Extremities lower

If it is not dissolved or trapped, an embolism moving from the lower extremities can be life-threatening. People afflicted with phlebitis are particularly susceptible to this problem. A shape-memory trap has been devised that, when deployed in the vena cava, is like a multileaved mesh that traps a traveling embolism, retaining it until medication can dissolve it. Introduced in a folded form by a catheter, the mesh is prevented from deploying by subjecting it to a flow of cold saline water. Once in place, it is released from the catheter and, warmed by body heat, opens into its final shape (11). 

Diethylcarbama2iae has limited antimicrofilarial activity against Onchocerca volvulus. Adults of W. bancrofti the filarial worm causiag elephantiasis, coil in the lymph system. Here females can attain a length of 10 cm. Over the years, tissue reactions result in obstmction to lymph return. Lymph nodes, lymph vessels, and the spleen become enlarged. The condition of elephantiasis is a late and unusual complication of filariasis, where the lower extremities of the body become edematous, enlarge, and over a period of time harden with a rough nodular skin. 

In general, arterial thrombi are platelet-rich ( white clots ) and form at ruptured atherosclerotic plaques, leading to intraluminal occlusion of arteries that can result in end-organ injury (e.g., myocardial infarction, stroke). In contrast, venous thrombi consist mainly of fibrin and red blood cells ( red clots ), and usually form in low-flow veins of the limbs, producing deep vein thrombosis (DVT) the major threat to life results when lower extremity (and, occasionally, upper extremity) venous thrombi embolize via the right heart chambers into the pulmonary arteries, i.e., pulmonary embolism (PE). 

Spinal anesthesia is a type of regional anesthesia that involves the injection of a local anesthetic drug into the subarachnoid space of die spinal cord, usually at the level of the second lumbar vertebra There is a loss of feeling (anesdiesia) and movement in the lower extremities, lower abdomen, and perineum. 

If the patient has a DVT, it usually occurs in a lower extremity. The nurse examines the extremity for color and skin temperature The nurse also checks for a pedal pulse, noting the rate and strength of the pulse. It is important to record any difference between the affected extremity and the unaffected extremity. The nurse notes areas of redness or tenderness and asks the patient to describe current symptoms. The affected extremity may appear edematous and exhibit a positive Homans sign (pain in the calf when the foot is dorsiflexed). A positive Homans sign is suggestive of DVT. 

The nurse weighs the patient with inoperable breast carcinoma daily or as ordered by the primary health care provider. If the patient is on complete bed rest, the nurse may take weights every 3 to 4 days (or as ordered) using a bed scale The nurse notifies the primary health care provider if there is a significant (> 5 lb) increase or decrease in the weight. The nurse checks the lower extremities daily for signs of edema. 

MANAGING THROMOOEMOOLIC EFFECTS. The nurse monitors the patient for signs of thromboembolic effects, such as pain, swelling, tenderness in die extremities, headache, chest pain, and blurred vision. These adverse effects are reported to die primary health care provider. Patients with previous venous insufficiency, who are on bed rest for other medical reasons, or who smoke are at increased risk for tiiromboembolic effects. The nurse encourages the patient to elevate the lower extremities when sitting, if possible, and to exercise the lower extremities by walking. 

Epidermal nerve fiber analysis by immunocytochemical techniques using the panaxonal marker protein gene product 9.5 (PGP 9.5) allows the study of epidermal innervation by small fiber C and A5 nerve fibers (McCarthy et al. 1995 Holland et al. 1997). Studies of skin biopsies of HIV infected patients with DSP or ATN showed reduction in the number of epidermal fibers in distal areas of the lower extremities with an inverse correlation between neuropathic pain intensity and epidermal nerve fiber density (Polydefkis et al. 2002) (Fig. 4.3). There were also fewer epidermal fibers in HIV seropositive patients without clinical evidence of neuropathy, suggesting that HIV infection may be associated with the loss of cutaneous innervation even before the onset of sensory symptomatology (McCarthy et al. 1995).

The risk of venous thromboembolism (VTE) is related to several easily identifiable factors including age, prior history of VTE, major surgery (particularly orthopedic procedures of the lower extremities), trauma, malignancy, pregnancy, estrogen use, and hypercoagulable states. These risks are additive. 

The ACCP Conference on Antithrombotic Therapy recommended against the use of aspirin as the primary method of VTE prophylaxis.2 Antiplatelet drugs clearly reduce the risk of coronary artery and cerebrovascular events in patients with arterial disease, but aspirin produces a very modest reduction in VTE following orthopedic surgeries of the lower extremities. The relative contribution of venous stasis in the pathogenesis of venous thrombosis compared with that of platelets in arterial thrombosis likely explains the reason for this difference. 

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. 

Instruct the patient regarding nonpharmacologic strategies including elevation of the affected extremity and anti-embolic exercises such as flexion/extension of the ankle (for lower extremity VTE) or hand squeezing/relaxation (for upper extremity VTE).

Epidural analgesia is frequently used for lower extremity procedures and pain (e.g., knee surgery, labor pain, and some abdominal procedures). Intermittent bolus or continuous infusion of preservative-free opioids (morphine, hydromorphone, or fentanyl) and local anesthetics (bupivacaine) may be used for epidural analgesia. Opiates given by this route may cause pruritus that is relieved by naloxone. Adverse effects including respiratory depression, hypotension, and urinary retention may occur. When epidural routes are used in narcotic-dependent patients, systemic analgesics must also be used to prevent withdrawal since the opioid is not absorbed and remains in the epidural space. Doses of opioids used in epidural analgesia are 10 times less than intravenous doses, and intrathecal doses are 10 times less than epidural doses (i.e., 10 mg of IV morphine is equivalent to 1 mg epidural morphine and 0.1 mg of intrathecally administered morphine).45... 

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.

Foot ulcers and related infections are among the most common, severe, and costly complications of diabetes mellitus (DM). Fifteen percent of all patients with DM develop at least one foot ulcer, resulting in direct health care expenditures of approximately 9 billion annually in the United States.26,27 Diabetic foot ulcers and wounds are highly susceptible to infection. Related skin, soft tissue, and bone infections account for 25% of all diabetes-related hospitalizations.28 More than half of all nontraumatic lower extremity amputations (LEAs) performed each year in Western nations are linked to diabetic foot infection 80,000 LEAs are performed annually in the United States alone.29,30...
