Killian-Jamieson (K-J) diverticulum is a rare cervical oesophageal diverticulum, less commonly encountered compared with Zenker's diverticulum (ZD). We report a case of K-J diverticulum in a 52-year-old lady who presented with sensation of lump in the neck and food stuck in the throat of 5 years duration. Esophagogram showed a large rightsided pharyngoesophageal diverticulum which was confirmed on endoscopy. The patient underwent a diverticulopexy and recovered without complications. Her symptoms had improved. In this report, we review the literature and describe our surgical technique.
OBJECTIVE: To evaluate power doppler ultrasonography (PDU)-directed prostate biopsy in patients with elevated serum prostate specific antigen (PSA) levels.
MATERIALS AND METHODS: Men with serum total PSA levels of more than 4 ng/ml undergoing biopsy for the first time were included. Grey-scale transrectal ultrasound (TRUS) and PDU were performed. PDU signal on vascularity accumulation and perfusion characteristics were recorded and graded as normal or abnormal in the peripheral zone of the prostate. Abnormalities were defined on transverse image as radial or arc hypervascularities. A biopsy regime based on Vienna-normogram was performed in all patients.
RESULTS: Overall, prostate adenocarcinoma detection rate was 21.4% and abnormal accumulation on PDU signal was identified in 96.7% of those patients (p = 0.01). PDU directed prostate biopsies were positive in 66.7% of the patients with prostate cancer. The sensitivity, specificity, positive predictive value and negative predictive value of PDU signal alone for prostate cancer detection was 96.7%, 24.5% and 96.4% respectively, and PDU guided biopsies were 66.7%, 24.5%, 19.4% and 73% respectively.
CONCLUSIONS: The high sensitivity and negative predictive value of PDU makes it useful as an aid for TRUS biopsy in selected patient with previous negative biopsies at risk of harbouring prostate cancer.
OBJECTIVES: To evaluate the initial, long-term, and durable response rates to terazosin, placebo, or other therapies in patients with chronic prostatitis/chronic pelvic pain syndrome.
METHODS: A total of 100 subjects, aged 20 to 50 years, who met the National Institutes of Health criteria for chronic prostatitis/chronic pelvic pain syndrome and had not previously been treated with alpha-blockers, were entered in a 14-week, double-blind comparison of terazosin or placebo therapy. Nonresponders and responders with subsequent relapse were treated with terazosin or other medications (open label). The criterion for response was a score of 0 to 2 on the National Institutes of Health Chronic Prostatitis Symptom Index quality-of-life item. The initial response was evaluated at week 14, and the long-term response was evaluated after a median of 38 weeks (range 34 to 42), regardless of any additional treatment. A durable response was defined as an initial response without additional treatment.
RESULTS: Of the 43 patients in the terazosin group, 24 (56%) had an initial response compared with 14 (33%) of 43 subjects in the placebo group (P = 0.03). Long-term responses were noted in 23 (56%) of 41 assessable subjects treated with terazosin initially compared with 12 (32%) of 38 assessable subjects treated with placebo (P = 0.03). Of the nonresponders and initial responders with relapse, 7 (41%) of 17 subjects responded to terazosin compared with 7 (21%) of 34 given other treatment (P = 0.12). Durable responses occurred in 18 (44%) of the 41 assessable patients treated initially with terazosin and in 6 (16%) of 38 treated initially with placebo (P = 0.01).
CONCLUSIONS: Patients treated with terazosin were more likely to have initial, long-term, and durable responses than those treated with placebo.
OBJECTIVES: To determine the prevalence of chronic prostatitis/chronic pelvic pain syndrome (National Institutes of Health Category III prostatitis) in Penang, Malaysia and estimate the proportion of cases ascertained by population survey that met consensus clinical criteria for "chronic prostatitis."
METHODS: One percent of 20 to 50-year-old men in Penang, Malaysia were surveyed using the National Institutes of Health Chronic Prostatitis Symptom Index. A clinical evaluation that included lower urinary tract localization studies was recommended for symptomatic subjects who met the survey definition to identify bacterial prostatitis and other diagnoses that would exclude them from the consensus clinical definition for chronic prostatitis (Category III).
