The normal esophagus is a hollow, highly distensible muscular tube that extends from the epiglottis in the pharynx, at about the level of the C6 vertebra, to the gastroesophageal junction at the level of the T11 or T12 vertebra. Measuring between 10 and 11 cm in the newborn, it grows to a length of about 25 cm in the adult. For the endoscopist, the esophagus is recorded as the anatomic distance between 15 and 40 cm from the incisor teeth, with the gastroesophageal junction located at the 40-cm point. Although the pressure in the esophageal lumen is negative compared with the atmosphere, manometric recordings of intraluminal pressures have identified two higher-pressure areas that remain relatively contracted in the resting phase. Both "sphincters" are physiologic, in that there are no anatomic landmarks that delineate these higher-pressure regions from the intervening esophageal musculature. It has three components: a nonkeratinizing stratified squamous epithelial layer, lamina propria, and muscularis mucosa. The basal cells, constituting 10% to 15 % of the mucosal thickness, are reserve cells with great proliferative potential. A small number of specialized cell types, such as melanocytes, endocrine cells, dendritic cells, and lymphocytes, are present in the deeper portion of the epithelial layer. The lamina propria is the nonepithelial portion of the mucosa, above the muscularis mucosae. It consists of areolar connective tissue and contains vascular structures and scattered leukocytes. Finger-like extensions of the lamina propria, called papillae, extend into the epithelial layer. The muscularis mucosae is a delicate layer of longitudinally oriented smooth-muscle bundles. The submucosa consists of loose connective tissue containing blood vessels, a rich network of lymphatics, a sprinkling of leukocytes with occasional lymphoid follicles, nerve fibers (including the ganglia of the Meissner plexus), and submucosal glands. Submucosal glands connected to the lumen by squamous epithelium-lined ducts are scattered along the entire esophagus but are more concentrated in the upper and lower portions. As is true throughout the alimentary tract, the muscularis propria consists of an inner circular and an outer longitudinal coat of smooth muscle with an intervening, well-developed myenteric plexus (Auerbach plexus). The muscularis propria of the proximal 6 to 8 cm of the esophagus also contains striated muscle fibers from the cricopharyngeus muscle. Besides creating a unique histologic interplay of smooth muscle and skeletal muscle fibers, this feature explains why skeletal muscle disorders can cause upper esophageal dysfunction. In sharp contrast to the rest of the gastrointestinal tract, the esophagus is mostly devoid of a serosal coat. Only small segments of the intra-abdominal esophagus are covered by serosa; the thoracic esophagus is surrounded by fascia that condenses around the esophagus to form a sheathlike structure. In the upper mediastinum, the esophagus is supported by this fascial tissue, which forms a similar sheath around adjacent structures, the great vessels and the tracheobronchial tree. This intimate anatomic proximity to important thoracic viscera is of significance in permitting the ready and widespread dissemination of infections and tumors of the esophagus into the posterior mediastinum. The rich network of mucosal and submucosal lymphatics that runs longitudinally along the esophagus further facilitates spread. The main functions of the esophagus are to conduct food and fluids from the pharynx to the stomach, to prevent passive diffusion of substances from the food into the blood, and to prevent reflux of gastric contents into the esophagus. The mechanisms governing this motor function are complex, involving both extrinsic and intrinsic innervation, humoral regulation, and properties of the muscle wall itself. Maintenance of sphincter tone is necessary to prevent reflux of gastric contents, which are under positive pressure relative to the esophagus. Pathology Lesions of the esophagus run the gamut from highly lethal cancers to the merely annoying "heartburn" that has affected many a partaker of a large, spicy meal. Esophageal varices, the result of cirrhosis and portal hypertension, are of major importance, since their rupture is frequently followed by massive hematemesis (vomiting of blood) and even death by exsanguination. Distressing to the physician is that all disorders of the esophagus tend to produce similar symptoms, namely heartburn, dysphagia, pain, and/or hematemesis. Heartburn (retrosternal burning pain) usually reflects regurgitation of gastric contents into the lower esophagus. Dysphagia (difficulty in swallowing) is encountered both with deranged esophageal motor function and with diseases that narrow or obstruct the lumen. Pain and hematemesis are sometimes evoked by esophageal disease, particularly by those lesions associated with inflammation or ulceration of the esophageal mucosa. The clinical diagnosis of esophageal disorders often requires specialized procedures such as esophagoscopy, radiographic barium studies, and manometry. The most common is ectopic gastric mucosa in the upper third of the esophagus ("inlet patch"), occurring in up to 2% of individuals. The acid secretions of the ectopic gastric mucosa or pancreatic enzymatic secretions can produce localized inflammation and discomfort. These are usually duplication cysts, containing double smooth muscle layers and derived from the lower esophagus in 60% of cases. Rarely, bronchial or parenchymal pulmonary tissue may arise from the upper gut and is denoted bronchogenic cyst or pulmonary sequestration, respectively. Lastly, impaired formation of the diaphragm may permit herniation of abdominal viscera into the thorax. When severe, this lesion is incompatible with life, since the lungs are severely hypoplastic at the time of birth. This condition is to be distinguished from hiatal hernias, to be discussed presently. Because they cause immediate regurgitation when feeding is attempted, they are usually discovered soon after birth. Absence (agenesis) of the esophagus is extremely rare; much more common are atresia and fistula formation (. In atresia, a segment of the esophagus is represented by only a thin, noncanalized cord, with a proximal blind pouch connected to the pharynx and a lower pouch leading to the stomach. It rarely occurs alone, but is usually associated with a fistula connecting the lower or upper pouch with a bronchus or the trachea. Associated anomalies include congenital heart disease, neurologic disease, genitourinary disease, and other gastrointestinal malformations. Atresia sometimes is associated with [3] the presence of a single umbilical artery. Aspiration and paroxysmal suffocation from food are obvious hazards; pneumonia and severe fluid and electrolyte imbalances may also occur. Well-developed webs rarely protrude more than 5 mm into the lumen, with a thickness of 2 to 4 mm. When an upper esophageal web is accompanied by an iron-deficiency anemia, glossitis, and cheilosis, the condition is referred to as the Paterson-Brown-Kelly or Plummer-Vinson syndrome, with an attendant risk for postcricoid esophageal carcinoma. Esophageal rings are concentric plates of tissue protruding into the lumen of the distal esophagus.

