The management of keratoconus and post – LASIK ectasia included until recently spectacle correction, Hard Fitted Gas Permeable Contact Lenses, Intrastromal Corneal Ring Segments. All these interventions are purely symptomatic and their only aim is the improvement of visual function of patients, without interfering with the pathophysiology of the ectatic disorders. The only actual treatment for ...

PURPOSE The purpose of this study was to evaluate the effects of accelerated cross-linking (CXL) on corneal endothelium in keratoconus and postlaser-assisted in situ keratomileusis (LASIK) ectasia. DESIGN This study is a prospective nonrandomized controlled study. SETTING This study was conducted in Mansoura Ophthalmic Center (Mansoura University) and Al-Mostakbal Ophthalmic Center, Mansour...

Objectives: A retrospective study of last three years was undertaken to determine the histopathological spectrum of breast lesions with detailed study of interesting and uncommon cases, the features of which are helpful in management of the patients. Methods: Clinical features and histopathological findings were studied in 176 cases with emphasis on uncommon cases. Results: Out of the 176 cases...

The Ocular Response Analyzer (ORA) (Reichert Ophthalmic Instruments, Buffalo, NY) allows direct measurement of corneal biomechanical properties. Since its introduction, many studies have sought to elucidate the clinical applications of corneal hysteresis (CH) and corneal resistance factor (CRF). More recently, detailed corneal deformation signal waveform analysis (WA) has potentially expanded t...

Mucinous pancreatic neoplasms are uncommon disorders classified as either mucinous cystic neoplasms (mucinous cystadenoma or cystadenocarcinoma) or the more recently described intraductal mucin hypersecreting neoplasms (IMHN), also termed mucinous ductal ectasia. The mucinous cystic neoplasms share many common features with IMHN's but remain distinct clinico-pathologic entities. These tumors ha...

Fibroadenoma is the most commonly diagnosed benign tumour in adolescents and young women but spontaneous infarction in fibroadenoma is rarely seen. We report here a case of spontaneously infracted fibroadenoma in a 20 year old unmarried female without history of trauma or previous fine needle aspiration. It is important to recognize this entity because microscopic findings in an infarct are inf...

Polycystic kidney and liver disease was seen in a stillborn white-tailed deer (Odocoileus virginianus) fawn. Bilaterally enlarged kidneys were characterized by severe dilatation of all renal tubules. Glomeruli were sparse, small, and located within a dilated Bowman's capsule. The liver was characterized by marked periportal fibrosis, biliary hyperplasia, and bile duct ectasia with dilated ducts...

case presentation a preterm neonate with suspicious rt renal mass and oligohydramnios at prenatal ultrasound was hospitalized due to respiratory distress and hypertension. although postnatal ultrasound showed enlarged echogenic rt kidney and normal sized echogenic lt kidney, regarding to linear array transducer findings, arpkd was considered rather than renal mass. the diagnosis was confirmed a...

Polarity coordinates cell movement, differentiation, proliferation and apoptosis to build and maintain complex epithelial tissues such as the mammary gland. Loss of polarity and the deregulation of these processes are critical events in malignant progression but precisely how and at which stage polarity loss impacts on mammary development and tumourigenesis is unclear. Scrib is a core polarity ...

Salivary duct lithiasis is a condition characterized by the obstruction of a salivary gland or its excretory duct due to the formation of calcareous concretions or sialoliths resulting in salivary ectasia and even provoking the subsequent dilation of the salivary gland. Sialolithiasis accounts for 30% of salivary diseases and most commonly involves the submaxillary gland (83 to 94%) and less fr...
