Chelonid herpesvirus (ChHV) infection in tortoises associated with stomatitis-rhinitis complex is a severe, mostly epizootic disease characterized by proliferative and diphtheroid-necrotizing glossitis, pharyngitis, rhinitis, and tracheitis, often occurring with pneumonia and encephalitis. The UL5 gene from a German ChHV isolate was used to generate a digoxigenin-labeled 307-base-pair DNA probe by polymerase chain reaction (PCR). ChHV DNA was detected in paraffin-embedded tissues of five naturally infected tortoises (two Afghan tortoises [Testudo horsfieldii], USA; two Hermann's tortoises [Testudo hermanni], Switzerland; one T. hermanni, Germany) by means of in situ hybridization (ISH) and PCR. Distribution of ChHV DNA exhibits many characteristics of alphaherpesvirus but also some characteristics of betaherpesvirus infections. The amino acid sequence of a portion of the ChHV UL5 homolog exhibited more than 50% similarity to alphaherpesvirus UL5 proteins. Nuclear hybridization signals were detected in epithelial cells of the lingual mucosa and glands. Furthermore, ChHV DNA was observed in tracheal epithelium, pneumocytes, hepatocytes, the renal tubular epithelium, cerebral glia cells and neurons, and intramural intestinal ganglia. ChHV DNA in endothelial cells of many organs underlines the systemic character of the disease. Importantly, ChHV DNA was detected by ISH in multiple tissues of tortoises originating from different geographic provenances. This indicates a high degree of conservation of the UL5 gene fragment among viruses prevalent in tortoises on different continents. With the described ISH, a molecular biological tool is available for rapid and specific diagnosis of ChHV infections and, more importantly, comparative pathogenetic studies of ChHV isolates from geographically unrelated regions.

Hydroxyurea is an antimetabolite agent used in the treatment of myeloproliferative disorders and sickle cell anaemia. Although hydroxyurea is relatively well tolerated, adverse effects often involve skin and mucous membrane during long-term therapy. A group of 510 patients affected by chronic myeloid leukaemia from 1977 to 1998 has been considered. Only 158 patients were treated with hydroxyurea and fulfilled inclusion/exclusion criteria of this study. A spectrum of severe cutaneous and mucosal changes (inflammatory and neoplastic) was seen in about 13% of patients (21 patients out of 158) and was studied in detail. Cutaneous and mucosal atrophy were observed in all 21 patients. Skin atrophy was often characterized by numerous telangiectases, especially on legs and on sun-exposed sites (16/21). Cutaneous, mucosal and nail hyperpigmentation was evident, albeit with variable extent, in 10 of the 21 patients. Severe stomatitis and glossitis with flattening of papillae were another common finding. Five patients, who received a particularly long treatment with hydroxyurea, developed squamous-cell neoplasms on sun-exposed sites (both squamous-cell carcinomas and keratoacanthomas). Acral changes were characteristic and constant, including acral erythema (21/21), dermatomyositis-like changes on the dorsa of hands (7/21), ulcers localized on acral areas of legs, on genitalia and oral mucosae (20/21). The frequency and the variety of these muco-cutaneous changes are reported and the mechanisms by which hydroxyurea may induce this muco-cutaneous syndrome-like group of changes, are proposed.

Glucagonomas are rare tumors. They are predominantly located in the body or tail of the pancreas and display a constellation of signs and symptoms referred to as glucagonoma syndrome. The term necrolytic migratory erythema is used to characterize the distinctive rash associated with this syndrome. This report describes a classic presentation consisting of dermatitis, glossitis, stomatitis, angular cheilitis, anemia, and weight loss that was associated with the finding of a pancreatic mass and a markedly elevated plasma glucagon level. After pancreatic resection, the patient had complete resolution of the rash and normalization of plasma glucagon.

Forty-one patients with oral lesions and symptoms were enrolled in the study. Their ages ranged from 16 to 79 years with a mean age of 48.5 years. They were divided into two groups. Group I consisted of 25 patients with oral lichen planus and group II consisted of 16 patients with stomatitis or glossitis. Their complete blood counts, hemoglobin typing, serum and red cell folate, and serum vitamin B12 levels were studied. The results revealed low red cell folate levels in 11 out of 25 patients (44%) in group I and 9 out of 16 patients (56%) in group II. The serum vitamin B12 levels were within normal range in both groups. They were defined as having folate deficiency (n = 10), folate deficient erythropoiesis (n = 3) and folate depletion (n = 7). None of them had anemia nor macrocytes. Therefore, folate levels should be investigated in patients with oral lesions and symptoms especially those with risk factors of age, poor nutrition or systemic diseases. When suspected, daily folic acid supplements should be given.

