Envelope mastectomy with immediate reconstruction (EMIR).

AIMS: To develop an oncologically safe and aesthetically acceptable technique for mastectomy, using a muscle flap and tissue expander through one incision. METHODS: Twelve consecutive patients (mean age 40) underwent an envelope mastectomy (skin and nipple sparing), with immediate reconstruction with a latissimus dorsi muscle flap and tissue expander. Assessment of cosmesis was by review of pre- and post-operative photographs by an independent observer. RESULTS: During follow-up there have been no recurrences. Assessment of cosmesis gave a score of 44 out of 48 (92%). One prosthesis was removed due to erosion of the prosthesis through the skin. CONCLUSIONS: In patients with large lesions, multi-focal lesions (both invasive and in situ) and recurrent phyllodes tumours may undergo an oncologically safe mastectomy with immediate reconstruction through a single incision that is inconspicuous being in the mid-axillary line. Although follow up is only 8.5 months, long-term studies are being undertaken.

Defining the priority of using 18F-FDG PET for recurrent cervical cancer.

UNLABELLED: PET with 18F-FDG has shown its potential in cervical cancer. For maximizing the benefits of this new imaging technology, we aimed to define the prognostic features of recurrent cervical cancer patients for selecting appropriate candidates using 18F-FDG PET. METHODS: Patients enrolled were from 2 independent prospective studies investigating the role of 18F-FDG PET in cervical cancer patients after definitive treatment with documented failure (CTRP-018) or unexplained elevated tumor marker serum levels (CTRP-016) and proven relapse after PET. A total of 55 eligible patients received PET and CT or MRI. Lesion status was determined from pathologic results or clinical follow-up. The benefits calculated were based on treatment that was modified because of the PET findings. The Cox proportional hazards ratio (HR) was used to select independent prognostic covariates. RESULTS: Thirty-six (65.5%) patients had treatment that was modified due to PET. Primary radiation (HR = 14.62; 95% confidence interval [CI] = 2.74-77.92), squamous cell carcinoma antigen (SCC-Ag) > or = 4 ng/mL (HR = 5.82; 95% CI = 1.53-22.04), and presence of symptoms (HR = 6.24; 95% CI = 1.99-19.61) at recurrence were significant factors associated with poor survival. A scoring system using these covariates defined 3 distinct prognostic groups: score < or = 1 (HR = 1.00); score = 2 (HR = 6.91; 95% CI = 1.49-32.14); and score = 3 (HR = 60.46; 95% CI = 9.68-378.09) (P < 0.0001). CONCLUSION: Using this risk score, 18F-FDG PET may offer maximal benefits by selecting appropriate recurrent cervical cancer patients for salvage therapy with precise restaging information.

Relation between measurements of cough severity.

BACKGROUND: In asthma, measurements of airway inflammation correlate poorly with clinical markers and airway hyperresponsiveness. While the relation between determinants of asthma severity is known, that for cough is unknown. We hypothesised that cough sensitivity changes relate to changes in cough scores and objectively measured cough frequency. AIMS: To examine the relation between commonly used outcome measurements of cough severity in children. METHODS: The concentration of capsaicin causing two and five or more coughs (C2 and C5 respectively), cough frequency objectively measured using an ambulatory cough meter, and parent and child recorded subjective cough scores were determined in 40 children with recurrent cough on two occasions. RESULTS: On occasion one, log cough frequency significantly correlated with parent and child recorded log cough score (r(s) = 0.32, p = 0.05; and r(s) = 0.32, p = 0.046 respectively) and significantly negatively correlated with log C2 (r(s)= -0.5, p = 0.005). Subjective cough scores did not relate to either C2 or C5. On occasion two, the relation between cough frequency and C2 and C5 measures was lost, but C2 had a weak but significant relation to parent recorded cough score (r(s) = -0.38, p = 0.047). When the changes in the log values were determined, C5 but not C2 significantly related to cough frequency. CONCLUSION: In children, measures of cough sensitivity have a weak relation with cough frequency. Subjective cough scores have a stronger and consistent relation with cough frequency. These cough severity indices measure different aspects of cough. The choice of indices depends on the reason for performing the measurement.

