[Hemorrhagic shock revealing multiple digestive microaneurysms in a patient with systemic lupus erythematosus: Case report and literature review]

INTRODUCTION

The vascular disorders in systemic lupus erythematosus (SLE) result from various mechanisms and presentations (inflammatory disease or vasculitis, atherosclerosis).

CASE REPORT

We report on a 34-year-old man with cutaneous, articular, neurological and nephrologic SLE. He presented with catastrophic haemorrhage on microaneurysm rupture of the left hepatic artery. After blood transfusions and immunosuppressive treatments, his condition improves.

CONCLUSION

Uncommon complication in SLE patients, digestive vasculitis with microaneurysms may occur as in polyarteritis nodosa. In the literature, we identified 10 additional cases of hepatic microaneurysms in SLE patients. The main issue is an earlier diagnosis in order to give appropriate treatment and improve prognosis.

State of sport in South Africa: Questions that need answers

Playing time between senior rugby players of different ethnic groups across all levels of South African rugby, 2007- 2011

Background. The South African Rugby Union (SARU) has had a continual challenge to make the game representative of players of all ethnic groups at all levels of play. In response to this challenge SARU has implemented several programmes designed to accelerate the development of players from previously disadvantaged areas with the goal of making the game more representative. However, the success of these programmes to transform the player profile at different levels of rugby cannot be evaluated because the players representing different ethnic groups have not been quantified in a systematic way.Objectives. To quantify the number and playing time of South African professional players (Vodacom, Currie Cup, Super Rugby and Springboks) from different ethnic groups from 2007 to 2011 to determine whether there are any changes in the profile of the players over this period.Methods. Playing time was recorded for all players in sanctioned matches. Players were divided into the ethnic classifications used by SARU (i.e. white, coloured and black).Results. At all levels of competition there were proportionally more white players, followed by coloured players and then black players. This pattern did not change from 2007 to 2011. Based on the ratio of number of players v. playing time, the white players played more time than expected at the Springbok level, whereas the black players played less than expected for the number of players from 2007 to 2011. At the Vodacom level the white players played more than expected in 2007 and 2008 and played less than expected in 2010 and 2011, whereas the black players played more than expected in 2010 and the coloured players played more than expected at the 2011 tournament. The Super Rugby tournamenthad the most consistency between players and expected playing time for the different ethnic groups.Conclusions. Despite the effort to support players from disadvantaged backgrounds since 1998 with facilitative programmes and selection targets, the professional game is still dominated by white players at all levels.

The relationships between rugby players' tackle training attitudes and behaviour and their match tackle attitudes and behaviour

Background

The tackle event in rugby is a technical and physical contest between opposing players. A player's ability to tolerate and contest during a tackle is a prerequisite for safe participation and success in rugby. Little is known about the relationship between tackle training and tackling in matches in rugby union. Therefore, we investigated the relationships between players’ training attitudes and behaviour and their match attitudes and behaviour for tackling in rugby union.

Method

A questionnaire was designed to assess attitude (importance) and behaviours (frequency and quantity) among junior (under 19) players on a 5-point Likert Scale. Questionnaires were handed out to 220 players (10 schools) at a tournament and 75% (9 schools, n=164) were returned for analysis. Associations between training attitudes and behaviours were tested using the χ² test, Cramer's V and τ-b.

Results

The more time spent on emphasising proper technique to prevent injuries in training, the more important players rated ‘own safety’ (τ-b=0.21, moderate, z=3.1, p<0.01), ‘going for the ball only’ (τ-b=0.27, moderate, z=4.6, p<0.001) and ‘staying on feet’ (τ-b=0.23, moderate, z=3.6, p<0.001) in match play. The more time spent on emphasising proper technique to improve performance in training, the more important players rated actions ‘going for ball only’ (τ-b=0.23, moderate, z=3.7, p<0.001) and ‘preventing the ball carrier from retaining position’ (τ-b=0.20, moderate, z=3.1, p<0.01) in match play.

Conclusions

This is the first study to report on the relationships between players’ training attitudes and behaviour and their match attitudes and behaviours for tackling in rugby union. The importance of tackle training to prevent injury, and the amount of time spent on technique to prevent injuries, was associated with behaviours that reduce the risk of injury in matches.

Unilateral adrenal hemorrhagic infarction in essential thrombocythemia

Adrenal hemorrhage is a rare disease associated with various conditions. We report a case of a 68-year-old woman with abdominal and back pain. The diagnostic work-up showed a left adrenal gland infarction associated with essential thrombocythemia. Treatment consisted in painkillers and treating the underlying condition in order to prevent further thrombotic events.
