Living unrelated donor kidney transplantation between spouses

From November 3, 1975 to November 3, 1990, 874 kidney transplants were performed at our centers. Of these, 675 (77.2%) were from living donors and 199 (22.8%) were from cadaver donors. Five hundred eighty (66.4%) of the living donors were first degree related while 99 (11.3%) were unrelated or second degree related donors, 29 of which were spouses. All donor recipient pairs were ABO-compatible, with the exception of one pair. Donor recipient relations were wife to husband in 25 cases and husband to wife in 4 cases. All were first grafts and started functioning during surgery. In this series, the follow-up for the recipients was 4 to 64 months (mean 33.5 ± 4.5 months). One-year patient survival and graft survival rates were 92.4% and 81.9%, respectively. Two-year patient survival and graft survival rates were 92.4% and 78.2%, respectively. The single ABO-incompatible case is also doing well, 21 months postoperatively. This study demonstrates that the interspouse kidney transplantation may be used when cadaver organ shortage is a problem. While providing the couple with a better quality of life, interspouse kidney transplantation also enables the couple to share the joy of giving and receiving the gift of life from one another.

Resumen En nuestro centro se efectuaron 874 trasplantes renales entre noviembre 3 de 1975 y noviembre 3 de 1990; 675 (77.2%) fueron de donantes vivos y 199 (22.8%) de donantes cadavéricos; 580 (66.4%) de los donantes vivos fueron familiares de primer grado y 99 (11.3%) fueron donantes no relacionados familiarmente o familiares de segundo grado, de los cuales 29 eran cónyuges. Todas las parejas donante-recipiente exhibieron compatibilidad ABO, con excepción de una. La relación donante-recipiente fue esposa a esposo en 25 casos y esposo a esposa en 4 casos. Todos los injertos eran de primera vez y todos comenzaron a funcionar en la mesa de cirugía. El seguimiento osciló entre 4 y 64 meses (33.5 ± 4.5). Las tasas de sobrevida a un año del paciente y del injerto fueron 92.4% y 81.9% respectivamente; las tasas a dos años fueron 92.4% y 78.2% respectivamente. El único caso ABO no compatible también se encuentra bien, a 21 meses en la actualidad. El presente estudio demuestra que el trasplante renal entre esposos puede ser utilizado cuando haya escases de órganos cadavéricos. Al tiempo que permite una mejor calidad de vida, el procedimiento da a la pareja la oportunidad de gozar el hecho de otorgar y de recibir el regalo de la vida entre uno y otro.

Résumé Nous avons effectué 874 transplantations rénales dans nos centres de transplantation entre le 3 Nov, 1975 et le 3 Nov, 1990. Parmi celles-ci, 675 (77.2%) provenaient de donneurs vivants et 199 (22.8%) des reins provenaient de cadavres. Cinq cent quatre vingt des donneurs vivants (66.4%) étaient parents au premier degré alors que 99 (11.3%) étaient parents au 2è degré ou n'étaient pas parents, parmi lesquels 29 étaient des époux. Tous les couples donneur/receveur, sauf un, étaient compatibles dans le système ABO. Le couple donneur/receveur était femme à mari dans 25 cas et mari à femme dans quatre. Il s'agissait dans tous les cas d'une première greffe et qui a commencé à bien fonctionner sur la table d'opération. Dans cette série, le suivi des receveurs allait de 4 à 64 (33.5 ± 4.5) mois. Les taux de survie des malades et des greffes à un an étaient respectivement de 92.4% et 81.9%. Les taux de survie des malades et des greffes à deux ans étaient respectivement de 92.4% et 78.2%. Le seul cas avec incompatabilité ABO va très bien avec un recul de 21 mois. Cette étude montre que la transplantation entre époux est une solution valable en cas de manque de reins. En plus d'améliorer la qualité de survie du receveur et par là même du couple, cette variété de transplantation donne également au couple la possibilité d'avoir la joie de donner et de recevoir un cadeau de vie de leur époux.