[Etiology of the recurrence of lumbar intervertebral disk displacement].

In a review for reasons of 100 disc prolapses reoperations we found in 62% a recurrence of disc prolapse at the same level, in 24% a recurrence at a different level, whereas in 14% we found that the nerve route was closely connected. We reoperated 44% in the first two years and 69% in the first five years. The time between the operations was prolonged if there was a short period of time for relief of pain after operation and a long period of preoperative symptoms. The variables of risk of a disk prolapse recurrence are recorded in a risk score, in which 64% of the patients belonged retrospectively to a risk group. The correlation between operation interval and score points showed that patients with short interval had high score ratings.

Long-term outcome following radical prostatectomy in men with clinical stage T3 prostate cancer.

PURPOSE: We evaluated patients at our institution who underwent radical prostatectomy for clinical stage T3 prostate cancer to determine their long-term clinical outcomes. MATERIALS AND METHODS: We reviewed our prospective surgical database and identified 176 men who underwent radical retropubic prostatectomy for clinical stage T3 prostate cancer from 1983 to 2003. Clinical and pathological data were reviewed and evaluated in a Cox proportional hazards model to determine preoperative predictors of biochemical recurrence. Clinical progression following biochemical recurrence was evaluated and clinical failure was defined as the development of clinical metastases or progression to hormone refractory prostate cancer. RESULTS: Of the 176 patients with cT3 prostate cancer 64 (36%) received neoadjuvant hormonal therapy. At a mean followup of 6.4 years 84 (48%) patients had disease recurrence with a median time to biochemical recurrence of 4.6 years. The actuarial 10-year probability of freedom from recurrence was 44%. On multivariate analysis biopsy Gleason score, pretreatment serum prostate specific antigen and year of surgery were independent predictors of biochemical recurrence. Neoadjuvant hormonal therapy was not a significant predictor of biochemical recurrence. Following biochemical recurrence clinical failure developed in 30 of 84 (36%) men with a median time of 11 years. Overall the 5, 10 and 15-year probabilities of death from prostate cancer were 6%, 15% and 24%, respectively. CONCLUSIONS: More than half (52%) of our patients remained free of disease recurrence following radical prostatectomy. In our series neoadjuvant hormonal therapy offered no advantage with respect to disease recurrence. Radical prostatectomy remains an integral component in the treatment of select patients with clinical stage T3 prostate cancer.

Modified laparoscopic nephroureterectomy for treatment of upper urinary tract transitional cell cancer is not associated with an increased risk of tumour recurrence.

INTRODUCTION: Laparoscopic nephroureterectomy reduces the morbidity of surgical management of urinary tract transitional cell carcinoma (TCC), but a potentially increased risk for local tumour spreading was reported. We evaluated results obtained from patients undergoing a modified laparoscopic approach and open procedures in this respect. PATIENTS AND METHODS: Between January 2000 and March 2002 we performed 19 modified laparoscopic nephroureterectomies (LNU) with open intact specimen retrieval in conjunction with open distal ureter and bladder cuff removal and 15 open standard nephroureterectomies (ONU). Staging lymphadenectomy was performed in 14/19 (73.7%) patients with LNU and in 6/15 (40.0%) with ONU. In all patients operating time, blood loss, complications, pain score (VAS) and data in respect to tumour recurrence were analysed. Mean follow-up was 22.1+/-9.2 (range 14-34) months for LNU and 23.1+/-8.8 (14-36) for ONU respectively. RESULTS: In LNU and ONU pathological features were 12 pT1 vs. 10 pT1, 2 pT2 vs. 2 pT2 and 5 pT3 vs. 3 pT3, respectively. All patients had TCC and were R0 at final histology. Four patients with LNU had lymph node involvement, one in ONU. LNU had decreased operating times (p=0.057), blood loss (p=0.018), complications (p=0.001) and VAS scores (p=0.001). One tumour recurrence occurred in LNU, associated with a pT3b pN2 G3 TCC at final histology. One patient with ONU had local tumour recurrence at the site of the bladder cuff. No port-site metastasis occurred during follow-up with LNU. CONCLUSION: Improved peri-operative results and same cancer control as compared to open surgery by this modified LNU was not associated with an increased risk for tumour recurrence, since strict "non-touch" preparation, avoiding of urine spillage and intact specimen retrieval prevents tumour seeding. However, results from long term studies are still warranted to clarify this issue.

