Sensation 104 Nerve Pathways From the receptor, information is transmitted to the afferent fibers of the pseudounipolar spinal ganglion cells, whose efferent fibers reach the spinal cord by way of the dorsal root. A synapse onto a second neuron in the sensory pathway is made either immediately, in the posterior horn of the spinal cord (protopathic system), or more rostrally, in the brain stem (epicritic/lemniscal system). The highest level of the somatosensory pathway is the contralateral primary somatosensory cortex. The somatotopic organization of the somatosensory pathway is preserved at all levels. Next, sensation to pressure and vibration stimuli are tested, as is acrognosis (posture sense), to evaluate proprioception. Sensory disturbances commonly cause disturbances of posture (tests: Romberg test, standing on one leg) or gait (p. Apparent abnormalities should be interpreted in conjunction with findings of other types, such as abnormal reflexes or paresis. Sensory dysfunction may involve not only a diminution or absence of sensation (hypesthesia, anesthesia), but also sensations of abnormal type (paresthesia, such as prickling or formication) or spontaneous pain (dysesthesia, often of burning type). Patients often use the colloquial term "numbness" to mean hypesthesia, anesthesia, or paresthesia; the physician should ask specific questions to determine what is meant. Localization of Sensory Disturbances Sensation Clinical Features Localized sensory disturbance (not in a dermatomal or peripheral nerve distribution)2 Often pain and paresthesia at first, then sensory deficit, in a distribution depending on the site of the lesion Distal symmetrical sensory disturbances Bilateral symmetrical or asymmetrical thigh pain Multiple sensory and motor deficits in a single limb Unilateral or bilateral, monoradicular or polyradicular deficits Spinal ataxia, incomplete or complete cord transection syndrome (p. Sensation Pain Pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage (International Association for the Study of Pain). Pain evokes a behavioral response involving nocifensor activity as well as motor and autonomic reflexes. Nociceptors for mechanical, thermal, and chemical stimuli are found in all body organs except the brain and spinal cord. By releasing neuropeptides, the nociceptors can produce a neurogenic sterile inflammatory response that enhances nociception (peripheral sensitization). Nociceptive impulses travel in peripheral nerves to the posterior horn of the spinal cord. Here, the incoming information is processed by both pain-specific and nonspecific (wide dynamic range) neurons. Central sensitization processes arising at this level may lower the nociceptor threshold and promote the development of chronic pain (such as phantom limb pain after amputation). Ascending impulses reach the brain through the spinothalamic and spinoreticular tracts as well as other pathways to a number of different brain regions involved in nociception. The reticular formation regulates arousal reactions, autonomic reflexes, and emotional responses to pain. The somatosensory cortex is mainly responsible for pain differentiation and localization. Neurotransmitters and neuropeptides are involved in nociception on different levels. Various neurotransmitters and neuropeptide systems play a role in the mechanism of action Types of Pain (See Table 9, p. Somatic pain is the variety of nociceptive pain mediated by somatosensory afferent fibers; it is usually easily localizable and of sharp, aching, or throbbing quality. It is mediated peripherally by C fibers and centrally by spinal cord pathways terminating mainly in the limbic system. This may explain the unpleasant and emotionally distressing nature of visceral pain. Visceral pain may be felt in its site of origin or may be referred to another site. It is always referred to the sensory distribution of the affected neural structure. The pain is persistent and diffuse, and of burning, stabbing, or throbbing quality, often in association with allodynia (pain evoked by a normally nonpainful stimulus) and hyperpathia (abnormally intense pain evoked by a normally painful stimulus). It may be accompanied by motor disturbances (paresis, disuse of limb), autonomic disturbances (sweat secretion or circulatory disturbances), trophic changes (edema, muscle atrophy, joint swelling, bone destruction), and reactive mental changes (depression, anxiety).

