ABSTRACT

BACKGROUND: Microplastics comprise a significant group of emerging environmental contaminants with the capacity to adsorb several contaminants. These, in turn, undergo bioaccumulation and biomagnification processes throughout aquatic trophic chains. METHODS: Glitter, a microplastic powder composed of a combination of polymers, and raw glitter materials were investigated herein concerning metal and metalloid content, bioavailability, and sorption processes by inductively coupled plasma mass spectrometry (ICP-MS). RESULTS: Metal and metalloid concentrations were higher in glitter than in raw glitter materials, but all were below the limits established by the Brazilian National Health Surveillance Agency. Elements present in glitter originate mainly from pigments and, thus, depend on glitter color. The bioavailability of the determined elements concerning human skin was assessed. Low desorbed concentrations in solution indicate that glitter does not represent a health risk through dermal contact concerning metal and metalloid contamination. However, several elements were shown to undergo significant desorption and adsorption processes. CONCLUSION: The findings reported herein indicate seemingly low human health risks from dermal glitter contact but reinforce glitter risks as aquatic environment metal and metalloid transport vectors.

ABSTRACT

INTRODUCTION: Surgical treatment of craniosynostosis in children may generate secondary cranial vault defects by incomplete ossification process. The incidence of cranial defects after craniosynostosis surgery is poorly reported in the literature with a variable incidence of 0.5% to 18.2%. To better understand the impact and management of the cranial defects after craniosynostosis surgery, we selected and reviewed al cranioplasties that met this criterion between 2002 and 2019. PATIENTS AND METHOD: We found 41 patients (28 M and 13 F) operated between January 2002 to January 2019 who underwent cranioplasty for cranial defects secondary to craniosynostosis surgery in the infancy. All patient were at least 5 years old (range 5 to 17 years, median 11). The indication was aesthetic in 28 patients and for headaches, learning difficulties or changes in the cerebral blood flow in 13 patients. The material used in cranioplasty was the poly-methyl-methacrylate (PMMA) in 40 patients and customized porous hydroxyapatite (CPHA) in 1 patient. RESULTS: The mean follow-up period after cranioplasty was of 37 months (range 2 to 125 months, median of 27 months). In the postoperative period there were no mortality nor neurological complications. There were 3 cases (7%) of superficial local postoperative wound infection but with no evidence of long-term infection. The long-term CT scan follow-up showed no material migration, dislocation or fractures. CONCLUSION: Considering the characteristics of the cranial vault after craniosynostosis surgery the treatment by cranioplasty with heterologous materials appears to be feasible thus avoiding donor site morbidity. For selected cases with small defects, our experience shows that the use of PMMA may be a safe alternative for the cranial vault repair in children older than 5 years.

ABSTRACT

BACKGROUND: Peyronie's Disease (PD) is an acquired connective tissue disorder that often leads to penile curvature (PC) and sexual dysfunction. Penile lengthening procedures (PLP) with four-layered porcine small intestinal submucosa graft (Surgisis® ES; Cook) have been widely used in patients with severe PC when erectile function is preserved. However, complications such as erectile dysfunction (ED) may limit treatment satisfaction. OBJECTIVES: Focusing on patients perspective, our study aims to evaluate longterm patient-reported outcomes, satisfaction, and dissatisfaction predictors after PLP. MATERIAL AND METHODS: This prospective study included 32 patients affected by PD with severe PC submitted to PLP with Surgisis® ES between 2011 and 2014. All patients were submitted to a standardized protocol with regular clinical evaluation at 3, 6 and 12 months, and yearly thereafter. After the third year follow-up, IIEF-5, modified EDITS and an additional non-validated questionnaire were completed. RESULTS: Concerning the surgical procedure, the mean tunical defect area (TDA) was 15.9 ± 6.9 cm2 . The mean follow-up time were 49.6 ± 12.7 months and there was a significant increase in stretched penile length (p = 0.01). Postoperative erectile function as assessed by IIEF-5 was positively correlated with overall treatment satisfaction evaluated through EDITS (p = 0.01). TDA was negatively correlated with postoperative IIEF-5 (R = -0.56, p < 0.001). TDA ≥ 14.375 cm2 can predict ED with 76.9% sensibility and 58.3% specificity. Moreover, TDA ≥ 21.875 cm2 can predict clinically significant ED (IIEF-5 score ≤17) with 80% sensibility and 95.2% specificity. Patient-reported longterm complications were 65.6% decreased penile length, 56.5% diminished rigidity and 25% curvature recurrence. CONCLUSION: PLP using a Surgisis® ES is a valuable surgical option for the treatment of PD with severe PC. Although it results in high rates of long-term patient-reported overall satisfaction, possible outcomes such as postoperative ED must be acknowledged. TDA is a strong predictor for postoperative ED and should be considered in clinical practice to classify patients in low- or high-risk for postoperative ED.

