Reduction of nightmares and other PTSD symptoms in combat veterans by prazosin: a placebo-controlled study.

OBJECTIVE: Prazosin is a centrally active alpha(1) adrenergic antagonist. The authors' goal was to evaluate prazosin efficacy for nightmares, sleep disturbance, and overall posttraumatic stress disorder (PTSD) in combat veterans. METHOD: Ten Vietnam combat veterans with chronic PTSD and severe trauma-related nightmares each received prazosin and placebo in a 20-week double-blind crossover protocol. RESULTS: Prazosin (mean dose=9.5 mg/day at bedtime, SD=0.5) was superior to placebo for the three primary outcome measures: scores on the 1) recurrent distressing dreams item and the 2) difficulty falling/staying asleep item of the Clinician-Administered PTSD Scale and 3) change in overall PTSD severity and functional status according to the Clinical Global Impression of change. Total score and symptom cluster scores for reexperiencing, avoidance/numbing, and hyperarousal on the Clinician-Administered PTSD Scale also were significantly more improved in the prazosin condition, and prazosin was well tolerated. CONCLUSIONS: These data support the efficacy of prazosin for nightmares, sleep disturbance, and other PTSD symptoms.

Imaging changes of the pancreas and the occasion of refeeding in patients with acute pancreatitis.

OBJECTIVE: To explore the objective basis of the time and characteristics of refeeding of patients with acute pancreatitis (AP). METHODS: AP patients were randomly divided into routine group (n=105) and special group (n=99). The refeeding time and characteristics of the routine group were based on their levels of blood and urine amylase, function of the gastrointestinal tract, and symptoms and signs, and those of the special group on their imaging changes of ultrasonography and CT of the pancreas. Clinical data from the groups were analyzed prospectively and statistically. RESULTS: At the beginning of refeeding, patients of the two groups showed a high recurrence rate of abdominal pain (routine group, 9.1%; special group, 10.5%), but no AP relapse. Three days to 2 weeks after refeeding, the patients of the routine group had a higher recurrence rate of abdominal pain (11.1%) and a relapse rate of AP(14.1%) as compared with those of the special group (P<0.05). Two weeks later, both rates decreased apparently. However, 3 days to 4 weeks after refeeding, the patients of the special group had no recurrence of abdominal pain and relapse of AP. Imaging changes of the pancreas and peripancreatic tissue were not consistent with the symptoms and signs of AP patients. The higher the Balthazar CT grading and APACHE-II score, the higher the recurrence rate of abdominal pain and the relapse rate of AP after refeeding (P<0.05). CONCLUSIONS: Symptoms and signs were usually discordant to the imaging changes of the pancreas in AP patients. Imaging changes of the pancreas might serve as a basis for the best occasion of refeeding light semi-fluid or light food in AP patients.

Which elderly depressed patients remain well on maintenance interpersonal psychotherapy alone?: report from the Pittsburgh study of maintenance therapies in late-life depression.

The aim of this study was to identify elderly depressed patients who can remain well on maintenance Interpersonal Psychotherapy (IPT) alone, after discontinuation of antidepressant medication. Using Cox proportional hazards models, increased severity of depression at pretreatment was associated with increased recurrence rates, to an extent greater in patients maintained on monthly IPT than in those maintained on nortriptyline. The long-term response to maintenance IPT was correctly identified in 20/25 cases by a pretreatment Hamilton score of > or = 20. Fourteen of sixteen patients with pretreatment scores of > or = 20 experienced recurrence of major depression on maintenance IPT, while 6/9 patients with pretreatment scores of less than 20 did not. (Fisher exact P = .01). The same pattern of recurrence in relation to severity was not evident in maintenance placebo, nortriptyline, or combination treatment. In addition, Hamilton scores during continuation treatment were lower (< or = 7) among those who remained well on maintenance IPT than among those who had recurrences. Elderly patients whose depressions are milder at baseline and who show excellent symptomatic remission during acute and continuation therapy may be good candidates for monthly maintenance IPT after initial successful treatment with antidepressant medication and psychotherapy.

The functional assessment of cancer-vulvar: reliability and validity.

