Multistate outbreak of Oranienburg infections linked to bulb onions imported from Mexico - United States, 2021.

In 2021, the U.S. Food and Drug Administration (FDA), the Centers for Disease Control and Prevention (CDC), and state and local health and regulatory partners investigated an outbreak of serovar Oranienburg infections linked to bulb onions from Mexico, resulting in 1040 illnesses and 260 hospitalizations across 39 states, the District of Columbia, and Puerto Rico.

A Multistate Outbreak of O157:H7 Infections Linked to Soy Nut Butter.

Background: In 2017, we conducted a multistate investigation to determine the source of an outbreak of Shiga toxin-producing (STEC) O157:H7 infections, which occurred primarily in children.

Methods: We defined a case as infection with an outbreak strain of STEC O157:H7 with illness onset between January 1, 2017, and April 30, 2017. Case patients were interviewed to identify common exposures.

Early results of surgery in 123 patients with pseudomyxoma peritonei from a perforated appendiceal neoplasm.

Purpose: Epithelial appendiceal tumors are uncommon but can present as an emergency simulating appendicitis, or unexpectedly at laparotomy, laparoscopy, or on cross-sectional imaging. Occult rupture with features of pseudomyxoma peritonei may be encountered. We report the operative findings, pathologic assessment, and early outcomes in 123 consecutive patients with a perforated appendiceal neoplasm presenting as pseudomyxoma peritonei.

Total mesorectal excision results in low local recurrence rates in lymph node-positive rectal cancer.

Purpose: Most series report lymph node involvement as the main predictor for local recurrence. The principal lymphatic drainage of the rectum is to nodes in the mesorectum and then nodes along the superior rectal and inferior mesenteric arteries. If total mesorectal excision provides adequate block dissection of the lymphatics of the rectum, good local control with low rates of local recurrence should be achieved even in node-positive disease.

Rectal cancer in the elderly: patients' perception of bowel control after restorative surgery.

Objective: The risk of incontinence is perceived as a relative contraindication to a sphincter-saving procedure in elderly patients with rectal cancer. To investigate this, we reviewed functional results one year after restorative surgery in patients older than aged 75 years.

Methods: A total of 186 patients older than aged 75 years were diagnosed with rectal cancer during the study period.
