    IgG4 related disease (IgG4RD) is a recently recognised condition characterised by mass forming lesions associated with storiform fibrosis, obliterative phlebitis, lymphoplasmacytic infiltrate rich in IgG4 positive plasma cells and elevated serum IgG4 levels. Although rare, mammary involvement has been reported as IgG4 related sclerosing mastitis, the morphological counterpart of a growing family of IgG4 related diseases. A total of 17 cases belonging to mass forming benign inflammatory breast lesions such as plasma cell mastitis, granulomatous lobular mastitis, non-specific mastitis and inflammatory pseudotumour were investigated as a possible member of IgG4 related sclerosing mastitis. Clinical, radiological, histopathological and immunohistochemistry findings were noted in all cases. Cases diagnosed as inflammatory pseudotumour showed all the histopathological features of IgG4RD along with increased number of IgG4 positive plasma cells and IgG4/IgG ratio >40%. However, only a few IgG4 positive cells were seen in plasma cell mastitis, granulomatous lobular mastitis and non-specific mastitis cases. These cases also did not fulfill the morphological criteria for the diagnosis of IgG4 related diseases. IgG4RD should be excluded in plasma cell rich lesions diagnosed on core biopsies by IgG4 immunostaining. This can avoid unnecessary surgery as IgG4 related diseases respond to simple and effective steroid treatment.

  2. IgG4-related hepatobiliary disease: an overview.

    2016-10-01

    IgG4-related hepatobiliary diseases are part of a multiorgan fibroinflammatory condition termed IgG4-related disease, and include IgG4-related sclerosing cholangitis (IgG4-SC) and IgG4-related hepatopathy. These diseases can present with biliary strictures and/or mass lesions, making them difficult to differentiate from primary sclerosing cholangitis (PSC) or other hepatobiliary malignancies. Diagnosis is based on a combination of clinical, biochemical, radiological and histological findings. However, a gold standard diagnostic test is lacking, warranting the identification of more specific disease markers. Novel assays - such as the serum IgG4:IgG1 ratio and IgG4:IgG RNA ratio (which distinguish IgG4-SC from PSC with high serum IgG4 levels), and plasmablast expansion to recognize IgG4-SC with normal serum IgG4 levels - require further validation. Steroids and other immunosuppressive therapies can lead to clinical and radiological improvement when given in the inflammatory phase of the disease, but evidence for the efficacy of treatment regimens is limited. Progressive fibrosclerotic disease, liver cirrhosis and an increased risk of malignancy are now recognized outcomes. Insights into the genetic and immunological features of the disease have increased over the past decade, with an emphasis on HLAs, T cells, circulating memory B cells and plasmablasts, chemokine-mediated trafficking, as well as the role of the innate immune system.

    IgG4-related disease is a newly recognized fibroinflammatory disorder that has the ability to affect nearly every organ system. It is characterized by tumefactive lesions and fibrosis and closely mimics neoplasms. Only one case of IgG4-related bladder mass has been reported in the literature, but there are no reports of IgG4-related disease in a urachal mass. Herein, we report a 26-year-old male who initially presented with symptoms of recurrent UTI. Work-up revealed a 6 cm urachal tumor, a 1.4 cm pulmonary lesion, and mediastinal lymphadenopathy; all metabolically active on PET scan and suspicious for urachal adenocarcinoma. Lung lesion fine needle aspiration and TURBT pathology revealed inflammation but no evidence of malignancy. The patient underwent a partial cystectomy and umbilectomy with pathology demonstrating dense plasmacytic cells, a high rate of immunohistochemistry staining positive for IgG4 plasma cells, a storiform pattern of fibrosis, and an obliterative phlebitis. Furthermore, the patient had an elevated serum IgG4 level of 227 mg/dL (range 2.4-121 mg/dL). IgG4-related disease is a newly recognized fibroinflammatory disorder that can mimic neoplastic processes and a high index of suspicion and accurate tissue pathology is necessary for an accurate diagnosis.

    IgG4-related disease is a relatively new disease entity characterized by elevated serum IgG4 levels and marked infiltration of IgG4-positive plasma cells in lesions. Organ enlargement or nodular lesions consisting of abundant infiltration of lymphocytes and IgG4-positive plasma cells and fibrosis are seen in various organs throughout. We encountered a patient with an inflammatory pseudotumor of the rectum, which was histopathologically confirmed to be an IgG4-related disease. The patient was a 28-year-old woman who had constipation for 3 months. The endoluminal ultrasonography showed a lesion that was heterogeneous and low echogenic in lower rectum. The result of colonoscopic biopsy findings was of chronic proctitis with lymphoid aggregates. For a confirmative diagnosis, excision was performed. Histopathological examination represented plasma cell infiltration and fibrosis. Immunohistochemistry revealed prominence of IgG4-positive plasma cells and confirmed the diagnosis of IgG4-related disease. The patient is currently under observation on low-dose oral prednisolone without relapse. PMID:27186575

    IgG4-related disease (IgG4-RD) is a systemic inflammatory disorder that can affect most organs/tissues like sarcoidosis. The kidney is one of the most frequently affected organs. While tubulointerstitial nephritis (TIN) with characteristic imaging findings is the representative lesion of IgG4-related kidney disease (IgG4-RKD), a variety of glomerular lesions, particularly membranous nephropathy, sometimes overlap on TIN. Clinically, either decreased renal function and/or characteristic imaging findings such as multiple low-density lesions on contrast-enhanced computed tomography are typical presenting features. Histologically, plasma cell (PC)-rich TIN accompanied by characteristic fibrosis called storiform fibrosis with dense IgG4-positive PC infiltration is a typical finding. Although a swift response to corticosteroid is a very important feature of IgG4-RKD, in cases with moderately to severely decreased renal function before therapy, only partial recovery of renal function is obtained. This review provides a comprehensive overview of IgG4-RKD from the clinical, laboratory, imaging, and histological aspects and also addresses some of the therapeutic issues concerning it.

  6. Autoimmune pancreatitis and IgG4-related systemic diseases

    2010-01-01

    Autoimmune pancreatitis (AIP) is a rare form of chronic pancreatitis that is characterized by lymphoplasmacytic infiltrate, storiform fibrosis, obliterative phlebitis, and increased IgG4+ plasma cells. Serum IgG4 levels usually are elevated. Patients with AIP frequently have disease affecting other organs or sites; these tissues show similar histologic changes, including increased IgG4+ plasma cell infiltrate and response to corticosteroid therapy. A new clinicopathologic concept of IgG4-related systemic disease (ISD) has been proposed. These diseases often are not limited to the pancreas, and the pancreas may not be involved at all. In this article, we review the literature and our own experience to detail the clinicopathologic features of AIP and extrapancreatic lesions in ISD. PMID:20606730

    Abstract Objectives: IgG4-related disease (IgG4-RD) is an immune-mediated fibroinflammatory condition that can affect multiple organs and lead to tumefactive, tissue-destructive lesions. Reports have described inflammatory aortitis and periaortitis, the latter in the setting of retroperitoneal fibrosis (RPF), but have not distinguished adequately between these 2 manifestations. The frequency, radiologic features, and response of vascular complications to B cell depletion remain poorly defined. We describe the clinical features, radiology findings, and treatment response in a cohort of 36 patients with IgG4-RD affecting large blood vessels. Methods: Clinical records of all patients diagnosed with IgG4-RD in our center were reviewed. All radiologic studies were reviewed. We distinguished between primary large blood vessel inflammation and secondary vascular involvement. Primary involvement was defined as inflammation in the blood vessel wall as a principal focus of disease. Secondary vascular involvement was defined as disease caused by the effects of adjacent inflammation on the blood vessel wall. Results: Of the 160 IgG4-RD patients in this cohort, 36 (22.5%) had large-vessel involvement. The mean age at disease onset of the patients with large-vessel IgG4-RD was 54.6 years. Twenty-eight patients (78%) were male and 8 (22%) were female. Thirteen patients (36%) had primary IgG4-related vasculitis and aortitis with aneurysm formation comprised the most common manifestation. This affected 5.6% of the entire IgG4-RD cohort and was observed in the thoracic aorta in 8 patients, the abdominal aorta in 4, and both the thoracic and abdominal aorta in 3. Three of these aneurysms were complicated by aortic dissection or contained perforation. Periaortitis secondary to RPF accounted for 27 of 29 patients (93%) of secondary vascular involvement by IgG4-RD. Only 5 patients demonstrated evidence of both primary and secondary blood vessel involvement. Of those treated with

    IgG4-related disease (IgG4-RD) is a recently recognized group of conditions, characterized by tumor-like swelling of involved organs, lymphoplasmacytic infiltrate rich in IgG4-positive plasma cells, variable degrees of fibrosis, and elevated serum IgG4 concentrations. Currently IgG4-RD is recognized as a systemic condition that can affect several organs and tissues. Herein we report the case of a 34-year-old male patient who was admitted to our hospital with diffuse abdominal pain, weight loss, and painful stiffness in his neck. He had a history of tumoral mass of the left maxillary region, right palpebral ptosis with protrusion of the eyeball, and chronic dry cough for about 6 years. Laboratory tests revealed polyclonal hypergammaglobulinemia and increased serum IgG4 levels. Immunohistochemical staining of the maxillary biopsy was compatible with IgG4-RD. He had an excellent response to corticosteroid therapy. This case highlights that IgG4-RD should be included in the differential diagnosis with multisystem diseases. PMID:25506457

    Abstract To review the reported evidence on the therapeutic management of IgG4-related disease (IgG4-RD) in clinical practice. A systematic search of the literature was conducted. The primary outcome measured was the rate of efficacy of first-line therapeutic approaches. Secondary outcomes measured included the rate of disease relapse, the outcome of untreated patients, the rate of patients without drug therapy at the end of follow-up, the rate of side effects, and mortality. The MOOSE, AHRQ, STROBE, and GRACE recommendations/statements were followed. The results of the systematic search strategy yielded 62 studies that included a total of 3034 patients. Complete information about first-line therapeutic regimens was detailed in 1952 patients, including glucocorticoid-based regimens in 1437 (74%), drug-free regimens in 213 (11%), and other therapies in 38 (2%). No therapy (wait and see management) was reported in 264 (13%) patients. The efficacy of monotherapy with glucocorticoids was specified in 1220 patients, of whom 97% had a therapeutic response. Relapses, however, were reported in 464/1395 (33%) patients despite typically short follow-up periods. Therapeutic efficacy was reported in 219/231 (95%) of relapses treated with glucocorticoids, 56/69 (81%) of those treated with azathioprine, 16/22 (72%) of those treated with other immunosuppressive agents, and in the 9 cases treated with rituximab (100%). In 14 studies, the authors detailed the outcome of 159/246 patients with wait-and-see management; spontaneous improvement or resolution was reported in 68 (43%) cases. Wide heterogeneity was observed with respect to the first-line therapeutic approaches used for the different organ-specific disease subsets, including significant differences in the mean dose of glucocorticoids used. Nearly 70% of reported IgG4-RD patients are treated with oral glucocorticoids in monotherapy. However, the therapeutic management is heavily influenced by geographical, epidemiological

    Intrathoracic involvement of immunoglobulin G4 (IgG4)-related disease has recently been reported. However, a subset of the disease presenting as interstitial lung disease is rare. Here, we report a case of a 35-year-old man with IgG4-related lung disease with manifestations similar to those of interstitial lung disease. Chest computed tomography showed diffuse ground glass opacities and rapidly progressive pleural and subpleural fibrosis in both upper lobes. Histological findings showed diffuse interstitial lymphoplasmacytic infiltration with an increased number of IgG4-positive plasma cells. Serum levels of IgG and IgG4 were also increased. The patient was diagnosed with IgG4-related lung disease, treated with anti-inflammatory agents, and showed improvement. Lung involvement of IgG4-related disease can present as interstitial lung disease and, therefore, should be differentiated when evaluating interstitial lung disease.

    Recent studies suggested the existence of two subtypes of autoimmune pancreatitis (AIP): type 1 related with IgG4 (lymphoplasmacytic sclerosing pancreatitis; LPSP) and type 2 related with a granulocytic epithelial lesion (idiopathic duct-centric chronic pancreatitis; IDCP). Apart from type 2 AIP, the pathological features of type 1 AIP with increased serum IgG4/IgE levels, abundant infiltration of IgG4+ plasmacytes and lymphocytes, fibrosis, and steroid responsiveness are suggestive of abnormal immunity such as allergy or autoimmunity. Moreover, the patients with type 1 AIP often have extrapancreatic lesions such as sclerosing cholangitis, sclerosing sialadenitis, or retroperitoneal fibrosis showing similar pathological features. Based on these findings, many synonyms have been proposed for these conditions, such as "multifocal idiopathic fibrosclerosis", "IgG4-related autoimmune disease", "IgG4-related sclerosing disease", "IgG4-related plasmacytic disease", and "IgG4-related multiorgan lymphoproliferative syndrome", all of which may refer to the same conditions. Therefore, the Japanese Research Committee for "Systemic IgG4-related Sclerosing Disease" proposed a disease concept and clinical diagnostic criteria based on the concept of multifocal fibrosclerosis in 2009, in which the term "IgG4-related disease" was appointed as a minimal consensus on these conditions. Although the significance of IgG4 in the development of "IgG4-related disease" remains unclear, we have proposed a hypothesis for the development of type 1 AIP, one of the IgG4-related disease. The concept and diagnostic criteria of "IgG4-related disease" will be changed in accordance with future studies. PMID:21170607

    Immunoglobulin G4-related disease (IgG4-RD) is a fibroinflammatory condition that derives its name from the characteristic finding of abundant IgG4+ plasma cells in affected tissues, as well as the presence of elevated serum IgG4 concentrations in many patients. In contrast to fibrotic disorders, such as systemic sclerosis or idiopathic pulmonary fibrosis in which the tissues fibrosis has remained largely intractable to treatment, many IgG4-RD patients appear to have a condition in which the collagen deposition is reversible. The mechanisms underlying this peculiar feature remain unknown, but the remarkable efficacy of B cell depletion in these patients supports an important pathogenic role of B cell/T cell collaboration. In particular, aberrant T helper type 2 (Th2)/regulatory T cells sustained by putative autoreactive B cells have been proposed to drive collagen deposition through the production of profibrotic cytokines, but definitive demonstrations of this hypothesis are lacking. Indeed, a number of unsolved questions need to be addressed in order to fully understand the pathogenesis of IgG4-RD. These include the identification of an antigenic trigger(s), the implications (if any) of IgG4 antibodies for pathophysiology and the precise immunological mechanisms leading to fibrosis. Recent investigations have also raised the possibility that innate immunity might precede adaptive immunity, thus further complicating the pathological scenario. Here, we aim to review the most recent insights on the immunology of IgG4-RD, focusing on the relative contribution of innate and adaptive immune responses to the full pathological phenotype of this fibrotic condition. Clinical, histological and therapeutic features are also addressed. PMID:25865251

    IgG4-related disease is a recently recognized entity linked initially to autoimmune pancreatitis and has been subsequently described in nearly every organ system. Men over the age of 50 represent the most affected demographic group and a comprehensive set of diagnostic criteria has been developed to aid treating clinicians. Though elevated levels of IgG4 in the serum are suggestive of the disease, definitive diagnosis is made on histopathology. Treatment is tailored to the clinical presentation with corticosteroid therapy known to have proven efficacy. Gastric manifestations of the IgG4-related disease primarily come in two varieties, notably chronic ulceration or pseudotumor formation. Autoimmune pancreatitis conveys increased risk for IgG4-related disease of the stomach, which is independent of Helicobacter pylori status. In this case report, we present an acute gastric-pericardial fistula secondary to IgG4-related disease that required urgent operative management. To our knowledge, this is the first report in the medical literature describing this complication of IgG4-related disease. PMID:25469052

    We experienced severe asthmatic crisis during general anesthesia in a 45-year-old man with IgG4-related disease, COPD and athma undergoing removal of submandibular gland. The ventilatiory failure was caused by the stimulation of the operation, sputum, and neostigmine. His serum IgG4 level was extremely high. IgG4 related disease is a recently emerging entity characterized by a diffuse or mass forming inflammatory reaction rich in IgG4-positive plasma cells associated with fibrosclerosis and obliterative phlebitis. It is associated with an elevated serum level of IgG4 and an allergic disease. We must be careful in perioperative management of the patients with IgG4-related disease because general anesthesia can induce asthmatic crisis. PMID:24783608

    Introduction IgG4-related disease (IgG4-RD) is a fibroinflammatory disorder that may involve almost each organ or system. IgG4-related kidney disease (IgG4-RKD) refers to renal lesions associated with IgG4-RD. The most frequent morphological type of renal lesions is IgG4-related tubulointerstitial nephritis (IgG4-TIN) which is associated with increased IgG4-positive plasma cell infiltration and interstitial fibrosis. Case Report Herein, we present a rare case with coexisting IgG4-RKD and acute crescent glomerulonephritis with concomitant severe tubulointerstitial lesions instead of classic IgG4-TIN. Conclusion IgG4-RKD and acute crescent glomerulonephritis can occur in the same patient. This case may give us a clearer viewpoint of the disease. PMID:27504450

Herein, we report the case of a 74-year-old man with IgG4-related disease of lung and pleura, clinically suspicious of malignant mesothelioma. Chest computed tomography showed diffuse nodular pleural thickening, and microscopic finding disclosed diffuse thickening of visceral pleura with infiltrations of many lymphoplasma cells with increased number of IgG4-positive plasma cells and a few multinucleated giant cells. It is important for pathologists and clinicians to recognize this rare entity and its histologic finding, because it can be confused with malignant tumors on the radiologic examination although it can be treated with steroid therapy.

    IgG4-related disease (IgG4-RD) may involve multiple organs. Although it usually presents as diffuse organ involvement, localized mass-forming lesions have been occasionally encountered in pancreas. However, the same pattern has been seldom reported in biliary tract. A 61-year-old male showed a hilar bile duct mass with multiple enlarged lymph nodes in imaging studies and he underwent trisectionectomy under impression of cholangiocarcinoma. Gross examination revealed a mass-like lesion around hilar bile duct. Histopathologically, dense lymphoplasmacytic infiltration and storiform fibrosis were identified without evidence of malignancy. Immunohistochemical stain demonstrated rich IgG4-positive plasma cell infiltration. Follow-up imaging studies disclosed multiple enlarged lymph nodes with involvement of pancreas and perisplenic soft tissue. The lesions have been significantly reduced after steroid treatment, which suggests multi-organ involvement of systemic IgG4-RD. Here, we report an unusual localized mass-forming IgG4-related cholangitis as an initial presentation of IgG4-RD, which was biliary manifestation of systemic IgG4-related autoimmune disease.

    Having the characteristic features of elevated serum IgG4 levels and prominent infiltration of IgG4-positive plasma cells with fibrosis in lesions, Mikulicz's disease (MD) has been recognized as an IgG4-related disease (IgG4-RD). Although incidence of autoimmune pancreatitis (AIP), one of the organ characteristics of IgG4-RD, has been internationally reported, there are only a few such reports of IgG4-related MD. The limited number of reports might be attributable to the low recognition of IgG4-related MD as a clinical entity as well as its misdiagnosis as Sjögren's syndrome (SS). Thus, we compared several clinical features of MD with SS to improve proper clinical diagnosis of MD in the clinical setting. A total of 70 SS and 70 MD cases evaluated at Sapporo Medical University Hospital were retrospectively analyzed. In SS patients, sicca symptoms were the most frequent (87%), followed by articular symptoms (23%), while lacrimal and salivary gland swelling were a rare (10%) and transient manifestation. In contrast, lacrimal or salivary gland swelling was observed in all patients with MD. Although nearly 60% of MD patients complained of sicca syndrome, skin rash and arthralgia were rare symptoms. Hypergammaglobulinemia was recognized in both SS and MD patients, but the occurrence of autoantibodies in patients with IgG4-related MD was low. Extraglandular organ involvement, often involving the retroperitoneum, pancreas, kidney and lung, was often discovered at the time of IgG4-related MD diagnosis. Although corticosteroid therapy tended to delay the hypofunction of salivary gland in SS patients, recovery of decreased function of salivary glands were observed in IgG4-related MD patients. These results suggest the beneficial effect of aggressive corticosteroid intervention in patients with IgG4-related MD. Although SS and MD are both chronic inflammatory diseases affecting the lacrimal and salivary glands, their clinical features and corticosteroid responsiveness are

    Hashimoto's thyroiditis (HT) has been characterized for many years as a well-defined clinicopathologic entity, but is now considered a heterogeneous disease. IgG4-related HT is a new subtype characterized by thyroid inflammation rich in IgG4-positive plasma cells and marked fibrosis. It may be part of the systemic IgG4-related disease. We report a case of a 56-year-old Portuguese man who presented with a one-month history of progressive neck swelling and dysphagia. Laboratory testing revealed increased inflammatory parameters, subclinical hypothyroidism and very high levels of thyroid autoantibodies. Cervical ultrasound (US) demonstrated an enlarged and heterogeneous thyroid gland and two hypoechoic nodules. US-guided fine needle aspiration cytology was consistent with lymphocytic thyroiditis. The patient was submitted to total thyroidectomy and microscopic examination identified typical findings of HT, marked fibrosis limited within the thyroid capsule and lymphoplasmacytic infiltration, with >50 IgG4-positive plasma cells per high-power field and an IgG4/IgG ratio of >40%. After surgery, serum IgG4 concentration was high-normal. Symptoms relief and reduction in laboratory inflammatory parameters were noticed. Thyroid function is controlled with levothyroxine. To our knowledge we report the first case of IgG4-related HT in a non-Asian patient. We also perform a review of the literature regarding IgG4-related disease and IgG4-related HT. Our case highlights this new variant of the well known HT, and helps physicians in recognizing its main clinical features, allowing for proper diagnosis and treatment. PMID:25465611

Here we reported the case of a 24-year-old woman with IgG4-related lung disease. This patient presented with fever, cough and shortness of breath. Thoracic computed tomography (CT) images demonstrated multiple nodules or masses with high density in both lungs, and thickened interlobular septa. The ‘halo sign’ was observed around the high-density lesions of the upper lobes. This range of CT images’ characteristics is atypical, which differs from previous reports of this condition.

    This report describes a case of reversible topiramate-induced maculopathy in a 32-year-old female patient with IgG4-related disease. The patient presented with decreased vision associated with anterior uveitis and cystoid macula edema, which was unresponsive to oral and topical steroids. Following topiramate cessation, both cystoid macula edema and vision improved. The ocular side effects of topiramate and putative pharmacological mechanisms for topiramate-induced maculopathy in the context of IgG4-related disease are discussed. This report highlights that neurologists and ophthalmologists should be aware that patients presenting with topiramate-associated maculopathy should be advised to discontinue topiramate promptly to prevent irreversible loss of vision.

    Hypophysitis is a rare inflammatory disorder that can mimic a pituitary tumor clinically or radiologically. Furthermore, immunoglobulin G4 (IgG4)-related systemic disease is only a just recently characterized disorder. It can manifest as a systemic disease involving multiple organs, including the pancreas, salivary glands, lungs, liver, bile duct, gallbladder, kidneys, and retroperitoneum. It is characterized by a high serum level of IgG4 clinically and dense lymphoplasmacytic infiltration with sclerosis and phlebitis histologically. Herein, we report the case of a man 66 years of age who presented with nausea, vomiting, and poor appetite with a body weight loss of 4 kg. Image study revealed a pituitary infundibulum mass, right-posterior mediastinal and paraspinal masses, as well as infiltrating masses in bilateral kidneys. Therefore, he received a thoracoscopic biopsy for the right-posterior mediastinal and paraspinal masses and a pathologic examination reported an IgG4-related inflammatory pseudotumor. Then, transsphenoidal removal of the infundibulum mass was performed. Histologically, the infundibulum mass represented a IgG4-related hypophysitis manifested as an infiltration of plasma cells, lymphocytes, histiocytes, and some eosinophils with a fair number of IgG4-immunoreactive plasma cells. After the operation was complete, the patient took 5 mg of prednisolone every 2 days for 3 months. A follow-up computed tomography scan revealed improvement of the infiltrating masses in the bilateral kidneys. PMID:23522762

    The pathophysiology of glomerular lesions of membranous nephropathy (MN), including seldom-reported IgG4-related disease, is still elusive. Unlike in idiopathic MN where IgG4 prevails, in this patient IgG3 was predominant in glomerular deposits in the absence of circulating anti-phospholipase A2 receptor antibodies, suggesting a distinct pathologic process. Here we documented that IgG4 retrieved from the serum of our propositus reacted against carbonic anhydrase II (CAII) at the podocyte surface. In patient's biopsy, glomerular CAII staining increased and co-localized with subepithelial IgG4 deposits along the capillary walls. Patient's IgG4 caused a drop in cell pH followed by mitochondrial dysfunction, excessive ROS production and cytoskeletal reorganization in cultured podocytes. These events promoted mitochondrial superoxide-dismutase-2 (SOD2) externalization on the plasma membrane, becoming recognizable by complement-binding IgG3 anti-SOD2. Among patients with IgG4-related disease only sera of those with IgG4 anti-CAII antibodies caused low intracellular pH and mitochondrial alterations underlying SOD2 externalization. Circulating IgG4 anti-CAII can cause podocyte injury through processes of intracellular acidification, mitochondrial oxidative stress and neoantigen induction in patients with IgG4 related disease. The onset of MN in a subset of patients could be due to IgG4 antibodies recognizing CAII with consequent exposure of mitochondrial neoantigen in the context of multifactorial pathogenesis of disease.

    Although chronic inflammatory disorders of the ocular adnexa are relatively common, their pathogenesis is in many cases poorly understood. Recent investigation suggests that many cases of sclerosing orbital inflammation are a manifestation of IgG4-related disease; however, most patients reported have been Asian, and it is not clear whether the results of studies from the Far East can be reliably extrapolated to draw conclusions about Western patients. We evaluated 38 cases previously diagnosed as orbital inflammatory pseudotumor or chronic dacryoadenitis to determine whether our cases fulfill the criteria for IgG4-RD (IgG4-related dacryoadenitis when involving the lacrimal gland, and IgG4-related sclerosing orbital inflammation when involving orbital soft tissue). Fifteen patients had IgG4-related dacryoadenitis or orbital inflammation. These patients included 9 men and 6 women, aged 24 to 77 years (median, 64 y). Lesions involved orbital soft tissue (8 cases), lacrimal gland (6 cases), and canthus (1 case). In 1 case, focal in situ follicular neoplasia was seen in a background of IgG4-RD. In another case, a clonal IGH gene rearrangement was detected. Four patients with IgG4-RD had evidence of IgG4-RD in other anatomic sites. Five patients, 1 man and 4 women, aged 26 to 74 years (median 50 y) had orbital lesions (2 involving lacrimal gland, 3 involving soft tissue) suspicious for, but not diagnostic of, IgG4-RD. Of 16 patients with IgG4-RD or probable IgG4-RD with information available regarding the course of their disease, 11 patients experienced recurrent or persistent orbital disease. However, no patient developed lymphoma, and no patient died of complications of IgG4-RD. Eighteen patients had lesions not representing IgG4-RD.

    IgG4-related disease is a recently established systemic condition. Tubulointerstitial nephritis is the most common renal manifestation. Glomerular lesions, particularly membranous glomerulonephritis, can develop simultaneously. Some patients present with serological renal dysfunction associated with elevated IgG or IgE levels and hypocomplementemia, while others are incidentally found to have abnormalities in kidneys on imaging. A majority of patients with IgG4-related kidney disease have similar lesions at other anatomical sites, which help us to suspect this condition. Serum IgG4 elevation (>135 mg/dL) is the most, although not entirely, specific marker for the diagnosis. Imaging findings varies from small nodules to bilateral diffuse abnormalities. In addition to the renal parenchyma, the renal pelvis and perirenal adipose tissue can be affected. Histological features include dense lymphoplasmacytic infiltration, storiform or "bird's eye" fibrosis (highlighted by PAM stain), and IgG4-positive plasma cell infiltration (>10 cells/high-power field and IgG4/IgG-positive cell ratio >40%). Immune complex deposition is detectable in the tubular basement membrane by immunofluorescence and/or electron microscopy. Patients usually respond well to corticosteroids, but highly active diseases may require other immunosuppressive therapies. Further investigations will be required to fully understand pathophysiology underlying this emerging condition. PMID:25337295

LC was diagnosed based on clinical presentation and pathological appearance; furthermore, combined with serological examination and immunohistochemical study, the case also conformed to the diagnosis of IgG4-RD. The IgG4-RD, broadly discussed in recent times, is an idiopathic disease entity with tissue fibrosis possibly involving multiple organs. To the best of our knowledge, IgG4-RD has never been reported with LC. By reporting the clinical course and literature review, we should pay attention to the association between these two diseases.

    The submandibular gland is one of the most frequently affected salivary gland in IgG4-related systemic disease, usually demonstrate homogeneous attenuation on CT imaging as reported, but without much pathological comparison of many cases. This article is to investigate and analyze the typical CT findings and pathologic characteristics of IgG4-related systemic disease (IgG4-RSD) of submandibular gland. A retrospective analysis of the preoperative CT findings in patients with IgG4-RSD of submandibular glands who underwent surgical resection between January 2010 and February 2014 was performed. Twenty patients (16 women) were identified, with a mean age of 58.1±10.2 years. All patients presented with painless submandibular gland swelling. Diffuse gland enlargement, with clear margins and homogeneous density, was found on non-enhanced CT scans in all cases. There were no calcifications or stones within the involved glands. Based on contrast-enhanced CT appearance the patients could be divided into two groups: 11 cases showed homogeneous gland enhancement; and multiple hyperenhancing foci, with a crazy-paving pattern, were detected in 9 cases, which were in consistent with the pathologic findings. The maximum submandibular gland diameter on transverse images was significantly larger (P=0.008) in patients with crazy-paving appearance (32±4 mm) compared to patients with homogeneous enhancement (28±3 mm). It is concluded that the submandibular glands with IgG4-RSD can be characterized by either homogenous appearance or crazy-paving pattern on contrast-enhanced CT imaging.

    Abstract Immunoglobulin-G4 (IgG4)-related disease (IgG4RD) is a fibro-inflammatory disorder characterized by tissue-infiltrating IgG4+ plasma cells, and, often, high serum IgG4. Several autoimmune, infectious, or proliferative conditions mimic IgG4RD. Erdheim-Chester disease (ECD) is a rare non-Langerhans cell histiocytosis, characterized by foamy histiocytic infiltration, fibrosis, and chronic inflammation. ECD and IgG4RD manifestations may overlap. A patient presented with huge fibrous retroperitoneal masses causing compression on neighboring structures; the case posed the challenge of the differential diagnosis between IgG4RD and ECD mainly because of a prominent serum and tissue IgG4 response. Retroperitoneal biopsy led to the diagnosis of ECD; the V600E BRAF mutation was found. Treatment with the BRAF inhibitor vemurafenib was started. Treatment failed to induce mass regression and the patient died after 3 months of therapy. Prompted by this case, we examined serum and tissue IgG4 in a series of 15 ECD patients evaluated at our center, and found that approximately one-fourth of the cases have increased IgG4 in the serum and often in the tissue. The differential diagnosis between IgG4RD and ECD can be challenging, as some ECD patients have prominent IgG4 responses. This suggests the possibility of common pathogenic mechanisms between ECD and IgG4RD. PMID:27227923

    IgG4-related disease (IgG4-RD) is a systemic disease that affects multiple organs and generates nodules or thickening. Discriminating these diseases from malignancy is important because glucocorticoid treatment is effective for patients with IgG4-RD. Coexistence of IgG4-RD with various malignant diseases has been reported, but there are few reports with regard to gynecologic malignant diseases. We encountered a case of invasive cervical cancer stage IIB accompanied by IgG4-RD. The patient was a 46-year-old woman. On pelvic magnetic resonance imaging, fluorodeoxyglucose-positron emission tomography and computed tomography, systemic multiple lymph node swelling was seen, including in the neck and the mediastinum in addition to uterine cervix. Diagnosis (and hence, appropriate treatment choice) was achieved on pathology of the submandibular gland and uterus, and analysis of serum IgG4. IgG4-RD should be suspected in patients presenting with malignancy and unusual multiple lymph node swelling. PMID:27238361

    IgG4-related disease (IgG4-RD) is a fibroinflammatory condition that can affect essentially any organ. The disease shows similar histopathology findings across organ systems, consisting of a lymphoplasmacytic infiltrate enriched in IgG4-positive plasma cells, storiform fibrosis, and obliterative phlebitis. IgG4 itself appears to be a reactive phenomenon rather than the primary disease driver. Recent investigations have focused on the interactions between cells of the B cell lineage and a novel CD4+ SLAMF7+ cytotoxic T cells capable of promoting fibrosis. Plasmablasts appear to play a crucial role along with B cells in the presentation of antigen to this T cell. IgG4-RD is marked by responsiveness to glucocorticoids, but frequent disease relapse, the inability to taper glucocorticoids completely, and steroid toxicity are problematic. Targeted treatment approaches against the B cell lineage appear promising, and therapeutic efforts focused upon the CD4+ SLAMF7+ cytotoxic T cell may also be feasible. PMID:27586808

    IgG4-related disease (IgG4RD) is a chronic recurring fibro-inflammatory pathology that is considered to be of autoimmune origin. Histopathology is considered to be the gold standard method for diagnosis. IgG4RD affects multiple organs. IgG4RD was first identified in the pancreas and was called autoimmune pancreatitis (AIP). During the following years, the disease spectrum was expanded and it was realised that the extrapancreatic lesions can precede, coexist or appear after the diagnosis of AIP. At present, several illnesses such as Mikulicz disease, Küttner tumour, multifocal fibrosclerosis, etc, are considered to be part of the IgG4RD spectrum. The symptoms of the disease tend to appear over months and years and diagnosis is achieved on average 13.5 months (4–60 months) after the onset. The purpose of this report was to provide information about a case that was sadly fatal but that permitted a complete histopathological study of the damaged tissues. PMID:23645656

    IgG4-related orbital disease is a recognised cause for orbital inflammation. As its awareness increases and diagnostic accuracy improves there will be an increased number of cases being identified. This unique case demonstrates for the first time, with histological evidence, a case of a non-lacrimal IgG4-related orbital disease with concurrent IgG4-related mastitis. We describe a 47 year old who presented with a supraorbital swelling and mass. This was initially successfully treated with oral steroids and was later excised on recurrence. Immunohistochemical and blood serum analysis confirmed IgG4-related orbital disease. On systemic enquiry she was found to have a mass of the breast, which was shown to be IgG4-related mastitis. She is currently asymptomatic with no sign of recurrence and is under long-term surveillance. This case highlights the importance of systemic work up in patients presenting with orbital foci of IgG4 disease.

