Abstract
Radioiodine therapy is the safest, simplest, least expensive and most effective method for treatment of Graves' disease. Due to difficulties in previous methods for dose determination, fixed dose method of 1-131 is now considered the best practical method for 1-131 therapy in Graves' disease, but there is no consensus on the dose. We compared two routinely recommended fixed doses of 5 and 10 mCi for this purpose.
Materials and Methods In this clinical trial, 59 patients with Graves' disease referred for radioiodine therapy were randomized into two groups, one group was treated with 5 mCi of 1-131 and the other with 10 mCi. All patients were followed for two years, with 6-month intervals.
Results: Totally, among 59 patients treated with 1-131, 20 (33.9%) patients became euthyroid and 19(32.2%) became hypothyroid, while failed therapy (no response or relapse) was noticed in 20 patients (33.9%). In the group treated by 5 mCi (33 patients), 10(30.3%) were euthyroid, 6(18.2%) were hypothyroid (overall cure of ^8.5%), while 17(51.5%) remained hyperthyroid by the end of the follow-up period. From the 26 patients treated with 10 mCi, the euthyroid and hypothyroid states were observed in 10(38.5%) and 13(50%)patients, respectively (overall cure rate of 88.5%), and hyperthyroid state in 3(11.5%). No relationship was noted between the outcome and age, sex, size of the thyroid gland and thyroid uptake, but the relationship between the disease outcome and the amount of administered radioiodine was significant (P<0.003). Although the incidence rate of early hypothyroidism (by the end of 2 years) in the group treated with 5 mCi is less than those treated with 10 mCi, the incidence of failed therapy is higher in the former group. In addition, it is known that long-term hypothyroidism prevalence is not significantly different by using different doses of I-131. On the other hand, if the initial dose is so little to cure, cost and time for perfect treatment, number of office visits and morbidity due to untreated hyperthyroidism are markedly increased.
Conclusion: Regarding lower rate of failed therapy with 10 mCi, and as there is no significant difference in late hypothyroidism between low doses and high doses of I-131, we concluded that 10 mci is the optimal fixed dose for treatment of Graves' disease.

Abstract
Because of high prevalence of upper limbs pain and carpal tunnel sndrome and the need of proofing of diagnosis by nerve conduction study (NCS) testing of edian nerve is one of the most common exams in electro-diagnostic centers. In interpretation of findings of nerve conduction study presence of a normal range for findings is one of the most important points.
Materials and Methods: In this study we obtained the findings of nerve conduction study of median nerve in 60 normal persons.
Results: The mean of motor distal latency was 3.09 ms (SD: 0.35). The mean of sensory distal latency measured to peak of response was 3.04 ms (SD: 0.28) with increasing age mean of motor and sensory distal latencies increased. Most of findings had no significant difference with other references.
Conclusion: There is no problem in using of the normal ranges of the other countries for Iranian patients.

Abstract
This article is to verify mortality rate, cause of death, severity of injury (ISS),GCS, patient fate in hospital, pattern of specific organ injuries and some other characteristics among injured pedestrians and car occupants referred to three trauma centers in Tehran (Sina hospital, Shohada Tajrich hospital, Fayazbakhsh hospital) from May 1996 until May 1997.
Materials and Methods: 57367 patients were admitted to emergency department of these centers among which, 6027 victims of motor-vehicle accidents were included in this study.
Results: 71% of cases were pedestrians and rest was car occupants. M/F ratio was 1.8/5. Mean age was 29y. Motor vehicle accidents occurred most commonly during nights. The patients' GCS at arrival in emergency department had similar distribution in both groups. The most commonly injured organs in both groups were: integument, head and neck, extremities and bony pelvis. Thoracic and spinal injuries were more common among car occupants. Extremities and boney pelvis injuries were more common among pedestrians. The mortality rate was the same between both groups. Mortality rate was affected by GCS at arrival and severity of injury. Mortality rate among the old was 4 times the rate among the children. The accidents most commonly occurred on metropolitan roads and streets. The most common cause of death between both groups was head injury. Surprisingly head injury was a more common cause of death among the car occupants.
Conclusion: Pattern of specific organ injuries was different form the pattern in previous studies as the pattern was virtually the same between both groups except for spinal and thoracic injuries were more common among the car occupants.

