Klüver Bucy syndrome, unusual consequence of excessively rapid correction of severe hyponatremia.

INTRODUCTION: Features of Klüver-Bucy syndrome (KBS) include hypersexuality, hyperorality, placidity, visual agnosia, amnesia, hypermetamorphosis, and emotional and nutritional behavior changes. It is a clinical presentation of bitemporal disorders with limbic system abnormalities. The most common cause of KBS is herpes encephalitis. CASE DESCRIPTION: An otherwise healthy 61-year-old woman presented with mental status changes (MMSE-0) after 6 days of severe vomiting. Extracellular dehydration, hyponatremia (107 mmol/L), low levels of natriuresis, and mild hypokalemia were noted. The initial computed tomography (CT) of the brain was normal. Over 36 hours of hospitalization in a district hospital she developed unusual neuropsychiatric disorders: hypersexuality, hyperorality, absence, visual agnosia, sensory aphasia, amnesia, and depression typical of KBS. She was then transferred to a neurology department. Clear improvement was visible 3 months later: MMSE-22, moderation of hypersexuality and hyperorality, partial correction of amnesia and aphasia, regression of visual agnosia. But the prosopagnosia (face blindness) persisted, and the patient remained unable to differentiate positive and negative facial expressions. DISCUSSION: Intracranial mass, epilepsy, neuromeningeal infection and head trauma were all ruled out. Antiepileptic and antiherpetic agents were tested without success. There was no evidence of adrenal insufficiency or inappropriate vasopressin secretion. Only severe vomiting, corrected by water intake, could explain the hyponatremia. The first MRI showed bitemporal edema; 3 months later it showed large bitemporal lesions, both internal and external, with atrophy of the hippocampus and limbic system. These MRI findings are characteristic of KBS. To our knowledge, this is the only the second case of KBS with bitemporal myelinolysis reported related to excessively rapid correction of hyponatremia (increase of 30 mmol/L over 36 h), which leads more usually to central pontine myelinolysis.

Laparoscopic donor nephrectomy: meeting the challenge of consumerism?

BACKGROUND: Despite the increasing adoption of laparoscopic donor nephrectomy, no study has examined donor perceptions following this procedure. In particular, it has been tacitly assumed that a less invasive procedure might in itself provide a more satisfactory donor experience. The present study reviews the experience of donors undergoing laparoscopic nephrectomy, and examines the extent to which contemporary management practice addresses issues relevant to consumerism. METHODS: Forty-two donors participated in a structured telephone interview, and 33 (79%) returned a written questionnaire. RESULTS: Coming through the survey was a strong sense of commitment to donation, and most respondents were satisfied with the experience. The main criticisms related to hotel services, the duration of the preoperative investigations, the perceived quality of nursing care on the general wards, medical communication and the duration of postoperative follow up. The self-reported time to meet recovery goals was extremely broad. CONCLUSIONS: Considering the nature of criticisms offered by the respondents, it is concluded that the expectations of donors as health-care consumers will only be met through modification of existing protocols.
