    Abstract

    Benign paroxysmal positional vertigo (BPPV) is associated with menopause and/or osteopenia. Morphological changes in the otoconial layer have been reported after ovariectomy (OVX). Moreover, hormone replacement therapy decreases BPPV risk. However, knowledge concerning the effect of hormonal therapy on the otoconial changes caused by estrogen deficiency is limited. We aimed to examine the effect of hormonal therapy on otoconial changes caused by estrogen deficiency. We hypothesized that hormonal therapy could reduce otoconial changes caused by OVX. Eight-week-old C57BL/6 mice were divided into four groups: sham operation with implantation of vehicle (sham + v), OVX with implantation of vehicle (OVX + v), OVX with implantation of estradiol (E2) (OVX + E2), and OVX with implantation of raloxifene (RAL) (OVX + RAL) groups. Otoconial layer volume was measured by micro-CT at 4 weeks after OVX or the sham operation. The otic bullae were removed; immunohistochemistry was performed for estrogen receptor alpha and 4-hydroxynonenal. Otoconial layer volume was significantly higher in the OVX + v than in the sham + v group. E2 and RAL significantly reduced these changes in the endometrial layer. The staining of estrogen receptor alpha and 4-hydroxynonenal were stronger in the OVX + v than in the sham + v group but equal in the sham + v, OVX + E2, and OVX + RAL groups. These results indicate that E2 and RAL are effective against morphological changes of the otoconial layer caused by estrogen deficiency via oxidative stress reduction.

    OBJECTIVE: The aim of this study was to investigate the association of the prognosis and severity of idiopathic sudden sensorineural hearing loss (ISSNHL) with cervical ultrasonographic findings suggestive of cardiovascular risk. METHODS: Seventy-four inpatients with ISSNHL were included in our study. Cervical ultrasonography was performed to evaluate the common carotid artery (CCA), internal carotid artery (ICA), and vertebral artery (VA). The peak systolic velocity, end diastolic velocity, intima-media thickness, pulsatility index (PI), and resistance index (RI) were evaluated. We investigated the relationship of these variables with the severity and prognosis of ISSNHL. RESULTS: ICA-PI, ICA-RI, and CCA-RI were significantly higher in patients with poor hearing prognosis than in those with good prognosis. The variables of VA were not related to the prognosis of ISSNHL. There were no statistically significant differences between ISSNHL severity and cervical ultrasonographic findings. CONCLUSIONS: We found that PI and RI might be prognostic factors for ISSNHL.

    We report the case of a patient with traumatic pseudoaneurysm, who developed massive bleeding during endoscopic sinsu surgery. A 23-year-old drunk man sustained severe injuries when he fell from the second floor of his home and was transported to the hospital emergency department. He was diagnosed as having traumatic subarachnoid hemorrhage, brain contusion, skull base fracture, pneumoencephalopathy, maxillary fracture, right distal radius fracture, and admitted to the hospital. He was transferred to our oral surgery department for maxillary fixation to treat the maxillary fractures. Cerebrospinal fluid rhinorrhea was suspected due to a skull base fracture, and the patient was referred to the otorhinolaryngology department. Since there was no obvious cerebrospinal fluid leakage, the patient was followed up. However, as the rhinorrhea persisted, endoscopic sinus surgery was performed under general anesthesia to confirm and treat cerebrospinal fluid leakage. The sphenoid sinuses of both sides were filled with clot-like masses with strong pulsations. Hematomas were suspected, but when a piece of tissue was removed from the left sphenoid sinus mass, arterial bleeding occurred. Hemostasis was accomplished by immediate compression with gauze. Emergency cerebral angiography revealed a pseudoaneurysm in the right internal carotid artery, and pseudoaneurysm trapping (internal carotid artery blockage) with STA-MCA bypass and high flow bypass (ECA-RAG-MCA) was performed. After the operation, there was no apparent paralysis, and MRI revealed no apparent infarct. Four years after the operation, there is no evidence of aneurysm recurrence. This case suggests that in cases that develop refractory epistaxis after head injury, traumatic internal carotid artery pseudoaneurysm must be considered in the differential diagnosis, and cerebral angiography must be performed immediately.

