The influence of progress in the treatment of severe burns on the quality of life

The problems related to burns treatment can be considered among the oldest and most passionating in history of medicine. Since the early forties amazing progresses have been done in the comprehension of the physiopathology of burns. The fast development of resuscitating techniques determined a remarkable reduction of mortality in the first phase; in a similar way through new concepts in the project and construction of intensive care facilities dedicated to burns, where patients can be isolated and a high standard of environmental control can be guaranteed, together with new topical and systemic antibacterial treatment protocols, a significant reduction of infectious complications has been achieved. Concerning surgical treatment early tangential excision and cultured epidermal grafts can be considered the cornerstones of burn therapy. Quality of life of burnt patients have been greatly ameliorated by these technical advances. Burn sequelae however remain the main concern of survivors because of the many controversial aspects of burn scar physiopathology and treatment. Along my career many endeavours I dedicated in this important research field. I will then report the results of most interesting clinical and experimental studies carried out in the last 30 years by our group in collaboration with basic researchers. All the work done in this domain enhance our hope that good results can really improve quality of life in burns: this is the goal for those who dedicated the whole life to relieve the suffering of these badly injured patients.     

Evaluation of glaucoma patients referred to a university clinic during one year

Infections by Aeromonas spp. are a rare cause of systemic infection in normal and immunocompromised hosts. We report the cases of two patients with acute non-lymphoblastic leukemia who developed septic shock by Aeromonas species with unusual soft-tissue complications. One patient who was undergoing consolidation chemotherapy developed septic shock by Aeromonas hydrophila with rhabdomyolysis and subsequent soft-tissue destruction consistent with myonecrosis. She recovered with combination antibiotic therapy and supportive care. The second patient developed neutropenia due to ganciclovir treatment for post-allogeneic transplant cytomegalovirus antigenemia. He developed a rapidly progressive septic shock due to Aeromonas sobria with rhabdomyolysis, multi-organ failure and bilateral lower limb myonecrosis, and died within 48 hours. The portal of entry was not identified in either case. These cases confirm the potentially aggressive nature of these bacteria in neutropenic cancer patients with an unusual tendency to produce muscular and soft-tissue destruction.     

Eprosartan does not affect the pharmacodynamics of warfarin

The purpose of this study was to conduct a retrospective analysis of the clinical spectrum, treatment and morbidity of the patients who have suffered high tension electrical injuries with current passage through their body (59 patients). Voltage, localization and surgical treatment seem to be the main factors influencing the lesion and the morbidity. The following points were considered: (1) Is there any relation between known factors such as voltage and the localization of the points of contact with the incidence and the type of complications and sequelae? (2) Do the observations show that wound management and the excision of dead tissues is the most adequate? From factors studied in our patients (voltage, point of entry and pathway of current, associated multiple trauma or flame burns, surgical treatment) we have found that the voltage does not have any influence on the severity of the wound nor on the percentage of sequelae (cataracts, limb amputation, neurologic complications). The current pathway, as well as its points of entry, does not show any relation with the presence of renal failure, cardiac arrhythmia and cataracts. A clear relationship between the point of entry of the current and the appearance of neurologic injury with presence of paralysis and permanent regional anaesthesia at the same level was observed. The presence of associated burns was not related to any other complications or sequelae. For those patients whose length of contact has been shorter we find a lower rate of amputations despite having associated limb fractures. Fasciotomy incisions appear to confer benefit as this series shows that this procedure decreases the rate of limb amputations.     

Control of carboplatin-induced emesis with a fixed low dose of granisetron (0.5 mg) plus dexamethasone

The indications, advantages, complications, and benefits of peripheral neurectomy in patients with trigeminal neuralgia were studied in detail in 40 patients treated between 1982 and 1991. Twenty-eight patients had previously received radiofrequency thermocoagulation: peripheral neurectomy was performed for pain recurrence. These patients had excellent or good pain relief for at least 5 years postsurgery. Of the 12 patients who had peripheral neurectomy as their only procedure, seven had an excellent result and five had a good result. Five of the patients had recurrence of pain after 2 years but responded well to a second neurectomy. Elderly patients who experienced pain in the first and second divisions of the trigeminal distributions were the best candidates. Peripheral neurectomy is an effective, safe procedure for elderly patients who suffer from trigeminal neuralgia and have a limited life span.     