Abstract
Preoperative autologous blood donation is commonly used to reduce exposure to homologous blood transfusions among patients undergoing elective cardiac surgery. The aim of this study was to evaluate the effect of autologous transfusion on patients' hematocryte value, intra and postoperative blood loss, hospitalization time, the development of infective complications and other factors.
Materials and Methods: Between June 2001 to April 2002, 208 patients were underwent cardiac surgery in cardiac surgery ward in Imam Khomeini Medical Center. One or more blood units donate from 104 Patients before cardiopulmonary bypass and heparin injection, and transfused to them after CPB and Protamin injection (autologous Group, group 1). 104 patients underwent cardiac surgery routinely (control group, group 2).
Results: Mean of age was 55.9±8.6 in group 1 and 56.6±9.3 in group 2 (P=NS). 73 male and 31 females were in group 1 and 79 males and 25 females were in group 2 (P=NS). Smoking, familial history, hyperlipidemia, diabetes mellitus, renal failure, hypertension, stroke, and history of myocardial infarction was similar in two groups.
Severity of angina, urgency operation, number vessels disease, duration of cardiopulmonary bypass, duration of aortic cross clamp time, use of internal thoracic artery graft, and number of grafts was similar in both groups. Mean of bleeding post operation was 548 cc in group 1 and 803 cc in-group 2 (P=0.003). Bleeding that need to operation was 1.8% in group 1 and 8.6% in group 2 (P=0.002). Wound infection, mediastinitis, renal failure, ventilatory prolonged, stroke, need to Intra-aortic Balloon Pump (IABP), intraoperative bleeding, and hospital stay was similar in both groups. Mean of extubationt time was 10.2 hours in group 1 and 14.8 hours in group 2 (P=0.001).
Conclusion: Preoperative and intra-operative donations are safe and continue to contribute uniquely to blood conservation, providing important options in comprehensive blood conservation programs in current pediatric open-heart surgery.

Abstract
Autonomic nervous system dysfunction in diabetics can occur apart from peripheral sensorimotor polyneuropathy and sometimes leads to complaints which may be diagnosed by electrodiagnostic methods. Moreover glycemic control of these patients may prevent such a complications.
Materials and Methods: 30 diabetic patients were compared to the same number of age and sex-matched controls regarding to electrophysiologic findings of autonomic nervous system. Symptoms referable to autonomic disorder including nightly diarrhea, dizziness, urinary incontinence, constipation, nausea, and mouth dryness were recorded in all diabetic patients. Palmar and plantar SSR and expiration to inspiration ratio (E: I) and Valsalva ratio were recorded in all diabetics and control individuals by electromyography device. In addition NCS was performed on two sensory and two motor nerves in diabetic patients.
Results: There was no relation between age of diabetics and abnormal D: I ratio, Valsalva ratio and degree of electrophysiologic autonomic impairment. Also no relation between peripheral sensorimotor polyneuropathy and electrophysiologic autonomic impairment was found. Plantar SSR was absent in 80% of diabetics with orthostatic hypotension (p~ 0.019). Palmar and plantar SSR were absent in many diabetics in comparison to control group (for palmar SSR p~ 0.00 and for plantar SSR p< 0.015). There was no relation between diabetes duration since diagnosis and electrophysiologic autonomic impairment.
Conclusion: According to the above mentioned findings diabetic autonomic neuropathy develops apart from peripheral sensorimotor polyneuropathy and probably with different mechanisms. Remarkable absence of palmar SSR in diabetics with orthostatic hypotension can be due to its sympathetic origin. Absence of any relation between diabetes duration and electrophysiologic autonomic impairment can be due to late diagnosis of type 2 diabetes or no pathophysiologic relation between chronic hyperglycemia and autonomic neuropathy.

