Effects of the body mass index on menopausal symptoms among Asian American midlife women using two different classification systems

OBJECTIVE

To explore the effects of the body mass index (BMI) on menopausal symptoms among Asian American midlife women using two different classification systems: the international classification and the BMI classification for public health action among Asian populations.

DESIGN

Secondary analysis using data from two large Internet survey studies.

SETTING

Communities and groups of midlife women on the Internet.

PARTICIPANTS

A total of 223 Asian American midlife women who were recruited over the Internet.

METHODS

The Midlife Women's Symptom Index and self-reports of height and weight were used to collect data. The data were analyzed using multiple analyses of covariance.

RESULTS

No significant differences in the prevalence and severity scores among three subscales and total menopausal symptoms according to the international classification were found. When the BMI classification for public health action among Asian populations was used as an independent variable, significant differences were found in the severity scores of three subscales and total menopausal symptoms. Results of the post-hoc analyses showed that Asian American midlife women who were in the BMI classification for high risk had significantly more severe menopausal symptoms than those who were in the BMI classification for increased risk.

CONCLUSION

For Asian American women, BMI categorized using the BMI classification for Asian populations is more closely related to the severity of menopausal symptoms than BMI categorized using the international classification. Nurses need to consider the BMI classification for Asian populations when they develop interventions to prevent and alleviate menopausal symptoms among Asian American midlife women.

Validation of the Edmonton Symptom Assessment System in Korean patients with cancer

CONTEXT

The Edmonton Symptom Assessment System (ESAS) is a brief, widely adopted, multidimensional questionnaire to evaluate patient-reported symptoms.

OBJECTIVES

To develop a Korean version of the ESAS (K-ESAS) and to perform a psychometric analysis in Korean patients with advanced cancer.

METHODS

We tested the K-ESAS in two pilot studies with 15 patients each. We assessed internal consistency, test-retest reliability, and concurrent validity in 163 Korean patients, who completed the K-ESAS along with the Korean versions of the M. D. Anderson Symptom Inventory (K-MDASI) and the Hospital Anxiety and Depression Scale (K-HADS) twice. A total of 38 patients completed the questionnaires again seven days later to assess responsiveness.

RESULTS

The K-ESAS scores had good internal consistency, with a Cronbach's alpha coefficient of 0.88, indicating that no questions had undue influence on the score. Pearson correlation coefficients for K-ESAS symptom scores between baseline and after two to four hours ranged from 0.72 (95% CI 0.64-0.79) to 0.87 (95% CI 0.82-0.90), indicating strong test-retest reliability. For concurrent validity, Pearson correlation coefficients between K-ESAS symptom scores and corresponding K-MDASI symptom scores ranged from 0.70 (95% CI 0.62-0.77) to 0.83 (95% CI 0.77-0.87), indicating good concurrent validity. For the K-HADS, concurrent validity was good for anxiety (r=0.73, 95% CI 0.65-0.79) but moderate for depression (r=0.4, 95% CI 0.26-0.52). For responsiveness, changes in K-ESAS scores after seven days were moderately correlated with changes in K-MDASI scores but weakly correlated with changes in K-HADS scores.

CONCLUSION

The K-ESAS is a valid and reliable tool for measuring multidimensional symptoms in Korean patients with cancer.

Creating computable algorithms for symptom management in an outpatient thoracic oncology setting

CONTEXT

Adequate symptom management is essential to ensure quality cancer care, but symptom management is not always evidence based. Adapting and automating national guidelines for use at the point of care may enhance use by clinicians.

OBJECTIVES

This article reports on a process of adapting research evidence for use in a clinical decision support system that provided individualized symptom management recommendations to clinicians at the point of care.

METHODS

Using a modified ADAPTE process, panels of local experts adapted national guidelines and integrated research evidence to create computable algorithms with explicit recommendations for management of the most common symptoms (pain, fatigue, dyspnea, depression, and anxiety) associated with lung cancer.

