Abstract
Although rare, Angiostrongylus costaricensis infection may be a more prevalent etiology of inflammatory bowel disease than ulcerative colitis and Chron's disease in endemic areas in Central and South America. The present study reviewed the occurrence of A. costaricensis in Brazil, its clinical presentation and pathology; and proposed diagnostic criteria and case definitions for abdominal angiostrongyliasis (AA). Southern and southeastern Brazilian regions are the main endemic areas, and AA affects both genders and all age groups. A review of all 23 published reports of 51 Brazilian patients highlighted the following features that were subsequently classified as minor diagnostic criteria: abdominal pain, palpable mass in the right lower abdominal quadrant, history of exposure, ileocecal tumor, and intestinal perforation with wall thickening. Proposed major criteria include right lower quadrant abdominal pain, blood eosinophilia, positive serology (antibody detection), intense eosinophilic infiltration that involves all strata of the intestinal wall, eosinophilic granulomatous reaction, and eosinophilic vasculitis. In addition to the definitions of suspected and possible cases according to increasing strength of evidence of this infection, demonstration of worms/eggs/larvae in tissues or Angiostrongylus DNA in tissues or serum are required for a confirmed diagnosis. The application of the proposed criteria and definitions may improve patient management, epidemiologic surveillance, and identification of new endemic areas.

Abstract
Background Hyperinsulinemic hypoglycemia is the most common cause of severe and persistent hypoglycemia in neonates and children. It is a heterogeneous condition with dysregulated insulin secretion, which persists in the presence of low blood glucose levels. Case presentation We report a case of a 15 year-old male with hyperinsulinemic hypoglycemia, who underwent a subtotal pancreatectomy after inadequate response to medical therapy. Pathological examination was positive for nesidioblastosis (diffuse β-cell hyperplasia by H-E and immunohistochemical techniques). The patient’s blood glucose levels normalized after surgery and he remains asymptomatic after 1 year of follow-up. The systematic review allowed us to identify 41 adolescents from a total of 205 cases reported in 22 manuscripts, from a total of 454 found in the original search done in PubMed and Lilacs. Conclusions Although very well reported in children, hyperinsulinemic hypoglycemia can occur in adolescents or young adults, as it happens in our reported case. These patients can be seen, treated and reported by pediatricians or adult teams either way due to the wide age range used to define adolescence. Most of them do not respond to medical treatment, and subtotal distal pancreatectomy has become the elected procedure with excellent long-term response in the vast majority.

Abstract
Persistence and colonization by tree species in an environment following a fire depends on the effects on seed germination and seedling development. We used seeds of Kielmeyera coriacea and Qualea parviflora as a model to test the effects of high temperatures on germination and initial development of tree seedlings. We exposed the seeds to heat flow (70, 100, 130, 150 or 170 °C) for 2 or 5 min and compared the germination with that of unheated seeds (control). Seedlings were then harvested after 3, 7 or 15 days to evaluate aerial and root mass, root:shoot ratio, presence of cotyledon opening, true leaves, and secondary roots. We found no effect on germination for seeds exposed to temperatures ≥150 °C. However, germination was significantly reduced for seeds exposed to 100 °C for both 2 and 5 min. The mass of 15-day-old K. coriacea seedlings was smaller when seeds were heated at 70 °C for 5 min or at temperatures higher or equal to 100 °C. Qualea parviflora seedlings did not show any difference in mass, but there were marginal differences in the presence of roots and the opening of cotyledons. Kielmeyera coriacea seedlings allocated biomass faster than Q. parviflora. High temperatures affect both quantity and quality of germinable seeds, as well as biomass allocation during initial seedling development. These factors may explain the decrease in seedlings observed after fire, suggesting a bottleneck effect that influences population dynamics and species persistence in systems with frequent fires.

Abstract
The study aimed to estimate the prevalence of sexually transmissible infections (STIs) and associated factors in women in quilombola (maroon) communities in Brazil. This was a population-based cross-sectional study of quilombola women from March 2017 to January 2019. A questionnaire was used with sociodemographic, behavioral, and clinical information. A gynecological examination was performed for the collection of uterine cervical cells for oncotic cytology and the detection of Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, and human papillomavirus (HPV) via polymerase chain reaction. Rapid tests for HIV and syphilis were performed. The main outcome was defined as infection with one or more sexually transmissible pathogens. The analysis used chi-square test and hierarchical logistic regression. From a total of 380 women, 352 (92.6%) were included in the study. Prevalence of at least one STI was 18.5% (95%CI: 14.76-22.85). The highest prevalence was for HPV, with 11.1%, followed by 6.3% for T. vaginalis and 4.3% for C. trachomatis. There were no cases of N. gonorrhoeae. Prevalence was 0.3% for HIV and 4.3% for syphilis. Cervical-vaginal cytology was altered in 7.7% of the women. Detection of one or more STIs was significantly associated with age 25 to 44 years (OR = 2.33; 95%CI: 1.05-5.18), alcohol consumption (OR = 1.96; 95%CI: 1.06-3.64), altered cervical cytology (OR = 3.96; 95%CI: 1.65-9.48), and bacterial vaginosis (OR = 3.61; 95%CI: 2.01-6.47). Quilombola women showed high prevalence of one or more STIs, emphasizing the importance of organizing prevention strategies targeted to these women.

