Culture, Gender, and Aggression in Psychodynamic Group Therapy: A Case of a Male-Only Group with Female Leaders in Iran.

The article focuses on a male-only therapy group that has been functioning for the last nine years in the Middle East, in Iran. The group has a permanent main female therapist and temporary, mostly female trainee cotherapists. We explore culturally specific factors that we believe impact expressions of aggression in the group. These factors include the Iranian gender segregation culture, the ideal of masculinity relating to the concept of "Gheirat" (moral vigilance), the legal acceptance of multiple wives in Iran (which often leads to family instability), and the cultural belief about the uncontrollability of sexual desires in men. We also comment on the role of a common dynamic in Iranian families, in which the relationships between mothers and sons are usually overwhelming while the emotional relationships between parents are somehow restrained. We close by discussing future directions for this area of study as well as by proposing interventions therapists may consider when encountering related group dynamics.

Radiofrequency ablation with four electrodes as a building block for matrix radiofrequency ablation: Ex vivo liver experiments and finite element method modelling. Influence of electric and activation mode on coagulation size and geometry.

PURPOSE: Radiofrequency ablation (RFA) is increasingly being used to treat unresectable liver tumors. Complete ablation of the tumor and a safety margin is necessary to prevent local recurrence. With current electrodes, size and shape of the ablation zone are highly variable leading to unsatisfactory local recurrence rates, especially for tumors >3 cm. In order to improve predictability, we recently developed a system with four simple electrodes with complete ablation in between the electrodes. This rather small but reliable ablation zone is considered as a building block for matrix radiofrequency ablation (MRFA). In the current study we explored the influence of the electric mode (monopolar or bipolar) and the activation mode (consecutive, simultaneous or switching) on the size and geometry of the ablation zone. MATERIALS AND METHODS: The four electrode system was applied in ex vivo bovine liver. The electric and the activation mode were changed one by one, using constant power of 50 W in all experiments. Size and geometry of the ablation zone were measured. Finite element method (FEM) modelling of the experiment was performed. RESULTS: In ex vivo liver, a complete and predictable coagulation zone of a 3 × 2 × 2 cm block was obtained most efficiently in the bipolar simultaneous mode due to the combination of the higher heating efficacy of the bipolar mode and the lower impedance by the simultaneous activation of four electrodes, as supported by the FEM simulation. CONCLUSIONS: In ex vivo liver, the four electrode system used in a bipolar simultaneous mode offers the best perspectives as building block for MRFA. These results should be confirmed by in vivo experiments.

Refractory thyroid carcinoma: which systemic treatment to use?

The incidence of thyroid cancer has increased markedly in recent decades, but has been stable in terms of mortality rates. For the most part, these cancers are treated with surgery, which may or may not be followed by radioactive iodine depending on the tumor subtype. Still, many of these cancers will recur and may be treated with radioactive iodine or another surgery. It is unclear what treatment is best for cases of locally advanced or metastatic thyroid cancer that are refractory to radioactive iodine. Chemotherapy has a very low response rate. However, in the past few years, several systemic therapies, primarily targeted, have emerged to improve the overall survival of these patients. Alternative treatments are also of interest, namely peptide receptor radionuclide therapy or immunotherapy.

Painful thyroid nodule, a misleading presentation of subacute thyroiditis.

Typical presentation of subacute thyroiditis (SAT) is an anterior neck pain radiating up to the jaw and ear, often associated with asthenia and fever. Biology shows hyperthyroidism and inflammation. The thyroid uptake is low at scintigraphy. However, the clinical presentation of SAT may be misleading. We report two cases of SAT whose initial manifestation was a painful thyroid nodule suspected of malignancy. In both cases, ultrasound feature was a heterogeneous, hypoechoic, ill-defined area with a low vascularization on colour Doppler. These areas were interpreted by radiologist as nodules. Surgery was then considered. Such a presentation should be known by clinicians to prevent unnecessary surgery.

Post-Chernobyl incidence of papillary thyroid cancer among Belgian children less than 15 years of age in April 1986: a 30-year surgical experience.