RESULTS: Of 3147 subjects surveyed, 275 (8.7%) met the survey criteria for chronic prostatitis. The prevalence of chronic prostatitis was 8.0% among Malays, 8.9% among non-Malays, and 16% among noncitizens (P = 0.025). The prevalence increased with age: 6.3% in 20 to 30-year-old men, 8.9% in 31 to 40-year-old men, and 12.6% in 41 to 50-year-old men (P <0.001). Of 87 subjects evaluated clinically, 65 (75%) met the consensus clinical criteria for chronic prostatitis.
CONCLUSIONS: Chronic prostatitis represents an important, international healthcare problem. A thorough clinical evaluation is necessary to verify that chronic prostatitis is indeed responsible for a patient's pelvic pain and lower urinary tract symptoms.
PURPOSE: We evaluate terazosin therapy for chronic prostatitis/chronic pelvic pain syndrome.
MATERIALS AND METHODS: The study included 100, 20 to-50-year-old subjects who met the consensus criteria for chronic prostatitis/chronic pelvic pain syndrome and had not received previous alpha-blockers. Subjects were randomized to receive terazosin with dose escalation from 1 to 5 mg. daily or placebo for 14 weeks. The primary criterion for response was scoring 2 or less ("delighted-to-mostly satisfied") on the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) quality of life item. The secondary criterion for response was greater than 50% reduction in NIH-CPSI pain score at 14 weeks. Other outcomes included total and NIH-CPSI domain scores, International Prostate Symptom Score, peak urinary flow rate, post-void residual urine and adverse effects.
RESULTS: Using the primary criterion 24 of 43 evaluable subjects (56%) responded in the terazosin group compared to 14 of 43 (36%) in the placebo group (p = 0.03). Using the secondary criterion 26 of 43 subjects (60%) responded in the terazosin group compared to 16 of 43 (37%) in the placebo group (p = 0.03). The terazosin group had greater reductions (p <0.05) in NIH-CPSI total score, individual domain scores and International Prostate Symptom Score than the placebo group. There was no difference in peak urinary flow rate or post-void residual. In the terazosin group 18 patients (42%) had side effects compared to 9 (21%) in the placebo group (p = 0.04).
CONCLUSIONS: Terazosin proved superior to placebo for patients with chronic prostatitis/chronic pelvic pain syndrome who had not received alpha-blockers previously.
The objective of the study is to determine the short- and long-term utility of the Chinese, Malay and English versions of the National Institutes of Health--Chronic Prostatitis Symptom Index (NIH-CPSI) in our ethnically diverse population. The NIH-CPSI was translated into Chinese and Malay, and then verified by back translation into English. Subjects included 100 new chronic prostatitis/chronic pelvic pain (CP/CPPS) patients, 71 new benign prostatic hyperplasia patients and 97 healthy individuals. Reliability was evaluated with test-retest reproducibility (TR) by calculating intraclass correlation coefficients (ICC). Internal consistency was evaluated by calculating Cronbach's alpha (alpha). Validity assessments included discriminant and construct validity. (Presented in the order of Chinese, Malay then English). ICC values for short-term (1 week) TR were 0.90, 0.80 and 0.89, while ICC values for long-term (14 weeks) TR were 0.54, 0.61 and 0.61. Cronbach's alpha values were 0.63, 0.62 and 0.57. The NIH-CPSI total score discriminated CP/CPPS patients (P<0.001) from the control groups with receiver operating curve values of 0.95, 0.98 and 0.94, respectively. Construct validity, reflected by the correlation coefficient values between the International Prostate Symptom Score and the NIH-CPSI of CP/CPPS patients were 0.72, 0.49 and 0.63 (all P<0.05). The Chinese, Malay and English versions of the NIH-CPSI each proved effective in our population. Short-term TR and discriminant validity were excellent for all three versions. However, long-term TR was only moderate, which might reflect variation in patients' perceptions of symptoms over time.