Hirschsprung also has a strong association with hearing disease usually is sporadic with a risk of about impairment. Trisomies are most typ born and pediatricians must know how to ically sporadic events and recurrence varies diagnose and provide additional care. Asymptomatic congenital cytomegalovirus infection is a leading cause of sensorineural hearing loss, which can occur in approximately 7% of infants. Hearing loss is often progressive and may not be detected until the patient is older. Hyperbilirubinemia at levels requiring exchange transfusion is also associated with sensorineural hearing loss. Aminoglycosides put an infant at increased risk for hearing loss particularly when used in combination with other ototoxic drugs or when levels are not appropriately Figure 3-4 (Courtesy of Emily A.

Unlike the neurofibrillary tangles of Alzheimer disease when administering medications 001mg is equal to buy generic biltricide line, Pick bodies do not survive the death of their host neuron and do not remain as markers of the disease medicine nausea buy biltricide 600 mg line. The onset of the disease is usually between the fifth and seventh decades medicine in french order biltricide 600 mg otc, and males are affected approximately twice as frequently as are females medicine in motion order biltricide 600mg without prescription. There is widespread neuronal loss in the globus pallidus, subthalamic nucleus, substantia nigra, colliculi, periaqueductal gray matter, and dentate nucleus of the cerebellum. Globose neurofibrillary tangles are found in these affected regions, in neurons as well as in glia. Ultrastructural analysis reveals 15-nm straight filaments that are composed of 4 repeat tau. Analysis of the tau gene has shown that there is an extended haplotype (a series of polymorphic markers spread out along the gene that are in complete linkage disequilibrium; that is, recombination events do not appear to occur between the sites). On macroscopic examination, there is cortical atrophy, mainly of the motor, premotor, and anterior parietal lobes. The regions of cortex show severe loss of neurons, gliosis, and "ballooned" neurons (neuronal achromasia) that can be highlighted with immunocytochemical methods for phosphorylated neurofilaments. Tau immunoreactivity has been found in [164] [165] astrocytes ("tufted astrocytes"), oligodendrocytes ("coiled bodies"), basal ganglionic neurons, and, variably, cortical neurons. The substantia nigra and locus ceruleus show loss of pigmented neurons, neuronal achromasia, and tangles. The disease is characterized by extrapyramidal rigidity, asymmetric motor disturbances (jerking movements of limbs: "alien hand"), and sensory cortical dysfunction (apraxias, disorders [168] [169] [170] of language); cognitive decline occurs, and may be prominent in some cases. Frontotemporal Dementias Without Tau Pathology Some cases with clinical and pathologic findings involving these brain regions do not show evidence of Tau deposition. Some cases with this pattern are found in association with motor neuron disease (see below); in this setting, Tau-negative, ubiquitin-positive inclusions can be found in superficial cortical layers in temporal and frontal lobe and in the dentate gyrus. Other cases show no specific inclusions [172] but rather have cortical atrophy and some thalamic gliosis. With time and increased biochemical and molecular investigations, these unusual entities are likely to be reclassified. Vascular Dementia [173] It is now clear from autopsy studies of individuals who were carefully studied during life that various types of vascular injury to the brain can result in dementia. Some individuals with a rapidly progressive cognitive decline have vasculitis (discussed above) and will often show improvement with treatment. Among the irreversible disorders, several specific entities have been identified, which can be separated in part by their clinical course (typically a stepwise progression rather than a gradual decline) and imaging features. Additionally, dementia has been associated with so-called strategic infarcts, which are usually embolic and involve brain regions such as the hippocampus, dorsomedial thalamus, or frontal cortex including cingulate gyrus. It has been found that patients with vascular changes above a certain threshold have a [174] lower burden of plaques and tangles for their level of cognitive impairment than do those without vascular-based cerebral pathology. In general, they can be categorized as manifesting either a reduction of voluntary movement or an abundance of involuntary movement. The basal ganglia and especially the nigrostriatal pathway play an important role in the system of positive and negative regulatory synaptic pathways that serve to modulate feedback from the thalamus to the motor cortex. The most important disorders in this group are those associated with parkinsonism and Huntington chorea. Parkinsonism Parkinsonism is a clinical syndrome characterized by diminished facial expression, stooped posture, slowness of voluntary movement, festinating gait (progressively shortened, accelerated