In children, 1) serum C-reactive protein is increased in acute appendicitis; 2) such increase is related to the severity of the appendiceal inflammation; and 3) although serum C-reactive protein has an adequate diagnostic accuracy, neither individually nor in combination with the leukocyte count is it significantly better than the leukocyte count alone.

Simple closure followed by Helicobacter pylori (Hp) eradication has become the most used procedure in perforated ulcer treatment. However, its efficacy and safety are still to be determined. To assess recurrence and re-perforation rates, and as a secondary objective, to analyze Hp infection rates in perforated ulcer patients and controls, we conducted a prospective study. Ninety-two consecutive patients (ages: 19-96 years) were operated on between 1996 and 2002, and treated by simple closure followed by Hp eradication and NSAID avoidance. The data were prospectively collected in a database. Hp infection was diagnosed in 68 patients (73.9%). Thirty-four patients (37%) consumed nonsteroidal anti-inflammatory drugs (NSAIDs), and 23 (25%) had both Hp infection and NSAID antecedents. The perforation was gastric in 4 cases and pre-pyloric, pyloric or duodenal in 88. There were postoperative complications in 24 patients (26%) and 4 patients died (4.3%). Hp eradication was shown in 46 patients. There was clinical ulcer recurrence in 4 (4.3%); in 3 of them recurrence manifested as re-perforation, all in gastric locations. Overall relapse and re-perforation 1-year crude rates were 6.1% and 4.1%, respectively. Crude rates for non-gastric ulcer recurrence were 0 at 1 year and 2.6% at 2 years and for non-gastric ulcer re-perforation rates were 0 at 1 and 2 years. This therapeutic strategy is associated with a low rate of recurrence and no re-perforations in case of duodenal, pyloric, or pre-pyloric perforated ulcers, but it is not acceptable for perforated gastric ulcers.

The coexistence of a pancreatic papillary cystic tumor with hairy cell leukemia is reported. To the best of our knowledge this association has never been published. A 41-year-old man diagnosed with hairy cell leukemia developed a second malignancy that corresponded to a papillary cystic pancreatic tumor. The patient underwent splenectomy and a tumoral surgical resection, and is currently well at 21 months follow-up. A pathogenetic relationship between the two malignancies was not demonstrated. Hairy cell leukemia has been reported to be associated to a great number of different second malignancies. In contrast, only two papillary cystic tumors of the pancreas have been described associated to a second neoplasm, a papillary thyroid carcinoma and a colonic carcinoma. This unusual benign or low-grade malignant pancreatic tumor more commonly occurs in the tail of the pancreas of young women. We want to stress the unusual presentation of this pancreatic tumor affecting the head of the gland in a male patient as well as its coexistence with a hairy cell leukemia.
