    We report what is, to our best knowledge, the first case of chronic recurrent multifocal osteomyelitis (CRMO) in which the frontal and sphenoid bones were involved. Characterized by a prolonged and fluctuating course of osteomyelitis at different sites, CRMO is self-limited, although sequelae can oc

    The aim of this paper is to give a detailed description of the so-called "chronic recurrent multifocal osteomyelitis" (CRMO). The clinical, radiological and histopathological results of an analysis of 29 cases (15 children/adolescents and 14 adults) are presented and correlated to current data from the literature. We could delinate the following points: 1. CRMO is a systemic aseptic inflammation of the bone marrow (Osteitis), it can occur polytopically and association with pustulous dermatologic symptoms is possible. 2. It is not a rare disease 3. Osteomyelitis is probably "reactive" and a plasma-cell sclerotic process with ist own characteristic histologic three-phase course. 4. We could observe 5 specific types of localization which can be documented by X-ray or bone scan. 5. Accompanying arthritis os often present, especially "sympathetic coxitis". 6. The use of drugs in treatment of CRMO (i.e. azithromycin, calcitonin, and bisphosphonates) is discussed. In conclusion we want to point out, that 1. 99mTC bone scan should always be performed when there is suspicion for CRMO to reveal the pattern of affection, 2. the rheumatologist and dermatologist should be contacted, 3. operation is normally not necessary for treatment of the mostly self-limitin disease, and 4. the term "SAPHO syndrome" should be avoided, further differentiation of the diagnosis is necessary.

    Chronic recurrent multifocal osteomyelitis (CRMO) is an autoinflammatory bone disease occurring primarily in children and adolescents. Episodes of systemic inflammation occur due to immune dysregulation without autoantibodies, pathogens or antigen-specific T cells. CRMO is characterised by the insidious onset of pain with swelling and tenderness over the affected bones. Clavicular involvement was the classical description; however, the metaphyses and epiphyses of long bones are frequently affected. Lesions may occur in any bone, including vertebrae. Characteristic imaging includes bone oedema, lytic areas, periosteal reaction and soft tissue reaction. Biopsies from affected areas display polymorphonuclear leucocytes with osteoclasts and necrosis in the early stages. Subsequently, lymphocytes and plasma cells predominate followed by fibrosis and signs of reactive new bone forming around the inflammation. Diagnosis is facilitated by the use of STIR MRI scanning, potentially obviating the need for biopsy and unnecessary long-term antibiotics due to incorrect diagnosis. Treatment options include non-steroidal anti-inflammatory drugs and bisphosphonates. Biologics have been tried in resistant cases with promising initial results. Gene identification has not proved easy although research in this area continues. Early descriptions of the disease suggested a benign course; however, longer-term follow up shows that it can cause significant morbidity and longer-term disability. Although it has always been thought of as very rare, the prevalence is likely to be vastly underestimated due to poor recognition of the disease.

    Chronic recurrent multifocal osteomyelitis (CRMO) is an autoinflammatory disorder of children and young adults that is characterized by nonbacterial osteomyelitis. Patients typically present with multifocal bone pain secondary to sterile osseous inflammation, and the disease has a relapsing and remitting course. The cause of CRMO remains unclear, although the results of several studies have suggested a genetic component. The typical imaging findings of CRMO include lytic and sclerotic lesions in the metaphyses of long bones and the medial clavicles. Other common sites of disease are the vertebral bodies, pelvis, ribs, and mandible. CRMO is often bilateral and multifocal at presentation. Owing to the lack of a diagnostic test, CRMO remains a diagnosis of exclusion. Although generally a self-limiting disease, CRMO can have a prolonged course and result in significant morbidity. Radiologists can be the first to suggest this diagnosis given its characteristic radiographic appearance and distribution of disease. Radiologists should be familiar with the typical imaging findings of CRMO to prevent unnecessary multiple biopsies and long-term antibiotic treatment in children with CRMO.

    Chronic recurrent multifocal osteomyelitis (CRMO) is a rare non-infectious inflammatory bone disease of unknown aetiology. CRMO mainly affects the metaphyses of long bones and spine in children and young adolescents. It presents with recurrent episodes of bone pain and fever, resembling bacterial osteomyelitis, but cultures of lesions are sterile and it is unresponsive to antibiotic therapy. We report a case of a 3-year-old boy diagnosed with CRMO, who was initially treated for bacterial osteomyelitis, and received prolonged antibiotic therapy for chronic pain, and swelling of mandible and ulna. CRMO should be kept in mind in the differential diagnosis of chronic bone pain and osteomyelitis unresponsive to antibiotic treatment.

    Chronic non-bacterial osteomyelitis (CNO) in childhood and adolescence is a non-infectious autoinflammatory disease of the bone with partial involvement of adjacent joints and soft tissue. The etiology is unknown. The disease can occur singular or recurrent. Individual bones can be affected and multiple lesions can occur. Chronic recurrent multifocal osteomyelitis (CRMO) shows the whole picture of CNO. Accompanying but temporally independent of the bouts of osteomyelitis, some patients show manifestations in the skin, eyes, lungs and the gastrointestinal tract. The article gives an overview of the clinical manifestations, diagnostic procedures, and treatment options for CRMO involvement of the spine based on the current literature and our own cases.

    The authors undertook a retrospective review of the clinical records and radiologic findings of eight children with chronic, recurrent multifocal osteomyelitis (CRMO). This disease is a recognized clinicopathologic entity with typical radiographic findings, mostly in the metaphyses of the long bones. The diagnosis is one of exclusion without pathognomonic findings. The patients were treated with non-steroidal anti-inflammatory drugs. There was no evidence of altered bone growth or abnormal joint development. It is concluded that CRMO is a distinct clinical entity that is different from acute or subacute bacterial osteomyelitis. Recognition of this condition is important to avoid treatment with antibiotics and repeated operations.

    Full Text Available Study Design. A Case Report. Objective. We present a 15-year-old girl with an acute atypical scoliosis secondary to chronic recurrent multifocal osteomyelitis (CRMO. Summary of Background Data. CRMO is a rare nonpyogenic inflammatory bone condition with unclear aetiology. CRMO mainly affects the metaphyses of long bones, the pelvis, shoulder girdle, and less commonly the spine. Methods. Our case presented with a 6-month history of worsening thoracic back pain, asymmetry of her shoulders and abnormal posture. Whole spine radiographs revealed a right atypical thoracic scoliosis. Magnetic Resonance Imaging showed abnormal signal on the short TI inversion recovery (STIR sequences in multiple vertebrae. A bone biopsy demonstrated evidence of fibrosis and chronic inflammatory changes. Interval MRI scans revealed new oedematous lesions and disappearance of old lesions. Symptoms improved. Results. It is important to consider CRMO as an acute cause of atypical scoliosis. Malignancy, pyogenic infections and atypical presentations of juvenile arthritis need excluding. Conclusion. This 24-month follow-up describes a rare cause of an atypical scoliosis and fortifies the small amount of the currently available literature. The case highlights the relapsing and remitting nature of CRMO with new lesions developing and older lesions burning out. We advise close radiological surveillance and symptomatic management.

    Chronic recurrent multifocal osteomyelitis (CRMO) is a diagnosis of exclusion primarily in children and adolescents. As part of the essential criteria for the diagnosis of CRMO, multifocal lesions must be identified. We present the case of an 11-year-old boy with CRMO, whose diagnosis was facilitated by the use of whole body magnetic resonance imaging (WBMR), but not isotope bone scanning.

    Two case reports of recurrent multifocal periostitis in two girls aged 15 and 16 are added to the eight cases already reported in the literature. The disease is characterised clinically by recurrent mesomelic swelling of the extremities and radiologically by periosteal thickening and sclerosis of underlying bone. Hyperglobulinaemia is the most constant biochemical finding. The bone biopsy shows no typical features. The possibility of a viral etiology is discussed.

    We present the case of a 33-year-old man with no significant medical history who developed right scapular pain, left-sided sacroiliac joint pain, and lower back pain, and was eventually diagnosed with chronic recurrent multifocal osteomyelitis (CRMO). Imaging demonstrated multiple scattered T2-hyperintense lesions on MRI at the spine and the left SI joint, some of which progressed and one regressed in size on follow-up. Histopathology demonstrated only non-specific chronic inflammation compatible with CRMO. No evidence of infectious organisms or neoplastic processes was found. The pain was relapsing and remitting in nature. Laboratory investigations were notable for no evidence of hematologic malignancy or infection, but only a mild increase in alkaline phosphatase. This case highlights that CRMO, despite being thought of as a childhood-onset disease, can present in adults as well, and also provides illustrative examples of imaging and histological findings.

    Chronic recurrent multifocal osteomyelitis (CRMO) is a rare disease of unknown etiology characterized by multiple osteomyelitic changes in the predominantly metaphysial regions of long bones. It was first described by Giedon et al. in 1972. Cultures for all known microorganisms are negative. Pain is the most common symptom, and sometimes soft tissue swelling is present. Patients are usually treated with nonsteroidal antiinflammatory drugs (NSAIDs) or corticosteroids and respond, at least partly, to these treatments. CRMO is most commonly seen in children and is in the majority of cases self-limiting but has a protracted course of several years. Some patients have a more prolonged disease period, as in the patient reported here. Treatment with corticosteroids in children has the risk of causing growth retardation as a potential adverse effect, and alternative treatments are of great interest. In the actual paper, a successful treatment with interferon-alpha 2b in a 34-year-old man with CRMO is presented.

    Chronic recurrent multifocal osteomyelitis (CRMO) is an inflammatory disorder that primarily affects children. Its hallmark is recurring episodes of sterile osteomyelitis. The clinical presentation is insidious onset of bone pain with or without fever. Laboratory studies typically reveal nonspecific evidence of inflammation. Radiologic imaging and histologic appearance resemble those of infectious osteomyelitis. There is a strong association with inflammatory disorders of the skin and intestinal tract in affected individuals and their close relatives, suggesting a shared pathophysiology and supporting a genetic component to disease susceptibility. Two genetic syndromes have CRMO as a prominent phenotype-Majeed syndrome and deficiency of the interleukin-1 receptor antagonist-and suggest that interleukin-1 may be a key cytokine in disease pathogenesis. This review briefly summarizes the main clinical and radiologic aspects of the disease and then focuses on genetics and pathophysiology and provides an update on treatment.

    An 11-year-old boy was diagnosed with chronic recurrent multifocal osteomyelitis (CRMO) and presented with right sacro-femoral and occipital lesions. Initially, a tumor was suspected. However, the bone biopsy showed osteomyelitis with a negative bacterial culture. Bone scintigraphy revealed inflammatory changes on multiple bone lesions. The slight elevation in inflammatory markers such as C-reactive protein was of little clinical value. He was diagnosed with CRMO by sacral biopsy, and the clinical course progressed, with the presence of a new occipital lesion observed after the 1-year follow-up. The administration of non-steroidal anti-inflammatory drugs successfully improved his clinical symptoms. The presence of a skull lesion in the occipital bone of a pediatric patient with CRMO has not been previously reported.

    Initial presentation with primary spinal involvement in chronic recurrent multifocal osteomyelitis of childhood (CRMO) is rare. Our objective was to review the imaging appearances of three patients who had CRMO who initially presented with isolated primary spinal involvement.Design and patients The imaging, clinical, laboratory and histology findings of the three patients were retrospectively reviewed. Imaging included seven spinal MR imaging scans, one computed tomography scan, nine bone scans, two tomograms and 16 radiographs. These were reviewed by two musculoskeletal radiologists and a consensus view is reported. All three patients presented with atraumatic spinal pain and had extensive bone spinal pathology. The patients were aged 11, 13 and 12 years. There were two females and one male.Results and conclusions The initial patient had thoracic T6 and T8 vertebra plana. Bone scan showed additional vertebral body involvement. Follow-up was available over a 3 year period. The second patient had partial collapse of T9 and, 2 years later, of C6. Subsequently extensive multifocal disease ensued and follow-up was available over 8 years. The third patient initially had L3 inferior partial collapse and 1 year later T8 involvement with multifocal disease. Follow-up was available over 3 years. The imaging findings of the three patients include partial and complete vertebra plana with a subchondral line adjacent to endplates associated with bone marrow MR signal alterations. Awareness of the imaging appearances may help the radiologist to include this entity in the differential diagnosis in children who present with spinal pathology and no history of trauma. Histopathological examination excludes tumor and infection but with typical imaging findings may not always be necessary. (orig.)

    Chronic recurrent multifocal osteomyelitis (CRMO) is a disease of children and young adults. Clinically, the disease is characterized by the insidious onset of local pain and swelling in affected bones. Its course is one of intermittent periods of exacerbation and remission with successive bones affected. The pathogenesis of CRMO remains unknown, although an autoinflammatory disorder may be the cause, with inflammation of bone. This lesion is radiologically characterized as multiple lucencies surrounded by defined zones of patchy but dense sclerosis, cortical thickening from periosteal new bone formation, and increased bone size with different bones involved. Multiple therapeutic regimens had shown only a partial or temporary response. Because indomethacin has been successfully applied in inhibition of ossification and inflammatory processes, we initiated therapy with indomethacin in patients with CRMO. We report on the cases of 5 patients who responded dramatically to treatment with indomethacin. All underwent progressive clinical improvement (mean, 2.8 months). Radiological lesions disappeared after a mean period of 10.5 months. In 1 case where treatment was started late, small osteolytic zones persisted but with no clinical consequences. There were no additional recurrences or new bones affected during follow-up period (mean, 4 years). Our observation indicates that indomethacin may be an effective treatment for CRMO.

    Chronic recurrent multifocal osteomyelitis (CRMO) is an autoinflammatory bone disease of unknown etiology. It affects children and adolescents predominantly and occurs mostly in the female population. It is characterized by the insidious onset of pain and swelling, with a fluctuating clinical course of relapses and remissions. Typically, several bones are affected, either synchronously or metachronously, and bilateral involvement is common. CRMO most commonly affects the metaphysis of long bones, especially the tibia, femur, and clavicle. The spine, pelvis, ribs, sternum, and mandible may also be affected. Although lesions are mostly multiple, patients may present with a single symptomatic focus. Radiographic findings may be negative early in the course of the disease. Bone scintigraphy is useful in determining the presence of abnormality and the extent of disease. The imaging and clinical features of CRMO overlap with those of infectious osteomyelitis, bone malignancy, and inflammatory arthritis. Nonetheless, CRMO can be confidently diagnosed with the recognition of typical imaging patterns in the appropriate clinical setting. This article reviews imaging findings with special emphasis on bone scintigraphy and specific disease sites.

    There are only a few studies that address the frequency and type of spinal involvement in patients with chronic recurrent multifocal osteomyelitis (CRMO) as well as the outcome of these patients treated with pamidronate (PAM). We performed a retrospective study on patients with CRMO and analyzed clinical and pain assessments as well as regional and whole body MRI findings and compared with posttreatment findings. Of 102 children and adolescents with CRMO, 27 (26%) had involvement of the spine. Vertebral deformities were seen in 14 of these 27 patients, scoliosis or kyphosis in 6. After routine whole body MRI, 19 complained of back pain, whereas eight were asymptomatic with spinal lesions detected incidentally. A total of 72 spinal lesions were detected, thoracic vertebrae being the most commonly affected. Seven patients were treated with PAM; all of whom had vertebral deformities and ongoing back pain. Pain resolution was achieved within 3 months of PAM treatment in every case. One patient subsequently developed a pain amplification syndrome. Repeat MRI performed at a mean interval of 13 months revealed partial or complete resolution of vertebral hyperintensities in every patient. Improvement of vertebral height was seen in a total of three vertebrae in two patients. Severe side effects were not observed. In conclusion, we demonstrated that spinal involvement and associated vertebral deformities with or without kyphoscoliosis are not rare in CRMO, and PAM appears to be an effective and safe treatment for this condition. Although controlled studies are urgently needed, the use of PAM for refractory CRMO with extended spinal involvement (vertebral deformities, kyphosis, and scoliosis) should be considered, especially after failing of conventional therapy.

    Chronic recurrent multifocal osteomyelitis (CRMO) is a systemic osteo-articular disease that is characterized by a sterile, primarily chronic osteomyelitis with various distribution patterns of the individual lesions. In this article, we describe the 'axial type' with predominant involvement of the spine, which represents 13 of our 41 CMRO cases of different age groups. The important element of its diagnosis is the typical lympho-plasmacellular spondylitis that can be detected and staged by scintigraphy, MRI and conventional radiography. Potentially affected are all vertebrae from the mid-cervical spine to the sacrum. One or several segments can be involved, sometimes as transient inflammatory edema, sometimes as 'migratory spondylitis' or 'saltatory spondylitis', but also as chronic sclerosing type with early radiographically detectable manifestation. Vertebral deformity due to compression and total collapse (vertebra plana) are rare. A complicated course with patulous perivertebral edema can lead to concomitant symptomatic inflammatory changes in adjacent regions and organs. In the course of CRMO, spondylodiscitis only develops as secondary destruction following the spondylitis. This can help to differentiate spondyloarthropathies from CRMO that is initially detected as primary lesion in the spine. While CRMO generally has a good prognosis, its radiological differentiation from rheumatology conditions plays an important role. (orig.)

    We have studied retrospectively a series of 10 children presenting with chronic multifocal osteomyelitis (8 girls, 2 boys, 7 to 16 years). All patients had plain films, bone scintigraphies and histological studies. Three had CT scan and/or MRI. Compared with literature data, we observed only one case of palmo-plantar pustulosis and only 2 cases of lysis of the medial extremity of the clavicle; in addition, we report one case of lateral extremity of the clavicle and 2 vertebral locations. The radiological pattern was typical: at the beginning of the disease, plain films showed lytic areas which became progressively osteosclerotic with enlargement of the bone. In all the cases, bone scintigraphy revealed high uptake areas which were often infra-clinical. The diagnosis was delayed from 3 months to 3 years. This emphasizes the difficulty of the diagnosis which relies on the association of clinical, biological and radiological elements. Biopsies are required to rule out an infectious bacterial osteomyelitis or a tumoral process. The pathogenesis of OCMR remains unknown, but the relation with the SAPHO (synovitis, acne, pustulosis, Hyperostosis, osteitis) syndrome is general accepted because of the similar features of the osteitis. The long term follow up appears to be uncertain: 6 of our patients are still symptomatic after five years despite anti inflammatory treatment. (authors). 22 refs.

    Chronic recurrent multifocal osteomyelitis is a rare disorder that affects children and teenagers. Clinically, it is characterized by insidious onset of local swelling and pain in several metaphyses. A symmetric, recurrent and multifocal pattern is usual. Spinal involvement is possible. Inconstant association with a cutaneous affection (palmo-plantar pustulosis, acne fulminans, psoriasis), or less frequently with an inflammatory chronic gut disorder is described. Pathogenesis usually recognized is an enthesopathy. Enthesitis may progress to the osseous part of the enthese and produce an aseptic chronic osteomyelitis. Biopsy specimen with culture is certainly necessary to rule out bacterial osteomyelitis and bone tumor. It is particularly true when the bone lesion is isolated. Disease course is benign and self-limited. The clinical course is characterized by recurrences and remissions occurring for 6 to 10 years. Treatment based on non steroid anti-inflammatory drugs is usually effective. (authors). 17 refs.

    A growing body of literature has identified the association between neutrophilic dermatoses and multifocal, aseptic bone lesions in children, termed chronic recurrent multifocal osteomyelitis (CRMO). Classically, patients present with swelling, pain, and impaired mobility of the affected area, with skin lesions developing concurrently or in the future. Bone biopsy reveals inflammatory changes consistent with infectious osteomyelitis, but cultures and histologic staining invariably fail to identify an infectious source. Patients are refractory to antibiotic therapy, but dramatically respond to systemic steroids and may need to be maintained on low-dose steroids to prevent relapse. Numerous authors have suggested that CRMO and synovitis, acne, pustulosis, hyperostosis, osteitis (SAPHO) syndrome lie along the same clinical spectrum. In fact some believe that CRMO is the pediatric presentation of SAPHO. The two syndromes share numerous characteristics, including osteitis, a unifocal or multifocal presentation, hyperostosis, and pustulosis, which all occur in a generally healthy individual. Our seven patients, five of whom were diagnosed with CRMO, and two of whom were diagnosed with SAPHO syndrome further strengthen the idea that CRMO and SAPHO syndrome do indeed lie along the same clinical spectrum. In addition, we include two rare cases of pediatric Sweet's syndrome with evidence of pathergy.

    Full Text Available OBJETIVO: Relatar três casos de osteomielite crônica multifocal recorrente de mandíbula. A osteomielite crônica multifocal recorrente é uma doença inflamatória, com acometimento de um ou mais ossos, sem patógenos isolados nas áreas afetadas, sendo o envolvimento da mandíbula raramente descrito na literatura. DESCRIÇÃO: Caso 1 - paciente feminina, com 13 anos, após tratamento dentário evoluiu com dor mandibular e febre. A paciente foi tratada com antibióticos por osteomielite, evoluindo com aumento progressivo da mandíbula e pustulose palmoplantar. A cintilografia óssea mostrou hipercaptação difusa da mandíbula. A redução da tumoração mandibular foi evidenciada com a indometacina e sessões de câmara hiperbárica. Caso 2 - paciente feminina, com 9 anos, apresentou dor e edema em região de mandíbula direita recorrente por três anos. O diagnóstico de osteomielite foi realizado e introduzido amoxicilina. Após três meses, a tomografia computadorizada mostrou osteólise mandibular difusa. Indometacina e câmara hiperbárica foram introduzidas, porém a paciente apresentou recidiva e foi tratada com prednisona, rofecoxib e metotrexato.

    Full Text Available Multifocal osteonecrosis is a relatively rare disorder with an estimated incidence of around 3% among patients diagnosed as having osteonecrosis. Multifocal osteonecrosis is caused by the several conditions including corticosteroid treatment, coagulation disorders, connective tissue disorders including systemic lupus erythematosus (SLE, inflammatory bowel disease, renal transplantation, and underlying malignancies. Alcohol abuse is one of the risk factors for osteonecrosis, and alcohol-induced osteonecrosis is 5% among all the osteonecrosis. Furthermore, the overall incidence of alcohol-induced multifocal osteonecrosis was approximately 6% among all the osteonecrosis induced by the alcohol. Therefore, here, we report an extremely rare case of alcohol-induced multifocal osteonecrosis involving three joints (two knees and one hip and review the related literature.

    Full Text Available Purpose: To report an unusual case of multifocal bacterial keratitis that despite success-ful treatment caused chronic ocular hypertension. Methods: A 67-year-old woman with unilateral multifocal keratitis and no previous ocular pathology was admitted to our hospital. Corneal scrapings and conjunctival samples were obtained for culture and the patient received intensive therapy with fortified vancomycin and tobramycin eye drops. Results: The cultures demonstrated two strains of Staphylococcus epidermidis, one resistant to ciprofloxacin and both sensitive to vancomycin. Treatment was effective and gradually discontinued after total cessation of the inflammatory activity. During the follow-up period, the patient developed late and persistent ocular hypertension of unknown etiology, in absence of any detectable inflammation or complication, and received permanent antiglaucoma therapy. Conclusion: Differential diagnosis between fungal and bacterial infection is critical in cases of multifocal keratitis. Patients with multifocal bacterial keratitis may need intraocular pressure monitoring, even after complete infection healing.

    2007-01-01

    Full Text Available Abstract Background Hypophosphatasia (HP is characterized by a genetic defect in the tissue-nonspecific alkaline phosphatase (TNSALP gene and predominantly an autosomal recessive trait. HP patients suffer from reduced bone mineralization. Biochemically, elevated concentrations of substrates of TNSALP, including pyridoxal-5'-phosphate and inorganic pyrophosphate occur in serum, tissues and urine. The latter has been associated with chronic inflammation and hyperprostaglandinism. Case presentation We report on 2 affected children presenting with multifocal inflammatory bone lesions mimicking malignancy: A 6 years old girl with short stature had been treated with human growth hormone since 6 months. Then she started to complain about a painful swelling of her left cheek. MRI suggested a malignant bone lesion. Bone biopsy, however, revealed chronic inflammation. A bone scan showed a second rib lesion. Since biopsy was sterile, the descriptive diagnosis of chronic non-bacterial osteomyelitis (CNO was established. The diagnostic tests related to growth failure were repeated and subsequent analyses demonstrated a molecular defect in the TNSALP gene. The second girl (10 years old complained about back pain after she had fallen from her bike. X rays of her spine revealed compressions of 2 thoracic vertebrae. At first these were considered trauma related, however a bone scan did show an additional lesion in the right 4th rib. A biopsy of this rib revealed a sterile lympho- plasmocytoid osteomyelitis suggesting multifocal CNO. Further analyses did show a decreased TNSALP in leukocytes and elevated pyridoxal phosphate in plasma, suggesting a heterozygous carrier status of HP. Conclusion Chronic bone oedema in adult HP and chronic hyper-prostaglandinism in childhood HP do suggest that in some HP patients bone inflammation is present in conjunction with the metabolic defect. Sterile multifocal osteomyelitis could be demonstrated. Non-steroidal anti

    Chronic recurrent multifocal osteomyelitis (CRMO) is an autoinflammatory disorder that primarily affects bone but is often accompanied by inflammation of the skin and/or gastrointestinal tract. The etiology is unknown but evidence suggests a genetic component to disease susceptibility. Although most cases of CRMO are sporadic, there is an autosomal recessive syndromic form of the disease, called Majeed syndrome, which is due to homozygous mutations in LPIN2. In addition, there is a phenotypically similar mouse, called cmo (chronic multifocal osteomyelitis) in which the disease is inherited as an autosomal recessive disorder. The cmo locus has been mapped to murine chromosome 18. In this report, we describe phenotypic abnormalities in the cmo mouse that include bone, cartilage and skin inflammation. Utilizing a backcross breeding strategy, we refined the cmo locus to a 1.3 Mb region on murine chromosome 18. Within the refined region was the gene pstpip2, which shares significant sequence homology to the PSTPIP1. Mutations in PSTPIP1 have been shown to cause the autoinflammatory disorder PAPA syndrome (pyogenic arthritis, pyoderma gangrenosum and acne). Mutation analysis, utilizing direct sequencing, revealed a single base pair change c.293T --> C in the pstpip2 gene resulting in a highly conserved leucine at amino acid 98 being replaced by a proline (L98P). No other mutations were found in the coding sequence of the remaining genes in the refined interval, although a 50 kb gap remains unexplored. These data suggest that mutations in pstpip2 may be the genetic explanation for the autoinflammatory phenotype seen in the cmo mouse.

    We report a case of primary multifocal osseous lymphoma in a 6-year-old girl presenting with multifocal osteolytic lesions without systemic symptoms or identifiable non-osseous primary tumor. The differential diagnoses for such a presentation include histiocytosis X, chronic recurrent multifocal osteomyelitis, acute lymphoblastic leukemia, metastatic disease, and primary bone lymphoma. Although non-Hodgkin lymphoma is common in the pediatric population, its presentation as a primary bone tumor, especially with multifocal disease, is extremely rare and is frequently misdiagnosed. We hope that awareness of this entity will help radiologists achieve timely diagnosis and intervention. (orig.)

    Fungal infections are common in solid organ transplantation. An increasing number of transplant recipients receive antifungal therapy for prolonged duration owing to invasive fungal infections. Herein, we describe a diagnosis of periostitis as a complication of chronic use of voriconazole in a lung transplant recipient. The patient was diagnosed with probable pulmonary aspergillosis and was treated with oral voriconazole for a total of 9 months. Evidence of multifocal periostitis was observed in the axial and appendicular skeleton. Early recognition of this phenomenon is important to prevent unnecessary tests and procedures. Prompt discontinuation of voriconazole should result in improvement of symptoms.

    Pancreatitis can manifest as a one-time episode, recurring attacks, or chronic pain. It is caused by numerous factors ranging from alcohol consumption to gallstones to subtle obstructive causes and occult autoimmune disorders. As a result, determining the etiology and effectively treating the causes and consequences of pancreatitis can be challenging. This article reviews the diagnosis and management of acute, acute recurrent, and chronic pancreatitis, focusing on more challenging scenarios.

    Full Text Available The quantitative ultrasound characteristics (USC of the median, ulnar nerve at different levels and the spinal nerves in patients with multifocal motor neuropathy (MMN; n=13; 40,4 ± 12,6 years old and chronic inflammatory demyelinating polyneuropathy (CIDP; n = 7; 47,3 ± 11,2 year old did not reveal statistical difference in cross sectional area (CSA between analyzed groups. Patients with MMN have more pronounced asymmetry of CSA in comparison with CIDP patients which have a symmetrical pattern of diffuse nerve involvement. Quantitative USC has shown to be not informative enough in differentiation of MMN and CIDP. The qualitative analysis (QA according to 3 described types of nerve changes has shown that CIDP is characterized by the prevalence of type 3 pattern (85.8 % while MMN – by type 2 (69.2 %. The sensitivity and specificity of proposed QA patterns in nerve USC need to be analyzed in additional investigations.

    Intravenous immunoglobulin [IVIg], plasma exchange [PE], and corticosteroids are efficacious treatment in chronic inflammatory demyelinating polyneuropathy [CIDP]. IVIg is effective in multifocal motor neuropathy [MMN]. NIS, NIS-weakness, sum scores of raw amplitudes of motor fiber (CMAPs) amplitudes, and Dyck/Rankin score provided reliable measures to detect and scale abnormality and reflect change; they are therefore ideal for office management of response-based immunotherapy (R-IRx) of CIDP. Using efficacious R-IRx, a large early and late therapeutic response (≥ one-fourth were in remission or had recovered) was demonstrated in CIDP. In MMN only an early improvement with late non-significant worsening was observed. The difference in immunotherapy response supports a fundamental difference between CIDP (immune attack on Schwann cells and myelin) and MMN (attack on nodes of Ranvier and axons).

    Full Text Available Background: Abdominal epilepsy (AE is an uncommon cause for chronic recurrent abdominal pain in children and adults. It is characterized by paroxysmal episode of abdominal pain, diverse abdominal complaints, definite electroencephalogram (EEG abnormalities and favorable response to the introduction of anti-epileptic drugs (AED. We studied 150 children with chronic recurrent abdominal pain and after exclusion of more common etiologies for the presenting complaints; workup proceeded with an EEG. We found 111 (74% children with an abnormal EEG and 39 (26% children with normal EEG. All children were subjected to AED (Oxcarbazepine and 139 (92% children responded to AED out of which 111 (74% children had an abnormal EEG and 27 (18% had a normal EEG. On further follow-up the patients were symptom free, which helped us to confirm the clinical diagnosis. Context: Recurrent chronic abdominal pain is a common problem encountered by pediatricians. Variety of investigations are done to come to a diagnosis but a cause is rarely found. In such children diagnosis of AE should be considered and an EEG will confirm the diagnosis and treated with AED. Aims: To find the incidence of AE in children presenting with chronic recurrent abdominal pain and to correlate EEG findings and their clinical response to empirical AEDs in both cases and control. Settings and Design: Krishna Institute of Medical Sciences University, Karad, Maharashtra, India. Prospective analytical study. Materials and Methods: A total of 150 children with chronic recurrent abdominal pain were studied by investigations to rule out common causes of abdominal pain and an EEG. All children were then started with AED oxycarbamezepine and their response to the treatment was noted. Results: 111 (74% of the total 150 children showed a positive EEG change suggestive of epileptogenic activity and of which 75 (67.56% were females and 36 (32.43% were male, majority of children were in the age of group of 9

    Full Text Available Pain is not merely a symptom of disease but a complex independent phenomenon where psychological factors are always present (Sternberg, 1973. Especially by chronic, recurrent pain it's more constructive to think of chronic pain as a syndrome that evolves over time, involving a complex interaction of physiological/organic, psychological, and behavioural processes. Study of chronic recurrent functional pain covers tension form of headache. 50 suffering persons were accidentally chosen among those who had been seeking medical help over more than year ago. We tested their pain intensity and duration, extent of subjective experience of accommodation efforts, temperament characteristics, coping strategies, personal traits, the role of pain in intra- and interpersonal communication. At the end we compared this group with control group (without any manifest physical disorders and with analyse of variance (MANOVA. The typical person who suffers and expects medical help is mostly a woman, married, has elementary or secondary education, is about 40. Pain, seems to appear in the phase of stress-induced psychophysical fatigue, by persons with lower constitutional resistance to different influences, greater irritability and number of physiologic correlates of emotional tensions. Because of their ineffective style of coping, it seems they quickly exhausted their adaptation potential too. Through their higher level of social–field dependence, reactions of other persons (doctor, spouse could be important factors of reinforcement and social learning processes. In managing of chronic pain, especially such as tension headache is, it's very important to involve bio-psychosocial model of pain and integrative model of treatment. Intra- and inter-subjective psychological functions of pain must be recognised as soon as possible.

    Full Text Available ronic inflammation of the alveolar bone is a great clinical and radiologic mimic, which merits recognition by the clinician and pathologist. The patient can thus be reassured of the proper early treatment and a favorable prognosis. Occasionally, it is difficult to differentiate inflammatory lesions from malign-ant tumors. The aim of this report is to present a case with an inflammatory lesion mimicking malignant condition.We report a 19-year-old male complaining of rapid onset gingival swelling of the right side of both jaws and looseness of the right upper molar teeth in 20 days. Based on the acute onset of the gingival hyperplasia, severe looseness of the affected teeth especially in the maxilla, and the patient's age, multifocal rapid growing malignant condition was not ruled out. The lesion was misdiagnosed as a malignant condition by clinical and radiographic examination. The whole body bone scan showed no significant increased uptake in the right oral cavity compatible with no active bony pathology. The surgical pathology findings of the lesion showed severe chronic inflammation with surface epithelial hyperplasia.The initial diagnosis of the lesion was malignant condition but it was ruled out by bone scan and histological appearance.

Immunomodulatory therapy may provide benefit, as treatment of mice with dexamethasone during acute UTI improved outcome by reducing the development of chronic cystitis, which predisposes to recurrent infection. Here we discovered soluble biomarkers engaged in myeloid cell development and chemotaxis that were predictive of future UTI recurrence when elevated in the sera of young women with UTI. Translation of these findings revealed that temperance of the neutrophil response early during UTI, and specifically disruption of bladder epithelial transmigration of neutrophils by inhibition of cyclooxygenase-2, protected mice against chronic and recurrent cystitis. Further, proteomics identified bladder epithelial remodeling consequent to chronic infection that enhances sensitivity to neutrophil damage. Thus, cyclooxygenase-2 expression during acute UTI is a critical molecular trigger determining disease outcome and drugs targeting cyclooxygenase-2 could prevent recurrent UTI.

    Full Text Available Osteomyelitis of the maxillofacial skeleton is a rare condition in recent times. The combination of antibiotic therapy and surgical debridement is effective in the treatment of chronic suppurative osteomyelitis (CSO. This case report describes the successful surgical treatment of CSO of the mandible in an 18-year-old adult. Treatment included a pre-surgical course of antibiotics followed by sequestrectomy, resection of the coronoid process and removal of the pathologically fractured condylar process of the left side of the mandible. On post-operative clinical review at 1 week, the extra oral draining sinus healed with improved mouth opening.

    Full Text Available Objective. This cross-sectional study analyzes the pattern of ultrasound peripheral nerve alterations in patients with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP and multifocal motor neuropathy (MMN at different stages of functional disability. Material and Methods. 22 CIDP and 10 MMN patients and a group of 70 healthy controls were evaluated with an ultrasound scan of the median, ulnar, peroneal, tibial, and sural nerves. Results were correlated with clinical disability scales and nerve conduction studies. Results. Patients with intermediate functional impairment showed relatively larger cross-sectional areas than subjects with either a milder (p<0.05 or more severe impairment (p<0.05, both in CIDP and in MMN. In addition, MMN was associated with greater side-to-side intranerve variability (p<0.05, while higher cross-sectional areas were observed in CIDP (p<0.05 and in nerve segments with predominantly demyelinating features (p<0.05. Higher CSA values were observed in nerves with demyelinating features versus axonal damage (p<0.05 for CIDP; p<0.05 for MMN. Discussion and Conclusions. Greater extent of quantitative and qualitative US alterations was observed in patients at intermediate versus higher functional disability and in nerves with demyelinating versus axonal damage. CIDP and MMN showed differential US aspects, with greater side-to-side intranerve variability in MMN and higher cross-sectional areas in CIDP.

    2003-01-01

    Objective: To sum up the causes of recurrence of chronic subdural hematoma (CSDH) from failure of trepanation and drainage and explore its prevention and treatment.Methods: From October 1988 to June 2002 a total of 358 patients with CSDH were treated with trepanation and drainage in our hospital. Among them 15 patients had recurrence of CSDH after operation. The data of the 15 patients were reviewed retrospectively.Results: Of the 15 patients, 13 were cured by retrepanation and redrainage, one cured by removal of hematoma by craniotomy with bone flap, and one, a 1-year old child, gave up reoperation due to severe encephalatrophy. Conclusions: Most CSDHs which recur after trepanation and drainage can be cured by retrepanation and redrainage. For the patients with repeated recurrence of CSDH removal of hematoma capsule can be considered. The causes of recurrence of CSDH are related to disease course, the thickness of hematoma capsule, the severity of encephalatraphy and whether the hematoma cavity is drained or irrigated completely, and operation methods.

    We present data of 2 patients suffering from chronic motor-sensory multifocal neuropathy with persistent conduction block. The first case concerns a 9-year follow-up of a female, aged 24 years at onset with persistent multiple conduction blocks and a tendency towards generalization of clinical deficits. Eight years after onset sural nerve biopsy revealed extreme interfascicular variations of de/remyelination, onion bulb formation, fiber loss, edema, and proliferation of basal lamina of endoneurial capillaries. Serum antibodies against GM1 gangliosides were not detected. The second case, a 29-year-old Yemenitic male with a 5-year history, exhibited conduction blocks in motor and sensory fibers, and a normal sural nerve biopsy. Our results are discussed with respect to those of some 30 cases individually reported in the literature.

    Infantile chronic recurrent parotitis (ICRP) has been attributed to multiple causes, including viral infections, and therefore its treatment remains empirical. Our aim was to evaluate the involvement of respiratory and oropharyngeal viruses in acute episodes of ICRP. Seventy children were studied, 50 patients and 20 age-matched controls, in a 2-year follow-up study. Saliva samples were taken from the parotid duct and analyzed by viral isolation and immunofluorescence for adenovirus (Ad), respiratory sincitial virus (RSV), parainfluenza virus (PI), influenza virus (Flu), Cytomegalovirus (CMV), and herpes simplex virus (HSV). Paired sera samples were tested by ELISA for anti-Epstein-Barr virus (EBV) IgG and anti-mumps IgM and IgG. Viral infections were detected in 7/50 (14%) cases of the ICRP group: one CMV; 2 Enteroviruses isolated in human embryonic lung fibroblast cells; 1 Flu A; and 3 mumps virus. No EBV seroconversions were detected. In the control group, 2 out of the 20 children had an asymptomatic mumps positive IgM titer. Our data indicate that the main respiratory and oropharyngeal viruses are not the cause of acute episodes of ICRP in Chilean children.

    Full Text Available Cryptogenic Multifocal Ulcerous Stenosing Enteritis (CMUSE is a rare idiopathic disease of the small bowel. Its origin and pathophysiology has not been well described. Clinicopathologic features include unexplained ileal strictures with supercial ulceration. We present a case of a 31-year-old HIV positive lady who was admitted with complaints of recurrent abdominal pain and constipation. Laboratory investigations revealed iron deciency anemia. Ultrasonography of the abdomen showed dilated bowel loops and a subsequent barium follow through showed ve strictures in the ileum. Segmental small bowel resection with end-to-end anastomosis was performed. Grossly ileum showed ve ileal strictures. The diagnosis of CMUSE was made on histopathology after ruling out other causes of strictures. The present case highlights the importance of considering CMUSE in patients with chronic or recurrent episodes of intestinal obstruction with multiple small intestinal ulcers and strictures after other common causes have been ruled out.

