If thyroid bruit is present cheap medrol 4mg with visa arthritis reactive treatment, check whether it is a murmur of aortic stenosis (ejection systolic murmur) radiating from chest buy cheap medrol 4mg on-line lupus arthritis in feet. For thyroid status purchase 4mg medrol with amex rheumatoid arthritis diet soda, look for the signs of thyrotoxicosis and signs of hypothyroidism purchase medrol 4 mg mastercard arthritis pain tylenol or advil. Signs of thyrotoxicosis: • See tremor of outstretched hands with fngers spread out. Signs of hypothyroidism: Puffy face with periorbital swelling with baggy eyelids, loss of outer 1/3rd of eyebrows and • apathetic look. A: Exophthalmos, lid lag, lid retraction and eye movement (see exophthalmos on page 510). A: Other physical fndings (not related to toxicosis): • Legs: Pretibial myxoedema (present only in Graves’ disease). A: It is a sign to detect retro-sternal extension of thyroid gland (also positive with any retrosternal mass). On raising both arms above the head, the patient with retro-sternal extension may develop the following signs of compression: • Face: Suffusion or congestion and cyanosis. Lid lag Lid retraction Pretibial myxoedema Onycholysis in Graves disease mebooksfree. Remember the following points: • Eye signs (exophthalmos, periorbital oedema, chemosis and diplopia), pretibial myxoedema and thyroid acropachy are present only in Graves’ disease. However, lid lag and lid retraction occurs in thyrotoxicosis, which are due to sympathetic overactivity, which supplies levator palpebrae muscle. It may be present both in hyper or hypo or euthyroid state associated with Graves’ disease. Then ask history of excessive sweating or heat intolerance, history of palpitation, diarrhoea, appetite and weight loss. Look from head to foot, observe generalized swelling of the body and non-pitting oedema). Case 1: Graves disease Case 2: Myxoedema Case 3: Graves disease Case 4: Myxoedema (non-goitrous) (hypothyroid) (goitrous, Hashimoto’s thyroiditis) Presentation of a Case (Myxoedema): Case No. Presentation of a Case: • Thyroid gland is diffusely enlarged (or nodular or multinodular), 7 3 6 cm, non-tender, frm in consistency, freely mobile, no retrosternal extension, no palpable lymph node. There may be atrial fbrillation, ectopics and high volume pulse in thyrotoxicosis. Toxic multinodular goitre Cachexia in thyrotoxicosis Apathetic thyrotoxicosis Q:What else do you want to examine? A: As follows (mention the causes of that case by looking at face and neck): • In young patient with diffuse goitre and exophthalmos, the likely cause is Graves disease (even if no exophthalmos, still it can be Graves disease). Thyroiditis (subacute thyroiditis, also called De Quervain’s thyroiditis and post-partum thyroiditis. If any patient complains of loss of weight despite good appetite, the likely diagnosis is thyrotoxicosis (other cause may be diabetes mellitus. A: Causes of thyrotoxicosis with low radioiodine uptake: • Subacute thyroiditis (De Quervain’s thyroiditis). A: 3 modes of treatment: Drugs (carbimazole and propylthiouracil), radioiodine therapy and surgery. Carbimazole or propylthiouracil: reduce the synthesis of thyroid hormones by inhibiting the iodination of tyrosine. When the patient is euthyroid, reduce the dose, then 5 to 20 mg daily for 18 to 24 months. Disadvantages of drugs: • Relapse in 50% cases within 2 years of stopping the drug (surgery or radioiodine or long term drug therapy may be needed in such case). Complication of drugs: • Carbimazole can cause hypersensitive skin rash and agranulocytosis (0. Other side effects are nausea, vomiting, arthralgia, jaundice (May be started in low dose to see skin rash. It has small but defnite risk of hepatotoxicity, may result in liver failure requiring liver transplantation and even death. So, it should be considered second line therapy, only to be used during pregnancy or breastfeeding, or if side effects of carbimazole. Radioiodine therapy: It acts by destroying the functioning thyroid cells and inhibiting their ability to replicate. In severe cases, carbimazole may be given, which should be started 48 h after radioiodine therapy. Indications of radioiodine therapy: • Usually, above 40 years of age (however, may be used in young). Contraindications of radioiodine therapy: • Pregnancy or planned pregnancy within 6 months of treatment. Disadvantages of radioiodine therapy: • Hypothyroidism: It occurs in 40% in frst year and 80% in 15 years. In women of reproductive age, pregnancy must be excluded before administration