RESULTS

Small multidisciplinary groups and a consensus panel, using a nominal group technique, modified and subsequently approved computable algorithms for fatigue, dyspnea, moderate pain, severe pain, depression, and anxiety. The approved algorithms represented the consensus of multidisciplinary clinicians on pharmacological and behavioral interventions tailored to the patient's age, comorbidities, laboratory values, current medications, and patient-reported symptom severity. Algorithms also were reconciled with one another to enable simultaneous management of several symptoms.

CONCLUSION

A modified ADAPTE process and nominal group technique enabled the development and approval of locally adapted computable algorithms for individualized symptom management in patients with lung cancer. The process was more complex and required more time and resources than initially anticipated, but it resulted in computable algorithms that represented the consensus of many experts.

Capturing the patient's experience: using qualitative methods to develop a measure of patient-reported symptom burden: an example from ovarian cancer

CONTEXT

Experts in patient-reported outcome (PRO) measurement emphasize the importance of including patient input in the development of PRO measures. Although best methods for acquiring this input are not yet identified, patient input early in instrument development ensures that instrument content captures information most important and relevant to patients in understandable terms.

OBJECTIVES

The M. D. Anderson Symptom Inventory (MDASI) is a reliable valid PRO instrument for assessing cancer symptom burden. We report a qualitative (open-ended, in-depth) interviewing method that can be used to incorporate patient input into PRO symptom measure development, with our experience in constructing an MDASI module for ovarian cancer (MDASI-OC) as a model.

METHODS

Fourteen patients with ovarian cancer (OC) described symptoms experienced at the time of the study, at diagnosis, and during prior treatments. Researchers and clinicians used content analysis of interview transcripts to identify symptoms in patient language. Symptoms were ranked on the basis of the number of patients mentioning them and by clinician assessment of relevance.

RESULTS

Forty-two symptoms were mentioned. Eight OC-specific items will be added to the 13 core symptom items and six interference items of the MDASI in a test version of the MDASI-OC on the basis of the number of patients mentioning them and clinician assessment of importance. The test version is undergoing psychometric evaluation.

CONCLUSION

The qualitative interviewing process, used to develop the test MDASI-OC, systematically captures common symptoms important to patients with OC. This methodology incorporates the patient experience recommended by experts in PRO instrument development.

Beyond intuition: patient fever symptom experience

CONTEXT

Fever is an important sign of inflammation recognized by health care practitioners and family caregivers. However, few empirical data obtained directly from patients exist to support many of the long-standing assumptions about the symptoms of fever. Many of the literature-cited symptoms, including chills, diaphoresis, and malaise, have limited scientific bases, yet they often represent a major justification for antipyretic administration.

OBJECTIVES

To describe the patient experience of fever symptoms for the preliminary development of a fever assessment questionnaire.

METHODS

Qualitative interviews were conducted with 28 inpatients, the majority (86%) with cancer diagnoses, who had a recorded temperature of ≥38°C within approximately 12 hours before the interview. A semi-structured interview guide was used to elicit patient fever experiences. Thematic analyses were conducted by three independent research team members, and the data were verified through two rounds of consensus building.

RESULTS

Eleven themes emerged. The participants reported experiences of feeling cold, weakness, warmth, sweating, nonspecific bodily sensations, gastrointestinal symptoms, headaches, emotional changes, achiness, respiratory symptoms, and vivid dreams/hallucinations.

CONCLUSION

Our data not only confirm long-standing symptoms of fever but also suggest new symptoms and a level of variability and complexity not captured by the existing fever literature. Greater knowledge of patients' fever experiences will guide more accurate assessment of symptoms associated with fever and the impact of antipyretic treatments on patient symptoms in this common condition. Results from this study are contributing to the content validity of a future instrument that will evaluate patient outcomes related to fever interventions.

[Clinical assessment cannot predict if children are infected with Mycoplasma pneumoniae]

This meta-analysis was carried out to detect if clinical signs can predict infection with Mycoplasma pneumoniae in children. The only significant finding was that absence of wheezing was associated with M. pneumoniae-infection. The analysis does not justify changes in the recommendation regarding treatment of pneumonia in children. Empiric therapy with macrolides can only be recommended if the patient does not tolerate betalactam.