Abstract
Background Clinical improvements following highly active antiretroviral therapy (HAART) may increase high-risk behaviors resulting in sexually transmitted infections (STI). Optimism related to the success of HAART in slowing disease progression, reducing viral load, and improving health status might be important factors for increasing sexual risk behaviors such as less use of condoms. Objective To determine the prevalence of Chlamydia trachomatis, Neisseria gonorrhoeae, syphilis, hepatitis B and C, high-risk HPV, and cervical cytological abnormalities among women living with HIV (WLHIV) who attended a Reference Center for STI/AIDS in Brazil. Methods A cross-sectional study was conducted among 151 WLHIV attending an STI Clinic in Vitória city, Brazil. A structured questionnaire, including demographic, behavioral, and clinical information, was used for data collection. Serological tests for HIV, syphilis, hepatitis C and B, CD4 counts, and viral load determination were performed. Cervical samples were collected for cytology and real-time PCR for HPV,Chlamydia, and Neisseria gonorrhoeae. Results In this study, 59% of women had at least one diagnosed STI at the time of the first clinic visit; 31% had clinical forms of anogenital HPV, 10% syphilis, 8%Neisseria gonorrhoeae, 5.0% trichomoniasis, 3% Chlamydia trachomatis, 1% hepatitis B, and 1% hepatitis C; 6.7% of the women presented with cervical cytological abnormalities. Furthermore, 46.3% of women had HR-HPV, and 17.6% had HPV 16/18. Only 5% of the women had a CD4 count <200 cells/mm3, 61.6% had undetectable HIV viral load, and 81.3% were currently on HAART. Conclusion A high prevalence of STI and HR-HPV infections were observed among HIV-infected women in this investigation. Prevention programs need to focus on counseling WLHIV and their regular partners with focused interventions such as couples counseling and education programs.

Abstract
Pulmonary artery aneurysm is a disorder of varying etiology and should be diagnosed early for appropriate interventions. A 45-year-old man was hospitalized for chest pain, dyspnea, cough, chills, diarrhea, and vomiting, which had started 3 weeks before admission. Physical examination indicated a reduced vesicular murmur in the right hemithorax. A chest x-ray performed indicated a pneumothorax and pulmonary abscess in the right hemithorax. Thoracostomy released abundant purulent and fetid fluid. Direct examination of the pleural fluid using saline revealed structures similar to Trichomonas. Non-contrast chest computed tomography revealed right pneumothorax along with an irregular cavitation located at the pleuropulmonary interface of the posterior margin of the right lower lobe. A pleurostomy was performed. On the second postoperative day, the patient suffered a sudden major hemorrhage through the surgical wound and died on the way to the operating room. The autopsy revealed an abscess and ruptured aneurysm of the lower lobar artery in the lower right lung. Microscopic examination revealed extensive liquefactive necrosis associated with purulent inflammation and the presence of filamentous fungi and spores. This case can be characterized as a severe disorder that requires early diagnosis to achieve a good therapeutic response and to avoid fatal outcomes.

Abstract
BACKGROUND Most people who make the transition to renal replacement therapy (RRT) are treated with a fixed dose thrice-weekly hemodialysis réegimen, without considering their residual kidney function (RKF). Recent papers inform us that incremental hemodialysis is associated with preservation of RKF, whenever compared with conventional hemodialysis. The objective of the present controlled randomized trial (RCT) is to determine if start HD with one sessions per week (1-Wk/HD), it is associated with better patient survival and other safety parameters. METHODS/DESIGN IHDIP is a multicenter RCT experimental open trial. It is randomized in a 1:1 ratio and controlled through usual clinical practice, with a low intervention level and non-commercial. It includes 152 incident patients older than 18 years, with a RRF of ≥4 ml/min/1.73 m2, measured by renal clearance of urea (KrU). The intervention group includes 76 patients who will start with incremental HD (1-Wk/HD). The control group includes 76 patients who will start with thrice-weekly hemodialysis régimen. The primary outcome is assessing the survival rate, while the secondary outcomes are the morbidity rate, the clinical parameters, the quality of life and the efficiency. DISCUSSION This study will enable to know the number of sessions a patient should receive when starting HD, depending on his RRF. The potentially important clinical and financial implications of incremental hemodialysis warrant this RCT. TRIAL REGISTRATION U.S. National Institutes of Health, ClinicalTrials.gov .

Abstract
Although the Cerrado vegetation is adapted to fire, anthropogenic fires may impair the reproduction of some species. This study aimed to test the role of fruits of Qualea multiflora and their position in the tree crown in protecting the seeds during fires. Ten trees were selected in an area protected from fire (NB) and ten in a biannually burned area (B). Fruits were counted before the 2008 fire and weekly thereafter for 5 weeks. Fruit dehiscence, damage and position in the tree crown were recorded. Seed germination was assessed for seeds from both areas. In NB, 5.7% of fruits were located higher than 2 m, while in B 49.5% were located at this height. One week after the fire, the proportion of dehiscent fruits was lower in NB (19.5%) than in B (34.5%). Five weeks after the fire, all fruits in NB had dispersed their seeds, whereas in B only 47% of the fruits had. Immediately before the fire, the germination rate of seeds collected in NB was 80% (0-1 m), 97% (1-2 m) and 92% (≥2 m). Fifteen days after the fire, the germination rate of seeds in the B area was 3% (0-1 m), 13% (1-2 m) and 78% (≥2 m). Protection of Q. multiflora seeds from high temperatures is related to the fruit position in the tree crown rather than to fruit protection. Therefore, the results suggest that fire may alter the recruitment of new individuals.

Abstract
OBJECTIVE to know the epidemiological profile of patients undergoing surgery for well-differentiated thyroid carcinoma at the Cassiano Antônio Moraes University Hospital of the Federal University of Espírito Santo, as well as the oncological results and the main postoperative complications. METHODS we conducted a cross-sectional, retrospective study of patients with well-differentiated thyroid carcinoma (WDTC) operated from January 2008 to December 2015. RESULTS During the study period, 95 of the 353 patients undergoing surgical treatment of the thyroid gland had WDTC. Papillary carcinoma was the most frequent (91.57%). Total thyroidectomy not associated with cervical emptying was the most frequent surgical procedure (65.26%). Postoperative complications occurred in 6.31% of patients, hematoma being the most frequent. The mean follow-up time was 36.9 months. Relapse occurred in four patients (4.21%), being locoregional in all cases. The prognostic factors analyzed, such as gender, age, tumor size, lymph node involvement, staging, type of surgery, histology and complementary iodine therapy did not show statistical significance. CONCLUSION papillary carcinoma was the most common thyroid malignant neoplasm, affecting women in the 49-year-old age group more frequently. Loco-regional recurrence occurred in four patients. Hematoma was the most frequent complication.