of 131I and • avoided for 6 months thereafter. Men are also advised against fathering children for 6 months after receiving 131I. It inhibits thyroid hormone release, reduces the size and vascularity of gland, making surgery easier. In toxic nodular or multinodular goitre, treatment of choice is radioiodine therapy or surgery. It is due to hypoka- laemia (caused by entry of potassium into the cell), common in Asians. It may occur following excess of carbohydrate or glucose or heavy exercise and persists for 7 to 72 hours. It is treated in the following ways: • b-Blocker: Propranolol (digoxin has little role). A: It is characterized by life threatening increase in signs and symptoms of thyrotoxicosis (also called thyroid storm). A: Deliberate intake of thyroxine to reduce weight, usually in emotionally disturbed person. Thyroglobulin level is zero or low, high ratio of T4:T3 5 70:1 (in conventional thyrotoxicosis, the ratio is 30:1). Combination of neg- ligible radioiodine uptake, high T4:T3 ratio and low thyroglobulin is diagnostic. Only features may be unexplained weight loss or cardiac features such as atrial fbrillation, tachycardia or heart failure, which masks thyrotoxicosis. Children may present with excess growth, behaviour problem like hyperactivity and increase in weight rather than loss. In most of the cases, hyperthyroidism may be present before pregnancy (either known or subclinical).

I have been so fortunate to have you as my one and only editor for these Case Files books. To my dedicated colleagues in academic family medicine who inspire me to become a greater teacher and clinician. Your positive reception has been an incredible encourage­ ment, especially in light of the short lif of the Case FilesC series. In this furth edi­ tion ofCase FilesC: Family Medicine, the basic frmat of the book has been retained. New cases include Substance Abuse, Asthma, Sleep Apnea, Osteoporosis, Chronic Pain Management, and Leg Swelling. We reviewed the clinical scenarios with the intent of improving them; however, their "real-lif" presentations patterned afer actual clinical experi­ ence were accurate and instructive. Through this furth edition, we hope that the reader will continue to enjoy learning diagnosis and management through the simulated clinical cases. It certainly is a privilege to be teachers fr so many students, and it is with humility that we present this edition. Bruce Britton, who is an excellent teacher and communicator, and most recently Dr. Joel Heidelbaugh, who has a amazing breadth of knowledge and brings a fesh perspective. I am greatly indebted to my editor, Catherine Johnson, whose exuberance, experience, and vision helped to shape this series. I am thankfl to Raghavi Khullar fr the outstanding and precise project management. Most of all, I appreciate my ever-loving wif Terri, and fur wonder­ fl children, Andy and his wif Anna, Michael, Allison, and Christina fr their patience, encouragement, and understanding. It is even more difcult to draw on that knowledge, procure, and flter through the clinical and laboratory data, develop a diferential diagnosis, and, fnally, to frm a rational treatment plan. To gain these skills, the student ofen learns best at the bedside, guided and instructed by experienced teachers, and inspired toward self-directed, diligent reading. Unfrtunately, clinical situations usually do not encom­ pass the breadth of the specialty. Perhaps the best alternative is a careflly crafed patient case designed to stimulate the clinical approach and decision making. In an attempt to achieve that goal, we have constructed a collection of clinical vignettes to teach diagnostic or therapeutic approaches that are relevant to fmily medicine. Most importantly, the explanations fr the cases emphasize the mechanisms and underlying principles, rather than merely rote questions and answers. This book is organized fr versatility to allow the student"in a rush" to go quickly through the scenarios and check the corresponding answers, as well as enable the student who wants thought-provoking explanations to take a slower path. The answers are arranged fom simple to complex: a summary of the pertinent points, the bare answers, an analysis of the case, an approach to the topic, a comprehension test at the end fr reinfrcement and emphasis, and a list of resources fr frther reading. The clinical vignettes are purposely placed in random order to simulate the way that real patients present to the practitioner. The Summary identifes the salient aspects of the case, fltering out the