Amounts of methylprednisolone in breastmilk are very low. No adverse effect have been reported in breastfed infants with maternal use of any corticosteroid during breastfeeding. With maternal intravenous doses of methylprednisolone 1 gram, fully breastfed infants would receive doses less than their daily cortisol output, and much less than a therapeutic dose on the day of infusion; accumulation of the drug does not occur in breastmilk with 3 consecutive daily doses. Avoiding breastfeeding during the infusion for as little as 2 hours after a 1 gram intravenous dose would markedly reduce infant exposure. Breastfeeding abstinence for 2 to 4 hours would further reduce the infant dose. Local injections, such as for tendinitis, would not be expected to cause any adverse effects in breastfed infants, but might occasionally cause temporary loss of milk supply.

Methylprednisolone sodium succinate (MPSS) has been suggested as a treatment for spinal cord injury (SCI), but its use has been limited due to its adverse effects. Erythropoietin (EPO) has been suggested as a promising candidate for limiting SCI in mammals. The aim of the present study was to investigate the effects of EPO in combination with MPSS on astrocytes following ischemic injury in vitro. Astrocytes were isolated from the cerebral cortex of postnatal day 3 Sprague‑Dawley rats and cultured in vitro. Astrocyte ischemic injury was induced by oxygen and glucose deprivation for 4 h, and reperfusion was simulated by subsequent culture under normoxic conditions. The effects of EPO and MPSS on the expression of aquaporin‑4 (AQP4) were investigated. Ischemic astrocytes were treated with EPO (10 U/ml), MPSS (10 µg/ml), or EPO (10 U/ml) in combination with MPSS (10 µg/ml) during reperfusion. The cell viability of astrocytes was assessed using an MTT assay. The mRNA and protein expression levels of AQP4 were determined using reverse transcription‑quantitative polymerase chain reaction and western blot analysis, respectively. The role of the protein kinase C (PKC) signaling pathway in the molecular mechanisms underlying the effects of EPO and MPSS was also investigated. The present results demonstrated that following treatment with EPO and MPSS, the mRNA expression levels of AQP4 were upregulated and cell viability was enhanced. EPO and MPSS effectively inhibited the oxygen and glucose deprivation‑mediated downregulation of AQP4 following reperfusion. In addition, the combined treatment with EPO and MPSS exhibited higher AQP4 expression levels and cell viability compared with each treatment alone. Finally, the effects of EPO and MPSS on AQP4 expression were partially reversed by pretreatment with the PKC inhibitor Ro 31‑8220. The present study indicated that EPO and MPSS had a synergistic effect on AQP4 expression following reperfusion, and suggest that they may be combined in the treatment of SCI.

Rapid improvement of tick-borne encephalitis after treatment with corticosteroids Tick-borne encephalitis (TBE) is a viral disease transmitted by ticks. The virus is divided into three subtypes named Western, Siberian and Far Eastern TBE virus (TBEV). Western TBEV is endemic in parts of Europe and Sweden and typically causes a biphasic illness with influenza-like symptoms followed by neurological symptoms ranging from mild meningitis to severe meningoencephalitis and death. Despite an effective vaccine, TBE is increasing in Sweden and Europe. The pathogenesis of TBE is poorly understood; direct infection of neurons as well as immunological reactions mediated by T-cells have been implicated. In some endemic areas, such as Lithuania, patients with TBE are given corticosteroids based on the clinical experience that it results in rapid improvement. However, existing retrospective studies have failed to show beneficial effects of corticosteroids compared to symptomatic treatment in patients with TBE. This case report describes how an elderly man with meningoencephalitis and cranial nerve palsy due to TBE  rapidly improved after administration of high dose corticosteroids.

Cicatricial Pemphigoid is a subepithelial bullous dermatosis which essentially involves the mucous membranes with cicatricial evolution We report the case of a 66-year old patient hospitalized with erosive gingivitis associated with dysphagia, dyspnea and blurred vision. Dermatologic examination showed erosive lesions involving the palate and the pharynx. Ophthalmologic examination showed symblepharons, ectropion and bilateral cataract. Gingival biopsy revealed a necrotic detachment of the buccal epithelium. Direct immunofluorescence showed linear IgA deposit at the dermo-epidermal junction. Indirect immunofluorescence test was negative. The diagnosis of cicatricial pemphigoid was confirmed. Esophagogastroduodenoscopy objectified double stenosis of the esophagus. Nasopharyngeal and bronchial endoscopy showed ulceration of the epiglottis, hypopharynx, pharynx and bronchial tree. The patient was treated with Solumedrol bolus corresponding to 0.5mg/kg/day prednisone associated with 100mg/day disulone. The patient showed a favorable early clinical outcome complicated because of the aggravation of dysphagia and esophageal stenosis after 2 months. Our case study is singular due to the occurrence of a cicatricial pemphigoid in a male patient with a serious clinical picture due to lesions extending to conjunctival, oral, nasal, esophageal and bronchial mucous membranes associated with direct immunofluorescence only showing IgA deposit.

Anaphylaxis is defined as a serious allergic or hypersensitivity reaction in the most cases as a result of an IgE-mediated allergic reaction that is rapid in onset and may cause death. Common triggers are foods, insect stings, and medications. The medical treatment includes, epinephrine, glucocorticoids, antihistamines and inhaled bronchodilators, with the aim to prevent progression to life-threatening respiratory and/or cardiovascular symptoms.
