Neurological complications of prolonged hunger strike

We investigated neurological findings in 41 prisoners (mean age: 28.6) who participated in a hunger strike between 2000 and 2002. All cases were evaluated using neuropsychological, neuroradiological, and electrophysiological methods. The total duration of fasting ranged from 130 to 324 days (mean 199 days). All cases had 200-600 mg/day thiamine orally for 60-294 days (mean 156) during the hunger strike, and had neurological findings consistent with Wernicke-Korsakoff syndrome. All 41 patients exhibited altered consciousness which lasted from 3 to 31 days. All patients also presented gaze-evoked horizontal nystagmus and truncal ataxia. Paralysis of lateral rectus muscles was found in 14. Amnesia was apparent in all cases. Abnormal nerve conduction study parameters were not found in the patient group, but the amplitude of compound muscle action potential of the median and fibular nerves and sensory nerve action potential amplitude of the sural nerve were lower than the control group, and distal motor latency of the posterior tibial nerve was significantly prolonged as compared with the control group. The latency of visual evoked potential was prolonged in 22 cases. Somatosensory evoked potential (P37) was prolonged but not statistically significant. Our most significant finding was that the effect of hunger was more prominent on the central nervous system than on the neuromuscular system, despite the fact that all patients were taking thiamine. In our opinion, partial recovery of neurological, and neurocognitive signs in prolonged hunger could be a result of permanent neurological injury.

Intrabiliary rupture in liver hydatid cysts: results of 20 years' experience

To assess the diagnostic tools and results of treatment of biliary rupture observed in liver cyst hydatids, clinical findings of 562 patients with hepatic hydatid disease were reviewed. Imaging techniques were not very effective to determine intrabiliary ruptures. Rates of rupture sizes determined in the patients were as follows; 22 (%24.7) large, 38 (%42.7) small, and 29 (%32.6) occult. Most frequently utilized procedures for patients with intrabiliary rupture were Roux-en-y cystojejunostomy, tube drainage + omentoplasty, sutured fistula + omentoplasty, and sutured fistula + tube drainage. Of the total 25 external biliary fistulas, 21 closed spontaneously. Of the four fistulas that did not close, one was managed by internal drainage and three by endoscopic sphincterotomy. Preoperative diagnosis of biliary rupture in liver hydatid cyst allows early planning of operation and helps the surgeon design the operative strategy. In the treatment of cases with large rupture, internal drainage may be proposed.

A brief behavioural treatment of chronic post-traumatic stress disorder in earthquake survivors: results from an open clinical trial

BACKGROUND

Natural disasters such as earthquakes affect large numbers of people. Given the extent of the mental health problem following earthquakes, brief, effective and cost-effective treatment interventions are urgently needed. The present study examined whether cognitive-behavioural treatment could be shortened to a minimum number of sessions without undermining its effectiveness in post-traumatic stress disorder (PTSD).

METHOD

The study participants (N=231) were consecutive referrals to five project sites in the earthquake region in Turkey a mean of 13 months after the disaster. A modified behavioural treatment (BT) was used, which involved self-exposure instructions based on an enhancement of 'sense of control' rather than a habituation rationale and minimal cognitive interventions. The duration of treatment was variable, involving as many sessions as required for clinical improvement. Survival analysis was used to explore the minimum number of sessions required for clinical improvement, and multiple regression analysis to examine the predictors of outcome.

RESULTS

The survivors received a mean of 4-3 sessions. Significant treatment effects and clinically meaningful effect sizes were noted on all measures. The treatment improved all PTSD and depression symptoms. The cumulative proportion of improved cases was 76% after one session and 88% after two sessions. No baseline variable predicted treatment outcome.

CONCLUSIONS

The modified BT appears to be promising as an effective one- or two-session intervention for earthquake survivors. It may be particularly useful in large-scale disasters as a cost-effective treatment that can be relatively easily disseminated to mass populations. Further research is needed to clarify the possible role of a treatment focus on sense of control in rapid recovery from traumatic stress.

