    Full Text Available El Síndrome de Inmunodeficiencia Adquirida (SIDA es un proceso patológico detectado por vez primera en los Estados Unidos de América en 1981 (aunque se plantea que su origen geográfico está en África. Adquiere, de inmediato, un carácter epidémico explosivo, que luego se extiende a otras partes del mundo y comienza a adoptar el carácter de un grave problema de salud mundial. Los seres humanos viven en armonía relativa con una serie de virus, bacterias, parásitos y hongos que no causan enfermedades a las personas sanas cuyas defensas inmunológicas están intactas, pero estos microorganismos pueden aprovecharse de un sistema inmunitario debilitado, como el de una persona infectada por el Virus de Inmunodeficiencia Humana (VIH. Las infecciones que ocasionan reciben el nombre de infecciones oportunistas, dentro de las cuales se encuentra la candidiasis, que es una infección fúngica causada por cualquiera de las especies del género Candida. En pacientes con VIH, la infección oportunista más frecuente es la Candida y de ésta la especie que más prevalece es la Candida albicans. La candidiasis más común es la seudomembranosa, localizada generalmente en la lengua, paladar duro y blando y la mucosa del carrillo. Las manifestaciones clínicas más frecuentes de la candidiasis son las infecciones por Candida de la cavidad bucal y el esófago. En los pacientes infectados por el VIH, asintomáticos, la presencia de candidiasis bucal suele anunciar la transición hacia el SIDA. El odontólogo puede reconocerla en sus diferentes formas de presentación y muchas veces, a través de su presencia, puede hacer diagnóstico precoz de enfermedades como el SIDA.Acquired Immunodeficiency Syndrome is a pathological process detected for the first time in 1981 in the United States (although its geographic origin is said to be in Africa.

    Diabetes mellitus (DM) has been considered to predispose to candidiasis. While poor glycemic control increases the risk of superficial candidiasis (especially oral candidiasis), invasive candidiasis is not related to DM. Invasive candidiasis is diagnosed by combination of clinical manifestation, laboratory findings and isolation of Candida spp. Strategy of treatment for invasive candidiasis is consist of prophylactic, empiric and targeted therapy. MCFG, FLCZ and AMPH-B are recommended as first line drugs for invasive candidiasis, and L-AMB, VRCZ, ITCZ are considered as alternative drugs in Japanese guideline.

    Esophageal candidiasis presents with a range of clinical findings and is rarely found among immunocompetent patient without predisposing factors. Between 20-50% of patient may be asymptomatic. One of predisposing factor of candidiasis is immunocompromised condition due to Malignancy. Dysphagia is the most frequently presented feature of esophageal carcinoma. We demonstrated a case of esophageal candidiasis as one of early clinical presentation in patient with esophageal carcinoma.

    The oropharyngeal candidiasis is a common condition in cancer patients treated by irradiation, during and after their treatment. For example, almost 70% of patients treated with chemoradiation for head and neck cancer are colonized, and 40% of symptomatic patients have an oropharyngeal candidiasis. Furthermore, we noticed an increase in non-albicans Candida strains, which are present in almost 50% of samples. Cancer treatments, especially radiation therapy, and comorbidities are risk factors of oropharyngeal candidiasis. Oropharyngeal candidiasis has substantial effects on quality of life, and may limit treatment. Epidemiologic data, physiopathology, clinical diagnosis criteria, consequences and treatment of oropharyngeal candidiasis will be discussed in this article.

    Full Text Available Introduction. Retroperitoneal sarcomas comprise a small proportion of all soft tissue sarcomas, and multiple factors influence their clinical behavior. Histopathological type and grade as well as complete surgical resection especially on the first operative attempt are well recognized as the main prognostic factors. Multifocality is another prognostic factor, which compromises therapy and finally makes prognosis worse due to multiple adverse implications. Case Presentation. A rare case of a 65-year-old male patient suffering from a multifocal retroperitoneal liposarcoma successfully treated in our hospital is presented herein. Discussion. Also, general considerations for these tumors are discussed, and especially multifocality is underlined as an ominous sign of retroperitoneal sarcomas behavior. Despite multifocality, once again complete surgical excision remains the mainstay of treatment of these patients, as long as further systemic and local therapies do not provide durable results.

    Congenital hemangiopericytoma (HPC) is a rare mesenchymal tumor with less aggressive behavior and a more favorable prognosis than similar tumors in adults. Multifocal presentation is even less common than isolated HPC and hence its clinical and histologic recognition may be challenging. A newborn infant with multifocal congenital HPC causing severe deformity but with a favorable outcome after chemotherapy and surgical removal is reported. © 2016 Wiley Periodicals, Inc.

  19. The management of superficial candidiasis.

    1999-06-01

    Superficial Candida infection includes several common conditions, most often related to some underlying local or systemic predisposition. Appropriate identification of the pathogen is important in the management of candidiasis as the result of differences in susceptibility among species and strains of Candida to different antifungal drugs. Treatment options are reviewed for oropharyngeal candidiasis, vaginal candidiasis, cutaneous candidiasis, paronychia and onychomycosis, and chronic mucocutaneous candidiasis. Because of the importance of predisposing conditions for candidiasis, adjunctive measures to abate these may be useful, although they are seldom effective in immunocompromised patients.

    An adult male mandrill (Mandrillus sphinx) suffered from chronic ulceration of the facial and gluteal skin and the oral and nasal mucosa. The ulcers were resistant to therapy and led to deterioration in the general condition of the animal. Microscopical examination revealed a severe, chronic, multifocal, granulomatous and eosinophilic dermatitis and panniculitis. There was also stomatitis and rhinitis with numerous intralesional fungal elements. These organisms were identified by immunohistochemistry, transmission electron microscopy, polymerase chain reaction and fungal culture as Candida albicans. Species identification was confirmed by MALDI-TOF mass spectrometry. A specific predisposing immunosuppressive factor for the deep chronic mucocutaneous candidiasis was not identified; however, social stress and/or a primary defect in cell-mediated immunity could not be excluded as possible causes for a predisposing immunodeficiency in the animal.

    Animal models are powerful tools to study the pathogenesis of diverse types of candidiasis. Murine models are particularly attractive because of cost, ease of handling, technical feasibility, and experience with their use. In this chapter, we describe methods for two of the most popular murine models of disease caused by Candida albicans. In an intravenously disseminated candidiasis (DC) model, immunocompetent mice are infected by lateral tail vein injections of a C. albicans suspension. Endpoints include mortality, tissue burdens of infection (most importantly in the kidneys, although spleens and livers are sometimes also assessed), and histopathology of infected organs. In a model of oral/esophageal candidiasis, mice are immunosuppressed with cortisone acetate and inoculated in the oral cavities using swabs saturated with a C. albicans suspension. Since mice do not die from oral candidiasis in this model, endpoints are tissue burden of infection and histopathology. The DC and oral/esophageal models are most commonly used for studies of C. albicans virulence, in which the disease-causing ability of a mutant strain is compared with an isogenic parent strain. Nevertheless, the basic techniques we describe are also applicable to models adapted to investigate other aspects of pathogenesis, such as spatiotemporal patterns of gene expression, specific aspects of host immune response and assessment of antifungal agents, immunomodulatory strategies, and vaccines.

    2017-05-01

    Healthy children may develop candidal infections as the result of exposure to antibiotics or corticosteroids, but chronic candidiasis in children after the newborn period is unusual. Chronic mucocutaneous candidiasis (CMC) refers to a group of conditions characterized by recurrent or persistent infections with Candida species, particularly Candida albicans. CMC is a phenotype observed in a spectrum of immunologic disorders, some with endocrinologic and autoimmune features. CMC can arise secondary to inherited or acquired T cell deficiencies, but in children is largely due to inborn errors impairing the dectin pathway and IL-17 immunity. We review the current understanding of the pathogenesis of chronic mucocutaneous candidiasis and discuss the immunologic pathways by which the immune system handles Candida. We highlight the historical and recent knowledge of CMC in children, emphasizing recent insights into basic science aspects of the dectin pathway, IL-17 signaling, consequences of AIRE gene defects, and clinical aspects of inheritance, and features that distinguish the different syndromes. The clinical phenotype of CMC has many underlying genetic causes. Genetic testing is required for definitive diagnosis.

    Multifocal humeral fractures are extremely rare. These may affect the neck and the shaft, the shaft alone, or the diaphysis and the distal humerus. There is no classification of these fractures in the literature. From 2004 to 2010, 717 patients with humeral fracture were treated surgically at our department. Thirty-five patients presented with an associated fracture of the proximal and diaphyseal humerus: synthesis was performed with plate and screws in 34 patients, and the remaining patient had an open fracture that was treated with an external fixator. Mean follow-up was 3 years and 3 months. A classification is proposed in which type A fractures are those affecting the proximal and the humeral shaft, type B the diaphysis alone, and type C the diaphysis in association with the distal humerus. Type A fractures are then divided into three subgroups: A-I, undisplaced fracture of the proximal humerus and displaced shaft fracture; A-II: displaced fracture of the proximal and humeral shaft; and A-III: multifragmentary fracture affecting the proximal humerus and extending to the diaphysis. Multifocal humeral fractures are very rare and little described in the literature, both for classification and treatment. The AO classification describes bifocal fracture of the humeral diaphysis, type B and C. The classification suggested in this article mainly concerns fractures involving the proximal and humeral shaft. A simple classification of multifocal fractures is suggested to help the surgeon choose the most suitable type of synthesis for surgical treatment. Copyright © 2013 Elsevier Ltd.

    Candida species inhabit the mucosal surfaces of healthy individuals. Major forms of oral candidiasis are pseudomembranous and atrophic form, but chronic hyperplastic candidiasis (CHC) is rarely seen. We encountered a nodule caused by candidal infection on a forearm flap in the oral cavity mimicking a recurrent tongue cancer, which revealed as CHC by histopathological examination. Like other forms of oral candidiasis, the nodule well responded to the treatment of antifungal agents and eventually disappeared. When an intraoral nodule is observed, the possibility of CHC should be taken into consideration. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

    Alio, Jorge L; Plaza-Puche, Ana B; Férnandez-Buenaga, Roberto; Pikkel, Joseph; Maldonado, Miguel

    Multifocal intraocular lenses are increasingly used in the management of pseudophakic presbyopia. After multifocal intraocular lens implantation, most patients do not need spectacles or contact lenses and are pleased with the result. Complications, however, may affect the patient's quality of life and level of satisfaction. Common problems with multifocal lenses are blurred vision and photic phenomena associated with residual ametropia, posterior capsule opacification, large pupil size, wavefront anomalies, dry eye, and lens decentration. The main reasons for these are failure to neuroadapt, lens dislocation, residual refractive error, and lens opacification. To avoid patient dissatisfaction after multifocal intraocular lens implantation, it is important to consider preoperatively the patient's lifestyle; perform an exhaustive examination including biometry, topography, and pupil reactivity; and explain the visual expectations and possible postoperative complications.

    Previous studies on soft multifocal contact lens myopia control published in the peer-reviewed literature reported findings of noncommercial contact lenses worn for 1 year or less. This study sought to determine the progression of myopia and axial elongation of children fitted with commercially available distance center soft multifocal contact lenses for 2 years. Eight- to eleven-year-old children with -1.00 D to -6.00 D spherical component and less than 1.00 D astigmatism were fitted with soft multifocal contact lenses with a +2.00 D add (Proclear Multifocal "D"; CooperVision, Fairport, NY). They were age- and gender-matched to participants from a previous study who were fitted with single-vision contact lenses (1 Day Acuvue; Vistakon, Jacksonville, FL). A-scan ultrasound and cycloplegic autorefraction were performed at baseline, after 1 year, and after 2 years. Multilevel modeling was used to compare the rate of change of myopia and axial length between single-vision and soft multifocal contact lens wearers. Forty participants were fitted with soft multifocal contact lenses, and 13 did not contribute complete data (5 contributed 1 year of data). The adjusted mean ± standard error spherical equivalent progression of myopia at 2 years was -1.03 ± 0.06 D for the single-vision contact lens wearers and -0.51 ± 0.06 for the soft multifocal contact lens wearers (p < 0.0001). The adjusted mean axial elongation was 0.41 ± 0.03 and 0.29 ± 0.03 for the single-vision and soft multifocal contact lens wearers, respectively (p < 0.0016). Soft multifocal contact lens wear resulted in a 50% reduction in the progression of myopia and a 29% reduction in axial elongation during the 2-year treatment period compared to a historical control group. Results from this and other investigations indicate a need for a long-term randomized clinical trial to investigate the potential for soft multifocal contact lens myopia control.

    Full Text Available La aparición precoz de enfermedades bucales infecciosas y transmisibles en niños, como caries dentales y enfermedad periodontal, resulta de un desequilibrio entre los mecanismos defensivos del huésped y la virulencia de microorganismos presentes en el medio bucal, a favor de estos últimos. La erupción dentaria que comienza desde el primer año de vida brinda nuevos hábitat a las bacterias en el medio bucal como la superficie del esmalte dental y el surco gingival en el paradencio de inserción dentaria, propicios para el desarrollo de especies bacterianas cariogénicas y/o paradenciopáticas. Este desarrollo es favorecido por condiciones adversas como dieta rica en azúcares fermentables, higiene bucal deficitaria, malposiciones dentarias, escasa secreción salival, hábitos prolongados nocivos como succión no nutritiva, respiración bucal, masticación mínima por ingesta de alimentos que casi no requieren procesamiento para ser deglutidos. Es prioritario controlar los circuitos de infectividad bucal, especialmente durante la primera infancia, cuando el sistema inmune del niño aún está inmaduro y comienza a tomar contacto con antígenos. La madre por el estrecho vínculo físico con su hijo resulta el principal transmisor de gérmenes, sumado a la fase de reconocimiento oral del niño de su propio cuerpo y el entorno. Pese a ello el niño cuenta desde el nacimiento con mecanismos de defensa innatos y otros adquiridos pasivamente en la gestación y a través de la lactancia materna, que dificultan el desarrollo de enfermedades infecciosas bucales y sistémicas

El tratamiento medicamentoso de esas afecciones puede tener un impacto negativo en la salud bucal. El objetivo del presente estudio fue profundizar en los conocimientos sobre el asma en niños y adolescentes, de los fámacos y dispositivos terapéuticos utilizados y relacionarlos con los eventos adversos observados a nivel bucal. La revisión bibliográfica realizada demuestra que el uso de medicació por vía inhalatoria para las afecciones respiratorias no infecciosas se relaciona con reacciones adversas como la erosión, caries dental, gingivitis, halitosis, candidiasis y xerostomía. El relevamiento realizado en pacientes del Centro Hospitalario Pereira Rossell (2009-2010 mostró una correlación positiva entre los datos de la bibliografía revisada y lo observado en la clínica. Teniendo en cuenta estos antecedentes, es de importancia que el equipo de salud reconozca a la población que utiliza inhaladores como de alto riesgo potencial para el desarrollo de patologías bucales, enfatizando la necesidad de contar con programas educativo-preventivos específicos. La atención para la salud de los pacientes portadores de afecciones respiratorias requiere de un abordaje multidisciplinario

    The role of gastric acid inhibitors as predisposing factors for Candida esophagitis is unknown. A retrospective case-control study of esophageal candidiasis was conducted in human immunodeficiency virus (HIV)-negative patients diagnosed from January 1991 to December 1997. The diagnosis of esophageal candidiasis was always made on the basis of endoscopic and histological criteria. Fifty-one patients were diagnosed with esophageal candidiasis, 15 of whom had esophageal complaints and 48 of whom suffered from another previous chronic disease (17 had cancer). In addition, 20 patients had previously been treated with antibiotics, 13 with steroids and 14 with omeprazole. In the multivariate analysis, neoplasm (odds ratio, 5.50; 95% confidence interval, 1.94-15.56) and therapy with antibiotics (odds ratio, 11.97; 95% confidence interval, 3.82-37.45), steroids (odds ratio, 35.52; 95% confidence interval, 3.90-324.01) or omeprazole (odds ratio, 18.23; 95% confidence interval, 4.67-71.03) were all associated with esophageal candidiasis. These data suggest that Candida esophagitis tends to occur in patients with chronic diseases, most of whom have been previously treated with antibiotics, steroids or omeprazole. The findings support the hypothesis that treatment with omeprazole favors the development of esophageal candidiasis.

  18. Immunologic aspects of oral candidiasis.

    Immunity to Candida infections in human beings is complex because of the different types of candidiasis, the different forms of Candida itself, and the interrelationships between the mucosal and systemic immune systems. Mucosal infection is by far the most common type of candidiasis, but systemic infection can also occur and the mechanisms for each may be quite different. In the oral cavity there are four main types of candidiasis, and hyphal and yeast forms of Candida may be present with both common and unique antigens. Humoral immunity is represented by salivary antibodies of the mucosal immune system and serum antibodies in the mucosa. Cell-mediated immunity may play a role particularly in chronic hyperplastic candidiasis. Salivary antibodies have been shown to inhibit adherence of Candida to buccal epithelial cells and to be protective in animal models. Serum antibodies against a 47kD antigen have been shown to correlate with protection and recovery from systemic candidiasis, but there is little evidence for a role of serum antibody in protection against infection of the oral cavity. In in vitro studies, both macrophages and polymorphonuclear leukocytes can kill yeast forms and inhibit hyphal forms of Candida and because chronic hyperplastic candidiasis is associated with intraepithelial polymorphonuclear leukocytes, these cells could be operative in vivo. Saliva contains a number of antifungal proteins including histatins and calprotectin that could act synergistically with specific factors. It is possible that cellular factors provide the main form of defense against mucocutaneous infection, whereas humoral factors play a larger role in the prevention of dissemination of Candida infections.(ABSTRACT TRUNCATED AT 250 WORDS)

    Multifocal tuberculosis is defined as the presence of lesions affecting at least two extrapulmonary sites, with or without pulmonary involvement. This retrospective study of 10 cases aims to investigate the clinical and evolutionary characteristics of multifocal tuberculosis. It included 41 cases with tuberculosis collected between 1999 and 2013. Ten patients had multifocal tuberculosis (24%): 9 women and 1 man, the average age was 50 years (30-68 years). Our patients were correctly BCG vaccinated. The evaluation of immunodepression was negative in all patients. 7 cases had lymph node tuberculosis, 3 cases digestive tuberculosis, 2 cases pericardial tuberculosis, 2 cases osteoarticular tuberculosis, 1 case brain tuberculosis, 2 cases urinary tuberculosis, 4 cases urogenital tuberculosis, 1 case adrenal tuberculosis, 1 case cutaneous and 1 case muscle tuberculosis. All patients received anti-tuberculosis treatment for a mean duration of 10 months, with good evolution. Multifocal tuberculosis is difficult to diagnose. It can affect immunocompetent patients but often has good prognosis. Anti-tuberculosis therapy must be initiated as soon as possible to avoid sequelae.

    The calcifying epithelial odontogenic tumor (CEOT), or Pindborg tumor, is a rare and benign odontogenic neoplasm that affects the jaw. The most common manifestation of CEOT is a unifocal or localized lesion of the involved jaw, which may appear clinically as a hard tissue swelling and radiographically as a mixed radiolucent-radiopaque mass. In this article, we present a unique case of CEOT affecting multiple sites in the maxilla and mandible of a 51-year-old white man. Though biopsy samples from all involved sites revealed similar histopathologic features consistent with CEOT, the fact that there was a multifocal presentation is an unusual phenomenon for CEOT and has never been reported. Multifocal odontogenic lesions are not typical but have been observed in conditions associated with known genetic mutations. For example, multiple odontogenic keratocysts are the most common feature of the inherited condition known as nevoid basal cell carcinoma syndrome. This case, however, is the first one to demonstrate that there may be a multifocal variant of CEOT that has not been previously recognized.

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

    The incidence of oral candidiasis has increased in the elderly in recent years. Although the increase of the elderly population plays a big role in this rise of oral candidiasis, the broader recognition that elderly people have higher infection rates for oral candidiasis is considered to be also an important factor. Oral candidiasis can be categorized into three types. Pseudomembranous oral candidiasis is characterized by the appearance of white moss, erythematous oral candidiasis by the eruption of erythema, and hyperplastic oral candidiasis by mucosal hyperplasia. Miconazole has been commonly used when treating oral candidiasis. Elderly patients, however, have a tendency to develop oral candidiasis repeatedly. It is therefore critical to take measures to prevent recurrence. We recommend the use an oral moisturizer containing hinokitiol, an antifungal substance, on a regular basis, to help prevent recurrence of oral candidiasis.

    Full Text Available La enfermedad injerto contra huésped es la principal complicación que sufren los pacientes que han recibido trasplante alogénico. Se produce como consecuencia de una reacción inflamatoria exagerada mediada por los linfocitos del donante y estimulada por aquellos tejidos que han sido lesionados por la enfermedad de base, por las infecciones previas o por el tratamiento de acondicionamiento. El diagnóstico es clínico e histopatológico. Los pacientes presentan rash maculopapular pruriginoso y doloroso que puede extenderse por toda la superficie corporal, fiebre, vómito, náuseas, diarrea y anorexia. En la mucosa bucal se observan erosiones ulceradas, extremamente dolorosas y pueden ser la primera o la única manifestación detectable clínicamente de esta enfermedad. El objetivo es presentar un caso de enfermedad de injerto contra huésped. Se trata de una mujer de 54 años de edad con linfoma no-Hodgking, que recibió tratamiento con quimioterapia, radioterapia y trasplante de células madre hematopoyéticas en el 2009. Tres meses después, presentó lesiones en la piel diagnosticadas como enfermedad injerto contra huésped y tratadas con corticoesteroides, a los seis meses fue remitida al odontólogo porque se quejaba de ardor en la boca, xerostomía y dificultad para masticar, tenía úlceras en la mucosa bucal y en la lengua. En la ocasión recibió tratamiento con corticoesteroides, clorhexidina, orientaciones de higiene bucal y controles clínicos permanentes.

    Candidiasis or oral candidiasis is the most frequent mucocutaneous mycosis of the oral cavity. It is produced by the genus Candida, which is found in the oral cavity of 53% of the general population as a common commensal organism. One hundred and fifty species have been isolated in the oral cavity, and 80% of the isolates correspond to Candida albicans, which can colonize the oral cavity alone or in combination with other species. Transformation from commensal organism to pathogen depends on the intervention of different predisposing factors that modify the microenvironment of the oral cavity and favor the appearance of opportunistic infection. The present study offers a literature review on the diagnosis of oral candidiasis, with the purpose of establishing when complementary microbiological techniques for the diagnosis of oral candidiasis should be used, and which techniques are most commonly employed in routine clinical practice in order to establish a definitive diagnosis. A Medline-PubMed, Scopus and Cochrane search was made covering the last 10 years. The diagnosis of oral candidiasis is fundamentally clinical. Microbiological techniques are used when the clinical diagnosis needs to be confirmed, for establishing a differential diagnosis with other diseases, and in cases characterized by resistance to antifungal drugs. Biopsies in turn are indicated in patients with hyperplastic candidiasis. Staining (10% KOH) and culture (Sabouraud dextrose agar) are the methods most commonly used for diagnosing primary candidiasis. Identification of the individual species of Candida is usually carried out with CHROMagar Candida®. For the diagnosis of invasive candidiasis, and in cases requiring differentiation between C. albicans and C. dubliniensis, use is made of immunological and genetic techniques such as ELISA and PCR. Key words:Clinical, oral candidiasis, microbiology.

    In patients with glioblastoma, antiangiogenic therapy with bevacizumab (BEV) has been shown to improve progression-free survival (PFS), but not overall survival (OS). Especially in patients with an unusual infiltrative phenotype as seen in multifocal glioblastoma, the use of BEV therapy is still more controversial. Therefore, we prepared a retrospective case series with 16 patients suffering from a multifocal glioblastoma treated with BEV. We compared these patients to a matched control cohort of 16 patients suffering from glioblastoma with a single lesion treated with BEV. The objective of this study was to evaluate whether the course of disease differs in glioblastoma patients with a multifocal disease pattern compared to those with a single lesion only. Patients were treated with BEV monotherapy or BEV in combination with irinotecan or lomustine (CCNU). Response rates and PFS were similar in both groups. There was a trend for an unfavorable OS in the patient group with multifocal glioblastoma, which was expected due to the generally worse prognosis of multifocal glioblastoma. We investigated whether BEV therapy affects the invasive growth pattern as measured by the appearance of new lesions on magnetic resonance imaging (MRI). Under BEV therapy, there was a trend for a lower frequency of new lesions both in multifocal and solitary glioblastoma. Based on these results, BEV therapy at relapse appears to be justified to no lesser extent in multifocal glioblastoma than in solitary glioblastoma. PMID:29156610

    Invasive candidiasis is a severe infection among onco-hematological patients, with an attributable mortality around 40%. Micafungin has shown efficacy in antifungal prophylaxis among hematopoietic stem cell transplant recipients and in the treatment of esophageal candidiasis. To assess the role of micafungin in the treatment of invasive candidiasis among onco-hematological patients. Literature review. In a study on 126 patients with candidemia treated with micafungin, an overall response rate of 83% was reported. A double-blind study of 531 patients with invasive candidiasis comparing micafungin (100mg/day) versus liposomal amphotericin B (3mg/kg/day) reported success in 90% of patients in both arms, with a more favorable safety profile with micafungin. Other double blind randomized, phase III study compared two doses of micafungin (100mg/day and 150mg/day) with standard doses of caspofungin (70mg loading dose, then 50mg/day) in adults with invasive candidiasis. Overall success rate was 74% for micafungin 100mg/day, 70% for micafungin 150mg/day, and 71% for caspofungin. A double blind randomized study compared micafungin (2mg/kg/day) to liposomal amphotericin B (3mg/kg/day) in the treatment of invasive candidiasis in children with a predominance of infections with non-albicans Candida spp. Overall success rate was similar (73% for micafungin and 76% for liposomal amphotericin B). Comparative phase III studies have demonstrated non-inferiority of micafungin compared to standard antifungal agents for invasive candidiasis. Micafungin is safe and effective in the treatment of children and adults with invasive candidiasis. Effectivity in invasive infections caused by non-albicans Candida spp is especially relevant in onco-hematological patients receiving fluconazole prophylaxis.

    Introduction: Candidiasis or oral candidiasis is the most frequent mucocutaneous mycosis of the oral cavity. It is produced by the genus Candida, which is found in the oral cavity of 53% of the general population as a common commensal organism. One hundred and fifty species have been isolated in the oral cavity, and 80% of the isolates correspond to Candida albicans, which can colonize the oral cavity alone or in combination with other species. Transformation from commensal organism to pathog...

    A novel liquid crystal microlens array with tunable multifocal capability, high optical power and fill-factor is proposed and experimentally demonstrated. A specific hole pattern design produces a multifocal array with only one voltage control. Three operations modes are possible, "Off", "Tunable Multifocal" and "Unifocal". The design is patterned in both substrates. Then, the substrates are arranged in symmetrical configuration. The result is a high optical power in comparison with typical hole patterned structures. Besides, it is proposed a hexagonal pattern that produces a high fill factor, specially indicated for some applications as Integral Imaging. The array has several useful characteristics for this type of application: tunability for the loss of resolution; multifocal for extended DOF; high fill factor for increase the number of views; and low power consumption for integration in portable devices. Moreover, the optical characteristics of the proposed device could bring new applications in other fields.

    Full Text Available Renal oncocytomas are the most common benign solid renal tumor, accounting for 3-7% of renal neoplasms. Oncocytomas are multifocal in 2-12% and bilateral in 4-14% of cases. Multifocal bilateral oncocytomas represent only 1.4% of renal cases. We present an extraordinary case of a patient with multifocal bilateral renal oncocytomas during pregnancy. An electronic literature search revealed fewer than 30 reports of on cases of bilateral multifocal renal oncocytomas, none of them occurring in pregnancy. The management of this patient differed from the recommended guidelines for renal masses suspected to be malignant because elective caesarean section and nephrectomy in the second trimester was refused.

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

    Multifocal contact lenses have been growing in popularity as a modality to correct presbyopic eyes, although visual side effects such as disability glare have been reported. The objective of this study was to investigate the effect of multifocal contact lenses on disability glare by means of ocular straylight. A prospective randomized, comparative study was performed that included 16 subjects free of ocular pathology. Straylight was measured using a commercial straylight meter with the natural and dilated pupil. Participants were fitted with Proclear Multifocal (Distance/Near), ACUVUE Oasys for Presbyopia, and Air Optix Aqua Multifocal randomized to the left or right eye. Straylight measurements were repeated with the contact lens in situ after the pupil dilation. Results obtained with the dilated pupil without contact lens acted as a control. Diameter of the natural and dilated pupil was 2.87 ± 0.40 mm and 7.45 ± 0.86 mm, respectively (P lenses, a significant difference was only found between Air Optix and the control group (P = .006). The latter showed also slightly increased light scatter. A difference in measured straylight was found between the studied multifocal lenses. The observed variability and the straylight-pupil size dependency should be taken into account to avoid elevated straylight in multifocal contact lens wearers. The reason for the observed differences in straylight must be the subject of future studies.

    Our objective was to study the incidence, etiology, and diagnosis of multifocal osteonecrosis (MFON) and its treatment options to facilitate an earlier diagnosis and to optimize treatment. A radiological investigation was performed in osteonecrosis patients with a high risk of MFON for a more accurate diagnosis between January 2010 and June 2015. For patients with osteonecrosis of both the hip and knee joints or for patients with a history of corticosteroid use or alcohol abuse who had osteonecrosis of one or more joints in the shoulder, ankle, wrist or elbow, magnetic resonance imaging (MRI) was also performed on other joints, regardless of whether these joints were symptomatic. Furthermore, we performed a radiological screening of 102 patients who had a negative diagnosis of MFON but were at a high risk; among them, another 31 MFON cases were successfully identified (30.4%). Thus, the incidence of MFON during the study period increased from 3.1% to 5.2%. Patients diagnosed with osteonecrosis and who are at a high risk of MFON should have their other joints radiologically examined when necessary. This will reduce missed diagnosis of MFON and facilitate an earlier diagnosis and treatment to achieve an optimal outcome. PMID:27404962

  11. Experimental superficial candidiasis on tissue models.

    Jayatilake, J A M S; Samaranayake, L P

    2010-07-01

    Candida species are common pathogens causing superficial mycoses primarily affecting the mucosa and the skin in humans. Crucial steps during pathogenesis of superficial candidiasis comprise fungal adhesion, colonisation and subsequent penetration of the respective tissues. Exploring these pathological events and perhaps fungal and tissue responses towards drug treatment is imperative in the management of this infection. Unfortunately, pathological biopsies of superficial candidiasis do not exhibit the early changes in the host-pathogen interaction as the tissues are already invaded by the fungi. In vivo experimental assessments of pathological processes of superficial candidiasis are also limited because of the difficulties in providing reproducible and comparable conditions in the host environment. Conversely, in vitro models have helped studying fungal-host interactions under more defined and controlled conditions. Some common in vitro models used to simulate superficial candidiasis are chick chorioallantoic membrane, mucosal explants and single layer or multiple layer cell cultures. Interestingly, these experimental approaches share advantages as well as disadvantages when compared with in vivo conditions. Hence, this review intends to discuss about the experimental superficial candidiasis produced in various tissue models and their advantages as well as disadvantages with a particular reference to further improvement of validity and reliability of such experiments.

    A 47-year-old woman presented with persistent dysphagia. A gastroendoscopy revealed massive esophageal candidiasis, and oral miconazole was prescribed. Three weeks later, she returned to our hospital without symptomatic improvement. She was febrile, and blood tests showed leukocytosis (137,150 /μL, blast 85%), anemia and thrombocytopenia. She was diagnosed with acute myeloid leukemia (AML). She received chemotherapy and antimicrobial agents. During the recovery from the nadir, bilateral ocular candidiasis was detected, suggesting the presence of preceding candidemia. Thus, esophageal candidiasis can be an initial manifestation of AML. Thorough examination to detect systemic candidiasis is strongly recommended when neutropenic patients exhibit local candidiasis prior to chemotherapy.

    Candidiasis is defined as an infection or disease caused by a fungus of the genus Candida. Rate of disseminated candidiasis increases with the growth of the number of immunocompromised patients. In the the last few decades the incidence of disseminated candidiasis is in growth as well as the mortality rate. The aim of this survey is to show the importance of serological tests implementation in disseminated candidiasis diagnose. This is a prospective study involving 60 patients with malign diseases with and without clinical signs of disseminated candidiasis and 30 healthy people who represent the control group. Apart from hemoculture, detection of circulating mannan antigen and adequate antibodies of Candida species applying comercial ELISA test was determined in each patient. This survey deals with relevant factors causing disseminated candidiasis. This survey showed that the group of patients with clinical signs of disseminated candidiasis had more patients with positive hemoculture to Candida species, then the group of patients without clinical signs of disseminated candidiasis. The number of patients being examined and positive to antigens and antibodies was higher (p candidiasis (7/30; 23.3%), then in the group of patients without clinical signs of disseminated candidiasis (0/30; 0%): Average value of titra antigen was statistically higher (p candidiasis 6/30 (20%) of patients had Candida spp.positive hemocultures while in the group of patients without clinical signs of disseminated candidiasis 1/30 (3.3%) of patients had Candida spp. positive hemocultures, which was considerably higher (p candidiasis were statistically significant, while correlation of results of hemoculture and antibodies was insignificant. Because of low sensitivity of hemoculture and time needed for isolation of Candida spp., introducing serological tests in regular procedures would speed disseminated candidiasis diagnose.

