Pituitary homeobox 1 (Ptx1) is a homeodomain-containing transcription factor acting on transcription of all pituitary hormone genes. Its expression is first detected in the stomodeal ectoderm and is maintained in all derivatives of this structure, including Rathke's pouch. We now show that Ptx1 is expressed in all pituitary cells but that it is differentially expressed in different lineages at ...

A 66-year-old woman with a diagnosis of asymptomatic Rathke's cleft cyst had been observed for almost 2 years and was admitted to our hospital in June 1992 because of high fever and loss of consciousness. Ophthalmological examination revealed right Horner's sign and ophthalmoplegia. A tentative diagnosis of bacterial meningitis was made based on the results of a lumbar puncture. T1-weight MRI s...

Certain morphological features of intracellular crystal formation within the midgut glands of Limnoria lignorum (Rathke) have been studied with the electron microscope and cytochemical methods. A correlation has been established between Golgi membranes and formation of the crystals. The Prussian blue reaction reveals quantities of iron localized in the intracellular crystals and in small granul...

Rathke cleft cyst is described as benign intrasellar cyst. They are mostly small and asymptomatic; they may become large enough to cause symptoms by compression of intrasellar or suprasellar structures. We report on a case of spontaneous regression of a symptomatic RCC with subsequent recovery of preexisting endocrine dysfunction and resolution of headaches. A 60-year-old man complained about h...

OBJECTIVE Traditional neurosurgical practice calls for administration of peri-operative stress-dose steroids for sellar-suprasellar masses undergoing operative treatment. This practice is considered critical to prevent peri-operative complications associated with hypoadrenalism, such as hypotension and circulatory collapse. However, stress-dose steroids complicate the management of these patien...

BACKGROUND Although percutaneous kyphoplasty (PKP) could achieve rapid pain relief for the elderly with osteoporotic vertebral compression fracture (OVCF), some patients still had risks of suffering vertebrae delayed union which led to persisting pain and vertebral collapse. Preventing the delayed vertebral union could reduce the further morbidities and medical costs for patients with OVCF afte...

To estimate incidence of cleft lip and cleft palate among Jordanian infants and to identify associated anomalies, we carried out a prospective, hospital-based study over a 5-year period, January 2000-January 2005. The total number of liveborn infants was 25 440, 60 of whom (2.4/1000) had facial clefts: 20 (33%) with cleft lip, 15 (25%) with cleft palate and 25 (42%) with both. Congenital heart ...

AIMS AND OBJECTIVES To assess the effect of presurgical nasoalveolar molding (PNAM) therapy in the management of patients with nonsyndromic unilateral cleft lip and palate (UCLP). MATERIAL AND METHOD Ten patients with UCLP treated from 2009 to 2012. The initiation for PNAM treatment was 7 days and the average time of the treatment was 175 days. Measurements on patients and of casts were made,...

Immunohistochemical characterization of 14 cases of intracranial cysts was performed. Among these 14 cases, five different types of cysts were represented; Rathke's cleft cyst (4 cases), neurenteric cyst (2 cases), colloid cyst (1 case), choroidal epithelial cyst (2 cases) and arachnoid cyst (5 cases). Immunohistochemical evaluation utilized antibodies to glial fibrillary acidic protein (GFAP),...

Headache is one of the most frequent physical complaints of humans. Although headaches are generally benign, neuroimaging studies are frequently performed in clinical practice for the fear of missing a serious underlying disease. Arachnoid cysts are cavities with a content similar to cerebrospinal fluid, frequently communicating with the subarachnoid space. Arachnoid cysts are often discovered ...