Predictors of postoperative distant recurrences in esophageal carcinoma.

Pathologic factors and the number of nucleolar organizer region proteins (AgNORs) were evaluated as predictors of postoperative recurrence in distant organs in 92 patients with curatively resected esophageal carcinoma. The rate of distant recurrence was significantly higher in patients with venous invasion (53%; 19 of 36) than in those without invasion (21%; 12 of 56) (p < 0.01) and was also higher in patients with an AgNOR score greater than or equal to 4 (49%; 19 of 39) than in those with an AgNOR score less than 4 (23%; 12 of 53) (p < 0.02). The rate of recurrence was significantly higher in patients with both venous invasion and AgNOR score greater than or equal to 4 (67%; 16 of 24) than in the other patients. These findings indicate that the combination of venous invasion and a high AgNOR score predicts distant postoperative recurrences in patients with curatively resected esophageal carcinoma.

Markers and meaning of primary treatment failure.

BCR is the most clinically used endpoint for identification of treatment failure. Approximately 15% to 53% of patients undergoing primary curative therapy will develop BCR. BCR often precedes clinically detectable recurrence by years. It does not necessarily translate directly into PCa morbidity and mortality, nor does it always reflect the desired endpoint. Furthermore, it has not been validated as a surrogate endpoint, in that interventions that have been shown to alter the PSA level have not been shown to also alter survival. The utility of PSA level as a surrogate endpoint is brought into question by the knowledge that the overall survival rate of patients at 10 years is similar in patients with and without BCR, and that in a significant proportion of men, the only evidence of disease during their lifetime will be a detectable PSA level. The likelihood of developing BCR post-therapy can be predicted by using multiple clinical and pathologic variables. With the development of nomograms that incorporate several markers, the accuracy of prediction has improved. Until recently, the natural history of BCR post-RRP has not been well understood. Pound et al showed the heterogenous and prolonged natural history of BCR. In this large series of men with BCR following RRP, only 34% of men developed metastatic disease. The median time from development of BCR to identification of metastases was 8 years, and the median time from the development of metastatic disease to death was just under 5 years. These data highlight the extremely variable and potentially indolent nature of BCR. The risk of metastatic disease following BCR has been relatively well defined and relates to PSADT and time to PSA recurrence. It generally is accepted that a PSADT of less than 6 to 10 months and a time to PSA recurrence of less than 1 to 2 years relates to a higher risk of developing metastatic disease. Local recurrence, however, remains poorly understood with respect to its true incidence, clinical significance, and natural history. The significance of BCR post-RT remains unclear due to the lack of data on its natural history. Attempts have been made to identify patients at high risk for metastatic progression by looking at time to PSA recurrence and PSADT. A PSADT of less than 6 to 12 months and a time to PSA recurrence of less than 12 months reflects a higher risk of developing metastatic disease. Accurate risk stratification by means of an algorithm similar to that produced by Pound et al has not been performed on a large cohort, thus making risk assessment for an individual patient difficult. The major dilemma for clinicians in the management of BCR is the identification of the site of disease recurrence, which ultimately guides therapy decisions. Clinicopathologic features allow for risk stratification for recurrence, and multiple investigations have attempted to localize the site of recurrence. Time to biochemical progression, Gleason score, and PSADT are predictive of the probability and time to development of metastatic disease, and allow for stratification of patients into different risk groups (see Table 2). TRUS, CT, PET, and DRE all have limited utility in the identification of local recurrence. ProstaScint and MRI have demonstrated encouraging initial results: however, they require further investigation. Bone scintigraphy is of little value for the initial investigation of BCR. In patients with a PSA level of less than 10 ng/mL, the risk of having a positive bone scan is less than 1% and, until the PSA level rises above 40 ng/mL, the risk of having a positive bone scan is less than 5%. Therefore, bone scintigraphy should be reserved for patients with a PSA level greater than 10 to 20 ng/mL or patients with a rapidly rising PSA level. Using new MRI sequences, there is some evidence that MRI is better for the detection of bony metastatic disease; however, this technique requires further investigation. BCR causes anxiety for the patient and the treating doctor, because the best way to manage patients with PSA-only progression is unknown. Currently, there are no validated treatment recommendations for the management of BCR. The information in this review provides the framework for assignment of patients into clinical trials based on different risk categories. Patients at high risk for metastatic progression could be identified early and thus entered into appropriate clinical trials for systemic therapies. Similarly, patients with a low risk of progression could be placed into observation protocols, potentially sparing them from exhaustive and inappropriate investigations.

