Objective Glucose-dependent insulinotropic polypeptide (GIP) is speculated to worsen growth hormone (GH) hypersecretion in acromegaly and to be a cause of paradoxical increases in GH (PI-GH) during 75-g oral glucose tolerance testing (75-g OGTT). Dipeptidyl peptidase-4 inhibitors (DPP4is), which increase the circulating concentration of active GIP, are frequently administered to diabetic patients, including those with acromegaly. We aimed to determine whether or not the administration of a DPP4i increases GH concentration, especially in patients demonstrating PI-GH during a DPP4i-OGTT, in which a DPP4i was administered immediately before 75-g OGTT. Methods This prospective cross-sectional study was carried out on acromegalic patients admitted to Hokkaido University hospital between June 2011 and May 2018. The participants underwent both 75-g OGTT and DPP4i-OGTT. For those who underwent surgery, immunohistochemical staining and quantitative polymerase chain reaction (PCR) for the GIP receptor (GIPR) were performed on the resected pituitary adenomas. Results Twenty-five percent of the participants had PI-GH confirmed (3 of 12 cases). Two of the three participants who demonstrated PI-GH exhibited higher circulating GH concentrations during DPP4i-OGTT than during OGTT. The increase in plasma glucose was reduced during DPP4i-OGTT compared to during 75-g OGTT, suggesting that the increase in GH during DPP4i-OGTT was due not to high glucose concentrations but instead increased GIP caused by the administration of DPP4i. The adenoma from one participant with PI-GH displayed positive immunostaining for GIPR and a higher GIPR messenger ribonucleic acid (mRNA) expression than the others. Conclusion DPP4i may enhance the GH secretion response during glucose loading, especially in individuals with PI-GH.

Eradication of H. pylori in patients allergic to penicillin should be performed using regimens without penicillin derivatives. We treated a total of 28 patients allergic to penicillin with a proton pump inhibitor (PPI), metronidazole (250 mg bid) and sitafloxacin (100 mg bid) for one to two weeks. At four to eight weeks after the treatment, the patients underwent the [13C]-urea breath test. The overall eradication rate was 100.0%. Mild adverse events were observed. Triple therapy with a PPI, metronidazole and sitafloxacin is well tolerated and effective for the eradication of H. pylori in patients allergic to penicillin.

Epidermoid cysts presenting within an intrapancreatic accessory spleen are rare non-neoplastic cysts typically occurring in the pancreatic tail. This entity is difficult to diagnose given there are many types of pancreatic neoplastic cysts. We herein describe two cases of an epidermoid cyst within an intrapancreatic accessory spleen for which we performed a resection by laparoscopic distal pancreatectomy. Epidermoid cysts in an intrapancreatic accessory spleen should therefore be considered in the differential diagnosis of pancreatic tail cystic lesions. Laparoscopic distal pancreatectomy can be a useful, minimally invasive surgical approach for treating these cysts as well as for the treatment of benign or low-grade malignant tumors located in the pancreatic body or tail.

A 75-year-old man with paroxysmal atrial fibrillation developed a traumatic intracranial hemorrhage during warfarin treatment. The administration of warfarin was stopped and rivaroxaban therapy, a novel oral anticoagulant (NOAC), was started. Immediately, his platelet count decreased to 3.7×104 /μL. The platelet count recovered rapidly after cessation of rivaroxaban administration. Development of thrombocytopenia and its rapid recovery was observed again after another administration, and subsequent cessation, of the drug. A diagnosis of rivaroxaban-induced thrombocytopenia was made. The incidence of thrombocytopenia due to NOACs is rare. Careful attention to thrombocytopenia, which is associated with a higher risk for life-threatening bleeding, is therefore necessary during treatment with NOACs.

A 79-year-old man was admitted to hospital from his nursing home for treatment of pneumonia, but died 7 days after admission. Legionella pneumonia was diagnosed after isolation of Legionella pneumophila serogroup-5 from sputum culture. The environment of the nursing home was investigated; only water specimens from the 24-hour bath were positive by culture for Legionella pneumophila serogroup-5. Subsequent analysis by pulsed-field gel electrophoresis revealed an identical pattern in isolates from both sputum culture and 24 hour bath water culture. Among 123 inpatients and staff of the nursing home, 17 were found to be seropositive for Legionella pneumophila serogroup-5.