    Through the European Research Initiative on chronic lymphocytic leukemia (CLL) (ERIC), we screened 3490 patients with CLL for mutations within the NOTCH1 (n=3334), SF3B1 (n=2322), TP53 (n=2309), MYD88 (n=1080) and BIRC3 (n=919) genes, mainly at diagnosis (75%) and before treatment (>90%). BIRC3 mutations (2.5%) were associated with unmutated IGHV genes (U-CLL), del(11q) and trisomy 12, whereas MYD88 mutations (2.2%) were exclusively found among M-CLL. NOTCH1, SF3B1 and TP53 exhibited variable frequencies and were mostly enriched within clinically aggressive cases. Interestingly, as the timespan between diagnosis and mutational screening increased, so too did the incidence of SF3B1 mutations; no such increase was observed for NOTCH1 mutations. Regarding the clinical impact, NOTCH1 mutations, SF3B1 mutations and TP53 aberrations (deletion/mutation, TP53ab) correlated with shorter time-to-first-treatment (P<0.0001) in 889 treatment-naive Binet stage A cases. In multivariate analysis (n=774), SF3B1 mutations and TP53ab along with del(11q) and U-CLL, but not NOTCH1 mutations, retained independent significance. Importantly, TP53ab and SF3B1 mutations had an adverse impact even in U-CLL. In conclusion, we support the clinical relevance of novel recurrent mutations in CLL, highlighting the adverse impact of SF3B1 and TP53 mutations, even independent of IGHV mutational status, thus underscoring the need for urgent standardization/harmonization of the detection methods.

    An adolescent with chronic recurrent multifocal osteomyelitis located to both iliac bones and an adult with pustulotic arthro-osteitis, involving the left iliac bone, an invertebral space, and the sternoclavicular, first sternocostal, manubriosternal and single peripheral joints are described. Their iliac bone changes were identical, except for the occurrence of bilateral changes in the adolescent, and ankylosis of the sacroiliac joint in the adult. It is suggested that chronic recurrent multifocal osteomyelitis and pustulotic arthro-osteitis may be related diseases with age-dependent differences.

    Understanding how persistent interpersonal difficulties distinctly affect the course of major depressive disorder (MDD) during emerging adulthood is critical, given that early experiences impact future coping resources and functioning. Research on stress and MDD has mostly concentrated on stressful life events, while chronic stress largely has not been explored. The present study examined interpersonal (intimate relationship, close friendships, social life, family relationships) and noninterpersonal (academic, work, financial, personal health, and family members' health) domains of chronic stress as time-varying predictors of depressive recurrence in emerging adults. Baseline assessments identified previously depressed emerging adults (N = 119), who subsequently completed 6-month, 12-month and 18-month follow-up interviews to determine chronic stress experiences and onset of new major depressive episodes. Survival analyses indicated that time-varying total chronic stress and chronic interpersonal stress predicted higher risk for depression recurrence; however, chronic noninterpersonal stress was not associated with recurrence. Intimate relationship stress, close friendship stress, family relationship stress, personal health, and family members' health independently predicted MDD recurrence, over and above well-established depression risk factors of dysfunctional cognitions and personality disorder symptoms. Evidence that interpersonal stress could have substantial impact on course of depression is consistent with theories of emerging adulthood, a time when young people are individuating from the family and experiencing significant social transition.

    Congenital hemangiopericytoma (HPC) is a rare mesenchymal tumor with less aggressive behavior and a more favorable prognosis than similar tumors in adults. Multifocal presentation is even less common than isolated HPC and hence its clinical and histologic recognition may be challenging. A newborn infant with multifocal congenital HPC causing severe deformity but with a favorable outcome after chemotherapy and surgical removal is reported.

    We present an unusual case of recurrent (chronic ambulatory peritoneal dialysis) CAPD-associated peritonitis caused by Neisseria cinerea. Using DNA restriction fragment length polymorphism (RFLP) analysis, we determined that the recurrent infection was caused by reinfection with a different N. cinerea strain rather than relapse with the index strain and that the probable origin of the reinfecting organism was the patient's upper respiratory tract.

  14. Chronic recurrent Gorham-Stout syndrome with cutaneous involvement

    Directory of Open Access Journals (Sweden)

    2010-09-01

    Full Text Available Type IV osteolysis or Gorham-Stout syndrome is a rare condition characterized by recurrent vascular tumors that disrupt normal anatomical architecture. Gorham-Stout syndrome is most commonly associated with the skeletal system with resulting replacement of bone with scar tissue following tumor regression. The loss of entire bones has given Gorham-Stout syndrome the moniker vanishing bone disease. Natural progression of Gorham-Stout syndrome is characterized by spontaneous disease resolution. However, rare variants of recurrent, progressive, and/or systemic disease have been reported. We present a patient with a history of recurrent Gorham-Stout disease refractory to all treatment options considered. In addition to skeletal disease, our patient had soft tissue and cutaneous involvement, thus reflecting the more aggressive disease variant. Previous surgical attempts to control disease had been ineffective and the patient was referred to us for radiation therapy. Treatment with external beam radiation therapy resulted in good local control and symptom palliation, but full disease resolution was never accomplished. In addition to presentation of this patient, a review of the literature on etiological hypotheses and past/future treatment options was conducted and is included.

    Full Text Available OBJECTIVE: This study was designed to investigate whether increased urothelial cell apoptosis and chronic inflammation might contribute to recurrent urinary tract infection (UTI in women. METHODS: The bladder biopsy specimens were collected from thirty women with recurrent UTI and ten controls. The bladder biopsies were performed at one to two months after UTI episode had been completely resolved and urine analysis and urine culture all showed negative. Immunofluorescence staining of the adhesive protein E-cadherin, mast cell and TUNEL were performed in all the bladder specimens. In addition, western blots were also performed to analyze the inflammatory proteins (phospho-p38, tryptase and apoptotic protein (Bax in the bladder mucosa specimens between patients with recurrent UTI and controls. RESULTS: Immunofluorescence staining showed significantly lower E-cadherin in the recurrent UTI bladder tissue compared with the controls (25.4±8.9 v 42.4±16.7, p<0.0001. The mast cell expression was significantly stronger in the recurrent UTI bladder tissue compared with the controls (2.5±1.8 v 1.3±1.2, p = 0.046. TUNEL staining revealed a significantly higher numbers of apoptotic cells in the recurrent UTI bladder tissue compared with the control bladder tissue (1.5±1.8 v 0.08±0.3, p<0.0001. Western blot analysis also showed that the expressions of tryptase and Bax increased in five recurrent UTI specimens compared with two normal control specimens. CONCLUSION: Chronic inflammation, urothelial cell apoptosis and impairment of barrier function of urothelial cells might contribute to recurrent UTI in women.

    Full Text Available Background. Major depression is often chronic or recurrent and is usually treated within primary care. Little is known about the associated morbidity and costs. Objectives. To determine socio-demographic characteristics of people with chronic or recurrent depression in primary care and associated morbidity, service use, and costs. Method. 558 participants were recruited from 42 GP practices in the UK. All participants had a history of chronic major depression, recurrent major depression, or dysthymia. Participants completed questionnaires including the BDI-II, Work and Social Adjustment Scale, Euroquol, and Client Service Receipt Inventory documenting use of primary care, mental health, and other services. Results. The sample was characterised by high levels of depression, functional impairment, and high service use and costs. The majority (74% had been treated with an anti-depressant, while few had seen a counsellor (15% or a psychologist (3% in the preceding three months. The group with chronic major depression was most depressed and impaired with highest service use, whilst those with dysthymia were least depressed, impaired, and costly to support but still had high morbidity and associated costs. Conclusion. This is a patient group with very significant morbidity and high costs. Effective interventions to reduce both are required.

    Full Text Available Introduction Cri du chat syndrome is a rare genetic disorder due to deletion of variable length of short arm of chromosome 5(5p. It mainly presents with typical cat like cry, facial dysmorphism, poor growth with feeding problems and severe cognitive, speech, and motor delays. Case Report We present here a one year old child who did not presented with typical features but presented with recurrent pneumonia with chronic stridor since early infancy. On evaluation we found short flabby epiglottis and we did karyotyping which showed 5P deletion syndrome. Conclusion Cri du chat syndrome can be presented with atypical features like chronic stridor and recurrent pneumonia without having typical cat like cry. Early diagnosis is necessary for proper counselling of parents and treatment of the patient.

A 26-year-old male patient, who was a hepatitis B virus carrier, was co-infected with Salmonella enterica serovar Paratyphi A and hepatitis A virus. The recurrence of the paratyphoid fever may be ascribed to the coexistence of hepatitis B, a course of ceftriaxone plus levofloxacin that was too short and the insensitivity of paratyphoid fever A to levofloxacin. We find that an adequate course and dose of ceftriaxone is a better strategy for treating paratyphoid fever. Furthermore, the co-infection of paratyphoid fever with hepatitis A may stimulate cellular immunity and break immunotolerance. Thus, the administration of the anti-viral agent entecavir may greatly improve the prognosis of this patient with chronic hepatitis B, and the episodes of paratyphoid fever and hepatitis A infection prompt the use of timely antiviral therapy.

    Chronic emotional stress is associated with increased cortisol release and metabolism disorders. However, few studies have evaluated the influence of chronic stress on calcium oxalate (CaOx) stone disease and its recurrence. A total of 128 patients were enrolled in this case-control study over a period of 20 months. All patients were CaOx stone formers with a recent stone episode (chronic stress were evaluated with self-reported validated questionnaires measuring stressful life events, perceived stress, anxiety, depression, burnout and satisfaction with life. An ad hoc self-reporting questionnaire was designed to evaluate stress-related specifically to stone episodes. Blood and urine samples were collected to determine cortisol levels and urinary composition. In addition, epidemiological data, socioeconomic information, diet and incidences of metabolic syndrome (MS) were reported. Overall, no significant differences were observed in the scores of cases and controls on any of the questionnaires dealing with stress. The number (p chronic stress, the number and intensity of stressful life events were higher in RS than in FS. These differences correlate with variations in blood and urinary levels and with metabolic disorders, indicating an association between chronic stress and risk of recurrent CaOx stone formation.

    The aim of this study was to determine the frequency of misdiagnosis of sinus headache in migraine and other primary headache types in the children and adolescents with chronic or recurrent headaches. Children with chronic or recurrent headaches (n = 310) were prospectively evaluated. Data collection for each patient included history of previously diagnosed sinusitis due to headache, and additional sinusitis complaints (such as fever, cough, nasal discharge, postnasal discharge) at the time of sinusitis diagnosis, and improvement of the headache following treatment of sinusitis. If sinus radiographs existed they were recorded. The study included 214 patients with complete data. One hundred and sixteen (54.2%) patients have been diagnosed as sinusitis previously and 25% of them had at least one additional complaint, while 75% of them had none. Sinusitis treatment had no effect on the headaches in 60.3% of the patients. Sinus graphy had been performed in 52.8%, and 50.4% of them were normal. The prevalence of sinus headache concomitant with primary headache, and only sinus headache was detected in 7 and 1%, respectively, in our study. Approximately 40% of the patients with migraine and 60% of the patients with tension-type headache had been misdiagnosed as "sinus headache". Children with chronic or recurrent headaches are frequently misdiagnosed as sinus headache and receive unnecessary sinusitis treatment and sinus graphy.

  11. Early severe inflammatory responses to uropathogenic E. coli predispose to chronic and recurrent urinary tract infection.

    Directory of Open Access Journals (Sweden)

    Thomas J Hannan

    Full Text Available Chronic infections are an increasing problem due to the aging population and the increase in antibiotic resistant organisms. Therefore, understanding the host-pathogen interactions that result in chronic infection is of great importance. Here, we investigate the molecular basis of chronic bacterial cystitis. We establish that introduction of uropathogenic E. coli (UPEC into the bladders of C3H mice results in two distinct disease outcomes: resolution of acute infection or development of chronic cystitis lasting months. The incidence of chronic cystitis is both host strain and infectious dose-dependent. Further, development of chronic cystitis is preceded by biomarkers of local and systemic acute inflammation at 24 hours post-infection, including severe pyuria and bladder inflammation with mucosal injury, and a distinct serum cytokine signature consisting of elevated IL-5, IL-6, G-CSF, and the IL-8 analog KC. Mice deficient in TLR4 signaling or lymphocytes lack these innate responses and are resistant, to varying degrees, to developing chronic cystitis. Treatment of C3H mice with the glucocorticoid anti-inflammatory drug dexamethasone prior to UPEC infection also suppresses the development of chronic cystitis. Finally, individuals with a history of chronic cystitis, lasting at least 14 days, are significantly more susceptible to redeveloping severe, chronic cystitis upon bacterial challenge. Thus, we have discovered that the development of chronic cystitis in C3H mice by UPEC is facilitated by severe acute inflammatory responses early in infection, which subsequently are predisposing to recurrent cystitis, an insidious problem in women. Overall, these results have significant implications for our understanding of how early host-pathogen interactions at the mucosal surface determines the fate of disease.

    2008-07-01

    Full Text Available Abstract Introduction Gastric volvulus is an uncommon clinical entity, first described by Berti in 1866. It is a rotation of all or part of the stomach through more than 180°. This rotation can occur on the longitudinal (organo-axial or transverse (mesentero-axial axis. This condition can lead to a closed-loop obstruction or strangulation. Traditional surgical therapy for gastric volvulus is based on an open approach. Here we report the case of a patient with chronic intermittent gastric volvulus who underwent a successful laparoscopic treatment. Case presentation A 34-year-old woman presented with multiple episodes of recurrent upper abdominal pain associated with retching and vomiting, treated unsuccessfully with intramuscular metoclopramide. Endoscopic examination of the upper digestive tract showed a suspected rotation of the stomach, and a chronic recurrent gastric volvulus was revealed by barium meal. The patient was operated on successfully, with an anterior laparoscopic gastropexy performed as the first surgical approach. Conclusion Experience with laparoscopic anterior gastropexy is limited only to a few described cases. Our patient was clinically and radiologically followed-up for 2 years with no evidence of recurrence, either radiological or symptomatic. Based on this result, laparoscopic gastropexy can be seen and considered as an initial 'gold standard' for the treatment of gastric volvulus.

    Hypogeusia, a condition with diminished sense of taste, is caused by several conditions, including zinc deficiency and as a side-effect of drugs, but is not common in neurological disorders. A 55-year-old Japanese man with a 30-year history of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) presented with hypogeusia during hospitalization for a recurrence of CIDP. The hypogeusia improved after treatment with high-dose intravenous methylprednisolone (HIMP). Two years later, hypogeusia developed again. A complete taste deficit was revealed by a filter paper test. Brain MRI showed enhancement of the bilateral facial nerve ganglia. Hypogeusia was partially ameliorated after extensive immunosuppressive therapy with repeated HIMP and plasma exchange. Improvement was more prominent in the area innervated by the chorda tympani nerve than that innervated by the glossopharyngeal nerve. To our knowledge, this is the first report of recurrent hypogeusia, which might be caused by cranial nerve injury associated with CIDP.

    Seventy-one patients from northern Sweden were diagnosed with chronic subdural haematomas (CSDH) and treated at the Department of Neurosurgery at Umeå University Hospital over 12 months. Fifty-four patients with CSDH had a history of head trauma (trauma group), while 17 patients had no previous head trauma (non-trauma group). In the non-trauma group 71% of patients were treated with anticoagulants or antiplatelet aggregation agents (AAA) compared to 18% in the trauma group. Considering only AAA, 59% of the non-trauma patients were treated with these drugs versus 17% of patients in the trauma group. The recurrence rate for all patients was 17%. These findings confirm that the use of anticoagulants and AAA is over-represented in patients with non-traumatic CSDH. In our study, recurrence was not associated with previous use of anticoagulants or AAA.

    Despite technological improvements in dialysis connectology and dialysis technique, peritonitis remains the most common and most significant complication of peritoneal dialysis (PD) in children. Most children undergoing chronic PD experience none or only one peritonitis episode, while others have multiple episodes or episodes secondary to unusual organisms. Knowledge of potential risk factors and likely patient outcome is imperative if treatment is to be optimized. In this review we will, in turn, describe episodes of peritonitis that are characterized as either relapsing, recurrent, repeat or zoonosis-related to highlight the clinical issues that are commonly encountered by clinicians treating these infections.

    2006-01-01

    Full Text Available Recurrent respiratory papillomatosis is a relatively uncommon disease that presents clinically with symptoms ranging from hoarseness to severe dyspnea. Human papilloma virus types 6 and 11 are important in the etiology of papillomas and are most probably transmitted from mother to child during birth. Although spontaneous remission is frequent, pulmonary spread and/or malignant transformation resulting in death has been reported. CO2 laser evaporation of papillomas and adjuvant drug therapy using lymphoblastoid interferon-alpha are the most common treatments. However, several other treatments have been tried, with varying success. In the present report, a case of laryngeal papillomatosis presenting with chronic stridor and delayed speech is described.

    We experienced two cases of recurrent poststernotomy mediastinitis with chronic mediastinal fistula. Both cases had already received muscle flaps for post operative mediastinitis. However, chronic mediastinal fistula appeared after nine months in the first case, and eleven months in the second case. We removed the infected tissue and the predgets, which were used on the ascending aorta. Then closed the wound by the muscle flap closure. The chronic fistula were closed, and the functional and cosmetic results were excellent.

    Full Text Available Objective. The purpose of this pilot study is to investigate the effectiveness of the percutaneous soft tissue release for the treatment of recurrent myofascial pain in the forearm due to recurrent lateral epicondylitis. Methods. Six patients with chronic recurrent pain in the forearm with myofascial trigger points (MTrPs due to chronic lateral epicondylitis were treated with percutaneous soft tissue release of Lin’s technique. Pain intensity (measured with a numerical pain rating scale, pressure pain threshold (measured with a pressure algometer, and grasping strength (measured with a hand dynamometer were assessed before, immediately after, and 3 months and 12 months after the treatment. Results. For every individual case, the pain intensity was significantly reduced (P<0.01 and the pressure pain threshold and the grasping strength were significantly increased (P<0.01 immediately after the treatment. This significant effectiveness lasts for at least one year. Conclusions. It is suggested that percutaneous soft tissue release can be used for treating chronic recurrent lateral epicondylitis to avoid recurrence, if other treatment, such as oral anti-inflammatory medicine, physical therapy, or local steroid injection, cannot control the recurrent pain.

    Finsterer, J; Mamoli, B

    1995-01-01

    Multifocal motor neuropathy, which mimics lower motor neuron disease, is a rare and curious demyelinating neuropathy characterised by slowly progressive, asymmetric limb weakness within the distribution of individual peripheral nerves, wasting, cramps, fasciculations and rare sensory involvement, but without upper motor neuron signs. The cardinal feature and primary pathophysiological basis for the weakness is the multifocal motor conduction block which remains stable for years at the same site and is confined to motor axons. It is defined as > 50% reduction in both the CMAP and the negative peak area on proximal stimulation, as compared with the distal stimulus response without any change in the negative peak duration. Nerves at the site of the conduction block show demyelination, endoneural edema, rudimentary onion bulbs and lymphocytic inflammation. Sensory nerves may show mild demyelination, axon loss and lymphocytic inflammation. The majority of patients shows elevated titers of anti-glycolipid antibodies, which may block the Na+ channels, produce demyelination or interfere with remyelination. However, their role in the pathogenesis of multifocal motor neuropathy remains uncertain. Multifocal motor neuropathy is regarded as the predominantly motor variant of chronic inflammatory demyelinating polyneuropathy and can be treated best with immunoglobulins and cyclophosphamide.

    We describe a renal transplant recipient with systemic lupus erythematosus (SLE) who showed continuous proteinuria and low complement levels without clinical evidence of active SLE. Her first renal allograft biopsy, performed nine yr and eight months after transplantation, revealed unusual histological change of glomeruli, and it initially led us to make a contradictory diagnosis based on light and electron microscopic examinations. Diffuse global double- or multi-contour glomerular basement membrane was caused by chronic endothelial injury owing to chronic rejection, and mesangial proliferation associated with mesangial electron-dense deposit was a histological change characteristic of recurrent lupus nephritis (RLN). Immunofluorescence study displayed weak mesangial staining of IgM and C1q. We concluded that this case presented overlapped chronic rejection and RLN. Because both transplant nephropathy and lupus nephritis present constellations of various histologies, it is difficult to diagnose their overlap. Complete morphologic studies with both immunofluorescence and electron microscopic evaluations in addition to microscopic examination should be performed to elucidate complex histological findings.

    Full Text Available OBJECTIVES: The onset of chronic subdural hematoma may be associated with direct or indirect minor injuries to the head or a poorly repaired vascular injury. Endothelial progenitor cells happen to be one of the key factors involved in hemostasis and vascular repair. This study was designed to observe the levels of endothelial progenitor cells, white blood cells, platelets, and other indicators in the peripheral blood of patients diagnosed with chronic subdural hematoma to determine the possible relationship between the endothelial progenitor cells and the occurrence, development, and outcomes of chronic subdural hematoma. METHOD: We enrolled 30 patients with diagnosed chronic subdural hematoma by computer tomography scanning and operating procedure at Tianjin Medical University General Hospital from July 2009 to July 2011. Meanwhile, we collected 30 cases of peripheral blood samples from healthy volunteers over the age of 50. Approximately 2 ml of blood was taken from veins of the elbow to test the peripheral blood routine and coagulation function. The content of endothelial progenitor cells in peripheral blood mononuclear cells was determined by flow cytometry. RESULTS: The level of endothelial progenitor cells in peripheral blood was significantly lower in preoperational patients with chronic subdural hematomas than in controls. There were no significant differences between the two groups regarding the blood routine and coagulation function. However, the levels of circulating endothelial progenitor cells were significantly different between the recurrent group and the non-recurrent group. CONCLUSIONS: The level of circulating endothelial progenitor cells in chronic subdural hematoma patients was significantly lower than the level in healthy controls. Meanwhile, the level of endothelial progenitor cells in recurrent patients was significantly lower than the level in patients without recurrence. Endothelial progenitor cells may be related to the

    Purpose: The nonthermal irreversible electroporation (NTIRE) is a novel potential ablation modality for renal masses. The aim of this study was the first evaluation of NTIRE's effects on the renal urine-collecting system using intravenous urography (IVU) and urinary cytology in addition to histology and magnetic resonance imaging (MRI). Methods: Eight percutaneous NTIRE ablations of the renal parenchyma, including the calyxes or pelvis, were performed in three male swine. MRI, IVU, histology, and urinary cytology follow-ups were performed within the first 28 days after treatment. Results: MRI and histological analysis demonstrated a localized necrosis 7 days and a localized scarification of the renal parenchyma with complete destruction 28 days after NTIRE. The urine-collecting system was preserved and showed urothelial regeneration. IVU and MRI showed an unaltered normal morphology of the renal calyxes, pelvis, and ureter. A new urinary cytology phenomenon featured a temporary degeneration by individual vacuolization of detached transitional epithelium cells within the first 3 days after NTIRE. Conclusions: This first urographical, urine-cytological, and MRI evaluation after porcine kidney NTIRE shows multifocal parenchyma destruction while protecting the involved urine-collecting system with regenerated urothelial tissue. NTIRE could be used as a targeted ablation method of centrally located renal masses.

    The better understanding of chronic and recurrent rhinosinusitis and the advance in endoscopic endonasal surgery have modified the radiological pre-operative investigation of this condition. The ethmoid labyrinth, not accessible to the endoscope, may be explored by axial and coronal high-resolution thin section (2 mm) CT. We have reviewed 100 CT scans with endoscopic correlation in order to assess the accuracy of this pre-operative method. This anatomical study reveals the presence and extent of parasinus diseases which are usually concentrated in the area of the ostiomeatal unit. The anatomic variations of the lateral nasal wall that have been reporded as predisposing to sinusitis and the morphologic variations altering the relationships of the ethmoid with the orbits and the brain were also studied. This pre-operative radiological assessment is currently necessary for functional and safe surgery. (orig.)

    Chronic lymphocytic leukaemia (CLL), the most frequent leukaemia in adults in Western countries, is a heterogeneous disease with variable clinical presentation and evolution1,2. Two major molecular subtypes can be distinguished, characterized respectively by a high or low number of somatic hypermutations in the variable region of immunoglobulin genes3,4. The molecular changes leading to the pathogenesis of the disease are still poorly understood. Here we performed whole-genome sequencing of four cases of CLL and identified 46 somatic mutations that potentially affect gene function. Further analysis of these mutations in 363 patients with CLL identified four genes that are recurrently mutated: notch 1 (NOTCH1), exportin 1 (XPO1), myeloid differentiation primary response gene 88 (MYD88) and kelch-like 6 (KLHL6). Mutations in MYD88 and KLHL6 are predominant in cases of CLL with mutated immunoglobulin genes, whereas NOTCH1 and XPO1 mutations are mainly detected in patients with unmutated immunoglobulins. The patterns of somatic mutation, supported by functional and clinical analyses, strongly indicate that the recurrent NOTCH1, MYD88 and XPO1 mutations are oncogenic changes that contribute to the clinical evolution of the disease. To our knowledge, this is the first comprehensive analysis of CLL combining whole-genome sequencing with clinical characteristics and clinical outcomes. It highlights the usefulness of this approach for the identification of clinically relevant mutations in cancer. PMID:21642962

    Equine recurrent uveitis (ERU), a chronic, recurrent inflammation primarily of the anterior uveal tract, is the most common cause of blindness in horses. Recently, T-lymphocytes have been found to be the most numerous cell type to infiltrate the anterior uveal of horses with ERU. In the present study, we characterized the T-lymphocyte population in the anterior uveal tract of eyes of horses with chronic ERU by evaluating the microscopic appearance (histopathologic features), the T-lymphocyte subsets, and the relative levels and amounts of T-lymphocyte cytokine mRNA in the anterior uvea. Seven inflamed eyes (from six horses with chronic ERU) and 5 normal eyes (from five horses with nonocular problems) were studied. After clinical examination, the eyes were removed, ocular fluids were aspirated, and anterior uveal tissues (iris and ciliary body) were processed for histologic and molecular (RNA isolation) analyses. Histologic examination by hematoxylin and eosin (H and E) staining and immunohistochemistry evaluating T-lymphocyte subsets (anti-CD4, CD8, CD5) were performed for each sample. RNA samples were analyzed for levels of messenger (m) RNA specific for interleukin (IL)-2, 4, and interferon-gamma (IFNgamma) by quantitative reverse transcriptase polymerase chain reaction (QRT-PCR). Eyes with ERU exhibited characteristic clinical signs, including corneal edema, aqueous flare, posterior synechia, corpora nigra degeneration, and cataract formation. Histologically, infiltration of the uveal tract with lymphocytes, plasma cells, and macrophages was most evident in the ciliary body and base of the iris. Loss of tissue structure (destruction) was most evident in the ciliary processes. Infiltrating lymphocytes were predominantly CD4+ T-cells (e.g. 48% CD4+ and 18% CD8+ in the ciliary body stroma), as determined by immunohistochemistry. Few inflammatory cells were observed in the normal eyes. The QRT-PCR results revealed increased transcription of IL-2 and IFNgamma and low

    Chronic granulomatous disease is a group of syndromes which share a defect in a component of the phagocyte NADPH-oxidase complex. Without this enzyme activity, phagocytic cells cannot produce superoxide, peroxide, and other potent microbicidal radicals, and are less able to kill ingested pathogens. The clinical picture is characterised by recurrent life-threatening bacterial and fungal infections and abnormal tissue granuloma formation. On the other hand, amyloidosis is a systemic disease with renal involvement occurring in the majority of cases. Recurrent amyloidosis is a rare but well documented event in renal transplant recipients. However, graft loss secondary to amyloidosis has been noted infrequently. In addition, de novo amyloidosis has not been previously associated with graft loss. We report here a renal transplant recipient with chronic granulomatous disease and history of recurrent urinary tract infections, who developed nephrotic syndrome and progressive renal insufficiency secondary to de novo AA amyloidosis leading to graft loss 66 months after transplantation.

    Bronchitis is a common health problem in children. Frequent bronchitis in infancy increases the risk of developing chronic respiratory diseases. The aim of the study was to assess the level of growth and the nutritional status in children and youths with special regard to the level of body fatness assessed by measuring skin-fold thickness. Relationships between somatic development, pulmonary function and the course of the disease were also explored. The study was carried out using anthropometric and spirometric measurements and also information on the severity and course of the disease in 141 children with chronic or recurrent bronchitis. All of the subjects were patients of the Pulmonary Medicine and Allergology Center in Karpacz, Poland. The mean body height did not differ significantly between the children examined and their healthy peers. However, the infection-prone children had excessive body fatness and muscle mass deficiency. The increased level of subcutaneous adipose tissue occurred especially in children with short duration of the disease, i.e. a maximum of 1 year. The functional lung parameters were generally normal. The presence of atopic diseases such as allergic rhinitis or atopic dermatitis did not impair the course of the children's somatic development. Also, long-term disease or the presence of additional allergic diseases did not impair lung function in the examined children. Taking appropriate preventive measures is recommended to achieve and maintain normal body weight in children who receive therapy due to bronchitis.

    Objective: To explore the clinical efficacy of Chinese and western integrative medicine (TCM-WM) in treating repeatedly recurrent chronic pyelonephritis (CPN) and its therapeutic mechanism. Methods: Ninety-one repeatedly recurrent CPN patients were randomly divided into 2 groups, the control group (45 cases) treated with sufficient amount of sensitive antibiotics and other WM, the treated group (46 cases) treated with above-mentioned WM complemented with TCM syndrome differentiation (SD). Results: In the treated group completely cured was 14 cases (30.4%), markedly effective 14 cases (30.4%), the total effective rate was 91.3%; while that of the control group was 4 (8.9%), 5 (11.1%), and 48.9% respectively, (P<0.05) and (P<0.01); the mean days of urinary bacteria and urinary routine negative conversion were in the treated group 19.6±12.6 days and 24.3±11.5 days, obviously shorter than those of the control group (35.6±14.6 days and 53.6±16.4 days), P<0.01; the various symptoms of the treated group improved or disappeared in a short time, while in the control group a few patients improved in a longer period (P<0.01); the various immune parameters improved in the treated group, while in the control group only IgA was elevated to some extent (P<0.05), in comparing these data, the difference was significant (P<0.01). Conclusion: The TCM-WM integrative treatment could obviously raise the clinical efficacy, accelerate the symptom improvement, and enhance the immune function.

Classification of COPD severity was based on guidelines of the Global Initiative for Chronic Obstructive Lung Disease (GOLD. Characteristics among the three subgroups were compared and recurrence-free survivals were analyzed.Results: A total of 172 patients were diagnosed with COPD (124 as GOLD-1, 46 as GOLD-2, and two as GOLD-3. The frequencies of recurrence were significantly higher in patients with higher COPD grades (P<0.001. Recurrence-free survival at 5 years was 78.1%, 70.4%, and 46.4% in non-COPD, mild COPD, and moderate/severe COPD groups, respectively (P<0.001. By univariate analysis, the age, sex, smoking history, COPD severity, tumor size, histology, and pathological stage were associated with recurrence-free survival. Multivariate analysis showed that older age, male, moderate/severe COPD, and advanced stage were independent risk factors associated with recurrence-free survival.Conclusion: NSCLC patients with COPD are at high risk for postoperative recurrence, and moderate/severe COPD is an independent unfavorable prognostic factor.

    We studied host factors that could predispose women to develop recurrent vulvovaginal candidiasis (RVVC), including glycemia, insulin resistance, chronic stress, antioxidant capacity, overall immune status, local inflammation and vaginal microbiota. The presence of yeasts in vaginal culture was screened in 277 women, with or without signs and symptoms of VVC and RVVC. The presence of an inflammatory process and microbiota were analyzed through vaginal bacterioscopy and cervical-vaginal cytology, respectively. Fasting-blood samples were collected by standard venipuncture for biochemical analyses. Flow cytometry was employed to obtain the T helper/T cytotoxic lymphocyte ratio, and insulin resistance was assessed by the HOMA index (HI). Yeasts were isolated from 71 (26%) women: 23 (32.4%) with a positive culture but without symptoms (COL), 22 (31%) in an acute episode (VVC), and 26 (36.6%) with RVVC. C. albicans was the main yeast isolated in all clinical profiles. The control group (negative culture) comprised 206 women. Diabetes mellitus and insulin resistance were more associated with the positive-culture groups (COL, VVC and RVVC) than with negative ones. The RVVC group showed lower mean levels of cortisol than the control group and lower antioxidant capacity than all other groups. The T Helper/T cytotoxic lymphocyte ratio was similar in all groups. The RVVC group showed a similar level of vaginal inflammation to the control group, and lower than in the COL and VVC groups. Only the CVV group showed a reduction in vaginal lactobacillus microbiota. Our data suggest that both chronic stress (decreased early-morning cortisol levels) and reduced antioxidant capacity can be host predisposing factors to RVVC. PMID:27415762

    Age related atrophy of the laryngeal muscles -mainly the thyroarytenoid muscle (TAM)- leads to a glottal gap and consequently to a hoarse and dysphonic voice that significantly affects quality of life. The aim of our study was to reverse this atrophy by inducing muscular hypertrophy by unilateral functional electrical stimulation (FES) of the recurrent laryngeal nerve (RLN) in a large animal model using aged sheep (n = 5). Suitable stimulation parameters were determined by fatiguing experiments of the thyroarytenoid muscle in an acute trial. For the chronic trial an electrode was placed around the right RLN and stimulation was delivered once daily for 29 days. We chose a very conservative stimulation pattern, total stimulation time was two minutes per day, or 0.14% of total time. Overall, the mean muscle fiber diameter of the stimulated right TAM was significantly larger than the non-stimulated left TAM (30μm±1.1μm vs. 28μm±1.1 μm, p<0.001). There was no significant shift in fiber type distribution as judged by immunohistochemistry. The changes of fiber diameter could not be observed in the posterior cricoarytenoid muscle (PCAM). FES is a possible new treatment option for reversing the effects of age related laryngeal muscle atrophy. PMID:27893858

    Several reports have described an apparently uncommon clinicopathological disorder that is characterized by multifocal stenosing small-intestinal ulceration. Compared to Crohn's disease, the ulcers are not transmural and typically remain shallow, and involve only the mucosa and submucosa. The disorder seems to be localized in the jejunum and proximal ileum only, and not the distal ileum or colon. Only nonspecific inflammatory changes are present without giant cells or other typical features of granulomatous inflammation. Most patients present clinically with recurrent obstructive events that usually respond to steroids, surgical resection, or both. With the development of newer imaging modalities to visualize the small-intestinal mucosa, such as double-balloon enteroscopy, improved understanding of the long-term natural history of this apparently distinctive disorder should emerge.

    Full Text Available This report describes the modification of hemiplegic shoulder pain and walking velocity through injections of Xeomin®, a new botulinum neurotoxin type A formulation, in a 67-year-old woman with chronic residual left hemiparesis and hemiparetic gait attributable to stroke. Clinical evaluation included upper and lower limb spasticity, upper and lower limb pain, trunk control, upper and lower limb motricity index, visual gait analysis, and gait velocity. Assessments were performed before, 1 week after, and 1 month after treatment. Improvement was observed in all clinical parameters assessed. Amelioration of spasticity of the upper and lower limbs and shoulder pain was observed after 1 month. Trunk postural attitude and paraxial muscle recruitment recovered. No adverse events were observed and the patient shows significant improvement of functional impairment derived from chronic spasticity after treatment with Xeomin®. We also provide a simple and useful protocol for clinical evaluation of the treatment.

    Full Text Available Abstract Background Recurrent airway obstruction (RAO in horses is a naturally occurring dust-induced disease mainly characterized by bronchiolitis which shows histological and pathophysiological similarities to human chronic obstructive pulmonary disease (COPD. In human COPD previous investigations indicated an association with Chlamydophila psittaci infection. The present study was designed (1 to clarify a possible role of this infectious agent in RAO and (2 to investigate the suitability of this equine disorder as a model for human COPD. Methods Clinico-pathological parameters of a total of 45 horses (25 horses with clinical signs of RAO and 20 clinically healthy controls were compared to histological findings in lung tissue samples and infection by Chlamydiaceae using light microscopy, immunohistochemistry, and PCR. Results Horses with clinical signs of RAO vs. controls revealed more inflammatory changes in histology (p = 0.01, and a higher detection rate of Chlamydia psittaci antigens in all cells (p OmpA sequencing identified Chlamydophila psittaci (n = 9 and Chlamydophila abortus (n = 13 in both groups with no significant differences. Within the group of clinically healthy horses subgroups with no changes (n = 15 and slight inflammation of the small airways (n = 5 were identified. Also in the group of animals with RAO subgroups with slight (n = 16 and severe (n = 9 bronchiolitis could be formed. These four subgroups can be separated in parts by the number of cells positive for Chlamydia psittaci antigens. Conclusion Chlamydophila psittaci or abortus were present in the lung of both clinically healthy horses and those with RAO. Immunohistochemistry revealed acute chlamydial infections with inflammation in RAO horses, whereas in clinically healthy animals mostly persistent chlamydial infection and no inflammatory reactions were seen. Stable dust as the known fundamental abiotic factor in RAO is comparable to smoking in human disease. These

    To identify genomic alterations in chronic lymphocytic leukemia (CLL), we performed single-nucleotide polymorphism-array analysis using Affymetrix Version 6.0 on 353 samples from untreated patients entered in the CLL8 treatment trial. Based on paired-sample analysis (n = 144), a mean of 1.8 copy number alterations per patient were identified; approximately 60% of patients carried no copy number alterations other than those detected by fluorescence in situ hybridization analysis. Copy-neutral loss-of-heterozygosity was detected in 6% of CLL patients and was found most frequently on 13q, 17p, and 11q. Minimally deleted regions were refined on 13q14 (deleted in 61% of patients) to the DLEU1 and DLEU2 genes, on 11q22.3 (27% of patients) to ATM, on 2p16.1-2p15 (gained in 7% of patients) to a 1.9-Mb fragment containing 9 genes, and on 8q24.21 (5% of patients) to a segment 486 kb proximal to the MYC locus. 13q deletions exhibited proximal and distal breakpoint cluster regions. Among the most common novel lesions were deletions at 15q15.1 (4% of patients), with the smallest deletion (70.48 kb) found in the MGA locus. Sequence analysis of MGA in 59 samples revealed a truncating mutation in one CLL patient lacking a 15q deletion. MNT at 17p13.3, which in addition to MGA and MYC encodes for the network of MAX-interacting proteins, was also deleted recurrently.

  7. Secondary prevention of recurrence by interferon therapy after ablation therapy for hepatocellular carcinoma in chronic hepatitis C patients

    Chronic hepatitis C is a leading cause of hepatocellular carcinoma (HCC) worldwide. Interferon (IFN) ther-apy decreases the incidence of HCC in patients with chronic hepatitis C. Prevention of chronic-hepatitis-C-related HCC is one of the most important issues in current hepatology. We have previously reported that male gender and high titer of hepatitis C virus (HCV) RNA are predictive factors for the development of HCC in HCV-related cirrhosis. Clinical efforts at eradicat-ing or reducing the viral load may reduce the risk for HCC. Furthermore, because HCC often recurs after ablation therapy, we performed a trial of IFN in pa-tients with chronic liver disease caused by HCV to see whether IFN therapy decreases recurrence after abla-tion therapy of HCV-related HCC. By using IFN therapy as a secondary prevention, patients with HCC who had received complete tumor ablation showed better sur-vival, primarily as a result of the preservation of liver function and also probably prevention of recurrence. Postoperative IFN therapy appears to decrease recur-fence after ablation therapy such as radiofrequency ablation (RFA) therapy of HCV-related HCC. We believe that there is a survival benefit in secondary prevention using IFN therapy. However, a controlled study is es-sential to obtain conclusive evidence of the efficacy of this strategy.

    Full Text Available Chronic inflammatory demyelinating polyneuropathy is a demyelinating polyneuropathy characterized by distal/proximal weakness, which shows gradual progression over a period of 8 weeks or longer. Guillan-Barre Syndrome is a condition characterized by acute monophasic paralysis typically following an infectious assault, and it usually peaks in severity over 3-4 weeks at most. Although rare, there are acute-onset chronic inflammatory demyelinating polyneuropathy cases that show progression over a period shorter than 4 weeks, as is the case in Guillan-Barre Syndrome .This report discusses a case of chronic inflammatory demyelinating polyneuropathy in a HBsAg-positive patient, which started as Guillan-Barre Syndrome but showed 3 recurrences within 6 months, each with rapidly progressing quadriplegia, respiratory arrest, and elevated liver enzymes and HBV DNA.