Surgical treatment of venous malformations in Klippel-Trénaunay syndrome.

PURPOSE: Klippel-Trénaunay syndrome (KTS) is a complex congenital anomaly, characterized by varicosities and venous malformations (VMs) of one or more limbs, port-wine stains, and soft tissue and bone hypertrophy. Venous drainage is frequently abnormal because of embryonic veins, agenesis, hypoplasia, valvular incompetence, or aneurysms of deep veins. We previously reported on the surgical management of KTS. In this article, we update our experience. METHODS: Twenty patients with KTS underwent surgical treatment for VMs between July 1, 1987, and January 1, 2000. This group represented 6.9% of 290 patients with KTS who were seen at our institution during this 12.5-year study period. Surgical indications, venous anatomy (determined with duplex scan, contrast phlebography, magnetic resonance imaging or magnetic resonance phlebography), operative procedures, and complications were reviewed, and outcomes were recorded. RESULTS: Twelve male and eight female patients (mean age, 23.4 years; range, 7.7-40.6 years) underwent 30 vascular surgical procedures in 21 lower limbs. All 20 patients (100%) had varicose veins or VMs, 13 (65%) had port-wine stains, and 18 (90%) had limb hypertrophy. Pain was the most common complaint, which was present in 16 patients (80%), followed by swelling in 15 (75%), bleeding in 8 (40%), and superficial thrombophlebitis and cellulitis in 3 (15%). Imaging confirmed patent deep veins in 18 patients, hypoplastic femoral vein in 1, and entrapped popliteal veins bilaterally in 1. Four patients (20%) had large persistent sciatic veins (PSVs). The CEAP clinical classification was C-3 for 17 patients (85%), C-4 for 1 patient (5%), and C-6 for 2 patients (10%). Stripping of large lateral veins, avulsion, and excision of varicosities or VMs were performed on all limbs. Three patients required staged resections. The release of entrapped popliteal veins was performed in both limbs of one patient; another underwent a popliteal-saphenous bypass graft. One patient underwent excision of a PSV. Open and endoscopic perforator vein ligation was performed in one patient each. Two patients (12%) had hematomas that required evacuation. No patients had caval filter placement; none had postoperative deep venous thrombosis or pulmonary embolus. The mean follow-up was 63.6 months (range, 0-138 months). All patients reported initial improvement, but some varicosities recurred in 10 patients (50%), an ulcer did not heal in one, and a new ulcer developed in one, 8 years after surgery. Three patients underwent reoperation for recurrent varicosities. Follow-up CEAP scores were C-2 in 10 patients (50%), C-3 in 6 patients (30%), C-4 and C-5 in 1 patient each (5%), and C-6 in 2 patients (10%). Clinical scores improved from 4.3 +/- 2.2 to 3.1 +/- 2.3. (P =.03). CONCLUSIONS: The management of patients with KTS continues to be primarily nonoperative, but those patients with patent deep veins can be considered for excision of symptomatic varicose veins and VMs. Although the recurrence rate is high, clinical improvement is significant, and reoperations can be performed if needed. Occasionally, deep vein reconstruction, excision of PSVs, or subfascial endoscopic perforator surgery is indicated. Because KTS is rare, patients should receive multidisciplinary care in qualified vascular centers.

Evaluation of argyrophilic nucleolar organizer regions (AgNORs) in differentiated thyroid carcinoma as an indicator for disease recurrence.