    Full Text Available Candidiasis is a multifaceted fungal disease including mucosal-cutaneous, visceral, and disseminated infections caused by yeast species of the genus Candida. Candida infections are among the most common human mycoses. Candida species are the third to fourth most common isolates from bloodstream infections in neutropenic or immunocompromised hospitalized patients. The mucosal-cutaneous forms—particularly vaginal infections—have a high prevalence. Vaginitis caused by Candida species is the second most common vaginal infection. Hence, candidiasis is a major subject for research, including experimental in vivo models to study pathogenesis, prevention, or therapy of the disease. The following review article will focus on various experimental in vivo models in different laboratory animals, such as mammals (mice, rats, rabbits, the fruit fly–Drosophila melanogaster, the larvae of the moth Galleria mellonella, or the free-living nematode Caenorhabditis elegans. The review will describe the induction of the different clinical forms of candidiasis in the various models and the validity of such models in mimicking the human clinical situations. The use of such models for the assessment of antifungal drugs, evaluation of potential vaccines to protect before candidiasis, exploration of Candida virulence factors, and comparison of pathogenicity of different Candida species will be included in the review. All of the above will be reported as based on published studies of numerous investigators as well as on the research of the author and his group.

    To evaluate the refractive outcomes after multifocal intraocular lens (IOL) exchange. Cullen Eye Institute, Baylor College of Medicine, Houston, Texas, USA. Retrospective case series. Patients had multifocal IOL explantation followed by IOL implantation. Outcome measures included type of IOL, surgical indication, corrected distance visual acuity (CDVA), and refractive prediction error. The study comprised 29 patients (35 eyes). The types of IOLs implanted after multifocal IOL explantation included in-the-bag IOLs (74%), iris-sutured IOLs (6%), sulcus-fixated IOLs with optic capture (9%), sulcus-fixated IOLs without optic capture (9%), and anterior chamber IOLs (3%). The surgical indication for exchange included blurred vision (60%), photic phenomena (57%), photophobia (9%), loss of contrast sensitivity (3%), and multiple complaints (29%). The CDVA was 20/40 or better in 94% of eyes before the exchange and 100% of eyes after the exchange (P = .12). The mean refractive prediction error significantly decreased from 0.22 ± 0.81 diopter (D) before the exchange to -0.09 ± 0.53 D after the exchange (P < .05). The median absolute refractive prediction error significantly decreased from 0.43 D before the exchange to 0.23 D after the exchange (P < .05). Multifocal IOL exchange can be performed safely with good visual outcomes using different types of IOLs. A lower refractive prediction error and a higher likelihood of 20/40 or better vision can be achieved with the implantation of the second IOL compared with the original multifocal IOL, regardless of the final IOL position.

    This study aimed to examine the incidence, epidemiology, and clinical characteristics of symptomatic and asymptomatic candidiasis in a pediatric intensive care unit (PICU), and to determine the risk factors associated with symptomatic candidiasis. This retrospective study included 67 patients from a 7-bed PICU in a tertiary care hospital that had Candida-positive cultures between April 2007 and July 2009. Demographic and clinical characteristics of the patients, Candida isolates, antimicrobial and antifungal treatments, and previously identified risk factors for symptomatic candidiasis were recorded, and symptomatic and asymptomatic patients were compared. In all, 36 (53.7%) of the patients with Candida-positive cultures had asymptomatic candidiasis and 31 (46.3%) had symptomatic candidiasis. Candida albicans was the most common Candida sp. in the asymptomatic patients (n = 20, 55.6%), versus Candida parapsilosis in the symptomatic patients (n = 15, 48.4%). The incidence of central venous catheter indwelling, blood transfusion, parenteral nutrition, and surgery was higher in the symptomatic patient group than in the asymptomatic patient group (P candidiasis according to forward stepwise multivariate logistic regression analysis (OR: 6.1; 95% CI: 1.798-20.692). Surgery was the only risk factor significantly associated with symptomatic candidiasis and non-albicans Candida species were more common among the patients with symptomatic candidiasis. While treating symptomatic candidiasis in any PICU an increase in the incidence of non-albicans candidiasis should be considered.

    Increased weakness during cold (cold paresis) was reported in single cases of multifocal motor neuropathy (MMN). This was unexpected because demyelination is a feature of MMN and symptoms of demyelination improve, rather than worsen, in cold. It was hypothesized that cold paresis in MMN does not reflect demyelination only, but may indicate the existence of inflammatory nerve lesions with permanently depolarized axons that only just conduct at normal temperature, but fail at lower temperatures...

    OBJECTIVE Invasive candidiasis is a leading cause of infection-related morbidity and mortality in extremely low-birth-weight (candidiasis. METHODS The study involved a prospective observational cohort of infants candidiasis. Two models were generated with invasive candidiasis as their outcome: 1) potentially modifiable risk factors and 2) a clinical model at time of blood culture to predict candidiasis. RESULTS Invasive candidiasis occurred in 137/1515 (9.0%) infants and was documented by positive culture from ≥ 1 of these sources: blood (n=96), cerebrospinal fluid (n=9), urine obtained by catheterization (n=52), or other sterile body fluid (n=10). Mortality was not different from infants who had positive blood culture compared to those with isolated positive urine culture. Incidence varied from 2–28% at the 13 centers enrolling ≥ 50 infants. Potentially modifiable risk factors (model 1) included central catheter, broad-spectrum antibiotics (e.g., third-generation cephalosporins), intravenous lipid emulsion, endotracheal tube, and antenatal antibiotics. The clinical prediction model (model 2) had an area under the receiver operating characteristic curve of 0.79, and was superior to clinician judgment (0.70) in predicting subsequent invasive candidiasis. Performance of clinical judgment did not vary significantly with level of training. CONCLUSION Prior antibiotics, presence of a central catheter, endotracheal tube, and center were strongly associated with invasive candidiasis. Modeling was more accurate in predicting invasive candidiasis than clinical judgment. PMID:20876174

    44 cases of oral candidiasis were studied histopathologically. We have found out that the microabscess in superficial epithelium is the histologic symbol of oral candidiasis. So, for those cases with microabscess, PAS stain should be done in order to make definite diagnosis. Epithelial dysplasia was observed in 8 cases (18.2%). Clinically these 8 cases were chronic hyperplastic oral candidiasis, this means that the long term follow-up study should be done for those with chronic hyperplastic oral candidiasis. Inflammatory infiltration was related to the amount of candida. The more candida get into the epithelium, the heavier inflammation is.

    The study investigated the effect of the design of multifocal contact lenses on the sensitivity to contrast and disability glare. Contrast sensitivity was measured in 16 young adults (mean age: 25.5±2.5years) at a distance of 2m under two conditions: no-glare and glare. Two designs (Center Near and Center Distance) of the Biofinity soft contact lens were used to simulate correction for presbyopes, while a correction with single vision trial lenses and contact lenses acted as controls. The design of the used multifocal contact lenses had a significant influence on the log area under the curve of the contrast sensitivity function (AUC-CSF). Compared to the spectacle lens correction, the AUC-CSF was significantly reduced, in case CS was measured with the Center Near design lens, under the no-glare (pCenter Distance design contact lens, the AUC-CSF was significantly smaller in case CS was tested under glare (p=0.001). Disability glare (DG) was depending on the spatial frequency and the design of the multifocal lens, while the Center Distance design produced higher amounts of DG (pcontact lenses has a significant impact on the contrast sensitivity as well as the disability glare. In order to dispense the best correction in terms of contact lenses, the sensitivity to contrast under no-glare and glare conditions should be tested a medium spatial frequencies. Copyright © 2017.

    Background Maculopathy is a potential side effect of amyl nitrite or "poppers" abuse. It is characterized by a sudden, painless decrease in visual acuity. While the funduscopic changes are subtle, optical coherence tomography shows alterations of the outer retinal layers in the fovea. However, the extent of retinal dysfunction remains poorly understood. Materials/Methods We compared the multifocal electroretinogram of 6 patients with poppers maculopathy to that of a control group consisting of 6 healthy subjects. Response densities and implicit times of N1 and P1 were analyzed. Results Response densities and implicit times of both N1 and P1 were lower in the patients with poppers maculopathy than in the control group, particularly in ring 1 and rings 4 and 5. The only statistically significant finding, however, was a reduced N1 response density of one hexagon in the patient group. No significant differences were found considering the sum response or the averaged rings 1 to 5. Conclusion Compared to a healthy control group, the multifocal electroretinogram of patients with poppers maculopathy shows no relevant impairment. This contrasts the marked effect of the disease on visual acuity. In clinical practice, poppers maculopathy cannot be diagnosed by multifocal electroretinography.

    Chronic mucocutaneous candidiasis (CMC) is a rare disease associated with immunodeficiency and characterized by persistent and refractory infections of the skin, appendages and mucous membranes caused by members of the genus Candida. Several different disorders are classified under this common denominator, including chronic and recurrent mucocutaneous infections due to Candida spp., which are sometimes linked to autoimmune endocrinopathies. These fungal infections are usually confined to the mucocutaneous surface, with little propensity for systemic disease or septicemia. We describe a patient with CMC who had an esophageal candidiasis refractory to treatment for decades and who developed an epidermoid esophageal cancer. No risk factors such as familiar susceptibility, smoking, alcohol drinking, or living in an endemic area were verified. This case report suggests the participation of nitrosamine compounds produced by chronic Candida infections as a risk factor for esophageal cancer in a patient with autosomal-dominant chronic mucocutaneous candidiasis.

    Full Text Available INTRODUCTION Hepatosplenic candidiasis is a disseminated invasive fungal infection that may affects patients with acute leukemia. The main clinical manifestation is a persistent fever in patients recovered from prolonged neutropenia after recent chemotherapy. CASE OUTLINE The authors present three patients, two women and one men, aged 23, 26 and 33 years, with acute leukemia; one with acute myeloblastic and two with acute lymphoblastic leukemia who developed hepatosplenic candidiasis. The diagnosis was based on prolonged fever, elevated serum bilirubin and alkaline phosphatase, as well as characteristic lesions on computed tomography, nuclear magnetic resonance and ultrasonographic findings and positive blood culture in one patient. The antifungal treatment was successful in one patient only. Two patients died due to progression of leukemia. CONCLUSION If leukemia patient in remission after chemotherapy develops a prolonged fever of unknown origin, hepatosplenic candidiasis has to be considered and all efforts should be done to diagnose it. The diagnosis is based on clinical presentation and imaging techniques. The positive cultures of fungi are not usually possible and are not mandatory. The antifungal treatment may be prolonged, sometimes 2 to 3 months or even more.

    Candidemia and disseminated candidiasis are major causes of morbidity and mortality in hospitalized patients especially in the intensive care units (ICU). The incidence of invasive candidasis is on a steady rise because of increasing use of multiple antibiotics and invasive procedures carried out in the ICUs. Worldwide there is a shifting trend from C. albicans towards non albicans species, with an associated increase in mortality and antifungal resistance. In the ICU a predisposed host in one who is on broad spectrum antibiotics, parenteral nutrition, and central venous catheters. There are no pathognomonic signs or symptoms. The clinical clues are: unexplained fever or signs of severe sepsis or septic shock while on antibiotics, multiple, non-tender, nodular erythematous cutaneous lesions. The spectrum of infection with candida species range from superficial candidiasis of the skin and mucosa to more serious life threatening infections. Treatment of candidiasis involves removal of the most likely source of infection and drug therapy to speed up the clearance of infection. Amphotericin B remains the initial drug of first choice in hemodynamically unstable critically ill children in the wake of increasing resistance to azoles. Evaluation of newer antifungal agents and precise role of prophylactic therapy in ICU patients is needed.

    Science.gov (United States)

    2009-01-01

    This document summarizes current knowledge about diagnosis and treatment of candidiasis affecting the skin and oral mucosa. Several clinical forms of mucocutaneous candidiasis are distinguished depending on a patient's age and infected site, e.g. Candida intertrigo, erythema mycoticum infantile, erosio interdigitalis blastomycetica, candidal paronychia and onychia, Candida onychomycosis, and oral candidiasis. The diagnosis of candidiasis is confirmed by observation of mycelial forms on microscopic examination. Since Candida yeasts (especially C. albicans) are normal inhabitants of the skin and oral mucosa, it must always be noted that positive culture does not always indicate the presence of candidal infection. The pathogenicity of Candida species is relatively low, and some special conditions are required for tissue invasion by the fungus. Predisposing factors, such as disturbances of the cutaneous and mucosal microenvironment and systemic or local immunosuppression, should be checked in patients with recurrent infection. Therapy for cutaneous candidiasis is dominated by topical antifungal agents. Azole antifungal cream (e.g., bifonazole, ketoconazole, neticonazole hydrochloride, lanoconazole and luliconazole) is most effective. Terbinafine hydrochloride and amorolfine hydrochloride are also useful. Cutaneous candidiasis usually requires a shorter duration of topical treatment (1-2 weeks) than superficial dermatophyte infections. For candidal paronychia and onychomycosis, oral therapy with itraconazole is recommended. The daily dose of itraconazole should be taken for several months, while its pulse therapy for candidiasis is not approved in Japan. Itraconazole oral solution is commonly used for oral candidiasis, and miconazole gel is also effective.

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

    Full Text Available Modern day cataract surgery is evolving from a visual restorative to a refractive procedure. The advent of multifocal intraocular lenses (MFIOLs allows greater spectacle independence and increased quality of life postoperatively. Since the inception in 1980s, MFIOLs have undergone various technical advancements including trifocal and extended depth of vision implants more recently. A thorough preoperative workup including the patients' visual needs and inherent ocular anatomy allows us to achieve superior outcomes. This review offers a comprehensive overview of the various types of MFIOLs and principles of optimizing outcomes through a comprehensive preoperative screening and management of postoperative complications.

    Objectives: Oral candidiasis (OC) is a frequent oral lesion in renal transplant patients (RTPs). Despite the increased prevalence of OC in RTPs, no study has examined related risk factors. The aims of this study were to analyze the prevalence of and risk factors for OC in RTPs compared with age- and gender-matched healthy control group (HC) as well as determine the incidence of OC after transplantation. Study Design: We analyzed the prevalence and risk factors of OC in a group of 500 RTPs (307 men, 193 women, mean age 53.63 years) and 501 HC subjects (314 men, 187 women, mean age 52.25 years). Demographic and pharmacological data were recorded for all subjects. Incident cases of OC were ascertained retrospectively from outpatient clinical records only in the RTP group. Results: The prevalence of OC was 7.4% in RTPs compared with 4.19% in HC (P<0.03). The most frequent type of OC in the two groups was denture stomatitis. Statistical association was found between OC and age, mycophenolate mofetil dose and blood levels, dentures and tobacco. The multiple logistic regression model only chose for denture variable. According to the outpatient clinical records, 24 RTPs suffered OC during the first moth post-transplant. Severe lesions affecting the oral cavity and pharynx appeared in 79% of the OC cases. Conclusions: This study shows a lower prevalence of OC in RTPs than previous reports. Denture stomatitis was the most frequent OC prevalence form described in RTPs. Severe candidiasis is more frequent in the immediate posttransplant period. The presence of denture is an important risk factor of OC. These results emphasise the importance of adequate pre- and post-transplant oral health and denture cleaning and adjustment is recommended for these subjects to prevent this infection.

    Candida organisms live on the skin and mucous membranes of up to 75 percent of the population. They can live commensally without causing harm or can change to an aggressive form and invade tissue, causing both acute and chronic disease in the host. Oropharyngeal candidiasis manifests clinically as acute pseudomembranous, acute atrophic, chronic atrophic, chronic hypertrophic/hyperplastic, and angular cheilitis. Systemic infection leading to candidemia can be devastating and cause up to a 60 percent mortality rate in medical or post-surgical intensive care wards. Oral nystatin, clotrimazole, and fluconazole usually provide appropriate therapy; although resistance to medications is increasing, particularly in immunocompromised hosts.

    Age alone is not usually sufficient for the development of disease due to Candida, but it appears to be associated with increased morbidity and mortality. Mucocutaneous Candida infections such as thrush and denture stomatitis are associated with local and mechanical factors. A rare and sight-threatening complication of cataract surgery is Candida endophthalmitis. Systemic Candida infections are becoming more common due to increasing use of immunosuppressive drugs and the increasing risk of nosocomial candidiasis in the intensive care unit. Candiduria is increasingly common in older patients with diabetes mellitus, indwelling urinary catheters, and a history of antibiotic therapy.

    Despite therapeutic advances candidiasis remains a common fungal infection most frequently caused by C. albicans and may occur as vulvovaginal candidiasis or thrush, a mucocutaneous candidiasis. Candidiasis frequently occurs in newborns, in immune-deficient people like AIDS patients, and in people being treated with broad spectrum antibiotics. It is mainly due to C. albicans while other species such as C. tropicalis, C. glabrata, C. parapsilosis and C. krusei are increasingly isolated. OTC antifungal dosage forms such as creams and gels can be used for effective treatment of local candidiasis. Whereas, for preventing spread of the disease to deeper vital organs, candidiasis antifungal chemotherapy is preferred. Use of probiotics and development of novel vaccines is an advanced approach for the prevention of candidiasis. Present review summarizes the diagnosis, current status and challenges in the treatment and prevention of candidiasis with prime focus on host defense against candidiasis, advancements in diagnosis, probiotics role and recent progress in the development of vaccines against candidiasis.

    Full Text Available A 59-year-old male patient with jaundice was referred to our hospital because of mass lesions in the pancreatic head and tail. An immunological examination revealed an elevated serum IgG4 level. Computed tomography showed two clear boundary mass lesions in the pancreatic head and tail. Magnetic resonance imaging showed that the mass lesions exhibited low intensity on T1-weighted images and iso-intensity on T2-weighted images. Magnetic resonance cholangiopancreatography showed an obstruction of the main pancreatic duct in the pancreatic head and tail. The possibility of malignant tumors could not be ruled out; therefore, we performed total pancreatectomy. A histopathological examination of the nodular lesions revealed severe lymphoplasmacytic infiltration and inflammatory change around the pancreatic ducts. Immunohistochemistry revealed diffuse infiltration of IgG4-positive plasma cells in the nodules. According to these pathological findings, we diagnosed the patient with IgG4-related multifocal mass lesions of autoimmune pancreatitis (AIP. It is difficult to distinguish between focal type AIP and pancreatic cancer. We herein report a rare case of multifocal mass lesions in AIP and include bibliographical comments.

    Full Text Available Background: Oral candidiasis is a common opportunistic infection of the oral cavity caused by an overgrowth of Candida species, the commonest being Candida albicans. Candida albicans is a harmless commensal organism inhabiting the mouths but it can change into pathogen and invade tissue and cause acute and chronic disease. Dentures predispose to infection with Candida in as many as 65% of elderly people wearing full upper dentures. Purpose: The purpose of this case report is to discuss thrush in patient wearing full denture which rapidly developed. Case: This paper report a case of 57 year-old man who came to the Oral Medicine Clinic Faculty of Dentistry Airlangga University with clinical appearance of pseudomembranous candidiasis (thrush. Case Management: Diagnosis of this case is confirmed with microbiology examination. Patient was wearing full upper dentures, and from anamnesis known that patient wearing denture for 24 hours and he had poor oral hygiene. Patient was treated with topical (nystatin oral suspension and miconazole oral gel and systemic (ketoconazole antifungal. Patient also instructed not to wear his denture and cleaned white pseudomembrane on his mouth with soft toothbrush. Conclusion: Denture, habit of wearing denture for 24 hours, and poor oral hygiene are predisposing factors of thrush and it can healed completely after treated with topical and systemic antifungal.

    Candidais an opportunistic pathogen that causes mucosal and deep systemic candidiasis. The emergence of drug resistance and the side effects of currently available antifungals have restricted their use as long-term prophylactic agents for candidal infections. Given this scenario, probiotics have been suggested as a useful alternative for the management of candidiasis. We analyzed the available data on the efficacy of probiotics in candidal colonization of host surfaces. A number of well-controlled studies indicate that probiotics, particularly lactobacilli, suppressCandidagrowth and biofilm development in vitro.A few clinical trials have also shown the beneficial effects of probiotics in reducing oral, vaginal, and enteric colonization byCandida; alleviation of clinical signs and symptoms; and, in some cases, reducing the incidence of invasive fungal infection in critically ill patients. Probiotics may serve in the future as a worthy ally in the battle against chronic mucosal candidal infections. © The Author 2016.

  16. Wavefront-guided refractive surgery after multifocal lens implantation.

    Science.gov (United States)

    Kuo, Irene C; Reviglio, Victor E

    2009-07-01

    To examine whether wavefront-guided refractive surgery has a role in correcting ametropia after implantation of multifocal intraocular lenses (IOLs). This review begins with an oversight of various multifocal IOLs to help understand how a wavefront might return from the IOL and be captured by an aberrometer. The accuracy of the wavefront may be compromised in eyes with multifocal IOLs by the fact that such lenses provide simultaneous vision--that is, a simultaneous projection of in-focus and out-of-focus images of an object on the retina--and hence returning wavefronts theoretically could be captured in a similar manner by an aberrometer. However, in isolated small series, reproducible wavefront refractions--in which the manifest refraction closely approximates the wavefront refraction and good results after refractive surgery--are attained in eyes with diffractive multifocal IOLs. Small studies suggest that it is possible to perform wavefront-guided excimer light amplification by stimulated emission of radiation (LASER) to correct ametropia following multifocal lens implantation. Larger studies with longer follow-up are needed to determine whether eyes with multifocal lenses derive an added benefit from wavefront-guided refractive surgery over conventional surgery. These studies may help determine whether some IOLs are better suited for subsequent refractive surgery. The age of the patient may affect the outcome of refractive surgery after multifocal IOL implantation.

    2016-01-01

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

    Multifocality and multicentricity are increasingly recognized in breast cancer. However, little is known about the characteristics and biology of these cancers and the clinical implications are controversial. A retrospective, institutional database was used to compare characteristics of multifocal (MF) and multicentric (MC) breast cancers with unifocal (UF) cancers to study concordance of histology and receptor status among primary and secondary foci and to evaluate predictors of lymph node positivity using multivariate logistic regression. Of 1495 invasive cancers, 1231 (82.3 %) were UF, 169 (11.3 %) were MF, and 95 (6.4 %) were MC cancers. When MF and MC cancers were compared with UF cancers, MC but not MF cancers were associated with young age at diagnosis, larger tumor size, lymphovascular invasion, and node positivity. MF but not MC tumors were more likely to be ER/PR+Her2+ tumors and less likely to be triple-negative cancers compared with UF tumors. MF tumors were more likely to be infiltrating ductal carcinomas with an extensive intraductal component, and MC tumors were more likely to be infiltrating lobular carcinomas. Concordance of histology and receptor status between primary and secondary foci was high and was similar for both MF and MC cancers. Multicentricity remained an independent predictor of lymph node positivity on multivariate analysis. MF and MC tumors seem to be biologically different diseases. MC is clinicopathologically more aggressive than MF disease and is more frequently associated with younger age and larger tumor size and also is an independent predictor of node positivity.

Realizaram-se 12 entrevistas em profundidade, revisão documental e análise da produção científica, além das trajetórias dos agentes e seus capitais em 1980 e 2013. Os resultados indicam que a concepção de SBC e SC como ruptura com as práticas de saúde oriundas às “Odontologias Alternativas” prevaleceu entre aqueles com disposições políticas em defesa da democracia e da Reforma Sanitária. Embora a SBC tenha proposta crítica, permanecem antigas “Odontologias” na produção científica e nas práticas de saúde bucal.

    Esophageal candidiasis is one of the most common opportunistic infections in patients infected by human immunodeficiency virus (HIV). This pathology is also found in patients without overt immunodeficiency. Other risk factors are known to be associated with this disease like inhaled or systemic corticosteroid treatment or proton-pump inhibitors and H2 receptor antagonists. In the absence of identified risk factors, a primary immune deficiency should be sought. Prevention of esophageal candidiasis is based primarily on the identification of risk factors, and a better control of them. This article presents a review of the physiopathology, clinical presentation and management of esophageal candidiasis by primary care physicians. We will also discuss ways of preventing esophageal candidiasis when necessary.

    To investigate the clinical and pathological diagnosis of oral candidiasis and reduce misdiagnosis. The medical records of 8 patients with oral candidiasis were reviewed retrospectively, HE and PAS staining of histopathology were applied to study the specimens. It was found that oral candidiasis were identified by pathological diagnosis, but weren't considered clinically. Minor abscesses were all detected in the epithelium of conventional histopathologic sections, the hyphae were shown by PAS staining invading the epithelium. The results suggest that candidal infections should be considered, if there are hyperplastic or ulcerative lesions which last for long time; when minor abscesses are detected in the epithelium by histopathologic examination, oral candidiasis should be highly suspected, and be confirmed by PAS staining.

    Candidia spp. are responsible for contributing to the increasing global prevalence of fungal infections. Fluconazole (Diflucan((R)), Pfizer) is a triazole that has established an exceptional therapeutic record for candida infections including oropharyngeal and esophageal candidiasis, vulvovaginal candidiasis, candidemia and disseminated candidiasis. It is both an oral and parenteral fungistatic agent that inhibits ergosterol synthesis in yeasts. Extensive clinical studies have demonstrated fluconazole's remarkable efficacy, favorable pharmacokinetics and reassuring safety profile, all of which have contributed to its widespread use. Fluconazole became the first antifungal with worldwide sales exceeding billions of dollars, therefore providing an incentive for the pharmaceutical industry to develop new antifungals. This review will examine the contributions and limitations of fluconazole in the treatment of superficial and invasive candidiasis syndromes.

    Autosomal dominant chronic mucocutaneous candidiasis (AD-CMC) is a rare and severe primary immunodeficiency that is characterized by mucocutaneous fungal infection, autoimmunity, cerebral aneurysms, and oropharyngeal and esophageal cancer. Recently, it was discovered that STAT1 mutations are responsible for AD-CMC. These mutations lead to the inability of STAT1 to be dephosphorylated, resulting in hyperphosphorylation, increased binding to the DNA, and gain of function (GOF) effects on STAT1 signaling. Furthermore, a characteristic feature of AD-CMC patients is deficiency in the T-helper 17 (Th17) responses, which is believed to be the immunological cause of the mucocutaneous fungal infection. No targeted treatment other than lifelong antifungal prophylaxis exists for AD-CMC. However, the discovery of the genetic and immunological defects makes it now possible to explore new treatment strategies. This review will discuss immunomodulatory treatment options that can be explored in patients with STAT1 GOF mutations. Copyright © 2016. Published by Elsevier Ltd.

    2003-01-01

    Chronic hyperplastic candidosis/candidiasis (CHC; syn. candidal leukoplakia) is a variant of oral candidosis that typically presents as a white patch on the commissures of the oral mucosa. The major etiologic agent of the disease is the oral fungal pathogen Candida predominantly belonging to Candida albicans, although other systemic co-factors, such as vitamin deficiency and generalized immune suppression, may play a contributory role. Clinically, the lesions are symptomless and regress after appropriate antifungal therapy and correction of underlying nutritional or other deficiencies. If the lesions are untreated, a minor proportion may demonstrate dysplasia and develop into carcinomas. This review outlines the demographic features, etiopathogenesis, immunological features, histopathology, and the role of Candida in the disease process. In the final part of the review, newer molecular biological aspects of the disease are considered together with the management protocols that are currently available, and directions for future research.

La metodología empleada fue el análisis de prácticas discursivas como producción del sentido. El análisis constató que el Reporte Mundial de Salud Bucal no se constituye en una herramienta política-teórica para la satisfacción del derecho a la salud bucal, en razón a que no incorpora el enfoque basado en los derechos humanos. Así pues, la perspectiva de este documento es limitada a los cuidados en salud bucal y no establece mecanismos para el efectivo enfrentamiento de los determinantes sociales y las obligaciones estatales de asegurar el derecho a la salud bucal no son enfatizadas. Asimismo, al alejarse del referencial de los derechos humanos, también se distancia de la bioética, en razón de que el paciente no es considerado en sus múltiples contextos, que permean el proceso salud-enfermedad; así, es contrario a la promoción de condiciones de vidas justas y ecuánimes para los individuos.

    To examine the presence of markers associated with malignancy, including p53, p21 cyclin-dependent kinase inhibitor 1A, murine double minutes-2, and others, in chronic hyperplastic candidiasis. Immunohistochemical methods were used to examine the expression of p53, murine double minutes-2, p21 cyclin-dependent kinase inhibitor 1A, metallothionein, and proliferating cell nuclear antigen in 42 chronic hyperplastic candidiasis lesions and 11 non-infected control tissues. Terminal deoxynucleotidyl transferase-mediated digoxigenin-dUTP nick-end labeling was used to examine apoptosis, which was correlated with p53 expression. These markers were measured in lesions of chronic hyperplastic candidiasis that did not show any epithelial dysplasia or histological signs of malignancy. p53 scores were higher in chronic hyperplastic candidiasis than in controls (P = 0.0046). Murine double-minutes 2 levels were not elevated. p21 cyclin-dependent kinase inhibitor 1A was increased in parabasal (P hyperplastic candidiasis lesions showed a similar basal/parabasal metallothionein staining pattern to that seen in normal squamous epithelium. Proliferating cell nuclear antigen was increased (P = 0.0007), as was apoptosis (P = 0.0033). Increased p53 in oral chronic hyperplastic candidiasis suggests an increased potential for malignant change in the epithelium, above that of normal tissues. Further functional investigation is required, as well as clinical follow-up studies. © 2012 Blackwell Publishing Asia Pty Ltd.

    Pigmented villonodular synovitis (PVNS) is a rare, benign proliferative disease of the synovial tissue that affects a single joint or a tendon sheath. Data from the literature present only a few cases of multifocal PVNS. This paper presents multifocal PVNS in the adult. This disease can affect bilateral shoulders, hips and knees. The diagnosis may be delayed by the slow evolution of the disease (up to ten years); some patients may be seen with late-stage degenerative joints, serious complications, painful and functionally uncompensated, with significant locomotion deficit. PVNS requires a radical treatment with prosthetic arthroplasty associated with synovectomy. Complex imaging (X-Rays, magnetic resonance imaging (MRI), ultrasound) and macroscopic appearance of the lesions during surgery confirms the clinical diagnosis of multifocal PVNS with secondary bone lesions. Histology marks the final diagnosis of multifocal PVNS. The postoperative results are good, with recovery in functional parameters of the joints with endoprosthesis.

    We examined the reliability of multifocal visual evoked potentials for evaluating visual-field defects in a child with epilepsy and an arachnoid cyst. Multifocal visual evoked potentials were measured both when perimetry was difficult and several years later, when kinetic perimetry became possible in a child with epilepsy and homonymous hemianopia, as suggested by computed tomography of the brain. The peak latency and amplitude of response waves were used for assessment. The recordings of multifocal visual evoked potentials at both times revealed marked decreases in amplitude in the left visual hemifield. This area of decreased amplitude corresponded to the location of the lesion observed with imaging techniques, and was consistent with the left homonymous hemianopia observed via kinetic perimetry. The objective evaluation of visual-field defects through multifocal visual evoked potentials may be useful in children in whom conventional perimetry is difficult.

    Multifocal sensory demyelinating neuropathy has not been adequately reported in the literature. A 42-year-old man with numbness of the left hand for 3 years and of the right hand for 6 months had a pure multifocal sensory neuropathy involving both hands, most prominently affecting 2-point discrimination, number writing, and object recognition of the left hand. Near-nerve needle sensory and mixed nerve conduction studies were performed on the left ulnar nerve. Studies of the left ulnar nerve documented a demyelinating neuropathy characterized by temporal dispersion and marked decrease in the amplitudes of the sensory and mixed compound nerve potentials in the above-elbow-axilla segment. With intravenous immunoglobulin treatment, there was improvement in his neuropathic condition. In this study I describe a case of multifocal sensory demyelinating neuropathy as a counterpart of multifocal motor neuropathy. Muscle Nerve 56: 825-828, 2017. © 2016 Wiley Periodicals, Inc.

  20. Multifocal systemic tuberculosis: the many faces of an old nemesis.

    Al-Tawfiq, Jaffar A

    2007-04-01

    Tuberculosis continues to be a major health problem, where an estimated 7-8 million new cases are diagnosed each year. Multifocal tuberculosis is characterized by the presence of large multifocal tuberculous areas in the same or different organs. Difficulty in diagnosis of multifocal tuberculosis and consideration of other diseases may lead to a delay in diagnosing this entity. Here the clinical features and characteristics of three patients with multifocal systemic tuberculosis are described. During the period of 1999-2005, a total of 128 confirmed cases of tuberculosis were identified. Three (2.3%) patients had multifocal systemic tuberculosis. The first case had involvement of the lung, psoas muscle, and the vertebral bodies. The second patient had multiple brain lesions with mediastinal and retroperitoneal lymphadenopathy. The third patient had multiple brain lesions, lymphadenopathy, and colonic lesions initially mimicking a metastatic disease. Mycobacterium tuberculosis was grown from pleural fluid in one patient and from lymph node biopsies in another patient. The third patient had histopathologic evidence of tuberculosis. All patients received standard anti-tuberculous treatment, resulting in a full recovery in two patients, while the third patient had residual weakness. Multifocal systemic tuberculosis may pose a diagnostic challenge and may occur in immunocompetent hosts, in whom this entity generally has a good outcome.

