Myeloproliferative neoplasm (MPN) including essential thrombocythemia (ET) is a reported risk factor for EHPVO due to underlying persistent thrombophilia. A Japanese woman in her 40s was referred to our hospital with a 1-month history of gastric variceal bleeding due to EHPVO. Laboratory investigation showed thrombocytosis despite portal hypertension. She had a mutation in clonal marker JAK2V617F with EHPVO, which prompted us to consult a hematologist. A bone marrow biopsy revealed megakaryocyte lineage proliferation, which confirmed a diagnosis of ET. Esophagogastroduodenoscopy revealed esophagogastric varices (LsF2CbRC2, Lg-cF1RC1), and abdominal computed tomography and angiography revealed splenomegaly and portal vein thrombosis with cavernous transformation, which suggested EHPVO. The patient had a history of ruptured esophagogastric varices and required prophylaxis against further variceal bleeding before antithrombotic therapy for EHPVO with ET. We performed laparoscopic Hassab's operation followed by endoscopic variceal ligation (EVL) and hematological cytoreduction therapy. Laparoscopic Hassab's operation and three bi-monthly EVL procedures improved the esophagogastric varix (LmF0RC0, Lg-f F0RC0) at 6 months after surgery. Cytoreduction therapy reduced platelet count to 60.1 × 104/uL, and the patient was very healthy at 7 months after surgery. Patients with EHPVO are traditionally referred to a gastroenterologist for abdominal pain, intestinal bleeding, or refractory ascites; however, hypercoagulative disease may be occult in such patients and require the attention of a hematologist. When treating patients with EHPVO, gastroenterologists should screen for hematological disease, including MPN.","PeriodicalId":56076,"journal":{"name":"Journal of Nippon Medical School","volume":" ","pages":"541-547"},"PeriodicalIF":1.2,"publicationDate":"2024-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9967160","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}

The masses were localized only in the left kidney without suspected metastatic lesions at other sites. The patient was referred to our department for further evaluation and treatment under a diagnosis of suspected metastatic lung carcinosarcoma of the left kidney. On enhanced CT, the left renal masses, the largest of which had a diameter of 40×36 mm had thick irregular walls gradually enhanced by the contrast media and an internal low-attenuation area. The masses showed heterogeneous signal intensity with a pseudocapsule on T2-weighted magnetic resonance imaging. Clinical symptoms such as fever or costovertebral angle tenderness were absent, and blood and urine tests were not sufficiently inflammatory to suggest a renal abscess. Histopathological findings on CT-guided renal biopsy revealed only inflammatory tissue and no tumor cells. However, because lung carcinosarcoma metastatic nodules could not be ruled out, laparoscopic left nephrectomy was performed for a definitive diagnosis and curative intent. The pathological diagnosis was renal abscess without malignant lesions. Here, we present a case of renal abscess mimicking metastatic lesions in a patient with lung carcinosarcoma. Accurately differentiating renal abscesses from metastatic renal tumors before treatment is often difficult.

Guidelines for preventing mother-to-child transmission have been introduced to reduce the incidence of early-onset infection, but guidelines for controlling the late-onset form are lacking. Recently, the trans-breastfeeding route of transmission has been highlighted as an example of late-onset infection, but no consensus on how to manage such infections has been reached. In this report, we describe a case of late-onset bacteremia/meningitis in a neonate suspected to have been infected with GBS via breastfeeding. A vaginal culture test of the mother at 35 weeks' gestation was negative for GBS. Since she had symptoms of mastitis, breast milk and nipple cultures were also tested and found to be positive for the strain of GBS identified in the neonate on genetic analysis. Diagnosis of trans-mammary GBS infection is challenging because breastfeeding-related events are difficult to identify. In our case, the diagnosis was based on the mother's history of mastitis, and the patient was treated without escalation to sequelae. When a neonate develops a fever, physicians should consider GBS infection and examine the mother's medical history to facilitate accurate diagnosis, especially if the history includes mastitis. A breast milk culture should be performed if the mother has mastitis, especially in cases of infection in preterm infants and in recurrent cases.","PeriodicalId":56076,"journal":{"name":"Journal of Nippon Medical School","volume":" ","pages":"495-498"},"PeriodicalIF":1.2,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9572315","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}

