Clinical Outcomes of ULTRA EZY Bar vs Erich Arch Bar in Conservative Management of Maxillofacial Fractures: A Randomized Controlled Trial.

Objective: Various techniques have been employed from time to time to achieve maxillomandibular fixation, and arch bars provide an effective and versatile means of maxillomandibular fixation, and however, some of the issues occurring with it have been eliminated with the introduction of Ultralock EZY bar. The aim of the present study is to compare the advantages and disadvantages of Ultralock Ezy bar over the Erich arch bar in mid-face fracture or maxillary fracture or mandibular fracture or both requiring conservative treatment. Materials and Methods: A total of 20 patients reported to the Department of Oral and Maxillofacial Surgery in Sudha Rustagi Dental College and Hospital, Faridabad, with mid-face fracture/maxillary fracture, mandibular fracture or both. The treatment plan required intermaxillary fixation. As a part of treatment plan, group was selected randomly divided into 20 arches in each group that is test arch group and control arch group.Test arch group included arches in which Ultralock EZY bar was done. Control arch group included arches in which Erich arch bar was done. The parameters compared in both the groups were surgical time taken, injuries due to wires, arch bar stability, oral hygiene index, patient acceptance and comfort, pulp vitality, and complication (if any). Results: The average surgical time taken was less, and oral hygiene status and patient acceptance were better in test group. There was not much statistically significant difference in pulp vitality but number of cases with absence of pulp vitality were more in test group. Conclusion: This study emphasizes the use of Ultralock Ezy bar as a quick and easy method than Erich arch bar. Oral hygiene maintenance was comparatively better in patients with Ultralock Ezy bar than those with Erich arch bar. For the patients who require long-term IMF, Ultralock Ezy bars can be a viable option.

Incidence and Clinical Presentation of Temporo-Mandibular Joint Disorders and their Association with Psychological Distress and Para-Functional Habits in a Non-Patient Population.

Purpose: The study aims at finding the incidence of temporo-mandibular joint disorders (TMDs) in a non-patient population and relates their association with psychological distress and parafunctional habits. Materials and Methods: A DC/TMD questionnaire and DASS-21 scale survey were completed by selected participants followed by clinical examination of TMDs symptoms in sample population. Results: A study sample of 855 participants revealed 36.65% population with various TMDs symptoms, while 63.5% population had no TMDs symptoms. 50.8% study participants were men, and 49.2% were women. Of all affected population, 16.2% had pain-related TMDs, 12.39% had intra-articular TMDs symptoms, and 8.07% had TMJ pain associated with pain or dysfunction. For all TMDs symptoms groups, the strongest correlations were for depression, while no significant associations were observed with parafunctional habits in all groups. Conclusions: Overall psychological distress and anxiety increased the prospects of TMDs symptoms. Clinical factors like muscle tenderness, crossbite and deep vertical overlap seem to be significant etiological factors, while angle molar relationship and parafunctional habits do not seem to be significant etiologic factors in TMDs.

Minimally traumatic extraction techniques in nonrestorable endodontically treated teeth: A comparative study.

Aim: The goal of this study was to assess the effectiveness of piezotome as compared to periotome extractions of nonrestorable endodontic treatment of teeth in terms of operational time, pain control, and postoperative bone loss considering the prosthetic rehabilitation in future. Materials and Methods: A double-blind, randomized controlled trial was conducted with 100 patients who wanted single-rooted teeth to be extracted (which failed endodontically). The participants have been randomized into two equal groups named as - (i) a periotome group (ii) and a piezotome group. Duration of the surgery, postoperative pain within 7 days, complications (if any) associated with the extraction process were performed as a part of clinical assessment. Bone loss has been analyzed 6 months after the surgery radiographically. The data have been recorded and analyzed using the version 22.0 of the SPSS software package. Results: All parameters in the periotome category (P < 0.05) were statistically significant except for bone loss and gingival laceration in comparison to piezotome group. In the piezotome group, a longer time was observed for surgery and delayed pain control was achieved. In our study, we found statistically significant more marginal bone loss in piezotome group in comparison with periotome group. Conclusion: The findings of this study indicate that for intraoperative and postoperative comfort periotome could be used as a safer and cheaper option for atraumatic extractions but piezosurgery may prove as a better choice soon for surgeries in the maxillofacial region to maintain soft-tissue integrity.

UBA1 and DNMT3A mutations in VEXAS syndrome. A case report and literature review.

