Endovascular versus medical treatment of venous compression syndrome of the iliac vein - a systematic review.

The treatment of non-thrombotic iliac vein lesions (NIVL) remains debatable with many advocating conservative treatments, whilst others offering venous stenting. The objective of this review was to systematically assess the treatment options for symptomatic iliac vein compression syndrome (IVCS) in patients without evidence of thrombotic disease at the time of diagnosis. An online search of published literature looking for randomised controlled trials and observational studies that evaluated the treatment for symptomatic NIVL was performed. Nine studies were included with a total 953 patients of which 782 patients had NIVL. Patency rates ranged between 94.8%-100% in the first month, 88.2%-94.1% in six months and 73.4%-98% in 12 months, in patients with NIVL post stenting. Longer follow-up of up to 5 years shows promising patency rates of 94% in patients with IVCS. Patients with IVCS are likely to benefit from a combination of endovenous treatment at the time of diagnosis including stent placement to maintain lumen patency and prevent recurrent deep venpus thrombosis and/or postthrombotic syndrome.

A cubic calcium oxynitrido-silicate, Ca(2.89)Si(2)N(1.76)O(4.24).

The title compound, tricalcium oxynitride silicate, with composition Ca(3-x)Si(2)N(2-2x)O(4+2x) (x ≃ 0.12), is a perovskite-related calcium oxynitrido silicate containing isolated oxynitrido silicate 12-rings. The N atoms are statistically disordered with O atoms (occupancy ratio N:O = 0.88:0.12) and occupy the bridging positions in the 12 ring oxynitrido silicate anion, while the remaining O atoms are located at the terminal positions of the Si(O,N)(4) tetrahedra. The majority of the Ca(2+) cations fill the channels along [100] in the packing of the 12-ring anions. The rest of these cations are located at several positions, with partial occupancy, in channels along the body diagonals.

An experience of 42 cases of bronchoscopy at Saidu Group of Teaching Hospitals, Swat.

BACKGROUND: The objectives of our study were to find out the frequency in terms of age and sex of the patients, type and site of foreign bodies, clinical manifestations and management with rigid ventilating bronchoscope. METHODS: It was a descriptive study carried out in the department of otolaryngology and head and neck surgery at Saidu Teaching Hospital swat, and was conducted from March 2005 to March 2006. A total of 42 cases collected from March 2005 to March 2006, admitted through casualty, OPD and referred by pediatric unit. All of them subjected to bronchoscopy as an emergency as well as an elective procedure. RESULTS: A total of 42 cases were included in the study. In 37 cases (88.09%) foreign bodies were removed successfully, while 4 cases (9.52%) were having no foreign body, only mucous plug was removed. One patient (2.32%) died due to cardiac arrest.

Evaluation of aetiology and efficacy of management protocol of epistaxis.

BACKGROUND: Epistaxis is one of the commonest medical emergencies. It affects all age groups and both sexes. The cause may be local or systemic but in majority it is spontaneous and idiopathic. Trauma is considered to be a major aetiological factor. Various treatment protocols are utilized to control epistaxis derpending upon the type, severity and cause of bleeding. METHODS: This descriptive study was designed to evaluate the aetiology and efficacy of management protocol of epistaxis in a tertiary care setting. 313 patients underwent prospective evaluation by consultant and non-consultant doctors with considerable experience in Ear, Nose & Throat (ENT) emergencies management. Standard principles were followed in the management. RESULTS: This study demonstrated a bimodal distribution with incidence peaks in below 25 years & above 50 years of age. Males were affected twice more than the females (2.15:1.04). Anterior nasal bleeding was noted in majority of the patients. Anterior nasal packing was the most effective method of controlling anterior epistaxis. While posterior bleeding was controlled by posterior nasal packing with Foley's catheter. The most common cause was found to be trauma, followed by hypertension. CONCLUSION: It may be concluded from this study that epistaxis is the most common ENT emergency, affecting all age groups. It has a bimodal age presentation and affects males twice more than females. Anterior bleeding is more common than posterior bleeding. Epistaxis may be controlled with chemical/electro-cautery if the bleeding point is visible. In case of failure to localize or access a bleeding point or profuse bleeding, anterior nasal packing can effectively control majority of epistaxis. Foley's catheter is a good option that can be used for posterior nasal packing. Gelfoam may be used for controlling epistaxis in cases of bleeding disorders, when there is mucosal ooze.
