How Does MS Affect the Nervous System

In contrast to many diseases that affect a single part of the human body, MS affects two different body systems the immune system and the nervous system. The immune system is not a distinct organ like the brain or liver. Instead, it is composed of many different types of molecules and cells known as white blood cells that travel through the bloodstream. The immune cells use chemical messages to protect the body from attack by bacteria, viruses, and cancers. MS is believed to be an autoimmune...

Normal Urothelial Histology and Cytology

The majority of the collecting system is lined by urothelium transitional epithelium . Variable areas of the bladder and urethra may be lined by glandular epithelium simple columnar , especially in the trigone and the dome of the bladder the vestigial urachus pa-raurethral glands, which provide lubrication for the urethra, might also be a source of glandular epithelium from that area. Cystitis cystica or glandularis, arising in Brunn's nests in the bladder mucosa, may shed groups of atypical...

Atypical Urothelial Cells Indeterminate for Neoplasia

Unfortuntely, as in every other body site, cytologic samples from the urinary tract are not always readily placed into distinct categories. An atypical interpretation is appropriate when morphologic changes exceed those described as benign cellular changes, but lack clear signs of neoplasia Figs. 2.7, 2.15, 2.33 . This is generally encountered when dealing with a sample from a patient with a low grade lesion, especially those called low malignant potential LMP , or in the presence of severe...

Treatment of Combined Colonic Inertia and Obstructed Defecation

Transit studies and anorectal physiology tests can subdivide severely constipated patients into three groups colonic inertia causing slow transit, obstructed defecation, and a combination of both. Patients with obstructed defecation may have mechanical outlet obstruction related to the presence of anatomic abnormalities such as a rectocele, or functional outlet obstruction. The principles of treating slow-transit constipation or obstructed defecation alone are generally agreed upon. The optimal...

Extrapyramidal Motor Pathways

The extrapyramidal pathways are those motor pathways that do not pass through the pyramids of the medulla oblongata. They consist of central pathways that modulate CNS motor areas in cerebral cortex, cerebellum, the brain stem, and spinal cord. The primary function of the extrapyramidal system is the 'fine-tuning' of voluntary movement to render it amenable to higher levels of conscious control. The absence of such fine-tuning becomes obvious in conditions such as parkinsonism see p. 370 , when...

Bioinformatics And Vaccine Discovery

Immunoinformatics is a newly emergent subdiscipline within the informatic sciences that deals specifically with the unique problems of the immune system. Like bioinformatics, immunoinformatics complements, but never replaces, laboratory experimentation. It allows researchers to address, in a systematic manner, the most important questions in the still highly empirical world of immunology and vaccine discovery. The first vaccine was discovered by Edward Jenner in 1796, when he used cowpox, a...

Ligature Strangulation

In ligature strangulation, the pressure on the neck is applied by a constricting band that is tightened by a force other than the body weight. Virtually all cases of ligature strangulation are homicides. In the authors' experience, ligature strangulation is the most common method of homicidal asphyxia, though the incidence of manual strangulation follows fairly closely. In a study of 133 homicides caused by asphyxia, ligature strangulation accounted for 48 of the deaths manual strangulation for...

Elevated Eosinophil and Basophil Counts

In accordance with their physiological role, an increase in eosinophils gt 400 1, i.e. for a leukocyte count of 6000, more than 8 in the differential blood analysis is usually due to parasitic attack p. 5 . In the Western hemisphere, parasitic infestations are investigated on the basis of stool samples and serology. Strongyloides stercoralis in particular causes strong, sometimes extreme, elevation of eosinophils may be up to 50 . However, eosinophilia of variable degree is also seen in ameba...

Transverse Section of Medulla Oblongata

The spinal cord becomes the medulla oblongata, which also contains white and gray matter, but the arrangement changes, due to the embryonic expansion of the central canal to form the hindbrain vesicle, which will become the fourth ventricle. Development of the ventricle pushes dorsally situated structures more dorsolaterally. The transition is clearly seen in transverse section. The spinal cord becomes the medulla, which initially resembles the upper cervical segments. The substantia gelatinosa...