Anal specimens from HIV-positive men and women were collected during a regular visit and they were used for cytology and histopathology tests, as well as for HPV molecular identification. Results A total of 223 patients (143 females and 80 males) were enrolled in the study and, HPV was identified in 68.6% of the sample. The frequency of HR-HPV, HPV16/18 and multiple HPV infection were similar in both groups. The upstream regulatory region (URR) sequencing was carried out in 38 samples identified as HPV16-positive, and European variants were the most frequent (69.2%), followed by Africans (25.6%) and Asiatic-Americans (5.1%). Having more than 20 sexual partners was associated with multiple HPV infection (p = 0.000) while, anal sex and the first intercourse before 15 years of age was a risk factor for any HPV infection (p = 0.001). Being MSM (men who have sex with men) was a risk factor for any HPV and multiple infections (p = 0.002). The CD4 count >500 cells/mm3 was a protective factor for the HPV16/18 (p = 0.048) and multiple infections (p = 0.023), and the undetectable viral load and HAART treatment were both protective for any HPV (p = 0.010), HR-HPV (p = 0.091) and multiple infections (p = 0.006). Abnormal anoscopy was found in 23.7% (53/223) of the total number of patients, and this was significantly associated with all types of investigated HPV infections (p<0.0001). Conclusions In this study, anal HPV infection was common among young HIV-positive men and women, particularly in MSM. Anal cancer screening in patients at risk, such as those who are HIV-positive, and mainly those with anal HPV infection and a history of STI, will increase the likelihood of detecting anal intraepithelial neoplasia.

Abstract
INTRODUCTION This study aimed to determine the dislocation and reoperation rate, functional outcomes, and the survival rate of the unique subset of very old but lucid and independent patients with hip fractures following a total hip arthroplasty (THA) and geriatric team-coordinated perioperative care. METHOD Between 2000 and 2006, previously independent ambulatory patients ≥80 years old presenting with an intracapsular hip fracture were given THAs under the care of an integrated orthopedic surgery-geriatric service. Their fracture-related complications, ambulation, mental status, and survival were followed for 5 to 11 years postinjury. RESULTS Five years postinjury, 57 (61.3%) patients of the original study group were living. In all, 3 (3.2%) patients had postoperative hip dislocations (and 2 patients had dislocation twice) and 2 reoperations were needed within the first postoperative month. There were no hip dislocations or reoperations after the first year. Radiographs obtained on 88% of the surviving patients at 5 years postoperatively showed that all remained unchanged from their immediate postoperative images. Nearly half of the patients were still able to ambulate as they did preoperatively and their mixed-model equation was statistically unchanged. CONCLUSION This study of patients >80 years old with previously good functional status demonstrates that with appropriate surgical (best prosthesis, good operating technique, and regional anesthesia) and geriatric (pre- and postoperative assessments, close follow-up, medication adjustments, and fall-prevention instruction) care, they have few hip dislocations and reoperations, survive postfracture at least as long as their noninjured contemporaries, and continue to function and ambulate as they did prior to their injury.

Abstract
OBJECTIVES To determine iodine nutrition in the population and to correlate levels of iodine found in random samples of urine with pathological changes observed in thyroids collected in this population. MATERIALS AND METHODS Urinary iodine was determined in 30 random samples of urine and the pathological study was carried out in 55 thyroid glands from corpses received by the Department of Forensic Medicine of Vitória, Espírito Santo, Brazil from May to August 2011. RESULTS In 29 urine samples (96.7%) urinary iodine was above the maximum limit recommended by the World Health Organization (WHO), of 300 mg/L. Fourteen thyroids (25.5%) showed the presence of histological changes compatible with thyroiditis. Higher levels of iodine in urine were observed in females and in of thyroid that showed inflammation (thyroiditis). CONCLUSIONS We conclude that, in this population, there is excess iodine intake, and greater incidence of inflammatory thyroid disease.

Abstract
The aims of this study were to evaluate the effects of nandrolone (ND) on cardiac inflammatory cytokines, ACE activity, troponin I, and the sensitivity of the Bezold-Jarisch reflex (BJR). Male Wistar rats were administered either ND (20 mg/kg; DECA) or vehicle (control animals; CONT) for 4 weeks. BJR was analyzed by measuring the bradycardia and hypotension responses elicited by serotonin administration (2-32 μg/kg). Mean arterial pressure (MAP) was assessed and myocyte hypertrophy was determined by the heart weight/body weight ratio and by morphometric analysis. Matrix collagen deposition was assessed by histological analysis of the picrosirius red-stained samples. Mesenteric vascular reactivity was performed and central venous pressure (CVP) evaluated. Cardiac inflammatory cytokine levels and angiotensin-converting enzyme (ACE) activity were studied as well the biomarker of cardiac lesion, troponin I. DECA group showed enhancement of matrix type I collagen deposition (p < 0.01) and cardiac ACE activity (p < 0.01) compared with the CONT. Interleukin (IL)-10 was reduced (p < 0.01) and pro-inflammatory cytokines (TNF-α and IL-6; p < 0.01) were increased in the DECA group compared with CONT. Cardiac injury was observed in the DECA group shown by the reduction in cardiac troponin I (p < 0.01) compared with the CONT group. Animals in the DECA group also developed myocyte hypertrophy and reduction of BJR sensitivity. The MAP of animals treated with ND reached hypertensive levels (p < 0.01; compared with CONT). No changes in CVP and vascular reactivity were observed in both experimental groups. We conclude that high doses of ND elicit cardiotoxic effects with cardiac remodelling and injury. Cardiac changes reduce the BJR sensitivity. Together, these abnormalities contributed to the development of hypertension in animals in the DECA group.