extra­ neous infrmation. The student should frmulate his/her summary fom the case befre looking at the answers. Objectives of the Case: A listing of the two or three main principles that is crucial fr a practitioner in managing the patient. Again, the student is challenged to make educated "guesses" about the objectives of the case upon initial review of the case scenario, which help to sharpen his/her clinical and analytical skills. Considerations: A discussion of the relevant points and a brief approach to the specifc patient. Defnitions or Pathophysiologyi Terminology or basic science correlates that are pertinent to the disease process. Clinical Approachi A discussion of the approach to the clinical problem in general, including tables, fgures, and algorithms. Approach to the Patient Applying "book learning" to a specifc clinical situation is one the most challenging tasks in medicine. To do so, the clinician must not only retain infrmation, organize fcts, and recall large amounts of data but also apply all of this to the patient. The frst step involves gathering infrmation, also known as establishing the database. This includes taking the history, perfrming the physical examination, and obtaining selective laboratory examinations, special studies, and/ or imaging tests. Sensitivity and respect should always be exercised during the interview of patients.

The doctor attempts to supinate the affected arm with the elbow in flexed position buy medrol 16mg with mastercard arthritis medication for labradors. She attempts three times but fails to hear a click and the child is still in pain and holding her arm close to her body purchase medrol 4 mg with visa arthritis dogs natural. Reattempt reduction maneuvers until a click is heard and patient can move her arm order 16mg medrol free shipping arthritis in the knee natural remedies. The father states he fell asleep on the couch and when he awoke the patient was crying and lying next to the playpen in which he had been placed earlier purchase medrol 16mg arthritis pain sharp or dull. Which of the following is the most appro- priate next step in the management of this child? On physical examina- tion, the left shoulder is warm and tender to palpation, and has decreased range of motion. A child with nursemaid’s elbow holds the arm close to his body with the elbow flexed and forearm pronated. Treatment consists of supinating the child’s forearm with the elbow in a flexed position while applying pressure over the radial head. Initial management includes two to four attempts about 15 minutes apart in an attempt to reduce the annular ligament. Should the expected improve- ment not be seen, radiographs of the affected extremity are indicated. A 3-month-old child would not be able to climb out of a playpen to sus- tain the injuries his father stated. The next step is to perform a detailed history and physical examination, followed by a skeletal survey (full-body radiographs) to assess for old or new injuries in the infant. If further questions remain, admission to the hospital and notification to Child Protective Services are indicated. The next step is to aspirate the joint and send labora- tory tests on the joint aspirate. Passive movement of the affected arm results in pain, and the child will resist movement of the arm. His mother says he had been playing when she noticed small red spots and a large purple area on his skin. He is playful on examination, but he has multiple petechiae and pur- puric lesions on his upper and lower extremities and on his trunk. Considerations This 3-year-old has purpuric lesions and petechiae resulting from thrombocytope- nia. A peripheral blood smear is examined to identify large normal platelets, but in diminished numbers. This child has a platelet count of 20,000/mm3 and lacks evidence of active bleeding; the next step is close observation. Causes of thrombocytopenic include decreased plate- let production, platelet sequestration, or increased platelet destruction. The syndrome may have dermatologic (petechial/purpuric rash), renal (nephritis), gastrointestinal (abdominal pain, gastrointestinal bleeding, intussusception), and joint involvement (arthritis). The evidence suggests an immunologic etiology trig- gered by a preceding viral illness with subsequent development of an autoantibody directed against the platelet surface resulting in a destructive thrombocytopenia. Young children usually pres- ent with acute onset of petechiae and purpura, and often a history of a viral illness 1 to 4 weeks previously. Bleeding from