Olanzapine efficacy in the treatment of essential tremor

We investigated the anti-tremor effect of olanzapine, a novel atypical antidopaminergic drug, in 37 patients with essential tremor (ET) in an open-label and prospective study by clinical scoring and patient self-evaluation. Olanzapine monotherapy appears to be efficacious for the treatment of ET. Further clinical trials with control groups are indicated to establish the efficacy of olanzapine in patients with ET.

Importance of psychiatric intervention in intolerances in endoscopic procedures

Despite the fact that pre-medication, in a number of different drug combinations, has been used for a long time in endoscopy units, and has been subject to extended clinical studies, it is still not possible to claim that it has attained an ideal state with regard to patient tolerance to endoscopy procedures. In this clinical study, we have investigated the effects of psychological intervention in addition to medication, which we used on patients with intolerance to endoscopy. Intolerance was very high in all endoscopic procedures (15.8% total). It was observed that average midazolam doses were significantly higher in intolerant than in tolerant patients. It was found that in patients who had received psychiatric intervention, the decrease in midazolam dose was statistically significant in a subsequent endoscopy procedure.

A study of the validity of a screening instrument for traumatic stress in earthquake survivors in Turkey

The validity of a Traumatic Stress Symptom Checklist (TSSC), which was developed as part of a Screening Instrument for Traumatic Stress in Earthquake Survivors (SITSES), was examined in 130 survivors of the recent earthquake in Turkey. Data were obtained on the TSSC, which consists of 17 DSM-IV posttraumatic stress disorder (PTSD) items and 6 symptoms of depression. The Clinician-Administered PTSD Scale and the Major Depressive Episode module of the Semistructured Clinical Interview for DSM-IV were used for comparison with the TSSC. The results indicated that the TSSC has high internal consistency and satisfactory sensitivity and specificity in predicting the diagnosis of PTSD and major depression. The SITSES appeared to be a useful instrument in screening earthquake survivors for PTSD, major depression, illness severity, and risk factors associated with traumatic stress responses.

[Thromboembolic prophylaxis after major abdominal surgery]

PURPOSE

To investigate the efficacy of prophylaxis modalities after major abdominal surgery.

PATIENTS AND METHODS

Patients who underwent major abdominal surgery between October 1998 and October 1999 were randomly divided into 3 groups. The patients in Group 1 received compression stockings, in Group 2 0.3 ml low-molecular weight heparin (nadroparine calcium 0.3 ml, 2850 IU AXa LMWH) subcutaneously and in Group 3 compression stockings and 0.3 ml LMWH. All symptomless patients evaluated with low extremity deep venous Doppler ultrasonography (DUSG), and patients who had pulmonary embolus (PE) suspicion evaluated with pulmonary scintigraphy.

RESULTS

There were 91 patients in Group 1, 91 patients in Group 2 and 92 patients in Group 3. The mean age was 57.25 +/- 13.12, 54.53 +/- 13.54, and 53.65 +/- 13.28 respectively. Male/female ratio was 51/38, 56/35 and 62/30, in Group 1, 2 and 3 respectively. Twenty-seven patients in Group 1, 26 patients in Group 2 and 37 patients in Group 3 had risk factors. DUSG showed deep venous thrombosis (DVT) on the 7th postoperative day in 10 patients in Group 1, in 8 patients in Group 2 and in 3 patients in Group 3. Pulmonary scintigraphy showed PE suspicion in 6 patients in Group 1, 1 patient in Group 2 and 1 patients in Group 3. Wound hematoma and hemorrhage from abdominal drains were developed in 1/0, 8/2 and 3/1 patients in Groups 1, 2 and 3 respectively. Four patients in Group 1 and 2 patients in Group 2 died during the treatment (2.2%). Satistical analysis showed significant differences in PE and wound hematoma between Groups 1 and 2, in DVT and PE between Groups 1 and 3, in risk factors between Groups 2 and 3 (p < 0.05). The differences in DVT and PE and hematoma between group 2 and 3 were not significant.

CONCLUSION

All treatment modalities could not prevent all thromboembolic complications. In our study combined treatment was the most effective one.

