As a method of preclinical secondary prevention, screening is the rapid administration of a simple test to distinguish individuals who may have a condition from those who probably do not have a condition. It can be an effective, efficient tool in preventive health care if used for conditions applicable to the screening model and directed toward an at-risk population. A unique characteristic and significant advantage of screening is that it can be applied to individuals and groups. Three questions provide a means of analyzing the screen ability of a disease: 1. Is the condition is significant? 2. Can screening for the condition be dons? 3. Should screening for the condition be done? Screening programs are not appropriate for all conditions or all communities. Alternative methods of reaching the desired health outcome should always be considered. Screening in health care presents numerous roles for health care workers and provides them with a valuable preventive tool in the care of healthy individuals.

Maxillofacial prosthetic materials are used to replace the facial parts that are lost through disease or trauma. Acquired and congenital defects of the face create an unfortunate condition for an individual. For the individual to lead a comfortable life requires facial rehabilitation, thus a reassessment of materials used in the field of maxillofacial prosthesis seems desirable. The materials have travelled a long way from wood, wax, primitive metal, leather, rubber, etc. to the latest biomedical material such as polymers. While the newer materials have exhibited some excellent properties they have also exhibited some frustrating deficiencies. We still are in search of a material comprising all the ideal properties so as to best restore a maxillofacial defect. The prosthodontist are limited by the inadequate material available for facial restorations, movable tissue below, difficulty in retaining large prostheses and the patient's capacity to accept the final result. Hence this review article discuss briefly about the evolutionary changes the maxilla-facial prosthetic material has undergone during these decades

A retrospective review is aimed to evaluate the difficulties encountered during laparoscopic cholecystectomy (LC) and local factors influencing the conversion. The data collected from 300 patients had LC over one year period, in relation to clinical presentation. Twenty two cases were converted to open cholecystectomy. The reasons for conversion were difficult anatomy in 50%, bleeding 41%, and 9% due to individual center related factors. It was evident that the conversion rate was high especially in cases with acute cholecystitis and post biliary pancreatitis. In conclusion, a learning curve is required to build up the experience and it should be organized and phased. Laparoscopic surgery should be done in an optimized environment. LC for acute cholecystitis must not be delayed beyond 72 hours.

The present study deals with the antimicrobial activity of palmcandy against throat infection causing bacteria. Generally the throat infection is caused by Streptococcus, Staphylococcus and occasionally by Candida, Escherichia coli etc. The antimicrobial activity of some plant extract will not produce lethal effects to humans but they heal many infectious diseases. The palmcandy is taken for its antibacterial value in throat infection. It is used locally for treating throat infection. Disk diffusion method is carried out by swabbing the test sample in Muller Hinton agar plates, Whatmann filter paper disk No:1 Containing palmcandy extract are placed to examine their antimicrobial activity and kept it for incubation at 37oc for 24 hrs. On the basis of zone formation result is reported.

A total of 647 stool samples were obtained from patients, who came to laboratory of Medical Laboratory Science Department of Engineering and Technology Faculty in Wadi Al-Shati province, southern west, Libya for stool examination. Monthly and seasonal prevalences of Blastocystis hominis were evaluated in period from March 2004 to February 2008. The result indicated that the highest prevalence was in the summer season (June to August). Significant different in the prevalence of B. hominis infection was found between the summer and winter seasons (p< 0.05). These results revealed that B. hominis infection is probably related to weather condition, being more common in hot weather or summer season, therefore the results indicated that there was a possible seasonality of Blastocystis hominis infection.

During the past 3 decades, non-operative management (NOM) has been demonstrated to be an effective therapeutic option in hemodynamically stable patients. We retrospectively reviewed our experience of the last 7 years in NOM of blunt abdominal trauma. Between January 1998 and July 2005, 123 patients with blunt abdominal trauma and injury to liver, spleen and pancreas were admitted to our hospital. Fifty-eight of them (47.2 %) were submitted to NOM; 5 (8.6 %) sustained both hepatic and splenic injuries. We treated nonoperatively 32 hepatic injuries (62.7 % of the total hepatic injuries) 27 splenic injuries (33.7 % of total splenic injuries) and 3 pancreatic injuries (75 % of the total pancreatic injuries). There were no mortality and no complications. We submitted to angiography and embolization one patient with a grade V hepatic injury, hemodynamically stable, showing a "contrast pooling" at abdominal CT scan; the patient was successfully managed nonoperatively. The overall success rate of NOM was 98.5 %; the only NOM failure was a patient with both splenic and hepatic injury. Success rate for injuries to the liver was 96.9%, spleen was 96.3%, and to the pancreas was 100%. We conclude that hemodynamically stable patients sustaining intra-abdominal injury can be safely managed non-operatively.

Clavicle fractures have been treated in the past by conservative means such as figure of eight bandage, sling and swathe etc. Although acceptable for middle and medial fractures, distal clavicle fractures often require open reduction and internal fixation. We present the results of 11 cases treated with open reduction and internal fixation with kirshner wires. Our results were good.

Spinal anaesthesia for cesarean sections are often accompanied by a reduction in maternal blood pressure. Maternal hypotension may lead to a reduction in uteroplacental blood flow with consecutive fetal acidosis. Spinal block causes paralysis of preganglionic sympathetic fibers, while ketamine induces activation of the sympathetic nerves. The aim of our study was to compare circulatory changes in patients who received ketamine intravenously and did not receive ketamine during spinal anaesthesia. This study involved 70 patients ASA I and, II scheduled to undergo a spinal anaesthesia for a cesarean section, and were randomly allocated into one of two groups (A or B). Group A {n=35} received 10 ml\kg of ringer lactate intravenously preoperatively and received 0.25 mg\kg of ketamine intravenously immediately after the spinal agent injection (spinal agent was 2 ml hyperbaric bupivacaine 0.5%). Group B {n=35} only received 10 ml\kg of ringer lactate intravenously preoperatively and received 0.25 mg\kg of placebo intravenously immediately after the spinal agent injection spinal agent was 2 ml hyperbaric bupivacaine 0.5%" preoperatively. The incidence of hypotension was evaluated from the time of spinal agent injection to delivery. Hypotension was defined as a 20% decrease in mean arterial blood pressure below the baseline. This study indicated that the incidence of hypotension was significantly lower in patients who received ketamine {P value < 0.05}.