OBJECTIVE: We raised the question of a possible relationship in Belgium between the occurrence of papillary thyroid carcinoma (PTC) and age of children (<15 years) at the time of the Chernobyl nuclear plant accident in April 1986. SETTING: Referral university centre for endocrine surgery. MATERIAL AND METHODS: Thirty-year prospective study of the experience of a surgical team with PTC since the Chernobyl accident, taken out of 2349 patients operated on for any thyroid lesions from April 1986 to April 2015, comparing the incidence of PTC by age groups. MAIN OUTCOME MEASUREMENT: Comparison of PTC incidence in patients >15 years (group A) and children <15 years (group B) in April 1986. RESULTS: Out of a total of 2349 patients having undergone thyroid surgery for all types of lesions during 30 year after Chernobyl and born before April 1986, 2164 were >15 years of age at the time of the nuclear accident (group A) and 175 developed PTC (8.1%) compared to 36 PTC (19.5%) that occurred in 185 children <15 years of age (group B) in April 1986 (p < 0.001). CONCLUSIONS: Radiation exposure affected residents of countries (including Belgium) well beyond Ukraine and Belarus. This was demonstrated by a 1990 meteorological report. Over 30 years, there has been a persistent higher incidence of PTC among Belgian children below the age of 15 years at the time of the Chernobyl accident. This relationship with age has even been strengthened by the implementation of more sophisticated immunohistochemical biomarkers diagnostic technology since April 2011.

Bipolar radiofrequency ablation with 2 × 2 electrodes as a building block for matrix radiofrequency ablation: Ex vivo liver experiments and finite element method modelling.

PURPOSE: Size and geometry of the ablation zone obtained by currently available radiofrequency (RF) electrodes is highly variable. Reliability might be improved by matrix radiofrequency ablation (MRFA), in which the whole tumour volume is contained within a cage of x × y parallel electrodes. The aim of this study was to optimise the smallest building block for matrix radiofrequency ablation: a recently developed bipolar 2 × 2 electrode system. MATERIALS AND METHODS: In ex vivo bovine liver, the parameters of the experimental set-up were changed one by one. In a second step, a finite element method (FEM) modelling of the experiment was performed to better understand the experimental findings. RESULTS: The optimal power to obtain complete ablation in the shortest time was 50-60 W. Performing an ablation until impedance rise was superior to ablation for a fixed duration. Increasing electrode diameter improved completeness of ablation due to lower temperature along the electrodes. A chessboard pattern of electrode polarity was inferior to a row pattern due to an electric field void in between the electrodes. Variability of ablation size was limited. The FEM correctly simulated and explained the findings in ex vivo liver. CONCLUSIONS: These experiments and FEM modelling allowed a better insight in the factors influencing the ablation zone in a bipolar 2 × 2 electrode RF system. With optimal parameters, complete ablation was obtained quickly and with limited variability. This knowledge will be useful to build a larger system with x × y electrodes for MRFA.

Bipolar radiofrequency ablation with four electrodes: ex vivo liver experiments and finite element method analysis. Influence of inter-electrode distance on coagulation size and geometry.

PURPOSE: The aim of this study was to develop an electrode system with simple needle electrodes which would allow a reliable and predictable ablation zone with radiofrequency ablation (RFA). MATERIALS AND METHODS: In the first step, four parallel electrodes (active length 3 cm, diameter 1.8 mm) were inserted in ex vivo bovine liver. A power of 50 W was applied between two pairs of electrodes for 10 min or until current shut-off due to impedance rise. In the second step, the influence of changing inter-electrode distance on coagulation size and geometry was measured. In the third step, a finite element method (FEM) analysis of the experiment was performed to better understand the experimental findings. RESULTS: A bipolar four-electrode system with templates adjusting the inter-electrode distance was successfully developed for ex vivo experiments. A complete and reliable coagulation zone of a 3 × 2 × 2-cm block was obtained most efficiently with an inter-electrode distance of 2 cm in 5.12 ± 0.71 min. Above 2 cm, coagulation was incomplete due to a too low electric field, as demonstrated by the FEM analysis. CONCLUSIONS: The optimal inter-electrode distance of the present bipolar four-electrode system was 2 cm, allowing a reliable and predictable ablation zone in ex vivo liver. The FEM analysis correctly simulated and explained the findings in ex vivo liver. The experimental set-up may serve as a platform to gain more insight and to optimise the application of RFA by means of four or more simple needle electrodes.

