Because of the patient’s presentation with flank pain that radiates to the groin, we are suspecting renal colic. We should follow guidelines for acute renal management and prescribe IM diclofenac for immediate relief of pain.

Palmar xanthomas are found in type III hyperlipoproteinemia. Her total cholesterol level and triglyceride level support the diagnosis.

Tiotropium is a specific long-acting antimuscarinic agent indicated as maintenance therapy for patients with COPD (chronic obstructive pulmonary disease).
It should be used cautiously in patients with narrow-angle glaucoma, prostatic hyperplasia or bladder neck obstruction.
The most frequently encountered adverse effects of tiotropium include pharyngitis, bronchitis, sinusitis, dry mouth, cough, and headaches. Paradoxical bronchospasm may also occur as a rare side-effect.
Dry mouth occurs in up to 14% of patients taking tiotropium, in keeping with its anticholinergic profile.
Rarer side-effects include tachycardia, blurred vision, urinary retention, and constipation.

Dermatomyositis is a long-term inflammatory disorder which affects muscles. Its symptoms are generally a skin rash and worsening muscle weakness in the proximal muscles (for example, the shoulders and thighs) over time. These may occur suddenly or develop over months. Other symptoms may include weight loss, fever, lung inflammation, or light sensitivity. Complications may include calcium deposits in muscles or skin.
The skin rash may manifest as aheliotrope (a purplish color) or lilac, but may also be red. It can occur around the eyes along with swelling, as well as the upper chest or back ( shawl sign) or V-sign above the breasts and may also occur on the face, upper arms, thighs, or hands. Another form the rash takes is called Gottron’s sign which are red or violet, sometimes scaly, slightly raised papules that erupt on any of the finger joints (the metacarpophalangeal joints or the interphalangeal joints)

CD8+ T cells recognize antigens in the form of short peptide fragments bound to major histocompatibility complex class I (MHCI) molecules on the target cell surface.1 Specific engagement of peptide-MHCI (pMHCI) complexes via the clonotypically expressed αβ T-cell receptor (TCR) triggers a range of effector functions that play a critical role in protective immunity against intracellular infections and various malignancies.

Hepatitis B full vaccine and Ig should be given to babies born to hepatitis B positive mothers. Hepatitis B vaccine alone or Ig alone is not sufficient to prevent the infection in the new-born baby.

Basal cell carcinoma is usually located on sun exposed sites. It has got many variants and clinically it presents as a slow growing mass/nodule with rolled margins and an ulcerated base.

The Koebner phenomenon refers to skin lesions appearing on lines of trauma, exposure to a causative agents including: molluscum contagiosum, warts and toxicodendron dermatitis or secondary to scratching rather than an infective or chemical cause include vitiligo, psoriasis, lichen planus, lichen nitidus, pityriasis rubra pilaris, and keratosis follicularis (Darier disease).

Oesophageal stricture is a complication of systemic sclerosis, think of the oesophagus as sclerosing (fibrosing) leading to stricture and you never forget. Based on the clinical presentation of systemic sclerosis this is more likely than pancreatic dysfunction, PSC, lymphoma, or diverticulitis. Additionally, CREST syndrome stands for: calcinosis cutis, Raynaud’s phenomenon (which the patient has), oesophageal dysmotility, sclerodactyly, and telangiectasias), this is a form of systemic sclerosis you should be familiar with.

Troponin T is a 37 ku protein that binds to tropomyosin, thereby attaching the troponin complex to the thin filament.

The human immunodeficiency virus (HIV) is grouped to the genus Lentivirus within the family of Retroviridae, subfamily Orthoretrovirinae. The HIV genome consists of two identical single-stranded RNA molecules that are enclosed within the core of the virus particle. The genome of the HIV provirus, also known as proviral DNA, is generated by the reverse transcription of the viral RNA genome into DNA, degradation of the RNA and integration of the double-stranded HIV DNA into the human genome.

Adult onset Still’s disease (AOSD) is an uncommon systemic inflammatory disease on the clinical spectrum of autoinflammatory disorders. Its presentation and clinical course may result in several well-differentiated phenotypes: from a systemic and highly symptomatic pattern to a chronic articular pattern. Overproduction of numerous pro-inflammatory cytokines is observed in AOSD. Anakinra, a human interleukin (IL)-1R antagonist, has recently been approved in the treatment of AOSD. Denosumab is a RANK ligand inhibitor used in the treatment of osteoporosis. Mepolizumab is used in the treatment of severe asthma with elevated eosinophils. There is some evidence to support the use of tocilizumab, an anti-IL6 monoclonal antibody in adult onset Still’s, but there is stronger data favouring the use of tocilizumab in the treatment of rheumatoid arthritis. Rituximab is usually reserved for patients who are unresponsive to anakinra.

