Abdominal Pain 407 Summary The list of disease processes that cause abdominal pain is extensive. Most of these maladies never require surgery; however, recognizing when emergent, urgent, or elective operative intervention is required is a necessary skill for general surgeons and most physicians. Starting with a directed history of the nature of the pain and the associated symptoms, one can begin to formulate a differential diagnosis. The past medical and surgical history often provides additional clues as well as a picture of the patient’s overall condition. Understanding that the rigid abdomen seen with free air and the involuntary guarding seen with peritoneal irritation are signs of surgi- cal emergencies is the first step. Further refinement of diagnostic skills comes with the number of abdominal exams one performs. The history and physical combined with laboratory and imaging studies usually provide enough information to determine if the patient has a cata- strophic abdominal emergency, an urgent surgical condition, an elec- tive surgical condition, or a nonsurgical condition. To describe the causes of hepatomegaly; to discuss the role of imaging and liver biopsy; to discuss the most frequently encountered benign and malig- nant liver masses and their management. To describe the differential diagnosis of a pancre- atic mass; to discuss the most useful imaging studies and the role of biopsy. To understand the relationship of the pancreatic duct to the common bile duct and how this may affect the diagnosis and treatment of a pancreatic mass; to discuss the management of cysts of the pancreas. To describe the causes of hypersplenism; to discuss the common signs and symptoms of hypersplenism and contrast with splenomegaly; to discuss the role and consequences of splenec- tomy in the treatment of splenic disease. To discuss the most frequently encountered retroperitoneal masses; to contrast the manage- ment of lymphomas and sarcomas. Cases Case 1 A 46-year-old male police officer noticed mild pressure in his abdomen when he bent to tie his shoes. Further question- ing revealed early satiety, and physical examination revealed a large epigastric mass that was firm but not hard. Physical examination revealed a midline epigastric mass along with an enlarged spleen. Case 4 A 48-year-old man presented with increasing abdominal girth and decreased appetite. Case 5 A 45-year-old man presented with intermittent nausea and blood in his stools. Introduction Abdominal masses may be caused by a large variety of pathologic con- ditions. All abdominal masses need to be thoroughly and expeditiously evaluated, sometimes with significant urgency. A detailed history and physical examination, combined with knowledge of normal anatomy, allow the physician to generate a reasonable differential diagnosis. In certain situations, notably rupturing abdominal aortic aneurysms, the physician must take the patient directly to the operating room without further testing to avoid exsanguination. Several classification systems are available to help guide evaluation of a patient with an abdominal mass (Table 22. Organ based Liver Pancreas Spleen Renal Vascular Gastrointestinal Connective tissue Location based Abdominal wall Intraperitoneal Pelvic Right lower quadrant Left lower quadrant Mid-pelvis Retroperitoneal Flank Epigastric Right upper quadrant Left upper quadrant anatomic systems (Table 22. These systems can be divided into an organ-based system or a location-based system. As always, the physician must be sure the patient does not have an emergency situation requiring immediate operation. General Evaluation A detailed history must include information about the onset of the mass (sudden vs. Neoplastic Benign Malignant Primary Metastatic Infectious Bacterial Parasitic Fungal Traumatic Inflammatory Congenital Degenerative 412 T. These symptoms could include nausea, vomiting, diarrhea, melena, jaundice, vaginal bleeding, and hematuria. The physician should ask about the presence of pain along with details about pain quality, location, radiation, timing, severity, and factors that alleviate or exacerbate the pain. Physical examination should include an evaluation of the patient’s general status, including vital signs and any evidence of impending cardiac or respiratory collapse. Evidence of bowel perforation, such as diffuse abdominal tenderness or tympany from free air, should be sought. Masses that are tender and associated with signs of sepsis (fever, hypotension) or masses associated with perforation require urgent evaluation. Upon completion of the history and physical examination, the physician usually knows if urgent evaluation and treatment are needed or if more leisurely evaluation is safe. Plain radiographs of the chest and abdomen combined with basic laboratory evaluation (com- plete blood count with differential, electrolytes, renal and liver func- tion, urinalysis, pregnancy test) are the first steps in further evaluation. The plain radiographs should include a flat and upright abdominal film along with posteroanterior and lateral chest radiographs. Masses of the uterus and ovaries usually are evaluated initially with ultrasound, either transabdominal or transvaginal. Ultra- sound also is useful for suspected biliary disease as well as for evalua- tion of nonurgent abdominal aortic aneurysms. Cystoscopy is useful for bladder evaluation and should be included in any evaluation of hematuria. Angiography occasionally is used in the evaluation of operative approaches for abdominal masses. Mag- netic resonance angiography is an evolving technique that may provide similar information less invasively than angiography. Liver Masses Liver masses may present with symptoms or may be discovered inci- dentally on scans done for other reasons. Tumors Cysts Abscesses Benign Acquired Pyogenic Hemangioma Parasitic (hydatid) Adenoma Traumatic Focal nodular hyperplasia Malignant: primary Congenital Amebic Hepatoma Single Cholangiocarcinoma Multiple Angiosarcoma Malignant: metastatic Fungal Unresectable Resectable tenderness could represent an infectious etiology, such as abscess. A personal history of cancer, particularly colon and rectal cancer, could be a clue to hepatic metastases. Patients with a history of alcoholism or hepatitis leading to cirrhosis are at risk for hepatocellular cancer. His occupation as a police officer may have exposed him to blunt abdominal trauma while arresting a suspect. The patient’s symptoms were managed with mild analgesics, and the decision was made to avoid surgical resection in this patient. Heman- gioma is the most common benign tumor of the liver, occurring in up to 20% of patients in some autopsy series. They usually are asympto- matic and require removal only if disabling symptoms are present. Other benign tumors include hepatic adenomas associated with oral contraceptive use in young women. Hepatic adenomas that are symptomatic or larger than 5cm usually are removed due to the 10% to 20% chance of subsequent rupture.

