During a 6-month period, a 3-year-old girl experienced monthly fever (39°C) episodes persisting 5 to 12 days and two episodes of ankle arthralgia and skin rash during fever. No abdominal or chest pain was noted. Blood tests performed at the time of fever revealed elevated CRP levels and blood sedimentation rates. Urinalysis and bone marrow examination results were unremarkable. Genetic testing for hereditary autoinflammatory disease syndromes showed E84K MEFV gene mutations. After diagnosing atypical familial Mediterranean fever, oral colchicine alleviated the febrile attacks and improved family quality of life. Fever, arthralgia, and skin rash disappeared after oral colchicine, which is effective for atypical familial Mediterranean fever. During the 6 months before the diagnosis, periodic fever disrupted the daily lives of the entire family. The patient was absent from nursery school during fever. The patient's illness affected her mother's health. The mother was concerned about her child's unknown fever, which resulted in depression and the need for psychiatric medication. Colchicine resolved the febrile episodes, and resolution of the patient's symptoms alleviated her mother's depression. This case shows that genetic testing for periodic fever syndrome can improve family quality of life.","PeriodicalId":56076,"journal":{"name":"Journal of Nippon Medical School","volume":" ","pages":"480-485"},"PeriodicalIF":1.4,"publicationDate":"2026-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144509602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Case 1 was a 70-year-old man treated with an Impella 2.5, followed by urgent ISCAB on the day of hospitalization, for a left main trunk lesion. Use of an apical suction device to position the heart to expose an obtuse marginal branch caused Impella obstruction by applying suction to the left ventricular wall, interrupting revascularization; however, one revascularization was achieved. Case 2 was a 79-year-old man treated with an Impella CP for a three-vessel lesion until ISCAB 4 days later. The Impella was stabilized with appropriate positioning by adjusting the bed angle, minimal heart compression with a deep pericardial stitch without pulling on the cardiac apex, and sufficient preload, even during posterolateral branch anastomosis. Four revascularizations were eventually achieved. Multiple innovations to prevent Impella contact with the left ventricle as described herein improve ISCAB safety, particularly during peripheral circumflex branch anastomosis.","PeriodicalId":56076,"journal":{"name":"Journal of Nippon Medical School","volume":" ","pages":"474-479"},"PeriodicalIF":1.4,"publicationDate":"2026-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144509603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is often associated with atresia, stenosis, or obstruction of the external auditory canal. In cases of microtia, the incidence of a normal external auditory canal, congenital external auditory canal stenosis, and congenital complete closure of the external auditory canal (aural atresia) is reported to be 8%, 8%, and 84%, respectively. Congenital stenosis of the external auditory canal can sometimes be accompanied by intractable otorrhea and otalgia, raising the possibility of complications of external auditory canal cholesteatoma. Here, we report a case of an adult with microtia and external auditory canal stenosis who presented to our clinic with complaints of otalgia. A large external auditory canal cholesteatoma was found in the patient's left ear. Although cholesteatoma is common in cases of canal stenosis, its extensive spread within the temporal bone is quite rare. A temporal bone-targeted computed tomography scan revealed a soft tissue shadow in the left external auditory canal with distensible expansion and bony destruction in the upper, anterior, and posterior walls of the external auditory canal. In patients with microtia who experience severe aural pain, the possibility of latent extended cholesteatoma should be considered.","PeriodicalId":56076,"journal":{"name":"Journal of Nippon Medical School","volume":" ","pages":"468-473"},"PeriodicalIF":1.4,"publicationDate":"2026-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143702255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents a rare case of asystole during suspension laryngoscopy. A 58-year-old woman with an unremarkable medical history underwent suspension laryngoscopy for a left polypoid vocal cord under general anesthesia. Anesthesia induction and tracheal intubation were performed without complications. However, upon inserting a direct laryngoscope and exposing the larynx, her heart rate gradually decreased and asystole occurred. The direct laryngoscope was immediately removed, and atropine sulfate was injected. Spontaneous circulation was restored after 20 s of asystole. The direct laryngoscope was then re-inserted, and the operation was successfully completed without complications. Asystole was attributed to stimulation of the pharyngolaryngeal mucosa through direct laryngoscope-induced vagal reflex. This case highlights the need for surgeons and anesthesiologists to be aware of this rare but potentially life-threatening complication and emphasizes the importance of vigilant electrocardiography monitoring during direct laryngoscope adjustment.","PeriodicalId":56076,"journal":{"name":"Journal of Nippon Medical School","volume":" ","pages":"446-449"},"PeriodicalIF":1.4,"publicationDate":"2026-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143702277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is believed to be caused by obstruction of the salivary duct by mucofibrinous plugs and is often misdiagnosed as other types of sialadenitis, such as Sjögren's syndrome, or sialadenitis caused by bacterial or viral infection. Although specific diagnostic criteria have not been defined, the typical pathological finding of sialodochitis fibrinosa is infiltration of lymphocytes and eosinophils into the interstitium around the salivary ducts. Sialendoscopy, a minimally invasive endoscopic technique, has recently been used to diagnose and treat diseases of the salivary glands. This new technique can be used to irrigate and dilate the salivary gland ducts under direct vision. We successfully used sialendoscopy to diagnose and treat sialodochitis fibrinosa, making this the first reported use of this technique for salivary gland biopsies. Sialendoscopy is a modern approach to salivary gland disorders that was helpful for understanding, diagnosing, and managing sialodochitis fibrinosa.","PeriodicalId":56076,"journal":{"name":"Journal of Nippon Medical School","volume":" ","pages":"440-445"},"PeriodicalIF":1.4,"publicationDate":"2026-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143702257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although CP is usually treated surgically or with hormonal therapy, there is no standard treatment and recurrence is common. We performed video-assisted thoracoscopic surgery (VATS) for five patients with CP from 2014 to 2023.Methods: Our surgical basic procedure (BP) was as follows. VATS was performed by using one port site for the camera and a 5-cm mini-thoracotomy. Perforated holes or blueberry spots were detected on the diaphragm, and lesions were ligated with an endoscopic loop. After reefing by ligation, the diaphragm was covered with a polyglycolic acid sheet. Three methods were used: (A) BP only (one case); (B) BP with tetracycline plus OK432 (two cases); (C) BP with tetracycline (two cases); because the use of OK432 (an anti-cancer agent) was disallowed in 2019 in our Institutional Review Board rules for patients with benign disease.Results: Age ranged from 33 to 45 years (mean, 38.6±5.1 years), and CP occurred on the right side in all cases. Recurrence occurred in only two of the five cases (one case each for procedures B and C).Conclusion: Our procedure (diaphragm reefing by ligation and covering with a polyglycolic acid sheet) was a more convenient and more effective treatment for CP.","PeriodicalId":56076,"journal":{"name":"Journal of Nippon Medical School","volume":" ","pages":"463-467"},"PeriodicalIF":1.4,"publicationDate":"2026-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143702284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
