Case Reports[Coronary vasospasm in a child allergic to latex: Kounis syndrome].
Kounis syndrome consists of the simultaneous occurrence of anaphylaxis and acute coronary syndrome. It is a rare entity that may be underdiagnosed in paediatrics. The clinical presentation is variable, atypical and usually unexpected, and it carries possible serious complications such as ventricular arrhythmias, myocardial infarction and sudden death. ⋯ The cardiological study ruled out coronary pathology as the cause of the event. The allergy study revealed a latex-fruit (kiwi and pineapple) cross-reactivity syndrome. The patient was diagnosed with type I Kounis syndrome triggered by latex, recommending the avoidance of possible triggers.

Case Reports[Cutaneous hyperpigmentation secondary to vitamin B12 deficiency in an infant].
Cutaneous hyperpigmentation is a rare clinical feature of vitamin B12 (cobalamin) deficiency. The cause is unknown and there are different hypothesis about the pathogenesis of the hyperpigmentation. ⋯ Based on the clinical suspicion of vitamin B12 deficiency, we performed a laboratory dosage that showed decreased levels of cobalamin, reason for which replacement therapy was indicated. It highlights the importance of the presumption of vitamin B12 deficiency as a cause of cutaneous hyperpigmentation and its rapid resolution after the establishment of the appropriate treatment.

Randomized Controlled TrialEffectiveness of magnesium sulfate as initial treatment of acute severe asthma in children, conducted in a tertiary-level university hospital: a randomized, controlled trial.
Magnesium sulfate is a calcium antagonist that inhibits bronchial smooth muscle contraction promoting bronchodilation. It is used for the management of acute severe asthma in children; however most of the studies have been performed in adults. ⋯ Intravenous infusion of magnesium sulfate during the first hour of hospitalization in patients with acute severe asthma significantly reduced the percentage of children who required mechanical ventilation support.

Review[Invasive mechanical ventilation: Update for the pediatrician].
In this review, we collect the fundamental concepts of the use of invasive mechanical ventilation (MV) in children, particularly in acute respiratory failure. MV is a common practice in the ICU and must be understood as a therapeutic intervention to replace the work of breathing while restores the balance between ventilatory demand and the patient's ability to sustain it. It is essential for the clinician to recognize that the goal of mechanical ventilatory support is not to normalize the patient's blood gases but providing a reasonable gas exchange; the benefts are obtained if the safety thresholds are not exceeded. Thus, this strategy has become the only tool available to limit the development of ventilator-induced lung injury (VILI).

Case Reports[Acute hemorrhagic edema of infancy: alarming lesions of a benign condition. Case report].
We report a case of acute hemorrhagic edema of infancy in an 18-month-old boy after an episode of otitis media. The clinical presentation begins with skin erythematous macules on the thighs, followed by purpuric lesions in arms, legs, and ankle edema. It was initially interpreted as urticaria, whereby steroids were indicated. ⋯ Differential diagnosis includes erythema multiforme, hemorrhagic urticaria, drug- induced vasculitis, Kawasaki disease, infected eczema, sepsis (either meningococcal or non-meningococcal) and child abuse. Some of them have risk of mortality. Management is conservative, however, steroids may be a therapeutic option.
