RESUMEN
The objective of the present study was to develop a sequential sampling plan for the decision-making process to control Tenuipalpus heveae Baker (Acari: Tenuipalpidae), an important pest of the rubber tree crop. The experimental area was represented by 1,000 plants of the RRIM 600 clone divided in 100 plots with 10 plants each. Leaves were collected and the number of mites determined under laboratory conditions. The sequential sampling plan was developed in accordance with the Sequential Test Likelihood Ratio. The value 0.10 was pre-established for α and ß representing type I and type II errors, respectively. The level of control adopted was six mites per 12 cm(2). The operating characteristic curve and the curve of maximum expected sample were determined. Two lines were generated: the upper one, when the condition for chemical control is recommended (S1 = 23.3080 + 2.1972); and the lower, when chemical control is not recommended (S0 = -23.3080 + 2.1972). Sample size for the decision-making process to control T. heveae requires 6 to 18 plants.

Angioneurotic oedema is an acute swelling involving the submucosal or subcutaneous tissues; it is most often located in the oral and maxillofacial region, which can result in upper airway obstruction. Its aetiology is frequently associated with immunoglobulin-mediated hypersensitivity reactions that elicit a heightened inflammatory response. The objective of this study was to report the case of a patient who developed an episode of angioneurotic oedema following combined orthognathic surgery. Pharmacological and nonpharmacological interventions used in the treatment of this important clinical condition are described and discussed.

Temporomandibular joint (TMJ) pseudoankylosis is characterized by limited mouth opening and mandibular movements, resulting from factors outside the joint. The authors present a case of TMJ pseudoankylosis caused by congenital zygomatic malformation and hyperplasia of the coronoid process. Treatment with coronoidectomy and postoperative physiotherapy achieved favorable results.
