We report a case of actinomycosis arising in the minor salivary gland in the buccal region. A 71-year-old male presented with a swelling in the left buccal region. The clinical diagnosis was minor salivary gland tumor in the buccal mucosa. Under local anesthesia, the lesion was excised. Histopathological examination showed basophilic amorphous masses of Actinomyces in the dilated excretory duct with squamous metaplasia. A final diagnosis of actinomycosis was made. Its portal of entry was thought to be a disruption of the mucosal barrier after trauma due to maladaptation of dentures. There was no sign of recurrence after the surgery.

Methods:
Adolescent athletes with spondylolysis, including those with symptoms of low back pain, were enrolled. The sporting activity of the patients was restricted, and a hard brace was attached to the spine. The BME range of interest was taken on T2-weighed fat-saturated MRI, and the signal intensity (SI) of the BME (SIedema) was measured. The contrast ratio (CR) between the SI of the BME and SI of the spinal cord (SIcord) was calculated per the following formulae: CRedema=(SIedema–SIcord)/(SIedema+SIcord). The CR of the normal pedicle was measured as a control per the following formulae: CRcontrol=(SIcontrol–SIcord)/(SIcontrol+SIcord).
Results:
The study enrolled 32 men and one woman; the mean patient age was 15.2 years (range, 12–18 years). The average CR of the edema and normal pedicle at the first visit was 0.506 (range, 0.097–0.804) and 0.137 (range, -0.741 to 0.572), respectively. The CR of the edema was significantly higher as compared to that of the normal pedicle (p<0.01). MRI that was performed 1 month after the first visit showed that the CR of the edema had decreased to 0.204 (range, -0.152 to 0.517). The CR of the edema 1 month thereafter was significantly lower than that at the first visit (p<0.01).
Conclusions
Quantitative assessment of BME using CR on MRI is useful in the evaluation of the healing process of spondylolysis.

PURPOSE: To evaluate whether hydrodistention with fulguration of Hunner lesions (HD/FUL) plus maintenance dimethyl sulfoxide (DMSO) therapy prolongs the recurrence-free time in patients with Hunner type interstitial cystitis (IC).METHODS: The study enrolled patients with Hunner type IC who required repeat HD/FUL due to recurrence of IC symptoms after the first HD/FUL at our institution. All patients received a second HD/FUL plus maintenance DMSO therapy. The maintenance DMSO therapy was performed every 2 weeks for a total of 8 instillations, and then once every 4 weeks thereafter. The recurrencefree time from HD/FUL to therapeutic failure was estimated using the Kaplan-Meier method. The recurrence-free time between the first HD/FUL and second HD/FUL plus maintenance DMSO therapy was statistically compared using the log-rank test.RESULTS: A total of 21 patients (mean age, 66.3±10.8 years) with Hunner type IC were evaluated. The recurrence-free time for the second HD/FUL plus maintenance DMSO therapy was significantly longer than that for the first HD/FUL (P<0.0001). The median recurrence-free time for the first HD/FUL was 10.1 months, while that for the second HD/FUL plus maintenance DMSO therapy has yet to be reached. The recurrence-free rate for the first HD/FUL was 81.0% at 6 months, 38.1% at 1 year, 9.5% at 2 years, and 4.8% at 3 years. In contrast, the rate for the second HD/FUL plus maintenance DMSO therapy was 100% at 6 months, 94.7% at 1 year, 82.6% at 2 years, and 82.6% at 3 years. There were no significant differences in efficacy between the first and second HD/FUL.CONCLUSIONS: HD/FUL plus maintenance DMSO therapy clearly prolongs the recurrence-free time compared with HD/FUL alone in Hunner type IC.

Methods:
Patients with degenerative lumbar diseases, whose MRIs detected BME, were enrolled. On a T2-weighted fat-saturated MRI, BME appeared as a high-intensity region adjacent to the vertebral endplate. We calculated the contrast ratios (CRs) of BME and normal bone marrow using the signal intensities of BME, normal bone marrow, and the spinal cord. On computed tomography, we calculated Hounsfield unit (HU) values in the same area as BME, the sclerotic endplate, and normal bone marrow to assess bone density.
Results:
There were 16 men and 14 women, with an average age of 73.5 years. The mean CRs of BME and normal bone marrow were −0.015±0.056 and −0.407±0.023, respectively. BME’s CR was significantly higher than that of normal bone marrow (p<0.01). The HU values in the same area as BME, the sclerotic endplate, and normal bone marrow were 251.9±24.6, 828.3±35.6, and 98.1±9.3, respectively; these values were significantly different from each other (p<0.01).
Conclusions
The CR on MRI is a useful quantitative assessment tool for BME in patients with degenerative lumbar diseases.

This study investigated the characteristics of emergency patients, including walk-in patients and those brought in by ambulance, who visited Akita Kousei Medical Center in the 6 months from April 2019, and the clinical features of elderly patients with heart failure. Elderly patients above 70 years of age accounted for 38.7% of emergency cases and up to 61.7% of ambulance cases. The most common diseases and disorders were orthopedic, digestive, otorhinolaryngeal, respiratory, neurological, dermatological, and cardiovascular disease, in that order. In total, 56 patients with heart failure were admitted during this period (age 83.5±8.3 years, male: female ratio, 1:1.67). Hospitalization from homes accounted for 66.1% of admissions, with the remainder from nursing homes. After treatment, 35.7% of patients moved to nursing homes and 19.6% died despite in-hospital care. Because heart failure is one of the most common conditions in elderly patients, it is pertinent to recognize the importance of quality of outpatient care to prevent hospitalization and also to preserve quality of life by focusing on alleviating overall pain and discomfort.
