Genetic susceptibility to therapy-related leukemia after Hodgkin lymphoma or non-Hodgkin lymphoma: role of drug metabolism, apoptosis and DNA repair
Neurofibromatosis type 1 is a complex, multi-system genetic disorder that associated with an increased prevalence of pheochromocytoma and paraganglioma compared to the general population, 1.0%–5.7% versus 0.2%–0.6%, respectively. A delay in diagnosis or undiagnosed paraganglioma, as seen normotensive asymptomatic patients, may portend significant morbidity mortality risk due excess catecholamine secretion. Currently, there are no generally accepted guidelines screening for paragangliomas...
Breast cancer rarely metastasizes to the muscles, and it is even more unusual for this phenomenon result in airway compromise. We present a unique case of an 84-year-old female who presented with neck swelling upper obstruction due metastatic breast invading sternocleidomastoid muscles. After establishing diagnosis discussing possible treatment options, patient elected antiestrogen therapy, palliative tracheostomy, radiation hospice services.
Mixed connective tissue disease (MCTD) is a rare disorder with clinical features that overlap systemic lupus erythematous, sclerosis, and polymyositis. We report the case of patient who presented dysphagia, 25-lb weight loss, difficulty opening her mouth, joint pain. Dysphagia workup showed normal barium swallow normal-appearing EGD but esophageal manometry consistent severe dysmotility. Through further laboratory imaging studies, met diagnostic criteria for MCTD. She had marked improvement...
INTRODUCTION: Post-transplant lymphoproliferative disorder (PTLD) is an uncommon complication after hematopoietic stem cell transplant and associated with Epstein-Barr virus infection more aggressive immunosuppressive regimens. PTLD can coincide graft versus host disease (GVHD) mimic other disorders making endoscopic tissue sampling central to diagnosis treatment. CASE DESCRIPTION/METHODS: A 27-year-old male was admitted for worsening diarrhea undergoing umbilical cord blood Blastic...
t-MDS/AML is the major cause of non-relapse mortality after aHCT for hematologic malignancies. Independent contributions by pre-aHCT therapeutic exposures and aHCT-related factors (stem cell mobilization, conditioning) to risk are unknown. From 1986 2006, 2104 consecutive patients (median age: 49 yr) received NHL (n = 1029), MM 612), or HL 463), at City Hope (COH). Information regarding diagnosis was procured from medical records California Cancer Registry ensure complete capture. A...
9100 Background: HCT survivors may be at risk for FI, or experience difficulty performing activities of daily living, due to the high prevalence morbidity (including fatigue) during first year. Furthermore, FI have a significant impact on survivors’ QOL. Little information exists regarding this aspect patients’ lives, making it difficult anticipate their needs. Methods: Adult patients undergoing hematologic malignancies and healthy controls completed questionnaires examining (Pfeffer...
Introduction: Iron deficiency anemia is extremely prevalent with treatment most commonly in the form of an oral iron supplement. pill gastritis a known complication supplementation but not well recognized. This case shows direct endoscopic and pathologic evidence gastric mucosal injury due to supplementation. Case report: A 32-year-old male past medical history Barrett's esophagus presented abdominal pain, hematemesis, hematochezia. EGD showed severe esophagitis small erosions fundus without...
Introduction: Mixed connective tissue disease (MCTD) is a rare disorder with estimated incidence 2.1 per million year. It referred to as an “overlap” syndrome clinical manifestations can be mix of symptoms seen in scleroderma, polymyositis, and systemic lupus erythematous. Almost any organ system involved esophageal one the most common presentations (60-80%) therefore Gastroenterology may called exclude other etiologies disorders. Case report: A 54-year-old female presented three months...
Introduction: Bariatric surgery has become a common treatment option for obesity to prevent associated complications. This increased the use of pre-operative endoscopy exclude abnormalities prior surgery, practice especially important in symptomatic patients. We report case patient found have gastric ulcer who proceeded with Roux-en-Y bypass before surveillance could be performed. Case description: A 43 year-old female history Barrett's esophagus and was referred diagnostic EGD bariatric...
INTRODUCTION: The incidence of signet ring cell carcinoma (SRCC) has been rising and a genetic mutation in the CDH1 gene implicated hereditary form. Prognosis is highly dependent on stage at diagnosis determines management with either endoscopic resection vs gastrectomy. We present case incidentally found cells random gastric biopsies an patient without abnormalities. CASE DESCRIPTION/METHODS: A 66-year-old female hemochromatosis underwent EGD for evaluation intermittent solid food...
Introduction: Supine position is the standard for performing high-resolution manometry (HRM). However, this often poorly tolerated and does not simulate real world positioning. This study evaluated HRM in supine, 45-degree, upright (90-degree) positions to determine if there was a significant positional difference measurements final esophageal motility diagnoses. Methods: Twenty-7 patients (ages 30-67 years, 63% female) with no known disorder underwent evaluation of various symptoms. The...
Introduction: Acute fatty liver of pregnancy (AFLP) is a rare, potentially fatal cause acute failure occurring in the third trimester pregnancy. A defect acid oxidation (FAO) associated with increased risk developing AFLP, however condition may still occur absence these deficiencies. Due to rarity this condition, rate recurrence subsequent pregnancies largely unknown. Case Description/Methods: 29-year-old G1P0 female at 33 weeks gestation history hypertension presented 3 days nausea,...
Introduction: Pancreatic lesions can be diagnostically challenging which lead to extensive evaluations mitigate the risk of a missed malignancy. We present an unexpected diagnosis in patient with pancreatic mass features highly suspicious for malignancy on imaging. Case Description/Methods: A 37-year-old female history idiopathic pancreatitis presented abdominal pain. CT showed ill-defined 5.5cm arising from uncinate process associated long segment circumferential encasement and narrowing...
