    Notes: Lathyrism is characterized by defective collagen synthesis due to inhibition of lysyl oxidase, an enzyme essential for interfibrillar cross-linking. The lathyritic agent β-aminoproprionitrile (β-APN) is considered an appropriate agent for studying connective tissue metabolism. We investigated the effects of ascorbic acid on collagen structure and serum cytokine levels in experimentally induced lathyrism. Forty Wistar rats weighing 200–300 g were used in the study: three test groups of 10 rats each (groups 2, 3 and 4) and 10 rats used as a control group (group 1). Experimental lathyrism was induced with daily subcutaneous injections of β-APN in the test groups for 40 days. On the 40th day, skin biopsies were taken from the control group (group 1) and group 2, to evaluate the effect of β-APN on dermal collagen. After the 40th day, 10 rats received ascorbic acid 100 mg/kg intraperitoneally daily for 15 days (group 3) and 10 rats (group 4) received no medication and served as a control for group 3. On the 55th day, skin biopsies were taken from groups 3 and 4. Serum concentrations of interleukin-6 and tumour necrosis factor-α were assessed in each group by enzyme-linked immunosorbent assay. Ultrastructural examination of the skin biopsies in group 1 revealed normal-appearing epidermal and dermal structures. Group 2 showed disorganization of the epidermis and collagen structure, and vacuolization of the endoplasmic reticulum in fibroblasts. In group 3, ultrastructural examination revealed significant improvement in the structure of dermal collagen after administration of ascorbic acid, whereas the changes in group 4 were unremarkable. Ascorbic acid administration significantly decreased the concentrations of serum cytokines in group 3 compared with group 2 (P 〈 0.001). Ascorbic acid administration significantly improved dermal collagen structure and serum cytokine levels in experimental lathyrism.

    Notes: Over-expression of bcl-2 in lymphocytes has an important role in some immunological and inflammatory diseases. Fas (CD95) is a cell surface molecule that mediates receptor-triggered apoptosis in various cells including autoreactive T cells. In this study we investigated bcl-2 and Fas (CD95) expression in dermal lymphocytes in active skin lesions of Behçet's disease (BD) and in skin biopsy samples with chronic, non-specific inflammations. Tissue sections of 29 skin lesions of Behçet's disease and of 10 chronic non-spesific inflammatory process cases from the archives of the Ondokuz Mayıs University's Pathology Department were immunohistochemically stained for bcl-2 and Fas (CD95), and lymphocytes in the dermal infiltrate were evaluated for cytoplasmic staining. bcl-2 staining was observed in the skin lesions of 22 cases (75.8%) of Behçet's disease. bcl-2 staining was detected in two (20%) control skin biopsy samples with non-specific chronic inflammation. Fas (CD95) positivity was not detected in lymphocytes in Behçet's disease-related skin lesions. Fas (CD95) staining was observed in only three skin biopsy samples with non-specific chronic inflammation. bcl-2 and Fas (CD95) staining values in Behçet's and non-specific inflammation groups were significantly different (P 〈 0.01); differences in the bcl-2 staining values between Behçet's patients with mucocutaneous involvement only and mucocutaneous and other systemic involvements were not significant (P 〉 0.05). Expression of bcl-2 and loss of Fas (CD95) expression in dermal lymphocytes may play a role in the development of skin lesions and may account for the chronic course with periodic exacerbations in BD.

    Notes: Background: Tumors can metastasize to the jaws, oral soft tissues, or salivary glands. Metastasis from distant organs and tissues to the jaws or oral cavity is considered rare.Results: The mandible is the most common site of metastasis of the oral and maxillofacial region. Radiographically, there is usually an area of radiolucency with hazy outline. Such lesions are manifested as radiopaque or sclerotic areas.Conclusions: Radiographic view of a tumor in the present case mimicked a periodontal lesion with an osteolytic area around the roots.

    Notes: Bcl-2 overexpression in lymphocytes play an important part in immunological and inflammatory diseases. In the present study, we investigated the bcl-2 expression in dermal lymphocytes of psoriatic skin biopsy samples. From the archives of the Department of Pathology, Ondokuz Mayis University Medical School (Samsun, Turkey), tissue sections belonging to 28 psoriasis cases and 10 chronic non-specific inflammatory skin disease cases were immunohistochemically stained by bcl-2. Positive staining was semiquantitatively graded from 1+ to 4+. Of the 28 psoriasis cases 20 were found to express bcl-2. Our data suggest that bcl-2-mediated inflammation plays a part in the pathogenesis and recurrent character of psoriasis.

    Neutrophilic dermatosis of the dorsal hands in a farmer (2004)

    Notes: Neutrophilic dermatosis of the dorsal hands is a recently described disorder, which is similar to Sweet's syndrome. It is characterized by erythematous plaques, pustules and haemorrhagic bullae located solely on the dorsal surface of the hands. We describe a 57-year-old man with neutrophilic dermatosis of the dorsal hands that occurred following exposure to a chemical fertilizer. There are few cases reported in the literature regarding neutrophilic dermatosis and the aetiology remains unclear. For the present case, we propose that neutrophilic dermatosis of the dorsal hands might have been induced by the chemical fertilizer.

    Notes: Summary  Intra-operative cyst rupture is a catastrophic event in the intracranial hydatid cyst disease. Dissemination of the cyst contents may lead to severe anaphylactic reactions and an increased risk of recurrence.  Several scolicidal agents have been used to eradicate the infective scolices but recurrences occur and no solution has been evaluated for its adverse effects to the brain tissue. Being a specific scolocidal agent albendazole has been shown to be 100% scolicidal in vitro. In this study, we present the electrophysiological and histopathological effects of intracerebral 2% albendazole injection in the rat brain. Vascular, neuronal and glial as well as inflammatory changes were evaluated in order to detect any adverse pharmacological effects. Electrophysiological and most microscopic parameters showed no significant effects attributable to albendazole but in 25% of the albendazole group cerebral gliosis was detected whereas no gliosis was present in the control group. It is concluded that being a specific scolicidal agent albendazole offers an efficient alternative for ruptured cerebral hydatid disease, but the significance and clinical importance of the gliosis should be further investigated.
