Fatores litogênicos em pacientes com litíase urinária de Fortaleza, Ceará

Lithiasis is considered a public health issue due to its high prevalence and rates of recurrence. Objective: To identify risk factors for lithiasis in kidney stone patients from Fortaleza, Brazil. In the first stage of the study, the medical records of 197 patients with urinary lithiasis covering the period 1996 2006 were analyzed with regard to clinical and metabolic data. In the second stage, 340 kidney stones were submitted to morphological examination under 10x magnification. According to the external morphology and the cut surface, the stones were classified as pure or mixed, and major and minor components were identified. In addition, the stone fragments of 25 patients treated with lithotripsy were submitted to morphological analysis. In the third stage, a subsample of 50 stones was used in a double-blind comparison of morphological and chemical findings. Results were expressed as concordant, partly concordant (discordant for minor components) or discordant (discordant for major components). The average age of first symptoms was 35.8±13.3 years, with no significant difference between the genders. The male/female ratio was 1:1.7. Recurrence was reported in 53.3% of cases. The main metabolic changes observed were hypernatriuria (80.7%), hypercalciuria (48.7%), low urine volume (43.7%), hyperoxaluria (30.5%) and hyperuricosuria (17.3%). Pure stones represented 34.7% of the total sample of 340 stones. The most common route of elimination was spontaneous for pure stones (49.1%) and surgical for mixed stones (50.5%). Pure stones consisted most frequently of calcium oxalate (OxCa) (59.3%) and uric acid (UA) (23.7%), the former prevalent in women, the latter prevalent in men. The most frequently observed component in mixed stones was OxCa (67.1%), followed by carbapatite (11.2%) and struvite (7.9%). The main components were OxCa and UA for men, and carbapatite and struvite for women. Nearly half (48%) the 25 analyzed fragments were pure, consisting of calcium oxalate dihydrate (COD) (56%), calcium oxalate monohydrate (COM) (48%), phosphate (32%) and UA (20%). Four patients (16%) had infectious stones. In the chemical analysis of the subsample of 50 stones, the most 64 frequently observed major components were calcium (70%), oxalate (66%), ammonium (56%), urate (28%) and carbonate (24%). In the morphological analysis, the main components were calcium and magnesium phosphate (32%), COM (24%), UA (20%), COD (18%) and cystine (6%). Morphological and chemical findings were totally concordant for 38% of the stones, partly concordant in 52% and discordant in 10%. Conclusion: The risk factors for lithiasis in kidney stone patients from Fortaleza (Brazil) were hyperoxaluria, hypercalciuria with or without hypernatriuria, hyperuricosuria and low urine volume

Infecção hospitalar associada ao uso de cateter venoso central e a quebra de protocolos pelos profissionais de saúde na UTI de um hospital universitário em Natal/RN

This is a study descriptive cross-sectional and quantitative approaches, which aimed to analyze the association between hospital infection rate for insertion, maintenance of central venous catheter and the breakdown of protocols (rules and routines) by health professionals assisting patients in the ICU of a university hospital in Natal / RN. The process of data collection was through observation with structured form, refers to medical records and structured questionnaires with health professionals. The results were organized, tabulated, categorized and analyzed using SPSS 14.0. The characterization of the subjects was performed using descriptive and inferential statistics, taking into account the nature of the variables, with analysis of variance (ANOVA) and Spearman correlation test, it was a discussion of the information obtained, considering the mean, standard deviation, coefficient of variance and standard error. The variables that showed a higher level of correlation were treated with the application of significance tests. As the results, 71% of participants were female and 29% male, age ranged from 18 to 85 years (52.6 ± 22.5). The insertion, there was a variation from 0 to 5 errors (1.2 ± 1.4), during maintenance, the average was 2.3 ± 0.9 errors, ranging from 0 to 4. During the insertion and maintenance of CVC, patients who had been an infection ranging from 2 to 9 mistakes (4.2 ± 1.7), since those who did not show the variation goes from 0 to 5 errors (2, 8 ± 1.5). The correlation coefficient between the risk of infection throughout the process and the risk of infection at the insertion showed strong and significant (r = 0.845 p = 0.000) and in relation to risk of infection in maintenance was moderate and significant (r = 0.551 p = 0.001). The mistakes made by professionals in the procedures for insertion and maintenance of the catheter, associated with other conditions, shown as a risk factor for the of IH

Úlcera de pressão em pacientes internados em um hospital universitário em Natal/RN: condições predisponentes e fatores de risco

