Comparison of Factors Identified by Patients and Physicians Associated with Hospital Readmission (COMPARE2).

OBJECTIVE: Factors contributing to hospital readmission have rarely been sought from the patient perspective. Furthermore, it is unclear how patients and physicians compare in identifying factors contributing to readmission. The objective of the study was to identify and compare factors contributing to hospital readmission identified by patients and physicians by surveying participants upon hospital readmission to a teaching medicine service. METHODS: Patients 18 years and older who were discharged and readmitted to the same service within 30 days and the physicians caring for these patients were surveyed to identify factors contributing to readmission. Secondary outcomes included comparing responses between groups and determining level of agreement. Patients could be surveyed multiple times on subsequent readmissions; physicians could be surveyed for multiple patients. RESULTS: A total of 131 patients and 37 physicians were consented. The mean patient age was 60.1 years (standard deviation 16.8 years) and 55.6% were female; 56.4% were white, and 42.1% were black/African American. In total, 179 patient surveys identified "multiple medical problems" (48.6%), "trouble completing daily activities" (45.8%), and "discharged too soon" (43.6%) most frequently as contributing factors; 231 physician surveys identified "multiple medical problems" (45.0%) and "medical condition too difficult to care for at home" (35.6%) most frequently as contributing factors. Paired survey results were available for 135 readmissions and showed fair agreement for only 1 factor but no agreement for 5 factors. CONCLUSIONS: Patients identified previously unknown factors contributing to readmission. Little agreement existed between patients and physicians. Additional research is needed to determine how best to address patient-identified factors contributing to readmission.

Paraneoplastic cerebellar syndromes associated with antibodies against Purkinje cells.

The paraneoplastic cerebellar syndrome presents as severe neuroimmunological disease associated with malignancies. Antibodies against antigens expressed by tumor cells cross-react with proteins of cerebellar Purkinje cells leading to neuroinflammation and neuronal loss. These antineuronal antibodies are preferentially investigated by serological analyses while examination of the cerebrospinal fluid is only performed infrequently. We retrospectively investigated 12 patients with antineuronal antibodies against Purkinje cells with a special focus on cerebrospinal fluid. Our results confirm a subacute disease with a severe cerebellar syndrome in 10 female patients due to anti-Yo antibodies associated mostly with gynecological malignancies. While standard cerebrospinal fluid parameters infrequently revealed pathological results, all patients presented oligoclonal bands indicating intrathecal IgG synthesis. Analyses of anti-Yo antibodies in cerebrospinal fluid by calculating the antibody specific index revealed intrathecal synthesis of anti-Yo antibodies in these patients. In analogy to anti-Yo syndrome, an intrathecal production of anti-Tr antibodies in one patient who presented with a paraneoplastic cerebellar syndrome was detected. In an additional patient, anti-Purkinje cell antibodies of unknown origin in the cerebrospinal fluid but not in serum were determined suggesting an isolated immune reaction within the central nervous system (CNS) and underlining the importance of investigating the cerebrospinal fluid. In conclusion, patients with a cerebellar syndrome display a distinct immune reaction within the cerebrospinal fluid including intrathecal synthesis of disease-specific antibodies. We emphasize the importance of a thorough immunological work up including investigations of both serum and cerebrospinal fluid.

Intrathecal synthesis of anti-Hu antibodies distinguishes patients with paraneoplastic peripheral neuropathy and encephalitis.

BACKGROUND: Paraneoplastic syndromes are serious immune caused diseases of the peripheral and/or central nervous system associated with malignant neoplasm. Symptoms develop when antibodies against antigens expressed by tumor cells cross-react with neuronal proteins. Antineuronal antibodies are usually examined in patient's sera while examination of the cerebrospinal fluid (CSF) often fails. Furthermore, the few previous reports describing CSF data summarized different antineuronal antibodies and/or regarded patients with different neurological symptoms as one group. METHODS: We retrospectively evaluated data of 18 patients with paraneoplastic syndromes due to anti-Hu antibodies. The study aimed to differentiate patients with peripheral neuropathy and encephalitis by cerebrospinal fluid (CSF) parameters including anti-Hu antibody titers. RESULTS: Our results confirm previous observations that serum titers of anti-Hu antibodies and standard CSF values do not differ between patients with neuropathy and encephalitis. However, analysis of CSF anti-Hu titers and calculating the intrathecal synthesis helped to discriminate between both groups. CONCLUSION: In conclusion, our results indicate that patients even with one defined antineuronal antibody need to be regarded separately depending on the involved location of the nervous system. We recommend incorporation of anti-Hu analyses in the CSF and calculating the intrathecal synthesis in patients with anti-Hu syndrome.

