Parastomal hernia is one of the most common complications after colostomy. Preventive strategies are considerable. For less defect and better mechanical work in abdominal wall, extraperitoneal colostomy is preferred for preventing parastomal hernia. In this work, we demonstrated a new surgery technique through anatomy structures and mechanical principles

The diagnosis of long QT syndrome may be delayed due to ab sence of electrocardiogram (ECG) examination and/or QT interval misdiagnosis. We present the case of a patient who took 8 years before being diagnosed with long QT syndrome. Despite the pres ence of marked QT prolongation and bimodal T waves, automated ECG recording misdiagnosed the patient to be normal. The patient had recurrent syncope; however, repeat ECG examination was not performed because her initial ECG was considered normal.

The interpretation of the acid-base status is key in medical practice, being its most frequent use in critically ill pregnant patients with any type of hemodynamic alteration such as hemorrhagic shock or septic shock, which happens in most cases, states of hypoperfusion systemic that produce alteration in the acid base state that gener ates primary disorders such as acidemia or alkalemia and its met abolic or respiratory components. We make an approach through an arterial or venous blood gas analysis, which has the advantage of an evaluation in a short time to be a diagnosis and thus take medical conduct for a better management of the pregnant patient.