    IgG4-related disease (IgG4-RD) is a recently designated disease entity and its full picture has not yet been elucidated. Here, we report an unusual case of a patient with gastric wall thickening secondary to IgG4-RD. A 68-year-old male visited our hospital with itchy skin lesions and an episode of organizing pneumonia. On the suspicion of malignancy-associated skin lesions, computed tomography (CT) was performed. The CT revealed prominent thickening of the gastric wall. Due to the possibility of malignancy, the patient underwent distal gastrectomy. Histopathological examination showed fibrosis of the submucosa and prominent thickening of the muscularis propria. Most of infiltrating cells were IgG4-positive plasma cells. Post-operative blood test revealed significantly high serum levels of total IgG and IgG4. Based on these histological features, the patient was given a definitive diagnosis of IgG4-RD. Further accumulation of cases like the present case that develop IgG4-RD with rare manifestations would lead to the elucidation of pathogenesis. PMID:26603834

    We report a case of a 71-year-old Filipino female who was admitted to the hospital for abdominal pain, vomiting and diarrhea of 8 days duration. The patient was found to have marked acute kidney injury (AKI), which required hemodialysis in the next 3 days. Extensive workup revealed hematuria, subnephrotic range proteinuria, elevated anti-nuclear antibody (ANA) and elevated total immunoglobulin G (IgG) levels, with normal IgG4 and anti-dsDNA levels. On kidney biopsy, mild membranous glomerulonephritis was found, along with autoimmune tubulointerstitial nephritis (TIN) with a “full-house” pattern of immune deposits. These findings were suggestive of lupus interstitial nephritis. However, IgG4+ plasma cells were detected in the interstitium by immunostaining, favoring a diagnosis of IgG4-related kidney disease (IgG4-RKD). Our case highlights the difficulty in differentiating lupus nephritis (LN) from IgG4-RKD in some patients, raising the suspicion that these two entities can co-exist. PMID:26015827

    Since IgG4-related pancreatitis was first reported in 2001, IgG4-related disease has been identified in other organs such as salivary gland, gallbladder, thyroid, retroperitoneum and kidney; but lung invasion is rare. A 63-year-old man presented with hemoptysis at the pulmonary clinic and chest computed tomography revealed about 4.1 cm irregular shaped mass with spiculated margin at the left upper lobe. Despite no elevation of serum IgG4 level, he was finally diagnosed as IgG4-related lung disease by transthoracic needle biopsy. After treatment with oral glucocorticoids, hemoptysis disappeared and the size of lung mass was decreased. PMID:27433179

    IgG4-related disease (IgG4-RD) is a recently recognized chronic fibrotic inflammation, which can affect almost every organ, and may come to clinical attention first due to visible organ swelling or organ dysfunction, or is identified incidentally by imaging and specific biopsy. The disorder has an allergic background and is immune-mediated. Up-regulated responses of T helper 2 and T regulatory cells and their cytokines play a major role in disease progression. About 30-50% of patients are atopic or have mild eosinophilia. IgG4-RD predominantly affects middle-aged male patients. The cornerstones of diagnosis of the disease are compatible clinical features and typical histopathology. Swelling of salivary and lacrimal glands, lymphadenopathy, and type 1 autoimmune pancreatitis (AIP) are the most common manifestations of the disease. However, other tissues and organs, such as retroperitoneum, lung, kidney, aorta, upper airways, thyroid gland, meninges, heart, mesenterium and skin may be involved. Typical histopathology is lymphoplasmacytic infiltration abundant in IgG4-positive plasma cells, storiform-type fibrosis, and obliterative phlebitis. Elevated serum IgG4 concentration supports the diagnosis. Characteristic imaging features such as a "capsule-like rim" surrounding the pancreatic lesions is highly specific to type 1 AIP. 18F-fluorodeoxyglucose positron emission tomography/computed tomography enables mapping the sites of inflammation, permits evaluation of the extent of the disease, helps in guiding biopsy decision, and may be used in monitoring response to treatment. Glucocorticoids alone or in combination with B-cell depletion with rituximab induces prompt clinical response to IgG4-RD. This article reviews the current understanding, different clinical manifestations, and approaches to diagnosis and treatment of IgG4-RD.

    Relapsing polychondritis (RP) is a rare systemic disorder characterized by recurrent, widespread chondritis of the auricular, nasal, and tracheal cartilages. IgG4-related disease (IgG4-RD) is a systemic immune-mediated disease characterized by the infiltration of IgG4-bearing plasma cells into systemic organs. Although 25% to 35% of patients with RP have a concurrent autoimmune disease, coexistence of RP and IgG4-RD is rare. We herein report a case of RP complicated by IgG4-RD. A 63-year-old man developed recurrent bilateral ear pain and swelling, recurrent blurred and decreased vision, and migratory multiple joint pain, sequentially within one year. Fourteen months after the first symptom, he experienced dry cough and dyspnea with exertion. A computed tomography (CT) scan detected interstitial pneumonia, swelling of bilateral submandibular glands, bilateral hilar and mediastinal lymphadenopathy, and several nodules in bilateral kidneys. His serum levels of IgG and IgG4 were elevated. The biopsy specimen of auricular cartilage showed infiltrations of inflammatory cells and fibrosis consistent with RP. The IgG4-positive cells were not observed in auricular cartilage. The patient met the diagnostic criteria of RP, including bilateral auricular chondritis, conjunctivitis, iritis and polyarthritis. The biopsy specimens of lung and kidney revealed the significant infiltrations of IgG4-positive plasma cells and fibrosis. We also diagnosed him as having IgG4-RD, affecting bilateral submandibular glands, hilar and mediastinal lymph nodes, lungs, and kidneys. Thus, RP preceded the onset of IgG4-RD. Corticosteroid therapy improved the symptoms and CT scan findings. In conclusion, RP and IgG4-RD do coexist; however, the pathogenesis of their coexistence is unknown. PMID:27396510

The surgical specimen contained a mass exhibiting the histological features of immunoglobulin (Ig)G4-related disease, including lymphoplasmacytic infiltration and sclerosis with numerous IgG4-producing plasma cells. Postoperatively, an elevation of the serum IgG4 level was confirmed at 403 mg/dL; however, there was no evidence of tubulointerstitial nephritis or glomerulopathy, including membranous nephropathy, and the urothelium of the renal pelvis was intact without inflammation. We herein report this case in which IgG4-related disease of the renal pelvic region presented with a mass lesion in the intrarenal sinus near the renal pelvis, not 'pyelitis' (as described by Stone).

    IgG4-related systemic disease, including autoimmune pancreatitis, is a multi-organ disorder characterized by elevated serum immunoglobulin G4 (IgG4) concentration and IgG4-positive plasma cell infiltration. We report the case of a 67-year-old man with IgG4-related tubulointerstitial nephritis, presenting with markedly enlarged kidneys and renal dysfunction. The serum IgG4 level was elevated with 4200 mg/dl and pathological examination revealed patchy, clearly fringed areas of IgG4-positive plasma cell infiltration and advanced fibrosis in the renal parenchyma, perirenal tissue and lymph nodes. With oral prednisolone at a dose of 60 mg daily, a contraction of the kidneys and an improvement of renal function were observed. No recurrence of the disease was observed during the reduction of prednisolone to 2 mg daily over 4 years.

    A 62-year-old woman was admitted for nephrotic syndrome and lung tumor. A renal biopsy showed membranous features of the glomeruli. Immunofluorescence studies revealed granular IgG4-κ deposits along with the glomerular basement membrane. Electron microscopy revealed granular electron-dense deposits. Further study denied multiple myeloma. Light microscopy of the resected lung tumor revealed IgG4-related lung disease with no malignancy. Steroid therapy induced a remission of the nephrotic syndrome, with no recurrence of the lung tumor. We consider that this is the first case of a proliferative glomerulonephritis with monoclonal IgG deposits of IgG4 subclass, and a rare concurrence with IgG4-related disease. PMID:25878779

    IgG4-related disease is a novel lymphoproliferative disorder that shows hyper-IgG4-γ-globulinemia and IgG4-producing plasma cell expansion in affected organs with fibrotic or sclerotic changes. Patients show systemic inflammatory conditions and various symptoms depending on the affected organ. Since the first report of patients with elevated serum IgG4 in sclerosing pancreatitis in 2001, various systemic disorders described by many names have been reported. Despite similarities in the organs involved in IgG4-related Mikulicz's disease and Sjögren's syndrome, there are marked clinical and pathological differences between these conditions. Most patients diagnosed with autoimmune pancreatitis in Japan have IgG4-related pancreatitis [Type 1 autoimmune pancreatitis (AIP), lymphoplasmacytic sclerosing pancreatitis (LPSP)], a disease distinct from some of the western type [Type 2 AIP, idiopathic duct-centric chronic pancreatitis (IDCP), autoimmune pancreatitis with granulocytic epithelial lesions (GEL)]. Diagnosis of IgG4-related disease is characterized by both elevated serum IgG4 (>135 mg/dL) and histopathological features including lymphocyte and IgG4(+) plasma cell infiltration (IgG4(+) plasma cells/IgG(+) plasma cells>40%). Differential diagnosis from other distinct disorders, such as sarcoidosis, Castleman's disease, Wegener's granulomatosis, lymphoma, cancer, and other existing conditions associated with high serum IgG4 level or abundant IgG4-bearing plasma cells in tissues is necessary. We have begun a clinical prospective study to establish a treatment strategy (Phase II prospective treatment study for IgG4-multiorgan lymphoproliferative syndrome: UMIN R000002311). PMID:21628856

    The IgG4-related disease is a fibroinflammatory disease characterized by tumefactive lesions, a dense lymphoplasmacytic infiltrate rich in IgG4-positive plasma cells, storiform fibrosis, and, often but not always, elevated serum levels of IgG4. Idiopathic CD4 lymphocytopenia is a heterogenic and rare syndrome characterized by the detection of a persistent absolute CD4 T cells count <300 cells/mm(3) (or <20% of total T cells) in more than one occasion and no evidence of HIV infection in absence of immunodeficiency or therapy associated with depressed levels of CD4 T cells. We report the case of a 50-year-old man with a multiorgan IgG4-related disease presenting in a temporal association with a profound and symptomatic idiopathic CD4 lymphocytopenia. Both clinical pictures improved after steroid treatment. Idiopathic CD4 lymphocytopenia has been associated with a number of autoimmune conditions but, to the best of our knowledge, this is the first case in which an association with the IgG4-related disease is reported.

    A 69-year-old man had undergone left ureteronephrectomy because of a left renal pelvic tumor, however the pathological diagnosis was inflammatory pseudotumor. About 1 year later, computed tomography showed a mass at the right kidney near the hilar. Ureterorenoscopy and urine cytology were performed, and their results showed no evidence of malignancy. He had been followed closely without therapy. The mass increased in size during follow-up, and we reviewed the surgical specimen of the left ureteronephrectomy. Immunohistochemical studies revealed diffuse infiltration by IgG4 positive plasma cell. His serum IgG4 was high. We diagnosed him as IgG4-related kidney disease. In response to treatment with corticosteroid, the size of the tumor and serum IgG4 levels decreased. Most reported cases of IgG4-related disease involving kidney have a history of prior pancreatic involvement. We report a rare long term follow-up case of IgG4-related kidney disease without pancreatic involvement. PMID:24908817

    IgG4-related disease has been recently defined as a distinct clinic-pathologic entity, characterized by dense IgG-4 plasmacytic infiltration of diverse organs, fibrosis, and tumefactive lesions. Salivary and lacrimal glands are a target of this disease and, when affected, may clinically resemble Küttner tumor, Mikulicz disease, or orbital inflammatory pseudotumor. In some patients, the disease is systemic, with metachronous involvement of multiple organs, including the pancreas, aorta, kidneys, and biliary tract. We report a 66-year old man who presented with salivary gland enlargement and severe salivary hypofunction and was diagnosed with IgG4-related disease on the basis of a labial salivary gland biopsy. Additional features of his illness included a marked peripheral eosinophilia, obstructive pulmonary disease, and lymphoplasmacytic aortitis. He was evaluated in the context of a research registry for Sjögren syndrome and was the only one of 2594 registrants with minor salivary gland histopathologic findings supportive of this diagnosis.

    IgG4-related systemic disease is now recognized as a systemic disease that may affect various organs. The diagnosis is usually made in patients who present with elevated IgG4 in serum and tissue infiltration of diseased organs by numerous IgG4+ plasma cells, in the absence of validated diagnosis criteria. We report the clinical, laboratory, and histologic characteristics of 25 patients from a French nationwide cohort. We also report the treatment outcome and show that despite the efficacy of corticosteroids, a second-line treatment is frequently necessary. The clinical findings in our patients are not different from the results of previous reports from Eastern countries. Our laboratory and histologic findings, however, suggest, at least in some patients, a more broad polyclonal B cell activation than the skewed IgG4 switch previously reported. These observations strongly suggest the implication of a T-cell dependent B-cell polyclonal activation in IgG4-related systemic disease, probably at least in part under the control of T helper follicular cells.

    We herein report a case of IgG4-related lung disease (IgG4-RLD) associated with autoimmune hemolytic anemia (AIHA). A 73-year-old Japanese female visited our hospital for an examination following an abnormal chest X-ray in 1999. She was diagnosed with bronchiolitis and AIHA, and treatment with prednisolone was started. After seven years, she visited our department due to a cough. Chest computed tomography (CT) demonstrated focal consolidation with ground-glass attenuations and thickened bronchial walls in the bilateral lungs. She was clinically diagnosed and treated for bronchial asthma. CT findings had shown no changes, and a lung biopsy was performed using video-assisted thoracic surgery at eleven years from the first diagnosis of AIHA. The pathological findings demonstrated the presence of peribronchovascular lymphoplasmacytic infiltrates with stromal fibrotic changes, admixed with many IgG4-positive plasma cells. Furthermore, the patient's serum IgG4 level was high, and her CT findings did not show any obvious abnormal findings in the any organs other than the lungs. She was diagnosed with IgG4-RLD based on the findings. We believe that this case report of IgG4-RLD associated with AIHA is clinically helpful for a better understanding of these diseases, although there are five reported cases of IgG4-related disease associated with AIHA.

    Immunoglobulin G4 (IgG4)-related lung diseases can occur in patients with autoimmune pancreatitis (AIP). However, the causal relationship between AIP and acquired hemophilia A (AH) is unknown. We herein report the first case of AH associated with IgG4-related lung disease that developed in a patient with AIP. A 65-year-old asymptomatic man with a history of AIP and sclerosing cholangitis diagnosed at the age of 57 was admitted to our hospital due to an abnormal reticulonodular shadow on chest X-ray. An examination of lung biopsy specimens revealed IgG4-positive plasma cell infiltration in the interstitium. The serum IgG4 level was elevated. One year later, the patient developed a progressive severe hematoma in the left femoral muscle. On admission, laboratory examinations revealed severe anemia with a markedly prolonged activated partial prothrombin time, a decreased level of factor VIII (FVIII) activity, and the existence of anti-FVIII antibodies. These findings were consistent with a diagnosis of AH. No relapse has been observed over the past 25 months, during which time, corticosteroid therapy has been continuously administered.

    A 61-year-old male from Northeast China presented with a 2-mo history of abdominal distension, pruritus and jaundice. Laboratory testing revealed an elevated serum IgG4 level. A computed tomography scan showed a typical feature of autoimmune pancreatitis (AIP) and cholecystocholangitis. Early gastric cancer was incidentally discovered when endoscopic untrasound-guided fine needle aspiration (EUS-FNA) of the pancreas was carried out. The patient underwent radical subtotal gastrectomy for gastric cancer combined with cholecystectomy. Helicobacter pylori (H. pylori) and IgG4-positive plasmacytes were detected in gastric cancer tissue, pancreatic EUS-FNA sample and resected gallbladder specimen by immunohistochemistry. The patient was diagnosed with H. pylori-positive IgG4-related AIP and sclerosing cholecystocholangitis as well as H. pylori-positive gastric cancer. He responded well to steroid therapy and remains healthy with no signs of recurrence at one year follow-up. We speculate that H. pylori might act as a trigger via direct or indirect action in the initiation of onset of gastric cancer and multiorgan IgG4-related disease. PMID:25805956

    The IgG4-related systemic disease is a recently described entity of fibro-inflammatory systemic damage. Although initially described in some forms of pancreatitis, the disease can affect all organs. The common histological features include a lymphoplasmacytic infiltration (especially to IgG4), fibrosis and phlebitis. Elevated serum level of IgG4 is also often present. This rare but certainly underdiagnosed disease must be kept in mind of all clinician faced to a non-specific inflammatory lesion. We report a case of ocular inflammation and lung tumors in a patient of 84 years for which the diagnosis was made through immunolabelling with IgG4 in lesions biopsied. PMID:23159548

    Immunoglobulin G4-related disease (IgG4-RD) represents an immune-mediated fibroinflammatory condition with a characteristic histopathological appearance that can affect various organs. Although numerous single-organ manifestations have been described more than a century ago, its systemic nature and unique features were only discovered in the last 2 decades, when IgG4-RD emerged as a new entity of disease. IgG4-RD is usually considered a rare disease, but its true epidemiology has not yet been fully clarified. Also, despite recent advances in the identification of the underlying immunological processes, its pathophysiology is only incompletely understood till now. The diagnostic workup of IgG4-RD is complex and usually requires a combination of clinical examination, imaging, histological, and serological analyses. However, no finding alone is specific for IgG4-RD. Therefore, its diagnosis requires careful interpretation of examination results in context with the patient's clinical appearance as well as the exclusion of a broad variety of differential diagnoses. The past years brought rapid advances concerning this novel disease entity: diagnostic criteria, further insights into the underlying immunological processes, new biomarkers, and novel therapeutic approaches were proposed and widened the knowledge in the field of IgG4-RD. Still, a greater number of questions remain unanswered, and many recent developments require further discussion and proof from clinical trials. This review should give an overview on current knowledge and future perspectives in epidemiology, pathophysiology, diagnosis, and therapy of IgG4-RD. PMID:26929632

    Immunoglobulin G4-related disease (IgG4-RD) is an emerging clinicopathologic entity characterized by both IgG4+ plasma cell infiltration and fibrosis in one or more organs, prototypically pancreas or salivary/lacrimal glands. IgG4-RD in the thyroid (IgG4-RTD) is an area of active study, and the relationship between IgG4-RTD and Hashimoto thyroiditis is not fully delineated due to their overlapping histologic features. Retrospective review was performed of all thyroidectomy cases demonstrating lymphocytic inflammation at a single institution over a 4-year period. Approximately half (23/38) of patients had a clinical diagnosis of Hashimoto thyroiditis (HT). Nine of the 38 patients had increased absolute and relative numbers of IgG4+ plasma cells. Patients with a clinical diagnosis of HT had increased lymphoplasmacytic inflammation, but the relative proportion of IgG4+ plasma cells was not increased compared to patients without HT. There was no correlation between IgG4 levels and the amount of fibrosis in patients with or without HT. Patients identified as having the fibrosing variant of HT were not more likely to have increased levels of IgG4+ plasma cells than those without. There is significant morphologic and immunohistochemical overlap between HT and IgG4-RTD. Future studies to identify specific characteristics of IgG4-RTD involving the thyroid are necessary to accurately define this entity.

    Riedel's thyroiditis (RT) is a rare chronic fibrosing disorder characterized by a hard, infiltrative lesion in the thyroid gland, which is often associated with multifocal fibrosclerosis. Immunoglobulin G4-related disease (IgG4-RD) is typified by infiltration of IgG4-positive plasma cells into multiple organs, resulting in tissue fibrosis and organ dysfunction. In order to evaluate the clinicopathological features of RT and its relationship with IgG4-RD, we performed a Japanese literature search using the keywords "Riedel" and "Riedel's thyroiditis." We used the electronic databases Medline and Igaku Chuo Zasshi, the latter of which is the largest medical literature database in Japan. The diagnosis of RT was based on the presence of a fibroinflammatory process with extension into surrounding tissues. Only 10 patients in Japan fulfilled RT diagnostic criteria during the 25-year period between 1988 and 2012. Two patients with confirmed IgG4/IgG immunohistochemical findings demonstrated 43 and 13 IgG4-positive plasma cells per high-power field, respectively, and the IgG4-positive/IgG-positive plasma cell ratios of 20% and less than 5%. Of the 10 patients with RT, two received glucocorticoids, one of whom experienced marked shrinkage of the thyroid lesion. One patient had extra-thyroid involvement in the form of retroperitoneal fibrosis. Although the clinicopathological features of RT suggest that IgG4-RD may be the underlying condition in some cases, further investigation is needed to clarify the etiology of RT in relation to IgG4-RD.

    Immunoglobulin G4-related systemic disease (IgG4-RSD) is a recently defined emerging entity characterized by a diffuse or mass forming inflammatory reaction rich in IgG4-positive plasma cells associated with fibrosclerosis and obliterative phlebitis. IgG4-RSD usually affects middle aged and elderly patients, with a male predominance. It is associated with an elevated serum titer of IgG4, which acts as a marker for this recently characterized entity. The prototype is IgG4-related sclerosing pancreatitis or autoimmune pancreatitis (AIP). Other common sites of involvement are the hepatobiliary tract, salivary gland, orbit, and lymph node, however practically any organ can be involved, including upper aerodigestive tract, lung, aorta, mediastinum, retroperitoneum, soft tissue, skin, central nervous system, breast, kidney, and prostate. Fever or constitutional symptoms usually do not comprise part of the clinical picture. Laboratory findings detected include raised serum globulin, IgG and IgG4. An association with autoantibody detection (such as antinuclear antibodies and rheumatoid factor) is seen in some cases. Steroid therapy comprises the mainstay of treatment. Disease progression with involvement of multiple organ-sites may be encountered in a subset of cases and may follow a relapsing-remitting course. The principal histopathologic findings in several extranodal sites include lymphoplasmacytic infiltration, lymphoid follicle formation, sclerosis and obliterative phlebitis, along with atrophy and destruction of tissues. Immunohistochemical staining shows increased IgG4+ cells in the involved tissues (>50 per high-power field, with IgG4/IgG ratio >40%). IgG4-RSD may potentially be rarely associated with the development of lymphoma and carcinoma. However, the nature and pathogenesis of IgG4-RSD are yet to be fully elucidated and provide immense scope for further studies. PMID:22187229

    Recent studies have proposed nomenclatures of type 1 autoimmune pancreatitis (AIP) (IgG4-related pancreatitis), IgG4-related sclerosing cholangitis (IgG4-SC), IgG4-related cholecystitis, and IgG4-related hepatopathy as IgG4-related disease (IgG4-RD) in the hepato-bilio-pancreatic system. In IgG4-related hepatopathy, a novel concept of IgG4-related autoimmune hepatitis (AIH) with the same histopathological features as AIH has been proposed. Among organs involved in IgG4-RD, associations with pancreatic and biliary lesions are most frequently observed, supporting the novel concept of “biliary diseases with pancreatic counterparts.” Targets of type 1 AIP and IgG4-SC may be periductal glands around the bile and pancreatic ducts. Based on genetic backgrounds, innate and acquired immunity, Th2-dominant immune status, regulatory T (Treg) or B cells, and complement activation via a classical pathway may be involved in the development of IgG4-RD. Although the role of IgG4 remains unclear in IgG4-RD, IgG4-production is upregulated by interleukin 10 from Treg cells and by B cell activating factor from monocytes/basophils with stimulation of toll-like receptors/nucleotide-binding oligomerization domain-like receptors. Based on these findings, we have proposed a hypothesis for the development of IgG4-RD in the hepato-bilio-pancreatic system. Further studies are necessary to clarify the pathogenic mechanism of IgG4-RD. PMID:25228969

    An elevated serum IgG4 level is one of the most useful factors in the diagnosis of IgG4-related disease (IgG4-RD). In this study, we performed a meta-analysis of the published articles assessing the diagnostic accuracy of serum IgG4 concentrations for IgG4-RD. The databases of MEDLINE/PubMed, EMBASE and Web of Science were systematically searched for relevant studies. Sensitivities and specificities of serum IgG4 in each study were calculated, and the hierarchical summary receiver operating characteristic (HSROC) model with a random effects model were employed to obtain the individual and pooled estimates of sensitivities and specificities. In total, twenty-three studies comprising 6048 patients with IgG4-RD were included in the meta-analysis. The pooled sensitivity was 85% with a 95% confidence interval (CI) of 78–90%; the pooled specificity was 93% with a 95% CI of 90–95%. The HSROC curve for quantitative serum IgG4 lies closer to the upper left corner of the plot, and the area under the curve (AUC) was 0.95 (95% CI 0.93, 0.97), which suggested a high diagnostic accuracy of serum IgG4 for the entity of IgG4-RD. Our study suggests that serum IgG4 has high sensitivity and specificity in the diagnosis of IgG4-RD. PMID:27558881

    An elevated serum IgG4 level is one of the most useful factors in the diagnosis of IgG4-related disease (IgG4-RD). In this study, we performed a meta-analysis of the published articles assessing the diagnostic accuracy of serum IgG4 concentrations for IgG4-RD. The databases of MEDLINE/PubMed, EMBASE and Web of Science were systematically searched for relevant studies. Sensitivities and specificities of serum IgG4 in each study were calculated, and the hierarchical summary receiver operating characteristic (HSROC) model with a random effects model were employed to obtain the individual and pooled estimates of sensitivities and specificities. In total, twenty-three studies comprising 6048 patients with IgG4-RD were included in the meta-analysis. The pooled sensitivity was 85% with a 95% confidence interval (CI) of 78-90%; the pooled specificity was 93% with a 95% CI of 90-95%. The HSROC curve for quantitative serum IgG4 lies closer to the upper left corner of the plot, and the area under the curve (AUC) was 0.95 (95% CI 0.93, 0.97), which suggested a high diagnostic accuracy of serum IgG4 for the entity of IgG4-RD.

  11. Successful treatment of pediatric IgG4 related systemic disease with mycophenolate mofetil: case report and a review of the pediatric autoimmune pancreatitis literature

    PubMed Central

    2011-01-01

    Autoimmune pancreatitis is frequently associated with elevated serum and tissue IgG4 levels in the adult population, but there are few reports of pediatric autoimmune pancreatitis, and even fewer reports of IgG4 related systemic disease in a pediatric population. The standard of care treatment in adults is systemic corticosteroids with resolution of symptoms in most cases; however, multiple courses of corticosteroids are occasionally required and some patients require long term corticosteroids. In these instances, steroid sparing disease modify treatments are in demand. We describe a 13-year-old girl with IgG4 related systemic disease who presented with chronic recurrent autoimmune pancreatitis resulting in surgical intervention for obstructive hyperbilirubinemia and chronic corticosteroid treatment. In addition, she developed fibrosing medianstinitis as part of her IgG4 related systemic disease. She was eventually successfully treated with mycophenolate mofetil allowing for discontinuation of corticosteroids. This is the first reported use of mycophenolate mofetil for IgG4 related pancreatitis. Although autoimmune pancreatitis as part of IgG4 related systemic disease is rarely reported in pediatrics, autoimmune pancreatitis is also characterized as idiopathic fibrosing pancreatitis. All pediatric autoimmune pancreatitis cases reported in the world medical literature were identified via a PUBMED search and are reviewed herein. Twelve reports of pediatric autoimmune pancreatitis were identified, most of which were treated with corticosteroids or surgical approaches. Most case reports failed to report IgG4 levels, so it remains unclear how commonly IgG4 related autoimmune pancreatitis occurs during childhood. Increased evaluation of IgG4 levels in patients with autoimmune pancreatitis may shed further light on the association of IgG4 with pancreatitis and the underlying pathophysiology. PMID:21205323

    Idiopathic granulomatous mastitis (IGM) is a benign, frequently severe chronic inflammatory lesion of the breast. Its etiology remains unknown and reported cases vary in their presentation and histologic findings with an optimal treatment algorithm yet to be described owing mainly to the disease's heterogeneity. IgG4-related disease (IgG4-RD) is a newly recognized systemic fibroinflammatory condition characterized by a dense lymphoplasmacytic infiltrate with many IgG4-positive plasma cells, storiform fibrosis, and obliterative phlebitis. Immunosuppressive therapy is considered to be an effective first-line therapy for IgG4-RD. We sought to clarify and classify chronic mastitis according to the histologic findings of IgG4-RD mastitis with respect to IGM and to develop a robust diagnostic framework to help select patients for optimal treatment strategies. Using the largest collection to date (43 cases from Egypt and Morocco), we show that despite sharing many features, IGM and IgG4-RD mastitis are separate diseases. To diagnostically separate the diseases, we created a classification schema-termed the Michigan Classification-based upon our large series of cases, the consensus statement on IgG4-RD, and the histologic description of IGM in the literature. Using our classification, we discerned 17 cases of IgG4-RD and 8 cases of IGM among the 43 chronic mastitis cases, with 18 indeterminate cases. Thus, our Michigan Classification can form the basis of rational stratification of chronic mastitis patients between these two clinically and histopathologically heterogeneous diseases.

    Autoimmune pancreatitis (AIP) is a form of chronic pancreatitis that is categorized as type 1 or type 2 according to the clinical profile. Type 1 AIP, which predominantly presents in a few Asian countries, is a hyper-IgG4-related disease. We report a case of IgG4-related AIP overlapping with Mikulicz’s disease and lymphadenitis, which is rare and seldom reported in literature. A 63-year male from Northeast China was admitted for abdominal distension lasting for one year. He presented symmetric swelling of the parotid and submandibular glands with slight dysfunction of salivary secretion for 6 mo. He had a 2-year history of bilateral submandibular lymphadenopathy without pain. He underwent surgical excision of the right submandibular lymph node one year prior to admission. He denied any history of alcohol, tobacco, or illicit drug use. Serological examination revealed high fasting blood sugar level (8.8 mmol/L) and high level of IgG4 (15.2 g/L). Anti-SSA or anti-SSB were negative. Computed tomography of the abdomen showed a diffusely enlarged pancreas with loss of lobulation. Immunohistochemical stain for IgG4 demonstrated diffuse infiltration of IgG4-positive plasma cells in labial salivary gland and lymph node biopsy specimens. The patient received a dose of 30 mg/d of prednisone for three weeks. At this three-week follow-up, the patient reported no discomfort and his swollen salivary glands, neck lymph node and pancreas had returned to normal size. The patient received a maintenance dose of 10 mg/d of prednisone for 6 mo, after which his illness had not recurred. PMID:24409081

    IgG4-related disease (IgG4-RD) is a systemic inflammatory disease characterized by marked infiltration of IgG4-positive (+) plasma cells into affected organs, but the concept of this disease has only recently been established. Coronary vasculitis is a rare disease that can cause sudden death, and it has recently been reported that IgG4-RD may be associated with vasculitis, including periarteritis and coronary disease. In this paper we report an autopsy case of sudden death of a man in his thirties, in which coronary periarteritis with features of IgG4-related periarteritis was detected. IgG4-RD was suspected from the presence of the following histopathological features: (1) markedly thickened adventitia and marked infiltration of the adventitia and periarterial fat by lymphocytes and plasma cells; and (2) infiltration of IgG4-positive plasma cells (ratio of IgG4+ cells to IgG4+ cells of >40 %, 50 IgG4+ plasma cells per high-power field) on immunostaining. The etiology and pathophysiology of IgG4-RD and IgG4-related periarteritis are still unclear, and further investigation of these conditions and their association with coronary lesions is needed. Careful consideration should be given to the possible presence of IgG4-RD when forensic pathologists encounter cases of sudden death accompanied by coronary periarteritis.

    Abstract The aim of this study is to study the clinical features and diagnostic performance of IgG4 in Chinese populations with IgG4-related diseases (IgG4-RDs). The medical records of 2901 adult subjects who underwent serum IgG4 level tests conducted between December 2007 and May 2014 were reviewed. Serum concentrations of IgG4 were measured in 2901 cases, including 161 (5.6%) patients with IgG4-RD and 2740 (94.4%) patients without IgG4-RD (non-IgG4-RD group). The mean age of the IgG4-RD patients was 58.4 ± 16.1 years (range: 21–87), and 48 (29.8%) were women. The mean serum IgG4 level was significantly much higher in IgG4-RD patients than in non-IgG4-RD (1062.6 vs 104.3 mg/dL, P < 0.001) participants. For IgG4 >135 mg/dL, the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), likelihood ratio (LR)+, and LR− were 86%, 77%, 18%, 99%, 3.70, and 0.19, respectively. When the upper limit of normal was doubled for an IgG4 >270 mg/dL, the corresponding data were 75%, 94%, 43%, 98%, 12.79, and 0.26, respectively. For IgG4 >405 mg/dL (tripling the upper limit of normal), the corresponding data were 62%, 98%, 68%, 98%, 37.00, and 0.39, respectively. When calculated according to the manufacturer's package insert cutoff (>201 mg/dL) for the diagnosis of IgG4-RD, the corresponding sensitivity, specificity, PPV, NPV, LR+, and LR− were 80%, 89%, 29%, 99%, 7.00, and 0.23, respectively. For IgG4 >402 mg/dL (>2× the upper limit of the normal range), the corresponding data were 62%, 98%, 68%, 98%, 36.21, and 0.39, respectively. For IgG4 >603 mg/dL (>3× the upper limit of the normal range), the corresponding data were 50%, 99%, 84%, 97%, 90.77 and 0.51, respectively. The optimal cutoff value of serum IgG4 (measured by nephelometry using a Siemens BN ProSpec instrument and Siemens reagent) for the diagnosis of IgG4-RD was 248 mg/dL, the sensitivity and specificity were 77.6% and 92.8%, respectively.

