Coexistence of chronic lymphocytic leukemia (CLL) with myelofibrosis is a rare association with only isolated case reports in the literature. We report an unusual case of CLL in which the cause of anemia was coexistent myelofibrosis. In a case of CLL presenting with refractory anemia, besides common causes like autoimmune hemolytic anemia and marrow infiltration, other causes like myelofibrosis should be searched for.

Primary myelofibrosis is a myeloproliferative neoplasm associated with significant morbidity and mortality, for which effective therapies are lacking. β-Arrestins are multifunctional adaptor proteins involved in developmental signaling pathways. One isoform, β-arrestin2 (βarr2), has been implicated in initiation and progression of chronic myeloid leukemia, another myeloproliferative neoplasm closely related to primary myelofibrosis. Accordingly, we investigated the relationship between βarr2 and primary myelofibrosis. In a murine model of MPLW515L-mutant primary myelofibrosis, mice transplanted with donor βarr2-knockout (βarr2-/-) hematopoietic stem cells infected with MPL-mutant retrovirus did not develop myelofibrosis, whereas controls uniformly succumbed to disease. Although transplanted βarr2-/- cells homed properly to marrow, they did not repopulate long-term due to increased apoptosis and decreased self-renewal of βarr2-/- cells. In order to assess the effect of acute loss of βarr2 in established primary myelofibrosis in vivo, we utilized a tamoxifen-induced Cre-conditional βarr2-knockout mouse. Mice that received Cre (+) donor cells and developed myelofibrosis had significantly improved survival compared with controls. These data indicate that lack of antiapoptotic βarr2 mediates marrow failure of murine hematopoietic stem cells overexpressing MPLW515L. They also indicate that βarr2 is necessary for progression of primary myelofibrosis, suggesting that it may serve as a novel therapeutic target in this disease.

To present the rare case of a young boy with idiopathic intracranial hypertension presenting with bilateral sensorineural hearing loss developing over several months. This was accompanied by headaches, otalgia, tinnitus, and vertigo. Furthermore, we aim to provide a concise review on this matter, as this report represents the second case in literature of pediatric idiopathic intracranial hypertension presenting with hearing loss. Workup of a 9-year-old boy with bilateral sensorineural hearing loss, including (among others) physical examination, audiometry, diagnostic imaging, and lumbar puncture. Physical examination including fundoscopy as well as imaging showed no abnormalities. At presentation, pure tone audiometry revealed bone conduction thresholds of about 30 dB HL in both ears. Two months later, this declined to about 35 dB HL in both ears. Lumbar puncture revealed an increased intracranial pressure. The boy was thus diagnosed with idiopathic intracranial hypertension. After the lumbar puncture, the otological complaints gradually resolved, and the hearing normalized (bone conduction thresholds of 0-5 dB HL). Although rare, sensorineural hearing loss in the pediatric population together with otalgia, tinnitus, and vertigo can be due to idiopathic intracranial hypertension and as such can be reversible. © The Author(s) 2015.

Full Text Available Abstract We studied non-driver mutations in 62 subjects with myeloproliferative neoplasm (MPN-associated myelofibrosis upon diagnosis, including 45 subjects with primary myelofibrosis (PMF and 17 with post-polycythemia vera or post-essential thrombocythemia myelofibrosis (post-PV/ET MF. Fifty-eight subjects had ≥1 non-driver mutation upon diagnosis. Mutations in mRNA splicing genes, especially in U2AF1, were significantly more frequent in PMF than in post-PV/ET MF (33 vs. 6%; P = 0.015. There were also striking differences in clonal architecture. These data indicate different genomic spectrums between PMF and post-PV/ET MF.

Primary myelofibrosis is characterized by clonal myeloproliferation, dysmegakaryopoiesis, extramedullary hematopoiesis associated with myelofibrosis and altered stroma in the bone marrow and spleen. The expression of CD9, a tetraspanin known to participate in megakaryopoiesis, platelet formation, cell migration and interaction with stroma, is deregulated in patients with primary myelofibrosis and is correlated with stage of myelofibrosis. We investigated whether CD9 participates in the dysmegakaryopoiesis observed in patients and whether it is involved in the altered interplay between megakaryocytes and stromal cells. We found that CD9 expression was modulated during megakaryocyte differentiation in primary myelofibrosis and that cell surface CD9 engagement by antibody ligation improved the dysmegakaryopoiesis by restoring the balance of MAPK and PI3K signaling. When co-cultured on bone marrow mesenchymal stromal cells from patients, megakaryocytes from patients with primary myelofibrosis displayed modified behaviors in terms of adhesion, cell survival and proliferation as compared to megakaryocytes from healthy donors. These modifications were reversed after antibody ligation of cell surface CD9, suggesting the participation of CD9 in the abnormal interplay between primary myelofibrosis megakaryocytes and stroma. Furthermore, silencing of CD9 reduced CXCL12 and CXCR4 expression in primary myelofibrosis megakaryocytes as well as their CXCL12-dependent migration. Collectively, our results indicate that CD9 plays a role in the dysmegakaryopoiesis that occurs in primary myelofibrosis and affects interactions between megakaryocytes and bone marrow stromal cells. These results strengthen the "bad seed in bad soil" hypothesis that we have previously proposed, in which alterations of reciprocal interactions between hematopoietic and stromal cells participate in the pathogenesis of primary myelofibrosis.

Development and growth of hematopoietic tissue outside of the bone marrow is termed extramedullary hematopoiesis (EMH). It occurs in patients with hematological diseases such as myelofibrosis and thalassemia. Liver and spleen are the usual sites of EMH. However, spinal cord compression caused by EMH is a rare complication. A 65-year-old man with myelofibrosis was admitted to our hospital with progressive paraparesis. Thoracic spine MRI revealed epidural masses causing cord compression. Histological examination of the epidural mass showed evidence of EMH consisting of megakaryocytic and erythroid hyperplasia. After surgical decompression and radiotherapy, lower limb weakness and sensory disturbance were significantly improved. MRI showed disappearance of the spinal cord compression. With this therapy, he had no recurrence until he died of myelofibrosis. Spinal EMH should be considered as a differential diagnosis in patients with hematological diseases presenting with paraparesis. Surgical decompression and radiotherapy are effective approaches for the treatment of paraparesis due to EMH.

Myelofibrosis and acquired hemophilia A is a rare association. To the best of our knowledge only one case of myelofibrosis and acquired hemophilia A has been previously described. A 66-year-old Caucasian man diagnosed with myelofibrosis evolving in acute myeloid leukemia was referred to us for postoperative bleeding. Hemostatic studies showed prolonged activated partial thromboplastin time, decreased factor VIII coagulation, and a high factor VIII inhibitor titer; these findings led to a diagnosis of acquired hemophilia A for which he was treated with methylprednisolone and recombinant activated factor VII on admission. Due to a lack of response he was subsequently treated with rituximab combined with activated prothrombin complex concentrates. Furthermore, he received azacytidine to treat the underlying hematological malignancies. Immunosuppressive rituximab therapy resolved acquired hemophilia A with marked efficacy. Rapid and accurate diagnosis, effective hemostatic therapy, and timely treatment for underlying disease are important in the management of acquired hemophilia A secondary to hematological malignancy.

Peritoneal carcinomatosis-like implants of extramedullary hematopoiesis. An insolite occurrence during splenectomy for myelofibrosis

Directory of Open Access Journals (Sweden)

Marco Casaccia

Full Text Available Introduction: Primary myelofibrosis (MF is a myeloproliferative neoplasm that results in debilitating constitutional symptoms, splenomegaly, and cytopenias. In patients with symptomatic splenomegaly, splenectomy remains a viable treatment option for MF patients with medically refractory symptomatic splenomegaly that precludes the use of ruxolitinib. Case presentation: We present the clinical case of a patient who was admitted to our Department to perform a splenectomy in MF as a therapeutic step prior to an allogeneic stem cell transplantation (ASCT. A laparotomic splenectomy and excision of whitish wide-spread peritoneal and omental nodulations was performed. There were no operative complications and the surgery was completed with minimal blood loss. The histopathological exam revealed an extramedullary hematopoiesis in both spleen and peritoneal nodules. Conclusion: In primary myelofibrosis it must always be kept in mind the possible presence of peritoneal implants of extramedullary hematopoiesis and ascites of reactive genesis. We report a rare case of peritoneal carcinomatosis-like implants of extramedullary hematopoiesis found at splenectomy for MF.

Full Text Available BACKGROUND: The detection of molecular and cytogenetic alterations is important for the diagnosis, prognosis and classification of myeloproliferative neoplasms. OBJECTIVE: The aim of this study was to detect the following mutations: JAK2 V617F, JAK2 exon 12 and MPL W515K/L, besides chromosomal abnormalities. Furthermore, molecular and cytogenetic alterations were correlated with the leukocyte and platelet counts, hemoglobin levels and age in all patients and with the degree of fibrosis in primary myelofibrosis cases. METHODS: Twenty cases of polycythemia vera, 17 of essential thrombocythemia and 21 of primary myelofibrosis were selected in the Hematology Department of the Universidade Federal de São Paulo (UNIFESP between February 2008 and December 2009. The JAK2 V617F, JAK2 exon 12 mutations, MPL W515K and MPL W515L mutations were investigated by real-time PCR and direct sequencing. G-band karyotyping and fluorescence in situ hybridization were used to detect chromosomal abnormalities. RESULTS: Chromosomal abnormalities were observed only in polycythemia vera (11.8% and primary myelofibrosis cases (17.6%, without correlation to clinical data. Chromosomal abnormalities were not detected by fluorescence in situ hybridization. The JAK2 V617F mutation was observed in polycythemia vera (90%, primary myelofibrosis (42.8% and essential thrombocythemia (47%. Patients with JAK2 V617F-negative polycythemia vera had lower platelet and leukocyte counts compared to V617F-positive polycythemia vera (p-value = 0.0001 and p-value = 0.023, respectively. JAK2 V617F-positive and MPL W515L-positive primary myelofibrosis cases had a higher degree of fibrosis than V617F-negative cases (p-value = 0.022. JAK2 exon 12 mutations were not detected in polycythemia vera patients. The MPL W515L mutation was observed in one case of primary myelofibrosis and in one of essential thrombocythemia.

Primary myelofibrosis is a chronic myeloproliferative neoplasm characterized by cytopenias, leukoerythroblastosis, extramedullary hematopoiesis, hepatosplenomegaly and bone marrow fibrosis. Primary myelofibrosis is a rare disorder in adults; children are even less commonly affected by this entity, with the largest pediatric case series reporting on three patients. Most literature suggests spontaneous resolution of myelofibrosis without long term complications in the majority of affected children. We describe the clinical, pathologic, and molecular characteristics and outcomes of nineteen children with primary myelofibrosis treated in our center from 1984 to 2011. Most patients had cytopenia significant enough to require supportive therapy. No child developed malignant transformation and only five of the 19 children (26%) had spontaneous resolution of disease. Sequence analyses for JAK2V617F and MPLW515L mutations were performed on bone marrow samples from 17 and six patients, respectively, and the results were negative. In conclusion, analysis of this large series of pediatric patients with primary myelofibrosis demonstrates distinct clinical, hematologic, bone marrow, and molecular features from adult patients.

Recent developments in myelofibrosis

Full Text Available Raoul Tibes, James M Bogenberger, Ruben A MesaDivision of Hematology and Oncology, Mayo Clinic, Scottsdale, AZ, USAAbstract: The myeloproliferative neoplasm of myelofibrosis (MF is clinically constituted by individuals both with primary MF, as well as those that evolved from an antecedent polycythemia vera or essential thrombocythemia. Individuals presenting with MF have a heterogeneous phenotype which can involve significant constitutional symptoms (night sweats, fevers, weight loss, fatigue, variable but frequently problematic splenomegaly, and multifactorial cytopenias. These individuals clearly have decreased survival. Refinement of MF prognostic scores can distinguish from survival as poor as 16 months, to a median survival of 185 months. Sadly, although curative, allogeneic stem cell transplant still has sobering success rates for individuals of the standard ages for MF. Recent reports suggest less than half of patients will be alive at 3 years after allotransplant above the age of 60 years. The most important recent advancement in MF therapy has been the development of Janus kinase 2 (JAK2 inhibitors led by ruxolitinib, now Food and Drug Administration approved in the United States, and several other JAK2 inhibitors (in testing including SAR302503, CYT387, and SB1518. In randomized, placebo-controlled studies, ruxolitinib was demonstrated to be superior for the improvement of splenomegaly and symptoms. These benefits are mirrored across other JAK2 inhibitors. Improving anemia remains an unmet need in MF and is currently being evaluated by clinical trials utilizing the JAK2 inhibitor CYT387, as well as pomalidomide. Additional areas of interest for MF therapy include the inhibition of histone/lysine deacetylases, hedgehog pathway inhibition, as well as combination strategies with JAK2 inhibitors.Keywords: myeloproliferative neoplasm, myelofibrosis, JAK2 inhibitors

BACKGROUND The V617F mutation, which causes the substitution of phenylalanine for valine at position 617 of the Janus kinase (JAK) 2 gene (JAK2), is often present in patients with polycythemia vera, essential thrombocythemia, and idiopathic myelofibrosis. However, the molecular basis of these myeloproliferative disorders in patients without the V617F mutation is unclear. METHODS We searched for new mutations in members of the JAK and signal transducer and activator of transcription (STAT) gene families in patients with V617F-negative polycythemia vera or idiopathic erythrocytosis. The mutations were characterized biochemically and in a murine model of bone marrow transplantation. RESULTS We identified four somatic gain-of-function mutations affecting JAK2 exon 12 in 10 V617F-negative patients. Those with a JAK2 exon 12 mutation presented with an isolated erythrocytosis and distinctive bone marrow morphology, and several also had reduced serum erythropoietin levels. Erythroid colonies could be grown from their blood samples in the absence of exogenous erythropoietin. All such erythroid colonies were heterozygous for the mutation, whereas colonies homozygous for the mutation occur in most patients with V617F-positive polycythemia vera. BaF3 cells expressing the murine erythropoietin receptor and also carrying exon 12 mutations could proliferate without added interleukin-3. They also exhibited increased phosphorylation of JAK2 and extracellular regulated kinase 1 and 2, as compared with cells transduced by wild-type JAK2 or V617F JAK2. Three of the exon 12 mutations included a substitution of leucine for lysine at position 539 of JAK2. This mutation resulted in a myeloproliferative phenotype, including erythrocytosis, in a murine model of retroviral bone marrow transplantation. CONCLUSIONS JAK2 exon 12 mutations define a distinctive myeloproliferative syndrome that affects patients who currently receive a diagnosis of polycythemia vera or idiopathic erythrocytosis

Ruxolitinib is a potent Janus kinase (JAK) 1/JAK2 inhibitor that has demonstrated rapid and durable improvements in splenomegaly and symptoms and a survival benefit in 2 phase 3 trials in patients with myelofibrosis. Ruxolitinib was well tolerated and effectively reduced splenomegaly and symptom burden in Asian patients with myelofibrosis in the Asian multinational, phase 2 Study A2202. We present a subset analysis of Japanese patients (n = 30) in Study A2202. At data cutoff, 22 patients were ongoing; 8 discontinued, mainly due to adverse events (n = 4). At week 24, 33 % of patients achieved ≥35 % reduction from baseline in spleen volume; 56.0 % achieved ≥50 % reduction from baseline in total symptom score, as measured by the 7-day Myelofibrosis Symptom Assessment Form v2.0. The most common adverse events were anemia (63 %), thrombocytopenia (40 %), nasopharyngitis (37 %), decreased platelet counts (30 %), and diarrhea (30 %). Dose reductions or interruptions due to hemoglobin decreases were more frequent in Japanese patients; no loss of efficacy and no discontinuations due to hematologic abnormalities were observed. Ruxolitinib was well tolerated in Japanese patients and provided substantial reductions in splenomegaly and myelofibrosis-related symptoms similar to those observed in the overall Asian population and phase 3 COMFORT studies.

Addison's disease presenting with idiopathic intracranial hypertension in 24-year-old woman: a case report

Directory of Open Access Journals (Sweden)

Moore Peter

2010-02-01

Full Text Available Abstract Introduction Idiopathic intracranial hypertension can rarely be associated with an underlying endocrine disorder such as Cushing's syndrome, hyperthyroidism, or with administration of thyroxine or growth hormone. Though cases of idiopathic intracranial hypertension associated with Addison's disease in children have been reported, there is only one documented case report of this association in adults. We describe a case of an acute adrenal insufficiency precipitated by idiopathic intracranial hypertension in a Caucasian female. Case presentation A 24-year-old Caucasian woman was acutely unwell with a background of several months of generalised fatigue and intermittent headaches. She had unremarkable neurological and systemic examination with a normal computerised tomography and magnetic resonance imaging of the brain. Normal cerebrospinal fluid but increased opening pressure at lumbar puncture suggested intracranial hypertension. A flat short synacthen test and raised level of adrenocorticotrophic hormone were consistent with primary adrenal failure. Conclusion Addison's disease can remain unrecognised until precipitated by acute stress. This case suggests that idiopathic intracranial hypertension can rarely be associated with Addison's disease and present as an acute illness. Idiopathic intracranial hypertension is possibly related to an increase in the levels of arginine vasopressin peptide in serum and cerebrospinal fluid secondary to a glucocorticoid deficient state.

Objective was to describe the clinical features of 5 patients with rare atypical presentation of idiopathic intracranial hypertension (IIH), and propose the possible mechanism of this atypical presentation. We carried out a retrospective study of 5 patients, admitted at King Khalid National Guard Hospital, Jeddah, Kingdom of Saudi Arabia with IIH during the period from January 2001 to December 2005. All were females with their age ranges from 24 to 40 years. The clinical presentations, the laboratory and imaging studies were analyzed. The opening pressures of the lumbar puncture tests were documented. All patients were presented with headache. One had typical pain of trigeminal neuralgia and one with neck pain and radiculopathy. Facial diplegia was present in one patient and two patients had bilateral 6th cranial neuropathy. Papilledema was present in all patients except in one patient. Imaging study was normal in all patients, and they had a very high opening pressure during lumbar puncture, except in one patient. All patients achieved full recovery with medical therapy in 6 to 12 weeks with no relapse during the mean follow up of 2 years. Atypical finding in IIH are rare and require a high index of suspicion for early diagnosis. (author)

Bone marrow scintigraphy. An aid to the diagnosis and prognosis of myelofibrosis

International Nuclear Information System (INIS)

Rain, J.D.; Najean, Y.

1993-01-01

During the last three years 77 patients with myelofibrosis were studied by scintigraphy, using 99m Tc colloids and 111 in transferring as tracers. Low axial uptake of the colloids, extension of the indium uptake beyond the axis towards the knees and sometimes the ankles and elbows, and splenic indium uptake are valuable diagnostic criteria, particularly useful to exclude myelofibrosis associated with a malignant disorder. The clinical severity of the disease, and in particular the disappearance of physiologically active bone marrow (indium uptake) can be predicted from isotopic studies. Bone marrow scintigraphy could contribute to the difficult decision of splenectomy

MF is characterized by bone marrow fibrosis, splenomegaly, leukoerythroblastosis, extramedullary hematopoiesis, and a collection of debilitating symptoms. Until recently, the therapeutic options for patients with MF consisted of allogeneic hematopoietic stem cell transplant (alloHSCT, the use of cytoreductive agents (ie, hydroxyurea, splenectomy and splenic irradiation for treatment of splenomegaly, and management of anemia with transfusions, erythropoiesis-stimulating agents (ESAs, androgens, and immunomodulatory agents. However, with increased understanding of the pathogenesis of MF resulting from dysregulated Janus kinase (JAK signaling, new targeted JAK inhibitor therapies, such as ruxolitinib, are now available. The purpose of this article is to review the clinical features of MF, discuss the use and future of JAK inhibitors, reassess when and how to use conventional MF treatments in the context of JAK inhibitors, and provide a perspective on the future of MF treatment.Keywords: myelofibrosis, ruxolitinib, JAK inhibitor

Myelofibrosis is the rarest and most severe type of Philadelphia-negative classical myeloproliferative neoplasms. Although mutually exclusive driver mutations in JAK2, MPL, or CALR that activate JAK-STAT pathway have been related to the pathogenesis of the disease, chromosome abnormalities have also been associated with the phenotype and prognosis of the disease. Here, we report the use of a chromosomal microarray platform consisting of both oligo and SNP probes to improve the detection of chromosome abnormalities in patients with myelofibrosis. Sixteen patients with myelofibrosis were tested, and the results were compared to karyotype analysis. Driver mutations in JAK2, MPL, or CALR were investigated by PCR and MLPA. Conventional cytogenetics revealed chromosome abnormalities in 3 out of 16 cases (18.7%), while chromosomal microarray analysis detected copy-number variations (CNV) or copy-neutral loss of heterozygosity (CN-LOH) alterations in 11 out of 16 (68.7%) patients. These included 43 CN-LOH, 14 deletions, 1 trisomy, and 1 duplication. Ten patients showed multiple chromosomal abnormalities, varying from 2 to 13 CNVs or CN-LOHs. Mutational status for JAK2, CALR, and MPL by MLPA revealed a total of 3/16 (18.7%) patients positive for the JAK2 V617F mutation, 9 with CALR deletion or insertion and 1 positive for MPL mutation. Considering that most of the CNVs identified were smaller than the karyotype resolution and the high frequency of CN-LOHs in our study, we propose that chromosomal microarray platforms that combine oligos and SNP should be used as a first-tier genetic test in patients with myelofibrosis. © 2018 S.

Full Text Available Blood cytopenia represents one of the diagnostic criteria for systemic lupus erythematosus (SLE and may occur as the first symptom of the disease. Antibody-mediated peripheral destruction of blood cells is the main cause of cytopenia observed in patients affected by SLE, however, inflammatory anemia, nutritional deficiencies, immunosuppressive therapy and, more rarely, myelofibrosis (MF have also been documented. In the literature, 45 cases of autoimmune MF (AIMF and SLE have been previously reported. Here the 46th case of a 43-year-old female with a SLE and an underhand cytopenia, with a review of the literature. Keywords: Systemic lupus erythematosus, Autoimmune myelofibrosis, Blood cytopenia

Myelofibrosis (MF) is a bone marrow disorder characterized by clonal myeloproliferation, aberrant cytokine production, extramedullary hematopoiesis, and bone marrow fibrosis. Although somatic mutations in JAK2, MPL, and CALR have been identified in the pathogenesis of these diseases, inhibitors of the Jak2 pathway have not demonstrated efficacy in ameliorating MF in patients. TGF-? family members are profibrotic cytokines and we observed significant TGF-?1 isoform overexpression in a large co...

Although spondylolysis is found in 6% of idiopathic scoliosis patients, very little was reported on management of pars defects in this group. These patients with painful spondylolysis are most eligible for direct repair of the defect rather than lumbosacral fusion in an attempt to save motion segments. The aim of this work was to analyze the clinical and radiologic outcome of pars repair in a group of adolescents who presented after surgical correction of their idiopathic scoliosis. A prospective nonrandomized study. Ten consecutive patients with spondylolysis presenting after an average of 3 months (range, 2-7 months) from correction of their idiopathic scoliosis with low back pain not responding to conservative therapy and interfering with everyday activities. The mean age at operation was 16 years (range, 14-19 years). Total blood loss, operative time, and hospital stay were recorded. Clinical outcome was assessed by the Oswestry Disability Index (ODI), visual analog scale (VAS), and Scoliosis Research Society (SRS)-22 questionnaire. Fusion of the pars interarticularis was assessed using plain, lateral, and oblique radiographs and a computed tomography (CT) scan. The surgical technique consisted of thorough debridement of the defect, impacting the gap created with a tricortical iliac crest graft, and rigid fixation by either pedicle screws and a V-shaped rod (five patients) or a cable-screw construct (five patients). Patients were followed up for an average of 4.5 years (range, 2-7 years). Nine patients had a good-to-excellent result, returned to normal everyday life, and participated in sports when desired. The mean ODI, VAS, and SRS total scores were 11 (range, 0-34), 1.1 (range, 0-2), and 92 (range, 61-108), respectively. Follow-up radiographs and CT scans revealed healing of all defects in nine cases, no signs of disc degeneration in any, and no implant-related complications. The results of direct repair of spondylolysis in idiopathic scoliosis patients were

Full Text Available Castleman disease (CD describes a group of three rare and poorly understood lymphoproliferative disorders that have heterogeneous clinical symptoms and common lymph node histopathological features. Unicentric CD (UCD involves a single region of enlarged nodes. Multicentric CD (MCD involves multiple regions of enlarged lymph nodes, constitutional symptoms, and organ dysfunction due to a cytokine storm often including interleukin 6. MCD is further divided into Human Herpes Virus-8 (HHV-8-associated MCD, which occurs in immunocompromised individuals, and HHV-8-negative/idiopathic MCD (iMCD. Recently, iMCD has been further sub-divided into patients with TAFRO syndrome, which involves thrombocytopenia (T, anasarca (A, fevers (F, reticulin myelofibrosis (R, organomegaly (O, and normal or only slightly elevated immunoglobulin levels, and those who do not have TAFRO syndrome. Non-TAFRO iMCD patients typically have thrombocytosis, less severe fluid accumulation, and hypergammaglobulinemia. iMCD patients with TAFRO syndrome may have a worse prognosis, but more research is needed.

The spleen tyrosine kinase (SYK) was identified as an oncogenic driver in a broad spectrum of hematologic malignancies. The in vivo comparison of three SYK containing oncogenes, SYK wt , TEL–SYK and IL-2-inducible T-cell kinase (ITK)-SYK revealed a general myeloexpansion and the establishment of three different hematologic (pre)diseases. SYK wt enhanced the myeloid and T-cell compartment, without leukemia/lymphoma development. ITK–SYK caused lethal T-cell lymphomas and the cytoplasmic TEL–SYK fusion induced an acute panmyelosis with myelofibrosis-type acute myeloid leukemia (AML) with up to 50% immature megakaryoblasts infiltrating bone marrow, spleen and liver, additional MPN features (myelofibrosis and granulocyte expansion) and MDS stigmata with megakaryocytic and erythroid dysplasia. LKS cells were reduced and all subsets (LT/ST/MPP) showed reduced proliferation rates. SYK inhibitor treatment (R788) of diseased TEL–SYK mice reduced leukocytosis, spleen and liver infiltration, enhanced the hematocrit and prolonged survival time, but could not significantly reduce myelofibrosis. Stat5 was identified as a major downstream mediator of TEL–SYK in vitro as well as in vivo. Consequently, targeted deletion of Stat5 in vivo completely abrogated TEL–SYK-induced AML and myelofibrosis development, proving Stat5 as a major driver of SYK-induced transformation. Our experiments highlight the important role of SYK in AML and myelofibrosis and prove SYK and STAT5 inhibitors as potent treatment options for those diseases

Full Text Available One case of acute panmyelosis with myelofibrosis (APMF is being reported. A 45 year old male presented with abrupt onset of rapidly progressing low backache, weakness and pancytopenia. On examination there was no organomegaly. Peripheral blood examination revealed normocytic normochromic red blood cells with 10% circulating blasts. Flowcytometric examination of peripheral blood revealed blasts which were positive for CD 34 ,HLA- DR and myeloid associated antigens (i.e. CD13 and CD33.Blasts were negative for anti MPO. Bone marrow aspirate resulted in a dry tap. Bone marrow biopsy revealed panmyeloid proliferation with scattered blasts which were CD 34 positive on imunohistochemistry and negative for anti MPO. Reticulin stain showed grade III myelofibrosis (WHO. Differential diagnosis considered included AML-M7, MDS-RAEB II and AML with myelodysplasia . He was started on chemotherapy [idarubicin and cytarabine; 3+7 induction regimen followed by three cycles of HIDAC (High dose cytosine arabinoside] after which patient was in complete morphological remission with markedly reduced bone marrow fibrosis. He is now being worked up for allogeneic stem cell transplantation. Patient is asymptomatic at eight months of diagnosis. In conclusion these patients should be managed aggressively with AML therapy and this case report reaffirms the fact that APMF is subtype of AML.

Bausà, Roser; Navarro, Lydia; Cortès-Franch, Imma

Long-term exposure to benzene has been associated with several blood malignancies, including aplastic anemia, myeloproliferative neoplasms, and different leukemias. We present a case of primary myelofibrosis in a 59-year-old woman who worked as a cleaner at a car dealership and automobile mechanic shop. For 25 years, she used gasoline as a degreaser and solvent to clean engine parts, floors and work desks on a daily basis. She was referred by her primary care provider to the Occupational Health Unit of Barcelona to assess whether her illness was work-related. Review of her job history and working conditions revealed chronic exposure to benzene in the absence of adequate preventive measures. An association between benzene exposure and myeloproliferative disease was established, suspicious for an occupational disease. Copyright belongs to the Societat Catalana de Salut Laboral.

Primary myelofibrosis (MF) is a myeloproliferative neoplasm that results in debilitating constitutional symptoms, splenomegaly, and cytopenias. In patients with symptomatic splenomegaly, splenectomy remains a viable treatment option for MF patients with medically refractory symptomatic splenomegaly that precludes the use of ruxolitinib. We present the clinical case of a patient who was admitted to our Department to perform a splenectomy in MF as a therapeutic step prior to an allogeneic stem cell transplantation (ASCT). A laparotomic splenectomy and excision of whitish wide-spread peritoneal and omental nodulations was performed. There were no operative complications and the surgery was completed with minimal blood loss. The histopathological exam revealed an extramedullary hematopoiesis in both spleen and peritoneal nodules. In primary myelofibrosis it must always be kept in mind the possible presence of peritoneal implants of extramedullary hematopoiesis and ascites of reactive genesis. We report a rare case of peritoneal carcinomatosis-like implants of extramedullary hematopoiesis found at splenectomy for MF. Copyright © 2017 The Authors. Published by Elsevier Ltd..

Noonan syndrome is a heterogenous rasopathy typically presenting with short stature, characteristic facial features, cardiac abnormalities including pulmonic valve stenosis, ASD and hypertrophic cardiomyopathy (HCM), cryptorchidism, ectodermal abnormalities, and learning differences. The phenotype is variable, and limited genotype phenotype correlation exists with SOS1 mutations often associated with normal cognition and stature, RAF1 mutations entailing a high HCM risk, and certain PTPN11 mutations predisposing to juvenile myelomonocytic leukemia. The recently identified SHOC2 mutation (p.Ser2Gly) causes Noonan syndrome with loose anagen hair. We report five patients with this mutation. All had skin hyperpigmentation, sparse light colored hair, increased fine wrinkles, ligamentous laxity, developmental delay, and 4/4 had a structural cardiac anomaly. Hypotonia and macrocephaly occurred in 4/5 (80%); 3/5 (60%) had polyhydramnios, increased birth weight or required use of a feeding tube. Distinctive brain abnormalities included relative megalencephaly and enlarged subarachnoid spaces suggestive of benign external hydrocephalus, and a relatively small posterior fossa as indicated by a vertical tentorium. The combination of a large brain with a small posterior fossa likely resulted in the high rate of cerebellar tonsillar ectopia (3/4; 75%). Periventricular nodular heterotopia was seen in one patient with a thick and dysplastic corpus callosum. We report on the first hematologic neoplasm, myelofibrosis, in a 2-year-old patient with SHOC2 mutation. Myelofibrosis is exceedingly rare in children and young adults. The absence of a somatic JAK2 mutation, seen in the majority of patients with myelofibrosis, is noteworthy as it suggests that germline or somatic SHOC2 mutations are causally involved in myelofibrosis.

Bone and bone-marrow blood flow in chronic granulocytic leukemia and primary myelofibrosis

International Nuclear Information System (INIS)

Lahtinen, R.; Lahtinen, T.; Romppanen, T.

1982-01-01

Blood flow in hematopoietic bone marrow and in nonhematopoietic bone has been measured with a Xe-133 washout method in 20 patients with chronic granulocytic leukemia (CGL) and in seven with primary myelofibrosis. Age-matched healthy persons served as controls. Bone-marrow blood flow in CGL was dependent upon the phase of the disease. In the metamorphosis phase, bone-marrow blood flow was high compared with that in the well-controlled phase. Apart from the initial phase, the mean values for bone blood flow in CGL were increased compared with the values of the healthy controls. In myelofibrosis the bone blood flow was also increased. Bone-marrow blood flow in these diseases was dependent upon the cellularity of bone marrow as measured morphometrically

Atypical presentation of acute idiopathic megacolon in a 14-year-old patient

Full Text Available In clinical practice the term “megacolon” is used to indicate a marked dilatation of the cecum and the sigmoid colon (>12 and 6.5 cm, respectively (1. From a clinical standpoint, a megacolon can be classified as chronic or acute depending on its clinical presentation. Chronic megacolon typically refers to a congenital disorder in which the enteric nervous system (ENS supplying the colon does not develop properly, thereby leaving the distal segments of the viscus without myenteric and submucosal ganglia (i.e. Hirschsprung’s disease (2. Other cases of non-aganglionic chronic megacolon can be secondary to variety of conditions such as Chagas’ disease and neurodegenerative diseases (e.g. Parkinson’s and Alzheimer’s diseases, leading to or associated with ENS abnormalities (3. The acute form of megacolon, also referred to as Ogilvie’s syndrome, is characterized by a predominant involvement of the cecum and right colon usually affecting elderly patients undergoing surgery (e.g. orthopedic procedures or taking medications altering gut motility (e.g. opioids or antidepressants (4. Some forms of acute megacolon, however, can be idiopathic in origin since no underlying etiology can be identified. Patients with acute idiopathic megacolon usually have a longstanding history of constipation, often accompanied by laxative abuse, and their clinical presentation is characterized by abdominal distension and severe pain with radiological evidence of stool impacted in the colon and rectum (1, 4. The case herein reported represents an unusual form of acute idiopathic megacolon characterized by massive descending and sigmoid colon distension complicated with a volvulus in a 14-year-old boy with no Hirschsprung’s disease. In addition, just to increase the peculiarity of this case report, the patient had an unremarkable clinical record, and never suffered from chronic constipation in the past.

Ruxolitinib, a JAK1/JAK2 tyrosine kinase inhibitor, is now widely used for first- and second-line therapy in persons with MPN-MF, especially those with disease-related splenomegaly, intermediate- or high-risk disease, and constitutional symptoms. The goal of this work is to critically analyze data supporting use of ruxolitinib in the clinical settings approved by the US Food and Drug Administration (FDA and European Medicines Agency (EMA. We systematically reviewed the literature and analyzed the risk of biases in the two randomized studies (COMFORT I and COMFORT II on which FDA and EMA approval was based. Our strategy was to apply the Grading of Recommendation, Assessment, Development and Evaluation (GRADE approach by evaluating five dimensions of evidence: (1 overall risk of bias, (2 imprecision, (3 inconsistency, (4 indirectness, and (5 publication bias. Based on these criteria, we downgraded the evidence from the COMFORT I and COMFORT II trials for performance, attrition, and publication bias. In the disease-associated splenomegaly sphere, we upgraded the quality of evidence because of large effect size but downgraded it because of comparator choice and outcome indirectness (quality of evidence, low. In the sphere of treating persons with intermediate- or high-risk disease, we downgraded the evidence because of imprecision in effect size measurement and population indirectness. In the sphere of disease-associated symptoms, we upgraded the evidence because of the large effect size, but downgraded it

Idiopathic ophthalmodynia and idiopathic rhinalgia were described a few years ago. These conditions seem specific pain syndromes with a distinctive location in the eye or in the nose. We aimed to present a new prospective series in order to verify the consistency of these syndromes. We performed a descriptive study of all patients referred to our regional neurologic clinics from 2010 to 2014 because of facial pain exclusively felt in the eye or in the nose fulfilling the proposed diagnostic criteria for idiopathic ophthalmodynia and idiopathic rhinalgia. There were 9 patients with idiopathic ophthalmodynia and 7 patients with idiopathic rhinalgia, with a clear female preponderance, and a mean age at onset in the fifth decade. The pain was usually moderate and the temporal pattern was generally chronic. Only one patient reported accompaniments (hypersensitivity to the light and to the flow of air in the symptomatic eye). Preventive treatment with amitriptyline, pregabalin, or gabapentin was partially or totally effective. The clinical features of this new series parallels those of the original description, thus indicating that both idiopathic ophthalmodynia and idiopathic rhinalgia have clear-cut clinical pictures with excellent consistency both inter- and intra-individually. © 2015 American Headache Society.

Splenic irradiation in myelofibrosis. Clinical findings and ferrokinetics

Nine patients were submitted to splenic or, in two cases, hepatosplenic irradiation; these patients presented a primary myelofibrosis or a spent polycythemia vera characterized by splenomegaly, anemia, and occasionally leucocytosis and thrombocytopenia. The hematological condition returned to normal in 2 patients. This improvement lasted 4 years after a first series of irradiation. The recurrence of splenomegaly and anemia indicated a second series of irradiation, the results of which were as good as those of the first series. Ineffective medullary and splenic erythropoiesis without preeminent aplasia appeared to be correlated with a beneficial effect of splenic irradiation. Absence of hepatomegaly and marked leucocytosis were less important prognostic factors. The modee of action of radiotherapy and the way in which it differs from splenectomy are discussed. The irradiation delivered moderate doses (450 rad in 18 sessions of 25 rad). Hepatic irradiation did not appear to be essential even in cases of intense hepatic myeloid metaplasia: in 2 patients liver erythropoiesis regressed when the spleen alone was irradiated

Four cases of idiopathic chondrolysis of the hip in three white girls and one Maori girl are reported. The authors stress the causes why a disease with characteristic clinical and radiographic appearances and normal biochemical findings presents diagnostic difficulties. It is suspected that idiopathic chondrolysis is a metabolic disorder of chondrocytes, triggered by environment circumstances in susceptible individuals. Idiopathic chondrolysis is probably one of the most common causes of coxarthrosis in women. (orig.)

Successful Control of Acute Myelofibrosis with Lenalidomide

2010-01-01

Full Text Available Acute panmyelosis with myelofibrosis (APMF is a rare, fatal hematological neoplasm that is characterized by the acute onset of cytopenias and fibrosis in the bone marrow in the absence of splenomegaly or fibrosis-related morphological changes in the RBCs. We present the case of a 59-year-old female who presented with a two-month history of anemia, leucopenia and a normal platelet count. The marrow was heavily fibrotic, and no aspirate material could be obtained; the biopsy showed extensive infiltration with small to medium size megakaryocytes, dysplastic changes in the erythroid compartment, and left shift in the myeloid cells. The patient was treated for four months with anabolic steroids (Danazol, growth factors and received regular blood transfusions. At 4 months after diagnosis, the patient was started on Lenalidomide, 10 mg/day for a 21-d-course along with growth factor support. At 6 months after treatment, the patient was transfusion-independent, had normalized blood counts, and, at 32 months on continuous lenalidomide treatment, her needs for growth factor support have been minimized. Repeat bone marrow biopsies showed a patchy distribution of fibrosis with areas of normal cellularity and morphology. To our knowledge, this is the first case for a medication that could reverse the fatal outcome of APMF.

Previous data established that plitidepsin, a cyclic depsipeptide, exerted activity in a mouse model of myelofibrosis (MF). New preclinical experiments reported herein found that low nanomolar plitidepsin concentrations potently inhibited the proliferation of JAK2V617F-mutated cell lines and reduced colony formation by CD34+ cells of individuals with MF, at least in part through modulation of p27 levels. Cells of MF patients had significantly reduced p27 content, that were modestly increased upon plitidepsin exposure. On these premise, an exploratory phase II trial evaluated plitidepsin 5 mg/m 2 3-h intravenous infusion administered on days 1 and 15 every 4 weeks (q4wk). Response rate (RR) according to the International Working Group for Myelofibrosis Research and Treatment consensus criteria was 9.1% (95% CI, 0.2–41.3%) in 11 evaluable patients during the first trial stage. The single responder achieved a red cell transfusion independence and stable disease was reported in nine additional patients (81.8%). Eight patients underwent a short-lasting improvement of splenomegaly. In conclusion, plitidepsin 5 mg/m 2 3-h infusion q4wk was well tolerated but had a modest activity in patients with primary, post-polycythaemia vera or post-essential thrombocythaemia MF. Therefore, this trial was prematurely terminated and we concluded that further clinical trials with plitidepsin as single agent in MF are not warranted

Fanconi's syndrome is a complex of multiple tubular dysfunctions of proximal tubular cells occurring alone or in association with a variety of inherited (primary) or acquired (secondary) disorders. It is characterized by aminoaciduria, normoglycaemic glycosuria, tubular proteinuria without hematuria, metabolic acidosis without anion gap and excessive urinary excretion of phosphorous, calcium, uric acid, bicarbonate, sodium, potassium, and magnesium. Whereas diabetes insipidus is a disease of collecting tubules and child mainly presents with dehydration and hypernatremia. Though all the cases published till date were secondary to drugs, myeloma, hematological disorders, etc., we are reporting the first case of idiopathic Fanconi's syndrome along with nephrogenic diabetes insipidus in a child who presented to us as resistant rickets. Medline search did not reveal any case of nephrogenic diabetes insipidus associated with idiopathic Fanconi syndrome. We hypothesized that the NDI may be due to of severe hypokalemia induced tubular dysfunction.

Full Text Available A 60-year-old white male patient was admitted to the hospital with acute abdominal pain, seemingly a self-limited ileus. He was found to be hepatitis B surface antigen (HBsAg-positive. Previous dental treatment was suspected to be the initial source of the infection with hepatitis B virus. Five months later he was re-admitted with a diagnosis of adrenal insufficiency (Addison’s disease which responded well to steroids. Four years later he developed fever and leucocytosis. A bone marrow biopsy revealed myelofibrosis. He had several episodes of pyrexia during his lifetime. After a 12-year period the patient suffered a fatal myocardial infarction. At autopsy the adrenal glands were reduced to scarred remnants and HBsAg was found to be present in the residual adrenocortical cells by immunoflouresence methods. Bone marrow at autopsy revealed myelosclerosis as well HBsAg (via immunofluoresence. Hepatitis B virus was therefore closely correlated with the development of Addison’s disease and myelofibrosis in this case.

Recent advances in understanding myelofibrosis and essential thrombocythemia [version 1; referees: 2 approved

Full Text Available The classic BCR-ABL-negative myeloproliferative neoplasms (MPNs, a form of chronic malignant hemopathies, have been classified into polycythemia vera (PV, essential thrombocythemia (ET, and primary myelofibrosis (PMF. ET and PMF are two similar disorders in their pathogenesis, which is marked by a key role of the megakaryocyte (MK lineage. Whereas ET is characterized by MK proliferation, PMF is also associated with aberrant MK differentiation (myelodysplasia, leading to the release of cytokines in the marrow environment, which causes the development of myelofibrosis. Thus, PMF is associated with both myeloproliferation and different levels of myelodysplastic features. MPNs are mostly driven by mutated genes called MPN drivers, which abnormally activate the cytokine receptor/JAK2 pathway and their downstream effectors. The recent discovery of CALR mutations has closed a gap in our knowledge and has shown that this mutated endoplasmic reticulum chaperone activates the thrombopoietin receptor MPL and JAK2. These genetic studies have shown that there are two main types of MPNs: JAK2V617F-MPNs, including ET, PV, and PMF, and the MPL-/CALR-MPNs, which include only ET and PMF. These MPN driver mutations are associated with additional mutations in genes involved in epigenetics, splicing, and signaling, which can precede or follow the acquisition of MPN driver mutations. They are involved in clonal expansion or phenotypic changes or both, leading to myelofibrosis or leukemic transformation or both. Only a few patients with ET exhibit mutations in non-MPN drivers, whereas the great majority of patients with PMF harbor one or several mutations in these genes. However, the entire pathogenesis of ET and PMF may also depend on other factors, such as the patient’s constitutional genetics, the bone marrow microenvironment, the inflammatory response, and age. Recent advances allowed a better stratification of these diseases and new therapeutic approaches with

To describe 2 topographic facial pain conditions with the pain clearly localized in the eye (idiopathic ophthalmodynia) or in the nose (idiopathic rhinalgia), and to propose their distinction from persistent idiopathic facial pain. Persistent idiopathic facial pain, burning mouth syndrome, atypical odontalgia, and facial arthromyalgia are idiopathic facial pain syndromes that have been separated according to topographical criteria. Still, some other facial pain syndromes might have been veiled under the broad term of persistent idiopathic facial pain. Through a 10-year period we have studied all patients referred to our neurological clinic because of facial pain of unknown etiology that might deviate from all well-characterized facial pain syndromes. In a group of patients we have identified 2 consistent clinical pictures with pain precisely located either in the eye (n=11) or in the nose (n=7). Clinical features resembled those of other localized idiopathic facial syndromes, the key differences relying on the topographic distribution of the pain. Both idiopathic ophthalmodynia and idiopathic rhinalgia seem specific pain syndromes with a distinctive location, and may deserve a nosologic status just as other focal pain syndromes of the face. Whether all such focal syndromes are topographic variants of persistent idiopathic facial pain or independent disorders remains a controversial issue.

Idiopathic ventricular tachycardia and fibrillation.

Belhassen, B; Viskin, S

1993-06-01

Important data have recently been added to our understanding of sustained ventricular tachyarrhythmias occurring in the absence of demonstrable heart disease. Idiopathic ventricular tachycardia (VT) is usually of monomorphic configuration and can be classified according to its site of origin as either right monomorphic (70% of all idiopathic VTs) or left monomorphic VT. Several physiopathological types of monomorphic VT can be presently individualized, according to their mode of presentation, their relationship to adrenergic stress, or their response to various drugs. The long-term prognosis is usually good. Idiopathic polymorphic VT is a much rarer type of arrhythmia with a less favorable prognosis. Idiopathic ventricular fibrillation may represent an underestimated cause of sudden cardiac death in ostensibly healty patients. A high incidence of inducibility of sustained polymorphic VT with programmed ventricular stimulation has been found by our group, but not by others. Long-term prognosis on Class IA antiarrhythmic medications that are highly effective at electrophysiologic study appears excellent.

