CXR and abdominal film interpretation for medical studentPatinya Yutchawit
1. The document provides guidance on interpreting chest x-rays and abdominal films through a systematic approach.
2. Key steps include evaluating technique and quality, checking for abnormalities in the airways, lungs, heart, diaphragm and other delicate areas. Common lung diseases and findings are described.
3. Interpreting abdominal films involves checking for bowel gas patterns, soft tissue masses, fluids, calcifications and bone abnormalities. Relating densities seen to different tissues helps with interpretation.

Chest CT can play an important role in evaluating patients with COVID-19 and detecting alternative diagnoses or complications. Common CT findings of COVID-19 include ground-glass opacities, vascular enlargement, bilateral lung involvement especially in the lower lobes, and a posterior predominance. CT may show normal findings early in infection but often demonstrates progressive abnormalities from ground-glass opacities to consolidation over the course of illness. Complications seen on CT include acute respiratory distress syndrome, pulmonary embolism, superimposed pneumonia, heart failure, and pericardial effusions.
This document provides guidelines from the American Society for Gastrointestinal Endoscopy on the role of endoscopy in evaluating patients with dyspepsia. It recommends that patients over 50 years old or those exhibiting alarm features should undergo endoscopic evaluation, while those under 50 without alarm features can be initially treated with noninvasive H. pylori testing and treatment if positive or a short course of PPIs. For patients who do not respond to or have recurring symptoms after these initial approaches, endoscopy is recommended to exclude structural diseases. The guidelines aim to optimize the use of endoscopy for diagnosing conditions like peptic ulcer disease or malignancy while avoiding unnecessary endoscopies.
Avascular necrosis, also known as osteonecrosis or bone infarction, is the death of bone tissue due to a lack of blood supply. It most commonly affects the femoral head. There are many potential causes including trauma, alcohol use, steroid use, and idiopathic cases. Diagnosis is made through imaging like x-rays, CT scans, MRIs, and bone scans. Treatment depends on the stage of necrosis and other factors, and may include observation, core decompression, vascularized bone grafts, partial or total hip replacement, or hip resurfacing. Staging is important for determining treatment and can range from pre-symptomatic changes visible only on MRI to complete femoral head destruction indistinguishable from osteo
This document summarizes various shoulder injuries including sprains, dislocations, tendinitis, fractures, and nerve injuries. It describes the mechanisms of injury, signs and symptoms, special tests used for diagnosis, and recommends referring patients to an orthopedist. Key details are provided for sternoclavicular joint sprains, acromioclavicular joint sprains, glenohumeral dislocations, rotator cuff injuries, bicep tendon injuries, clavicle and scapula fractures, and thoracic outlet syndrome.
Tokyo guidelines for cholangitis and cholecystitis Thorsang Chayovan
The document presents the Tokyo Guidelines for the management of acute cholangitis and cholecystitis. It was created by an international working group to address the lack of standardized diagnostic criteria and treatment guidelines for biliary infections. The working group conducted an extensive literature review, found little high-level evidence, and thus developed the guidelines through international consensus meetings. The Tokyo Guidelines provide evidence-based diagnostic criteria, severity assessments, and management recommendations for acute cholangitis and cholecystitis. They aim to establish international standards for evaluating and treating biliary infections.
The role of ercp in diseases of the biliary tract and pancreasThorsang Chayovan
This document provides guidelines from the American Society for Gastrointestinal Endoscopy (ASGE) on the role of endoscopic retrograde cholangiopancreatography (ERCP) in diseases of the biliary tract and pancreas. It was developed using an evidence-based methodology including a literature review. The guidelines are intended to apply to all physicians performing GI endoscopy. ERCP is described as useful for diagnosing and treating conditions like gallstones, biliary strictures, pancreatic disease, and leaks or injuries to the biliary tract. Outcomes of ERCP for various conditions are discussed along with appropriate patient selection and techniques.
This guideline discusses the appropriate use of endoscopy in evaluating patients with dyspepsia. It recommends that patients over 50 years old or those with alarm features should undergo endoscopy due to their higher risk of structural diseases like cancer or peptic ulcers. Younger patients without alarm features may initially receive noninvasive testing for H. pylori infection and be treated if positive, or try acid suppression therapy. If these approaches do not resolve symptoms, endoscopy is recommended to check for structural causes. The guideline aims to help clinicians determine which dyspepsia patients most need endoscopy versus other initial treatment strategies.
This document provides guidelines for the role of endoscopy in evaluating suspected choledocholithiasis (gallstones in the common bile duct). It recommends a risk-stratified approach based on initial evaluation. For low risk patients, only cholecystectomy is needed. For intermediate risk, additional imaging like EUS, MRCP or preoperative ERCP is recommended to further evaluate need for ductal stone removal. For high risk, preoperative ERCP or operative cholangiography is recommended due to frequent need for therapy. Non-endoscopic options like CT, MRCP, IOC and laparoscopic ultrasound are also discussed. The guidelines are meant to help endoscopists provide care while considering individual clinical factors.
This clinical guideline provides recommendations for diagnosing and treating pneumonia in children. Pneumonia is common in children under 2 years old and can be caused by bacteria, viruses, or mixed infections depending on the child's age. Clinical features like fever, cough, difficulty breathing, and fast breathing should prompt consideration of pneumonia. Chest x-rays are not needed for most cases but can help in complicated cases. Most children can be treated with oral antibiotics at home, while those with more severe symptoms require hospital admission and intravenous antibiotics. Complications like lung abscesses may occur and require longer treatment and follow up to ensure full recovery. Recurrent pneumonia may indicate underlying conditions that require further investigation.
This document provides guidelines for treating fever and neutropenia in children with cancer. It defines low-risk and high-risk patients based on their condition and symptoms. For low-risk patients, initial treatment with ceftazidime is recommended, while high-risk patients should receive ceftazidime and vancomycin. Treatment is modified based on blood culture results and patient stability. Persistent fever may warrant adding antifungal drugs or investigating non-bacterial causes.
Rectal procidentia, or rectal prolapse, is the full-thickness circumferential intussusception of the rectum through the anal verge. It can be incomplete involving just the mucosa, or complete involving the full rectal wall. Complete prolapse is classified as first degree if the prolapse remains outside the anus, second degree if it reduces spontaneously on lying down, or third degree if it requires manual reduction. Predisposing factors include constipation, pelvic floor weakness, rectocele, and increased intra-abdominal pressure. Treatment options include pelvic floor repair, rectopexy to elevate the rectum, and resection of redundant sigmoid colon.
The document discusses acute calculous cholecystitis, a complication of gallstones where the gallbladder becomes inflamed. It provides details on the pathogenesis, symptoms, diagnosis and treatment strategies. Regarding treatment strategies, it indicates that early laparoscopic cholecystectomy within 1 week of symptoms starting is considered the best treatment for most patients based on randomized trials showing shorter hospital stays compared to delayed surgery 2-3 months later. However, it notes the risk of bile duct injuries may be higher for early surgery on an inflamed gallbladder based on large registry studies, though randomized trials were too small to definitively assess this risk. It concludes that while early laparoscopy is usually best, open surgery or postponing surgery may