Abstract
There has been no previous prevalence study about of Sjögren's syndrome (SS) in Brazil. The aim was to evaluate the SS prevalence in a general population in Vitória, ES, Brazil. This was an epidemiological, observational, and cross-sectional study conducted on 1,205 randomized people, aged 18-65 years, who lived in Vitória. The subjects were screened for xerostomia and xerofphthalmia through home interviews. Those with sicca symptoms were asked to report to a hospital for further medical evaluation, unstimulated salivary flow, Schirmer I test, blood analysis and minor labial salivary biopsy. Sicca symptoms were found in 18% (217 subjects) of the sample. Of the 217 subjects with sicca symptoms, 127 (58%) were available for examination. In this sample, 61.7% were female and 46.8% were under medication. Sicca syndrome was confirmed in 12% by at least one examination (salivary flow or Schirmer I). Two patients (0.17%) matched four criteria according to American-European Criteria (95% CI = 0.020-0.5983).

Abstract
The use of microorganisms as bioindicators of soil health is quite a new feature, rarely considered for the soil health evaluation in chronically-polluted industrial sites, and still suffering of the bias related to the technique applied. In this work we applied a microbiological polyphasic approach, relying on soil indigenous microorganisms as bioindicators and combining culture-dependent and -independent methods, in order to evaluate soil health of four sites (1a, 1b, 2a and 2b) inside a chemical factory with a centenary activity. Functional as well as structural aspects were comprehensively considered. Results were related to the kind of pollutants found in each site. Heavy metal pollution was recorded in sites 1b and 2b, while both organic and inorganic substances were detected in sites 1a and 2a. Based on the chemical and physical properties of the four soils, site 1b and 2b grouped together, while 1a and 2a were separated from the others. The density of the culturable bacteria was very low in site 2a, where only gram-positive were found. According to the identification of culturable bacteria, site 2a showed the lowest similarity with the other sites. Microbial activity was detected only in sites 1b and 2b. PCR-DGGE (Denaturing Gradient Gel Electrophoresis), was performed on the culturable, total and active microbial communities. Consistently with the identification of culturable bacterial strains, the molecular profile of the culturable fraction of site 2a, was clearly separated from the molecular profiles of other sites in cluster analysis. Molecular fingerprintings of the whole and active bacterial communities differed among the sites, but clustered according to the pollutants present in each site. The presence of possible key species in each site has been discussed according to the whole and active species. Since the results obtained by microbiological analysis are consistent with the chemical data, we suggest that the use of this microbiological polyphasic approach and of microorganisms as intrinsic bioindicators, can be suitable for the evaluation of soil health.

Abstract
The peritoneal mesothelium is a barrier to ion transport in peritoneal dialysis. Cimetidine is an H2 receptor antagonist and a potent inhibitor of Na+/H+ antiporter, which is found in the plasma membranes of various cell types, including mesothelial cells. Recent reports linked Na+/H+ antiporter stimulation with increasing peritoneal fibroblast proliferation. The aim of the present study was to investigate by means of Ussing chamber experiments the effect of cimetidine on the transmesothelial electrical resistance (R) of isolated visceral sheep peritoneum. Peritoneal samples obtained from adult sheep were collected from the slaughterhouse and transferred in oxygenated Krebs-Ringer bicarbonate (KRB) solution to the laboratory within 30 minutes of the animal's death. The peritoneal tissue was transferred in a cooled KRB solution (4 degrees C, pH 7.5) bubbled with 95% O2/5% CO2. A planar sheet of the visceral peritoneum was mounted in an Ussing-type chamber and cimetidine (10(-3) mol/L) was added to the solution on the apical and basolateral sides. The R was measured before and for 15 minutes serially after addition of the cimetidine. Results presented are the means +/- standard error of the mean of 12 experiments. Addition of cimetidine basolaterally induced, within 1 minute, an increase in the deltaR of 35.97% +/- 12.01% (p < 0.05), which returned to baseline after 15 minutes. The action of cimetidine on the apical side of the membrane was similar, with a rapid rise in the deltaR of 47.3% +/- 16.4% (p < 0.05) and a subsequent decline to control values. The R is inversely correlated with membrane permeability. The results of the present study indicate a rapid action of cimetidine on the permeability of visceral sheep peritoneum, probably through inhibition of mesothelial Na+/H+ antiporter. The increase in R observed after addition of the cimetidine clearly indicates the existence of Na+/H+ antiporter on both sides of visceral sheep peritoneum. The clinical implications of our results should be further investigated.

Abstract
Senescence and chronic kidney disease (CKD) reduce progressively glomerular filtration rate (GFR), which usually results in an increase in potassium renal secretion. To evaluate whether the transtubular potassium concentration gradient (TTKG) is more accurate parameter for evaluating the renal secretion of this cation than using fractional excretion of potassium as its urinary secretion marker, we studied 55 subjects, 43 of them were healthy elderly volunteers and 12 were CKD patients. Exclusion criteria were: abnormal plasma potassium level or presence of any disease or drug that could induce alteration of balance of this electrolyte levels. All the subjects were on a diet with a potassium content around 50 mmol/day. The curves, which demonstrate the relationship between creatinine clearance and TTKG and the grade of correlation between these two parameters were analyzed in both groups. We found that the transtubular potassium concentration gradient had a significant negative correlation with the creatinine clearance level in the healthy elderly group, while there was no correlation in the CKD group.

