Adjustment disorder in cancer patients after treatment: prevalence and acceptance of psychological treatment.

PURPOSE: To investigate the prevalence of adjustment disorder (AD) among cancer patients and the acceptance of psychological treatment, in relation to sociodemographic, clinical, and psychological factors. METHODS: Breast, prostate, and head and neck cancer patients of all stages and treatment modalities (N = 200) participated in this observational study. Patients completed the Hospital Anxiety and Depression Scale, Checklist Individual Strength, Distress Thermometer and problem list. Patients with increased risk on AD based on these questionnaires were scheduled for a diagnostic interview. Patients diagnosed with AD were invited to participate in a randomized controlled trial on the cost-effectiveness of psychological treatment. Participation in this trial was used as a proxy of acceptance of psychological treatment. Logistic regression analyses were used to investigate associated factors. RESULTS: The overall prevalence of AD was estimated at 13.1%. Sensitivity analyses showed prevalence rates of AD of 11.5%, 15.0%, and 23.5%. Acceptance of psychological treatment was estimated at 65%. AD was associated both with being employed (OR = 3.3, CI = 1.3-8.4) and having a shorter time since diagnosis (OR = 0.3, CI = 0.1-0.8). CONCLUSION: Taking sensitivity analysis into account, the prevalence of AD among cancer patients is estimated at 13 to 15%, and is related to being employed and having a shorter time since diagnosis. The majority of cancer patients with AD accept psychological treatment.

Treatment of Helicobacter pylori infection with low or high dose omeprazole combined with amoxycillin and the effect of early retreatment.

BACKGROUND: Cure rates of H. pylori infection, using dual therapy with omeprazole and amoxycillin, vary considerably and the efficacy of retreatment with this regimen in the case of initial failure is controversial. Therefore, we conducted a large prospective double-blind randomized trial, studying the efficacy of low vs. high dose omeprazole in dual therapy and of early retreatment with the same regimens. METHODS: One hundred and sixty-eight consecutive H. pylori-positive patients, suffering from either peptic ulcer disease or functional dyspepsia, were enrolled. Group I (n = 84) received omeprazole 20 mg b.d. plus amoxycillin 750 mg t.d.s., for 2 weeks. Group II (n = 84) received omeprazole 40 mg t.d.s. plus amoxicillin 750 mg t.d.s., for 2 weeks. RESULTS: The H. pylori eradication rate was 60.2% in group I and 64.3% in group II (P = 0.59). Cure of H. pylori infection was significantly better in patients with peptic ulcer disease, compared to non-ulcer dyspeptics (P = 0.016). Retreatment, given in 54 patients, was successful in 21.4% patients in group I and in 28% patients in group II (P = 0.58). CONCLUSIONS: High dose of omeprazole has no advantage compared to low dose in terms of eradication efficacy. Early retreatment with the same regimen offers limited improvement in cure rate. Presence of peptic ulcer disease influences cure rates significantly.

Effect of specimen collection techniques, transport media, and incubation of cultures on the detection rate of Helicobacter pylori.

Culture and histologic examination are considered "gold standard" methods for the detection of Helicobacter pylori, but discrepancies may occur with either method. Failure to detect Helicobacter pylori may be due to sampling error, inappropriate transport or culture media, or insufficient duration of the incubation period. Rates of detection of Helicobacter pylori by culture and histopathologic examination of gastric mucosal biopsy specimens were determined in 102 consecutive dyspeptic patients. In a separate group of 60 patients, rates of detection of Helicobacter pylori by culture of antral brushings and the length of incubation required in selective and nonselective culture media were studied. In the first group of 102 patients, the combination of culture and histologic examination detected 54 Helicobacter pylori-positive patients, whereas the separate techniques each detected 51 Helicobacter pylori-positive patients. In the second group of 60 patients evaluated by culture of antral brushings, the rate of detection of Helicobacter pylori was 25 of 60 and was similar for culture (25/60) and histologic examination (25/60). In the second group the length of incubation required to detect Helicobacter pylori was different for selective and nonselective media. In nonselective media, incubation of up to ten days was required to detect all Helicobacter pylori infections, whereas in selective media seven days was sufficient. Rates of detection of Helicobacter pylori by culture, histopathologic examination and culture from brushings were similar, whereas the combination of culture and histopathologic examination achieved a superior rate of detection. The incubation period required for the detection of Helicobacter pylori by culture was a minimum of seven days and was dependent on the culture medium used.
