Why potential donors and recipients not proceed to live kidney transplantation, malatya algorithm / Por qué los donantes y receptores potenciales no proceden al trasplante de riñón vivo, algoritmo de malatya

ABSTRACT Introduction: In some countries, organ donation is not widespread enough due to medical, cultural, ethical and socioeconomic factors. Living-donor kidney transplant constitutes the main source of kidney donation. Aim: To evaluate the causes of cancellation of living-donor kidney transplant and improve the effectiveness of transplant programs. Methods: Medical records of possible donors and recipients who were evaluated for living-donor kidney transplant at a tertiary medical center between November 2010 and September 2019 were reviewed retrospectively. Results: Evaluations were performed on 364 potential donors and 338 living-donor kidney transplant recipients; 207 of the latter (61.24%) underwent living-donor kidney transplant. Immune disorders represented the majority of cancellations (38.84%). Fifty-six donors (15.38%) were rejected mainly due to renal disorders (39%). Conclusion: Timely referral of patients to transplant centers must be guaranteed in order to overcome immune problems. Transplant centers should invest in programs adequate both for their resources and for their patients: paired kidney exchange, desensitization protocols, future research, etc.

RESUMEN Introducción: En algunos países la donación de órganos no es suficiente debido a factores médicos, culturales, éticos y socioeconómicos. El donante vivo de riñón constituye la principal fuente de donación de riñones. Objetivo: Evaluar las causas de cancelación de los donantes vivos de riñón y mejorar la eficacia de los programas de trasplante. Material y métodos: Se evaluaron retrospectivamente los registros médicos de posibles donantes y receptores para trasplante de riñón con donante vivo en un centro terciario, entre noviembre de 2010 y septiembre de 2019​​. Resultados: Se evaluaron 364 donantes potenciales y 338 receptores de trasplante de riñón con donante vivo; 207 receptores (61,24%) se sometieron a trasplante de riñón con donante vivo. Los problemas inmunológicos ocasionaron la mayoría de las cancelaciones (38,84%). A cincuenta y seis donantes (15,38%) se les negó la donación, principalmente debido a problemas renales (39%). Conclusión: La derivación oportuna de los pacientes a los centros de trasplante debe garantizarse para superar las barreras inmunológicas. Los centros de trasplante deberían invertir en programas adecuados, tanto por sus recursos como por los pacientes: protocolos de desensibilización, trasplante renal cruzado, investigación futura, etc.

A Novel Technique in the Treatment of Lymphoceles After Renal Transplantation: C-Arm Cone Beam CT-Guided Percutaneous Embolization of Lymphatic Leakage After Lymphangiography.

BACKGROUND: We aimed to evaluate the efficacy of percutaneous embolization after lymphangiography using C-arm cone-beam computed tomography (CBCT) performed at the site of lymphatic leakage in patients with postrenal transplant lymphocele. METHODS: Between July 2014 and August 2017, 13 patients not responding to percutaneous ethanol sclerotherapy and conservative treatment for recurrent lymphocele after renal transplant were included. The mean age of the patients was 56.38 ± 9.91 (range, 36-70) years, and it comprised 9 men and 4 women. All patients underwent intranodal lymphangiography. C-arm CBCT-guided percutaneous embolization was performed in patients with confirmed lymphatic leakage. Patients who had no lymphatic leakage underwent drainage with fibrin glue injection. RESULTS: Lymphatic leakage was observed in 9 patients after lymphangiography, and they underwent CBCT-guided percutaneous N-butyl-2-cyanoacrylate embolization. The volume of lymphatic drainage reduced to less than 10 mL in 8 patients. One patient who was not responding to embolization was treated surgically, after percutaneous drainage and fibrin glue injection. Lymphatic leakage was not observed in 4 patients after lymphangiography. Of these, 3 patients showed a reduction in the amount of lymphatic drainage after lymphangiography. All 4 patients underwent percutaneous drainage and fibrin glue injection. One patient did not respond to the treatment and was treated surgically. Prelymphangiography and postlymphangiography and embolization, the volume of lymphatic drainage was 113.07 ± 21.75 mL, and 53.84 ± 30.96 mL, respectively, and statistically significant decrease was detected (P < 0.005). CONCLUSIONS: Lymphangiography and CBCT-guided percutaneous embolization procedures might be an effective treatment method for patients with lymphocele refractory to treatment.