Prospective evaluation of a new visual prostate symptom score, the international prostate symptom score, and uroflowmetry in men with urethral stricture disease

OBJECTIVE

To evaluate the correlation between the visual prostate symptom score (VPSS) and the international prostate symptom score (IPSS) and uroflowmetry parameters in men with urethral stricture disease. The VPSS offers a nonverbal, pictographic assessment of lower urinary tract symptoms.

METHODS

A total of 100 men followed up with a diagnosis of urethral stricture were evaluated from March 2011 to November 2012 with IPSS, VPSS, uroflowmetry, urethral calibration, and urethrography. Follow-up every 3 months for 3-18 months was available in 78 men for a total of 289 visits. Procedures performed were urethral dilation in 105, internal urethrotomy in 54, and urethroplasty in 8 patients. Statistical analysis was performed with Spearman's rank correlation, Fisher's exact, and Student t tests.

RESULTS

The time taken to complete the VPSS vs IPSS was significantly shorter (118 vs 215 seconds at the first and 80 vs 156 seconds at follow-up visits; P <.001). There were significant correlations between the VPSS and IPSS (r = 0.845; P <.001), maximum urinary flow rate (Qmax; r = 0.681; P <.001) and urethral diameter (r = -0.552; P <.001). A combination of VPSS >8 and Qmax <15 mL/s had positive and negative predictive values of 87% and 89%, respectively, for the presence of urethral stricture.

CONCLUSION

The VPSS correlates significantly with the IPSS, Qmax, and urethral diameter in men with urethral stricture disease and takes significantly less time to complete. A combination of VPSS >8 and Qmax <15 mL/s can be used to avoid further invasive evaluation during follow-up in men with urethral strictures.

Symptom burden predicts nursing home admissions among older adults

CONTEXT

Symptom burden has been associated with functional decline in community-dwelling older adults and may be responsive to interventions. Known predictors of nursing home (NH) admission are often nonmodifiable.

OBJECTIVES

To determine if symptom burden independently predicted NH admission among community-dwelling older adults over an eight and a half-year follow-up period.

METHODS

A random sample of community-dwelling Medicare beneficiaries in Alabama, stratified by race, gender, and rural/urban residence had baseline in-home assessments of sociodemographic measurements, Charlson comorbidity count, and symptoms. Symptom burden was derived from a count of 10 patient-reported symptoms. Nursing home admissions were determined from telephone interviews conducted every six months over the eight and a half years of study. Cox proportional hazard modeling was used to examine the significance of symptom burden as a predictor for NH admission after adjusting for other variables.

RESULTS

The mean ± SD age of the sample (N = 999) was 75.3 ± 6.7 years, and the sample was 51% rural, 50% African American, and 50% male. Thirty-eight percent (n = 380) had symptom burden scores ≥2. Seventy-five participants (7.5%) had confirmed dates for NH admission during the eight and a half years of follow-up. Using Cox proportional hazard modeling, symptom burden remained an independent predictor of time to NH placement (hazard ratio = 1.11; P = 0.02), even after adjustment for comorbidity count, race, sex, and age.

CONCLUSION

Symptom burden is an independent risk factor for NH admission. Aggressive management of symptoms in older adults may reduce or delay NH admission.

Factors associated with depression in disease-free stomach cancer survivors

CONTEXT

Depression in cancer survivors affects the rest of their lives in many ways.

OBJECTIVES

To estimate the prevalence of depression and identify associated factors in disease-free stomach cancer survivors.

METHODS

We enrolled 391 stomach cancer survivors who had been disease-free for at least one year after surgery from the cancer registries of two hospitals in Korea. Stomach cancer survivors were mailed a survey that included the Beck Depression Inventory, the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30, and the associated stomach module, the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Stomach Cancer Module 22.