DIAGNOSIS:
A consensus definition for hemodynamically significant PDA is lacking. The diagnosis is often suspected clinically, when an infant demonstrates signs of excessive shunting from the arterial to pulmonary circulation. Continuous or a systolic murmur; note, a “silent” PDA may also occur when the ductus shunt is large enough that nonturbulent flow fails to generate a detectible murmur.
A low diastolic blood pressure (due to runoff into the ductus during diastole, more frequent in the most premature infants).
A wide pulse pressure (due to ductus runoff or steal)Hypotension (especially in the most premature infants)
Bounding pulses
Increased serum creatinine concentration or oliguria
Hepatomegaly

Steps required in performing the Wilcoxon signed rank test:

1 State the null hypothesis and, in particular, the hypothesized value for comparison
2 Rank all observations in increasing order of magnitude, ignoring their sign. Ignore any observations that are equal to the hypothesized value. If two observations have the same magnitude, regardless of sign, then they are given an average ranking
3 Allocate a sign (+ or -) to each observation according to whether it is greater or less than the hypothesized value (as in the sign test)
4 Calculate:
R+ = sum of all positive ranks
R- = sum of all negative ranks
R = smaller of R+ and R-
5 Calculate an appropriate P value What makes this test the most appropriate for this study is that the data is non-parametric, paired and comes from the same population.

Prednisolone although has many undesirable side effects it may be considered relatively safe compared to the drugs that are provided here. Prolonged treatment with sulphasalazine may depress semen quality and cause irreversible infertility. Methotrexate and leflunomide both inhibit purine/pyrimidine synthesis (the former by inhibiting folate metabolism) and are contraindicated in pregnancy or while trying to conceive. In males, a temporary or permanent decrease in sperm count may occur with cyclophosphamide. Because the recovery of fertility after cyclophosphamide therapy is variable, sperm banking should be considered before treatment is begun.

With a bilirubin of 33, automatically the diagnosis from the choices listed is primary biliary cirrhosis or autoimmune hepatitis, not SLE, mono, or Primary Sjogren’s Syndrome. With autoimmune hepatitis, however, you would not expect such a high bilirubin and would expect very high AST/ALT, which here is just mildly elevated. This makes primary biliary cirrhosis the most likely answer. The classic presentation is itching in a middle-aged woman. The dry mouth is likely due to Sicca Syndrome, which occurs in 70% of cases of PBC, but with these liver function tests, PBC is most the likely answer.

Primary gout is related more often to underexcretion of uric acid or overproduction.

After renal transplant, asymptomatic patients can still have graft dysfunction as an early complication, with rising serum creatinine; therefore, urine and blood cultures should be ordered first. This should be followed by measuring the Tacrolimus levels, as this drug can be directly nephrotoxic. Next, a Doppler ultrasound of the transplant site should be ordered, to check for any obstructions or occlusions.

The diagnosis of polycystic ovarian syndrome (PCOS) is based on hyperandrogenism or chronic anovulation in the absence of specific pituitary and/or adrenal disease.
Pelvic ultrasonography may be very helpful in the evaluation as well, but polycystic ovaries are not specific for PCOS with over 20% of “normal” women having this finding. The number of follicles and ovary volume are both important in the ultrasound evaluation. The criteria for PCOS put forth by Adams et al. are the most often cited: the presence of ≥10 cysts measuring 2–8 mm around a dense core of stroma or scattered within an increased amount of stroma.
A recent proposal to modify these criteria has been put forth by Jonard et al.: “increased ovarian area (>5.5cm2) or volume (>11 mL) and/or presence of ≥12 follicles measuring 2 to 9 mm in diameter (mean of both ovaries)”.
These criteria have a specificity of 99% and a sensitivity of 75% for the diagnosis of PCOS.

According to NICE guidelines (2013) all people who have had an acute MI treatment should be offered with ACE inhibitor, dual antiplatelet therapy (aspirin plus a second antiplatelet agent), a beta-blocker and a statin.

Free T4 levels or the free T4 index is usually elevated, as is the free T3 level or free T3 index
– Assays for thyrotropin-receptor antibodies (particularly TSIs) almost always are positive.
– Detection of TSIs is diagnostic for Graves disease.
– Other markers of thyroid autoimmunity, such as antithyroglobulin antibodies or antithyroid peroxidase antibodies, are usually present.
– Other autoantibodies that may be present include thyrotropin receptor-blocking antibodies and anti–sodium-iodide symporter antibody.
The presence of these antibodies supports the diagnosis of autoimmune thyroid disease.
– The radioactive iodine uptake is increased and the uptake is diffusely distributed over the entire gland.

Hypothermia is defined as a core body temperature of < 35 °C.
Hypothermia may produce the following ECG changes:
-Bradyarrhythmia
-Osborne Waves (= J waves)
-Prolonged PR, QRS and QT intervals
-Shivering artefact
-Ventricular ectopics
-Cardiac arrest due to VT, VF or asystole

Cataract is a condition characterized by clouding of the lens of the eye. This condition most frequently occurs due to age-related degenerative processes in the lens, but can also be associated with ocular trauma, metabolic disorders, side-effects of drugs, or congenital infections. The clouding causes distortion of light, as it passes through the lens, resulting in visual impairment and glare. Initially, a cataract presents discretely and may even go unnoticed, but the visual impairment worsens as the cataract grows larger.

Diagnosis is typically established on the basis of a thorough history and direct visualization of the cataract (by means of slit-lamp microscopy). Surgery is indicated with significant visual impairment and involves lens extraction and implantation of an artificial lens. Untreated cataracts eventually lead to complete blindness.

