Estimates are that only 15% of young patients with frontal sinus fractures resulting from automobile accidents were wearing a seatbelt; less than 10% of patients with frontal sinus fractures from motorcycle accidents were wearing a helmet treatment 1860 neurological order 0.5 mg avodart. The use of helmets with motorcycles symptoms 6 days past ovulation order 0.5mg avodart, bicycles medications an 627 proven avodart 0.5 mg, at appropriate sporting events symptoms 5 weeks pregnant cramps trusted 0.5 mg avodart, and in industrial situations also can protect the frontal sinuses. The influence of airbag and restraining devices on the patterns of facial trauma in motor vehicle collisions. Patients who are conscious at the time of the evaluation typically report frontal pain. Other less common signs on physical examination 282 Pathogenesis Motor vehicle accidents are the most common mechanism of injury for patients with frontal sinus fractures, accounting for 60­70% of all frontal sinus fractures. Assault typically requires the use of a blunt object to fracture the frontal sinus; fists alone rarely generate sufficient force. Other mechanisms of injury include industrial accidents, recreational accidents, and gunshot wounds. Young men in their third decade of life are most at risk for frontal sinus fracture. In one study, 30% of patients with frontal sinus fractures had blood Copyright © 2008 by the McGraw-Hill Companies, Inc. Between 5% and 10% of patients have no significant physical findings on examination. Other facial fractures occur in up to 95% of patients; bones of the orbit and paranasal sinuses are the most commonly involved. Intracranial injuries are seen in approximately 50% of patients; of these types of injuries, frontal contusions are the most common. Axial and direct coronal images using 3-mm cuts and bone windows are typically used for the evaluation of frontal sinus fractures. Soft tissue windows should be used to evaluate intracranial and orbital injuries, which are often seen in patients with frontal sinus trauma. In these patients, 1-mm axial cuts with reformatted coronal images represent a viable alternative. X-rays-The role of plain x-ray films in the evaluation of frontal sinus fractures is limited. In patients with nonoperative fractures and fluid in their frontal sinuses, serial Caldwell views may be used to monitor resolution of the fluid, insuring patency of the frontonasal recess. A high index of suspicion for posterior table fractures is necessary in all patients. In patients with frontal sinus fractures, the frontonasal recess is the most difficult area to evaluate. When evaluating a frontal sinus fracture, it is important to assess the future function of the frontonasal recess. Serial imaging studies may be considered in select patients in whom reliable follow-up is likely. In isolated anterior wall fractures, involvement of the frontonasal recess is rare. Patients with anterior wall fractures and associated supraorbital rim or nasoethmoid complex fractures have associated frontonasal recess injury in 70­90% of cases. Combined anterior and posterior wall fractures are also commonly associated with injury to the frontonasal recess. More severe complications include mucoceles, severe persistent pain, and infectious intracranial complications. Such complications are uncommon, with a reported rate of 6% for meningitis and mucocele formation and 1% for severe pain and brain abscess. Chronic sinusitis, mild chronic pain, and diplopia (ie, double vision) are significantly less common. All of these complications, particularly mucoceles, may not manifest until years after the original injury. With the evaluation of the extent of the injury and appropriate treatment, complications from frontal sinus fractures can be limited.

