ABSTRACT: Primary carcinoma of the sigmoid colon in an inguinal hernia is a rare condition. We present a 79-year-old man diagnosed with sigmoid colon carcinoma referred to 18F-FDG PET/CT for staging. PET/CT showed the primary lesion in the inguinal hernia into scrotum.

ABSTRACT: Bilateral adrenal metastases from bladder carcinoma have been reported rarely. We report an 86-year-old man with urothelial bladder carcinoma who had received chemotherapy and radiotherapy. Bilateral synchronous adrenal gland metastases were observed on 18F-FDG PET/CT.

ABSTRACT: Leptomeningeal metastasis is the metastatic spread of the disease to leptomeninges from solid tumors such as breast, lung cancer, and melanoma. Cauda equine syndrome is a neurological condition caused by compression of the cauda equine. The incidence of large cell neuroendocrine carcinoma in resected lung cancers appears to be 2.1% and 3.5%. The incidence of clinically diagnosed leptomeningeal metastasis in patients with solid tumors is approximately 5%. Here, we present cauda equine syndrome caused by the metastasis of large cell neuroendocrine carcinoma detected by 18F-FDG PET/CT and also 68Ga-DOTATATE PET/CT.

ABSTRACT: A 49-year-old woman was diagnosed with diffuse large B-cell lymphoma of the left ovary. Two months after the hysterectomy and bilateral salpingo-oophorectomy operation, the patient was referred to 18F-FDG PET/CT for staging. A mass lesion measuring 2.8 × 3 cm with intense 18F-FDG uptake was observed at right labium majus, which could be considered as a Bartholin's cyst or abscess. The lesion was excised, and non-Hodgkin lymphoma involvement of vulva was revealed by histopathology.

BACKGROUND/AIM: Understanding the causes of under-five deaths is key to realizing sustainable developmental goals. The aim of this descriptive study was to investigate the causes of under-five mortality in Istanbul during 2011 and compare the findings to those of 1988 and 2000. MATERIALS AND METHODS: All burial records of Istanbul were evaluated, and cemetery records of 1494 children, who died at under five years of age and were buried in Istanbul Metropolitan Municipality Cemeteries between 1 January and 31 December 2011, were analyzed. Several sociodemographic characteristics and causes of death were compared with the results of studies carried out in 1988 and 2000 in Istanbul with similar methods. RESULTS: Under-five mortality rate was lower in 2011 than in 1988 and 2000. Of all deaths, 58.8% had occurred in the neonatal period and most were in the first day of life, similarly to those of 1988 and 2000. The proportion of deaths in the age group of 1-4 years was found to be increasing. Prematurity and perinatal causes remained the main cause of death under five years of age in Istanbul during the 23-year period. Unknown causes, due to misclassification, were still seen in a relatively high proportion. CONCLUSION: Under-five mortality rate and death due to infectious diseases decreased in Istanbul from 1988 to 2011. Our findings showed a need for more emphasis on perinatal events and better evaluation of causes of death in clinical practice.

Simultaneous determination of nitrate and nitrite in gunshot residue has been conducted by capillary electrophoresis using an acidic run buffer (pH 3.5). In previously developed capillary electrophoretic methods, alkaline pH separation buffers were used where nitrite and nitrate possess similar electrophoretic mobility. In this study, the electroosmotic flow has been reversed by using low pH running buffer without any additives. As a result of reversing the electroosmotic flow, very fast analysis has been actualized, well-defined and separated ion peaks emerge in less than 4 min. Besides, the limit of detection was improved by employing large volume sample stacking. Limit of detection values were 6.7 and 4.3 µM for nitrate and nitrite, respectively. In traditional procedure, mechanical agitation is employed for extraction, while in this work the extraction efficiency of ultrasound mixing for 30 min was found sufficient. The proposed method was successfully applied to authentic gunshot residue samples.