Abstract
UNLABELLED Transtubular potassium concentration gradient (TTKG) is an index of potassium secretory activity in the distal tubule. Since water reabsorption takes place in the distal tubule as well, urine potassium concentration is a less accurate index evaluating distal K+ secretion because the effect of water is not taken into account on urine potassium concentrations. Potassium secretion and water reabsorption are strongly related to age and renal function. As a consequence, TTKG would be altered in both elderly individuals, as well as in patients with chronic renal failure (CRF). The aim of this study was to assess and compare TTKG in these two groups. PATIENTS & METHODS A total of 55 individuals were studied, 12 of them were patients with CRF and 43 healthy elderly subjects with normal renal function. Informed consent was obtained from all patients. Patients with diabetes mellitus, cardiac failure, cirrhosis, obstructive uropathy, hyperkalemia, hypokalemia, or taking any medication that could alter the potassium balance were excluded from the study. All subjects were on a diet containing 50 mmol of potassium intake daily (documented by a three-day dietary record). Plasma potassium, creatinine, urea, glucose and osmolality were measured in all as well. 24 h creatinine clearance (CrCl ) and TTKG were calculated. Statistical analysis was made using Student's t-test. RESULTS TTKG was significantly lower in the elderly group (4.2+/-1.9 vs 6.2+/-1.8 , P 0.005)Both groups had a significantly lower TTKG when compared to healthy young people (8+/-2). Plasma and urine potassium levels, as well as plasma osmolality were similar in the two groups. Only urine osmolality was lower in the CRF group (382+/-141 vs. 514+/-180, P=0.01) CONCLUSION Both old age and renal impairment lead to a reduced TTKG in comparison with young healthy people. Furthermore, TTKG is significantly lower in elderly healthy subjects compared to patients with CRF.

Abstract
The aim of this investigation was to study the frequency of visceral larva migrans (VLM) granulomas in autopsies at a Children's Reference Hospital in Vitoria, ES Brazil, where anti-Toxocara antibodies are frequently detected in the serum of children admitted at the hospital. Two liver fragments from 310 autopsies of children aged between 1 and 15 years were paraffin embedded, and sections were stained with hematoxylin and eosin and submitted to detection of Toxocara antigens using a rabbit anti-Toxocara serum. Among the 24 cases with granulomatous lesions, ten had eosinophil-rich granulomas positively stained with the anti-Toxocara serum. Some were typical epithelioid granulomas, with a positive reaction in multinucleated giant cells, epithelioid cells, or necrotic debris. The results showed that VLM granulomas are the most frequent granulomatous hepatitis in children in our county. This agrees with the high prevalence of anti-Toxocara antibodies in the serum of children admitted to the Children's Reference Hospital. The 3.2% frequency of liver VLM granulomas in autopsies is less than the 30-39% frequency of positive serology in these children, probably reflecting the low larval burden in infected children.

Abstract
BACKGROUND Helminth infections with larvae that migrate through the tissues have been considered risk factors for CNS infections. OBJECTIVES The present work was designed to investigate the prevalence of anti- TOXOCARA antibodies in the serum and/or in the cerebrospinal fluid (CSF) of children with infectious meningitis or meningoencephalitis and of a control group, without meningitis, admitted at the Children's Hospital NS Glória, Vitória, ES, Brazil. PATIENTS AND METHODS After adsorption with ASCARIS LUMBRICOIDES antigen, serum and/or cerebrospinal fluid of 381 inpatients (201 with meningitis and 180 without meningitis) were submitted to an ELISA IgG, for anti- TOXOCARA antibodies using secretion/excretion antigens of third stage larvae of T. CANIS. RESULTS No significant differences between the meningitis and the control groups were observed in the frequencies of positive tests for anti- TOXOCARA antibodies in the serum or CSF (respectively for the meningitis and control group: 33/103 or 32 % and 52/152 or 34.2 % for the serum, p = 0.821; 48/184 or 26.1 % and 23/121 or 19.0 % for the CSF; p = 0.196. CONCLUSION The results demonstrated that TOXOCARA infection, evaluated by detection of anti- TOXOCARA antibodies in serum or CSF, is not associated with viral or bacterial meningitis or meningoencephalitis in children in our country.

Abstract
OBJECTIVE To describe the cotton block method, an easy, inexpensive, 1-step method of obtaining a cell block after fine needle aspiration biopsy. STUDY DESIGN Before connection to a 10-mL syringe, the plastic hub of a 22-23-gauge needle is filled with the 3-4-mm, woolly tip of a cotton bud. Aspiration is performed as described elsewhere. After smear preparation, the material remaining in the needle and the material retained in the cotton wool mesh are immediately fixed by aspiration ofa fixative fluid (70% alcoholic formaldehyde-acetic acid). After fixation, the cotton tip is removed and routinely processed for paraffin embedding, and the sections are stained by routine methods used in cytopathology. RESULTS The results demonstrate that the amount and quality of material obtained in the cotton wool tip is similar to that in the traditional cell block obtained from the pellet after centrifugation of aspirated fluid. CONCLUSION The method is easy to perform and cost effective and is a rapid way to prepare cell blocks of high quality, allowing special staining techniques and improving cytohistologic correlation.

