Facial self-mutilation: an analysis of published cases

OBJECTIVES Facial self-mutilation is rare. It is usually discussed from the psychiatric or psychoanalytic perspectives but has little prominence in general medical literature. Our objective was to describe facial self-mutilation in terms of its comorbidities, and to outline the different types of facial mutilation, as well as the basic approach to the patients with facial self-mutilation. METHODS We undertook a review of all published cases of facial self-mutilation (1960-2011). RESULTS We identified 200 published cases in 123 relevant papers. Four major groups of comorbidities emerged: psychiatric, neurological and hereditary disorders, and a group of patients without identified comorbidities. There were three general patterns of facial self-mutilation: (1) major and definitive mutilation, with the ocular globe as primary target--seen in patients with psychotic disorders; (2) stereotypical mutilation involving the oral cavity and of variable degree of severity, most often seen in patients with hereditary neuropathy or encephalopathy; (3) mild chronic self-mutilation, seen in patients with non-psychotic psychiatric disorders, acquired neurological disorders, and patients without comorbidities. About 20% of patients that mutilated their face also mutilated extra-facial structures. Patients with psychiatric conditions, especially those with psychotic disorders, had significantly higher (p<0.05) rates of permanent facial self-mutilation than others. Most treatment plans were very individually based, but some principles, such as prevention of irreversible loss of function and structure, or development of infection are applicable to all patients with facial self-mutilation. CONCLUSIONS Facial self-mutilation is a potentially severe manifestation of diverse conditions. Several aspects of facial self-mutilation remain to be fully characterised from a clinical perspective.

Sex differences in the excretion of fecal glucocorticoid metabolites in the Syrian hamster

We verified the relevance of measuring fecal glucocorticoid metabolites (FGM) to assess the stress response of the Syrian hamster. Male and female hamsters (n = 10 each) were submitted to an adrenocorticotropic hormone (ACTH) challenge test, whereas animals in the control group received 0.5 mL of sterile isotonic saline solution. All feces voided by each animal were collected at 4 h intervals from 24 h before (baseline) until 48 h after injections. FGM were quantified using an 11-oxoetiocholanolone enzyme immunoassay (EIA). Basal concentrations of FGM were almost four times higher in males than in females. Following ACTH administration, FGM levels started rising from 8 h onwards, reaching peak concentrations 20 or 28 h post injection in males and females, respectively. Despite the much higher absolute concentrations present in males, the relative increase (500%) in response to the ACTH stimulation was similar in both sexes. Sex differences in FGM levels are in accordance with results reported by others regarding the hamster adrenal physiology. The comparison of the adrenocortical response of males and females to an ACTH challenge provided new information about the amplitude and the timing of such a response and the excretion of glucocorticoids in both sexes. We demonstrated for the first time in the Syrian hamster that adrenocortical activity can be monitored in fecal samples in a noninvasive way. Our study provides a humane, practical, and noninvasive alternative to blood removal and therefore a powerful tool for stress-related studies in a species frequently used as an animal model in medical research.

Female genital mutilation in Switzerland: a survey among gynaecologists.

QUESTION UNDER STUDY: To evaluate the situation of Female Genital Mutilation (FGM) in Switzerland. METHODS: Through a questionnaire, Swiss gynaecologists were asked if they have been confronted to FGMs, if they have been asked to perform infibulations and FGMs. The health representatives (Kantonsärzte/médecins cantonaux) were interviewed on FGM activity at the Canton level. Swiss Medical Schools were asked if FGM was included in the pregraduate curriculum, and an estimated prevalence rate for FGMs in Switzerland was gathered. RESULTS: Among Swiss gynaecologists, 20% reported having been confronted with patients presenting with FGM and among them 40% had been asked about reinfibulation. Gynaecologists are occasionally asked about the possibility of performing FGMs in Switzerland. No activity concerning FGM is reported by health authorities in the Cantons. Teaching about FGM is not included in the curriculum of any of the Swiss medical schools. Approximately 6,700 girls at risk and women who have undergone FGM live in Switzerland. CONCLUSION: The extent to which gynaecologists are confronted to women with FGM may justify further action to try to better understand the situation in Switzerland. Improvement of care by better education of health care providers (guidelines) and prevention of new cases by women's education should also be considered.