[Perforated peptic ulcers]

Two hundred forty-eight patients were operated for perforated peptic ulcer between 1983 and 1998. Of the patients 112 (45.1%) had chronic, 34 (13.7%) had acute ulcer history and 102 (41.2%) had no ulcer history. Of the patients 228 (92.0%) had duodenal, 9 (3.6%) had juxtapyloric, 6 (2.4%) had marginal, and 5 (2.0%) had antral ulcer. Forty two patients (16.9%) admitted within 12 hours and 206 patients (83.1%) between 12 hours and six days after perforation. Simple closure and omental patch was performed in 32 patients (12.9%) who had severe concomitant illness and 126 (50.8%) intraabdominal sepsis, truncal vagotomy + pyloroplasty in 32 (12.9%), simple closure + omental patch + truncal vagotomy + gastroenterostomy in 34 (13.7%), simple closure + omental patch + parietal cell vagotomy in 21 (8.5%), truncal vagotomy + antrectomy in 3 (1.2%). Patients who didn't have definitive procedure received H2 receptor blockers or proton pomp inhibitors. One hundred ninety-three patients (77.8%) underwent endoscopic control. Two of 53 patients with definitive procedure (3.8%) and 34 of 140 patients (24.3%) with simple closure had recurrence. Two patients in simple closure group underwent parietal cell vagotomy, the others received medical treatment. The recurrence rate was significantly higher in simple closure group (p < 0.01).

Surgical treatment of hydatid disease of the liver: review of 304 cases

HYPOTHESIS

To review the results of different modalities of treatment of hydatid disease of the liver.

DESIGN

Retrospective study of 304 patients.

SETTING

A university hospital in Turkey.

PATIENTS

Three hundred four patients with hepatic hydatid disease who underwent operation between 1981 and 1996.

MAIN OUTCOME MEASURES

Mortality and morbidity.

RESULTS

Two hundred thirty-eight patients had a cyst on the right lobe, 41 patients had a cyst on the left lobe, and 25 patients had a cyst on both lobes. Forty-five patients had multiple hepatic cysts and 18 patients had coexisting cysts in other intra-abdominal organs. Surgical procedures were tube drainage, capitonnage, omentoplasty, cystectomy, segmentectomy, and cystoenterostomy. Of the patients with tube drainage, 36 developed an infection of the remaining cavity, 10 developed long-lasting biliary fistula, 8 developed cholangitis, and 6 developed septicemia. Four patients died of unreleated complications. Of the patients with capitonnage, 7 developed cholangitis and 3 developed an infection of the remaining cavity. Of the patients with omentoplasty, 1 developed an infection of the remaining cavity and 1 developed cholangitis. One patient who underwent segmentectomy developed pulmonary complications. Of the patients with cystoenterostomy, 1 developed cholangitis, 1 developed septicemia, and 1 developed pulmonary complications.

CONCLUSION

For management of hydatid disease of the liver, capitonnage, omentoplasty, cyst excision, segmentectomy, or cystoenterostomy are all superior to tube drainage.

Long-term effects of alprazolam on memory: a 3.5 year follow-up of agoraphobia/panic patients

BACKGROUND

Benzodiazepines (BZs) can impair explicit memory after a single dose and also when taken repeatedly for treatment of anxiety disorders. A previous study with agoraphobia/panic patients found that the BZ alprazolam impaired memory during an 8-week treatment and residual impairments were still manifest several weeks after drug withdrawal (Curran et al. 1994). The present study followed up the same group of patients 3.5 years after treatment to determine whether those memory impairments persisted.

METHOD

Thirty-one patients, 15 who had originally been treated with alprazolam and 16 with placebo, were assessed on a battery of psychometric tests and self-rating scales.

RESULTS

Ex-alprazolam patients performed at the same levels as ex-placebo patients on the memory task and on other objective tests. Performance levels of both groups were similar to pre-treatment baselines, however there were differences in subjective ratings whereby ex-alprazolam patients rated themselves as less attentive and clear headed and more incompetent and clumsy than ex-placebo patients.

