Abstract
Background Death from bacterial meningitis is rarely attributed to the actual event causing death. The present study therefore categorized and characterized the cause and time of death due to bacterial meningitis. Methods In a cohort of patients > 15 years of age with community acquired bacterial meningitis the medical records were reviewed, and a clinical cause of death categorized into six main categories: 1) CNS complications, 2) Systemic complications, 3) Combination of systemic and CNS complications, 4) Sudden death, 5) Withdrawal of care, or 6) Unknown. Results We identified 358 patients of which 84 (23%) died in-hospital. Causes of death were ascribed to CNS complications in 43%, Systemic complications in 39%, Combined CNS and systemic complications in 4%, Sudden death in 7% and withdrawal of care in 5%. Brain herniation, circulatory failure, intractable seizures and other brain injury were the most common specific causes of death within 14 days from admission (55%). Conclusion Fatal complications due to the primary infection – meningitis - is most common within 14 days of admission. The diversity of complications causing death in meningitis suggest that determining the clinical cause of death is essential to the evaluation of novel treatment strategies.

Abstract
OBJECTIVE biliopancreatic diversion with duodenal switch is a complex, malabsorptive procedure, associated with improved weight loss and metabolic control. Staged surgery with sleeve gastrectomy as the first stage is an option for reducing complications in superobese patients. However, some problems persist: large livers can hamper the surgical approach and complications such as leaks can be severe. Intestinal transit bipartition is a modified and simplified model of biliopancreatic diversion that complements sleeve gastrectomy. It is similar to the duodenal switch, but with less complexity and fewer nutritional consequences. This study assessed the feasibility and safety of isolated transit bipartition as the initial procedure in a two-step surgery to treat superobesity. METHODS this prospective study included 41 superobese patients, with mean BMI 54.5±3.5kg/m2. We performed a laparoscopic isolated transit bipartition as the first procedure in a new staged approach. We analyzed weight loss and complications during one year of follow-up. RESULTS we completed all the procedures by laparoscopy. After six months, the mean percent excess weight loss was 28%, remaining stable until the end of the study. There were no intraoperative difficulties. Half of the patients experienced early diarrhea, and three had marginal ulcers. There were no major surgical complications or deaths. CONCLUSION isolated laparoscopic transit bipartition is a new option for a staged approach in superobesity, which can provide a safer second procedure after effective weight loss over six months. It may be useful particularly in the management of patients with severe obesity.

Abstract
PURPOSE To investigate cardiac changes in young rats, whose mothers underwent autogenic fecal peritonitis, during organogenesis phase and to evaluate the role of intravenous administration of moxifloxacin and dexamethasone in preventing infection-related cardiac changes. METHODS A prospective histomorphometric study was performed on 29 hearts of Wistar four-month old rats. Animals were divided into three groups: Negative Control Group (NCG) included 9 subjects from healthy mothers; Positive Control Group (PCG) included 10 subjects from mothers with fecal peritonitis (intra-abdominal injection of 10% autogenic fecal suspension in the gestational period) and did not receive any treatment; and Intervention Group (IG), with 10 animals whose infected mothers received moxifloxacin and dexamethasone treatment 24 hours after induction of fecal peritonitis. RESULTS Nuclear count was higher in the IG group as compared to PCG (p = 0.0016) and in NCG as compared to PCG (p = 0.0380). There was no significant difference in nuclear counts between NCG and IG. CONCLUSION Induced autogenic fecal peritonitis in pregnant Wistar rats determined myocardial changes in young rats that could be avoided by the early administration of intravenous moxifloxacin and dexamethasone.

Abstract
PURPOSE To evaluate the response of aging rats with sepsis to two different antibiotic regimens. METHODS The study was conducted with 30 aging rats (18 month-old) with autologous feces peritonitis. The animals were divided into three groups: Group 0 received no therapeutic intervention (control), while Group 1 received a single dose of 40 mg/kg meropenem and Group 2 received a single dose of 20 mg/kg moxifloxacin. The intervention in both Groups was made 6 hours after induction of peritonitis. The animals were followed up to 15 days for evaluating morbidity and mortality. The weights at baseline were similar in all groups. RESULTS At the end of follow-up, weight loss was significantly greater (p=0.0045) in Group 0 (non-intervention controls). Culture from a blood sample at the end of follow-up was positive in all the animals in Group 0, in two animals in Group 1 and in four animals in Group 2. Morbidity/mortality was significantly higher in Group 0 compared to both Groups 1 and 2 (p=0.003) but the scores were not significantly different between Groups 1 and 2 (p=0.6967). CONCLUSION Both antibiotic regimens rendered promising results for the treatment of fecal peritonitis.

Abstract
BACKGROUND The prevalence of atherosclerosis is higher in HIV-positive people, who also experience it earlier than the general population. OBJECTIVES To assess and compare the prevalence of atherosclerosis evaluated by the intima-media thickness of carotid and femoral arteries, and by the ankle-brachial pressure index (ABPI) in HIV patients treated or not treated with protease inhibitors (PIs) and controls. METHODS Eighty HIV+ subjects (40 using PIs and 40 not using PIs) and 65 controls were included in the study. Atherosclerosis was diagnosed by (carotid and femoral) ITM measurement and ABPI. Classical risk factors for atherosclerosis and HIV were compared between the groups by statistical tests. A p ≤ 0.05 was considered significant. RESULTS An IMT > P75 or the presence of plaque was higher in the HIV+ than in the control group (37.5% vs 19%, p = 0.04). Comparative analysis showed a significant difference (p=0.014) in carotid IMT between HIV+ with PIs (0.71 ± 0.28 mm), without PIs 0.63 ± 0.11 mm and, and controls (0.59 ± 0.11 mm). There was no significant difference in femoral IMT between the groups or in ABPI between HIV+ subjects and controls. However, a significant difference (p=0.015) was found between HIV+ patients not treated with PIs (1.17 [1.08 - 1.23]), and controls 1.08 [1.07 - 1.17]). CONCLUSION In HIV patients, atherosclerosis is more prevalent and seems to occur earlier with particular characteristics compared with HIV-negative subjects.