    This paper describes use of Prony's method as a filter applied to multifocal visual-evoked-potential (mfVEP) signals. Prony's method can be viewed as an extension of Fourier analysis that allows a signal to be decomposed into a linear combination of functions with different amplitudes, damping factors, frequencies and phase angles. By selecting Prony method parameters, a frequency filter has been developed which improves signal-to-noise ratio (SNR). Three different criteria were applied to data recorded from control subjects to produce three separate datasets: unfiltered raw data, data filtered using the traditional method (fast Fourier transform: FFT), and data filtered using Prony's method. Filtering using Prony's method improved the signals' original SNR by 44.52%, while the FFT filter improved the SNR by 33.56%. The extent to which signal can be separated from noise was analysed using receiver-operating-characteristic (ROC) curves. The area under the curve (AUC) was greater in the signals filtered using Prony's method than in the original signals or in those filtered using the FFT. filtering using Prony's method improves the quality of mfVEP signal pre-processing when compared with the original signals, or with those filtered using the FFT.

    2015-12-01

    The anti-tumour necrosis factor [TNF] monoclonal antibody, infliximab, is commonly prescribed in both ulcerative colitis and Crohn's disease. Neurological side effects such as optic neuritis are well recognised, although not as frequently seen as hypersensitivity and serious infections. We present a case of peripheral neuropathy in a young man on infliximab therapy for ulcerative colitis. This presented as an asymmetrical and slowly progressive weakness in his right upper limb, severely impacting on function. Investigations confirmed a diagnosis of multifocal motor neuropathy [MMN]. This has been previously described in patients receiving infliximab for rheumatological conditions. The exact mechanism is unclear, but the neuropathy responds well to intravenous immunoglobulin. In our case, infliximab was discontinued. The patient was treated with immunoglobin for 5 days and recovered rapidly. Mercaptopurine was instituted as maintanence therapy, with good effect. Gastroenterologists prescribing infliximab should be cognisant of both peripheral and central neurological complications, ensuring prompt withdrawal of the offending agent and appropriate alternative treatment.

    1987-01-01

    Thirty-nine percent of 1,448 working sheep dogs were affected with varying degrees of multifocal retinal disease on ophthalmoscopic examination. Lesions consisted of localized areas of hyperreflexia in the tapetal fundus, often associated with hyperpigmentation. Severely affected animals had widespread hyperreflexia with retinal vascular attenuation. Only 6% of 125 New Zealand dogs raised in urban environment were similarly affected. Both eyes of 70 dogs from New Zealand were examined histologically. Forty-seven of 70 dogs had ocular inflammatory disease. Ten other dogs had noninflammatory eye disease, and 13 dogs had normal eyes. Histologically, eyes with inflammatory disease were divided into three categories: Dogs 3 years of age or less with active inflammatory disease of the retina, uvea, and vitreous. Four dogs in this group had migrating nematode larvae identified morphologically as genus Toxocara. Diffuse retinitis and retinal atrophy in conjunction with localized retinal necrosis and choroidal fibrosis. Dogs in this category were severely, clinically affected. Chronic, low-grade retinitis with variable retinal atrophy. Most dogs in this category were over 3 years of age, and many were visually functional. The existence of a definable spectrum of morphological changes associated with inflammation, suggests that Toxocara sp. ocular larva migrans may be the cause of a highly prevalent, potentially blinding syndrome of working sheep dogs in New Zealand.

  5. Integrative agnosia following progressive multifocal leukoencephalopathy.

    Science.gov (United States)

    Butter, C M; Trobe, J D

    1994-03-01

    A 43 year-old man with presumed progressive multifocal leukoencephalopathy developed difficulty recognizing objects and faces in the presence of adequate visual acuity and visual fields. His copying and matching of line drawings was intact, suggesting that his agnosia was associative. However, he had difficulty perceiving overlapping forms and drawings of single objects as integrated wholes. Unlike control subjects, he made fewer errors identifying silhouettes compared to line drawings with internal details. These alterations, together with his feature-by-feature descriptions of objects and copying, suggest that his agnosia was due to a disturbance in integrating local form features, as described by Riddoch and Humphreys (1987). This interpretation is supported by the findings that his tactile recognition and semantic and structural knowledge of the objects he could not identify visually were intact. Furthermore, his deficient performance in categorical matching of photographs to objects was dependent upon the perceptual complexity of the photographs. Similar deficits in early form processing described by other investigators are discussed.

  6. Oral candidiasis in children with immune suppression: clinical appearance and therapeutic considerations.

    1999-01-01

    Children and adolescents with immune compromise and suppression are particularly susceptible to the development of oral candidiasis. In fact, oral candidiasis is the most common oral manifestation in HIV-infected children. Oral candidiasis has been linked to a depressed immune system, more rapid progression to AIDS, more advanced stage of disease in AIDS, and decreased survival. Several different forms of candidiasis may be recognized clinically. These forms are 1) pseudomembraneous candidiasis; 2) erythematous (atrophic) candidiasis; 3) papillary hyperplasia; 4) chronic hyperplastic candidiasis; 5) angular cheilitis; and 6) median rhomboid glossitis. Diagnosis of candidiasis is primarily based upon clinical appearance; in some cases, however, exfoliative cytology and/or biopsy of the lesion may be necessary. It is also possible to culture the lesion to determine the specific subtype of candidia and to evaluate the susceptibility of the fungus to specific antifungal agents. Both topical and systemic treatment by antifungal medications are readily available.

    To evaluate the power profile of multifocal contact lenses (CLs) using a new technology based on quantitative deflectometry. The Nimo TR1504 was used to analyze the power distribution of multifocal CLs. The CLs under study were: Air Optix Aqua Multifocal Low, Medium and High Addition and Focus Progressives. Three lenses of each model were considered. All multifocal CLs showed a power profile characterized by a change toward more positive power values when aperture sizes become smaller. The near refractive addition of the lenses under study was +2.61 D, +1.44 D, +1.30 D and +0.30 D for the Focus Progressives, the Air Optix Aqua Multifocal High, Medium Add and Low Add, respectively. The refractive power of the Focus Progressives did not reach the value of the nominal distance power until a radial distance of 0.9 mm from the center of the lens. For the Air Optix Aqua Multifocal Low Add the distance nominal power was reached at a radial distance of 1.5mm from the center of the lens, whereas this occurred at a distance of 1.8mm for the Air Optix Aqua Multifocal Medium and High Add. The relation between the pupil diameter of the patients and the power profile of these CLs has a crucial implication on the final distance correction and near addition that these lenses provide to patients. Practitioners should know the power profile of these CLs and measure the pupil diameter of each patient in different situations in order to carry out a customized fitting.

    The caspofungin clinical trial database offers an opportunity to assess susceptibility results for Candida pathogens obtained from patients with candidiasis and allows for correlations between efficacy outcomes and MICs. Candida isolates have been identified from patients enrolled in four studies of esophageal candidiasis and two studies of invasive candidiasis. The MICs of caspofungin for all baseline isolates were measured at a central laboratory using NCCLS criteria (document M-27A); MICs for caspofungin were defined as the lowest concentration inhibiting prominent growth at 24 h. MICs were then compared to clinical and microbiological outcomes across the two diseases. Susceptibility testing for caspofungin was performed on 515 unique baseline isolates of Candida spp. obtained from patients with esophageal candidiasis. MICs for caspofungin ranged from 0.008 to 4 microg/ml; the MIC50 and MIC90 were 0.5 and 1.0 microg/ml, respectively. Susceptibility testing was also performed on 231 unique baseline isolates of Candida spp. from patients with invasive candidiasis. The majority (approximately 96%) of MICs were between 0.125 and 2 microg/ml, with MIC50 and MIC90 for caspofungin being 0.5 and 2.0 microg/ml, respectively. Overall, caspofungin demonstrated potent in vitro activity against clinical isolates of Candida species. A relationship between MIC for caspofungin and treatment outcome was not seen for patients with either esophageal candidiasis or invasive candidiasis. Patients with isolates for which the MICs were highest (>2 microg/ml) had better outcomes than patients with isolates for which the MICs were lower (<1 microg/ml). Additionally, no correlation between MIC and outcome was identified for specific Candida species.

    Gastrointestinal endoscopy was performed in two bronchial asthma patients using inhaled corticosteroid who complained of odynophagia. The endoscopic finding was high grade with white moss (Grade III) in both patients. Esophageal candidiasis is often recognized in bronchial asthmatic patients receiving long-term fluticasone propionate (FP) dry powder (Diskhaler) inhalation. We therefore examined the complicated context of esophageal candidiasis in patients with long-term FP inhalation. Out of 20 bronchial asthmatic patients who had been using FP inhalation long-term, seven showed signs of esophageal candidiasis. Three patients had mild grade (Grade I), one middle grade (Grade II) and three high grade (Grade III) candidiasis, with a frequency of 35%. This rate is higher than the usual spontaneous occurrence rate of esophageal candidiasis, and it is suggested that inhalation of corticosteroid medication can penetrate into the esophagus after deep inhalation. We tested this hypothesis in two studies. 1) To measure the esophageal concentration of FP, four healthy adults inhaled 200 microg FP once. Right after inhalation, FP concentration in the esophageal washing fluid was 3.3 microg. On another day, 30 minutes after the same dose of inhaled FP, one FP concentration in the esophageal washing fluid was 0.67 microg (immediately laydown), and another was 0.11 microg (remained standing). This indicates that even though FP dissipates quickly, it remains in the esophagus 30 minutes after inhalation. 2) We observed the process in one patient with high grade (Grade III) esophageal candidiasis. The time of inhalation was changed from just after getting up and just before going to bed to before breakfast and before dinner. Under this regimen, the signs of esophageal candidiasis improved from high to middle grade. If asthmatic patients do not go to sleep immediately after FP inhalation, the remaining FP in the esophagus decreases rapidly, thereby decreasing the risk of esophageal

    Infections of the esophagus are rare and most commonly seen in children with immune suppression resulting from malignancy, chronic metabolic or infectious disease, or immunosuppressive drug therapy. An 18-month-old girl on inhaled corticosteroid for bronchial asthma presented with coffee-ground emesis and melena. Upper endoscopy revealed yellow-white plaques scattered over the mucosa of the distal esophagus. Biopsy results showed chronic esophagitis with features of reflux disease. Gram staining of esophageal brushing showed pseudohyphae, and the culture was positive for candida species. The patient was treated with omeprazole 2 mg/kg per day and fluconazole 6 mg/kg per day for three weeks. Immunological workup was normal and she was negative for human immunodeficiency virus. Post treatment endoscopy showed normal appearance of esophageal mucosa and normal histology. At 12 months after treatment, the child remained asymptomatic and continued to thrive. We believe that this child developed esophageal candidiasis secondary to long-term use of inhaled corticosteroid associated with immune suppression on a background of reflux esophagitis. Anti-acid and antifungal therapies are effective in the treatment.

  13. Insights from human studies into the host defense against candidiasis.

    Candida spp. are the most common cause of mucosal and disseminated fungal infections in humans. Studies using mutant strains of mice have provided initial information about the roles of dectin-1, CARD9, and Th17 cytokines in the host defense against candidiasis. Recent technological advances have resulted in the identification of mutations in specific genes that predispose humans to develop candidal infection. The analysis of individuals with these mutations demonstrates that dectin-1 is critical for the host defense against vulvovaginal candidiasis and candidal colonization of the gastrointestinal tract. They also indicate that CARD9 is important for preventing both mucosal and disseminated candidiasis, whereas the Th17 response is necessary for the defense against mucocutaneous candidiasis. This article reviews the recent studies of genetic defects in humans that result in an increased susceptibility to candidiasis and discusses how these studies provide new insight into the host defense against different types of candidal infections.

    Candidiasis is the most common opportunistic yeast infection. Candida species and other microorganisms are involved in this complicated fungal infection, but Candida albicans continues to be the most prevalent. In the past two decades, it has been observed an abnormal overgrowth in the gastrointestinal, urinary and respiratory tracts, not only in immunocompromised patients, but also related to nosocomial infections and even in healthy individuals. There is a widely variety of causal factors that contribute to yeast infection which means that candidiasis is a good example of a multifactorial syndrome. Due to rapid increase in the incidence in these infections, this is the subject of numerous studies. Recently, the focus of attention is the treatment and, above all, the prevention of those complications. The diagnosis of candidiasis could become quite complicated. Prevention is the most effective "treatment," much more than eradication of the yeast with antifungal agents. There are several aspects to consider in the daily routine that can provide a strength protection. However, a therapeutic approach is necessary when the infection is established, and therefore, other alternatives should be explored. This review provides an overview on predisposition factors, prevention and diagnosis of candidiasis, highlighting alternative approaches for candidiasis treatment.

    A total of 84 HIV-infected homosexual men having either normal oral mucosa (NOM), erythematous candidiasis (EC) or pseudomembranous candidiasis (PsC) were included in the study. The patients were evaluated by median number of peripheral CD4+ cells, CD8+ cells and by lymphocyte function assessed by poke-weed mitogen test. There was a significant difference between CD4+ counts among patients with the two subtypes of candidiasis (95% CI of median difference: 10-240/mm3; P = 0.03), but not for pokeweed mitogen response. Survival analysis showed that after 2 y there was no significant difference in development of AIDS between patients with EC and PsC (P = 0.29). If patients with both types of oral candidiasis were pooled and compared with patients with NOM, a significant difference in development of AIDS was found (P = 0.04). It is concluded that HIV-infected patients with oral candidiasis of any subtype (EC or PsC) are significantly more immune suppressed and show a faster development of AIDS than HIV-infected patients with NOM. However, in this cohort, EC and PsC are of equal importance as predictors for immune suppression and AIDS development.

    Candida albicans causes mucosal and disseminated candidiasis, which represent serious problems for the rapidly expanding immunocompromised population. Until recently, Th1-mediated immunity was thought to confer the primary protection, particularly for oral candidiasis. However, emerging data indicate that the newly-defined Th17 compartment appears to play the predominant role in mucosal candidiasis. PMID:20381638

    Full Text Available Comparação entre a presença de leveduras de Candida na cavidade bucal de crianças sem e com síndrome de Down mostrou-se estatisticamente significante no caso de crianças afetadas por esta cromossomopatia, tornando-as mais predispostas à candidíase bucal, provavelmente favorecida pelas alterações anátomo-fisiológicas da boca em decorrência da trissomia do cromossomo 21. Recidivas constantes de candidíase bucal em crianças portadoras desta alteração cromossômica levou a busca de prováveis alternativas terapêuticas. Visando determinar a atividade antifúngica de Streptomyces sp isolados de diferentes solos brasileiros, 5 cepas foram testadas frente a Candida albicans, oriundas da cavidade bucal de crianças com síndrome de Down. Observou-se que os isolados apresentaram uma diversidade de tamanho dos halos (9-31mm de diâmetro de inibição de crescimento das leveduras, sugerindo uma possível utilização em terapêutica antifúngica.Comparison of the presence of Candida yeasts in the buccal cavity of children without and with Down's syndrome showed a statistically significant difference in the case of children that were affected by this chromosomopathy, rendering them more predisposed to buccal candidiasis, probably due to anatomicophysiologic alterations of the mouth resulting from trisomy of chromosome 21. Constant recurrence of buccal candidiasis in children with this chromosomal alteration lead to the search for a possible therapeutic alternative. Seeking to determine the antifungal activity of Streptomyces sp isolated from various Brazilian soils, 5 strains have been tested for Candida albicans isolated from the buccal cavity of children with Down's syndrome. It was observed that the isolate presented a diversity in the size of the halos (9-31mm in diameter of growth inhibition of the yeasts, suggesting a possible use as a therapeutic antifungal.

    To compare the effect of monovision correction and multifocal intraocular lens (IOL) implantation on patient satisfaction, spectacle dependence, visual acuity, and dysphotopsia in cataract patients. University Hospital of Alexandroupolis, Democritus University of Thrace, Alexandroupolis, Greece. Prospective randomized trial. Patients with a diagnosis of senile cataract with stage 2 nuclear opalescence were randomly assigned to 2 groups: monovision and multifocal IOL implantation. Uncorrected (UDVA) and corrected (CDVA) distance visual acuity, Visual Function Index-14 (VF-14) scores, and spectacle dependence were assessed prior to surgery and 6 months postoperatively. The monovision group comprised 38 patients and the multifocal IOL implantation group, 37 patients. Both techniques provided excellent refractive outcomes in UDVA and VF-14 scores (all P < .01). No significant intergroup differences were detected in VF-14 scores at the final postoperative examination. The monovision group patients presented significantly more spectacle dependence for near vision but less glare. Monovision and multifocal IOL implantation provided excellent refractive outcomes for distance vision. Multifocal IOL insertion was associated with less dependence on glasses overall but significantly more dysphotopsia.

    Full Text Available The incidence of multifocal atrial tachycardia (MAT is very low and accounts for less than 1% of supraventricular tachycardia in infants and children. In this report, the clinical characteristics, medical treatment and outcome of MAT in 2 children are described. The first patient presented with tachycardia and respiratory failure since the day after birth. First, he received amiodarone, propranolol, and digoxin and then amiodarone alone. The heart rhythm converted to sinus rhythm 2 weeks after hospitalization. Although nonsustained MAT was occasionally observed when the infant suffered from pulmonary infection, the frequency of recurrent MAT decreased as the infant grew up. The second patient was a 5-year-old girl. She had congenital heart disease with double outlets of right ventricle (DORV, patent ductus arte-riosus, coarctation of aorta, and ventricular and atrial septal defects. She underwent total correction at the age of 4 years. MAT was noted 3 months after the operation with the presentation of congestive heart failure. The heart rate slowed down and returned to normal sinus rhythm within several hours after amiodarone use. The symptoms and signs of congestive heart failure also disappeared. The patient took amiodarone regularly, and no tachycardia was detected during the follow-up period. MAT is considered to be a relatively benign arrhythmia with likely good outcome if there is no severe underlying illness. It can be well controlled under appropriate drugs, and a long period of follow-up is suggested. If pharmacologic intervention is required, we suggest that amiodarone may be an excellent choice.

    Full Text Available Candidiasis is the second most common vaginal infection. Given the frequent recurrence of the disease, many women tend to use herbal remedies. Thus, the present study aimed to review the association between vaginal candidiasis and herbal medicines in Iran. In this review, we retrieved articles published from 2001 to 2016. Then, the results were expressed both quantitatively and qualitatively. In this study, nine articles were reviewed, which had investigated thyme, garlic, garlic-thyme, olive oil, propolis, myrtus, Nigella sativa (black cumin, and Bunium perscicum boiss (black zira. Subsequently, each of these plants was thoroughly dealt with. The studies on black cumin, garlic, and thyme reported positive effects for these herbs, and they were widely produced for therapeutic purposes. In addition, myrtus was found to have a salutary impact on vaginal candidiasis.

  2. Use of Recombinant Antigens for the Diagnosis of Invasive Candidiasis

    Full Text Available Invasive candidiasis is a frequent and often fatal complication in immunocompromised and critically ill patients. Unfortunately, the diagnosis of invasive candidiasis remains difficult due to the lack of specific clinical symptoms and a definitive diagnostic method. The detection of antibodies against different Candida antigens may help in the diagnosis. However, the methods traditionally used for the detection of antibodies have been based on crude antigenic fungal extracts, which usually show low-reproducibility and cross-reactivity problems. The development of molecular biology techniques has allowed the production of recombinant antigens which may help to solve these problems. In this review we will discuss the usefulness of recombinant antigens in the diagnosis of invasive candidiasis.

    The most serious complication of Paget's disease is sarcomatous degeneration of pagetic bone. Multifocal sarcomatous degeneration occurs mainly in polyostotic Paget's disease. Multifocal Paget's sarcoma is uncommon and can arise in any site. We report two cases of synchronous multifocal sarcomatous degeneration. The two patients were elderly women (aged 77 and 86 years, respectively) who developed sarcomatous lesions concomitantly, in the first case report in left ilium, left tibia, and first lumbar vertebra and in the second case report in the skull, right ilium, and sacrum. Whether these cases are due to the simultaneous development of several primaries or to metastases from a single primary remains unclear. (orig.)

    Invasive candidiasis is a leading infectious cause of morbidity and mortality in premature infants. Improved recognition of modifiable risk factors and antifungal prophylaxis have contributed to the recent decline in the incidence of this infection among infants. Invasive candidiasis typically occurs in the first six weeks of life and presents with non-specific signs of sepsis. Definitive diagnosis relies on growth of Candida in blood culture or cultures from other normally sterile sites, but this may identify fewer than half of cases. Improved diagnostics are needed to guide initiation of antifungal therapy in premature infants. PMID:25677999

    FKS mutant Candida isolates were recovered from 24% (6/25) of abdominal candidiasis patients exposed to echinocandin. Candida glabrata (29%) and Candida albicans (14%) mutants were identified. Multidrug-resistant bacteria were recovered from 83% of FKS mutant infections. Mutations were associated with prolonged echinocandin exposure (P = 0.01), breakthrough infections (P = 0.03), and therapeutic failures despite source control interventions (100%).

Lenses tested included an aspheric monofocal and two apodized diffractive multifocal IOLs with slightly different design parameters. A total of 94 patients were evaluated.Results: Subjects with the ReSTOR® +2.5 D IOL had better near and intermediate vision than those subjects with a monofocal IOL. Intermediate vision was similar to, and near vision slightly lower than, that of subjects with a ReSTOR® +3.0 D IOL implanted. The preferred reading distance was slightly farther out for the +2.5 D relative to the +3.0 D lens, and farthest for the monofocal. Visual acuity at the preferred reading distance was equal with the two multifocal IOLs and significantly worse with the monofocal IOL. Quality of vision measures were highest with the monofocal IOL and similar between the two multifocal IOLs.Conclusion: The data indicate that the ReSTOR +2.5 D IOL provided good intermediate and functional near vision for patients who did not want to accept a higher potential for visual disturbances associated with the ReSTOR +3.0 D IOL, but wanted more near vision than a monofocal IOL generally provides. Quality of vision was not significantly different between the multifocal IOLs, but patient self-selection for each lens type may have been a factor.Keywords: multifocal IOL, near vision, cataract, presbyopia

    The aim of the present project was to investigate accommodative behavior in young adults and adolescents fitted with an aspheric multifocal (center distance) contact lens with focus on evaluating whether these lenses can be an alternative treatment for subjects in which a reduced level of blur and thereby accommodation in near vision is aimed at. Twenty normal subjects aged between 21 and 35 years participated in the study. Aberrometry was perfomed using a Zywave™ aberrometer, first on the uncorrected eyes of all subjects, and again while the subjects wore a multifocal contact lens with a +1.00 add. A Shin-Nippon N Vision-K 5001 Autoref-Keratometer was used to measure accommodative response with two different refractive corrections: (1) habitual spectacle correction only, and (2) habitual correction and a aspheric multifocal (center distance) contact lens. Four hours of adaptation to the lens was allowed. The lag when wearing only the habitual spectacles was compared with the lag while wearing both the habitual spectacles and the aspheric multifocal contact lens. The mean lag of accommodation for the subject group was 0.85 D (±0.57 SD) and 0.75 D (±0.52 SD) without and with the multifocal lens, respectively. Statistical analyses showed no difference in lag (t = 0.8479, p = 0.407) with and without the lens. In conclusion, young normal subjects do not relax accommodation when fitted with aspheric multifocal center distance lenses when the addition is +1.00. It is therefore unlikely that subjects with accommodative ability, in whom the treatment purpose is to reduce blur and thereby accommodation, can be effectively treated with such lenses.

    2017-09-01

    Manufacturing methods and design features of modern diffractive-refractive intraocular lenses are discussed. The implantation of multifocal intraocular lenses is the most optimal method of restoring the accommodative ability of the eye after removal of the natural lens. Diffractive-refractive intraocular lenses are the most widely used implantable multifocal lenses worldwide. Existing methods for manufacturing such lenses implement various design solutions to provide the best vision function after surgery. The wide variety of available diffractive-refractive intraocular lens designs reflects the demand for this method of vision correction in clinical practice and the importance of further applied research and development of new technologies for designing improved lens models.

    Full Text Available Primary open angle glaucoma is a chronic and progressive optic neuropathy. It can lead to serious damage of visual impairment, and it is an important eye disease of blindness. Multifocal electroretinogram is a new way to measure visual electrophysiology. It can measure electroretinogram of the whole visual field of many small parts in a relatively short period of time, and it can reflect the function of regional retina. It has an extremely important value for early diagnosis of primary open angle glaucoma. The research advances on multifocal electroretinogram in diagnosing primary open angle glaucoma were summarized in this paper.

    Candidiasis is commonly observed in patients with primary sclerosing cholangitis (PSC), but the clinical risk factors associated with its presence have not been fully investigated. In this study, we aimed to analyse the incidence, risk factors, and transplantation-free survival in primary sclerosing cholangitis (PSC) patients with persistent biliary candidiasis. We retrospectively analysed patients diagnosed with PSC who were admitted to our department during 2002 to 2012. One-hundred fifty patients whose bile cultures were tested for fungal species were selected, and their clinical and laboratory parameters were investigated. The results of endoscopic retrograde cholangiography (ERC) and bile cultures were analysed using chart reviews. The cases of biliary candidiasis were sub-classified as transient or persistent. Thirty out of 150 (20.0%) patients had biliary candidiasis. Although all patients demonstrated comparable baseline characteristics, those with biliary candidiasis showed significantly reduced transplantation-free survival (p candidiasis. A subgroup analysis showed reduced survival with a greater necessity for orthotopic liver transplantation (OLT) only in patients with persistence of Candida (p = 0.007). The survival in the patients with transient biliary candidiasis was comparable to that in candidiasis-free patients. In a multivariate regression analysis that included Mayo risk score (MRS), sex, age, dominant stenosis, inflammatory bowel disease, autoimmune hepatitis overlap syndrome, and number of times ERC was performed, biliary candidiasis was an independent risk factor for reduced survival (p = 0.008). Risk factors associated with acquisition of biliary candidiasis were age at PSC diagnosis and number of ERCs. The persistence of biliary candidiasis is associated with markedly reduced transplantation-free survival in PSC patients. By contrast, actuarial survival in patients with transient biliary candidiasis approaches that for patients without any

    Although oropharyngeal candidiasis is associated with inhaled corticosteroid (ICS) usage, there is sparse data on the prevalence of posterior pharyngeal candidiasis in those without any detectable oral candidiasis on clinical examination. We systematically investigated the relationship between oral candidiasis on clinical examination and the presence of posterior pharyngeal candidiasis at bronchoscopy. We conducted a cross-sectional study on a convenience sample of 100 patients undergoing bronchoscopy at our institution. Patients were assessed for symptoms of and risk factors for candida infection and had an examination of their oropharynx for evidence of candidiasis before bronchoscopy. They subsequently had a detailed assessment for posterior candidiasis at bronchoscopy. We performed a posteriori subgroup analysis, which focused solely on those patients on ICS maintenance therapy. Median age was 54.7 (27-84) years, and 55 patients were male; 47 % of patients were on ICS, and 20 % of this cohort received recent oral corticosteroids. Twenty-eight percent of this convenience sample had posterior pharyngeal candidiasis; however, only 10.7 % (3/28) of these patients had clinically detectable oral candidiasis on clinical examination before bronchoscopy. Factors that were independently associated with the presence of pharyngeal candidiasis at bronchoscopy were OR (95 % CI) ICS usage 6.9 (2.5-19.2), particularly fluticasone usage 6.8 (2.62-17.9) and the presence of dysphonia 3.2 (1.3-8.0). In the subgroup analysis of ICS usage, posterior pharyngeal candidiasis was correlated with the presence of dysphonia but was not independently associated with fluticasone or budesonide dosage. This study demonstrates that posterior pharyngeal candidiasis in the absence of clinically overt oral candidiasis is frequent amongst ICS users. A history of ICS use, particularly fluticasone usage, as well as the presence of dysphonia are associated with posterior pharyngeal candidiasis at

Two patients underwent uncomplicated DSAEK by 2 corneal surgeons at different surgery centers but with tissue from the same donor and were referred to the Bascom Palmer Eye Institute with multifocal infiltrates at the graft-host cornea interface 6 to 8 weeks later, and anterior chamber cultures that were positive for the same genetic strain of C. albicans. Immediate explantation of DSAEK lenticules and daily intracameral and instrastromal voriconazole and amphotericin injections failed to control the infection. Thus, both patients underwent therapeutic penetrating keratoplasty with intraocular lens explantation, pars plana vitrectomy, and serial postoperative intraocular antifungal injection. Both patients are doing well at 2 years postoperatively with best-corrected vision of 20/20 and 20/30+ with rigid gas permeable lenses. One patient required repeat optical penetrating keratoplasty and glaucoma tube implantation 1 year after the original surgery. Literature review reveals that donor lenticule explantation and intraocular antifungals are often inadequate to control fungal interface keratitis, and a therapeutic graft is commonly needed. Interface fungal keratitis and endophthalmitis due to infected donor corneal tissue is difficult to treat, and both recipients of grafts originating from the same donor are at risk of developing this challenging condition.

    Ericson, Jessica E.; Benjamin, Daniel K.

    2014-01-01

    Purpose of review Invasive candidiasis is a serious infection in hospitalized infants that results in significant mortality and morbidity. Fluconazole is approved by the U.S. Food and Drug Administration for prophylaxis of invasive candidiasis in patients undergoing bone marrow transplantation but is not approved for use in infants. This review will describe the history of fluconazole use for prophylaxis in infants. Recent findings Limiting fluconazole prophylaxis to infants with risk factors, in addition to low birth weight and early gestational age, reduces the number of infants treated with fluconazole and the duration of fluconazole therapy for each infant. Summary Fluconazole prophylaxis appears to be safe for use in premature infants. Reduction in the incidence of invasive candidiasis is observed even when prophylaxis is limited to infants with multiple risk factors. Centers with a low incidence of invasive candidiasis may not benefit from fluconazole prophylaxis. Significant short- and long-term toxicity and increases in fluconazole-resistant organisms have not been observed with fluconazole use in the intensive care nursery. PMID:24626156

    Over the last few decades, inhaled corticosteroids (ICs) became the cornerstone in the treatment of persistent asthma. Their use improved asthma control, decreased mortality and also minimized adverse reactions associated with systemic steroid. Esophageal candidiasis is a rare complication resulting from the use of ICs. Although, in recent years, as their prescriptions has increased, more cases have been reported, especially in Japan. Listed are 4 case reports regarding esophageal candidiasis in asthmatic patients associated with inhaled budesonide administration. In the cases reported herein, the use of a different device of dry powder budesonide might have favored esophageal drug deposition and Candida infection. Patients denied using systemic corticosteroids in the previous 6 months. Furthermore, none of the patients presented Diabetes mellitus, malignant disease, HIV infection, or other immunosuppressive conditions. We conclude that patients treated with high doses of ICs are at higher risk of developing esophageal candidiasis. These patients should undergo upper gastrointestinal endoscopy whenever they present symptoms. Nevertheless, we must keep in mind that infection might also be asymptomatic and esophageal candidiasis prevalence may be higher than that reported thus far.

    We studied the prevalence of fluconazole resistance in esophageal candidiasis. Patients with suspected esophageal candidiasis during gastroscopy underwent culture of white plaques. Minimum inhibitory concentration (MIC) >64 μg/mL of fluconazole for Candida was indicative of resistance. Sensitivity of itraconazole was tested in a subset of resistant strains. Sixty-five patients were included. Mean (SD) age was 50.03 (13.5) years and 67.7 % were males. Predisposing factors for candidiasis were found in 42 (64.6 %) patients. C. albicans was identified in 64 (97.4 %) patients and C. glabrata in one patient. Fluconazole resistance was seen in 38 (59.4 %) patients with C. albicans and also in the one patient with C. glabrata. All the fluconazole resistant isolates of C. albicans had MIC >128 μg/mL suggesting very high resistance. Twelve patients with fluconazole resistance had itraconazole resistance as well. The study shows a high rate of fluconazole resistance in patients with esophageal candidiasis.

    2017-07-01

    The widespread implementation of immunosuppressants, immunomodulators, hematopoietic stem cell transplantation and solid organ transplantation in clinical practice has led to an expanding population of patients who are at risk for invasive candidiasis, which is the most common form of fungal disease among hospitalized patients in the developed world. The emergence of drug-resistant Candida spp. has added to the morbidity associated with invasive candidiasis and novel therapeutic strategies are urgently needed. Areas covered: In this paper, we explore investigational agents for the treatment of invasive candidiasis, with particular attention paid to compounds that have recently entered phase I or phase II clinical trials. Expert opinion: The antifungal drug development pipeline has been severely limited due to regulatory hurdles and a systemic lack of investment in novel compounds. However, several promising drug development strategies have recently emerged, including chemical screens involving Pathogen Box compounds, combination antifungal therapy, and repurposing of existing agents that were initially developed to treat other conditions, all of which have the potential to redefine the treatment of invasive candidiasis.

    The purpose of this multicentre study was to determine the incidence of oral candidiasis in patients treated with topical steroids for oral lichen planus (OLP) and to determine whether the application of a concurrent antifungal therapy prevented the development of an oral candidiasis in these patients. Records of 315 patients with OLP seen at four Oral Medicine practices treated for at least 2 weeks with steroids with and without the use of an antifungal regimen were retrospectively reviewed. The overall incidence of oral fungal infection in those treated with steroid therapy for OLP was 13.6%. There was no statistically significant difference in the rate of oral candidiasis development in those treated with an antifungal regimen vs those not treated prophylactically (14.3% vs 12.6%) (P = 0.68). Despite the use of various regimens, none of the preventive antifungal strategies used in this study resulted in a significant difference in the rate of development of an oral candidiasis in patients with OLP treated with steroids. © 2015 John Wiley & Sons A/S.