Hughes Tarsoconjunctival Flap Procedure

The Hughes procedure is a two-staged operation for reconstruction of total or near total lower eyelid defects. As with the free tarsoconjunctival graft, a block of tarsus and conjunctiva is marked out on the ipsilateral upper lid. However, the upper border is left attached superiorly and a conjunctival flap is dissected off of the underlying Muller's muscle to the superior fornix Fig. 10 . The tarsal flap is advanced down into the lower lid defect and sutured to residual tarsus or canthal...

Deviated Nasal Septum

A congenital or traumatic dislocation of the septal cartilage into one nasal fossa causes unilateral nasal obstruction. If the obstruction is marked, or complicated by recurrent sinusitis, a septal correction is effective surgery. The time-honored operation for this is a submucous resection SMR , but a septoplasty in which cartilage is preserved and repositioned rather than removed is now used. The SMR operation involves removal of much of the septal cartilage and loss of nasal support with...

Indicated Supporting Diagnostic Data

Examination of the skin remains a discipline that relies heavily on the basic clinical skills of vision and touch. If this information is combined with the practitioner's knowledge of the disease process, the correct diagnosis can be determined with a minimum of expensive laboratory testing. The dermatologist usually orders labwork to confirm a diagnosis or to stage the disease process rather than using it to seek a diagnosis. After all, the disease process is evolving before your eyes. In...

How failing kidney function affects diabetes management

To achieve good blood sugar control in the presence of failing kidney function is a difficult task for patient and doctor. There are various reasons for this. In some people with diabetes the insulin sensitivity changes, for reasons that are often unclear the tissues no longer respond as well to insulin. This can lead to a worsening of the diabetes. Insulin - whether made by the body or injected as a drug - is partly broken down in the kidneys. When the kidneys are not functioning properly,...

Sequential Parallel and Integrated Treatment Models

There are three major models in which dually diagnosed patients are treated sequential, parallel, and integrated treatment. Each is discussed below. In sequential treatment, the more acute condition is treated first, followed by the less acute co-occurring disorder. The same staff may treat both disorders, or the less acute disorder may be treated after transfer to a different program or facility. For example, a manic patient with a cocaine use disorder needs mood stabilization before...

Soldering Flux And Antiflux

This substance is applied to a metal surface to remove oxides or prevent their formation. When the oxides are removed, the solder is free to wet and spread over the clean metal surface. Borax glass Na2B4O7 is frequently used with gold alloys because of its affinity for copper oxides. An often-cited soldering flux formula'-' is borax glass 55 parts , boric acid 35 parts , and silica 10 parts . These ingredients are fused together and then ground into a powder. Fluxes are...

Pinledge Preparations

A pinledge Fig. 10-34 is occasionally used as a single restoration, generally to reestablish anterior guidance, in which case only the lingual surface is prepared. More commonly, however, it is used as a retainer for a fixed partial denture Fig. 10-35 or to splint periodontally compromised teeth Fig. 10-36 . In these cases, one or more of the proximal surfaces are included in the preparation design to accommodate the required connector s . Retention and resistance are provided primarily by pins...

Angioedema and Urticaria

INTRODUCTION Angioedema and urticaria are common transient phenomena that result from mast cell degranulation with the release of mediators that promote vascular permeability, causing proteins and fluids to extravasate into the extracellular space. In urticaria fluid collects within the dermal tissue, whereas in angioedema fluid collects in the deeper subcutaneous space. The causes of mast cell degranulation are varied and include both immunologic and nonimmunologic mechanisms. Systemic...

Acute Cutaneous Lupus Erythematosus

The typical clinical manifestations of ACLE are characterized by a localized erythema known as the malar rash or butterfly rash on the central portion of the face or by a generalized, more widespread form Fabbri et al. 2003, Sontheimer and Provost 2003 . Localized ACLE may only affect the skin transiently, and the lesions may last for only several days up to a few weeks. Therefore, at the onset of disease, the patients may mistake this rash for sunburn and may seek medical advice only after the...

Bone Marrow Cell Composition and Principles of Analysis

As indicated above, and as will be shown below, almost all disorders of the hematopoietic system can be diagnosed using clinical findings, blood analysis, and humoral data. There is no mystery about bone marrow diagnostics.

