Duodenal Schwannoma as a Rare Association With Membranous Nephropathy: A Case Report

Publication date: Available online 16 November 2018Source: American Journal of Kidney DiseasesAuthor(s): Zao Zhang, Ting Gong, Helmut G. Rennke, Rick HayashiMembranous nephropathy (MN) associated with malignancies is a well-known entity. However, its association with benign neoplasm is not broadly recognized. A 69-year-old man with recurrent nephrotic syndrome presented with pedal edema and proteinuria of 5 months’ duration. Laboratory results showed hypoalbuminemia and hyperlipidemia. Proteinuria was estimated to be protein excretion of 3.5 g/d. Studies were negative for viral hepatitis, syphilis, human immunodeficiency virus, autoimmune diseases, and paraproteinemia. Kidney biopsy disclosed MN with negative phospholipase A2 receptor (PLA2R) staining, favoring a secondary form of MN. Computed tomography detected a 7.6-cm duodenal schwannoma. Elective surgical resection was performed. Pathologic study showed that THSD7A (thrombospondin type 1 domain-containing 7A) was positive in both glomeruli and schwannoma. Commonly, secondary MN is related to underlying conditions, including lupus, hepatitis, and neoplasm, and can be medication induced. The risk for developing a concomitant neoplasm among patients with PLA2R-negative MN is up to 12 times higher than in the general population. Most of these neoplasms are malignancies, and the presence of autoantibodies directed at similar tissue targets is hypothesized as the potential mechanism. In our case, THSD7A may be the a...

Conclusion: Serum GGT level was a significant predictor of subsequent risk of diabetes mellitus, which increased by 4% for every 1 IU/L increase in GGT when GGT was less than 24 IU/L. PMID: 32215009 [PubMed]

In this study, we aimed to evaluate the influence of insulin production on immune system after the onset of diabetes, and we showed that the duration of honeymoon period could be related to the onset of other autoimmune conditions. For this retrospective study, 159 children aged between 11 and 18 years with type 1 DM were eligible. They have been diagnosed diabetes at least 10 years ago and use exogenous insulin. Our results showed that younger age at the onset of Type 1 DM in children, predicts Celiac Disease. Female sex and low HCO3 levels at the onset of DM had a high predictive value on patients who did not experience ...

Serious Complication of Anticoagulation in Vessel Thrombosis-associated Behçet Disease. Intern Med. 2020 Mar 26;: Authors: Ouchi K, Narui R, Sakuma T, Ojiri H Abstract Anticoagulation in venous thrombosis associated with Behçet disease (BD) is controversial. We herein report a 47-year-old woman with vessel thrombosis and pulmonary artery aneurysm (PAA) associated with BD who died of massive hemoptysis under oral anticoagulant. Although she was initially diagnosed with oral contraceptive-induced venous thromboembolism, a subsequent investigation led to a diagnosis of BD. Follow-up computed...

Abstract Brazil has reported an increase in the incidence of both gestational and congenital syphilis, posing a serious public health problem in the country. The study aimed to analyze the relationship between the supply of syphilis diagnosis and treatment in primary care and the incidence rates of gestational and congenital syphilis. An ecological study analyzed these incidence rates and the coverage of diagnostic and therapeutic measures in primary care. The study sample consisted of municipalities (counties) with population over 20,000, with coverage by primary care over 50%, and where the majority of the teams...

Downregulated miR-203 attenuates IL-β, IL-6, and TNF-α activation in TRAF6-treated human renal mesangial and tubular epithelial cells. Int J Clin Exp Pathol. 2020;13(2):324-331 Authors: Zhang L, Zhang X Abstract Circulating microRNAs (miRNAs) are attracting major interest as novel non-invasive biomarkers for human autoimmune diseases including lupus nephritis (LN). A previous study showed that altered miR-203 expression may provide highly diagnostic for systemic lupus erythematosus. However, whether miR-203 is a diagnostic biomarker for LN is still unknown. In the present research, serum sa...

CONCLUSION: Clinicians should consider the possibility of SPN for pancreatic heterogeneous masses. Multiple diagnostic imaging modalities and EUS-FNA may contribute to the preoperative diagnosis of this disease. PMID: 32211105 [PubMed]

CONCLUSION: PET/CT is a useful tool in the evaluation of colorectal cancer, and it allows to metabolically characterize undetermined lesions suspected for recurrence of disease, to perform a complete pre-surgical staging and to identify occult metastatic disease. PET/CT should be considered an essential diagnostic tool in the management of patients with colorectal cancer, especially in the preoperative staging.

CONCLUSIONS: There is no single absolute modality for de tecting ALNMs in breast cancers to replace sentinel lymph node biopsy or axillary lymph node dissection. If ALNM is suspected based on PET/CT, axillary lymph node dissection without sentinel lymph node biopsy might be a better option because it is related to high possibilities of ALNM.
