Localized basal meningeal enhancement in tuberculous meningitis
(2006)
Background: Focal basal meningeal enhancement may produce a confusing CT picture in children with suspected tuberculous meningitis (TBM). Objective: To demonstrate the incidence, distribution and appearance of localized ...
Stereotactic proton beam therapy for intracranial arteriovenous malformations
(2005)
Purpose: To investigate hypofractionated stereotactic proton therapy of predominantly large intracranial arteriovenous malformations (AVMs) by analyzing retrospectively the results from a cohort of patients. Methods and ...
Stereotactic proton beam therapy of skull base meningiomas
(2001)
Purpose: To review outcomes for patients with skull base meningiomas treated using the stereotactic proton beam at the National Accelerator Center (NAC), Republic of South Africa. Methods and Materials: Since 1993, 27 ...
Fine-needle aspiration biopsy: A fi rst-line diagnostic procedure in paediatric tuberculosis suspects with peripheral lymphadenopathy?
(2009)
OBJECTIVE: To evaluate the diagnostic yield and time to diagnosis of fi ne-needle aspiration biopsy (FNAB) vs. routine respiratory specimens collected from children with a palpable peripheral lymph node mass and symptoms ...
Management of life-threatening haemoptysis in an area of high tuberculosis incidence
(2009)
BACKGROUND: Emergency admissions with life-threatening haemoptysis in an area of high tuberculosis (TB) incidence at the University of Stellenbosch and Tygerberg Academic Hospital, South Africa. It is unclear if lung ...
The diagnostic utility of adenosine deaminase isoenzymes in tuberculous pleural effusions
(2009)
SETTING: Pleural adenosine deaminase (ADA) levels have been found to be useful in diagnosing tuberculous pleuritis. Elevated ADA levels have been attributed to ADA2 isoenzyme, although no comprehensive studies have evaluated ...
Cytokine production in patients with tuberculous pericarditis
(2002)
SETTING: An academic hospital in the Western Cape, South Africa. OBJECTIVE: To evaluate cytokine production (interferon-gamma [IFN-γ], interleukin-1 [IL-1], interleukin-2 [IL-2], interleukin-6 [IL-6], interleukin-10 [IL-10], ...
Intracytoplasmic sperm injection with testicular spermatozoa in men with azoospermia
(2002)
Purpose: The aim of the study was to gain an insight into the optimal management of the infertile couple with the husband suffering from azoospermia. Methods: One hundred and forty-two intracytoplasmic sperm injection ...
Relationship between Human Sperm Morphology and Acrosomal Function
(2003)
Purpose: In this study, we investigated the relationship between functionality of the acrosome and sperm morphology. Methods: Acrosome reaction (AR) was separately determined in live and dead sperm and in those with normal, ...
Physiological induction of the acrosome reaction in human sperm: Validation of a microassay using minimal volumes of solubilized, homologous zona pellucida
(2000)
Purpose: To develop a method that could accommodate microvolumes of solubilized human zona pellucida (ZP) and sperm for assessing the induction of the acrosome reaction. Methods: A microassay using 1 μl of 2.5, 1.25, 0.6, ...