The thrombopoietin receptor gene (MPL) is expressed in megakaryocytes and exhibits the gain of function point mutation W515K/L in approximately 5% of patients with primary myelofibrosis/idiopathic myelofibrosis (PMF) representing one subtype of the chronic myeloproliferative disorders (myeloproliferative neoplasm). A series of primary and secondary acute myeloid leukaemias (AML) with megakaryoblastic phenotype and myelofibrosis unrelated to PMF (n=12) was analysed for the MPL(W515K/L) mutation by pyrosequencing. In three cases (25%), MPL(W515L) was found and in two of these a combination with trisomy 21 or the Philadelphia chromosome occurred. None of the secondary AML cases evolving from pre-existing PMF showed MPL(W515K/L) (n=4). We conclude that MPL(W515L) occurs in a considerable proportion of acute megakaryoblastic leukaemias with myelofibrosis unrelated to PMF.

To determine the clinical characteristic, clinical presentations and radiological features of diopathic granulomatous mastitis, and the best treatment approaches of this clinical entity. Between 1996 and 2003 the files and histopathology reports of 25 patients with granulomatous mastitis at King Abdul-Aziz University Hospital Jeddah, Kindom of Saudi Arabia were reviewed. The data were analyzed and a Medline search was carried out from 1970 to 2003 to review relevant cases. The age of patients ranged from 24-66 years and the mean age was 36.6+-9.43 years. All patients were females. The most common clinical presentation was palpable tender mass. The most common mammographic finding was ill-defined mass. However, mixed hypo- and hyper-echogenic lesions with tubular connections were the common ultrasonic findings. Treatment approaches were conservative or surgical excision or steroid. Conservative treatment associated with the higher rate of complications, while treatment with steroid showed complete remission of disease. Idiopathic granulomatous mastitis is a rare, benign breast disease that is usually underestimated or misdiagnosed. The clinical and radiological features resemble those of infectious mastitis or breast carcinoma. Early recognition and initiation of steroid treatment will result in complete remission of the disease and prevent complications. (author)

Full Text Available Myelofibrosis is an indicator of poor prognosis in myeloproliferative neoplasms (MPNs, but the precise mechanism(s contributing to extracellular matrix remodeling and collagen deposition in the bone marrow (BM niche remains unanswered. In this study, we isolated mesenchymal stromal cells (MSCs from mice transplanted with wild-type thrombopoietin receptor (MPLWT and MPLW515L retroviral-transduced bone marrow. Using MSCs derived from MPLW515-transplant recipients, excessive collagen deposition was maintained in the absence of the virus and neoplastic hematopoietic cells suggested that the MSCs were reprogrammed in vivo. TGFβ production by malignant megakaryocytes plays a definitive role promoting myelofibrosis in MPNs. However, TGFβ was equally expressed by MSCs derived from MPLWT and MPLW515L expressing mice and the addition of neutralizing anti-TGFβ antibody only partially reduced collagen secretion in vitro. Interestingly, profibrotic MSCs displayed increased levels of pSmad3 and pSTAT3 suggesting that inflammatory mediators cooperating with the TGFβ-receptor signaling may maintain the aberrant phenotype ex vivo. FGFb is a known suppressor of TGFβ signaling. Reduced collagen deposition by FGFb-treated MSCs derived from MPLW515L mice suggests that the activating pathway is vulnerable to this suppressive mediator. Therefore, our findings have implications for the future investigation of therapies to reverse fibrosis in MPNs.

Idiopathic granulomatous mastitis (IGM) is a rare benign inflammatory breast disease that presents with variable local manifestations. We describe here the different management protocols based on the clinical presentation of these patients. A retrospective review of 20 histopathologic confirmed cases of IGM seen over a period of 10 years was performed. The median age was 34 years (age range: 21-45 years). All were married, parous with history of breast feeding. Ill-defined mass mimicking carcinoma was the commonest presentation (70%); however, with the presence of signs of inflammation like pain (55%), redness (40%), and peau d'orange (40%), an inflammatory process appeared more likely. Axillary lymph node enlargement was infrequently seen (40%). Radiologic findings (mammography and ultrasound) were nonspecific. Histopathology showed the characteristic lobular distribution of granulomatous inflammation in all cases. Surgically, 7 patients had abscess drainage with open biopsy, and 7 patients had lumpectomy. Six patients with diffuse breast involvement were diagnosed by core needle biopsy only. Microbial cultures showed no growth. Antibiotics were given empirically when signs of inflammation where present. Two patients needed further abscess drainage followed by persistent sinus excision 3-6 weeks later. The median follow-up was 24 months (range: 15-42 months). Seventeen patients (85%) were recurrence-free, and 3 patients (15%) were lost to follow-up. Management of IGM cases needs to be tailored according to the clinical presentation. Precise radiologic and pathologic data interpretation by a multidisciplinary breast team will facilitate diagnosis and minimize unnecessary intervention.

Idiopathic pulmonary hemosiderosis (IPH) is a rare disease characterized by the triad of hemoptysis, pulmonary infiltrates on chest radiograph, and anemia. Its diagnosis should be considered in any child presenting with moderate to severe anemia and failure to thrive of unclear etiology. Consideration of the differential diagnosis in such a child should include the review of both extravascular and intravascular causes of hemolysis. Systemic treatment of IPH with glucocorticoids has been shown to decrease morbidity, mortality, and disease progression to pulmonary fibrosis. Thus, diagnostic delays can impact prognosis. Here, we present a case of a 15-month-old boy with IPH who presented with anemia, jaundice, and failure to thrive, as well as a history of hemoptysis that was not initially elicited.

Pulmonary cryptococcosis in a ruxolitinib-treated patient with primary myelofibrosis

2017-01-01

Full Text Available We present the case of a 79-year-old man who showed multiple pulmonary nodules on chest computed tomography (CT after being treated for 6 months with ruxolitinib, an inhibitor of Janus kinase (JAK 1 and 2, to treat primary myelofibrosis. We examined the lesions by bronchoscopy, and the biopsy specimen revealed fungus bodies of Cryptococcus with granulomatous inflammation. As a result, the patient was diagnosed with pulmonary cryptococcosis. The patient was treated with fluconazole (200 mg daily for 2 weeks with concomitant ruxolitinib administration, but the pulmonary lesions progressed. Subsequently, the patient was treated with voriconazole (300 mg daily for 3 weeks, but the lesions worsened further. The administration of ruxolitinib was therefore discontinued, and the dosage of voriconazole was increased to 400 mg daily. Three months later, the pulmonary lesions diminished in size. The present case of pulmonary cryptococcosis occurred in a patient treated with ruxolitinib. Treatment of pulmonary cryptococcosis with concomitant JAK inhibitor administration may result in poor treatment efficacy. It might be better to stop administration of JAK inhibitors, if possible, in patients being treated for pulmonary cryptococcosis.

Full Text Available A 40-year-old lady presented with history of multiple red raised painful lesions over her body of 10 days duration. Lesions spread from forearms to arms and back of trunk during the progress of the disease. Associated pain and burning sensation in the lesions was present while working in the sun. Mild to moderate grade fever, malaise, pain over large joints, decreased appetite, and redness of eyes was also present. There was no history of drug intake or other risk-factors. Dermatological examination revealed erythematous papules coalescing to form plaques with a pseudovesicular appearance over the extensor aspect of forearms and photo-exposed areas on the back of trunk. There was a sharp cut-off between the lesions and the photo-protected areas. Investigations revealed anemia, neutrophilic leukocytosis, raised erythrocyte sedimentation rate and positive C reactive protein. Skin biopsy showed characteristic features of Sweet′s syndrome. No evidence for any secondary etiology was found. She responded to a tapering course of oral steroids and topical broad spectrum photo-protection. This case is a very rare instance of idiopathic Sweets syndrome occurring in a photo-distributed pattern.

Idiopathic anaphylaxis is a diagnosis of exclusion after other causes have been thoroughly evaluated and excluded. The pathogenesis of idiopathic anaphylaxis remains uncertain, although increased numbers of activated lymphocytes and circulating histamine-releasing factors have been implicated. Signs and symptoms of patients diagnosed with idiopathic anaphylaxis are indistinguishable from the manifestations of other forms of anaphylaxis. Treatment regimens are implemented based on the frequency and severity of patient symptoms and generally include the use of epinephrine autoinjectors, antihistamines, and steroids. The prognosis of idiopathic anaphylaxis is generally favorable with well-established treatment regimens and effective patient education. Copyright © 2015 Elsevier Inc. All rights reserved.

Polycythemia vera (PV) and essential thrombocythemia (ET) are myeloproliferative neoplasms with variable risk of evolution into post-PV and post-ET myelofibrosis, from now on referred to as secondary myelofibrosis (SMF). No specific tools have been defined for risk stratification in SMF. To develop a prognostic model for predicting survival, we studied 685 JAK2, CALR, and MPL annotated patients with SMF. Median survival of the whole cohort was 9.3 years (95% CI: 8-not reached-NR-). Through penalized Cox regressions we identified negative predictors of survival and according to beta risk coefficients we assigned 2 points to hemoglobin level <11 g/dl, to circulating blasts ⩾3%, and to CALR-unmutated genotype, 1 point to platelet count <150 × 10 9 /l and to constitutional symptoms, and 0.15 points to any year of age. Myelofibrosis Secondary to PV and ET-Prognostic Model (MYSEC-PM) allocated SMF patients into four risk categories with different survival (P<0.0001): low (median survival NR; 133 patients), intermediate-1 (9.3 years, 95% CI: 8.1-NR; 245 patients), intermediate-2 (4.4 years, 95% CI: 3.2-7.9; 126 patients), and high risk (2 years, 95% CI: 1.7-3.9; 75 patients). Finally, we found that the MYSEC-PM represents the most appropriate tool for SMF decision-making to be used in clinical and trial settings.

Myelofibrosis is a non-frequent chronic myeloproliferative Philadelphia-negative chromosome neoplasm. It is a heavy incapacitating orphan disease and associated with high morbidity and mortality. In this context, indirect and non-medical costs are expected to be high. The main objective of this project is to estimate the economic burden of this disease in Spain. Thirty-three patients with a diagnosis of myelofibrosis for at least 1 year participated in a questionnaire in three Spanish centers. The study consisted of analyzing in various aspects the cost and impact of the disease; indeed, daily life time limitations with a need of informal care, symtomatology. Additionally, information concerning the clinical management of the disease was collected through a focus group of eight experts. The mean age was 65 years. 15 of 33 patients were at their productive stage. Six had difficulties at work and eight have received informal care. Bone and muscular pain were the main symptoms of patients (72%). The estimated global indirect and non-medical costs of the disease were 86,315€ per patient (20% working and 80% informal care), which reached 104,153€ at productive stage patients (45%) and 168,459€ for more symptomatic patients. The economic burden of indirect and non-medical costs of myelofibrosis are important (15,142€/annual) as a result, and should be considered in economic evaluation, as well as in preventive plans for patients and caregivers, despite the fact that studies with larger numbers of patients should be done.

Myelofibrosis (MF) can present as a primary disorder or evolve from polycythemia vera (PV) or essential thrombocythemia (ET) to post-PV MF or post-ET MF, respectively. MF is characterized by bone marrow fibrosis, splenomegaly, leukoerythroblastosis, extramedullary hematopoiesis, and a collection of debilitating symptoms. Until recently, the therapeutic options for patients with MF consisted of allogeneic hematopoietic stem cell transplant (alloHSCT), the use of cytoreductive agents (ie, hydroxyurea), splenectomy and splenic irradiation for treatment of splenomegaly, and management of anemia with transfusions, erythropoiesis-stimulating agents (ESAs), androgens, and immunomodulatory agents. However, with increased understanding of the pathogenesis of MF resulting from dysregulated Janus kinase (JAK) signaling, new targeted JAK inhibitor therapies, such as ruxolitinib, are now available. The purpose of this article is to review the clinical features of MF, discuss the use and future of JAK inhibitors, reassess when and how to use conventional MF treatments in the context of JAK inhibitors, and provide a perspective on the future of MF treatment.

A Review of Ruxolitinib for the Treatment of Myelofibrosis: A Critique of the Evidence.

As part of the National Institute for Health and Care Excellence's (NICE) Single Technology Appraisal (STA) process, ruxolitinib was assessed to determine the clinical and cost effectiveness of its use in the treatment of disease-related splenomegaly or symptoms in adults with myelofibrosis. Ruxolitinib had previously been assessed as part of the STA process and was not recommended in NICE guidance issued in June 2013 (TA289). A review of TA289 was commissioned following the availability of new longer-term survival data; a price discount patient access scheme (PAS) was also introduced. The Centre for Reviews and Dissemination (CRD) and Centre for Health Economics (CHE) Technology Appraisal Group at the University of York was commissioned to act as the independent Evidence Review Group (ERG). This article provides a summary of the manufacturer or sponsor of the technology's (referred to as the company) submission, the ERG review and the resulting NICE guidance issued in March 2016. The main clinical effectiveness data were derived from two good-quality multicentre randomised controlled trials (RCTs): COMFORT-II compared ruxolitinib with best available therapy (BAT) and COMFORT-I compared ruxolitinib with placebo. Both RCTs demonstrated a statistically significant reduction in splenomegaly and its associated symptoms in intermediate-2 and high-risk myelofibrosis patients. Overall survival was statistically significantly improved with ruxolitinib compared with BAT at 3.5 years of follow-up in the COMFORT-II trial (hazard ratio 0.58, 95 % CI 0.36-0.93). Grade 3-4 adverse events were more frequent in the ruxolitinib group than in the BAT group; 42 % compared with 25 %. Evidence relating to patients with lower-risk disease or low platelet counts (50-100 × 10 9 /L) was less robust. The company's economic model was well-presented and had an appropriate model structure. The base-case incremental cost-effectiveness ratio (ICER) was estimated to be around £45,000 per

Myeloproliferative neoplasms are chronic disorders of clonal hematopoietic stem cells, characterized by an overproduction of functional granulocytes, red blood cells and / or platelets, and one of the major complications is the occurrence of venous and arterial thrombotic problems caused by increased platelet aggregation and thrombin generation. In this study 11 cases of primary myelofibrosis (PM) were evaluated and 2 debuted with splanchnic venous thrombosis (SVT); so after seeing the results of this study and of world literature, it is suggested that in patients with SVT, diagnostic methods for PM like the JAK2V617F mutation should be included.

During the last three years 77 patients with myelofibrosis were studied by scintigraphy, using 99m Tc colloids and 111 in transferring as tracers. Low axial uptake of the colloids, extension of the indium uptake beyond the axis towards the knees and sometimes the ankles and elbows, and splenic indium uptake are valuable diagnostic criteria, particularly useful to exclude myelofibrosis associated with a malignant disorder. The clinical severity of the disease, and in particular the disappearance of physiologically active bone marrow (indium uptake) can be predicted from isotopic studies. Bone marrow scintigraphy could contribute to the difficult decision of splenectomy.

Fanconi syndrome is a complex of multiple tubular dysfunctions of proximal tubular cells, occurring alone or in association with a variety of inherited (primary) or acquired (secondary) disorders. It is characterized by aminoaciduria, normoglycemic glycosuria, tubular proteinuria without hematuria, metabolic acidosis without anion gap and excessive urinary excretion of phosphorous, calcium, uric acid, bicarbonate, sodium, potassium and magnesium. Diabetes insipidus is a disease of collecting tubules and children mainly present with dehydration and hypernatremia. We are reporting the first case of idiopathic Fanconi's syndrome along with nephrogenic diabetes insipidus in a child who presented to us with vitamin D resistant rickets. Medline search did not reveal any case of nephrogenic diabetes insipidus (NDI) associated with idiopathic Fanconi syndrome. We hypothesized that the NDI may be due to to severe hypokalemia induced tubular dysfunction.

Full Text Available Asymmetric ventriculomegly due to idiopathic occlusion of the foramen of Monro is rare. Such patients present with clinical features of raised intracranial pressure (ICP. Presentation as chronic headache has not been previously described. In the absence of raised ICP, pursuing surgical treatment raises a clinical dilemma as the headache may be a primary headache with no improvement after surgery. A 21-year-old woman presented with chronic headache. She was found to have asymmetric ventriculomegaly due to the occlusion of the foramen of Monro. She underwent endoscopic septostomy and widening of the foramen of Monro. Her headache subsided after surgery. At 15 months of follow-up, she was free from headache without medications. Unilateral occlusion of the foramen of Monro can present with asymmetric ventriculomegaly resulting in chronic headache. Though the symptoms of raised ICP may not be present, still endoscopic relief of ventriculomegaly leads to cure of headache.

Approximately 50% of essential thrombocythaemia and primary myelo-fibrosis patients do not have a JAK2 V617F mutation. Up to 5% of these are reported to have a MPL exon 10 mutation but testing for MPL is not routine as there are multiple mutation types. The ability to routinely assess both JAK2 and MPL mutations would be beneficial in the differential diagnosis of unexplained thrombocytosis or myelofibrosis. We developed and applied a high resolution melt (HRM) assay, capable of detecting all known MPL mutations in a single analysis, for the detection of MPL exon 10 mutations. We assessed 175 ET and PMF patients, including 67 that were JAK2 V617F-negative by real time polymerase chain reaction (PCR). Overall, 19/175 (11%) patients had a MPL exon 10 mutation, of whom 16 were JAK2 V617F-negative (16/67; 24%). MPL mutation types were W515L (11), W515K (4), W515R (2) and W515A (1). One patient had both W515L and S505N MPL mutations and these were present in the same haemopoietic colonies. Real time PCR for JAK2 V617F analysis and HRM for MPL exon 10 status identified one or more clonal marker in 71% of patients. This combined genetic approach increases the sensitivity of meeting the World Health Organization diagnostic criteria for these myeloproliferative neoplasms.

Idiopathic granulomatous mastitis is a rare chronic inflammatory lesion of the breast that can clinically and radiographically mimic breast carcinoma. The most common clinical presentation is an unilateral, discrete breast mass, nipple retraction and even a sinus formation often associated with an inflammation of the overlying skin. The etiology of idiopathic granulomatous mastitis is still obscure. Its treatment remains controversial. The cause may be the autoimmune process, infection, a chemical reaction associated with oral contraceptive pills, or even lactation. Various factors, including hormonal imbalance, autoimmunity, unknown microbiological agents, smoking and α 1-antitrypsin deficiency have been suggested to play a role in disease aetiology. In this review, causing factors in the aetiology of idiopathic granulomatous mastitis are reviewed in detail.

Juvenile Idiopathic Arthritis

Full Text Available Juvenile idiopathic arthritis is the most common chronic rheumatic disease of unknown aetiology in childhood and predominantly presents with peripheral arthritis. The disease is divided into several subgroups, according to demographic characteristics, clinical features, treatment modalities and disease prognosis. Systemic juvenile idiopathic arthritis, which is one of the most frequent disease subtypes, is characterized by recurrent fever and rash. Oligoarticular juvenile idiopathic arthritis, common among young female patients, is usually accompanied by anti-nuclear antibodie positivity and anterior uveitis. Seropositive polyarticular juvenile idiopathic arthritis, an analogue of adult rheumatoid arthritis, is seen in less than 10% of paediatric patients. Seronegative polyarticular juvenile idiopathic arthritis, an entity more specific for childhood, appears with widespread large- and small-joint involvement. Enthesitis-related arthritis is a separate disease subtype, characterized by enthesitis and asymmetric lower-extremity arthritis. This disease subtype represents the childhood form of adult spondyloarthropathies, with human leukocyte antigen-B27 positivity and uveitis but commonly without axial skeleton involvement. Juvenile psoriatic arthritis is characterized by a psoriatic rash, accompanied by arthritis, nail pitting and dactylitis. Disease complications can vary from growth retardation and osteoporosis secondary to treatment and disease activity, to life-threatening macrophage activation syndrome with multi-organ insufficiency. With the advent of new therapeutics over the past 15 years, there has been a marked improvement in juvenile idiopathic arthritis treatment and long-term outcome, without any sequelae. The treatment of juvenile idiopathic arthritis patients involves teamwork, including an experienced paediatric rheumatologist, an ophthalmologist, an orthopaedist, a paediatric psychiatrist and a physiotherapist.

The clinical manifestations of MF include splenomegaly, consequent to extramedullary hematopoiesis, cytopenias, and an array of potentially debilitating abdominal and constitutional symptoms. Dysregulated Janus kinase (JAK-signal transducer and activator of transcription signaling underlies secondary disease-associated effects in MF, such as myeloproliferation, bone marrow fibrosis, constitutional symptoms, and cachexia. Common fatal complications of MF include transformation to acute leukemia, thrombohemorrhagic events, organ failure, and infections. Potential complications from hepatosplenomegaly include portal hypertension and variceal bleeding, whereas extramedullary hematopoiesis outside the spleen and liver – depending on the affected organ – may result in intracranial hypertension, spinal cord compression, pulmonary hypertension, pleural effusions, lymphadenopathy, skin lesions, and/or exacerbation of abdominal symptoms. Although allogeneic stem cell transplantation is the only potentially curative therapy, it is suitable for few patients. The JAK1/JAK2 inhibitor ruxolitinib is effective in improving splenomegaly, MF-related symptoms, and quality-of-life measures. Emerging evidence that ruxolitinib may be associated with a survival benefit in intermediate- or high-risk MF suggests the possibility of a disease-modifying effect. Consequently, ruxolitinib could provide a treatment backbone to which other (conventional and novel

Bone-marrow imaging with indium-111 chloride in aplastic anemia and myelofibrosis: concise communication

Twenty-nine patients with aplastic anemia and 11 patients with myelofibrosis were evaluated with indium-111 chloride bone-marrow imaging, ferrokinetics, and bone-marrow core biopsies. There was good correlation between the erythrocyte cellularity of the marrow and the In-111 bone-marrow scan grades in most patients. In some, the overall scan grade tended to underestimate the erythroid elements because the core biopsy had been taken from the area of the greatest radionuclide concentration on the scan. In patients with aplastic anemia, there was good correlation between the plasma iron clearance t1/2 and the scan grade. Less agreement was found in the comparison between the Fe-59 sacral and organ counts and the red-cell iron utilization. In patients with myelofibrosis, there was poor correlation between the surface counts over the sacrum and the red-cell iron utilization. Plasma iron clearances were abnormally short and were unrelated to the transferrin saturation levels. Eighteen patients were studied several times to evaluate their responses to steroid therapy. In all, there was good correlation between the bone-marrow imaging, the erythrocyte cellularity, ferrokinetics, and the patient's response to therapy. Indium-111 bone-marrow imaging is useful both in evaluating marrow erythroid activity and in following the response to therapy in patients with these diseases

Unilateral vocal fold paralysis with no preceding causes is diagnosed as idiopathic unilateral vocal fold paralysis. However, comprehensive guidelines for evaluating the defining characteristics of idiopathic unilateral vocal fold paralysis are still lacking. In the present study, we hypothesized that idiopathic unilateral vocal fold paralysis may have different clinical and neurologic characteristics from unilateral vocal fold paralysis caused by surgical trauma. Retrospective, case series study. Patients with unilateral vocal fold paralysis were evaluated using quantitative laryngeal electromyography, videolaryngostroboscopy, voice acoustic analysis, the Voice Outcome Survey, and the Short Form-36 Health Survey quality-of-life questionnaire. Patients with idiopathic and iatrogenic vocal fold paralysis were compared. A total of 124 patients were recruited. Of those, 17 with no definite identified causes after evaluation and follow-up were assigned to the idiopathic group. The remaining 107 patients with surgery-induced vocal fold paralysis were assigned to the iatrogenic group. Patients in the idiopathic group had higher recruitment of the thyroarytenoid-lateral cricoarytenoid muscle complex and better quality of life compared with the iatrogenic group. Idiopathic unilateral vocal fold paralysis has a distinct clinical presentation, with relatively minor denervation changes in the involved laryngeal muscles, and less impact on quality of life compared with iatrogenic vocal fold paralysis. 4.

Full Text Available Idiopathic rupture of the urinary bladder is an uncommon condition and represents less than 1% of all bladder rupture cases. In most of the cases the main etiological factor was heavy alcohol ingestion. A combined injury of the spleen and bladder is a very rare condition that is almost often associated with trauma and foreign bodies. In this paper we present the extremely rare clinical course of acute abdomen caused by a combined spontaneous intraperitoneal injury; spontaneous rupture of the urinary bladder and spleen. According to our opinion, spontaneous bladder rupture caused by bladder distension due to alcohol ingestion led to urinary ascites and abdominal distension. Finally, repeated minor abdominal blunt trauma during everyday life, to a moderately distended abdomen caused a spontaneous splenic rupture in the patient with abnormal coagulation studies.

Overall survival (OS) and other important clinical trial end-points seem increasingly more elusive in supporting rapid and efficient incorporation of innovative cancer drugs in clinical practice. This study proposes a clinical trial based pharmacoeconomic framework to assess the therapeutic and economic value of ruxolitinib in patients with intermediate-2 or high-risk myelofibrosis. Individual patient level 144 week follow-up data from the COMFORT-II trial was used to account for the crossover effect on overall survival. Lifetime treatment benefits and costs were estimated considering detailed patterns of both ruxolitinib dose adjustments and blood transfusion needs. The authors estimate a 3.3 years increment in life expectancy (HR = 0.30; 95% CI = 0.17-0.55; p-value <0.001) and an incremental cost-effectiveness ratio of €40,000 per life year gained with the use of ruxolitinib. This study also demonstrates how valuable information from clinical trials can be used to support informed decisions about the early incorporation of innovative drugs.

Idiopathic epileptic syndromes and cognition.

Epilepsy is frequently associated with cognitive impairments which result from various interacting factors. The present paper deals with the contribution of neuropsychology to the characterization of the type of epilepsy and the possible mechanisms underlying idiopathic epileptic syndromes. The non-lesional, so-called idiopathic epilepsies, constitute an interesting model for assessing the relationship between epileptiform EEG discharges and cognition. Among the idiopathic generalized epilepsies, disorders of social integration and personality have been frequently reported in juvenile myoclonic epilepsy (JME). Since similar disturbances are observed in frontal-lobe-lesioned patients, impairments in other frontal lobe functions (e.g. executive functions) might be expected in JME. This gives rise to speculation about the possible underlying pathophysiological mechanisms in JME. With regard to partial idiopathic epilepsies, benign childhood epilepsy with centrotemporal spikes (BCECTS) may provide a useful model for the study of the relationship between epileptiform EEG discharges in the peri-sylvian region and language functions. Furthermore, the description of mild cognitive dysfunctions in BCECTS, and their persistence into adulthood, can provide information about compensatory mechanisms and may allow for the generation of remedial strategies. Thus, 'lesional' neuropsychology has given way to 'dynamic' neuropsychology based on specific postulates. By using the cognitive profile to specify the mechanism underlying the behavioral disturbances observed in different types of epilepsy, neuropsychology may eventually contribute to a revision of the present classification of epileptic syndromes. In addition, the neuropsychological data may help predict the extent and limits of functional recovery and cerebral plasticity.

Idiopathic pulmonary fibrosis is a fibrosing interstitial pneumonia associated with the radiological and/or histological pattern of usual interstitial pneumonia. Its aetiology is unknown, but probably comprises the action of endogenous and exogenous micro-environmental factors in subjects with genetic predisposition. Its diagnosis is based on the presence of characteristic findings of high-resolution computed tomography scans and pulmonary biopsies in absence of interstitial lung diseases of other aetiologies. Its clinical evolution is variable, although the mean survival rate is 2-5 years as of its clinical presentation. Patients with idiopathic pulmonary fibrosis may present complications and comorbidities which modify the disease's clinical course and prognosis. In the mild-moderate disease, the treatment consists of the administration of anti-fibrotic drugs. In severe disease, the best therapeutic option is pulmonary transplantation. In this paper we review the diagnostic and therapeutic aspects of the disease. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

Psychiatric symptoms are present in most of the patients with idiopathic normal pressure hydrocephalus

Matheus F. Oliveira

2014-06-01

Full Text Available Normal pressure hydrocephalus (NPH is characterized by gait disturbance, dementia and/or urinary incontinence associated with dilation of ventricular system with normal opening cerebrospinal fluid pressure. Wide scientifical evidence confirms association between NPH and psychiatric symptoms. We selected 35 patients with idiopathic normal pressure hydrocephalus from January 2010 to January 2012 in a Brazilian tertiary hospital and performed a formal psychiatric evaluation to identify psychiatric disorders. Psychiatric disorders were present in 71% of these patients, especially anxiety, depression and psychotic syndromes. NPH patients may develop symptoms with frontal dominance, such as personality changes, anxiety, depression, psychotic syndromes, obsessive compulsive disorder, Othello syndrome; shoplifting and mania. Unusual appearances of NPH symptoms may hinder early diagnosis and consequently proper treatment.

A rare diagnosis of abdominal pain presentation in the emergency department: Idiopathic omental bleeding: A case report.

2017-12-01

Idiopathic omental bleeding is a rare cause of acute abdomen, with only a few reported cases. It usually presents with abdominal pain and may be life-threatening. As it rarely occurs, it may not be considered initially during patient presentation. A 35-year-old male came to our emergency department with abdominal pain present for around 5 to 6 hours. The patient complained of left upper quadrant abdominal pain after eating breakfast. The only associated symptom was 3 episodes of vomiting up food. Physical examination revealed mild left upper quadrant abdominal tenderness without muscle guarding or rebounding pain. Blood examination showed leukocytosis with neutrophil predominance and C reactive protein elevation. The pain was persistent and relief was not obtained by medication. Computed tomography showed a large lobular-contour homogenous slightly hyperdense lesion without enhancement along the greater curvature of the stomach in the lesser sac. A surgeon was consulted and laparotomy was suggested. Hematoma was found at Morrison pouch, subsplenic fossa, and lesser sac under operation. Laparotomy and ligation for hemostasis. The patient was discharged with stable condition after 7 days of hospitalization. This diagnosis should be considered in patients presenting with epigastric pain and vomiting after eating while in the emergency department because this disease might be life-threatening. This case highlights 2 important learning points. First, idiopathic omental bleeding could occur after eating in patients without underlying disease or trauma history, and this disease should be taken into consideration when acute abdomen occurs. Second, emergent laparotomy is indicated if the cause of acute abdomen is not clear. Copyright © 2017 The Authors. Published by Wolters Kluwer Health, Inc. All rights reserved.

Full Text Available Idiopathic spinal cord herniation is a rare and often missed cause of thoracic myelopathy. The clinical presentation and radiological appearance is inconsistent and commonly confused with a dorsal arachnoid cyst and often is a misdiagnosed entity. While ventral spinal cord herniation through a dural defect has been previously described, intravertebral herniation is a distinct entity and extremely rare. We present the case of a 70-year old man with idiopathic thoracic transdural intravertebral spinal cord herniation and discuss the clinico-radiological presentation, pathophysiology and operative management along with a review the literature of this unusual entity.

Acute megakaryoblastic leukemia (AML M7) is a biologically heterogeneous form of acute myeloid leukemia accounting for 14.6% of cases. In many instances in the past, AML M7 has been classified as undifferentiated leukemia, myelodysplasia, myelofibrosis or some other disease because of its complex clinical presentation or the difficulty of obtaining and interpreting bone marrow samples. However, with currently available morphological, cytochemical, cytogenetic and immunophenotypic methods, AML M7 can now be reliably diagnosed. Although the radiographic spectrum of bony changes in leukemia have been well characterized, skeletal X-ray abnormalities in the setting of AML M7 in pediatric patients have been described in few reports that were associated with bone marrow fibrosis. Here we report on a 14-month-old girl who presented with a massive periosteal reaction of the extremities and clavicles associated with myelofibrosis, a presenting feature of AML M7. The bone changes were very unusual in this case.

Full Text Available Scoliosis is called idiopathic when no other underlying disease can be identified. The etiology of adolescent idiopathic scoliosis (AIS is still unknown despite many years of research effort. Theories on AIS's etiology have included mechanical, hormonal, metabolic, neuromuscular, growth, and genetic abnormalities. Skeletally immature patients with adolescent idiopathic scoliosis are at risk of curve progression. The adolescent onset of severe idiopathic scoliosis has traditionally been evaluated using standing posteroanterior radiographs of the full spine to assess lateral curvature with the Cobb method. Scoliosis in children of school age and above primarily occurs in girls. The therapeutic goal in children is to prevent progression. In children, scoliosis of 20 and deg; or more should be treated with a brace, and scoliosis of 45 and deg; or more with surgery. [Arch Clin Exp Surg 2014; 3(3.000: 174-182

Traditionally, the treatment options for adolescent idiopathic scoliosis (AIS), the most common form of scoliosis, are exercises; in-patient rehabilitation; braces and surgery. The outcomes of treatments are usually compared with the natural history or observation (non-intervention). The aim of this paper was to provide a synopsis of all treatment options in the light of evidence based practice (EBP). A systematic review was carried out using the most encompassing databases available. Literature has been searched for the outcome parameter ''rate of progression'' and only prospective controlled studies that have considered the treatment versus the natural history have been included. The search strategy included the following terms: ''adolescent idiopathic scoliosis''; ''idiopathic scoliosis''; ''natural history''; ''observation''; ''physiotherapy''; ''physical therapy''; ''rehabilitation''; ''bracing''; ''orthotics'' and ''surgery''. Prospective short-term studies have been found to support outpatient physiotherapy. One prospective controlled study was found to support scoliosis in-patient rehabilitation (SIR). One prospective multi-centre study, a long-term prospective controlled study and a meta-analysis have been found to support bracing. No controlled study, neither short, mid nor long-term, was found to reveal any substantial evidence to support surgery as a treatment for this condition. There is some evidence supporting the conservative treatment for AIS. No substantial evidence has been found in terms of prospective controlled studies to support surgical intervention. In light of the unknown long-term effects of surgery, a randomised controlled trial (RCT) seems necessary. Due to the presence of evidence to support conservative treatments, a plan to compose a RCT for conservative treatment options seems unethical. But it is also important to conclude that the evidence for conservative treatments is weak in number and length.

Idiopathic intussusception is an important cause of abdominal pain, bleeding per rectum and intestinal obstruction in infancy and childhood. The main aim of this study was to undertake a retrospective review of all chidren who presented with idiopathic intussusception over a 17-year period. The medical record of children who presented idiopathic intussusception from January 1984 to December 2000 at King Fahad National Guard Hospital ,Riyadh, Kingdom of Saudi Arabia were reviewed. The data obtained included age, sex clincal presentation, diagonstic investigations, mode of treatment, length of hospital stay and results. Thirty-three chidren (21 male, 12female) presented with 37 episodes of intussusception.Their mean age was 8.4 months (range 5 hours to 36 months ). Clinical features included rectal bleeding (81%), vomiting (78%), abdominal colic/pain (65%) and abdominal mass (62%) .All cases were ileocolic intussusception with no leading point. Barium enema was attempted in 36 cases with success in 20 (56%). Laparotomy was required in 16 csaes, manual reduction being successful in 11(30%) and 6 (16%) had bowel resection. At surgery, after attempted Barium reduction, 9(56%) cases had the intussusception already reduced to cecum. Seventy percent of the cases presented within 24 hours of onset of the symptoms.The 4 recurrences in 3 children had successful enema reduction. There was no mortality but 3 operative cases of this type required late surgery for adhesive intestinal obstruction including one requiring bowel resection. Idiopathic indussusception commonly presents as an ileo-colic type but is uncommon in our institution. The clinical features are classical, rectal bleeding being the most common. The majority presented within 24 hours of onset of symptoms and Barium enema reduction was sucessfull in 20 out of 36 cases in which it was attempted . Since most intussusception were already in the cecum at surgey after failed enema reduction could be considerd in stable

Primary myelofibrosis belongs to the group of myeloproliferative syndromes. Extramedullary hematopoiesis in the liver can lead to portal hypertension. We report a case of a patient with life-threatening, endoscopically not treatable bleeding from esophageal varices due to extramedullary hematopoiesis of the liver that was successfully treated with placement of a transjugular intrahepatic porto-systemic stent-shunt (TIPS). Therapy of variceal bleeding by TIPS insertion was successful. During a 29-month follow-up, no hepatic failure, hepatic encephalopathy, or further variceal bleeding episode occurred. TIPS placement is a well-established procedure for the treatment of complications due to portal hypertension mainly due to liver cirrhosis. This report illustrates that TIPS placement can also be a promising treatment option in patients with primary myelofibrosis and portal hypertension due to extramedullary hematopoiesis.

Myelofibrosis (MF) is characterized by bone marrow fibrosis, progressive anemia and extramedullary hematopoiesis, primarily manifested as splenomegaly. Patients also experience debilitating constitutional symptoms, including sequelae of splenomegaly, night sweats and fatigue. Ruxolitinib (INC424, INCB18424, Jakafi, Jakavi), a JAK1 and JAK2 inhibitor, was approved in November 2011 by the US FDA for the treatment of intermediate- or high-risk MF, and more recently in Europe and Canada for the treatment of MF-related splenomegaly or symptoms. These approvals were based on data from two randomized Phase III studies: COMFORT-I randomized against placebo, and COMFORT-II randomized against best available therapy. In these studies, ruxolitinib rapidly improved multiple disease manifestations of MF, reducing splenomegaly and improving quality of life of patients and potentially prolonging survival. However, as with other chemotherapies, ruxolitinib therapy is associated with some adverse events, such as anemia and thrombocytopenia. The aims of this article are to provide a brief overview of ruxolitinib therapy, to discuss some common adverse events associated with ruxolitinib therapy and to provide clinical management recommendations to maximize patients' benefit from ruxolitinib.

Idiopathic granulomatous mastitis masquerading as carcinoma of the breast: a case report and review of the literature

Background Idiopathic granulomatous mastitis is an uncommon, benign entity with a diagnosis of exclusion. The typical clinical presentation of idiopathic granulomatous mastitis often mimics infection or malignancy. As a result, histopathological confirmation of idiopathic granulomatous mastitis combined with exclusion of infection, malignancy and other causes of granulomatous disease is absolutely necessary.

Idiopathic retroperitoneal fibrosis (RPF) is a rare disease entity and its etiology is uncertain. We report two similar cases which showed an uncommon presentation of idiopathic RPF. A 66-year-old woman and an 80-year-old man presented with incidental findings of left renal pelvic mass-like lesions. Computed tomography revealed a soft tissue density mass replacing the left renal pelvis, which was suspicious for renal pelvic cancer, and the diagnosis of idiopathic RPF was surgically confirmed. To the best of our knowledge, a few cases of idiopathic RPF presenting with features of a localized unilateral renal pelvic mass mimicking renal pelvic cancer have been reported

Intestinal Volvulus in Idiopathic Steatorrhea

Science.gov (United States)

Warner, H. A.; Kinnear, D. G.; Cameron, D. G.

1963-01-01

Volvulus of the intestine has recently been observed in three patients with idiopathic steatorrhea in relapse. Two patients gave a history of intermittent abdominal pain, distension and obstipation. Radiographic studies during these attacks revealed obstruction at the level of the sigmoid colon. Reduction under proctoscopic control was achieved in one instance, spontaneous resolution occurring in the other. The third patient presented as a surgical emergency and underwent operative reduction of a small intestinal volvulus. Persistence of diarrhea and weight loss postoperatively led to further investigation and a diagnosis of idiopathic steatorrhea. In all cases, treatment resulted in clinical remission with a coincident disappearance of obstructive intestinal symptoms. The pathogenesis of volvulus in sprue is poorly understood. Atonicity and dilatation of the bowel and stretching of the mesentery likely represent important factors. The symptoms of recurrent abdominal pain and distension in idiopathic steatorrhea necessitate an increased awareness of intestinal volvulus as a complication of this disease.

Myelofibrosis (MF) is a bone marrow disorder characterized by clonal myeloproliferation, aberrant cytokine production, extramedullary hematopoiesis, and bone marrow fibrosis. Although somatic mutations in JAK2, MPL, and CALR have been identified in the pathogenesis of these diseases, inhibitors of the Jak2 pathway have not demonstrated efficacy in ameliorating MF in patients. TGF-β family members are profibrotic cytokines and we observed significant TGF-β1 isoform overexpression in a large cohort of primary MF patient samples. Significant overexpression of TGF-β1 was also observed in murine clonal MPLW515L megakaryocytic cells. TGF-β1 stimulated the deposition of excessive collagen by mesenchymal stromal cells (MSCs) by activating the TGF-β receptor I kinase (ALK5)/Smad3 pathway. MSCs derived from MPLW515L mice demonstrated sustained overproduction of both collagen I and collagen III, effects that were abrogated by ALK5 inhibition in vitro and in vivo. Importantly, use of galunisertib, a clinically active ALK5 inhibitor, significantly improved MF in both MPLW515L and JAK2V617F mouse models. These data demonstrate the role of malignant hematopoietic stem cell (HSC)/TGF-β/MSC axis in the pathogenesis of MF, and provide a preclinical rationale for ALK5 blockade as a therapeutic strategy in MF.

PATTERN OF INHERITANCE OF IDIOPATHIC HYPERCALCIURIA IN TWO FAMILIES

Directory of Open Access Journals (Sweden)

A. Nickavar

2006-09-01

Full Text Available Idiopathic hypercalciuria is a leading cause of frequency-dysuria syndrome in childhood. Different modes of inheritance have been suggested in this disease. This article presents the occurrence of idiopathic hypercalciuria in all children of two families. In the first family, a 5.5 year old girl with a history of renal stones and dysuria due to hypercalciuria, had two involved brothers and one sister. In the second family, hypercalciuria and medullary nephrocalcinosis were detected in two siblings who were admitted for polyuria and dysuria. Idiopathic type of hypercalciuria was diagnosed in these two families by normal laboratory exams and exclusion of other causes of normocalcemic hypercalciuria. According to the involvement of all offsprings (both sexes in these two families, it is suggested that idiopathic hypercalciuria is an autosomal dominant disease with complete penetration.

Less than 5% of patients with polycythemia vera (PV) show JAK2 exon 12 mutations. Although PV patients with JAK2 exon 12 mutations are known to develop post-PV myelofibrosis (MF) as well as PV with JAK2V617F, the role of JAK inhibitors in post-PV MF patients with JAK2 exon 12 mutations remains unknown. We describe how treatment with a JAK1/2 inhibitor, ruxolitinib, led to the rapid amelioration of marrow fibrosis, erythrocytosis and thrombocytopenia in a 77-year-old man with post-PV MF who carried a JAK2 exon 12 mutation (JAK2H538QK539L). This case suggests that ruxolitinib is a treatment option for post-PV MF in patients with thrombocytopenia or JAK2 exon 12 mutations.

Orthodontic treatment in patient with idiopathic root resorption: A case report

Diego Rey

2015-02-01

Full Text Available Multiple idiopathic external root resorption is a rare pathological condition usually detected as an incidental radiographic finding. External root resorption of permanent teeth is a multifactorial process related to several local and systemic factors. If an etiological factor cannot be identified for root resorption, the term "idiopathic" is applied. This report presents a case of multiple idiopathic apical root resorption. The condition was found in a young female patient seeking orthodontic treatment due to malocclusion. This kind of resorption starts apically and progresses coronally, causing a gradual shortening and rounding of the remaining root. Patients with this condition are not the ideal candidates for orthodontic treatment; however, the aim of this report is to describe an unusual case of idiopathic root resorption involving the entire dentition, and to present the orthodontic treatment of this patient. It describes the progress and completion of orthodontic therapy with satisfactory end results.

Computed tomography in the assessment of idiopathic spontaneous pneumothorax

International Nuclear Information System (INIS)

Kim, Sang Jin; Lee, Doo Yun; Kim, Hyung Jung

1991-01-01

It is well known that idiopathic spontaneous pneumothorax is caused by rupture of the subpleural bleb and presents difficulty in exact detection and localization of the bleb with plain chest X - ray alone. The authors performed chest CT scans for accurate diagnosis of bleb that would act as a guide for optimal management of idiopathic spontaneous pneumothorax patients in order to prevent recurrent pneumothorax. We could detect blebs in 93 % (26/28) of the patients with idiopathic spontaneous pneumothorax, and 68 % (19/ 28) of the patient had bilateral blebs. Sensitivity was 0.63, and false negative was 37% (37/100) of the blebs, and 51% (19/37) of these 37 false negative cases were ruptured blebs. Only 7 % (2/28) of the patients had a single bleb. The authors concluded that CT is a useful method of study for optimal management of idiopathic spontaneous pneumothorax patients

Idiopathic Fanconi's syndrome with nephrogenic diabetes insipidus in a child who presented as vitamin D resistant rickets--a case report and review of literature.

Fanconi's syndrome is a complex of multiple tubular dysfunctions of proximal tubular cells occurring alone or in association with a variety of inherited (primary) or acquired (secondary) disorders. It is characterized by aminoaciduria, normoglycemic glycosuria, tubular proteinuria without hematuria, metabolic acidosis without anion gap and excessive urinary excretion of phosphorous, calcium, uric acid, bicarbonate, sodium, potassium and magnesium. Diabetes insipidus is a disease of collecting tubules and a child mainly presents with dehydration and hypernatremia. We report the first case of idiopathic Fanconi's syndrome along with nephrogenic diabetes insipidus (NDI) in a child who presented to us as resistant rickets. Medline search did not reveal any case of nephrogenic diabetes insipidus associated with idiopathic Fanconi's syndrome. We hypothesized that the NDI may be due to severe hypokalemia induced tubular dysfunction. The child was treated for hypophosphatemic rickets with severe metabolic acidosis and the treatment for NDI was also given. Now he has healed rickets and normal blood pH, sodium and osmolarity.

