Clonal diseases of large granular lymphocytes [see comments]

Three distinct clinical syndromes occur in patients with increased numbers of circulating LGL. Patients with T-LGL leukemia have clonal proliferations of CD3+ LGL typically associated with chronic neutropenia and autoimmune features. NK-LGL leukemia is characterized by clonal CD3- LGL proliferation with an acute clinical presentation marked by massive hepatosplenomegaly and systemic illness. However, most patients with increased numbers of CD3- LGL do not have clinical features of NK-LGL leukemia and have a chronic clinical course. X- linked gene analyses have supported a polyclonal LGL lymphocytosis in this syndrome. Further studies are needed to determine whether clonal progression can occur in these patients.     

Is rural radiation oncology practice quality as good as the big smoke? Results of the Australian radiotherapy single machine unit trial

Radiotherapy utilization rates in rural Australia are suboptimal, with one solution being the building of single machine units (SMUs). One concern raised with such an approach is the quality of care delivered in SMUs. The Australian and Victorian governments have established two SMUs in the state of Victoria, with each SMU operated as a satellite service of a major ‘hub’ site. We report on the planned evaluation of practice quality. Radiation oncologist (RO) clinical practice was externally audited using the Royal Australian and New Zealand College of Radiologists Peer Review Audit instrument. This tool splits RO clinical practice into documentation/quality assurance (QA) criteria and decision‐making criteria. Over the four sites, 130 patients were randomly selected for audit. At hub sites, 79.6% of all criteria audited were adequate, compared with 84.4% of criteria audited at SMUs (P = 0.0002). This difference was largely because of better adherence to documentation/QA criteria at the SMU sites. RO decision‐making and protocol adherence were routinely very high and consistent with other clinical practice audits. There were no significant differences between hubs and SMUs for adherence to decision‐making criteria; however, the few potential deficiencies in patient care identified occurred only at the hub sites. In at least one of these cases, potential suboptimal management was as a direct result of inadequate documentation. This audit found that SMUs provide as high a standard of radiotherapeutic care as larger hub departments. The findings also emphasize the need for all departments to target clinical documentation.     

Healing experiences after cervical cryosurgery

BACKGROUND: Treatment for cervical intraepithelial neoplasia with cryosurgery is uncomfortable for many women. The subsequent healing process is also thought to bring discomfort. The purpose of our study was to describe women's experiences after cryosurgery, and how obesity, age, and gravidity affected, the healing process. METHODS: We developed a survey from focus group results to measure the unpleasantness of hydrorrhea (watery discharge) from cryosurgery, the pad protection required, and the odor associated with the hydrorrhea. The cryosurgical experiences were compared with normal menses for the use and frequency of pad protection, medications used, and any activity restrictions. RESULTS: Cryosurgical experiences were unpleasant for 78.3% of the women because of the pain and cramping of the procedure and the resulting hydrorrhea, odor, and necessity of wearing pads for protection. These experiences after cryosurgery caused 38.6% to restrict their activities and 67.1% to take medications, a significantly greater proportion than the 16.9% whose activities were restricted normal menses and the 26.8% who took medications for normal menses (P=-.004, P <.001, respectively). In addition to these experiences, obese, multigravid, and older women were more bothered by the duration of wearing pads than their counterparts (P=.0246, =.0061, and P=.0159, respectively). CONCLUSIONS: Our study showed that the cryosurgical healing process was not pleasant, and was least tolerable for obese, multigravid, and older women. As many as 50% of women undergoing cryosurgery will perceive the hydrorrhea, its odor, and the wearing of pads to be worse than normal menses, especially if their menses are usually light.     

The natural history of cervical cryosurgical healing. The minimal effect of debridement of the cervical eschar [see comment

BACKGROUND: Cryosurgery is a favored treatment method for cervical intraepithelial neoplasia (CIN) among family physicians, in part because it is inexpensive and requires the least technical training and skill. Although cervical cryosurgery has been used for more than 30 years, the natural history of the postprocedure process has never been described. The primary purpose of our study was to describe the natural history of the healing process after cervical cryosurgery. A secondary purpose was to determine the effect of mechanical debridement of the cervical eschar on the symptoms of healing. METHODS: We conducted a prospective multicentered trial in which women who had a histologic ally documented CIN lesion underwent cervical cryosurgery. Forty-six women were randomized to undergo eschar debridement at 48 hours after cryosurgey, and 38 women received standard care. All women were followed up and given preweighed sanitary pads for hydrorrhea (watery discharge) collection and a diary to record the severity and number of days of odor, pain, cramping, and hydrorrhea that were experienced. RESULTS:The average total amount of hydrorrhea or discharge was 288 g, which required using an average of 41 sanitary pads during a period of 12.4 days. The duration of odor was 8.9 days, and the pain and cramping experienced after cryosurgery lasted 4.7 days. Women who were obese had greater hydrorrhea and pad usage than nonobese women. Debridement of the cervical eschar did not significantly change the signs and symptoms of healing after cryosurgery. CONCLUSIONS: There are significant symptoms patients experience after cryosurgery that are not ameliorated by debridement. The expectations of the cryosurgical healing process should be disclosed to women before the procedure.     

Local Anaesthesia for Fiberoptic Intubation : A Comparison of Three Techniques

Background

The successful conduct of fiberoptic aided intubation is dependent upon effective local anaesthesia. The aim of the study was to compare three different methods of anaesthetizing the airway.

