There is a lack of evidence and consensus in terms of the association between dietary intake of sodium (Na) and potassium (K) with mental health. By using 24-hours urinary samples as the gold standard method, we conducted a study to explore the association between dietary intake of Na and K with parameters of mental health including depression, anxiety, and stress among an Iranian population diagnosed with migraine. In the present study, 262 subjects (20-50 years old), with a confirmed diagnosis of migraine were enrolled. Mental health was investigated by the Depression, Anxiety, and Stress Scales (DASS-21) questionnaire. Dietary intake of Na and K was estimated by means of a 24-hour urine sample. Multinomial logistic regression analysis was implemented and odds ratio (OR) with 95% confidence interval (CI) was stated. After controlling for potential confounders, the 24-hour urinary Na was associated significantly with the risk of depression (OR = 0.55, 95% CI: 0.30, 1.00; P = .053). After adjustment for confounders, those in the highest tertile of the 24-hour urinary Na/K ratio had lower odds for having depression (OR = 0.54, 95% CI: 0.31, 0.93; P = .027), and marginally significantly lower risk of anxiety (OR = 0.58, 95% CI: 0.31, 1.06; P = .079) and stress (OR = 0.56, 95% CI: 0.31, 1.02; P = .061). In conclusion, higher 24-hour urine Na was associated with a significantly lower risk of depression. Moreover, the 24-hour Na/K ratio was significantly associated with lower risk of depression, anxiety, and stress.

The traditional diagnosis model has great challenges for the etiological diagnosis of the central nervous system (CNS) diseases with similar clinical manifestations, especially for the diagnosis of rare pathogens. It is very important to make rapid and accurate identification of pathogens for guiding clinical choices in administering countermeasures.

To evaluate the efficacy and safety of dexamethasone (DEXA) combined with tranexamic acid (TXA) in the perioperative period of total hip arthroplasty.

A 75-year-old man presented with headache and disturbance of consciousness. Magnetic resonance imaging revealed edema localized mainly in the cortex and linear contrast enhancement. A brain biopsy revealed numerous astrocytes with inclusion, and genetic testing demonstrated prolonged GGC repeats in NOTCH2NLC. The present case provided two novel insights into the mechanism underlying encephalopathy associated with neuronal intranuclear inclusion disease. First, the histological findings at a site with contrast enhancement on magnetic resonance imaging did not demonstrate any organic association, such as the presence of inflammation or ischemic changes. Second, the imaging and cerebrospinal fluid findings demonstrated increased cerebral blood flow and opening of the blood-brain barrier, indicating the cause of the cerebral swelling.

A 41-year-old man visited our clinic because of headache with fever, suggestive of aseptic meningitis. His headache improved in a few days. His neurological examination showed positive jolt accentuation and myoclonus of the thoracoabdominal muscles extending to extremities upon patellar tapping. His myoclonus had been occurring spontaneously from early adolescence, especially in relaxed states such as drowsiness. The myoclonus was not triggered by tactile, auditory, or visual stimulation. Polymyography revealed that the myoclonus originated around the T4 spinal level and slowly propagated both upward and downward. These findings were indicative of spontaneous and reflex propriospinal myoclonus (PSM). No abnormalities were seen on brain and spinal MRI. Furthermore, the amplitude of the cortical component of the somatosensory evoked potential (SEP) after electrical stimulation of the tibial nerve was enlarged bilaterally. It was speculated that the ascending signals from the myoclonus generator at T4 to S1 may have modulated the excitability and inhibitory function of S1 in this patient. This report may be the first case of idiopathic PSM accompanied by giant SEP.
