1A 19-year-old male took to his bed early one Friday evening, complaining of a flu-like illness and headache. He was previously healthy and had received all age-appropriate vaccinations, including a seasonal influenza vaccine and 2 doses of the quadrivalent meningococcal conjugate ACYW 135 vaccine at ages 12 and 19 years. He lived with his parents and a 14-year-old sister. The next morning his mother found him unresponsive with a widespread rash. He was taken to the ED. Physical examination revealed unresponsive patient with signs of meningeal irritation, pinpoint red and dark purple macules that did no blanch with pressure were noted on hid feet and lower legs. Vital signs: T-39,5°C, BP 120/70 mm Hg, pulse 120 /min, RR 32/min, O2 90 % on room air. A lumbar puncture was done after CT scan. The results of the CSF examination and Gram stain: appearance - turbid, cells - 800.106/l, neutrophils, protein – 0,75g/l, glucose – 0,5 mmol/l (blood glucose – 7,0 mmol/l) , Gram stain – no bacteria seen

41-year-old male was admitted to the hospital in December because of fever and dehydration. His parents reported that he had a 1-day history of fiver, diarrhea, intractable emesis and decreased urine output. On admission he was somnolent, his vital signs revealed T 39,5°C, pulse 126 beats/min and RR 32 breaths/min. His general PE was remarkable for hyperactive bowel sounds and decreased turgor. Laboratory test showed WBC 14 299.109/l, with 80% PMNs, urinalysis was significant for a high specific gravidity and ketones. Stool, blood, and urine samples were sent for bacterial cultures. The patient was given intravenous normal saline and had nothing by mouth. Over the next 48 hours his emesis abated. All cultures for bacterial pathogens gave negative results, but a rapid viral test from the stool was positive. Once he was rehydrated and was tolerating oral feeding he was discharged home

28The patient was a female in her late 80s with pulmonary hypertension requiring chronic O2 by nasal cannula. She had a hospital admission 1 mo previously for right middle lobe pneumonia. She was given a 14-day course levofloxacin and discharged to a skilled nursing home. Three weeks later she had the onset of loose, watery stools, which increased in frequency to >10 times/day, diffuse abdominal pain, vomiting, weakness and later was unable to walk. Her family and social history was significant only for her having recently moved to a nursing home. On readmission, she had 2,5 kg weight loss since her prior admission. She continued to have shortness of breath but no cough. Vital signs - pulse 120 /min, RR 24/min, and BP 82.45 mm Hg. On examination her abdomen was soft, diffusely tender and mildly distended with no rebound or guarding, with decreased bowel sounds. Otherwise her PE was consistent with her underlying disease. Laboratory data were significant for WBC 28 00.109/l. Her abdominal XR showed grossly dilated loops of bowels. Abdominal CT revealed colonic wall thickening consistent with pancolitis. Over the next 4 hospital days her WBC progressively increased from 29 000.109/l to 127 000.109/l. She had increased abdominal girth and decreased bowel sounds. She was judged to be a poor surgical risk. On the fourth hospital day the patient expired.

Three weeks later she had the onset of loose, watery stools, which increased in frequency to >10 times/day, diffuse abdominal pain, vomiting, weakness and later was unable to walk. Her family and social history was significant only for her having recently moved to a nursing home. On readmission, she had 2,5 kg weight loss since her prior admission. She continued to have shortness of breath but no cough. Vital signs - pulse 120 /min, RR 24/min, and BP 82.45 mm Hg. On examination her abdomen was soft, diffusely tender and mildly distended with no rebound or guarding, with decreased bowel sounds. Otherwise her PE was consistent with her underlying disease. Laboratory data were significant for WBC 28 00.109/l. Her abdominal XR showed grossly dilated loops of bowels. Abdominal CT revealed colonic wall thickening consistent with pancolitis. Over the next 4 hospital days her WBC progressively increased from 29 000.109/l to 127 000.109/l. She had increased abdominal girth and decreased bowel sounds. She was judged to be a poor surgical risk. On the fourth hospital day the patient expired.