On examination there is diffuse abdominal tenderness and a rash over the arms and the legs. A 68-year-old woman presents to the emergency department with altered mental status. A renal biopsy specimen is obtained and reveals a focal proliferative glomerulonephritis, characterized by linear staining of the basement membrane on immunofluorescence for IgG. He is subsequently found to have an eye tumor that is caused by dysfunction of a specific cell-cycle regulatory gene product. Acute allograft rejection is mediated by cytotoxic T-lymphocytes that recognize and are activated by the major histocompatibility complex proteins expressed by the donated organ. A depleting monoclonal antibody to which of the following cell surface molecules would be most useful in reducing this immune-mediated graft rejection? A 67-year-old former landscaper is referred to the dermatologist for a lesion on his right forearm. A 24-year-old man presents to the emergency department with hypertension, tachycardia, fever, diaphoresis, mydriasis, and severe agitation. When asked, his mother states that her son and his friends "probably used some drugs they got in the neighborhood. A 64-year-old man with a history of hypertension, coronary artery disease, and type 2 diabetes presents to his physician because he "has trouble seeing. A 28-year-old woman with a past medical history significant for pelvic inflammatory disease presents to the emergency department with right lower quadrant abdominal pain. The pain began two hours ago, has been consistently localized to the right lower quadrant without migration, and has been associated with nausea and vomiting. Although her periods are usually regular, her last menstruation was approximately six weeks ago. On examination, she is found to be afebrile with a blood pressure of 90/60 mm Hg, a pulse of 110/min, and a respiratory rate of 26/min. Abdominal examination shows localized tenderness with guarding in the right lower quadrant. Pelvic examination is deferred due to excessive pain, but vaginal bleeding is noted. Physical examination reveals an elevated jugular venous pressure, crackles, and 4+ pitting edema bilaterally. Her oncologist believes her chemotherapeutic agent is responsible for these complaints. A 22-year-old woman comes to your office complaining of vaginal itching and burning. She says she feels as if she "has the flu" and has had intermittent fevers and muscle aches over the past few days. Vaginal examination reveals the lesion seen in the image, and treatment is started. The patient subsequently develops elevated levels of blood urea nitrogen and creatinine in addition to a tremor and mental status changes. A 33-year-old man from upstate New York comes to his physician because of flu-like symptoms after a camping trip one week ago.

Movement of the basilar membrane up and down treatment efficacy generic 0.5 mg avodart, induced by sound waves within the cochlear fluids 2 medications that help control bleeding effective avodart 0.5 mg, causes a shearing force to deflect the hair cell stereocilia treatment urinary incontinence purchase avodart 0.5mg. Passive filtering produces a traveling wave in response to sound vibrations (Figure 44­22) symptoms 14 days after iui effective 0.5 mg avodart. The location of the peak of the traveling wave changes with the frequency of the sound played into the ear. The change in location results from the tonotopic organization of the organ of Corti. There are systematic differences in its mass and stiffness along its length that determine the frequency response at any specific location. At the base of the cochlea (the high-frequency region), it has a lower mass and a higher stiffness. In contrast, at the apex of the cochlea (the low-frequency region), the organ of Corti has a higher mass and a lower stiffness. Sound vibrations that enter the cochlea at the stapes footplate propagate along the length of the cochlear duct and are maximal when they match the characteristic frequency at a specific location. Active Processes within the Cochlea Analyses of the cochlea based only on passive mechanical properties such as mass and stiffness cannot explain the exquisite frequency selectivity of human hearing or the frequency selectivity that could be measured from individual auditory nerve fibers. However, the frequency selectivity of the cochlea can be enhanced if a source of mechanical energy is present in the cochlea. The concept that a source of mechanical energy exists in the cochlea appeared validated when in the late 1970s it was discovered that sound is produced by the inner ear. They were called otoacoustic emissions, and they are now routinely measured in the clinic to assess hearing. The function of the outer hair cell in hearing is now perceived as that of a cochlear amplifier that refines the sensitivity and frequency selectivity of the mechanical vibrations of the cochlea. The outer hair cell must be more than flexible; it must also be strong enough to transmit force to the rest of the organ of Corti. The outer hair cell has reinforced its membrane with a highly organized actin-spectrin cytoskeleton just underneath the plasma membrane (Figure 44­23). The shape of the outer hair cell is maintained by a pressurized fluid core that pushes against an elastic wall. The wall is reinforced by additional layers of cytoskeletal material and membranes. The lateral wall of the outer hair cell is about 100 nm thick and contains the plasma membrane, the cytoskeleton, and an intracellular organelle called the subsurface cisternae. The cytoskeleton consists of actin filaments that are oriented circumferentially around the cell and that are cross-linked by spectrin molecules. Outer Hair Cells the organ of Corti is a highly organized sensory structure that sits on the basilar membrane (see Figure 44­17). There is a single row of inner hair cells, and there are three rows of outer hair cells. These rows of hair cells run the length of the cochlea and are positioned on top of the basilar membrane by various supporting cells. There are tight junctions between the apex of the hair cells and the surrounding supporting cells that form the barrier (the reticular lamina) between the endolymph and the perilymph. Pressurization of the Outer Hair Cells Most cells have a cytoskeleton to maintain cell shape. Because such an internal skeleton would impede electromotility, a central cytoskeleton is missing in the cylindrical portion of the outer hair Plama membrane Cytoskelton Particles Subsurface cisternae Extracisternal space Pillar Axial core Spectrin Actin Cuticular plate Figure 44­23. They vary in length from approximately 12 µm at the basal or high-frequency end of the cochlea to > 90 µm at the low-frequency end. Their diameter at all locations is approximately 9 µm, which is slightly larger than the diameter of a red blood cell. Their apical end is capped with a rigid flat plate into which the stereocilia are embedded, and their synaptic end is a hemisphere (compare with the typical hair cell shown in Figure 44­11). Each of these three regions (flat apex, middle cylinder, and hemispheric base) has a specific function. The stereocilia at the apex of the cell are responsible for converting the mechanical energy of sound into electrical energy. Synaptic structures are found at the base of the hair cell and are responsible for converting electrical energy into chemical energy by modulating the release of neurotransmitters.