Full Text Available Nada Jirásková, Pavel RozsívalDepartment of Ophthalmology, University Hospital, Hradec Králové, Czech RepublicPurpose: To evaluate retrospectively the features, treatment, and outcome of idiopathic intracranial hypertension (IIH in children.Methods: Nine patients, 15 years and younger, diagnosed with IIH. Inclusion criteria were papilledema, normal brain computer tomography or magnetic resonance imaging, cerebrospinal fluid pressure greater than 250 mm H2O, normal cerebrospinal fluid content, and a nonfocal neurologic examination except for sixth nerve palsy.Results: Of the nine patients, eight were girls. Five girls were overweight and one boy was obese. The most common presenting symptom was headache (5 patients. Diplopia or strabismus did not occur in our group. Visual field abnormalities were present in all eyes, and severe visual loss resulting in light perception vision occurred in both eyes of one patient. Eight patients were treated medically with acetazolamide alone, and one girl needed a combination of acetazolamide and corticosteroids. This girl also required optic nerve sheath decompression surgery. Resolution of papilledema and recovery of visual function occurred in all patients.Conclusions: Idiopathic intracranial hypertension in prepubertal children is rather uncommon. Prompt diagnosis and management are important to prevent permanent visual loss.Keywords: idiopathic intracranial hypertension, pediatric, treatment

Frameshift mutations in the calreticulin (CALR) gene are seen in about 30% of essential thrombocythemia and myelofibrosis patients. To address the contribution of the CALR mutants to the pathogenesis of myeloproliferative neoplasms, we engrafted lethally irradiated recipient mice with bone marrow cells transduced with retroviruses expressing these mutants. In contrast to wild-type CALR, CALRdel52 (type I) and, to a lesser extent, CALRins5 (type II) induced thrombocytosis due to a megakaryocyte (MK) hyperplasia. Disease was transplantable into secondary recipients. After 6 months, CALRdel52-, in contrast to rare CALRins5-, transduced mice developed a myelofibrosis associated with a splenomegaly and a marked osteosclerosis. Monitoring of virus-transduced populations indicated that CALRdel52 leads to expansion at earlier stages of hematopoiesis than CALRins5. However, both mutants still specifically amplified the MK lineage and platelet production. Moreover, a mutant deleted of the entire exon 9 (CALRdelex9) did not induce a disease, suggesting that the oncogenic property of CALR mutants was related to the new C-terminus peptide. To understand how the CALR mutants target the MK lineage, we used a cell-line model and demonstrated that the CALR mutants, but not CALRdelex9, specifically activate the thrombopoietin (TPO) receptor (MPL) to induce constitutive activation of Janus kinase 2 and signal transducer and activator of transcription 5/3/1. We confirmed in c-mpl- and tpo-deficient mice that expression of Mpl, but not of Tpo, was essential for the CALR mutants to induce thrombocytosis in vivo, although Tpo contributes to disease penetrance. Thus, CALR mutants are sufficient to induce thrombocytosis through MPL activation. © 2016 by The American Society of Hematology.

In the era before Janus kinase (JAK) inhibitors, cytogenetic information was used to predict survival in myelofibrosis patients. However, the prognostic value of cytogenetics in the setting of JAK inhibitor therapy remains unknown. We performed a retrospective analysis of 180 patients with bone marrow biopsy-proven myelofibrosis from 3 US academic medical centers. We fit Cox proportional hazards models for overall survival and transformation-free survival on the bases of 3 factors: JAK inhibitor therapy as a time-dependent covariate, dichotomized cytogenetic status (favorable vs. unfavorable), and statistical interaction between the two. The median follow-up time was 37.1 months. Among patients treated with best available therapy, unfavorable cytogenetic status was associated with decreased survival (hazard ratio = 2.31; P = .025). At initiation of JAK inhibitor therapy, unfavorable cytogenetics was (nonsignificantly) associated with increased survival compared to favorable cytogenetics (hazard ratio = 0.292; P = .172). The ratio of hazard ratios was 0.126 (P = .034). These findings were similar after adjusting for standard clinical prognostic factors as well as when measured against transformation-free survival. The initiation of JAK inhibitor therapy appears to change the association between cytogenetics and overall survival. There was little difference in survival between treatment types in patients with favorable cytogenetics. However, the use of JAK inhibitor therapy among patients with unfavorable cytogenetics was not associated with worse survival compared to favorable cytogenetics. Our analyses suggest that initiation of JAK inhibitor therapy nullifies the negative prognostic implication of unfavorable cytogenetics established in the pre-JAK inhibitor therapy era.

Evidence for cognitive vestibular integration impairment in idiopathic scoliosis patients

Directory of Open Access Journals (Sweden)

Mercier Pierre

2009-08-01

Full Text Available Abstract Background Adolescent idiopathic scoliosis is characterized by a three-dimensional deviation of the vertebral column and its etiopathogenesis is unknown. Various factors cause idiopathic scoliosis, and among these a prominent role has been attributed to the vestibular system. While the deficits in sensorimotor transformations have been documented in idiopathic scoliosis patients, little attention has been devoted to their capacity to integrate vestibular information for cognitive processing for space perception. Seated idiopathic scoliosis patients and control subjects experienced rotations of different directions and amplitudes in the dark and produced saccades that would reproduce their perceived spatial characteristics of the rotations (vestibular condition. We also controlled for possible alteration of the oculomotor and vestibular systems by measuring the subject's accuracy in producing saccades towards memorized peripheral targets in absence of body rotation and the gain of their vestibulo-ocular reflex. Results Compared to healthy controls, the idiopathic scoliosis patients underestimated the amplitude of their rotations. Moreover, the results revealed that idiopathic scoliosis patients produced accurate saccades to memorized peripheral targets in absence of body rotation and that their vestibulo-ocular reflex gain did not differ from that of control participants. Conclusion Overall, results of the present study demonstrate that idiopathic scoliosis patients have an alteration in cognitive integration of vestibular signals. It is possible that severe spine deformity developed partly due to impaired vestibular information travelling from the cerebellum to the vestibular cortical network or alteration in the cortical mechanisms processing the vestibular signals.

Performing a pretransplantation splenectomy in patients with myelofibrosis (MF) is a matter of debate, as while the procedure improves hematological recovery, it may lead to severe morbidities. We retrospectively analyzed data from 85 consecutive patients who underwent transplantation in our center for MF, including 39 patients who underwent splenectomy before their transplantation. A majority of them had primary MF (78%), were considered high-risk patients (84% dynamic international prognostic scoring system intermediate-2 or higher), and had received transplants from HLA-matched sibling donors (56%) after a reduced-intensity conditioning regimen (82%). One-half of all splenectomized patients presented surgical or postsurgical morbidities, most frequently thrombosis and hemorrhage. After adjustment using Cox models, pretransplantation splenectomy was not associated with nonrelapse mortality or post-transplantation relapse but with an improved overall survival (OS) and event-free survival (EFS). We conclude that some patients with huge splenomegaly may undergo pretransplantation splenectomy without a deleterious impact on post-transplantation outcomes. OS and EFS improvement should in confirmed in controlled study. Copyright © 2017 The American Society for Blood and Marrow Transplantation. Published by Elsevier Inc. All rights reserved.

2006-10-01

Full Text Available Abstract Background Scoliosis is the most common type of spinal deformity. In North American children, adolescent idiopathic scoliosis (AIS makes up about 90% of all cases of scoliosis. While its prevalence is about 2% to 3% in children aged between 10 to 16 years, girls are more at risk than boys for severe progression with a ratio of 3.6 to 1. The aim of the present study was to test the hypothesis that idiopathic scoliosis interferes with the mechanisms responsible for sensory-reweighting during balance control. Methods Eight scoliosis patients (seven female and one male; mean age: 16.4 years and nine healthy adolescents (average age 16.5 years participated in the experiment. Visual and ankle proprioceptive information was perturbed (eyes closed and/or tendon vibration suddenly and then returned to normal (eyes open and/or no tendon vibration. An AMTI force platform was used to compute centre of pressure root mean squared velocity and sway density curve. Results For the control condition (eyes open and no tendon vibration, adolescent idiopathic scoliosis patients had a greater centre of pressure root mean squared velocity (variability than control participants. Reintegration of ankle proprioception, when vision was either available or removed, led to an increased centre of pressure velocity variability for the adolescent idiopathic scoliosis patients whereas the control participants reduced their centre of pressure velocity variability. Moreover, in the absence of vision, adolescent idiopathic scoliosis exhibited an increased centre of pressure velocity variability when ankle proprioception was returned to normal (i.e. tendon vibration stopped. The analysis of the sway density plot suggests that adolescent idiopathic scoliosis patients, during sensory reintegration, do not scale appropriately their balance control commands. Conclusion Altogether, the present results demonstrate that idiopathic scoliosis adolescents have difficulty in

We describe a patient with idiopathic hemifacial spasm (HFS) that was responsive to zonisamide treatment. A 65-year-old woman presented with a 4-year history of left-sided HFS developing gradually, starting from the upper facial muscles. After several analyses, the diagnosis of idiopathic HFS was made, and the clonazepam treatment (0.5 mg every 8 hours) was started, without a complete remission of symptoms. Therefore, zonisamide (150 mg twice a day for a 6-week period) was added, with a complete resolution. The rechallenge with zonisamide after its dechallenge confirmed its effectiveness. During follow-up, the patient remained symptom-free, with no adverse drug reactions. We suggest that zonisamide could represent a useful therapeutic option in the treatment of idiopathic HFS.

Idiopathic photosensitive occipital lobe epilepsy (IPOE) is an idiopathic localization-related epilepsy characterized by age-related onset, specific mode of precipitation, occipital photic-induced seizures--frequently consisting of visual symptoms--and good prognosis. This uncommon epilepsy, which usually starts in childhood or adolescence, has rarely been observed in families in which idiopathic generalized epilepsy also affects other members. We describe a nuclear family in which the proband showed electro-clinical features of idiopathic photosensitive occipital lobe epilepsy in childhood, which subsequently evolved into absences and a single generalized tonico-clonic seizure in early adolescence. His mother had features suggestive of juvenile myoclonic epilepsy. This case illustrates a continuum between focal and generalized entities in the spectrum of the so-called idiopathic (genetically determined) epileptic syndromes.

Myelofibrosis is a haematopoietic stem cell neoplasm characterized by bone marrow inflammation, reactive marrow fibrosis and extramedullary haematopoiesis. The aim of this study was to determine if {sup 18}F-FDG PET/CT can be used to noninvasively visualize and quantify the extent and activity of bone marrow involvement. In 30 patients, the biodistribution of {sup 18}F-FDG was analysed by measuring the standardized uptake value in the bone marrow compartment and spleen. Imaging findings were compared with laboratory, cytogenetic and histopathological data. Retention of {sup 18}F-FDG was observed in bone marrow and spleen. Bone marrow involvement varied, ranging from mildly increased uptake in the central skeleton to extensive uptake in most parts of the skeleton. The extent of bone marrow involvement decreased over time from initial diagnosis (r{sub s} = -0.43, p = 0.019). Metabolic activity of the bone marrow decreased as the histopathological grade of fibrosis increased (r{sub s} = -0.37, p = 0.04). There was a significant positive correlation between the metabolic activity of the bone marrow and that of the spleen (p = 0.04). {sup 18}F-FDG PET/CT is as a promising technique for the quantitation of bone marrow inflammation in myelofibrosis. Our data indicate that the intensity of bone marrow {sup 18}F-FDG uptake decreases as bone marrow fibrosis increases. Further evaluation in prospective studies is required to determine the potential clinical impact and prognostic significance of PET. (orig.)

Full Text Available Myeloproliferative neoplasms (MPNs are clonal hematopoietic stem cell disorders characterized by proliferation of one or more cell lineages in the bone marrow. At present, the main criterion in the 2008 World Health Organization classification of MPNs is the presence of an underlying genetic abnormality. These mutations are generally mutually exclusive except for rare reports in the literature. We report for the first time a detailed analysis of the clinical, histologic and cytogenetic/molecular features of a patient who initially presented with MPL W515L positive primary myelofibrosis and over the course of five years developed an MPN associated with both BCR-ABL1 and MPL W515L mutation. We discuss the diagnostic challenges and therapeutic implications of concomitant BCR-ABL1 translocation with MPL W515L mutation. Multiple genetic alterations may simultaneously coexist in patients exhibiting features of myeloproliferative disorders.

To find the tree in the forest - radiological presentation of idiopathic interstitial pneumonias

Full text: Idiopathic Interstitial Pneumonias (IIP) are a large group of diffuse parenchymal lung diseases which have similar clinical and radiographic characteristics and at the same time they are completely different which separates them as a nosological units. The aim of this report is: to present the modern classification built on consensus between the Thoracal American Association and the European Respiratory Association; to illustrate the main CT characteristics in individual IIP and, where is possible, comparison with histopathological changes; to present the methodological approach in the process of differentiation of individual diseases in the group based on the individual X-ray characteristics, clinical presentation and expected prognosis. American Thoracic Association and the European Respiratory Association offer classes consensus classification of IIP, published in 2002, defining the morphological characteristics on the basis of which it is based and radiological-pathological diagnosis of IIP. Radiographic evaluation of the IIP is difficult because various changes can exist in a patient's lung, while the same nosological units can be represented with different X-ray picture depending on the gravity of his occurrence. Clinical evaluation is not a real diagnostic, but together with the conventional X-Ray findings, the functional study of respiration and CT image can give deferential diagnostics effect. The distinction between different IIP is particularly important due to the different prognosis, that each of these diseases carries. Authors stress on the importance of the interdisciplinary team for the correct final diagnosis, based on a correlation between clinical picture, imaging and histopathological findings

Idiopathic pulmonary fibrosis (IPF), also known as cryptogenic fibrosing alveolitis, is one of a spectrum of idiopathic interstitial pneumonia. IPF is an increasingly common condition which poses many diagnostic and therapeutic challenges leading to misdiagnosis and mismanagement. We presented a 55-year-old male textile trader who was initially managed as sputum-negative pulmonary tuberculosis before histology report. He presented to our clinic with Breathlessness and cough of 3 years and 2.5 years, respectively. He had commenced anti-tuberculosis two months before presentation without significant relief. General Physical examination and vital signs were essentially normal. SPO2 was 96% on room air. Chest Examination revealed end-inspiratory bi-basal velcro-like crackles. Other systemic examinations were normal. Radiological examination by way of chest X- ray and chest CT showed features suggestive of IPF. The patient also had open Lung biopsy for histology and spirometry which demonstrated restrictive ventilatory function pattern. A diagnosis of Interstitial lung disease probably Idiopathic Pulmonary Fibrosis was entertained. He was commenced on Tab prednisolone, Tab Rabeprazole, with minimal improvement. IPF have often been misdiagnosed and treated as pulmonary tuberculosis with unfavorable outcome.

2017-01-01

We conducted a 17-year nationwide survey (1999-2015) to elucidate the clinical outcomes of patients with primary myelofibrosis (PMF) in Japan. Questionnaires were sent annually to approximately 500 hematology departments. Newly diagnosed patients with PMF were enrolled in this study, and were followed up annually to collect prognostic information. Approximately 50 patients were enrolled per year, yielding a total of 780 patients with PMF included in this study. The median age at diagnosis was 66 years. At the time of analysis, the median survival duration was 47 months, and the 3-year overall survival rate was 59 %. Infection and disease transformation into acute leukemia were the most frequent causes of death. Of the proposed prognostic models for predicting the outcomes of PMF patients in Japan, the Dynamic International Prognostic Scoring System of PMF plus model was the most feasible. Forty-three patients received allogeneic hematopoietic stem cell transplantation (alloSCT) at a median of 343 days after diagnosis. This treatment significantly prolonged the survival of PMF patients, and the 3-year overall survival rate after first alloSCT was 84 %. A long-term registration study is required for further evaluation of prognosis and the impact of treatments on survival.

Full Text Available Introduction. Harlequin syndrome is a very rare neurological condition characterized by redness and excessive sweating of one half of the face in response to exercise and emotions. In most cases this disorder is not life-threatening. Objective. To present diagnostic difficulties of Harlequin syndrome in dermatological practice. Case report. We present a case of a 30-year-old man with redness and excessive sweating of the right half of the face as a result of exercise that was observed during the diagnosis of chronic urticaria at the Department of Dermatology. The patient was examined ophthalmologically and neurologically, had a CT scan of the head, and the Minor test performed. Idiopathic Harlequin syndrome was diagnosed based on case history and workup results. Conclusions . Harlequin syndrome occurs most often in the form of an idiopathic condition, but neurologic and ophthalmologic assessment should be performed since some diseases, such as brainstem infarction and schwannoma of the upper chest, may initially appear as Harlequin syndrome.

Pulmonary function in children with idiopathic scoliosis

2012-03-01

Full Text Available Abstract Idiopathic scoliosis, a common disorder of lateral displacement and rotation of vertebral bodies during periods of rapid somatic growth, has many effects on respiratory function. Scoliosis results in a restrictive lung disease with a multifactorial decrease in lung volumes, displaces the intrathoracic organs, impedes on the movement of ribs and affects the mechanics of the respiratory muscles. Scoliosis decreases the chest wall as well as the lung compliance and results in increased work of breathing at rest, during exercise and sleep. Pulmonary hypertension and respiratory failure may develop in severe disease. In this review the epidemiological and anatomical aspects of idiopathic scoliosis are noted, the pathophysiology and effects of idiopathic scoliosis on respiratory function are described, the pulmonary function testing including lung volumes, respiratory flow rates and airway resistance, chest wall movements, regional ventilation and perfusion, blood gases, response to exercise and sleep studies are presented. Preoperative pulmonary function testing required, as well as the effects of various surgical approaches on respiratory function are also discussed.

Idiopathic pulmonary fibrosis. A rare cause of scintigraphic ventilation-perfusion mismatch

A case of idiopathic pulmonary fibrosis with multiple areas of mismatch on ventilation-perfusion lung imaging in the absence of pulmonary embolism is presented. Idiopathic pulmonary fibrosis is one of the few nonembolic diseases producing a pulmonary ventilation-perfusion mismatch. In this condition, chest radiographs may not detect the full extent of disease, and xenon-133 ventilation imaging may be relatively insensitive to morbid changes in small airways. Thus, when examining patients with idiopathic pulmonary fibrosis, one should be aware that abnormal perfusion imaging patterns without matching ventilation abnormalities are not always due to embolism. In this setting, contrast pulmonary angiography is often needed for accurate differential diagnosis

Idiopathic Scoliosis

Full Text Available Idiopathic scoliosis (IS is a lifetime condition and is defined as a structural, lateral rotated curvature of the spine of >10° on standing coronal plane radiographs. It should be distinguished from other causes of scoliosis. It can be classified as infantile, juvenile, and adolescent according to age. As a rule of thumb, about 80% of all curves are idiopathic, right convex thoracic, and present in otherwise healthy girls at the beginning of puberty. A family member most commonly detects scoliosis. The structural asymmetry of the spine is best observed by asking the patient to bend forward. IS is often seen in more than one member of a family, but the aetiology remains unknown. Multiple genes are likely to be involved with incomplete penetrance and variable expressivity. Early detection by screening allows for monitoring curve progression and timely initiation of bracing, but school screening is controversial and practises vary worldwide. Most patients have minor scoliosis and treatment is generally not recommended for patients with curves 45°. Scoliosis surgery was not successful until the introduction of Harrington’s instrumentation in the 1960s. Modern instrumentation has evolved from the Cotrel-Dubousset system in the 1980s, and a variety of methods are available today. Although scoliosis may be a burden, long-term studies suggest that a good quality of life is maintained in most patients.

2014-04-01

Primary myelofibrosis (PMF), essential thrombocythemia (ET), and polycythemia vera (PV) are BCR ABL-negative myeloproliferative neoplasms (MPN). Published epidemiology data are scarce, and multiple sources are needed to assess the disease burden. We assembled the most recent information available on the incidence and prevalence of myelofibrosis (MF), ET, and PV by conducting a structured and exhaustive literature review of the published peer-reviewed literature in EMBASE and by reviewing online documentation from disease registries and relevant health registries in European countries. The search was restricted to human studies written in English or French and published between January 1, 2000, and December 6, 2012. Eleven articles identified from EMBASE, three online hematology or oncology registries, and two Web-based databases or reports were used to summarize epidemiological estimates for MF, PV, and ET. The incidence rate of MF ranged from 0.1 per 100,000 per year to 1 per 100,000 per year. Among the various registries, the incidence of PV ranged from 0.4 per 100,000 per year to 2.8 per 100,000 per year, while the literature estimated the range of PV incidence to be 0.68 per 100,000 to 2.6 per 100,000 per year. The estimated incidence of ET was between 0.38 per 100,000 per year and 1.7 per 100,000 per year. While a few studies reported on the MPNs' prevalences, it is difficult to compare them as various types of prevalence were calculated (point prevalence vs. period prevalence) and standardization was made according to different populations (e.g., the world population and the European population). There is a wide variation in both prevalence and incidence estimates observed across European data sources. Carefully designed studies, with standardized definitions of MPNs and complete ascertainment of patients including both primary and secondary MFs, should be conducted so that estimates of the population aimed to receive novel treatments for these neoplasms are

Understanding Splenomegaly in Myelofibrosis: Association with Molecular Pathogenesis

Directory of Open Access Journals (Sweden)

Moo-Kon Song

2018-03-01

Full Text Available Myelofibrosis (MF is a clinical manifestation of chronic BCR-ABL1-negative chronic myeloproliferative neoplasms. Splenomegaly is one of the major clinical manifestations of MF and is directly linked to splenic extramedullary hematopoiesis (EMH. EMH is associated with abnormal trafficking patterns of clonal hematopoietic cells due to the dysregulated bone marrow (BM microenvironment leading to progressive splenomegaly. Several recent data have emphasized the role of several cytokines for splenic EMH. Alteration of CXCL12/CXCR4 pathway could also lead to splenic EMH by migrated clonal hematopoietic cells from BM to the spleen. Moreover, low Gata1 expression was found to be significantly associated with the EMH. Several gene mutations were found to be associated with significant splenomegaly in MF. In recent data, JAK2 V617F homozygous mutation was associated with a larger spleen size. In other data, CALR mutations in MF were signigicantly associated with longer larger splenomegaly-free survivals than others. In addition, MF patients with ≥1 mutations in AZXL1, EZH1 or IDH1/2 had significantly low spleen reduction response in ruxolitinib treatment. Developments of JAK inhibitors, such as ruxolitinib, pacritinib, momelotinib, and febratinib enabled the effective management in MF patients. Especially, significant spleen reduction responses of the drugs were demonstrated in several randomized clinical studies, although those could not eradicate allele burdens of MF.

Full Text Available Chronic pain after dental implantation is rare but difficult issue for the implant practitioner. Patients with chronic pain who had been performed previous implant surgery or related surgical intervention sometimes accompany with psychological problem and difficult to adequately manage. According to the International Classification of Headache Disorders (ICHD 3rd eds, Cepalagia 2013, painful neuropathies and other facial pains are subdivided into the 12 subcategories; 13.1. Trigeminal neuralgia; 13.2 Glossopharyngeal neuralgia; 13.3 Nervus intermedius (facial nerve neuralgia; 13.4 Occipital neuralgia; 13.5 Optic neuritis; 13.6 Headache attributed to ischaemic ocular motor nerve palsy; 13.7 Tolosa-Hunt syndrome; 13.8 Paratrigeminal oculo-sympathetic (Raeder’s syndrome; 13.9 Recurrent painful ophthalmoplegic neuropathy; 13.10 Burning Mouth Syndrome (BMS; 13.11 Persistent Idiopathic Facial Pain (PIFP; 13.12 Central neuropathic pain. Chronic orofacial pain after dental implant surgery can be largely into the two main categories that can be frequently encountered in clinical basis ; 1 Neuropathic pain, 2 Idiopathic pain. If there is no direct evidence of the nerve injury related with the implant surgery, the clinician need to consider the central cause of pain instead of the peripheral cause of the pain. There might be several possibilities; 1 Anaesthesia dolorosa, 2 Central post-stroke pain, 3 Facial pain attributed to multiple sclerosis, 4 Persistent idiopathic facial pain (PIFP, 5 Burning mouth syndrome. In this presentation, Persistent idiopathic facial pain (PIFP, the disease entity that can be frequently encountered in the clinic would be discussed. Persistent idiopathic facial pain (PIFP can be defined as “persistent facial and/or oral pain, with varying presentations but recurring daily for more than 2 hours per day over more than 3 months, in the absence of clinical neurological deficit”. ‘Atypical’ pain is a diagnosis of

Scrotal elephantiasis is very rare disease in industrialized countries, where it is mainly due to surgery, irradiation or malignancies. It can be defined as idiopathic only when the possible congenital, infectious and compressive causes are excluded. We report a case of massive scrotal lymphoedema in an adult Caucasian patient, in Italy. He presented an extremely voluminous scrotal mass measuring 50 x 47 x 13 cm (weight 18 kg), which extended below his knees, invalidating all his daily activities. The patient was hospitalized in order to undergo to surgical treatment. Although genetic causes were searched and the possible role of infectious agents and compressive factors was evaluated, no etiology was ascertained. Histopathologic examination showed non-specific chronic inflammation, confirming the diagnosis of idiopathic elephantiasis. One year after surgical treatment, the patient is healthy without recurrence signs.

2003-01-01

To describe the clinical and MRI findings in three children with acute idiopathic myelopathy (AIM). Retrospective review of the clinical presentation, MRI findings and outcome of three patients diagnosed with acute idiopathic transverse myelitis. Of note was the swift onset of symptoms in all patients, without any preceding illness or history of vaccination in two of the patients, and the rapid resolution of symptoms on steroid therapy in all the patients. MRI showed T2-weighted hyperintensity and patchy enhancement with gadolinium, but the extensive cord involvement did not correlate with the severity of presentation or outcome. Our findings do not support that MRI evidence alone of diffuse myelopathy is a predictor of poor outcome in childhood AIM. (orig.)

2001-05-01

A case of chronic idiopathic intestinal pseudo-obstruction in an English bulldog is described. The dog was presented with chronic weight loss and vomiting. An intestinal obstruction was suspected based on clinical and radiological findings. A diagnosis of chronic idiopathic intestinal pseudo-obstruction was made on the basis of full thickness intestinal biopsies. The dog was refractory to any antiemetic therapy. Necropsy revealed marked atrophy and fibrosis of the tunica muscularis, together with a mononuclear cell infiltrate extending from the duodenum to the colon. This case was presented with clinical findings consistent with visceral myopathy in humans--namely, atony and dilatation of the whole gut--but the histological findings resembled sclerosis limited to the gastrointestinal tract.

2014-01-01

Full Text Available Idiopathic thrombocytopenic purpura (ITP is defined as a hematologic disorder, characterized by isolated thrombocytopenia without a clinically apparent cause. The major causes of accelerated platelet consumption include immune thrombocytopenia, decreased bone marrow production, and increased splenic sequestration. The clinical presentation may be acute with severe bleeding, or insidious with slow development with mild or no symptoms. The initial laboratory tests useful at the first visit to predict future diagnosis were erythrocyte count, leukocyte count, anti-glycoprotein IIb/IIIa antibodies, reticulated platelets, plasma thrombopoietin level. Treatment should be restricted to those patients with moderate or severe thrombocytopenia who are bleeding or at risk of bleeding. We present a case report on ITP with clinical presentation, diagnosis and management.

Strock, Stephen B; Alder, Jonathan K; Kass, Daniel J

2018-04-01

Patients with idiopathic pulmonary fibrosis have a significantly increased risk for the development of lung cancer. The morbidity and mortality of this disease combination are substantial, and, unfortunately, there are currently few data to help guide clinicians in its diagnosis and treatment. In a recent issue of this journal, Hwang et al presented one of the first studies to evaluate lung cancer in patients with idiopathic pulmonary fibrosis at the molecular level. They demonstrate variants in regulators of the cell cycle, which are known to be important in malignant transformation and may also be important in the pathogenesis of idiopathic pulmonary fibrosis. Further understanding of the pathogenic overlap between lung cancer and idiopathic pulmonary fibrosis could help point the direction to specific diagnostic modalities and targeted treatment of both conditions in the future.

Some patients with interstitial lung disease (ILD) related to connective tissue disease (CTD) have a delayed diagnosis of the underlying CTD when the ILD is categorized as idiopathic. In this study, we evaluated the frequency of myositis autoantibodies in patients diagnosed with idiopathic ILD and investigated the clinical significance stemming from the presence of the antibodies. A total 32 patients diagnosed with idiopathic ILD were enrolled in this study. We analyzed a panel of 11 myositis autoantibody specificities in the patients using a line blot immunoassay. Then, we divided them into myositis autoantibody-positive and -negative groups and compared the clinical features and laboratory data between the two groups. Of the 32 idiopathic ILD patients, 12 patients had myositis autoantibodies encompassing 9 specificities, except for anti-Mi-2 and anti-PM-Scl 100 (12/32, 38%). Anti-synthetase autoantibodies including Jo-1, EJ, OJ, PL-7, and PL-12 were present in 7 patients (7/32, 22%). The group with myositis autoantibodies presented more frequently with the symptom of mechanic's hand and showed abnormal pulmonary function test results with low forced vital capacity, diffusing capacity for carbon monoxide, total lung capacity, and high lactate dehydrogenase values in blood when compared with the group without myositis antibodies. We strongly suggest that patients undergo an evaluation of myositis autoantibodies, if they are diagnosed with idiopathic ILD in the presence of clinical characteristics including mechanic's hand, arthralgia, and autoantibodies which are insufficient to make a diagnosis of a specific CTD category.

SUMMARY - 'Idiopathic' herniation of the brain is a rare entity previously reported in 13 cases. It may be incidentally encountered in neuroimaging studies acquired for various clinical indications. We herein describe two cases of idiopathic brain herniation that were incidentally diagnosed. A 12-year-old boy presented with a six-month history of daytime sleepiness and sudden spells of sleep. Herniation of the left inferior temporal gyrus was revealed in MRI acquired with the suspicion of epilepsy. His overnight polysomnogram and multiple sleep latency tests were compatible with the diagnosis of narcolepsy. The other case, a two-year-old girl, was transferred from an outside hospital due to partial seizures with the fever. Herniation of the precuneal gyrus was encountered in MRI acquired after controlling her seizures with the initiation of phenytoin. The brain herniations of both patients were considered to be inconsistent with their medical conditions, so that they were symptom-free with only medical treatment for following three and six months, respectively. This is a rare presentation of idiopathic brain herniation as an incidental finding that accompanied narcolepsy and epilepsy. Awareness of this entity would avoid excessive surgical and medical treatments.

Study Design: Cross-sectional descriptive study Place and Duration of Study: Molecular Department of Haematology, Armed Forces Institute of Pathology (AFIP), Rawalpindi from Jul 2011 to Jul 2012. Patients and Methods: Ninety three consecutive patients of Polycythaemia vera (PV), Essential thrombocythaemia (ET) and Idiopathic myelofibrosis (IMF) diagnosed by the conventional haematological criteria were included in the study. All patients were screened for G-T point mutation (V617F) in the JAK2 gene on chromosome 9 by an allele specific PCR. Results: Out of the 93 myeloproliferative neoplasm (MPN) patients, 33(35%) had polycythaemia vera, 36(39%) had essential thrombocythaemia and 24(26%) had idiopathic myelofibrosis. JAK2 mutation was seen in 64/93 (69%) patients including 33/33(100%) in PV, 19/36(52.6%) in ET and 12/24(50%) in IMF. Conclusion: Classical myeloproliferative neoplasms are an important group of heamatological disorder in our country. JAK2 gene mutation is seen in significant proportion of these disorders (69%). JAK2 mutation analysis can be used to differentiate between polycythemia vera and secondary polycythemia in most cases with near certainty, where it was found in 100% of the cases. (author)

An autopsy case of myelofibrosis is reported and is literarily discussed. The patient was a 30-year-old man and was exposed to sublethal dose of radiation at 1.1 km from the hypocenter at the time of the explosion in Nagasaki Prefecture, when he was 10 months old. Serious bone marrow disturbances were suspected. About 25 years after the exposure, clinical symptoms like aplastic anemia were shown and this disease developed. Hepatosplenomegaly was not clinically found until the late period. The liver weighed 3180 g and the spleen weighed 1540 g at autopsy. Blood examination revealed low value of neutrophilic alkaline phosphatase only at the late period, and no abnormal chromosome was seen in the peripheral blood. Reticulum-like cells were not histologically found at biopsy, but were found at autopsy. Extramedullary hematopoiesis, always accompanied with bleeding, was observed not only in the spleen, the liver and the lymphnodes, but also in the dura mater, the stomach, the renal pelves and so on. It was the direct cause of death. (Kanao, N.)

2016-03-01

Full Text Available ABSTRACT Scoliosis is characterized by three-dimensional changes of the spine and is estimated to be present in 4% of the population worldwide. The most common form is the adolescent idiopathic. The purpose of this study is to identify the major muscle abnormalities found in patients with adolescent idiopathic scoliosis through a literature review. We conducted an electronic search of the national databases PubMed, Lilacs, PEDro, and EMBASE using the keywords "scoliosis", "biomechanics", "exercise", "physical therapy specialty", "idiopathic", and "muscles", from January 2003 to April 2015. The most relevant articles in English, Portuguese and Spanish were selected by title and abstract. It was also performed a manual search of the references of the selected articles. From a total of 4,319 articles, 11 were selected. We conclude that individuals with AIS have changes in the paraspinal muscles, with a difference in activation between the concave and convex sides, suggesting an increase in EMG activity on the convex side, although there is still no consensus among the authors.

To evaluate clinical signs, describe lesions and differences in the magnetic resonance imaging appearance of spinal new bone formations classified as disseminated idiopathic spinal hyperostosis and/or spondylosis deformans on radiographs and compare degeneration status of the intervertebral discs using the Pfirrmann scale. Retrospective analysis of 18 dogs presented with spinal disorders using information from radiographic and magnetic resonance imaging examinations. All dogs were found to be affected with both disseminated idiopathic spinal hyperostosis and spondylosis deformans. Neurological signs due to foraminal stenosis associated with disseminated idiopathic spinal hyperostosis were found in two dogs. Spondylosis deformans was associated with foraminal stenosis and/or disc protrusion in 15 cases. The Pfirrmann score on magnetic resonance imaging was significantly higher in spondylosis deformans compared with disseminated idiopathic spinal hyperostosis and signal intensity of new bone due to disseminated idiopathic spinal hyperostosis was significantly higher compared to spondylosis deformans. Differences between disseminated idiopathic spinal hyperostosis and spondylosis deformans found on magnetic resonance imaging contribute to an increased differentiation between the two entities. Clinically relevant lesions in association with disseminated idiopathic spinal hyperostosis were rare compared to those seen with spondylosis deformans. © 2014 British Small Animal Veterinary Association.

We describe with multimodal imaging the presentation and follow-up for a patient with idiopathic multifocal choroiditis and a transient peripapillary white ring. Case report. A 39-year-old Asian woman was initially seen for an evaluation of lattice degeneration in 2015. Her medical history included Graves disease and psoriasis. Best-corrected visual acuity was 20/25 in her right eye and 20/25 in her left eye. Ultra-widefield fundus autofluorescence imaging showed a curvilinear hyperautofluorescent line in her right eye. One year later, the patient returned complaining of floaters in her right eye for 1 month. Her visual acuity was unchanged. Funduscopic examination showed new inflammatory yellowish lesions in the right eye corresponding to hyperreflective sub-retinal pigment epithelium lesions on structural spectral domain optical coherence tomography. Fluorescein angiography showed corresponding late staining of these active lesions. Late-phase indocyanine green angiography showed multiple nummular hypocyanescent dots. Ultra-widefield fundus autofluorescence showed large areas of hyperautofluorescence. The patient was started on a 60-mg oral prednisone taper and demonstrated subsequent regression of the inflammatory lesions. Ten months later, the patient returned emergently with complaints of floaters in both eyes for 2 days and a new temporal scotoma in her left eye. Funduscopic examination demonstrated a white ring around the optic nerve of the left eye corresponding to a hyperautofluorescent lesion. Ultra-widefield fundus autofluorescence showed new areas of hyperautofluorescence in both eyes. Structural spectral domain optical coherence tomography showed new sub-retinal pigment epithelium inflammatory lesions and a disruption of the ellipsoid zone in both eyes. The patient was again treated with a 60-mg oral prednisone taper and demonstrated subsequent restoration of the ellipsoid zone. To our knowledge, this is the first report of a transient annular white

A patient with idiopathic myelofibrosis of some 20 yr duration developed esophageal varices and ascites. No explanation for increased portal pressure other than hepatic hematopoiesis was found. Consequently, a trial of cobalt irradiation to the liver was undertaken with definite but transient decrease in ascites. Subsequently, two courses of radioactive colloidal gold were given, again with definite but transient beneficial effects on the degree of ascites. This latter benefit occurred without suppression of marrow function

We report an unusual case of chronic mesenteric ischemia presenting in a 12-year-old girl with idiopathic infantile arterial calcinosis (IIAC). This is the first reported case in the literature of chronic mesenteric ischemia in the setting of IIAC. The girl presented with a classical history of postprandial abdominal pain. Imaging demonstrated significant stenoses of the celiac axis, superior mesenteric artery (SMA) and inferior mesenteric artery (IMA). Angioplasty of the celiac axis and SMA was attempted, with successful dilation of the SMA only. At 3-, 6- and 12-month follow-ups, the child's symptoms had almost resolved. This case report has three important ramifications: chronic mesenteric ischemia is a possible clinical presentation in children with IACC, pre-angioplasty imaging is important in guiding treatment approach, and angioplasty was effective in this case of chronic mesenteric ischemia and offers hope for other similarly affected children.

Mahesh Jayachandran

2013-01-01

Full Text Available Gingival enlargements are quite common and may be either inflammatory, noninflammatory, or a combination of both. Gingival hyperplasia is a bizarre condition causing esthetic, functional, psychological, and masticatory disturbances of the oral cavity. Causes of gingival enlargement can be due to plaque accumulation, due to poor oral hygiene, inadequate nutrition, or systemic hormonal stimulation (Bakaeen and Scully, 1998. It can occur as an isolated disease or as part of a syndrome or chromosomal abnormality. A progressive fibrous enlargement of the gingiva is a facet of idiopathic fibrous hyperplasia of the gingiva (Carranza and Hogan, 2002; Gorlin et al., 1976. It is described variously as fibromatosis gingivae, gingivostomatitis, hereditary gingival fibromatosis, idiopathic fibromatosis, familial elephantiasis, and diffuse fibroma. We present a case of idiopathic gingival fibromatosis with its multidisciplinary approach of management.

Idiopathic pulmonary fibrosis: treatment update.

LENUS (Irish Health Repository)

O'Connell, Oisin J

2011-11-01

Idiopathic pulmonary fibrosis (IPF) is the most common of the idiopathic interstitial pneumonias. Despite multiple recent clinical trials, there is no strong evidence supporting a survival advantage for any agent in the management of patients with IPF. The limited effectiveness of current treatment regimes has led to a search for novel therapies including antifibrotic strategies. This article reviews the evidence supporting the treatments currently used in the management of IPF.

Idiopathic facial palsy is the most common cause of facial nerve palsy in children. Controversy exists regarding treatment options. The objectives of this study were to review the epidemiological and clinical characteristics as well as the outcome of idiopathic facial palsy in children to suggest appropriate treatment. A retrospective study was conducted on children with a diagnosis of idiopathic facial palsy from 2007 to 2012. A total of 37 cases (13 males, 24 females) with a mean age of 13.9 years were included in this analysis. The mean duration between onset of Bell's palsy and consultation was 3 days. Of these patients, 78.3% had moderately severe (grade IV) or severe paralysis (grade V on the House and Brackmann grading). Twenty-seven patients were treated in an outpatient context, three patients were hospitalized, and seven patients were treated as outpatients and subsequently hospitalized. All patients received corticosteroids. Eight of them also received antiviral treatment. The complete recovery rate was 94.6% (35/37). The duration of complete recovery was 7.4 weeks. Children with idiopathic facial palsy have a very good prognosis. The complete recovery rate exceeds 90%. However, controversy exists regarding treatment options. High-quality studies have been conducted on adult populations. Medical treatment based on corticosteroids alone or combined with antiviral treatment is certainly effective in improving facial function outcomes in adults. In children, the recommendation for prescription of steroids and antiviral drugs based on adult treatment appears to be justified. Randomized controlled trials in the pediatric population are recommended to define a strategy for management of idiopathic facial paralysis. Copyright © 2015 Elsevier Masson SAS.

2013-05-01

Full Text Available OBJECTIVES: Familial steroid-sensitive idiopathic nephrotic syndrome is rare, and only approximately 3% of patients have affected siblings. METHODS: Herein, we report seven cases of patients with steroid-sensitive idiopathic nephrotic syndrome from three Chinese families. Mutational screening of the Nphs2 gene was performed in all the patients. RESULTS: All seven of the familial steroid-sensitive idiopathic nephrotic syndrome cases in our sample exhibited minimal change disease, and one case also presented with mesangial proliferative glomerulonephritis, according to the renal pathology. No significant was associations were found between Nphs2 gene mutations and the onset of proteinuria and nephrotic syndrome in these familial cases. CONCLUSIONS: The presence of minimal change disease is important, but it is not an unusual finding in patients with familial steroid-sensitive idiopathic nephrotic syndrome, which appears to be clinically benign and genetically distinct from other types of nephrosis.

Spontaneous Cerebrospinal Fluid Rhinorrhea as the Presenting Symptom of Idiopathic Intracranial Hypertension: A Case Series

Hossein Ghalaenovi

2018-05-01

Full Text Available Although rare, Cerebrospinal Fluid (CSF Leakage can result in deadly complications such as meningitis and brain abscess. Previously, primary spontaneous CSF leakage was referred to leakages without any detectable causes. However, it has been found recently that it may be related to abnormal increased intracranial pressure (ICP. Here, we reported demographic, clinical, and therapeutic features in addition to the outcomes of five patients with Idiopathic Intracranial Hypertension (IIH presented with spontaneous CSF leakage as the initial symptom. Four of our patients were female. The mean age was 38 years old. Rhinorrhea was the first manifestation of the CSF leakage in our patients. Ethmoidal cells were the most common site of leakage. The mean opening pressures (OP was 31.3 cmH2O. The computed tomography (CT scan and magnetic resonance imaging (MRI of the brain was normal in all patients except one patient showing fullness in left ethmoidal cells. In all of the patients, cerebral CT cisternography was diagnostic to detect the site of leakage. CSF leak in two patients resolved with medical therapy but CSF diversion procedure was mandatory in other three patients. CSF leakage resolved in all of them. CSF leakage can be the first and only presenting symptom of abnormal increased ICP. The key point in patient treatment is controlling the elevated ICP, even though some patients may need to CSF diversion procedure eventually.

2009-01-01

Full Text Available Abstract Background To gain more insight in whether failure of intrauterine insemination (IUI treatment in patients with idiopathic subfertility could be related to diminished fertilization, the aim of this study is to compare the fertilization of an initial IVF procedure after six cycles of IUI and the fertilization of an initial IVF procedure without preceding IUI cycles in couples with idiopathic subfertility. Methods We performed a complimentary analysis of a randomized controlled trial, in which the number of total fertilization failure (TFF in the first IVF procedure after unsuccessful IUI was compared to those of IVF without preceding IUI in patients with idiopathic subfertility. These patients participated in a previous study that assessed the cost effectiveness of IUI versus IVF in idiopathic subfertility and were randomized to either IUI or IVF treatment. Results 45 patients underwent IVF after 6 cycles of unsuccessful IUI and 58 patients underwent IVF immediately without preceding IUI. In 7 patients the IVF treatment was cancelled before ovum pick. In the IVF after unsuccessful IUI group TFF was seen in 2 of the 39 patients (5% versus 7 of the 56 patients (13% in the immediate IVF group. After correction for confounding factors the TFF rate was not significantly different between the two groups (p = 0.08, OR 7.4; 95% CI: 0.5–14.9. Conclusion Our data showed that TFF and the fertilization rate in the first IVF treatment were not significantly different between couples with idiopathic subfertility undergoing IVF after failure of IUI versus those couples undergoing IVF immediately without prior IUI treatment. Apparently, impaired fertilization does not play a significant role in the success rate of IUI in patients with idiopathic subfertility.

Full Text Available Abstract Introduction It has been reported that the prognosis of optic perineuritis may be poor when initiation of treatment is delayed. Here we report the successful treatment of three patients with idiopathic optic perineuritis, including two in whom initiation of therapy was delayed. Case presentation Three Japanese patients (two women aged 73 and 66 years, and one man aged 27 years presented with loss of vision (for five months, several months, and two months respectively and pain on eye movement in the third case only, and were diagnosed as having idiopathic optic perineuritis. Fat-suppressed T2-weighted magnetic resonance images showed high signal intensity areas around the affected optic nerves, suggesting the presence of optic perineuritis. Two patients received steroid pulse therapy and the third was given high-dose steroid therapy. The visual acuity improved in all three cases. Conclusion High-dose steroid therapy may be effective for idiopathic perineuritis in patients without optic nerve atrophy, even if initial treatment (including moderate-dose steroids has failed.

