A systematic survey of the methods literature on the reporting quality and optimal methods of handling participants with missing outcome data for continuous outcomes in randomized controlled trials.

Objective: To conduct (1) a systematic survey of the reporting quality of simulation studies dealing with how to handle missing participant data (MPD) in randomized control trials and (2) summarize the findings of these studies.

Study Design And Setting: We included simulation studies comparing statistical methods dealing with continuous MPD in randomized controlled trials addressing bias, precision, coverage, accuracy, power, type-I error, and overall ranking. For the reporting of simulation studies, we adapted previously developed criteria for reporting quality and applied them to eligible studies.

Urine TREM-1 as a marker of urinary tract infection in children.

Objective Triggering receptor expressed on myeloid cells (TREM)-1 is a receptor that is thought to improve recognition of patients with true infection. In this study, we investigated whether Triggering receptor expressed on myeloid cells (TREM-1) is present in urine samples from children with urinary tract infection (UTI) and in samples from healthy children. Methods A total of 128 samples met the inclusion criteria for the study.

[Non-traumatic spontaneous retroperitoneal bleeding: the effect of an early and accurate diagnosis].

Background: Spontaneous sub-capsular or peri-renal haemorrhage (Wunderlich syndrome) is a rare condition that involves a diagnostic challenge. In many cases, bleeding leads to haemodynamic instability that may be life threatening. Therefore, it is important to have a high clinical suspicion for timely action.

Update of the Mexican College of Rheumatology guidelines for the pharmacologic treatment of rheumatoid arthritis.

Background: The pharmacologic management of rheumatoid arthritis has progressed substantially over the past years. It is therefore desirable that existing information be periodically updated. There are several published international guidelines for the treatment of rheumatoid arthritis that hardly adapt to the Mexican health system because of its limited healthcare resources.

Clinical features and differential diagnoses of solitary extramedullary plasmacytoma of the thyroid: a case report.

A 40-year-old woman presented with a rapidly enlarging palpable thyroid mass. The patient underwent a total thyroidectomy. The tumor fulfilled the criteria of primary solitary extramedullary plasmacytoma (SEP), including cellular expression of the CD138 and lambda light chain antibodies.

Chirurgica Taurina: a 10-year experience of bullfight injuries.

Background: Despite recent efforts to improve medical treatment for injured bullfighters, including the foundation of a scientific society for bullfight injuries, serious injuries, in particular in villages and smaller arenas, still do occur. We are not aware of any series in the English literature that aimed to study the specific mechanisms, types, and outcomes of these injuries.

Methods: A review of the trauma registry of injured bullfighters who suffered any type of trauma during bullfighting and received emergency therapy by the Surgical Trauma Services between 1994 and 2004 at the Plaza de Toros Nuevo Progreso, Guadalajara, Mexico.