The pressure ulcers (PU), also known as decubitus ulcers, are defined as injuries caused by the constant pressure exerted on a particular point of the body, causing impairment of blood supply with a decrease or interruption of tissue irrigation, causing occlusion of blood vessels and capillaries, ischemia and cell death. This is a descriptive study with longitudinal design, and panel type, with quantitative approach that aimed to examine the association between predisposing conditions (PC), intrinsic factors (IF) and extrinsic factors (EF) with the occurrence of PU, in hospitalized patients in the Intensive Care Unit (ICU), pain clinical, surgical clinical and neurology wards of a university hospital. The study population was composed of all patients who were restricted to bed during the period from December 2007 to February 2008. The study was approved by the Ethics Committee of HUOL / UFRN (No 135/07). The data-collection took place through a structured formulary of observation, data from medical records and physical examination of patients skins. The results were organized in SPSS 15.0 software, tabulated, categorized and analyzed by descriptive and inferential statistics. Of the 30 patients studied, 43.3% had been hospitalized in the pain clinical and surgical clinic wards, 20.0% in the ICU, 20.0% in the ICU / ward and 16.7% in neurology, being the length of hospitalization in those units of 7 to 18 days (63.3%) and from 19 to 30 days (36.7%), predominantly female and aged ≥ 60 years (60.0%). 19 PU were diagnosed in 43.3% of patients monitored, being 38.5% with one PU between 7 to 18 days and 46.2% with two or more between 19 to 30 days of hospitalization, showing significant relationship (ρ-value = 0029) between length of hospital stay and the number of PU. Was found an association of 35.7% of the PC (cardio-respiratory, hematological, metabolic and psychogenic), IF (age group, oedema, skin changes in humidity and change of body temperature) and EF (type of mattress and strength of body pressure) for all patients studied, statistically significant (ρ-value = 0001), between the average scores in patients with and without PU, with reason chance to 12.0 for the development of PU and there was moderate correlation ( r = 0618) in the presence of this association. Results show the influence of the multiplicity of factors and conditions on the occurrence of PU, which brings us to reflect on the assistance focused on prevention and reduction of these injuries which will encourage the reduction of hospitalization length, physical and psychological suffering, and the possibility of improving the clinical condition of the patient.

Recidiva de câncer labial em pacientes atendidos no hospital DR. Luiz Antônio (Natal-RN) entre 1997-2004

Introduction: Cancer of the lip is very common in tropical countries, being noticeable the squamous cell carcinoma as the main histological type. Objective: Evaluate the socialdemographic profile, habits, occupation, clinical characteristics of the cancer lesions and the aftermath of treatment of the patients treated on the Luiz Antônio Hospital (Natal-RN). Design: Retrospective cohort. Methods: We analyzed 181 medical records of patients from the Luiz Antônio Cancer Hospital (Natal-RN) in the period between 1997 and 2004. The statistic evaluation of time between the diagnosis and the relapse or the cure of the patient were done through the Kaplan-Meier method and the comparison of survivor functions were done through the Log-rank test. Later, was estimated the proportional risk model of Cox. Results: The study population were composed by 69,1% males, 95,2% unlettered, the mean age of 66,5 years, 89,0% of smokers and 64,1% had an occupation involving sun exposure. In regard to the clinical characteristics, most lesions were in the lower lip (77,9%), the size of the tumor was smaller than 2 cm (51,8%), 92,6% had localized lesions. Were verified 16,3% of local relapse and 13% of regional. Almost the totally of the cases corresponded to squamous cell carcinoma (97,2%). We observed smaller accumulated probability of not occurrence of local relapse when the base and borders were free of lesions (p=0,041), as well as a smaller probability of regional relapse when the sort of treatment was surgery, associated with other therapeutics modalities (p=0,001). The patients with advanced pathologic stage (p=0,016), treated with surgery associated with other therapeutics modalities (p=0,001) and diameter above 4cm (p=0,019) presented a bigger possibility of any kind of relapse. The multivariable analysis pointed the complex treatments (surgery plus other therapeutics modalities) as a predictor variable for occurrence of new local lesions (p=0,001) and total (p=0,046), besides the age above 70 years to the regional relapse (p=0,050). Conclusion: Cancer of the lip occur in the lower lip, in males, smokers and individuals exposed to Sun light. The relapse was frequent, even being localized and without great consequences to the patient s health. The probability of relapse is related to the size and borders of the lesion and to the histological exam, as well as to the patient s age and complexity of the treatment chosen

Avaliação de alterações orais em pacientes submetidos a transplante de medula óssea

