Clinical and serological follow up examinations were performed on 203 persons, from three to twenty years of age, from the otolaryngology department of a hospital in the city of Rio de Janeiro, with no symptomatology suggesting toxoplasmosis, but suffering from chronic tonsillitis. According to results obtained during the first indirect immunofluorescence tests, the patients were divided into following groups: Group I (non-reactive IgG and IgM), 98 persons (48.3%); Group II (1:16 ≤ IgG ≤ 1:256 and non-reactive IgM), 74 persons (36.5%); Group III (IgM ≥ 1:1024 and non-reactive IgM), 18 persons (8.8%), and Group IV (IgG and IgM reactive), 13 persons (6.4%). One to two years later, 131 (64.5%) of the 203 persons were reexamined by a second indirect immunofluorescence test. In the case of 66 persons (Group I) whose serum was non-reactive in the IgG and IgM classes during the first indirect immunofluorescence test, serum conversion was observed in aproximately 21.2%. in 65 individuals (49.6%), (Groups II, III and IV),with reactive serum in the IgG classes during the first indirect immunofluorescence test, the second reaction showed an increase in titres in 20% of the cases, a decrease in 67.7% of the cases, or no alterations in 12.3 of the cases. In the IgM class, all 131 sera were non-reactive at 116 dilution the second immunofluorescence test, including the 13 cases that had previously been reactive in the immunoglobulin class, Symptomatology suggesting toxoplasmosis was only observed in one case during the second testing, this patient's principal physical sign being hypertrophied lymph nodes. during this period, the Toxoplasma antibodies showed titres of IgG 1:32000 and non-reactive IgM, whilst one year previously, during the first test, these titres were IgG 1:1024 and IgM 1:64. Differences in the age, sex and skin coloring of patients were not statistically significant as regards alterations in the indirect immunofluorescence test titres.

Immunosuppressed Patients

Clinical and serological follow-up of 7 patients submitted to renal transplantation and presenting positive serological reactions to Chagas 'disease before immunossupression did not show significant changes in indirect immunofluorescence and complement fixation titres for Chagas ' disease, or signs and symptoms indicating exacerbation of the disease during follow- up. In addition, 18 of 66 recipients of renal transplants considered to be non-chagasic before immunosuppression showed at least one positive result to the indirect immunofluorescence test for Chagas ' disease during the study period. The results suggest that the immunosuppression State induced in chagasic patients submitted to renal transplant did notpromoted exacerbation of the chronic infection in these patients and not interfere with the serological response of chronic chagasics, thus permitting the use of these serologic reactions for diagnostic purposes in these cases. However, the positive results ofthe indirect immunofluorescence test in non- chagasic patients indicate the needforjudicious interpretation ofthe indirect immunofluorescence test for the diagnosis of Chagas' disease in renal transplanted patients.

From July 1984 to September 1986, 105 cases of American cutaneous leishmaniasis were studied in a locality closely situated to an urbanized area of the city of Rio de Janeiro, Brazil. Settement in this area was established at least 20 years ago but the first cases were noted six months prior to the beginning of this study. Cases were almost exlusively cutaneous and ulcerated, with one to six months of evolution. Montenegro's skin tests were positive in all cases and anti-Leishmania antibodies were detected by indirect immunofluorescence test in 74.3% of the patients. Parasites were demonstrated in 69.5% of cases. Domestic animals were easily found infected; 32% of the examined dogs and 30.8% of the examined equines were positive to the presence of Leishmania in cutaneous ulcerated lesions. Parasite isolates from human, dog andequines were immunologically characterized and identified as L. b. braziliensis. 73,0% of the sandfly population were Lutzomyia intermedia mainly caught on human baits and on domestic animals. Our observations suggest that this is an area of recent established L. b. braziliensis infection and that transmission probably occurs indoors or outdoors close to the houses.

Introduction. Cardiovascular (CV) diseases and bone fractures due to osteoporosis are the leading causes of death in the elderly. Objective. The aim of this study was to demonstrate a correlation between the overall risk for CV events, and low bone density in postmenopausal women, and its impact on the incidence of serious CV events. Methods. Our prospective study involved 300 postmenopausal women. All the examinees were divided into three groups based on their measured bone density: Group I - 84 examinees with osteoporosis; Group II - 115 examinees with osteopenia; and Group III - 101 examinees with normal bone density. In all examinees the overall ten-year risk for a fatal CV event was calculated using the SCORE system tables. Results. After a 36-month follow-up, CV events occurred in 19 (6.3%) examinees. Significant differences in the incidence of CV events were demonstrated between the patients with osteoporosis, osteopenia, and normal bone density (?2=28.7; p<0.001), as well as between those with a high and low CV risk (?2=22.6; p<0.001). Multivariate logistic regression analysis showed that smoking (OR: 2.23; 95% CI: 1.02 to 6.19; p=0.035), and increase of overall CV score (OR: 1.36; 95% CI: 1.17 to 1.58; p<0.001) are associated with increased CV event risk, while the increase of T score value is associated with decreased risk of CV event (OR: 0.42; 95% CI: 0.25 to 0.73; p=0.002). Conclusion. Measurement of bone density with a standard assessment of the total CV risk could be useful for selecting women who need intensive prevention and treatment of atherosclerosis.

