Approximately one third of depressed outpatients present with "anger attacks", sudden spells of anger accompanied by symptoms of autonomic activation such as tachycardia, sweating, flushing, and tightness of the chest. These anger attacks are experienced by the patients as uncharacteristic of them and inappropriate to the situations in which they occur. Depressed patients with anger attacks are significantly more anxious and hostile, and they are more likely to meet criteria for borderline, histrionic, narcissistic, and antisocial personality disorders than depressed patients without anger attacks. Treatment studies suggest that antidepressant treatment of anger attacks in depression is helpful and sage. Anger attacks disappear in 53-71% of depressed outpatients treated with antidepressants such as fluoxetine (Prozac), sertraline and imipramine. In addition, the rate of emergence of anger attacks after treatment with fluoxetine (Prozac) (6-7%) is no different from the rates observed after treatment with sertraline (8%) and imipramine (10%), and lower than the rate with placebo (20%). Finally, one can hypothesize that antidepressants that affect serotonergic neurotransmission, known to be involved in the modulation of aggressive behavior in animals and humans, should be particularly effective in this population. Larger placebo-controlled studies, comparing selective serotonin reuptake inhibitors such as fluoxetine with relatively noradrenergic tricyclic antidepressants such as desipramine, may help us understand whether depressed patients with anger attacks show a distinctive responsiveness to drug treatment.

A number of phenomenologic studies have demonstrated the marked heterogeneity of unipolar depressive disorders. We have recently identified a subtype of depression characterized by the presence of irritability and anger attacks. These attacks are sudden spells of anger accompanied by symptoms of autonomic activation such as tachycardia, sweating, flushing, and tightness of the chest. They are experienced by depressed patients as uncharacteristic of them and inappropriate to the situations in which they occur. Approximately one third of depressed outpatients present with anger attacks. Patients with unipolar depression and anger attacks frequently experience significant anxiety and somatic symptoms, and are relatively more likely to meet criteria for avoidant, dependent, borderline, narcissistic, and antisocial personality disorders than depressed patients without these attacks. Anger attacks subside in 53% to 71% of depressed outpatients treated with antidepressants, and the degree of improvement in depressive symptoms after antidepressant treatment is comparable in depressed patients with and without anger attacks. In addition, the rate of emergence of anger attacks after treatment with antidepressants (6%-10%) appears to be lower than the rate with placebo (20%). Finally, antidepressants that affect serotonergic neurotransmission, known to be involved in the modulation of aggressive behavior in animals and humans, may be particularly effective in this subtype of depression, but further studies are needed to support this hypothesis.

The prevalence of behaviour problems is reported from a questionnaire study among members of the Danish Kennel Club (DKC). In total, 4359 dog owners were included in the analyses. With logistic regression, we analysed four behaviour problems: dominance towards the owner, interdog dominance aggression, separation anxiety and shooting phobia. Compared to Labrador Retrievers, the following breeds and breed groups had higher odds of being reported to have interdog dominance aggression: Belgian Sheepdogs, Dachshunds, Dalmatians, German Shepherds, Hovawarts, Pinschers, Rottweilers, Scent dogs and Spitz dogs. Poodles, retrieving/flushing dogs, Sheepdogs, Spitz dogs and terriers had higher odds of shooting phobia. The odds of interdog dominance aggression were higher among dogs owned by younger dog owners compared to dogs owned by older dog owners. Dogs living in the capital area of Copenhagen had increased odds of interdog dominance aggression as compared to dogs living in other parts of Denmark. Dogs belonging to owners with limited knowledge of the breed before acquiring the dog had higher odds of interdog dominance aggression. Dogs attending obedience training classes had reduced odds of shooting phobia. Dogs belonging to dog breeders had reduced odds of being reported to have the investigated behaviour problems.

Systemic mastocytosis (SM), as opposed to cutaneous-only mastocytosis, implies the presence of neoplastic mast cell infiltration in extracutaneous tissue. Mast cell disease in adults is often systemic and often involves the bone marrow. Typical clinical and laboratory features of SM include urticaria pigmentosa, mast cell mediator symptoms (eg, headache, flushing, lightheadedness, urticaria and pruritus, nausea, diarrhea, abdominal pain, and vasodilatory shock), bone pain (eg, osteoporosis, lytic bone lesions, and fractures), hepatosplenomegaly, cytopenia, eosinophilia, elevated serum tryptase and histamine, and bone marrow fibrosis and angiogenesis. SM may be indolent (no evidence of organ dysfunction), aggressive (presence of organ dysfunction), associated with another often chronic myeloid hematologic disease (SM-AHD), or present as mast cell leukemia or sarcoma. Mast cell-mediator symptoms are treated with histamine antagonists and cromolyn sodium. Indolent SM does not require cytoreductive therapy. Aggressive SM and SM-AHD are managed based on their molecular profile. Recent information suggests that FIP1-like-1-platelet-derived growth factor receptor-alpha(+) SM responds well to imatinib mesylate, whereas interferon-alpha should be considered as a first-line treatment in all of the other cases, including patients with Asp816Val(+) SM. Cladribine has been shown to be effective in patients who develop resistance to interferon treatment.