Jaime Eduardo Bernal Villegas

2012-08-01

Full Text Available Intrauterine growth restriction is a complication of pregnancy with a high probability of perinatal morbidity and mortality. It appears tobe caused by abnormal development of placental vasculature. Haemostatic processes are important for the development of the placenta,and an imbalance between procoagulant and anticoagulant factors has been associated with risk of intrauterine growth restriction.Objective. To evaluate coagulation abnormalities in placenta of pregnancies complicated with idiopathic intrauterine growth restriction.Materials and methods. Five placentas from pregnancies with idiopathic intrauterine growth restriction were compared to 19 controls.We performed gross and histological examination of the placenta. Analysis was made of both mRNA expression by real-time PCRand protein by ELISA of tissue factor and thrombomodulin in placental tissue. Results. Results based on histological evaluation wereconsistent with an increased prothrombotic state in placentas from pregnancies with idiopathic intrauterine growth restriction, andthrombosis of chorionic vessels was the most important finding. The study showed an increased expression of tissue factor protein(p=0.0411 and an increase in the ratio of tissue factor/thrombomodulin mRNA (p=0.0411 and protein (p=0.0215 in placentas frompregnancies with idiopathic intrauterine growth restriction. There were no statistically significant differences neither between cases andcontrols in the mRNA levels of tissue factor or thrombomodulin nor at the protein level of thrombomodulin. Conclusion. Evidence ofalteration of local haemostatic mechanisms at the level of the placenta, including abnormal expression of tissue factor and tissue factor/thrombomodulin ratio, in pregnancies that occur with idiopathic intrauterine growth restriction is presented.

Saravanan Balachandran

2014-01-01

Full Text Available Aneurysms of external carotid artery are rare. Treatments for these are undertaken for the prevention of complications like hemorrhage or rupture, and embolism. We present a 71-year-old male with idiopathic multiple aneurysm for the past 34 years on conservative management and regular follow up for the past 4 years. This case was discussed for the rarity of idiopathic multiple aneurysm of the external carotid artery and the need for individualized treatment protocol to be followed as in this case, only watchful observation considering the age and patient compliance. In this world of evolving surgical techniques and newer treatment modalities, conservative treatment still has a role to play. Primary care physicians at the community level have a major role in following these patients and referring them as and when the need arises.

Increased granulocytic, erythrocytic, and megakaryocytic progenitors in myelofibrosis with myeloid metaplasia

International Nuclear Information System (INIS)

Chikkappa, G.; Carsten, A.L.; Chanana, A.D.; Chandra, P.; Cronkite, E.P.

1978-01-01

Nucleated cells obtained from blood and/or bone marrow of patients with myelofibrosis with myeloid metaplasia (MMM) were cultured in diffusion chambers (DC) implanted into the peritoneal cavities of irradiated mice. A total of five blood studies and two bone marrow studies were performed using cells obtained from five patients. The DC were harvested at intervals from the host mice and the total and differential cellularity of DC contents were evaluated. The results obtained from MMM cultures were compared with those from similar cultures of blood cells and marrow cells of four and six normal individuals respectively. The proliferation and maturation of the granulocytic, erythrocytic, and megakaryocytic lines in MMM cultures occurred in an orderly fashion as they occur in vivo. The patterns of proliferation and maturation of the three cell lines in cultures after day 7 suggest that they primarily originate from progenitor cells. The numbers of granulocytes in the multiplicative pool, recognizable red cell precursors, and megakaryocytes recovered were significantly greater from the MMM cultures than those from the normal blood or marrow cultures. These results suggest that the blood and marrow cells of MMM patients have increased numbers of progenitors for granulocytes, erythrocytes and megakaryocytes

Towards a new taxonomy of idiopathic orofacial pain.

There is no current consensus on the taxonomy of the different forms of idiopathic orofacial pain (stomatodynia, atypical odontalgia, atypical facial pain, facial arthromyalgia), which are sometimes considered as separate entities and sometimes grouped together. In the present prospective multicentric study, we used a systematic approach to help to place these different painful syndromes in the general classification of chronic facial pain. This multicenter study was carried out on 245 consecutive patients presenting with chronic facial pain (>4 months duration). Each patient was seen by two experts who proposed a diagnosis, administered a 111-item questionnaire and filled out a standardized 68-item examination form. Statistical processing included univariate analysis and several forms of multidimensional analysis. Migraines (n=37), tension-type headache (n=26), post-traumatic neuralgia (n=20) and trigeminal neuralgia (n=13) tended to cluster independently. When signs and symptoms describing topographic features were not included in the list of variables, the idiopathic orofacial pain patients tended to cluster in a single group. Inside this large cluster, only stomatodynia (n=42) emerged as a distinct homogenous subgroup. In contrast, facial arthromyalgia (n=46) and an entity formed with atypical facial pain (n=25) and atypical odontalgia (n=13) could only be individualised by variables reflecting topographical characteristics. These data provide grounds for an evidence-based classification of idiopathic facial pain entities and indicate that the current sub-classification of these syndromes relies primarily on the topography of the symptoms.

Assessing idiopathic pulmonary fibrosis (IPF) with bronchoscopic OCT (Conference Presentation)

Science.gov (United States)

Hariri, Lida P.; Adams, David C.; Colby, Thomas V.; Tager, Andrew M.; Suter, Melissa J.

2016-03-01

Idiopathic pulmonary fibrosis (IPF) is a progressive, fatal form of fibrotic lung disease, with a 3 year survival rate of 50%. Diagnostic certainty of IPF is essential to determine the most effective therapy for patients, but often requires surgery to resect lung tissue and look for microscopic honeycombing not seen on chest computed tomography (CT). Unfortunately, surgical lung resection has high risks of associated morbidity and mortality in this patient population. We aim to determine whether bronchoscopic optical coherence tomography (OCT) can serve as a novel, low-risk paradigm for in vivo IPF diagnosis without surgery or tissue removal. OCT provides rapid 3D visualization of large tissue volumes with microscopic resolutions well beyond the capabilities of CT. We have designed bronchoscopic OCT catheters to effectively and safely access the peripheral lung, and conducted in vivo peripheral lung imaging in patients, including those with pulmonary fibrosis. We utilized these OCT catheters to perform bronchoscopic imaging in lung tissue from patients with pulmonary fibrosis to determine if bronchoscopic OCT could successfully visualize features of IPF through the peripheral airways. OCT was able to visualize characteristic features of IPF through the airway, including microscopic honeycombing (< 1 mm diameter) not visible by CT, dense peripheral fibrosis, and spatial disease heterogeneity. These findings support the potential of bronchoscopic OCT as a minimally-invasive method for in vivo IPF diagnosis. However, future clinical studies are needed to validate these findings.

Full Text Available Background: MRI screening for idiopathic scoliosis is controversial. Considering our clinical experiences, the results of MRI in all patients with idiopathic scoliosis were evaluated. Methods: In a prospective clinical study, all neurologically normal patients with idiopathic scoliosis screened by posterior fossa and total spine MRI. Results: After excluding 9 patients for mild neurological findings, in other 177 patients (132 female, 45 male, the average age and curve angle was 15±2 years and 59±17º (30 to 135º, respectively. Convexity was to right in 146 and to left in 31 cases. MRI was positive in 12 cases (6.8%. In 5 cases (2.8%, neurosurgical intervention was necessary prior to scoliosis surgery. There was no relation between age, sex, presence of pain or curve angle and positive MRI findings (P>0.05. Left convexity was significantly related to positive MRI findings (P=0.013. In males with left convex curves, the probability of positive MRI findings was 8.8 folds other patients. Conclusion: Considering our results and other reported articles, it seems that routine MRI screening of all patients presenting as idiopathic scoliosis is necessary for detection of underlying pathologies.

Idiopathic intracranial hypertension (IIH) is a condition of yet unknown aetiology affecting predominantly obese females of childbearing age. IIH is a diagnosis of exclusion as raised cerebrospinal fluid pressure may occur secondary to numerous other medical conditions. An atypical phenotype...... or an atypical disease course should alert the physician to reevaluate a presumed IIH-diagnosis. The authors report a case of a 32-year-old non-obese male with intracranial hypertension, secondary to a syphilitic central nervous system infection, initially misdiagnosed as being idiopathic.

Our objective was to measure short- and long-term outcomes of children presenting with recalcitrant idiopathic epistaxis. The study was an 11-year (2000-2011) retrospective chart review of children evaluated and treated for epistaxis. A retrospective review of patients with diagnostic International Classification of Diseases, Ninth Revision code 784.7 (epistaxis) and 21.5/21.88 (septoplasty) was completed reviewing age at presentation, type of surgery, and number of bleeding events prior to and after surgery. In our cohort, almost 100% of children with idiopathic recurrent epistaxis responded to topical treatments. About 0.2% were refractory (20/9239), and 90% of those (18/20) resolved with either a traditional septoplasty (14/20) or modified septoplasty (6/20) without cartilage excision, with a mean follow-up of 35 months. One of the patients who did not show resolution was found to have Von Willebrand disease, which likely contributed to this outcome. Septoplasty surgery, with or without cartilage removal, appears beneficial for refractory idiopathic epistaxis in children. 4 Laryngoscope, 126:2833-2837, 2016. © 2016 The American Laryngological, Rhinological and Otological Society, Inc.

2017-11-01

Full Text Available Abstract Background A large number of studies about adolescents with idiopathic scoliosis focus on health-related quality of life (HRQOL. However, only a few articles aim at evaluating the personality of these patients. Therefore, the purpose of the present research is to assess the personality traits of adolescents with idiopathic scoliosis and their relationship with HRQOL. Our hypothesis is that adolescents with idiopathic scoliosis present the principal personality trait of introversion, defined as self-reliance and inhibition in social relationships. Methods This was a cross-sectional study. The examined group consisted of 43 patients (only 4 boys, mean age = 14.3 (SD = 2.23. On the day of the visit, HRQOL tools (Scoliosis Research Society-22 Questionnaire (SRS-22 and Trunk Appearance Perception Scale (TAPS and a personality test (16 Personality Factors-Adolescent Personality Questionnaire (16PF-APQ were completed; in addition, a posterior-anterior radiography was performed. Correlations among demographic and medical data and HRQOL and personality tests were assessed. Results Results for SRS-22 were as follows: Function 4.5 (SD = .4, Pain 4.3 (SD = .5, Self-image 3.6 (SD = .7, Mental Health 3.8. (SD = .7, and Subtotal 4.2 (SD = .7. Mean TAPS was 3.5 (SD = .6. In personality, the lowest values were assessed for Extroversion (M = 29.4, SD = 24.7 and Self-reliance (M = 71, SD = 25.3. Independence was negatively related to Self-image (r = −.51, Mental Health (r = −.54, and Subtotal SRS-22 (r = −.60 (p < .01. Conclusions Adolescents with idiopathic scoliosis presented a common style of personality, characterized by social inhibition (introversion, preference for staying alone, and being self-sufficient (self-reliance. Specific programs in promoting social abilities may help adolescent patients with idiopathic scoliosis in finding a way to express themselves and to become more sociable. Correlational studies

The purpose of this study was to correlate imaging and sialendoscopic findings to therapeutic response in patients with idiopathic chronic parotitis. We retrospectively reviewed 122 consecutive sialendoscopies performed in an academic medical center by two surgeons between 2008 and 2013. Forty-one (34%) and 54 (44%) patients were excluded on the basis of having parotid or submandibular sialolith, respectively. Nineteen cases were included in the study with idiopathic chronic parotitis. There was a median follow-up of 5 months. Computed tomography (CT) imaging had a sensitivity and specificity of 80.0 and 71.4%, respectively, for predicting abnormal findings on sialendoscopy, while magnetic resonance imaging (MRI) had 100% accuracy in a small set of cases. In glands with noticeable pathology present on preoperative imaging or sialendoscopy, 11 out of 12 glands (92%) treated experienced symptomatic improvement, while 3 out of 7 glands (43%) without pathology on imaging or endoscopy experienced symptomatic improvement (p = 0.038). Sialendoscopy for the treatment of idiopathic chronic parotid disease can improve pain and swelling with a higher frequency of success in patients with abnormalities noted on endoscopy. CT and MRI have a moderate degree of accuracy in predicting which patients will benefit from therapeutic sialendoscopy. © 2015 S. Karger AG, Basel.

Pereira, E A C; Oxenham, M; Lam, K S

2017-06-01

In the United Kingdom, lower incidences of intraspinal abnormalities in patients with early onset idiopathic scoliosis have been observed than in studies in other countries. We aimed to determine the rates of these abnormalities in United Kingdom patients diagnosed with idiopathic scoliosis before the age of 11 years. This retrospective study of patients attending an urban scoliosis clinic identified 71 patients satisfying a criteria of: clinical diagnosis of idiopathic scoliosis; age of onset ten years and 11 months or less; MRI screening for intraspinal abnormalities. United Kingdom census data combined with patient referral data was used to calculate incidence. Mean age at diagnosis was six years with 39 right-sided and 32 left-sided curves. Four patients (5.6%) were found to have intraspinal abnormalities on MRI. These consisted of: two combined Arnold-Chiari type 1 malformations with syrinx; one syrinx with a low lying conus; and one isolated syrinx. Overall annual incidence of early onset idiopathic scoliosis was one out of 182 000 (0.0006%). This study reports the lowest rates to date of intraspinal anomalies in patients with early onset idiopathic scoliosis, adding to knowledge regarding current incidences of these abnormalities as well as any geographical variation in the nature of the disease.

Objective was to discuss the clinical and radiological features and treatment approaches in 14 patients diagnosed with idiopathic granulomatous mastitis (GM). We retrospectively evaluated the clinical features, radiological findings and treatment approaches in 14 patients with idiopathic GM in the General Surgery Department, Gulhane School of Medicine, Ankara, Turkey between April 2000 and June 2006. The mean age of the patients was 34.5 years (range 27-41 years). The complaints at admission were a mass in the breast in 7 (50%) patients, an abscess and a mass in 6 (42.8%) and a skin fisculain one (7.2%). Granulomatous mastitis was unilateral in all subjects (on the right in 5 patients and on the left in 9). All of the patients underwent ultrasonographic evaluation. Mammography was performed in 8 and magnetic resonance imaging in 5 patients. Seven patients (50%) were suspected to have breast carcinoma according radiological findings. We performed the large excision in 11, incisional biopsy plus abscess drainage in one, and incisional biopsy plus abscess drainage plus medical treatment (prednisolone, methotrexate) in 2 patients. Due to the development of abscess after 9 months, drainage and large excision were performed in one patient who received medical treatment. Idiopathic GM is a disease that generally affects young women of reproductive age and may be mistaken for breast carcinoma in clinical and radiological evaluations. The gold standard for the diagnosis is histopathologic evaluation. (author)

Full Text Available Background. There have been inconsistent reports on the prevalence and pathogenicity of anti-Aquaporin 4 (AQP4 in patients presented with idiopathic inflammatory demyelinating diseases (IIDDs. Objective. To estimate the prevalence of anti-AQP4 antibody in patients with IIDDs presented to University Malaya Medical Centre in terms of patients’ clinical and radiological presentations and prognoses. Methods. Retrospective data review of IIDDs patients presented from 2005 to 2015. Patients were classified into classical multiple sclerosis (CMS, opticospinal (OS presentation, optic neuritis (ON, transverse myelitis (TM, brainstem syndrome (BS, and tumefactive MS. Anti-Aquaporin 4 antibody was tested using the Indirect Immunofluorescence Test (IIFT cell-based assay. Statistical analysis was done using the SPSS version 20. Results. Anti-AQP4 antibody was detected in 53% of patients presented with IIDDs. CMS was more common in the seronegative group, 27/47 (57.45%; p<0.001. Conversely, OS involvement was more common in the seropositive group, 26/53 (49.06%; p<0.001. Longitudinally extensive spinal cord lesions (LESCLs on MRI were also more common in the seropositive group, 29/40 (72.50%; p=0.004. Only 2/40 (5.00% had MRI evidence of patchy or multiple short-segment spinal cord lesions in the AQP4-positive group (p=0.003. The relapse rate and Expanded Disability Status Scale (EDSS were also higher in the seropositive group (5.43 versus 3.17, p=0.005; 4.07 versus 2.51, p=0.006, resp.. Typical clinical presentations that defined NMO were also seen in the seronegative patients, but in a lower frequency. Conclusion. Our cohort of patients had a higher prevalence of seropositivity of anti-AQP4 antibody as compared to those in Western countries. This was also associated with a more typical presentation of opticospinal involvement with LESCLs on MRI, a higher rate of relapse, and EDSS.

To investigate the relationship between idiopathic recurrent miscarriage and a polymorphism of the gene encoding for angiopoietin-2 (ANGPT2), an autochthonous modulator of angiogenesis during pregnancy. Prospective case control study. Academic research institution. One hundred thirty-one women with a history of three or more consecutive pregnancy losses before 20 weeks' gestation, and 125 healthy, postmenopausal controls with at least two live births and no history of pregnancy loss. Peripheral venous puncture. Polymerase chain reaction and restriction fragment length polymorphism analysis were performed to identify the different ANGPT2 alleles. No association between mutant (mt) allele and the occurrence of idiopathic recurrent miscarriage was found. Between women with primary and secondary idiopathic recurrent miscarriage, no statistically significant differences with respect to allele frequencies were observed. This is the first report on the ANGPT2 gene polymorphism in women with idiopathic recurrent miscarriage, demonstrating that the investigated polymorphism is not associated with idiopathic recurrent miscarriage in a white population.

There have been no reports describing acute exacerbations of idiopathic pulmonary fibrosis after particle radiotherapy for non-small cell lung cancer. The present study describes the case of a 76-year-old Japanese man with squamous cell carcinoma of the lung that relapsed in the left upper lobe 1 year after right upper lobectomy. He had been treated with oral prednisolone 20 mg/day every 2 days for idiopathic pulmonary fibrosis, and the relapsed lung cancer was treated by proton beam therapy, which was expected to cause the least adverse effects on the idiopathic pulmonary fibrosis. Fifteen days after the initiation of proton beam therapy, the idiopathic pulmonary fibrosis exacerbated, centered on the left upper lobe, for which intensive steroid therapy was given. About 3 months later, the acute exacerbation of idiopathic pulmonary fibrosis had improved, and the relapsed lung cancer became undetectable. Clinicians should be aware that an acute exacerbation of idiopathic pulmonary fibrosis may occur even in proton beam therapy, although proton beam therapy appears to be an effective treatment option for patients with idiopathic pulmonary fibrosis.

Full Text Available Chronic myeloproliferative disorders (CMPD are rarest hematological disorders (malignant myeloid neoplasms. The three most common chronic myeloproliferative disorders are polycythemia vera, essential thrombocythemia and chronic idiopathic myelofibrosis. Clinical manifestations (including oral manifestations of these disorders are overlapping with each other and with other hematologic disorders, which makes the diagnosis of CMPD a challenging task. In this article we report a rare to rarest case of CMPD at dental outpatient department, its oral manifestations and its management in dental clinics.

Idiopathic Noncirrhotic Portal Hypertension: An Appraisal

Lee, Hwajeong; Rehman, Aseeb Ur; Fiel, M. Isabel

2016-01-01

Idiopathic noncirrhotic portal hypertension is a poorly defined clinical condition of unknown etiology. Patients present with signs and symptoms of portal hypertension without evidence of cirrhosis. The disease course appears to be indolent and benign with an overall better outcome than cirrhosis, as long as the complications of portal hypertension are properly managed. This condition has been recognized in different parts of the world in diverse ethnic groups with variable risk factors, resulting in numerous terminologies and lack of standardized diagnostic criteria. Therefore, although the diagnosis of idiopathic noncirrhotic portal hypertension requires clinical exclusion of other conditions that can cause portal hypertension and histopathologic confirmation, this entity is under-recognized clinically as well as pathologically. Recent studies have demonstrated that variable histopathologic entities with different terms likely represent a histologic spectrum of a single entity of which obliterative portal venopathy might be an underlying pathogenesis. This perception calls for standardization of the nomenclature and formulation of widely accepted diagnostic criteria, which will facilitate easier recognition of this disorder and will highlight awareness of this entity.

Acute exacerbation of idiopathic pulmonary fibrosis triggered by Aspergillus empyema

Directory of Open Access Journals (Sweden)

Atsushi Suzuki

Full Text Available Acute exacerbation (AE is a severe and life-threatening complication of idiopathic pulmonary fibrosis (IPF. In 2016, the definition and diagnostic criteria for AE-IPF were updated by an international working group. The new definition includes any acute, clinically significant respiratory deterioration (both idiopathic and triggered events characterized by evidence of new widespread alveolar abnormality in patients with IPF. There are no currently proven beneficial management strategies for idiopathic and triggered AE-IPF. This is the first report describing AE-IPF triggered by Aspergillus empyema, which was improved by a combination of corticosteroid, systemic antifungal therapy, local antifungal therapy, and additional pharmacological therapies. Future research may reveal optimal strategies for both idiopathic and triggered AE-IPF. Keywords: Idiopathic pulmonary fibrosis, Acute exacerbation, AE-IPF, Triggered AE, Aspergillus infection

Objective: To describe the experience with liver irradiation in advanced cases of myelofibrosis with myeloid metaplasia (MMM). Methods: Over a 20-yr period, 14 patients with MMM were treated with a total of 25 courses of liver, abdominal, or abdominal and pelvic irradiation for symptomatic hepatomegaly with (5 patients) or without (9 patients) ascites. All 14 patients had advanced disease and 11 (79%) had previous splenectomy. The median radiation therapy (RT) dose per course was 150 cGy (range 50-1000) administered at a median of six fractions. Four patients received two to six courses. Results. Twelve of the 14 patients (86%) had a transient (median 3 months) subjective response from RT. However, in only 35% of these was there a transient (median 3 months) decrease in palpable liver size. Four of the five patients with ascites experienced a short-term response from RT. Eight of the 13 patients suitable for evaluation (62%) had treatment-associated cytopenia, often in the form of anemia and/or thrombocytopenia. At last follow-up, 10 patients (71%) had died after a median of 7 months (range 0.1-23) and 4 were alive at 3, 20, 33, and 57 months after RT. Conclusions: Low-dose abdominal RT for symptomatic hepatomegaly or ascites associated with advanced-stage MMM is myelosuppressive and provides only temporary and mainly subjective and short-lived relief.

It is unknown if uni- or bilateral lung transplant is best for treatment of usual idiopathic pulmonary fibrosis. We reviewed our single-center experience comparing both treatments. Between 2002 and 2011, one hundred thirty-eight patients at our institution underwent a lung transplant. Of these, 58 patients presented with idiopathic pulmonary fibrosis (56.9%) and were the focus of this study. Thirty-nine patients received a single lung transplant and 19 patients a bilateral sequential lung transplant. The mean patient age was 54 ± 10 years, and 69% were male. The intraoperative course was uneventful, save for 7 patients who needed extracorporeal membrane oxygenation support. Three patients had respiratory failure before the lung transplant that required mechanical ventilation and was supported by extracorporeal membrane oxygenation. Elevated pulmonary artery pressure > 40 mm Hg was identified as an independent predictor of early mortality by uni- and multivariate analysis (P = .01; OR 9.7). Using a Cox regression analysis, postoperative extracorporeal membrane oxyge-nation therapy (P = .01; OR 10.2) and the need for > 10 red blood cell concentrate during the first 72 hours after lung transplant (P = .01; OR 5.6) were independent predictors of long-term survival. Actuarial survival at 1 and 5 years was 65.6% and 55.3%, with no significant between-group differences (70.6% and 54.3%). Lung transplant is a safe and curative treatment for idiopathic pulmonary fibrosis. According to our results, unilateral lung transplant for idiopathic pulmonary fibrosis is an alternative to bilateral lung transplant and may affect the allocation process.

CSF volumes in the basal cistern and Sylvian fissure are increased in both idiopathic normal pressure hydrocephalus and Alzheimer disease, though the differences in these volumes in idiopathic normal pressure hydrocephalus and Alzheimer disease have not been well-described. Using CSF segmentation and volume quantification, we compared the distribution of CSF in idiopathic normal pressure hydrocephalus and Alzheimer disease. CSF volumes were extracted from T2-weighted 3D spin-echo sequences on 3T MR imaging and quantified semi-automatically. We compared the volumes and ratios of the ventricles and subarachnoid spaces after classification in 30 patients diagnosed with idiopathic normal pressure hydrocephalus, 10 with concurrent idiopathic normal pressure hydrocephalus and Alzheimer disease, 18 with Alzheimer disease, and 26 control subjects 60 years of age or older. Brain to ventricle ratios at the anterior and posterior commissure levels and 3D volumetric convexity cistern to ventricle ratios were useful indices for the differential diagnosis of idiopathic normal pressure hydrocephalus or idiopathic normal pressure hydrocephalus with Alzheimer disease from Alzheimer disease, similar to the z-Evans index and callosal angle. The most distinctive characteristics of the CSF distribution in idiopathic normal pressure hydrocephalus were small convexity subarachnoid spaces and the large volume of the basal cistern and Sylvian fissure. The distribution of the subarachnoid spaces in the idiopathic normal pressure hydrocephalus with Alzheimer disease group was the most deformed among these 3 groups, though the mean ventricular volume of the idiopathic normal pressure hydrocephalus with Alzheimer disease group was intermediate between that of the idiopathic normal pressure hydrocephalus and Alzheimer disease groups. The z-axial expansion of the lateral ventricle and compression of the brain just above the ventricle were the common findings in the parameters for differentiating

JAK2V617F mutation in a patient with B-cell chronic lymphocytic leukemia and prefibrotic primary myelofibrosis

2015-01-01

Full Text Available Introduction. Secondary malignancies, particularly solid tumors, are common in patients with chronic lymphocytic leukemia (CLL, but association of myeloproliferative neoplasms and chronic lymphocytic leukemia in the same patient is very rare. Case Outline. We report of a 67-year-old man with B-cell chronic lymphoid leukemia (B-CLL who developed primary myelofibrosis (PMF nine years after initial diagnosis. Patient received alkylation agents and purine analogue, which can be a predisposing factor for the development of myeloproliferative neoplasms. JAK2V617F mutation was not present initially at the time of CLL diagnosis, but was found after nine years when PMF occurred, which indicates that B-CLL and PMF represent two separate clonal origin neoplasms. Conclusion. Pathogenic mechanisms for the development of myeloproliferative and lymphoproliferative neoplasms in the same patient are unknown. Further research is needed to determine whether these malignancies originate from two different cell clones or arise from the same pluripotent hematopoietic stem cell.

Sun Bean Kim

2015-12-01

Full Text Available Peliosis hepatis is a rare condition that can cause hepatic hemorrhage, rupture, and ultimately liver failure. Several authors have reported that peliosis hepatis develops in association with chronic wasting disease or prolonged use of anabolic steroids or oral contraceptives. In this report we describe a case in which discontinuation of steroid therapy improved the condition of a patient with peliosis hepatis. Our patient was a 64-year-old woman with a history of long-term steroid treatment for idiopathic thrombocytopenic purpura . Her symptoms included abdominal pain and weight loss; the only finding of a physical examination was hepatomegaly. We performed computed tomography (CT and magnetic resonance imaging (MRI of the liver and a liver biopsy. Based on these findings plus clinical observations, she was diagnosed with peliosis hepatis and her steroid treatment was terminated. The patient recovered completely 3 months after steroid discontinuation, and remained stable over the following 6 months.

Transcriptome analysis of bone marrow mesenchymal stromal cells from patients with primary myelofibrosis

Directory of Open Access Journals (Sweden)

Christophe Martinaud

2015-09-01

Full Text Available Primary myelofibrosis (PMF is a clonal myeloproliferative neoplasm whose severity and treatment complexity are attributed to the presence of bone marrow (BM fibrosis and alterations of stroma impairing the production of normal blood cells. Despite the recently discovered mutations including the JAK2V617F mutation in about half of patients, the primitive event responsible for the clonal proliferation is still unknown. In the highly inflammatory context of PMF, the presence of fibrosis associated with a neoangiogenesis and an osteosclerosis concomitant to the myeloproliferation and to the increase number of circulating hematopoietic progenitors suggests that the crosstalk between hematopoietic and stromal cells is deregulated in the PMF BM microenvironmental niches. Within these niches, mesenchymal stromal cells (BM-MSC play a hematopoietic supportive role in the production of growth factors and extracellular matrix which regulate the proliferation, differentiation, adhesion and migration of hematopoietic stem/progenitor cells. A transcriptome analysis of BM-MSC in PMF patients will help to characterize their molecular alterations and to understand their involvement in the hematopoietic stem/progenitor cell deregulation that features PMF.

Nephrotic syndrome in primary myelofibrosis with renal extramedullary hematopoiesis and glomerulopathy in the JAK inhibitor era.

Primary myelofibrosis (PMF) is an uncommon form of myeloproliferative neoplasm (MPN) characterized by a proliferation of predominantly megakaryocytes and granulocytes in the bone marrow that, in fully-developed disease, is associated with reactive deposition of fibrous connective tissue, extramedullary hematopoiesis (EMH), and splenomegaly. Kidney involvement is rare and clinically presents with proteinuria, nephrotic syndrome, and renal insufficiency. Renal damage can be due to EMH and glomerulopathy. Renal EMH presents three patterns: infiltration of the interstitium with possible renal failure caused by functional damage of parenchyma and vessels, infiltration of capsule and pericapsular adipose tissue, and sclerosing mass-like lesions that can cause hydronephrosis and hydroureter with obstructive uropathy and renal failure. Glomerulopathy associated with PMF is rarely described, ranging from 1 month to 18 years from diagnosis of the neoplasm to renal biopsy. It is characterized by expansion and hypercellularity mesangial, segmental sclerosis, features of chronic thrombotic microangiopathy (TMA), and intracapillary hematopoietic cells infiltrating in absence of immune-mediated glomerulonephritis. We present a nephrotic syndrome in PMF-related glomerulopathy, associated with EMH, without renal failure, in a patient under treatment for 2 years with JAK2 inhibitor ruxolitinib. Despite treatment, the patient died 7 months after renal biopsy. Nephrologists still know very little about this topic and there is no homogeneous data about incidence, pathogenesis, and optimal treatment of this poor prognostic PMF-associated nephrotic syndrome. We focus on data in the literature in the hope of stimulating hematologists, nephrologists, pathologists to future studies about the natural history of renal involvement, useful for optimal management of this rare pathology.

Full Text Available The idiopathic interstitial pneumonias (IIPs are a heterogeneous group of rare interstitial lung diseases (ILDs or diffuse parenchymal lung diseases, which, as their name implies, are of unknown aetiology. The past 10 yrs have seen important advances in the classification of the IIPs into idiopathic pulmonary fibrosis (IPF and its corresponding histopathological pattern of usual interstitial pneumonia (UIP, plus six non-IPF IIP subtypes. The present article will look at the current classification of IIPs, arising from the Consensus Statement of the American Thoracic Society and European Respiratory Society, and discusses the importance of differential diagnosis of IPF from the non-IPF IIP subtypes, especially nonspecific interstitial pneumonia. Diagnosis of IIPs is a dynamic process involving close collaboration between pulmonologists, radiologists and pathologists. Increasingly accurate diagnosis of IPF has been made possible by the use of high-resolution computed tomography (HRCT and refinements in surgical lung biopsy. In IPF, a lung HRCT will typically reveal irregular reticular opacities, traction bronchiestasis and, most importantly, peripheral honeycombing. In contrast, histological examination shows evidence of UIP manifesting as typically subpleural and paraseptal established fibrosis, often with honeycomb changes, associated with mild chronic inflammation and varying numbers of fibroblastic foci in continuity with the edges of areas of established fibrosis. Despite these advances, obtaining a consistent and uniform diagnosis of idiopathic interstitial pneumonias is difficult, with studies showing significant disagreement in the diagnosis of interstitial lung diseases between academic centres of expertise and community-based clinicians. Greater interaction between academic and community clinicians, together with improved education, is needed to bridge this gap.

Discrete potentials (DPs) have been recorded and targeted as the site of ablation of the outflow tract arrhythmias. The aim of the present study was to investigate the significance of DPs with respect to mapping and ablation for idiopathic outflow tract premature ventricular contractions (PVCs) or ventricular tachycardias (VTs). Seventeen consecutive patients with idiopathic right or left ventricular outflow tract PVCs/VTs who underwent radiofrequency catheter ablation were included. Intracardiac electrograms during the mapping and ablation were analysed. During sinus rhythm, sharp high-frequency DPs that displayed double or multiple components were recorded following or buried in the local ventricular electrograms in all of the 17 patients, peak amplitude 0.51 ± 0.21 mV. The same potential was recorded prior to the local ventricular potential of the PVCs/VTs. Spontaneous reversal of the relationship of the DPs to the local ventricular electrogram during the arrhythmias was noted. The DPs were related to a region of low voltage showed by intracardiac high-density contact mapping. At the sites with DPs, lower unipolar and bipolar ventricular voltage of sinus beats were noted compared with the adjacent regions without DPs (unipolar: 6.1 ± 1.8 vs. 8.3 ± 2.3 mV, P Discrete potentials were not present in seven controls. Discrete potentials and related low-voltage regions were common in idiopathic outflow tract ventricular arrhythmias. Discrete potential- and substrate-guided ablation strategy will help to reduce the recurrence of idiopathic outflow tract arrhythmias. Published on behalf of the European Society of Cardiology.

Pathology of idiopathic non-cirrhotic portal hypertension.

Guido, Maria; Sarcognato, Samantha; Sacchi, Diana; Colloredo, Guido

2018-04-12

Idiopathic non-cirrhotic portal hypertension is an under-recognized vascular liver disease of unknown etiology, characterized by clinical signs of portal hypertension in the absence of cirrhosis. By definition, any disorder known to cause portal hypertension in the absence of cirrhosis and any cause of chronic liver disease must be excluded to make a diagnosis of idiopathic non-cirrhotic portal hypertension. However, the diagnosis is often difficult because the disease resembles cirrhosis and there is no gold standard test. Liver biopsy is an essential tool: it is able to exclude cirrhosis and other causes of portal hypertension and it allows the identification of the characteristic lesions. Nonetheless, the histological diagnosis of idiopathic non-cirrhotic portal hypertension is not always straightforward, in particular by needle biopsy samples, because there is no pathognomonic lesion, but rather a variety of vascular changes which are unevenly distributed, very subtle, and not all necessarily identified in a single specimen. Pathologists should be able to recognize several patterns of injury, involving portal/periportal areas as well as parenchymal structures.The histological features of idiopathic non-cirrhotic portal hypertension are described in this review, focusing on their interpretation in needle biopsy specimens.

Purpose: To compare clinical and computed tomography (CT) measures in extension, 20 o and 30 o of flexion of symptomatic knees of patient with idiopathic patellofemoral pain syndrome with the contra lateral asymptomatic knee. Materials and methods: Knees of 52 consecutive patients with idiopathic patellofemoral pain were studied with CT. In 28 patients this condition was unilateral and asymptomatic knee was used as control; 76 knees were symptomatic. Results: In patients with idiopathic patellofemoral pain we found a greater Q angle and internal condylar facet width in symptomatic knees with regard to asymptomatic knees. Conclusion: Greater Q angle and medial condylar facet can lead to overpressure on the medial knee compartment during maneuvers that increase contact between patella and medial condylar facet, such as knee flexion and squatting, contributing to development of idiopathic patellofemoral pain.

Idiopathic scoliosis is a three-dimensional deformity of the growing spine, affecting 2%–3% of adolescents. Although benign in the majority of patients, the natural course of the disease may result in significant disturbance of body morphology, reduced thoracic volume, impaired respiration, increased rates of back pain, and serious esthetic concerns. Risk of deterioration is highest during the pubertal growth spurt and increases the risk of pathologic spinal curvature, increasing angular value, trunk imbalance, and thoracic deformity. Early clinical detection of scoliosis relies on careful examination of trunk shape and is subject to screening programs in some regions. Treatment options are physiotherapy, corrective bracing, or surgery for mild, moderate, or severe scoliosis, respectively, with both the actual degree of deformity and prognosis being taken into account. Physiotherapy used in mild idiopathic scoliosis comprises general training of the trunk musculature and physical capacity, while specific physiotherapeutic techniques aim to address the spinal curvature itself, attempting to achieve self-correction with active trunk movements developed in a three-dimensional space by an instructed adolescent under visual and proprioceptive control. Moderate but progressive idiopathic scoliosis in skeletally immature adolescents can be successfully halted using a corrective brace which has to be worn full time for several months or until skeletal maturity, and is able to prevent more severe deformity and avoid the need for surgical treatment. Surgery is the treatment of choice for severe idiopathic scoliosis which is rapidly progressive, with early onset, late diagnosis, and neglected or failed conservative treatment. The psychologic impact of idiopathic scoliosis, a chronic disease occurring in the psychologically fragile period of adolescence, is important because of its body distorting character and the onerous treatment required, either conservative or surgical

Adolescent idiopathic scoliosis: Indications and efficacy of nonoperative treatment

Directory of Open Access Journals (Sweden)

Federico Canavese

2011-01-01

Full Text Available The strategy for the treatment of idiopathic scoliosis depends essentially upon the magnitude and pattern of the deformity, and its potential for progression. Treatment options include observation, bracing and/or surgery. During the past decade, several studies have demonstrated that the natural history of adolescent idiopathic scoliosis can be positively affected by nonoperative treatment, especially bracing. Other forms of conservative treatment, such as chiropractic or osteopathic manipulation, acupuncture, exercise or other manual treatments, or diet and nutrition, have not yet been proven to be effective in controlling spinal deformity progression, and those with a natural history that is favorable at the completion of growth. Observation is appropriate treatment for small curves, curves that are at low risk of progression, and those with a natural history that is favorable at the completion of growth. Indications for brace treatment are a growing child presenting with a curve of 25°-40° or a curve less than 25° with documented progression. Curves of 20°-25° in patients with pronounced skeletal immaturity should also be treated. The purpose of this review is to provide information about conservative treatment of adolescent idiopathic scoliosis. Indications for conservative treatment, hours daily wear and complications of brace treatment as well as brace types are discussed.

Full Text Available Introduction. JAK2V617F mutation is detected in approximately 50 % of patients with essential thrombocytosis (ET and primary myelofibrosis (PMF. In 2013 most of the JAK2 negative patients showed mutations in the CALR gene. Diagnostic value of JAK2 and CALR mutations is high, but their prognostic significance is not sufficiently clear. Data on impact of JAK2 and CALR mutational status on thrombotic complications in ET and myelofibrosis patients are contradictory.The aim of the study was to identify clinical and laboratory features in patients with ET and PMF in accordance with the mutational status of JAK2V617F and CALR gene.Materials and methods. Patients treated in Almazov National Medical Research Center (St. Petersburg, Chuvash Republican Clinical Hospital (Cheboksary, Irkutsk Regional Clinical Hospital (Irkutsk,  Kirov Research Institute of Hematology and Blood Transfusion (Kirov was included in the retrospective study. CALR mutation (1 and 2 types, MPL W515L/K and JAK2V617F mutation were detected in peripheral blood cells.Results. We identified that 21 % (n = 16 of ET patients had thrombotic complications, and they occurred more often among JAK2V617F positive patients (p <0.05. The median of hemoglobin level in PMF was the lowest in the group of triple negative patients. The level of leukocytes in PMF was higher in the group of triple negative patients than in the group with mutated CALR (p = 0.014.Conclusion. JAK2V617F mutation in ET patients was associated with a high risk of thrombosis. Patients with CALR mutations may have a favorable prognosis regarding to thrombotic complications. Some laboratory features of CALR mutations in ET and PMF patients have been revealed.

Scoliosis is a three-dimensional deformation of the spine with a lateral curvature or deviation greater than 10 degrees and associated with vertebral rotation. Many conservative treatments are available for adolescents with idiopathic scoliosis, but the evidence for their effectiveness is still questioned. The objective of this study was to define the effectiveness of braces and individual physiotherapy for the comprehensive treatment of idiopathic scoliosis in adolescents. A retrospective study of 57 children with idiopathic thoracic dextroscoliosis with the magnitude of the thoracic curve between 20 degrees-35 degrees, treated in Orthopedic and Physiatrist Clinic as well as National Ortho-prosthetic Center within University Clinical Center of Kosova in Prishtina, during the period of 2003-2006. Inclusion of kinesitherapy in the comprehensive management of idiopathic scoliosis varied in the improvement of the muscle strength (satisfied and moderate) in almost 80% of the children while the correction of the curve was small in approximately 42.1% of cases. For children with idiopathic scoliosis, who require braces, an exercise program helps chest mobility, muscle strength, proper breathing flexibility in the spine, correct posture and keeps muscles in tone so that the transition period after brace removal is easier.

Idiopathic pulmonary fibrosis is defined as chronic fibrosing interstitial pneumonia limited to the lung, with poor prognosis. The incidence has been rising in recent years probably due to improved diagnostic methods and increased life expectancy. In 2013, the SEPAR guidelines for the diagnosis and treatment for idiopathic pulmonary fibrosis were published. Since then, clinical trials and meta-analyses have shown strong scientific evidence for the use of pirfenidone and nintedanib in the treatment of idiopathic pulmonary fibrosis. In 2015, the international consensus of 2011 was updated and new therapeutic recommendations were established, prompting us to update our recommendation for the medical treatment of idiopathic pulmonary fibrosis accordingly. Diagnostic aspects and non-pharmacological treatment will not be discussed as no relevant developments have emerged since the 2013 guidelines. Copyright © 2017 SEPAR.

Idiopathic diaphragmatic paralysis: Bell's palsy of the diaphragm?

Crausman, Robert S; Summerhill, Eleanor M; McCool, F Dennis

2009-01-01

Idiopathic diaphragm paralysis is probably more common and responsible for more morbidity than generally appreciated. Bell's palsy, or idiopathic paralysis of the seventh cranial nerve, may be seen as an analogous condition. The roles of zoster sine herpete and herpes simplex have increasingly been recognized in Bell's palsy, and there are some data to suggest that antiviral therapy is a useful adjunct to steroid therapy. Thus, we postulated that antiviral therapy might have a positive impact on the course of acute idiopathic diaphragm paralysis which is likely related to viral infection. Three consecutive patients with subacute onset of symptomatic idiopathic hemidiaphragm paralysis were empirically treated with valacyclovir, 1,000 mg twice daily for 1 week. Prior to therapy, diaphragmatic function was assessed via pulmonary function testing and two-dimensional B-mode ultrasound, with testing repeated 1 month later. Diaphragmatic function pre- and post-treatment was compared to that of a historical control group of 16 untreated patients. All three subjects demonstrated ultrasound recovery of diaphragm function 4-6 weeks following treatment with valacyclovir. This recovery was accompanied by improvements in maximum inspiratory pressure (PI(max)) and vital capacity (VC). In contrast, in the untreated cohort, diaphragm recovery occurred in only 11 subjects, taking an average of 14.9 +/- 6.1 months (mean +/- SD). The results of this small, preliminary study suggest that antiviral therapy with valacyclovir may be helpful in the treatment of idiopathic diaphragm paralysis induced by a viral infection.

2007-01-01

The Philadelphia chromosome (Ph)-negative myeloproliferative disorders (MPDs) include essential thrombocythemia (ET), idiopathic myelofibrosis (IMF), and polycythemia vera (PV). All of these disorders are clonal hematologic malignancies originating at the level of the pluripotent hematopoietic stem cell. Recently, activating mutations of the intracellular cytokine-signaling molecule JAK2 have been identified in > 90% of patients with PV and in 50% of those with IMF and ET. In addition, a mutation of the thrombopoietin receptor, MPLW515L, has been documented in some patients with IMF. Both mutations activate JAK-STAT signaling pathways and likely play a role in disease progression. Both ET and PV are associated with prolonged clinical courses associated with frequent thrombotic and hemorrhagic events, and progression to myelofibrosis and acute leukemia. IMF has a much poorer prognosis and is associated with cytopenias, splenomegaly, extramedullary hematopoiesis, and bone marrow fibrosis. Stratification of risk for the development of complications from Ph-negative MPDs has guided the identification of appropriate therapies for this population. Intermediate/high-risk IMF or myelofibrosis after ET or PV is associated with a sufficiently poor prognosis to justify the use of allogeneic stem cell transplantation, which is capable of curing such patients. Reduced-intensity conditioning in preparation for allogeneic stem cell transplantation has permitted older patients with IMF to undergo transplantation with increasing success.

2008-01-01

The prevalence of idiopathic normal-pressure hydrocephalus (NPH) in a community was investigated by retrospective analysis of data from a previous community-based study of 170 randomly selected elderly residents aged 65 years or older. Magnetic resonance (MR) images of the subjects were reviewed for the specific structural features of idiopathic NPH, i.e. ventricular enlargement and narrow cerebrospinal fluid (CSF) space at high convexity and high midline areas. The clinical features of idiopathic NPH, gait disturbance, urinary incontinence, and cognitive impairment, were evaluated on the basis of records of the subjects' neurological examinations, a health questionnaire, the Mini-Mental State Examination, and Clinical Dementia Rating. Thirteen of the 170 subjects showed lateral ventricular enlargement greater than 0.3 on Evans' index. Five subjects (2.9%) demonstrated both ventricular enlargement and narrow CSF space at the high convexity/midline. All five subjects with these MR imaging signs had cognitive impairment, one had gait disturbance, and one had urinary incontinence. The present study found 2.9% of community-dwelling elderly subjects showed radiological and clinical features consistent with idiopathic NPH. (author)

Full Text Available Cryptogenic Organising Pneumonia (COP, also called idiopathic Bronchiolitis Obliterans Organising Pneumonia( BOOP, is a distinct entity among the idiopathic interstitial pneumonias defined histopathologically by intraalveolar buds of granulation tissue. The etiology includes idiopathic, infectious, drug induced radiation induced and connective tissue diseases. Organising pneumonia occurs particularly in patients with dermatomyositis-polymyositis where it may be the presenting manifestation, and rarely in SLE, rheumatoid arthritis, scleroderma and other connective tissue diseases. We describe a 30 yr old lady who initially presented with respiratory symptoms, not responding to antibiotics. She was subsequently diagnosed as SLE and HRCT thorax showed consolidation involving both lung fields. A percutaneous lung biopsy revealed features of Cryptogenic Organising Pneumonia.

