ABSTRACT
In July 2017, fever and sepsis developed in 3 recipients of solid organs (1 heart and 2 kidneys) from a common donor in the United States; 1 of the kidney recipients died. Tularemia was suspected only after blood cultures from the surviving kidney recipient grew Francisella species. The organ donor, a middle-aged man from the southwestern United States, had been hospitalized for acute alcohol withdrawal syndrome, pneumonia, and multiorgan failure. F. tularensis subsp. tularensis (clade A2) was cultured from archived spleen tissue from the donor and blood from both kidney recipients. Whole-genome multilocus sequence typing indicated that the isolated strains were indistinguishable. The heart recipient remained seronegative with negative blood cultures but had been receiving antimicrobial drugs for a medical device infection before transplant. Two lagomorph carcasses collected near the donor's residence were positive by PCR for F. tularensis subsp. tularensis (clade A2). This investigation documents F. tularensis transmission by solid organ transplantation.

BACKGROUND: This is a prospective study to define the volume of pleural fluid adequate for maximal yield of cytologic analysis of pleural fluid. METHODS: Patients undergoing diagnostic thoracentesis with malignancy in the differential diagnosis were enrolled in the study. The first 50 mL of pleural fluid were put in a specimen cup, and subsequent fluid was collected in a drainage bag. Both samples were sent for cytologic evaluation. The cytologist was blinded as to which specimen was being evaluated. RESULTS: Forty-four patients (21 men, 23 women; mean [+/- SD] age, 46 +/- 11.1 years) were enrolled in the study. The average volume of the "large-volume" specimen was 890 +/- 375 mL (range, 250 to 1,800). Although malignant pleural involvement had never been documented for any patients, 31 patients had received a diagnosis of malignancy prior to undergoing thoracentesis. Cytologic tests were positive for malignancy in 23 of the 44 patients (55%). In the group of patients with an established history of cancer, pleural fluid was positive for malignant cells in 19 of 33 samples (58%). In all 23 patients with malignant pleural effusion, both the 50-mL specimen and the large-volume specimen were cytologically identical. In all 21 patients with negative pleural cytology findings, there was again 100% concordance between the 50-mL samples and the larger samples. The minimum adequate pleural fluid volume for cytologic diagnosis has been a matter of debate. The strongest data to date came from a retrospective study in 2002. CONCLUSIONS: Our prospective study now unequivocally supports the concept that the submission of > 50 mL of pleural fluid for cytologic analysis does not increase diagnostic yield.

APACHE (Acute Physiology and Chronic Health Evaluation) mortality predictions and other outcomes are reported after the initiation of a telemedicine intensivist staffing program to monitor the intensive care unit patients of a rural health system. Mortality, length of ICU stay, and length of hospital stay were significantly less than predicted. Length of stay was identical to one year previously in the largest hospital reported, but the case mix index of severity had increased. More severely ill patients were being treated without increase in length of stay.

OBJECTIVE: To discuss the rare association between primary hyperparathyroidism and chronic urticaria. METHODS: A case report with clinical and laboratory details is presented, and the pertinent literature is reviewed. RESULTS: A 29-year-old patient with chronic urticaria for more than 2 years, which was partially responsive to medical treatment, was found to have primary hyperparathyroidism. After parathyroidectomy, the urticaria resolved, and it has not recurred during a 1-year follow-up period. CONCLUSION: Primary hyperparathyroidism can be a rare cause of chronic urticaria.