    Patient: Male, 62 Final Diagnosis: Auto-immune pancreatitis Symptoms: Jaundice • lymfadenopathy Medication: — Clinical Procedure: Laboratory • imaging Specialty: Gastroenterology and Hepatology Objective: Unusual clinical course Background: Autoimmune pancreatitis (AIP) is an important clinical pathologic concept of IgG-4-related disease. AIP is a rare cause of chronic pancreatitis, characterized by a fibroinflammatory process by lymphoplasmacytic infiltrates, storiform fibrosis, obliterative phlebitis, and increased IgG4+ plasma cells, leading to dysfunction of the pancreas. Affected patients with AIP frequently have disease affecting other organs or sites with similar histologic changes, elevated IgG4+ plasma cell infiltrate, and good response to corticosteroid therapy. These diseases often are not limited to the pancreas and the pancreas may not be involved at all. Case Report: We report a 62-year-old man with obstructive jaundice with pre-existent submandibular lymphadenopathy. Diagnosis of AIP was based on diagnostic criteria by the HISORT-criteria in combination with elevated IgG-4 serum levels. CT revealed a focal enlargement of the head of the pancreas, as well as mesenteric peripancreatic and mediastinal lymphadenopathy. He was treated with high-dose steroid in combination with azathioprine and showed good clinical response. Conclusions: We report a case with pre-existent submandibular lymphadenopathy and obstructive jaundice based on AIP type 1, both in the context of IgG4-related disease. PMID:26537530

    Immunoglobulin G4-related disease (IgG4-RD) is a recently described inflammatory disease involving multiple organs. Prostate involvement with IgG4-RD is very rare. In this report, we describe a case of IgG4-related prostatitis progressed from localized IgG4-related lymphadenopathy. This patient was present with urine retention symptoms. MRI and CT examination revealed the prostatic enlargement and the multiple lymphadenopathy. Serum IgG4 levels were elevated. Prostatic tissue samples resected both this time and less than 1 year earlier showed the same histological type of prostatitis with histopathologic and immunohistochemical findings characteristic of IgG4-RD. The right submandibular lymph nodes excised 2 years earlier were eventually proven to be follicular hyperplasia-type IgG4-related lymphadenopathy. This is the first case of IgG4-RD that began as localized IgG4-related lymphadenopathy and progressed into a systemic disease involving prostate and multiple lymph nodes. This patient showed a good response to steroid therapy. This leads us to advocate a novel pathogenesis of prostatitis, and a novel therapeutic approach against prostatitis. Pathologists and urologists should consider this disease entity in the patients with elevated serum IgG4 levels and the symptoms of prostatic hyperplasia to avoid ineffective medical or unnecessary surgical treatment.

    Abstract IgG4-related disease (IgG4-RD) is a novel systemic disease entity characterized by elevated serum IgG4 and tissue infiltration of IgG4-positive plasma cells accompanied by severe fibrosis. Although recent studies demonstrated that innate immune cells including monocytes and macrophages might promote local fibrosis and IgG4 production, the pathological mechanism remains unclear. In this study, we sought to identify the disease-associated genes, especially innate immune molecules. Gene expression was analyzed by DNA microarray in submandibular glands (SMGs) from patients with IgG4-RD (n = 5), chronic sialoadenitis (CS) (n = 3), and controls (n = 3). Differentially expressed genes (DEGs) were validated by real-time polymerase chain reaction (PCR) and immunohistochemical staining in IgG4-RD (n = 18), CS (n = 4), Sjögren syndrome (n = 11), and controls (n = 10). Gene expression patterns in the 3 groups were quite different from each other by the pvclust method and principal components analysis. In IgG4-RD, 1028 upregulated genes and 692 downregulated genes were identified as DEGs (P < 0.05). Gene Ontology (GO) term analysis indicated that the upregulated DEGs in IgG4-RD encoded proteins involved in T/B cell activation and chemotaxis. PCR validated significantly higher expression of macrophage receptor with collagenous structure (MARCO), a pattern-recognition receptor, in IgG4-RD compared with the other groups (P < 0.01). Immunohistochemical analysis confirmed that the expression pattern of MARCO was similar to that of the M2 macrophage marker CD163. MARCO was identified as a disease-associated molecule in IgG4-RD by DNA microarray. Moreover, M2 macrophages might contribute to the initiation of IgG4-RD via MARCO. PMID:26886650

    Many studies about serum IgG4 for the diagnosis of IgG4-related disease (IgG4-RD) have been reported. However, these studies had relatively small sample sizes and the diagnostic accuracy values varied much between them.The aim of this study was to perform a meta-analysis to evaluate the diagnostic value of serum IgG4 for IgG4-RD.We conducted a search of relevant articles using MEDLINE, EMBASE, Web of Science, SCOPUS, and Cochrane Library databases published before December 2015.Studies those assessed the diagnostic accuracy of serum IgG4 for IgG4-RD and those provided the cut-off value for serum IgG4 were included.Data were synthesized using the random-effect model. Statistical analysis was performed using STATA with the MIDAS module and Meta-DiSc 1.4 software.A total of 9 case-control studies were analyzed, which included 1235 patients with IgG4-RD and 5696 overall controls. The pooled estimate, for a cut-off value ranged from 135 to 144 mg/dL, produced a sensitivity of 87.2% (95% CI, 85.2-89.0%) and a specificity of 82.6% (95% CI, 81.6-83.6%). The positive likelihood ratio (PLR), negative likelihood ratio (NLR), and diagnostic odds ratio (DOR) were 6.48 (95% CI, 3.98-10.57), 0.14 (95% CI, 0.09-0.21), and 45.15 (95% CI, 23.41-87.06), respectively. The area under the curve (AUC) of the summary receiver operating characteristic curve (SROC) was 0.94 (0.92-0.96). When a cut-off value of 2-fold the upper limit of normal was used (ranged from 270 to 280 mg/dL), the pooled sensitivity was 63% (95% CI, 60.0-66.0%), and the specificity was 94.8% (95% CI, 94.1-95.4%). The PLR, NLR, and DOR were 13.3 (95% CI, 7.39-24.0), 0.41 (95% CI, 0.29-0.58) and 33.42 (95% CI, 13.88-80.43), respectively. The AUC of the SROC was 0.92 (0.90-0.94).Only a relatively small number of studies were included, and significant heterogeneity was observed in this meta-analysis.Serum IgG4 is a modestly effective marker to diagnose IgG4-RD. Doubling the cut-off value for IgG4 could not improve the

    Patient:Female, 55 Final Diagnosis: Autoimmune pancreatitis Symptoms: Abdominal pain • weight loss Medication: Prednisone Clinical Procedure: Admitted to the hospital Specialty: Gastroenterology and Hepatology Objective: Challenging differential diagnosis Background: Autoimmune pancreatitis is an IgG4-related fibroinflammatory condition often associated with obstructive jaundice, as most lesions are located at the head of the pancreas. IgG4 level can help in the diagnosis, but it is normal in nearly 30% of affected patients. Case Report: A 55-year-old woman presented with a 5-month history of 20-pound unintentional weight loss and intermittent abdominal pain. She had an unremarkable abdominal exam and significant findings included a small, non-mobile rubbery left axillary lymph node. Complete blood count, complete metabolic panel, amylase, anti-smooth muscle antibody, antimitochondrial antibody, carcinoembryonic antigen, Ca 19-9, complement C3 and C4, antinuclear antibody, anti-Smith double-strand antibody, and IgG4 were all within normal limits. CT of the abdomen showed a mass in the junction of the body and tail of the pancreas and endoscopic ultrasound showed it as encasing the splenic artery. Fine-needle aspiration cytology demonstrated follicular hyperplasia, obliterative phlebitis, storiform fibrosis, and negative staining for IgG4 and malignancy. Left axillary lymph node biopsy demonstrated follicular hyperplasia. PET scan revealed hypermetabolic uptake of the pancreas tail, bone marrow, and spleen, as well as diffuse lymphadenopathy. Bone marrow biopsy showed follicular hyperplasia and was negative for malignancy. The patient was started on 40 mg of oral prednisone for possible autoimmune disease. During follow-up, she reported progressive improvement and a repeat PET scan 6 months later showed marked improvement. Conclusions: A normal IgG4 value should not decrease the clinical suspicion of IgG4-related disease. If clinical, histological, and

    Background IgG4-related disease (IgG4-RD) is a systemic fibroinflammatory condition, characterised by an elevated serum IgG4 concentration and abundant IgG4-positive plasma cells in the involved organs. An important question is whether the elevated IgG4 response is causal or a reflection of immune-regulatory mechanisms of the disease. Objectives To investigate if the IgG4 response in IgG4-RD represents a generalised polyclonal amplification by examining the response to common environmental antigens. Methods Serum from 24 patients with IgG4-RD (14 treatment-naive, 10 treatment-experienced), 9 patients with primary sclerosing cholangitis and an elevated serum IgG4 (PSC-high IgG4), and 18 healthy controls were tested against egg white and yolk, milk, banana, cat, peanut, rice and wheat antigens by radioimmunoassay. Results We demonstrated an elevated polyclonal IgG4 response to multiple antigens in patients with IgG4-RD and in PSC-high IgG4, compared with healthy controls. There was a strong correlation between serum IgG4 and antigen-specific responses. Responses to antigens were higher in treatment-naive compared with treatment-experienced patients with IgG4-RD. Serum electrophoresis and immunofixation demonstrated polyclonality. Conclusions This is the first study to show enhanced levels of polyclonal IgG4 to multiple antigens in IgG4-RD. This supports that elevated IgG4 levels reflect an aberrant immunological regulation of the overall IgG4 response, but does not exclude that causality of disease could be antigen-driven.

    Immunoglobulin (IgG) 4-related disease is characterized by elevated serum IgG4 and tissue infiltration by IgG4-positive plasma cells. We report a case of IgG4-related inflammation of the orbit simulating extranodal marginal zone B-cell lymphoma (EMZL). A 72-year-old female complained of bilateral eyelid swelling for three years. A MRI scan demonstrated two kinds of lesions, tumor 1, presenting with a predominantly low density, and tumor 2, of relatively high density. Laboratory tests showed high serum IgG4 concentrations, measuring 991 mg/dl. Partial resection of each tumor was conducted in September 2011. Based on the clinicopathological findings, tumors 1 and 2 were diagnosed as IgG4-related inflammation and EMZL, respectively. The patient initially received oral prednisolone at 30 mg/per day, followed by irradiation with a total dosage of 30 Gy to both eyes. The bilateral tumors consequently diminished, and she is currently well with no recurrence or systemic involvement. In conclusion, EMZL can arise from massive IgG4-related orbital inflammation. Since IgG4-related inflammation can represent multiple nodular lesions, biopsies from multiple sites within the lesion are required to make a correct diagnosis in selected cases. Oral prednisolone combined with radiotherapy is an effective treatment for patients with IgG4-related ophthalmic disease simulating EMZL.

    IgG4-related disease is a recently recognized clinical entity. It is characterized by diffuse organ swelling or mass formation, a dense lymphoplasmacytic infiltrate rich in IgG4-positive plasma cells with fibrosis and typically an increased serum IgG4 concentration, which may affect various organs. An 80-year-old woman with an otherwise unremarkable previous medical history was revealed to have a renal mass that was indicative of renal malignant carcinoma, for which a radical nephrectomy was performed. The mass was diagnosed as an IgG4-related inflammatory pseudotumor, which was histopathologically confirmed. The patient is currently well without evidence of IgG4-related disease at 3 months post-surgery, and did not require any additional therapy. PMID:27123131

    No members of the freshwater ascomycetes family Lindgomycetaceae have been associated with human infections. We isolated a mould (HKU35(T)) from the biopsy specimen of a patient with invasive foot infection and underlying immunoglobulin G4-related sclerosing disease. Histology showed florid, suppurative, granulomatous inflammation in the dermis, with central microabscess formation surrounded by epithelioid histiocytes, scattered giant cells, and a small number of lymphocytes. A Grocott stain revealed fungal elements in the center of the lesion. On Sabouraud glucose agar, HKU35(T) grew as gray and velvety colonies. Among the members of the family Lindgomycetaceae, HKU35(T) was the only strain that grew at 37°C. Microscopically, only sterile mycelia, but no fruiting bodies, were observed. HKU35(T) was susceptible to itrazonazole, voriconazole, and posaconazole, which was in line with the patient's clinical response to itraconazole treatment. Internal transcribed spacer and partial 18S nuclear rDNA (nrDNA), 28S nrDNA, β-tubulin gene, and EF1α gene sequencing showed that HKU35(T) occupied a unique phylogenetic position, most closely related to but distinct from members of the genera Clohesyomyces and Lindgomyces. We propose a new genus and species, Hongkongmyces pedis gen. et sp. nov., to describe this fungus, which belongs to the family Lindgomycetaceae in the orderPleosporales of class Dothideomycetes. This case also represents the first report of human infection associated with the family Lindgomycetaceae. PMID:25147085

    Type 1 auto-immune pancreatitis (type 1 AIP) is the pancreatic manifestation of IgG4-related systemic disease (IgG4-RD). This disease has recently been individualized and is characterized by elevated serum IgG4 levels and extrapancreatic lesions with common histologic characteristic: dense infiltration of lymphocytes, IgG4-positive plasma cells and storiforme fibrosis. Obliterative phlebitis is frequently detected. The pancreas is frequently involved in this disease. As approach to the pancreas for histological examination is generally difficult, AIP is diagnosed using a combination of clinical, serological, morphological and histopathological features. In pseudotumoral cases, AIP can be misdiagnosed as pancreatic cancer. Since AIP responds dramatically to steroid therapy, accurate diagnosis of AIP can avoid unnecessary laparotomy or pancreatic resection. We report here a case of a patient who underwent surgery for presumed pancreatic cancer. The final diagnosis was type 1 AIP.

    Tubulointerstitial nephritis (TIN) is the most common form of renal involvement in IgG4-related disease. It is characterized by a dominant infiltrate of IgG4-positive plasma cells in the interstitium and storiform fibrosis. Demonstration of IgG4-positive plasma cells is essential for diagnosis, but the number of IgG4-positive cells and the ratio of IgG4-positive/IgG-positive plasma cells may vary from case to case and depending on the methods of tissue sampling even in the same case. IgG4-positive plasma cells can be seen in TIN associated with systemic lupus erythematosus, Sjögren syndrome, or anti-neutrophil cytoplasmic antibody–associated vasculitis, which further add diagnostic confusion and difficulties. To have a more clear view of IgG4-TIN and to delineate differential points from other TIN with IgG4-positive plasma cell infiltrates, clinical and histological features of IgG4-TIN and its mimickers were reviewed. In the rear part, cases suggesting overlap of IgG4-TIN and its mimickers and glomerulonephritis associated with IgG4-TIN were briefly described. PMID:26666884

    The serine/threonine kinase Mst1 plays important roles in the control of immune cell trafficking, proliferation, and differentiation. Previously, we reported that Mst1 was required for thymocyte selection and regulatory T-cell functions, thereby the prevention of autoimmunity in mice. In humans, MST1 null mutations cause T-cell immunodeficiency and hypergammaglobulinemia with autoantibody production. RASSF5C(RAPL) is an activator of MST1 and it is frequently methylated in some tumors. Herein, we investigated methylation of the promoter regions of MST1 and RASSF5C(RAPL) in leukocytes from patients with IgG4-related autoimmune pancreatitis (AIP) and rheumatoid arthritis (RA). Increased number of CpG methylation in the 5′ region of MST1 was detected in AIP patients with extrapancreatic lesions, whereas AIP patients without extrapancreatic lesions were similar to controls. In RA patients, we detected a slight increased CpG methylation in MST1, although the overall number of methylation sites was lower than that of AIP patients with extrapancreatic lesions. There were no significant changes of the methylation levels of the CpG islands in the 5′ region of RASSF5C(RAPL) in leukocytes from AIP and RA patients. Consistently, we found a significantly down-regulated expression of MST1 in regulatory T cells of AIP patients. Our results suggest that the decreased expression of MST1 in regulatory T cells due to hypermethylation of the promoter contributes to the pathogenesis of IgG4-related AIP. - Highlights: • Mst1 controls immune cells trafficking, cell proliferation and differentiation. • Autoimmune pancreatitis (AIP) is an idiopathic pancreatitis affecting multiple organs. • Decreased MST1 expression and increased CpG methylation of promoter of MST1 in AIP. • Slight increased CpG methylation of MST1 in rheumatoid arthritis patients. • MST1 contributes pathogenesis of IgG4-related AIP.

    A 61-year-old Japanese man with IgG4-related autoimmune pancreatitis was referred to our hospital because of perspiration during food intake. Abdominal computed tomography (CT) with contrast media revealed multiple mesenteric lymphadenopathies. An open surgical abdominal biopsy and subsequent histopathological analysis revealed abnormally large lymphoid cells that were negative for CD3, CD5, and c-myc and positive for CD20 and bcl-2, leading to a diagnosis of diffuse large B-cell lymphoma. Here, we discuss the risk of malignancies, particularly malignant lymphoma in patients with IgG4-related disease. The importance of pathological analysis to reach the appropriate diagnosis in such cases should be emphasized. PMID:27549673

    2016-01-01

    Summary IgG4-related disease (IgG4-RD) is a rare but increasingly recognised condition, emerging as a clinical entity following the observation of the associations of autoimmune pancreatitis. IgG4-RD is characterised by extensive infiltration of IgG4-positive plasma cells into multiple organs and raised serum IgG4 levels. Clinical manifestations of IgG4 disease classically include autoimmune pancreatitis, lacrimal or salivary gland infiltration (formerly known as Mikulicz disease) and retroperitoneal fibrosis. More rarely, IgG4 disease can cause pituitary hypophysitis. Although most frequently described in middle-aged males, the epidemiology and pathogenesis of the disease remain largely undefined. Nevertheless, an understanding of the wide variety of clinical manifestations of this multi-system condition is undeniably important given the often excellent outcomes following treatment. We describe an unusual presentation of IgG4 disease with isolated diabetes insipidus secondary to pituitary hypophysitis. The patient in question subsequently developed chest pain secondary to mediastinal lymphadenopathy and tubulo-interstitial nephritis leading to renal dysfunction. He was successfully treated with oral steroids and had regular follow-up, and remains well at follow-up 2 years later. Learning points IgG4 disease, although rare, is increasing in prevalence largely due to increased recognition of its clinical manifestations, including autoimmune pancreatitis, lacrimal or salivary gland infiltration, retroperitoneal fibrosis and, more rarely, lymphocytic hypophysitis presenting as diabetes insipidus. IgG4 disease is highly treatable, and symptoms may show complete resolution with administration of steroids, highlighting the importance of correct and timely diagnosis. Causes of lymphocytic hypophysitis are varied and not distinguishable radiologically. Given the difficulty in biopsying the pituitary, careful attention must be paid to the systemic clinical presentation to

    IgG4-related tubulointerstitial nephritis (IgG4-TIN) is the most common renal manifestation of IgG4-related kidney disease (IgG4-RKD) and may cause acute or chronic renal dysfunction. Imaging often shows heterogeneous densities in the kidneys, such as a mass or multiple nodules. Serology usually demonstrates high levels of serum IgG4 and total IgG. Most patients have other organs involvement by IgG4 related disease. Although lymphadenopathy is frequently observed in patients with IgG4-TIN, it is rarely presented as the only extrarenal lesion. Herein, we present a rare case of IgG4-TIN associated with only lymphadenopathy and without elevated serum IgG4 or renal imaging abnormalities. A 61-year-old Chinese man was admitted to our hospital with seven months history of generalized lymphadenopathy and five months history of renal dysfunction. His renal imaging was normal. He had no current or previous clinical, radiographic, and/or histologic evidence of other organ involvement except for the lymphadenopathy. Renal biopsy indicated plasma cell-rich TIN with an increased number of IgG4-positive plasma cells and storiform fibrosis. Repeated lymph nodes biopsy revealed IgG4-related lymphadenopathy. However, he did not have elevated serum IgG4 or total IgG levels. Oral prednisone therapy improved his renal function and lymphadenopathy. These findings supported our final diagnosis of IgG4-TIN. Clinicians should be aware of this condition and steroid therapy should be considered for such patients. An early diagnosis and appropriate therapy can induce remission and preserve renal function.

    Objective To perform a population-based analysis to compare the complications and cost of laparoscopic and robotically assisted adnexal surgery. Methods A nationwide database was utilized to analyze the use and outcomes of robotically assisted adnexal surgery from 2009–2012. Multivariable mixed effects regression models were developed to examine predictors of use of robotic surgery. After propensity score matching, complications and cost were compared between robotically assisted and laparoscopic surgery. Results 87,514 women were identified. From 2009 to 2012, performance of robotic-assisted oophorectomy increased from 3.5% (95% CI, 3.2–3.8%) to 15.0% (95% CI, 14.4–15.6%), while robotically assisted cystectomy rose from 2.4% (95% CI, 2.0–2.7%) to 12.9% (95% CI, 12.2–13.5%). The overall complication rate was 7.1% (95% CI, 4.0–10.2%) for robotically assisted vs. 6.0% (95% CI, 2.9–9.1%) for laparoscopic oophorectomy (OR=1.20; 95% CI, 1.00–1.45) (P=0.052). Robotic-assisted oophorectomy was associated with a higher rate of intraoperative complications (3.4% vs. 2.1%, OR=1.60; 95% CI, 1.21–2.13). The overall complication rate was 3.7% (95% CI −0.8–8.2%) after robotically assisted versus 2.7% (95% CI, −1.8–7.2%) for laparoscopic cystectomy (OR=1.38; 95% CI, 0.95–1.99). The intraoperative complication rate was higher for robotically assisted cystectomy (2.0% vs. 0.9%, OR=2.40; 95% CI, 1.31–4.38). Compared to laparoscopy, robotically assisted oophorectomy was associated with $2504 (95% CI, $2356–$2652) increased total costs and robotically assisted cystectomy $3310 (95% CI, $3082–$3581) higher costs. Conclusion Use of robotically assisted adnexal surgery increased rapidly. Compared to laparoscopic surgery, robotically assisted adnexal surgery is associated with substantially greater costs and a small, but statistically significant, increase in intraoperative complications.

    Purpose: To describe six cases of anterior orbital and adnexal amyloidosis and to report on proteomic analysis to characterize the nature of amyloid in archived biopsies in two cases. Materials and Methods: The clinical features, radiological findings, pathology, and outcome of six patients with anterior orbit and adnexal amyloidosis were retrieved from the medical records. The biochemical nature of the amyloid was determined using liquid chromatography/mass spectroscopy archived paraffin-embedded tissue in two cases. Results: Of the six cases, three had unilateral localized anterior orbit and lacrimal gland involvement. Four of the six patients were female with an average duration of 12.8 years from the time of onset to presentation eyelid infiltration by amyloid caused ptosis in five cases. CT scan in patients with lacrimal gland involvement (n = 3) demonstrated calcified deformable anterior orbital masses and on pathological exmaintionamyloid and calcific deposits replaced the lacrimal gland acini. Ptosis repair was performed in three patients with good outcomes. One patient required repeated debulking of the mass and one patient had recurrenct disease. Proteomic analysis revealed polyclonal IgG-associated amyloid deposition in one patient and AL kappa amyloid in the second patient. Conclusion: Amyloidosis of the anterior orbit and lacrimal gland can present with a wide spectrum of findings with good outcomes after surgical excision. The nature of amyloid material can be precisely determined in archival pathology blocks using diagnostic proteomic analysis. PMID:24014979

    A 60-year-old man developed a rubbery thickening and erythema of his left lateral upper and lower eyelids and lateral canthus over several months. He was treated for an extended period of time for blepharitis and chalazia. Incisional biopsy eventually disclosed microscopically a hypercellular lymphoid population sparing the epidermis that surrounded adnexal structures and infiltrated between orbicularis muscle fibers. Immunohistochemically, the lesion was found to be composed of neoplastic, kappa-restricted B cells with an equal number of reactive T cells and small reactive follicles. The diagnosis was a primary cutaneous extranodal marginal zone B-cell lymphoma of the eyelid skin (EMZL). We review the distinguishing clinical, histopathologic, and immunohistochemical features of cutaneous EMZL and contrast those with EMZL of other ocular adnexal sites. Also offered is a differential diagnosis of cutaneous lymphomas of the eyelid skin, which are predominately T-cell lesions. PMID:26545575

    Background: Adnexal torsion (AT) is among the gynecological emergencies; more common in reproductive age, if diagnosed late, this can cause ovarian failure and infertility, but rarely thrombophlebitis and peritonitis. Despite these severe complications, preoperative diagnostic tests are not enough for early diagnosis. There are certain pieces of literature on the subject that reveal changes in mean platelet volume (MPV) values occur in inflammatory and ischemic diseases and that these changes have diagnostic and prognostic significance. However, there are no studies investigating this relationship with adnexal torsion. Aims: The aim of the study is to investigate the diagnostic and prognostic significance of the mean platelet volume value in the early diagnosis of patients with adnexal torsion. Study Design: Case-control study. Methods: Pre-operative demographic data, MPV, leukocyte count and neutrophils to lymphocytes (N/L) ratio in the blood samples of 51 patients, who were operated on preliminary adnexal torsion and diagnosed as adnexal torsion with a benign ovarian cyst (AT group) were retrospectively compared with those of 50 patients who were operated upon because of benign ovarian cysts and without torsion (control group) at this hospital between 2006 and 2014. Results: The mean MPV level was found to be 8.1 (7.1–10.7) fL in the AT group and 7.9 (6.6–10.2) fL in the control group; no statistically significant difference was found between the groups (p>0.05). Leukocyte count and N/L ratio in the AT group were, on average, 12×103/mm3 and 82% respectively and in control group; they were, on average, 7.2×103/mm3 and 59%, respectively. A statistically significant increase was found in the leukocyte count and N/L ratio of the AT group compared to the control group (p<0.001). The platelet count in the AT group was, on average, 253×103/mm3 and in the control group it was, on average, 280×103/mm3; no statistically significant difference was detected between

    Ocular and adnexal congenital disorders are those that manifest at birth and could involve single or multiple tissues. Several abnormalities have been reported in literature affecting reptilian ocular and/or adnexal tissues. The objectives of this review are: (i) review those disorders previously reported in reptile literature; (ii) present new cases; (iii) provide a basic classification of them according to the moment of occurrence and (iv) indirectly, encourage the clinician dealing with these cases to go further in their diagnosis. The authors consider that categorizing ocular and adnexal congenital disorders could help the clinician to deal with them. The categorization of these disorders required an intense review of cases previously reported in literature and allows the authors suspect that some of them could not have been accurately diagnosed according to the definitions of the anomalies and/or not accurately described. The authors consider that ocular and adnexal congenital disorders could have been underestimated in reptiles and further studies could be helpful to promote the description of new disorders and to expand the knowledge about those previously reported. The review will first describe abnormalities reported during organogenesis (describing possible etiopathogenesis, cases reported, an approach to their diagnosis and recommended therapeutic options).Then a mention of the ocular disorders occurring after organogenesis is made. These disorders are divided when possible in those affecting all or most part of the globe and those affecting only specific tissues (surface ectoderm, neurocrest and mesenchyma and neuroectoderm).

    TMEM207 was first characterized as being an important molecule for the invasion activity of gastric signet-ring cell carcinoma cells. In order to unravel the pathological properties of TMEM207, we generated several transgenic mouse lines, designated C57BL/6-Tg (ITF-TMEM207), in which murine TMEM207 was ectopically expressed under a truncated (by ~200 bp) proximal promoter of the murine intestinal trefoil factor (ITF) gene (also known as Tff3). Unexpectedly, a C57BL/6-Tg (ITF-TMEM207) mouse line exhibited a high incidence of spontaneous intradermal tumors with histopathological features that resembled those of various human cutaneous adnexal tumors. These tumors were found in ~14% female and 13% of male 6- to 12-month-old mice. TMEM207 immunoreactivity was found in hair follicle bulge cells in non-tumorous skin, as well as in cutaneous adnexal tumors of the transgenic mouse. The ITF-TMEM207 construct in this line appeared to be inserted to a major satellite repeat sequence at chromosome 2, in which no definite coding molecule was found. In addition, we also observed cutaneous adnexal tumors in three other C57BL/6-Tg (ITF-TMEM207) transgenic mouse lines. We believe that the C57BL/6-Tg (ITF-TMEM207) mouse might be a useful model to understand human cutaneous adnexal tumors. PMID:25305140

Although OALs are usually primary tumors, secondary involvement of the ocular adnexae by systemic lymphoma is also possible. The clinical and radiological features of OAL are non-specific. Thorough morphological evaluation, aided by immunostaining, cytogenetic studies and molecular testing, are necessary for accurate diagnosis. PMID:26972223

    Ocular adnexal amyloidosis is characterized by amyloid deposition within the deep connective tissue layers of the eyelids, conjunctiva, and anterior orbit. Management of advanced cases has traditionally been unsatisfactory, with either no surgery offered because of fear of hemorrhage or an en bloc resection performed of the entire involved area. We present two cases of advanced periorbital amyloidosis successfully managed by preserving the anatomic planes of the eyelids and meticulously debulking the deposits with a spooned curette. Lax eyelid tendons and aponeuroses were simultaneously repaired, and no sacrifice of eyelid tissues was necessary. One patient remained asymptomatic for 2 years after surgery before developing early reaccumulation in the lower eyelids. The other patient required additional eyelid debulking and ptosis revision 8 months after surgery, but was in stable condition at follow-up 2 years after surgery. This technique offers safe, easily repeatable, nondestructive treatment for advanced periocular amyloidosis.

    Background Adnexal torsion can be a life-threatning condition in pregnancy, while the risk of late diagnosis is increased, in second and third trimester in particular. Laparoscopy is an effective approach in diagnosis and treatment of adnexal torsion. However, entry to abdomen may be challenging in more advanced pregnancies. Case report Herein, we report a case of adnexal torsion during 20th week of twin pregnancy, which was detorsioned laparoscopically. The woman delivered healthy infants at her 36th week of pregnancy. Discussion Adnexal torsion as a cause of acute abdomen may be kept in mind in pregnants, even if there is no predisposing factor. Laparoscopy may be performed safely in 2nd trimester for acute abdomen. PMID:27129134

    We report an eccrine acrospiroma, on the cheek of a 29-year-old female, in which the presence of abundant mucinous (goblet cell) metaplasia closely mimicked a primary mucoepidermoid carcinoma. To determine the frequency of mucinous differentiation in benign adnexal sweat gland tumors, we evaluated sixty-five cases in hematoxylin and eosin stained sections for the presence of goblet cells and sixty of these for mucicarmine positivity. Goblet cell metaplasia was seen in 3 of 12 acrospiromas, 1 of 8 mixed tumors, and in 1 of 9 cases of syringocystadenoma papilliferum. All goblet cells were positive for mucicarmine, except in one case of acrospiroma, where goblet cells were not detected on the section stained with mucicarmine. In addition, intracellular mucin, inclusive of goblet cells, was seen in 5 of 12 acrospiromas, 1 of 11 poromas, 5 of 8 mixed tumors, 3 of 13 spiradenomas, 1 of 5 cylindromas, 3 of 9 cases of syringocystadenoma papilliferum and 1 of 3 nipple adenomas. The majority of the tumors had both extracellular mucicarmine positivity (40 of 60) and luminal mucicarmine positivity (39 of 60). We conclude that mucinous differentiation in sweat gland tumors, as defined by the presence of goblet cells and/or intracellular mucicarmine positivity, is common and does not indicate aggressive behavior. Mucinous differentiation in benign sweat gland tumors should not be confused with more aggressive mucoepidermoid carcinomas of salivary gland origin or adenosquamous carcinoma.

    We present a rare case of malignant epithelial neoplasm of the appendix, an uncommon disorder encountered in clinical practice, which poses a variety of diagnostic and therapeutic challenges. We report a particular case in which the appendix was abnormally located in the pelvis, mimicking an adnexal mass. Therefore, it was difficult to make the preoperative diagnosis on clinical examination, imaging studies and laboratory tests and we discovered the lesion during the diagnostic laparoscopy. No lymphadenopathy or mucinous ascites were found. The case was completely handled via the laparoscopic approach keeping the appendix intact during the operation. The frozen section, the detailed histopathology overview as well as multiple immunostaining with a complex panel of markers report diagnosed a low-grade appendiceal mucinous neoplasm (LAMN) with no invasion of the wall. No adjuvant therapy was considered needed. At a one-year follow-up oncological assessment, the patient was free of disease. In women with cystic mass in the right iliac fossa an appendiceal mucocele should be considered in the differential diagnosis. Laparoscopic appendectomy can represent an adequate operation for the appendiceal mucinous neoplasm if the histological report is clear and surgical precautionary measures are taken.

    Introduction: Single-site laparoscopy is gaining acceptance in many surgical fields including gynecology. The purpose of this report is to demonstrate the technique and outcome for removing a large adnexal mass through a single site. Case Description: A 41-y-old female was referred to gynecology oncology for increased abdominal girth for 3 mo. An ultrasound confirmed a benign-appearing, 37-cm left adnexal mass. The mass was removed through a single-site laparoscopic incision with the aid of drainage and a morcellator. The operating time was 84 min. The patient was discharged 2 h and 35 min later with full return to normal activity in 5 d. Conclusion: Large, benign-appearing adnexal masses can be managed safely with superior cosmetic results using single-site laparoscopy. PMID:23925036

    Two unusual Carney complex patients are described. In one of them, several cutaneous biopsies revealed myxoid lesions that were rather more close to authentic adnexal neoplasms with myxoid stroma than to a "myxoma with an epithelial component." These included lesions resembling trichofolliculoma, infundibular cyst, and trichodiscoma. Additionally, 1 soft tissue myxoma was unique in the sense that it greatly resembled a cardiac myxoma, begging the question whether this could represent an embolus from the patient's cardiac myxoma. Given the large size and complexity and heterogeneity of the cutaneous lesions, the authors suggest that these may represent authentic cutaneous neoplasms accompanied by myxoid stroma and not adnexal elements induced by the stroma. However, the latter mechanism is well recognized and demonstrated by our second patient in whom adnexal-type elements in the cutaneous lesion were clearly induced by the myxoid stroma but were unusually complex by manifesting panfollicular and also sebaceous differentiation.

    All gynecologists are faced with ovarian tumors on a regular basis, and the accurate preoperative diagnosis of these masses is important because appropriate management depends on the type of tumor. Recently, the International Ovarian Tumor Analysis (IOTA) consortium published the Assessment of Different NEoplasias in the adneXa (ADNEX) model, the first risk model that differentiates between benign and four types of malignant ovarian tumors: borderline, stage I cancer, stage II-IV cancer, and secondary metastatic cancer. This approach is novel compared to existing tools that only differentiate between benign and malignant tumors, and therefore questions may arise on how ADNEX can be used in clinical practice. In the present paper, we first provide an in-depth discussion about the predictors used in ADNEX and the ability for risk prediction with different tumor histologies. Furthermore, we formulate suggestions about the selection and interpretation of risk cut-offs for patient stratification and choice of appropriate clinical management. This is illustrated with a few example patients. We cannot propose a generally applicable algorithm with fixed cut-offs, because (as with any risk model) this depends on the specific clinical setting in which the model will be used. Nevertheless, this paper provides a guidance on how the ADNEX model may be adopted into clinical practice.

