Identification of Risk Factors for Postoperative Nausea and Vomiting in the Perianesthesia Adult Patient

Postoperative nausea and vomiting (PONV) is a common and potentially debilitating complication of surgery. The preoperative assessment of PONV using established risk assessment tools enables the identification of patients at risk and potentially decreases the incidence of PONV in adult surgical patients. The identification of risk factors associated with PONV and the factors that are independent predictors of PONV preoperatively can facilitate the effective prophylactic treatment and management of PONV in adult surgical patients.     

Command hallucinations among Asian patients with schizophrenia.

OBJECTIVES: The impact of command hallucinations on patients and the determinants of patients' compliance with them are still poorly understood. The extant literature is also divided on their association with violence. This study aimed to establish the prevalence of command hallucinations and to identify the factors that affect compliance with the commands, together with patients' coping methods. METHODS: We recruited 50 consecutive male and 50 consecutive female schizophrenia inpatients who reported hearing voices in the 6 months prior to admission. We interviewed these patients, using a semistructured questionnaire. We collected information on the contents of their auditory hallucinations and their coping methods. RESULTS: Of the patients, 53 (53%) reported command hallucinations. Of these 53 patients, 58% were women and 48% were men; 62% reported complying with the commands. They were also more likely to comply with nonviolent commands. A history of self-harm predicted compliance. Those patients who did not comply with the commands adopted various methods of coping, of which praying was the most common. CONCLUSION: Command hallucinations are common in patients with schizophrenia. Patients with a history of self-harm need closer monitoring because they may be more likely to comply with these hallucinations. Assessment should also include the patient's own coping strategies, which can be incorporated into the treatment.

Early experience with minimally invasive esophagectomy in head and neck surgical patients

BACKGROUND: Minimally invasive esophagectomy (MIE) via thoracoscopy and laparoscopy have reduced the morbidity and mortality of total esophagectomy at experienced centers. MIE has not been evaluated in combination with major head and neck surgery, or in the otolaryngology literature. METHODS: Case series of 11 consecutive patients undergoing either open or MIE with an ablative neck procedure. RESULTS: Comparing 4 MIEs and 7 open operations, similar operative time, blood loss, and ICU and hospital length of stay were observed. There was one mortality in the open group. A 100% rate of major complications was observed in the MIE group. CONCLUSION: Our multidisciplinary team was unable to achieve improved outcomes in a series of head and neck surgical patients undergoing MIE. This result may represent an early stage of the learning curve for MIE, but may also be attributed to the escalated surgical requirements of head and neck patients.     

Adenocarcinomain Situof the Uterine Cervix: Management and Outcome

Objective: To retrospectively review the management of adenocarcinomain situof the uterine cervix, to determine the outcome of conization versus hysterectomy, and to compare the results achieved by different methods of conization. Methods: We performed a retrospective pathology and chart review of 46 patients with cervical adenocarcinomain situfrom January 1980 to October 1994. Results: Nine patients were managed during the first half of the study period and 37 were managed in the second half. The mean age of patients was 38.4 years (range 25–72). Forty-five of 46 patients were diagnosed as a result of an abnormal Pap smear, although only 19 smears indicated adenocarcinomain situor other glandular abnormalities. Cold knife conization resulted in a 33% rate of positive margins for adenocarcinomain situcompared to 50% for large loop excision of the transformation zone (LLETZ). Among 24 conservatively managed patients with negative conization margins, there have been 2 (8.3%) recurrences of adenocarcinomain situ.Among patients not undergoing hysterectomy as definitive treatment, 1 of 18 (6%) patients undergoing cold knife conization recurred, compared to 4 of 14 (29%) managed with LLETZ, despite a 63.4-month shorter mean follow-up interval for the LLETZ patients. Conclusions: Cold knife conization is associated with a lower rate of recurrence of cervical adenocarcinomain situcompared to LLETZ. We recommend cold knife conization for patients who are not treated with hysterectomy.

Mononuclear-cell subsets in human idiopathic crescentic glomerulonephritis (ICGN): Analysis in tissue sections with monoclonal antibodies

Mononuclear inflammatory cells (MIC) were analyzed in renal biopsies from 16 patients with ICGN (7 with glomerular immune complex deposits, 3 with anti-GBM disease, and 6 without immune deposits) by the avidin-biotin-immunoperoxidase technique utilizing monoclonal antibodies to cell surface antigens: T11 (total T), T4 (inducer/helper T), T8 (suppressor/cytotoxic T), B1 (B cells), M1 (monocytes/granulocytes), and Leu 7 [natural killer (NK) cells]. Total MIC were significantly increased in both glomeruli and interstitial tissues of the patients. Interstitial MIC consisted mainly of lymphocytes (80%) and monocytes (19%), with small numbers of B and NK cells present. In contrast, MIC in renal glomeruli of patients with ICGN were composed of monocytes (65%) rather than T lymphocytes (34%). A majority of T lymphocytes found in renal tissues of patients and controls had the helper/inducer phenotype. Tissue T4/T8 ratios were not significantly different in the glomeruli and interstitium. Monocytes and T lymphocytes accumulating in renal tissues of patients with ICGN may mediate glomerular injury in all forms of human ICGN.Presented in part at the 15th Annual Meeting of the American Society of Nephrology, Chicago, Illinois, 1982.     

Identification of Potential Diagnostic and Vaccine Candidates of Helicobacter pylori by Two-Dimensional Gel Electrophoresis, Sequence Analysis, and Serum Profiling

There is great interest in characterizing the proteins of the gastric pathogen Helicobacter pylori, especially those to which humans respond immunologically, because of the potential importance of such proteins in diagnosis and vaccine development. Two-dimensional gel electrophoresis was used to separate and identify potential antigens of H. pylori ATCC 43504. Over 30 proteins were reactive in Western blots with pooled sera from 14 infected patients. These proteins were analyzed by N-terminal sequence analysis. Fourteen proteins were determined to be distinct from any proteins previously described from H. pylori; the others were previously isolated and characterized proteins. Analysis of eight distinct H. pylori strains showed that most of these antigens were produced by all of the strains. We propose that collection of new antigens such as those recognized here will be useful in serologic tests for detecting and monitoring H. pylori infection and may also serve as potential targets for antimicrobial agent or vaccine development.
