Involves critical thinking in a way that evaluates new data to support the hypothesis and reduce alternative hypothesis. This is done by evaluating all the avenues to reach a conclusion that gives the best evidence to support the main theory or hypothesis. b. Examples of diagnostic reasoning are problem solving, health promotion, and screening for disease or illness. All of these will require sensitivity, complexity, contest, and a sense of probability and uncertainty. 2. Discuss and identify subjective & objective data a.

Breathing, heart rate, Central and peripheral nervous systems, Body weight, Muscle strength, Menstrual cycles, Body temperature, Cholesterol levels All types of hyperthyroidism are a result of overproduction and/or secretion of thyroid hormones, and the clinical manifestations of hyperthyroidism are a direct result of the effect of excessive thyroid hormones on essentially all organ systems and bodily tissues. Although thyroid hormones are required to regulate normal growth and development, excessive release of T4 and T3 from the thyroid into the circulation upregulates metabolism, leading to an increase in total body heat production, heart rate and contractility, and vasodilation. This explains the clinical manifestations of thyrotoxicosis, which include palpitations, diaphoresis, heat intolerance, and anxiety. T3 is normally 20 to 100 times more biologically active than T4, which is converted to T3 in peripheral tissues. Interestingly, the degree of symptomatology does not consistently correlate with the extent of thyroid hormone overproduction. In general, younger patients tend to have symptoms more reflective of sympathetic activation (tremors, anxiety, and hyperactivity), whereas older patients manifest more cardiovascular symptoms, including atrial fibrillation and dyspnea, as well as weight loss. 16. Describe a goiter and the type of thyroid dysfunction that can be associated with it -A goiter is the hypertrophy and hyperplasia of the thyroid gland in response to TSH levels. Most commonly seen with Hashimoto’s thyroiditis (hypothyroidism) in the United States. Toxic multinodular goiter (hyperthyroidism) in iodine deficiency. Grave’s Disease (hyperthyroidism) has a firm goiter 17.Differentiate between overt hypothyroidism and subclinical hypothyroidism- Overt hypothyroidism o TSH above 10 and FT4 is decreased o Too little hormone is being produced o Pituitary is attempting to get the thyroid to produce more Low FT4 and high TSH - Subclinical hypothyroidism o TSH levels are increased, but the FT4 is within range o Some have symptoms, others do not 18. Differentiate between Hashimoto’s thyroiditis and Grave’s disease.Both are autoimmune, attacking thyroid cells. Graves – overproduction of thyroid leading to hyperthyroidism - 90% of hyperthyroidism cases Hashimoto’s – underproduction of thyroid leading to hypothyroidism -Identified via TPO and TBG Abs in blood 19.

Differentiate between resting, postural and intention tremors and describe each Resting tremor -Occurs at rest, against gravity, or sitting still with arms resting in lap. The most common condition that causes resting tremors is Parkinson’s Disease and medication tremors. Postural tremor-Seen when the patient is asked to extend the arm in front of them. The most common type is an essential tremor. It's bilateral and generally symmetric. There’s often a family Hx. Drinking alcohol can reduce the tremor. Intention (Kinetic) tremor-Characterized by an increase in amplitude when the patient attempts movement. Can be checked by having the patient perform finger to nose coordination. 2. Describe one disease with resting tremor as a clinical finding Parkinson’s Disease. It is a progressive neurological disease - 4 hallmark signs: o resting tremor o cogwheel rigidity o bradykinesia, o postural instability - Other characteristics are facial masking, difficulty standing from sitting in a chair, “freezing”, reduced arm swing, festinating (quick, short stride, with head down) and shuffling gait. Wilson's disease is another condition that is associated with resting tremor. This is a very rare genetic disorder associated with copper toxicity. Patients who are affected may have extrapyramidal symptoms [similar to Parkinson's] with a slow and progressive course. There may be symptoms of incoordination in the hands, dysarthria, and gait disorder, bradykinesia, rigidity, and ophthalmologic changes. The work up for Wilson’s includes serum ceruloplasmin and copper. Diagnosis is confirmed with liver biopsy, which identifies the copper toxicity. Treatment is aimed at lowering copper levels. 