Idiopathic short stature

Vlaški Jovan

Full Text Available Growth is a complex process and the basic characteristic of child- hood growth monitoring provides insight into the physiological and pathological events in the body. Statistically, the short stature means departure from the values of height for age and sex (in a particular environment, which is below -2 standard deviation score, or less than -2 standard deviation, i.e. below the third percentile. Advances in molecular genetics have contributed to the improvement of diagnostics in endocrinology. Analysis of patients’ genotypes should not be performed before taking a classical history, detailed clinical examination and appropriate tests. In patients with idiopathic short stature specific causes are excluded, such as growth hormone deficiency, Turner syndrome, short stature due to low birth weight, intrauterine growth retardation, small for gestational age, dysmorphology syndromes and chronic childhood diseases. The exclusion of abovementioned conditions leaves a large number of children with short stature whose etiology includes patients with genetic short stature or familial short stature and those who are low in relation to genetic potential, and who could also have some unrecognized endocrine defect. Idiopathic short stature represents a short stature of unknown cause of heterogeneous etiology, and is characterized by a normal response of growth hormone during stimulation tests (>10 ng/ml or 20 mJ/l, without other disorders, of normal body mass and length at birth. In idiopathic short stature standard deviation score rates <-2.25 (-2 to -3 or <1.2 percentile. These are also criteria for the initiation of growth hormone therapy. In children with short stature there is also the presence of psychological and social suffering. Goals of treatment with growth hormone involve achieving normal height and normal growth rate during childhood.

MSLT data and PSG findings from the time of their diagnosis were reviewed. HLA typing was performed. Results Results indicated that the idiopathic hypersomnia group showed a significant longer mean sleep latency in MSLT compared with the narcolepsy without cataplexy group. But there was no significant difference in the Epworth Sleepiness Scale (ESS scores between the two groups. Although HLA positivity of both groups was not statistically significant (p = 0.065, HLA positivity tended to be higher in the narcolepsy without cataplexy group than the idiopathic hypersomnia group. The number of awakenings was slightly higher in the idiopathic hypersomnia group, but there was no statistical significance. The number of spontaneous arousal and total arousal indices was not significantly different between the groups. For the PSG, the idiopathic hypersomnia group showed a significantly longer sleep latency than the narcolepsy without cataplexy group (p = 0.009. REM sleep latency (REML was significantly shorter in the narcolepsy without cataplexy group compared to the idiopathic hypersomnia group. The percentage of REM (SREM was significantly higher in the narcolepsy without cataplexy group, and the percentage of the wake time during sleep period (SWT was significantly lower in the narcolepsy without cataplexy group. Conclusions There were no significant differences of subjective sleep measures such as ESS, disturbed nocturnal sleep, number of naps, age of onset of hypnagogic hallucination, and age of onset of sleep

Scrotal lymphedema (scrotal elephantiasis) is uncommon outside of filariasis endemic regions. We present a case of a 65-year-old with idiopathic lymphedema of the scrotum and functional impairment of the penis. The patient underwent surgical excision of the edematous subcutaneous tissues and plastic reconstruction of his penis and scrotum. Three years later, the patient showed no signs of local recurrence, had complete restoration of urinary and sexual function and was extremely satisfied with the result. Surgical management was an effective strategy in the management of scrotal lymphedema in this case.

Full Text Available Abstract Background Idiopathic membranous nephropathy (IMN is one of the most common causes of primary nephrotic syndrome in adults. However, it is a relatively rare entity in the pediatric population and there is a paucity of data about the incidence, prognosis, and optimal treatment of IMN in children and adolescents. We conducted this study to evaluate pediatric patients with IMN in order to clarify the presentation, response to therapy, and clinical outcome. Methods A retrospective chart review was performed on patients identified with biopsy-proven IMN between 1988–2005. Patients with systemic lupus erythematosus or hepatitis-related lesions were excluded. The following data were tabulated: age, gender, ethnicity, presenting clinical and laboratory findings, proteinuria in a first morning urine specimen, estimated glomerular filtration rate (GFRe, histopathology, type and duration of treatment, and clinical status at final evaluation. Results 13 cases of IMN were identified out of 460 renal biopsies performed for evaluation of primary kidney disease during the study interval. Mean age was 9.6 ± 4.6, gender 6 M:7 F, ethnicity 8 W:2 B:3 H. At the initial visit hematuria was present in 9 patients, edema in 5, nephrotic-range proteinuria in 5, and hypertension in 3. Mean urinary protein:creatinine ratio 3.3 ± 2.5 and all patients had a normal GFRe. Classic glomerular findings of IMN were seen in all renal specimens, with concomitant interstitial changes in 2 cases. Treatment included an angiotensin converting enzyme inhibitor or angiotensin receptor blocker in 11 cases. Most patients were also given immunosuppressive medications – prednisone in 10, a calcineurin inhibitor in 5, and mycophenolate mofetil or azathioprine in 3 patients. At the last follow-up, 42 ± 35 months after the diagnostic biopsy, 7 children were hypertensive and the urine protein:creatinine ratio was 2.3 ± 3.1. The mean GFRe was 127 ± 57 mL/min/m2.

Objectives: Patients with idiopathic pulmonary fibrosis (IPF) have an increased risk of pulmonary tuberculosis. However, detecting pulmonary tuberculosis may be difficult due to the underlying fibrosis. The aim of this report is to describe the radiological and clinical findings of pulmonary tuberculosis in patients with idiopathic pulmonary fibrosis. Materials and methods: We reviewed 143 consecutive patients in whom IPF was diagnosed by either the histological or radio-clinical criteria. Among them, nine patients were histologically (n=2) or bacteriologically (n=7) confirmed to have active pulmonary tuberculosis. The location and patterns of pulmonary tuberculosis were examined on a thin section CT scan. Results: The most common thin section CT findings were subpleural nodules (n=6; mean diameter, 3.2 cm) and a lobar or segmental consolidation (n=3). The lesions were located most commonly in the right lower lobe (n=4). The incidence of tuberculosis in patients with idiopathic pulmonary fibrosis was more than five times higher than that of the general population. Conclusion: The atypical manifestation of pulmonary tuberculosis is common in patients with idiopathic pulmonary fibrosis, which may mimic lung cancer or bacterial pneumonia.

Fahr’s syndrome and idiopathic hypoparathyroidism: A case report

Directory of Open Access Journals (Sweden)

Marinković Dejan M.

2017-01-01

Full Text Available Introduction. Fahr´s syndrome is a rare, slowly progressive, neurodegenerative disorder, characterised by extensive, bilateral, and symmetrical basal ganglia calcification. It is associated with neuropsychiatric manifestations and gradually progressive cognitive impairment. Fahr's syndrome is the secondary form of brain calcification that is caused by various metabolic, infectious, or degenerative diseases. Case report. We presented a middle-aged male with Fahr's syndrome due to primary idiopathic hypoparathyroidism. Clinical diagnosis was based on signs and symptoms of hypocalcemia, progressive neuropsychiatric illnesses, laboratory evidence of hypoparathyroidism, and radiological signs of calcifications in the basal ganglia. The patient improved after only a few days of intravenous rehydration and calcium substitution, followed by oral supplemental calcitriol. Conclusion. Timely recognition of idiopathic and iatrogenic hypoparathyroidism allows appropriate treatment that can prevent the development and clinical manifestations of Fahr´s syndrome and potentially slow its progression.

A protocol to treat idiopathic constipation is presented. A contrast enema is performed in every patient and, when indicated, patients are initially submitted to a "clean out" protocol. All patients are started on a Senna-based laxative. The initial dosage is empirically determined and adjusted daily, during a one week period, based on history and abdominal radiographs, until the amount of Senna that empties the colon is reached. The management is considered successful when patients empty their colon daily and stop soiling. If the laxatives dose provokes abdominal cramping, distension, and vomiting, without producing bowel movements, patients are considered nonmanageable. From 2005 to 2012, 215 patients were treated. 121 (56%) were males. The average age was 8.2years (range: 1-20). 160 patients (74%) presented encopresis. 67 patients (32%) needed a clean out. After one week, 181 patients (84%) achieved successful management, with an average Senna dose of 67mg (range: 5-175mg). In 34 patients (16%) the treatment was unsuccessful: 19 were nonmanageable, 3 noncompliant, and 12 continued soiling. At a later follow-up (median: 329days) the success rate for 174 patients was 81%. We designed a successful protocol to manage idiopathic constipation. The key points are clean out before starting laxatives, individual adjustments of laxative, and radiological monitoring of colonic emptying. Level IV. Copyright © 2017 Elsevier Inc.

2006-02-01

Full Text Available Abstract Background Idiopathic sclerosing encapsulating peritonitis (or abdominal cocoon is a rare cause of small bowel obstruction, especially in adult population. Diagnosis is usually incidental at laparotomy. We discuss one such rare case, outlining the fact that an intra-operative surprise diagnosis could have been facilitated by previous investigations. Case presentation A 56 year-old man presented in A&E department with small bowel ileus. He had a history of 6 similar episodes of small bowel obstruction in the past 4 years, which resolved with conservative treatment. Pre-operative work-up did not reveal any specific etiology. At laparotomy, a fibrous capsule was revealed, in which small bowel loops were encased, with the presence of interloop adhesions. A diagnosis of abdominal cocoon was established and extensive adhesiolysis was performed. The patient had an uneventful recovery and follow-up. Conclusion Idiopathic sclerosing encapsulating peritonitis, although rare, may be the cause of a common surgical emergency such as small bowel ileus, especially in cases with attacks of non-strangulating obstruction in the same individual. A high index of clinical suspicion may be generated by the recurrent character of small bowel ileus combined with relevant imaging findings and lack of other plausible etiologies. Clinicians must rigorously pursue a preoperative diagnosis, as it may prevent a "surprise" upon laparotomy and result in proper management.

To determine whether patients with idiopathic and symptomatic RBD were sleepier than controls, and if sleepiness in idiopathic RBD predicted earlier conversion to Parkinson disease. The Epworth Sleepiness Scale (ESS) and its determinants were compared at the time of a video-polysomnography for an RBD diagnosis in patients with idiopathic RBD, in patients with Parkinson disease, and in controls. Whether sleepiness at time of RBD diagnosis predicted an earlier conversion to neurodegenerative diseases was retrospectively analyzed in the followed-up patients. The 75 patients with idiopathic RBD were sleepier (ESS: 7.8 ± 4.6) at the time of RBD diagnosis than 74 age- and sex-matched controls (ESS: 5.0 ± 3.6, P sleep measures. Among the 69 patients with idiopathic RBD who were followed up for a median 3 years (1-15 years), 16 (23.2%) developed parkinsonism (n = 6), dementia (n = 6), dementia plus parkinsonism (n = 2), and multiple system atrophy (n = 2). An ESS greater than 8 at time of RBD diagnosis predicted a shorter time to phenoconversion to parkinsonism and dementia, from RBD onset, and from RBD diagnosis (when adjusted for age and time between RBD onset and diagnosis). Sleepiness is associated with idiopathic REM sleep behavior disorder and predicts more rapid conversion to parkinsonism and dementia, suggesting it is an early marker of neuronal loss in brainstem arousal systems. © 2015 Associated Professional Sleep Societies, LLC.

To investigate obesity as susceptibility factor in patients with idiopathic AA amyloidosis. Clinical, biochemical and genetic data were obtained from 146 patients with AA amyloidosis. Control groups comprised 40 patients with long-standing inflammatory diseases without AA amyloidosis and 56 controls without any inflammatory disease. Patients with AA amyloidosis had either familial Mediterranean fever (FMF) or long-standing rheumatic diseases as underlying inflammatory disease (n = 111, median age 46 years). However, in a significant proportion of patients with AA amyloidosis no primary disease was identified (idiopathic AA; n = 37, median age 60 years). Patients with idiopathic AA amyloidosis were more obese and older than patients with AA amyloidosis secondary to FMF or rheumatic diseases. Serum leptin levels correlated with the body mass index (BMI) in all types of AA amyloidosis. Elevated leptin levels of more than 30 µg/l were detected in 18% of FMF/rheumatic + AA amyloidosis and in 40% of patients with idiopathic AA amyloidosis (p = .018). Finally, the SAA1 polymorphism was confirmed as a susceptibility factor for AA amyloidosis irrespective of the type of the disease. Obesity, age and the SAA1 polymorphism are susceptibility factors for idiopathic AA amyloidosis. Recent advances in treatment of FMF and rheumatic disorders will decrease the incidence of AA amyloidosis due to these diseases. Idiopathic AA, however, might be an emerging problem in the ageing and increasingly obese population.

To perform a genotype-phenotype correlation study in an X-linked congenital idiopathic nystagmus pedigree (pedigree 1) and to assess the allelic variance of the FRMD7 gene in congenital idiopathic nystagmus. Subjects from pedigree 1 underwent detailed clinical examination including nystagmology. Screening of FRMD7 was undertaken in pedigree 1 and in 37 other congenital idiopathic nystagmus probands and controls. Direct sequencing confirmed sequence changes. X-inactivation studies were performed in pedigree 1. The nystagmus phenotype was extremely variable in pedigree 1. We identified 2 FRMD7 mutations. However, 80% of X-linked families and 96% of simplex cases showed no mutations. X-inactivation studies demonstrated no clear causal link between skewing and variable penetrance. We confirm profound phenotypic variation in X-linked congenital idiopathic nystagmus pedigrees. We demonstrate that other congenital nystagmus genes exist besides FRMD7. We show that the role of X inactivation in variable penetrance is unclear in congenital idiopathic nystagmus. Clinical Relevance We demonstrate that phenotypic variation of nystagmus occurs in families with FRMD7 mutations. While FRMD7 mutations may be found in some cases of X-linked congenital idiopathic nystagmus, the diagnostic yield is low. X-inactivation assays are unhelpful as a test for carrier status for this disease.

Objective: To determine the clinical and biochemical characteristics of children with Juvenile Idiopathic Arthritis (JIA) at a tertiary care centre in Karachi, Pakistan. Study Design: A descriptive study. Place and Duration of Study: Paediatric Rheumatology Clinic of The Aga Khan University Hospital (AKUH), Karachi, from January 2008 to December 2011. Methodology: Clinical and laboratory profile and outcome of children less than 15 years of age attending the Paediatric Rheumatology Clinic of the Aga Khan University, Karachi with the diagnosis of Juvenile Idiopathic Arthritis according to International League against Rheumatism were studied. These children were classified into different types of JIA; their clinical and laboratory characteristics, response to therapy and outcome was evaluated. Results: Sixty eight patients satisfying the criteria of International League against Rheumatism (ILAR) for Juvenile Idiopathic Arthritis were enrolled during the study period of four consecutive years, their age ranged from 9 months to 15 years. Mean age at onset was 6.45 +- 4.03 years while mean age at diagnosis was 7.60 +- 3.93 years. Polyarticular was the most predominant subtype with 37 (54%) patients, out of these, 9 (24%) were rheumatoid factor positive. An almost equal gender predisposition was observed. Fever and arthritis were the most common presenting symptoms, with only 2 patients presenting with uveitis. Conclusion: The clinico-biochemical characteristics of JIA at the study centre showed a pattern distinct with early onset of disease, high frequency of polyarticular type and a higher rheumatoid factor (QRA) and ANA positivity in girls.

2017-01-01

Full Text Available Background. Hypertrophic osteoarthropathy (HOA is a syndrome characterized by abnormal proliferation of the skin and bony structures at the distal extremities resulting in digital clubbing, periosteal bony reaction, and joint effusion. It can be primary (idiopathic without any clear identifiable etiology as well as secondary to variety of systemic diseases most notably lung pathology. Case Presentation. We describe a rare case of primary idiopathic osteoarthropathy in a male patient who presented with severe pain and tenderness in his legs. His history was significant for long standing alcoholism. Physical examination showed severe fingers and toes clubbing. He reported similar changes in his mother. Clinical and radiological findings were remarkable for distal leg tenderness and diffuse periosteal bony reactions, respectively. Computerized tomography scan failed to show any pathology apart from fatty liver infiltration. In the absence of obesity or diabetes, this was consistent with alcoholic steatosis. He was started on nonsteroidal anti-inflammatory drug which dramatically improved his symptoms. Conclusion. Primary hypertrophic osteoarthropathy should be considered in a previously healthy person presenting with bony pain and finger clubbing especially after ruling out the common secondary causes. Moreover, alteration of prostaglandin metabolism secondary to alcoholic consumption might be a contributing factor.

Progressive outer retinal necrosis (PORN) associated with varicella zoster virus (VZV) is usually diagnosed in HIV positive or immunosuppressed patients. We report two cases of immunocompetent patients with necrotizing viral retinitis found to have idiopathic CD4 lymphocytopenia. Clinical presentation, examination, imaging, and laboratory testing of two patients with VZV retinitis are presented. An HIV negative patient with history of herpes zoster presented with rapid loss of vision and examination consistent with PORN. PCR testing confirmed VZV. Lymphocytopenia was noted with a CD4 count of 25/mm(3). A second HIV negative patient presented with blurred vision and lid swelling and was found to have peripheral VZV retinitis confirmed by PCR. Laboratory workup revealed lymphocytopenia with a CD4 count of 133/mm(3). VZV necrotizing retinitis classic for PORN can occur in HIV negative patients. Idiopathic CD4 lymphocytopenia should be considered healthy patients who develop ocular infections seen in the immunocompromised.

Full Text Available Diffuse idiopathic skeletal hyperostosis (DISH is a noninflammatory degenerative disease that affects multiple spine levels and, in combination with osteoporosis, makes vertebrae more prone to fractures, especially in elderly people. We describe a rare case of thoracic fracture in an ankylosed spine in which hemoptysis was the only clinical sign. The patient (age in the early 80s presented with chest pain and a cough associated with hemoptysis. The patient had no complaints of back pain and no neurological symptoms. Computed tomography (CT angiography of the chest revealed changes consistent with DISH, with fractures at the T8 and T9 vertebra as well as lung hemorrhage or contusion in the right lung base. CT and magnetic resonance imaging of the thoracic spine showed similar findings, with a recent T8-T9 fracture and DISH changes. The patient underwent percutaneous pedicle screw fixation from T7 to T11 and remained neurologically intact with an uneventful postoperative course.

Idiopathic pulmonary fibrosis

2008-03-01

Full Text Available Abstract Idiopathic pulmonary fibrosis (IPF is a non-neoplastic pulmonary disease that is characterized by the formation of scar tissue within the lungs in the absence of any known provocation. IPF is a rare disease which affects approximately 5 million persons worldwide. The prevalence is estimated to be slightly greater in men (20.2/100,000 than in women (13.2/100,000. The mean age at presentation is 66 years. IPF initially manifests with symptoms of exercise-induced breathless and dry coughing. Auscultation of the lungs reveals early inspiratory crackles, predominantly located in the lower posterior lung zones upon physical exam. Clubbing is found in approximately 50% of IPF patients. Cor pulmonale develops in association with end-stage disease. In that case, classic signs of right heart failure may be present. Etiology remains incompletely understood. Some environmental factors may be associated with IPF (cigarette smoking, exposure to silica and livestock. IPF is recognized on high-resolution computed tomography by peripheral, subpleural lower lobe reticular opacities in association with subpleural honeycomb changes. IPF is associated with a pathological lesion known as usual interstitial pneumonia (UIP. The UIP pattern consists of normal lung alternating with patches of dense fibrosis, taking the form of collagen sheets. The diagnosis of IPF requires correlation of the clinical setting with radiographic images and a lung biopsy. In the absence of lung biopsy, the diagnosis of IPF can be made by defined clinical criteria that were published in guidelines endorsed by several professional societies. Differential diagnosis includes other idiopathic interstitial pneumonia, connective tissue diseases (systemic sclerosis, polymyositis, rheumatoid arthritis, forme fruste of autoimmune disorders, chronic hypersensitivity pneumonitis and other environmental (sometimes occupational exposures. IPF is typically progressive and leads to significant

To observe the changes in plasma atrial natriuretic factor (AFN) in patients with idiopathic atrial fibrillation and investigate its mechanism, plasma ANF, platelet count and hematocrit were detected in 21 cases with transient idiopathic atrial fibrillation (group A, A1 representing attack, while A2 termination), 28 with persistent idiopathic atrial fibrillation (group B), 27 suffered from rheumatic heart disease with mitral stenosis and persistent atrial fibrillation (group C), 32 with transient supraventricular tachycardia (group D) and 20 normal controls (group E). It was found that the level of ANF was significantly higher in patients with attacking transient idiopathic atrial fibrillation than that in group A2, D and E (P 0.05), while there was significant difference in hematocrit in group A1 compared with group A2, D, E (P < 0.01). It suggested that ANF and hematocrit play an important role in the attack of idiopathic atrial fibrillation

2015-01-01

Full Text Available Bloody tear is a rare and distinct clinic phenomenon. We report a case presenting with the complaint of recurrent episodes of bilateral bloody tearing. A 16-year-old girl presented to our clinic with complaint of bloody tearing in both eyes for 3 months. Bloody tearing was not associated with her menses. A blood-stained discharge from the punctum was not observed during the compression of both nasolacrimal ducts. Nasolacrimal passage was not obstructed. Imaging studies such as dacryocystography and gradient-echo magnetic resonance imaging (MRI of nasolacrimal canal were normal. Intranasal endoscopic evaluation was normal. We collected samples from bloody tears two times and pathological examination was performed. Pathological analysis showed lots of squamous cells and no endometrial cells; dysplastic cells were found. Further evaluations for underlying causes were unremarkable. No abnormalities were found in ophthalmologic, radiologic, and pathologic investigations. This condition is likely a rare abnormality and the least recognized aetiology for the idiopathic phenomenon.

Association between adolescent idiopathic scoliosis prevalence and age at menarche in different geographic latitudes

2006-05-01

Full Text Available Abstract Background Age at menarche is considered a reliable prognostic factor for idiopathic scoliosis and varies in different geographic latitudes. Adolescent idiopathic scoliosis prevalence has also been reported to be different in various latitudes and demonstrates higher values in northern countries. A study on epidemiological reports from the literature was conducted to investigate a possible association between prevalence of adolescent idiopathic scoliosis and age at menarche among normal girls in various geographic latitudes. An attempt is also made to implicate a possible role of melatonin in the above association. Material-methods 20 peer-reviewed published papers reporting adolescent idiopathic scoliosis prevalence and 33 peer-reviewed papers reporting age at menarche in normal girls from most geographic areas of the northern hemisphere were retrieved from the literature. The geographic latitude of each centre where a particular study was originated was documented. The statistical analysis included regression of the adolescent idiopathic scoliosis prevalence and age at menarche by latitude. Results The regression of prevalence of adolescent idiopathic scoliosis and age at menarche by latitude is statistically significant (p Conclusion Late age at menarche is parallel with higher prevalence of adolescent idiopathic scoliosis. Pubarche appears later in girls that live in northern latitudes and thus prolongs the period of spine vulnerability while other pre-existing or aetiological factors are contributing to the development of adolescent idiopathic scoliosis. A possible role of geography in the pathogenesis of idiopathic scoliosis is discussed, as it appears that latitude which differentiates the sunlight influences melatonin secretion and modifies age at menarche, which is associated to the prevalence of idiopathic scoliosis.

We retrospectively investigated 58 patients with PMF treated in our institution in the period from 2006 to 2017. ABC was obtained in addition to other hematological and clinical parameters. Patients were separated into high and low ABC groups using the Receiver operating characteristic curve analysis. ABC was higher in PMF patients than in healthy controls (P constitutional symptoms (P = 0.030) and massive splenomegaly (P = 0.014). ABC was also positively correlated with absolute monocyte count (AMC) (P processes. Hence, both have a potential for improvement of current prognostic scores. Basophils represent a part of malignant clone in PMF and are associated with unfavorable disease features and poor prognosis which is independent of currently established prognostic scoring system and monocytosis.

Full Text Available Idiopathic intracranial hypertension (IIH is a central nervous system disorder characterized by raised intracranial pressure with normal cerebrospinal fluid composition and absence of any structural anomaly on neuroimaging. Among all endocrine disorders associated with the development of IIH, the association of hyperthyroidism and IIH is very rare with few cases reported till date. Thyroid disturbances have a unique association with IIH. Hypo- and hyper-thyroidism have been reported in association with this disorder. We present a rare case of a 25-year-old man with Graves' disease with intractable headache that was later investigated and attributed to development of IIH.

Full Text Available OBJECTIVE: To compare the voice quality of women with idiopathic Parkinson's disease and those without it. METHODS: An evaluation was performed including 19 female patients diagnosed with idiopathic Parkinson's disease, with an average age of 66 years, and 27 women with an average of 67 years-old in the Control Group. The assessment was performed by computed acoustic analysis and perceptual evaluation. RESULTS: Parkinson's disease patients presented moderate rough and unstable voice quality. The parameters of grade, roughness, and instability had higher scores in Parkinson's disease patients with statistically significant differences. Acoustic measures of Jitter and period perturbation quotient (PPQ significantly differ between groups. CONCLUSIONS: Parkinson's disease female individuals showed more vocal alterations compared to the Control Group, when both perceptual and acoustic evaluations were analyzed.

Gene expression profiling with principal component analysis depicts the biological continuum from essential thrombocythemia over polycythemia vera to myelofibrosis

2012-01-01

The recent discovery of the Janus activating kinase 2 V617F mutation in most patients with polycythemia vera (PV) and half of those with essential thrombocythemia (ET) and primary myelofibrosis (PMF) has favored the hypothesis of a biological continuum from ET over PV to PMF. We performed gene...... with biological relevant overlaps between the different entities. Moreover, the analysis separates Janus activating kinase 2-negative ET patients from Janus activating kinase 2-positive ET patients. Functional annotation analysis demonstrates that clusters of gene ontology terms related to inflammation, immune...... system, apoptosis, RNA metabolism, and secretory system were the most significantly deregulated terms in the three different disease groups. Our results yield further support for the hypothesis of a biological continuum originating from ET over PV to PMF. Functional analysis suggests an important...

Idiopathic spontaneous pneumoperitoneum is a rare condition that is characterized by intraperitoneal gas for which no clear etiology has been identified. We report here a case of idiopathic spontaneous pneumoperitoneum, which was successfully managed by conservative treatment. A 77-year-old woman who was bedridden with speech disability as a sequela of brain hemorrhage presented at our hospital with a 1-day history of abdominal distention. On physical examination, she had stable vital signs and slight epigastric tenderness on deep palpation without any other signs of peritonitis. A chest radiograph and computed tomography showed that a large amount of free gas extended into the upper abdominal cavity. Esophagogastroduodenoscopy revealed no perforation of the upper gastrointestinal tract. The patient was diagnosed with idiopathic spontaneous pneumoperitoneum, and conservative treatment was selected. The abdominal distension rapidly disappeared, and the patient resumed oral intake on the 5th hospital day without deterioration of symptoms. Knowledge of this rare disease and accurate diagnosis with findings of clinical imaging might contribute towards refraining from unnecessary laparotomy.

Two patients presented with ureteric obstruction, and voiding symptoms and constipation, respectively, and were examined by means of intravenous urography and computed tomography. One patient was additionally examined by means of MR tomography. After CT (performed in both patients) and MRT (performed in one patient) had shown a diffuse, contrast-enhancing, infiltrating process in the small pelvis with infiltration of adjacent organs and vessels, surgical biopsy proved the diagnosis of idopathic pelvic fibrosis. Extension of retroperitoneal fibrosis below the pelvic rim is very rare. Clinical symptoms of pelvic fibrosis are variable and imaging findings may lead to a broad list of differential diagnoses. We present two patients with idiopathic pelvic fibrosis and discuss radiological findings and differential diagnoses of this rare disease. (orig.)

Gigante, A F; Berardelli, A; Defazio, G

2016-05-01

Tremor in dystonia has been described as a postural or kinetic abnormality. In recent series, however, patients with idiopathic adult-onset dystonia also displayed rest tremor. The frequency and distribution of rest tremor were studied in a cohort of 173 consecutive Italian patients affected by various forms of idiopathic adult-onset dystonia attending our movement disorder clinic over 8 months. Examination revealed tremor in 59/173 patients (34%): 12 patients had head tremor, 34 patients had arm tremor, whilst 13 patients presented tremor in both sites. Head tremor was postural in all patients, whereas arm tremor was postural/kinetic in 28 patients, only at rest in one and both postural/kinetic and at rest in 18 patients. Patients with tremor were more likely to have segmental/multifocal dystonia. Patients who had rest tremor (either alone or associated with action tremor) had a higher age at dystonia onset and a greater frequency of dystonic arm involvement than patients with action tremor alone or without tremor. Both action and rest tremor are part of the tremor spectrum of adult-onset dystonia and are more frequently encountered in segmental/multifocal dystonia. The higher age at dystonia onset and the greater frequency of arm dystonia in patients with rest tremor may have pathophysiological implications and may account, at least in part, for the previous lack of identification of rest tremor as one possible type of tremor present in dystonia. © 2016 EAN.

Single photon emission computed tomography (SPECT) with N-isoprophyl-p [ 123 I]-iodoamphetamine (IMP), X-ray computed tomography (X-CT), and magnetic resonance imaging (MRI) were performed in 20 children with idiopathic seizures. In children with idiopathic seizures, SPECT could detect the abnormal sites at the highest rate (45%) compared with CT (10%) and MRI (12%), but the abnormal sites on SPECT correlated poorly with the foci on electroencephalograph (EEG). Idiopathic epilepsy with hypoperfusion on SPECT was refractory to treatment and was frequently associated with mental and/or developmental retardation. Perfusion defects on SPECT scans probably affect the development and maturation of the brain in children. (author)

Allensworth, Jordan J; O'Dell, Karla D; Schindler, Joshua S

2017-01-01

Diffuse idiopathic skeletal hyperostosis (DISH) is an idiopathic spinal disease common in the elderly and characterized by flowing ossification and osteophyte formation along the spinal column. Cervical hyperostosis is capable of producing dysphagia, stridor, and airway obstruction; however, there are no extant reports of true paralysis of bilateral vocal folds in patients fulfilling the criteria for DISH. We report a case of a 61-year-old man presenting with dysphagia and dyspnea. Flexible laryngoscopy revealed bilateral true vocal fold paralysis. Cervical radiograph showed flowing ossification of the anterior longitudinal ligament with preservation of intervertebral disc height. Tracheotomy and cervical osteophytectomy were performed, after which the patient showed improved swallowing and speaking ability and was decannulated without complication. In the case presented, cervical osteophytectomy dramatically reversed bilateral vocal fold paralysis and dysphagia secondary to hyperostosis, thus negating the need for prolonged tracheostomy and feeding tube dependence. © 2016 Wiley Periodicals, Inc.

2001-02-01

There is scant information about the management of idiopathic megarectum in childhood. Children with idiopathic megarectum referred to a single institution between 1994 and 1998 were identified prospectively. Those with Hirschsprung's disease or an anorectal malformation were excluded. The remaining patient group, 22 boys and 7 girls, had a median age of 8.0 years (range 3.5-14.0 y). Median duration of symptoms prior to referral was 2.0 years (range 0.4-11 y). Chronic soiling was the dominant complaint in 28/29 (97%) cases. 23 children had received regular stimulant laxatives for periods ranging from 1 month to 11 years, and 9 children had been treated with regular enemas. The degree of megarectum assessed by both abdominal palpation and plain radiography was: grade 1 (below umbilical level) n=6; grade 2 (at umbilical level) n=15; and grade 3 (above umbilical level) n=8. Hirschsprung's disease was specifically excluded by rectal biopsy in all cases and no patient had evidence of spinal dysraphism. Three boys with massive megarectums and intractable symptoms were treated by a staged Duhamel sigmoid pull-through with excellent functional results. Fifteen patients (52%) were treated by a single manual evacuation under general anaesthesia followed by a daily Bisacodyl 5-10 mg suppository. After a median follow-up of 16 months, 13 continue to respond well with a daily bowel action and no soiling (4 of the 13 have discontinued treatment and remain well). The remaining 11 patients (38%) have continued conventional treatment with oral laxatives but with limited success. Idiopathic megarectum is poorly described in children. It is more common in boys and is often resistant to laxative therapy alone. After appropriate preparation, treatment with stimulant suppositories can be effective. Surgery has a valuable role in selected patients with a massive megarectum.

Idiopathic Bilateral External Jugular Vein Thrombosis.

Science.gov (United States)

Hindi, Zakaria; Fadhel, Ehab

2015-08-20

Vein thrombosis is mainly determined by 3 factors, which constitute a triad called Virchow's triad: hypercoagulability, stasis, and endothelial injury. Venous thrombosis commonly occurs in the lower extremities since most of the blood resides there and flows against gravity. The veins of the lower extremities are dependent on intact valves and fully functional leg muscles. However, in case of valvular incompetency or muscular weakness, thrombosis and blood stasis will occur as a result. In contrast, the veins of the neck, specially the jugulars, have distensible walls which allow flexibility during respiration. In addition, the blood directly flows downward towards the heart. Nevertheless, many case reports mentioned the thrombosis of internal jugular veins and external jugular veins with identified risk factors. Jugular vein thrombosis has previously been associated in the literature with a variety of medical conditions, including malignancy. This report is of a case of idiopathic bilateral external jugular vein thrombosis in a 21 year-old male construction worker of Southeast Asian origin with no previous medical history who presented with bilateral facial puffiness of gradual onset over 1 month. Doppler ultrasound and computed tomography were used in the diagnosis. Further work-up showed no evidence of infection or neoplasia. The patient was eventually discharged on warfarin. The patient was assessed after 6 months and his symptoms had resolved completely. Bilateral idiopathic external jugular veins thrombosis is extremely rare and can be an indicator of early malignancy or hidden infection. While previous reports in the literature have associated jugular vein thrombosis with malignancy, the present case shows that external jugular vein thrombosis can also be found in persons without malignancy.

Idiopathic sclerosing encapsulating peritonitis (or abdominal cocoon) is a rare cause of small bowel obstruction, especially in adult population. Diagnosis is usually incidental at laparotomy. We discuss one such rare case, outlining the fact that an intra-operative surprise diagnosis could have been facilitated by previous investigations. A 56 year-old man presented in A&E department with small bowel ileus. He had a history of 6 similar episodes of small bowel obstruction in the past 4 years, which resolved with conservative treatment. Pre-operative work-up did not reveal any specific etiology. At laparotomy, a fibrous capsule was revealed, in which small bowel loops were encased, with the presence of interloop adhesions. A diagnosis of abdominal cocoon was established and extensive adhesiolysis was performed. The patient had an uneventful recovery and follow-up. Idiopathic sclerosing encapsulating peritonitis, although rare, may be the cause of a common surgical emergency such as small bowel ileus, especially in cases with attacks of non-strangulating obstruction in the same individual. A high index of clinical suspicion may be generated by the recurrent character of small bowel ileus combined with relevant imaging findings and lack of other plausible etiologies. Clinicians must rigorously pursue a preoperative diagnosis, as it may prevent a "surprise" upon laparotomy and result in proper management.

The relationship between periodontal disease and systemic disease is revealing new and exciting associations. Idiopathic edema presents a clinical syndrome with obscure pathophysiology. The present study investigates whether non-surgical periodontal therapy is beneficial in patients who are not responding to conventional treatment of idiopathic edema. Thirty patients with idiopathic edema were allocated to intervention and control groups. All the subjects were assessed for systemic (body weight, body mass index, visual scale of edema, serum C-reactive protein, and serum albumin) and periodontal (plaque index, calculus index, and gingival index) parameters. Non-surgical periodontal therapy, including oral hygiene instructions, scaling and root planing, and systemic antibiotic therapy, was provided in the intervention group. Both groups were reevaluated after 4 weeks. Both groups were comparable at baseline. All parameters, except serum albumin, showed significant improvement after periodontal therapy. The control group showed further worsening of these parameters. This study shows that sources for systemic inflammation, such as periodontal disease, could affect the pathogenesis of idiopathic edema. Successful elimination of such covert sources of inflammation leads to a clinical benefit in patients who are distressed by this condition.

Oral anticoagulant therapy for more than 6 months in patients with an episode of idiopathic thromboembolic disease is controversial. The objective was to determine predictive clinical signs that identify patients at increased risk of thromboembolic recurrence after stopping anticoagulant therapy for 6 months after an episode of idiopathic deep vein thrombosis (DVT). A prospective study which included 306 consecutive patients with a first episode of idiopathic DVT from June 2012 to June 2014. Predictor variables of recurrent thromboembolic disease and episodes of recurrence during follow-up of the patients (28.42 months) were collected. We performed a multivariate analysis to analyze possible predictors (Pthrombus (P=.001) in males, and persistence of residual thrombus in women (P=.046). The mean recurrence-free survival was shorter in both groups. The presence of echogenic thrombus in men and the existence of residual DVT in women were 2 clinical signs associated with increased risk of thromboembolic recurrence after stopping anticoagulant therapy for 6 months after an episode of idiopathic DVT in our study.

2015-11-01

To evaluate the role of nasal bacterial colonization in cases of idiopathic epistaxis in children. A descriptive, hospital based, observational study in our hospital was conducted on total 112 pediatric patients in the age group 4-16 years. Group A (control): 56 patients with no epistaxis; Group B (epistaxis): 56 patients with idiopathic epistaxis. A swab for microbiological evaluation was taken from the anterior nasal cavity of each child. A highly significant association between nasal colonization with pathological Staphylococcus aureus and idiopathic epistaxis was found. The presence of pathological S. aureus colonization in the anterior nasal cavity was also associated with statistically significant number of crusting and presence of dilated blood vessels on the anterior nasal septum of children in epistaxis group. Nasal bacterial colonization with S. aureus leads to a sequence of pathological events i.e. low grade inflammation, crusting and new vessel formation. This leads to irritation in nasal cavity resulting in digital trauma and subsequently epistaxis and thus it plays an important role in causing idiopathic epistaxis in children.

Familial or Sporadic Idiopathic Scoliosis – classification based on artificial neural network and GAPDH and ACTB transcription profile

Science.gov (United States)

2013-01-01

Background Importance of hereditary factors in the etiology of Idiopathic Scoliosis is widely accepted. In clinical practice some of the IS patients present with positive familial history of the deformity and some do not. Traditionally about 90% of patients have been considered as sporadic cases without familial recurrence. However the exact proportion of Familial and Sporadic Idiopathic Scoliosis is still unknown. Housekeeping genes encode proteins that are usually essential for the maintenance of basic cellular functions. ACTB and GAPDH are two housekeeping genes encoding respectively a cytoskeletal protein β-actin, and glyceraldehyde-3-phosphate dehydrogenase, an enzyme of glycolysis. Although their expression levels can fluctuate between different tissues and persons, human housekeeping genes seem to exhibit a preserved tissue-wide expression ranking order. It was hypothesized that expression ranking order of two representative housekeeping genes ACTB and GAPDH might be disturbed in the tissues of patients with Familial Idiopathic Scoliosis (with positive family history of idiopathic scoliosis) opposed to the patients with no family members affected (Sporadic Idiopathic Scoliosis). An artificial neural network (ANN) was developed that could serve to differentiate between familial and sporadic cases of idiopathic scoliosis based on the expression levels of ACTB and GAPDH in different tissues of scoliotic patients. The aim of the study was to investigate whether the expression levels of ACTB and GAPDH in different tissues of idiopathic scoliosis patients could be used as a source of data for specially developed artificial neural network in order to predict the positive family history of index patient. Results The comparison of developed models showed, that the most satisfactory classification accuracy was achieved for ANN model with 18 nodes in the first hidden layer and 16 nodes in the second hidden layer. The classification accuracy for positive Idiopathic

Idiopathic pulmonary fibrosis: from clinical trials to real-life experiences

Directory of Open Access Journals (Sweden)

Sergio Harari

2015-09-01

Full Text Available Randomised controlled clinical trials are fundamental in medicine to develop new effective drugs and new therapeutic regimens and are the strength of evidence-based medicine. These studies allow us to avoid the repetition of misleading experiences that have been reported in the past, where drugs or associations were utilised without compelling evidence and ultimately proven to be ineffective. In recent years, randomised clinical trials have been conducted and concluded for many rare diseases, including idiopathic pulmonary fibrosis. However, clinical trials do not always reflect the real-life scenario. Patients selected for clinical trials present fewer comorbidities, they fall between certain age limits, and the severity of their disease is defined; therefore, they do not always reflect the whole of the population affected by a specific disease. These are the reasons why we also need data that mirror real-life experience. The limitations that these kind of studies present are always several and the studies should be interpreted with caution, although they can fill the important gap between efficacy and effectiveness. In this article, we will review the existing clinical data on real-life treatment of idiopathic pulmonary fibrosis.

Serial derotational casting has been used as a definitive treatment or as delaying strategy in progressive idiopathic (IS) and non-idiopathic (NIS) early-onset scoliosis (EOS). Retrospective chart and radiographic review of patients who underwent serial casting for progressive EOS between 2005 and 2012 at a single institution. A total of 74 consecutive patients entered serial cast treatment. Twenty-eight were currently being casted, 30 completed cast treatment and were converted to thoracolumbosacral orthosis (TLSO), 9 were treated surgically, 6 were lost to follow-up, and 1 had no further treatment. The researchers diagnosed IS in 41 patients; 33 had NIS. At presentation the IS group had an average Cobb angle (CA) of 49° and a rib vertebral angle difference (RVAD) of 37°. The NIS group had a CA of 51° (p = .69) and RVAD of 37° (p = .94). In patients currently being casted, 19 IS patients had a decreased CA, from 47° to 27°. The 9 NIS patients had a decreased CA, from 62° to 57° (p = .0002). Cobb angle improvement was significantly better in IS (p = .0005). In the TLSO group the 17 IS patients had a decreased average CA, from 46° to 18°, after serial casting and the 13 NIS patients decreased CA from 42° to 32°. Patients with IS had better improvement in CA than the NIS group (p Casting initiated before age 2 years yielded better curve correction for IS (p casting than NIS patients. Casting in IS patients before age 24 months yielded better curve correction. Patients who required surgery had a higher age and Cobb angle at presentation than those who transitioned to a TLSO. The surgical group was observed for a similar duration of time and there was no significant statistical difference. Although RVAD is a predictor of progression in infantile IS, it did not show a predictive value in the response to casting of either the IS or NIS groups. Copyright © 2015 Scoliosis Research Society.

Full Text Available Brett Ley, Harold R Collard Department of Medicine, Division of Pulmonary and Critical Care Medicine, University of California San Francisco, San Francisco, California, USA Abstract: Idiopathic pulmonary fibrosis is a chronic fibrotic lung disease of unknown cause that occurs in adults and has a poor prognosis. Its epidemiology has been difficult to study because of its rarity and evolution in diagnostic and coding practices. Though uncommon, it is likely underappreciated both in terms of its occurrence (ie, incidence, prevalence and public health impact (ie, health care costs and resource utilization. Incidence and mortality appear to be on the rise, and prevalence is expected to increase with the aging population. Potential risk factors include occupational and environmental exposures, tobacco smoking, gastroesophageal reflux, and genetic factors. An accurate understanding of its epidemiology is important, especially as novel therapies are emerging.

The study of respiratory fuctions is of key importance for the clinical evaluation of patients with idiopathic scoliosis. Such study has been traditionally based on classical pulmonary function tests and arterial hemogasanalysis. However, neither procedure gives any information on the topographical distribution of abnormalities, and both might be suboptimal as far as sensitivity is concerned. The preliminary results obtained with radioaerosol lung scintigraphy in 11 patients with scoliosis are here presented. They lead to the conclusion that radioaerosol lung scintigraphy, besides being an useful adjunct to more traditional diagnostic procedures, can yield unique information on the localization of convective ventilation derangements induced by the dynamic abnormalities of the rib cage

Idiopathic calcinosis cutis refers to progressive deposition of crystals of calcium phosphate in the skin and other areas of the body, in the absence of any inciting factor. Idiopathic calcinosis cutis may sometimes take the form of small, milia-like lesions. Most commonly, such milia like lesions are seen in the setting of Down syndrome. Herein, we report a 5-year-old girl with multiple asymptomatic discrete milia-like firm papules distributed over the face and extremities. A diagnosis of milia-like idiopathic calcinosis cutis associated with Down Syndrome was provisionally made and was confirmed by histopathology and karyotyping.