RESULTS

Forty-four percent of survivors suffered from depression, and more women (49%) than men (42%) had high depression scores (Beck Depression Inventory >13). In multiple logistic regression analysis, lower income (odds ratio [OR] 2.49; 95% CI 1.64-3.78), problems with care before treatment (OR 1.92; 95% CI 1.23-2.98), body image change (OR 2.23; 95% CI 1.41-3.53), and symptoms of fatigue (OR 3.11; 95% CI 1.49-6.52), dyspnea (OR 2.57; 95% CI 1.48-4.45), or insomnia (OR 4.51; 95% CI 1.88-10.83) were associated with depression.

CONCLUSION

The prevalence of depression was high in stomach cancer survivors even after the completion of treatment, especially among those with problems amenable to treatment, and we identified the associated factors. We suggest that stomach cancer survivors should be screened for depression after the end of treatment.

Primary pulmonary diffuse large B-cell non-Hodgkin's lymphoma in a child

A 3-year-old girl presented with a history of intermittent fever of six months duration associated with respiratory symptoms consisting of recurrent cough, fever, wheeze and a suspected history of contact with tuberculosis (TB). Chest radiograph revealed pulmonary infiltrates mimicking miliary TB. She was started on anti-tuberculous treatment, but in view of clinical deterioration, a further work-up including a lung biopsy revealed non-Hodgkin's lymphoma (NHL). This case documents the extremely rare occurrence of pulmonary involvement and miliary infiltrates on the chest radiograph in NHL.

Functional impairments as symptoms in the symptom cluster analysis of patients newly diagnosed with advanced cancer

CONTEXT

Symptoms and subsequent functional impairment have been associated with the biological processes of disease, including the interaction between disease and treatment in a measurement model of symptoms. However, hitherto cluster analysis has primarily focused on symptoms.

OBJECTIVES

This study among patients within 100 days of diagnosis with advanced cancer explored whether self-reported physical symptoms and functional impairments formed clusters at the time of diagnosis.

METHODS

We applied cluster analysis to self-reported symptoms and activities of daily living of 111 patients newly diagnosed with advanced gastrointestinal (GI), gynecological, head and neck, and lung cancers. Based on content expert evaluations, the best techniques and variables were identified, yielding the best solution.

RESULTS

The best cluster solution used a K-means algorithm and cosine similarity and yielded five clusters of physical as well as emotional symptoms and functional impairments. Cancer site formed the predominant organizing principle of composition for each cluster. The top five symptoms and functional impairments in each cluster were Cluster 1 (GI): outlook, insomnia, appearance, concentration, and eating/feeding; Cluster 2 (GI): appetite, bowel, insomnia, eating/feeding, and appearance; Cluster 3 (gynecological): nausea, insomnia, eating/feeding, concentration, and pain; Cluster 4 (head and neck): dressing, eating/feeding, bathing, toileting, and walking; and Cluster 5 (lung): cough, walking, eating/feeding, breathing, and insomnia.

CONCLUSION

Functional impairments in patients newly diagnosed with late-stage cancers behave as symptoms during the diagnostic phase. Health care providers need to expand their assessments to include both symptoms and functional impairments. Early recognition of functional changes may accelerate diagnosis at an earlier cancer stage.

Comparing two approaches for studying symptom clusters: factor analysis and structural equation modeling

PURPOSE

We investigated alternative ways of understanding the relationships among co-occurring symptoms in individuals with advanced cancer. While factor analysis has been increasingly used to identify symptom clusters, we argue that structural equation modeling is more appropriate because it permits investigating and testing of a greater variety of potential causal interconnections among symptoms.

METHODS

The sample included 82 palliative patients whose symptom scores were obtained from a database of the Capital Health Regional Palliative Care Program in Alberta, Canada, from 1995 to 2000. Data were analyzed using exploratory factor analysis (SPSS PASW 18.0.0, 2009) and compared to previous results obtained using structural equation modeling (LISREL 8.8, 2009).

