Iron Stores in Low and Normal Birth Weight Infants at Birth and in Early Infancy

Serum ferritin levels of low birth weight (LBW; BW?<?2,500 g) and normal birth weight (NBW; BW?≥?2,500 g) infants were evaluated at birth and at 3 mo using electrochemiluminescence immunoassay. At birth, levels were 318.6 (31.0–829.5) ng/mL in LBW (n?=?217) and 366.2 (122.4–858.5) ng/mL in NBW infants (n?=?116; p?<?0.01), with 1.4 % of LBW and none of the NBW infants having levels <12 ng/mL (p?=?0.20). At follow up, levels were 66.9 (4.5–567.7) ng/mL in LBW (n?=?126) and 126.2 (6.8–553.7) ng/mL in NBW infants (n?=?76; p?=?0.27), with 11.9 % of LBW and 11.8 % of NBW infants having levels <12 ng/mL (p?=?0.80).     

Outcomes of transplantation using organs from a donor infected with Klebsiella pneumoniae carbapenemase (KPC)‐producing K. pneumoniae

Transmission of pathogens from donor to recipient is a potential complication of organ transplantation. Herein, we describe the clinical course and outcomes of 4 transplant recipients who received tissues from a donor with multi‐organ infection with Klebsiella pneumoniae carbapenemase (KPC)‐producing K. pneumoniae. Recipient 1 underwent simultaneous liver and kidney transplantation for alpha‐1 antitrypsin deficiency and alcohol‐related cirrhosis, and acute tubular necrosis, respectively. Soon after transplantation, he developed an infected hematoma and peritonitis due to KPC‐producing K. pneumoniae despite receiving tigecycline prophylaxis. He was treated with a prolonged course of tigecycline, amikacin, and meropenem, in conjunction with surgical evacuation and percutaneous drainage of the infected fluid collections. Recipient 2 underwent living‐donor liver transplantation for cholangiocarcinoma and primary sclerosing cholangitis using vein graft from the donor infected with KPC‐producing K. pneumoniae. Culture of the preservation fluid containing the vein graft was positive for KPC‐producing K. pneumoniae. The patient received preemptive amikacin and tigecycline, and he did not develop any infection (as evidenced by negative surveillance blood cultures). The isolates from the donor and Recipients 1 and 2 were indistinguishable by pulsed‐field gel electrophoresis. Recipients 3 and 4 underwent kidney and heart transplantation, respectively; both patients received perioperative tigecycline prophylaxis and did not develop infections due to KPC‐producing K. pneumoniae. All transplant recipients had good short‐term outcomes. These cases highlight the importance of inter‐institutional communication and collaboration to ensure the successful management of recipients of organs from donors infected with multidrug‐resistant organisms.     

Anaesthetic complications in plastic surgery

Anaesthesia related complications in plastic surgeries are fortunately rare, but potentially catastrophic. Maintaining patient safety in the operating room is a major concern of anaesthesiologists, surgeons, hospitals and surgical facilities. Circumventing preventable complications is essential and pressure to avoid these complications in cosmetic surgery is increasing. Key aspects of patient safety in the operating room are outlined, including patient positioning, airway management and issues related to some specific conditions, essential for minimizing post-operative morbidity. Risks associated with extremes of age in the plastic surgery population, may be minimised by a better understanding of the physiologic changes as well as the pre-operative and post-operative considerations in caring for this special group of patients. An understanding of the anaesthesiologist''s concerns during paediatric plastic surgical procedures can facilitate the coordination of efforts between the multiple services involved in the care of these children. Finally, the reader will have a better understanding of the perioperative care of unique populations including the morbidly obese and the elderly. Attention to detail in these aspects of patient safety can help avoid unnecessary complication and significantly improve the patients’ experience and surgical outcome.KEY WORDS: Anaesthesia, complications, plastic, surgery
