Dermal Skin Substitutes for Upper Limb Reconstruction: Current Status, Indications and Contraindications

Dermal skin substitutes are a group of biologically engineered materials composed of collagen and glycosaminoglycans and are devoid of cellular structures. These biodegradable materials act as an artificial dermis to promote neovascularization and neodermis formation. Their applications in soft tissue reconstructions are rapidly expanding. In this article, the indications, advantages, and limitations of dermal skin substitutes for reconstruction of soft tissue defects of the upper extremity are reviewed.

Post-traumatic skin and soft tissue infection due to Aeromonas hydrophila.

We report a case of posttraumatic skin and soft tissue infection in a patient who sustained laceration after being hit by a water tanker. Aeromonas hydrophila was isolated from pus and was identified to the species level by Vitek 2 and a battery of biochemical tests. The patient responded to thorough drainage, debridement of wound and 2 weeks of intravenous antibiotics. The patient was taken up for split skin grafting of the raw area. She was discharged with satisfactory graft uptake after 1 week without any further antibiotics advice. Follow-up after 3 weeks was satisfactory with healthy cover on the raw area and normal weight bearing on the left leg.

Nonoperative Management of Traumatic Chylothorax

Chylothorax is known for its rarity, and its diagnosis following blunt chest trauma is exceptional. Only a small number of cases have been reported in the literature. Severe consequences, such as cardiopulmonary abnormalities and metabolic, nutritional, and immunologic disorders, can result from chylothorax. Management of chylothorax is challenging. It can either be managed nonoperatively or surgically. Surgical treatment is required in cases of persistent or high output fistulae. We report here in three cases of blunt trauma chest following road traffic crash associated with chylothorax. All of them were successfully managed nonoperatively with inter costal tube drainage and supportive treatment sans need of any operative intervention.

Subcutaneous mercury injection by a child: A histopathology case report

Intentional subcutaneous injection of mercury by mentally healthy children is rare. Usually, it is seen as a part of suicidal attempt in severely depressed patients or by athletes to enhance their performance. We report a case of a 15-year-old child, inspired by a movie, who deliberately self-injected mercury subcutaneously into his forearm that led to the formation of a non-healing ulcer. Histopathology of the biopsy confirmed the diagnosis. A surgical procedure was thereby performed to treat the ulcer and reduce the blood and urinary levels of mercury. However, the patient did not develop clinical signs of chronic poisoning, proving that subcutaneous mercury injection has a low risk of systemic toxicity, and that histopathology plays an important role in diagnosis.

Operative management of splenic injury in a patient with proteus syndrome.

A 20-year-old female with Proteus syndrome sustained splenic injury after fall from a bike. She was initially managed non-operatively at a different hospital for three days and was then referred to our level I trauma center in view of increasing abdominal pain and distention. On admission in the Emergency Department (ED), her pulse rate was 120 per minute and blood pressure was 108/68 mm Hg. Clinical examination showed a distended abdomen with left hypochondrial pain. Ultrasonogram (USG) and Computed Tomography (CT) of the abdomen showed splenomegaly and grade III splenic injury with significant hemoperitoneum. Her hemoglobin was 2.9 g/dl with packed cell volume (PCV) of 12%. In view of low hemoglobin and possibility of pathologic spleen, splenectomy was done. Microscopic examination of the spleen showed hemangiolymphangioma. The patient was discharged on the 5th post-operative day and is doing well at 6 months of follow-up.

Burden of maxillofacial trauma at level 1 trauma center.