An 82-year-old woman visited our hospital for chronic heart and renal failure. She had a history of breast cancer, myocardial infarction, and hemorrhoidal fistula and was initially hospitalized for ischemic colitis. Subsequent lower gastrointestinal endoscopy revealed extensive ulcerative lesions in the ascending, transverse, and descending colon. Histopathologically, small vessels exhibited multiple fibrin thrombus formations. Based on histopathological and endoscopic results, the presence of an underlying disease was suspected. Flow cytometric analysis showed that erythrocytes and granulocytes had 5.5 and 86.4% CD55- and CD59-negative cells, respectively. The patient was ultimately diagnosed with PNH and considered severely ill, given the ischemic colitis-induced abdominal pain and the need for red blood cell transfusions (4-6 units per month). Accordingly, the patient was administered ravulizumab. Ischemic enteritis did not relapse following ravulizumab administration, and transfusion dependence improved. If a patient with ischemic colitis presents atypical lower gastrointestinal endoscopic findings, it is important to explore the presence of an underlying disease.","PeriodicalId":56076,"journal":{"name":"Journal of Nippon Medical School","volume":" ","pages":"512-517"},"PeriodicalIF":1.2,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9967157","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}

In infants, bacterial infections, especially invasive bacterial infections, can result in poor outcomes and require careful evaluation and treatment. Furthermore, the possibility of AFBN should not be overlooked, because bacteriuria or leukocyturia may be absent and can flare up if antimicrobials are not administered for an adequate duration.

A 79-year-old man was referred to our department for evaluation of persistent pharyngeal pain and dysphagia after thoracic aortic aneurysm surgery. He had restricted bilateral vocal fold abduction, and the NGT had been placed for nearly 120 days. After induction of general anesthesia, the patient underwent laryngeal examination using a rigid curved laryngoscope, which revealed ossified cricoid cartilage in the postcricoid area, leading to confirmation of NGTS. The NGT was removed, and the protruding bony lesion was debrided. Subsequently, the patient underwent gastrostomy to improve his nutritional status. One month later, the postcricoid lesion improved, and the patient was able to tolerate an oral diet. The pathophysiology of NGTS is thought to involve ulceration of the postcricoid mucosa and injury of the posterior cricoarytenoid muscle by contact with the NGT. Although the treatment has not been established, early removal of the NGT is important. In the present case, the rigid curved laryngoscope was useful for resection of the bony lesion, which contributed to early epithelialization and symptom improvement.","PeriodicalId":56076,"journal":{"name":"Journal of Nippon Medical School","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2024-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142019704","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}

Most cases involve gastric anisakiasis, whereas intestinal anisakiasis is rare. This report describes the case of a 63-year-old Japanese woman with a history of raw fish consumption who presented with acute-onset abdominal pain and vomiting. Abdominal computed tomography (CT) demonstrated thickened small bowel loops and ascites on the liver surface. The patient was admitted for supportive care. On the second day of hospitalization, contrast-enhanced abdominal CT revealed that the ascites had moved from the liver surface to the pouch of Douglas. On the fifth day of hospitalization, the patient was discharged with a substantial improvement in abdominal pain. Five days after the discharge, her eosinophil count was elevated, and parasitic disease was therefore suspected. Anti-Anisakis IgG/A and IgE (RAST) antibody levels were elevated, confirming the diagnosis of intestinal anisakiasis. A review of 51 reported cases of intestinal anisakiasis suggests that the presence of ascites and measurement of anti-Anisakis antibody titers are helpful for diagnosis in cases presenting with nonspecific abdominal symptoms after consumption of raw or undercooked fish.","PeriodicalId":56076,"journal":{"name":"Journal of Nippon Medical School","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141428331","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}
