We report a case of spinal cord neurocytoma in a 67-year-old man who had experienced a progressive numbness of the left foot during the previous 4 years. Magnetic resonance imaging showed a well-defined intramedullary tumor located at the T10-T11 level. The pathological examination revealed histological characteristics described in neurocytomas. The tumor cells showed a uniform small nucleus and clear or slightly eosinophilic cytoplasm with frequent perinuclear halos, resembling the picture of oligodendroglioma. Some tumor cells exhibited mature ganglion cell appearance. Electron microscopy showed cells with microtubules and dense-core vesicles in their cytoplasm and cytoplasmic process. Immunohistochemically, the majority of tumor cells expressed synaptophysin and neuron-specific enolase. We conclude that this tumor is an exceptional case of neurocytoma located in the spinal cord, and consider that the term neurocytoma can be applied to tumors with neuronal differentiation intermediate between neuroblastoma and ganglioneuroma, even if arising in CNS outside of the intracranial ventricular system.

Posterior reversible encephalopathy syndrome (PRES) is a clinico-neuroradiologic disease entity represented by characteristic magnetic resonance image (MRI) findings of subcortical/cortical hyperintensity in T2-weighted sequences, more often observed in parieto-occipital lobes, accompanied by clinical neurologic alterations. PRES is a rare central nervous system complication in childhood hematologic-oncologic patients and shows very different neurologic symptoms between patients, from numbness on extremities to generalized seizure. The etiology of PRES was not well known until these days. In this study, 8 patients with PRES were reviewed, retrospectively. There were 4 patients with acute lymphocytic leukemia, 1 with aplastic anemia, and 3 with solid tumors (1 patient each for neuroblastoma, Ewing sarcoma, and osteosarcoma). Allogeneic stem cell transplantation was performed in 2 patients. Immunosuppressive agents such as tacrolimus and cyclosporine A were used in 3 patients. One neuroblastoma patient was in immediate postoperative status. All patients experienced seizure attacks of different types and showed typical MRI findings. Follow-up MRIs revealed significant improvements. From this review, we might consider chemotherapy and surgery as additive causes for PRES other than immunosuppressive agents. Therefore, careful examination of the patients receiving chemotherapy and surgery was needed to find out this uncommon but good prognostic complication.

The objective of this study was to evaluate the effectiveness of traditional herbal medicines (Kampo) on the symptoms of Yusho. Yusho is a mass food poisoning that was caused by ingestion of rice oil contaminated with dioxins and related organochlorines in 1968. Patients with Yusho suffer from skin symptoms (acneform eruptions, liability to suppuration and pigmentation), respiratory symptoms (cough and expectoration of sputum), neurological symptoms (numbness and paresthesia of extremities), arthralgia and general fatigue, and no effective treatment has yet been developed. In this clinical trial, four Kampo formulae (Bakumondo-to, Keigai-rengyo-to, Gosha-jinki-gan and Hochu-ekki-to) were administered to four representative Yusho symptoms (respiratory, skin, neurological symptoms and general fatigue), respectively. Twenty-seven Yusho patients were enrolled and two formulae were administered to each patient for half-a-year each. The effectiveness of Kampo formulae was estimated by changes in the intensity of symptoms measured by a visual analogue scale (VAS) of 100 mm recorded at baseline and after administration of each formula. The influence of Kampo formulae on patients' quality of life (QOL) was also assessed by the SF-36 (NBS). Twenty-five patients completed the treatment. Bakumondo-to significantly improved respiratory symptoms as well as patients' QOL in the context of vitality, compared with other formulae. In contrast, Hochu-ekki-to impaired patients' QOL in the context of physical functioning and vitality, compared with other formulae. This study demonstrated for the first time that a Kampo formula Bakumondo-to is useful for treating respiratory symptoms caused by dioxins.

We report a 53-year-old male patient who underwent paravertebral mass excision at the D10-11-12 vertebral levels in 2007. The histopathological evaluation of the mass showed the presence of neuroblastoma. The patient was diagnosed with stage IV neuroblastoma. He received 6 courses of chemotherapy and exhibited a stable course until March 2010. When he was reevaluated in March 2010, progression in the metastatic lesion as well as local recurrence was detected. The patient, who was restarted on chemotherapy, developed progressive weakness and loss of sensation of the lower extremity. The neurosurgical investigation revealed an irreversible loss in motor functions. The patient is currently on symptomatic treatment.

Vincristine (VCR), an alkaloid extracted from vinca, is often used in combination with other chemotherapeutic drugs to treat a variety of cancers, such as acute lymphoblastic leukaemia (ALL), malignant lymphoma, and neuroblastoma. However, VCR possesses dose-dependent neurotoxicity, which is the main factor restricting its application. Vincristine-induced peripheral neuropathy (VIPN) not only limits the dose of VCR and leads to the discontinuation of treatment but also triggers serious damage to the physical and mental health of patients. In addition, VIPN brings huge healthcare costs to patients and society. Individuals with VIPN often exhibit mechanical allodynia, sensory/tactile disorders, and numbness in the hands and feet. Unfortunately, VIPN is easily ignored due to its variable symptoms, which gives rise to insufficient research on the aetiology and pathogenesis of this disease, thereby resulting in a lack of appropriate preventive and therapeutic management. We performed a comprehensive review of the latest findings on VIPN in terms of symptoms, risk factors, potential mechanisms, and prevention and treatment measures. The purpose was to help clinicians better understand and accurately diagnose VIPN, select appropriate intervention measures and reduce the damage to cancer patients.