Abstract
To report the frequencies of congenital hand diseases in patients who underwent surgery on a collective mobilization basis at SOS Hand, Recife, Pernambuco, between 2005 and 2009. Methods: Information was collected from 833 children and adolescents who were examined in eight missions. Results: Among the patients, 306 (36.7%) underwent surgery: 240 (78.4%) because of congenital malformation and 66 (21.6%) because of acquired lesions. The most frequent congenital malformations were: syndactyly, 72 cases (30.0%); polydactyly, 30 cases (12.5%); bifid thumb, 19 cases (7.9%); complex hand malformation, 14 cases (5.8%); cleft hand, 13 cases (5.4%); trigger finger, 12 cases (5.0%); camptodactyly, 11 cases (4.6%); and brachysyndactyly, 9 cases (3.7%). The most frequently acquired injuries were: obstetric traumatic lesions, 26 cases (39.4%); hand trauma sequelae, 18 cases (27.3%); cerebral paralysis sequelae, 7 cases (10.6%); electric shock sequelae, 5 cases (7.6%); and burn sequelae, 4 cases (6.1%). Conclusion: The nosology of hand diseases is similar to that of large series of elective surgery, especially regarding congenital deformities. The frequency of acquired hand lesions seems to be higher than the frequency in international series. The collective mobilization system for hand surgery is important for decreasing the need for this activity in public institutions, and it has been shown to be very efficient. The success of the project may provide support for the Brazilian National Health System to enroll hand surgeons in the on-call system, in emergency units.

Abstract
PURPOSE To develop an alcoholic extract of the inner bark of the Schinus terebinthifolius raddi and to test its impact on autogenously fecal peritonitis in Wistar rats. METHODS The inner bark of the Schinus terebinthifolius raddi was kept for seven days in 70% ethanol alcohol. The total elimination of the solvent was performed in a rotary evaporator under reduced pressure at 55-60°C. Four milliliter of this extract was injected, after 24 h, into the abdominal cavity of six out of eight survival rats that underwent autogenously fecal peritonitis with five milliliter of 10% filtered fecal suspension. They were clinically followed up for 45 days when they were euthanized. The necropsy findings (inventory) of the abdominal and thorax cavities were inspected and the main findings were recorded and photographed. The investigation was approved by the Ethics Committee. RESULTS Two out of six survival rats that were critically ill after 24 h died within the 12 h after the extract injection into the abdominal cavity. Four rats that were also critically ill recovered and gradually became healthy, eating well, regaining weight and moving normally in the cage. At 45 days post severe peritonitis the necropsy findings revealed few signs of residual infection on the abdominal and thorax cavities. There were no bowel adhesions. CONCLUSION The impact of alcoholic extract of the inner bark of the Schinus terebinthifolius raddi was considered very positive and promising as natural local antiseptic against very severe peritonitis in Wistar rats.

Abstract
PURPOSE To evaluate macular and retinal nerve fibre layer (RNFL) measurements in patients with cyanotic congenital heart disease (cCHD) using spectral domain optical coherence tomography (OCT). PATIENTS AND METHODS Thirty patients with cCHD (18 females and 12 males, mean age 10.9 years) and 60 healthy controls (35 females and 25 males, mean age 11.2 years) underwent complete ophthalmologic examination and OCT measurements of macular and peripapillary RNFL thickness. RESULTS Patients with cCHD had significantly thinner measurements in all macular subfields compared with healthy controls (P<0.001). There was no significant difference in peripapillary RNFL thickness between the two groups, with the exception of the upper quadrant, for which thickness measurements were higher in patients with cCHD (P=0.021). CONCLUSIONS Patients with cCHD showed a significant decrease in macular thickness and a thickened superior quadrant RNFL thickness when compared with healthy controls. This may represent the damage caused by the effect of hypoxia.

Abstract
PURPOSE To investigate the morphological aspects of brain and eyes in newborn rats whose mother underwent autogenously fecal peritonitis. METHODS Four pregnant rats that underwent fecal peritonitis, with a 10% fecal suspension in dose of 4 ml per kilogram received two antimicrobial treatments: 1. intraperitoneal moxifloxacin and dexamethazone; and 2. Intravenous meropenem. After head inspection, the brain consistencies and the eyes belonging to all offspring were analyzed. RESULTS The brains of newborn from rats that received 4 ml/kg of 10% suspension of feces showed, significantly smaller and less than the firm consistency of those in the control group. Congenital cataract was observed in 9 (34.6%). No cataract was observed in the 20 newborn rats from the mothers that received the combination of moxifloxacin and dexamethasone. Cataract could be observed in three (13.6%) offspring from mothers that received meropenem. CONCLUSIONS Peritonitis can produce brain damage and congenital cataract in rats. The translation to humans is that intra abdominal infection in pregnant women may be associated with damage in brain and eye structures of their concepts. This can be averting using the adequate early therapeutically approach.

Abstract
PURPOSE To evaluate the treatment outcome of severe peritonitis in rats with increasing age. METHODS Thirty Wistar rats stratified in three groups: group I - six month-old; group II - 12 month-old; and group III - 18 month-old, underwent autogenously fecal peritonitis (6 ml/kg rat), and were treated with intravenous meropenem. The survival animals were followed-up for 45 days. The variables were expressed by their mean and standard error of the mean (SEM). p<0.05 was used for rejecting the null hypothesis. The study was approved by the Ethics Committee. RESULTS There was a significant increase in the mortality and morbidity in elderly rats. Of interest, even among young survival rats presenting with severe residual abscesses both in the abdomen and thorax cavities, they present an almost normal life. CONCLUSIONS The treatment of severe autogenously fecal peritonitis with intravenous meropenem reached reasonable results in rats with six and twelve months of age, even considering residual abscesses on abdomen and thorax cavities. However, the great majority (80%) of elderly rats could not overcome the initial severe infectious challenge, proving that ageing is a very important risk factor for impairing immune response. Thus, sepsis remains a challenging situation, especially in elderly.

