    Cutis laxa is a rare disease characterized by abnormal skin wrinkling and laxity, due to decreased elastin synthesis or structural extracellular matrix defects. We have explored elastin metabolism in a case of adult onset cutis laxa localized to the upper body of a woman. For this purpose, we obtained skin biopsies from affected and unaffected skin areas of the patient and analyzed these with microscopy, polymerase chain reaction, western blotting and cell culture experiments. Skin from the affected area lacked elastin fibers in electron microscopy but had higher mRNA expression of elastin and total RNA. Levels of an apparent tropoelastin degradation product were higher in the affected area. Fibroblast cultures from the affected area were able to produce elastin and showed higher proliferation and survival after oxidative and UVB stress compared to fibroblasts from the unaffected area. In conclusion, we report a case of acquired localized cutis laxa with a lack of elastic fibers in the skin of the patient's upper body. The lack of elastic fibers in the affected skin was combined with increased mRNA expression and protein levels of elastin. These findings indicate that elastin synthesis was increased but did not lead to deposited elastic fibers in the tissue.

    Vashi, Neelam; Chu, Julie; Patel, Rishi

    2011-10-15

    Plate-like osteoma cutis is a rare disorder that has been historically classified as a congenital syndrome. It has a possible relationship to a mutation in the gene (GNAS1) that encodes the α-subunit of the stimulatory G protein, which regulates adenyl cyclase activity. We report a case of extensive plaque-like masses on the scalp and face with no abnormalities in calcium or phosphate metabolism and no preceding inflammatory cutaneous conditions. With less than ten reported cases, to our knowledge, this is one the few cases of acquired plate-like osteoma cutis described in the literature.

    Objective. The aim of this case report was to present our patient suffering from CL, and to evaluate clinical presentation, diagnostic and therapeutic difficulties in this rare condition. Case Report. A 30-year-old female patient was admitted to our Hospital due to localized loose and sagging skin of abdomen, induced by prior cesarean section 6 years ago. CL has been diagnosed based on the clinical picture and pathohistological appearance. Conclusion. Reconstructive surgery provides a dramatic cosmetic improvement with significant psychosocial benefit. Repeated surgical procedures may be required to correct the lax skin, which worsens with age.

    Cho, S Y; Maguire, R F

    1980-08-01

    Acquired cutis laxa is a rare disorder characterized by diffuse laxity of the skin and loss of connective tissue support with involvement of the lungs, gastrointestinal tract, pelvic organs, and aorta. The case report presented herein describes a forty-six year old woman with multiple myeloma and cutis laxa. Her history included several severe allergic reactions and the gradual development of lax skin, loss of connective tissue support throughout the body, and emphysema. At autopsy, multiple myeloma, diffuse laxity of the skin, and panacinar emphysema were found. The amount of elastic fiber in the skin, lungs, and aorta was decreased and showed abnormal fragmentation. Results of direct immunofluorescence study demonstrated IgG bound to dermal elastic fibers. Speculation regarding an immunologic etiology of the elastic tissue abnormality is presented herein.

    2004-01-01

    Full Text Available Acute febrile neutrophilic dermatosis (AFND, commonly known as Sweet’s syndrome, is a disorder seen in adult females, being extremely rare in children. Typical features include spiky fever, sudden eruption of raised painful erythematous to plum-colored nodules and plaques, neutrophilic leucocytosis, a dermal neutrophili infiltrate an a rapid response to systemic steroid. The eruption is believed to represent a hypersensitivity reaction to an antecedent infection or malignancy. There have been rare reports of acquired cutis laxa (Marshall’s syndrome following Sweet’s syndrome. We report one such case of Sweet’s syndrome leading to acquired cutis laxa (Marshall’ syndrome in a child.

    2009-06-01

    Cutis laxa (CL) is an inherited or acquired connective tissue disorder characterized clinically by loosely hanging skin folds. There is often preceding cutaneous inflammatory eruption (ie, urticaria, eczema, erythema multiforme), and there is frequently internal organ involvement of the gastrointestinal, urogenital, pulmonary, and cardiovascular systems. Histologically, there are degenerative changes in the dermal elastic fibers. Of the few reports on this rare disorder, authors have speculated about an immune-mediated destruction of elastic fibers, and monoclonal gammopathies, such as multiple myeloma or heavy chain deposition disease, have a recognized association with CL. We report an unusual case of rapidly progressing acquired CL associated with leukocytoclastic vasculitis, IgA myeloma, and an immune complex-mediated glomerulonephritis. Light microscopy of the lax skin revealed complete absence of elastic fibers in areas of vasculitis.

    2013-01-01

    Full Text Available Cutis laxa is a rare disease that may be either inherited or acquired. The acquired form is rarer than the inherited form. Pathogenesis of this disease is largely unknown. Two cases of acquired cutis laxa are reported here and neither of them had any systemic involvement or any history of drug intake. One of them had localized disease with history of preceding cutaneous inflammation. The other patient with generalized lesion lacked any history of preceding illness. The patient with localized lesion was treated satisfactorily by reconstructive surgery. The other patient had generalized involvement, for which no satisfactory treatment could be offered.

    Full Text Available Leukemia cutis is the infiltration of neoplastic leukocytes or their precursors into the epidermis, the dermis, or the subcutis, resulting in clinically identifiable cutaneous lesions. Leukemia cutis may follow, precede or occur concomitantly with the diagnosis of systemic leukemia. A 50-year-old woman presented with asymptomatic multiple cutaneous nodules all over the body of 4 months duration. Cutaneous examination showed multiple hyperpigmented nodules and plaques involving face, trunk, and extremities. Peripheral smear showed abnormally elevated leucocyte count (TLC-70,000 with abnormal cells: myeloblasts 40%, promyelocytes 8% and myelocytes 39%. Auer rods were present in few myeloblasts. Bone marrow aspiration showed increased cellularity, erythroid hyperplasia with megaloblastic change, increased myeloblasts with maturation arrest. Immunohistochemistry showed strongly positive myeloperoxidase infiltrating cells and negative for CD20 and CD3 consistent with the diagnosis of AML-M 2 with leukemia cutis. This case is reported for its rarity.

    Full Text Available Patients with leukemia may show involvement of the skin. This skin involvement can be due to infiltration of skin by leukemic cells or it may be a part of nonspecific cutaneous manifestations. Leukemia cutis is the infiltration of neoplastic leucocytes or their precursors into the skin resulting in extensive clinical manifestations. Described mostly in acute myeloid leukemia and acute myelocytic monocytic leukemia, it is rare in chronic myeloid leukemia and is seen mostly during the blast crises. Its presence signals poor prognosis.

    Full Text Available Leiomyomatosis cutis is a rare disease characterized by oval shaped, red-brown follicular groups of papulonodular lesions especially located on the lower limbs, in which the lesions originate from smooth muscle cells. A fifty-three-year-old female patient was admitted to our clinic with multiple painful nodules on the body. An ischemic stroke, total hysterectomy for leiomyoma, oopherectomy, nephrolitiasis and renal cysts were present in her past medical history. Dermatologic examination revealed multiple, painful, red-brown nodules forming clusters on the left scapular area, bilateral gluteal area and lower limbs. Histopathological examination of the lesional biopsy diagnosed as leiomyoma. Treatment started with gabapentin, paracetamol, tramadol hydrochloride and, amitriptyline, which produced relief of the pain at the end of three weeks. To the best of our knowledge, this is the first case report in our country.

    Full Text Available Osteoma cutis (cutaneous ossification (OC is a rare disorder with true bone formation within the skin. Multiple miliary osteoma cutis of the face (MMOCF is a cause of acquired OC, is characterized by multiple, small, and primary osteomas in the skin tissue of the face and is a benign extraskeletal and rare bone formation. To date, 52 cases with MMOCF have been reported in the literature. Herein, we report a 56-year-old female patient presented with multiple small, firm, skin-colored papules on the forehead and face lasting for 4 years. She had no history of preexisting acne or any local inflammatory disease at the lesional sites. The skin biopsy revealed osteoid formation with central degeneration and calcification in the dermis. Depending on these clinical and histopathological findings, the patient was diagnosed as MMOCF.

    2013-05-01

    Full Text Available Calcinosis cutis is an uncommon disorder characterized by deposition of insoluble calcium salts in the skin. Based on the etiology of the deposition calcinosis cutis may be devided into four major groups namely metastatic, dystrophic, idiopathic, and iatrogenic. The pathophysiology of calcinosis cutis remains unclear. The dystrophic form is the most common whereas the idiopathic one is the rarest. Idiopathic calcinosis cutis occurs in the absence of any identifiable causes and is not associated with drug use. Idiopathic calcinosis cutis has two major types called localized (circumscript and generalized (universalis. Localized type generally involves the vulva, scrotum, penis and breast. A definitive diagnosis requires the histologic demonstration of the accumulation of calcium in the skin and exclusion of other clinic types.There is not an effective treatment for the disease. A 47-year-old woman referred to our outpatient clinic for painless, yellowish-white nodules on her hand enduring for 30 years. A diagnosis of idiopathic calcinosis cutis was made by clinical and histological findings. We present this case because localization of lesions in our case was previously unreported in the literature to our knowledge.

    Hypertrichosis is the excessive hair growth in any area of the skin surface. Acquired localized hypertrichosis may be secondary to multiple causes and there is a secondary form due to several drugs, which is usually reversible with discontinuation of the causative agent. Rivastigmine is a reversible and competitive inhibitor of acetylcholinesterase and butyrylcholinesterase used for symptomatic treatment of Alzheimer dementia and Parkinson's disease. It has an adequate safety profile and cutaneous side effects are unusual. Irritant contact dermatitis, allergic dermatitis, baboon syndrome, and cutaneous rash due to rivastigmine have been reported. We report on a Caucasian 80-year-old male with personal history of Alzheimer's disease. The patient started therapy with oral rivastigmine one month prior to clinical presentation of localized hypertrichosis on both forearms. Norgalanthamine has been shown to promote hair growth activity via the proliferation of dermal papilla. Acetylcholinesterase inhibitors can induce hair growth. PMID:27073702

    Cutis laxa (CL) is a heterogeneous group of inherited and acquired connective tissue disorders characterized by a loose skin and variable systemic involvement (inguinal hernia, cardiopulmonary disease, and emphysema). Autosomal dominant, autosomal recessive and x-linked recessive patterns have been described in the inherited forms. Acquired forms of this disease have been associated with a previous inflammatory skin disorder (urticaria…). The characteristic symptomatological pattern is resulting from paucity of elastic fibers. We report an 18 months old baby boy with a congenital cutis laxa. He was admitted in pediatric unit for respiratory disorders. The diagnosis of CL syndrome is based on clinical assessment of typical skin features and the associated extracutaneous finding. PMID:25995800

    Directory of Open Access Journals (Sweden)

    Derya Alabaz

    2009-08-01

    Full Text Available Calcinosis cutis is an uncommon disorder characterized by the progressive deposition of crystals of calcium phosphate (hydroxyapatite in the skin in various areas of the body. It is classified into four types according to etiology, namely as dystrophic if calcium and phosphorus levels are normal and tissue damage is present, as idiopathic if calcium and phosphorus levels are normal and no tissue damage is present, or as metastatic if there is hypercalcemia or hyperphosphatemia. Medical and surgical treatments are options to cure calcinosis cutis. Medical therapy is not very effective. Surgical excision has shown to be beneficial, as it can provide a symptomatic relief. However, since calcinosis cutis limits are not always well defined, a recurrence of the lesions may occur. We dealt with a very rare form of calcinosis cutis in a healthy 6-year-old girl. There was no evidence of connective tissue disorder or abnormal mineral metabolism. Hence, she was diagnosed as idiopathic calcinosis cutis and, although calcifications in idiopathic cutis are most commonly localized to one area, our patient unusually exhibited widespread calcific deposits. Although the existing lesions showed slow improvement, systemic pamidronate therapy was effective in preventing the occurrence of new lesions. Surgical excision proved to be an effective and successful treatment. This report aims to raise doctors’ awareness on the presentation, etiopathogenesis, and course of the relatively rare idiopathic calcinosis cutis.

    Full Text Available AB STRACT: Tuberculosis verrucosa cutis, otherwise called as warty tuberculosis is a disease due to acquired infection from an exogenous source in a person who has moderate to high immunity for tuberculosis. Lesions are frequently reported on hands and lower limbs. It is an occupational hazard in people who handle tuberculous tissues during work, example: Veterinarians and mortuary at tenders, farmers, butchers, anatomy at tenders (anatomist’s warts. Auto inoculation by sputum in a pulmonary tuberculosis pati ent can cause the disease. Clinical features are variable, but verrucosity always forms. Lesions are usually single indurated, verrucous plaque with serpigenous edge which may show some scar at centre with keloidal changes and are seen at trauma prone site s. Histopathology shows psedoepitheliomatous hyperplasia with infiltration of plasma cells and sometimes with caseating granuloma. Tissues rarely show positivity to bacilli on staining. Treatment of the disease is by anti TB therapy which will completely resolve the lesion.

    Osteoma cutis is the aberrant development of bone within the skin. The bone formation may be de novo (primary) or result from an injury to the skin (secondary). Here we present a healthy 53-year-old man with no known abnormalities in calcium or phosphate metabolism with plate-like osteoma cutis of the scalp. Plate- or plaque-like osteoma cutis was initially described as a congenital condition but has now been reported several times in the literature as an idiopathic process that occurs in adults. Treatment options are limited and are only required if the lesion is bothersome to the patient.

    Hyalinosis cutis et mucosae is a rare autosomal recessive disorder which is characterized by deposition of hyaline material around the basement membrane of the skin and mucous membranes. Typical clinical symptoms are hoarseness, infiltration of the mucous membranes and papular verrucous skin changes. Mutations within the extracellular matrix protein gene (ECM-1) are the underlying defect. We report on a 24-year-old man, who had first been seen in our department at the age of seven and had undergone the necessary diagnostic procedures and who revisited 17 years later with hoarseness and extensive verrucous skin changes at elbows and knees which were removed by excision. A new mutation of the ECM1 gene was identified.

    Full Text Available Cutis laxa is a rare skin disorder, characterized by redundant, inelastic and with an appearance of premature aging. It can be associated with the alteration of other organs involved in their prognosis. It can be inherited or acquired form, local or generalized. It has an estimated incidence of 1 in 1,000,000 births. Genetic studies have discovered a gene network growing required for biogenesis of the elastic fiber in the extracellular matrix and its involvement in the homeostatic maintenance of this integral component of the dermal connective tissue may be involved in the pathophysiology of this entity. We present a case of a child, product of consanguineous marriage with clinical and histopathological diagnosis of cutis laxa with autosomal recessive inheritance pattern.

    2006-08-01

    Haemophilus ducreyi causes the sexually transmitted genital ulcer disease chancroid. In human inoculation experiments, bacteria colocalize with neutrophils and macrophages but remain extracellular. The organism also colocalizes with collagen and fibrin but not with keratinocytes, fibroblasts, laminin, or fibronectin. These relationships are established by 48 h postinoculation and persist through the pustular stage of disease. To extend these observations to the ulcerative stage of disease, and to compare results in the human model with those of natural disease, we obtained biopsies from patients with naturally acquired chancroid. All ulcers were culture positive for H. ducreyi and histologically very similar to pustules from the human model. Staining with H. ducreyi-specific monoclonal antibodies demonstrated H. ducreyi within 5 biopsies. The organism was chiefly found within the granulocytic infiltrate of the ulcer. Dual staining for H. ducreyi and eukaryotic tissue components showed that H. ducreyi colocalized with neutrophils and fibrin at the ulcerative stage of disease. No bacteria were associated with keratinocytes, fibroblasts, or collagen. Overall, these findings are consistent with results from the human model. This is the first reported study to localize bacteria specifically identified as H. ducreyi within naturally acquired chancroid.

    Full Text Available We describe a 16-year-old boy whose left forearm and hand were cut by a piece of glass from a broken window as a result of the fall. He had surgical repair of his left extensor pollicis brevis, abductor pollicis brevis, and dorsal branch of the left radial nerve. Following the surgery, he was put on a splint so as to immobilize the left forearm and wrist. On removal of the splint 4 weeks post surgery, he was noticed to have more hair growth on his left forearm and hand than his right counterparts. The patient was reassessed 2, 4, and 8 months after the removal of the splint. The hypertrichosis got better with time. At the last visit, the hair growth in the left forearm and hand was back to normal. Our patient represents the first reported case of localized acquired hypertrichosis following the application of a splint in the pediatric literature.

    2013-01-01

    Full Text Available Calcinosis cutis is an uncommon disorder caused by an abnormal deposit of calcium phosphate in the skin in various parts of the body. Four main types of calcinosis cutis have been recognized according to etiology: associated with localized or widespread tissue changes or damage (dystrophic calcification, that associated with an abnormal calcium and phosphorus metabolism (metastatic calcification, not associated with any tissue damage or demonstrable metabolic disorder (idiopathic calcification, and Iatrogenic. Very few cases of idiopathic calcinosis cutis are reported in early childhood in the literature. We report one such case of idiopathic calcinosis cutis over elbow in a 12-year-old female child. Histological examinations of the lesions resected in this case reveal calcium deposits in the dermis, surrounded by foreign body giant cells. Idiopathic calcinosis cutis is a rare phenomenon and occurs in the absence of known tissue injury or systemic metabolic defect. It is important to delineate it from other calcification disorders for further plan of management. Medical therapy in calcinosis cutis is of limited benefit in pediatric age group and poses a challenging problem of postsurgical management.

    Full Text Available Cutis laxa is a heterogeneous condition characterized by redundant, sagging, inelastic, and wrinkled skin. The inherited forms of this disease are rare and can have autosomal dominant, autosomal recessive, or X-linked inheritance. Three of the autosomal recessive cutis laxa syndromes, namely cutis laxa IIA (ARCL2A, cutis laxa IIB (ARCL2B, and geroderma osteodysplastica (GO, have very similar clinical features, complicating accurate diagnosis. Individuals with these conditions often present with cutis laxa, progeroid features, and hyperextensible joints. These conditions also share additional features, such as short stature, hypotonia, and congenital hip dislocation, but the severity and frequency of these findings are variable in each of these cutis laxa syndromes. The characteristic features for ARCL2A are abnormal isoelectric focusing and facial features, including downslanting palpebral fissures and a long philtrum. Rather, the clinical phenotype of ARCL2B includes severe wrinkling of the dorsum of the hands and feet, wormian bones, athetoid movements, lipodystrophy, cataract and corneal clouding, a thin triangular face, and a pinched nose. Normal cognition and osteopenia leading to pathological fractures, maxillary hypoplasia, and oblique furrowing from the outer canthus to the lateral border of the supraorbital ridge are discriminative features for GO. Here we present 10 Iranian patients who were initially diagnosed clinically using the respective features of each cutis laxa syndrome. Each patient’s clinical diagnosis was then confirmed with molecular investigation of the responsible gene. Review of the clinical features from the cases reported from the literature also supports our conclusions.

    Bullous leukemia cutis is an uncommon clinical manifestation of cutaneous infiltration by leukemic cells, from B-cell chronic lymphocytic leukemia. We present the case of a 67-year-old, female, chronic lymphocytic leukemia patient. She was taking chlorambucil and developed facial edema with erythema and warmth, misjudged as facial cellulitis. Two days later, she developed bullous lesions in the arms, legs, neck and face. The histopathology of facial and bullous lesions confirmed leukemia cutis. All lesions disappeared following the administration of rituximab combined with cycles of fludarabine and cyclophosphamide. Although soft tissue infections are common complications in patients undergoing chemotherapy, leukemia cutis can also resemble cellulitis. PMID:27192532

    We describe a mission concept for the Cubesat Ultraviolet Transient Imaging Experiment (CUTIE). CUTIE will image an area on the sky of ~ 1700 square degrees every ~ 95 min at near-UV wavelengths (260-320 nm) to a depth of 19.0 mag (AB). These capabilities represent orders of magnitude improvement over past UV imagers, allowing CUTIE to conduct the first true synoptic survey of the transient and variable sky in the UV bandpass. CUTIE will uniquely address key Decadal Survey science questions such as how massive stars end their lives, how super-massive black holes accrete material and influence their surroundings, and how suitable habitable-zone planets around low-mass stars are for hosting life. By partnering with upcoming ground-based time-domain surveys, CUTIE will further leverage its low-Earth orbit to provide a multi-wavelength view of the dynamic universe that can only be achieved from space. The remarkable sensitivity for such a small payload is achieved via the use of large format delta-doped CCDs; space qualifying this technology will serve as a key milestone towards the development of future large missions (Explorers and Surveyors). Finally, our innovative design in a 6U cubesat form factor will enable significant cost savings, accelerating the timeline from conception to on-sky operation (5 years; well matched for graduate student participation).

    2005-01-01

    An 11-year-old girl had multiple, disseminated, rather small café-au-lait macules and hypochromic spots involving the neck, the trunk and the legs. In part, the two types of macules showed a spatial proximity, suggesting didymosis (twin spotting). The term cutis tricolor has been proposed to describe congenital paired hyperchromic and hypochromic macules on a background of intermediate skin. Because the spots present in this case were much smaller than those described in previous cases of cutis tricolor, we here propose the distinguishing term 'cutis tricolor parvimaculata'. The underlying gene locus may be a hot spot for postzygotic recombinations, giving rise to multiple twin spots. Moreover, the girl had developed seizures from the age of 10 years, and a large oligodendroglioma involving the left frontal lobe was found. A causal relationship between the cutaneous phenotype and the cerebral tumor is unproven but likely. The skin lesions were reminiscent of a disorder described by Westerhof et al. in 1978 under the term 'hereditary congenital hypopigmented and hyperpigmented macules'. So far, however, it is not clear whether cutis tricolor parvimaculata is identical with or different from this disorder. (c) 2005 S. Karger AG, Basel

    Cutis laxa (CL) is an extremely inherited or acquired connective tissue disorder characterised by a markedly reduced systemic elastin content. Genital abnormalities in patients with CL have been rarely reported. We report such a case in a 48-year-old CL patient affected by genital prolapse, focusing on immunohistological and molecular biology assessment of elastin and collagen type I, III, VI content in the main uterine ligaments. The woman was referred to our department for the onset of a rapidly progressing genital prolapse and urinary incontinence. The patient underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy and sacrocolpopexy. Punch biopsies from both cardinal and uterosacral ligaments revealed a dramatic reduction in elastin and an increase in collagen type VI content. The present report seems to underline the central role exerted primarily by elastin in the supportive connective tissue and might contribute to the knowledge of extracellular matrix abnormalities at the basis of genital abnormalities in CL patients.

    Full Text Available Hypocalcemia most frequently occurs in premature neonates. It is usually treated by intravenous (iv calcium supplementation. However, complications caused by extravasation of iv calcium gluconate include localized soft tissue calcification, necrosis, cellulitis, osteomyelitis, and even compartment syndrome. We present a rare case of iatrogenic calcinosis cutis complicated by compartment syndrome secondary to extravasation of iv calcium gluconate in a neonate. Emergent fasciotomy was performed twice for decompression of compartment syndrome. Histologic findings revealed necrosis and calcification. Appropriate antibiotics were administered to control secondary infection. To the best of our knowledge, there were no previous case reports of calcinosis cutis with compartment syndrome in infants. Although iatrogenic calcinosis cutis is generally a benign entity, the early recognition of the presentation of extravasation of calcium gluconate is important to avoid severe complications and possible medical malpractice disputes. This report aims to raise doctors' awareness of the presentation, course, and management of this relatively rare iatrogenic complication.

    Autosomal recessive cutis laxa (ARCL) describes a group of syndromal disorders that are often associated with a progeroid appearance, lax and wrinkled skin, osteopenia and mental retardation. Homozygosity mapping in several kindreds with ARCL identified a candidate region on chromosome 17q25. By high-throughput sequencing of the entire candidate region, we detected disease-causing mutations in the gene PYCR1. We found that the gene product, an enzyme involved in proline metabolism, localizes to mitochondria. Altered mitochondrial morphology, membrane potential and increased apoptosis rate upon oxidative stress were evident in fibroblasts from affected individuals. Knockdown of the orthologous genes in Xenopus and zebrafish led to epidermal hypoplasia and blistering that was accompanied by a massive increase of apoptosis. Our findings link mutations in PYCR1 to altered mitochondrial function and progeroid changes in connective tissues.

    Cutis verticis gyrata (CVG) is a skin condition characterized by thick folds and deep furrows, resembling a cortical gyral pattern. There is a recognized but rare association with Noonan syndrome. We report the antenatal imaging, including three-dimensional surface-rendered sonography and MRI, of a fetus with CVG who was subsequently diagnosed with Noonan syndrome. The case illustrates the antenatal appearances of congenital CVG and the potential yield of antenatal imaging in excluding a major central nervous system anomaly. This is important because without prior knowledge of this condition and its imaging characteristics, it is possible to get a false impression of an underlying skull defect on mid-trimester imaging.

    Full Text Available Melioidosis is caused by Burkholderia pseudomallei, a Gram-negative bacillus, primarily found in soils in Southeast Asia and northern Australia. A recent case of melioidosis in non-endemic Arizona was determined to be the result of locally acquired infection, as the patient had no travel history to endemic regions and no previous history of disease. Diagnosis of the case was confirmed through multiple microbiologic and molecular techniques. To enhance the epidemiological analysis, we conducted several molecular genotyping procedures, including multi-locus sequence typing, SNP-profiling, and whole genome sequence typing. Each technique has different molecular epidemiologic advantages, all of which provided evidence that the infecting strain was most similar to those found in Southeast Asia, possibly originating in, or around, Malaysia. Advancements in new typing technologies provide genotyping resolution not previously available to public health investigators, allowing for more accurate source identification.

    Objective. To evaluate the diagnostic criteria for the localization of acquired arteriovenous fistulas (AVFs)by color Doppler flow imaging (CDFI) based on the features of their hemodynamic changes.Methods. The shape and hemodynamic changes of involved vessels which could be helpful to localize thesites of fistulas were studied according to the observation of 10 cases of acquired AVFs.Results. The s tes of the fistulas could be shown by two-dimensional ultrasonography and color flow imagingin 40% and 80% tases, respectively. In all cases, turbulent high-velocity flow was present at the sites of thefistulas, low resistant flow was present in the arteries proximal to the fistulas, and artery-like flow was detected inthe veins.Conclusion. C OFt was accurate for the localization of acquired AVFs, which were mainly localized by theirhemodynamic changes shown by pulse Doppler ultrasound.``

    Full Text Available Introduction . Dermatitis herpetiformis is a rare bullous disorder. Autoimmunological disturbances associated with hypersensitivity to gluten play the main role in the etiopathogenesis of the disease. Clinical manifestations include polymorphic skin lesions which may cause diagnostic difficulties. Objective. To present a case of dermatitis herpetiformis diagnosed and treated without any clinical improvement as tinea cutis glabrae. Case report . A 20-year-old male patient was admitted for the evaluation of polymorphic skin lesions of 7-month duration distributed symmetrically on the skin of elbows, knees, face and the gluteal and sacral region. The patient was previously treated with systemic and topical antimycotic drugs. Due to a typical distribution of skin lesions as well as symptoms reported by the patient, we started to suspect Duhring’s disease. The diagnosis was confirmed by direct immunofluorescence of skin biopsy and serological tests. Systemic treatment with dapsone and a gluten-free diet led to clinical improvement. Conclusions . The morphology and localization of skin lesions in Duhring’s disease may be similar to the clinical presentation of fungal infection of the skin, which in equivocal cases should be excluded by a mycological test.