OBJECTIVES: To assess the reliability and validity of the Functional Assessment of Cancer Therapy-Vulvar (FACT-V). METHODS: Seventy-seven patients treated between January 1996 and January 2001 for cancer of the vulva completed the FACT-V, the Eastern Cooperative Oncology Group Performance Status Rating (ECOG-PSR) and the Hospital Anxiety and Depression Scale (HADS) once, 20 consecutive patients treated between February 2001 and October 2001 completed the questionnaires twice, once before surgery and at 2 months follow-up. The FACT-V scores were compared by patients' performance status, FIGO stage, recurrence, and age, and correlated to the HADS scores. Changes in the FACT-V from baseline to 2 months follow-up were evaluated to establish FACT-V's responsiveness to change. RESULTS: The FACT-V's internal consistency was adequate (Chronbach's alpha range, 0.75 to 0.92). Patients with lower performance status, higher FIGO-stage or recurrent disease received lower FACT-V scores, indicating discriminant validity. The correlation between the FACT-V and the HADS were in the expected direction, indicating convergent and divergent validity. From pre- to post-surgery, scores in nine out of fifteen items of the vulvar cancer-specific subscale improved, while those of five items declined, indicating sensitivity of the vulvar cancer specific items to changes in patients' well-being. CONCLUSIONS: The newly developed FACT-V provides a reliable and valid assessment of the quality of life of women with vulvar cancer. It can be used as a short measure of quality of life within research studies, and to facilitate communication about quality of life issues in clinical practice.

Early hepatic stellate cell activation predicts severe hepatitis C recurrence after liver transplantation.

Only a subset of hepatitis C virus (HCV)-infected patients develop progressive hepatic fibrosis after liver transplantation (LT). Hepatic stellate cell (HSC) activation is a pivotal step in hepatic fibrosis and precedes clinically apparent fibrosis. We determined whether early HSC activation, measured in 4-month protocol post-LT biopsies, is predictive of subsequent development of more histologically severe recurrence of HCV. Early (4 month) post-LT HSC activation, as measured by alpha-smooth muscle actin (alpha-SMA) staining, was determined in liver biopsies from recipients with severe (fibrosis score > or = 2, n = 13) and with mild (fibrosis score of 0, n = 13) recurrence of HCV at one-year post-LT. Immunohistochemical staining for alpha-smooth muscle actin (alpha-SMA) was used to generate HSC activation scores (regional and total). Total HSC activation scores at 4 months were similar in patients with severe and mild HCV recurrence (3.9 +/- 2.0 vs. 2.7 +/- 2.2, P = 0.2). Regional HSC activation, assessed as parenchymal (zones 1, 2, and 3) or mesenchymal (portal tracts and fibrous septa), was different between the study groups, with higher mesenchymal scores predictive of progression. No patients in the mild recurrence group had detectable mesenchymal alpha-SMA staining vs. 46% (6/13) of patients with severe recurrence (P < 0.01). Mesenchymal activation of HSC had a specificity and positive predictive value of 100% for development of progressive fibrosis in liver allografts of patients with hepatitis C. In conclusion, early activation of mesenchymal HSCs is a marker for progressive fibrosis in patients with hepatitis C post-LT and may help select patients who would benefit from HCV or HSC-targeted therapy.

Clinical course in patients seeking primary care for back or neck pain: a prospective 5-year follow-up of outcome and health care consumption with subgroup analysis.

