A case of disintegrated Strattice™ 4 years after immediate breast reconstruction.

Acellular dermal matrices (ADMs) are used frequently in immediate breast reconstruction (IBR). In general, the porcine-derived ADM Strattice™ has been reported with good outcomes and low complication rates. Nonetheless, we report here a case of a 42-year-old, otherwise healthy woman with a history of uncomplicated bilateral prophylactic nipple-sparing mastectomies and subpectoral IBRs performed using Strattice™ and Mentor® CPG™, who was referred to the Department of Plastic Surgery 4 years after this surgery due to changed appearance of her breast implants. Both CPG implants were found intact and there were no signs of infection but, surprisingly, the Strattice™ had completely disintegrated on both sides. Examinations did not show any malignancies, and at 1-year clinical follow-up, the patient had no signs of relapse. Thus, we suggest that the Strattice™ had disintegrated as a late aseptic foreign body reaction and emphasise the importance of surgeons being aware of this late and rare complication.

Information processing and attentional dysfunctions as vulnerability indicators in schizophrenia spectrum disorders.

The schizotypal personality disorder is believed to be part of the schizophrenic spectrum of disorders including schizophrenic patients as well as some of their seemingly unaffected relatives with discreet symptoms. Spectrum-individuals are characterised by a genetic vulnerability for schizophrenia. The vulnerability is connected with neurocognitive deficits independent of clinical state. Some cognitive dysfunctions are unspecific and probably related to non-genetic brain damage. A consistent finding has, however, been poor performance in tasks involving information processing and attention. The findings point to the existence of specific sensory-perceptual deficits or a general attentional dysfunction. Identification of cognitive disturbances characteristic not only of schizophrenics, but also of schizotypal disordered and their relatives in the boundaries of schizophrenia, is relevant in order better to understand the pathogenetic mechanisms and treatment of schizophrenia. In the present review clinical data are analysed based on models of vulnerability and information processing with reference to a characterisation of the neuro-integrative deficits that form the core abnormalities of the spectrum.
