Non-tumorous pathological changes in C57BL/6 CrSlc mice, which were reared under a barrier system and died spontaneously, were examined. At 3 months intervals 125 to 209 mice were purchased at 4 weeks of age and raised for the supply of aged animals. A large portion of the mice were used for various experiments between 3 and 30 months of age, while not a small number died spontaneously and were autopsied. The major non-neoplastic lesion was amyloidosis, with incidence of 55.5% and 74.4% for the autopsied female and male, respectively. The organs involved were the liver, kidneys, spleen, adrenal glands, ileum, heart and lungs. Skin ulceration and its scar, cerebral vascular calcification, glomerulosclerosis and sepsis in both sexes, distension of the seminal vesicles in males, fibroblast growth of the adrenal glands in females were commonly found. Incidence of spontaneous neoplastic lesions was 69.7% and 55.1% for the female and male, respectively.

The problem of skin ulcers in elderly surgical patients in critical care units is a serious one. Patients with skin ulcers suffer from pain, disfigurement, immobility, septicemia, and sometimes death. Critical care nurses can provide preventive techniques by understanding the complex relationship among the variables causing skin ulcers in elderly patients. The authors describe the variables most related to skin ulcers in elderly surgical patients.

A survey was made of the phage-types of staphylococci responsible for cross-infection in a large veterans' hospital between 1961 and 1964. An earlier survey had shown that in 1959 most of the infections were caused by staphylocci of the "80/81/82" group. In 1961 a new group of staphylococci were first recognized and provisionally designated as "Atypical Group III" strains; these were non-typable by the usual typing phages but showed inhibition patterns with some of the Group III phages. The "Atypical Group III" staphylococci all showed one or other of four patterns of multiple antibiotic resistance. By 1963 these resistant "Atypical Group III" staphylococci had become more frequent than "80/81/82" strains as causative agents of cross-infection, although both groups have continued to cause infections in the hospital. "Atypical Group III" strains mainly infected surgical wounds and skin ulcers, whereas "80/81/82" strains commonly produced primary skin sepsis, such as boils.

From 1976 to 1981, 25 cases of S. pyogenes septicemia were diagnosed at the University Medical Center, Lausanne, Switzerland, in 5 children and 20 adults. The twenty adult patients are described. The age range was from 24 to 94 years. The portal of entry was the skin (erysipelas, skin ulcers, surgical wounds) in 12 cases, the respiratory tract (upper 3, lower 3) in 6 cases, and the vagina in 2 cases. All except 3 patients were acutely ill with high temperature (39 degrees C) and toxic appearance. None had an underlying malignancy. The clinical course was complicated in 5 patients, i.e. septic arthritis (2), pulmonary abscess (1), endocarditis (1) and acute rheumatic fever (1). After initiation of penicillin therapy, temperature and symptoms resolved only slowly (mean 11 days). Four patients died from infection. In 2 of them the antibiotic treatment had been delayed. When a patient exhibits clinical signs of septicemia and muco-cutaneous lesions suggestive of a portal of entry, S. pyogenes septicemia should be suspected. Complications are frequent and the prognosis remains poor despite early adequate antibiotic treatment.

Capnocytophaga canimorsus is a fastidious, slow-growing, gram-negative, rod-shaped bacterium that belongs to the normal oral flora of dogs and cats. Human septicemic infections are associated with a high mortality; most cases occur in immunocompromised patients with a history of dog bite. The fifth case of cat-associated septicemia caused by Capnocytophaga canimorsus is described. The six case reports presented here point out the characteristics reported previously: (a) cats are a source of human infection; (b) alcohol abuse is an important risk factor for the development of septicemic Capnocytophaga canimorsus infection; (c) septicemic infection often manifests with disseminated intravascular consumption coagulopathy or purpura; and (d) some cases of septicemia in humans result from pets that lick skin ulcers.

1. Pressure ulcer formation is a major health care concern when one considers the costs involved and patient morbidity and mortality. Patients with skin ulcers experience pain, disfigurement, immobility, septicemia, longer hospitalizations, and sometimes death. 2. Pressure ulcers are one of the most common iatrogenic illnesses in health care that affect special patient populations--the elderly and the immobile. 3. Both cost and improvement in the patient's quality of life are important concerns in the implementation of improved prevention activities.