    Gemma D Kok

    Full Text Available OBJECTIVE: To perform a systematic review, and if possible a meta-analysis, to establish whether depressed patients with co-morbid chronic somatic illnesses are a high risk "double trouble" group for depressive recurrence. METHOD: The databases PubMed, EMbase and PsycINFO were systematically searched until the 4(th of December 2012 by using MeSH and free text terms. Additionally, reference lists of retrieved publications and treatment guidelines were reviewed, and experts were consulted. Inclusion criteria were: depression had to be measured at least twice during the study with qualified instruments and the chronic somatic illness had to be assessed by self-report or by a medical professional. Information on depressive recurrence was extracted and additionally risk ratios of recurrence were calculated. RESULTS: The search generated four articles that fulfilled our inclusion criteria. These studies showed no differences in recurrence over one- two- three- and 6.5 years of follow-up for a total of 2010 depressed patients of which 694 patients with a co-morbid chronic somatic illness versus 1316 patients without (Study 1: RR = 0.49, 95% CI, 0.17-1.41 at one year follow-up and RR = 1.37, 95% CI, 0.78-2.41 at two year follow-up; Study 2: RR = 0.94, 95% CI, 0.65-1.36 at two year follow-up; Study 3: RR = 1.15, 95% CI, 0.40-3.27 at one year follow-up; RR = 1.07, 95% CI, 0.48-2.42 at two year follow-up and RR = 0.99, 95% CI,0.55-1.77 at 6.5 years follow-up; Study 4: RR = 1.16, 95% CI, 0.86-1.57 at three year follow-up. CONCLUSION: We found no association between a heightened risk for depressive recurrence and co-morbid chronic somatic illnesses. There is a need for more longitudinal studies to justify the current specific treatment advice such as long-term pharmacological maintenance treatment for this presumed "double trouble" group.

    OBJECTIVE. Not much is known about surgical management of patients with chronic subdural haematoma (CSDH) treated with antiplatelet or anticoagulant therapy. The aims of this study were to review the surgical outcomes of patients with CSDH and assess the risks of antiplatelet in their surgical management. METHODS. We retrospectively analysed 448 consecutive patients with CSDH treated by one burr hole surgery at our institution. Among them, 58 patients had been on antiplatelet therapy. We discontinued the antiplatelet agents before surgery for all 58 patients. For 51 of these 58 patients (87.9%), early surgery was performed within 0-2 days from admission. We analysed the association between recurrence and patient characteristics, including history of antiplatelet or anticoagulant therapy; age (antiplatelet or anticoagulant therapy did not significantly increase recurrence risk. Also, the recurrence rate from early surgery (0-2 days from drug cessation) for patients on antiplatelet therapy was not significantly higher than that from elective surgery (5 days or more after drug cessation). However, multivariate analysis revealed that previous history of cerebral infarction was an independent risk factor for CSDH recurrence. CONCLUSIOns. Our overall data support the safety of early surgery for patients on the preoperative antiplatelet therapy without drug cessation or platelet infusion. Patients with a previous history of infarction may need to be closely followed regardless of antiplatelet or anticoagulant therapy.

    Full Text Available Risk factors associated with chronic otitis media (COM and recurrent otitis media (ROM have been investigated in previous studies. The objective of this study was to integrate the findings and determine the possible risk factors for COM/ROM based on our meta-analysis. A comprehensive search of electronic bibliographic databases (PubMed, Embase, CNKI and Wanfang database from 1964 to Dec 2012, as well as a manual search of references of articles, was performed. A total of 2971 articles were searched, and 198 full-text articles were assessed for eligibility; 24 studies were eligible for this meta-analysis. Regarding risk factors for COM/ROM, there were two to nine different studies from which the odds ratios (ORs could be pooled. The presence of allergy or atopy increased the risk of COM/ROM (OR, 1.36; 95% CI, 1.13-1.64; P = 0.001. An upper respiratory tract infection (URTI significantly increased the risk of COM/ROM (OR, 6.59; 95% CI, 3.13-13.89; P<0.00001. Snoring appeared to be a significant risk factor for COM/ROM (OR, 1.96; 95% CI, 1.78-2.16; P<0.00001. A patient history of acute otitis media (AOM/ROM increased the risk of COM/ROM (OR, 11.13; 95% CI, 1.06-116.44; P = 0.04. Passive smoke significantly increased the risk of COM/ROM (OR, 1.39; 95% CI, 1.02-1.89 P = 0.04. Low social status appeared to be a risk factor for COM/ROM (OR, 3.82; 95% CI, 1.11-13.15; P = 0.03. Our meta-analysis identified reliable conclusions that allergy/atopy, URTI, snoring, previous history of AOM/ROM, Second-hand smoke and low social status are important risk factors for COM/ROM. Other unidentified risk factors need to be identified in further studies with critical criteria.

    Chronic and recurrent respiratory tract disorders are a frequent problem in general practice. The purpose of the study was to investigate the role of hypersensitivity to house dust mites in respiratory tract diseases in general practice patients. We tried to assess the influence of determined risk factors exposure on development of respiratory tract allergy. Patients from family practitioners surgeries with chronic or recurrent respiratory tract symptoms who had no diagnosis of allergy were recruited to the study (n = 89). All patients responded to a questionnaire focused on history of symptoms, atopic conditions in family and exposure to determined environmental factors like dwelling conditions, obstetrician history, diet in the first year of life. All patients underwent skin prick test with common inhalant allergens. Families of the patients were asked to participate in the study. Families who agreed to take part also responded to the questionnaire and underwent skin tests. In patients and their families blood samples were taken to determine total IgE and specific IgE antibodies to mites allergens. Dust samples were collected by vacuuming of patients' bedroom carpets and mattresses to determine house dust mites allergens concentration. Data on 30 complete patients family sets of their brotherhood, mother and father were collected. Total and specific serum IgE antibodies were determined by disc enzyme-immunoassay (Analco). Mites allergens concentration in dust was measured by simple Acarex strip test (Nexter). The results of the assays (positive skin tests and/or elevated levels of specific IgE) showed allergy to house dust mites in 24 of 89 study patients from general practitioners surgeries (27%). The prevalence of chronic rhinitis, recurrent bronchitis, chronic or recurrent cough, wheezing, dyspnoea was higher in allergic than in nonallergic subjects. Patients with the diagnosis of allergy to house dust mites had usually worse dwelling conditions. Especially

    47 patients with chronically recurrent calcium lithiasis (with between 3 and over 100 stone episodes) and an average age of 43.2 years have been examined. The Ca absorption lay between 42.7% and 90.0% of the dose, the average was 59.3% with a standard deviation of +- 12.9. This is higher than in persons with healthy kidneys. The Ca absorption is significantly lower in patients with renal insufficiency. Studies on Ca kinetics revealed turnover rates and pool sizes within the normal range.

    Autoimmune manifestations are common both in patients chronically infected by hepatitis C virus, and in patients transplanted for non-autoimmune diseases. A correlation between interferon based treatment and autoimmune diseases or the development of autoantibodies is well established in non-transplanted patients, but few data are available about transplanted patients. It is unclear whether interferon may increase the incidence of acute cellular rejection and there are few reports on the development of atypical autoimmune manifestations during post-liver transplantation interferon or pegylated interferon treatment. We describe a case of systemic lupus erythematosus following treatment with pegylated interferon alfa-2b in a transplanted patient with recurrence of chronic hepatitis C. Our experience suggest that pegylated interferon may induce autoimmune diseases in the immunosuppressed host, different from acute cellular rejection and call for a great attention to possible autoimmune disorders development during interferon based treatments in liver transplanted patients.

    Objective  To describe a surgical technique and to report using a retrospective study the efficacy of peritoneal shunts for the treatment of recurrent/chronic subdural hematoma (CSDH). We describe the considerations, complications, and outcomes related to this technique. Methods  In a retrospective cohort study, 125 charts with a diagnosis of subacute/chronic subdural hematoma were assigned for evaluation. Of the charts reviewed, 18 charts were found from subjects with a diagnosis of recurrent sub-acute or chronic subdural hematoma. All patients had undergone initial surgical treatment of their condition followed by peritoneal shunt placement to help alleviate intracranial pressure. Factors including the age, size of subdural hematoma, number of previous events, BMI, complications, survival, and clinical course were analyzed. Results  After subdural peritoneal shunt placement all patients had full neurological recovery with no complaints of headaches, lethargy, weakness, confusion or seizures. None of the cases had new subdural hematoma episodes after placement for a minimum of a two-year period (mean 26.1 months) (range 24.3-48.6 months). No postoperative complications were reported. The rates of postoperative hemorrhage, infection, distal catheter revision, and perioperative seizures was found to be zero percent. Shunt drainage was successful in all cases, draining 85% of the blood in the first 48 hours. There was no significant relationship between complications and the use of anticoagulants four weeks after surgery. Conclusions Peritoneal shunts, though rarely used, are a viable option in the treatment of sub-acute/chronic subdural hematomas. When pursuing this treatment, this technique is recommended to mitigate the risks of repeat surgical intervention and lessen perioperative time in high-risk patients. PMID:27335718

    Activated alpha-smooth muscle actin (alpha-SMA)-positive hepatic stellate cells (HSCs) are pericytes responsible for fibrosis in chronic liver injury. The glial fibrillary acidic protein (GFAP), commonly expressed by astrocytes in the central nervous system, is expressed in vivo in the liver in a subpopulation of quiescent stellate cells. In the rat, increased GFAP expression in the acute response to injury and down-regulation in the chronic response have been observed, whereas reports concerning GFAP expression in human liver are still conflicting. We investigated the utility of GFAP compared to alpha-SMA as an immunohistochemical marker of early activated HSCs in chronic and posttransplant recurrent hepatitis C and correlated GFAP expression with vascular remodeling and fibrosis progression. With immunohistochemistry and a semiquantitative scoring system, the expression of GFAP and alpha-SMA in HSCs and the microvessel density were analyzed in biopsies from normal livers obtained from cadaveric donors [donor liver (DL); n = 21] and from livers from posttransplant hepatitis C virus recurrent hepatitis (HCV-PTR) patients (n = 19), hepatitis C virus chronic hepatitis (HCV-CH) patients, (n = 12), and hepatitis C virus cirrhosis (HCV-C) patients (n = 16). The percentage of alpha-SMA-positive HSCs was significantly higher in the HCV-PTR, HCV-CH, and HCV-C groups compared to the DL group (P HCV-PTR group compared to the DL, HCV-C (P HCV-CH (P HCV-CH group compared to the DL group (P HCV-PTR group, the percentage of GFAP-positive HSCs correlated with fibrosis progression (P HCV-CH and seems to predict fibrosis progression in HCV-PTR.

    Full Text Available Here we have identified HIV-1 B clade Envelope (Env amino acid signatures from early in infection that may be favored at transmission, as well as patterns of recurrent mutation in chronic infection that may reflect common pathways of immune evasion. To accomplish this, we compared thousands of sequences derived by single genome amplification from several hundred individuals that were sampled either early in infection or were chronically infected. Samples were divided at the outset into hypothesis-forming and validation sets, and we used phylogenetically corrected statistical strategies to identify signatures, systematically scanning all of Env. Signatures included single amino acids, glycosylation motifs, and multi-site patterns based on functional or structural groupings of amino acids. We identified signatures near the CCR5 co-receptor-binding region, near the CD4 binding site, and in the signal peptide and cytoplasmic domain, which may influence Env expression and processing. Two signatures patterns associated with transmission were particularly interesting. The first was the most statistically robust signature, located in position 12 in the signal peptide. The second was the loss of an N-linked glycosylation site at positions 413-415; the presence of this site has been recently found to be associated with escape from potent and broad neutralizing antibodies, consistent with enabling a common pathway for immune escape during chronic infection. Its recurrent loss in early infection suggests it may impact fitness at the time of transmission or during early viral expansion. The signature patterns we identified implicate Env expression levels in selection at viral transmission or in early expansion, and suggest that immune evasion patterns that recur in many individuals during chronic infection when antibodies are present can be selected against when the infection is being established prior to the adaptive immune response.

    Full Text Available Gastroesophageal reflux (GER disorder was studied in children and adolescents with chronic and/or recurrent rhinosinusitis not associated with bronchial asthma. Ten children with a clinical and radiological diagnosis of chronic and/or recurrent rhinosinusitis, consecutively attended at the Pediatric Otolaryngology Outpatient Clinic, Federal University of São Paulo, were evaluated. Prolonged esophageal pH monitoring was used to investigate GER disorder. The mean age of the ten patients evaluated (eight males was 7.4 ± 2.4 years. Two patients presented vomiting as a clinical manifestation and one patient presented retrosternal pain with a burning sensation. Twenty-four-hour esophageal pH monitoring was performed using the Sandhill apparatus. An antimony probe electrode was placed in the lower third of the esophagus, confirmed by fluoroscopy and later by a chest X-ray. The parameters analyzed by esophageal pH monitoring included: total percent time of the presence of acid esophageal pH, i.e., pH below 4 (<4.2%; total number of acid episodes (<50 episodes; number of reflux episodes longer than 5 min (3 or less, and duration of the longest reflux episode (<9.2 min. One patient (1/10, 10% presented a 24-h esophageal pH profile compatible with GER disorder. This data suggest that an association between chronic rhinosinusitis not associated with bronchial asthma and GER disorder may exist in children and adolescents, especially in those with compatible GER disorder symptoms. In these cases, 24-h esophageal pH monitoring should be performed before indicating surgery, since the present data suggest that 10% of chronic rhinosinusitis surgeries can be eliminated.

    Full Text Available Allergic contact dermatitis is very common and may be complicated by secondary infections. Chronic lymphoedema is a potentially debilitating condition, which may occur due to secondary infections or the dermatitis itself. The problem of chronic lymphoedema following allergic contact dermatitis has been infrequently reported. We report a case of a 47-year-old woman with severe allergic contact dermatitis complicated by chronic, intractable lymphoedema of the hands and forearms. This case report reminds us that allergic hand dermatitis may be complicated by a chronic and debilitating state of lymphoedema. Also, it underlines the importance of fast and adequate treatment of both the dermatitis and the secondary infections.

    Full Text Available Chronic nonbacterial osteomyelitis (CNO with its most severe form chronic recurrent multifocal osteomyelitis (CRMO is a non-bacterial osteitis of yet unknown origin. Secondary to the absence of both high-titer autoantibodies and autoreactive T lymphocytes, and the association with other autoimmune diseases, it was recently reclassified as an autoinflammatory disorder of the musculoskeletal system. Since its etiology is largely unknown, the diagnosis is based on clinical criteria, and treatment is empiric and not always successful. In this paper, we summarize recent advances in the understanding of possible etiopathogenetic mechanisms in CNO.

    Full Text Available Background: This study was done to evaluate the effect of itraconazole on clinical symptoms and radiologic findings in patients with chronic rhinosinusitis and nasal polyposis after surgery. Materials and Methods: In a clinical trial which was conducted in Alzahra and Kashani hospitals, from November 2011 to December 2012, 22 patients with recurrent postsurgical chronic sinusitis and polyposis entered the study. At the start of the study demographic data, subjective clinical symptoms (severity of rhinorrhea, nasal obstruction, hyposmia, and dyspnea, quality of life (QoL by sinonasal outcome test-20 (SNOT-20, serum immunoglobulin E (IgE, and score of computed tomography (CT scan (by Lund-Mackay were recorded. Itraconazole (100 mg, twice per day prescribed for 3 months and patients were followed in the 1 st , 3 rd , and 6 th months. Liver enzyme tests and side effects were evaluated monthly. Results: Severity of rhinorrhea, nasal obstruction, hyposmia, dyspnea, and QoL (by SNOT-20 improved during 3 months of treatment. Serum IgE was 265 (±277 at the start of the study, and decrease to 193 (±183 after 3 month. After 3 month, Lund-Mackay score of CT scan lowered from 19 (±4 to 15 (±6 (P < 0.05. At the 6 th month, severity of clinical symptoms except dyspnea and QoL were better than first evaluation. Conclusion: This study showed the beneficial effect of 3-month itraconazole treatment on clinical symptoms and radiologic findings and QoL in patients with recurrent postsurgical chronic rhinosinusitis and nasal polyposis.

  3. Persistent and Recurrent Bacterial Bronchitis—A Paradigm Shift in Our Understanding of Chronic Respiratory Disease

    2017-01-01

    The recent recognition that the conducting airways are not “sterile” and that they have their own dynamic microbiome, together with the rapid advances in our understanding of microbial biofilms and their roles in the causation of respiratory diseases (such as chronic bronchitis, sinusitis, and chronic otitis media), permit us to update the “vicious circle” hypothesis of the causation of bronchiectasis. This proposes that chronic inflammation driven by persistent bacterial bronchitis (PBB) causes damage to both the epithelium, resulting in impaired mucociliary clearance, and to the airway wall, which eventually manifests as bronchiectasis. The link between a “chronic bronchitis” and a persistence of bacterial pathogens, such as non-typable Haemophilus influenzae, was first made more than 100 years ago, and its probable role in the causation of bronchiectasis was proposed soon afterward. The recognition that the “usual suspects” are adept at forming biofilms and hence are able to persist and dominate the normal dynamically changing “healthy microbiome” of the conducting airways provides an explanation for the chronic colonization of the bronchi and for the associated chronic neutrophil-dominated inflammation characteristic of a PBB. Understanding the complex interaction between the host and the microbial communities of the conducting airways in health and disease will be a key component in optimizing pulmonary health in the future.

    Most patients with IgA and/or IgG subclass deficiency are asymptomatic but some may suffer from frequent mainly respiratory infections. The aim of our study was to determine the frequency of IgA and/or IgG subclass deficiencies and the rate of chronic pulmonary damage secondary to recurrent pulmonary infections in these children. Serum IgA and IgG subclass levels were measured in 225 children aged 6 months to 6 years with recurrent sinopulmonary infections (44 with recurrent upper respiratory tract infections, 100 with recurrent pulmonary infections and 81 with recurrent bronchiolitis). In order to determine chronic pulmonary damage due to recurrent infections in patients with recurrent pulmonary infections CT scans of thorax were also obtained. The overall frequency of antibody defects was found to be 19.1%. IgA deficiency was observed in 9.3%, IgG subclass deficiency in 8.4% and IgA + IgG subclass deficiency in 1.4%. The prevalance of IgA and/or IgG subclass deficiency was 25% in patients with recurrent upper respiratory tract infections, 22% in patients with recurrent pulmonary infections and 12.3% in patients with recurrent bronchiolitis (p>0.05). Chronic pulmonary damage in lungs was determined radiologically in 17 of 100 cases with recurrent pulmonary infection. In IgG subclass deficiencies sequel changes, although not statistically significant, were observed five times more frequently than that of IgA deficiencies. CT scans revealed pulmonary sequels in 5 of the 22 (22.7%) patients with recurrent pulmonary infections and immunodeficiency (bronchiectasis in 2 patients with IgG3 deficiency, fibrotic changes in one with IgA deficiency and in one with IgG3 deficiency, bronchiolitis obliterans in one with IgG2 + IgG3 deficiency). On the other hand, pulmonary sequels were observed in 12 patients (15.4%) with normal immunoglobulin levels. Eight of them were bronchiolitis obliterans, 2 of them were atelectasia and 1 of them was bronchiectasia. We therefore suggest

    Multifocal motor neuropathy is characterized by a progressive asymetrical weakness, predominantly affecting the upper limbs with persistent conduction blocks on motor but not sensory nerves. Treatment woth prednisone and plasma exchanges have failed to demonstrate any positive effects. Some improvements have been reported with cyclophosphamide. Mainly immunoglobulin therapy has been evaluated with a beneficial response in almost 70% of the cases. These benefits obtained over periods of less than six months have recently been confirmed by a long-term evaluation of 18 patients treated by repeated infusions.

    A 29-year-old woman with a 4-year history of multifocal fibrosclerosis showed unique neurologic complications. Episcleritis, orbital pseudotumor, and eosinophilic phlegmon preceded intracranial inflammatory pachymeningitis. The pachymeningitis was associated with disturbance of the visual field, incomplete Gerstmann's syndrome, and pseudotumor cerebri. T2-weighted magnetic resonance images revealed a high signal intensity lesion in the left temporal and occipital lobes, and gadolinium-enhanced T1-weighted images revealed the enhancement of the thickened left tentorial leaf. The laboratory data suggested that the etiology might be autoimmunological. The disease and MRI abnormalities improved following administration of corticosteroids.

  7. Recurrent Chronic Ambulatory Peritoneal Dialysis-Associated Infection due to Rothia dentocariosa

    2004-01-01

    Full Text Available Rothia dentocariosa is a commensal organism of the human oropharynx. Clinical infection due to this organism is rare. A case of recurrent peritoneal dialysis-related peritonitis caused by R dentocariosa and a review of the literature is reported. Isolation of R dentocariosa from dialysate fluid should not be dismissed as a contaminant. Although there are no interpretive criteria for antimicrobial susceptibility testing, R dentocariosa appears to be susceptible to a variety of antibiotics including beta-lactams, vancomycin and aminoglycosides. Optimal therapy of peritoneal dialysis peritonitis caused by this organism may also require removal of the catheter.

    Array-based comparative genomic hybridization (arrayCGH) studies in chronic lymphocytic leukemia (CLL) have revealed novel recurrent chromosomal imbalances, such as a gain of chromosome 2p. However, a detailed cytogenetic analysis of the 2p gain region has not been elucidated. Here, we present cytogenetic and molecular cytogenetic analysis of 16 such cases selected from a group of 200 patients with CLL based on CGH and/or arrayCGH data. We revealed significant heterogeneity of the region of gain on 2p in CLL, including a new recurrent aberration: the dicentric chromosome, dic(2;18). In our cases, the region of gain involved three genes (MYCN, REL, and ALK) and was associated with an unmutated IgVH status in 14 out of 16 cases. We consider this aberration clinically important in CLL and suggest that an examination of the gene(s) located in region of gain should be included in the routine fluorescence in situ hybridization screening method used for patients with CLL.

    2007-01-01

    Objective: To observe the effect of Yishen Capsule (益肾胶囊, YSC) on preventing the recurrence of chronic glomerulonephritis (CGN) and to explore its mechanism preliminarily. Methods:CGN patients were assigned to the treated group (61 cases) and the control group (48 cases) and all of them were orally administered with 4 mg of Perindopril twice a day, but 3 capsules of YSC, thrice a day,were given additionally to patients in the treated group. The therapeutic course for both groups was 18 months. The recurrence rate of CGN at the 6th, 12th, and 18th month in the two groups was observed and compared, and the changes of 24-h urinary protein quantity and T-lymphocyte subsets before and after treatment were observed as well. Results: (1) Comparison of recurrence rate between the two groups showed insignificant difference at the 6th month, but it did show significant difference at the 12th and the 18th month, which was significantly decreased in the treated group than in the control group (P<0.05, P<0.01); (2) The 24-h urinary protein quantity at the 18th month decreased significantly in both groups (P<0.05, P<0.01), but in the treated group was more significant (P<0.01); (3) T-lymphocyte subsets showed no obvious change in the control group after treatment (P>0.05), while in the treated group, it showed significant increase in CD3, CD4 and CD4/CD8 (P<0.05 or P<0.01) and significant decrease in CD8 (P<0.05), and also the difference after treatment in T-lymphocyte subsets between the two groups was significant (P<0.05 or P<0.01). Conclusion: YSC has marked effects in reducing the recurrence of CGN and in decreasing urinary protein, and its mechanism might be related with its function in regulating the ratio of T-lymphocyte subsets to enhance the immunity of patients.

    Toxocariasis is a worldwide human helminthiasis, especially seen in temperate and tropical climate regions around the world. The diagnosis of this disease is performed on the basis of clinical symptoms and laboratory findings. Albendazole is one of the treatment choices for toxocariasis, with a currently recommended regimen of 10 mg/kg/day in two doses (400 mg twice daily) for 5 days. However, there is no precise consensus about the duration of the treatment. In this article, we report a case of toxocariasis; the patient visited our infectious disease polyclinic with complaints of long-term itching and urticarial skin lesions that were resistant to routine treatment and that recurred. Then, recurrent disease was resolved and skin lesions were diminished after prolonged albendazole therapy.

    Parathyroidectomy (PTX), either subtotal or total with forearm autografting, is a well-established treatment for refractory renal hyperparathyroidism (RHPT). However, 20-30% of patients develop persistent or recurrent disease. Obtaining accurate localization before reoperation is difficult. The study group comprised 21 consecutive adult patients (18 undergoing haemodialysis and 3 with a renal graft) imaged using {sup 99m}Tc-sestamibi/{sup 123}I subtraction scintigraphy. Of the 21 patients, 12 had undergone one previous PTX and the other 9 between two and four parathyroid operations. All patients had symptoms and signs of severe RHPT. The mean serum PTH level was 1,142 pg/ml. {sup 99m}Tc-Sestamibi and {sup 123}I images were recorded simultaneously. Imaging views comprised a planar view of the neck and mediastinum, followed by a magnified pinhole view over the thyroid bed area. If parathyroid ectopy was detected, SPECT or SPECT-CT was performed. The forearm was imaged in case of autograft. Parathyroid scintigraphy was negative in one patient and positive in the other 20 (sensitivity 95.2%). One patient had uptake corresponding to two unresected parathyroid glands. Recurrence at the site of the partially resected gland or autograft was seen in 11 patients. However, six of them had a second {sup 99m}Tc-sestamibi focus corresponding to a supernumerary parathyroid gland. Seven other patients had a supernumerary parathyroid gland as the sole cause of relapse. Three of the supernumerary glands showed major ectopy (intrathyroidal, low mediastinal, undescended within the vagus nerve). One patient had parathyromatosis with multiple parathyroid nodules scattered over the left side of the neck. Reoperation was possible in 13 patients, with no false-positive findings. Many patients referred with the hypothesis of hyperplasia of a subtotally resected parathyroid gland or autograft were found to harbour a supernumerary parathyroid gland missed at the initial surgery.

    Full Text Available Abstract Background Hodgkin's disease (HD most commonly presents with progressive painless enlargement of peripheral lymph nodes, especially around the cervical region. A few children have systemic symptoms and weight loss. At the time of diagnosis, osseous involvement is uncommon Case presentation A case is described of Primary Multifocal Osseous Hodgkin's Lymphoma in a seven-year-old boy. He presented with a painful swelling in the sternum, and further investigations revealed deposits in his L1 vertebra, the left sacro-iliac joint and the right acetabulum. Conclusion The clinical, radiological and histological features of this disease can mimic other medical conditions, including Tuberculosis, making the diagnosis difficult and often leading to delays in treatment. This is a very rare condition and we believe this to be the youngest reported case in the literature.

    Full Text Available Progressive multifocal leukoencephalopathy (PML is a demyelinating disease of the CNS caused by reactivation of JC virus (JCV in a setting of cellular immunosuppression. Originally, PML was observed in patients with advanced HIV infection, lymphoproliferative disorders and transplant recipients. However, the widespread use of HIV antiretroviral drugs and the new selective immunomodulatory and immunosuppressive medications, such as Rituximab and Natalizumab, has recently modified the epidemiology, clinical presentation and prognosis of PML. Herein, we discuss the new concepts on PML, emphasizing the recent modification in the epidemiology; the impact of new immunomodulatory treatments in the disease, PML-IRIS (Immune reconstitution inflammatory síndrome, new treatment strategies and other JCV related CNS diseases.

    Noninfectious inflammatory lesions of the mandible occur in chronic recurrent multifocal osteomyelitis (CRMO). Diffuse sclerosing osteomyelitis of the mandible (DSOM) is a condition thought to be a localized form of CRMO. Recently, bisphosphonate therapy, and particularly intravenous pamidronate, has been proposed as a treatment for patients with both CRMO and DSOM who do not improve with nonsteroidal antiinflammatory drug treatment. We report our experience using pamidronate in 2 children with chronic noninfectious osteomyelitis affecting the mandible. We describe the clinical and radiographic features and the treatment, side effects, and clinical and radiographic responses. Our experience suggests that pamidronate is an effective second-line therapy.

  18. Contactin-1 and Neurofascin-155/-186 Are Not Targets of Auto-Antibodies in Multifocal Motor Neuropathy.

    Directory of Open Access Journals (Sweden)

    Kathrin Doppler

    Full Text Available Multifocal motor neuropathy is an immune mediated disease presenting with multifocal muscle weakness and conduction block. IgM auto-antibodies against the ganglioside GM1 are detectable in about 50% of the patients. Auto-antibodies against the paranodal proteins contactin-1 and neurofascin-155 and the nodal protein neurofascin-186 have been detected in subgroups of patients with chronic inflammatory demyelinating polyneuropathy. Recently, auto-antibodies against neurofascin-186 and gliomedin were described in more than 60% of patients with multifocal motor neuropathy. In the current study, we aimed to validate this finding, using a combination of different assays for auto-antibody detection. In addition we intended to detect further auto-antibodies against paranodal proteins, specifically contactin-1 and neurofascin-155 in multifocal motor neuropathy patients' sera. We analyzed sera of 33 patients with well-characterized multifocal motor neuropathy for IgM or IgG anti-contactin-1, anti-neurofascin-155 or -186 antibodies using enzyme-linked immunosorbent assay, binding assays with transfected human embryonic kidney 293 cells and murine teased fibers. We did not detect any IgM or IgG auto-antibodies against contactin-1, neurofascin-155 or -186 in any of our multifocal motor neuropathy patients. We conclude that auto-antibodies against contactin-1, neurofascin-155 and -186 do not play a relevant role in the pathogenesis in this cohort with multifocal motor neuropathy.

    We report a rare case of multifocal giant cell tumor of bone involving the trapezium, trapezoid, capitate, and scaphoid with soft tissue extension. Following intralesional resection, an autogenous corticocancellous iliac crest bone graft was used to fill the resultant defect and preserve carpal height and radiocarpal motion. Successful union with no recurrence was noted at 1-year follow-up.

  20. Frequency, risk factors and survival associated with an intrasubsegmental recurrence after radiofrequency ablation for hepatocellular carcinoma.

    Ryosuke Tateishi

    Full Text Available BACKGROUND: In the treatment of hepatocellular carcinoma (HCC, hepatic resection has the advantage over radiofrequency ablation (RFA in terms of systematic removal of a hepatic segment. METHODS: We enrolled 303 consecutive patients of a single naïve HCC that had been treated by RFA at The University of Tokyo Hospital from 1999 to 2004. Recurrence was categorized as either intra- or extra-subsegmental as according to the Couinaud's segment of the original nodule. To assess the relationship between the subsegments of the original and recurrent nodules, we calculated the kappa coefficient. We assessed the risk factors for intra- and extra-subsegmental recurrence independently using univariate and multivariate Cox proportional hazard regression. We also assessed the impact of the mode of recurrence on the survival outcome. RESULTS: During the follow-up period, 201 patients in our cohort showed tumor recurrence distributed in a total of 340 subsegments. Recurrence was categorized as exclusively intra-subsegmental, exclusively extra-subsegmental, and simultaneously intra- and extra-subsegmental in 40 (20%, 110 (55%, and 51 (25% patients, respectively. The kappa coefficient was measured at 0.135 (95% CI, 0.079-0.190; P<0.001. Multivariate analysis revealed that of the tumor size, AFP value and platelet count were all risk factors for both intra- and extra-subsegmental recurrence. Of the patients in whom recurrent HCC was found to be exclusively intra-subsegmental, extra-subsegmental, and simultaneously intra- and extra-subsegmental, 37 (92.5%, 99 (90.8% and 42 (82.3%, respectively, were treated using RFA. The survival outcomes after recurrence were similar between patients with an exclusively intra- or extra-subsegmental recurrence. CONCLUSIONS: The effectiveness of systematic subsegmentectomy may be limited in the patients with both HCC and chronic liver disease who frequently undergo multi-focal tumor recurrence.

    We report on markedly different frequencies of genetic lesions within subsets of chronic lymphocytic leukemia patients carrying mutated or unmutated stereotyped B-cell receptor immunoglobulins in the largest cohort (n=565) studied for this purpose. By combining data on recurrent gene mutations (BIRC3, MYD88, NOTCH1, SF3B1 and TP53) and cytogenetic aberrations, we reveal a subset-biased acquisition of gene mutations. More specifically, the frequency of NOTCH1 mutations was found to be enriched in subsets expressing unmutated immunoglobulin genes, i.e. #1, #6, #8 and #59 (22–34%), often in association with trisomy 12, and was significantly different (Pimmunoglobulin genes). Interestingly, subsets harboring a high frequency of NOTCH1 mutations were found to carry few (if any) SF3B1 mutations. This starkly contrasts with subsets #2 and #3 where, despite their immunogenetic differences, SF3B1 mutations occurred in 45% and 46% of cases, respectively. In addition, mutations within TP53, whilst enriched in subset #1 (16%), were rare in subsets #2 and #8 (both 2%), despite all being clinically aggressive. All subsets were negative for MYD88 mutations, whereas BIRC3 mutations were infrequent. Collectively, this striking bias and skewed distribution of mutations and cytogenetic aberrations within specific chronic lymphocytic leukemia subsets implies that the mechanisms underlying clinical aggressiveness are not uniform, but rather support the existence of distinct genetic pathways of clonal evolution governed by a particular stereotyped B-cell receptor selecting a certain molecular lesion(s).

    The aim of this study was to clinically assess the therapeutic effect of low-level laser therapy (LLLT) on chronic recurrent aphthous stomatitis (RAS) using a protocol we developed especially for the purpose. The study included 180 patients: group 1 (the study group) – 90 patients who received LLLT using a laser operating in the red spectrum (658 nm; in a non-contact mode; power output P = 27 mW; frequency f 1 = 5.8 Hz, f 2 – continuous waveform; time T = 1.14 min; dosage of 2 J/cm2 once daily); group 2 (controls) – 90 patients who received pharmacotherapy (Granofurin and solcoseryl given twice daily). The indices we assessed were pain intensity, erythema dynamics and epithelization time. Pain was completely managed in 55.6% of group 1 patients one day after therapy began, while it took three days to alleviate pain for 11.1% of the patients in group 2. The erythema was managed entirely in 24.4% of group 1 patients after the first session, while it did not change in any of the group 2 patients. Pain intensity and erythema had similar dynamics for both groups. In 5 days, 75.6% of group 1 patients showed complete epithelization, while in group 2 the process was completed in only 37.8% of patients. As a whole, the results we obtained using LLLT to treat chronic RAS were better than those obtained in the group receiving pharmacotherapy. Pain and inflammation were very effectively managed with LLLT with the parameters we used and epithelization was considerably accelerated. PMID:26019580

    Peripheral facial palsy is a clinical entity, which may be presented as the first symptom of multiple sclerosis (MS). Although MS is mostly a multifocal chronic inflammation of the central nervous system, peripheral nervous system can also be involved. Isolated cranial nerve palsies are rare and occur in 1.6% of MS patients. In this report, a case is presented of a 35-year-old woman who developed isolated seventh nerve palsy that was misdiagnosed as Bell's palsy. Despite recurrent peripheral facial palsy, positive cerebrospinal fluid finding and magnetic resonance imaging, the diagnosis of MS could only be confirmed when the patient developed other neurologic symptoms and when the criteria for dissemination in space were satisfied. In clinical presentation, the patient had only cranial nerve involvement, with complete recovery.

    A 15 years-old girl with no previous history of epilepsy or neurological disease presented three types of epileptic symptoms the same day: 1) clusters of rhythmic myoclonus of the left hemiface; 2) episodes of painful paresthesias of the left arm followed by secondary generalised seizures; 3) episodes of elementary visual hallucinations of the right hemifield. She had several seizures each hour and some were recorded. There were no EEG abnormalities during the facial myoclonus but rapid rhythms were seen during the sensory and visual partial seizures on the right parietal and left occipital lobes. There was no fever and no drowsiness. The CSF tap showed pleocytosis. Serological studies indicated recent mumps. The drugs were initially inefficient. The seizures disappeared after a month. The drugs were stopped after three months and the seizures had not relapsed after a one year's follow-up. Though there were no other sign of encephalitis, we believe that episode of multifocal seizures was due to mumps encephalitis.

  5. Multi-focal multiphoton lithography.

    Multiphoton lithography (MPL) provides unparalleled capabilities for creating high-resolution, three-dimensional (3D) materials from a broad spectrum of building blocks and with few limitations on geometry, qualities that have been key to the design of chemically, mechanically, and biologically functional microforms. Unfortunately, the reliance of MPL on laser scanning limits the speed at which fabrication can be performed, making it impractical in many instances to produce large-scale, high-resolution objects such as complex micromachines, 3D microfluidics, etc. Previously, others have demonstrated the possibility of using multiple laser foci to simultaneously perform MPL at numerous sites in parallel, but use of a stage-scanning system to specify fabrication coordinates resulted in the production of identical features at each focal position. As a more general solution to the bottleneck problem, we demonstrate here the feasibility for performing multi-focal MPL using a dynamic mask to differentially modulate foci, an approach that enables each fabrication site to create independent (uncorrelated) features within a larger, integrated microform. In this proof-of-concept study, two simultaneously scanned foci produced the expected two-fold decrease in fabrication time, and this approach could be readily extended to many scanning foci by using a more powerful laser. Finally, we show that use of multiple foci in MPL can be exploited to assign heterogeneous properties (such as differential swelling) to micromaterials at distinct positions within a fabrication zone.

    A double blind study with Solcoseryl compounds in ophthalmic gel and with 2.4% cystein in ophthalmic gel was performed in the period 1985-1988; it was used in 18 cases: with chronic recurrent keratitis (11 patients) and sicca keratitis (7 patients). Observed was the influence of these compounds on the epithelialization of the cornea, on the improvement of corneal transparency, the diminutation of the troubles connected with dessication of the eye in sicca keratitis. In spite of the small number of cases the observations were interesting. In patients with a chronic recurrent keratitis the influence of both compounds showed to be beneficial for the condition of the cornea. In patients with keratitis sicca one could observe a better tolerance of the Solcoseryl ophthalmic gel which could be applied for a longer period in comparison with cystein in gel.

    2016-01-01

    Compared with lens with one focal point,multifocal lens has a lower focusing quality with high background noise. This is arisen from the construction of multifocal lens, which is usually divided into several zones, with each corresponds to one focal point.Light passing through different zones cannot constructively interfere at the foci, resulting in a decreased optical performance. Here, we propose two multifocal metalenses with nanoslits arranged in an ellipse and a hyperbola, with both are able to focus incident light at their multifoci constructively, giving a better focusing properties than that designed by conventional methods.We theoretically and experimentally demonstrate that, within a broadband wavelength range (600-900 nm), the ellipse-shaped metalens (ESM) can focus the lights with opposite circular polarizations (CP) at its two focal points, respectively,while a hyperbola-shaped metalens (HSM) can only focus one particular CP light at its both foci, simultaneously.This types of conic-shaped metale...

    Epidermal growth factor (EGF) gene single-nucleotide polymorphism (SNP) is associated with an increased risk of hepatic tumors. The study aimed to elucidate the impact of EGF SNP and EGF receptor (EGFR) expression on the recurrence of hepatocellular carcinoma (HCC) after hepatectomy. To examine the impact of EGF SNP and EGFR on recurrent HCC, we retrospectively analyzed 141 HCC patients with chronic hepatitis C virus infection who underwent curative hepatectomy. The EGF *61 GG allele was present in 69 patients (48.9%), AG in 56 (39.7%) and AA in 16 (11.4%). The AA group had a significantly lower rate of intrahepatic metastasis (0% vs 16.5%, P = 0.02), lower serum EGF concentration (26.3 ± 15.9 pg/mL vs 43.4 ± 30.5 pg/mL, P = 0.02) and lower proportion of early recurrence (≤2 years; 28.6% vs 71.2%, P = 0.03) than the AG/GG group. The AA group had significantly higher recurrence-free survival than the AG/GG group (P = 0.04), but there was no significant difference in overall survival between these two groups (P = 0.97). High versus low EGFR expression analyzed by immunohistochemical staining in cancer cells was not significantly associated with overall survival (P = 0.37) or recurrence-free survival (P = 0.39). Therefore, EGF *61 AA was associated with a lower risk of recurrence after curative hepatectomy for HCC in patients with hepatitis C virus infection than other genotypes, but EGFR expression in cancer cells was not significantly associated with prognosis.

    Chronic non-bacterial osteomyelitis (CNO) has been known for over of 40 years. It is an underrecognized entity due to the low number of described cases and poor propagation awareness of the problem. Chronic non-bacterial osteomyelitis is usually confused with infectious spondylodiscitis or malignant lesions, both primary and metastatic. Failing to consider CNO as one of possible lesions of the spine among an array of differential diagnoses may lead to a prolonged ineffective treatment increasing treatment-related morbidity. In this paper the authors describe these two syndromes, with a possible autoimmune background - chronic recurrent multifocal osteomyelitis (CRMO) and SAPHO syndrome - that include CNO being among the manifestations. The authors present the spinal symptomatology of CNO for both syndromes published so far to help spine clinicians organize the information for better usage in everyday clinical practice.

