Infrequent use of antidepressants in depressed individuals (an interview and prescription database study in a defined Swedish population 2001-2002).

PURPOSE: To investigate whether antidepressants are over-used, under-used, or misused, by determining to what extent the depressed individuals in a defined population are treated with antidepressant medication and, from the other end, to what extent prescribed antidepressants are aimed for the treatment of depression. SUBJECTS AND METHOD: From an individual based prescription database in the County of Jämtland, 2048 individuals representative for the general population were selected. The presence of current depression in these individuals was screened by a mailed self-screening questionnaire. Individuals with depression according to the questionnaire were interviewed by a psychiatrist using a structured interview (SCAN) to confirm the diagnosis. Their use of antidepressants was obtained from the prescription database. RESULTS: Sixty-two (4.5%) out of 1375 were diagnosed with depression and 17 (27%) of these were taking an antidepressant. In addition 44 individuals, currently not depressed, were taking antidepressants. Twenty-five of these were interviewed per telephone and it was found that the indications for 18 of them were continuation treatment of depression, and for seven of them pain, sleep disturbance or anxiety. CONCLUSION: Antidepressants appear to be under-used in the population. Only one in four of the depressed individuals was treated with antidepressant medication. Those who had antidepressant medication without being currently depressed had, with few exceptions, either continuation treatment for depression in remission or treatment on other approved indications.

Increased antidepressant use and fewer suicides in Jämtland county, Sweden, after a primary care educational programme on the treatment of depression.

OBJECTIVE: To consider and evaluate a continuing medical education programme for general practitioners (GPs) on depression in Jämtland county, Sweden, inspired by the Gotland study. METHOD: Interactive seminars were conducted between 1995 and 2002 in Jämtland county. For evaluation, suicide rates and annual sales statistics of antidepressants were compared with national averages. Questionnaires were used for information about attitudes and prescribing habits. RESULTS: The suicide rate in Jämtland decreased to the same level as the national average. The use of antidepressants increased from 25% below the Swedish average to the same level. The selective serotonin re-uptake inhibitors (SSRIs) were preferred because of their tolerability. Suicide issues were considered to be most important in the management of depressed patients. CONCLUSION: A trend towards a greater prescription of antidepressants and fewer suicides after an educational programme on depression for GPs replicated the findings from the Gotland study. The educational programme will be conducted annually and could be a model for other regions.

Selective serotonin reuptake inhibitor antidepressants and the risk of suicide: a controlled forensic database study of 14,857 suicides.

OBJECTIVE: To test the hypothesis that selective serotonin reuptake inhibitor (SSRI) antidepressants may have a suicide emergent effect, particularly in children and adolescents. METHOD: Detections of different antidepressants in the forensic toxicological screening of 14 857 suicides were compared with those in 26,422 cases of deaths by accident or natural causes in Sweden 1992-2000. RESULTS: There were 3411 detections of antidepressants in the suicides and 1538 in the controls. SSRIs had lower odds ratios than the other antidepressants. In the 52 suicides under 15 years, no SSRIs were detected. In 15-19-year age group, SSRIs had lower relative risk in suicides compared with non-SSRIs. CONCLUSION: The hypothesis that treatment of depressed individuals with SSRIs leads to an increased risk of suicide was not supported by this analysis of the total suicidal outcome of the nationwide use of SSRIs in Sweden over a period of 9 years, either in adults or in children or adolescents.

Nocturia and depression.

