RESUMO
A model of a fuzzy neuron, one which increases the computational power of the artificial neuron, turning it also into a symbolic processing device, is presented. The model proposes the synapsis to be symbolically and numerically defined, by means of the assignment of tokens to the presynaptic and postsynaptic neurons. The matching or concatenation compatibility between these tokens is used to decide about the possible connections among neurons of a given net. The strength of the compatible synapsis is made dependent on the amount of the available presynaptic and postsynaptic tokens. The symbolic and numeric processing capacity of the new fuzzy neuron is used to build a neural net (JARGON) to disclose the existing knowledge in natural language databases such as medical files, sets of interviews and reports about engineering operations.
RESUMO
The influence of personal, cultural and affective factors and of the characteristics of the neoplastic diseases in the occurrence of pain and pain intensity in 92 patients presenting advanced cancer was evaluated. Pain usually moderate or severe during past week before the interview occurred in 62.0% of the patients. The duration of pain symptomatology lasted 10 months as an average. There was a higher proportion of patients with head and neck tumors in the group with pain than without pain. Cultural misconceptions about cancer pain control and the idea that doctors prescribe excessive amount of analgesics were correlated with higher intensities of pain (p < 0.05). Patients with pain presented higher depression scores than patient without pain (p < 0.05). Higher pain scores were correlated with higher depressive scores (p < 0.05).

There are few epidemiological studies on traumatic brain injury (TBI), and those that allow broad comparative analyses of this problem are even more scarce, due to methodological obstacles. Usually, the studies address head injury (they include the cranial envelopments and content) but are reported as TBI, given the difficulty of mutual exclusion. It is also common for them to be centered at specific severity levels, only for hospitalized victims or according to the external cause, such as traffic accidents. With full respect to these limits, this study had as its objective the estimation of the TBI incidence in patients resident and in-hospital, in the hospital network in the city of São Paulo, Brazil, in 1997, as well as the estimation of TBI-caused mortality amongst external causes, at this same time and locale. Data for the study consisted of Ministério da Saúde data on hospital discharges, analyzed based on Autorizações de Internação Hospitalar (AIH) and obituary data on external causes, contained in the Programa de Aprimoramento das Informações de Mortalidade (PROAIM) data base. It was found that 29 717 patients were hospitalized due to lesions and poisoning; of these 3 635 (12%) had TBI; the hospitalization rate was 0.36/1000 pop.; and hospital mortality was 10%. The mortality coefficient due to external causes was 87.3/100 000 pop. Minimum TBI mortality rate is estimated at a minimum of 26.2 and a maximum of 39.3/100000 pop.

An analysis of the injury patterns presented by inpatients of a government teaching hospital, known as one of the emergency centers of S. Paulo city, Brazil, is given the majority of victims are young, male adults and most of them were later discharged from the hospital. In relation to the injuries the majority of the patients were classified as being of minor injury grade (ISS between 1 and 9) and the most frequent injuries were extremity and pelvic fractures, surface trauma, traumatic brain injury and extremity and pelvic dislocations. Besides extremity and pelvic fractures, the victims who died showed abdominal organ injury and traumatic brain injury and the ISS was over 20. Head injury patients who had a high Glasgow Coma Scale score had a low ISS and vice-versa.

The severity of traumas in hospitalized patients was characterized by means of the Injury Severity Score (ISS) was studied prospectively. One hundred trauma patients hospitalized in a trauma referral health facility located in S. Paulo, Brazil, were analyzed. Of the total number of patients, 68 had blunt trauma and 32 penetrating trauma. As to ISS, it was discovered that 53.0% of the blunt trauma patients had mild trauma (ISS 1-15), 29.4% moderate trauma (ISS 16-24), and 17.6% showed severe trauma (ISS 25); 34.4% of the penetrating trauma patients had mild trauma, 18.7% moderate trauma and 46.9% severe trauma. The mean and standard deviations relating to the ISS of blut and penetrating trauma patients were, respectively, 14.9 +/- 8.1 and 20.8 +/- 11.0; the respective mortality rates were of 11.8% and 12.5%.

