Six patients were occupationally exposed to high concentrations of methyl bromide during a fumigation procedure using adequate airway protection. Within a few hours all patients developed skin lesions, consisting of sharply demarcated erythema with multiple vesicles and large bullae. There was a striking predisposition for parts of the skin that were relatively moist or subject to mechanical pressure, such as axillae, groin, and abdomen. Microscopically, early skin lesions revealed necrosis of keratinocytes, severe edema of the upper dermis, subepidermal blistering, and diffuse infiltration of neutrophils and, to a lesser degree, eosinophils. Two patients developed an urticarial rash approximately one week after the exposure. On histologic examination, these late lesions showed combined features of a spongiotic dermatitis and urticaria. No immunopathologic manifestations were observed. In all patients, the skin returned to normal after four weeks, except for some residual hyperpigmentation. Plasma bromide levels after exposure strongly suggested percutaneous absorption of methyl bromide.

Aside from the more traditional methods of treating bronchial asthma, it has been the purpose of this review to consider some of the ancillary modes of therapy and to decide if they have a place in clinical practice. Regarding antihistamines, there is little evidence to support their therapeutic use in the management of asthma, but there is strong evidence for their safety in the treatment of allergic rhinitis or urticaria in asthmatic patients. Iodides have been used for years, but there is no good body of evidence to demonstrate their effectiveness. While they may be helpful in rare cases, one must be fully aware of their potential side effects and toxicity. Mucolytic agents induce bronchospasm and for the present should be contraindicated in asthma management. Of all ancillary modes of therapy, the anticholinergic agents seem the most promising. This is based on the theory of cholinergic mechanisms in asthma production as well as some clinical trials supporting this efficacy. Many of the problems of inhaled atropine have been eliminated with the development of atropinelike anticholinergic agents such as ipratropium bromide and oxytropium but unfortunately, none of these has been approved as yet for use in the United States.

Irritable bowel syndrome (IBS) is a disease of unclear, complex pathophysiology characterised by abdominal pain and discomfort and altered bowel activity. It affects an estimated 10-15% of individuals worldwide and has a large impact on quality of life (QOL) and both direct and indirect healthcare costs. Symptoms of IBS are usually triggered by disruption of gastrointestinal (GI) function secondary to infection, dietary factors, lifestyle changes or psychological stress. While most currently available pharmacological treatments of IBS focus on symptomatic treatment of the syndrome, agents that attempt to address the pathophysiology of the disease, in particular the role of serotonin, have received much attention in recent years. However, there is growing concern that serotonergic agents as a class may be associated with rare, but serious, episodes of ischaemic colitis, with several cases of this complication having been reported in association with use of serotonergic agents that have reached the market. Thus, there remains an important need for safe and effective agents that treat the symptoms of IBS. Otilonium bromide, a spasmolytic agent, has been widely used worldwide and has been found to be effective and safe for managing abdominal pain. Clinical trials indicate that it improves baseline abdominal pain and distension, and is particularly effective in reducing diarrhoea. Combining otilonium bromide with benzodiazepines, such as diazepam, may improve the efficacy of the agent with respect to GI symptoms, while also treating underlying anxiety disorders. More research is required to confirm the efficacy and mechanisms of action associated with this combination therapy in IBS. Safety data from clinical trials and postmarketing sources indicate that otilonium bromide is well tolerated, with a safety profile comparable to placebo in clinical trials and only two reported cases of adverse reactions (urticaria) among 10-year postmarketing data. This article reviews the pathophysiology and treatment of IBS with a particular focus on the role of otilonium bromide in the management of this condition.

Perioperative anaphylaxis is characterized by severe respiratory and cardiovascular manifestations. Correct management of anaphylaxis during anaesthesia requires a multidisciplinary approach with prompt recognition and treatment of the acute event by the attending anesthesiologist. A 34-year-old woman was scheduled to undergo endo venous laser therapy of varicose veins. She had no history of allergies and had never undergone general anesthesia. General anesthesia was induced with propofol and rocuronium bromide. Approximately three minutes after rocuronium administration, hypotension and tachycardia developed and angioedema around the eyelids and skin rashes and urticaria appeared. The patient received ephedrine and hydrocortisone with hydration. After achieving stable vital signs and symptom relief, surgery was performed without complications. A postoperative skin dermal test performed to identify the agent responsible revealed a positive skin test for rocuronium.

Opioid free anesthesia (OFA) is deffined as anaesthesiological technique where opioids are not used in the intraoperative period (systemic, neuroaxial or intracavitary). Anaphylaxis caused by opioids (fentanyl) is very rare, and the reaction is presented with hypotension and urticaria. When we have proven allergy to fentanyl, patients' refusal of placing epidural catheter and refusal of receiving bilateral ultrasound guided transversus abdominis plane block (USG TAPB), we must think of using multimodal nonopioide analgesia. The concept of multimodal balanced analgesia is consisted of giving different analgesic drugs in purpose to change the pathophysiological process which is included in nociception, in way to receive more effective intraoperative analgesia with less adverse effects. This is a case report of a 60-year-old male patient scheduled for laparotomic hemicolectomy, who previously had proven allergy to fentanyl. We have decided to give him an opioid free anaesthesia. Before the induction to anaesthesia, the patient would receive dexamethasone (dexasone) 0.1 mg/kg and paracetamol 1 gr intravenously. The patient was induced into general endotracheal anesthesia according to a standardized protocol, with midazolam 0.04 mg/kg, lidocaine hydrochloride 1 mg/kg, propofol 2 mg/kg and rocuronium bromide 0.6 mg/kg. Anaesthesia was maintained by using sevoflurane MAC 1 in order to maintain mean arterial pressure (MAP) with a value of +/- 20% of the original value. After tracheal intubation, the patient had received ketamine hydrochloride 0.5 mg/kg (or 50 mg ketamine) in bolus intravenously and a continuous intravenous infusion with lidocaine hydrochloride (lidocaine) 2 mg/kg/hr and magnesium sulfate (MgSO4) 1,5 gr/hr. At the end of surgery the continuous intravenous infusion with lidocaine and magnesium sulfate was stopped while the abdominal wall was closed and 2.5 g of metamizole (novalgetol) was given intravenously. VAS score 2 hours after surgery was 6/10 and 1 gr of paracetamol was given and the patient was transferred to the Department. Over the next 3 days, the patient had a VAS score of 4-6/10 and only received paracetamol 3x1g and novalgetol 3x1 gr daily, every four hours.
