He reports four episodes of nonbilious purchase zebeta master card, nonbloody vomiting since the pain started; no diarrhea; no blood per rectum; denies fever or chills; denies any urinary symptoms or fank pain; denies similar episodes of pain in the past order zebeta 10mg mastercard. Social: recently divorced; smoker (30 packs/year) discount 10 mg zebeta fast delivery, drinks alcohol when he parties with friends on weekends; denies any drug abuse g. Pharynx: normal dentition, no lesions, no swelling Case 74: Abdominal Pain 319 Figure 74. Abdomen: bowel sounds hypoactive, mildly distended, obese, tenderness in epigastric area with guarding; no rebound; no rigidity l. This is a case of pancreatitis in a patient with a history of heavy alcohol consump- tion for years and recent binge drinking. As in our patient, the pain is typically sharp and constant in nature and radiat- ing to back associated with nausea and vomiting. If the patient does not get pain medications, he should start getting more upset and agitated. If the patient does not get at least 2 L of fuids, the blood pressure will decline and the patient will become more agitated. The degree of elevation in amylase and lipase does not correlate with severity of the disease. Ranson’s criteria is just a tool for prognosis and does not change the emergency management of these patients. These patients require aggressive fuid resuscitation due to sequestration of large volumes of fuid in the retroperitoneum. Bluish discoloration in the left fank (Turner’s sign) and around the umbilicus (Cullen’s sign) are rarely seen, but indicate hemorrhagic pancreatitis. It is most useful to rule out complications such as pancreatic phlegmon or abscess. Patients with chronic pancreatitis do not usually have elevation of pancreatic enzymes due to chronic damage to the organ. Patient agitated and ill-appearing; in no acute respiratory distress; appears very uncomfortable due to pain, changing her position constantly in stretcher to fnd a comfortable position. Patient describes a severe pain severe 10/10 pain which is intermittent, diffuse but mostly in lower abdomen associated with nausea and diarrhea. General: alert, oriented × 3, appears agitated and in severe distress due to abdominal pain b. Bowel sounds hypoactive mild distention, mild tenderness diffusely, more prominently in lower abdomen without rebound or guarding l. Female: no blood or discharge, cervical os closed, no cervical motion ten- derness, no adnexal tenderness n. Ischemic bowel, embolism to superior mesenteric artery 326 Case 75: Abdominal Pain Case 76: shortness of Breath N. This is a case of bowel ischemia secondary to an embolic clot from atrial fbrilla- tion. The patient’s symptoms are due to a lack of blood supply to the intestines secondary to a blood clot which has occluded one of the major blood vessels to the intestines. Atrial futter, an irregular heart rhythm, has predisposed her to developing blood clots. Both services initially do not want to take the patient for defnitive treatment and the candidate will need to be persistent. Mesenteric ischemia/infarction is typically seen in the elderly population with cardiovascular disease such as atrial fbrillation, congestive heart failure, and coronary artery disease. The most common cause of ischemic bowel is mesenteric artery occlusion as a result of embolus from the heart in atrial fbrillation (65%-75% of cases). Patient alert and awake with anxious affect; moderate respiratory distress; using accessory muscle to breathe. Airway: able to speak in one-word sentences only, secondary to shortness of breath b. Breathing: moderate respiratory distress, cyanotic around lips and fngertips; diffuse wheezing c. The patient denies fever, chills, headache, nausea, vomiting, diarrhea, chest pain. Social: heavy smoker (30 pack per year) recently decreased the number of cigarettes to 6 to 7 per day; denies alcohol or drug abuse; lives at home alone g. Lungs: tachypneic, using accessory muscles to breath, diffuse wheezing bilater- ally, scattered rhonchi j. Unless aggressive management is instituted with albuterol, Atrovent, steroids, and magnesium, the patient’s shortness of breath will worsen. Anticholinergic agents such as ipratropium bromide work on larger central air-Anticholinergic agents such as ipratropium bromide work on larger central air- way as opposed to b-agonists agents such as albuterol, that work on the small peripheral airways. Ipratropium bromide has a synergistic effect when used with albuterol, although has slower