Numerous nonoperative treatments have been used to reduce pain and improve the clinical outcomes of patients with foot and ankle disorders. Among these treatments, hyaluronic acid and platelet-rich plasma (PRP) injections have been used increasingly. This review analyzes the recent literature reporting the efficacy and indications for hyaluronic acid and PRP injections. Hyaluronic acid and PRP can be used safely as adjuncts. Hyaluronic acid injections have shown efficacy and have a promising role as an adjuvant treatment method.In addition, its indication has expanded to various foot and ankle diseases over osteoarthritis. On the other hand, the efficacy of PRP injection has not yet been clarified, and the lack of standardization of procedures for the preparation and administration of PRP makes it difficult to establish definitive treatment indications.

BACKGROUND: The quality of life (QoL) of patients with end-stage renal disease (ESRD) is very poor, plausibly due to both psychosocial and medical factors. This study aimed to determine the relationship among psychosocial factors, medical factors, and QoL in patients with ESRD undergoing hemodialysis (HD). METHODS: In total, 55 male and 47 female patients were evaluated (mean age, 57.1 ± 12.0 years). The QoL was evaluated using the Korean version of World Health Organization Quality of Life Scale-Abbreviated Version. The psychosocial factors were evaluated using the Hospital Anxiety and Depression Scale, Multidimensional Scale of Perceived Social Support, Montreal Cognitive Assessment, Pittsburgh Sleep Quality Index, and Zarit Burden Interview. The medical factors were assessed using laboratory examinations. Correlation and canonical correlation analyses were performed to investigate the association patterns. RESULTS: The QoL was significantly correlated with the psychosocial factors, and to a lesser extent with the medical factors. The medical and psychosocial factors were also correlated. The canonical correlation analysis indicated a correlation between QoL and psychosocial factors (1st canonical correlation = 0.696, P < 0.001; 2nd canonical correlation = 0.421, P = 0.191), but not medical factors (1st canonical correlation = 0.478, P = 0.475; 2nd canonical correlation = 0.419, P = 0.751). The medical and psychosocial factors were also correlated (1st canonical correlation = 0.689, P < 0.001; 2nd canonical correlation = 0.603, P = 0.009). CONCLUSION: Psychosocial factors influence QoL in patients with ESRD, and should thus be carefully considered when caring for these patients in clinical practice.

Renal cortical necrosis (RCN) is a rare cause of acute renal failure in which there is a complete or partial destruction of the renal cortex with sparing of the medulla. We report here a case of acute bilateral RCN associated with intra-abdominal operation. A 70-year-old female patient was admitted to our hospital because of abdominal pain secondary to perforated diverticulits in sigmoid colon. A segmental resection of the sigmoid colon and end-to-end anastomosis was performed on the third hospital day. Two days later, she suddenly developed oligo-anuria and she was treated with hemodialysis. A contrast-enhanced abdominal computed tomography scan showed lack of enhancement of the renal cortex with enhancement of the renal medulla. On the 21th hospital day, renal biopsy was done and microscopic examination of the specimen revealed RCN. Since then, she has been on regular hemodialysis for over six months with no signs of renal recovery. Occult sepsis associated with peritonitis and intra-abdominal operation seems to be the most possible etiologic factor of RCN in our patient.

Milk-alkali syndrome (MAS), a triad of hypercalcemia, metabolic alkalosis, and renal failure, is associated with ingestion of large amounts of calcium and absorbable alkali. MAS is the third most common cause of hypercalcemia in hospital, after primary hyperparathyroidism and malignant neoplasm. MAS is not often reported in the Korean literature. We describe MAS secondary to intake of calcium citrate for the treatment of osteoporosis with thoracic spine compression fracture. A 70-year-old man presented to our hospital with a 1-week history of general weakness and lethargy. He was found with acute kidney injury (serum creatinine, 4.6 mg/dL), hypercalcemia (total calcium, 14.8 mg/dL), and alkalosis. Laboratory evaluation excluded both hyperparathyroidism and malignancy. Mental status and serum calcium level was normalized within a week after proper hydration and intravenous administration of furosemide. However, he developed aspiration pneumonia, pseudomembranous colitis, and sepsis with multi-organ failure. Despite intensive treatment including inotropics, mechanical ventilation, and renal replacement therapy, he expired with no signs of renal recovery on the 28th hospital day.

Emphysematous pyelitis (EP) is an acute bacterial renal infection characterized by the presence of gas localized to the renal collecting system, sparing the renal parenchyma. It is seen more commonly in women, often associated with underlying diabetes mellitus or obstructing stone disease. To our knowledge, EP has not been frequently reported in the Korean literature. We report here two cases of bilateral EP due to Escherichia coli in 55-year-old female and 44-year-old female patients with diabetic chronic kidney disease, were successfully treated with medical management including intravenous administration of antibiotics. Early diagnosis by means of abdominal computed tomography along with prompt antibiotic therapy may be effective in patients with bilateral EP.

