Background: The administration of antenatal corticosteroids (ACS) is standard practice for management of threatened preterm birth. Its benefit, especially in small for gestational age (SGA) late preterm, is unclear.

Objectives: To evaluate the impact of ACS on perinatal outcome of late preterm SGA neonates.

Methods: We conducted a retrospective cohort study of all women carrying a singleton gestation who had late preterm delivery (34–36 gestational weeks) of SGA neonates at a single tertiary university-affiliated medical center (July 2012–December 2017). Exclusion criteria included termination of pregnancy, intrauterine fetal death, and birth weight ≥ 10th percentile. Outcomes were compared between ACS and non-ACS treatment prior to delivery. Neonatal composite outcome included neonatal intensive care unit (NICU) admission, respiratory distress syndrome, mechanical ventilation, and transient tachypnea.

Results: Overall, 228 women met inclusion criteria; 102 (44.7%) received ACS and 126 did not (55.3%). Median birth weight among the non-ACS group was significantly higher (1896.0 vs. 1755.5 grams P < 0.001). Rates of NICU and jaundice requiring phototherapy were higher among the ACS group (53.92% vs. 31.74%, P = 0.01; 12.74% vs. 5.55%, P = 0.05, respectively). Composite neonatal outcome was significantly higher among the ACS group (53.92% vs. 32.53%, odds ratio [OR] 2.42, 95% confidence interval [95%CI] 1.41–4.15, P = 0.01). After adjustment for potential confounders, this association remained significant (OR 2.15, 95%CI 1.23–3.78, P = 0.007).

Conclusions: ACS given during pregnancy did not improve respiratory outcome for SGA late preterm neonates. ACS may be associated with a worse outcome.

Background: Although 5-amino-salycilic acids (5-ASA) are often used with corticosteroid treatment in moderate-to-severe ulcerative colitis, the value of continuing/initiating 5-ASA in this clinical setting has not been explored. 

Objectives: To investigate the impact of a combination 5-ASA+corticosteroid therapy on the outcome of hospitalized patients with acute moderate-severe ulcerative colitis. 

Methods: We conducted a retrospective study of patients hospitalized with moderate-severe ulcerative colitis in two centers, Israel and South Korea. Patients were classified into those who received 5-ASA and corticosteroids and those who received corticosteroids alone. Analysis was performed for each hospitalization event. The primary outcome was the rate of treatment failure defined as the need for salvage therapy (cyclosporin-A/infliximab/colectomy). The secondary outcomes were 30 days re-admission rates, in-hospital mortality rates, time to improvement, and length of hospitalization. 

Results: We analyzed 209 hospitalization events: 151 patients (72%) received 5-ASA+corticosteroids and 58 (28%) corticosteroids alone. On univariate analysis the combination therapy group had a lower risk for treatment failure (11% vs. 31%, odds ratio 0.28, 95% confidence interval 0.13–0.59, P = 0.001). However, this difference disappeared on multivariate analysis, which showed pre-admission oral corticosteroid treatment to be the most significant factor associated with the need for salvage therapy. 

Conclusions: A signal for possible benefit of a combination 5-ASA and corticosteroids therapy was found, but was confounded by the impact of pre-admission corticosteroid treatment. 

 

Background: Intraarticular injections for the local treatment of osteoarthritis are widely used in the office or hospital setting. Septic arthritis is a potential catastrophic complication of intraarticular injection, as bacterial arthritis of any cause is associated with up to 15% mortality and residual impairment of joint function in up to 50% of survivors. There is lack of evidence regarding the precautions that should be taken to avoid such a complication, as well as how often it is encountered.

Objectives: To report our experience with the clinical presentation, diagnosis and treatment of knee septic arthritis following intraarticular injections. 

Methods: We followed six patients who were admitted to the hospital and underwent surgery for the treatment of pyogenic arthritis following injection to the knee joint in outpatient clinics.

Results: All but one patient were over 70 years old with comorbidities. Three patients were injected with steroid preparations and three with hyaluronic acid several days before admission. In all six patients the infection was treated surgically and three of them had undergone more than one operation during their hospitalization. Four of the six patients were treated by means of an open arthrotomy and synovectomy, and the other two were treated successfully with arthroscopic lavage and synovectomy. One patient underwent an above-knee amputation due to septic shock and died after several days.

Conclusions: Despite the rarity of this complication, surgeons must be aware of the possibility of pyogenic arthritis when administering injections, especially in elderly patients with serious underlying medical conditions.

