AbstractStereotactic biopsy is a common minimal access neurosurgical procedure. It requires a stereotactic frame to be secured on the head, and thereafter, based on computerised tomography scan markings on the frame, precise biopsy is retrieved. For anaesthesiologists, the application of frame poses difficulty in accessing the upper airway with the conventional laryngoscopy-intubation methodology. The various airway-access limitations imposed by an ‘in-place’ frame can be problematic and should be addressed. This report elucidates the problems caused by the presence of stereotactic frame in the management of upper airway. The approach to upper airway can be variable on a case-to-case basis, depending on attending anaesthesiologists’ decision-making and availability of equipments/devices. Here, the, recommendations on the problematic points and the suggested way thereof are presented.

Facial lacerations are a common presentation in emergency departments. It is important to appreciate the mechanism of injury and the anatomy of structures involved in penetrating lacerations in the maxillofacial region. A 65-year-old man suffered an accidental penetrating injury with a sharp kitchen knife to the right temporal region. There was a single laceration to the right temporal region. The right eye had no perception to light, a total afferent and efferent pupillary defect and partial ophthalmoplegia. Computerised tomography scan revealed signs of penetration through the skin, temporalis, postero-lateral orbital wall and orbital apex. There was no injury to the globe or either retrobulbar or intracranial haemorrhage. A diagnosis of direct traumatic optic neuropathy was made following consultation with opthalmology and neurosurgery teams. Only two similar cases of penetrating trauma in the temporal region resulting in direct traumatic optic neuropathy have been identified in the literature. This case presentation highlights the structures that are at risk of damage from penetrating trauma in the maxillofacial region.

Case Basis

Anthropogenic modifications to aquatic ecosystems have altered connecting pathways within, and in some cases, between watersheds. Human structures, such as hydroelectric facilities, often impede fish migrations and may inflict heavy mortality on fish that become impinged or entrained. Conversely, an increase in connectivity between two waterways (e.g., through the construction of shipping canals, increased boat traffic) often results in an elevated risk of invasive species introductions. Non-physical barriers, which obstruct fish from an undesirable location without influencing the waterway, are one management approach to protecting valuable fish stocks and deterring biological invasions. Because many methods of behavioral deterrence have been employed against fish, there is a need to summarize and compare existing and developing technologies. This review details the use and application of electrical, visual, acoustic, chemical, and hydrological deterrence techniques that may be used to prevent fish movements. Site requirements are discussed, and a critical assessment of benefits and limitations to each technique are given. Because no single method of fish deterrence is “one size fits all”, this review to non-physical fish barrier technology will benefit managers and researchers attempting to develop a best-fit strategy on a case-by-case basis.

Acute upper airway obstruction can be fatal. Early recognition of airway distress followed by diagnostic laryngoscopy and prompt intervention to secure airway control is crucial. We here present a 62-year old male patient who presented with cough and increasing respiratory distress for three weeks. Within the next 24 h, he developed symptoms of critical upper airway obstruction, endotracheal intubation was not possible, and an acute surgical tracheotomy was performed to retain patent airways. A computer tomography scan revealed severe laryngopharyngeal soft tissue thickening and upper airway obstruction caused by leukemic infiltration. He was diagnosed with acute leukemia and responded to induction chemotherapy. This case report points out the importance of establishing the diagnosis of critical upper airway obstruction in patients presenting with respiratory symptoms, and highlights the emergency management of airway obstruction due to malignant infiltration of leukemic blasts.

AbstractA three-year old bot wiht a swelling on the right side of his neck was suspected of having parapharyngeal abscess after clinical examination and CT scan(computed tomography scan) of this region. Later it became clear, that the swelling was caused by an aneurysm of the internal carotid artery. This case report describes the pitfalls and difficulties encountered in the diagnostic course and treatment planning.

Pediatric patients undergoing chemotherapy may present upper airway obstruction due to severe oral mucositis. Although reversible, its clinical course correlates with the course of neutropenia and may be complicated. Thus, airway management in these patients must be determined on an individual case basis.

This report describes the case of an 83 years old woman presenting to hospital due to a fall, and acute confusion. On admission, she was diagnosed as having clinical and plain X-ray features of a pneumonia. Following treatment and recovery from the pneumonia, she was noted to have persistent clinical signs of bilateral lung crackles on auscultation. A high-resolution computerised tomography scan showed signs of interstitial lung disease consistent with pulmonary fibrosis. Of relevance was a medication history that indicated oral nitrofurantoin had been initiated in primary care for the long-term prophylaxis of recurrent urinary tract infections. Given the prolonged duration of use of ten years, we considered the possibility of this being an adverse drug reaction in the form of nitrofurantoin associated pulmonary fibrosis. This report also briefly reviews the relevant literature on nitrofurantoin associated pulmonary fibrosis and to promote objectivity in the pharmacovigilance related reporting. The report has been reviewed with the aid of two validated causality assessment systems.