CONCLUSIONS

Explicit memory impairments found while patients were taking alprazolam and weeks after drug withdrawal did not persist 3.5 years later. We suggest that the memory impairments observed in our previous study weeks after withdrawal of alprazolam were not residual effects of alprazolam but rather were due to the drug's interference with practice effects on the tests and habituation of anxiety over repeated exposure to the test situation.

Psychological preparedness for trauma as a protective factor in survivors of torture

BACKGROUND

Although much research has focused on mechanisms of traumatization and factors related to post-trauma psychological functioning in survivors of trauma, there have been few studies of survivors of torture despite the widespread practice of torture in the world. The aim of this study was to examine the role of 'psychological preparedness' for trauma in post-traumatic stress responses in survivors of torture.

METHOD

Thirty-four torture survivors who had no history of political activity, commitment to a political cause or group, or expectations of arrest and torture were compared with 55 tortured political activists, using structured interviews and measures of anxiety, depression, and post-traumatic stress disorder.

RESULTS

Compared with tortured political activists, tortured non-activists were subject to relatively less severe torture but showed higher levels of psychopathology. Less psychological preparedness related to greater perceived distress during torture and more severe psychological problems, explaining 4% of the variance in general psychopathology and 9% of the variance in post-traumatic stress disorder symptoms.

CONCLUSIONS

The study findings lend support to the role of prior immunization to traumatic stress and to unpredictability and uncontrollability of stressors in the effects of traumatization. Further research aimed at identifying the behavioural and cognitive components of psychological preparedness that play a role in traumatization may provide useful insights into effective treatment strategies for survivors of torture.

Fournier's gangrene: review of fifteen cases

Fournier's gangrene is a synergistic necrotizing fasciitis of the perineum and abdominal wall along with the scrotum and penis in men and the vulva in women. The process was believed to be idiopathic in initial descriptions. Fifteen patients were treated for Fournier's gangrene between 1990 and 1995 in the Departments of General Surgery and Urology, School of Medicine, Atatürk University, Erzurum, Turkey. The most common causes were perianal sepsis and urogenital diseases. Escherichia coli and Staphylococcus aureus were identified most commonly in cultures of necrotic tissue. The mortality rate was 20 per cent despite aggressive surgical debridement and broad-spectrum antibiotics.

Double-blindness procedures, rater blindness, and ratings of outcome. Observations from a controlled trial

BACKGROUND

We determined whether blindness in a double-blind randomized controlled trial of alprazolam and exposure therapies in patients with panic disorder and agoraphobia was maintained in assessors and patients, what were the factors related to "unblinding," and whether unblinding was associated with clinical outcome.

METHOD

In 129 patients with panic disorder and agoraphobia who were randomized to alprazolam-exposure, placebo-exposure, alprazolam-relaxation, or placebo-relaxation conditions, blindness was tested at the end of treatment by the independent assessors' and patients' classification of the treatment condition.

RESULTS

Assessors' classifications were correct in 82% of the alprazolam group and 78% of the placebo group; corresponding figures for patients' classifications were 73% and 70%, respectively. Factors associated with unblinding included drug side effects but not assessors' ratings of treatment outcome.

CONCLUSION

Judgment of the validity of the outcome of a randomized controlled trial is easier if the report notes not only the use of a double-blindness procedure but also details how blind the raters remained and how any unblinding affected their ratings of clinical outcome.

Glutathione and nitric oxide concentrations in glutamine-infused rabbits with intestinal ischaemia/reperfusion