Objective Myocarditis has been described as a complication of influenza. Patients with influenza may have symptoms and abnormal laboratory data (including chest X-ray, electrocardiogram, etc.) suggestive of myocarditis, although few observations have been made regarding the prevalence of asymptomatic myocardial injury. We investigated whether influenza can produce myocardial injury without cardiac symptoms. Methods During the epidemic of influenza A (H3N2) from 1998 to 1999 in Japan, we examined possible cardiac muscle damage associated with influenza in patients without apparent clinical myocardial injury by measuring serum myosin light chain concentrations. Patients Ninety-six influenza-positive patients (46 males and 50 females, average age 43.4 years) without impaired renal function were studied. Results Of these patients, 11 (11.4%) had elevated serum myosin light chain I concentrations. Conclusion Asymptomatic myocardial injury may be present in patients with influenza even when they have no symptoms suggestive of myocardial injury.(Internal Medicine 40: 594-597, 2001)

Achilles tendon xanthoma (ATX) is one of the typical features of familial hypercholesterolemia (FH). The morphological evaluation of ATX by X-ray radiography is widely recognized; however, the utility of other imaging modalities remains unclear. We herein report two cases of FH in which Doppler ultrasound imaging demonstrated a microvascular flow in ATX that only rarely could be observed in normal Achilles tendons. Neoangiogenesis accompanies chronic inflammation and it may play an important role in the deposition of cholesterol crystals leading to ATX. In addition to the morphological evaluation of ATX, the assessment of neoangiogenesis may therefore be essential for the evaluation of ATX.

A 67-year-old man with primary lung adenocarcinoma was hospitalized due to massive bilateral pleural effusion and pericardial effusion after 94 cycles of nivolumab therapy. We were unable to identify the cause of these effusions using blood tests, cytology tests, or bacterial culture of pleural effusion and thoracoscopy. Finally, we administrated corticosteroids, which immediately improved the fluid accumulation. This case may support the introduction of corticosteroids for late-onset pleural and pericardial effusion during immune checkpoint inhibitor (ICI) treatment. However, the safety of rechallenge of ICIs after the improvement of fluid accumulation is controversial.

This report describes a 59-year-old woman who presented with progressive encephalomyelitis with rigidity and myoclonus (PERM)-like symptoms and severe dysautonomia, including orthostatic hypotension, sinus bradycardia, dysuria, and prolonged constipation. Her neurological symptoms improved after immunotherapy, but the dysautonomia persisted. Anti-ganglionic acetylcholine receptor (gAChR) α3 subunit antibodies, which are frequently identified in patients with autoimmune autonomic ganglionopathy, were detected in the pre-treatment serum. The central distribution of the nicotinic acetylcholine receptors, a target of anti-gAChR antibodies, and immunotherapeutic efficacy observed in this case indicate that anti-gAChR α3 subunit antibodies are associated with the PERM-like features accompanied by autonomic manifestations.

Objective The association between frailty and abdominal symptoms has not been evaluated. Methods We conducted a hospital-based, retrospective cross-sectional study of consecutive outpatients ≥65 years old at the Department of Gastroenterology, Juntendo Tokyo Koto Geriatric Medical Center from 2017 to 2019. Patients were included in the study if all of the following information was available from their medical records: patient's profile, the evaluation of osteoporosis, sarcopenia, frailty, nutritional status, findings of upper gastrointestinal endoscopy, and questionnaire results for abdominal symptoms [Frequency Scale for the Symptoms of Gastroesophageal Reflux Disease (FSSG) and Constipation Scoring System (CSS)]. We divided the subjects into frailty and non-frailty groups and investigated the risk factors for frailty. Results Of the 313 eligible study subjects [134 men (42.8%) and 179 women (57.2%); mean age, 75.7±6.0 years; mean body mass index, 22.8±3.6 kg/m2], frailty was noted in 71 cases (22.7%). In a univariate analysis, an older age (p<0.001), female gender (p=0.010), successful eradication of Helicobacter pylori (p=0.049), proton pump inhibitor (PPI) use (p<0.001), laxative/prokinetics use (p=0.008), sarcopenia (p<0.001), osteoporosis (p<0.001), hypozincemia (p=0.002), hypoalbuminemia (p<0.001), low lymphocytes (p=0.004), a high CONUT score (p<0.001), a high FSSG score (p=0.001), and a high CSS score (p<0.001) were significantly associated with frailty. A multivariate logistic regression analysis showed that an older age [odds ratio (OR) 1.16; 95% confidence interval (CI) 1.08-1.24, p<0.001], PPI use (OR 2.42; 95% CI 1.18-4.98, p=0.016), sarcopenia (OR 7.35; 95% CI 3.30-16.40, p<0.001), hypozincemia (OR 0.96; 95% CI 0.92-0.99, p=0.027), a high FSSG score (OR 1.08; 95% CI 1.01-1.16, p=0.021), and a high CSS score (OR 1.13; 95% CI 1.03-1.23, p=0.007) were significantly associated with frailty. Conclusion Advanced age, PPI user, sarcopenia, hypozincemia, a high FSSG score, and high CSS score are associated with frailty.

We report a 65-year-old man with autoimmune glial fibrillary acidic protein astrocytopathy (GFAP-A) who presented with gait disturbance that he had experienced for approximately half a year. On neurological examination, he displayed spastic paraplegia and autonomic dysfunctions including dysuria and constipation. Spinal cord magnetic resonance imaging showed longitudinally extensive spinal cord lesions (LESCLs) extending from the cervical to the thoracic cords. The patient was negative for anti-myelin oligodendrocyte glycoprotein and anti-aquaporin 4 antibodies. Treatment with corticosteroids and intravenous immunoglobulin resulted in a clinical improvement. It is important to distinguish GFAP-A from slowly progressive myelitis with LESCLs.

