Severe fibromyalgia alleviated by the unique muscle relaxation method of applying low force: A case report.

RATIONALE: Fibromyalgia (FM) is characterized by idiopathic persistent chronic pain in the ligaments or musculoskeletal system, and more than half of the patients with FM might have migraine headaches. Direct musculoskeletal intervention could be a non-pharmacological management to relieve symptoms. However, patients with severe FM often have intense pain from only a soft touch, thereby rendering musculoskeletal intervention challenging. PATIENT CONCERNS: A 47-year-old man had progressing intense pain, and this affected his everyday life. There were no abnormal physical findings on laboratory examination such as levels of complement, antinuclear antibodies, and C-reactive protein, which were within normal limits. Magnetic resonance imaging did not indicate abnormalities. DIAGNOSES, INTERVENTIONS, AND OUTCOMES: The patient satisfied the American College of Rheumatology criteria. Finally, we made a final diagnosis of fibromyalgia. The therapeutic intervention of Kanshoho, the unique muscle relaxation technique with low force, relieved his pain. LESSONS: If Kanshoho is carefully applied in a state of hospitalization under surveillance by an experienced physician, it could be a promising muscle relaxation method. Relaxing the trapezius muscle and reducing its intramuscular pressure might be key in treating patients with severe FM. However, it needs elucidation of its mechanism.

Unpredictable refeeding syndrome with severe hypophosphatemia in borderline personality disorder comorbidity: A case report.

RATIONALE: Refeeding syndrome (RS) is a fatal condition caused by rapid calorie intake during starvation. Self-neglected fasting in psychiatric disorders is associated with RS. However, overeating resulting from circumventing the clinician's instructions does not have a reportedly high risk of RS. PATIENT CONCERNS: A 47-year-old undernourished woman with borderline personality disorder was hospitalized for nausea, vomiting, and diarrhea. CLINICAL FINDINGS: She had not eaten much for 10 days and had lost weight (56.5-51.1 kg) over 3 weeks. No abnormalities were indicated on physical examination and imaging examinations. DIAGNOSES, INTERVENTIONS, AND OUTCOMES: Infectious diseases and malignancies were excluded from the differential diagnosis. On the third day of admission, the patient's serum phosphorus level significantly decreased to 0.7 mg/dL, and additional sodium phosphate was administered intravenously. On the fourth day, despite our instructions, the patient was found to be eating nonhospital food from the first day of admission. In conjunction with her history, a final diagnosis of RS was made. After appropriate treatments, the patient was discharged on the 15th day of hospitalization. The patient's nausea, vomiting, and diarrhea were improved. LESSONS: When undernourished patients have psychiatric disorders, including borderline personality disorder or schizophrenia, the occurrence of RS should be considered based on the patients' poor adherence to physicians' instructions.

Lavender Oil Reduces Depressive Mood in Healthy Individuals and Enhances the Activity of Single Oxytocin Neurons of the Hypothalamus Isolated from Mice: A Preliminary Study.

BACKGROUND: The aim of the present study was to assess the effects of lavender oil inhalation on blood pressure, pulse measurements, cortisol levels, depressive mood, and anxiety in healthy male adults. The mechanism was investigated by the action on oxytocin single neurons in the hypothalamus of rodents. METHODS: The participants (n = 7) were aged 20-40 years. After randomisation, they received an inhaled dose of lavender oil or distilled water for 20 min. They received the other treatment after a washout period of one week. We assessed the outcomes using the Self-Rating Depression Scale, State-Trait Anxiety Inventory, and self-rated unidimensional Visual Analogue Scale for depression; anxiety; and hunger, thirst, and appetite, respectively. Blood pressure, pulse rate, and cortisol concentration in the peripheral blood were assessed before and after inhalation. In the rodent study (n = 4), oxytocin single neurons were isolated from the mouse hypothalamus. Intracellular Ca2+ concentration in the oxytocin neurons isolated from the hypothalamus was measured following direct administration of lavender oil. RESULTS: Seven participants completed the study. Lavender inhalation decreased Self-Rating Depression Scale score and systolic and diastolic blood pressure. Ex vivo administration of lavender oil increased intracellular Ca2+ concentration in the hypothalamic oxytocin neurons. CONCLUSIONS: Lavender oil might be a useful therapy for stress relief, and its mechanism of action may include activation of the central oxytocin neurons.
