Autism spectrum disorder, very-early onset schizophrenia, and child disintegrative disorder: the challenge of diagnosis. A case-report study.

Background: Autism spectrum disorder (ASD) in the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5) contains several disorders previously present as distinct diagnoses in the DSM Revised Fourth Edition (DSM-IV-TR). These include child disintegrative disorder (CDD). The latter presents typical features, such as a late regression of developmental acquisitions. However, it also shows symptoms similar to ASD, and psychotic symptoms, such as very-early onset schizophrenia (VEOS), are described in the literature. Case report: In this case report we deepen the case of P., a child who presents a late regression, at 7 years old, associated with psychotic symptoms in the absence of organic alterations. The child was treated with antipsychotic drug therapy and cognitive behavioral therapy. P. was diagnosed with ASD with acute and late regression associated with psychotic symptoms. During the follow-up, there was a gradual improvement in the clinical conditions. Improvements were possible due to therapeutic intervention (pharmacological and psychotherapeutic) and/or the natural course of the disorder. Conclusion: The diagnostic difficulty of this case reflects a clinical complexity in which it is not easy to distinguish between neurodevelopmental and psychiatric aspects. Clinical cases such as that of P. emphasize the theme of the neurodevelopment continuum model in which neurodevelopmental and psychiatric disturbances can be considered within a pattern of pathological continuity.

Serial quantitative angiographic study of target lumen enlargement after drug-coated balloon angioplasty for native coronary artery disease.

BACKGROUND: Target lumen enlargement (TLE) or "late lumen enlargement" is often encountered after percutaneous coronary intervention (PCI) with drug-coated balloons (DCB). To date, the prognosis of coronary arterial lesions with or without TLE has not been clearly elucidated. AIMS: This study aimed to assess the long-term prognosis of coronary arterial lesions with or without TLE observed within 1 year (early TLE) after DCB angioplasty using serial quantitative angiographic follow-up. METHODS: One hundred and ninety-three consecutive patients (de novo coronary arterial lesions, 251) who underwent follow-up angiography within 1 year after DCB angioplasty (early follow-up, median: 6 months) were retrospectively evaluated. Of these, 97 patients (125 lesions) also underwent angiography more than 1 year after DCB angioplasty (late follow-up, median: 37 months). TLE was defined as an increase in minimal lumen diameter (MLD) after PCI at each follow-up. RESULTS: Early TLE was detected in 142 lesions (56.6%). Of these, 76 lesions were also evaluated at late follow-up. TLE persisted even at late follow-up in 67 of the 76 lesions (88.2%). An increase in MLD in early TLE (+) lesions was observed in the period between post-PCI and early follow-up (1.84 ± 0.06 vs. 2.12 ± 0.07 mm, p < 0.001) but not between early and late follow-up (2.12 ± 0.07 vs. 2.16 ± 0.07 mm, p = 0.74). In contrast, 49 of 109 lesions without early TLE were evaluated at late follow-up, of which 28 lesions (57.1%) showed TLE at late follow-up. The MLD of early TLE (-) lesions (n = 49) significantly increased from early (1.63 ± 0.061 mm) to late follow-up (1.84 ± 0.06 mm) (p < 0.001). No aneurysms were found in any of these cases. CONCLUSION: Early TLE was observed in more than half of the lesions, with the majority remaining at late follow-up. Alternatively, half of the lesions without early TLE showed late TLE, occurring biphasically after DCB angioplasty.

Catatonia: A Common Cause of Late Regression in Autism.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by social communication deficits and restricted interests and behaviors which begin very early in life. In about a quarter of cases, the symptoms emerge about 18-24 months after a period of normal development, a phenomenon commonly described as early regression. However, marked functional decline can also occur in persons with autism after a relatively stable childhood. As opposed to early regression, which occurs in normally developing children, late regression occurs typically in adolescents with an established diagnosis of autism. Apart from their occasional mention in the literature, these individuals have not been examined systematically. This Brief Report describes the presentation, comorbidity and short-term outcome of 20 persons with ASD who developed late regression. The mean age of onset of regression was 13 years. One of the earliest symptoms was an increase in obsessive slowing and compulsive rituals. Other symptoms included motor abnormalities, aggression and mood disturbance. The most common comorbid disorder was catatonia occurring in 17 patients. Despite treatment with several modalities, the outcome was often suboptimal. These findings suggest that catatonia is a common cause of late regression in persons with autism. Clinical and research implications are discussed.
