Lower extremities evaluation

Periodically evaluate patients who receive prophylaxis during the course of treatment for signs and symptoms of VTE, such as swelling, pain, warmth, and redness of lower extremities, and for DVT, as well as chest pain, shortness of breath, palpitations, and hemoptysis. 

EF is a 45-year-old woman who presents to the dermatologist for evaluation of facial acne. She has a history of a 25 lb (11.36 kg) weight gain, irregular menses, and frequent vaginal yeast infections over the past 2 years. She complains of increased facial hair growth and lower extremity muscle weakness. Physical examination reveals facial acne, facial hirsutism, truncal obesity, thin skin, and purple abdominal striae. Her past medical history is significant for hypertension, type 2 diabetes mellitus, hyperlipidemia, and rheumatoid arthritis.

One of the stacks was operated at a fixed current over more than 400 hours and its durability was evaluated. The three cells did not lead to the same degradation rates. The lowest degradation rate was obtained on the central cell (10%/1000 h) whereas it was much higher on the upper and lower extreme cells (35 and 49%/l 000 h respectively). Such degradation values are of the same order of magnitude as some of those reported in literature. 

Case Conclusion CC s oncologist decides to stop the interferon therapy and initiate a trial of imatinib mesylate. She tolerated the imatinib well, with minimal complaints of lower extremity edema for which she was prescribed furosemide. Six weeks after starting imatinib, CC s peripheral blood smear appeared normal (hematologic response) and cytogenetic evaluation of her bone marrow revealed disappearance of the Philadelphia chromosome. 

A physical examination of the patient should include a check for hypogonadism (i.e., signs of gynecomastia, small testicles, and decreased body hair). The penis should also be evaluated for diseases associated with penile curvature (e.g., Peyronie s disease), which are also associated with erectile dysfunction. Femoral and lower extremity pulses should be assessed to provide an indication of vascular supply to the genitals. Anal sphincter tone and other genital reflexes should be checked to provide an indication of the integrity of the nerve supply to the penis. 

As outlined in Table 13.1, three Phase I trials for intramuscular and intra-arterial administration of naked plasmid VEGEigs in human lower-extremity ischemia and BuergeTs disease have been completed, having achieved their end-points within one year. Three Phase II clinical trials are currently recruiting patients to investigate the role of intramuscular VEGE plasmid delivery in lower-extremity ischemia. A Phase I trial for intra-arterial administration of recombinant PGE-2 has been completed (Table 13.1), and the Phase II TRAFFIC trial further evaluating the effect...

The primary study end-point was incidence of DVT and other thromboembolic events assessed clinically and by both locally and centrally assessed ultrasonography. The duplex-ultrasounds of the lower extremities were used to confirm or exclude the occurrence of DVT. These procedures were performed and interpreted by qualified specialists within the same hospi-tal/institution on a real-time basis for the timely and appropriate chnical care of the patient Furthermore, duplex ultrasound studies were videotaped for a subsequent standardized bhnded interpretation by a quahfied, independent laboratory that provided an unbiased evaluation of the incidence of DVT. ThromboemboHc events other than DVT that occurred during the study period were assessed, and the investigator estabhshed the clinical relationship of the event to treatment with rhAT. Secondary end-points were safety, adverse events and immunogenicity. 

All patients with chronic pelvic pain should have the benefit of clinical evaluation and shared care by a physician with expertise in chronic pelvic pain. A laparoscopy and pelvic ultrasound should be performed prior to radiologic interventions. Their role is to exclude other diagnoses, not to make the diagnosis of pelvic congestion. If the clinical presentation is recurrent lower extremity varicose veins or...

Lower-extremity CTA can be performed with all currently available MDCT scanners. No special hardware is required. Because of the slightly thicker sections (2.5-3 mm) usually obtained with four-channel MDCT (4 X 2.5 mm), evaluation of crural and pedal arteries is slightly limited, notably if calcifications are present. The technical limitations of four-channel MDCT are only clinically problematic in a small subset of patients, such as individuals with critical limb ischemia who have no or mild inflow and femoropopliteal disease, and who have diseased and calcified infrapopliteal vessels. In the majority of patients—notably those with intermittent claudication where interventions are limited to aboveknee arteries—even four-channel MDCT can provide all the therapeutically relevant information (Heijen-brok-Kal et al. 2007 Rubin et al. 2001 Ofer et al. 2003 Martin et al. 2003 Ota et al. 2004 Catalano et al. 2004).