    We report the occurrence of calcinosis cutis in a 3-year-old girl after liver transplantation. The cutaneous lesions consisted of 5 mm white papules on an erythematous base in linear and rosette configurations that developed in the abdominal and lumbar areas 10 days after transplantation. The patient had received calcium chloride solution intravenously during surgery. We excluded other causes of ectopic calcification such as hyperparathyroidism, renal failure, and extravasation of calcium solution. We discuss the etiology of calcinosis cutis after liver transplantation. This sequence of events has not been previously described in pediatric patients.

    Full Text Available Dengue has been a major public health concern in Australia since it re-emerged in Queensland in 1992-1993. We explored spatio-temporal characteristics of locally-acquired dengue cases in northern tropical Queensland, Australia during the period 1993-2012.Locally-acquired notified cases of dengue were collected for northern tropical Queensland from 1993 to 2012. Descriptive spatial and temporal analyses were conducted using geographic information system tools and geostatistical techniques.2,398 locally-acquired dengue cases were recorded in northern tropical Queensland during the study period. The areas affected by the dengue cases exhibited spatial and temporal variation over the study period. Notified cases of dengue occurred more frequently in autumn. Mapping of dengue by statistical local areas (census units reveals the presence of substantial spatio-temporal variation over time and place. Statistically significant differences in dengue incidence rates among males and females (with more cases in females (χ(2 = 15.17, d.f.  = 1, p<0.01. Differences were observed among age groups, but these were not statistically significant. There was a significant positive spatial autocorrelation of dengue incidence for the four sub-periods, with the Moran's I statistic ranging from 0.011 to 0.463 (p<0.01. Semi-variogram analysis and smoothed maps created from interpolation techniques indicate that the pattern of spatial autocorrelation was not homogeneous across the northern Queensland.Tropical areas are potential high-risk areas for mosquito-borne diseases such as dengue. This study demonstrated that the locally-acquired dengue cases have exhibited a spatial and temporal variation over the past twenty years in northern tropical Queensland, Australia. Therefore, this study provides an impetus for further investigation of clusters and risk factors in these high-risk areas.

  5. The diagnostic dilemma of cutis laxa: A report of two cases with genotypic dissimilarity

    Directory of Open Access Journals (Sweden)

    Manisha Goyal

    2015-01-01

    Full Text Available Cutis laxa is a heterogeneous group of diseases, with loose, wrinkled skin folds and hyperelasticity of the skin. There are overlapping of clinical features of the group of syndrome associated with cutis laxa, including congenital cutis laxa, wrinkly skin syndrome and gerodermia osteodysplastica. All these conditions present a challenge to the clinician. Thus, molecular diagnosis is the only way to resolve these phenotypically similar conditions. We hereby describe two Indian patients with wrinkled skin and mild craniofacial dysmorphic features who had molecular confirmation of autosomal recessive cutis laxa.

    Full Text Available A two-month-old female infant born of a consanguineous marriage, presented with loose, wrinkled and inelastic skin over the neck, axillae, trunk, inguinal region and thighs with slow elastic recoil. Patient also had systemic manifestations in the form of bilateral apical lobe consolidation of lung, bilateral inguinal hernia, rectal and uterovaginal prolapse. Histopathological examination of skin biopsy with special stain for elastic tissue revealed absence of dermal elastic tissue. Genital abnormalities in patients with congenital cutis laxa have been reported rarely. But rectal and uterovaginal prolapse have not been reported at an early age of two months. In the absence of mutational screening, with history and clinical findings our case is likely to be Type I autosomal recessive form of congenital cutis laxa.

    Full Text Available Leukemia cutis (LC is defined as infiltration of the skin by leukemic cells resulting in clinically recognizable cutaneous lesions. It is common in congenital leukemia and acute myeloid leukemia. However, LC has rarely been reported with mixed phenotypic acute leukemia (MPAL. We report the case of a lady who presented with erythematous papular and nodular lesions all over the body. Skin biopsy showed leukemic infiltration and bone marrow aspiration showed MPAL of the T/myeloid with monocytic differentiation lineage. This is the first report of an adult patient with MPAL of the T/myeloid with monocytic differentiation type presenting with leukemia cutis. She was started on chemotherapy with Hyper-CVAD. There is complete resolution of the skin lesions and she has achieved bone marrow remission after the first cycle of chemotherapy.

    Full Text Available We are reporting a rare case of amyloidosis cutis dyschromica in a 41-year-old man. This is a rare form of primary cutaneous amyloidosis characterized by reticulate pigmentation with hypopigmented and hyperpigmented macules, onset in childhood, familial tendency in some, occasional mild itching and deposition of amyloid in the papillary dermis. Our case also had multiple bilaterally symmetrical hyperpigmented keratotic papules abutting the axillary vault resembling those seen in Dowling-Deogs disease. The other unusual feature in this patient was the strong family history of vitiligo, which we are unable to explain. We have also tried to explain the mechanism leading to the hyperpigmentation and hypopigmentation in amyloidosis cutis dyschromica.

    A 4-year-old spayed female mixed breed dog was referred to the Michigan State University, Veterinary Teaching Hospital (MSU-VTH) with vomiting, lethargy and anorexia of 2 weeks duration. Abdominal radiographs and ultrasonography showed hepatosplenomegaly. Cytological evaluation of ultrasound-guided fine needle aspirates of the liver and spleen revealed fungal organisms and pyogranulomatous inflammation; fungal culture documented Paecilomyces variotii infection. The dog received antifungal therapy and supportive care. Multiple firm plaque-like skin lesions, predominantly involving the inguinal region, developed 18 days after initial presentation and were diagnosed histopathologically as calcinosis cutis. While generalized calcinosis cutis has been reported in three dogs with blastomycosis and one dog with leptospirosis, the association with disseminated Paecilomyces spp. infection is novel.

    Hyperelastosis cutis is an inherited autosomal recessive connective tissue disorder. Affected horses are characterized by hyperextensible skin, scarring, and severe lesions along the back. The disorder is caused by a mutation in cyclophilin B. The crystal structures of both wild-type and mutated (Gly6->Arg) horse cyclophilin B are presented. The mutation neither affects the overall fold of the enzyme nor impairs the catalytic site structure. Instead, it locally rearranges the flexible N-terminal end of the polypeptide chain and also makes it more rigid. Interactions of the mutated cyclophilin B with a set of endoplasmic reticulum-resident proteins must be affected.

    2015-11-01

    This study was conducted to evaluate the microbial quality of lamb and goat meat sold through local (Virginia) and Internet (U. S.) retail markets. A total of 134 frozen meat products consisting of locally purchased lamb ground (LLG) and lamb chops and Internet-procured lamb ground, goat ground, lamb chops (ILC), goat chops (IGC), lamb stew, and goat stew were tested. Significantly higher levels of aerobic mesophiles, psychrotrophs, and coliforms were found in the meat locally acquired than in the meat procured from the Internet. Similar average prevalence (27%) of Escherichia coli was observed regardless of market source. Ground meat had significantly high levels and prevalence of mesophiles, psychrotrophs, coliforms, and Listeria spp. One sample of LLG contained Campylobacter, and one sample of IGC contained Salmonella. Listeria spp. were present in 23 to 40% and 17 to 80% of samples from local and Internet markets, respectively. Pulsed-field gel electrophoresis (PFGE) of isolated E. coli strains revealed brand specificity and genomic diversity. No isolate from different brands and market sources had matching PFGE profiles. The average price of Internet meat ($23.4/kg) was about 1.2 times higher than the price of local meat, except for ILC, whose price was 2.7 times higher. This study revealed differences in microbial quality of lamb and goat meat based on market source; thus, meat products should be handled carefully regardless of market source because of the presence of high microbial levels and the high prevalence of pathogens.

    The infection of Arabidopsis thaliana plants with avirulent pathogens causes the accumulation of cGMP with a biphasic profile downstream of nitric oxide signalling. However, plant enzymes that modulate cGMP levels have yet to be identified, so we generated transgenic A. thaliana plants expressing the rat soluble guanylate cyclase (GC) to increase genetically the level of cGMP and to study the function of cGMP in plant defence responses. Once confirmed that cGMP levels were higher in the GC transgenic lines than in wild-type controls, the GC transgenic plants were then challenged with bacterial pathogens and their defence responses were characterized. Although local resistance was similar in the GC transgenic and wild-type lines, differences in the redox state suggested potential cross-talk between cGMP and the glutathione redox system. Furthermore, large-scale transcriptomic and proteomic analysis highlighted the significant modulation of both gene expression and protein abundance at the infection site, inhibiting the establishment of systemic acquired resistance. Our data indicate that cGMP plays a key role in local responses controlling the induction of systemic acquired resistance in plants challenged with avirulent pathogens.

    2011-05-01

    We report three cases of primary osteoma cutis in children, two of whom (siblings) were associated with Albright's hereditary osteodystrophy (AHO), manifesting as short stature with autosomal dominant inheritance from the father, but no dysmorphic features and no parathyroid hormone (PTH) resistance. Osteoma cutis can manifest as an isolated skin disease, a secondary condition to other skin diseases (such as acne), or in association with several syndromes, including AHO, which in turn may be associated with PTH resistance. The management and prognosis of patients diagnosed with osteoma cutis is determined by whether the skin manifestation has occurred in isolation, in association with a syndrome, or as a secondary skin disease. These three paediatric cases highlight the importance of understanding the aetiology and associations of osteoma cutis in order to appropriately investigate and manage patients who present with this rare skin disease.

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

    Full Text Available We herewith report a case of extramedullary myeloid cell tumour presenting as leukaemia cutis for its rarity. It occurred in a 50 year old male patient who presented to us with a 40 days history of painless raised solid skin swellings over the trunk. Histopathological examination of the skin biopsy and bone marrow biopsy showed features suggestive of non-Hodgkin’s lymphoma. Immunophenotyping on skin biopsy specimens and bone marrow biopsy found tumour cells expressing CD43 and Tdt but were negative for CD3 and CD20. These features were consistent with extramedullary myeloid cell tumour involving skin and subcutis (cutaneous manifestation of acute myeloid leukaemia.

    Full Text Available Leishmaniasis recidiva cutis (LRC is an unusual form of acute cutaneous leishmaniasis. Herein, we present a case of LRC of the lips mimicking granulomatous cheilitis. An 8-year-old, Syrian child admitted with a swelling and disfigurement of his lips for 4 years. Abundant intra and extracellular Leishmania amastigotes were determined in the smear prepared from the lesion with Giemsa stain. Histopathology showed foamy histiocytes and leishmania parasites within the cytoplasm of macrophages in the epidermis and a dense dermal mixed type inflammatory cell infiltrate composed of lymphocytes, foamy histiocytes with multinucleated giant cells. On the basis of anamnestic data, the skin smears results, clinical and histopathologic findings, LRC was diagnosed. The patient was treated with meglumine antimoniate intramuscularly and fluconazole orally. Cryotherapy was applied to the residual papular lesions. The lesion improved markedly at the first month of the treatment.

    Sound localization in the horizontal (azimuth) plane relies mainly on interaural time differences (ITDs) and interaural level differences (ILDs). Both are distorted in listeners with acquired unilateral conductive hearing loss (UCHL), reducing their ability to localize sound. Several studies demonstrated that UCHL listeners had some ability to localize sound in azimuth. To test whether listeners with acquired UCHL use strongly perturbed binaural difference cues, we measured localization while they listened with a sound-attenuating earmuff over their impaired ear. We also tested the potential use of monaural pinna-induced spectral-shape cues for localization in azimuth and elevation, by filling the cavities of the pinna of their better-hearing ear with a mould. These conditions were tested while a bone-conduction device (BCD), fitted to all UCHL listeners in order to provide hearing from the impaired side, was turned off. We varied stimulus presentation levels to investigate whether UCHL listeners were using sound level as an azimuth cue. Furthermore, we examined whether horizontal sound-localization abilities improved when listeners used their BCD. Ten control listeners without hearing loss demonstrated a significant decrease in their localization abilities when they listened with a monaural plug and muff. In 4/13 UCHL listeners we observed good horizontal localization of 65 dB SPL broadband noises with their BCD turned off. Localization was strongly impaired when the impaired ear was covered with the muff. The mould in the good ear of listeners with UCHL deteriorated the localization of broadband sounds presented at 45 dB SPL. This demonstrates that they used pinna cues to localize sounds presented at low levels. Our data demonstrate that UCHL listeners have learned to adapt their localization strategies under a wide variety of hearing conditions and that sound-localization abilities improved with their BCD turned on.

    Full Text Available Um caso de Leishmaniose Cutis Difusa é estudado quanto aos seus aspectos imunológicos. A imunidade celular foi investigada com testes intradérmicos, sensibilização artificia! do DNCB e dosagem de fator de inibição do macrófago (MIF. Embora alguns antígenos injetados tivessem dado reação positiva, a leishmanina foi não reatora evidenciando uma anergia específica. As imunoglobulinas G e M estavam elevadas. 0 encontro de anticorpos circulantes por alguns autores associando ao fato de que o complemento C3 era baixo em nosso paciente, levou-nos a considerar o consumo deste que fixado a complexos Ag-Ac circulantes poderiam explicar os surtos de febre e artralgias. Por fim são considerados os pontos de vista de autores diferentes em relação ao fato de que a LCD seria causada por espécie diferente de leishmânia, ou por defeito imunológico do paciente, destacando-se o trabalho de Convit³ em favor desta útlima hipótese.A case of Cutis Diffuse Leishmaniasis is studied in respect to its immuno logical aspects. Cell mediated immunity was investigated with a battery of nine intradermal antigens, using disposable 1.0 ml tuberculin syringes, with 25 guage oedles. Also, artificial sensibilization to the DNCB and dosage of the Macrophage Inhibiting Factor (MIF were carried out. Some of the intradermal tests were positive and the leishmanine reaction was negative showing specific anergy. The G and M immunoglobulines were elevated. Since circulating antibodies have been described in the literatura and our patient had tpe C³ complement at a low level we ponder about its consumption fixed to Ag-Ac complexes, which could explain the episodes of fever and arthralgias. Finally, the view points of different authors are considered in relation to the fact that CDL would be caused by a different species of leishumania, or by immunological defect of the host. Convit's reatons undoubtedly favors th is last hypothesis.

    2015-04-01

    Pseudofolliculitis cutis (PFC) is a troublesome and potentially disfiguring cutaneous disorder characterized by a chronic inflammatory response to ingrown hair. Despite a simple precipitating stimulus, ingrown hair, PFC has a relatively complex aetiology that can involve grooming practices, hair type, genetic predisposition and medication history. Curly hair and a single-nucleotide substitution in the gene encoding keratin 75 may act synergistically to increase the risk for developing this condition. PFC is most common in men of sub-Saharan African lineage, but can occur in men and women of many different ethnicities, particularly in body areas where hair is coarse, abundant and subject to traumatic removal. Treatment options for PFC can be divided into three main categories: modifying hair removal practices, managing symptoms with medication, and long-term hair removal with laser therapy. Laser hair removal is safe and effective in most skin types and has become increasingly popular among dermatologists in the treatment of PFC. However, it is imperative that the laser system and parameters are specifically matched to the patient's skin type.

    Full Text Available Cutis marmorata telangiectatica congenita (CMTC is a rare congenital disorder with persistent cutis marmorata, telengiectasia, and phlebectesia, which may be associated with cutaneaus atrophy and ulceration of the involved skin. We herewith report a full-term newborn female baby with CMTC at birth with ulceration over the extensor aspects of both the knee joints and right elbow joint. CMTC is a benign vascular anomaly representing dilatation of capillaries and veins of dermis and is apparent at birth. The baby had a reticulated bluish purple skin changes all over the body including the face and limb. Although it resembled physiological cutis marmorata, it was strikingly pronounced and definitely was unvarying and permanent. A variety of vascular malformation has been described along with this disorder. Etiology is not very clear and may be multifactorial, teratogens and genes are also been suggested. Prognoses in uncomplicated cases are good.

    Meglumine Antimoniate (MA), administered intramuscularly for 21 continuous days is the recommended treatment of leishmaniases in Ecuador. However, because of its toxicity and requirement for intramuscular injections, treatment is frequently abandoned before completion. In addition, therapeutic failure and reactivation are not uncommon. Here we evaluate the efficacy and safety of MA administered intralesionally (IL) in leishmaniasis recidiva cutis (LRC). LRC is a special clinical variant of cutaneous leishmaniasis, characterized by reactivation at the edges of a primary cured lesion, presenting with active papules around the scar. Twenty-one patients were included in the study. All were diagnosed parasitologically by one of three diagnostic methods (smear, culture, and Leishmanin skin test). Each patient received MA intralesionally weekly for 4 weeks. Each papule was infiltrated until complete saturation. On average, patients received 1 mL of MA per administration. The criterion of cure was the complete resolution of the papules. Follow up was performed at 30, 90, and 180 days after treatment. At day 30 after treatment, 19 (90.5%) of 21 patients were clinically cured. The two patients, who did not heal by the fourth application, were cured on the seventh and eighth dose, achieving a clinical cure of 100% without subsequent reactivation. Mild to moderate local pain during infiltration was the only adverse reaction experienced by 81% of patients. In one case, subsequent infiltrations were discontinued because of a local allergic reaction. Complete compliance of patients to treatment and the small volume of drug administered make this method of administering MA an effective, safe, and inexpensive alternative. Consequently, IL could replace intramuscular administration in the treatment of LRC in Ecuador.

    Mixed micron-sized Cu/Ti3SiC2 (vol5%) powder was mechanically milled using agate balls and zirconia balls separately. Then followed an examination of it with the FEI-SEM. The experimental results show that, distributed homogenously in Cu matrix, the Ti3SiC2 particles have a size of about 30-50 nm after milled with agate balls for 8 h, while it remains approximately unchanged after milled with zirconia balls. The microstructure of the mixture at different ball-milling stages was also studied. Bulks of Cu/Ti3SiC2 nano-composite were fabricated by hot pressing nano-sized Cu/Ti3SiC2 powder at the temperature of 1 073 K under 100 MPa. Then came an investigation of the effects of the particle size and agglomerate state of Ti3SiC2 as well as the microstructure of Cu/Ti3SiC2 nano-composite. It was found that the nano-sized Ti3SiC2 particles distribute evenly in copper.

    Elastic fibers in the extracellular matrix are integral components of dermal connective tissue. The resilience and elasticity required for normal structure and function of the skin are attributable to the network of elastic tissue. Advances in our understanding of elastic tissue physiology provide a foundation for studying the pathogenesis of elastic tissue disorders. Many acquired disorders are nevertheless poorly understood owing to the paucity of reported cases. Several acquired disorders in which loss of dermal elastic tissue produces prominent clinical and histopathologic features have recently been described, including middermal elastolysis, papular elastorrhexis, and pseudoxanthoma-like papillary dermal elastolysis, which must be differentiated from more well-known disorders such as anetoderma, acquired cutis laxa, and acrokeratoelastoidosis. Learning objective At the conclusion of this learning activity, participants should have an understanding of the similarities and differences between acquired disorders of elastic tissue that are characterized by a loss of elastic tissue.

    Full Text Available Background: antimicrobial resistance is recognized as one of the greatest threats to human health worldwide. Infections caused by multidrug-resistant bacteria are associated with higher incidences of mortality, morbidity, prolonged hospital stay and increase of costs. Surveillance of alert organism/conditions and bacterial resistance to antimicrobials is a systematic and dynamic system of data collection that analyses and monitors trends of bacterial resistance. This study was conducted to detect antimicrobial susceptibility patterns in order to inform treatment choices and generate hospital-wide baseline data.Methods: the Local Healtcare Oganization of Rovigo has started a program of surveillance on antimicrobial resistance in hospital and community. In this work some results of the surveillance of microorganism isolated and related antimicrobial resistance are reported, collected in the period 2009-2010 in Rovigo and Trecenta Hospitals, Territorial Nursing Homes (TNH and community from patients’ blood, urine and respiratory samples.Results: data show a significant difference in the level of antibiotic resistance between the two Hospitals. High rates of extended-spectrum β-lactamase (ESBL-producing organisms are detected and carbapenems are the only reliable agents for the treatment of many infections in the Hospital of Trecenta and TNH.Conclusions: because ESBL producing bacteria are emerging pathogens in the community, the rational use of available antibiotics or the appropriate antimicrobial prescribing are imperative. Local surveillance is a powerful tool to detect and monitor hospital and community infections and provides information useful as a guide to medical practice, including therapeutics and disease-control activities.

    Full Text Available Abstract Background Uropathogenic E.coli (UPEC are among major pathogens causing urinary tract infections. Virulence factors are mainly responsible for the severity of these emerging infections. This study was planned to investigate the distribution of virulence genes and cytotoxic effects of UPEC isolates with reference to phylogenetic groups (B2, B1, D and A to understand the presence and impact of virulence factors in the severity of infection in Faisalabad region of Pakistan. Methods In this study phylogenetic analysis, virulence gene identification and cytotoxicity of 59 uropathogenic E.coli isolates obtained from non-hospitalized patients was studied. Results Among 59 isolates, phylogenetic group B2 (50% was most dominant followed by groups A, B1 (19% each and D (12%. Isolates present in group D showed highest presence of virulence genes. The prevalence hlyA (37% was highest followed by sfaDE (27%, papC (24%, cnf1 (20%, eaeA (19% and afaBC3 (14%. Highly hemolytic and highly verotoxic isolates mainly belonged to group D and B2. We also found two isolates with simultaneous presence of three fimbrial adhesin genes present on pap, afa, and sfa operons. This has not been reported before and underlines the dynamic nature of these UPEC isolates. Conclusions It was concluded that in local UPEC isolates from non-hospitalized patients, group B2 was more prevalent. However, group D isolates were most versatile as all were equipped with virulence genes and showed highest level of cytotoxicity.

    Neonatal lupus is a rare disease caused by the transplacental transfer of maternal autoantibodies to the foetus, characterized by transient clinical manifestations such as cutaneous, haematological, and hepatobiliary events or permanent such as congenital heart block. The typical cutaneous manifestations include erythematous, scaly, annular or arched lesions on the face, with slight central atrophy and photosensitivy, clinically and histologically similar to subacute cutaneous lupus. However, in some cases, the lesions may resemble those in cutis marmorata telangiectatica congenita, although this phenomenon is rare and only eight such cases have been reported to date. We report a case of cutaneous neonatal lupus with atypical lesions on the limbs, which had a reddish-purple marbled appearance, resembling the lesions in cutis marmorata telangiectatica congenita.

    Full Text Available Tuberculosis verrucosa cutis (TVC is a form of cutaneous tuberculosis caused by an exogenous inoculation of Mycobacterium tuberculosis in previously infected or sensitized individuals. Tuberculin sensitivity is moderate to high in these patients. In adults tuberculosis verrucosa cutis occurs commonly on the dorsal aspect of fingers and toes but in children it often occurs on gluteal region and lower extremities. A 36-year-old man presented with verrucous lesion on his right foot which was present for 9 years. It was understood from history that he worked as a rancher. On dermatologic examination 3 verrucous hiperkeratotic plaques were present on medial and plantar aspects of the right foot and also on dorsal aspect of the forth toe of the same foot. In serial biopsy specimens which was obtained from the lesions, histopathologic findings compatible with tuberculosis verrucosa cutis was observed. On the chest X-ray and thoracic tomography there were no sign of infection related with tuberculosis and changes secondary to previous tuberculosis on the left lung were observed. After commencing anti tuberculosis therapy regime consisting of isoniazid, rifampicin, morphazinamide and ethambutol obvious healing in the lesions occurred. This rarely reported case in Turkey showed the importance of histopathologic changes observed in serial biopsies in diagnosis of TVC besides history and clinical course of the lesions. It also emphasized the role of response to treatment in confirming the diagnosis.

    Aleukemic leukemia cutis is an extremely rare condition characterized by the infiltration of leukemic cells in skin without blasts in the peripheral blood. Leukemia cutis is considered a grave prognostic sign, thus early diagnosis is important. Leukemia cutis usually occurs in patients with myeloid leukemia. To the best of our knowledge, there has been no report regarding the radiological findings of aleukemic leukemia cutis, which is probably due to the presence of the skin changes in most patients. We report the ultrasound and MR findings of aleukemic leukemia cutis, even without the skin manifestation in patients with a history of complete remission of the acute lymphoblastic leukemia following an allogeneic peripheral blood stem cell transplantation

    Development of acquired resistance limits the utility of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKI) for the treatment of EGFR-mutant lung cancers. There are no accepted targeted therapies for use after acquired resistance develops. Metastasectomy is used in other cancers to manage oligometastatic disease. We hypothesized that local therapy is associated with improved outcomes in patients with EGFR-mutant lung cancers with acquired resistance to EGFR TKI. Patients who received non-central nervous system local therapy were identified by a review of data from a prospective biopsy protocol for patients with EGFR-mutant lung cancers with acquired resistance to EGFR TKI therapy and other institutional biospecimen registry protocols. Eighteen patients were identified, who received elective local therapy (surgical resection, radiofrequency ablation, or radiation). Local therapy was well tolerated, with 85% of patients restarting TKI therapy within 1 month of local therapy. The median time to progression after local therapy was 10 months (95% confidence interval [CI]: 2-27 months). The median time until a subsequent change in systemic therapy was 22 months (95% CI: 6-30 months). The median overall survival from local therapy was 41 months (95% CI: 26-not reached). EGFR-mutant lung cancers with acquired resistance to EGFR TKI therapy are amenable to local therapy to treat oligometastatic disease when used in conjunction with continued EGFR inhibition. Local therapy followed by continued treatment with an EGFR TKI is well tolerated and associated with long PFS and OS. Further study in selected individuals in the context of other systemic options is required.

    To study characteristics of patients with community-acquired complicated urinary tract infections (cUTIs) and to compare effectiveness and antibiotic cost of treatment with ceftriaxone (CRO), levofloxacin (LVX), and ertapenem (ETP). This retrospective study enrolled patients who had community-acquired cUTIs admitted to Division of Infectious Diseases in a single medical center from January 2011 to March 2013. Effectiveness, antibiotic cost, and clinical characteristics were compared among patients treated with CRO, LVX, and ETP. There were 358 eligible cases, including 139 who received CRO, 128 treated with ETP, and 91 with LVX. The most common pathogen was Escherichia coli. The susceptibilities of these three agents were higher and more superior than first-line antibiotics. Treatment with ETP was associated with a significantly shorter time to defervescence since admission (CRO: 39 hours, ETP: 30 hours, and LVX: 38 h; p = 0.031) and shorter hospitalization stay (CRO: 4 days, ETP: 3 days, and LVX: 4 days; p < 0.001). However, the average antibiotic costs in the CRO group were significantly lower than that in the other two groups [CRO: 62.4 United States dollars (USD), ETP: 185.33 USD, and LVX: 204.85 USD; p < 0.001]. The resistance of cUTIs isolates to first-line antibiotic is high. Using ETP, CRO, and LVX in the treatment of cUTIs for good clinical response should be suggested. Among the three agents, ETP had better susceptibility than CRO and LVX, reached defervescence sooner, and was associated with shorter hospital stays. However, using CRO in cUTIs was less expensive than the other two agents. Copyright © 2015. Published by Elsevier B.V.

