Steroid induced bone loss is a serious problem in frequently relapsing nephrotic syndrome especially in growing children. In order to evaluate whether $1-(OH)D_3$ (IL Sung Pharma.Co.) is effective in preventing steroid induced bone loss, we gave $0.5{\mu}g$ of $1-(OH)D_3$ for one year to forty patients with frequently relapsing nephrotic syndrome, receiving longterm prednisolone therapy (mean duration $50.12{\pm}29.40$ months). We checked the following markers before and after $1-(OH)D_3$ therapy. i.e. bone mineral density(BMD) using dual energy X-ray absorptiometry(DEXA) at the 2nd to 4th lumbar spine, serum calcium, phosphorus, parathyroid hormone(PTH), osteocalcin and urine pyridinoline(U-PYD). BMD($g/cm^2$) was increased even steroid therapy from $0.71{\pm}0.0\;to\;0.73{\pm}0.0$ (p<0.05). Lumbar spine BMD is a sensitive marker for evaluating steroid induced bone loss in children receiving longterm corticosteroid therapy and that $1-(OH)D_3$ appears to be effective in treating and preventing steroid induced bone loss.

In South Korea, attempted suicide by paraquat (PQ) intoxication is fairly common, and is lethal by pulmonary fibrosis and hypoxemia. However, the treatment of PQ poisoning is primarily supportive management. To increase the survival rate associated with PQ intoxication, many treatments have been developed. Here, we treated a case of PQ intoxication with steroid pulse therapy. A 23-year-old man was admitted to the hospital because of PQ intoxication. He drank two mouthfuls of Gramoxon (24% commercial paraquat). His vital signs were stable, but he had a throat infection, and navy blue urine in the sodium dithionite test. Standard treatment, including gastric lavage with activated charcoal was performed, and emergent hemoperfusion with a charcoal filter was initiated 11 h after PQ ingestion. Pharmacotherapy was initiated 18 h after PQ ingestion with the administration of 5 mg dexamethasone. On day 10, chest PA showed pulmonary fibrosis. Therefore, we initiated steroid pulse therapy, with 1g methylprednisolone in 100 mL of D5W administered over 1 h repeated daily for 3 days, and 1 g cyclophosphamide in 100 mL of D5W administered over 1 h daily for 2 days. On day 15, dexamethasone therapy was initiated. On day 30, pulmonary fibrosis was improved. Thus, if pulmonary fibrosis becomes exacerbated after dexamethasone therapy during the subacute stage, pulse therapy with methylprednisolone and cyclophosphamide could be helpful.

Objective : Craniopharyngiomas (CPs) are associated with hypothalamic damage that causes hypothalamic obesity, however, the mechanisms underlying CP-related postoperative weight gain remain debatable. This study aimed to elucidate whether the major determinant of postoperative weight gain in patients with CP is hypothalamic injury or steroid replacement therapy. Methods : We included 48 adult patients with CP (age ≥18 years) who underwent transsphenoidal surgery between 2010 and 2018 in a single tertiary center, and whose body weight was measured pre- and postoperatively (<120 days after the surgery). We recruited 144 age- and body mass index-matched patients with non-functioning pituitary adenoma (NFPA) as controls. Results : Patients with CP experienced greater postoperative weight gain than patients with NFPA (3.0±5.1 vs. 0.1±3.6 kg, p<0.001). The prevalence of postoperative steroid use was significantly higher in patients with CP than in those with NFPA (89.6% vs. 34.0%, p<0.001). Steroid replacement therapy and CP were associated with postoperative weight gain after adjusting for covariates in overall patients (p=0.032 and 0.007, respectively). In subgroup analysis with postoperative steroid users, weight gain was significantly greater in patients with CP (n=43, 0.96±0.25 kg/month) than in patients with NFPA (n=49, 0.26±0.23 kg/month) even after adjusting for the daily steroid dose (p=0.048). Conclusion : Patients with CP experience greater postoperative weight gain than those with NFPA. Hypothalamic damage itself as well as steroid replacement may contribute to the postoperative weight gain in patients with CP.