3. Describe a medication commonly associated with tremors Extrapyramidal side effects similar to Parkinson's disease. Antipsychotics are the most common offending agent. Metoclopramide (Reglan) Phenothiazine - Compazine Steroids Caffeine Anti-epileptics Antidepressants Asthma medications Intention tremor may be associated with medications, alcohol or drug abuse, multiple sclerosis, stroke, or a mass affecting the cerebellum. 4. Identify at least 3 laboratory tests to rule out systemic causes of tremor Electrolyte/ABGs (metabolic imbalances, drugs, caffeine, physiological fatigue) Serum glucose (hypoglycemia) Toxicology screen/drug levels (toxic conditions, antipsychotic drugs, caffeine) 5. Describe at least one at-risk population that is recommended to have HIV screening Anyone who had unprotected sex should be screened for HIV Men who have sex with men Those who exchange sex for drugs/money Those who have other STIs IV drug users Healthcare workers 6. Describe at least one pharmacologic treatment option for tremor Primidone (Mysoline) - beta blocker benzodiazepine (lorazepam) If monotherapy is ineffective, REFER TO NEURO If the tremor is medication induced, that agent may be reduced or eliminated. Parkinson’s disease - Dopamine agonist o Carbidopa/levodopa (Sinemet) o Pramipexole (Mirapex) o Ropinirole (Requip) - Anticholinergics 9. Identify physical exam findings in the patient with HIV Infection should be considered in patients who present with the more typical signs and symptoms, including an ill-defined febrile illness, heterophile-negative mononucleosis-like syndrome, heterophile positive mononucleosis in an unusual host (for example, an older adult patient), and/or aseptic meningitis. *Early HIV infection should also be considered in patients who have had a recent high- risk exposure or those who have had a recent sexually transmitted infection (particularly syphilis), regardless of the presence of symptoms or signs. 10.Describe symptoms, DDx, pathogens, testing, and treatment for the following conditions: Cellulitis, impetigo, MRSA, Bites (dogs, cats, humans), Erysipelas Cellulitis · acute infection as a result of bacterial entry via breaches in the skin barrier. · As the bacteria enter the subcutaneous tissues, their toxins are released which causes an inflammatory response. · Cellulitis involves the deeper dermis and subcutaneous fat. · Cellulitis is observed most frequently among middle-aged individuals and older adults. · The vast majority of pathogens associated with cellulitis are from either Streptococcus or Staphlococcus bacteria. · The most common are beta-hemolytic streptococci (groups A, B, C, G, and F), and S. aureus. Symptoms: · Cellulitis may present with or without purulence · Both erysipelas and cellulitis manifest with areas of skin erythema, edema, warmth and pain. · Fever may be present. · Additional manifestations of cellulitis and erysipelas include lymphangitis and inflammation of regional lymph nodes. · Edema surrounding the hair follicles may lead to dimpling in the skin, creating an appearance reminiscent of an orange peel texture called "peau d'orange". · indolent course with development of localized symptoms over a few days. Treatment · Many patients with cellulitis have underlying such as tinea pedis, lymphedema, and chronic venous insufficiency · should be directed at both the infection and the predisposing condition if modifiable. · Patients with cellulitis should be managed with empiric therapy for infection due to beta- hemolytic streptococci and methicillin-susceptible Staphylococcus aureus (MSSA) with: · Cephalexin 500 mg four times daily (alternative for mild penicillin allergy) · Clindamycin 300 mg to 450 mg four times daily (alternative for severe penicillin allergy) · Patients with cellulitis typically have symptomatic improvement within 24 to 48 hours of beginning antimicrobial therapy. Impetigo · a superficial bacterial infection of the skin. · primary impetigo when there is a direct bacterial invasion of previously normal skin · secondary impetigo when the infection arises at sites of minor skin trauma. o impetiginization. · most frequently observed in children ages 2–5 years of age, although older children of any age and adults may also be affected. · The infection usually occurs in warm, humid conditions and is easily spread among individuals in close contact. · Risk factors include