    Full Text Available Acquired methemoglobinaemia is a relatively rare condition and, therefore infrequently encountered in acute medical practice. Suspicion of the condition may be triggered when the measured PaO2 is ‘out of keeping’ with the oxygen saturations that are discovered with pulse oximetry. We describe two separate cases of acquired methemoglobinaemia secondary to the recreational use of alkyl nitrites (’poppers’. The patients presented at separate times to two different teaching hospitals in London, UK. The similarity of these cases has led the authors to conclude that a raised awareness of this potentially fatal condition, and its association with a widely-available recreational drug, is necessary to ensure a correct and timely diagnosis.

    Solid state amorphization reactions in Cu-Ti have been studied by means of DSC and structural techniques. The influence of hydrogen from the parent titanium powder on the amorphization and crystallization processes has been investigated. For Cu-Ti a diffusion-controlled process can be inferred for solid state amorphization from the parabolic trend of the heat of crystallization, as a function of the milling time. The presence of hydrogen in the alloys is found to modify the crystallization behaviour of the amorphous phase. A DSC method for the determination of the amount of hydrogen present in the alloys is given. (orig.).

    Comentários: A aplasia cutis congénita é uma lesão que pode ser causadora de grande ansiedade parental, pelo que é importante ao Pediatra o seu reconhecimento e devido esclarecimento. Apesar de se tratar, na maioria das vezes, de um defeito benigno, é importante o conhecimento da sua relação com outras anomalias e síndromes de forma a otimizar a sua orientação precoce e adequada. Da mesma forma, é importante o aconselhamento genético, nos casos que assim o justifiquem.

    In order to unclose the dynamics of SPS densification, a special sintering sample (Cu/Ti wires compact) was designed. Characters of the shrinkage rates during sintering process and microstructures of products fabricated by the spark plasma sintering(SPS) and hot-press sintering were investigated. The experimental results reveal that a higher temperature field is formed at the connected area and conductive net of the compact. These high-temperature parts deformed more easily than other parts, which is believed to be the main cause of SPS fast densification, according to a hard-core and soft-hell material model.

    In this paper, we prepared the binary Cu-Ti nanoglass films by composite deposition technique. The X-ray diffraction and atomic force microscopy indicate that as-synthesized films are consisted of nanoglass with apparent interfaces. The room temperature creep behavior and strain rate sensitivity of as-synthesized nanoglass films were investigated with nanoindetation and explored that Cu58Ti42 has a better creep-resistance property at room temperature but Cu42Ti58 has a more relaxed structure. The as-synthesized nanoglass films exhibit anomalously negative strain rate sensitivity.

    Full Text Available Familial atrophia maculosa varioliformis cutis is a very rare disorder with less than 28 cases being reported in the literature worldwide and remains a mystery both as far as genetics and the virtue of its pathogenesis is concerned. We present a case of mother and son, both having this disorder with presentations unique in terms of sites involved and try to draw a five generations pedigree chart for the same. We further support its inheritance pattern as autosomal dominant. Also, we propose oral isotretinoin as an effective treatment modality for the same.

  8. The effect of NMDA-R antagonism on simultaneously acquired local field potentials and tissue oxygen levels in the brains of freely-moving rats.

    Non-competitive NMDA receptor antagonists are known to induce psychosis-like symptoms in rodents. Administration of such compounds cause behavioural effects such as memory impairment and hyperlocomotion. Additionally, drugs such as phencyclidine (PCP), ketamine and MK-801 all cause distinctive increases in striatal local field potential (LFP) in the high frequency oscillation (HFO) band in the power spectrum (140-180 Hz). Amperometric sensors provide a means to measure tissue oxygen (tO2; a BOLD-like signal) in the brains of freely-moving rats while simultaneously acquiring LFP using the same electrode. Carbon paste electrodes were implanted into the striatum and hippocampus of male Wistar rats. Rats were administered with saline, ketamine (10 mg/kg), MK-801 (0.1 mg/kg) and PCP (2.5 mg/kg) and recordings were made at 1 kHz using three different potentials (-650 mV to measure tO2; 0 mV and +700 mV as control conditions). NMDA receptor antagonism caused significant increases in tO2 in both the striatum and the hippocampus. Power spectrum analysis showed significant increases in HFO power in the striatum but not in the hippocampus. Conversely, there were significant decreases in delta and alpha power along with increases in theta and gamma power in the hippocampus that were absent in the striatum. This supports findings that LFP can be obtained from an amperometric sensor signal; allowing simultaneous acquisition of two translational biomarkers of neuronal activity (LFP and tO2).

  9. The role of diclofenack on inducing of aplasia cutis congenita: a case report

    2009-01-01

    Background Aplasia cutis congenita is a disorder where e newborn child is missing skin from certain areas. It is a rare condition with no particular race or sex more at risk. May occur by itself or be associated with other physical syndromes or disorders. A classification system exists for aplasia cutis congenital consisting of 9 groups, based on the number and location of the skin defects and the presence or absence of other malformations. Causes of aplasia congenital could be heredity, teratogenic substances, placental infarcts, intrauterine infections, ectodermal dysplasias etc. Diagnosis is made based on the clinical findings. Prognosis depends of the other organs malfunction level and lesions size. Case report Our case was an 22 months old Albanian girl, who was recommended to dermatology for a consultation by a pediatric surgeon because of the changes she had on her parietal part of the scalp with missing hair areas. The child has stenosis congenita ani and to her was installed stoma. In order to investigate other accompanied anomalies of the disease, there are made specific consults by neurologist, orthopedist, cardiologist, nephrologists and citogenetics. Conclusion It was found out a minor visual discoordination, Sy Floppy, Digiti V superductus pedis bill. Laxitas articularum generalisata. It was a great challenge for us to find out that during the first trimester of the pregnancy (unplanned pregnancy), her mother used Diclofenac. Since there is limited information regarding to teratogenic effects of diclofenac, we considered it interesting to present this case. PMID:19946521

    2010-01-01

    In order to investigate the high temperature exposure effect on Nb-Ti/Cu superconducting strands, as might be encountered in joining by soldering and in cabling annealing, X-ray diffraction and resistometry measurements were performed in situ during heat treatment, and complemented by conventional metallography, mechanical tests and superconducting properties measurements. Changes of the Nb-Ti nanostructure at temperatures above 300 degrees C are manifested in the degradation of critical current in an applied external magnetic field, although degradation at self field was insignificant up to 400 degrees C for several minutes. Above 500 degrees C, the formation of various Cu-Ti intermetallic compounds, due to Ti diffusion from Nb-Ti into Cu, is detected by in situ XRD albeit not resolvable by SEM-EDS. There is a ductile to brittle transition near 600 degrees C, and liquid formation is observed below 900 degrees C. The formation of Cu-Ti causes a delayed reduction of the residual resistivity ratio (RRR) and adv...

    2016-01-01

    Cutaneous lymphoid hyperplasia (CLH) is a cutaneous pseudolymphoma with a worldwide distribution, equally affecting all races and ethnic groups. Due to its vast array of characteristics, it is most often missed in the differential diagnosis of firm to soft lumps on the head and neck. A systematic approach to the workup and diagnosis along with treatment of such lesions is discussed in this article. A 20-year-old Asian Indian female presented to our Oral and Maxillofacial unit with a lump on the left side of her forehead for 1 month. Local examination revealed a 2.5×3.0 cm2, well circumscribed swelling over the left para median region that was firm to doughy and non-tender. There was no other significant finding on general examination. Excisional biopsy of the lesion was performed, followed by histopathologic processing. The general etiology, pathogenesis, clinical presentation, differential diagnosis, clinical course, prognosis, treatment, and prevention have been discussed in line with the recent modalities of diagnosis and treatment of CLH. Due to the overlapping clinical and histological characteristics of CLH with many other lesions, it is important to consider this lesion in the differential diagnosis of cutaneous lesions.

    Fibroblast cultures were established from six patients with cutis laxa, and elastin gene expression was analyzed by RNA hybridizations with a 2.5-kilobase human elastin cDNA or an exon 1-specific 35-base oligomer. Northern analyses using either probe detected mRNA transcripts of approx. 3.5 kilobases, and no qualitative difference between the control and cutis laxa mRNAs was detected. However, quantitation of the elastin mRNA abundance by slot blot hybridizations revealed markedly reduced levels in all cutis laxa cell strains. Assuming equal translational activity of the control and cutix laxa mRNAs, the reduced mRNA levels could result in diminished elastin production, providing an explanation for the paucity of elastic fibers in the skin and other tissues in cutis laxa.

    Cu/Ti films of various Cu/Ti ratios were prepared on a TiNi alloy via vacuum arc plasma deposition. The phase composition, structure, and concentration of elements were investigated via X-ray diffraction and X-photoelectron energy spectrum. The hemolysis ratio and platelet adhesion of the different films were characterized to evaluate blood compatibility. The corrosion and ion release behavior were investigated via a typical immersion test and electrochemical method. The growth of endothelial cells (ECs) was investigated, and methylthiazolyte-trazolium method was employed to evaluate the effect of Cu2+. The sophisticated films showed good compatibility. However, with increasing quality ratio of Cu/Ti, the hemolysis ratio increased, and some platelets started to break slightly. The Cu2+ release was gradually stabilized. The open circuit potential of the Cu/Ti film-modified samples was lower than that of the TiNi substrate. The polarization test result indicates that the passivation stability performance of Cu/Ti film samples is less than the TiNi substrate, and is favorable to Cu2+ release. The adhesion and proliferation of ECs would be inhibited with 10 wt.% Cu concentration of the film, and ECs would undergo apoptosis at >50 wt.% concentration. A Cu/Ti film with good compatibility and anti-endothelialization has potential applications for special cardiovascular devices.

    Aplasia cutis congenita (ACC) can be associated with fetus papyraceus. We report here the first case of ACC linked to fetus papyraceus with pulmonary anomalies. At birth, the patient presented with skin lesions of the trunk consisting of well-defined, symmetrically distributed, bilateral atrophic ulcerations. Physical examination was otherwise normal. Persistent bronchospasm occurred at the age of 7 months; computed tomography images showed small bilateral pulmonary bullae. At the age of 5 years, skin and pulmonary lesions had not extended. Although the mechanisms of ACC linked to fetus papyraceus are unclear, vascular ischemia is strongly suggested, and could explain the bilateral and symmetric congenital skin and lung aplasia. © 2013 Wiley Periodicals, Inc.

    Localised agenesis of the scalp is the most frequent pattern in aplasia cutis congenita (ACC), a congenital absence of the skin and occasionally of deeper layers. Several clinical groups are characterised by the location and pattern of skin defects, associated malformations and the mode of inheritance. Death occurs in 20% of cases, secondary to the associated anomalies, to infections or to haemorrhage from ulceration of the sagittal sinus when there is also a defect of the underlying skull. In this latter case, we close the defect by two rotational scalp flaps (Orticochea technique) at birth. A three-dimensional CT study is useful for showing the extent of the skull defect and the deformity of the craniofacial complex and the changes in the bone after treatment.

    An 88-year-old woman with CREST syndrome (calcinosis, Raynaud's phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasias) presented with hyperglycemia, intravascular depletion, and atrial fibrillation. The patient was found to have unusually severe calcinosis cutis in both legs extending from the knees to the ankles bilaterally, as well as Raynaud's phenomenon, sclerodactyly, and telangiectasias. The patient was normocalcemic and normophosphatemic. Although subcutaneous calcification is often seen with CREST syndrome, this case is unusual in that the area of involvement was much larger than previously described. Furthermore, the amount of calcinosis was disproportionately severe and was the major cause of symptoms and disability compared with the other components of the syndrome. (orig.)

    Full Text Available We describe a case of generalized cutis laxa (CL in a 7-year-old female child. At 2 months of age, she was found to have a hoarse voice, and at 3 years, she was much smaller than her peers. Her aging face and short stature caught our attention, and the treatment of the patient was accepted by our hospital. She underwent a thorough examination. X-ray of the wrist bone showed a markedly delayed bone age, and thyroid function tests revealed significantly elevated free triiodothyronine 3 and free thyroxine 4 levels, but thyrotropin was within the normal range. Thyroid dysfunction and CL can be associated with lagged growth and development. Whether her abnormal development was due to thyroid dysfunction or CL could not be ascertained. CL is possibly more complex than it has been supposed so far, and is therefore worth to be further studied.

    Full Text Available Hypercalcemia in children with malignancy is an uncommon condition. It has been described in leukemia patients with impaired renal excretion of calcium or osteolytic lesions. Metastatic calcinosis cutis (MCC may develop if hypercalcemia persists. We report the case of a 5-year-old girl with an atypical dermatosis and unspecific gastrointestinal symptoms. Considered clinical diagnoses were xanthomas, histiocytosis, molluscum contagiosum, and nongenital warts. Cutaneous histological analysis showed amorphous basophilic deposits in the dermis suggestive of calcium deposits. Laboratory tests confirmed serum hypercalcemia. Extensive investigations such as bone marrow biopsy established the diagnosis of an acute pre-B cell lymphoblastic leukemia. Hypercalcemia in hematopoietic malignancies is unusual, especially as initial manifestation of the disease. Careful review of the literature fails to reveal previous reports of these peculiar cutaneous lesions of MCC in children with leukemia.

    Full Text Available Neonatal lupus is a rare disease caused by the transplacental transfer of maternal autoantibodies to the foetus, characterized by transient clinical manifestations such as cutaneous, haematological, and hepatobiliary events or permanent such as congenital heart block. The typical cutaneous manifestations include erythematous, scaly, annular or arched lesions on the face, with slight central atrophy and photosensitivy, clinically and histologically similar to subacute cutaneous lupus. However, in some cases, the lesions may resemble those in cutis marmorata telangiectatica congenita, although this phenomenon is rare and only eight such cases have been reported to date. We report a case of cutaneous neonatal lupus with atypical lesions on the limbs, which had a reddish-purple marbled appearance, resembling the lesions in cutis marmorata telangiectatica congenita.Lúpus neonatal é uma doença rara causada pela transferência de auto-anticorpos maternos para o feto, caracterizada por manifestações clínicas transitórias como cutâneas, hematológicas e hepatobiliares, ou permanentes como o bloqueio cardíaco congênito. As manifestações cutâneas típicas incluem lesões fotossensíveis descamativas, anulares ou arqueadas na face, com discreta atrofia central, clinica e histopatologicamente similares ao lúpus cutâneo subagudo. Entretanto, em alguns casos, as lesões podem lembrar aquelas da cutis marmorata telangiectatica congênita, mas esse fenômeno é raro e somente oito casos foram reportados até hoje. Nós relatamos aqui um caso de lúpus cutâneo neonatal com lesões atípicas nos membros de cor vermelho-purpúricas e aparência marmórea, semelhantes às lesões da cutis marmorata telangiectatica congênita.

    Full Text Available Objective: This study aimed to determine the etiologic factors of acquired methemoglobinemia in infants younger than three months in our region. Material and Methods: This study was carried out retrospectively in infants with methemoglobinemia admitted to Karadeniz Technical University, Pediatric Clinic, during the period 2000-2009. Infants with methemoglobinemia were identified according to the medical records or ICD-10 code. Results: Nine infants with acquired methemoglobinemia (8 male, 1 female were included in the study. Seven cases were associated with the use of prilocaine for circumcision, one case with the use of prilocaine-lidocaine for local pain therapy, and one case with neonatal sepsis caused by Staphylococcus aureus.Conclusion: Prilocaine should not be used in infants less than three months of age because of the risk of methemoglobinemia. Ascorbic acid is an effective therapy if methylene blue is not obtained. It should not be forgotten that sepsis caused by S. aureus may cause methemoglobinemia in infants.

    Elastic fibres are critical connective tissue components providing elasticity and resilience to skin and other tissues. These fibres are composed of elastin and a number of elastin-associated microfibrillar proteins that assemble in a complex fibre network in a multi-step process. Multiple cellular processes, including mitochondrial function, specific molecules in the secretory pathways and temporally and spatially ordered production of elastic fibre components, are required for the biogenesis of functional elastic fibres. Abnormalities in these processes can lead to loss of functional elastic fibres manifesting phenotypically as a skin disease. The paradigm of elastic fibre diseases affecting the skin is cutis laxa, a clinically and genetically heterogeneous group of disorders characterized by loose and sagging skin, frequently associated with extracutaneous manifestations in the lungs and the arterial blood vessels. The complexity of cutis laxa is emphasized by the fact that as many as 10 distinct genes can harbour mutations in this and related disorders. Understanding of the pathomechanistic pathways involved in perturbed elastic fibre assembly in cutis laxa provides information potentially helpful for the development of molecular strategies towards treatment of these, currently intractable, diseases.

    The aim of our study was to explore the possibility of detecting hemodynamic changes in the brain using the phase of the intensity modulated optical signal. To obtain optical signals with the highest possible signal-to-noise ratio, we performed a series of simultaneous NIRS-fMRI measurements, with subsequent correlation of the time courses of both measurements. The cognitive paradigm used arithmetic calculations, with optical signals acquired with sensors placed on the forehead. Measurements were done on seven healthy subjects. In five subjects we demonstrated correlation between the hemodynamic signals obtained using NIRS and BOLD fMRI. In four subjects correlation was found for the hemodynamic signal obtained using the phase of the intensity modulated signal.

    In the present paper, we are going to report on a detailed study of the characteristics of an electrochemical oxygen pump for an open system using Cu-Ti double substituted bismuth vanadate as the electrolyte. The major objectives are to show a correlation between oxygen pumping current, cell voltage, Faradic efficiency and oxygen production rate. The maximum current density that can be applied without significant structural modification has been determined and the effect of working temperature on the mentioned parameters have been investigated. The results show that there is an Ohmic relationship between current and voltage at low current densities and a deviation towards lower voltages than expected from Ohm's law with increasing current density. The oxygen production rate increased in a linear fashion by increasing the current density while at high current densities, corresponding to the non linear current voltage section, its gradient decline. Under constant current load, at very high current density (I > 800 mAcm{sup -2}), instability in cell potential was observed, which was reversible and supposed to be the effect of electronic percolation.

    Full Text Available The aim of the this work was to determine the finger patterns, Finger Ridge Count (FRC, Total Finger Ridge Count (TFRC, and Asymmetry of Finger Ridge Count (AFRC of an Iranian girl (aged 13 years affected with congenital cutis laxa (CCL.The fingerprints of the first phalanx of both hands were taken by using the standard method (stamp ink. The fingerprints were classified according to the Galton nomenclature. The patterns of palm creases were also studied. Besides, the ridges of fingerprints of all ten fingers were counted, then employing the related formulas, the FRC, TFRC and AFRC were calculated.Results showed that the finger patterns of all ten fingers were radial loop; the major creases of the palms existed but their sizes were not normal. TFRC, which is the sum of all ten FRCs, was 77 (“low”, and AFRC was 10.344, more than that of her normal sister, that was 7.280. It is concluded that in CCL, the TFRC and symmetry of the fingertips ridges count may decrease; also palm pattern may be unusual.

    Full Text Available Background: Pachyderma is defined as severely thickened skin with deep folds and is occasionally observed with primary cutaneous NK and T-cell lymphoma (pCNKTCL, primary cutaneous B-cell lymphoma (pCBCL, and leukemia cutis (LC. Aim: To describe the clinical, histological, and therapeutic particularities of a series of pCNKTCL, pCBCL, and LC patients with pachyderma. Results: In a series of pCNKTCL (n = 70, pCBCL (n = 12, and LC (n = 2 patients followed up during 9 years, 6 cases of pachyderma were observed. Pachyderma occurred on the arms (n = 2, thighs (n = 1, forehead (n = 1, and face (n = 2. The mean age of the patients was 69 years (51–82. The stages were erythrodermic (T4 mycosis fungoides (MF (n = 1, folliculotropic MF (FMF (n = 2, classic (T2 MF (n = 2, and chronic myeloid leukemia (n = 1. The erythrodermic MF patient with acute pachyderma on the right arm responded rapidly to oral steroids. The other cases were indolent, appeared progressively, and were highly treatment resistant. Histology revealed dense dermal neoplastic infiltration. The immunohistological profile of the pachydermic lesions was similar to common MF and LC. Conclusion: Pachyderma is an atypical manifestation of MF and LC and may occur on the face (FMF or the extremities (MF. The rapidly appearing pachyderma may be transitory and responds readily to oral steroids.

    2014-01-01

    Full Text Available Tuberculosis verrucosa cutis (TVC, also known as warty tuberculosis, anatomist's wart or prosector's wart is characterized by the presence of verrucous plaque-like lesions, resulting from direct inoculation of the causative organism into the skin of a previously infected patient. A 59-year-old man presented with a hyperpigmented plaque on the chest wall which closely mimicked a keloid. He was a case of sputum-positive pulmonary tuberculosis and had repeatedly been applying early morning saliva on the lesion as a part of the indigenous practices for quick healing. There was further progression of the lesion with discharge from several sites. A smear for acid fast bacilli was positive from the discharge and growth on Lowenstein Jensen medium revealed growth of Mycobacterium tuberculosis. Biopsy was compatible with TVC and the patient was started on 6 months anti-tubercular therapy. However, the plaque continued to persist with continuing discharge from multiple openings which necessitated surgical intervention, finally leading to near complete resolution of the plaque of TVC.

    Full Text Available Two unrelated patients of different sexes are described, both presenting with congenital redundant skin (cutis laxa, growth deficiency, mental retardation and bone dystrophy. Parental consanguinity in both families and a more pronounced severity of the neurological disease in the male patient were present. Both patients were diagnosed in infancy as having De Barsy syndrome, but clinical follow-up revealed that the clinical picture was compatible with the diagnosis of cutis laxa with growth and developmental delay (CLGDD, gerodermia osteodysplastica (GO and wrinkly-skin syndrome (WWS. It has recently been suggested that cutis laxa with growth and developmental delay, gerodermia osteodysplastica and wrinkly skin syndrome are the same condition. A review concerning this diagnosis is also presented.

    Full Text Available The process of socio-educational territorialisation in rural contexts is the topic of this text. The theme corresponds to a challenge to address it having as main axis of discussion either the problem of social exclusion or that of local development. The reasons to locate the discussion in this last field of analysis are discussed in the first part of the text. Theoretical and political reasons are there articulated because the question is about projects whose intentions and practices call for the political both in the theoretical debate and in the choices that anticipate intervention. From research conducted for several years, I use contributions that aim at discuss and enlighten how school can be a potential locus of local development. Its identification and recognition as local institution (either because of those that work and live in it or because of those that act in the surrounding context are crucial steps to progressively constitute school as a partner for development. The promotion of the local values and roots, the reconstruction of socio-personal and local identities, the production of sociabilities and the equation and solution of shared problems were the dimensions of a socio-educative intervention, markedly globalising. This scenario, as it is argued, was also, intentionally, one of transformation and of deliberate change of school and of the administration of the educative territoires.

    Menkes disease is an X-linked disorder of copper metabolism. The complex clinical phenotype is attribute to a deficiency of copper-containing enzymes resulting from a defect in copper transport. X-linked cutis laxa (XLCL), a mild, connective tissues disease may also be an allele of Menkes disease. A gene for the Menkes disease locus (MNK) has been isolated and found to code for a copper-transportion ATPase. Deletions in this gene have been observed in only 15-20% of patients by Southern blot analysis. We have analysed the MNK gene for mutations by RT-PCR and chemical cleavage mismatch detection in a group of 12 patients with severe Menkes phenotype and who were normal by Southern analysis. Mutations were observed in ten patients, and in each case, a different, debilitating mutation was present. Mutations that resulted in splicing abnormalities, detected by RT-PCR alone, were observed in six patients and included two splice site changes, a nonsense mutation, a missense mutation, a small duplication and a small deletion. Chemical cleavage analysis of the remaining six patients revealed the presence of one nonsense mutation, two adjacent 5 bp deletions and one missense mutation. A valine/leucine polymorphism was also observed. These findings, combined with the prior observation of large deletions in {approx}15% of patients, suggest that Southern blot hybridization and RT-PCR will identify mutations in the majority of patients. To date, no mutations have been found in 4 XLCL patients in the MNK coding region by chemical cleavage. However in 2 patients Southern blot changes have been detected with a 5{prime} UTR probe, suggesting mutations affecting regulatory elements.

    We report a 7.5-year-old boy with loose translucent skin, aortic dilatation, hyperextensible veins, recurrent respiratory problems, pectus excavatum, arthralgias, lax joints, mild epiphyseal dysplasia, and umbilical and inguinal hernias. He also has developmental delay, progressive bilateral sensorineural hearing loss, an unusual facial appearance, terminal digit hypoplasia with unusual radiographic changes in some of the phalanges, glandular hypospadias, shawl scrotum, and undescended testes. Biochemical investigations, including electrophoresis of Types 1 and 3 procollagens and collagens, and quantification of serum copper and ceruloplasmin, are normal. Relative to age-matched control patients the electron micrographs of the boy's dermis show elastin fibers to be decreased in number, and abnormal in appearance, with a low matrix to microfibril ratio. The organ distribution of abnormalities and the nature of the findings suggest a connective tissue disorder. We contrast and compare this boy's phenotype to those of the classic connective tissue disorders. We conclude that he has cutis laxa with features that distinguish him from previously described types of cutis laxa.

    The phase relationships of the Cu-Ti-Er ternary phase diagram at 773 K (500 °C) were investigated mainly by means of X-ray powder diffraction (XRD), scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS), and differential thermal analysis (DTA). It is confirmed in this work that the binary compounds Cu9Er2 and Cu7Er2 exist in the Cu-Er binary system at 773 K (500 °C). The stability of the CuTi3 phase is confirmed in the Cu-Ti system. After heat treatment at 1023 K (750 °C) for 90 hours, the phase CuTi3 is observed in the microstructure of the alloy 25Cu75Ti. The temperature of the eutectoid transformation, namely, β-Ti ↔ α-Ti + CuTi3, is determined to be 1078 K (805 °C) in this work. The 773 K (500 °C) isothermal section consists of 14 single-phase regions, 25 two-phase regions, and 12 three-phase regions. None of the phases in this system reveals a remarkable homogeneity range at 773 K (500 °C).

    Full Text Available Cutis verticis gyrata is a rare skin condition characterized by swelling of scalp resembling the surface of the brain. Various conditions, like cerebriform intradermal nevus (CIN, may give rise to this clinical entity. Moreover, its association with cellular blue nevus is extremely rare and has not been reported so far. Here, we report a 28-year-old male with a huge cerebriform swelling covering the occipital lobe along with multiple nodules all over the body. Histology of the scalp swelling showed solitary or clusters of nevus cells in the dermis and from the body lesions showed features of cellular blue nevus. The diagnosis of CIN with cellular blue nevus was confirmed

    The acquired demyelinating neuropathies can be divided into those with an acute onset and course and those with a more chronic course. The acute neuropathies present as Guillain-Barré syndrome and include acute inflammatory demyelinating polyradiculoneuropathy (AIDP), Miller Fisher syndrome, acute motor axonal neuropathy (AMAN), acute motor and sensory axonal neuropathy (AMSAN), and acute pandysautonomia. The chronic neuropathies are collectively known as chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and include MADSAM (multifocal acquired demyelinating sensory and motor neuropathy, also know as Lewis-Sumner syndrome) and DADS (distal acquired demyelinating symmetric neuropathy) as variants. The clinical features, pathology, pathogenesis, diagnosis, treatment, rehabilitation, and prognosis of these neuropathies are discussed.

