Tratamiento quirúrgico para hematoma subcapsular hepático posterior a colangiografía retrógrada endoscópica; caso inusual

BACKGROUND Even in expert hands, there can be serious complications when performing an endoscopic retrograde cholangiopancreatography. The most frequent complications are pancreatitis, cholangitis, bleeding, perforation, and acute cholecystitis. The hepatic subcapsular haematoma is a rare complication, with few cases described worldwide. OBJECTIVE A case is presented of an extremely rare complication of endoscopic retrograde cholangiopancreatography, which required surgical treatment for its resolution without success. This is second case of mortality reported in the literature. CLINICAL CASE Female patient of 30 years old, with indication for endoscopic retrograde cholangiopancreatography due to benign strictures. A hydro-pneumatic dilation and stent placement of 2 gauge 10 fr was performed. She presented abdominal pain after the procedure and significant decline in haemoglobin with no evidence of haemodynamic instability so an abdominal tomography scan was performed, showing no evidence of liver injury. The patient was haemodynamic unstable within 72 h. A laparotomy was required for damage control, with fatal outcome in the intensive care unit due to multiple organ failure. CONCLUSION Subcapsular hepatic haematoma after endoscopic retrograde cholangiopancreatography is a rare complication, with few cases reported in the literature. Treatment described in the literature is conservative, resulting in a satisfactory resolution.

Treatment for Gynaecomastia in Men. Experience with the Inferior Periareolar Incision in a Single Third Level Medical Facility

Background: Gynaecomastia is defined as an enlargement of the mammary gland in men. Objective: To evaluate Aesthetic Results of Subdermal Mastectomy by means of Inferior Periareolar Incision. Materials and Methods: Descriptive, cross sectional and prospective study. We evaluate aesthetic results of Subdermal Mastectomy by means of Inferior Periareolar Incision using Analog visual Scale applied by an another Surgeon) and a Questionnaire (Auto Evaluation). Variables: Age, Clinical Symptoms, Evolution time, Complications and Aesthetic Results. Descriptive and Inferencial Statistic was used (Wilcoxon test).

Efficiency in bracket bonding with the use of pretreatment methods to tooth enamel before acid etching: sodium hypochlorite vs. hydrogen peroxide techniques

Bond failures are produced by the existence of biofilm on the tooth surface. Because biofilm is impermeable, it prevents contact in many areas, reducing the etching effect which selectively dissolves calcified tissues but does not seem to eliminate biofilm from the tooth surface, and thus the bond between the tooth and the bracket is not strong enough. The aim of this study is to compare bracket bonding efficiency with two dental surface pretreatments: sodium hypochlorite vs. hydrogen peroxide techniques. This was a cross-sectional, comparative, in vitro study. Seventy-five premolars extracted for orthodontic purposes were evaluated. They were divided into three groups of 25 teeth and assigned randomly toone of the pretreatment techniques (5.25%sodium hypochlorite or 3.5% hydrogen peroxide) or to a control group. The most efficient pretreatment technique for bonding to brackets was sodium hypochlorite, with an average of 17.15 (kg/F). Significant differences were observed between groups (p=0.0001). The post hoc bond strength test showed statistically significant differences between the sodium hypochlorite technique and the control group (p=0.0001). The sodium hypochlorite technique improves bracket adhesion to tooth enamel.
