Comparison of periodontal open flap debridement versus closed debridement with Er,Cr:YSGG laser

Background

Traditional periodontal open flap debridement (OFD) results in reduced pocket depth (PD), clinical attachment loss (CAL), gingival recession (GR) and postoperative pain and discomfort. The quest to overcome these shortcomings has led to research into Er,Cr:YSGG laser assisted pocket therapy (ELAPT). This study was designed to compare the clinical outcomes of ELAPT versus OFD.

Methods

Fifteen patients with a PD of ≥5 mm and ≤8 mm at two sites were selected. Test sites (Group 1) were treated by ELAPT and the control (Group 2) by OFD. Clinical parameters were recorded at baseline, 3 and 6 months and included Plaque Index (PI), Gingival Index (GI), modified Sulcular Bleeding Index (mSBI), PD, CAL and GR.

Results

Both treatments produced a reduction in PI, GI, mSBI and PD, an increase in GR, and a gain in CAL at 3 and 6 months. The mean gain of CAL in Group 1 at 3 and 6 months (1.60 ± 0.78 and 1.80 ± 0.63) was similar (p > 0.05) to the value of Group 2 (1.93 ± 0.88 and 2.00 ± 0.54). GR increased significantly (p < 0.05) only in Group 2 at 3 and 6 months (1.80 ± 0.56 and 1.87 ± 0.64) compared to Group 1 (0.50 ± 0.68 and 0.60 ± 0.74).

Conclusions

ELAPT compared with OFD results in similar CAL gains with less GR and significant reductions in PD, GI and mSBI, and may be considered as an alternative to surgical therapy.     

Quadriplegia in a child following adenotonsillectomy

Neurological deterioration in a child following routine surgery, although rare, has potentially life threatening consequences. We report the case of a child who, following adentonsillectomy, developed quadriplegia and acute respiratory distress due to previously undetected atlanto‐axial instability. Patients with atlanto‐axial instability often have mild or non‐specific symptoms, despite severe cervical cord compression. Subtle manifestations may be ignored or attributed to other disease processes, which render patients with undiagnosed atlanto‐axial instability at risk of serious neurological injury during general anaesthesia, particularly at the time of laryngoscopy and tracheal intubation.     

Update on ocular graft-versus-host disease

Ocular graft-versus-host disease (oGVHD) occurs as a complication following hematopoietic stem cell transplantation and is associated with significant ocular morbidity resulting in a marked reduction in the quality of life. With no current consensus on treatment protocols, management becomes challenging as recurrent oGVHD often refractory to conventional treatment. Most authors now diagnose and grade the disease based on criteria provided by the National Institutes of Health Consensus Conference (NIH CC) or the International Chronic oGVHD (ICCGVHD) consensus group. This article will provide an insight into the diagnostic criteria of oGVHD, its classification, and clinical severity grading scales. The inflammatory process in oGVHD can involve the entire ocular surface including the eyelids, meibomian gland, corneal, conjunctiva, and lacrimal system. The varied clinical presentations and treatment strategies employed to manage them have been discussed in the present study. The recent advances in ocular surface imaging in oGVHD patients such as the use of meibography and in vivo confocal microscopy may help in early diagnosis and prognostication of the disease. Researching tear proteomics and identification of novel potential tear biomarkers in oGVHD patients is an exciting field as they may help in objectively diagnosing the disease and monitoring the response to treatment.     

Isolation of Aspergillus nidulans from a case of fungal rhinosinusitis: a case report

A rare species i.e. A. nidulans is reported as a causative agent of allergic fungal rhinosinusitis in this study. It is an increasingly recognized type of chronic recurring hypertrophic sinus disease. There are more than 185 species of aspergillus and over 95% of all infections are caused by A. fumigatus, A. flavus and A. niger. A. fumigatus alone accounts for the large majority of cases of both invasive and non invasive aspergillosis. A young immunocompetent lady presented with bilateral nasal obstruction due to multiple polypoid mass at Sheth Vadilal Sarabhai General Hospital, Ahmedabad. Provisional diagnosis of sinonasal polyposis possibly due to fungal cause with infiltration in to nasal cavity was made. Bilateral functional endoscopic sinus surgery with polypectomy was done. The specimen was examined by standard methods and the fungus was identified as A. nidulans by slide culture.
