Until recently confusion has existed concerning the clinical features and surgical treatment of gastroschisis and omphalocele. Since 1971 75 infants with these abdominal wall defects have been treated at our institution. Significant differences (p equal to 0.001 in all instances) were noted between the two diseases. Gastroschisis occurred twice as often as omphalocele and is increasing in frequency. Prematurity was commonly seen with gastroschisis (65%). While the overall incidence of malformations associated with gastroschisis was low (23%), the vast majority of the additional malformations were jejunoileal or colonic atresias. The mortality rate was 12.7% among gastroschisis patients, with only one death attributable to prematurity. All other deaths were preventable, indicating that even lower mortality rates are feasible. Omphalocele was associated with a 23% incidence of premature birth but associated anomalies were present in 66% of the patients. Major cardiac (52%) and chromosomal defects (40%) predominated. In addition, 17% of omphalocele patients had either Cantrell's pentalogy or cloacal/bladder exstrophy. The mortality rate in omphalocele (34%) was nearly three times that of gastroschisis. Nine of ten patients who died from omphalocele died either from major cardiac or chromosomal disease. However, in patients without cardiac or chromosomal defects the survival rate was 94%.

The use of anthrax as a weapon of biological terrorism has moved from theory to reality in recent weeks. Following processing of a letter containing anthrax spores that had been mailed to a US senator, 5 cases of inhalational anthrax have occurred among postal workers employed at a major postal facility in Washington, DC. This report details the clinical presentation, diagnostic workup, and initial therapy of 2 of these patients. The clinical course is in some ways different from what has been described as the classic pattern for inhalational anthrax. One patient developed low-grade fever, chills, cough, and malaise 3 days prior to admission, and then progressive dyspnea and cough productive of blood-tinged sputum on the day of admission. The other patient developed progressively worsening headache of 3 days' duration, along with nausea, chills, and night sweats, but no respiratory symptoms, on the day of admission. Both patients had abnormal findings on chest radiographs. Non-contrast-enhanced computed tomography of the chest showing mediastinal adenopathy led to a presumptive diagnosis of inhalational anthrax in both cases. The diagnoses were confirmed by blood cultures and polymerase chain reaction testing. Treatment with antibiotics, including intravenous ciprofloxacin, rifampin, and clindamycin, and supportive therapy appears to have slowed the progression of inhalational anthrax and has resulted to date in survival.

this report was posted as an MMWR Early Release on the MMWR website (https://www.cdc.gov/mmwr).The National Football League (NFL) and the NFL Players Association (NFLPA) began the 2020 football season in July, implementing extensive mitigation and surveillance measures in facilities and during travel and gameplay. Mitigation protocols* were evaluated and modified based on data from routine reverse transcription-polymerase chain reaction (RT-PCR) tests for SARS-CoV-2, the virus that causes coronavirus 2019 (COVID-19); proximity tracking devices; and detailed interviews. Midseason, transmission was observed in persons who had cumulative interactions of <15 minutes' duration, leading to a revised definition of highrisk contacts that required consideration of mask use, setting and room ventilation in addition to proximity and duration of interaction. The NFL also developed an intensive protocol that imposed stricter infection prevention precautions when a case was identified at an NFL club. The intensive protocol effectively prevented the occurrence of high-risk interactions, with no high-risk contacts identified for 71% of traced cases at clubs under the intensive protocol. The incorporation of the nature and location of the interaction, including mask use, indoor versus outdoor setting, and ventilation, in addition to proximity and duration, likely improved identification of exposed persons at higher risk for SARS-CoV-2 infection. Quarantine of these persons, along with testing and intensive protocols, can reduce spread of infection.The NFL consists of 32 member clubs based in 24 states. The NFL-NFLPA implemented a standard COVID-19 mitigation protocol in July that included mandatory masking; physical distancing; frequent handwashing; facility disinfection; restricted facility access; and regular, frequent testing of players and staff members (1). Contact tracing was performed by trained staff members and supported by KINEXON wearable proximity devices (https://kinexon.com) that were required to be worn by players and personnel when in club environments (2). Device recordings captured consecutive and cumulative minutes/seconds of interactions among persons within 1.8 meters (6 feet) of one another. When testing identified a new COVID-19 case, trained staff members conducted interviews to identify contacts *
