  • Radiographically, the floor of the maxillary sinus appears as a thin radiopaque line (1). If there is little pneumatization of the alveolar process, the floor of the sinus may be seen superior to the roots of the maxillary posterior teeth, or it may not be visible on periapical radiographs. If the maxilla is extensively pneumatized, the floor of the sinus will appear to drape around the roots of the teeth or be superimposed over the roots of the teeth, giving the appearance of the roots penetrating the sinus floor. In these cases, the lamina dura of maxillary posterior teeth...

  • 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...

  • Harrison's Internal Medicine Chapter 84. Head and Neck Cancer Head and Neck Cancer: Introduction Epithelial carcinomas of the head and neck arise from the mucosal surfaces in the head and neck area and typically are squamous cell in origin. This category includes tumors of the paranasal sinuses, the oral cavity, and the nasopharynx, oropharynx, hypopharynx, and larynx. Tumors of the salivary glands differ from the more common carcinomas of the head and neck in etiology, histopathology, clinical presentation, and therapy. Thyroid malignancies are described in Chap. 335.

  • Orbital Cellulitis This causes pain, lid erythema, proptosis, conjunctival chemosis, restricted motility, decreased acuity, afferent pupillary defect, fever, and leukocytosis. It often arises from the paranasal sinuses, especially by contiguous spread of infection from the ethmoid sinus through the lamina papyracea of the medial orbit. A history of recent upper respiratory tract infection, chronic sinusitis, thick mucous secretions, or dental disease is significant in any patient with suspected orbital cellulitis. Blood cultures should be obtained, but they are usually negative.

  • Microbiology S. aureus is a pathogen in more than half of cases of contiguous-focus osteomyelitis. However, in contrast to hematogenous osteomyelitis, these infections are often polymicrobial and are more likely to involve gram-negative and anaerobic bacteria. Hence a mixture of staphylococci, streptococci, enteric organisms, and anaerobic bacteria may be isolated from a diabetic foot infection or pelvic osteomyelitis underlying a decubitus ulcer.

  • 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.

Evidence on the operational advantages of providing triple ARVs to all HIV-infected pregnant women (Options B and B+), on how to best meet the programme requirements of these approaches, and on the acceptability, effectiveness and prevention impact of providing lifelong ART to all HIV-infected pregnant women (Option B+) will help inform upcoming guidelines revision.

  • Adequate illumination of the TM requires proper lighting and an open ear canal, but cir- cumstances are seldom optimal. As many as one-third of physicians treating AOM have reported changing otoscope bulbs less often than recommended, and in one-third of oto- scopes the light output has been inadequate (Barriga et al. 1986). Children’s narrow ear canals are easily obstructed by cerumen, which compromises visualization. Cerumen removal is necessary in about 30% of children with AOM, and even more often in infants (Schwartz et al. 1983).
