This scenario represents anorexia nervosa disorder, a psychological disorder. Extreme weight loss with a strict diet can lead to deficiency of many nutrients like magnesium and calcium. This can also cause amenorrhea.

Sudden onset of severe lower back pain whilst is felt more when bending (such as getting up from a bed) is consistent with a diagnosis of a prolapsed intervertebral disc.

Only immunoglobulins are required, as he is already immunized.

Breast carcinoma is one of the most common malignancies in women. It presents as an irregular, firm consistency nodule/lump, which is attached to the skin most of the time. The overlying skin also exhibits a peau d’ orange appearance, along with dimpling. A sebaceous cyst is a small cystic swelling with no colour change and can occur anywhere over the skin. A lipoma is a benign tumour of fats which is soft in consistency.

Both cocaine and heroine withdrawal cause dilated pupils. Heroine withdrawal causes chills.

This clinical picture is typical of chickenpox, which is treated with antihistamines and calamine lotion. In the case of fever, acetaminophen can be used. Generally treatment is purely for symptomatic relief.

Nephrolithiasis encompasses the formation of all types of urinary calculi in the kidney, which may deposit along the entire urogenital tract from the renal pelvis to the urethra. Nephrolithiasis manifests as sudden onset colicky flank pain that may radiate to the groin, testes, or labia (renal/ureteric colic) and is usually associated with haematuria.
Risk factors include low fluid intake, high-sodium, high-purine, and low-potassium diets, which can raise the calcium, uric acid, and oxalate levels in the urine and thereby promote stone formation.
Diagnostics include noncontrast spiral CT of the abdomen and pelvis or ultrasound to detect the stone, as well as urinalysis to assess for concomitant urinary tract infection and serum BUN/creatinine to evaluate kidney function. Urinary stones are most commonly composed of calcium oxalate. Less common stones are made up of uric acid, struvite (due to infection with urease-producing bacteria), calcium phosphate, or cystine.
Small uncomplicated stones without concurrent infection or severe dilation of the urinary tract may be managed conservatively with hydration and analgesics to promote spontaneous stone passage. When the spontaneous passage appears unlikely or fails due to the stone’s size or location, first-line urological interventions include shock wave lithotripsy, ureterorenoscopy, and, in case of large kidney stones, percutaneous nephrolithotomy. The most important preventive measure is adequate hydration.
Collected stones should be sent for chemical analysis because in many cases specific lifestyle guidance, diet changes, and/or initiation of medical treatment (e.g., thiazide diuretics, urine alkalinisation) can prevent future stone formation.

Crohn’s Disease (CD) is an inflammatory bowel disease, the pathogenesis of which is not fully understood. The clinical presentation of CD may be similar to ulcerative colitis (UC), the other most common inflammatory bowel disease. CD mostly affects young adults and adolescents between the ages of 15 and 35. It is typically located in the terminal ileum, but can discontinuously affect the entire gastrointestinal tract and commonly leads to complications such as fistulas, abscesses, and stenosis. Clinical features include diarrhoea, weight loss, and abdominal pain in the right lower quadrant (RLQ), as well as extraintestinal manifestations in the eyes, joints, or skin. It is often difficult to diagnose because there is no confirmatory test. Diagnosis is therefore based on the patient’s medical history, physical examination, lab tests, imaging (e.g., MRI), endoscopy, and serological testing. Acute episodes are treated with corticosteroids, and in severe cases, immunosuppressants may be indicated. Antibiotics and surgical intervention may be needed to help treat complications. Because the entire gastrointestinal tract may be affected, Crohn disease cannot be cured (in contrast to ulcerative colitis). The goal of treatment is thus to avoid the progression and recurrence of inflammatory episodes.

Hormonal contraceptives all contain man-made oestrogen and progestin hormones in a limited amount. These hormones prevent pregnancy by inhibiting the body’s natural cyclical hormones to prevent pregnancy. Even though all of these drugs except Ibuprofen can cause AIP in a vulnerable woman. The most likely cause is the OCP.

According to recent guidelines on asthma management, after administering SABA as needed, low doses of ICS are indicated. In this case the patient already takes budesonide so he now requires a long acting beta agonist (LABA), in this case salmeterol.

The portal vein or hepatic portal vein is a blood vessel that carries blood from the gastrointestinal tract and spleen to the liver. This blood is rich in nutrients that have been extracted from food, and the liver processes these nutrients; it also filters toxins that may have been ingested with the food. 75% of total liver blood flow is through the portal vein, with the remainder coming from the hepatic artery proper.

The condition should be an X-linked recessive condition, as it affects only male offspring. Duchene muscular dystrophy is an X-linked recessive condition. Cystic fibrosis is an autosomal recessive disorder. Spina bifida is a multifactorial condition. Down syndrome is caused by trisomy of chromosome 21. Spinal muscular atrophies are inherited in an autosomal-recessive pattern.

Uterine artery embolization does not require open surgery or GA.

The history is suggestive of ruptured Abdominal Aortic Aneurysm (AAA). Characteristic pain, pulsatile abdominal mass and risk factors such as age>60, hypertension and smoking support the diagnosis. Ultrasonography is the standard imaging tool for AAA. It can also detect free peritoneal blood.

