A newly recognized disease in dogs, ulcerative dermatosis associated with diabetes mellitus (diabetic dermatopathy), was diagnosed in 2 dogs with pancreatic endocrine tumors that had immunohistologic evidence of glucagon production. Dogs developed diabetes mellitus in the later stages of the illness, months after the skin disease was first observed. Liver disease was identified and characterized by high serum alkaline phosphatase and alanine transaminase activities. Clinically, erythema and crusting involved the footpads, the face, perioral and genital skin, and ventrum. Histologically, skin lesions were intercellular and intracellular edema and necrosis of the upper half of the epidermis and diffuse parakeratosis. Clinically and histologically, skin lesions closely resembled necrolytic migratory erythema of people, a skin disease that usually is associated with a glucagon-secreting pancreatic endocrine tumor and diabetes mellitus (glucagonoma syndrome): The morphologically descriptive term, superficial necrolytic dermatitis, was preferred over the previously proposed names hepatocutaneous syndrome and diabetic dermatopathy, which each connote only a single feature of the disease.

In order to objectively evaluate the efficacy and the safety of ceftriaxone (CTRX) using once daily administration of 1 g to cases of acute suppurative otitis media and acute exacerbation of chronic suppurative otitis media, a group comparison study by the envelope method was conducted using cefotiam (CTM) as the control drug (2 g twice daily). The results obtained are summarized as follows. 1. Clinical efficacies evaluated by the committee were 71% in the CTRX group and 86% in the CTM group for acute suppurative otitis media, and 63% and 60%, respectively, for chronic suppurative otitis media. When all cases were considered both groups evidenced a clinical efficacy of 64%, and no significant difference was observed between the 2 groups. 2. Clinical efficacies evaluated by the physician in charge were 65% in the CTRX group and 86% in the CTM group for acute suppurative otitis media, and 72% and 60%, respectively, for chronic suppurative otitis media. When all cases were considered efficacies were, respectively, 70% and 64%, showing no significant difference between the 2 groups. 3. Bacteriological efficacies were 88% in the CTRX group and 86% in the CTM group for acute suppurative otitis media, and 74% and 62%, respectively, for chronic suppurative otitis media. With all cases bacterial eradication rates were, respectively, 76% and 67%. Bacterial eradication rates were always higher for the CTRX group than for the CTM group, but the difference was not significant between the 2 groups. 4. Against infections caused by Staphylococcus aureus alone, CTRX showed equal clinical and bacteriological efficacies to CTM. 5. As side effects, dermatitis, vomiting, and malaise were observed in 5 cases (4%) of the CTRX group and 3 cases (3%) of the CTM group. As clinical testing abnormalities, elevations of GOT, GPT, and Al-P, and thrombocytopenia were noted only in 3 cases (5%) of the CTRX group. Furthermore, all of these abnormalities were temporary and of moderate degree or mild, thus the safety of either drug was considered high. 6. Clinical utilities were 71% in the CTRX group and 86% in the CTM group for acute suppurative otitis media, and 72% and 62%, respectively, for chronic suppurative otitis media. When all cases were included, they were 72% and 66%, respectively, and there was no significant difference between the 2 groups. It is concluded from the above results that CTRX is a highly useful drug with once daily administration of 1 g in the treatment of suppurative otitis media.

Examinations were performed of 31 fattened pigs suffering from papular dermatitis (PD) and 33 fattened pigs without dermal changes (C) coming from the D. large pig-fattening farm and the production breeding herd of pigs. The weight of the pigs was from 95 to 105 kg. Both farms are sited in a mining area (intensive lignite extraction). The PD pigs, compared with the controls (C), had less total protein, cholesterol and calcium in their blood serum and increased concentrations of thyroxine (T4), non-esterified fatty acids (NEFA), vitamins A and E, inorganic phosphorus and potassium, and the higher alanine aminotransferase (ALT) activity. The PD pigs also had an increased leucocyte count in blood. In their peripheral lymphocytes the PD pigs had a significantly higher number of aberrant cells, 3.9 times higher number of chromosome breaks, slightly increased rate of sister chromatid exchanges, but half the number of chromosome exchanges of the C pigs. No differences between PD pigs and the controls were recorded in the response of the T-lymphocytes of peripheral blood to non-specific phytohaemagglutinin stimulation; neither were there any substantial differences in the concentration of serum immunoglobulins of the IgG, IgM and IgA classes. The PD and C pigs of both herds (the D. and M. farms) had low concentrations of all three serum immunoglobulins. The higher occurrence of PD in the D. herd, compared with the M. farm, is associated with a greater reduction of serum immunoglobulins (IgM by 38%, IgA by 25%, IgG by 15%).

