Pneumococcal Mastoiditis in Children Before and After the Introduction of Conjugate Pneumococcal Vaccines.

Objectives: To determine whether serotype distribution and antibiotic resistance of Streptococcus pneumoniae acute mastoiditis (AM) in children have changed in the post pneumococcal conjugate vaccines (PCVs) era.

Methods: Medical records of pneumococcal AM cases, in a tertiary pediatric hospital were reviewed from January 1999 to December 2014. S.

Pneumatosis cystoides intestinalis after cetuximab chemotherapy for squamous cell carcinoma of parotid gland.

Pneumatosis intestinalis, defined as gas in the bowel wall, is often first identified on abdominal radiographs or computed tomography (CT) scans. It is a radiographic finding and not a diagnosis, as the etiology varies from benign conditions to fulminant gastrointestinal disease. We report here a case of pneumatosis intestinalis associated with cetuximab therapy for squamous cell carcinoma of head and neck.

A meta-analysis on the effectiveness of propranolol for the treatment of infantile airway haemangiomas.

Objective: To study the effectiveness of propranolol in infantile airway haemangiomas and compare the effectiveness of propranolol vs. different therapies.

Methods: A literature search of Ovid, Embase, the Cochrane database, Google™ Scholar, and Medline using PubMed as the search engine was performed to identify studies that analysed the effect of propranolol treatment in children with airway haemangiomas.

Carbonic anhydrase-9 expression in head and neck cancer: a meta-analysis.

The purpose of the study was to compare CA-9 positivity versus CA-9 negativity in head and neck malignancies and to correlate levels of CA-9 with tumor grade, size, and nodal status. Overall and disease-free survival were also compared for CA-9 positive and negative tumors. A literature search was performed using Medline, Embase, Ovid and Cochrane databases for studies between 1990 and 2009.

PFAPA syndrome in children: A meta-analysis on surgical versus medical treatment.

Objective: To compare the range of medical and surgical therapies for children with PFAPA syndrome.

Methods: A literature search was performed using Medline, Embase, Ovid and Cochrane databases for studies between 1987 and 2010 that compared PFAPA treatment in children (surgical versus medical). Random-effect meta-analytical techniques were conducted for the outcome measures.

Foreign bodies of the ear and nose in children and its correlation with right or left handed children.

Objective: Foreign bodies (FB) of the ear and nose are common findings in the pediatric population. The objective of this project is to present our experience of cases presented to our department and to correlate the insertion of the FB in relation to the child's handedness.

Methods: This project was carried out at the Department of Otorhinolaryngology Head and Neck Surgery of "Aghia Sophia" Children's Hospital (Athens, Greece), between December 2007 and August 2008.