    症例は10歳女児で、動悸と焦燥感、前頸部腫脹を主訴に受診した。採血でfree T3およびT4の上昇を認め、TSHは測定感度以下であったためバセドウ病と診断した。また、血小板が10.1万/μLと低値であった。チアマゾール(MMI)で順調にホルモン値は改善したが、血小板が治療開始3ヵ月で3.4万/μLまで低下した。骨髄検査で異形成などはなく、薬剤性および先天性血小板減少と診断した。MMIからプロピルチオウラシル(PTU)へ変更した。血小板は5.4万/μLまで改善したが、甲状腺腫大は残存した。頸部CTでは、甲状腺のび漫性腫大を認めた。内服によるコントロールが困難なことから手術適応ありと判断した。手術日直前の採血で血小板が6.6万/μLと再度低下したため、PTUによる薬剤性血小板減少を疑い、手術延期となった。手術日1週間前より入院のうえガンマグロブリンを投与した。十分な量の血小板数の改善を認め、甲状腺機能もほぼ正常範囲となったため、全身麻酔下の甲状腺全摘出を施行した。術後7日目より甲状腺ホルモン補充を開始し、8日目に退院した。術後は、現在に至るまで経過良好である。

    軟口蓋穿孔の原因は多岐に渡り、診断に苦慮することがある。今回われわれは副腎皮質ステロイドの投与で診断に苦慮した軟口蓋穿孔の1例を経験したので文献的考察を加え報告する。症例は35歳女性。左耳痛と難聴を主訴に近医を受診、急性中耳炎として加療を受けるも改善しなかった。軟口蓋穿孔も出現したため副腎皮質ステロイドの漸減投与が行われ精査加療目的に当科紹介受診となった。当科にて細菌検査や病理組織検査を繰り返すも確定診断には至らず、軟口蓋穿孔の改善も認めた。しかし当科受診3ヵ月後に行った気管支鏡検査にて肺結核、上咽頭結核、結核性中耳炎と診断された。抗結核薬を投与され症状は軽快し、1年半経過した現在、症状の再燃を認めていない。(著者抄録)

    小児癌はかつて『不治の病』とされていた時代もあったが、今日では治療の進歩により5年生存率は70%を超え治癒が見込める疾患へと変貌している。その一方で治療による晩期障害として二次発癌が問題となってきている。症例は8歳、女児。2歳時に神経芽腫(Stage IV)を発症し、化学療法、末梢血幹細胞移植、手術、放射線照射を施行し寛解状態を得られた。それから約6年後に右耳下腺腫瘍が出現した。右耳下腺腫瘍摘出術を施行し、術中迅速病理で炎症性変化であったが、永久病理で低悪性度粘表皮癌と診断されたため追加手術を施行した。本腫瘍は小児癌治療による晩期障害の二次発癌と考えられた。術後1年半経過したが再発を認めていない。(著者抄録)

    高度麻痺に対する顔面神経減荷手術は神経変性の進行を抑えることが目的であり、麻痺発症後2週間以内の手術が望ましいとされる。しかし実臨床では2週間以内に手術ができる症例は少なく、また2週間以上経過した症例に対する手術成績は満足いくものではない。そこで我々は再生治療を導入した顔面神経減荷手術を開発するために様々な検討を行ってきた。基礎実験としてモルモットの顔面神経麻痺モデルを用い、塩基性神経芽細胞成長因子(bFGF)が顔面神経の再生に有効であることを見出した。臨床試験としては発症後2週間以上が経過した顔面神経麻痺症例に対してbFGFを徐放化し神経に投与する新たな顔面神経減荷手術を行ってきた。従来の顔面神経減荷手術に比べて手技も容易であり、これまでの結果では発症後時間が経過した高度麻痺症例においても、従来法に比べて予後が良好であることが示されている。この新たな顔面神経減荷手術を紹介する。(著者抄録)

    The prognosis for childhood cancer has improved drastically recently due to advances in anti-tumor therapy. The current 5-year survival rate is over 70%
    hence, childhood cancer is curable. However, secondary malignant neoplasms are a late effect of primary cancer therapy. The patient was an 8-year-old girl. When she was 2 years old, she suffered from neuroblastoma (stage IV). Chemotherapy, hematopoietic stem cell transplantation, surgery, and radiotherapy brought about complete remission. However, 6 years later a right parotid gland tumor appeared. A tumorectomy was then conducted, and intraoperative consultation revealed inflammation of the parotid gland. The final pathological diagnosis was low-grade mucoepidermoid carcinoma of the parotid gland, so we performed an additional operation. This cancer seemed to be secondary malignant neoplasm induced later following childhood cancer therapy. Eighteen months have passed since her final operation, and there is no recurrence of cancer.
