Prevalence and risk indicators of gingivitis and periodontitis in a Multi-Centre study in North Jordan: a cross sectional study

Background  

There are limited data about the epidemiology and risk factors/indicators of gingivitis, aggressive periodontitis (AgP) and chronic periodontitis (CP) in Jordan. The aim of this study was to assess the prevalence and risk indicators of gingivitis, AgP and CP.     

Postoperative Necrotizing Enterocolitis Following Incarcerated Inguinal Hernia Repair: Report of a Case

The postoperative development of necrotizing enterocolitis (NEC) following major surgery in neonates has often been described. We report herein the case of an older infant in whom postoperative NEC developed following emergency repair of an incarcerated inguinal hernia.

Complications of varicella in healthy children in Izmir, Turkey

BACKGROUND: The purpose of the paper was to evaluate the indications of hospital admissions and complications of varicella infection in immunologically healthy children. METHODS: Between 1997 and 2001, patient records of children hospitalized due to varicella infection were reviewed. Incidence and clinical spectrum of complications and their distribution related to age and seasonal variations were analyzed. RESULTS: A total of 178 immunocompetent children were hospitalized for varicella complications during the study period. This resulted in a crude incidence of 6.3/100 000 population at risk. All hospital admissions were due to accompanying complications. The majority of complications occurred in preschool-age children with a median age of 3 years. No gender predominance was found. The most frequent complications were infectious complications, which were observed in 79 children (44%). Superinfections of the skin were present in 24 patients. Pneumonia was observed in 59 children: 49 had bacterial, 10 had viral pneumonia. Pyogenic arthritis was seen in two children and one had concomitant osteomyelitis. Group A beta-hemolytic streptococci were recovered from two patients with invasive bacterial infections. A total of 68 (38%) neurologic complications were observed. Cerebellar ataxia was present in 24, encephalitis was present in 17. Infectious complications occurred more frequently in younger children (median age: 2 years), whereas neurologic complications occurred at an older age (median age: 6 years). Hematologic complications were seen in nine children. There was a seasonal distribution of complications with a peak in January. CONCLUSION: Complications of varicella requiring hospitalization in immunocompetent children are more frequent than previously thought.     

Relationship between SP1 polymorphism and osteoporosis in β-thalassemia major patients

Background: β-Thalassemia is an autosomal recessive disease characterized by defective β-globin chain production. Osteoporosis is an important cause of morbidity in patients with β-thalassemia major. The pathogenesis of reduced bone mineral density (BMD) is multifactorial. A range of genetics factors have been implicated in other populations of patients with osteoporosis. Polymorphism at the Sp1 binding site of the collagen type I A1 ( COLIA1 ) gene is thought to be an important factor in the development of osteoporosis.
Methods: Alleles S and s , detected by presence of a G or T nucleotide, respectively in a regulatory site of the COLIA1 gene were investigated in 37 β-thalassemia major patients with osteoporosis and 92 controls without osteoporosis or osteopenia using polymerase chain reaction–restriction fragment length polymorphism.
Results: Fifteen and nine β-thalassemia major patients displayed SS and Ss genotypes, respectively, whereas 13 were found to have an ss genotype. The mean BMD of the β-thalassemia major patients with ss genotype was similar to those with the Ss and SS genotypes. In the control group, 77 and 15 subjects had SS and Ss genotypes, respectively, with no ss genotype. Allelic and genotypic distribution in patients were significantly different from controls.
Conclusion: Determining base substitutions at the Sp1 binding site on the COLIA1 gene in early years may be important in preventing osteoporosis in children with β-thalassemia major.     

Conservative treatment of scapular neck fracture: the effect of stability and glenopolar angle on clinical outcome

The aim of this study was to determine the effect of stability and glenopolar angle on the clinical outcome of conservatively treated scapular neck fractures. Eighteen patients with scapular neck fractures were treated with conservative treatment. Twelve of the 18 patients had surgical neck fractures, whilst six of them had anatomical neck fractures. Anteroposterior radiographs and computerised tomography were performed for each patient. Glenopolar angle was measured through anteroposterior radiographs in the scapular plane. After 3-5 weeks of immobilisation, a rehabilitation programme was started, throughout which all the patients were treated in a 3-phase rehabilitation programme. The mean follow-up was 25 months, and the Constant score was 78.83+/-8.12 point (range: 68-94 points). Patient gender and the type of scapular neck fractures had no effect on functionality or clinical outcome (p>0.05), whilst associated injuries significantly affected the clinical outcome (p<0.05). There was a positive correlation between the Constant score and glenopolar angle (r=0.891, p<0.05) and between the age and glenopolar angle (r=0.472, p<0.05).     

Mitomycin C prevents strictures in caustic esophageal burns in rats

BACKGROUND: Caustic esophageal injuries lead to stricture formation. Although a number of agents have been tried experimentally to prevent strictures, few have gained clinical application. The purpose of this study was to investigate the effectiveness of Mitomycin C (MMC), which inhibits fibroblastic proliferation in preventing caustic esophageal strictures. MATERIAL AND METHODS: Fifty-six rats were allocated into four groups. Caustic esophageal burns were created as described by Gehanno. Group A was instilled only with saline. Group B was injured and untreated. Groups C and D were injured and received topical MMC at 0.02 and 0.04% concentrations, respectively. At 28 days, stenosis index (SI), collagen deposition, and hydroxyproline content (HP) were determined in distal esophageal segments. Statistical analyses were done. RESULTS: Mean SI in Group B was significantly higher than others (P < 0.05). Mean SI was statistically higher in Group C than A and D and similar between groups A and D. The greatest accumulation of collagen was found in Group B, followed by Group C, D, and A, respectively. Collagen deposition in Group D was statistically lower than Group B (P < 0.01) and similar to Group C. Mean HP in Group B was statistically higher than others (P < 0.05), significantly higher in Group C than Group D (P = 0.047), and similar between Groups A and D (P = 0.73). CONCLUSION: MMC was effective in preventing strictures following experimental caustic esophageal injury, in a dose-dependent manner. We consider that it can gain clinical utilization with the establishment of effective mode, dose, and timing of therapy.     

Primary cerebellar glioblastoma multiforme

Primary glioblastoma multiforme of cerebellar hemispheres in adults is a rare condition. Most of them result from dedifferentiation of astrocytoma to glioblastoma. We present two cases of unusual de novo cerebellar glioblastomas, one of which is the giant-cell variant. We review their clinical behaviour with conventional MR imaging features and discuss the key findings that can lead to the correct diagnosis in sight of new MR imaging technologies.