STUDY DESIGN: Prospective follow-up. OBJECTIVE: To describe the 5-year clinical course in a cohort of patients treated for back or neck pain in primary care and compare results with the 1-year outcome both for the whole group and for subgroups. SUMMARY OF BACKGROUND DATA: A randomized study showed a decrease in perceived pain and disability after treatment by chiropractic or physiotherapy, but many reported recurrence or continual pain at the 1-year follow-up. Knowledge of the clinical course over longer follow-up periods is limited. METHODS: A 5-year follow-up questionnaire was sent to 314 individuals. Main outcome measures were pain intensity, Oswestry score, and general health. Recurrence, health care consumption, and other measures were described. RESULTS: Fifty-two percent of respondents reported pain (visual analog scale, >10 mm) and back-related disability (Oswestry, >10%) at the 5-year follow-up. This was similar to 1-year results, and 84% of these were the same individuals. Sixty-three percent reported recurrence or continual pain, and 32% reported health care consumption at the 5-year follow-up. CONCLUSIONS: In a cohort of individuals of working age seeking primary care for nonspecific back or neck pain, it can be expected that about half of the population will report pain and disability at the 5-year follow-up. A significant proportion will report recurrence or continual pain and health care consumption. Pain and disability were associated with recurrence or continual pain and health care consumption. Further analysis is needed to identify additional predictors for 5-year outcome, taking into account 1-year follow-up results. Since many patients will have recurrence or continual pain, health policies and clinical decision models for long-term outcome must allow for these aspects.

Prognostic significance of E-cadherin protein expression in pathological stage I-III endometrial cancer.

PURPOSE: Decreased expression of E-cadherin in endometrial cancer cells is associated with adverse prognostic features. This study aimed to evaluate the prognostic significance of decreased E-cadherin expression in patients with endometrial cancer. EXPERIMENTAL DESIGN: Between 1992 and 1999, 102 endometrial cancer patients with stage I-III disease underwent primary surgery at the University of Chicago. Representative tissue specimens were immunostained with a monoclonal antibody to E-cadherin. A semiquantitative evaluation scale was developed based on the percentage of endometrial cancer cells with membranous E-cadherin staining. Tissue sections were scored as "3" if >75%, "2" if 25-75%, "1" if 5-25%, and "0" if <5% of cells stained. E-Cadherin staining was correlated with overall survival (OS), cause-specific survival (CSS), progression-free survival (PFS), and extrapelvic progression. Multivariate Cox proportional hazards modeling was used to estimate hazard ratios, controlling for clinicopathological characteristics and adjuvant treatment. Median follow-up for the study group was 58.5 months. RESULTS: E-Cadherin staining was scored as 0, 1, 2, and 3 in 29.4%, 18.6%, 26.5%, 25.5% of cases, respectively. E-Cadherin expression was positively correlated with myometrial invasion (Kendall tau: 0.30, P < 0.01), and negatively correlated with grade (Kendall tau: -0.13, P = 0.15) and papillary serous or clear cell histology (Kendall tau: -0.14, P = 0.12). Five-year actuarial OS, CSS, PFS, and extrapelvic recurrence rates for negative (score = 0), heterogeneous (score = 1-2), and positive (score = 3) staining were as follows: OS, 69.2 versus 75.7 versus 81.0% (P = 0.64); CSS, 78.8 versus 91.2 versus 95.5% (P = 0.19); PFS, 69.1 versus 88.6 versus 92.2% (P = 0.079), and extrapelvic progression, 20.8 versus 7.3 versus 4.0% (P = 0.17). On multivariate Cox regression, a higher E-cadherin expression score was associated with decreased overall mortality [hazard ratio (HR), 0.59; 95% confidence interval (CI), 0.34-1.03; P = 0.066), and statistically significant decreases in endometrial cancer mortality (HR, 0.23; 95% CI, 0.055-0.94; P = 0.040), disease progression (HR, 0.28; 95% CI, 0.10-0.77; P = 0.014), and extrapelvic recurrence (HR, 0.24; 95% CI, 0.062-0.97; P = 0.045). CONCLUSIONS: Decreased E-cadherin expression is an independent prognostic factor for disease progression and mortality in pathological stage I-III endometrial cancer. Evaluation of E-cadherin expression may aid in the selection of patients for more aggressive adjuvant therapy.

Quality of life improves with treatment in the Canadian Trial of Atrial Fibrillation.

