RESUMO

UNLABELLED: Organ transplantation as a substitute for diseased organs in end-stage organ failure has led to a worldwide increase in this treatment modality, but donation has not kept pace with the demand, despite scientific, social, and government efforts. For many years, Hispanic donation in Puerto Rico was meager and lagged behind major centers in North America and Europe. Studies signaled mostly cultural factors in this limited donation. We report a 16-fold increase in organ donation with the development of a formal procurement organization tailored to a local culture. METHODS: The 30-year, 1400-transplant experience of the Puerto Rico Transplant Center was divided in three periods: 1977 through 1893, the latter signaling the approval of a transplant law; 1984 through 1995, signaling the commencement of a formal organ procurement organization; and 1996 through 2006. The subset of 2001 to 2006 was used in an additional calculation against 1984 to 1995. RESULTS: The comparison of the mean deceased donors from 1984 to 1995 with 1998 to 2006 shows a 12-fold increase; and the last 6 years versus 1984 to 1995, a 16.8-fold increase. CONCLUSION: Cultural and educational obstacles in a given country may be overridden by aggressive administrative and educational approaches and strategic planning tailored to local realities, with improvement in organ transplantation.

RESUMO

UNLABELLED: The number of kidney allografts procured from deceased donors has been fairly constant in the past few years, while organs from living donors steadily increase. In our program, existing protocols refused some kidneys which were subsequently accepted and transplanted at other hospitals. Thus, a review of our criteria to accept kidneys became necessary. METHODS: We studied the outcome of all kidneys refused by us but transplanted in other programs between 2002 and 2004. The data analyzed included ID no. donor, transplant center, procurement date, donor age, ischemic times, recipient alive or dead, creatinine level (when it was offered), initial function, hypertension, diabetes mellitus, biopsy, reason why the kidney was not accepted in our program, kidney functioning or lost, and cause of graft failure. The chi-square, Fisher, and t tests were used to analyze our data; P values of <.05 were regarded as significant. RESULTS: Originally 137, we excluded kidneys exported due to mandatory sharing (26 of 137 = 18.97%) and multiorgan placement (10 of 137 = 7.3%). Thus, 101 kidneys were not accepted by us because they did not meet the existing criteria of our program, but were accepted elsewhere. Reasons for nonacceptance were divided into donor quality, donor social history, donor age, donor size/weight, positive serological test, as well as organ preservation time, organ anatomical damage, elevated creatinine, abnormal urinalysis, abnormal biopsy, and decreased urine output. Donor issues were 66 of 101 (65.3%) with a graft loss of 13.6%, and organ issues were 35 of 101 (34.7%) with a graft loss of 66.6%. Donor quality totaled 24 of 66 (36.4%) and donor social history totaled 20 of 66 (30.3%); these were the most common causes for kidney nonacceptance related to donor issues. Reasons related to organ quality included elevated creatinine (15 of 35 = 42.9%; graft loss, 46.6%), and abnormal biopsy (9 of 35 = 25.7%; graft loss, 11.1%) and organ anatomical damage (4 of 35 = 11.4%; graft loss, 75%) (P = .42). Graft loss was more frequent with creatinine levels above 2.4 mg/dL (P < .001, RR gf = 1.5). Long-term fate of these 101 kidneys transplanted elsewhere: 82 (81.2%) were still working while 19 (18.8%) were lost. The causes of graft loss were renal artery thrombosis (42.1%), renal venous thrombosis (26.3%), death for other reasons (15.8%), graft never worked (10.5%), and ESRD (5.7%). The results suggest that the criteria for refusal related to donor issues, including hypertension, diabetes mellitus, donor age and donor size, should be revised owing to the low percentage of graft loss. Other donor issues such as positive serological test and donor social history (drug use, alcoholism) represent a serious potential risk for the health of recipients; for this reason, considering these persons as possible donors is very difficult irrespective of the graft outcome. Kidney refusals related to organ issues (especially elevated creatinine and anatomical damage) due to the very high percentage of graft loss should be considered high risk and probably be excluded. The increase in the demand of kidneys to be transplanted is a very important reason for a continuous and systematic review of donor exclusion criteria in every transplant program. The results presented here have helped us to improve both our outcomes and utilizations based on scientific evidence.

RESUMO

During its first years of existence, the Puerto Rico Transplant Program barely reached 18 to 20 renal transplants per year. A brain death amendment to the law improved the numbers but only to a stable thirty/year. Polls and studies showed that, although people knew about transplantation and expressed willingness to donate, the powerful emotional grief reaction, as well as a peculiar decision-making process, all militated against effective donation. In 1995, LifeLink of Puerto Rico was created as part of the very successful LifeLink Foundation of Tampa, staffed by local professionals. Cadaveric donation increased exponentially by 1227% and in 2004, 22.4 donors per million population were recovered, up from 1.5, one of the steepest growth curves in the United States. As a result, kidney transplantation increased, a cardiac transplant program was inaugurated, a pancreas transplant program has started, and liver will follow. The success is the result of well-trained, culturally sensitive coordinators and requestors; continuous education to the public, hospitals, administrators, neurospecialists, and critical care units; hospital development; implementation of federal law; and a sensitive approach the deceased donor family, and not only to the waiting list patients. The results demonstrate that organizational and educational factors can override cultural obstacles.

