Clerkship directors' perceptions of the impact of HCFA documentation guidelines.

PURPOSE: Chart notes are used to support billing codes under the evaluation and management guidelines of the Health Care Financing Administration (HCFA), in addition to serving as a record of the visit. To better understand the effect of the HCFA documentation guidelines, the authors collected data on how the guidelines affect participation by university- and community-based faculty in clinical education programs. METHOD: In 2000, the authors sent six copies of their questionnaire to the associate deans of the 125 U.S. medical schools and requested they distribute them to all core clerkship directors. The questionnaire consisted of multiple-choice and short-answer questions regarding documentation of medical visits, participation of community-based faculty, understanding of HCFA documentation guidelines, and effects on education programs. RESULTS: The response rate was about 50%. Most of the 379 clerkship directors who responded (77%) stated they were aware the HCFA documentation guidelines include specifications regarding the role medical students can play and documentation of medical visits, and 64% indicated they were concerned the guidelines would affect their educational programs. Concerns included the loss of student independence and active participation in the patient care environment (37), time constraints and the changing balance between education and service (16), loss of faculty and decreased morale (11), and decreased quality of care for patients (7). CONCLUSION: Leaders of medical education must work to modify these guidelines to protect the quality of patients' care, while maximizing students' educational opportunity and participation.     

Recurrent carotid stenosis. Incidence and management

The actual incidence of recurrent carotid occlusive disease is not known. From January 1974 through December 1984, fifty-four patients underwent at least one second carotid endarterectomy or reconstructive procedure at St. Thomas Hospital in Nashville. Five patients required a third carotid operation. This retrospective study examines case reports, risk factors, patient presentation, interval of recurrence, and pathology involved. Surgical techniques and results are described. Complications occurred in six patients undergoing a total of 66 operations for an overall incidence of 9 per cent. Thrombosis was minimized by the use of antiplatelet drugs. Follow-up of patients ranged from one to 84 months. Four main causes for restenosis are discussed.     

Prelinguistic predictors of language outcome at 3 years of age.

PURPOSE: The purpose of this study was to examine the predictive validity of a collection of prelinguistic skills measured longitudinally in the 2nd year of life to language outcome in the 3rd year in children with typical language development. METHOD: A collection of prelinguistic skills was assessed in 160 children early (M = 14.31 months; SD = 1.36) and late (M = 19.76 months; SD = 1.16) in their 2nd year by using the Communication and Symbolic Behavior Scales Developmental Profile Behavior Sample (A. Wetherby & B. Prizant, 2002). The relation between the prelinguistic skills and the receptive and expressive language near the 3rd birthday was examined. RESULTS: Significant correlations were observed between many prelinguistic skills and language outcome. Regression analyses indicated that comprehension both early and late contributed unique variance to receptive and expressive language outcome. In addition, early in the 2nd year, inventory of conventional gestures contributed uniquely to receptive language outcome, and acts for joint attention contributed uniquely to expressive outcome. Late in the 2nd year, inventory of consonants contributed uniquely to expressive outcome. CONCLUSIONS: The findings demonstrate continuity between prelinguistic and linguistic skills and how individual differences in a number of prelinguistic skills contribute collectively and uniquely to language outcome in typically developing children.     

Ensuring data quality in a multicenter clinical trial: remote site data entry, central coordination and feedback

In an ongoing multicenter clinical trial, "Treatment Strategies in Schizophrenia," the five participating sites have the capacity to perform a variety of tasks or study functions independently. These tasks include (a) verification of diagnostic eligibility through the use of computerized decision algorithms; (b) assignment of patients to treatment based on prognostic indicators using a computerized randomization algorithm; (c) entry of data into a microcomputer using a clinical trial data management system that performs simple range and missing data item checks; and (d) regular transfer of all data to the central coordinating team. The clinical trial data management system employed allows for both independent site functioning and assurance of consistency across sites. The integration of a variety of software outside the main data management system provides the central coordinators with the tools to monitor critical data as it is collected, as well as the capacity to assess the flow, quality, and uniformity of the ongoing trial.     

Primary cardiac neoplasms. Early and late results of surgical treatment in 42 patients

Forty-two patients underwent resection of primary cardiac neoplasms at Stanford University Medical Center and the Palo Alto Veterans Administration Medical Center between 1961 and 1986. A total of 27 atrial myxomas, seven benign nonmyxomatous tumors, and eight malignant tumors were resected. The mean age was 47 years (range 8 to 79) in 27 female and 15 male patients. The clinical presentations included congestive heart failure in 24 patients, palpitations in nine, neurologic symptoms in six, recurrent cardiac tamponade in three, vasculitis in two, and chest pain in two. Thirty-one of 34 benign lesions were completely resected, although one patient required cardiac transplantation to resect completely an "inoperable" benign tumor. All gross tumor was resected in four of eight patients with malignant lesions. All patients survived operation, but three with malignant disease died within 30 days. Late outcome was known for 41 of 42 (98%) patients. Total follow-up for the series was 200.1 patient-years, for an average of 4.7 years (range 1 month to 18 years). Excellent early and late results were obtained in patients with benign lesions, as there was no known tumor recurrence even if resection was incomplete. Effective palliation and local control of disease is possible with extensive resection of malignant primary tumors, but more effective adjuvant therapy will be necessary to improve long-term prognosis.     