The linea semilunaris runs parallel with the lateral border of the rectus sheath and is a prominent landmark for surface anatomy treatment anal fissure quality avodart 0.5 mg. The upper right quadrant is the correct anatomic region for the location of the gallbladder as mentioned earlier; however medications on backorder proven 0.5 mg avodart, this choice is too general and would not be the best answer choice treatment variable proven 0.5mg avodart. Similarly symptoms night sweats buy 0.5mg avodart, the intersection of the right semilunaris with the right intertubercular plane is situated in the upper right quadrant; however, this is not the most precise location of the gallbladder. The contents of the epigastric region are the left portion of the liver and a portion of the stomach. The right hypochondriac region, the anatomic region situated to the right of the epigastric region, is located superior and lateral to the gallbladder and would thus not be the appropriate answer choice. Veins of the body wall and veins of the retroperitoneal intestinal organs are interconnected by extensive, thin-walled, anastomosing vessels. Ascites is the accumulation of such fluid in the peritoneal cavity from these collateral veins. Ascites can occur within the veins of the body wall or veins of the retroperitoneal organs. An anastomosis between the epigastric veins and the paraumbilical veins would lead to possible contribution to caput medusae but would not likely result in significant ascites. Esophageal varices are due to expansion of submucosal esophageal veins from portal hypertension, resulting from anastomoses between the left gastric vein and the esophageal veins. These anastomoses would produce varices, perhaps with profuse bleeding, rather than ascites. Superior rectal, left gastric, and the middle rectal veins all contribute to the portal-systemic anastomoses, but these anastomoses form varices or hemorrhoids, not ascites. The portal vein would not lead to ascites because it is not involved directly with any caval anastomoses. The transversus abdominis aponeurosis and transversalis fascia form a significant portion of the posterior wall of the inguinal canal and the lower part of the inguinal triangle (of Hesselbach). Gradual weakness or attrition of tissues in the posterior wall provides the likelihood of egress of a direct inguinal hernia. A patent processus vaginalis at the deep inguinal ring, or expansion of the deep inguinal ring, with stretching of the transversalis fascia there, can contribute to the formation of indirect inguinal hernias. Weakness of the transversalis fascia by itself is not a key feature of inguinal herniation, nor is weakness of the peritoneum, or defects in the aponeuroses of the external or internal oblique muscles. The rectouterine pouch (of Douglas) is the lowest recess of the female abdominopelvic cavity when the woman is standing or sitting upright. Any fluid accumulation in this cavity will settle in the rectouterine pouch due to it being the most dependent or inferior space. The subphrenic space would likely not collect fluid because of its location in the superior abdominal cavity, which does not tend to collect fluid from the pelvis. The hepatorenal pouch (of Morison) is located in the right posterosuperior aspect of the abdominal cavity, far from the pelvic cavity. The vesicouterine space is a recess that is similarly located in the lower portion of the abdomen between the urinary bladder and uterus, but it is slightly superior to the pouch of Douglas and separated from it and the pathway of the leaking fluid by the broad ligament of the uterus. The broad ligament tends to prevent the collection of fluids in the vesicouterine pouch. The dorsal root ganglia contain all cell bodies of sensory neurons from the body wall and limbs. The sympathetic chain contains postganglionic sympathetic cell bodies that are targeted to smooth muscle and glands of the viscera and heart muscle. The greater splanchnic nerve (T5 to T9) carries preganglionic sympathetic axons to the celiac ganglion, which is formed by postganglionic sympathetic neurons. The lateral horn of the spinal cord is found in levels T1 to L2 and contains preganglionic sympathetic cell bodies. The preganglionic sympathetic fibers running to the adrenal gland would be cut during adrenalectomy for they synapse on catecholamine-secreting cells within the adrenal medulla. Unlike the normal route of sympathetic innervation, which is to first synapse in a sympathetic ganglion and then send postganglionic fibers to the target tissue, the chromaffin cells of the adrenal gland are innervated directly by preganglionic sympathetic fibers. This is because the chromaffin cells are embryologically postganglionic neurons that migrate to the medulla and undergo differentiation. The adrenal gland receives no other recognized types of innervation; therefore, the remaining answer choices are all incorrect. Compression of the vein in this location is a frequent cause of deep venous thrombosis of the left lower limb; that is, the venous drainage of the lower limb is obstructed.

