And so, a happy ending.

It always makes me smile to see things work out.

  1. What evidence is there for a genetic cause of autism?
  1. Other than genetics, what other things may cause autism?

Autism’s False Prophets Questions

I’ve been having a difficult time logging into ‘Blackboard’ today to post the questions for chapter 10 of Autism’s False Prophets. Although I don’t like posting any required material here, I’d rather get it out there, so if you are in my pathology class, please spread the word to other students to check in here.

Before you start, check out this video mentioned towards the back of the chapter…

Autism’s False Prophets                                                                           Name:

Chapter 10 Questions

Science and Society

“For many parents, the advice given by heathcare professionals about vaccines is just one more opinion in a sea of opinions offered by the internet.”

-Offit, chapter 10

  1. What is the problem with Dan Burton’s assessment of what he saw at the Stop Autism Now Conference?
  1. How would you interpret the actions of policymakers at the CDC who ‘invariably give these vaccines to their own children and grandchildren’? If you have read Offit’s other book, Vaccinated, do you recall who vaccine maker, Maurice Hilleman, insisted were the first to receive the Hepatitis vaccine made from human blood?
  1. What does Offit say is even more important than reporting the source of funding for scientific investigation on? Why is this so?
  1. What is ‘the price’ of empowering parents to make medical decisions about their childrens’ healthcare?
  1. How does the ‘Scientific Method’ differ from what people often do in their day-to-day lives? How is it similar?
  1. Using the scientific method, data serves to _____________________________ the null hypothesis. What can it NOT do? Why not?
  1. Why is it evolutionarily successful to make ‘the best connections’? What flaws in logic can this leave?
  1. What quotation did Stephen Strauss, former director of NCCAM keep framed on his office wall? What is the meaning of this quotation?
  1. How many people, since 1958, have died from poisoned Halloween candy? (http://www.snopes.com/horrors/poison/halloween.asp)

Case Study

IndianJRadiolImaging_2013_23_1_81_113621_u3A 25 yo man presents at the ER with abrupt, intense pain in the right flank and ipsilateral lower abdomen. In addition to abdominal pains, he also feels  pain in the right testicle and has had to urinate frequently and always with pain. Imaging was done to aid in assessment.

Given this information, what diagnosis might you suggest? Explain the symptoms and what is revealed by the imaging. What treatment do you suggest?

Invitation to submit questions for Renal System Exam … and a quick extra credit opportunity

As always, I invite students and non-students to submit multiple choice questions appropriate for the upcoming exam on the Renal System (Physiology and Pathophysiology questions). Post questions with answers (three wrong and one right) in the comments section below.

Also, here’s an opportunity for two points of extra credit on the upcoming exam:

Submit your answer quick – only the first correct response (also posted in comments) earns points. I will try to post several more questions over the weekend – note, these extra credit vignettes may come from any of the chapters we studied this semester)

Presentation

A 62 year old man presented at the ER with sudden sensation of food being caught in his throat while swallowing. The patient is highly agitated and convinced he is choking although he appears to be getting air.

LESAn emergency endoscopy reveals food stuck in the esophagus. With pressure, food bolus passed into the stomach successfully. A subsequent barium swallow and X Ray produced the image here.

What is the diagnosis?

Invitation to Submit Questions for Respiratory Unit

As I’ve been doing lately, I wanted to offer the opportunity to my students (and anyone else who would like to) to submit questions for the Respiratory Unit Exam of my Pathophysiology class. Topics covered on this exam will focus primarily on the outline below. However, I wish to remind students that they are responsible for all the material covered in chapters 21-23 of Porth’s Essentials of Pathophysiology.

Airways preserved in the right lung, airways and pulmonary circulation in the left lung.

Airways preserved in the right lung, airways and pulmonary circulation in the left lung.

To submit questions, please provide a fully worked out multiple choice question in the comments section below. Also indicate the correct answer.

Respiratory Pathophysiology Outline (Please, forgive the formatting below, I’m having trouble fixing this appropriately in the browser):

  1. Control of Respiratory Function
    1. Conducting Airways
      1. Nasopharynx
      2. Larynx
  • Trachea
  1. Bronchial Tree (Primary -> Terminal)
  1. Respiratory Tissue (Acini)
    1. Respiratory Bronchiole
    2. Alveoli
      1. Type I, Type II Alveolar Cells and Alveolar macrophages
    3. Pulmonary (And Bronchial) Circulation
    4. Pleura
    5. Ventilation and the Mechanics of Breathing
      1. Chest Cage and Respiratory Muscles
      2. Lung Compliance
    6. Lung Volumes and Capacities
      1. Total Lung Capacity
      2. Tidal Volume
  • Etc.
  1. Diffusion according to Fick’s Law
  2. Oxygen Delivery
    1. Oxygen / Globin Dissociation Curves
  3. Infections
    1. The Common Cold
      1. Caused by a number of different viruses
      2. A number of different serotypes
    2. Influenza
      1. One of the most deadly uncontrolled human infections
      2. Three types of influenza (A,B, and C – A is most diverse)
        1. Influenza A
          1. Distinguished by serotypes based on H&N genes
  • Three types of infections
    1. Uncomplicated upper respiratory disease
    2. Viral Pneumonia
    3. Viral Pneumonia + Bacterial Pneumonia
  1. Pneumonia
    1. Typical*
      1. Bacterial ( pneumoniae)
    2. Atypical*
      1. Viral (Influenza, Chickenpox), Fungal, protozoan
  • Legionnaire’s Disease
    1. (I find that pneumonia caused by Legionella is placed as either typical or atypical depending on the source)
  1. Fungal Infections
  2. Tuberculosis
    1. Diagnosis
    2. Treatment
  3. Congenital and Acquired Obstructive Disorders
    1. CF
    2. Asthma
    3. COPD
    4. Pulmonary Hypertension – causes and outcomes

*The distinction between Typical and Atypical pneumonia appears to be more historic than clinically valuable. For this reason, on our exam we will continue to call S. pneumoniae the most common form of ‘Typical’ pneumonia, but otherwise not use these terms.
