22021. Submandibular and intracranial hydatid cyst in an adolescent. (Abstract)

Submandibular and intracranial hydatid cyst in an adolescent. An unusual case of hydatid disease is reported. Review of the pertinent literature did not reveal any hydatid disease located simultaneously in both the intracranial and submandibular glands. This is the first case with hydatid disease occurring in both locations at the same time.The case of an 18-year-old is presented; the symptoms, findings, methods of diagnosis, and our approach for treatment are discussed; and the literature (...) is reviewed.The intracranial lesion was completely excised by left-sided frontoparietal craniotomy, and the mass in the right side of the submandibular gland was removed through a submandibular approach at the same session. The intact cyst was completely excised. Histological examination of both lesions confirmed the diagnosis of hydatid cyst by. Postoperative recovery was uneventful, and the patient was discharged on the seventh day.Hydatid cyst should be suspected during the evaluation of cervical masses

22022. The clinical value of image cytometry DNA analysis in distinguishing branchial cleft cysts from cystic metastases of head and neck cancer. (Abstract)

The clinical value of image cytometry DNA analysis in distinguishing branchial cleft cysts from cystic metastases of head and neck cancer. A branchial cleft cyst presents as a lump in the neck that, generally, is easily cured by surgical excision. The preoperative diagnosis is based on clinical examination and, especially in the Scandinavian countries, fine-needle aspiration cytology. However, at times, the histopathological analysis of the excised cyst reveals a cystic metastasis of squamous (...) cell carcinoma of the head and neck. If adequate diagnosis could be obtained preoperatively, patients would most likely fare better. The study was performed to investigate whether the diagnostic accuracy for these lesions could be improved preoperatively by image cytometry DNA analysis of the fine-needle aspiration cytology specimen.Image cytometry DNA analysis was performed on the preoperative fine-needle aspiration cytology specimen and the surgical specimens from 51 patients with solitary cysts

22023. Congenital dacryocystocele associated with intranasal cysts: diagnosis and management. (Abstract)

Congenital dacryocystocele associated with intranasal cysts: diagnosis and management. To improve the diagnostic and therapeutic database for congenital dacryocystoceles.Retrospective case study of 10 patients with dacryocystoceles treated in an academic integrated tertiary care practice. Management and outcomes are compared to previous reports in the literature.Between the years 1990 and 2001, 10 patients were diagnosed with dacryocystoceles. Seven were females, and 3 were males. Age ranged (...) from 1 to 75 days. Nine of 10 had a unilateral dacryocystocele, and 1 had bilateral dacryocystoceles. Epiphora was reported in 8 patients. Preoperatively, dacryocystitis, facial cellulitis, or both were present/developed in 2 patients. Symptoms of airway obstruction were present in 3 neonates. Surgery was performed in 9 of 10 patients and was a combined ophthalmology/otolaryngology surgery in 7 cases. Two patients were treated with probing only. Intranasal cysts were identified in all 7 patients

22024. Colonization of Soybean Cyst Nematode Females, Cysts, and Gelatinous Matrices by the Fungus Verticillium lecanii Full Text available with Trip Pro

Colonization of Soybean Cyst Nematode Females, Cysts, and Gelatinous Matrices by the Fungus Verticillium lecanii Heterodera glycines was grown in monoxenic culture on soybean roots and then inoculated with the antagonistic fungus Verticillium lecanii. Use of root explant cultures allowed evaluation of the fungus-nematode interaction with the nematode attached to roots or removed from the host, and avoided contamination with other fungi. From 16 hours to 14 days following inoculation, female (...) and cyst samples were examined with the light microscope, or prepared for either conventional or low-temperature scanning electron microscopy. Within 16 hours, hyphae had begun colonizing the gelatinous matrices (GM). The fungus proliferated in the GM of some specimens within a week, but was rarely seen in unhatched eggs. Fungus penetration holes in female and cyst walls were observed 3 days after inoculation; penetration through nematode orifices was not seen at that time. More cysts than females were

22025. Albendazole treatment of pulmonary hydatid cysts in naturally infected sheep: a study with relevance to the treatment of hydatid cysts in man. Full Text available with Trip Pro

Albendazole treatment of pulmonary hydatid cysts in naturally infected sheep: a study with relevance to the treatment of hydatid cysts in man. Albendazole was given orally to sheep with naturally occurring live pulmonary and hepatic cysts. The viability of pulmonary cysts was established before treatment by thoracotomy and needle puncture. Both 10 and 20 mg/kg/day doses were found effective in that no viable protoscoleces were found after six weeks' treatment in either group while untreated (...) controls still had viable cysts. In addition, treated animals showed macroscopic and electron microscopic changes. Bone marrow toxicity probably occurred in two sheep.

