We shall present the development of a cohort of 40 children aged from 6 to 11 who were initially diagnosed with ADHD (T0) and then reassessed after two years of treatment with multimodal treatment in addition to stimulant medication. At the outset of the study (T0) the children underwent a complete assessment which included a child psychiatric examination, a neuropsychological evaluation of attention skills and a psychodynamic psychological assessment using the T.A.T. and Rorschach projective tests interpreted from a psychoanalytic viewpoint. An identical protocol was used for the reassessment of the children two years later (T2).
Clinically, and from a strictly behavioral point of view, it is clear that there was a calming down of the symptoms associated with the ADHD. Can the same be said for the results of the neuro-psychological and projective tests as well as for the overall psychic functioning of the children?
At this point in our research, and taking into account that T 2 just ended, we can affirm that the children who were assessed with neurotic disorders (according to the classification of psychopathological disorders in childhood) were those who showed the clearest signs of improvement. We shall then study in depth the majority of the population who were assessed with borderline personality disorders (BPD). As these children received a multimodal treatment over the two years time of the study which involved either individual, group or family psychotherapy, we shall use brief clinical case studies for a comparative approach to our research results.

Introduction
High rates of substance abuse have been reported in the general population and users of mental health services. In our environment, relationship between substance abuse and manic phase has not been well characterized.
AimsDetermining the prevalence of active substance abuse among patients admitted to acute mental health unit at Virgen de la Victoria Hospital at Malaga, diagnosed with mania or hipomanía.
MethodsWe analysed urine and blood seeking for ethanol, cannabis and other 11 substances in 140 patients previously diagnosed with bipolar disorder prior to their admission at the Hospital for mania or hipomanía phase.
ResultsThirty-seven percent of the patients were positive for drugs. Eighteen percent were positive for two or more drugs. Males had higher rates of abuse than females, except in MDMA and amphetamines. By subtypes, cannabis (37.2%) and ethanol (29.62%) were the most consumed drugs. In young age cohorts had higher rates of active substance abuse. Dual patients had longer average stays at hospital (2.6 days more) (Fig. 1).
ConclusionsSubstance abuse is a major comorbidity in bipolar patients with manic phase. The active consumption of cannabis and ethanol especially emphasizes in men younger than 35 years.
We believe priority should be given to recognition and multidisclipinary approach to substance use disorders in bipolar patients. Bipolar patients with comorbid substance abuse may have a more severe course, and may be a preventable factor of new relapses. This rate could increase healthcare costs and worse quality of life of these patients.

Introduction
Recently, depot aripiprazole was approved as a maintenance treatment for schizophrenia. However, long-acting antipsychotics has not been established efficacy in manic episode or maintenance treatment of bipolar disorder.
AimsDescribe a clinical case of multiresistant bipolar disorder.
MethodsThirty-nine years old male, diagnosed since 8 years ago with bipolar disorder, current episode manic with psychotic symptoms, admitted to Acute Psychiatrist Unit. It was his seventh internment. He was dysphoric, had insomnia, and showed many psychotic symptoms like grandiose delusions and delusions of reference. He thought he was a famous painter from nineteenth century.
His disorder was refractory to mood stabilizers monotherapy and to many neuroleptic and, like olanzapine 30 mg/day, depot risperidone, zuclopenthixol, haloperidol, palmitate paliperidone, He was on treatment with lithium 1200 mg/day (lithemia 0.62 prior to admission) and oral aripiprazole 15 mg/day that he was not taking regularly. Poor compliance to oral treatment. No awareness of illness.
Resultsduring the patient admission, we started long-acting aripiprazole 400 mg per 28–30 days. First 3 days he persisted dysphoric, hostile, and showing delusions of mind being read. From the fourth day, delusions disappeared and later he was calmer and more friendly, He was discharged 9 days later fully euthymic.
For 6 months follow-up, the patient came once a month to community center for aripiprazole injection and he was taking lithium regularly. Last lithemia 0.65 mEQ/L.
ConclusionLong-acting antipsychotics, like depot aripiprazole could be a useful alternative to oral medication, specially when there is no awareness of illness and there is low adherence to oral treatment.