    Acquired color vision deficiency occurs as the result of ocular, neurologic, or systemic disease. A wide array of conditions may affect color vision, ranging from diseases of the ocular media through to pathology of the visual cortex. Traditionally, acquired color vision deficiency is considered a separate entity from congenital color vision deficiency, although emerging clinical and molecular genetic data would suggest a degree of overlap. We review the pathophysiology of acquired color vision deficiency, the data on its prevalence, theories for the preponderance of acquired S-mechanism (or tritan) deficiency, and discuss tests of color vision. We also briefly review the types of color vision deficiencies encountered in ocular disease, with an emphasis placed on larger or more detailed clinical investigations.

    Full Text Available Neonatal acute megakaryoblastic leukemia (AMKL without Down syndrome (DS is an extremely rare disorder. We report of a one-day-old male infant without DS who developed AMKL with leukemia cutis and right facial nerve palsy. Magnetic resonance imaging of the patient’s brain revealed multiple intracranial tumors. A biopsy specimen of the skin lesion was suggestive of AMKL, but the bone marrow leukemic cells were less than 5% of the marrow nucleated cells. The skin and intracranial lesions had spontaneously regressed within one and a half months, but the patient’s anemia and thrombocytopenia gradually worsened and the leukemic cells in the bone marrow gradually increased to more than 20% of the nucleated cells. In addition, multiple intracranial lesions reappeared at 72 days of life. We diagnosed the patient with AMKL, and chemotherapy followed by unrelated cord blood transplantation after a reduced-intensity conditioning regimen resulted in sustained complete remission. At present, the patient is well, and he has demonstrated normal development for five years.

  13. Modeling autosomal recessive cutis laxa type 1C in mice reveals distinct functions for Ltbp-4 isoforms

    Full Text Available Recent studies have revealed an important role for LTBP-4 in elastogenesis. Its mutational inactivation in humans causes autosomal recessive cutis laxa type 1C (ARCL1C, which is a severe disorder caused by defects of the elastic fiber network. Although the human gene involved in ARCL1C has been discovered based on similar elastic fiber abnormalities exhibited by mice lacking the short Ltbp-4 isoform (Ltbp4S−/−, the murine phenotype does not replicate ARCL1C. We therefore inactivated both Ltbp-4 isoforms in the mouse germline to model ARCL1C. Comparative analysis of Ltbp4S−/− and Ltbp4-null (Ltbp4−/− mice identified Ltbp-4L as an important factor for elastogenesis and postnatal survival, and showed that it has distinct tissue expression patterns and specific molecular functions. We identified fibulin-4 as a previously unknown interaction partner of both Ltbp-4 isoforms and demonstrated that at least Ltbp-4L expression is essential for incorporation of fibulin-4 into the extracellular matrix (ECM. Overall, our results contribute to the current understanding of elastogenesis and provide an animal model of ARCL1C.

    Sterno-costo-clavicular hyperostosis (SCCH) is the most common manifestation of a syndrome, consisting of increased bone metabolism, mostly new bone formation and heterotopic ossification of fibrous tissue, which we have characterised as the acquired hyperostosis syndrome. In part I we discuss the terminology, radiological appearances, scintigraphy, clinical and laboratory findings, bacteriology, histology, nosology, complications, treatment and differential diagnosis of SCCH. Chronic recurrent multifocal osteomyelitis (CRMO) is regarded as a phaenotype of SCCH, depending on the age. CRMO occurs in children, adolescents and young adults, SCCH predominantly in middleaged and elderly adults.

  2. A rare presentation of aplasia cutis congenita after feto-reduction in a trichorionic-triamniotic pregnancy.

    Vettori, D J; Jairath, P

    2015-01-01

    Aplasia cutis congenita (ACC) is rare skin disorder of newborns that has been linked to both assisted reproductive technology (ART) and feto-reduction procedures. ACC is characterized by well-demarcated lesions that are devoid of all skin layers. Group-V ACC presents with a distinctive and symmetrical distribution pattern. It is thought to result from an insult to the fetus after concomitant twin demise and is almost exclusively reported in monochorionic gestations.A 41-year-old female with an in vitro fertilization (IVF) assisted tri-chorionic gestation subsequently underwent selective feto-reduction of Fetus C. The patient delivered two pre-term neonates secondary to pre-eclampsia. The initial exam of Twin B showed extensive, well-demarcated, symmetrical areas devoid of any skin over the anterior and lateral trunk, extending up the lateral thoracic walls. Chest and abdominal viscera were visible through a thin fibrous membrane. The skin defects were managed conservatively with twice-daily dressings of Aquaphor, and Vaseline gauze. The areas of aplasia slowly contracted, though residual scarring was noted. After four weeks in the NICU, most of the areas were healed.ACC in multi-fetal pregnancies is a rare, but well-described complication. This is, to our knowledge, the first reported case in a tri-chorionic IVF gestation after feto-reduction. With increased incidence of ART-associated pregnancies and the use of feto-reduction for higher order gestations, this may become more common. Neonates often require specialized intensive care. Conservative management usually will suffice, although surgical grafting may be required. Physicians should be aware of this condition and counsel their feto-reduction patients of the risk.

    A mesoporous, highly crystalline Cu-Ti composite oxide catalyst was prepared via facile, simple and modified solution method varying Cu and Ti ratio for selective liquid phase oxidation of vanillyl alcohol. Various spectroscopic procedures were employed to systematically characterize the catalyst structural and physicochemical properties. The defect chemistry of the catalyst was confirmed from the presence of surface defects revealed through HRTEM imagery between the TiO2 (101) and Cu3TiO4 (012) planes, complemented by the XRD profiling. Further, presence of oxygen vacancy evidenced by O 1s XPS spectra were observed on the catalyst surface. Moreover, the stoichiometry of Cu and Ti in the catalyst synthesis protocol was notably found to be the vital determinant to alter the redox properties of Cu-Ti composite oxide catalyst supported by H2-TPR. O2-TPD analysis. Moreover, a rational investigation was done using different oxidants such as air and H2O2 with variables reaction conditions. The catalyst was active for liquid phase oxidation of vanillyl alcohol to vanillin with performance of 66% conversion and 71% selectivity using H2O2 in base free condition. And also, catalytic activity was significantly improved by 94% conversion with 86% selectivity to vanillin in liquid phase aerobic oxidation at the optimum reaction conditions. To expand the superiority of the catalyst, three times reusability study was also examined with appreciable catalytic activity.

    2016-11-01

    Survivorship after critical illness is an increasingly important health-care concern as ICU use continues to increase while ICU mortality is decreasing. Survivors of critical illness experience marked disability and impairments in physical and cognitive function that persist for years after their initial ICU stay. Newfound impairment is associated with increased health-care costs and use, reductions in health-related quality of life, and prolonged unemployment. Weakness, critical illness neuropathy and/or myopathy, and muscle atrophy are common in patients who are critically ill, with up to 80% of patients admitted to the ICU developing some form of neuromuscular dysfunction. ICU-acquired weakness (ICUAW) is associated with longer durations of mechanical ventilation and hospitalization, along with greater functional impairment for survivors. Although there is increasing recognition of ICUAW as a clinical entity, significant knowledge gaps exist concerning identifying patients at high risk for its development and understanding its role in long-term outcomes after critical illness. This review addresses the epidemiologic and pathophysiologic aspects of ICUAW; highlights the diagnostic challenges associated with its diagnosis in patients who are critically ill; and proposes, to our knowledge, a novel strategy for identifying ICUAW.

    Full Text Available In postgraduate interpreter training, the main objective of the course is to help trainees develop various competences, from linguistic, textual and cultural competence, to professional and specific interpreting competence. For simultaneous interpreting (SI, the main focus is on mastering the SI technique and strategies as well as on developing and strengthening communicative skills, which is discussed and illustrated with examples in the present paper. First, a brief overview is given of all the necessary competences of a professional interpreter with greater emphasis on specific interpreting competence for SI. In the second part of the paper, various approaches are described in terms of acquiring specific skills and strategies, specifically through a range of exercises. Besides interpreting entire speeches, practical courses should also consist of targeted exercises, which help trainees develop suitable coping strategies and mechanisms (later on almost automatisms, while at the same time "force" them to reflect on their individual learning process and interpreting performance. This provides a solid base on which trained interpreters can progress and develop their skills also after joining the professional sphere.

    Acquired immunodeficiency syndrome (AIDS) is reviewed for dental practitioners, with an emphasis on oral findings; the clinical course, diagnosis, reporting, treatment, prognosis, transmission, and epidemiology are also covered. HIV infection has an incubation period that may be associated with glandular fever, a prodrome called AIDS-Related Complex (ARC) characterized by lymphadenopathy, low fever, weight loss, night sweats, diarrhea, oral candidosis, nonproductive cough and recurrent infections. AIDS is characterized by opportunistic infections. Over 50% present with pneumocystis carinii pneumonia, 21% with Kaposi's sarcoma, and 6% have both. The AIDS virus causes direct neurological symptoms in some cases. Oral candidosis (thrush) in a young male without a local cause such as xerostomia or immune suppression is strongly suggestive of AIDS. Other oral manifestations are severe herpes simplex, varicella-zoster, Epstein-Barr virus, cytomegalovirus, venereal warts, aphthous ulceration, mycobacterial oral ulcers, oral histoplasmosis, sinusitis and osteomyelitis of the jaw. Hairy leukoplakia, usually seen on the lateral border of the tongue, is probably caused by Epstein-Barr virus. Kaposi's sarcoma, an endothelial cell tumor, is characteristic of AIDS, and in 50% of patients is oral or perioral. Cervical lymph node enlargement will be seen in those with ARC as well as AIDS. No guidelines have been issued by the Department of Health and Social Security for dental surgeons in the UK for reporting AIDS cases. Although HIV virions have been isolated from saliva, there are no known incidents of transmission via saliva. HIV is less likely to be transmitted by needle stick injuries than, for example hepatitis B (25% risk), especially if the blood is from a carrier rather than a full blown AIDS case.

    2013-05-07

    The mechanism of selective catalytic reduction of NOx by propene (C3H6-SCR) over the Cu/Ti0.7Zr0.3O2 catalyst was studied by in situ Fourier transform infrared (FTIR) spectroscopy and density functional theory (DFT) calculations. Especially, the formation and transformation of cyanide (-CN species) during the reaction was discussed. According to FTIR results, the excellent performance of the Cu/Ti0.7Zr0.3O2 catalyst in C3H6-SCR was attributed to the coexistence of two parallel pathways to produce N2 by the isocyanate (-NCO species) and -CN species intermediates. Besides the hydrolysis of the -NCO species, the reaction between the -CN species and nitrates and/or NO2 was also a crucial pathway for the NO reduction. On the basis of the DFT calculations on the energy of possible intermediates and transition states at the B3LYP/6-311 G (d, p) level of theory, the reaction channel of -CN species in the SCR reaction was identified and the role of -CN species as a crucial intermediate to generate N2 was also confirmed from the thermodynamics view. In combination of the FTIR and DFT results, a modified mechanism with two parallel pathways to produce N2 by the reaction of -NCO and -CN species over the Cu/Ti0.7Zr0.3O2 catalyst was proposed.

    Full Text Available Patients with ARCL-IIA harbor mutations in ATP6V0A2 that codes for an organelle proton pump. The ARCL-IIA syndrome characteristically presents a combined glycosylation defect affecting N-linked and O-linked glycosylations, differentiating it from other cutis laxa syndromes and classifying it as a Congenital Disorder of Glycosylation (ATP6V0A2-CDG. We studied two Mexican Mestizo patients with a clinical phenotype corresponding to an ARCL-IIA syndrome. Both patients presented abnormal transferrin (N-linked glycosylation but Patient 1 had a normal ApoCIII (O-linked glycosylation profile. Mutational screening of ATP6V0A2 using cDNA and genomic DNA revealed in Patient 1 a previously reported homozygous nonsense mutation c.187C>T (p.R63X associated with a novel clinical finding of a VSD. In Patient 2 we found a homozygous c.2293C>T (p.Q765X mutation that had been previously reported but found that it also altered RNA processing generating a novel transcript not previously identified (r.2176_2293del; p.F726Sfs*10. This is the first report to describe Mestizo patients with molecular diagnosis of ARCL-IIA/ATP6V0A2-CDG and to establish that their mutations are the first to be found in patients from different regions of the world and with different genetic backgrounds.

    Le cutis verticis gyrata (CVG), du cuir chevelu, est une maladie rare et évolutive de la peau du scalp. Elle est caractérisée par une hypertrophie et une hyperlaxité cutanée formant des plis semblables aux gyri du cortex cérébral. Nous présentons le cas d'une patiente de 21 ans atteinte de CVG primitif essentiel, ayant débuté à l’âge de 8 ans, au niveau du scalp et était d'aggravation progressive. La malade présentait une déformation du scalp avec de nombreux plis longitudinaux et transversaux. Sa demande était motivée par une gêne sociale et esthétique. Une résection chirurgicale de l'excédent cutané dans un plan transversal et longitudinal était réalisée. Le traitement de cette maladie est chirurgical, par l'excision des plis cutanés et remise en tension du scalp. Le nombre et la localisation des incisions doivent préserver la vascularisation des lambeaux de scalp et tenir compte du caractère évolutif de cette pathologie. PMID:25922634

Since then there has been much written regarding NHAP and its management despite the lack of well-designed studies in this patient population. The most characteristic features of patients with NHAP are the atypical presentation, which may lead to delay in diagnosis and therapy. The microbial etiology of pneumonia encompasses a wide spectrum that spans microbes recovered from patients with community-acquired pneumonia to organisms considered specific only to nosocomial settings. Decision to transfer a nursing home patient to an acute care facility depends on a host of factors, which include the level of staffing available at the nursing home, patients' advance directives, and complexity of treatment. The presence of risk factors for multidrug-resistant pathogens dictates approach to therapy. Prevention remains the cornerstone of reducing the incidence of disease. Despite the advance in medical services, mortality from NHAP remains high.

    We report two occupationally acquired cases of American cutaneous leishmaniasis (ACL): one accidental laboratory autoinoculation by contaminated needlestick while handling an ACL lesion sample, and one acquired during field studies on bird biology. Polymerase chain reaction (PCR) assays of patient lesions were positive for Leishmania, subgenus Viannia. One isolate was obtained by culture (from patient 2 biopsy samples) and characterized as Leishmania (Viannia) naiffi through an indirect immunofluorescence assay (IFA) with species-specific monoclonal antibodies (mAbs) and by multilocus enzyme electrophoresis (MLEE). Patients were successfully treated with N-methyl-glucamine. These two cases highlight the potential risks of laboratory and field work and the need to comply with strict biosafety procedures in daily routines. The swab collection method, coupled with PCR detection, has greatly improved ACL laboratory diagnosis. PMID:23227369

    Poolos, Nicholas P.; Johnston, Daniel

    2012-01-01

    Summary Ion channel dysfunction or “channelopathy” is a proven cause of epilepsy in the relatively uncommon genetic epilepsies with Mendelian inheritance. But numerous examples of acquired channelopathy in experimental animal models of epilepsy following brain injury have also been demonstrated. Our understanding of channelopathy has grown due to advances in electrophysiology techniques that have allowed the study of ion channels in the dendrites of pyramidal neurons in cortex and hippocampus. The apical dendrites of pyramidal neurons comprise the vast majority of neuronal surface membrane area, and thus the majority of the neuronal ion channel population. Investigation of dendritic ion channels has demonstrated remarkable plasticity in ion channel localization and biophysical properties in epilepsy, many of which produce hyperexcitability and may contribute to the development and maintenance of the epileptic state. Here we review recent advances in dendritic physiology and cell biology, and their relevance to epilepsy. PMID:23216577

    This study reviewed the clinical history and management of acquired growth arrest in the upper extremity in pediatric patients. The records of all patients presenting from 1996 to 2012 with radiographically proven acquired growth arrest were reviewed. Records were examined to determine the etiology and site of growth arrest, management, and complications. Patients with tumors or hereditary etiology were excluded. A total of 44 patients (24 boys and 20 girls) with 51 physeal arrests who presented at a mean age of 10.6 years (range, 0.8-18.2 years) were included in the study. The distal radius was the most common site (n=24), followed by the distal humerus (n=8), metacarpal (n=6), distal ulna (n=5), proximal humerus (n=4), radial head (n=3), and olecranon (n=1). Growth arrest was secondary to trauma (n=22), infection (n=11), idiopathy (n=6), inflammation (n=2), compartment syndrome (n=2), and avascular necrosis (n=1). Twenty-six patients (59%) underwent surgical intervention to address deformity caused by the physeal arrest. Operative procedures included ipsilateral unaffected bone epiphysiodesis (n=21), shortening osteotomy (n=10), lengthening osteotomy (n=8), excision of physeal bar or bone fragment (n=2), angular correction osteotomy (n=1), and creation of single bone forearm (n=1). Four complications occurred; 3 of these required additional procedures. Acquired upper extremity growth arrest usually is caused by trauma or infection, and the most frequent site is the distal radius. Growth disturbances due to premature arrest can be treated effectively with epiphysiodesis or osteotomy. In this series, the specific site of anatomic growth arrest was the primary factor in determining treatment. [Orthopedics. 2017; 40(1):e95-e103.]. Copyright 2016, SLACK Incorporated.

    2014-08-15

    Listeriosis is characterized by bacteremia or meningitis. We searched for listeriosis case series and outbreak investigations published in English by 2013, and assessed the strength of evidence for foodborne acquisition among patients who ate hospital food. We identified 30 reports from 13 countries. Among the case series, the median proportion of cases considered to be hospital-acquired was 25% (range, 9%-67%). The median number of outbreak-related illnesses considered to be hospital-acquired was 4.0 (range, 2-16). All patients were immunosuppressed in 18 of 24 (75%) reports with available data. Eight outbreak reports with strong evidence for foodborne acquisition in a hospital implicated sandwiches (3 reports), butter, precut celery, Camembert cheese, sausage, and tuna salad (1 report each). Foodborne acquisition of listeriosis among hospitalized patients is well documented internationally. The number of listeriosis cases could be reduced substantially by establishing hospital policies for safe food preparation for immunocompromised patients and by not serving them higher-risk foods.

    Nevus of Ota is a unilateral, asymptomatic cutaneous and mucosal hyperpigmentation of the face that is congenital or may appear during childhood. We present a case of symptomatic acquired nevus of Ota in an adult, associated with intense pruritus, not described in the literature so far. A 32-year-old woman presented with brownish mottled macules which appeared on her face progressively over 8 days, following the distribution of the first and second divisions of the left trigeminal nerve and partially covering the iris and sclera of the left eye. She reported an intense pruritus in this area. We performed a biopsy on the left forehead, which confirmed the diagnosis of nevus of Ota. Specific stains and immunohistochemistry revealed increased numbers of mast cells. Ophthalmological tests showed acute acquired melanocytosis of the left iris and sclera. The origin of the nevus is still unclear. Several hypotheses suggest a reactivation of melanocytes during their migration from the neural crest. The pruritus reported in our patient may be explained by the increased quantity of mast cells observed in the lesion and/or neuronal stimulation of the ophthalmic and maxillary divisions of the fifth cranial nerve.

    2016-01-01

    Acquired generalized lipodystrophy (AGL) is a rare disease thought to result from autoimmune destruction of adipose tissue. Peripheral T-cell lymphoma (PTCL) has been reported in two AGL patients. We report five additional cases of lymphoma in AGL, and analyze the role of underlying autoimmunity and recombinant human leptin (metreleptin) replacement in lymphoma development. Three patients developed lymphoma during metreleptin treatment (two PTCL and one ALK-positive anaplastic large cell lymphoma), and two developed lymphomas (mycosis fungoides and Burkitt lymphoma) without metreleptin. AGL is associated with high risk for lymphoma, especially PTCL. Autoimmunity likely contributes to this risk. Lymphoma developed with or without metreleptin, suggesting metreleptin does not directly cause lymphoma development; a theoretical role of metreleptin in lymphoma progression remains possible. For most patients with AGL and severe metabolic complications, the proven benefits of metreleptin on metabolic disease will likely outweigh theoretical risks of metreleptin in lymphoma development or progression.

  17. Bejel: acquirable only in childhood?

    Science.gov (United States)

    Rothschild, Bruce M; Rothschild, Christine; Naples, Virginia; Billard, Michel; Panero, Barbara

    2006-10-01

    Bejel clearly has a long history in the Middle East and the Sudan, but was it transmitted to Europe? As the major manifestation of bejel is presence of periosteal reaction in 20-40% of afflicted populations, absence of significant population frequency of periosteal reaction in Europe would exclude that diagnosis. Examination of skeletal populations from continental Europe revealed no significant periosteal reaction at the time of and immediately subsequent to the Crusades. Thus, there is no evidence for bejel in Europe, in spite of clear contact (the mechanism of bejel transmission in children) between warring groups, at least during the Crusades. This supports the hypothesis that bejel is a childhood-acquired disease and apparently cannot be contracted in adulthood.

    Full Text Available In this study, it has been purposed to share practice of event-scene administration, search and rescue and evacuation of injured and acquired experiences carried out throughout a building collapse. After an explosion at Diyarbakir Kurdoglu housings at 11 December 2006 about 08:20AM, five flats of an apartment that has five floors-ten flats were collapsed. Local military hospital ambulances, city ambulances, and fire-fighting vehicles arrived to event-place 10 minutes later. It has been found out that there were 13 people inside, 6 of which were children. Army rescue team arrived event-place about 01:30PM, then all non-professional persons has been sent away from region. Eight dead including five children, and five injured including one child have been taken out. Two people from close area have been also injured mildly due to the explosion. It has been found out that accident caused by boiler tank exploding. Sixth of total eight injured had only superficial wounds. Other two injured have been followed because of head trauma at first one and hepatic contusion and rib fracture at the other one. No complication observed after follow-up. Building collapses can create disaster potential according to the number of people inside and facilities of nearby region of the place accident taken place. The evaluation of the direction of building collapse during search and rescue operation would enhance possibility to reach more living in shorter time. Building collapses which can be considered as a miniature of big disaster potentials like earthquakes can be appraised as an important practical training and experience source on event-place administration, search and rescue operations and injured evacuation. We believe that share of the analysis and acquired experiences of this kind of studies would contribute interfering big disaster potentials. [TAF Prev Med Bull 2012; 11(2.000: 241-244

    2016-01-01

    This chapter starts with a description of imaging of inherited metabolic disorders, followed by a discussion on imaging of acquired toxic-metabolic disorders of the adult brain. Neuroimaging is crucial for the diagnosis and management of a number of inherited metabolic disorders. Among these, inherited white-matter disorders commonly affect both the nervous system and endocrine organs. Magnetic resonance imaging (MRI) has enabled new classifications of these disorders that have greatly enhanced both our diagnostic ability and our understanding of these complex disorders. Beyond the classic leukodystrophies, we are increasingly recognizing new hereditary leukoencephalopathies such as the hypomyelinating disorders. Conventional imaging can be unrevealing in some metabolic disorders, but proton magnetic resonance spectroscopy (MRS) may be able to directly visualize the metabolic abnormality in certain disorders. Hence, neuroimaging can enhance our understanding of pathogenesis, even in the absence of a pathologic specimen. This review aims to present pathognomonic brain MRI lesion patterns, the diagnostic capacity of proton MRS, and information from clinical and laboratory testing that can aid diagnosis. We demonstrate that applying an advanced neuroimaging approach enhances current diagnostics and management. Additional information on inherited and metabolic disorders of the brain can be found in Chapter 63 in the second volume of this series.

    Full Text Available Understanding how the mappings between orthography and phonology in alphabetic languages are learned, represented and processed has been enhanced by the cognitive neuropsychological investigation of patients with acquired reading and writing disorders. During the past decade, this methodology has been extended to understanding reading and writing in Chinese leading to new insights about language processing, dyslexia and dysgraphia. The aim of this paper is to review reports of patients who have acquired dyslexia and acquired dysgraphia in Chinese and describe the functional architecture of the reading and writing system. Our conclusion is that the unique features of Chinese script will determine the symptoms of acquired dyslexia and dysgraphia in Chinese.

    2011-01-01

    Cutaneous tuberculosis (tuberculosis cutis) is one of the extrapulmonary forms of tuberculosis, which may affect the skin only or co-exist with tuberculosis of other organs, particularly the lungs. We describe a case of lupus vulgaris in a 72-year-old male patient with a single lesion localized on his lower extremity, developing for 30 years before correct diagnosis and previously treated with topical steroids. Bacillus infection in other organs was not detected. Diagnosis of tuberculosis was made based on personal history, clinical picture, hypersensitivity to tuberculin, histopathology and polymerase chain reaction. A multidrug therapy with rifampicin, isoniazid and pyrazinamide resulted in regression of the lesion. The common lack of knowledge about the clinical picture of cutaneous tuberculosis causes its late diagnosis and treatment.

    Full Text Available Cutaneous tuberculosis because of its variability in presentation, wider differential diagnosis, and difficulty in obtaining microbiological confirmation continues to be the most challenging to diagnose for dermatologists in developing countries. Despite the evolution of sophisticated techniques such as polymerase chain reaction (PCR and enzyme-linked-immunosorbent serologic assay (ELISA, the sensitivity of new methods are not better than the isolation of Mycobacterium tuberculosum in culture. Even in the 21 st century, we rely on methods as old as the intradermal reaction purified protein derivative standard test and therapeutic trials, as diagnostic tools. We describe a case which has been diagnosed and treated as eczema by renowned physicians for 2 years. Incisional biopsy showed the presence of well-defined granulomas and ZN staining of the biopsy specimen showed the presence of acid fast bacilli; a trial of ATT (antitubercular therapy for 6 months lead to permanent cure of the lesion.

  4. Broad-spectrum acquired resistance in barley induced by the Pseudomonas pathosystem shares transcriptional components with Arabidopsis systemic acquired resistance.

    Colebrook, E H; Creissen, G; McGrann, G R D; Dreos, R; Lamb, C; Boyd, L A

    2012-05-01

    Inducible resistance responses play a central role in the defense of plants against pathogen attack. Acquired resistance (AR) is induced alongside defense toward primary attack, providing broad-spectrum protection against subsequent pathogen challenge. The localization and molecular basis of AR in cereals is poorly understood, in contrast with the well-characterized systemic acquired resistance (SAR) response in Arabidopsis. Here, we use Pseudomonas syringae as a biological inducer of AR in barley, providing a clear frame of reference to the Arabidopsis-P. syringae pathosystem. Inoculation of barley leaf tissue with the nonadapted P. syringae pv. tomato avrRpm1 (PstavrRpm1) induced an active local defense response. Furthermore, inoculation of barley with PstavrRpm1 resulted in the induction of broad-spectrum AR at a distance from the local lesion, "adjacent" AR, effective against compatible isolates of P. syringae and Magnaporthe oryzae. Global transcriptional profiling of this adjacent AR revealed similarities with the transcriptional profile of SAR in Arabidopsis, as well as transcripts previously associated with chemically induced AR in cereals, suggesting that AR in barley and SAR in Arabidopsis may be mediated by analogous pathways.

    for prevention of hospital-acquired hyponatraemia is an understanding of what determines plasma sodium concentration (P-[Na(+) ]) in the individual patient. P-[Na(+) ] is determined by balances of water and cations according to Edelman. This paper discusses the mechanisms influencing water and cation balances...... like Ringer-acetate/Ringer-lactate can increase the intracranial pressure dramatically. Consequently, 0.9 % NaCl is recommended as first-line fluid for such patients.

