Rupture of the membranous urethra is supposed to be demonstrated on rectal examination by a boggy swelling and high-riding prostate skin care 4 less order curatane without a prescription. The mechanism of injury and the clinical signs suggest the possibility of urethral injury skin care acne buy curatane overnight. Management the immediate management of urethral trauma is to drain the bladder and bypass the injury skin care 15 days before marriage purchase curatane overnight. In all cases of total rupture acne scar laser treatment buy cheap curatane 5mg on line, and in cases of partial rupture when urethral catheterization is found to be impossible, drainage should be accomplished by means of a percutaneous suprapubic catheter. This procedure may be difficult if there is a large pelvic haematoma and if the bladder is not distended. It is best performed under ultrasound guidance and may have to be done by open surgery. Many advocate a repeat urethrogram 6 or 8 weeks after the injury to delineate the injury accurately, followed by elective surgical repair 3 months after the initial episode. Injuries of the bulbar and membranous urethra are normally amenable to repair by excision and anastomosis of the scarred disrupted segment. Injuries of the penile urethra or any long segment are challenging and may require reconstructive flaps or grafts as described above for urethral stricture (see page 515). Imaging Diagnosis is made by an ascending urethrogram, as described above for urethral stricture (see page 515). With the patient in an oblique position, contrast is instilled into the urethra and images are taken of its whole length. Diseases of the external genitalia are frequently encountered by physicians working in almost all areas of clinical practice. The key to an accurate diagnosis of the cause of the presenting problem is a careful, systematic clinical examination, but a good understanding of the underlying pathological processes is also essential to guide correct investigation and treatment. Patients with a recurrent balanoposthitis will have a history of episodes of pain and discharge from beneath the foreskin. Sexual function may be affected because of pain or splitting of the foreskin during an erection. The severity of the phimosis can be detected on examination by attempting to retract the foreskin as far as possible. When severe phimosis or adhesions prevent retraction, the glans penis should be carefully palpated through the prepuce for any swelling suggestive of a carcinoma. Enlarged or tender inguinal lymph nodes suggest the presence of cancer or infection. A tight foreskin once retracted may present acutely as a paraphimosis (see below). Abnormal micturition the urethra usually ends on the tip of the glans penis but it may, if there is a defect in its intrauterine development, open anywhere on the ventral surface A non-retractable foreskin An inability to pull the prepuce back over the underlying glans penis is most often caused by a congenitally narrow opening at its end, a phimosis. If a congenital phimosis is very tight, the patient or their parents will complain of ballooning of the foreskin or spraying of the urinary stream during micturition. Swellings in the scrotal skin and within the scrotum the common causes of swellings in the scrotal skin and within the scrotum are: Ulcers or lumps on or in the penis Possible causes of ulcers and lumps on the penis are: sebaceous cysts scrotal carcinoma hydrocele varicocele epididymal cysts tumours of the testis. It is vitally important to distinguish between benign and malignant or pre-malignant conditions. The duration of symptoms is an important clinical feature, together with the presence or absence of pain or urethral discharge. In cases of malignancy, weight loss and anorexia may indicate disseminated disease. Some infective lesions will be acquired sexually, for example syphilis and herpes simplex, so a detailed sexual history must be taken. Penile cancer which is unusual in younger men may present as a small papillary or ulcerated lesion, or a fungating mass. A syphilitic chancre begins as an erythematous, papular lesion and then becomes a painless, All the above can usually be diagnosed by a careful clinical examination. The skin of the scrotum is so mobile that it is usually obvious when a swelling is actually in the scrotal skin or deep to it. Sebaceous cysts in the scrotal skin become painful when infected or are complicated by abscess formation. Varicoceles may give rise to an aching discomfort, particularly after long periods of standing. Epididymal cysts, uncomplicated hydroceles and most testicular tumours present as painless swellings but some testicular cancers are associated with acute pain and swelling. Varicoceles and epididymal cysts may be palpably separate from the testes, whereas testicular cancers and hydroceles cannot be felt separately. An acutely painful, swollen, erythematous scrotum indicates a different underlying problem (see below). Pain caused by torsion is usually rapid in onset, whereas the pain from infection tends to build up slowly. It should be remembered that some testicular cancers can present with acute pain and swelling. In testicular torsion the testis is classically riding high, lying transversely and exquisitely tender. Torsion and epididymo-orchitis often need to be separated by urinalysis, culture of the urine, blood tests and ultrasound imaging to distinguish between torsion and infection. Microbiology Swabs should be taken of any discharge for microbiological examination. Tissue biopsy An absent testicle the diagnosis is obvious and invariably made by the patient. In the adult patient, a careful history must be taken to distinguish between a retractile testis, in which an active cremasteric reflex causes the testis to sometimes retract up into the inguinal canal, a true undescended testis (cryptorchidism) and an atrophic testis.