Introduction
Lack of adherence is a common cause of relapse in schizophrenia. Long-acting antipsychotics have shown in recent studies that they improve compliance. However, some randomised controlled trials showed no difference in relapse rates between oral medication and long-acting injections.
ObjectiveTo report the use of paliperidone palmitate in an Acute Psychiatrist Unit in Spain.
MethodRetrospective observational study of 42 patients prescribed paliperidone palmitate (PLAI) during an admission at Acute Psychiatric unit in Málaga. In the mirror image analysis, the main outcome measure was the total number of days of psychiatric inpatient care twelve months before and after patients started Paliperidone palmitate.
ResultsMost common reason for starting paliperidone palmitate was lack of adherence to oral medication (54%) followed by lack of efficacy on previous medication (31%). Olanzapine (47%) and risperidone (41%) were most commonly antipsychotics prescribed before PLAI. Thirty-four patients continued PLAI over twelve months (80%). Poor compliance was the most common reason of withdrawal. Three patients had a movement disorder adverse effect. Only one was lost because adverse effects. Total admissions and inpatients days were significantly reduced from the previous treatment to PLAI-treatment period (Table 1).
ConclusionPLAI was associated with a reduction in total inpatient days. The financial saving from reduced admissions stays exceeded the acquisition and administration cost of PLAI. Improved compliance because of PLAI is the most plausible explanation of this result (Fig. 1).

Introduction
Patient adherence to a treatment regimen is of utmost importance for successful outcomes in schizophrenia. Long acting aripiprazole (LAA) is a new drug of depot antipsychotic type placed in the market recently that could prevent non-adherence and in reducing relapse in schizoprenia administered every 28 days.
ObjectiveA descriptive, observational study designed to explore the efficacy and tolerability of long acting aripiprazole in a sample of patients diagnosed with paranoid schizophrenia that were admitted to Acute Unit in 2014. LAA was introduced on the admission.
MethodsSociodemographic variables: age, sex, and marital status. Clinical variables: average time since diagnosis, concomitant consumption of toxic substances, reason to change medication, subsequent readmissions after LAA was introduced, evaluation of the modification of the oral regimen. PANSS and CGI. Metabolic profile: weight, glycaemia, and total cholesterol, LDL and HDL, triglycerides. Cost at the beginning and after 6 months.
ResultsMean age: 44.50 years, 54% women. Marital status: 54% single, 27% married, 27% divorced. Mean time from diagnosis: 11 years. Toxic consumption: 27% active, 18% ex-drug users. Three patients were readmitted after introducing LAA, 2 of them were for abandoning medication (including LAA). PANSS at 6 months showed statistically significant differences in negative subscale (3 points). No statistical differences in positive and general psychopathology subscales. No metabolic side effect was found. Average saving per patient 37.05 euros per month (Fig. 1).
ConclusionThis study signalizes that LAA is an effective treatment. Clinically, it has been shown that our patients improve adherence and prevent relapse. Moreover, no metabolic side effects were found. Besides, LAA is also efficient and we would save 407,55 euros per month.

Introduction
Lithium has been widely used as mood stabilizer in bipolar disease, despite its narrow therapeutic range and its side effects. Sodium levels and water consumption could affect lithium renal elimination.
AimsDescribe a lithium intoxication without risk factors and normal kidney function.
MethodsA 71-year-old female, diagnosed with bipolar disorder, current episode euthymic. On treatment with lithium 800 mg/day, 6 months ago she started with hematuria and urologist found a multifocal oncocytoma in left kidney. She was operated with double lumpectomy and partial nephrectomy without complications. Normal preoperative and postoperative renal function. Two months ago, she started with dysarthria, dystonia and coarse tremor, and T wave inversion on the electrocardiogram. In the blood test, lythemia was 1.67 mEQ/L. Creatinine was 0.65 mg/dL. She was admitted to Internal Medicine Unit. She was treated with rehydration by serum. All psychoactive drugs were removed. Twenty days later, lithemia was undetectable in the blood analysis.
ResultsTwo weeks ago, the patient was transferred to the mental health unit due to worsening her mood. Lithium was reintroduced 3 days ago, at doses of 200 mg per day. Today, the patient starts again with symptoms of poisoning by lithium. Lithemia was 1.78.
ConclusionsOn this occasion, partial nephrectomy due to oncocytoma is the most likely cause two consecutive lithium poisonings. Although creatinine and glomerular filtration are in normal range, patients after partial nephrectomy may have a reduced sodium reabsorption in proximal convoluted tubule, which may cause lithium compensatory resorption. This could cause rising in blood lithium levels.

