http://mcqs.com/learn/#/question29-year-old man presents with a cough and some mild aches in the hands, wrists and ankles. The symptoms have been present for 2 months and have increased slightly over that time. Six weeks before he had some soreness of his eyes, which resolved in 1 week.The cough has been non-productive. He had noticed some skin lesions on the edge of the hairline and around his nostrils. Previously he had been well apart from an appendicectomy at the age of 17 years.Examination..............There is no deformity of the joints and no evidence of any acute inflammation. In the respiratory and cardiovascular system there are no abnormal findings. In the skin there are some slightly raised areas on the edge of the hairline posteriorly and at the ala nasae. They are a little lighter than the rest of the skin.Questions1. What is the likely diagnosis????2. How might this be confirmed????

A 33-year-old woman is brought to the emergency department accompanied by her husband. Her husband reports that she has periodic episodes of confusion that quickly resolve. He also reports that she has been extremely weak and fatigued over the last 4 or 5 days. Her temperature is 39.0 C (102.2 F), blood pressure is 140/70 mm Hg, pulse is 103/min, and respirations are 18/min. Physical examination shows jaundiced skin and mild scleral icterus. She has a III/VI systolic ejectionmurmur that does not radiate and 1+ edema in her lower extremities. Laboratory studies show anemia, thrombocytopenia, elevated BUN and creatinine. A peripheral smear shows hemolysis with few platelets.The most appropriate next step is.........A. conservative management with supportive care as neededB. begin high-dose prednisone therapyC. begin large-volume plasmapheresisD. give platelet and red cell transfusionE. obtain a surgical consult for urgent splenectomy

This patient has thrombotic thrombocytopenic purpura (TTP). She has the classic pentad of anemia, thrombocytopenia, neurological abnormalities (which are often waxing and waning), fevers, and renal abnormalities.The treatment is large-volume plasmapheresis daily until the patient is in complete remission. This condition needs to be differentiated from ITP, which typically has isolated thrombocytopenia and hemolytic uremic syndrome (HUS), which is similar to TTP except that renal abnormalities predominate over neurological findings.

Conservation management with supportive care (choice A) is a reasonable option in HUS in children. In the pediatric population, this is typically self limited and only supportive care for acute renal failure is required.

High-dose prednisone therapy (choice B) is a treatment option in ITP. It is thought to work by both decreasing antibody production and by reducing binding of antibodies to platelets. In TTP it is often an adjuvant therapy based on theoretical principles, but it's true role has not been studied.

Platelet and red cell transfusions (choice D) are typically reserved for life-threatening bleeds since it is likely that exogenous platelets and red cells will quickly be destroyed.

Splenectomy (choice E) in combination with steroids is reserved for patients who do not respond to plasmapheresis and would not be the appropriate step at this time

Upper Abdominal Pain:The first question you always ask yourself with abdo pain: IS THEIR PERITONISM OR NOT. If their is, you need to automatically request a surgical consult.With peritoneal pain there will be percussion tenderness, cough tenderness and rebound tenderness. This is a surgical abdomen until proven otherwise. Localized peritonism occurs in area over organ that is inflamed. LIF think diverticulitis, RIF think appendicitis & RUQ think cholecystitis. Generalized peritonism is caused by leakage of blood, bile, bowel contents. Pancreatitis does not typically cause peritonism but can cause ascites.If it is not peritonitis pain you then have to ask yourself whether it is the embryological upper, mid or hind gut that is affected.Upper Abdominal Pain-Gastric - pain can be caused by either: acid - in order to feel better you therefore need to acid. Hence this pain will be relieved with anything which dilutes the acid: Vomiting, Drinking milk, Eating food, Bleeding into the stomach, Antacids.H2 R antagonists or PPIs .Gastroporesis - suspect this if pt reports fullness extending beyond 2 hr postprandial. Succussion splash confirms this - you hear noises when you put your steth on pt stomach and shake their belly. Suction will relieve all gastric pain.Liver: Pain is likely due to liver if there is palpable liver with deranged LFT & jaundice.Tenderness indicates acute hepatitis - pain due to capsule stretching in acute inflammation.If non tender this indicates chronic hepatitis - capsule has had a chance to compensate to slow expansion of liver.Gallbladder: To be considered when liver indicators are absent i.e. no hepatomegaly, normal LFTs, no jaundice. Gallstones will have right hypochondrium tenderness but have a negative Murphys sign.Cholecystitis (gallstones + inflammation) will have right hypochondrium tenderness and a positive Murphys sign.Common bile duct: If inflamed you may get symptoms of cholecystitis i.e. RUQ tenderness + Murphys sign + jaundice + deranged ALP and GGT.Pancreas: Pancreatitis often causes inflammation of the duodenum and being adjacent to the vertebral column pain in the mid thoracic region and pain worsens on vomiting. As the pancreas is retroperitoneal and adjacent to vertebrae, pain is relieved when leaning forward. 1 in 10 patients will have normal pancreatic enzymes so you need to do imaging to confirm dx. Air-filled bowel overlies the pancreas so ultrasound is a terrible way to image it.Do CT or MRI.NB: with pain due to cholecystitis, CBD and pancreas it will be worse on eating as their is increased organ activity in an effort to digest the food and this will irritate.Transverse colon: Pain can be either better or worse on bowel movements.Pt may have diarrhoea or constipation. Tenderness runs in a straight line across the upper abdomen.Abdominal wall:Nerves supplying the wall can be irritated causing pain. Alternatively the pain may be referred from the spine or the chest.Do cardio and resp hx/exam if indicated.Get pt to move spine, percuss along vertebral column