Abstract
OBJECTIVE to evaluate the results from and parents' satisfaction with treatment for children with syndactyly who were operated at the "SOS Hand Recife" hospital between 2005 and 2009. METHODS data for assessing the results were gathered from the patients' medical files. The subjective scores, which were ascertained prospectively, were as follows: greater than or equal to 9, good result; between 6 and 8, fair result; less than 6, poor result. The results were analyzed statistically. This study was approved by the institution's ethics committee. RESULTS among the 35 cases, 21 (60%) consisted of simple syndactyly and 14 (40%) were complex; 22 (62.8%) were boys and 13 (37.1%) were girls. The complex cases were predominantly among males. The main complications were infection (11.4%), bleeding (11.4%) and pain (8.6%). There were more complications in the complex cases (42.8%) than in the simple cases (33.3%). The mean scores from the parents' subjective evaluations were as follows: 7.6 for esthetics (7.7 in simple cases and 7.3 in complex cases; 8.2 for function (8.6 in simple cases and 7.6 in complex cases); 8.3 for the parents' general satisfaction level (8.6 in simple cases and 8.0 in complex cases); and 85.7% of the parents would recommend the surgery to others while 14.5% would not. A strong association was observed between the specialist's objective assessment and the scores given by the parents (p < 0.05). CONCLUSION the surgical results from treating syndactyly presented differences between the simple and complex types, even though the parents' esthetic evaluations and satisfaction were similar.

Abstract
PURPOSE To evaluate the treatment outcome of severe peritonitis in rats submitted to permanent bilateral carotid occlusion (PBCO). METHODS Sixteen Wistar rats (mean age of 8.5 months) with PBCO underwent autogenously fecal peritonitis, and were treated with moxifloxacin combined with dexamethasone, and followed-up for 45 days. Ten rats (mean age five months) without PBCO were used as a control group. The variables were expressed by their mean and standard error of the mean (SEM). p<0.05 was used for rejecting the null hypothesis. The study was approved by the Ethics Committee. RESULTS There was a significant increase (p=0.0002) in the mortality and morbidity in older rats that underwent PBCO (study group). However, even among the survival rats presenting with severe residual abscesses both in the abdomen and thorax cavities, they present an almost normal life. CONCLUSIONS The treatment of severe autogenously fecal peritonitis with intraperitoneal moxifloxacin combined with dexamethasone was very effective in young rats without permanent bilateral carotid occlusion. The treatment reached reasonable results in older rats with PBCO, even considering residual abscesses on abdomen and thorax. Older age was the greater risk factor for the outcome of the treatment of severe peritonitis. Sepsis remains a challenging situation, especially in elderly.

Abstract
PURPOSE To compare the profiles and clinical findings of a series of patients with Möbius sequence from Brazil with a series from Italy. METHODS This is a multicenter study, which includes 46 Möbius sequence patients from Brazil and 20 from Italy. Socio-demographic, gestational, and neonatal profile characteristics were collected from interviews with the guardians of the Möbius sequence patients and compared. The Möbius sequence patients were submitted to an ophthalmologic examination and systemic malformations were also evaluated. RESULTS Misoprostol was used in the first trimester of pregnancy by 26 (56.5%) of the mothers of the Möbius sequence patients in the Brazilian series and was not used by any of the Italian mothers. The mean age of the Brazilian Möbius sequence patients was 89.95 ± 7.79 months and the mean age of the Italian patients was 102.6 ± 22.94 months (P=0.6105; Mann-Whitney test). Brazilian mothers had a significantly lower education level (P=0.0002; Fisher's exact test) and Italian mothers had significantly more stable relationships (p=0.0002; Fisher's exact test). The frequency of ocular and systemic abnormalities was similar in both series. CONCLUSION Adverse events during pregnancy varied between both groups. A history of misoprostol use during early pregnancy was present only in Brazilian mothers, who had lower levels of education and less frequent stable marital statuses. Clinical findings were similar between both groups of patients.

Abstract
PURPOSE To evaluate the impact of visual impairment on the quality of life of the elderly population living in the western countryside of Pernambuco State, located in northeast of Brazil. METHODS Five hundred and eighty subjects over 59 years of age were interviewed using the Visual Functioning Questionnaire (VFQ). All subjects underwent complete eye examination. The results of the quantitative parameters were expressed by mean ± SD. The results of categorical parameters were expressed by their frequencies. RESULTS Mean age was of 70 ± 8.1 years. About 86% of the interviewed elderly were illiterate or had incomplete education. The mean complaints were low visual acuity (71.1%) and itching/burning (69.0%). The visual acuity was not normal in 37.4% of the elderly. About 75.0% of the subjects reported to have regular or bad health, and 77.0% reported to have regular or bad vision. The reported quality of life decreased according to the worsening of the visual acuity. CONCLUSION Visual impairment had a negative impact on the quality of life of the elderly population from the western countryside of Pernambuco State.

Abstract
PURPOSE To evaluate the effect of cerebral hypoxia-ischemia on memory and learning survival of rats submitted to permanent bilateral carotid ligation (PBCL). METHODS Twenty-four survivors of PBCL were evaluated after 30 days with regard to memory and learning using a water survival maze. Twenty-three healthy rats were used as control group. The results were expressed by their means and standard error of the mean (SEM). p<0.05 was used for rejecting the null hypothesis. The study was approved by the Ethics Committee for animal investigation. RESULTS The mortality rate for the surgery was 44.4%. The latency time to find the survival platform was higher in rats that underwent PBCL (Normal: 10.24 ± 1.85s - STUDY 25.30 ± 4.69s - Mann - Whitney p=0.0388). Additionally, the type of swimming and the spatial stability of the studied rats on the survival platform were compromised in these animals. CONCLUSION The permanent bilateral carotid ligation induces change in the learning and survival memory.