    Immunoglobulin G4 (IgG4)-related sclerosing disease is a systemic disease characterized by extensive IgG4-positive plasma cells and T-lymphocyte infiltration in various organs. We described the imaging findings of an IgG4-related inflammatory pseudotumor in the urethra. The urethral mass showed isoattenuation on unenhanced CT images, delayed enhancement on enhanced CT images, iso- to slight hyper-intensity on T1 and T2 weighted magnetic resonance images, diffusion restriction on diffusion weighted images, and heterogeneously low echogeneity on ultrasonography.

    Context: Elderly patients with visual loss often have age-related macular degeneration, diabetic retinopathy, glaucoma, and cataract as common causes of visual loss. Other less common etiologies should be considered, especially in those presenting with systemic associations. Case Report: The patient discussed in our review is an 80-year-old female, with a history of diabetic retinopathy and macular degeneration who presented with a sudden deterioration of vision. While this was initially attributed to diabetic retinopathy, she was eventually noted to have a salmon patch lesion in her conjunctiva, diagnosed on biopsy to be a diffuse large B-cell lymphoma. Conclusion: Because of the significant rate of disseminated disease among patients with lymphomas in the orbit that carries a worse prognosis, early diagnosis is essential to promote better overall survival of these patients. We describe here a patient diagnosed with conjunctival lymphoma associated with pronounced visual loss and review the literature on this subject. PMID:27011948

    Whilst the outcomes for patients with ovarian cancer clearly benefit from centralised, comprehensive care in dedicated cancer centres, unfortunately the majority of patients still do not receive appropriate specialist treatment. Any improvement in the accuracy of current triaging and referral pathways whether using new imaging tests or biomarkers would therefore be of value in order to optimise the appropriate selection of patients for such care. An analysis of current evidence shows that such tests are now available, but still await recognition, acceptance and widespread adoption. It is therefore to be hoped that present guidance relating to the classification of ovarian masses will soon become more “evidence-based”. These promising tests include the International Ovarian Tumour Analysis (IOTA) LR2 model and ultrasound-based Simple Rules (SR). Based on a comprehensive recent meta-analysis both currently offer the optimal “evidence-based” approach to discriminating between cancer and benign conditions in women with adnexal tumours needing surgery. LR2 and SR are reliable tests having been shown to maintain a high sensitivity for cancer after independent external and temporal validation by the IOTA group in the hands of examiners with various levels of ultrasound expertise. They also offer more accurate triage compared to the existing Risk of Malignancy Index (RMI). The development of the IOTA ADNEX model represents an important step forward towards more individualised patient care in this area. ADNEX is a novel test that enables the more specific subtyping of adnexal cancers (i.e. borderline, stage 1 invasive, stage II-IV invasive, and secondary metastatic malignant tumours) and shares similar levels of accuracy to IOTA LR2 and SR for basic discrimination between cancer and benign disease. The IOTA study has made significant progress in relation to the classification of adnexal masses, however what is now needed is to see if these or new diagnostic tools

    Dear Editor, Apocrine hidradenoma is a rare benign adnexal tumor related to the more common poroma, as they both originate from sweat glands. Hidradenoma usually has an eccrine differentiation, but an apocrine differentiation is possible. Due to its rarity and non-specific clinical appearance it is difficult to differentiate it from other malignant cutaneous lesions. In this challenging task, dermatoscopy could be particularly helpful to better describe, recognize, and differentiate these lesions. Unfortunately, the literature offers only few dermatoscopic descriptions of this rare cutaneous neoplasm. A 70-year-old woman in fair general condition was referred to our Department for an asymptomatic 10×8 mm single nodule on her left scapula. This nodule was red, dome shaped, well circumscribed, firm, and mildly tender (Figure 1). The patient reported that it had been present since approximately 7 months. The lesion was neither painful nor itchy and there was no bleeding. A skin examination did not show any other lesions with the same features or other suspicious lesions. Dermatoscopy revealed milky-pinkish areas with dotted vessels, linear-irregular vessels, and hairpin vessels: some of these aspects can also be found in amelanotic melanoma (1). There were also homogeneous blue areas similar to lacunae, characteristic but not exclusive to vascular or sarcomatous neoplasms and basal cell carcinoma (1,2). Furthermore, small ulcerations covered by an amber crust were identified, which can usually be found in basal cell carcinoma. Regarding the background of the lesion, we noticed peculiar, translucent, pinkish, soft, large lobular areas (Figure 2). On the basis of this analysis, we suspected an atypical presentation of a basal cell carcinoma, an amelanotic melanoma, or a sarcomatous skin neoplasm. A metastasis of an unknown solid tumor was also taken into consideration. The histological examination revealed an adnexal neoplasm and specifically an apocrine hidradenoma

    Adnexal masses can be found in 0.19 to 8.8% of all pregnancies. Most masses are functional and asymptomatic and up to 70% resolve spontaneously in the second trimester. The main predictors of persistence are the size (>5 cm) and the imagiological morphocomplexity. Those that persist carry a low risk of malignancy (0 to 10%). Most malignant masses are diagnosed at early stages and more than 50% are borderline epithelial neoplasms. Ultrasound is the preferred method to stratify the risk of complications and malignancy, allowing medical approach planning. Pregnancy and some gestational disorders may modify the levels of tumor markers, whereby their interpretation during pregnancy should be cautious. Large masses are at increased risk of torsion, rupture, and dystocia. When surgery is indicated, laparoscopy is a safe technique and should ideally be carried out in the second trimester of pregnancy. PMID:27119043

    Purpose: Aim of the study was to investigate the incidence, progress, management and outcome of adnexal torsion after controlled ovarian hyperstimulation in embryo transfer cycles. Materials and Method: A retrospective analysis was done of 1007 patients of a private IVF centre. The literature on adnexal torsion is reviewed. Results: In the literature, the incidence of adnexal torsion after assisted reproductive technologies (ART) is given as around 0.2 %. A significant increase of up to 33 % has been reported for cases with additional ovarian hyperstimulation syndrome (OHSS) and in pregnant women. In our retrospective analysis of 1007 women (incidence 0.46 %) with 1411 fresh embryo transfer cycles, we found an incidence of 0.35 % per embryo transfer. All adnexal torsions were treated by laparoscopic derotation to preserve fertility. All 5 cases with torsion were pregnant, 2 patients had mild OHSS. We recorded 3 term deliveries, 1 induced abortion for sirenomelia, and 1 missed abortion. Conclusion: Adnexal torsion must be kept in mind after hyperstimulation and embryo transfer, especially when pregnancy or OHSS is also present. With early diagnosis, it should be possible to preserve fertility using laparoscopic derotation. PMID:25258463

    Female adnexal tumor of probable Wolffian origin (FATWO) is a rare disease entity that arises from the mesonephric duct system. FATWO is different than other gynecological cancers in terms of embryology. Here, we describe the case of a 52-year-old woman with malignant FATWO. The patient underwent explorative laparotomy and surgical staging after a frozen section revealed malignancy. Detailed examination of the pathologic findings were consistent with FATWO. Counseling and further testing were provided to the patient to assess the risk of germline mutation and epigenetic change. An O-6-methylguanine-DNA methyltransferase gene methylation test was positive, and all other tests were normal. This is the first study to report a case of O-6-methylguanine-DNA methyltransferase methylation with FATWO in Korea. PMID:27462603

    Adnexal hemangiomas are common in infancy and childhood. They can be interesting to the ophthalmologist for two reasons: cosmetic and functional (the second, the more important). By their natural history, they can produce serious visual consequences by producing refractive or stimulus-deprivation amblyopia. The management of adnexal hemangiomas is a challenge. The accepted method is most instances is corticosteroid therapy. This is administered either by local, intralesional, or systemic routes; the first is preferred. Steroid therapy can cause systemic and local side effects. Furthermore, a rebound effect can occur with this type of therapy. We present the cases of 12 patients with adnexal hemangiomas treated with steroids. These patients are reviewed, with emphasis on their responses and the complications of steroid therapy.

    Transumbilical laparoendoscopic single-site (LESS) surgery is a recent advancement in minimally invasive surgery. However, this procedure usually requires a specialized multichannel port for introducing the laparoscope and instruments under pneumoperitoneum. In an isobaric procedure, a wound retractor alone can conveniently be used for transumbilical single-site access. Fourteen isobaric LESS adnexal surgeries including 1 emergency procedure with adnexal torsion were performed using multiple instruments inserted through the wound retractor. No extraumbilical incisions or conversion to standard multiple-port laparoscopic surgery were required. Port-related complications were not noted, and the cosmetic results were excellent. A wound retractor offers safe and reliable access for isobaric LESS adnexal surgery as an alternative to the current specialized port systems. PMID:20579942

    To our knowledge, patients with immunoglobulin G4-related sclerosing cholangitis (IgG4-SC) associated with autoimmune hemolytic anemia (AIHA) have not been reported previously. Many patients with IgG4-SC have autoimmune pancreatitis (AIP) and respond to steroid treatment. However, isolated cases of IgG4-SC are difficult to diagnose. We describe our experience with a patient who had IgG4-SC without AIP in whom the presence of AIHA led to diagnosis. The patient was a 73-year-old man who was being treated for dementia. Liver dysfunction was diagnosed on blood tests at another hospital. Imaging studies suggested the presence of carcinoma of the hepatic hilus and primary sclerosing cholangitis, but a rapidly progressing anemia developed simultaneously. After the diagnosis of AIHA, steroid treatment was begun, and the biliary stricture improved. IgG4-SC without AIP was thus diagnosed.

    Abstarct Immunoglobulin G4 (IgG4)-related disease is characterized by the typical histopathological features of a dense lymphoplasmacytic infiltrate rich in IgG4-positive plasma cells, a high ratio of IgG4- to IgG-positive cells, storiform fibrosis (cellular fibrosis organized in an irregular whorled pattern), obliterative phlebitis, and variable presence of eosinophils. The disease exhibits systemic involvement but very rarely involves the esophagus. A 33-year-old man was admitted to our hospital for evaluation of a 1-year history of progressive dysphagia. Neck imaging revealed a 3.9-cm mass in the cervical esophagus and multifocal calcified lymph nodes in the lower neck and mediastinum. Two previous tertiary hospitals failed to diagnose the patient's condition despite the use of ultrasound-guided needle biopsy of the neck tumor. We performed neck imaging studies, a flexible endoscopic swallowing study, high-resolution manometry, upper endoscopy, and a review of the previous pathologic slides. The patient was finally diagnosed with IgG4-related esophagitis and showed a good response to corticosteroid therapy. We herein report a rare case of dysphagia associated with IgG4-related disease and present a review of the literature. PMID:26683918

    Given the fact that infectious agents contribute to around 18% of human cancers worldwide, it would seem prudent to explore their role in neoplasms of the ocular adnexa: primary malignancies of the conjunctiva, lacrimal glands, eyelids, and orbit. By elucidating the mechanisms by which infectious agents contribute to oncogenesis, the management, treatment, and prevention of these neoplasms may one day parallel what is already in place for cancers such as cervical cancer, hepatocellular carcinoma, gastric mucosa-associated lymphoid tissue lymphoma and gastric adenocarcinoma. Antibiotic treatment and vaccines against infectious agents may herald a future with a curtailed role for traditional therapies of surgery, radiation, and chemotherapy. Unlike other malignancies for which large epidemiological studies are available, analyzing ocular adnexal neoplasms is challenging as they are relatively rare. Additionally, putative infectious agents seemingly display an immense geographic variation that has led to much debate regarding the relative importance of one organism versus another. This review discusses the pathogenetic role of several microorganisms in different ocular adnexal malignancies, including human papilloma virus in conjunctival papilloma and squamous cell carcinoma, human immunodeficiency virus in conjunctival squamous carcinoma, Kaposi sarcoma-associated herpes virus or human herpes simplex virus-8 (KSHV/HHV-8) in conjunctival Kaposi sarcoma, Helicobacter pylori (H. pylori,), Chlamydia, and hepatitis C virus in ocular adnexal mucosa-associated lymphoid tissue lymphomas. Unlike cervical cancer where a single infectious agent, human papilloma virus, is found in greater than 99% of lesions, multiple organisms may play a role in the etiology of certain ocular adnexal neoplasms by acting through similar mechanisms of oncogenesis, including chronic antigenic stimulation and the action of infectious oncogenes. However, similar to other human malignancies

    Cutaneous adnexal differentiation is well-recognized in benign mixed tumors occurring in cutaneous sites. The incidence of this histologic finding in salivary gland sites is not known. We sought to describe the incidence of cutaneous adnexal differentiation in benign mixed tumors of the palate, lip, and parotid gland. Benign mixed tumors of the palate (n=30), lip (n=13), and parotid gland (n=37) resected between 1980 and 2009 at a single academic medical institution were reviewed. All hematoxylin and eosin-stained sections containing neoplasm were reviewed by all authors including one dermatopathologist (S.H.O.). After confirming the diagnosis of benign mixed tumor, we evaluated for morphologic evidence of cutaneous adnexal differentiation and metaplastic epithelial and stromal changes. Chart review was conducted to obtain pertinent clinical information. Cutaneous adnexal differentiation was seen in 20% of palate and 39% of lip benign mixed tumors but in no parotid tumors. The most frequent features of cutaneous adnexal differentiation were tricholemmal differentiation (20% of palate and 39% of lip tumors), infundibulocystic structures (17% and 31%), and trichohyalin granules (13% and 31%). Sebaceous differentiation was seen in only one palate tumor. Varying amounts of stromal adipose were seen in 62, 37, and 22% of lip, palate, and parotid tumors. Osseous metaplasia was seen in one tumor from each site. When cutaneous adnexal differentiation occurs in salivary gland pleomorphic adenomas, it can present a diagnostic pitfall that must not be misinterpreted as carcinoma at biopsy, fine needle aspiration, or frozen section.

    The discrimination between benign and malignant adnexal masses in ultrasound images represents one of the most challenging problems in gynecologic practice. In the study described here, a new method for automatic discrimination of adnexal masses based on a neural networks approach was tested. The proposed method first calculates seven different types of characteristics (local binary pattern, fractal dimension, entropy, invariant moments, gray level co-occurrence matrix, law texture energy and Gabor wavelet) from ultrasound images of the ovary, from which several features are extracted and collected together with the clinical patient age. The proposed technique was validated using 106 benign and 39 malignant images obtained from 145 patients, corresponding to its probability of appearance in general population. On evaluation of the classifier, an accuracy of 98.78%, sensitivity of 98.50%, specificity of 98.90% and area under the curve of 0.997 were calculated.

    Mature teratoma of the ovary is the most common primary ovarian tumor accounting for 15% (10%-20%) of all ovarian neoplasms. Skin and skin adnexal structures are the most common elements identified in mature teratomas. Benign and malignant skin tumors can arise in ovarian teratomas, the most common being epithelial tumors. Melanocytic and adnexal tumors developing in a teratoma are rare and can be easily overlooked. We report 3 cases and review melanocytic and skin adnexal tumors encountered in ovarian teratomas.

    Ovarian cancer is among the most dreaded cancers since it is often found at a late stage where the opportunity for extended survival is poor. Ultrasound has been utilized in several ovarian cancer screening trials in asymptomatic women in order to detect ovarian cancer at early stages where survival rates are high. Efforts to improve screening for ovarian cancer are ongoing. While ovarian cancer screening in asymptomatic women is not recommended for clinical application currently, the care of women with adnexal masses found by ultrasound in clinical practice can benefit from close evaluation of the evidence obtained from large prospective ovarian cancer screening trials and by relating this evidence to recent advances in the understanding of different types of ovarian cancer. Post-menopausal women who have an adnexal mass discovered by ultrasound have a much higher risk of developing ovarian cancer than women with normal ultrasound. The preponderance of reported evidence indicates that ultrasound monitoring of an adnexal mass is safe, cost effective and can achieve an improved positive predictive value in detecting ovarian cancer when ovarian abnormalities resolve during surveillance. Proposals to arbitrarily discontinue ultrasound monitoring can negatively impact patient care and generate medical-legal actions, especially because there is no evidence to support safe discontinuation. In this review, we outline a rationale for continuing ultrasound surveillance of ovarian abnormalities.

    Purpose: To evaluate the role of fine needle aspiration (FNAC) as a diagnostic tool in cases of orbital and ocular adnexal masses. Cytological findings were correlated with histopathological diagnosis wherever possible. Methods: FNAC was performed in 29 patients of different age groups presenting with orbital and ocular adnexal masses. Patients were evaluated clinically and investigated by non-invasive techniques before fine needle aspiration of the masses. Smears were analyzed by a cytologist in all cases. Further, results of cytology were compared with the histopathological diagnosis. Results: The age of patients ranged from 1 to 68 years (mean: 29.79±19.29). There were 14 males and 15 females with a male to female ratio of 0.93:1. Out of 29 cases, 26 aspirates were cellular. Cellularity was insufficient in three (10.34%) aspirates. Out of 26 cellular aspirates, 11 were non-neoplastic while 15 were neoplastic on cytology. Subsequent histopathologic examination was done in 21/26 cases. Concordance rate of FNAC in orbital and ocular adnexal mass lesions with respect to the precise histologic diagnosis was 90%. Conclusion: When properly used in well-indicated patients (in cases where a diagnosis cannot be made by clinical and imaging findings alone), FNAC of orbital and periorbital lesions is an invaluable and suitable adjunct diagnostic technique that necessitates close cooperation between the ophthalmologist and cytologist. However, nondiagnostic aspirates may sometimes be obtained, and an inconclusive FNAC should not always be ignored. PMID:27621787

    Background The usefulness of T2*-weighted (T2*W) imaging for the detection of adnexal torsion has yet to be determined. Purpose To assess the usefulness of T2*W imaging for detecting and differentiating adnexal torsion. Material and Methods Eight patients with eight ovaries with torsion and 44 patients with 72 ovaries without torsion were included in this study. All patients underwent 1.5-T magnetic resonance imaging (MRI) including T2*W images. The frequency and distribution of hypointensity on T2*W images were compared between ovaries with torsion and ovaries without torsion. Results Hypointensity on T2*W images was significantly more frequent in ovaries with torsion than in ovaries without torsion (75% vs. 36%; P < 0.05). Among patients with hypointensity on T2*W images, the frequency of diffuse hypointensity was significantly higher in ovaries with torsion than in ovaries without torsion (83% vs. 0%; P < 0.01); whereas the frequency of focal hypointensity was significantly lower in ovaries with torsion than in ovaries without torsion (17% vs. 100%; P < 0.01). Conclusion The presence and distribution of hypointensity on T2*W images may play a supplementary role in the detection of adnexal torsion. PMID:27478621

    With careful preoperative assessment we have selected postmenopausal women who were believed to have benign adnexal masses and who were candidates for removal of these masses via operative laparoscopy. Criteria for inclusion were: postmenopausal status; cystic adnexal mass less than 10 cm. with distinct borders and without irregular solid parts or thick septa; CA 125<35 U/ml; and no contraindications for surgery. Sixty-one women were entered into the study. All of the masses were benign, including 27 serous cysts, 15 serous cystadenomas, 1 mucinous cystadenoma, 5 serous cystadenofibromas, 6 paratubal cysts, 3 retroperitoneal cysts, and 4 chronic hydrosalpinges. Fifty-eight patients had successful pelviscopic removal of their adnexal mass. Three patients (5%) required laparotomy. For patients managed by operative laparoscopy, mean operating time was 63 minutes, mean postoperative stay was 12 hours, and mean time to return to normal activity was 5.6 days. We conclude that the combination of CA 125 values and pelvic ultrasound can successfully predict benign masses in postmenopausal women, and removal of these masses by operative laparoscopy is acceptable in carefully selected women.

    Immunoglobulin G4 (IgG4)-related kidney disease (IgG4-KD) has recently been demonstrated to be an important part of IgG4-related sclerosing disease (IgG4-SD). However, since IgG4-KD is still relatively unfamiliar to radiologists and physicians as compared to IgG4-SD involving other organs, it could, therefore, be easily missed. In this article, we present a comprehensive pictorial review of IgG4-KD with regards to the imaging spectrum, mimickers, and clinicopathologic characteristics, based on our clinical experience with 48 patients during the past 13 years, as well as a literature review. Awareness of the broad imaging spectrum of IgG4-KD and differential diagnosis from its mimickers will thus facilitate its early diagnosis and treatment. PMID:26357500

    BACKGROUND Characterizing ovarian pathology is fundamental to optimizing management in both pre- and post-menopausal women. Inappropriate referral to oncology services can lead to unnecessary surgery or overly radical interventions compromising fertility in young women, whilst the consequences of failing to recognize cancer significantly impact on prognosis. By reflecting on recent developments of new diagnostic tests for preoperative identification of malignant disease in women with adnexal masses, we aimed to update a previous systematic review and meta-analysis. METHODS An extended search was performed in MEDLINE (PubMed) and EMBASE (OvidSp) from March 2008 to October 2013. Eligible studies provided information on diagnostic test performance of models, designed to predict ovarian cancer in a preoperative setting, that contained at least two variables. Study selection and extraction of study characteristics, types of bias, and test performance was performed independently by two reviewers. Quality was assessed using a modified version of the QUADAS assessment tool. A bivariate hierarchical random effects model was used to produce summary estimates of sensitivity and specificity with 95% confidence intervals or plot summary ROC curves for all models considered. RESULTS Our extended search identified a total of 1542 new primary articles. In total, 195 studies were eligible for qualitative data synthesis, and 96 validation studies reporting on 19 different prediction models met the predefined criteria for quantitative data synthesis. These models were tested on 26 438 adnexal masses, including 7199 (27%) malignant and 19 239 (73%) benign masses. The Risk of Malignancy Index (RMI) was the most frequently validated model. The logistic regression model LR2 with a risk cut-off of 10% and Simple Rules (SR), both developed by the International Ovarian Tumor Analysis (IOTA) study, performed better than all other included models with a pooled sensitivity and specificity

    A prospective study was made of 105 consecutive patients admitted to one department of obstetrics and gynaecology for surgery for adnexal masses. The objective was to investigate if CA 125 level is measurable in the urine or saliva and to correlate these measurements with serum CA 125 level in patients presenting with adnexal masses. The final diagnosis and grouping of patients for analysis were based on histopathological examination of the adnexal masses. Serum, urine and salivary samples were collected simultaneously from all patients on the morning before surgery. CA 125 levels in each sample were determined in duplicate using Abbott CA 125-E1A monoclonal test kits (Abbott Laboratories, USA). The mean inter-assay variability was 10%. CA 125 was detectable in the serum, urine and saliva from all the patients and the concentration was highest in the saliva and lowest in urine. There were no discernible differences in the distributions of salivary CA 125 concentrations between patients with ovarian malignancies and those with benign ovarian cysts. In contrast, both serum and urinary CA 125 levels were significantly higher in the ovarian cancer group. There was no correlation in CA 125 concentrations between serum and urine, or between serum and saliva. For detection of ovarian malignancies, the sensitivity, specificity, and positive and negative predictive values for serum CA 125 measurement (> or = 35 U/mL) were 88.9%, 79.2%, 27.6% and 98.7 respectively. The corresponding figures for urinary CA 125 measurement (> or = 10 U/mL) were 88.9%, 66.7%, 19.5% and 98.4% respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

    Abstract To investigate clinical and radiological features of IgG4-related disease (IgG4-RD) patients with intrathoracic involvement. A prospective cohort study was performed and IgG4-RD patients were enrolled from January 2011 to March 2015 in Peking Union Medical College Hospital, in which the clinical and radiological characteristics of IgG4-RD patients with intrathoracic involvement were summarized. Out of total 248 cases with IgG4-RD, 87 cases had intrathoracic lesions, including 58 male cases and 29 female cases, with average age of 54.19 ± 13.80 years. Hilar and mediastinal lymphadenopathy were the most common manifestations of IgG4-related intrathoracic disease, accounting for 52.9% (46/87). Other imaging findings of pulmonary disease included: solid nodular (25.3%), round-shaped ground-glass opacities (9.2%), alveolar-interstitial type (20.7%), bronchovascular type (23.0%), pleural effusion (4.6%), and pleural nodules or thickening (16.1%). Only 27 patients presented with respiratory symptoms, including cough, breathless, chest pain, and asthma. Compared with patients without intrathoracic disease, IgG4-related intrathoracic disease had higher IgG4 and C-reactive protein level, and higher incidence of allergy, fever, and multi-organ involvement. Most of lung interstitial disease, mediastinal mass, and bronchial thickening were sensitive to corticosteroid and immunosuppressant therapy, while 36.3% (8/22) of solitary nodular lesions were unresponsive to treatment. Eight patients were on no treatment, with 5 cases remained stable, 2 patients improved spontaneously, and 1 patient was lost follow-up. Intrathoracic lesions are not rare in patients with IgG4-RD, involving bronchial thickening, nodules, ground glass opacity, pleural thickening/effusion, lymphadenopathy, etc. Efficacy of corticosteroid and immunosuppressant therapy were noted in most of patients with lung interstitial disease, mediastinal mass, and bronchial thickening.

    This work provides descriptive epidemiological data of malignant mucosal and uveal melanomas and adnexal skin carcinomas in Europe as defined as in the RARECARE project. We analysed 8669 incident cases registered in the period 1995-2002 by 76 population-based cancer registries (CRs), and followed up for vital status to 31st December 2003. Age-standardised incidence to the European standard population was obtained restricting the analysis to 8416 cancer cases collected by 64 not specialised CRs or with information available only for some anatomical sites. Period survival rates at 2000-2002 were estimated on 45 CRs data. Twenty-two CRs which covered the period 1988-2002 were analysed to obtain the 15-year prevalence (1st January 2003 as reference date). Complete prevalence was calculated by using the completeness index method which estimates surviving cases diagnosed prior to 1988 ('unobserved' prevalence). The expected number of new cases per year and of prevalent cases in Europe was then obtained multiplying the crude incidence and complete prevalence rates to the European population at 2008. We estimated 5204 new cases per year (10.5 per million) to occur in Europe, of which 48.7% were melanomas of uvea, 24.8% melanomas of mucosa and 26.5% adnexal carcinomas of the skin. Five-year relative survival was 40.6% and 68.9% for mucosal and uveal melanomas, respectively. Adnexal skin carcinomas showed a good prognosis with a survival of 87.7% 5 years after diagnosis. Northern Europe, United Kingdom (UK) and Ireland showed the highest 5-year survival rate for uveal melanomas (72.6% and 73.4%), while Southern Europe showed the lowest rate (63.7%). More than 50,000 persons with a past diagnosis of one of these rare cancers were estimated to be alive at 2008 in Europe, most of them (58.8%, n=29,676) being patients with uveal melanoma. Due to the good prognosis and high incidence of uveal melanomas, these malignancies are highly represented among the long-term survivors of

    Benign and malignant skin adnexal neoplasms, especially glandular lesions, show morphologically striking similarities to salivary gland tumors. On the other hand, histological and clinical differences are evident, and knowledge of their existence is important for adequate treatment and reliable prognostication. In this review similarities and differences of selected entities are briefly described and discussed. The following entities are reviewed: cylindroma (vs. membranous variant of basal cell adenoma), sebaceoma (vs. sebaceous adenoma), syringocystadenoma papilliferum (vs. sialadenoma papilliferum), chondroid syringoma (vs. pleomorphic adenoma), cutaneous myoepithelioma (vs. myoepithelioma of salivary glands), cutaneous malignant myoepithelioma (vs. malignant myoepithelioma of salivary glands), cutaneous adenoid cystic carcinoma (vs. adenoid cystic carcinoma of salivary glands), and mucinous eccrine carcinoma (vs. mucous carcinoma of salivary glands).

    When retroperitoneal leiomyosarcoma develops in pelvic cavity, it often presents similar symptoms and radiological findings to adnexal tumor, therefore obscures diagnostic approaches until an exploratory laparotomy is performed. We report an unusual presentation of retroperitoneal leiomyosarcoma mimicking an adnexal tumor with extremely elevated serum CA-19-9. Though the most of the prominent mass was removed during surgery, there was massive bleeding due to tearing of internal iliac vein while dissecting the ureter close to vessels. This case focuses on the significance of considering retroperitoneal tumor even if the mass is located in ovarian fossa and has highly elevated serum level of CA-19-9. And in attempt of tumor removal, the excision needs to be clean-cut without damaging nerves or vessels around the mass and avoid causing any prospective complications.

    Background: Single port laparoscopic surgery (SPLS) is an innovative approach that is rapidly gaining recognition worldwide. The aim of this study was to determine the feasibility and safety of SPLS compared to conventional laparoscopic surgery for the treatment of benign adnexal masses. Methods: In total, 99 patients who underwent SPLS for benign adnexal masses between December 2013 and March 2015 were compared to a nonrandomized control group comprising 104 conventional laparoscopic adnexal surgeries that were performed during the same period. We retrospectively analyzed multiple clinical characteristics and operative outcomes of all the patients, including age, body mass index, size and pathological type of ovarian mass, operative time, estimated blood loss (EBL), duration of postoperative hospital stay, etc. Results: No significant difference was observed between the two groups regarding preoperative baseline characteristics. However, the pathological results between the two groups were found to be slightly different. The most common pathological type in the SPLS group was mature cystic teratoma, whereas endometrioma was more commonly seen in the control group. Otherwise, the two groups had comparable surgical outcomes, including the median operation time (51 min vs. 52 min, P = 0.909), the median decreased level of hemoglobin from preoperation to postoperation day 3 (10 g/L vs. 10 g/L, P = 0.795), and the median duration of postoperative hospital stay (3 days vs. 3 days, P = 0.168). In SPLS groups, the median EBL and the anal exsufflation time were significantly less than those of the conventional group (5 ml vs. 10 ml, P < 0.001; 10 h vs. 22 h, P < 0.001). Conclusions: SPLS is a feasible and safe approach for the treatment of benign adnexal masses. Further study is required to better determine whether SPLS has significant benefits compared to conventional techniques. PMID:27231167

    Introduction. Pediatric surgeons often practice pediatric gynecology. The single-incision single-instrument (SISI) technique used for appendectomy is applicable in gynecologic surgery. Methods. We retrospectively analyzed the records of patients undergoing pelvic surgery from 2008 to 2013. SISI utilized a 12 mm transumbilical trocar and an operating endoscope. The adnexa can be detorsed intracorporeally or extracorporealized via the umbilicus for lesion removal. Results. We performed 271 ovarian or paraovarian surgeries in 258 patients. In 147 (54%), the initial approach was SISI; 75 cases (51%) were completed in patients aged from 1 day to 19.9 years and weighing 4.7 to 117 kg. Conversion to standard laparoscopy was due to contralateral oophoropexy, solid mass, inability to mobilize the adnexa, large mass, bleeding, adhesions, or better visualization. When SISI surgery was converted to Pfannenstiel, the principal reason was a solid mass. SISI surgery was significantly shorter than standard laparoscopy. There were no major complications and the overall cohort had an 11% minor complication rate. Conclusion. SISI adnexal surgery is safe, quick, inexpensive, and effective in pediatric patients. SISI was successful in over half the patients in whom it was attempted and offers a scarless result. If unsuccessful, the majority of cases can be completed with standard multiport laparoscopy.

    The etiology and pathogenesis of ocular adnexal extranodal marginal zone lymphoma (OAEMZL) are still unknown and the association with Chlamydophila psittaci (C. psittaci) has been shown in only some geographic regions. Herein we comprehensively examined the frequency of chromosomal translocations as well as CARD11, MYD88 (L265P) and A20 mutations /deletions in 45 C. psittaci negative OAEMZLs. t(14;18)(q32;q21) IGH-MALT1 and t(11;18)(q21;q21) API2-MALT1 were not detected in any of the analyzed tumors while 3 tumors harbored IGH translocations to an unidentified partner. CARD11 mutations were not found in all the analyzed tumors while MYD88 L265P mutation was detected in 3 (6.7%) tumors. A20 mutations and deletions were each detected in 7(15.6%) and 6(13.3%) of the tumors, respectively. Therefore, the observed genetic aberrations could account for the activation of NF-kB signaling pathway in only a minority of the cases. Further studies are needed to identify the molecular mechanisms underlying the pathogenesis of OAEMZL. PMID:23720088

    Ectopic pregnancy occurs when implantation of the blastocyst takes place in a site other than the endometrium of the uterine cavity. Uncommon implantation sites of ectopic pregnancy include the cervix, interstitial segment of the fallopian tube, scar from a prior cesarean delivery, uterine myometrium, ovary, and peritoneal cavity. Heterotopic and twin ectopic pregnancies are other rare manifestations. Ultrasonography (US) plays a central role in diagnosis of uncommon ectopic pregnancies. US features of an interstitial ectopic pregnancy include an echogenic interstitial line and abnormal bulging of the myometrial contour. A gestational sac that is located below the internal os of the cervix and that contains an embryo with a fetal heartbeat is indicative of a cervical ectopic pregnancy. In a cesarean scar ectopic pregnancy, the gestational sac is implanted in the anterior lower uterine segment at the site of the cesarean scar, with thinning of the myometrium seen anterior to the gestational sac. An intramural gestational sac implants in the uterine myometrium, separate from the uterine cavity and fallopian tubes. In an ovarian ectopic pregnancy, a gestational sac with a thick hyperechoic circumferential rim is located in or on the ovarian parenchyma. An intraperitoneal gestational sac is present in an abdominal ectopic pregnancy. Intra- and extrauterine gestational sacs are seen in a heterotopic pregnancy. Two adnexal heartbeats suggest a live twin ectopic pregnancy. Recognition of the specific US features will help radiologists diagnose these uncommon types of ectopic pregnancy.

Four weeks after surgery, the patient presented with grade IV peripheral neuropathy in the lower limbs; magnetic resonance imaging scan indicated an infiltrative lesion at D5. The local medical board decided on chemotherapy starting on the 19th week of gestation. The rest of the pregnancy period was uneventful and the patient had a cesarean section at 34 weeks of gestation and a live newborn with no complications. Unfortunately, four days after caesarean section, the patient died of a septic shock with respiratory focus. PMID:27602713

Unfortunately, four days after caesarean section, the patient died of a septic shock with respiratory focus.

