Urinary tract symptoms Pain Afferent innervation of the urinary tract is rudimentary, and as such pain originating from these organs, though characteristic, may not easily be localised. Renal pain occurs in the angle between the 12th rib and the sacrospinalis muscles. Ureteric pain (or colic) typically radiates forwards and downwards towards the groin, testes or labia, following the dermatomes relating to the nerve roots from which the sympathetic innervation of the ureter originates. A prostate that is grossly enlarged can cause rectal symptoms, including tenesmus. Haematuria, or the presence of blood in the urine, is a very specific symptom of urinary tract disease. It may be nonvisible, where the urine appears clear on naked eye examination but contains red blood cells on microscopic examination. Visible haematuria is the condition in which the urine is red or brown in colour, and occurs when there is substantial bleeding in the urinary tract. The haematuria may be intermittent in frequency with periods of clear urine in between, or it may be persistent. It may be present either throughout the act of micturition or only during a particular phase of micturition, providing a clue to the aetiology (Table 23. Conditions that may mimic haematuria are discoloration of urine due to certain drugs like phenazopyridine and rifampicin, or certain food items like beetroot. They are of no clinical significance other than that they may cause undue anxiety to the patient. Dysuria Dysuria or painful micturition is often described by the patient as a sensation of burning during micturition. It is usually localised to the urethra and is associated with acute inflammatory conditions of the lower urinary tract. Frequency, nocturia, urgency these symptoms are interrelated and are the result of inability of the bladder to hold urine. Frequency may be caused by an actual decrease in the capacity of the bladder (due to diseases causing fibrosis) or by a decrease in the functional capacity of the bladder (due to a large residual volume of urine). Acute inflammatory conditions also decrease the capacity of the bladder and lead to frequency and inability to postpone micturition (urgency). Nocturia or night-time frequency may be a result of renal disorders leading to a decrease in the concentrating ability of the kidney, or due to excessive intake of fluids, caffeine or alcohol before bedtime. Frequency is recorded numerically: D/N 6/3 (by day, six times; by night, three times). Stress incontinence occurs with any increase in the intravesical pressure (straining, coughing, laughing) and leads to a loss of urine due to a weakness of the sphincter mechanism. Urge incontinence is associated with urgency and is seen in acute inflammatory conditions, patients with upper motor neuron injuries and in individuals with an overactive bladder. Overflow incontinence is seen in patients with chronic urinary retention, when urine dribbles out of the bladder due to an excessive rise in intravesical pressure.
Management Acute abscesses Surgical drainage is indicated for established abscess and the incision should avoid the midline to minimise recurrence gastritis diet of worms order generic prevacid pills. Antibiotics have a place in the early stages of abscess formation and may avert the need for incision and drainage of an established abscess gastritis diet íôòâó÷þêã 30mg prevacid otc. Chronic discharging disease Nonoperative approach Pilonidal disease treatment may be conservative or surgical gastritis with duodenitis purchase prevacid overnight delivery. Conservative management comprises attention to natal cleft hygiene and hair removal by depilatory creams or by careful shaving. Hair removal from the sinus tract itself on a regular basis allows the sinus to drain and avoids the collection of hair and debris. The superficial part of the midline sinus is lined with squamous epithelium, but the tracts are lined with granulation tissue due to chronic infection. It is more common in males than females, and affects around 2% of the population between the ages of 15 and 35 years. The disease is rare before puberty, when sex hormones act on hair follicles and sebaceous glands, and after the age of 40, suggesting that there is an aetiological relationship with age and skin character. Operative procedures Debilitating, chronically discharging sinus tracts merit surgery. Tracts are laid open, granulation tissue removed with a curette and allowed to heal from the base. Asymmetric (off midline) closure is associated with faster healing and less recurrence. Recurrence is common, due partly to inadequate or inappropriate surgery in some cases, but mostly due to the fact that the underlying aetiology remains: namely, the natal cleft and a predisposed skin type. Recurrent disease can be treated using rotation flaps to replace the pitted skin with fresh skin from the buttock (Karydakis procedure). For complex recurrent disease, ablation of the natal cleft using a flap procedure (cleft closure) is highly effective but leaves a fairly large unsightly scar. Pathogenesis Pilonidal disease, although initially thought to be congenital, is an acquired condition. Hair follicle enlargement, secondary to repeated friction, allows the accumulation of extraneous hairs that are caught in the natal cleft. A foreign-body reaction occurs leading to a chronic discharging sinus that attracts other debris and hairs. Risk factors A sedentary occupation, particularly where sweating is common, is a predisposing factor. The condition was described in large numbers of American troops in the Vietnam war, owing to the use of Jeeps in the warm climate. Clinical features Many people have asymptomatic pilonidal sinuses and so it is important to treat the condition only if it is causing problems, in view of the high prevalence and the fact that it seldom presents Section 3 Surgical specialties Plastic surgery including common skin and subcutaneous lesions 301 the breast 326 Endocrine surgery 351 Vascular and endovascular surgery 375 Cardiothoracic surgery 409 Urological surgery 429 Neurosurgery 461 Transplantation surgery 487 Ear, nose and throat surgery 502 Orthopaedic surgery 528 this page intentionally left blank Patrick Addison Plastic surgery including common skin and subcutaneous lesions Chapter contents Introduction 301 Structure and function of the skin 301 Wounds 301 Burns 308 Skin and soft tissue lesions 315 18 Introduction Reconstructive plastic surgery, as opposed to cosmetic surgery, is concerned with the restoration of form and function following trauma, ablative surgery, necrotising infection or congenital anomaly. The various techniques by which this is achieved are applicable throughout the body whether male or female, young or old, and the surgeon must therefore have an excellent knowledge of applied anatomy and reconstructive techniques. The specialty is highly varied and includes the surgical management of skin and soft tissue malignancy; soft tissue trauma; breast, trunk and perineal reconstruction; burns; soft tissue infection; hand surgery, brachial plexus and nerve compression; facial reanimation; cleft lip and palate and craniofacial deformity; and cosmetic surgery. The dermis, which is bound to the epidermis through a basement membrane, is composed of three cell types (fibroblasts, macrophages and adipocytes), collagen, elastic fibres and an extracellular gel-like matrix. It supports the blood vessels, lymphatics, nerves and the epidermal appendages as well as pressure and temperature receptors. At the junction between the epidermis and the superficial papillary dermis, vascularised papillae push upwards to nourish the epidermis. Beneath this, the reticular dermis provides the strength and elasticity of the skin.