Abstract
OBJETIVOS: Identificar precocemente a prevalência de aterosclerose, por causa do espessamento do complexo médio-intimal das carótidas comuns e do índice tornozelo-braço. Essas medidas foram relacionadas com os fatores de risco clássicos de aterosclerose e os específicos dos infectados pelo HIV (tempo de doença, tempo de tratamento, tipo de tratamento, tipo de terapia antirretroviral utilizada, CD4 e carga viral). MÉTODOS: Setenta casos infectados com o HIV foram avaliados pela medida automática do complexo médio-intimal nas carótidas e do índice tornozelo-braço. Consideraram-se os fatores de risco clássicos de aterosclerose (idade, sexo, hipertensão arterial sistêmica, tabagismo, hipercolesterolemia, hipertrigliceridemia, obesidade e história familiar de evento cardiovascular), as medidas antropométricas e as variáveis relacionadas ao HIV. O nível de significância assumido foi de 5%. RESULTADOS: O tempo médio de diagnóstico do HIV foi de 104,9 meses e de tratamento foi de 97,9 meses. Quanto ao tipo de tratamento, 47 (67,1%) fizeram uso de inibidor de protease por mais de seis meses e 36 (51,4%) estão em uso atualmente. O índice tornozelo-braço estava aumentado em um único paciente (0,7%) e não se evidenciou espessamento do complexo médio-intimal em nenhum indivíduo. Não existiu associação significante da medida do complexo médio-intimal da carótida comum direita com nenhuma das variáveis analisadas. CONCLUSÕES: Indivíduos jovens, sob o uso de terapia antirretroviral por cinco anos ou mais, não apresentaram espessamento do complexo médio-intimal ou aumento do índice tornozelo-braço. Não houve diferença do espessamento do complexo médio-intimal associada ao tipo de esquema antirretroviral utilizado ou nível de carga viral.

Abstract
RACIONAL: Expressivo contingente de pacientes esquistossomóticos com a forma hepatoesplênica e hipertensão portal apresentam hemorragia causada pela ruptura de varizes esofagogástricas, principal causa de alta morbidade e mortalidade da doença. OBJETIVO: Investigar os efeitos da esplenectomia e ligadura da veia gástrica esquerda sobre fatores de risco de sangramento por varizes esofagogástricas em portadores de esquistossomose mansônica, forma hepatoesplênica, com antecedente de hemorragia digestiva alta. MÉTODO: Estudaram-se, de forma prospectiva, 34 pacientes, com idade entre 1 e 74 anos (média 44,14), sendo 18 (53%) mulheres. Analisaram-se: 1) pressão das varizes do esôfago, aferida pela técnica endoscópica do balão pneumático; 2) tamanho, local, cor e sinais de cor vermelha nas varizes do esôfago; 3) varizes gástricas e gastropatia da hipertensão portal. Realizaram-se avaliações no pré-operatório, no pós-operatório imediato e no sexto mês após a ligadura da veia gástrica esquerda. RESULTADOS: A pressão das varizes do esôfago diminuiu de 22,3+/-2,6 mmHg, antes da operação, para 16,0+/-3,0 mmHg no pós-operatório imediato (p<0,001), caindo para 13,3+/-2,6 mmHg no pós-operatório do sexto mês (p<0,001). A proporção de varizes de grosso calibre, varizes no esôfago superior, varizes de cor azul, varizes com sinais de cor vermelha e de gastropatia da hipertensão portal decresceu de forma significante apenas no sexto mês de pós-operatório. CONCLUSÃO: A ligadura da veia gástrica esquerda, em esquistossomóticos hepatoesplênicos, com antecedente de hemorragia digestiva alta, revelou-se eficaz em diminuir alguns dos principais fatores de risco de hemorragia por varizes esofagogástricas, indicando boa perspectiva no controle definitivo do sangramento.

Abstract
INTRODUCTION Ipsilateral rotational penetrating autokeratoplasty technique may be an alternative to minimize the problem of long waiting lists for transplantation due to keratoconus. PURPOSE To report the visual outcomes in keratoconus patients after ipsilateral rotational penetrating autokeratoplasty technique (IRPAK) associated with a crescent-shape resection of 0.5 mm of the inferior cornea. METHODS According to a prospective, longitudinal, interventional, analytic study, the authors investigated the visual results of 15 patients (18 eyes) with keratoconus, who underwent an ipsilateral rotational penetrating autokeratoplasty, by two coincident trepanations superiorly and with a difference of 0.5 mm inferiorly. After resection of this corneal crescent, a 180° rotation of the corneal disk was performed, which was fixed with 24 sutures diametrically opposed. The patients were followed-up for a period of 24 months. RESULTS Comparing data of the first and second postoperative years to preoperative data, there were: significant improvements in visual acuity, vision lines and spherical equivalent; reduction of topographic astigmatism and maximum and mean corneal curvatures. There was also a decrease in corneal thickness associated to a reduction of corneal endothelial cell count. CONCLUSION There was an improvement of ophthalmologic parameters 6, 12 and 24 months after ipsilateral rotational penetrating autokeratoplasty associated with a crescent-shape resection of 0.5 mm of the inferior cornea, but along the follow-up there was reduction of visual acuity with increased astigmatism.

Abstract
OBJETIVO: Investigar os níveis de IL-10 e IL-13 no soro de portadores da esquistossomose mansônica na forma hepatoesplênica (EHE), avaliando o papel destas citocinas no desenvolvimento da fibrose hepática. MÉTODOS: O estudo foi prospectivo e analítico, desenvolvido no Departamento de Cirurgia da Universidade Federal de Pernambuco, Laboratório de Imunologia Keizo Asami. Foram estudados três grupos: Grupo I - 25 portadores de esquistossomose mansônica na forma hepatoesplênica e não submetidos a tratamento cirúrgico; Grupo II - 30 submetidos à esplenectomia e ligadura da veia gástrica esquerda; Grupo III - 33 indivíduos sem esquistossomose mansônica na forma hepatoesplênica ou qualquer outra doença ou agravo que comprometesse a reserva funcional hepática. As concentrações séricas de IL-10 e IL-13 foram obtidas pelo método ELISA. Considerando-se a natureza não paramétrica, todas as concentrações foram analisadas pelo teste de Kruskal-Wallis. p<0,05 foi usado para rejeição da hipótese de nulidade. RESULTADOS: As médias das concentrações de IL-10, em ng/mL, no soro foram: GI 50,0 ± 59,0; GII 38,0 ± 270; GIII 38,0 ± 20,0. As concentrações de IL-13, em ng/mL, no soro dos pacientes foram respectivamente: GI 41,0 ± 93,0; GII 16,0 ± 17,0; GIII 18,0 ± 34,0. Não se observou diferença significante entre as médias das concentrações de IL-10 e IL-13 entre os grupos de estudo (p>0,05). CONCLUSÃO: As médias das concentrações séricas de IL-10 e IL-13 foram similares nos três grupos estudados, indicando que, possivelmente, estas citocinas no soro não estejam associadas aos diferentes graus de fibrose de Symmers nos pacientes.