    The pathogenesis of Chlamydophila psittaci-negative ocular adnexal extranodal marginal zone lymphomas (OAEMZLs) is poorly understood. OAEMZLs are monoclonal tumors expressing a biased repertoire of mutated surface immunoglobulins. Antigenic activation of the B-cell receptor (BCR) may have a role in the pathogenesis of these lymphomas. We have analyzed the reactivity of recombinant OAEMZL immunoglobulins. OAEMZL antibodies reacted with self-human antigens, as demonstrated by enzyme-linked immunosorbent assays, HEp-2 immunofluorescence and human protein microarrays. All the analyzed recombinant antibodies (rAbs) exhibited polyreactivity by comprehensive protein array antibody reactivity and some rAbs also demonstrated rheumatoid factor activity. The identity of several reactive antigens was confirmed by microcapillary reverse-phase high-performance liquid chromatography nano-electrospray tandem mass spectrometry. The tested rAbs frequently reacted with shared intracellular and extracellular self-antigens (for example, galectin-3). Furthermore, these self-antigens induced BCR signaling in B cells expressing cognate surface immunoglobulins derived from OAEMZLs. These findings indicate that interactions between self-antigens and cognate OAEMZL tumor-derived BCRs are functional, inducing intracellular signaling. Overall, our findings suggest that self-antigen-induced BCR stimulation may be implicated in the pathogenesis of C. psittaci-negative OAEMZLs. PMID:25676418

    Summary This is the case report of a 38-year-old woman who presented with a mass of the right broad ligament that was diagnosed as a female adnexal tumor of probable Wollfian origin (FATWO). The patient was treated with a simple mass excision. Three years after the excision, the patient presented with uterine bleeding. A total abdominal hysterectomy was advised. Intraoperative histologic consultation showed a poorly differentiated tumor on the surface of the left ovary. After extensive immunohistochemistry analysis and after reviewing the histology slides from the primary tumor, the final diagnosis was concluded to be recurrent FATWO on the surface of the ovary. C-kit immunohistochemistry was found to be strongly positive. Polymerase chain reaction amplification of C-kit genes on exons 9, 11, 13, and 17 and of PDGFR gene on exons 12 and 18 showed no mutational changes. Owing to the limited options in treating recurrent disease and the lack of prognostic factors for recurrence or metastasis, the patient was started on 400 mg of imatinib mesylate therapy for 6 months. In addition, the patient is undergoing continuous follow-up by computed tomographic imaging every 6 months. As chemotherapy and radiation therapy for recurrent or metastatic FATWO are most often unsuccessful, a molecular targeted therapy, such as tyrosine kinase inhibitor, could be considered. However, collective data are needed from multiple centers to determine its effectiveness in these patients. PMID:21464731

    Abstract: Initial investigations reported GATA3 to be a sensitive and relatively specific marker for mammary and urothelial carcinomas. Recently, GATA3 expression has been described in several other epithelial tumors. However, there has been only limited investigation of GATA3 expression in cutaneous epithelial tumors. The objective of this study was to examine the immunohistochemical expression of GATA3 in a wide variety of cutaneous epithelial neoplasms. GATA3 expression was evaluated in 99 benign and 63 malignant cutaneous epithelial tumors. GATA3 was consistently and usually strongly expressed in clear cell acanthoma, trichofolliculoma, trichoepithelioma, trichilemmoma, sebaceous adenoma, sebaceoma, apocrine hidrocystoma, apocrine tubular papillary adenoma, hidradenoma papilliferum, and syringocystadenoma papilliferum. Hidradenomas exhibited variable positive staining. Most poromas, syringomas, chondroid syringomas, cylindromas, and spiradenomas were negative or only focally and weakly positive. Focal staining was present in all pilomatrixomas. Thirteen of 14 basal cell carcinomas, 21 of 24 squamous carcinomas, and all 6 sebaceous carcinomas exhibited positive staining. The 1 apocrine carcinoma, both mucinous carcinomas, and 2 of 3 microcystic adnexal carcinomas also exhibited positive staining, whereas the 1 eccrine porocarcinoma and the 1 adenoid cystic carcinoma were negative. One of 11 Merkel cell carcinomas exhibited focal weak staining. Our findings demonstrate that GATA3 is expressed in a wide variety of benign and malignant cutaneous epithelial neoplasms. In addition to carcinomas of breast and urothelial origin and other more recently described GATA3-positive tumors, the differential diagnosis of a metastatic tumor of unknown primary origin that expresses GATA3 should also include a carcinoma of cutaneous epithelial origin.

  19. Basal cell carcinoma with thickened basement membrane: a variant that resembles some benign adnexal neoplasms.

    Because cutaneous basal cell carcinoma (BCC) is such a common malignancy, its unusual histologic manifestations are important. We identified a variant of BCC in which thickened basement membranes surround aggregations of neoplastic epithelial cells. Thickened basement membranes of similar appearance have previously been observed in benign cutaneous adnexal neoplasms, in basaloid monomorphic adenomas of the salivary gland and in other benign conditions, such as folliculocentric basaloid proliferation. We identified nine BCCs that otherwise met standard criteria, but which also had thick basement membranes surrounding some of the aggregations, and examined them by routine and histochemical staining. The cases included BCC with nodular, micronodular, and infiltrating patterns. Two neoplasms were composed largely of clear cells, suggesting, together with the thickened membranes, outer root sheath differentiation. CD34, which labels keratinocytes of the outer root sheath, marked only the epithelial cells of one of these cases. The thickened membranes were stained by periodic-acid Schiff with and without diastase (PAS-D) and by antibodies to type IV collagen and laminin, with slightly different staining patterns. Intraepithelial droplets within aggregations stained with PAS-D and type IV collagen antibodies. Thickened basement membranes therefore can occur in most of the common growth patterns of BCC. The absence of CD34 staining of epithelial cells in most cases makes it problematic at this time to prove that the thickened membranes indicate trichilemmal differentiation. BCC with thick basement membranes can closely mimic benign neoplasms, such as cylindroma and trichilemmoma, from which they can be distinguished in routinely stained sections. The presence of a continuous thick basement membrane around aggregates of epithelial cells does not in and of itself distinguish between benign and malignant cutaneous epithelial neoplasms.

    A 71-year-old woman presented with erythematous, nontender, bilateral hard palate nodules of 6-month duration. Biopsy showed collagenous sclerosis and a follicular lymphoplasmacytic infiltrate among the minor salivary glands. Immunoglobulin G (IgG) and IgG4 staining showed 280 IgG4(+) cells per high-power field and a ratio of IgG4(+) to IgG(+) cells of 0.8. The patient subsequently developed bilateral lacrimal gland and parotid gland enlargement associated with an increased serum IgG4 level of 3,031 mg/dL (≤ 135 mg/dL). Left lacrimal gland biopsy confirmed IgG4-related dacryoadenitis. The patient declined corticosteroid treatment for IgG4-related disease (IgG4-RD) and remained stable at 15 months after the first presentation. Spontaneous, partial resolution of the palatal lesion was observed during follow-up. IgG4-RD should be considered in the differential diagnosis of lymphoplasmacytic lesions of the hard palate.

    ABSTRACT Laparoscopy has become the standard surgery for the treatment of benign ovarian tumors. The aim of this study was to evaluate the appropriateness of laparoscopy for ovarian tumors, including those with malignant potential. A total of 487 patients with adnexal masses underwent laparoscopic surgery in Social Insurance Chukyo Hospital from January 2000 to December 2012.We reviewed 471 cases that fulfilled the criteria set for this study, and examined 10 cases with unexpected ovarian malignancy to analyze their preoperative diagnosis, second surgery, postoperative chemotherapy, and prognosis. The ages of the 471 patients ranged from 13 to 50 years, with a median of 31. Nulliparous patients numbered 321(68.1%).Of all, 436 patients mostly consisted of those with endometrioma, benign ovarian neoplasm or functional cyst. In all, we histologically identified 10 women with malignancy: 6 with borderline ovarian tumors (BOT), 2 with ovarian cancer, and 2 with histologically rare tumors (immature teratoma and granulosa cell tumor). All patients with BOT were diagnosed with a mucinous histology. Two patients underwent both second radical surgery (hysterectomy and contra- or bilateral salpingo-oophorectomy) and chemotherapies that consisted of CBDCA and PTX or DTX. Thus, 2 patients underwent staging procedures, but the remaining 8 cases did not. None of them had evidence of recurrences. With accurate staging and careful postoperative follow-up, laparoscopic surgery could be a feasible initial operation for patients with adnexal masses including early-stage ovarian malignancy.

    Objective To compare the operative outcomes, postoperative pain, and subsequent convalescence after laparoendoscopic single-site surgery (LESS) or conventional laparoscopic surgery for adnexal preservation. Study design From December 2009 to September 2010, 63 patients underwent LESS (n = 33) or a conventional laparoscopic surgery (n = 30) for cyst enucleation. The overall operative outcomes including postoperative pain measurement using the visual analog scale (VAS) were evaluated (time points 6, 24, and 24 hours). The convalescence data included data obtained from questionnaires on the need for analgesics and on patient-reported time to recovery end points. Results The preoperative characteristics did not significantly differ between the two groups. The postoperative hemoglobin drop was higher in the LESS group than in the conventional laparoscopic surgery group (P = 0.048). Postoperative pain at each VAS time point, oral analgesic requirement, intramuscular analgesic requirement, and the number of days until return to work were similar in both groups. Conclusion In adnexa-preserving surgery performed in reproductive-age women, the operative outcomes, including satisfaction of the patients and convalescence after surgery, are comparable for LESS and conventional laparoscopy. LESS may be a feasible and a promising alternative method for scarless abdominal surgery in the treatment of young women with adnexal cysts PMID:22448110

    Purpose: To evaluate the natural history, behavior of progression, prognostic factors, and treatment-related adverse effects of primary ocular adnexal mucosa-associated lymphoid tissue (MALT) lymphoma (POAML). Methods and Materials: Eighty-six patients with histologically proven stage I POAML treated with radiation therapy at National Cancer Center Hospital, Tokyo between 1990 and 2010 were retrospectively reviewed. The median age was 56 years (range, 18-85 years). The median dose administered was 30 Gy (range, 30-46 Gy). Seventy-seven patients (90%) were treated by radiation therapy alone. Results: The median follow-up duration was 9 years (range, 0.9-22 years). The 5- and 10-year overall survival (OS) rates were 97.6% and 93.5%, respectively, and no patients died of lymphoma. Patients with tumor sizes ≥4 cm showed a greater risk of contralateral relapse (P=.012). Six patients with contralateral relapse were seen and treated by radiation therapy alone, and all the lesions were controlled well, with follow-up times of 3 to 12 years. There was 1 case of local relapse after radiation therapy alone, and 3 cases of relapse occurred in a distant site. Cataracts developed in 36 of the 65 eyes treated without lens shielding and in 12 of the 39 patients with lens shielding (P=.037). Conclusions: The majority of patients with POAML showed behavior consistent with that of localized, indolent diseases. Thirty gray of local irradiation seems to be quite effective. The initial bilateral involvement and contralateral orbital relapses can be also controlled with radiation therapy alone. Lens shielding reduces the risk of cataract.

    Purpose: To evaluate the long-term treatment outcome and disease behavior of primary ocular adnexal MALT (mucosa-associated lymphoid tissue) lymphoma (POAML) after treatment with radiotherapy. Methods and Materials: Seventy-eight patients (42 male, 36 female) diagnosed with stage I POAML between 1991 and 2010 at Kobe University Hospital were included. The median age was 60 years (range, 22-85 years). The median radiation dose administered was 30.6 Gy. Rituximab-based targeted therapy and/or chemotherapy was performed in 20 patients (25.6%). Local control (LC), recurrence-free survival (RFS), and overall survival (OS) rates were calculated using the Kaplan-Meier method. Results: The median follow-up duration was 66 months. Major tumor sites were conjunctiva in 37 patients (47.4%), orbita in 29 (37.2%), and lacrimal glands in 12 (15.4%). The 5- and 10-year OS rates were 98.1% and 95.3%, respectively. The 5- and 10-year LC rates were both 100%, and the 5- and 10-year RFS rates were 88.5% and 75.9%, respectively. Patients treated with a combination of radiotherapy and targeted therapy and/or chemotherapy had a trend for a better RFS compared with those treated with radiotherapy alone (p = 0.114). None developed greater than Grade 2 acute morbidity. There were 14 patients who experienced Grade 2 morbidities (cataract: 14; retinal disorders: 7; dry eye: 3), 23 patients who had Grade 3 morbidities (cataract: 23; dry eye: 1), and 1 patient who had Grade 4 glaucoma. Conclusions: Radiotherapy for POAML was shown to be highly effective and safe for LC and OS on the basis of long-term observation. The absence of systemic relapse in patients with combined-modality treatment suggests that lower doses of radiation combined with targeted therapy may be worth further study.

    Therapeutic strategies for autoimmune liver diseases are increasingly established. Although proportionately uncommon, specialist centers have with time refined the best approaches for each disease, based on an improved understanding of the spectrum of presentation. The major treatment aims are to prevent end-stage liver disease and its associated complications. As a result of drugs such as ursodeoxycholic acid, predniso(lo)ne and azathioprine, both primary biliary cirrhosis and autoimmune hepatitis are now less commonly indications for liver transplantation. Unfortunately, the same inroads in treatment efficacy have as yet not been made for primary sclerosing cholangitis, although the recognition that a subset of patients may have a treatable secondary sclerosing cholangitis (IgG4 related) is helping a proportion. With better biological understanding, more specific interventions are expected that will benefit all those with autoimmune liver diseases. PMID:21180531

    Objective The purpose of this study was to compare clinical and surgical outcomes between laparo-endoscopic single-site (LESS) surgery and traditional multiport laparoscopic (TML) surgery for treatment of adnexal tumors. Methods Medical records were reviewed for patients undergoing surgery for benign adnexal tumors between January 2008 and April 2012 at our institution. All procedures were performed by the same surgeon. Clinical and surgical outcomes for patients undergoing LESS surgery using Glove port were compared with those patients undergoing TML surgery. Results A review of 129 patient cases undergoing LESS surgery using Glove port and 100 patient cases undergoing TML surgery revealed no significant differences in the baseline characteristics of the two groups. The median operative time was shorter in the LESS group using Glove port at 44 minutes (range, 19-126 minutes) than the TML group at 49 minutes (range, 20-196 minutes) (P=0.0007). There were no significant differences between in the duration of postoperative hospital stay, change in hemoglobin levels, pain score or the rate of complications between the LESS and TML groups. Conclusion LESS surgery showed comparable clinical and surgical outcomes to TML surgery, and required less operative time. Future prospective trials are warranted to further define the benefits of LESS surgery for adnexal tumor treatment. PMID:25264529

    Pulmonary-renal syndrome is a common and serious disorder with a broad differential diagnosis. We describe a case of a middle-aged man presenting with interstitial pulmonary disease and severe renal impairment caused by a hypocomplementemic immune-complex-mediated interstitial nephritis. Serum levels of IgG4 were elevated, and renal biopsy specimens revealed the presence of interstitial IgG4(+) plasma cells. There was a rapid improvement of both pulmonary and renal abnormalities after the initiation of corticosteroids. To our knowledge, this report is the first to show interstitial pulmonary disease in association with interstitial kidney disease as the predominant and presenting symptoms of IgG4-related disease.

    The aim of this study is to evaluate the efficacy of qualitative analysis of contrast-enhanced ultrasound (CEUS) in discrimination of adnexal masses which were undetermined by conventional ultrasound (US). A total of 120 patients underwent transabdominal CEUS. The initial enhancement time and intensity compared with the uterine myometrium, contrast agent distribution patterns and dynamic changes of enhancement were assessed. The sensitivity (Sen), specificity (Spe), positive predictive value (PPV), negative predictive value (NPV), accuracy (ACC) and Youden’s index were calculated for contrast variables. The gold standard was the histological diagnosis. There were 48 malignant tumors and 72 benign tumors. The enhancement features of malignant masses were different from benign ones. Earlier or simultaneous enhancement with inhomogeneous enhancement yielded the highest capability in differential diagnosis, and Sen, Spe, PPV, NPV, ACC, Youden’s index was 89.6%, 97.2%, 93.2%, 95.6%, 93.3%, and 0.88, respectively. The qualitative evaluation of CEUS is useful in the differential diagnosis of adnexal masses where conventional US is indeterminate. PMID:24736589

    Non-Hodgkin lymphoma of the orbit and ocular adnexa is the most common primary orbital malignancy. Treatments for low- (extra-nodal marginal zone and follicular lymphomas) and high-grade (diffuse large B-cell lymphoma) are associated with local and vision-threatening toxicities. High-grade lymphomas relapse frequently and exhibit poor survival rates. Despite advances in genomic profiling and precision-medicine, orbital and ocular adnexal lymphomas remain poorly characterized molecularly. We performed targeted next-generation sequencing profiling of 38 formalin-fixed, paraffin-embedded, orbital and ocular adnexal lymphomas obtained from a single-center using a panel targeting near-term, clinically-relevant genes. Potentially actionable mutations and copy-number alterations were prioritized based on gain- and loss-of function analyses, catalogued approved and investigational therapies. Of 36 informative samples, including marginal zone lymphomas (n=20), follicular lymphomas (n=9), and diffuse large B-cell lymphomas (n=7), 53% harbored a prioritized alteration (median=1, range 0–5/sample). MYD88 was the most frequently altered gene in our cohort, with potentially clinically-relevant hot-spot gain-of-function mutations identified in 71% of diffuse large B-cell and 25% of marginal zone lymphomas. Prioritized alterations in epigenetic modulators were common and included gain-of-function EZH2 and loss-of-function ARID1A mutations (14% of diffuse large B-cell lymphomas and 22% of follicular lymphomas contained alterations in each of these two genes). Single prioritized alterations were also identified in the histone methyltransferases KMT2B (follicular lymphoma) and KMT3B (diffuse large B-cell lymphoma). Loss-of-function mutations and copy-number alterations in the tumor suppressors TP53 (diffuse large B-cell and follicular lymphoma), CDKN2A (all subtypes), PTEN (diffuse large B-cell lymphoma), ATM (diffuse large B-cell lymphoma) and NF1 (diffuse large B-cell lymphoma

    Knowledge about fallopian tube disease is essential in the assessment of the pelvis in female patients. Primary and secondary changes in the tubes vary widely, regardless of whether associated changes in the ovaries are present. Ultrasonography is the initial technique in the study of adnexal disease because it is very sensitive and widely available; however, MRI is also very useful in this context because its high tissue resolution and anatomic detail make it more specific. The morphologic findings and the characteristics of the contents of the tubes on MRI enable a more accurate diagnosis or limit the differential diagnosis, helping to ensure that the most appropriate treatment is provided in each case.

    Since Sarles et al. [Sarles H, Sarles JC, Muratore R, Guien C. Chronic inflammatory sclerosis of the pancreas-an autonomous pancreatic disease? Am J Dig Dis 1961; 6: 688-698.] reported a case of pancreatitis associated with hypergammaglobulinemia, many cases have been described, which led to the current concept of "autoimmune pancreatitis (AIP)". Lymphoplasmacytic infiltration and fibrosis on histology together with elevated IgG levels or the presence of autoantibodies on laboratory examinations supported the concept of AIP. In recent years, based on histological and immunohistochemical examination of various organs of patients with AIP, a novel clinicopathological entity, IgG4-related slerosing disease, has been proposed. AIP is a systemic disease that is characterized by dense infiltration of IgG4-positive plasma cells and T lymphocytes in various organs. Clinical manifestations are related with pancreas dysfunction but other organs may be affected such as bile duct, gallbladder, salivary gland, retroperitoneum, kidney, lung and prostate. Increased serum IgG4 levels, the presence of several autoantibodies such as anti-carbonic anhydrase II antibodies (ACA-II), immunostaining IgG4 positive in pancreas tissue and a very good response to steroid therapy are useful for the diagnosis of AIP that can mimic pancreatic cancer.

    Background Pancreatitis and exocrine pancreatic insufficiency may occur as extraintestinal manifestations of inflammatory bowel disease. Recently, autoimmune pancreatitis and colitis have been described as presentations of IgG4-related disease. IgG4+ plasma cells have been identified in colon tissue from patients with refractory forms of inflammatory bowel disease. The presence of elevated serum/tissue levels of IgG4 and the frequency of exocrine pancreatic insufficiency in inflammatory bowel disease are still a source of controversy. Our aim was to investigate the meaning of elevated IgG4 levels in patients with inflammatory bowel disease. Methods A cross-sectional study analyzed 56 patients with a diagnosis of inflammatory bowel disease recruited by convenience sampling from two tertiary centers in Midwestern Brazil. All patients underwent fecal pancreatic elastase testing for detection of exocrine pancreatic insufficiency and serum IgG4 measurement. Findings were correlated with clinical and epidemiological data and disease activity. Results Elevated serum IgG4 levels were found in 10 patients, and were most frequent in ulcerative colitis (nine cases), with a prevalence ratio of 16.42 (95% CI: 3.32 - 79.58). Ten patients (10 of 56, 17.8%) were diagnosed with exocrine pancreatic insufficiency, which did not correlate with disease activity, and serum IgG4 levels. Conclusion Exocrine pancreatic insufficiency is prevalent in patients with inflammatory bowel disease, but it is not associated with elevated serum IgG4 levels. The high prevalence of elevated serum IgG4 in ulcerative colitis suggests that this parameter has potential for use as a diagnostic biomarker.

    Objective: Immunoglobulin G4 (IgG4) related sclerosing disease (RSD) of the paranasal sinuses is a rare lesion of dense lymphoplasmacytic tissue, with a high proportion of IgG4+ plasma cells. We presented a rare case of IgG4-RSD with isolated involvement of the paranasal sinuses in the absence of multiorgan involvement. Methods: A case report and comprehensive literature review. Results: To our knowledge, only 11 cases of IgG4-RSD with paranasal sinus involvement have been reported. Patients with IgG4-RSD commonly present with epistaxis and symptoms that mimic chronic rhinosinusitis, e.g., rhinorrhea, nasal obstruction, and facial pressure. On imaging, an expansive and erosive process is described. Surgery provides tissue for immunohistologic evaluation; however, there is a paucity of evidence about the direct extent of surgical resection or medical therapies. Postoperative steroids were typically started, although the regimen was not standardized. Conclusion: Few cases of paranasal sinus IgG4-RSD have been reported in the literature. Evidence-based recommendations regarding treatment and surveillance of paranasal sinus IgG4-RSD are lacking; however, most reports describe systemic steroids as the mainstay of treatment. This single subject analysis, with a review of previously reported cases adds to the expanding body of data related to this rare disorder.

    Objective IgG4-related disease is an emerging clinical entity which frequently involves tissue within the orbit. In order to appreciate the implications of IgG4 immunostaining, we analyzed gene expression and the prevalence of IgG4- immunostaining among subjects with orbital inflammatory diseases. Methods We organized an international consortium to collect orbital biopsies from 108 subjects including 22 with no known orbital disease, 42 with nonspecific orbital inflammatory disease (NSOI), 26 with thyroid eye disease (TED), 12 with sarcoidosis, and 6 with granulomatosis with polyangiitis (GPA). Lacrimal gland and orbital adipose tissue biopsies were immunostained for IgG4 or IgG secreting plasma cells. RNA transcripts were quantified by Affymetrix arrays. Results None of the healthy controls or subjects with TED had substantial IgG4 staining. Among the 63 others, the prevalence of significant IgG4-immunostaining ranged from 11 to 39% depending on the definition for significant. IgG4 staining was detectable in the majority of tissues from subjects with GPA and less commonly in tissue from subjects with sarcoidosis or NSOI. The detection of IgG4+ cells correlated with inflammation in the lacrimal gland based on histology. IgG4 staining tissue expressed an increase in transcripts associated with inflammation, especially B cell-related genes. Functional annotation analysis confirmed this. Conclusion IgG4+ plasma cells are common in orbital tissue from patients with sarcoidosis, GPA, or NSOI. Even using the low threshold of 10 IgG4+ cells/high powered field, IgG4 staining correlates with increased inflammation in the lacrimal gland based on histology and gene expression. PMID:25303270

    Mesenteric chylous cysts, also known as retroperitoneal chylomatous cysts, mesenteric lymphangiomas or chyloma of the mesentery, are extremely rare and their aspecific clinical presentation can mimic other diseases. In addition, imaging techniques, which are rarely helpful in the correct diagnosis, can demonstrate aspecific features. The Authors report the case of a 62-year-old woman admitted to the hospital for two incidental abdominal masses diagnosed during a yearly monitoring examination and considered to be large adnexal masses. The abdominal masses were removed at laparotomy. Both frozen section and final histopathological examination showed mesenteric chylous cysts. Mesenteric chylous cysts are usually a benign abdominal pathology. As illustrated by this case, even if they are extremely rare, they should be not underrated. The Authors review the literature, confirming the rarity of the disease and defining its characteristics.

    Pulmonary hyalinizing granulomas (PHGs) are unusual fibrosclerotic inflammatory lung lesions. The organ-based manifestations of the recently defined IgG4-related sclerosing disease typically show dense fibrosis and heavy lymphoplasmacytic infiltrates. IgG4-related sclerosing disease is also defined by increased serum IgG4 levels and increased tissue levels of IgG4-positive plasma cells. The morphologic features of PHG overlap with those seen in IgG4-related sclerosing disease, and this suggests that PHG may be a form of IgG4-related sclerosing disease. We present a case of a 51-year-old man with a history of sarcoidosis who presented with slowly enlarging pulmonary nodules. Histologic evaluation of one of the nodules yielded a diagnosis of PHG. Further investigation demonstrated both elevated serum IgG4 and elevated tissue IgG4-positive plasma cells in the PHG. In previous reports, lesions that are now considered part of IgG4-related sclerosing disease were documented in patients also diagnosed with PHG, although these reports date from before the description of IgG4 sclerosing disease. This case provides the first definitive evidence that PHG is part of the spectrum of IgG4-related sclerosing disease. PMID:22498827

    Pelvic inflammatory disease (PID) is a common medical problem, with almost 1 million cases diagnosed annually. Historically, PID has been a clinical diagnosis supplemented with the findings from ultrasonography (US) or magnetic resonance (MR) imaging. However, the diagnosis of PID can be challenging because the clinical manifestations may mimic those of other pelvic and abdominal processes. Given the nonspecific clinical manifestations, computed tomography (CT) is commonly the first imaging examination performed. General CT findings of early- and late-stage PID include thickening of the uterosacral ligaments, pelvic fat stranding with obscuration of fascial planes, reactive lymphadenopathy, and pelvic free fluid. Recognition of these findings, as well as those seen with cervicitis, endometritis, acute salpingitis, oophoritis, pyosalpinx, hydrosalpinx, tubo-ovarian abscess, and pyometra, is crucial in allowing prompt and accurate diagnosis. Late complications of PID include tubal damage resulting in infertility and ectopic pregnancy, peritonitis caused by uterine and/or tubo-ovarian abscess rupture, development of peritoneal adhesions resulting in bowel obstruction and/or hydroureteronephrosis, right upper abdominal inflammation (Fitz-Hugh-Curtis syndrome), and septic thrombophlebitis. Recognition of these late manifestations at CT can also aid in proper patient management. At CT, careful assessment of common PID mimics, such as endometriosis, adnexal torsion, ruptured hemorrhagic ovarian cyst, adnexal neoplasms, appendicitis, and diverticulitis, is important to avoid misinterpretation, delay in management, and unnecessary surgery. Correlation with the findings from complementary imaging examinations, such as US and MR imaging, is useful for establishing a definitive diagnosis. (©)RSNA, 2016. PMID:27618331

    Autoimmune pancreatitis (AIP) is a mass-forming chronic fibroinflammatory condition centered on the pancreatobiliary system and characterized by predominant immunoglobulin G4 (IgG4)-positive plasma cells. Recent reports have brought to light the multiorgan involvement of this disease. We describe a series of 5 cases of tubulointerstitial nephritis (TIN) associated with AIP and characterize the clinical, pathologic, ultrastructural, and immunopathologic features of TIN. The specimens consisted of 4 biopsies and 1 nephrectomy. The average patient age was 64 years (range 45 to 78) and the male to female ratio was 4:1. All had histologic and/or clinical and radiographic evidence of AIP, mass-forming sclerosing cholangitis, or both. The clinical impression in 4 patients was a renal mass or vasculitis. Two patients had renal insufficiency. Histologic preparations revealed a dense tubulointerstitial lymphoplasmacytic infiltrate. Eosinophils were often numerous. Tubulitis and tubular injury were present, along with tubular atrophy with focally thickened tubular basement membranes (TBMs). The histologic appearance ranged from a cellular, inflammatory pattern without tubular atrophy to a striking expansive interstitial fibrosis with tubular destruction. The nephrectomy specimen demonstrated a masslike nodular pattern of inflammation with normal renal tissue elsewhere. Glomeruli were uninvolved. By immunohistochemistry or immunofluorescence, numerous plasma cells in the infiltrate were positive for IgG4. TBM granular IgG deposits, predominantly of the IgG4 subclass, were detected in 4 of 5 cases by either immunofluorescence or immunohistochemistry. By electron microscopy, corresponding amorphous electron-dense deposits were present in the TBM in these cases. This type of TIN, typically characterized by a masslike lesion consisting of a lymphoplasmacytic infiltrate with eosinophils and prominent IgG4-positive plasma cells and immune-complex deposits in the TBM, may be part of

    We treated a 61-year-old man with immunoglobulin (Ig)G4-related kidney disease (IgG4-RKD). He had a history of allergic diseases and an allergic reaction and had received a diagnosis of autoimmune pancreatitis (AIP). He had also received a diagnosis of renal cell carcinoma (RCC) and had undergone segmental resection of the left kidney at 59 years of age. His serum amylase level and number of peripheral eosinophils increased after RCC development. We hypothesized that the RCC may have induced AIP and IgG4-RKD and we therefore examined the excised RCC tissue; typical findings of IgG4-RKD associated with RCC were recognized. We next evaluated the mRNA expression of cytokines in the excised tissues of this case and ten other ordinary RCC cases. In all cases, notable levels of IL-10 mRNA and high levels of TGF-β mRNA were seen. Although prominent differences were not observed in the mRNA expression of Th1, Th17 and Treg cytokines in all cases, the present case alone showed increased production of the Th2 cytokines IL-4 and IL-5, which were not detected in ordinary RCC cases. Although the mechanism underlying IgG4-RKD development has not yet been determined, Th2 and Treg cells are thought to play a prominent role in the pathogenesis. It is therefore likely that in this case, the association of these two diseases was not coincidental, and a distinct immune response against RCC may trigger IgG4-RKD development.

    Autoimmune pancreatitis (AIP) is a mass forming inflammatory pancreatobiliary-centric disease. Recent reports of multiorgan inflammatory mass forming lesions with increased numbers of IgG4 positive plasma cells suggest that AIP may have a systemic component. In this study, we explore the systemic nature of AIP, investigate the relevance of subtyping AIP, perform a systematic study of tissue IgG4 immunoperoxidase, and ultrastructurally evaluate the presence of immune complexes. Our study group consisted of 36 patients with AIP, 21 of whom underwent a Whipple procedure. On the basis of the pattern of inflammation, pancreatic involvement was subtyped as ductocentric (AIP-D) or lobulocentric (AIP-L). Extrapancreatic lesions included bile duct (n=3), salivary glands (n=3), lung (n=2), gallbladder (n=11), and kidney (n=4). Clinical and radiologic data was recorded. Immunohistochemistry for IgG4 was performed on both pancreatic and extrapancreatic tissues and the numbers of IgG4 positive plasma cells were semiquantitatively scored. A control cohort composed of pancreatic adenocarcinoma (n=19) and chronic pancreatitis-not otherwise specified (NOS) (n=14) was also evaluated. Eleven pancreatic specimens, including 2 cases of chronic pancreatitis-NOS and 4 kidneys were evaluated ultrastructurally. The pancreas, bile duct, gall bladder, salivary gland, kidney, and lung lesions were characterized by dense lymphoplasmacytic infiltrates with reactive fibroblasts and venulitis. IgG4 positive plasma cells were identified in all pancreatic and extrapancreatic lesions. The AIP cases showed significantly more pancreatic IgG4 positive plasma cells than chronic pancreatitis-NOS or adenocarcinoma (P=0.001). However, IgG4 positive cells were identified in 57.1% of chronic pancreatitis-NOS and 47.4% of ductal adenocarcinoma. Fifteen of 21 resected cases were classified as AIP-D, and 6 as AIP-L, the latter notably showing significantly more IgG4 positive plasma cells than the former (P=0

    Ophthalmic Plastic and Reconstructive Surgery is a specialized area of ophthalmology that deals with the management of deformities and abnormalities of the eyelids, lacrimal system and the orbit. An ophthalmoplastic surgeon is able to identify and correct abnormalities of the ocular adnexae such as ectropion, lid retraction, conjunctival scarring with severe entropion, that can cause secondary ocular surface disorders; manage patients with watering eye, and when needed intervene with a dacryocystorhinostomy by external or endonasal approach and moreover minimize disfigurement following enucleation or evisceration and prevent further corneal damage, alleviate complains of tearing and grittiness, but also cosmetic complaints in patients with Graves’ orbitopathy. Aim of this manuscript was to review current established and recently evolving surgical procedures. PMID:26504698

    The purpose of this report is to describe the case of a 35-year-old patient admitted to the National Oncology Institute in Rabat, Morocco for pelvic pain and deteriorating general status ongoing for 8 months. Clinical and ultrasonographic examination showed a heterogenous mass measuring 7 cm in maximum width located inferior and lateral to the inferior aspect of the right side of the uterus. These findings were suggestive of a malignant tumor of the right ovary. Ovariectomy and omentectomy were performed. Histological examination of surgical specimens demonstrated right tubo-ovarian actinomycosis associated with peritonitis. Genital tract actinomycosis is an uncommon finding in women of childbearing age. It is due to colonization by a pyogenic bacteria (Actinomyces) usually secondary to a gastrointestinal infection, e.g. ileocecum, and sometimes in association with the presence of an intrauterine device or foreign body. Based on this case report, the authors discuss abdominopelvic actinomyocosis with emphasis on tumor-like findings that can lead to misdiagnosis by clinicians and radiologists. PMID:12038184

    The aim of the study was to test the hypothesis that oral plasma cell granuloma may represent a mucosal manifestation of immunoglobulin (Ig)G4-related disease (IgG4-RD) in the oral cavity. The study sample comprised two males and four females, aged 54-79 years (median 62 years). The lesions were localized on gingival/alveolar mucosa (four cases), hard palate, and floor of the mouth, measuring 17-40 mm (median 31 mm). The duration of the lesions ranged from 3 months to several years. Information on IgG4 serum levels was available for two patients, and these were increased to 1.85 and 1.65 g/L, respectively. The follow-up period ranged 11-30 months (median 13 months). None of the lesions recurred, and none of the patients developed any manifestation of IgG4-RD. Microscopically, all cases presented as nodular lesions composed of numerous polyclonal plasma cells admixed with lymphocytes, histiocytes, mast cells, and eosinophils, set within collagenized stroma in variable proportions. Obliterative phlebitis was observed in two cases. The number of IgG4-positive plasma cells ranged between 51 and 142 per HPF (median 114), while the IgG4/IgG ratio values ranged between 0.16 and 0.72 (median 0.44) and were above 0.40 in three cases. Based on international criteria, two cases were diagnosed as definite and one as probable IgG4-RD. Oral plasma cell granuloma is a heterogeneous group of lesions, and a subset may represent a mucosal manifestation of IgG4-RD in the oral cavity. PMID:25522952

    IgG4-related disease is a new disease entity involving IgG4 in its clinical presentation and having 6 characteristic features: (1) systemic involvement; (2) solitary or multiple lesions showing diffuse or localized swelling, masses, nodules, and/or wall thickening on imaging; (3) high serum IgG4 concentration >135 mg/dL; (4) abundant infiltration of lymphoplasmacytes and IgG4-bearing plasma cells; (5) a positive response to corticosteroid therapy; and (6) complications of other IgG4-related diseases. To date, most IgG4-related diseases have been recognized as extrapancreatic lesions of autoimmune pancreatitis. This paper will discuss the utility of IgG4 as a biomarker of IgG4-related diseases, including in the diagnosis of autoimmune pancreatitis and its differentiation from pancreatic cancer, in the prediction of relapse, in the long-term follow-up of patients with autoimmune pancreatitis and normal or elevated IgG4 concentrations, and in patients with autoimmune pancreatitis and extrapancreatic lesions, as well as the role of IgG4 in the pathogenesis of IgG4-related disease.