Profiling of phenols in human fecal water after raspberry supplementation.

The phenolic compositions of fecal water samples from ten free-living human subjects without marked dietary restrictions were monitored before and after intake of raspberry puree (200 g/day, 4 days) using gas chromatography-mass spectrometry. No single phenolic component was increased in all subjects after intake, but a majority of subjects had significant elevations in phenylacetic acid (7/10), 4-hydroxyphenylacetic acid (6/10), 3-hydroxyphenylacetic acid (5/10), 3-phenylpropionic acid and 3-(4-hydroxyphenyl)propionic acid. The levels of 3,4-dihydroxbenzoic acid were elevated in 8/10 subjects, significantly for 6 subjects (p < 0.05), and not significantly reduced in the other 2 subjects. In addition, unlike most other fecal metabolites, the increase was always >2-fold. This metabolite may be representative of the increased colonic dose of cyanidin anthocyanins. The colonic microbiota varied greatly between individuals, and supplementation with raspberries did not produce any statistically significant alterations in the profile of colonic bacteria, nor was a common pattern revealed to account for the interindividual variations observed in the fecal water phenolic profiles.

Ignatian spirituality and the rebuilding of self-esteem

Of all the relationships in my life, one that has been among the most difficult is the relationship with myself; overcoming low self-confidence is an ongoing struggle. One might contend that self-denigration is a form of self-mutilation, and at times it has been a powerfully destructive force in my life. All too often, low self-esteem has limited the opportunities available to me, and has had an impact on the relationships with significant others in my life, including God. It has even been suggested that it has been one of the inordinateattachments from which I have needed liberating (Exx 23). While the problem is now much less severe than it has been, maintaining a functional level of self-esteem requires ongoing effort. In this paper, it is my aim to tell of my own journey into Ignatian prayer, using illustrations from my own journals, and to explain why it has become important in my efforts to preserve a sense of my own value.

Non-nutritive sucking associated with self-mutilating behavior

Although sucking activity has been considered an essential behavior of early childhood to satisfy nutritive and non-nutritive needs, digit and pacifier sucking are deleterious oral habits that may interfere with child development. Furthermore, this clinical picture may be compounded by other concerning habits, such as self-mutilating behavior. This article reports 4-year follow-up of a child in whom non-nutritive sucking was associated with an unusual self-mutilating behavior; namely, the child would pull out her own hair after wrapping it around her finger every time she sucked on the pacifier. This occurred specially at bedtime, while she was watching TV, or when she was somewhat anxious, and remitted and recurred throughout the follow-up period. In an attempt to address this behavior, pacifier use was discontinued and the child’s head was shaved. Ultimately, the case was only solved through combined efforts involving the child, her family, and health professionals. Based on the parents’ reports and clinical examination and follow-up findings, we emphasize the importance of investigating the origin of the problem and considering emotional aspects and its association with other habits in such cases.

Non-selective cutaneous sensory neurectomy as an alternative treatment for auto-mutilation lesion following arthrodesis in three dogs

