The aim of this cross-sectional study is to determine the prevalence of congenital colour vision defects among male secondary school students in Al-Madinah Al-Munawara city, Saudi Arabia. A total of 1154 male secondary school students were selected randomly through a multi-stage sampling method. Ishihara 24-plates was used to screen for colour blindness. The overall prevalence of congenital colour vision defects was 3.3% with 1% protanopes and 2.3% deuteranopes. The prevalence of congenital colour vision defect among Saudis was 2.48% and (5.48%) among non-Saudis. In conclusion, the prevalence of congenital colour vision defect among male secondary school students of Al-Madinah Al-Munawara city is comparable to previously reported in central Saudi Arabia, but lower than for Caucasian.

ntroduction: This study aimed to investigate the association between obesity, sedentary behaviour, television (TV) watching, small screen recreation (SSR), and perinatal life influences (breast-feeding, birth weight) among Jordanian school children. Methods: A total of 117 school children (56 obese and 61 normal weight) aged between 11 and 15 years were selected by using multistage cluster sampling method. Parents were requested to complete the first part of a questionnaire on family background,while the second part on adolescent sedentary behaviour was completed by the participants in the school. Anthropometric data were collected and presence of fat mass (%FM) was measured using bioelectrical impedance analysis. Results: Sedentary behaviour (hours/day) was significantly higher in obese school children compared to normal weight (4.43±0.60, 3.29±0.68, respectively; P <0.05), and positively associated with BMI (r=0.270, P<0.05). Normal weight children spent less time on watching TV (hours/day) compared to obese children (2.01±0.10, 2.34±0.16, respectively; P<0.05), and spent 2.55±1.6 (hours/day) in small screen recreation (SSR) compared to 3.89±1.0 (hours/day) of obese children. Both watching TV and SSR was significantly associated with BMI (r=0.260, r=0.201, respectively; P<0.05). Duration of exclusive breastfeeding (months) was significantly higher in normal weight than obese children (7.70±3.01, 5.05±2.01, respectively; P<0.05), and negatively associated with BMI (r=-0.254) and %FM (r =-0.330). Conclusion: Sedentary behaviour and watching TV were important risk factors for obesity among 11-15 years old Jordanian school children. A national policy promoting active living and reducing sedentary behaviour among school children is recommended.

Maxillary labial and buccal frena are considered as normal anatomic structures in the oral cavity. However, they may exist intraorally as a thick broad fibrous attachment and/or become located near the crest of the residual ridge, thus interfering with proper denture border extension resulting in inferior denture stability, retention and overall patient satisfaction. This case report highlights the importance of clinical examination and treatment planning which may mandate preprosthetic surgery prior to fabrication of a new conventional complete denture. Adequate patient satisfaction with conventional complete dentures can be significantly increased after frenectomy.

Psoriasis is chronic immunologically mediated inflammatory skin disorder affecting 1–3% of Swedish population. It is associated with impairments quality of life even in mild cases, while in severe cases it excess mortality .Oral manifestations of psoriasis are rare and has various clinical presentations which are often difficult to diagnose. Oral psoriasis is a rare entity that might be confused with other oral mucous membrane dermatoses; hence, it should be considered under differential diagnosis of oral mucous membrane disorders and confirmed histo-pathologically. The occurrences of cutaneous lesions along with oral lesions that are diagnosed histo-pathologically give definite diagnosis for oral psoriasis.

Objective: To investigate the efficacy of pomegranate (Punica granatum) peel extract as an alternative treatment on the white laboratory mice against giardiasis.
Methods: Experimental animals were divided into five groups, including Group A:control (infected untreated), Group B: infected and fed with pectin 7 days before infection, Group C: infected and fed with pectin starting from 7th day of infection, Group D:infected and fed with pomegranate peel extract 7 days before infection, and Group E: infected and fed with pomegranate peel extract starting from 7th day of infection.
Results: Results from this study revealed that the prevention rate in the experimental groups reached approximately 50%by the 10th day of using pomegranate peel extract. Moreover, stool cyst counts of groups showed a significant reduction in the shedding of cysts approximately 75.6%by day 20 post-infection. ELISA test showed a reduction in Giardia antigen in the stools of the experimental groups which received pomegranate peel extract. The cure rate of these groups was approximately 97.4% by 28th day of infection.
Conclusions: Our present findings indicated that the pomegranate peel extract proved to be valuable in prevention and treatment of Giardia lamblia infection. Further studies are required to determine the effective dose of pomegranate peel extract against Giardia lamblia infection.

Serum concentrations of sialic acid, fucose, prealbumin(PA ), ?1-antitrypsin (?1-AT), ?1-acid glycoproteins(?1-AGP), haptoglobin (HP) and transferrin (TF) were measured in 94 nasopharyngeal carcinoma and 65 cancer of larynx. Statistical evalution was made with stepwise discriminant analysis, and the discriminant functions were obtained. The effectiveness of allocation were examined on every one of all patients in the original data, Our results suggested, with the discriminant function equation consisting of serum PA, ?1-AT, ?1-AGP, HP and TF concentrations we could best separate the patients sufferng from nasopharyngeal or laryngeal carcinoma from the normal; the effective rate of discriminant was 87.36% and 88% for nasopharyngeal carcinoma from normal and laryngeal carcin-oma from normal respectively. However using discriminant function equation,composed of serum sialic acid, PA and ?1-AT, we could also discriminate nasopharyngeal or laryngeal carcinoma with recurrence from the one with non-recurrence, the effective rate of discriminant was 93.1% and 80% for nasopharyngeal carcinoma and cancer of larynx respectively

In this paper, we reported the radiographic characteristics of arterio-portal shunt in 59 cases with hepatocellular carcinoma. All eases were arbitrarily divided into three types, the peripheral, central, and mixed. The angiographic manifestations of all types were described in detail with emphases on discusion of the mechanism of the pormation of arterio-portal shun, and the orientation of interventional approach. We suggested that active and solemn attitude should be taken but with different ways be considered rather than ignoring it, for obtaining the positive results.

Anti-HBs,HBeAg,Anti-HBcIgM weremeasured in 322 cases of HBsAgnegative hepatitis.It was foundthat 120 of which were positive forthose HBV infecting markres,indi-cating that the HBV infecting ratewas very high(37.3%)in HBsAgNegative hepatitis.The authorspointed out that for the diagnosisof HBV infection all the infectingmarkers mentioned above should beroutinely detected,especially forAnti-HBcIgM.