BACKGROUND: The impact of atrial fibrillation (AF) and its treatment on health-related quality of life (QOL) is not well understood. We assessed QOL in patients with symptomatic AF participating in the Canadian Trial of Atrial Fibrillation. METHODS: Self-report QOL questionnaires including the Short-Form-36 (SF-36), symptom checklist (SCL) and AF Severity Scale (AFSS) were completed at baseline and 3, and 12 months after randomization. RESULTS: The study group was aged 65 +/- 10 years and 59% were male. By design, 50% of patients were randomized to amiodarone (n = 132), 25% to sotalol (n = 66), and 25% to propafenone (n = 66). Most patients had normal left ventricular function (89%). Physical (41.9 +/- 9.3 to 43.7 +/- 9.2, P =.001) and mental health (47.5 +/- 10.5 to 49.0 +/- 9.8, P =.023) summary measures from the SF-36 improved significantly from baseline to 3 months. Arrhythmia symptom frequency and severity (SCL) also improved markedly from baseline to 3 months (symptom frequency 20.4 +/- 9.4 to 16.2 +/- 9.5 and symptom severity 16.7 +/- 8.2 to 12.9 +/- 7.4, both P <.001). QOL improvements were not significantly different among the groups randomized to amiodarone, sotalol, or propafenone. However, patients with no symptomatic recurrences of AF had higher scores at 3 months on measures of global well-being than those with recurrences in the first 3 months (7.4 +/- 1.8 vs 6.9 +/- 1.8, P <.05). There were no significant QOL changes from the 3 to 12 month assessment. CONCLUSION: In patients with symptomatic AF, QOL improves after treatment, independent of the specific drug used for treatment. This is especially true for patients in whom treatment prevents AF recurrence.

Association between peridural scar and recurrent radicular pain after lumbar discectomy: magnetic resonance evaluation. ADCON-L European Study Group.

The purpose of this study was to investigate the presence of any correlation between recurrent radicular pain during the first six months following first surgery for herniated lumbar intervertebral disc and the amount of lumbar peridural fibrosis as defined by MR imaging. 197 patients who underwent first-time single-level unilateral discectomy for lumbar disc herniation were evaluated in a randomized, double-blind, controlled multicenter clinical trial. Clinical assessments, performed by physicians blinded to patient treatment status, were conducted preoperatively and at one and six months postoperatively. The enhanced MR images of the operative site utilized in the analysis were obtained at six months postoperatively. Radicular pain was recorded by the patient using a validated visual analog pain scale in which 0 = no pain and 10 = excruciating pain. The data obtained at the 6 month time point were analyzed for an association between amount of peridural scars as measured by MR imaging and clinical failure as defined by the recurrence of radicular pain. The results showed that the probability of recurrent pain increases when scar score increases. Patients having extensive peridural scar were 3.2 times more likely to experience recurrent radicular pain than those patients with less extensive peridural scarring. In conclusion, this prospective, controlled, randomized, blinded, multicenter study has demonstrated that there is a significant association between the presence of extensive peridural scar and the occurrence of recurrent radicular pain.

Interactions between cytomegalovirus, human herpesvirus-6, and the recurrence of hepatitis C after liver transplantation.

Recurrence of hepatitis C (HCV) following liver transplantation is common. Herpesvirus reactivation following transplant may have an immunomodulatory effect resulting in increased HCV replication. We studied whether cytomegalovirus (CMV) and human herpesvirus-6 (HHV-6) may be associated with HCV recurrence and viral load after transplant. We prospectively followed 66 HCV liver-transplant recipients with serial viral load testing for CMV and HHV-6. Infection and viral load were correlated with the development of biopsy-proven HCV recurrence and HCV viral loads. Histologic recurrence of HCV occurred in 41/66 (62.1%) patients. In the primary analysis, CMV infection and disease, and HHV-6 infection were not associated with HCV recurrence. Peak CMV and HHV-6 viral loads were not significantly different in patients with and without recurrence. No correlation was observed between HCV viral loads at 1 and 3 months post-transplant and peak HHV-6 or CMV viral loads. In a subgroup analysis, HHV-6 infection was associated with the development of more severe recurrence (hepatitis and/or fibrosis score > or = 2) (p = 0.01). Also, fibrosis scores at last follow up were higher in patients with CMV disease (1.67 vs. 0.56; p = 0.016) and in patients with HHV-6 infection (1.18 vs. 0.55; p = 0.031). In conclusion, HHV-6 and CMV infection and viral load were not associated with increased overall rates of HCV recurrence or HCV viral load after liver transplantation but may be associated with more severe forms of recurrence.

