Diagnosis, assessment and management of delusional jealousy in Parkinson’s disease with and without dementia

Patients with Parkinson’s disease (PD) may present delusional jealousy (DJ). In a previous cross-sectional prevalence study we identified 15 cognitively preserved and five demented PD patients with DJ. The current study aimed at evaluating their clinical (motor and non-motor) characteristics and the pharmacological treatments associated with DJ, and its subsequent pharmacological management. Patients were assessed by neurologists and psychiatrists using the Hoehn and Yahr scale, the Unified Parkinson’s Disease Rating Scale, the Brief Psychiatric Rating Scale, the Beck Depression Inventory, the Hamilton Anxiety Scale and the Neuropsychiatric Inventory. Efficacy of DJ management was evaluated in follow-up visits. All patients were in therapy with dopamine agonists. A subgroup of five cognitively preserved patients developed DJ after a short period of treatment of therapy with dopamine agonists, while other patients developed DJ after a longer period of dopaminergic treatment. Psychiatric comorbidities were common in cognitively preserved and in demented patients. The pharmacological management included the interruption of dopamine agonists in two patients and the reduction of dopamine agonist dose plus the use of antipsychotics in other patients. These clinical data suggest that the management of medicated PD patients should include investigation for the presence of DJ and the evaluation of clinical characteristics potentially relevant to the prevention or the early recognition of delusions.     

Current practice of chronic hepatitis B treatment in Southern Italy

BackgroundTreatment choice for chronic HBV infection is a continuously evolving issue, with a wide range of options. We aimed to evaluate the current practice of HBV therapies in the real world in Southern Italy.MethodsA prospective study enrolling over a six month period (February–July 2010) all consecutive HBsAg positive subjects, never previously treated, referred to 16 liver units in two Southern Italy regions (Calabria and Sicily).ResultsOut of 247 subjects evaluated, 116 (46.9%) had HBV-DNA undetectable or lower than 2000 UI/ml. There were 108 (43.7%) inactive carriers, 103 (41.7%) chronic hepatitis, and 36 (14.6%) liver cirrhosis. Antiviral treatment was planned in 94 (38.0%) patients (26 cases with Interferon or Pegylated Interferon and 68 with nucleos(t)ides analogues). As many as 49.5% of subjects with chronic hepatitis did not receive antiviral treatment.DiscussionThe majority of chronic HBsAg carrier referring centres for evaluation were not considered suitable for antiviral treatment. Nucleos(t)ides analogues are the preferred first choice for therapy. A long-lasting period of observation may be needed to make appropriate therapeutic decisions in several cases.     

Axial deformation during coronary stenting: an extreme case

We describe a case of longitudinal stent compression induced by withdrawal of a "buddy wire," which we managed by crushing the retracted struts using another stent. To the best of our knowledge, this is one of the first reports of this complication induced by wire manipulation.     

Polycythemia as rare secondary direct manifestation of acromegaly: management and single-centre epidemiological data

Polycythemia associated with acromegaly is usually caused by the systemic manifestations of the disease, such as sleep-apnea or concomitant erythropoietin-secreting kidney tumors. The recognition of underlying pathologies requires a thorough diagnostic process. We report a unique case of acromegaly with polycythemia, not caused by commonly described manifestations of the disease, and receding with octreotide therapy. The medical history of 141 acromegalic patients followed by the Endocrinology Unit of the San Martino University Hospital in Genoa has been also reviewed, together with the literature evidence for similar cases. The diagnostic workflow and 2-years follow-up of a 43-years old acromegalic, polycythemic man with a history of past smoking, moderate hypertension, and mental retardation are described. The hematological parameters of our cohort was retrospectively compared with those of a healthy, age/gender-related control group as well. Therapy with octreotide LAR, 20?mg i.m. q28d was begun soon after diagnosis of acromegaly in the polycythemic patient. Haematocrit level, hormonal setting, as well as pituitary tumor size and visual perimetry during treatment were recorded. Octreotide LAR treatment normalized hormonal alterations, as well as hematological parameters. Polycythemia has not recurred after 2?years of therapy. The median hemoglobin and hematocrit levels of the retrospectively analyzed cohort of acromegalic were significantly lower than normal ranges of a healthy, age/sex- related control population. In conclusions, polycythemia can be a direct, albeit rare, secondary manifestation of acromegaly, that must be considered during the diagnostic work-up of acromegalic patients presenting with such disorder.