Health conditions were evaluated in 80 electrical workers exposed for many years to polychlorinated biphenyl (PCB) mixtures with a 42% mean chlorine content, who had blood PCB concentrations from 41 to 1319 micrograms/kg. The clinical study was based on personal history data, physical examination, and laboratory tests (red cell and leukocyte count; determination of haemoglobin, packed cell volume, bilirubin, serum protein electrophoretic fractions, pseudocholinesterase, AST, ALT, GGT, and OCT). Fifteen workers were found to have skin diseases--chloracne (4), folliculitis (4), oil dermatitis (1), juvenile acne (1), and dermatitis due to irritative or allergic agents (5). Sixteen workers showed more or less pronounced hepatic involvement, consisting most often of hepatomegaly with an increase in serum GGT, AST, ALT, and OCT values. In two workers bleeding cavernous haemangiomas were discovered, in one case associated with chronic myelocytic leukaemia. All the workers with chloracne were employed on electric capacitor impregnation with PCBs, and no definite association was found between chloracne and blood PCB concentrations. Conversely, a significant positive association was found between the abnormal liver findings and blood PCB concentrations, particularly trichlorobiphenyl blood concentrations. The abnormal hepatic findings observed are similar to those reported in experimental animals given PCBs, and in some workers such findings should probably be considered as clinical signs of hepatic microsomal enzyme induction.

Two dogs with metabolic epidermal necrosis had hyperkeratosis of the footpads accompanied by erythematous, erosive and crusting lesions affecting the muzzle, external genitalia, perineum and periocular regions. Histopathological examination of skin biopsies revealed a superficial hydropic dermatitis with marked parakeratosis. Both dogs had high plasma activities of alkaline phosphatase and alanine aminotransferase and high concentrations of glucose, and also a marked hypoaminoacidaemia. Despite these similarities, the cutaneous eruptions were associated with different underlying diseases. One dog had a pancreatic carcinoma which had metastasised widely; the primary tumour and the metastases showed glucagon immunoreactivity on immunocytochemical staining, and the dog's plasma glucagon concentration was markedly greater than that of control dogs. The other dog had diffuse hepatic disease; its plasma glucagon concentration was similar to that of control samples and cirrhosis was identified post mortem. Metabolic epidermal necrosis in dogs is a distinct cutaneous reaction pattern which may be associated with different underlying systemic diseases; however, the pathogenesis of the skin lesions remains unclear.

The U.S. Air Force is converting from JP-4 jet fuel to the less volatile JP-8 jet fuel, which is similar to commercial Jet Fuel A. Our previous 90-day inhalation study with JP-8 vapor, using F-344 rats and C57BL/6 mice, resulted in no treatment-related adverse effects other than alpha 2-microglobulin nephropathy in male rats (Mattie et al., 1991). In the present study, male rats were dosed with neat JP-8 (0, 750, 1500, 3000 mg/kg) daily by gavage for 90 days in an effort to characterize the kidney lesion and assess further any additional adverse effects associated with prolonged oral exposure to this fuel. Results of this study revealed a significant dose-dependent decrease in body weights of rats exposed to JP-8. Male rat-specific alpha 2-microglobulin nephropathy was observed by histopathologic examination. A number of significant changes were also seen in blood and urine that were not dose-dependent. Additional treatment-related effects were a gastritis and a perianal dermatitis. Although there were no histopathological or weight changes in the livers of exposed rats, there was an increase in the liver enzymes AST and ALT. The elevated enzymes did not increase with increasing dose of JP-8.