RESULTS

Factor models failed to fit the covariance data, even though a single factor "explained" nearly half the variance. Structural equation models fit the data and explained an average of 66 % of the variance in the dependent latent variables. The factor analytic estimates were not clinically useful because they failed to correspond to the reasonable underlying common causes of the symptoms. Structural equation models, on the other hand, incorporated and tested specific clinically anticipated causal relationships among the symptoms and changes in those symptoms over time.

CONCLUSION

We used factor analysis to reanalyze data previously investigated with structural equation modeling and found that the structural equation models fit the data better and were more interpretable from a clinical perspective. We caution that factor models should be tested for consistency with the data and critically examined for inconsistencies with clinical understandings of the causal foundations of coordinated symptoms.

The diagnosis and management of lower urinary tract symptoms in multiple sclerosis patients

Sixty-five percent of multiple sclerosis patients have moderate to severe urinary symptoms and up to 14% initially present with urinary symptomatology. Urinary retention, neurogenic detrusor overactivity, and detrusor sphincter dyssynergia, all increase the risk for urinary tract infections in patients with multiple sclerosis, and these infections may exacerbate their immune response, leading to symptom progression. Fewer than half of the patients with urinary symptoms have seen a specialist and only half have been treated for their neurogenic detrusor overactivity. Several treatments including pelvic floor muscle therapy, pelvic floor electrical stimulation, anticholinergics, desmopressin, sacral nerve neuromodulation, posterior tibial nerve stimulation, cannabinoids, and intravesical therapy with vanniloids, as well as botulinum toxin, have all been shown to be effective in treating urinary symptoms in those with multiple sclerosis. Clean intermittent catheterization is invaluable in patients with persistent urinary retention to avoid infection and upper tract dysfunction. Indwelling transurethral catheterization should be avoided because of the high risk of infection. Identification and successful treatment of these urinary conditions will improve the health and quality of life for these men and women.

[Rare infection--prolonged A. naeslundii bacteremia caused by severe caries]

Actinomyces is an anaerobic, gram positive, rod shape bacteria that doesn't create spores. Actinomyces is part of the mouth, intestines, vagina and upper respiratory system flora. The infection appears mostly on the face, neck, abdomen and pelvis in cases of mucosa injury and most common in immunosuppressed patients. The spread of Actinomyces through the blood system is rare. In this article we present a 9 year old male patient with no history of diseases who was diagnosed with prolonged bacteremia of A. naeslundii without specific infection excluding severe caries. Characterization of bacteria from the blood culture was performed by molecular biology and the patient was treated with Ampicillin and tooth extraction that led to the disappearance of the bacteremia.

Validity and reliability of the Swedish version of the Memorial Symptom Assessment Scale (MSAS): an instrument for the evaluation of symptom prevalence, characteristics, and distress

CONTEXT

There are few scales in Swedish that assess symptoms in the dimensions of frequency, severity, and distress.

OBJECTIVES

The purpose of this study was to translate and determine the validity and reliability of the Memorial Symptom Assessment Scale (MSAS) in a Swedish population of postmenopausal women newly diagnosed with primary or recurrent breast cancer.

METHODS

The original 32-item MSAS, a self-report measure for assessing symptom distress and frequency in cancer patients, was translated and administered to 206 patients (primary, n = 150 and recurrent, n = 56).

RESULTS

The MSAS psychological symptom subscale correlated with the emotional and cognitive functioning subscales of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), and showed the highest correlation with the EORTC QLQ-C30 emotional functioning subscale (r = -0.78; P < 0.01). The psychological symptom subscale also correlated with the Hospital Anxiety and Depression Scale (HADS) within values for anxiety (r = 0.68; P < 0.01) and with the EORTC QLQ-C30 within cognitive functioning values (r = -0.58; P < 0.01). The Global Distress Index (GDI)-MSAS showed satisfactory correlations with the EORTC QLQ-C30 emotional functioning subscale (r = -0.75; P < 0.01), whereas the correlation between the GDI-MSAS and the EORTC QLQ-C30 cognitive functioning subscale was somewhat lower (r = -0.54; P < 0.01). Correlations between the GDI-MSAS and the HADS anxiety subscale were confirmed (r = 0.62; P < 0.01), and a correlation between the MSAS physical symptom items and symptom items in the EORTC-QLQ-C30 was evident (r = 0.60-0.85; P < 0.01). Cronbach's alpha coefficients for the MSAS and MSAS subscales based on symptom scores ranged from 0.80 to 0.89. The internal consistency at different time points was satisfactory, ranging from 0.86 (baseline) to 0.90 (follow-up).