After your pets have stopped eating propyl alcohol polluted food and are not getting propyl alcohol in their shampoos epivir-hbv 150 mg without a prescription medicine hat weather, there is no way they can get cancer generic epivir-hbv 150 mg with amex medicine zalim lotion. Whatever cancer they have will clear up by this change in diet and by giving them the pet parasite program epivir-hbv 150 mg on-line medicine naproxen. By selecting wise habits your improved lifestyle pays you back for the rest of your life buy epivir-hbv 150mg on-line symptoms questions. After using the bathroom and washing your hands, treat your fingernails with alcohol. Add ½ cup 95% alcohol to ½ cup cold tap water or buy plain vodka, 80 to 100 proof. Ask your pharmacist to make it from scratch for you (there are only two ingredients and water, see Recipes). In long-ago days, all sheets, towels, table cloths, and underwear were separated and boiled. With the convenience of our electric washing machine, we tend to overlook the fact that underwear is always contaminated by fecal matter and urogenital secretions and excretions. Lime water (calcium hydroxide) or iodine based antiseptics seem obviously simple methods to accomplish this. Besides, your skin absorbs it from clothing, it is quite toxic to you, and can cause mental effects. They do not clean quite as well as modern detergents, but there is less static cling, eliminating the need to put more chemicals in your dryer. Better Kitchen Habits Once a day, sterilize the sponge or cloth you use to wipe up the table, counter tops and sink. This little piece of contami- nated cloth is the most infectious thing in the house, besides the toilet. Sometimes it has a slight odor at first, which may warn you, but most pathogens do not have an odor! As we wipe up droplets of milk, we give the milk bacteria, Salmonellas and Shigellas, a new home to multiply and thrive in. The cloth or sponge recolonizes the kitchen and dining room table several times a day. No doubt, the last thing you do before leaving the kitchen is squeeze it dry with your hands. In two hours they are already multiplying in the greatest culture system of all: your body! To sterilize the sponge: drop it into a 50% solution of grain alcohol at the end of each day. Another way to sterilize the sponge or cloth is to microwave it, after wetting it, for 3 minutes. Another strategy is to use a fresh cloth or sponge each day, putting the used one to dry until laundry day. The counter and table top have on them whatever is in the kitchen dust and on the wipe cloth. Vacuuming sends up a hurricane of dust and distributes bathroom dust to the kitchen and kitchen dust to the bedrooms. So if one person has brought in a new infection, the whole family is exposed to it in hours via the dust. The newly contaminated dust drops into your ready and waiting glasses on the table and the open foods. Teach children to cough and sneeze into a suitable col- lecting place like a tissue, not their hands. If you must cough or sneeze and a tissue is not within reach fast enough, use your clothing! Never, never your hands unless you are free to immediately dash into the washroom and clean the contamination off your hands. Teach children this old rearranged verse: If you cough or sneeze or sniff Grab a tissue, quick-quick-quick! Better Housekeeping Throw out as much of the wall to wall carpeting as you can bear to part with. Modern shoes, with their deep treads, bring in huge amounts of outdoor filth which settles deep down into the carpets. When you see how much filth is in the water and realize how much dirt you were living with, you might be willing to trade in the “beauty” of carpets for the cleaner living of smooth floors. Cobalt, which adds “lustre” to carpets, causes skin and heart disease after it has built up in your organs. Nothing controls fleas reliably, except getting rid of the carpets and cloth furniture (keep pets out of bedrooms). Fleas and other vermin in the carpet simply crawl below the wetness level when you wash the carpet. Spraying a grain alco- hol solution with lemon peel in it (it needs to extract for a half hour) on the damp carpet will reach and kill a lot of these, to- gether with the residual bacteria. Molds and bacteria that grow right on the air conditioning unit get blown about for all to inhale. Never, never use fiberglass as a filter or to insulate your air conditioner around the sides. All dirt brought into the house by shoes gets circulated throughout the house by forced air systems of heating or cooling. A return to linoleum floor covering for kitchen and bathroom and hardwood for other rooms would be a good step of progress for a health conscious society. Throw rugs at doors and bedside, easy to clean, would “catch the dirt” as was the original intention. Modern cloth furniture with its foam interior is a repository of filth and fumes and a constant source of infectious dust. You are picking up and removing highly infectious filth (Ascaris and pinworm eggs, pet