RESUMO

Se presenta una especies portadora de un mioblastoma (tumor de células granulares) de la la mama, tumor poco frecuente y de importante diagnóstico diferencial con el cáncer de mama, debido a su gran semejanza clínica e imagenológica. Se trata de una paciente de 66 años de edad con nódulo de 3 centímetros de diámetro en mama derecha, de 6 meses de evolución, de consistencia pétrea, bien definido, no doloroso y con cambios en la piel subyacente, con estudio mamográfico: BI-rads 4. Se realiza biopsia incisional que reporto: Mioblastoma (Tumor de células granulares). En conclusión el mioblastoma representa un reto diagnóstico para el cirujano general debido debido a su semejanza con patología neoplásica. Se debe tener en cuenta al momento de la evaluación de pacientes con nódulos mamarios, en cuyo caso es de suma importancia el estudio anatomopatológico

RESUMO

OBJECTIVE: To analyze the clinical results of a group of young and elderly diabetic patients on ambulatory peritoneal dialysis at a large comprehensive tertiary care community hospital in San Juan, Puerto Rico in relation to rehabilitation characteristics, compliance, complications and survival. DESIGN: The medical records of all patients with a diagnosis of diabetes mellitus trained between June 1985 and June 1992 were reviewed. This group of patients was subdivided according to age, in young (20-50 years) and elderly (50 or over). A comparable number of nondiabetics were selected at random for each of the two age groups. MAIN OUTCOME MEASURES: The patient were studied for age, sex, need of assistance from a partner during dialysis, causes of transfer and hospitalizations, peritonitis, rehabilitation, patients compliance and outcome including mortality. RESULTS: Young diabetics versus non-diabetics: There were 45 patients in the diabetic group (37.8% females) and 57 in the non-diabetic group (54.4% female) with a total observation time of 52.52 patient-months among the diabetics and 82.17 patient-months in the non-diabetic. Mean age of the diabetic patient was 39.9 +/- 8.8 and 36.7 +/- 8.7 for the non-diabetic. Assistance by a partner during the dialysis procedure was needed by 26.7% of the diabetics and by 3.7% of the non-diabetics (p < 0.01). Of the non-diabetics, 91.2% were classified as compliant versus 75.6% of the diabetics (p < 0.05). Peritonitis was the main cause of hospitalizations and of transfers in both groups. The two years patient survival for the diabetic was 81.7% and 100% for the non-diabetic and the two years technique survival was 32.5% for the diabetic and 43.5% for the non-diabetic. Elderly diabetics versus non-diabetics: There were 76 patients in the diabetic group (36.8% female) and 64 in the nondiabetic (43.8% female). The mean age of the diabetic group was 61.3 +/- 6.2 years and 59.3 +/- 7.3 years for the non-diabetic with a total observation time of 81.86 patients-months for the diabetic and 104.58 patient-months for the non-diabetic. Assistance by a partner during dialysis was needed in 63.5% of the diabetics and 19.45% of the non-diabetics (p < 0.01). No statistical difference was found in the rehabilitation or compliance evaluation. Peritonitis stands out again as the main cause of transfer out of the PD modality and main cause of hospitalization in both groups. The two year patient survival for the diabetic was 51.5% and 73.3% for the non-diabetic, while the two years technique survival was 49% for the diabetic and 52.9% for the non-diabetic. CONCLUSIONS: A shortened technique survival, problems of compliance, a high peritonitis rate plus dependency on a partner for dialysis are features of the diabetic group. These findings demonstrate that the diagnosis of diabetes mellitus provides for the development of complications and barriers to the PD modality in both the young and the elderly.

RESUMO

OBJECTIVE: To analyze the clinical results of our patient population on continuous ambulatory peritoneal dialysis (CAPD) and continuous cycling peritoneal dialysis (CCPD) in relation to treatment modality systems, compliance, rehabilitation characteristics, complications, and survivals. DESIGN: The medical records of all patients trained on CAPD or CCPD between 1985 and 1992 were reviewed for the above-mentioned outcome objectives. SETTING: Outpatient CAPD facility affiliated to a tertiary care community hospital. PATIENTS: The total of 305 patients trained during the study period were studied. MAIN OUTCOME MEASURES: The patients were studied for age, sex, primary renal disease, peritoneal dialysis modality, need of assistance from a partner during the dialysis procedure, causes of transfer and hospitalization, peritonitis, rehabilitation, patient compliance, and outcome including mortality. PATIENT POPULATION: 179 (58.7%) males and 126 (41.3%) females, aged 1-80 years (mean 47.2 +/- 15.09) with a total observation time of 15,753 patient-months. The most common diagnosis of the renal disease was diabetic nephropathy (41%). Peritonitis was the main cause of hospitalizations (36.7%) and of transfers (69.5%). Patient survival at one, two, and three years was 87.9%, 76.6%, and 67.0%, respectively. Likewise, technique survival was 65.5%, 45.5%, and 30.6%. Peritonitis rate for CAPD has improved from 1.9 episodes per patient-year to 1.2 episodes per patient-year and an overall rate of 1.5 episodes per patient-year. CONCLUSIONS: The experience in a large Hispanic program shows a good patient survival rate. Although there is a trend to a lower peritonitis rate, this continues to be the main cause of transfer, hospitalization, and one of the main causes of death.
