Introduction &

Low birth weight is one of the major causes of neonatal morbidity and mortality. Although in different studies the effect of kangaroo mother care on the growth of low birth weight infants had been examined، this study was planned to determine the effect of duration of KMC on the growth of LBW infants in NICU، Fatemieh hospital، Hamadan، 2012.

This study is a randomized clinical trial on 115 under weight infants who were randomly assigned into two groups. Up to 4 hours a day new born infants in the first group and more than 4 hours the second group، were cared for by their mother using KMC method. Both groups were analyzed and evaluated with regard to their weight، body tempera-ture، oxygen saturation، frequency of feeding، and infection in the third and fifth days after KMC. Data were analyzed using SPSS software،? 2 and t-test.

Mean (SD) weight، oxygen saturation، frequency of feeding in the group receiving Kangaroo care more than 4 hours were more than the recipients of kangaroo care less than 4 hours (P<0. 05). Significant differences between the groups in terms of body temperature، infection، and mortality were not observed.

KMC more than 4 hours a day is more beneficial than that of less than 4 hours a day in terms of developmental and physiological measures in low birth weight infants. There-fore، it highly suggested that the health practitioners and policy makers consider the benefits، impacts and strategies to increase the duration of KMC.

Ocular trauma is one of the important reasons of visual loss which can cause multiple damages to eyelid، eyeball and adenexal tissues. Furthermore، ocular trauma is one of the major causes of unilateral blindness and the third leading cause of hospi-talization in ophthalmology wards. The aim of this study is to determine the prevalence and characteristics of eye trauma at Farshchian hospital in Hamadan in 2012.

In this cross-sectional descriptive study، 70 patients with ocular trauma، admitted to Farshchian hospital، were studied. We assessed the age، sex، job، educational level، location، cause of trauma، its type and site of injury. The data was analyzed by SPSS 16 software and t،? 2 statistical tests.

The mean age of patients in this study was 24. 01 years (SD= 16. 04). Among 70 pa-tients، 58 people (82. 1%) were males and 12 patients (17. 1%) were females. The most com-mon cause of trauma was observed in 19 patients (27. 1%). The most common location of the trauma in this study was homing، seen in 28 patients (40%). Among the 70 patients، 29 peo-ple (41. 4%) had open globe injuries، 25 people had (35. 7%) closed globe injuries، 5 patients (7. 1%) had burning and 11 patients (15. 7%) had adenexal injury.

The results showed that most ocular traumas occur in the early ages and in males. The most common type of them is open globe injury and the most common cause is a sharp.

Diagnosis of periodontal osseous lesions is very important in deter-mining prognosis، treatment plan and maintenance in the long term. This diagnosis can be achieved by using radiography. The aim of this study is to compare accuracy of E speed films، bitewing PSP، panoramic PSP and CCD for identifying the extent of destruction of al-veolar bone in chronic periodontitis.

In this cross-sectional study، 272 interproximal surfaces were evaluated by 4 radiographic techniques after clinical examination by a periodontist and indication of flap surgery. The distance between CEJ and the alveolar crest was measured by Williams probe during the surgery and before osseous recontouring. These measures were considered as gold standard. This distance was measured using all 4 radiography techniques by 2 radi-ologists at standard conditions after calibration.

There was no significant difference between the 4 techniques. The mean distances from CEJ to alveolar crest in all techniques had no significant difference with gold standard، the least difference was in digital BW PSP and the greatest difference was in panoramic PSP. The non-measurable surfaces by E speed BW and panoramic PSP were the fewest and the most، respectively.

Better relative accuracy with regard to variation range، mean difference of meas-ures based on gold standard and number of shown surfaces was observed in digital and conventional BW compared to digital panoramic images.

Osteosarcoma (OS) is primary malignant bone tumor in which mesenchymal cell produce osteoid. OS of jawbones is uncommon، representing 4-8% of all OS. Case Report: This paper reports the case of a- 29 year-old female with an OS in mandibular first molar as exophitic lesion with smooth surface during 1 year. Based on the patient''s symptoms، differential diagnosis was lymphoma and malignant meshenshymal tumors. Exci-sional biopsy was done and histopatholigic feature proved to be OS.

Postoperatively، the patient was referred to the oncology department of Tehran Imam Khomeini hospital for further evaluation and treatment.
