ABSTRACT
This focused review presents a critical appraisal of the World Heart Federation criteria for the echocardiographic diagnosis of rheumatic heart disease (RHD) and its performance in African RHD screening programmes. It identifies various logistical and methodological problems that negatively influence the current guideline's performance. The authors explore novel RHD screening methodology that could address some of these shortcomings and if proven to be of merit, would require a paradigm shift in the approach to the echocardiographic diagnosis of subclinical RHD.
ABSTRACT
PURPOSE: To try to prove in patients with refractory symptomatic epilepsy due to early brain injury involving thalamus and complicated by CSWS the effects of the isolation of the injured hemisphere, performed with functional hemisperectomy, on epilepsy, namely on CSWS. METHODS: Full clinical follow-up before and after surgery of two cases with CSWS onset at four years in whom functional hemispherecomy was performed with resection of inter-hemispheric connections. RESULTS: An immediate effectiveness of the surgical treatment was observed on both epileptic evolution (no more seizures) and EEG abnormalities. In particular, CSWS completely disappeared, together with a concurrent progressive improving of the cognitive and behavioural disorders. DISCUSSION: The isolation of the injured hemisphere through the section of inter-hemispheric cortico-cortical connections could prevent the contralateral diffusion of discharges coming from the injured cortex and cortico-thalamic network, favouring a normal function of thalamo-cortico-thalamic circuitries in the healthy hemisphere. That could explain the disappearance of CSWS after surgery in our patients and the consequent improvement of cognitive abilities and behaviour.

BACKGROUND: Delay in the diagnosis of intraabdominal pathology is a major contributor to the morbidity and mortality of intensive care unit (ICU) patients. Laparoscopy is a valuable diagnostic tool that can be used safely and efficiently in the evaluation of intraabdominal processes that may be difficult to diagnose with conventional methods. Our goal was to show that laparoscopy performed at the bedside in the ICU could be used as a routine diagnostic tool in the evaluation of critically ill patients, just as computed tomography (CT), ultrasonography (US), and radiography are. METHODS: We present 11 patients who underwent 12 bedside examinations in the ICU of a community teaching hospital. Several different surgeons with varying degrees of laparoscopic experience performed these procedures over a 1-year period. RESULTS: Four patients had previously undergone recent abdominal operations. Nontherapeutic laparotomy was avoided in six patients because of diagnostic laparoscopy. One patient also underwent a therapeutic maneuver at the time of diagnostic laparoscopy. None of the patients required general anesthesia, although local anesthetics and sedation with midazolam or propofol were used. One patient underwent the procedure without endotracheal intubation. There were no complications or mortalities directly related to the procedure. CONCLUSION: We conclude that bedside laparoscopy in the ICU under local anesthesia is a diagnostic and potentially therapeutic tool that can be used safely in the work-up of potential abdominal pathology in critically ill patients.