ABSTRACT

Resumen INTRODUCCIÓN: En determinadas circunstancias clínicas, la exotropia intermitente básica requiere resolución quirúrgica. Existen dos técnicas para ello: el retroceso bilateral de rectos laterales y el retroceso/resección unilateral. Aunque el retroceso bilateral es la técnica más utilizada, no está claro cuál de estas técnicas tiene mejores resultados. MÉTODOS: Para responder esta pregunta utilizamos Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante búsquedas en múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, reanalizamos los datos de los estudios primarios, realizamos un metanálisis y preparamos una tabla de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES: Identificamos cinco revisiones sistemáticas que en conjunto incluyeron siete estudios primarios, de los cuales tres son ensayos aleatorizados. Concluimos que el retroceso/resección unilateral podría tener un mayor éxito quirúrgico y probablemente disminuiría la tasa de subcorrección/recurrencia, cuando se le compara al retroceso bilateral de rectos laterales.


Abstract INTRODUCTION: Intermittent exotropia requires surgical resolution under some clinical circumstances. The main techniques are bilateral lateral rectus recession and unilateral recess/resection. Although bilateral recession is the most widely used, it is not clear whether it leads to better results. METHODS: To answer this question we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS: We identified five systematic reviews including seven studies overall, of which three were randomized trials. We concluded unilateral recess/resection might achieve greater surgical success and probably decrease the rate of undercorrection/recurrence when compared to bilateral lateral rectus recession.

ABSTRACT

AIMS: To prospectively validate the existing classifications to stratify subjects with diabetes mellitus (DM) by their risk of diabetic foot ulcer (DFU), in high and low risk settings. METHODS: A prospective multicentre cohort study was conducted, including 446 subjects with DM without active DFU followed in the hospital or primary care setting. Demographic, clinical characterization variables, and those included in the classifications were collected at baseline. Subjects were followed for 1year, until DFU or death. RESULTS: In our sample, with a mean age of 65years, 52% were male; 32 developed a DFU, 7 required an amputation and 18 died. Differences were found between participants' characteristics and classifications' accuracy according to the setting. The great majority of the variables were associated with higher DFU risk. Globally, classifications were highly and equally valid, positive predictive values (PV) were inferior to 40%, negative PV superior to 90% and area under the receiver operating characteristic curve superior to 0.75. DISCUSSION: All the existing classifications are valid to be applied in high risk clinical context and have a very high capacity to categorize as low risk those subjects that will not develop a DFU. Further research is needed in the primary care setting.

ABSTRACT

In the pre-experimental period of a clinical trial, an apparently clinically healthy sheep fitted with ruminal and abomasal cannulas showed changes in the reticular contraction pattern visualized in M-mode ultrasonogram. Radiographic examination revealed a blunt metal screw in its reticulum. By the time change in the reticular motility through the ultrasound examination was detected, the animal had still not expressed any behavioral changes. A description of the clinical case, follow-up of the findings and laboratory data, like white blood cell count, serum pepsinogen and fibrinogen concentrations, were presented. The foreign body was removed through the ruminal cannula and reticular contraction tended to normal. An association of the contraction pattern with measured clinical data was possible, leading to the conclusion that use of M-mode ultrasonography has a potential application in similar clinical situations.