Amlodipine, a calcium channel blocker of the dihydropyridine group, is commonly used in management of hypertension, angina, and myocardial infarction. Amlodipine overdose, characterized by severe hypotension, arrythmias, and pulmonary edema, has seldom been reported in Korean literature. We report on a fatal case of amlodipine intoxication with complications including rhabdomyolysis and oliguric acute kidney injury. A 70-year-old woman with a medical history of hypertension was presented at the author's hospital 6 hours after ingestion of 50 amlodipine (norvasc) tablets (total dosage 250 mg) in an attempted suicide. Her laboratory tests showed a serum creatinine level of 2.5 mg/dL, with elevated serum creatine phosphokinase and myoglobin. The patient was initially treated with fluids, alkali, calcium gluconate, glucagon, and vasopressors without a hemodynamic effect. High-dose insulin therapy was also started with a bolus injection of regular insulin (RI), followed by continuous infusion of RI and 50% dextrose with water. Despite intensive treatment including insulin therapy, inotropics, mechanical ventilation, and continuous venovenous hemodiafiltration, the patient died of refractory shock and cardiac arrest with no signs of renal recovery 116 hours after her hospital admission.

Rhabdomyolysis a clinical syndrome characterized by injury to skeletal muscle and release of intracellular contents into the systemic circulation, can develop from infections, although trauma is a more common cause. Myoglobinuric acute kidney injury (AKI) is a potentially life-threatening complication of rhabdomyolysis. Reports of rhabdomyolysis and AKI induced by salmonella infection are rare in the Korean literature. This paper describes a case of salmonella enteritis complicated by rhabdomyolysis and AKI. A 58-year-old man presented to the hospital with a two day history of watery diarrhea, abdominal pain and high fever. Initial blood chemistry revealed a serum creatinine (Cr) level of 3.4 mg/dL, with elevations of serum creatine phosphokinase (CK, 5,635 IU/L) and serum myoglobin (>3,000 ng/mL). Intravenous hydration and empirical antibiotic treatment with ciprofloxacin were initiated. Blood and stool cultures grew salmonella group B, which was sensitive to ciprofloxacin, ampicillin, and ceftazidime. Parenteral ciprofloxacin was continued for 14 days. During the first week of hospitalization, peak levels of serum Cr and CK were 9.5 mg/dL and 89,155 IU/L, respectively. Thereafter clinical and biochemical parameters gradually improved without dialysis. The patient was discharged on the 20th hospital day with normal CK levels except for serum Cr. His renal function normalized (serum Cr 1.0 mg/dL) two months after discharge. Based on the results of this case, prompt fluid therapy and early administration of antibiotics should be performed in patients with salmonella infection complicated by rhabdomyolysis and AKI.

The clinical signs of acquired hypothyroidism are usually manifested insidiously over several months to years. The incidence increases after 6 years of age and peaks at 11 to 18 years of age. The clinical symptoms and signs are fatigue, constipation, decreased growth velocity and delayed bone age, compromised intellectual performance, obesity, myxedema, hyperlipidemia, peripheral neuropathy and delayed or precocious puberty. Two children were referred to our hospital for the evaluation of severe obesity and short stature. During the evaluation we found they also had hyperlipidemia, cardiomegaly with or without pericardial effusion. Thyroid function test revealed decreased serum thyroid hormone levels with positive anti- microsome and anti-thyroglobulin antibodies consistent with long-standing acquired hypothyroidism. After the supplement of L-thyroxine, both of them showed rapid improvement of above symptoms, except for the incomplete catch-up growth. We herein report two cases of acquired hypothyroidism with severe obesity, short stature, hyperlipidemia and cardiomegaly with review of literatures.

Glucocorticoids are the most common cause of drug-induced diabetes mellitus or hyperglycemia. Hyperglycemic hyperosmolar syndrome (HHS) secondary to glucocorticoid treatment in patients with glomerular disease has rarely been reported in Korea. This paper describes a case of HHS after corticosteroid administration for the treatment of immunoglobulin A (IgA) nephropathy. A 56-year-old nondiabetic male with biopsy-proven IgA nephropathy was started on a combination therapy of an angiotensin converting enzyme inhibitor and oral prednisolone (60 mg, 0.8 mg/kg/day). Eight weeks after the initiation of steroid therapy, he was admitted with a one-week history of polydipsia, polyuria and general weakness. His laboratory tests revealed a serum creatinine level of 2.7 mg/dL, elevated blood glucose (1,221 mg/dL) and an increase in serum osmolarity (347 mOsm/kg H2O). Urinalysis showed 4+ sugars, 2+ proteins, and negative ketones. Prednisolone was tapered and he was administered with intravenous fluids, insulin and electrolytes. The patient was discharged with normoglycemia without the use of antidiabetic medications on the 18th hospital day. Patients who are taking corticosteroids for the treatment of primary glomerulopathy should be investigated for HHS promptly if they present with dehydration, general weakness and weight loss.