Complications of pyloromyotomy for infantile hypertrophic pyloric stenosis

BACKGROUND: Few references exist regarding contemporary complications of pyloromyotomy (PM) for infantile hypertrophic pyloric stenosis (IHPS). Therefore, we reviewed the frequency and outcome of patients with IHPS who developed complications from PM. METHOD: A 25-year retrospective review was performed in two populations. The first group included all infants who had a PM for IHPS at two pediatric surgery centers. The second group included all infants referred from other institutions who developed complications following PM for IHPS. RESULTS: Between 1969 and 1994, 901 PMs were performed. Intraoperative complications occurred in 40 patients (4%), including 39 duodenal perforations and 1 difficult intubation requiring prolonged ventilation. No unrecognized duodenal perforations or incomplete PMs were found. Postoperative complications developed in 52 patients (6%). The wound infection rate was less than 1%. Postoperative vomiting occurred in 31 infants (3%). The mortality rate was 0.1%, with 1 death due to sepsis from delayed diagnosis of Hirschsprung's disease. During the same study period, 11 patients were referred from other hospitals for postoperative complications. Five had persistent vomiting treated successfully with expectant management. Six infants needed reoperation: 3 for persistent IHPS, 1 for gastric outlet obstruction, and 1 for small bowel obstruction secondary to adhesions; 1 required wound abscess drainage. CONCLUSION: Pyloromyotomy is not without complications. Duodenal perforation should be infrequent, but when it occurs, it can usually be readily recognized and treated with minimal morbidity. Postoperative vomiting can be managed nonoperatively, but if it persists longer than 5 days, radiologic evaluation should be performed. Incomplete PM is uncommon and should not occur. A second myotomy is needed when the diagnosis of incomplete myotomy is established. A single standard of care should be expected of all surgeons who perform PM for IHPS.     

Use of laser Doppler flowmetry for estimation of the depth of burns

The trend for treatment of deep second degree burns and third degree burns is toward early excision and skin grafting. The ability to predict burn depth accurately as early as possible is important for early excision and skin grafting. This study, prospectively evaluated the ability of laser Doppler flow measurements, obtained within 72 hours after burn injury, to predict the depth of burn wounds. A Periflux system 4001 laser Doppler flowmeter was used to measure the cutaneous microflow circulation of 100 selected points of burn wounds on 44 inpatients and of 1680 selected points on 120 volunteers from March of 1993 to February of 1994. The mean value of superficial second degree burns checked by laser Doppler was 194.6 perfusion units (PU). The value of deep second degree burns was 59.7 PU, and the value of third degree burns was 5.1 PU. The mean normal cutaneous blood flow of 120 volunteers (control group) was between 4 and 9 PU, except on the head, neck, hand, and foot. Blood flow of more than 100 PU correctly predicted (90.2 percent of cases) a superficial second degree burn. Blood flow between 100 and 10 PU correctly predicted (96.2 percent of cases) a deep second degree dermal burn. That of less than 10 PU correctly predicted (100 percent of cases) a third degree burn. There was also a significant correlation between initial flow measurements and the depth of burn wounds. We conclude that laser Doppler flow measurements performed early after burn injury are useful in predicting the depth of burn wounds. Laser Doppler flowmetry has the advantage of being easy to use and noninvasive and of providing immediate results for early determination of burn depth. Laser Doppler flowmetry is useful in selecting patients for early excision and grafting of burn wounds.     

