Risk of complications after core needle biopsy in pheochromocytoma/paraganglioma

Core needle biopsy (CNB) has been used with caution in pheochromocytoma and paraganglioma (PPGL) due to concerns about catecholamine-related complications. While it is unclear what scientific evidence supports this claim, it has limited the acquisition of biological samples for diagnostic purposes and research, especially in metastatic PPGL. We performed a systematic review and individual patient meta-analysis to evaluate the risk of complications after CNB in PPGL patients. The primary and secondary objectives were to investigate the risk of death and the occurrence of complications requiring intervention or hospitalization, respectively. Fifty-six articles describing 86 PPGL patients undergoing CNB were included. Of the patients (24/71), 34% had metastases and 53.4% (31/58) had catecholamine-related symptoms before CNB. Of the patients (14/41), 34.1% had catecholamine excess testing prior to the biopsy. No CNB-related deaths were reported. Four patients (14.8%, 4/27) experienced CNB-related complications requiring hospitalization or intervention. One case had a temporary duodenal obstruction caused by hematoma, two cases had myocardial infarction, and one case had Takotsubo cardiomyopathy. Eight patients (32%, 8/25) had CNB-related catecholamine symptoms, mainly transient hypertension, excessive diaphoresis, tachycardia, or hypertensive crisis. The scientific literature does not allow us to make any firm conclusion on the safety of CNB in PPGL. However, it is reasonable to argue that CNB could be conducted after thorough consideration, preparation, and with close follow-up for PPGL patients with a strong clinical indication for such investigation

Criminal narrative experience: relating emotions to offence narrative roles during crime commission

A neglected area of research within criminality has been that of the experience of the offence for the offender. The present study investigates the emotions and narrative roles that are experienced by an offender while committing a broad range of crimes and proposes a model of Criminal Narrative Experience (CNE). Hypotheses were derived from the Circumplex of Emotions (Russell, 1997), Frye (1957), Narrative Theory (McAdams, 1988) and its link with Investigative Psychology (Canter, 1994). The analysis was based on 120 cases. Convicted for a variety of crimes, incarcerated criminals were interviewed and the data were subjected to Smallest Space Analysis (SSA). Four themes of Criminal Narrative Experience (CNE) were identified: Elated Hero, Calm Professional, Distressed Revenger and Depressed Victim in line with the recent theoretical framework posited for Narrative Offence Roles (Youngs & Canter, 2012). The theoretical implications for understanding crime on the basis of the Criminal Narrative Experience (CNE) as well as practical implications are discussed

Genetic Alterations and Molecular Signatures in Aldosterone Producing Adenomas

Primary Aldosteronism (PA) is caused by autonomous overproduction of aldosterone. Aldosterone is necessary for fluid and ion homeostasis. Aberrant overproduction leads to hypertension and cardiovascular damage. With a prevalence of over 5% in the worlds’ hypertensive community, and with over a billion people worldwide having high blood pressure, PA represents a major contributor to health care costs and morbidity. Importantly, 30% of PA patients have a unilateral dominant secretion, an aldosterone producing adenoma (APA), making it possible to cure a substantial portion of patients with surgery. Unfortunately, there is a large underdiagnosis of PA, leading to delayed diagnosis in many patients, worsening their outcome after surgery. A need for better screening techniques, raised awareness and treatment options for PA is warranted. Since 2011, the genetic understanding of APAs has revolutionized. Somatic mutations turning on an autonomous aldosterone production has been observed in up to 80% of tumors. In this thesis we have investigated the genetic landscape and phenotypes of APAs. By international collaborations we have collected one of the largest cohorts of APAs ever sequenced. We have confirmed and extended the understanding of KCNJ5 mutations, its associated phenotype and the specificity for APAs. We have confirmed a high rate of mutations in ATP1A1, ATP2B3 and CACNA1D, and noted distinct clinical and molecular phenotypes in these tumors. We describe a marker of Zona Glomerulosa cells, perhaps important for the normal regulation and function of these cells. We observe somatic mutations in CTNNB1, occurring in a mutually exclusive manner to the other mutations. Using in situ sequencing, we note genetic heterogeneity in APAs with KCNJ5 mutations. Finally, we evaluate intratumoral aldosterone measurement on a large cohort of tumors, validating a high specificity for APAs. Noting also a difference in the level of intratumoral aldosterone between APAs and a possible association with genotype. Remarkably, we also note a robust correlation between the intracellular concentrations and plasma-aldosterone. We hope that with gained knowledge of the genetic background, the understanding of both pathologic and normal states of the adrenals will increase, and hopefully benefit patients in the future
