Homeopathy is based on an unproved concept of using infinitesimally small amounts of substances which in large amounts can induce symptoms that are being treated generic prandin 2 mg on-line. Since Complementary therapies in neurology 282 the treatment is extremely benign and relatively inexpensive it can be tried by patients who believe that it may help generic prandin 2 mg otc. Combination products The overall efficacy of supplements in clinical trials purchase prandin 0.5mg line, while significantly higher than that of placebo prandin 2 mg on line, is fairly modest purchase prandin 2mg free shipping. This can be due to the fact that some patients respond well, while others do not respond at all. Combining several supplements may increase the chance that one of the ingredients will help, and it is possible that they have a synergistic ® ® effect. MigraHealth and MigreLief are products that combine 300 mg of magnesium, 400 mg of riboflavin and 100 mg of feverfew. TENSION-TYPE HEADACHES 33 Biofeedback is one of the most effective treatments for tension as it is for migraine headaches. Meditation, yoga and other mental exercises can help, but biofeedback is a more direct and a most time-efficient approach aimed at eliminating headaches. Well- trained staff and patient compliance with home exercises are essential for achieving a high success rate. Follow-up studies indicate up to 80–90% improvement 5 years after 4 completion of a biofeedback course. Children can learn to rid themselves of headaches in as few as three to four sessions. Acupuncture has a solid scientific basis confirmed in animal studies, but lacks the proof of large clinical trials. Acupuncture can stop an acute attack of tension-type headache or with a series of treatments relieve a chronic one. Regular aerobic exercise is an excellent way to reduce adverse effects of stress on the body and it usually prevents headaches. CERVICOGENIC HEADACHES Older patients Cervicogenic headaches are more common in older patients and are usually due to osteoarthritic changes in the cervical spine. Pain described as radiating from the neck or occipital area suggests this diagnosis. Pain of cervical spine origin, however, can sometimes be felt in the front of the head. Decreased sensation over the occipital area, often on one side, can accompany occipital neuralgia. Neck muscles are tender, frequently in spasm, and their movement can aggravate the pain. In many patients, immobilization by a soft cervical collar during the night is sufficient to stop the headaches. More often, a combination of a non-steroidal anti-inflammatory drug with a cervical collar and regular isometric neck exercises will provide relief. Local heat application, transcutaneous electrical nerve stimulation (TENS) and acupuncture may be effective. Headache 283 Whiplash injuries Another frequent cause of cervicogenic headaches is a whiplash injury commonly sustained in car accidents. Treatment should include a soft cervical collar, which the patient wears only at night. Wearing the collar during the day for any length of time may cause atrophy of the neck muscles, which may in turn delay the recovery. If pain is severe, the collar can be worn around the clock for the first few days. Local heat, acupuncture and biofeedback are effective as a part of the treatment of acute neck pain and the associated headache. POST-TRAUMATIC HEADACHES In many patients post-traumatic headaches will subside in a few weeks or months without any treatment. Chronic post-traumatic headaches in many patients, however, are notoriously difficult to treat regardless of the presence or absence of litigation. Biofeedback, cognitive therapy, physical therapy with strengthening exercises and acupuncture can be effective in many patients. If headaches have migrainous features the treatments listed above for migraines can produce good results. A supportive and understanding attitude is important in treating this condition, because of the frequent ineffectiveness of treatment and because of the associated neurological and psychiatric symptoms (memory impairment, dizziness, anxiety and depression).

