Fulltext Multidisciplinary approach for management of a patient with fibrous dysplasia of maxilla

Eachempati P, Aggarwal H, Shenoy V, Baliga M

BMJ Case Rep, 2015 Aug 05;2015.
PMID: 26245286 DOI: 10.1136/bcr-2015-210330

Fibrous dysplasia is a non-neoplastic hamartomatous developmental fibro-osseous lesion of bone. Monostotic fibrous dysplasia is more common than the polyostotic form and usually involves jaw bones, ribs and femur. Maxillary lesions may extend to involve the maxillary sinus, zygoma, sphenoid bone and floor of the orbit and require surgical intervention resulting in an acquired defect of the involved site. A multidisciplinary team approach involving an oral pathologist, oral surgeon, oral medicine expert and maxillofacial prosthodontist is required for successful treatment and rehabilitation of such patients. This article describes a case of a patient with fibrous dysplasia of the left maxilla, which was successfully managed by integrating surgical intervention and postoperative rehabilitation, with a surgical obturator and an interim partial denture prosthesis that successfully limited the detrimental effects of surgery, and helped the patient in resocialisation, thereby improving her quality of life.
Different Intraorbital Implant Situations and Ocular Prosthetic Rehabilitation

Aggarwal H, Kumar P, Eachempati P, Alvi HA

Enucleation is the removal of the entire globe of the eye and a portion of the optic nerve, while evisceration involves the removal of the contents of the globe leaving the sclera, extraocular muscles, and optic nerve. Following enucleation or evisceration, intraorbital implants are routinely placed to enhance the prosthetic outcome in addition to restoring the lost orbital volume. Current practice employs intraorbital implants made of nonporous silicone, hydroxyapatite, or porous polyethylene. Intraorbital implant selection and placement, being a highly demanding procedure in terms of knowledge, skill, and expertise, may be associated with a multiplicity of technical and surgical errors. Complications are usually minimal with these implants, but they do occur. The literature reveals many articles related to intraorbital implants, their benefits, and complications; however, the literature regarding the effect of various intraorbital implant situations on the subsequent prosthetic rehabilitation is markedly scarce. Moreover, the need for interdisciplinary surgical and prosthetic interventions required for successful rehabilitation in cases of compromised implant situations has been underemphasized. Hence, this review aimed to evaluate the effect of different intraorbital implant situations on ocular rehabilitation and the required interdisciplinary surgical and prosthetic treatment approach for rehabilitation of enucleated/eviscerated sockets with compromised implant situations, to provide a critical appraisal, and to present a simplified management strategy.

Multidisciplinary Approach for Management of a Patient with Oral Mucosal Malignant Melanoma

Eachempati P, Aggarwal H, Shenoy VK, Baliga M

J Coll Physicians Surg Pak, 2018 Sep;28(9):S187-S189.
PMID: 30173693 DOI: 10.29271/jcpsp.2018.09.S187

Oral mucosal melanoma is rare and more aggressive than cutaneous melanoma. Hard palate and maxillary alveolar crest are most commonly involved. Multidisciplinary team approach is necessary for successful management of this tumor. The main treatment modality is surgical resection, which usually results in impaired mastication, deglutition, speech, oral competence and significant cosmetic deformity. Here, a rare case of oral mucosal melanoma of mandibular gingiva in a 44-year man is reported, who was treated by en-block mandibular resection followed by adjuvant therapy with high dose interferons (IFN) - 2b. Following two weeks of healing period, prosthetic rehabilitation of the patient was done with an interim removable denture prosthesis, which effectively limited the unfavourable effects of surgery and helped him in resocialisation.
Interventions for treating oro-antral communications and fistulae due to dental procedures

Kiran Kumar Krishanappa S, Prashanti E, Sumanth KN, Naresh S, Moe S, Aggarwal H, et al.

BACKGROUND: An oro-antral communication is an unnatural opening between the oral cavity and maxillary sinus. When it fails to close spontaneously, it remains patent and is epithelialized to develop into an oro-antral fistula. Various surgical and non-surgical techniques have been used for treating the condition. Surgical procedures include flaps, grafts and other techniques like re-implantation of third molars. Non-surgical techniques include allogenic materials and xenografts.
OBJECTIVES: To assess the effectiveness and safety of various interventions for the treatment of oro-antral communications and fistulae due to dental procedures.
SEARCH METHODS: We searched the Cochrane Oral Health Group's Trials Register (whole database, to 3 July 2015), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2015, Issue 6), MEDLINE via OVID (1946 to 3 July 2015), EMBASE via OVID (1980 to 3 July 2015), US National Institutes of Health Trials Registry (http://clinicaltrials.gov) (whole database, to 3 July 2015) and the World Health Organization (WHO) International Clinical Trials Registry Platform (http://www.who.int/ictrp/en/) (whole database, to 3 July 2015). We also searched the reference lists of included and excluded trials for any randomised controlled trials (RCTs).
SELECTION CRITERIA: We included RCTs evaluating any intervention for treating oro-antral communications or oro-antral fistulae due to dental procedures. We excluded quasi-RCTs and cross-over trials. We excluded studies on participants who had oro-antral communications, fistulae or both related to Caldwell-Luc procedure or surgical excision of tumours.
DATA COLLECTION AND ANALYSIS: Two review authors independently selected trials. Two review authors assessed trial risk of bias and extracted data independently. We estimated risk ratios (RR) for dichotomous data, with 95% confidence intervals (CI). We assessed the overall quality of the evidence using the GRADE approach.
MAIN RESULTS: We included only one study in this review, which compared two surgical interventions: pedicled buccal fat pad flap and buccal flap for the treatment of oro-antral communications. The study involved 20 participants. The risk of bias was unclear. The relevant outcome reported in this trial was successful (complete) closure of oro-antral communication.The quality of the evidence for the primary outcome was very low. The study did not find evidence of a difference between interventions for the successful (complete) closure of an oro-antral communication (RR 1.00, 95% Cl 0.83 to 1.20) one month after the surgery. All oro-antral communications in both groups were successfully closed so there were no adverse effects due to treatment failure.We did not find trials evaluating any other intervention for treating oro-antral communications or fistulae due to dental procedures.
AUTHORS' CONCLUSIONS: We found very low quality evidence from a single small study that compared pedicled buccal fat pad and buccal flap. The evidence was insufficient to judge whether there is a difference in the effectiveness of these interventions as all oro-antral communications in the study were successfully closed by one month after surgery. Large, well-conducted RCTs investigating different interventions for the treatment of oro-antral communications and fistulae caused by dental procedures are needed to inform clinical practice.
Interventions for treating post-extraction bleeding

