Many objects create penetrating cranial injuries. Metallic objects and low velosity missiles are the most common offenders. Wood as wounding agent of the brain, has some characteristics. It has profound risk of infection, a significant propensity to fragmentation that is virtually undetechable on routine X-ray screening and very low atteunation value in CT scan. Because of its characteristics and rarity, we report a case of penetrating cranial injury by a wooden foreign body with review of literature.

Gadolinium contrast agents (CAs) are integral components of clinical magnetic resonance imaging (MRI). However, safety concerns have arisen regarding the use of gadolinium CAs, due to their association with nephrogenic systemic fibrosis (NSF). Furthermore, recently the long-term retention of Gd²⁺-based CAs in brains patients with normal renal function raised another possible safety issue. The safety concerns of Gd²⁺-based CAs have been based on the ligand structure of Gd²⁺-based CAs, and findings that Gd²⁺-based CAs with linear ligand structures showed much higher incidences of NSF and brain retention of CAs than Gd²⁺-based CAs with macrocyclic ligand structure. In the current study, we report the in vivo biodistribution profile of a new highly stable multifunctional Gd²⁺-based CA, with macrocyclic ligand structure (HNP-2006). MR imaging using HNP-2006 demonstrated a significant contrast enhancement in many different organs. Furthermore, the contrast enhanced tumor imaging using HNP-2006 confirmed that this new macrocyclic CA can be used for detecting tumor in the central nervous system. Therefore, this new multifunctional HNP-2006 with macrocyclic ligand structure shows great promise for whole-body clinical application.

BACKGROUND: We postulate that a delay in the implementation of hepatic arterial embolization for traumatic liver injury patients will negatively affect patient prognosis. Our work also seeks to identify factors related to the mortality rate among traumatic liver injury patients. METHODS: From January 2008 to April 2014, patients who had been admitted to the emergency room, were subsequently diagnosed with traumatic liver injury, and later underwent hepatic arterial embolization were included in this retrospective study. RESULTS: Of the 149 patients that underwent hepatic arterial embolization, 86 had the procedure due to traumatic liver injury. Excluding the 3 patients that were admitted to the hospital before procedure, the remaining 83 patients were used as subjects for the study. The average time between emergency room arrival and incidence of procedure was 164 min for the survival group and 132 min for the non-survival group; this was not statistically significant (p = 0.170). The average time to intervention was 182 min for the hemodynamically stable group, and 149 min for the hemodynamically unstable group, the latter having a significantly shorter wait time (p = 0.047). Of the factors related to the mortality rate, the odds ratio of the Glasgow Coma Score (GCS) was 18.48 (p < 0.001), and that of albumin level was 0.368 (p = 0.006). CONCLUSIONS: In analyzing the correlation between mortality rate and the time from patient admission to arrival for hepatic arterial embolization, there was no statistical significance observed. Of the factors related to the mortality rate, GCS and albumin level may be used as prognostic factors in traumatic liver injury.

There are occasions when standard techniques of reconstructive surgery for traumatic injury, tumor resection, and correction of congenital anomalies cannot be used as a result of the unavailability of tissues, absence of healthy vascular pedicle or excessive morbidity in donor area. It is established that autogenous skin, muscle, bone, and other composite tissue can retain their viability in varying degree as a prefabricated `flap with vascular pedicle implantation and the survival rate of these flaps has increased with tissue expansion or PGE1 infusion. The purpose of this study was to demonstrate the reliability of the secondary or prefabricated rectus abdominis musculocutaneous flap, and to evaluate the effect of the several factors on the survival routes of these flaps. Fifty New Zealand white rabbits weighing from 250 to 350 gm were used for the study. On the abdominal area bipedicled skin flaps are elevated as a random pattern flaps and were prefabricated using with rectus muscle. The fifty flaps were studied. They were divided into the five groups as follows; group I, 10 x4 cm classic axial pattern transverse rectus abdominis muscle (TRAM ) flaps were made as a control group (n = 10); groupII, 10 x4 cm random pattern bipedicled skin flaps were prefabricated using right rectus muscle with the delay procedure(n = 10); group III, 5 x4 cm prefabricated musculocutaneous flap were made same as group II on the right, side, tissue expansion was performed on the left side (n = 10); group IV, same procedure was performed as group II, and in addition postoperative intravenous infusion of PGE1 was given(n = 10); group V, same procedure was performed as group III, and in addition postoperative intravenous infusion of PGE1 and tissue expansion was performed(n = 10). Flap survival rates of each group were evaluated and compared. The following results were obtained: 1. Survival rates of prefabricated flaps were lower than that of classic axial pattern flaps regardless of using tissue expansion and PGE1 infusion(p < 0.05). 2. In making a comparison between flap with and without PGE1 infusion, survival rates of prefabricated flaps infused with PGE1 were higher than that of flaps without PGE1 infusion. 3. The prefabricated flaps managed with tissue expansion had higher survival rates than that of flaps without using tissue expansion. 4. The survival rates of prefabricated flaps managed in combination with tissue expansion and PGE1 infusion were significantly higher than that of other groups except control group. In conclusion, this study demonstrated the significance of combiring use of tissue expansion and PGE1 infusion in a prefabricated musculocutaneous flaps as a reliable method.

Since patients with intracranial neoplasms usually represent their neurological symptoms rather early in the course of the disease, sudden unexpected death due to intracranial neoplasms is an uncommon event seen only exceptionally in medicolegal autopsy practice. Although meningiom is one of the most common primary intracranial neoplasms, sudden death due to the tumor is an uncommon event. We report a sudden, unexpected death of a 56-year-old female with an undiagnosed olfactory groove meningioma. It is assumed that peritumoral edema is related to the sudden death among the several mechanisms.

A seaman died after a jet of compressed air directed to his anus while working with his colleagues in deck of the ship. He suffered from abdominal pain and distension, and died 5 hours later in the ship. Autopsy was performed and revealed rupture of the splenic flexure of the colon and partial seromuscular tearing in the rectosigmoidal region. We concluded that the cause of death was tension pneumoperitoneum by the pneumatic colonic rupture. The need for education of the workers handling compressed air appliances is emphasized.

Hypopharyngeal perforation associated with traffic accident is a rare occurrence, which can cause serious morbidity and mortality if not diagnosed and treated early. We report an autopsy case of hypopharyngeal perforation following a traffic accident. A 32-year-old man hits his chin when his car hits highway guardrail. He complained continuous neck pain and died 5 days after the accident. Autopsy was performed, and death was due to undiagnosed retropharyngeal abscess with sepsis.

The incidence of sudden death due to undiagnosed primary intracranial tumor is very low in forensic autopsy practice. The ganglioglioma is a well differentiated, slow growing primary brain tumor that is encountered predominantly in childhood. We report a sudden, unexpected death in a 6-year-old girl from a ganglioglioma. On autopsy, there was an intraventricular tumor with recent hemorrhage, occupying the anterior aspect of the lateral ventricle and resulting in hydrocephalus. Acute intratumoral hemorrhage appears to be the mechanism of sudden death.

A rare case of teratoma occuring in the posterior cranial fossa is reported. The tumor was partially encapsulated, and a surgical removal was accomplished. Teratoma is defined as a true tumor, composed of several types of tissues representing more than one germinal layer, which are foreign to the part in which it arises. The literature on teratomas located in the posterior cranial fossa is reviewed.