     

Reduction in [D-Ala2, NMePhe4, Gly-ol5]enkephalin-induced peripheral antinociception in diabetic rats: the role of the L-arginine/nitric oxide/cyclic guanosine monophosphate pathway

To test our hypothesis that the abnormally small efficacy of mu-opioid agonists in diabetic rats may be due to functional changes in the L-arginine/nitric oxide (NO)/cyclic guanosine monophosphate (cGMP) pathway, we evaluated the effects of N-iminoethyl-L-ornithine, methylene blue, and 3-morpholino-sydnonimine on [D-Ala(2), NMePhe(4), Gly-ol(5)]enkephalin (DAMGO)-induced antinociception in both streptozotocin (STZ)-diabetic and nondiabetic rats. Animals were rendered diabetic by an injection of STZ (60 mg/kg intraperitoneally). Antinociception was evaluated by the formalin test. The mu-opioid receptor agonist DAMGO (1 microg per paw) suppressed the agitation response in the second phase. The antinociceptive effect of DAMGO in STZ-diabetic rats was significantly less than in nondiabetic rats. N-Iminoethyl-L-ornithine (100 microg per paw), an NO synthase inhibitor, or methylene blue (500 microg per paw), a guanylyl cyclase inhibitor, significantly decreased DAMGO-induced antinociception in both diabetic and nondiabetic rats. Furthermore, 3-morpholino-sydnonimine (200 microg per paw), an NO donor, enhanced the antinociceptive effect of DAMGO in nondiabetic rats but did not change in diabetic rats. These results suggest that the peripheral antinociceptive effect of DAMGO may result from activation of the L-arginine/NO/cGMP pathway and dysfunction of this pathway; also, events that are followed by cGMP activation may have contributed to the demonstrated poor antinociceptive response of diabetic rats to mu-opioid agonists. IMPLICATIONS: This is the first study on the role of the nitric oxide (NO)/cyclic guanosine monophosphate pathway on [D-Ala(2), NMePhe(4), Gly-ol(5)]enkephalin (DAMGO)-induced peripheral antinociception and the effect of diabetes on this pathway. The study suggests a possible role of DAMGO as a peripherally-acting analgesic drug.

The effects of aging on the central nervous system steroid profiles and myelin basic protein in rats

The aim of this study was to investigate the effects of aging on the central nervous system steroid and myelin basic protein (MBP) profiles. Forty-seven male Sprague-Dawley rats (newborn, 1, 6, 12 and 24-monthsold) were studied. Tissues were obtained from the cerebellum and parietal, frontal, temporal cortex of the central nervous system of the rats for steroid extraction. The estradiol, progesteron, testosterone and dehydroepiandrosterone (DHEA) levels were measured by Enzyme Linked Immunosorbent Assay (ELISA). The average levels of estradiol (pg/g), progesteron (ng/g), DHEA (ng/g) and testosterone (ng/g) in the brain tissues were respectively 24.29, 4.59, 0.27, 0.92 in the newborn-rats; 4.18 ± 1.10, 1.54 ± 0.30, 0.28 ± 0.01, 0.57 ± 0.10 in the 1 month-old-rats; 11.02 ± 1.10, 2.96 ± 0.30, 0.27 ± 0.01, 0.61 ± 0.10 in the 6 month-old-rats; 15.80 ± 1.10, 4.80 ± 0.30, 0.28 ± 0.10, 0.67 ± 0.10 in the 12 monthold- rats; 20.07 ± 1.10, 4.12 ± 0.30, 0.28 ± 0.01, 0.55±0.10 in the 24 month-old-rats. The myelin basic protein levels were determined by immunohistochemical staining and an elevation was observed in conjunction with the aging process. The results of the study indicate that the alterations in MBP, DHEA, progesterone, testosterone and estrodiol concentrations in the central nervous system of the rats during aging can be considered fundamental for future animal and human studies.     

A scale-development study: Exploration of intensive-care nurses’ attitudes towards futile treatments

The study was conducted to determine the validity and reliability of the tool used to assess nurses’ attitudes towards futility, and to explore intensive-care nurses’ attitudes towards futility. Principal components analysis revealed that 18item scale was made up of four subdimensions that assess Identifying(beliefs), Decision-Making, Ethical Principles and Law, and Dilemma and Responsibilities related to futile treatments. The internal consistency of the scale was in the acceptable range, with a total Cronbach’s alpha value of 0.72. Overall the results of study suggest that scale can be used as a valid and reliable assessment tool to assess nurses’ attitudes towards futility.     

Are Fibrinogen and Complete Blood Count Parameters Predictive in Incarcerated Abdominal Hernia Repair?

