Trastorno eréctil ¿Qué factores pueden afectar a su gravedad? Un estudio descriptivo-correlacional / Erectile dysfunction: what factors affect its severity? A descriptive correlate story

Una de las disfunciones sexuales más comunes es el trastorno eréctil (TE). Pretendemos identificar factores asociados a la gravedad del TE. Treinta y seis hombres, entre 18 y 70 años, que presentan un diagnóstico de TE, basado en los criterios DSM-V, han sido evaluados a través de una entrevista clínica y de una batería de 7 cuestionarios (IIEF, SCL-90, PDQ-4, PSWQ, STAI, SSES, SSEI). La metodología se centró en un estudio cuantitativo, de tipo descriptivo-correlacional de diseño ex post facto con muestreo por conveniencia. Los resultados del modelo de regresión final muestran que la autoeficacia sexual, determinadas tendencias de personalidad y la sintomatología de depresión, somatización, obsesión-compulsión y ansiedad son factores asociados a la gravedad del TE, explicando el 51,3% de la varianza. Poder identificar aquellos factores asociados a la gravedad del TE, puede tener una relevante importancia para poder trabajar en su prevención y mejorar la orientación de las intervenciones psicológicas.(AU)

One of the most common sexual dysfunctions is erectile disorder (ED). Therefore, this research aims to identify factors associated with the severity of ED. Thirty-six men, aged 18 to 70 years, with a diagnosis of ED, based on DSM-V criteria, were assessed by means of a clinical interview and a battery of 7 questionnaires (IIEF, SCL-90, PDQ-4, PSWQ, STAI, SSES, SSEI). The methodology focused on a quantitative, descriptive-correlational study of ex post facto design with convenience sampling. The results of the final regression model shows that sexual self-efficacy, certain personality tendencies and the symptomatology of depression, somatization, obsession-compulsion and anxiety are factors associated with the severity of TE, explaining 51.3% of the variance. Being able to identify those factors associated with the severity of TE may be of relevant importance in order to work on its prevention and improve the orientation of psychological interventions.(AU)

Reflexiones sobre la aplicación de la "Ley Trans” en la atención sanitaria / Reflections on the application of the “trans law” in health care

En este artículo se reflexiona sobre la reciente ley aprobada por el Congreso de los Diputados conocida como Ley 4/2023 para la igualdad real y efectiva de las personas trans y para la garantía de los derechos de las personas LGTBI (BOE-A-2023-5366, 2023). Se analizan inicialmente los artículos que más polémica han causado en el ámbito social, que son los relativos a la rectificación registral (Art. 43-51), y posteriormente los que hacen referencia directa o indirectamente a aspectos sanitarios; 1) el que prohíbe de métodos, programas o las llamadas terapias de conversión (Art. 17), 2) los que definen cómo debe ser en términos generales la atención sanitaria (Art. 56-59), y 3) finalmente el único artículo que menciona a los menores (Art 70). Se comenta que el término utilizado de persona trans, al englobar un amplio abanico de diversidades sexuales, variantes y expresiones de género, incluye tanto a personas que necesitan una atención médica como a otras que no. Se plantea que la rectificación registral acorde con esta ley 2023 al no precisar ningún requisito para su inscripción, ofrece menos garantías que la legislación ya existente de marzo 2007. Se considera que las directrices de la nueva ley se están traduciendo en una toma de decisiones por parte del usuario sin disponer de una valoración o diagnóstico por el equipo de profesionales que atienden el caso. Se destaca que la ley no incluye ninguna referencia a la atención por salud mental. Y en conjunto, se concluye que el texto aprobado, en el ámbito sanitario, puede mermar la calidad de la asistencia integral, sobre todo en menores, o personas con identidades complejas, dudosas, o con comorbilidades, que pueden generar discrepancia entre el criterio del profesional y la opinión del usuario.(AU)

Cross-sectional anatomy, computed tomography and magnetic resonance imaging of the head of common dolphin (Delphinus delphis) and striped dolphin (Stenella coeruleoalba).