A 29-year-old man presented with a high-grade fever, headache, and urinary retention, in addition to meningeal irritation and myoclonus in his upper extremities. A cerebrospinal fluid (CSF) examination showed pleocytosis and high adenosine deaminase (ADA) levels with no evidence of bacterial infection, including Mycobacterium tuberculosis. T2-weighted brain magnetic resonance imaging showed transient hyper-intensity lesions at the splenium of the corpus callosum (SCC), bilateral putamen, and pons during the course of the disease. The CSF was positive for anti-glial fibrillary acidic protein (GFAP) antibodies. He was diagnosed with autoimmune GFAP astrocytopathy. The present case shows that the combination of an elevated ADA level in the CSF and reversible T2-weighted hyper-intensity on the SCC supports the diagnosis of autoimmune GFAP encephalopathy.

Objective Parkinson's disease (PD) is a common, progressive, neurodegenerative disorder. With progression of PD, the wearing-off phenomenon occurs more frequently as a motor complication, decreasing the patient's quality of life. The aim of this study was to investigate the risk factors for the wearing-off phenomenon in Japanese PD patients. Methods All of the study participants were clinically diagnosed as having PD. Each patient was assessed for the wearing-off phenomenon based on the findings of clinical assessments and interviews that were conducted during a single visit. The risk factors for wearing-off were analyzed by univariate and multivariate logistic regression analyses. Results Wearing-off was observed in 101 of the 180 (56.1%) patients who were enrolled in this study. The multivariate logistic regression analysis revealed that the onset of PD at ≥69 years of age (odds ratio [OR], 0.22; 95% confidence interval [CI], 0.05-0.88; p=0.032), female sex (OR, 6.49; 95% CI, 2.34-17.99; p<0.001), catechol-O-methyltransferase (COMT) inhibitor treatment (OR, 19.59; 95% CI, 3.55-108.11; p<0.001) and a high daily levodopa dosage (≥600 mg/day) (OR, 7.69; 95% CI, 1.41-41.84; p=0.018) were independent predictive factors for wearing-off in Japanese PD patients. Conclusion Age at the symptomatic disease onset, female sex, COMT inhibitor treatment, and a high daily levodopa dose were associated with the occurrence of wearing-off in Japanese PD patients. Physicians need to consider the risk factors and carefully choose medications for PD patients to postpone the occurrence of this phenomenon for as long as possible.

A 71-year-old man developed postural tremor and was treated as an essential tremor patient. Nine years after the tremor onset, he developed symptoms resembling Fragile-X-associated tremor/ataxia syndrome (FXTAS), including exacerbated (increased coarseness and amplitude) tremor in the right arm, ataxic gait, and brain MRI showed lesions in the bilateral middle cerebellar peduncles (MCP). Evidence of premutation in the form of 83 CGG repeats of the Fragile-X-mental retardation 1 (FMR1) gene confirmed the diagnosis of FXTAS. FXTAS causes various neurological symptoms including in some cases tremor resembling essential tremor in the early stages. FMR1 gene premutation should be checked when the patient develops intention tremor, cerebral dysfunction and/or a brain MRI shows MCP lesions.

We herein report the first case in which an escalated dose of sunitinib was effective, even after dose reduction. A 64-year-old man with gastrointestinal stromal tumor of the small intestine discontinued adjuvant imatinib because of interstitial pneumonia. After two years, peritoneal recurrence was detected. Sunitinib was started at 50 mg/day for 4 weeks every 6 weeks, after which the dosage was reduced to 37.5 mg/day because of grade 1 gastritis, stomatitis, and a fever. Four months later, computed tomography showed progressive disease. As the adverse events were well-controlled by medication, we escalated the dose to 50 mg/day and achieved a partial response.

Polyradiculopathy (PRP) is a rare but serious neurologic complication of cytomegalovirus (CMV) in patients with acquired immunodeficiency syndrome (AIDS). We herein report three cases of CMV PRP in patients with AIDS. Although providing a prompt diagnosis and initiating anti-CMV therapy may achieve clinical improvements, administering single-drug treatment may result in virologic failure. Therefore, introducing antiretroviral therapy is a key step for improving the treatment outcomes of CMV PRP.

A 23-year-old woman was admitted with complaints of swelling and pain in the left breast, fever, polyarthralgia and erythema nodosum. A fine-needle biopsy of the mass in the left breast revealed non-caseous granulomatous lobulitis. A diagnosis of granulomatous mastitis was thus made. The administration of prednisolone 40 mg/day resulted in the resolution of the patient's symptoms, and the breast mass thereafter decreased in size. The mass relapsed during the subsequent prednisolone taper. Additional therapy with methotrexate resulted in complete remission. Granulomatous mastitis should therefore be included in the differential diagnosis of polyarthralgia.
