Hand, Foot, and Mouth Syndrome in an Immunocompetent Adult: a Case Report

BACKGROUND: Hand, foot, and mouth syndrome (HFMS) is a common acute illness. It is characterized by mild clinical symptoms including fever, blisters, and sores in the mouth and on the palms and soles following a 3- to 7-day incubation period. This syndrome is rarely seen in adults. CASE PRESENTATION: A 35-year-old male Caucasian patient had a history of multiple episodes of acute pharyngitis, hypertension, hypercholesterolemia, and occasional abdominal pain. He presented with polyarthralgia in the knees and hands and odynophagia, followed by fever, oral mucosal aphthous lesions, and vesicles on the palms and soles. Three weeks after presentation, he was admitted to the emergency room with acute myocarditis. The in-hospital evaluation revealed positive serology for coxsackie A9 (1:160), positive anti-transglutaminase and anti-gliadin antibodies, normal immunoglobulins, and human immunodeficiency virus negativity. CONCLUSION: We herein describe a case of HFMS that was associated with coxsackie A9 infection complicated by acute myocarditis. Although an association between celiac disease and HFMS has not been described, this patient's immunologic disruption could have favored the development of infection and ultimately HFMS.

Doença de Mãos-Pés-Boca no Adulto - Um Caso Clínico

A doença de mãos-pés-boca é uma infecção viral, mais frequentemente causada pelos vírus coxsackie A16 e enterovírus 71, que afecta preferencialmente crianças com idade inferior a 10 anos. Geralmente é uma doença benigna, caracterizada por febre e vesículas na boca e extremidades distais, mas também pode associar-se a complicações mais graves com meningoencefalite ou miocardite. Os autores reportam um caso de DMPB num adulto imunocompetente, com 27 anos de idade, que apresentava pápulas das mãos, pés e cavidade oral, algumas com progressão posterior para vesículas. A exuberância do quadro clínico e curso mais prolongado da doença também constituíram características pouco usuais.

Hand Involvement in Ollier Disease and Maffucci Syndrome: a Case Series

Ollier Disease and Maffucci Syndrome are two rare diseases that can cause tumors in several organs, having a special predilection for the hand. However, there have been very few reports in the literature focusing on hand manifestations of these diseases. We report the cases of three female patients: one with Ollier Disease, and two other with Maffucci Syndrome. All patients had hand involvement as their initial primary complaint. The Ollier Disease patient developed chondrosarcomas of two digits and had to have these fingers amputated. One of the Maffucci patients died one year after presentation from a brain glioblastoma. These cases emphasize the importance of early diagnosis of Ollier Disease and Maffucci Syndrome, as these two conditions are associated not only to crippling hand deformity, but also to a significant risk of chondrosarcoma, and other malignant tumors.

Diabetes Mellitus and Renal Disease: When to Perform a Renal Biopsy?

Background: Several studies suggest that nondiabetic renal disease (NDRD) is common in patients with diabetes mellitus. The aim of this analysis of renal biopsies in diabetic patients was (a) to assess the prevalence and type of NDRD and (b) to identify its clinical and laboratory predictors. Methods: This retrospective study analysed clinical and laboratory data and biopsy findings in diabetic patients observed by a single pathologist over the past 25 years. Based on biopsy findings, patients were categorised as (i) isolated diabetic nephropathy,(ii) isolated NDRD and (iii) NDRD superimposed on diabetic nephropathy. Results: Of the 236 patients studied, 60% were male and the mean age was 56.3 (±14.2) years. Of these, 91% had known diabetes mellitus at the time of biopsy (13% type 1 and 87% type 2). Isolated diabetic nephropathy was found in 125 (53%), isolated NDRD in 89 (38%) and NDRD superimposed on diabetic nephropathy in 22 (9%) patients. The main indication for biopsy in the three groups was nephrotic proteinuria. Patients with isolated NDRD and NDRD superimposed on diabetic nephropathy presented acute deterioration of renal function more frequently (p<0.001) and had more microhaematuria(p<0.001) as indications for renal biopsy. Focal segmental glomerulosclerosis and membranous nephropathy were the most frequent diagnoses in patients with NDRD. Patients with isolated diabetic nephropathy were younger (p=0.02), presented a longer duration of diabetes mellitus (p<0.001) and had more frequent retinopathy (p<0.001). The prevalence of microhaematuria was higher in patients with isolated or superimposed NDRD (p=0.01). Conclusion: The prevalence of NDRD (either isolated or superimposed on diabetes mellitus) is remarkably frequent in diabetic patients in whom nephrologists consider renal biopsy an appropriate measure. Predictors of NDRD were older age, shorter duration of diabetes mellitus, absence of retinopathy and presence of microhaematuria.