Abstract
Background: Today, coronary artery disease is a leading cause of death and morbidity in the world and recognition of all aspects of this problem appears to be necessary and important. In recent years in addition to traditional coronary risk factors, other new risk factors are presented that can affect coronary arteries and accelerate atherosclerosis process. One of the most important of these, are infections, specially with Chlamydia pneumonia. We aimed to study this possibility that is whether correlation between infection with Chlamydia pneumonia and Acute Myocardial Infarction. (AMI).
Materials and Methods: This research is a descriptive case-control study which evaluates frequency of infection with Chlamydia pneumonia in the 100 patients with AMI and 105 patients without any history or evidence of CAD admitted in sections of CCU and surgery, in Dr. SHARIATI and SINA hospitals in 2001. For this purpose we took 5ml blood sample from all of the patients, and tested for specific anti Chlamydia pneumonia antibodies (IgG & IgM) by ELISA method.
Results: Our study showed that 38 percent of control group patients and 54 percent of patients with AMI had positive titer of anti Chlamydia pneumonia antibody and so they were infected with Chlamydia pneumonia {OR= 1.9 (95% CI: 1.34 to 2.46)} (P< 0/001).
Conclusion: This study demonstrates that, there is significant correlation between infection with Chlamydia pneumonia and occurrence of AMI so treatment of this infection could be of profit.

Abstract
Background: The idea of integration of medical education into health care system with the goal of comprehensive self sufficiency and complete response to public health needs were initiated in 1985. There were many prose and cones in this procedure which raised many controversies. The dilemma about strengths and weaknesses increased in 2002 during which Iran parliament tried to change the situation. In this study we tried to conclude and exit the dilemma.
Materials and Methods: We studied the attitude of key academic person regarding the integration. In a cross-sectional study using a pretested questionnaire, we assessed the attitude of 556 academic staffs and managers from eight randomly selected medical universities.
Results: Most of respondents agreed the positive out come of integration like establishment of disease surveillance and improving in health indicators, but they believed that the quality of medical education has decreased. Most of respondents suppose that dissociation of medical education may cause a lot of problems.
Conclusion: There are a lot of controversies regarding the strengths and weaknesses of integration. External factors were causes of decreasing the quality of education so it is important to decide about the future by considering external factors.

Abstract
Background: The purpose of this study was to evaluate the effect of treatment with radioactive iodine on the function of gonads in males and females with follicular and papillary thyroid carcinoma.
Materials and Methods: Consenting patients in the reproductive age were grouped according to the cumulative dose of received radioiodine and followed for at least 12 months. For all men, serum levels of FSH, LH, and testosterone were measured some (53 cases) were also studied by semen analysis. For women, tests for serum levels of LH, FSH, estrogen, and progesterone were performed.
Results: Overall, 246 patients (159 females, 87 males) were studied. In 87.4% of men, there was an increase in serum FSH level after radioiodine therapy, in 20.7% of whom the level remained high during follow-up period. The average serum level of FSH after each course of treatment was significantly higher than the level before treatment (p<0.01), and there was a meaningful correlation with the cumulative dose of received iodine (p<0.001). Reduced number of sperms was shown in 35.8% of male patients, among whom 73.7% also showed reduced motility. In 36.8% of the patients with reduced sperm number (13.2% of the total), this finding was persistent during the follow-up period. Increased level of FSH was correlated with reduced sperm counts in all doses (p

Abstract
Background: Hematopoietic stem cell (HSC) transplantation has brought the possibility of the use of high dose chemotherapy in the treatment of malignant hematopoietic diseases. Short-term HSC preservation at 4˚C is the most common method for autologous peripheral blood stem cell transplantation (PBSCT).
Materials and Methods: Thirty-seven mobilized PBSC samples from thirteen hematological patients (4 AML, 4 MM and 5 Lymphoma cases) who were selected for autologous PBSCT and 24 normal candidates for allogenic PBSCT were preserved in five separate sterile 2 ml tubes in 4˚C. Each sample was evaluated for total nucleated cell (TNC) count, dye exclusion cell viability and Granulocyte-Macrophage colony forming unit (GM-CFU in semisolid medium after 16 days) in days 0, 2, 4, 6 and 8. The results were converted to percentages of day 0 measures. The data were analyzed by SPSS 10.0 using Paired Samples T test, Independent Samples T test and Regression.
Results: The mean percentages (and standard deviations) of TNC count, cell viability and GM-CFU for days 0, 2, 4, 6 and 8 are shown below:
No significant correlation was found between age, sex, weight and the kind of donor with TNC, viability and GM-CFU.
Conclusion: In this study, we have found that during storage of mobilized PBSC in 4˚C, TNC count and cell viability still remains higher than 70% after eight days, while GM-CFU decreases more rapidly and falls to less than 50% after day 4.Therefore, TNC count and cell viability do not decrease as fast as GM-CFU.