[Assimilation of problematic experiences: a case study on short-term dynamic psychotherapy]. / Assimilation des expériences problématiques: une étude de cas de psychothérapie psychodynamique limitée dans le temps.

The assimilation model is a qualitative and integrative approach that enables to study change processes that occur in psychotherapy. According to Stiles, this model conceives the individual's personality as constituent of different voices; the concept of voice is used to describe traces left by past experiences. During the psychotherapy, we can observe the progressive integration of the problematic voices into the patient's personality. We applied the assimilation model to a 34-session-long case of an effective short-term dynamic psychotherapy. We've chosen eight sessions we transcribed and analyzed by establishing points of contact between the case and the theory. The results are presented and discussed in terms of the evolution of the main voices in the patient.

Change in defense mechanisms and coping over the course of short-term dynamic psychotherapy for adjustment disorder.

Short-term dynamic psychotherapy (STDP) has rarely been investigated with regard to its underlying mechanisms of change, even if psychoanalytic theory informs us about several potential putative mechanisms of change in patients. Change in overall defensive functioning is one. In this study, we explored the role of overall defensive functioning, by comparing it on the process level with the neighbouring concept of overall coping functioning. A total of N=32 patients, mainly presenting adjustment disorder, were included in the study. The patients underwent STDP up to 40 sessions; three sessions per psychotherapy were transcribed and analyzed by using two observer-rating scales: Defense Mechanism Rating Scales (Perry, 1990) and Coping Action Patterns (Perry, Drapeau, Dunkley, & Blake, 2005). Hierarchical linear modeling was applied to model the change over the course of therapy and relate it to outcome. Results suggest that STDP has an effect on the target variable of overall defensive functioning, which was absent for overall coping functioning. Links with outcome confirm the importance of the effect. These results are discussed from methodological and clinical viewpoints.

[Being the sibling of a child suffering from cancer: a support group]. / Etre le frère ou la soeur d'un enfan atteint d'un cancer: un groupe de parole.

This paper offers a reflection on the family life and that of the siblings of a child with cancer. We will present our intervention model developed jointly by the pediatric oncology and the pediatric psychiatry units at the University Hospital CHUV in Lausanne. It is known that siblings show difficulties in dealing with the ambivalent emotions triggered by the sickness of a brother or sister. Their defence mechanisms can be heavy and may have consequences on the child's psycho-affective development and on the dynamics of the whole family. Speech groups allow the siblings to unfold an experience which is often irrepresentable. They also permit remobilization of affects frozen by the illness. This model used since 2006 in our unit responds to the wish to improve the quality of care of heavily sick children.

Alliance patterns over the course of short-term dynamic psychotherapy: the shape of productive relationships.

The shape of alliance processes over the course of psychotherapy has already been studied in several process-outcome studies on very brief psychotherapy. The present study applies the shape-of-change methodology to short-term dynamic psychotherapies and complements this method with hierarchical linear modeling. A total of 50 psychotherapies of up to 40 sessions were included. Alliance was measured at the end of each session. The results indicate that a linear progression model is most adequate. Three main patterns were found: stable, linear, and quadratic growth. The linear growth pattern, along with the slope parameter, was related to treatment outcome. This study sheds additional light on alliance process research, underscores the importance of linear alliance progression for outcome, and also fosters a better understanding of its limitations.

Early change in defence mechanisms and coping in short-term dynamic psychotherapy: relations with symptoms and alliance.

Several patient-related variables have already been investigated as predictors of change in psychodynamic psychotherapy. Defensive functioning is one of them. However, few studies have investigated adaptational processes, encompassing defence mechanisms and coping, from an integrative or comparative viewpoint. This study includes 32 patients, mainly diagnosed with adjustment disorder and undergoing time-limited psychodynamic psychotherapy lasting up to 40 sessions, and will focus on early change in defence and coping. Observer-rater methodology was applied to the transcripts of two sessions of the first part of the psychotherapeutic process. It is assumed that the contextual-relational variable of therapeutic alliance intervenes as moderator on change in adaptational processes. Results corroborated the hypothesis, but only for coping, whereas for defences, overall functioning remained stable over the first 20 sessions of psychotherapy. These results are discussed within the framework of disentangling processes underlying adaptation, i.e., related to issues on trait and state aspects, as well as the role of the therapeutic alliance.
