Febrile Ulceronecrotic Mucha-habermann Disease: a Rare, Severe Variant

JOURNAL OF CUTANEOUS PATHOLOGY, Issue 1 2006
Michele M. Thompson
A 56 year old Hispanic man presented with extensive ulcerative skin lesions, involving his lower trunk, groin and upper legs, severe pain and a temperature of 38.7 degrees Celsius. He was admitted to the Medical Intensive Care Unit for empiric intravenous antibiotics. Several biopsies were performed. In the following days his condition worsened and ulcerative lesions involved nearly all of his skin. Previous biopsies were consistent with pityriasis lichenoides et varioliformis acuta (PLEVA), however, neither this, nor others in the histological differential diagnosis, fit his severe and worsening clinical picture. Histology revealed vacuolar alteration with dyskeratotic keratinocytes and a superficial perivascular mixed infiltrate of lymphocytes and eosinophils. There was confluent parakeratosis containing neutrophils, and a diminished granular layer with pallor in the upper portion of the spinous layer. Immunofluorescence studies were negative. These findings were consistent with PLEVA. A clinical diagnosis of febrile ulceronecrotic Mucha-Habermann disease was made. Febrile ulceronecrotic Mucha-Habermann disease is a rare and severe variant of PLEVA characterised by high fever and papulonecrotic skin lesions. Twenty-five cases have been previously reported. We present the clinical and histological findings in this unusual clinical presentation. [source]

How does premenstrual dysphoric disorder relate to depression and anxiety disorders?

DEPRESSION AND ANXIETY, Issue 3 2003
Mikael Landén M.D., Ph.D.
Abstract Premenstrual dysphoric disorder (PMDD) is a severe variant of premenstrual syndrome that afflicts approximately 5% of all women of fertile age. The hallmark of this condition is the surfacing of symptoms during the luteal phase of the menstrual cycle, and the disappearance of symptoms shortly after the onset of menstruation. Whereas many researchers have emphasized the similarities between PMDD and anxiety disorders, and in particular panic disorder, others have suggested that PMDD should be regarded as a variant of depression. Supporting both these notions, the treatment of choice for PMDD, the serotonin reuptake inhibitors (SRIs), is also first line of treatment for depression and for most anxiety disorders. In this review, the relationship between PMDD on the one hand, and anxiety and depression on the other, is being discussed. Our conclusion is that PMDD is neither a variant of depression nor an anxiety disorder, but a distinct diagnostic entity, with irritability and affect lability rather than depressed mood or anxiety as most characteristic features. The clinical profile of SRIs when used for PMDD, including a short onset of action, suggests that this effect is mediated by other serotonergic synapses than the antidepressant and anti-anxiety effects of these drugs. Although we hence suggest that PMDD should be regarded as a distinct entity, it should be emphasized that this disorder does display intriguing similarities with other conditions, and in particular with panic disorder, which should be the subject of further studies. Also, the possibility that there are subtypes of PMDD more closely related to depression, or anxiety disorders, than the most common form of the syndrome, should not be excluded.

Unipolar depression with racing thoughts: A bipolar spectrum disorder?

PSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 5 2005
FRANCO BENAZZI md
Abstract Major depressive disorder (MDD) with racing/crowded thoughts is understudied. Kraepelin classified ,depression with flight of ideas' in the mixed states of his manic-depressive insanity. The aim of the study was to test whether MDD with racing/crowded thoughts was close to bipolar disorders. Consecutive 379 bipolar-II disorder (BP-II) and 271 MDD depressed outpatients were interviewed using the Structured Clinical Interview for DSM-IV, the Hypomania Interview Guide, and the Family History Screen, by a senior psychiatrist in a private practice. Intra-depression hypomanic symptoms were systematically assessed. Mixed depression was defined as a major depressive episode (MDE) plus three or more intra-MDE hypomanic symptoms. MDD with racing/crowded thoughts was compared to MDD without racing/crowded thoughts on classic bipolar validators (young onset age, many recurrences, atypical and mixed depression, bipolar family history). Frequency of MDD with racing/crowded thoughts was 56.4%. MDD with racing/crowded thoughts, versus MDD without racing/crowded thoughts, had significantly lower age at onset, more MDE severity, more psychotic, melancholic, atypical, and mixed depressions, and more bipolar family history. Of the intra-MDE hypomanic symptoms, irritability, psychomotor agitation and distractibility were significantly more common in MDD with racing/crowded thoughts. Compared to BP-II on bipolar validators, validators were less common in MDD with racing/crowded thoughts. MDD with racing/crowded thoughts seemed to be a severe variant of MDD. MDD with racing/crowded thoughts versus MDD without racing/crowded thoughts, and versus BP-II, had significant differences on bipolar validators, suggesting that it may lie along a continuum linking MDD without racing/crowded thoughts and BP-II.
