Anatomy/distribution The cell bodies of the motor neurons are located in the spinal cord. Their axons emerge as rootlets anterior to the dorsal roots of the cord (C1-6), and form a trunk that extends rostrally and laterally to the foramen magnum and posterior to the vertebral artery to enter the posterior cranial fossa. The trunk joins with fibers of the vagus nerve, then separates from them within the jugular foramen. Outside the jugular foramen, the nerve passes posteriorly and medially to the styloid process, then descends obliquely to enter the upper portion of the sternocleidomastoid muscle. The nerve crosses the posterior triangle of the neck, closely associated to lymph nodes. Above the clavicle it passes the deep anterior border of the trapezius to supply this muscle. Symptoms Damage to the accessory nerve may cause shoulder pain of variable severity, paresthesias over shoulder and scapula, weakness of the shoulder, and a dropped shoulder. Signs Lesion causes weakness of head rotation to the opposite side, and trapezius weakness that results in inability to lift the shoulder and raise the arm above horizontal. Pathogenesis Intracranial part: Topographical lesions Rare, intracranial tumors. At the jugular foramen: Lesions occur in association with the glossopharyngeal and vagus nerves – Vernet’s syndrome, local tumors, Schwannomas, metastasis. Sarcoidosis, Siebmann syndrome, Collet Siccard syndrome. Injury to the neck: Biting Blunt trauma Carotid endarterectomy Coronary bypass surgery Radiation Shoulder blows Shoulder dislocation Stretch/hyperextension injury Variant of neuralgic amyotrophy Neoplastic: ENT tumors, metastasis at the base of the skull, Collet Siccard syndrome, spinal tumors. Iatrogenic: Surgery in the neck (posterior cervical triangle), deep cervical lymph node extirpation. Sternocleidomastoid muscle: Diagnosis Difficulty with head rotation. Trapezius muscle: Upper, middle and lower parts of the trapezius muscle must be examined separately. Upper and middle part lesions may produce winging of the scapula (Upper part- in contrast to lower part when caused by serratus anterior dysfunc- tion) Test: Abduct the arm through 180 ° from its resting position. The trapezius muscle is responsible for the upper 90 ° of movement above shoulder level. NCV: Stimulation of the nerve at the posterior aspect of the sternocleidomas- toid muscle. EMG: sternocleidomastoid, trapezoid upper, middle, and lower parts. Acute idiopathic onset may resemble acute brachial plexopathy. Therapy No operation is effective in long standing scars. Further expoloration is warranted if no improvement occurs after closed trauma. References Hunter CR, Dornette WHL (1972) Neurological injuries in the unconscious patient.

Because the skin is such a large organ and exhibits changes in response to so many elements in the internal and external environ- Mary Jo Goolsby ments discount 5gm bactroban with mastercard acne 4 week old baby, the list of skin disorders is extensive buy bactroban 5gm overnight delivery acne map. For this reason, this chapter is organized to provide information to assist providers in making a definitive diagnosis for most common conditions. Information is provided on these common conditions and on some less-common mimics, to assist the reader in applying the content in a practical manner. HISTORY General Integumentary History When patients present with complaints related to the skin, there is an inclination to immediately examine the skin, as the lesion or change is often so readily observable. However, it is crucial that cli- nicians obtain a history before proceeding to the exam, so that they understand the background of the problem. A thorough symptom analysis is essential and should include details regarding the onset and progression of the skin change; anything the patient believes may trigger, exacerbate, or relieve the problem; how it has changed since ﬁrst noticed; and all associated symptoms, such as itching, malaise, and so on. When a patient has a skin complaint, it is important to 12 Copyright © 2006 F. Skin 13 include a wide range of other integumentary symptoms in the review of systems. For instance, ask whether the patient has recently experienced any of the following: dryness, pruritus, sores, rashes, lumps, unusual odor or perspiration, changes in warts or moles, lesions that do not heal, or areas of chronic irritation. Establish whether the patient has noticed any changes in the skin’s coloration or texture. Determine what the patient believes caused or contributed to the problem, any self-treatment and the response, and any distress caused by the complaint. Even minor and self-limited skin problems can cause a great amount of anxiety owing to their visibility and their uncomfortable symptoms, such as burning, oozing, or itching. Past Medical History The past medical history should include details on any previous dermatologic illnesses. Ask about infectious diseases associated with skin changes, such as chicken pox, measles, impetigo, pityriasis rosea, and others. Identify chronic skin problems, such as acne vulgaris or rosacea, psoriasis, and eczema. Determine the history of any previous skin treatments, biopsies, or procedures, as well as general surgical history. Because disorders in other systems frequently affect the skin, ask about the history of cardiovascular, respiratory, hepatic, immunologic, and endocrine dis- orders. Identify any recent exposures to others who have been ill and/or who have had obvi- ous skin problems that might have been contracted. Many medications affect the skin, and a list of all prescribed and over-the-counter agents should be obtained, including herbal and nutritional supplements. Table 2-1 includes a nonexhaustive list of medications with potential adverse skin effects. Finally, ask the patient how he or she generally tolerates expo- sure to the elements, such as heat, cold, and sun, to determine whether environmental exposure is responsible for or may contribute to the patient’s complaint. Family History The family history should include the occurrence of such skin diseases as eczema, psoria- sis, and skin cancer, as well as other disorders commonly associated with skin problems, such as cardiovascular, respiratory, hepatic, immunologic, and endocrine disorders. Habits Investigate habits related to skin, hair, and nail care. Identify any chemicals used in groom- ing, as well as potential exposures encountered through work and recreational activities. Identify occupational, daily living, and recreational activities that could be responsible for lesions resulting from friction, infestations, environmental extremes (heat/cold/sun), and other variables. Dietary history is helpful for identifying the potential sources of atopic reactions. PHYSICAL EXAMINATION Order of the Exam During the general examination of the skin, compare side to side for symmetry of color, texture, temperature, and so on. There are many situations in which additional equipment, such as a magniﬁer, Copyright © 2006 F.