Intestinal ischaemia/reperfusion causes formation of reactive oxygen intermediates which lead to mucosal cell injury. Glutathione, a scavenger of reactive oxygen intermediates, protects tissues from reactive oxygen intermediate-mediated cell injury. Nitric oxide is a lipophilic gas and its synthesis is stimulated by ischaemic conditions. In this experimental study, we aimed to investigate the role of i. v. L-glutamine infusion on mucosal tissue glutathione and serum nitric oxide concentrations in intestinal ischaemia/reperfusion. External jugular vein of albino rabbits was cannulated with catheter and infused with normal saline at 4 ml/h. After 3 days, they were randomly divided into two main groups. Group 1 (n = 30) received i. v. normal saline alone, group 2 (n = 30) received normal saline + 205 mmol/l glutamine at 4 ml/h for 24 hours. Next, mucosal glutathione and serum nitric oxide concentrations were measured after 0, 30, 60 min of ischaemia/60 min of reperfusion. Basal glutathione concentrations were similar in normal saline alone and normal saline + 205 mmol/l glutamine infusion groups (p > 0.05). At 30 and 60 min of ischaemia/60 min of reperfusion, glutathione concentrations were significantly lower in normal saline-infused rabbits compared to the normal saline + 205 mmol/l glutamine-infused rabbits (p < 0.05). In addition, serum nitric oxide concentrations were found to be significantly increased in rabbits 30 and 60 min after ischaemia/reperfusion when compared to mean basal nitric oxide concentrations obtained from control animals. However, the normal saline + 205 mmol/l glutamine group had lower serum nitric oxide concentrations than did the normal saline alone group. In conclusion, this study revealed that intestinal mucosal glutathione concentrations were significantly higher in glutamine-receiving rabbits than in non-receiving ones. Additionally, it was shown that nitric oxide concentrations increased in ischaemia both in normal saline alone and normal saline + 205 mmol/l glutamine receiving groups, while this increase in nitric oxide was more prominent in the normal saline alone group (p < 0.01). These findings show that glutamine supplementation may protect the small intestine from ischaemia/reperfusion injury and may play a regulatory role in the biosynthesis of nitric oxide.

Agoraphobia and panic disorder: 3.5 years after alprazolam and/or exposure treatment

BACKGROUND

Long-term follow-ups after controlled studies of exposure therapy for agoraphobia/panic are few. Most of these studies found that improvement during treatment persists to the end of follow-up.

METHODS

Out of 69 patients with panic disorder plus agoraphobia who had been in an 8-week controlled study of alprazolam and/or exposure, 31 were followed up at a mean of 3.5 years later (4 years after trial entry). The 31 patients followed up included more cases who had relapsed at week 43 than did the group which did not attend the 3.5-year follow-up.

RESULTS

As a group, followed-up cases maintained their gains over the 3.5 years, more so among ex-exposure than ex-relaxation cases. Ex-exposure patients did significantly better than relaxation patients on disability and survival time. Ex-alprazolam and ex-exposure patients did not differ significantly on any variable at the 3.5-year follow-up. No baseline variable predicted outcome at follow-up.

CONCLUSIONS

Present results modestly confirm those of previous studies finding lasting improvement years after exposure, though some residual symptoms were the norm.

Appraisal of self, social environment, and state authority as a possible mediator of posttraumatic stress disorder in tortured political activists

This study examined appraisal of self and others, as measured by semantic differential ratings of Police, State, Society, Family, Friend, Myself as a Man/Woman, and Myself as a Political Person, in 55 tortured political activists in Turkey, 55 nontortured political activists, and 55 nontortured, politically noninvolved controls. There were no remarkable differences between tortured and nontortured political activists; both groups differed from controls in having a more negative appraisal of the police and the state and stronger perceptions of danger, mistrust, and injustice in relation to state authority. Lack of beliefs concerning a "benevolent state" may have protected the survivors from the traumatic effects of state-perpetrated torture. Further research into the possible protective role of belief systems in posttraumatic stress disorder is needed.

Does exposure to internal cues enhance exposure to external cues in agoraphobia with panic? A pilot controlled study of self-exposure

BACKGROUND

The value of internal (interoceptive) cues for exposure is under debate and so was tested in a pilot controlled study.

METHODS

Outpatients with panic disorder and severe agoraphobia were randomised to 10 weeks of self-exposure to either (1) both internal (interoceptive) and external cues (n = 12) or (2) external cues only (n = 14). Both groups were trained in slow deep breathing and asked to carry out daily self-exposure homework. Neither group had cognitive restructuring.

RESULTS

By post-treatment and follow-up all outcome measures improved significantly in both treatment groups. The two groups did not differ significantly in outcome, though slightly more patients who had exposure to both internal and external cues improved 50% or more on phobic avoidance and fear.