steps), rigidity, and a "pill-rolling" tremor. This type of motor disturbance is seen in a number of conditions that have in common damage to the nigrostriatal dopaminergic system. Parkinsonism may also be induced by drugs that affect this system, particularly dopamine antagonists and toxins. Parkinson Disease this diagnosis is made in patients with progressive parkinsonism in the absence of a toxic or other known underlying etiology. Although these make up a limited number of cases, they have contributed to our understanding of the pathogenesis of the disease. On pathologic examination, the typical macroscopic findings are pallor of the substantia nigra (. On microscopic examination, there is loss of the pigmented, catecholaminergic neurons in these regions associated with gliosis. Deep tendon reflexes are depressed or absent, but an extensor plantar reflex is typically present. Joint position and vibratory sense are impaired, and there is sometimes loss of pain and temperature sensation and light touch. There is a high incidence of cardiac disease with arrhythmias and congestive heart failure. Most patients become wheelchair-bound within about 5 years of onset; the cause of death is intercurrent pulmonary infections and cardiac disease. Affected individuals inherit abnormal forms of the frataxin gene from both parents and have extremely low levels of the protein. In some cases of Friedreich ataxia, one of the mutant alleles harbors a missense or nonsense mutation. Frataxin undergoes processing and ends up in the inner mitochondrial membrane, where it has been suggested to play [219] [220] a role in regulation of iron levels. Because of the need for this metal in many of the complexes of the oxidative phosphorylation chain, mutations in frataxin have been suggested to result in generalized mitochondrial dysfunction. Thus, Friedreich ataxia shares biologic features with other spinocerebellar ataxias (anatomic distribution of pathology, trinucleotide repeat expansion) and the mitochondrial encephalopathies. The spinal cord shows loss of axons and gliosis in the posterior columns, the distal portions of corticospinal tracts, and the spinocerebellar tracts. Large dorsal root ganglion neurons are also decreased in number; their large myelinated axons, traveling first in the dorsal roots and then in dorsal columns, therefore undergo secondary degeneration. Multifocal destruction of myocardial fibers with inflammation and fibrosis is detectable in about half the patients who come to autopsy examination. Ataxia-Telangiectasia Ataxia-telangiectasia (Chapter 7) is an autosomal-recessive disorder characterized by an ataxic-dyskinetic syndrome beginning in early childhood, caused by neuronal degeneration predominantly in the cerebellum, the subsequent development of telangiectasias in the conjunctiva and skin, and immunodeficiency. The carrier frequency of ataxia-telangiectasia has been estimated at 1%; in these individuals, the mutated ataxia-telangiectasia allele may underlie an increased risk of cancer, specifically breast cancer. The abnormalities are predominantly in the cerebellum, with loss of Purkinje and granule cells; there is also degeneration of the dorsal columns, spinocerebellar tracts, and anterior horn cells and a peripheral neuropathy. Patients first come to medical attention because of recurrent sinopulmonary infections and unsteadiness in walking. Later on, speech is noted to become dysarthric, and eye movement abnormalities develop. Many affected individuals develop lymphoid malignant disease (T-cell leukemia, T cell lymphoma); gliomas and carcinomas have been reported in some. Denervation of muscles from loss of lower motor neurons and their axons results in muscular atrophy, weakness, and fasciculations; the corresponding histologic changes in nerve and muscle are discussed in Chapter 27. The clinical manifestations include paresis, hyperreflexia, spasticity, and extensor plantar responses (Babinski sign). Sensory systems and cognitive functions are unaffected, but types with dementia do occur. The disease affects men slightly more frequently than women and becomes clinically manifest in the [224] fifth decade or later. Five per cent to 10% of cases are familial, mostly with autosomal-dominant inheritance. A wide variety of missense mutations have been identified that appear to generate an adverse gain-of-function phenotype. Among the [226] [227] mutations, the A4V mutation is the most common (approaching 50% of cases), is associated with a rapid course, and rarely has upper motor neuron signs. On macroscopic examination, the anterior roots of the spinal cord are thin; the precentral gyrus may be atrophic in especially severe cases. Microscopic examination demonstrates a reduction in the number of anterior horn neurons throughout the length of the spinal cord with associated reactive gliosis and loss of anterior root myelinated fibers. Similar findings are found with involvement of the hypoglossal, ambiguus, and motor trigeminal cranial nerve nuclei. Skeletal muscles innervated by the degenerated lower motor neurons show neurogenic atrophy.