Abstract
Background: Pulmonary involvement is a common and serious complication of rheumatoid arthritis. This cross sectional study sought to determine the prevalence of pulmonary disease in patients with rheumatoid arthritis on the basis of history, physical examination, chest X-ray and PFT.
Materials and Methods: 103 patients (81 Women, 22 Men) fulfilling the ACR (American College of Rheumatology) criteria for RA (Rheumatoid arthritis) were consecutively included in a cross sectional study. Detailed medical (including respiratory symptoms and the disease activity symptoms) and drug and occupational histories and smoking were obtained. All patients underwent a complete pulmonary and rheumatologic examination and conventional chest radiography. All patients underwent PFT that comprised spirometry and body plethysmography.Results for PFTs were expressed as percentage of predicted values for each individual adjusted for age, sex, and height.
Results: On the basis of history: Their mean age was 43.3 ± 2.6 years (range: 17-74) and the mean duration of the disease was 69.3 ± 15.6 months. Rheumatoid factor was positive in% 61.2. No patients were 0.5Pack/Year smoker in whole life. Prevalence of pulmonary involvement based on radiographic and pulmonary function test detected in 41 patients (39/7%). The most frequent respiratory clinical finding was dyspnea (33%), (NYHA grade I in 17.5% and NYHA grade II in 15.5%), Cough (with or without sputum) in 13.6 %, Crackle was the most sign in pulmonary examination (5.8%). Chest X-ray was abnormal in 13.3 % that the most common finding in this study was reticulonodular pattern in 20 patients (19.4 %), and pleural effusion detected in 7 patients (6.7%). PFT was abnormal in 30 patients (29.1 %). A significant decrease of FEF 25%-75% below 1.64 SD. Small airway involvements was the most abnormal finding of PFT. No relation between rheumatoid arthritis disease activity (ESR>30, Morning stiffness>30', Anemia, thrombocytosis) with pulmonary disease was seen.
Conclusion: This study suggests a high prevalence of lung involvement in patients with rheumatoid arthritis.Therefore we recommend a complete investigation in patients with RA with any respiratory symptom.

Abstract
Background: Graft-versus-host disease is one of the major complications after allogenic bone marrow transplantation, but it is not easy to anticipate the onset. Cytokines released by type 1 T-helper cells are thought to play a pivotal role in acute graft-versus-host disease (aGVHD). The ability to predict the likely occurrence of graft-versus-host-disease (GVHD) after BMT would be extremely valuable. By serially measuring serum levels of soluble IL-2 receptor (sIL-2R), IL-18 and following allogeneic bone marrow transplantation (BMT), we tried to define their relationship to aGVHD as complication of the transplantation and determine useful markers for aGVHD predictors.
Materials and Methods: Serum sIL-2R, IL-18, and levels were measured by sandwich ELISA in 219 sera samples from 39 patients (with hematological disorders before and after allogeneic BMT) and 28 controls. All patients received BMT from HLA-identical siblings.
Results: 25 patients developed aGVHD and serum levels of sIL-2 R and IL-18 , in sera drawn before transplantation , in patients with acute graft-versus-host disease (aGVHD +) , were increased in comparison of patients without acute graft-versus-host disease (aGVHD ¯) and control group and there wasn’t any significant differences in serum levels of sIL-2 R and IL-18 in aGVHD ¯ patients and controls. Serum level of IL-18, in aGVHD+ patients, was increased during day 3 - 24 after BMT, and there was a significant difference in patients with GVHD 0 – GVHD III. In majority of patients with acute GVHD (60 %) , the peak levels of IL-18 and IL-2R was achieved on day 10 after BMT and the rise in sIL-2R and IL-18 preceded of clinical signs of GVHD (mean day 15 after BMT). Level of IL-18 in patients with aGVHD had strongly correlated with the severity of aGVHD on Day 10 after BMT. IL-18 level mean (before BMT), in patients who received Busulfan and Fludarabin to treat aGVHD, was lower than in patients who received Busulfan - Endoxan, or Cyclophosphamide.
Conclusion: Our data concluded that IL-18 plays an important role in the development of aGVHD and IL-18 level might be an indicator for aGVHD, reflecting the severity of the disease. These findings suggest that IL-18 may play important roles in the pathogenesis of aGVHD and that measurement of serum IL-18 levels can be useful predictor of aGVHD.