Carbohydrate malabsorption (lactose, fructose, sorbitol): Dietary modification, lactase supplements. Often presents with diarrhea and failure to thrive, although it may be asymptomatic. Its prevalence is estimated at 1 in 300 to 1 in 500 and is highest among those of western European descent. It also has a strong hereditary component (10% prevalence among first-degree relatives). The disease course may be complicated by intestinal lymphomas and adenocarcinomas. Presents with chronic diarrhea, steatorrhea, bloating, abdominal pain, flatulence, and weight loss. Fatigue, anemia, bleeding diathesis, osteopenia, and stunted growth are also seen. Dermatitis herpetiformis (pruritic papulovesicles over the extensor surfaces) is a common feature, as are cheilosis and glossitis. Labs: Reveal anemia (iron deficiency from iron malabsorption, folate), hypocalcemia, hypokalemia, and hypomagnesemia. Definitive diagnosis is made with the triad of a serology, histology, and clinical/serologic response to the withdrawal of gluten from the diet. Diet: Removal of gluten is essential but may be difficult given the ubiquity of wheat flour. Steroids: Consider in the small percentage of patients who are refractory to a gluten-free diet. Consider steroid therapy or rule out malignancy in those failing to respond to dietary changes. Compliance in pregnant women is important because of the risk of miscarriage and congenital malformation. Forty percent of patients have impaired ability to work, avoid social functions, cancel appointments, or stop travel because of the severity of their symptoms. Onset is typically in the late teens to 20s and/or after infectious gastroenteritis. In the developed world, women are more commonly affected than men, but in India the opposite is the case. Exam is often normal, or patients present with mild to moderate abdominal tenderness. Severe upper abdominal pain/dyspepsia: Consider endoscopy (flexible sigmoidoscopy for those < 40 years of age; colonoscopy for those > 40 years). Constipation is defined as < 3 bowel movements per week or excessive difficulty and straining at defecation. Prevalence is high in the Western world and is highest among children and the elderly. Systemic: Diabetes, hypothyroidism, hypokalemia, hypercalcemia, autonomic dysfunction. Medications: Narcotics, diuretics, calcium channel blockers, anticholinergics, psychotropic drugs, clonidine. Exam is often normal but may present with abdominal distention, tenderness, and/or mass; external hemorrhoids, anal fissures, and fecal impaction; or rectal prolapse with straining. Age 50 or < 50 years with a failed fiber/fluid trial or fecal occult blood or anemia: Barium enema; flexible sigmoidoscopy or colonoscopy. Refractory constipation: Pelvic floor dysfunction: Anorectal manometry and balloon expulsion studies and defecography. Slow-transit constipation: Radiopaque marker studies and scintigraphy with serial examination of marker transit using radiographs. In asymptomatic patients, the disorder is associated with excessive flatulence and pellet-like stools. Barium enema: Accurate for diverticulosis, but insufficient to rule out colorectal cancer.
On exam asthma gluten order discount fluticasone online, the pupil is midsized and does not react to light asthma treatment pediatrics order fluticasone on line amex, and the cornea is "steamy" (see Figure 2 asthma yoga generic fluticasone 500 mcg with mastercard. Branching (dendritic) ulcers on fluorescein stain test are diagnostic (see Figure 2 asthma definition rhetoric buy generic fluticasone 250mcg. Additional etiologies of red eye include the following: Foreign body: Characterized by a sharp superficial pain. Gonorrheal conjunctivitis: Presents with abrupt onset of redness and purulent discharge in sexually active adults. Chlamydial conjunctivitis: Associated with chronic red eye in sexually active adults. Conjunctival injection and discharge Unilateral or bilateral redness; watery discharge. Pupillary constriction (topical pilocarpine), pressure reduction (topical -blockers, acetazolamide). Presents with irritation, burning, and itching along with findings of red lids and scale in the lashes. Treatment by an ophthalmologist consists of incision and curettage or corticosteroid injection. Bacterial keratitis is an important complication of corneal abrasions in contact lens wearers. Contact lens wearers Loss of Vision with corneal abrasions should receive prophylactic topical antibiotics and close follow-up. Etiologies of acute loss of vision include the following: Retinal artery occlusion: Commonly due to an embolus; associated with giant cell arteritis. Characterized by sudden, painless, unilateral blindness and by a "cherry-red spot" in the macula (see Figure 2. Vitreous hemorrhage: Due to vitreous detachment, proliferative diabetic retinopathy, or retinal tears (see Figure 2. Presents with unilateral blurred vision that progressively worsens (floaters or lights in peripheral vision). Amaurosis fugax ("fleeting blindness"): Due to retinal emboli from ipsilateral carotid disease. Central retinal vein occlusion with extensive superficial retinal hemorrhage obscuring macular and optic nerve detail. High-grade carotid stenoses may benefit from carotid endarterectomy; lower-grade stenoses benefit from antiplatelet drugs. Open-angle glaucoma: Loss of peripheral vision ("tunnel vision") over a period of years. Treatment includes a combination of topical -blockers, 2-agonists, and prostaglandin analogs. Nonproliferative diabetic retinopathy: the most common cause of legal blindness in adult-onset diabetes. Characterized by dilation of veins, microaneurysms, hard exudates, and retinal hemorrhages (see Figure 2. Proliferative diabetic retinopathy: Presents with neovascularization; vitreous hemorrhage is a common complication (see Figure 2. Note the macular drusen and retinal pigment epithelial atrophy (scalloped pigment loss) that are typical of agerelated macular degeneration. These vessels do not move when the overlying conjunctiva is moved with a cotton-tipped applicator. Hypofunctioning of the lacrimal glands the aqueous component of tears and thus leads to dry eyes. Bacterial sinusitis results from impaired mucociliary clearance and obstruction of the osteomeatal complex. Causative organisms of acute sinusitis include Streptococcus pneumoniae, other streptococci, Haemophilus influenzae, and, less commonly, S. Presents as sinusitis with more extreme facial pain accompanied by necrotic eschar of the nasal mucosa and cranial neuropathies in the late stages.