Abstract
PURPOSE To evaluate the conjunctival bacterial microbiota and antibiogram profile in the preoperative of antiangiogenic intravitreous injection for age-related macular degeneration, and compare to the preoperative microbiota of patients submitted to cataract surgery. METHODS Cross-sectional, observational, case series study. Two groups were organized: group I (macular degeneration) with 26 eyes from 26 patients (12 men/14 women) with mean age of 69.2 +/- 11.5 years; group II (cataract) with 27 eyes from 27 patients (9 men/18 women) with mean age of 67.6 +/- 7.9 years. The groups were similar regarding age (p=0.538) and gender (p=0.787). The lower conjunctival sac was swabbed and the obtained material was immediately put in a tube filled with liquid culture media BHI ("brain heart infusion"). Samples were processed according to standard laboratory techniques and antibiogram was determined for each bacterial colony. RESULTS Twenty-six bacterial colonies growth in group I, with 2 eyes showing no growth and 30 colonies growth in group II. Gram positive bacteria were more prevalent in both groups: 23/26 colonies (88.4%) in group I and 29/30 colonies (96.7%) in group II, with a Staphylococcus aureus predominance in both groups, with 16 samples (61.5%) and 17 (56.7%), respectively. Coagulase negative Staphylococcus was the second most common identified bacteria, with 19.2% in group I and 20.0% in group II. No differences between the groups reached statistical significance. No statistically significant difference was noted on the antibiotic sensibility between both groups. CONCLUSIONS There was no difference in the distribution of bacteria and antibiogram profile of the conjunctival microbiota in the preoperative of intravitreous injection of antiangiogenic for macular degeneration compared to the preoperative of cataract surgery.

Abstract
PURPOSE: To evaluate retinal manifestations of Schistosomiasis mansoni in its hepatosplenic form in mice. METHODS: It was performed a study with two groups of mice; one of them was infected with 40 cercariae of Schistosoma mansoni. After 120 days of the infection, the eyes underwent a retinal microscopy study. The histology findings were reported. Histomorphometric analysis was also performed, including: thickness measurement of the retinal layer and the number of the ganglion layer cells. RESULTS: In one case a retinal granuloma was found. The analysis of the other histological sections demonstrated normal architecture of the retina. The mean thickness of the retinal layer between the two groups were similar (41.81±6.09µm versus 38.48±8.58µm - p=0.279); as well as the mean number of the ganglion layer cells (20.93±4.88 versus 20.64±4.10 - p=0.864). Disorganization of the retinal layers was not identified and the histomorphometric analysis revealed no significant difference between the two groups. CONCLUSION: The absence of findings in this study does not exclude that hemodynamic and autoregulation changes associated with hepatosplenic schistosomiasis could be correlated to retinal manifestations. It is necessary that other methods with a high parasite infection should be performed.

OBJETIVO: Avaliar a espessura do complexo miointimal (IMT) das carótidas comum e interna, em portadores de esquistossomose hepatoesplênica (EHE) não tratados cirurgicamente, já submetidos a cirurgia para descompressão do sistema porta por esplenectomia e ligadura da veia gástrica esquerda, e comparar com volutários de condições sócio-econômico-ambientais similares, não portadores de esquistossomose. MÉTODOS: Utilizando aparelho de ultra-som Doppler de 7,5MHz foram mensurados os IMT de três grupos de voluntários, de ambos os gêneros, com idades que variaram de 20 a 60 anos, sendo avaliados os IMT máximos, IMT médios, IMT mínimos e seus desvios-padrão, das carótidas comuns e internas e feitas as comparações entre os grupos e suas associações com fatores de risco: idade, hipertensão arterial e tabagismo. RESULTADOS: Não houve diferença significante na média dos IMT, entre os lados direito e esquerdo e nem entre os grupos. Nos pacientes tratados cirurgicamente, assim como nos indivíduos-controle confirmou-se a associação, já conhecida, com os fatores de risco para aterosclerose (idade, hipertensão arterial e tabagismo). Contudo, não se observou este comportamento nos pacientes não operados. CONCLUSÃO: A EHE sem tratamento cirúrgico parece conferir "alguma proteção" contra a aterogênese em seres humanos; todavia, os achados não dão suporte definitivo a esta hipótese.

Abstract
Apesar de a esplenectomia ser eficaz na abordagem terapêutica de pacientes com hemangioma esplênico, esse procedimento é acompanhado de elevada morbidade e até mortalidade, principalmente devido à sepse, quando realizado em crianças e adolescentes com sistema imunitário ainda imaturo. Para prevenir os efeitos adversos da asplenia, propõe-se neste artigo a esplenectomia parcial, com a retirada apenas da região do hemangioma, mantendo o restante do baço e preservando suas importantes funções.

Abstract
PURPOSE To investigate possible ophthalmologic alterations in patients who had severe malnutrition during the first six months of life. METHODS 182 eyes of 91, 2 to 11-year-old, children who had had severe malnutrition during the first six months of life (study group) were analyzed. As a control group 88 children selected according to similar characteristics of age, gender, demographic and economic conditions were included. RESULTS In the study group, a higher frequency of children with visual acuity from 0.3 to 0.1 and less than 0.1 (11.5% versus 0.7% - p< 0.0001) was observed. There was a higher frequency of astigmatism and myopia in the study group. A higher frequency of astigmatism of one diopter or more in the study group (p< 0.0001) was also observed. The fundoscopic alterations were pale optic nerve (2.2%), increased disc cup (4.4%), increased vascular tortuosity (6.6%), alteration of retina color (13.2%) and retinal pigment epithelium cell atrophy (12.0%). CONCLUSIONS The present data support the concept that early malnutrition interferes in the individual's visual health. Further studies are necessary to establish a more precise cause-effect relationship.