Bone marrow transplantation (BMT) is currently the best therapeutic option for patients with hematologic diseases, solid tumors or autoimmune disorders. It is characterized by intravenous infusion of hematopoietic stem cells in order to restore marrow function. However, this procedure requires concomitant immunosuppression treatment, which favors the development of certain complications, often manifested in the oral cavity. This study aimed to evaluate the incidence of oral changes in patients undergoing BMT and to correlate these results with clinical aspects related to the patients and the transplants performed. This is a prevalence study, with cross-sectional design, carried out in a BMT service at the Institute of Onco-Hematology of Natal (ION) and Natal Hospital Center. Data collection was based on questionnaires, clinical examination of the oral cavity and consultation in the medical records. The sample consisted of 51 patients undergoing BMT. After the analysis, was found a general status with good health conditions and presence of oral changes in about half of patients who composed the sample. The manifestations observed were, in decreasing order of frequency: mucositis; gingival alteration and thrombocytopenic purpura; mucosal pigmentation; lichenoid reaction and candidiasis. The oral changes were observed more frequently in cases of allogeneic TMO, in different periods post-transplant, without significant differences related to the source of cells. It was found statistically significant association between the presence of graft-versus-host disease (GVHD) and oral changes (p < 0,001). Therefore, it is concluded that there is a relatively high incidence of changes in oral cavity of patients receiving bone marrow transplantation, a fact which confirms the need to consider this site for examination, diagnosis, treatment and prognosis of possible complications of BMT

Desempenho auditivo ao longo do tempo e satisfação dos usuários de implante coclear com perda auditiva pós-lingual

Most cochlear implant (CI) users, who suffer from post lingual hearing loss, are able to perceive sounds and comprehend speech after the implant. The prediction of maximal benefit over time, with the use of CI, can be useful for counseling patients about their expectations in using the new device. The measurement of satisfaction should be of primary interest in medical intervention, as the results may be used for intervention feedback. The purpose of this study is to analyze auditory performance of CI over time, as well as to evaluate users‟ satisfaction. Therefore two types of study designs were employed: a) retrospective cohort study with the analysis of medical records from 59 subjects about auditory performance before and after surgery. Results were submitted to the Kaplan -Meier estimator of cumulative probability and compared to prognostic factors of auditory performance using the logrank test. b) A sectional study design was conducted to evaluate the satisfaction of 51 subjects. The instrument consists of two specific questionnaires: Satisfaction with Amplification in Daily Life SADL and International Outcome Inventory Cochlear Implant IOI- CI. Results show statistical significant differences (p<0,001) in auditory performance before and after CI. The majority obtained satisfactory results of CI use during the first six months. Logrank tests does not indicate significant correlation between the analyzed covariates and the time in which adequate speech perception occurs. SADL e IOI-CI questionnaires indicate that most of the CI users are satisfied with their devices. The SADL detected a 27, 5% insatisfaction amongst CI users in relation to services and costs involved with the CI. The results of the IOI show 4% of insatisfaction with the use of CI and the social environment. In conclusion CI is capable to rehabilitate social auditory function in a short period of time and CI users demonstrate satisfaction with auditory, social and psychological gain offered through CI device

Weight and neuro-psycho-motor development in children discharged from neonatal intensive care unit

Background: Low birth weight affects child growth and development, requiring the intensive use of health services. There are conversely proportional associations between prematurity and academic performance around the world. In this study we evaluated factors involved in weight and neuropsychomotor profile in one and two years old discharged from Intensive Care Units (ICU).Methods/Design: We investigated 203 children from the ICU who were followed for 24 +/- 4 months. The research was conducted by collecting data from medical records of patients in a Follow-up program. We investigated the following variables: inadequate weight at one year old; inadequate weight at two years old and a severe neurological disorder at two years old.Results: We observed increase of almost 20% in the proportion of children which weighted between the 10th and 90th percentiles and decrease of around 40% of children below the 15th percentile, from one to two years old. In almost 60% of the cases neuropsychomotor development was normal at 2 years old, less than 15% of children presented abnormal development. Variables that remained influential for clinical outcome at 1 and 2 years old were related to birth weight and gestational age, except for hypoglycemia. Neurological examination was the most influential variable for severe neurological disturbance.Conclusion: Hypoglycemia was considered a new fact to explain inadequate weight. The results, new in Brazil and difficult in terms of comparison, could be used to identify risk factors and for a better approach of newborn discharged from ICUs.

