The small airways have been neglected for many years, but interest in the topic has been rekindled with recent advances in measurement techniques to assess this region and also the ability to deliver therapeutics to the distal airways. Current levels of disease control in asthmatic patients remain poor and there are several contributory factors including; poor treatment compliance, heterogeneity of asthma phenotypes and associated comorbidities. However, the proposition that we may not be targeting all the inflammation that is present throughout the whole respiratory tree may also be an important factor. Indeed decades ago, pathologists and physiologists clearly identified the importance of small airways dysfunction in asthmatic patients. With improved inhaler technology to deliver drug to target the whole respiratory tree and more sensitive measures to assess the distal airways, we should certainly give greater consideration to treating the small airway region when seeing our asthmatic patients in clinic. The aim of this review is to address the relevance of small airways dysfunction in the daily clinical management of patients with asthma. In particular the role of small particle aerosols in the management of patients with asthma will be explored.

Plantar fasciitis is a very common cause of inferior heel pain that can be triggered and aggravated by prolonged standing, walking, running and obesity, among other factors. Treatments are largely noninvasive and efficacious. Supportive treatments, including the plantar fascia-specific stretch, calf stretching, appropriate orthotics and night dorsiflexion splinting, can alleviate plantar fascia pain. While local injections of corticosteroids can help with pain relief, the effects are short-lived and must be weighed against the risk of fat pad atrophy and plantar fascia rupture. Ultrasonography-guided focal extracorporeal shock wave therapy is useful for patients with chronic plantar fasciitis and referrals for this treatment can be made in recalcitrant cases. Activity modification to decrease cyclical repetitive loading of the plantar fascia should be advised during the treatment phase regardless of the chosen treatment modality.

Increased levels of tissue corticosteroids are associated with important protective responses of critically ill patients. Critical illness and its treatment interfere with the normal corticosteroid response to illness and induce tissue corticosteroid insufficiency. Therefore, corticosteroid is commonly used in critically ill patients. In intensive care units, the main reasons for using steroids are critical illness-related corticosteroid insufficiency (CIRCI), septic shock, acute respiratory distress syndrome (ARDS), airway edema, etc. CIRCI may be suspected due to symptoms or signs such as unconsciousness, hemodynamic instability, fever, or electrolyte imbalance. An adrenocorticotropic hormone stimulation test or measurement of a random plasma cortisol level is necessary to diagnose CIRCI. Corticosteroid administration can be helpful when CIRCI is confirmed. Similar to CIRCI, corticosteroid can be used in septic shock. However, corticosteroid administration is not recommended for patients with sepsis without shock. The use of corticosteroid in patients with ARDS is still controversial. Although steroids are commonly used for critically ill patients, there are controversies related to the use of steroids in the intensive care unit. In this article, we review the physiology of the corticosteroid response to critical illness and practical issues relating to the diagnosis and treatment of corticosteroid insufficiency in critically ill patients.

BACKGROUNDVery limited data are available on factors predictive of corticosteroids plus cyclophosphamide treatment efficacy on IgA nephropathy (IgAN). The aim of the study was to research the clinical factors predictive of treatment efficacy in IgAN.

METHODSOne hundred and fifty-nine patients with IgAN (proteinuria ≥2 g/d and estimated glomerular filtration rate 30-89 ml×min(-1)×1.73 m(-2)) were treated with corticosteroids/cyclophosphamide followed by a 12-month follow-up. According to their response, these patients were divided into remission group (proteinuria <0.5 g/d) and non-remission group (proteinuria ≥0.5 g/d), and their clinical data collected.

RESULTSIn the present study, 72.96% of the individuals underwent a complete remission, and their response was related to baseline proteinuria, urinary osmotic pressure, and renal function (P < 0.05). Patients with baseline proteinuria more than 3 g/d, urinary osmotic pressure greater than 600 mOsm/L, and eGFR 60-89 ml×min(-1)×1.73 m(-2) responded well to the combination of corticosteroids and cyclophosphamide (86.90% vs. 57.33%, P = 0.000; 81.48% vs. 64.10%, P = 0.014; 83.17% vs. 55.17%, P = 0.000).