Answer A is not the best answer because this lump is described as soft and pliable medicine administration purchase 0.5 mg avodart, which would not likely indicate a tumor symptoms 7 weeks pregnancy safe avodart 0.5mg, as tumors tend to be hard masses medications known to cause weight gain purchase avodart 0.5mg. This question tests anatomic knowledge relating to typical vertebrae and the spinal cord medicine disposal cheap 0.5mg avodart. Intervertebral disk herniations occur when the nucleus pulposus of the intervertebral disk protrudes through the anulus fibrosus into the intervertebral foramen or vertebral canal. The most common protrusion is posterolaterally, where the anulus fibrosus is not reinforced by the posterior longitudinal ligament. The inferior and superior vertebral notches frame the intervertebral foramen, so this is the most likely location of compression. The denticulate ligaments are lateral extensions of pia mater that anchor to the dura mater, and they hold the spinal cord in position within the subarachnoid space. The vertebral foramen is the canal through which the spinal cord passes; while this may also be a place of compression, it is not the most likely site of herniation. Articular facets are the locations where vertebral bodies articulate with each other. Intercostovertebral joints are locations where vertebral bodies articulate with ribs. Caudal anesthesia is used to block the spinal nerves that carry sensation from the perineum. This procedure is commonly used by obstetricians to relieve pain during labor and childbirth. Administration of local anesthetic to the epidural space is via the sacral hiatus, which opens between the sacral cornua. The anterior sacral foramina are located on the pelvic surface of the sacrum and are not palpable from a dorsal approach. The posterior sacral foramina and intervertebral foramina are the openings through which sacral nerves exit and are not palpable landmarks. The sacral cornua lie on either side of the sacral hiatus, from which one can gain access to the sacral canal. The ischial tuberosities are more commonly used as landmarks for a pudendal nerve block. The posterior superior iliac spines, though palpable, are not proximal enough for an epidural block within the sacral canal. The suprascapular nerve passes through the suprascapular notch, deep to the superior transverse scapular ligament. This nerve is most likely affected in a fracture of the scapula as described in the question. The axillary nerve passes posteriorly through the quadrangular space, which is distal to the suprascapular notch. The subscapular nerve originates from the posterior cord of the brachial plexus, which is distal to the site of fracture. Klippel-Feil syndrome is a congenital defect in which there is a reduction, or extensive fusion, in the number of cervical vertebrae. Spondylolisthesis is an anterior vertebral displacement created by an irregularity in the anterior margin of the vertebral column such that L5 and the overlying L4 (and sometimes L3) protrude forward rather than being restrained by S1. Herniation is a protrusion of the nucleus pulposus through the anulus fibrosus, and this is not associated with vertebral dislocation. Arnold-Chiari malformation results from herniation of the medulla and cerebellum into the foramen magnum. Tethered cord syndrome is a congenital anomaly caused by a defective closure of the neural tube. This syndrome is characterized by a low conus medullaris and a thick filum terminale. Spondylolisthesis is an anterior displacement created by an irregularity in the anterior margin of the vertebral column such that L5 and the overlying L4 (and sometimes L3) protrude forward.