BACKGROUND: Post-extraction bleeding (PEB) is a recognised, frequently encountered complication in dental practice, which is defined as bleeding that continues beyond 8 to 12 hours after dental extraction. The incidence of post-extraction bleeding varies from 0% to 26%. If post-extraction bleeding is not managed, complications can range from soft tissue haematomas to severe blood loss. Local causes of bleeding include soft tissue and bone bleeding. Systemic causes include platelet problems, coagulation disorders or excessive fibrinolysis, and inherited or acquired problems (medication induced). There is a wide array of techniques suggested for the treatment of post-extraction bleeding, which include interventions aimed at both local and systemic causes.
OBJECTIVES: To assess the effects of interventions for treating different types of post-extraction bleeding.
SEARCH METHODS: We searched the following electronic databases: The Cochrane Oral Health Group Trials Register (to 22 March 2016); The Cochrane Central Register of Controlled Trials (CENTRAL; The Cochrane Library 2016, Issue 2); MEDLINE via OVID (1946 to 22 March 2016); CINAHL via EBSCO (1937 to 22 March 2016). Due to the ongoing Cochrane project to search EMBASE and add retrieved clinical trials to CENTRAL, we searched only the last 11 months of EMBASE via OVID (1 May 2015 to 22 March 2016). We placed no further restrictions on the language or date of publication. We searched the US National Institutes of Health Trials Register (http://clinicaltrials.gov), and the WHO Clinical Trials Registry Platform for ongoing trials (http://apps.who.int/trialsearch/default.aspx). We also checked the reference lists of excluded trials.
SELECTION CRITERIA: We considered randomised controlled trials (RCTs) that evaluated any intervention for treating PEB, with male or female participants of any age, regardless of type of teeth (anterior or posterior, mandibular or maxillary). Trials could compare one type of intervention with another, with placebo, or with no treatment.
DATA COLLECTION AND ANALYSIS: Three pairs of review authors independently screened search records. We obtained full papers for potentially relevant trials. If data had been extracted, we would have followed the methods described in the Cochrane Handbook for Systematic Reviews of Interventions for the statistical analysis.
MAIN RESULTS: We did not find any randomised controlled trial suitable for inclusion in this review.
AUTHORS' CONCLUSIONS: We were unable to identify any reports of randomised controlled trials that evaluated the effects of different interventions for the treatment of post-extraction bleeding. In view of the lack of reliable evidence on this topic, clinicians must use their clinical experience to determine the most appropriate means of treating this condition, depending on patient-related factors. There is a need for well designed and appropriately conducted clinical trials on this topic, which conform to the CONSORT statement (www.consort-statement.org/).

Atomically Tailored Zn-ZIF-8 via RuNi Nanoalloy Replacement for Improved Photocatalytic H2 Evolution

Jamma A, Vennapoosa CS, Annadata HV, Ghosh B, Govu R, Aggarwal H, et al.

ACS Appl Mater Interfaces, 2024 Nov 27;16(47):64681-64690.
PMID: 39535905 DOI: 10.1021/acsami.4c11732

In this study, we developed a solid-state atomic replacement method for metal catalysts, enabling the exchange of metal atoms between single atoms and nanoalloys to create new combinations of nanoalloys and single atoms. We observed that partial metal interchange occurred between the RuNi nanoalloy and Zn from the zeolitic imidazolate framework-8 (ZIF-8) on a carbon-nitrogen framework (CNF) at a high temperature of 900 °C, leading to the creation of RuZn nanoparticles and single nickel atoms (Ni-CN). Extended X-ray absorption fine structure (EXAFS) and X-ray absorption near edge structure (XANES) analyses revealed that Ni is atomically dispersed within (RuZn)/Ni-CN. This finding confirms the migration of Zn and Ni during the pyrolysis of the RuNi@ZIF-8 precursor, providing definitive evidence of atomic replacement. Due to the synergistic influence of RuZn nanocrystals and Ni-CN, the resulting (RuZn)/Ni-CN multisite catalyst exhibited superior hydrogen evolution reaction (HER) ability compared to the conventional nanoalloy-based catalysts. Density functional theory calculations revealed that the integration of the (RuZn)n cluster on Ni surrounded with different N-coordinated carbon structures enhanced HER activity with the optimized (RuZn)n/NiN2C2 catalyst exhibiting a low ΔGH and improved electron charge redistribution, thereby promoting favorable hydrogen adsorption. Our findings provide valuable insights into the design and optimization of photocatalysts through atomic-level engineering, opening new avenues for efficient and sustainable energy conversion technologies.
