Garlic burns: a naturopathic remedy gone awry.

We report the case of a child who sustained partial thickness burns from a garlic-petroleum jelly plaster, which had been applied at the direction of a naturopathic physician. A review of the literature reveals that "garlic burns" have not previously been reported, although medicinal properties of garlic have been investigated by physicians and biochemists. The pediatrician caring for children in an area where naturopathic medicine is routinely practiced should be aware of the potential side effects of plasters, poultices, and other "natural" remedies in children.

Hospital stay following biliary tract surgery. A comparison of two community hospitals.

An apparent difference in length of postoperative hospitalization following biliary tract surgery at two university-affiliated community hospitals led to a retrospective review of 200 consecutive patients at each hospital. Patient characteristics and surgical practices that potentially affected hospital stay were compared. A highly significant difference was identified in the length of hospitalization between the two institutions. Statistically significant differences in variables that seemed to affect length of stay included the use of nasogastric tubes and abdominal drains and the time interval to the institution of postoperative feedings. Cumulative hospitalization was 517 days shorter at one institution. This was accomplished despite a high percentage of emergent procedures and more frequent involvement of surgical residents. Since hospital stay accounts for the majority of expenditure for surgical treatment of biliary tract disease, shortening postoperative hospitalization can significantly reduce the overall costs.

Prophylactic platelet administration during massive transfusion. A prospective, randomized, double-blind clinical study.

Prior studies at Harborview Medical Center have suggested that dilutional thrombocytopenia is a major etiology of microvascular, nonmechanical bleeding (MVB). We undertook a prospective randomized double-blind clinical study to compare the prophylactic effects of 6 units of platelet concentrates (PLT) versus 2 units of fresh frozen plasma (FFP) administered with every 12 units of modified whole blood in patients undergoing massive transfusion (12 or more units in 12 hours). After exclusions, three of 17 patients who received PLT and three of 16 patients who received FFP developed MVB, an incidence no different from our previous findings. Regression lines of platelet counts during transfusion were no different between groups, and both groups had higher platelet counts than predicted from a standard washout equation. Only one patient had evidence of dilutional thrombocytopenia as a cause for MVB. Prophylactic platelet administration is not warranted as a routine measure to prevent MVB.

Excision and grafting of large burns: operation length not related to increased morbidity.

In order to study the relation between length of operation and postoperative morbidity in patients with burns greater than 30% TBSA a retrospective review was done. Seven categories of morbidity were chosen and points assigned for significant change from the preoperative state. There were no intraoperative or immediate postoperative deaths. The overall morbidity was 19%. The eventual mortality was 19%. There was no correlation between length of operation and postoperative morbidity.

Excision of burns of the face.

Sequential excision of burns is now a common technique. Nevertheless, standard texts, when describing the treatment of facial burns, recommend allowing spontaneous separation of the eschar and then grafting on granulation tissue if healing does not occur. This method yielded disappointing results for us and the reconstructive procedures required were of great magnitude. Therefore, in January of 1979, we began primary excision and grafting of those face burns not essentially healed at 10 days. We have now treated 16 consecutive patients (approximately 5 percent of all face burns) in this manner who are at least 12 months postinjury. Three were lost to follow-up, leaving 13 for evaluation. This method yields better appearance and function than that obtained by allowing spontaneous healing over more than 3 weeks or grafting on granulation tissue and decreases the magnitude of subsequent reconstruction.

Pediatric patients in a regional burn center.

Because scald burns are reported to be the leading cause of burn injuries to children, little is written about other etiologies of burn injury in the pediatric literature. To test the hypothesis that burns from other etiologies are more serious and require longer hospitalizations than scald burns, a retrospective chart review was undertaken. The charts of all patients less than 16 years of age who were admitted to Harborview Medical Center Burn Unit in the years 1979 to 1984 were reviewed. Four hundred sixty-four children were admitted to the regional burn center during that time. We found that children under four years of age are at greatest risk for being hospitalized for thermal injury, that the burn most commonly occurs inside the home between 6 PM and midnight, and that scalds are the most common etiology for thermal injuries in children (54%). However, 46% of the burns resulting in admission to our burn center were from etiologies other than scald injury. There was no significant correlation between etiology of the burns and length of hospital stay, rate of infection, or need for excision and grafting. Thermal injuries to children from any etiology are serious; pediatric health care providers should be aware that children may be burned in a variety of ways and should direct some of their well-child visit time to the topic of burn prevention in the home.

Comparison of quantitative and semiquantitative culture techniques for burn biopsy.

