Genotypic strains of cariogenic mutans streptococci (MS) may vary in important virulence properties. In previous published studies, we identified 39 MS strains from pediatric patients undergoing full-mouth dental rehabilitation, including the removal and/or repair of carious lesions and application of antimicrobial rinse and fluoride varnish.The objectives of this current 1-year follow-up study are to assess the variability of MS strains that occur at 1-year post-rehabilitation and characterize the xylitol-resistance properties of MS strains that predominate.Plaque from five children with severe early childhood caries was collected 1-year post-rehabilitation. MS isolates were subjected to arbitrarily primed-polymerase chain reaction (AP-PCR) for identification of genetic strains and in vitro xylitol-inhibition experiments. To more precisely define strain distributions within each patient, we isolated large numbers of isolates per patient.MS strains diminished from several strains pre-rehabilitation, to one dominant strain at 1-year post-rehabilitation, with several new emergent strains. The majority of the clinical MS strains, as well as the Streptococcus mutans laboratory strains ATCC 25175 and 35668, were predicted to undergo 50% inhibition with 2.48-5.58% xylitol, with some clinical MS strains being significantly more resistant in vitro.Our follow-up study using patients from the original cohort demonstrates that specific MS strains are dominant at 1-year post-dental rehabilitation. Most of the clinical MS strains are similar in xylitol resistance to the attenuated S. mutans ATCC control strains, with some strains being more resistant to xylitol in vitro.

Eccentric Exercise Protocols for Patella Tendinopathy: Should we Really be Withdrawing Athletes from Sport? A Systematic Review.

The 2007 review by Visnes and Bahr concluded that athletes with patella tendinopathy should be withdrawn from sport whilst engaging in eccentric exercise (EE) rehabilitation programs. However, deprivation of sport is associated with a number of negative psychological and physiological effects. Withdrawal from sport is therefore a decision that warrants due consideration of the risk/benefit ratio. The aim of this study was to determine whether sufficient evidence exists to warrant withdrawal of athletes from sport during an eccentric exercise rehabilitation program. A systematic review of the literature was performed to identify relevant randomised trials. Data was extracted to determine whether athletes were withdrawn from sport, what evidence was presented to support the chosen strategy and whether this affected the clinical outcome. Seven studies were included. None of these reported high quality evidence to support withdrawal. In addition, three studies were identified in which athletes were not withdrawn from sport and still benefited from EE. This review has demonstrated that there is no high quality evidence to support a strategy of withdrawal from sport in the management of patella tendinopathy.

Carpal tunnel syndrome (CTS) is the most preva lent form of peripheral neuropathy. The efficacy of acupuncture in management of mild to moderate CTS has been investigated in limited studies with controversial results. The aim of this study was to assess the short-term effects of acupuncture in treatment of mild to moderate carpal tunnel syndrome.In a randomized controlled trial study, participants were randomly assigned to either control group which night splinting, vitamin B1, B6 and sham acupuncture for four weeks were administered, or intervention group that underwent acupuncture in 8 sessions over 4 weeks and night splinting. The clinical symptoms using global symptom score (GSS) and electrophysiological parameters were assessed at baseline and four weeks after the intervention.Of 72 patients met the inclusion criteria, 64 patients actually completed the 4 week intervention and were evaluated for the outcome. There was a statistically significant difference in GSS between two arms of treatment after the intervention (p < 0.001) Using repeated measure ANOVA, the GSS in acupuncture group was significantly different after 4 weeks (p <0.001). Among electrophysiological parameters, nerve conduction velocity (NCV) was significantly different between two groups after 4 weeks (p = 0.02). Other parameters showed no statistically significant difference after intervention (p > 0.05).Our findings indicated that the acupuncture can improve the overall subjective symptoms of carpal tunnel syndrome and could be adopted in comprehensive care programs of these patients.

Successful visual rehabilitation in a case of anterior megalophthalmos.

We report a case of 40-year-old female who presented with diminution of vision in both eyes. Ocular evaluation showed presence of bilateral megalocornea with deep anterior chamber, iridodonesis, cataract, and anterior embryotoxon. She was diagnosed with bilateral anterior megalophthalmos. She underwent an uneventful cataract extraction with standard posterior chamber intraocular lens implantation of overall large diameter in the left eye. Zonular dialysis was not evident intraoperatively despite the presence of iridodonesis. Postoperatively the intraocular lens was well centered throughout follow up. This case report reviews this rare disorder and highlights successful visual rehabilitation.

Isolated aglossia congenita: A rare case of oromandibular limb hypogenesis syndrome type I B.

J Oral Maxillofac Pathol. 2012 Sep; 16(3): 414-9
Gupta SR
Aglossia congenita (AC), congenital total absence of the tongue, is a very rare midline developmental anomaly, hypothesized to be associated with vascular disruption between the fourth and eighth week of gestation. It was classified by Hall (1971) as part of oromandibular limb hypogenesis syndrome (OLHS) type I B. Most of the cases reported with OLHS are actually hypoglossia with limb abnormalities whereas isolated aglossia is an extremely rare entity. A case of isolated AC is presented in a 28-year-old Indian male. He had long narrow face, tapering chin, low set ears, and microstomia. Intraorally, he had narrow palatal vault, constricted oropharyngeal isthmus, oligodontia, and maxillo-mandibular hypoplasia. Interestingly, the patient showed a median palatal groove, which has not been reported before. He also had an unusual acquired adaptive mechanism to compensate for aglossia. This report presents the manifestations of this rare syndrome, its complications, differential diagnosis, and rehabilitation strategies.