Abstract
OBJECTIVE Patients on peritoneal dialysis (PD) can develop uremic symptoms as their residual renal function declines. In this retrospective study, we assessed the effect of increasing the dose of dialysis in patients who developed uremic symptoms. METHODS Patients on PD who had an increase in their dialysis dose due to either the appearance of uremic symptoms or to worsening biochemical parameters were included in this study. These patients had to have been on PD for at least 6 months before and after the increase in their dialysis dose. Patients whose dialysis dose was increased after the initial Adequest (done within 2-3 months of starting PD) findings or for reasons other than underdialysis were excluded from this study. The symptoms studied in 104 patients included fatigue, anorexia, insomnia, pruritus and nausea. The presence or absence of theses symptoms was evaluated before and after the increase in the dialysis volume. Several clinical and laboratory data including the adequacy results were compared before and after the increase in dialysis dose. RESULTS Patients were on PD for 24.6+/-16 months when dialysis dose was increased. Eighty-five (82%) of them were on continuous ambulatory peritoneal dialysis (CAPD) while the remaining were on continuous cycler peritoneal dialysis (CCPD). Fatigue was the most common symptom that led to an increase in the dialysis dose (64%). The prevalence of all the symptoms studied decreased significantly after the increase in dose of dialysis. The weekly peritoneal creatinine clearance increased from 47.35+/-0.88 to 57.34+/-1.401 (P < 0.0001) and the weekly Kt/V increased from 1.8+/-0.03 to 2.27+/-0.05 (P < 0.0001). The daily urine volume and the residual GFR decreased from 318.7+/-36.4 to 151.9+/-22.8 ml/day (P < 0.0001) and 2.05+/-0.2 to 0.82+/-0.12 ml/min (P < 0.0001) respectively during the study period. CONCLUSION The prevalence of all uremic symptoms decreased significantly after the daily dialysate volume was increased. The improvement in symptoms despite the decline in residual function emphasizes the beneficial effect of increased dialysate volume, which produced a significantly higher peritoneal creatinine clearance and Kt/V after the change in the PD prescription.

Abstract
OBJECTIVE The aim of this report is to describe a fatal disseminated thrombotic micoangiopathy with renal, pancreatic, and cerebral involvement in a patient with recently diagnosed adult's Still disease (ASD). CASE REPORT A previously healthy 15 year old girl was admitted to our hospital. According to the clinical and laboratory data the diagnosis of adult's still Disease was established. The treatment was begun and few days after an initial improvement a sudden neurologic deterioration with coma and seizures has occurred. Hours later the patient died. Clinical, laboratorial, and pathologic data will be presented. CONCLUSION To our knowledge this is the second description of a fatal disseminated cerebral thrombotic microangiopathy in a patient with adult's Still disease, but with a much more fulminating evolution than previously reported. Some etiopathogenic mechanisms could be shared in these two disorders explaining this coexistence.

Abstract
Renal cell carcinoma is a rare but serious complication in ESRD patients. In these patients the incidence of renal cell carcinoma (RCC) is 20-40 times higher than in the general population. We performed a retrospective study to measure the incidence rate, prevalence, characteristics and survival among our peritoneal dialysis (PD) patients diagnosed with renal cell carcinoma. The study was carried out among 607 patients who were on the PD program from January 1997 to June 2002. RCC was detected in eight patients (four males and four females) with mean age of 52.1 +/- 10.6 years. Among these eight patients four were new cases that were diagnosed before the patients were started on dialysis (three in native kidneys and one in a transplanted kidney). In the other four patients the RCC was diagnosed after they had been on dialysis for 33-204 months (mean 60.75 +/- 50.48). We found an incidence rate of 1.3 per 1000 patients per year and a prevalence of 1.3%. Six of the eight patients had renal cysts. Tumor size was less than 7 cm in seven patients and in the other patient it was 8.5 cm. Seven of eight patients were alive at the time of study with a survival time ranging from 3-138 months (mean 122.25 +/- 88.2) months. In one patient, the RCC metastasised to the scalp, and, in two other patients, the tumors subsequently involved the second kidney. A cardiovascular complication was the cause of one death. Two patients received a renal transplant 36 and 66 months after diagnosis. We conclude that despite the low rate of metastases and mortality in our study, regular ultrasonography should be added to the follow-up of PD patients. Renal transplantation can be considered in these ESRD patients with RCC; however, close follow-up for metastases is recommended.

Abstract
OBJETIVO: O propósito do presente estudo é analisar as dificuldades quanto ao diagnóstico, avaliação prognóstica e conduta em sete pacientes portadores de tumores neuroendócrinos do pâncreas (apudomas), estudados na última década, comparando os resultados com aqueles discutidos na literatura. MÉTODO: A idade dos pacientes variou de 15 a 66 anos, com média de 38,4 anos. Todos foram submetidos a alguma forma de ressecção pancreática por tumores neuroendócrinos. Os exames histológicos foram feitos pelas técnicas tradicionais e por imuno-histoquímica. RESULTADOS: Três pacientes tiveram um diagnóstico inespecífico de tumor neuroendócrino; dois de vipoma e dois de gastrinoma. As síndromes não se manifestaram claramente, ainda que cada caso tenha tido um rótulo diagnóstico. Os exames por imuno-histoquímica demonstraram a presença de múltiplos hormônios, mas por falta de sintomas clínicos, as correlações ficaram prejudicadas na maioria dos casos, havendo correlação somente em caso de gastrinoma. Um paciente faleceu no pós-operatório; um sobreviveu sete anos e cinco estão vivos, com sobrevida variando entre três e cinco anos. CONCLUSÕES: Não houve uma manifestação sindrômica evidente, porém a sobrevida dos pacientes tem sido compatível com os dados de literatura.

Abstract
Chronic obstructive bronchiolitis with organizing lung disease is an anatomoradioclinical entity characterized by nonspecific inflammation associated with recurrent migratory minimally dense alveolar opacities on the chest x-ray poorly responsive to corticosteroid therapy. Excepting this typical presentation, other clinical forms may occur. We report the cases of two patients with an exceptional localized presentation raising the differential diagnosis of lung cancer.