Programa de cessação de tabagismo como ferramenta para o diagnóstico precoce de doença pulmonar obstrutiva crônica

OBJETIVO: A doença pulmonar obstrutiva crônica (DPOC) é subdiagnosticada e subtratada, o que resulta em subestimação do impacto da doença. O objetivo deste estudo foi avaliar se a inclusão da espirometria na avaliação dos fumantes que ingressam em programas de cessação do tabagismo contribui para o diagnóstico precoce da DPOC. MÉTODOS: Análise retrospectiva de dados médicos de 158 fumantes atendidos no programa cessação de tabagismo (Faculdade de Medicina de Botucatu, São Paulo, Brasil), de janeiro 2003 a novembro 2005. Todos os indivíduos tinham mais de 40 anos (idade média: 55 ± 8,5 anos), sendo 99 (62,6%) do sexo feminino. Foram analisados os dados clínicos, os diagnósticos médicos prévios e os resultados da espirometria. RESULTADOS: Dos 158 fumantes avaliados, 57 (36,1%) indivíduos preenchiam os critérios diagnósticos para DPOC e 14 (8,9%) foram considerados em risco para o desenvolvimento da doença. Dos 57 que preenchiam os critérios diagnósticos para DPOC, 39 (68,4%) foram diagnósticos novos e 18 (31,6%) foram confirmação de diagnóstico prévio da doença. Entre os 18 com diagnóstico anterior, 10 (56%) tinham doença leve/moderada e 8 (44%) doença grave. Sete pacientes com diagnóstico anterior de DPOC apresentaram resultados de função de pulmonar não compatíveis com os critérios diagnósticos da doença. Entre os 39 novos diagnósticos, 38 (97,4%) eram de doença leve/moderada e apenas 1 (2,6%) tinha DPOC grave CONCLUSÃO: A inclusão da espirometria na avaliação inicial dos fumantes admitidos em programa de cessação de tabagismo pode ser uma ferramenta útil para o diagnóstico precoce da DPOC.

Influence of educational level on myocardial hypertrophy of hemodialysis patients

Introduction: Chronic renal disease is associated with a high cardiovascular risk. Data from the general population associate cardiovascular diseases with low educational level, but no study has evaluated this association in patients on hemodialysis. Objective: This study aimed at evaluating the association between educational level, hypertension, and left ventricular hypertrophy in patients on chronic hemodialysis. Methods: A standard socioeconomic questionnaire was applied to 79 hemodialysis patients at the Hospital das Clínicas of Faculdade de Medicina de Botucatu, state of São Paulo. Clinical, laboratory and echocardiographic data were obtained from medical records. The patients were divided into two groups according to the median educational level, as follows: G1, patients with three or less years of schooling; G2, patients with more than three years of schooling. Results: Blood pressure, interdialytic weight gain, and variables statistically different in the two groups (p < 0.2) underwent multiple analysis. Independent associations were stated with p < 0.05 in multiple analysis. The mean age of patients was 57 ± 12.8 years, 46 were males (57%), and 53 white (67%). The variables selected for multiple analysis were: age (p = 0.004); educational level (p < 0.0001); body mass index (p = 0.124); left ventricular diameter (p = 0.048); and left ventricular mass index (p = 0.006). Antihypertensive drugs were similar in both groups. Systolic blood pressure (p = 0.006) and years of schooling (p = 0.047) had a significant and independent correlation with left ventricular mass index. Conclusion: In hemodialysis patients, left ventricular mass associated not only with blood pressure but also with educational level.

Avaliação da utilização de biópsia transbrônquica em pacientes com suspeita clínica de doença pulmonar intersticial

OBJETIVO: Estudar os padrões clínicos, radiológicos e histopatológicos da biópsia transbrônquica (BTB) utilizados para a confirmação diagnóstica em pacientes com suspeita clinica de doença pulmonar intersticial (DPI) atendidos em um hospital universitário de nível terciário. MÉTODOS: Os prontuários, laudos radiológicos e de biópsias transbrônquicas de todos os pacientes com suspeita de DPI submetidos a BTB entre janeiro de 1999 e dezembro de 2006 no Hospital das Clínicas de Botucatu, localizado na cidade de Botucatu (SP), foram revisados. RESULTADOS: Foram incluídos no estudo 56 pacientes. Desses, 11 (19,6%) apresentaram o diagnóstico definitivo de fibrose pulmonar idiopática (FPI), que foi significativamente maior nos casos nos quais DPI era uma possibilidade diagnóstica em comparação com aqueles nos quais DPI era a principal suspeita (p = 0,011), demonstrando a contribuição da BTB para a definição diagnóstica dessas doenças. O exame histopatológico dessas biópsias revelou que 27,3% dos pacientes com FPI apresentavam o padrão de pneumonia organizante, o que pode sugerir doença mais avançada. O padrão histológico indeterminado foi o mais frequente, refletindo a característica periférica da FPI. Entretanto, o padrão fibrose apresentou alta especificidade e alto valor preditivo negativo. Para os padrões sugestivos de FPI em TC, a curva ROC indicou que a melhor relação entre sensibilidade e especificidade ocorreu com a presença de cinco alterações radiológicas, sendo o aspecto de favo de mel fortemente sugestivo de FPI (p = 0,01). CONCLUSÕES: Nas DPIs, a TC de tórax deve ser sempre realizada e a BTB usada em situações individualizadas, conforme a suspeita e distribuição das lesões.