Mineral and Bone Disease (MBD) on a Kidney Transplant Patient

A 50-year-old post-menopausal recipient of a kidney allograft with bone pain, osteoporosis, persistent hypercalcaemia and elevated parathormone (PTH) levels, despite a satisfactory graft function, was treated with bisphosphonates and cinacalcet starting, respectively, 5 and 6 months after renal transplantation (RT). Sixteen months after treatment, there was improvement of bone mineral density (BMD) measured by dualenergy X-ray absorptiometry (DEXA). A bone biopsy was taken, unveiling a surprising and worrisome result. Post-RT bone disease is different from classic CKD-MBD and should be managed distinctly, including, in some difficult cases, an invasive evaluation through the performance of a bone biopsy, as suggested in the KDIGO guidelines.

Diabetic Foot Infections: Current Diagnosis and Treatment

Diabetes mellitus (DM) is a global epidemic, and diabetic foot ulcer (DFU) is one of its most serious and costly complications. DFUs result from a complex interaction of a number of risk factors. Once the protective layer of skin is broken, deep tissues are exposed to bacterial infection that progresses rapidly. Patients with DFUs frequently require amputations of the lower limbs and, in more than half the cases, infection is the preponderant factor. Given the challenges of treating these complex infections, this paper aims to provide a hospital-based framework for the diagnosis and treatment of diabetic foot infections (DFIs). We propose a treatment-oriented assessment of DFIs based on a cross-examination of the medical, foot, and wound history; a systemized and detailed physical examination; and the results of complementary diagnostic procedures. We stress the need for a clinical diagnosis of DFIs and the importance of microbiological evaluation for antibiotic therapy guidance. Regarding treatment, we propose a multidisciplinary approach prioritizing invasive infection drainage, necrosis debridement, and the prompt start of empirical antibiotic therapy, followed by complete and appropriate vascular reconstruction. For severe DFIs, we suggest that negative pressure wound therapy (NPWT) be included in the treatment pathway. We also provide rules for managing particular situations, such as osteomyelitis. It is our hope that this protocol will improve the hospital management of DFIs and, ultimately, the prognosis of DFI patients.

Adolescents and School Asthma Knowledge and Attitudes

Introduction: bronchial asthma is a chronic disease that affects a high percentage of adolescents, with a significant restriction of daily activities, and is a cause of school absenteeism. The relationships between adolescents and asthma disease in school were assessed, with a view to improving knowledge about the asthmatic adolescent. Methods: a survey was conducted in the Lisbon metropolitan area, covering urban (Lisbon) and rural (Lourinh˜a ) zones and including 1879 students and 81 teachers from the 7th to 9th high school years. The study groups were asthmatic students, their peers, and teachers. A self-administered questionnaire was applied to collect information. The results were compared with a reference group of 91 asthmatic students attending our Department of Immunoallergy-Hospital Dona Estefânia. Cotinine urinary measurements were made in a sample of asthmatics and a control group. Results: the prevalence of current asthma among students was 10%. Estimates of asthma annual burden among 7th to 9th year students from Lisbon and Lourinh˜a high schools included 4,307 days missed from school, 4,148 medical consultations and a minimum of 351 hospital emergency care and 80 hospital admissions. Exposure to passive smoking was not significantly different between asthmatic students and theirs peers. Cotinine urinary measurements did not discriminate between exposed and non-exposed individuals. Cigarette smoking was almost as common among adolescent asthmatics (5.4%) as it was in non-asthmatic subjects (6.7%). However, 55% of asthmatics mentioned active and passive smoking as an asthma exacerbating factor. Asthmatic students, theirs peers and teachers showed a deficient knowledge about asthma (mean group scores: 17.6; 14.2 and 17.7 of a possible 30), particularly in the areas related to asthma recognition and its management. Asthmatics attending our Allergy Department had the highest scores. All groups showed tolerance in the sense of a positive and understanding attitude toward a person with asthma. However, traditional beliefs about asthma disease (dependence, inferiority...) were confirmed. A positive correlation between knowledge levels and tolerance attitudes was found. Conclusion: in view of the dimension of the asthma problem in adolescence and its social and economic impact, it is justifiable to assess the need for the implementation of asthma education programs in schools in order to improve asthma management by the adolescents and their schools.

