Child drowning deaths in Aydin province, western Turkey, 2002-2012.

INTRODUCTION: Drowning, a major public health problem worldwide, occurs as an accident, suicide, or homicide. Deaths with an accidental origin are common in childhood in the 0-18 age group. In our study, pediatric drowning cases for whom a postmortem examination and an autopsy were conducted by Adnan Menderes University Department of Forensic Medicine were evaluated. The characteristics were determined and compared with domestic and foreign studies. MATERIALS AND METHODS: A total of 39 cases in the 0-18 age group in Aydin between 2002 and 2012 were analyzed regarding age, gender, cause of death, origin, the accident scene, and the month in which the death occurred. RESULTS: Of the drowning cases, 33 (84.6 %) were male, and 6 (15.4 %) were female. The average age was 9.08 years, and drowning is most common in the 0-4 age group (33.3 %). The scene of the accident was an irrigation channel in 43.5 % of the cases, a river in 15.3 %, a sea in 12.8 %, a pool in 10.2 %, and a lake or pond in 7.69 %. CONCLUSION: Drowning deaths are a serious and preventable public health problem worldwide. There are strong correlations among lack of adult supervision, lack of precautions, and neglect.

Carcinoid tmour of the common bile duct: report of a case and a review of the literature.

Carcinoid tumours of the common bile duct are extremely rare lesions. In this article we report a case with an extrahepatic bile duct carcinoid tumour. A 40-year-old woman suffered from biliary colic and jaundice. Pre-operative computed tomography demonstrated a tumour in the biliary tract. At laparotomy there was a tumour invading the common bile duct. Common bile duct resection was performed. Carcinoid tumour of the common bile duct was diagnosed histopathologically. For extrahepatic bile duct carcinoid tumours surgical resection is the only treatment modality that offers a chance to provide a cure and prolonged disease-free survival. The favourable histopathological and biological features of these tumours encouraged the surgeons to use more aggressive approaches for advanced disease.

CYP2C19 polymorphisms in patients with gastric and colorectal carcinoma.

BACKGROUND: It has been reported that up to 80% of human cancers arise as a consequence of environmental exposure and host susceptibility factors. Environmental carcinogens are predominantly metabolized by the cytochrome P450 (CYP) superfamily of drug- or xenobiotic-metabolizing enzymes. Genetic variations in these enzymes affect individuals' susceptibility to carcinogens. AIM OF THE STUDY: The aim of this study was to evaluate the relationship between CYP2C19 polymorphism and susceptibility to these cancers by means of CYP2C19 genotyping among Turkish subjects. METHODS: DNAof subjects were isolated from leukocytes by high pure template preparation kit (Roche Diagnostics, GmbH, Mannheim, Germany) and genotypes were detected by LightCycler CYP2C19 Mutation Detection Kit by real-time PCR with LightCycler instrument (Roche Diagnostics, cat. no. 3113914). RESULTS: Being male was associated with a 3.5-fold (OR: 4.27, CI: 2.27-8.05) and 4.27-fold (OR: 3.50, CI: 1.948-6.301) risk for colorectal and gastric carcinoma, respectively. The CYP2C19*3 heterozygote genotype was not found in either gastric or colorectal carcinoma patients. Although the frequency of CYP2C19*2 heterozygote genotype is high in patients with gastric and colorectal carcinoma, it is not significantly associated with cancer (OR: 1.79, CI: 0.829-3.865 and OR: 1.998, CI: 0.961-4.154, respectively). CONCLUSION: Although the frequency of CYP2C19*2 heterozygote genotype is high in our patients with gastric and colorectal carcinoma, there is no the relationship between CYP2C19 polymorphism and susceptibility to these cancer.

Signet ring cell carcinoma of the breast as a source of pelvic floor metastatic mass. A case report.

Primary signet ring cell carcinoma of the breast is a very rare tumour. We present a case with pure signet ring cell carcinoma of the breast, which was recognized as metastasis on the pelvic floor, before developing breast symptoms and signs. A 40-year old woman was admitted with abdominal pain. First diagnostic effort revealed a cystic mass on the pelvic floor, compressing the colon and other neighbouring organs. A biopsy of the pelvic mass was performed. The histopathological examination revealed metastatic signet-ring cell carcinoma. At the time of the first operation, the mammary glands were not suspicious. No other sources of primary tumour were evidenced. An inflammatory sign developed in right breast two months after biopsy of the pelvic metastasis. The histopathology of the breast incisional biopsy revealed primary pure signet ring cell carcinoma of the breast. Because the oestrogen and progesterone receptor were negative in the tumoral tissue, the patient underwent chemotherapy followed by modified radical mastectomy, chemotherapy, and palliative resection of the metastatic mass. The patient was followed up for eight months. To our knowledge, in English literature, we believe that this case is the first report of signet ring cell carcinoma of the breast presenting with pelvic floor metastasis without breast sign.
