Perineal body length and perineal lacerations during delivery in primigravid patients.
This study assessed the relation between perineal body length and the risk of perineal laceration extending into the anal sphincter during vaginal delivery in primigravid patients at an institution with a low utilization of episiotomy. This was a prospective study of primigravid patients in active labor. Primigravid women with singleton pregnancies who were in the first stage of labor at 37 weeks gestation or greater were recruited, and the admitting physician measured the length of the perineal body. ⋯ The perineal body length, duration of second stage of labor, type of delivery, and patient age were associated (P < 0.1) with third- and fourth-degree (severe) perineal lacerations in primigravid women using receiver-operator curve analysis. Using logistic regression, only the duration of second stage of labor and length of the perineal body were significant (P < 0.04) predictors of third- and fourth-degree lacerations, with odds ratios of 32 (1.3 to 807 as 95% CI) and 24 (1.3 to 456), respectively. Both a perineal body length of ≤3.5 cm and a duration of second stage of labor >99 minutes were associated with an increased risk of third- and fourth-degree lacerations in primigravid patients.

Factors associated with performance in an internal medicine clerkship.
The purpose of this retrospective study was to examine the relationship between demographic and educational variables and student performance on an internal medicine (IM) clerkship in order to target areas for educational intervention and potential early remediation. This study examined data associated with third-year medical student performance (N = 505) during the IM clerkship at Baylor Scott & White, Temple/Texas A&M Health Science Center College of Medicine from 2005 to 2011. Multiple regression analysis (N = 341) showed that a model containing the following variables was significantly associated with scores on the National Board of Medical Examiners (NBME) subject exam, accounting for 46.5% of the variance: Objective Structured Clinical Exam (OSCE), Medical College Admissions Test (MCAT), US Medical Licensing Exam (USMLE) Step 1, second-year grade point average (GPA), and clinical evaluation. ⋯ In conclusion, in contrast to previous studies in the field, we did not find a significant association between undergraduate GPA and NBME score. Our findings supply further evidence that the OSCE, typically believed to be a clinical performance exam, actually assesses a broader set of domains. Interest group membership did not confer any academic benefit to medical students in IM clerkships in our study.

Case ReportsB-cell lymphoma, thiamine deficiency, and lactic acidosis.
Type B lactic acidosis is found in the absence of tissue hypoperfusion, can be associated with malignancies, and can be caused by thiamine deficiency. We present a patient who presented with an abdominal mass that biopsy disclosed to be a diffuse large B-cell lymphoma. ⋯ The level prior to treatment was low. The case emphasizes a rare cause of lactic acidosis.

Case ReportsAn approach for safe conversion of an oral endotracheal tube to a nasal endotracheal tube.
We present an approach for safe management of a patient with an oral endotracheal tube who required conversion to a nasal endotracheal tube. A 35-year-old man presented for mandibular fracture repair after multiple injuries sustained in a motor vehicle accident. The patient already had an oral endotracheal tube, and the surgical team requested a nasal endotracheal tube to facilitate surgical exposure and postoperative airway management in anticipation of a wired jaw. ⋯ A tracheal tube introducer was inserted through the oral endotracheal tube, and the oral endotracheal tube was then withdrawn approximately 5 cm. The nasal endotracheal tube was advanced through the vocal cords alongside the tracheal tube introducer. The nasal endotracheal tube cuff was then inflated and the tracheal tube introducer was withdrawn.

Case ReportsEpipericardial fat necrosis as a cause of acute chest pain.
Acute chest pain is one of the most common reasons for presentation to the emergency department. Although most etiologies of chest pain are easy to clinically ascertain with routine history, physical, and laboratory examinations, we present an important benign cause of acute chest pain that may mimic acute coronary syndrome.