Management of non-vascular complications following renal transplantation using percutaneous approach.

OBJECTIVE: Non-vascular complications following renal transplantation can cause graft failure. In this study, we present our two-year experience with percutaneous treatment for non-vascular complications following renal transplantation. PATIENTS AND METHODS: A total of 30 patients who underwent percutaneous radiological treatment between March 2014 and July 2016 were included in the study. RESULTS: Following renal transplantation, a total of 36 percutaneous radiological procedures which includes hydronephrosis secondary to ureteral stricture (n. 15), clinical symptom-producing lymphocele due to pressure (14) and creatinine elevated nondilated grafts (n. 7) after excluding other reasons of creatinine elevation, were performed. Six patients received percutaneous treatment for both ureteral stricture and lymphocele. The patients underwent balloon dilatation and double- J ureteral stent due to ureteral stricture. The mean pre- and post-procedural creatinine levels were 4.36 ± 2.84mg/dL and 2.17 ± 1.24 mg/dL respectively (p=0.004), indicating a significant difference. For lymphocele treatment, sclerosing agents were injected and lymphatic leakage areas were injected with percutaneous glue. The mean pre- and post-procedural creatinine values were 2.97 ± 1.78 mg/dL and 1.75 ± 1.18 respectively (p=0.002), indicating a significant difference. Nephrostomy catheters were placed for patients with elevated creatinine levels and non-dilated collecting system. The mean pre- and post- nephrostomy creatinine levels were 3.55 ± 2.36 mg/dL and 2.57 ± 1.82 mg/dL respectively (p>0.05), indicating no statistically significant difference. CONCLUSION: The results of our study suggest that percutaneous treatment is an effective method for the treatment of non-vascular complications following renal transplantation, and, therefore, should be the first option for the preservation of graft functions. KEY WORDS: Percutaneous treatment, Renal transplantation.

Neutrophil gelatinase-associated lipocalin reflects the severity of anemia without iron deficiency and secondary hyperparathyroidism in hemodialysis patients.

OBJECTIVE: Secondary hyperparathyroidism (SHPT) and anemia are the primary and most common complications in patients receiving hemodialysis (HD). Neutrophil gelatinase-associated lipocalin (NGAL) is a new marker to assess iron deficiency and manage iron therapy for HD patients. The aim of this study was to determine any association between serum NGAL level and anemia without iron deficiency in patients with SHPT on chronic HD. METHODS: Total of 61 SHPT patients on chronic HD were enrolled in the study and divided into 3 groups: mild SHPT group (n=17), moderate SHPT group (n=21), and severe SHPT group (n=23). Hemogram, biochemical assays, and level of ferritin, high sensitivity C-reactive protein (hs-CRP), and NGAL were evaluated in all groups. RESULTS: Serum NGAL level was significantly higher and hemoglobin (Hb) level was significantly lower in severe SHPT patients compared with both mild and moderate SHPT patients. Furthermore, in severe SHPT group, serum NGAL level was significantly positively correlated with serum parathyroid hormone (r=0.79; p=0.00) and hs-CRP (r=0.52; p=0.01) level and negatively correlated with serum Hb (r=-0.56; p=0.00) level. CONCLUSION: SHPT was important factor affecting anemia in HD patients. Even when iron deficiency anemia is excluded in patients with SHPT, there was significant negative correlation between serum NGAL and Hb.

Relationships between plasma pentraxin 3 levels and inflammation markers patients with tunneled permanent catheter in hemodialysis.