Developing a pelvis abscess is one of the most common postoperative surgical complications after rectal operations. The symptoms of a pelvic mass and fever are also consistent with a pelvic abscess.

Warfarin and Heparin are both anticoagulants, however, warfarin is used to treat chronic conditions, whereas heparin is administered for managing acute conditions (shorter half-life). As this person is about to undergo surgery, anticoagulation can cause excessive bleeding, especially when tissues are cut. Therefore, warfarin will be stopped prior to the procedure and heparin will be administered either subcutaneously or intravenously to prevent formation of any blood clots during surgery but must also be stopped shortly before surgery. As its effect does not last as long as that of warfarin, it can be stopped a shorter time before surgery. Common practice is to give the last dose the evening before surgery.

Calcium channel blockers decrease smooth-muscle contractility in the bladder and this can cause urinary retention.
An enlarged prostate gland could be the reason if he gave a history of obstructive symptoms.
Diabetes presents with polyuria.
Bladder cancer commonly presents with painless haematuria.

Doxycycline is known to cause dyspeptic symptoms. So advising to take Doxycycline after meals is important. Taking with meals or adding an antacid is not advised, as both will cause reduction in drug absorption.

The accessory nerve innervates the trapezius muscle which is involved in shoulder movements. Any injury to this nerve will result in the difficulty of movements around the shoulder.

Barrett’s oesophagus is the abnormal (metaplastic) change in the mucosal cells lining the lower portion of the oesophagus, from normal stratified squamous epithelium to simple columnar epithelium with interspersed goblet cells, normally present only in the colon. This change is considered to be premalignant and is associated with a high incidence of transition to oesophageal adenocarcinoma. Clinical features of carcinoma of the oesophagus include: loss of weight, hoarseness of voice, dysphagia, and cough. Barium swallow and oesophagoscopy with biopsy should be done.

Dysphagia for both solids and liquids indicates either obstruction or impaired oesophageal peristalsis which is usually due to neuromuscular causes such as achalasia. Achalasia is the failure of smooth muscle fibres to relax, which can cause the lower oesophageal sphincter to remain closed. The lower part of the oesophagus is more narrow than normal and presents as a birds beak appearance on barium swallow. If dysphagia was present only on solid food consumption, a benign or malignant tumour must be suspected.

All of the symptoms observed in this patient are typical of bronchial carcinoma.

From the given answers, IBD and IBS are the causes for chronic diarrhoea. Pyelonephritis and ureteric colic are associated with urinary symptoms. Tenderness of pyelonephritis is at the loin region. Perianal disease is associated with fifty percent of patients with Crohn’s disease.

Itching is due to release of histamine locally as a reaction to insect bites. Oral antihistamines are adequate as she doesn’t have other systemic features of anaphylaxis.

The clinical picture of an itchy, scaly annular rash after a walk in the park suggests erythema migrans. The pathogen responsible is a spirochete, Borrelia Burgdorferi transmitted by ticks leading to Lyme disease. Doxycycline is the antibiotic of choice if no contraindications.

Infantile spasm belongs to the spectrum of seizure disorders. Infantile spasm manifests itself with loss of consciousness and jerky movements. The peak age of onset is between 4 and 6 months. Approximately 90% of infantile spasms begin before 12 months of age. It is rare for infantile spasms to begin during the first 2 weeks of life or after 18 months.

Munchausen syndrome by proxy is a mental illness and a form of child abuse. The caretaker of a child, most often a mother or a father, either makes up fake symptoms or causes real symptoms to make it look like the child is sick. The person with MSP gains attention by seeking medical help for exaggerated or made-up symptoms of a child in his or her care. As health care providers strive to identify what’s causing the child’s symptoms, the deliberate actions of the mother or caretaker can often make the symptoms worse.
The person with MSP does not seem to be motivated by a desire for any type of material gain. People with MSP may create or exaggerate a child’s symptoms in several ways. They may simply lie about symptoms, alter tests (such as contaminating a urine sample), falsify medical records, or they may actually induce symptoms through various means, such as poisoning, suffocating, starving, and causing infection.

This presentation is compatible with acute pulmonary oedema probably due to sudden papillary muscle rupture or VSD. Echo should be the answer to establish the underlying cause. It will also help to identify other complications associated with MI.

Candida albicans is the most common cause of candidiasis and appears almost universally in low numbers on healthy skin, in the oropharyngeal cavity, and in the gastrointestinal and genitourinary tracts. In immunocompetent individuals, C. albicans usually causes minor localized infections, including thrush (affecting the oral cavity), vaginal yeast infections (if there is an underlying pH imbalance), and infections of the intertriginous areas of skin (e.g., the axillae or gluteal folds). More widespread and systemic infections may occur in immunocompromised individuals (e.g., neonates, diabetics, and HIV patients), with the oesophagus most commonly affected (candida esophagitis). Localized cutaneous candidiasis infections may be treated with topical antifungal agents (e.g., clotrimazole). More widespread and systemic infections require systemic therapy with fluconazole or caspofungin.

Photosensitivity is a common adverse effect of cardiology drugs including amiodarone and thiazide diuretics. Angiotensin-converting enzyme (ACE) inhibitors and angiotensin 2 receptor blockers (A2RBs) commonly also cause rashes only some of which appear to be photosensitive.