CONCLUSIONThe response to the combination of corticosteroids and cyclophosphamide might be well associated with baseline proteinuria, urinary osmotic pressure, and renal function in patients with IgAN.

Prolonged administration of anterior hypophyseal, adrenocortical, or thyroid hormones is known to cause degeneration, degranulation and necrosis of the beta-cells in the Langerhans islets of the pancreas. However, the effects of extirpation of these endocrine glands upon the Langerhans islets has not been reported, a1though it is known that removal of any of these glands bring about hypoglycemia, decreased tissue uptake of glucose, and increased tissue sensitivity to insulin. The present investigation is studies of the morphologic alterations of the beta-cells in the Langerhans islets following hypophysectomy, adrenalectomy, or thyroidectomy in rats. Hypophysectomy, adrenalectomy, and thyroidectomy, all induce similar morphologic alterations in the beta-cells of the islets. These consist of increased beta-cell population, the accumlnation of beta-granules, and atrophy of the individual betacell. Therefore, these changes are considered to be not specific following the withdrawal of specific hormones but a common effect of the hypoglycemia due to removal of the hypophysis, adrenals, or thyroid glands. A similar common degeneration of the beta-cells due to hyperglycemia occurs when hormones of these endocrine glands are given excessively.

We report a patient with Lewis-Sumner syndrome (LSS) who showed an improvement only with plasma exchange (PE). The patient, 32-yr old man, had progressive multifocal motor-sensory deficits with persistent, multiple conduction blocks and marked slowing of NCVs. Nerve pathology supported a diagnosis of demyelinating neuropathy by revealing marked loss of myelinated fibers with inter- and intrafascicular variation. Although the patient was refractory to treatment with corticosteroid and intravenous immunoglobulin, PE produced a dramatic improvement. Our experience strongly proposes that PE should be tried for refractory LSS.

OBJECTIVETo evaluate the therapeutic effect of methylprednisolone for electrical status epilepticus during sleep (ESES) in children.

METHODThe clinical and EEG data of 82 epilepsy patients with ESES, which included benign childhood epilepsy with centro temporal spikes (BECT) variants, epilepsy with continuous spikes and waves during slow sleep (CSWS) , Landau-Kleffner syndrome (LKS) collected from department of pediatrics, Peking University First Hospital were analyzed from July 2007 to September 2012. During ESES period, all patients received methylprednisolone treatment for three courses, which included methylprednisolone intravenous infusion for three days, followed by oral prednisone for four days every time. After three courses, prednisone [1-2 mg/(kg × d)] were taken by all patients for 6 months. The ESES phenomenon and seizures were observed before and after treatment. The efficacy of corticosteroid on ESES suppression, seizure control of three epilepsy syndrome were analyzed.

RESULTThirty-nine cases were male and 43 cases were female. The epilepsy syndromes included 49 patients diagnosed as benign childhood epilepsy with centrotemporal spike (BECT) variants, 27 patients diagnosed as epilepsy with continuous spikes and waves during slow sleep (CSWS), and 6 patients diagnosed as LKS. Age of onset ranged from 1 year and 4 months to 11 years. The age of ESES newly monitored was from 2 years to 10 years and 8 months. The total effective rate of corticosteroid was 83% (68/82) for ESES, BECT variants was 82% (40/49), CSWS was 81% (22/27), LKS was 100% (6/6). There was no statistically significant difference in effective rates between the front two (χ² = 0.09, P > 0.05). The seizures were improved in the first month after methylprednisolone treatment in 3 epilepsy syndromes. The recurrence rate of BECT variants was 47% (23/49) , CSWS was 59% (16/27) , LKS was 50% (3/6) after 1 year follow up. There was no association between disease parameters, including age at seizure onset, duration of ESES and the treatment effect of ESES examined by Kruskal-Wallis method (χ² = 3.585, 0.932, P > 0.05).