CONCLUSIONS

A larger controlled study is now worthwhile to tell if such small differences can be significant.

Factors related to long-term traumatic stress responses in survivors of torture in Turkey

OBJECTIVE

To examine factors related to long-term psychological functioning in political ex-prisoners who had been subjected to systematic torture.

DESIGN

The psychological status of 55 tortured political activists, 55 nontortured political activists, and 55 subjects with no history of torture or political activism was assessed using Structured Clinical Interview for DSM-III for psychiatric assessment, Semi-structured Interview for Survivors of Torture, and other self-rated and assessor-rated measures of anxiety, depression, and posttraumatic stress disorder (PTSD). Correlational and multiple regression analyses were used to assess the independent effects of precaptivity, captivity, and postcaptivity variables as predictors of long-term psychological status among the torture survivors.

SETTING

Istanbul, Turkey.

MAIN OUTCOME MEASURES

Number of lifetime and current PTSD symptoms, and scores on the Beck Depression Inventory, Hamilton Depression Rating, Hamilton Anxiety Scale, and State-Trait Anxiety Inventory.

RESULTS

Effect of captivity experience on various life areas (eg, family and social, economic, and employment status) and other postcaptivity psychosocial stressors were associated with PTSD symptoms, anxiety, and depression. Perceived severity of torture was related to PTSD symptoms but not to anxiety or depression. Lack of social support predicted anxiety and depression but not PTSD. Family history of psychiatric illness correlated with higher scores on most measures. Impact of captivity experience on family was the strongest predictor of PTSD symptoms.

CONCLUSIONS

These findings point to three types of stressors related to different aspects of psychopathology in survivors of torture: perceived severity of torture, secondary effects of captivity experience on various life areas, and general psychosocial stressors following captivity. Different interventions may be needed for three components of survivors' traumatic experience: cognitive and behavioral strategies for treatment of PTSD symptoms, marital or family strategies for minimizing the impact of the trauma on the family, and strategies for enhancing social support to minimize postcaptivity depression and anxiety.

Safety and side-effects of alprazolam. Controlled study in agoraphobia with panic disorder

BACKGROUND

The widespread use of benzodiazepines has led to increasing recognition of their unwanted effects. The efficacy of alprazolam and placebo in panic disorder with agoraphobia, and the side-effect and adverse effect profiles of both drug groups were measured.

METHOD

In London and Toronto 154 patients who met DSM-III criteria for panic disorder with agoraphobia were randomised to alprazolam or placebo. Subjects in each drug group also received either exposure or relaxation. Treatment was from weeks 0 to 8 and was then tapered from weeks 8 to 16.

RESULTS

Mean alprazolam dose was 5 mg daily. Compared with placebo subjects, alprazolam patients developed more adverse reactions (21% v. 0%) of depression, enuresis, disinhibition and aggression; and more side-effects, particularly sedation, irritability, impaired memory, weight loss and ataxia. Side-effects tended to diminish during treatment but remained significant at week 8. Despite this, the drop-out rate was low.

CONCLUSIONS

Alprazolam caused side-effects and adverse effects during treatment but many patients were willing to accept these.

Alprazolam and exposure for panic disorder with agoraphobia. Attribution of improvement to medication predicts subsequent relapse

Patients with panic disorder plus agoraphobia had 8 weeks of drug treatment (alprazolam or placebo) plus psychological treatment (exposure or relaxation). At the end of treatment at week 8, 40 patients who had become much/very much improved rated how much their gains were attributable to medication or to their own efforts. During the tapering-off to week 16, and treatment-free follow-up to week 43, patients who at week 8 had attributed their gains to medication and felt less confident in coping without tablets had more severe withdrawal symptoms and greater loss of gains than did patients who at week 8 had attributed their gains to their own efforts during treatment. Baseline illness severity, greater age, higher expectations from drug treatment, and more side-effects of drugs during treatment all predicted more external attributions (i.e. to the effect of drugs) but did not independently predict relapse. Patients on alprazolam compared with placebo had more drug attributions. Though drug attributions predicted relapse in both alprazolam and placebo groups, predictions were stronger in the alprazolam group.