OBJECTIVE: To describe an alternative method for the treatment of non-responsive self-mutilation injuries in three dogs after carpal/tarsal arthrodesis. STUDY DESIGN: Case series ANIMALS: Two dogs with carpal injury and one dog with tarsal injury treated by arthrodesis METHODS: All dogs developed self-mutilation injuries due to licking and/or chewing of the toes within 21-52 days of surgery. Clinical signs did not resolve within one week after conservative treatment with wound debridement and protective bandages. Following general anaesthesia, a deep horseshoe-shaped skin incision, including the subdermal tissue, was performed proximal to the self-mutilation injury transecting the sensory cutaneous afferent nerves. The skin incision was closed with simple interrupted sutures. RESULTS: All wounds healed without complication. Self-mutilation resolved completely within 24 hours after surgery in all dogs. No recurrence was observed (5 months to 3 years). CONCLUSION: Non-selective cutaneous sensory neurectomy may lead to resolution of self-mutilation following arthrodesis in dogs. CLINICAL RELEVANCE: Failure of conservative treatment in self-mutilation injuries often leads to toe or limb amputation as a last resort. The technique described in this case series is a simple procedure that should be considered prior to amputation. The outcome of this procedure in dogs self-multilating due to neurological or behavioral disturbances unrelated to carpal or tarsal arthrodesis is not known.

Interventions infirmières en regard du phénomène de l’automutilation en milieu pédopsychiatrique : étude qualitative exploratoire

En milieu pédopsychiatrique, les infirmières connaissent bien le phénomène de l’automutilation des adolescentes parce qu’elles sont souvent appelées à intervenir lorsque ce type de situation survient. Cependant, puisqu’elles ont parfois une mauvaise compréhension du phénomène, des perceptions erronées et des attitudes négatives quant à celui-ci, les infirmières deviennent moins aptes à intervenir auprès de cette clientèle. Cette étude a pour objectifs d’explorer le phénomène de l’automutilation auprès des infirmières œuvrant en milieu pédopsychiatrique et de décrire les interventions infirmières privilégiées en cas d’automutilation ainsi que les facteurs du contexte organisationnel susceptible d’avoir une influence sur la façon dont ces interventions sont prodiguées. L’étude privilégie un devis qualitatif de type exploratoire. Plusieurs méthodes de collecte des données ont été sélectionnées pour mener à bien cette étude entre autres des entrevues auprès des participantes et une période d’observation au sein de l’unité où la recherche a eu lieu. L’analyse des verbatim selon les étapes élaborées par Tesch (1990) a permis d’identifier sept catégories d’interventions infirmières : les interventions de relation d’aide, d’accompagnement, d’évaluation, de sécurité, d’enseignement, les interventions en lien avec les émotions et les perceptions de l’automutilation ainsi que les interventions pour éviter la contamination sociale. En ce qui a trait aux facteurs ayant une influence sur ces interventions infirmières, trois catégories sont ressorties des données : la constitution de l’équipe interpersonnelle, la lourdeur des tâches de l’infirmière en pédopsychiatrie ainsi que la culture organisationnelle dans laquelle évoluent les membres de l’équipe soignante. Les résultats qui sont issus de cette étude permettront aux infirmières de mieux comprendre le phénomène de l’automutilation chez les adolescentes. Cette étude suggère également des pistes d’interventions qui pourraient aider les infirmières œuvrant en milieu pédopsychiatrique à mieux intervenir. De plus, cette étude serait susceptible de permettre aux gestionnaires des établissements d’apporter certains ajustements notamment en ce qui a trait à l’organisation du travail et à la formation des infirmières.

Efectividad del tratamiento farmacológico de la agresividad en pacientes con trastorno límite de la personalidad. Revisión sistemática