PURPOSE: Vascular access (VA) devices may contribute to chronic inflammation in hemodialysis (HD). Pentraxin 3 (PTX3) is a recently discovered acute phase protein that responds more rapidly than other inflammatory markers. This study compared PTX3 and other markers between HD patients and healthy controls. METHODS: The study population included 30 patients with tunneled permanent catheter (TPC), 30 patients with arteriovenous fistula (AVF) and 30 healthy controls. Hemogram, biochemical assays, ferritin, high sensitive C-reactive protein (hs-CRP), tumor necrosis factor-α (TNF-α) and PTX3 were evaluated in all groups. RESULTS: PTX levels were highest in HD patients with TPC, intermediated in HD patients with AVF and lowest in healthy controls (5.2 + 2.4 vs. 3.1 + 1.3 vs. 1.8 + 0.7, p<0.001 for all comparisons). PTX3 levels correlated strongly to hs-CRP (r = 0.857) and moderately to TNF-α, NLR, ferritin and total neutrophil count. PTX3 and albumin levels had a negative correlation. PTX3 levels were higher in patients with 8 months of TPC than those with 7 months or less. CONCLUSIONS: PTX3 levels are significantly elevated in all patients on HD, but presence and extended duration of TPC are associated with incrementally higher levels of PTX3 and other inflammatory markers. PTX3 and NLR may be useful in assessing chronic inflammatory states in HD.

Relationship between vitamin D and lung function, physical performance and balance on patients with stage I-III chronic obstructive pulmonary disease / Relação entre vitamina D e função pulmonar, desempenho físico e equilíbrio em pacientes em estágio I a III de doença pulmonar obstrutiva crônica

Summary Objectives: vitamin D is important for muscle function and it affects different aspects of muscle metabolism. This study aim to determine whether serum 25(OH) D levels are related to lung functions, physical performance and balance in patients with chronic obstructive pulmonary disease (COPD). Methods: in 90 patients with COPD and 57 healthy controls lung function tests, physical performance tests (time up and go, gait velocity test, sit-to-stand test, isometric strength, isokinetic strength), static (functional reach test) and dynamic (time up and go) balance tests and the association of 25(OH)D levels with lung functions, physical performance and balance were evaluated. Results: the COPD patients had significantly more deficit in physical function and balance parameters, and in dynamic balance test (p<0.005). Isokinetic knee muscle strength (flexor and extensor) in COPD patients was significantly lower than in the controls (p<0.05); FEV1 (p=0.008), FVC (p=0.02), FEV1/FVC (p=0.04), TLC (p=0.01) were lower in COPD patients with vitamin D deficiency [25(OH) D less than 15ng/mL] than in COPD patients without vitamin D deficiency. Hand grip test (p=0.000) and isokinetic knee muscle strength (flexor and extensor) (p<0.05) were also lower in COPD patients with vitamin D deficiency. Vitamin D deficiency was more pronounced in patients with stage III COPD (p<0.05). Conclusion: patients with COPD had worst physical functioning, poor balance and less muscle strength. Severe disturbed lung and peripheral muscle functions are more pronounced in COPD patients with vitamin D deficiency. .