Abstract
Surgeons' training requires professionalism, continuing medical education, and appropriate environment to ensure the desirable success. However, generally, this goal is pursued in an inefficient way, based upon intensive training skills founded in the age-old philosophy of "the way I have learned it". There is, usually, a lack of patient outcome evaluation, especially of long-term follow-up of surgical procedures, which in turns provide little evidence of senior surgeons for adequate training junior surgeons. On the other hand, questioning the established knowledge is not stimulated, or even not tolerated by the seniors. It seems like the "truth" is absolute and allows no change for the new knowledge, which would mean no additional progress. There is a need to significantly alter the implementation of new knowledge, if possible based on evidence, to ensure the best medical care for the surgical patient. Experimental surgery, and nowadays bench model surgery, may be useful in minimizing the predictable complications of patients under the surgeon training responsibility, while on learning curve. Surgery based on evidence should be one of the tools for improving patient surgical care, since this important branch of medical activity must rest on two pillars "art and science"; and surgeon in good training needs to be close to both.

Abstract
The repercussions from surgical treatment for controlling portal hypertension and its effects on the gastric vasculature of young patients with mansonic schistosomiasis were investigated by digital image analysis. The study included five patients at the preoperative stage and 27 patients who had undergone surgical intervention at different times in the past: 0-2 years ago, n=4; 2-6 years ago, n=13, and more than 6 years ago, n=10. Endoscopic biopsies were taken from the mucosa of the gastric antrum and body endoscopic mucosa and the samples underwent routine histological tests after embedding in paraffin blocks. Histological thin sections were used for histomorphometric analysis of the following parameters: mean number of vessels per field, and mean diameter and thickness of the vessel walls. The results showed that, between the patients whose operation was not more than two years ago and those whose operation was more than six years ago, there was a significant decrease in the density and diameter of the vessels. These findings give support to the concept that the surgical treatment administered decreases specific histological alterations like hemorrhage and ectasia, over the long term.

Abstract
PURPOSE: To investigate whether the alterations of the diverted colon segment mucosa, evidenced in fecal colitis, would be able to alter Bacterial Translocation (BT). METHODS: Sixty-two Wistar male rats ranging from 220 to 320 grams of weight, were divided in two groups: A (Colostomy) and B (Control), with 31 animals each one. In group A, all animals underwent end colostomy, one stoma, in ascending colon; and in the 70th POD was injected in five rats, by rectal route diverted segment - 2ml of a 0.9% saline solution in animals (A1 subgroup); in eight it was inoculated, by rectal route, 2ml of a solution containing Escherichia coli ATCC 25922 (American Type Culture Collection), in a concentration of 10(8) Colony Forming Unit for milliliters (CFU/ml) - A2 Subgroup; in ten animals the same solution of E. coli was inoculated, in a concentration of 10(11) CFU/ml (A3 Subgroup); and in eight it was collected part of the mucus found in the diverted distal colonic segment for neutral sugars and total proteins dosage (A4 subgroup). The animals from the group B underwent the same procedures of group A, but with differences in the colostomy confection. In rats from subgroups A1, A2, A3, B1, B2, and B3 2ml of blood were aspirated from the heart, and fragments from mesenteric lymphatic nodule, liver, spleen, lung and kidney taken for microbiological analysis, after their death. This analysis consisted of evidencing the presence of E. coli ATCC 25922 CFU. Mann-Whitney and ANOVA Tests were applied as analytic techniques for association of variables. RESULTS: The occurrence of BT was evidenced only in those animals in which inoculated concentration of E. coli ATCC 25922, reached levels of 10(11)CFU/ml, i.e. in Subgroups A3 and B3, although, being significantly greater (80%) in those animals without colostomy (subgroup B3) when compared to the ones with colostomy (20%) from the subgroup A3 (P <0.05). Lung, liver and mesenteric lymphatic nodules were the tissues with larger percentile of bacterial recovery, so much in subgroup A3, as in B3. Blood culture was considered positive in 60% of the animals from subgroup B3 and in 10% of those from subgroup A3 (p <0.05). There was greater concentration of neutral sugars, in subgroup A4 - mean 27.3mg/ml -, than in subgroup B4 - mean 8.4mg/ml - (P <0.05). CONCLUSION: The modifications in the architecture of intestinal mucosa in colitis following fecal diversion can cause alterations in the intestinal barrier, but it does not necessarily lead to an increased frequency of BT.

Abstract
Mansonic schistosomiasis remains a medical-social issue in Northeastern Brazil. In children, surgical treatment includes splenectomy and spleen autoimplantation. This procedure reduces post-splenectomy sepsis. The aim of this study was to analyze the phagocyte rate and the cellular viability of monocytes in patients with hepatosplenic schistosomiasis, who underwent splenectomy and spleen autoimplantation from 1991 to 2001. Of the 22 individuals analyzed, 11 were patients who underwent splenectomy and spleen autoimplantation (Study group) and 11 were healthy individuals from the same region (Control group). Both groups presented similar mean age. No difference was found in the phagocyte rate between the control group (36.1%+/-4.9%) and study group (33.5%+/-5.7%). However, phagocyte viability after stimulation with lipopolysaccharide was higher (94%) in control group, when compared to the study group (65%), p<0.001. It is possible to hypothesize that monocytes from the study group patients presented a reduced response to the microorganism challenge, in the face of a harmful and long-lasting stimulus.