poverty, crowding, poor hygiene, and underlying scabies. Source · S. aureus. · Group A Streptococcus (GAS) causes a minority of cases, either alone or in combination with S. aureus. · Occasionally, MRSA is detected in some cases of impetigo. Variants of impetigo ● Nonbullous impetigo—Nonbullous impetigo is the most common form of impetigo and begins as papules that progress to vesicles surrounded by erythema. Within a week, the papules eventually become pustules that enlarge, break down, and form thick, adherent crusts with a characteristic golden appearance. Lesions usually involve the face and extremities. Regional lymphadenitis may occur, although systemic symptoms are usually absent. ● Bullous impetigo—Bullous impetigo is seen primarily in young children in which the vesicles enlarge to form flaccid bullae with clear yellow fluid, which later becomes darker and ruptures, leaving a thin brown crust. The trunk is more frequently affected. Bullous impetigo in an adult with appropriate demographic risk factors should prompt an investigation for previously undiagnosed human immunodeficiency virus (HIV) infection. ● Ecthyma—This form of impetigo, caused by group A, beta-hemolytic Streptococcus (Streptococcus pyogenes), consists of an ulcerative form in which the lesions extend through the epidermis and deep into the dermis. Ecthyma resembles "punched-out" ulcers covered with yellow crust surrounded by raised violaceous margins. Complication · Poststreptococcal glomerulonephritis is a serious complication of impetigo (ecthyma). o This condition develops within 1–2 weeks following infection. Poststreptococcal glomerulonephritis manifests with edema, hypertension, fever, and hematuria. diagnosis · Made on the basis of clinical manifestations · A Gram stain and culture of pus or exudate is recommended to identify whether S. aureus and/or a beta-hemolytic Streptococcus is the cause. · Infections with methicillin resistant Staphylococcus aureus (MRSA), as the name indicates, are those caused by strains of Staphylococcus aureus that developed a resistant to methicillin shortly after the introduction of this medication in England in 1961. · Methicillin resistance is mediated by a penicillin-binding protein that permits the organism to grow and divide in the presence of methicillin and other beta-lactam antibiotics. Risk factors for community-associated methicillin- resistant S. aureus (CA-MRSA) · Antibiotic use secondary to antibiotic selective pressure. o Use of cephalosporins and fluoroquinolones strongly correlates with the risk for MRSA colonization and infection. ● HIV infection ● Hemodialysis ● Long-term care facilities CA-MRSA transmission · direct contact with a colonized or infected individual. · contact with contaminated fomites used by an affected individual. · Individuals colonized with MRSA serve as a reservoir for transmission. · MRSA can colonize the skin and nares of hospitalized patients, healthcare workers, and healthy individuals. · Colonization can occur from inhalation of aerosolized droplets from chronic nasal carriers. CA-MRSA isolates · most often associated with skin and soft tissue infections (SSTIs). Signs and symptoms · skin abscess-collection of pus within the dermis or subcutaneous space. · painful, fluctuant, erythematous nodule, with or without surrounding cellulitis. · Spontaneous drainage of purulent material may occur. · Regional adenopathy may be observed. · Fever, · chills, · systemic toxicity are unusual. · furuncles (abscessed hair follicles or "boils") · carbuncles (coalesced masses of furuncles). The diagnosis of a skin abscess is usually based upon clinical manifestations. Laboratory testing is not required for patients with uncomplicated infection in the absence of comorbidities or complications. ~Blood cultures should be obtained prior to the initiation of antibiotic therapy when the lesion is secondary to animal bites or water-associated injuries. ~ Differential should include the following. ● Epidermoid cyst—A skin-colored cutaneous nodule, often with a central punctum, that is freely movable on palpation. Epidermoid cysts may become secondarily infected. ● Folliculitis—Defined as inflammation of one or more hair follicles. ● Hidradenitis suppurativa—A chronic suppurative process involving the skin and subcutaneous tissue of intertriginous skin. ● Recluse spider bites. However, CA-MRSA SSTIs are far more prevalent than spider bites. ~Patients with drainable abscess should undergo incision and drainage with C&S. ~For patients