A 53-Year-Old Man with Persistent Epigastric Pain.

AbstractMorning Report is a time-honored tradition where physicians-in-training present cases to their colleagues and clinical experts to collaboratively examine an interesting patient presentation. The Morning Report section seeks to carry on this tradition by presenting a patient's chief concern and story, inviting the reader to develop a differential diagnosis and discover the diagnosis alongside the authors of the case. This report examines the story of a 53-year-old man who had epigastric pain that he described as a sensation of burning behind his sternum.

Mucormycosis and Cryptococcosis with Gastrointestinal Involvement in a Patient with Poorly Managed Diabetes.

Mucormycosis and cryptococcosis are invasive fungal infections that mostly infect immunocompromised patients and are associated with high mortality rates. Here, we report a case of a 54-year-old male with poorly controlled diabetes mellitus who was initially admitted with a complaint of right frontal headache and vomiting for 5 days. The patient was found to have paranasal sinuses mucormycosis, and later developed gastrointestinal cryptococcosis.

The Pitfall of White Blood Cell Cystine Measurement to Diagnose Juvenile Cystinosis.

Cystinosis is an autosomal recessive lysosomal storage disease, caused by mutations in the CTNS gene, resulting in multi-organ cystine accumulation. Three forms of cystinosis are distinguished: infantile and juvenile nephropathic cystinosis affecting kidneys and other organs such as the eyes, endocrine system, muscles, and brain, and adult ocular cystinosis affecting only the eyes. Currently, elevated white blood cell (WBC) cystine content is the gold standard for the diagnosis of cystinosis.

Brunner's glands hamartoma with pylorus obstruction: a case report and review of literature.

Proliferative lesions of the Brunner's glands are uncommonly encountered lesions of the small intestine, originating from the deeply seated mucosal and submucosal Brunner's glands, mainly in the duodenum. The vast majorities of these lesions are benign and include Brunner's glands hyperplasia (adenomas/nodules) and hamartomas. The etiology and pathogenesis of these lesions are not fully understood, and the diagnosis can sometimes be challenging.

Methods: Protocol duodenal graft biopsies in 27 consecutive pancreas transplants (10 simultaneous pancreas kidney [SPK], 17 pancreas after kidney [PAK]) with a follow-up of a minimum of 12 months were performed at days 14, 30, 90, 180, 360, 430.

Alport's syndrome with focal segmental glomerulosclerosis lesion - Pattern to recognize.

The association between Alport's syndrome (AS) and focal segmental glomerulosclerosis (FSGS) in the same patient is complex and rarely reported. We report a case of a 42-year-old male presenting with proteinuria, microscopic hematuria, elevated serum creatinine and hypertension with unremarkable physical examination apart from obesity. The renal biopsy showed well-established FSGS pattern of injury with mild interstitial fibrosis and tubular atrophy, while the electron microscopic examination demonstrated glomerular basement membranes (GBM) changes compatible with AS.

Testosterone- and Cortisol-secreting Oncocytic Adrenocortical Adenoma in the Pediatric Age-group.

Oncocytic tumors are epithelial neoplasms that occur in various organs, including adrenal glands. Oncocytic adrenocortical adenomas and carcinomas are uncommon but well-known pathological entities in adults. However, generally oncocytic tumors, particularly in the adrenal glands, are very rare in the pediatric age-group.

Atypical antiglomerular basement membranes disease with nephrotic-range proteinuria, mesangial proliferation, and membranoproliferative glomerulonephritis pattern of injury.

Antiglomerular basement membrane (anti-GBM) disease is an uncommon autoimmune disease characterized by the presence of IgG autoantibodies targeting the alpha-3 chain of type IV collagen. Some of the atypical forms of the disease have been described. Herein, we describe a case of atypical anti-GBM in a 27-year-old Saudi male who presented with lower limb edema, gross hematuria, elevated serum creatinine concentration, and nephrotic-range proteinuria.

Histopathology of Middle East respiratory syndrome coronovirus (MERS-CoV) infection - clinicopathological and ultrastructural study.

Aims: The pathogenesis, viral localization and histopathological features of Middle East respiratory syndrome - coronavirus (MERS-CoV) in humans are not described sufficiently. The aims of this study were to explore and define the spectrum of histological and ultrastructural pathological changes affecting various organs in a patient with MERS-CoV infection and represent a base of MERS-CoV histopathology.

Methods And Results: We analysed the post-mortem histopathological findings and investigated localisation of viral particles in the pulmonary and extrapulmonary tissue by transmission electron microscopic examination in a 33-year-old male patient of T cell lymphoma, who acquired MERS-CoV infection.

Diminished accuracy of biomarkers of fibrosis in low replicative chronic hepatitis B.

Background: We evaluated the diagnostic accuracy of aspartate aminotransferase (AST)-to-platelet ratio index (APRI), fibrosis-4 index (FIB-4), AST/alanine aminotransferase (ALT) ratio (AAR), and age-platelet index (API) for significant fibrosis (Metavir F2-4) in low-replicative (HBV DNA <20,000 IU/mL) chronic hepatitis B virus (HBV) patients.

Methods: The sensitivity, specificity, and area under the receiver-operating characteristic curve (AUROC) of HBeAg-negative, low-replicative (n = 213) and high-replicative (HBV DNA ≥20,000 IU/mL, n = 153) patients was assessed.