ABSTRACT

BACKGROUND: Ecthyma gangrenosum (EG) is an anatomoclinical syndrome commonly associated with Pseudomonas aeruginosa cutaneous infection. Other microorganisms have also been incriminated on occasion, with other viral, fungal and bacterial agents potentially causing EG. In this report, we present an extremely rare case of an EG caused by methicillin-sensitive Staphylococcus aureus (MSSA) infection. This case, highly characteristic of EG both clinically and histologically, calls into question the physiopathological mechanisms of the disease and provides a reminder that it may be caused by a variety of organisms. PATIENTS AND METHODS: A 62-year-old woman, followed for HIV seropositivity at the AIDS stage, developed a painful purpuric skin rash evolving towards necrotic nodules characteristic of ecthyma gangrenosum. Skin biopsy confirmed the diagnosis of EG due to methicillin-sensitive S. aureus (MSSA) infection without toxins or bacteraemia. DISCUSSION: To the best of our knowledge, this is the first case in the literature in which MSSA is reported as the underlying cause of such lesions.

ABSTRACT

Leishmune is the industrialized version of the FML-saponin vaccine which has been shown to develop 92-95% protection in vaccinated dogs and 76-80% vaccine efficacy against field canine visceral leishmaniasis (CVL) in Brazil. Leishmune has been proven to be safe and tolerable and a transmission-blocking vaccine which renders vaccinated dogs non-infectious to sand fly vectors. In the present investigation, 550 healthy seronegative dogs of endemic and epidemic areas of Brazil were monitored for Leishmune-induced immunogenicity during a 2-year trial. Another group of 588 untreated exposed dogs was also studied in parallel. Both groups were seronegative on day 0. The strong immunogenicity induced by Leishmune vaccine was demonstrated by the 98% of FML-seroconversion, increase in absorbencies, the 82.7% DTH positive reactions and increase in skin test size diameters, the average increase in CD8+ total lymphocytes population in blood (27.1%), expected for QS21 saponin-containing vaccine, the sustained proportions of CD4+ T cells, and the average increased proportions of CD21+ B lymphocytes (42.3%). The Leishmune-induced protection against CVL is demonstrated by the results: 98.8% asymptomatic dogs (at the end of first year) and 99% healthy survivors (at the end of the second year) among vaccinated dogs, compared to the 79.4% asymptomatic and 61% survivor dogs (p<0.001) monitored in the untreated exposed cohort. In spite of the low vaccine coverage, it was possible to detect a 66.1% (p<0.005) reduction in Belo Horizonte and an 80.2% (p<0.005) reduction in Araçatuba of the incidence of CVL among vaccinated dogs, when compared to the global incidence of CVL of each town, respectively. Our preliminary results support the potential use of Leishmune to prevent CVL epidemics.

ABSTRACT

The energetic metabolism and its relationship with body weight generated a vivid controversy, since the Rubner's surface law was introduced into biology. Recently, the multifactor theory (Darveau et al) has caused again a revival of this polemic topic. Moreover, the investigations concerning metabolism and body weight include all terrestrial mammals, from the shrew (3 grams) to the elephant (three tons). The corresponding allometric exponent for standard metabolic rate, both theoretical and empirical, fluctuates around an average value of 0.75, in contrast with the surface law, which postulated a value of 0.67. The "metabolic range" (rest vs maximal exercise) does vary from 1 to 10, due to the prevalent influence of the skeletal muscle activity. Recent investigations have emphasized the fact that the allometric exponent is not unique (0.75), but it should be subjected to statistical variability, both in standard and in maximal exercise.

ABSTRACT

BACKGROUND: The number of homeless people of any country is a major social and health issue, but to date only a few descriptive and focused studies have been undertaken in Brazil on the matter. METHOD: In order to fill this gap, a cross-sectional study was carried out in a random representative sample (n=330) out of 1,977 homeless people lodged in the five public hostels of the Rio de Janeiro metropolitan area. Full data were collected by two trained researchers in a face-to-face interview with 319 (96.7 %) out of the 330 lodgers, using the CIDI (Composite International Development Interview) to assess psychiatric diagnosis. RESULTS: The main findings concern prevalence rate of major mental illness, which was 19.4% for the 12 months before data collection, and 22.6% lifetime prevalence rate. Other 12-month prevalence rates were 31% for alcohol abuse/dependence, 4.1% for drug abuse/addiction, 15% for severe cognitive impairment, and 49.2% for any mental disorder. The rate was 65.2% when organic mental disorders were added. Moreover, 23.9% of the sampled lodgers reported previous psychiatric admission. Their demographic characteristics were a mean age of 44.8 years old, 75.8% of them were male, 78.9% were single, 94.7% had a low level of schooling, and 79.2% were long-term unemployed. CONCLUSIONS: This study demonstrates the high rates of psychiatric morbidity in the homeless, but these rates are exceeded by the apparent poverty and illiteracy of the sample. Given the lack of delivery of community services now in Brazilian cities, this group is likely to be marginalized. Some special teams to assess the hostel residents need to be created.