An oil spill on 2 January 1990 in New Jersey resulted in premature emergence of fiddler crabs Uca pugnax from their underground burrows. Live fiddler crabs that emerged on the surface were collected and behavioral changes were compared between those that were washed with freshwater and those that were not washed. Locomotion, aggression, balance, and burrowing behavior were examined. Unwashed crabs improved significantly on only one of twelve behavioral tests, while washed crabs improved in four tests relating to movement, defensive behavior, and burrowing. The washed crabs showed the greater improvement on ten of twelve tests while unwashed crabs showed greater improvement for two tests. Washed crabs also showed greater improvement in their ability to find and to construct their own burrows. These experiments indicate that oil removal improves the behavioral performance of crabs, and suggests that under some circumstances the immediate flushing of salt marsh creeks by uncontaminated tidal waters may decrease behavioral effects on crabs.

Mastocytosis (MC) encompasses a range of disorders characterized by a clonal, pathological accumulation of mast cells having a somatic activating mutation of the tyrosine kinase receptor Kit (exon 17, codon 816; D816V) in more than 90 % of adult patients. The mutation is much less common in children. Skin and bone marrow are most often affected. Symptoms and clinical course are very heterogeneous due to a variable degree of local or systemic mediator release or organ dysfunction as a result of mast cell infiltrates. Pruritus, wheals, flushing and gastrointestinal symptoms are often reported. The majority of pediatric patients experience spontaneous remission of MC. Adults usually have chronic disease, rarely transforming into an aggressive or lethal type. Indolent systemic MC with involvement of skin and bone is the most common type. In MC the risk for anaphylactic reactions following an insect sting (and other causes of mast cell activation) is increased significantly. Diagnostic hallmarks are biopsies from skin and bone marrow using tryptase antibodies for staining as well as serum tryptase levels. At present a curative treatment for MC is not available. Systemic histamine H(1) receptor antagonists are widely used. Aggressive types of MC respond partially to IFN-alpha or cladribine. A variety of receptor tyrosine kinase inhibitors is still under critical evaluation for systemic treatment of MC. After introduction of the WHO classification for MC and the development a German MC guideline, as well as the foundation of national and international competence networks for MC, a significantly improved quality of medical care for MC patients can be expected for the future.

The scopolamine patch is usually used to reduce postoperative nausea and vomiting associated with anesthesia and/or surgery. It is also commonly used for the prevention of motion sickness. Transdermal scopolamine patches have been used for decades and there are few reports in the literature of toxic psychosis associated with the product. Most documented cases of acute psychosis following administration of scopolamine or other anticholinergic agents have been from the adult population. Here we present a 4-year-old boy with deteriorated cognitive function and changed mental status acutely. Besides flushing skin and psychotic behaviors including bizarre actions, hallucinations, aggressive behavior, hyperactivity, and incoherent speech were also noticed. Symptoms and signs were resolved after removal of scopolamine patch and conservative management. This case is possibly one of the youngest patients to exhibit such toxic effects. We hope to relay information about common agents with anticholinergic effects to clinical practitioners and remind that drug-induced psychosis should be considered in children with acute changes in behavior.

We report two families with Brunner syndrome living in one state of Australia. The first family had a predicted protein-truncating variant of monoamine oxidase A (MAOA) (p.S251KfsX2). Affected males had mild intellectual disability (ID), obsessive behaviour, limited friendships and were introverted and placid during clinical interview. The family disclosed episodic explosive aggression after a diagnosis was made. The second family had a missense variant in MAOA (p.R45W). Affected males had borderline-mild ID, attention deficit disorder and limited friendships. One had a history of explosive aggression in childhood and episodic symptoms of flushing, headaches and diarrhoea. Their carrier mother had normal intelligence but similar episodic symptoms. Characteristic biochemical abnormalities included high serum serotonin and urinary metanephrines and low urinary 5-hydroxyindoleacetic acid (5-HIAA) and vanillylmandelic acid (VMA). Symptomatic individuals in the second family had particularly high serotonin levels, and treatment with a serotonin reuptake inhibitor and dietary modification resulted in reversal of biochemical abnormalities, reduction of 'serotonergic' symptoms and behavioural improvement. Brunner syndrome should be considered as a cause of mild ID with paroxysmal behavioural symptoms. It can be screened for with serum/urine metanephrine and serotonin measurement. Cautious treatment with a serotonin reuptake inhibitor, dietary modifications and avoidance of medications contraindicated in patients on monoamine oxidase inhibitors can improve symptoms.