Inhibitors of Cell Wall Synthesis

In most bacteria, a cell wall surrounds the cell like a rigid shell that protects against noxious outside influences and prevents rupture of the plasma membrane from a high internal osmotic pressure. The structural stability of the cell wall is due mainly to the murein peptidoglycan lattice. This consists of basic building blocks linked together to form a large macromolecule. Each basic unit contains the two linked aminosug-ars N-acetylglucosamine and N-acetyl-muramyl acid the latter bears a...

Peptide Sample Preparation by Ether Precipitation

This procedure is suitable for precipitating peptides from organic acids and is used routinely for concentrating synthetic peptides from the trifluoroacetic acid cleavage cocktail following 9-fluorenylmethyloxycarbonyl Fmoc solid-phase peptide synthesis. It can be used to desalt peptides in nonvolatile buffers but is not recommended for removing detergents like SDS. Take appropriate safety precautions when using this technique ether is highly flammable, and a refrigerated centrifuge and fume...

The Living Rape Victim

Rape presents a unique problem to physician clinicians in that they often inherit the burden of not only treatment, but proper collection of evidence. For the correct handling of rape cases, both medically and legally, there must be coordination between the physicians examining the victims and the police agency with jurisdiction. It is preferable that victims of rape be examined at one central hospital by experienced physicians trained in the handling and treatment of such patients and in the...

Eyelid Lesions and Tissues of Origin

The plethora of lesions that can occur on the eyelids is rather daunting, not to say confusing, to the average clinician. Many names are similar and while they may be meaningful to the pathologist based on details of microscopic findings, they often add little to the clinical recognition or management of these diseases. Placing such lesions into a more or less organized system based on anatomical tissues of origin may be a useful exercise. All lesions that involve the eyelids or any other...

Bullous Lesions in Lupus Erythematosus

The frequency of bullous lesions associated with LE BLE is low, and it has been reported that less than 5 of patients with SLE and skin changes had chronic vesicu-lobullous lesions Gammon and Briggaman 1993, Yell and Wojnarowska 1997 . Confusion has always existed concerning the nosology and classification of the bullous skin changes that can occur in patients with LE, and there has been no consensus in this area for a long time. In 1997, Sontheimer Sontheimer 1997 divided the various types of...

Acute Chorioamnionitis

Benirschke and Kaufmann feel that chorioamnionitis which they use as synonymous with acute chorioamnionitis is always their bold caused by infection 3 . Other forms of injury to the placenta, such as infarction, will also illicit an acute inflammatory reaction but will be localized to the area of injury. Acute chorioamnionitis is the most common diagnosis rendered on the placenta. Despite this, no universally accepted definition, grading, or staging system has been developed. Acute...

Parallel Group Designs

A parallel group design is a complete randomized design in which each patient receives one and only one treatment in a random fashion. Basically there are two types of parallel group design for comparative clinical trials, namely, group comparison or parallel-group designs and matched pairs parallel designs. The simplest group comparison parallel group design is the two-group parallel design which compares two treatments e.g., a treatment group vs. a control group . Each treatment group...

Blood Supply and Venous Drainage of Spinal Cord

The spinal cord is supplied with arterial blood by descending arteries that run the length of the spinal cord, and by radicular arteries that arise at the segmental level. The descending arteries comprise the paired posterior spinal arteries, and the unpaired anterior spinal artery. The posterior spinal arteries arise either from the posterior inferior cerebellar arteries see p. 43 , or from the vertebral arteries. They descend the cord on the dorsal posterior surface, medial to the dorsal...

Diaphragmatic Breathing Physiological Quieting

The breathing cycle is intimately connected to both sympathetic and parasympathetic action of the autonomic nervous system.19 Bowel and bladder function is also mediated by the autonomic nervous system.10 Conscious deep diaphragmatic breathing is one of the best ways to quiet the autonomic nervous system. This breathing effectively initiates a cascade of visceral relaxation responses. The aim of this exercise is to make the shift from thoracic breathing to abdominal breathing.19 Patients are...

Reactive Lymphocytosis

Lymphatic cells show wide variability and transform easily. This is usually seen as enlarged nuclei, a moderately loose, coarse chromatin structure, and a marked widening of the basophilic cytoplasmic layer. Clinical findings, which include acute fever symptoms, enlarged lymph nodes, and sometimes exanthema, help to identify a lymphatic reactive state. Unlike the case in acute leukemias, erythrocyte and thrombocyte counts are not significantly reduced. Although the granulocyte count is...