parasites, “dander” and house mites). Use plain water or vinegar water (50%), not a chemical combination which further pollutes the air. In places like Chicago where you can smell the air as you approach the city, it is wiser to keep your windows shut. Central air conditioning and a plain carbon filter at the furnace location (see Sources) may be the best solution in spite of blowing dust around the house. Keep the vents to the bedrooms closed to re- duce the air turbulence there but leave the cold air return open. Clean the vents in other rooms each week along with floors and carpets by pulling up the grating and reaching down the passage as far as possible. If you believe the air is free of highway exhaust and indus- trial smoke open the windows every day. Asbestos, fiberglass, freon, radon and plain dust can be reduced to a minimum by keeping windows open. Buy such small quantities that you can afford to throw it all away when you are done with them. Move to the other end of the house and furthest away from an attached garage door. Getting Rid of Mites We do not tolerate external parasites like bedbugs, lice, ticks, leeches. Lice were originally “controlled” by frequent washing, louse combs, and ironing the seams of clothing. Never allow a pet into the bedroom or the dust will have tapeworm eggs as well as mites. Deep, soft, wall to wall carpets compromise an ancient concept: everything should be washable and cleanable, without throwing the dirt into the air for humans to inhale. Never shake bedding or rugs where the dust will blow back into the house behind you.

I regard it as one of the most certain of the vegetable diuretics 150 mg epivir-hbv medications diabetes, and employ it frequently for this purpose epivir-hbv 150 mg otc symptoms for bronchitis. In suppression of urine in children buy discount epivir-hbv 150 mg line medicine lake montana, a teaspoonful of the tincture is added to two ounces of water 150 mg epivir-hbv with mastercard stroke treatment 60 minutes, sweetened, and given freely. So certain is its action in childhood, that I rarely think of giving anything else, except in cases where there is great irritation of the nervous system, and then Gelseminum is added to it in the usual doses. I have employed it topically, and with much success, in local inflammations, as rheumatism, neuralgia, erysipelas, burns, etc. I have likewise administered the remedy internally in rheumatic and neuralgic affections, with apparent benefit. A spray of the tincture made with dilute alcohol has given me most excellent results in the treatment of obstinate bronchitis. I have not been able to test it as fully as could be desired, though I hope ere long to be furnished with a new and larger amount. The principal object of this communication is to call the attention of our physicians to the plant, that they may thoroughly investigate its virtues. The Mitchella exerts a direct influence upon the reproductive apparatus of the female, giving tone and improving functional activity. It has been extensively used as a uterine tonic, to promote menstruation, to remove false pains and unpleasant sensations in the latter months of pregnancy, and has been thought to be a good preparative to labor, rendering the birth of the child easier, and less liable to accidents. Many have failed to obtain these influences from the use of the common preparation, “Compound Syrup of Partridgeberry,” because it was prepared from old materials. We especially want to know its influence upon the nervous system, and its action as a sedative. It evidently possesses medicinal properties, and I have seen good effects from its local use. It is claimed to be poisonous when taken internally, yet I have known it taken with safety in doses of ten to thirty drops. The limited use I have known made of it internally was to relieve muscular pains, lame back, and stiffness of joints. As the agent is very common, and easily cultivated, it would be well to prepare a tincture from the fresh fruit, ℥viij. Of such a preparation the dose would be quite small, say commencing with one drop. Solve the extract (imported from Brazil) in dilute alcohol, or in water, adding alcohol sufficient to preserve it. The Monesia is a mild stimulant and tonic, and may be given in atonic dyspepsia, in convalescence from the malarial fevers, in chronic diarrhœa, chronic bronchitis, and incipient tuberculosis. Anstie (The Practitioner, December, 1868), which treats principally of the employment of this remedy for the relief of (1) various kinds of pain, and (2) of certain cases of suspended secretion dependent on nervous exhaustion. Before very briefly describing some of the applications mentioned, we think it right to state that we are by no means prepared to coincide in Dr. Under the first class the disease termed myalgia is said to be specially amenable to treatment by Muriate of Ammonia. Doses from ten to twenty grains are recommended, and by their use this disease may be cured as certainly as ague by quinia. This