Systemic juvenile idiopathic arthritis is a rare febrile arthritis of childhood characterized by a potentially severe course, including prolonged glucocorticoid exposure, growth failure, destructive arthritis, and life-threatening macrophage activation syndrome. Early cytokine-blocking biologic therapy may improve long-term outcomes, although some systemic juvenile idiopathic arthritis patients respond well to non-biologic treatment, leaving optimal management undefined. Consequently, treatment of new-onset systemic juvenile idiopathic arthritis by expert clinicians varies widely. To describe a pragmatic, observational comparative effectiveness study that takes advantage of diversity in the management of a rare disease: FiRst-Line Options for Systemic juvenile idiopathic arthritis Treatment (FROST), comparing non-biologic and biologic consensus treatment plans for new-onset systemic juvenile idiopathic arthritis within the 60-center Childhood Arthritis and Rheumatology Research Alliance Registry (CARRA). FiRst-Line Options for Systemic juvenile idiopathic arthritis Treatment (FROST) is a multicenter, prospective, non-randomized study that compares four Childhood Arthritis and Rheumatology Research Alliance (CARRA) consensus treatment plans for new-onset systemic juvenile idiopathic arthritis: (1) glucocorticoids alone, (2) methotrexate, (3) interleukin-1 blockade, and (4) interleukin-6 blockade. Patients consenting to participation in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry are started on one of four Consensus Treatment Plans at the discretion of the treating physician. The outcome of primary interest is clinically inactive disease off glucocorticoids at 9 months, comparing non-biologic (Consensus Treatment Plans 1 + 2) versus biologic (Consensus Treatment Plans 3 + 4) strategies. Bayesian analytic methods will be employed to evaluate response rates, using propensity scoring to balance treatment groups for potential

Full Text Available Background Oxidative stress is the result of an imbalance between the production and scavenging of reactive oxygen species (ROS. Recently, oxidative stress has been introduced as a major cause of male infertility. Objectives The aim of the present study was to determine the correlation between total antioxidant capacity (TAC and malondialdehyde (MDA as markers of oxidative stress in relation to idiopathic male infertility and sperm parameters. Patients and Methods This case control study was conducted using 35 men with idiopathic infertility and 34 men with proven fertility. Seminal plasma TAC and MDA were measured by ferric reducing ability of plasma (FRAP and thiobarbituric acid (TBA reaction methods, respectively. Results Seminal TAC levels were significantly lower and seminal MDA levels were significantly higher in men with idiopathic infertility than in fertile men (P < 0.0001 and P = 0.004, respectively. A positive correlation was shown between sperm motility, sperm morphology, and TAC levels in men with idiopathic infertility (P = 0.002 and P = 0.002, respectively. In addition, there was a correlation between sperm motility and TAC levels in fertile men (P = 0.005. There was no correlation between sperm count and TAC levels in either men with idiopathic infertility or in fertile men. Negative correlations were observed between MDA levels and sperm motility, morphology, and sperm count only in men with idiopathic infertility (P = 0.003, P = 0.001, and P = 0.006, respectively. Conclusions Our results show that oxidative stress could play an important role in male infertility as well as in sperm motility and sperm morphology.

Idiopathic pulmonary fibrosis (IPF) is a progressive, irreversible, and typically fatal lung disease characterised by subpleural fibrosis, subepithelial fibroblast foci, and microscopic honeycombing. Although understanding of the pathogenic mechanisms continues to evolve, evidence indicates that distal airway and alveolar epithelial cells are central drivers of the disease. In this Viewpoint, we review the history of naming and classifications used to define the disease now referred to as IPF, in the context of understanding the clinical presentation, causes, and pathogenesis of the disease. We aim to generate discussion on whether, given the substantial progress made in understanding the clinical, genetic, cellular, and molecular mechanisms involved in the development of IPF, a change of name should be considered. To initiate this discussion, we offer new suggestions to update the name of this disease and new approaches to classify all forms of pulmonary fibrosis. PMID:29413083

Myelofibrosis (MF) is a clonal hematopoietic malignancy characterized by constitutional and localized symptoms, progressive splenomegaly, bone marrow fibrosis, and cytopenias. Although MF is well studied, few studies exist regarding its symptomatic burden in routine clinical practice. This study aimed to characterize symptoms and other clinical features of MF among patients in the United States. We conducted a retrospective medical record review of adult patients with an MF diagnosis between 1 January 2005 and 31 March 2010, stratified by the presence of palpable splenomegaly. Eligible patients had 12 months or more of follow-up after diagnosis (or after detection of splenomegaly, if present) unless death occurred. Demographic and clinical characteristics, MF-related symptoms, and treatments were reported by treating physicians. We report on 180 MF patients: 102 with splenomegaly, 78 without. Median age was 66 years, 63% were male, and 82% had intermediate-2 or high-risk MF (International Prognostic Scoring System). Fatigue was reported by ∼85% of patients; weight loss, night sweats, and fever (any grade) were each reported by 50% or more of patients. Generalized abdominal pain, left subcostal pain, and early satiety occurred more frequently among patients with splenomegaly. Multiple symptoms were reported by 95% of patients. Common comorbidities were hypertension, diabetes, and chronic pulmonary disease. Symptoms are common in MF patients, regardless of the presence of palpable splenomegaly. Careful assessment of symptom burden is an important aspect of the clinical evaluation of patients with MF

Zamani Farhad

2009-02-01

Full Text Available Abstract Introduction Idiopathic portal hypertension is a disorder of unknown etiology, clinically characterized by portal hypertension, splenomegaly and anemia secondary to hypersplenism. Case presentation A 54-year-old man was admitted to our hospital for evaluation of malaise, weight loss, abdominal swelling and lower limb edema. His paraclinical tests revealed pancytopenia, large ascites, splenomegaly and esophageal varices consistent with portal hypertension. Duodenal biopsy and serologic findings were compatible with celiac disease. His symptoms improved on a gluten-free diet, but his clinical course was further complicated with ulcerative jejunoileitis, and intestinal T-cell lymphoma. Conclusion It seems that celiac disease, by an increased immune reaction in the splenoportal axis, can result in the development of idiopathic portal hypertension in susceptible affected patients.

Of the disorders accompanied by hypertrophy of the extraocular muscles, differentiating between idiopathic orbital inflammation and malignant lymphoma is difficult but important to treatment and prognosis. In this study using MRI, shape, signal intensity, and enhancement effects were compared between idiopathic orbital inflammation and lymphoproliferative lesions. The subjects were 27 patients (8 with idiopathic orbital inflammation, 1 with reactive lymphoid hyperplasia, 3 with atypical lymphoid hyperplasia, and 15 with malignant lymphoma) and 10 normal controls. The evaluation items were: thickness of extraocular muscles, number of extraocular muscles involved signal intensity of extraocular muscles, and enhancement effects on extraocular muscles. When compared to control subjects (p<0.05) the attachment portion of extraocular muscles were significantly thicker in the patients with idiopathic orbital inflammation, atypical lymphoid hyperplasia, or malignant lymphoma; the most marked hypertrophy was observed in patients with malignant lymphoma. The number of extraocular muscles involved was 1.5 (mean) in the patients with idiopathic orbital inflammation, 1 in the patient with reactive lymphoid hyperplasia, 1.7 (mean) in the patients with atypical lymphoid hyperplasia, and 5.1 (mean) in those with malignant lymphoma. The signal intensity ratio on T1W-images did not significantly differ between the patients and controls for all the disorders investigated. Signal intensity ratio on T2W-images significantly differed between patients with atypical lymphoid hyperplasia or malignant lymphoma and the controls (p<0.05) but not between patients with idiopathic orbital inflammation and controls. Signal intensity ratio after contrast enhancement differed significantly only between patients with idiopathic orbital inflammation and controls (p<0.05). (author)

Full Text Available Idiopathic condylar resorption (ICR, also known as idiopathic condylysis or condylar atrophy, is multifactorial pathology leading to severe mandibular retrognathism. The etiology has been shown to be multifactorial, such as avascular necrosis, traumatic injuries, hormone and autoimmune disease and it is largely difficult to distinguish the exact cause in each individual. In spite of the remarkable morphological alteration, surgical intervention is not readily recruited due to the possibility of recurrence of resorption. In order to restore balanced facial profile and occlusion. In this report, we present a camouflage treatment for skeletal Class II with ICR and facial asymmetry involving total arch movement, for the improvement facial profile and reconstruction of occlusion.

Debate: idiopathic short stature should be treated with growth hormone.

Science.gov (United States)

Ambler, Geoffrey R; Fairchild, Jan; Wilkinson, Dominic J C

2013-03-01

In this paper we outline the case for and against the treatment of idiopathic short stature with growth hormone. Drs Ambler and Fairchild argue that many of those with 'idiopathic' short stature are not 'short, normal children' and will ultimately receive molecular diagnoses. They also argue that there is a subset of children who suffer negative psychosocial consequences of their stature for whom growth hormone therapy is effective. Growth hormone has a very good safety record and is likely to be as cost-effective in idiopathic short-stature as in some other conditions that are currently funded. Dr Wilkinson counters that short stature is not associated with physical or psychological illness, and that there is no evidence that growth hormone improves psychological or physical wellbeing. Moreover, growth hormone for idiopathic short stature represents a form of enhancement rather than treatment, and is not a fair use of resources. Socially mediated disadvantage should be treated by attention to prejudice and not by hormone treatment. © 2012 The Authors.

Mallau, Sophie; Bollini, Gérard; Jouve, Jean-Luc; Assaiante, Christine

2007-01-01

Locomotor balance control assessment was performed to study the effect of idiopathic scoliosis on head-trunk coordination in 17 patients with adolescent idiopathic scoliosis (AIS) and 16 control subjects. The aim of this study was to explore the functional effects of structural spinal deformations like idiopathic scoliosis on the balance strategies used during locomotion. Up to now, the repercussion of the idiopathic scoliosis on head-trunk coordination and balance strategies during locomotion is relatively unknown. Seventeen patients with AIS (mean age 14 years 3 months, 10 degrees 30 degrees) and 16 control subjects (mean age 14 years 1 month) were tested during various locomotor tasks: walking on the ground, walking on a line, and walking on a beam. Balance control was examined in terms of rotation about the vertical axis (yaw) and on a frontal plane (roll). Kinematics of foot, pelvis, trunk, shoulder, and head rotations were measured with an automatic optical TV image processor in order to calculate angular dispersions and segmental stabilizations. Decreasing the walking speed is the main adaptive strategy used in response to balance problems in control subjects as well as patients with AIS. However, patients with AIS performed walking tasks more slowly than normal subjects (around 15%). Moreover, the pelvic stabilization is preserved, despite the structural changes affecting the spine. Lastly, the biomechanical defect resulting from idiopathic scoliosis mainly affects the yaw head stabilization during locomotion. Patients with AIS show substantial similarities with control subjects in adaptive strategies relative to locomotor velocity as well as balance control based on segmental stabilization. In contrast, the loss of the yaw head stabilization strategies, mainly based on the use of vestibular information, probably reflects the presence of vestibular deficits in the patients with AIS.

Idiopathic esophageal achalasia is an inflammatory disease of unknown origin, characterized by aperistalsis of the esophageal body and failure of the lower esophageal sphincter in response to swallowing, with consequent dysphagia. To demonstrate the results of surgical therapy in these patients, evaluating the occurred local and systemic complications. Were studied retrospectively 32 patients, 22 of whom presented non-advanced stage of the disease (Stage I/II) and 10 with advanced disease (Stage III/IV). All of them had the clinical conditions to be submitted to surgery. The diagnoses were done by clinical, endoscopic, cardiological, radiological and esophageal manometry analysis. Pre-surgical evaluation was done with a questionnaire based on the most predisposing factors in the development of the disease and the surgical indication was based on the stage of the disease. The patients with non-advanced stages were submitted to cardiomyotomy with fundoplication, wherein in the post-surgical early assessment, only one (4,4%) presented pulmonary infection, but had a good outcome. In patients with advanced disease, seven were submitted to esophageal mucosectomy preserving the muscular layer, wherein one patient (14,2%) presented dehiscence of gastric cervical esophagus anastomosis as well as pulmonary infection; all of these complications were resolved with proper specific treatment; the other three patients with advanced stage were submitted to transmediastinal esophagectomy; two of them presented hydropneumothorax with good evolution, and one of them also presented fistula of the cervical esophagogastric anastomosis, but with spontaneous healing after conservative treatment and nutritional support. The two patients with fistula of the cervical anastomosis progressed to stenosis, with good results after endoscopic dilations. In the medium and long term assessment done in 23 patients, all of them reported improvement in life quality, with return to swallowing. The

2013-07-01

Full Text Available The pathogenesis of idiopathic non-cirrhotic portal hypertension (INCPH remains unknown and the disease is diagnosed by the absence of recognized clinical indicators of cirrhosis and of any other known etiologies of portal hypertension. To promote understanding of this disease, a comprehensive overview of potential etiologies, clinical manifestations, histopathological features, methods of diagnosis and potential differential diagnoses, and outcome of clinical management is presented in this review. In particular, we discuss the findings from INCPH studies and their implications in regards to each of the above-mentioned categories. For example, associations with various comorbidities have suggested a possible immune system component to INCPH development and/or progression. In addition, the common clinical characteristics of patients upon presentation can not only help to recognize disease suspects but may also provide insights into the pathogenesis and prognosis. Finally, prognosis following the various intervention strategies appears to depend mainly on severity of the portal hypertension, as well as its various accompanying complications.

Fluid Distribution Pattern in Adult-Onset Congenital, Idiopathic, and Secondary Normal-Pressure Hydrocephalus: Implications for Clinical Care.

Yamada, Shigeki; Ishikawa, Masatsune; Yamamoto, Kazuo

2017-01-01

In spite of growing evidence of idiopathic normal-pressure hydrocephalus (NPH), a viewpoint about clinical care for idiopathic NPH is still controversial. A continuous divergence of viewpoints might be due to confusing classifications of idiopathic and adult-onset congenital NPH. To elucidate the classification of NPH, we propose that adult-onset congenital NPH should be explicitly distinguished from idiopathic and secondary NPH. On the basis of conventional CT scan or MRI, idiopathic NPH was defined as narrow sulci at the high convexity in concurrent with enlargement of the ventricles, basal cistern and Sylvian fissure, whereas adult-onset congenital NPH was defined as huge ventricles without high-convexity tightness. We compared clinical characteristics and cerebrospinal fluid distribution among 85 patients diagnosed with idiopathic NPH, 17 patients with secondary NPH, and 7 patients with adult-onset congenital NPH. All patients underwent 3-T MRI examinations and tap-tests. The volumes of ventricles and subarachnoid spaces were measured using a 3D workstation based on T2-weighted 3D sequences. The mean intracranial volume for the patients with adult-onset congenital NPH was almost 100 mL larger than the volumes for patients with idiopathic and secondary NPH. Compared with the patients with idiopathic or secondary NPH, patients with adult-onset congenital NPH exhibited larger ventricles but normal sized subarachnoid spaces. The mean volume ratio of the high-convexity subarachnoid space was significantly less in idiopathic NPH than in adult-onset congenital NPH, whereas the mean volume ratio of the basal cistern and Sylvian fissure in idiopathic NPH was >2 times larger than that in adult-onset congenital NPH. The symptoms of gait disturbance, cognitive impairment, and urinary incontinence in patients with adult-onset congenital NPH tended to progress more slowly compared to their progress in patients with idiopathic NPH.

Full Text Available Diffuse idiopathic skeletal hyperostosis (DISH is usually asymptomatic. However, rarely, it causes dysphagia, hoarseness, dyspnea, snoring, stridor, and laryngeal edema. Herein, we present a patient with DISH causing dysphagia. A 70-year-old man presented with a 4-month history of sore throat, dysphagia, and foreign body sensation. Flexible laryngoscopy revealed a leftward-protruding posterior wall in the hypopharynx. Computed tomography and magnetic resonance imaging revealed a bony mass pushing, anteriorly, on the posterior hypopharyngeal wall. Ossification included an osseous bridge involving 5 contiguous vertebral bodies. Dysphagia due to DISH was diagnosed. His symptoms were relieved by conservative therapy using anti-inflammatory drugs. However, if conservative therapy fails and symptoms are severe, surgical treatments must be considered.

Idiopathic pulmonary fibrosis: evolving concepts.

Idiopathic pulmonary fibrosis (IPF) occurs predominantly in middle-aged and older adults and accounts for 20% to 30% of interstitial lung diseases. It is usually progressive, resulting in respiratory failure and death. Diagnostic criteria for IPF have evolved over the years, and IPF is currently defined as a disease characterized by the histopathologic pattern of usual interstitial pneumonia occurring in the absence of an identifiable cause of lung injury. Understanding of the pathogenesis of IPF has shifted away from chronic inflammation and toward dysregulated fibroproliferative repair in response to alveolar epithelial injury. Idiopathic pulmonary fibrosis is likely a heterogeneous disorder caused by various interactions between genetic components and environmental exposures. High-resolution computed tomography can be diagnostic in the presence of typical findings such as bilateral reticular opacities associated with traction bronchiectasis/bronchiolectasis in a predominantly basal and subpleural distribution, along with subpleural honeycombing. In other circumstances, a surgical lung biopsy may be needed. The clinical course of IPF can be unpredictable and may be punctuated by acute deteriorations (acute exacerbation). Although progress continues in unraveling the mechanisms of IPF, effective therapy has remained elusive. Thus, clinicians and patients need to reach informed decisions regarding management options including lung transplant. The findings in this review were based on a literature search of PubMed using the search terms idiopathic pulmonary fibrosis and usual interstitial pneumonia, limited to human studies in the English language published from January 1, 2000, through December 31, 2013, and supplemented by key references published before the year 2000.

Yoon, Young Cheol; Suh, Gee Young; Han, Joung Ho; Lee, Kyung Soo

2002-01-01

Idiopathic interstitial pneumonias are at present classified as one of four types: usual, nonspecific, acute, or desquamative. The acute form has the worst prognosis, followed by the usual and the nonspecific form; it is in desquamative cases that prognosis is best. At high-resolution CT, usual interstitial pneumonia, the most frequent type, manifests as patchy subpleural areas of ground-glass attenuation, irregular linear opacity, and honeycombing, which the nonspecific type, the second most frequent, appears as subpleural patchy areas of ground-glass attenuation with associated areas of irregular linear opacity. Acute interstitial pneumonia demonstrates extensive bilateral airspace consolidation and patchy or diffuse bilateral areas of ground-glass attenuation in middle and lower lung zones

Purpose: To evaluate the usefulness of interventional radiological treatment for idiopathic portal hypertension. Methods: Between 1995 and 1998, we performed an interventional radiological treatment in five patients with idiopathic portal hypertension, four of whom had refused surgery and one of whom had undergone surgery. Three patients with gastroesophageal varices (GEV) were treated by partial splenic embolization (PSE), one patient with esophageal varices (EV) and massive ascites by transjugular intrahepatic portosytemic shunt (TIPS) and PSE, and one patient with GEV by percutaneous transhepatic obliteration (PTO). Midterm results were analyzed in terms of the effect on esophageal and/or gastric varices. Results: In one woman with severe GEV who underwent three sessions of PSE, there was endoscopic confirmation that the GEV had disappeared. In one man his EV shrunk markedly after two sessions of PSE. In two patients slight reduction of the EV was obtained with one application of PSE combined with endoscopic variceal ligation therapy. PTO for GV in one patient resulted in good control of the varices. All patients have survived for 16-42 months since the first interventional treatment, and varices are well controlled. Conclusion: Interventional radiological treatment is effective for patients with idiopathic portal hypertension, whether or not they have undergone surgery

Idiopathic toe walking, a differential diagnosis for neurological and orthopaedic disorders, has been associated with neurodevelopmental alterations. Neurodevelopmental assessment at early ages using specific tests may improve management and follow-up of these patients. The aim of our study is to analyse the neurodevelopmental characteristics of preschool idiopathic toe-walkers (ITW) by comparing them to a control group. Our descriptive cross-sectional study compared possible risk factors, neurodevelopmental characteristics, and scores on the Child Neuropsychological Maturity Questionnaire (CUMANIN) between a group of 56 ITWs aged 3 to 6 and a control group including 40 children. The proportion of males was significantly higher in the ITW group (P=.008). The percentage of patients with a family history (P=.000) and biological risk factors during the perinatal period (P=.032) was also higher in this group. According to the parents' reports, motor coordination in ITWs was significantly poorer (59%; P=.009). ITWs scored significantly lower on CUMANIN subscales of psychomotricity (=0,001) and memory (P=.001), as well as in verbal development (P=.000), non-verbal development (P=.026), and overall development (P=.004). Foot preference was less marked in the ITW group (P=.047). The neurodevelopmental characteristics of our sample suggest that idiopathic toe walking is a marker of neurodevelopmental impairment. However, further studies are necessary to confirm these findings. Copyright © 2016 Sociedad Española de Neurología. Publicado por Elsevier España, S.L.U. All rights reserved.

Gastaut type idiopathic childhood occipital epilepsy is an uncommon epileptic syndrome characterised by frequent seizures, most commonly presenting as elementary visual hallucinations or blindness. Other occipital (non-visual) symptoms may also occur. Interictal EEG typically shows occipital paroxysms, often with fixation-off sensitivity. Ictal EEG is usually characterised by interruption by paroxysms and sudden appearance of low-voltage, occipital, fast rhythm and/or spikes. Despite well described clinical and EEG patterns, to our knowledge, there are very few reports in the literature with video-EEG recording of either seizure semiology or fixation-off phenomena. We present a video-EEG recording of a 12-year-old girl with Gastaut type epilepsy, illustrating the interictal and ictal aspects of this syndrome. Our aim was to demonstrate the clinical and neurophysiological pattern of a typical seizure of Gastaut type epilepsy, as well as the fixation-off phenomena, in order to further clarify the typical presentation of this syndrome.

Background: Steroid-resistant nephrotic syndrome (SRNS) is a common problem but difficult to treat for pediatric nephrologists. Due to paucity of studies done in few centres in southern Pakistan regarding the histopathological aspects in paediatric patients with SRNS, this study was conducted to determine the histopathological spectrum in children with SRNS at our centre. Method: This descriptive study has been conducted at the Nephrology department, The Children's Hospital Lahore from February 2014 to January 2015. Based upon history, physical examination and laboratory results, all patients diagnosed as idiopathic SRNS were included in the study and renal biopsy was done to determine the underlying pathology. Histopathology reports were retrieved and data analysis done using SPSS-20.0. Results: There were a total of 96 patients, 64 (66.7 percentage) males and 32 (33.3 percentage) females. The age range was from 0.80 to 15 years with mean age of presentation being 6.34+3.75 years. The most common histo-pathological pattern was mesangio-proliferative Glomerulonephritis found in 79 (82.3 percentage) cases followed by Focal segmental glomerulosclerosis (FSGS) in 9 (9.4 percentage) patients while Minimal change disease (MCD) was seen in 5 (5.2 percentage) subjects. Conclusion: Mesangioproliferative glomerulonephritis is the most common histological pattern seen in children presenting with idiopathic SRNS at our centre followed by FSGS and MCD. (author)

Impact of JAK2V617F Mutational Status on Phenotypic Features in Essential Thrombocythemia and Primary Myelofibrosis

Directory of Open Access Journals (Sweden)

2016-05-01

Full Text Available Objective: The JAK2V617F mutation is present in the majority of patients with essential thrombocythemia (ET and primary myelofibrosis (PMF. The impact of this mutation on disease phenotype in ET and PMF is still a matter of discussion. This study aims to determine whether there are differences in clinical presentation and disease outcome between ET and PMF patients with and without the JAK2V617F mutation. Materials and Methods: In this single-center study, a total of 184 consecutive Philadelphia-negative chronic myeloproliferative neoplasms, 107 cases of ET and 77 cases of PMF, were genotyped for JAK2V617F mutation using the JAK2 Ipsogen MutaScreen assay, which involves allele-specific polymerase chain reaction. Results: ET patients positive for JAK2V617F mutation had higher hemoglobin (Hb and hematocrit (Hct levels, lower platelet counts, and more prevalent splenomegaly at diagnosis compared to patients negative for the JAK2V617F mutation, but rates of major thrombotic events, arterial thrombosis, and venous thrombosis were comparable between the groups. At presentation, PMF patients with JAK2V617F mutation had significantly higher Hb and Hct levels and leukocyte counts than patients without the mutation. Similar to the findings of ET patients, thromboembolic rates were similar in PMF patients with and without theJAK2V617F mutation. For ET and PMF patients, no difference was observed in rates of death with respect to JAK2V617F mutational status. Moreover, leukemic transformation rate was not different in our PMF patients with and without JAK2V617F mutation. Conclusion: We conclude that JAK2V617F-mutated ET patients express a polycythemia vera-like phenotype and JAK2V617F mutation in PMF patients is associated with a more pronounced myeloproliferative phenotype.

Idiopathic noncirrhotic portal hypertension: current perspectives.

Science.gov (United States)

Riggio, Oliviero; Gioia, Stefania; Pentassuglio, Ilaria; Nicoletti, Valeria; Valente, Michele; d'Amati, Giulia

2016-01-01

The term idiopathic noncirrhotic portal hypertension (INCPH) has been recently proposed to replace terms, such as hepatoportal sclerosis, idiopathic portal hypertension, incomplete septal cirrhosis, and nodular regenerative hyperplasia, used to describe patients with a hepatic presinusoidal cause of portal hypertension of unknown etiology, characterized by features of portal hypertension (esophageal varices, nonmalignant ascites, porto-venous collaterals), splenomegaly, patent portal, and hepatic veins and no clinical and histological signs of cirrhosis. Physicians should learn to look for this condition in a number of clinical settings, including cryptogenic cirrhosis, a disease known to be associated with INCPH, drug administration, and even chronic alterations in liver function tests. Once INCPH is clinically suspected, liver histology becomes mandatory for the correct diagnosis. However, pathologists should be familiar with the histological features of INCPH, especially in cases in which histology is not only requested to exclude liver cirrhosis.

Manual Therapy in the Treatment of Idiopathic Scoliosis. Analysis of Current Knowledge.

Apart from the recommended specific physiotherapy, the treatment of idiopathic scoliosis (IS) also incorporates non-specific manual therapy (NMT). The aim of this paper is to assess the efficacy of NMT (manual therapy, chiropractic, osteopathy) used in the treatment of children and adolescents with IS. The study analysed systematic reviews (Analysis 1) and other recent scientific publications (Analysis 2). Analysis 1 encompassed papers on the use of NMT in patients with IS. Works concerning specific physiotherapy (SP) or bracing (B) and other types of scoliosis were excluded from the analysis. Inclusion criteria for Analysis 2 were: treatment with NMT; subjects aged 10-18 years with IS. The following types of papers were excluded: works analysing NMT combined with SP or B, reports concerning adult pa tients, analyses of single cases and publications included in Analysis 1. Analysis 1: six systematic reviews contained 6 papers on the efficacy of NMT in the treatment of IS. The results of these studies are contradictory, ranging from Cobb angle reduction to no treatment effects whatsoever. The papers analysed are characterised by poor methodological quality: small group sizes, incomplete descriptions of the study groups, no follow-up and no control groups. Analysis 2: in total, 217 papers were found. None of them met the criteria set for the analysis. 1. Few papers verifying the efficacy of manual therapy, chiropractic and osteopathy in the treatment of idiopathic scoliosis have been published to date. 2. The majority are experimental studies with poor methodology or observational case studies. 3. At present, the efficacy of non-specific manual therapy in the treatment of patients with idiopathic scoliosis cannot be reliably evaluated. 4. It is necessary to conduct further research based on appropriate methods (prospective, rando mi s ed, controlled studies) in order to reliably assess the usefulness of non-specific manual therapy in the treatment of idiopathic

This paper is a case presentation of a idiopathic cerebral calcification manifesting itself as a Parkinsonism. The patient, a 48-year-old female, was admitted to this hospital with a chief complaint of gait disturbance that had developed over the previous four months. On admission she was noted to have a slight dimunition of her mental capacity, a rigidity of her extremities (more pronounced in the lower limbs), and akinesia, though no tremor. CT scans revealed extensive areas of calcification in the central nervous system, encompassing the cerebral basal ganglia (corpus striatum), the cerebellum, the midbrain, and the gray and white matter of the cerebrum. There was no evidence of calcification in the spinal cord. Physical and laboratory examinations did not yield any findings suggestive of abnormalities in calcium metabolism, nor was there any indication that her condition was of a familial nature. The case was concluded, therefore, to be idiopathic. Amelioration in the symptoms occurred following the administration of L-dopa. (author)

Forced normalization has been reported in association with almost all anti-epileptic drugs. We report on a 9-year-old girl with idiopathic epilepsy who showed forced normalization after administration of levetiracetam (LEV). She initially presented with generalized tonic-clonic seizures when she was 4 years old. Diffuse sharp and slow wave complexes (SWCs) were observed on electroencephalography (EEG). We prescribed sodium valproate (VPA) and benzodiazepines, but the seizures and EEG findings worsened gradually. Although subsequent administration of LEV stopped the seizures, the patient became subject to episodes of rage and violent behavior. Forced normalization was confirmed by the disappearance of SWCs on EEG. We reduced the dose of LEV and tried in various ways to resolve the situation, but finally we had to abandon LEV. To the best of our knowledge, this is the first report of a patient with idiopathic epilepsy but without disabilities in everyday life showing forced normalization associated with LEV administration.

Idiopathic portal hypertension with regard to thiopurine treatment.

Science.gov (United States)

Machlab, Salvador; Miquel, Mireia; Vergara, Mercedes

2018-04-16

Idiopathic portal hypertension (IPH) is an infrequent adverse reaction to the use of thiopurines that tends to be overlooked. Herein, we present a patient with ileocolic Crohn's disease treated with azathioprine who presented ascites, esophageal varices and splenomegaly without any signs of liver cirrhosis. A portal hemodynamics study revealed a normal portosystemic gradient compatible with presinusoidal portal hypertension. Finally, IPH was diagnosed after a liver biopsy. IPH secondary to thiopurines is due to a 6-thioguanine nucleotide (6-TGN)-dependent reaction and occurs predominantly between three months and three years after the start of treatment. The onset is usually insidious and thrombocytopenia is the first manifestation. The definitive diagnosis is obtained by liver biopsy.

Management of idiopathic pulmonary fibrosis: selected case reports

Full Text Available In 2011, revised international guidelines were issued jointly by the American Thoracic Society, the European Respiratory Society, the Japanese Respiratory Society and the Latin American Thoracic Association, which provide a valuable framework for the diagnosis and management of idiopathic pulmonary fibrosis (IPF. However, due to the complexity of IPF, these guidelines may not comprehensively account for the management of individual IPF patients in clinical practice. We describe three patient cases that were presented and discussed during the 2013 AIR: Advancing IPF Research meeting in Nice, France. These cases highlight the heterogeneity in the presentation, history and clinical course of IPF, together with expert insights regarding the diagnosis and management of IPF in the real-life setting.

Chylopericardium rarely occurs in pediatric patients, but when it does it is most often a result of lymphatic injury during cardiothoracic surgery. Primary idiopathic chylopericardium is especially rare, with few cases in the pediatric literature. We report a 10-year-old boy who presented with primary idiopathic chylopericardium after unsuccessful initial treatment with surgical lymphatic ligation and creation of a pericardial window. Following readmission to the hospital for a right-side chylothorax resulting from the effluent from the pericardial window, he had successful treatment by interventional radiology with percutaneous thoracic duct embolization. This case illustrates the utility of thoracic duct embolization as a less-invasive alternative to surgical thoracic duct ligation, or as a salvage procedure when surgical ligation fails. (orig.)

Idiopathic normal pressure hydrocephalus is a syndrome, which typically has a clinical presentation of gait/balance disturbance, often accompanied by cognitive decline and/or urinary incontinence. Its diagnosis is based on relevant history and clinical examination, appropriate imaging findings and physiological testing. The clinical picture of idiopathic normal pressure hydrocephalus may occasionally be difficult to distinguish from that of Alzheimer's dementia, subcortical ischemic vascular dementia and Parkinson's disease. The aim of this article is to systematically review the literature from the last 29 years in order to identify cerebrospinal fluid (CSF) or imaging biomarkers that may aid in the diagnosis of the syndrome. The authors concluded that no CSF or imaging biomarker is currently fulfilling the criteria required to aid in the diagnosis of the condition. However, a few studies have revealed promising CSF and imaging markers that need to be verified by independent groups. The reasons that the progress in this field has been slow so far is also commented on, as well as steps required to apply the current evidence in the design of future studies within the field.

The Immune Response and the Pathogenesis of Idiopathic Inflammatory Myositis: a Critical Review.

Ceribelli, Angela; De Santis, Maria; Isailovic, Natasa; Gershwin, M Eric; Selmi, Carlo

2017-02-01

The pathogenesis of idiopathic inflammatory myositis (IIMs, including polymyositis and dermatomyositis) remains largely enigmatic, despite advances in the study of the role played by innate immunity, adaptive immunity, genetic predisposition, and environmental factors in an orchestrated response. Several factors are involved in the inflammatory state that characterizes the different forms of IIMs which share features and mechanisms but are clearly different with respect to the involved sites and characteristics of the inflammation. Cellular and non-cellular mechanisms of both the immune and non-immune systems have been identified as key regulators of inflammation in polymyositis/dermatomyositis, particularly at different stages of disease, leading to the fibrotic state that characterizes the end stage. Among these, a special role is played by an interferon signature and complement cascade with different mechanisms in polymyositis and dermatomyositis; these differences can be identified also histologically in muscle biopsies. Numerous cellular components of the adaptive and innate immune response are present in the site of tissue inflammation, and the complexity of idiopathic inflammatory myositis is further supported by the involvement of non-immune mechanisms such as hypoxia and autophagy. The aim of this comprehensive review is to describe the major pathogenic mechanisms involved in the onset of idiopathic inflammatory myositis and to report on the major working hypothesis with therapeutic implications.

2015-01-01

Idiopathic granulomatous mastitis (IGM) is a benign, aseptic inflammatory disease of unknown origin, which must be distinguished from tumoral and infectious processes that affect the breast, including tuberculosis. IGM is a rare cause of erythema nodosum, but it is useful for dermatologists to be aware of this association. A 32-year-old nulliparous woman presented with erythema nodosum, arthralgia and fever. On examination, she had a firm and painful mass of 5cm in the right breast with retraction and axillary adenopathy. The breast lump developed gradually over the preceding 4 months. Although two biopsies showed no evidence of atypical cells, inflammatory areas and a granulomatous process were seen. Culture of breast tissue for mycobacteria was negative. A diagnostic of idiopathic granulomatous mastitis was made. Systemic corticosteroids led to a reduction in size of the mass, but relapse occurred in the contralateral breast on dose-reduction of the corticosteroids. IGM is a rare disease of unknown aetiology. Diagnosis is based on characteristic histological features and exclusion of other granulomatous diseases. Extra-mammary signs are rare and include erythema nodosum, arthralgia and episcleritis. Management is poorly codified. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

epigenetic factors involved that might also explain low observed twin concordance? The genetic (and epigenetic) models for different IFEs, their comorbidities, and their similarities to other neurodevelopmental disorders deserve investigation in the coming years. In so doing, we will probably learn much about normal brain functioning. This is because these disorders, perhaps more than any other human brain disease, are disorders of functional brain systems (even though these functional networks may not yet be fully defined). In June 2012, an international group of clinical and basic science researchers met in London under the auspices of the Waterloo Foundation to discuss and debate these issues in relation to IFEs. This Waterloo Foundation Symposium on the Idiopathic Focal Epilepsies: Phenotype to Genotype witnessed presentations that explored the clinical phenomenology, phenotypes and endophenotypes, and genetic approaches to investigation of these disorders. In parallel, the impact of these epilepsies on children and their families was reviewed. The papers in this supplement are based upon these presentations. They represent an updated state-of-the-art thinking on the topics explored. The symposium led to the formation of international working groups under the umbrella of "Luke's Idiopathic Focal Epilepsy Project" to investigate various aspects of the idiopathic focal epilepsies including: semiology and classification, genetics, cognition, sleep, high-frequency oscillations, and parental resources (see www.childhood-epilepsy.org). The next sponsored international workshop, in June 2014, was on randomised controlled trials in IFEs and overnight learning outcome measures.

Full Text Available Gingival enlargements are of many types and vary according to the etiologic factors and pathologic processes that produce them. Though there are many classifications of gingival enlargement, the most practical one is as follows: 1 Inflammatory gingival enlargement 2 Fibrous gingival hyperplasia 3 Combination of inflammatory and fibrous hyperplasia. Gingival hyperplasia is a heterogeneous group of disorder, which appears clinically as diffuse, firm, and massive enlargement of the gingiva covering most of the crown of the teeth. Idiopathic gingival enlargement is a rare condition of undetermined etiology, although some cases have definite hereditary basis. A case of unilateral idiopathic fibrous gingival hyperplasia on left side of both the jaws with severe bone resorption is presented.

Atherosclerosis in Juvenile Idiopathic Arthritis

Full Text Available Atherosclerosis is a chronic inflammatory disease of the arteries. Clinical consequences of the atherosclerotic process occur in the adult population, however atherosclerotic process begins in childhood. The classic risk factors for atherosclerosis include obesity, dyslipidaemia, age, gender or family history. In recent years, attention has been drawn to the similarity between atherosclerotic inflammatory processes and inflammatory changes in the course of systemic connective tissue disease, in particular systemic lupus etythematosus (SLE or rheumatoid arthritis (RA. There is also observed the similarity of the pathogenetic background of development of atherosclerosis and juvenile idiopathic arthritis (JIA. Elevated levels of pro-inflammatory cytokines are observed in the course of juvenile idiopathic arthritis. Also homocysteine concentrations, which may play a significant role in the development of atherosclerotic lesions, are observed higher in patients with JIA. Some studies revealed higher carotid intima-media thickness (IMT index values in children with JIA. In view of the fact that atherosclerotic process begins as early as in childhood, the introduction of appropriate preventive measures in children is a matter of utmost importance.

Idiopathic epilepsies are considered to have relatively good prognoses and normal or near normal developmental outcomes. Nevertheless, accumulating studies demonstrate memory and psychosocial deficits in this population, and the prevalence, severity and relationships between these domains are still not well defined. We aimed to assess memory, psychosocial function, and the relationships between these two domains among children with idiopathic epilepsy syndromes using an extended neuropsychological battery and psychosocial questionnaires. Cognitive abilities, neuropsychological performance, and socioemotional behavior of 33 early adolescent children, diagnosed with idiopathic epilepsy, ages 9-14years, were assessed and compared with 27 age- and education-matched healthy controls. Compared to controls, patients with stabilized idiopathic epilepsy exhibited higher risks for short-term memory deficits (auditory verbal and visual) (pmemory deficits (plong-term memory deficits (pmemory deficits was related to severity of psychosocial symptoms among the children with epilepsy but not in the healthy controls. Results suggest that deficient auditory verbal memory may be compromising psychosocial functioning in children with idiopathic epilepsy, possibly underscoring that cognitive variables, such as auditory verbal memory, should be assessed and treated in this population to prevent secondary symptoms.

To date etiology of adolescent idiopathic scoliosis appears complex and still remains unclear. A distorted body schema has been proposed to be a part of a sequence of pathological events in the development of adolescent idiopathic scoliosis. To investigate the awareness of trunk misalignment in adolescents with idiopathic scoliosis. Information about 44 adolescents with idiopathic scoliosis was collected as follows: age; sex; handedness; family history of scoliosis; back pain; sport practice; shoulder and waist line symmetry; leg length; dorsal kyphosis; back hump; rehabilitation; scoliotic curve; Risser sign. We evaluated awareness of trunk misalignment with a graphic table displaying pictures of progressively increasing scoliotic curves. Patients were asked to indicate which picture corresponded to their perceived own spinal alignment. Patients with thoracolumbar scoliosis overestimated their actual thoracic spine curve. Patients with thoracic-thoracolumbar scoliosis underestimated their actual thoracolumbar spine curve and overestimated their actual lumbar spine curve. Scoliotic curve > 15°, double curve, younger age, back pain, family history of scoliosis and lower Risser score related with a misperception of trunk alignment. Our results support the hypothesis that adolescents with idiopathic scoliosis have an altered corporeal awareness of their trunk alignment.

A case of idiopathic omental hemorrhage

Full Text Available With the exception of trauma, intraperitoneal hemorrhage in young women is caused by the high frequency of ectopic pregnancy and ovarian bleeding. Here, we describe a case of idiopathic omental hemorrhage, which is a rare cause of intraperitoneal hemorrhage. Intraperitoneal hemorrhage was suspected in a 38-year-old Japanese woman based on contrast-enhanced computed tomography. Her last menstrual period was 23 days prior, and ovarian bleeding was considered based on bloody ascites revealed by culdocentesis. She underwent emergency surgery for hypovolemic shock. Although both ovaries were of normal size and no abnormal findings were observed, we performed a partial omentectomy because multiple clots were attached only to the greater omentum. Postoperatively, no rebleeding occurred, and she was discharged 11 days after the surgery. Because she did not have a clear history of trauma and underlying disease, idiopathic omental hemorrhage was diagnosed.

Full Text Available OBJECTIVES: The aims of this study were to measure levels of sleep, stress, and depression, as well as health-related quality of life, and to assess the neurocognitive profiles in a sample of adolescents with idiopathic musculoskeletal pain. METHODS: Nineteen adolescents with idiopathic musculoskeletal pain and 20 age-matched healthy control subjects were evaluated regarding their levels of sleep and stress, as well as quality of life, and underwent neurocognitive testing. RESULTS: The sample groups consisted predominantly of females (84%, and the socioeconomic status did not differ between the two groups. In addition, the occurrence of depressive symptoms was similar between the two groups; specifically, 26% of the idiopathic musculoskeletal pain patients and 30% of the control subjects had scores indicative of depression. Teenagers in the group with idiopathic musculoskeletal pain reported poorer quality of life and sleep scores than those in the control group. Regarding stress, patients had worse scores than the control group; whereas 79% of the adolescents with idiopathic musculoskeletal pain met the criteria for a diagnosis of stress, only 35% of the adolescents in the control group met the criteria. In both groups, we observed scores that classified adolescents as being in the resistance phase (intermediate and exhaustion phase (pathological of distress. However, the idiopathic musculoskeletal pain group more frequently reported symptomatic complaints of physical and emotional distress. The neurocognitive assessment showed no significant impairments in either group. CONCLUSION: Adolescents with idiopathic musculoskeletal pain did not exhibit cognitive impairments. However, adolescents with idiopathic musculoskeletal pain did experience intermediate to advanced psychological distress and lower health-related quality of life, which may increase their risk of cognitive dysfunction in the future.

Subvalvular aneurysms are the least common type of left ventricular (LV) aneurysms and can be fatal. Subaortic LV aneurysms are much rarer than submitral LV aneurysms and mostly reported in infancy. They can be congenital or acquired secondary to infections, cardiac surgery or trauma. Here, we report a unique presentation of a large, idiopathic subaortic aneurysm in an adult masquerading as an acute coronary syndrome. Diagnosis was made with the help of a CT aortography. Aneurysm was surgically resected with good results. This case highlights the clinical presentation and management of subaortic aneurysms, an important differential for congenital aortic malformations. 2016 BMJ Publishing Group Ltd.

Idiopathic granulomatous mastitis (IGM) is an uncommon chronic inflammatory lesion of the breast with an uncertain optimal treatment regimen, the physical examination, and radiologic features of which may be confused with breast carcinoma. In this study, we aimed to describe the clinicopathologic characteristics of 33 patients who admitted to our breast policlinic and took the diagnosis of granulomatous (idiopathic and non-idiopathic) mastitis, and report the place of corticosteroids and the timing of surgery in the treatment of patients with IGM. The clinical features of 33 patients who presented to our breast policlinic with the complaint of breast mass and reached the final diagnosis of GM between March 2005 and October 2009 were reported. The most common symptoms were mass (n: 27) and pain (n: 11). Ultrasonography (USG) and biopsy were performed in all of the patients. Mammography (MMG) was performed in 9, and magnetic resonance imaging (MRI) in 10 patients. The diagnosis of idiopathic lobular granulomatous mastitis (ILGM) was made in 25 patients and tuberculous mastitis (non-idiopathic GM) in the remaining 8 patients. Twenty-four patients received steroid treatment except one who was pregnant. After giving birth, she also received steroids. One of the patients who developed recurrence after 11 months repeated the steroid therapy. Eight patients with tuberculous mastitis were placed on a regimen of antituberculosis therapy for 6 months. In the diagnosis of IGM, physical examination, USG, MMG, and even MRI alone may sometimes not be enough. They should be discussed altogether and the treatment should begin after definitive histopathologic result. Fine needle aspiration biopsy for cytology will result in a high level of diagnostic accuracy, however, core biopsy will reinforce the exact result. Corticosteroid therapy has been shown to be efficacious for IGM, but in the existence of complications such as abscess formation, fistulae, and persistent wound infection

Growth differentiation factor 15 (GDF15) is a pleiotropic cytokine that belongs to the transforming growth factor-β superfamily. Elevated serum concentrations of this cytokine have been reported in patients with various malignancies. To assess the potential roles of GDF15 in hematologic malignancies, we measured its serum levels in patients with these diseases. We found that serum GDF15 levels were elevated in almost all these patients, particularly in patients with primary myelofibrosis (PMF). Immunohistochemical staining of bone marrow (BM) specimens revealed that GDF15 was strongly expressed by megakaryocytes, which may be sources of increased serum GDF15 in PMF patients. Therefore, we further assessed the contribution of GDF15 to the pathogenesis of PMF. Recombinant human (rh) GDF15 enhanced the growth of human BM mesenchymal stromal cells (BM-MSCs), and it enhanced the potential of these cells to support human hematopoietic progenitor cell growth in a co-culture system. rhGDF15 enhanced the growth of human primary fibroblasts, but it did not affect their expression of profibrotic genes. rhGDF15 induced osteoblastic differentiation of BM-MSCs in vitro, and pretreatment of BM-MSCs with rGDF15 enhanced the induction of bone formation in a xenograft mouse model. These results suggest that serum levels of GDF15 in PMF are elevated, that megakaryocytes are sources of this cytokine in BM, and that GDF15 may modulate the pathogenesis of PMF by enhancing proliferation and promoting osteogenic differentiation of BM-MSCs

Idiopath=ic Granulomatous Lobular Mastitis Masquerading as a Breast Tumor: A Case Report.