Computed tomography (CT) and low-field magnetic resonance imaging (MRI) were used to scan seven by-caught dolphin cadavers, belonging to two species: four common dolphins (Delphinus delphis) and three striped dolphins (Stenella coeruleoalba). CT and MRI were obtained with the animals in ventral recumbency. After the imaging procedures, six dolphins were frozen at -20°C and sliced in the same position they were examined. Not only CT and MRI scans, but also cross sections of the heads were obtained in three body planes: transverse (slices of 1 cm thickness) in three dolphins, sagittal (5 cm thickness) in two dolphins and dorsal (5 cm thickness) in two dolphins. Relevant anatomical structures were identified and labelled on each cross section, obtaining a comprehensive bi-dimensional topographical anatomy guide of the main features of the common and the striped dolphin head. Furthermore, the anatomical cross sections were compared with their corresponding CT and MRI images, allowing an imaging identification of most of the anatomical features. CT scans produced an excellent definition of the bony and air-filled structures, while MRI allowed us to successfully identify most of the soft tissue structures in the dolphin's head. This paper provides a detailed anatomical description of the head structures of common and striped dolphins and compares anatomical cross sections with CT and MRI scans, becoming a reference guide for the interpretation of imaging studies.

Sex addiction and gambling disorder: similarities and differences.

OBJECTIVE: Recently, the DSM-5 has developed a new diagnostic category named "Substance-related and Addictive Disorders". This category includes gambling disorder (GD) as the sole behavioral addiction, but does not include sex addiction (SA). The aim of this study is to investigate whether SA should be classified more closely to other behavioral addictions, via a comparison of the personality characteristics and comorbid psychopathology of individuals with SA with those of individuals with GD, which comes under the category of addiction and related disorders. METHOD: The sample included 59 patients diagnosed with SA, who were compared to 2190 individuals diagnosed with GD and to 93 healthy controls. Assessment measures included the Diagnostic Questionnaire for Pathological Gambling, the South Oaks Gambling Screen, the Symptom CheckList-90 Items-Revised and the Temperament and Character Inventory-Revised. RESULTS: No statistically significant differences were found between the two clinical groups, except for socio-economic status. Although statistically significant differences were found between both clinical groups and controls for all scales on the SCL-90, no differences were found between the two clinical groups. The results were different for personality characteristics: logistic regression models showed that sex addictive behavior was predicted by a higher education level and by lower scores for TCI-R novelty-seeking, harm avoidance, persistence and self-transcendence. Being employed and lower scores in cooperativeness also tended to predict the presence of sex addiction. CONCLUSIONS: While SA and GD share some psychopathological and personality traits that are not present in healthy controls, there are also some diagnostic-specific characteristics that differentiate between the two clinical groups. These findings may help to increase our knowledge of phenotypes existing in behavioral addictions.

Cross-sectional anatomy, computed tomography and magnetic resonance imaging of the thoracic region of common dolphin (Delphinus delphis) and striped dolphin (Stenella coeruleoalba).

The aim of this study was to provide a detailed anatomical description of the thoracic region features in normal common (Delphinus delphis) and striped dolphins (Stenella coeruleoalba) and to compare anatomical cross-sections with computed tomography (CT) and magnetic resonance imaging (MRI) scans. CT and MRI were used to scan 7 very fresh by-caught dolphin cadavers: four common and three striped dolphins. Diagnostic images were obtained from dolphins in ventral recumbency, and after the examinations, six dolphins were frozen (-20°C) and sliced in the same position. As well as CT and MRI scans, cross-sections were obtained in the three body planes: transverse (slices of 1 cm thickness), sagittal (5 cm thickness) and dorsal (5 cm thickness). Relevant anatomical features of the thoracic region were identified and labelled on each section, obtaining a complete bi-dimensional atlas. Furthermore, we compared CT and MRI scans with anatomical cross-sections, and results provided a complete reference guide for the interpretation of imaging studies of common and striped dolphin's thoracic structures.

Naso-pharyngeal mites Halarachne halichoeri (Allman, 1847) in Grey seals stranded on the NW Spanish Atlantic Coast.