onset of action. Steroid use is less compelling compared to asthma exacerbation, but still should be given in all acute exacerbation. The risk of oxygen-induced apnea if the patient is tachypneic is less compared to when the patient is bradypneic. Regardless if the patient is in respiratory dis- tress, oxygen should be given in high concentrations. Patient appears unkempt attire, covered in urine; appears confused, but more awake; uncooperative with staff; agitated. General: agitated, confused, abusive to staff; uncooperative with the history and examination Figure 77. Pharynx: normal dentition, no lesions, no swelling, small laceration on tongue with minimal bleeding h. Neuro: uncooperative with examination; patient is confused and awake; appears to be oriented to person; unsure of date or location; affect agitated; no focal def- cits noted p. Seizure secondary to the cessation of alcohol in a chronic user can be a life-threatening condition if left untreated. The patient is confused and agitated because of a recent unwitnessed seizure in the feld and will continue to become more agitated and abusive to staff until proper medication or restraints are applied. If haloperidol is given, the patient will initially calm down, but will sieze a few minutes later. The patient will proceed to have a generalized tonic-clonic seizure that will only respond to lorazepam, 8 mg, or equivalent. The patient should be admitted to a monitored bed and continued on benzodiazepines for withdrawal. Any patient with seizure activity should be assessed for possible alcohol-related seizures. Alcoholic patients are prone to hypoglycemia due to decreased reservoir of gly- cogen secondary to chronic liver damage; blood glucose should be assessed for all alcoholics with mental status changes. Administration of glucose should not be given before thiamine in suspected alcoholics since it can precipitate Wernicke’s encephalopathy or Korsakoff’s syndrome with potentially irreversible brain damage. Always assess alcoholics fully for trauma, infection, and metabolic abnormalities.
To prevent permanent nerve damage generic zebeta 10mg with mastercard, however generic zebeta 5 mg without prescription, surgery should not be delayed beyond three years after ﬁrst onset of symptoms buy zebeta 10 mg mastercard. Open carpal tunnel release surgery is one of the most commonly performed outpatient surgeries and is less expensive than the newer endoscopic procedures. A detailed review reported no difference in long-term results between the procedures, but pain is reduced the ﬁrst two weeks following the endoscopic surgery compared with open procedures. Specialized splints have not been proven more effective than a good-quality, well-fitted over-the-counter splint. Alternating hot and cold water treatment (contrast hydrotherapy) provides a simple, efﬁcient way to increase circulation to the area and reduce swelling. Immersion of the hand past the wrist in hot water for three minutes, followed by immersion in cold water for 30 seconds, repeated three to ﬁve times, will increase local circulation, thereby increasing local inﬂow of nutrients, increasing elimination of waste products, and decreasing pain. If B6 does not produce results within a few weeks, P5P should be tried at 10 mg per day. Celadrin Celadrin is a proprietary mixture of cetylated fatty acids that has been shown to affect several key factors that contribute to inﬂammation. Studies have assessed both the oral and the topical use of Celadrin in the treatment of osteoarthritis (see the chapter “Osteoarthritis”). Acupuncture A randomized controlled study comparing an oral steroid (prednisolone 20 mg for two weeks, then 10 mg for two weeks) vs. Diet Follow the general recommendations given in the chapter “A Health-Promoting Diet. Cataracts • Clouding or opacity in the crystalline lens of the eye • Gradual loss of vision Cataracts are white, opaque blemishes on the normally transparent lens of the eye. They occur as a result of damage to the protein structure of the lens, similar to the damage that occurs to the protein of eggs when they are boiled or fried. Cataracts are the leading cause of impaired vision and blindness in the United States. Approximately 6 million Americans have some degree of vision- impairing cataract, and among Medicare recipients, cataract surgery is the most common major surgical procedure, with nearly 1 million procedures each year. Cataracts can be classiﬁed by location and appearance of the lens opacities, by cause or signiﬁcant contributing