Pisiform-hamate coalition is a rare form of carpal coalition. Only 14 cases of pisiform-hamate coalition have been reported in the English-language literature. We present a case of asymptomatic bilateral pisiform-hamate coalition in a 16-year-old boy. We also review the embryology, pathogenesis, and clinical features of pisiform and hamate coalition, along with the associated multidetector computed tomography findings.

Pleural effusion might result in increased renal impedance as seen in cirrhosis, which is a rather complicated pathophysiological process, without causing any morphological changes in kidneys.

Objective: Maternal urinary tract infection is associated with intrauterine growth restriction, preterm delivery and low birth weight. The purpose of this study was to evaluate whether maternal urinary tract infection is related to neonatal urinary tract infection. Materials and methods: The present prospective study included 230 singleton neonates. The participants were divided into two groups based on in utero exposure to maternal urinary tract infections. The study group (exposure to maternal urinary tract infection) included 115 neonates and the control group (without exposure to maternal urinary tract infection) included 115 healthy neonates. Physical examination, urinalysis, urine culture and urinary system ultrasonography were carried out for all neonates. Results: There were 153 deliveries by cesarean section and 77 vaginal births. There was no statistically significant difference between the groups in terms of gender distribution, maternal age, birth weight, mode of delivery, gravida and gestational age. Although the difference was not significant, the incidence of low birth weight and preterm delivery were higher in the study group in comparison to that in the control group. There was a statistically significant higher rate of neonatal urinary tract infection in the study group compared with control group (25.2% vs. 7.8%, p<0.001). The most commonly discovered pathogens were Escherichia coli, followed by Klebsiella spp., Proteus spp., and Serratia spp. in the study group. Conclusion: The results of this study showed that the presence of maternal urinary tract infection may contribute to increased urinary tract infection frequency in the neonatal period. Neonates at risk for a urinary tract infection should be regularly monitored due to nonspecific clinical presentation.

To evaluate the accuracy of multislice computed tomography (MSCT) in staging of laryngeal cancer and comparison with histopathological findings. Twenty-eight patients diagnosed with laryngeal cancer and underwent surgical treatment were staged according to radiological and histopathological examination. The diagnostic accuracy of computed tomography (CT) for detecting cartilage involvement was as follows: sensitivity, 89 %; specificity, 80%. For detection of preepiglottic and paraglottic space invasion, MSCT has a sensitivity; 100% and 100 %, respectively, and a specificity; 55 % and 63%, respectively. Sensitivities and specifities of CT assessment for supraglottic mucosa, glottic mucosa and subglottic mucosa were 100 %, 100 % and 100 % respectively, 83 %, 85 % and 86 %, respectively. The high sensitivity value (100%) for the evaluation of the vocal cords may due to the images obtained during phonation. MSCT is a good, non-invasive imaging modality in staging of laryngeal cancer. The present study showed that CT was highly sensitive, but with relatively low specificity due to an increase in false positive values. The images obtained during phonation should be added to the neck CT protocol of the larynx cancer patients for improved evaluation of the glottic region, in particular.

Laringeal kanser tanısı alan ve cerrahi tedavi uygulanan 28 hasta radyolojik ve histopatolojik inceleme sonuçlarına göre evrelendi. Bilgisayarlı tomografinin (BT) kartilaj tutulumunu saptamada tanısal doğruluğunun sensitivitesi 89%; spesifitesi, 80%'dir. Preepiglottik ve paraglottik boşluk invazyonunun saptanmasında, MDBT'nin sırayla sensitivitesi 100%, 100%; spesitivitesi sırayla 55% ve 63% bulunmuştur. Supraglottik mukoza, glottik mukoza ve subglottik mukoza tutulumunun değerlendirilmesinde BT'nin sensitivite ve spesifite değerleri sırayla 100%,100% ve 100%, 83%,85% ve %86 idi. Vokal kordların değerlendirilmesindeki yüksek sensitivite değerleri 100%) fonasyon sırasında elde edilen imajlardan kaynaklanabilir. MDBT laringeal kanser evrelemesinde güvenilir ve non-invaziv bir görüntüleme metodudur. Çalışmamız gösterdi ki BT yüksek sensitivite değerlerine sahiptir. Ancak yalancı pozitif sonuçlardan dolayı nispeten düşük spesifite değerleri mevcuttur. Fonasyon sırasında elde olunan görüntüler, larinks kanserli hastalarda glottik bölgenin daha iyi değerlendirilmesi için boyun BT protokollerine eklenmelidir.

Objective Many studies showed that less-severe disease symptoms and fewer mortality rates have been reported in pediatric novel coronavirus disease 2019 (COVID-19) patients. In this study, we aimed to reveal the relationship between the volume of thymus gland, which provides T lymphocyte maturation in children, with the severity of lung involvement and blood laboratory values in pediatric patients with COVID-19 infection. Methods Thymus density and thymus and cardiac volumes were measured in pediatric COVID-19 patients and a control group that underwent thoracic tomography for reasons other than infection. Thymus/heart ratios were calculated to index the thymus volumes of the patients to their body dimensions. The severity of pneumonia was demonstrated by proportioning the involved lung parenchymal volume to the total lung volume in patients with typical involvement in thoracic tomography. The relationship between volumetric and blood laboratory values was statistically evaluated. Results Thymus density (p = 0.015) and thymus/heart ratio (p = 0.04) significantly differed between patients with COVID-19 infection and the control group. A correlation was observed between the pneumonia involvement rate and C-reactive protein (CRP) (k: 0.451, p = 0.08) and white blood cell (WBC; k: 0.419, p = 0.015) values in the thoracic tomography of the COVID-19 group. Conclusion The thymus gland is enlarged as an indicator of activation in COVID-19 infection. We hope that our study will guide new studies on the prognostic value of thymus size in lymphopenic patients with severe disease.