undergoing incision and drainage of a skin abscess, some experts suggest antibiotic treatment under some conditions. ● Single abscess ≥2 cm ● Multiple lesions ● Extensive surrounding cellulitis ● Associated immunosuppression or other comorbidities ● Systemic signs of toxicity (fever >100.5° F/38° C) ● Presence of an indwelling medical device (such as prosthetic joint, vascular graft, or pacemaker) ● High risk for transmission of aureus to others (such as in athletes or military personnel) Antibiotics with coverage for CA-MRSA include the following. ● Bactrim DS twice daily ● Doxycycline 100 mg twice daily ● Minocycline 200 mg orally once, then 100 mg orally every 12 hours ● Clindamycin 300 mg to 450 mg four times daily Treatment should be offered for at least 5 days. **A beta-lactam drug should be added if the abscess is perioral or perirectal. Dog Bites · Soft tissue trauma caused by animal and human bites have serious clinical implications because of the potential for complications. · Animal bites are more common among children than among adults. · Dog bites can cause a range of injuries from minor to major complicated wounds. · The extremities, particularly the dominant hand, are the most frequent site of injury in older children or adults. The predominant pathogens in animal bite wounds are the oral flora of the biting animal and human skin flora. Therefore, infection usually results from a mixture of organisms. Common pathogens include of dog bites ● Pasteurella; ● Staphylococcus; ● Streptococcus species; and ● Capnocytophaga canimorsus, clinically significant in asplenic patients, chronic alcohol abusers, and those with underlying hepatic disease. Cat Bites · About two thirds of cat bites involve the upper extremities. · Deep puncture wounds are of particular concern because cats have long, slender, sharp teeth. · Cat bites can transmit Pasteurella and Bartonella henselae. Human bites · a semicircular or oval area of erythema or bruising is usually visible; · the skin itself may or may not be intact. · Bites by humans occur in two basic categories. · Occlusive wounds, more common in females, with teeth closing over and ~Amoxicillin/clavulanate 875 mg/125 mg twice daily is the agent of choice. ~Alternative antibiotics include one of the following agents with activity against Pasteurella. ● Doxycycline 100 mg twice daily ● Bactrim DS twice daily ● Penicillin VK 500 mg four times daily ● Ciprofloxacin 500 mg twice daily PLUS one of the following agents with anaerobic activity. ● Metronidazole 500 mg three times daily ● Clindamycin 450 mg three times daily ~First-generation cephalosporins and macrolides should be avoided. ~The duration of prophylactic oral antibiotics is 3–5 days, with close follow-up. ~Tetanus toxoid should be given to those who have completed a primary immunization series but who received the most recent booster 5 or more years ago. ~Patients with mild infection can be treated initially with the same prophylactic antibiotics for 5 to 14 days of therapy. Erysipelas ● involves the upper dermis, and there is clear demarcation between involved and uninvolved tissue. ● Erysipelas occurs in young children and older adults ● Erysipelas results almost always results from a group A strep infection Symptoms • Both erysipelas and cellulitis manifest with areas of skin erythema, edema, warmth and pain. • Fever may be present. • Additional manifestations of cellulitis and erysipelas include lymphangitis and inflammation of regional lymph nodes. • Edema surrounding the hair follicles may lead to dimpling in the skin, creating an appearance reminiscent of an orange peel texture called "peau d'orange". • erysipelas is non-purulent. • acute onset of symptoms with systemic manifestations including fever and chills, • Erysipelas lesions are raised above the level of surrounding skin with clear demarcation between involved and uninvolved tissue. • Classic descriptions of erysipelas note "butterfly" involvement of the face. • Involvement of the ear (Milian's ear sign) is a distinguishing feature for erysipelas, since this region does not contain deeper dermis tissue. Treatment • Patients with erysipelas should be managed with empiric therapy for infection due to beta- hemolytic streptococci with: • Penicillin V potassium 500 mg orally every 6 hours • Amoxicillin 875 mg twice daily • Cephalexin 500 mg four times daily (alternative for mild penicillin allergy) • Clindamycin 300 mg to 450 mg four times daily (alternative for severe penicillin allergy)
