Regional odontodysplasia of the deciduous and permanent teeth associated with eruption disorders : a case report

Regional odontodysplasia (RO) is an unusual, non-hereditary anomaly of the dental hard tissues with characteristic clinical, radiographic and histological findings. Clinically, RO affects the primary and permanent dentition in the maxilla and mandible or both jaws. Radiographically, there is a lack of contrast between the enamel dentin, both of which are less radiopaque than unaffected counterparts. Additionally, enamel and dentin layers are thin, giving the teeth a ?ghost-like? appearance. Histologically, areas of hypocalcified enamel are visible and enamel prisms appear irregular in direction. Coronal dentin is fibrous, consisting of clefts and a reduced number of dentinal tubules; radicular dentin is generally more normal in structure and calcification. The RO etiology is uncertain; numerous factors have been suggested and considered as local trauma, irradiation, hypophosphatasia, hypocalcemia, hyperpyrexia. The treatment of RO has given rise to controversy. These cases require a continuous and multidisciplinary approach. Most clinicians advocate extracting the affected teeth as soon as possible and inserting a prosthetic replacement. Other clinicians prefer restorative procedures, if possible, to protect the affected erupted teeth. A case of RO in an 8 year-old male whose chief complaint was the absence of eruption of permanent teeth is presented. Clinical, radiographic and histological findings are described

A Rare Cutaneous Adnexal Tumor: Malignant Proliferating Trichilemmal Tumor

Proliferating trichilemmal tumors (PTTs) are neoplasms derived from the outer root sheath of the hair follicle. These tumors, which commonly affect the scalp of elderly women, rarely demonstrate malignant transformation. Although invasion of the tumors into neighboring tissues and being accompanied with anaplasia and necrosis are accepted as findings of malignancy, histological features may not always be sufficient to identify these tumors. The clinical behavior of the tumor may be incompatible with its histological characteristics. Squamous-cell carcinoma should certainly be considered in differential diagnosis because of its similarity in morphological appearance with PTT. Immunostaining for CD34, P53, and Ki-67 is a useful adjuvant diagnostic method that can be used in differential diagnosis aside from morphological findings. In this study, we aimed to present the case of a 52-year-old female patient with clinicopathological features. We reported a low-grade malignant proliferating trichilemmal tumor in this patient and detected no relapse or metastasis in a 24-month period of follow-up

Agronomic characteristics of Serapias vomeracea (Burm. f.) Briq. salep orchids

Although salep orchids are annual plants, each new generation emerges larger than their parents. There are no data on the developmental performance of these species that cannot be cultivated due to production difficulties. This study discusses Salep vomeracea (Burm. f.) Briq., one of the most common species in temperate climate regions. Tubers obtained from natural flora were divided into seven groups according to their size. Morphological characteristics of the seedlings developed from these tubers were determined and observed up to the harvest stage. The study was carried out in a randomized plot design with three replications and for two years. As a result of statistical analysis, all parameters were found to be significant. The canonical correlation between the first pair of canonical variables was 0.995 (p<0.01). The data obtained from the length of the planted tuber made the biggest contribution to the explanatory power of the canonical variables. Additionally, the mathematical relationship between width, height and area values of salep leaves was determined

DETERMINATION OF GENETIC VARIABILITY OF EASTERN AND SOUTHEASTERN ANATOLIA REGION TOBACCOS

Tobacco establishing various ecotypes in different ecological zones is one of the crop plants having high genetic variability. In previous years, tobacco ecotypes were conserved by tobacco farming controlled governmentally. But now tobacco sector is privatized. As a result of privatization, companies in tobacco sector have adopted a few ecotypes based on tobacco farming. This phenomenon has increased the risk of extinction for the present genetic variability and now some cultivars are nearly extinct. In this study, conducted to prevent genetic resource erosion, different tobacco ecotypes were determined by visiting the tobacco fields in Eastern and Southeastern Anatolia Region. Some morphological, technique and yield characters of the cultivars were compared by farming them in field via seed. 12 characters of the cultivars were tabulated. Seeds of cultivars, characters of which were determined were delivered to Seed Gene Bank of Turkey

The Possible Efficacy of Artichoke in Fluconazole Related Hepatotoxicity

Although fluconazole related hepatotoxicity (FRH) is rare, mortal acute hepatic necrosis and jaundice were reported in immunocompromised states such as acquired immunodeficiency syndrome (AIDS) and bone marrow transplant (BMT). We present a case of a patient with multiple sclerosis who developed hepatotoxicity with the use of a single 150 mg fluconazole tablet for fungal vaginitis, 10 days after methylprednisolone pulse treatment. Our patient’s alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were decreased, 1200 U/L and 800 U/L, respectively, and bilirubin levels were consistent at 37 mg/dL. Artichoke which has anticholestatic and antioxidant properties was used by our patient. She consumed a 30 mg artichoke leaf extract tea 3 times a day. The bilirubin levels significantly declined at the end of the first week and all liver function tests were normalized within 2 months

Effects of Proton Pump Inhibitors and H2 Receptor Antagonists on the Ileum Motility

Objectives. To investigate the effects of proton pump inhibitors (PPIs) and H2 receptor antagonists on ileum motility in rats with peritonitis and compare changes with control group rats. Methods. Peritonitis was induced by cecal ligation and puncture in 8 rats. Another of 8 rats underwent a sham operation and were accepted as controls. Twenty-four hours later after the operation, the rats were killed, and their ileum smooth muscle was excised and placed in circular muscle direction in a 10 mL organ bath. Changes in amplitude and frequency of contractions were analyzed before and after PPIs and H2 receptor blockers. Results. PPI agents decreased the motility in a dose-dependent manner in ileum in both control and intraabdominal sepsis groups. While famotidine had no significant effect on ileum motility, ranitidine and nizatidine enhanced motility in ileum in both control and intraabdominal sepsis groups. This excitatory effect of H2 receptor antagonists and inhibitor effects of PPIs were significantly high in control group when compared to the peritonitis group. The inhibitor effect of pantoprazole on ileum motility was significantly higher than the other two PPI agents. Conclusions. It was concluded that H2 receptor antagonists may be more effective than PPIs for recovering the bowel motility in the intraabdominal sepsis situation

A Rare Renal Epithelial Tumor: Mucinous Cystadenocarcinoma Case Report and Review of the Literature

Primary renal mucinous cystadenocarcinoma is a very rare lesion of kidney which originates from the metaplasia of the renal pelvic uroepithelium. Only one case with primary mucinous cystadenocarcinoma has been reported in the English literature. We report second case of mucinous cystadenocarcinoma which was radiologically classified as type-IIF Bosniak cyst in peripheral localization. We aimed to present this extreme and unusual entity with its radiological, surgical, and pathologic aspects under the light of literature