CONCLUSION

The Swedish version of the MSAS presents as a valid and reliable measure for assessing symptom distress, severity, and frequency in Swedish patients diagnosed with primary and recurrent breast cancer.

Evaluation of treatment- and disease-related symptoms in advanced head and neck cancer: validation of the national comprehensive cancer network-functional assessment of cancer therapy-head and neck cancer symptom index-22 (NFHNSI-22)

CONTEXT

The Functional Assessment of Cancer Therapy-Head and Neck is a well-validated assessment of quality of life used with patients diagnosed with head and neck cancers (HCNs). The present study is an attempt to evaluate and modify this instrument as necessary in light of the recent regulatory guidelines from the Food and Drug Administration on the use of patient-reported outcomes in clinical trials.

OBJECTIVES

Overall, the goal was to identify patients' highest priority cancer symptoms, compare these symptoms with those suggested by oncology experts, and construct a brief symptom index to assess these symptoms and categorize them as treatment-related, disease-related, or related to general function and well-being.

METHODS

Patients (N=49) with advanced (Stages III and IV) HCNs were recruited from participating National Comprehensive Cancer Network institutions and community cancer support organizations in the Chicago area. Patients completed open-ended interviews and symptom checklists. Participating oncology physician experts also rated symptoms. Content validity was obtained by evaluating results alongside items in the Functional Assessment of Chronic Illness Therapy system. Eleven oncologists categorized symptoms in terms of importance and also whether the symptoms were primarily related to disease, treatment, or functional well-being.

RESULTS

HCN-related symptoms endorsed as high priority by both patients and oncology experts were selected for the new National Comprehensive Cancer Network-Functional Assessment of Cancer Therapy-Head and Neck Cancer Symptom Index-22. The final version includes 22 items, which are broken down into disease-related symptoms, treatment side effects, or general function and well-being. The new scale has acceptable internal consistency (Cronbach's coefficient alpha=0.86), content validity for use in chemotherapy trials of patients with advanced disease, and concurrent validity as demonstrated by moderate-to-strong correlations with the existing Functional Assessment of Chronic Illness Therapy measure.

CONCLUSION

The National Comprehensive Cancer Network-Functional Assessment of Cancer Therapy-Head and Neck Cancer Symptom Index-22 adequately reflects symptom and side effect concerns of advanced HCN patients as well as oncology physicians. This instrument can be used to evaluate the most important disease-related symptoms, treatment side effects, and function/well-being in patients with advanced HCNs in clinical practice and research.

Appropriateness and reliability testing of the modified Richmond Agitation-Sedation Scale in Spanish patients with advanced cancer

CONTEXT

A tool to quantify agitation severity and sedation level in patients with advanced cancer is needed.

OBJECTIVES

To test the appropriateness and reliability of the Richmond Agitation-Sedation Scale (RASS) in Spanish patients with advanced cancer.

METHODS

The original RASS was translated into Spanish according to the standard guidelines. Face validity was assessed by members of the palliative care team, and interrater reliability was assessed, using a weighted kappa, from observations of patients admitted to the palliative care unit. The association between scores of the RASS, Ramsay Sedation Scale, and Glasgow Coma Scale was evaluated using Spearman's ρ.

