IRRITABLE BOWEL SYNDROME by Michael Sperling MD
IRRITABLE BOWEL SYNDROME By Michael Sperling MD Irritable bowel syndrome (IBS) involves vague symptoms of abdominal pain, diarrhea, constipation, gas and bloating for which there is no understandable cause. Incredibly, IBS affects up to 20% of the population but only three- quarters of those people actually seek medical attention. It is the second most common reason for work absenteeism. Irritable bowel symptoms may also be related to other complaints such as belching, heartburn, swallowing problems, fullness after eating, nausea, frequent urination, painful menstruation and pain during intercourse. Extremely severe cases can sometimes be related to a history of traumatic abuse. Some common associations or factors: Michael Sperling, MD 1. ‘Spastic colon’ is frequently found along with irritable bowel syndrome. Spastic colon consists of painful muscle contractions which can be relieved by bulk agents or anti- spasm drugs. 2. Post-infectious IBS occurs when irritable bowel follows a gastrointestinal infection, such as the stomach flu. These recurrent symptoms can last up to two years. 3. Stress and anxiety can worsen IBS symptoms so occasionally anti-anxiety agents may be helpful. 4. Food intolerances classically worsen symptoms of irritable bowel in some people. Common “offending foods” include lactose, legumes (beans) and cruciferous vegetables like brussel sprouts, cauliflower, broccoli and cabbage. 5. Hypersensitivity of the bowel wall: Normal colon activity is not usually noticed however in “visceral hypersensitivity”, the bowel wall reacts painfully to normal activity. This condition may be helped by the use of low dose antidepressants, which can block these painful stimuli. Careful and selective testing of patients with these symptoms and the development of a long-term doctor/patient relationship is the key to diagnosing and managing these symptoms. -

Stomach Flu (Viral Gastroenteritis)
Stomach Flu (Viral Gastroenteritis) The stomach flu (also called viral gastroenteritis) is caused by a virus (rotavirus, adenovirus, Norwalk virus to name a few) that affect the stomach and small intestines. It may come on suddenly or over the course of a few hours. The illness is usually brief, lasting 24-72 hours. Symptoms include: Nausea Vomiting Stomach cramps Diarrhea Mild fever Fatigue Body Chills/Sweats Loss of appetite Muscle aches To help take care of yourself: • The best thing to do is to let your stomach rest from solid foods. • Sip on clear liquids (Hi-C, apple, cranberry, and grape juices, Jell-O, Gatorade- type liquids and ginger-ale or ginger tea). There are special properties in ginger that help soothe the stomach. It is extremely important to keep up your hydration. Water is great for hydration but Gatorade-type products are better because they will restore your electrolytes (Sodium, Potassium and Chloride) which are essential for body functions. You may "stir" the bubbles out of the soda if the carbonation is harsh on your stomach. • Once you have not vomited for a few hours and your stomach is feeling better, you may start to eat solid foods. You may try crackers, plain noodles, eggs, broth, pretzels and yogurt. • The BRAT diet (Bananas, Rice, Applesauce & Toast) includes foods that are low in fiber and are easily digested. • Stay away from dairy products, citric (including orange and grapefruit juices), tomato-based & spicy foods. • SLOWLY increase your dietary intake to include fruits, vegetables and meat once symptoms are gone (usually over 2-3 days). -
Improving the Accuracy of Medical Diagnosis with Causal Machine Learning ✉ Jonathan G
ARTICLE https://doi.org/10.1038/s41467-020-17419-7 OPEN Improving the accuracy of medical diagnosis with causal machine learning ✉ Jonathan G. Richens 1 , Ciarán M. Lee1,2 & Saurabh Johri 1 Machine learning promises to revolutionize clinical decision making and diagnosis. In medical diagnosis a doctor aims to explain a patient’s symptoms by determining the diseases causing them. However, existing machine learning approaches to diagnosis are purely associative, 1234567890():,; identifying diseases that are strongly correlated with a patients symptoms. We show that this inability to disentangle correlation from causation can result in sub-optimal or dangerous diagnoses. To overcome this, we reformulate diagnosis as a counterfactual inference task and derive counterfactual diagnostic algorithms. We compare our counterfactual algorithms to the standard associative algorithm and 44 doctors using a test set of clinical vignettes. While the associative algorithm achieves an accuracy placing in the top 48% of doctors in our cohort, our counterfactual algorithm places in the top 25% of doctors, achieving expert clinical accuracy. Our results show that causal reasoning is a vital missing ingredient for applying machine learning to medical diagnosis. 1 Babylon Health, 60 Sloane Ave, Chelsea, London SW3 3DD, UK. 2 University College London, Gower St, Bloomsbury, London WC1E 6BT, UK. ✉ email: [email protected] NATURE COMMUNICATIONS | (2020)11:3923 | https://doi.org/10.1038/s41467-020-17419-7 | www.nature.com/naturecommunications 1 ARTICLE NATURE COMMUNICATIONS | https://doi.org/10.1038/s41467-020-17419-7 roviding accurate and accessible diagnoses is a fundamental Since its formal definition31, model-based diagnosis has been challenge for global healthcare systems. -
