Superficial vein thrombosis: risk factors,diagnosis, and treatment

Superficial vein thrombosis (SVT) risk factors are close to those of venous thromboembolism (VTE). Diagnosis is made in a clinical setting but ultrasonography is useful to eliminate concomitant deep vein thrombosis (DVT). For SVT of the lower limbs, which is the main location, varicose veins represent the principal cause but underlying conditions (e.g.: autoimmune diseases, malignancy or thrombophilia) must be sought in idiopathic, migrant or recurrent SVT and in the absence of varicose veins. Concomitant DVT and pulmonary embolism can occur in approximately 15% and 5% respectively. Historical treatments consist of anti-inflammatory agents plus elastic stockings and, in case of varicose veins, thrombectomy and stripping. Other treatments (anticoagulants, vein ligation) were assessed to limit the VTE risk. A one-month prophylactic dose of low molecular weight heparin plus elastic stockings could be the appropriate strategy in most cases. Other studies are needed before definitive conclusions can be drawn.     

Considération critique sur l’extension de la bipolarité, psychopathologie des mouvements d’humeur et de l’euphorie morbide

Objectives

From manic-depressive psychosis to bipolar spectrum, today's psychiatry allows us to observe a widening of bipolar criteria. This article aims at studying this evolution, its consequences with a critical look and the psychopathology of mood changes and morbid euphoria.

Methods

All of our considerations refer to current data on bipolar disorders (review with Medline and Science Direct) compared with studies from classical psychiatrists (Kraepelin, Ey) and various authors inspired by psychoanalysis (Freud, Racamier) and phenomenology (Binswanger, Tellenbach, Tatossian).

Results

Many contemporary authors encourage clinicians to detect bipolar disorders from symptoms, early signs and attenuated or atypical expressions. The concept of a widened spectrum is supposed to be closer to clinical reality and it would be an opportunity to diagnose this disease and its deleterious consequences better and thus to set up an appropriate therapy at an early stage. Other authors, on the other hand, deplore a dilution of bipolar disorders together with harmful diagnostic inflation around a concept that has become too heterogeneous to be effective, that subjugates or interferes with other pathologic entities in an excessive manner and abandoning a psychopathological approach. In this view, we shall analyze the nosographic shifts of bipolar disorders throughout the history of psychiatry, from manic-depressive psychosis to bipolar disorder and spectrum. We shall then scrutinize the autonomy and limitations related to bipolar disorders as opposed to normality, confusing clinical presentations and other major mental diseases: Psychosis, depression, pathological personality, anxiety, impulse-control, attention deficit-hyperactivity, addiction and psycho-organic disorders. This work shall first introduce a discussion on the concept of bipolar disorders for children, and then through the case of some historical figures. Then we will deal with the contemporary social factors that are currently furthering the extension of this diagnosis. Last, this article sheds a light on psychopathological specificities of mania – the cornerstone in bipolar disorders – mood changes and morbid euphoria.

Conclusion

We think that classic psychiatry, phenomenology and psychoanalysis would act as a guiding light through this debate and could help the clinician in this daily practice. Mood variations require a careful clinical observation and a rigorous set of interpretation, before being specified too excessively or hastily as a symptom of a real bipolarity.     

Molecular characterization of Ancylostoma braziliense larvae in a patient with hookworm-related cutaneous larva migrans

We report a case of hookworm-related cutaneous larva migrans diagnosed microscopically. Viable hookworm larvae were found by microscopic examination of a skin scraping from follicular lesions. Amplification and sequencing of the internal transcribed spacer 2 allowed the specific identification of the larvae as Ancylostoma braziliense.