This pattern of response by helper T cells is termed a TH1 response buy 5gm bactroban overnight delivery acne 30s female, because it is associated with the differentiation of naive T helper (TH0) lymphocytes into mature TH1 lymphocytes buy bactroban 5gm line acne 1800s. Similarly, the T helper cells of persons without atopy respond to presentation of potentially allergenic peptides by producing IFN-γ and directing the production of allergen-specific IgG1 and IgG4 anti- bodies. This type of T helper cell response is termed a TH2 response. IL-4 and IL-13 share a num- ber of functions, which are mediated through the IL-4Rα/IL-13Rα heterodimer. However, only IL-4 is able to induce the differentiation of TH0 cells to TH2 cells and to antagonize the differentiation of TH0 cells to TH1 cells, resulting in IgE-mediated allergic inflammation. In contrast, both IL-12 and IFN-γ induce the differentiation to TH1 cells; TH2 cell differentia- tion is inhibited by IFN-γ. Differentiation to TH1 cells results in cell-mediated immunity and inflammation. Therefore, the differentiation of TH0 cells to either TH1 cells or TH2 cells appears to be the crucial event that determines which type of immune response will fol- low. A 28-year-old graduate student with a history of chronic allergic rhinitis and asthma presents to your clinic. His symptoms, which are continuous, have been somewhat refractory to the therapies you have tried thus far. He recently ran across a proposed new drug therapy for asthma while reading a scientific journal. The name of this drug is omalizumab, and he asks you to explain how it works. Which of the following responses is the most accurate answer to this patient’s question? Omalizumab is a monoclonal antibody that is directed against the tumor necrosis factor (TNF) receptor; it inhibits the action of TNF B. Omalizumab is a monoclonal antibody directed against the Fcε portion of IgE; it inhibits activation of mast cells C. Omalizumab is a monoclonal antibody directed against the IL-5 recep- tor; it inhibits eosinophil development D. Omalizumab is a cyclic polypeptide immunosuppressant that suppress- es inflammation Key Concept/Objective: To understand the mechanism of action of omalizumab, a promising new therapeutic agent directed against allergic response Clearly, treatment that interferes with IgE activation of mast cells and basophils may be beneficial. Omalizumab, a recombinant, humanized monoclonal antibody directed against the Fcε portion of IgE, has recently been developed. Important features of this anti- IgE molecule are (1) it does not bind IgE already attached to FcεRI and, therefore, does not cause anaphylaxis; (2) it does not activate complement; and (3) it has a much longer half- life than IgE. In phase III trials, omalizumab was administered by subcutaneous injections given every 2 or 4 weeks to patients with allergic rhinitis or with allergic asthma of vary- ing severity. All studies showed dramatic reductions in free IgE levels that were dependent on omalizumab dose as well as baseline IgE levels. The posttreatment level of free IgE directly correlated with reduced symptom scores, reduced use of rescue medication, and improved quality of life. For asthma, significant reductions in asthma exacerbations, in hospitalizations for asthma, and in the dose of inhaled or oral steroids were also found. As levels of serum IgE decreased, so did surface expression of FcåRI on basophils. An 18-year-old woman is brought to the emergency department after a bee sting. Her heart rate is 110 beats/min; her blood pressure is 80/40 mm Hg; and her respiratory rate is 28 breaths/min. As you prepare to initiate supportive therapy and empir- ical treatment for anaphylaxis, the nurse, who has drawn blood, asks what tests you would like to order. Which of the following serum markers, if elevated, most consistently suggests anaphylaxis as the cause of hypotension? Tryptase 10 BOARD REVIEW Key Concept/Objective: To know a serum marker that identifies anaphylaxis as a cause of hypotension Peak plasma levels of histamine occur 5 minutes after insect-sting-induced anaphylaxis begins and decline to baseline within 20 minutes.