Pulmonary tuberculosis: Hematology, serum biochemistry and the relation with the disease duration

The aim of the present study was to analyze the relationship between hematological and biochemical parameters and tuberculosis process activity time according to clinical complaint duration. It was a retrospective study analyzing medical records from 80 pulmonary tuberculosis patients at Botucatu Medical School University Hospital ( Botucatu, São Paulo State, Brazil), who were divided into 2 groups according to clinical complaint duration: Group 1 ( G1) - up to three months; Group 2 ( G2) - over three months. Parameters included: age, gender, bacilloscopy, erythrocyte sedimentation rate ( ESR), platelet count, alpha1-globulin, alpha2-globulin, gamma globulin, mucoprotein, alpha1-acid glycoprotein values, and the presence of risk factors such as smoking, alcoholism, drug addiction, sexual promiscuity, contact with tuberculosis carriers, and previous treatment. Groups were compared by calculating t and p, and Chi-square (X-2) and p. Comparisons revealed a tendency towards smoking with a higher frequency of smokers in G1 ( 0.05< p< 0.10). G1 also tended to present greater platelet values than G2 ( 0.05< p< 0.10) and presented significantly higher ESR values than G2 ( p< 0.05). Other factors did not show any significantly different behavior between groups ( p> 0.05). A correlation was found between ESR, platelet count, smoking and less than three months clinical duration.

Caracterização epidemiológica e demográfica de homens com câncer de próstata

O estudo pretende identificar características demográficas e epidemiológicas em homens com câncer de próstata, atendidos no Hospital das Clínicas da Faculdade de Medicina de Botucatu/UNESP, entre 01/01/2000 e 31/01/2003. Foram colhidos dados em 78 de 94 prontuários, observando-se escolaridade, uso de tabaco, estado civil, idade, diagnóstico e sintomatologia. Utilizou-se metodologia quantitativa associada à estatística descritiva. Foram encontrados 50% com 1º grau incompleto, 27,39% não tabagistas, 87% casados, 43% entre 64 e 73 anos. Observou-se que 27,58% foram diagnosticados em 2000, sendo 63,20% aposentados e 20,70% com sintoma de jato urinário fraco. Apenas 20% tinham realizado exames preventivos e, desses, 77,90% possuíam 1º grau incompleto. O estudo foi feito nesse hospital por ser considerado de referência terciária da Direção Regional de Saúde de Botucatu -DIR XI¹. da amostra, 80% procuraram o serviço apresentando sintomas, o que leva a crer que ainda haja falta de orientação da população quanto ao câncer de próstata, principalmente quanto à incidência e prevalência relacionadas à idade, como fator de risco. O estudo evidencia subsídios para um melhor direcionamento da assistência a esses pacientes, permitindo um diagnóstico precoce e conseqüente possibilidade de cura, além da melhora na qualidade de vida.

Geographical Distribution and Demographic Characteristics of Gestational Trophoblastic Disease

OBJECTIVE: To outline the geographical distribution pattern of gestational trophoblastic disease (GTD) in a referral center in Bahia, Brazil, and determine the demographics of the disease.STUDY DESIGN: We conducted a study of data retrieved from medical records of 140 GTD patients referred to our Trophoblastic Diseases Center in 2002-2007, assessing geographical distribution across health care districts, demographics, referral sources, and previous pregnancy status.RESULTS: The most common GTD types were hydatidiform mole (106, 75.7%), invasive mole (32, 22.9%), choriocarcinoma (1, 0.7%), and placental site trophoblastic tumor (1, 0.7%). GTD incidence was 8.5 in 1,000 deliveries. Most patients originated from the coastal region (East district), which includes the state capital (77.9%). The 20-34 age group predominated (65%). Education level (67.9% attended elementary school only) and employment rate (42.9%) were low. Secondary hospitals were the principal source of referral (84.3%), followed by self-referrals (15.7%). Regarding previous pregnancy status, 42.1% (n = 59) had had term pregnancy, 39.3% (n = 55) no pregnancy, 15% (n = 21) miscarriage, and 0.7% (n = 1) ectopic pregnancy; 4 patients (2.9%) had previous hydatidiform mole.CONCLUSION: GTD predominated in the peak fertility age group and among patients of unfavorable sociodemographic status.