Overexpression of phosphorylated nuclear factor-kappa B in tonsillar squamous cell carcinoma and high-grade dysplasia is associated with poor prognosis.

Intracellular signals along the epidermal growth factor receptor (EGFR)-Akt-nuclear factor-kappa B (NF-kappaB) pathway have been associated with carcinogenesis in various malignant neoplasms. This investigation was to evaluate the expression of EGFR, phosphorylated(p)-Akt and p-NF-kappaB and correlate them with clinical outcomes in patients with squamous cell carcinoma of the tonsil. A total of 45 patients with squamous cell carcinoma of the tonsil were studied by immunohistochemistry to evaluate the expression levels of EGFR, p-Akt and p-NF-kappaB. Results for squamous cell carcinoma of the tonsil were compared with those for associated high-grade dysplasia and adjacent normal appearing epithelium, when present. In addition, tonsillar epithelium from non-neoplastic specimens of age-matched patients also was stained for the same markers. High-grade dysplasia and squamous cell carcinoma of the tonsil demonstrated a similar pattern of expression, which differed from the pattern seen in the adjacent normal epithelium and tonsillar epithelium from normal controls (an overexpression for each of these three protein analytes in high-grade dysplasia and squamous cell carcinoma of the tonsil as demonstrated by immunohistochemistry). When markers from squamous cell carcinoma of the tonsil were correlated with survival status, only increasing levels of p-NF-kappaB immunoreactivity (a relative overexpression) were statistically significant predictors of poor survival. No markers in squamous cell carcinoma of the tonsil were significantly related to rate of recurrence. When analyzing marker scores from tissue with high-grade dysplasia, relative overexpressions of both p-Akt and p-NF-kappaB were significantly related to poor survival. Additionally, increasing levels of p-NF-kappaB immunopositivity from tissue with high-grade dysplasia were also significantly related to rate of recurrence. In summary, p-NF-kappaB, overexpressed in high-grade dysplasia and squamous cell carcinoma of the tonsil, is associated with worse prognosis in terms of high recurrence and poor survival, respectively. This significant finding in patients with squamous cell carcinoma of the tonsil, in combination with previous animal and in vitro studies, suggests that p-NF-kappaB represents a potential therapeutic target in head and neck squamous cell carcinoma.

Results of perineal procedures for the treatment of rectal prolapse.

The optimal surgical procedure for the management of rectal prolapse is still under debate. Therefore, the aim of this study was to evaluate the short-term outcome of perineal procedures in patients with rectal prolapse. Between April 1989 and April 1995, all consecutive patients at the Cleveland Clinic Florida who underwent Delorme's procedure or perineal rectosigmoidectomy with or without levatoroplasty for full-thickness rectal prolapse were evaluated. Clinical and physiological assessments were performed before and after surgery. A standard continence scoring system, based on the frequency and type of incontinence (0 = full continence, 20 = complete incontinence) was used to assess the results of each procedure. Additionally, morbidity and mortality, and clinical and functional outcomes were evaluated. Sixty-one patients underwent perineal procedures for rectal prolapse; 16 patients died from comorbid conditions after undergoing postoperative physiologic assessment. These 55 females and 6 males, with a mean age of 75 (range, 48-101) years were studied. Patients were followed up for 27.2 (6-72) months, and mean prolapse duration was 4.2 (0.2-30) years. Although mean preoperative incontinence score was 15.9 (8-20), it was 6.3 (range, 0-12) in postoperative course. Mean resection length of rectosigmoid was 23.3 (3-71) cm, and in these patients, two (3.3%) coloanal anastomotic leaks and four (6.5%) anastomotic strictures were observed. There was one postoperative death. There were statistically significant differences among the groups relative to short-term recurrence rates, postoperative incontinence scores, mean resection length, coloanal anastomotic stricture, and leak (P< 0.001). However, pre- and postoperative anal manometry did not reveal statistically significant changes (P > 0.05) in each group or among the groups. Perineal procedures were found to be safe and effective in eradicating rectal prolapse and improving fecal incontinence in the elderly.

