Needle-fish are slender silvery fish with long pointed beaks. They are commonly seen swimming beneath the surface near fringing reefs in the Indo-Pacific area. Such areas are also frequented by Melanesian villagers. The speed of needle-fish, together with their tendency to leap out of the water when bright lights are used for fishing and at other times, occasionally result in deep, penetrating injuries to swimmers, waders, and, in particular, to fishermen who are working at night from small canoes. Injuries from needle-fish are a relatively common occupational hazard of subsistence village life in Oceania, and probably also for some fishermen in other coastal environments, such as those in Japan and Malaysia.
A 66-year-old man sustained an injury to his right foot while gardening. Despite receiving tetanus toxoid one hour later and adequate wound toilet, he developed severe tetanus complicated with autonomic dysfunction six days later. He died 20 days after admission. This case shows that tetanus toxoid alone may not be sufficient to prevent tetanus in wounded patients. Careful consideration must be given to the immune status of the patient and to the nature of the wound sustained. Incompletely immunised patients or patients with unknown immune status who sustain a tetanus prone wound should be protected with both tetanus toxoid and tetanus immunoglobulin.
A case of unsuspected penetrating cardiac injury is presented. It was recognised by the presence of bleeding into peritoneal cavity even after the source of bleeding from intra-abdominal organs had been stopped. It highlights the importance of high index of suspicion of associated cardiac injury in high epigastric penetrating injury.
A 16 year-old man presented with fracture of both his femurs after a road traffic accident. Chest radiograph revealed mediastinal widening. Subsequent CT scan and arch aortogram confirmed the findings of traumatic aortic arch transection at the isthmus. He underwent successful surgical repair. High index of suspicion and prompt actions are important in managing this potentially fatal but treatable condition.
Penetrating neck trauma present difficult management issues by virtue of their rarity. Undiagnosed laryngotracheal injuries have serious implications, especially in the context of multiple trauma, where other injuries overshadow that of the laryngotracheal complex. This is a case of a schizophrenic patient with multiple self-inflicted cuts on his throat and abdomen. Injuries include open, comminuted laryngeal complex lacerations with vocal cord avulsion, as well as evisceration of small bowel. Adequate assessment using both direct laryngoscopy and rigid endoscopy, coupled with open exploration, allowed optimal exposure and fixation of the larynx in the anatomical configuration. The post-operative outcome of the airway and voice remained satisfactory at follow-up. A high index of suspicion coupled with adequate surgical approach allowed establishment of a functional larynx.
The effect of supplementing 200 mg/kg body weight palm vitamin E (PVE) and 200 mg/kg body weight alpha-tocopherol (alpha-Toc) on the healing of wounds in streptozotocin-induced diabetic rats was evaluated. The antioxidant potencies of these two preparations of vitamin E were also evaluated by determining the antioxidant enzyme activities, namely, glutathione peroxidase (GPx) and superoxide dismutase (SOD), and malondialdehyde (MDA) levels in the healing of dermal wounds. Healing was evaluated by measuring wound contractions and protein contents in the healing wounds. Cellular redistribution and collagen deposition were assessed morphologically using cross-sections of paraffin-embedded day-10 wounds stained according to the Van Gieson method. GPx and SOD activities as well as MDA levels were determined in homogenates of day-10 dermal wounds. Results showed that PVE had a greater potency to enhance wound repair and induce the increase in free radical-scavenging enzyme activities than alpha-Toc. Both PVE and alpha-Toc, however, were potent antioxidants and significantly reduced the lipid peroxidation levels in the wounds as measured by the reduction in MDA levels.
We present a case of a foreign body which migrated to the maxillary ostia by mucociliary action from its initial location on the floor of the maxillary sinus where it was traumatically introduced. This report illustrates that a powerful mechanism of mucociliary action can cause relatively heavy objects within the maxillary sinus to migrate naturally to the sinus ostia against gravitational force.
Coronary sinus perforation is a relatively uncommon but much feared complication that may occur during the placement of left ventricular pacing lead. Coronary sinus perforation, especially in the presence of an obstructive flap, usually indicates the need to abandon the implantation attempt, as there are difficulties in crossing the obstructive flap as well as uncertainty of whether the lead is in the true lumen or into the pericardial space. We describe our experience in successfully placing the left ventricular lead safely despite the problems arising from these circumstances.
