[Curative Resection of Sigmoid Colon Cancer with Multiple Liver Metastases by Long-Term Multidisciplinary Treatment].

A male patient in his 80s underwent colonic stenting for obstructive sigmoid colon cancer with multiple liver metastases. With systemic chemotherapy for approximately 1 year, the liver metastasis disappeared, so laparoscopic sigmoid colectomy was performed for the primary lesion. No recurrence was observed for a while, although CT revealed liver metastasis in the liver S4, and radiofrequency ablation was performed. Radiation therapy was performed for the liver metastasis of liver S2 that subsequently appeared. After a recurrence-free period of approximately 2 years, a rapid regrowth of liver metastasis in liver S2 was observed. Thus, 4 years and 3 months after the initial diagnosis, lateral segmentectomy of the liver was performed. Five years have passed since the first visit, and he is alive without recurrence. The patient had obstructive colorectal cancer with unresectable liver metastasis, and as the obstruction was released by a colonic stent, systemic chemotherapy was prioritized. Hence, liver metastasis was controlled, and the primary lesion was resected. Furthermore, for the liver metastasis that appeared later, various loco-regional cancer therapies were provided to achieve a cancer-free state.

[Long-Term Survival by Low-Dose Imatinib after Recurrence of GIST].

A man in his 70s was observed to have GIST recurrence 19 months after surgery. Chemotherapy was initiated with imatinib 400 mg/day orally. The dose was eventually reduced to 100 mg/day to avoid side effects. Tumor reduction was confirmed 3 months after treatment initiation. Currently, 84 months after the onset of GIST, the patient survives with continuous intake of the same dose of oral imatinib. We were able to observe long-term survival in a patient with recurrent GIST after the administration of a small dose of imatinib.

Meningitis and Ventriculitis due to Nocardia araoensis Infection.

A 73-year-old man was admitted to our hospital with disturbance of consciousness, fever and headache. Cerebrospinal fluid (CSF) analysis revealed pleocytosis with neutrophil predominance, increased protein and low glucose. CSF and blood cultures yielded negative results. Antibiotics and antituberculous drugs were started for meningitis. An antimycotic was also added. The patient died from transtentorial hernia 99 days after admission. Autopsy revealed meningitis, ventriculitis and brain abscess, and Nocardia araoensis was detected in pus from the left lateral ventricle. This appears to represent the first report of N. araoensis meningitis complicated by ventriculitis and brain abscess.

Stroke education for multidisciplinary medical personnel in a rural area of Japan for promotion of hospital visit of acute stroke patients.

BACKGROUND: There are few studies of stroke education suitable for multidisciplinary medical personnel. A reorganization of the management of acute stroke and stroke education for multidisciplinary medical personnel started since 2013 in our hospital located in a rural area of Japan. This study aimed to examine the effect of our stroke education on changing the number of visits of acute stroke patients to our hospital and to test the stroke knowledge of medical personnel. METHODS: The stroke education, composed of a 20-minute lecture, was given by a stroke neurologist to 217 medical personnel (age, 49 ± 10 years; male, 70%). Posters printed with the FAST message were given to the participants at the end of the lesson: F, facial drooping; A, arm numbness or weakness; S, slurred speech or difficulty speaking or understanding; T, a time to call an ambulance. Participants completed questionnaires on stroke knowledge at baseline and 3 months after the lesson. RESULTS: The number of participants who remembered correctly the FAST mnemonic at 3 months was significantly higher than at baseline (78 vs. 90%, P = .006). The correct answer rate for stroke symptoms other than FAST such as vision loss was approximately 50% at 3 months. The number of visits of acute stroke patients to our hospital, particularly patients with transient ischemic attack, increased significantly compared with that before the stroke education. CONCLUSIONS: Our stroke education method using the FAST mnemonic designed for multidisciplinary medical personnel improved their stroke knowledge. Reorganization of the management of acute stroke and greater stroke knowledge for medical staff are necessary to increase the visits of acute stroke patients in the rural areas.

Skull metastasis from clear cell chondrosarcoma.

A 67-year-old man presented with left lower cranial nerve paresis and dysfunction of the left cerebellar hemisphere 4 years after amputation of the left lower leg because of clear cell chondrosarcoma (CCC). Neuroimaging studies showed an osteolytic extradural mass with homogeneous enhancement in the left posterior fossa. Bone scintigraphy disclosed a single high-uptake lesion at the same site. The tumor was removed totally via a left suboccipital craniotomy. Histological examination found mainly clear cells arranged in a microlobular pattern separated by thin fibrovascular stroma. The nuclei were regular with few mitotic figures. Immunohistochemical staining showed the tumor cells reacted intensely for both S-100 protein and vimentin. Osteoclast-like multinucleated giant cells were found at the periphery of the lobules. The primary tumor showed the same findings and the metastatic tumor manifested no malignant change. The histological diagnosis was metastatic CCC. CCC is a very rare neoplasm with slow growth and low-grade malignancy. Distant metastasis is rare but can occur in the skull base bone despite radical resection of the primary tumor. Osteolytic findings of homogeneous enhancement on magnetic resonance imaging and a high uptake on bone scintigraphy are indicative of metastatic tumor from previous CCC.