Full-mouth ultrasonic debridement and risk of disease recurrence: a 1-year follow-up.

AIM: To evaluate the incidence of disease recurrence following a full-mouth pocket/root debridement approach with ultrasonic instrumentation versus that following a traditional approach of quadrant-wise scaling and root planing (Q-SRP) performed with hand instrumentation. METHODS: Thirty-seven patients were re-examined 1 year after the completion of a 6-month clinical trial comparing two different treatment protocols: a 1-h session of full-mouth ultrasonic debridement (UD--19 patients) or four sessions of Q-SRP with hand instruments (Q-SRP--18 patients). At 3 months, re-instrumentation was performed of pockets showing a remaining probing pocket depth (PPD) of > or =5 mm using the same type of instruments as used during the initial treatment phase. The clinical examinations comprised assessments of plaque, bleeding on probing (BoP) and PPD. The primary outcome variable was the incidence of recurrent diseased sites (i.e., sites showing PPD > or =5 mm and BoP+) between the post-treatment and 1-year follow-up examinations. All sites that were healed (PPD < or =4 mm and BoP(-)) at the post-treatment examination were included in the study sample, with a mean number of sites per patient of 23.5. RESULTS: In the UD group, 29 (7%) out of 430 initially healed sites showed disease recurrence at the 1-year follow-up examination compared with 47 (11%) of 440 sites in the Q-SRP group (p>0.05). Twelve patients (63%) in the UD group presented recurrent diseased pockets, compared with 14 patients (78%) in the Q-SRP group. Two or more recurrent, diseased pockets were observed in nine patients in the UD group versus 11 in the Q-SRP group. All but one of the smokers belonged to the group of patients presenting recurrences. A tendency towards a higher mean plaque score was observed for the patients with recurrent sites. CONCLUSION: The study revealed no significant difference in the incidence of recurrence of diseased periodontal pockets between the full-mouth UD approach and the traditional approach of Q-SRP.

Radical prostatectomy and postoperative irradiation in patients with pathological stage C (T3) carcinoma of the prostate.

PURPOSE: Adenocarcinoma of the prostate is the most common human cancer of internal organs. Radical surgery is regarded by many to be the treatment of choice for capsule confined disease. Since accurate preoperative assessment of tumor stage is difficult to define, many patients are subsequently found to have pathological stage C (T3) disease. These patients should be considered for adjuvant radiotherapy. METHODS AND MATERIALS: A group of 201 PS C (T3) unselected patients, treated with radical prostatectomy and limited pelvic lymphadenectomy, received postoperative irradiation to the prostate bed. This radiotherapy was given between 42-90 days after surgery and consisted of a median dose of 48 Gy. Patient survival, disease free survival, time to clinical and chemical relapse and the incidence of local and systemic relapse were analyzed. The influence of multiple parameters on the treatment outcome including patient age, treatment period, clinical stage, pathological stage, Gleason's score, prostate specific antigen (PSA), radiotherapy techniques and radiation dose were examined using univariate and multivariate analysis. Follow-up ranged from 3 to 15 years, with a median of 5 years. RESULTS: The overall 5- and 10-year actuarial survival was 92% and 83% (median > 10 years), respectively and the 5- and 10-year disease-free survival (clinical and PSA) was 67% and 53% (median > 10 years), respectively. A total of 61 (30%) patients had a recurrence, including 23 (11%) patients who had clinical and 38 (19%) who had PSA recurrence. Of the 23 patients with clinical recurrence, 10 (5%) had local recurrence, including two patients who had local and systemic recurrence. Pathological stage and Gleason's score were independently predictive of recurrence (each with p < 0.001 after controlling for the other). Patients in the worst prognostic category with pathological stage C3 and Gleason's score 8-10 were predicted to be at 7.2 times the risk of recurrence, compared to stage C1 or C2 and Gleason's score 2-7 patients. Preoperative PSA level (> 25 ng/ml) was also an important independent factor predicting tumor recurrence, p = 0.05. All other investigated parameters were not significant in predicting tumor recurrence. This treatment program was very well tolerated by the study patients, with seven (3.5%) recorded with major and 18 (9%) with minor surgical complications, while 65% of patients had minor and clinically insignificant radiation complications. CONCLUSION: Surgery followed by moderate dose radiotherapy in patients with PS C (T3) prostatic carcinoma was well tolerated and resulted in excellent overall and disease free survival, with a low incidence of local recurrence. New treatment strategies need to be developed for patients with C3 tumors and those with high (8-10) Gleason's score and those with high (> 25 ng/ml) PSA level at diagnosis.

