Rarely acticoat 7 antimicrobial dressing generic zithrogen 100 mg otc, the subclavian vein may be obstructed with swelling of the arm and subclavian vein thrombosis topical antibiotics for acne list discount 250mg zithrogen otc. A Doppler ultrasound might help to elucidate the actual abnormality in the subclavian artery antibiotic 93 2264 discount zithrogen 500 mg on-line. Involvement of the endothelium with neutrophil infiltrates leads to thrombosis and obliteration of the lumen antibiotic after tooth extraction discount 250mg zithrogen with visa. Total abstinence from smoking is mandatory; this will arrest although not reverse the disease. Sympathectomy relieves the rest pain because there is an element of vasospasm in the diseased vessels; the procedure might also help to heal distal patches of skin necrosis and nailbed infection. E Perforating veins (perforators) joining the superficial and deep veins of the calf have valves. B In ultrasound-guided foam sclerotherapy in a single session the maximum volume should be no more than 20 mLs. D Endovenous interventions may result in thromboembolic and phlebitic complications. The following statements are true except: A the capillaries have a pressure of 32 mmHg at the arterial end and 12 mmHg at the venular end. C Patent deep veins, perforators and superficial veins, all with competent valves, are necessary to keep the venous pressure down to normal. A the three factors in venous thrombosis are endothelial damage, stasis and thrombophilia B Deficiencies of antithrombin, activated protein C and protein S predispose to venous thrombosis. On examination she has large varicosities along the medial side of her entire left lower limb. This has been there almost all his life, is painless and feels soft and compressible. A 74-year-old man complains of a tender cord-like structure along the medial side of his entire right lower limb of two months duration. A 65-year-old man who underwent an anterior resection for rectal cancer complains of pain in his left calf on the first postoperative day. On examination he has low-grade pyrexia and the calf looks swollen with shiny skin and is tender. A 72-year-old woman complains of an ulcer on the medial side of her left leg over 5 months. Many years ago she suffered from recurrent swollen legs following the birth of her three children, who are now in their forties. On examination there is marked uniform swelling of his right upper limb, extending from the supraclavicular region. G A 28-year-old man complains of extensive varicose veins on the outer side of his entire left lower limb, where he has had a prominent big vein over the whole leg. Since he was a teenager, his left lower limb has felt larger than the right and has a large capillary naevus. F A 38-year-old man complains of marked swelling of his entire right upper limb of 24 hours Answers to multiple choice questions 1. This anatomical landmark is important when making an incision to perform groin dissection for varicose vein surgery. This anatomical fact is important when performing a venous cut-down for open intravenous access and not to strip a varicose vein down to the ankle. It ascends along the lateral edge of the Achilles tendon in the subcutaneous fat covered by skin and superficial fascia. In its ascent, it passes between the two heads of the gastrocnemius to terminate in the popliteal vein above the knee joint. In the calf and thigh, there are several perforating veins with valves that join the superficial to the deep venous system. In the upper limb, the axillary vein is not formed by the union of the basilic and cephalic veins. The basilic vein drains the medial side of the forearm and hand, piercing the deep fascia at the elbow where it joins the venous tributaries of the brachial artery to form the axillary vein. The cephalic vein ascends along the lateral aspect of the forearm and arm and empties into the axillary vein after piercing the deltopectoral fascia in the deltopectoral groove.

Mechanism of Injury Force is directed against the posterior aspect of an elbow flexed 90 degrees antibiotic resistant organisms cheap zithrogen 100mg amex, thus driving the ulna into the trochlea antimicrobial proteins purchase generic zithrogen. Treatment Treatment must be individualized according to patient age antibiotics for acne mayo clinic order 250 mg zithrogen, bone quality antibiotics for dogs for uti discount zithrogen 500mg fast delivery, and degree of comminution. Chapter 17 Distal Humerus 221 Nonoperative this is indicated for nondisplaced fractures, elderly patients with displaced fractures and severe osteopenia and comminution, or patients with significant comorbid conditions precluding operative management. Nonoperative options for displaced fractures include Cast immobilization: this has few advocates; it represents the "worst of both worlds"-inadequate fracture reduction and prolonged immobilization. Operative Open reduction and internal fixation the indication is a displaced reconstructible fracture. Goals of fixation are to restore articular congruity and to secure the supracondylar component. Methods of fixation Interfragmentary screws Dual plate fixation: one plate medially and another plate placed posterolaterally, 90 degrees from the medial plate or two plates on either column, 180 degrees from one another Total elbow arthroplasty (cemented, semiconstrained): this may be considered in markedly comminuted fractures and with fractures in osteoporotic bone. Postoperative care: Early range of motion of the elbow is essential unless fixation is tenuous. Complications Posttraumatic arthritis: this results from articular injury at time of trauma as well as a failure to restore articular congruity. Loss of motion (extension): this is increased with prolonged periods of immobilization. Range-of-motion exercises should be instituted as soon as the patient is able to tolerate therapy, unless fixation is tenuous. Neurologic injury: (Up to 15%) the ulnar nerve is most commonly injured during surgical exposure. Condylar Fractures these are rare in adults and are much more common in the pediatric age group. Less than 