OBJECTIVE: The purpose of this study was to discover the differences among victims who had traumatic brain injury due to traffic accidents. METHODS: Medical record of the head injury patients were analyzed according to their classification as traffic accident victims (pedestrian, motorcyclist or passenger and other motor vehicle deriver or passenger), age, gender, admission type (admitted from scene of the injury or from another hospital), duration of hospitalization, type of head injury, types of lesions present in other body segments and mortality. Patient's injury severity was measured by Injury Severity Score and head injury severity was analyzed using the ranking on the Glasgow Coma Scale, recorded by neurosurgeons during their first neuro assessment. All head injured patients admitted to a trauma center in S. Paulo city over a four-month period from March through June 1993, were included in the study. The sample was of 156 victims, with subsets of 80 pedestrians, 26 occupants of motorcycles and 50 occupants of other motor vehicles. RESULTS AND CONCLUSION: The results of this study showed that the mortality rate was higher in the pedestrian subset (25.0%) than among other victims and higher for motorcycle occupants (19.2%) than for motor vehicle victims (8.0%). Statistical differences between the subsets were established when the head injury severity variable was analyzed using the Glasgow Coma Scale. On the other hand, the differences between the three subsets was not statistically significant when the measurement used was the Injury Severity Score. Analyses of other variables showed important differences among subset distributions.

UNLABELLED: The trauma severity assessment and basic life support maneuvers in prehospital setting can represent to the trauma victim the opportunity of survival until his/her can get assistance in the hospital. PURPOSE: To study external cause victims assessed in the prehospital phase by the physiologic index named Trauma Score modificado (TSm). METHODS: Retrospective analyses were made of 1414 victims attended by Sistema de Atendimento Móvel às Urgências (SAMU-RESGATE-SP) in the Municipality of São Paulo during 1991. Data were gathered from prehospital data recording sheets and necropsy records. RESULTS: Prehospital attendance was carried out in 81.31% until 40 minutes. Non-fatal victims (83.96%) had 12 and 11 TSm scores while 53.96% of the fatal victims had 0, 1 and 2 scores. External surface (30.25%) and head/neck (20.98%) were most injured areas and 63.63% fatal victims with Injury Severity Score (ISS) > or = 16 died within first 24 hours. Comparing the fatal victims TSm and ISS scores verified that 81.20% victims with TSm score between 0 and 11 had major trauma (ISS > or = 16). CONCLUSION: Strong trends were also found out in that fatal victims with low TSm scores showed relations to the high ISS scores.

This study was developed in order to compare the use of the ABBREVIATED INJURY SCALE (AIS) and the CONDENSED ABBREVIATED INJURY SCALE (CAIS) as basis to calculate INJURY SEVERITY SCORE (ISS) in head injured patients. The results showed that the ISS value was equivalent in the majority of the patients (58.51%) codified by both scales. Also no statistic differences between the scales were perceived when we compared the severity levels as severe, moderate and minor, 61.38% of the lesions scored by AIS/90 were scored by CAIS/85, too.

Traumatic brain injured (TBI) patients with different trauma severity were analyzed about their recollection concerning the period of hospitalization. The study was carried out in the Head Injury Outpatient Clinic at the Central Institute of the FMUSP Hospital including 45 conscious patients able to sustain an interview. Most patients were male, young adults with the major cause of trauma such as traffic accidents and falls. Most patients (86%) reported unconsciousness state of different time duration in their hospitalization period and were unable to remember anything related to that period. The predominant recollection reported by the patients who never had consciousness decreased after the trauma and that ones who had it but awoke during the hospitalization were: seeing, feeling, hearing, and reacting either to sounds and procedures.