    The acquired alexia with agraphia syndrome is a conspicuous disorder of reading and writing in the absence of significant other language impairments that has mainly been recorded in adults. Pure cases are rare, with most patients displaying mild aphasic deficits. In children, acquired reading and writing disorders are generally reported as part of more encompassing aphasic syndromes affecting oral and written language equally, for example, Broca or Wernicke aphasia. Documented instances of predominant acquired reading and writing disorders in childhood are exceptional. We report an 11-year-old, right-handed boy who sustained a left temporoparieto-occipital hematoma following rupture of an arteriovenous malformation and who consecutively presented with the acquired alexia with agraphia syndrome associated with word-finding difficulties. Neuropsychologic and neurolinguistic data showed that there was no concomitant Gerstmann and/or angular gyrus syndrome. Th e recoveryfrom the anomia was quite favorable, but recovery of written language was more protracted and acted on the patient's further scholastic achievement. This case is reminiscent of a historical childhood case reported in 1939 and is consonant with adult cases in terms of lesion location and semiologic picture.

    The rate-limiting step of folding of the collagen triple helix is catalyzed by cyclophilin B (CypB). The G6R mutation in cyclophilin B found in the American Quarter Horse leads to autosomal recessive hyperelastosis cutis, also known as hereditary equine regional dermal asthenia. The mutant protein shows small structural changes in the region of the mutation at the side opposite the catalytic domain of CypB. The peptidylprolyl cis-trans isomerase activity of the mutant CypB is normal when analyzed in vitro. However, the biosynthesis of type I collagen in affected horse fibroblasts shows a delay in folding and secretion and a decrease in hydroxylysine and glucosyl-galactosyl hydroxylysine. This leads to changes in the structure of collagen fibrils in tendon, similar to those observed in P3H1 null mice. In contrast to cyclophilin B null mice, where little 3-hydroxylation was found in type I collagen, 3-hydroxylation of type I collagen in affected horses is normal. The mutation disrupts the interaction of cyclophilin B with the P-domain of calreticulin, with lysyl hydroxylase 1, and probably other proteins, such as the formation of the P3H1·CypB·cartilage-associated protein complex, resulting in less effective catalysis of the rate-limiting step in collagen folding in the rough endoplasmic reticulum.

    2000-10-01

    Stuttering is an uncommon presentation of acute stroke. Reported cases have often been associated with left sided cortical lesions, aphasia, and difficulties with other non-linguistic tests of rhythmic motor control. Three patients with subcortical lesions resulting in stuttering are discussed. In one patient the ability to perform time estimations with a computerised repetitive time estimation task was characterised. One patient had a pontine infarct with clinical evidence of cerebellar dysfunction. A second patient had a left basal ganglionic infarct and a disruption of timing estimation. A third patient had a left subcortical infarct and a mild aphasia. These findings expand the reported distribution of infarction that can result in acquired stuttering. Subcortical mechanisms of speech control and timing may contribute to the pathophysiology of acquired stuttering.

    Portosystemic shunts are enlarged vessels that form collateral pathological pathways between the splanchnic circulation and the systemic circulation. Although their causes are multifactorial, portosystemic shunts all have one mechanism in common-increased portal venous pressure, which diverts the blood flow from the gastrointestinal tract to the systemic circulation. Congenital and acquired collateral pathways have both been described in the literature. The aim of this pictorial essay was to discuss the distinct anatomic and imaging features of portosystemic shunts, as well as to provide a robust method of differentiating between acquired portosystemic shunts and similar pathologies, through the use of illustrations and schematic drawings. Imaging of portosystemic shunts provides subclinical markers of increased portal venous pressure. Therefore, radiologists play a crucial role in the identification of portosystemic shunts. Early detection of portosystemic shunts can allow ample time to perform endovascular shunt operations, which can relieve portal hypertension and prevent acute or chronic complications in at-risk patient populations.

    1985-01-01

    The electrophysiologic differences between chronic acquired demyelinative neuropathy and the demyelinative form of Charcot-Marie-Tooth disease have recently been reported. The present report extends these observations to include the genetically determined demyelinating neuropathies seen in metachromatic leukodystrophy, Krabbe's leukodystrophy, and Cockayne's syndrome. The electrophysiologic features of metachromatic leukodystrophy (five patients), Krabbe's (four patients), and Cockayne's syndrome (three patients) were all similar. There was uniform slowing of conduction (both in different nerves and in different nerve segments), and conduction block was not seen. These findings are consistent with a uniform degree of demyelination in multiple nerves and throughout the entire length of individual axons. Thus, uniform slowing of nerve conduction constitutes strong evidence for a familial demyelinative neuropathy, as opposed to the multifocal slowing seen in acute and chronic acquired demyelinative neuropathy.

    Gibson, Vanessa

    2015-11-18

    Pneumonia remains a significant cause of morbidity and mortality in the UK and yet the seriousness of the disease is underestimated. Pneumonia can be life-threatening because the delicate tissues of the alveoli and pulmonary capillaries are susceptible to damage from the inflammatory response. This damage leads to consolidation that prevents the diffusion of oxygen and carbon dioxide, and this in turn can lead to respiratory failure. This article summarises guidance on the diagnosis and management of community-acquired pneumonia, and also includes information on the prevention of pneumonia. This information should be valuable to nurses working in a variety of clinical areas since patients with community-acquired pneumonia are encountered in primary, intermediate, secondary and critical care.

    2013-07-01

    A key feature of the vertebrate adaptive immune system is acquired immune memory, whereby hosts launch a faster and heightened response when challenged by previously encountered pathogens, preventing full infection. Here, we use a mathematical model to explore the role of ecological and epidemiological processes in shaping selection for costly acquired immune memory. Applying the framework of adaptive dynamics to the classic SIR (Susceptible-Infected-Recovered) epidemiological model, we focus on the conditions that may lead hosts to evolve high levels of immunity. Linking our work to previous theory, we show how investment in immune memory may be greatest at long or intermediate host lifespans depending on whether immunity is long lasting. High initial costs to gain immunity are also found to be essential for a highly effective immune memory. We also find that high disease infectivity and sterility, but intermediate virulence and immune period, increase selection for immunity. Diversity in host populations through evolutionary branching is found to be possible but only for a limited range of parameter space. Our model suggests that specific ecological and epidemiological conditions have to be met for acquired immune memory to evolve.

    Full Text Available Acquired hemophilia A is a rare, but devastating bleeding disorder caused by spontaneous development of autoantibodies directed against coagulation factor VIII. In 40%-50% of patients it is associated with such conditions as the postpartum period, malignancy, use of medications, and autoimmune diseases; however, its cause is unknown in most cases. Acquired hemophilia A should be suspected in patients that present with a coagulation abnormality, and a negative personal and family history of bleeding. Herein we report 3 patients with acquired hemophilia A that had different underlying pathologies, clinical presentations, and therapeutic responses. Factor VIII inhibitor formation in case 1 occurred 6 months after giving birth; underlying disorders were not identified in cases 2 or 3. The bleeding phenotype in these patients’ ranged from no bleeding tendency with isolated prolongation of APTT (activated partial thromboplastin time to severe intramuscular hematoma and hemarthrosis necessitating recombinant activated factor VII infusion and blood components transfusion. Variable responses to immunosuppressive treatment were also observed.

The literature contains a diverse range of biological and psychological etiological theories. Acquired PE is commonly due to sexual performance anxiety, psychological or relationship problems, erectile dysfunction (ED), and occasionally prostatitis and hyperthyroidism, consistent with the predominant organic etiology of acquired PE, men with this complaint are usually older, have a higher mean BMI and a greater incidence of comorbid disease including hypertension, sexual desire disorder, diabetes mellitus, chronic prostatitis, and ED compared to lifelong, variable and subjective PE.

    Acquired fetal brain damage is suspected in cases of destruction of previously normally formed tissue, the primary cause of which is hypoxia. Fetal brain damage may occur as a consequence of acute or chronic maternal diseases, with acute diseases causing impairment of oxygen delivery to the fetal brain, and chronic diseases interfering with normal, placental development. Infections, metabolic diseases, feto-fetal transfusion syndrome, toxic agents, mechanical traumatic events, iatrogenic accidents, and space-occupying lesions may also qualify as pathologic conditions that initiate intrauterine brain damage. MR manifestations of acute fetal brain injury (such as hemorrhage or acute ischemic lesions) can easily be recognized, as they are hardly different from postnatal lesions. The availability of diffusion-weighted sequences enhances the sensitivity in recognizing acute ischemic lesions. Recent hemorrhages are usually readily depicted on T2 (*) sequences, where they display hypointense signals. Chronic fetal brain injury may be characterized by nonspecific changes that must be attributable to the presence of an acquired cerebral pathology. The workup in suspected acquired fetal brain injury also includes the assessment of extra-CNS organs that may be affected by an underlying pathology. Finally, the placenta, as the organ that mediates oxygen delivery from the maternal circulation to the fetus, must be examined on MR images.

Finally, the placenta, as the organ that mediates oxygen delivery from the maternal circulation to the fetus, must be examined on MR images.

    The purpose of this work was to determine whether cross-sectional area and coronal and sagittal diameter measurements of the trachea between inspiration and end-expiration on CT are significantly different between patients with acquired tracheomalacia and those without this condition. Inspiratory and end-expiratory CT scans of the trachea of 23 normal patients and 10 patients with acquired tracheomalacia were analyzed. Percent changes in cross-sectional area, coronal, and sagittal diameters were calculated. For patients with tracheomalacia, mean percent changes in the upper and middle trachea between inspiration and expiration were 49 and 44%; mean changes in the coronal and sagittal diameters in the upper and middle tracheal were 4 and 10% and 39 and 54%, respectively. Control group mean percent changes in the upper and middle tracheal area were 12 and 14%, respectively, and mean changes in the coronal and sagittal diameters in the upper and middle trachea were 4 and 4% and 11 and 13%, respectively. Significant differences were calculated for changes in cross-sectional area and sagittal diameter between groups (p 18% change in the upper trachea and 28% change in the midtrachea between inspiration and expiration were observed; the probability of tracheomalacia was 89-100%. The probability of tracheomalacia was > 89%, especially if the change in sagittal diameter was > 28%. By measuring changes in tracheal cross-sectional area and sagittal diameters between inspiratory and end-expiratory CT, a significant difference can be identified between normal patients and those with acquired tracheomalacia.

    Hypercholesterolaemia, characterised by raised blood cholesterol levels, is not a disease itself but a metabolic derangement that often contributes to many diseases, notably cardiovascular disease. In most cases, elevated cholesterol levels are associated with high-fat diet, especially saturated fat, coupled with an inactive lifestyle. Less commonly, raised cholesterol may be related to an inherited disorder, familial hypercholesterolaemia. This systematic review is only concerned with acquired hypercholesterolaemia. To assess the effects of low-fat diets for acquired hypercholesterolaemia and to investigate the incidence of adverse effects from low-fat dietary interventions. We planned to compare the relative effectiveness of low-fat diets with calorie-restricted diets for acquired hypercholesterolaemia. We also wanted to look into the relative effectiveness of low-fat diets and pharmacological interventions for acquired hypercholesterolaemia. Studies were obtained from computerised searches of The Cochrane Library, MEDLINE, EMBASE and databases of ongoing trials. Date of last search was February 2010. Otherwise healthy adults (equal to or greater than 18 years) with acquired (not familial) hypercholesterolaemia. We defined hypercholesterolaemia as either total cholesterol greater than 5.2 mmol/L, LDL-cholesterol greater than 3.0 mmol/L, HDL-cholesterol less than 1.0 mmol/L or a combination thereof, although investigators' definitions were also accepted. We wanted to include any low-fat dietary intervention, like low-fat and low-saturated fat diets, intended to lower serum total and LDL-cholesterol or to raise HDL-cholesterol. A low-fat diet was considered as a fat calorie intake less than 20% of the total calories. The minimum duration of the intervention had to be six months. We excluded studies in unhealthy people. Two authors were planned to independently assess risk of bias and extract data. No study met our inclusion criteria. Well designed, adequately

    2013-07-01

    Paragonimiasis is a parasitic lung infection caused by lung flukes of the genus Paragonimus, with most cases reported from Asia and caused by P. westermani following consumption of raw or undercooked crustaceans. With the exception of imported P. westermani cases in immigrants, in travelers returning from areas of disease endemicity, and in clusters of acquired cases following consumption of imported Asian crabs, human paragonimiasis caused by native lung flukes is rarely described in the United States, which has only one indigenous species of lung fluke, Paragonimus kellicotti. Clinicians should inquire about the consumption of raw or undercooked freshwater crabs by immigrants, expatriates, and returning travelers, and the consumption of raw or undercooked crayfish in U.S. freshwater river systems where P. kellicotti is endemic when evaluating patients presenting with unexplained fever, cough, rales, hemoptysis, pleural effusions, and peripheral eosinophilia. Diagnostic evaluation by specific parasitological, radiological, serological, and molecular methods will be required in order to differentiate paragonimiasis from tuberculosis, which is not uncommon in recent Asian immigrants. All cases of imported and locally acquired paragonimiasis will require treatment with oral praziquantel to avoid any potential pulmonary and cerebral complications of paragonimiasis, some of which may require surgical interventions.

    HYPOTHESIS: The goal of this work is to characterize the morphology and lipid composition of acquired cholesteatoma. We hypothesize that constitutive lipid membranes are present in the cholesteatoma and resemble those found in human skin stratum corneum. METHODS: We performed a comparative...... along a depth of more than 200 μm and resembles the stratum corneum of hyperorthokeratotic skin. Lipid compositional analyses of the cholesteatoma show the presence of all major lipid classes found in normal skin stratum corneum (ceramides, long chain fatty acids, and cholesterol). Consistent with this......, evaluation of Nile red and LAURDAN generalized polarization function images of the cholesteatoma show intercellular regions similar to normal skin stratum corneum in terms of lipid membrane packing and local water content. CONCLUSION: The investigations show the presence of an extremely thickened stratum...

  7. Systemic Acquired Resistance and Signal Transduction in Plant

    2003-01-01

    Systemic acquired resistance (SAR), known as the broad-spectrum, inducible plant immunity,is a defense response triggered by pathogen infection. The response starts from the recognition of plant resist-ance (R) with the corresponding avirulence (avr) gene from the pathogen. There are some genes for conver-gence of signals downstream of different R/avr interacting partners into a single signaling pathway. Salicylicacid (SA) is required for the induction of SAR and involved in transducing the signal in target tissues. The SAsignal is transduced through NPR1, a nuclear-localized protein that interacts with transcription factors thatare involved in regulating SA-mediated gene expression. Some chemicals that mimic natural signaling com-pounds can also activate SAR. The application of biochemical activators to agriculture for plant protection is anovel idea for developing green chemical pesticide.

    Full Text Available La inmunoterapia específica, junto con la evitación del alergeno y el tratamiento sintomático, forma parte del tratamiento de la patología alérgica. La modalidad más antigua, más conocida y mejor estudiada es la inmunoterapia subcutánea (ITSC, cuya eficacia tanto a corto como a largo plazo, ha sido ampliamente demostrada en numerosos estudios. Sin embargo, a pesar de haberse demostrado segura, no está exenta de efectos adversos y precisa ser administrada bajo supervisión de personal médico. Esto ha animado a buscar nuevas vías de administración de eficacia similar, con un buen perfil de seguridad, y de buena cumplimentación por parte del paciente. De las distintas alternativas estudiadas la más relevante es la inmunoterapia sublingual (ITSL. En ésta, se administra el antígeno en forma de gotas debajo de la lengua. Existen diferentes pautas de administración en función del alergeno implicado. La dosis óptima de tratamiento está aún sin determinar, hallándose en este momento en un rango amplio de dosis respecto a la inmunoterapia subcutánea. Su mecanismo de acción es poco conocido aunque en diversos estudios se han observado cambios inmunológicos. La ITSL ha mostrado un buen perfil de seguridad con escasos efectos secundarios, habitualmente de carácter local. Asimismo se han realizado distintos ensayos clínicos en los que se ha demostrado su eficacia en el tratamiento de la alergia respiratoria tanto en niños como en adultos. Por ello, aunque aún existen datos sin resolver respecto a esta vía de administración de inmunoterapia, ha sido propuesta por la OMS como una alternativa válida a la ITSC.Specific immunotherapy, together with avoidance of the allergen and symptomatic treatment, forms part of the treatment of allergic pathology.

    Highlights: • CT with multiplanar reformations can accurately display the sigmoid platet dehiscence. • The prevalence of sigmoid plate dehiscence was no significant difference among different age groups. • The size of sigmoid plate bony defects were not statistically different among different age groups. • The sigmoid plate dehiscence is more commonly a congenital than an acquired condition. - Abstract: Background and purpose: The imaging features of sigmoid plate dehiscence-induced pulsatile tinnitus have been presented. The origin of the sigmoid plate dehiscence, however, remains unclear. Our aim was to assess the prevalence and extent of sigmoid plate dehiscence on computed tomography (CT) images in multiple age groups to determine whether this condition is more likely to be congenital or acquired. Materials and methods: We retrospectively reviewed contrast-enhanced CT images of sigmoid plates of temporal bones in 504 patients. Each temporal bone was characterized as normal or dehiscent. Patients were then subcategorized into four age groups, and the prevalence and extent of dehiscent sigmoid plates in each group were calculated and compared. Results: Overall, 80 patients had sigmoid plate dehiscence, nine of whom had it bilaterally. In successively older age groups, the prevalences of sigmoid plate dehiscence were 18.9%, 20.1%, 14.5%, and 12.7%, respectively. Respective average anteroposterior bony defect diameters were 3.7 ± 1.7, 3.0 ± 1.3, 3.1 ± 1.5, and 3.0 ± 1.1 mm. Respective average vertical bony defect diameters were 3.6 ± 2.3, 2.6 ± 1.2, 3.2 ± 1.5, and 3.0 ± 1.7 mm. The prevalence and extent of sigmoid plate dehiscence were not statistically different among the four age groups. Conclusions: The similar radiologic prevalence and extent of dehiscent sigmoid plates among the age groups suggest that the dehiscence is more commonly a congenital than an acquired condition.

  10. Acquired prosopagnosia without word recognition deficits.

    It has long been suggested that face recognition relies on specialized mechanisms that are not involved in visual recognition of other object categories, including those that require expert, fine-grained discrimination at the exemplar level such as written words. But according to the recently proposed many-to-many theory of object recognition (MTMT), visual recognition of faces and words are carried out by common mechanisms [Behrmann, M., & Plaut, D. C. ( 2013 ). Distributed circuits, not circumscribed centers, mediate visual recognition. Trends in Cognitive Sciences, 17, 210-219]. MTMT acknowledges that face and word recognition are lateralized, but posits that the mechanisms that predominantly carry out face recognition still contribute to word recognition and vice versa. MTMT makes a key prediction, namely that acquired prosopagnosics should exhibit some measure of word recognition deficits. We tested this prediction by assessing written word recognition in five acquired prosopagnosic patients. Four patients had lesions limited to the right hemisphere while one had bilateral lesions with more pronounced lesions in the right hemisphere. The patients completed a total of seven word recognition tasks: two lexical decision tasks and five reading aloud tasks totalling more than 1200 trials. The performances of the four older patients (3 female, age range 50-64 years) were compared to those of 12 older controls (8 female, age range 56-66 years), while the performances of the younger prosopagnosic (male, 31 years) were compared to those of 14 younger controls (9 female, age range 20-33 years). We analysed all results at the single-patient level using Crawford's t-test. Across seven tasks, four prosopagnosics performed as quickly and accurately as controls. Our results demonstrate that acquired prosopagnosia can exist without word recognition deficits. These findings are inconsistent with a key prediction of MTMT. They instead support the hypothesis that face

    Most individuals who have survived an acquired brain injury present consequences affecting the sensorimotor, cognitive, affective or behavioural components. These deficits affect the proper performance of daily living activities. The aim of this study is to identify functional differences between individuals with unilateral acquired brain injury using functional independence, capacity, and performance of daily activities. Descriptive cross-sectional design with a sample of 58 people, with right-sided injury (n=14 TBI; n=15 stroke) or left-sided injury (n = 14 TBI, n = 15 stroke), right handed, and with a mean age of 47 years and time since onset of 4 ± 3.65 years. The functional assessment/functional independence measure (FIM/FAM) and the International Classification of Functioning (ICF) were used for the study. The data showed significant differences (P<.000), and a large size effect (dr=0.78) in the cross-sectional estimates, and point to fewer restrictions for patients with a lesion on their right side. The major differences were in the variables 'speaking' and 'receiving spoken messages' (ICF variables), and 'Expression', 'Writing' and 'intelligible speech' (FIM/FAM variables). In the linear regression analysis, the results showed that only 4 FIM/FAM variables, taken together, predict 44% of the ICF variance, which measures the ability of the individual, and up to 52% of the ICF, which measures the individual's performance. Gait alone predicts a 28% of the variance. It seems that individuals with acquired brain injury in the left hemisphere display important differences regarding functional and communication variables. The motor aspects are an important prognostic factor in functional rehabilitation. Copyright © 2013 Sociedad Española de Neurología. Published by Elsevier España, S.L.U. All rights reserved.

    The primary goal of triple arthrodesis for stage III and IV adult acquired flatfoot is to obtain a well-aligned plantigrade foot that will support the ankle in optimal alignment. Ancillary procedures including posterior muscle group lengthening, medial displacement calcaneal osteotomy, medial column stabilization, peroneus brevis tenotomy, or transfer and harvest of regional bone graft are often necessary to achieve adequate realignment. Image intensification is helpful in confirming optimal realignment before fixation. Results of triple arthrodesis are enhanced with adequate preparation of joint surfaces, bone graft/orthobiologics, 2-point fixation of all 3 tritarsal joints, and a vertical heel position.

    The face is a vital component of one’s personality and body image. There are a vast number of variables that influence recovery and rehabilitation from acquired facial trauma many of which are psychological in nature. The present paper presents the various psychological issues one comes across in facial trauma patients. These may range from body image issues to post-traumatic stress disorder symptoms accompanied by anxiety and depression. Issues related to facial and body image affecting social life and general quality of life are vital and the plastic surgeon should be aware of such issues and competent to deal with them in patients and families.

    Full Text Available Acquired hypopigmentary disorders comprise a significant group of disorders that affect Indians and Asians. The pigment disturbance in darker skin individuals can be very distressing to the patient and the family. These disorders cover a wide array of pathologies including infections, autoimmune processes, lymphoproliferative disorders, and sclerosing diseases. Histological diagnosis is particularly important because treatments for these diseases are varied and specific. This review will focus on histopathological diagnosis based on clinicopathological correlation for commonly encountered disorders such as leprosy, vitiligo, lichen sclerosus, pityriasis alba (PA, and pityriasis versicolor (PV. Atypical or uncommon clinical presentation of classic diseases such as hypopigmented mycosis fungoides (HMF and hypopigmented sarcoidosis are also included.

    Horner's syndrome (HS) is related to an interruption of the oculosympathetic nerve pathway. The classic clinical findings associated with this condition are ptosis, miosis, and enophthalmos. Heterochromia is typically described in congenital HS, but it is an uncommon finding in acquired HS. We report a case of post-traumatic HS associated with heterochromia. A literature review indicates that this type of heterochromia may be related to a reduction in the number of iris melanocytes. This mechanism may be the same in the physiological iris color modifications in adulthood.

    2008-07-01

    It is well known that the cases with savant syndrome, demonstrate outstanding mental capability despite coexisting severe mental disabilities. In many cases, savant skills are characterized by its domain-specificity, enhanced memory capability, and excessive focus on low-level perceptual processing. In addition, impaired integrative cognitive processing such as social cognition or executive function, restricted interest, and compulsive repetition of the same act are observed in savant individuals. All these are significantly relevant to the behavioral characteristics observed in individuals with autistic spectrum disorders (ASD). A neurocognitive model of savant syndrome should explain these cognitive features and the juxtaposition of outstanding talents with cognitive disabilities. In recent neuropsychological studies, Miller (1998) reported clinical cases of "acquired savant," i.e., patients who improved or newly acquired an artistic savant-like skill in the early stage of frontotemporal dementia (FTD). Although the relationship between an autistic savant and acquired savant remains to be elucidated, the advent of neuroimaging study of ASD and the clarification of FTD patients with savant-like skills may clarify the shared neural mechanisms of both types of talent. In this review, we classified current cognitive models of savant syndrome into the following 3 categories. (1) A hypermnesic model that suggests that savant skills develop from existing or dormant cognitive functions such as memory. However, recent findings obtained through neuropsychological examinations imply that savant individuals solve problems using a strategy that is fairly different from a non-autistic one. (2) A paradoxical functional facilitation model (Kapur, 1996) that offers possible explanations about how pathological states in the brain lead to development of prodigious skills. This model emphasizes the role of reciprocal inhibitory interaction among adjacent or distant cortical regions

    2003-01-01

    PIV Acquisition (PIVACQ) is a computer program for acquisition of data for particle-image velocimetry (PIV). In the PIV system for which PIVACQ was developed, small particles entrained in a flow are illuminated with a sheet of light from a pulsed laser. The illuminated region is monitored by a charge-coupled-device camera that operates in conjunction with a data-acquisition system that includes a frame grabber and a counter-timer board, both installed in a single computer. The camera operates in "frame-straddle" mode where a pair of images can be obtained closely spaced in time (on the order of microseconds). The frame grabber acquires image data from the camera and stores the data in the computer memory. The counter/timer board triggers the camera and synchronizes the pulsing of the laser with acquisition of data from the camera. PIVPROC coordinates all of these functions and provides a graphical user interface, through which the user can control the PIV data-acquisition system. PIVACQ enables the user to acquire a sequence of single-exposure images, display the images, process the images, and then save the images to the computer hard drive. PIVACQ works in conjunction with the PIVPROC program which processes the images of particles into the velocity field in the illuminated plane.

    People with communication impairments may face barriers to civic participation, with resulting marginalisation of individuals who wish to be actively involved. The investigation aimed to explore the experience of civically engaged adults with acquired neurological communication difficulties. Six people with acquired neurological communication difficulties were interviewed. Discussion included the definition of active citizenship, their civic involvement, motivations, related barriers and facilitators. Qualitative analysis was undertaken, with data categorised, coded and examined for recurring themes. All participants were active in disability-related organisations and four undertook wider civic roles. Motivations included activity being out with the home and wanting to effect change for themselves and the populations they represented. Disability group meetings were more positive experiences than broader community activities, which were associated with fatigue and frustration, commonly resulting from communication difficulties and unmet support needs. All participants identified a need for professional and public educational about disability and communication and made recommendations on content, methods and priority groups. For these participants civic engagement had positive and negative dimensions. Speech and language therapists should promote reduction of the barriers that impede the active citizenship rights of people with communication support needs. Civic participation may be a relevant measure of outcome in communication impaired populations.