the gingivae and other mucous membranes may occur if platelet levels are severely low (typically <10,000/mm3). Examination findings most often include petechiae and purpura, especially in trauma areas. If sig- nificant lymphadenopathy or organomegaly is found, other causes for thrombocytopenia are considered. Patients with severe thrombocytopenia (<20,000/mm3), extensive mucosal bleeding, severe complications (eg, massive gastrointestinal bleeds), or without a protective environment may require medical intervention. Treatment is typically not initiated and close observation alone is a well-accepted treatment option for patients with minimal or mild symptoms. Options include intravenous immunoglobulin for 1 to 2 days, intravenous anti-D therapy, or a 2- to 3-week course of systemic corticosteroids. Splenectomy may be considered in children with serious complications not responding to other therapies. After splenectomy, pneumococcal vaccine and penicillin prophylaxis are required because of risk for sepsis. Within a month of presentation, more than half of untreated children have com- plete resolution of their thrombocytopenia and up to another 30% have resolution by 6 months. Many pharmacologic agents may cause immune-mediated thrombocytopenia, including penicillins, trimethoprim-sulfamethoxazole, digoxin, quinine, quinidine, cimetidine, benzodiazepine, and heparin. She was diagnosed with a urinary tract infection 4 days ago, which is being treated with trimethoprim-sulfamethoxazole. He is nontoxic appearing, but he has palpable petechiae on his lower extremi- ties and buttocks. His right knee is mildly edematous and he can bear weight on his right leg, but complains of pain. He was well until the preceding week, when he had fever, vomiting, and bloody diar- rhea (now resolved). On examination, he is lethargic and has hepatospleno- megaly and scattered petechiae. If no lymphadenopathy or organomegaly is found, the peripheral blood smear is normal, and there is no evidence of severe bleeding, initial management includes close observation and a protective environment. The thrombocytopenia may be because of the trimethoprim-sulfamethox- azole; the medicine is discontinued and her platelet count is monitored. Gastrointestinal complications include hemorrhage, obstruction, and intussusception; abdominal pain requires careful evaluation. Patients have pallor, lethargy, and decreased urine output; some have hepatosplenomegaly, petechiae, and edema. Acute renal failure is manifested by hematuria, proteinuria, and an elevated serum creatinine level. Management is supportive with care- ful monitoring of renal and hematologic parameters; dialysis may be required. He lives with his mother, step father, 21-month-old sister, and 3-year-old brother. Recognize that child abuse is suspected if significant inconsistencies exist between the physical injury and the trauma history. It is imperative that the child’s developmental level be assessed regarding the child’s possible role in an accidental injury. Considerations The lack of trauma history is very concerning in this infant who is not mobile. The mother’s delay in seeking medical care for 7 days from symptom onset is concern- ing.

Synovial fluid cultures usually are sterile in gonococcal arthritis (in fact purchase medrol 16mg line zyrtec arthritis pain, the arthritis is more likely caused by immune complex deposition than by actual joint infect ion) discount medrol 4 mg line rheumatoid arthritis systemic, and blood cultures are posit ive less t han 50% of t he time 16 mg medrol fast delivery rheumatoid arthritis in neck treatment. Diagnosis is more often made by finding gonococcal infection in a more typical site purchase medrol 16 mg free shipping arthritis diet and treatment, such as urethra, cervix, or pharynx. C o r t ico st er o id s sh o u ld n o t b e u sed u n t il in fect io n is r u led o u t. T h e in flam - matory arthritis as shown by Gram stain of the joint aspirate is suspicious for infect ion, even wit h no organisms seen on Gram st ain. Inflammatory fluid (white blood cell count more than 2000/mm ) should be considered infected until proven otherwise. Calcium pyro- phosphate dihydrate crystals in pseudogout are rhomboid and positively birefringent (blue). Joint pain and stiffness are making it harder for her to get out of bed in the morning and are interfering with her ability to perform her duties at work. She also reports malaise and easy fatigability for the past few months, but she denies having fever, chills, skin rashes, and weight lo ss.