Resumo Objetivos: a vitamina D é importante para a função muscular e afeta diferentes aspectos do metabolismo muscular. O objetivo é determinar se os níveis séricos de 25 (OH) D estão relacionados com as funções pulmonares, desempenho físico e equilíbrio em pacientes com doença pulmonar obstrutiva crônica (DPOC). Métodos: em 90 pacientes com DPOC e 57 controles saudáveis, testes de espirometria, testes de desempenho (tempo de levantar e ir, teste de velocidade da marcha, teste sitto-stand, força isométrica, força isocinética) e testes de estática (teste de alcance funcional) e dinâmica (tempo de levantar e ir) de equilíbrio foram realizados; e foram avaliados a associação de níveis de 25 (OH) D com as funções pulmonares, desempenho físico e equilíbrio. Resultados: os pacientes com DPOC apresentaram significativamente mais déficit nos parâmetros de função e equilíbrio físico, e no teste de equilíbrio dinâmico (p<0,005). Força muscular isocinética do joelho (flexores e extensores) em pacientes com DPOC foi significativamente menor do que nos controles (p<0,05); VEF1 (p=0,008), CVF (p=0,02), VEF1/CVF (p=0,04), CPT (p=0,01) foram mais baixos em pacientes com DPOC e com deficiência de vitamina D [25 (OH) D menor do que 15 ng/ml] do que em pacientes com DPOC sem deficiência de vitamina D. Os resultados do teste da força de preensão manual (p=0,000) e força muscular isocinética do joelho (flexor e extensor) (p<0,05) também foram menores nos pacientes com DPOC e com deficiência de vitamina D. A deficiência de vitamina D foi mais pronunciada em pacientes em estágio III da DPOC (p<0,05). Conclusão: pacientes com DPOC tiveram pior desempenho físico, falta de equilíbrio e menor força muscular. Perturbações graves das funções pulmonares e musculares periféricas são mais pronunciadas em pacientes com DPOC e com deficiência de vitamina D. .

NGAL and NT-proBNP levels in diabetic patients with macroproteinuria.

BACKGROUND: In patients with heart failure plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) levels are correlated to urine neutrophil gelatinase-associated lipocalin (NGAL) levels. We prospectively evaluated the relationship among glomerular filtration rate (eGFR), urine albumin-to-creatinine ratio (ACR), urine and serum NGAL and NT-proBNP levels in 20 type II diabetic patients with macroalbuminuria at 4-month intervals. RESULTS: Compared with 20 age, gender-matched healthy controls, diabetic patients had higher urine and serum NGAL, serum NT-proBNP and lower eGFR. The eGFR of the patients at the baseline, the 4th and the 8th month were 29.6 ± 12.0, 27.8 ± 13.7 and 22.9 ± 10.4 mL/min/1.73 m(2), respectively. No significant change in urine NGAL levels was detected (p > 0.05), whereas there were significant increases in NT-proBNP, serum NGAL and urine ACR and significant decrease in eGFR as the study progressed (p < 0.05). Both the baseline and the 4th month urine ACR were positively correlated to NT-proBNP levels measured at the same periods (r: 0.451; p: 0.046; r: 0.489; p: 0.029 respectively). In all measurements, urine ACR was negatively correlated to serum albumin levels measured at the same periods (r: -0.792; p: 0.000; r: -0.716; p: 0.000; r: -0.531; p: 0.016 respectively). None of eGFR measurements was correlated with NT-proBNP (p > 0.05). Neither serum NGAL nor urinary NGAL levels are associated with NT-proBNP (p > 0.05). CONCLUSION: Our findings show an association between NT-proBNP and proteinuria in type II diabetic patients with macroalbuminuria but not with serum and urine NGAL.

Aluminum toxicokinetics in peritoneal dialysis patients.

CONTEXT: Despite the risk of aluminum (Al) toxicity in dialysis patients, little is known about its toxicokinetics (TK) in this population. A national contamination of dialysate solutions with Al provided the opportunity to study Al TK in peritoneal dialysis (PD) patients and to better understand the influence of covariates on its disposition. METHODS: Al levels in serum and dialysate as well as other laboratory values were collected prospectively from 83 PD patients after correction of Al contamination. Population TK analyses were conducted with NONMEM VI using standard model discrimination criteria. Covariate analyses were also performed using stepwise forward regression followed by backward deletion. RESULTS: After correction of Al exposure, serum levels declined in a biphasic manner, which was captured by the TK model. The TK of Al were best described by a 2-compartment model with linear elimination. Total creatinine clearance was a significant covariate for total clearance (CL). Mean parameter estimates for volume of central compartment (V1), CL, volume of peripheral compartment (V2), volume of distribution at steady-state (Vss), and intercompartmental clearance (Q) were 168 L, 8.99 L/day, 12 000 L, 12 168 L, and 4.93 L/day, respectively. Inter-individual variability for CL and V2 were 22.6 and 51.1%, respectively. Al distributional half-life was 8.5 days, while the terminal elimination half-life was 7.2 years. This model confirms that the large Vss reflects the widespread distribution of Al in bone, lungs, liver, and other tissues. CONCLUSION: This study describes the first population Al TK model in a large group of PD patients, which includes a covariate effect. The model confirms the extensive half-life and tissue distribution of Al in a dialysis-dependent population.