The role of thallium-201 whole body scan with pelvic SPECT in patients with uterine cervical cancer treated by radiation therapy: a preliminary report.

Evaluation of tumor extent before treatment and its response to therapy is important. The aim of this report is to assess the usefulness with thallium-201 (Tl-201) imaging study including whole body scan and pelvic single photon emission computed tomography (SPECT) in patients with uterine cervical cancers treated by radiation therapy. Before irradiation, eleven patients received detailed physical examination and Tl-201 imaging studies. A 4-score grading system was set for evaluation. The interval between Tl-201 imaging follow-up and completion of radiotherapy is one to four months, and its findings were compared with those from CT scan and clinical evidence. Before radiation, left supraclavicular and paraaortic lymphadenopathy was identified in one patient from whole body scan. Accumulation of Tl-201 uptake is observed from pelvic SPECT in all patients. It seems that patients with more tumor bulk had more intense uptake, except for one case with history of suspected pelvic inflammatory disease (PID). After radiotherapy, complete or partial regression is observed. For 6 patients with complete regression (score = 0), no evidence of recurrence is confirmed by follow-up examinations. For three patients with little residual uptake (score = 1), one is suspected with residual density and she is under close follow-up, the other two patients seem due to uterine myoma or short latency. These three patients received another Tl-201 scan 6 months after irradiation completion and the score became zero. One patient with residual intense uptake (score = 2) suffered from relapse in the pelvis and abdomen. This preliminary report indicates that Tl-201 whole body scan and pelvic SPECT has potential in the assessment of response to radiotherapy in patients with uterine cervical cancers. However, further studies including more cases and longer follow-up are needed.

Effect of cerebrovascular risk factors on depression treatment outcome in later life.

OBJECTIVE: The vascular depression hypothesis posits that depression can arise in late life from cerebrovascular damage and that depression arising this way has a different clinical presentation and is more chronic and treatment-resistant than early-onset depression. This study tested the relationship of cerebrovascular risk factors (CVRF) to clinical presentation and treatment outcome in 156 subjects enrolled in a long-term maintenance treatment study of late-life recurrent major depression. METHODS: CVRF scores were generated with the Probability of Stroke Risk Profile. Subjects with the highest one-third of scores were designated High CVRF, and their baseline clinical presentation and treatment outcomes were compared with the remaining subjects. RESULTS: In the High-CVRF group, a greater proportion of subjects had first-onset depression after age 60. However, high CVRF score, late onset of depression, and their interaction had no effect on time-to-remission, need for adjunctive medication, or increased risk for recurrence during 3-year follow-up. Furthermore, high CVRF score and late onset of depression did not predict the associated clinical features of vascular depression, such as psychomotor retardation and lack of insight, previously described in the literature. CONCLUSION: Optimism about the outcome of late-life depression treatment should not be diminished by the presence of high cerebrovascular risk.

The relationship between gastric-oral Helicobacter pylori and oral hygiene in patients with vitamin B12-deficiency anemia.