He ad, n e ck, card iovascular, ch e st, an d ab d om in al examin ation s are normal. It s major dist inct ive feature is a ch ronic, symmet ric, and erosive synovit is of peripheral joint s, which, if unt reated, leads to deformity and destruction of joints due to erosion of cartilage and bone. If t he only finding is pain wit hout inflamma- tory changes, then the diagnostic considerations include noninflammatory diseases such as ost eoart hrit is (O A), fibromyalgia, hypot hyroidism, neuropat hic pain, and depression. If there is active synovitis/ arthritis, it is clinically useful to distinguish between monoarticular/ oligoarticular arthritis (see Case 33) and polyarticular arthritis. If symp- toms are relatively acute (< 6 weeks), the major considerations are arthritis due to viral infection (such as hepatitis B or C, rubella, or parvovirus B19) or the earliest manifestation of a true rheumatic disease. Viral serologies and compatible clinical history of exposure often can make the diagnosis at this point and obviate need for fu r t h er r h eu mat ologic evalu at ion. Rheumatic fever, which can cause symmetric polyarthritis, is an acute febrile illness lasting only 6 to 8 weeks. The vast majority of patients have peripheral joint involvement of more than five joints. Inflammation is not limited to the joints but also occurs at the periosteum, along tendons, and at the insertion points into the bone, resulting in the development of “s a u s a g e d i g i t s, ” w h i c h a r e t y p i c a l o f p s o r i a t i c arthritis ( and Reiter syndrome). Alt h ou gh the ar t h r it is can pr ecede the development of a skin rash, the definite diagnosis of psoriatic arthritis cannot be made without the evidence of skin or nail changes typical of psoriasis (nail pitting, scaly plaques). Reiter syndrome is a form of reactive arthritis with the triad of arthritis, uveitis, and urethritis. Degenerative joint disease may affect multiple joints, but it occurs in older age groups, is usually not associated with inflammation or constitutional symptoms, and tends not to be episodic. Morning stiffness or st iffness aft er any prolonged inact ivit y is a common feature of many arthritic disorders. Rheumatoid nodules are subcutaneous nodules typically found over extensor surfaces of t he proximal ulna or ot her pressure point s. Usually, though, the typical x-ray findings do not develop until later in the disease process after a diag- nosis has been made based on clinical findings. The structural damage to the joint is irreversible and worsens with disease progression. At this st age in the disease process, our pat ient is present ing wit h joint com- plaints, fatigue, and malaise. Usually, the development of extra-articular phenomenon allows the physician to make a more specific diagnosis. Corticosteroids have an immediate and dramatic effect on joint symptoms, but were historically thought not to alter the natural progression of the disease. Recent evidence suggests that low-dose corticosteroids may retard the progression of bone erosions. Physical examinat ion shows warmth and swelling of both knees with large effusions. Arthrocen- tesis of the right knee reveals the presence of intracellular and extracellular weakly positive birefr ingent cr ystals in the syn ovial flu id. Physical examinat ion shows exquisit e t enderness of t he joint, wit h swelling, warmt h, and eryt hema. Synovial fluid analysis and aspirat ion are most likely t o show wh ich of the following?

T h e in volvem en t of the gr eat t oe is m ost likely gou t, an d the syn ovial flu id is likely t o show needle-shaped, negatively birefringent crystals.

Her examination is remarkable for normal vital signs; a swollen, deformed right distal forearm and wrist, with limited mobility because of pain; and good radial pulses and capillary refill in the right fingernail beds. An x-ray confirms a fracture of the right radial head, and the radiologist notes osteopenia.