5% of all distal humerus fractures are condylar; lateral fractures are more common than medial. Medial condyle fractures: these include the trochlea and medial epicondyle and are less common than medial epicondylar fractures. Mechanism of Injury Abduction or adduction of the forearm with elbow extension Classification Milch Two types are designated for medial and lateral condylar fractures; the key is the lateral trochlear ridge. They may allow for radioulnar translocation if capsuloligamentous disruption occurs on the contralateral side. Jupiter this is low or high, based on proximal extension of fracture line to supracondylar region. Indicated for nondisplaced or minimally displaced fractures or for patients with displaced fractures who are not considered candidates for operative treatment. It consists of posterior splinting with the elbow flexed to 90 degrees and the forearm in supination or pronation for lateral or medial condylar fractures, respectively. Consists of screw fixation with or without collateral ligament repair if necessary, with attention to restoration of the rotational axes. Prognosis depends on the degree of comminution the accuracy of reduction the stability of internal fixation Range-of-motion exercises should be instituted as soon as the patient can tolerate therapy. Nonoperative Operative Complications Lateral condyle fractures: Improper reduction or failure of fixation may result in cubitus valgus and tardy ulnar nerve palsy requiring nerve transposition. Medial condyle fractures: Residual incongruity is more problematic owing to involvement of the trochlear groove. Little or no soft tissue attachments result in a free articular fragment that may displace. Anterior displacement of the articular fragment into the coronoid or radial fossae may result in a block to flexion. Mechanism of Injury A fall onto an outstretched hand with the elbow in varying degrees of flexion; force is transmitted through the radial head to the capitellum. The capitellotrochlear sulcus divides the capitellar and trochlear articular surfaces. In type I fractures, the lateral trochlear ridge remains with the intact condyle, providing medial to lateral elbow stability. In type I fractures, the lateral trochlear ridge remains intact, therefore preventing dislocation of the radius and ulna. In type I fractures, the lateral trochlear ridge remains intact to provide medial to lateral stability of the radius and ulna. With lateral capsuloligamentous disruption, the radius and ulna may dislocate medially on the humerus.

A survey of 759 households in Bangalore revealed that domestic injuries accounted for 6% of total injuries (Ashok et al how quickly should antibiotics work for sinus infection zithrogen 500 mg cheap. A large-scale community-based survey in Bangalore revealed that domestic injuries accounted for 14% of total injuries antibiotic overdose purchase zithrogen 500 mg visa, with the majority occurring among children and the elderly (Gururaj and Suryanarayana 2004) antimicrobial additive for plastic zithrogen 500 mg low price. In a community-based study in Delhi of 30 antimicrobial bandages zithrogen 500mg generic,554 individuals, the incidence of animal bites was 2. Due to complex medicolegal associations and stigma, suicide has always been concealed in Indian society, severely underreported and misclassified in official reports. From nearly 46,008 suicides in 1974, the number of cases of suicide have nearly tripled during the past three decades. Suicide accounted for 28% of total injury deaths in 2001, with a male to female ratio of 2:1. The State-wise distribution revealed that Pondicherry (50), Kerala (29), Karnataka (24), Tripura (25), Tamil Nadu (18), Maharashtra (15), West Bengal (17), Goa (17), Andhra Pradesh (13) and Sikkim (15) reported higher than the national average rate of 11/100,000. The 23 metropolitan cities of India contributed to 9% of total suicides, revealing that a large majority of suicides occur in rural areas, taluks and districts of India. The cities of Bangalore, Chennai, Delhi and Mumbai recorded nearly half (49%) the number of suicides reported from other cities. Hanging (26%), poisoning (38%), fire/self-immolation (11%) and drowning (8%) were the commonest methods of committing suicide in India. Several researchers in India have examined suicide based on analyses of police data. These studies reveal regional differences, with suicide rates, which vary from 8/100,000 to 95/100,000 population (Gururaj and Isaac 2001a). The majority of studies are based on analyses of police or hospital records with the assumption that all suicides are reported to the police and misclassifications do not exist. The male and female rates were 58 and 148/100,000, indicating a three-fold higher rate among women. These studies clearly indicate that many cases of suicide may not be reported to the police. Several hospital-based reports have revealed the incidence of suicide among the hospital-based population to vary from 5% to 15% of the total emergency and medical admissions (Gururaj et al. The types of violence are broadly classified as self-directed violence (deliberate self-harm or suicide), interpersonal violence (family and intimate partner violence and communal violence) and collective violence (social, political and economic violence). The nature of violent acts could be physical, sexual, psychological and involving deprivation or neglect. In 2000, an estimated 16 lakh people died as a result of violence globally, with an age-adjusted rate of 29/100,000 population. The epidemiology of violence in India has been least understood, since violence is not considered a health problem. The problem, pattern and causes of violence vary significantly across rural/urban areas, between ages and sexes, and in different socioeconomic groups. Similarly, 15 of the 23 metro-politan cities reported higher rates of crime compared with the national average. Rape (11%), dowry deaths (5%) and cruelty by husbands and relatives (35%) were the common patterns. The rate in urban India, especially in cities, was 19/100,000 which is much higher than the national figures.