    Orbital sclerosing inflammation is a distinct group of pathologies characterized by indolent growth with minimal or no signs of inflammation. However, contrary to earlier classifications, it should not be considered a chronic stage of acute inflammation. Although rare, orbital IgG4-related disease has been associated with systemic sclerosing pseudotumor-like lesions. Possible mechanisms include autoimmune and IgG4 related defective clonal proliferation. Currently, there is no specific treatment protocol for IgG4-related disease although the response to low dose steroid provides a good response as compared to non-IgG4 sclerosing pseudotumor. Specific sclerosing inflammations (e.g. Wegener's disease, sarcoidosis, Sjogren's syndrome) and neoplasms (lymphoma, metastatic breast carcinoma) should be ruled out before considering idiopathic sclerosing inflammation as a diagnosis.

    2013-03-01

    The active inflammatory phase of thyroid eye disease (TED) is mediated by the innate immune system, and management is aimed at aborting this self-limited period of autoimmune activity. In most patients with TED, ocular and adnexal changes are mild and management involves controlling thyroid dysfunction, cessation of smoking, and addressing ocular surface inflammation and exposure. In patients with acute moderate disease, this being sufficient to impair orbital functions, immunosuppression reduces the long-term sequelae of acute inflammation, and adjunctive fractionated low-dose orbital radiotherapy is used as a steroid-sparing measure. Elective surgery is often required following moderate TED, be it for proptosis, diplopia, lid retraction, or to debulk the eyelid, and this should be delayed until the disease is quiescent, with the patient stable and weaned off all immunosuppression. Thus, surgical intervention during the active phase of moderate disease is rarely indicated, although clinical experience suggests that, where there is significant orbital congestion, early orbital decompression can limit progression to more severe disease. Acute severe TED poses a major risk of irreversible loss of vision due to marked exposure keratopathy, 'hydraulic' orbital congestion, or compressive optic neuropathy. If performed promptly, retractor recession with or without a suture tarsorrhaphy protects the ocular surface from severe exposure and, in patients not responding to high-dose corticosteroid treatment, decompression of the deep medial orbital wall and floor can rapidly relieve compressive optic neuropathy, as well as alleviate the inflammatory and congestive features of raised orbital pressure.

    The nodular lymphoid lesion of the liver known as reactive lymphoid hyperplasia or pseudolymphoma is rare and its pathogenesis is unknown. We report two cases of nodular lymphoid lesions of the liver with numerous IgG4-positive plasma cells in patients with primary biliary cirrhosis. Histologically, in both cases, the lesion showed a dense lymphoplasmacytic infiltrate with lymphoid follicles and granulomas. Fibrous tissue was scarce and without a storiform pattern. Obliterative phlebitis was not identified. The IgG4+ plasma cell counts were 82 and 76 per high power field, with an IgG4/IgG ratio of 75 and 64 %, respectively, which qualifies the lesions according to the diagnostic criteria for IgG4-related disease as « probable histological feature of IgG4-related disease ». There were no rearrangements of immunoglobulin heavy-chain genes and plasma cells had a polytypic pattern of kappa and lambda light-chain expression. The non-tumor liver showed primary biliary cirrhosis with destructive cholangitis without IgG4 plasma cells. In both cases, IgG4-related disease was not found in other organs neither at the time of diagnosis nor 3 years later. Serum IgG4 levels normalized after local ablation of the lesions. It seems unlikely that these lesions are a manifestation of IgG4-related disease. However, because the pathogenesis of both nodular lymphoid lesions and IgG4-related disease remains unclear, further studies are needed to elucidate a potential link between nodular lymphoid lesions of the liver and an increased number of IgG4 plasma cells. More definite conclusions will be possible when the pathogenesis of IgG4-related disease has been clarified.

    The pathogenesis of granuloma faciale (GF), framed in the group of cutaneous vasculopathic dermatitis, is poorly understood. The present study investigated whether GF might be part of the spectrum of IgG4-related sclerosing diseases (IgG4-RD). Erythema elevatum diutinum (EED), believed to belong to the same group of disorders as GF, was also studied for comparison. Thirty-one biopsies of GF obtained from 25 patients (18 men, 7 women) and 5 cases of EED (4 women and 1 man) were analyzed morphologically and for the expression of IgG and IgG4 by immunohistochemistry. The distribution of Th1, T regulatory and Th2 T-cell subsets, respectively, identified by anti-T-bet, anti-FoxP3, and anti-GATA-3 antibodies, was also evaluated. The dermal inflammatory infiltrate in GF contained eosinophils and plasma cells in variable proportions. Obliterative venulitis was found in 16 cases, and storiform fibrosis, a typical feature of IgG4-RD, was observed in 8 cases and was prominent in 3 of them. On immunohistochemical analysis 7 of 31 biopsies (22.6%) from 6 GF patients fulfilled the criteria for IgG4-RD (IgG4/IgG ratio >40%, and absolute number of IgG4 per high-power field >50). Interestingly, the 6 patients were male, and 4 showed recurrent and/or multiple lesions. In an additional 5 cases, only the IgG4/IgG ratio was abnormal. None of the 5 EED cases fulfilled the criteria for IgG4-RD. The T-cell subsets in GF were quite variable in number, GATA-3 lymphocytes were generally more abundant, but no relationship with the number of IgG4 plasma cells was found. The study indicates that a significant number of GF cases are associated with an abnormal content of IgG4 plasma cells; this association was particularly obvious in male patients and in cases presenting with multiple or recurrent lesions. As morphologic changes typically found in IgG4-RD, such as obliterative vascular inflammation and storiform sclerosis, are found in GF, we suggest that GF might represent a localized form of

  15. Acute Pelvic Inflammatory Disease in Cameroon: A Cross Sectional Descriptive Study.

    This cross-sectional descriptive study, aimed at identifying the sociodemographic characteristics of women diagnosed with acute pelvic inflammatory disease (PID), as well as the microorganisms isolated, was carried out between October 1st, 2013 and March 31st, 2014 in two major hospitals in Yaoundé, Cameroon. Seventy women diagnosed with acute PID were recruited. The main variables recorded were maternal age, occupation, marital status, number of current sexual partners, the clinical presentation at admission and the microorganisms identified. Data were analyzed using SPSS 20.0. Mean maternal age was 29.0 ± 7.7 years. Students were more represented (37.1%), 58.6 % were single, 64.3% had ≥ 2 sexual partners. The most frequent signs and symptoms were abnormal vaginal discharge (100%), adnexal tenderness (97.1%), cervical motion tenderness (94.3%) and fever ≥ 38.3 degrees C (82.9%). No microorganism was isolated in 20% of cases, especially among women who underwent intra-uterine procedures. The most frequent microorganisms were genital tract mycoplasmas (54.3%). Acute PID is common among young, single women with multiple sexual partners. The micro-organisms frequently responsible for acute PID were genital tract mycoplasmas, whose identification should be included among routine tests for women with suspected acute PID in the hospitals.

    OBJECTIVE: To evaluate the clinical diagnosis of pelvic inflammatory disease (PID) compared with the diagnosis of PID made by laparoscopy, endometrial biopsy, transvaginal ultrasound, and cervical and endometrial cultures. Study design: A diagnostic performance test study was carried out by cross-sectional analysis in 61 women. A group presenting PID (n = 31) was compared with a group (n = 30) presenting another cause for non-specific lower abdominal pain (NSLAP). Diagnosis provided by an evaluated method was compared with a standard diagnosis (by surgical findings, histopathology, and microbiology). The pathologist was unaware of the visual findings and presumptive diagnoses given by other methods. RESULTS: All clinical and laboratory PID criteria showed low discrimination capacity. Adnexal tenderness showed the greatest sensitivity. Clinical diagnosis had 87% sensitivity, while laparoscopy had 81% sensitivity and 100% specificity; transvaginal ultrasound had 30% sensitivity and 67% specificity; and endometrial culture had 83% sensitivity and 26% specificity. CONCLUSIONS: Clinical criteria represent the best diagnostic method for discriminating PID. Laparoscopy showed the best specificity and is thus useful in those cases having an atypical clinical course for discarding abdominal pain when caused by another factor. The other diagnostic methods might have limited use. PMID:12648310

    Toxic epidermal necrolysis (TEN) is a severe cutaneous adverse drug reaction leading to extensive sloughing of the skin. Late cutaneous complications such as pigmentation disorders are frequently reported. In this report, we present particular facial cutaneous sequelae with histological analysis after TEN. Two young patients who had survived TEN presented permanent multiple hypopigmented papules on the face affecting their quality of life. Histological analysis revealed areas of scarring, dystrophic microcalcifications and sebaceous hyperplasia. Late cutaneous sequelae are well documented; however, the physiopathological mechanisms leading to different clinical presentations remain unknown. We suggest that the destruction of the hair follicle by necrolysis leads to secondary dermal microcalcifications, scarring and sebaceous hyperplasia. Further studies are needed for a better understanding of these findings. PMID:26866828

    Paavonen, J

    1996-01-01

    The most significant complication of sexually transmitted diseases (STDs) in women is pelvic inflammatory disease (PID), which is responsible for considerable medical, social, and economic problems. Chlamydia trachomatis, Neisseria gonorrhoeae, or both cause PID in at least 50% of cases. Other microorganisms that are part of the abnormal vaginal flora also cause PID. Gonorrhea rates have quickly fallen in most developed countries, but chlamydia infection rates are still high in developed countries as well as in developing countries. The clinical signs and symptoms of PID have changed over time. More and more PID cases are classified as atypical or subclinical. Typical PID is rare. A strong association exists between chlamydia infection and tubal factor infertility or ectopic pregnancy in women with or without a history of PID. Health providers are concerned about the problem of unrecognized PID. Thus, recommendations for PID diagnosis have changed. A syndromic diagnosis of PID is advocated. The minimum criteria for syndromic diagnosis of PID include lower abdominal tenderness, bilateral adnexal tenderness, cervical motion tenderness, and no evidence of competing diagnosis (e.g., acute appendicitis). Application of this improved approach will provide appropriate treatment earlier in the course of PID. PID-related morbidity (i.e., infertility and ectopic pregnancy) is a considerable public health problem worldwide. In order to prevent PID, clinicians and public health specialists need to understand the interactions of PID-causing microorganisms with the host immune system. By the time PID symptoms are detected, considerable tubal damage already exists limiting the effect of tertiary prevention of PID. Secondary prevention keeps lower genital tract infection from moving up to the upper genital tract. Health providers play a key role in secondary prevention by screening for STDs and in primary prevention by counseling patients about safer sex practices.

    1992-04-01

    In September 1991, the 7th IUVDT Regional Conference on Sexually Transmitted Diseases (STDs) convened in Kuala Lumpur, Malaysia, to exchange information on the importance of controlling STDs and HIV-AIDS in Asia. Speakers from Thailand, Malaysia, and Japan provided the latest HIV-AIDS epidemiological data. In Thailand, heterosexual transmission of HIV is catching up with iv drug use. Most infected women are 15-24 years old. In Malaysia, drug use iv drug use trails heterosexual transmission of HIV. In Japan, hemophiliacs comprise 85% of HIV-positive people. Current problems do not compare to the sizable task Asian countries face in affecting the progression of the HIV-AIDS epidemic. All countries need to implement control measures quickly and at the same time. They should not pretend traditional values and beliefs would shield their people from the epidemic. Asian countries should especially stop promoting themselves as places of sexual adventure. Control programs should also target STDs. Australian presenters discussed the results of the Sydney Sexual Lifestyle Study and a study on the effect of zidovudine therapy on the prognosis of AIDS. Another presentation focused on the possibility of a vaccine for chlamydia infection. Several papers centered on the treatment of chancroid and gonococcal and nongonococcal urethritis and evaluation of a detection test for chlamydia infection. 1 participant reviewed the role of human papilloma virus in cervical carcinogenesis. Another participant demonstrated a link between bacterial vaginosis and adnexal tenderness and pelvic infection. The conference concluded with a presenter challenging everyone to meet the HIV-AIDS challenge. Reasons why current control measures do not work include inadequate facilities to manage STDs, tendency not to consider HIV another STD, failure to promote and lack of condoms, and not educating school children about HIV-AIDS.

  13. Prion Diseases

    Geschwind, Michael D.

    2016-01-01

    Purpose of Review This article presents an update on the clinical aspects of human prion disease, including the wide spectrum of their presentations. Recent Findings Prion diseases, a group of disorders caused by abnormally shaped proteins called prions, occur in sporadic (Jakob-Creutzfeldt disease), genetic (genetic Jakob-Creutzfeldt disease, Gerstmann-Sträussler-Scheinker syndrome, and fatal familial insomnia), and acquired (kuru, variant Jakob-Creutzfeldt disease, and iatrogenic Jakob-Creutzfeldt disease) forms. This article presents updated information on the clinical features and diagnostic methods for human prion diseases. New antemortem potential diagnostic tests based on amplifying prions in order to detect them are showing very high specificity. Understanding of the diversity of possible presentations of human prion diseases continues to evolve, with some genetic forms progressing slowly over decades, beginning with dysautonomia and neuropathy and progressing to a frontal-executive dementia with pathology of combined prionopathy and tauopathy. Unfortunately, to date, all human prion disease clinical trials have failed to show survival benefit. A very rare polymorphism in the prion protein gene recently has been identified that appears to protect against prion disease; this finding, in addition to providing greater understanding of the prionlike mechanisms of neurodegenerative disorders, might lead to potential treatments. Summary Sporadic Jakob-Creutzfeldt disease is the most common form of human prion disease. Genetic prion diseases, resulting from mutations in the prion-related protein gene (PRNP), are classified based on the mutation, clinical phenotype, and neuropathologic features and can be difficult to diagnose because of their varied presentations. Perhaps most relevant to this Continuum issue on neuroinfectious diseases, acquired prion diseases are caused by accidental transmission to humans, but fortunately, they are the least common form and

    PubMed

    Vaden, Shelly L

    2011-08-01

    Glomerular diseases are a leading cause of chronic kidney disease in dogs but seem to be less common in cats. Glomerular diseases are diverse, and a renal biopsy is needed to determine the specific glomerular disease that is present in any animal. Familial glomerulopathies occur in many breeds of dogs. However, most dogs with glomerular disease have acquired glomerular injury that is either immune-complex mediated or due to systemic factors, both of which are believed to be the result of a disease process elsewhere in the body (i.e., neoplastic, infectious, and noninfectious inflammatory disorders). A thorough clinical evaluation is indicated in all dogs suspected of having glomerular disease and should include an extensive evaluation for potential predisposing disorders. Nonspecific management of dogs with glomerular disease can be divided into 3 major categories: (1) treatment of potential predisposing disorders, (2) management of proteinuria, and (3) management of uremia and other complications of glomerular disease and chronic kidney disease. Specific management of specific glomerular diseases has not been fully studied in dogs. However, it may be reasonable to consider immunosuppressive therapy in dogs that have developed a form of glomerulonephritis secondary to a steroid-responsive disease (e.g., systemic lupus erythematosus) or have immune-mediated lesions that have been documented in renal biopsy specimens. Appropriate patient monitoring during therapy is important for maximizing patient care. The prognosis for dogs and cats with glomerular disease is variable and probably dependent on a combination of factors. The purpose of this article is to discuss the general diagnosis and management of dogs with glomerular disease. PMID:21782143

    In general, the development of civilization is viewed as a positive step for the well-being of the human species, leading to an increased duration and quality of life. The accelerated progress of civilization (mainly industrialization, urbanization and nutrition) has lead to new possibilities for adverse effects on human health. In former high civilization--like old Egypt, Greece, Roman, Chinese, Indian, Maya civilizations--the "modem civilization diseases" were unknown. Modem science through improved sanitation, vaccination and antibiotics as well as improved social and economical conditions, has eliminated the threat of death from most infectious diseases. In the years after World War II the social, economic and health conditions changed. Most deaths have resulted from heart disease, stroke, cancer and other diseases as a result of an inappropriate relationship of people with their environment and changed lifestyle. Lifestyle diseases are different from other diseases because they are potentially preventable and can be lowered with changes in diet, lifestyle and environment. PMID:18350729

    Gaucher disease is the commonest lysosomal storage disease seen in India and worldwide. It should be considered in any child or adult with an unexplained splenohepatomegaly and cytopenia which are seen in the three types of Gaucher disease. Type 1 is the non-neuronopathic form and type 2 and 3 are the neuronopathic forms. Type 2 is a more severe neuronopathic form leading to mortality by 2 years of age. Definitive diagnosis is made by a blood test-the glucocerebrosidase assay. There is no role for histological examination of the bone marrow, liver or spleen for diagnosis of the disease. Molecular studies for mutations are useful for confirming diagnosis, screening family members and prognosticating the disease. A splenectomy should not be performed except for palliation or when there is no response to enzyme replacement treatment or no possibility of getting any definitive treatment. Splenectomy may worsen skeletal and lung manifestations in Gaucher disease. Enzyme replacement therapy (ERT) has completely revolutionized the prognosis and is now the standard of care for patients with this disease. Best results are seen in type 1 disease with good resolution of splenohepatomegaly, cytopenia and bone symptoms. Neurological symptoms in type 3 disease need supportive care. ERT is of no benefit in type 2 disease. Monitoring of patients on ERT involves evaluation of growth, blood counts, liver and spleen size and biomarkers such as chitotriosidase which reflect the disease burden. Therapy with ERT is very expensive and though patients in India have so far got the drug through a charitable access programme, there is a need for the government to facilitate access to treatment for this potentially curable disease. Bone marrow transplantation is an inferior option but may be considered when access to expensive ERT is not possible. PMID:25755533

    Finkbeiner, Steven

    2011-01-01

    Huntington's disease (HD) is the most common inherited neurodegenerative disease and is characterized by uncontrolled excessive motor movements and cognitive and emotional deficits. The mutation responsible for HD leads to an abnormally long polyglutamine (polyQ) expansion in the huntingtin (Htt) protein, which confers one or more toxic functions to mutant Htt leading to neurodegeneration.

    Wilson's disease is a disorder of the liver's copper metabolism. Accumulation of copper causes liver and central nervous system damage. Wilson's disease should always be suspected, when a liver disease is detected in a child or an adolescent. The disease may also manifest itself as severe neurological or neuropsychiatric disorders. The diagnosis is often delayed despite the fact that the accumulation of copper in the body can be shown by various means. Early started medication will stop the accumulation of copper into the body. If the treatment is delayed or ineffective, liver transplantation is required.

    The representatives of immunoinflammatory diseases are rheumatic ones, such as primarily rheumatoid arthritis, juvenile idiopathic arthritis, spondyloarthritis, psoriatic arthritis, systemic lupus erythematosus, and other systemic connective diseases, which are characterized by a high risk for untimely death. The high risk of untimely death in these diseases has been found to be associated with the severity of an immunoinflammatory process that gives rise to severe irreversible damage to vital organs and systems and with the development of a wide spectrum of comorbidities (infections, interstitial lung disease, malignant tumors, osteoporotic fractures, etc.). Among them, diseases of the cardiovascular system, which are most commonly caused by the early development and.accelerated progression of atherosclerotic coronary lesions, hold a central.position. The paper gives the data available in the recent literature on the impact.of antirheumatic therapy (disease-modifying antirheumatic drugs and biological agents) on' the cardiovascular system.

    Paget's disease of bone is the most common metabolic bone disease after osteoporosis and affects 2-4% of adults over 55 years of age. Its etiology is only partly understood and includes both genetic and environmental factors. The disease may be asymptomatic and can be uncovered incidentally on x-ray or in biochemical tests performed for another condition. It can also manifest itself with bone pain, deformity, fracture or other complications. Paget's disease is diagnosed by x-rays and in general has very typical radiological features, but occasionally the clinical picture may be unusual and a differential diagnosis of sclerotic or lytic metastases needs to be considered. Plasma total alkaline phosphatase activity is the most clinically useful indicator of disease activity. It is elevated in most untreated patients, but may be within the normal range in patients with monostotic or limited disease. Bisphosphonate therapy is indicated for patients with symptoms and should also be considered in patients with disease sites that suggest a risk of complications, such as long bones, vertebrae or base of the skull. Orthopedic surgery in Paget's disease patients includes almost exclusively the correction of fractures and arthroplasty. PMID:25069498

    We aim to describe an 8-year-old boy with an unusual clinical presentation of Gaucher disease (GD). Gaucher disease is a progressive lysosomal storage disorder due to deficiency of the specific enzyme glucocerebrosidase with varying clinical features, but often involving the monocytes-macrophages systems. This child ran a progressive course with a devastating outcome. Three distinct GD subtypes have been described with varying clinical features based on the presence or absence of neurologic involvement. Gaucher disease diagnosis is obtained via: enzyme activity assay, gene mutation study, bone marrow aspiration in addition to multiple other tests that have been successfully used in diagnosis of cases of GD. Treatment modalities include enzyme replacement treatment, substrate reduction therapy, bone marrow transplantation, blood transfusion, and surgery are available management modalities for GD. Gaucher disease is a chronic disease requiring a multidisciplinary team approach with regular follow up with multiple subspecialties. PMID:26166597

    The increasing use of beryllium in a variety of industries continues to be a hazard. New cases are still being reported to the UK Beryllium Case Registry, now numbering 60 in the period 1945-1988. The majority of cases follow inhalation which results in acute beryllium disease (chemical pneumonitis) or more commonly chronic beryllium disease--a granulomatous pneumonitis. Granulomatous skin nodules also occur following local implantation. The clinical and radiological features are briefly described with the emphasis on pathology and immunology. Laser microprobe mass spectrometry analysis of tissue sections is a major advance in diagnosis. Detection of beryllium distinguishes the granulomas of chronic beryllium disease from other diseases, in particular sarcoidosis. The role of beryllium lymphocyte transformation tests is discussed. Chronic beryllium disease is steroid dependent and local excision of skin lesions appears to be curative. There is no evidence that beryllium is carcinogenic. Images Figure 1 PMID:3074283

    Although the prevalence of dementia continues to increase worldwide, incidence in the western world might have decreased as a result of better vascular care and improved brain health. Alzheimer's disease, the most prevalent cause of dementia, is still defined by the combined presence of amyloid and tau, but researchers are gradually moving away from the simple assumption of linear causality as proposed in the original amyloid hypothesis. Age-related, protective, and disease-promoting factors probably interact with the core mechanisms of the disease. Amyloid β42, and tau proteins are established core cerebrospinal biomarkers; novel candidate biomarkers include amyloid β oligomers and synaptic markers. MRI and fluorodeoxyglucose PET are established imaging techniques for diagnosis of Alzheimer's disease. Amyloid PET is gaining traction in the clinical arena, but validity and cost-effectiveness remain to be established. Tau PET might offer new insights and be of great help in differential diagnosis and selection of patients for trials. In the search for understanding the disease mechanism and keys to treatment, research is moving increasingly into the earliest phase of disease. Preclinical Alzheimer's disease is defined as biomarker evidence of Alzheimer's pathological changes in cognitively healthy individuals. Patients with subjective cognitive decline have been identified as a useful population in whom to look for preclinical Alzheimer's disease. Moderately positive results for interventions targeting several lifestyle factors in non-demented elderly patients and moderately positive interim results for lowering amyloid in pre-dementia Alzheimer's disease suggest that, ultimately, there will be a future in which specific anti-Alzheimer's therapy will be combined with lifestyle interventions targeting general brain health to jointly combat the disease.

    Lyme disease (Borreliosis), also called the "disease of 1000 faces", is produced by a bacterium called Borrelia burgdorferi, transmitted by the Ixodes tick. The clinical picture is non-specific and polymorph, with multisystemic involvement. Diagnosis is most often one of exclusion, and certain diagnosis is based on the presence of Borellia antibodies. The treatment is done differently depending on the stage of the disease and the severity of injuries, being used antibiotics like Doxycycline, Amoxicillin, Erythromycin or Penicillin. Under treatment the disease quickly heals without sequel, in the early stages, but advanced stages are usually resistant to treatment and chronic injuries can occur. Symptoms get worse without treatment and become chronic. We present the case of a woman of 66-year-old with a complex history of disease, which began one year prior to admission, through multiple and nonspecific symptoms; she presented herself in numerous medical services (gastroenterology, rheumatology--where an immunosuppressive treatment was initiated, hematology) without determining a final diagnosis. She was admitted in our service with altered general state and worsening symptoms, predominantly fever, muscle pain, joint pain, the patient being immobilized in bed. After multiple investigations and the problem of differential diagnosis with multiple pathologies, we finally established the diagnosis of Lyme disease. The peculiarities of the case are represented by the severity of the clinical manifestations and fulminant disease evolution under the unjustified administration of immunosuppressive treatment, and atypical joint involvement regarding localization and evolution that raised the issue of differential diagnosis with osteosarcoma or bone tuberculosis.

    Parkinson's disease is a common disabling disease of old age. The diagnosis of idiopathic Parkinson's disease is based on clinical signs and has poor sensitivity, with about 25% of patients confidently diagnosed as having the disease actually having other conditions such as multi-system atrophy and other parkinsonism-plus syndromes. Benign essential tremor and arteriosclerotic pseudo-parkinsonism can easily be confused with Parkinson's disease. The cause of Parkinson's disease remains unknown. Speculative research highlights the role of oxidative stress and free radical mediated damage to dopaminergic cells. Parkinson's disease is the one neurodegenerative disorder in which drugs have been demonstrated to be of value. There is now a wide variety of drugs and formulations available, including anticholinergics, amantidine, L-dopa, dopamine agonists including apomorphine, selegiline and soon to be available catechol-O-methyltransferase inhibitors. Disabling side-effects of treatment, fluctuations, dyskinesias and psychiatric problems require strategic use of the drugs available. There is an increasing potential for neurosurgical intervention.

    Castleman disease or angiofollicular hyperplasia is a rare disorder included in the group of lymphoproliferative disorders. This entity was originally described by Castleman in 1956. The etiology remains unknown but it is postulated to be a reactive lymphoid hyperplasia due to chronic antigenic stimulation caused by a viral infection. The disease presents in young adults and is more frequent in women; it is exceptionally rare in the pediatric age group. It is classified into two clinical groups (localized disease and disseminated disease) and there are two histologic variants (hyaline-vascular and plasma cell Castleman disease). Localized disease is usually asymptomatic, has a good prognosis, and is the most common presentation in pediatric patients, usually corresponding to highly vascularized mediastinal masses. Resection of the mass, which is curative, is associated with a high risk of blood loss. Recently, preoperative arteriography with embolization has been used satisfactorily in the preoperative management of these tumors. We present a case of localized Castleman disease in a 12-year-old girl satisfactorily treated with embolization before curative resection.

    Gaucher's disease (GD) is the most common amongst the various disorders classified under the lysosomal storage disorders. GD is a model for applications of molecular medicine to clinical delineation, diagnosis, and treatment. The multiorgan and varied presentation of the disease makes it a challenge to diagnose GD early. The advent of enzyme replacement therapy in the early 1990s changed the management, and survival, of patients with GD. In addition to this, development of substrate reduction, pharmacological chaperone, and gene therapies has broadened the horizon for this rare disease. However, in resource-poor countries like ours, optimal management is still a distant dream. PMID:21897894

    Crohn disease (CD) is a chronic and debilitating inflammatory condition of the gastrointestinal tract.1 Prevalence in western populations is 100–150/100,000 and somewhat higher in Ashkenazi Jews. Peak incidence is in early adult life, although any age can be affected and a majority of affected individuals progress to relapsing and chronic disease. Medical treatments rely significantly on empirical corticosteroid therapy and immunosuppression, and intestinal resectional surgery is frequently required. Thus, 80% of patients with CD come to surgery for refractory disease or complications. It is hoped that an improved understanding of pathogenic mechanisms, for example by studying the genetic basis of CD and other forms of inflammatory bowel diseases (IBD), will lead to improved therapies and possibly preventative strategies in individuals identified as being at risk.

    Kawasaki disease (KD), first described in Japan in 1967 by Dr. Tomisaku Kawasaki, is an acute multi system vasculitis of infancy and early childhood characterised by high fever, rash, conjunctivitis, inflammation of the mucous membranes, erythematous induration of the hands and feet and cervical lymphadenopathy. Synonyms for Kawasaki disease include "Kawasaki syndrome" and "mucocutaneous lymph node syndrome" (MCLS, MLNS, MCLNS). Kawasaki disease was initially presumed to occur only in Japan; but now this disease is known in the whole world. The first cases in the United States were reported in Hawaii in 1976. In poland 5 cases were recognized, and first time described in 1981. The etiology of Kawasaki disease remains unknown. Toxic, allergic and immunologic causes have been suspected, but most investigators favor an infectious cause or an immune response to an infectious agent. Among classes of microorganism suspected of causing Kawasaki disease were bacteria, leptospires, fungi, rickettsiae and a number of viruses. Recently, there has been considerable interest in the possibility, that Kawasaki disease is caused by RETROVIRUSES. Although the disease is generally benign and self-limited, about 20% of children develop coronary artery aneurysms. In 5% of cases, giant aneurysm/more then 8 mm/develop, predisposing the patient to acute coronary artery thrombosis, myocardial infarction and sudden death. This is the most serious complication of KD. Other manifestations of hearth involvement, include pericarditis, myocarditis, myocardial failure and mitral regurgitation. Besides this many other clinical findings are commonly noted in KD; such as: pneumonia, diarrhea, arthritis, aseptic meningitis, otitis media, obstructive jaundice, hydrops of gallbladder and others.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7545822

    Fabry disease, an X-linked disorder of glycosphingolipids that is caused by mutations of the GLA gene that codes for α-galactosidase A, leads to dysfunction of many cell types and includes a systemic vasculopathy. As a result, patients have a markedly increased risk of developing ischemic stroke, small-fiber peripheral neuropathy, cardiac dysfunction and chronic kidney disease. Virtually all complications of Fabry disease are non-specific in nature and clinically indistinguishable from similar abnormalities that occur in the context of more common disorders in the general population. Recent studies suggested a much higher incidence of mutations of the GLA gene, suggesting that this disorder is under-diagnosed. However, some of the gene variants may be benign. Although the etiology of Fabry disease has been known for many years, the mechanism by which the accumulating α-D-galactosyl moieties cause this multi organ disorder has only recently been studied and is yet to be completely elucidated. Specific therapy for Fabry disease has been developed in the last few years but its role in the management of the disorder is still being investigated. Fortunately, standard 'non-specific' medical and surgical therapy is effective in slowing deterioration or compensating for organ failure in patients with Fabry disease. PMID:26564084

    Whipple's disease is a systemic bacterial infection and the common though not invariable manifestations are diarrhoea, weight loss, abdominal pain, and arthralgia. Arthritis or arthralgia may be the only presenting symptom, predating other manifestations by years. Virtually all organs in the body may be affected, with protean clinical manifestations. Various immunological abnormalities, some of which may be epiphenomena, are described. The causative organism is Tropheryma whippelii.
The disease is uncommon though lethal if not treated. Recent data suggest the disease occurs in an older age group than previously described. The characteristic histopathological features are found most often in the small intestine. These are variable villous atrophy and distension of the normal villous architecture by an infiltrate of foamy macrophages with a coarsely granular cytoplasm, which stain a brilliant magenta colour with PAS. These pathognomonic PAS positive macrophages may also be present in the peripheral and mesenteric lymph nodes and various other organs. The histological differential diagnoses include histoplasmosis and Mycobacterium avium-intercellulare complex.
The clinical diagnosis of Whipple's disease may be elusive, especially if gastrointestinal symptoms are not present. A unique sign of CNS involvement, if present, is oculofacial-skeletal myorhythmia or oculomasticatory myorhythmia, both diagnostic of Whipple's disease. A small bowel biopsy is often diagnostic, though in about 30% of patients no abnormality is present. In patients with only CNS involvement, a stereotactic brain biopsy can be done under local anaesthetic. A recent important diagnostic test is polymerase chain reaction of the 16S ribosomal RNA of Tropheryma whippelii.
Whipple's disease is potentially fatal but responds dramatically to antibiotic treatment. In this review the current recommended treatments are presented. The response to treatment should be monitored closely, as relapses are

    Behcet's disease (BD) is a systemic disorder of recurrent acute inflammation, characterized by major symptoms of oral aphthous ulcers, uveitis, skin lesions and genital ulcers. Involvement of intestines, vessels, and central nervous system (CNS) sometimes leads to a poor prognosis. Patients with BD are known to distribute along the ancient Silk Road. The incidence is relatively higher from eastern Asia to the Mediterranean area as roughly 1-10 patients in 10,000 people, whereas only 1-2 patients in 1,000,000 people in UK and North America. Although etiology of the disease is still unknown, high prevalence of HLA-B51, increased expression of heat shock protein 60 and Th1 dominant immune responses in the patients are considered important in its pathogenesis. Non-infectious neutrophil activation and infection with Streptococcus sanguis and herpes simplex virus would also be associated. Because BD lacks any pathognomonic symptoms and laboratory findings, the diagnosis relies largely upon the criteria proposed by the International Study Group for Behcet's disease in 1990. In Japan, the diagnosis was also made according to the Japanese criteria revised in 1987. Recently, the Behcet's Disease Research Committee of Japan again revised the Japanese criteria in 2003 to avoid overdiagnosis. The new Japanese criteria are introduced in this review.

