Posttraumatic growth levels of healthcare workers in two periods with different intensities of COVID-19 pandemic.

The COVID-19 pandemic threatens health-care workers' (HCW) mental health and well-being. Although traumatic life events may result in psychiatric disorders, occasionally they give rise to positive changes, such as post-traumatic growth. Accordingly, the present study evaluated the traumatic stress, anxiety, and depression levels of HCWs and their post-traumatic growth levels during the pandemic. In addition, the study aimed to assess the changes in psychological outcomes during the pandemic. For this aim, the data were collected in two different periods. The first data-collection period was between May and July 2020, and the second period started in November 2020 and ended in January 2021. The sociodemographic data form, Impact of Events Scale-Revised (IES-R), Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), and Post-traumatic Growth Inventory (PTGI) were used to collect data. Sixty-six HCWs participated in the study. No significant differences appeared between the baseline scores and 6-month follow-up in the depression, anxiety, and traumatic stress levels of HCWs. Furthermore, the PTGI scores decreased significantly over time. Although the change in the psychological distress scores was not statistically significant, the depression and post-traumatic stress scores increased over time. Previous research specified an inverse-parabolic relationship between traumatic stress and PTGI. Our results support previous research; as the exposure to the stressors continues, individual traumatic stress levels increase, psychiatric disorders become frequent, and affirmative changes (like post-traumatic growth) decline.

Preventive drugs restore visual evoked habituation and attention in migraineurs.

Visual system pathway dysfunction has been postulated in migraineurs. We wanted to investigate if any difference exists interictally in visual attention and visual evoked habituation of frequently attacked migraineurs compared to the healthy control group. The effects of 3-month prophylactic migraine treatment on these parameters were also assessed. The migraineurs at headache-free interval (n = 52) and age, sex-matched healthy controls (n = 35) were compared by habituation response to 10 blocks of repetitive pattern-reversal visual stimuli (each block consisted 100 responses). The amplitude changes of 5th and 10th blocks were further compared with that of block 1 to assess the response of habituation (i.e., decrease) or potentiation (i.e., increase). The level of sustained visual attention was assessed by Cancellation test. Migraineurs were randomized to three different preventive treatments: propranolol 40 mg tid, flunarizine 5 mg bid, or topiramate 50 mg bid. After 3 months of preventive treatment, migraineurs data were compared with their baseline values. The groups did not differ by sex and age. In electrophysiological studies, the habituation ability observed in the healthy group was not observed in migraineurs. However, it was restored 3 months after preventive treatment. In migraineurs, compared to their baseline values, the distorted visual attention parameters also improved after treatment. All drugs were effective. The loss of habituation ability and low visual attention performance in migraineurs can be restored by migraine preventive treatment. This electrophysiological study accompanied by neuropsychological test may aid an objective and quantitative assessment tool for understanding migraine pathophysiology.

An unusual case of subclinical peripheral neuropathy and cervical spondylosis in atopic myelitis.

Many cases of atopic myelitis have been reported in Japan; however very few were described in western countries. An 82-year-old woman with a past medical history of atopic dermatitis and asthma presented with progressive paresthesia (tingling) of both hands and tetraparesis. Before the onset of neurological symptoms, she complained of ichthyosis of both legs for 5 weeks. Magnetic resonance imaging demonstrated multisegmental degenerative arthritis, degenerative disc disease, and abnormal spinal cord signal intensity over several cervical segments, suggesting the diagnosis of myelitis. Total serum IgE level was elevated. Nerve conduction studies revealed asymmetric axonal sensorimotor neuropathy. The cerebrospinal fluid specimen showed lymphocytic pleocytosis and elevated protein level. Based on clinical, imaging, and laboratory findings, atopic myelitis was diagnosed. The diagnosis of atopic myelitis should be considered in myelopathy patients with history of atopy and elevated serum IgE levels.
