Platelet monoamine oxidase (MAO) activities were assessed in 82 patients, 57 females and 25 males, who were admitted to the medical ward of a general hospital after a suicide attempt. The enzyme activities were compared to the activities of healthy subjects, 35 females and 26 males. In addition, MAO activities were analyzed in relation to sex, psychiatric diagnosis, mode of attempt, drugs ingested, and previous attempts. Compared to normal controls, only female patients showed lower MAO activities. In the male population, lower activities were found in the subgroup of patients who had made previous attempts. In relation to diagnosis, analysis performed in the female population revealed lower MAO activities in the dysthymic and personality disorder, and not in the adjustment or major affective disorder subgroups. MAO activities were not related to the violent mode of attempt, the type of medication used, or the score in the Beck Suicidal Intent scale. The finding of low platelet MAO activities in dysthymic disorder, indicates the need for further studies of biological variables in this underdiagnosed and undertreated diagnostic group.
Telepsychiatry was introduced in the early 1950's for the provision of mental health services from a distance. In 1990 the progress made in telecommunications technologies caused a significant expansion in telepsychiatry services. It can refer to store and forward technologies, interactive technologies, remote monitoring technologies and it is applied to contribute to the lift of restrictions placed on providing mental health services. Restrictions may exist due to geographic isolation, lack of specialized services, high cost of moving patients etc. The positive cost-benefit analysis and the reliability of diagnosis and efficacy of interventions through telepsychiatry have been documented in various research papers referring to a wide range of contexts such as prisons, remote areas, general and psychiatric hospitals. Since 2003 the Mobile Mental Health Unit of South- Eastern (SE) Cyclades has been using videoconferencing in order to provide mental health services in thirteen islands. This area shares many of the characteristics of remote areas such as residential dispersion, lack of mental health services and frequent lack of access to services in urban centers. Telepsychiatry in conjunction with physical presence of professionals was launched by the Mobile Mental Health Unit in order to provide assistance to the evaluation of patients, to therapeutic interventions, to medicine prescription, to crisis intervention, to psychoeducation of patients and their families and to the implementation of educational and administrative activities . The use of existing technology in combination with the development of human resources has enabled continuity of care, crisis intervention and avoidance of involuntary hospitalization for a significant number of persons. Moreover, it has improved cooperation and coordination between the interdisciplinary team and local authorities and agencies. When professionals located in different parts are collaborating via telepsychiatry it is necessary to ensure that they have immediate and simultaneous access to data concerning the patient. This need is served by the electronic medical record that facilitates access to patient records, improves the quality of care, reduces the probability of making wrong decisions and contributes to the promotion of research and service evaluation. KLIMAKA's electronic medical record contains more than ten thousand cases of which 4544 are related to individuals served by the Mobile Mental Health Unit during the years 2003-2010. This article presents the basic functions and parameters of the electronic medical record, the applications of telepsychiatry in the whole range of services provided by the scientific staff and provides information on how human and technology resources are distributed to the branches of the Mobile Mental Health Unit of SE Cyclades.
Resumen La investigación de los correlatos biológicos del comportamiento suicida es importante para identificar a los sujetos de alto riesgo. El objetivo de este estudio era examinar las variables neuroquímicas de la actividad de la MAO de las plaquetas y los niveles en la orina del MHPG, el 5HIAA y el HVA, los metabolitos principales de la noradrenalina, la serotonina y la dopamina, neurotransmisores a los que se considera implicados en la patofisiología del comportamiento suicida, así como el cortisol en plasma, en un grupo de sujetos con trastorno adaptativo después de un intento de suicidio. Se incluyó en el estudio a 53 pacientes, 42 mujeres y 11 varones, y se los comparó con un grupo de 50 controles sanos, 25 mujeres y 25 hombres. Se encontró que la actividad de la MAO de las plaquetas era significativamente más baja tanto en los pacientes masculinos como femeninos comparado con los controles del mismo sexo (P < 0,001 para ambas comparaciones). El 5HIAA y el HVA no fueron diferentes entre los pacientes y los controles, pero el MHPG fue significativamente más alto en el grupo de pacientes (P = 0,008). Además, los niveles de cortisol en plasma fueron significativamente más altos en los pacientes comparado con los controles (P < 0,001). Nuestros resultados confirman la hipótesis de la baja actividad de la MAO de las plaquetas como una característica biológica de los pacientes que intentan suicidarse. También señalan una posible activación paralela del sistema noradrenérgico.
A placebo-controlled, double-blind study of 63 inpatients with major affective disorder was performed to compare the safety and efficacy of fluvoxamine and imipramine. Results indicate that fluvoxamine and imipramine are superior to placebo and demonstrate a trend toward superiority of fluvoxamine over imipramine. Fluvoxamine was generally well tolerated in most patients.
Forty-three out-patients with depression of a moderate degree were enrolled in a randomized, double-blind parallel group study comparing amitriptyline and alprazolam for 6 weeks of treatment. Patients were evaluated at the end of placebo washout and at Weeks 1, 2, 3 and 6 of drug therapy using the Hamilton Depression Rating Scale (HAM-D), Hamilton Anxiety Rating Scale (HAM-A), Beck Depression Inventory (BDI) and Clinical Global Impression (CGI). Drug dosage was determined in a fixed-flexible design resulting in mean final doses of alprozalam 3.2 mg/day and of amitriptyline 115 mg/day. Although both drug groups improved there were statistically significant differences in favour of amitriptyline at the end of the study on the HAM-D, BDI and HAM-A scales. Patients on amitriptyline reported more side effects overall than patients taking alprazolam with significantly more reports of dry mouth in the amitriptyline group.
In this study we investigated 1) the changes in anxiety, depression and denial from admission to discharge in patients admitted to the intensive care unit following an acute myocardial infarction and 2) the effect of smoking habits, time lapsed from the appearance of symptoms to seeking help behavior, presence of a person that motivated the patient to seek help, previous myocardial infarction (MI) and family history of MI, on these changes. The results indicated that 1) the levels of both anxiety and depression increased from admission to discharge, while denial decreased; 2) positive family history of MI was associated with lower difference of denial between admission and discharge.
The investigation of biological correlates of suicidal behavior is important for identifying high-risk subjects. The objective of this study was to examine the neurochemical variables' platelet MAO activity and urinary MHPG, 5HIAA and HVA, the main metabolites of noradrenaline, serotonin and dopamine, neurotransmitters that are considered to be involved in the pathophysiology of suicidal behavior, as well as plasma cortisol, in a group of subjects with adjustment disorder after a suicide attempt. Fifty-three patients, 42 females and 11 males, were included in the study and were compared to a group of 50 healthy controls, 25 females and 25 males. Platelet MAO activity was found to be significantly lower in both male and female patients compared to controls of the same sex (P < 0. 001 for both comparisons). 5HIAA and HVA were not different between patients and controls, but MHPG was significantly higher in the patients group (P = 0.008). Moreover, plasma levels of cortisol were significantly higher in the patients compared to the controls (P < 0. 001). Our results confirm the hypothesis of low platelet MAO activity as a biological characteristic of patients who attempt suicide. They also point to a possible parallel activation of the noradrenergic system.
