RESUMO
Pyomyositis is classified into two main types: tropical and non-tropical. Non-tropical pyomyositis occurs among various immunocompromised patients, and Staphylococcus aureus has been reported as the most common pathogen. Pyomyositis caused by Streptococcus pneumoniae is uncommon, and has not been previously reported after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Here, we report a unique case with pyomyositis caused by S. pneumoniae in the bilateral erector spinae muscles 34 months after allo-HSCT. The patient had an initial clinical response following the administration of intravenous benzylpenicillin potassium for 4 weeks. Although S. pneumoniae bacteremia is a rare bacterial infection after HSCT, the possibility of pyomyositis must be considered when a recipient develops S. pneumoniae bacteremia. Accurate diagnosis and the selection of appropriate antibiotics are necessary for the treatment of pyomyositis.

Stereotactic body radiotherapy (SBRT) has excellent local control and low toxicity for spinal metastases and is widely performed for spinal oligometastases. However, its additional survival benefit to standard of care, including systemic therapy, is unknown because the results of large-scale randomized controlled trials regarding SBRT for oligometastases have not been reported. Consequently, the optimal patient population among those with spinal oligometastases and the optimal methodology for spine SBRT remain unclear. The present review article discusses two topics: evidence-based optimal patient selection and methodology. The following have been reported to be good prognostic factors: young age, good performance status, slow-growing disease with a long disease-free interval, minimal disease burden, and mild fluorodeoxyglucose accumulation in positron emission tomography. In addition, we proposed four measures as the optimal SBRT method for achieving excellent local control: (i) required target delineation; (ii) recommended dose fraction schedule (20 or 24 Gy in a single fraction for spinal oligometastases and 35 Gy in five fractions for lesions located near the spinal cord); (iii) optimizing dose distribution for the target; (iv) dose constraint options for the spinal cord.

A man in his 40s who had made frequent visits abroad was admitted to our hospital complaining of epigastric pain. Ultrasonography (US) revealed an "inner tube sign" in the gallbladder, which suggested a diagnosis of ascariasis in the gallbladder. Pyrantel pamoate was directly injected into the gallbladder via a percutaneous transhepatic catheter. The worm was dead 10 minutes after the injection. US revealed reduction of the worm's length and then the disappearance of the worm from the gallbladder at both 13 days and 2 months after the injection. This method is less invasive than operation and therefore is possibly more safe. It is known that the number of cases of ascariasis may increase in Japan due to increased organic vegetable consumption and foreign travel. We need to consider this disease in the differential diagnosis of epigastric pain.