Idiopathic granulomatous lobular mastitis (IGLM) is an inflammatory disease of the breast with an obscure etiology. It occurs mainly in women of reproductive age, and the lesion mimics carcinoma of the breast both clinically and radiologically. We present the case of a 29-year-old female who visited our hospital in Kancheepuram, Tamil Nadu, with a 4 × 3 cm lump in the upper outer quadrant of her left breast. The clinical and radiological findings were indicative of a malignant lesion; however, fine-needle aspiration cytology (FNAC) revealed features of granulomatous mastitis, and the subsequent histology of the excised lump confirmed the diagnosis of IGLM. IGLM should be considered as one of the differential diagnoses when granulomas are encountered in breast FNAC and biopsy. A definitive diagnosis of IGLM can be made by identifying its characteristic histomorphology and ruling out other causes for granulomatous inflammation. An exact diagnosis is essential since the treatment for different granulomatous conditions of the breast varies.

Our findings suggest a rare variant in CELSR2 as causative for idiopathic scoliosis in a family with dominant segregation and further highlight common variation in CELSR2 in general susceptibility to idiopathic scoliosis in the Swedish......-Danish population. Both variants are located in the highly conserved GAIN protein domain, which is necessary for the auto-proteolysis of CELSR2, suggesting its functional importance....

Among the three classic Philadelphia chromosome-negative myeloproliferative neoplasms, primary myelofibrosis (PMF) is the most severe in terms of disease biology, survival and quality of life. Abnormalities in the process of differentiation of PMF megakaryocytes (MKs) are a hallmark of the disease. Nevertheless, the molecular events that lead to aberrant megakaryocytopoiesis have yet to be clarified. Protein kinase Cɛ (PKCɛ) is a novel serine/threonine kinase that is overexpressed in a variety of cancers, promoting aggressive phenotype, invasiveness and drug resistance. Our previous findings on the role of PKCɛ in normal (erythroid and megakaryocytic commitment) and malignant (acute myeloid leukemia) hematopoiesis prompted us to investigate whether it could be involved in the pathogenesis of PMF MK-impaired differentiation. We demonstrate that PMF megakaryocytic cultures express higher levels of PKCɛ than healthy donors, which correlate with higher disease burden but not with JAK2V617F mutation. Inhibition of PKCɛ function (by a negative regulator of PKCɛ translocation) or translation (by target small hairpin RNA) leads to reduction in PMF cell growth, restoration of PMF MK differentiation and inhibition of PKCɛ-related anti-apoptotic signaling (Bcl-xL). Our data suggest that targeting PKCɛ directly affects the PMF neoplastic clone and represent a proof-of-concept for PKCɛ inhibition as a novel therapeutic strategy in PMF.

Single night postoperative prone posturing in idiopathic macular hole surgery.

LENUS (Irish Health Repository)

2012-02-01

Purpose. To evaluate the role of postoperative prone posturing for a single night in the outcome of trans pars plana vitrectomy (TPPV) with internal limiting membrane (ILM) peel and 20% perfluoroethane (C2F6) internal tamponade for idiopathic macular hole. Methods. This prospective trial enrolled 14 eyes in 14 consecutive patients with idiopathic macular hole. All eyes underwent TPPV with vision blue assisted ILM peeling with and without phacoemulsification and intraocular lens (IOL) for macular hole. Intraocular gas tamponade (20% C2F6) was used in all cases with postoperative face-down posturing overnight and without specific posturing afterwards. LogMAR visual acuity, appearance by slit-lamp biomicroscopy, and ocular coherence tomography (OCT) scans were compared preoperatively and postoperatively to assess outcome. Results. Among 14 eyes recruited, all eyes were phakic; 50% of patients underwent concurrent phacoemulsification with IOL. The macular holes were categorized preoperatively by OCT appearance, 4 (28.57%) were stage 2, 7 (50%) were stage 3, and 3 (21.43%) were stage 4. Mean macular hole size was 0.35 disk diameters. Symptoms of macular hole had been present for an average of 6.5 months. All holes (100%) were closed 3 and 6 months postoperatively. Mean visual acuity (logMAR) was improved to 0.61 at 3 months and was stable at 6 months after the surgery. None of the eyes had worse vision postoperatively. Conclusions. Vitrectomy with ILM peeling and 20% C2F6 gas with a brief postoperative 1 night prone posturing regimen is a reasonable approach to achieve anatomic closure in idiopathic macular hole. Concurrent cataract extraction did not alter outcomes and was not associated with any additional complications.

The glymphatic system has in previous studies been shown as fundamental to clearance of waste metabolites from the brain interstitial space, and is proposed to be instrumental in normal ageing and brain pathology such as Alzheimer's disease and brain trauma. Assessment of glymphatic function using magnetic resonance imaging with intrathecal contrast agent as a cerebrospinal fluid tracer has so far been limited to rodents. We aimed to image cerebrospinal fluid flow characteristics and glymphatic function in humans, and applied the methodology in a prospective study of 15 idiopathic normal pressure hydrocephalus patients (mean age 71.3 ± 8.1 years, three female and 12 male) and eight reference subjects (mean age 41.1 + 13.0 years, six female and two male) with suspected cerebrospinal fluid leakage (seven) and intracranial cyst (one). The imaging protocol included T1-weighted magnetic resonance imaging with equal sequence parameters before and at multiple time points through 24 h after intrathecal injection of the contrast agent gadobutrol at the lumbar level. All study subjects were kept in the supine position between examinations during the first day. Gadobutrol enhancement was measured at all imaging time points from regions of interest placed at predefined locations in brain parenchyma, the subarachnoid and intraventricular space, and inside the sagittal sinus. Parameters demonstrating gadobutrol enhancement and clearance in different locations were compared between idiopathic normal pressure hydrocephalus and reference subjects. A characteristic flow pattern in idiopathic normal hydrocephalus was ventricular reflux of gadobutrol from the subarachnoid space followed by transependymal gadobutrol migration. At the brain surfaces, gadobutrol propagated antegradely along large leptomeningeal arteries in all study subjects, and preceded glymphatic enhancement in adjacent brain tissue, indicating a pivotal role of intracranial pulsations for glymphatic function.

To describe clinical signs, diagnostic findings, and outcome in dogs with idiopathic intrahepatic portal hypertension. Retrospective study. 33 dogs. Medical records of dogs with portal hypertension of intra-abdominal origin were reviewed. Dogs with intra-abdominal portal hypertension of vascular causes or with hepatic histopathologic changes consistent with severe diffuse hepatobiliary disease were excluded. History and results of physical examination, clinicopathologic tests, diagnostic imaging studies, histologic examination, and treatment were summarized. Outcome was determined in 26 dogs. Dogs were referred most often because of ascites, intermittent vomiting or diarrhea, and polydipsia of several months' duration. Microcytosis, high serum alkaline phosphatase and alanine transaminase activities, hepatic dysfunction, urine specific gravity anastomoses were the major findings of diagnostic imaging. Hepatic histopathologic changes were consistent with idiopathic noncirrhotic portal hypertension and were indistinguishable from those of dogs with surgically created portocaval anastomosis. Outcome was determined for 19 dogs released from hospital; 13 dogs remained healthy with mostly palliative treatment for periods of 5 months to 9 years. The clinical signs, clinicopathologic test results, portal pressure, and gross appearance of the liver of dogs with idiopathic noncirrhotic portal hypertension may be identical to those of dogs with cirrhosis; therefore liver biopsy is crucial. Because the prognosis for idiopathic noncirrhotic portal hypertension is generally favorable, owners of affected dogs should be discouraged from choosing euthanasia.

TREATMENT APPROACH FOR JUVENILE IDIOPATHIC ARTHRITIS-RELATED UVEITIS: 2012 UPDATE

Directory of Open Access Journals (Sweden)

Francesco Zulian

2012-01-01

Full Text Available Chronic anterior uveitis is the most common extra-articular complication of juvenile idiopathic arthritis. It is more frequent in the early onset forms with a higher prevalence in the oligoarticular (40% than in other juvenile idiopathic arthritis subtypes (5–14%. The risk for severe visual impairment is still high due to the development of sight-threatening complications (synechiae, band keratopathy, cataract, glaucoma, cystoid macular oedema. Treatment is not standardized and requires a complex decision-making process, involving a close collaboration between paediatric ophthalmologist and rheumatologist. Topical therapy alone is often inadequate to control ocular inflammation and bulbar injections are too invasive to perform in children therefore immunosuppressive treatment is often advocated. Low dose methotrexate is the second-line agent mostly used although no controlled studies comparing effects of early to late methotrexate treatment have been reported. Mycophenolate mofetil is effective in controlling inflammation in methotrexate -refractory patients. Its efficacy, however, seems to be more relevant in intermediate or posterior uveitis, than in juvenile idiopathic arthritis uveitis and scleritis. Anti-TNFα agents, namely infliximab and adalimimab showed effectiveness in open-label studies but no wide controlled trials have been reported so far. Adalimimab is as effective as infliximab but has an easier way of administration and a better drug tolerance. Abatacept should be used in anti-TNF refractory patients with juvenile idiopathic arthritis uveitis.

Pulsatile tinnitus is experienced by most patients with idiopathic intracranial hypertension. The pathophysiology remains uncertain; however, transverse sinus stenosis and sigmoid sinus diverticulum/dehiscence have been proposed as potential etiologies. We aimed to determine whether the prevalence of transverse sinus stenosis and sigmoid sinus diverticulum/dehiscence was increased in patients with idiopathic intracranial hypertension and pulsatile tinnitus relative to those without pulsatile tinnitus and a control group. CT vascular studies of patients with idiopathic intracranial hypertension with pulsatile tinnitus ( n = 42), without pulsatile tinnitus ( n = 37), and controls ( n = 75) were independently reviewed for the presence of severe transverse sinus stenosis and sigmoid sinus diverticulum/dehiscence according to published criteria. The prevalence of transverse sinus stenosis and sigmoid sinus diverticulum/dehiscence in patients with idiopathic intracranial hypertension with pulsatile tinnitus was compared with that in the nonpulsatile tinnitus idiopathic intracranial hypertension group and the control group. Further comparisons included differing degrees of transverse sinus stenosis (50% and 75%), laterality of transverse sinus stenosis/sigmoid sinus diverticulum/dehiscence, and ipsilateral transverse sinus stenosis combined with sigmoid sinus diverticulum/dehiscence. Severe bilateral transverse sinus stenoses were more frequent in patients with idiopathic intracranial hypertension than in controls ( P tinnitus within the idiopathic intracranial hypertension group. Sigmoid sinus dehiscence (right- or left-sided) was also more common in patients with idiopathic intracranial hypertension compared with controls ( P = .01), but there was no significant association with pulsatile tinnitus within the idiopathic intracranial hypertension group. While our data corroborate previous studies demonstrating increased prevalence of sigmoid sinus diverticulum

Adrenocorticotropic hormone (ACTH) has shown efficacy as primary and secondary therapy for nephrotic syndrome due to membranous nephropathy. The data on using ACTH to treat idiopathic FSGS are limited. This report describes our experience using ACTH for nephrotic syndrome due to idiopathic FSGS in the United States. Twenty-four patients with nephrotic syndrome from idiopathic FSGS were treated with ACTH gel at two academic medical centers between 2009 and 2012, either as part of investigator-initiated pilot studies (n=16) or by prescription for treatment-resistant FSGS (n=8). The primary outcome was remission of proteinuria. The median dose of ACTH was 80 units injected subcutaneously twice weekly. Treatment durations were not uniform. Twenty-two patients had received immunosuppression (mean, 2.2 medications) before ACTH therapy. Six patients had steroid-dependent and 15 had steroid-resistant FSGS. At the time of ACTH initiation, the median serum creatinine (interquartile range) was 2.0 (1.1-2.7) mg/dl, estimated GFR was 36 (28-78) ml/min per 1.73 m(2), and urine protein-to-creatinine ratio was 4595 (2200-8020) mg/g. At the end of ACTH therapy, 7 of 24 patients (29%) experienced remission (n=2 complete remissions, n=5 partial remissions). All remitters had steroid-resistant (n=5) or steroid-dependent (n=2) FSGS. Two responders relapsed during the follow-up period (mean ± SD, 70±31 weeks). Adverse events occurred in 21 of 24 patients, including one episode of new-onset diabetes that resolved after stopping ACTH and two episodes of AKI. Response to ACTH treatment among steroid-resistant or steroid-dependent patients with FSGS is low, but ACTH gel may be a viable treatment option for some patients with resistant nephrotic syndrome due to idiopathic FSGS. Further research is necessary to determine which patients will respond to therapy.

Coexistence of chronic renal failure, hashimoto thyroiditis and idiopathic hypoparathyroidism: a rare case report.

2014-04-01

Hypoparathyroidism is an uncommon disease and its coexistence with chronic renal failure is quite rare. Hypocalcemia and hyperphosphatemia are seen in both diseases. Diagnosis of hypoparathyroidism may be overlooked when parathormone response is not evaluated in patients with chronic renal failure. A 19-year-old female patient who had been receiving hemodialysis for 3 years because of chronic renal failure was diagnosed as idiopathic hypoparathyroidism and hashimoto thyroiditis. When her medical records on the first admission and medical history were evaluated, hypoparathyroidism and hashimoto thyroiditis were seen to be present also when she was started hemodialysis. Idiopathic hypoparathyroidism should be suspected in case as absence of parathormone response to hypocalcemia in patients with chronic renal failure. It should be taken into consideration that hashimoto thyroiditis may accompany and required analysis should be done.

Single-surgeon series investigating the learning curve involved in surgery for spinal deformity may be confounded by changes in technology and techniques. Our objective with this multicenter, prospective study was to present a cross-sectional analysis of the impact of surgeon experience on surgery for adolescent idiopathic scoliosis. All posterior-only surgical procedures for adolescent idiopathic scoliosis performed in the 2007 to 2008 academic year, with a minimum of two years of patient follow-up, were included. Two groups were created on the basis of surgeon experience: a young surgeons' group, which included patients of surgeons with less than five years of experience, and an experienced surgeons' group, which included patients of surgeons with five or more years of experience. Nine surgeons (four young and five experienced) operated on a total of one hundred and sixty-five patients with adolescent idiopathic scoliosis. The surgeons' experience ranged from less than one year to thirty-six years in practice. The two groups had similar preoperative curve-magnitude measurements, SRS-22 (Scoliosis Research Society-22) scores, and distribution by Lenke curve type. There were significant operative and postoperative differences. The young surgeons fused an average of 1.2 levels more than the experienced surgeons (p = 0.045). The mean intraoperative estimated blood loss (EBL) of the young surgeons' group was more than twice that of the experienced surgeons' group (2042 mL compared with 1013 mL; p self-image (p = 0.008), and function (p adolescent idiopathic scoliosis were significantly and positively correlated with surgeon experience.

The juvenile idiopathic inflammatory myopathies (JIIM) are systemic autoimmune diseases characterized by skeletal muscle weakness, characteristic rashes, and other systemic features. In follow-up to our study defining the major clinical subgroup phenotypes of JIIM, we compared demographics, clinical features, laboratory measures, and outcomes among myositis-specific autoantibody (MSA) subgroups, as well as with published data on adult idiopathic inflammatory myopathy patients enrolled in a separate natural history study. In the present study, of 430 patients enrolled in a nationwide registry study who had serum tested for myositis autoantibodies, 374 had either a single specific MSA (n = 253) or no identified MSA (n = 121) and were the subject of the present report. Following univariate analysis, we used random forest classification and exact logistic regression modeling to compare autoantibody subgroups. Anti-p155/140 autoantibodies were the most frequent subgroup, present in 32% of patients with juvenile dermatomyositis (JDM) or overlap myositis with JDM, followed by anti-MJ autoantibodies, which were seen in 20% of JIIM patients, primarily in JDM. Other MSAs, including anti-synthetase, anti-signal recognition particle (SRP), and anti-Mi-2, were present in only 10% of JIIM patients. Features that characterized the anti-p155/140 autoantibody subgroup included Gottron papules, malar rash, "shawl-sign" rash, photosensitivity, cuticular overgrowth, lowest creatine kinase (CK) levels, and a predominantly chronic illness course. The features that differed for patients with anti-MJ antibodies included muscle cramps, dysphonia, intermediate CK levels, a high frequency of hospitalization, and a monocyclic disease course. Patients with anti-synthetase antibodies had higher frequencies of interstitial lung disease, arthralgia, and "mechanic's hands," and had an older age at diagnosis. The anti-SRP group, which had exclusively juvenile polymyositis, was characterized by high

The aim of this article is to study the evidence-based knowledge related to the use of biological therapies in patients diagnosed with idiopathic inflammatory myopathy (dermatomyositis, polymyositis and inclusion body myositis). In this review the leading published studies related to the use of biological therapy in patients with myositis are analysed; mainly those with high methodological standards, that means randomized and controlled studies. Methodological drawbacks due to the rarity and heterogeneity of these complex diseases are also addressed. Up to now is not possible to ascertain the biologics as a recommended therapy in patients with myositis, at least based in the current evidence-based knowledge, although it can not be neglected as a therapeutic option in some clinical situations, taking into account the scarce of effective treatments in those patients, especially in refractory myositis. Future studies probably will help to better define the role of biological therapies in patients with idiopathic inflammatory myopathy. Copyright © 2013 Elsevier España, S.L.U. All rights reserved.

To clarify the time course of recovery in patients with idiopathic vocal fold paralysis. Retrospective chart review. Medical records for all patients with idiopathic vocal fold paralysis over a 10-year period were reviewed to obtain demographic and clinical information, including onset of disease and recovery of vocal function. Stroboscopic exams of patients who recovered voice were reviewed blindly to assess return of vocal fold motion. Thirty-eight of 55 patients (69%) recovered vocal function. Time course of recovery could be assessed in 34 patients who did not undergo injection augmentation. The mean time to recovery was 152.8 ± 109.3 days (left, 179.8 ± 111.3 days; right, 105.3 ± 93.7 days; P = .088). Two-thirds of patients recovered within 6 months. Probability of recovery declined over time. Five of 22 patients who recovered voice had return of vocal fold motion; 17 did not. The mean time to recovery did not differ between these groups (return of motion, 127.4 ± 132.3 days; no return of motion, 160.1 ± 105.1 days; P = .290). Sixty-nine percent of patients with idiopathic vocal fold paralysis recovered vocal function, two-thirds doing so within 6 months of onset. Age, gender, laterality, use of injection augmentation did not influence recovery rate. Declining probability of recovery over time leads us to consider framework surgery after 6 months in patients with idiopathic paralysis. 4.

Growth factors in idiopathic pulmonary fibrosis: relative roles

Directory of Open Access Journals (Sweden)

Allen Jeremy T

2001-11-01

Full Text Available Abstract Treatment of idiopathic pulmonary fibrosis patients has evolved very slowly; the fundamental approach of corticosteroids alone or in combination with other immunosuppressive agents has had little impact on long-term survival. The continued use of corticosteroids is justified because of the lack of a more effective alternative. Current research indicates that the mechanisms driving idiopathic pulmonary fibrosis reflect abnormal, dysregulated wound healing within the lung, involving increased activity and possibly exaggerated responses by a spectrum of profibrogenic growth factors. An understanding of the roles of these growth factors, and the way in which they modulate events at cellular level, could lead to more targeted therapeutic strategies, improving patients' quality of life and survival.

Porte, M; Patte, K; Dupeyron, A; Cottalorda, J

Many practitioners, pediatricians, and general practitioners prescribe physical therapy when tracking scoliosis. However, has physical therapy alone proved its efficacy in the care of the scoliosis to slow down progression? Our purpose is to report the results of a literature review on the effectiveness of rehabilitation in idiopathic scoliosis. No current study presents sufficient scientific proof to validate the efficacy of isolated exercise therapy in scoliosis. Learned societies recognize, however, the efficacy of combining conservative therapy (brace+physiotherapy) in idiopathic scoliosis. Should we then still prescribe rehabilitation without brace treatment? Although physical therapy alone does not seem effective in treating scoliosis, it can limit potential painful phenomena and be beneficial for respiratory function. The physical therapist can also teach the teenager the classic principles of hygiene of the back. It may therefore be appropriate to prescribe physical therapy, but the principles and objectives must be explained to the patient and family in light of current evidence-based medicine.

Idiopathic granulomatous mastitis: case report and review of the literature.

1997-08-01

We report a case of idiopathic granulomatous mastitis in a 35-year-old Japanese woman, who came to our hospital complaining of a tender mass in her right breast. Because the results of initial aspiration cytology were considered highly suspicious for carcinoma, modified radical mastectomy was performed. However, the final histological diagnosis was granulomatous lobular mastitis with no evidence of malignancy. Idiopathic granulomatous mastitis is a rare inflammatory breast disease of unknown etiology. Since the clinical manifestations are similar to those of mammary carcinoma, this condition has been misdiagnosed as carcinoma and treated as such. A review of the literature revealed that idiopathic granulomatous mastitis has tended to occur in young patients with a history of childbirth or oral contraceptive usage. Clinical or imaging diagnosis has often been difficult. Complete resection or corticosteroid therapy can be recommended as the optimal treatment. Since 38% of patients experience recurrence, long-term follow-up is indicated.

Cellular and molecular basis of chronic constipation: taking the functional/idiopathic label out.

In recent years, the improvement of technology and the increase in knowledge have shifted several strongly held paradigms. This is particularly true in gastroenterology, and specifically in the field of the so-called "functional" or "idiopathic" disease, where conditions thought for decades to be based mainly on alterations of visceral perception or aberrant psychosomatic mechanisms have, in fact, be reconducted to an organic basis (or, at the very least, have shown one or more demonstrable abnormalities). This is particularly true, for instance, for irritable bowel syndrome, the prototype entity of "functional" gastrointestinal disorders, where low-grade inflammation of both mucosa and myenteric plexus has been repeatedly demonstrated. Thus, researchers have also investigated other functional/idiopathic gastrointestinal disorders, and found that some organic ground is present, such as abnormal neurotransmission and myenteric plexitis in esophageal achalasia and mucosal immune activation and mild eosinophilia in functional dyspepsia. Here we show evidence, based on our own and other authors' work, that chronic constipation has several abnormalities reconductable to alterations in the enteric nervous system, abnormalities mainly characterized by a constant decrease of enteric glial cells and interstitial cells of Cajal (and, sometimes, of enteric neurons). Thus, we feel that (at least some forms of) chronic constipation should no more be considered as a functional/idiopathic gastrointestinal disorder, but instead as a true enteric neuropathic abnormality.

Idiopathic normal pressure hydrocephalus is usually observed in adults over 60 years of age. The highest incidence of cases is between 70 and 80 years-old, and it could be under-diagnosed in over 80 year-olds. A description is presented on the overall incidence and age group incidence, the delay in the diagnosis, and main outcomes. A descriptive study was performed on patients with idiopathic normal pressure hydrocephalus, in the population of Osona County during the years 2010-2015. The annual incidence rate was 4.43 per 100,000 inhabitants. The incidence increased with age; from 8.09 per 100,000 in the 60 to 69 years age group, to 23.61 per 100,000 in the 70-79 years age group of, and to 37.02 per 100,000 in the 80-89 years age. The delay in the diagnosis was 15.01 ± 10.35 months. All the patients improved after surgery, but only 73.3% of the patients maintained the improvement after one year. Idiopathic normal pressure hydrocephalus is an age related disease and probably underdiagnosed in the elderly. An early diagnosis and a clinical suspicion are essential in patients over 80 years old.

The incidence of lung cancer in patients with idiopathic pulmonary fibrosis(lPF) is higher than that of general population. To evaluate the frequency and CT findings of lung cancer associated with idiopathic pulmonary fibrosis, we analyzed 19 patients with lung cancer associated with idiopathic pulmonary fibrosis. We analyzed retrospectively 19 patients with histologically confirmed lung cancer out of 208 patients diagnosed as IPF either by CT and clinical findings(n=188) or histologically(n=20). All 19 patients were male, aged 40-85 years (mean 66 years). Scanning techniques were conventional CT in 12 patients, HRCT in 1 patient and both conventional CT and HRCT in 6 patients. We analyzed the CT patterns of lung cancer and IPF, locations of the tumor and histologic types of lung cancer. The incidence of lung cancer in patients with idiopathic pulmonary fibrosis was 9.1%(19/208). In 11 of 19 patients, CT findings of lung cancer were ill-defined consolidation-like mass. Lung cancer was located mainly in lower lobes(right lower lobe; 10/19, left lower lobe; 5/19) and at the periphery(12/19). Histologically, squamous cell carcinoma was the most common cell type (11/19). The incidence of lung cancer in patients with idiopathic pulmonary fibrosis was much higher than that of general population. Typical CT findings of lung cancer were predominantly ill-defined consolidation like mass at the peripheral lung portion which is the location where the most advanced fibrosis occur.

Full Text Available Background: Several studies have suggested higher incidence of osteoporosis in patients with idiopathic scoliosis in comparison with the normal population. The aim of this study was to assess the prevalence of low bone mass among adolescent girls with idiopathic scoliosis.Methods: In this cross-sectional study performed in shafa Hospital in Tehran, Iran during 2011-2012, we recruited fifty-seven 12- to-20-year old girls with idiopathic scoliosis and compared them with 100 age-matched healthy girls. The patients had no other diseases including neuromuscular disorders, congenital vertebral anomalies or a history of spinal surgery. Bone mineral densities (BMD of the hip and spine were evaluated and compared in all 157 participants using dual X-ray absorptiometry (DXA. Standard BMD (sBMD was also calculated at the lumbar spine. Results: Analysis of the data revealed that hip BMD was significantly (P=0.004 lower in patients with idiopathic scoliosis versus the controls. Moreover, BMD and sBMD of the Spine were also significantly lower in the patients (respectively, P=0.030 and P=0.030. Curve location had no effect on the values of hip BMD, spine BMD or spine sBMD (respectively, P=0.061 and P=0.274 and P=0.208.Finally, with more severe curves a lower bone mass was detected for sBMD and spine BMD (respectively, P=0.017 and P=0.016, but it was not significant for hip BMD (P=0.069.Conclusion: Adolescent girls with idiopathic scoliosis had lower bone mass compared with their healthy peers. The lower bone mass was correlated with the severity of the curve but not its location.

Full Text Available Plastic bronchitis is a rare disorder characterized by formation of large, branching bronchial casts, which are often expectorated. We present an interesting case of a 35-year-old woman who presented for evaluation of a chronic cough productive of voluminous secretions. Clinical and radiological examination confirmed a total left lung atelectasis without any pathological mediastinal node. Flexible bronchoscopy demonstrated tenacious, thick, and sticky whitish secretions blocking the left stem bronchus. This material was extracted, and inspection demonstrated a bronchial cast, whose pathological analysis revealed necrotic epithelial cells, some eosinophils, and Charcot-Leyden crystals. Two days after bronchoscopy, the patient rejected more bronchial casts, and dyspnea improved. Control of chest x-ray revealed complete left lung aeration and the diagnosis of idiopathic plastic bronchitis was obtained. This article shows the interest in clinical practice to evoke the diagnosis of plastic bronchitis in front of a productive chronic cough. Our case illustrates a rare clinical presentation represented by an atelectasis of an entire lung.

Core stabilization training is used to improve postural balance in musculoskeletal problems. The purpose of this study was to investigate the effectiveness of stabilization training in adolescent idiopathic scoliosis. A randomized controlled trial, pretest-posttest design. In total, 25 subjects with adolescent idiopathic scoliosis were randomly divided into two groups: stabilization group ( n = 12) and control group ( n = 13). The stabilization group received core stabilization in addition to traditional rehabilitation, and the control group received traditional rehabilitation for 10 weeks. Assessment included Cobb's angle on radiograph, apical vertebral rotation in Adam's test, trunk asymmetry (Posterior Trunk Symmetry Index), cosmetic trunk deformity (Trunk Appearance Perception Scale), and quality of life (Scoliosis Research Society-22 questionnaire). Inter-group comparisons showed significantly greater improvements in the mean change in lumbar apical vertebral rotation degree and the pain domain of Scoliosis Research Society-22 in the stabilization group than those in the control group ( p adolescent idiopathic scoliosis. Clinical relevance Stabilization exercises are more effective in reducing rotation deformity and pain than traditional exercises in the conservative rehabilitation of adolescent idiopathic scoliosis. These improvements suggest that stabilization training should be added to rehabilitation programs in adolescent idiopathic scoliosis.

The compound immunodeficiencies in nonobese diabetic (NOD) inbred mice homozygous for the Prkdc(scid) and Il2rg(null) alleles (NSG mice) permit engraftment of a wide-range of primary human cells, enabling sophisticated modeling of human disease. In studies designed to define neoplastic stem cells of primary myelofibrosis (PMF), a myeloproliferative neoplasm characterized by profound disruption of the hematopoietic microenvironment, we observed a high frequency of acute myeloid leukemia (AML) in NSG mice. AML was of mouse origin, confined to PMF-xenografted mice, and contained multiple clonal integrations of ecotropic murine leukemia virus (E-MuLV). Significantly, MuLV replication was not only observed in diseased mice, but also in nontreated NSG controls. Furthermore, in addition to the single ecotropic endogenous retrovirus (eERV) located on chromosome 11 (Emv30) in the NOD genome, multiple de novo germ-line eERV integrations were observed in mice from each of four independent NSG mouse colonies. Analysis confirmed that E-MuLV originated from the Emv30 provirus and that recombination events were not necessary for virus replication or AML induction. Pathogenicity is thus likely attributable to PMF-mediated paracrine stimulation of mouse myeloid cells, which serve as targets for retroviral infection and transformation, as evidenced by integration into the Evi1 locus, a hotspot for retroviral-induced myeloid leukemia. This study thus corroborates a role of paracrine stimulation in PMF disease progression, underlines the importance of target cell type and numbers in MuLV-induced disease, and mandates awareness of replicating MuLV in NOD immunodeficient mice, which can significantly influence experimental results and their interpretation.

To investigate whether idiopathic Horner's syndrome (HS) in Golden Retrievers is an exclusively preganglionic disorder based on denervation hypersensitivity pharmacological testing with phenylephrine. Medical records of dogs presented with HS between 2000 and 2012. Dogs presented with additional ocular or systemic signs were excluded. Clinical data examined included age, sex, duration of clinical signs, ancillary diagnostic test results, and time to mydriasis on topical ocular application of 1% phenylephrine. Lesions were diagnosed as postganglionic (mydriasis within 20 min) or preganglionic (mydriasis between 20 and 45 min). Medical records of 21 dogs of nine different breeds were included. An etiopathogenesis for Horner's syndrome was determined in five dogs, none of which were Golden Retrievers. All diagnoses correlated with pharmacological lesion localization. Ten Golden Retrievers were included (eight male and two female) with a mean age of 8.5 years (range: 4-13). Lesion localization was diagnosed as postganglionic in eight (mean: 10 min [range: 6-18]) and preganglionic in two Golden Retrievers (20 and 24 min). All cases were unilateral and had completely resolved within 15 weeks (range: 11-20). Recurrence was not reported in any of the patients. Idiopathic postganglionic HS was diagnosed in eight of 10 Golden Retrievers contradicting previous reports of a purely preganglionic localization. Etiopathogenesis of canine idiopathic HS remains to be determined; nevertheless, a vascular etiology cannot be excluded. Future studies using magnetic resonance angiography may aid in clarifying the pathogenesis. © 2013 American College of Veterinary Ophthalmologists.

MPLW515L/K and JAK2V617F can co-exist in myelofibrosis with myeloid metaplasia (MMM). The chronology of clonal emergence was studied in three such cases using serially stored bone marrow. At diagnosis, a major MPL515 mutant clone was accompanied by a minor JAK2V617F clone in all three instances. At 25 time points over a period of 4-8 years, allele burden fluctuated but remained high for MPLW515L/K and low for JAK2V617F. We conclude that MPLW515L/K and JAK2V617F are both early events in MMM and allele burden, rather than the mere presence of these mutations, might be relevant to phenotypic variation in myeloproliferative disorders.

Therapeutic Options in Idiopathic Burning Mouth Syndrome: Literature Review

Miziara, Ivan; Chagury, Azis; Vargas, Camila; Freitas, Ludmila; Mahmoud, Ali

2014-01-01

Introduction Burning mouth syndrome (BMS) is characterized by a burning sensation in the tongue, palate, lips, or gums of no well-defined etiology. The diagnosis and treatment for primary BMS are controversial. No specific laboratory tests or diagnostic criteria are well established, and the diagnosis is made by excluding all other possible disorders. Objective To review the literature on the main treatment options in idiopathic BMS and compare the best results of the main studies in 15 years. Data Synthesis We conducted a literature review on PubMed/MEDLINE, SciELO, and Cochrane-BIREME of work in the past 15 years, and only selected studies comparing different therapeutic options in idiopathic BMS, with preference for randomized and double-blind controlled studies. Final Comments Topical clonazepam showed good short-term results for the relief of pain, although this was not presented as a definitive cure. Similarly, α-lipoic acid showed good results, but there are few randomized controlled studies that showed the long-term results and complete remission of symptoms. On the other hand, cognitive therapy is reported as a good and lasting therapeutic option with the advantage of not having side effects, and it can be combined with pharmacologic therapy.

Anterior Hypopituitarism is Rare and Autoimmune Disease is Common in Adults with Idiopathic Central Diabetes Insipidus.

LENUS (Irish Health Repository)

2012-02-01

Objective: Central diabetes insipidus is a rare clinical condition with a heterogenous aetiology. Up to 40% of cases are classified as idiopathic, though many of these are thought to have an autoimmune basis. Published data has suggested that anterior hypopituitarism is common in childhood onset idiopathic diabetes insipidus. We aimed to assess the incidence of anterior hypopituitarism in a cohort of adult patients with idiopathic diabetes insipidus. Design and Patients: We performed a retrospective review of the databases of two pituitary investigation units. This identified 39 patients with idiopathic diabetes insipidus. All had undergone MRI scanning and dynamic pituitary testing (either insulin tolerance testing or GHRH\\/arginine and short synacthen testing) to assess anterior pituitary function. Results: One patient had partial growth hormone deficiency; no other anterior pituitary hormonal deficits were found. 33% had at least one autoimmune disease in addition to central diabetes insipidus. Conclusions: Our data suggest that anterior hypopituitarism is rare in adult idiopathic diabetes insipidus. Routine screening of these patients for anterior hypopituitarism may not therefore be indicated. The significant prevalence of autoimmune disease in this cohort supports the hypothesis that idiopathic diabetes insipidus may have an autoimmune aetiology.

Hepatic hematomas in newborn infants are not frequently detected clinically, but are often found at perinatal autopsies. These hematomas of the liver are usually subcapsular in location. A variety of etiologies for such hematomas has been implicated, such as trauma, sepsis, and coagulopathies. We present a neonate who presented with jaundice and abdominal distention. Initial imaging studies revealed a large intraparenchymal lesion of the liver, which was at first thought to be suspicious for neoplasm; however, MRI showed the lesion to be hemorrhagic and follow-up sonographic studies showed total resolution of this lesion, compatible with hematoma. The intraparenchymal location and the idiopathic nature of this lesion distinguish this case from others previously reported. (orig.)

The objective of this perspective is to present a separate disease description of "idiopathic canalicular inflammatory disease" and outline the diagnostic criteria and early experiences with its investigations and management. Retrospective case series of 44 canaliculi of 22 eyes of 11 patients presenting at a tertiary care Dacryology service over a period of 2 years with typical clinical patterns of inflammatory canaliculitis and its outcomes were studied. All the patients underwent microbiological work-up with culture and sensitivity, dacryoendoscopy imaging, serial Fourier domain ocular coherence tomography, and collagen vascular profiles. Stages in the evolution of the disease were studied. All patients were treated initially with topical steroids followed by punctal dilatation and placement of mini-monoka stents. Five patients in addition had a small biopsy from the inflamed portion of the vertical canaliculus. Stents were extubated at 6 weeks. Forty-four canaliculi were diagnosed to have idiopathic canalicular inflammatory disease during the study period. There was a female preponderance (81.8%, 9/11) and the mean age at presentation was 57 years. All patients presented with unilateral epiphora without any discharge, pain, or swelling. Collagen vascular profiles and screening for autoimmune diseases were negative. Clinical picture ranged from stages 1 to 5, consisting of edema, progressive centripetal vascularization, pouting of vascularized mucosa, membrane formation, and progressive scarring. The presentation begins in 1 eye and usually involves the other eye at a mean of 6 months. Ocular coherence tomography and dacryoendoscopy were of adjunctive value in the diagnosis. Histopathological examination was suggestive of a chronic inflammation. All patients had relentless progression to end-stage disease, although delayed significantly by steroids and monoka intubation. Idiopathic canalicular inflammatory disease has a distinct and typical clinical behavior and

No ideal therapeutic method currently exists for refractory idiopathic supraorbital neuralgia patients who do not respond to conservative therapy, including medications and nerve blocks. Pulsed radiofrequency is a neuromodulation technique that does not produce sequelae of nerve damage after treatment. However, the efficacy of percutaneous pulsed radiofrequency for the treatment of refractory idiopathic supraorbital neuralgia is still not clear. The purpose of our study was to evaluate the efficacy and safety of pulsed radiofrequency treatment of the supraorbital nerve for refractory supraorbital neuralgia patients. We prospectively investigated the long-term effects of ultrasound-guided percutaneous pulsed radiofrequency in the treatment of 22 refractory idiopathic supraorbital neuralgia patients. A reduction in the verbal pain numeric rating scale score of more than 50% was used as the standard of effectiveness. The effectiveness rates at different time points within 2 years were calculated. After a single pulsed radiofrequency treatment, the effectiveness rate at 1 and 3 months was 77%, and the rates at 6 months, 1 year, and 2 years were 73%, 64%, and 50%, respectively. Except for a small portion of patients (23%) who experienced mild upper eyelid ecchymosis that gradually disappeared after approximately 2 weeks, no obvious complications were observed. In conclusion, the results of our study demonstrate that for patients with refractory idiopathic supraorbital neuralgia, percutaneous pulsed radiofrequency may be an effective and safe treatment choice. © 2018 World Institute of Pain.

Familial Idiopathic Cranial Neuropathy in a Chinese Family.

Science.gov (United States)

Zhang, Li; Liang, Jianfeng; Yu, Yanbing

Cranial neuropathy is usually idiopathic and familial cases are uncommon. We describe a family with 5 members with cranial neuropathy over 3 generations. All affected patients were women, indicating an X-linked dominant or an autosomal dominant mode of inheritance. Our cases and a review of the literature suggest that familial idiopathic cranial neuropathy is a rare condition which may be related to autosomal dominant vascular disorders (e.g. vascular tortuosity, sclerosis, elongation or extension), small posterior cranial fossas, anatomical variations of the posterior circulation, hypersensitivity of cranial nerves and other abnormalities. Moreover, microvascular decompression is the treatment of choice because vascular compression is the main factor in the pathogenesis. To the best of our knowledge, this is the first report of familial cranial neuropathy in China.

Idiopathic basal ganglia calcification is characterized by mineral deposits in the brain, an autosomal dominant pattern of inheritance in most cases and genetic heterogeneity. The first causal genes, SLC20A2 and PDGFRB, have recently been reported. Diagnosing idiopathic basal ganglia calcification necessitates the exclusion of other causes, including calcification related to normal ageing, for which no normative data exist. Our objectives were to diagnose accurately and then describe the clinical and radiological characteristics of idiopathic basal ganglia calcification. First, calcifications were evaluated using a visual rating scale on the computerized tomography scans of 600 consecutively hospitalized unselected controls. We determined an age-specific threshold in these control computerized tomography scans as the value of the 99th percentile of the total calcification score within three age categories: 60 years. To study the phenotype of the disease, patients with basal ganglia calcification were recruited from several medical centres. Calcifications that rated below the age-specific threshold using the same scale were excluded, as were patients with differential diagnoses of idiopathic basal ganglia calcification, after an extensive aetiological assessment. Sanger sequencing of SLC20A2 and PDGFRB was performed. In total, 72 patients were diagnosed with idiopathic basal ganglia calcification, 25 of whom bore a mutation in either SLC20A2 (two families, four sporadic cases) or PDGFRB (one family, two sporadic cases). Five mutations were novel. Seventy-one per cent of the patients with idiopathic basal ganglia calcification were symptomatic (mean age of clinical onset: 39 ± 20 years; mean age at last evaluation: 55 ± 19 years). Among them, the most frequent signs were: cognitive impairment (58.8%), psychiatric symptoms (56.9%) and movement disorders (54.9%). Few clinical differences appeared between SLC20A2 and PDGFRB mutation carriers. Radiological analysis

Idiopathic fibrosing pancreatitis is a chronic process of unknown etiology characterized by extensive infiltration of the pancreatic parenchyma by fibrous tissue. This disease process is uncommon in the pediatric patient and is consequently rarely considered in the differential diagnosis of abdominal pain and jaundice in the child. The sonographic demonstration of a dilated biliary tree and common bile duct compressed by an enlarged pancreas may be the first suggestion of this entity. Two patients with idiopathic fibrosing pancreatitis and obstructive jaundice are reported with a review of the clinical, radiographic, and pathologic findings. (orig.)

Juvenile idiopathic arthritis (JIA) is the most common arthropathy of childhood and adolescence. This term encompasses a group of chronic systemic inflammatory diseases of the connective tissue which cause arthritis in patients under 16 years of age lasting at least 6 weeks. The authors presented the characteristic features of physiotherapy based on functional examination results on the basis of two cases of girls with pauciarticular JIA treated according to an established pharmacological regimen. Physiotherapy should be introduced at an early stage of the disease. Kinesiotherapy preceded by history-taking and a functional examination of the patient, has to focus on both primary and secondary joint lesions.

Clinical characteristics did not influence those results. Conclusion This study found a greater prevalence of problems wih attention in pediatric patients with idiopathic epilepsy, but not a distinct profile between those with or without ADHD.

Idiopathic Syringomyelia in a Military Helicopter Pilot.

Schiemer, Anthony

2017-10-01

A syrinx is a fluid-filled cavity within the spinal cord. They can lead to a variety of symptoms, including limb weakness and back pain. Incidental finding of syringomyelia provides a challenge for clinicians due to the wide variety of possible symptoms. In military aviation, neurological findings in pilots can result in extensive investigation that can lead to potentially invasive management. Conversely, the potential for chronic progression of a spinal syrinx and subsequent neurological deterioration makes early identification critical. Ultimately, the discovery of a lesion may have implications for flying status and operational capability. A 25-yr-old man working as a navy Seahawk helicopter pilot presented with episodes of right arm paraesthesia and pain between the scapulae. On at least one occasion, these symptoms woke him at night. Upon magnetic resonance imaging, dilatation of the central canal in a syrinx-like pattern in the lower cervical region was noted. Neurology review suggested the finding was persistent and unlikely to be responsible for his symptoms. No surgical input was recommended. His symptoms were attributed to mild cervical spondylosis, which resolved with ongoing physiotherapy, and he was returned to flying status. This case highlights several issues involved with the incidental finding of a syringomyelia. Surgical intervention has been known to worsen symptoms. Conversely, studies have identified minimal radiological progression in cases of idiopathic syringomyelia, with fewer individuals displaying neurological deterioration. For aircrew, potentially unnecessary neurosurgical intervention poses risks to a flying career and overall operational capability.Schiemer A. Idiopathic syringomyelia in a military helicopter pilot.

We studied the impact of driver mutations of JAK2, CALR, (calreticulin gene) or MPL on clinical course, leukemic transformation, and survival of patients with primary myelofibrosis (PMF). Of the 617 subjects studied, 399 (64.7%) carried JAK2 (V617F), 140 (22.7%) had a CALR exon 9 indel, 25 (4.0%) carried an MPL (W515) mutation, and 53 (8.6%) had nonmutated JAK2, CALR, and MPL (so-called triple-negative PMF). Patients with CALR mutation had a lower risk of developing anemia, thrombocytopenia, and marked leukocytosis compared with other subtypes. They also had a lower risk of thrombosis compared with patients carrying JAK2 (V617F). At the opposite, triple-negative patients had higher incidence of leukemic transformation compared with either CALR-mutant or JAK2-mutant patients. Median overall survival was 17.7 years in CALR-mutant, 9.2 years in JAK2-mutant, 9.1 years in MPL-mutant, and 3.2 years in triple-negative patients. In multivariate analysis corrected for age, CALR-mutant patients had better overall survival than either JAK2-mutant or triple-negative patients. The impact of genetic lesions on survival was independent of current prognostic scoring systems. These observations indicate that driver mutations define distinct disease entities within PMF. Accounting for them is not only relevant to clinical decision-making, but should also be considered in designing clinical trials. © 2014 by The American Society of Hematology.

