, while other specialist doctors prescribed to 6.4% of the patients. Mid-potency steroids were most commonly prescribed (52.9%), followed by low/weak potency (37.6%), in adjusted analysis. Overall, 12.5% of all respondents and 14.5% of dermatologists reported adverse events due to topical steroids within the last month. The physicians spent 2.1 minutes on average (2.0 minutes for dermatologists) for patient education on proper use of topical steroids. The majority (79.1%) of physicians informed patients of the fact that the prescription contained steroids, while some were reluctant to disclose this information because of the negative perception about steroids in the general population.
Conclusion
This survey provides thorough information on the current status of prescription, counseling condition, doctors’ perception of patients’ knowledge of adverse events, and proper use of topical steroids.

OBJECTIVE: The purpose of this study was to compare the kinematic and kinetic parameters in sit-to-stand (STS) movement between healthy elderly and young people. METHOD: We measured the maximal isometric hip and knee extension moment of the ten healthy young volunteers and ten elderly and analyzed the STS movement using a motion analyzer. The differences of temporal, kinematic, and kinetic variables between young and elderly were assessed. RESULTS: The maximal knee isometric moment of elderly was lower than that of young. There were no differences in total duration and the range of motion of hip and knee during STS movement between young and elderly. Comparing the kinetic variables normalized by maximal isometric extension moment, maximal knee extension moment and knee work were significantly higher in elderly. There were no differences in maximal knee power and kinetic variables of hip between young and elderly. CONCLUSION: It was the marked difference of STS movement between young and elderly that maximal knee extension moment normalized by maximal isometric extension moment was higher in elderly. It was reasonable that this difference was due to the difference of maximal knee isometric torque.

The known causes of dysphagia following cervical spine surgery include pre-vertebral soft tissue swelling, decreased posterior pharyngeal movement, and impaired upper esophageal sphincter opening. Some studies have suggested that dysphagia is associated with movement of the cervical vertebrae during swallowing. In the present case, a 59-year-old man with a limited cervical range of motion due to ankylosing spondylitis slipped and fell, resulting in a C7 vertebral body fracture. He underwent anterior cervical discectomy as well as C5-T1 anterior fusion and C5-T2 level postero-lateral fusion. After surgery, he showed signs and symptoms of aspiration. A video-fluoroscopic swallowing study (VFSS) revealed incomplete laryngeal elevation, cricopharyngeal dysfunction, and vallecular remnant. Aspiration was observed in the semisolid-swallowing test. The patient's dysphagia could be attributed to two main causes. First, the esophagus might have been compressed by thickened pre-vertebral soft tissue after surgery. Second, the cervical range of motion, which was already limited by ankylosing spondylitis, might have been limited further by the anterior fusion of the cervical spine. In conclusion, a preoperative evaluation, including VFSS, should be considered before cervical spinal surgery, particularly in patients with ankylosing spondylitis presenting with a limited cervical range of motion.