Prostaglandins and cell-mediated immunity. The role of prostaglandin E1 in the induction of host-versus-graft and graft-versus-host reactions in mice

Based on studies in lymphocyte cultures it has been suggested that endogenous prostaglandins (PG), especially those of the E series (PGE), suppress cell-mediated immune reactions during their induction phase. We have tested this theory in experimental animals using local host-versus-graft (HVG) and graft-versus-host (GVH) reactions in mice. These reactions were suppressed in a dose-dependent manner by treatment of the animals with PGE1. If, however, endogenous PGE was neutralized through treatment of the animals with immune sera directed against PGE (APSE1) then inhibition of the development of HVG and GVH reactions was seen. This inhibition could be abrogated in "add back" experiments by treatment of the animals with PGE1. We suggest that the action of PGE1 during the induction phase of CMI responses is governed by a bell-shaped dose-response curve with a response-enhancing effect at low PGE1 and a suppressive effect at high PGE1 concentrations. APSE1 has proved to be very effective in inhibiting responses, and thus treatment with anti-PG antibodies may not only represent a valuable tool for the study of the role of PG in immunoregulation, but may become useful in therapeutic interventions with the immune system--e.g., after bone marrow transplantation.     

Anger Dimensions and Mental Health Following a Disaster: Distribution and Implications After a Major Bushfire

Anger is an important dimension of affect and a prominent feature of posttraumatic mental health, but it is commonly overlooked in postdisaster settings. We aimed to examine the distribution and implications of significant anger problems in the aftermath of a natural disaster, via analyses of Beyond Bushfires survey data from 736 residents of rural communities 5 years after the 2009 Black Saturday bushfires in Victoria, Australia. Assessments included the five‐item Dimensions of Anger Reaction (DAR‐5) scale along with measures of PTSD, depression, and significant mental illness, and indicators of life satisfaction, suicidality, hostile aggressive behavior, and violence exposure. The results indicated that approximately 10% of respondents from areas highly affected by the bushfires scored above the provisional cutoff criteria for significant anger problems on the DAR‐5, which was a more than 3‐fold increase, OR = 3.26, relative to respondents from areas of low‐to‐moderate bushfire impact. The rates were higher among women, younger participants, and those who were unemployed, and co‐occurred commonly, although not exclusively, with other postdisaster mental health problems. Anger problems were also associated with lower life satisfaction, β = ?.31, an 8‐fold increase in suicidal ideation, OR = 8.68, and a nearly 13‐fold increase in hostile aggressive behavior, OR = 12.98. There were associations with anger problems and violence exposure, which were reduced when controlling for covariates, including probable PTSD. The findings provide evidence indicating that anger is a significant issue for postdisaster mental health and should be considered routinely alongside other posttraumatic mental health issues.     

The Cellular Organization of the Mammary Gland: Insights From Microscopy

Despite rapid advances in our knowledge of the cellular heterogeneity and molecular regulation of the mammary gland, how these relate to 3D cellular organization remains unclear. In addition to hormonal regulation, mammary gland development and function is directed by para- and juxtacrine signaling among diverse cell-types, particularly the immune and mesenchymal populations. Precise mapping of the cellular landscape of the breast will help to decipher this complex coordination. Imaging of thin tissue sections has provided foundational information about cell positioning in the mammary gland and now technological advances in tissue clearing and subcellular-resolution 3D imaging are painting a more complete picture. In particular, confocal, light-sheet and multiphoton microscopy applied to intact tissue can fully capture cell morphology, position and interactions, and have the power to identify spatially rare events. This review will summarize our current understanding of mammary gland cellular organization as revealed by microscopy. We focus on the mouse mammary gland and cover a broad range of immune and stromal cell types at major developmental stages and give insights into important tissue niches and cellular interactions.

     

Flexor Tenosynovectomy for Recurrent Carpal Tunnel Syndrome: A Retrospective Case Series of 108 Hands

Background: The etiology of recurrent carpal tunnel syndrome (CTS) is unclear, and outcomes following secondary surgery in this demographic have been poorer than primary surgery. Fibrosis and hypertrophy have been identified in the flexor tenosynovium in these patients. The authors use flexor tenosynovectomy (FTS) for recurrent CTS after primary carpal tunnel release and present a review of these patients. Methods: A retrospective chart review was performed of 108 cases of FTS for recurrent CTS from 1995 to 2015 by 4 attending surgeons at one institution. Demographic information, symptoms, and outcomes were among the data recorded. A phone survey was conducted on available patients where the shortened version of the Disabilities of the Arm, Shoulder and Hand Questionnaire (QuickDASH) and satisfaction were assessed. Results: Average office follow-up was 12 months. Average age was 57.5 years. A total of 104 (96%) reported symptom improvement and 48 (44%) reported complete symptom resolution. Forty patients were available for long-term follow-up at an average 6.75 years postoperatively via phone interview. Average QuickDASH score was 31.2 in these patients. Thirty-six (90%) of 40 patients were initially satisfied at last office visit, and 31 (78%) of 40 were satisfied at average 6.9 years, a maintenance of satisfaction of 86%. Satisfied patients were older (58 years) than unsatisfied patients (51 years). Conclusion: Both long-term satisfaction and QuickDASH scores in our cohort are consistent with or better than published results from nerve-shielding procedures. The authors believe a decrease in both carpal tunnel volume and potential adhesions of fibrotic or inflammatory synovium contributes to the benefits of this procedure. This remains our procedure of choice for recurrent CTS.