Abstract
Background: To evaluate the ability of Ankle/Brachial Index (ABI), that is a sensitive and specific test for detection of PAD, to foretell the possibility of ischemic heart diseases in diabetic patients.
Materials and Methods: All of diabetic patients who visited in our diabetes research center between May 2000 and May 2001 and were confirmed diabetics since 2 or more years ago were enrolled in the study. The ABI was calculated for all of the patients and their demographic specifications and ischemic heart disease risk factors were recorded. All of the patients refer to perform an exercise test, but 279 patients were conferred to performing stress test. They were containing: 127 patients with ABI =<1.1(group I) and 47 patients with ABI>=1.4(group III) as case groups and, 105 patients with 1.1 60 years (P = 0.02). 238 patients were in group I (25.1 %), 625 patients in group II (65.9 %) and 85 patients in group III (9 %). 52.8% of 125 patients in Group I, 19.6% of 107 patients in group II, and 44.7% of 47 patients in Group III had positive exercise test. I, II (P 0.00)- II , III (P = 0.05) A total of 108 patients from among the 279 patients had positive exercise test (38%), and most of them were from groups I &III. 72.2% of group I , and 52.5% of group II had high blood pressure (P 0.00). Both hypertensive and normotensive patients with ABI =<1.1 & >=1.4 had positive exercise test significantly more than patients with 1.1=1.4 is an independent predictor of coronary artery diseases in diabetic patients especially in those who are hypertensive.

Abstract
Background: The aim of this investigation is to evaluate the histologic results of biopsy in women with atypical squamous cells of undetermined significance (ASCUS) cytologic diagnosis.
Materials and Methods: We reviewed a series of cases with ASCUS pap smears from March 1999 to Feb 2002 in Imam Khomeini Hospital (n= 104), Who had cervical biopsy indirected colposcopy (103) and in Onec endocervical biopsy obtained without colposcopy. In 60 patients before colposcopy and biopsy repeat pap smear was tabled.
Results: Biopsy revealed 28.8% SIL (14 LSIL and 16 HSIL), 1 invasive carcinoma and 1 endometrial carcinoma. Pap smear repeated for 60 women before colposcopy examination, which 7 (11.7%) of them were normal. ASCUS persisted in 45 cases (75%) and 8 cases (13.3%) turned out to be SIL (6 LSIL, 2 HSIL) of 7 normal repeat smear, 2 marked as LSIL by biopsy. In colposcopic examination 22 of 103 (21.4%) had normal view which one of them was LSIL histologically.
Conclusion: Based on these findings, it seems immediate colposcopy and directed biopsy are appropriate procedures for management of ASCUS and to detect underlying SIL.

Abstract
Background: This research was conducted for the purpose of determining the effect of hormonal and non-hormonal contraception on the mother milk and infants growth among lactating women received by south Tehran’s Health Centers. In this regard a broad spectrum study from December 2000 until February 2001 was done by Tehran university.
Materials and Methods: By sampling method, 200 lactating women were chosen randomly. They were divided into two groups according to their preferred method of contraception: 67 women chose hormonal method and 133 women chose non –hormonal method.
Results&Conclusion: During the time of the study on infants growth (increase in head circumstances, increase in height, increase in weight), There was no significant difference between the two groups. If we take the effect of contraceptive methods into consideration, the Triglyceride levels in non-hormonal group were increased considerably compared to the other group. Other ingredients were almost the same.

Abstract
Background: The important of angiogenesis for the progressive growth and viability of solid tumors is well established. Only few data are available for hematologic neoplasms.
Materials and Methods: To investigate the role of angiogenesis in the acute myloid leukemia (AML) bone marrow biopsies from 30 adults with newly diagnosed, untreated AML(day 0) were evaluated. Further studies were done after completion on remission induction of treatment (day 35 of 7×3 regimen n=13, complete remission in AML (m3) treat with arsenic trioxide n=17). Micro-vessels were scored in at least 3 areas of highest micro-vessel density in representative section of each bone marrow specimen using immunohistochemistry for Von Willbrand factor.
Results: Median micro-vascular density (MVD) were in AMLM3 patients before treatment, %6.81±3.58 and after treatetment %3.48±3.06 (p<0.0001). In other AML patients MVD were befor treatment %3.38 and after treatment %3.6.
Conclusion: In conclusion, there is evidence of increased micro-vessel density in the bone marrow of patients with AML, which supports the hypothesis of an important role of angiogenesis in AML. MVD was reduced with chemotherapy and arsenic. Furthermore , these finding suggest that antiangiogenesis therapy might constitute a novel strategy for the treatment of AML.