Differentiated thyroid carcinoma (DTC) is one of the least aggressive cancers of the human malignancies, however, recurrent disease is occasionally found and is difficult to determine the risk for recurrence only by clinicopathological features. In the present study, we investigated argyrophilic nucleolar organizer regions (AgNORs) score, a well-known indicator for proliferative potential of the cancer cells, in 89 cases of DTC. In tumors with capsular invasion, or with extended contra-lateral lymph node metastasis, AgNORs score was significantly higher than in tumors without them, while was not correlated with age or gender of the patients, nor the histological type of the tumor (papillary or follicular). Disease recurrence was observed in one-third of the patients in high AgNOR score group (scored more than mean value +/- standard deviation) when the patients were divided into four groups according to the AgNOR score, and a significantly higher risk for disease recurrence was demonstrated in those cases with high AgNOR score than cases with lower score. These results clearly indicated the usefulness of AgNOR score in selecting the patients at high risk for disease recurrence. All 5 recurrent cases displayed local recurrence in high AgNOR score group, while 5 of 7 cases with low AgNOR score did in the manner of hematological metastasis. In conclusion, this method was technically simple and accurate giving an exact value in individual cases. Thus, we believe AgNOR score might be clinically applicable as a useful indicator for disease recurrence in DTC.

Long-term benefits of elective radiotherapy after prostatectomy for patients with positive surgical margins.

PURPOSE: The benefit of adjuvant radiotherapy after prostatectomy for patients with pathological risk factors but with an undetectable postoperative PSA remains controversial. In this retrospective study we define the benefits of elective postoperative radiotherapy in this setting. MATERIALS AND METHODS: A total of 44 patients received elective postoperative radiotherapy at a single institution in the PSA era (1989 to 1995) for positive surgical margins and undetectable postoperative PSA. Radiotherapy was delivered to a median dose of 60 Gy. Clinical target volume included the prostate bed. Pelvic nodes were not treated. The four-field box technique with customized blocking of bladder, rectum and small bowels was used and defined the planning target volume. The patients were then compared to a contemporaneous group of 189 patients with positive surgical margins who underwent radical prostatectomy without any adjuvant therapy. Failure was defined as biochemical (PSA) recurrence and was timed from first detectable PSA. RESULTS: The 5 and 10-year biochemical no evidence of disease was 90.9% and 90.9% for the elective postoperative radiotherapy group, and 66.4% and 54.5% for the observation group, respectively (p = 0.0012). Median time to biochemical failure was also longer in the elective postoperative radiotherapy group (88.6 months) compared to the observation group (43.5 months) (p <0.001). Risk factors for biochemical recurrence on multivariate analysis were Gleason score greater than 7 (p = 0.017), established extracapsular extension (p = 0.002) and lack of elective postoperative radiation (p = 0.001). CONCLUSIONS: This is one of the longest followup studies showing that elective postoperative radiation therapy is associated with improved bNED and prolonged time to recurrence. Combined radical prostatectomy and elective postoperative radiotherapy should be considered in the management of high risk prostate cancer, especially in the presence of positive surgical margins despite undetectable PSA.

Arthroscopic transglenoid multiple suture repair: 2 to 8 year results in 150 shoulders.

One hundred fifty-six arthroscopic transglenoid multiple suture repairs were performed for chronic anterior shoulder instability. In 150 shoulders (96% follow-up), the outcome with respect to recurrence of instability and the Bankart Score was determined a minimum of 2 years and a mean of 4.1 years after surgery (range, 2 to 8.2 years). During the follow-up interval, 11 shoulders (7.3%) redislocated. Fourteen other shoulders (9.3%) had at least one episode that we interpreted as recurrent subluxation. Shoulders with a Bankart lesion and younger patients had a higher probability of recurrent instability (P < .05). We concluded that this method is most effective in shoulders without a Bankart lesion and in patients older than 25 years of age (regardless of pathology).

Life satisfaction and associated factors in older Hong Kong Chinese.

