Bilateral duplication of submandibular ducts ending in a ranula was revealed by sialography and confirmed by T2weighted SSh sequence using magnetic resonance cholangiopancreatography (MRCP) parameters. A literature search revealed 2 previous reports of submandibular duct duplication, but a ranula associated with submandibular duct duplication has not been previously reported. A review of congen...

A mucocele is a common, benign lesion of the oral cavity that develops following the extravasation or retention of mucous from a major or minor salivary gland. A pyogenic granuloma (PG) is also a common, benign condition characterized by proliferating capillaries that affect the skin and mucous membranes. The concurrent occurrence of a mucocele and a PG lesion has rarely been reported in the me...

Approximately 10-30% of intussusceptions that occur in adults are primary, frequently self-limited and not surgical (1, 2). The detection and frequency of these spontaneous and transient intussusceptions have been increased during the last years because of the widespread application of new imaging techniques as multislice computer tomography (CT) (1). But, in the majority of the obstructive cas...

Digital mucous cysts is a common benign skin disease usually present as solitary or a few soft, translucent to slightly bluish nodules. Here, we report the case of a 90-year-old male patient with numerous translucent nodules on his right fifth finger. Although he had one of them drained, they recurred afterward. Skin biopsy was done on the ventral side of the fifth distal phalange, and clear vi...

Bronchogenic cysts result from an abnormal budding or branching of the tracheobronchial tree. Approximately 30% of the cysts are located in the mediastinum and the remaining 70% in the lung. The cyst may be joined to the tracheobronchial tree by a fistula or by a fibrous band. Pulmonary bronchogenic cysts occur most frequently in the lower lobes, primarily on the right side. They are thin-walle...

sures retention or immediate memory, which is justifiably considered to be a significant aspect of mental capacity and one which is especially important clinically because of its close relationship to mental impairment. The test has obvious technical advantages, such as brevity of administration, lack of need for test materials and the objective character of the patient's performance. Neverthel...

Nine lab-scale continuous flow porous-pot bioreactors operating at various solids retention times and hydraulic retention times were conducted to simulate activated sludge (AS) systems and to evaluate the biodegradation kinetic models for the fate of 17α-ethinylestradiol (EE2), bisphenol-A (BPA), and triclosan (TCS) at the µg/L range. Mathematical models were applied to describe the degradation...

The coupled role of solution ionic strength (IS), hydrodynamic force, and pore structure on the transport and retention of viable Cryptosporidium parvum oocyst was investigated via batch, packed-bed column, and micromodel systems. The experiments were conducted over a wide range of IS (0.1-100 mM), at two Darcy velocities (0.2 and 0.5 cm/min), and in two sands (median diameters of 275 and 710 m...

Hydrocolpos has received little attention during the past decade (Dewhurst, 1963; Cook and Marshall, 1964). Consequently many doctors are not aware of this retention cyst of the vagina and when seen it is often misdiagnosed. On the other hand the related disorder of haematocolpos usually found at puberty is well known and more often suspected than confinned. Cook and Marshall (1964) recalled th...