OBJECTIVE: To assess the possible relationship between major depression (MD) and nocturia. SUBJECTS AND METHODS: An unselected group of adult men and women, living in the city of Ostersund, Sweden, were sent a postal questionnaire containing questions on somatic and mental health, sleep, sleepiness and nocturia. For depression diagnostics the Major Depression Inventory (MDI) was used. RESULTS: The mean (sd) ages of the men and women were 48.0 (18.2) and 50.1 (19.1) years, respectively. Two or more nocturnal micturition episodes occurred in 15.6% of the men and 16.5% of the women. In a multiple logistic regression analysis independent correlates (with 95% confidence intervals) for >/= 2 nocturnal voids in men were: MD 6.5 (2.6-15.6); health, fair vs good, 1.8 (1.0-3.9); health, poor vs good, 2.7 (1.1-4.8); age, 60-74 vs 18-29, 3.6 (1.5-8.4) and age >/= 75 vs 18-29 6.7 (2.6-17.4); and in women: MD 2.8 (1.3-6.3); health, fair vs good, 1.9 (1.1-3.2); health, poor vs good, 4.3 (2.6-8.2); age, 60-74 vs 18-29, 3.8 (1.8-7.8), and age >/= 75 vs 18-29, 8.6 (4.0-18.6). Age < 60 years was deleted by the logistic model in both sexes. CONCLUSION: MD is associated with a six-fold increase in nocturia in men and a three-fold increase in women, after accounting for age and health. Possible pathogenetic mechanisms of this relationship may involve both increased nocturnal diuresis via a disturbed 24-h rhythm of antidiuretic hormone secretion, and a decrease in nocturnal bladder capacity through a central and/or peripheral serotonergic effect.

Indications for and outcome of antidepressant medication in a general population: a prescription database and medical record study, in Jämtland county, Sweden, 1995.

OBJECTIVE: To examine the indications for prescribing antidepressants and the clinical outcome when they are prescribed for the treatment of depression, and compare tricyclic antidepressants (TCAs) and selective serotonin re-uptake inhibitors (SSRIs) in these respects. METHOD: A naturalistic study of a prospective prescription monitoring database and medical records. RESULTS: Depression was the indication for 23% of the tricyclic treatments and for 82% of the SSRI treatments. A successful treatment of the depression was found in 20% of the TCA cases and 41% of the SSRI cases (NS). CONCLUSION: This study provides evidence that the main use of SSRIs in 1995 is the treatment of depression. The study implies that SSRIs have a more favourable outcome in "real life" than TCAs.

Treatment of snoring and obstructive sleep apnea with a mandibular protruding device: an open-label study.

The study objectives were to describe the changes in signs and symptoms of obstructive sleep apnea (OSA) and snoring using a mandibular protruding device (MPD) and to define the group of responders. The design of the study was a nonrandomized, open-labeled, prospective clinical study with a duration of 6 months. The setting was a hospital sleep laboratory and an ear, nose, and throat and dental outpatient clinic. Patients included 35 individuals treated: 22 with a diagnosis of OSA and 13 who snored without apnea. The intervention before MPD prescription entailed a medical examination, a one-night somnographic registration, a questionnaire, and a clinical jaw function examination. All procedures were iterated at the 6-month follow-up. When the patients used the MPD, the subjective symptoms decreased significantly (p < 0.001). Twenty-four of the 35 patients were classified as responders, i.e., reduced their symptoms > or = 50%. In the groups of OSA patients, the mean peak intensity of the snoring sound decreased from 71.6 dB to 62.0 dB (p < 0.001) and in the group of snorers, from 63.5 dB to 57.5 dB (p < 0.05). Eighteen of the 22 OSA patients decreased their ODI values by > or = 50% (responders). The mean ODI decreased from 15.4 to 3.5 (p < 0.001) and the blood oxygen saturation, SaO(2) nadir, increased from mean 81.9 to 85.7 (n.s.). Most patients with tongue base hyperplasia were classified as responders to the MPD treatment. In conclusion, a 6-month perspective shows that the MPD could be an effective treatment in reducing signs and symptoms of OSA and/or snoring, the compliance was acceptable and only minor adverse events occurred.

Patterns of psychoactive substance detection from routine toxicology of suicides in Mobile, Alabama, between 1990 and 1998.

BACKGROUND: Postmortem toxicology can be useful for reconstructing some clinically important events occurring before a suicide. Its utility may be improved by examining patterns of detected substances in a population over time. METHODS: Toxicology was performed for 333 (96%) of the 346 suicides occurring in Mobile County, Alabama, between October 1990 and September 1998. Detected psychoactive substances were grouped in three categories: alcohol, cocaine, and cannabis; abusable prescription medications; and non-abused psychotropic medications. The overlap between these three categories was assessed. RESULTS: Psychoactive substances were detected in 227 (68%) of 333 suicides. Of the cases positive for any prescription psychoactive medication, 2/3 were positive for an abusable medication. An abusable substance was found in 56% of cases positive for non-abused psychotropic medication. Alcohol, cocaine and/or cannabis were found in 34% of cases with abusable prescription medications and in 33% with non-abused psychotropics. LIMITATIONS: Clinicians must be aware of a number of methodological realities when interpreting routine postmortem toxicology results. CONCLUSIONS: Routine surveillance of psychoactive substances among suicides can provide useful data for directing and monitoring strategies for suicide prevention in clinical practice.