Abstract
Background: Adolescence (10-19 years) is one of the most challenging periods in human development. A second period of rapid growth occurs during the teen years. Not much information is available on the effect of the socio-economic status on the outcome of nutrition education in teenage girls. Objective : The purpose of this study was to determine the effect of socio- economic status on the efficacy of nutrition education in promoting the nutritional knowledge, attitude and practice in first-grade guidance school girls in Tehran.
Material & Methods: A total of 300 students were selected from 11 guidance schools by simple sampling and divided into three groups: 1- guide-book, 2- group discussion, 3- control. The knowledge and attitude data were collected using pre-test and post-test questionnaires and the personal-socioeconomic data were collected using general questionnaires. The students in group 1 were given the guide-book and required to study it at home, while group 2 students were told to discuss among themselves the contents of the guide-book. The control group was given nothing to study or to do.
Results: Nutrition education did not have a significant effect on the increase in the attitude score in the students whose grade-point average and their mother’s education level were high. (p= 0.13, p=0.29). Only mother’s education level independently from the type of education was associated with the difference of knowledge score means (p =0.07).There was interaction between nutritional education and monthly pocket- money with regard to the increase in the knowledge score (p =0.03).
Conclusion: Overall, exception of monthly pocket money, the effect of education on the nutritional knowledge and attitude was independent from other variables. Only mother’s education associate with the difference of knowledge score means.

Abstract
Background: Chang in the serum K+ level may increase perioperative morbidity and mortality in kidney transplant recipients. Thus this research was done with the aim of evaluated of K+ change in kidney transplant recipients. Hence the following study was carried to evaluate the fluctuation of potassium ion in the kidney transplant recipient patients.
Materials and Methods: In a simple randomized clinical trial the serum K+ level was assessed in 40 kidney transplant candidates as following interval, pretransplantation, during renal art, anastomosis, after diuresis and post transplantation period. After hydration with 5 ml/kg normal saline all patient were undergone general anesthesia identically. They were premedicated fentanyl (2µg/kg), induction was performed by thiopental sodium (5 mg/kg). Tracheal intubation was facifitated with atracurium (0.6 mg/kg). Anesthesia was maintained with N2O + O2 50%, halothane 0.1% and fentonyl 1 µg/kg every 30 min.
Results: The least mean K+ level was during anastomosis (ie. 3.5±0.24 mmol/L) and showed a decrease in the serum K+ level compared to preoperative period (mean 4.4±0.48 mmol) (P< 0.001). The maximum serum K+ level detected preoperatively and postoperatively were 5 (mmol/ L) and 4.7 (mmol/L) respectively.
Conclusion: Despite the above results we inferred that range of serum K+ level was maintained within normal. Therefore with suitable pereoprative assessment hyperkalemia is a rare occurrence in transplant recipients.

Hence the following study was carried to evaluate the fluctuation of potassium ion in the kidney transplant recipient patients.
Materials and Methods: In a simple randomized clinical trial the serum K+ level was assessed in 40 kidney transplant candidates as following interval, pretransplantation, during renal art, anastomosis, after diuresis and post transplantation period. After hydration with 5 ml/kg normal saline all patient were undergone general anesthesia identically. They were premedicated fentanyl (2µg/kg), induction was performed by thiopental sodium (5 mg/kg). Tracheal intubation was facifitated with atracurium (0.6 mg/kg). Anesthesia was maintained with N2O + O2 50%, halothane 0.1% and fentonyl 1 µg/kg every 30 min.
Results: The least mean K+ level was during anastomosis (ie. 3.5±0.24 mmol/L) and showed a decrease in the serum K+ level compared to preoperative period (mean 4.4±0.48 mmol) (P< 0.001). The maximum serum K+ level detected preoperatively and postoperatively were 5 (mmol/ L) and 4.7 (mmol/L) respectively.
Conclusion: Despite the above results we inferred that range of serum K+ level was maintained within normal. Therefore with suitable pereoprative assessment hyperkalemia is a rare occurrence in transplant recipients.