The prognostic significance of pulmonary hypertension (PH) and the potential for reversibility in the setting of aortic stenosis (AS) have been debated. We examined the clinical correlates and prognostic significance of PH in high risk elderly patients with symptomatic severe AS undergoing transcatheter aortic valve implantation (AVI). AVI was performed in 143 patients. Adequate echocardiographic estimation of baseline pulmonary artery systolic pressure was available in 115 (80%). Patients were divided into 3 groups according to baseline pulmonary artery pressure estimated by transthoracic echocardiogram: I: <30 mmHg, II: 30 –50 mmHg and III: >50 mmHg. Clinical and echocardiographic follow-up was obtained at 1, 6 and 12 months after AVI. Group I consisted of 17 patients (15%), group II 58 patients (50%) and group III 40 patients (35%). At baseline the three groups were similar in terms of age, functional status, presence of severe pulmonary disease, aortic valve area and mean gradient. Patients with severe PH (group III) were more likely to have left ventricular dysfunction (LVEF <50%) than patients with mild to moderate PH (groups I and II) (52% vs. 21%, p=0.002) and had more severe mitral regurgitation (grade ≥ 3 in 68% vs. 41%, p =0.0002). At one month, systolic pulmonary artery pressure fell significantly in group III (11.0 ± 14.3 mmHg, p=0.0008) and this reduction was maintained at 6 months. However, the changes in group I (increase of 7.1 ± 8.7 mmHg, p=0.07) and group II (decrease of 0.9 ± 9.3 mmHg, p=0.53) were not significant. Mortality at one year following AVI was 21%, but was not related to severity of PH. Using group III as a reference, hazard ratios were 0.83 (95% CI: 0.24 –2.9) for group I and 0.88 (95% CI: 0.4 –1.9) for group II. In elderly patients with severe AS treated with transcatheter AVI, severe PH is associated with more depressed left ventricular function and more severe mitral regurgitation. Severe PH is associated with a significant and greater fall in pulmonary pressure following AVI and does not influence one year survival.

Rufino arrives in Rio de Janeiro between the last months of 1835 and the first days of 1836, one year after the great Muslim slave rebellion in Salvador. As a result, African Muslims became a main targets of police authorities in Rio de Janeiro, for some of the rebels had been sold, if slaves, or migrated, if freedpersons, to the capital of the Brazilian empire. Throughout the 1830s there were rumors and fear of slave rebellions. Marronage in the suburbs, slave flights, and resistance were rampant. The city and its hinterland were under heavy police surveillance. West Africans, like Rufino, were closely watched.

Abstract Background and Aims HCV is a worldwide cause of chronic liver disease, particularly in Egypt where the most prevalent is genotype 4. HCV-associated cirrhosis is the most common indication for orthotopic liver transplantation (OLT) among adults. HCV infection remains a problem after transplantation, and recurrent hepatic infection is the leading cause of graft failure. Little is known about the long-term effects of direct acting antiviral therapy in patients after liver transplantation. We examined the incidence and severity of liver transplantation rejection in patients treated for HCV, post liver transplantation, with DAAs relative to the incidence and severity of liver transplantation rejection in patients treated for HCV, post liver transplantation, with Interferon based therapy and patients who didn’t receive any treatment for HCV after transplantation. Patients and Methods The study was conducted on 90 patients who had underwent liver transplantation between 2010 and 2017 at Ain Shams Center for Organ Transplantation (ASCOT) with a minimum follow up period of 6 months. Patients were divided into three groups: group I included 16 patients that didn’t receive antiviral treatment after liver transplantation, group II included 20 patients that had received interferon based therapy after liver transplantation and group III included 54 patients that had received direct acting antivirals after liver transplantation. Results Amongst group I, 2 patients (12.5%) developed acute graft rejection while in group II 2 patients (10%) developed chronic graft rejection and in group III 6 patients (11.11%) developed chronic rejection. In group I, all the patients (100%) had developed rejection that was diagnosed within one year of liver transplantation. In group II, 2 patients (100%) developed chronic graft rejection which occurred after one year of liver transplantation, one of them was on treatment with peg interferon and the other had already completed treatment. In group III, 2 patients (40%) had developed chronic rejection within one year of transplantation, while 4 patients (60%) had developed chronic rejection after one year of transplantation. One patient (16.67%) had developed rejection on treatment while 5 patients (83.33%) had developed rejection after the end of treatment. Conclusion It was found that the incidence of chronic rejection was more in patients that had received antiviral treatment after liver transplantation, however no difference was noted between DAAs and peg-interferon. Chronic rejection was found to be more common when treatment was given over one year after liver transplantation (6 cases) as compared to within the 1st year (2 cases). This may be related to the withdrawal of immunosuppression treatment after one year of transplantation and maintenance on monotherapy.