OBJECTIVE: To determine life satisfaction and its association with physical, functional, socioeconomic, psychological, and social support characteristics in Hong Kong Chinese aged 70 years and older. DESIGN: Cross-sectional study. SETTING: Territory-wide random sample of persons aged 70 years and older. SUBJECTS: A total of 843 men and 714 women were selected by random sampling, stratified by age and sex, from the Old age and Disability Allowance Register, after exclusion of subjects with cognitive impairment. MEASUREMENTS: Life satisfaction was assessed by the subjects' response to the question "Are you satisfied with life", using a 0 to 10-point linear scale. They were also asked to name the most important factor contributing to life satisfaction. Information was also obtained regarding physical health, functional ability, depressive symptoms, and socioeconomic factors. RESULTS: There was a weak association between score and age. Health, adequate income to meet living expenses, and caring relatives were rated the most important factors (> 65%). Some of these factors were also those associated with a high life satisfaction score. Factors associated with a life satisfaction score greater than 6 points were higher social class and educational attainment, adequate income to meet living expenses, satisfactory living arrangement, Christianity, good social support, participation in social activities, functional independence, good self-perceived health, good hearing and vision, daily exercise, absence of recurrent falls, and low depressive symptom score. Multiple logistic regression identified having two or more relatives and tertiary education as positive associated factors, whereas inadequate income to meet expenses, dissatisfaction with living arrangement, nonparticipation in religious group activities, and a high depressive symptom score were negative associated factors. CONCLUSION: In older Chinese, social factors such as the support provided by family members, as well as adequate income to meet living expenses, play a role equal to that of physical factors in contributing to life satisfaction.

Reconstruction after intercalary resection of malignant bone tumours: comparison between segmental allograft and extracorporeally-irradiated autograft.

We reviewed 29 patients who had undergone intercalary resection for malignant tumours. Of these, 14 had received segmental allograft reconstruction and 15 extracorporeally-irradiated autograft. At a mean follow-up of 71 months (24 to 132), 20 were free from disease, five had died and four were alive with pulmonary metastases. Two patients, one with an allograft and one with an irradiated autograft, had a local recurrence. Reconstruction with extracorporeally-irradiated autograft has a significantly lower rate of nonunion (7% vs 43%, p = 0.031) but an insignificantly higher rate of fracture (20% vs 14%, p = 0.535) than that with segmental allograft. Using the Enneking functional evaluation system, the mean postoperative score for the patients without local recurrence was 87% (80% to 96%) and was similar in both groups. Extracorporeally-irradiated autograft could be an acceptable alternative for reconstruction after intercalary resection, especially in countries where it is difficult to obtain allografts.

Perianal Crohn disease: a new scoring system to evaluate and predict outcome of surgical intervention.

BACKGROUND: Conventional Crohn disease activity indices do not reflect perianal disease activity or allow prognostic implications from surgery. HYPOTHESIS: A new scoring system, based on the patient's disease history and physical examination findings, will allow more accurate use of surgical intervention for perianal Crohn disease. METHODS: A standardized scoring questionnaire was developed and applied to a consecutive group of patients before surgical treatment of perianal Crohn disease. The scoring system included abscess, fistula, ulcer and fissure, stenosis, incontinence, and concomitant disease. Weighted factors included acuity vs chronicity, de novo vs recurrent disease, and concomitant intestinal disease. The scoring system was validated against the surgical outcome, which was classified as poor, satisfactory, or good. RESULTS: Twenty-eight patients with Crohn disease who underwent 33 surgical procedures had a mean score of 16.5 (range, 3-37; possible range, 0-55). Using the Spearman nonparametric correlation test, the scoring system was accurate in predicting the outcome of surgical intervention (correlation coefficient, 0.78, 95% confidence interval, 0.57-0.89; P<.001) at mean follow-up of 20.8 months (range, 6-40 months). Correlation was further validated using a linear regression model (r = 0.75, slope best-fit value, 3.8; 95% confidence interval, 2.46-5.14; P<.001). All patients with a score of 10 or less had a good outcome, whereas all those with a score of 20 or greater had a poor outcome. CONCLUSIONS: The proposed scoring system correlated well with the short-term outcome of surgical intervention in patients with perianal Crohn disease and allowed prediction of surgical success. Ultimately, it may be possible to alter therapy based on preoperative prediction of the expected postoperative outcome.