    With 16.9 million people who suffered a first-ever stroke in 2010 worldwide, stroke is a very common vascular disease. Epidemiologic studies have played an essential role in assessing this burden and in detecting the risk factors for stroke. Primary prevention of these risk factors, primarily hypertension, smoking, diabetes, and atrial fibrillation, has reduced the incidence in high-income countries. However, stroke remains a major cause of death and disability, and therefore research should be continued. Subarachnoid hemorrhages are less prevalent than strokes but have an even higher risk of death. Similar to stroke, epidemiologic studies identified smoking and hypertension as its most important risk factors, together with excessive alcohol intake. Although rare, arterial dissections, CADASIL, arteriovenous malformations, venous sinus thrombosis, moyamoya disease, and vasculitis can lead to serious symptoms. The burden and risk factors of those rare diseases are more challenging to assess. Whenever possible, they should be recognized in a timely manner for their increased risk of stroke, but most often they are diagnosed only at the time of stroke. Some cerebrovascular abnormalities do not result in immediate symptoms. This subclinical cerebrovascular disease includes silent infarcts, white-matter lesions, and microbleeds, and is incidentally found by neuroimaging. These lesions are not innocent, as several epidemiologic studies have associated subclinical cerebrovascular disease with an increased risk of stroke, cognitive decline, dementia, and death.

    The syndrome of recurrent vitreous hemorrhages in young men was described for the first time by Henry Eales in 1880. The association with a clinical manifestation of ocular inflammation was reported 5years later. Eales disease affects young adults who present with ischemic retinal vasculitis, with the peripheral retina most commonly affected. Most cases have been reported in South Asia. Although the etiology of this abnormality is unknown, it may be related to an immune sensitivity to Mycobacterium tuberculosis antigens. Its pathogenesis is related to extensive ischemia that affects the retina, secondary to an obliterative retinal vasculopathy with release of angiogenic factors of the VEGF type. Involvement of the retina is the hallmark of the disease, which manifests as follows: periphlebitis, retinal capillary ischemia most often affecting the periphery with secondary proliferative retinopathy and retinal and/or papillary neovascularization, recurrent vitreous hemorrhages and tractional retinal detachment. These complications are potentially blinding. The natural history of Eales disease varies, with temporary or permanent remission in some cases and continuous progression in others. Progression is often bilateral, which necessitates regular follow-up. The treatment of Eales disease depends on the stage of the disease and is not well defined. Observation only, pars plana vitrectomy surgery and/or intravitreal injections of anti-VEGF are recommended in cases of vitreous hemorrhage, associated with corticosteroids when retinal vasculitis is present. Laser pan-retinal photocoagulation is necessary when neovascularization is present. PMID:27185661

    Kawasaki disease is an acute, self-limited vasculitis of unknown etiology that occurs predominantly in infants and children. If not treated early with high-dose intravenous immunoglobulin, 1 in 5 children develop coronary artery aneurysms; this risk is reduced 5-fold if intravenous immunoglobulin is administered within 10 days of fever onset. Coronary artery aneurysms evolve dynamically over time, usually reaching a peak dimension by 6 weeks after illness onset. Almost all the morbidity and mortality occur in patients with giant aneurysms. Risk of myocardial infarction from coronary artery thrombosis is greatest in the first 2 years after illness onset. However, stenosis and occlusion progress over years. Indeed, Kawasaki disease is no longer a rare cause of acute coronary syndrome presenting in young adults. Both coronary artery bypass surgery and percutaneous intervention have been used to treat Kawasaki disease patients who develop myocardial ischemia as a consequence of coronary artery aneurysms and stenosis.

    Refsum's disease, firstly described almost 50 years ago by the Norvegian neurologist Sigvald Refsum, is an autosomic recessive disease affecting mostly the Scandinavians and the populations originating from Northern Europe. The disease results from a specific enzyme deficiency of the first step of phytanic acid catabolism pathway. This deficiency leads to an accumulation of this C20 fatty acid in the serum and the tissues with a preference for adipose tissue, liver and kidneys. The clinical picture includes retinitis pigmentosa, peripheral neuropathy, ataxia and elevated cerebrospinal fluid protein concentration. Other less frequent manifestations include cranial nerves deficiency, myocardiopathy, renal tubular dysfunction and ichtyosis. The diagnosis relies on serum phytanic acid measurement. The treatment consists of a phytanic-acid free diet sometimes associated with plasmapheresis. This treatment is generally effective on neuropathy but not on cranial nerves dysfunction and retinitis pigmentosa.

  14. Dent's disease

    PubMed Central

    2010-01-01

    Dent's disease is a renal tubular disorder characterized by manifestations of proximal tubule dysfunction, including low-molecular-weight proteinuria, hypercalciuria, nephrolithiasis, nephrocalcinosis, and progressive renal failure. These features are generally found in males only, and may be present in early childhood, whereas female carriers may show a milder phenotype. Prevalence is unknown; the disorder has been reported in around 250 families to date. Complications such as rickets or osteomalacia may occur. The disease is caused by mutations in either the CLCN5 (Dent disease 1) or OCRL1 (Dent disease 2) genes that are located on chromosome Xp11.22 and Xq25, respectively. CLCN5 encodes the electrogenic Cl-/H+ exchanger ClC-5, which belongs to the CLC family of Cl- channels/transporters. OCRL1 encodes a phosphatidylinositol bisphosphate (PIP2) 5-phosphatase and mutations are also associated with Lowe Syndrome. The phenotype of Dent's disease is explained by the predominant expression of ClC-5 in the proximal tubule segments of the kidney. No genotype-phenotype correlation has been described thus far, and there is considerable intra-familial variability in disease severity. A few patients with Dent's disease do not harbour mutations in CLCN5 and OCRL1, pointing to the involvement of other genes. Diagnosis is based on the presence of all three of the following criteria: low-molecular-weight proteinuria, hypercalciuria and at least one of the following: nephrocalcinosis, kidney stones, hematuria, hypophosphatemia or renal insufficiency. Molecular genetic testing confirms the diagnosis. The differential diagnosis includes other causes of generalized dysfunction of the proximal tubules (renal Fanconi syndrome), hereditary, acquired, or caused by exogenous substances. Antenatal diagnosis and pre-implantation genetic testing is not advised. The care of patients with Dent's disease is supportive, focusing on the treatment of hypercalciuria and the prevention of

    The monogenic autoinflammatory diseases are rare, genetic disorders resulting in constitutive innate immune defects leading to excessive response to danger signals, spontaneous activation of inflammatory mediators or loss of inhibitory regulators. During the past 15 years, a growing number of monogenic inflammatory diseases have been described and their respective responsible genes identified. The proteins encoded by these genes are involved in the regulatory pathways of inflammation and are mostly expressed in cells of the innate immune system. Although a group of patients exhibit episodic systemic inflammation (periodic fevers), these disorders are mediated by continuous overproduction and release of pro-inflammatory mediators, notably IL-1β, and are best considered as autoinflammatory diseases rather than periodic fevers. The most common autoinflammatory diseases are familial Mediterranean fever (FMF), TNF receptor-associated periodic syndrome (TRAPS), mevalonate kinase deficiency/hyperimmunoglobulin D syndrome (MKD/HIDS) and the cryopyrin-associated periodic syndromes (CAPS). Clinical features often include fever, cutaneous rash, serosal involvement and acute phase reactants. Autoantibodies are usually absent but may accompany certain syndromes. Diagnosis remains clinical and is based on the different phenotypic features. Genetic diagnosis is of utmost importance, but must be performed judiciously and interpreted cautiously. Treatment with biologic agents that block proinflammatory cytokines, particularly IL-1, has proved to be dramatically effective in many patients. Still, in many cases of autoinflammation no genetic abnormalities are detected and treatment remains suboptimal, raising the question of novel pathogenic mutations in unexplored genes and pathways.

    Celiac disease, with a prevalence around 1% of the general population, is the most common genetically-induced food intolerance in the world. Triggered by the ingestion of gluten in genetically predisposed individuals, this enteropathy may appear at any age, and is characterized by a wide variety of clinical signs and symptoms. Among them, gastrointestinal presentations include chronic diarrhea, abdominal pain, weight loss or failure to thrive in children; but extra-intestinal manifestations are also common, and actually appear to be on the rise. They include a large variety of ailments, such as dermatitis Herpetiformis, anemia, short stature, osteoporosis, arthritis, neurologic problems, unexplained elevation of transaminases, and even female infertility. For the clinician interested in oral diseases, celiac disease can lead to delayed tooth eruption, dental enamel hypoplasia, recurrent oral aphthae. Diagnosing celiac disease requires therefore a high degree of suspicion followed by a very sensitive screening test: serum levels of the autoantibody anti-tissue transglutaminase. A positive subject will then be confirmed by an intestinal biopsy, and will then be put on a strict gluten-free diet, that in most cases will bring a marked improvement of symptoms. Newer forms of treatment which in the future will probably be available to the non-responsive patients are currently being actively pursued. PMID:23496382

    This review will focus on the pathogenesis, clinical manifestations, diagnosis, and management of celiac disease (CD). Given an increasing awareness of gluten-related disorders, medical professionals of all varieties are encountering patients with a diagnosis of CD or who are thought to have food intolerance to gluten. The prevalence of CD among the general population is estimated to be 1% in Western nations, and there is growing evidence for underdiagnosis of the disease, especially in non-Western nations that were traditionally believed to be unaffected. The development of serologic markers specific to CD has revolutionized the ability both to diagnose and monitor patients with the disease. Additionally, understanding of the clinical presentations of CD has undergone a major shift over the past half century. Although it is well understood that CD develops in genetically predisposed subjects exposed to gluten, the extent of other environmental factors in the pathogenesis of the disease is an area of continued research. Currently, the main therapeutic intervention for CD is a gluten-free diet; however, novel nondietary agents are under active investigation. Future areas of research should also help us understand the relationship of CD to other gluten-related disorders.

    Lyme disease is among the most frequently diagnosed zoonotic tick-borne diseases worldwide. The number of human cases has been on the increase since the first recognition of its aetiological agent. Lyme disease is caused by spirochete bacteria belonging to the genus Borrelia, with B. burgdorferi sensu stricto (s.s.) found in the Americas, and B. afzelii and B. garinii, in addition to B. burgdorferi s.s., in Europe and Asia. Environmental factors, such as human encroachment onto habitats favourable to ticks and their hosts, reduced deforestation, increased human outdoor activities, and climatic factors favouring a wider distribution of tick vectors, have enhanced the impact of the disease on both humans and animals. Clinical manifestations in humans include, in the early phases, erythema migrans, followed several weeks later by neuro-borreliosis (meningo-radiculitis, meningitis or meningo-encephalitis), Lyme arthritis and/or Borrelia lymphocytoma. In dogs, acute signs include fever, general malaise, lameness, lymph node enlargement and polyarthritis, as well as neuro-borreliosis in the chronic form. Diagnosis is mainly serological in both humans and animals, based on either a two-tier approach (an immunoenzymatic test followed by a Western blot confirmatory test) in humans or C(6) peptide, only in dogs. Early treatment with antibiotics, such as doxycycline or amoxicillin, for three weeks usually reduces the risk of chronic disease. Tick control, including the use of tick repellents for both humans and animals, particularly dogs, is highly reliable in preventing transmission. Vaccines are not available to prevent human infection, whereas several vaccines are available to reduce transmission and the clinical manifestations of infection in dogs.

    Fabry disease (FD) is a progressive, X-linked inherited disorder of glycosphingolipid metabolism due to deficient or absent lysosomal α-galactosidase A activity. FD is pan-ethnic and the reported annual incidence of 1 in 100,000 may underestimate the true prevalence of the disease. Classically affected hemizygous males, with no residual α-galactosidase A activity may display all the characteristic neurological (pain), cutaneous (angiokeratoma), renal (proteinuria, kidney failure), cardiovascular (cardiomyopathy, arrhythmia), cochleo-vestibular and cerebrovascular (transient ischemic attacks, strokes) signs of the disease while heterozygous females have symptoms ranging from very mild to severe. Deficient activity of lysosomal α-galactosidase A results in progressive accumulation of globotriaosylceramide within lysosomes, believed to trigger a cascade of cellular events. Demonstration of marked α-galactosidase A deficiency is the definitive method for the diagnosis of hemizygous males. Enzyme analysis may occasionnally help to detect heterozygotes but is often inconclusive due to random X-chromosomal inactivation so that molecular testing (genotyping) of females is mandatory. In childhood, other possible causes of pain such as rheumatoid arthritis and 'growing pains' must be ruled out. In adulthood, multiple sclerosis is sometimes considered. Prenatal diagnosis, available by determination of enzyme activity or DNA testing in chorionic villi or cultured amniotic cells is, for ethical reasons, only considered in male fetuses. Pre-implantation diagnosis is possible. The existence of atypical variants and the availability of a specific therapy singularly complicate genetic counseling. A disease-specific therapeutic option - enzyme replacement therapy using recombinant human α-galactosidase A - has been recently introduced and its long term outcome is currently still being investigated. Conventional management consists of pain relief with analgesic drugs

    Huntington's disease may present at any age, but most typically manifests between the ages of 35 and 45 years as a slowly progressive neurodegenerative movement disorder with cognitive and behavioral impairment. It is an autosomal-dominant disorder that has a substantial impact on family structure and dynamics in terms of providing care for affected family members and, for the offspring of an affected parent, dealing with at-risk status. Therapy that slows the progressive neuronal dysfunction or degeneration is unavailable, so pharmacotherapy is currently aimed primarily at managing behavioral and psychiatric symptoms, and, in selected cases, controlling severe chorea. Effective intervention by clinicians is possible, however, in terms of providing patients and families with accurate information about the disease, counseling them about availability of genetic testing at specialized centers, and in giving them sound advice regarding work, driving, relationships, finances, research participation, and support groups.

    2013-01-01

    Gaucher disease is an autosomal recessive condition due to glucocerebrosidase deficiency responsible for the lysosomal accumulation of glucosylceramide, a complex lipid derived from cell membranes, mainly in macrophages. It is due to mutations mostly in the GBA gene, although saposine C deficiency is due to mutations in the PSAP gene. It encompasses an extremely heterogeneous spectrum of clinical involvement from the fetus to adulthood. Splenomegaly, blood cytopenia, and bone involvement are the main manifestations of Gaucher disease, but nervous system degeneration is observed in about 5-10% of patients. The accumulation in neurons of glucosylceramide and its derivative, psychosine, are thought to underlie neuronal dysfunction and death, although Gaucher cells that mostly accumulate such substances are mainly macrophages. Enzyme replacement therapy dramatically improves the outcome of patients because of its extreme efficacy in the treatment of the systemic involvement. However, it has only limited effects on most neurological signs. PMID:23622393

    Wilsons disease is an autosomal recessive genetic disorder in which copper accumulates in tissues, especially in the liver and the brain. The genetic defect affects the P type ATPase gene (ATP7B). More than 500 mutations causing Wilsons disease have been described. The most common mutation in Central Europe concerns H1069Q. The symptoms of Wilsons disease include hepatic or neurological conditions. The hepatic condition is manifested as steatosis, acute or chronic hepatitis or cirrhosis. The neurological conditions are most often manifested after the age of 20 as motor disorders (tremor, speech and writing disorders), which may result in severe extrapyramidal syndrome with rigidity, dysarthria and muscle contractions. The dia-gnosis is based on clinical and laboratory assessments (neurological signs, liver lesions, low ceruloplasmin, increased free serum copper, high Cu volumes in urine, KayserFleischer ring). The dia-gnosis is confirmed by a high Cu level in liver tissue or genetic proof. Untreated Wilsons disease causes death of the patient. If treated properly the survival rate approximates to the survival rate of the common population. The treatment concerns either removal of copper from the body using chelating agents excreted into the urine (Penicillamine, Trientine) or limitation of copper absorption from the intestine and reducing the toxicity of copper (zinc, ammonium tetrathiomolybdate). In the Czech Republic, Penicillamine or zinc is used. A liver transplant is indicated in patients with fulminant hepatic failure or decompensated liver cirrhosis. In the family all siblings of the affected individual need to be screened in order to treat any asymptomatic subjects.

    After two workers at the nuclear weapons plant at Oak Ridge National Laboratory in Tennessee were diagnosed earlier this year with chronic beryllium disease (CBD), a rare and sometimes fatal scarring of the lungs, the Department of Energy ordered up a 4-year probe. Now, part of that probe has begun - tests conducted by the Oak Ridge Associated Universities' Center for Epidemiological Research measuring beryllium sensitivity in 3,000 people who've been exposed to the metal's dust since Manhattan Project managers opened the Y-12 plant at Oak Ridge in 1943. Currently, 119 Y-12 employees process beryllium, which has a number of industrial uses, including rocket heat shields and nuclear weapon and electrical components. The disease often takes 20 to 25 years to develop, and the stricken employees haven't worked with beryllium for years. There is no cure for CBD, estimated to strike 2% of people exposed to the metal. Anti-inflammatory steroids alleviate such symptoms as a dry cough, weight loss, and fatigue. Like other lung-fibrosis diseases that are linked to lung cancer, some people suspect CBD might cause some lung cancer. While difficult to diagnose, about 900 cases of CBD have been reported since a Beryllium Case Registry was established in 1952. The Department of Energy (DOE) estimates that about 10,000 DOE employees and 800,000 people in private industry have worked with beryllium.

    Loudianos, G; Gitlin, J D

    Wilson's disease is an autosomal recessive disorder of copper metabolism resulting from the absence or dysfunction of a copper transporting P-type ATPase encoded on chromosome 13. This ATPase is expressed in hepatocytes where it is localized to the trans-Golgi network and transports copper into the secretory pathway for incorporation into ceruloplasmin and excretion into the bile. Under physiologic circumstances, biliary excretion represents the sole mechanism for copper excretion, and thus affected individuals have progressive copper accumulation in the liver. When the capacity for hepatic storage is exceeded, cell death ensues with copper release into the plasma, hemolysis, and tissue deposition. Presentation in childhood may include chronic hepatitis, asymptomatic cirrhosis, or acute liver failure. In young adults, neuropsychiatric symptoms predominate and include dystonia, tremor, personality changes, and cognitive impairments secondary to copper accumulation in the central nervous system. The laboratory diagnosis of Wilson's disease is confirmed by decreased serum ceruloplasmin, increased urinary copper content, and elevated hepatic copper concentration. Molecular genetic analysis is complex as more than 100 unique mutations have been identified and most individuals are compound heterozygotes. Copper chelation with penicillamine is an effective therapy in most patients and hepatic transplantation is curative in individuals presenting with irreversible liver failure. Elucidation of the molecular genetic basis of Wilson's disease has permitted new insights into the mechanisms of cellular copper homeostasis.

    Aim To determine the frequency and the characteristics of cutaneous manifestations, especially vitiligo and alopecia areata, in patients with chronic graft-vs-host disease (cGVHD). Methods 50 patients with cGVHD were prospectively enrolled in the observational study protocol and evaluated by an experienced dermatologist. The evaluation was focused on the clinical spectrum of skin and adnexal involvement, and the cutaneous GVHD score was determined according to National Institutes of Health (NIH) Consensus criteria. The presence of vitiligo, alopecia, xerosis, nail changes, and dyspigmentation was also assessed. Results Out of 50 cGVHD patients, 28 (56%) had skin involvement, and 27 of them (96%) had hypo and/or hyperpigmentations. 11 patients (39%) had a mild cutaneous NIH cGVHD score, 22% moderate, and 39% severe. 15 (30%) patients had nail changes and 10 (20%) had vitiligo or alopecia areata. Univariate analysis showed that patients with vitiligo/alopecia areata received more lines of prior systemic immunosuppressive therapy (P = 0.043), had lower Karnofsky performance status (P = 0.028), and had a higher B-cell number (P = 0.005), platelet count (P = 0.022), and total protein (P = 0.024). Vitiligo and alopecia areata were associated with higher NIH skin score (P = 0.001), higher intensity of immunosuppressive treatment (P = 0.020), and total body irradiation conditioning (P = 0.040). Multivariate regression model showed that patients with higher NIH skin scoring were 3.67 times more likely to have alopecia and/or vitiligo (odds ratio 3.67; 95% confidence interval 1.26-10.73), controlled for all other factors in the model (age at study entry, number of B-cells, platelet count, and global NIH score). Conclusion These data indicate that vitiligo and alopecia areata occur more frequently in cGVHD than previously reported. PMID:27374824

    Health Issue Cardiovascular disease (CVD) is the leading cause of death in Canadian women and men. In general, women present with a wider range of symptoms, are more likely to delay seeking medial care and are less likely to be investigated and treated with evidence-based medications, angioplasty or coronary artery bypass graft than men. Key Findings In 1998, 78,964 Canadians died from CVD, almost half (39,197) were women. Acute myocardial infarction, which increases significantly after menopause, was the leading cause of death among women. Cardiovascular disease accounted for 21% of all hospital admissions for Canadian women over age 50 in 1999. Admissions to hospital for ischemic heart disease were more frequent for men, but the mean length of hospital stay was longer for women. Mean blood pressure increases with age in both men and women. After age 65, however, high blood pressure is more common among Canadian women. More than one-third of postmenopausal Canadian women have hypertension. Diabetes increases the mortality and morbidity associated with CVD in women more than it does in men. Depression also contributes to the incidence and recovery from CVD, particularly for women who experience twice the rate of depression as men. Data Gaps and Recommendations CVD needs to be recognized as a woman's health issue given Canadian mortality projections (particularly heart failure). Health professionals should be trained to screen, track, and address CVD risk factors among women, including hypertension, elevated lipid levels, smoking, physical inactivity, depression, diabetes and low socio-economic status.

    Calcium intake shows a small impact on bone mineral density and fracture risk. Denosumab is a more potent inhibitor of bone resorption than zoledronate. Abaloparatide, PTHrP analog, increases bone mineral density and decreases fracture incidence. Teriparatide could be delivered via a transdermic device. Romosozumab and odanacatib improve calculated bone strength. Sequential or combined treatments with denosumab and teriparatide could be of interest, but not denosumab followed by teriparatide.

    Although initially considered a localized epidemic form of arthritis. Lyme disease is now known to have protean manifestation (skin, joint, heart, nervous system) and worldwide distribution. It is caused by infection with the spirochaete Borrelia burgdorferi and is transmitted by a variety of hard ticks and, in some localities, fleas. Antigenic variation between isolates may determine the differences in clinical expression observed between cases in North America and Europe. The reservoir in the animal kingdom is primarily in deer and mice but house pets have also been implicated. The disease is easily treated with oral antibiotics (tetracycline or penicillin) at an early stage but requires parenteral penicillin and can become refractory to medication at late stages. Prompt diagnosis assures the best outcome. Whereas the classic rash, erythema chronicum migrans, is pathognomonic, diagnosis in its absence may rest on serological tests. Bacteriological isolation is seldom successful and is lengthy (Shrestha et al, 1985). Since cloning of the DNA for several of B. burgdorferi antigens has been accomplished, utilization of hybridization techniques may allow rapid detection of the presence of the organism and confirm difficult cases in the future.

    Purpose of review To summarize recent advances in celiac disease (CD) published between August 2008 and July 2009. Recent findings CD affects ~1% of most populations but remains largely unrecognized. In the last year, work has shown that the prevalence of CD has increased dramatically, not simply due to increased detection. Also, undiagnosed CD may be associated with increased mortality. Significant progress has been made in understanding how gliadin peptides can cross the intestinal border and access the immune system. New genetic loci and candidate genes that may contribute to the risk of CD and its overlap with type 1 diabetes mellitus have been identified. New deamidated gliadin peptides antibodies have better diagnostic accuracy over native gliadin-based tests. The inclusion of duodenal bulb biopsy specimens may increase the rate of CD detection. The spectrum of CD likely includes a minority of patients with mild enteropathy. A practical 7-item instrument may facilitate standardized evaluation of gluten-free diet adherence. Finally, refractory CD, whilst rare, is associated with a poor prognosis. Summary Celiac disease is a global health problem that requires a multidisciplinary and increasingly cooperative multinational research effort. PMID:20040864

    For the first time in literature the authors interpret the pathography of Refsum's disease, in the case of their patient, as pseudo-hypervitaminosis A. The biochemical basis of the clinical picture is a defect in the activity of phytanic-acid-alpha-hydrolase belonging to the peroxisomal system. As a consequence, phytanic acid accumulates in the serum and in the parenchymal tissues. Retinol, an alcohol with high molecular weight, is a natural ligand of nuclear RXR (retinoid-X-receptor), which plays an important role in the regulation of peroxisoma synthesis. In Refsum's disease the phytanic acid accumulated because of the enzyme defect competes with the biotransformation derivates (all-trans-retinoic acid, 9-cis-retinoic acid) of the all-trans-retinol (vitamin A) for the nuclear RX receptor binding sites, and as a very potent receptoractivator it causes the intestinal symptoms of hypervitaminosis A. The authors review the procedure of fatty-acid chromatography necessary for the establishment of the diagnosis and discuss--in addition to dietary restrictions--recent therapeutic possibilities, like plasmapheresis, cascade filtration, lipapheresis and oral batylalcohol treatment.

    Chagas' disease, caused by Trypanosoma cruzi, is an important cause of morbidity in many countries in Latin America. The important modes of transmission are by the bite of the reduviid bug and blood transfusion. The organism exists in three morphological forms: trypomastigotes, amastigotes, and epimastigotes. The mechanism of transformation and differentiation is currently being explored, and signal transduction pathways of the parasites may be involved in this process. Parasite adherence to and invasion of host cells is a complex process involving complement, phospholipase, penetrin, neuraminidase, and hemolysin. Two clinical forms of the disease are recognized, acute and chronic. During the acute stage pathological damage is related to the presence of the parasite, whereas in the chronic stage few parasites are found. In recent years the roles of tumor necrosis factor, gamma interferon, and the interleukins in the pathogenesis of this infection have been reported. The common manifestations of chronic cardiomyopathy are arrhythmias and thromboembolic events. Autoimmune, neurogenic, and microvascular factors may be important in the pathogenesis of the cardiomyopathy. The gastrointestinal tract is another important target, and "mega syndromes" are common manifestations. The diagnosis and treatment of this infection are active areas of investigation. New serological and molecular biological techniques have improved the diagnosis of chronic infection. Exacerbations of T. cruzi infection have been reported for patients receiving immuno-suppressive therapy and for those with AIDS. Images PMID:1423218

    Alzheimer's disease (AD) is a chronic neurodegenerative disease with well-defined pathophysiological mechanisms, mostly affecting medial temporal lobe and associative neocortical structures. Neuritic plaques and neurofibrillary tangles represent the pathological hallmarks of AD, and are respectively related to the accumulation of the amyloid-beta peptide (Aβ) in brain tissues, and to cytoskeletal changes that arise from the hyperphosphorylation of microtubule-associated Tau protein in neurons. According to the amyloid hypothesis of AD, the overproduction of Aβ is a consequence of the disruption of homeostatic processes that regulate the proteolytic cleavage of the amyloid precursor protein (APP). Genetic, age-related and environmental factors contribute to a metabolic shift favoring the amyloidogenic processing of APP in detriment of the physiological, secretory pathway. Aβ peptides are generated by the successive cleavage of APP by beta-secretase (BACE-1) and gamma-secretase, which has been recently characterized as part of the presenilin complex. Among several beta-amyloid isoforms that bear subtle differences depending on the number of C-terminal amino acids, Aβ (1-42) plays a pivotal role in the pathogenesis of AD. The neurotoxic potential of the Aβ peptide results from its biochemical properties that favor aggregation into insoluble oligomers and protofibrils. These further originate fibrillary Aβ species that accumulate into senile and neuritic plaques. These processes, along with a reduction of Aβ clearance from the brain, leads to the extracellular accumulation of Aβ, and the subsequent activation of neurotoxic cascades that ultimately lead to cytoskeletal changes, neuronal dysfunction and cellular death. Intracerebral amyloidosis develops in AD patients in an age-dependent manner, but recent evidence indicate that it may be observed in some subjects as early as in the third or fourth decades of life, with increasing magnitude in late middle age

    The author presents his personal choice of practical relevant papers of pancreatic diseases from 2014 to 2015. Nutritional factors and hypertriglycidemia are discussed as causes of acute pancreatitis. Tools to avoid post-ERCP(endoscopic retrograde cholangiopancreatography) pancreatitis are described and the natural course of fluid collections and pseudocysts is demonstrated. The value of secretin-MRCP(magnetic resonance cholangiopancreatography) for diagnosis of chronic pancreatitis is illustrated. Data help to choose the minimally effective prednisolone dose in autoimmune pancreatitis. The increased prevalence of fractures in patients with chronic pancreatitis highlights the necessity of screening for bone density loss. The association of vitamin D intake with pancreatic cancer is described. The probability of cancer in IPNM is shown and innovative surgical concepts to reduce the loss of pancreatic function are presented. Finally neoadjuvant concepts for the treatment of pancreatic cancer are highlighted. PMID:27329710

    Disease activity refers to potentially reversible aspects of a disease. Measurement of disease activity in paediatric rheumatic diseases is a critical component of patient care and clinical research. Disease activity measures are developed systematically, often involving consensus methods. To be useful, a disease activity measure must be feasible, valid, and interpretable. There are several challenges in quantifying disease activity in paediatric rheumatology; namely, the conditions are multidimensional, the level of activity must be valuated in the context of treatment being received, there is no gold standard for disease activity, and it is often difficult to incorporate the patient's perspective of their disease activity. To date, core sets of response variables are defined for juvenile idiopathic arthritis, juvenile systemic lupus erythematosus, and juvenile dermatomyositis, as well as definitions for improvement in response to therapy. Several specific absolute disease activity measures also exist for each condition. Further work is required to determine the optimal disease activity measures in paediatric rheumatology.

    Vibroacoustic disease (VAD) is a whole-body, systemic pathology, characterized by the abnormal proliferation of extra-cellular matrices, and caused by excessive exposure to low frequency noise (LFN). VAD has been observed in LFN-exposed professionals, such as, aircraft technicians, commercial and military pilots and cabin crewmembers, ship machinists, restaurant workers, and disk-jockeys. VAD has also been observed in several populations exposed to environmental LFN. This report summarizes what is known to date on VAD, LFN-induced pathology, and related issues. In 1987, the first autopsy of a deceased VAD patient was performed. The extent of LFN induced damage was overwhelming, and the information obtained is, still today, guiding many of the associated and ongoing research projects. In 1992, LFN-exposed animal models began to be studied in order to gain a deeper knowledge of how tissues respond to this acoustic stressor. In both human and animal models, LFN exposure causes thickening of cardiovascular structures. Indeed, pericardial thickening with no inflammatory process, and in the absence of diastolic dysfunction, is the hallmark of VAD. Depressions, increased irritability and aggressiveness, a tendency for isolation, and decreased cognitive skills are all part of the clinical picture of VAD. LFN is a demonstrated genotoxic agent, inducing an increased frequency of sister chromatid exchanges in both human and animal models. The occurrence of malignancies among LFN-exposed humans, and of metaplastic and displastic appearances in LFN-exposed animals, clearly corroborates the mutagenic outcome of LFN exposure. The inadequacy of currently established legislation regarding noise assessments is a powerful hindrance to scientific advancement. VAD can never be fully recognized as an occupational and environmental pathology unless the agent of disease--LFN--is acknowledged and properly evaluated. The worldwide suffering of LFN-exposed individuals is staggering and it is

    The incidence of pregnant women with thyroid dysfunction has been reported to be around 0.1-0.4%. Graves' disease accounts for more than half of these disorders. The main cause of thyroid disease in pregnancy and puerperium is autoimmune dysfunction. Whether there may be goitre or exophthalmus present, clinical signs as inappropriate weight gain, high systolic pressure, palpitation (greater than or equal to 110/min), emotional lability, fatigue, acceleration of suppression of the Achilles' tendon reflex should induce changes in the biochemical thyroid function tests. Parameters for the diagnosis and management for hyperthyroidism are serum levels of free T4 and TSH, while those of T3, reverse T3, and TSH are for hypothyroidism. Serum anti-microsomal antibodies and anti-thyroglobulin antibodies which have no effect on the fetus are also good markers for severity. The transplacental transfer of maternal TSH receptor antibodies consisting of stimulatory and inhibitory immunoglobulins and maternal thyroid-binding inhibiting immunoglobulins play roles in the development of transient neonatal hyper- or hypothyroidism. Fetal control is achieved by optimal maternal management. Untreated hyperthyroidism may be associated with fetal malformations. This risk may be reduced by antithyroid drug treatment of up to 150 mg/day of propylthiouracil which has less chance of placental passage and less secretion into the mother's milk than methyl-mercapto-imidazol. Maternal thyroid function should be kept in the upper limit of normal range, taking into consideration the fetal dysfunction induced by over-administration of the drug which passes through placenta. Children of hypothyroid women taking inadequate replacement therapy manifested lower IQ values compared to the progeny of euthyroid or hypothyroid women taking adequate therapy.(ABSTRACT TRUNCATED AT 250 WORDS)

    Meniere's disease (MD) is a disorder of the inner ear that causes vertigo attacks, fluctuating hearing loss, tinnitus and aural fullness. The aetiology of MD is multifactorial. A characteristic sign of MD is endolymphatic hydrops (EH), a disorder in which excessive endolymph accumulates in the inner ear and causes damage to the ganglion cells. In most patients, the clinical symptoms of MD present after considerable accumulation of endolymph has occurred. However, some patients develop symptoms in the early stages of EH. The reason for the variability in the symptomatology is unknown and the relationship between EH and the clinical symptoms of MD requires further study. The diagnosis of MD is based on clinical symptoms but can be complemented with functional inner ear tests, including audiometry, vestibular-evoked myogenic potential testing, caloric testing, electrocochleography or head impulse tests. MRI has been optimized to directly visualize EH in the cochlea, vestibule and semicircular canals, and its use is shifting from the research setting to the clinic. The management of MD is mainly aimed at the relief of acute attacks of vertigo and the prevention of recurrent attacks. Therapeutic options are based on empirical evidence and include the management of risk factors and a conservative approach as the first line of treatment. When medical treatment is unable to suppress vertigo attacks, intratympanic gentamicin therapy or endolymphatic sac decompression surgery is usually considered. This Primer covers the pathophysiology, symptomatology, diagnosis, management, quality of life and prevention of MD. PMID:27170253

After laying aside other ethiologies, and understanding as Castleman Multicentric disease, it is started to supply prednisona 1 mg/kg of weight with a clinical and biochemical fast and outstanding response. After 7 months it was progressively suspended the esteroids and 60 days later, the process fall back; for that, corticoids are restarted, with a good evolution. The illness of Castleman although it is not very frequent, it should be considered as differential diagnosis in those clinical cases that are accompanied with important general commitment, linphadenopaties and respons to steroid therapy.

