Duodenal diverticulum as a cystis neoplasm of pancreas Objective: The duodenal diverticulum presents with a frequency of 1 to 23% according to radiological series and autopsies. The most frequent localization is the second duodenal portion near the pancreatic head so it may be confused with cystic pancreatic neoplasms. Material and Method: We present a patient with diagnosis of radiological suspicion by means of echoendoscopy and fine needle aspiration biopsy (FNAB) of a mucinous neoplasm of the pancreas that was intervened, being a hardening of the pancreatic head and a duodenal juxtavaterian diverticulum, being performed a block removal on suspicion of malignancy. Result: The patient's postoperative period was favorable and the anatomopathological result of the pancreatic tissue was of pancreatic tissue without anomalies and duodenal diverticulum. Discussion: The preoperative differential diagnosis of duodenal diverticulum with mucinous cystic neoplasia of the pancreas is very complex, since the puncture of the fluid inside the diverticulum may be similar to that of a neoplastic process of the pancreatic mucin. Before the suspected diagnosis and the presence of clinic is indicated to perform exploratory laparotomy, to obtain a diagnosis of certainty.

According to an epidemiological study conducted in France [1], the prevalence of symptomatic knee arthritis is estimated as 7.6%, which in relation to the French population aged between 40 and 75 years (INED 2008 data) corresponds to a total population of about 2 million patients. To evaluate everyday disability (in the broad sense of the term) due to knee arthritis in a population whose diagnosis has recently been confirmed. Methods: The disability generated was evaluated by means of the BONe'S questionnaire. The BONe'S (Burden Osteoarthritis New Scale) questionnaire has been recently validated. It consists of 20 items, structured around 5 dimensions: "Autonomy", "Relationships and leisure", "Hygiene and beauty", "Psychology" and "Budget". Prospective, non-interventional evaluation. 100 French doctors (rheumatologists and general practitioners) recruited patients who had consulted them spontaneously and for whom knee arthritis was diagnosed. Results: 456 subjects were deemed eligible for evaluation. The sex ratio favoured women (65% against 35%). The average age of the population was 65.16 AE 10.9 years. 35% declared that they were active. The average BMI of the population was 27.75 AE 4.9; the proportions for men and women were respectively: 27% and 34% < 25, 46% and 34% between 25 and 30, 21% and 32% > 30. The mean score of the burden was found to be 30.04 AE 17.8. The score differed according to sex: 31.33 AE 16.9 against 28.34 AE 18.9 (p < 0.05). The score also differed according to BMI: 26.1 AE 17.4 if <25, 30.8 AE 18.1 between 25 and 30 and 33.6 AE 17 if >30 (p < 0.01). The most affected dimensions were autonomy, leisure and psychology. The effect on the budget dimension was 6 times greater for active patients compared to inactive patients. The monthly expenses to be paid by the patient differed depending on the sex: V31.09 for women and V23 for men (not significant). Conclusions: This evaluation confirms the impact of knee arthritis in the everyday life of subjects who suffer from it. 35% of subjects are active, and the negative impact on work is liable to grow in view of the ageing of the population and the longer working lives in developed countries.
