This study examined the effects of early burn wound excision on gastric blood flow and on morphologic changes in mucosal vessels. Wistar rats were given a 30% total body surface area burn and divided into four groups, consisting of control animals (group 1), animals with burn injury without and with fluid resuscitation (groups 2 and 3, respectively), and animals with both fluid resuscitation and early wound excision (group 4). Gastric mucosal blood flow (GMBF) was measured by the hydrogen gas clearance method up to 24 h post-burn. ⋯ In group 4, however, it recovered to the initial value by 6 h post-burn and there was no significant change throughout the experiment. Morphologically, although the mucosal capillaries revealed some changes such as irregularity in diameter in groups 2-4 at 3 h, most of mucosal capillaries retained their original appearance in group 4 at 24 h post-burn. These result suggest that early excision does not aggravate the state of gastric ischemia.

A 39 year old white male with a 55% total body surface burn who developed neuroleptic malignant syndrome (NMS) during his acute course is reported. The patient had several acute sinusitis and septic episodes during his acute course. On postburn day 31, he developed a temperature of 108.4 degrees F (42.4 degrees C). ⋯ His recovery was uneventful. NMS is a drug-related response to various medications, such as Haloperidol, which the patient was receiving. NMS must be considered as part of the differential diagnosis of fever in burn patients receiving medication known to cause the syndrome.

Comparative Study
Plasma levels of type II phospholipase A2 and nitrite/nitrate in patients with burns.
Type II phospholipase A2 (type II PLA2), nitrite/nitrate (NOx), tumor necrosis factor-alpha (TNF-alpha) and endotoxin were studied in burn patients. Type II PLA2 values and NOx values were both significantly higher in the group that died, the group with shock as a complication and the group with multiple organ dysfunction syndrome (MODS) as a complication, than in the group that survived, the group without shock as a complication and the group without MODS as a complication, respectively. The results suggested that type II PLA2 and nitric oxide (NO) may play a major role in the pathology of burn patients. Significant correlations were found between TNF-alpha and type II PLA2 values and between type II PLA2 and NOx values, suggesting the possibility of involvement in each other's production.

Comparative Study
Detection of capillary protein leakage by glucose and indocyanine green dilutions during the early post-burn period.
Overestimation of the plasma volume determined by the indocyanine green (ICG) dilution method (PV-ICG) may occur after burns, since this dye has the potential of extravasation in the presence of the capillary protein leakage. Assuming that the initial distribution volume of glucose (IDVG) consistently indicates the extracellular fluid volume of highly perfused organs including plasma, overestimation of the PV-ICG can be detected by a higher PV-ICG/IDVG ratio. The present study was designed to test whether a higher PV-ICG/IDVG ratio is observed within 24 h post-burn compared to the subsequent days. ⋯ Although the IDVG increased on the 1st post-burn day (p < 0.05), the PV-ICG remained unchanged. The PV-ICG/IDVG ratio within 24 h post-burn was significantly higher than that on the 1st post-burn day (p < 0.01). Results indicate that overestimation of the PV-ICG can occur within 24 h post-burn and suggest that simultaneous measurement of the IDVG and the PV-ICG would help predict the generalized capillary protein leakage after burns.

Comparative Study
Recreational-outdoor burns: the impact and severity--a retrospective review of 107 patients.
Campfires, bonfires and barbecues play a prominent role in outdoor activities and serve a variety of decorative and functional purposes. Given all of it's various forms, uses and benefits, the outdoor fire can turn dangerous in a matter of seconds: a stumble or fall (the child running that trips) leads to direct contact with the flames and subsequent burn injury. With it's everyday occurrence, we were surprised to find a paucity of information regarding this type of burn in the literature, including the NBIE analysis. ⋯ Recreational outdoor burns were extremely common injuries leading to loss of functional employment and prolonged physical therapy requirements. Small children and intoxicated adults comprised the majority of our study population. The impact and severity of such outdoor fires could be greatly affected by appropriate attention to prevention.