    2015-03-01

    Multifocal motor neuropathy (MMN) with conduction block (CB) is a rare chronic immune-mediated neuropathy, but important to diagnose as it is treatable. The key features in prototypic MMN are electrodiagnostic demonstration of focal CB away from common sites of entrapment and normal sensory conduction across these sites. However, there are challenges in distinguishing CB from the effects of abnormal temporal dispersion. Consensus electrodiagnostic criteria, reinforced by modeling studies, are available to support definite or probable CB. In addition, consideration of technical issues can guard against false-positive and false-negative conclusions. These include limb temperature, stimulus site, inadvertent stimulating electrode movement, and supramaximal and submaximal responses, as well as the possibility of Martin-Gruber anastamosis. Robust evidence supports the treatment of MMN with intravenous immunoglobulin, and guidelines have been developed. Application of practical and simple rules including a 4-step diagnostic algorithm can help practitioners correctly diagnose this treatable condition and improve patient outcomes.

    We report 11 patients with multifocal acquired demyelinating sensory and motor (MADSAM) neuropathy, defined clinically by a multifocal pattern of motor and sensory loss, with nerve conduction studies showing conduction block and other features of demyelination. The clinical, laboratory, and histological features of these patients were contrasted with those of 16 patients with multifocal motor neuropathy (MMN). Eighty-two percent of MADSAM neuropathy patients had elevated protein concentrations in the cerebrospinal fluid, compared with 9% of the MMN patients (P < 0.001). No MADSAM neuropathy patient had elevated anti-GM1 antibody titers, compared with 56% of MMN patients (P < 0.01). In contrast to the subtle abnormalities described for MMN, MADSAM neuropathy patients had prominent demyelination on sensory nerve biopsies. Response to intravenous immunoglobulin treatment was similar in both groups (P = 1.0). Multifocal motor neuropathy patients typically do not respond to prednisone, but 3 of 6 MADSAM neuropathy patients improved with prednisone. MADSAM neuropathy more closely resembles chronic inflammatory demyelinating polyneuropathy and probably represents an asymmetrical variant. Given their different clinical patterns and responses to treatment, it is important to distinguish between MADSAM neuropathy and MMN.

    Two cases of multifocal white matter lesions occurring after viral illness are reported. Evoked potentials study and cranial magnetic resonance imaging (T2-weighted image) showed early abnormalities while CT scan was initially normal. Patients improved dramatically with steroid therapy. It would seem that because of a considerable responsiveness to steroids this affection should be differentiated from other types of encephalitis. Relations with multiple sclerosis are discussed.

    Multifocal epithelial hyperplasia (MEH) is also known as focal epithelial hyperplasia, Heck's disease or multifocal papillomavirus-induced epithelial hyperplasia. It is characterised by the presence of multiple lesions in the oral mucosa of children and it has been associated with the presence of the human papillomavirus. The aim of this study was to determine the clinico-pathological features of the cases diagnosed as MEH in the Service of Dermatology of the Hospital Manuel Gea González (SDHMGG). The files of the SDHMGG were reviewed and all cases diagnosed as MEH were retrieved. Nine MEH cases were found. Most of the patients were 20 year-old or younger (67%) and females were more commonly affected (78%). All patients presented multiple lesions and always, close relatives with similar lesions were found. Lesions were located most commonly in the buccal mucosa, lower lip and commissures. MEH is a soft tissue intraoral condition that needs treatment solely of the traumatised lesions or those with cosmetic problems. Remaining lesions will disappear with the age of the patients. It is suggested that this entity should be named multifocal epithelial hyperplasia since this name describes better the clinico-pathological and microscopic features of the disease.

    Full Text Available Objective: The purpose of this study is to present our experience with MRI evaluation of multifocal liver lesions in children and describe the MRI characteristics of these lesions. Patients and Methods: A retrospective review of consecutive MRI exams performed for the evaluation of multiple liver lesions between 1 January 2007 and 31 December 2012 was done to note the number of lesions, the size of the largest lesion, MR signal characteristics, and background liver. Final diagnosis was assigned to each case based on pathology in the available cases and a combination of clinical features, imaging features, and follow-up in the remaining cases. Results: A total of 48 children (22 boys, 26 girls; age between 3 months and 18 years with average age 10.58 years and median age 11 years were included in the study. Totally 51 lesion diagnoses were seen in 48 children that included 17 focal nodular hyperplasia (FNH, 8 hemangiomas, 7 metastases, 6 regenerative nodules, 3 adenomas, 3 abscesses, and one each of angiomyolipoma, epithelioid hemangioendothelioma, focal fatty infiltration, hepatocellular carcinoma, hepatic infarction, nodular regenerative hyperplasia, and hepatic cyst. Background liver was normal in 33, cirrhotic in 10, fatty in 3, and siderotic in 2 children. Most FNH, hemangiomas, and regenerative nodules showed characteristic MRI features, while metastases were variable in signal pattern. Conclusion: Many commonly seen multifocal liver lesions in children have characteristic MRI features. MRI can help to arrive at reasonable differential diagnoses for multifocal liver lesions in children and guide further investigation and management.

    Full Text Available A young female patient presenting with recurrent hemoptysis, neck swelling, and mediastinal mass mimicking lymphadenopathy was admitted to the Institute of Post Graduate Medical Education and Research and SSKM hospital, Kolkata, India. Clinical features, radiological studies, fibre optic bronchoscopy, and fine needle aspiration cytology from the neck swelling created a diagnostic dilemma until surgical resection and immunohistochemistry reports confirmed the diagnosis of multifocal epithelioid hemangioendothelioma, a rare vascular tumor with intermediate malignancy potential. Because it is a slow-progressing disease and due to the non-availability of standard chemotherapy, the patient, and her legal guardian, opted for palliative care only. She was asymptomatic for four years but again presented with hemoptysis, reappearance of the neck swelling on the same side, and a mediastinal mass compressing the superior vena cava and right pulmonary artery. This report describes the diagnostic problems and therapeutic challenges in the management of this rare tumor over a four-year follow-up period. The clinical course emphasizes the highly unpredictable nature of this tumor.

The progressive subretinal fibrosis syndrome is a severe subset of multifocal choroiditis. The clustering of lesions around the nerve optic head may mean that the disease is spread through the flow in and out of the eye around the optic nerve.Descrevemos um caso de fibrose sub-retiniana progressiva e corrioretinite multifocal granulomatosa junto com os achados de angiografia fluoresceínica e com indocianina verde e propomos uma nova fisiopatologia para a fibrose em anel justa-papilar. A síndrome de fibrose sub-retiniana progressiva é uma doença grave, rara e constitui um subtipo grave da coroidite multifocal. As múltiplas lesões com fibrose circundando o disco óptico podem significar que a doença é oriunda do fluxo do líquido céfalo-raqueano, ao redor do nervo óptico.

    Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease caused by reactivation of JC virus in immunosuppressed patients. The diagnosis is usually suggested on imaging and confirmed by cerebrospinal fluid polymerase chain reaction (PCR) for JC virus DNA. In this article, we review the imaging manifestations of PML on computed tomography (CT), magnetic resonance imaging (MRI), diffusion-weighted imaging (DWI), diffusion tensor imaging (DTI), MR spectroscopy, single photon-emission computed tomography (SPECT) and positron-emission tomography (PET), and outline the role of imaging in follow-up and prognostication.

  3. Results of surgery for chronic pulmonary Aspergillosis, optimal antifungal therapy and proposed high risk factors for recurrence - a National Centre’s experience

    Science.gov (United States)

    2013-01-01

    Background Surgery for pulmonary aspergillosis is infrequent and often challenging. Risk assessment is imprecise and new antifungals may ameliorate some surgical risks. We evaluated the medical and surgical management of these patients, including perioperative and postoperative antifungal therapy. Methods Retrospective study of patients who underwent surgery for pulmonary aspergillosis between September 1996 and September 2011. Results 30 patients underwent surgery with 23 having a preoperative tissue diagnosis while 7 were confirmed post-resection. The median age was 57 years (17–78). The commonest presenting symptoms were cough (40%, n = 12) and haemoptysis (43%, n = 13). Twelve (40%) patients had simple aspergilloma (including 2 with Aspergillus nodules) while the remaining 18 (60%) had chronic cavitary pulmonary aspergillosis (CCPA) (complex aspergilloma). Most of the patients had underlying lung disease: tuberculosis (20%, n = 6), asthma (26%, n = 8) and COPD (20%, n = 6). The procedures included lobectomy 50% (n = 15), pneumonectomy 10% (n = 3), sublobar resection 27% (n = 8), decortication 7% (n = 2), segmentectomy 3% (n = 1), thoracoplasty 3% (n = 1), bullectomy and pleurectomy 3% (n = 1), 6% (n = 2) lung transplantation for associated disease. Median hospital stay was 9.5 days (3–37). There was no operative and 30 day mortality. Main complications were prolonged air leak (n = 7, 23%), empyema (n = 6, 20%), respiratory failure requiring tracheostomy /reintubation (n = 4, 13%). Recurrence of CCPA was noted in 8 patients (26%), most having prior CCPA (75%). Taurolidine 2% was active against all 9 A. fumigatus isolates and used for pleural decontamination during surgery. Conclusions Surgery in patients with chronic pulmonary aspergillosis offered good outcomes with an acceptable morbidity in a difficult clinical situation; recurrence is problematic. PMID:23915502

    Full Text Available Multi-focal vision systems comprise cameras with various fields of view and measurement accuracies. This article presents a multi-focal approach to localization and mapping of mobile robots with active vision. An implementation of the novel concept is done considering a humanoid robot navigation scenario where the robot is visually guided through a structured environment with several landmarks. Various embodiments of multi-focal vision systems are investigated and the impact on navigation performance is evaluated in comparison to a conventional mono-focal stereo set-up. The comparative studies clearly show the benefits of multi-focal vision for mobile robot navigation: flexibility to assign the different available sensors optimally in each situation, enhancement of the visible field, higher localization accuracy, and, thus, better task performance, i.e. path following behavior of the mobile robot. It is shown that multi-focal vision may strongly improve navigation performance.

  5. Evolving paradigms in multifocal breast cancer.

    Salgado, Roberto; Aftimos, Philippe; Sotiriou, Christos; Desmedt, Christine

    2015-04-01

    The 7th edition of the TNM defines multifocal breast cancer as multiple simultaneous ipsilateral and synchronous breast cancer lesions, provided they are macroscopically distinct and measurable using current traditional pathological and clinical tools. According to the College of American Pathologists (CAP), the characterization of only the largest lesion is considered sufficient, unless the grade and/or histology are different between the lesions. Here, we review three potentially clinically relevant aspects of multifocal breast cancers: first, the importance of a different intrinsic breast cancer subtype of the various lesions; second, the emerging awareness of inter-lesion heterogeneity; and last but not least, the potential introduction of bias in clinical trials due to the unrecognized biological diversity of these cancers. Although the current strategy to assess the lesion with the largest diameter has clearly its advantages in terms of costs and feasibility, this recommendation may not be sustainable in time and might need to be adapted to be compliant with new evolving paradigms in breast cancer.

    The immunochemical study of the blood sera of children with chronic and relapsing infections has shown an increase in the content of alpha 2-macroglobulin and alpha 1-antitrypsin in the absence of significant changes in the concentration of immunoglobulins and complement components. The immunochemical analysis of the system of soluble leukocytic antigens (SLA) has revealed a decrease in the level of SLA-1 simultaneously with the presence of redundant amounts of SLA-5 and SLA-8.

  8. Differential Gene Expression Profiles and Selected Cytokine Protein Analysis of Mediastinal Lymph Nodes of Horses with Chronic Recurrent Airway Obstruction (RAO Support an Interleukin-17 Immune Response.

    Directory of Open Access Journals (Sweden)

    Alexandra Korn

    Full Text Available Recurrent airway obstruction (RAO is a pulmonary inflammatory condition that afflicts certain mature horses exposed to organic dust particulates in hay. Its clinical and pathological features, manifested by reversible bronchoconstriction, excessive mucus production and airway neutrophilia, resemble the pulmonary alterations that occur in agricultural workers with occupational asthma. The immunological basis of RAO remains uncertain although its chronicity, its localization to a mucosal surface and its domination by a neutrophilic, non-septic inflammatory response, suggest involvement of Interleukin-17 (IL-17. We examined global gene expression profiles in mediastinal (pulmonary-draining lymph nodes isolated from RAO-affected and control horses. Differential expression of > 200 genes, coupled with network analysis, supports an IL-17 response centered about NF-κB. Immunohistochemical analysis of mediastinal lymph node sections demonstrated increased IL-17 staining intensity in diseased horses. This result, along with the finding of increased IL-17 concentrations in lymph node homogenates from RAO-affected horses (P = 0.1 and a down-regulation of IL-4 gene and protein expression, provides additional evidence of the involvement of IL-17 in the chronic stages of RAO. Additional investigations are needed to ascertain the cellular source of IL-17 in this equine model of occupational asthma. Understanding the immunopathogenesis of this disorder likely will enhance the development of therapeutic interventions beneficial to human and animal pulmonary health.

    2014-01-01

    Full Text Available Introduction. The optimal initial management of parotid pleomorphic adenomas reduces the risk of recurrence and malignant transformation. Surgery of recurrence can be difficult in multinodular disseminated forms. Case Report. A 67-years-old patient was referred for management of a large multifocal recurrence of a pleomorphic adenoma operated on 23 years ago. The clinical and radiological assessment found parapharyngeal, infratemporal, and prestyloid invasion, with nodules in the sternocleidomastoid muscle. Excision by transmandibular approach was performed. The pathologist found a multinodular recurrent pleomorphic adenoma without criteria of malignancy. Postoperative radiotherapy was performed. Discussion. Multinodular forms and incomplete resections are the most important factors that are thought to predispose to recurrence. A precise analysis of the extension by preoperative MRI is essential. Adjuvant radiotherapy can be given in these recurrent multifocal forms.

    We compared the clinical, electrophysiological, laboratory, and pathological features of 13 patients with Lewis-Sumner syndrome (LSS) with those of 20 patients with multifocal motor neuropathy (MMN). LSS and MMN patients have several common clinical features: age at onset, weakness in the distribution of individual peripheral nerves, mild wasting, cramps and fasciculations, partial areflexia, and frequent stepwise disease course. Cerebrospinal fluid protein level was normal or slightly elevated, but always less than 100 mg/dl. Conduction blocks are the electrophysiological hallmarks of these two neuropathies, and no differences in distribution and number of blocks were found. Contrary to MMN, lower-limb involvement at onset was frequent in LSS but extension to the upper limbs was a frequent later feature of the disease. Cranial nerve involvement was noted in 4 LSS patients during relapses and absent in all MMN patients. The major distinguishing features were the clinical and electrophysiological sensory involvement in LSS, and the lack of anti-GM1 antibodies in LSS, whereas IgM anti-GM1 were found in 40% of MMN patients. Some LSS patients responded to steroid therapy, whereas this was ineffective in MMN. From these features, LSS can be considered an entity distinct from MMN, with its own clinical, laboratory, and electrophysiological characteristics, and as an intermediate link between chronic inflammatory demyelinating polyneuropathy and MMN.

    Full Text Available Varicocele recurrence is one of the most common complications associated with varicocele repair. A systematic review was performed to evaluate varicocele recurrence rates, anatomic causes of recurrence, and methods of management of recurrent varicoceles. The PubMed database was evaluated using keywords "recurrent" and "varicocele" as well as MESH criteria "recurrent" and "varicocele." Articles were not included that were not in English, represented single case reports, focused solely on subclinical varicocele, or focused solely on a pediatric population (age <18. Rates of recurrence vary with the technique of varicocele repair from 0% to 35%. Anatomy of recurrence can be defined by venography. Management of varicocele recurrence can be surgical or via embolization.

    Renal cell carcinoma (RCC) in autosomal dominant polycystic kidney (ADPKD) is rare. To date, 54 cases of RCC in ADPKD have been reported. Among these, only 2 cases have different histologic types of RCC. Here we describe a 45-year-old man who received radical nephrectomy for multifocal RCC with synchronous papillary and clear cell histology in ADPKD and chronic renal failure under regular hemodialysis. The case reported herein is another example of the rare pathological finding of RCC arising in a patient with ADPKD.

    In this paper, the authors try to motivate their preference for implanting AT.Lisa Multifocals from all other premium IOL's from the market. It is emphasized, through clinical examples, that their choice comes after a long experience with this type of mul- tifocals IOL's. We make a short presentation of this particular type of MIOL's with their good but also weak points and try to motivate our decision to change from other types. We present the steps that each patient has to follow in our clinic prior to surgery itself, stressing out the idea that the discussion with the patient is very important in taking a decision regarding the implantation of a Premium IOL.

    Progressive multifocal leukoencephalopathy (PML) is a rare disease of the immunosuppression that results from neurotropic invasion of the JC virus which leads to demyelination of oligodendrocytes. Immune reconstitution inflammatory syndrome (IRIS), on the other hand, is a condition of inflammation that develops as the immune system reconstitutes. This case report describes a case of a 35-year-old HIV-negative male who presented with three weeks of right lower extremity paresthesias as well as right upper extremity apraxia. He was diagnosed with PML complicated by IRIS secondary to Rituximab, which he had completed four months prior to presentation. Despite the condition's poor prognosis, the patient recovered with only minor deficits. PMID:27965904

    Progressive multifocal leukoencephalopathy (PML) has been identified as a serious adverse drug reaction (ADR) of several immunomodulatory biologicals. In this study, we contrasted the reporting patterns of PML for two biologicals for which the risk was identified at different points...... in their lifecycle: natalizumab (before reapproval) and rituximab (nine years postapproval). We found that, apart from the differences in clinical characteristics (age, gender, indication, time to event, fatality), which reflect the diversity in context of use, PML reports for natalizumab were more complete and were...... received sooner after occurrence. This study serves as an important reminder that spontaneous reports should only be used with great caution to quantify and compare safety profiles across products over time. The observed variability in reporting patterns and heterogeneity of PML cases presents challenges...

  17. Multifocal motor neuropathy: update on clinical characteristics, pathophysiological concepts and therapeutic options.

    Science.gov (United States)

    Meuth, Sven G; Kleinschnitz, Christoph

    2010-01-01

    Multifocal motor neuropathy (MMN) is an acquired immune-mediated neuropathy characterized by chronic or stepwise progressive asymmetrical limb weakness without sensory deficits. The upper extremities are more often affected than the lower extremities with distal paresis dominating over proximal paresis. Important diagnostic features are persistent multifocal partial conduction blocks (CBs) and the presence of high-titer anti-GM1 serum antibodies. Motor neuron disease, other chronic dysimmune neuropathies, such as chronic inflammatory demyelinating polyneuropathy and the Lewis-Sumner syndrome (MADSAM neuropathy), are important differential diagnoses. While corticosteroids and plasma exchange are largely ineffective, high-dose intravenous immunoglobulins are regarded as first-line treatment. In spite of significant success in elucidating the underlying disease mechanisms in MMN during the past few years, important pathophysiological issues and the optimum long-term therapy remain to be clarified. The present review summarizes the clinical picture and current pathophysiological concepts of MMN with a special focus on the molecular and electrophysiological basis of CBs and highlights established therapies as well as possible novel treatment options.

  18. Conservative surgery for multifocal/multicentric breast cancer.

    Nijenhuis, Matthijs V; Rutgers, Emiel J Th

    2015-11-01

    Multifocal (MF) and multicentric (MC) breast cancer is regularly considered a relative contraindication for breast-conserving therapy (BCT). There are two reasons for this wide spread notion: However, we concur that if optimal 'cytoreductive surgery' is achieved this will result in good local control (i.e. in-breast relapse breast irradiation and systemic treatments as indicated by primary cancer biology. Careful planning and adaptive application of oncoplastic techniques will result in an optimal cosmetic results. The meticulous work of Roland Holland and coworkers(1) in the early 1980's on whole breast specimen showed invasive foci at more then 2 cm distance from the invasive primary cancer in more then 40% of specimen. Although multiple tumor foci may occur in up to 60% of mastectomy specimens, equivalent survival outcomes were observed in prospective trials comparing BCT and mastectomy for clinically unifocal lesions, suggesting that the majority of these foci are not, or do not become, biologically relevant or clinically significant with appropriate treatment. As diagnostic tools advance, MF and MC tumors are more commonly diagnosed. Cancers that previously would have been classified as unifocal now can be detected as MF or MC. In addition, locoregional treatment modalities have improved significantly over the past decade. More recent studies reflect these advances in diagnosis and treatment. Studies evaluated staging MRI showed that up to 19% of woman with diagnosed breast cancer harbor a second malignant ipsilateral lesion. These findings should only have consequences when additional lesions are proven cancer. Multiple enhancing lesions on MRI are in itself not an indication for a mastectomy. The Z0011 trial and the AMAROS trial demonstrated a similar phenomenon for axillary treatment; less surgery does not necessarily lead to inferior local control or survival outcomes. Recent studies supplement the growing evidence that treatment of patients with MF

Recognizing proposed clinical and autoimmune similarities between SC and PANDAS (pediatric autoimmune neuropsychiatric disorder associated with a streptococcal infection, we sought to identify serial biomarker changes in a slightly different population. Antineuronal antibodies were measured in eight children (mean 11.3 years with chronic, dramatic, recurrent tics and obsessive-compulsive disorder (OCD associated with a group A β-hemolytic streptococcal (GABHS respiratory tract infection, but differing because they lacked choreiform movements. Longitudinal serum samples in most subjects included two pre-exacerbation samples, Exac, one midst Exac (abrupt recurrence of tic/OCD; temporally association with a GABHS infection in six of eight subjects, and two post-Exac. Controls included four groups of unaffected children (n = 70; mean 10.8 years obtained at four different institutions and published controls. Clinical exacerbations were not associated with a significant rise in antineuronal antibody titers. CaMKII activation was increased at the GABHS exacerbation point in 5/6 subjects, exceeded combined and published control's 95th percentile at least once in 7/8 subjects, and median values were elevated at each time point. Anti-tubulin and anti-D2R titers did not differ from published or combined control group's 95th percentile or median values. Differences in anti-lysoganglioside-GM1 and anti-D1R titers were dependent on the selected control. Variances in antibody titers and CaMKII activation were identified among the institutional control groups.

    Objective To evaluate the efficacy of canakinumab, a high-affinity human monoclonal anti-interleukin-1β antibody, in inducing complete or almost complete responses in patients with active tumour necrosis factor receptor-associated periodic syndrome (TRAPS). Methods Twenty patients (aged 7–78 years) with active recurrent or chronic TRAPS were treated with canakinumab 150 mg every 4 weeks for 4 months (2 mg/kg for those ≤40 kg) in this open-label, proof-of-concept, phase II study. Canakinumab was then withdrawn for up to 5 months, with reintroduction on relapse, and 4 weekly administration (subsequently increased to every 8 weeks) for 24 months. The primary efficacy variable was the proportion of patients achieving complete or almost complete response at day 15, defined as clinical remission (Physician's Global Assessment score ≤1) and full or partial serological remission. Results Nineteen patients (19/20, 95%; 95% CI 75.1% to 99.9%) achieved the primary efficacy variable. Responses to canakinumab occurred rapidly; median time to clinical remission 4 days (95% CI 3 to 8 days). All patients relapsed after canakinumab was withdrawn; median time to relapse 91.5 days (95% CI 65 to 117 days). On reintroduction of canakinumab, clinical and serological responses were similar to those seen during the first phase, and were sustained throughout treatment. Canakinumab was well tolerated and clinical responses were accompanied by rapid and sustained improvement in health-related quality of life. Weight normalised pharmacokinetics of canakinumab, although limited, appeared to be consistent with historical canakinumab data. Conclusions Canakinumab induces rapid disease control in patients with active TRAPS, and clinical benefits are sustained during long-term treatment. Trial registration number NCT01242813; Results.

    Background The aim of this study was to evaluate the clinical and microbiological effects of local application minocycline HCl 2% gel, used as an adjunct to scaling and root planing (SRP) for treatment of chronic periodontitis (CP). CP is an inflammation of periodontal tissue that is caused mainly by bacterial infection, where periodontal destruction such as loss of attachment and bone destruction occurred. Methods A total of 81 subjects with moderate to severe periodontitis whose baseline clinical attachment loss (CAL) was ≥4 mm were randomly assigned to receive SRP alone (control group, N=39) or SRP followed by four times of local application of minocycline HCl gel (Periocline) once a week (test group, N=42). Pocket depth, CAL, and papilla bleeding index were examined at baseline, 21 days, 2, 3, and 6 months. Subgingival plaque samples were collected with sterile curettes and were analyzed by real-time polymerase chain reaction for the presence of three periodontal pathogens (Porphyromonas gingivalis [P.g.], Tannerella forsythia [T.f.], and Treponema denticola [T.d.]) at baseline, 2, 3, and 6 months. Results The number of bacteria was reduced in both groups at 2 months after baseline (SRP treatment). The changes (2–6 months) in T.d. and T.f. counts in the test group were significantly lower than those in the control group. In the control group, a significant regrowth of P.g., T.f., and T.d. was observed from 2 to 6 months and of P.g. and T.f. from 3 to 6 months. On the other hand, in the test group, the number of the three bacteria did not significantly increase during the 6-month period. Conclusion The results showed that local application of minocycline, used as an adjunct to SRP, was effective for suppressing regrowth of periodontal pathogens, suggesting its risk reduction of recurrent periodontal pathogens in CP.

    Vulvovaginitis (VV) is one of the most commonly encountered problems by a gynecologist. Many women frequently self-treat with over-the-counter medications, and may present to their health-care provider after a treatment failure. Vulvovaginal candidiasis, bacterial vaginosis, and trichomoniasis may occur as discreet or recurrent episodes, and have been associated with significant treatment cost and morbidity. We present an update on diagnostic capabilities and treatment modalities that address recurrent and refractory episodes of VV.

    Objective To explore the risk factors related to recurrent chronic subdural hematoma (CSDH). Methods 171 cases with CSDH were retrospectively analyzed. Results 18 cases were recurrent after surgery with a recurrent rate of 10.5%. Single factor Χ2 analysis showed that the recurrence of CSDH was related to age, hematoma density, hematoma location, midline shift, Bender classfication, encephalatrophy classfication,drainage amount, and bleeding tendency (P < 0.05), regardless of gender,anesthesia mode,and injury history (P > 0.05). Age, hematoma density, midline shift, Bender classfication,encephalatrophy classfication,and bleeding tendency were found to be independently associated with the recurrence of CSDH by Logistic multifactorial analysis (P < 0. 05). Conclusions Patient age,hematoma density, midline shift, Bender classfication, encephalatrophy classfication, and bleeding tendency are prognostic factors fpatients for with CSDH. We should pay more attention to the recurrent risk factors,and implement corresponding prevention strategies.%目的 探讨慢性硬膜下血肿(chronic subdural hematoma,CSDH)术后复发的相关因素.方法 回顾性分析171例CSDH患者的临床资料.结果 本组CSDH患者术后共有18例复发,复发率为10.5%.单因素χ<'2>检验显示CSDH术后复发与年龄、血肿密度、血肿位置、中线移位、Bender分级、脑萎缩分级、引流量和出血倾向相关(P<0.05).与性别、麻醉方式和有无外伤史无关(P>0.05).Logistic多因素分析显示年龄,血肿密度、中线移位、Bender分级、脑萎缩分级和出血倾向为CSDH患者术后复发危险因素(P<0.05).结论 CSDH患者的年龄、血肿密度、中线移位、Bender分级和出血倾向与患者的预后密切相关,应针对复发的高危因素,做好相应的防治工作.

    Purpose:To test the feasibility of recording rod multifocal electroretinograms (ERG) in humans and observe appropriate recording conditions.Methods: Multifocal rod ERG were recorded using a stimulus array of 61 equalsized hexagons in two normal subjects after the dark adaptation. Flashes were blue (W47B). Blank frames between two successive flashes of hexagons varied from 0 to 14. Length of the m-sequence, bandwidth, flash frequency, flash intensities and background intensities were changed to obtain appropriate recording conditions for the clinical use.Results:Multifocal rod ERG were clearly recordable and well formed. They had an early implicit time, very small negative wave and a late implicit time, large positive wave. The positive wave was bimodal, whose timing and waveform were similar to the full-field rod ERG. The local response amplitudes can be suppressed with increase in flash frequency or background intensity, decrease in flash intensity or the size of stimulus elements.Conclusions: Multifocal rod ERG can be recorded in human and can provide topographical maps of retinal function that have clinical usage. 212-1 m-sequence length, 3F blank frames and 3~ 300 Hz bandwidth were suggested to appropriate recording conditions.

A 70-year-old woman reported gradual visual deterioration to 20/40 in the left eye two and a half years after uneventful cataract surgery with implantation of a diffractive multifocal IOL. Funduscopic examination showed an epiretinal membrane (ERM in the left eye. Increased macular traction was believed to cause the visual deterioration. Vitreous surgery with removal of the ERM was performed and triamcinolone acetonide (TA was injected intravitreally to visualize the residual vitreous cortex. Although the ERM was peeled successfully, the ability to focus on the vitreoretinal interface through the IOL required great effort with decreased contrast sensitivity and ghost images of the intravitreal TA crystals. The vision improved to 20/25 4 months postoperatively. Macular surgery can be performed in an eye with a diffractive multifocal IOL; however, decreased contrast sensitivity and ghost images may interfere with the intraoperative view through the diffractive IOL in complicated cases.Keywords: diffractive multifocal intraocular lens, intraoperative view

    Multifocal demyelinating neuropathy with persistent conduction block (Lewis-Sumner syndrome) is a variant of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), which often clinically simulates a motor neuron disease (MND). We report here three patients initially suspected to have MND, who later were diagnosed as a Lewis-Sumner syndrome. One of them showed a remarkable clinical improvement after immunoglobulin therapy. The definitive diagnosis of this syndrome rests upon nerve conduction studies, uncovering multiple sites of persistent conduction block. Technically, it is important to exclude insufficient stimulus which may lead to an erroneous impression of conduction block. Magnetic stimulation, as compared to electric current, elicited larger responses possibly because of deeper current penetration. We found this mode of stimulation useful especially in testing focal demyelination requiring full activation of a diseased nerve at a most proximal segment.

    Patients with metachronous bilateral renal cell carcinoma pose a significant challenge given the high mortality of renal cell carcinoma and the poor quality of life should dialysis become necessary. In addition, patients may be subject to morbidity due to potential multiple treatments of the multifocal renal tumors. We present the case of a 71-year-old woman with multifocal, bilateral clear cell carcinoma who maintained a minimal change in serum creatinine after undergoing unilateral radical nephrectomy, subsequent percutaneous radiofrequency ablation, percutaneous cryoablation, laparoscopic cryoablation, and open partial nephrectomy for recurrent renal cell carcinoma in a solitary kidney.

    An 11-year-old girl had four episodes of fever in a year, lasting 7-10 days and associated with headache and neck stiffness. She had a long history of recurrent urticaria, usually preceding the fevers. There was also a history of vague pains in her knees and in the small joints of her hands. Her serum C-reactive protein was moderately raised at 41 g/L (normal <8). Her rheumatologist felt the association of recurrent fevers that lasted 7 or more days with headaches, arthralgia and recurrent urticaria suggested one of the periodic fever syndromes. Genetic testing confirmed she had a gene mutation consistent with one of tumour necrosis factor receptor-associated periodic syndrome.

    Epithelioid hemangioendothelioma (EH) of bone is a rare vascular neoplasm characterized by epithelioid endothelial cells and a variable biologic behaviour. The principal sites of occurrence of this osteolytic tumor are the lower extremity and the axial skeleton. Approximately half of the cases present with multifocal disease. The latter feature can be helpful in suggesting the diagnosis of a vascular tumor; on the other hand, it strengthens the need for a skeletal survey or whole-body MRI/CT. We report on the clinical, histologic and radiologic features - including CT and MRI findings - of EH in a case of multifocal disease of the phalanges of the hand, a very uncommon anatomic site of affliction.

    In patients with multifocal neuropathy with conduction block (CB), CBs located between the root and Erb's point are not detected in nerve conduction studies. We therefore examined whether the triple-stimulation technique (TST) might provide a useful means of detecting CB proximal to Erb's point. Clinical assessments, extensive nerve conduction studies (NCS), conventional transcranial magnetic stimulation, and TST were performed on 10 patients with multifocal motor neuropathy with CB (MMNCB) and 6 patients with Lewis-Sumner syndrome. Conduction blocks located proximal to Erb's point were detected in 9 patients. Of the CBs, 58% were associated with muscle weakness. The use of TST to detect proximal CB improved the sensitivity of the American Association of Neuromuscular and Electrodiagnostic Medicine criteria for definite or probable MMNCB from 60% to 90%. Thus, the TST is a useful means for detection of proximal CB and gives NCS considerable additional diagnostic power.

    Purpose To determine the incidence and etiology of required retreatment after multifocal intraocular lens (IOL) implantation and to evaluate the methods and clinical outcomes of retreatment. Patients and methods A retrospective chart review of 416 eyes of 209 patients from one site that underwent uncomplicated cataract surgery with multifocal IOL implantation. Biometry, the IOL, and refractive data were recorded after the original implantation, with the same data recorded after retreatment. Comments related to vision were obtained both before and after retreatment for retreated patients. Results The multifocal retreatment rate was 10.8% (45/416 eyes). The eyes that required retreatment had significantly higher residual refractive astigmatism compared with those who did not require retreatment (1.21±0.51 D vs 0.51±0.39 D, P<0.01). The retreatment rate for the two most commonly implanted primary IOLs, blended bifocal (10.5%, 16/152) and bilateral trifocal (6.9%, 14/202) IOLs, was not statistically significantly different (P=0.12). In those requiring retreatment, refractive-related complaints were most common. Retreatment with refractive corneal surgery, in 11% of the eyes, and piggyback IOLs, in 89% of the eyes, was similarly successful, improving patient complaints 78% of the time. Conclusion Complaints related to ametropia were the main reasons for retreatment. Residual astigmatism appears to be an important determinant of retreatment rate after multifocal IOL implantation. Retreatment can improve symptoms for a high percentage of patients; a piggyback IOL is a viable retreatment option. PMID:27041983

    Full Text Available Abstract Introduction Progressive multifocal leukoencephalopathy is an opportunistic infection occurring in patients with severe cellular immunodeficiency. This case highlights the role of cellular immunodeficiency in the reactivation of John Cunningham virus in a case of an early stage plasmacytoma. Case presentation A 76-year-old Caucasian woman presented with progressive left-sided hemiparesis, accompanied by hypoesthesia, hypoalgesia and neuropsychological symptoms. Magnetic resonance imaging demonstrated new hyperattenuating lesions in the right thalamus and left-sided subcortically. A polymerase chain reaction test revealed 4500 copies of John Cunningham virus-deoxyribonucleic acid/ml in cerebrospinal fluid. Human immunodeficiency virus infection was ruled out. A bone marrow biopsy showed an early stage immunoglobulin G-kappa plasmacytoma. Cidofovir (5mg/kg weekly for three weeks was started. A significant improvement of her neuropsychological symptoms was achieved, but motor system and sensory symptoms did not change. Conclusions This case shows a rapid course of progressive multifocal leukoencephalopathy with severe residual deficits. In the diagnostic workup of all patients with atypical neurologic symptoms or immunodeficiency, progressive multifocal leukoencephalopathy should be included as a differential diagnosis.

    Hertzberg, Yoni; Naor, Omer; Volovick, Alexander; Shoham, Shy

    2010-10-01

    Focused ultrasound (FUS) waves directed onto neural structures have been shown to dynamically modulate neural activity and excitability, opening up a range of possible systems and applications where the non-invasiveness, safety, mm-range resolution and other characteristics of FUS are advantageous. As in other neuro-stimulation and modulation modalities, the highly distributed and parallel nature of neural systems and neural information processing call for the development of appropriately patterned stimulation strategies which could simultaneously address multiple sites in flexible patterns. Here, we study the generation of sparse multi-focal ultrasonic distributions using phase-only modulation in ultrasonic phased arrays. We analyse the relative performance of an existing algorithm for generating multifocal ultrasonic distributions and new algorithms that we adapt from the field of optical digital holography, and find that generally the weighted Gerchberg-Saxton algorithm leads to overall superior efficiency and uniformity in the focal spots, without significantly increasing the computational burden. By combining phased-array FUS and magnetic-resonance thermometry we experimentally demonstrate the simultaneous generation of tightly focused multifocal distributions in a tissue phantom, a first step towards patterned FUS neuro-modulation systems and devices.

    Full Text Available Angiosarcomas of bone are rare tumors constituting 1% of all malignant bone tumors. They can be either solitary or multifocal and can easily be misinterpreted as multiple myeloma or metastasis radiologically. We present a case of multifocal angiosarcoma arrising in foot bones, the diagnosis of which was difficult clinically, radiologically and pathologically. The histologic findings observed in both bioptic and amputation specimens were provided.The patient was a 56 years-old man who has undergone coronary by-pass and saphenous vein surgery 3 months ago. He has been suffering from pain and swelling on left foot since then. The lesion was suspicious for atypical fungal infection, metastasis or lymphoma radiologically. “Tru-cut” biopsy revealed extensive necrosis and the lesion resembled an inflammatory and reactive process at first glance. Morphologic mimickers of the lesion like lymphoma, metastasis and small round cell tumors were excluded immunohistochemically and the diagnosis of “malignant vasculary tumor” was made upon CD- 31 positivity of tumor cells, presence of erytrocytes, cells with intracytoplasmic lumina and increased mitotic activity. In amputation specimen a multifocal tumor having areas of necrosis and hemorrhages was observed involving predominantly calcaneus but also infiltrating talus, distal tibia and achilles tendon. The maximum diameter of tumor was 5 cm in calcaneus. Adjuvant chemotherapy could not be given because of cardiac problems.The case was presented to increase awareness on this rare, diagnostically problematic issue, the classification of which is controversial.

    Purpose: To evaluate the clinical effects of implantation of Array multifocal intraocular lenses. Methods: Thirty-one cases (37 eyes) of cataract patients, including 15 males( 19 eyes)and 16 females( 18 eyes), were involved in this study. All patients underwent standard phacoemulsification with Array multifocal intraocular lens implantation. The complications during operation, postoperative distant visual acuity, near visual acuity,corneal curvature and visual symptoms were observed. Results: the mean value of best postoperative visual acuity was recorded as follows:uncorrected distant visual acuity was 0.8, the best-corrected distant visual acuity was 0.9, uncorrected near visual acuity was 0.5, near visual acuity with distant-corrected was 0.6, the best-corrected near visual acuity wss 0.9. The astigmatism of cornea was less than 1.5 D pre-operatively and post-operatively. One patient complained of glare. Conclusion: Array multifocal intraocular lens can provide good distant and near visual acuity. With observation of more cases and follow-up of longer time, we can draw a further conclusion.

    2013-01-01

    A 48-year-old woman presented with left abdominal pain and fullness. Computed tomography scan revealed a multicystic mass with multifocal mural nodules. Histologic examination showed a mucinous cystic tumor with cystadenoma, borderline malignant cystadenoma and cystadenocarcinoma, which were associated with sarcoma-like mural nodules (SLMNs) and multifocal anaplastic carcinoma. Mural nodules showed a positive reaction for CD56 and vimentin, but were negative for cytokeratin 7 and SMA. She underwent postoperative chemotherapy and is currently under follow-up; no recurrence or metastases were found in the first year of follow-up. Ovarian mucinous cystic tumor with SLMNs and foci of anaplastic carcinoma is extremely rare. To our knowledge, this case reports the most complex neoplastic and reactive components. Our findings shed some light on the pathogenesis of this rather rare carcinoma. We think that the formation of SLMNs may be the result of the reactive proliferation of undifferentiated mesenchymal cells, while the anaplastic carcinoma may be derived from mucinous epithelium. Moreover, because of difficulties encountered in their differential diagnosis, we think that the existence of foci of anaplastic carcinoma along with SLMNs necessitates careful histologic and immunohistochemical analysis of mural nodules for the determination of treatment and prognosis.

