The abnormal animal featured here is a frog with extra legs. It grew the extra legs because it was infected with a parasite when it was a tadpole, and the parasite caused the growing leg to split into pieces. A similar thing happens in a fly that also has extra legs, except that there there's no parasite, just necrosis.
Levamisole is an increasingly common cutting agent used with cocaine. Both cocaine and levamisole can have local and systemic effects on patients.
Methods
A retrospective case series was conducted of patients with a cocaine-induced midline destructive lesion or levamisole-induced vasculitis, who presented to a Dundee hospital or the practice of a single surgeon in Paisley, from April 2016 to April 2019. A literature review on the topic was also carried out.
Results
Nine patients from the two centres were identified. One patient appeared to have levamisole-induced vasculitis, with raised proteinase 3, perinuclear antineutrophil cytoplasmic antibodies positivity and arthralgia which improved on systemic steroids. The other eight patients had features of a cocaine-induced midline destructive lesion.
Conclusion
As the use of cocaine increases, ENT surgeons will see more of the complications associated with it. This paper highlights some of the diagnostic issues and proposes a management strategy as a guide to this complex patient group. Often, multidisciplinary management is needed.
A large variety of techniques have been used for auricular haematoma management. The open surgical management of auricular haematoma involves incision, evacuation and the obliteration of dead space using biodegradable mattress sutures. Our goal was to describe open surgical management for primary, recurrent and spontaneous auricular haematoma.
Methods:
Auricular haematoma patients who underwent open surgical management were prospectively audited (2010–2013). Information was collected on demographics, clinical presentation, aetiology, examination findings, previous interventions, details of open surgical management and post-operative follow up.
Results:
In all, 12 male and 3 female patients with a mean age of 33 years (range 16–86 years) were evaluated. Contact sport injury was the most common aetiology. Ten patients had undergone previous unsuccessful interventions to treat auricular haematoma before open surgical management was performed. All patients were managed successfully without significant recurrence. One patient had a minor local reaccumulation which required reinsertion of a mattress suture. One elderly patient developed localised cellulitis which responded well to antibiotics.
Conclusion:
Open surgical management of auricular haematoma has been successful. The technique is simple and reliable, and can be accomplished in a clinical setting under local anaesthesia.
We report the first record of an elasmobranch (shark) with cyclopia and other abnormalities (albinism, absence of nostrils, a bump on the snout and a slight abnormality in the vertebral column). These malformations were found in an embryonic dusky shark Carcharhinus obscurus caught near Cerralvo Island in the Gulf of California, Mexico. Tomographic images were taken to observe these deformities in detail. The causes of these deformities are uncertain but may be attributed to congenital malformation during embryonic development (holoprosencephaly).
Cerebral palsy (CP) may be categorized into its clinical subtypes (spastic quadriplegia, diplegia, hemiplegia; dyskinetic or ataxic forms, and mixed), by severity. It may be further grouped according to whether or not etiology is considered known through neuroimaging, chromosomal, metabolic, or other evidence. The hypothesis that birth asphyxia is a major cause of CP has not led to the development of therapies producing a net decrease in CP. Known risk factors for CP in very low birthweight (VLBW) infants differ somewhat from those in term babies. The diagnosis of CP rests on identification of abnormalities of tone, reflexes, and posture, as assessed after the first year of life and preferably not before age 3 years; earlier diagnostic assessments are unstable, especially in children born prematurely. The goals of intervention in CP are to improve function, prevent deformities and discomfort, and make care easier.
