Development of a Point-of-Care Ultrasound Track for Internal Medicine Residents.

Background: Point-of-care ultrasound (POCUS) training has been increasing among internal medicine (IM) residency programs, but few programs can provide longitudinal training due to barriers such as lack of trained faculty.

Aim: Describe the development of a longitudinal POCUS track for IM residents using local and external resources, including a national POCUS certificate program.

Setting: University-based IM residency program affiliated with a public and veterans affairs hospital.

South Texas Residency Screening, Brief Intervention, and Referral to Treatment (SBIRT) Training: 12-Month Outcomes.

Background: Screening, brief intervention, and referral to treatment (SBIRT) is an efficacious and cost-effective skill set when implemented in primary care settings regarding hazardous alcohol use. This study assesses the impact of medical resident SBIRT training across 3 specialties and identifies predictors of change in trainee behavior, attitudes, and knowledge over 12 months.

Methods: This program's substance use SBIRT training was developed and tailored to fit diverse curricular objectives and settings across an array of medical residency programs in South Texas.

Pocket-size imaging device: effectiveness for ward-based transthoracic studies.

Aims: Pocket-size imaging devices (PSID) are now available; their potential role in a hospital environment has been investigated but still remains undefined.

Methods And Results: We evaluated the effectiveness of PSID in 92 patients referred for bedside transthoracic echocardiogram (TTE). Patients were included where there was a focused clinical question: quantification of left ventricular function (LVF); presence of regional wall motion abnormalities (RWMA); evidence of pericardial effusion, exclusion of significant valve pathology.

Asymmetric synthesis of bicyclo[4.3.1]decadienes and bicyclo[3.3.2]decadienes via [6 + 3] trimethylenemethane cycloaddition with tropones.

The cyanosubstituted trimethylenemethane donor undergoes palladium-catalyzed [6 + 3] cycloaddition with a variety of tropones to yield bicyclo[4.3.1]decadienes in excellent regio-, diastereo-, and enantioselectivity.

Primary varicella-zoster-induced rhabdomyolysis.

Acute rhabdomyolysis after uncomplicated, primary varicella-zoster infection is a rare condition that is sparsely reported in the literature. We report a case of acute rhabdomyolysis due to varicella-zoster infection and review the literature regarding the etiology, diagnosis, and management of this potentially life-threatening condition. Rapid recognition, along with appropriate treatment, should result in an excellent recovery without adverse sequelae.

Hansen's Disease.

Physicians in the United States may encounter Hansen's disease in immigrants and areas such as Texas, Louisiana, Hawaii, and California. Exposure to infected armadillos may be one means of acquiring the disease. The Mycobacterium leprae bacillus has a predilection for nerves and skin in the cooler areas of the body.

Abnormal uterine bleeding.

Concerns about abnormal menstrual bleeding are a common reason for women to consult a primary care physician. The first step in the evaluation is to determine the patient's ovulatory status. Women with heavy bleeding but normal ovulatory cycles should be evaluated for coagulopathies, structural lesions, and hypothyroidism.

Suppression of specific IgM, IgA and IgG responses in mice treated with anti-delta from birth.

In contrast to previous studies, we report that heterologous anti-delta antibodies can act as a powerful multi-class humoral immunosuppressant. Primary direct plaque-forming cell (IgM) responses of BALB/c mice injected from birth with a rabbit anti-delta antiserum were reduced to 3% of control levels against a T-dependent antigen (sheep red blood cells), and to 2% against a T-independent antigen (dextran); IgA responses against 2 intraduodenal injections of cholera toxin were reduced to 7% of control levels. Other secondary immune responses of anti-delta-suppressed mice were suppressed to a lesser degree.

Theoretical and experimental studies of energy exchange from jackrabbit ears and cylindrically shaped appendages.

Convection properties of jackrabbit ears were examined in a wind tunnel and in the field in an attempt to study the possible thermal role of the large ears. This work was part of a study on energy exchange of appendages. Cylindrical copper models of various shapes, aluminum castings of domestic and jackrabbit ears, and an amputated jackrabbit ear were studied in a wind tunnel (a) to define the range for convective heat loss for appendages of various shapes, and (b) to study the effect on convection of model shape and orientation to the wind.
