Monotremes (echidna and platypus) are egg-laying mammals. One of their most unique characteristic is that males have venom/crural glands that are seasonally active. Male platypuses produce venom during the breeding season, delivered via spurs, to aid in competition against other males. Echidnas are not able to erect their spurs, but a milky secretion is produced by the gland during the breeding...

The conservative management of chronic calcaneal paratenonitis is time-consuming and often unsatisfactory. A new, safe and simple technique is described. The crural fascia on both sides of the tendon is incised and left open, adhesions around the tendon are trimmed away, the strongly hypertrophied portions of the paratenon are removed and mobilisation is begun immediately after operation. Betwe...

introduction: for a successful root canal treatment, canal must be obturated apically, coronally and laterally to prevent microleakage and canal reinfection. cold lateral condensation is the most popular method of canal obturation; an easy method with a controlled filling. cold lateral technique disadvantages are presence of void, possible vertical root fracture, and absence of a homogenous and...

INTRODUCTION Paraesophageal hernia with intrathoracic mesentericoaxial type of gastric volvulus is a rare clinical entity. The rotation occurs because of the idiopathic relaxation of the gastric ligaments and ascent of the stomach adjacent to the oesophagus through the hiatus defect, while the gastroesophageal junction remains in the abdomen. The open approach remains the gold standard therapy ...
