Mesenteric hematoma is an uncommon condition caused by focal bleeding in the mesenteric vessels. Hematomas are related to trauma, pancreatitis, arteriopathy, and the use of antithrombotic agents. Although hematomas cause intestinal stenosis by compressing the adjacent small bowel, duodenal stenosis due to hematoma is rare. Therefore, the treatment indications for cases of hematoma with stenosis have not been established. We herein report a case with a large mesenteric hematoma that caused duodenal stenosis by compressing the third portion of the duodenum. Stenosis was successfully ameliorated after long-term use of a double elementary diet tube.

An 89-year-old woman underwent examinations for leg edema. Blood tests indicated low nutrition and low pancreatic enzymes, and a stool examination indicated fatty stool. Computed tomography showed pleural effusion, ascites, and cystic lesions in the pancreatic head and mural nodules within the cysts. Pancreatic juice cytology revealed adenocarcinoma. The diagnosis was pancreatic exocrine insufficiency caused by intraductal papillary mucinous carcinoma. The patient did not wish to undergo surgery. Therefore, diuretics, component nutrients, and pancreatic exocrine replacement therapy using pancrelipase were initiated. After starting treatment, her leg edema, pleural effusion, and ascites disappeared, and her activities of daily living improved markedly.

Pulmonary tumor thrombotic microangiopathy (PTTM) is a rare cancer-related complication that induces pulmonary hypertension (PH). PTTM can be caused by recurrent cancer, with 12 years being the longest reported interval from primary cancer to the development of PTTM. We herein report a 74-year-old woman who presented with dyspnea due to PH. The postmortem diagnosis was PTTM caused by recurrent gastric cancer 26 years after total gastrectomy. An autopsy revealed PTTM-specific histological characteristics. Our findings indicate that PTTM should be considered as a diagnosis for patients with a history of cancer who develop PH, even several decades after treatment.

A 54-year-old man with early repolarization syndrome (ERS) implanted with an implantable cardioverter-defibrillator (ICD) developed persistent atrial fibrillation (AF) three years after the implantation. Similarly, the remote monitoring system begun frequently detecting ventricular fibrillation (VF) and polymorphic ventricular tachycardia (PVT). Longer RR intervals were repeatedly observed just before the initiation of PVT/VF. Catheter ablation for AF successfully diminished both the PVT and VF events.

A 72-year-old Japanese woman with systemic sclerosis was admitted to our hospital because of symptoms of heart failure. Cardiovascular magnetic resonance (CMR) imaging had shown that extensive myocardial fibrosis secondary to systemic sclerosis was the main cause of heart failure. One month after CMR, she had complete atrioventricular (AV) block. It was suggested that the progression of fibrosis to the AV node caused complete AV block. This case report has clinical implications in highlighting the fact that CMR is useful for not only evaluating the present pathophysiology but also predicting future adverse events in patients with systemic sclerosis.

A 54-year-old Japanese woman was admitted to our ward because of recurrent chest pain at rest for 2 months. She had been treated with nivolumab, an immune checkpoint inhibitor for inoperable advanced hypopharyngeal cancer for 21 months. She had no chest pain after cessation of nivolumab treatment. Cardiac catheterization confirmed the presence of vasospastic angina. Benidipine 8 mg was started, and she had no chest pain even after resuming therapy with nivolumab. Vasospastic angina is an adverse effect of nivolumab.

Phospholamban p.Arg14del is reported to cause hereditary cardiomyopathy with malignant ventricular tachycardia (VT) and advanced heart failure. However, the clinical courses of Japanese cardiomyopathy patients with phospholamban p.Arg14del remain uncharacterized. We identified five patients with this variant. All patients were diagnosed with dilated cardiomyopathy (DCM), developed end-stage heart failure and experienced VT requiring implantable cardioverter defibrillator discharge. Four patients survived after implantation of a left ventricular assist device (LVAD), while one patient who refused LVAD implantation died of heart failure. Based on the severe course of the disease, we propose genetic screening for phospholamban p.Arg14del in DCM patients.

Chylous ascites (CA) is the accumulation of fluid with a high triglyceride content in the peritoneal cavity. Only two cases in the literature have reported CA with hyperthyroidism. A 28-year-old previously healthy woman presented with gradual-onset abdominal swelling, exertional dyspnea, and diarrhea. Hyperthyroidism and heart failure were diagnosed using laboratory investigation and echocardiography. Ultrasonography revealed a large amount of ascites. The ascitic fluid was milky with elevated triglyceride levels. Treatment with anti-thyroid therapy and diuretics improved all symptoms, and the free triiodothyronine (T3) level normalized after five days. Hyperthyroidism and heart failure should be considered as reversible causes of CA.