factor, and by age of onset. Many factors may cause or contribute to the progression of lens opacity, including ocular disease, injury, or surgery; systemic diseases (e. Aging-related cataracts (senile cataracts) are discussed in this chapter, and diabetic and galactose-induced cataracts (sugar cataracts) are discussed in the chapter “Diabetes. The majority of the geriatric population displays some degree of cataract formation. Even with normal aging there is a progressive increase in size, weight, and density of the lens. Causes In cataract formation, the normal protective mechanisms are unable to prevent free radical damage to the cells of the lens. Lutein Lutein, a yellow-orange carotene that offers signiﬁcant protection against macular degeneration, also helps protect against cataract formation. In 1992 a study showed that consumption of spinach (high in lutein) was inversely related to the risk of cataracts severe enough to require extraction. Vitamin C A high dietary intake of vitamin C from either dietary sources or supplements has been shown to protect against cataract formation. Several clinical studies have demonstrated that vitamin C supplementation can halt cataract progression and, in some cases, signiﬁcantly improve vision. For example, in one study conducted in 1939, 450 patients with cataracts were started on a nutritional program that included 1 g per day of vitamin C, which resulted in a signiﬁcant reduction in cataract development. It appears that the dosage of vitamin C necessary to increase the vitamin C content of the lens is 1,000 mg. In order for these concentrations to be maintained in these tissues, the body has to generate enormous amounts of energy to pull vitamin C out of blood against this tremendous gradient. Keeping blood vitamin C concentrations elevated helps the body concentrate vitamin C into active tissue by reducing the gradient. That is probably why such high dosages are required to raise the vitamin C content of the lens. In another study, 450 patients with incipient cataracts were started on a nutritional program that included 1,000 mg per day of vitamin C, which led to a signiﬁcant reduction in cataract development. This study may have failed to show benefit because it was below the threshold of 1,000 mg per day of vitamin C. Selenium and Vitamin E Selenium and vitamin E are antioxidants known to function synergistically. Maintaining proper selenium levels appears to be especially important because the lens antioxidant enzyme glutathione peroxidase requires selenium. Low selenium levels greatly promotes cataract formation; early studies have shown that selenium content in the human lens with a cataract is only 15% of normal levels. Selenium levels in the serum and aqueous humor were found to be signiﬁcantly lower in the patients with cataracts (serum, 0. However, selenium levels in the lens itself did not signiﬁcantly differ between the patients with cataracts and the controls. The most important ﬁnding of the study was the decreased level of selenium in the aqueous humor in patients with cataracts. Excessive hydrogen peroxide levels, up to 25 times normal, are found in the aqueous humor in patients with cataracts and are a key underlying factor in cataract formation. Because selenium-dependent glutathione peroxidase is responsible for the breakdown of hydrogen peroxide, it is quite obvious why low selenium levels appear to be a major factor in the development of cataracts. As previously described, vitamin E supplementation alone does not slow the progression of cataract formation. Levels of these necessary cofactors are greatly reduced in lenses with cataracts; copper and zinc levels are reduced by more than 90%, and manganese by 50%. Studies of human senile cataracts have demonstrated decreased levels of tetrahydrobiopterin and pteridine-synthesizing enzymes. However, no more than 10 mg per day of riboﬂavin should be taken by people with cataracts, because it is a photosensitizing substance—that is, riboﬂavin reacts with the light to form superoxide free radicals. In animal studies, riboﬂavin supplementation and light have been used experimentally to induce cataracts. The evidence appears to suggest that excess riboflavin does more harm than good in patients with cataracts. Zinc, Vitamin A, and Beta-Carotene Zinc, vitamin A, and beta-carotene are known antioxidant nutrients vital to the health of the eye. In particular, beta-carotene may act as a ﬁlter, protecting against light-induced damage to the ﬁber portion of the lens. In one human study, bilberry extract plus vitamin E stopped progression of cataract formation in 97% of 50 patients with senile cortical cataracts. Heavy Metals A number of heavy metals have been shown to have higher concentrations in both the aging lens and those with cataracts. Because cadmium displaces zinc from binding as a coenzyme in enzymes, it may contribute to deactivation of free radical quenching and other protective/repair mechanisms.