RESULTS

Three hundred twenty-two observations were performed in 156 patients: 116 observations were performed for delirious patients, 76 observations for sedated patients, and 130 observations for patients admitted for other symptom control. The weighted kappa values were practically equal to or greater than 0.90 between nurses and nurses and physicians. The agreement level between observers for each RASS score was roughly 90%. The correlation between the RASS and the Ramsay and Glasgow Scale values was analyzed for 196 observations recorded in 80 patients. The sedation scale of the RASS had a strong correlation with both the Ramsay (Spearman's ρ, -0.89; P < 0.001) and the Glasgow Coma Scales (Spearman's ρ, 0.85; P < 0.001).

CONCLUSION

These data support the use of the RASS in Spanish patients with advanced cancer.

Cut points on 0-10 numeric rating scales for symptoms included in the Edmonton Symptom Assessment Scale in cancer patients: a systematic review

CONTEXT

To improve the management of cancer-related symptoms, systematic screening is necessary, often performed by using 0-10 numeric rating scales. Cut points are used to determine if scores represent clinically relevant burden.

OBJECTIVES

The aim of this systematic review was to explore the evidence on cut points for the symptoms of the Edmonton Symptom Assessment Scale.

METHODS

Relevant literature was searched in PubMed, CINAHL®, Embase, and PsycINFO®. We defined a cut point as the lower bound of the scores representing moderate or severe burden.

RESULTS

Eighteen articles were eligible for this review. Cut points were determined using the interference with daily life, another symptom-related method, or a verbal scale. For pain, cut point 5 and, to a lesser extent, cut point 7 were found as the optimal cut points for moderate pain and severe pain, respectively. For moderate tiredness, the best cut point seemed to be cut point 4. For severe tiredness, both cut points 7 and 8 were suggested frequently. A lack of evidence exists for nausea, depression, anxiety, drowsiness, appetite, well-being, and shortness of breath. Few studies suggested a cut point below 4.

CONCLUSION

For many symptoms, there is no clear evidence as to what the optimal cut points are. In daily clinical practice, a symptom score ≥4 is recommended as a trigger for a more comprehensive symptom assessment. Until there is more evidence on the optimal cut points, we should hold back using a certain cut point in quality indicators and be cautious about strongly recommending a certain cut point in guidelines.

Association between histological features in temporal artery biopsies and clinical features of patients with giant cell arteritis

BACKGROUND

In most cases of giant cell arteritis (GCA) the diagnosis is confirmed by temporal artery biopsy. Aside from the diagnostic purpose, histological parameters may serve as prognostic markers.

OBJECTIVES

To review positive temporal artery biopsies ofGCA in an attempt to correlate various histological parameters with clinical features, disease complications and outcome.

METHODS

Positive biopsies from 65 GCA patients were randomly selected for review by a single pathologist. In each biopsy the following parameters were scored: intensity and location of the inflammatory infiltrate, presence of giant cells and other cell types, fragmentation and calcification of the internal elastic lamina, intimal thickening, and presence of luminal thrombus. Clinical data were obtained from the patients' charts. Intensity of the initial systemic inflammatory reaction (ISIR) at the time of diagnosis was scored by the presence of five parameters: fever, anemia, thrombocytosis, leukocytosis, and sedimentation rate >100 mm/hr.

RESULTS

In cases with bilateral positive biopsy (n=27), there was good correlation between the two sides regarding intensity of inflammation (r= 0.65, P< 0.001), location of the infiltrate (r= 0.7, P< 0.001), degree of intimal thickening (r= 0.54, P 0.001), and presence of giant cells (r= 0.83, P< 0.001). The rate of corticosteroid discontinuation tended to be quicker in patients with inflammatory infiltrates confined mainly to the adventitia, but other histological parameters did not affect this rate.

CONCLUSIONS

Inflammatory infiltrates confined to the adventitia were associated with more neuro-ophthalmic ischemic manifestations, weak/moderate ISIR at the time of diagnosis, and faster rate of corticosteroid discontinuation. No association was found between other temporal artery biopsy histological parameters and clinical features of GCA patients.