Suicides are seldom prescribed antidepressants: findings from a prospective prescription database in Jämtland county, Sweden, 1985-95.

OBJECTIVE: This study presents data relating to prospectively monitored treatment and post-mortem toxicology of individuals who committed suicide. METHOD: A case-control study of prospectively monitored pharmacological treatment in suicides and controls. Psychiatric records and post-mortem toxicology were also studied. RESULTS: Fifty-nine subjects who committed suicide purchased twice the number of prescriptions as the 118 controls. Sixteen cases received psychiatric in-patient care compared to four of the controls. In the last 3 months prior to suicide, 38 cases (64%) were dispensed drugs: anxiolytics-hypnotics in 17 cases (29%), antipsychotics in six cases (10%) and antidepressants in seven cases (12%). More psychiatrists than GPs prescribed antidepressants. About one-third of psychotropic drugs were retrieved in post-mortem toxicology. CONCLUSION: There is a frequent use of psychotropics and psychiatric care among suicides; however, few used antidepressants and complied. Many suicides are still misdiagnosed and are not adequately treated.

The anesthetic onset and duration of a new lidocaine/prilocaine gel intra-pocket anesthetic (Oraqix) for periodontal scaling/root planing.

BACKGROUND: A new non-injection anesthetic, lidocaine/prilocaine gel (Oraqix, AstraZeneca) in a reversible thermosetting system, has been developed to provide local anesthesia for scaling/root planing (SRP). The aim of this study was to determine the anesthetic onset and duration of the gel for SRP in patients with periodontitis. METHODS: 30 patients were randomized to either 30 s, 2 min, or 5 min of treatment with the gel prior to SRP of a tooth. The gel was applied to periodontal pockets with a blunt applicator. On completion of the SRP of each tooth (2-3 teeth treated/patient), the patients rated their pain on a 100-mm visual analogue scale (VAS). RESULTS: The median VAS pain score was 7.5 mm in the 30-s group, 28.5 mm in the 2-min group, and 15.5 mm in the 5-min group, with a significant difference between the 30-s and 2-min groups (p=0.03). In 2 patients in the 5-min group, but none in the other groups, the SRP was interrupted due to pain. The mean duration of anesthesia measured as pain on probing were 18.1, 17.3, and 19.9 min in the 30-s, 2-min, and 5-min groups, respectively. There were no reports of numbness of the tongue, lip, or cheek, neither were there any adverse local reactions in the oral mucosa. The gel was easy to apply and did not interfere with the SRP procedure. CONCLUSION: Oraqix provides anesthesia after an application time of 30 s, with a mean duration of action of about 17 to 20 min.

Psychoactive substances in suicides. Comparison of toxicologic findings in two samples.

The goal in this study was to assess if there is any constancy in detections of psychoactive substances in consecutive suicides. Toxicologic findings in 179 suicides in San Diego County, California, between 1981 and 1982, and 333 suicides in Mobile County, Alabama, between 1990 and 1998, were compared. Alcohol was detected in about 30% of suicides in both samples. Abusable prescription psychoactive substances, i.e., benzodiazepines and opiates, were detected in one fifth of cases in both locations. Nonabusable prescription psychoactive substances, mainly antidepressants, were found in more suicides in Mobile than in San Diego. Detection rates of different classes of psychoactive substances have not changed much in the past decade. Detection of alcohol, cocaine, or cannabis in about 40% of suicides supports the clinical practice of discouraging consumption of these substances in depressed patients. Another challenge is the low rate of detection of antidepressants in suicide, which suggests undertreatment of depression in suicides. Continued reporting of routine, comprehensive, toxicologic findings in suicides is useful to monitor patterns of use of psychoactive substances in this group and to guide suicide prevention in clinical practice and public health policy.