A man in his 30s injected insulin several times into his abdomen and was found dead several hours later. Micropathological findings showed alveolar injury with hemorrhaging and cerebral parietal lobe nerve cell edema. Biochemical examinations showed that the blood insulin level was high, significantly so at the insulin injection sites. The blood glucose and C-peptide levels were low. The insulin level in the kidneys was low. In forensic medicine, a postmortem diagnosis of insulin subcutaneous injection is often difficult. When insulin injection is suspected, particularly high insulin levels can be expected at the insulin injection site, rather than in the blood.

A 50-year-old Japanese woman with anti-melanoma differentiation-associated gene 5 antibody (anti-MDA5 antibody)-positive dermatomyositis presenting with rapidly progressive interstitial pneumonia was treated with corticosteroids and cyclosporine. She developed nephrotic syndrome during the treatment regimen with corticosteroids and cyclosporine. A kidney biopsy revealed a thrombotic microangiopathy (TMA) glomerular lesion.
Anti-MDA5 antibody-positive dermatomyositis is prone to severe interstitial lung disease (ILD) and is often exacerbated and refractory to treatment. Renal symptoms might be due to TMA of the kidney, and this may be a sign that more intensive treatment is needed. Patients sometimes develop acute kidney injury, which may be due to the TMA.

A 70-year-old man received pembrolizumab as a second-line treatment for squamous cell lung cancer of the lower right lobe. After three courses, proteinuria and hematuria were observed, which worsened after seven courses. He was diagnosed with a combination of IgA nephropathy and active interstitial nephritis. Steroid pulse therapy was started, and the dose of prednisolone was gradually reduced from 60 mg/day. Renal dysfunction as an immune-related adverse event of pembrolizumab monotherapy for non-small cell lung cancer has been reported previously. Therefore, establishing a system for the early detection and treatment that distinguishes immune-related glomerular diseases is essential.

A 63-year-old man with an 8-year history of proteinuria was diagnosed with nephrotic syndrome, and a renal biopsy was performed. Light and electron microscopic analyses showed classic features of idiopathic membranous nephropathy (IMN). However, immunofluorescence tests revealed solitary polyclonal granular IgA deposition along the glomerular capillary walls, rather than IgG, which is often dominant in IMN. The combined use of corticosteroids and calcineurin inhibitor was noticeably effective in reducing proteinuria and improving edema in the current case. Two additional rare cases of IMN with solitary IgA deposition were reviewed, and long-term surveillance is still warranted to characterize its clinicopathological features and outcome.

A 46-year-old woman developed takotsubo cardiomyopathy and nephrotic syndrome. The first kidney biopsy suggested non-immune-complex-mediated membranoproliferative glomerulonephritis (MPGN), and she was diagnosed with glomerular endothelial injury associated with takotsubo cardiomyopathy. A second biopsy was performed two years later because of persistent proteinuria despite renin-angiotensin system inhibition. This biopsy indicated non-immune-complex-mediated MPGN, but a mesangial and subendothelial substance of a higher electron density than that in the first biopsy was detected, suggesting the possibility of glomerular disease with non-immune deposits rather than endothelial injury. Finally, she was diagnosed with fibronectin nephropathy. Although rare, fibronectin glomerulopathy should be considered in non-immune-complex-mediated MPGN.

Branchio-oto-renal syndrome is an autosomal dominant disorder characterized by branchial anomalies, hearing loss, and renal urinary tract malformations. We herein report a 32-year-old Japanese man with a right preauricular pit, bilateral mixed hearing loss, and malposition of the right kidney who presented with proteinuria. The findings of a left kidney biopsy were compatible with a perihilar variant of secondary focal segmental glomerular sclerosis. A trio exome analysis conducted among the patient and his parents failed to identify the causal gene variant, despite a sporadic pattern. His kidney function remained stable for 11 years with an angiotensin II receptor blocker.