Accurate evaluation of bacterial colonization as a predictive index for wound sepsis has relied on a quantitative culture technique that provides exact colony counts per gram of tissue by culture of five serial dilutions of biopsy tissue homogenate. The method, while useful to the physician, is both labor intensive and expensive. In this study 78 eschar biopsies were cultured by a semiquantitative technique that involved the use of 0.1- and 0.01-ml samples of inocula and by the serial dilution method. Exact colony counts from the semiquantitative culture method were available only from cultures containing 10(4) to 10(6) CFU/g of tissue. Other colony counts were reported as less than 10(4) or greater than 10(6) CFU/g. Agreement by category of colony counts between the two methods was 96%. For prediction of wound sepsis, the semiquantitative procedure had a positive predictive value of 100% and a negative predictive value of 93.7%. This method also resulted in an approximately 30% reduction of work units (as defined by the College of American Pathologists) and a 60% reduction in the amount of media for specimen processing. Therefore, this semiquantitative culture technique provides accurate information to the physician while saving both time and materials.

Management of Stevens-Johnson syndrome.

A patient with Stevens-Johnson syndrome is described, and the literature concerning the etiology, pathophysiology, clinical manifestations, and management of Stevens-Johnson syndrome is reviewed. A 2 1/2-year-old girl was treated with phenobarbital and i.v. ampicillin, followed by oral amoxicillin, for an upper-airway infection, otitis media, and febrile seizures. The fever returned, and she was treated unsuccessfully with penicillin and cefaclor. She was admitted to the hospital and treated with i.v. ampicillin. Within 24 hours an erythematous maculopapular rash developed. Phenobarbital was discontinued and phenytoin was begun. Four days later bullous lesions developed; ampicillin and phenytoin were discontinued, and cefazolin and phenobarbital were given. By the eighth day severe sloughing of the skin occurred over 75% of her body, and mucosal sloughing was apparent. The patient's condition was diagnosed as Stevens-Johnson syndrome. Porcine xenografts were immediately grafted to 75% of her total body surface. Severe lesions of the mouth and pharynx made parenteral nutrient therapy necessary, and ocular complications required the care of an ophthalmologist. Although the skin had healed by 14 days after grafting, another 14 days of treatment for respiratory complications was required. Stevens-Johnson syndrome is a severe exfoliative dermatitis accompanied by fever, inflammation of the gastrointestinal mucosa, and severe purulent conjunctivitis. It is associated with high morbidity and mortality. The etiologic factors may be iatrogenic (e.g., various antibiotics and anticonvulsants), infectious, or idiopathic. Respiratory complications, leukopenia, infections, erosion of the gastrointestinal mucosa, fluid and electrolyte disturbances, and chronic ocular complications may occur.(ABSTRACT TRUNCATED AT 250 WORDS)

Stratified outcome comparison of clindamycin-gentamicin vs chloramphenicol-gentamicin for treatment of intra-abdominal sepsis.

A randomized, prospective trial was conducted of 93 patients with operatively confirmed intra-abdominal sepsis. The study compared clindamycin-gentamicin and chloramphenicol-gentamicin for treatment of carefully stratified patient groups. Malnutrition, age over 65 years, shock, alcoholism, gastrointestinal tract bleeding, steroid administration, diabetes, obesity, and organ malfunction were present with equal frequencies in each group. The duration of antibiotic treatment averaged 8 1/2 days, and the average length of postoperative hospitalization was 29 days. Study antibiotics were changed for bacteriologic reasons in 11 patients taking clindamycin-gentamicin and 12 patients taking chloramphenicol-gentamicin (25% of the total), and two patients in the clindamycin-gentamicin group had a minor adverse reaction. Initial satisfactory clinical responses were obtained in 59 (63%) patients. Twenty-five patients (27%) subsequently developed unsatisfactory courses, but 48 (52%) patients remained well through the 30-day period. Septic-related mortality occurred in 18 (19%) patients, and two (2%) patients had unrelated deaths. There were no significant differences between the study regimens by the outcome criteria evaluated.

Pain control during the intensive care phase of burn care.

Pain management in burned patients is a controversial topic. Early effective pain management in these patients requires that the physician and nurse be aware of the advantages and disadvantages of various pharmacologic and nonpharmacologic measures that may be used. Newer approaches to assessing and managing pain in these patients must be explored.

Improved treatment of the Stevens-Johnson syndrome.

The Stevens-Johnson syndrome (SJS), a disease resulting in greater than 30% body surface area epidermal and mucosal desquamation, is reported to have a mortality of greater than 50%. Recommended treatment has included steroids, prophylactic antibiotics, nutritional support, and application of topical antibacterials. Since the lesions represent only epidermal loss without dermal necrosis, rapid reepithelialization should occur if the dermis is protected from desiccation with a biological dressing. Five nonburned patients with severe SJS were treated in the University of Washington burn center, Seattle, with urgent operative debridement of their wounds and application of porcine xenograft immediately after admission. Steroid administration was stopped. Antibiotics were used only for culture-proved infections. All patients completely re-epithelialized within a mean of 18 days. There was one death, a 9-year-old boy who was completely re-epithelialized when sudden fatal sepsis that originated from a ventriculovenous shunt placed when he was an infant developed. In this group of patients, rapid wound closure with xenograft and supportive care permitted rapid reepithelialization and decreased mortality and morbidity.