The murmur of congenital pulmonic stenosis is in the right second intercostal space acne 3 step clinique buy cheap curatane on-line. Mitral valve prolapse causes a late systolic murmur usually introduced by an ejection click. Chronic mitral regurgitation causes a holosystolic murmur that radiates to the apex. Indications for intervention for descending dissections acutely include occlusion of a major aortic branch with symptoms. For example, paralysis may occur with occlusion of the spinal artery or worsening renal failure may occur in the case of dissection that involves the renal arteries. Once a descending dissection has been found, intensive medical management of blood pressure is imperative and should include agents that decrease cardiac contractility and aortic shear force. Most commonly, electrolyte disturbances such as hypokalemia and hypomagnesemia, phenothiazines, fluoroquinolones, antiarrhythmic drugs, tricyclic antidepressants, intracranial events, and bradyarrhythmias are associated with this malignant arrhythmia. Management, besides stabilization, which may require electrical cardioversion, consists of removing the offending agent. There are varying P-wave morphologies (more than three morphologies) and P-P intervals. Anemia, pain, and myocardial ischemia are also causes of tachycardia that should be considered when managing a new tachycardia. If an anticoagulant is added, enoxaparin has been shown to be superior to unfractionated heparin in reducing recurrent cardiac events. Eptifibatide, tirofiban, and abciximab are beneficial for patients likely to receive percutaneous intervention. Patients with wide complex tachycardia suggestive of ventricular tachycardia or known preexcitation syndrome should be treated with agents that decrease automaticity, such as quinidine and procainamide. However, in patients with apparent ventricular tachycardia who have neither a history of ischemic heart disease nor preexcitation syndrome, adenosine may be a useful diagnostic agent to determine whether a patient has a reentrant tachycardia, in which case the drug may terminate it; an atrial tachycardia, in which case the atrial activity may 81. Although adenosine is not the recommended primary therapy for patients with wide complex tachyarrhythmia, patients with junctional tachycardia who have evidence of poor ventricular function or concomitant -adrenergic blockade may be reasonable candidates for its use. The risk of rupture and subsequent management are related to the size of the aneurysm as well as symptoms related to the aneurysm. When symptoms do occur, they are frequently related to mechanical complications of the aneurysm causing compression of adjacent structures. This includes the trachea and esophagus, and symptoms can include cough, chest pain, hoarseness, and dysphagia. Beta blockers are recommended because they decrease contractility of the heart and thus decrease aortic wall stress, potentially slowing aneurysmal growth. Individuals with thoracic aortic aneurysms should be monitored with chest imaging at least yearly, or sooner if new symptoms develop. Operative repair is indicated if the aneurysm expands by >1 cm in a year or reaches a diameter of >5. Endovascular stenting for the treatment of thoracic aortic aneurysms is a relatively new procedure with limited long-term results available. The largest study to date included >400 patients with a variety of indications for thoracic endovascular stents. However, if the procedure was done emergently, the mortality rate at 30 days was 28%. At 1 year, data were available on only 96 of the original 249 patients with degenerative thoracic aneurysms. Ongoing studies with long-term follow-up are needed before endovascular stenting can be recommended for the treatment of thoracic aortic aneurysms, although in individuals who are not candidates for surgery, stenting should be considered. Acute pericarditis is the most common disease of the pericardium and typically presents as a sharp, intense anterior chest pain. It may be referred to the neck, arms, or left shoulder and may be pleuritic in nature. The pain is worse with lying supine and improved with sitting up and leaning forward. A pericardial friction rub is described as high-pitched, grating, or scratching and is heard throughout the cardiac cycle. An echocardiogram should be performed if there is suspicion of a possible effusion. Aspirin or