A 58-year-old man was diagnosed with stage IVB lung adenocarcinoma in the right upper lobe and underwent systemic chemotherapy. Seven months after the diagnosis, large left pleural and pericardial effusion was detected. The patient developed both chylothorax and chylopericardium following superior vena cava (SVC) obstruction with mediastinal lymphadenopathy caused by lung carcinoma. Since conservative treatment of the chyle leakage was ineffective, we administered radiotherapy to treat the SVC obstruction and mediastinal lymphadenopathy. After radiotherapy, the chylothorax and chylopericardium gradually resolved, and no further chyle leaks were identified on follow-up computed tomography. This case indicates that radiotherapy can be used to ameliorate lung cancer-related chylothorax and chylopericardium.

Diffuse alveolar hemorrhaging (DAH) due to oral anticoagulation (OAC) is a life-threatening condition that leads to severe respiratory failure. There is a clinical dilemma in that OAC-induced DAH often forces the discontinuation of OAC therapy and the administration of high-dose corticosteroids, which increases the risk of stroke and cardiovascular events. We herein report the first case of OAC-induced DAH and atrial fibrillation (AF) in a patient who completely discontinued OAC therapy and high-dose corticosteroids after experiencing percutaneous left atrial appendage (LAA) occlusion. This case suggests that percutaneous LAA closure may aid in the management of OAC-induced DAH and AF.

Protein-losing enteropathy (PLE) is a rare syndrome characterized by hypoproteinemia due to gastrointestinal (GI) protein loss. Primary intestinal follicular lymphoma (PIFL), a specific variant of follicular lymphoma with essential only GI involvement, has not been reported as an etiology of PLE. We herein report a case of PLE complicated with PIFL that was successfully treated with rituximab, resulting in rapid improvement of PLE and a complete response of PIFL. Macroscopic findings of ulcerative lesions with diffuse involvement, which were precisely described by capsule and double-balloon enteroscopy at the diagnosis, also improved following the treatment. This case provides a clue suggesting factors that promote PLE in PIFL.

Peritoneal lymphomatosis (PL) is a rare presentation of malignant lymphoma cases, many of which are diagnosed as diffuse large B-cell lymphoma (DLBCL) and characterized by aggressive clinical courses. We herein report a 63-year-old woman presenting with the rapid development of abdominal distention due to bulky peritoneal tumors. The pathological evaluation of a needle biopsy sample, combined with flow cytometry, yielded the diagnosis of DLBCL. Prompt chemotherapeutic intervention resulted in favorable disease control and sustained complete remission. It is necessary to diagnose cases of DLBCL presenting as PL early to ensure prompt treatment and prevent mortality.

A 59-year-old man with advanced Parkinson's disease treated using levodopa-carbidopa intestinal gel (LCIG) presented with leg edema, hypoalbuminemia, and proteinuria at 1 year after the treatment. He subsequently developed a generalized tonic-clonic seizure, and brain magnetic resonance imaging indicated vasogenic edema in the white matter of the left frontal subcortex. He was diagnosed with nephrotic syndrome (NS) and atypical posterior reversible encephalopathy syndrome (PRES). LCIG cessation and corticosteroid treatment improved the NS. To our knowledge, this is the first case report of NS and atypical PRES in patients with Parkinson's disease. Patients being treated with LCIG should be closely monitored for NS.

We herein report a patient with giant cell arteritis (GCA) who developed pneumatosis intestinalis (PI) while she was in a clinically sustained remission phase. A 79-year-old woman with GCA involving the thoracic aorta and its first branches to the posterior tibial arteries had been treated with high-dose prednisolone. Nine weeks after initiating treatment and while in clinically sustained remission with a normal CRP level, PI and pneumoperitoneum were incidentally found during scheduled positron emission tomography-computed tomography, which also revealed slight residual inflammation of GCA. This is a very rare case of PI complicated by GCA, and we discuss the possible relationships.

We herein report a 60-year-old woman who experienced severe flare of rheumatoid arthritis (RA) and Epstein-Barr virus (EBV) positivity following administration of the messenger ribonucleic acid (mRNA)-type severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine. Since 40 years old, she had been in long-term remission of anti-citrullinated protein antibody-positive RA. Ten days after SARS-CoV-2 vaccination, she presented with a high fever and polyarthritis, active synovitis on joint ultrasound, a clinical disease activity index of 35, and positivity for anti-early antigen, diffuse type and restricted type (EA DR) IgG and EBV deoxyribonucleic acid (EBV-DNA). Tocilizumab was introduced to treat RA. The RA disease activity disappeared, and anti-EA DR IgG and EBV-DNA became negative.
