Tx: Inhaler, monitor, calm the athlete down, EMS? Inflammation of the coverings around brain & spinal cord Usually caused by a bacterial or viral infection • Viral: most common, usually not as serious Can cause prolonged fever & seizures • Bacterial: not as common, but very serious Can cause brain damage & death Typically seen in children, teens, and young adults Contagious – passed via coughing, sneezing, & close contact Sx: • • • • A stiff & painful neck, especially w/ neck flexion Fever Headache Seizures Causes: • Excessive loss of blood (can be seen w/ menstrual cycles) • Deficient intake of iron • Poor absorption of iron Sx: • Weakness/Feeling tired • Feeling grumpy • Headaches • Difficulty concentrating • Light-headedness • Difficulty breathing Physical findings or changes in behavior that occur after an episode of abnormal electrical activity in the brain Often used interchangeably w/ "convulsions" • Convulsions are uncontrollable body • shaking/contracting & relaxing of muscles There are many types of seizures…not all have convulsions Remain calm Cushion fall Clear area Loosen restrictive clothing Place soft cloth between teeth Allow patient to awaken normally Do not restrain patient during seizure Call 911 if: • • • • • • First seizure Lasts more than 2 to 5 min The person remains unconscious More then one seizure Caused by head injury or has diabetes Atypical seizure for them Due to rapid breathing, levels of carbon dioxide are low (compared to O2) in bloodstream Body responds to lower CO2 by constricting blood vessels in brain Sx: • • • • Lightheaded, headache Rapid heartbeat & RR Numbness or tingling in hands, feet, or mouth Shaking/seizures Tx: Slow respiratory rate • Breath in through nose & out through mouth • Inhale/exhale through one nostril w/ the other pinched and mouth closed • Breath into a paper or plastic bag Severe allergic reaction Sy: Chest tightness, difficulty breathing, dizziness Sx:Wheezing, swollen tongue/lips/throat, bluish skin, hives, nausea, vomiting, confusion Tx: Epi-pen, monitor, activate EMS Prevention: Know athletes’ Hx Stones may form in any part of UT, most occur in kidney Dissolved urine salts begin to solidify May increase in size & result in obstruction Intense radiating pain from kidney area to groin Tx: US waves, ureteroscopic removal, allow to pass on own UTI or Kidney Infection • Caused by bacteria Obstruction or ‘holding it’ paves way for infection due to stagnation of urine Sx: pain w/ urination, increased urgency & frequency, fever & chills possible Tx: antibiotics Inflammation of the appendix Not sure what it does & we can live without it Medical emergency - requires prompt surgery to remove the appendix Will eventually burst, or perforate, spilling infectious materials into abdominal cavity In U.S. – affects 1:15, usually between 10-30 y/o Sx: Pain in LR abdomen, fever, loss of appetite, nausea or vomiting Protrusion of any organ or tissue through the wall of the cavity that contains it Sports Hernia: “Athletic Pubalgia” Typically no lump felt on exam, will worsen if not properly treated Tx: PT, Surgery? Strangulated Hernia: • Blood supply to hernia is cut off, can lead to necrosis/gangrene (tissue death) Direct blow to left side Mono may enlarge the spleen, making contact sports extremely risky Profuse internal bleeding Early stage: pain in upper left quadrant, tenderness, bruising Life threatening stage: Pain in left neck/shoulder, faintness, dizziness, pale skin, rapid pulse, vomiting, low BP, SOB, rigid abdominal muscles Blow to flank/mid back Early stage: Pain at site, bruising Advanced stage: faintness, dizziness, increased HR, bloody or cloudy urine, vomiting, rigid back muscles, pale and cool skin, frequent and burning urination Diabetes Mellitus (DM): • Most common pancreatic disorder • Type I • Type II • Gestational 7th leading cause of death in U.S. in 2006 23.6 million children & adults in US (7.8%) • Diagnosed: 17.9 million people • Undiagnosed: 5.7 million people • Pre-diabetes: 57 million people • New Cases: 1.6 million adults each year 22% of all people <20 y/o have diabetes • Recent estimates put this closer to 1/3 About 2 million adolescents aged 12-19 are considered pre-diabetic 20+ y/o: • 6.6% of non-Hispanic whites • 7.5% of Asian Americans • 11.8% of non-Hispanic blacks • 10.4% of Hispanics Heart disease and stroke • 2 to 4 x’s higher risk than adults w/o diabetes.