Engineering polysaccharides for biosorption of heavy metals at oil/water interfaces

Self-inflicted burns are a regular source of admissions to burns units world wide. This study examines the characteristics and outcomes of those who deliberately burn themselves. The medical records of all patients admitted to the Royal Brisbane Hospital Burns Unit and identified as having suffered a self-inflicted burn between 1990 and 1995 were reviewed. The records of patients who doused themselves with flammable liquid between 1984 and 1995 were examined as a separate group. Of 1072 admissions there were 44 cases (4.1 per cent) of deliberately self-inflicted burns. Average age was 30 yr with an average total burn surface area (TBSA) of 30 per cent (range 1-98 per cent). Schizophrenia, depression and personality disorder were diagnosed in 71 per cent. Alcohol intoxication was common in the rest. Suicide attempters were almost all male and the majority (60 per cent) were diagnosed with a major psychiatric illness. Self-mutilators suffered much less serious burns and none died. Self-inflicted burns accounted for 24 per cent of burns admitted to the intensive care unit. Self-immolation with flammable liquid resulted in severe burns with a 45 per cent mortality. A number of differences was demonstrated between those patients who had attempted suicide and those who had deliberately burnt themselves without suicidal attempt. Self-immolators constitute a considerable proportion of major burns admitted to this unit.     

Inhalation burns: apropos of 198 cases. Incidence of laryngotracheal involvement

Inhalation burns and laryngotracheal involvement were studied in a retrospective series of 635 patients hospitalized for skin burns at the Center for Burn Treatment from January 1993 to January 1997. Inhalation burns were observed in 31.1% of the cases. Exclusive laryngeal involvement occurred in 19.6% of the inhalation burns. Both tracheobronchial and laryngeal burns were observed in 27.2%. Patients with inhalation burns also had facial burns (90.9%) and extensive (> 50%) or severe (UBS > 200) skin burns in 39.8% and 29.7% of the cases respectively. Mortality of skin burns was increased six-fold to 19.1% in patients who also had inhalation burns. Intubation was used alone in 60.1% and was followed by tracheotomy in 27.2%. The decision for tracheotomy was essentially based on the probable duration of ventilatory assistance. Tracheotomy was required in case of severe inhalation burns and the predictable duration of intubation was over 8 days. Laryngotracheal stenosis occurring after inhalation burns is complex and extensive, with great variability over time. Laryngotracheal calibration is indicated as first intention therapy.     

HMG CoA reductase inhibitors and diet in familial hypercholesterolaemia

We describe a patient who is a carrier of hemophilia B, who was unusual in that she had symptoms and abnormal hematologic findings. She became pregnant and desired to have chorionic villus sampling for fetal sex determination. This was performed without complication. Her pregnancy continued, and she was delivered of a normal female infant with no complications for mother or infant. We believe this to be the first report of chorionic villus sampling in a symptomatic carrier of hemophilia B.     

Gastrointestinal emergencies with marathon-type running: omental infarction with pancreatitis and liver failure with portal vein thrombosis

This paper reports two patients with catastrophic complications after marathon-type running not hitherto documented. The first, who collapsed with acute abdominal pains, was found at surgery to have infarction of the omentum and later, after a second laparotomy, acute oedematous pancreatitis. The second patient, who collapsed semi-comatose with hyperthermia, developed disseminated intravascular coagulation, rhabdomyolysis, renal shutdown and progressive hepatic failure. With regular dialysis, his condition stabilised but liver function continued to decline, associated with thrombosis of the portal vein. The spectrum of potentially life threatening disorders includes upper gastrointestinal bleeding, haemorrhagic colitis and rarely infarction of the bowel. The present two cases provide further support for ischaemia being a major contributor to the gastrointestinal catastrophes of marathon-type running.     

Obstetric implications of burns in pregnancy

Analysis of 50 patients with burns in pregnancy has allowed the objective consideration of obstetric implications. Patients in the second and third trimester of pregnancy with burns of greater than or equal to 50% should be delivered immediately as maternal death is otherwise certain and fetal survival rate is not improved by waiting. Vaginal delivery has always proved possible, even in the presence of perineal burns but caesarean section should be considered and may be preferred. Patients in the first trimester may survive with more extensive burns and possible reasons for this are discussed. Pregnancy testing on admission should be mandatory in burns of women of reproductive age. In patients with burns of less than 40% in the second and third trimesters, spasmolytics should be used to suppress spontaneous labour and to cover operations. Greater fetal maturity without worsening maternal prognosis can thus be achieved. Insufficient data exist to recommend this for burns of between 40 and 50%.     