    2004-10-01

    Oropharyngeal and esophageal candidiases remain significant causes of morbidity in human immunodeficiency virus (HIV)-infected patients, despite the dramatic ability of antiretroviral therapy to reconstitute immunity. Notable advances have been achieved in understanding, at the molecular level, the relationships between the progression of HIV infection, the acquisition, maintenance, and clonality of oral candidal populations, and the emergence of antifungal resistance. However, the critical immunological defects which are responsible for the onset and maintenance of mucosal candidiasis in patients with HIV infection have not been elucidated. The devastating impact of HIV infection on mucosal Langerhans' cell and CD4(+) cell populations is most probably central to the pathogenesis of mucosal candidiasis in HIV-infected patients. However, these defects may be partly compensated by preserved host defense mechanisms (calprotectin, keratinocytes, CD8(+) T cells, and phagocytes) which, individually or together, may limit Candida albicans proliferation to the superficial mucosa. The availability of CD4C/HIV transgenic mice expressing HIV-1 in immune cells has provided the opportunity to devise a novel model of mucosal candidiasis that closely mimics the clinical and pathological features of candidal infection in human HIV infection. These transgenic mice allow, for the first time, a precise cause-and-effect analysis of the immunopathogenesis of mucosal candidiasis in HIV infection under controlled conditions in a small laboratory animal.

    2017-11-14

    Our objective is to describe a multifocal vitelliform presentation of Best's disease. The lesions in this disease may vary in size and shape, some may be a disc diameter in size, and often have some irregularity in their contour. The case is described of a 21-year-old male patient referred to our ophthalmology department due to a progressive loss of vision. His poor visual acuity was confirmed, and a complete examination was performed, in which macular flecks were observed, with yellow pigment arranged in oval distribution near their periphery. Due to the suspicion of Best's multifocal disease, genetic tests were performed. Multifocal vitelliform disease with the same features as those in Best's disease occurs most frequently in patients with a normal electro-oculogram (EOG), and a normal family history. Best's multifocal disease must be suspected in case of multiple vitelliruptive lesions close to the posterior pole. Genetic testing is essential for its diagnosis.

    Purpose To describe peripheral defocus when myopic eyes are corrected with spherical and center-distance multifocal soft contact lenses while looking at distance and near. Methods Twenty-five young adults with spherical contact lens-corrected refractive error of −0.50 to −6.00 D participated. Refractive error of each participant’s right eye was measured while it wore a spherical soft contact lens (Biofinity) and again while it wore a center-distance multifocal soft contact lens with a +2.50-D add (Biofinity Multifocal "D"). Measurements were made centrally and along the horizontal meridian at ±20°, ±30°, and ±40° from the line of sight at distance and near (3.33-D demand). Results The mean (±SD) age and spherical equivalent refractive error were 23.8 ± 1.3 years and −3.62 ± 1.56 D, respectively. At distance, the multifocal contact lens resulted in significantly more myopic defocus than the spherical contact lens at the 40° and 30° locations on the nasal retina and at the 20° and 30° locations on the temporal retina (pcontact lens in this study make it a good candidate for studies seeking to examine the effect of peripheral myopic defocus on myopia progression in children.

Multiple optic (multifocal IOLs are available which claim to allow good vision at a range of distances. It is unclear whether this benefit outweighs the optical compromises inherent in multifocal IOLs. OBJECTIVES: The objective of this review was to assess the effects of multifocal IOLs, including effects on visual acuity, subjective visual satisfaction, spectacle dependence, glare and contrast sensitivity, compared to standard monofocal lenses in people undergoing cataract surgery. METHODS: Search methods: We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register, The Cochrane Library 2012, Issue 2, MEDLINE (January 1946 to March 2012, EMBASE (January 1980 to March 2012, the metaRegister of Controlled Trials (mRCT (www.controlled-trials.com, ClinicalTrials.gov (www.clinicaltrials.gov and the WHO International Clinical Trials Registry Platform (ICTRP (www.who.int/ictrp/search/en. We did not use any date or language restrictions in the electronic searches for trials. The electronic databases were last searched on 6 March 2012. We searched the reference lists of relevant articles and contacted investigators of included studies and manufacturers of multifocal IOLs for information about additional published and unpublished studies. Selection criteria: All randomised controlled trials comparing a multifocal IOL of any type with a monofocal IOL as control were included. Both unilateral and bilateral implantation trials were included. Data collection and analysis: Two authors collected data and assessed trial quality. Where possible, we pooled data from the individual studies using a random-effects model, otherwise we tabulated data. MAIN RESULTS: Sixteen completed trials

    Esophageal candidiasis is often observed in patients with risk factors for its development and fluconazole is the therapeutic choice for the treatment of this disease. To determine its frequency, by performing upper digestive endoscopy; to determine Candida species involved in its pathogenesis and verify their distribution according with the predisposing factors and to determine susceptibility to fluconazole in the samples. From March 2006 to April 2007, all patients submitted to esophagogastroduodenoscopy at the Digestive Endoscopy Unit in the Oswaldo Cruz University Hospital, Recife, PE, Brazil, were eligible for the study. Samples were collected from patients who presented lesions consistent with esophageal candidiasis in order to identify Candida species and verify their susceptibility to fluconazole. The predisposing factors for the occurrence of esophageal candidiasis were described. Of 2,672 patients referred to upper endoscopy at the Digestive Endoscopy Unit, 40 (1.5%) had endoscopic findings compatible with esophageal candidiasis. The average age was 49.1 years. Twenty one patients (52.5%) were less than 50 years old, of which 82.6% were infected with HIV. Most of them (52.5%) were males and 65.0% were inpatients. Diseases were identified in 90% of the patients and 21 (52.5%) were HIV positive. Concerning endoscopic findings, severe forms of esophagitis were found in 50% of the patients with CD4 count Esophageal candidiasis prevalence was low, although within the results described by other authors. Male and inpatients were the most affected. The species isolated varied according to the characteristics of each group studied. Both, resistance and dose-depending susceptibility to fluconazole were considered high.

    To evaluate and compare the visual performance of two simultaneous vision multifocal contact lenses (CLs). In this cross-over study design 20 presbyopic subjects were fitted with two different simultaneous vision multifocal CLs (the PureVision Multifocal Low Add and Acuvue Oasys for Presbyopia) in random order. After 1 month, binocular distance visual acuity (BDVA) under photopic (85 cd/m(2)) and mesopic (3 cd/m(2)) conditions, binocular near visual acuity (BNVA), binocular distance contrast sensitivity function (CSF) under photopic and mesopic conditions, binocular near CSF and defocus curve were measured. Subjects were then refitted with the alternative correction and the procedure was repeated. Mean BDVA under photopic conditions was similar for the Acuvue Oasys for Presbyopia and PureVision Multifocal Low Add: 0.01 ± 0.08 and 0.00 ± 0.08 logMAR, respectively (P = 0.45). Under mesopic conditions the values of BDVA were 0.20 ± 0.58 and 0.11 ± 0.09 logMAR, respectively (P = 0.005). Mean BNVA was 0.20 ± 0.05 and 0.15 ± 0.08 logMAR for the Acuvue Oasys and PureVision Low Add, respectively (P = 0.06). Binocular distance CSF testing revealed no statistically significant differences between lenses under photopic, mesopic or near conditions. Both lenses provided a comparable intermediate visual acuity. Both simultaneous vision multifocal CLs provided adequate distance visual quality under photopic and mesopic conditions, and better visual acuity was provided under mesopic conditions for the Purevision lens. Both lenses provided adequate visual performance at intermediate distance, but the near visual acuity appears to be insufficient for early presbyopes who require a moderately demanding near visual quality.

    The purpose of this study was to investigate the optical zone power profile of the most commonly prescribed soft contact lenses to assess their potential impact on peripheral refractive error and hence myopia progression. The optical power profiles of six single vision and ten multifocal contact lenses of five manufacturers in the powers -1.00 D, -3.00 D, and -6.00 D were measured using the SHSOphthalmic (Optocraft GmbH, Erlangen, Germany). Instrument repeatability was also investigated. Instrument repeatability was dependent on the distance from the optical centre, manifesting unreliable data for the central 1mm of the optic zone. Single vision contact lens measurements of -6.00 D lenses revealed omafilcon A having the most negative spherical aberration, lotrafilcon A having the least. Somofilcon A had the highest minus power and lotrafilcon A the biggest deviation in positive direction, relative to their respective labelled powers. Negative spherical aberration occurred for almost all of the multifocal contact lenses, including the centre-distance designs etafilcon A bifocal and omafilcon A multifocal. Lotrafilcon B and balafilcon A seem to rely predominantly on the spherical aberration component to provide multifocality. Power profiles of single vision soft contact lenses varied greatly, many having a negative spherical aberration profile that would exacerbate myopia. Some lens types and powers are affected by large intra-batch variability or power offsets of more than 0.25 dioptres. Evaluation of power profiles of multifocal lenses was derived that provides helpful information for prescribing lenses for presbyopes and progressing myopes.

    Full Text Available Diabetic neuropathy is the most common neuropathy in industrialized countries, with a remarkable range of clinical manifestations. The vast majority of the patients with clinical diabetic neuropathy have a distal symmetrical form that progress following a fiber-length dependent pattern, with predominant sensory and autonomic manifestations. This pattern of neuropathy is associated with a progressive distal axonopathy. Patients are exposed to trophic changes in the feet, pains and autonomic disturbances. Less often, diabetic patients may develop focal and multifocal neuropathy that includes cranial nerve involvement, limb and truncal neuropathies. This neuropathic pattern tends to occur after 50 years of age, mostly in patients with longstanding diabetes mellitus. The LDDP does not show any trend to improvement and either relentlessly progresses or remain relatively stable over years. Conversely the focal diabetic neuropathies, which are often associated with inflammatory vasculopathy on nerve biopsies, remain self limited, sometimes after a relapsing course.A neuropatia diabética é a mais predominante das neuropatias nos países industrializados apresentando uma gama variável de manifestações clinicas. A maioria dos pacientes com neuropatia diabética apresenta uma forma simétrica distal que progride para um padrão fibra comprimento dependente com manifestações sensitivas e autonomicas. Este tipo de neuropatia é associado com uma axonopatia distal progressiva. Os pacientes apresentam modificações tróficas nos pés, dores e distúrbios autonômicos. Menos freqüentemente os pacientes diabéticos podem desenvolver neuropatia focal e multifocal que incluem envolvimento de nervos cranianos, tronco e membros inferiores. Este padrão de neuropatia é mais freqüente em pacientes com mais de 50 anos e com longa historia de diabetes. Este tipo de neuropatia fibra-comprimento dependente não apresenta melhora, progride lentamente ou

    To describe the most pertinent echographic findings regarding systemic and renal candidiasis in high-risk neonates. Echographic findings and clinical histories of 40 neonates in the neonatal intensive care unit were retrospectively analyzed. Thirty-eight presented systemic candidiasis with renal participation, while two showed only renal candidiasis. Ultrasound scans were performed using 7.5 MHz probes. Alterations in renal echo structure, presence of echogenic material without acoustic shadowing in the excretory system (mycetoma), presence of lithiasis, pyonephrosis and associated renal malformations were all evaluated. Ten patients presented renal alterations in ultrasound scan. Six children had originally shown increased eye-catching in the renal parenchyma which was resolved after medical treatment. Four children presented renal mycetoma, and in two there were renal malformations. Both of these exhibited a profile for pyonephrosis. One patient with renal mycetoma without urological abnormalities developed a lithiasis. Surgical intervention was unnecessary in all cases. The most common echographic findings in immature high-risk low-weight patients with systemic and renal candidiasis were alterations in the eye-catching of renal parenchyma and the presence of mycetoma.

    Interleukin 12Rβ1 (IL-12Rβ1)-deficient patients are prone to clinical disease caused by mycobacteria, Salmonella, and other intramacrophagic pathogens, probably because of impaired interleukin 12-dependent interferon γ production. About 25% of patients also display mucocutaneous candidiasis, probably owing to impaired interleukin 23-dependent interleukin 17 immunity. The clinical features and outcome of candidiasis in these patients have not been described before, to our knowledge. We report here the clinical signs of candidiasis in 35 patients with IL-12Rβ1 deficiency. Most (n = 71) of the 76 episodes of candidiasis were mucocutaneous. Isolated oropharyngeal candidiasis (OPC) was the most common presentation (59 episodes, 34 patients) and was recurrent or persistent in 26 patients. Esophageal candidiasis (n = 7) was associated with proven OPC in 2 episodes, and cutaneous candidiasis (n = 2) with OPC in 1 patient, whereas isolated vulvovaginal candidiasis (VVC; n = 3) was not. Five episodes of proven invasive candidiasis were documented in 4 patients; 1 of these episodes was community acquired in the absence of any other comorbid condition. The first episode of candidiasis occurred earlier in life (median age±standard deviation, 1.5 ± 7.87 years) than infections with environmental mycobacteria (4.29 ± 11.9 years), Mycobacterium tuberculosis (4 ± 3.12 years), or Salmonella species (4.58 ± 4.17 years) or other rare infections (3 ± 11.67 years). Candidiasis was the first documented infection in 19 of the 35 patients, despite the vaccination of 10 of these 19 patients with live bacille Calmette-Guérin. Patients who are deficient in IL-12Rβ1 may have candidiasis, usually mucocutaneous, which is frequently recurrent or persistent. Candidiasis may be the first clinical manifestation in these patients.

    2015-05-01

    The CLN2 form of neuronal ceroid lipofuscinosis is an autosomal recessively inherited lysosomal storage disease that is characterized by progressive vision loss culminating in blindness, cognitive and motor decline, neurodegeneration, and premature death. CLN2 disease results from mutations in the gene that encodes the soluble lysosomal enzyme tripeptidyl peptidase-1. A null mutation in the TPP1 gene encoding this enzyme causes a CLN2-like disease in Dachshunds. Dachshunds that are homozygous for this mutation serve as a model for human CLN2 disease, exhibiting clinical signs and neuropathology similar to those of children with this disorder. Affected dogs reach end-stage terminal disease status at 10-11 months of age. In addition to retinal changes typical of CLN2 disease, a retinopathy consisting of multifocal, bullous retinal detachment lesions was identified in 65% of (TPP1-/-) dogs in an established research colony. These lesions did not occur in littermates that were heterozygous or homozygous for the normal TPP1 allele. Retinal changes and the functional effects of this multifocal retinopathy were examined objectively over time using ophthalmic examinations, fundus photography, electroretinography (ERG), quantitative pupillary light response (PLR) recording, fluorescein angiography, optical coherence tomography (OCT) and histopathology. The retinopathy consisted of progressive multifocal serous retinal detachments. The severity of the disease-related retinal thinning was no more serious in most detached areas than in adjacent areas of the retina that remained in close apposition to the retinal pigment epithelium. The retinopathy observed in these dogs was somewhat similar to canine multifocal retinopathy (CMR), a disease caused by a mutation of the bestrophin gene BEST1. ERG a-wave amplitudes were relatively preserved in the Dachshunds with CLN2 disease, whether or not they developed the multifocal retinopathy. The retinopathy also had minimal effects on the

    Primary candidiasis is rare and often confused with a pre-cancerous lesion, squamous cell carcinoma, or verrucous carcinoma. We report an extremely rare case of squamous cell carcinoma of the vocal cord following primary candidiasis. A 62-year-old man presented to our department reporting a 1-month history of hoarseness. He underwent laryngeal microscopic surgery for a presumptive diagnosis of glottic carcinoma. Histopathologic examination revealed candidiasis and scattered moderate dysplasia. He was treated with itraconazole for 4 weeks, and followed up without any recurrence of candidiasis. However, the 42-month follow-up examination revealed a focal whitish lesion on the right true vocal cord, and a repeat biopsy of this area revealed squamous cell carcinoma without evidence of candidiasis. The patient was treated with radiotherapy and remains well with no signs of tumor recurrence or candidiasis.

    Congenital candidiasis is a severe complication of candidal vulvovaginitis. It occurs in two forms,congenital mucocutaneous candidiasis and congenital systemic candidiasis. Also newborns are in age group the most vulnerable to invasive candidiasis. Congenital candidiasis should be considered as an interdisciplinary problem including maternal and fetal condition (including antibiotic therapy during pregnancy), birth age and rare genetic predispositions as severe combined immunodeficiency or neutrophil-specific granule deficiency. Environmental factors are no less important to investigate in diagnosing, treatment and prevention. External factors (e.g., food) and microenvironment of human organism (microflora of the mouth, intestine and genitalia) are important for solving clinical problems connected to congenital candidiasis. Physician knowledge about microorganisms in a specific compartments of the microenvironment of human organism and in the course of defined disorders of homeostasis makes it easier to predict the course of the disease and allows the development of procedures that can be extremely helpful in individualized diagnostic and therapeutic process.

    The Candida genus expresses virulence factors that, when combined with immunosuppression and other risk factors, can cause different manifestations of oral candidiasis. The treatment of mucosal infections caused by Candida and the elucidation of the disease process have proven challenging. Therefore, the study of experimentally induced oral candidiasis in rats and mice is useful to clarify the etiopathology of this condition, improve diagnosis, and search for new therapeutic options because the disease process in these animals is similar to that of human candidiasis lesions. Here, we describe and discuss new studies involving rat and mouse models of oral candidiasis with respect to methods for inducing experimental infection, methods for evaluating the development of experimental candidiasis, and new treatment strategies for oral candidiasis.

    Women are more susceptible to vaginal candidiasis when the host immune response is suppressed. The antioxidant nutrient beta-carotene is postulated to possess immunoenhancing properties. The purpose of this study was to investigate beta-carotene concentrations in exfoliated vaginal epithelial (EVE) cells in women with vaginal candidiasis. Beta-carotene levels in EVE cells, collected by a saline lavage technique from 22 women with vaginal candidiasis and 20 normal controls, were analyzed. The diagnosis of vaginal candidiasis was established by the presence of pruritus, white cheesy vaginal discharge, and a positive potassium hydroxide preparation. Beta-carotene levels were assayed using high pressure liquid chromatography. Vaginal cell concentrations of beta-carotene were significantly decreased in women with vaginal candidiasis (P < 0.001). Decreased beta-carotene levels, and possibly other antioxidants, may alter the local immune response resulting in disturbances in the vaginal flora, overgrowth of candida, and the development of vaginal candidiasis.

    Assess the impact of esophageal candidiasis on US hospital inpatient charges, length of stay (LOS), and costs across clinically relevant subgroups. Total hospital charge (THC) and LOS data extracted from the 2005 National Inpatient Sample (NIS) were compared for patients with and without esophageal candidiasis within the top 20 most commonly assigned Diagnosis Related Groups (DRGs) for the disease. Total hospital costs were estimated using hospital charges in the 2005 Medicare Provider Analysis and Review (MEDPAR) file and hospital cost-to-charge ratios published in the Center for Medicare and Medicaid Service's (CMS) 2005 Inpatient Prospective Payment System Standardization File. Across 274 DRGs, 45 727 esophageal candidiasis patients were identified. Mean age was 50.8 years; 52.5% were female, 59.3% Caucasian. Median LOS was 7 days; median THC was $25 649. Of all esophageal candidiasis cases identified, 65% fell into the top 20 most commonly assigned DRGs. Within this subset, HIV-related DRGs accounted for 22% of the esophageal candidiasis cases. The difference in mean THC and LOS for esophageal candidiasis patients in HIV-related DRGs was not significant. However, total hospital costs were higher for esophageal candidiasis patients in this subset ($11 886 vs. $10 534, p esophageal candidiasis cases were assigned to 19 non-HIV-related DRGs. Mean LOS, THC, and total hospital costs were significantly higher for esophageal candidiasis patients within these 19 non-HIV-related DRGs, (8.4 vs. 6.1; $35 704 vs. $23 874, and $10 917 vs. $7474, p Esophageal candidiasis affects a wide range of patient groups; it increases LOS and total charges within non-HIV-related hospitalizations. Although the costs presented in this study are estimates, they do suggest a significant increase in cost among esophageal candidiasis cases. Future studies on treatment and preventive care strategies for esophageal candidiasis should not be limited to HIV patients, but instead performed across

    A randomized cross-over clinical and endoscopic evaluation of 85 Ugandan patients showed that esophageal candidiasis in AIDS patients with oral candidiasis could be managed without endoscopy and biopsies. Oral lesions, especially when accompanied by esophageal symptoms, were sufficient for diagnosis. Miconazole was more effective than nystatin in treating esophageal candidiasis and could be a valid alternative to more expensive azolic drugs in developing countries.

    Candidiasis and its causative agent, Candida albicans, have been under continuous study in our clinics and laboratories for the past 20 years. Cultured cells of C albicans and tissues from natural and experimental infections were used for observations by light microscopy, transmission electron microscopy, scanning electron microscopy and freeze fracture techniques. In cultures, the cells of C albicans revealed a more complex cell wall, plasma membrane, intracellular organelles, and biochemical organization than those described in classic text-books on mycology. In infected tissues, noteworthy characteristics of C albicans were prominent vacuoles and invasion of host cells with subsequent intracellular localization and lysis of tissues surrounding the fungus. These findings are discussed in relation to their importance in the pathogenesis and management of candidiasis and to the mechanism of action of anticandida agents.

    Full Text Available Candida-associated denture stomatitis is the most common form of oral candidal infection, with Candida albicans being the principal etiological agent. Candida adheres directly or via an intermediary layer of plaque-forming bacteria to denture acrylic. Despite antifungal therapy to treat denture stomatitis, infection is reestablished soon after the treatment ceases. In addition, many predisposing factors have been identified as important in the development of oral candidiasis, including malnourishment, common endocrine disorders, such as diabetis mellitus, antibacterial drug therapy, corticosteroids, radiotherapy and other immunocompromised conditions, such as acquired immunodeficiency syndrome (AIDS. These often results in increased tolerance to the most commonly used antifungals. So this review suggests new therapies to oral candidiasis.

    Oral cavity is the site of numerous HIV infection manifestations. Oral mucosa candidiasis is the most common one. It may be the earliest sign of the underlying disease. Long lasting observations give evidence that antiretroviral therapy is beneficial also in the cases of this opportunistic infection because it reduces both the number and severity of relapses, however, the prolongation of the patients' survival time creates the need of antifungal therapy prolongation, and thorough observation of its effectiveness and methods. We decided to analyze the influence of antiretroviral therapy with at least three drugs on the development of oral mucosa candidiasis in the out- and inpatients of the Jagiellonian University Medical College Clinic of Infectious Diseases (or Outpatient Clinic) in Cracow. The study was carried out in 75 patients with confirmed HIV infection. We have shown a decrease in the number of fungi present in the oral cavity in patients under antiretroviral treatment as well as higher susceptibility to fluconazole.

    Candida species have been implicated as significant contributors to morbidity in the neonatal period and are associated with 25-50% of mortality in invasive neonatal candidiasis. Peritoneal candidiasis, being paucisymptomatic, cannot often be correctly identified in a preterm neonate. The correct approach to diagnosis of neonatal peritoneal candidiasis is taking into account the epidemiology along with a strong clinical suspicion and appropriate timely diagnostic interventions. We report a case of fatal neonatal peritoneal candidiasis which was misdiagnosed as mucormycosis. © The Author [2016]. Published by Oxford University Press. All rights reserved.

    Full Text Available Kjell Gunnar Gundersen,1 Sarah Makari,2 Steffen Ostenstad,1 Rick Potvin2 1Ifocus Eye Clinic, Haugesund, Norway; 2Science in Vision, Akron, NY, USA Purpose: To determine the incidence and etiology of required retreatment after multifocal intraocular lens (IOL implantation and to evaluate the methods and clinical outcomes of retreatment.Patients and methods: A retrospective chart review of 416 eyes of 209 patients from one site that underwent uncomplicated cataract surgery with multifocal IOL implantation. Biometry, the IOL, and refractive data were recorded after the original implantation, with the same data recorded after retreatment. Comments related to vision were obtained both before and after retreatment for retreated patients.Results: The multifocal retreatment rate was 10.8% (45/416 eyes. The eyes that required retreatment had significantly higher residual refractive astigmatism compared with those who did not require retreatment (1.21±0.51 D vs 0.51±0.39 D, P<0.01. The retreatment rate for the two most commonly implanted primary IOLs, blended bifocal (10.5%, 16/152 and bilateral trifocal (6.9%, 14/202 IOLs, was not statistically significantly different (P=0.12. In those requiring retreatment, refractive-related complaints were most common. Retreatment with refractive corneal surgery, in 11% of the eyes, and piggyback IOLs, in 89% of the eyes, was similarly successful, improving patient complaints 78% of the time.Conclusion: Complaints related to ametropia were the main reasons for retreatment. Residual astigmatism appears to be an important determinant of retreatment rate after multifocal IOL implantation. Retreatment can improve symptoms for a high percentage of patients; a piggyback IOL is a viable retreatment option. Keywords: piggyback IOL, Sulcoflex, toric, STAAR, symptoms, astigmatism

    To compare changes in peripheral refraction with single-vision (SV) and multifocal (MF) correction of distance central refraction with commercially available SV and MF soft contact lenses (SCLs) in young myopic adults. Thirty-four myopic adult subjects were fitted with Proclear Sphere and Proclear Multifocal SCLs to correct their manifest central refractive error. Central and peripheral refraction were measured with no lens wear and subsequently with the two different types of SCL correction. At baseline, refraction was myopic at all locations along the horizontal meridian. Peripheral refraction was relatively hyperopic compared with center at 30 and 35 degrees in the temporal visual field (VF) in low myopes, and at 30 and 35 degrees in the temporal VF, and 10, 30, and 35 degrees in the nasal VF in moderate myopes. Single-vision and MF distance correction with Proclear Sphere and Proclear Multifocal SCLs, respectively, caused a hyperopic shift in refraction at all locations in the horizontal VF. Compared with SV correction, MF SCL correction caused a significant relative myopic shift at all locations in the nasal VF in both low and moderate myopes and also at 35 degrees in the temporal VF in moderate myopes. Correction of central refractive error with SV and MF SCLs caused a hyperopic shift in both central and peripheral refraction at all positions in the horizontal meridian. Single-vision SCL correction caused the peripheral retina, which initially experienced absolute myopic defocus at baseline with no correction to experience an absolute hyperopic defocus. Multifocal SCL correction resulted in a relative myopic shift in peripheral refraction compared with SV SCL correction. This myopic shift may explain recent reports of reduced myopia progression rates with MF SCL correction.

    2014-12-01

    Full Text Available Vaginal candidiasis (VC is one of the most common reasons for consultations with a gynecologist, with an increasing trend in occurrence in female patients. It is estimated that 75% of all women experience an episode of vulvovaginal candidiasis in their lifetime, 50% of them experience at least a second episode, and 5% have recurrent candidiasis. Cervical and vaginal secretions act as the last line of defense from ascendant infection pathway spreading. Factors that may disturb vaginal ecosystem are: endogenous factors, way of life, infectious factors and iatrogenic factors. The most common cause of VC in 85-90% of cases is C. albicans, but other Candida species tend to be more likely to cause VVC (Candida tropicalis , Candida glabrata , C particulary, C crusei and so on. These non-albicans species have been found to be fluconazole and antimycotics resistant in more than 70% of cases. This is especially true for C. glabrata. There are several predisposing factors that have been associated with VC recurrence and resistance, such as Candida genotypes, resistance and virulence, immunodeficiency, unregulated hyperglycemia, use of oral contraceptives, long-term use of antibiotics. Therapy approach should be individual, including local and oral antimycotics until the symptoms disappear. The maintenance dose can be continuous or intermittent. Due to hormone concentration increase, increase in local glycogen, alternations of vaginal flora, VC incidence in pregnancy is two times higher in comparison to other female population. The problem of vaginal candidiasis requires individual approach, taking into account all the risk factors and accompanying physiological conditions or diseases in female patients.

    Full Text Available Introduction. Uncomplicated vulvovaginal candidiasis appears in 75% women of reproductive age. The most frequent causes are Candida albicans (85-95% or C. glabrata, and infrequently C. krusei, C. tropicalis, C. parapsilosis, C. pseudotropicalis, etc. Objective. The aim of the study was to investigate efficiency and safety of fenticonazole for vaginal candidiasis treatment. Methods. Therapeutic effect of a single 600 mg fenticonasole vaginal capsule was observed in 417 women, aged 16-67, in five centers in Serbia. In all women, before the treatment, vaginal candidiasis was confirmed by testing of vaginal smear. Based on smear findings and associated symptoms observed on the 7th and 28th day after therapy administration, treatment results were evaluated. On the next day after drug application the patients recorded by using a questionnaire their own feelings on withdrawal symptoms and possible side effects in the period prior to the first control. Results. Control after seven days showed a statistically significant decrease of symptoms. In 385 women, vaginal smear was found negative to yeast and yeast blastospores. Within the first seven days after treatment 84 women had to repeat therapy due to the persistence of symptoms or positive vaginal smear. After 28 days we recorded full recovery in 392 patients, clinical improvement in eight, no change in 16, and deterioration in one patient only. Side effects were very seldom, mostly in the form of a slight redness of the vulva and vagina, and mild itching during several days. Conclusion. Our observations confirmed good efficacy and safety of fenticonazole in the treatment of vaginal candidiasis.

    Most prostate cancer (PCa) cases are multifocal, and separate foci display histological and molecular heterogeneity. DNA hypermethylation is a frequent alteration in PCa, but interfocal heterogeneity of these changes has not been extensively investigated. Ten pairs of foci from multifocal PCa and 15 benign prostatic hyperplasia (BPH) samples were obtained from prostatectomy specimens, resulting altogether in 35 samples. Methylation-specific PCR (MSP) was used to evaluate methylation status of nine tumor suppressor genes (TSGs), and a set of selected TSGs was quantitatively analyzed for methylation intensity by pyrosequencing. Promoter sequences of the RASSF1 and ESR1 genes were methylated in all paired PCa foci, and frequent (≥75 %) DNA methylation was detected in RARB, GSTP1, and ABCB1 genes. MSP revealed different methylation status of at least one gene in separate foci in 8 out of 10 multifocal tumors. The mean methylation level of ESR1, GSTP1, RASSF1, and RARB differed between the paired foci of all PCa cases. The intensity of DNA methylation in these TSGs was significantly higher in PCa cases than in BPH (p methylation profile of paired PCa foci, while the foci from separate cases with biochemical recurrence showed similar methylation profile and the highest mean levels of DNA methylation. Our findings suggest that PCa tissue is heterogeneous, as between paired foci differences in DNA methylation status were found. Common epigenetic profile of recurrent tumors can be inferred from our data.

    Soft multifocal simultaneous image contact lenses have boomed in recent years due to the growing number of presbyopic patients demanding visual solutions, allowing them to maintain their current standard of living. The concept of 'simultaneous image' is based on blur interpretation and/or blur tolerance of superimposed multiple images on the retina formed by various powers of a contact lens. This is the basis for a specific type of multifocal contact lens developed for the compensation of presbyopia. Manufacturers have released a great variety of soft simultaneous image lens designs to meet different patient needs but their fitting is still unsatisfactory in some cases. Some presbyopes discontinue wearing contact lenses due to some limitations in visual quality and comfort that can be overcome with an appropriate contact lens selection based on a comprehensive pre-fitting evaluation. This paper aims to review the different types of soft multifocal contact lenses that are currently available for presbyopic correction and to define the steps and factors crucial for their fitting, such as pupil, aberrations, accommodation and centring. A discussion about useful tools to achieve a customised fitting leading to a successful outcome, such as the defocus curve, power profile and questionnaires, is performed. © 2016 Optometry Australia.

    To determine the effect of multifocal contact lenses on accommodation and phoria in children. This was a prospective, non-dispensing, randomized, crossover, single-visit study. Myopic children with normal accommodation and binocularity and no history of myopia control treatment were enrolled and fitted with CooperVision Biofinity single vision (SV) and multifocal (MF, +2.50D center distance add) contact lenses. Accommodative responses (photorefraction) and phorias (modified Thorington) were measured at four distances (>3 m, 100 cm, 40 cm, 25 cm). Secondary measures included high- and low-contrast logMAR acuity, accommodative amplitude, and facility. Differences between contact lens designs were analyzed using repeated measures regression and paired t-tests. A total of 16 subjects, aged 10 to 15 years, completed the study. There was a small decrease in high (SV: -0.08, MF: +0.01) and low illumination (SV: -0.03, MF: +0.08) (both P contact lenses exhibited reduced accommodative responses and more exophoria at increasingly higher accommodative demands than with single vision contact lenses. This suggests that children may be relaxing their accommodation and using the positive addition or increased depth of focus from added spherical aberration of the multifocals. Further studies are needed to evaluate other lens designs, different amounts of positive addition and aberrations, and long-term adaptation to lenses.

