Purpose: Pusher syndrome in stroke patients is the tendency to push strongly toward the paretic side with the non-affected limbs. The purpose of this study was to estimated inter-rater and intra-rater reliability of the Scale for Contraversive Pushing (SCP). Methods: Fourteen patients in the acute phase after stroke onset were diagnosed with pusher syndrome. Two physical therapists randomly assessed the same patients on different occasions on the same day. Almost all patients were assessed on more than one day. The inter-rater and intra-rater reliability of the SCP was estimated by calculation of the intraclass correlation coefficient (ICC). Results: The intra-rater reliability of the SCP ranged from 0.87 to 0.97; the inter-rater reliability of the SCP ranged from 0.71 to 0.99 in sitting and standing positions. These results show good reliability for the calculated variables. Conclusion: The results provide support for the use of the SCP in assessing pusher syndrome based on its reliability in stroke patients. It may use the standardized clinical assessments in clinical implication.

The purpose of this research is to develop and validate an instrument that can be used to measure critical aspects of a parent's attitude and behavior that influence child development and adaptation. This instrument is named Parenting Style Inventory and self-reporting assessment of parent for preschoolers. We reported findings from 578 preschooler's care-givers. Five factors were extracted from 55 items developed for preschooler version and finally 29 items were selected. Subscales were empathy, respect, parental authority, coerciveness, perfectionism. Internal consistency of these subscales were .77, .86, .70, .74, .68 relatively. Empathy, respect and authoritative scales were regarded as the basic dimensions of parent's behavior. For clinical validation, we divided the preschooler care-giver sample into 8 groups according to scores of the basic dimensions and compared the 8 groups with parenting stress and parenting self-efficacy scores. The results indicated that three basic factors would have different effects on parental experiences and satisfaction. We suggested the clinical implication and limitation of this instrument.

Background and Objectives: Determination of the lesion side based on the direction of the nystagmus could result in confusions to the clinicians due to mismatch between the vestibular function tests and also between vestibular and audiologic features. To minimize these mistakes, we elucidated the clinical manifestation and vestibular function test results in cases with recovery spontaneous nystagmus (rSN). Subjects and Methods: Patients who visited ENT clinic of tertiary referral hospital for acute onset continuous vertigo from January 2008 to December 2011 were enrolled. In these patients, we assessed onset time of vertigo, time point of paralytic spontaneous nystagmus (SN) and time point of rSN. At each time point of SN, vestibular function tests and hearing function tests were performed. Results: We confirmed the rSN among patients with unilateral vestibulopathy and demonstrated that high gain of the rotatory chair test (slow harmonic acceleration) and/or mismatch of the SN direction and contralateral caloric weakness could indicate the recovery state of patients and nystagmus observed in this stage is recovery phase nystagmus. Conclusions: In acute vestibulopathy patients, recovery phase nystagmus was observed and on this stage of disease vestibular function tests shows several features that could predict recovery state.

Background : The term "mononeuropathy multiplex" means simultaneous or sequential involvement of individual noncontiguous nerve trunks, evolving over days to years. The aim of this study was to delineate the causes, clinical features, and detailed electrophysiological findings in the patients with mononeuropathy multiplex. Methods : We analyzed the medical records of 22 patients with mononeuropathy multiplex confirmed on electrophysiological studies in Inje University Seoul Paik Hospital, Seoul Municipal Boramae Hospital, and Seoul National University Hospital between 1991 to 2000. Results : The number of male and female patients was equal. The mean age was 48 years with a peak incidence in the sixth decade. The etiology could be divided into vasculitis(11 patients) or non-vasculitis group. In vasculitis group, Churg-Strauss syndrome, polyarteritis nodosa, and rheumatoid arthritis were included. The non-vasculitis group included diabetes mellitus, leprosy, and Guillain-Barre syndrome. Ulnar and median nerves were most commonly involved(91%). In descending order of frequency, peroneal, posterior tibial, sural, and radial nerves were also involved. Bilateral involvement occurred most commonly in ulnar nerve. The symptoms and signs of mononeuropathy multiplex were the initial manifestations in 12 patients(55%), which was more frequent in vasculitis group(73%). Nerve conduction abnormalities could be divided into axonal, demyelinating, or mixed type. Most(91%) of the patients in vasculitis group revealed axonal type abnormalities. The location of the nerve lesion was frequently related to potential site of entrapment in demyelinating type. Conclusions : Mononeuropathy multiplex is the presenting features of the etiological disease frequently, especially in vasculitis group. Nerve conduction studies(NCS) reveals not only axonal type but also demyelinating type abnormalities. The etiological diseases were different in each type. Therefore, NCS is very helpful for the early etiological diagnosis and therapeutic implication in the patients with mononeuropathy multiplex.

Conjugation of the methyl group at the fifth carbon of cytosines within the palindromic dinucleotide 5'-CpG-3' sequence (DNA methylation) is the best studied epigenetic mechanism, which acts together with other epigenetic entities: histone modification, chromatin remodeling and microRNAs to shape the chromatin structure of DNA according to its functional state. The cancer genome is frequently characterized by hypermethylation of specific genes concurrently with an overall decrease in the level of 5-methyl cytosine, the pathological implication of which to the cancerous state has been well established. While the latest genome-wide technologies have been applied to classify and interpret the epigenetic layer of gene regulation in the physiological and disease states, the epigenetic testing has also been seriously explored in clinical practice for early detection, refining tumor staging and predicting disease recurrence. This critique reviews the latest research findings on the use of DNA methylation in cancer diagnosis, prognosis and staging/classification.

We report a patient who underwent gamma knife radiosurgery to treat recurrent meningioma after microsurgery and thereafter developed secondary malignancy adjacent to the original tumor. A 47-year-old woman had underwent resection of the olfactory groove meningioma. Then radiosurgery was done three times over 4 year period for the recurrent tumor. After 58 months from the initial radiosurgery, she presented with headache and progressive mental dullness. Huge tumor in bifrontal location was revealed in MRI. Subsequent operation and pathological examination confirmed diagnosis of glioblastoma. This case fits the criteria of radiation-induced tumor and the clinical implication of the issue is discussed.

Licorice has been wed in clinical medicine for thousands of years. However it is only in recent times that we have been able to employ scientific methods to prove its efficacy and to give us a better understanding of its mechanism of action. One of important mechanisms for its efficacy is related to mineralocorticoid activity increased by glycyrrhizic acid, the active ingredient in licorice. Also the main undesirable side-effects of Licorice relate to is mineralocorticoid activity resulting in a state of apparent mineralocorticoid excess (AME). These therapeutic and undesirable effects are explained by the inhibition of 11-$\beta$-hydroxysteroid dehydrogenase (11-$\beta$-HSD) activity. Recently, the reduction of serum testosterone in men by licorice was reported which would have important health implications in the context of fertility and sexual dysfunction. Here, health implication of licorice were reviewed In term of its pharmacodynamic and toxicodynamic mechanism.