Abstract
Pancreatic neuroendocrine tumors are rare in von Hippel-Lindau disease, most often asymptomatic, nonfunctioning, non secreting, and benign. We report a case of low grade malignant pancreatic, secreting and asymptomatic neuroendocrine tumors, occurring in a 27 year old woman in the setting von Hippel-Lindau disease with recurrent pheochromocytoma, retinal and medullary hemangioblastomas, paraganglioma of the carotid body and ovarian cystadenoma. Neuroendocrine pancreatic tumors of von Hippel-Lindau disease are often constituted by clear cells, in the contrary of other neuroendocrine tumors of the pancreas. Occurrence of a pancreatic neuroendocrine tumor, especially in association with pheochromocytoma, may be misdiagnosed with a type 2 multiple endocrine neoplasia syndrom instead of von Hippel-Lindau disease.

Abstract
Little is known about preexisting lesions in livers of children with pyogenic liver abscess (PLA). Study of these lesions may elucidate possible predisposing factors for the disease. In Vitória, state of Espirito Santo, Brazil, PLA in children is frequently associated with helminthic infections and eosinophilia. We hypothesize that nematode infection with larvae migrating through the liver is a predisposing factor for PLA, because the infection induces immunomodulation and likely trapping of bacteria in liver granulomas. In this report, we describe observations of 22 cases of PLA in children studied at autopsy (16 cases) or in surgical biopsies (6 cases), including 17 boys and 5 girls ranging in age from 1 to 13 years (mean 4.6 years, median 3.5 years). Multiple abscesses in both lobes were found in 13 cases and a single abscess was found in the right lobe in 10 cases. All cases showed histologically classical pyogenic inflammation without morphological evidence of amoebiasis. In six cases there were granulomas similar to those caused by larva migrans visceralis (from Toxocara or other nematodes) in liver tissue not affected by the abscess. Nematode antigens in central areas of necrosis of granuloma in all six cases and fragments of a larva, possibly of Toxocara, were found on samples immunohistochemically stained with polyclonal anti-Toxocara antibodies. There were numerous eosinophils in abscesses with Charcot-Leyden crystals. Eosinophils were found frequently in portal triads far from the abscess wall. In four cases, in which bile duct ascariasis was found, worms were noted in the bile ducts, and eggs were found in liver parenchyma surrounding the abscess in two cases. Foreign-body granulomas were found in one case in which penetrating trauma was the cause of abscess. In one case there was one histiocytic granuloma whose origin was not determined. The observation of six cases of granuloma similar to larva migrans visceralis (or produced by other nematode larva) in liver tissue not directly affected by the abscess supports the hypothesis that helminth infections with larva migrating through the liver are a predisposing factor for pyogenic hepatic abscess in children.

Abstract
The present study investigated the involvement of the human cerebellum in the habituation of the acoustic startle response using PET. The startle response was elicited in seven young, healthy subjects by a tone presented via headphones. Startle responses were recorded from the right sternocleidomastoid muscle. Regional cerebral blood flow (rCBF) was assessed in nine scans and one startle stimulus was applied during each scan. The reduction of size of the sternocleidomastoid muscle response was correlated with changes in rCBF during the ongoing process of startle response habituation. A significant decrease of rCBF was found in the medial cerebellum. These data are consistent with an involvement of the medial parts of the human cerebellum in non-associative learning as proposed by previous animal studies.

Abstract
In this communication we describe for the first time the isolation of 7 iridoviruses from the toad Bufo marinus and an unknown species of frog Leptodactylus in Venezuela, South America. The viruses are icosahedral with electron-dense cores, each of which is surrounded by an inner membrane, capsid and a cell-derived envelope. The virus(es) have an average vertex to vertex diameter of 160 nm and replicate in the cytoplasm of a range of cell lines. Within the cytoplasm of infected cells, rarefied areas could be observed; structures lacked cellular organelles and contained complete, empty and developing viruses. Results from antigen-capture enzyme-linked immunosorbent assays (ELISA) with polyclonal antibody raised against epizootic haematopoietic necrosis virus (EHNV) indicated cross-reactivity between these isolates, Bohle iridovirus (BIV) and frog virus 3 (FV3). Comparison of polypeptide and genomic profiles indicated that the Venezuelan viruses shared many polypeptides of equivalent molecular weight with type species FV3. There were, however, differences between the group of Venezuelan viruses and FV3 and BIV. The viruses belongs to the family Iridoviridae and the genus Ranavirus.

Abstract
BACKGROUND Protrusion of the cortex through a bone flap in the course of surgery is a very serious event and, if it persists, the procedure must be suspended, the cause sought, and the problem resolved. CASE DESCRIPTION We report the case of a 13-year-old boy whose brain underwent sudden swelling during removal of a supratentorial cystic lesion. The operation was suspended at once and an emergency CT scan was performed. It revealed a large contralateral extradural hematoma, which was removed immediately. CONCLUSIONS We considered the following possible mechanisms of the emergency: bleeding of bone at the site of the supposed piercing by the headrest pin and/or a vacuum mechanism consequent upon removal of the large cystic lesion. Our aims are to emphasize the importance of gauging the thickness of a child's skull before fixing the head in the headrest, especially when chronic intracranial hypertension is present, and the need to suspend the operation for CT scanning in the event of uncontrollable brain swelling.