CONCLUSIONMethylprednisolone was effective for improving ESES and seizures in 3 epilepsy syndromes combined with ESES. There was no significant correlation between age at seizure onset, duration of ESES and treatment effect of ESES.

OBJECTIVETo examine serum concentration of interleukin-18 (IL-18) and IL-18 mRNA expression in peripheral blood mononuclear cells (PBMCs) in children with primary nephrotic syndrome (PNS) and explore the possible role of IL-18 in steroid-resistant nephrotic syndrome (SRNS).

METHODSSixty-six children with newly diagnosed PNS, including 39 cases of steroid sensitive nephrotic syndrome (SSNS) and 27 cases of SRNS, were enrolled. Forty healthy children were used as a normal control group. Blood samples were collected before and 8 weeks after glucocorticoid treatment. Serum concentration of IL-18 was measured using ELISA. IL-18 mRNA expression in PBMCs was detected by the RT-PCR method. The amount of 24-hr urine protein was measured by the biuret method. Serum contents of total cholesterol (T-Ch), triglyceride (TG), low density lipoprotein (LDL), total protein (TP), and albumin (Alb) were measured by the automatic biochemistry analyzer.

RESULTSSerum concentration of IL-18 and IL-18 mRNA expression in PBMCs in the SSNS and the SRNS groups were significantly higher than those in the normal control group before treatment (P< 0.05). The SRNS group had increased serum protein concentration of IL-18 and IL-18 mRNA expression in PBMCs compared with the SSNS group before treatment (P< 0.05). Serum LDL content in the SRNS group was also significantly higher than that in the SSNS group before treatment (P< 0.05). After treatment, serum concentration of IL-18 and IL-18 mRNA expression in PBMCs in the SRNS group were significantly higher than those in the SSNS and the normal control groups (P< 0.05). Serum concentration of IL-18 and IL-18 mRNA expression in PBMCs in the SSNS group were significantly reduced after treatment, but the alterations of IL-18 were not observed in the SRNS group after treatment.

CONCLUSIONSSRNS was associated with increased serum IL-18 concentration and IL-18 mRNA expression in PBMCs. Over-production of IL-18 may play a role in the development of SRNS.

PURPOSE: We undertook an observational study to investigate the effects of immunosuppressive treatment on proteinuria and renal function in 179 Korean idiopathic membranous nephropathy patients with nephrotic syndrome. MATERIALS AND METHODS: The primary outcome was regarded as the first appearance of remission and the secondary outcomes as a decline in estimated glomerular filtration rate (eGFR) >50% or initiation of dialysis, and all-cause mortality. Seventy-two (40.2%) and 50 (27.9%) patients were treated with corticosteroids alone (C) and corticosteroids plus cyclosporine (C+C), respectively, whereas 57 (31.8%) did not receive immunosuppressants (NTx). Cyclosporine was added if there was no reduction in proteinuria of >50% from baseline by corticosteroids alone within 3 months. RESULTS: There were no differences in baseline renal function and the amount of proteinuria among the three groups. Overall, complete remission (CR) was achieved in 88 (72.1%) patients by immunosuppressants. In a multivariate analysis adjusted for covariates associated with adverse renal outcome, the probability of reaching CR was significantly higher in the C [hazard ratio (HR), 4.09; p<0.001] and C+C groups (HR, 2.57; p=0.003) than in the NTx group. Kaplan-Meier analysis revealed that 5-year CR rates of C, C+C, and NTx groups were 88.5%, 86.2%, and 56.7% (p<0.001). Ten-year event-free rates for the secondary endpoints in these three groups were 91.7%, 79.9%, and 57.2% (p=0.01). CONCLUSION: Immunosuppressive treatment was effective in inducing remission and preserving renal function in these patients. Therefore, stepwise treatment using corticosteroids alone and in combination with cyclosporine is warranted in these patients.