The case of a patient who underwent repeated sessions of neodymium: yttrium aluminum garnet (Nd:YAG laser therapy over a five-year period for the treatment of the watermelon stomach is presented. Postlaser therapy the patient developed deep ulcerations that would heal; however, he ultimately developed a nodular antrum. Random biopsies of antral nodules revealed carcinoma-in-situ. A Billroth I gastrectomy revealed two foci of carcinoma-in-situ/high grade dysplasia and multiple foci of lower grades of dysplasia. This case suggests a possible association between use of laser therapy and development of gastric neoplasia.

    A 53-year-old white woman developed diabetes mellitus, migratory erythema, and anemia, clinical features suggesting the presence of a "glucagonoma." Ten years earlier, after laparotomy and pancreatic biopsy, she had been told that she had an inoperable pancreatic carcinoma. Review of that biopsy together with current hormonal assay now confirms the diagnosis of glucagonoma. The recurrent peptic ulcer in this patient despite high levels of glucagon, a gastric inhibitory agent, is noted but not explained. An enhanced amylase-creatinine clearance ratio supports the notion that glucagon increases the clearances of amylase.

    BACKGROUND: Diagnostic parameters that can predict the presence of chronic pancreatitis (CP) in patients with recur-rent pain due to pancreatitis would help to direct appropri-ate therapy. This study aimed to compare the serum levels of monocyte chemoattractant protein-1 (MCP-1), transforming growth factor-β1 (TGF-β1), nerve growth factor (NGF), resis-tin and hyaluronic acid (HA) in patients with recurrent acute pancreatitis (RAP) and CP to assess their ability to differenti-ate the two conditions. METHODS: Levels of serum markers assessed by enzyme-linked immunosorbent assay (ELISA) were prospectively com-pared in consecutive patients with RAP, CP and in controls, and stepwise discriminant analysis was performed to identify the markers differentiating RAP from CP. RESULTS: One hundred and thirteen consecutive patients (RAP=32, CP=81) and 78 healthy controls were prospectively enrolled. The mean (SD) age of the patients was 32.0 (14.0) years; 89 (78.8%) were male. All markers were signiifcantly higher in CP patients than in the controls (P CONCLUSION: Serum resistin is a promising marker to dif-ferentiate between RAP and CP and needs validation in future studies, especially in those with early CP.

    A 64-year-old man was admitted to the Sun Yat-Sen University Cancer Center with chief complaints of recurrent abdominal pain and diarrhea for about 3 years and with a history of surgical repair for intestinal perforation owing to stress ulcer. Positron emission tomography (PET)/computed tomography (CT) demonstrated a primary tumor on the pancreatic tail with multifocal liver metastases. Pathological and immunohistochemistry staining revealed the lesion to be a pancreatic neuroendocrine tumor (pNET). According to the latest World Health Organization (WHO, 2013) classification, the tumor was classified as stage IV functional G1 pNET. After referral to the multidisciplinary treatment board (MDT), the patient was started on periodic dose of omeprazole, somatostatin analogues and Interferon α (IFNα) and had scanning follow-ups. Based upon the imaging results, CT-guided radioactive iodine-125 ((125)I) seeds implantation therapy, radiofrequency ablation therapy (RFA) or microwave ablation technique were chosen for the treatment of the primary tumor. Transarterial chemoembolization (TACE), RFA and microwave ablation techniques were decided upon for liver metastases. The patient showed beneficial response to the treatment with clinically manageable low-grade side effects and attained partial remission (RECIST criteria) with a good quality of life.

    Full Text Available Recurrent respiratory papillomatosis (RRP, which is caused exclusively by human papilloma virus (HPV, is a rare condition characterized by recurrent growth of benign papillomata in the respiratory tract. The papillomata can occur anywhere in the aerodigestive tract but most frequently in the larynx, affecting both children and adults. The management of this entity remains still challenging since no specific definitive treatment exists. Nevertheless, novel surgical interventions as well as several adjuvant therapies have shown promising results in the long-term palliative management of this debilitating disease. Despite its mostly benign nature, RRP may cause significant morbidity and mortality because of its unpredictable clinical course and especially its tendency, albeit infrequent, for malignant transformation. In this article, we present two patients with RRP; one underwent bronchoscopic laser ablation in combination with inhaled interferon-alpha administration that led to a long-term regression of the disease while the other patient was diagnosed with transformation to squamous cell lung carcinoma with fatal outcome. We include a review of the current literature with special emphasis on RRP management and the potential role of HPV in the development of lung cancer.

    Full Text Available The spectrum of chronic dysimmune neuropathies has widened well beyond chronic demyelinating polyradiculoneuropathy (CIDP. Pure motor (multifocal motor neuropathy, sensorimotor with asymmetrical involvement (multifocal acquired demylinating sensory and motor neuropathy, exclusively distal sensory (distal acquired demyelinating sensory neuropathy and very proximal sensory (chronic immune sensory polyradiculopathy constitute the variants of CIDP. Correct diagnosis of these entities is of importance in terms of initiation of appropriate therapy as well as prognostication of these patients. The rates of detection of immune-mediated neuropathies with monoclonal cell proliferation (monoclonal gammopathy of unknown significance, multiple myeloma, etc. have been facilitated as better diagnostic tools such as serum immunofixation electrophoresis are being used more often. Immune neuropathies associated with malignancies and systemic vasculitic disorders are being defined further and treated early with better understanding of the disease processes. As this field of dysimmune neuropathies will evolve in the future, some of the curious aspects of the clinical presentations and response patterns to different immunosuppressants or immunomodulators will be further elucidated. This review also discusses representative case studies.

    We report a case of pulmonary inflammatory myofibroblastic tumor (IMT) showing aggressive and unusually rapid progression. A 27-year-old woman was admitted to the emergency room due to dry cough, fever and blood-tinged sputum that lasted one week. Initial chest radiograph and computed tomography scan revealed multifocal pulmonary nodules, which subsequently progressed into large necrotic masses within two months. She underwent a fine needle biopsy of the largest mass in the right middle lung zone which revealed inflammatory myofibroblastic cells consistent with IMT. The masses showed complete regression after six months of corticosteroid therapy. This unusual clinical manifestation could help explain the reactive inflammatory nature associated with IMTs.

    Digital ulcers (DUs) are a severe and frequent clinical feature of patients with systemic sclerosis (SSc). The presence of DUs may cause severe pain and often lead to impairment of patient's functional activities and health-related quality of life. Moreover, poor patient cooperation during the wound care procedure due to pain may be associated with a negative outcome of DU healing. Therefore, pain management has a key role in patients with SSc. These two case reports describe the effectiveness and safety of oxycodone/naloxone in patients with SSc complicated by painful chronic DUs. Such a therapy has provided pain relief and consequently an increased compliance during redressing wounds.

    Pancreatic adenocarcinoma is the fourth cause of cancerrelated death in the United States. Surgery is the only potentially curative treatment, but most patients present at diagnosis with unresectable or metastatic disease. Moreover, even with an R0 resection, the majority of patients will die of disease recurrence. Most recurrencesoccur in the first 2-year after pancreatic resection, and are commonly located in the abdomen, even if distant metastases can occur. Recurrent pancreatic adenocarcinoma remains a significant therapeutic challenge, due to the limited role of surgery and radiochemotherapy. Surgical management of recurrence is usually unreliable because tumor relapse typically presents as a technically unresectable, or as multifocal disease with an aggressive growth. Therefore, treatment of patients with recurrent pancreatic adenocarcinoma has historically been limited to palliative chemotherapy or supportive care. Only few data are available in the Literature about this issue, even if in recent years more studies have been published to determine whether treatment after recurrence have any effect on patients outcome. Recent therapeutic advances have demonstrated the potential to improve survival in selected patients who had undergone resection for pancreatic cancer. Multimodality management of recurrent pancreatic carcinoma may lead to better survival and quality of life in a small but significant percentage of patients; however, more and larger studies are needed to clarify the role of the different therapeutic options and the optimal way to combine them.

    Background Papillary thyroid carcinoma (PTC) represents one of the most frequent endocrine malignancies.Several factors have been found to be involved in determining the outcome of treatment for patients with PTC.Large tumor size,diagnosis at an early age,extra-thyroidal invasion,aggressive histological variants,and distant metastases are the most important determinants of a poor outcome.BRAFv600E mutation has been found to be a major genetic alteration in PTC.This study aimed to evaluate progression in patients with multifocal and solitary PTC.Methods We performed a retrospective study to analyze 368 patients with PTC who underwent surgery,including 282 patients with solitary PTC and 86 patients with multifocal PTC.The status of BRAFv600E mutation in all tumor foci from multifocal PTC was detected.Results Our study suggested that multifocal PTC was more related to lymph node metastasis and vascular invasion than solitary PTC.However,the distant metastasis rate and 10-year survival rate showed no difference between these two groups.The number of tumor foci did not affect progression of disease in multifocal PTC patients.Lymph node metastasis in multifocal PTC patients was associated with larger tumors,diagnosis at early stage,and extra-thyroidal invasion.Conclusion The status of BRAFv600E mutation was more frequent in multifocal PTC patients with lymph node metastasis and diagnosis at later age.

    Full Text Available A significant increase in the incidental detection of small renal tumors has been observed with the routine use of cross-sectional abdominal imaging. However, the proportion of small renal tumors associated with multifocal RCC has yet to be established. Here then, we report our experience with the treatment of multifocal RCC in which the primary tumor was ≤4 cm. In our series of 1113 RCC patients, 5.4% (60/1113 had multifocal disease at the time of nephrectomy. Discordant histology was present in 17% (10/60 of patients with multifocal RCC. Nephron sparing surgery was utilized more frequently in patients with solitary tumors. Overall, cancer-specific, and distant metastasis-free survival appeared to be similar between multifocal and solitary tumors. These findings are consistent with previous series which evaluated multifocal RCC with tumors >4 cm. With the known incidence of multifocality RCC, careful inspection of the entire renal unit should be performed when performing nephron sparing surgery.

    To determine the clinical and the pathologic significance of the focal attenuation differences (FAD) and bile duct wall enhancement occurring in recurrent pyogenic cholangitis (RPC) and seen at multiphasic spiral CT. Among the multiphasic (non-contrast, arterial and portal or delayed phase) spiral CT findings of 60 consecutive patients, two types of FAD were noted during the non-contrast phase. These were Type A (iso) and Type B (low attenuation), and their distribution pattern (lobar versus patchy, multifocal) and the and the presence or absence of bile duct wall enhancement were recorded. The radiologic findings were correlated with the clinical and pathologic findings. Two types of FAD were noted in 40 of the 60 patients. Active in flammation was present in 19 of the 27 with Type-A and in ten of the 15 in whom the presence of RPC was pathologically proven. Ten of the 13 with Type-B FAD were in a subclinical state, and nine of the ten in whom RPC was pathologically proven had chronic inflammation. Among 20 patients who did not have FAD, RPC was subclinical in 18 and dormant in nine of the eleven in whom its presence was pathologically proven (p<0.001). Clinico-pathologic correlation with bile duct wall enhancement and the distribution pattern of FAD showed no statistical significance. The inflammatory activity of RPC can be predicted by analysis of the FAD seen at multiphasic spiral CT.

    Multifocal multiphoton microscopy (MMM) achieves fast imaging by simultaneously scanning multiple foci across different regions of specimen. The use of imaging detectors in MMM, such as CCD or CMOS, results in degradation of image signal-to-noise-ratio (SNR) due to the scattering of emitted photons. SNR can be partly recovered using multianode photomultiplier tubes (MAPMT). In this design, however, emission photons scattered to neighbor anodes are encoded by the foci scan location resulting in ghost images. The crosstalk between different anodes is currently measured a priori, which is cumbersome as it depends specimen properties. Here, we present the photon reassignment method for MMM, established based on the maximum likelihood (ML) estimation, for quantification of crosstalk between the anodes of MAPMT without a priori measurement. The method provides the reassignment of the photons generated by the ghost images to the original spatial location thus increases the SNR of the final reconstructed image.

    A 71-year-old man was investigated with electrodiagnostic testing 4 months after a deliberate quinine overdose. Initially he was admitted to intensive care unit with visual acuity (VA) of perception of light in both eyes. VA recovered to 6/6 right eye and 6/12 left eye, though severely constricted fields were noted. Slow stimulus (base period of 83 ms) multifocal electroretinogram (ERG) showed electronegative responses outside the inner 5 degrees, with a reduced but electropositive response seen in this central area. It appears that in this case of bilaterally negative ERGs that the macula/fovea (which has a vascular supply through the choroid) is relatively spared as is seen in bilateral vascular electronegative ERGs. This may indicate that quinine toxicity to the retina may be secondary to effects similar to vascular occlusion or severe ischemia during the acute phase of quinine poisoning. PMID:22693278

    We made a retrospective long-term follow-up study of 25 patients with multifocal motor neuropathy (Lewis-Sumner). The diagnosis was based upon criteria modified from those of AAEM (Sumner 1997). The electrophysiological findings indicating conduction block or focal demyelinative lesions were more diagnostic than anti-GM 1 antibody titers, which were elevated in only 40% of these patients. Demonstration of definite conduction block was not always possible in those patients who responded favorably to intravenous immunoglobulins (IVIg), whereas indirect pieces of evidence such as F-wave abnormalities or focal conduction delay or dispersion were equally helpful. IVIg had superior outcome to cyclophosphamide, which sometimes caused serious adverse effects. Three patients with severe axonal involvement showed elevated monospecific antibodies to GalNAc-GD1a.

    ABSTRACT Purpose To evaluate the optical power profiles of commercially available soft multifocal contact lenses and compare their optical designs. Methods The power profiles of 38 types of multifocal contact lenses—three lenses each—were measured in powers +6D, +3D, +1D, −1D, −3D, and −6D using NIMO TR1504 (Lambda-X, Belgium). All lenses were measured in phosphate buffered saline across 8 mm optic zone diameter. Refractive index of each lens material was measured using CLR 12-70 (Index Instruments, UK), which was used for converting measured power in the medium to in-air radial power profiles. Results Three basic types of power profiles were identified: center-near, center-distance, and concentric-zone ring-type designs. For most of the lens types, the relative plus with respect to prescription power was lower than the corresponding spectacle add. For some lens types, the measured power profiles were shifted by up to 1D across the power range relative to their labeled power. Most of the lenses were designed with noticeable amounts of spherical aberration. The sign and magnitude of spherical aberration can either be power dependent or consistent across the power range. Conclusions Power profiles can vary widely between the different lens types; however, certain similarities were also observed between some of the center-near designs. For the more recently released lens types, there seems to be a trend emerging to reduce the relative plus with respect to prescription power, include negative spherical aberration, and keep the power profiles consistent across the power range.

    Full Text Available Multifocal malignant tumors (MMT represent a comprehensive and multifaceted problem of clinical oncology.Today, as far as observations are accumulated, there are attempts to determine a real incidence rate of multifocal tumors. Research of MMT problem becomes more and more actual and significant in oncology. Several dozen thousands of MMT observations have been described all over the world for the recent 30 years. There is a stable trend towards the increase of the number of patients with such pathology. This is primarily concerned with the improvement of diagnostics, medical treatment and increased expectation of life.The increase in incidence of MMT is due to such factors as increased average expectation of life, increased intensity of carcinogenic effects, urbanization, accumulation of hereditary loading and improved diagnostics of oncologic diseases. Detection and record of such pathology are based first on detection of simultaneous tumors, second – on diagnostics of tumor and retrospective determination according to life record data of the first neoplasm, third – on determination of further tumor at regular follow-up, which requires prolonged and high quality examination of the patients.MMT most commonly develop in patients elder than 50 y. o., even in elder age in men than in women. The article describes a case of bilateral breast cancer in man. Clinicopathologic and immunohistochemical characteristics of the tumor were studied, the genetic polymorphisms were investigated by the method of polymerase chain reaction, associated with the risk of breast cancer development, genetic analysis of BRCA1 and BRCA2, blood cancer markers was done. Full equivalence of clinicopathologic and biological properties of tumor of the right and left mammae, witnessing the common etiology and pathogenesis of neoplastic process, was established.

    Abstract Introduction: Neurosarcoidosis accounts for approximately 5% of the sarcoidosis, which develops exclusively in the nervous system and is always difficult to diagnose. We describe a rare case of isolated neurosarcoidosis mimicking as multifocal meningiomas. A 27-year-old male was admitted to our hospital with a history of unconsciousness and convulsion 1 month ago, which was suspected as a seizure. The results showed no abnormalities in complete blood count; serum electrolytes; erythrocyte sedimentation rate and ultrasonography of the liver, pancreas, spleen, kidney and parotid gland, and so on. Chest radiograph and electroencephalogram were also normal. Serum-angiotensin-converting enzyme slightly increased. Normal opening pressure was shown in cerebrospinal fluid sampling, which includes 8/μL white blood cells, 0.93 g/L protein, and 3.03 mmol/L glucose. Enhanced magnetic resonance imaging revealed multifocal enhancement lesions, including left sphenoid wing region, left temporal and bilateral occipitoparietal region, which were suspected as multiple “meningioma”. A left frontotemporal craniotomy was further performed. Both necrotizing and non-necrotizing granulomas were revealed in the pathological specimen, most of which were associated with multinucleated giant cells and macrophages. We could also see the fibrosis and inflammatory reaction in the sample composed of lymphocytes, histiocytes, and plasma cells. Histopathological examination showed that the cells were positive for human CD68 (KP1), CD68 (PGM1), and CD163; however, they were negative for the AF, epithelial membrane antigen, and glial fibrillary acidic protein. Tuberculosis-deoxyribonucleic acid test and special stains for acid-fast bacilli and fungi were negative. The diagnosis was finally made as isolated neurosarcoidosis. Then the patient was treated with additional corticosteroid therapy. Serial imaging examination 4 months later revealed that the lesions extremely decreased

    Approximately 10-20% of chronic lymphocytic leukemia (CLL) patients exhibit del(11q22-23) before treatment, this cohort increases to over 40% upon progression following chemoimmunotherapy. The coding sequence of the DNA damage response gene, ataxia-telangiectasia-mutated (ATM), is contained in this deletion. The residual ATM allele is frequently mutated, suggesting a relationship between gene function and clinical response. To investigate this possibility, we sought to develop and validate an assay for the function of ATM protein in these patients. SMC1 (structural maintenance of chromosomes 1) and KAP1 (KRAB-associated protein 1) were found to be unique substrates of ATM kinase by immunoblot detection following ionizing radiation. Using a pool of eight fluorescence in situ hybridization-negative CLL samples as a standard, the phosphorylation of SMC1 and KAP1 from 46 del (11q22-23) samples was analyzed using normal mixture model-based clustering. This identified 13 samples (28%) that were deficient in ATM function. Targeted sequencing of the ATM gene of these samples, with reference to genomic DNA, revealed 12 somatic mutations and 15 germline mutations in these samples. No strong correlation was observed between ATM mutation and function. Therefore, mutation status may not be taken as an indicator of ATM function. Rather, a direct assay of the kinase activity should be used in the development of therapies.

    The practicability, safety and clinical efficacy of intracavitary therapy with Re-186-colloid in patients with recurrent otitis media and paranasal sinusitis, resistant to pharmacotherapy and surgical treatment is demonstrated based on a preliminary treatment trial. Methods: the authors report on a total of 39 applications of 5-35 MBq {sup 186}Re-colloid into the tympanon and the paranasal sinuses in six patients. Biodistribution and biokinetics were studied by gamma camera imaging. Clinical success was documented 6-20 months after therapy both by patients self-evaluation and by objective rhinootological follow-up, using a four-step score from -1 to+2. Results: no serious side effects were seen. There was good to excellent clinical improvement with a mean score of +1.44 {+-} 0.5 by patients self-evaluation and by physicians scoring of +0.81 {+-} 0.9 with only negligible extracranial tracer deposition. Conclusion: this novel treatment option using intracavitary application of Re-186-colloid in chronic otitis media and sinusitis is safe and effective. The term Radio-Tympano-Sinu-Orthesis (RTSO) might be proposed analogously to the well-known radiosynoviorthesis (RSO). (orig.)

A 33-year-old male developed sudden onset of flashing lights and floaters in his right eye 3 weeks following hepatitis A, typhoid, and yellow fever vaccinations. Fundus examination and angiography confirmed the presence of multiple peripheral chorioretinal lesions. These lesions demonstrated characteristic morphologic changes over a period of 8 weeks which were consistent with a diagnosis of self-resolving multifocal choroiditis. Vaccine-induced intraocular inflammation has been described infrequently. We demonstrate the first case of self-resolving multifocal choroiditis following simultaneous administration of hepatitis A, yellow fever, and typhoid immunizations.Keywords: multifocal choroiditis, vaccination, hepatitis A, typhoid, yellow fever

    Levamisole is an anthelmintic agent and also immunostimulant drug which is used to treat colorectal cancer. The present study aimed to show accidental consumption of levamisole alone induced multifocal inflammatory leukoencephalopathy. A 53-year-old male was admitted to the Neurology Department of Farabi Hospital (Kermanshah, Iran) with walking inability and recognition disorder. Following clinical examinations, the patient diagnosed as multifocal inflammatory leukoencephalopathy following levamisole consumption.The patient was treated with intravenous methylprednisolone followed by prednisolone. The magnetic resonance imaging (MRI) was done 1 month later and did not show a reduction or remission in the lesions. History of the patient showed that he had accidentally consumed levamisole 8 months ago. It seems that the consumption of levamisole can induce multifocal inflammatory leukoencephalopathy and delayed treatment of the patient with corticosteroid cannot diminish the neurotoxicity of levamisole. In addition, the cytotoxic dose of levamisole induces irreversible multifocal inflammatory leukoencephalopathy.

    This paper presents a general approach to designing the isotropic spherical media with complex spatial structure that provide different types of imaging for different light rays. It is based on equivalence of the spherical medium and the corresponding geodesic lens. We use this approach to design multi-focal gradient- index lenses embedded into an optically homogeneous region and multi-focal absolute instruments that provide perfect imaging of three-dimensional domains.

    A nestling Derbyan parrot (Psittacula derbiana) was presented with unusual subcutaneous swellings of the thigh regions, and poor growth. Histological examination revealed actinomycetous bacteria associated with multifocal systemic granulomas. The clinical and pathological findings of the case are presented, and some relevant aspects of actinomycetous bacterial infections in mammals and birds are discussed. Although granulomatous disease is encountered at times in avian species, the actinomycetous bacteria (Nocardia and Actinomyces spp.) have rarely been reported in association with multifocal granulomatous disease in birds.

    Osteonecrosis is a well-recognized complication of corticosteroid use resulting in significant morbidity, often requiring surgical intervention. Whole-body MRI is a promising method that allows imaging of the whole patient in a reasonable time without the use of ionizing radiation. This technique has the potential for evaluating nonmalignant multifocal skeletal disease like osteonecrosis. This case highlights the value of whole-body MR in an adolescent with dermatomyositis who developed multifocal osteonecrosis. (orig.)

    Full Text Available Progressive multifocal leukoencephalopathy (PML caused by reactivation of the JC virus (JCV, a human polyomavirus, occurs in autoimmune disorders, most frequently in systemic lupus erythematosus (SLE. We describe a HIV-negative 34-year-old female with SLE who had been treated with immunosuppressant therapy (IST; steroids and azathioprine since 2004. In 2011, she developed decreased sensation and weakness of the right hand, followed by vertigo and gait instability. The diagnosis of PML was made on the basis of brain MRI findings (posterior fossa lesions and JCV isolation from the cerebrospinal fluid (700 copies/ml. IST was immediately discontinued. Cidofovir, mirtazapine, mefloquine and cycles of cytarabine were sequentially added, but there was progressive deterioration with a fatal outcome 1 year after disease onset. This report discusses current therapeutic choices for PML and the importance of early infection screening when SLE patients present with neurological symptoms. In the light of recent reports of PML in SLE patients treated with rituximab or belimumab, we highlight that other IST may just as well be implicated. We conclude that severe lymphopenia was most likely responsible for JCV reactivation in this patient and discuss how effective management of lymphopenia in SLE and PML therapy remains an unmet need.

    Multifocal epithelial hyperplasia (MEH), also known as Heck’s disease, manifests as a papulonodular lesion in the oral mucosa and has been associated with the human papillomavirus, a virus related to various precancerous diseases in the oral cavity. It has a predisposition for the female gender and for children. Although the majority of reported cases have been among American Indians and Eskimos, it has been described in multiple ethnic groups in various geographical locations. The objective of this review was to report on the clinical characteristics and epidemiology of MEH and its possible correlation with oral cancer. It is based on a search of articles in international journals published prior to April 2011, using the PubMed database and selecting articles related to the epidemiology and clinical characteristics of MEH. The review revealed a higher number of cases in individuals of American Indian origin and a predilection of the disease for the female gender and for patients between the 1st and 2nd decades of life. The most frequent lesion site was the lower lip. The disease has been associated with socio-economic and genetic factors, among others. No cases of malignant transformation have been reported.

    Full Text Available A child suffering from traumatic cataract and corneal astigmatism of 2.14 D had a phacoemulsification operation and implantation of a ReSTOR Toric intraocular lens (IOL to correct the astigmatism. The primary outcome measurements were the uncorrected distance visual acuity (UDVA, uncorrected near vision at 40 cm, intraocular pressure, spherical equivalent refraction, residual astigmatism, corneal astigmatism, presence of unusual optical phenomena, and use of spectacles. At 7 months postoperatively, UDVA was maintained between 16/20 and 24/20, near vision was between J1 and J3, residual spherical refraction was 0–0.37 D, and residual refractive cylinder was between 0 and 0.67 D. A multifocal toric IOL can provide the possibility of satisfactory vision for both distant and near conditions without the use of spectacles to meet children’s needs when studying and doing sports. Additionally, binocular vision can be reconstructed. This intervention, therefore, seems to be a satisfactory alternative.

    Images of computed tomography (CT), ultrasonography (US), angiography and radionuclide imaging were analyzed in six cases of multifocal fatty infiltration of the liver. Histologic confirmation of fatty infiltration was obtained in one patient by percutaneous biopsy. In the remaining patients, presumptive confirmation of the diagnosis was based on the CT number in one patient and partial or complete resolution of the lesions on repeat CT scans or US in 4 patients. CT and US were performed in all six patients. CT scans demonstrated multiple round areas of low attenuation within both lobes of the liver in all cases. US studies showed hyperechoic foci in three cases and diffuse inhomogeneous hyperechogenicity in three cases. Hepatic arteriograms in five cases and liver scintigrams in four cases showed evidence of space-occupying lesions. In all no cases, the lesions completely or partially resolved in follow-up CT and US, and in four cases the lesions disappeared within two months, so follow-up examinations within about 2 months are necessary to differentiate them from liver neoplasms.

    2013-01-01

    Full Text Available Purpose: To investigate changes in multifocal electroretinography (mfERG parameters associated with high dose chloroquine therapy for treatment of malaria in the Amazonia region of Brazil. Methods: Forty-eight subjects who had received chloroquine treatment for single or multiple malaria infections with a cumulative dose ranging from 1,050 to 27,000mg were included. The control group consisted of 37 healthy aged-matched subjects. Data was collected on amplitude and implicit time of the N1, P1 and N2 waves in the central macular hexagon (R1 and in five concentric rings at different retinal eccentricities (R2-R6. Results: No significant difference was observed in any mfERG parameter between chloroquine treated patients and control subjects. A comparison with previous data obtained from patients with rheumatologic disorders in the same region of Brazil who had received larger cumulative doses of chloroquine and had displayed mfERG changes, indicated that retinal toxicity seems to be dependent on cumulative dose. Conclusion: Lack of mfERG changes in the current study suggests that intensive high dose chloroquine therapy for treatment of malaria is not associated with retinal toxicity.

    Full Text Available Victoria H Lawson,1 W David Arnold1,2 1Division of Neuromuscular Disorders, Department of Neurology, 2Department of Physical Medicine and Rehabilitation, Wexner Medical Center at The Ohio State University, Columbus, Ohio, USA Abstract: Multifocal motor neuropathy (MMN is an uncommon, purely motor neuropathy associated with asymmetric deficits with predilection for upper limb involvement. Even in the early descriptions of MMN, the associations of anti-GM1 antibodies and robust response to immunomodulatory treatment were recognized. These features highlight the likelihood of an underlying autoimmune etiology of MMN. The clinical presentation of MMN can closely mimic several neurological conditions including those with more malignant prognoses such as motor neuron disease. Therefore early and rapid recognition of MMN is critical. Serological evidence of anti GM-1 antibodies and electrodiagnostic findings of conduction block are helpful diagnostic clues for MMN. Importantly, these diagnostic features are not universally present, and patients lacking these characteristic findings can demonstrate similar robust response to immunodulatory treatment. In the current review, recent research in the areas of diagnosis, pathogenesis, and treatment of MMN and needs for the future are discussed. The characteristic findings of MMN and treatment implications are reviewed and contrasted with other mimicking disorders.

    Recurrence plots display binary texture of time series from dynamical systems with single dots and line structures. Using fuzzy recurrence plots, recurrences of the phase-space states can be visualized as grayscale texture, which is more informative for pattern analysis. The proposed method replaces the crucial similarity threshold required by symmetrical recurrence plots with the number of cluster centers, where the estimate of the latter parameter is less critical than the estimate of the former.

    Spontaneous pneumothorax (PNO) is usually due to rupture of a small subpleural bleb into the pleural cavity and affects mainly young men. After simple drainage, recurrence occurs in about 50% of cases. The risk of recurrence increases after each new PNO. Secondary PNO complicates an underlying pulmonary disease, especially chronic obstructive pulmonary disease with emphysema. A new form of secondary PNO has emerged in the recent years in AIDS patients with pneumocystis carinii pneumonia. We have shifted to a thoracoscopic therapy of PNO since May 1991. 25 PNO in 24 patients (1 bilateral) have been treated since that time up to April 1993. 19 PNO were primary, whereas 6 were secondary, included 3 iatrogenic PNO. Resection of the leaking parenchymal area was performed in 20 patients, and parietal partial pleurectomy was done in 20 cases. In the remaining cases, fibrin glue was applied on the lesion and in 3 cases, chemical pleurodesis was attempted using silver nitrate or talc. 1 AIDS patient died of ARDS. 3 patients had recurrent PNO and had thoracotomy without complication. 21 patients did well. Partial PNO recurred in one of them 4 months later, and was treated by simple needle aspiration. Thoracoscopy is a useful method to treat recurrent or persistent spontaneous PNO. After only 25 cases, our success rate in primary PNO is 90%. There should be a learning curve. On the basis of our experience, we believe that recognition of the lesion and its resection as well as apical parietal pleurectomy are necessary to obtain good results and a low recurrence rate.

    Full Text Available Progressive multifocal leukoencephalopathy (PML usually occurs in patients with severe immunosuppression, hematological malignancies, chronic inflammatory conditions or receiving organ transplant. Recently, PML has also been observed in patients treated with monoclonal antibodies. By taking advantage of the availability of samples from a multiple sclerosis (MS patient treated with natalizumab, the antibody anti-α4 integrin, who developed PML and was monitored starting before therapy initiation, we investigated the fate of T and B lymphocytes in the onset of PML. Real-time PCR was used to measure new T- and B-cell production by means of T-cell receptor excision circle (TREC and K-deleting recombination excision circle (KREC analysis and to quantify transcripts for CD34, terminal-deoxynucleotidyltransferase, and V pre-B lymphocyte gene 1. T- and B-cell subsets and T-cell heterogeneity were measured by flow cytometry and spectratyping. The data were compared to those of untreated and natalizumab-treated MS patients and healthy donors. Before therapy, a patient who developed PML had a low TREC and KREC number; TRECs remained low, while KRECs and pre-B lymphocyte gene 1 transcripts peaked at 6 months of therapy and then decreased at PML diagnosis. Flow cytometry confirmed the deficient number of newly produced T lymphocytes, counterbalanced by an increase in TEMRA cells. The percentage of naive B cells increased by approximately 70% after 6 months of therapy, but B lymphocyte number remained low for the entire treatment period. T-cell heterogeneity and immunoglobulins were reduced. Although performed in a single patient, all results showed that an immune deficit, together with an increase in newly produced B cells a few months after therapy initiation, may predispose the patient to PML. These findings indicate the TREC/KREC assay is a potential tool to identify patients at risk of developing PML and may provide insights into the immunological

    Tomofusa Yamauchi

    Full Text Available PURPOSE: To compare the visual performance of multifocal intraocular lenses (IOLs and monofocal IOLs made of the same material. METHODS: The subjects included patients implanted with either Tecnis® monofocal IOLs (ZA9003 or ZCB00 or Tecnis® multifocal IOLs (ZMA00 or ZMB00 bilaterally. We conducted a retrospective study comparing the two types of IOLs. The multifocal group included 46 patients who were implanted with Tecnis® multifocal IOLs bilaterally. The monofocal group was an age- and sex-matched control group, and included 85 patients who were implanted with Tecnis® monofocal IOLs bilaterally. Lens opacity grading, the radius of corneal curvature, corneal astigmatism, axial length and the refractive status were measured preoperatively. Pupil size, ocular aberrometry, distance, intermediate and near visual acuity, contrast sensitivity with and without glare and the responses to a quality-of-vision questionnaire were evaluated pre- and postoperatively. RESULTS: The uncorrected near visual acuity was significantly better in the multifocal group, whereas both the corrected intermediate and near visual acuity were better in the monofocal group. Contrast sensitivity (with and without glare was significantly better in the monofocal group. The rate of spectacle dependency was significantly lower in the multifocal group. There were no significant differences between the two groups regarding most items of the postoperative quality-of-vision questionnaire (VFQ-25, with the exception that the patients in the monofocal group reported fewer problems with nighttime driving. CONCLUSIONS: The multifocal IOLs used in this study reduced spectacle dependency more so than monofocal IOLs and did not compromise the subjective visual function, with the exception of nighttime driving.

    2016-01-01

    In spite of relentless efforts to devise new treatment strategies, primary glioblastomas invariably recur as aggressive, therapy-resistant relapses and patients rapidly succumb to these tumors. Many therapeutic agents are first tested in clinical trials involving recurrent glioblastomas. Remarkably......, however, fundamental knowledge on the biology of recurrent glioblastoma is just slowly emerging. Here, we review current knowledge on recurrent glioblastoma and ask whether and how therapies change intra-tumor heterogeneity, molecular traits and growth pattern of glioblastoma, and to which extent...... this information can be exploited for therapeutic decision-making. We conclude that the ability to characterize and predict therapy-induced changes in recurrent glioblastoma will determine, whether, one day, glioblastoma can be contained in a state of chronic disease.Oncogene advance online publication, 4 April...

    In this study we examine the multifocal electroretinogram (mfERG) recorded from patients suffering from Leber's hereditary optic neuropathy (LHON), a degeneration of the ganglion cell and nerve fibre layers of the retina. We compared the mfERGs recorded from 11 patients with LHON, to those from 11 control subjects. The pattern ERG (PERG) was additionally performed with 9 of the patients. MfERGs were recorded and analysed using the VERIS 3.01 system with a stimulus of 103 equal-sized hexagons. For analysis, hexagons were grouped according to distance from the optic nerve head (ONH) and according to distance from the fovea. Two significant differences were found between the waveforms of the two groups: In the first order kernel, the control group showed a component around 34 ms that decreased with distance from the ONH. This component was reduced in the LHON group of subjects. In the second order (first slice) kernel, the patient group was missing features that decrease with distance from the fovea in the control group. PERG amplitudes showed a significant correlation with the amplitude of the second order mfERG kernel. The results show that the damage to ganglion cells and nerve fibres caused by LHON can be detected in mfERG recordings and indicate that activity from the inner retina can contribute significantly to first and second order waveforms.

Clinical outcomes included uncorrected near visual acuity, uncorrected distance visual acuity, visual acuity, spectacle independence, and halos. Random effects meta-analyses were conducted to compare outcomes for the different IOL types.Results: Twenty papers were identified describing 11 monofocal IOLs and 35 multifocal IOLs (19 diffractive, including 12 ReSTOR®, 14 refractive, and two accommodative patient cohorts. Multifocal and monofocal uncorrected distance visual acuity was 0.165 (0.090–0.240 and 0.093 (0.088–0.098, respectively. Compared with monofocal IOLs, multifocal IOLs produced better uncorrected near visual acuity (0.470 [0.322–0.618] versus 0.141 [0.131–0.152]; P < 0.0001, resulting in higher spectacle independence (incidence rate ratio [IRR] 3.62 [2.90–4.52]; P < 0.0001. Compared with refractive multifocal IOLs, diffractive multifocal IOLs produced a similar uncorrected distance visual acuity (0.105 [0.098–0.111] versus 0.085 [0.029–0.140]; P ≤ 0.78, not significant and better uncorrected near visual acuity (0.217 [0.118–0.317] versus 0.082 [0.067–0.098]; P < 0.0001 resulting in higher spectacle independence (IRR 1.75 [1.24–2.48]; P < 0.001.

    Full Text Available Abstract Background This retrospective study aims to determine: 1 the sensitivity of preoperative mammography (Mx and ultrasound (US, and re-reviewed Mx to detect multifocal multicentric breast carcinoma (MMBC, defined by pathology on surgical specimens, and 2 to analyze the characteristics of both detected and undetected foci on Mx and US. Methods Three experienced breast radiologists re-reviewed, independently, digital mammography of 97 women with MMBC pathologically diagnosed on surgical specimens. The radiologists were informed of all neoplastic foci, and blinded to the original mammograms and US reports. With regards to Mx, they considered the breast density, number of foci, the Mx characteristics of the lesions and their BI-RADS classification. For US, they considered size of the lesions, BI-RADS classification and US pattern and lesion characteristics. According to the histological size, the lesions were classified as: index cancer, 2nd lesion, 3rd lesion, and 4th lesion. Any pathologically identified malignant foci not previously described in the original imaging reports, were defined as undetected or missed lesions. Sensitivity was calculated for Mx, US and re-reviewed Mx for detecting the presence of the index cancer as well as additional satellite lesions. Results Pathological examination revealed 13 multifocal and 84 multicentric cancers with a total of 303 malignant foci (282 invasive and 21 non invasive. Original Mx and US reports had an overall sensitivity of 45.5% and 52.9%, respectively. Mx detected 83/97 index cancers with a sensitivity of 85.6%. The number of lesions undetected by original Mx was 165/303. The Mx pattern of breasts with undetected lesions were: fatty in 3 (1.8%; scattered fibroglandular density in 40 (24.3%, heterogeneously dense in 91 (55.1% and dense in 31 (18.8% cases. In breasts with an almost entirely fatty pattern, Mx sensitivity was 100%, while in fibroglandular or dense pattern it was reduced to 45

Materials and methods: All presbyopic (age >40 years, near add ≥+1.25 D and non-presbyopic (age ≥18 years, no near add requirements, spherical equivalent ≤-0.50 D participants were each fitted bilaterally with six and two MFCLs (test lens, respectively, and with one single vision lens (control lens. Lens decentration, ie, the x- and y-differences between the contact lens and pupil centers, was objectively determined. Third-order aberrations were measured and compared. Visual performance (high- and low-contrast acuities and several subjective variables was analyzed for any associations (Pearson’s correlation, r with MFCL decentration. Results: A total of 17 presbyopic (55.1±6.9 years and eight non-presbyopic (31.0±3.3 years participants completed the study. All lenses displayed a temporal–inferior decentration (x=-0.36±0.29 mm, y=-0.28±0.28 mm, mean ± SD. Compared to the control, a significant inferior decentration was found for the Proclear® MFCL Near lens in both groups (ypresbyopic =-0.26 mm, ynon-presbyopic =-0.70 mm and for the Proclear® MFCL Distance lens in the non-presbyopic group (ynon-presbyopic =-0.69 mm. In both groups, lens-induced vertical coma (C(3, -1 was, by at least tenfold, significantly more positive for the Proclear® MFCL Distance lens and significantly more negative for the Proclear® MFCL Near lens.

