Human Granulocytic Ehrlichiosis Complicating Early Pregnancy
Background. The goal of this case is to review the zoonotic infection, human granulocytic ehrlichiosis, presenting with pyrexia. Case. A 22-year-old multigravid female presented to the emergency department with a painful skin rash, high fever, and severe myalgias. The patient underwent a diagnostic evaluation for zoonotic infections due to her geographical and seasonal risk factors. Treatment of human granulocytic ehrlichiosis was successful though the patient spontaneously aborted presumably due to the severity of the acute illness. Conclusion. Treatment of human granulocytic ehrlichiosis in pregnancy presents unique challenges. Management of pyrexia during pregnancy is limited to external cooling in the setting of thrombocytopenia and elevated aminotransferases. Extensive counseling regarding teratogenic potential of medications allows the patient to weigh the pros and cons of treatment

suture materials.
Study Design—Chromic catgut, polyglactin 910, silk, and polydioxanone sutures were tied in
the two types of knot configurations. For all sutures, a 0-gauge United States Pharmacopeia suture
was used. Knots were tied by a single investigator (JB). Suture was soaked in 0.9 % sodium
chloride for 60 seconds and subsequently transferred to a tensiometer where the tails were cut to 3
mm length. We compared the knots, measuring knot strength using a tensiometer until the sutures
broke or untied.
Results—A total of 119 knots were tied. We found no difference in mean tension at failure
between a surgeon’s knot (79.7 Newtons) and a flat square knot (82.9 Newtons). Using a Chisquare
test, we did not find a statistically significant difference in the likelihood of knots coming
untied between surgeon’s knots (29%) and flat square knots (38%).
Conclusions—Under laboratory conditions, surgeon’s knots and flat square knots did not differ
in tension at failure or likelihood of untying
Hysterectomy Volume Among Recent Obstetrics and Gynecology Residency Graduates
OBJECTIVE: Although guidelines recommend hysterectomy be performed vaginally whenever possible, recent trainees have decreased exposure to vaginal hysterectomy given the availability of laparoscopic hysterectomy, nonsurgical management, and falling volume nationwide. We sought to estimate hysterectomy volume in the 5 years after residency. Our secondary objective was to compare vaginal hysterectomy utilization between recent graduates and senior surgeons.
METHODS: Retrospective, statewide data from 2005 to 2014 was obtained from the Massachusetts Center for Health Information Analysis. All hysterectomies performed in Massachusetts, regardless of payer type, were included. Surgeon identifiers were cross-referenced to another data set with provider demographics. Hysterectomies performed in the first 5 years after graduation were compared with a group 21 to 25 years after residency.
RESULTS: Data from inpatient and outpatient databases revealed 87,846 hysterectomies performed by 1967 physicians, including 3146 simple hysterectomies by 192 recent graduates. Recent graduates chose abdominal hysterectomy (44.2%) most commonly, followed by laparoscopic (29.4%), vaginal (16.1%), and laparoscopically assisted vaginal (10.4%). Recent graduates performed a median of 3 to 4 hysterectomies in each of the first 5 years with no increase over time (P = 1). The median number of vaginal or laparoscopic hysterectomies was 0 in these 5 years (interquartile ranges, 0-1 and 0-2, respectively). Members of the senior cohort performed a median of 8 to 9 hysterectomies annually, completing them vaginally more often (24.7% vs 16.1%, P \u3c 0.01). When controlling for patient age and hysterectomy indication, this effect dissipated.
CONCLUSIONS: Recent graduates perform 3 to 4 (interquartile range, 1-7) hysterectomies annually, predominantly by laparotomy. Although senior surgeons perform vaginal hysterectomy more often, this is explained by patient characteristics

Effect of the COVID-19 Pandemic on Otolaryngology Trainee Surgical Case Numbers: A Multi-institutional Review.
OBJECTIVE: To determine the effect of the initiation of COVID-19-related restrictions on the volume of surgical cases performed by otolaryngology trainees. STUDY DESIGN: Multi-institutional retrospective analysis of resident surgical case logs. SETTING: Accredited residency training programs in otolaryngology head and neck surgery. METHODS: Resident surgical case logs were combined from 6 residency training programs from different regions of the United States. Case volumes were compared between the calendar year before March 1, 2020, and the year afterward. Subgroup analyses were performed for the type of hospital (university, pediatric, veteran, county) and the key index cases by subspecialty. RESULTS: All 6 participating residency programs had a decrease in resident operative case volume. Surgical volume decreased from a mean of 6014 to 4161 (P < .05). There were decreases observed in key index cases in every subspecialty (P < .01), without statistical differences seen among subspecialties. There were decreases observed in every hospital type (university, pediatric, veteran, county) without statistical differences among types. Postgraduate year 5 residents were the most affected by volume reductions (51.6%), and postgraduate year 3 residents were the least affected (1.4%). CONCLUSION: In the year following initiation of COVID-19-related restrictions, there was a significant decrease in trainee surgical case volumes within residencies for otolaryngology-head and neck surgery. There were no statistical differences in the volume decreases seen at different institutions, among hospital types, or within various subspecialties
