Visceral injuries, wound infection and sepsis following electrical injuries.

Visceral injuries, wound infection and sepsis were investigated in 226 inpatients who sustained electrical burns over a period of 15 years. Four patients who sustained thoracic and abdominal organ injuries were noted in this series. The patients had injuries of the small intestine, stomach, colon and the lung. All the patients received operative treatment. Two of them died of sepsis. Injuries to the internal organs should always be considered following high-voltage injuries, and they should be managed as early as possible. The data concerning wound infection and sepsis following electrical injuries were evaluated in three consecutive 5-year periods. Over this period of 15 years, different antibiotic regimens were used for prophylaxis and treatment. Most patients in the current series had been contaminated or infected by various pathogens prior to admission. Long-lasting administration of prophylactic antibiotics in these patients showed no improvement in controlling the sepsis. After 1987, most of the microorganisms were eliminated following more effective antimicrobial therapy. The progressive decrease in infection frequency of species such as Pseudomonas aeruginosa, Proteus mirabilis and Enterobacter cloacae, appeared to be causally related to the changes in the general therapeutic protocol which included new antibiotics. The infections caused by E. coli and Staphylococcus aureus showed a rather steady state. A marked increase in frequency of negative wound cultures was also noted between the years 1989 and 1993. A gradual decrease in mortality rates was observed from the first to the last 5-year period, whereas mortality rates due to sepsis showed a gradual but slower decline. Sepsis (142 patients comprising 62.8 per cent of the total mortality rate) was the most frequent complication resulting in death.

Severe electrical injury.

From January 1979 to January 1987, 125 patients were treated in our Centre for various electrical injuries. Among them, 85 patients were over 15 years of age (89.4 per cent were males and 10.6 per cent females) and 40 patients were below 15 years of age (92.5 per cent were males and 7.5 per cent females). Electricians were the most frequently injured in the over 15-year-old age-group, whereas most patients under 15 years old were students. We focused our study on five patients with multiple and severe electrical injury. Two of these patients were injured while erecting TV aerials, two were injured at work and the other one was working on a house roof. Despite all our efforts extensive limb amputations were required. Following complete healing, we fitted prostheses to the amputation stumps. All the patients have now returned to society as capable individuals, two of them to their previous occupations and the other three with new occupations. Our experience with five patients showed that patients with severe electrical injury and multiple amputations have a reasonable chance of recovery. Rehabilitation therapy must be given as early as possible after the electrical injury so that the patients may return to their normal place in society.

Epidemiology of adults' and childrens' burns in a Turkish burn center.

From 1 January 1979 to 1 January 1985, 4094 patients were treated for burn injury in our centre. Of these, 84.9 per cent were treated as outpatients and 617 (15.1 per cent) were hospitalized. Of the 617 patients, 56.7 per cent were under 15 years of age (birth to 6 years: 67.7 per cent; 7-15 years, 32.3 per cent) and 43.3 per cent were over 15 years. The causes of burns in the over 15 years group were: flame, 36.3 per cent; electrical, 28.0 per cent; scalding, 18.4 per cent; liquefied petroleum (LP) gas explosion, 11.0 per cent; and others, 6.3 per cent. The burn cases in the under 15 years group were: scalding, 58.0 per cent; flame, 24.6 per cent; electrical, 10.0 per cent; hot meals, 5.2 per cent; and others, 2.0 per cent. After being resuscitated, these patients were treated with systemic antibiotics, local chemotherapy and silver-nitrate-incorporated amniotic membrane. Despite all medical efforts, 217 (35.7 per cent) of the hospitalized patients died as a result of various complications. At the same time, 3477 patients were treated as outpatients: 72.0 per cent of these were under 15 years old (birth to 6 years, 82.9 per cent, 7-15 years, 18.8 per cent) and 28.0 per cent patients were over 15 years of age. The causes of burn injury in these patients were: hot liquids, 61.7 per cent; flame, 17.0 per cent; hot meals, 8.4 per cent; hot metal, 5.8 per cent; electrical, 3.6 per cent; and chemical, 1.7 per cent.