Therapeutic delays in cases of external incarcerated hernias typically result in increasing morbidity, mortality, and health expenditures. We investigated the diagnostic role of blood fibrinogen level, white blood count (WBC), mean platelet volume (MPV), and platelet distribution width (PDW) in patients with incarcerated hernia. Two groups, each containing 100 patients, were studied. Group A underwent elective, and group B underwent incarcerated and urgent external hernia repair. We observed high fibrinogen and WBC levels but low MPV and PDW values for patients in group B. Contrary to our expectations, we found lower MPV and PDW values in the complicated group than in the elective group. The morbidity rate and cost burden were higher in group B, and the results were statistically significant. Early operation should be recommended for patients with incarcerated external hernias if their fibrinogen and WBC levels are high.Key words: Incarcerated external hernia, Fibrinogen, Complete blood countExternal strangulated hernia is one of the most common causes of intestinal obstruction especially in the elderly. Delay in treatment may be dangerous.¹ Andrews found that the need of bowel resection rate was 27% and the mortality rate was 21% when diagnosis was delayed more than 48 hours; whereas these rates were 7% and 1.4% when diagnosis was obtained in the first 24 hours.² In addition to increased morbidity and mortality rates, a delay in the treatment of strangulated external hernias is associated with extended hospital stays and an increased need for intensive care, thereby resulting in increased health costs. Of course, clinical signs and symptoms are the most important evidences in diagnosis of incarcerated hernias. In order to make correct diagnosis, we also have powerful weapons such as radiologic imaging methods. However, these clinical and radiologic evidences show complications, especially intestinal perforation due to incarceration. Awareness of probable complications is essential. In this regard, we sometimes need simple methods to alert us. The white blood count (WBC), mean platelet volume (MPV), platelet distribution width (PDW), and blood fibrinogen level have been shown to be valuable predictive parameters for ischemic events in different parts of the body.^3–9 There are probable ischemic tissues and organs in incarcerated hernia sac. So, in this study, we aimed to investigate the effectiveness of these simple blood tests in diagnosis. Generally, there is no problem in diagnosis, but sometimes the delay in treatment results in additional morbidity such as a need for bowel resection.     

Body Mass Index below Obesity Threshold Implies Similar Cardiovascular Risk among Various Polycystic Ovary Syndrome Phenotypes

Objective

The aim of this study was to determine the cardiometabolic risk factors in different polycystic ovary syndrome (PCOS) phenotypes.

Subjects and Methods

This cross-sectional study was performed between 2010 and 2011. Eighty-nine patients with PCOS and 25 age- and weight-matched healthy controls were included in the study. Patients were grouped using the Rotterdam 2003 criteria as: group 1, oligomenorrhea and/or anovulation (ANOV) and hyperandrogenemia (HA) and/or hyperandrogenism (n = 23); group 2, ANOV and polycystic ovaries (PCO; n = 22); group 3, HA and PCO (n = 22); group 4, ANOV, HA and PCO (n = 22); group 5, controls (n = 25). Laboratory blood tests for diagnosis and cardiometabolic risk assessments were performed. Insulin resistance (IR) was calculated in all patients with the homeostasis model assessment of IR (HOMA-IR) formula. An euglycemic hyperinsulinemic clamp test was performed on 5 randomly selected cases in each subgroup, making 25 cases in total, and indicated as the ‘M'' value (mg/kg/min), which is the total body glucose disposal rate.

Results

The mean BMl values of the groups were: group 1, 26.1 ± 5.3; group 2, 27.9 ± 5.2; group 3, 24.3 ± 4.2; group 4, 27.9 ± 7.5; group 5, 24.7 ± 5.2 (p > 0.05). There were no differences in the lipid profile, plasma glucose, HOMA-IR, insulin and M values between the groups (p > 0.05). Phenotypes with oligomenorrhea/anovulation (groups 1, 2 and 4) were more obese than group 3 (p = 0.039).

Conclusions

The cardiometabolic risk profile was similar among the PCOS subgroups. This finding could be attributed to the mean BMl values, which, being below 30, were not within the obesity range. Obesity appeared to be an important determinant of high cardiovascular risk in PCOS.Key Words: Polycystic ovary syndrome, Cardiovascular system, Obesity
