Laparoscopic resection of adrenal neuroblastoma without image-defined risk factors: a prospective study on 21 consecutive pediatric patients

Background

Over the last 20 years MIS has progressively gained popularity in children with cancer. We therefore aimed at evaluating the safety of Minimally Invasive Surgery (MIS) resection in a series of children affected by adrenal neuroblastoma (NB) presenting without Image-Defined Risk Factors (IDRFs).

Methods

An Institutional protocol for MIS resection of adrenal NB in pediatric patients without IDRFs has been applied since 2008. Absence of IDRFs represented the main indication for MIS in NB, regardless of tumor size. All pediatric patients who underwent MIS for NB between January 2008 and May 2013 were included. Specific technical considerations, demographic data, and outcome have been recorded.

Results

Twenty-one patients underwent MIS resection for IDRFs-negative adrenal NB. Nine of these patients experienced preoperative downgrading of IDRFs after chemotherapy. Radiological median diameter of the mass was 30 mm (range 10–83 mm). Median operative time was 90 min. Median hospital stay was 4 days. All patients were treated successfully, without serious intraoperative complications. One mild intraoperative hemorrhage occurred and was treated without the need for conversion to open surgery nor blood transfusion was required. No postoperative complications, including port-site or peritoneal metastases were experienced.

Conclusions

This study demonstrated the safety and effectiveness of MIS for the resection of adrenal NB without IDRFs in children. Pediatric surgeons dedicated to oncology should be aware of this alternative approach to open resection.     

Cognitive abilities in siblings of children with autism spectrum disorders

The aim of the present study was to assess the cognitive profiles of children with autistic spectrum disorder and of their healthy siblings (Siblings). With the term cognitive profile, we indicate the relationship extant among the values of verbal and performance subtests of the Wechsler Intelligence Scale. The conducted statistical analyses indicated that, although siblings showed a normal intelligent quotient and did not differ in this aspect from typically developing group, their cognitive profile was amazingly similar to that of their relatives affected by autism. A k-means clustering analysis on the values of single subtests further confirmed this result, showing a clear separation between typically developing children on the one side, and autistics and their siblings on the other. We suggest that the common cognitive profile observed in autistic children and their siblings could represent a marker of liability to autism and, thus, a possible intermediate phenotype of this syndrome.     

Awareness, treatment, and control of hypertension in the elderly in a general practice experience. Study Group on Hypertension in the Elderly

In 3858 ambulatory elderly people (age greater than or equal to 65 years) prevalence of hypertension was 67.8%. The hypertensive status was unknown to both the doctor and the patient in 21.4% of cases. More than 90% of known hypertensives were treated, but hypertension could be considered as controlled in less than 30% of them.     

How general practitioners perceive and grade the cardiovascular risk of their patients.

BACKGROUND: Although risk assessment charts have been proposed to identify patients at high cardiovascular risk, in everyday practice general practitioners (GPs) often use their knowledge of the patients to estimate the risk subjectively. DESIGN: A cross-sectional study aimed to describe how GPs perceive, qualify and grade cardiovascular risk in everyday practice. METHODS: General practitioners had to identify in a random sample of 10% of their contacts the first 20 consecutive patients perceived as being at cardiovascular risk. For each patient essential data were collected on clinical history, physical examination and laboratory tests, for the qualification of risk. At the end of the process GPs subjectively estimated the overall patient's level of risk. General practitioners grading was compared with the risk estimate from a reference chart. RESULTS: Over a mean time of 25 days 3120 patients perceived as being at cardiovascular risk were enrolled. According to the inclusion scheme each GP had contact with more than 200 patients at cardiovascular risk every month. Thirty percent of these patients had atherosclerotic diseases. Up to 72% of patients without any history of atherosclerotic diseases but perceived to be at risk could be classified according to a reference chart as being at moderate to very high risk. Comparing GPs' grading of risk with a chart estimate there was agreement in 42% of the cases. Major determinants of GPs' underestimation of risk were age, sex and smoking habits, while obesity and family history were independently associated with overestimation. CONCLUSIONS: On the basis of their perception GPs properly identify patients at cardiovascular risk in the majority of cases. General practitioners subjective grading of risk level only partially agreed with that given by a chart.
