We report a rare case of Hodgkin's disease in which intracranial involvement developed during the course of the patients illness. A 20-year-old man who had complained of lymph node swelling on the right neck was admitted to a hospital in December 1978. Lymph node biopsy revealed Hodgkin's disease, and he was treated by various series of chemotherapy and radiotherapy with unsatisfactory results. He was transferred to Yamanashi Medical College Hospital in June 1985. He was in a far-advanced state at the time, and palliative treatment was applied. In the middle of May 1986, he complained of headache, tinnitus, and sleeplessness. Vomiting and tremor were observed by the end of May 1986. Brain CT scan revealed a space occupying lesion in the right temporal region. Whole brain irradiation of 45 Gy was effective, and the lesion disappeared. However, his general condition deteriorated and he died in November 1986. Brain autopsy could not be performed.

Tinnitus is the perception of phantom sounds in the ears or in the head. Sound therapy techniques for tinnitus treatment have been proposed. In order to investigate mechanisms of tinnitus generation and the clinical effects of sound therapy from the viewpoint of neural engineering, we have proposed a computational model using a neural oscillator. In the present paper, we propose another model that is composed of model neurons described by simplified Hodgkin-Huxley equations. By computer simulation it was detected that this model also has a bistable state, i.e., a stable oscillatory state and a stable equilibrium (non-oscillatory) state coexist at a certain parameter region. It was also noticed that the oscillation can be inhibited by supplying constant or pulse train stimuli, which is hypothesized as an afferent signal that is employed as an acoustical signal for tinnitus treatment. By hypothesizing that the oscillation and the equilibrium correspond to generation and inhibition of tinnitus, respectively, these phenomena could explain the fact that the habituated human auditory system temporarily halts perception of tinnitus following sound therapy.

Tinnitus is a condition in which sounds heard in the ear or head without any external sound. There are many therapeutic approaches for tinnitus and sound therapy is one of the techniques for its treatment that have been proposed. In order to investigate mechanisms of tinnitus generation and the clinical effects of sound therapy from the viewpoint of neural engineering, we have proposed computational models with plasticity and inhibitory feedback using a neural oscillator or model neurons described by simplified Hodgkin-Huxley equations. By hypothesizing that the oscillation and the non-oscillatory state in the models correspond to generation and inhibition of tinnitus, respectively, we found out that the models could explain the fact that the habituated human auditory system temporarily halts perception of tinnitus following sound therapy. However, a simpler model without inhibitory feedback can exhibit the solutions that exist in the former models. In the present paper, outcomes of the neuronal network model, which is incorporated with inhibitory feedback, are compared with the model without inhibitory feedback. It was revealed that the former is superior since it has a larger parameter region in which the effects of sound therapy can be restored due to synaptic plasticity.

Intravascular large B cell lymphoma (IVLBCL) is a rare type of extranodal large B cell lymphoma in the lumina of small vessels. Low high-density lipoprotein cholesterol (HDL-C) is associated with sepsis, malignancy, and death. Recent evidence suggests an inverse relationship between HDL-C and non-Hodgkin lymphoma. We report the case of a 71-year-old female who presented with decreasing HDL-C for years prior to diagnosis of IVLBCL. The patient developed nonspecific symptoms, including dizziness, gait instability, fatigue, tinnitus, and weight loss. Although malignancy was high on the differential, no diagnosis was made antemortem. The diagnosis of disseminated intravascular large B cell lymphoma was made postmortem in multiple organ systems. The presentation of IVLBCL is nonspecific and misleading. To our knowledge this is the second known case report of low HDL-C preceding diagnosis of IVLBCL, but the first case documenting low HDL-C years prior to diagnosis.