Peritoneal dialysis in the nursing home.

UNLABELLED: The mean age of patients with end-stage renal disease increases steadily. The elderly on dialysis have significant comorbidity and require extra attention to meet their dialysis, dietary, and social needs, and some may need to be treated at a long-term care facility such as a nursing home (NH). Providing dialysis and caring for elderly patients in a nursing home (NH) presents a number of challenges. Few data are available in the literature about elderly patients on peritoneal dialysis (PD) in an NH. This paper describes our experience of starting and maintaining a peritoneal dialysis program in three community-based nursing homes. RESULTS: During the period 2004-2008, after the nursing home personnel had received appropriate training, we established a PD program in three community-based nursing homes and admitted 38 patients on peritoneal dialysis. We educated 112 NH staff over the three-year period. Mean age of the patients at entry was 77.3 + or - 8.5(18.4%) were male. The main causes of end-stage renal disease were diabetes mellitus (DM) 21 (55.8%) and hypertension 13 (34.2%). Comorbid conditions included DM (27, 71.1%), hypertension (26, 68.4%), coronary artery disease (18.5%), chronic heart failure (11, 28.9%), cerebrovascular event (12, 31.6%), and cancer(3, 7.9%). The average total time on chronic peritoneal dialysis was 36.5 + or - 29.8 months, (median 31, range: 1-110 months) of which the average time in the NH program, as of the time of this report, was 18.4 + or - 13.1 months (median 15.5, range: 1-45 months). During the study period, 16 (42.1%) of the patients died, 2 (5.3%) transferred to HD, 2 (5.3%) stopped treatment, and 18 (47.4%) are still in the program. Actuarial patient survival from entry into the NH program was 89.5% at six months, 60.5% at 12 months, 39.5% at 24 months and 13.2% at 36 months. Patient survival from initiation of chronic dialysis was 89.5% at six months, 76.3% at 12 months, 63.1% at 24 months, and 39.5% at 36 months. We observed 28 episodes of peritonitis with a rate of one episode every 40.3 treatment-months. Two PD catheters had to be replaced, giving a rate of one in every 362.5 patient months. CONCLUSION: Our results with elderly patients in a nursing home show an excellent patient and technique survival and a low peritonitis rate. With appropriate training of the NH nursing staff, peritoneal dialysis could be performed successfully in these nursing homes. Successful peritoneal dialysis in a nursing home requires a close collaboration between the nursing home staff and PD dialysis unit.

Renal Behçet's disease: an update.

OBJECTIVE: The aims of this study are (1) to report 33 patients with Behçet's disease (BD) having various renal manifestations, and (2) to update current data using our patients and published papers about BD and renal manifestations. METHODS: The PubMed database was searched using the terms BD or Behçet's syndrome. We found reports of 94 patients (including ours) with BD and specific renal diseases (amyloidosis, 39; glomerulonephritis [GN], 37; renal vascular disease, 19; interstitial nephritis, 1). RESULTS: The presentation of renal disease was edema/nephrotic syndrome in 12 patients (36%). Renal disease was incidentally diagnosed by routine urine analysis and measurement of serum creatinine level in 20 patients (61%). Renal failure was present in 23 patients (70%) and 5 of them have had cyclosporine treatment. The frequency of renal disease among BD patients has been reported to vary from less than 1 to 29%. CONCLUSIONS: The clinical spectrum of renal BD shows a wide variation. Amyloidosis (AA type), GN, and macroscopic/microscopic vascular disease are the main causes of renal BD. Patients with vascular involvement have a high risk of amyloidosis and amyloidosis is the most common cause of renal failure in BD. Several types of glomerular lesions are seen in BD. Current treatment options for renal BD are not evidence based. Radiological vascular intervention combined with immunosuppressive drugs can be useful in selected cases. Routine urine analysis and measurement of serum creatinine level are needed for early diagnosis of renal BD.

