Accurate determination of the wound depth has long been a difficult task in forensic medicine due to lack of technology. Nowadays, the depth of the wound can be accurately determined by using high frequency 2-D ultrasound and Color Doppler Flow Imaging (CDFI). Two typical cases with ultrasonic images were reported to show the importance of ultrasound technology in forensic medicine. The new technology provides scientific evidence of the injury assessment.

Although penetrating neck trauma (PNT) is uncommon, it is associated with the significant morbidity and mortality. The management of PNT has changed significantly over the past 50 years. A radiological assessment now is a vital part of the management with a traditional surgical exploration. A 22 years old male was assaulted by a screwdriver and sustained multiple penetrating neck injuries. A contrast CT scan revealed a focal pseudoaneurysm in the left common carotid artery bulb. There was no active bleeding or any other vascular injuries and the patient remained haemodynamically stable. In view of these findings, he was initially managed conservatively without an open surgical exploration. However, the patient was noted to have an acute drop in his hemoglobin count overnight post injury and the catheter directed angiography showed active bleeding from the pseudoaneurysm. Surgical exploration 40 hours following the initial injury revealed a penetrating injury through both arterial walls of the left carotid bulb which was repaired with a great saphenous vein patch. A percutaneous drain was inserted in the carotid triangle and a course of intravenous antibiotics for five days was commenced. The patient recovered well with no complications and remained asymptomatic at five months followup.

PURPOSETraumatic diaphragmatic rupture (TDR) needs early diagnosis and operation. However, the early diagnosis is usually difficult, especially in the patients without diaphragmatic hernia. The objective of this study was to explore the early diagnosis and treatment of TDR.

METHODSData of 256 patients with TDR treated in our department between 1994 and 2013 were analyzed retrospectively regarding to the diagnostic methods, percentage of preoperative judgment, incidence of diaphragmatic hernia, surgical procedures and outcome, etc. Two groups were set up according to the mechanism of injury (blunt or penetrating).

RESULTSOf 256 patients with a mean age of 32.4 years (9-84), 218 were male. The average ISS was 26.9 (13-66); and shock rate was 62.9%. There were 104 blunt injuries and 152 penetrating injuries. Preoperatively diagnostic rate was 90.4% in blunt injuries and 80.3% in penetrating, respectively, P < 0.05. The incidence of diaphragmatic hernia was 94.2% in blunt and 15.1% in penetrating respectively, P < 0.005. Thoracotomy was performed in 62 cases, laparotomy in 153, thoracotomy plus laparotomy in 29, and combined thoraco-laparotomy in 12. Overall mortality rate was 12.5% with the average ISS of 41.8; and it was 21.2% in blunt injuries and 6.6% in penetrating, respectively, P < 0.005. The main causes of death were hemorrhage and sepsis.

CONCLUSIONSDiagnosis of blunt TDR can be easily obtained by radiograph or helical CT scan signs of diaphragmatic hernia. For penetrating TDR without hernia, "offside sign" is helpful as initial assessment. CT scan with coronal/sagittal reconstruction is an accurate technique for diagnosis. All TDR require operation. Penetrating injury has a relatively better prognosis.

INTRODUCTIONThe aim of this study was to investigate the role of ultrasound biomicroscopy (UBM) in imaging anterior segment foreign bodies and compare it with conventional B-scan ultrasound and computed tomography (CT).

MATERIALS AND METHODSThe charts of 18 eyes with anterior segment foreign bodies were reviewed. The rates of detection of foreign bodies using ultrasound, CT scan and UBM were compared.

RESULTSThe foreign body detection rates were 36.5% by ultrasound, 88.9% by CT scan, and 94.4% by UBM. The diagnosis of presence of a foreign body using UBM was made based on high reflective echoes causing shadowing or reverberations. In 7 eyes, UBM detected injury to the zonules, guiding the operative procedure. In the 8 eyes for which all tests were performed, rates of detection of foreign bodies were 25% (2/8) with ultrasound, 87.5% (7/8) with CT, and 100% (8/8) with UBM.

CONCLUSIONUBM is a valuable adjunct for the accurate localisation of small foreign bodies, including cilia. It offers a higher detection rate than that provided by ultrasound and CT scan.

OBJECTIVETerrorism-related bomb attacks on civilian population have increased dramatically over the last decade. Craniocerebral injuries secondary to improvised explosive devices have not been widely reported in the context of unarmored civilians. This series intends to report the spectrum of these injuries secondary to suicidal and implanted bombs as encountered at the Aga Khan University Hospital, Pakistan (AKUH). Further, a few pertinent management guidelines have also been discussed.

METHODSThe hospital database and clinical coding during a 5-year period were examined for head injuries secondary to terrorism-associated blasts. In addition to patient demographics, data analysis for our series included initial Glasgow Coma Scale, presenting neurological complaints, associated non-neurological injuries, management (conservative or operative) to associated complications, and discharge neurological status.

RESULTSA total of 16 patients were included in this series. Among them 9 were victims of suicidal blasts while 7 were exposed to implanted devices. The patients presented with diverse patterns of injury secondary to a variety of shrapnel. A follow-up record was available for 12 of the 16 patients (mean follow-up: 7.8 months), with most patients having no active complaints.

CONCLUSIONThe results of this series show that civilian victims of suicidal and improvised bombings present with a wide range of neurological symptoms and injury patterns, which often differ from the neurological injuries incurred by military personnel in similar situations, and thereby often require individualized care.