Neuropsychiatric symptom assessments in toxic exposure

The goal of this review is to provide guidelines for evaluating psychiatric and mood changes that result from neurotoxicity. Mood changes that are often seen to varying degrees in neurotoxicity include increased anxiety, depression, irritability, impulsiveness, and psychosis. Some common agents that induce neurotoxicity include drugs, heavy metals, and organophosphates with presentations varying somewhat depending upon the mechanism of toxicity. The authors discuss in detail psychiatric assessment for patients with suspected of having neurotoxicologic syndrome.

Diagnosis of colon cancer differs in younger versus older patients despite similar complaints

BACKGROUND

Colon cancer is common, affecting mostly older people. Since age is a risk factor, young patients might not be given the same attention as older ones regarding symptoms that could imply the presence of colon cancer.

OBJECTIVES

To investigate whether young patients, i.e., under age 50, complain of symptoms for longer than older patients until the diagnosis of colon cancer is established.

METHODS

In this retrospective cohort study, patients were divided into two groups: < 50 years old (group 1) and > or = 50 (group 2). All had undergone surgery for left or right-colon cancer during the 10 year period of the study from January 2000 through December 2009 at one medical center. Rectal and sigmoid cancers were excluded. Data collected included age, geander, quantity and quality of complaints, duration of complaints, in-hospital versus community diagnosis, pathological staging, the side of colon involved, and overall mortality. The primary outcome was the quality and duration of complaints. Secondary outcomes were the pathological stage at presentation and the mortality rate.

RESULTS

The study group comprised 236 patients: 31 (13.1%) were < 50 years old and 205 (86.9%) were > or = 50. No significant difference was found in the quantity and quality of complaints between the two groups. Patients in group 1 (< 50 years) complained for a longer period, 5.3 vs.2.4 months (P= 0.002). More younger patients were diagnosed with stage IV disease (38.7% vs. 21.5%, P= 0.035) and fewer had stage I disease (3.2% vs. 15.6%, P= 0.06); the mortality rates were similar (41.9% vs. 39%). Applying a stepwise logistic regression model, the duration of complaints was found to be a predictor of mortality (P= 0.03, OR 1.6, 95% CI 1-3.6), independently of age (P= 0.003) and stage (P< 0.001).

CONCLUSIONS

Younger patients are more often diagnosed with colon cancer later, at a more advanced stage. Alertness to patients' complaints, together with evaluation regardless of age but according to symptoms and clinical presentation are crucial. Large-scale population-based studies are needed to confirm this trend.

Laparoscopic radical prostatectomy in a cadaveric renal transplant patient: first case in Thailand and the authors first experience--a case report

OBJECTIVE

To report the authors' experience in laparoscopic radical prostatectomy for the treatment of localized prostate carcinoma in a cadaveric renal transplant recipient.

MATERIAL AND METHOD

A 64-year-old man with chronic renal failure unknown cause had a transplant cadaveric donor kidney about nine years ago. Creatinine clearance was estimated about 68.61 ml/min. He was presented with lower urinary tract symptoms in 2008. He was diagnosed and was treated as benign prostatic hyperplasia. Digital rectal examination was normal and prostate specific antigen (PSA) was 10.84 ng/ml when he was followed-up in 2010. The authors did a prostate gland biopsy, one of four cores from right lobe of prostate gland revealed prostatic adenoma with Gleason score of 6 (3 + 3). Bone scan did not show any sign of metastases. The authors performed a Laparoscopic radical prostatectomy, extraperitoneal technique.

RESULTS

The patient underwent successful laparoscopic radical prostatectomy without any complications. The operative time was 210 minutes, the estimated blood loss of 300 ml. Pathological analyses revealed negative surgical margins with focal extraprostatic extension, and no seminal vesical, lymphatic, and perineural invasion. The patient tolerated the procedure well and was discharged on day 4. At fourth months, the patient was continent, PSA was 0.003, and renal function stable. At one year, PSA was 0.011 ng/ml and the creatinine was 1.15 mg/dl.

CONCLUSION

The authors experience suggests that extraperitoneal laparoscopic radical prostatectomy is a technically feasible and safe treatment of localized prostate cancer in renal transplant recipients.