Claudication is a clinical, easy to make diagnosis. Claudication of the upper extremities, although much less frequent than that of the lower extremities, is also a clinical diagnosis. The extremities should be examined carefully. Examination of the peripheral arterial system should include an evaluation of the volume and character of the arterial pulses of the carotids and of the arteries of the upper extremities the subclavian, the brachial, the radial, and the ulnar. Physical examination should definitely encompass the abdominal aorta for abnormal pulsations, ectasias and/or bruits, and the arteries of the lower extremities femoral, popliteal, dorsalis pedis, and posterior tibialis. The pulse volume can be graded on a scale of 0 to 4. In addition to palpation, physical examination of the peripheral arterial system should include auscultation over the carotids, auscultation over the subclavian arteries above, and below the mid-clavicular area. A bruit over the subclavian artery and disappearance of the radial pulse with compression of the subclavian artery is evidence for subclavian syndrome. On occasion, a bruit may be heard by auscultation deep in the axilla. The bruit, a composite of low frequency sounds, is better appreciated when the examiner is using the bell of the stethoscope. 

The evaluation of a patient with lower extremity arterial occlusive disease starts with a detailed history and a complete physical examination (1). A thorough pulse exam of both upper and lower extremities is of outmost importance. Absence of palpable pulses at any level indicates hemodynamically significant lesion(s) to the main artery proximal to that level. Thus, absence of palpable femoral pulses is suggestive of severe stenosis or occlusion of the ipsilateral iliac artery (2).

Clearly, diabetics who have peripheral arterial disease have higher mortality rates than those who do not have arterial disease. A recent study by Vogt et al. (15) evaluated the relationship between peripheral arterial disease and mortality in a population of close to 2000 individuals over a 13-year period. All patients 50 years of age and older with no history of lower extremity surgery were evaluated for the presence of peripheral arterial disease. Analysis of the data stratified by populations and comorbid conditions showed that a low ankle-brachial index is an independent predictor of all causes of mortality in both men and women with peripheral arterial disease. This increase is a relative risk and is unchanged after exclusions of all patients with a clinical history of cardiovascular disease or diabetes. Thus, a low ankle-brachial index is an important measurement to obtain to assess the risk of mortality among those who smoke and have either angina or diabetes. 

The purpose of their review was to evaluate the prevalence of diabetes and other common predisposing factors in amputation of the lower extremities. The combination of diabetes and hypertension was present in 40 of these patients (36%). The investigators found when either diabetes or hypertension was present in a patient, hypertension not diabetes was the more common dominant underlying medical condition in patients with amputations (32 hypertensionalone patients vs 10 diabetes-alone patients). This study supports the concept that hypertension plays an important role in the development of peripheral vascular disease. 

The surgical treatment of lower-extremity ischemia must be based on the severity of the patient s symptoms and the overall medical condition of the individual. Atherosclerosis is a systemic process, and these patients are predisposed to stroke, myocardial infarction, and hypertension caused by the involvement of other arterial segments. The extent of such involvement requires full evaluation prior to lower extremity surgery, and some patients may require carotid endarterectomy or coronary artery bypass grafting or stenting before infrainguinal reconstruction is undertaken. 

With the patient in the sitting position, her lower extremity muscle strength, cutaneous sensation, and deep tendon reflexes were evaluated. There was a slight diminution of the ieft Achilles reflex present The seated straight leg-raising test was positive. 

The normal walking cycle in the lower extremities is accompanied by regular motions of the shoulders, arms, and head. Their actions are part of any clinical evaluation. When the pelvis on the swing side moves forward, the shoulder on that side drops back. Therefore, the opposite arms and iegs swing in tandem. 

Proper sacral and pelvic joint motion should be achieved in all gait, posture, and spinal motion problems. Because the sacrum Is closely associated with cranial motion, the sacrum must be evaluated as pan of the cranial motion evaluation. Lower extremity dysfunction often results from or may cause pelvic dysfunctions. 

The bursitis has as its cause trauma to the area, acute or chronic, as well as any dysfunction affecting the ischium or the structurai integrity of the knee joint. The patient reports pain at the medial aspect of the knee, but careful palpation will elicit point tenderness below the knee joint that is very specific and localized in its nature. The pain will be made worse with contraction of the semitendinous, sartorius, and gracilis muscles. An evaluation for somatic dysfunctions of the pelvis, sacrum, and lumbar region, as well as the postural balance of the lower extremity, must be performed. Treatment can be a local injection of a steroid, a prescription for a NS AID, ice, exercises, and osteopathic manipulative treatment (OMT) of all somatic dysfunctions, including knee, hip. and pelvic region.