Objective: To find out clinical features and long-term outcomes of idiopathic childhood nephrotic syndrome(NS) patients with late steroid resistance(LSR)/late steroid sensitiveness(LSS). Patients and Methods: A retrospective chart review was performed on 480 patients diagnosed with idiopathic childhood NS at Asan Medical Center Children's Hospital from 1990 to 2013. Twenty-four patients whose responsiveness to steroids changed over a minimum 2 year follow-up period (2-17.5 years) were investigated. All patients had undergone a renal biopsy. Results: Among 480 nephrotic children, 428 (89%) were sensitive to the first steroid course. Of those who initially responded, 11 (2.5%) developed resistance to steroid therapy after relapses. LSR mostly developed between 1 month and 1 year after the initial episode. Six patients showed a minimal change and five showed focal segmental glomerulosclerosis (FSGS). Nine (82%) responded to cyclosporine or methylprednisolone pulse therapy. Of these, two had no further relapse, whereas the other seven experienced several relapses that ranged in length from 1.1 to 13.9 years. Three of the nine who initially responded to immunosuppression went on to experience several changes in steroid responsiveness. Two (18%) with resistance to immunosuppressants, including steroids, eventually progressed to end stage renal disease. Among the 52 patients (11%) who were initially steroid resistant, 13 (23%) were converted to steroid sensitive at relapses. Among these, 9 showed minimal change and 4 showed FSGS. Two had no further relapse and the other 11 responded to steroids on subsequent relapses ranging in length from 1.3 to 9.4 years. All these patients have had no further changes in steroid responsiveness with normal renal function. Conclusions: In this study, 2.5% of initial steroid responders and 25% of initial steroid non-responders changed their responsiveness to steroids at subsequent relapses. Eighteen percent of LSR patients developed end stage renal disease. All of the LSS patients showed preserved normal renal function. Responsiveness to immunosuppressants seemed to be the most important factor determining longterm outcomes in LSR/LSS patients.

Chronic granulomatous disease (CGD) is an inherited immunodeficient disease characterized by recurrent infections and granuloma formation. Granulomatous obstruction of esophagus is one of the rare complications of CGD. The use of steroids and antimicrobials for esophageal obstruction by granuloma in CGD patients has been controversial due to the possibility of concomitant inapparent infection. We report a case of esophageal obstruction in an 8-year-old CGD patient showing the poor response to antibiotics therapy. However, dramatic improvement of symptoms and radiologic findings of esophageal obstruction were achieved after steroid therapy. One month after discontinuation of steroid, esophageal obstruction recurred and the patient was re-treated with steroid. After that time, he experienced one more recurrence of esophageal obstruction. This symptom subsided after antibiotics therapy without steroid and he has been followed up to the present without further relapse.

Purpose: Pyoderma gangrenosum is a rare inflammatory, reactive dermatosis marked by painful cutaneous ulcer. The causes of pyoderma gangrenosum remain unclear. Gastrointestinal, hematological, rheumatological, and immmune disorders may be associated with pyoderma gangrenosum. The appearance of this disease may range from mild skin ulcers to life-threatening conditions. Generalized multiple ulcerative pyoderma gangrenosum is very rare. Here we report our experience with a case of multiple ulcerative pyoderma gangrenosum accompanied by ulcerative colitis. Methods: A 67-year-old man had cutaneous ulcers at multiple sites including the scalp, face, chest, abdomen, hands, and buttocks. He also developed gastrointestinal symptoms such as intermittent dyspepsia and bloody excrement. Debridement and irritation aggravated the disease progress. We gave a diagnosis of pyoderma gangrenosum with ulcerative colitis based on the clinical appearance and biopsy. The patient was treated with systemic intravenous steroid therapies and careful wound cares. Ulcers of the scalp and buttocks were treated with split thickness skin grafts. Results: Most of the multiple cutaneous ulcers were treated by systemic intravenous steroid therapies and wound cares. The rest of the ulcers were treated with skin grafts. Systemic intravenous steroid therapy was used to treat the ulcerative colitis. Conclusion: Generalized multiple ulcerative pyoderma gangrenosum is very rare. Without making an accurate diagnosis, hasty surgical treatments could aggravate the progression of the disease. Additionally, care should be taken to systemically treat underlying disease as well as administrating local treatments for the skin lesions. Intravenous systemic steroid therapy and skin grafts are useful treatments for generalized pyoderma gangrenosum.

