Lungs are separated into lobes by fissures, with three lobes on the right and two on the left. The fissures facilitate the uniform expansion of the whole lung. The anatomical knowledge of the fissures and the lobes of the lung is important for accurate interpretation of bronchopulmonary segments on X-rays and CT scans. 40 pairs of lungs removed from cadavers were utilized for the study of the p...

INTRODUCTION removed/ treated. Mostly, such types of fissures are Anal fissure is a distinct clinicopathological condition of situated eccentrically around the anal margin. the lower anal canal. It can be defined as a longitudinal ulcer in the anoderm usually in the posterior midline, less There is no trace of surgery of anal fissure in literature th frequently in the anterior midline, and rare...

The purposes of this study were to delineate the MR characteristics of CSF-like parenchymal or fissural cysts of the brain and to correlate them with the clinical findings. Clinical data and MR images of 34 patients with these abnormalities were reviewed. Pathologic correlation was not available. Two types of cystic lesions were identified and separated by location: medial temporal lobe cysts a...

Indocyanine green (ICG) emits fluorescence in the far-red domain under light excitation. ICG video angiography (ICG-VA) has been established as a useful method to evaluate blood flow in the operative field. We report the usefulness of ICG-VA for Sylvian fissure dissection in patients with subarachnoid hemorrhage (SAH). Subjects comprised 7 patients who underwent ICG-VA before opening the Sylvia...

Aims and objectives: The aim of this in vitro study was to evaluate self-adhering composite Dyad flow (Kerr, USA) as a pit and fissure sealant. The objectives were to assess the degree of microleakage with self-adhering composite Dyad flow and that with Fissurit F as pit and fissure sealants and, to compare the same between these two materials. Materials and Methods: 20 premolars extracted for ...

PURPOSE To evaluate tear film quality by rose bengal staining and its stability by breakup time, relating with palpebral fissure height and exophthalmos in patients with Graves' ophthalmopathy. METHODS We studied 54 eyes of 27 patients with Graves' ophthalmopathy, either in the inflammatory or in the chronic phase of the disease. The evaluation consisted of tear film qualitative analysis by r...

OBJECTIVE Recently, self-etching fissure sealants have been introduced to reduce technical sensitivity; however, their efficacy should be assessed. The aim of this study was to assess of the microshear bond strength of self-etching and conventional fissure sealants. MATERIALS AND METHODS Thirty non-carious third molars were randomly divided into three groups (N=10). Microcylinders of Concise ...

Herpes Zoster Ophthalmicus (HZO) is not an uncommon condition in the elderly and the immunocompromised. The common ocular manifestations include blepharoconjunctivitis, keratitis and uveitis. Dramatic presentations like orbital apex syndrome and superior orbital fissure syndromes occur rarely in patients with herpes zoster meningo-encephalitis. We report a patient with herpes zoster meningo-enc...

The optic fissure is a transient gap in the developing vertebrate eye, which must be closed as development proceeds. A persisting optic fissure, coloboma, is a major cause for blindness in children. Although many genes have been linked to coloboma, the process of optic fissure fusion is still little appreciated, especially on a molecular level. We identified a coloboma in mice with a targeted i...

Introduction. The appearance of a coloboma of the iris must have been known long before Walther (15) introduced the term in 1821 since the condition is easiiy visible. The word coloboma is derived from the Greek and means the part which is taken away in mutilation or injury or the part that is lacking, that is, a defect. In coloboma iridis, therefore, a section of the iris is lacking, often bil...