A retrospective study of sexual life in women with acute myocardial infarction

Nitrofurazone (N), povidone-iodine (P), and silver sulfadiazine (S) were compared in the emergency department outpatient treatment of 84 patients suffering second degree burns over less than 15% (adults) or 5% (children) of their total body surface area. Indices of healing were percent of healing, degree of dryness, crust separation, eschar separation, tissue granulation, and wound pain. Statistical analysis indicates that healing in N-treated patients was superior to that in S-treated patients: tissue granulation began sooner, crusts separated more rapidly, wounds were dryer, and the amount of healing at two weeks was greater. Results in P-treated patients were equivalent to those in N-treated when cases with complications were excluded from analysis. Among patients with less serious burns, N-treated patients suffered less pain than S-treated, but there was no significant difference in pain between N and P or between P and S. In patients with more serious second-degree burns there was more pain with P than with N, but neither P nor N differed significantly from S in this regard.     

Quality of life issues: parenteral nutrition to small bowel transplantation--a review

Parenteral nutrition (PN) has given life to patients with chronic intestinal failure who would otherwise have died. Home parenteral nutrition has improved the quality of life for many children. However, morbidity from this therapy remains significant with complications of line sepsis, lack of venous access, hepatic dysfunction, and pulmonary embolism. These complications are common in younger children. Detailed discussion must take place with the family regarding risks and benefits of PN. In those children developing complications of PN, intestinal transplantation is a logical extension of treatment. Early referral of patients for assessment is vital because significant mortality occurs when liver disease is established. Time is needed to counsel families on the potential benefits and risks of this treatment, including the physical and emotional demands made on the child and family. Overall worldwide survival for isolated small bowel transplantation is currently 50% and for combined small bowel and liver transplantation 40%. Significant complications are rejection, sepsis, and lymphoproliferative disease. Postoperative management can be complex and prolonged; child and parents require a great deal of physical and emotional support. The burden of care for parents decreases significantly after the first year. Small bowel transplantation offers a realistic alternative to PN. The choice of treatments is influenced by expected quality of life, which is just beginning to be evaluated.     

Meningitis after combined spinal-extradural anaesthesia in obstetrics

We report two cases of meningitis which developed after combined spinal-extradural procedures for obstetric analgesia. The first case was thought to be caused by aseptic or chemical meningitis and the second was a case of bacterial meningitis in a patient who also received an extradural blood patch. It is important that meningitis is considered as a differential diagnosis in patients who present with headache after spinal anaesthesia and that antibiotic therapy is selected to cover unusual organisms.     

Species makeup and some characteristics of the physiology of the bacteria isolated in sugar manufacture

Nineteen pregnant women with burn areas ranging from 6 to 92% of the total body surface area were treated at the US Army Institute of Surgical Research between 1951 and 1974. A review of these cases led to the following observations and conclusions: 1) Pregnancy does not alter the maternal outcome after thermal injury. 2) Maternal survival is usually accompanied by fetal survival. 3) If the gravida's injury is lethal, the pregnancy will usually terminate spontaneously prior to her death. 4) Obstetric intervention is indicated only in the gravely ill woman whose complications (hypotension, hypoxia, or sepsis) jeopardize the life of the fetus. 5) A better understanding of the complications of major burns and the care available in modern burn units should improve the prognosis for burned pregnant patients.     

The noninfectious respiratory complications of infection with HIV

Infection with HIV was first recognized through a clustering of unusual respiratory infections. The lung has been a major target manifesting many of the infectious complications of the immunodeficiency. Noninfectious pulmonary complications in HIV-infected individuals are also common and have been recognized since the advent of the AIDS epidemic. Malignancies involving the respiratory system, specifically Kaposi's sarcoma and non-Hodgkin's lymphoma, are epidemiologically linked to infection with HIV. Although other cancers have been identified in patients with HIV, these malignancies have a relationship to HIV infection that is unknown. Nonetheless, all cancers in the HIV-infected individual appear to follow a very deadly course. Interstitial pneumonitis and an alveolitis are also seen in individuals infected with HIV. Their relationship to the virus is unknown but may involve the lung's immune response to HIV. Pneumothorax and bullous lung disease are the sequela of pulmonary infections in the HIV-infected host. Pulmonary hypertension has been reported in HIV-infected patients, and like the other noninfectious respiratory complications, the link between the disease process and HIV is unknown. Bronchiectasis is now commonly recognized in AIDS patients who have survived prolonged immunosuppression and infection. Bronchoscopists have accumulated a collection of endobronchial lesions uncommonly seen in non-HIV-related pulmonary consultation. In the following review, we discuss the epidemiology, pathology, pathogenesis, clinical features, diagnostic findings, prognosis, and therapeutic options available for each noninfectious pulmonary complication. As the life expectancy for HIV-infected patients increases, the incidence of noninfectious pulmonary complications will rise.     