Appendicitis
Appendicitis Your child has abdominal pain, it might be appendicitis. Appendicitis is swelling or infection in the appendix. The appendix is a small organ attached to the large intestine. Appendicitis usually develops over 12-24 hours. It has symptoms such as abdominal pain, nausea, vomiting, fever, and loss of appetite. Most importantly, pain that continues, worsens and moves to the right lower side of the abdomen is common in appendicitis. Appendicitis is the most common childhood “emergency” that must be treated in a timely manner. However, it’s important to know that many conditions have symptoms similar to appendicitis but don’t require surgery. At Hasbro Children’s Hospital (HCH), we evaluate your child’s abdominal pain to determine if appendicitis is the cause. That way, we avoid unnecessary operations. What happens now? Your child will be well cared for. First your child will be seen in the HCH emergency department (ED) by a nurse and doctor trained in pediatric emergency medicine. If necessary, your child will have tests that include blood work and a urinalysis. Your child’s pain will be managed with intravenous (IV) pain medication. Your child will not be allowed to eat or drink and may receive fluids through an intravenous line. Members of the pediatric surgical team will examine your child to help determine whether your child has appendicitis or another condition. We will perform a painless ultrasound on your child and the ultrasound images will be read by pediatric radiology doctors with advanced training in imaging children. Usually, ultrasound is the only imaging required but sometimes an MRI may be needed as well. -
Nausea and Vomiting (Stomach “Bug” Or Gastroenteritis)
Nausea and Vomiting •(Stomach Nausea and vomiting “Bug” is most commonly or caused Gastroenteritis) by a viral infection and may be associated with diarrhea. • This illness is self-limited with the majority of people finding improvement within 24-hours and are back to normal by 72-hours after onset of the illness. • This illness can be treated at home and does not require a visit to a medical provider. Symptoms: • Nausea with or without vomiting • Muscle aches • Generalized or upper abdominal pain/cramping • Headache • Watery diarrhea (no blood) • Possible fever Self-care measures: • Stop eating solid foods • Rest • Suck on ice chips or sip small amounts of water on a frequent basis • If you vomit, wait about 20 minutes then resume fluid intake • Slowly increase the amount of fluid intake • Water, Pedialyte® or sports drinks are acceptable • Avoid caffeine, alcohol and carbonated beverages • Acetaminophen (Tylenol®) 650 mg every 6 hours as needed for fever, chills, headache or body aches • Use Imodium for diarrhea lasting more than 2 days Recovery: • You may try solid food when: 1) Nausea and vomiting have resolved 2) You are tolerating fluids 3) You feel hungry When you do eat: • Start with small amounts of simple foods (crackers, toast, Jello®, etc.) • Over the next 24-36 hours slowly build up to your normal diet • Add dairy, high-fat foods, raw vegetables, citrus and red meat last Limit spread to others: • Wash hands with soap and water frequently • Stay home (or in your residence hall) for at least the first 24-hours • If you live in a residence hall call 540-568-6949 to get information about obtaining some appropriate food or fluids When to seek medical attention: • If the vomiting persists more than 24-hours • If you develop bloody diarrhea • If you have obvious pain or tenderness isolated to the right lower abdomen UHC self-care guidelines are based on the most recent recommendations of national medical authorities.. -

Brenneman, M.S.N., C.S., A.N.P., F.N.P. Written documentation for clinical management of patients within health care settings usually include one or more of the following components. - Problem Statement (Chief Complaint) - Subjective (History) - Objective (Physical Exam/Diagnostics) - Assessment (Diagnoses) - Plan (Orders) - Rationale (Clinical Decision Making) Expertise and quality in clinical write-ups is somewhat of an art-form which develops over time as the student/practitioner gains practice and professional experience. In general, students are encouraged to review patient charts, reading as many H/Ps, progress notes and consult reports, as possible. In so doing, one gains insight into a variety of writing styles and methods of conveying clinical information. -
Diagnosing Diagnosis Errors: Lessons from a Multi-Institutional Collaborative Project