Advanced maternal age and high parity pregnancies are prevalent in sub-Saharan African countries where parity rates are high and childbearing often continues until menopause extrinsic asthma unspecified definition cheap fluticasone 250 mcg without a prescription. It is important to also consider that a high parity pregnant mother may also be of advanced maternal age asthma treatment for dogs generic fluticasone 250mcg fast delivery, and hence her risks are compounded-and may be made graver still if her pregnancies are spaced too closely asthma treatment journal purchase generic fluticasone line. A review of the literature shows that while advanced maternal age- and high parity-specific research exists asthma treatment cannabis purchase on line fluticasone, much is from high-income settings in the West. Only a few studies from sub-Saharan Africa exist,10,11 and most of this work focuses on establishing risks with little to no research on knowledge, attitudes, and behaviors relating to such pregnancy. Family planning programs typically place less attention on addressing pregnancies among women of advanced maternal age or high parity. Niger, with a largely Muslim population, generally has more conservative social and religious norms and a larger rural population than Togo, and women in Niger desire more children than they have. First, for more than a decade, Niger has had the highest total fertility rate in the world, currently at 7. The mean ideal number of children for women in Niger has increased over the years, from 8. These same reports show the ideal number of children is higher among men than women in each country: currently married men in Niger desire 12. This, too, has been increasing in Niger and decreasing in Togo over the past 25 years. High fertility rates and high parity status are also coupled with early childbearing in both countries, which carries with it its own significant maternal and infant morbidity and mortality risks. Contraceptive use is relatively low in both Niger (14% of married women)13 and Togo (20% of married women). The Government of Niger has committed to increase the contraceptive prevalence rate to 50% in 2020, from 10. The Niger government plans to achieve this by increasing contraceptive availability. The selection of study sites was based on several factors including fertility rate, prevalence of advanced maternal age pregnancies, cultural diversity, and level of contraceptive use as well as accessibility from the capital. Selecting sites closer to capital cities is one limitation of the study, as knowledge, attitudes, and behaviors prevalent among populations living near a capital city may not be representative of those of more remote communities. Further, participants in each site were presumed to live in each location, rather than having traveled to research sites to participate in the study. As such, findings should be interpreted as specific to populations living in each site and cannot be assumed to be representative of prevailing knowledge, attitudes, and behaviors throughout each country. In Niger, we conducted the study in Niamey (urban), Koygoro (rural), and Mokko (rural) in the Dosso region, which is approximately 130 km from the capital city of Niamey. High parity pregnancies can lead to complications including anemia in the mother, postpartum hemorrhage, and fetal malpresentation. This region was chosen because of its mix of religions (Muslim, Christian, and indigenous religions). In each study site: Focus group discussions were conducted with women of advanced maternal age and/or high parity and with male partners of women in these risk categories to gather data about collective perceptions and attitudes that influence choices about reproduction, particularly advanced maternal age and/or high parity pregnancies. Case studies were collected from individual women of advanced maternal age and/or high parity who had difficult pregnancies or deliveries. These histories highlighted knowledge and attitudes of these women about risks with such pregnancies and how these impacted their pregnancies and deliveries. In-depth interviews were conducted with: Advanced maternal age and high parity couples to understand how marriage, gender dynamics, and individual, cultural, economic, and other factors impacted fertility desires and reproductive health decision making regarding advanced maternal age and high parity pregnancies. We conducted focus group discussions and in-depth interviews in Zharma and Hausa languages in Niger and in Mina and Kabiye languages in Togo; all were recorded and transcribed in the field into French.