Cold Knife Conization

If the cytology report is positive, but no lesion is visible on gross or colposcopic examination, a cervical conization will be necessary in order to survey the entire squamoco-lumnar junction. A conization must also be performed if a previous punch biopsy of a grossly suspicious lesion showed that the noninvasive precancerous epithelium had not been completely excised. A biopsy of malignant tumors can never give information about the depth of invasion. If the clinical signs fail to reveal how...

Cognitive Models Of Ptsd

Information-processing theory has been widely used to understand the development and maintenance of anxiety disorders, including PTSD (Lang, 1979, 1985). This theory suggests that emotions, such as fear, are encoded in memory in the form of networks, where representations of anxiety-provoking events are stored. Fear networks are hypothesized to contain three important types of information (1) information about the feared stimuli or situation (2) information about the person's response to the...

Histopathologic Terminology

The use of descriptive terms in histopathology is a valuable method for standard communication which allows both the pathologist and the clinician to understand specific histologic characteristics of biological materials. One or more of these characteristics may be specific for certain lesions, thus allowing a more precise diagnosis. In some cases, knowledge of such characteristics can also help the clinician make a provisional diagnosis that might allow therapeutic decisions such as to biopsy...

Methamphetamine and Amphetamine

Methamphetamine is a potent CNS stimulant that is readily produced illicitly.14,18 In the brain, it acts by both increasing release of dopamine and blocking its re-absorption, causing hyperstimulation of receptor neurons. Methamphetamine is also a cardiovascular stimulant. It blocks re-uptake of norepinephrine and causes an increase in catecholamine release. The euphoric effect is similar to cocaine but may last as long as ten times that of cocaine. Methamphetamine is metabolized to...

Battered Baby Syndrome

The battered baby syndrome refers to a condition characterized by repeated intentional acts of trauma to a young child inflicted at the slightest or most trivial provocation. Deprivation of food and water is a variant of this trauma. Classically, the child presents to a physician or an emergency room with an acute injury accompanied by evidence of both old and recent bruises, fractures, and other injuries. There might be skull or extremity fractures, ruptured viscera, subdural hematomas, or...

Stab Wounds by Anatomical Location

Most fatal stab wounds are located in the left chest region. Among a number of explanations is that most people are right handed and, when facing a victim, will tend to stab the left chest. In addition, if the intention is to kill someone, one would stab in the left chest where the heart is thought to be. Most fatal stab wounds of the chest involve injury to the heart or aorta. Deaths due solely to a stab wound of the lung are less common. Fatal stab wounds of the right chest usually involve...

Evaluation of Eyelid Malpositions

A thorough eyelid examination should be included in the documentation of any eyelid malposition. Accurate diagnosis of eyelid dystopia including some determination of its etiology is essential prior to consideration of surgical or nonsurgical correction. An adequate history can provide useful clues to the cause of the eyelid malposition and may suggest the need for further evaluation. In some cases the history may make immediate surgical intervention unwise. The time of onset of the...

Trichilemmal Sebaceous Cyst

INTRODUCTION The trichilemmal cyst is also referred to as a sebaceous or pilar cyst. It is derived from the outer root sheath of the deeper parts of a hair follicle and consists of a well-keratinized epidermal wall surrounding semi-solid hair keratin and cholesterol-rich debris, rather than just sebaceous material. Trichilemmal cysts are more common in females and most cases occur in the sixth and seventh decades of life. They differ from epidermoid cysts in that they lack a granular layer in...

Anatomy of the Eyelids

The eyelids serve several valuable functions. Most importantly they provide mechanical protection to the globe. They also provide vital chemical elements to the precorneal tear film, and help distribute these layers evenly over the surface of the eye. During the blink phase the eyelids propel tears to the medial canthus where they enter the puncta of the lacrimal drainage system. The eyelashes along the lid margins sweep air-borne particles from in front of the eye, and the constant voluntary...

Nodular And Diffuse Dermatitis

Nodular and diffuse dermatitis represents a group of diverse inflammatory conditions, each of which presents with inflammatory cells present in nodules filling portions of the dermis or diffusely filling the entire dermis. As with all inflammatory patterns, there is significant overlap between nodular dermatitis and diffuse dermatitis many of the same diseases may present with either pattern. Similarly, cutaneous inflammatory conditions which are most often superficial or superficial and deep...