Diagnosing Diagnosis Errors: Lessons from a Multi-institutional Collaborative Project Gordon D. Schiff, Seijeoung Kim, Richard Abrams, Karen Cosby, Bruce Lambert, Arthur S. Elstein, Scott Hasler, Nela Krosnjar, Richard Odwazny, Mary F. Wisniewski, Robert A. McNutt Abstract Background: Diagnosis errors are frequent and important, but represent an underemphasized and understudied area of patient safety. Diagnosis errors are challenging to detect and dissect. It is often difficult to agree whether an error has occurred, and even harder to determine with certainty its causes and consequence. The authors applied four safety paradigms: (1) diagnosis as part of a system, (2) less reliance on human memory, (3) need to open “breathing space” to reflect and discuss, (4) multidisciplinary perspectives and collaboration. Methods: The authors reviewed literature on diagnosis errors and developed a taxonomy delineating stages in the diagnostic process: (1) access and presentation, (2) history taking/collection, (3) the physical exam, (4) testing, (5) assessment, (6) referral, and (7) followup. The taxonomy identifies where in the diagnostic process the failures occur. The authors used this approach to analyze diagnosis errors collected over a 3-year period of weekly case conferences and by a survey of physicians. Results: The authors summarize challenges encountered from their review of diagnosis error cases, presenting lessons learned using four prototypical cases. A recurring issue is the sorting-out of relationships among errors in the diagnostic process, delay and misdiagnosis, and adverse patient outcomes. To help understand these relationships, the authors present a model that identifies four key challenges in assessing potential diagnosis error cases: (1) uncertainties about diagnosis and findings, (2) the relationship between diagnosis failure and adverse outcomes, (3) challenges in reconstructing clinician assessment of the patient and clinician actions, and (4) global assessment of improvement opportunities. -
Travelers' Diarrhea
Travelers’ Diarrhea What is it and who gets it? Travelers’ diarrhea (TD) is the most common illness affecting travelers. Each year between 20%-50% of international travelers, an estimated 10 million persons, develop diarrhea. The onset of TD usually occurs within the first week of travel but may occur at any time while traveling and even after returning home. The primary source of infection is ingestion of fecally contaminated food or water. You can get TD whenever you travel from countries with a high level of hygiene to countries that have a low level of hygiene. Poor sanitation, the presence of stool in the environment, and the absence of safe restaurant practices lead to widespread risk of diarrhea from eating a wide variety of foods in restaurants, and elsewhere. Your destination is the most important determinant of risk. Developing countries in Latin America, Africa, the Middle East, and Asia are considered high risk. Most countries in Southern Europe and a few Caribbean islands are deemed intermediate risk. Low risk areas include the United States, Canada, Northern Europe, Australia, New Zealand, and several of the Caribbean islands. Anyone can get TD, but persons at particular high-risk include young adults , immunosuppressed persons, persons with inflammatory-bowel disease or diabetes, and persons taking H-2 blockers or antacids. Attack rates are similar for men and women. TD is caused by bacteria, protozoa or viruses that are ingested by eating contaminated food or beverages. For short-term travelers in most areas, bacteria are the cause of the majority of diarrhea episodes. What are common symptoms of travelers’ diarrhea? Most TD cases begin abruptly. -
Professional Practice Medical Record Documentation Guidelines
Professional Practice Medical Record Documentation Guidelines INTRODUCTION Consistent and complete documentation in the medical record is an essential component of quality patient care. All Participating Providers, defined as primary care and specialist practitioners, are required to keep medical records that contain patient demographics and current, detailed, medical information regarding services rendered to Members to facilitate communication and promote efficient and effective treatment. Medical records must be maintained in an organized medical record-keeping system and in compliance with Capital BlueCross’ documentation standards for Traditional, Comprehensive, PPO, POS, Keystone Health Plan® Central, SeniorBlue® PPO and SeniorBlue® HMO Members. Complete medical records must be maintained for every Member in accordance with accepted professional practice standards, State and Federal requirements. In addition, they must meet the Pennsylvania Department of Health’s guidelines for managed care organizations. Medical records and information must be protected from public access and any information released must comply with HIPAA guidelines. Upon request, all participating practitioners’ medical records must be available for utilization and quality improvement review studies, retrospective review of claims, as well as regulatory agencies’ requests and member relations’ inquiries, as stated in the Provider agreement. Medical records must be available at the practice site for other Providers who provide care and services to the patient. Guidelines have been developed for medical record review that are intended to assist Providers in maintaining complete medical records for all Members. Each provider must meet a minimum 70% compliance with medical record guidelines. If this level of compliance is not met, a corrective action plan will be required. The guidelines, included in Exhibit 3 of this Manual, were developed to comply with state and national regulatory requirements. -
