Object. Spinal subdural hematomas (SDHs) are rare and some are concomitant with intracranial SDH. Their pathogenesis and etiology remain to be elucidated although their migration from the intracranial space has been suggested. The authors postulated that if migration plays a major role, patients with intracranial SDH may harbor asymptomatic lumbar SDH. The authors performed a prospective study on the incidence of spinal SDH in patients with intracranial SDH to determine whether migration is a key factor in their concomitance. Methods. The authors evaluated lumbar MR images obtained in 168 patients (125 males, 43 females, mean age 75.6 years) with intracranial chronic SDH to identify cases of concomitant lumbar SDH. In all cases, the lumbar MRI studies were performed within the 1st week after surgical irrigation of the intracranial SDH. Results. Of the 168 patients, 2 (1.2%) harbored a concomitant lumbar SDH; both had a history of trauma to both the head and the hip and/or lumbar area. One was an 83-year-old man with prostate cancer and myelodysplastic syndrome who suffered trauma to his head and lumbar area in a fall from his bed. The other was a 70-year-old man who had hit his head and lumbar area in a fall. Neither patient manifested neurological deficits and their hematomas disappeared under observation. None of the patients with concomitant lumbar SDH had sustained head trauma only, indicating that trauma to the hip or lumbar region is significantly related to the concomitance of SDH (p < 0.05). Conclusions. As the incidence of concomitant lumbar and intracranial chronic SDH is rare and both patients in this study had sustained a direct impact to the head and hips, the authors suggest that the major mechanism underlying their concomitant SDH was double trauma. Another possible explanation is hemorrhagic diathesis and low CSF syndrome. ©AANS, 2014. Source

A 70-year-old male, who had undergone resection of gastric malignant lymphoma in 1992, presented with cervical lymph node swelling in January 2008. Pathological examination of the lymph node biopsy demonstrated recurrence of malignant lymphoma, and he was treated with the R-CHOP regimen. Although he did not develop fever during the first through third course of R-CHOP, from the fourth course, he repeatedly demonstrated fever over 38°C for about one week after each course of chemotherapy, despite the absence of neutropenia. Helicobacter cinaedi infection was confirmed by blood culture each time. Although it is difficult to diagnose Helicobacter cinaedi infection by the standard culture method, increased numbers of recent reports especially in immunocompromised patients have emphasized the importance of diagnosing Helicobacter cinaedi infection.

A 45-year-old HIV positive male who had previously been administered anti-retrovirus therapy (ART) resulting in a good virological response and with a CD4 count of more than 1,000/μl, complained of general fatigue during a periodic examination. Laboratory data showed decreased Hb (10.8 g/dl) and increased T.P (12.0 g/dl) and IgG (9,077 mg/dl). Monoclonal gammopathy (IgG-λ) was identified and bone marrow aspiration revealed 37.6% atypical plasma cells, leading to the diagnosis of symptomatic multiple myeloma (MM) (ISS clinical staging III).Four courses of VD (bortezomib+dexamethasone) therapy were administered with concurrent ART resulting in VGPR (very good partial response), followed by peripheral blood stem cell collection (the mobilizing chemotherapy was cyclophosphamide). Then, together with ART, high-dose chemotherapy (Mel-200; L-PAM) was administered with autologous peripheral blood stem cell transplantation (PBSCT). Reconstitution of white blood cells was achieved at 10 days after PBSCT. There were no adverse effects of ART and the viral load of HIV was well controlled during the period of these treatments. The final assessment was VGPR and 10 mg/day of lenalidomide has since been administered as maintenance therapy. Standard treatment combined with PBSCT for juvenile-onset MM is also effective and safe for HIV-positive patients receiving ART. Source

The authors describe a case of 28-year-old man who presented with cervical myelopathy and lumbar radiculopathy due to the giant cervical pseudomeningocele extending to the lumbar spine at 10 years after previous brachial plexus injury. To evaluate the communicating tract between pseudomeningocele and subarachnoidal space, the multidetector-row helical CT with simultaneous myelography was performed preoperatively. The surgical treatment in the cervical spine included the resection of pseudomeningocele and the repair of dural defects communicating into the cyst following multi-level laminoplasty and foraminotomies. At 6 years after surgery, the significant neurologic recovery and complete obliteration of cysts in the whole spine area were maintained. This serves as the first report describing the significant neurologic recovery after the surgical treatment of giant cervical pseudomeningocele extending to the lumbar spine after previous brachial plexus injury. © Springer-Verlag 2010.

Objective Neuromyelitis optica (NMO) is an inflammatory disease that affects the optic nerve and spinal cord. Optic neuritis and longitudinally extensive myelitis associated with systemic autoimmune disease have been recently defined as NMO spectrum disorder (NMOSD). In this study, we report the efficacy of intravenous cyclophosphamide (IVCY) therapy for NMOSD. Methods Four patients diagnosed with NMOSD were enrolled in this study. The expanded disability status scale (EDSS) score was used to evaluate the degree of severity. All of the patients received intravenous methylprednisolone (IVMP; 1 g/day for three days), and two patients also received plasmapheresis (PP). All of the patients were administered IVCY treatment. Results Anti-AQP4 antibodies were present in the sera of all patients. All patients exhibited longitudinally extensive transverse myelitis (LETM). Only one patient who fulfilled the criteria for a diagnosis of NMO exhibited optic neuritis. Two patients developed relapse under treatment with low-dose prednisolone (PSL) before the administration of IVCY. The patients in this study exhibited a median improvement in the EDSS score following IVCY treatment from 8.0 to 5. 75. Adverse effects were observed in only one patient. Conclusion This study, despite its retrospective design, demonstrated the therapeutic efficacy of IVCY for NMOSD in both the acute and chronic phases of the disease and determined the IVCY dosage for Japanese women with NMOSD. Additionally, this study provided evidence that for NMOSD patients with severe disabilities, IVCY added to IVMP and PP may be a useful therapeutic modality. © 2013 The Japanese Society of Internal Medicine.
