Bone Marrow Involvement in a Patient with Paracoccidioidomycosis: A Rare Presentation of Juvenile Form

Paracoccidioides brasiliensis rarely shows bone marrow involvement and its response to treatment with itraconazole in children needs further assessment. We describe here a child with a juvenile disseminated form of paracoccidioidomycosis, which showed reticuloendothelial system involvement and the presence of Paracoccidioides brasiliensis in the bone marrow. The patient showed an effective and rapid response to itraconazole therapy.

Septic shock caused by Plesiomonas shigelloides in a patient with sickle beta-zero thalassemia

Invasive infection and extraintestinal complications are rarely caused by Plesiomonas shigelloides, a water-borne bacterium belonging to the Vibrionaceae family. We report a case of a 16-year-old female patient with sickle beta-zero thalassemia who survived septic shock caused by P. shigelloides associated with secondary acute respiratory distress syndrome and disseminated intravascular coagulation. Treatment with a carbapenem was successful, and the patient recovered without any sequelae. The previous reports of P. shigelloides sepsis are cited, and possible pathogenic mechanisms are discussed.

Kaposi sarcoma and paracoccidioidomycosis in the same fragment of oral mucosa biopsy: a rare association in human immunodeficiency virus-positive patient. A case report

The immunossuppression caused by HIV infection makes the affected individuals more susceptible to some diseases including infections, neoplasms, or even the association between them. Kaposi sarcoma (KS) is the most common AIDS-related neoplasm, featured as an angioproliferative disorder. Its cause seems to be related to the human herpesvirus type 8 and it is usually associated with lower CD4+ T cell count. Oral involvement is frequent, presenting red to blue-purplish plaques, maculaes, and nodules. On the other hand, paracoccidioidomycosis (PCM) is a systemic mycosis, endemic in Latin America, caused by Paracoccidioides brasiliensis. This mycosis is not commonly related to human immunodeficiency virus (HIV) infection, although PCM can be present in immunosuppression cases. Oral lesions, as granulomatous ulcers, are often identified in seropositive patients with PCM. A rare case, in which a male HIV-positive patient presented simultaneously Kaposi sarcoma and PCM in the same fragment of oral mucosa biopsy, is described. To the best of our knowledge, this concomitant association had not been previously described. (C) 2011 Elsevier Inc. All rights reserved.

Untreated Dental Caries in a Brazilian Paediatric AIDS Patient Population

Purpose: The objective of the present study was to assess the prevalence of untreated caries in a Brazilian paediatric acquired immunodeficiency syndrome (AIDS) patient population and its association with sociodemographic, behavioural and clinical characteristics. Materials and Methods: The study group was comprised of 125 HIV-infected patients (aged 3 to 15 years) who had already manifested AIDS and were assisted in a specialised health care unit. Dental examinations followed the World Health Organization`s guidelines for oral health surveys. Family caregivers provided information about the socioeconomic standing and the behaviour of their children. Patients` medical records in the hospital provided information on the clinical status of patients. A Poisson regression analysis was used for assessing the covariates for the prevalence of untreated dental caries, as adjusted by age. Results: The prevalence of untreated caries was 58%; a higher prevalence was found in younger children with primary and mixed dentition. The prevalence of untreated caries associated significantly with lower socioeconomic status (household crowding and schooling of the caregiver), dietary habits (higher frequency of sugar consumption) and poorer clinical status (HIV viral load and symptom severity). Conclusions: The high burden of untreated caries on paediatric AIDS patients reinforced the importance of integrating the clinician with the interdisciplinary health care team that assisted these children. The identification of socioeconomic and behavioural factors associated with caries experience reinforced the importance of the attention that children with AIDS received within their own households for the prevention of dental disease, particularly a proper nutritional advisement and monitoring of dental hygiene.

Emerging technologies for the prevention of dental caries. Are current methods of prevention sufficient for the high risk patient?

Fluorides and chlorhexidine are technologies that are 65 and 40 years old, respectively. This overview argues that current methods of caries prevention are not effective for the high caries risk patient. In this review examples, arguments and recommendations are provided to address the high caries risk patient that include: failure of comprehensive chemical modalities treatments to address the high caries risk patient; ecological alteration - would this be an effective approach?; and biomaterials and oral microbiome research to address the high caries risk patient.

Monostotic fibrous dysplasia: a 23-year follow-up of a patient with spontaneous bone remodeling

Fibrous dysplasia is a benign fibro-osseous disease that affects one or more bones. Although its etiology has been defined, the mechanism of spontaneous resolution is still unclear. There is strong evidence indicating the occurrence of stabilization when bone maturation is completed. Deformities that lead to esthetic and functional disorders are observed in almost all cases. Plastic surgery is often recommended when the maxilla and mandible are involved. In the case of mild deformities, careful follow-up during skeletal growth is recommended. We describe here the 23-year follow-up of a patient with monostotic fibrous dysplasia whose disease had stabilized by 13 years of follow-up.

Odontogenic keratocyst and multiple supernumerary teeth in a patient with Ehlers-Danlos syndrome - A case report and review of the literature

Ehlers-Danlos syndrome (EDS) is a hereditary disorder of the connective tissue related to collagen metabolism. Deficiency or alteration of the collagen present in the tissues results in some classic signs such as skin hyperelasticity, articular hypermobility, and vascular fragility, among others. In addition, EDS oral manifestations are rarely cited in the literature. The aim of this article is to report a rare case of a young female patient with EDS who presented supernumerary teeth and an odontogenic keratocyst. There is no report in the literature of the simultaneous occurrence of these alterations. The article further highlights the importance of EDS diagnosis in patients who need dental treatment and the due care for their assistance.

Conceptualizing quality of life for elderly people with stroke

Purpose : Despite increased interest in quality of life (QOL) as an outcome measure and as a means of identifying client needs in health care, its conceptualisation and the identification of its constituents have been poorly researched for elderly people with stroke in Hong Kong. Method: This article analysed the literature to identify components relevant to the QOL of Chinese elderly people with stroke living in the community in Hong Kong. Results : While common components of QOL for elderly people with and without stroke and regardless of cultural background were identified, a number were specific to an elderly Chinese stroke population. Conclusion : Recommendations for future research have been made with reference to further exploring and validating these components for the target population. A clear understanding of these aspects is essential for the development of sensitive QOL measures to guide and evaluate service delivery to this population.

Hemiplegic shoulder pain: defining the problem and its management

Purpose: Hemiplegic shoulder pain can affect up to 70% of stroke patients and can have an adverse impact on rehabilitation outcomes. This article aims to review the literature on the suggested causes of hemiplegic shoulder pain and the therapeutic techniques that can be used to prevent or treat it. On the basis of this review, the components of an optimal management programme for hemiplegic shoulder pain are explored. Method: English language articles in the CINAHL and MEDLINE databases between 1990 and 2000 were reviewed. These were supplemented by citation tracking and manual searches. Results: A management programme for hemiplegic shoulder pain could comprise the following components: provision of an external support for the affected upper limb when the patient is seated, careful positioning in bed, daily static positional stretches, motor retraining and strapping of the scapula to maintain postural tone and symmetry. Conclusions: Research is required to evaluate the effectiveness of the components of the proposed management programme for the prevention and treatment of hemiplegic shoulder pain and to determine in what combination they achieve the best outcomes.