Purpose To evaluate the effect of intravitreal triamcinolone acetonide on visual acuity and macular thickness using optical coherence tomography (OCT) in macular edema associated with various retinal vascular disorders. Methods This prospective nonrandomized clinical interventional study included 81 eyes (76 patients) comprised of Group I, 57 eyes (51 patients) with diabetic macular edema; Group II, 10 eyes (10 patients) with branch retinal vein occlusion; and Group III, 13 eyes (13 patients) with central retinal vein occlusion. All eyes received an intravitreal injection of 4 mg triamcinolone acetonide (with the solvent) in the operation theater under sterile conditions. Results Mean preinjection central macular thickness was 531.84±132 μm in Group I, 458.4±149 μm in Group II, and 750.81±148 μm in Group III. All groups showed a statistically significant decrease in mean central macular thickness at 1 month (300.7±119 μM in Group I, 218.2±99 μm in Group II, and 210.5 ±56 μm in Group III) and 3 months (253.19±109 μm in Group I, 187±47 μm in Group II, and 182±50 μm in Group III) after injection (p<0.05). Mean follow-up was 22±2.4 weeks. Mean visual acuity increased in all three groups (preoperative visual acuity in Group I, 1.2±0.4 logMAR units; Group II, 1.24±0.5 logMAR units; Group III, 1.1 ±0.4 logMAR units; 1 month postinjection in Group I, 0.88±0.3 logMAR units; Group II, 0.67±0.3 logMAR units; Group III, 0.86±0.4 logMAR units; 3 months postinjection in Group I, 0.84±0.4 logMAR units; Group II, 0.59±0.3 logMAR units; Group III, 0.82±0.5 logMAR units) (p<0.05). Forty-one eyes completed 6 months and 20 eyes completed 9 months follow-up. Twelve of 20 (41%) eyes in Group I, 2/6 (33%) eyes in Group II, 3/6 (50%) eyes in Group III, and 8/15 (53%) eyes in Group I, 1/3 (33%) eyes in Group II, and 2/2 (100%) eyes in Group III developed recurrence of macular edema with worsening of visual acuity at 6 and 9 months, respectively. Thirty-three (40.7%) eyes developed IOP elevation (at least one reading > 24 mmHg). One eye developed infective endophthalmitis. Conclusions Intravitreal injection of triamcinolone acetonide may be considered as an effective treatment for reducing macular thickening due to diffuse diabetic macular edema, venous occlusion associated macular edema, and may result in increase in visual acuity at least in the short term. Further follow-up and analysis is required to demonstrate its long-term efficacy.

This study aimed to analyze time trends in complementary feeding practices among children under one year of age in the city of Rio de Janeiro, Brazil, from 1998 to 2008. Based on comparable questions on food consumption in five surveys conducted in representative randomized samples of children in 1998 (n = 3,762), 2000 (n = 3,670), 2003 (n = 4,305), 2006 (n = 3,686), and 2008 (n = 2,621), 16 complementary feeding indicators were constructed. The percentage frequency of all indicators was estimated for each year of the study. Linear trend analyses were also conducted by means of multivariate regression models. All indicators of early complementary feeding decreased from 1998 to 2008. In the 6-11.9 month age group, there was a significant downward trend in the proportion of children receiving food with adequate consistency for their age, consumption of iron-rich foods, and overall adequacy of the diet. A significant upward trend in fruit consumption was observed. There was a decrease in the early complementary feeding, and generally a worsening of complementary feeding practices in children aged 6-11.9 months in Rio de Janeiro during the period studied.

Cerebrospinal fluid from 53 patients with clinical evidence of neurocysticercosis and 11 who suffered from several diseases were studied to evaluate the behaviour of indirect immunofluorescence test and some parameters of routine analysis. In neurocysticercosis there were pleocitosis in 88.7% of cases, eosinophilorrachia in 60.3%o, hyperproteinorrachia in 71.7% and hypoglucorrachia in 13.2%. The indirect immunofluorescence test was positive in 19.2% of cases but false-positive results were found when the samples showed xanthochromia or erythrocyte contamination. The authors discuss their results in comparison with those in literature and conclude that the immunofluorescent test is sensitive and useful in diagnosis of neurocysticercosis, except when the interferents previously mentioned are present.