In North Atlantic European waters, the nasal mite Halarachne halichoeri has been described affecting Grey seals (Halichoerus grypus) producing different levels of respiratory disease. This study provides data on the prevalence, clinical signs and produced macro-pathology of this parasite mite infecting juvenile wild Grey seals stranded in North-Western Spanish coast. Among the 25 seals examined during the study, a total of 19 had nasal mites in their respiratory upper ways, including adult and larval stages. This represented a percentage of prevalence of 76 ± 8.37. All the live positive seals presented a typical clinical symptomatology associated to upper respiratory tract infections. In dead positive seals, a light to intense sinusitis could be diagnosed macroscopically. The presence of the parasite in the nasal sinuses appears as the primary cause of the high respiratory tract symptomatology presented in most of the juvenile seals stranded in the north coast of Spain. Ultrastructural characterization by scanning electronic microscopy (SEM) has confirmed the taxonomic status of the mite. This identification of H. halichoeri represents the first description of the occurrence of this parasite in Southern Europe.

Bioaccumulation of persistent organic pollutants in female common dolphins (Delphinus delphis) and harbour porpoises (Phocoena phocoena) from western European seas: geographical trends, causal factors and effects on reproduction and mortality.

Concentrations of polychlorinated biphenyls (PCBs) in blubber of female common dolphins and harbour porpoises from the Atlantic coast of Europe were frequently above the threshold at which effects on reproduction could be expected, in 40% and 47% of cases respectively. This rose to 74% for porpoises from the southern North Sea. PCB concentrations were also high in southern North Sea fish. The average pregnancy rate recorded in porpoises (42%) in the study area was lower than in the western Atlantic but that in common dolphins (25%) was similar to that of the western Atlantic population. Porpoises that died from disease or parasitic infection had higher concentrations of persistent organic pollutants (POPs) than animals dying from other causes. Few of the common dolphins sampled had died from disease or parasitic infection. POP profiles in common dolphin blubber were related to individual feeding history while those in porpoises were more strongly related to condition.

Spanish perspective on enlarging a small specialty: the national research network for liaison psychiatry and psychosomatics.

The Spanish Research Network in Liaison Psychiatry and Psychosomatics (REPEP) comprises 11 centers (nodes), and was one of the successful applicants in a very competitive call for a networking program for the National Institute of Health "Carlos III" project. This article describes its general objectives and strategic plans. Both qualitative and quantitative results support our statement that this "perspective" should help to enlarge what is presently a small specialty. Synergies in the network have been potentiated; an ambitious national study on depressive comorbidity in complex medical patients has been executed; and new research and training programs have been initiated.

Specific aspects of erectile dysfunction in psychiatry.

The participation of the psychiatrist in the management of erectile dysfunction (ED) is focused on three types of patients based on the origin of the dysfunction: (1) patients with functional or psychogenic ED, (2) patients with mixed, organic psychogenic ED, and (3) patients with ED and active psychopathology. The second group is influenced by three psychological factors: perpetuating factors, aggravating factors, and accompanying factors. The main psychopathological disorders that interfere directly with the erectile mechanism are depressive disorders (18-35%), anxiety disorders (37%), obsessive-compulsive disorder, psychotic disorders (46-47%), and the antipsychotic medications used to treat these disorders. The diagnostic proposal includes psychological and sexologic evaluation and differential diagnosis. The therapeutic proposal includes the basic principles of sex therapy in the model of behavioral-cognitive therapy (eg, prohibition of intercourse, sensate focus, voluntary loss of erections, no expectations about response), pharmacological therapy (eg, sildenafil, intracavernous injection of vasoactive drugs), and a combination of both therapies.

[Multinational European project and multicenter Spanish study of quality improvement of assistance on consultation-liaison psychiatry in general hospital: clinical profile in Spain]. / El proyecto multinacional europeo y multicéntrico español de mejora de calidad asistencial en psiquiatría de enlace en el hospital general: el perfil clínico en España.