Reconstruction of Large Defect of Foot with Extensive Bone Loss Exclusively Using a Latissimus Dorsi Muscle Free Flap: a Potential New Indication for this Flap

In cases of extensive damage to the foot, with significant bone loss, it is generally accepted that reconstruction must include bone flaps or grafts either in the emergency setting or subsequently. In this report, we describe the case of an 18-year-old student with an avulsion injury of the dorsum of his right foot. Consequently, he lost most of the soft tissue over the dorsum of the foot and the cuboid, navicular, and cuneiform bones. A latissimus dorsi free flap was used to reconstruct the defect. A functional pseudoarthrosis developed between the remaining bones of the foot, and the patient experienced satisfactory foot function after rehabilitation. For this reason, no additional reconstructive procedure was undertaken. This case suggests that it might be adequate to use the latissimus dorsi muscle flap more liberally than previously reported in the reconstruction of extensive defects of the dorsum of the foot, including cases with significant bone loss. This option could avoid the morbidity and inconvenience of a second surgery and the need to harvest a bone flap or graft.

Lupus and Pregnancy. 15 Years of Experience in a Tertiary Center

This retrospective study was designed to evaluate the outcome of pregnancies in women diagnosed with systemic lupus erythematosus (SLE) followed in a tertiary fetal–maternal center. Data were collected from clinical charts between January 1993 and December 2007, with a total of 136 pregnancies (107 patients). Mean maternal age was 29 years, with the vast majority of patients being Caucasian. Most patients were in remission 6 months prior to pregnancy (93%) and the most frequently affected organs were the skin and joints. Renal lupus accounted for 14% of all cases. Twenty-nine percent of patients were positive for at least one antiphospholid antibody (aPL) and nearly 50% had positive SSa/SSb antibodies. All patients with positive aPL received low-dosage aspirin and low molecular- weight heparin (LMWH). There were no pregnancy complications in more than 50% of cases and hypertensive disease and intrauterine growth restriction were the most common adverse events. There were 125 live births, one neonatal death, eight miscarriages, and three medical terminations of pregnancy. Preterm delivery occurred in 25% of pregnancies. Our results are probably the conjoined result of a multidisciplinary approach together with a systematic management of SLE pregnancies, with most patients keeping their prior SLE medication combined with low-dosage aspirin and LMWH in the presence of aPL.

Collapsing Glomerulopathy. A Treatable Disease?

Renal disease is a relatively common complication in human immunodeficiency virus (HIV) infected patients and has become the fourth leading cause of death in AIDS individuals, immediately following septicaemia, pneumonia and hepatic disease. HIV associated nephropathy, HIV associated immune complex renal disease and HIV associated thrombotic microangiopathy are the main causes of chronic renal failure in this population. The authors report a case of a 44 year-old black male, HIV 1 infected with low CD4 count, admitted to the nephrology department with non nephrotic proteinuria and renal failure. Renal biopsy revealed a focal segmental glomerulosclerosis collapsing variant. The patient was treated with highly active antiretroviral therapy and an ACE inhibitor and, at 3 months of follow-up, has recovered his renal function. This case illustrates the efficacy of highly active antiretroviral therapy (HAART) on HIV associated nephropathy. Prospective studies are needed to evaluate HAART in the treatment of HIV associated nephropathies.