class also includes various neuralgias proper, such as migraine (usually referred to disorders of digestion) and clavus hystericus; both of which Dr. Of all the internal remedies that can be employed in these headaches, none is apparently so beneficial as the Muriate of Ammonia, its virtue depending on its mildly stimulant properties. As the Bayberry deteriorates unless carefully kept, it would be better to test a tincture of the fresh bark of the root. It has been extensively employed as a general stimulant, and as a special stimulant to mucous membranes, and with excellent results. Thomson recommended it in all cases where there was increased secretion from mucous membranes, whether it was catarrh or sore throat, bronchitis, disease of stomach or intestinal canal, or leucorrhœa. The same combination will prove very valuable in typhoid fever, in typhoid dysentery, and in diarrhœa with increased mucous secretion. The tincture prepared as above will furnish a much better form of dispensing, as well as a more reliable remedy than much of the powder sold, and when once used, will become a prominent agent in the office and the pocket case. Dusted over a larded cloth, it sometimes makes a good application to the bowels in cholera infantum, and over the stomach to check vomiting. As a local application myrrh may be used for spongy and ulcerated gums, chronic pharyngitis, where the mucous membrane is pallid and tumid, elongation of uvula, and spongy and enlarged tonsils. Internally it is given in chronic gastritis and dyspepsia, the tongue and mucous membranes being pallid and full, and to rectify wrongs of the reproductive apparatus, there being a sense of weight and dragging, with leucorrhœa. It was claimed to be specific to the poison of the rattlesnake, and to have been used with much success. It influences the nervous system directly, and experiment may develop a valuable use for it. It is not in the market, and we will therefore have to depend upon those who can procure it green, to determine its properties. It has been employed in epilepsy, in diseases showing epileptiform movements of the muscles, in chorea, and in rheumatism with unpleasant muscular contraction. It may also be given (in small dose) in diseases of the brain, the eyes being dull and the pupils dilated. Employed in the form named, it will give satisfaction and well repay its preparation. A teaspoonful added to four tablespoonfuls of hot water and sweetened, may be given freely, and is better than a tea of the dried herb. Unzicker, of this city, recommends the preparation of a tincture from the green plant, and its use as a sedative and in the treatment of diseases of the respiratory apparatus of children. We value the local use of tobacco as a fomentation in cases of strangulated hernia, in some acute local inflammations, and in pseudo- membranous croup when the danger is imminent. It will also prove the best application to wounds and injuries where there are symptoms of tetanus. In tetanus the alkaloid, Nicotine, has been employed with marked success, and it is probably our most certain remedy. It is given in doses of half to one drop, or if not tolerated by the stomach, it may be used by hypodermic injection. If the alkaloid can not be procured, an infusion may be used by mouth, by injection, or if not retained in sufficient quantity in these ways, it may be given by hypodermic injection. The preparation advised is the “Aqua Nicotianæ Tabacum Spirituosæ Rademacheri,” for which a formula is given. This preparation is recommended highly in affections of the brain accompanying fever, in rheumatismus acutus fixus et vagus, in other affections of the brain and spinal marrow, in cholera morbus, and in cholera Asiatica. To prepare it: Take of choice fresh green leaves of Nicotianæ Tabacum eight pounds, and cut them finely. The leaves are to be cut and the distillation effected immediately after they are pulled, with great care that there shall be no over-heating of the liquid, as, if the liquor be over heated it will have a very disagreeable odor of tobacco, which it does not have when the water is properly prepared. The great majority of cases treated with this mixture recovered immediately from the attack. In those cases where the attack was followed with a typhoid condition, he gave: ℞ Tinct. There are certain conditions of disease in which Nitric Acid is a very valuable remedy, and if it is possible to tell when it is indicated it will prove one of the most valuable of our specifies. There is a certain condition of stomach, in which there is irritability with enfeebled function, in which Nitric Acid is the remedy. And there is a lesion of digestion and blood-making other than the derangement of the stomach named, in which Nitric Acid is a direct remedy. There is also added to this, or separate from it in some cases, an impaired nutrition as well as a slow and imperfect retrograde metamorphosis of tissue and failure of excretion, in which Nitric Acid will prove a direct remedy.