Abstract
OBJETIVO: Investigar os níveis de produção de SOD por monócitos periféricos em pacientes jovens portadores de esquistossomose hepatoesplênica submetidos à esplenectomia, ligadura da veia gástrica esquerda e auto-implante de tecido esplênico. MÉTODO: Quatro grupos foram envolvidos na investigação: G1 - 12 portadores de esquistossomose hepatoesplênica (EHE) sem tratamento; G2 - 13 portadores de EHE que receberam tratamento clínico e se submeteram à operação para descompressão do sistema porta: esplenectomia e ligadura da veia gástrica esquerda (EHE/ELGE); G3 - 19 pacientes jovens similares a G2, mas que receberam também auto-implante de tecido esplênico no omento maior (EHE/ELGE/AI); e G4 - 15 indivíduos sem infecção pelo S. mansoni advindos da mesma área geográfica, apresentando as mesmas condições sócio-econômicas (GC). RESULTADOS: Os indivíduos normais (GC - sem esquistossomose) apresentam níveis de SOD significantemente menores que os portadores de EHE sem tratamento (p<0,01); e aqueles do grupo EHE/ELGE (p<0,05). Os níveis de SOD do grupo EHE/ELGE/AI são estatisticamente similares ao grupo GC (p>0,05). CONCLUSÃO: Os resultados corroboram a hipótese de que o tratamento clínico associado à esplenectomia, ligadura da veia gástrica esquerda e auto-implante de tecido esplênico, em portadores jovens de esquistossomose hepatoesplênica, tendem a manter a resposta imune desses indivíduos.

Abstract
PURPOSE: To measure the levels of NO production by monocytes in patients with the hepatosplenic form of schistosomiasis mansoni who underwent splenectomy, ligature of the left gastric vein and auto implantation of spleen tissue in the major omentum. METHODS: Four groups of volunteers were enrolled in the investigation: G1 - 12 patients with S. mansoni infection in its hepatosplenic form without any kind of treatment (SMH); G2 - 13 SMH patients who underwent medical treatment and portal hypertension decompression splenectomy and ligature of the left gastric vein (SMH/SLGV); G3 - 19 patients similar to the later group, but additionally received auto implantation of spleen morsels in the major omentum (SMH/SLGV/AI); and G4 - 15 individuals with no S. mansoni infection coming from the same geographical area and presenting similar socio economical status (CG). Nitrite production by monocytes was determined by a standard Griess reaction adapted to microplates. The results were presented by mean ± SD for each group. Significant differences in NO production by monocytes were determined by Tukey-Kramer multicomparisons test. Probability values of 0.05 were considered significant. RESULTS: Patients from G1 (SMH) showed lower level of NO production by monocytes (5.28 ± 1.28µmol/ml). Patients from G2 (SMH/SLGV) showed similar results (6.67 ± 0.44µmol/ml - q = 2.681 p > 0.05). Individuals of G4 (CG) showed higher level of NO production by monocytes (8.19 ± 2.74µmol/ml). Patients from G3 (SMH/SGLV/AI) showed similar NO production by PBMC as compared to individuals of G4 (CG) - (7.41 ± 1.65µmol/ml - q = 1.615 p > 0.05). The volunteers from G4 (CG) and G3 (SMH/SLGV/AI) showed significantly greater levels of NO production by monocytes as compared to those from G1 (SMH) - (q = 5.837 p < 0.01, and q = 4.285 p < 0.05). CONCLUSION: Collectively, the results point to a restoration of NO normal production by monocytes in SHM patients who underwent medical and surgical treatments, especially in those who had received auto implantation of spleen tissue in the major omentum after splenectomy and ligature of the left gastric vein. The data gives further support to the hypothesis that this additional procedure is important in the restoration of the immune response of these patients, since NO synthesis by the monocytes correlates with protective immunity against infection; thus, protecting them against overwhelming post splenectomy infection.

Abstract
Hearing loss is a well-known sequelae from meningitis, affecting up to 25% of survivors. However, the principal components of the infectious and inflammatory reaction responsible for the sensorineural hearing loss remain to be identified. The present study aimed to investigate the impact of an augmented neutrophil response on the development of hearing loss and cochlear damage in a model of experimental pneumococcal meningitis in rats. Hearing loss and cochlear damage were assessed by distortion product oto-acoustic emissions (DPOAE), auditory brainstem response (ABR) and histopathology in rats treated with ceftriaxone 28 h after infection. Rats were treated with Granulocyte Colony Stimulating Factor (G-CSF) initiated prior to infection, 28 h after infection or with ceftriaxone only. Rats were followed for 7 days, and assessment of hearing was performed before infection and 24 h and day 8 after infection. Pretreatment with G-CSF increased hearing loss 24 h after infection and on day 8 compared to untreated rats (Mann-Whitney, P = 0.012 and P = 0.013 respectively). The increased sensorineural hearing loss at day 8 was associated with significantly decreased spiral ganglion cell counts (P = 0.0006), increased damage to the organ of Corti (P = 0.007), increased areas of inflammatory infiltrates (P = 0.02) and increased white blood cell (WBC) counts in cerebrospinal fluid on day 8 after infection (P = 0.0084). Initiation of G-CSF 28 h after infection did not significantly affect hearing loss or cochlear pathology compared to controls. In conclusion, the inflammatory host reaction contributes significantly to the development of hearing loss in experimental meningitis.

Abstract
PURPOSE To compare indication criteria, intra- and postoperative complications, visual outcomes and time interval between the first and second eye surgery (phacoemulsification). METHODS Prospective study was done in 96 eyes of patients who underwent bilateral consecutive phacoemulsification surgery, performed by a third-year ophthalmology resident. An established protocol was filled out before, during and after the surgery. The same surgical technique was used. Chi-squared, Mann-Whitney, Kruskal-Wallis, Dunn multiple comparison and Student's t tests were used for statistical analysis. Bicaudal tests were used in all situations. p<0.05 rejected the null hypothesis. RESULTS The indication for the second eye surgery was done earlier and with best correct visual acuity when compared with the first eye (p=0.016). The mean phacoemulsification ultrasound time (US time) of the first eye was significantly higher (p=0.026). There were no statistically significant differences between the two groups in relation to type of cataract, previous intraocular diseases, final visual acuity and mean spherical equivalent. The incidence of intra- and postoperative complications was smaller in the second eye, but was not statistically significant (p=0.07). Time interval between the first and second eye surgery was significantly lower along the trimesters. CONCLUSION The patients underwent the second eye phacoemulsification surgery earlier (with better visual acuity and shorter time interval), had a shorter phacoemulsification time and tendency to be followed by less intra- and postoperative complications.