The Individual Cells of Hematopoiesis

Immature Red Cell Precursors Proerythroblasts and Basophilic Erythroblasts Proerythroblasts are the earliest, least mature cells in the erythrocyte-forming series erythropoiesis . Proerythroblasts are characterized by their size about 20 m , and by having a very dense nuclear structure with a narrow layer of cytoplasm, homogeneous in appearance, with a lighter zone at the center they stain deep blue after Romanowsky staining. These attributes allow proerythroblasts to be distinguished from...

Evaluation of Eyelid Lesions

The eyelids may be affected by benign and malignant lesions. Most of these are common elsewhere on the body, but when occurring on the eyelid they are often different in character, appearance, and behavior because of the unique characteristics of eyelid skin. A large number of cutaneous and systemic disorders may be associated with eyelid lesions. In many instances the eyelid findings are quite specific for a particular disorder, at other times they may be rather non-specific. These ocular...

Ferrans And Powers Quality Of Life Index

The Quality of Life Index QLI was developed by Ferrans and Powers to measure quality of life in terms of satisfaction with life. Quality of life is defined by Ferrans as a person's sense of well-being that stems from satisfaction or dissatisfaction with the areas of life that are important to him her. The QLI measures both satisfaction and importance of various aspects of life. Importance ratings are used to weight the satisfaction responses, so that scores reflect the respondents' satisfaction...

Chalazion and Hordeolum

INTRODUCTION A chalazion and hordeolum are focal inflammatory lesions of the eyelid that results from the obstruction of secretory glands. In a chalazion there is no acute bacterial infection, but rather a chronic inflammatory lesion with circumferential fibrosis. When this involves the meibomian glands they form a deep chalazion, whereas when there is involvement of the more superficial glands of Zeis in the dermis or glands of Moll associated with the pilosebaceous unit a more superficial...

Persistent snoring in a child is the main symptom of enlarged adenoids

In day-time there is mouth breathing. Purulent rhinorrhoea if there is secondary sinusitis and epistaxis also occur, with or without nasal symptoms. There is hearing loss due to otitis media with effusion, or earache from recurrent acute otitis media. Adenoids normally regress before puberty and adults with large adenoids are rare. If an adult has nasal obstruction due to postnasal lymphoid tissue, the histology is essential to exclude a lymphoma. Nasal obstruction may occur from birth due to...

The Tympanic Membrane and Middle

White areas of tympanosclerosis arrows are common findings on examination of the drum. They are of little significance in themselves, and the hearing is often normal. A past history of otorrhea in childhood or grommet insertion is usual. Chalk patches do occur with no apparent past otitis media. Extensive tympanosclerosis with a rigid drum is a sequela of past otitis media, and the ossicles, too, may be fixed or noncontinuous. Fig. 2.53 Scarring of the drum. a A...

Otoscopy Facial Nerve

The good fortune of otology resides in the fact that in most cases a diagnosis can be established through careful otoscopic examination the tympanic membrane is the window to the middle ear. Otoscopy constitutes the first phase in the examination of the patient. The initiation of the young otologist begins with this basic step. Colleagues of my generation will recall the long months of training which were necessary to understand and identify something in the depths of a narrow, tortuous, and...

Malignant Nasal Tumors

A nasal polyp that does not appear gray and opalescent should arouse suspicion, as should a polyp that bleeds spontaneously. A solid-looking hyperemic polyp may be an inverted papilloma. Granulation tissue in the nose may be malignant granuloma or carcinoma, and biopsy of any suspicious nasal lesion is necessary. Fig. 3.86 A pigmented polyp may be a Prognosis when radiotherapy is followed by maxillectomy is quite good for an early maxillary carcinoma, but poor when there is extensive invasion....

Surface Electromyography Evaluation

The abdominal and pelvic floor,the two channels of sEMG muscle activity, should be monitored simultaneously during the sEMG evaluation and the sEMG biofeedback-assisted pelvic muscle exercise training. Interpretative problems arise when monitoring only pelvic floor muscles without controlling changes in the intraabdominal pressure. The transmission of abdominal artifact to perennial measurements invalidates changes in the pelvic floor muscle measurements and can inadvertently reinforce...