Introducción: el Trastorno Límite de la Personalidad afecta del 2% al 6% de los adultos en Estados Unidos. Es una condición de alta relevancia dentro de las patologías psiquiátricas debido a características como impulsividad, inestabilidad en las relaciones interpersonales, disregulación en el estado de ánimo y comportamiento agresivo. Esto determina un impacto negativo en la funcionalidad del individuo siendo la agresividad contra sí mismo o contra otras personas uno de sus componentes claves. Métodos: Revisión sistemática de la literatura de artículos de bases de datos y búsqueda manual de revistas relacionadas que aportaran la mejor evidencia con el fin de encontrar estudios que evaluaran, con instrumentos objetivos, los tratamientos farmacológicos disponibles para el manejo de la agresividad en el TLP .Se evaluó calidad metodológica y los estudios se organizaron en tablas de evidencia. Resultados: La búsqueda arrojo 1081 artículos de los cuales se seleccionaron 52 como potenciales y cinco fueron incluidos en esta revisión. Se clasificaron como nivel de evidencia Ib. El topiramato, el aripiprazol, el divalproato y la fluoxetina mostraron mejores resultados que el placebo especialmente en agresividad e impulsividad. El topiramato fue asociado con pérdida de peso. Los medicamentos fueron seguros y bien tolerados. Discusión: Los medicamentos evaluados mostraron ser mejores que placebo. La diversidad en las escalas utilizadas genera complejidad en la interpretación de resultados. Conclusión: La evidencia sugiere que el tratamiento farmacológico es efectivo en síntomas como agresividad e impulsividad comparado con placebo. Deben considerarse estudios que evalúen combinaciones de fármacos y psicoterapia.

Demetrio Aguilera-Malta: Los que se van: inicios y retornos (Dossier: Cuatro narradores del 30, relecturas en su centenario)

La autora revisa los relatos de Aguilera-Malta incluidos en Los que se van. Ellos anticipan los contenidos y rasgos de su narrativa posterior, constituyendo un verdadero «octamerón de las pasiones» humanas. Sentimientos existenciales complejos animan a los personajes: una amistad llevada a sus límites, el autoengaño en relación al objeto amoroso, la autoexpiación de una vieja culpa, un «Don Juan» de las islas, que súbitamente, al encontrar el amor por primera vez, castiga al mal que lo posee mediante la autocastración y la muerte (el mal como algo intrínseco y extrínseco, a la vez). Una estructura compleja, intensidad en la forma, economía de recursos, claro sentido de fabulación: todos estos elementos, presentes en su narrativa posterior, se evidenciaban ya, con precoz maestría, en los cuentos incluidos en Los que se van.

Impact of dietary polydextrose fiber on the human gut metabolome

The aim of the present study was to elucidate the impact of polydextrose PDX an soluble fiber, on the human fecal metabolome by high-resolution nuclear magnetic resonance (NMR) spectroscopy-based metabolomics in a dietary intervention study (n = 12). Principal component analysis (PCA) revealed a strong effect of PDX consumption on the fecal metabolome, which could be mainly ascribed to the presence of undigested fiber and oligosaccharides formed from partial degradation of PDX. Our results demonstrate that NMR-based metabolomics is a useful technique for metabolite profiling of feces and for testing compliance to dietary fiber intake in such trials. In addition, novel associations between PDX and the levels of the fecal metabolites acetate and propionate could be identified. The establishment of a correlation between the fecal metabolome and levels of Bifidobacterium (R2 = 0.66) and Bacteroides (R2 = 0.46) demonstrates the potential of NMR-based metabolomics to elucidate metabolic activity of bacteria in the gut.

Diagnosing borderline personality disorder : examination of how clinical indicators are used by professionals in the health setting

This paper reviews the history of the recognition of borderline personality disorder as a clinical disorder, followed by a review of the contemporary practice of diagnosing borderline personality disorder in psychiatric settings. Many researchers have cautioned against the conflation of difficult patients with the diagnostic category of borderline personality disorder. The current study examines how clinical indicators used to screen for this complex disorder differ across service settings, professions, specialised training and years of clinical experience. A purpose-designed survey was administered to 108 mental and emergency medicine health practitioners across an Australian health service and a New Zealand health service to record the level of significance placed on different clinical indicators in the application of the diagnosis of borderline personality disorder. A heavy reliance was placed on observable behavioural symptoms, such as self-mutilation and impulsive behaviours that are self-damaging, in the screening of borderline personality disorder as a psychiatric diagnosis. Statistically significant differences were found between emergency medical staff and mental health clinicians in their use of diagnostic indicators of borderline personality disorder, χ²(4) = 17.248, p = .002. Implications of these findings for the screening, assessment and diagnosis of patients with borderline personality disorder are discussed.