    2015-01-01

    Community-acquired pneumonia is the sixth leading cause of death in the USA. Adherence to the 2007 Infectious Diseases Society of America/American Thoracic Society community-acquired pneumonia guidelines has been associated with improved clinical outcomes. However, choice between guideline-recommended treatments is at the discretion of the prescribing clinician. This review is intended to discuss the characteristics of these treatment options including dosing frequency, dose adjustment for renal/hepatic dysfunction, serious/common adverse events, drug interactions, lung penetration, pharmacokinetic-pharmacodynamic target and effect of obesity to help guide antimicrobial selection. An increasing portion of patients are receiving expanded empiric coverage for methicillin-resistant Staphylococcus aureus as recommended by the American Thoracic Society and Infectious Diseases Society of America for healthcare-associated pneumonia. However, this expanded coverage may not be achieving the desired improvements in clinical outcomes. We expect this increasingly diverse spectrum of patients with pneumonia to eventually result in the merger of these two guidelines to include all patients with pneumonia.

    Many animals acquire otherwise inaccessible food with the aid of sticks and occasionally water. As an exception, some reports suggest that elephants manipulate breathing through their trunks to acquire inaccessible food. Here, we report on two female Asian elephants (Elephas maximus) in Kamine Zoo, Japan, who regularly blew to drive food within their reach. We experimentally investigated this behaviour by placing foods in inaccessible places. The elephants blew the food until it came within accessible range. Once the food was within range, the elephants were increasingly less likely to blow as the distance to the food became shorter. One subject manipulated her blowing duration based on food distance: longer when the food was distant. These results suggest that the elephants used their breath to achieve goals: that is, they used it not only to retrieve the food but also to fine-tune the food position for easy grasping. We also observed individual differences in the elephants' aptitude for this technique, which altered the efficiency of food acquisition. Thus, we added a new example of spontaneous behaviour for achieving a goal in animals. The use of breath to drive food is probably unique to elephants, with their dexterous trunks and familiarity with manipulating the act of blowing, which is commonly employed for self-comfort and acoustic communication.

  3. Borders and Legal Criteria for Acquiring Nationality

    María Elósegui Itxaso

    2008-09-01

    Full Text Available Legal criteria for acquiring nationality are crucial in the integration of persons into society, since they provide access to the right to vote. Until now, the criteria most frequently used are those of ius soli (birth and ius sanguinis (nationality is inherited from the parents, which comply with previous anthropological approaches and which jurists accept without reflection, or consider to be unshakeable traditions.The author’s proposal in this article is to accept that some of these legal criteria should be reformed, though not in an anarchic manner. On one hand, some of the ethnic criteria may be respected, but on the other, the processes of acquiring nationality should be streamlined by accepting the desire of persons wanting to change their nationality on moving to a new country of residence. Meanwhile, we must establish channels of demand for accepting the democratic values and legal system of the welcoming country, as a result of which it would be fair to call for a prior learning period before the rights to nationality and suffrage are granted. The author also adds – and accepts as being a fundamental element – some of Habermas’ inclusion theses, though she stresses that this discourse should be organised into two specific, feasible legal solutions or rather, in a realistic manner.

    Full Text Available Acquired pigmentary disorders are group of heterogenous entities that share single, most significant, clinical feature, that is, dyspigmentation. Asians and Indians, in particular, are mostly affected. Although the classic morphologies and common treatment options of these conditions have been reviewed in the global dermatology literature, the value of histpathological evaluation has not been thoroughly explored. The importance of accurate diagnosis is emphasized here as the underlying diseases have varying etiologies that need to be addressed in order to effectively treat the dyspigmentation. In this review, we describe and discuss the utility of histology in the diagnostic work of hyperpigmentary disorders, and how, in many cases, it can lead to targeted and more effective therapy. We focus on the most common acquired pigmentary disorders seen in Indian patients as well as a few uncommon diseases with distinctive histological traits. Facial melanoses, including mimickers of melasma, are thoroughly explored. These diseases include lichen planus pigmentosus, discoid lupus erythematosus, drug-induced melanoses, hyperpigmentation due to exogenous substances, acanthosis nigricans, and macular amyloidosis.

    Full Text Available Abstract Background The recommendations outlined in the latest guidelines published by the Surgical Infection Society (SIS and the Infectious Disease Society of America (IDSA regarding the proper duration of antibiotic therapy in patients with intra-abdominal infections are limited and non-specific. This ambiguity is due mainly to the lack of clinical trials on the topic of optimal duration of therapy. It is well known that the overuse of antibiotics has several important consequences such as increased treatment costs, reduced clinical efficacy, and above all, the increased emergence of antibiotic-resistant pathogens. Ampicillin-Sulbactam is a commonly used "first line" antibiotic for intra-abdominal infections. Ertapenem and Ampicillin-sulbactam are recommended as primary treatment agents for localized peritonitis by both the SIS and IDSA guidelines. Methods/Design This study is a prospective multi-center randomized investigation. The study will be performed in the Departments of General, Emergency, and Transplant Surgery of Sant'Orsola-Malpighi University Hospital in Bologna, Italy, in the General Surgery Department of the Ospedali Riuniti of Bergamo, Italy, and in the Trauma and Emergency Surgery Department of Maggiore Hospital in Bologna, Italy, and will be conducted by all surgeons willing to participate in the study. The inclusion period of the study will take approximately two years before the planned number of 142 enrolled patients is reached. Discussion Ertapenem and Ampicillin-sulbactam are recommended both as primary treatment agents for localized peritonitis by both the SIS and IDSA guidelines. As one of the discussed topic is the optimal duration of the antibiotic therapy and this ambiguity is due mainly to the lack of clinical trials on the topic, the present study aims for obtain precise data.

    Epitaxial thin films of the half-metallic X{sub a}-compound Mn{sub 2}CoGa (Hg{sub 2}CuTi prototype) were prepared by dc magnetron co-sputtering with different heat treatments on MgO (001) substrates. High-quality lms with a bulk magnetization of 1.95(5) {mu}{sub }B per unit cell were obtained. The average Mn magnetic moment and the Co moment are parallel, in agreement with theory. The x-ray magnetic circular dichroism spectra agree with calculations based on density functional theory and reveal the antiparallel alignment of the two inequivalent Mn moments. X-ray magnetic linear dichroism allows to distinguish between itinerant and localized Mn moments. It is shown that one of the two Mn moments has localized character, whereas the other Mn moment and the Co moment are itinerant.

    Local architecture refers to structures built in the countryside,such as temples,memorial halls,residences, stores,pavilions, bridges,decorated archways, and wells. Because these structures were all built by focal craftsmen and villagers in the traditional local style, they are generally called local architecture.

  8. [Merits of acquiring ISO15189 accreditation].

    Kitagawa, Masami

    2010-01-01

    In Japan, an ISO15189 accreditation system was started in 2005. To date, 47 hospitals have been accredited. In this session, I will present the merits of acquiring accreditation regarding ISO15189 based on our experience. Our hospital has 263 beds. The Clinical Examination Section consists of 12 staff (including 5 part-time workers): 7 in change of sample examination and 5 in charge of physiological examination. The annual number of samples is approximately 150,000. Samples collected on health checkups account for 90%. To improve the quality and service, assessment by third persons has been positively utilized in our hospital. Accreditation regarding ISO9001, ISO14001, ISO27001, privacy mark, hospital function assessment, the functional assessment of "ningen-dock"/health checkup hospitals, labor/hygiene service function assessment, and ISO15189 has been acquired. Patients may not recognize ISO. So, it must be utilized, considering that the acquisition of accreditation is not a goal but a starting point. Furthermore, cost-performance should be improved to achieve utilization-related merits. It is important to not only acquire accreditation but also help clinical staff and patients become aware of some changes/merits. Patients may consult a hospital for the following reasons: confidence in the hospital, and the staffs kind/polite attitudes. Long-term management strategies should be established without pursuing only short-term profits. I will introduce several merits of acquiring accreditation regarding ISO15189. Initially, incidental conditions for bids and appeal points include accreditation regarding ISO15189. Our corporation has participated in some competitive bids regarding health checkup business. In some companies, the bid conditions included ISO acquisition. In our hospital, clinical trials have been positively carried out. For participation in trials, hospitals must pass an institutional examination. However, ISO acquisition facilitates the preparation of

    AIM: Acquired hepatocerebral degeneration (AHD) is an exceptional type of hepatic encephalopathies (HE). It is characterized by neuropsychiatric and extrapyramidal symptomathology similar to that seen in hepatolenticular degeneration (Wilson's disease). In this paper, we report a case of AHD with unusual presenting features.METHODS: A 28-year-old man with AHD was described and the literature was reviewed.RESULTS: The man had a history of HBV-related liver cirrhosis. He was admitted to our hospital with apathy,dysarthria, mild consciousness impairment and extrapyramidal symptoms after hematemesis. By review of the literature,cases with AHD often did not present consciousness impairment. So our case was once diagnosed incorrectly as Wilson's disease.CONCLUSION: AHD is a rare syndrome and its variable clinical manifestations make it difficult to be diagnosed.But we believe that extensive examination and thorough understanding of the disease are beneficial to a correct diagnosis. Moreover, biocoene is effective in treating the case.

    Full Text Available In December 1992. a meeting was convened in Toronto to develop guidelines for the initial treatment of hospital acquired pneumonia. Issues considered related lo the patient. the possible drugs used for treatment, and the pathogen(s. From the perspective of the patient. the two major issues were the presence or absence of risk factors for specific microbial pathogens and the severity of illness upon clinical presentation, Criteria for defining severly ill patients were developed and are presented in this paper. Drug and pathogen related issues focused on selection of antimicrobial agents thal would provide coverage for the likely pathogens. Concern was also expressed regarding use of aminoglycosides as single-agent treatment of Gram-negative infections in the lung. and the issue of monotherapy versus combination therapy of Pseudomonas aeruginosa infections was discussed. The use of various diagnostic tests was briefly reviewed. including the protected specimen brush and bronchoalveolar lavage. Treatment regimens are presented in tabular format.

    Determinants of synesthetic color choice for the Japanese logographic script, Kanji, were studied. The study investigated how synesthetic colors for Kanji characters, which are usually acquired later in life than other types of graphemes in Japanese language (phonetic characters called Hiragana and Katakana, and Arabic digits), are influenced by linguistic properties such as phonology, orthography, and meaning. Of central interest was a hypothesized generalization process from synesthetic colors for graphemes, learned prior to acquisition of Kanji, to Kanji characters learned later. Results revealed that color choices for Kanji characters depend on meaning and phonological information. Some results suggested that colors are generalized from Hiragana characters and Arabic digits to Kanji characters via phonology and meaning, respectively. Little influence of orthographic information was observed. The findings and approach of this study contributes to a clarification of the mechanism underlying grapheme-color synesthesia, especially in terms of its relationship to normal language processing.

  12. Acquiring Correct Knowledge for Natural Language Generation

    Reiter, E; Sripada, S G; 10.1613/jair.1176

    2011-01-01

    Natural language generation (NLG) systems are computer software systems that produce texts in English and other human languages, often from non-linguistic input data. NLG systems, like most AI systems, need substantial amounts of knowledge. However, our experience in two NLG projects suggests that it is difficult to acquire correct knowledge for NLG systems; indeed, every knowledge acquisition (KA) technique we tried had significant problems. In general terms, these problems were due to the complexity, novelty, and poorly understood nature of the tasks our systems attempted, and were worsened by the fact that people write so differently. This meant in particular that corpus-based KA approaches suffered because it was impossible to assemble a sizable corpus of high-quality consistent manually written texts in our domains; and structured expert-oriented KA techniques suffered because experts disagreed and because we could not get enough information about special and unusual cases to build robust systems. We bel...

    The acquired immunodeficiency syndrome (AIDS) is a major health problem for gay men in the United States. About three fourths of all reported cases have occurred in this population, and the number is projected to double in the next year. In Manhattan and San Francisco, AIDS is now the leading cause of premature mortality in men aged 25 to 44 years who have never married. In a sample of a cohort of gay men enrolled in a San Francisco clinic, 2.7% of the men had the syndrome and 26% had related conditions in 1984. Antibody to human T-lymphotropic virus, type III/lymphadenopathy-associated virus was found in sera from 67% of the men, including 58% of asymptomatic men. Behavioral factors associated with an increased risk of AIDS include large numbers of sexual partners, receptive anal intercourse, and "fisting." The adoption of safer lifestyles is currently the basis of attempts to control the syndrome in gay men.

  14. Time dysperception perspective for acquired brain injury

    2014-01-01

    Full Text Available Distortions of time perception are presented by a number of neuropsychiatric disorders. Here we survey timing abilities in clinical populations with acquired brain injuries in key cerebral areas recently implicated in human studies of timing. We purposely analyzed the complex relationship between cognitive and contextual factors involved in time estimation, as to characterize the correlation between timed and other cognitive behaviors in each group. We assume that interval timing is a solid construct to study cognitive dysfunctions following brain injury, as timing performance is a sensitive metric of information processing, while temporal cognition has the potential of influencing a wide range of cognitive processes. Moreover, temporal performance is a sensitive assay of damage to the underlying neural substrate after a brain insult. Further research in neurological and psychiatric patients will definitively answer the question of whether time distortions are manifestations of cognitive and behavioral symptoms of brain damage and definitively clarify their mechanisms.

    2007-08-01

    Dermal melanocytoses comprise a variety of congenital and acquired conditions characterized by a sparse population of intradermal dendritic, variably pigmented, spindle-shaped melanocytes. While Mongolian spot, Ota's and Ito's nevi are usually present at birth or appear around puberty; acquired dermal melanocytoses that appear in adult life are extremely rare. They include the facial lesions of acquired bilateral nevus of Ota-like macules, also named Hori's nevus, and the acquired unilateral nevus of Ota, also known as Sun's nevus. Uncommon extrafacial examples of acquired dermal melanocytoses include lesions involving upper extremities, wrist, back, lower extremities and dorsal aspects of the hands and feet. They are more prevalent among Asian women. In general, dermal melanocytoses are rare lesions in Caucasian patients and acquired variants are exceedingly uncommon. We report a rare example of acquired Ito's nevus that appeared in a Caucasian elderly woman and review the literature about acquired dermal melanocytoses.

    Full Text Available Purpose: It is well known that congenital hypothyroidism can cause hearing loss. However, conflicting results were found in studies investigating hearing functions in acquired hypothyroidism. Therefore, we evaluated the audiometric findings in patients with acquired hypothyroidism. Material and Method: The study included 58 patients with hypothyroidism and age- and gender-matched 34 healthy controls. Twenty eight (48.27% patients had subclinical hypothyroidism, and 30 (51.73% had obvious hypothyroidism. All subjects had a normal otoscopic examination and tympanometry. Pure tone audiometry at 250, 500, 1000, 2000, 4000, 6000, and 8000 Hertz (Hz was performed in both groups. Blood pressure measurements and the levels of plasma electrolytes, lipids and vitamin B12 were available in all subjects. Results: Hypothyroidism group and control group were similar with respect to systolic and diastolic blood pressures and plasma glucose, lipid, vitamin B12, calcium, sodium, potassium, and chloride levels. Significantly higher audiometric thresholds (dB at 250 (10 (0-45 vs. 5 (0-15, p<0.001 and 500 Hz (10 (0-40 vs. 10 (-5-15, p=0.003 were recorded in hypothyroid patients compared to that in healthy controls. Hearing thresholds at 250 and 500 Hz correlated positively with thyroid-stimulating hormone (TSH, and negatively with free triiodothyronine and free thyroxine. Subclinical hypothyroid patients had a higher hearing threshold at 250 Hz than healthy controls (p=0.001. Discussion: Our study demonstrated that hearing ability decreases in hypothyroidism, even in subclinical hypothyroidism. The changes in TSH and thyroid hormone levels seem to be directly related to the hearing loss in this population of patients.

    Acquired epilepsy is frequently associated with structural lesions after trauma, stroke, and infections. Although seizures are often difficult to treat, there is no clinically applicable strategy to prevent the development of epilepsy in patients at risk. We have recently shown that vascular injury is associated with activation of albumin-mediated transforming growth factor β (TGF-β) signaling, and followed by local inflammatory response and epileptiform activity ex vivo. Here we investigated albumin-mediated TGF-β signaling and tested the efficacy of blocking the TGF-β pathway in preventing epilepsy. We addressed the role of TGF-β signaling in epileptogenesis in 2 different rat models of vascular injury, combining in vitro and in vivo biochemical assays, gene expression, and magnetic resonance and direct optical imaging for blood-brain barrier permeability and vascular reactivity. Long-term electrocorticographic recordings were acquired in freely behaving animals. We demonstrate that serum-derived albumin preferentially induces activation of the activin receptor-like kinase 5 pathway of TGF-β receptor I in astrocytes. We further show that the angiotensin II type 1 receptor antagonist, losartan, previously identified as a blocker of peripheral TGF-β signaling, effectively blocks albumin-induced TGF-β activation in the brain. Most importantly, losartan prevents the development of delayed recurrent spontaneous seizures, an effect that persists weeks after drug withdrawal. TGF-β signaling, activated in astrocytes by serum-derived albumin, is involved in epileptogenesis. We propose losartan, a drug approved by the US Food and Drug Administration, as an efficient antiepileptogenic therapy for epilepsy associated with vascular injury. © 2014 American Neurological Association.

  6. Community-acquired pneumonia; Ambulant erworbene Pneumonien

    The diagnosis of community-acquired pneumonia (CAP) is often not possible based only on the clinical symptoms and biochemical parameters. For every patient with the suspicion of CAP, a chest radiograph in two planes should be carried out. Additionally, a risk stratification for the decision between outpatient therapy or hospitalization is recommended. Based on the evaluation of the different radiological patterns as well as their extent and distribution, a rough allocation to so-called pathogen groups as well as a differentiation between viral and bacterial infections are possible; however, because different pathogens cause different patterns an accurate correlation is not feasible by relying purely on imaging. The radiological findings serve as proof or exclusion of pneumonia and can also be used to evaluate the extent of the disease (e.g. monolobular, multilobular, unilateral or bilateral). In cases of prolonged disease, suspicion of complications (e.g. pleural effusion or empyema, necrotizing pneumonia or abscess) or comorbid conditions (e.g. underlying pulmonary or mediastinal diseases) computed tomography is an important diagnostic tool in addition to chest radiography. Ultrasound is often used to diagnose pleural processes (e.g. parapneumonic effusion or pleural empyema). (orig.)

    Full Text Available We review the current status of local helioseismology, covering both theoretical and observational results. After a brief introduction to solar oscillations and wave propagation through inhomogeneous media, we describe the main techniques of local helioseismology: Fourier-Hankel decomposition, ring-diagram analysis, time-distance helioseismology, helioseismic holography, and direct modeling. We discuss local helioseismology of large-scale flows, the solar-cycle dependence of these flows, perturbations associated with regions of magnetic activity, and solar supergranulation.

    2005-11-01

    Bullous diseases of the oral cavity cause painful erosion. They must be distinguished from aphthae and vesicles which may have a similar presentation. Acute, chronic and congenital conditions are recognized. Acute lesions may involve a polymorphous oral erhythema which has an polymorphous erythematous presentation or toxidermia (Stevens-Johnson syndrome, Lyell syndrome, fixed pigmented erythema). Examination of the skin and history taking are the keys to diagnosis. Patients with chronic bullous diseases may have a congenital condition (bullous epidermolysis or lymphangioma) suggested by the age at onset and the clinical presentation. Acquired chronic bullous diseases include lichen planus and autoimmune bullous diseases. Careful examination is essential to identify mucosal or cutaneous involvement and to obtain a biopsy for histological examination. Search for antibodies deposited in the perilesional mucosa is necessary. Chronic erosive gingivitis is a frequent presentation. Most of the patients have cicatricial pemphigoid, lichen planus, and more rarely pemphigus. The pinch sign is highly discriminative to differentiate the cause of this syndrome. Symptomatic treatment of bullous lesions of the oral cavity include adapted diet and correct and early use of antalgesics.

    Almirall, Jordi; Blanquer, José; Bello, Salvador

    2014-06-01

    Recent studies have left absolutely no doubt that tobacco increases susceptibility to bacterial lung infection, even in passive smokers. This relationship also shows a dose-response effect, since the risk reduces spectacularly 10 years after giving up smoking, returning to the level of non-smokers. Streptococcus pneumoniae is the causative microorganism responsible for community-acquired pneumonia (CAP) most frequently associated with smoking, particularly in invasive pneumococcal disease and septic shock. It is not clear how it acts on the progress of pneumonia, but there is evidence to suggest that the prognosis for pneumococcal pneumonia is worse. In CAP caused by Legionella pneumophila, it has also been observed that smoking is the most important risk factor, with the risk rising 121% for each pack of cigarettes smoked a day. Tobacco use may also favor diseases that are also known risk factors for CAP, such as periodontal disease and upper respiratory viral infections. By way of prevention, while giving up smoking should always be proposed, the use of the pneumococcal vaccine is also recommended, regardless of the presence of other comorbidities.

    2016-01-01

    Full Text Available Background: The course of human immunodeficiency virus infection and the acquired immunodeficiency syndrome can be complicated by a variety of endocrine abnormalities, including abnormalities of thyroid gland. Materials and Methods: This study was designed to understand the spectrum of pathology of thyroid in Indian patients with AIDS. The present study describes the findings of retrospective autopsy findings of 158 patients with AIDS which revealed infectious diseases from a time period before the use of highly active antiretroviral regimen. Results: A wide range of bacterial, fungal, and viral infections were observed. Tuberculosis was recorded in 14 (09% patients, Cryptococcus neoformans in 11 (7% patients and cytomegalovirus in 3 (2% patients. Hashimoto's thyroiditis and lymphocytic thyroiditis were seen in 02 (01% patients each. One patient had dual infection comprising of tuberculosis and cytomegalovirus infection. The other microscopic findings observed were goiter (2 patients, interstitial fibrosis in thyroid (7 patients, and calcification in thyroid (8 patients. Conclusions: Abnormalities of thyroid are uncommon findings in patients with HIV infection however several case reports of thyroid involvement by infectious agents and neoplasm are described in these patients; hence patients with HIV infection should be closely followed up for development of goiter or abnormalities of thyroid functions.

    The neocortex is the site of origin of several forms of acquired epilepsy. Here we provide a brief review of experimental models that were recently developed to study neocortical epileptogenesis as well as some major results obtained with these methods. Most of neocortical seizures appear to be nocturnal and it is known that neuronal activities reveal high levels of synchrony during slow-wave sleep. Therefore, we start the review with a description of mechanisms of neuronal synchronization and major forms of synchronized normal and pathological activities. Then, we describe three experimental models of seizures and epileptogenesis: ketamine-xylazine anesthesia as feline seizure triggered factor, cortical undercut as cortical penetrating wound model and neocortical kindling. Besides specific technical details describing these models we also provide major features of pathological brain activities recorded during epileptogenesis and seizures. The most common feature of all models of neocortical epileptogenesis is the increased duration of network silent states that up-regulates neuronal excitability and eventually leads to epilepsy.

    2014-01-01

    Cognitive models propose a hierarchy of parallel processing stages in face perception, and functional neuroimaging shows a network of regions involved in face processing. Reflecting this, acquired prosopagnosia is not a single entity but a family of disorders with different anatomic lesions and different functional deficits. One classic distinction is between an apperceptive variant, in which there is impaired perception of facial structure, and an associative/amnestic variant, in which perception is relatively intact, with subsequent problems matching perception to facial memories, because of either disconnection or loss of those memories. These disorders also have to be distinguished from people-specific amnesia, a multimodal impairment, and prosop-anomia, in which familiarity with faces is preserved but access to names is disrupted. These different disorders can be conceived as specific deficits at different processing stages in cognitive models, and suggests that these functional stages may have distinct neuroanatomic substrates. It remains to be seen whether a similar anatomic and functional variability is present in developmental prosopagnosia.

  13. Acquired Hemophilia A successfully treated with rituximab

    2015-02-01

    Full Text Available Acquired hemophilia A (AHA is a rare bleeding disorder due to the development of specific autoantibodies against factor VIII. The anti-CD20 monoclonal antibody Rituximab has been proven to be effective in  obtaining a long-term suppression of inhibitors of AHA,  besides other immunosuppressive standard treatments. Here we describe a case of idiopathic AHA in a 60-year old man successfully treated with rituximab. He showed a complete clinical response with  a normalization of clotting  parameters after 5 weekly courses of rituximab given at a dose of 375 mg/sqm. , but after stopping rituximab, an initial worsening of coagulation  parameters  induced the addition of 3 further courses. At present, the patient is in complete clinical and hematological remission after 200 days.  This case confirms that Rituximab may be a safe and useful tool to treat AHA and, a prolonged administration can overcome the initial resistance. However, the precise position of this drug in the therapeutic strategy (first or second-line, alone or in combination with other drugs remains to be established and warrants further investigation.

    Acquired immune deficiency syndrome (AIDS) is an immune deficiency disease. The etiology of hyperthyroidism, which can also be immune-related, is usually divided into six classical categories, including hypophyseal, hypothalamic, thyroid, neoplastic, autoimmune and inflammatory hyperthyroidism. Hyperthyroidism is a rare complication of highly active antimicrobial therapy (HAART) for human immunodeficiency virus (HIV). Hyperthyroidism caused directly by AIDS has not been previously reported. A 29-year-old man who complained of dyspnea and asthenia for 1 month, recurrent fever for more than 20 days, and breathlessness for 1 week was admitted to our hospital. The thyroid function test showed that the level of free thyroxine (FT4) was higher than normal and that the level of thyroid-stimulating hormone (TSH) was below normal. He was diagnosed with hyperthyroidism. Additional investigations revealed a low serum albumin level and chest infection, along with diffuse lung fibrosis. Within 1 month, he experienced significant weight loss, no hand tremors, intolerance of heat, and perspiration proneness. We recommended an HIV examination; subsequently, AIDS was diagnosed based on the laboratory parameters. This is the first reported case of hyperthyroidism caused by AIDS. AIDS may cause hyperthyroidism by immunization regulation with complex, atypical, and easily ignored symptoms. Although hyperthyroidism is rare in patients with AIDS, clinicians should be aware of this potential interaction and should carefully monitor thyroid function in HIV-positive patients.

