Recently, because of the development of MRI, it is becoming apparent that there are some cases of cerebellar vascular disorder in the posterior cranial fossa among cases of sudden onset of rotatory vertigo. We reported two cases of sudden onset of rotatory vertigo caused by cerebellar infarction in the territory of the posterior inferior cerebellar artery (PICA) due to cervical occlusive injuries.Case 1. A 48-year-old male sustained a slight whip lash injury and after ten hours, experienced rotatory vertigo and hoarseness. When he came to our hospital, we could only detect hoarseness. However, vascular disorder in the posterior cranial fossa was suggested by the interview. MRI revealed left cerebellar and medulla oblongata infarction.Case 2. A 29-year-old male felt rotatory vertigo and vomited after clicking his neck. Upon closer examination, pure rotatory spontaneous nystagmus, sensory disorder accompanied by sensory dissociation in his face and disability in standing and walking were found, suggesting vascular disorder in the posterior cranial fossa. MRI showed infarction in the left inferior cerebellar region, vermis and left lateral-dorsal medulla oblongata. A dissecting aneurysm in the vertebral artery was found on subsequent angiography.In the Japanese literature, we could find only nine reported cases of cerebellar vascular disorder in the posterior cranial fossa due to the cervical occlusive injuries, in addition to our two cases.The severity of injuries and the period until onset of diagnostic symptoms varied. Therefore, tracing cerebellar vascular disorders due to cervical occlusive injury required not only neurological and neuro-otological findings, but also attention to the history of the original injury and the development of subsequent symptoms. Without a careful interview, it is very difficult to correctly establish the cause of the disorder.

Purpose: This present study was aimed at evaluating the effects of our original teaching method called “Bang Bang, Hu, Kacha” on the learning efficiency. Methods: We invented this method, which involves hand modulation and vocalization of words, for medical students to enable them to easily understand and memorize the anatomy of the inner ear and vestibular organs. We evaluated its effectiveness based on self-completed questionnaires by the students. Results: The results suggested that the comprehension level of the 30 medical students of the anatomy of the inner ear organs, especially the positional relationships of the semicircular canals and cochlea improved dramatically after they underwent training using this methodology. The medical students assigned high scores to this relational hand modulation method. Conclusion: This “Bang Bang, Hu, Kacha” method seemed to be a very useful for medical education, and allowed easy comprehension and memorization of the inner ear and vestibular anatomical structures.

症例は70歳代男性.数ヵ月前から39℃を超える発熱,咽頭痛,皮疹の出現を繰り返していた.初診時,口腔内および咽頭喉頭にアフタ性潰瘍が多発していたため,急性咽喉頭炎による重症感染症を疑い抗菌薬治療を行った.咽頭喉頭所見は加療により概ね改善し,皮疹も消退傾向であったが,軽微な炎症反応,弛張熱,大球性貧血は遷延していた.貧血の精査目的に骨髄生検を施行.精査中に新たな皮疹も出現したため,皮膚生検を施行した.生検の結果,骨髄異形成症候群を合併したSweet病の診断に至った. 急性咽喉頭炎に皮疹を合併した症例で,抗菌薬治療を行っても症状が遷延する場合には,背景にSweet病や自己免疫疾患などが存在する可能性がある.

Brainstem disorders are often characterized by abnormal eye movements, however, the type of abnormal movements vary depending on the localization and severity of the damage. Here, we report a case of pontine hemorrhage who exhibited horizontal conjugate gaze palsy and disorder of speech discrimination. The 34-year-old man presented with eye pain and dull feeling malaise?, disorder of speech articulation and torpor paralysis ?? of the left side of the body of sudden onset, that developed while he was driving a car. Clinical examination revealed horizontal conjugate gaze palsy, both rightward and leftward, while vertical gaze and convergence were normal. Although the pure-tone audiogram and DPOAE were within normal range, ABR showed prolongation of latency, and reduction of speech discrimination was recognized. MRI revealed evidence of hematoma and edema extending from the mid-dorsal aspect to the right side of the pons. Based on the findings, the patient was diagnosed to have pontine hemorrhage due to hypertension affecting the right facial nerve nucleus, right pyramidal tract, bilateral abducens nuclei, MLF, PPRF and the auditory neural pathway. Although the symptoms of pyramidal tract and auditory disorder resolved by day 19 when he was?? moved to another hospital, the other neurological symptoms were persistent.

The etiology of sudden sensorineural hearing loss is unknown, but viral infection is suspected as one possible cause. We retrospectively studied 102 sudden sensorineural hearing loss patients to evaluate the efficacy of acyclovir therapy. Acyclovir had been administered to 25 patients as single therapy or in combination with corticosteroid or batroxobin. They were given 750mg of acyclovir per day intravenously. These patients were compared with the other 77 patients treated without acyclovir. Hearing recovery was assessed by the criteria of the Sudden Deafness Research Group of the Japanese Ministry of Health and Welfare. In the patients treated with acyclovir, the rate of complete recovery was 56.0%, the rate of recovery was 80.0%, and the rate of efficiency was 88.0%. We found significantly better recovery in the group therapy by acyclovir than in the group without acyclovir.