Monitoring for atrophic rhinitis: the problem of higher snout scores.

The Pig Health Control Association has run a monitoring scheme for atrophic rhinitis for 10 years. One criterion for qualification has been that the average six-monthly snout score should not exceed 0.5 (later 0.65). Eighteen qualifying herds have exceeded this limit on 56 occasions, with their average scores rising to 2.24; they were the subject of special investigations for relisting. No clinical, epidemiological or bacteriological evidence could be found to indicate that these herds were capable of developing severe atrophic rhinitis. The higher snout scores were associated with a group of recurrent husbandry factors, especially overstocking and unsatisfactory conditions in the weaner accommodation. It is possible that the upper limit for the snout score in qualifying herds could be raised considerably, thus confining bacteriological testing to more doubtful herds.

Interventions for treating depression after stroke.

BACKGROUND: Depressive and anxiety disorders following stroke are often undiagnosed or inadequately treated. This may reflect difficulties with the diagnosis of abnormal mood among older people with stroke-related disability, but may also reflect uncertainty about the effectiveness of such therapies in this setting. OBJECTIVES: To determine whether pharmacological, psychological, or electroconvulsive treatment (ECT) of depression in patients with stroke can improve outcome. SEARCH STRATEGY: The Cochrane Stroke Group Trials Register (last searched June 2003). The Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 3, 2002), MEDLINE (1966 to September 2002), EMBASE (1980 to September 2002), CINAHL (1982 to September 2002), PsychINFO (1967 to September 2002), Applied Science and Technology Plus (1986 to September 2002), Arts and Humanities Index (1991 to September 2002), Biological Abstracts (1969 to September 2002), General Science Plus (1994 to September 2002), Science Citation Index (1992 to September 2002), Social Sciences Citation Index (1991 to September 2002), and Sociofile (1974 to September 2002). Reference lists from relevant articles and textbooks were searched, and authors of known studies and pharmaceutical companies who manufacture psychotropic medications were contacted. SELECTION CRITERIA: Randomised and quasi-randomised controlled trials comparing different types of pharmaceutical agents with placebo, or various forms of psychotherapy with standard care (or attention control), in patients with recent, clinically diagnosed, acute stroke, where treatment was explicitly intended of treat depression. DATA COLLECTION AND ANALYSIS: Primary analyses focussed on the prevalence of diagnosable depressive disorder at the end of treatment. Secondary outcomes included depression or mood scores on standard scales, disability or physical function, death, recurrent stroke, and adverse effects. We did not pool the data for summary scores. We performed meta-analysis for only some binary endpoints and data on adverse events. MAIN RESULTS: Nine trials, with 780 participants, were included in the review. Data were available for seven trials of pharmaceutical agents, and two trials of psychotherapy. There were no trials of ECT. The analyses were complicated by the lack of standardised diagnostic and outcome criteria, and differing analytic methods. There was no strong evidence of benefit of either pharmacotherapy or psychotherapy in terms of a complete remission of depression following stroke. There was evidence of a reduction (improvement) in scores on depression rating scales, and an increase in the proportion of participants with anxiety at the end of follow up. REVIEWERS' CONCLUSIONS: This review found no evidence to support the routine use of pharmacotherapeutic or psychotherapeutic treatment for depression after stroke. More research is required before recommendations can be made about the most appropriate management of depression following stroke.

Smoking has a negative impact upon health related quality of life after treatment for head and neck cancer.

To examine the influence of smoking on observer based morbidity scores and patient assessed health related quality of life after treatment for head and neck cancer. The results of EORTC C30 and H&N35 questionnaires and DAHANCA morbidity scores were studied according to smoking status in 114 recurrence free head and neck cancer patients. In contrast to observer based toxicity scoring, smoking had a significantly negative influence on 20 of the 33 quality of life scales. Previous smokers had quality of life scores in between never smokers and continuous smokers. Smoking after treatment of head and neck cancer adversely influenced a wide range of quality of life endpoints. Quitters had better quality of life than patients who continued to smoke after treatment, suggesting that smoking cessation may improve quality of life in addition to reducing the risk of new cancer.