    Wilson disease and cholestatic liver diseases may present as a diagnostic dilemma if standard guidelines incorporating markers of copper overload are followed. We hereby present a series of four cases of sclerosing cholangitis masquerading as Wilson disease. True Wilson disease cases had significantly lower ceruloplasmin (6 vs. 16 mg/dL) and higher 24-hour urinary copper (322.3 vs. 74.5 μg/day) as compared to mimickers. Initial low serum ceruloplasmin levels normalized in mimickers on follow up, and this may used as a diagnostic indicator. Standard Wilson disease diagnostic criteria thus need further modification especially in developing countries to help avoid mismanagement.

    The growing body of transcriptomic, proteomic, metabolomic and genomic data generated from disease states provides a great opportunity to improve our current understanding of the molecular mechanisms driving diseases and shared between diseases. The use of both clinical and molecular phenotypes will lead to better disease understanding and classification. In this study, we set out to gain novel insights into diseases and their relationships by utilising knowledge gained from system-level molecular data. We integrated different types of biological data including genome-wide association studies data, disease-chemical associations, biological pathways and Gene Ontology annotations into an Integrated Disease Network (IDN), a heterogeneous network where nodes are bio-entities and edges between nodes represent their associations. We also introduced a novel disease similarity measure to infer disease-disease associations from the IDN. Our predicted associations were systemically evaluated against the Medical Subject Heading classification and a statistical measure of disease co-occurrence in PubMed. The strong correlation between our predictions and co-occurrence associations indicated the ability of our approach to recover known disease associations. Furthermore, we presented a case study of Crohn's disease. We demonstrated that our approach not only identified well-established connections between Crohn's disease and other diseases, but also revealed new, interesting connections consistent with emerging literature. Our approach also enabled ready access to the knowledge supporting these new connections, making this a powerful approach for exploring connections between diseases.

    An 11-year-old Tanzanian girl presented with diffuse verrucous lesions of varying morphology, scarring alopecia, and keloid scars over the face with a predilection for the ears. Physical examination revealed dark keratoderma and patches of hypopigmentation near the midline of the dorsal trunk (Figure 1a). Her forearms were densely covered by verrucous lesions with the exception of a clear linear patch on the dorsal aspect of the left forearm (Figure 1b). The perioral area was notable for white spires projecting from verrucous papules (Figure 1c) while the oral mucosa and teeth appeared normal on visual examination. The rest of her body, including the palms and soles, was covered by patchy, scaly lesions of varying severity. PMID:27502264

    Antecedente: el carcinoma triquilemal es una neoplasia maligna poco frecuente originada en los anexos de la piel. Debido a su escasa prevalencia suele confundirse con otros tumores dérmicos, su presentación clínica no favorece el diagnóstico diferencial y generalmente éste se hace por exclusión. En teoría, su comportamiento es lento, con poca tendencia a enviar metástasis regionales ganglionares y sistémicas. Debido al escaso número de casos no existe consenso en relación con el pronóstico, aunque generalmente se estima bueno. El objetivo de este reporte es mostrar un caso que, contrario a lo informado, es de manifestación agresiva en un paciente sin factores de riesgo para cáncer de piel, con gran infiltración tumoral de los tejidos blandos alrededor del sitio de origen. Caso clínico: paciente masculino de 65 años de edad que acudió con diagnóstico citológico de carcinoma en un tumor facial preparotídeo; al momento del diagnóstico motraba infiltración de la piel de la cara, del pabellón auricular y de la glándula parótida. Se efectuó resección completa de la neoplasia en bloque con isla de piel facial, parotidectomía total y disección radical del cuello; el defecto de partes blandas fue cubierto con un colgajo pediculado. La evolución ha sido satisfactoria; sin embargo, el seguimiento es corto. Se evalúa la experiencia asentada en la bibliografía en relación con el pronóstico y tratamiento de estos pacientes. Conclusión: el carcinoma triquilemal puede tener comportamiento localmente invasor lo que hace difícil determinar el pronóstico, que quizá dependa de la etapa clínica al momento del diagnóstico.

    Solitary fibrous tumor is a rare, benign spindle cell neoplasm that was first described in the thoracic pleura. This tumor is now known to occur at many extrapleural sites. There are established criteria for the diagnosis of malignant solitary fibrous tumor including ≥4 mitotic figures per 10 high-power fields, increased cellularity, cytologic atypia, infiltrative margins, and/or necrosis. Although all solitary fibrous tumors have the potential to recur or metastasize, those with malignant histologic features tend to behave more aggressively. We report a case of solitary fibrous tumor, with malignant histologic features, in a 21-year-old woman which arose from the serosal surface of the sigmoid colon. PMID:27672467

    2013-02-01

    Wilson's disease is a hereditary autosomal recessive disorder of copper metabolism,characterized by copper accumulation in the liver and brain. This rare entity, which has a broad clinical spectrum, is often difficult to diagnose and should therefore always be suspected in patients with liver disease of unclear cause. We describe two types of manifestation of liver disease in two patients; the first developed fulminant hepatic failure requiring urgent liver transplantation and the second showed advanced chronic liver disease and received standard medical treatment. The objective of this clinical observation is to analyze the diagnosis of Wilson's disease in two patients with distinct onset, illustrating the broad clinical spectrum of the disease, and its treatment.

    2015-11-01

    Cardiovascular disease is increasingly recognized as a major cause of premature mortality among those with autoimmune disorders. There is an urgent need to identify those patients with autoimmune disease who are at risk for CVD so as to optimize therapeutic intervention and ultimately prevention. Accurate identification, monitoring and stratification of such patients will depend upon a panel of biomarkers of cardiovascular disease. This review will discuss some of the most recent biomarkers of cardiovascular diseases in autoimmune disease, including lipid oxidation, imaging biomarkers to characterize coronary calcium, plaque, and intima media thickness, biomarkers of inflammation and activated complement, genetic markers, endothelial biomarkers, and antiphospholipid antibodies. Clinical implementation of these biomarkers will not only enhance patient care but also likely accelerate the pharmaceutical pipeline for targeted intervention to reduce or eliminate cardiovascular disease in the setting of autoimmunity.

    The complete human genome sequence will facilitate the identification of all genes that contribute to disease. We propose that the functional classification of disease genes and their products will reveal general principles of human disease. We have determined functional categories for nearly 1,000 documented disease genes, and found striking correlations between the function of the gene product and features of disease, such as age of onset and mode of inheritance. As knowledge of disease genes grows, including those contributing to complex traits, more sophisticated analyses will be possible; their results will yield a deeper understanding of disease and an enhanced integration of medicine with biology.

    Gingivitis and periodontitis are immunoinflammatory periodontal diseases characterized by chronic localized infections usually associated with insidious inflammation This narrative review discusses periodontal diseases and mechanisms influencing the immune response and autoimmunity in pediatric rheumatic diseases (PRD), particularly juvenile idiopathic arthritis (JIA), childhood-onset systemic lupus erythematosus (C-SLE) and juvenile dermatomyositis (JDM). Gingivitis was more frequently observed in these diseases compared to health controls, whereas periodontitis was a rare finding. In JIA patients, gingivitis and periodontitis were related to mechanical factors, chronic arthritis with functional disability, dysregulation of the immunoinflammatory response, diet and drugs, mainly corticosteroids and cyclosporine. In C-SLE, gingivitis was associated with longer disease period, high doses of corticosteroids, B-cell hyperactivation and immunoglobulin G elevation. There are scarce data on periodontal diseases in JDM population, and a unique gingival pattern, characterized by gingival erythema, capillary dilation and bush-loop formation, was observed in active patients. In conclusion, gingivitis was the most common periodontal disease in PRD. The observed association with disease activity reinforces the need for future studies to determine if resolution of this complication will influence disease course or severity.

  2. Prion diseases as transmissible zoonotic diseases.

    2013-02-01

    Prion diseases, also called transmissible spongiform encephalopathies (TSEs), lead to neurological dysfunction in animals and are fatal. Infectious prion proteins are causative agents of many mammalian TSEs, including scrapie (in sheep), chronic wasting disease (in deer and elk), bovine spongiform encephalopathy (BSE; in cattle), and Creutzfeldt-Jakob disease (CJD; in humans). BSE, better known as mad cow disease, is among the many recently discovered zoonotic diseases. BSE cases were first reported in the United Kingdom in 1986. Variant CJD (vCJD) is a disease that was first detected in 1996, which affects humans and is linked to the BSE epidemic in cattle. vCJD is presumed to be caused by consumption of contaminated meat and other food products derived from affected cattle. The BSE epidemic peaked in 1992 and decreased thereafter; this decline is continuing sharply owing to intensive surveillance and screening programs in the Western world. However, there are still new outbreaks and/or progression of prion diseases, including atypical BSE, and iatrogenic CJD and vCJD via organ transplantation and blood transfusion. This paper summarizes studies on prions, particularly on prion molecular mechanisms, BSE, vCJD, and diagnostic procedures. Risk perception and communication policies of the European Union for the prevention of prion diseases are also addressed to provide recommendations for appropriate government policies in Korea.

    Cardiovascular disease is the most common cause of mortality in rich countries and today it has the same meaning for health care as the epidemics of past centuries had for medicine in earlier times: 50% of the population in these countries die of cardiovascular disease. The amount of cardiovascular disease is also increasing in the developing countries together with economic growth. By 2015 one in three deaths will globally be due to cardiovascular diseases. Coronary heart disease is a chronic disease that starts in childhood, even if the symptoms first occur in the middle age. The risks for coronary heart disease are well-known: lipid disorders, especially high serum LDL-cholesterol concentration, high blood pressure, tobacco smoking, obesity, diabetes, male gender and physical inactivity. Obesity is both an independent risk factor for cardiovascular disease but is also closely connected with several other risk factors. This review focuses on the connection between overweight or obesity and cardiovascular disease. PMID:25387321

    Names are more than just labels used to identify diseases. They can be windows into the discovery, characteristics and attributes of the disease. Toponymous diseases are diseases that are named after places. Hendra, Ross River, Bairnsdale, Murray Valley and Barmah Forest are all examples of Australian places that have had diseases named after them. They all have unique and interesting stories that provide a glimpse into their discovery, history and culture. Because of perceived negative connotations, the association of diseases with placenames has sometimes generated controversy. PMID:21143049

    Since the revision of Clinical Diagnostic Criteria for Autoimmune Pancreatitis (AIP) 2006, many cases of localized AIP have been reported. Localized AIP is often difficult to preoperatively differentiate from pancreatic carcinoma. We present two cases of localized AIP that developing relapse after surgical treatment. Swollen hilar lymph nodes of lung was detected on CT in both two cases. Recently, AIP is thought to be the pancreatic manifestation of an IgG4 related systemic disease, which has been associated with many extrapancreatic lesions. Response to steroid treatment and the detection of extrapancreatic lesions may contribute to provide adequate diagnosis thereby avoiding unnecessary surgery.

    In recent years, emerging diseases were defined as being infectious, acquiring high incidence, often suddenly, or being a threat or an unexpected phenomenon. This study discusses the hallmarks of emerging diseases, describing the existence of noninfectious emerging diseases, and elaborating on the advantages of defining noninfectious diseases as emerging ones. From the discussion of various mental health disorders, nutritional deficiencies, external injuries and violence outcomes, work injuries and occupational health, and diseases due to environmental factors, the conclusion is drawn that a wide variety of noninfectious diseases can be defined as emergent. Noninfectious emerging diseases need to be identified in order to improve their control and management. A new definition of "emergent disease" is proposed, one that emphasizes the pathways of emergence and conceptual traits, rather than descriptive features.

  4. Celiac Disease: Diagnosis.

    PubMed

    Byrne, Greg; Feighery, Conleth F

    2015-01-01

    Historically the diagnosis of celiac disease has relied upon clinical, serological, and histological evidence. In recent years the use of sensitive serological methods has meant an increase in the diagnosis of celiac disease. The heterogeneous nature of the disorder presents a challenge in the study and diagnosis of the disease with patients varying from subclinical or latent disease to patients with overt symptoms. Furthermore the related gluten-sensitive disease dermatitis herpetiformis, while distinct in some respects, shares clinical and serological features with celiac disease. Here we summarize current best practice for the diagnosis of celiac disease and briefly discuss newer approaches. The advent of next-generation assays for diagnosis and newer clinical protocols may result in more sensitive screening and ultimately the possible replacement of the intestinal biopsy as the gold standard for celiac disease diagnosis.

  1. Disease control operations

    Friend, Milton; Franson, J. Christian

    1987-01-01

    Individual disease outbreaks have killed many thousands of animals on numerous occasions. Tens of thousands of migratory birds have died in single die-offs with as many as 1,000 birds succumbing in 1 day. In mammals, individual disease outbreaks have killed hundreds to thousands of animals with, for example, hemorrhagic disease in white-tailed deer, distemper in raccoon, Errington's disease in muskrat, and sylvatic plague in wild rodents. The ability to successfully combat such explosive situations is highly dependent n the readiness of field personnel to deal with them. Because many disease agents can spread though wildlife populations very fast, advance preparation is essential in preventing infected animals from spreading disease to additional species and locations. Carefully though-out disease contingency plans should be developed as practical working documents for field personnel and updated as necessary. Such well-designed plans can prove invaluable in minimizing wildlife losses and costs associated with disease control activities. Although requirements for disease control operations vary and must be tailored to each situation, all disease contingency planning involved general concepts and basic biological information. This chapter, intended as a practical guide, identifies the major activities and needs of disease control operations, and relates them to disease contingency planning.

  11. Mechanisms of disease: defensins in gastrointestinal diseases.

    PubMed

    Wehkamp, Jan; Fellermann, Klaus; Herrlinger, Klaus R; Bevins, Charles L; Stange, Eduard F

    2005-09-01

    Defensins are endogenous antibiotics with microbicidal activity against Gram-negative and Gram-positive bacteria, fungi, viruses and protozoa. In the gastrointestinal tract, defensins help regulate the composition and number of colonizing microbes, and protect the host from food-borne and water-borne pathogens. In health, the normal host relationship with the commensal luminal microbiota is beneficial, but the same commensal bacteria could have a pathogenic role in inflammatory diseases. A disturbance in antimicrobial defense, as provided by Paneth cells of the small intestine, seems to be a critical factor in the pathogenesis of ileal Crohn's disease, an inflammatory disease of the intestinal tract. The disruption of the critical balance between antimicrobial peptides and luminal bacteria might also explain other gastrointestinal infections and diseases. Elucidating the underlying mechanisms involved in the regulation and biology of defensins could open up new therapeutic avenues.

  12. Cerebrovascular disease in ageing and Alzheimer's disease.

    PubMed

    Love, Seth; Miners, J Scott

    2016-05-01

    Cerebrovascular disease (CVD) and Alzheimer's disease (AD) have more in common than their association with ageing. They share risk factors and overlap neuropathologically. Most patients with AD have Aβ amyloid angiopathy and degenerative changes affecting capillaries, and many have ischaemic parenchymal abnormalities. Structural vascular disease contributes to the ischaemic abnormalities in some patients with AD. However, the stereotyped progression of hypoperfusion in this disease, affecting first the precuneus and cingulate gyrus, then the frontal and temporal cortex and lastly the occipital cortex, suggests that other factors are more important, particularly in early disease. Whilst demand for oxygen and glucose falls in late disease, functional MRI, near infrared spectroscopy to measure the saturation of haemoglobin by oxygen, and biochemical analysis of myelin proteins with differential susceptibility to reduced oxygenation have all shown that the reduction in blood flow in AD is primarily a problem of inadequate blood supply, not reduced metabolic demand. Increasing evidence points to non-structural vascular dysfunction rather than structural abnormalities of vessel walls as the main cause of cerebral hypoperfusion in AD. Several mediators are probably responsible. One that is emerging as a major contributor is the vasoconstrictor endothelin-1 (EDN1). Whilst there is clearly an additive component to the clinical and pathological effects of hypoperfusion and AD, experimental and clinical observations suggest that the disease processes also interact mechanistically at a cellular level in a manner that exacerbates both. The elucidation of some of the mechanisms responsible for hypoperfusion in AD and for the interactions between CVD and AD has led to the identification of several novel therapeutic approaches that have the potential to ameliorate ischaemic damage and slow the progression of neurodegenerative disease.

  13. [Is Parkinson's disease a prion disease?].

    PubMed

    Brandel, J-P; Corbillé, A-G; Derkinderen, P; Haïk, S

    2015-12-01

    The accumulation of a specific protein in aggregated form is a common phenomenon in human neurodegenerative diseases. In Parkinson's disease, this protein is α-synuclein which is a neuronal protein of 143 amino acids. With a monomeric conformation in solution, it also has a natural capacity to aggregate into amyloid structures (dimers, oligomers, fibrils and Lewy bodies or neurites). It therefore fulfils the characteristics of a prion protein (different conformations, seeding and spreading). In vitro and in vivo experimental evidence in transgenic and wild animals indicates a prion-like propagation of Parkinson's disease. The sequential and predictive distribution of α-synuclein demonstrated by Braak et al. and its correlation with non-motor signs are consistent with the prion-like progression. Although the triggering factor causing the misfolding and aggregation of the target protein is unknown, Parkinson's disease is a highly relevant model for the study of these mechanisms and also to test specific treatments targeting the assemblies of α-synuclein and propagation from pre-motor phase of the disease. Despite this prion-like progression, there is currently no argument indicating a risk of human transmission of Parkinson's disease. PMID:26563663

    2015-09-15

    Parkinson's disease (PD) is an increasingly prevalent and progressively disabling neurodegenerative disease. The impact of PD on patients and their families as well as its burden on health care systems could be substantially reduced by disease-modifying therapies that slow the rate of neurodegeneration or stop the disease process. Multiple agents have been studied in clinical trials designed to assess disease modification in PD, but all have failed. Over the last 3 years, clinical trials investigating the potential of adeno-associated virus serotype 2 (AAV)-neuturin, coenzyme Q10, creatine, pramipexole, and pioglitazone reported negative findings or futility. Despite these disappointments, progress has been made by expanding our understanding of molecular pathways involved in PD to reveal new targets, and by developing novel animal models of PD for preclinical studies. Currently, at least eight ongoing clinical trials are testing the promise of isradipine, caffeine, nicotine, glutathione, AAV2-glial cell-line derived neurotrophic factor (GDNF), as well as active and passive immunization against α-synuclein (α-Syn). In this review, we summarize the clinical trials of disease-modifying therapies for PD that were published since 2013 as well as clinical trials currently in progress. We also discuss promising approaches and ongoing challenges in this area of PD research.

    Although our current understanding is limited, epidemiologic investigation of Crohn's disease holds great promise. Certain aspects of the epidemiology are clear. The incidence of Crohn's disease, which has increased over the past few decades, may have reached a plateau. The disease has its peak onset in early life, with a second peak among the elderly. It is more common in the developed countries and among Jews. Whether the disease is related to occupation, social class, marital status, stress, infection, diet, smoking, and oral contraceptives is less certain. This paper reviews the epidemiology of Crohn's disease and proposes areas in which further research is needed.

    Neurodegenerative diseases pose a significant problem for the healthcare system, doctors, and patients. With an aging population, more and more individuals are developing neurodegenerative diseases and there are few treatment options at the present time. Meditation techniques present an interesting potential adjuvant treatment for patients with neurodegenerative diseases and have the advantage of being inexpensive, and easy to teach and perform. There is increasing research evidence to support the application of meditation techniques to help improve cognition and memory in patients with neurodegenerative diseases. This review discusses the current data on meditation, memory, and attention, and the potential applications of meditation techniques in patients with neurodegenerative diseases.

    Lyme disease, a bacterial infection transmitted by ticks, is the most common vector-borne disease in the northern hemisphere. Athletes who train or compete in wooded environments in endemic regions are at increased risk of contracting Lyme disease. Variability in clinical presentation, masquerading symptoms, and limitations in testing may lead to misdiagnosis. Early diagnosis and treatment result in full recovery for most patients with Lyme disease; however symptoms may persist for months to years, especially when diagnosis is delayed. This article reviews the epidemiology, clinical manifestations, diagnosis, treatment, and prevention of Lyme disease, with focus on the athletic population.

    2016-01-01

    Inflammation response plays an important role in host survival, and it also leads to acute and chronic inflammatory diseases such as rheumatoid arthritis, bowel diseases, allergic rhinitis, asthma, atopic dermatitis and various neurodegenerative diseases. During the course of inflammation, the ROS level increases. In addition to ROS, several inflammatory mediators produced at the site lead to numerous cell-mediated damages. Inflammatory bowel disease (IBD), including ulcerative colitis and Crohn's disease, is a chronic intestinal disorder resulting from a dysfunctional epithelial, innate and adaptive immune response to intestinal microorganisms. The methods involving indomethacin-induced enterocolitis in rats with macroscopic changes of IBD, myeloperoxidase assay, microscopic (histologic) characters and biochemical parameters are discussed.

    Investigators have found a restriction enzyme marker, a piece of DNA that can be located with recombinant DNA techniques, that is so close to the Huntington's disease gene that its presence can be used as an indicator for that gene. If this marker is used as a diagnostic test for Huntington's disease, people at risk for getting the disease will be able to learn whether or not they will in fact develop the disease. The ability to predict the inevitable onset of this progressive, degenerative disease raises ethical questions about counseling, screening, and disclosure of risk status to patients and family members.

    Prion disease is the new designation of a group of spongiform encephalopathies, all invariably fatal, which show similar clinical and neuropathological changes. They comprise a range of distinct diseases in both animals and man, and spontaneous, hereditary and transmissible forms are recognized. Until the sudden occurrence in the mid-1980s of an epizootic of a formerly unknown disease, popularly named 'mad cow disease', in cattle in the UK, very little attention had been paid to these rather obscure diseases. Concurrently it was asserted that the disease-causing agent appeared to be a ubiquitous mammalian brain constituent, and the disease mechanism a conformational change of its structure. These events have not only led to a new understanding of these extraordinary diseases, but have also provided insight into both neurodegeneration and disease mechanisms at the molecular level. Moreover, in 1997 the prion concept earned its originator the second Nobel price for medicine within this scientific field. In this introduction and overview of prion diseases, historical and philosophical perspectives are presented along with descriptions of the diseases in both animals and man. Epidemiology, genetics and transmissibility are also covered. PMID:12064253

    Background Increasing volumes of data and computational capacity afford unprecedented opportunities to scale up infectious disease (ID) mapping for public health uses. Whilst a large number of IDs show global spatial variation, comprehensive knowledge of these geographic patterns is poor. Here we use an objective method to prioritise mapping efforts to begin to address the large deficit in global disease maps currently available. Methodology/Principal Findings Automation of ID mapping requires bespoke methodological adjustments tailored to the epidemiological characteristics of different types of diseases. Diseases were therefore grouped into 33 clusters based upon taxonomic divisions and shared epidemiological characteristics. Disability-adjusted life years, derived from the Global Burden of Disease 2013 study, were used as a globally consistent metric of disease burden. A review of global health stakeholders, existing literature and national health priorities was undertaken to assess relative interest in the diseases. The clusters were ranked by combining both metrics, which identified 44 diseases of main concern within 15 principle clusters. Whilst malaria, HIV and tuberculosis were the highest priority due to their considerable burden, the high priority clusters were dominated by neglected tropical diseases and vector-borne parasites. Conclusions/Significance A quantitative, easily-updated and flexible framework for prioritising diseases is presented here. The study identifies a possible future strategy for those diseases where significant knowledge gaps remain, as well as recognising those where global mapping programs have already made significant progress. For many conditions, potential shared epidemiological information has yet to be exploited. PMID:26061527

    Coeliac disease is a chronic autoimmune enteropathy, which is caused by exposure to dietary gluten in genetically pre-disposed individuals. -Approximately 0.5-1% of the Dutch population has coeliac disease, diag-nosed at both younger and older age. Treatment consists of a strict gluten-free diet. Symptoms can be diverse, including dental and oral manifestations. These dental and oral manifestations are often seen in patients with coeliac disease, although most of them are nonspecific. This is not the case for the symmetric enamel defects described by Aine and colleagues, which are very specific for coeliac disease. Early diagnosing of coeliac disease is important to prevent complications by (vitamin) deficiencies or rare (pre) malignant forms of coeliac disease. There seems to be a role for dentists in early diagnosing of coeliac disease.

    PubMed

    Lapcević, Mirjana

    2005-10-01

    Autoimmune thyroid disease (ATD) is a multifactorial, genetic disease. It is the sequelae of the impaired immunoregulation, tolerance and poor recognition of one's own proteins, oligopolysaccharides and polypeptides, due to development of somatic lymphocyte mutations. It is manifested by different clinical and morphological entities, inter-related by etiopathogenetic association, i.e., all of them are caused by disorder of immune system regulation. Chronic autoimmune thyroidism (Thyreoiditis lymphocytaria Hashimoto, HT), as well as immunogenic hyperthyroidism (Morbus Graves Basedow, MGB) are frequently associated with autoimmune diseases of other organs, such as: chronic insufficiency of salivary glands (Sy Sjögren), autoimmune hemolytic anemia, megalocytic pernicious anemia, thrombocytopenia, Rheumatoid arthritis, Diabetes mellitus (more often type 2, but also type 1), Morbus Addison, Coeliakia, and other autoimmune diseases such as systemic diseases of connecting tissue (Lupus erythematosus-SLE, Sclerodermia, Vasculitis superficialis). The incidence of autoimmune diseases has been at increase in all age groups of our population. The prevalence of organ-specific and organ-nonspecific antibodies increases with the age. Antigenicity of thyroid epithelial cell may be triggered by different chemical and biological agents (repeated viral infections), repeated stress, and in individuals with genetic propensity. Unrecognized ATD progressively leads to hypothyroidism with hyperlipidemia, blood vessel changes, osteoporosis, deformities, invalidity which substantially reduces the quality of life of patient and requires medical attention and expensive treatment on what account it is medically and socio-economically significant. Multiple diagnostic procedures contribute to faster recognition of this condition. The goal of the primary health care physician (given that preclinical phase of ATD and other associated diseases have different duration) and other specialists is to

    2015-01-01

    The optimal method for monitoring quiescent disease in patients with Crohn’s disease (CD) and ulcerative colitis is yet to be determined. Endoscopic evaluation with ileocolonoscopy is the gold standard but is invasive, costly, and time-consuming. There are many commercially available biomarkers that may be used in clinical practice to evaluate disease status in patients with inflammatory bowel disease (IBD), but the most widely adopted biomarkers are C-reactive protein (CRP) and fecal calprotectin (FC). This review summarizes the evidence for utilizing CRP and FC for monitoring IBD during clinical remission and after surgical resection. Endoscopic correlation with CRP and FC is evaluated in each disease state. Advantages and drawbacks of each biomarker are discussed with special consideration of isolated ileal CD. Fecal immunochemical testing, traditionally used for colorectal cancer screening, is mentioned as a potential new alternative assay in the evaluation of IBD. Based on a mixture of information gleaned from biomarkers, clinical status, and endoscopic evaluation, the best treatment decisions can be made for the patient with IBD. PMID:26523100

    Epigenetic marks in an organism can be altered by environmental factors throughout life. Although changes in the epigenetic code can be positive, some are associated with severe diseases, in particular, cancer and neuropsychiatric disorders. Recent evidence has indicated that certain epigenetic marks can be inherited, and reshape developmental and cellular features over generations. This review examines the challenging possibility that epigenetic changes induced by environmental factors can contribute to some of the inheritance of disease and disease risk. This concept has immense implications for the understanding of biological functions and disease etiology, and provides potential novel strategies for diagnosis and treatment. Examples of epigenetic inheritance relevant to human disease, such as the detrimental effects of traumatic stress or drug/toxic exposure on brain functions, are reviewed. Different possible routes of transmission of epigenetic information involving the germline or germline-independent transfer are discussed, and different mechanisms for the maintenance and transmission of epigenetic information like chromatin remodeling and small noncoding RNAs are considered. Future research directions and remaining major challenges in this field are also outlined. Finally, the adaptive value of epigenetic inheritance, and the cost and benefit of allowing acquired epigenetic marks to persist across generations is critically evaluated. PMID:22781843

  9. Genetics of proteasome diseases.

    The proteasome is a large, multiple subunit complex that is capable of degrading most intracellular proteins. Polymorphisms in proteasome subunits are associated with cardiovascular diseases, diabetes, neurological diseases, and cancer. One polymorphism in the proteasome gene PSMA6 (-8C/G) is associated with three different diseases: type 2 diabetes, myocardial infarction, and coronary artery disease. One type of proteasome, the immunoproteasome, which contains inducible catalytic subunits, is adapted to generate peptides for antigen presentation. It has recently been shown that mutations and polymorphisms in the immunoproteasome catalytic subunit PSMB8 are associated with several inflammatory and autoinflammatory diseases including Nakajo-Nishimura syndrome, CANDLE syndrome, and intestinal M. tuberculosis infection. This comprehensive review describes the disease-related polymorphisms in proteasome genes associated with human diseases and the physiological modulation of proteasome function by these polymorphisms. Given the large number of subunits and the central importance of the proteasome in human physiology as well as the fast pace of detection of proteasome polymorphisms associated with human diseases, it is likely that other polymorphisms in proteasome genes associated with diseases will be detected in the near future. While disease-associated polymorphisms are now readily discovered, the challenge will be to use this genetic information for clinical benefit. PMID:24490108

  11. Nonalcoholic fatty liver disease and cardiovascular disease.

    Nonalcoholic fatty liver disease (NAFLD) and cardiovascular disease (CVD) are two diseases that are common in the general population. To date, many studies have been conducted and demonstrate a direct link between NAFLD and CVD, but the exact mechanisms for this complex relationship are not well established. A systematic search of the PubMed database revealed that several common mechanisms are involved in many of the local and systemic manifestations of NAFLD and lead to an increased cardiovascular risk. The possible mechanisms linking NAFLD and CVD include inflammation, oxidative stress, insulin resistance, ectopic adipose tissue distribution, dyslipidemia, endothelial dysfunction, and adiponectin, among others. The clinical implication is that patients with NAFLD are at an increased risk of CVD and should undergo periodic cardiovascular risk assessment. PMID:25024598

    Prion diseases are rare in children. Three types are known: kuru, variant Creutzfeldt-Jakob disease (CJD), and iatrogenic CJD. All three affect children and young adults, and are transmitted by infectious contamination. Kuru was the result of ritual funeral practices similar to cannibalism; variant CJD affects young people who have eaten meat from cows with mad cow disease (mostly in the UK); and iatrogenic CJD is secondary to graft of human tissues performed in the 1980s (dura mater, pituitary extracted growth hormone). The disease appears after 4-30 years of incubation. The initial symptomatology is frequently neurological (cerebellar ataxia, oculomotor disturbance, peripheral nerve pain, pyramidal syndrome) followed by dementia. There is no biological test available that can give a definite diagnosis of prion disease apart from neuropathology, although prion accumulation in vCJD can be demonstrated in pharyngeal tonsil by immunohistochemical techniques. This devastating disease results inevitably in death. No specific treatment is available. PMID:23622328

    The blueback salmon fingerlings (Oncorhynchus nerka) at the U.S. Fish-Cultural Station at Winthrop, Washington, underwent an infection that was caused by a very short, Gram-positive, nonmotile, rod-shaped bacterium. A further description is impossible at this time, as the organism has not been grown satisfactorily for proper identification. The disease was characterized by white, raised areas of dead tissue mainly in the kidney: for this reason it is referred to as kidney disease. Belding and Merrill (1935) described a disease among the brook, brown, and rainbow trout at a State hatchery in Massachusetts which, from the description, might be the same as kidney disease. J.H. Wales of the California Division of Fish and Game described (unpublished manuscript, 1941) a disease in hatchery trout in California which seems to be identical to kidney disease.

    As the general population ages, the prevalence of Alzheimer's disease increases steadily. In France, 850,000 people are affected, with an annual incidence of 165,000 new cases. It is estimated that in 2020, 1.2 million people will be concerned in France. Nearly half of these patients, about 400,000, will have moderate to severe disease. These figures, issuing from the Eurodem group and the Paquid study, are estimates but clearly forecast an increase in upcoming years. While the disease generally affects elderly subjects, it is also known to occur early, before the age of 60. Nearly 20,000 patients will have an early onset form of the disease. Alzheimer's disease is first and foremost a brain disease, with lesions starting early in life. These early onset forms raise difficult diagnostic problems since these patients' problems are often mistakenly thought to arise from psychiatric disorders and treated as such in institutions inadapted to the patients' conditions.

    Viral infections induce multiple perturbations that spread along the links of the biological networks of the host cells. Understanding the impact of these cascading perturbations requires an exhaustive knowledge of the cellular machinery as well as a systems biology approach that reveals how individual components of the cellular system function together. Here we describe an integrative method that provides a new approach to studying virus-human interactions and its correlations with diseases. Our method involves the combined utilization of protein - protein interactions, protein -- DNA interactions, metabolomics and gene - disease associations to build a ``viraldiseasome''. By solely using high-throughput data, we map well-known viral associated diseases and predict new candidate viral diseases. We use microarray data of virus-infected tissues and patient medical history data to further test the implications of the viral diseasome. We apply this method to Epstein-Barr virus and Human Papillomavirus and shed light into molecular development of viral diseases and disease pathways.

    This editorial introduces the F1000Research rare disease collection. It is common knowledge that for new treatments to be successful there has to be a partnership between the many interested parties such as the patient, advocate, disease foundations, the academic scientists, venture funding organizations, biotech companies, pharmaceutical companies, NIH, and the FDA. Our intention is to provide a forum for discussion and dissemination of any rare disease related topics that will advance scientific understanding and progress to treatments. PMID:25580231
