  • With the advent of hemodialysis, the success of renal transplants in the 1960s and the wide use of continuous ambulatory peritoneal dialysis at the end of the 1970s, children with renal failure now enjoy an extended life span. As a result, several children experience renal osteodystrophy and growth retardation. Renal osteodystrophy is induced by phosphorus retention, hypocalcemia, low vitamin D levels and hyperparathyroidism. The pharmacologic interventions are used to prevent bone deformities and to normalize growth velocity. But surgical intervention is required sometimes whorl osteodystrophy is severe and poorly controlled. We report an eight-year-old boy with ctironic renal failure who developed severe bone deformities and needed osteotomy.

  • Brown tumor is a histologically benign lesion that is a serious complication of renal osteodystrophy because it may result in severe deformity and discomfort. We report a case of brown tumor, which occurred in a 35-year-old woman with chronic renal failure, who had been treated with hemodialysis for 14 years. The lesion was found on the lingual side of the mandible. Standard panoramic radiograph showed generally decreased bone mineral density, loss of lamina dura, and thin cortical plates. Computed tomography (CT) revealed multilocular expansile lesions with heterogeneous attenuation in the anterior mandible, as well as generalized trabecular alteration with homogeneous sclerosis, and thinning or obliteration of cortical plates. Excision of the mandibular lesion and curettage of the affected bone were performed. (Korean J Oral Maxillofac Radiol 2008; 38: 229-31)

  • Renal osteodystrophy(RO) is characterized by skeletal changes in patients with renal disease and developed as a result of alterations in the metabolism of calcium, phosphate and secondary hyperparathyroidism. Bony changes in the craniofacial region include decreased bone density, radiolucent lesions(brown tumors), depletion of cortical bone and loss of lamina dura, but such changes rarely occur in the temporomandibular joint(TMJ). We report an uncommon case of bony changes and pain of both TMJs in a patient with RO. A 41-year-old man with RO came to our clinic due to TMJ pain and sounds. Occlusal change was also reported. Radiographs revealed degenerative changes of the both condyles. The patient had medical history of renal cancer therapy and hemodialysis. The patient was diagnosed with TMJ arthritis of RO and referred for systemic management through medication of calcium and vitamin D and parathyroidectomy. At 15-month follow-up, most of TMD symptoms disappeared and second radiographs revealed that bone density and cortical thickness of the mandible increased and the skeletal outline of the both condyles became relatively clear. As bony changes may begin in the early stage of the renal disease, dentists should be alert to detect the sign of the disease. In addition, it is important to differentiate TMJ arthritis of systemic cause because the treatment protocol is quite different.

  • 성장저해는 만성신부전 (chronic renal failure, CRF) 소아환자나 실험동물에게서 나타나는 합병증의 하나로, 그 발생기전이 잘 알려져 있지 않다. 성장저해를 일으키는 원인으로 비내분비적 요인 (metabolic acidosis, renal osteodystrophy, anemia)과 내분비적 요인의 복합적 결과로 생각하나, 비내분비적 요인들은 약물투여로 그 증세를 완화시켜도 성장저해에 대한 궁극적 치료효과는 나타나지 않는다. 따라서 성장 호르몬 (Growth Hormone, GH)이 관여하는 내분비적 요인의 변화에 그 병리기전이 있을 것으로 연구되어 왔다. GH는 직접적 성장 효과와 Insulin-like growth factor-1(IGF-I)을 간으로부터 유리시켜 나타나는 간접적 성장효과를 가지고 있다. 그런데 CRF환자의 GH 및 IGF-I 의 혈중 농도는 정상이거나, 흑은 오히려 증가상태에 있음에도 볼구하고 성장저해가 일어나는 것으로 보아, 환자의 말단기관 (end-organ)에 원인을 알 수 없는 저항성 (resistance)이 있다고 규정되어진다.

  • A 5-month-old intact female Siberian Husky dog was presented for evaluation of severely enlarged maxilla. Abnormalities in CBC, serum chemistry and urinalysis indicated purulent inflammation and renal failure. Cytologic examination of the swollen maxilla showed a mixed population of multinucleated giant cells and round to polygonal to spindle shaped cells either individualized or aggregated. Both type of cells showed moderate anisokaryosis, and anisocytosis, prominent nucleolus or multiple nucleoli, and coarse chromatin. On histopathology maxilla and turbinate were diffusely expanded and replaced by variably dense fibrous connective tissue, and the kidneys showed changes consistent with renal dysplasia. Based on these findings, the diagnosis of fibrous osteodystrophy due to renal dysplasia and fibrosis was made. Despite the supportive care, the dog continued to decline and was euthanized.