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

    BACKGROUND Invasive candidiasis is a potential problem for patients receiving long-term immunosuppressive treatment. Psoriatic arthritis is one of many chronic diseases that can be successfully treated with immunosuppressive drugs, in spite of a documented and accepted risk for infectious complications. Critical awareness of possible infection must be part of the surveillance of such patients. CASE REPORT This is the case of a 68-year-old Norwegian male, treated with long-term immunosuppression for psoriatic arthritis, hospitalized with acute subcutaneous and mediastinal emphysema of unknown cause. He died of acute respiratory failure with circulatory collapse shortly after admission. The autopsy revealed mediastinal and subcutaneous emphysema and a mediastinal abscess containing Candida with probable entrance from the esophagus. CONCLUSIONS We consider invasive candidiasis of the esophagus to be the cause of both the chronic abscess and the acute mediastinal emphysema. This case illustrates the importance of awareness of invasive candidiasis as a possible complication in a patient with long-term immunosuppression.

    Many physicians, midwives and lactation consultants still believe that yeasts (particularly Candida spp.) play an important role as an agent of nipple and breast pain despite the absolute absence of scientific proofs to establish such association. In this context, the objective of this study was to investigate the microorganisms involved in sore nipples and/or painful "shooting" breastfeeding by using a variety of microscopy techniques, as well as culture-dependent and-independent identification methods. Initially, 60 women (30 diagnosed as suffering "mammary candidiasis" and 30 with no painful breastfeeding) were recruited to elucidate the role of their pumps on the milk microbial profiles. After realizing the bias introduced by using such devices, manual expression was selected as the collection method for the microbiological analysis of milk samples provided by 529 women with symptoms compatible with "mammary candidiasis". Nipple swabs and nipple biopsy samples were also collected from the participating women. Results showed that the role played by yeasts in breast and nipple pain is, if any, marginal. In contrast, our results strongly support that coagulase-negative staphylococci and streptococci (mainly from the mitis and salivarius groups) are the agents responsible for such cases. As a consequence, and following the recommendations of the US Library of Medicine for the nomenclature of infectious diseases, the term "mammary candidiasis" or "nipple thrush" should be avoided when referring to such condition and replaced by "subacute mastitis".

  5. Nosocomial Candidiasis: Antifungal Stewardship and the Importance of Rapid Diagnosis.

    Pfaller, Michael A; Castanheira, Mariana

    2016-01-01

    Candidemia and other forms of candidiasis are associated with considerable excess mortality and costs. Despite the addition of several new antifungal agents with improved spectrum and potency, the frequency of Candida infection and associated mortality have not decreased in the past two decades. The lack of rapid and sensitive diagnostic tests has led to considerable overuse of antifungal agents resulting in increased costs, selection pressure for resistance, unnecessary drug toxicity, and adverse drug interactions. Both the lack of timely diagnostic tests and emergence of antifungal resistance pose considerable problems for antifungal stewardship. Whereas antifungal stewardship with a focus on nosocomial candidiasis should be able to improve the administration of antifungal therapy in terms of drug selection, proper dose and duration, source control and de-escalation therapy, an important parameter, timeliness of antifungal therapy, remains a victim of slow and insensitive diagnostic tests. Fortunately, new proteomic and molecular diagnostic tools are improving the time to species identification and detection. In this review we will describe the potential impact that rapid diagnostic testing and antifungal stewardship can have on the management of nosocomial candidiasis. © The Author 2015.

    Oral candidiasis is an opportunistic infection caused by yeast of the Candida genus, primarily Candida albicans. It is generally associated with predisposing factors such as the use of immunosuppressive agents, antibiotics, prostheses, and xerostomia. The development of research in animal models is extremely important for understanding the nature of the fungal pathogenicity, host interactions, and treatment of oral mucosal Candida infections. Many oral candidiasis models in rats and mice have been developed with antibiotic administration, induction of xerostomia, treatment with immunosuppressive agents, or the use of germ-free animals, and all these models has both benefits and limitations. Over the past decade, invertebrate model hosts, including Galleria mellonella, Caenorhabditis elegans, and Drosophila melanogaster, have been used for the study of Candida pathogenesis. These invertebrate systems offer a number of advantages over mammalian vertebrate models, predominantly because they allow the study of strain collections without the ethical considerations associated with studies in mammals. Thus, the invertebrate models may be useful to understanding of pathogenicity of Candida isolates from the oral cavity, interactions of oral microorganisms, and study of new antifungal compounds for oral candidiasis.

  7. A review of the ultrastructural features of superficial candidiasis.

    Commensal yeast Candida causes opportunistic infections ranging from superficial lesions to disseminated mycoses in compromised patients. Superficial candidiasis, the commonest form of candidal infections, primarily affects the mucosa and the skin where Candida lives as a commensal. Conversion of candidal commensalism into opportunism at the fungal-epithelial interface is still ill-defined. Nevertheless, fungal virulence mechanisms such as adhesion to epithelia, morphogenesis, production of secretory hydrolytic enzymes, and phenotypic switching are thought to contribute in the process of pathogenesis. On the other hand, host responses in terms of immunity and local epithelial responses are actively involved in resisting the fungal challenge at the advancing front of the infection. Ultrastructural investigations using electron microscopy along with immunohistochemistry, cytochemistry, etc. have helped better viewing of Candida-host interactions. Thus, studies on the ultrastructure of superficial candidiasis have revealed a number of fungal behaviors and associated host responses such as adhesion, morphogenesis (hyphae and appresoria formation), thigmotropism, production and distribution of extracellular enzymes, phagocytosis, and epithelial changes. The purpose of this review is to sum up most of the ultrastructural findings of Candida-host interactions and to delineate the important pathological processes underlying superficial candidiasis.

    Full Text Available Nathan P Wiederhold1, Jason M Cota2, Christopher R Frei11University of Texas at Austin College of Pharmacy, Austin, Texas, USA; 2University of the Incarnate Word Feik School of Pharmacy, San Antonio, Texas, USAAbstract: Micafungin is an echinocandin antifungal agent available for clinical use in Japan, Europe, and the United States. Through inhibition of β-1,3-glucan production, an essential component of the fungal cell wall, micafungin exhibits potent antifungal activity against key pathogenic fungi, including Candida and Aspergillus species, while contributing minimal toxicity to mammalian cells. This activity is maintained against polyene and azole-resistant isolates. Pharmacokinetic and pharmacodynamic studies have demonstrated linear kinetics both in adults and children with concentration-dependent activity observed both in vitro and in vivo. Dosage escalation studies have also demonstrated that doses much higher than those currently recommended may be administered without serious adverse effects. Clinically, micafungin has been shown to be efficacious for the treatment of invasive candidiasis and invasive aspergillosis. Furthermore, the clinical effectiveness of micafungin against these infections occurs without the drug interactions that occur with the azoles and the nephrotoxicity observed with amphotericin B formulations. This review will focus on the pharmacology, clinical microbiology, mechanisms of resistance, safety, and clinical efficacy of micafungin in the treatment of invasive candidiasis and invasive aspergillosis.Keywords: micafungin, echinocandin, Candida, Aspergillus, invasive candidiasis, invasive aspergillosis

    Recurrent vulvovaginal candidiasis (VVC) remains a challenge to manage in clinical practice. Recent epidemiologic studies indicate that non-albicans Candida spp. are more resistant to conventional antifungal treatment with azoles and are considered as causative pathogens of vulvovaginal candidiasis. We searched PubMed and Scopus for studies that reported clinical evidence on the intravaginal use of boric acid for vulvovaginal candidiasis. We identified 14 studies (2 randomized clinical trials [RCTs], 9 case series, and 4 case reports) as eligible for inclusion in this review. Boric acid was compared with nystatin, terconazole, flucytosine, itraconazole, clotrimazole, ketoconazole, fluconazole, buconazole, and miconazole; as monotherapy, boric acid was studied in 7 studies. The mycologic cure rates varied from 40% to 100% in patients treated with boric acid; 4 of the 9 included case series reported statistically significant outcomes regarding cure (both mycologic and clinical) rates. None of the included studies reported statistically significant differences in recurrence rates. Regarding the adverse effects caused by boric acid use, vaginal burning sensation (boric acid is a safe, alternative, economic option for women with recurrent and chronic symptoms of vaginitis when conventional treatment fails because of the involvement of non-albicans Candida spp. or azole-resistant strains.

  14. Multi-focal HIFU reduces cavitation in mild-hyperthermia.

    Chaplin, Vandiver; Caskey, Charles F

    2017-01-01

    Mild-hyperthermia therapy (40-45 °C) with high-intensity focused ultrasound (HIFU) is a technique being considered in a number of different treatments such as thermally activated drug delivery, immune-stimulation, and as a chemotherapy adjuvant. Mechanical damage and loss of cell viability associated with HIFU-induced acoustic cavitation may pose a risk during these treatments or may hinder their success. Here we present a method that achieves mild heating and reduces cavitation by using a multi-focused HIFU beam. We quantify cavitation level and temperature rise in multi-focal sonications and compare it to single-focus sonications at the transducer geometric focus. Continuous wave sonications were performed with the Sonalleve V2 transducer in gel phantoms and pork at 5, 10, 20, 40, 60, 80 acoustic watts for 30 s. Cavitation activity was measured with two ultrasound (US) imaging probes, both by computing the raw channel variance and using passive acoustic mapping (PAM). Temperature rise was measured with MR thermometry at 3 T. Cavitation and heating were compared for single- and multi-focal sonication geometries. Multi-focal sonications used four points equally spaced on a ring of either 4 mm or 8 mm diameter. Single-focus sonications were not steered. Multi-focal sonication generated distinct foci that were visible in MRI thermal maps in both phantoms and pork, and visible in PAM images in phantoms only. Cavitation activity (measured by channel variance) and mean PAM image value were highly correlated (r > 0.9). In phantoms, cavitation exponentially decreased over the 30-second sonication, consistent with depletion of cavitation nuclei. In pork, sporadic spikes signaling cavitation were observed with single focusing only. In both materials, the widest beam reduced average and peak cavitation level by a factor of two or more at each power tested when compared to a single focus. The widest beam reduced peak temperature by at least 10 °C at powers above 5

    Infection is a common cause of morbidity and mortality in kidney transplant recipients. The incidence of esophageal and urogenital candidiasis in kidney and kidney-pancreas transplant recipients has not been well documented. Azoles are safe, effective agents to treat esophageal candidiasis. However, resistance to azoles is now becoming common. This study reports the use of caspofungin for the treatment of azole-resistant esophageal and urogenital candidiasis in kidney transplant recipients. The incidence of esophageal and urogenital candidiasis was evaluated among 140 kidney transplantations and four combined kidney-pancreas transplants performed over a 2-year period. Twenty-two patients (15.7%) presented with esophageal candidiasis, while seven patients (5%) showed urogenital candidiasis. Thirteen patients with esophageal candidiasis (59%) and four patients (57%) with urogenital candidiasis did not improve after a week of azole treatment. A regimen of caspofungin was started in these patients, who tolerated the treatment. Urogenital candidiasis recurred in two patients 2 and 3 months after the treatment. One patient with esophageal candidiasis did not improve with caspofungin and was switched to amphotericin B therapy. There were no other recurrences of candidiasis among patients treated with caspofungin for a median follow-up of 8 months. Renal transplant patients remain at high risk for fungal infections. Although the number of patients was limited, the results of this study indicated that caspofungin is an effective, well-tolerated alternative for difficult-to-treat, azole-resistant candida infections in kidney and pancreas transplant recipients. The high costs of the drug limit the use of caspofungin as first-line antifungal therapy, reserving its use to recipients who had undergone unsuccessful azole therapy.

    Full Text Available Jose A VazquezDivision of Infectious Diseases, Henry Ford Hospital, Wayne State University School of Medicine, Detroit, MI, USAAbstract: Mucocutaneous candidiasis is frequently one of the f irst signs of human immunodeficiency virus (HIV infection. Over 90% of patients with AIDS will develop oropharyngeal candidiasis (OPC at some time during their illness. Although numerous antifungal agents are available, azoles, both topical (clotrimazole and systemic (fluconazole, itraconazole, voriconazole, posaconazole have replaced older topical antifungals (gentian violet and nystatin in the management of oropharyngeal candidiasis in these patients. The systemic azoles, are generally safe and effective agents in HIV-infected patients with oropharyngeal candidiasis. A constant concern in these patients is relapse, which is dependent on the degree of immunosuppression commonly seen after topical therapy, rather than with systemic azole therapy. Candida esophagitis (CE is also an important concern since it occurs in more than 10% of patients with AIDS and can lead to a decrease in oral intake and associated weight loss. Fluconazole has become the most widely used antifungal in the management of mucosal candidiasis. However, itraconazole and posaconazole have similar clinical response rates as fluconazole and are also effective alternative agents. In patients with fluconazole-refractory mucosal candidiasis, treatment options now include itraconazole solution, voriconazole, posaconazole, and the newer echinocandins (caspofungin, micafungin, and anidulafungin.Keywords: oropharyngeal candidiasis, esophageal candidiasis, HAART, antifungal agents, HIV, AIDS

    Background Risk factors for invasive candidiasis in children with candidemia are poorly defined. Methods We performed a retrospective cohort study of all children with candidemia at our tertiary children’s hospital from 2000 to 2006. Invasive candidiasis was diagnosed by review of the medical record and standardized EORTC/MSG criteria. A variety of risk factors for invasive candidiasis were explored. Results Of 194 episodes of candidemia in the microbiology laboratory database, 180 clinical records were available. Evaluation for invasive candidiasis consisted of 174 (97%) echocardiograms; 167 (93%) dilated ophthalmologic examinations, 136 (76%) chest CT scans, and 108 (60%) abdominal ultrasounds (complete, hepatosplenic or renal). Of the 180, 15 (8%) patients were identified with invasive candidiasis (4 proven, 1 probable, 10 possible). Prematurity candidiasis. Conclusions Invasive candidiasis, especially proven or probable, in the setting of candidemia was not common in our hospital, but premature infants and immunocompromised children were at significantly higher risk. Based on our findings, extensive imaging and examination by an ophthalmologist was particularly low-yield for invasive candidiasis in immunocompetent children beyond infancy. PMID:19821906

    Full Text Available The commensal fungus Candida albicans causes mucosal candidiasis in the rapidly expanding number of immunocompromised patients. Mucosal candidiasis includes orapharyngeal, esophageal, gastrointestinal, and vaginal infections. Vulvovaginal candidiasis (VVC and antimycotic-refractory recurrent VVC is a frequent problem in healthy child-bearing women. Both these mucosal infections can affect the quality of life and finding new therapeutical and preventive approaches is a challenge. A vaccine against candidal infections would be a new important tool to prevent and/or cure mucosal candidiasis and would be of benefit to many patients. Several Candida antigens have been proposed as vaccine candidates including cell wall components and virulence factors. Here we discuss the recent progress and problems associated with vaccination against mucosal candidiasis.

    Various causes of intractable hiccups have been reported; however, to the best of our knowledge, there are no previous reports of either intractable hiccups due to esophageal candidiasis in an immunocompetent adult or improvement following antifungal therapy. An 87-year-old man presented with intractable hiccups. Although the patient was immunocompetent, he used proton pump inhibitors. An esophagogastroduodenos-copy revealed several white deposits throughout the esophagus and extensive white deposits in the midesophageal diverticulum. A mucosal culture showed candidiasis, which was suspected to be the cause of the intractable hiccups. After oral fluconazole had been prescribed, the candidiasis resolved and the hiccups improved. Therefore, we concluded that esophageal diverticular candidiasis was the cause of his intractable hiccups. Physicians should consider esophageal candidiasis as one of the differential diagnoses for intractable hiccups, even in immunocompetent adults.

    2007-01-01

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

    Chronic granulomatous disease (CGD) is a primary immunodeficiency that leads to severe recurrent infection and inflammatory complications that are usually difficult to diagnose and treat. Several hyperinflammation mechanisms, such as decreased neutrophil apoptosis, toll-like receptor activation imbalance, Th17 cell induction, Nrf2 activity deficiency, and inflammasome activation, have been described in CGD patients However, there have been no reports of chronic recurrent multifocal osteomyelitis as an inflammatory complication in CGD, and the differential diagnosis of this condition with infectious osteomyelitis is challenging. Thalidomide has been used to treat several inflammatory manifestations in CGD patients with good clinical results. Here, we report the case of a previously asymptomatic 11-year-old boy who consulted for difficulty walking and pain at the back of the right thigh, with increased inflammatory markers. Multifocal bone involvement was seen on bone scintigraphy, and acute-phase reactants were elevated. On the basis of a suspected diagnosis of infectious osteomyelitis, broad-spectrum antibiotic therapy was started, with no clinical response. Bone biopsy and microbiological tests yielded negative results; at that point, chronic recurrent multifocal osteomyelitis was suspected. The patient was unresponsive to nonsteroidal antiinflammatory drugs and corticosteroids. Thalidomide was started, and within 6 months, clinical and radiologic resolution of the condition was achieved with no adverse effects. More than 1 year after stopping thalidomide, the patient remained free of symptoms and inflammatory parameters are within normal levels. Thalidomide has a favorable safety profile compared with other alternatives and could be considered a feasible therapeutic option for this type of condition in selected patients.

    We report a radiologic finding on magnetic resonance imaging (MRI) of the brain of two cases of progressive multifocal leukoencephalopathy (PML) of hypointense signal of subcortical U-fibres on susceptibility weighted (SW) sequence. The first case is a 50-year-old man recently treated with chemotherapy including rituximab for non-Hodgkin\\'s lymphoma. The second case is a 64-year-old woman with human immunodeficiency virus (HIV) infection. Iron deposition is a likely causative factor. We propose that SWI may be especially useful in the assessment of indeterminate cases to reduce the likelihood of a missed diagnosis of PML

    Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease resulting from infection of oligodendrocytes in the central nervous system with John Cunningham virus. Although PML is commonly diagnosed in immunocompromised patients with human immunodeficiency virus, it can also arise in other immunodeficient states. In this report, we present an unusual case of PML occurring 40years after chemoradiation therapy for Hodgkin lymphoma in a patient with normal total lymphocyte counts on annual surveillance. Although current guidelines recommend annual complete blood counts for patients in remission, this testing may be insufficient to monitor patients with chronic CD4+ lymphopenia.

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

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

    Two multifocal corneal models and an aspheric model designed to correct presbyopia by corneal photoablation were evaluated. The design of each model was optimized to achieve the best visual quality possible for both near and distance vision. In addition, we evaluated the effect of myosis and pupil decentration on visual quality. The corrected model with the central zone for near vision provides better results since it requires less ablated corneal surface area, permits higher addition values, presents stabler visual quality with pupil-size variations and lower high-order aberrations.

    Full Text Available El envejecimiento es un proceso dinámico de modificaciones morfológicas, funcionales, psicológicas y bioquímicas que se inician en el momento del nacimiento y se desarrollan a lo largo de nuestras vidas. Envejecer no es lo mismo que enfermarse; en el camino hacia el envejecimiento se van produciendo cambios en los órganos y sistemas. En el envejecimiento aumenta el riesgo de adquirir enfermedades e incapacidades, y con ello, la necesidad de trazar metas para mejorar la salud del adulto mayor. Basándonos en esas inquietudes, nos proponemos describir los cambios bucales en los adultos mayores, así como determinar la relación entre sexo y alteraciones sistémicas con la aparición de cambios bucales en el adulto mayor. Se encontró un mayor porcentaje de cambios bucales en los adultos mayores desdentados totales. El reborde alveolar reabsorbido fue el cambio bucal más frecuente. En el sexo femenino se reportó el mayor número de cambios bucales y se evidenció una relación directa entre las alteraciones sistémicas y los cambios bucales, dentro de los cuales el grupo de pacientes diabéticos fue el más afectado.Aging is a dynamic process of morphological, functional, psychological and biochemical modifications that start at birth and develop throughout our lives. Getting old is not the same as getting sick. Along the aging road, a series of changes in the organs and systems take place. In the aging process, the risk of acquiring diseases and disabilities increases, as well as the need to lay down goals to improve the older adult's health. Based on these concerns, we proposed to describe the oral changes occurring in older adults, and to determine the relationship between sex and systemic alterations with the appearance of oral changes in the older adult. A higher percentage of oral changes was found in the totally edentulous older adults. The reabsorbed alveolar crest was the most frequent oral change. The greatest number of oral

  7. Multifocal Motor Neuropathy, Multifocal Acquired Demyelinating Sensory and Motor Neuropathy and Other Chronic Acquired Demyelinating Polyneuropathy Variants

    2014-01-01

    Chronic acquired demyelinating neuropathies (CADP) are an important group of immune neuromuscular disorders affecting myelin. These are distinct from chronic inflammatory demyelinating polyneuropathy (CIDP). Classically, CIDP is characterized by proximal and distal weakness, large fiber sensory loss, elevated cerebrospinal fluid (CSF) protein content, demyelinating changes nerve conduction studies or nerve biopsy, and response to immunomodulating treatment. In this chapter we discuss CADP with emphasis on multifocal motor neuropathy (MMN), multifocal acquired demyelinating sensory and motor neuropathy (MADSAM), distal acquired demyelinating symmetric (DADS) neuropathy and conclude with less common variants. While each of these entities has distinctive laboratory and electrodiagnostic features that aid in their diagnosis, clinical characteristics are of paramount importance in diagnosing specific conditions and determining the most appropriate therapies. Unlike CIDP, MMN is typically asymmetric and affects only the motor nerve fibers. MMN is a rare disease that presents chronically, over several years of progression affecting the arms are more commonly than the legs. Men are more likely than women to develop MMN. MADSAM should be suspected in patients who have weakness and loss of sensation in primarily one arm or leg which progresses slowly over several months to years. It is important in patient with multifocal demyelinating clinical presentation to distinguish MMN from MADSAM since corticosteroids are not effective in MMN where the mainstay of therapy is intravenous gammaglobulin (IVIg). DADS can be subdivided into DADS-M (associated woth M-protein) and DADS-I which is idioapthic. While DADS-I patients respond somewhat to immunotherapy, DADS-M patients present with distal predominant sensorimotor demyelinating neuropathy phenotype and are notoriously refractory to immunotherapies regardless of antibodies to myelin-associated glycoprotein (MAG).

    2011-05-01

    Full Text Available Abstract Background Glaucoma is the second-leading cause of blindness worldwide and early diagnosis is essential to its treatment. Current clinical methods based on multifocal electroretinography (mfERG essentially involve measurement of amplitudes and latencies and assume standard signal morphology. This paper presents a new method based on wavelet packet analysis of global-flash multifocal electroretinogram signals. Methods This study comprised twenty-five patients diagnosed with OAG and twenty-five control subjects. Their mfERG recordings data were used to develop the algorithm method based on wavelet packet analysis. By reconstructing the third wavelet packet contained in the fourth decomposition level (ADAA4 of the mfERG recording, it is possible to obtain a signal from which to extract a marker in the 60-80 ms time interval. Results The marker found comprises oscillatory potentials with a negative-slope basal line in the case of glaucomatous recordings and a positive-slope basal line in the case of normal signals. Application of the optimal threshold calculated in the validation cases showed that the technique proposed achieved a sensitivity of 0.81 and validation specificity of 0.73. Conclusions This new method based on mfERG analysis may be reliable enough to detect functional deficits that are not apparent using current automated perimetry tests. As new stimulation and analysis protocols develop, mfERG has the potential to become a useful tool in early detection of glaucoma-related functional deficits.

    The purpose of this study was to investigate the influence of pupil diameter on the amplitude and latency of multifocal visual evoked potentials (mfVEP). The multifocal objective perimeter (Accumap; Objectivision) was used to stimulate the visual field at 56 sites extending to 32 degrees using a pseudo-random pattern stimulus. The mfVEP were recorded using bipolar occipital electrodes, 7 min/eye. Ten normal subjects were recruited from the community and one eye was randomly selected for testing. The mfVEP were recorded at four different pupil diameters (2 mm, 4 mm, 6 mm, 8 mm), obtained by applying tropicamide (0.5%) or pilocarpine (2%) in different dilutions. Appropriate refractive correction was provided to overcome cycloplegia and achieve a visual acuity of 6/7.5 or better. Analysis revealed that at most pupil diameters the normalized full field amplitude did not show significant variation, except at the most miotic pupil diameter (2 mm), where the amplitude became reduced, based on 2-way anova and Tukey's T method. There was, however, significant correlation between latency and pupil area (correlation coefficient: upper field -0.63, lower field -0.76). The results suggest that even in the presence of mydriatics or miotics, the mfVEP test can be used to assess diseases that affect amplitude, provided near correction is used. The interpretation of latency, however, must be made with caution, as a borderline conduction defect with a dilated pupil may appear normal.

    2011-01-01

    Full Text Available A ganglioneuroma (GN is the rarest and most benign of the neuroblastic tumors and originates from neural crest cells wherever sympathetic nervous tissue exists, such as in the retroperitoneum and adrenal gland. The diagnosis can be very challenging, given the rarity and asymptomatic presentation of this neoplasia, and can be achieved only by means of histological evaluation. Although benign, a few cases of metastatic GNs have been reported in the literature. The prognosis, however, seems to be excellent after surgical resection. We describe a rare case of multifocal retroperitoneal GN, diagnosed incidentally in a 46-year-old woman, with para-aortic and adrenal localizations. After intraoperative pathological diagnosis was made, complete excision of all the visible masses was performed. The postoperative period was uneventful and she was recurrence free 3 months after surgery. To our knowledge, this is the first case report of a multifocal retroperitoneal GN. Among the broad differential diagnoses of adrenal incidentalomas, an adrenal location of neuroblastic tumors should not be forgotten.

Although there is not enough studies about duedonal white spots yet; these lesions described in a separate syndrome. Here now we reported a case that we diagnosed multiple Duodenal white spots mimicking intestinal candidiasis. Clinical manifestation and endoscopic appearance of lesions gave rise to thought intestinal candidiasis histopathological examination revealed us several duodenitis. There was no evidence of fungal infection in PAS staining. Early after endoscopy patient took treatment of Lansoprozole at the 30 mg dose and bismuth salicylate. Patients compliant declined and control endoscopy exposed white duodenal spots cleared away three months later. Duodenal white spots are becoming to be designated as a separate disease even a syndrome. Etiology of duodenal white spots must be determined carefully during endoscopy. Sometimes it is difficult to make the correct diagnosis by appearance of lesion; in such cases histopathological examination can be useful both differential diagnosis of disease and determination of etiological factor.

    Chronic mucocutaneous candidiasis (CMC) is a rare disorder characterized by persistent or recurrent candidal infections of the skin, nails and mucous membranes or by a variable combination of endocrine failure as well as immunodeficiency. Oral clinicopathological features of CMC have seldom been described in detail. Seven patients with CMC were reported in the study. The clinical and histological findings, etiological Candida species, immunological evaluation, and therapeutic pattern of oral lesions, were analyzed. Long-standing whitish hyperplastic and nodule-like lesions with exaggerated deep fissure were the typical and characteristic oral manifestations presented by all patients. The tongue was the most common site affected. Histologically, no obvious distinction was found between CMC and other forms of candidal infection. Abnormal proportions of T-lymphocyte subsets and positive titers of autoantibody were observed in three subjects (42.9%) and one patient (14.3%) respectively. Meanwhile, four subjects (57.1%) showed decreased albumin and increased globulin, three cases (42.9%) had high levels of ESR. But no iron deficiency was found. Candida albicans was the microorganism isolated from these patients. Multiple and widespread candidal infectious lesions can be observed on the oral cavity of CMC patients. Hyperplastic and nodule-like lesion with irremovable whitish patches and deep fissure are the most common oral manifestations of these patients. Dentists, otolaryngologists and pediatricians should be familiar with the clinical appearances of CMC to make an accurate diagnosis. Potential systemic disorders should be concerned to avoid the reoccurrence of oral candidiasis.

    To investigate factors that predispose breastfeeding mothers to nipple candidiasis. A retrospective case-control study of women attending the Calgary Breastfeeding Clinic. Ambulatory breastfeeding referral centre. All women (105) who attended the clinic during a 3.5-month study period. All were referred for problems with breastfeeding; 27 (the case group) had positive diagnostic criteria for nipple candidiasis. The other 78 formed a control group. A patient information sheet, completed while taking a medical history, recorded the presence or absence of four possible predisposing factors. Two infant variables were also noted on physical examination. Patients were diagnosed as having or not having nipple candidiasis on the basis of specific clinical criteria, and statistics on other variables were compared for those with positive and with negative diagnoses. A statistically significant correlation (P < 0.05) was found between nipple candidiasis and three factors: vaginal candidiasis (P = 0.001), previous antibiotic use (P = 0.036), and nipple trauma (P = 0.001). Further research is required to establish clear causality. However, we recommend that physicians be suspicious of nipple candidiasis; avoid antibiotics or use the shortest effective course; treat yeast vaginitis during the third trimester and after delivery aggressively; and treat mothers for nipple yeast if babies have oral or diaper candidiasis. Breastfeeding mothers can also be counseled in preventive measures.

    The aim of this study was to evaluate the risk of esophageal candidiasis in asthma patients who are on inhaled steroids without any other risk factors for esophageal candidiasis by comparing the treatment group with the control group. Moreover, the oropharyngeal and esophageal Candida colonizations were evaluated in the subgroups of both control and treatment groups. Upper gastrointestinal system endoscopic evaluation was performed in 40 asthma patients who were on inhaled steroids for at least 1 month. The control group consisted of 40 steroid naïve patients without asthma. Oral and esophageal samples were obtained for performing quantitative culture. Candida growth in cultures without any clinical signs and symptoms was described as colonization. Candida growth accompanied by clinical signs and symptoms was described as infection. None of the patients in the control group had either esophageal or oropharyngeal candidiasis; however, one (2.5%) asthma patient had esophageal candidiasis and two (5%) asthma patients had oropharyngeal candidiasis. Esophageal and oropharyngeal Candida colonization was determined in 5 (22.7%) and 11 (50%) of the asthma patients and 7 (31%) and 9 (41%) of the control group, respectively. Although the mean numbers of Candida colonies were higher in the asthma group in both localizations, there were no statistically significant differences between the two groups regarding esophageal or oropharyngeal Candida colonization. The risk of esophageal candidiasis due to inhaled steroids is low and inhaled steroids may be used safely in terms of esophageal candidiasis. Future prospective studies are needed to draw more definitive conclusions.

    Background. Vulvovaginal candidiasis is characterized by curd-like vaginal discharge and itching, and is associated with considerable health and economic costs. Materials and Methods. We examined the incidence, prevalence, and risk factors for vulvovaginal candidiasis among a cohort of 898 women in south India. Participants completed three study visits over six months, comprised of a structured interview and a pelvic examination. Results. The positive predictive values for diagnosis of vulvovaginal candidiasis using individual signs or symptoms were low (candidiasis. Women clinically diagnosed with bacterial vaginosis had a higher prevalence of vulvovaginal candidiasis (Prevalence 12%, 95% CI 8.2, 15.8) compared to women assessed to be negative for bacterial vaginosis (Prevalence 6.5%, 95% 5.3, 7.6); however, differences in the prevalence of vulvovaginal candidiasis were not observed by the presence or absence of laboratory-confirmed bacterial vaginosis. Conclusions. For correct diagnosis of vulvovaginal candidiasis, laboratory confirmation of infection with Candida is necessary as well as assessment of whether the discharge has been caused by bacterial vaginosis. Studies are needed of women infected with Candida yeast species to determine the risk factors for yeast's overgrowth. PMID:23118494

    To investigate the relationship between vaginal and intestinal candida in patients with vulvovaginal candidiasis by using microbiological and molecular methods. The samples of vaginal discharge and anal swabs were collected from 148 cases with vulvovaginal candidiasis, followed by fungal culture, identification, purification and genome DNA extraction. The genome sequences from respective locations were aligned and typed according to their homology analyzed by internal transcribed spacer (ITS) PCR and random amplified polymorphic DNA (RAPD) PCR. Patients with vulvovaginal infection or those with infections in intestine and vulvovagina were pooled respectively, while the recurrent incidences after local anti-fungal treatments were analyzed. Candida albicans is the dominant pathogen in 148 cases with vulvovaginal candidiasis (91.9%, 136/148); 33.1% (49/148) of patients with vulvovaginal candidiasis were infected in both intestine and vulvovagina. While 92% (22/24) of patients with intestinal and vaginal candida infection showed high homology. The recurrent rate of patients with vulvovaginal candidiasis complicated with concurrent intestinal candida infection (7/14) was significantly higher than that of solo vaginal infected patients [21% (6/29)] after vaginal treatment (Pinfection of vulvovaginal candidiasis is highly associated with the concurrent infection of intestinal candida. The recurrent rate is high in patients with vulvovaginal candidiasis with concurrent infection of intestinal candida after vaginal treatment. The general management to those patients infected by both vulvovaginal and intestinal candida is necessary in reducing the recurrence of the disease.

    Full Text Available Background. Vulvovaginal candidiasis is characterized by curd-like vaginal discharge and itching, and is associated with considerable health and economic costs. Materials and Methods. We examined the incidence, prevalence, and risk factors for vulvovaginal candidiasis among a cohort of 898 women in south India. Participants completed three study visits over six months, comprised of a structured interview and a pelvic examination. Results. The positive predictive values for diagnosis of vulvovaginal candidiasis using individual signs or symptoms were low (<19%. We did not find strong evidence for associations between sociodemographic characteristics and the prevalence of vulvovaginal candidiasis. Women clinically diagnosed with bacterial vaginosis had a higher prevalence of vulvovaginal candidiasis (Prevalence 12%, 95% CI 8.2, 15.8 compared to women assessed to be negative for bacterial vaginosis (Prevalence 6.5%, 95% 5.3, 7.6; however, differences in the prevalence of vulvovaginal candidiasis were not observed by the presence or absence of laboratory-confirmed bacterial vaginosis. Conclusions. For correct diagnosis of vulvovaginal candidiasis, laboratory confirmation of infection with Candida is necessary as well as assessment of whether the discharge has been caused by bacterial vaginosis. Studies are needed of women infected with Candida yeast species to determine the risk factors for yeast’s overgrowth.