    Background and Objective The frequency of multifocal atherosclerosis (MFA) in patients with coronary heart disease (CHD) has not been thoroughly studied. The purpose of our study was to perform ultrasound screening for MFA in patients with coronary atherosclerosis and make evaluation of the sensitivity and significance of different atherosclerosis markers. Methods Using Color Dupplex Ultrasound (CDU), we studied 32 clinically healthy persons and 87 patients of the city of B with clinical data for CHD where we also performed coronarography. Results In patients with coronary atherosclerosis we found high frequency of carotid atherosclerosis (93%) and peripheral artery disease (PAD) (81%). We established verifiable thickening of the intima-media (IMT) of the common carotid artery (CCA) and common femoral artery (CFA) in patients with CHD. There is a correlation between the frequency of carotid and femoral stenoses and CHD proven by coronarography. Patients with CHD had a high relative risk to develop carotid (RR = 5) and peripheral atherosclerosis (RR=3.5) and high frequency of asymptomatic stenoses and thromboses of the internal carotid artery (86.9%) and femoral artery (78.3%), as well as aneurisms of the abdominal aorta (8.1%). Markers for CAD with high sensitivity were the atherosclerotic plaques of ICA (0.93) and CFA (0.81) as well as IMT of the CFA (0.84). Conclusions MFA are common among patients with CHD. Ultrasound diagnosis is the method of choice for simultaneous non-invasive screening of carotid, peripheral and MFA and provides sensitive markers for coronary atherosclerosis. The most sensitive and specific markers for CHD are the combination of the IMT and atherosclerotic plaques of CCA, ICA and CFA (100% sensitivity and 0.92 specificity).

    Full Text Available Levamisole is an anthelmintic agent and also immunostimulant drug which is used to treat colorectal cancer. The present study aimed to show accidental consumption of levamisole alone induced multifocalinflammatory leukoencephalopathy. A 53-year-old male was admitted to the Neurology Department of Farabi Hospital(Kermanshah, Iran with walking inability and recognition disorder. Following clinical examinations, the patient diagnosed as multifocal inflammatory leukoencephalopathy following levamisole consumption.The patient was treated with intravenous methylprednisolone followed by prednisolone. The magnetic resonance imaging (MRI was done 1 month later and did not show a reduction or remission in the lesions. History of the patient showed that he had accidentally consumed levamisole 8 months ago. It seems that the consumption of levamisole can induce multifocal inflammatory leukoencephalopathy and delayed treatment of the patient with corticosteroid cannot diminish the neurotoxicity of levamisole. In addition, the cytotoxic dose of levamisole induces irreversible multifocal inflammatory leukoencephalopathy.

We report a case of toxoplasmic CRAO and multifocal retinitis with perivascular sheathing. A healthy 83-year-old male developed left panuveitis. Funduscopic examination of the left eye showed a swollen optic disc and sheathing of the retinal artery with a dense vitreous haze and a white retinal lesion. Serum anti-toxoplasma antibodies were positive in a latex agglutination assay. Vitrectomy was performed to improve visualization of the retinal lesions and for examination of causative microorganisms. A postoperative fundus examination revealed CRAO with optic disc involvement and multifocal retinitis with perivascular sheathing. Qualitative multiplex polymerase chain reaction detected the Toxoplasma gondii B1 gene in ocular fluid from both the aqueous and vitreous humor. The presumed diagnosis of ocular toxoplasmosis was made and treatment was started with prednisone and acetylspiramycin with subsequent improvement. Two months later, the patient developed active retinochoroiditis in the left eye. After 6 weeks of anti-toxoplasma therapy, the disease involuted. Retinal vascular occlusions and multifocal retinitis with perivascular sheathing are rare in toxoplasmosis. This is the first case report of toxoplasmic CRAO and multifocal retinitis with perivascular sheathing. The diagnosis of ocular toxoplasmosis should be considered in patients with retinal artery occlusions and multifocal retinitis with perivascular sheathing associated with inflammation.Keywords: ocular toxoplasmosis, toxoplasma retinochoroiditis

    A previously healthy 11-year-old girl presented with an 8-month history of anemia and left upper quadrant abdominal pain. US examination demonstrated a 9-cm cystic mass with a fluid-fluid level in the left upper quadrant with unclear organ of origin. Abdominal MR imaging demonstrated a complex cystic mass, likely arising from the stomach. Additional T2 hyperintense submucosal lesions were identified in the gastric wall. Surgical excision confirmed the diagnosis of multifocal gastric gastrointestinal stromal tumor (GIST). MR imaging was helpful in suggesting a gastric origin of the primary mass and in demonstrating multifocal disease within the stomach. (orig.)

    A man with multifocal acquired demyelinating sensory and motor neuropathy (MADSAM), or Lewis-Sumner syndrome, presented with a progressive left lumbosacral plexus lesion resembling a neurofibroma. After 7 years he developed a left ulnar nerve lesion with conduction block in its upper segment. Treatment with intravenous immunoglobulin improved the symptoms and signs of both lesions. We conclude that inflammatory neuropathy must be considered in the differential diagnosis of peripheral nerve tumors, and that unifocal lesions may precede multifocal involvement in MADSAM by several years. In addition, we discuss the clinical features in 9 patients attending a specialist peripheral nerve clinic and review the literature.

    2015-01-01

    We optimally estimate the recurrence structure of a multivariate time series by Markov chains obtained from recurrence grammars. The goodness of fit is assessed with a utility function derived from the stochastic Markov transition matrix. It assumes a local maximum for the distance threshold of the optimal recurrence grammar. We validate our approach by means of the nonlinear Lorenz system and its linearized stochastic surrogates. Finally we apply our optimization procedure to the segmentation of neurophysiological time series obtained from anesthetized animals. We propose the number of optimal recurrence domains as a statistic for classifying an animals' state of consciousness.

    Objective: In order to study the clinical manifestation and risk factor of recurrent intracerebral hemorrhage(ICH).Methods:The 256 patients were analysed who admitted to our hospital for intracerebral hemorrhage between 1995 and 1997.The 15(5 .86%)patients had a recurrent ICH.There were 9 men and 6 women and the mean age of the patients was 63.5 ± 6.4years at the first bleeding episode and 67.8± 8. 5 years at the second. The mean interval between the two bleeding episodes was 44.6 ± 12.5 months. The 73.3%patients were hypertensive .′The site of the first hemorrhage was ganglionic in 8 patients , ]ohar in six paients and brainstem in one .The recurrent hemorrhage occurred at a different location from the previous ICH.The most common pattern of recurrence was “ganglionic -ganglionic” (7 patients), lobar - ganglionic (3 patients), lobar-lobar(three patients), which was always observed in hypertensive patients. The outcome after the recurrent hemorrhage was usually poor. By comparison with 24 patients followed up to average 47.5± 18.7 months with isolated ICH without recurrence .Only lobar hematoma and a younger age were risk factors for recurrences whereas sex and previous hypertension were not. The mechanism of recurrence of ICH were multiple(hypertension, cerebral amyloid angiopathy).Contral of blood pressure and good living habit after the first hemorrhage may prevent ICH recurrences.

During IOL implantation in the left eye, the optic was unintentionally reversed in the bag and left that way. The refraction surprise was not significant and six months postoperatively the corrected distance visual acuity in both eyes was 20/20 and neither complained of visual discomfort. In conclusion, we found that a reversed-optic Tecnis multifocal IOL in the present case resulted in good final visual acuity without significant differences in aberrations compared to the other eye, and a conservative management can be taken as a safe option.Paciente de 51 anos, sexo feminino, apresentando catarata foi submetida a cirurgia de facoemulsificação com implante de lente intraocular (LIO multifocal Tecnis ZM900 em ambos os olhos (AO. Durante a implantação da LIO no olho esquerdo, a lente foi inadvertidamente implantada invertida e deixada dessa maneira. Seis meses pós-operatório a surpresa refracional não se mostrou significativa e a acuidade visual corrigida era de 20/20 em AO, sem nenhuma queixa de desconforto visual. Em conclusão, no presente caso, o implante de uma LIO Tecnis multifocal invertida resultou em boa acuidade visual final e sem diferenças significativas na aberrometria em comparação ao olho contralateral, tendo sido possível conduzir o caso de maneira conservadora.

    2011-09-01

    A typical recurrent event dataset consists of an often large number of recurrent event processes, each of which contains multiple event times observed from an individual during a follow-up period. Such data have become increasingly available in medical and epidemiological studies. In this article, we introduce novel procedures to conduct second-order analysis for a flexible class of semiparametric recurrent event processes. Such an analysis can provide useful information regarding the dependence structure within each recurrent event process. Specifically, we will use the proposed procedures to test whether the individual recurrent event processes are all Poisson processes and to suggest sensible alternative models for them if they are not. We apply these procedures to a well-known recurrent event dataset on chronic granulomatous disease and an epidemiological dataset on meningococcal disease cases in Merseyside, United Kingdom to illustrate their practical value.

    This report describes a case of bone involvement by epithelioid sarcoma, which on imaging had the appearance of a primary intraosseous lesion of the scapula. The tumor initially presented as a subcutaneous nodule which was mistakenly diagnosed as ''fibrosis'' following initial resection. The lesion recurred locally and after several resections presented with several ulcerated subcutaneous nodules, at which time all imaging studies were performed. The patient was treated with en bloc upper humeral interscapulothoracic resection and shoulder reconstruction. Two years after the operation the patient is alive without local recurrence or metastasis. (orig.)

    Primary melanocytic tumors of the central nervous system are rare. In this article the authors describe a case of C1C2 intradural extramedullary melanocytoma in a 43-year-old patient who presented with neck pain. C1-3 laminectomy was performed followed by excision of the lesion and an adjoining satellite nodule, along with the dural attachment. The histopathological features were consistent with a meningeal melanocytoma despite the presence of a satellite nodule. The patient has no evidence of recurrence during the six month follow up period. A brief review of literature pertaining to the radiological features, pathological findings, management and prognosis of this rare tumor is discussed.

    A 58-year old female with a four-year history of previously untreated CLL at Binet stage A complained about word finding problems, impaired vision, and gait unsteadiness. Concerning her CLL she was asymptomatic and had never required any specific treatment. Her neurological examination disclosed cognitive alterations, homonyme hemianopia to the right, aphasia, and mild right-sided hemiparesis. Cerebral MRI showed a hyperintense lesion on T2 weighted images without contrast enhancement. CSF examination revealed normal findings, including CSF protein, cell count, cytology and PCR-analysis was negative for the presence of JC virus DNA. On follow-up MRI, performed 2 weeks later, the T2 lesion was further enlarging. Subsequent stereotactic brain biopsy was diagnostic for PML revealing abnormal oligodendrocytes staining positive against antibodies specific for simian vacuolating virus 40. In addition, repeated CSF analyses for JC-Virus DNA in the course of the disease became positive. After confirmation of diagnosis treatment with mirtazapine (30 mg/d) and mefloquine (250 mg/d) was initiated. Rapid clinical progression correlated to further worsening on MRI. Therefore this treatment was terminated after 16 days and the regime was changed to a five-day courses of cytarabine (2 mg/kg/d) combined with intrathecal administration of liposomal cytarabine (50 mg). Due to further clinical progression with global aphasia, blindness and severe right-sided hemiparesia, medication was stopped. The Patient died three and a half months after onset of symptoms.

    Full Text Available Purpose: To evaluate wavefront performance and modulation transfer function (MTF in the human eye after the implantation of diffractive or refractive multifocal intraocular lenses (IOLs. Materials and Methods: This was a prospective, interventional, comparative, nonrandomized clinical study. Uncorrected distance and near visual acuity, and wavefront analysis including MTF curves (iTrace aberrometer, Tracey Technologies, Houston, TX, USA were measured in 60 patients after bilateral IOL implantation with 6 months of follow-up. Forty eyes received the diffractive ReSTOR (Alcon, 40 eyes received the refractive ReZoom (Advanced Medical Optics and 40 eyes, the Tecnis ZM900 (Advanced Medical Optics. The comparison of MTF and aberration between the intraocular lenses was performed using analysis of variance (ANOVA, followed by the Dunn test when necessary. Results: The mean uncorrected distance visual acuity was similar in all three groups of multifocal IOLs. The ReSTOR group provided better uncorrected near visual acuity than the ReZoom group ( P < 0.001, but similar to the Tecnis group. Spherical aberration was significantly higher in the ReZoom group ( P = 0.007. Similar MTF curves were found for the aspheric multifocal IOL Tecnis and the spheric multifocal IOL ReSTOR, and both performed better than the multifocal IOL ReZoom in a 5 mm pupil ( P < 0.001 at all spatial frequencies. Conclusions: Diffractive IOLs studied presented similar MTF curves for a 5 mm pupil diameter. Both diffractive IOLs showed similar spherical aberration, which was significantly better with the full-diffractive IOL Tecnis than with the refractive IOL ReZoom.

Methods: A single-blinded crossover trial was conducted. Twenty patients with mild presbyopia (add ≤+1.25 D and 22 with moderate/severe presbyopia (add ≥+1.50 D who wore lenses bilaterally for 1 h, with a minimum overnight washout period between the use of each lens. Measurements included high- and low-contrast visual acuity (HCVA and LCVA, respectively at a distance, contrast sensitivity (CS at a distance, HCVA at intermediate (70 cm and near (50 cm & 40 cm distances, stereopsis, and subjective questionnaires regarding vision clarity, ghosting, overall vision satisfaction, and comfort. The test variables were compared among the lens types using repeated-measures ANOVA. Results: Distance variables (HCVA, LCVA, and CS were significantly worse with multifocal lens than with AOSV lens (p≤0.008, except for AOMF lens in the mild presbyopia group in which no significant difference was observed (p>0.05. Multifocal lenses had significantly greater HCVA at 40 cm than AOSV lens (p≤0.026. AOMF lens had greater intermediate HCVA than AOP lens (p0.05. The proportions of patients willing to buy AOSV, AOMF, and AOP lenses were 20%, 40%, and 50%, respectively, in the mild presbyopia group and 14%, 32%, and 23%, respectively, in the moderate/severe presbyopia group; however, these differences were not statistically significant (p≥0.159. Conclusions: Further development of multifocal lenses is required before significant advantages of multifocal lenses over single vision lens are observed in patients with presbyopia.

    Recurrent AKI is common among patients after hospitalized AKI and is associated with progressive CKD. In this study, we identified clinical risk factors for recurrent AKI present during index AKI hospitalizations that occurred between 2003 and 2010 using a regional Veterans Administration database in the United States. AKI was defined as a 0.3 mg/dl or 50% increase from a baseline creatinine measure. The primary outcome was hospitalization with recurrent AKI within 12 months of discharge from the index hospitalization. Time to recurrent AKI was examined using Cox regression analysis, and sensitivity analyses were performed using a competing risk approach. Among 11,683 qualifying AKI hospitalizations, 2954 patients (25%) were hospitalized with recurrent AKI within 12 months of discharge. Median time to recurrent AKI within 12 months was 64 (interquartile range 19-167) days. In addition to known demographic and comorbid risk factors for AKI, patients with longer AKI duration and those whose discharge diagnosis at index AKI hospitalization included congestive heart failure (primary diagnosis), decompensated advanced liver disease, cancer with or without chemotherapy, acute coronary syndrome, or volume depletion, were at highest risk for being hospitalized with recurrent AKI. Risk factors identified were similar when a competing risk model for death was applied. In conclusion, several inpatient conditions associated with AKI may increase the risk for recurrent AKI. These findings should facilitate risk stratification, guide appropriate patient referral after AKI, and help generate potential risk reduction strategies. Efforts to identify modifiable factors to prevent recurrent AKI in these patients are warranted.

    Most angioedemas are histaminergic and correspond to deep urticarial swelling. Recurrent histaminergic angioedema led to the diagnosis of chronic urticaria, even when there are no superficial associated hives. Chronic urticaria is a benign disease, and autoimmune in 40 % of cases. The occurrence of angioedema in chronic urticaria is not a sign of severity. The occurrence of angioedema in chronic urticaria is associated with a longer duration of urticarial disease. NSAIDs and/or systemic corticotherapy are classic triggers of angioedema in chronic urticaria. In the absence of clinical endpoints, there is no need to make further assessment in chronic urticaria good responders to antihistamines.

  15. The hemolytic component of cancer anemia: effects of osmotic and metabolic stress on the erythrocytes of rats bearing multifocal inoculations of the Walker 256 tumor

    Full Text Available Cancer anemia is classified as an anemia of chronic diseases, although it is sometimes the first symptom of cancer. Cancer anemia includes a hemolytic component, important in the terminal stage when even transfused cells are rapidly destroyed. The presence of a chronic component and the terminal complications of the illness limit studies of the hemolytic component. A multifocal model of tumor growth was used here to simulate the terminal metastatic dissemination stage (several simultaneous inoculations of Walker 256 cells. The hemolytic component of anemia began 3-4 days after inoculation in 100% of the rats and progressed rapidly thereafter: Hb levels dropped from 14.9 ± 0.02 to 8.7 ± 0.06 from days 7 to 11 (~5 times the physiologically normal rate in rats in the absence of bleeding. The development of anemia was correlated (r2 = 0.86 with the development of other systemic effects such as anorexia. There was a significant decrease in the osmotic fragility of circulating erythrocytes: the NaCl concentration causing 50% lysis was reduced from 4.52 ± 0.06 to 4.10 ± 0.01 (P<0.01 on day 7, indicating a reduction in erythrocyte volume. However, with mild metabolic stress (4-h incubation at 37oC, the erythrocytes showed a greater increase in osmotic fragility than the controls, suggesting marked alteration of erythrocyte homeostasis. These effects may be due to primary plasma membrane alterations (transport and/or permeability and/or may be secondary to metabolic changes. This multifocal model is adequate for studying the hemolytic component of cancer anemia since it is rapid, highly reproducible and causes minimal animal suffering.

    2013-01-01

    Two special Finsler spaces have been introduced and investigated, namely $R^h$-recurrent Finsler space and consircularly recurrent Finsler space. The defining properties of these spaces are formulated in terms of the first curvature tensor of Cartan connection. The following three results constitute the main object of the present paper: 1. A concircularly flat Finsler manifold is necessarily of constant curvature (Theorem A); 2. Every $R^h$-recurrent Finsler manifold is concirculaly recurrent with the same recurrence form (Theorem B); 3. Every horizontally integrable concircularly recurrent Finsler manifold is $R^h$-recurrent with the same recurrence form (Theorem C). The whole work is formulated in a coordinate-free form.

    The influence of predictors for recurrence in relation to recurrence-free survival was analyzed retrospectively in differentiated thyroid cancer (DTC) patients under 21 years of age who underwent primary surgical treatment and who had a pathological diagnosis of DTC between 1983 and 2012 at Fudan University Cancer Hospital. Recurrences were retrospectively analyzed using a Cox regression model for the hazard ratio (HR) according to the clinicopathological features. A meta-analysis was performed with respect to the potential predictors for recurrence from current related studies. In the present study, there were 146 young patients aged from 7 to 20 years, with a female/male ratio of 2.65/1. Female gender was the only factor significantly associated with recurrence according to univariate (HR = 2.812, P = 0.037) and multivariate (HR = 4.107, P = 0.024) Cox regression analyses. Meta-analyses revealed that multifocality (HR = 1.91, P < 0.05) and presentation at diagnosis (HR = 1.39, P < 0.05) were highly associated with recurrence in young DTC patients. However, female gender and other factors, such as age (≤10 vs. 11-20 years), PTC (PTC vs. FTC), extrathyroidal extension, lymph node metastasis, total thyroidectomy (total vs. less than total), radioiodine therapy, and radiation history, were not associated with recurrence in young DTC patients. In conclusion, multifocality and presentation at diagnosis are strong predictive factors of recurrence in relation to recurrence-free survival. We recommend studies with larger sample sizes and longer follow-up to verify the influence of predictors for disease recurrence in young patients.

    The transitions from or to strange nonchaotic attractors are investigated by recurrence plot-based methods. The techniques used here take into account the recurrence times and the fact that trajectories on strange nonchaotic attractors (SNAs) synchronize. The performance of these techniques is shown for the Heagy-Hammel transition to SNAs and for the fractalization transition to SNAs for which other usual nonlinear analysis tools are not successful.

    The aim of this study was to determine the presence of organization of atrial activation processes during atrial fibrillation (AF) by assessing whether the activation sequences are wholly random or are governed by deterministic mechanisms. We performed both linear and nonlinear analyses based on the cross correlation function (CCF) and recurrence plot quantification (RPQ), respectively. Recurrence plots were quantified by three variables: percent recurrence (PR), percent determinism (PD), and entropy of recurrences (ER). We recorded bipolar intra-atrial electrograms in two atrial sites during chronic AF in 19 informed subjects, following two protocols. In one, both recording sites were in the right atrium; in the other protocol, one site was in the right atrium, the other one in the left atrium. We extracted 19 episodes of type I AF (Wells' classification). RPQ detected transient recurrent patterns in all the episodes, while CCF was significant only in ten episodes. Surrogate data analysis, based on a cross-phase randomization procedure, decreased PR, PD, and ER values. The detection of spatiotemporal recurrent patterns together with the surrogate data results indicate that during AF a certain degree of local organization exists, likely caused by deterministic mechanisms of activation.

    Full Text Available Endobronchial involvement of extrapulmonary malignant tumors is uncommon and mostly associated with breast, kidney, colon, and rectum carcinomas. A 68-year-old male with a prior diagnosis of colon non-Hodgkin lymphoma (NHL was admitted to the hospital with a complaint of cough, sputum, and dyspnea. The chest radiograph showed right hilar enlargement and opacity at the right middle zone suggestive of a mass lesion. Computed tomography of thorax revealed a right-sided mass lesion extending to thoracic wall with the destruction of the third and the fourth ribs and a right hilar mass lesion. Fiberoptic bronchoscopy was performed in order to evaluate endobronchial involvement and showed stenosis with mucosal tumor infiltration in right upper lobe bronchus. The pathological examination of bronchoscopic biopsy specimen reported diffuse large B-cell lymphoma and the patient was accepted as the endobronchial recurrence of sigmoid colon NHL. The patient is still under treatment of R-ICE (rituximab-ifosfamide-carboplatin-etoposide chemotherapy and partial regression of pulmonary lesions was noted after 3 courses of treatment.

    2016-01-01

    Idiopathic hypertrophic spinal pachymeningitis (IHSP) is a chronic progressive and diffuse inflammatory fibrosis of the spinal dura mater. Though treatment of IHSP is surgical decompression with steroid therapy, treatment for recurrent IHSP is controversial. Our patient was diagnosed with IHSP based on magnetic resonance imaging (MRI) and underwent laminectomy for decompression following steroid pulse therapy. Despite maintenance of steroid therapy, the patient experienced 3 recurrences. As an alternative immunosuppressant medication, methotrexate was introduced with low-dose steroid. Fortunately, the symptom was resolved, and a decrease of dura thickening was revealed on MRI. We present the case and suggest that methotrexate might be an effective treatment modality for recurrent IHSP.

    Multifocal stenosing enteritis, not related to Crohn's disease or drug intake, has been described under two different terms: "cryptogenic multifocal ulcerous stenosing enteritis" (CMUSE) and "neuromuscular and vascular hamartoma" (NMVH). We present three new cases of this condition and argue that the two terms reflect the same disease entity. Although etiology and pathogenesis of the disease remain largely unclear, obliterative vascular changes may play an important role.

    Medulloblastoma (MB), the most common malignant tumor typically affecting children, occurs only exceptionally in adults. Multifocal presentation of this malignancy in adulthood is even much rarer—only four cases with favorable postoperative course have been reported, so far. The study illustrates a very rare rapid postoperative clinical deterioration due to diffuse cerebellar swelling (DCS) in an adult multifocal MB (MMB). To the best of their knowledge, authors for the first time performed genetic analysis of MMB and demonstrated expression patterns of selected markers that put the patient within the sonic hedgehog (SHH) molecular subgroup and at least partially explain her unsatisfactory clinical course. Herein, authors summarized the relevant literature concerning this issue with the aim to determine features that would facilitate diagnosis and therapy of such a scarce clinical entity.

    The AcrySof ReSTOR intraocular lens (IOL) is a multifocal lens with state-of-the-art apodized diffractive technology, and is indicated for visual correction of aphakia secondary to removal of cataractous lenses in adult patients with/without presbyopia, who desire near, intermediate, and distance vision with increased spectacle independence. The multifocal design results in some optical contrast reduction, which may be improved by reducing spherical aberration. A novel patent-pending approach was undertaken to investigate the optical performance of aspheric lens designs. Simulated eyes using human normal distributions were corrected with different lens designs in a Monte Carlo simulation that allowed for variability in multiple surgical parameters (e.g. positioning error, biometric variation). Monte Carlo optimized results indicated that a lens spherical aberration of -0.10 microm provided optimal distance image quality.

    Full Text Available A 51-year-old woman with age-related cataract had an uneventful phacoemulsification and a Tecnis ZM900 multifocal intraocular lens (IOL implantation in both eyes. During IOL implantation in the left eye, the optic was unintentionally reversed in the bag and left that way. The refraction surprise was not significant and six months postoperatively the corrected distance visual acuity in both eyes was 20/20 and neither complained of visual discomfort. In conclusion, we found that a reversed-optic Tecnis multifocal IOL in the present case resulted in good final visual acuity without significant differences in aberrations compared to the other eye, and a conservative management can be taken as a safe option.

    Full Text Available Brucellosis is a zoonosis that can affect many organs or systems. Musculoskeletal system is the most commonly affected site in brucellosis and the frequency of musculoskeletal system involvement varies between 2% and 53%. Multifocal spinal involvement is rare. Here, it was aimed to present our case with brucellar spondylodiscitis involving the thoracic and lumbar regions simultaneously. MRI is a useful imaging method in the diagnosis of multifocal spinal infection caused by brucellosis. Especially in endemic regions, at least two serological tests should be used in the diagnosis of brucellosis. Brucellosis should be absolutely kept in mind for the differential diagnosis of the lderly patients with complaint of longstanding thoracic and back pain in the regions where brucellosis is endemic.

    Full Text Available Radioiodine (RAI has played a crucial role in differentiated thyroid cancer treatment for more than 60years. However, the use of RAI administration in patients with papillary thyroid microcarcinoma (even multifocal is now being widely discussed and often not recommended. In accordance with European consensus, and contrary to the American Thyroid Association (ATA guidelines, we recently performed RAI thyroid remnant ablation in a patient with differentiated papillary multifocal microcarcinoma. The post-therapeutic whole-body scan and SPECT/CT revealed the real and unexpected extent of disease, with metastases to upper mediastinal lymph nodes. This finding led to the patient’s upstaging from stage I to stage IVa according to the American Joint Committee on Cancer/International Union Against Cancer criteria.

    2016-03-01

    Full Text Available Children presenting with recurrent fever may represent a diagnostic challenge. After excluding the most common etiologies, which include the consecutive occurrence of independent uncomplicated infections, a wide range of possible causes are considered. This article summarizes infectious and noninfectious causes of recurrent fever in pediatric patients. We highlight that, when investigating recurrent fever, it is important to consider age at onset, family history, duration of febrile episodes, length of interval between episodes, associated symptoms and response to treatment. Additionally, information regarding travel history and exposure to animals is helpful, especially with regard to infections. With the exclusion of repeated independent uncomplicated infections, many infective causes of recurrent fever are relatively rare in Western countries; therefore, clinicians should be attuned to suggestive case history data. It is important to rule out the possibility of an infectious process or a malignancy, in particular, if steroid therapy is being considered. After excluding an infectious or neoplastic etiology, immune-mediated and autoinflammatory diseases should be taken into consideration. Together with case history data, a careful physical exam during and between febrile episodes may give useful clues and guide laboratory investigations. However, despite a thorough evaluation, a recurrent fever may remain unexplained. A watchful follow-up is thus mandatory because new signs and symptoms may appear over time.

    Children presenting with recurrent fever may represent a diagnostic challenge. After excluding the most common etiologies, which include the consecutive occurrence of independent uncomplicated infections, a wide range of possible causes are considered. This article summarizes infectious and noninfectious causes of recurrent fever in pediatric patients. We highlight that, when investigating recurrent fever, it is important to consider age at onset, family history, duration of febrile episodes, length of interval between episodes, associated symptoms and response to treatment. Additionally, information regarding travel history and exposure to animals is helpful, especially with regard to infections. With the exclusion of repeated independent uncomplicated infections, many infective causes of recurrent fever are relatively rare in Western countries; therefore, clinicians should be attuned to suggestive case history data. It is important to rule out the possibility of an infectious process or a malignancy, in particular, if steroid therapy is being considered. After excluding an infectious or neoplastic etiology, immune-mediated and autoinflammatory diseases should be taken into consideration. Together with case history data, a careful physical exam during and between febrile episodes may give useful clues and guide laboratory investigations. However, despite a thorough evaluation, a recurrent fever may remain unexplained. A watchful follow-up is thus mandatory because new signs and symptoms may appear over time.

    Purpose The aim of this study was to assess visual and refractive outcomes of laser vision correction (LVC) to correct residual refraction after multifocal intraocular lens (IOL) implantation. Patients and methods In this retrospective study, 782 eyes that underwent LVC to correct unintended ametropia after multifocal IOL implantation were evaluated. Of all multifocal lenses implanted during primary procedure, 98.7% were refractive and 1.3% had a diffractive design. All eyes were treated with VISX STAR S4 IR excimer laser using a convectional ablation profile. Refractive outcomes, visual acuities, patient satisfaction, and quality of life were evaluated at the last available visit. Results The mean time between enhancement and last visit was 6.3±4.4 months. Manifest spherical equivalent changed from −0.02±0.83 D (−3.38 D to +2.25 D) pre-enhancement to 0.00±0.34 D (−1.38 D to +1.25 D) post-enhancement. At the last follow-up, the percentage of eyes within 0.50 D and 1.00 D of emmetropia was 90.4% and 99.5%, respectively. Of all eyes, 74.9% achieved monocular uncorrected distance visual acuity 20/20 or better. The mean corrected distance visual acuity remained the same before (−0.04±0.06 logMAR [logarithm of the minimum angle of resolution]) and after LVC procedure (−0.04±0.07 logMAR; P=0.70). There was a slight improvement in visual phenomena (starburst, halo, glare, ghosting/double vision) following the enhancement. No sight-threatening complications related to LVC occurred in this study. Conclusion LVC in pseudophakic patients with multifocal IOL was safe, effective, and predictable in a large cohort of patients. PMID:27175059

  18. Multifocal fibrosing thyroiditis: report of 55 cases of a poorly recognized entity.

    Science.gov (United States)

    Fellegara, Giovanni; Rosai, Juan

    2015-03-01

    During the course of our consultation activity, we have recognized a peculiar form of thyroiditis in which multiple foci of fibrosis, most of which were associated with reactive atypia of the surrounding follicles, are present. We have referred to this condition, both in our consultation reports and in the third series of A.F.I.P. Fascicle on Tumors of the Thyroid Gland, as "multifocal fibrosing thyroiditis" or (less frequently) "multifocal sclerosing thyroiditis," which are descriptive terms that highlight the benign/inflammatory nature of the process, its multiplicity, and its unknown pathogenesis. The aim of this study is to better define the morphologic features of this process and correlate it with some clinical data. With this purpose, the consultation files of one of the authors (J.R.) were searched for cases coded as multifocal fibrosing thyroiditis or multifocal sclerosing thyroiditis in a 20-year period ranging from January 1989 to December 2009. A total of 55 cases were identified that displayed the above-listed features. There were 51 (93%) female and 4 (7%) male patients (F/M=12.75), with ages ranging between 15 and 71 years (mean age, 47.03 y; median age, 44.5 y). Microscopically, multiple foci of fibrosis were identified in all cases, their number ranging from 2 to 51 per case (mean number, 16), with a mean diameter of 3 mm (range: 0.36 to 15.1 mm). Although heterogenous in shape and size, the individual foci were rather similar to each other in composition, being characterized by a fibrotic poorly cellular center that merged with a cellular peripheral zone. Some of the follicular structures present at the periphery of the scar and-to a lesser extent-those entrapped inside it underwent complex reactive and regenerative (atypical) changes that simulated malignancy. We discuss the differential diagnosis with other benign and malignant thyroid conditions and speculate about its pathogenesis and possible relationship with papillary thyroid microcarcinoma.

    Full Text Available Purpose. This study retrospectively analyzed the postoperative visual functions of myopic eyes implanted with multifocal intraocular lens (IOL to evaluate the efficacy of multifocal IOL in highly myopic eyes. Methods. We studied 61 patients (96 eyes who were implanted with multifocal IOL ZMA00 or ZMB00 (Abbott Medical Optics. The patients were stratified into two groups by axial length: 26 mm or above (AL≥26 group and below 26 mm (AL<26 group. Postoperative corrected and uncorrected distance (5 m and near (30 cm visual acuity (VA, contrast sensitivity, and depth of focus were compared between two groups. Results. In the AL≥26 group and the AL<26 group, the mean ± standard deviation uncorrected distance logMAR VA at 12-month postoperative follow-up was -0.04±0.11 and -0.01±0.14, respectively; and the corrected distance VA was -0.17±0.08 and -0.14±0.07, with no significant differences between two groups (p=0.558 and 0.101; Mann-Whitney U test. For near VA, the corresponding uncorrected VA was 0.06±0.08 and 0.05±0.09; and distance-corrected VA was 0.01±0.06 and 0.01±0.02, with no significant differences between two groups (p=0.572, and 0.157; Mann-Whitney U test. Conclusion. The present study demonstrates that it is possible to achieve good uncorrected near and distance VA following implantation of multifocal IOL in eyes with long axial lengths.

    Coexistent breast malignancy arising in phyllodes tumor is extremely rare, and most of them are incidental reports after surgical excision. Coexistent malignancy in phyllodes tumor can vary from in-situ to invasive carcinoma. Lobular neoplasia is separated into atypical lobular hyperplasia and lobular carcinoma in situ (LCIS). LCIS is known to have a higher risk of developing invasive cancer. We reported imaging findings of multifocal LCIS arising in benign phyllodes tumor.

    Meningeal melanocytoma is a rare benign CNS tumor derived from the leptomeningeal melanocytes. Although unusual, malignant transformation with leptomeningeal seeding into the brain or spinal cord may occur years after the initial diagnosis. The authors report a unique case of multifocal benign meningeal melanocytoma involving both cerebellopontine angles and the thoracic spinal cord, with associated diffuse leptomeningeal hyperpigmentation. They review the literature relevant to this topic and discuss the radiological and pathological features of this disease as well as its treatment options.

    Castleman's disease is an uncommon lymphoproliferative disorder characterized by lymph node enlargement, hyperplasia of lymphoid follicles surrounded by mature lymphocytes, and capillary proliferation with endothelial hyperplasia. Although intracranial location is very uncommon, it should be considered in the differential diagnosis of meningeal tumors. We describe a new case appearing as two solid extraaxial masses simulating meningiomas. This multifocal meningeal involvement can be considered as an exceptional form of presentation of intracranial Castleman's disease.

In the previous four patients treated with cidofovir the outcome was discouraging, as was the case in this patient.

  7. N-3 Polyunsaturated Fatty Acids of Marine Origin and Multifocality in Human Breast Cancer.

    Directory of Open Access Journals (Sweden)

    Lobna Ouldamer

    Full Text Available The microenvironment of breast epithelial tissue may contribute to the clinical expression of breast cancer. Breast epithelial tissue, whether healthy or tumoral, is directly in contact with fat cells, which in turn could influence tumor multifocality. In this pilot study we investigated whether the fatty acid composition of breast adipose tissue differed according to breast cancer focality.Twenty-three consecutive women presenting with non-metastatic breast cancer underwent breast-imaging procedures including Magnetic Resonance Imaging prior to treatment. Breast adipose tissue specimens were collected during breast surgery. We established a biochemical profile of adipose tissue fatty acids by gas chromatography. We assessed whether there were differences according to breast cancer focality.We found that decreased levels in breast adipose tissue of docosahexaenoic and eicosapentaenoic acids, the two main polyunsaturated n-3 fatty acids of marine origin, were associated with multifocality.These differences in lipid content may contribute to mechanisms through which peritumoral adipose tissue fuels breast cancer multifocality.

    To evaluate the effect of chlorogenic acid supplementation in patients with retinitis pigmentosa, we evaluated objective change in visual function with multifocal electroretinography, along with visual acuity, visual field, standard electroretinography, and contrast sensitivity. Eighteen patients diagnosed with retinitis pigmentosa were enrolled in this prospective, non-comparative, single-arm study. Multifocal electroretinography, best-corrected visual acuity in Early Treatment Diabetic Retinopathy Study letters, total point score on visual field examination with Humphrey Field Analyzer II, electroretinography, and contrast sensitivity were measured and repeated after 3 months supplementation with chlorogenic acid. The amplitude of ring 5 was significantly higher on multifocal electroretinography after 3 months of chlorogenic acid supplementation (7.2 ± 9.5 vs 8.3 ± 10.8 nV/deg(2), mean ± standard deviation, P = 0.022). There were no significant changes in the best-corrected visual acuity, total point score on Humphrey Field Analyzer, 30 Hz flicker amplitude on standard electroretinography, or contrast sensitivity. Chlorogenic acid may have a beneficial effect on the peripheral area at the margins of retinal degeneration, and should be considered as an anti-oxidant for the management of retinitis pigmentosa.

    Recurrent wheezing have a significant morbidity and it’s estimated that about one third of school-age children manifest the symptom during the first 5 years of life. Proper identification of children at risk of developing asthma at school age may predict long-term outcomes and improve treatment and preventive approach, but the possibility to identify these children at preschool age remains limited. For many years authors focused their studies to identify early children with recurrent wheezing at risk to develop asthma at school age. Different phenotypes have been proposed for a more precise characterization and a personalized plan of treatment. The main criticism concerns the inability to define stable phenotypes with the risk of overestimating or underestimating the characteristics of symptoms in these children. The aim of this review is to report the recent developments on the diagnosis and treatment of recurrent paediatric wheezing. PMID:26835404

    1988-08-01

    The incidence of recurrence of angular cheilitis following a successful antimicrobial treatment was studied in 48 patients. Clinical assessments including a microbial examination were carried out 8 months and 5 yr after termination of treatment. Eighty percent of the patients reported recurrence of their angular cheilitis on one or more occasions during the observation period. Patients with cutaneous disorders associated with dry skin or intraoral leukoplakia had an increased incidence of recrudescence. Neither the presence of denture stomatitis nor the type of microorganisms isolated from the original lesions of angular cheilitis, i.e. Candida albicans and/or Staphylococcus aureus, were associated with the number of recurrences. The present observations indicate that treatment of the majority of patients with angular cheilitis should be considered in a longer perspective than previously supposed, due to the short lasting therapeutic effects of the antimicrobial therapy.

  12. Recurrent Novae - A Review

    Mukai, Koji

    2014-01-01

    In recent years, recurrent nova eruptions are often observed very intensely in wide range of wavelengths from radio to optical to X-rays. Here I present selected highlights from recent multi-wavelength observations. The enigma of T Pyx is at the heart of this paper. While our current understanding of CV and symbiotic star evolution can explain why certain subset of recurrent novae have high accretion rate, that of T Pyx must be greatly elevated compared to the evolutionary mean. At the same time, we have extensive data to be able to estimate how the nova envelope was ejected in T Pyx, and it turns to be a rather complex tale. One suspects that envelope ejection in recurrent and classical novae in general is more complicated than the textbook descriptions. At the end of the review, I will speculate that these two may be connected.

    Full Text Available Background: Careful hepatocellular carcinoma (HCC case selection permits orthotopic liver transplantation with the expectation of around 70% plus 5-year survival. However, many patients have tumor recurrences and there is little literature guidance in the management of these patients. Aims: A retrospective examination of patients transplanted with HCC who subsequently developed liver recurrence. Methods: A case cohort series of patients was prospectively followed who had liver-only multifocal tumor recurrence of HCC after liver transplant and were then treated with chemoembolization. Results: All 6 patients had recurrent HCC. 2 had no response, 1 had stable disease, 2 had partial response (PR and 1 had complete disappearance (CR of disease. Their survival (in months was: 13 (no response, 18 (no response, 12 (stable disease, 19 (PR, 30 (PR and 50 (CR. There were no liver toxicities. Conclusions: Chemoembolization for tumor recurrence in the transplanted liver is as safe as or safer than in the pre-transplant liver, due to the absence of cirrhosis. In this series, there were 3 of 6 responses with some long survivors.

    Full Text Available Recurrent parotitis is an uncommon condition in children. Its etiological factors have not been proved till date although causes due to genetic inheritance, local autoimmune manifestation, allergy, viral infection and immunodeficiency have been suggested. The exact management of this disorder is not yet standardized, but a conservative approach is preferred and all affected children should be screened for Sjogren′s syndrome and immune deficiency including human immunodeficiency virus. We report a 12 years female child who presented with 12 episodes of non-painful recurrent swellings of the bilateral parotid gland in the past 3 years.

