Eating disturbances in siblings of patients with eating disorders.

OBJECTIVE: The purpose of this study was to investigate whether siblings of patients with eating disorders show a more disturbed eating behavior and a higher proneness to associated psychological characteristics than controls. METHOD: 84 patients with eating disorders of an outpatient clinic, their siblings (n=84) and a control group (n=84) with an age range 14-34 for the total sample were evaluated using the Eating Disorder Inventory-2. RESULTS: There was no significant difference between the siblings and the controls in disturbed eating behavior. DISCUSSION: The existence of an eating disorder in patients does not seem to be related to the development of eating disturbed behavior in their siblings.

[Bulimia nervosa in homosexuality and HIV infection in the man. Case report].

A male with bulimia nervosa is reported whose homosexual behavior resulted in HIV infection. The goal of this case study is to shed light on the course characteristics of bulimia nervosa occurring together with HIV infection in connection with homosexuality. The patient had experienced a number of traumas including sexual abuse, which surely had an influence on his developing bulimia nervosa. His longing for slimness, shown by the excessive preoccupation and dissatisfaction with body shape and weight may be considered typical for bulimia nervosa in homosexual men. Furthermore, male subjects with eating disorders often seem to be overweight prior to the start of bulimia nervosa, which also was the case in this subject. The course of his HIV infection so far has had no effect on severity of the bulimic symptoms. However, his bulimia nervosa apparently did had negative effects on the course of the HIV infection.

Gender differences in adolescents and young adults with suicidal behaviour.

OBJECTIVE: Gender differences in prevalence rates of suicide attempts and suicidal thoughts as well as in risk factors for suicide attempts such as traumatic events and mental disorders were investigated in a random sample of 3021 adolescents aged 14-24 years. METHOD: The M-CIDI (Composite International Diagnostic Interview) was used to survey suicidal behaviour, DSM-IV lifetime diagnoses and traumatic events. RESULTS: The female suicide attempters showed suicidal thoughts and suicide attempts significantly more often, and suicide attempts at a much younger age than the males. Furthermore, the females experienced sexual abuse much more often, and suffered significantly more often from anxiety disorders. The male suicide attempters showed higher rates of alcohol disorders and financial problems. CONCLUSION: A higher rate of anxiety in female suicide attempters results probably as a consequence of sexual abuse, which in turn makes them more vulnerable than males for attempting suicide between the age of 14-17.

Comorbidity in primary care: presentation and consequences.

Comorbidity is a well-established phenomenon in depressive disorders, and it is widely agreed that the majority of depressive disorders examined in both primary care and the general population are not "pure." This article reviews comorbidity findings in general population and primary care surveys. The implications of comorbid depressive disorders are discussed in terms of their presentation and recognition in primary care, patterns of course and outcome, and associated impairments and disabilities. Data from a World Health Organization study, conducted in primary health clinics in 15 countries, demonstrate that 62% of all depressive cases also suffer from at least one other current mental disorder and that the primary reason for patient visits is rarely of a psychological nature, with the majority of attendees complaining primarily of somatic symptoms (41%), pains (37%), and fatigue and sleep problems (12%). Similar results are presented from 2 recent large representative population surveys, the National Comorbidity Survey and the Early Developmental Stages of Psychopathology Study. The implications of such comorbidity are viewed from various perspectives: the form of depressive presentations in primary care, the recognition of depression in health care, and health services utilization, impairments and disabilities, and course and outcome.

Test-retest reliability of the computerized DSM-IV version of the Munich-Composite International Diagnostic Interview (M-CIDI).

The structure and content of the Munich-Composite International Diagnostic Interview (M-CIDI) for the assessment of DSM-IV symptoms, syndromes, and diagnoses is described along with findings from a test-retest reliability study. A sample of 60 community respondents were interviewed twice independently by trained interviewers with an average time interval of 38 days between investigations. Test-retest reliability was good for almost all specific DSM-IV core symptom questions and disorders examined, with kappa values ranging from fair for two diagnoses--bulimia (kappa 0.55) and generalized anxiety disorder (kappa 0.45)--to excellent (kappa above 0.72) for all other anxiety disorders and alcohol use disorders. Test-retest reliability for age of onset and time-related questions was fairly consistently high (intra-class correlation values of 0.79 or above), with one notable exception: the assessment of disorders with onset before puberty. We concluded that the M-CIDI is acceptable for respondents, efficient in terms of time needed for and ease of administration, and reliable in terms of consistency of findings over time periods of at least 1 month.

Comorbidity patterns in adolescents and young adults with suicide attempts.

The role of comorbidity as a risk for suicide attempts is investigated in a random sample of 3021 young adults aged 14-24 years. The M-CIDI, a fully standardized and modified version of the Composite International Diagnostic Interview, was used for the assessment of various DSM-IV lifetime and 12-month diagnoses as well as suicidal ideation and suicide attempts. Of all suicide attempters, 91% had at least one mental disorder, 79% were comorbid or multimorbid respectively and 45% had four or more diagnoses (only 5% in the total sample reached such high levels of comorbidity). Suicide attempters with more than three diagnoses were 18 times more likely (OR = 18.4) to attempt suicide than subjects with no diagnosis. Regarding specific diagnoses, multivariate comorbidity analyses indicated the highest risk for suicide attempt in those suffering from anxiety disorder (OR = 4.3), particularly posttraumatic stress disorder followed by substance disorder (OR = 2.2) and depressive disorder (OR = 2.1). Comorbidity, especially when anxiety disorders are involved, increases the risk for suicide attempts considerably more than any other individual DSM-IV diagnoses.

Structure, content and reliability of the Munich-Composite International Diagnostic Interview (M-CIDI) substance use sections.