Abstract
PURPOSE To identify the barriers in the access to treatment of senile cataract and to evaluate the patient's costs in this process. METHODS A survey of 101 patients who would undergo cataract surgery at Altino Ventura Foundation was performed using a questionnaire. The economical and social aspects of the whole process of treatment were evaluated. RESULTS The principal barriers of cataract treatment were: fear of surgery, patient's low income, the need for preoperative examinations and the number of times the patient had to return to the service (3.2 +/- 1.5), as well as the waiting time between the first examination and the surgery (3.2 +/- 2.6 months - Mean +/- SEM). The examination costs varied from 5 to 170 reais (16.6 +/- 2.7 - Mean +/- SEM). DISCUSSION The main reasons for not seeking for cataract treatment, as the fear to undergo surgery and the lack of financial resources had been similar to other Brazilian institutions. The number of times that the patient had to return to the service increased the expenses of the patient and the difficulties faced by him. Altino Ventura Foundation mainly takes care of the poorest population of the State, therefore, the expenses of the patients with transportation and examinations become obstacles to the treatment of cataract. CONCLUSIONS The fear of surgery and the patient's low income and the social level of the institution's users were the principal barriers in the access to cataract treatment in this study. The need for preoperative examinations, sometimes unnecessary, contributes to a lower efficiency of the medical services offered to individuals of low income and social conditions. The surgery carried out at the same day of the cataract diagnosis makes the solution of the illness quickly possible, diminishing the number of times necessary for the patient's return to health service from three or more, to only one.

Abstract
PURPOSE Esophageal variceal sclerotherapy and band ligation seem not to affect the endoscopic findings of Portal Hypertensive Colopathy (PHC) of cirrhotic patients. The aim was to assess the effect of splenectomy and ligature of the left gastric vein on the PHC in carriers of hepatosplenic schistosomiasis mansoni who underwent this surgery when they were between 9 and 18 year-old. METHODS Fourteen patients, mean age of 19.1 +/- 3.1 years, were included in the postoperative group (GI). The follow-up was from 1 to 9 years. The preoperative group (GII) consisted of nine patients, mean age of 14.0 +/- 3.1 years. Full-length colonoscopy was carried out in all patients. Search was made for PHC lesions. RESULTS Telangiectasy (GI 100% vs GII 100%), increased vascularisation (GI 57.1% vs GII 100%), focal and diffuse hyperemia (GI 14.3% vs GII 66.7%), angiodysplasia (GI 7.1% vs GII 33.3%), and rectal varix (GI 0% vs GII 55.6%) were the most frequent findings. It was observed that the patients of this series tended to exhibit fewer hemodynamic manifestations of the PHC after treatment (postoperative versus preoperative - chi2 = 8.155 - p = 0.004). CONCLUSION Splenectomy and ligature of the left gastric vein tend to reduce the abnormal vascular findings of PHC in carriers of hepatosplenic schistosomiasis mansoni.

Abstract
PURPOSE To evaluate the daily cost of antiglaucoma eyedrops and the economic impact related to the minimal wage; to compare the cost of drug association in the single presentation in relation to separate presentations; to analyze the additional percent antiglaucoma drug cost related to standard therapy (generic timolol maleate). METHODS Fifteen eyedrop bottles of each one of the twenty antiglaucoma products were used. The number and mean eyedrop size per bottle of drug were measured and the duration and treatment costs calculated. RESULTS A large variation in the mean daily cost, respectively: R$ 0.077 for generic timolol maleate (cheapest) and R$ 1.910 for Xalacom (most expensive), was observed. It should be noted that the product of minimal economic impact, as related to the minimal wage, was the standard eyedrop therapy with 1.2% to 1.6%, while the association of Xalatan with Timoptol XE showed a variation of 21.7% to 30.0%. The cost of Cosopt and Xalacom was greater than the associations of, respectively: Trusopt + standard eyedrop and Xalatan + standard eyedrop (p<0.001). Xalacom represented an additional cost to standard therapy of 1.698.2% to 1.765.1%. CONCLUSIONS The variation of antiglaucoma eyedrop cost was almost 30 times between the cheapest and the most expensive, which represented an economic monthly impact of 29.1% on the value of the minimal wage. The combined therapy in the separate presentations presented a lower cost than drug association in a single presentation. The use of antiglaucoma drugs represents a high percent additional cost related to standard therapy.

Abstract
A Associação Brasileira de Editores Científicos (ABEC) promoveu, em setembro de 2004, o III Workshop de Editores Científicos em Recife. O enfoque principal foi sobre a forma de divulgação do conhecimento científico: analógico ou digital. Contudo, foram também discutidas as formas de financiamento da produção e divulgação desse conhecimento. A importância maior na produção do conhecimento esteve associada aos institutos de pesquisa, as universidades e as sociedades científicas. Tem sido observada uma tendência ao aumento no gerenciamento eletrônico da editoração e a informatização da divulgação; sobretudo pelo menor custo e maior facilidade; se os recursos humanos das ciências da informação estiverem disponíveis, todavia, a convivência da formatação analógica e digital é esperada por bastante tempo. Foi apresentada a idéia de um sítio eletrônico dos editores, com certificação digital, para que os autores da produção do conhecimento pudessem, com mais facilidade enviar os seus manuscritos. A seleção pelo corpo editorial das revistas desses manuscritos e a participação do corpo editorial na orientação da elaboração dos mesmos foi enfatizada. Essa atitude poderia aumentar a publicação do conhecimento produzido, particularmente daquele advindo dos programas de pós-graduação das universidades. Durante todo o evento ficou evidente a essencialidade da produção do conhecimento como elemento básico de evolução da própria sociedade humana.