Lung Fields: Note the presence of any shadows from CVP lines purchase prandin 2 mg line, NG tubes, pulmonary artery catheters, etc. The fields should be clear with normal lung markings all the way to the periphery. Descending aorta FIGURE 15–1 Structures seen on a posteroanterior (PA) chest x-ray film. Retrosternal clear space FIGURE 15–2 Structures seen on a lateral chest x-ray film. A reversal of this difference (called cephalization) suggests pulmonary venous hypertension and heart failure. Check the margins carefully; look for pleural thickening, masses, or pneumothorax. If the lungs appear hyperlucent with a relatively small heart and flattening of the diaphragms, COPD is likely. To locate a lesion, do not forget to check a lateral film and remember the “silhouette sign. A radiopac- ity that overlaps the heart but does not obliterate the heart border is posterior and lies in the lower lobes. Coin lesions: Causes are granulomas (50% which are usually calcified), (histoplasmo- sis 25%, TB 20%, coccidioidomycosis 20%, varies with locale); primary carcinoma (25%), hamartoma (<10%), and metastatic disease (<5%). Pay close attention to the retrosternal clear space, costophrenic angles, and the path of the aorta. However, fa- miliarity with OR procedure is crucial to the success of any such experience. Preparing yourself before you get to the OR by knowing the patient thoroughly and having a basic un- derstanding of what is planned will greatly enhance your OR experience. STERILE TECHNIQUE Members of the OR team, which includes the surgeon, assistants, students, and scrub nurse (the one who is responsible for passing the instruments and gowning the OR team), main- tain a sterile field. The circulating nurse acts as a go-between between the sterile and non- sterile areas. Sterile areas include • Front of the gown to the waist 16 • Gloved hands and arms to the shoulder • Draped part of the patient down to the table level • Covered part of the Mayo stand • Back table where additional instruments are kept The sides of the back table are not considered sterile, and anything that falls below the level of the patient table is considered contaminated. ENTERING THE OR From the moment you enter the OR, everything is geared toward maintaining a sterile field. Change into scrub clothing (remem- ber to remove T-shirts and tuck the scrub shirt into the pants). Scrub clothes may occasionally be worn on the wards, provided that they are covered by a clinic coat or some other form of gown, but you 339 Copyright 2002 The McGraw-Hill Companies, Inc. Because of universal precautions, OR staff are now required to use protective eyewear while at the operative field. While wearing glasses, it is helpful to tape the mask to the bridge of your nose to prevent fogging during the surgery. Special masks are also available with self-adhesive strips to help prevent fogging of glasses. Tape the glasses to your forehead if you think they may be loose enough to fall onto the table during the op- eration! Do not wear nail polish, and remove any loose jewelry, watches, and rings before scrubbing. The mask does not need to be worn in the hall of the OR suite (but everything else does) at most hospitals. The mask must be worn in the OR itself, near the scrub sinks, and in the substerile room between ORs. Find the operating room where the patient is located, and assist in transport, if neces- sary. Introduce yourself to the intern or resident and nurse, and try to get an idea of when to begin scrubbing (usually when the first surgeon starts to scrub). If you have a pager, follow the OR procedures and remove the pager if you are going to be scrubbed into the case. THE SURGICAL HAND SCRUB The purpose of a surgical hand scrub is to decrease the bacterial flora of the skin by me- chanically cleansing the arms and hands before the operation. Key points to remember: (1) If contamination occurs during the scrub, it is necessary to start over, and (2) In emer- gency situations exceptions are made to the time allowed for scrubbing (as in obstetrics, when the baby is brought out from the delivery room and the student is still scrubbing!

