In order to assess the major clinical biological and radiological signs of an intra-abdominal abscess following digestive surgery as well as the place of automatic reoperation, this retrospective study analysed 79 patients requiring intensive therapy for such a complication since 1982. Surgery consisted in oesophagectomy (n = 38), hepatectomy or cholecystectomy (n = 12), pancreatic surgery (n = 17) and colectomy (n = 12). A postoperative abdominal abscess was recognized in 75 patients consisting in intrathoracic or intra-abdominal oesophageal fistulas (n = 31), pancreatic abscesses and fistulas (n = 17), peri- or intrahepatic abscesses (n = 11), colonic fistulas (n = 12) and acalculous cholecystitis. With regard to the intensity of symptomatology the patients have been allocated into 2 groups. In group I, including 12 patients, the infectious syndrome occurred early (3 first postoperative days), was severe and associated with positive blood cultures in 60% of cases. The patients were reoperated without previous CT-scanography. Four died postoperatively. In group II, including 67 patients, the symptomatology was more discrete. CT-scanography was highly beneficial, with discovery of an abscess in 90% of cases. In 20 patients, the abscess has been punctured and drained successfully by percutaneous route. In 6 patients with negative CT-scanography, an automatic reoperation resulted in the discovery of an abscess in 2 cases. Five out of 6 of these patients died postoperatively. It is concluded that in case of intraabdominal complication following digestive surgery: a) in case of early and severe symptomatology, a rapid reoperation is mandatory; b) CT-scanography has a high diagnostic value for abscess recognition in patients with discrete and delayed symptomatology; c) nearly one third of the abscesses can be treated successfully by percutaneous drainage; d) the value of automatic reoperations remains unsubstantiated.

Failure to thrive: A proposed diagnostic approach.
Arch Argent Pediatr

Failure to thrive is a general term describing infants who do not reach weight, length, or body mass index expected for their age. It can be related often to malnutrition due to inadequate caloric and protein intake, but also to excessive loss of nutrients, inadequate metabolism, inadequate absorption, or excessive caloric and energy expenditure. It may be either organic or inorganic in origin, and in most cases, does not require investigation through complementary examinations.

Alzheimer's disease is the neurodegenerative disorder responsible for approximately 60% to 70% of all cases of dementia and is expected to affect 152 million by 2050. Recently, anti-amyloid therapies have been developed and approved by the Food and Drug Administration as disease-modifying treatments given as infusions every 2 to 5 weeks for Alzheimer's disease. Although this is an important milestone in mitigating Alzheimer's disease progression, it is critical for emergency medicine clinicians to understand what anti-amyloid therapies are and how they work to recognize, treat, and mitigate their adverse effects.

Background: In patients with mechanical aortic and mitral valves requiring catheter ablation of ventricular tachycardia (VT), a technique for access from the right atrium (RA) to the left ventricle (LV) via puncture of the inferoseptal process of the LV was previously described in a single-center series.
Objectives: This study sought to report the multicenter experience of VT ablation using this novel LV access approach.
Methods: We assembled a multicenter registry of patients with double mechanical valves who underwent VT ablation with RA-to-LV access.
Looped Penrose Drainages of Acute Hand Infections in Vulnerable Populations.

Purpose: Acute hand infections (AHIs) remain a challenge for hand surgeons and represent a condition for which clinical outcomes are considerably affected by social barriers. We previously described the looped Penrose drainage technique, where a drain is sutured to itself in a loop and the outflow tract of egress is maintained, thus obviating the need for large incisions, wound closure, or repeat packing, thereby reducing the follow-up burden. In the face of escalating numbers of socioeconomically vulnerable patients, especially in urban settings, we aimed to characterize the clinical features and outcomes of this technique in an urban population of patients with AHI.

Purpose: This study aimed to evaluate the long-term efficacy of the ligation of the intersphincteric fistula tract (LIFT) procedure in treating high transsphincteric fistulas.
Methods: We conducted a retrospective study to evaluate the success rate of LIFT treatment in 82 patients with high transsphincteric fistulas involving at least 1/3 of the external sphincter. This study was carried out across 2 centers from November 2009 to February 2023.