nonsteroidal antiinflammatory drugs in high doses are most commonly used. As this patient is in severe pain, reassurance only is not the best option but would be a possible treatment if panic attack were suspected. The other choices are utilized in the case of unstable angina and acute myocardial infarction and should not be utilized in this patient. Both heparin and reteplase would increase the risk of developing a hemorrhagic pericardial effusion. Although all of the diagnoses listed are causes of sudden cardiac death in young individuals, commotio cordis is the likely diagnosis because of the occurrence of the injury in relation to blunt trauma to the chest wall. Furthermore, this artery in the majority of 586 Review and Self-Assessment In contrast to cardiac contusion (contusion cordis), the force of the injury is insufficient to cause cardiac contusion or injury to the ribs or chest wall.

Peripartum cardiomyopathy is far more common in Africa than in North America or Europe; the incidence has been reported to be especially high in Nigeria. Pathogenetic factors that may be operative include low socioeconomic status, high parity, prolonged lactation, excessive dietary salt intake, and selenium deficiency. J Am Coll Cardiol 42:1688, 2003 - et al: Contemporary definitions and classification of the cardiomyopathies: An American Heart Association Scientific Statement. However, thiamine deficiency in the West may occur in patients with severe alcoholism. So-called wet beri-beri heart disease is an important clinical manifestation of serious thiamine deficiency. It is characterized by cardiac failure secondary to a high cardiac output state caused by arteriolar vasodilation; it is associated with tachycardia, wide pulse pressure, a third heart sound, and warm extremities. The response to thiamine is usually dramatic, but it should be accompanied by diuretics. The normal pericardium, by exerting a restraining force, prevents sudden dilation of the cardiac chambers, especially of the right atrium and ventricle, during exercise and with hypervolemia. It also restricts the anatomic position of the heart, minimizes friction between the heart and surrounding structures, prevents displacement of the heart and kinking of the great vessels, and probably retards the spread of infections from the lungs and pleural cavities to the heart. Notwithstanding the foregoing, total absence of the pericardium, either congenital or following surgery, does not produce obvious clinical disease. In partial left pericardial defects, the main pulmonary artery and left atrium may bulge through the defect; very rarely, herniation and subsequent strangulation of the left atrium may cause sudden death. Pain, a pericardial friction rub, electrocardiographic changes, and pericardial effusion with cardiac tamponade and paradoxical pulse are cardinal manifestations of many forms of acute pericarditis. Chest pain is an important but not invariable symptom in various forms of acute pericarditis (Chap. Pain is often absent in slowly developing tuberculous, postirradiation, neoplastic, or uremic pericarditis. The pain of acute pericarditis is often severe, retrosternal and left precordial, and referred to the neck, arms, or the left shoulder. Characteristically, however, pericardial pain may be relieved by sitting up and leaning forward and is intensified by lying supine. Posttraumatic a this dissociation is useful in the differentiation between 255 these conditions. The pericardial friction rub, audible in about 85% of patients, may have up to three components per cardiac cycle, is high-pitched, and is described as rasping, scratching, or grating (Chap. It is heard most frequently at end-expiration with the patient upright and leaning forward. The rub is often inconstant, and the loud to-and-fro leathery sound may disappear within a few hours, possibly to reappear on the following day. A pericardial rub is heard throughout the respiratory cycle, while a pleural rub disappears when respiration is suspended. Pericardial effusion is especially important clinically when it develops within a relatively short time as it may lead to cardiac tamponade (see later). Differentiation from cardiac enlargement may be difficult on physical examination, but heart sounds may be fainter with pericardial An autosomal recessive syndrome, characterized by growth failure, muscle hypotonia, hepatomegaly, ocular