It is therefore necessary to consider pathological findings with other outcome measures such as impairment generic 2 mg prandin visa. Pathological measures are often primary methods (separate from the symptoms associated with the primary disease) for understanding whether a treatment is © 2005 by CRC Press LLC working generic 1mg prandin amex. For example prandin 2 mg without a prescription, measurement of the size of a brain tumor on MRI scans can form a primary data source with which to compare various chemotherapy treatment regimens order 0.5 mg prandin mastercard. In spine studies prandin 0.5mg, radiographic fusion is often used as a surrogate marker for success of a fusion procedure, even though this marker does not appear to correlate with patient outcomes in most other respects. Clearly, the use of pathological measures may be an important basis to decide on treatment efficacy at a basic level, but these measures likely require supplementation with other types of outcomes to decide whether a treatment on the whole is worthwhile at patient level. Active pathology may result in some type of impairment, but not all impairments are associated with active pathology (e. Impairments can usually be objec- tively specified by an observer such as a physician or surgeon, and are classified in a standard text, the American Medical Association Guide to Impairment. For example, a limitation in shoulder range of motion secondary to a cerebral vascular accident may greatly affect the life of an active patient and be of little importance to a sedentary elderly patient. We will focus our discussion on the disablement model developed by Saad Nagi, a sociolo- gist,12 the International Classification of Impairments, Disabilities and Handicaps (ICIDH-1),13 and its current revision, the International Classification of Functioning, Disability and Health (ICF). It may not constitute a disability for some occupations (manual laborer) but would produce complete disability for others (concert pianist, surgeon). This is a fundamental distinction of critical importance to scholarly discussion and research related to disability phenomena. We will not review the ICIDH-1 classification except to note that in principle this original system was designed as a model for coding and manipulating data on the consequences of health conditions. Part 1 covers functioning and disability including body functions, structures, activities, and participation. Each component consists of various domains and, within each domain, categories that are the units of classification. This view fails to recognize that disablement is more often a dynamic process that can fluctuate in breadth and severity across the life course; it is anything but static or unidirectional. More recent disablement formulations and elaborations of earlier models have explicitly acknowledged that the disablement process is far more dynamic. In these newer concepts, a given disablement process may lead to further downward spiraling consequences. Pope and Tarlov15 use secondary conditions to describe any type of secondary consequence of a primary disabling condition. Commonly reported sec- ondary conditions include pressure sores, contractures, depression, and urinary tract infections, but it should be understood that they can be pathologies, impairments, functional limitations, or additional disabilities. Longitudinal analytic techniques now exist to incorporate secondary conditions into research models and are beginning to be used in disablement epidemiologic investigations. Because patient satisfaction is a multidimensional concept, it is important to start by understanding its multiple definitions. Patient satisfaction is a complex concept that may incorporate sociode- mographic, cognitive, and affective components. Although many theories for patient satisfaction have been proposed, few have been extensively tested and validated in different health care settings. Moreover, few studies have been conducted to explain associations between patient satisfaction and patient characteristics or subsequent patient behaviors. Although theories of patient satisfaction are difficult to categorize in an organized and easily comprehensible fashion, one may group these theories into intrapatient comparisons (disconfirmation theory) and differences between individual patients and health care providers (attribution theory) or other patients (equity theory). Intrapatient comparison theories explain the satisfaction phenomenon by a match between patient expectations and perceptions of medical care. Differences between what is expected and what is perceived to occur will contribute to patient satisfaction or dissatisfaction. This theory is the dominant model of nonmedical customer sat- isfaction in which consumers compare their perceptions of a product or service against prior expectations. Equity theories are based on the premise that patient satisfaction relates to whether patients believe they have been fairly treated. Equity occurs when patients compare their balances of inputs (time and money) and outputs (medical care and its results) with those of other patients. Patient satisfaction occurs when people perceive they are treated fairly; it may increase when patients perceive their outcomes as more favorable than those of other patients with the same conditions. A related concept is gap analysis in which identification of differences between provider and patient perceptions of services occurs. Addressing potential gaps arising because providers focus primarily on delivery of medical care and patients focus on services used may increase patient satis- faction.

