A 25-30 year old female from Central Africa presented to the emergency department with chief complaints of fever, productive cough, night sweats and weight loss in the last 2 months. She also had two episodes of hemoptysis. There was no peripheral lymphadenopathy on examination. Patient had no known tuberculosis contacts. Patient gave a history of volunteering and visiting hospitals on weekends in her country of origin. She did not have any history of high-risk behavior or sexually transmitted diseases. She recalled being tested for Human Immunodeificiency Virus (HIV) in the past few years and was found to be negative. Patient's total leukocyte count was within normal reference range for the days of stay in the hospital, with low lymphocytes (Table 1).

The patient is a 41 year old gentleman who presented with a 2 week history of right sided "sharp and stabbing" rib pain without history of trauma or injury. The patient stated he felt a "snap" with a burst of pain in the right costal area, followed by inability to walk and could not breathe secondary to pain. His weight and appetite were stable prior to the incident. A chest CT scan revealed expansion of the cortex and medullary cavity of the right posterior 6th rib and a fracture with associated lytic focus in the posterior right 9th rib. The CT scan was interpreted as "hyperplasia/dysplasia" of the right 6th posterior rib and a pathologic fracture of the 9th posterior rib.

A classroom/lab activity using the Paleobiology Database to produce and interpret diversity curves for various groups of important and popular extinct animals, such as trilobites, ammonites, and dinosaurs. Activity helps students appreciate ancient life, geological time, and the important of mass extinctions in shaping the history of life, and by extension the implications of current extinctions. Outcomes:
Research how extinct animals lived, what they looked like, when they lived, and when they went extinct. Observe the geological timescale, name three geological eras, and use them to understand geological time. Name five major mass extinctions and relate them to the eras in which they occurred. Use the Paleobiology Database to produce diversity curves for an important group of extinct animals. Interpret graphs of diversity curves to understand the importance of mass extinctions in the history of life. (Optional) Communicate results of study to peers in class. In the process, synthesize information on multiple extinct animal groups to better appreciate the importance of extinctions in earth history.

The patient is a thirteen year-old female with a history of asthma who presented to the emergency department with a three-week history of an enlarging right neck mass. When the mass was first noticed, it was small and felt to be lymphadenopathy. In the subsequent weeks, it rapidly enlarged and became more painful. She had no fever and no signs or symptoms of upper respiratory tract infection. There was no respiratory compromise or dysphagia. She reported no recent weight loss. Physical examination showed her to be afebrile with normal vital signs. There was a 4 x 3 cm mildly tender, firm mass at the anterior border of the right sternocleidomastoid muscle at the level of the hyoid bone. No stridor was appreciated.

The Civil War, from 1861 to 1865, is the centerpiece of our nation's story. It looms large, not merely because of its brutality and scope but because of its place in the course of American history. The seeds of war were planted long before 1861 and the conflict remains part of our national memory. Geography has helped shape this narrative. The physical landscape influenced economic differences between the regions, the desire to expand into new territories, the execution of the conflict both in the field and on the home front, and the ways in which our recollections have been shaped. Maps enable us to present the complex strands that, when woven together, provide a detailed account of the causes and conduct of the war. These visual images remain a salient aspect of our memory. Photographs, prints, diaries, songs and letters enhance our ability to tell this story, when our nation, as a Currier & Ives cartoon depicts, was about to be "Torn in Two." This exhibition tells the story of the American Civil War both nationally and locally in Boston, Massachusetts, through maps, documents, letters, and other primary sources. This exhibition was developed by the Norman B. Leventhal Map Center, a nonprofit organization established as a partnership between the Boston Public Library and philanthropist Norman Leventhal.

A 61-year-old female with a past medical history of chronic lymphocytic leukemia (CLL) for 10 years, presented to the emergency room (ER) with left upper quadrant pain and multiple ecchymoses. Her past medical history included treatment with Fludarabine (last dose more than one year ago), Rituximab and Cytoxan. Of note, she presented to the ER with a seizure 6 months previously. Studies revealed a left fronto-temporal lesion, which was resected and diagnosed as a meningioma. To prevent seizures, she was started on Dilantin. At a follow up visit in neurosurgery, CBC values indicated pancytopenia. Because this was thought to be related to Dilantin treatment, it was suspended and Levetiracetam was initiated, but there were no improvements in her counts.

A 72 year-old right handed woman was referred to the Emergency Room of our Department with drug-resistant headache and unstable gait that had begun 7 days earlier. Neurological examination showed psychomotor slowing, wide-based ataxic gait, left homonymous hemianopsia, left-sided spatial neglect and ideomotor apraxia which emerged while putting on her shoes. In her medical history she mentioned hypothyroidism treated with levothyroxine 100mg, moderate hypertension, well-managed with antihypertensive medication, and a 5-year history of systemic lupus erythematosus (SLE), treated with prednisone 25mg. The complete blood count was normal. Lymphocyte count was 0.82×109/L

Tribal nations and Indigenous communities throughout North America have always enjoyed games and athletic activities that provide entertainment, teach skills of physical and mental endurance, promote tribal values such as teamwork and fairness, and allow individuals and teams to challenge themselves in competition. These games and activities range from the simple hand (or“stick”) game that dates back thousands of years to the modern-day Indian Relay Races that oftendraw large crowds. Even in the pre-contact era there were some similarities in the games playedby tribes in a given region or even in completely different parts of the country, but there were also many variations in the rules, materials, and methods of play. In this lesson, students will learn how to play one version of the hand game and will hear about some of the variations in the playing materials and rules used by different tribes in Oregon. Students will learn to take cues from opponents to identify the hand that holds the chosen item.