Serum leptin, resistin, and lipid levels in patients with end stage renal failure with regard to dialysis modality.

UNLABELLED: Little information is available on the relationship between serum resistin levels and other adipokines with serum lipid levels and insulin resistance in uremic patients under different dialysis modalities. METHODS: This study investigated the effects of dialysis modality on serum leptin, adiponectin, resistin, interleukin 6 (IL-6), and tumor necrosis factor (TNF) alpha levels in age, sex, and total adipose tissue mass (TATM); matched 30 hemodialysis (HD) patients, 30 continuous peritoneal dialysis (CAPD) patients, and 30 healthy controls; and evaluated the relationship between these adipokines and dyslipidemia and insulin resistance. RESULTS: Serum resistin, adiponectin, IL-6, TNF-alpha, and high sensitive C reactive protein (hsCRP) levels were significantly increased in dialysis patients compared to controls (p < 0.05). In CAPD patients, serum leptin, resistin, triglycerides, and total cholesterol levels were higher than those in HD patients (p < 0.05). Leptin levels were positively correlated with TATM, serum triglycerides, total cholesterol, and low density lipoprotein (LDLc) levels in both dialysis groups. Resistin levels were found to positively correlate with TATM and triglycerides in CAPD patients. No relationship was found between the homeostasis model assessment-insulin resistance index (HOMA-IR) and adipokines studied. CONCLUSION: Serum leptin, resistin, triglycerides, and total cholesterol levels were higher in CAPD patients. Leptin levels were positively correlated with TATM, serum triglycerides, total cholesterol, and LDLc levels in dialysis patients. Resistin levels were positively correlated with TATM and triglycerides in CAPD patients. Glucose load during CAPD may be an important factor in increased in leptin, resistin, triglycerides, and total cholesterol levels in CAPD patients. These results highlight the importance of leptin and resistin as determinants of dyslipidemia, especially in CAPD patients.

25(OH) vitamin D3 in patients with chronic kidney disease and those on dialysis: rediscovering its importance.

In terms of both exogenous sources (diet), and endogenous production (activation through exposure to ultraviolet light), vitamin D is unique. Few foods naturally contain vitamin D and only a few are fortified with vitamin D. Most people get more than 90% of their vitamin D requirements from exposure to sunlight. Those who protect their skin from ultraviolet-B radiation with clothing or sunscreen, the elderly, and dark-skinned individuals have limited capacity to produce vitamin D. Vitamin D deficiency is common in the general population and even more common in patients with chronic renal failure (CKD). Increased use of sun-blocking agents and decreased exposure to sunlight, to reduce the risk of skin cancer, attributed to exposure to UV radiation, may contribute to the increase in vitamin D deficiency in the population. These issues are particularly important in the dialysis population who are at particular risk because these, mostly elderly, individuals have an inactive life style and have reduced exposure to sunshine and UV light, thus limiting the actinic synthesis of vitamin D. The nephrology community seems to have overlooked the importance of vitamin D for overall health and well being in patients with CKD. Recently however, several authors have called attention to the role of plasma 25(OH)D3 levels in mineral metabolism dysregulation in patients with chronic kidney diseases, and those on dialysis. Vitamin D not only contributes to skeletal health but also plays a major role in the health of a wide variety of other organ systems. It seems that vitamin D supplementation is the most effective way of preventing vitamin D deficiency.

Diabetic muscle infarction: an unusual cause of muscle pain in a diabetic patient on hemodialysis.