Purpose : $Henoch-Sch\ddot{o}nlein$ Purpura(HSP) is a self-limited systemic small vessel vasculitis, however, renal involvement is considered to contribute to the outcome of this disease. Therefore, identifying the renal risk factors in HSP and prevention of renal involvement are important. The aim of this study is to investigate whether early steroid administration in HSP could reduce the rate of renal involvement. Methods : We retrospectively studied two hundred children with HSP. We had administrated steroids orally to resolve of severe abdominal pain, joint and scrotal symptoms. We analyzed the relationship between the steroid therapy to relieve systemic symptoms and the subsequent renal involvement in HSP. Results : There were no significant differences in the incidence and duration of renal involvement according to steroid administration and its duration. In HSP patients with renal manifestations, steroid administration group showed a tendency of hematuria and steroid non-administration group showed a tendency of proteinuria, however, we could not find statistically significant differences in each group. There was no significant difference in the duration of purpura presence according to steroid administration. However, persistent purpura increased the incidence and the duration of renal involvement. Conclusion : Early steroid administration did not reduce the risk of renal involvement, there-fore, steroid could not prevent delayed nephritis in children with HSP On the other side, Persistent Purpura, known to be not related to steroid therapy, was associated with renal involvement. We suggest that early steroid administration could not be useful in preventing the renal involvement in HSP. (J Korean Soc Pediatr Nephrol 2007;11:185-194)

Background: Epidural steroid therapy has been well-established for the treatment of sciatica and low back pain. Disappointing results following surgical decompression or discectomy have led to wide trials of corticosteroids injected either systemically or into the intraspinally. Although epidural steroid is known to be very effective in the treatment of the patients with low back pain, few data showed the therapeutic duration of epidural steroid. Methods: We studied 120 patients who were treated with epidural steroid for the treatment of low back pain or sciatica or both. We retrospectively analysed the duration of analgesia, number of injections per each session, and complications. Results: The duration of analgesia ranged from 17 days to 300 days, and the mean duration was $73.7{\pm}70.5$ (SD) days. The mean number of injections per each session was $1.8{\pm}1.3$ (range: 1 to 12). There were no significant complications with epidural steroid injections. Conclusions: One to three epidural steroid injections at one week interval leads more than two months of pain relief without significant complications.

A 7.1 kg, seven-year old, castrated male, Shih-Tzu with severe pruritus, chronic otitis externa and Malassezia infection was referred to Veterinary Medical Teaching Hospital of Chungnam National University. In local animal hospital, steroid therapy was used to treat uncontrollable pruritus, but the clinical signs were recurrent when steroid therapy was discontinued. On physical examination, generalized alopecia, erythema, papules, severe crust and diffuse lichenification were presented. Tape strip test of skin lesions revealed cocci and Malassezia infections. Based on the result of history, clinical signs and examination described above, canine atopic dermatitis with secondary superficial pyoderma and Malassezia dermatitis was diagnosed. Oral challenge with cyclosporine and antibiotics had good results in clinical signs. Clinical sign scores were evaluated by investigator with CADESI at 2weeks, 4weeks, 6weeks, 8weeks and 10weeks after cyclosporine administration. And in the result of comparing of allergen-specific IgE value, the level of allergen-specific IgE to general causative allergen after 10 weeks of cyclosporine therapy was higher than that before cyclosporine therapy.