The use of silver nitrate-incorporated amniotic membrane as a temporary dressing.

Human amniotic membrane is one of the most effective biological dressings used in burn treatment. Since 1978, we have been using human amniotic membrane incorporating 0.5 per cent silver nitrate. Studies in 96 patients using this method showed that the silver-incorporated membranes gave a better therapeutic effect than plain amniotic membranes. It was noted that 0.5 per cent silver nitrate incorporated into the membranes increased their manageability, provided easier application to the burned area and created a bactericidal effect, therefore reducing the risk of contamination and infection. One of the main advantages of wound coverage with amniotic membrane is that it does not appear to discourage re-epithelization, reduces fluid, protein, heat and energy loss, increases mobility and most important this may be the ideal wound cover next to the patient's own skin. Therefore, we highly recommend the use of 0.5 per cent silver nitrate-incorporated amniotic membrane, since it is readily available and freely obtainable, has low preparation and storage costs that make it an ideal dressing to use, especially in countries where economic factors prevent the purchase of other types of dressings.

Living unrelated donor kidney transplantation between spouses.

From November 3, 1975 to November 3, 1990, 874 kidney transplants were performed at out centers. Of these, 675 (77.2%) were from living donors and 199 (22.8%) were from cadaver donors. Five hundred eighty (66.4%) of the living donors were first degree related while 99 (11.3%) were unrelated or second degree related donors, 29 of which were spouses. All donor recipient pairs were ABO-compatible, with the exception of one pair. Donor recipient relations were wife to husband in 25 cases and husband to wife in 4 cases. All were first grafts and started functioning during surgery. In this series, the follow-up for the recipients was 4 to 64 months (mean 33.5 +/- 4.5 months). One-year patient survival and graft survival rates were 92.4% and 81.9%, respectively. Two-year patient survival and graft survival rates were 92.4% and 78.2%, respectively. The single ABO-incompatible case is also doing well, 21 months postoperatively. This study demonstrates that the interspouse kidney transplantation may be used when cadaver organ shortage is a problem. While providing the couple with a better quality of life, interspouse kidney transplantation also enables the couple to share the joy of giving and receiving the "gift of life" from one another.

Missed malignancies during laparoscopic cholecystectomy.

BACKGROUND/AIMS: Laparoscopic cholecystectomy is now the treatment of choice for symptomatic gallstone diseases. However, besides its great benefits, perhaps the most disappointing complication of this operation is missed malignancies. In this study, patients who had missed malignancies that were diagnosed shortly after laparoscopic cholecystectomy were studied. We aim to find out the cause of missed and delayed diagnosis. METHODOLOGY: Between 1991 and June 1997, 9 patients undergoing laparoscopic cholecystectomy, which had been performed elsewhere 2-9 months earlier, and having had missed malignancy were included in this study. A diagnostic survey was collected from the medical records, questionnaires, and a semiological analysis. All laboratory data and physical findings, before and after laparoscopic cholecystectomy, were recorded. Follow-up data were obtained through a telephone questionnaire. RESULTS: Of these 9 patients, 6 had colorectal carcinoma and 3 had pancreas carcinoma. All patients complained of recent atypical pain at the time of laparoscopic cholecystectomy, except for 1 patient who had no symptomatic regression. CONCLUSIONS: It is necessary to make a careful semiological, physical and laboratory analysis of patients with cholelithiasis before especially laparoscopic cholecystectomy. Elderly patients, atypical biliary pain and associated symptoms must draw attention to the possibility malignancy.

Diffuse cavernous rectal hemangioma--clinical appearance, diagnostic modalities and sphincter saving approach to therapy: report of 2 and a collective review of 79 cases.

Two cases of diffuse cavernous haemangioma of the rectum are reported and a thorough review of the world literature with a sum of 79 patients is done. We advocate low anterior resections for the treatment of this disease; sleeve resections are not necessary, since the recurrent bleeding and complication rates are not statistically different from the low anterior resections without mucosal stripping.