Diabetic muscle infarction (DMI) is a rare, painful and potentially serious complication in patients with poorly controlled diabetes mellitus and frequently misdiagnosed clinically as abscess, neoplasm, or myositis. A 36-year-old diabetic woman referred to our clinic with severe pain in the left antero-medial thigh. She had a 15-year history of Type 2 diabetes mellitus (DM). She was complicated by diabetic nephropathy and requiring hemodialysis. She had first noticed pain and swelling in her left thigh after a minimal trauma for 2 days prior to presentation. Clinical and laboratory evaluation, and muscle biopsy revealed the diagnosis of muscle infarctions. She did no respond to the conservative therapy. Pain and swelling in her thigh worsened progressively. She underwent surgical debridment and then, her clinical status improved. We describe the characteristic clinical and pathologic findings and the course of the illness with emphasis on the importance of recognition of the syndrome so that unnecessary investigation and overzealous therapy can be avoided.

Possible malignant neuroleptic syndrome that associated with hypothyroidism.

A 54-year-old woman with schizophrenia presented to hospital with unconsciousness, fever and marked muscle rigidity. She had been given fluphenazine decanoete 20 mg intramuscularly 15 days before the admission and she had continued taking haloperidol 20 mg daily and oral biperiden 2-4 mg. She was extremely rigid and unresponsive. On laboratory investigations revealed: serum sodium 120 mEq/l, creatinine phosphokinase 12,980 IU/l (normal up to 170), lactate dehydrogenase 1544 IU/l (150-500), free trioidothyronine < 1.00 pg/ml (1.5-4.5), free throxyine 0.76 ng/dl (0.8-1.9), thyroid stimulating hormone 1.14 microU/ml (0.4-4), cortisol (at 8.00 a.m.) 9 microg/dl (5-25). Antipsychotic drugs were withdrawn after admission. A diagnosis of secondary adrenal insufficiency and secondary hypothyroidism was made. Hormonal substitution with hydrocortisone and levothyroxine and correction of hyponatremia with intravenous hypertonic saline solution resulted in rapid improvement of symptoms and signs. It seems that the symptoms and signs of hypothyroidism and hyponatremia were attributed to acute psychosis in this patient. As a conclusion failure to recognize the endocrinopathy may not only produce recovery difficulties but also psychiatric and endocrine repercussions if psychotropic medications are given in such masked cases.

Sagliker syndrome: uglifying human face appearance in late and severe secondary hyperparathyroidism in chronic renal failure.

Almost every patient with chronic renal failure (CRF) eventually develops secondary hyperparathyroidism (SH) unless they are treated with proper and novel medications in advanced medical centers by skilled medical personnel. Every kind of bone abnormality including skull deformities has been described in detail by almost every concerned researcher and textbook, but descriptions of this phenomenon are limited in the medical literature to the years from 1973 to 1977. To our knowledge, extensive data regarding uglifying human face appearances have not been defined so far in the literature. We are therefore making this addition to the clinical nephrology field by accumulating such data. After we found 2 consecutive peculiar and unique patients with uglifying human face appearances in 2000, we attempted to inform and draw attention to this new entity to all hemodialysis (HD) centers in Turkey, as well as in other developing countries around the world to collect data on this phenomenon. Accordingly, we visited dialysis centers and patients' houses to collect detailed information, including medical clinical histories, physical examinations, laboratory data, biographies, current medications, and so forth. We found 25 patients who had CRF, SH, short stature, extremely severe skull changes, maxillary and mandibular bone changes, teeth/dental abnormalities, and soft and innocuous tumoral tissues in the mouth (hence, uglifying the appearance of the face), fingertip changes, severe psychologic problems, and depression. It appears that patients with CRF may have a new syndrome of bone deformities that have long been neglected, ignored, and forgotten since the mid-1970s when they were first described. This is vital and critical information for the clinical status of patients who suffered from the syndrome that we have named Sagliker syndrome (SS), and we believe there are many more patients in the world who are suffering from it.