There is an upward trend in facial injuries following changes in population pattern, increasing industrialization and urbanization, hence maxillofacial trauma is becoming a burden and a leading medical problem in emergency rooms worldwide. This study was performed to evaluate the pattern of maxillofacial fractures, associated injuries, and treatment used at Jai Prakash Narayan Apex Trauma Center (JPNATC), All India Institute of Medical Sciences (AIIMS), New Delhi, India, between January 2007 and June 2010. The study provides basis for establishment of trauma as major etiology of maxillofacial injuries and planning for preventive strategies. A retrospective study of patients seen and treated at JPNATC, AIIMS, New Delhi, between January 2007 and June 2010 was performed. Data extracted from patient records included etiology, age, sex, types and sites of fractures, treatment modality, and concomitant injuries. There were 795 fractures of the maxillofacial skeleton and 86 concomitant injuries from 542 patients. Road traffic accident (RTA) (56.8%) was the most common etiologic factor, followed by falls (22.3%) and fights (18.5%). The age range was from 3 to 75 years (mean, 34.7 years) with a peak incidence in the third decade with a male-to-female ratio of 3.7:1. The most common location of maxillofacial fractures was the mandible 615 (77%) and middle third 180 (23%). With regard to mandibular fractures, the body (29.6%) was the most common site, followed by the angle (24.4%), ramus (19.5%), dentoalveolar (14.6%), symphysis (11.0%), condyle (0.8%) while in the middle third, the nasal bone (36.7%) was the most common, followed by zygomatic bone (27.8), Lefort II (14.4), Lefort I (7.8%), dentoalveolar (10.0%), and Lefort III (3.3%). Majority of the patients were treated by open reduction and internal fixation (70.6). Concomitant injuries were 84 (10.8%) with orthopedic injuries accounting for the majority (63.9%). Head injury was associated in 16.3% of cases. RTA was the major etiologic factor of maxillofacial injuries in our setting and the young adult males were the main victims. Henceforth, establishment of regionalized, efficient, and focused trauma centers in various parts of the country particularly for acute trauma should be emphasized. Also, the laws regarding the precautions such as seat belts, speed limits, and traffic rules must be observed strictly to reduce the incidence of RTA.

Gastroduodenal artery aneurysm – A rare complication of traumatic pancreatic injury

Aneurysm of gastroduodenal artery (GDA) is rare. Most reported cases are due to pancreatitis and atherosclerosis; however, those following pancreatic trauma have not been reported. We encountered GDA aneurysm in a patient of blunt abdominal trauma, who had pancreatic contusion and retroduodenal air on contrast enhanced computed tomography of abdomen. Emergency laparotomy for suspected duodenal injury revealed duodenal wall and pancreatic head contusion, mild hemoperitoneum and no evidence of duodenal perforation. In the postoperative period, the patient developed upper gastrointestinal hemorrhage on day 5. Repeat imaging revealed GDA aneurysm, which was managed successfully by angioembolization. This case highlights, one, delayed presentation of GDA aneurysm after blunt pancreatic trauma and two, its successful management using endovascular technique.

Effectiveness of insecticide-treated and untreated nets to prevent malaria in India.

India is the most malaria‐endemic country in South‐East Asia, resulting in a high socio‐economic burden. Insecticide‐treated or untreated nets are effective interventions to prevent malaria. As part of an Indian first‐aid guideline project, we aimed to investigate the magnitude of this effect in India.

Post traumatic buccal fat pad injury in a child: a missed entity in ER.

Maxillofacial injuries in the paediatric age group is common and traumatic herniation of buccal fat pad represents one of the few sequel to facial injuries which can easily be missed during primary or secondary survey in the emergency department, especially in young patients. The uncommon occurrence and thus lack of knowledge, often alarms the parents and/or attending physian alike with the presence of a tumor like lesion within the oral cavity in the post-traumatic period. The following case report describes one such incidence of traumatic extrusion of the buccal fat pad into the oral cavity while addressing the need to reinforce the practice of thorough clinical examination before managing any patient.

Traumatic cardiac injury: Experience from a level-1 trauma centre

Purpose Traumatic cardiac injury (TCI) is a challenge for trauma surgeons as it provides a short therapeutic window and the management is often dictated by the underlying mechanism and hemodynamic status. The current study is to evaluate the factors influencing the outcome of TCI. Methods Prospectively maintained database of TCI cases admitted at a Level-1 trauma center from July 2008 to June 2013 was retrospectively analyzed. Hospital records were reviewed and statistical analysis was performed using the SPSS version 15. Results Out of 21 cases of TCI, 6 (28.6%) had isolated and 15 (71.4%) had associated injuries. Ratio between blunt and penetrating injuries was 2:1 with male preponderance. Mean ISS was 31.95. Thirteen patients (62%) presented with features suggestive of shock. Cardiac tamponade was present in 12 (57%) cases and pericardiocentesis was done in only 6 cases of them. Overall 19 patients underwent surgery. Perioperatively 8 (38.1%) patients developed cardiac arrest and 7 developed cardiac arrhythmia. Overall survival rate was 71.4%. Mortality was related to cardiac arrest (p = 0.014), arrhythmia (p = 0.014), and hemorrhagic shock (p = 0.04). The diagnostic accuracy of focused assessment by sonography in trauma (FAST) was 95.24%. Conclusion High index of clinical suspicion based on the mechanism of injury, meticulous examination by FAST and early intervention could improve the overall outcome.
