Abstract: introduction: no body knows about the survival and the characteristics of transfusion recipients; however, this information is key to evaluate the cost benefit or effectiveness of the measures introduced for improvement the security of the alogenics transfusions. materials and methods: hospital and blood banks records were collected on all patients at university hospital of valle in cali, colombia , from january through december 1997 (12,567 transfusion episodes) and a random sample (1,189 transfusion episodes). all patients were then matched with the national register of deaths in colombia during a three years follow-up. results: the mean patient age was 42 years and the mean transfusion total was 3.2 units by episode. only 17% of the patients was more than 65 years, 69% under the age of 40 years, and 14.%5 under one year. about 57 % were men. all patients, 38.2% were surgical and 62% treated medically. of the 1054 patients whose survival was investigated, 73.7% were alive after one year, 67.3% after two years and 65.5% after three years. survival was lower in those receiving platelets and larger than 10 units. conclusion: the survival of patients transfused in the university hospital of valle differs of estimates of other studies. this difference has implications for the estimations of cost-effectiveness of blood donors screening for infectious disease.

Materials and methods: Hospital and blood banks records were collected on all patients at University Hospital of Valle in Cali, Colombia, from January through December 1997 (12,567 transfusion episodes) and a random sample (1,189 transfusion episodes). All patients were then matched with the national register of deaths in Colombia during a three years follow-up. Results: The mean patient age was 42 years and the mean transfusion total was 3.2 units by episode. Only 17% of the patients was more than 65 years, 69% under the age of 40 years, and 14.%5 under one year. About 57 % were men. All patients, 38.2% were surgical and 62% treated medically. Of the 1054 patients whose survival was investigated, 73.7% were alive after one year, 67.3% after two years and 65.5% after three years. Survival was lower in those receiving platelets and larger than 10 units. Conclusion: The survival of patients transfused in the University Hospital of Valle differs of estimates of other studies. This difference has implications for the estimations of cost-effectiveness of blood donors screening for infectious disease.

Abstract: An ultrastructural comparison between the nasal cavities of healthy rabbits and those suffering from two forms of spontaneous infection with Pasteurella multocida was undertaken. Twelve commercially produced rabbits of different ages and respiratory health status were divided into four groups: healthy from 0 to 21 days (G1, ); healthy from 23 to 49 days (G2, ); healthy from 51 to 69 days (G3, ); diseased rabbits with septicemia and the rhinitic form of P. multocida infection (G4, ). The main ultrastructural changes observed were a widening of the interepithelial spaces, increased activity and number of goblet cells, the formation of two types of vacuoles in epithelial cells, the degranulation and migration of heterophils between the epithelial cells, and the association of this migration with some of the other changes. No bacteria were observed adhering to the epithelium, and very few were observed free in the mucus. Scant inter-epithelial spaces were found in healthy rabbits, but they were not as large and numerous as those found in diseased animals. We discuss the origin and meaning of these changes but, we focus on the significance of the inter-epithelial spaces and goblet cells for the defense of the upper respiratory airways against the bacterium and its lipopolysaccharide. 1. Introduction P. multocida is commonly associated with different entities of rabbits [1–7]. Clinical signs in rabbits may include rhinitis (snuffles) with purulent nasal discharge, septicemia, pneumonia, otitis media, pyometra, meningitis, and localized abscesses [7–9]. The nasal cavity is considered the natural habitat of P. multocida in different species, including the rabbit [10]; however, neither the normal ultrastructure of this region nor the pathologic changes during natural infection with P. multocida have been described in rabbits. Al-Haddawi et al. [11–13] described the gross, histological, and ultrastructural lesions in this anatomical region of rabbits subjected to different experimental infection protocols with P. multocida A3, P. multocida A3 plus hydrocortisone, and P. multocida serotype D1. The experimental animals were killed 14 and 21 days after inoculation. In general, the gross findings in all three studies were congestion of the nasal mucosa, hemorrhages, and/or mucopurulent exudates. Histologically, these authors observed mild to chronic catarrhal and suppurative rhinitis, with few rabbits displaying ulceration of the mucosal surface. Ultrastructurally, they found severely degenerated epithelial cells that were swollen and had vacuolated cytoplasm; these

Abstract: Background. Gallbladder cancer is a relatively uncommon malignancy in Colombia. To establish the overall rate of gallbladder carcinoma and unexpected gallbladder Study design and methods. We retrospectively evaluate all consecutive cholecystectomies performed in the Fundación Hospital San José de Buga during a 2 year-old period to determine the incidence of carcinoma of the vesicle and to identify retrospectively characteristic common in this particular group of patient. Results. Of the 376 cholecystectomies performed in this hospital during the last two years, the carcinoma of gallbladder was diagnosed in six patients alone in one of them was suspected before the surgery. In accordance with the literature, the occurrence in women (83.3%) was higher than in men (16.7%). The mean age was 58.5 years (range 41±71). Its presentation is similar to that of lithic disease of the gallbladder. The most common symptom is was abdominal pain; the majority (66.7%) had cholelithiasis, and the pathological reports confirm the diagnosis adenocarcinoma in all the six patients. Conclusions. The overall incidence of unsuspected gallbladder carcinoma in our series was 1.6%. We could not find common characteristic for this particular group of patient when compared to patients with no-malignant pathology. Gallbladder cancer was undiagnosed for clinical physician, radiologist, surgeon and pathologist for examination macroscopic specimens.

Colombia Médica , 2004,
Abstract: Context: Autopsy rates have declined all over the world recently. Clinical autopsy is considered to be an essential element for medical auditing and teaching and a useful tool for the evaluation of accuracy of the clinical diagnoses. Objetive: We describe the concordance between clinical diagnoses and autopsy findings in a tertiary care center. Materials and methods: We compared the diagnosis recorded on medical charts with reports of 100 autopsies performed between 1970 and 1975, and in 100 autopsies performed between 1990 and 1995 in the department of pathology of a terciary care hospital. The autopsy diagnoses were used as the gold standard . Results: The higher sensivity for diagnosis was observed for neoplasic disease in both period and for hemodinamics disorders, thrombosis and shock in 1970. The clinical diagnosis of the basic cause of death was confirmed at autopsy in 73% and 64% of cases in period 1970 and 1990 respectively. The percent confirmation fell when the immediate terminal cause of death was considered, and in 36.5% of cases, the terminal cause was only diagnosed at autopsy. Of 200 adults patients, 62 (31%) had an infectious disease at autopsy. In 25 (40.3%) of 62 patients, the infectious disease diagnoses were unknown clinically. There are substantial discrepancies between clinical and autopsy diagnoses of infectious disease. The bronchopneumonia is the infectious disease most often missed clinically (24.5%) of the cases, similar in both periods. The discrepancies between clinical and autopsy diagnosis were even larger for secondary diagnoses: 63% of them were not suspected upon clinical diagnosis. The most frequently omitted diagnosis was bronchopneumonia. Iatrogenic injuries were very frequent, and approximately 28% of them were not described in clinical reports. Conclusions: Our results suggest that highly sensitive and specific diagnostic tests are necessary but cannot substitute the clinical practice for the elaboration of correct diagnoses. The possibility that a given autopsy will reveal an important unsuspected diagnosis not has decreased over time, remains sufficiently high encouraging ongoing use of the autopsy.