Abstract
Pyogenic liver abscess in children is uncommon in developed countries and there are few reports about the disease in developing countries including Brazil. As pyogenic liver abscesses in children are frequently diagnosed in Vitória (E. Santo State, Brazil), the records of admissions at the Children's Hospital (Hospital Infantil N.S. da Glória) were surveyed. Sixty-five cases of pyogenic liver abscess were observed over a period of three years, from May 1991 through April 1994 (mean of admissions of 2800 children/year). Fourty-seven cases occurred in boys (mean of ages 8.1 +/- 3.5 yr, median 8 yr) and 18 in girls (mean of ages 6.1 +/- 3.3 yr, median 7 yr) with a 2.7:1 male/female ratio. Predisposing factors were skin infections (23 cases), bile duct ascariasis (six cases), trauma (two cases) but in 30 cases a predisposing factor was not evident. Staphylococcus aureus was the bacteria most frequently isolated (16/29 examined). Entamoeba histolytica trophozoites were never found in the exudate of abscesses and cysts were found once in fecal examination. Clinical manifestations were similar to those observed in other reports about pyogenic liver abscess in children. There was a high frequency of intestinal helminth infection (80.6% of 36 cases in which a fecal examination was recorded) and eosinophilia in the peripheral blood (36.2% of 61 cases). In addition most cases came from the urban periphery of Vitória, where intestinal parasites are frequent. These data showed that the frequency of pyogenic liver abscess is higher in Vitória (one case/138 admissions) than in developed countries (25 cases or less/10,000 admissions in USA). We hypothesyse that the helminth infection (mainly with ascaris and toxocara), whose larvae migrate through the liver inducing granulomas, could enhance the localization of bacteria, increasing the risk for pyogenic liver abscess.

Abstract
A possible association of the acute toxemic form of schistosomiasis and pyogenic liver abscess (PLA) has been recently suggested. As in the west of the Espírito Santo state schistosomiasis is endemic and PLA are frequently diagnosed in the Children's Hospital of Vitória we reviewed the records of the Hospital during the period from May 1991 to April 1993 to: a) identify all cases of PLA in which Schistosoma mansoni infection was present and b) annotate the procedence of each case to verify if there is an association of the two diseases. 65 cases of PLA were recorded and 39 had the result of a stool examination, being three positive for Schistosoma mansoni (7.6%) and 26 for other helminth (mainly Ascaris and Trichocephalus). The procedence of the patients showed that only 7 (10.7%) came from endemic areas. These results show that an association of Schistosoma mansoni infection and PLA was not significative in the country, where the acute toxemic form is not frequent. The great majority of PLA in this study came from the urban periphery of Vitória, where transmission of schistosomiasis does not occur but intestinal helminth infections are extremely frequent. The great majority of PLA in this study came from the urban periphery of Vitória, where transmission of schistosomiasis does not occur but intestinal helminth infections are extremely frequent. As 40% of these PLA were cryptogenetic it is possible that the immunomodulation induced by intestinal parasites and the liver granulomas produced by the larvae of these helminths would be predisposing factors for pyogenic liver abscess.

Abstract
A case of fulminant hepatitis with microvesicular steatosis resembling Labrea's fever, diagnosed in Vitoria (ES) is reported. The 16 year old boy presented with severe epistaxis, agitation, jaundice and hemorrhagic vomiting and died two days after admission to the emergency unit of the University Hospital. The disease started five days before with fever, myalgias, dark urine and jaundice and progressed with psychic agitation, torpor and coma. The liver and spleen were not palpable. HBsAg was negative in the serum. The autopsy showed acute hepatitis with lytic necrosis confluent in the midzonal and periportal areas with massive microvesicular steatosis in the remaining hepatocytes. Mononuclear cells predominated in the exudate. The reticulum showed condensation in the necrotic areas without typical bands of collapse. The portal tracts were edematous with mononuclear infiltration and mild bile duct proliferation. Absence of cholestasis. Except for the confluent midzonal and periportal necrosis this case showed several clinical and morphological aspects of the Labrea fever described from the East Amazon, demonstrating that the anatomical picture of this disease probably is not in related to a factor peculiar to the Amazon region.

Abstract
Single photon emission computed tomography with technetium-99m-d, l-hexamethylpropyleneamineoxime was used to assess variations in regional cerebral blood flow during temporary clipping in the course of intracranial aneurysm surgery and during the postoperative period in 20 patients, 14 of whom underwent temporary clipping. Of these 14 patients (Group A), 9 had aneurysms of the anterior communicating artery, 2 had aneurysms of the middle cerebral artery, and 3 had aneurysms of the carotid siphon. Temporary clips were applied, according to the site of the lesion, on A1, on the trunk of the middle cerebral artery, or on the trunk of the internal carotid artery. The occlusion time ranged from 2 to 31 minutes. The six patients who did not undergo temporary clipping served as controls (Group B), as follows: three had aneurysms of the posterior communicating artery, one of the anterior communicating artery, one of the middle cerebral artery, and one of the internal carotid artery. All patients were investigated with cerebral single photon emission computed tomography preoperatively, perioperatively, and postoperatively. In all the patients of Group A, the preliminary results of the study show a sharp fall in the perfusion of the territories of the temporarily clipped parent vessel and practically a complete recovery within 2 to 7 days of surgery, with no significant neurological symptoms. No similar disturbance of perfusion was found in the patients of Group B.

Two cases of primary non-Hodgkin lymphoma of the liver are presented, with comments about the main clinical and pathological aspects of the disease based on literature review. Both patients were woman (19 and 62 years old) and presented the same complaints: severe weight loss and presence of fast growing abdominal mass. In both cases the histologic diagnosis showed a non-Hodgkin, diffuse, large cell lymphoma (centroblastic-centrocytic diffuse lymphoma) with intermediate grade of malignancy. One case (19 years) died before treatment. The autopsy showed a large solitary tumor (18 cm in diameter) in the right liver lobe and two small nodules (1 cm) in the subcutaneous tissue of the abdominal wall. The other case (62 years), was treated by partial hepatectomy and chemotherapy. There was a round, solitary tumor (8 cm in diameter) in the left lobe. The patient remains without manifestations of disease relapse 18 months after the treatment. In both cases the tumor did not spread to lymph nodes, spleen and other viscera.
