BACKGROUND The morphology of spermatozoa is a fundamental aspect to consider in fertilization, sperm pathology, assisted reproduction and contraception. Head, neck, midpiece, principal and terminal part of flagellum are the main sperm components to investigate for identifying morphological features and related anomalies. Recently, scanning near-field optical microscopy (SNOM), which belongs to ...

PURPOSE to determine factors associated to amniotic fluid volume and frequencies of fetal anomalies, in a reference center in Pernambuco. METHODS a transversal study performed in high-risk pregnant women submitted to obstetrical morphological ultrasound, from March 2002 to March 2006, at an institution from Recife, Pernambuco, Brasil. The intrauterine diagnosis was confirmed after birth. Soci...

Dental anomalies are clinically evident abnormalities which can cause vari¬ous dental problems, which may complicate orthodontic treatment planning. Clinical & radiological inspection play crucial role in identification of various anomalies. This study was carried over the period of 2 years to determine the pattern and distribution of various morphological dental anomalies among orthodontic pat...

Aneurysmal subarachnoid haemorrhage which has a serious mortality and morbitity ratio, occurs approximately 10/100.000 population per year and it is usally caused by rupture of a cerebral artery aneurysm. Aneurysms are classified saccular, fusiform or dissecan by morphological description. Vascular congenital anomalies of the cerebral vessels contribute to saccular aneurysm formation by increas...

During routine cadaveric dissection, we encountered multiple muscular anomalies in a 58-year-old embalmed male cadaver. All the variations were encountered on the flexor compartment of right upper limb. The anomalies include an axillary arch (Aa) in the axilla, a third head of biceps brachii (Thb) in the arm, a reverse palmaris longus (Rpl) and a Gantzer's muscle (Gm) in the forearm and an unus...

A total of 15 morphological abnormalities characteristic of dyserythropoiesis were evaluated in bone marrow smears stained with May-Grunwald-Giemsa stain. Abnormalities were classified as: (a) anomalies of the nucleus (binuclearity, multinuclearity, nuclear lobulation, budding, fragmentation, chromatin lumping and pyknosis, intranuclear bridging, extrusion of the nucleus); and (b) anomalies of ...