Background: There are several treatment options for simple bone cysts, with treatment depending mainly on the experience and preference of the surgeon and the extension and location of the cyst.

Objectives: To assess our experience with the surgical treatment of bone cyst lesions in pediatric patients at one institution by the same group of surgeons.

Methods: The study group comprised 60 patients (43 boys, 17 girls) treated surgically for monostatic lesions between January 2002 and July 2007. The mean age at surgery was 11.8 years (range 4–17 years). Mean follow-up was 4.2 years. Most of the lesions were located at the proximal humerus. Patients were divided into five groups according to treatment method: a) corticosteroids (methylprednisolone 40-80 mg) (n=26); b) curettage and bone grafting (fibula or iliac crest) (n=16); c) aspiration of the bone cavity and subsequent bone marrow transplantation (n=10); d) internal preventive fixation using an elastic stable intramedullary nail (n=5); and e) curettage and implantation of a synthetic cancellous bone substitute (pure beta-tricalcium phosphate substitute, ChronOS®, Synthes, Switzerland) (n=3).

Results: Treatment success was evaluated by the Capanna criteria. Successful results were observed in 68% (18 complete healing, 23 healing with residual radiolucent areas), 30% recurrence rate, and no response to treatment in one patient (2%). We recorded recurrence in 50% of the children treated by corticosteroid injection, and one child did not respond to treatment.

Conclusions: The best results were achieved in children treated by curettage and the subsequent use of an osteoconductive material, and in children treated with elastic intramedullary nail fixation. Despite our limited experience with calcium-triphosphate bone substitute, the treatment was mostly successful. Because of the short follow-up, further observation and evaluation are necessary.

Sepsis is an inflammatory syndrome caused by infection. Consequently, anti-inflammatory therapies in sepsis have been a subject of extensive research and corticosteroids have been used for years in the therapy of severe infections. However, studies conducted in the 1980s failed to demonstrate any beneficial effects of high dose, short-term steroid therapy in sepsis and this therapy was therefore abandoned during the last decade. Recently, a new concept has emerged with more promising results - low dose, long-term hydrocortisone therapy – and this approach is now being evaluated in the treatment of septic shock. It is supported by the observation that many sepsis patients have relative adrenal insufficiency. Moreover, the anti-inflammatory effects of steroids and their ability to improve reactivity to catecholamines further contribute to their effects in sepsis. Large randomized clinical trials will be required to determine the exact role of corticosteroids in septic shock.

Background: Nitrofurantoin is a commonly prescribed urinary antiseptic. Hepatic injury has been associated with its use.

Objectives: To present three patients in whom long-term exposure to the drug resulted in chronic active hepatitis, and review the epidemiology, clinical immunology, histopathology, pathogenetic features and treatment of previously reported cases.

Findings: Withdrawing nitrofurantoin once the diagnosis was suspected did not lead to remission of the liver disease and glucocorticoids had to be administered. One patient died of liver failure.

Conclusions: Awareness of this unusual side effect of nitrofurantoin is important and caution should be exerted before prescribing it. Over the past years new insight into the immune nature of this drug has emerged.
 

Background: About one-third of patients with severe ulcerative colitis do not respond to conventional therapy and require urgent colectomy. It was recently shown that cyclosporin is effective in some of these patients.

Objectives: To review the current experience of six hospitals in central Israel that used cyc-losporin in patients with severe ulcerative colitis.

Methods: The files of all 32 patients treated with cyclosporin for corticosteroid-resistant ulcerative colitis were reviewed. Activity of disease was measured by a clinical activity, index colonoscopy and laboratory tests.

Results: The average duration of treatment with intravenous cyclosporin was 12.7 days (range 9–28) after which the disease activity index dropped from an average of 14.22 to 4.74. The mean time for response was 7.5 days (4–14). Twelve patients (40%) required surgery within 6 months and another 6 patients (18.8%) were operated on after more than 6 months. Twelve patients (37%) maintained remission for at least 6 months and did not require surgery. In one patient treatment was stopped because of non-compliance and one was lost to follow-up. There were numerous side effects, but in only one case with neurotoxicity was treatment withdrawn.

Conclusions: Cyclosporin is a relatively safe and effective treatment for severe ulcerative colitis. It induced long-term remission in 37% of the patients, and in those who required surgery the treatment resulted in an improved clinical condition before the operation.