Role of B.A. Petrov in foundation and development of free flap skin transplantation problem

The article reviews the history of development of free-flap skin transplantation and basic role of acad. B.A. Petrov who was the first to show the role of dermatom skin transplantation in vast granulating wounds as the only method saving the life of patients with severe burns. He also suggested to solve an actual problem--deficiency of resources of donor skin--by repeated excision of skin flaps from previously used donor sites and use of cadaver skin. Very important is ales the role of B.A. Petrov in development of such particular questions as the role of patient's condition, wound bed am microbial flora of the wound in survival of skin transplants. In aspect of historical relationships the perspective of new approach to treatment of deep burns by transplantation of ceratinocytes, cultivated outside the patient's organism is shown.     

Electric iron contact burns in an Australian paediatric population

Accidental burn injury is common among children. Contact burns are the second most frequent cause of burns in children and electric iron contact burns constitute a substantial proportion of this group. A prospective analysis of electric iron burns presenting from 1988 to 1991 was conducted. The 38 iron burns treated during this period represented 19% of contact burns treated. The mean age of injury was 19 months. The male to female ratio was 1.1:1 and 80% involved the upper limb. Twenty-five per cent required operation. All burns occurred in the child's own home with the majority (74%) occurring in the central living areas while the child was supervised (45%). The child was most likely to be injured by touching the iron directly or pulling the cord. A substantial number of burns occurred even after the iron was switched off. Education should be directed towards the caregivers of young children emphasizing the need to use and store irons in areas to which children do not have free access. Powerpoints should be placed so that children cannot reach the cord. Manufacturers should provide insulated pads in which to store the iron and a retracting cord to help prevent the cord being within a child's reach.     

Long-term outcomes and life satisfaction of adults who had pediatric spinal cord injuries

OBJECTIVE: To determine long-term outcomes and life satisfaction of adults who sustained pediatric spinal cord injury (SCI). DESIGN: Structured interview of adults who were 25 years or older who had pediatric SCI. SETTING: Community. PARTICIPANTS: A convenience sample of 46 patients from a total of 81 patients who received care in an SCI program: 1 refused participation, 4 died, and 30 were lost to follow-up. MAIN OUTCOME MEASURES: A structured questionnaire including physical, psychosocial, and medical information. The Craig Handicap Assessment and Reporting Technique and two measures of life satisfaction were also administered. RESULTS: Participants were 25 to 34 years old, mean 27 years. Thirty-two had tetraplegia and 14 had paraplegia. Thirty-one were men. Mean years of education was 14. Fifty-four percent were employed, 48% lived independently, and 15% were married. Life satisfaction was associated with education, income, satisfaction with employment, and social/recreation opportunities, and was inversely associated with some medical complications. Life satisfaction was not significantly associated with level of injury, age at injury, or duration of injury. CONCLUSIONS: Individuals who had pediatric SCI, much like adult-onset SCI, have the greatest opportunity for a satisfying adult life if rehabilitation emphasizes psychosocial factors such as education, employment, and long-term health management.     

Nutrition support in critical illness

Sepsis, shock, multiple trauma, and burns are often associated with altered metabolism characterized by severe catabolism, wasting of the lean body mass, immune dysfunction, and compromised wound healing. Nutrition support is one of the mainstays in the management of these critically ill patients and is aimed at minimizing these complications. The purpose of this article is to compare stress hypermetabolism and starvation metabolism, to review current recommendations for the provision of energy and substrate to the critically ill patient, and to review pertinent literature regarding enteral vs parenteral nutrition. Finally, this article will provide a brief overview of new and future therapies with emphasis on specific substrates and growth factors and the potential for their use in the critically ill patient.