After reviewing currently available diagnostic assessment instruments for substance use disorders this paper describes the format and structure of the Munich-Composite International Diagnostic Interview (M-CIDI) substance disorder section. In addition, the test-retest reliability of diagnoses and criteria for nicotine, alcohol, illegal and prescription drugs, is reported. Findings obtained in community sample of adolescents and young adults indicate that the substance section is acceptable for almost all types of respondents, efficient in terms of time and ease of administration as well as reliable in terms of consistency of findings over time. The test-retest reliability over a period of an average of 1 month, as examined by two independent interviewers indicates good-to-excellent kappa values for all substance disorders assessed, with significant kappa values ranging between 0.55 for drug abuse and 0.83 for alcohol abuse. There was also fairly consistently high agreement for the assessment of single DSM-IV diagnostic criteria for abuse and dependence as well as the M-CIDI quantity-frequency and time-related questions. To conclude, although - unlike previous studies - this study was conducted in a community sample and not in patients and used considerably longer time intervals of more than a month between investigations, our M-CIDI reliability findings are at least as high as those from previous studies.

A case of classical mycosis fungoides associated with human T-cell lymphotropic virus type I.

A 72-year-old male patient from north-eastern Iran developed the typical clinical and histopathological features of mycosis fungoides with lymphadenopathy, but without any other systemic involvement. Human T-cell lymphotropic virus (HTLV-I) antibodies were detected in the patient's serum by two different ELISAs and by Western blot using purified viral particles from MT-2 culture supernatants. Cultured peripheral blood lymphocytes were positive for labelling with anti-HTLV-I serum. Southern blot hybridization of DNA extracted from a skin tumour and from an involved lymph node revealed integrated proviral DNA with identical restriction patterns. This case supports a relationship between mycosis fungoides and HTLV-I and may indicate a new region of endemic HTLV-I infection.

[Treatment of venous ulcera cruris with dry wound dressings. Phase overlapping use of silver impregnated activated charcoal xerodressing].

In a controlled randomized study on 40 patients with venous leg ulcers, monotherapy with a dry wound dressing (silver-impregnated--activated charcoal xerodressing; SIAX) was tested. The xerodressing was applied throughout the entire study and was compared with the conventional phase-adapted therapy using diverse topical modalities, e.g. as granulating ointments, zinc paste. etc. The parameters of wound healing were documented in the two randomized groups over 6 weeks and were statistically evaluated. In the statistical comparison of SIAX therapy (n = 19) and conventional therapy (n = 19) significant differences were found in favour of the SIAX group (increase of epithelialization, reduction of ulcer size; P less than 0.05). In addition, the ulcers of 6/19 patients (= 31.6%) treated with SIAX healed completely within the study period, in contrast to only 2/19 patients (= 10.5%) receiving conventional therapy. Exudate, granulation and colonization of the ulcers as well as odour, necroses, erythema and oedema of the surrounding areas were not significantly different. The study shows that a consistent therapy performed with dry wound dressings such as SIAX is superior to the conventional topical therapy of venous leg ulcers in some cases. Wound dressings provide new therapeutic modalities, being easy to apply and fully efficient, without side-effects.

Reversed-phase liquid chromatographic separation and simultaneous fluorimetric detection of polyamines and their monoacetyl derivatives in human and animal urine, serum and tissue samples: an improved, rapid and sensitive method for routine application.

A highly sensitive and precise method for the determination of the polyamines putrescine, cadaverine, spermidine and spermine and all their monoacetyl derivatives in a single analysis in human and animal urine, serum and tissue samples is described. For polyamine separation, an ion-pairing reversed-phase high-performance liquid chromatographic (HPLC) method is used, followed by post-column derivatization with o-phthalaldehyde and consecutive fluorescence detection. Urine and serum samples are purified with a Bond Elut silica cartridge. The detection limit for polyamines is 0.5-1.0 pmol and excellent linearity is achieved in the range from 3 pmol up to more than 10 nmol. The influence of some modifications of different analytical steps such as the temperature of the HPLC column and the derivatization reaction coil and the o-phthalaldehyde flow-rate is described. Quality control data and measurements of the reproducibility of the method are presented. In order to establish a rapid analytical method for easy routine use, all steps for preparation and quantitative analysis are minimized. This method was applied to the determination of total polyamines in human urine and serum hydrolysate and of free and acetylated polyamines in human urine and pancreatic tissue of the rat. Values for normal polyamine concentrations in the urine and serum of fifteen male and fifteen female healthy volunteers and in the pancreas of ten normal rats are presented.

Pancreatic polyamine concentrations and cholecystokinin plasma levels in rats after feeding raw or heat-inactivated soybean flour.

We investigated the trophic effect on the pancreas of male Wistar rats fed up to 20 days with either raw soybean flour (RSF) containing an active trypsin inhibitor or heat-inactivated soybean flour (HSF). The concentrations of the polyamines putrescine, spermidine, and spermine in the pancreas as well as cholecystokinin (CCK) concentrations in arterial and portal vein plasma were measured. Plasma CCK concentrations were measured by a sensitive radioimmunoassay specific for the sulfated region of CCK, whereas polyamine concentrations are determined by reversed phase high-performance liquid chromatography. The levels of CCK in both arterial and portal vein plasma were significantly higher in RSF- compared with HSF-fed rats, the concentration in the portal vein being twice as high compared with the aorta. A significant increase in pancreatic weight and protein content was positively correlated to an increase in putrescine and spermidine in the pancreas of RSF-fed rats compared with HSF-fed controls, whereas the spermine content did not differ between the two groups. The pancreatic DNA content in RSF-fed rats was significantly above control values of day 20 only. These data support the hypothesis that the trophic effect of soybean trypsin inhibitor on the pancreas is mediated by CCK and that polyamines might play an important role in CCK-induced pancreatic growth.
