Neurobrucellosis as an exceptional cause of transient ischemic attacks

EUROPEAN JOURNAL OF NEUROLOGY, Issue 5 2006
A. Bingöl
We report a series of four cases presented with transient ischemic attacks (TIA) or ischemic stroke as the predominant manifestation of neurobrucellosis (NB). Three of the patients were 20,28 years of age, and one patient was 53 years old. They all used to consume unpasteurized milk or its products. Two patients had systemic brucellosis in the past and received antibiotic treatment. Other causes of TIA including cardiac embolism, hypercoagulability, vascular malformations, systemic vasculitis, and infective endocarditis were excluded. NB was diagnosed with serological tests or cultures for Brucella in the cerebrospinal fluid. None of the patients had any further TIA after the initiation of specific treatment. NB should always be sought in young patients with TIA or ischemic stroke, especially if they have no risk factors for stroke and live in an endemic area for brucellosis, even if they do not have other systemic signs of brucellosis.

The Role of Acinetobacter baumannii as a Nosocomial Pathogen for Dogs and Cats in an Intensive Care Unit

JOURNAL OF VETERINARY INTERNAL MEDICINE, Issue 2 2000
Thierry Francey
Acinetobacter baumannii is a nosocomial pathogen associated with high morbidity and mortality in humans. Whereas infections with strains of Acinetobacter species have been reported in various situations, the importance of A baumannii as a nosocomial pathogen in veterinary hospitals has not been studied so far. In this retrospective case series, we describe 17 dogs and 2 cats from which A baumannii had been isolated during a 21/2-year period. In 7 dogs, A baumannii induced systemic signs of illness, whereas 12 animals showed signs of local infection. In all animals with systemic infection, and in 2 with localized infection, A baumannii contributed to the death of the animal or contributed to euthanasia; the remaining 8 dogs and both cats recovered. Molecular typing of the isolates with restriction polymorphisms of ribosomal DNA provided evidence of nosocomial spread of this pathogen and for the presence of several strains of A baumannii in the hospital environment.

Survey of epidural analgesia management in general intensive care units in England

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 7 2002
J. H. S. Low
Background: The management of epidural analgesia is controversial. Many intensive care unit (ICU) patients may benefit from this form of analgesia but have one or more contraindications to its use. Sepsis, coagulopathy, insertion in a sedated, ventilated patient, and lack of consent are common problems in ICU patients. Little has been published to help guide practice in this area. I wished to establish the current practice of the management of epidural analgesia in general ICUs in England when relative or absolute contraindications occur, in order to determine the current standard of care for placement and use of epidural analgesia in ICU patients. Methods: A postal questionnaire survey of the management of epidural analgesia in critically ill patients was sent to the named clinical director of all (216) general ICUs in England. Results: Responses were received from 159 (75%) units: 89% of responding units use epidural analgesia but only 51(32%) have a written policy covering its use. Anesthetists or intensivists with an anesthetic background sited all epidural catheters; 68% of units would not site an epidural in a patient with positive blood cultures; but only 52% considered culture negative sepsis (systemic signs of sepsis with no organism isolated) to be a contraindication. Neither lack of consent nor the need for anticoagulation after the catheter had been sited were considered contraindications to inserting an epidural catheter by the majority of respondents. Although 71% of the units would remove an epidural catheter if a patient developed positive blood cultures after it had been sited, the majority of the ICUs did not consider culture negative sepsis and the need for anticoagulation contraindications to maintain a previously sited epidural. Conclusions: Practice varied considerably with little consensus. Although all the respondents use epidural analgesia in critically ill patients, the indications and contraindications to epidural analgesia remain controversial, and further research is required to help define the role of epidural analgesia in this high-risk group.

Big snake, small snake: which wound is worse when bitten?

ACTA PAEDIATRICA, Issue 8 2009
Kam-Lun Ellis Hon
Abstract Snakebites in children and teenagers are relatively uncommon in the metropolitan city of Hong Kong. They are rarely fatal but may cause significant morbidity and fear. We report two cases of snakebites to illustrate that the spectrum of morbidity is independent of the size of the snakes. A 7-year-old boy was bitten in successions by a green snake. Envenomation occurred at the second bite site. He developed local and systemic signs that were promptly relieved with anti-venom therapy at the intensive care unit. An 18-year-old girl was bitten by a large python but only sustained minor local soft tissue injuries. This report serves to alert the public that snake may bite in successions and envenomation may occur with the subsequent bite. Conclusion:, A small snake may be venomous and a large snake may not be. Avoidable risk factors associated with snakebites (such as avoiding areas known to harbour snakes in the evening in summer and autumn and wearing protective footwear) are highlighted. [source]