OBJECTIVE: The aim of this study was to determine whether a relationship exists between gastric and oral Helicobacter pylori and oral hygiene in patients with vitamin B12 deficiency. STUDY DESIGN: One hundred eight patients with vitamin B12 deficiency who were H pylori -positive in their gastric mucosa were enrolled in the study. These patients were divided into 3 groups determined by Oral Hygiene Index (OHI) scores of good, fair, or poor. H pylori was detected in the dental plaque with camphylobacter-like organism test gels. All patients were treated with a combination regimen to eradicate H pylori. RESULTS: H pylori positivity in dental plaque was correlated with OHI scores; the positivity was 28.5%, 90.2%, or 100% in patients with good, fair, or poor OHI scores, respectively. The eradication of H pylori was associated with recovery from anemia and increased serum vitamin B12 level (P <.0001 and P <.0001). The patients with poor OHI scores had the most frequent gastric recurrence of H pylori (58.3%) compared with those with fair OHI scores (41.2%) and good OHI scores (4.8%). CONCLUSIONS: H pylori seems to be an etiologic factor in vitamin B12 deficiency, since anemia was cured and the level of vitamin B12 in the serum increased as a result of its eradication. However, eradication of H pylori from gastric mucosa alone is not enough to prevent gastric recurrence of the bacteria. Proper oral hygiene must be established to eliminate H pylori in dental plaque. Therefore, we suggest that control of H pylori in dental plaque is necessary to control recurrence of H pylori.

Long-term use of combined radiation therapy and hormonal therapy in the management of stage D1 prostate cancer.

PURPOSE: To determine tumor response, patterns of relapse, and prognostic indicators in patients followed long-term after combined hormonal radiation therapy of adenocarcinoma of the prostate in men with tumor metastatic to pelvic lymph nodes. METHODS AND MATERIALS: Seventy-nine patients with adenocarcinoma of the prostate with pathologically confirmed pelvic lymph node metastases were treated with combined radiation therapy and hormonal therapy. Of these, 55 patients (70%) had T3 disease, with the remainder having earlier-stage disease; 45 (57%) patients had N2 disease (Whitmore-Jewett staging). No distant metastases were detected at initial staging, and no patient had radiographic or pathologic involvement of the para-aortic nodes. Pelvic lymph nodes were irradiated to a dose 45-54 Gy, and the prostate was irradiated to a dose 65-71.8 Gy. Hormonal therapy began up to 2 months before radiation and continued indefinitely. Patients were allowed to select their hormonal therapy and could choose diethylstilbestrol (DES) (2 patients), orchiectomy (21 patients), luteinizing hormone-releasing hormone agonist (12 patients), or combined androgen blockade (44 patients). Prognostic factors examined included microscopic vs. measurable lymph node involvement, one-sided vs. two-sided disease, T stage, pretreatment PSA, method of androgen blockade, and Gleason score. Log-rank analysis was used to determine statistical significance with respect to overall survival, disease-free survival, clinical freedom from progression, and biochemical freedom from progression; Cox multivariate analysis was employed to determine potential confounders. RESULTS: Median follow-up was 6.7 years. There were 25 recurrences among the 79 patients, including 7 biochemical recurrences without clinical evidence of disease, three local recurrences in the prostate, and distant metastases in 14 patients; 2 patients were deceased, with cause of death listed as prostate cancer, though the location of recurrence was unknown. Patients with biochemical failure before 5 years were more likely to fail distantly, 16% vs. 4% (p < 0.001). Overall actuarial survival at 5, 8, and 12 years was 86%, 72%, and 53%, respectively, whereas actuarial disease-free survival was 90%, 87%, and 81%. Ten patients died of intercurrent disease; these included 4 patients who died of a separate (nonpelvic) malignancy of nonadenocarcinomatous histology with no elevation in PSA. When the potential prognostic variables were examined, a trend toward increased biochemical recurrence in patients with Gleason score >or=8 was observed; this became statistically significant when the 4 patients with known residual lymph node disease after biopsy were excluded (p < 0.03). Gleason score remained the only significant indicator on multivariate analysis. A single long-term toxic event, recto-ureteral fistula, was observed. CONCLUSION: Combined hormonal and radiation therapy continues to represent an effective treatment option for patients with adenocarcinoma of the prostate with metastasis confined to pelvic lymph nodes. All patient groups seem to have a better disease-free survival than that reported previously in single-modality hormone or radiation treatment series. There is a suggestion that patients with lower Gleason score have a lower risk for recurrence. Combined modality therapy may also extend disease-free survival and allow patients to maintain independent function.