Acute laryngeal injury is a rare, potentially lethal injury. It often poses difficulty in airway management. Commonly described are external laryngeal or blunt injuries. We report a case of penetrating neck injury resulting in complete transection of cricoid cartilage. A lady presented with a large, deep slash wound in her neck from a knife injury. There was complete laryngotracheal separation. The airway was secured before she was taken to the operating theatre. A tracheostomy was performed. Exploration revealed the cricoid ring was cut horizontally into two. Anastomosis of the cartilaginous framework was undertaken. Fibreoptic laryngoscopy showed bilateral vocal cords paralysis. After two months the patient recovered without airway compromise, she regains her voice. Repeat laryngoscopy showed good mobility of the vocal cords. In conclusion surgical reconstruction should be meticulously done to ensure good respiratory and phonatory abilities.
We report a case of a young man who presented with a left-sided pneumothorax after suffering an accidental penetrating injury by a sewing needle to the anterior chest wall. Chest radiograph and the computed tomography of the thorax revealed that the needle was in the pleural cavity and there was an associated pneumothorax. An attempt at retrieval by direct incision failed. The sewing needle was successfully retrieved by a medical pleuroscopy. The patient recovered without any consequences and was discharged home after 24 hours of observation.
Marjolin's ulcers are malignancies that arise from previously traumatised, chronically inflamed or scarred skin. We present a case with childhood burns, who had repeated irritation of his forearm skin with palm oil thorns that eventually led to malignant change.
Penetrating injuries to bladder occur in 20 % of cases. Synchronous bladder and rectal perforation occur in 30-64 % of cases. The management of rectal and bladder injuries depend on whether it is an extra-peritoneal or intra-peritoneal injury. We hereby, report a case of penetrating trauma in a 13 year old boy who fell off a tropical fruit (Rambutan - Nephelium lappaceum) tree. He sustained an extra-peritoneal rectal injury with intra-peritoneal bladder injury. The rectal injury was repaired primarily via per anal route while the bladder injury needed an open repair following laparotomy. Upon removal of bladder clots, a leaf of the ‘Rambutan’ tree was found intra-vesically. It was removed and bladder repaired as per standard method. We review the literature on rare intra-vesicle foreign bodies and discuss the treatment of synchronous rectal and bladder injuries.
Emergency lung resection for chest trauma is a rare event with a reported incidence of 0.08-1.3% but is associated with a high morbidity and mortality especially if a pneumonectomy is required, if due to blunt chest trauma or when concomitant injuries are present. We report three cases of young adult males with penetrating chest injuries that required emergency thoracotomy (ET) and anatomical lung resection to achieve definitive control of life threatening pulmonary haemorrhage. All patients survived to hospital discharge and remained well on follow-up. Indications for an ET and what constitutes the optimal operative management of such patients is discussed.
Peripheral vascular injuries result from penetrating or blunt trauma to the extremities. We describe here an unusual cause of a radial artery injury by the spine from the pectoral fin of Pangasius sutchi in a 51 year-old man and we review the literature.
Concurrent penetrating injury to the male external genitalia and the anterior urethra is uncommon. This case illustrates an unusual cause of such an injury, and its subsequent management and outcome. A 69-year-old man had his scrotum and anterior urethra pierced by a long thorn when he fell in his farm. He presented with urine leakage from the scrotal wound each time he micturated. Cystoscopic examination confirmed the cause and extent of the injury, and also facilitated the extraction of the thorn. The injury was allowed time to heal by urinary diversion with a urinary catheter. There were no stricture or fistula formations and the patient remained symptom-free at 3 months follow-up. Careful cystoscopic examination was both diagnostic and therapeutic in this case. A conservative approach is a feasible option in the management of selected cases of penetrating anterior urethral injury.
Skin grafting has been evolving as an important application in reconstructive surgery. Mixed reports about the survival of allogeneic and xenogeneic keratinocytes require further substantiation to determine the role of these cells in wound healing.