    There was remarkable progress in the understanding of the role genetic risk factors in chronic pancreatitis.These factors seem to be much more important than thought in the past.The rare autosomal-dominant mutations N29I and R122H of PRSS1(cationic trypsinogen) as well as the variant N34S of SPINK1(pancreatic secretory trypsin inhibitor) are associated to a disease onset in childhood or youth.Compared to chronic alcoholic pancreatitis the progression is slow so that for a long time only signs of acute-recurrent pancreatitis are found.Only at later time points(more than 10-15 years) there is evidence for chronic pancreatitis in the majority of patients.Acute recurrent pancreatitis may therefore be regarded as a transition state until definite signs of chronic pancreatitis are detectable.

    Mechanical small bowel obstructions caused by gallstones account for 1% to 3% of cases. In these patients, 80% to 90% of residual gallstones in these patients will pass through a remaining fistula without consequence. Recurrent gallstone ileus has been reported in 5% of patients. We report the case of a woman, aged 72 years, who presented with mechanical small bowel obstruction caused by gallstone ileus. After successful surgical therapy for gallstone ileus, the patient's symptoms recurred, and she was diagnosed with recurrent gallstone ileus requiring a repeat operation. While management of gallstone ileus can be achieved through a single-stage operation including enterolithotomy and cholecystectomy with repair of biliary-enteric fistula or by enterolithotomy alone, the literature supports enterolithotomy alone as the treatment of choice for gallstone ileus due to decreased mortality and morbidity. However, the latter approach does not obviate potential recurrence. We present this case of recurrent gallstone ileus to elucidate and review the pathogenesis, presentation, diagnosis, and consensus recommendations regarding management of this disorder.

  3. Acute Recurrent Pancreatitis

    Full Text Available History, physical examination, simple laboratory and radiological tests, and endoscopic retrograde cholangiopancreatography (ERCP are able to establish the cause of recurrent acute pancreatitis in 70% to 90% of patients. Dysfunction of the biliary and/or pancreatic sphincter, as identified by sphincter of Oddi manometry, accounts for the majority of the remaining cases. The diagnosis may be missed if the pancreatic sphincter is not evaluated. Pancreas divisum is a prevalent congenital abnormality that is usually innocuous but can lead to recurrent attacks of acute pancreatitis or abdominal pain. In select cases, endoscopic sphincterotomy of the minor papilla can provide relief of symptoms and prevent further attacks. A small proportion of patients with idiopathic pancreatitis have tiny stones in the common bile duct (microlithiasis. Crystals can be visualized during microscopic analysis of bile that is aspirated at the time of ERCP. Neoplasia is a rare cause of pancreatitis, and the diagnosis can usually be established by computerized tomography or ERCP. A wide variety of medications can also cause recurrent pancreatitis. ERCP, sphincter of Oddi manometry, and microscopy of aspirated bile should be undertaken in patients with recurrent pancreatitis in whom the diagnosis is not obvious.

    2012-10-01

    We present a case of an elderly non-smoking gentleman who, since 2005, had been admitted multiple times for recurrent episodes of shortness of breath, wheeze, cough and sputum. The patient was treated as exacerbations of chronic obstructive pulmonary disease (COPD) and\\/or lower respiratory tract infections. Bronchoscopy was done which revealed multiple hard nodules in the trachea and bronchi with posterior tracheal wall sparing. Biopsies confirmed this as tracheopathia osteochondroplastica (TO). He had increasing frequency of admission due to methicillin-resistant Staphylococcus aureus and pseudomonas infections, which failed to clear despite intravenous, prolonged oral and nebulised antibiotics. The patient developed increasing respiratory distress and respiratory failure. The patient died peacefully in 2012. This case report highlights the typical pathological and radiological findings of TO and the pitfalls of misdiagnosing patients with recurrent chest infections as COPD.

    The Chronic Inflammatory Demyelinating Polyradiculoneuropathies (CIDP) constitute a syndrome whose incidence is difficult to evaluate, and is probably underestimated. In the course of this presentation, we deliberately restricted discussion to issues raised in recent years concerning the extent of this syndrome. We discuss diagnostic criteria, especially electrophysiological ones. As the criteria proposed by the ad hoc committee of the American Academy of Neurology in 1991 have been questioned due to lack of sensitivity, new ones have been proposed recently. We briefly discuss the different types of chronic dysimmune demyelinating neuropathy: not only the CIDP, but also the Lewis and Sumner syndrome or multifocal inflammatory demyelinating neuropathy and the multiple conduction block neuropathies. At last, we point out the consistent finding of axonal involvement in the course of a chronic demyelinating neuropathy; over time, it can become pre-dominant, which may make diagnosis difficult by suggesting a chronic axonal neuropathy that may be assumed to be primary. Consideration of these points may help clinicians recognize more chronic dysimmune neuropathies, for which immunosuppressive therapy has been found to be effective.

    Full Text Available Context Postoperative endocrine and exocrine insufficiencies following traditional pancreatectomies might cause a deterioration of the quality of life and surgical outcome. Parenchyma-sparing pancreatectomies have been utilized in benign lesions and low-grade malignancies. Case report A 67-year-old female with a past history of right nephrectomy for renal cell carcinoma 20 years earlier was referred to our institute with obstructive jaundice and multiple nodules in the pancreas. Computed tomography demonstrated five well-demarcated, strongly enhanced nodules with diameters of 5.5 cm in the head, 2.0 and 1.8 cm in the body, and 1.2 and 1.0 cm in the tail. Fluorine-18 fluorodeoxyglucose positron emission tomography did not demonstrate any extrapancreatic uptake. A middle-preserving pancreatectomy was performed after ultrasonography had confirmed arterial perfusion in the middle segment. A histological study demonstrated metastatic clear cell renal carcinoma. To date, the patient has remained without recurrence for two and a half years since surgery. A minimal administration of insulin has been necessary; however, C-peptide is detectable and nutritional status is comparatively good. Conclusion A middle-preserving pancreatectomy is a useful procedure in a parenchymasparing pancreatectomy for resecting multifocal lesions in the head, body and tail of the pancreas.

    Prpose: To observe different features of indocyanine green angiography(ICGA) andtifocal electroretinography (ERG) in the diffuse and regional type of Bieti′sc stalline retinopathy (BCR). Thods: ICGA and the multifocal ERG were performed in two cases of the diffuse andregional type of BCR respectively. These data were compared with fluoresceinangiography (FA), standard Ganzfeld ERG, and visual field testing. Results: In the regional case, ICGA revealed reduced perfusion of the choroidalcirculation in the early phase and multiple hypofluorescent spots in the posterior pole in the late phase, due to choriocapillaris filling defect; the extent of choroiocapillaris losswas shown in early phase of ICGA and there were multifocal hyperfluorescent dotssurrounding hypofluorescent spots in late phase in the diffuse case. The multifocal ERGshowed that the central responses were markedly depressed, corresponding to the visualfield defects, while the findings of Ganzfeld ERG were normal in the regional BCR;however, both the multifocal ERG and Ganzfeld ERG were severely subnormal in thediffuse case.Conclusions: The features of ICGA and multifocal ERG are different between the diffuseand regional BCR. In the meantime, the two tools are also useful to differentiate the typeand assess the extentof evolution in BCR.

    Full Text Available PURPOSE: To compare the visual outcome, contrast sensitivity and wavefront analysis of patients that underwent cataract surgery and implantation of AcrySof SN60D3 multifocal intraocular lens with those who received the AcrySof SN60AT monofocal IOL. METHODS: This was a prospective clinical trial of forty eyes that received the multifocal IOL and thirty-two eyes that received the monofocal IOL after phacoemulsification. RESULTS: Values for total and spherical aberrations in the multifocal group were statistically lower than in the monofocal group. In the monofocal group, 75% achieved uncorrected intermediate visual acuities between Jaeger 1 and 6. In the multifocal group, 75% of the eyes achieved more than Jaeger 6. At least 87.5% of the multifocal group and 6.3% of the monofocal group achieved monocular uncorrected near acuity of 20/30 (J2, N5 or better. And 90.0% of the eyes in the multifocal group and 37.5% in the monofocal group achieved an uncorrected near acuity of 20/40 (J3, N6 or better. The mean spherical error was 0.11 D in the multifocal group and -0.18 D in the monofocal group (p=0.0379. The SN60D3 group compared to SN60AT group had low contrast sensitivity (log units with statistically significant differences in 6.0 cpd in photopic conditions (p=0.014 and the SN60D3 group compared to SN60AT group had higher contrast sensitivity (log units under mesopic conditions (p=0.044. CONCLUSION: The multifocal IOLs induced less spherical aberration than monofocal IOLs and predictably good uncorrected distance and uncorrected near acuities. However, contrast sensitivity was lower in the multifocal group.OBJETIVO: Comparar a performance visual, sensibilidade ao contraste e de wavefront com OPD-Scan em pacientes submetidos a cirurgia de facoemulsificação com implante de lente intraocular AcrySof SN60D3 multifocal e AcrySof SA60AT monofocal.

    2011-01-01

    Crohn's disease (CD) is a chronic inflammatory disease of the digestive tract with systemic manifestations. Etiology is unknown, even if immunological, genetic and environmental factors are involved. The majority of CD patients require surgery during their lifetime due to progressive bowel damage, but, even when all macroscopic lesions have been removed by surgery, the disease recurs in most cases. Postoperative management represents therefore a crucial mean for preventing recurrence. Several drugs and approaches have been proposed to achieve this aim. Endoscopic inspection of the ileocolic anastomosis within 1 year from surgery is widely encouraged, given that endoscopic recurrence is one of the greatest predictors for clinical recurrence. A strategy should be planned only after stratifying patients according to their individual risk of recurrence, avoiding unnecessary therapies when possible benefits are reduced, and selecting high-risk patients for more aggressive intervention.

    2006-05-01

    We propose an extension of the recurrence plot concept to perform quantitative analyzes of roughness and disorder of spatial patterns at a fixed time. We introduce spatial recurrence plots (SRPs) as a graphical representation of the pointwise correlation matrix, in terms of a two-dimensional spatial return plot. This technique is applied to the study of complex patterns generated by coupled map lattices, which are characterized by measures of complexity based on SRPs. We show that the complexity measures we propose for SRPs provide a systematic way of investigating the distribution of spatially coherent structures, such as synchronization domains, in lattice profiles. This approach has potential for many more applications, e.g., in surface roughness analyzes.

    The long-term evolution of epidemic processes depends crucially on the structure of contact networks. As empirical evidence indicates that human populations exhibit strong community organization, we investigate here how such mesoscopic configurations affect the likelihood of epidemic recurrence. Through numerical simulations on real social networks and theoretical arguments using spectral methods, we demonstrate that highly contagious diseases that would have otherwise died out rapidly can persist indefinitely for an optimal range of modularity in contact networks.

    2013-10-15

    Purpose: To evaluate renal function changes related to radiofrequency ablation (RFA) for the treatment of multifocal renal neoplasms. Methods: This is an institutional review board-approved, Health Insurance Portability and Accountability Act compliant retrospective study of all patients treated with computed tomography guided RFA for multifocal renal neoplasms at one institution. Fifty-seven subjects, mean age 70 (range 37-88) years, underwent RFA of 169 renal neoplasms (average size 2.0 cm). Subjects had between 2 and 8 (mean 2.96) neoplasms ablated. Estimated glomerular filtration rate (eGFR) was measured before and after RFA. Complications related to RFA were recorded. Results: eGFR decreased on average of 4.4 % per tumor treated and 6.7 % per ablation session (average 1.76 tumors treated per session). For subjects with the largest neoplasm measuring >3 cm, eGFR decreased an average of 14.5 % during the course of their treatment. If the largest neoplasm measured 2-3 cm, eGFR decreased an average of 7.7 %, and if the largest neoplasm measured <2 cm, eGFR decreased an average of 3.8 %. Subjects with reduced baseline renal function were more likely to have a greater decline in eGFR after RFA. There was a minor complication rate of 6.3 % (6 of 96 sessions), none of which required treatment, and a major complication rate of 4.2 % (4 of 96 sessions). Conclusion: RFA for the treatment of multifocal renal neoplasms results in mild decline of renal function.

    We compared the electrodiagnostic studies of 40 patients with chronic acquired demyelinative neuropathy and 18 patients with familial demyelinative neuropathy. Patients with acquired neuropathy had differential slowing of conduction velocity when distal latencies were compared with more proximal conduction velocities in the same nerve, when equivalent segments of different nerves were compared, and when dispersion of compound motor action potentials was examined. Conduction block was noted in some patients. Patients with familial disease had uniform conduction slowly of all nerve segments, and conduction block was not seen. Chronic acquired demyelinative neuropathy is characterized by multifocal slowing of nerve conduction, whereas familial demyelinative neuropathy is characterized by uniform conduction slowing.

    Phase-only modulations derived from the Debye approximation of the Richards–Wolf vectorial integral are used to produce a multifocal spot array. An analytical solution, which controls the position of each focal spot, can generate phase modulation images which are loaded into spatial light modulators. The calculated field distributions and the experimental images of the spot array on the back aperture of the objective are both demonstrated and validated. By overlapping the discrete focal points, continuous nano-structures of arbitrary marks can be achieved conveniently and easily. The above-proposed approach offers opportunities for flexible laser printing and creative micro-manipulation in the future.

    MRI was used to study the effects of introducing cidofovir (HPMPC, Vistide) to the antiretroviral therapy of a 33-year-old white man diagnosed as having progressive multifocal leukoencephalopathy (PML) secondary to AIDS. In response to combined cidofovir and antiretroviral therapy he showed significant clinical improvement. MRI showed a decrease in extent of existing lesions, without new ones. Blood chemistry information obtained indicated some involvement of immunologic mechanisms: the CD4:8 ratio showed improvement from an average of 0.08 before treatment to 0.13 during therapy. (orig.)

    Focal epithelial hyperplasia is a rare contagious disease caused by human papilloma virus. Usually HPV involves either cutaneous or mucosal surfaces, whereas concomitant mucocutaneous involvement is extremely rare. We report such a unique case of multifocal epithelial hyperplasia involving multiple sites of oral cavity along with skin lesions in a 65-year-old female. We also discuss the probable multifactorial etiology and variable clinical presentations of the lesions, including evidence of HPV 16 expression, as detected by polymerase chain reaction. The present report illustrates the need for careful examination and prompt diagnosis of the disease, as it might be associated with high risk genotypes such as HPV 16 and 18. PMID:24455323

    Implantation of multifocal intraocular lenses has become a rutine nowadays, but achieving good visual results requires a perfect intraoperative technique and also an adequate preoperative selection of the patients. We analysed the wave front aberrations (spherical aberations, coma and astigmatism) in the eyes implanted with ReStor + 3 IOL, and we realized some clinical correlations of these aberations with the pupil diameter in scotopic and fotopic conditions, kappa angle, IOL centration, residual refraction errors postoperatively. Taking into account the causes of postoperative high order aberration will allow the surgeon to make a good selection of the patiens and to a higher degree of satisfaction of both sides.

    Levamisole is a common adulterant in cocaine and has previously been associated with a variety of serious complications including multifocal inflammatory leukoencephalopathy (MIL). There have been several reports of MIL in patients taking cocaine and, though suspected, the presence of levamisole was not confirmed. We present a case of a 63-year-old woman presenting with stupor and spastic quadraparesis found to have urine positive for cocaine and levamisole. An MRI brain revealed innumerable FLAIR hyperintensities with restricted diffusion and incomplete ring-enhancement. This is the first case to confirm the presence of levamisole in a patient with MIL associated with cocaine use.

    Progressive multifocal leucoencephalopathy (PML) is an opportunistic, demyelinating neurological disease caused by reactivation of the JC polyomavirus. PML occurs almost exclusively in immunosuppressed individuals, with only isolated case reports of PML occurring in patients without apparent immunosuppression. Idiopathic CD4+ lymohocytopenia (ICL) is a syndrome defined by the Centre for Disease Control and Prevention as a CD4+ count <300 cells\\/uL or <20% of total T cell count on >1 occasion, with no evidence of human immunodeficiency virus (HIV) infection, and the absence of other known immunodeficiency or therapy associated with lymphocytopenia. We describe a case of PML occurring in a patient with idiopathic CD4+ lymphocytopenia.

    A 34-year-old woman presented with urination difficulty and consciousness disturbance, followed by persistent neurologic findings, such as semicomatose mental status and bilateral optic neuritis, and monophasic clinical course. Cranial CT showed multifocal low density areas in cerebral white matter. The patient was clinically diagnosed as having acute disseminated encephalomyelitis. She died of sepsis four months later. Autopsy revealed multifocal large demyelinating lesions confined to the cerebral white matter, shown as low density areas on CT scans, and demyelinating plaques scattered in the optic nerves and chiasm, and cerebral peduncle. The final diagnosis was acute multiple sclerosis. The CT appearance of multifocal low density areas was most likely due to demyelinating lesions causing edema and tissue necrosis. (Namekawa, K.).

    Two adult patients are described with multifocal osteolytic lesions radiologically simulating a vascular tumor. One patient had multiple bones involved. Histologically, the individual lesions had the features of the nidus of osteoid osteoma/osteoblastoma. A review of the English language medical literature yielded only one other reported case with similar features. The process is designated as osteoblastomatosis to indicate its bone-forming character, prominent osteoblast proliferation, and multiplicity. The cases are distinguished from multifocal/multicentric osteoid osteoma and osteoblastoma, and from benign and malignant vascular tumors. (orig.)

    2017-03-01

    In this paper, we propose a new method of multiscale recurrence quantification analysis (MSRQA) to analyze the structure of order recurrence plots. The MSRQA is based on order patterns over a range of time scales. Compared with conventional recurrence quantification analysis (RQA), the MSRQA can show richer and more recognizable information on the local characteristics of diverse systems which successfully describes their recurrence properties. Both synthetic series and stock market indexes exhibit their properties of recurrence at large time scales that quite differ from those at a single time scale. Some systems present more accurate recurrence patterns under large time scales. It demonstrates that the new approach is effective for distinguishing three similar stock market systems and showing some inherent differences.

    Background: This study evaluated the visual function after implantation of a multifocal toric intraocular lenses (IOLs). Materials and Methods: This study involved 10 eyes from eight cataract patients with corneal astigmatism of 1.0 diopter (D) or higher who had received phacoemulsification with implantation of an AcrySof IQ ReSTOR Toric IOL. Six-month evaluations included visual acuity, spherical equivalent (SE), defocus curve, residual astigmatism, IOL rotation, contrast sensitivity (CS), wavefront aberrations, modulation transfer function (MTF), and patient satisfaction assessments. Results: At 6 months postoperatively, uncorrected distance visual acuity (logarithm of the minimum angle of resolution) was 0.09 ± 0.04, corrected distance visual acuity was 0.02 ± 0.11, and uncorrected near visual acuity was 0.12 ± 0.07. The mean SE was −0.095 ± 0.394 D (±0.50 D in 90%). Refractive astigmatism at the 6-month follow-up visit was significantly reduced to 0.35 ± 0.32 D from 1.50 ± 0.41 D presurgery (P 0.05). There was an increase in MTF results between preoperative and postoperative evaluations at all spatial frequencies. Conclusions: The diffractive multifocal toric IOL is able to provide a predictable astigmatic correction with apparently outstanding levels of optical quality after implantation. PMID:27221680

    Cystic neoplasms of the pancreas are relatively rare, comprising 10 percent of pancreatic cysts and only 1 percent of pancreatic cancers. Cystic neoplasms include mucinous cystic neoplasms, serous cystadenomas,papillary cystic tumors, cystic islet cell tumors and intraductal papillary mucinous neoplasms of the pancreas (IPMNs). IPMN was first described in 1982.It has been most commonly described in 60 to 70 years old males, and represents a relatively "new" but increasingly recognized disease. The improvement and widespread use of modern imaging equipments and heightened awareness of physicians contribute to the increasing incidence of IPMN. The majority of IPMNs are located in the pancreatic head (75%) while the rest involves the body/tail regions. Multifocal IPMNs have been hypothesized, but the true presence of multifocality is unknown. Here we present a 72-yearold male diagnosed with IPMN (carcinoma in situ) in the pancreatic head and a branch duct type IPMN (duct atypia) in the pancreatic body and tail. The patient underwent a Whipple intervention and a distal pancreatectomy. A three-year disease-free survival has been observed so far.

    Miller Fisher syndrome (MFS) is a variant of Guillan Barre syndrome characterized by the triad of ophthalmoplegia, ataxia and areflexia. Recurrences are exceptional with Miller Fisher syndrome. We are reporting a case with two episodes of MFS within two years. Initially he presented with partial ophthalmoplegia, ataxia. Second episode was characterized by full-blown presentation characterized by ataxia, areflexia and ophthalmoplegia. CSF analysis was typical during both episodes. Nerve conduction velocity study was fairly within normal limits. MRI of brain was within normal limits. He responded to symptomatic measures initially, then to steroids in the second episode. We are reporting the case due to its rarity.

    Full Text Available Antiphospholipid antibodies (APA are associated with thrombosis, thrombocytopenia and fetal loss but they occur in a variety of diseases. Despite many efforts, a correlation between the specificity of particular subgroups of APA and particular clinical situations remains to be established. The antigens at the origin of APA remain to be identified. We discuss here the possible links between cell apoptosis or necrosis, leading to plasma membrane alterations, and the occurrence of APA in response to sustained stimulation. The pathogenic potential of APA is also considered with respect to recurrent pregnancy loss.

    We examine relationships between two minors of order n of some matrices of n rows and n+r columns. This is done through a class of determinants, here called $n$-determinants, the investigation of which is our objective. We prove that 1-determinants are the upper Hessenberg determinants. In particular, we state several 1-determinants each of which equals a Fibonacci number. We also derive relationships among terms of sequences defined by the same recurrence equation independently of the initial conditions. A result generalizing the formula for the product of two determinants is obtained. Finally, we prove that the Schur functions may be expressed as $n$-determinants.

    Full Text Available Background: Multifocality, multicentricity and extension beyond the prostate capsule are all characteristics of prostatic adenocarcinoma that may escape diagnosis by conventional CT scanning or MRI. This study was designed to assess the diagnostic value of magnetic resonance spectroscopy (MRS in prostatic carcinoma and its compatibility with prostatic specific antigen (PSA as the conventional method.Methods: In this cross-sectional study, we recruited 139 patients with previous radical prostatectomy referring to Radiology department of Hazrate-e-Rasul Hospital during the first half of 2011 for the evaluation of local recurrence. Traditionally, local recurrence is defined as serum PSA concentration >0.2 ng/dl. We used 1.5-tesla Siemens Avanto MRI unit with endorectal coil and measured creatine, choline and citrate levels before calculating choline-creatine/citrate ratio. Correlation between MRS findings with PSA concentration was evaluated in regards to the multiple levels of the previously mentioned ratio.Results: Local recurrence was found in 107 (77% patients based on PSA levels. The mean values for serum PSA levels and creatine-choline/citrate ratio were significantly different in patients with and without local recurrence. Creatine-choline/citrate ratios greater than 50, 100 and 150 (as different cut-off points of recurrence were respectively seen in 104, 102 and 97 patients and agreement ratio between MRS and PSA in these levels were 94.1%, 94.4% and 85.1%, respectively. Correlation coefficient between these two methods was 0.481.Conclusion: MRS is a valuable tool for evaluating recurrence inpatients with prostate cancer treated by radical prostatectomy and it is in good agreement with serum PSA levels.

    2012-01-01

    Background and Objectives: To determine prostate cancer biochemical recurrence rates with respect to surgical margin (SM) status for patients undergoing robotic-assisted laparoscopic radical prostatectomy (RALP). Methods: IRB-approved radical prostatectomy database was queried. Patients were stratified as low, intermediate, and high risk according to D’Amico's risk classification. Postoperative prostate-specific antigen (PSA) values were obtained every 3 mo for the first year, then biannually and annually thereafter. Biochemical recurrence was defined as ≥0.2ng/mL. Patients receiving adjuvant or salvage treatment were included. Positive surgical margin was defined as presence of cancer cells at inked resection margin in the final specimen. Margin presence (negative/positive), margin multiplicity (single/multiple), and margin length (≤3mm focal and >3mm extensive) were noted. Kaplan-Meier curves of biochemical recurrence-free survival (BRFS) as a function of SM were generated. Forward stepwise multivariate Cox regression was performed, with preoperative PSA, Gleason score, pathologic stage, prostate gland weight, and SM as covariates. Results: At our institution, 1437 patients underwent RALP (2003-2009). Of these, 1159 had sufficient data and were included in our analysis. Mean follow-up was 16 mo. Kaplan-Meier curves demonstrated significant increase in BRFS in low-risk and intermediate-risk groups with negative SM. Overall BRFS at 5 y was 72%. Gleason score, pathologic stage, and SM status were significant prognostic factors in multivariate analysis. Conclusions: Negative surgical margins resulted in lower biochemical recurrence rates for low-risk and intermediate-risk groups. Multifocal and longer positive margins were associated with higher biochemical recurrence rates compared with unifocal and shorter positive margins. Documenting biochemical recurrence rates for RALP is important, because this treatment for localized prostate cancer is validated. PMID

  6. Recurrent correlation associative memories.

    Science.gov (United States)

    Chiueh, T D; Goodman, R M

    1991-01-01

    A model for a class of high-capacity associative memories is presented. Since they are based on two-layer recurrent neural networks and their operations depend on the correlation measure, these associative memories are called recurrent correlation associative memories (RCAMs). The RCAMs are shown to be asymptotically stable in both synchronous and asynchronous (sequential) update modes as long as their weighting functions are continuous and monotone nondecreasing. In particular, a high-capacity RCAM named the exponential correlation associative memory (ECAM) is proposed. The asymptotic storage capacity of the ECAM scales exponentially with the length of memory patterns, and it meets the ultimate upper bound for the capacity of associative memories. The asymptotic storage capacity of the ECAM with limited dynamic range in its exponentiation nodes is found to be proportional to that dynamic range. Design and fabrication of a 3-mm CMOS ECAM chip is reported. The prototype chip can store 32 24-bit memory patterns, and its speed is higher than one associative recall operation every 3 mus. An application of the ECAM chip to vector quantization is also described.

    Full Text Available Venous thrombosis, including deep vein thrombosis and pulmonary embolism, is a common disease that frequently recurs. Recurrence can be prevented by anticoagulants, but this comes at the risk of bleeding. Therefore, assessment of the risk of recurrence is important to balance the risks and benefits of anticoagulant treatment. This review briefly outlines what is currently known about the epidemiology of recurrent venous thrombosis, and focuses in more detail on potential new risk factors for venous recurrence. The general implications of these findings in patient management are discussed.

    1990-01-01

    This descriptive study of the perceptions and needs of people with recurrent malignancies asks three questions: How do patients describe the meaning of a recurrence of cancer? Do individuals perceive the diagnosis of recurrence and the initial diagnosis of cancer differently? What are the key psychosocial problems associated with recurrent cancer? The theoretical framework was based on Lazarus and Folkman's theory of stress, appraisal, and coping. Subjects completed the Impact of Event Scale (IES), the Psychosocial Adjustment to Illness Scale--Self-Report (PAIS), and a semistructured qualitative interview. The interview elicited perceptions of the event of recurrence and differences between the diagnosis of recurrence and the initial diagnosis. The convenience sample included 40 patients diagnosed with recurrent cancer within the last 30 days. Many subjects (78%) reported that the recurrence was more upsetting than the initial diagnosis. Scores on both the IES and the PAIS were high when compared to normative samples of patients with cancer suggesting that this sample of patients experienced a lot of psychological distress as well as problems at home, work, and in their social lives. These concerns often were unknown to caregivers. Although more research is needed, the authors propose that, with more accurate assessment, more effective intervention could be implemented and the quality of life improved for patients with recurrent cancer.

    目的 探讨可能影响硬膜下血肿术后复发的相关因素.方法 对236例经钻孔引流手术治疗慢性硬膜下血肿病人的临床资料进行回顾性分析.结果 本组复发率为9.15%.术后复发与引流时间有关(x2=11.519,P<0.01).引流时间对60岁以上病人术后复发率影响显著(x2=11.689,P<0.01),而对60岁以下病人无明显影响.结论 对老年慢性硬膜下血肿病人,钻孔引流术后的引流时间应延长至3d,而对较为年轻的病人则可早期拔除引流.%Objective To investigate the influence of different suhmucosal injections on endoscopic resection of polyps in digestive tract. Methods By employing high frequency clectrotomy, 60 palients with gastrointestinal polyps were equally randomized to two groups as control and observation group. To the patients in control group, the submucosal injections of normal sa-line plus methylene blue at surgery were done; to those in observation group, submucosal injections of glycerine-fructose plus methylenc blue were offered. Small amounts of adrenalin were added to the injections of both groups. The effectiveness between the two groups was compared. Results The operations in both groups were completed in one time. The dosage of the injections, operating time and the cases of duplicate injection in the observation group were less than that in the control group (l - 3. 511,2. 954;X2-=5.454;P<0.05). All the patients were cured and no recurrences were recorded in six months of follow-up. Conclusion Submucosal injection of glycerine-fructose plus methylene blue to be used for endo.scopic polypectomy may obtain a good effectiveness.

    Sobel, Jack D

    2016-01-01

    Recurrent vulvovaginal candidiasis (RVVC) is a common cause of significant morbidity in women in all strata of society affecting millions of women worldwide. Previously, RVVC occurrence was limited by onset of menopause but the widespread use of hormone replacement therapy has extended the at-risk period. Candida albicans remains the dominant species responsible for RVVC, however optimal management of RVVC requires species determination and effective treatment measures are best if species-specific. Considerable progress has been made in understanding risk factors that determine susceptibility to RVVC, particularly genetic factors, as well as new insights into normal vaginal defense immune mechanisms and their aberrations in RVVC. While effective control of RVVC is achievable with the use of fluconazole maintenance suppressive therapy, cure of RVVC remains elusive especially in this era of fluconazole drug resistance. Vaccine development remains a critical challenge and need.

    Progressive multifocal leukoencephalopathy (PML), a fatal demyelinating disease caused by JC virus (JCV) infection of oligodendrocytes, may develop in patients with immune disorders following reactivation of chronic benign infection. Mutations of JCV capsid viral protein 1 (VP1), the capsid protein involved in binding to sialic acid cell receptors, might favor PML onset. Cerebrospinal fluid sequences from 37/40 PML patients contained one of several JCV VP1 amino acid mutations, which were also present in paired plasma but not urine sequences despite the same viral genetic background. VP1-derived virus-like particles (VLPs) carrying these mutations lost hemagglutination ability, showed different ganglioside specificity, and abolished binding to different peripheral cell types compared with wild-type VLPs. However, mutants still bound brain-derived cells, and binding was not affected by sialic acid removal by neuraminidase. JCV VP1 substitutions are acquired intrapatient and might favor JCV brain invasion through abrogation of sialic acid binding with peripheral cells, while maintaining sialic acid–independent binding with brain cells.

    OBJECTIVE To investigate the clinical efficacy for nasal endoscopic surgery in the treatment of the recurrent sinus and nasal polyps. METHODS The clinical effects and complications of 325 cases with recurrent chronic sinusitis and nasal polyps by endoscopic sinus surgery were analyzed retrospectively. The clinical effect for endoscopic sinus surgery in the treatment of recurrent chronic sinusitis and nasal polyps was evaluated comprehensively. RESULTS 325 patients were taken the implementation of endoscopic sinus surgery, which carried out the first sinus surgery in 157 cases. 135 patients were cured after endoscopic nasal surgery, the cure rate was 85.99%. 93 cases were conducted with 2 sinus surgery after endoscopic nasal surgery, 69 cases were cured, and the cure rate was 73.91%. 52 cases were with three sinus surgery, 31 cases were cured, and the cure rate was 59.61%.23 cases were taken the implementation of over 4 sinus surgery, 11 cases were cured, and the cure rate was 47.83%. The cure rate for different patients with sinus surgery was significantly different (P < 0.05). The incidence of complications after endoscopic nasal surgery was increasing with the increase in the number of sinus surgery. CONCLUSION The endoscopic sinus surgery can cure for recurrent patients with chronic sinusitis and nasal polyps effectively. But the cure rate of endoscopic sinus surgery is declining with the increase in the number of relapses sinus surgery. So we should take endoscopic sinus surgery as soon as possible for recurrence in patients to avoid the decrease of treatment efficacy for the repeated incidence.%目的 探讨鼻内镜手术用于复发性鼻窦鼻息肉的临床疗效.方法 回顾性分析325例复发性慢性鼻窦炎鼻患内患者采用鼻内镜手术治疗的临床效果及并发症情况,综合评价鼻内镜手术在复发性慢性鼻窦鼻患肉治疗的临床效果.结果 325例患者均实施鼻内镜手术,其中进行过1次鼻窦手术者157

    Full Text Available Abstract Background To diagnose multiple sclerosis (MS, evidence for dissemination in space and time is required. There is no clear definition on how symptoms and signs of a patient indicate clinical dissemination in space. To provide a uniform approach on this subject, a clinical classification system was described recently differentiating patients with mono- and multifocal clinical presentation. Here we assess the predictive value of clinically defined dissemination in space at first presentation for time to clinically definite MS (CDMS. Methods Four hundred and sixty-eight patients with a first episode suggestive of MS were classified as clinically mono- or multifocal by two neurologists blinded to magnetic resonance imaging (MRI results. These patients were part of the BENEFIT study in which 292 patients were randomized to interferon beta-1b (IFNB-1b and 176 to placebo. By using Kaplan-Meier statistics the risk for CDMS was studied in mono- and multifocal patients of the placebo group, both with and without taking into account MRI measures of potential prognostic relevance. Results Time to CDMS was similar in monofocal and multifocal patients. In monofocal patients, the risk for CDMS over 2 years was significantly higher when ≥ 9 T2 lesions or at least one Gd-enhancing lesion were present at the first event or 3 or 6 months after the first event. In patients with multifocal presentation, these MRI measures had no significant added value in predicting time to CDMS. Conclusion These data indicate that a carefully performed neurological assessment of symptoms and signs, combined with lesions on MRI, is important for defining the risk of conversion to CDMS.

    Objective To examine the relationship between oral positive Helicobacter pylori (Hp) and the gastric recur-rent Hp infection in patients with chronic periodontitis. Methods One hundred and forty periodontitis patients with gastric symptoms were enrol ed in this study. Saliva specimens were col ected for detection of Hp in oral cavity and gastroscopy was undertaken for detection Hp in stomach. For gastric Hp positive patients, 14C- urea breath test was performed 6 months after Hp eradication therapy. Results The rate of oral positive Hp in patients with positive gastric Hp infection was higher than that in patients with negative gastric Hp (P<0.05). The rate of oral positive Hp was correlated with severity of periodontitis (P<0.05). In 94 cases of positive gastric Hp infection, the recurrent rate in patients with positive oral Hp was higher than that with negative o-ral Hp 6 months after eradication therapy (P<0.05).Patients with severe periodontitis had higher recurrent rate of gastric Hp in-fection. Conclusion The presence of Hp in oral cavity might be the cause of recurrent gastric Hp infection, particularly in pa-tients with severe periodontitis.%目的:探讨慢性牙周炎患者口腔幽门螺杆菌(Hp)对胃Hp感染复发率的影响。方法选择140例有腹部不适症状、并经全口牙周检查有不同程度慢性牙周炎的患者进行胃镜检查,每例患者均取口腔唾液标本进行口腔Hp检测。对胃Hp感染患者根治后半年分别复查胃Hp的感染状况,胃Hp检测采用14C呼气试验。结果胃Hp阳性慢性牙周炎患者口腔Hp检出率比胃Hp阴性患者高(P<0.05),并与牙周炎的严重程度有一定的关系,重度牙周炎患者口腔Hp检出率比轻度牙周炎患者高,差异有统计学意义(P<0.05)。94例胃Hp阳性患者经药物治疗后半年进行复查,胃Hp感染复发率口腔Hp阳性者与Hp阴性者的差异有统计学意义(P<0.05)。重度牙周炎患者的胃Hp

    2011-10-01

    Full Text Available Background: Progressive multifocal leukoencephalopathy (PML is a demyelinating central nervous system disease caused by JC virus (JCV reactivation in immunocompromised patients. The disease course of PML is often progressive, fatal and at present, there are few reports on successful treatment outcomes. Case Report: A 45-year-old man with systemic sarcoidosis presented with rapidly progressive dementia and right hemiparesis. The patient was diagnosed with PML as confirmed via brain biopsy and JCV PCR. With a combination treatment of cidofovir and mirtazapine, there was significant improvement of neurological symptoms without measurable functional deficit. Conclusion: This case suggests that dual therapy with cidofovir and mirtazapine might be an effective treatment option in PML patients with sarcoidosis.

    2013-01-01

    Full Text Available Focal epithelial hyperplasia is a rare contagious disease caused by human papilloma virus. Usually HPV involves either cutaneous or mucosal surfaces, whereas concomitant mucocutaneous involvement is extremely rare. We report such a unique case of multifocal epithelial hyperplasia involving multiple sites of oral cavity along with skin lesions in a 65-year-old female. We also discuss the probable multifactorial etiology and variable clinical presentations of the lesions, including evidence of HPV 16 expression, as detected by polymerase chain reaction. The present report illustrates the need for careful examination and prompt diagnosis of the disease, as it might be associated with high risk genotypes such as HPV 16 and 18.

    2014-12-01

    Progressive multifocal leukoencephalopathy (PML) is an opportunistic infection of the human nervous system caused by the JC virus. We report what is, to the best of our knowledge, the second reported case using a combination of mefloquine and mirtazapine in a patient with non-AIDS-related PML with a good clinical outcome. Conversely, the recent trial of mefloquine in 21 patients with AIDS and 3 without AIDS failed to show a reduction of JC viral DNA levels in the cerebral spinal fluid. However, the positive clinical response seen in our patient after the initiation of this combination therapy suggests that further studies in the form of randomized controlled trials for the treatment of non-AIDS-related PML are warranted.

    2012-02-01

    Full Text Available Background: Epithelioid hemangioendothelioma (EHE is a rare vascular tumor with malignant biological behavior. It arises from endothelial cells, usually within soft tissues, and can occur in almost all locations. Case Report: We report a unique case of a 25-year-old man who presented with sudden attacks of severe back pain followed by acute non-traumatic paraplegia. Emergency diagnostics revealed a pathologic fracture of the T7 vertebra with tumor tissue invasion of the spinal canal. Furthermore, multifocal metastases were found. Results: To achieve en bloc resection, interdisciplinary surgical approaches were indicated. Despite multimodal therapy concepts, including radiotherapy and chemotherapy as well as endovascular embolization, the patient died within 8 weeks. Conclusion: Prognosis of EHE is unpredictable and mainly determined by its location. The lesions are potentially aggressive; therefore, en bloc resection should be attempted whenever possible. However, as shown in the literature, only 15% of patients are suitable for total resection.

    Multifocal epithelial hyperplasia (MEH) presents as painless, single or multiple nodular or papular lesions with a sessile base, ranging in diameter from 0.1 cm to 1.0 cm, frequently coalescing. Lesion color varies from red to white, depending on the extent of keratinization. The condition appears mainly in children and adolescents and regresses spontaneously. The etiological factors and pathogenesis of MEH are speculative. A 13-year-old boy presented to the Royal Dental Hospital of Melbourne for dental examination revealing several asymptomatic, exophytic, pink, sessile, smooth-surfaced nodules on the lateral borders of the tongue and lingual surface of the lower lip. The subject is of Somalian background and one of 11 siblings aged 2 to 22 years old living with his parents in an overcrowded residence. Examination of other family members revealed the presence of similar lesions in 2 younger sisters. An incisional biopsy confirmed the diagnosis of MEH histopathologically.

    2014-11-01

    Both progressive multifocal leukoencephalopathy (PML) and posterior reversible encephalopathy syndrome (PRES) have been reported as complications of rituximab therapy. These disorders may appear indistinguishable on magnetic resonance imaging (MRI). We report on a 42 year old woman with neuromyelitis optica (NMO) of 10 years duration who developed extensive white matter disease affecting chiefly both parietal lobes 6 months after her first and only dose of rituximab. The MRI findings suggested the diagnosis of PML, but her history was more consistent with PRES. Ultimately, a brain biopsy was performed which was consistent with the diagnosis of PRES. PRES and PML may have overlapping symptomatology and be indistinguishable on MRI. An approach to distinguishing between these two disorders is addressed.