  19. Chapter 22: Hereditary and acquired angioedema.

    Georgy, Mary S; Pongracic, Jacqueline A

    2012-01-01

    Hereditary angioedema (HAE) is an autosomal dominant disorder defined by a deficiency of functional C1 esterase inhibitor (C1-INH). Acquired angioedema (AAE) is caused by either consumption (type 1) or inactivation (type 2) of CI-INH. Both HAE and AAE can be life-threatening. The screening test for both conditions is complement component C4, which is low to absent at times of angioedema or during quiescent periods. A useful test to differentiate HAE from AAE is C1q protein, which is normal in HAE and low in AAE. There are three types of HAE: type 1 HAE is most common, occurring in ∼85% of patients and characterized by decreased production of C1-INH, resulting in reduced functional activity to 5-30% of normal. In type 2, which occurs in 15% of cases, C1-INH is detectable in normal or elevated quantities but is dysfunctional. Finally, type 3, which is rare and almost exclusively occurs in women, is estrogen dependent and associated with normal CI-INH and C4 levels. One-third of these patients have a gain-of-function mutation in clotting factor XII leading to kallikrein-driven bradykinin production. Although the anabolic steroid, danazol, is useful in increasing the concentration of C4 and reducing the episodes of angioedema in HAE and AAE, it has expected adverse effects. Fortunately, disease-specific therapies are available and include C1-INH enzyme for i.v. infusion either acutely or empirically, ecallantide, an inhibitor of kallikrein, and icatibant, a bradykinin B2-receptor antagonist, both approved for acute angioedema and administered, subcutaneously.

    Background Cytomegalovirus (CMV) retinitis is the most severe intraocular complication that results in total retinal destruction and loss of visual acuity in patients with acquired immunodeficiency syndrome (AIDS). This study aimed to investigate the fundus characteristics, systemic manifestations and therapeutic outcomes of CMV retinitis associated with AIDS.Methods It was a retrospective case series. CMV retinitis was present in 39 eyes (25 patients). Best corrected visual acuities, anterior segment, fundus features, fundus fluorescence angiography (FFA) and CD4+ T-lymphocyte counts of the patients with CMV retinitis associated with AIDS were analyzed. Intravitreal injections of ganciclovir (400 μg) were performed in 4 eyes (2 patients).Results Retinal vasculitis, dense, full-thickness, yellow-white lesions along vascular distribution with irregular granules at the border, and hemorrhage on the retinal surface were present in 28 eyes. The vitreous was clear or mildly opaque.Late stage of the retinopathy was demonstrated in 8 eyes characterized as atrophic retina, sclerotic and attenuated vessels, retinal pigment epithelium (RPE) atrophy, and optic nerve atrophy. Retinal detachment was found in 3 eyes. The average CD4+ T-lymphocyte count in peripheral blood of the patients with CMV retinitis was (30.6±25.3) ×106/L (range,(0-85) × 106/L). After intravitreal injections of ganciclovir, visual acuity was improved and fundus lesions regressed.Conclusions CMV retinitis is the most severe and the most common intraocular complication in patients with AIDS. For the patients with yellow-white retinal lesions, hemorrhage and retinal vasculitis without clear cause, human immunodeficiency virus (HIV) serology should be performed. Routine eye examination is also indicated in HIV positive patients.

    Case reports have suggested that perception of the eye region may be impaired more than that of other facial regions in acquired prosopagnosia. However, it is unclear how frequently this occurs, whether such impairments are specific to a certain anatomic subtype of prosopagnosia, and whether these impairments are related to changes in the scanning of faces. We studied a large cohort of 11 subjects with this rare disorder, who had a variety of occipitotemporal or anterior temporal lesions, both unilateral and bilateral. Lesions were characterized by functional and structural imaging. Subjects performed a perceptual discrimination test in which they had to discriminate changes in feature position, shape, or external contour. Test conditions were manipulated to stress focused or divided attention across the whole face. In a second experiment we recorded eye movements while subjects performed a face memory task. We found that greater impairment for eye processing was more typical of subjects with occipitotemporal lesions than those with anterior temporal lesions. This eye selectivity was evident for both eye position and shape, with no evidence of an upper/lower difference for external contour. A greater impairment for eye processing was more apparent under attentionally more demanding conditions. Despite these perceptual deficits, most subjects showed a normal tendency to scan the eyes more than the mouth. We conclude that occipitotemporal lesions are associated with a partially selective processing loss for eye information and that this deficit may be linked to loss of the right fusiform face area, which has been shown to have activity patterns that emphasize the eye region.

    2014-10-01

    Full Text Available A mathematical model SEIA (susceptible-exposed-infectious-AIDS infected with vertical transmission of AIDS epidemic is formulated. AIDS is one of the largest health problems, the world is currently facing. Even with anti-retroviral therapies (ART, many resource-constrained countries are unable to meet the treatment needs of their infected populations. We consider a function of number of AIDS cases in a community with an inverse relation. A stated theorem with proof and an example to illustrate it, is given to find the equilibrium points of the model. The disease-free equilibrium of the model is investigated by finding next generation matrix and basic reproduction number R0 of the model. The disease-free equilibrium of the AIDS model system is locally asymptotically stable if R0⩽1 and unstable if R0>1. Finally, numerical simulations are presented to illustrate the results.

    Philippe Schlenker

    2009-07-01

    Full Text Available The dynamic approach posits that a presupposition must be satisfied in its local context. But how is a local context derived from the global one? Extant dynamic analyses must specify in the lexical entry of any operator what its 'Context Change Potential' is, and for this very reason they fail to be sufficiently explanatory. To circumvent the problem, we revise two assumptions of the dynamic approach: we take the update process to be derivative from a classical, non-dynamic semantics -- which obviates the need for dynamic lexical entries; and we deny that a local context encodes what the speech act participants 'take for granted.' Instead, we take the local context of an expression E in a sentence S to be the smallest domain that one may restrict attention to when assessing E without jeopardizing the truth conditions of S. To match the results of dynamic semantics, local contexts must be computed incrementally, using only information about the expressions that precede E. This version of the theory can be shown to be nearly equivalent to the dynamic theory of Heim 1983 -- but unlike the latter, it is entirely predictive. We also suggest that local contexts can, at some cost, be computed symmetrically, taking into account information about all of S (except E; this leads to gradient predictions, whose assessment is left for future research. doi:10.3765/sp.2.3 BibTeX info

  7. Characteristics of the human host have little influence on which local Schistosoma mansoni populations are acquired.

    Directory of Open Access Journals (Sweden)

    Lúcio M Barbosa

    Full Text Available BACKGROUND: Brazil remains the country in the Americas with the highest prevalence of schistosomiasis. A combination of control efforts and development, however, has sharply reduced its intensity and distribution. The acquisition of specific schistosome populations may be dependent on host characteristics such as sex, age, geography, work, habits and culture. How these and other host characteristics align with parasite subpopulations may guide approaches to improve control. METHODOLOGY: A cohort of more than 90% of the residents in two rural communities in Brazil participated in an epidemiologic survey of demographic, socio-economic and behavioral characteristics. The variables sex, age, intensity of infection, socio-economic index, % lifetime spent on site, previous infection, and trips outside the district were used to group parasites infecting individuals. Schistosoma mansoni infection status was determined by examination of stools submitted on 3 different days. The aggregate of eggs collected from the whole stool was used to determine degree of population differentiation from allele frequencies for 15 microsatellites. CONCLUSIONS/SIGNIFICANCE: Infection prevalence was 41% for these communities, and the epidemiologic characteristics were similar to many of the endemic areas of Brazil and the world. Parasite population structuring was observed between the two communities (Jost's D 0.046, CI95% 0.042-0.051, although separated by only 8 km and connected by a highway. No structuring was observed when infected individuals were stratified by host's biologic, demographic or epidemiologic characteristics. Those most heavily infected best reflected the communities' overall parasite diversity. The lack of differentiation within villages suggests that individuals are likely to get infected at the same sites or that the same parasite multilocus genotypes can be found at most sites. The geographic structuring between villages and the lack of structuring by age of the host further supports the impression of a population little affected by migration or drift.

    Leukemia cells are superior to hematopoietic cells with a normal differentiation potential in buffering cellular stresses, but the underlying mechanisms for this leukemic advantage are not fully understood. Using CRISPR/Cas9 deletion of the canonical autophagy-essential gene Atg7, we found that erythroleukemia K562 cells are armed with two sets of autophagic machinery. Alternative mitophagy is functional regardless of whether the canonical autophagic mechanism is intact or disrupted. Although canonical autophagy defects attenuated cell cycling, proliferation and differentiation potential, the leukemia cells retained their abilities for mitochondrial clearance and for maintaining low levels of reactive oxygen species (ROS) and apoptosis. Treatment with a specific inducer of mitophagy revealed that the canonical autophagy-defective erythroleukemia cells preserved a mitophagic response. Selective induction of mitophagy was associated with the upregulation and localization of RAB9A on the mitochondrial membrane in both wild-type and Atg7(-/-) leukemia cells. When the leukemia cells were treated with the alternative autophagy inhibitor brefeldin A or when the RAB9A was knocked down, this mitophagy was prohibited. This was accompanied by elevated ROS levels and apoptosis as well as reduced DNA damage repair. Therefore, the results suggest that erythroleukemia K562 cells possess an ATG7-independent alternative mitophagic mechanism that functions even when the canonical autophagic process is impaired, thereby maintaining the ability to respond to stresses such as excessive ROS and DNA damage.

    2016-01-01

    Acquired factor VIII deficiency (acquired hemophilia A) is a rare condition characterized by the acquisition of autoantibodies that affect the clotting activity of factor VIII (fVIII). The most common manifestation in affected patients is a hemorrhagic diathesis. This disorder is associated with autoimmune diseases, pregnancy, postpartum period, drugs, and malignancy. Management of this condition begins with attempts to arrest an acute bleed based on the site and severity of bleeding and inhibitor titer. The next priority is eradication of the fVIII antibodies using immunosuppressive therapies. We report the case of a 66-year-old male who presented with spontaneous right thigh hematoma with prolonged activated partial prothrombin time and normal prothrombin time. Mixing studies confirmed the presence of an inhibitor. Further investigation for the underlying etiology of acquired hemophilia A leads to diagnosis of prostate cancer. Treatment consisted of bypassing agents including activated factor VII and activated prothrombin plasma concentrate to arrest the bleeding. Steroids and cyclophosphamide were added to suppress the fVIII inhibitors. Concomitant treatment of locally advanced prostate cancer with chemotherapy confirmed the eradication of the inhibitors. To our knowledge, this is the first reported case of prostate cancer diagnosed and treated simultaneously with acquired hemophilia A resulting in favorable patient outcome. PMID:27609734

    Full Text Available A locals collection is a set of parameters that are used to delimit data-mining operations. This piece uses a collection of locals from around Essex Massachusetts to shape and delimit an interrogation of post-reality in contemporary America. It explores the notion of crisis, the possibility of a crisis of empire that may or may not emerge in a media-space that does not allow crisis of empire to be mentioned and relations this maybe-crisis to the various levels of economic dysfunction that have become evident since late 2008. But mostly this piece explores ways in which particular stories about particular people do and do not link/link to these larger-scale narratives. This is the first of a potential series of locals collections that will mine the American post-real.

    We study products of precursors of spatially local operators, $W_{x_{n}}(t_{n}) ... W_{x_1}(t_1)$, where $W_x(t) = e^{-iHt} W_x e^{iHt}$. Using chaotic spin-chain numerics and gauge/gravity duality, we show that a single precursor fills a spatial region that grows linearly in $t$. In a lattice system, products of such operators can be represented using tensor networks. In gauge/gravity duality, they are related to Einstein-Rosen bridges supported by localized shock waves. We find a geometrical correspondence between these two descriptions, generalizing earlier work in the spatially homogeneous case.

    The adult classification of dysarthria correlating with the pathophysiology of the motor systems is usually applied to classify acquired childhood dysarthria. However, the validity of this adult model for children has not been studied systematically. All studies pertaining to analysis of speech features in acquired childhood dysarthria published since 1980 were reviewed. Studies were classified on the basis of neuroradiologic evidence of lesion site and associated motor disorder. This review demonstrates that knowledge of acquired childhood dysarthria is based on a limited number of single case studies, most of which pertain to dysarthria occurring after resection of cerebellar tumor. Definite similarities to adult dysarthria were not evident. Some similarity to acquired childhood dysarthria due to basal ganglia lesions was detected. We conclude that acquired childhood dysarthria requires its own classification.

    2017-01-20

    Acquired brain injury (ABI) can result in impairments in motor function, language, cognition, and sensory processing, and in emotional disturbances, which can severely reduce a survivor's quality of life. Music interventions have been used in rehabilitation to stimulate brain functions involved in movement, cognition, speech, emotions, and sensory perceptions. An update of the systematic review published in 2010 was needed to gauge the efficacy of music interventions in rehabilitation for people with ABI. To assess the effects of music interventions for functional outcomes in people with ABI. We expanded the criteria of our existing review to: 1) examine the efficacy of music interventions in addressing recovery in people with ABI including gait, upper extremity function, communication, mood and emotions, cognitive functioning, social skills, pain, behavioural outcomes, activities of daily living, and adverse events; 2) compare the efficacy of music interventions and standard care with a) standard care alone, b) standard care and placebo treatments, or c) standard care and other therapies; 3) compare the efficacy of different types of music interventions (music therapy delivered by trained music therapists versus music interventions delivered by other professionals). We searched the Cochrane Stroke Group Trials Register (January 2016), the Cochrane Central Register of Controlled Trials (CENTRAL) (2015, Issue 6), MEDLINE (1946 to June 2015), Embase (1980 to June 2015), CINAHL (1982 to June 2015), PsycINFO (1806 to June 2015), LILACS (1982 to January 2016), and AMED (1985 to June 2015). We handsearched music therapy journals and conference proceedings, searched dissertation and specialist music databases, trials and research registers, reference lists, and contacted relevant experts and music therapy associations to identify unpublished research. We imposed no language restriction. We performed the original search in 2009. We included all randomised controlled trials

    2015-05-01

    Full Text Available Introduction. Toxoplasma gondii is an intracellular protozoan that infects approximately one-third of the world’s population. Infection in human generally occurs through consuming food or drink contaminated with oocysts and tissue cysts from undercooked meat. Although latent infection with Toxoplasma gondii is among the most prevalent of human infections, it has been generally assumed that, except for congenital transmission, it is asymptomatic. Different conditions such as, number of parasite, virulence of the organism, genetic background, sex, and immunological status seem to affect the course of infection The demonstration that Toxoplasma infections can alter behavior, reproductive function in patients has led to a reconsideration of this assumption. During chronic acquired toxoplasmosis (САT identified the regularities of changes in the ratio of the immune system and the basal levels of sex hormones available informative methods, which made it possible to evaluate the severity of the flow chart and predict treatment outcome without resorting to complex research methods. Found that the host-parasite relationships and clinical manifestations of chronic toxoplasmosis depend largely on protective and adaptive responses and compensatory abilities of the human body. Material & methods. 112 patients attended in the 6 Department of Kharkiv Regional Infectious Diseases Hospital №22 (Department of Medical Parasitology and Tropical Diseases of Kharkiv Medical Academy of Postgraduate Education, in Kharkiv, Ukraine were enrolled in the study. Forty four patients (39,3±4,6% were male and sixty eight (60,7±4,6% were female. The age of the patients was 18 till 72 years. Results & discussion. All of 112 CAT patients had subjective clinical symptoms in various combinations: increased fatigue 99,1 ± 0,9%, headache and tiredness 95,5 ± 1,9%, pain in the liver 88,4 ± 3,1%, bitter taste in the mouth 93,8 ± 2,2%, muscle pain 81,3 ± 3,7% and joint pain

    Full Text Available Urinary tract infections are among the most common human infections. They may be community-acquired or nosocomial, and caused by a variety of microorganisms. In the present study, we analysed more than 4000 urine samples collected from in-patients and outpatients, and registered the differences in the etiological spectrum of agents. The most widespread uropathogens are gram-negative rods, from them E. coli, Klebsiella spp. and the non-fermentive genus Pseudomonas. Women are more intensively affected by E. coli. From gram-positive cocci, the leading agents are coagulase negative Staphylococci, followed by S. aureus. No differences were registered between the genders. Polyresistance among gram-negative uropathogens is high.

    Aponeurotic defects and disinsertion of the levator aponeurosis are responsible for many cases of acquired ptosis. The typical clinical findings in aponeurotic defects are: history of prior orbital swelling, injury, ocular surgery, blepharochalasis; good to excellent levator function, thinning of the eyelid above the tarsus, high to absent lid crease, and normal Müller's muscle function. The purpose of the treatment is to repair a defect or advance the aponeurosis onto the tarsus. Levator aponeurosis surgery was used to treat 18 upper eyelids with acquired ptosis. Local anesthesia and surgery from an anterior approach were used in all cases. The advantages of this technique are: The lid height is determined by asking the patient to look in various fields of gaze. A blepharoplasty can be performed when necessary. The lid crease is formed. The exposition of the levator aponeurosis disinsertion is easier to recognize.

    2014-01-01

    Full Text Available Photodynamic therapy (PDT has been used for treatment of various intraocular tumors including choroidal hemangioma, vasoproliferative tumor, amelanotic choroidal melanoma and choroidal neovascular membrane due to choroidal osteoma. This case report documents the effect of PDT for a presumed acquired retinal astrocytoma. A 42-year-old female with a juxtapapillary acquired astrocytoma was treated with a single session of PDT using standard parameters. The tumor showed dramatic regression over 6 months into a fibrotic scar. It remained regressed and stable with 20/20 vision after 51 months of follow-up. We believe that PDT can be used as a primary treatment for acquired retinal astrocytoma.

    1982-06-01

    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.

    The semantics of concurrent data structures is usually given by a sequential specification and a consistency condition. Linearizability is the most popular consistency condition due to its simplicity and general applicability. Nevertheless, for applications that do not require all guarantees offered by linearizability, recent research has focused on improving performance and scalability of concurrent data structures by relaxing their semantics. In this paper, we present local linearizability,...

    2017-05-01

    This study aimed to describe the burden of community-acquired acute kidney injury (AKI) in China based on a nationwide survey about AKI. Cross-sectional and retrospective study. A national sample of 2,223,230 hospitalized adult patients from 44 academic/local hospitals in Mainland China was used. AKI was defined according to the 2012 KDIGO AKI creatinine criteria or an increase or decrease in serum creatinine level of 50% during the hospital stay. Community-acquired AKI was identified when a patient had AKI that could be defined at hospital admission. The rate, cause, recognition, and treatment of community-acquired AKI were stratified according to hospital type, latitude, and economic development of the regions in which the patients were admitted. All-cause in-hospital mortality and recovery of kidney function at hospital discharge. 4,136 patients with community-acquired AKI were identified during the 2 single-month snapshots (January 2013 and July 2013). Of these, 2,020 (48.8%) had cases related to decreased kidney perfusion; 1,111 (26.9%), to intrinsic kidney disease; and 499 (12.1%), to urinary tract obstruction. In the north versus the south, more patients were exposed to nephrotoxins or had urinary tract obstructions. 536 (13.0%) patients with community-acquired AKI had indications for renal replacement therapy (RRT), but only 347 (64.7%) of them received RRT. Rates of timely diagnosis and appropriate use of RRT were higher in regions with higher per capita gross domestic product. All-cause in-hospital mortality was 7.3% (295 of 4,068). Delayed AKI recognition and being located in northern China were independent risk factors for in-hospital mortality, and referral to nephrology providers was an independent protective factor. Possible misclassification of AKI and community-acquired AKI due to nonstandard definitions and missing data for serum creatinine. The features of community-acquired AKI varied substantially in different regions of China and were closely

    Acquired hemophilia A is a rare bleeding disorder caused by autoantibodies to coagulation FVIII. Bleeding episodes at presentation are spontaneous and severe in most cases. Optimal hemostatic therapy is controversial, and available data are from observational and retrospective studies only. The EACH2 registry, a multicenter, pan-European, Web-based database, reports current patient management. The aim was to assess the control of first bleeding episodes treated with a bypassing agent (rFVIIa or aPCC), FVIII, or DDAVP among 501 registered patients. Of 482 patients with one or more bleeding episodes, 144 (30%) received no treatment for bleeding; 31 were treated with symptomatic therapy only. Among 307 patients treated with a first-line hemostatic agent, 174 (56.7%) received rFVIIa, 63 (20.5%) aPCC, 56 (18.2%) FVIII, and 14 (4.6%) DDAVP. Bleeding was controlled in 269 of 338 (79.6%) patients treated with a first-line hemostatic agent or ancillary therapy alone. Propensity score matching was applied to allow unbiased comparison between treatment groups. Bleeding control was significantly higher in patients treated with bypassing agents versus FVIII/DDAVP (93.3% vs 68.3%; P = .003). Bleeding control was similar between rFVIIa and aPCC (93.0%; P = 1). Thrombotic events were reported in 3.6% of treated patients with a similar incidence between rFVIIa (2.9%) and aPCC (4.8%).

    2012-07-05

    Acquired hemophilia A (AHA) is an autoimmune disease caused by an autoantibody to factor VIII. Patients are at risk of severe and fatal hemorrhage until the inhibitor is eradicated, and guidelines recommend immunosuppression as soon as the diagnosis has been made. The optimal immunosuppressive regimen is unclear; therefore, data from 331 patients entered into the prospective EACH2 registry were analyzed. Steroids combined with cyclophosphamide resulted in more stable complete remission (70%), defined as inhibitor undetectable, factor VIII more than 70 IU/dL and immunosuppression stopped, than steroids alone (48%) or rituximab-based regimens (59%). Propensity score-matched analysis controlling for age, sex, factor VIII level, inhibitor titer, and underlying etiology confirmed that stable remission was more likely with steroids and cyclophosphamide than steroids alone (odds ratio = 3.25; 95% CI, 1.51-6.96; P < .003). The median time to complete remission was approximately 5 weeks for steroids with or without cyclophosphamide; rituximab-based regimens required approximately twice as long. Immunoglobulin administration did not improve outcome. Second-line therapy was successful in approximately 60% of cases that failed first-line therapy. Outcome was not affected by the choice of first-line therapy. The likelihood of achieving stable remission was not affected by underlying etiology but was influenced by the presenting inhibitor titer and FVIII level.

    Sutherland, Shelbie L; Friedman, Ori

    2012-01-01

    Children acquire general knowledge about many kinds of things, but there are few known means by which this knowledge is acquired. In this article, it is proposed that children acquire generic knowledge by sharing in pretend play. In Experiment 1, twenty-two 3- to 4-year-olds watched pretense in which a puppet represented a "nerp" (an unfamiliar kind of animal). For instance, in one scenario, the nerp ate and disliked a carrot. When subsequently asked generic questions about real nerps, children's responses suggested that they had learned general facts (e.g., nerps dislike carrots). In Experiment 2, thirty-two 4- to 5-year-olds learned from scenarios lacking pretend speech or sound effects. The findings reveal a long overlooked means by which children can acquire generic knowledge.

    Zika virus is an emerging mosquito-borne flavivirus that typically causes an asymptomatic infection or mild illness, although infection during pregnancy is a cause of microcephaly and other serious brain abnormalities. Guillain-Barré syndrome and other neurologic complications can occur in adults after Zika virus infection. However, there are few published reports describing postnatally acquired Zika virus disease among children. During January 2015-July 2016, a total of 158 cases of confirmed or probable postnatally acquired Zika virus disease among children aged Zika virus disease in children who have an epidemiologic risk factor and clinically compatible illness, and should report cases to their state or local health department.

These included 78 patients with pulmonary tuberculosis and 81 with community-acquired p neumonia. The clinical features of infiltrative pulmonary tuberculosis (n = 48) and mild community-acquired pneumonia (n = 51) were compared. The course of caseous pneumonia (n = 30) was compared with that of moderate and severe community-acquired pneumonia (n = 30). Significant differences in the manifestations of the intoxication and bronchopulmonary syndrome were not found in patients with community-acquired pneumonia and infiltrative pulmonary tuberculosis. Physical studies showed that in patients with community-acquired pneumonia, moist rale (54.9%) and crepitation (11.8%) were prevalent, but in those with infiltrative tuberculosis rale was absent in 60.4% of cases and the pattern of respiration was unchanged in 79.2%. Chest X-ray studies indicated that in patients with community-acquired pneumonia, lower lobar inflammatory changes were predominant in 62.8% of cases whereas in those with infiltrative pulmonary tuberculosis the process was mainly bilateral (43.8%) with the presence of destructive changes (83.3%) and bronchogenic dissemination (66.7%). In patients with caseous pneumonia, the intoxication syndrome was more significant than in those with severe community-acquired pneumonia. Chest X-ray studies demonstrated that in patients with caseous pneumonia, specific changes were bilateral with the involvement of 2 lobes or more, with destruction and bronchogenic dissemination while in those with community-acquired pneumonia, the pulmonary processes were predominantly bilateral (76.6%) at the lower lobar site (36.7%).

    Full Text Available Lipodystrophy is a group of metabolic disorders, possibly caused by autoimmune disease. In this report, we describe a case of adult-onset acquired partial lipodystrophy accompanied by rheumatoid arthritis without a family history. Interestingly, immunohistochemical staining revealed dense infiltration of IL-27-producing cells as well as MMP-7- and MMP-28-expressing cells, both of which have been reported to facilitate the development of autoimmune disease. Our present case might suggest possible mechanisms for acquired partial lipodystrophy.

    Full Text Available Rhinoplasty is a plastic surgery procedure to reconstruct the nose. Silicone alloplastic materials are most widely used as implants for rhinoplasty, but calcification on the surface occurs with long-term usage. Herein, we report a case of gruel-like calcification approximately 50 years after silicone implant rhinoplasty. In this case, calcification on the silicone surface might have transformed into gruel-like deposits, which presented as a subcutaneous mass at the dorsal area of the nose. The precise mechanism is unclear; a pH change in the tissue might have occurred during the process of inflammation, leading to the dissolution of calcified deposits.

    Full Text Available The study is dedicated to identify the main factors determining the propensity of local authorities to compete for the access to the limited as well as mobile sources of local tax revenue. The success of such an activity should be discussed in relation to the stabilization of local budget revenues; hence it seems that the barriers of leaving tax jurisdiction could be better index to evaluate of the efficiency of local tax policy. The theoretical approach is based on the assumption that, if central government provides limitations of the right to improve local tax policy means (the scope of local tax jurisdiction, the local governments should focus on both the efficient acquiring the sources of tax revenues, and the stabilization of tax revenues in the future, in particular by the implementation of the barriers of leaving tax jurisdiction. The paper suggests studying a propensity to tax competition. The article formulates desideratum of the efficiency of spending on acquiring the sources of tax revenue, in particular, the need to identify the barriers to leave tax jurisdiction is suggested. The first and foremost way to build the barrier to leave tax jurisdiction could be reducing tax liabilities by local tax authorities, in particular by introducing local tax reliefs and local tax exemptions, as well as lowering local tax rates. Hence, the model of local authorities’ competition for local tax resources could be proposed. The empirical studies are dedicated to identify the actual propensity of Polish local government to execute the legal ability to impose tax policy instruments. The inquiry is based on comparing the fiscal consequences of implementing local tax policy within two groups of local authorities: small towns and countries (gminas and medium-size towns and big cities (cities with powiat status. The period under investigation contains 14 fiscal years, started 2000 and finished in 2013. The method is based on the analysis of the

  5. Serotonergic hyperactivity as a potential factor in developmental, acquired and drug-induced synesthesia.

    2013-01-01

    Though synesthesia research has seen a huge growth in recent decades, and tremendous progress has been made in terms of understanding the mechanism and cause of synesthesia, we are still left mostly in the dark when it comes to the mechanistic commonalities (if any) among developmental, acquired and drug-induced synesthesia. We know that many forms of synesthesia involve aberrant structural or functional brain connectivity. Proposed mechanisms include direct projection and disinhibited feedback mechanisms, in which information from two otherwise structurally or functionally separate brain regions mix. We also know that synesthesia sometimes runs in families. However, it is unclear what causes its onset. Studies of psychedelic drugs, such as psilocybin, LSD and mescaline, reveal that exposure to these drugs can induce synesthesia. One neurotransmitter suspected to be central to the perceptual changes is serotonin. Excessive serotonin in the brain may cause many of the characteristics of psychedelic intoxication. Excessive serotonin levels may also play a role in synesthesia acquired after brain injury. In brain injury sudden cell death floods local brain regions with serotonin and glutamate. This neurotransmitter flooding could perhaps result in unusual feature binding. Finally, developmental synesthesia that occurs in individuals with autism may be a result of alterations in the serotonergic system, leading to a blockage of regular gating mechanisms. I conclude on these grounds that one commonality among at least some cases of acquired, developmental and drug-induced synesthesia may be the presence of excessive levels of serotonin, which increases the excitability and connectedness of sensory brain regions.