Fatal disseminated toxoplasmosis was diagnosed in a Risso's dolphin (Grampus griseus) dam and its fetus on the basis of pathologic findings, immunohistochemistry, and structure of the parasite. The dolphin was stranded alive on the Spanish Mediterranean coast and died a few hours later. At necropsy the dam was in good condition. From the standpoint of pathology, however, it had generalized lymphadenomegaly and splenomegaly, enlargement of and multifocal hemorrhage in the adrenal glands, diffuse mucosal hemorrhage of the glandular and pyloric stomach, ulcerative glossitis and stomatitis, focal erosions and reddening of the laryngeal appendix, and severe paraotic sinusitis with intralesional nematodes Crassicauda grampicola. The dolphin was pregnant, most probably in the first gestational trimester. The most prominent microscopic lesions were multifocal granulomatous encephalomyelitis, diffuse subacute interstitial pneumonia, mild multifocal necrotizing hepatitis and nonsuppurative cholangiohepatitis, gastritis and adrenalitis, mild lymphoid depletion, medullary sinus and follicular histyocitosis, and systemic hemosiderosis. The fetus had foci of coagulative and lytic necrosis in the kidneys, the lung, and the heart. Most lesions were associated with tachyzoites and tissue cysts of Toxoplasma gondii. The diagnosis was confirmed immunohistochemically. This is the first report on toxoplasmosis in a Risso's dolphin (G. griseus) and on transplacental transmission to an early-stage fetus in any cetaceans.

Pellagra is a nutritional wasting disease attributable to a combined deficiency of tryptophan and niacin (nicotinic acid). It is characterized clinically by four classic symptoms often referred to as the four Ds: diarrhea, dermatitis, dementia, and death. Prior to the development of these symptoms, other nonspecific symptoms insidiously manifest and mostly affect the dermatological, neuropsychiatric, and gastrointestinal systems. A review of the literature reveals several case reports describing pellagra in patients with anorexia nervosa. The most common features of pellagra in patients with anorexia nervosa are cutaneous manifestations such as erythema on sun-exposed areas, glossitis, and stomatitis. Health care providers might consider a trial of 150-500 mg niacin if anorexic patients exhibit these cutaneous findings. Pellagra can be diagnosed if cutaneous symptoms resolve within 24-48 hours after oral niacin administration. To further corroborate a diagnosis of pellagra in anorexic patients, specific 24-hour urine tests for niacin metabolites and 5-hydroxy-indole-acetic acid could be run prior to treatment with niacin being instituted. Other factors, such as mycotoxins, excessive dietary leucine intake (although not in anorexia), estrogens and progestogens, carcinoid syndrome, and various medications, might also lead to the development of pellagra. Although pellagra appears to be a rare, yet possible secondary complication of anorexia nervosa, it should be considered in the work-up of patients who exhibit cutaneous manifestations subsequent to sunlight exposure.

After 10 days of minocycline therapy, stomatitis, glossitis and esophagitis were seen in a 62-year-old male patient, who had previously tolerated minocycline for > 20 years without complications. This typical side effect of minocycline was initially misinterpreted in the differential diagnosis and was only diagnosed, when the patient was reexposed to a new 7-day minocycline therapy. Healing was achieved by termination of the minocycline therapy and the initiation of antimycotic treatment.

In September and October 2002, an epizootic of neurologic disease occurred at an alligator farm in Florida (USA). Three affected American alligators (Alligator mississippiensis) were euthanatized and necropsied, and results confirmed infection with West Nile virus (WNV). The most significant microscopic lesions were a moderate heterophilic to lymphoplasmacytic meningoencephalomyelitis, necrotizing hepatitis and splenitis, pancreatic necrosis, myocardial degeneration with necrosis, mild interstitial pneumonia, heterophilic necrotizing stomatitis, and glossitis. Immunohistochemistry identified WNV antigen, with the most intense staining in liver, pancreas, spleen, and brain. Virus isolation and RNA detection by reverse transcription-polymerase chain reaction confirmed WNV infection in plasma and tissue samples. Of the tissues, liver had the highest viral loads (maximum 10(8.9) plaque-forming units [PFU]/0.5 cm3), whereas brain and spinal cord had the lowest viral loads (maximum 10(6.6) PFU/0.5 cm3 each). Virus titers in plasma ranged from 10(3.6) to 10(6.5) PFU/ml, exceeding the threshold needed to infect Culex quinquefasciatus mosquitoes (10(5) PFU/ml). Thus, alligators may serve as a vertebrate amplifying host for WNV.

Oral manifestations of diabetes mellitus have been documented, but the effect of glycemic control on the oral tissues has been scantily reported. The oral health status of 65 metabolically controlled adult diabetic patients attending the Diabetes Clinic of Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Nigeria, was prospectively assessed over six months and compared with that of 54 non-diabetic acting as controls. The mean duration of diabetes was 100.5+/-85.1 months. The difference in periodontal status of the patients and control, assessed using the Community Periodontal Index of Treatment Needs (CPITN), was not statistically significant (p=0.07). The degree of hyposalivation between the two groups was, however, statiscally significant (p<0.05). No significant difference was observed in the altered taste, burning mouth sensation, angular cheilitis, glossitis, and stomatitis status of the two groups. We conclude, with adequate metabolic control, the oral health status of a diabetic may not be significantly different from that of a non-diabetic except for xerostomia. A good understanding of the interactions between systemic diseases and oral health is imperative for physicians and dental practitioners. The need for early detection and closer linkages between the dental and medical professions in managing diabetic patients is emphasized.

ChHV and Mycoplasma agassizii infections in tortoises share similar clinical signs of lethargy, anorexia, rhinitis, and conjunctivitis. In addition, ChHV infection is associated with glossitis and stomatitis and often causes high morbidity and mortality. As was seen in this case, ChHV infection tends to cause higher mortality in T hermanni compared with T graeca and T marginata. T horsfieldi is also considered highly susceptible to ChHV but appeared unaffected in this outbreak.