  12. Improvement of the classification accuracy in discriminating diabetic retinopathy by multifocal electroretinogram analysis

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    The multifocal electroretinogram (mfERG) is a newly developed electrophysiological technique. In this paper, a classification method is proposed for early diagnosis of the diabetic retinopathy using mfERG data. MfERG records were obtained from eyes of healthy individuals and patients with diabetes at different stages. For each mfERG record, 103 local responses were extracted. Amplitude value of each point on all the mfERG local responses was looked as one potential feature to classify the experimental subjects. Feature subsets were selected from the feature space by comparing the inter-intra distance. Based on the selected feature subset, Fisher's linear classifiers were trained. And the final classification decision of the record was made by voting all the classifiers' outputs. Applying the method to classify all experimental subjects, very low error rates were achieved. Some crucial properties of the diabetic retinopathy classification method are also discussed.

  13. Media richness and social information processing: rationale for multifocal continuing medical education activities.

    Gilman, S C; Turner, J W

    2001-01-01

    Academic business communication has studied the results of media selection in organizations. Little of this work has been discussed in the context of continuing medical education (CME); however, it may apply to improving the design of educational activities. This article reviews literature on media richness and social information processing theories. The concept of media richness suggests that media choice results from a match between the objective characteristics of the medium and the content requirements of a message. In this context, media include face-to-face conversation and print and electronic media. Social information processing theory suggests that media selection is also based on participants' social norms for how information is communicated in their environment and the participants' familiarity with specific media types. Appraisal of CME with respect to these theories suggests that the complex relationship of CME content and CME participant environments invites the most effective strategies of multiple media experienced over time in what might be called multifocal continuing medical education.

  14. A Novel Segment Classification for Multifocal and Multicentric Breast Cancer to Facilitate Breast-Conservation Treatment.

    Tan, Mona P

    2015-01-01

    Breast conservation treatment (BCT) is an appropriate alternative to mastectomy for the treatment of unifocal breast cancer. Multifocal and multicentric breast cancers (MFMCBC) challenge conventional indications for BCT and are often treated with mastectomy. Following progress in treatment strategies for unifocal tumors, there was a movement to evaluate the use of BCT for MFMCBC. Now a growing body of evidence from retrospective data has emerged, demonstrating acceptable local control and overall survival rates with BCT for MFMCBC. Prospective studies are needed to confirm these findings. One of the possible barriers to such trials is the absence of a standardized classification and nomenclature for MFMCBC at this point in time. A novel segment classification is presented in this article in an endeavor to overcome this deficiency and allow future work on this issue.

    2016-08-15

    Multifocal micronodular pneumocyte hyperplasia (MMPH) is a relatively rare pulmonary disorder that can be associated with tuberous sclerosis complex (TSC). It has been rarely reported in children or adolescents. MMPH is a hamartomatous process of the lung with multiple small nodules, composed of type II pneumocytes. Plain radiography and chest CT in MMPH may demonstrate numerous small nodules measuring 1-10 mm in diameters, distributed randomly throughout both lungs. If MMPH is an initial presentation of TSC, and unless we are familiar with this lung manifestation of TSC, radiologic findings can mimic miliary tuberculosis or metastatic disease. We report a teenage girl with TSC and histologically confirmed MMPH which mimicked miliary tuberculosis at the initial presentation.

    Saito, H; Sakai, H; Fujihara, K; Fujihara, K; Itoyama, Y

    1998-11-01

    We reported a case of acquired immunodeficiency syndrome (AIDS) via multiple blood transfusions, who manifested progressive multifocal leukoencephalopathy (PML) about 18 months after the development of AIDS. PML initiated with right hemiparesis, dysphasia, and Gerstmann's syndrome and resulted in death within 2 months after the onset. Neuroimaging examinations revealed white matter lesions mainly in the left posterior parietal lobe. The cortical gray matter also showed abnormal signal intensity. Peripheral CD4+ lymphocyte count was 81/microl. Routine cerebrospinal fluid (CSF) examinations were negative. CSF antibodies against herpes simplex virus, varicella-zoster virus, cytomegalovirus, Epstein-Barr virus as well as serum antibody against toxoplasma gondii were negative. Though autopsy or biopsy of the brain was not performed, JC virus genomes were detected in the CSF sample by a polymerase chain reaction, and their sequencing showed unique alterations of the regulatory regions, characteristic to PML-type JC virus.

    2017-01-01

    Abstract Persistence of postoperative radicular pain after surgery for multifocal disc herniation (MFDH) is a clinical problem. This study aims to evaluate the effects of a combined treatment approach compared with unilateral stabilization on early postoperative radicular pain in patients with MFDH. Age, sex, level of operation, clinical findings, and radicular pain visual analogue scale (VAS) scores before surgery in the early postoperative period and at 3 months after surgery were retrospectively reviewed for 20 cases of multifocal lumbar disc herniation. The combined approach (translaminar and far lateral) was used for 13 cases. Seven cases underwent transforaminal lumbar interbody fusion (TLIF) and unilateral transpedicular stabilization following total facetectomy. The mean age of the sample was 49.4 ± 10.1 years and the female-to-male ratio was 8:12. The mean VAS scores for radicular pain in cases treated with the combined approach were 8.2, 4.07, and 2.3 in the preoperative and early postoperative periods and 3 months after surgery, respectively. The mean score for radicular pain improved by 50.4% in the early postoperative period and by 72% in the late postoperative period. The mean VAS scores for radicular pain in cases who underwent TLIF and unilateral stabilization after facetectomy were 8.4, 2.1, and 1.4 in the preoperative and early postoperative periods and 3 months after surgery, respectively. The mean VAS score for radicular pain improved by 75% in the early postoperative period and by 83.3% in the late postoperative period. The combined approach is an effective alternative in cases with MFDH. TLIF and unilateral segmental stabilization provide substantial decompression and eliminate mechanical compression by conserving the height of the intervertebral foramen in the event that sufficient decompression is unable to obtain. We suggest that elimination of chemical mediators, particularly those causing pain in the dorsal ganglion, contributes to

    Full Text Available Purpose: To assess the postoperative outcomes of a novel toric multifocal in traocular lens (IOL in patients with cataract and corneal astigmatism. Methods: This prospective nonrandomized study included patients with cataract, corneal astigmatism, and a motivation for spectacle independence. In all patients, a Rayner M-flex® T toric IOL was implanted in the capsular bag. Three months after surgery, the distance, intermediate, and near visual acuities; spherical equivalent; residual refractive astigmatism; defocus curve; and contrast sensitivity were evaluated. A patient satisfaction and visual phenomena questionnaire was administered to all patients. Results: Thirty-four eyes of 18 patients were included in this study. Three months after surgery, the mean corrected distance visual acuity (logMAR was 0.00 ± 0.08 at 6 m, 0.20 ± 0.09 at 70 cm, and 0.08 ± 0.11 at 40 cm. Uncorrected distance vision acuity was 20/40 or better in 100% eyes. The preoperative mean refractive cylinder (RC was -2.19 (SD: ± 0.53. After a 3-month follow-up, the average RC was -0.44 D (SD: ± 0.27; p<0.001. Contrast sensitivity levels were high. At the last follow-up, 87.5% patients were spectacle-independent for near, intermediate, and distance vision, and approximately 44% patients reported halos and glare. Conclusion: Toric multifocal IOL implantation in patients with cataract and corneal astigmatism using the Rayner M-flex® T toric IOL was a simple, safe, and accurate option. This technology provides surgeons with a feasible option for meeting patient expectations of an enhanced lifestyle resulting from decreased spectacle dependence.

    Some patients fulfilling the criteria for the diagnosis of multifocal motor neuropathy with conduction block (MMN-CB) at the onset of disease may subsequently develop a sensory loss associated with electrophysiological sensory abnormalities. The latter could represent an overlap between MMN-CB and multifocal acquired demyelinating sensory and motor (MADSAM) neuropathy. The objective was to specify the features of MMN-CB with sensory loss (MMN-CB-Se). Five patients in a series of 11 consecutive patients who fulfilled the criteria of the American Association of Neuromuscular and Electrodiagnostic Medicine for MMN-CB at the first examination and were treated periodically with intravenous immunoglobulin (IVIg) developed sensory loss in the course of the disease. In these five patients we compared the clinical, laboratory, and electrophysiological features found after the development of sensory loss with those at the first examination. The mean time to appearance of objective sensory signs was 7.2 years. In three of the five patients the sensory loss was preceded by intermittent paresthesias in the same nerve territories as the motor involvement. The most frequent electrophysiological abnormality was amplitude reduction of sensory nerve action potentials. There were no bilateral or symmetrical clinical and electrophysiological sensory abnormalities. Anti-GM1 IgM antibodies were positive in four patients. MMN-CB-Se could be an overlap between MMN-CB and MADSAM. It shares the distribution of the sensory disorders encountered in MADSAM, but it is closer to MMN-CB on clinical and therapeutic levels. Study of more patients would be useful to classify this subgroup more accurately.

Diagnosis of recurrent cases may be challenging. In this study long-term follow-up of recurrent and/or bilateral ON patients is reported in an effort to guide differential diagnosis and treatment.Methods: The study included 474 optic neuropathy patients. Of these, 70 patients with recurrent unilateral or bilateral, and nonrecurrent bilateral ON were assessed. The characteristics of each ON attack, laboratory and magnetic resonance imaging (MRI findings, associated diseases and response to treatment were noted for each patient. Most of the patients were reevaluated in the outpatient clinic. Seven patients were investigated for neuromyelitis optica (NMO-immunoglobulin G (IgG seropositivity.Results: Forty-seven patients had recurrent unilateral ON and 23 had bilateral ON. Mean follow-up was 7.55 years. Final diagnoses for recurrent unilateral group were multiple sclerosis (MS (n = 29, chronic relapsing inflammatory optic neuritis (CRION (n = 11, NMO (n = 4, or autoimmune thyroid disease (n = 3; and for bilateral ON group, MS (n = 4, vasculitis (n = 13, postinfectious ON (n = 4, and sarcoidosis (n = 2. Three patients were positive for NMO antibodies.Conclusion: Based on the data collected, we conclude when recurrent ON causes moderate to severe visual loss in the absence of cranial MRI findings typical of MS, other diagnoses should be considered, including NMO.Keywords: optic neuritis, recurrent, bilateral, multiple sclerosis, neuromyelitis optica

    Primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC) represent major indications for liver transplantation (LT). Despite the steady increase in the incidence and prevalence of PBC, the number of liver transplants for PBC has fallen in recent years, whereas the number of transplants for PSC has remained stable. Indications for LT for PBC and PSC are no different from those of other causes of chronic liver disease, apart from some disease-specific indications. PBC and PSC have more favourable outcomes after LT, compared to viral hepatitis and alcohol-associated liver disease. Numerous studies have clearly demonstrated that PBC and PSC recur after LT. The diagnosis of recurrent disease should be made on agreed criteria. The impact of recurrent disease on survival is unclear. Study of recurrent PBC and PSC may provide a better understanding of the mechanisms of these diseases in the native liver.

    Primary sclerosing cholangitis (PSC) is a chronic progressive inflammatory disease affecting the bile ducts, leading to fibrosis and eventually cirrhosis in most patients. Its etiology is unknown and so far no effective medical therapy is available. Liver transplantation (LTX) is the only curative treatment and at present PSC is the main indication for LTX in the Scandinavian countries. Close to half of the PSC patients experience one or more episodes of acute cellular rejection (ACR) following transplantation and approximately 1/5 of the transplanted patients develop recurrent disease in the graft. In addition, some reports indicate that ACR early after LTX for PSC can influence the risk for recurrent disease. For these important post-transplantation entities affecting PSC patients, we have reviewed the current literature on epidemiology, pathogenesis, treatment and the possible influence of rejection on the risk of recurrent disease in the allograft.

    Background Recurrence of takotsubo cardiomyopathy (TTC) is a well-known complication. However, current literature lists only a few isolated cases. We aimed to determine the incidence and clinical significance of recurrent TTC. Methods & Results Our institutional database constituted a collective of 114 patients diagnosed with TTC since 2003. Close follow-up of these patients revealed a recurrence of TTC in seven of these (6.1%). The time interval between the index event and its recurrence varied between six months and six years. Arterial hypertension was more revealed in the recurrence group of TTC compared to non-recurrence group, (P = 0.02). Chronic obstructive pulmonary disease and/or asthma was more diagnosed in the recurrence group, (P = 0.04). Clinical events like right ventricular involvement, TTC related complications such as life-threatening arrhythmias, pulmonary congestion and in hospital death were observed more frequently in the recurrent episode. Over a mean follow-up of one year the mortality rate was similar in both groups. Conclusions Recurrence of TTC within six years after index event is not an uncommon phenomenon. In the event of right ventricular involvement in the relapse phase, it might be associated with a higher complication rate. TTC recurrence should be the first differential diagnosis in patients with a past history of TTC. PMID:28133464

    The clinical diagnosis of classic Crohn's disease (CD)of the small bowel is based on a typical history, tender right lower quadrant fullness or mass, and characteristic radiographic findings of the terminal ileum. Appendicitis may as well present with chronic or recurrent symptoms and this presentation may be confused with CD. We herein describe the case of a young teenage girl with a presumptive diagnosis of CD, who was ultimately diagnosed as having chronic nongranulomatous appendicitis. The literature on the subject is reviewed.

  7. Recurrent neural collective classification.

    Monner, Derek D; Reggia, James A

    2013-12-01

    With the recent surge in availability of data sets containing not only individual attributes but also relationships, classification techniques that take advantage of predictive relationship information have gained in popularity. The most popular existing collective classification techniques have a number of limitations-some of them generate arbitrary and potentially lossy summaries of the relationship data, whereas others ignore directionality and strength of relationships. Popular existing techniques make use of only direct neighbor relationships when classifying a given entity, ignoring potentially useful information contained in expanded neighborhoods of radius greater than one. We present a new technique that we call recurrent neural collective classification (RNCC), which avoids arbitrary summarization, uses information about relationship directionality and strength, and through recursive encoding, learns to leverage larger relational neighborhoods around each entity. Experiments with synthetic data sets show that RNCC can make effective use of relationship data for both direct and expanded neighborhoods. Further experiments demonstrate that our technique outperforms previously published results of several collective classification methods on a number of real-world data sets.

    Vulvovaginitis is the most common gynecologic condition seen by practitioners rendering primary care to women. Vulvovaginitis Candidiasis (VVC) is the most common type of vaginitis and this study aimed at specifying VVC recurrence during pregnancy. In this prospective study, 150 pregnant women suffering from vaginal excretion, morsus and itching were studied. Initially, the patients were treated using clotrimazole local cream (5 g) for 7 successive days. After initial treatment, the patients were freely visited once a month until delivery considering vaginitis symptoms and VVC recurrence was examined during pregnancy. Mean age of the understudy mothers was 27.26 +/- 3.76. Mean of recurrence number was 0.17 +/- 0.48 during the first trimester. Mean of recurrence number was 0.92 +/- 0.76 during the second trimester. Mean of recurrence number was 2.16 +/- 0.63 during the third trimester. Statistically significant difference was between recurrences during three trimesters of pregnancy (p < 0.001). There is statistically significant difference between mean number of recurrences during three trimesters of pregnancy.

    The reported positions of 964 suspected nova eruptions in M31 recorded through the end of calendar year 2013 have been compared in order to identify recurrent nova candidates. To pass the initial screen and qualify as a recurrent nova candidate two or more eruptions were required to be coincident within 0.1', although this criterion was relaxed to 0.15' for novae discovered on early photographic patrols. A total of 118 eruptions from 51 potential recurrent nova systems satisfied the screening criterion. To determine what fraction of these novae are indeed recurrent the original plates and published images of the relevant eruptions have been carefully compared. This procedure has resulted in the elimination of 27 of the 51 progenitor candidates (61 eruptions) from further consideration as recurrent novae, with another 8 systems (17 eruptions) deemed unlikely to be recurrent. Of the remaining 16 systems, 12 candidates (32 eruptions) were judged to be recurrent novae, with an additional 4 systems (8 eruptions) b...

    2010-09-01

    Full Text Available Recent results about spike-timing-dependent plasticity (STDP in recurrently connected neurons are reviewed, with a focus on the relationship between the weight dynamics and the emergence of network structure. In particular, the evolution of synaptic weights in the two cases of incoming connections for a single neuron and recurrent connections are compared and contrasted. A theoretical framework is used that is based upon Poisson neurons with a temporally inhomogeneous firing rate and the asymptotic distribution of weights generated by the learning dynamics. Different network configurations examined in recent studies are discussed and an overview of the current understanding of STDP in recurrently connected neuronal networks is presented.

    Ohashi described for the first time the IPMN on 1982 as a pancreatic neoplasia with mucine cells forming papillae and producing dilatation of the main pancreatic duct or its branches. The IPMN represent the 1% of the pancreatic tumors and 5% of the cystic neoplasias. It is potentially malignant in a period of five years being more frequent in males between 60-70 and clinically these patients' presents as acute, recurrent or chronic pancreatitis, with an incidence of malignancy from 25% to 70%. CT scan and cholangio MRI allows the diagnosis, the variety, localization and possibility of determine malignancy. The treatment is the Whipple resection. We are reporting the case of an obese middle age male, being observed along the last 10 years because of recurrent pancreatitis with a cystic lesion of the head of the pancreas. The CT scan, endoscopic-ultrasound and the analysis of the liquid content suggested a mucinous lesion, reason why the patient underwent a pancreatic-duodenal resection. The histology study confirms the diagnosis of IPMN.

  13. Dose selection for radioiodine therapy of borderline hyperthyroid patients with multifocal and disseminated autonomy on the basis of {sup 99m}Tc-pertechnetate thyroid uptake

    The aim of this study was to optimise radioiodine therapy of diffuse and nodular toxic goitre by calculation of the radiation dose delivered to the thyroid on the basis of the pretreatment technetium-99m pertechnetate thyroid uptake under thyrotropin suppression (TcTU{sub s}). The TcTU{sub s} value serves as a substitute for the non-suppressible iodine turnover and the functional autonomous mass. Marinelli's formula was used to calculate tissue absorbed doses of 150 Gy, 200 Gy, 250 Gy and 300 Gy to the thyroids of 438 patients with multifocal and disseminated autonomy. The mean age of patients was 70{+-}9 years, and the mean thyroid volume was 54{+-}26 ml. Two hundred and sixty-one of the patients had at least one documented previous episode of overt hyperthyroidism. Tissue absorbed doses were adapted to the pretreatment TcTU{sub s}: 150 Gy for a TcTU{sub s} of 1.5%-2.49%, 200 Gy for a TcTU{sub s} of 2.5%-3.49%, 250 Gy for a TcTU{sub s} of 3.5%-4.49% and 300 Gy for a TcTU{sub s} of {>=}4.5%. Normalisation of TcTU{sub s} and thyrotropin (TSH), thyroid volume reduction and frequency of hypothyroidism and recurrent hyperthyroidism were evaluated 1 year after a single radioiodine therapy. The presented dose strategy resulted in normalisation of TcTU{sub s} in 96% and an increase in TSH to the normal range in 92%. Recurrent hyperthyroidism was observed in only five patients. Thyroid volume decreased from 54{+-}26 before treatment to 34{+-}20 ml, a mean reduction of 37%. The frequency of hypothyroidism, at 0.9%, was encouragingly low. Dose selection in accordance with pretreatment TcTU{sub s} can be recommended for elimination of functional autonomous tissue with a single radioiodine therapy in patients of advanced age with enlarged thyroid glands and relevant autonomous masses who are at risk of developing iodine-induced hyperthyroidism.

    There are few effective treatments for recurrent glioblastoma multiforme (GBM). We present a patient with recurrent GBM who achieved a prolonged response to treatment with afatinib, an irreversible ErbB family blocker, plus temozolomide. A 58-year-old female patient was diagnosed with multifocal primary GBM. After surgical resection, first-line therapy comprised radiotherapy and temozolomide. Following disease progression after 3 temozolomide cycles, the patient entered a phase I/II clinical trial of afatinib (20-40 mg daily for 28 days) plus temozolomide (50 mg/m2 every 21/28 days). Next-generation sequencing analysis of the brain tumor specimen was performed. At the last assessment, 63 treatment cycles had been completed and the patient had survived for ~5 years since recurrence. Significant disease regression was observed after 5 cycles and was maintained during long-term follow-up. Adverse events were consistent with the known tolerability profile of afatinib and were managed by treatment interruption/dose reduction. The patient had several epidermal growth factor receptor (EGFR) aberrations, including gene amplification and EGFRvIII positivity. Three somatic mutations were identified, including an unprecedented extracellular-domain substitution (D247Y). The patient has survived ~6-fold longer than normally expected in patients with recurrent GBM. The complex EGFR genotype may underlie sustained response to afatinib plus temozolomide.

    Ciguatera fish poisoning (ciguatera) is a common clinical syndrome in areas where there is dependence on tropical reef fish for food. A subset of patients develops recurrent and, in some instances, chronic symptoms, which may result in substantial disability. To identify possible biomarkers for recurrent/chronic disease, and to explore correlations with immune gene expression, peripheral blood leukocyte gene expression in 10 ciguatera patients (7 recurrent, 3 acute) from the U.S. Virgin Islands, and 5 unexposed Florida controls were evaluated. Significant differences in gene expression were noted when comparing ciguatera patients and controls; however, it was not possible to differentiate between patients with acute and recurrent disease, possibly due to the small sample sizes involved.

    To study distribution and patterns of nerve hypertrophy in chronic inflammatory demyelinating polyneuropathy (CIDP), magnetic resonance neurography with 3-dimensional reconstruction of short tau inversion recovery images was performed in 33 patients. This technique clearly showed longitudinal morphological changes from the cervical roots to the nerve trunks in the proximal arm. Nerve enlargement was detected in 88% of the patients. According to the clinical subtype of CIDP, typical CIDP patients showed symmetric and root-dominant hypertrophy, whereas Lewis-Sumner syndrome patients had multifocal fusiform hypertrophy in the nerve trunks. The patterns of nerve hypertrophy presumably reflect the different pathophysiology of each CIDP subtype.

    This paper is a first step in the study of the recurrence behavior in random dynamical systems and randomly perturbed dynamical systems. In particular we define a concept of quenched and annealed return times for systems generated by the composition of random maps. We moreover prove that for super-polynomially mixing systems, the random recurrence rate is equal to the local dimension of the stationary measure.

    The Chronic Inflammatory Demyelinating Polyradiculoneuropathies (CIDP) constitute a syndrome whose incidence is difficult to evaluate, and is probably underestimated. In the course of this presentation, we deliberately restricted discussion to issues raised in recent years concerning the extent of this syndrome. We discuss diagnostic criteria, especially electrophysiological ones. As the criteria proposed by the ad hoc committee of the American Academy of Neurology in 1991 have been questioned due to lack of sensitivity, new ones have been proposed recently. We briefly discuss the different types of chronic dysimmune demyelinating neuropathy: not only the CIDP, but also the Lewis and Sumner syndrome or multifocal inflammatory demyelinating neuropathy and the multiple conduction block neuropathies. At last, we point out the consistent finding of axonal involvement in the course of a chronic demyelinating neuropathy; over time, it can become predominant, which may make diagnosis difficult by suggesting a chronic axonal neuropathy that may be assumed to be primary. Consideration of these points may help clinicians recognize more chronic dysimmune neuropathies, for which immunosuppressive therapy has been found to be effective.

    Neurofibromatosis type 1 (NF1) is a clinically and genetically distinct disease involving both neuroectodermal and mesenchymal derivatives. Orofacial manifestations in NF1 have been documented before but occurrence of multifocal intraosseous (IO) and extraosseous (EO) neurofibromas is rare. The present case highlights the importance of imaging findings in the diagnosis and management of multifocal jaw, infratemporal, and parotid neurofibromas with muscular hypoplasia in an eight-year-old girl with NF1. Apart from orthopantomograms (OPG), three-dimensional computed tomography (3D CT) and cross-sectional reformations were valuable in delineating the extent of the lytic lesion and identifying additional bony deformities of the mandible. Magnetic resonance imaging (MRI) helped to identify the solid nature of the lesion and true extent of the soft tissue mass.

    1993-01-01

    Sixteen out of 720 patients with carpal tunnel syndrome who had undergone surgery since 1979 were reoperated for a "recurrence" (2.2%). Twelve of these patients had been originally operated on in our department. Thus, our own recurrence rate is 1.7%. Three patients deteriorated following surgery, 6 had an unsatisfactory improvement, and in 7 the symptoms recurred after initial improvement. Eight of the reoperated patients had a predisposing disease (terminal renal insufficiency, insulin-dependent diabetes mellitus, acromegaly). In 10 of the 16 cases the initial operation had been carried out by surgeons in the first three years of training. Reoperation revealed incomplete splitting of the transverse carpal ligament in 10 cases, compression of the median nerve by the scar in 4, injury of the muscular branch in 1, and an anatomical variant as cause of incomplete decompression in 1 patient. "Recurrences" after carpal tunnel surgery are predominantly due to inadequacies of the first procedure. A remarkable number of patients (50%) has predisposing diseases. Interfascicular or epineural neurolysis and complete exposure and neurolysis of the median nerve and its branches is necessary only in cases of recurrence. Their omission at the first surgery does not result in an increased recurrence rate. Our observations indicate that the number of operations for recurrent carpal tunnel syndrome can probably be reduced when the first operation is performed with care and experience. Patients with carpal tunnel syndrome secondary to a systemic disease are particularly at risk.

  4. Diagnosis and treatment of chronic acquired demyelinating polyneuropathies.

    2014-08-01

    Chronic neuropathies are operationally classified as primarily demyelinating or axonal, on the basis of electrodiagnostic or pathological criteria. Demyelinating neuropathies are further classified as hereditary or acquired-this distinction is important, because the acquired neuropathies are immune-mediated and, thus, amenable to treatment. The acquired chronic demyelinating neuropathies include chronic inflammatory demyelinating polyneuropathy (CIDP), neuropathy associated with monoclonal IgM antibodies to myelin-associated glycoprotein (MAG; anti-MAG neuropathy), multifocal motor neuropathy (MMN), and POEMS syndrome. They have characteristic--though overlapping--clinical presentations, are mediated by distinct immune mechanisms, and respond to different therapies. CIDP is the default diagnosis if the neuropathy is demyelinating and no other cause is found. Anti-MAG neuropathy is diagnosed on the basis of the presence of anti-MAG antibodies, MMN is characterized by multifocal weakness and motor conduction blocks, and POEMS syndrome is associated with IgG or IgA λ-type monoclonal gammopathy and osteosclerotic myeloma. The correct diagnosis, however, can be difficult to make in patients with atypical or overlapping presentations, or nondefinitive laboratory studies. First-line treatments include intravenous immunoglobulin (IVIg), corticosteroids or plasmapheresis for CIDP; IVIg for MMN; rituximab for anti-MAG neuropathy; and irradiation or chemotherapy for POEMS syndrome. A correct diagnosis is required for choosing the appropriate treatment, with the aim of preventing progressive neuropathy.

    Drug induced lupus erythematosus (DIL or DILE) is an autoimmune disorder caused by chronic use of certain drugs. We report a unique case of hydralazine induced lupus syndrome (HILS) with a negative antinuclear antibody in a female patient who was on hydralazine for a period of 1.5–2 years and developed recurrent pericardial effusion as a result of it. Initially her condition was managed with a pericardial window. The recurrence of a massive pericardial effusion necessitated a right hemiperica...

    Full Text Available Background. Main issues of treatment of patients with cicatricial stenosis of trachea (CST are to increase its efficacy and safety, as well as to determine indications and contraindications for circular resection and reconstructive interventions on the trachea in patients with extended lesions of trachea, with stenoses involving subvocal cords part of larynx and well as multifocal narrowing of the trachea which could improve treatment results and quality of life of patients, to gain recovery and reduce disability and mortality.Material and methods. One hundred two patients aged from 11 to 62 years with CST were surgically treated. Stenotic site length in patients varied from 0,3 to 7 cm. Most frequently (64,2%, CST length of more than 2 cm was observed. In critical and decompensated stenosis with diameter of CST up to 5 mm with the threat of asphyxiation by the first stage we used endoscopic laser-and electric destruction of constriction followed by restricted zone bouging. If long-term rehabilitation was necessary and in case of absence of the conditions to the implementation of circular tracheal resection, we used tracheal stents. Circular resection of the trachea was performed in 24 patients. In case of contraindications, 28 patients underwent reconstructive plastic surgery with dissection the stenosis, excision of scar tissue and formation of trachea lumen in T-tube. After removing T-tube plasty of anterior tracheal wall and of soft tissues of the neck defects was performed using local tissues and grafts with microsurgical techniques.Results. Long-term results of treatment evaluated and studied in a period of 6 months to 5 years in 89 (87.3% patients. 13 patients continues to one of the stages of complex treatment. Еhe patients are under dynamic endoscopic control. Good results were achieved in the treatment of 71 patients (79.8%, satisfactory - in 12 (13.4%, unsatisfactory results in 6 (6.7% patients.Conclusions. 1. Patients with CST

    Objective The aims of this study were to identify clinical, intraoperative and pathological prognostic factors for predicting extraurothelial recurrence and cancer-specific survival (CSS) in patients with upper urinary tract urothelial carcinoma (UTUC) who had undergone laparoscopic radical nephroureterectomy (LRNU), and to investigate the site-specific patterns of recurrence and the associated outcomes. Materials and methods A retrospective revision was undertaken of 117 consecutive patients who had undergone transperitoneal LRNU for UTUC between 2007 and 2012. Univariate and multivariate Cox regression analyses were used to identify prognostic factors and Kaplan-Meier was used to estimate CSS. Results With a median follow-up of 20 months, 36 patients (30%) developed extraurothelial recurrence (local and/or distant). In the multivariate analysis, entering the urinary tract during LRNU was related to local recurrence (p = 0.04), management of the distal ureter to CSS (p = 0.003), pathological stage and positive margins to local (p = 0.001, p = 0.013), distant (p = 0.028, p = 0.009) and global recurrence (p = 0.05, p = 0.012) and CSS (p = 0.011, p = 0.042), and multifocality to distant recurrence (p = 0.024). Median time to recurrence was 11.4 months after LRNU. Of 36 patients with progression, 23 (64%) had simultaneous local and distant recurrence and eight had atypical metastases: two port-site metastases, five peritoneal, two subcutaneous and two abdominal wall implants. The 5 year CSS was 61% for all patients with UTUC and 9% for those with recurrence. Conclusions Intraoperative events could have a negative impact on the oncological outcomes of patients with UTUC treated with LRNU. The use of laparoscopy for advanced UTUC may be related to atypical ways of spreading.

    This single group cohort study, undertaken at Aga Khan University Hospital, Karachi, from Jan 2012 to September 2013, assessed patients' satisfaction, spectacle independence and visual disturbance after implantation of multifocal IOLs. A total of 39 patients who underwent bilateral cataract surgery with multifocal IOL implantation were included for telephonic interviews. The mean age of participants was 55.5 ± 8.1 years. The mean follow up time was 9.60 ± 3.19 months. The overall satisfaction rate after surgery was found to be 84.6% and there was no statistically significant association of satisfaction with gender, age or education. In all 84.6%, 94.9% and 84.6% people had spectacle independence for far, intermediate and near, respectively. More than half of participants (59%) had some degree of visual disturbance. In this study, multifocal IOL implantation provided high levels of satisfaction and spectacle independence despite notable risk of halo or glare symptoms at night. Therefore, careful patient selection and preoperative counselling regarding possible risks and benefits is recommended.

    Chronic lymphocytic thyroiditis characterized by multifocal follicular lymphoid cell infiltrates with germinal centers, thyroid acinar atrophy and pituitary cell hyperplasia/hypertrophy of the adenohypophysis was detected in a vehicle control, 4-year-old female Cynomolgus macaque in a routine toxicology study. Lymphoid cells of germinal centers were positive for the B-cell marker CD20 by immunohistochemistry (IHC), while remaining lymphocytes were positive for the T-cell marker CD3. Hypertrophied/hyperplastic pituitary cells were positive for thyroid stimulating hormone (TSH) by IHC, consistent with an adaptive response due to removal of hormonal negative feedback from the diseased thyroid gland. Features of this case are similar to chronic lymphocytic thyroiditis in humans, an autoimmune disorder also known as Hashimoto's disease. Chronic lymphocytic thyroiditis with compensatory pituitary changes may occur spontaneously in young, clinically normal cynomolgus macaques and its presence in drug treated animals should be interpreted with caution.

    Recently, reduced Nasal nitric oxide (nNO) nNO levels have been reported in children with adenoidal hypertrophy predisposing to chronic nasosinusal inflammation. Given the strict anatomic and physiopathologic link between the nasopharyngeal and middle ear compartments, and considering the high prevalence of otitis prone children among those affected with chronic adenoiditis, we designed a study aimed to test any possible difference in nNO levels between non-allergic children with and without recurrent acute otitis media (RAOM) associated with chronic adenoiditis. The study involved 54 children with RAOM (44.4% males; mean age= 7.5±3.5 years) and 51 children without RAOM (47.4% males; mean age= 7.0±3.8 years). nNO levels were significantly reduced in children with RAOM compared to children without RAOM (676.9±250.7 ppb vs 831.8±320.4 ppb, respectively; p= 0.02). Our results could be related to reduced NO production by the ciliated paranasal, nasopharyngeal and middle ear epithelium and the impaired sinusal ostial and Eustachian tube patency due to chronic inflammation, and seem to confirm the involvement of NO pathway in recurrent upper airway infections related to impaired ciliated respiratory mucosa.

    Full Text Available Breast cancer occurring in women under the age of 40 is uncommon in the absence of family history or genetic predisposition, and prompts the exploration of other possible exposures or environmental risks. We report a case series of four young women—ages from 21 to 39—with multifocal invasive breast cancer that raises the concern of a possible association with nonionizing radiation of electromagnetic field exposures from cellular phones. All patients regularly carried their smartphones directly against their breasts in their brassieres for up to 10 hours a day, for several years, and developed tumors in areas of their breasts immediately underlying the phones. All patients had no family history of breast cancer, tested negative for BRCA1 and BRCA2, and had no other known breast cancer risks. Their breast imaging is reviewed, showing clustering of multiple tumor foci in the breast directly under the area of phone contact. Pathology of all four cases shows striking similarity; all tumors are hormone-positive, low-intermediate grade, having an extensive intraductal component, and all tumors have near identical morphology. These cases raise awareness to the lack of safety data of prolonged direct contact with cellular phones.

    The emergence of high efficiency photovoltaic cells is leading the industry into using solar concentrators in order to reduce costs by decreasing the number of cells used. In this paper Optics department of Universidad Complutense de Madrid has designed a multifocal Fresnel lens of PMMA and has studied the main parameters that have influence on its final function. This has been done by taking into account its manufacturing tolerances. The lens is square shaped with sides measuring 270 mm and it is composed of three different zones based on three different criteria: The central zone has been designed by using paraxial formulation, the intermediate one has been designed based on Fresnel classical formula while the marginal zone's purpose is to deflect the light by total internal reflection on prism faces. All three zones have different focal areas and different optical axis so the energy distribution will be more uniform whilst avoiding cell damage caused by hot spots. The design stage is feedback through simulations using a ray tracer software. In order to characterize the lens operation a measure of optical concentration was first taken on different lens areas using an integrating sphere. Finally, the lens performance in terms of concentration and in terms of uniformity at the focal spot was studied by processing the images taken with a CCD camera on a screen placed at the focal plane of the lens.

    The aim of this study is to correlate multifocal electroretinogram (mfERG) and visual evoked potential (VEP) changes with visual acuity and clinical features in patients with posterior segment inflammation secondary to syphilis. A retrospective interventional case series of 4 patients with visual loss secondary to syphilitic uveitis is reported. The mfERG (P1) showed diminished amplitudes and prolonged latency in 7 affected eyes. Visual acuity rapidly improved 2 weeks after initiation of therapy. OCT demonstrated anatomical recovery at 1 month. In three patients, visual acuity was restored to 6/6 at 6-9 months but mfERG responses remained significantly reduced and delayed for 12-15 months before recovery to normal levels. One patient developed a retinal detachment, but achieved 6/9 vision at 30 months. VEP changes, interpreted in combination with mfERG responses, showed evidence of optic nerve involvement in 6 eyes. Ocular findings, including posterior placoid chorioretinitis, are important diagnostic features of secondary and tertiary syphilis. Visual acuity and clinical recovery occur early with appropriate diagnosis and treatment, and precede full electrophysiological recovery of the outer retina-RPE complex. Ophthalmologists have the opportunity to play a key role in undetected or missed diagnoses of syphilis, and with appropriate treatment the visual prognosis is excellent.

    Progressive multifocal leukoencephalopathy is a demyelinating disease with a high mortality caused by the JC virus and occurs in about 5% of HIV-infected patients. Highly active anti-retroviral therapy (HAART) has a proven efficacy in prolonging the survival of patients with AIDS-associated PML, but there are differing opinions about adding cidofovir to the treatment of PML. To investigate the benefit of HAART combined with cidofovir, we retrospectively analysed the survival of 33 patients with AIDS-associated PML proven by PCR in CSF, biopsy or at autopsy. Additionally, we also analysed 37 patients with probable PML. Seventeen (51.5%) of the patients with confirmed PML were treated with HAART and 14 (42.4%) with cidofovir in any combination. Of these patients, 13 (39.4%) were treated with HAART and cidofovir in combination, four (12.1%) patients received only HAART without cidofovir and one (3%) patient received only cidofovir without HAART. Fifteen patients did not receive HAART or cidofovir. The cumulative survival was significantly longer in patients with HAART than in patients without HAART (p = 0.006), independent whether cidofovir was given or not. In comparison with single therapy with HAART, the combination of HAART and cidofovir showed no significant increase in survival (p = 0.435). Therefore, a benefit for cidofovir in addition to HAART in the treatment of PML in HIV-infected patients could not be proven.

    Introduccion. La epiteliopatia pigmentaria placoide multifocal posterior aguda (EPPMPA) es una enfermedad inflamatoria rara, generalmente de etiologia indeterminada, de la coriocapilar, el epitelio pigmentario y la retina externa. Afecta predominantemente a pacientes jovenes y en algunos casos puede involucrar al sistema nervioso central en forma de ictus o de meningoencefalitis. Presentamos el caso clinico de una mujer joven con EPPMPA complicada con ictus e hipertension intracraneal. Caso clinico. Mujer de 16 anos que comienza con cefalea intensa sugestiva de hipertension intracraneal, asi como con un deficit agudo hemisferico izquierdo. La resonancia magnetica craneal ponia de manifiesto lesiones embolicas o vasculiticas en diferentes territorios. No se evidenciaron datos de meningoencefalitis en el estudio del liquido cefalorraquideo, pero si de hipertension intracraneal asociada. La presencia de lesiones muy especificas en el polo ocular posterior permitio el diagnostico de EPPMPA complicada con ictus isquemico, probablemente por mecanismo vasculitico. Un amplio estudio etiologico fue negativo para identificar un factor desencadenante claro del proceso. Se inicio tratamiento corticoideo con buena evolucion clinica y radiologica. Conclusiones. La EPPMPA es una entidad rara que generalmente entrana buen pronostico; sin embargo, en algunos casos puede complicarse con afectacion del sistema nervioso central, y el ictus isquemico secundario a vasculitis es la complicacion mas grave. Ante un paciente joven con ictus que presente sintomatologia visual y lesiones coriorretinianas, debe considerarse la EPPMPA en su diagnostico etiologico.

  20. Progressive Multifocal Leukoencephalopathy in a 62-Year-Old Immunocompetent Woman

    Full Text Available Progressive multifocal encephalopathy (PML is a rare demyelinating disease that typically presents in immunodeficient patients. We report a case of a previously healthy 62-Year-Old woman who suffered from an unsteady gait, throbbing headaches, and progressive left-sided weakness and numbness. Stroke was initially suspected based on imaging and symptoms. A series of follow-up magnetic resonance images of the brain showed a right parietal lesion growing in size as the patient became unable to walk and experienced increasing lethargy and confusion. A biopsy of the lesion was positive for the John Cunningham virus (JCV. A diagnosis of PML was made and she was started on mefloquine. No improvement was seen on this treatment and her condition worsened. Although PML remains uncommon in immunocompetent individuals, it cannot be ruled out based on their immune status. Although the exact cause remains uncertain, underlying or transient states of immunosuppression may be responsible for reactivation of the JCV in these patients.