    Results and Conclusion: There was gradual but significant reduction in Candidal CFU count in both groups. At the end of the treatment, Candidal CFU count reduction in ozone group (60.5% reduction was more than the clotrimazole group (32.3% reduction. 14 patients (70% with candidiasis in ozone group were reduced to 6 (30% whereas only 8 patients (40% out of 13 (65% in clotrimazole group, although intergroup comparison was not statistically significant. Ozone therapy was much more effective in reducing the patients with candidiasis to a state of carriers. These findings suggest that ozonated water might be useful to treat oral candidiasis.

    A 75-year-old woman who had been healthy except for mild glycemia and lipidemia discovered three and a half months before admission experienced severe dysphagia secondary to oral and esophageal candidiasis. She eventually developed diabetic hyperosmolar syndrome and ketoacidosis. Since anti-GAD antibody was negative and her diabetes was controlled with a moderate dose of insulin, we made a diagnosis of type 2 diabetes. Her only risk factors for candidiasis were hyperglycemia, age, and continuous denture use. The fact that her diabetes developed in association with oral candidiasis supports the hypothesis that there is a bidirectional interrelationship between diabetes and oral infection.

    To assess the clinical visual outcomes of bilateral implantation of Restor +2.5 diopter (D) multifocal intraocular lenses (IOLs) and contralateral implantation of a Restor +2.5 D multifocal IOL in the dominant eye and Restor +3.0 D multifocal IOL in the fellow eye. Multicenter study at 8 investigative sites. Prospective randomized parallel-group patient-masked 2-arm study. This study comprised adults requiring bilateral cataract extraction followed by multifocal IOL implantation. The primary endpoint was corrected intermediate visual acuity (CIVA) at 60 cm, and the secondary endpoint was corrected near visual acuity (CNVA) at 40 cm. Both endpoints were measured 3 months after implantation with a noninferiority margin of Δ = 0.1 logMAR. In total, 103 patients completed the study (53 bilateral, 50 contralateral). At 3 months, the mean CIVA at 60 cm was 0.13 logMAR and 0.10 logMAR in the bilateral group and contralateral group, respectively (difference 0.04 logMAR), achieving noninferiority. Noninferiority was not attained for CNVA at 40 cm; mean values at 3 months for bilateral and contralateral implantation were 0.26 logMAR and 0.11 logMAR, respectively (difference 0.15 logMAR). Binocular defocus curves suggested similar performance in distance vision between the 2 groups. Treatment-emergent ocular adverse events rates were similar between the groups. Bilateral implantation of the +2.5 D multifocal IOL resulted in similar distance as contralateral implantation of the +2.5 D multifocal IOL and +3.0 D multifocal IOL for intermediate vision (60 cm), while noninferiority was not achieved for near distances (40 cm).

    Epidemiologic studies have indicated that elderly people who wear multifocal spectacles have an increased risk of tripping, particularly on stairs. Yet no studies have experimentally examined how wearing multifocal spectacles affects stair and step negotiation. The purpose of this study was to determine the effects of wearing multifocal compared with single-distance vision spectacles on minimum toe clearance and risk of tripping during step negotiation in the elderly. Nineteen healthy subjects (mean age, 71.4 years) performed a single step up to a new level (heights, 7.5, 15, and 22 cm) while wearing multifocal (bifocals and progressive addition lenses) or single-distance vision spectacles. Minimum horizontal and vertical toe clearance were assessed by analyzing data collected with a five-camera, three-dimensional motion-analysis system. There was no difference in mean minimum toe clearance in subjects when wearing multifocal compared with single-distance vision spectacles. However, there was greater within-subject variability in vertical toe clearance when wearing multifocal spectacles (variance ratio, 1.53; P = 0.0004). Subjects were also significantly more likely to trip when wearing multifocal compared with single-vision spectacles (one-sided Fisher's exact test P = 0.025). Because of increased within-subject variability in vertical toe clearance when wearing multifocal spectacles, elderly individuals may be at greater risk of falling when negotiating steps and stairs if they do not also consistently increase margins of safety (mean vertical toe clearance). This suggests that some elderly who are at high risk of falling may benefit from wearing single-distance vision rather than multifocal spectacles when walking.

    Our research on pathogenesis of disseminated candidiasis led to the discovery that antibodies specific for Candida albicans cell surface β-1, 2–mannotriose [β-(Man)3] protect mice. A 14 mer peptide Fba, which derived from the N-terminal portion of the C. albicans cytosolic/cell surface protein fructose-bisphosphate aldolase, was used as the glycan carrier and resulted in a novel synthetic glycopeptide vaccine β-(Man)3-Fba. By a dendritic cell-based immunization approach, this conjugate induced protective antibody responses against both the glycan and peptide parts of the vaccine. In this report, we modified the β-(Man)3-Fba conjugate by coupling it to tetanus toxoid (TT) in order to improve immunogenicity and allow for use of an adjuvant suitable for human use. By new immunization procedures entirely compatible with human use, the modified β-(Man)3-Fba-TT was administered either alone or as a mixture made with alum or monophosphoryl lipid A (MPL) adjuvants and given to mice by a subcutaneous (s.c.) route. Mice vaccinated with or, surprisingly, without adjuvant responded well by making robust antibody responses. The immunized groups showed a high degree of protection against a lethal challenge with C. albicans as evidenced by increased survival times and reduced kidney fungal burden as compared to control groups that received only adjuvant or DPBS buffer prior to challenge. To confirm that induced antibodies were protective, sera from mice immunized against the β-(Man)3-Fba-TT conjugate transferred protection against disseminated candidiasis to naïve mice, whereas C. albicans-absorbed immune sera did not. Similar antibody responses and protection induced by the β-(Man)3-Fba-TT vaccine was observed in inbred BALB/c and outbred Swiss Webster mice. We conclude that addition of TT to the glycopeptide conjugate results in a self-adjuvanting vaccine that promotes robust antibody responses without the need for additional adjuvant, which is novel and represents a

    Progressive multifocal leukoencephalopathy (PML) is a subacute demyelinating slow-virus encephalitis caused by the JC polyomavirus in 2-5% of patients with AIDS. MRI typically shows multiple lesions in the cerebral hemispheres. We present a rare case of rapidly evolving and lethal PML with a severe bulbar syndrome and spastic tetraparesis in a patient with AIDS. MRI showed high-signal lesions on T2-weighted images confined to the brain stem, extending from the medulla oblongata to the midbrain. JC virus polymerase chain reaction in cerebrospinal fluid was positive, and neuropathology showed the findings of PML. This case was also notable because of the rapid progression despite improved immune status with antiretroviral therapy. (orig.)

    Full Text Available Multifocal multiphoton microscopy (MMM has greatly improved the utilization of excitation light and imaging speed due to parallel multiphoton excitation of the samples and simultaneous detection of the signals, which allows it to perform three-dimensional fast fluorescence imaging. Stochastic scanning can provide continuous, uniform and high-speed excitation of the sample, which makes it a suitable scanning scheme for MMM. In this paper, the graphical programming language — LabVIEW is used to achieve stochastic scanning of the two-dimensional galvo scanners by using white noise signals to control the x and y mirrors independently. Moreover, the stochastic scanning process is simulated by using Monte Carlo method. Our results show that MMM can avoid oversampling or subsampling in the scanning area and meet the requirements of uniform sampling by stochastically scanning the individual units of the N × N foci array. Therefore, continuous and uniform scanning in the whole field of view is implemented.

    Polyostotic bone and bone marrow lesions in children may be due to various disorders. Radiographically, lytic lesions may become apparent after loss of more than 50% of the bone mineral content. Scintigraphy requires osteoblastic activity and is not specific. MRI may significantly contribute to the correct diagnosis and management. Accurate interpretation of MRI examinations requires understanding of the normal conversion pattern of bone marrow in childhood and of the appearances of red marrow rests and hyperplasia. Differential diagnosis is wide: Malignancies include metastases, multifocal primary sarcomas and hematological diseases. Benign entities include benign tumors and tumor-like lesions, histiocytosis, infectious and inflammatory diseases, multiple stress fractures/reactions and bone infarcts/ischemia. (orig.)

    To investigate if initial multifocal contact lens (MFCL) performance predicts short-term dispensing performance. A retrospective analysis of 55 participants (Px) in a masked, crossover, clinical trial, using ACUVUE OASYS for Presbyopia and AIR OPTIX AQUA Multifocal. Subjective questionnaires were administered at the following instances: initial fitting, two take home questionnaires (THQ) completed between days 2 and 4 and at assessment, ≥5 days after fitting. Questionnaires included vision clarity and lack of ghosting at distance, intermediate and near at day/night time points rated on a 1 to 10 (1-step, 10 most favorable) rating scale. Vision stability, vision while driving, overall vision satisfaction, willingness to purchase and comfort, as well as acuity-based measures were also collected. There were no statistical differences in comfort and vision at all distances, in vision stability or driving at either time points between THQ and assessment (P>0.05). However, there was a statistical decline in subjective overall vision satisfaction and comfort between fitting and assessment visits (P<0.001). Willingness to purchase remained the same at fitting and assessment in 68% of Px, whereas only 4% of Px converted to a positive willingness to purchase at assessment. The majority of acuity-based measures remained constant between fitting and assessment visits. Initial performance at fitting was not able to predict short-term performance of MFCL. Subjective measures peaked at fitting and declined thereafter whereas acuity-based measures remained constant. Utility of subjective rating tools may aid practitioners to gauge success of MFCL.

    Many contact lens (CL) manufacturers produce simultaneous-image lenses in which power varies either smoothly or discontinuously with zonal radius. We present in vitro measurements of some recent CLs and discuss how power profiles might be approximated in terms of nominal distance corrections, near additions, and on-eye visual performance. Fully hydrated soft, simultaneous-image CLs from four manufacturers (Air Optix AQUA, Alcon; PureVision multifocal, Bausch & Lomb; Acuvue OASYS for Presbyopia, Vistakon; Biofinity multifocal- "D" design, Cooper Vision) were measured with a Phase focus Lens Profiler (Phase Focus Ltd., Sheffield, UK) in a wet cell and powers were corrected to powers in air. All lenses had zero labeled power for distance. Sagittal power profiles revealed that the "low" add PureVision and Air Optix lenses exhibit smooth (parabolic) profiles, corresponding to negative spherical aberration. The "mid" and "high" add PureVision and Air Optix lenses have bi-aspheric designs, leading to different rates of power change for the central and peripheral portions. All OASYS lenses display a series of concentric zones, separated by abrupt discontinuities; individual profiles can be constrained between two parabolically decreasing curves, each giving a valid description of the power changes over alternate annular zones. Biofinity lenses have constant power over the central circular region of radius 1.5 mm, followed by an annular zone where the power increases approximately linearly, the gradient increasing with the add power, and finally an outer zone showing a slow, linear increase in power with a gradient being almost independent of the add power. The variation in power across the simultaneous-image lenses produces enhanced depth of focus. The through-focus nature of the image, which influences the "best focus" (distance correction) and the reading addition, will vary with several factors, including lens centration, the wearer's pupil diameter, and ocular

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

    Full Text Available OBJETIVO: O objetivo do presente estudo foi o de verificar a prevalência das lesões superficiais da mucosa da cavidade bucal em pacientes diabéticos. MÉTODOS: A amostra foi constituída de 30 pacientes. Para a obtenção dos resultados foram realizados exames clínicos criteriosos e exames complementares quando necessário. RESULTADOS: Dos 30 indivíduos, 9 (30% eram do sexo masculino e 21 (70%, do sexo feminino. Dos pacientes estudados, 40% tinham idade até 60 anos e 60% possuíam idade superior. Foram diagnosticados 13 diferentes tipos de alterações da mucosa em diversas regiões, sendo a varicosidade lingual (36,6% e a candidíase (27,02% as mais prevalentes. Tais alterações podem estar relacionadas ao fato de serem achados semiológicos comuns em pacientes senis e também ao uso prolongado de próteses. A xerostomia foi diagnosticada em apenas 1 (3,33% paciente divergindo da maioria dos estudos observados na literatura. CONCLUSÃO: A maioria dos pacientes diabéticos apresentou pelo menos um tipo de lesão da mucosa bucal.AIM: The present study aimed to evaluate the prevalence of superficial lesions in the oral cavity mucosa in diabetic patients. METHODS: The sample was made of 30 patients. To obtain these results we did rigorous clinical and complementary tests. RESULTS: Of the 30 patients, 9 (30% were males and 21 (70% females. Of the studied patients, 40% were below 60 years of age, and 60% were older than 60 years. Thirteen different types of mucosal alterations were diagnosed. Tongue varicose veins (36.6% and candidiasis (27.02% were the most prevalent. Such alterations can be associated with the fact that these conditions are commonly found in senile patients and are also associated with prolonged wear of dentures. Xerostomia was diagnosed in only 1 (3.33% patient, disagreeing with most of the studies observed in the literature. CONCLUSION: Most of the diabetic patients presented at least one type of oral mucosa lesion or

    Background. According to the limited studies reporting new treatments for vulvovaginal candidiasis, this study was designed to compare the combination of fluconazole and oral protexin with fluconazole in the treatment of vulvovaginal candidiasis. Methods. A double-blind clinical trial was conducted, involving 90 women who were referred to the gynecology clinic. Vulvovaginal candidiasis was diagnosed with itching, cheesy vaginal discharge, and any one of the following: dysuria, pH protexin and fluconazole-placebo, were equally effective in reduction of complaints and symptoms, but fluconazole-oral protexin combination elicited a better therapeutic response (χ(2) = 0.01, P = 6.7). In addition, fluconazole-oral protexin combination treatment demonstrated better recovery time (t = -2.04, P = 0.04). Conclusion. This study demonstrated that complementary treatment with probiotic Lactobacillus increased the efficacy of fluconazole in treatment of vulvovaginal candidiasis. Further research is recommended.

    Cerebral candidiasis is a devastating disease which contributes to a high mortality. Most of the cerebral candidiasis are never microbiologically or radiologically confirmed. In this case, a 4-year-old boy who developed cerebral candidiasis was successfully rescued and presented. The diagnosis of cerebral candidiasis was established based on both microbiologic and radiologic examinations. The pathogen was revealed to be Candida albicans by cerebrospinal fluid and central venous catheter cultures, and the cerebral involvement was recorded by series head magnetic resonance imaging (MRI) with an appearance of special encephalitis demonstrated. The imaging studies played a critical role throughout the diagnosis and treatment. Familiarity with the imaging findings in the appropriate clinical setting may result in a heightened level of awareness of this infection and, consequently, in earlier diagnosis and treatment. © The Author(s) 2014.

    Systemic infection caused by Candida species is the fourth leading cause of nosocomial bloodstream infection in modern hospitals and carries high morbidity and mortality despite antifungal therapy. A recent surge of immunological studies in the mouse models of systemic candidiasis and the parallel discovery and phenotypic characterization of inherited genetic disorders in antifungal immune factors that are associated with enhanced susceptibility or resistance to the infection have provided new insights into the cellular and molecular basis of protective innate immune responses against Candida. In this review, the new developments in our understanding of how the mammalian immune system responds to systemic Candida challenge are synthesized and important future research directions are highlighted.

Abnormalities were detected in every individual examined. /sup 99m/Tc-sulfur colloid scintigraphy revealed ''cold'' areas in the liver or spleen. With /sup 67/Ga scintigraphy, these areas were ''cold'' in some individuals and ''hot'' in others. Gray-scale ultrasound demonstrated hypoechoic lesions with central areas of increased echogenicity in hepatic involvement, and hypoechoic replacement of the spleen in splenic involvement. CT in one patient revealed low-density areas without contrast enhancement within the hepatic parenchyma and unsuspected renal involvement.

    1987-01-01

    From the features of two cases, the authors stress the usefulness of the scintigraphy as regards to the diagnosis of visceral candidial abscesses. Such fungal localisations are not unfrequent, especially in immunodeficient patients (haematologic malignancies undergoing chemotherapy, lupus, serious visceral illness...). The positive diagnosis is uneasy because of non-specific clinical features and frequent negative blood cultures. Splenic localisation is the most likely. Citrate Gallium scintigraphy together with splenic labelled RBC scan enables us to give a precise view of the splenic involvment and even of the abdominal extension of the fungal abscess. From the literature review and these two cases, the excellent adequacy of the scintigraphy to the follow-up of systemic candidiasis is underlined and is compared to other usual morphological studies such as US scan and CT examination. In both cases, the diagnosis is fully confirmed by mycological examination.

    Infants treated in neonatal intensive care units suffer an increased risk for invasive candidiasis, but the diagnosis is sometimes difficult. d-arabinitol is a metabolite of most pathogenic Candida species. An elevated urine d-arabinitol/l-arabinitol (DA/LA) ratio is a sensitive sign of invasive candidiasis in children with cancer, but the method has not been previously evaluated for newborn infants. We therefore enrolled 117 infants in a neonatal intensive care unit, and 411 urine samples we...

    2007-01-01

    Adherence to the epithelial surface and tissue invasion represent the major steps in the pathogenesis of candida infection. Grossly, localized (superficial) candidiasis shows well circumscribed white patches, whereas invasive (systemic) candidiasis is characterized by abscess formation. Polymorphonuclear neutrophil cells accompany filamentous and yeast forms of Candida sp. in localized infection. Fungal abscesses demonstrate central necrosis, surrounded by a dense suppurative infiltrate. A granulomatous response may be observed. To identify the infectious agents, a combined cytologic and histopathological approach is recommended.

    Full Text Available Background: Oral candidiasis is increasingly seen among hospitalized patients and is usually treated empirically. It can be the marker of systemic infection. Antifingal resistance is one of the emerging problems in candidiasis. Aim and Objectives: To study the distribution pattern of various Candida species among hospitalised patients with oral candidiasis, to detect the antifungal resistance among Candida and to assess the possible risk factors associated with those patients. Methods: Out of 300 patients screened, oral thrush material was collected from 36 patients having oral candidiasis. Candida spp. were isolated and identified. Antifungal susceptibility test was performed by disk diffusion method. Results: Candida albicans was the most frequently isolated species (64%. Highest resistance was seen with ketoconazole (18%. Except one C. tropicalis, all the isolates were sensitive to amphotericin B. All the patients were on broad spectrum antibiotic treatment. Diabetes mellitus was seen in 50 % of the patients. Other predisposing factors include tuberculosis, COPD, cancer and steroid treatment. Conclusion: Eventhough there is progressive shift from a predominance of C. albicans to non-albicans Candida species in candidiasis, C. albicans remains as the most important pathogen in oral candidiasis. Since azole resistance is increasing, accurate identification of Candida spp. and antifungal susceptibility testing is crucial for patient management and for facilitating hospital control measures.

    Ozone is highly valued for various therapeutic applications such as antimicrobial, antihypoxic, analgesic, and immunostimulating for more than a century in the medical profession. Ozone therapy is now gaining a strong foothold in dentistry. Ozone has bactericidal, fungicidal, and virucidal properties. Oral candidiasis is one of the most common opportunistic fungal infections of the oral cavity. Hence, a study was conducted to evaluate and compare the ability of ozonated water and topical clotrimazole in reducing the Candidal species colony-forming unit (CFU) count in oral candidiasis. The study included 40 candidiasis patients of either sex aged between 18 and 60 years attending the Department of Oral Medicine and Radiology. The patients were randomly assigned to either topical ozone therapy or topical clotrimazole groups. Salivary Candidal CFU counts were assessed during and after the treatments. There was gradual but significant reduction in Candidal CFU count in both groups. At the end of the treatment, Candidal CFU count reduction in ozone group (60.5% reduction) was more than the clotrimazole group (32.3% reduction). 14 patients (70%) with candidiasis in ozone group were reduced to 6 (30%) whereas only 8 patients (40%) out of 13 (65%) in clotrimazole group, although intergroup comparison was not statistically significant. Ozone therapy was much more effective in reducing the patients with candidiasis to a state of carriers. These findings suggest that ozonated water might be useful to treat oral candidiasis.

    Full Text Available Curtis D Collins1, Sarah Cookinham2, Jeannina Smith21Department of Pharmacy Services, 2Department of Medicine, Division of Infectious Disease, University of Michigan Health System, Ann Arbor, MI, USAAbstract: Oropharyngeal candidiasis is a very common localized infection of the mucus membranes of the oropharynx that is most commonly caused by the patient's own commensal Candida albicans. It is the most common opportunistic infection affecting patients with the human immunodeficiency virus (HIV and is also quite common in patients with hematological malignancies. Effective treatment options are of high importance given the worldwide incidence of these disease states and the potential for development of oropharyngeal candidiasis in these patients. Various systemic and topical treatment options for patients with oropharyngeal candidiasis have existed for many years. Miconazole buccal tablets have recently been approved by the US Food and Drug Administration for the treatment of oropharyngeal candidiasis. Clinical trials have demonstrated noninferiority in the treatment of oropharyngeal candidiasis when compared with clotrimazole troches in patients with HIV and against miconazole gel in patients with head and neck cancer. Miconazole buccal tablets exhibit few drug interactions because of low systemic absorption and are generally well tolerated with a safety profile similar to comparators. The once-daily dosing schedule may improve patient adherence compared with topical alternatives; however, the cost of therapy may be a barrier for some patients and should be considered by prescribers compared with alternative treatments.Keywords: esophageal candidiasis, miconazole, antifungal agents

Among patients who presented clinical manifestations of oral candidiasis (n = 24, 83.3% (n = 20 belonged to the group that wore dentures, while only 16.7% (n = 4 belonged to the control group. Elderly patients with diabetes had 4.4 times higher estimated risk of developing oral candidiasis when compared with individuals without this condition. There was no statistically significant association between being user prostheses and have diabetes with the onset of candidiasis. No statistically significant association was determined between xerostomia, use of prosthesis and oral candidiasis. The use of prosthetics and poor oral hygiene in elderly patients predisposes to the development of oral candidiasis.

    Development of oropharyngeal candidiasis is a frequently reported adverse effect of inhaled corticosteroid use, but the prevalence of esophageal candidiasis is unknown. The aim of this study was to estimate the prevalence of esophageal candidiasis among patients treated with an inhaled corticosteroid, fluticasone propionate. Upper GI endoscopy was performed on 49 patients treated with inhaled fluticasone propionate to examine the prevalence of esophageal candidiasis. Of the patients, 36 had bronchial asthma and 13 had chronic obstructive pulmonary disease. To compare the prevalence with control patients, upper GI endoscopy was performed on 700 consecutive patients without malignancy or immunosuppression. The prevalence of esophageal candidiasis was 37% among patients treated with inhaled fluticasone propionate, whereas only 0.3% of the control patients had the infection. The prevalence was especially high among patients with diabetes mellitus or those who were treated with a high dose of inhaled fluticasone propionate. Moreover, a reduction in the daily dose of inhaled fluticasone propionate eliminated the infection in four of five patients. Esophageal candidiasis is a common complication of inhaled corticosteroid use.

    Mucocutaneous candidiasis is frequently one of the first signs of human immunodeficiency virus (HIV) infection. Over 90% of patients with AIDS will develop oropharyngeal candidiasis (OPC) at some time during their illness. Although numerous antifungal agents are available, azoles, both topical (clotrimazole) and systemic (fluconazole, itraconazole, voriconazole, posaconazole) have replaced older topical antifungals (gentian violet and nystatin) in the management of oropharyngeal candidiasis in these patients. The systemic azoles, are generally safe and effective agents in HIV-infected patients with oropharyngeal candidiasis. A constant concern in these patients is relapse, which is dependent on the degree of immunosuppression commonly seen after topical therapy, rather than with systemic azole therapy. Candida esophagitis (CE) is also an important concern since it occurs in more than 10% of patients with AIDS and can lead to a decrease in oral intake and associated weight loss. Fluconazole has become the most widely used antifungal in the management of mucosal candidiasis. However, itraconazole and posaconazole have similar clinical response rates as fluconazole and are also effective alternative agents. In patients with fluconazole-refractory mucosal candidiasis, treatment options now include itraconazole solution, voriconazole, posaconazole, and the newer echinocandins (caspofungin, micafungin, and anidulafungin).

Case presentation: An 87-year-old man presented with intractable hiccups. Although the patient was immunocompetent, he used proton pump inhibitors. An esophagogastroduodenoscopy revealed several white deposits throughout the esophagus and extensive white deposits in the midesophageal diverticulum. A mucosal culture showed candidiasis, which was suspected to be the cause of the intractable hiccups. After oral fluconazole had been prescribed, the candidiasis resolved and the hiccups improved. Therefore, we concluded that esophageal diverticular candidiasis was the cause of his intractable hiccups. Conclusion: Physicians should consider esophageal candidiasis as one of the differential diagnoses for intractable hiccups, even in immunocompetent adults.

    OBJECTIVE: Neonatal invasive candidiasis is associated with significant morbidity and mortality. We describe the association between invasive candidiasis and changes in use of antifungal prophylaxis, empirical antifungal therapy, and broad-spectrum antibacterial antibiotics over time. METHODS: We examined data from 709 325 infants at 322 NICUs managed by the Pediatrix Medical Group from 1997 to 2010. We determined the cumulative incidence of invasive candidiasis and use of antifungal prophylaxis, broad-spectrum antibacterial antibiotics, and empirical antifungal therapy by year. RESULTS: We identified 2063 (0.3%) infants with 2101 episodes of invasive candidiasis. Over the study period, the annual incidence of invasive candidiasis decreased from 3.6 episodes per 1000 patients to 1.4 episodes per 1000 patients among all infants, from 24.2 to 11.6 episodes per 1000 patients among infants with a birth weight of 750–999 g, and from 82.7 to 23.8 episodes per 1000 patients among infants with a birth weight candidiasis in the NICU decreased over the 14-year study period. Increased use of fluconazole prophylaxis and empirical antifungal therapy, along with decreased use of broad-spectrum antibacterial antibiotics, may have contributed to this observation.

    Candidiasis is a fungal infection caused by yeasts that belong to the genus Candida. There are over twenty species of Candida yeasts that can cause infection in humans, the most common of which is Candida albicans. Candida yeasts normally reside in the intestinal tract and can be found on mucous membranes and skin without causing infection; however, overgrowth of these organisms can cause symptoms to develop. Presence of other diseases that compromises the patient's immunity makes it more difficult to treat. Candidiasis is majorly divided into superficial infections (oral or vaginal) and systemic infections, also known as invasive candidiasis. The conventional therapeutic modalities used to treat candidiasis are associated with several side effects that limits the dose and dosing frequency. Development of novel drug delivery systems for reduction in dose and alleviation of side effects is an important strategy to improve the clinical efficacy and patient acceptability. This review gives a bird's eye view of the classification and current therapeutic regime of candidiasis. It presents the varied types of drug delivery systems that have been exploited for delivery of antifungal agents with measurable benefits. It also touches upon echinocandins a relatively new class of drugs that are amenable for translation into novel dosage forms with application against biofilm producing and fluconazole resistant strains contributing to a better therapeutic management of candidiasis.

    Many of the molecular pathways associated with psoriasis pathogenesis are also involved in host defense mechanisms that protect against common pathogens. Candida can stimulate the production of cytokines that trigger or exacerbate psoriasis, and many systemic psoriasis treatments may put patients at increased risk for developing oral, cutaneous, and genitourinary candidiasis. Therefore, dermatologists should regularly screen patients with psoriasis for signs of Candida infection, and take steps to effectively treat these infections to prevent worsening of psoriasis symptoms. This review provides an overview of candidiasis epidemiology in patients with psoriasis, followed by a primer on the diagnosis and treatment of superficial Candida infections, with specific guidance for patients with psoriasis. Candidiasis in patients with psoriasis typically responds to topical or oral antifungal therapy. While biologic agents used to treat moderate-to-severe psoriasis, such as tumor necrosis factor-α inhibitors and interleukin-17 inhibitors, are known to increase patients' risk of developing localized candidiasis, the overall risk of infection is low, and candidiasis can be effectively managed in most patients while receiving systemic psoriasis therapies. Thus, the development of candidiasis does not usually necessitate changes to psoriasis treatment regimens.

    Guidelines for the management of patients with invasive candidiasis and mucosal candidiasis were prepared by an Expert Panel of the Infectious Diseases Society of America. These updated guidelines replace the previous guidelines published in the 15 January 2004 issue of Clinical Infectious Diseases and are intended for use by health care providers who care for patients who either have or are at risk of these infections. Since 2004, several new antifungal agents have become available, and several new studies have been published relating to the treatment of candidemia, other forms of invasive candidiasis, and mucosal disease, including oropharyngeal and esophageal candidiasis. There are also recent prospective data on the prevention of invasive candidiasis in high-risk neonates and adults and on the empiric treatment of suspected invasive candidiasis in adults. This new information is incorporated into this revised document.

    Multifocal cystic lung disease in infants is most commonly congenital, and is managed surgically with perioperative mechanical ventilation. Multifocal cystic lung disease in infants may be due to tuberculosis. We report a young infant with tubercular multifocal cystic lung disease and respiratory failure. The initial chest imaging revealed diffuse nodular infiltrates. Soon after admission he required conventional mechanical ventilation for respiratory failure. The bronchoalveolar lavage fluid grew Mycobacterium tuberculosis in culture. Subsequent chest imaging showed progression to multifocal cystic lung disease. The ventilation mode was changed to high-frequency oscillatory ventilation (HFOV) due to persistent CO(2) retention in the presence of cystic lung disease. The cystic lung disease reversed with antitubercular treatment and prolonged HFOV with slow wean.

    Background: Data on safety and efficacy of voriconazole for invasive aspergillosis (IA) and invasive candidiasis/esophageal candidiasis (IC/EC) in pediatric patients are limited. Methods: Patients aged 2–voriconazole. Patients followed dosing regimens based on age, weight and indication, with adjustments permitted. Treatment duration was 6–12 weeks for IA patients, ≥14 days after last positive Candida culture for IC patients and ≥7 days after signs/symptoms resolution for EC patients. Primary analysis for both the studies was safety and tolerability of voriconazole. Secondary end points included global response success at week 6 and end of treatment (EOT), all-causality mortality and time to death. Voriconazole exposure–response relationship was explored. Results: Of 53 voriconazole-treated pediatric patients (31 IA; 22 IC/EC), 14 had proven/probable IA, 7 had confirmed IC and 10 had confirmed EC. Treatment-related hepatic and visual adverse events, respectively, were reported in 22.6% and 16.1% of IA patients, and 22.7% and 27.3% of IC/EC patients. All-causality mortality in IA patients was 14.3% at week 6; no deaths were attributed to voriconazole. No deaths were reported for IC/EC patients. Global response success rate was 64.3% (week 6 and EOT) in IA patients and 76.5% (EOT) in IC/EC patients. There was no association between voriconazole exposure and efficacy; however, a slight positive association between voriconazole exposure and hepatic adverse events was established. Conclusions: Safety and efficacy outcomes in pediatric patients with IA and IC/EC were consistent with previous findings in adult patients. PMID:27636722

    Intraductal papillary mucinous neoplasms of the pancreas are defined as mucin-producing neoplasms arising in the main pancreatic duct (main duct type), its major branches (branch duct type), or in both (mixed type). Intraductal papillary mucinous neoplasms of the pancreas can occur as a single collection of cysts or as multifocal lesions. While subtypes of intraductal papillary mucinous neoplasms of the pancreas are well described in literature, little is known about the importance of multifocal intraductal papillary mucinous neoplasms of the pancreas. This study evaluated the clinicopathologic characteristics of patients with surgically resected, multifocal intraductal papillary mucinous neoplasm of the pancreas. Clinicopathologic features and preoperative imaging of patients resected for multifocal intraductal papillary mucinous neoplasm of the pancreas defined as intraductal papillary mucinous neoplasm of the pancreas occurring in more than just 1 area, from January 2004 to July 2010 at the Department of Surgery, University of Heidelberg were analyzed. Preoperative parameters, including number of cysts, cyst size, presence of nodules, and epidemiologic data, were assessed and compared to patients with unifocal intraductal papillary mucinous neoplasms of the pancreas. Among 287 patients with resected intraductal papillary mucinous neoplasms of the pancreas, 51 patients (17.8%) with multifocal cystic pancreatic lesions were identified by preoperative imaging. The median age of patients with multifocal intraductal papillary mucinous neoplasms of the pancreas was ≥ 68 years (P = .002) compared to patients with unifocal intraductal papillary mucinous neoplasm of the pancreas (median age, 64 years). Thirty-one multifocal intraductal papillary mucinous neoplasms of the pancreas were of mixed type (60.8%), 15 of branch duct type (29.4%), and 5 of main duct type (9.8%). Histologically, 10 multifocal intraductal papillary mucinous neoplasms of the pancreas had low

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

    2017-02-01

    To assess the test-retest reliability of the multifocal photopic negative response (mfPhNR) of normal human subjects. Multifocal electroretinograms were recorded from one eye of 61 healthy adult subjects on two separate days using a Visual Evoked Response Imaging System software version 4.3 (EDI, San Mateo, California). The visual stimulus delivered on a 75-Hz monitor consisted of seven equal-sized hexagons each subtending 12° of visual angle. The m-step exponent was 9, and the m-sequence was slowed to include at least 30 blank frames after each flash. Only the first slice of the first-order kernel was analyzed. The mfPhNR amplitude was measured at a fixed time in the trough from baseline (BT) as well as at the same fixed time in the trough from the preceding b-wave peak (PT). Additionally, we also analyzed BT normalized either to PT (BT/PT) or to the b-wave amplitude (BT/b-wave). The relative reliability of test-retest differences for each test location was estimated by the Wilcoxon matched-pair signed-rank test and intraclass correlation coefficients (ICC). Absolute test-retest reliability was estimated by Bland-Altman analysis. The test-retest amplitude differences for neither of the two measurement techniques were statistically significant as determined by Wilcoxon matched-pair signed-rank test. PT measurements showed greater ICC values than BT amplitude measurements for all test locations. For each measurement technique, the ICC value of the macular response was greater than that of the surrounding locations. The mean test-retest difference was close to zero for both techniques at each of the test locations, and while the coefficient of reliability (COR-1.96 times the standard deviation of the test-retest difference) was comparable for the two techniques at each test location when expressed in nanovolts, the %COR (COR normalized to the mean test and retest amplitudes) was superior for PT than BT measurements. The ICC and COR were comparable for the BT/PT and

  11. The Quest for Spectacle Independence: A Comparison of Multifocal Intraocular Lens Implants and Pseudophakic Monovision for Patients with Presbyopia.

