Patients with grass pollen allergy, commonly called pollinosis, often present reactivity to pollen allergens from a number of grass species due to cross-reactivity of IgE antibodies to pollen proteins present in pollen grasses. In this context, Italian rye grass (Lolium multiflorum) pollen of the Poaceae family cultivated in Southern Brazil has been considered a major sensitizing agent in patients with pollinosis. In this region, Italian rye grass is capable of producing a great amount of pollen. ⋯ Pollen extracts derived from homologous or heterologous grasses are often used for both diagnosis and treatment of seasonal allergy. However, no standardized L. multiflorum pollen extract is commercially available in Brazil and mixed grass extracts are commonly used for diagnosis and immunotherapy of grass pollen allergy. Further studies are required to better characterize the cross-reactivity between L. multiflorum and other grass pollen allergens for improving the diagnosis and immunotherapy to L. multiflorum pollen allergy.

Intraoral and transcutaneous cervical ultrasound in the differential diagnosis of peritonsillar cellulitis and abscesses.
The objective of the present study was to determine the specificity, sensitivity and accuracy of intraoral and transcutaneous ultrasound (US) in the diagnosis of peritonsillar cellulitis and abscess. ⋯ Intraoral US was quite sensitive in the diagnosis of peritonsillar abscesses when performed by an experienced radiologist. Specificity was higher for transcutaneous US compared to intraoral US. However, when transcutaneous US was performed in patients with trismus, it was able to diagnose all peritonsillar abscesses, since they were large collections which are common in patients with trismus. These exams showed similar accuracy.

Profile of hospitalizations due to otorhinolaryngologic morbidity requiring surgical treatment. Brazil, 2003.
To analyze the profile of the surgical procedures related to otorhinolaryngology in Brazil in the year 2003. ⋯ Knowledge about the profile of surgical hospitalizations related to ORL permits the identification of the peculiarities of the different regions that can help health-managing authorities to make decisions in order to guarantee the principles recommended by SUS regarding access to health services.

Review[Obstructive sleep apnea and hypopnea syndrome: cephalometric analysis].
Obstructive sleep apnea and hypopnea syndrome (OSAHS) are characterized by repeated pauses in breathing during sleep, usually associated with sleep interruption and decreased oxyhemoglobin saturation. Cephalometric analysis has become an important method in diagnosis, reporting specific craniofacial characteristics such as posterior air pharyngeal space, tongue length and hyoid position, which may predispose some people to develop SAHOS. The purpose of this revision is to present several anatomic aspects by cephalometric analysis that may have a predisposition to the development of upper airway occlusion.

Case ReportsOnset of subcutaneous emphysema and pneumomediastinum after tonsillectomy: a case report.
Several complications can be related to surgical approaches of head and neck regions. Among those, there are rare conditions such as pneumomediastinum, pneumothorax and subcutaneous cervical emphysema. This study reports a case of a patient that developed pneumomediastinum, pneumothorax and subcutaneous emphysema after undergoing tonsillectomy. In order to reduce these complications in surgical approaches such as tonsillectomy, care should be taken with intubation, use of oxygen mask for positive pressure ventilation during anesthesia recovery, aggressive surgical maneuvers and use of surgical instruments that may cause deep tonsillar injuries.
