Thorough understanding of this material is Preoperative Preparation essential for anatomic repair of recurrent hernias and helps the surgeon keep the primary recurrence rate low.

Inadequate closure of the internal ring often follows repair of a large indirect hernia in adults.

Meconium peritonitis usually results from perforation in utero secondary to a congenital stenosis or atresia of the bowel or to meconium ileus. The granular, sand-like calcifications represent metastatic spread throughout the abdomen. The calcifications are located in masses of fibrous tissue surrounding the oil droplets. Clinically, oil granulomas can produce hard palpable masses that simulate carcinomatosis or cause intestinal obstruction. Predisposing conditions include atrophic gastritis, pernicious anemia, gastric polyps, partial gastrectomy, and Ménétrier’s disease.

On physical examination, the patient has open and closed comedones and pimples on her forehead, nose, and cheeks. Cleansing of skin with mild soap Topical therapy used for treatment of comedones and papulopustular acne Benzoyl peroxide Tretinoin (Retin-A): single most effective agent for comedonal acne Adapalene (Differen gel) Topical antibiotics: erythromycin or clindamycin Allow 4–8 weeks to assess effect of above agents Systemic treatment is indicated in those who do not respond to topical agents.

Other major side effect is increased triglycerides and cholesterol: rule out liver disease prior to start and check triglycerides 4 weeks after starting treatment A trial of hormonal therapy can be used in those who are not candidates for isotretinoin. Corticosteroid injections may be used to aid in healing painful nodulocystic lesions. Her father was diagnosed with colon cancer at age 43, and her mother was diagnosed with breast cancer at age 52. She is sexually active with multiple partners and has not seen a physician since a car accident 15 years ago. Screening tests are done on seemingly healthy people to identify those at increased risk of disease. Even if a diagnostic test is available, however, that does not necessarily mean it should be used to screen for a particular disease. Any adverse outcome that occurs (large bowel perforation secondary to a colonoscopy) is iatrogenic. Finally, there may be a stigma associated with incorrectly labeling a patient as “sick. For a screening test to be recommended for regular use, it has to be extensively studied to ensure that all of the requirements are met. The 4 malignancies for which regular screening is recommended are cancers of the colon, breast, cervix, and lung. Other choices include annual fecal occult blood testing and sigmoidoscopy with barium enema every 5 years. In the patient with a single first-degree relative diagnosed with colorectal cancer before age 60 or multiple first-degree relatives with colon cancer at any age, colonoscopy should begin at age 40 or 10 years before the age at which the youngest affected relative was diagnosed, whichever age occurs earlier. Mammography with or without clinical breast exam is recommended every 1–2 years from age 50–74. The American Cancer Society no longer recommends monthly self breast examination alone as a screening tool. Patients with very strong family histories of breast cancer (defined as multiple first- degree relatives) should consider prophylactic tamoxifen, discussing risks and benefits with a physician. In average risk women, Pap smear screening should be started at age 21, regardless of onset of sexual activity. He has no significant past medical history and is here only because his company will not let him travel until he is seen by a physician. The patient appears agitated and demands the physician’s recommendation immediately. It is important to set up a pretravel counseling session 4–6 weeks before the patient’s departure. Hepatitis A infection is possible wherever fecal contamination of food or drinking water may occur. If a patient is leaving within 2 weeks of being seen, both the vaccine and immune serum globulin are recommended. A booster shot given 6 months after the initial vaccination confers immunity for approximately 10 years. Hepatitis B vaccination is recommended for patients who work closely with indigenous populations. Additionally, patients who plan to engage in sexual intercourse with the local populace, to receive medical or dental care, or to remain abroad for >6 months should be vaccinated. It is given once per week; it may cause adverse neuropsychiatric effects such as hallucinations, depression, suicidal ideations, and unusual behavior. Doxycycline is an acceptable alternative to mefloquine, although photosensitivity can be problematic. For pregnant patients requiring chemoprophylaxis for malaria, chloroquine is the preferred regimen. Rabies vaccination is recommended for patients traveling to areas where rabies is common among domesticated animals (India, Asia, Mexico). Therefore, in patients who require malaria prophylaxis, in addition to rabies prophylaxis the intramuscular form of the vaccine should be administered. Typhoid vaccination is recommended for patients who are traveling to developing countries and will have prolonged exposure to contaminated food and water. Typhoid vaccination comes in 2 forms, an oral live attenuated form and a capsular polysaccharide vaccine given parenterally. The polysaccharide vaccine is the preferred form for almost all subjects as it is well-tolerated and convenient (no need for refrigeration). Polio: Adults who are traveling to developing countries and have never received a polio vaccine should receive 3 doses of the inactivated polio vaccine. The live attenuated polio vaccine is no longer recommended because of the risk of vaccine-associated disease. Patients traveling to areas where meningococcal meningitis is endemic or epidemic (Nepal, sub-Saharan Africa, northern India) should be immunized with the polysaccharide vaccine. Patients with functional or actual asplenia and patients with terminal complement deficiencies should also receive the vaccine. To prevent traveler’s diarrhea, patients should be advised to avoid raw and street vendor salads, unwashed fruit, and tap/ice water. Patients who experience mild loose stools without fever or blood can safely take loperamide. Treatment with a fluoroquinolone or azithromycin is reserved for patients with moderate to severe symptoms. Recent serum fasting glucose, serum cholesterol, and blood pressure are all within normal limits. Immunization is the best method available for preventing serious infectious disease. Between 50,000–70,000 adults die every year from preventable infectious disease (influenza, invasive pneumococcal disease, and hepatitis B). Surveys have shown that among patients who have an indication for any vaccination, very few actually receive it (pneumococcal vaccination 20%, influenza 40%, hepatitis B 10%). For this reason, the American College of Physicians recommends that every patient’s immunization status be reviewed at age 50; evaluate risk factors for specific vaccinations at that time.