Methods

60 adult patients (American Society of Anaesthesiologists status I-III and Mallampati class III & IV), scheduled for elective surgery, received sedation followed by spraying of the nares and posterior pharyngeal wall with 4% lignocaine. Thereafter the patients received 4 ml of 4% lignocaine either by transtracheal injection (n=20, group A), via intubating fiberscope (Pentax F1-10P2) using ‘spray as you go’ technique (n=20, group B) or by nebulizer (Devilbiss 5610W) 20 min before intubation, (n=20, group C). Patients were asked to score the procedure using visual analog scale (VAS) and severity scores. Episodes of coughing, choking, stridor, extra / total local anaesthetic used and intubation times were recorded. Patients were monitored continuously for vital parameters.

Results

Group B patients showed better VAS scores with shorter intubation times and had a lower incidence of coughing and choking. The endoscopists’ VAS scores also showed a preference for group B.

Conclusion

In conclusion the ‘spray as you go’ technique was safe, provided effective local anaesthesia and was preferred by both patients and endoscopists.Key Words: Awake intubation, Difficult airway, Fiberoptic intubation     

Chatting behavior and patient satisfaction in the outpatient encounter

Communication studies suggest that patient sociodemographic factors are embedded within medical encounters and impact patient expectations, judgments, and outcomes, such as satisfaction. Physician chatting has been suggested as one way to enhance patient satisfaction; however, little is known about chatting within the context of the clinical encounter or of the interaction of chatting with patient sociodemographic factors and patient satisfaction. The study's purpose was to determine the prevalence and patterns of chatting, and to examine the association of chatting with patient sociodemographic factors and patient satisfaction with their physician. A convenience sample of adult outpatients from an urban family practice underwent an exit interview. A total of 105 patients participated; 63 (61%) reported chatting from their recent encounter. No sociodemographic differences were observed between patients reporting chatting and those reporting no chatting. Chatting behavior pertaining to the patient's family or friends was the predominant topic, and more nonwhite (30%) than white (13%) patients reported this activity (p<0.001). There was no significant difference in satisfaction scores between patients that reported chatting behavior and those that did not (23.73 vs. 22.79, p=0.076). In addition, there was no difference in patient satisfaction scores for physician personal manner, technical skill, visit explanation, time spent with the physician, and overall visit between the chatting and nonchatting groups.     

Pain relief following Arthroscopy - a comparative study of Intra-articular Bupivacaine,Morphine and Neostigmine

Pain after arthroscopy is quite distressing. Intra-articular bupivacaine produces transient analgesia and reports of analgesia using intra-articular opioids have produced conflicting results. Recently, spinal administration of neostigmine was shown to produce dose-dependant analgesia. However, this was limited by adverse effects. The purpose of this study was to compare the effects on intra-articular neostigmine, bupivacaine and morphine. 75 patients were randomized to receive intra-articular saline, bupivacaine, morphine, neostigmine and bupivacaine-neostigmine after arthroscopic surgery under spinal anaesthesia. Visual analog pain scores (VAS), duration of analgesia as defined as time for first demand for parenteral opioids and the total subsequent consumption of morphine was evaluated. Intra-articular bupivacaine resulted in significant VAS reduction at one and four hours as compared to those receiving intra-articular saline and morphine. Analgesia lasted longer after 500ugm intra-articular neostigmine as compared with bupivacaine, morphine or saline. The need for supplementary analgesia was lowest in the neostigmine group as compared to the other groups. No significant difference was found if bupivacaine was added to neostigmine. Among all the groups, no significant side-effects were observed.Key Words: Arthroscopy, Bupivacaine, Morphine, Neostigmine     

The Spirituality Index of Well-Being: a new instrument for health-related quality-of-life research

PURPOSE: Despite considerable interest in examining spirituality in health-related quality-of-life studies, there is a paucity of instruments that measure this construct. The objective of this study was to test a valid and reliable measure of spirituality that would be useful in patient populations. METHODS: We conducted a multisite, cross-sectional survey using systematic sampling of adult outpatients at primary care clinic sites in the Kansas City metropolitan area (N = 523). We determined the instrument reliability (Cronbach's alpha, test-retest) and validity (confirmatory factor analysis, convergent and discriminant validation) of the Spirituality Index of Well-Being (SIWB). RESULTS: The SIWB contains 12 items: 6 from a self-efficacy domain and 6 from a life scheme domain. Confirmatory factor analysis found the following fit indices: chi2 (54, n = 508) = 508.35, P < .001; Comparative Fit Index = .98; Tucker-Lewis Index = .97; root mean square error of approximation = .13. The index had the following reliability results: for the self-efficacy subscale, alpha = .86 and test-retest r = 0.77; for the life scheme subscale, alpha = .89 and test-retest r = 0.86; and for the total scale alpha = .91 and test-retest r = 0.79, showing very good reliability. The SIWB had significant and expected correlations with other quality-of-life instruments that measure well-being or spirituality: Zung Depression Scale (r = 0-.42, P < .001), General Well-Being Scale (r = 0.64, P < .001), and Spiritual Well-Being Scale (SWB) (r = 0.62, P < .001). There was a modest correlation between the religious well-being subscale of the SWB and the SIWB (r = 0.35, P < .001). CONCLUSIONS: The Spirituality Index of Well-Being is a valid and reliable instrument that can be used in health-related quality-of-life studies.
