ABSTRACT

BACKGROUND: Pneumonia is a common cause of illness and death of the elderly in Japan. Its prevalence is escalating globally with the aging of population. To describe the latest trends in pneumonia hospitalizations, especially aspiration pneumonia (AP) cases, we assessed the clinical records of pneumonia patients admitted to core acute care hospitals in Miyagi prefecture, Japan. METHODS: A retrospective multi-institutional joint research was conducted for hospitalized pneumonia patients aged ≥20 years from January 2019 to December 2019. Clinical data of patients were collected from the medical records of eight acute care hospitals. RESULTS: Out of the 1,800 patients included in this study, 79% of the hospitalized pneumonia patients were aged above 70 years. The most common age group was in the 80s. The ratio of AP to total pneumonia cases increased with age, and 692 out of 1,800 patients had AP. In univariate analysis, these patients had significantly older ages, lower body mass index (BMI), a lower ratio of normal diet intake and homestay before hospitalization, along with more AP recurrences and comorbidities. During hospitalization, AP patients had extended fasting periods, more swallowing assessments and interventions, longer hospitalization, and higher in-hospital mortality rate than non-AP patients. A total of 7% and 2% AP patients underwent video endoscopy and video fluorography respectively. In multivariate analysis, lower BMI, lower C-reactive protein, a lower ratio of homestay before hospitalization, a higher complication rate of cerebrovascular disease, dementia, and neuromuscular disease were noted as a characteristic of AP patients. Swallowing interventions were performed for 51% of the AP patients who had been hospitalized for more than two weeks. In univariate analysis, swallowing intervention improved in-hospital mortality. Lower AP recurrence before hospitalization and a lower ratio of homestay before hospitalization were indicated as characteristics of AP patients of the swallowing intervention group from multivariate analysis. Change in dietary pattern from normal to modified diet was observed more frequently in the swallowing intervention group. CONCLUSION: AP accounts for 38.4% of all pneumonia cases in acute care hospitals in Northern Japan. The use of swallowing evaluations and interventions, which may reduce the risk of dysphagia and may associate with lowering mortality in AP patients, is still not widespread.

ABSTRACT

A 49-year-old Japanese man presented with a rare case of sinonasal leiomyosarcoma with left nasal bleeding for 12 months. He had no history of irradiation or malignancies, including retinoblastoma. Preoperative histological examination suggested vascular leiomyoma. Complete resection with endoscopic surgery was performed. Histological examination during the operation suggested that the tumor was a leiomyoma. However, immunohistochemical staining for α smooth muscle actin and desmin were helpful in establishing a definitive diagnosis of sinonasal leiomyosarcoma. The resection margins were positive for tumor cells. Staging with CT of the neck and thorax, ultrasound of the abdomen, and MRI of the head ruled out metastases. Second endoscopic tumor resection surgery was performed for positive resection margins. The patient's condition was successfully managed with additional excision, and he remains well with no evidence of recurrence and metastasis 36 months after treatment. Endoscopic management should be considered in suitable cases.

ABSTRACT

<b>Introduction:</b> Recurrent thyroglossal duct cyst after surgery is not a rare condition and first-line treatment has not been established yet.<br/><br/> <b>Aim:</b> Evaluation of outcomes and complications of OK-432 treatment in patients with recurrent thyroglossal duct cyst after surgery. <br/><br/> <b>Material and methods:</b> This study is designed as a case series with planned data collection at Tohoku Medical and Pharmaceutical University and Fukase Clinic. Five patients with recurrent thyroglossal duct cyst after surgery received this therapy between January 2014 and February 2020 on an outpatient basis, without hospitalization. OK-432 solution was injected into the lesion using an 18- or 27-gauge needle, depending on the location and size of the lesion, as well as on possible complications.<br/> <br/> <b>Results:</b> Lesions showed marked reduction or total shrinkage in all patients, with no local scarring or deformity at the injection site. Side effects manifested as local pain at the site of injection and fever (37.5-38.5°C) observed in three patients, but the symptoms resolved within a few days.<br/> <br/> <b>Conclusions:</b> Since OK-432 therapy is simple, easy, safe and effective, it can be used as an alternative to surgery in the treatment of recurrent thyroglossal duct cyst after surgery.

ABSTRACT

A 79-year-old Japanese woman presented with a rare case of metastatic renal cell carcinoma to the left sphenoid sinus with left nasal bleeding. She had previously had right radical nephrectomy for renal cell carcinoma at the age of 64 years and brain and spinal cord infarction at 74 years. Endoscopic examination revealed no mass in the nasal cavity. CT and MRI revealed a tumor in the left sphenoid sinus. The size of the tumor increased gradually from 12 to 15 years after the radical nephrectomy. Complete resection with endoscopic surgery was performed without preoperative embolization. The tumor cells had clear cytoplasm and were arranged in a trabecular pattern lined by a layer of endothelial cells. These findings were identical to the pathological findings of the surgical specimen of the renal cell carcinoma from 15 years previous. A pathological diagnosis of metastatic renal cell carcinoma of clear cell type (grade 1) was made. PET-CT demonstrated no metastasis. The patient's condition was successfully managed with excision of the tumor, and she remains well with no evidence of recurrence and metastasis 36 months after treatment. Metastatic renal cell carcinoma to the sphenoid sinus is rare, but it might be considered in the differential diagnosis of masses in the paranasal sinus even long after initial treatment of renal cancer.