Exercise appears to be effective in lowering intraocular pressure in sedentary subjects engaging in moderate to heavy exercise but is somewhat less effective in physically ﬁt subjects purchase generic zebeta from india. Although exercise may not be effective in lowering intraocular pressure in everyone cheap generic zebeta uk, it can lead to signiﬁcant improvements in many generic 5mg zebeta amex. One study found a postexercise intraocular pressure drop of at least 2 mm Hg in 34% of subjects; however, 57% had no change, while 9% had an elevation in pressure. In particular, engage in regular physical exercise and follow the guidelines in the chapter “A Health-Promoting Diet. In gout, uric acid crystals (monosodium urate) are deposited in joints, tendons, kidneys, and other tissues, where they cause considerable inﬂammation and damage. The ﬁrst attack of gout is characterized by intense pain, usually involving only one joint. The ﬁrst joint of the big toe is affected in nearly half of ﬁrst attacks and is at some time involved in more than 90% of individuals with gout. The ﬁrst attacks usually occur at night and are usually preceded by a speciﬁc event, such as dietary excess, alcohol ingestion, trauma, certain drugs (mainly chemotherapy drugs, certain diuretics, and high doses of niacin), or surgery. The classic description of gout was written by an English physician, Thomas Sydenham, who suffered from it in 1683. This is Sydenham’s classic description: The victim goes to bed and sleeps in good health. About two o’clock in the morning he is awakened by a severe pain in the great toe; more rarely in the heel, ankle, or instep. The pain is like that of a dislocation, and yet parts feel as if cold water were poured over them. After a time this comes to a height, accommodating itself to the bones and ligaments of the tarsus and metatarsus. Now it is a violent stretching and tearing of the ligaments, now it is a gnawing pain, and now a pressure and tightening. So exquisite and lively meanwhile is the feeling of the part affected, that it cannot bear the weight of bedclothes nor the jar of a person walking in the room. The night is passed in torture, sleeplessness, turning the part affected, and perpetual change of posture; the tossing about of the body being as incessant as the pain of the tortured joint, and being worse as the fit comes on. Hence the vain effort by change of posture, both in the body and the limb affected, to obtain an abatement of pain. Subsequent attacks are common, with the majority of gout patients having another attack within one year. Chronic gout is extremely rare these days, owing to the advent of dietary therapy and drugs that lower uric acid levels. Some degree of kidney dysfunction occurs in almost 90% of subjects with gout as a result of uric acid deposits, and there is a higher risk of kidney stones. Primary gout accounts for about 90% of all cases, while secondary gout accounts for only 10%. There are, however, several genetic defects in which the exact cause of the elevated uric acid is known. The increased serum uric acid level observed in primary gout can be divided into three categories: 1. Overproduction and underexcretion of uric acid, found in a small minority of gout patients Although the exact metabolic defect is not known in the majority of cases, gout is one of the most controllable metabolic diseases. Secondary gout refers to those cases in which the elevated uric acid level is a result of some other disorder, such as excessive breakdown of cells or some form of kidney disease. Diuretic therapy for high blood pressure and low-dose aspirin therapy are also important causes of secondary gout, since they cause decreased uric acid excretion. Causes of Gout • Increased purine intake • Increased production of purines (primary causes): Idiopathic (unknown causes) Due to specific enzyme defects • Increased production of purines (secondary to another factor) • Increased turnover of purines due to: Cancer Chronic hemolytic anemia Chemotherapy drugs Psoriasis • Increased synthesis of purines • Increased breakdown of purines due to: High fructose intake Exercise • Impaired kidney function: Decreased kidney clearance of uric acid (primary) Intrinsic kidney disease Decreased kidney clearance of uric acid (secondary) Functional impairment of kidney function – Drug-induced (e. The dietary contribution to the level of uric acid in the blood is usually only 10 to 20% of the total, but purines and uric acid obtained through the diet can increase crystal formation in tissues nonetheless. Although higher concentrations do not necessarily result in the deposit of uric acid crystals in tissues (some unknown factor in serum appears to inhibit crystal precipitation), the chance of an acute attack of gout is greater than 90% when the level is above 9 mg/100 ml. Lower body temperatures decrease the saturation point of uric acid, and this may explain why uric acid deposits tend to form in areas such as the top of the ear, where the temperature is lower than the average body temperature. Therapeutic Considerations The current standard medical treatment of acute gout is administration of colchicine, an anti- inﬂammatory drug originally isolated from the plant Colchicum autumnale (autumn crocus, meadow saffron). Colchicine has no effect on uric acid levels; rather, it stops the inﬂammatory process by inhibiting neutrophil migration into areas of inflammation. More than 75% of patients with gout show major improvement in symptoms within the ﬁrst 12 hours after receiving colchicine. However, up to 80% of patients are unable to tolerate an optimal dose because of gastrointestinal side effects. Colchicine may also cause bone marrow suppression, hair loss, liver damage, depression, seizures, respiratory depression, and even death. Once the acute episode has resolved, a number of measures are taken to reduce the likelihood of recurrence: • Drugs such as allopurinol or febuxostat to keep uric acid levels within a normal range • Controlled weight loss in obese individuals • Avoidance of known precipitating factors such as heavy alcohol consumption or a diet rich in purines or refined carbohydrates • Low doses of colchicine to prevent further acute attacks Several dietary factors are known to lead to the development of gout or trigger an attack: alcohol, especially beer and hard liquor; high-purine foods (e. Individuals with gout are typically obese; prone to hypertension, metabolic syndrome,3 and diabetes;4 and at a greater risk for cardiovascular disease. Thiazide and loop diuretics also are associated with a higher risk of incident gout and a higher rate of gout flares. The conventional medical treatment of gout often relies excessively on drugs that inhibit xanthine oxidase. The drug allopurinol, a structural isomer of hypoxanthine (a naturally occurring purine in the body), has been the mainstay treatment for decades. Lead Toxicity A secondary type of gout, sometimes called saturnine gout, can result from lead toxicity. Historically, saturnine gout was caused by the consumption of alcoholic beverages stored in containers with lead in them. An unexpected and fairly common source of lead appears to be leaded crystal; port wine, for example, takes on lead when stored in a crystal decanter. Even a few minutes in a crystal glass results in a measurable increase in the level of lead in wine. While lead levels in the general population have decreased substantially since it was banned from gasoline, those working with aviation fuel are still exposed. The mechanism of action is related to a decrease in excretion of uric acid by the kidneys. Dietary Considerations The dietary treatment of gout involves the following guidelines: • Decreasing purine intake • Eliminating alcohol • Achievement of ideal body weight • Liberal consumption of complex carbohydrates • Low fat intake • Low protein intake • Liberal fluid intake Low-Purine Alkaline-Ash Diet A low-purine diet has been the mainstay of the dietary therapy of gout for decades. Today, however, many physicians prefer to lower uric acid levels by prescribing potent drugs rather than subjecting the patient to the inconvenience and deprivation associated with a purine-free diet. However, dietary restriction of purines is still recommended to reduce metabolic stress. These include organ meats, yeast (brewer’s and baker’s), and smaller ﬁsh such as sardines, herring, and anchovies. These include dried legumes, spinach, asparagus, ﬁsh, meat, poultry, shellﬁsh, and mushrooms. An alkaline-ash diet is recommended in the dietary treatment of gout because a more alkaline pH increases uric acid solubility.