MDMA commonly known as ecstasy or molly, is a psychoactive drug primarily used as a recreational drug. The desired effects include altered sensations, increased energy, empathy, and pleasure. Features of MDMA abuse include hyponatraemia, tachycardia, hyperventilation, and hyperthermia.

Dermatitis herpetiformis (DH), or Duhring’s disease, is a chronic blistering skin condition,characterised by blisters filled with a watery fluid. Despite its name, it is neither related to nor caused by herpes virus: the name means that it is a skin inflammation having an appearance similar to herpes.
Dermatitis herpetiformis is characterized by intensely itchy, chronic papulovesicular eruptions, usually distributed symmetrically on extensor surfaces (buttocks, back of neck, scalp, elbows, knees, back, hairline, groin, or face)
Dermatitis herpetiformis is an autoimmune condition associated with HLA-DR3.
HLA-A3 is associated with haemochromatosis. HLA-B5 is most commonly associated with Behcet’s disease. HLA-DR4 is associated with both type 1 diabetes mellitus and rheumatoid arthritis. HLA-B27 is most commonly associated with several diseases, most commonly ankylosing spondylitis.

Diagnosis of RA is mainly based on clinical features (e.g., morning stiffness, symmetrical joint swelling) and laboratory tests (e.g., anti-CCP). Rheumatoid factor is not very specific for this disease and hence has low reliability. X-ray findings (e.g., soft tissue swelling or joint space narrowing) occur late in the disease and are therefore not typically used for diagnosis.

Osteoarthritis (OA) is a disabling joint disease characterized by a noninflammatory degeneration of the joint complex (articular cartilage, subchondral bone, and synovium) that occurs with old age or from overuse. It mainly affects the weight-bearing and high-use joints, such as the hip, knee, hands, and vertebrae. Despite the widespread view that OA is a condition caused exclusively by degenerative “wear and tear” of the joints, newer research indicates a significant heterogeneity of causation, including pre-existing peculiarities of joint anatomy, genetics, local inflammation, mechanical forces, and biochemical processes that are affected by proinflammatory mediators and proteases. Major risk factors include advanced age, obesity, previous injuries, and asymmetrically stressed joints. In early-stage osteoarthritis, patients may complain of reduced range of motion, joint-stiffness, and pain that is aggravated with heavy use. As the disease advances, nagging pain may also occur during the night or at rest. Diagnosis is predominantly based on clinical and radiological findings. Classic radiographic features of OA do not necessarily correlate with clinical symptoms and appearance. RA involves proximal interphalangeal joints not distal. Gout occurs as a result of overproduction or underexcretion of uric acid and frequently involves first toe. Fibromyalgia is a disorder characterized by widespread musculoskeletal pain accompanied by fatigue, sleep, memory and mood issues.

European guidelines for the treatment of syndrome of inappropriate antidiuresis include the following recommendations for the management of moderate or profound hyponatremia:
– Restrict fluid intake as first-line treatment.
– Second-line treatments include increasing solute intake with 0.25–0.50 g/kg per day or a combination of low-dose loop diuretics and oral sodium chloride.
– Use of lithium, demeclocycline, or vasopressin receptor antagonists is not recommended.
Recommendations on the treatment of SIADH from an American Expert Panel included the following:
– If chronic, limit the rate of correction.
– Fluid restriction should generally be first-line therapy.
– Consider pharmacologic therapies if serum Na + is not corrected after 24-48 hr of fluid restriction or if the patient has a low urinary electrolyte free water excretion.
– Patients being treated with vaptans should not be on a fluid restriction initially.
– Water, 5% dextrose or desmopressin can be used to slow the rate of correction if the water diuresis is profound.

Asthma is a condition characterized by airway hyperresponsiveness, which results in reversible increases in bronchial smooth muscle tone, and variable amounts of inflammation of the bronchial mucosa.
During an acute asthma attack, the already inflamed airways narrow further due to bronchospasm, which leads to increased airway resistance. Because of the increased smooth muscle tone during an asthma attack, the airways also tend to close at abnormally high lung volumes, trapping air behind occluded or narrowed small airways. Thus the acute asthmatic will breathe at high lung volumes, his functional residual capacity will be elevated, and he will inspire close to total lung capacity. The accessory muscles of respiration are often used to maintain the lungs in a hyperinflated state.

During episodes of acute asthma, pulmonary function tests reveal an obstructive pattern. This includes a decrease in the rate of maximal expiratory air flow (a decrease in FEV1 and the FEV1/FVC ratio) due to the increased resistance, and a reduction in forced vital capacity (FVC) correlating with the level of hyperinflation of the lungs. Because these patients breathe at such high lung volumes (near the top of the pressure-volume curve, where lung compliance greatly decreases), they must exert significant effort to create an extremely negative pleural pressure, and consequently fatigue easily. Overinflation also reduces the curvature of the diaphragm, making it less efficient in generating further negative pleural pressure.

Narrow complex tachycardia with hypotension is a medical emergency. Immediate synchronized cardioversion is the ideal management.