Comparative evaluation of pain, tenderness and swelling followed by radiographic evaluation of periapical changes at various intervals of time following single and multiple visit endodontic therapy: an in vivo study.

AIM: This clinical study was undertaken to evaluate the postoperative sequelae following single-visit versus multiplevisit endodontic therapy at various interval of time in vital as well as nonvital teeth. MATERIALS AND METHODS: Thirty-two cases were randomly assigned to the following four groups, group I, group II, group III and group IV. After gaining the access to the pulp chamber, establishing the working length , thorough cleaning and shaping was done for all the cases. Obturation was done by protaper (variable taper) gutta-percha and AH-PLUS sealer using lateral and vertical condensation technique. All the cases were recalled after 48 hours, 1 week, 4 weeks and 6 weeks following obturation and were evaluated for postoperative pain, tenderness and swelling. RESULTS: There was no statistically significant difference amongst all the four groups in the incidence and severity of postoperative pain, tenderness and swelling at the end of one week. However, within 48 hours groups I, II and IV showed more pain when compared to group III. And groups I, II and III showed more tenderness compared with groups IV. Postoperative swelling was not reported. Radiographic investigation at the end of 6 weeks showed significant change in the appearance of the periapical region in group II and group IV cases. CONCLUSION: On strict adherence to biological principles and proper case selection, no significant difference in the success, postoperative pain and tenderness exist when treated with either single-visit or multiple-visit therapy. CLINICAL SIGNIFICANCE: No significant difference in the success rate or postoperative pain, tenderness, and swelling exists when treated with either single-visit or multiple-visit endodontic therapy. Hence, one can readily integrate one-visit endodontic therapy into the routine clinical practice of dentistry.

Are Patients Frequently Readmitted to the Hospital Different from the Other Admitted Patients?

INTRODUCTION: Although the characteristics of readmitted patients associated with a family medicine inpatient service have been reported, differing characteristics between groups of patients based on readmission rates have not been studied. The aim of this project was to examine patients with differing rates of readmission. METHODS: Patients admitted to a family medicine inpatient service were classified into 1 of 3 groups based on the number of admission and readmissions in a given year. Demographic data and other characteristics of these patients were collected and used in analysis. Descriptive statistics were used to characterize the 3 groups of admissions. Differences in characteristics of groups were compared using Wilcoxon rank sum test for continuous variables and χ2 test or Fisher exact test for categoric variables. Multivariate logistic regressions were used for predicting high-frequency readmission. RESULTS: Patients in the high-frequency readmission group more commonly had a psychiatric, substance abuse, and chronic pain diagnosis. The primary discharge diagnoses among the 3 groups were similar. Age-group, Charlson severity index, Morse Fall Scale medication list, and problem list were significant for predicting high frequency of readmission. Annually, patients in the high-frequency readmission group had about an 80% turnover rate. CONCLUSIONS: Although this study examined patient care data from only one large academic health center hospital, the results found that patients who experience 3 or more readmissions in a calendar are associated with specific characteristics. In addition, the list of specific individual patients considered to be high utilizers for hospital readmissions was dynamic and significantly changed during 3 consecutive years.

'Split posterior tooth': conservative clinical re-attachment.

Trauma is the prime causative factor for fracture of teeth/dentition. Many procedural management options are followed successfully in relation to the anterior teeth. However, most posterior cases where the tooth is fractured have only limited options to pursue to save the tooth. Fractured teeth, whether they are vital/non-vital, are predominantly managed with surgical options. This paper discusses a conservative approach to reattaching a split posterior tooth. A split tooth situation is mostly an absolute indication for extraction, but the clinician may go in for extensive surgical procedures if he/she wishes to save it. The reattachment of the tooth can be successfully done and it can be put to function. This paper discusses how a split posterior tooth can be treated successfully, although depending on multiple factors. A full crown cemented after successful reattachment and root canal therapy would provide sufficient support in order for the tooth to heal.