Despite common use of proprioceptive retraining interventions in people with chronic, idiopathic neck pain, evidence that proprioceptive dysfunction exists in this population is lacking. Determining whether proprioceptive dysfunction exists in people with chronic neck pain has clear implications for treatment prescription. The aim of this study was to synthesize and critically appraise all evidence evaluating proprioceptive dysfunction in people with chronic, idiopathic neck pain by completing a systematic review and meta-analysis. MEDLINE, CINAHL, PubMed, Allied and Complementary Medicine, EMBASE, Academic Search Premier, Scopus, Physiotherapy Evidence Database (PEDro), and Cochrane Collaboration databases were searched. All published studies that compared neck proprioception (joint position sense) between a chronic, idiopathic neck pain sample and asymptomatic controls were included. Two independent reviewers extracted relevant population and proprioception data and assessed methodological quality using a modified Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement. Thirteen studies were included in the present review. Meta-analysis on 10 studies demonstrated that people with chronic neck pain perform significantly worse on head-to-neutral repositioning tests, with a moderate standardized mean difference of 0.44 (95% confidence interval=0.25, 0.63). Two studies evaluated head repositioning using trunk movement (no active head movement thus hypothesized to remove vestibular input) and showed conflicting results. Three studies evaluated complex or postural repositioning tests; postural repositioning was no different between groups, and complex movement tests were impaired only in participants with chronic neck pain if error was continuously evaluated throughout the movement. A paucity of studies evaluating complex or postural repositioning tests does not permit any solid conclusions about them. People with chronic, idiopathic

When compared to boys, girls have smaller vertebral cross-sectional area, which conveys a greater spinal flexibility, and a higher prevalence of adolescent idiopathic scoliosis. To test the hypothesis that small vertebral cross-sectional area and tall intervertebral disc height are structural characteristics of patients with adolescent idiopathic scoliosis. Using multiplanar imaging techniques, measures of vertebral cross-sectional area, vertebral height and intervertebral disc height in the lumbar spine were obtained in 35 pairs of girls and 11 pairs of boys with and without adolescent idiopathic scoliosis of the thoracic spine matched for age, height and weight. Compared to adolescents without spinal deformity, girls and boys with adolescent idiopathic scoliosis had, on average, 9.8% (6.68 ± 0.81 vs. 7.40 ± 0.99 cm{sup 2}; P = 0.0007) and 13.9% (8.22 ± 0.84 vs. 9.55 ± 1.61 cm{sup 2}; P = 0.009) smaller vertebral cross-sectional dimensions, respectively. Additionally, patients with adolescent idiopathic scoliosis had significantly greater values for intervertebral disc heights (9.06 ± 0.85 vs. 7.31 ± 0.62 mm and 9.09 ± 0.87 vs. 7.61 ± 1.00 mm for girls and boys respectively; both P ≤ 0.011). Multiple regression analysis indicated that the presence of scoliosis was negatively associated with vertebral cross-sectional area and positively with intervertebral disc height, independent of sex, age and body mass index. We provide new evidence that girls and boys with adolescent idiopathic scoliosis have significantly smaller vertebral cross-sectional area and taller intervertebral disc heights - two major structural determinants that influence trunk flexibility. With appropriate validation, these findings may have implications for the identification of children at the highest risk for developing scoliosis. (orig.)

Full Text Available Background: The connection between vaccination and autoimmune diseases (and rheumatic pathology in particular is still a subject of discussions. When discussing the possibility of vaccinating rheumatic patients we should take into account the ultra high dangers that infectious diseases pose for such patients, including those that can be prevented by vaccination. We should also take into account the experience of using various vaccine types in rheumatic patients, which illustrates of their high safety profile.Objective: Our aim was to study the immunization schedule in children with juvenile idiopathic arthritis.Methods: The evaluation of vaccine history and other anamnestic data in juvenile idiopathic arthritis patients was based on individual medical records (individual child’s card/preventive vaccination certificate, as well as questionnaires filled by mothers.Results: It has been determined that a significant proportion of children with vaccination schedule deviations are juvenile idiopathic arthritis patients. Almost one in four children with a confirmed rheumatic diagnosis has not been immunized against the major vaccine-preventable diseases. In one non-vaccinated group, there was a case of juvenile arthritis onset after recovering from measles. A small number of patient mothers connects the manifestation of rheumatic diseases with vaccination.Conclusion: Violations of vaccination status in JIA patients require corrections according to the results of clinical studies and the recommendations of international experts.

2008-10-01

The lack of evidence of conservative treatment has led to an interest in exploring myofascial release (MFR) as an effective means of controlling spinal curvature progression in adolescents with idiopathic scoliosis. The purpose of this case study is to measure the effects of MFR as a manual therapy technique in the treatment of idiopathic scoliosis. One 18-year-old female subject underwent 6 weeks of MFR treatment consisting of two sessions each week for 60min. Pain, pulmonary function, and quality of life were measured. Six goniometric measurements were taken encompassing trunk flexion, extension, and rotation. The subject improved with pain levels, trunk rotation, posture, quality of life, and pulmonary function. The results suggest further investigation is needed using MFR, as an effective manual therapy treatment for idiopathic scoliosis.

Full Text Available Retroperitoneal fibrosis (RPF is a rare disease characterized by the presence of fibroinflammatory tissue around the abdominal aorta and ureteral entrapment in most cases. Idiopathic RPF is frequently reported in association with autoimmune diseases; however, there have been few reports of idiopathic RPF associated with Hashimoto's thyroiditis. Here, we report a case of idiopathic RPF with Hashimoto's thyroiditis in a patient with a single functioning kidney, which was successfully treated by corticosteroid therapy and transient intraureteral stent insertion with a double-J catheter.

Idiopathic granulomatous mastitis: a case report of breast abscess.

Olsen, Molly L; Dilaveri, Christina A

2011-08-04

Idiopathic granulomatous mastitis (IGM) is an uncommon breast disease often mistaken for breast infection or abscess. We present a case of IGM diagnosed after prolonged ineffective treatment of presumed infectious mastitis with abscess. Once the diagnosis was made with biopsy and further evaluation to exclude other causes of granulomatous disease, sinus tract debridement and closure by secondary intent resulted in resolution of symptoms in our patient. Many cases of IGM require immunosuppression with steroids, methotrexate or extensive surgery. To prevent morbidity, IGM should be considered in the differential diagnosis when presumed infectious mastitis with breast abscess does not respond to usual treatment.

Idiopathic mast cell activation syndrome can be a rare cause for chronic abdominal pain in children. It remains a diagnosis by exclusion that can be particularly challenging due to the vast variety of possible clinical manifestations. We present a 13-year-old boy who suffered from a multitude of unspecific complaints over a long period of time. In this case, an assessment of mast cell-derived metabolites and immunohistochemical analysis of bioptic specimen was worthwhile. After ruling out, primary (oncologic) and secondary causes for mast cell activation, pharmacologic treatment adapted to the patient's salicylate intolerance resulted in a major relief of symptoms.

To evaluate the frequency of non-autoimmune subclinical and overt hypothyroidism in children with idiopathic steroid-resistant nephrotic syndrome (SRNS). This cross-sectional study recruited 30 children (age 1-18 y) with idiopathic SRNS; and 30 healthy controls. Serum T3, T4 and TSH were performed in cases as well as controls. Anti-thyroid peroxidase and anti-thyroglobulin antibody tests were performed in all cases. Non-autoimmune subclinical or overt hypothyroidism was detected in 10 out of 30 children with idiopathic SRNS; 2 had overt hypothyroidism, while 8 patients had subclinical hypothyroidism. Children with SRNS had a mean (SD) TSH value 4.55 (4.64) mIU/L that was higher as compared to controls (1.88 (1.04) mIU/L) (Phypothyroidism (2 cases) and grade III subclinical hypothyroidism (1 case) were subsequently started on levothyroxine therapy. The prevalence of subclinical and overt hypothyroidism seems to be high in idiopathic SRNS, with almost one-third of children having overt or subclinical non-autoimmune hypothyroidism.

Full Text Available The detection of any atypical extraoral or intraoral features warrants a thorough investigation, even if the patient is asymptomatic or unaware of these. At times, dental findings help in the diagnosis of an underlying systemic problem. These findings may or may not be associated with any syndrome. Thus, thorough examination and exhaustive investigations should be carried out for every atypical finding to ensure optimal oral and general health for the patient. Case Description: This is a case report of seventeen year old male who presented with peculiar/atypical dentition which ′told the tale′ and led to the diagnosis of underlying endocrinological problem about which the parents were totally unaware. The patient was short with central obesity and microcephaly. Intraorally, there was presence of thirty six microdonts. Consultation with pediatrician and endocrinologist, and thorough investigations confirmed the condition to be of ′Idiopathic Hypergonadotropic Hypogonadism′. The patient underwent not only oral rehabilitation, but also timely consultation and treatment from a pediatrician and an endocrinologist.

Effect of acid suppression therapy on gastroesophageal reflux and cough in idiopathic pulmonary fibrosis: an intervention study.

2014-01-01

Chronic cough affects more than 70 percent of patients with Idiopathic Pulmonary Fibrosis and causes significant morbidity. Gastroesophageal reflux is the cause of some cases of chronic cough; and also has a postulated role in the aetiology of Idiopathic Pulmonary Fibrosis. A high prevalence of acid; and more recently non-acid, reflux has been observed in Idiopathic Pulmonary Fibrosis cohorts. Therefore, gastroesophageal reflux may be implicated in the pathogenesis of cough in Idiopathic Pulmonary Fibrosis. Eighteen subjects with Idiopathic Pulmonary Fibrosis underwent 24-hour oesophageal impedance and cough count monitoring after the careful exclusion of causes of chronic cough other than gastroesophageal reflux. All 18 were then treated with high dose acid suppression therapies. Fourteen subjects underwent repeat 24-hour oesophageal impedance and cough count monitoring after eight weeks. Total reflux and acid reflux frequencies were within the normal range in the majority of this cohort. The frequencies of non-acid and proximal reflux events were above the normal range. Following high dose acid suppression therapy there was a significant decrease in the number of acid reflux events (p = 0.02), but an increase in the number of non-acid reflux events (p = 0.01). There was no change in cough frequency (p = 0.70). This study confirms that non-acid reflux is prevalent; and that proximal oesophageal reflux occurs in the majority, of subjects with Idiopathic Pulmonary Fibrosis. It is the first study to investigate the effect of acid suppression therapy on gastroesophageal reflux and cough in patients with Idiopathic Pulmonary Fibrosis. The observation that cough frequency does not improve despite verifiable reductions in oesophageal acid exposure challenges the role of acid reflux in Idiopathic Pulmonary Fibrosis associated cough. The finding that non-acid reflux is increased following the use of acid suppression therapies cautions against the widespread use

Pathogenetic Role of JAK2 V617F Mutation in Chronic Myeloproliferative Disorders

Directory of Open Access Journals (Sweden)

Hui-Chi Hsu

2007-03-01

Full Text Available The molecular pathogenesis of chronic myeloproliferative disorders (MPDs is poorly understood. The hematopoietic progenitor cells of patients with polycythemia vera (PV or essential thrombocythemia (ET are characterized by hypersensitiv-ity to hematopoietic growth factors and formation of endogenous erythroid colonies. Recently, 4 groups reported almost simultaneously Janus kinase 2 (JAK2 V617F mutation in more than 80% of PV patients, 30% of patients with ET and in about 50% of patients with idiopathic myelofibrosis. The identification of the JAK2 mutation represents a major advance in the understanding of the molecular pathogenesis of MPDs that will likely permit a new classification and the development of novel therapeutic strategies for these diseases.

Tie2 Expressing Monocytes in the Spleen of Patients with Primary Myelofibrosis.

Directory of Open Access Journals (Sweden)

Rita Campanelli

Full Text Available Primary myelofibrosis (PMF is a Philadelphia-negative (Ph- myeloproliferative disorder, showing abnormal CD34+ progenitor cell trafficking, splenomegaly, marrow fibrosis leading to extensive extramedullary haematopoiesis, and abnormal neoangiogenesis in either the bone marrow or the spleen. Monocytes expressing the angiopoietin-2 receptor (Tie2 have been shown to support abnormal angiogenic processes in solid tumors through a paracrine action that takes place in proximity to the vessels. In this study we investigated the frequency of Tie2 expressing monocytes in the spleen tissue samples of patients with PMF, and healthy subjects (CTRLs, and evaluated their possible role in favouring spleen angiogenesis. We show by confocal microscopy that in the spleen tissue of patients with PMF, but not of CTRLs, the most of the CD14+ cells are Tie2+ and are close to vessels; by flow cytometry, we found that Tie2 expressing monocytes were Tie2+CD14lowCD16brightCDL62-CCR2- (TEMs and their frequency was higher (p = 0.008 in spleen tissue-derived mononuclear cells (MNCs of patients with PMF than in spleen tissue-derived MNCs from CTRLs undergoing splenectomy for abdominal trauma. By in vitro angiogenesis assay we evidenced that conditioned medium of immunomagnetically selected spleen tissue derived CD14+ cells of patients with PMF induced a denser tube like net than that of CTRLs; in addition, CD14+Tie2+ cells sorted from spleen tissue derived single cell suspension of patients with PMF show a higher expression of genes involved in angiogenesis than that found in CTRLs. Our results document the enrichment of Tie2+ monocytes expressing angiogenic genes in the spleen of patients with PMF, suggesting a role for these cells in starting/maintaining the pathological angiogenesis in this organ.

Successful treatment of idiopathic pulmonary capillaritis with intravenous cyclophosphamide.

LENUS (Irish Health Repository)

Flanagan, Frances

2013-03-01

Idiopathic pulmonary hemosiderosis (IPH), a subtype of diffuse alveolar hemorrhage is a rare condition, first described by Virchow in 1864. Historically, it manifests in children in the first decade of life with the combination of hemoptysis, iron deficiency anemia, and alveolar infiltrates on chest radiograph. More recently, diffuse alveolar hemorrhage has been classified by the absence or presence of pulmonary capillaritis (PC), the latter carrying a potential for a poorer outcome. While systemic corticosteroids remain the first line treatment option, other immune modulators have been trailed including hydroxychloroquine, azathioprine, 6-mercaptopurine, and cyclophosphamide with varying results. Our case demonstrates for the first time, the successful use of intravenous cyclophosphamide in the management of chronic idiopathic PC.

Full Text Available Arteriovenous malformations (AVM of the inferior mesenteric artery are rare. They may be primary (congenital or idiopathic or secondary (acquired after trauma or of iatrogenic origin. Of the abdominal AVM, the inferior mesenteric trunk is the least commonly involved. Most reported cases are of iatrogenic origin, resulting from colon surgery. Only 17 cases have been described and published in the literature. The objective of this work is to make known a case treated in our center. We present a case of 73-year old male, who came to the emergency service with symptoms of abdominal distension, pain lasting 48 hours along with months of diarrhoea. CT scan and an abdominal CT angiography showed a massive left-sided congestive colitis due to idiopathic inferior mesenteric arteriovenous malformation. In our case, the decision was to carry out the treatment in two stages. Embolisation was performed in the first stage in order to decrease the blood flow and the risk of intraoperative bleeding, followed by resective surgery of the affected colon.

The objective of this study was to detect testosterone(T), free testosterone (FT) and sex hormone-binding globulin(SHBG) in serum and semen of patients with idiopathic oligospermia, and further analyze the relationship between T, FT, SHBG and idiopathic oligospermia. Blood and semen samples were collected from males of a normal control group and an idiopathic oligospermia group at 8:00-10:00 am. The sperm density in semen was detected by routine semen analysis, while T, FT, SHBG in serum and semen were detected by RIA. There were no significant differences in serum concentrations of T, FT, SHBG between normal control group [(30.03±13.07)nmol/L,(97.50±46.96)pmol/L, (40.37±16.73)nmol/L, respectively] and idiopathic oligspermia group [(28.11±11.54) nmol/L, (94.88±42.04) pmol/L, (41.61± 18.86)noml/LJ(all P>0. 05). There were significant differences in semsn concentrations of FT and SHBG between normal control group[(2.01±0.32) pmol/L, (0.17±0.21)nmol/L] and idiopathic oligspermia group [ (0.52±0.44) pmol/L, (0.22±0.15) nmol/LJ (P 0.05). Therefore, measurement of semsn FT, SHBG concentration could early reflect the function of tesis, which is useful for early diagnosis and treatment of idiopathic oligospermia. (authors)

To describe the clinical phenotype of idiopathic rapid eye movement (REM) sleep behavior disorder (IRBD) at presentation in a sleep center. Clinical history review of 203 consecutive patients with IRBD identified between 1990 and 2014. IRBD was diagnosed by clinical history plus video-polysomnographic demonstration of REM sleep with increased electromyographic activity linked to abnormal behaviors. Patients were 80% men with median age at IRBD diagnosis of 68 y (range, 50-85 y). In addition to the already known clinical picture of IRBD, other important features were apparent: 44% of the patients were not aware of their dream-enactment behaviors and 70% reported good sleep quality. In most of these cases bed partners were essential to convince patients to seek medical help. In 11% IRBD was elicited only after specific questioning when patients consulted for other reasons. Seven percent did not recall unpleasant dreams. Leaving the bed occurred occasionally in 24% of subjects in whom dementia with Lewy bodies often developed eventually. For the correct diagnosis of IRBD, video-polysomnography had to be repeated in 16% because of insufficient REM sleep or electromyographic artifacts from coexistent apneas. Some subjects with comorbid obstructive sleep apnea reported partial improvement of RBD symptoms following continuous positive airway pressure therapy. Lack of therapy with clonazepam resulted in an increased risk of sleep related injuries. Synucleinopathy was frequently diagnosed, even in patients with mild severity or uncommon IRBD presentations (e.g., patients who reported sleeping well, onset triggered by a life event, nocturnal ambulation) indicating that the development of a neurodegenerative disease is independent of the clinical presentation of IRBD. We report the largest IRBD cohort observed in a single center to date and highlight frequent features that were not reported or not sufficiently emphasized in previous publications. Physicians should be aware of

Full Text Available Systemic onset juvenile idiopathic arthritis (SOJIA can be associated with proteinuria due to various renal pathologies. We report two pediatric cases with SOJIA and nephrotic syndrome secondary to renal amyloidosis, a very rare complication in children. Once present, amyloidosis heralds a poor prognosis for the patient, though early detection may allow some improvement if the inflammatory arthritis is controlled.

Full Text Available OBJECTIVE: To correlate the incidence of hemorrhage and thrombosis to bleeding time (BT and platelet aggregation in 27 consecutive patients with myeloproliferative diseases (MPD. DESIGN: Retrospective study. SETTING: Public tertiary referral center. PATIENTS: Eighteen patients with chronic myelogenous leukemia (CML, 5 with polycytemia vera (PV, 2 with essential thrombocytemia (ET and 2 with idiopathic myelofibrosis (MF. Duke's BT and epinephrine-induced platelet aggregation were performed on the patients and on 10 healthy individuals. RESULTS: Eleven patients presented symptoms (41 %: 9 with hemorrhage (33% and 5 with thrombosis (19%.There were less symptomatic patients in the CML group (28% than in the other MPD (67%, without statistical significance (Fisher, p=0.06. Duke's BT was longer in symptomatic patients (Mann-Whitney, p<0.05. Platelet aggregation was abnormal in 7 patients (26% and 71% of them were symptomatic (Fisher, p = 0.07. CONCLUSIONS: The high incidence of bleeding and thrombosis in patients with MPD was related to prolonged BT, but not to platelet aggregation abnormalities.

The natural history of adolescent idiopathic scoliosis

Full Text Available There have been great advances in the conservative and surgical treatment for adolescent idiopathic scoliosis in the last few decades. The challenge for the physician is the decision for the optimal time to institute therapy for the individual child. This makes an understanding of the natural history and risk factors for curve progression of significant importance. Reported rates of curve progression vary from 1.6% for skeletally mature children with a small curve magnitude to 68% for skeletally immature children with larger curve magnitudes. Although the patient′s age at presentation, the Risser sign, the patient′s menarchal status and the magnitude of the curve have been described as risk factors for curve progression, there is evidence that the absolute curve magnitude at presentation may be most predictive of progression in the long term. A curve magnitude of 25º at presentation may be predictive of a greater risk of curve progression. Advances in research may unlock novel predictive factors, which are based on the underlying pathogenesis of this disorder.

Idiopathic Pulmonary Fibrosis—Clinical presentation, outcome and baseline prognostic factors in a Portuguese cohort

2013-01-01

Full Text Available Introduction: Idiopathic Pulmonary Fibrosis (IPF is the most common disease in the subgroup of idiopathic interstitial pneumonias. It is inevitably associated to a bad prognosis, although assuming a highly variable clinical course. Methods: Patients with IPF, observed at Interstitial Lung Diseases outpatient clinic of Centro Hospitalar de São João – Porto, Portugal, were identified and clinical, functional, radiological and bronchoalveolar lavage (BAL parameters were reviewed. Their clinical course and survival were analyzed in order to identify prognostic factors. Results: Eighty-one patients were included, with a mean age at diagnosis of 63.8 years old. At diagnosis, the main functional abnormalities were restrictive physiology, reduced lung diffusion and exercise capacity impairment. Clinical course was mainly slowly progressive (72.3%. Ten patients (13.2% had a rapid progression and 11 (14.5% patients had an acute exacerbation during the course of the disease. IPF's rapid progression was associated to a higher functional impairment at diagnosis, namely in what is related with Functional Vital Capacity (FVC and Total Lung Capacity (TLC. Median survival was 36 months. A significant difference in survival was observed among different types of clinical course – 41 months for slow progressors and 9 months for rapid progressors. Lower levels of FVC, TLC, six-minute walk test (6MWT distance and rest PaO2, and higher BAL neutrophil count were associated with poorer survival in univariate analysis. Conclusion: The analysis of this group of IPF patients confirms two clearly different phenotypes, slow and rapid progressors. Those phenotypes seem to have different presentations and a remarkably different natural history. These results could mean different physiopathologic pathways, which could implicate different therapeutic approaches.

Immunohistochemical detection of virus through its nuclear cytopathic effect in idiopathic interstitial pneumonia other than acute exacerbation

Directory of Open Access Journals (Sweden)

G.C. dos Santos

2013-11-01

Full Text Available Idiopathic interstitial pneumonias include complex diseases that have a strong interaction between genetic makeup and environmental factors. However, in many cases, no infectious agent can be demonstrated, and these clinical diseases rapidly progress to death. Theoretically, idiopathic interstitial pneumonias could be caused by the Epstein-Barr virus, cytomegalovirus, adenovirus, hepatitis C virus, respiratory syncytial virus, and herpesvirus, which may be present in such small amounts or such configuration that routine histopathological analysis or viral culture techniques cannot detect them. To test the hypothesis that immunohistochemistry provides more accurate results than the mere histological demonstration of viral inclusions, this method was applied to 37 open lung biopsies obtained from patients with idiopathic interstitial pneumonias. As a result, immunohistochemistry detected measles virus and cytomegalovirus in diffuse alveolar damage-related histological patterns of acute exacerbation of idiopathic pulmonary fibrosis and nonspecific interstitial pneumonia in 38 and 10% of the cases, respectively. Alveolar epithelium infection by cytomegalovirus was observed in 25% of organizing pneumonia patterns. These findings were coincident with nuclear cytopathic effects but without demonstration of cytomegalovirus inclusions. These data indicate that diffuse alveolar damage-related cytomegalovirus or measles virus infections enhance lung injury, and a direct involvement of these viruses in diffuse alveolar damage-related histological patterns is likely. Immunohistochemistry was more sensitive than the histological demonstration of cytomegalovirus or measles virus inclusions. We concluded that all patients with diffuse alveolar damage-related histological patterns should be investigated for cytomegalovirus and measles virus using sensitive immunohistochemistry in conjunction with routine procedures.

Physiotherapeutic Scoliosis-Specific Exercises (PSSE) and bracing have been found to be effective in the stabilization of curves in patients with Adolescent Idiopathic Scoliosis (AIS). Yet, the difference among the many PSSEs and braces has not been studied. The present review attempts to investigate the role of curve correction in the outcome of treatment for PSSEs and braces. A PubMed manual search has been conducted for studies on the role of correction in the effectiveness of PSSE and bracing. For the PSSEs, the key words used were "adolescent idiopathic scoliosis, correction, physiotherapy, physical therapy, exercise, and rehabilitation." For bracing, the key words used were "adolescent idiopathic scoliosis, correction and brace". Only papers that were published from 2001-2017 were included and reviewed, as there were very few relevant papers dating earlier than 2001. The search found no studies on the role of correction on the effectiveness of different PSSEs. The effectiveness of different PSSEs might or might not be related to the magnitude of curve correction during the exercises. However, many studies showed a relationship between the magnitude of in-brace correction and the outcome of the brace treatment. The role of correction on the effectiveness of PSSE has not been studied. In-brace correction, however, has been found to be associated with the outcome of brace treatment. An in-brace correction of 40-50% was associated with an increased rate of brace treatment success ( i.e . stabilization or improvement of curves). Thus, in the treatment of AIS, patients should be advised to use highly corrective braces, in conjunction with PSSE since exercises have been found to help stabilize the curves during weaning of the brace. Presently, no specific PSSE can be recommended. Braces of high in-brace correction should be used in conjunction with PSSEs in the treatment of AIS. No specific PSSE can be recommended as comparison studies of the effectiveness of

Idiopathic pulmonary fibrosis may be a disease of recurrent, tractional injury to the periphery of the aging lung: a unifying hypothesis regarding etiology and pathogenesis.

Leslie, Kevin O

2012-06-01

Idiopathic pulmonary fibrosis is a progressive, fatal lung disease occurring in older individuals. Despite 50 years of accrued data about the disease, little progress has been made in slowing functional loss or in decreasing patient mortality. To present a novel hypothesis on the etiology and pathogenesis of idiopathic pulmonary fibrosis. Published data are reviewed regarding the epidemiology, clinical presentation, natural history, radiologic findings, and pathologic findings in patients with idiopathic pulmonary fibrosis. Patients with idiopathic pulmonary fibrosis may be predisposed genetically to tractional injury to the peripheral lung. The result is recurrent damage to the epithelial-mesenchymal interface, preferentially at the outer edges of the basilar lung lobules where tractional stress is high during inspiration, compliance is relatively low, and there is a greater tendency for alveolar collapse at end-expiration. A distinctive "reticular network of injury" (the fibroblast focus) forms, attended by a prolonged phase of wound repair (tear and slow repair). Discrete areas of alveolar collapse are observed in scar at the periphery of the lung lobules. The cycle repeats over many years resulting in progressive fibrous remodeling and replacement of the alveoli in a lobule by bronchiolar cysts surrounded by scar (honeycomb lung). Abnormalities in surfactant function are proposed as a potential mechanism of initial lung damage. Age of onset may be a function of a required threshold of environmental exposures (eg, cigarette smoking) or other comorbid injury to the aging lung. Evidence supporting this hypothesis is presented and potential mechanisms are discussed. A potential role for contributing cofactors is presented.

2012-12-01

Full Text Available Abstract A seven-year old Australian Shepherd, suffering from idiopathic epilepsy under treatment with phenobarbitone and potassium bromide, was presented with generalised lower motor neuron signs. Electrophysiology and muscle-nerve biopsies revealed a neuromyopathy. The serum bromide concentration was increased more than two-fold above the upper reference value. Clinical signs disappeared after applying diuretics and reducing the potassium bromide dose rate. This is the first case report describing electrophysiological and histopathological findings associated with bromide induced lower motor neuron dysfunction in a dog.

Epithelial to mesenchymal transition has been suggested as a relevant contributor to pulmonary fibrosis, but how and where this complex process is triggered in idiopathic pulmonary fibrosis is not fully understood. Beta-tubulin-III (Tubβ3), ZEB1, and β-catenin are partially under the negative control of miR-200, a family of micro-RNAs playing a major role in epithelial to mesenchymal transition, that are reduced in experimental lung fibrosis and idiopathic pulmonary fibrosis. We wonder whether in situ expression of these proteins is increased in idiopathic pulmonary fibrosis, to better understand the significance of miR-200 feedback loop and epithelial to mesenchymal transition. We investigated the immunohistochemical and immunofluorescent expression and precise location of ZEB1, Tubβ3, and β-catenin in tissue samples from 34 idiopathic pulmonary fibrosis cases and 21 controls (5 normal lungs and 16 other interstitial lung diseases). In 100% idiopathic pulmonary fibrosis samples, the three proteins were concurrently expressed in fibroblastic foci, as well in damaged epithelial cells overlying these lesions and in pericytes within neo-angiogenesis areas. These results were also confirmed by immunofluorescence assay. In controls the abnormal expression of the three proteins was absent or limited. This is the first study that relates concurrent expression of Tubβ3, ZEB1, and β-catenin to abnormal epithelial and myofibroblast differentiation in idiopathic pulmonary fibrosis, providing indirect but robust evidence of miR-200 deregulation and epithelial to mesenchymal transition activation in idiopathic pulmonary fibrosis. The abnormal expression and localization of these proteins in bronchiolar fibro-proliferative lesions are unique for idiopathic pulmonary fibrosis, and might represent a disease-specific marker in challenging lung biopsies.

There are no available data for outcomes in children's idiopathic superior mesenteric artery syndrome (SMAS) strictly treated conservatively. The aim of the study was to evaluate clinical and nutritional outcome in children with idiopathic SMAS. A 1-year prospective observation study of effects of treatment and outcome was performed in 27 children (8 boys, 19 girls) with idiopathic SMAS who underwent an upper gastrointestinal (UGI) series, ultrasound measurement of the aortomesenteric angle, treatment, clinical assessment, growth evaluation, and regular clinical visits for more than 12 months. Mean age of the patients was 11.77 +/- 2.15 years. The major clinical complaints were postprandial pain or fullness (88.9%), vomiting (55.6%), and early satiety (51.9%). Eight patients (29.6%) had weight loss. The UGI series revealed typical features of SMAS. The aortomesenteric angle on ultrasound was 10 degrees to 19 degrees. The height of most patients (92.6%) was above the 10th percentile, whereas 15 (55.6%) patients weighed below the 10th percentile. Six patients underwent surgical intervention (3 for obstruction and 3 for persistent anorexia with weight loss), and their clinical symptoms and weight status improved steadily during the follow-up months. Among the 21 patients not subject to surgical intervention, 11 (52.4%) experienced a reduction of symptoms >50% after 3 months of treatment, and weight-for-age percentile increased significantly after 6 months of treatment. Overall, a significant increase in the weight-for-age status was seen in the patients with surgical treatment or with medication only after 6 and 12 months of treatment. An aortomesenteric angle children with idiopathic SMAS. A duodenojejunostomy can effectively relieve the obstructive symptoms, such as anorexia, and improve nutritional status, whereas long-term medical treatment may aid in relieving the clinical symptoms, promoting appetite, and improving nutritional status in pediatric patients with

Precision medicine is defined by the National Institute of Health's Precision Medicine Initiative Working Group as an approach to disease treatment that takes into account individual variability in genes, environment, and lifestyle. There has been increased interest in applying the concept of precision medicine to idiopathic pulmonary fibrosis, in particular to search for genetic and molecular biomarker-based profiles (so called endotypes) that identify mechanistically distinct disease subgroups. The relevance of precision medicine to idiopathic pulmonary fibrosis is yet to be established, but we believe that it holds great promise to provide targeted and highly effective therapies to patients. In this manuscript, we describe the field's nascent efforts in genetic/molecular endotype identification and how environmental and behavioral subgroups may also be relevant to disease management.

An unusual case of idiopathic multiple invasive cervical resorption

2014-01-01

Full Text Available Invasive cervical resorption is a rare form of root resorption, characterized by destruction of the cervical region of teeth resulting from the action of tooth resorbing cells. Being an asymptomatic condition, it is often discovered on routine radiographic examination. This multifactorial disease process can most commonly occur as a sequel to orthodontic treatment, dental trauma, bleaching procedures, and less commonly, as an outcome of segmental orthognathic surgery, periodontal root planning, tetracycline conditioning of the root canal, bruxism, transplantation of tooth, guided tissue regeneration, cementoenamel disjunction. In the absence of these predisposing factors, it can be labeled as ′idiopathic multiple cervical resorption′. This article describes the case of a medically fit Indian male, who displayed idiopathic invasive cervical resorption in multiple teeth.

Idiopathic granulomatous mastitis, also known as idiopathic granulomatous lobular mastitis, is a benign breast lesion that represents both a diagnostic and therapeutic dilemma. We report two cases of granulomatous mastitis recently evaluated and managed at our institution. To better understand this rare disease, we analyzed treatment outcomes in reported cases of granulomatous mastitis. One hundred sixteen cases were subsequently analyzed. Primary management strategies included observation (n = 9), steroids (n = 29), partial mastectomy (n = 75), and mastectomy (n = 3). Success rates with each treatment were observation, 56 per cent; steroids, 42 per cent; partial mastectomy, 79 per cent; and mastectomy, 100 per cent. Based on this analysis, we propose a clinically useful algorithm for both workup and management of these challenging cases.

Introduction: differentiating between ischemic cardiomyopathy and idiopathic dilated cardiomyopathy is important as coronary revascularization can improve prognosis in the ischemic subgroup. Due to inherent problems of coronary angiography in patients with depressed ejection fraction introducing a noninvasive tool to diagnose those who will benefit from angiography seems to be rewarding. We examined usefulness of myocardial perfusion scan in this group of patients. Materials and methods: study was performed on 64 patients (62 male and 2 female) aged 57.1 ± 6.7 y (mean ± SD) all with dilation of the left ventricular cavity and ejection fraction less than 40 % by echocardiography. Myocardial perfusion scan was performed in stress and rest phases. All the patients had coronary angiography which was used as the gold standard test. On each set of images, heart was arbitrary divided into 17 segments and perfusion abnormality in each segment was scored by a 5 grade scoring system (0-4). Summed stress Score was used as the scan criteria to differentiate dilated ischemic from idiopathic cardiomyopathy. Scores more than 17 were considered ischemic, and less than that, idiopathic. Results were compared with angiography. Results: from total 40 cases of ischemic cardiomyopathy (proved by angiography) 39 were correctly diagnosed by scan and only one case was mis categorized as idiopathic dilated cardiomyopathy . All 24 cases of idiopathic dilated cardiomyopathy were correctly diagnosed by scintigraphy. Sensitivity, specificity, positive predictive value, and negative predictive value of myocardial perfusion imaging for discrimination between ischemic and idiopathic dilated cardiomyopathy were 97.5 %, 100 %, 100 %, and 96 % respectively. Conclusion: Considering excellent accuracy of myocardial perfusion scan with scoring system in discrimination of ischemic dilated cardiomyopathy from idiopathic cardiomyopathy, this noninvasive test could be considered the main diagnostic test

A 40-year-old white man presented with fever, muscle pain, skin nodules and persistent hypereosinophilia over a period of 1 year. In addition, he had ventricular arrhythmias with episodes of tachycardia. Besides a lack of response to antiparasitic therapy, laboratory and pathological data excluded the diagnosis of trichinosis or any other parasitic infection. The patient's course of the disease over the previous 1 1 / 2 years was compatible with hypereosinophilic syndrome. In a muscle biopsy several eosinophilic perivascular and leucocytic intravascular infiltrates were found, indicative of muscle involvement by the disease. This is a report on the MRI findings of muscle involvement in idiopathic hypereosinophilic syndrome. (orig.)

Full Text Available Few trial-based assessments of ruxolitinib in patients with lower-risk myelofibrosis (MF have been conducted, and no studies have made such assessments in a real-world population. We assessed changes in spleen size and constitutional symptoms during ruxolitinib treatment using a retrospective, observational review of anonymized US medical record data of patients diagnosed with IPSS low-risk (n=25 or intermediate-1-risk (n=83 MF. The majority of patients were male (low risk, 60%; intermediate-1 risk, 69%. Most patients (92% and 77% were still receiving ruxolitinib at the medical record abstraction date (median observation/exposure time, 8 months. The proportion of patients with moderate or severe palpable splenomegaly (≥10 cm decreased from diagnosis (56% to best response (12%. Fatigue was reported in 47% of patients and was the most common constitutional symptom. For most symptoms in both risk groups, shifts in the distribution of severity from more to less severe from diagnosis to best response were observed. Both patients with low-risk and intermediate-1-risk MF experienced a substantial decrease in spleen size with ruxolitinib treatment in real-world settings. For most symptoms examined, there were distinct improvements in the distribution of severity during ruxolitinib treatment. These findings suggest that patients with lower-risk MF may benefit clinically from ruxolitinib treatment.

Primary myelofibrosis (PMF) is a Myeloproliferative Neoplasm (MPN) characterized by megakaryocyte hyperplasia, progressive bone marrow fibrosis, extramedullary hematopoiesis and transformation to Acute Myeloid Leukemia (AML). A number of phenotypic driver (JAK2, CALR, MPL) and additional subclonal mutations have been described in PMF, pointing to a complex genomic landscape. To discover novel genomic lesions that can contribute to disease phenotype and/or development, gene expression and copy number signals were integrated and several genomic abnormalities leading to a concordant alteration in gene expression levels were identified. In particular, copy number gain in the polyamine oxidase (PAOX) gene locus was accompanied by a coordinated transcriptional up-regulation in PMF patients. PAOX inhibition resulted in rapid cell death of PMF progenitor cells, while sparing normal cells, suggesting that PAOX inhibition could represent a therapeutic strategy to selectively target PMF cells without affecting normal hematopoietic cells' survival. Moreover, copy number loss in the chromatin modifier HMGXB4 gene correlates with a concomitant transcriptional down-regulation in PMF patients. Interestingly, silencing of HMGXB4 induces megakaryocyte differentiation, while inhibiting erythroid development, in human hematopoietic stem/progenitor cells. These results highlight a previously un-reported, yet potentially interesting role of HMGXB4 in the hematopoietic system and suggest that genomic and transcriptional imbalances of HMGXB4 could contribute to the aberrant expansion of the megakaryocytic lineage that characterizes PMF patients. © 2015 UICC.

Nocardia are ubiquitous environmental saprophytes that cause pneumonia and disseminated disease in immunocompromised patients. They can also cause localized cutaneous and soft tissue infections in healthy people after direct percutaneous inoculation. Nocardia arthritis is rare in both forms of the disease. Here we present the first published case of a child with septic arthritis caused by N brasiliensis. Importantly, this otherwise well 4-year-old girl had no known history of trauma but presented with transient cutaneous lesions and a 6-week history of arthritis involving the right fourth digit proximal interphalangeal joint without accompanying fever or raised systemic inflammatory markers. She received a diagnosis of juvenile idiopathic arthritis and underwent antiinflammatory and immunosuppressant therapy. After 2 months she developed frank septic arthritis, which necessitated a surgical joint washout, from which an intraoperative swab grew N brasiliensis. The patient received 6 months of high-dose trimethoprim-sulfamethoxazole and remains well more than 4 years after treatment. This unusual case highlights the importance of considering an indolent infection from slow-growing organisms, including Nocardia, when diagnosing the oligoarthritis subtype of juvenile idiopathic arthritis. This is especially relevant when a single joint is involved and response to antiinflammatory therapy is suboptimal because antiinflammatory agents may mask evolving signs of infection.

Idiopathic granulomatous lobular mastitis (IGLM) is a rare breast condition with prominent skin findings. It is typically seen in young parous women. Painful breast masses, draining sinuses, scarring, and breast atrophy are the main clinical manifestations. IGLM can resemble a variety of other inflammatory and neoplastic processes of the breast. It is thought to result from obstruction and rupture of breast lobules. Extravasated breast secretions then induce an inflammatory reaction. Corynebacteria have also been implicated in the pathogenesis. Treatment is surgical, but systemic corticosteroids, methotrexate, and antibiotics also play a role. © 2012 The International Society of Dermatology.

To determine the role of equine herpesvirus (EHV) in idiopathic keratoconjunctivitis in horses and to determine whether sample collection method affects detection of EHV DNA by quantitative polymerase chain reaction (qPCR). Twelve horses with idiopathic keratoconjunctivitis and six horses without signs of ophthalmic disease. Conjunctival swabs, corneal scrapings, and conjunctival biopsies were collected from 18 horses: 12 clinical cases with idiopathic keratoconjunctivitis and six euthanized controls. In horses with both eyes involved, the samples were taken from the eye judged to be more severely affected. Samples were tested with qPCR for EHV-1, EHV-2, EHV-4, and EHV-5 DNA. Quantity of EHV DNA and viral replicative activity were compared between the two populations and among the different sampling techniques; relative sensitivities of the sampling techniques were determined. Prevalence of EHV DNA as assessed by qPCR did not differ significantly between control horses and those with idiopathic keratoconjunctivitis. Sampling by conjunctival swab was more likely to yield viral DNA as assessed by qPCR than was conjunctival biopsy. EHV-1 and EHV-4 DNA were not detected in either normal or IKC-affected horses; EHV-2 DNA was detected in two of 12 affected horses but not in normal horses. EHV-5 DNA was commonly found in ophthalmically normal horses and horses with idiopathic keratoconjunctivitis. Because EHV-5 DNA was commonly found in control horses and in horses with idiopathic keratoconjunctivitis, qPCR was not useful for the etiological diagnosis of equine keratoconjunctivitis. Conjunctival swabs were significantly better at obtaining viral DNA samples than conjunctival biopsy in horses in which EHV-5 DNA was found. © 2015 American College of Veterinary Ophthalmologists.

According to the Scoliosis Research Society (SRS), idiopathic scoliosis (IS) is a curvature of more than 10° Cobb angle, affecting 2-3% of pediatric population. Idiopathic scoliosis accounts for 80% of all scoliosis cases. Non-operative principles in the therapy of idiopathic scoliosis, including Scoliosis Research Society (SRS) criteria and guidelines proposed by the experts of the Society on Scoliosis Orthopedic and Rehabilitation Treatment (SOSORTS) were presented. The possibility to carry out quality of life assessments in a conservative procedure was also demonstrated. Based on the natural history of idiopathic scoliosis, SRS criteria, SOSORT 2008 experts' opinion and the knowledge of the possibilities of psychological assessment of conservative IS treatment, rules were proposed regarding nonsurgical IS therapy procedures, with special consideration being paid to the proper treatment start time (age, Risser test, biological maturity, Cobb angle), possibility of curvature progression, the importance of physiotherapy and psychological assessment. The knowledge of SRS criteria and SOSORT guidelines regarding the conservative treatment of IS are essential for proper treatment (the right time to start treatment), and supports establishment of interdisciplinary treatment teams, consisting of a physician, a physiotherapist, an orthopedic technician and a psychologist.

The authors present a new posterior correction technique consisting of simultaneous double-rod rotation using 2 contoured rods and polyaxial pedicle screws with or without Nesplon tapes. The purpose of this study is to introduce the basic principles and surgical procedures of this new posterior surgery for correction of adolescent idiopathic scoliosis. Through gradual rotation of the concave-side rod by 2 rod holders, the convex-side rod simultaneously rotates with the the concave-side rod. This procedure does not involve any force pushing down the spinal column around the apex. Since this procedure consists of upward pushing and lateral translation of the spinal column with simultaneous double-rod rotation maneuvers, it is simple and can obtain thoracic kyphosis as well as favorable scoliosis correction. This technique is applicable not only to a thoracic single curve but also to double major curves in cases of adolescent idiopathic scoliosis.

The levels of 63 cytokines, chemokines, and growth factors were measured in the serum of four patients with idiopathic morphea and of one patient with vitamin K 1 -induced morphea employing a multiplex assay to identify the role of inflammatory/immunologic events in their pathogenesis. Full-thickness skin biopsies of affected skin were analyzed by histopathology. Luminex assays for 63 cytokines, chemokines, and growth factors were performed in the sera from four patients with idiopathic morphea and in two different samples of serum obtained in two separate occasions from one patient with vitamin K 1 -induced morphea. The serum values of numerous inflammatory cytokines and growth factors including IL-2, IL-4, IL-6, and IFNβ were markedly increased in the serum of patients with idiopathic morphea, whereas, these values were normal in the serum of the patient with vitamin K 1 -induced morphea. In contrast, serum eotaxin levels were greater than threefold higher in the patient with vitamin K 1 -induced morphea compared to patients with idiopathic morphea. The results demonstrated remarkable increases in the levels of numerous cytokines and chemokines in the serum samples of all patients with idiopathic morphea indicative of a prominent role of inflammatory/immunologic events in its pathogenesis. The results also showed statistically significant differences between idiopathic morphea and vitamin K 1 -induced morphea suggesting that their development involves different pathogenetic mechanisms.

Children with idiopathic apraxia experience difficulties planning the movements necessary for intelligible speech. There is increasing evidence that targeted early interventions, such as Prompts for Restructuring Oral Muscular Phonetic Targets (PROMPT), can be effective in treating these disorders. In this study, we investigate possible cortical thickness correlates of idiopathic apraxia of speech in childhood, and changes associated with participation in an 8-week block of PROMPT therapy. We found that children with idiopathic apraxia (n = 11), aged 3-6 years, had significantly thicker left supramarginal gyri than a group of typically-developing age-matched controls (n = 11), t(20) = 2.84, p ≤ 0.05. Over the course of therapy, the children with apraxia (n = 9) experienced significant thinning of the left posterior superior temporal gyrus (canonical Wernicke's area), t(8) = 2.42, p ≤ 0.05. This is the first study to demonstrate experience-dependent structural plasticity in children receiving therapy for speech sound disorders.

An idiopathic peptic ulcer is defined as an ulcer with unknown cause or an ulcer that appears to arise spontaneously. The first step in treatment is to exclude common possible causes, including Helicobacter pylori infection, infection with other pathogens, ulcerogenic drugs, and uncommon diseases with upper gastrointestinal manifestations. When all known causes are excluded, a diagnosis of idiopathic peptic ulcer can be made. A patient whose peptic ulcer is idiopathic may have a higher risk for complicated ulcer disease, a poorer response to gastric acid suppressants, and a higher recurrence rate after treatment. Risk factors associated with this disease may include genetic predisposition, older age, chronic mesenteric ischemia, smoking, concomitant diseases, a higher American Society of Anesthesiologists score, and higher stress. Therefore, the diagnosis and management of emerging disease should systematically explore all known causes and treat underlying disease, while including regular endoscopic surveillance to confirm ulcer healing and the use of proton-pump inhibitors on a case-by-case basis.