22026. Cyst fluid analysis in the differential diagnosis of pancreatic cysts. A comparison of pseudocysts, serous cystadenomas, mucinous cystic neoplasms, and mucinous cystadenocarcinoma. Full Text available with Trip Pro

Cyst fluid analysis in the differential diagnosis of pancreatic cysts. A comparison of pseudocysts, serous cystadenomas, mucinous cystic neoplasms, and mucinous cystadenocarcinoma. Pancreatic cystic lesions include inflammatory pseudocysts, benign serous tumors, and mucinous neoplasms, some of which are malignant. Clinical and radiologic indices are often inadequate to discriminate reliably among these possibilities. In an attempt to develop new preoperative diagnostic criteria to assist (...) in decisions regarding therapy, the authors have performed cyst fluid analysis for tumor markers (carcinoembryonic antigen: CEA, CA 125, and CA 19.9), amylase content, amylase isoenzymes, relative viscosity, and cytology on 26 pancreatic cysts. The cases included nine pseudocysts, five serous cystadenomas, 4 mucinous cystic neoplasms, 7 mucinous cystadenocarcinomas, and one mucinous ductal adenocarcinoma with cystic degeneration. Carcinoembryonic antigen levels were high (> 367) in all benign and malignant

22029. Loss of the polycystic kidney disease (PKD1) region of chromosome 16p13 in renal cyst cells supports a loss-of-function model for cyst pathogenesis. Full Text available with Trip Pro

Loss of the polycystic kidney disease (PKD1) region of chromosome 16p13 in renal cyst cells supports a loss-of-function model for cyst pathogenesis. It is not known whether mutations in the PKD1 gene cause autosomal dominant polycystic kidney disease (PKD) by an activating (gain-of-function) or an inactivating (loss-of-function) model. We analyzed DNA from cyst epithelial cells for loss of heterozygosity (LOH) in the PKD1 region of chromosome 16p13 using microsatellite markers. 29 cysts from (...) four patients were studied. Five cysts from three patients had chromosome 16p13 LOH. Four of the cysts had loss of two chromosome 16p13 markers that flank the PKD1 gene. In two patients, microsatellite analysis of family members was consistent with loss of the wild-type copy of PKD1 in the cysts. In the third patient, 16p13 LOH was detected in three separate cysts, all of which showed loss of the same alleles. Chromosome 3p21 LOH was detected in one cyst. No LOH was detected in four other genomic

22031. Pituitary-directed leukemia inhibitory factor transgene forms Rathke's cleft cysts and impairs adult pituitary function. A model for human pituitary Rathke's cysts. Full Text available with Trip Pro

Pituitary-directed leukemia inhibitory factor transgene forms Rathke's cleft cysts and impairs adult pituitary function. A model for human pituitary Rathke's cysts. Leukemia inhibitory factor (LIF) and LIF receptors are expressed in adenohypophyseal cells and LIF regulates pituitary hormone transcription and cell replication in vitro. Therefore, transgenic mice expressing pituitary-directed LIF driven by the rat growth hormone (GH) promoter were generated to evaluate the impact of LIF (...) by in situ hybridization. ACTH cells increased 2.2-fold, whereas gonadotrophs and thyrotrophs were unchanged. Serum GH was undetectable (< 0.78 ng/ml), PRL levels were one third of WT (P < 0.05), IGF-I levels were 30% of WT (P < 0. 001), and T4 was normal. 10 human pituitary Rathke's cysts studied all showed conclusive LIF immunoreactivity in cyst-lining cells. Thus, intrapituitary murine LIF overexpression causes cystic invaginations from the anterior wall of Rathke's cleft, suggesting failed

22032. Simple renal cysts in hypertensive patients: relation between cyst growing and anti-hypertensive therapy. (Abstract)

Simple renal cysts in hypertensive patients: relation between cyst growing and anti-hypertensive therapy. The study investigates relationship between simple renal cyst enlargement studied by ultrasonography and anti-hypertensive treatment. To this purpose we enrolled 42 patients with newly diagnosed hypertension affected by simple renal cysts. Fourteen were randomly assigned to treatment with ACE-Inhibitors (group 1), twelve to diuretics (group 2) and sixteen to Ca-Antagonists (group 3 (...) ). Patient performed a basal ultrasonography to evaluate basal cyst dimension before starting anti-hypertensive treatment. Following 12 months of the anti-hypertensive regimen, a new echograph was performed to evaluate changes in cyst size. A control group consisting of 15 patients with normal blood pressure and simple renal cysts was enrolled (group 0). An enlargement of cysts was detected in all patients. However, the enlargement observed in patients treated by Ca-Antagonists was significantly greater

22033. Sonography of fetal choroid plexus cysts: detection depends on cyst size and gestational age. (Abstract)

Sonography of fetal choroid plexus cysts: detection depends on cyst size and gestational age. To establish diagnostic criteria for the diagnosis of fetal choroid plexus cysts across gestation.Prenatal sonographic images of 166 fetuses without choroid plexus cysts were prospectively collected from 13 weeks to term. Texture characteristics of the choroid plexus regions were analyzed to quantify changes as a function of gestational age. A set of 20 fetal sonographic images with choroid plexus (...) cysts were used to create cyst prototypes (1.5-2.5 mm), which were randomly embedded into normal choroid plexus images from varying gestational ages. A test set of 544 images was created, which included 408 images with choroid plexus cysts and 136 images without choroid plexus cysts. Four observers following a blinded study design evaluated the presence of choroid plexus cysts in the images. The influence of cyst size and gestational age on the detection of cysts was measured with receiver operating

22035. Paradental cyst mimicking a radicular cyst on the adjacent tooth: case report and review of terminology. (Abstract)

Paradental cyst mimicking a radicular cyst on the adjacent tooth: case report and review of terminology. A distinctive form of paradental cyst can occur on the buccal and apical aspects of erupted mandibular molars. This cyst has peculiar clinical and radiographic features, although the microscopic findings are the same as those of odontogenic inflammatory cysts. Diagnostic and therapeutic problems can occur when this lesion is misinterpreted as a radicular cyst. The purpose of this paper (...) is to present an additional case of a paradental cyst in the buccal and mesial aspects of a mandibular second molar involving the apical area of a mandibular first molar. The difficulty of diagnosis, treatment, and controversies regarding terminology are also discussed.