This study is part of a project about ICU's characteristics in São Paulo city. This article describes the continuing education programs for nursing staff. 43 ICUs were analysed and the questionnaire answered by the ICU nurse coordinator was used to collect data. Results showed that 34 (79.1%) of the ICUs have initial program for training each nursing staff category and 18 (41.9%) had regular continuing education program focusing primarily on nursing procedures and routines and the update in pathologies. Continuing education programs are developed primarily by ICU's nurses. 50.2% of the nurses answered that they attended specialisation/extension courses too, in Medical Surgical Nursing or in other areas or in both areas. Due to this result and the development of the ICU's nurses as specialists, some suggestions are presented to improve the continuing education program in these Units.

The goal of this study was to analyse the teaching-learning process of the pupil examination, in two aspects: the pupil diameter (DP), obtained by measurement and photomotor reflex (RFM), by subjective judgement. The sample was composed by 46 students of 4th semester in Nursing Undergraduate Course of University of São Paulo. The study was developed in two phases: the first was at nursing laboratory and the second, at clinical practice. The findings seemed to indicate that the learning was done because there was high level of agreement among students in their observation, development of an ability and a specific knowledge. The major difficulties was at clinical practice.

The present study comprises the results of the use of self-irrigation by 40 colostomized patients, trained by us through a process of systematized training. The effectiveness of the training process can be checked out considering that the most part of the patients have adopted it in its basic features, pointing out a few number of technical difficulties. As to the results of self-irrigation, as a method for controlling the intestinal habit, we can say that 37.50% of the population showed an absence of fecal leakages and 42.50%, sporadic leakages between the irrigations; 27.50% and 35.00%, with absence of gases in the intervals of time and partial use of the collecting pouch, respectively.

The purpose of this study was the analysis of head injury severity based on physiologic and anatomic indexes, shown by hospitalized patients from the Intensive Care Unit. The study was characterized according to patients' age, gender, external cause and remaining time at the Intensive Care Unit, and it was verified that from the total of admitted patients the most of them were young adult males with a remaining time percentage of 6.28 days, Most frequent external cause was traffic motor vehicle accidents (65.72%). The study also considers the lesions and trauma severity according to the Abbreviated Injury Scale/ Injury Severity Score (AIS/ISS), reporting that the lesions were classified as severe lesions non-life threatening (AIS-3) and severe lesions life threatening (AIS-4). It was verified that the body region most affected was head and neck (57.65%). In relation to the trauma severity (ISS), most of the patients reached ISS 16. The study also presents the head injury severity by determining the consciousness level using the Glasgow Coma Scale (GCS); most of the patients showed severe head injury or GCS from 3 to 8. Analysis regarding a possible relation between the GCS and the AIS/ISS was performed to evaluate the head injury severity, considering the fact that the patient was victim of head injury or head injury and other body lesions. No meaning statistical element was observed regarding the relation between the GCS-1 and the AIS from the head region, except when analyzed by groups of severity, or GCS-1 3 to 8 and AIS-head 4 to 5; GCS-1 9 to 12 and AIS-head 2 to 3. Similarly, no meaning statistical relation between the GCS-1 and the ISS, isolated head injury or head injury and other body lesions and the ISS or the GCS. It is expected that this study may contribute with new data for the continuous assistance improvement of patients, with head injury severity either related to other lesions or not, offered both by the Nursing and Health teams.

A prospective longitudinal study of traumatic brain injury (TBI) patients was conducted to identify the recovery pattern 1 year after trauma. Patients with all levels of injury and age between 12 and 60 years were observed. They were analyzed using the eight-point Glasgow Outcome Scale (GOS) as well as their return to productivity in that period. The majority of victims (77.2%) made good recovery, that is (GOS = 0 or 1) and complete recovery or GOS 0 was achieved in 38.6% of then. However at the 1 year mark, 22.8% of the victims showed disabilities. Overall, victims had returned to productivity in that period (83.3%) but 19.4% of them have had changes in their productivity and 16.7% didn't return to your job.).