  • Objectives : Chronic renal failure(CRF) is a pathophysiologic process with multiple etiologies, resulting in the inexorable attrition of nephron number and function and frequently leading to end-stage renal disease. It causes various symptoms(edema, general body weakness, nausea, anorexia, uremia, osteodystrophy and so on) which impair quality of life and long term complications. The purpose of this case is to report the improvement of a patient with chronic renal failure. Methods : We treated the patient with herbal medication(Gyulpyjeonwon) and measured the creatinine, BUN, albumin, hemoglobin in the serum. Results : Gyulpyjeonwon decreased serum creatinine and BUN level and increased serum albumin and hemoglobin level. And the symptoms of CRF(edema, general body weakness, anorexia) was improved significantly. Conclusions : This case suggests the efficacy of herbal medication(Gyulpyjeonwon) to patient who was involved CRF.

  • This study aims to determine the effect of a trained dedicated dietitian on clinical outcomes among Lebanese hemodialysis (HD) patients: and thus demonstrate a viable developing country model. This paper describes the study protocol and baseline data. The study was a multicenter randomized controlled trial with parallel-group design involving 12 HD units: assigned to cluster A (n = 6) or B (n = 6). A total of 570 patients met the inclusion criteria. Patients in cluster A were randomly assigned as per dialysis shift to the following: Dedicated Dietitian (DD) (n = 133) and Existing Practice (EP) (n = 138) protocols. Cluster B patients (n = 299) received Trained Hospital Dietitian (THD) protocol. Dietitians of the DD and THD groups were trained by the research team on Kidney Disease Outcomes Quality Initiative nutrition guidelines. DD protocol included: individualized nutrition education for 2 hours/month/HD patient for 6 months focusing on renal osteodystrophy and using the Trans-theoretical theory for behavioral change. EP protocol included nutrition education given to patients by hospital dietitians who were blinded to the study. The THD protocol included nutrition education to patients given by hospital dietitian as per the training received but within hospital responsibilities, with no set educational protocol or tools. Baseline data revealed that 40% of patients were hyperphosphatemics (> 5.5 mg/dl) with low dietary adherence and knowledge of dietary P restriction in addition to inadequate daily protein intake ($58.86%{\pm}33.87%$ of needs) yet adequate dietary P intake ($795.52{\pm}366.94$ mg/day). Quality of life (QOL) ranged from 48-75% of full health. Baseline differences between the 3 groups revealed significant differences in serum P, malnutrition status, adherence to diet and P chelators and in 2 factors of the QOL: physical and social functioning. The data show room for improvement in the nutritional status of the patients. The NEMO trial may be able to demonstrate a better nutritional management of HD patients.

  • For the assessment of changes in the bone architecture of the maxilla and mandible in renal osteodystrophy, 31 chronic renal failure patients who were undergoing hemodialysis therapy were selected. They were evaluated through clinical oral examination, radiographic and biochemical examination. The results were as follows: 1. In 17 cases (54.8%), there were evidences of bony change in jawbone. 2. The most common dental radiographic finding was decreased bone density (14 cases, 45.2%). 3. The second most common dental radiographic finding was total or partial loss of lamina alveolar dura (11 cases, 35.5%). 4. The third most common dental radiographic finding was total or partial loss of inferior canal wall (8 cases, 25.8%). 5 cases showed evidences of bony change only in jawbone, and 5 cases only in hand, and 12 cases in both. 6. Serum creatinine, urea nitrogen and alkaline phosphatase values in hemodialysis group were much higher than in control group. 7. There were statistically significant correlation between bone density and lamina dura, and inferior alveolar canal wall.

  • Oligomeganephronia is a rare congenital form of bilateral renal hypoplasia histologically characterized by reduction in number and hypertrophy of nephrons. Clinically, this condition is presented in early infancy with vomiting, polyuria, polydipsia and dehydration. The problems are readily corrected, but slowly progressive renal failure follows accompanied by failure to thrive, short stature, and renal osteodystrophy. We experienced three cases of oligomeganephronia. Case 1. : A 3 2/12 years old female child was incidentally diagnosed as renal failure at age of 2 months when she was hospitalized due to pneumonia. She had open renal biopsy and was diagnosed as bilateral dysplastic kidney. On OPD follow-up, she progressed to end-stage renal failure (BUN/Cr 114/4.6 mg/dl) and had renal transplantation. The specimen was shrunk remarkably and light microscopy showed oligomeganephronia. Case 2. : A 14 8/12 years old female child with proteinuria was detected in an annual urine screening program for school children, she was diagnosed as renal failure (BUN/Cr 33.9/4.1 mg/dl), and had $5{\times}4{\times}3\;cm$ sized mass on abdominal CT scan. She had renal biopsy, and the specimen showed oligomeganephronia. She had hemodialysis for six months, and renal transplantation along with bilateral nephrectomy was performed. Case 3. : A 14 8/12 years old male child was diagnosed having chronic nephritis and chronic renal failure at 3 years old, progressed to end-stage renal failure (BUN/Cr 87/9.6 mg/dl) on OPD follow-up, and had a rephrectomy and renal transplantation. The biopsy specimen showed oligomeganephronic hypoplasia, secondary focal segmental glomerolosclerosis, and chronic interstitial nephritis. We report 3 cases of oligomeganephronia that progressed to end-stage renal failure and had successful renal transplantation with a brief review of related literatures.