    We report the case of an individual with acquired prosopagnosia who experiences extreme difficulties in recognizing familiar faces in everyday life despite excellent object recognition skills. Formal testing indicates that he is also severely impaired at remembering pre-experimentally unfamiliar faces and that he takes an extremely long time to identify famous faces and to match unfamiliar faces. Nevertheless, he performs as accurately and quickly as controls at identifying inverted familiar and unfamiliar faces and can recognize famous faces from their external features. He also performs as accurately as controls at recognizing famous faces when fracturing conceals the configural information in the face. He shows evidence of impaired global processing but normal local processing of Navon figures. This case appears to reflect the clearest example yet of an acquired prosopagnosic patient whose familiar face recognition deficit is caused by a severe configural processing deficit in the absence of any problems in featural processing. These preserved featural skills together with apparently intact visual imagery for faces allow him to identify a surprisingly large number of famous faces when unlimited time is available. The theoretical implications of this pattern of performance for understanding the nature of acquired prosopagnosia are discussed.

    Previous studies report that acquired prosopagnosia is frequently associated with topographic disorientation. Whether this is associated with a specific anatomic subtype of prosopagnosia, how frequently it is seen with the developmental variant, and what specific topographic function is impaired to account for this problem are not known. We studied ten subjects with acquired prosopagnosia from either occipitotemporal or anterior temporal (AT) lesions and seven with developmental prosopagnosia. Subjects were given a battery of topographic tests, including house and scene recognition, the road map test, a test of cognitive map formation, and a standardized self-report questionnaire. House and/or scene recognition were frequently impaired after either occipitotemporal or AT lesions in acquired prosopagnosia. Subjects with occipitotemporal lesions were also impaired in cognitive map formation: an overlap analysis identified right fusiform and parahippocampal gyri as a likely correlate. Only one subject with acquired prosopagnosia had mild difficulty with directional orientation on the road map test. Only one subject with developmental prosopagnosia had difficulty with cognitive map formation, and none were impaired on the other tests. Scores for house and scene recognition correlated most strongly with the results of the questionnaire. We conclude that topographic disorientation in acquired prosopagnosia reflects impaired place recognition, with a contribution from poor cognitive map formation when there is occipitotemporal damage. Topographic impairments are less frequent in developmental prosopagnosia.

    Full Text Available Hypoparathyroidism is a disorder of calcium and phosphorus metabolism due to decreased secretion of parathyroid hormone. Hypoparathyroidism can be hereditary and acquired. Acquired hypoparathyroidism usually occurs following neck surgery (thyroid surgery or parathyroid surgery. Along with systemic manifestations, hypoparathyroidism produces some skin manifestations. Lack of study regarding mucocutaneous manifestations of acquired hypoparathyroidism prompted us to undertake this study. To evaluate the mucocutaneous manifestations of acquired hypoparathyroidism. An observational study done in a tertiary care hospital of Kolkata by comprehensive history taking, through clinical examination and relevant laboratory investigations. Twenty-one patients were included in the study. The commonest form of acquired hypoparathyroidism was neck surgery (thyroidectomy and parathyroidectomy operation. Mucocutaneous manifestations were present in 76.19% of patients. The most frequent mucocutaneous manifestation was found in the hairs like the loss of axillary hair (61.9%, loss of pubic hair (52.38%, coarsening of body hair (47.62%, and alopecia areata (9.52%. The nail changes noted were brittle and ridged nail, followed by onycholysis, onychosezia, and onychomedesis. The most common skin features were xerotic skin in 11 patients (52.38%, followed by pellagra-like skin pigmentation, pustular psoriasis and acne form eruption, bullous impetigo, etc. Mucosa was normal in all the cases excepting the one which showed oral candidiasis.

    2014-01-01

    Acquired dyslexia offers a unique window on to the nature of the cognitive and neural architecture supporting skilled reading. This paper provides an integrative overview of recent empirical and computational work on acquired dyslexia within the context of the primary systems framework as implemented in connectionist neuropsychological models. This view proposes that damage to general visual, phonological or semantic processing abilities are the root causes of different forms of acquired dyslexia. Recent case-series behavioural evidence concerning pure alexia, phonological dyslexia and surface dyslexia that supports this perspective is presented. Lesion simulations of these findings within connectionist models of reading demonstrate the viability of this approach. The commitment of such models to learnt representations allows them to capture key aspects of performance in each type of acquired dyslexia, particularly the associated non-reading deficits, the role of relearning and the influence of individual differences in the premorbid state of the reading system. Identification of these factors not only advances our understanding of acquired dyslexia and the mechanisms of normal reading but they are also relevant to the complex interactions underpinning developmental reading disorders.

  13. Acquired and Participatory Competencies in Health Professions Education: Definition and Assessment in Global Health.

    Science.gov (United States)

    Eichbaum, Quentin

    2016-09-06

    Many health professions education programs in high-income countries (HICs) have adopted a competency-based approach to learning. Although global health programs have followed this trend, defining and assessing competencies has proven problematic, particularly in resource-constrained settings of low- and middle-income countries (LMICs) where HIC students and trainees perform elective work. In part, this is due to programs failing to take sufficient account of local learning, cultural, and health contexts.A major divide between HIC and LMIC settings is that the learning contexts of HICs are predominantly individualist, whereas those of LMICs are generally collectivist. Individualist cultures view learning as something that the individual acquires independent of context and can possess; collectivist cultures view learning as arising dynamically from specific contexts through group participation.To bridge the individualist-collectivist learning divide, the author proposes that competencies be classified as either acquired or participatory. Acquired competencies can be transferred across contexts and assessed using traditional psychometric approaches; participatory competencies are linked to contexts and require alternative assessment approaches. The author proposes assessing participatory competencies through the approach of self-directed assessment seeking, which includes multiple members of the health care team as assessors.The proposed classification of competencies as acquired or participatory may apply across health professions. The author suggests advancing participatory competencies through mental models of sharing. In global health education, the author recommends developing three new competency domains rooted in participatory learning, collectivism, and sharing: resourceful learning; transprofessionalism and transformative learning; and social justice and health equity.

  14. Hospital-acquired infections - when are hospitals legally liable?

    Science.gov (United States)

    McQuoid-Mason, David

    2012-04-12

    Hospital-acquired infections (nosocomial infections) are acquired in healthcare settings by patients admitted for reasons unrelated to the infection or not previously infected when admitted to the facility. Liability for hospital-acquired infections depends on whether the hospital: (i) has introduced best practice infection control measures; (ii) has implemented best practice infection control measures; or (iii) will be vicariously liable for negligent or intentional failures by staff to comply with the infection control measures implemented. A hospital and hospital administrators may be held directly liable for not introducing or implementing best practice infection control measures, resulting in harm to patients. The hospital may also be held vicariously liable where patients have been harmed because hospital staff negligently or intentionally failed to comply with the infection control measures that have been implemented by the hospital, during the course and scope of their employment.

    2014-01-01

    (V600)BRAF mutation was identified as an ideal target for clinical therapy due to its indispensable roles in supporting melanoma initiation and progression. Despite the fact that BRAF inhibitors (BRAFi) can elicit anti-tumor responses in the majority of treated patients and confer overall survival benefits, acquired drug resistance is a formidable obstacle to long-term management of the disease. Several aberrant events including RTK upregulation, NRAS mutation, mutant BRAF amplification or alternative splicing, and MEK mutation have been reported as acquired BRAFi resistance mechanisms. Clinially, detection of these resistance mechanisms help understand drug response patterns and help guide combinatorial therapeutic strategies. Therefore, quick and accurate diagnosis of the resistant mechanisms in tumor biopsies has become an important starting point for personalized therapy. In this chapter, we review the major acquired BRAFi resistance mechanisms, highlight their therapeutic implications, and provide the diagnostic methods from clinical samples.

    2014-04-01

    Individuals with acquired physical disabilities report lower levels of athletic identity. The objective of this study was to further explore why athletic identity may be lost or (re)developed after acquiring a physical disability. Seven women and four men (range = 28-60 years) participated in approximately 1-hour-long semistructured interviews; data were subjected to a narrative analysis. The structural analysis revealed three narrative types. The nonathlete narrative described physical changes in the body as reasons for diminished athletic identity. The athlete as a future self primarily focused on present sport behavior and performance goals such that behavior changes diminished athletic identity. The present self as athlete narrative type focused on the aspects of their present sport involvement, such as feedback from other athletes and skill development, which supported their athletic identity. Implications of these narrative types with respect to sport promotion among people with acquired physical disabilities are discussed.

    The initial antibiotic therapy of community-acquired pneumonia is carried out empirically. In the treatment of severe community-acquired pneumonia in children from 2 months to 5 years, the drug of choice is amoxicillin orally. Macrolides are the drugs of choice for children aged 5 to 16 years. In severe pneumonia, drugs of choice are amoxicillin clavulanate, 2nd–4th generation cephalosporins. In general, the duration of antibiotic therapy in the community-acquired pneumonia caused by typical bacteria is 7–10 days, by atypical bacteria — 10–14 days. In the real clinical practice, the errors associated with the choice of drug, route of administration, dosage, regimen of application, length of treatment are frequent during antibacterial therapy.

It is well-known when and why the disabilities occurr at acquired aphasia or disphasia.The child with acquired aphasia or disphasia has early brain impairements and a relative improvement happens with adequate treatment and prompt rehabilitation treatment. It is more obvious with children than with adults.This fast and complete rehabilitation happens due to the plastic character of child’s brain and the possibilities for intro-hemisphere and inter-hemisphere reorganization of speech functions in childhood.

  19. Local Warming

    2012-01-01

    Using 55 years of daily average temperatures from a local weather station, I made a least-absolute-deviations (LAD) regression model that accounts for three effects: seasonal variations, the 11-year solar cycle, and a linear trend. The model was formulated as a linear programming problem and solved using widely available optimization software. The solution indicates that temperatures have gone up by about 2 degrees Fahrenheit over the 55 years covered by the data. It also correctly identifies the known phase of the solar cycle; i.e., the date of the last solar minimum. It turns out that the maximum slope of the solar cycle sinusoid in the regression model is about the same size as the slope produced by the linear trend. The fact that the solar cycle was correctly extracted by the model is a strong indicator that effects of this size, in particular the slope of the linear trend, can be accurately determined from the 55 years of data analyzed. The main purpose for doing this analysis is to demonstrate that it i...

    In 1991, in the northern region of Ghana, during the cholera epidemic, 10 rural health centers replied to a questionnaire regarding cholera case referrals. The results were as follows: 6 centers referred serious cases to hospitals, 2 did not receive patients because of fear of infection, and 2 received all patients. Although no patients admitted to the rural health centers died, many of the referred patients did. Of 14 cases referred to a hospital, 3 died in transit, 4 died at the hospital, and 7 survived. Deaths might be prevented if patients were treated promptly and locally with oral rehydration solutions based on cereals and rice; these are easy to prepare, superior to, and more available than standard oral rehydration salts (ORS). One mother walked 5 miles to a rural health post with her sick baby on her back, only to find that the dehydrated child had died on the way. During the 1991 cholera epidemic in Ghana, the author treated several patients in their homes; all recovered. Prompt and frequent rehydration in the home is the best treatment for diarrhea and cholera.

  1. The PHA test reflects acquired T-cell mediated immunocompetence in birds.

    Directory of Open Access Journals (Sweden)

    José L Tella

    Full Text Available BACKGROUND: cological immunology requires techniques to reliably measure immunocompetence in wild vertebrates. The PHA-skin test, involving subcutaneous injection of a mitogen (phytohemagglutinin, PHA and measurement of subsequent swelling as a surrogate of T-cell mediated immunocompetence, has been the test of choice due to its practicality and ease of use in the field. However, mechanisms involved in local immunological and inflammatory processes provoked by PHA are poorly known, and its use and interpretation as an acquired immune response is currently debated. METHODOLOGY: Here, we present experimental work using a variety of parrot species, to ascertain whether PHA exposure produces larger secondary than primary responses as expected if the test reflects acquired immunocompetence. Moreover, we simultaneously quantified T-lymphocyte subsets (CD4(+, CD5(+ and CD8(+ and plasma proteins circulating in the bloodstream, potentially involved in the immunological and inflammatory processes, through flow cytometry and electrophoresis. PRINCIPAL FINDINGS: Our results showed stronger responses after a second PHA injection, independent of species, time elapsed and changes in body mass of birds between first and second injections, thus supporting the adaptive nature of this immune response. Furthermore, the concomitant changes in the plasma concentrations of T-lymphocyte subsets and globulins indicate a causal link between the activation of the T-cell mediated immune system and local tissue swelling. CONCLUSIONS/SIGNIFICANCE: These findings justify the widespread use of the PHA-skin test as a reliable evaluator of acquired T-cell mediated immunocompetence in diverse biological disciplines. Further experimental research should be aimed at evaluating the relative role of innate immunocompetence in wild conditions, where the access to dietary proteins varies more than in captivity, and to ascertain how PHA responses relate to particular host

    Shading acquired materials with high-frequency illumination is computationally expensive. Estimating the shading integral requires multiple samples of the incident illumination. The number of samples required may vary across the image, and the image itself may have high- and low-frequency variations, depending on a combination of several factors. Adaptively distributing computational budget across the pixels for shading is a challenging problem. In this paper, we depict complex materials such as acquired reflectances, interactively, without any precomputation based on geometry. In each frame, we first estimate the frequencies in the local light field arriving at each pixel, as well as the variance of the shading integrand. Our frequency analysis accounts for combinations of a variety of factors: the reflectance of the object projecting to the pixel, the nature of the illumination, the local geometry and the camera position relative to the geometry and lighting. We then exploit this frequency information (bandwidth and variance) to adaptively sample for reconstruction and integration. For example, fewer pixels per unit area are shaded for pixels projecting onto diffuse objects, and fewer samples are used for integrating illumination incident on specular objects.

    Mycosis fungoides is the most common subtype of primary cutaneous lymphoma and has several clinical variants. We report a 74-year-old man presenting with an acquired palmoplantar keratoderma initially diagnosed and treated as psoriasis with suboptimal improvement. Several months later the patient developed patches and plaques that were histologically consistent with mycosis fungoides. These lesions were ameliorated with the treatment of the underlying mycosis fungoides and the palmoplantar keratoderma resolved promptly with radiotherapy. This case highlights the importance of considering mycosis fungoides as an infrequent but serious cause of acquired palmoplantar keratoderma.

    Background: Epidermoid and dermoid cyst comprise <1% of spinal tumors and may be congenital (hamartoma) or acquired (iatrogenic) in origin. Epidermoid cysts within the neuraxis are rare benign neoplasms that are most commonly located in the intracranial region. Case Description: Here, we report the a case of an acquired intradural extramedullary epidermoid cyst involving the thoracic region in an adult female who had no associated history of an accompanying congenital spinal deformity. Conclusion: Early diagnosis and immediate surgical intervention reduce patient morbidity. Near complete or subtotal excision of the cyst wall is warranted to prevent inadvertent injury to the spinal cord thus minimizing neurological morbidity. PMID:26904369

    A patient with systemic lupus erythematosus (SLE) developed acquired hemophilia A. The patient, a 24-year-old Japanese woman, was referred to our hospital because of uncontrollable bleeding following a tooth extraction. Laboratory examination revealed prolonged APTT (116 seconds), reduced factor VIII activity (2.8 %) and the presence of factor VIII inhibitor at a titer of 46.5 Bethesda units/ml. Transfusion of prothrombin complex concentrate and activated prothrombin complex concentrate followed by administration of prednisolone and cyclophosphamide successfully arrested bleeding and reduced the factor VIII inhibitor level. Acquired hemophilia A is a rare but lethal condition. Rapid diagnosis and introduction of adequate therapies are critical.

    Pediatric spine pathology poses a diagnostic challenge for radiologists. Acquired spine pathology often yields nonspecific signs and symptoms in children, especially in the younger age groups, and diagnostic delay can carry significant morbidity. This review is focused on some of the more common diagnostic dilemmas we face when attempting to evaluate and diagnose acquired pediatric spine anomalies in daily practice. An understanding of some of the key differentiating features of these disease processes in conjunction with pertinent history, physical exam, and advanced imaging techniques can indicate the correct diagnosis.

    Coronary-cameral fistulas are usually congenital, rarely acquired; the complication of this anomaly with ventricular pseudoaneurysm is exceptional. We report a new case of acquired coronary-cameral fistula, occurred in a patient who had received a bypass graft and who had suffered from angina 1 year after the surgery. On computed tomography coronary angiography, the fistula seems to communicate the first diagonal to a left ventricle pseudoaneurysm. Embolization of the fistula and filling of the pseudoaneurysm by neurocoil were successfully performed. The clinical and angiographic control after 3 months showed symptoms improvement and absence of recanalization of the fistula.

    This study aims to determine the environmental factors nurses identify as being irritating to people with acquired brain injury. This was a qualitative study. An experienced interviewer used the Critical Decision Method to interview 28 nurses working in 10 inpatient brain injury rehabilitation units in Australia on a one to one basis for 1-1.5 h on two consecutive days. Transcripts of interviews were analysed using thematic analysis. Nurses identified five groups of irritants that acted as triggers for aggression: The nurses in this study identified many environmental factors that irritate people with acquired brain injury. Some irritants appeared unavoidable but others could be addressed by staff expertise.

    2002-01-01

    Full Text Available Bronchial webs are thin, membrane-like diaphragms that may obstruct the airway. Several congenital cases have been reported. Though rare, the true incidence of these lesions is probably underestimated because many of them are unrecognized. The case of a 71-year-old woman with an acquired bronchial web causing right main stem bronchus obstruction that went unrecognized for 47 years post-trauma is reported. The lesion was successfully treated using rigid bronchoscopy with laser therapy, balloon dilation and stent placement. This is the first reported case of an acquired bronchial web formation. It is also the first reported case that was successfully treated with this technique.

    Hand hygiene is important to prevent hospital-acquired infections. Patients' hand hygiene is just as important as hospital workers' hand hygiene. Hospital-acquired infection rates remain a concern across health centers. To improve patients' hand hygiene through the promotion and use of hand washing with soap and water, hand sanitizer, or both and improve patients' education to reduce hospital-acquired infections. In August 2013, patients in a cardiothoracic postsurgical step-down unit were provided with individual bottles of hand sanitizer. Nurses and nursing technicians provided hand hygiene education to each patient. Patients completed a 6-question survey before the intervention, at hospital discharge and 1, 2, and 3 months after the intervention. Hospital-acquired infection data were tracked monthly by infection prevention staff. Significant correlations were found between hand hygiene and rates of infection with vancomycin-resistant enterococci (P = .003) and methicillin-resistant Staphylococcus aureus (P = .01) after the intervention. After the implementation of hand hygiene interventions, rates of both infections declined significantly and patients reported more staff offering opportunities for and encouraging hand hygiene. This quality improvement project demonstrates that increased hand hygiene compliance by patients can influence infection rates in an adult cardiothoracic step-down unit. The decreased infection rates and increased compliance with hand hygiene among the patients may be attributed to the implementation of patient education and the increased accessibility and use of hand sanitizer. ©2017 American Association of Critical-Care Nurses.

  5. Acquired Fanconi syndrome in four cats treated with chlorambucil.

    Reinert, Natalie C; Feldman, David G

    2016-12-01

    Fanconi syndrome (FS) is well described in humans and dogs, but has not been reported in cats. This case series describes four cats with acquired FS. On the basis of clinical signs and intestinal biopsies, all cats were initially diagnosed with alimentary lymphoma or inflammatory bowel disease. Treatment with chlorambucil and corticosteroids was started at standard doses, based on published protocols. Within 2-26 months of the start of treatment, glucosuria, despite normoglycemia, was identified incidentally on routine biochemical screening; FS was diagnosed with urine metabolic assays, confirming aminoaciduria and glucosuria in all four cases. Neither polyuria nor polydipsia were noted in any case, and only 1/4 cats had any clinical signs at the time of diagnosis. Partial or complete resolution of FS was seen in 3/4 cases within 3 months of discontinuing chlorambucil therapy. This is the first case series to document acquired FS in the cat, and the first to suggest a possible association between chlorambucil and acquired FS. Cats treated with chlorambucil should be monitored for the development of glucosuria, and discontinuation of chlorambucil should be considered if FS is identified. Further study into the association between chlorambucil and acquired FS in cats is warranted. © The Author(s) 2015.

    Corticosteroid therapy as adjunctive treatment in community-acquired pneumonia (CAP) is a promising but controversial subject. The potentially beneficial effect of corticosteroids is based on the ability of steroids to dampen an excessive inflammatory response that often occurs in patients with CAP. This excessive inflammatory response can cause damage to the lungs and other organs, and is associated with poor outcome.

    Full Text Available Objective. We present the case of a 73-year-old female, with no family or personal history of a bleeding disorder, who had a classic presentation for acquired hemophilia A. Factor VIII activity was low but detectable and a factor VIII inhibitor was undetectable. Methods. The patient’s plasma was comprehensively studied to determine the cause of the acquired coagulopathy. Using the Nijmegen modification of the Bethesda assay, no factor VIII autoantibody was measureable despite varying the incubation time from 1 to 3 hours. Results. The aPTT was prolonged at 46.8 seconds, which did not correct in the 4 : 1 mix but did with 1 : 1 mix. Using a one stage factor VIII activity assay, the FVIII activity was 16% and chromogenic FVIII activity was also 16%. The patient was treated with recombinant FVII and transfusion, significantly reducing bleeding. Long-term therapy was initiated with cyclophosphamide and prednisone with normalization of FVIII activity. Conclusions. Physicians can be presented with the challenging clinical picture of an acquired factor VIII inhibitor without a detectable inhibitor by the Bethesda assay. Standard therapy for an acquired hemophilia A should be considered.

    We investigated the positivity rate, the detection rates for non-covered pathogens and the therapeutic impact of microbiological samples (MS) in community-acquired pneumonia (CAP), nursing home-acquired pneumonia (NHAP) and hospital-acquired pneumonia (HAP) in elderly hospitalised patients. Patients aged 75 years and over with pneumonia and hospitalised between 1/1/2013 and 30/6/2013 in the departments of medicine (5) and intensive care (1) of our university hospital were included. Microbiological findings, intra-hospital mortality and one-year mortality were recorded. Among the 217 patients included, there were 138 CAP, 56 NHAP and 23 HAP. MS were performed in 89.9, 91.1 and 95.6 % of CAP, NHAP and HAP, respectively. Microbiological diagnosis was made for 29, 11.8 and 27.3 % of patients for CAP, NHAP and HAP, respectively (p = 0.05). Non-covered pathogens were detected for 8 % of CAP, 2 % of NHAP and 13.6 % of HAP (p = 0.1). The antimicrobial spectrum was significantly more frequently reduced when the MS were positive (46.7 % vs. 10.8 % when MS were negative, p = 10(-7)). The MS positivity rate was significantly lower in NHAP than in CAP and HAP. MS revealed non-covered pathogens in only 2 % of NHAP. These results show the poor efficiency and weak clinical impact of MS in the management of pneumonia in hospitalised older patients and suggest that their use should be rationalised.

    A consistent theory of massive gravity, where the graviton acquires mass by spontaneously breaking diffeomorphism invariance, is now well established. We supersymmetrize this construction using N =1 fields. Coupling to N = 1 supergravity is done by applying the rules of tensor calculus to construct an action invariant under local N = 1 supersymmetry. The supersymmetric action is shown, at the quadratic level, to be free of ghosts and have as its spectrum a massive graviton, two gravitinos with different masses, and a massive vector.

  18. Targets for Combating the Evolution of Acquired Antibiotic Resistance.

    Culyba, Matthew J; Mo, Charlie Y; Kohli, Rahul M

    2015-06-16

    Bacteria possess a remarkable ability to rapidly adapt and evolve in response to antibiotics. Acquired antibiotic resistance can arise by multiple mechanisms but commonly involves altering the target site of the drug, enzymatically inactivating the drug, or preventing the drug from accessing its target. These mechanisms involve new genetic changes in the pathogen leading to heritable resistance. This recognition underscores the importance of understanding how such genetic changes can arise. Here, we review recent advances in our understanding of the processes that contribute to the evolution of antibiotic resistance, with a particular focus on hypermutation mediated by the SOS pathway and horizontal gene transfer. We explore the molecular mechanisms involved in acquired resistance and discuss their viability as potential targets. We propose that additional studies into these adaptive mechanisms not only can provide insights into evolution but also can offer a strategy for potentiating our current antibiotic arsenal.

  19. 32 year old man with "community-acquired' pneumonia

    Jill K. Gersh

    2014-04-01

    Full Text Available Background: Community-acquired pneumonia is a common reason for hospital admission; however underlying pathogens vary depending on host immunity and circulating pathogens in the community. Case Summary: A 32 year old man from Malawi presented with community-acquired pneumonia. After failing outpatient management, he was admitted and found to have underlying HIV disease. His diagnostic work up was initially inconclusive for M. tuberculosis (TB and thus his diagnostic evaluation and treatment focused on other etiologies. He was ultimately diagnosed with TB after an invasive procedure and had a rapid clinical response after initiating TB treatment. Conclusion: Both failure to recognize that TB can present with a syndrome similar to bacterial pneumonia and over-reliance on diagnostic testing delayed the diagnosis of TB. Delays in diagnosis contributed to substantial morbidity and risked nosocomial transmission. Despite declining incidence in the US, providers should remain cognizant of diagnostic limitations for TB disease and have a low threshold for empiric treatment.

    This paper presents a novel application of magnetic particles for biosensing, called label-acquired magnetorotation (LAM). This method is based on a combination of the traditional sandwich assay format with the asynchronous magnetic bead rotation (AMBR) method. In label-acquired magnetorotation, an analyte facilitates the binding of a magnetic label bead to a nonmagnetic solid phase sphere, forming a sandwich complex. The sandwich complex is then placed in a rotating magnetic field, where the rotational frequency of the sandwich complex is a function of the amount of analyte attached to the surface of the sphere. Here, we use streptavidin-coated beads and biotin-coated particles as analyte mimics, to be replaced by proteins and other biological targets in future work. We show this sensing method to have a dynamic range of two orders of magnitude.