Relationship of panic, anticipatory anxiety, agoraphobia and global improvement in panic disorder with agoraphobia treated with alprazolam and exposure

In a controlled trial of alprazolam and exposure in 154 patients with panic disorder with agoraphobia, relations between panic, anticipatory anxiety, and phobic avoidance were examined. The three symptoms were independent of one another at baseline and improved largely independently during treatment; only early improvement in avoidance predicted global improvement after treatment. Global improvement was more related to reduction of avoidance than a decrease in panics. Panic was not a valuable outcome measure in panic disorder with agoraphobia.

Pre-treatment predictors of treatment outcome in panic disorder and agoraphobia treated with alprazolam and exposure

Pre-treatment predictors of treatment outcome were examined in a group of 144 patients with panic disorder and agoraphobia randomly allocated to alprazolam+exposure (AE), placebo+exposure (PE), alprazolam+relaxation (AR), and placebo+relaxation (PR). First-time psychotropic medication use, severity of agoraphobic disability, and longer duration of illness predicted less global improvement at post-treatment. Pre-treatment severity of agoraphobia predicted less improvement both in the short- and the long-term. Predictors of poorer outcome at 6-month follow-up were older age, past history of depression, severity of phobia targets, and longer duration of illness. Sex, source of referral, pre-treatment depression-anxiety-panic, and expectancy from treatment did not relate to outcome.

A cross-cultural comparative study of depressive symptoms in British and Turkish clinical samples

A cross-cultural comparison of the symptomatology of depression in Britain and Turkey was conducted in outpatient samples selected according to the same criteria, and matched for age, sex and severity; the same standardized rating instruments were also used with each sample. Comparison of the frequency and severity of individual symptoms showed higher mean ratings in the British sample for core depressive symptoms and higher ratings in the Turkish sample for symptoms reflecting somatization and a tendency to emphasize symptoms. Principal component analysis produced similar dimensions, confirmed after factor rotation, but the principal components emerged in a different order, reflecting differing contributions to the variance. In the Turkish sample, the first, general component, accounting for the greatest variance, was the somatization factor, while in the British sample it was the component that reflects core depressive symptoms. These findings indicate that there are some similarities in the symptoms of depression in the two cultures, but also differences in their predominant mode of expression.

Psychological effects of torture: a comparison of tortured with nontortured political activists in Turkey

OBJECTIVE

The aim of the study was to investigate the long-term effects of torture in a group of former political prisoners.

METHOD

The study was carried out in Istanbul, Turkey, where 55 Turkish political activists who had been tortured were compared with a closely matched group of 55 activists who had not been tortured. The Structured Clinical Interview for DSM-III-R, the Semistructured Interview for Survivors of Torture, and other self-rated and assessor-rated measures of anxiety, depression, and posttraumatic stress disorder (PTSD) were used. The tortured and the nontortured activists were similar in age, sex, marital and socioeconomic status, political ideology, political involvement, stressful life events other than torture, and other features.

RESULTS

The torture survivors reported an average of 291 exposures to a mean of 23 forms of torture. The mean length of their imprisonment was 47 months. The survivors of torture had significantly more symptoms of PTSD and anxiety/depression than the nontortured comparison subjects, although their PTSD symptoms were only moderately severe and their general mood was normal. Despite the severity of their torture experiences, the survivors had only a moderate level of psychopathology.

CONCLUSIONS

The results suggest that torture has long-term psychological effects independent of those related to uprooting, refugee status, and other traumatic life events in a politically repressive environment. Prior knowledge of and preparedness for torture, strong commitment to a cause, immunization against traumatic stress as a result of repeated exposure, and strong social supports appear to have protective value against PTSD in survivors of torture.