changes, enlarged cerebral ventricles, mental retardation, ventricular hypertrophy, and chronic constrictive pericarditis. The friction rub may disappear, and the apex impulse may vanish, but sometimes it remains palpable, albeit medial to the left border of cardiac dullness. The chest roentgenogram may show a "water bottle" configuration of the cardiac silhouette. The frame is recorded in early ventricular systole, immediately after atrial contraction. Note that the right atrial wall is indented inward and its curvature is frankly reversed (arrow), implying elevated intrapericardial pressure above right atrial pressure. When severe, the extent of this motion alternates and may be associated with electrical alternans. Echocardiography allows localization and estimation of the quantity of pericardial fluid. These techniques may be superior to echocardiography in detecting loculated pericardial effusions, pericardial thickening, and the presence of pericardial masses. The three most common causes of tamponade are neoplastic disease, idiopathic pericarditis, and pericardial effusion secondary to renal failure. Tamponade may also result from bleeding into the pericar- 257 dial space either following cardiac operations and trauma (including cardiac perforation during cardiac catheterization, percutaneous coronary intervention, or insertion of pacemaker wires) or from tuberculosis and hemopericardium. The latter may occur when a patient with any form of acute pericarditis is treated with anticoagulants. The quantity of fluid necessary to produce this critical state may be as little as 200 mL when the fluid develops rapidly or >2000 mL in slowly developing effusions when the pericardium has had the opportunity to stretch and adapt to an increasing volume. The volume of fluid required to produce tamponade also varies directly with the thickness of the ventricular myocardium and inversely with the thickness of the parietal pericardium. Tamponade may also develop more slowly, and under these circumstances the clinical manifestations may resemble those of heart failure, including dyspnea, orthopnea, and hepatic engorgement. A high index of suspicion for cardiac tamponade is required since, in many instances, no obvious cause for pericardial disease is apparent, and it should be considered in any patient with hypotension and elevation of jugular venous pressure.

Although it is possible to assess power exhaustively in many other limb muscles acne around mouth buy 30mg curatane fast delivery, selection is required skin care kiehls buy genuine curatane. This is generally governed by information already available from the history acne popping buy 20mg curatane, or from other parts of the examination skin care 1 month before wedding discount 20mg curatane overnight delivery, whereby a particular pattern of focal weakness may have suggested itself. Anatomical localization is then achieved once again by discriminating between very few options as shown for the very common clinical problems of wrist and foot drop. Likewise, the history may have pointed to a lesion of an individual cervical spinal segment (neck pain radiating down one arm), again a very common clinical situation (Chapter 15). The descending inhibitory pathways mainly act on the gamma efferents (not shown) which modulate the sensitivity of the stretch receptors. Other forms of increased tone, caused by extrapyramidal disease, are described in Chapter 12. An affected limb will first pronate then drift downwards (pronator or pyramidal drift sign). Disease of other parts of the nervous system may also be identified by asking the patient to perform this simple manoeuvre. For example, a patient with loss of joint position sense in the hands may show irregular involuntary movements of the fingers when the arm is outstretched and the eyes 38 Motor function Chapter 5 detect a pattern of weakness corresponding to the muscles innervated by a single segmental nerve, its myotome (Table 5. Thus, primary muscle disease is typically associated with proximal weakness whereas a motor polyneuropathy usually produces distal weakness. By this is meant greater weakness of extensors than flexors in the upper limbs and of flexors than extensors in the lower limbs. Thus, a patient who is hemiparetic after a vascular event in one cerebral hemisphere will typically have a flexed arm and extended leg on the opposite side of the body