[Cystic dysplasia of rete testis associated with ipsilateral renal agenesis. Case report].

2003

Cystic dysplasia of the rete testis is a rare abnormality often associated with the ipsilateral agenesis of kidney. This malformation is due to a development defect of the mesonephric duct which is the cause of both the dilation of the testicular rete testis and renal agenesis. A case of this rare malformation, showing all the peculiarities described in the medical literature, is presented. A 3 years-4 months boy was examined for an asymptomatic left scrotal mass; thus, he underwent ultrasonography, which showed a multiple tubular and cystic dilatation of left rete testis, associated with the absence of left kidney, afterward confirmed by MAG3-radionuclide scan. Diagnosis was also validated…

Orthokeratinized odontogenic cysts: a Spanish tertiary care centre study based on HPV DNA detection

2018

Abstract Background The role of human papillomavirus (HPV) in orthokeratinized odontogenic cysts (OOCs) has rarely been studied. The objective is to describe the clinicopathological findings in a series of OOCs from a Spanish population that were investigated in relation to the possible presence of HPV. Methods A clinicopathological retrospective analysis followed by a molecular analysis of 28 high- and low-risk HPV genotypes was performed in OOC samples of patients seen during the last 15-years in a Spanish tertiary care center. Results Of 115 odontogenic cysts with keratinization, 16 cases of OOCs were confirmed and evaluated. OOCs occurred predominantly in the mandible of males (mean age…

Circadian variation in shedding of the oocysts of Isospora turdi (Apicomplexa) in blackbirds (Turdus merula): an adaptative trait against desiccation…

2009

5 pages; International audience; Many parasite species spend part of their life cycle in the external environment waiting for a new host. Emergence of parasites often occurs once a day, which may help to minimise mortality in an inhospitable environment and increase transition rates. Many intestinal parasites in birds are released in faeces only in the late afternoon. However, the adaptative significance of this pattern is unclear. One hypothesis is that a particular time of emergence may prevent parasite desiccation and therefore increase the parasite's life expectancy in the external environment. We tested this hypothesis experimentally using the blackbird (Turdus merula) infected with Is…

Ultrasound Evaluation of Thyroid Gland Pathologies After Radiation Therapy and Chemotherapy to Treat Malignancy During Childhood.

2015

The purpose of this study was to evaluate correlations between treatment of malignancy by radiation therapy during childhood and the occurrence of thyroid gland pathologies detected by ultrasonography in follow-up examinations.Reductions of thyroid gland volume below 2 standard deviations of the weight-specific mean value, occurrence of ultrasonographically detectable thyroid gland pathologies, and hypothyroidism were retrospectively assessed in 103 children and adolescents 7 months to 20 years of age (median: 7 years of age) at baseline (1997-2013) treated with chemoradiation therapy (with the thyroid gland dose assessable) or with chemotherapy alone and followed by ultrasonography and lab…

Jaw cysts at children and adolescence : a single-center retrospective study of 152 cases in southern Bulgaria

2010

One hundred fifty two cysts of the upper and lower jaw were examined at patients up to 18 years old treated in the Clinics of Maxillo-Facial Surgery, University Hospital, Plovdiv, Bulgaria for the period 1998 - 2007. Patients were distributed in four age groups (up to 4 years old, from 5 to 9 years old, from 10 to 14 years old, from 15 to 18 years old). Both sexes were constantly affected (52% male, 48% female). The biggest number cystic lesions were found in the third age group (48.7%). The mandible was preferable localization of the lesions (69.7%). Dentigerous cysts predominated (61.8%) - more affected was third age group (31.6%). Radicular cysts were observed two times less (31.6%) - mo…

The recurrence of odontogenic keratocysts in pediatric patients is associated with clinical findings of Gorlin-Goltz Syndrome

2019

Background Odontogenic keratocyst (OKC) is an odontogenic developmental cyst that presents distinct clinical behavior. This lesion has been described as dental cysts with keratinization since the 1930s, however the term "OKC" was established in 1956. This study aims to determine the frequency and features of OKC in children aged 0 to 14 years in an oral pathology service in Brazil. Material and Methods A retrospective study was performed to review cases of OKC in children diagnosed between 1986 and 2017. Clinical data were evaluated from medical records (gender, race, age, anatomical location, treatment, radiographic findings and follow-up). Results Ninety-seven cases of OKC were diagnosed …

Multiple intrahepatic pseudocysts in acute pancreatitis

2007

Liver pseudocysts are a very rare complication in acute pancreatitis with only a few cases previously described. The lack of experience and literature on this condition leads to difficulties in the differential diagnosis and management. We report herein a case of acute pancreatitis who developed multiple intrahepatic pseudocysts. After complete imaging evaluation, the diagnosis was still unclear and the patient was operated on. The presence of liver lesions in patients with acute pancreatitis should raise the possibility of intrahepatic pseudocysts.

Ileocecal duplication cysts: is the loss of the valve always necessary?

2014

Abstract Background Ileocecal (IC) duplication cysts are enteric duplications located at the IC junction, not clearly identified in all the published series. The reported treatment is IC resection and ileocolic anastomosis. It is well known that the loss of the IC valve has several adverse effects. This study is aimed at demonstrating that cyst removal together with the common ileal wall and following enterorrhaphy is possible, safe, and effective in preserving the IC region. Methods Medical records of 3 patients who underwent surgery for IC duplication between 2003 and 2013 were retrospectively reviewed evaluating follow-up results. Results All patients had an antenatal diagnosis of intraa…

A giant fetal urinoma in a neonate without detectable obstructive uropathy

2003

UNLABELLED Fetal urinoma is an uncommon finding in prenatal investigations. Most previous reports have, almost in every case, referred to the presence of an obstructive uropathy and thus to very high pressure in the upper urinary tract during fetal life. In this paper we present a prenatally detected fetal giant urinoma occurring in the absence of an apparent obstructive uropathy but associated with an ipsilateral vesico-ureteral reflux. CASE REPORT A 5-day-old boy, born after a caesarean section in the 37th week of gestation, but without any perinatal distress, came under our observation because of the evidence of a right upper quadrant abdominal mass. This mass had already been detected p…