    2017-01-01

    We performed a literature review comparing multifocal intraocular lens (IOL) implantation with pseudophakic monovision to treat presbyopia. Multifocal IOLs utilize refractive or diffractive principles to treat both distance and near vision, with a single lens implant. Monovision uses traditional monofocal lens implants to treat the dominant eye for emmotropia, and the non-dominant eye for myopia. This planned anisometropia is designed to enhance intermediate or near vision. Generally, distance vision was similar with both types of lens implantation, near vision was better with multifocal IOLs, and intermediate vision appeared to be better in the monovision group. For patients requiring cataract surgery, both multifocal IOLs and monovision appear to address presbyopia with a high level of patient satisfaction. More patients reported complete spectacle independence with multifocal IOLs, but more glare and halos were reported by multifocal IOL patients as well.

    Photodynamic therapy (PDT) has been used in recent years to deal with fungal infections because of the prevalence of fungi resistance to drugs. However, PDT for gastrointestinal fungal infection has not been reported. This study was conducted to assess the potential of PDT to deal with esophageal candidiasis. Two male patients with histological evidence of esophageal candidiasis coexisting with esophageal cancer were included in this retrospective study. Both patients were treated with PDT. This treatment was repeated at least 1month after the initial PDT if the patient still had residual cancer or esophageal candidiasis. Short-term efficacy was evaluated on the basis of endoscopy and histology findings. Further follow-up data were obtained from endoscopy results or telephone conversation. The esophageal candidiasis located 21-24cm and 25-28cm from the incisors of case 1 reached complete remission after one and two PDT sessions, respectively. The esophageal cancer coexisting with esophageal candidiasis located 21-24cm from the incisors reached complete remission after two PDT sessions. No recurrence was found at a 14-month follow-up. The esophageal cancer located 30-35cm from the incisors reached partial response after three PDT sessions. Both of the esophageal candidiasis and the coexisting esophageal cancer at 23-26cm from the incisors of case 2 reached complete remission and the esophageal cancer at 34-37cm from the incisors reached complete remission after one PDT session. No recurrence was found at a 24-month follow-up. There were no serious adverse events found in either of the two cases. Results of this preliminary study indicate that PDT may be a potential method to deal with esophageal candidiasis. Copyright © 2013 Elsevier B.V. All rights reserved.

  13. Invasive Candidiasis in Various Patient Populations: Incorporating Non-Culture Diagnostic Tests into Rational Management Strategies

    Mortality rates due to invasive candidiasis remain unacceptably high, in part because the poor sensitivity and slow turn-around time of cultures delay the initiation of antifungal treatment. β-d-glucan (Fungitell) and polymerase chain reaction (PCR)-based (T2Candida) assays are FDA-approved adjuncts to cultures for diagnosing invasive candidiasis, but their clinical roles are unclear. We propose a Bayesian framework for interpreting non-culture test results and developing rational patient management strategies, which considers test performance and types of invasive candidiasis that are most common in various patient populations. β-d-glucan sensitivity/specificity for candidemia and intra-abdominal candidiasis is ~80%/80% and ~60%/75%, respectively. In settings with 1%–10% likelihood of candidemia, anticipated β-d-glucan positive and negative predictive values are ~4%–31% and ≥97%, respectively. Corresponding values in settings with 3%–30% likelihood of intra-abdominal candidiasis are ~7%–51% and ~78%–98%. β-d-glucan is predicted to be useful in guiding antifungal treatment for wide ranges of populations at-risk for candidemia (incidence ~5%–40%) or intra-abdominal candidiasis (~7%–20%). Validated PCR-based assays should broaden windows to include populations at lower-risk for candidemia (incidence ≥~2%) and higher-risk for intra-abdominal candidiasis (up to ~40%). In the management of individual patients, non-culture tests may also have value outside of these windows. The proposals we put forth are not definitive treatment guidelines, but rather represent starting points for clinical trial design and debate by the infectious diseases community. The principles presented here will be applicable to other assays as they enter the clinic, and to existing assays as more data become available from different populations. PMID:29376927

    Infants treated in neonatal intensive care units suffer an increased risk for invasive candidiasis, but the diagnosis is sometimes difficult. D-arabinitol is a metabolite of most pathogenic Candida species. An elevated urine D-arabinitol/L-arabinitol (DA/LA) ratio is a sensitive sign of invasive candidiasis in children with cancer, but the method has not been previously evaluated for newborn infants. We therefore enrolled 117 infants in a neonatal intensive care unit, and 411 urine samples were obtained on filter paper. The DA/LA ratio was measured by gas chromatography-mass spectrometry. For 81 infants with no suspicion of superficial or invasive candidiasis, the urine DA/LA ratio was 2.7 +/- 0.7 (mean +/- standard deviation [SD]). The upper cutoff level was set at 4.8 (mean plus 3 SD). Of 22 infants with mucocutaneous candidiasis and not given systemic antifungal treatment, two had elevated DA/LA ratios, which normalized after removal of intravascular catheters. Eight other infants were given empiric antifungal treatment but had negative cultures; five of these had repeatedly elevated DA/LA ratios. Six infants with culture-positive invasive candidiasis all had one or more samples with elevated ratios. For seven infants, three with suspected and four with confirmed invasive candidiasis (for which follow-up samples were available), ratios normalized during antifungal treatment. In conclusion, urine DA/LA ratio determination is a rapid test and can be used for newborns. It is possibly more sensitive than fungal blood cultures in the diagnosis of invasive candidiasis and can also be used for monitoring the effect of antifungal treatment.

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

    To evaluate multifocal intraocular lens (MIOL) implantation in children. This is a retrospective study evaluating refractive, visual and safety results of MIOL in pediatric cataract surgery. Average follow-up was 25.73 ± 10.5 months. Surgery included 12 o'clock clear corneal incision, anterior capsulorhexis, lens material aspiration and MIOL implantation (SN6AD3; Alcon). We included 34 cataract eyes of 26 pediatric patients aged 2-15 years, of which 14 (54%) were unilateral. Best near visual acuity (BNVA) and best distance visual acuity (BDVA) improved significantly in 100% of eyes (p = 0.0001). BDVA was above 0.8 in 31.25% (5/16) of bilateral cases. Significant stereopsis improvement was observed postoperatively in bilateral cases only (p = 0.01). MIOL implantation is a safe alternative to monofocal pseudophakia for pediatric cataract with a very low complication rate. Significant BNVA, BDVA and stereopsis improvement can be achieved, particularly in bilateral cases. This study shows significant BDVA, BNVA and stereopsis improvement, especially in bilateral cases, after MIOL implantation for pediatric cataracts. © 2013 S. Karger AG, Basel.

    We present a laser scanning microscope capable of producing multiple focal volumes. These volumes can be displaced vertically, to acquire simultaneous images from multiple planes, or superimposed at the same depth but with different polarization states. We call this last implementation, differential multiphoton laser scanning microscopy (dMPLSM). To our knowledge, this constitutes the first report of a multifocal microscope with this capacity. The microscope is able to take images in different modalities, two-photon excited fluorescence, second, and third harmonic generation. In this work, we demonstrate several capabilities of our microscope: simultaneous acquisition of two and six images from two focal planes separated by several microns, and a pair of simultaneous images taken at the same focal plane but with two different polarizations. Some potential applications include following microorganism motion, studies of phase matching in microscopic environments, studies of blood flow, etc. The microscope is based on a pulsed ultrafast laser. The pulses are split, manipulated and recombined in an interlaced pattern in order to generate a sequence of pulses with different divergences, and possibly different polarizations. This pulse train is sent to the objective and focused at different depths. The signal is recorded using a photoncounting photomultiplier tube. Images from different foci are separated using time demultiplexing based on a low cost field programmable gate array. The use of a single element detector, instead of a multi-element (CCD camera), allows for imaging of scattering media. The use of photon counting leads to lower signal to noise ratio in the images.

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

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

    Chronic recurrent multifocal osteomyelitis (CRMO) is a little known inflammatory bone disease occurring primarily in children and adolescents. Delays in referral and diagnosis may lead to prolonged courses of antibiotics with in-patient care, unnecessary radiation exposure from multiple plain radiographs or bone scans and repeated surgery including bone biopsies. Children (aged < 18 years) diagnosed with CRMO between January 2005 and December 2012, reviewed at Bristol Royal Hospital for Children were included and all available data collected. Information regarding CRMO was sent to all orthopaedic surgeons in the region in 2009. The aim of the study was to examine the features of the cohort, to examine the length of time to diagnosis and to explore the criteria used for diagnosis with and without biopsy. Over an 8 year period, 41 patients were diagnosed with CRMO. Symptom onset occurred at a median of 9 years of age and time to diagnosis had a median of 15 months (range 0-92). Correlation coefficient analysis for time to diagnosis by year showed statistical significance with a decreasing trend. From the cohort data, diagnostic criteria were developed; applied retrospectively, 34 (83 %) children may have been diagnosed using the criteria, without a biopsy. The data suggest that increasing knowledge of this condition may shorten time to diagnosis. Use of the Bristol diagnostic criteria by an experienced clinician may obviate the need for biopsy in some patients.

    To determine the effect of flash fundus photography (FFP) on the multifocal electroretinogram (mfERG). Ten subjects underwent mfERG testing on three separate dates. Subjects received either mfERG without FFP, mfERG at 5 and 15 min after FFP, or mfERG at 30 and 45 min after FFP on each date. The FFP groups received 10 fundus photographs followed by mfERG testing, first of the right eye then of the left eye 10 min later. Data were averaged and analyzed in six concentric rings at each time point. Average amplitude and implicit times of the N1, P1, and N2 peaks for each concentric ring at each time point after FFP were compared to baseline. Flash fundus photography did not lead to a significant change of amplitude or implicit times of N1, P1, or N2 at 5 min after light exposure. These findings suggest that it is acceptable to perform mfERG testing without delay after performance of FFP.

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

She was visually asymptomatic, with normal fundus appearance, normal colour vision testing findings, 20/20 visual acuity in both eyes, and only mild central bilateral defects on 10-2 perimetry. Multifocal electroretinography (mfERG showed low density values for ring 1 in both eyes. Because the patient had not previously responded to alternative treatments and in consultation with her physician, the hydroxychloroquine dose was reduced to 200 mg four days/week. Four serial mfERGs performed at 4, 18, 25, and 34 months after dose reduction showed a progressive improvement in the definition and density of the responses until they were normalized at the third mfERG (25 months after hydroxychloroquine dose reduction. The fourth and final mfERG at 34 months confirmed the recovery in both eyes. Perimetry defects were mostly normalized. These results demonstrate the importance of mfERG for the safe management of patients under long-term hydroxychloroquine treatment.

    Elastography is a non-invasive imaging technique that images tissue stiffness. Given the well known association between tissue stiffness and cancer type, it can be used effectively for breast cancer detection and assessment. This study involves system development of a real-time ultrasound based elastography system designed for assessing multifocal breast cancer. This system is capable of imaging breast tissues absolute Young's Moduli. The imaging involves tissue mechanical stimulation, displacement and force data acquisition followed by Young's modulus reconstruction using a constrained full-inversion approach. This approach utilizes axial strain field and surface force data acquired by the elastography system via an iterative numerical process to construct the breast tissue Young's modulus. The strain field is obtained using an ultrasound machine equipped with an RF signal processing module. For force data acquisition, a system comprised of two load cells attached at the ultrasound system probe was employed. Each iteration of the reconstruction algorithm involves tissue stress calculation followed by tissue Young's modulus updating. To speed up the reconstruction process, a novel accelerated finite element method developed in our laboratory was used for stress calculation. To validate the proposed method, tissue-mimicking phantom studies were conducted. These studies showed promising results paving the way for further validation and application in a clinical setting.

    Full Text Available We present one case of a metachronous, atypical, multifocal renal oncocytoma with a concomitant chromophobe renal cell carcinoma (RCC of the contralateral side and one case of bilateral and multifocal oncocytomas. Oncocytomas are benign renal tumours that rarely appear bilateral or multifocal or with coexisting RCC. A common pathogenic denominator of oncoytomas and RCC is being discussed. The first case was a 63 years old patient presenting with a history of nephrectomy for a pT1 G1 pN0 R0 papillary RCC 4 years prior to presentation, showed two tumours of a singular kidney. Upon nephron-sparing surgery one typical and one atypical oncocytoma with an invasion of the perinephric fat were found. Comparative genomic hybridisation was performed. Both tumours revealed genetic alterations with loss of genetic material on chromosome 1p. The second case was a 62 years old patient presenting with multifocal and bilateral renal tumours of undeclared dignity upon imaging. During open exploration all tumours could be removed by nephron-sparing surgery and were identified as oncocytomas. Again comparative genomic hybridisation was performed. All 4 tumours revealed genetic alterations with loss of genetic material on chromosome 1p, one of the tumours an additional loss of chromosome 10.

    Papillary thyroid cancer (PTC) often presents as multifocal tumor;, however, whether multifocality is associated with poor prognosis remains controversial. The aims of this retrospective study were to identify the characteristics of PTC with multifocal tumors and evaluate the association between the location and prognosis. We reviewed the medical records of 496 patients who underwent total thyroidectomy for PTC. Patients were classified as three groups: N1 (solitary tumor), N2 (2 or more foci within unilateral lobe of thyroid), and N3 (bilateral tumors, at least one tumor focus for each lobe of thyroid). We analyzed the differences of clinicopathologic features and clinical outcomes among the three groups. Cox regression model was used to assess the relation between the different locations of multifocal tumors and prognosis. Although the differences of clinicopathologic features such as the size of tumor, extrathyroidal extension, and cervical lymph node metastasis were not significant among the three groups, the bilateral-multifocality was proved to be an independent risk factor for neck recurrence (hazard ratio (HR) = 4.052, 95 % confidence interval (CI) 2.070-7.933), distant metastasis (HR = 3.860, 95 % CI 1.507-9.884), and cancer death (HR = 7.252, 95 % 2.189-24.025). In addition, extrathyroidal extension (HR = 2.291, 95 % CI 1.185-4.427) and older age >45 years (HR = 6.721, 95 % CI 2.300-19.637) were also significant predictors for neck recurrence and cancer death, respectively. Therefore, bilateral-multifocality as an indicator for more extensive tumor location could be used to assess the risk of recurrence and mortality in PTC. Given the poor prognosis associated with bilateral-multifocality and other risk factors, aggressive therapy and intensive follow-up were recommended for PTC patients with them.

    The purpose of this study was to assess visual performance and patient satisfaction with two presbyopic soft contact lens modalities. A crossover study of 38 patients with presbyopia was conducted. Patients were randomized first into either multifocal (Bausch & Lomb SofLens Multifocal) or monovision (SofLens 59) for 1 month. Visual performance was measured with high- and low-contrast visual acuity at distance and near and near stereoacuity. Patients' satisfaction was measured by the National Eye Institute Refractive Error Quality of Life Instrument questionnaire and by recording the patient's final lens preference. Patients maintained at least 20/20 binocular vision with both multifocal (MF) and monovision (MV) contact lenses under high-contrast conditions at distance and near. Under low-contrast conditions, patients lost less than a line of vision from the best spectacle correction to either multifocal or monovision contact lens correction at distance (pMF = 0.001, pMV = 0.006). Under low-contrast conditions at near, multifocal wearers lost five to six letters and monovision wearers lost two letters of vision (pMF contact lenses (p = 0.002). On the NEI-RQL, patients reported worse clarity of vision (pMF = 0.01, pMV contact lens wear (pMF contact lenses, and 24% preferred monovision contact lenses (p = 0.001). The majority of our patients preferred multifocals to monovision, most likely because the Bausch & Lomb SofLens Multifocal provides excellent visual acuity without compromising stereoacuity to the same degree as monovision.

    To study the frequency of multifocality in well-differentiated non-medullary thyroid carcinomas and correlate it with various epidemiological factors, as well as with patients' survival. A retrospective study was conducted on 80 patients who underwent total thyroidectomy from January 1985 to December 2004 in the First Department of Surgery of University General Hospital of Alexandroupolis, Democritus University of Thrace, Greece, for well-differentiated non-medullary thyroid cancer (papillary and follicular). Patients' medical records and demographics, including age, gender, histological type (papillary, follicular), multiple foci of tumors, overall and specific survival were analyzed. Multifocality was established in 17/80 patients (21,25%). Multifocal tumors were found in 4/20 male patients (20%) and 13/60 female ones (21,67%), percentages which are almost identical. Increased rates of multifocal tumors were found in the age groups of 20-29, 30-39 and 70-79 years old, while low rates were documented in the age groups of 0-9, 10-19 and 60-69 years old. Follicular tumors had a 20% rate, similar to papillary tumors (22,2%), and an impressive multifocal rate of mixed papillary-follicular neoplasms (75%) was found. Finally, survival was not found to be influenced by the multifocality of the tumor, under the prerequisition that total thyroidectomy is applied. Multifocality should not be considered as a "privilege" of papillary thyroid tumors, but as a privilege of thyroid carcinomas in general. If total thyroidectomy is applied in all benign and malignant thyroid diseases, the presence of multiple foci does not affect the prognosis and the survival of the patients.

  20. Systemic vs. Topical Therapy for the Treatment of Vulvovaginal Candidiasis

    Directory of Open Access Journals (Sweden)

    1994-01-01

    Full Text Available It is estimated that 75% of all women will experience at least 1 episode of vulvovaginal candidiasis (VVC during their lifetimes. Most patients with acute VVC can be treated with short-term regimens that optimize compliance. Since current topical and oral antifungals have shown comparably high efficacy rates, other issues should be considered in determining the most appropriate therapy. It is possible that the use of short-duration narrow-spectrum agents may increase selection of more resistant organisms which will result in an increase of recurrent VVC (RVVC. Women who are known or suspected to be pregnant and women of childbearing age who are not using a reliable means of contraception should receive topical therapy, as should those who are breast-feeding or receiving drugs that can interact with an oral azole and those who have previously experienced adverse effects during azole therapy. Because of the potential risks associated with systemic treatment, topical therapy with a broad-spectrum agent should be the method of choice for VVC, whereas systemic therapy should be reserved for either RVVC or cases where the benefits outweigh any possible adverse reactions.

  1. Canadian Clinical Practice Guidelines for Invasive Candidiasis in Adults

    2010-01-01

    Full Text Available Candidemia and invasive candidiasis (C/IC are life-threatening opportunistic infections that add excess morbidity, mortality and cost to the management of patients with a range of potentially curable underlying conditions. The Association of Medical Microbiology and Infectious Disease Canada developed evidence-based guidelines for the approach to the diagnosis and management of these infections in the ever-increasing population of at-risk adult patients in the health care system. Over the past few years, a new and broader understanding of the epidemiology and pathogenesis of C/IC has emerged and has been coupled with the availability of new antifungal agents and defined strategies for targeting groups at risk including, but not limited to, acute leukemia patients, hematopoietic stem cell transplants and solid organ transplants, and critical care unit patients. Accordingly, these guidelines have focused on patients at risk for C/IC, and on approaches of prevention, early therapy for suspected but unproven infection, and targeted therapy for probable and proven infection.

    A simple method to establish a murine esophageal candidiasis model that displayed characteristic symptoms of the condition was developed using the sedative agent, chlorpromazine. Mice were immunosuppressed with prednisolone and were given tetracycline hydrochloride. One day later, the mice received chlorpromazine to keep them in a sedated state for about 3 hr. Under the sedated condition, they were infected with 4 x 10(7) viable cells of Candida albicans by intra-esophageal injection with a round-head needle on syringe. From day 3 to day 6 post inoculation, 10(5)-10(6) colony forming units of C. albicans were recovered from the esophageal tube of each mouse and whitish, curd-like patches were observed on most of the inner surface of the tube. Histological examination showed that C. albicans in esophageal lesions grew mainly in mycelial form. In this experimental model, intragastric administration of an itraconazole oral solution (20 mg/kg/day) was clearly effective. This model would provide a useful tool to investigate the pathogenesis of C. albicans esophageal infection and the efficacy of various antifungal agents microbiologically and symptomatically.

    We undertook the first case control study of histologically confirmed esophageal candidiasis (EC). A computer search from July 2012 through February 2015 identified 1,011 esophageal specimens, including 40 cases of EC and 20 controls. The EC incidence was 5.2%; it was associated with immunosuppression and endoscopic white plaques and breaks. Smoking was a predisposing factor, and alcohol was protective. EC had no unique symptoms, and 54% of endoscopic reports did not suspect EC. Important histologic clues included superficial and detached fragments of desquamated and hyper-pink parakeratosis, acute inflammation, intraepithelial lymphocytosis, dead keratinocytes, and bacterial overgrowth. Thirty percent had no neutrophilic infiltrate. Pseudohyphae were seen on H&E in 92.5% (n = 37/40). "Upfront" periodic acid-Schiff with diastase (PAS/D) on all esophageal specimens would have generated $68,333.49 in patient charges. Our targeted PAS/D strategy resulted in $13,044.87 in patient charges (cost saving = 80.9%, $55,288.62). We describe the typical morphology of EC and recommend limiting PAS/D to cases where the organisms are not readily identifiable on H&E and with at least one of the following: (1) ulcer, (2) suspicious morphology, and/or (3) clinical impression of EC.

    This study presents a systematic review of the literature on the etiology of superficial and invasive candidiasis in Mexico reported from 2005 to 2015. The data have shown that Candida albicans is the most prevalent species with an increasing tendency of the non-C. albicans Candida species, as reported in other countries. The use of phenotypical methods in the identification of the yeasts limits the identification at the species level, particularly in species that are part of complexes, this is important because the identification only at the genus level leads to inadequate treatment due to the different susceptibility to the antifungals among species. In addition, this finding reveals the need to implement in clinical laboratories the molecular methods for the correct identification of the species involved, and the antifungal susceptibility tests to prevent the etiological changes associated with a poor therapeutic management.

    Vulvovaginal candidiasis (VVC) is the most common genital infections that are seen every day in clinics. This infection is due to excessive growth of Candida that are normally present in the vagina in small numbers. Diagnosis of VVC is routinely done by direct microscopy of Pap smear samples and searching for the Candida in the Pap smear glass slides. This manual method is subjective, time consuming, labour-intensive and tedious. This study presents a computer-aided diagnostic (CAD) method to improve human diagnosis of VVC. The proposed CAD method reduces the diagnostic time and also can be worked as a second objective opinion for pathologists. Our main objective is detection and extraction of mycelium and conidium of Candida fungus from microscopic images of Pap smear samples. In this regard, the proposed method is composed of three main phases, namely preprocessing, segmentation, feature extraction and classification. At the first phase, bottom-hat filtering is used for elimination of the cervical cells and separating the background. Then decorrelation stretching and colour K-means clustering are used for Candida segmentation. Finally the extracted features used by a decision tree classifier to detect Candida from other parts of smear. The proposed method was evaluated on 200 Pap smear images and showed specificity of 99.83% and 99.62% and sensitivity of 92.18% and 94.53% for detection of mycelium and conidium, respectively. © 2017 The Authors Journal of Microscopy © 2017 Royal Microscopical Society.

    Esophageal candidiasis is associated with conditions that cause an immune depression. It is a defining disease for AIDS, is observed in poorly controlled diabetics, in patients with renal or hepatic failure, in patients with cancer and in subjects using medications causing immunosuppression or broad spectrum antimicrobials. To report the features of 10 immunocompetent patients with esophageal candidiasis. Six males and four females aged between 48 and 82 years, without conditions associated with immunosuppression, in whom an esophageal candidiasis was found on an upper gastrointestinal endoscopy. Delayed skin hypersensitivity to eight antigens, lymphocyte subpopulations, yeast phagocytosis and neutrophil chemotaxis were measured. Six patients had a low CD4 lymphocyte count and seven had a low CD8 count. Seven patients were anergic on skin hypersensitivity challenge. Yeast phagocytosis was abnormal in one patient and neutrophil chemotaxis was abnormal in two. Humoral immunity was normal in all subjects. All patients were treated with oral fluconazole in doses of 150 mg/day for 14 days, with complete resolution of candidiasis in all. Patients with esophageal candidiasis, have frequent alterations of cellular immunity, that must be diagnosed and treated.

    Oropharyngeal candidiasis is a very common localized infection of the mucus membranes of the oropharynx that is most commonly caused by the patient's own commensal Candida albicans. It is the most common opportunistic infection affecting patients with the human immunodeficiency virus (HIV) and is also quite common in patients with hematological malignancies. Effective treatment options are of high importance given the worldwide incidence of these disease states and the potential for development of oropharyngeal candidiasis in these patients. Various systemic and topical treatment options for patients with oropharyngeal candidiasis have existed for many years. Miconazole buccal tablets have recently been approved by the US Food and Drug Administration for the treatment of oropharyngeal candidiasis. Clinical trials have demonstrated noninferiority in the treatment of oropharyngeal candidiasis when compared with clotrimazole troches in patients with HIV and against miconazole gel in patients with head and neck cancer. Miconazole buccal tablets exhibit few drug interactions because of low systemic absorption and are generally well tolerated with a safety profile similar to comparators. The once-daily dosing schedule may improve patient adherence compared with topical alternatives; however, the cost of therapy may be a barrier for some patients and should be considered by prescribers compared with alternative treatments.

    Invasive candidiasis is the 4(th) leading cause of nosocomial bloodstream infection in the US with mortality that exceeds 40% despite administration of antifungal therapy; neutropenia is a major risk factor for poor outcome after invasive candidiasis. In a fatal mouse model of invasive candidiasis that mimics human bloodstream-derived invasive candidiasis, the most highly infected organ is the kidney and neutrophils are the major cellular mediators of host defense; however, factors regulating neutrophil recruitment have not been previously defined. Here we show that mice lacking chemokine receptor Ccr1, which is widely expressed on leukocytes, had selectively impaired accumulation of neutrophils in the kidney limited to the late phase of the time course of the model; surprisingly, this was associated with improved renal function and survival without affecting tissue fungal burden. Consistent with this, neutrophils from wild-type mice in blood and kidney switched from Ccr1(lo) to Ccr1(high) at late time-points post-infection, when Ccr1 ligands were produced at high levels in the kidney and were chemotactic for kidney neutrophils ex vivo. Further, when a 1∶1 mixture of Ccr1(+/+) and Ccr1(-/-) donor neutrophils was adoptively transferred intravenously into Candida-infected Ccr1(+/+) recipient mice, neutrophil trafficking into the kidney was significantly skewed toward Ccr1(+/+) cells. Thus, neutrophil Ccr1 amplifies late renal immunopathology and increases mortality in invasive candidiasis by mediating excessive recruitment of neutrophils from the blood to the target organ.

    Background We describe the incidence, risk factors, and outcomes of invasive candidiasis in infants >1500 g birth weight. Methods We conducted a retrospective cohort study of infants >1500 g birth weight discharged from 305 NICUs in the Pediatrix Medical Group from 2001–2010. Using multivariable logistic regression, we identified risk factors for invasive candidiasis. Results Invasive candidiasis occurred in 330/530,162 (0.06%) infants. These were documented from positive cultures from ≥1 of these sources: blood (n=323), cerebrospinal fluid (n=6), or urine from catheterization (n=19). Risk factors included day of life >7 (OR 25.2; 95% CI 14.6–43.3), vaginal birth (OR 1.6 [1.2–2.3]), exposure to broad-spectrum antibiotics (OR 1.6 [1.1–2.4]), central venous line (OR 1.8 [1.3–2.6]), and platelet count candidiasis had increased mortality (OR 2.2 [1.3–3.6]). Conclusions Invasive candidiasis is uncommon in infants >1500 g birth weight. Infants at greatest risk are those exposed to broad-spectrum antibiotics and with platelet counts of <50,000/mm3.

    OBJECTIVE: To investigate factors that predispose breastfeeding mothers to nipple candidiasis. DESIGN: A retrospective case-control study of women attending the Calgary Breastfeeding Clinic. SETTING: Ambulatory breastfeeding referral centre. PARTICIPANTS: All women (105) who attended the clinic during a 3.5-month study period. All were referred for problems with breastfeeding; 27 (the case group) had positive diagnostic criteria for nipple candidiasis. The other 78 formed a control group. MAIN OUTCOME MEASURE: A patient information sheet, completed while taking a medical history, recorded the presence or absence of four possible predisposing factors. Two infant variables were also noted on physical examination. Patients were diagnosed as having or not having nipple candidiasis on the basis of specific clinical criteria, and statistics on other variables were compared for those with positive and with negative diagnoses. RESULTS: A statistically significant correlation (P antibiotic use (P = 0.036), and nipple trauma (P = 0.001). CONCLUSIONS: Further research is required to establish clear causality. However, we recommend that physicians be suspicious of nipple candidiasis; avoid antibiotics or use the shortest effective course; treat yeast vaginitis during the third trimester and after delivery aggressively; and treat mothers for nipple yeast if babies have oral or diaper candidiasis. Breastfeeding mothers can also be counseled in preventive measures. PMID:8081120

    This study aimed to examine the genotype distribution of Candida albicans and the major genotypes involved in superficial candidiasis. The genotypes of C. albicans isolated from the infection sites of patients with superficial candidiasis (referred to as infection isolates) were analyzed by fragment analysis using 4 microsatellite markers (HIS3, CDC3, CAI and CAIII). Genotypes of the infection isolates were compared with those of C. albicans isolated from oral mucosa of non-candidiasis patients (referred to as oral isolates). Isolates of C. albicans showed 4 major genotypes for HIS3/CAI (" a " for 148 : 148 / 23 : 23," b " for 148 : 160 / 33 : 41," c " for 148 : 164 / 32 : 41 and " d " for 152 : 152 / 18 : 27). The genotypes " a "," b " and " d " were commonly found in oral (4.7, 8.8 and 7.6%, respectively) and infection (6.6, 9.2 and 15.4%, respectively) isolates. No isolates of genotype " c " were isolated from infection sites. The genotype " a " was found in the isolates from patients with genitalia candidiasis. Genotyping of multiple isolates from an individual patient showed that C. albicans from infection sites was genetically homogenous as compared with that of oral isolates, even in the same patient with candidiasis.

Little is known about the mechanisms leading to relapses in otherwise healthy women. Nitric oxide is part of the nonspecific host defense and is increased during inflammation. Nitric oxide levels were measured and the expression of inducible nitric oxide synthase was analyzed in the vagina during an acute episode of recurrent vulvovaginal candidiasis and after treatment with fluconazole. Twenty-eight women with symptoms of recurrent vulvovaginal candidiasis were enrolled together with 31 healthy controls. Nitric oxide was measured with an air-filled 25-mL silicon catheter balloon incubated in the vagina for five minutes and then analyzed by chemiluminescence technique. Vaginal biopsies were analyzed for the expression of inducible nitric oxide synthase. Symptoms and clinical findings were surveyed using a scoring system. The measurements and biopsies were repeated in patients after six weeks of fluconazole treatment. Nitric oxide levels were increased during acute infection (median 352 ppb) compared with controls (median 6 ppb), p candidiasis during acute episodes of infection and decreases after antifungal treatment. The results illustrate the pronounced inflammatory response in recurrent vulvovaginal candidiasis correlating to symptoms of pain and discomfort. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

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

    Full Text Available A retrospective review of the tumor focality and BRAFV600E mutational status of all thyroidectomy cases diagnosed with papillary thyroid carcinoma (PTC between 1/2010 and 7/2013 was performed. A total of 122 cases were included in this study consisting of 65 solitary cases and 57 multifocal cases with a total of 209 tumor nodules. In the multifocal tumors with absent BRAFV600E mutation in the dominant nodule, an additional tumor focus was submitted for testing. The clinicopathologic characteristics of the cases were then compared and analyzed. Significant association with BRAFV600E mutation was driven by previously established unfavorable histologic features such as usual variant, capsular invasion, lymphovascular invasion, extrathyroidal extension, and lymph node metastasis. We did not establish this association with tumor multifocality in this study. Although more cases of mPTC (multifocal papillary thyroid carcinoma had BRAFV600E mutation in comparison with the solitary cases (56 vs 44%, we did not find a significant difference between the two groups (p = 0.0689. Furthermore, at least one of the unfavorable histologic features was also noted in three out of the five multifocal cases with discordant mutations in the two largest nodules. The heterogeneity of BRAFV600E mutational status in mPTC is evident in this study and although it seems prudent to further test additional foci, it appears that in most cases there are already histologic features that support a more aggressive behavior. Selective testing based on histomorphology may be a more practical approach in these cases.