BACKGROUND: In the frame of the European study on quality assurance in consultation liaison psychiatry and psychosomatics (supported by the BIOMED 1 program), the clinical <> of consultation-liaison psychiatry units pertaining to six Spanish general hospitals is analyzed. PATIENTS AND METHOD: A sample of 3. 608 consecutive patients referred to the consultation-liaison psychiatry units of five public general hospitals (Clínico of Zaragoza, Clínico of Barcelona, General of Alicante, Ramón y Cajal of Madrid, Princesa of Madrid) and one private gynecological hospital (Dexeus of Barcelona) was studied. The data were recorded with a standardized instrument (CL-BDoK-P), validated in a previous study. RESULTS: Consult request took place 10.6 days (on average) after the patients admission (<>), half the requests were urgent, and psychiatric consultants examined the patients 1.9 days (on average) after the request (<>). The most frequent reasons for referral were current psychiatric symptoms (50.3%), unexplained physical symptoms (15.2%), substance abuse (9.2%), psychiatric history (8.5%), suicide risk (6%) and coping with illness (5.8%). The main referral services were internal medicine (17.5%), traumatology (7.5%) and general surgery (7.3%). An important clinical activity is documented in patients frequently considered to be <>, with broad spectrum diagnostic and interventions processes and both in-hospital and out-patient follow-up. However, some problems were also detected in the clinical <>. CONCLUSIONS: The results outline the clinical importance of Spanish consultation-liaison psychiatry in the general hospital, but the possibility of improving its efficiency through the implementation of integrative models, organizational changes and modern models of <> is also emphasized.

[Subtyping panic disorders according to their symptoms]. / Subtipificación de los trastornos de pánico en función de sus síntomas.

BACKGROUND: Panic disorder (PD) is a common illness associated with high levels of disability and with a high utilisation of non-psychiatric health services which is inefficient in most cases. A better understanding of the clinical subtyping of PD may improve diagnosis both in psychiatric and medical settings. The present study is aimed at assessing the frequency, factorial grouping and comorbidity of PD symptoms in a naturalistic sample of patients. PATIENTS AND METHODS: All consecutive cases of PD (n = 442) who contacted with two outpatient clinics in Barcelona (Spain) were assessed by two experienced interviewers. Assessment instrument included SCID-UP-R interview and inventory of panic symptoms based on DSM-III-R. RESULTS: Palpitations (86.7%), shortness of breath (76.5%), fear of dying (69.9%) and dizziness (63.6%) were the most frequent and intense symptoms reported by the PD patients. The principal component analysis revealed four factors which explained the 56% of the variancel "cardiorespiratory" (23.2%), "depersonalization-derealization" (15.8%), "vestibular" (10%) and "mixed" (7%). CONCLUSIONS: The frequency of presentation of symptoms was similar to other studies. However some disimilarities appeared that may be attributed to transcultural differences as well as terminological problems and the range of symptoms assessed. Factors found in the present study support the clinical subtyping of PD in 3 groups characterised by cardiorespiratory symptoms and fear of dying, cognitive symptoms (depersonalization-derealization) and vestibular symptoms such as dizziness and faintness.

Semiology and subtyping of panic disorders.

To date, the quantitative psychopathology of panic disorder (PD) has been less well studied than that of other psychiatric conditions such as schizophrenia or major depression. The aim of the present study was to assess the frequency and factorial grouping of symptoms in a naturalistic sample of PD patients. A total of 274 consecutive cases of PD who contacted an out-patient clinic in Barcelona, Spain were assessed by two experienced interviewers. The assessment instruments included the Structured Clinical Interview for DSM-III-R Upjohn version (SCID-UP-R) and an inventory of panic attack symptoms based on DSM-III-R. Of the patients who presented at the unit during the assessment period, 8.5% presented with PD. Palpitations, shortness of breath, fear of dying and dizziness were the most frequent and intense symptoms reported by the PD patients. Principal-component analysis revealed four factors which accounted for 57% of the variance, including 'cardiorespiratory' (26.1%) and 'vestibular' (15.1%) factors, and two additional factors with mixed symptoms. The frequency of presentation of symptoms was similar to that reported in other studies. However, some discrepancies were observed that may be attributed to transcultural differences as well as to terminological problems and the range of symptoms assessed. These factors may also explain some of the differences found in factor analysis groupings in previous studies. Our findings support the symptom subtyping of PD.