Burn depth estimation--man or machine.

A Burn Depth Indicator, utilizing reflectance ratios of red, green, and infrared light, has been devised and clinically tested for 18 months at our Burn Center. Using the endpoint of wound healing in less than or more than 3 weeks, clinical assessment by two experienced surgeons of intermediate depth wounds was compared to readings from the BDI . In about one third of cases the surgeons were unwilling to commit themselves to a prediction. In the cases where the surgeons were willing to make a prediction, they were incorrect about 25% of the time. The BDI was significantly more accurate than the clinical assessment in those predicted not to heal by the surgeons and maintained an accuracy of 79% in the wounds where the surgeons would not make a prediction. The BDI is portable, noninvasive, and provides an immediate reading. It may have utility as a triage tool for emergency rooms or combat situations, and has utility at present in our Burn Center as a more accurate tool than our clinical judgment in predicting which wounds should be excised and grafted during the first few days after injury.

Early excision and grafting vs. nonoperative treatment of burns of indeterminant depth: a randomized prospective study.

Compared to nonoperative treatment with silver sulfadiazine cream, early excision and grafting of 22 patients with indeterminant burns of less than 20% TBSA resulted in an average shorter hospitalization, lower cost, and less time away from work than 25 patients treated nonoperatively. While early excision and grafting resulted in increased use of blood products and operating room facilities, this did not result in increased patient morbidity. Long-term followup demonstrated no difference in need for reconstruction, incidence of blisters, incidence of loss of motion, or contour irregularities. Those patients treated nonoperatively required more late grafts for closure and demonstrated more hypertrophic scarring. Those treated by early excision demonstrated more mesh graft irregularity. We conclude that in otherwise healthy patients with dermal burns of indeterminant depth less than 20% total body surface area, early excision and grafting is the preferred form of treatment.

Factors affecting pain in burned patients--a preliminary report.

Twenty-six patients in a burn unit were given the McGill Pain Questionnaire, Illness Behaviour Questionnaire, State-Trait Anxiety Inventory, Zung self-rating depression questionnaire and visual graphic rating scales of pain, depression and helplessness. Preliminary results indicate significant pain and anxiety related to procedures such as debridement, physiotherapy and skin-grafting. Depression occurred in one third of patients and was associated with prolonged stay in hospital and complicated surgical course. The instruments used in this study are suitable for assessing pain and factors affecting it.

Early surgical excision versus conventional therapy in patients with 20 to 40 percent burns. A comparative study.

Using the records of 72 patients treated at the University of Washington Burn Center, this study compared the results of early surgical excision (by 14 days postburn) and autografting to those of autografting after spontaneous separation and bedside debridement of burn eschar. Excised patients had shorter hospitalizations and lower rates of burn wound sepsis and serious burn wound contamination, and less use of potentially toxic antibiotics (p less than 0.05) than did the prognostically equivalent group treated before the introduction of early excision. Excised patients required more blood transfusions (p less than 0.05), but did not differ significantly from controls in rates of mortality or other inpatient complications, in the number of operations performed, or in the adjusted hospital costs. Evaluation of patients treated over the entire study period for more shallow burns indicated no concurrent change in other aspects of burn care which might account for the observed results. We conclude that early excision and grafting in young, otherwise healthy patients with 20 to 40 percent total body surface area burns that are likely to heal within 3 weeks is more effective than the more traditional management of slow wound separation and debridement.

A prospective study of prophylactic penicillin in acutely burned hospitalized patients.

The use of prophylactic low-dose penicillin acutely burned, hospitalized patients remains controversial. Fifty-one adult patients with burns of 1% to 91% total body surface area were prospectively studied to determine the efficacy of prophylactic penicillin in the prevention of wound cellulitis and burn wound sepsis, and to examine the influence of prophylactic penicillin on the emergence of antibiotic resistant microorganisms. In 25 patients given a 5-day course of penicillin prophylactically, 11 developed cellulitis and two had burn wound sepsis. A similar group of patients given placebo developed seven cases of cellulitis and three cases of burn wound sepsis (p = 0.340). No patient in either group developed gentamicin-resistant Gram-negative organisms, although the gastrointestinal tracts of two patients in the penicillin group showed new colonization by yeast. We conclude that the routine administration of prophylactic penicillin neither protects against cellulitis and burn wound sepsis, nor promotes selection of antibiotic-resistant bacteria in hospitalized patients with acute thermal injury.