From 1984 through 1992, staff at The Marine Mammal Center (TMMC, Sausalito, California, USA) examined 207 northern elephant seals (Mirounga angustirostris) with a condition of unknown etiology called northern elephant seal skin disease (NESSD). The skin lesions were characterized by patchy to extensive alopecia and hyperpigmentation, punctate or coalescing epidermal ulceration, and occasionally, massive skin necrosis. Microscopic lesions included ulcerative dermatitis with hyperkeratosis, squamous metaplasia and atrophy of sebaceous glands. All diseased seals were less than 2 years of age and suffered from emaciation, depression, and dehydration. Mortality from septicemia increased significantly with severity of skin ulceration. Compared to 14 apparently unaffected seals, diseased seals had depressed levels of circulating thyroxine, triiodothyronine, retinol, serum iron, albumin, calcium, and cholesterol. Levels of alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, gamma glutamyl transpeptidase, blood urea nitrogen, and uric acid were elevated. Morphometrically, diseased animals were approximately 15% smaller than normal seals of the same sage. Serum and blubber concentrations of 36 polychlorinated biphenyl congeners (sigma PCB) and dichloro-diphenyl-dichloroethylene (p,p'-DDE) were negatively correlated with body mass. Mean concentrations of sigma PCB and p,p'-DDE in serum in diseased seals were elevated as compared to apparently normal seals. Etiology of this syndrome remains unknown, but the possibility of PCB toxicosis cannot be ruled out.

A 47-year-old woman visited a clinic with dyspnea which had continued for two months and was followed by general fatigue and fever. Antibiotics were not effective. Edematous erythema occurred on her face, elbows, knees and feet, and she entered our hospital. A skin biopsy revealed interface dermatitis with severe edema and mucinosis in dermis. Diffuse bilateral infiltration was observed in the chest X-ray, and laboratory findings showed increased LDH, GPT, GOT and CPK. No antinuclear factor was detected. Her respiratory condition rapidly worsened, and she died eight days after hospitalization in spite of corticosteroid pulse therapy. The autopsy revealed that the main cause of death was diffuse alveolar damage (DAD). Interstitial pneumonia related to dermatomyositis is not histologically uniform; the response to the therapy depends on its histological type. The patients with dermatomyositis who have poor prognosis are clinically characterized by acute onset with general symptoms and less pronounced muscle weakness; they generally show DAD in their lungs. We need to establish a simple method for distinguishing histological types of interstitial pneumonia and adequate therapy for each one.

Three red kangaroos (Megaleira rufus), an adult male, an adult female, and a yearling, were exposed in bedding and food to coastal bermuda hay that contained the toxic plant Lantana camara. The adult male exhibited signs of anorexia, depression, lethargy, and jaundice. The adult female was presented dead. After 1 wk, following exposure to sunlight, the adult male and a yearling joey developed exudative dermatitis of the ear margins, eyelids, muzzle, and scrotum and opacity of the corneas. The adult male had a leucocytosis, anemia, bilirubinemia, bilirubinuria, hyperproteinemia, and elevated alanine aminotransferase, gamma glutamyl transpeptidase, alkaline phosphatase, and bile acid serum levels. Postmortem examination of the adult male revealed jaundice, and the liver was swollen, mottled, and pale yellow to reddish yellow. The gall bladder was markedly distended. Histopathologically, there was hepatocellular enlargement with vesiculation of the nuclei and sporadic feathery degeneration of the cytoplasm. The yearling joey survived and was treated symptomatically with i.v. fluids and antibiotics. The history, clinical signs, diagnostic findings, necropsy findings, and exposure to the toxic plant Lantana camara support the diagnosis of secondary photosensitization and hepatoxicity.

Punicalagin and punicalin were isolated from the leaves of Terminalia catappa L., a Combretaceous plant distributed throughout tropical and subtropical beaches, which is used for the treatment of dermatitis and hepatitis. Our previous studies showed that both of these compounds exert antioxidative activity. In this study, the antihepatotoxic activity of punicalagin and punicalin on acetaminophen-induced toxicity in the rat liver was evaluated. After evaluating the changes of several biochemical functions in serum, the levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were increased by acetaminophen administration and reduced by punicalagin and punicalin. Histological changes around the hepatic central vein and oxidative damage induced by acetaminophen were also recovered by both compounds. The data show that both punicalagin and punicalin exert antihepatotoxic activity, but treatment with larger doses enhanced liver damage. These results suggest that even if punicalagin and punicalin have antioxidant activity at small doses, treatment with larger doses will possibly induce some cell toxicities.