from the brain lesion. Cerebellar disease leads to inaccuracy in this test (past-pointing) because of inability to judge distances (dysmetria). As the finger approaches the target, it may oscillate increasingly wildly (intention tremor). An alternative test is to ask the patient to perform rapid alternating movements. Much may also be learnt from assessment of muscle tone, which may be reduced in cerebellar disease, from the reflexes (see below) and from examining: gait (see below), Coordination Lack of coordination, or ataxia, is often considered synonymous with cerebellar disease. But, as previously stated, coordinated movement requires the normal action of all the components of the motor system and of parts of the sensory system, particularly joint position sense. In the hand, this may have as damaging an effect on useful movement as severe muscle weakness. Formal tests of coordination in the limbs may, however, provide localizing information on cerebellar disease, the lesion generally being in the cerebellar hemisphere on the same side as the abnormal sign. Reflexes Tendon reflexes these are a direct method of testing the immediate action of the stretch reflex clinically. Striking the tendon of a muscle with a patellar hammer will stretch the muscle passively and induce reflex contraction. Sometimes a reflex that initially appears 39 Chapter 5 Motor function Shoulder abduction Deltoid Axillary nerve C5 Elbow flexion Biceps Musculocutaneous nerve C5, C6 Elbow extension Triceps Radial nerve C7 Wrist extension Extensors carpi radialis, C6 and ulnaris, C7, Radial nerve Wrist flexion Flexors carpi radialis, C7, median nerve and ulnaris, C8, ulnar nerve Finger extension Extensor digitorum Radial nerve C7 Finger flexion Flexors digitorum profundus and superficialis Median and ulnar nerves C8 Thumb abduction Abductor pollicis brevis Median nerve T1 Finger abduction Dorsal interossei Ulnar nerve T1 Figure 5. For each movement, the relevant muscle, peripheral nerve and main root value are given. This phenomenon of reinforcement is due to such manoeuvres increasing the sensitivity of stretch receptors throughout the body. This is also due to loss of supraspinal inhibition, the sharp muscle stretching, leading to oscillation within the circuit of the reflex arc. Clonus may be sustained or may 40 Motor function Chapter 5 Hip flexion Iliopsoas Lumbar plexus and femoral nerve L1/L2 Hip extension Gluteus maximus Inferior gluteal nerve L5, S1, S2 Knee flexion hamstrings Sciatic nerve L5, S1, S2 Knee extension Quadriceps femoris Femoral nerve L3, L4 Ankle dorsiflexion Tibialis anterior Deep peroneal nerve L4, L5 Ankle plantar flexion Gastrocnemius and soleus Sciatic nerve S1, S2 Dorsiflexion of great toe Extensor hallucis longus Deep peroneal nerve L5 Ankle inversion Tibialis posterior Tibial nerve L4, L5 Ankle eversion Peronei Superficial peroneal nerve L5, S1 Figure 5. Clonus at sites other than the ankles (knees, fingers) is also generally pathological. Thus, for example, a lesion of the spinal cord at C5/6 may abolish the biceps and the Table 5. Tendon reflexes may possess qualities indicative of disease processes other than those directly affecting the motor neurones. Cutaneous reflexes the cutaneous reflexes most often of value clinically are the plantar and superficial abdominal responses. The superficial abdominal responses are elicited by a swift stroke with an orange stick horizontally across the skin of each abdominal quadrant. The superficial abdominal responses may also be absent in obese patients, in those with abdominal scars and after repeated pregnancy. Neck and trunk Neck flexion is achieved by simultaneous contraction of both sternomastoid muscles, Table 5. Weakness of neck extension, such that the patient has to support his or her head with hand under chin, is relatively uncommon, but occurs in: myasthenia gravis (Chapter 17), polymyositis (Chapter 17), Truncal ataxia is particularly associated with damage to cerebellar midline (vermis) structures. It may be so severe that the patient is unable to maintain a stable sitting posture unsupported. Gait and stance Certain gaits are associated with specific neurological disorders (Table 5. Truncal weakness, detected by asking the patient to rise unaided from a lying to a sitting position with arms folded, may occur as part of a more generalized proximal weakness, as seen in primary muscle disease.