Use one hand to hold the catheter near the skin and to control the insertion while using the other hand to apply pressure to the end of the catheter order 2mg prandin overnight delivery. After entering the peritoneal cavity order prandin 1 mg, remove the tro- car and direct the catheter inferiorly into the pelvis purchase prandin 2mg free shipping. Gently agitate the abdomen to distribute the fluid and after 5 min prandin 1mg discount, drain off as much fluid as possible into a bag on the floor generic 2mg prandin with visa. If the catheter is inserted for pancreatitis or peritoneal dialysis, suture it in place. A false-positive DPL can be caused by a pelvic fracture or bleeding induced by the procedure (eg, laceration of an omental vessel). Complications Infection/peritonitis or superficial wound infection, bleeding, perforated viscus (bladder, bowel) PERITONEAL (ABDOMINAL) PARACENTESIS Indications • To determine the cause of ascites • To determine if intraabdominal bleeding is present or if a viscus has ruptured (Diag- nostic peritoneal lavage is considered a more accurate test. Ascites is indicated by abdominal distention, shifting dullness, and a palpable fluid wave. Have the patient empty the bladder, or place a Foley catheter if voiding is impossible or if signif- icant mental status changes are present. With the catheter mounted on the syringe, go through the anesthetized area carefully at an oblique angle while gently aspirating. When you get free return of fluid, leave the catheter in place, remove the needle, and begin to aspirate. Quickly remove the needle, apply a sterile 4 × 4 gauze square, and apply pressure with tape. Depending on the clinical picture of the patient, send samples for total protein, specific gravity, LDH, amylase, cytology, culture, stains, or CBC. Complications Peritonitis, perforated viscus, hemorrhage, precipitation of hepatic coma if patient has se- vere liver disease, oliguria, hypotension Diagnosis of Ascitic Fluid A complete listing is found in Chapter 3, page 43. Exudative ascites is found with tumors, peritonitis (TB, perfo- rated viscus), hypoalbuminemia. Pleural fluid glucose is much lower than serum glucose in effusions due to rheumatoid arthritis (0–16 mg/100 mL); low 40 mg/100 mL in empyema. Abbreviations: LDH = lactate dehydrogenase; WBC = white blood cells; RBC = red blood cells; PMNs = polymorphonuclear neutrophils; TB = tuberculosis. Background Pulsus paradoxus is an exaggeration of the normal inspiratory drop in arterial pressure. The result is increased right atrial and right ventricu- lar filling with an increase in right ventricular output. Because the pulmonary vascular bed also distends, these changes lead to a delay in left ventricular filling and subsequently a de- creased left ventricular output. In the case of cardiac compression (eg, acute asthma or pericardial tamponade), the right side of the heart fills more with inspiration and decreases the left ventricular volume to even greater degree as a result of compression of the pericardial sac. A simple, qualitative method involves palpating the radial pulse, which “disappears” on normal inspiration. A more precise quantitative method requiring that the patient take a breath, let it out, and hold it. Once the patient is breathing normally, drop the pres- sure in the cuff slowly until you hear the pulse during inspiration. Differential diagnosis includes pericardial effusion, cardiac tamponade, pericarditis, COPD, bronchial asthma, restrictive cardiomyopathies, hemorrhagic shock SIGMOIDOSCOPY (RIGID) Indications • Diagnosis and treatment of lower gastrointestinal problems • Part of the standard work-up of blood in the stool Materials • Examination gloves, lubricant, tissues • Occult blood stool test kit (Hemoccult paper and developer) • Sigmoidoscope with obturator and light source 13 • Insufflation bag • Long (rectal) swabs and suction catheter • Proctologic examination table (helpful but not essential) Procedure 1. These include rigid sigmoidoscopy (endoscopic examination of the last 25 cm of the GI tract), flexible sig- moidoscopy (examination up to 40 cm from the end of the GI tract), proctoscopy (roughly synonymous to sigmoidoscopy, but technically means examination of the last 12 cm), and anoscopy (examination of the anus and most distal rectum). Sigmoidoscopy can be performed with the patient in bed lying on side in the knee–chest position, but the best results are obtained with the patient in the “jackknife” position on the procto table. Do not position the patient until all materials are at hand and you are ready to start. Do a careful rectal exam with a gloved finger and plenty of lubricant, and check for fecal occult blood (Hemoccult test) on the stool recovered on the glove. Lubricate the sigmoidoscope well with water-soluble jelly, and insert it with the obtura- tor in place.