Motor responses originating in the brainstem are more complex gastritis diet 6 meals discount prevacid 15 mg with mastercard, whereas the most complicated and precise motor responses originate from the cerebral cortex gastritis diet management purchase 30mg prevacid overnight delivery. Anterior motor neurons in the anterior horns of the spinal cord gray matter give rise to A-a fibers that leave the spinal cord by way of anterior nerve roots and innervate skeletal muscles chronic gastritis with h pylori purchase prevacid 15 mg line. Skeletal muscles and tendons contain muscle spindles and Golgi tendon organs that operate at a subconscious level to relay information to the spinal cord and brain relative to changes in length and tension of skeletal muscle fibers. The stretch reflex is a reflex contraction of the skeletal muscle whenever stretch of the opposite balanced muscle results in stimulation of the muscle spindle. Tapping the patellar tendon elicits a k nee jerk, which is a stretch reflex of the quadriceps femoris muscle. For example, lesions in the contralateral motor areas of the cerebral cortex, as caused by a cerebral vascular accident or brain tumor, cause greatly enhanced stretch reflexes. This phenomenon typically occurs when the stretch reflex is sensitized by facilitatory impulses from the brain, resulting in exaggerated facilitation of the spinal cord. When associated with recovery from general anesthesia, clonus as initiated by abrupt dorsiflexion of the foot can be eliminated by flexing the knees and keeping them in a flexed position. Lower motor neurons originate in the spinal cord and directly innervate skeletal muscles. A lower motor neuron lesion is associated with flaccid paralysis, atrophy of skeletal muscles, and absence of stretch reflex responses. Spastic paralysis with accentuated stretch reflexes is due to destruction of upper motor neurons in the brain. Upper motor neurons originate in the cerebral cortex or brainstem and traverse down the anterior and lateral corticospinal paths until they connect with the lower motor neuron in the ventral horn of the spinal cord. Withdrawal flexor reflexes are a lower motor neuron reflex, typically elicited by a painful stimulus. These nerves are familiar to anesthesiologists as the targets for regional anesthetic techniques, and the anatomy is well reviewed in many atlases of regional anesthesia. Pathways for Peripheral Sensory Impulses the peripheral nerves extend from the dendrite in the periphery to the dorsal root ganglion, where the cell body is located, and from there to the spinal cord by way of the dorsal root. By definition, dendrites conduct impulses toward the cell body, whereas axons conduct impulses away from the cell body. Thus, the portion of the nerve from the cell body to the peripheral receptor is a dendrite, whereas the relatively shorter connection from the dorsal root ganglion to the spinal cord is the axon. However, structurally, the dendrite and the axon are indistinguishable, and the nerve behaves like one long axon, giving rise to the term pseudounipolar neuron that occasionally is used to describe peripheral nerves. After entering the spinal cord, peripheral sensory neurons synapse in the dorsal horn and give rise to long, ascending fiber tracts that transmit sensory information to the brain. These sensory signals are transmitted to the brain by the dorsal-lemniscal system, which includes dorsal column pathways and spinocervical tracts, and by anterolateral spinothalamic tracts. Synapses in the thalamus are received by neurons that project into the somatic sensory area of the cerebral cortex. Nerve fibers of the anterolateral spinothalamic system cross in the anterior commissure to the opposite side of the spinal cord, where they turn upward toward the brain as the ventral and lateral spinothalamic tracts. Sensory signals from the anterolateral spinothalamic system are relayed from the thalamus to the somatic sensory area of the cerebral cortex. The delayed onset of the cross-extensor reflex is due to the time necessary for the signal to pass through the additional neurons to reach the opposite side of the spinal cord. Autonomic Nervous System the autonomic nervous system controls the visceral functions of the body. In addition, the autonomic nervous system modulates systemic blood pressure, gastrointestinal motility and secretion, urinary bladder emptying, sweating, and body temperature maintenance. Soma of sensory neuron Gray matter White matter Dorsal root Dorsal root ganglion Soma of motor neuron Ventral root Spinal nerve autonomic nervous system occurs principally via centers located in the hypothalamus, brainstem, and spinal cord.
