Retrospective Analysis of Idiopathic Granulomatous Mastitis: Its Diagnosis and Treatment

PURPOSE: Idiopathic granulomatous mastitis (IGM) is a rare disease characterized by noncaseating granulomatous inflammation of unknown origin. Because its clinical features are similar to those of other type of mastitis or breast cancer, accurate diagnosis and adequate treatment are essential to ensuring a short symptom duration and improving the quality of life. METHODS: The clinical, radiologic, pathophysiologic, and treatment data for 43 patients diagnosed with IGM at the Breast Cancer Center of Gachon University Gil Medical Center between 2005 and 2016 were retrospectively reviewed. RESULTS: Forty-one patients (95.34%) were of childbearing age, seven (16.27%) had a history of lactation, and five (11.62%) had a history of oral contraceptive use. In terms of radiologic findings, 30 patients (69.77%) were diagnosed with Breast Imaging-Reporting and Data System category ≥4A lesions. Corticosteroid therapy was administered to 36 patients (83.72%); overall, 18 patients (41.86%) did not require surgery and 25 patients (58.13%) underwent partial or total mastectomy. Twelve patients (27.90%) developed recurrence. CONCLUSION: IGM is a benign disease that can be misdiagnosed as breast cancer because of its similar clinical and radiologic findings. Proper diagnosis and treatment can be difficult, but delays may lead to prolonged pain and cosmetic and socioeconomic problems. Efforts should be aimed at establishing the cause of IGM and developing efficient protocols for its diagnosis and treatment.

Satisfaction, and Factors Influencing Satisfaction, with Internal Environment and Safety of Emergency Medical Service Ambulances in Korea: Pilot Study of Patients and Guardians

PURPOSE: This study was conducted to assess the satisfaction, and factors influencing the satisfaction, of patients and guardians with the internal environment and safety of ambulances in Korea. METHODS: Participants were patients and guardians who were transported by public emergency medical service ambulance to an emergency medical center in June 2015. Data were collected using self-administered questionnaires. The degree of satisfaction with the ambulance was categorized as satisfaction (Likert scale 4 or 5) or dissatisfaction (Likert scale 1 or 2). The questionnaires comprised 3 categories: 1) demographics, 2) internal environment (space, light, temperature, humidity, soundproof, and odor), and 3) safety (vibration, leaning of body, and falling objects). RESULTS: Among 84 cases, 80.5% of patients and 83.7% of guardians gave positive responses regarding general satisfaction with the internal environment of the ambulance, but these percentages were lower regarding adequacy of space and light. Four factors had a statistically significantly influence on the degree of satisfaction: 1) sex of guardian regarding adequacy of space, 2) number of guardians regarding general satisfaction, 3) severity of patient regarding guardian's satisfaction with space, 4) diagnosis of patient (trauma vs non-trauma) regarding vibration during transport (all p<0.05). CONCLUSION: Overall, patients and guardians were satisfied with the internal environment and safety of ambulances except for adequacy of space and light.

The effect of long-term oral dantrolene on the neuromuscular action of rocuronium: a case report / 대한마취과학회지

Oral dantrolene causes a dose-dependent depression of skeletal muscle contractility. A 52-year-old man treated with oral dantrolene for spasticity after spinal cord injury was scheduled to undergo irrigation and drainage of a thigh abscess under general anesthesia. He had taken 50 mg oral dantrolene per day for 3 years. Under standard neuromuscular monitoring, anesthesia was performed with propofol, rocuronium, and sevoflurane. A bolus dose of ED95 (0.3 mg/kg) of rocuronium could not depress T1 up to 95%. An additional dose of rocuronium depressed T1 completely and decreased the train-of-four (TOF) count to zero. There was no apparent prolongation of the neuromuscular blocking action of rocuronium. The TOF ratio was recovered to more than 0.9 within 40 minutes after the last dose of rocuronium. A small dose of oral dantrolene does not prolong the duration of action and recovery of rocuronium.