Stab Wounds from Weapons Other than Knives

When an individual is stabbed with an implement other than a knife, the stab wound may have a characteristic appearance because of the unusual nature of the weapon. Because ice picks are no longer common household objects, ice pick wounds are rarely seen nowadays. Ice picks produce small, round, or slit-like wounds that can be easily missed or confused with wounds caused by .22-caliber bullets or shotgun pellets Figure 7.8 . A single ice pick wound might be missed on a cursory examination of a...

Essential Amino Acid Supplements

The building blocks of protein are called amino acids. Proteins are composed of long chains of amino acids, with the chains folded in complex ways. Twenty different amino acids that are used in building proteins are known. Almost all of these 20 amino acids are found in almost all proteins, in differing sequences. These different sequences cause the chains to fold in different ways, bringing about myriad different functions. Of these 20 amino acids, 12 can be synthesized by the body from...

Subacute Cutaneos Lupus Erythematosus Differential Diagnosis

Subacute CLE (SCLE) is an exanthematic skin condition with a typical clinical appearance (diagnosis can often be made before the presence of Ro SSA antibodies is documented) that is localized at the trunk and the extensor aspects of the upper extremities, more rarely in the face and neck (Sontheimer et al. 1979). Lesions have an intermediate morphology between DLE and SLE they are erythematous flat plaques, much thinner than DLE, with some dry scaling but without adherent scales and...

Inflammation nasal vestibulitis

Fig. 3.47 Vestibulitis presents as crusting and irritation in the anterior nares with resulting nasal obstruction. Examination shows excoriated vestibular skin and septal mucous membrane. Rubbing or over-diligent cleaning of the nose by the patient usually causes vestibulitis, particularly if, as in this case, the septum is deviated anteriorly and impinges on the lateral wall of the nose. Advice and the use of antibiotic and corticosteroid ointment are effective in controlling vestibulitis....

How to Perform the Best Peeling for the Treatment of Rosacea

Salicylic acid peelings performed at 3- to 4-week intervals are a good choice for patients with rosacea. Salicylic acid peeling has antimicrobial activity, reduces erythrosis and prevents relapses. In erythrosis 15 to 25 to 30 salicylic acid peeling should be performed at 3-week intervals for a total of three to four peelings (Fig. 17.14a, b). Suggested topical treatment between peeling includes 0,75 metronidazole cream once a day or 1-2 salicylic acid cream once a day and sunblock creams In...

Intracranial Hypertension

The normal intracranial pressure ICP is 60-120 mmH2O, which corresponds to 5-15 mmHg. An ICP greater than 30 mmHg impairs cerebral blood flow an ICP greater than 50 mmHg for more than 30 minutes is fatal an ICP greater than 80 mmHg for any length of time can cause brain damage. Intracranial hypertension may be either acute developing in hours to days or chronic lasting for weeks or months . Its manifestations are progressively more severe as the ICP rises, but are not specific thus, the...

Overview of Treatment Approach Acceptance Theory and Intervention

The following section provides detailed information about how to use ACT in a clinical setting. There are several main goals that are generally presented in order when using ACT. This is not to say, however, that the ACT goals cannot be presented in a different order, or that the ACT therapist cannot choose to emphasize one goal over another, depending on the client's specific issues. ACT is diverse and flexible and allows for a range of concepts to be presented depending on client needs. Here...

Inflammation of the Larynx Laryngitis

Whether acute or chronic, laryngitis presents with hoarseness and generalized hyperemia of the laryngeal mucous membrane. Acute laryngitis commonly follows an upper respiratory tract infection, or is traumatic following vocal abuse. Voice rest is the most effective treatment. Chronic laryngitis may be associated with infection in the upper or lower respiratory tract, but is commonly irritative due to occupation and environment, vocal abuse, or tobacco. The unusual laryngitis of myxoedema must...

Retinal anatomy and physiology

If one were to observe a normal human retina through an ophthalmoscope, one would see the gross morphological features illustrated in Figure 11.2. On the right side of the figure is the head of the optic nerve, also called the optic disk. A number of blood vessels originate from approximately the center of the optic disk and spread to cover much of the inner retina the side of the retina closest to the lens . These vessels are supplied by the central artery and vein of the retina, which pass...
