  • Drug Administration be very precise. (Standardized medicinal teaspoons and tablespoons are available.) Eye drops and nose drops (A) are designed for application to the mucosal surfaces of the eye (conjunctival sac) and nasal cavity, respectively. In order to prolong contact time, nasal drops are formulated as solutions of increased viscosity. Solid dosage forms include tablets, coated tablets, and capsules (B). Tablets have a disk-like shape, produced by mechanical compression of active substance, filler (e.g., lactose, calcium sulfate), binder, and auxiliary material (excipients).

  • The rationale for selecting three cardinal symptoms is based on their high sensitivity and their relatively high specificity for ABRS, especially when considering the time interval of persistence for 10 days or longer. 36-38 Purulent nasal drainage predicts presence of bacteria on antral aspi- ration when reported as purulent rhinorrhea by the patient, when manifest as postnasal drip or purulent discharge in the posterior pharynx, or when observed in the nasal cavity or near the sinus ostium. 39,40 Purulent rhinorrhea also predicts radiographic evidence of ABRS.

  • Approach to the Patient: Disorders of the Sense of Smell Unilateral anosmia is rarely a complaint and is only recognized by testing of smell in each nasal cavity separately. Bilateral anosmia, on the other hand, brings patients to medical attention. Anosmic patients usually complain of a loss of the sense of taste even though their taste thresholds may be within normal limits. In actuality, they are complaining of a loss of flavor detection, which is mainly an olfactory function.

  • Intensity-modulated radiotherapy (IMRT) has widened the horizons of radiation therapy due to its ability to conformradiation dose distributions to complex tumor target volumes while sparing nearby critical structures as much as physically possible. IMRT has also led to paradigm shifts in all elements of the chain of radiotherapy, from treatment prescription over treatment planning (“inverse” planning) to treatment delivery and verification.

  • Upper Respiratory Infections: Treatment Antibiotics have no role in the treatment of uncomplicated nonspecific URI. In the absence of clinical evidence of bacterial infection, treatment remains entirely symptom-based, with use of decongestants and nonsteroidal antiinflammatory drugs. Other therapies directed at specific symptoms are often useful, including dextromethorphan for cough and lozenges with topical anesthetic for sore throat. Clinical trials of zinc, vitamin C, echinacea, and other alternative remedies have revealed no consistent benefit for the treatment of nonspecific URI.

  • The maxillary sinuses are one of the four paired sets of the paranasal sinuses and the first to develop. In the second month of fetal life, an invagination forms in the lateral wall of the nasal fossa in the middle meatus (1). By the third to fourth months of fetal life, the sinus develops into a pouch and extends into the maxillary bone. At birth, it remains little more than a small sac, no more than 8 mm in length anteriorposteriorly (1, 2). Over time, these air-filled pyramid-shaped cavities extend further laterally and inferiorly as the maxilla becomes more pneumatized...