    To investigate the temporal changes in the prevalence of oral candidiasis in a cohort of Spanish human immunodeficiency virus (HIV)-infected individuals, before and after the introduction of highly active antiretroviral therapy (HAART). Retrospective analysis of a clinical database from "Carlos Haya" Hospital, Málaga, Spain, from 1995 to 2000. The prevalence of oral candidiasis was assessed in 807 HIV/AIDS patients and the temporal progression of its major variants evaluated using a linear regression model. Overall oral candidiasis was prevalent in 30.0% to 48.3% of the cohort throughout and no significant variation in its incidence was noted during the study period. Prevalence of erythematous candidiasis increased from 24.5% (1995) to 45.0% (2000) and pseudomembranous candidiasis decreased from 22.4% (1995) to 5.2% (2000) (PHyperplastic candidiasis was not detected in the cohort after the introduction of HAART therapy. Although oral candidiasis in HIV-infected Spanish individuals has not decreased significantly after the introduction of HAART, there appears to be a significant reduction in hyperplastic and pseudomembranous variants of the disease with a compensatory increase in erythematous candidiasis.

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

    Full Text Available Abstract Introduction The majority of multifocal micronodular pneumocyte hyperplasia associated with tuberous sclerosis complex is diagnosed with the classical clinical triad of seizures, mental retardation, and skin lesions. We report a rare case of tuberous sclerosis complex with no classical clinical findings, which was diagnosed through incidental computed tomography findings of multiple nodular lesions of multifocal micronodular pneumocyte hyperplasia. Case presentation A chest computed tomography scan of a 51-year-old Japanese woman showed multiple nodular ground-glass opacities that were not seen on chest X-ray. Video-assisted thoracoscopic surgery was performed. A histological examination demonstrated type II pneumocyte hyperplasia with thickened fibrotic alveolar septa, which was consistent with multifocal micronodular pneumocyte hyperplasia. Brain magnetic resonance imaging displayed multiple cortical tubers, and abdominal computed tomography showed bilateral renal angiomyolipoma. Our patient was finally diagnosed as having tuberous sclerosis complex with multifocal micronodular pneumocyte hyperplasia, although she had no episodes of epilepsy, no skin lesions, and no family history. Conclusions Multifocal micronodular pneumocyte hyperplasia with latent tuberous sclerosis complex should be considered in the differential diagnosis of multiple ground-glass opacities.

    Full Text Available Aims : To determine waveforms of multifocal electroretinogram (mfERG in patients with retinitis pigmentosa (RP contributing significantly to the overall retinal response by using principal components′ analysis. Settings and Design: Prospective, non-randomized, single-visit, observational, case-control study from a single tertiary ophthalmic center. Materials and Methods: Patients with various forms of RP underwent mfERG testing for a period of one year. The first-order kernel responses of RP cases were compared with concurrently recruited healthy controls. Statistical Analysis Used: Parametric data was analyzed using the unpaired t test for differences between the implicit time and amplitudes of cases and controls. Principal components′ analysis was done for each implicit time and amplitude in cases with RP using the Varimax rotation method. Results: From March 2006 to March 2007, 24 cases with typical RP (56%, 47 eyes were included in the final analysis. Their mean age was 33.7 years (19-69 ± 15.5 years. Comparison of latencies and amplitudes among RP cases with log MAR acuity ≤ 0.18 and those > 0.18, revealed significant difference in the implicit time (P1 in Ring 2 only (P=0.028. Two components (predominently from Ring 1 and 2 each contributing 66.8% and 88.8% of the total variance in the data for latencies and amplitudes respectively, were seen. Conclusions : The first two rings of the mfERG contributed to the variance of waveforms in RP, irrespective of the visual acuity and poor visual field results.

    Full Text Available Hepatosplenic candidiasis also known as chronic disseminated candidiasis is a rare manifestation of invasive fungal infection typically observed in patients with acute leukemia in prolonged, deep neutropenia. Immune reconstitution inflammatory syndrome (IRIS is an inflammatory disorder triggered by rapid resolution of neutropenia. Diagnosis and treatment of IRIS are still challenging due to a variety of clinical symptoms, lack of certain diagnostic criteria, and no standards of treatment. The diagnosis of IRIS is even more difficult in patients with hematological malignancies complicated by “probable” invasive fungal infection, when fungal pathogen is still uncertain. We report a case of probable hepatic candidiasis in 4-year-old boy with acute lymphoblastic leukemia. Despite proper antifungal therapy, there was no clinical and radiological improvement, so diagnosis of Candida-related IRIS was made and corticosteroid therapy was added to antifungal treatment achieving prompt resolution of infection symptoms.

    BACKGROUND Graft-site candidiasis rarely develops in solid organ transplant recipients; however, severe life-threatening complications can occur. We report the course of 3 solid organ transplant recipients developing graft-site candidiasis. CASE REPORT All grafts, consisting of 2 kidneys and 1 liver, were procured from a single donor. Patient data were collected from our database. Candida albicans was isolated from a swab taken during multiple-organ recovery. Complications associated with candidiasis occurred in all 3 recipients with preservation of the liver transplant. Both renal transplant recipients had vascular complications, eventually resulting in graft nephrectomy and subsequent return to dialysis. The patients recovered completely without residual effects of their prior fungal infection. CONCLUSIONS Fungal infections in solid organ transplant recipients are rare. Since the sequelae of these infections are serious and usually pertain to more than 1 recipient at a time, antifungal prophylaxis may be warranted in select donors.

    To investigate epidemiologic trends, clinical features and outcome of esophageal candidiasis in the era of highly active antiretroviral therapy in a prospectively monitored population of HIV-infected children and adolescents followed at the National Cancer Institute. The records of all HIV-infected pediatric patients (n = 266) followed between 1995 and 2000 were reviewed for a history of esophageal candidiasis. Proven esophageal candidiasis was defined as clinical plus radiographic and/or endoscopic findings of esophageal candidiasis. Probable esophageal candidiasis was defined as esophageal symptoms that responded promptly to appropriate antifungal therapy. The medical records of all patients fulfilling these criteria were reviewed for demographic, clinical and laboratory features at presentation, as well as therapeutic interventions and outcome. Of the 266 patients 9 (3.4%) had 18 documented episodes of proven (n = 16) or probable (n = 2) esophageal candidiasis. A history of prior mucosal candidiasis was present in 94% of all episodes. The median CD4+ count at the time of diagnosis was 7/microl (range, 0 to 550), and the median viral load was 98000 copies/ml (range, 22916 to 1278933). Concurrent oropharyngeal candidiasis was the most common clinical presentation (72%) followed by fever (55%), odynophagia (50%) and nausea or vomiting (39%). Treatment consisted of antifungal triazoles (61%) or amphotericin B (39%). Clinical cure was achieved in 15 cases, including all patients receiving triazoles. Esophageal candidiasis persists in the subgroup of patients not responding to highly active antiretroviral therapy and in that setting may present without concomitant oropharyngeal candidiasis or typical clinical symptoms, thus underscoring the need for a high index of suspicion in children with very low CD4+ counts.

    Full Text Available Background & aim: Vulvovaginal Candidiasis (VVC is a common disease affecting more than 75% of all women at least once in their lifetime. Various factors, including genetic and immunology factors, plays an important role in this disease. IL-18 is an important cytokine in immune system and has several polymorphisms in the promoter region. This study attempted to evaluate associations between IL-18 gene polymorphisms in patients with acute Vulvovaginal Candidiasis. Methods: In the present case-control study, a total of 100 women with Vulvovaginal Candidiasis and 100 healthy women in Iran were examined. DNA was extracted by saluting out method and Single nucleotide Polymorphisms of the IL-18 gene at positions -607 (C/A and -137 (G/C were analyzed by the Allele-specific PCR method and data were compared in both groups by using Pearson’s chi-square test and to investigate that the genotypes study in the position followed the Hardy-Weinberg equilibrium, was assessed by the Arlequin 3.1. Results: The results of this study showed that the frequency of genotypes of polymorphic position -607 C / A IL-18 genes were not significantly different in patients with vaginal Candidiasis and the control group P> 0.05. On the other hand, in patients ,there was  an association  with a significant increase in the C allele and CC genotype, of the single nucleotide polymorphisms (SNPs at position-137G/C in the IL-18 gene promoter and Vulvovaginal Candidiasis ( P< 0.05 . Conclusion: Due to the fact that an increase in the expression of CC genotype and allele C, can lead to reduction of Interleukin-18 gene promoter activity and according to the impact of that activity of this cytokine can lead to Th1 system, it seems that the promoter activity of this gene may lead to reduced activity of the immune system and as a result be prone to vaginal Candidiasis

    Vulvovaginal candidiasis (VVC) is estimated to be the second most common form of infection after bacterial vaginosis. The ability of probiotics in maintaining and recovering the normal vaginal microbiota, and their potential ability to resist Candidas give rise to the concept of using probiotics for the treatment of VVC. To assess the effectiveness and safety of probiotics for the treatment of vulvovaginal candidiasis in non-pregnant women. We searched the following databases to October 2017: Sexually Transmitted Infections Cochrane Review Group's Specialized Register, CENTRAL, MEDLINE, Embase and eight other databases. We searched in following international resources: World Health Organization International Clinical Trials Registry Platform, ClinicalTrials.gov, Web of Science and OpenGrey. We checked specialty journals, reference lists of published articles and conference proceedings. We collected information from pharmaceutical companies and experts in the field. Randomized controlled trials (RCT) using probiotics, alone or as adjuvants to conventional antifungal drugs, to treat VVC in non-pregnant women. Trials recruiting women with recurrent VVC, coinfection with other vulvovaginal infections, diabetes mellitus, immunosuppressive disorders or taking immunosuppressant medication were ineligible for inclusion. Probiotics were included if they were made from single or multiple species and in any preparation type/dosage/route of administration. Two review authors independently assessed trials for eligibility and quality and extracted data. We resolved any disagreements through consensus. The quality of the evidence was assessed using the GRADE approach. Ten RCTs (1656 participants) met our inclusion criteria, and pharmaceutical industry funded none of these trials. All trials used probiotics as adjuvant therapy to antifungal drugs. Probiotics increased the rate of short-term clinical cure (risk ratio (RR) 1.14, 95% confidence interval (CI) 1.05 to 1.24, 695

    IMPORTANCE Invasive candidiasis in premature infants causes mortality and neurodevelopmental impairment. Fluconazole prophylaxis reduces candidiasis, but its effect on mortality and the safety of fluconazole is unknown. OBJECTIVE To evaluate the efficacy and safety of fluconazole in preventing death or invasive candidiasis in extremely low-birth-weight infants. DESIGN, SETTING, AND PATIENTS This study was a randomized, blinded, placebo-controlled trial of fluconazole in premature infants. Infants weighing less than 750 g at birth (N = 361) from 32 neonatal intensive care units (NICUs) in the United States were randomly assigned to receive either fluconazole or placebo twice weekly for 42 days. Surviving infants were evaluated at 18 to 22 months corrected age for neurodevelopmental outcomes. The study was conducted between November 2008 and February 2013. INTERVENTIONS Fluconazole (6 mg/kg of body weight) or placebo. MAIN OUTCOMES AND MEASURES The primary end point was a composite of death or definite or probable invasive candidiasis prior to study day 49 (1 week after completion of study drug). Secondary and safety outcomes included invasive candidiasis, liver function, bacterial infection, length of stay, intracranial hemorrhage, periventricular leukomalacia, chronic lung disease, patent ductus arteriosus requiring surgery, retinopathy of prematurity requiring surgery, necrotizing enterocolitis, spontaneous intestinal perforation, and neurodevelopmental outcomes—defined as a Bayley-III cognition composite score of less than 70, blindness, deafness, or cerebral palsy at 18–22-months corrected age. RESULTS Among infants receiving fluconazole, the composite primary end point of death or invasive candidiasis was 16% (95% CI, 11%–22%) vs 21% in the placebo group (95% CI, 15%–28%; odds ratio 0.73 [95% CI 0.43–1.23]; P=.24; treatment difference −5% [95% CI, −13%–3%]). Invasive candidiasis occurred less frequently in the fluconazole group (3% [95% CI, 1%

    In general, steroid is mainly used as anti-inflammatory action in case of allergic diseases. As one of the side effects of inhalation steroid, a report is given below regarding buccal capsule/esophageal candidiasis. The patient came to the hospital with the chief complaint regarding passage dysphagia in the time of deglutition; pharyngitis and esophageal candidiasis were found by endoscopy of upper gastrointestinal tract.The interview after the endoscopy revealed that the patient, a 69-year-old female was diagnosed as chronic perennial allergic rhinitis a few years ago, and had been inhaling rhinenchysis Beclometasone dipropionate (BDP) before sleep every day for the past two years because using this collunarium seemed to mitigate the nasal obstruction and mucus during sleep. The patient did not report this fact before the endocsopy because she did not associate it with her subjective symptom. In this case, it was assumed that nebulized rhinenchysis BDP was accidentally swallowed to the pharynx and esophagus during sleep. As a treatment, rhinenchysis BDP was canceled and instead Azunol mouth washing (gargling/nasal douche) was used. No antifungal agent was used. In two weeks, the patient reported some improvement, and this was confirmed by reexamination of the upper gastrointestinal tract using endoscope in one month and a half. Pharyngitis was improved, and in the digital endoscopic assessment of esophageal candidiasis complicating inhaled steroid therapy the esophageal candidiasis became Grade I (mild grade). As for the later progress, the patient did not report any subjective symptoms such as nasal obstruction and dysphagia. In addition, the inflammation caused by candidiasis and found in the early examination was improved. The patient in this case was under treatment for thrombosis in the vein of lower extremity, but no complications such as diabetes mellitus or immune deficiency syndrome were observed.

    IL-17 antagonists are effective for psoriasis in clinical trials, but long-term safety is not fully characterized. Since chronic mucocutaneous candidiasis (CMC) is caused by defects in the IL-17 pathway, CMC risk data have been touted as providing reassurance about the safety of IL-17 antagonism. We performed a literature review to identify patients with CMC and compared the prevalence of cancer in these patients to the reported 5-year prevalence. There was a higher prevalence of oropharyngeal (2.5% vs. 0.028%; p esophageal cancer (1.9% vs. 0.013%; p candidiasis in patients taking these medications.

    Full Text Available Aim - to determine population levels of main microbiota and yeast-like fungi of the genus Candida in healthy women and in women with vulvovaginal candidiasis. Materials and methods. For 10 years we have been surveyed 270 women in reproductive age from 19 to 34 years old with vulvovaginal candidiasis and 73 healthy women. In all patients population level of main microflora and yeast-like fungi of the genus Candida in vulvovaginal content has been determined. The isolation of yeast-like fungi of the genus Candida has been performed by seeding of vulvovaginal content on a solid Saboaraud nutrient medium and on Saboaraud medium with the addition of cycloheximide, relatively with pure culture. "Seedlings test" and identification by species with establishment of population level had been performed in each individual case. Results. Coexistence of representatives of the ecosystem "microorganism - microbiota" and compared the changes of microecology of vulvovaginal content in healthy women and women with vulvovaginal candidiasis were defined. In the study of population level of yeast-like fungi of the genus Candida in vulvovaginal content in women with vulvovaginal candidiasis it was found that the dominant species was C. albicans, of population level of which were different from other species, such as C. guillіermondii by 1.77 %, C. krusei - by 4.82 %, C. glabrata - by 5.78 %, C. kefyr – by 8.19 %, C. tropicalis – by 8,35 %, C. inconspicua and C. zeylanoides by 15.08 %. Thus, in the vulvovaginal content of women with vulvovaginal candidiasis yeast-like fungi of the genus Candida of 8 different taxons were at the population level over 5,00 lg CFU/ml, which can not only persist but they were suspected to be agents of inflammation. The results of the study of population levels of autochtonous obligate and facultative bacteria of vulvovaginal content of women with vulvovaginal candidiasis indicated that the level of Lactobacteria decreased by 67

    Full Text Available Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED is a rare disorder caused by mutations in the autoimmune regulator (AIRE gene, leading to defects in T cell selection. The disease manifestations include both autoimmune tissue destruction and immunodeficiency, with specific susceptibility to chronic mucocutaneous candidiasis. Studies have demonstrated a wide repertoire of high affinity tissue- and cytokine-specific antibodies in patients with APECED. Here, we review the antigenic targets and function of these disease-causing and disease-ameliorating antibodies.

    Full Text Available No último século, numerosos avanços em pesquisas e tecnologias biomédicas na área odontológica foram responsáveis por melhorias na saúde e no bem-estar das populações(1. Entretanto, apesar das grandes realizações no âmbito da saúde bucal, muitos problemas ainda permanecem, como a cárie dental, a mais comum das doenças bucais. A prevalência da cárie dentária apresentou uma tendência de declínio nas três últimas décadas do século XX e no início do século XXI, especialmente nos países desenvolvidos, contudo, ainda é considerada uma importante questão de saúde pública mundial, afetando de 60% a 90% das crianças em idade escolar, além da vasta maioria dos adultos(2-4. No levantamento epidemiológico SB Brasil 2010(5, foram observadas melhoras na condição bucal dos brasileiros, porém, ainda é alta a prevalência de cárie. Entre os adolescentes de 15 a 19 anos, por exemplo, a média de dentes afetados foi de 4,25 mais que o dobro do número médio encontrado aos 12 anos. Entre os idosos de 65a 74 anos, o número de dentes cariados, perdidos e obturados (CPO praticamente não se alterou, ficando em 27,5 em 2010, enquanto, em 2003, a média era de 27,8.

Material y métodos: La investigación realizada fue de tipo clínico, prospectivo y longitudinal en un total de 45 pacientes de ambos sexos cuyas edades oscilaron entre 21 y 35 años de edad. Los pacientes fueron asignados aleatoriamente en tres grupos; el primero que recibió colutorios de cloruro de cetilpiridinio, el segundo que recibió colutorios de triclosán y el tercero que fue consignado como grupo-control (colutorios con agua. Previo al uso del enjuague bucal se realizó una encuesta a la totalidad de pacientes con respecto a los hábitos básicos de higiene bucal y un odontograma en el que se determinó el riesgo de caries de los sujetos incluidos en el estudio. Así mismo se realizó un recuento de colonias de streptococos orales en una muestra de saliva inicial de cada paciente. Después del uso del colutorio respectivo se realizó un nuevo recuento de colonias de streptococos, cuyos resultados fueron contrastados con la muestra inicial. Los resultados mostraron que el uso de triclosán o cloruro de cetilpiridinio reducen significativamente el recuento de colonias de streptococos orales. La reducción media en el recuento de streptococos fue 146,200 UFC/ml en los pacientes que usaron triclosán y 113,670 UFC/ml en los pacientes que utilizaron cloruro de cetilpiridinio. Además, se halló una asociación significativa entre el tipo de saliva, el número de superficies de caries y el recuento inicial de colonias de streptococos. (p<0.05. Conclusiones: Se concluyó en la verificación experimental acerca de la mayor eficacia que presentó el colutorio de triclosán frente al colutorio de cloruro de cetilpiridinio.

    To identify clinical spectrum, management and outcome of neonatal candidiasis. The retrospective study was conducted at the Shifa International Hospital, Islamabad, Pakistan, and comprised microbiological records of all the babies admitted to the Neonatal Intensive Care Unit from January 2009 to January 2014 that were reviewed to identify those with positive candida cultures. Medical records were analysed for demographic and clinical spectrum features, management and outcome. SPSS 16 was used statistical analysis. Of the total 1550 neonatal admissions, 560 (36%) had positive cultures, and, of them, candida was isolated in 49(8.8%) neonates. Among them, 13(26%) had candida albicans and the rest had candida species. Majority were males 34(70%), and preterm with 30(61%) being <37 weeks. The mean birth weight was 2000±873 grams. Mean age at admission was 6±7.6 days. Overall, 39(80%) had ≥2 risk factors. The commonest site of isolation was blood in 41(84%). Besides, 32 (65%) received fluconazole alone for treatment. Mean duration of anti-fungal therapy was 10±5 days (range: 1-21 days). Twelve (24%) neonates expired and the cause of death was candida sepsis in 10(20%) cases. Mortality was not significantly associated with gender, place of birth, gestation, risk factors, length of stay, prior antibiotic exposure or receipt of antifungal prophylaxis except those who were ≤1500 grams (p<0.05). Approximately one in ten at-risk neonates may develop candida sepsis with high mortality. Early institution of anti-fungal therapy may prove to be life-saving.

    Oral candidiasis (OC) is a potential oral complication in Sjögren's syndrome (SS). Some studies indicate that the low stimulated salivary flow and not low unstimulated salivary flow is associated with OC in SS, while others report that the underlying autoimmune disorders contribute to OC, based solely on correlation coefficients. Given the conflicting and limited existing evidence, we purposed to ascertain the role of both salivary gland dysfunction (hyposalivation based on unstimulated and stimulated flow rates) and autoimmunity (SS, other autoimmune disorders) in OC among those with SS, other salivary gland dysfunction, and non-salivary gland dysfunction controls (NSGD). A nested case-control study was designed within a larger NIH/NIDCR cohort. Descriptive analyses, nonparametric tests, comparative analyses, and multivariate logistic regression analyses were undertaken. Data on 1526 subjects (701 SS, 247 ISS, 355 Sicca, and 223 NSGD) were obtained from the source cohort of 2046 and analyzed for this study. The median whole unstimulated salivary flow rate (WUS, ml 15 min -1 ) was lower in SS (0.8, interquartile range (IQR) 1.8) compared to ISS (5.5, IQR: 5.2, P hyposalivation [WUS (OR = 5.1, 95%CI: 2.5-10.4, P hyposalivation with WUS being a stronger predictor than TSS) and autoimmunity (SS, other autoimmune disorders, medications, i.e., DMARDS) are both independent predictors of OC. Diabetes mellitus is an independent predictor of OC among those with salivary gland dysfunction. Our findings suggest that these independent predictors should be considered in the prevention and management of OC in this population. © Published 2016.

    Noonan syndrome is a genetic disorder with variable expression of distinctive facial features, webbed neck, chest deformity, short stature, cryptorchidism and congenital heart disease. The association of Noonan syndrome and giant cell granulomas of the mandible is widely reported. However, Noonan syndrome may also be associated with single or multifocal tenosynovial giant cell tumors, also referred to as pigmented villonodular synovitis. We report a child with Noonan syndrome, giant cell granulomas of the mandible and synovial and tenosynovial giant cell tumors involving multiple joints and tendon sheaths who was initially misdiagnosed with juvenile idiopathic arthritis. It is important for radiologists to be aware of the association of Noonan syndrome and multifocal giant cell lesions, which can range from the more commonly described giant cell granulomas of the mandible to isolated or multifocal intra- or extra-articular tenosynovial giant cell tumors or a combination of all of these lesions.

A abordagem das políticas de saúde procedeu-se sob teoria de M. Foucault na obra Arqueologia do Saber. Utilizou-se de revisão de documentos normativos do SUS e de publicações do período de 2000 a 2012. Procurou-se desvelar, a partir da organização tecnológica (categoria de análise como tais políticas abordam as necessidades de saúde da população e quais ferramentas, instrumentos e tecnologias são oferecidas para o cuidado em saúde bucal.

O levantamento de artigos sobre a atual PNSB destacou nos serviços um modus operandi calcado na pragmática prática odontológica, plena de conflitos e contradições. Para que as diretrizes da PNSB transformem a prática em saúde bucal com novos arranjos tecnológicos no processo de trabalho, outras formas de vínculo e comprometimento devem ser almejadas. É necessário repensar a tecnologia do cuidado em saúde bucal como possibilidade da atenção com integralidade e de sua legitimação como um dos componentes da saúde em uma expressão ampliada: a da qualidade de vida.

    To evaluate the power profile within the optic zone of different designs of multifocal contact lenses (CLs) and to analyze how the effect of pupil size could impact on their optical performance. The optical power distribution within the optic zones of multifocal CLs was measured by the Nimo TR1504 (LAMBDA-X, Belgium). The multifocal CLs under study were the Acuvue Bifocal, the Acuvue Oasys for Presbyopia, the PureVision Multifocal and the PureVision 2 for Presbyopia. Each design was considered in all their available addition powers. All lenses had a nominal power of -3.0D. At the same time, three lenses of each model were considered and five consecutive readings of each lens were performed. The results show that the PureVision Multifocal and the PureVision 2 for Presbyopia have aspheric power profiles. Both designs showed aspheric center-near designs with a smoother progression of the optical power in the PureVision 2 for Presbyopia. The Acuvue Bifocal and the Acuvue Oasys for Presbyopia are shown to have concentric alternating near and far zones. Apart from the refractive rings, the Acuvue Oasys for Presbyopia showed an increase in negative (or less positive) values toward the periphery of the lens. Besides the refraction, the knowledge of the power profiles of multifocal CLs and the effect of pupil size on the optical distribution of these lenses could be crucial to understand the performance of these designs when they are fitted.

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

    Spatial-light-modulators (SLM) are increasingly used as active elements in adaptive optics (AO) systems to simulate optical corrections, in particular multifocal presbyopic corrections. In this study, we compared vision with lathe-manufactured multi-zone (2-4) multifocal, angularly and radially, segmented surfaces and through the same corrections simulated with a SLM in a custom-developed two-active-element AO visual simulator. We found that perceived visual quality measured through real manufactured surfaces and SLM-simulated phase maps corresponded highly. Optical simulations predicted differences in perceived visual quality across different designs at Far distance, but showed some discrepancies at intermediate and near.

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

    Full Text Available O aumento da intensidade da quimioterapia e radioterapia no tratamento do câncer tem elevado a incidência de efeitos colaterais, em especial da mucosite bucal. OBJETIVO E MÉTODO: Através de revisão bibliográfica realizou-se atualizar informações quanto à definição, características clínicas, incidência, etiologia, patofisiologia, morbidade associada, prevenção e tratamento dessa manifestação clínica. RESULTADOS: Estudos atuais definem a mucosite bucal como uma inflamação e ulceração dolorosa bastante freqüente na mucosa bucal apresentando formação de pseudomembrana. Sua incidência e severidade são influenciadas por variáveis associadas ao paciente e ao tratamento a que ele é submetido. A mucosite é conseqüência de dois mecanismos maiores: toxicidade direta da terapêutica utilizada sobre a mucosa e mielossupressão gerada pelo tratamento. Sua patofisiologia é composta por quatro fases interdependentes: fase inflamatória/vascular, fase epitelial, fase ulcerativa/bacteriológica e fase de reparação. É considerada fonte potencial de infecções com risco de morte, sendo a principal causa de interrupção de tratamentos antineoplásicos. Algumas intervenções mostraram-se potencialmente efetivas para sua prevenção e tratamento. Entretanto, faz-se necessária a realização de novos estudos clínicos mais bem conduzidos para obtenção de melhor evidência científica acerca do agente terapêutico de escolha para o controle da mucosite bucal, permitindo a realização da quimioterapia e radioterapia do câncer em parâmetros ideais.Tincreasing the intensity of radiation therapy and chemotherapy in the management of cancer has increased the incidence of adverse effects, especially oral mucositis.

  16. [Halos and multifocal intraocular lenses: origin and interpretation].

    To present the theoretical and experimental characterization of the halo in multifocal intraocular lenses (MIOL). The origin of the halo in a MIOL is the overlaying of 2 or more images. Using geometrical optics, it can be demonstrated that the diameter of each halo depends on the addition of the lens (ΔP), the base power (P(d)), and the diameter of the IOL that contributes to the «non-focused» focus. In the image plane that corresponds to the distance focus, the halo diameter (δH(d)) is given by: δH(d)=d(pn) ΔP/P(d), where d(pn) is the diameter of the IOL that contributes to the near focus. Analogously, in the near image plane the halo diameter (δH(n)) is: δH(n)=d(pd) ΔP/P(d), where d(pd) is the diameter of the IOL that contributes to the distance focus. Patients perceive halos when they see bright objects over a relatively dark background. In vitro, the halo can be characterized by analyzing the intensity profile of the image of a pinhole that is focused by each of the foci of a MIOL. A comparison has been made between the halos induced by different MIOL of the same base power (20D) in an optical bench. As predicted by theory, the larger the addition of the MIOL, the larger the halo diameter. For large pupils and with MIOL with similar aspheric designs and addition (SN6AD3 vs ZMA00), the apodized MIOL has a smaller halo diameter than a non-apodized one in distance vision, while in near vision the size is very similar, but the relative intensity is higher in the apodized MIOL. When comparing lenses with the same diffractive design, but with different spherical-aspheric base design (SN60D3 vs SN6AD3), the halo in distance vision of the spherical MIOL is larger, while in near vision the spherical IOL induces a smaller halo, but with higher intensity due to the spherical aberration of the distance focus in the near image. In the case of a trifocal-diffractive IOL (AT LISA 839MP) the most noticeable characteristic is the double-halo formation due to the 2 non

    Multifocal breast cancer (MFBC), defined as multiple synchronous unilateral lesions of invasive breast cancer, is relatively frequent and has been associated with more aggressive features than unifocal cancer. Here, we aimed to investigate the genomic heterogeneity between MFBC lesions sharing similar histopathological parameters. Characterization of different lesions from 36 patients with ductal MFBC involved the identification of non-silent coding mutations in 360 protein-coding genes (171 tumour and 36 matched normal samples). We selected only patients with lesions presenting the same grade, ER, and HER2 status. Mutations were classified as 'oncogenic' in the case of recurrent substitutions reported in COSMIC or truncating mutations affecting tumour suppressor genes. All mutations identified in a given patient were further interrogated in all samples from that patient through deep resequencing using an orthogonal platform. Whole-genome rearrangement screen was further conducted in 8/36 patients. Twenty-four patients (67%) had substitutions/indels shared by all their lesions, of which 11 carried the same mutations in all lesions, and 13 had lesions with both common and private mutations. Three-quarters of those 24 patients shared oncogenic variants. The remaining 12 patients (33%) did not share any substitution/indels, with inter-lesion heterogeneity observed for oncogenic mutation(s) in genes such as PIK3CA, TP53, GATA3, and PTEN. Genomically heterogeneous lesions tended to be further apart in the mammary gland than homogeneous lesions. Genome-wide analyses of a limited number of patients identified a common somatic background in all studied MFBCs, including those with no mutation in common between the lesions. To conclude, as the number of molecular targeted therapies increases and trials driven by genomic screening are ongoing, our findings highlight the presence of genomic inter-lesion heterogeneity in one-third, despite similar pathological features.

    Full Text Available El carcinoma escamocelular es la neoplasia maligna más común en la cavidad bucal. Los sitios anatómicos más frecuentemente afectados son el labio inferior, los bordes laterales de lengua y el suelo de la boca. Su etiología es multifactorial, aunque está íntimamente relacionada con factores ambientales como el tabaquismo y el alcoholismo. El cuadro clínico se caracteriza generalmente por la presencia de placas blancas, placas eritematosas, placas entre eritematosas y blancas, úlceras de bordes levantados y masas exofíticas. El tratamiento consiste en la extirpación quirúrgica, la radioterapia, quimioterapia o ambos tratamientos. Este artículo presenta un caso de carcinoma escamocelular bucal en un paciente del sexo masculino, de 70 años de edad. En el mismo se describen los hallazgos clínicos, histopatológicos y el tratamiento correspondiente del caso. El diagnóstico precoz y correcto posibilitó la cura en este caso.The squamocellular carcinoma is a malignant neoplasm commonest in the buccal cavity. The more frequently involved anatomical sites are the lower lip, the tongue's lateral edges and the mouth floor. Its etiology is multifactor although it is closely related to smoking and alcoholism. Clinical picture is generally characterized by the presence of different types of white, erythematous, between erythematous and white plaques, ulcers with raised edges and exophytic masses. Treatment includes surgical removal, radiotherapy, chemotherapy or both. In present paper the case of a man aged 70 presenting with buccal squamous carcinoma describing the clinical, and the histopathologic findings and its corresponding treatment. The early and appropriate diagnosis allowed the cure of this case.

    Full Text Available Com o objetivo de analisar os estudos epidemiológicos sobre a saúde bucal dos idosos no Brasil, foram pesquisados todos os artigos indexados nas bases de dados BBO, LILACS e MEDLINE, a partir de 1988, data da publicação do Levantamento Epidemiológico Nacional. Foram encontrados 29 artigos, dos quais sete estudos foram analisados quanto à metodologia utilizada (faixa etária, tipo de amostra, forma de apresentação dos dados e quanto aos resultados apresentados (índice CPOD, participação de dentes extraídos, percentual de edêntulos, e uso e necessidade de prótese. O CPOD encontrado variou de 26,8 a 31,0, sendo que o componente extraído representou cerca de 84% desse índice. A prevalência do edentulismo ficou em 68%. Somente 3,9%, um pequeno percentual dos idosos, não necessitam nem usam qualquer tipo de prótese, e o uso da prótese total é mais freqüente no arco superior do que no inferior. A falta de padronização na organização e apresentação dos dados, assim como a sua escassez, prejudicaram a análise, sugerindo que deva haver uma maior preocupação por parte dos pesquisadores quanto à realização de novas pesquisas, e principalmente, quanto à maneira como estas serão conduzidas. Apesar disso, confirmaram-se as condições muito precárias de saúde bucal em idosos no Brasil.