Results: Overall, 113 patients (30.

Collagenofibrotic (Collagen Type III) glomerulopathy in association with diabetic nephropathy.

Collagenofìbrotic (collagen type III) glomerulopathy (CG) is a rare nonimmune-mediated glomerular disease. It is characterized by massive deposition of organized collagen type III fibers, which is localized in the mesangial and subendothelial glomerular areas and associated with increased serum levels of procollagen type III peptide. Association with systemic diseases and malignancies is extremely rare.

Rare genetic variant in the CFB gene presenting as atypical hemolytic uremic syndrome and immune complex diffuse membranoproliferative glomerulonephritis, with crescents, successfully treated with eculizumab.

Background: Complement factor B gene (CFB) is an important component of the alternate pathway of complement activation that provides an active subunit that associates with C3b to form the C3 convertase, which is an essential element in complement activation. Among the complement-associated disorders, mutations and pathogenic variants in the CFB gene are relatively rare phenomena. Moreover, mutated CFB affiliation with immune-complex diffuse membranoproliferative glomerulonephritis (IC-MPGN) and atypical hemolytic uremic syndrome (aHUS) are considered a highly rare occurrence.

Biopsy-Proven BK Virus-Associated Nephropathy: Clinico-Pathologic Correlations.

Objectives: Our objective was to study the clinico-pathologic correlations in BK virus nephropathy.

Materials And Methods: We conducted a retrospective study of all patients with biopsy-proven polyoma (BK) virus infection. We compared their survival and renal outcomes versus BK virus-negative patients with biopsy-proven graft rejection.

Treatment of Light Chain Deposition Disease Using Bortezomib-Based Regimen Followed by Thalidomide-Based Regimen in a Saudi Male.

Light chain deposition disease (LCDD) is a rare illness with, as yet, no clear evidence-based guidelines for its treatment. To the best of our knowledge, LCDD has not been previously reported from Saudi Arabia. We present in this report, a 38-year-old Saudi male who presented with clinical features suggestive of hypertensive nephropathy but kidney biopsy later revealed the diagnosis of LCDD.

Magnetic Fluorescent Nanoformulation for Intracellular Drug Delivery to Human Breast Cancer, Primary Tumors, and Tumor Biopsies: Beyond Targeting Expectations.

We report the development of a chemotherapeutic nanoformulation made of polyvinylpyrrolidone-stabilized magnetofluorescent nanoparticles (Fl-PMNPs) loaded with anticancer drugs as a promising drug carrier homing to human breast cancer cells, primary tumors, and solid tumors. First, nanoparticle uptake and cell death were evaluated in three types of human breast cells: two metastatic cancerous MCF-7 and MDA-MB-231 cells and nontumorigenic MCF-10A cells. While Fl-PMNPs were not toxic to cells even at the highest concentrations used, Dox-loaded Fl-PMNPs showed significant potency, effectively killing the different breast cancer cells, albeit at different affinities.

Herb-induced acute bone marrow intoxication and interstitial nephritis superimposing glomerular C1q deposition in a patient with paroxysmal nocturnal hemoglobinuria.

Paroxysmal nocturnal hemoglobinuria is a rare disease of the red blood cell membrane that renders it lyzable by the complement system, leading to chronic intravascular hemolysis. Renal hemosiderosis is a well-known complication of intravascular hemolytic anemia and can lead to acute kidney injury and renal failure. The use of herbal medicine is common worldwide.

Salvaging of severely ruptured living-related renal allograft secondary to acute antibody mediated rejection.

Introduction: Spontaneous renal allograft rupture (RAR) is a serious and potentially life-threatening complication of kidney transplantation. Debate on the management of RAR has focused on graft nephrectomy versus salvaging in cases where: the allograft rupture site is surgically manageable; the bleeding can be controlled; and/or leaving the renal allograft in situ does not compromise patient survival.

Presentation Of Case: A 45-year-old, living-related, female, kidney allograft recipient experienced RAR on the fourth day post transplantation.

Urinary bladder radiotherapy-related chondroblastic osteosarcoma: Rare case report and review of literature.

Radiation-related osteosarcomas are well described malignant mesenchymal neoplasms, yet their pathogenesis is not fully understood. They are generally classified into either skeletal osteosarcomas, or their and rare soft tissue counterpart. The occurrence of osteosarcoma in the urinary bladder (UB) following radiotherapy is exceedingly rare.

Acute diffuse proliferative post-infectious glomerulonephritis in renal allograft--a case report and literature review.

PVN is a well-known cause of renal allograft dysfunction and failure. The diagnosis is established by examination of tissue from the renal graft, and confirmed by immunohistochemical or in situ hybridization techniques. Electron microscopy can be utilized as an ancillary modality to identify the viral particles ultrastructurally.

Predictors of significant fibrosis in chronic hepatitis B patients with low viremia.

Background And Aim: The data on the prevalence and predictors of significant fibrosis (≥F2, METAVIR) in chronic hepatitis B virus (HBV) patients with low viremia are limited. We aimed to assess both the prevalence predictors of ≥F2 fibrosis in hepatitis B envelope antigen-negative patients with HBV DNA <20,000 IU/mL.

Methods: Hepatitis B envelope antigen-negative patients (n=213) with mean HBV DNA <2000 IU/mL (n=97) and HBV DNA 2000 to 20,000 IU/mL (n=116) were included and all had liver biopsy.