Prevention of torture and care of survivors. An integrated approach

An analysis of the 1992 Amnesty International report demonstrates the nature and global distribution of reports of human rights violations. Systematic torture was reported in 93 of 204 countries. Reports of torture were more common from regions affected by political unrest, including mass demonstrations, riots, outbreaks of violence, killings, coup attempts, civil war, armed tribal conflict, rebellions, and conflicts with various opposition groups demanding social and political reform. These observations suggest that effective measures against torture require a multilevel analysis of underlying social, political, cultural, and psychological factors. Effective care of survivors of organized violence and torture is an indispensable component of the human rights struggle and needs more scientific attention. An integrated approach involving both preventive efforts and care of survivors can promote the human rights cause.

Alprazolam and exposure alone and combined in panic disorder with agoraphobia. A controlled study in London and Toronto

A cross-national randomised trial of alprazolam for chronic panic disorder with agoraphobia was run. Compared with previous trials it had three new features: an exposure therapy contrast group, a six-month treatment-free follow-up, and a low rate of early placebo drop-outs ('non-evaluables'). The dose of alprazolam was high (5 mg/day). The 154 patients had eight weeks of: alprazolam and exposure (combined treatment); or alprazolam and relaxation (a psychological placebo); or placebo and exposure; or placebo and relaxation (double placebo). Drug taper was from weeks 8 to 16. Follow-up was to week 43. Results were similar at both sites. Treatment integrity was good. All four treatment groups, including double placebo, improved well on panic throughout. On non-panic measures, by the end of treatment, both alprazolam and exposure were effective, but exposure had twice the effect size of alprazolam. During taper and follow-up, gains after alprazolam were lost, while gains after exposure were maintained. Combining alprazolam with exposure marginally enhanced gains during treatment, but impaired improvement thereafter. The new features put previous trails in a fresh light. By the end of treatment, though gains on alprazolam were largely as in previous studies, on phobias and disability they were half those with exposure. Relapse was usual after alprazolam was stopped, whereas gains persisted to six-month follow-up after exposure ceased. Panic improved as much with placebo as with alprazolam or exposure.

A prospective study of panic and anxiety in agoraphobia with panic disorder

The features of panic and anxiety in the natural environment were studied by prospective self-monitoring in 39 patients with chronic agoraphobia and panic disorder. Panics overlapped greatly with anxiety episodes but were more intense. Panics occurred more often in public places than did anxiety episodes, but had otherwise similar symptom profile, time of occurrence, and antecedents. Most panics surged out of a pre-existing plateau of tonic anxiety which lasted most of the day. Spontaneous panics were less frequent than situational panics and occurred more often at home but were otherwise similar. These findings do not support the sharp distinction between panic and anxiety in DSM-III-R, not its emphasis on spontaneous panic in classifying anxiety disorders. Thoughts of dying and 'going crazy'/losing control accompanied only a minority of panic/anxiety episodes and seemed to be a product of intense panic rather than a cause.

Obsessive-compulsive beliefs and treatment outcome

Of 49 compulsive ritualizers one-third perceived their obsessive thoughts as a rational and felt that their rituals warded off some unwanted or feared event (the content of their obsessions). The more bizarre the obsessive belief the more strongly it was defended and 12% of cases made no attempt to resist the urge to ritualize. Neither fixity of belief nor resistance to compulsive urges were related to duration of illness. Patients with bizarre and fixed obsessive beliefs responded as well to treatment (all but three received exposure), as did patients whose obsessions were less bizarre and recognized as senseless. There was no difference in outcome between patients who initially found it hard to control their obsessions or never resisted the urge to ritualize and those who initially could control obsessions or resist rituals. One year after starting treatment, patients whose obsessions and compulsions had improved with treatment recognized their irrationality more readily and controlled their compulsive urges more easily.

Symptomatology of depressive disorder in Turkey. A factor-analytic study of 100 depressed patients

The clinical interview for depression and the Hamilton Rating Scale were administered to a sample of 100 Turkish depressed outpatients who satisfied the research diagnostic criteria for major depression. Ratings were made on a semi-structured interview covering 38 items with closely defined anchor points. Historical data relevant to depressive illness were also recorded. Principal component analysis yielded four clinically meaningful factors. The endogenous-neurotic dimension emerged as a bipolar factor and the bimodal distribution of patients' scores on this factor indicated two distinct groups. The results were compared with other factor-analytic studies and cross-cultural differences were discussed.