The Cortes geoduck (Panopea globosa) has been considered a Gulf of California (GC) endemic but anecdotal and unpublished evidence has suggested its presence in Bahía Magdalena (BM), on the Pacific coast of southern Baja California. Establishing the identity of geoduck clams and their distribution limits is not only of clear biological significance to understand their structural and functional variation, but is also of consequence for their conservation and management, given the multi-million dollar fishery they support in north-west Mexico. We analysed Panopea clams from Mexican populations, including BM, using an integrative approach including genetics, morphometrics, and an ecological niche model. Our genetic results (restriction fragment length polymorphisms of nuclear ribosomal DNA and mtDNA cytochrome c oxidase subunit I sequences) clearly identify BM geoducks as P. globosa, implying a significant geographical range expansion outside of the GC and refuting its status as endemic to the Gulf. On the other hand, clams from BM were phenotypically different (shell significantly higher) from other Mexican P. globosa and Panopea generosa specimens, which may account for the confusion in their morphological identification. The ecological niche model for P. globosa, integrating ecological and distributional data from the GC, revealed a very low probability (<10%) that this species could successfully occupy BM. Our results and those of others suggest that the Cortes geoduck population in BM may be adapted to specific environmental conditions differing from those experienced by conspecifics inside the Gulf and is likely isolated. This is highly relevant for the management plans of Mexican geoducks.

Background
Prior research on whether marriage is equally beneficial to the mental health of men and women is inconsistent due to methodological variation. This study addresses some prior methodological limitations and investigates gender differences in the association of first marriage and being previously married, with subsequent first onset of a range of mental disorders.
MethodCross-sectional household surveys in 15 countries from the WHO World Mental Health survey initiative (n=34493), with structured diagnostic assessment of mental disorders using the Composite International Diagnostic Interview 3.0. Discrete-time survival analyses assessed the interaction of gender and marital status in the association with first onset of mood, anxiety and substance use disorders.
ResultsMarriage (versus never married) was associated with reduced risk of first onset of most mental disorders in both genders; but for substance use disorders this reduced risk was stronger among women, and for depression and panic disorder it was confined to men. Being previously married (versus stably married) was associated with increased risk of all disorders in both genders; but for substance use disorders, this increased risk was stronger among women and for depression it was stronger among men.
ConclusionsMarriage was associated with reduced risk of the first onset of most mental disorders in both men and women but there were gender differences in the associations between marital status and onset of depressive and substance use disorders. These differences may be related to gender differences in the experience of multiple role demands within marriage, especially those concerning parenting.

The results of photometric and spectroscopic observations of dwarf novae are presented. The data were obtained during an international program of multiwavelength observations, held in 1986 February at several observatories, of dwarf novae during the first and subsequent days of outburst. During the campaign numerous dwarf novae were monitored in order to catch them in outburst. Preliminary results and analysis of some objects are reported elsewhere. A total of 30 dwarf novae were observed in the northern and southern hemispheres. Among them 37% were caught in outburst, including 10% on the rise to outburst and 17% in decline. Photometric observations were carried out in the UBVRI system and colour indexes were calculated.

The ratio of binaries among the WR stars is subject of many discussions essentially due to two reasons: First, the important role that the presence of a companion can play in the evolution of a massive star and as consequence in the interpretation of the evolutionary phase of the WR stars. Second, the strong difficulty to determine the binarity of the WR stars due to the width of the spectral lines.