Pressure, moisture, shear forces and friction lead to skin ulcer formation. Nursing home and home-bound patients with restricted mobility, poor nutrition, incontinence and chronic conditions such as anemia, diabetes and dementia are at risk for ulcer formation. Bedridden patients should be turned from side to side at 30-degree angles at least every two hours. Mattress and chair cushions, splints and cradle boots may reduce pressure. Good hygiene and barrier ointments, condom catheters, absorptive products and scheduled toileting for incontinence may control moisture. Calorie and protein supplements, feeding assistance and serial weight measurements are essential in the management of malnourished patients. Treatment should be based on the stage of the ulcer and the presence of conditions such as necrotic debris, infection and drainage. Saline wet-to-dry dressings and enzymatic and surgical debridement are necessary to remove necrotic tissue. Saline-soaked gauze, hydrogel preparations and occlusive dressings provide the physiologic environment for fibroblasts to grow and form granulation tissue. Patients with sepsis may require hospital admission for both further evaluation and systemic antibiotic therapy.

In rodents calorie restriction (CR) reduces cancer incidence, improves health by delaying age-related declines in physiologic measures, and extends both median and maximal life span. The mechanisms underlying the various beneficial effects of CR remain undefined. In this study, heterozygous p53-deficient (p53(+/-)) mice (in which the inactivation of one allele of the p53 tumor suppressor gene increases susceptibility to spontaneous and carcinogen-induced tumor development) and wild-type (WT) litter mates were subjected to a two-stage skin carcinogenesis protocol with 7,12-dimethylbenz[a]anthracene and 12-O-tetradecanoylphorbol-13-acetate. Instead of skin carcinomas, however, the chemical treatment protocol caused ulcerous skin lesions, and 89% of mice fed ad libitum died from infection/septicemia. When WT mice were restricted to 60% of the average calorie intake of the respective ad libitum group, however, only 33% developed such lesions, and the CR mice survived twice as long on average as the ad libitum mice. CR also extended life span in p53(+/-) mice, but 50% of p53(+/-) mice subjected to CR still developed skin ulcers and mean life span was shorter than that seen in WT mice. Differences in response to CR between WT and p53(+/-) mice may be due to the reduction in p53 gene dosage, dissimilarity in the application of the CR treatment, or both. These results suggest that some of the beneficial effects of CR may need full expression of p53 for complete realization.

We present a patient with a cutaneous T-cell lymphoma/mycosis fungoides (CTCL/MF) followed for more than 10 years. After several different aggressive treatments to control progression of CTCL/MF, the patient developed several ulcerated tumors on the abdomen and limbs. Specific systemic antibiotic therapy failed to treat skin infection. While treating the stage III CTCL with polychemotherapy, we used an active colloidal hydrogel topically to manage wound healing and to treat and prevent potential sources of sepsis. After 11 weeks of treatment we observed complete cicatrization of ulcerated tumors. We reported on this case to describe the importance of a correct management of skin ulcers in immunosuppressed patients in order to avoid possible systemic spread of infection which represents the major cause of death in these patients.

A 52-year-old woman was admitted with complaints of nonhealing skin ulcers. The laboratory assessment showed a calcium level of 13.2 mg/dL (normal 8.4-10.2 mg/dL), albumin 2 g/dL (normal 3.5-4.8 g/dL), corrected calcium 14.8 mg/dL, phosphorus 1.4 mg/dL (normal 2.4-4.7 mg/dL), creatinine 0.7 mg/dL (normal 0.5-1.2 mg/dL), parathyroid hormone 893.3 pg/mL (normal 11.1-79.5 pg/mL). A technetium-sestamibi scan showed a left inferior parathyroid adenoma. The patient underwent a parathyroidectomy. Pathology showed a parathyroid adenoma. Despite treatment of her skin wounds with broad spectrum antibiotics and local wound care, the patient died of overwhelming sepsis. Calciphylaxis is a rare but serious disorder that leads to skin and soft tissue necrosis and requires prompt diagnosis and management.