ABSTRACT

An increase in the number of new cases of tuberculosis (TB) combined with poor clinical outcome was identified among HIV-infected injecting drug users attending a large HIV unit in central Lisbon. A retrospective epidemiological and laboratory study was conducted to review all newly diagnosed cases of TB from 1995 to 1996 in the HIV unit. Results showed that from 1995 to 1996, 63% (109/173) of the Mycobacterium tuberculosis isolates from HIV-infected patients were resistant to one or more anti-tuberculosis drugs; 89% (95) of these were multidrug-resistant, i.e., resistant to at least isoniazid and rifampicin. Eighty percent of the multidrug-resistant strains (MDR) available for restriction fragment length polymorphism (RFLP) DNA fingerprinting clustered into one of two large clusters. Epidemiological data support the conclusion that the transmission of MDR-TB occurred among HIV-infected injecting drug users exposed to infectious TB cases on open wards in the HIV unit. Improved infection control measures on the HIV unit and the use of empirical therapy with six drugs once patients were suspected to have TB, reduced the incidence of MDR-TB from 42% of TB cases in 1996 to 11% in 1999.

ABSTRACT

BACKGROUND: A fluorescence spectrometer has been constructed to study in vitro and in vivo fluorescence of human lenses. This instrument can measure fluorescence emission spectra, which can be useful in the characterisation of the lens endogenous fluorophores and evaluation of the feasibility of fluorescence measurement as a non-invasive marker for diabetes. The spectrometer allows determination of the optimum excitation and emission wavelengths, which can be used in simpler instrumentation for monitoring purposes. METHODS: To est the application in such studies a homogeneous group of type II diabetic subjects and normal controls was studied. For each subject the fluorescence emission spectra was measured using a spectrometer prototype consisting of a modified slit lamp coupled to a optical multichannel analyser (OMA). The incorporation of narrow-band filters allows the selection of three different excitation wavelengths: 404 nm, 436 nm and 485 nm. RESULTS: With both in vitro and in vivo measurements, no significant differences were found between diabetic and normal lenses concerning the wavelength of maximum emission of fluorescence. However, the spectra (lambda(exc)=436 nm) between 480 and 550 nm were better defined with diabetic lenses. Using ratios of fluorescence intensity at two different wavelengths (490/610, 510/610, and 550/610) allows for good discrimination between normal controls and diabetic patients. The use of ratios largely removes the effects due to attenuation of excitation light and emitted fluorescence. CONCLUSIONS: The non-invasive evaluation of lens fluorescence is proposed as early indicator of ocular complications associated with diabetes.

ABSTRACT

Two different series of patients with Infectious Endocarditis (IE), hospitalized in the same ward of Curry Cabral Hospital in Lisbon, are presented and compared. The two series were separated by a ten-year period--the first included patients observed from 1970 to 1976 and the second from 1988 to 1998. In the first series (20 patients), IE occurred mainly in patients with previous cardiac valvular lesion, the course was subacute and Streptococcus viridans was the predominant agent. In the last series (65 patients), most of the patients were young and had no previous valvular lesions. Right side endocarditis predominated and the course was acute. Most of patients were drug addicts and had HIV infection. Staphylococcus aureus was the predominant agent. The ages of the two series were significantly different (p < 0.005). The diagnostic value of transthoracic and transesophageal echocardiography is stressed. The details of the evolution of patients with HIV infection are presented according to the values of CD4+ lymphocyte counts. The relatively good prognosis of IE in drug addicts with antibiotic treatment, even with HIV infection, is emphasized.

ABSTRACT

The authors describe a clinical case of AIDS presented by three opportunistic infections (esophageal candidiasis, tuberculosis and atypical mycobacteriosis) and a dermatological manifestation--acanthosis nigricans--not described in medical literature as accompanying those entities. The exclusion of most common etiologies of acanthosis nigricans and its regression following treatment for those infections suggests that with AIDS it behaves like a paraneoplastic syndrome. Screening for HIV antibodies should be the rule whenever this dermatological manifestation is present.