Vacuoles, E1 enzyme, X linked, autoinflammatory, somatic (VEXAS) syndrome is a recently described X-linked autoinflammatory condition associated with somatic mutation of the ubiquitin-like modifier activating enzyme 1 (UBA1) gene. It often coexists with myelodysplastic syndrome, which can occur due to DNA (cytosine-5)-methyltransferase 3A (DNMT3A) mutation. These patients, predominantly males, present after the fifth decade of life with unique systemic inflammatory clinical features and have haematological abnormalities and vacuolated precursor cells on bone marrow pathology. Here we describe a unique case of VEXAS syndrome in a patient harbouring DNMT3A gene mutation with coexisting UBA1 mutation with a review of literature.

Association of serum sialic acid concentration with diabetic complications and cardiovascular risk factors in an Indian population.

INTRODUCTION: Sialic acid (SA) is an acetylated product of neuraminic acid. It acts as a cofactor of many cell surface receptors (e.g. insulin receptors) and is positively associated with most of the serum acute phase reactants. Sialic acid is an important component of serum, which is elevated in diseases such as diabetes and certain malignancies. Diabetes mellitus (DM) is associated with an increase in SA concentration along with other complications. The present study was undertaken to assess the relationship between serum SA and type 2 diabetes. MATERIAL AND METHODS: A total of 200 type 2 DM patients, 145 males and 55 females, were included in the study. Also, 100 healthy individuals served as the control group. Parameters assessed included serum SA, lipid profile, urine microalbumin, LDL-C, lipoprotein(a), and serum fibrinogen. The relationship between serum SA and diabetic complications viz retinopathy, nephropathy, and neuropathy was also assessed. RESULTS: Type 2 DM patients had significantly higher levels (p < 0.01) of SA (77.35 ±4.6 mg%) as compared to the control group (68.23 ±7.9 mg%). Increased levels of serum SA were seen in patients with diabetic nephropathy and retinopathy. No correlation was seen between serum SA and diabetic neuropathy. CONCLUSIONS: Elevated serum SA concentration is significantly related to type 2 DM and associated cardiovascular risk factors. Further study of acute-phase response markers and mediators as indicators or predictors of diabetic microvascular complications is therefore justified.

Metastatic Carcinoma of Prostate as a Mimicker of SAPHO Syndrome.

Paraneoplastic arthritides are a group of immune-mediated inflammatory arthropathies associated with occult or manifest malignancy. Musculoskeletal spread of an underlying malignancy may also mimic many rheumatologic conditions. Distinguishing primary rheumatologic condition from paraneoplastic arthritides versus direct musculoskeletal spread of malignancy can be challenging especially in individuals with prior history of cancer and new musculoskeletal complaints. SAPHO (synovitis, acne, pustulosis, hyperostosis and osteitis) syndrome is an uncommon, although under recognized autoimmune disorder. Two musculoskeletal manifestations, namely inflammatory osteitis and hyperostosis of anterior chest wall with or without dermatologic manifestations, constitute a unifying feature of SAPHO syndrome. However, diagnosis of SAPHO syndrome is one of exclusion, and a wide variety of disorders including infections, malignancy (chondrosarcoma/osteosarcoma/metastasis), metabolic bone disorders (Paget's disease), osteoarthritis, seronegative spondyloarthropathy (spA) and osteonecrosis form part of a broad differential diagnosis. We present the case of a man, aged 72 years, with signs and symptoms of SAPHO syndrome and skin findings. Detailed history, radiological imaging, dermatology appearance, and role of immunohistochemical markers, especially staining for NKX3.1 protein with a novel antibody, led to a diagnosis of metastatic prostate adenocarcinoma. To our knowledge, this is the first case of metastatic adenocarcinoma of the prostate manifesting as SAPHO syndrome and cutaneous metastasis.

Percutaneous catheter drainage of uncomplicated amoebic liver abscess: prospective evaluation of a clinical protocol for catheter removal and the significance of residual collections.

INTRODUCTION: Patients with amoebic liver abscess (ALA) may require percutaneous catheter drainage (PCD). Once the PCD output is substantially reduced or has ceased along with clinical recovery, residual collections on radiological evaluation may concern the treating physicians. The prevalence and significance of such collections is unknown, and the subsequent approach how to tackle them is unclear. METHODS: Consecutive patients with one or more uncomplicated ALAs requiring drainage were prospectively enrolled from 3 hospitals and managed based on a standard approach. Catheter removal was attempted after the patients fulfilled all 4 of the following criteria: disappearance of abdominal pain, absence of fever for at least 48 h, an improving trend of TLC (documented on 2 consecutive reports), and catheter drain output of < 10 ml/day for at least 2 consecutive days. RESULTS: A total of 110 patients (mean age 46.6 ± 10.5 years, 93.6% males, 89.1% alcoholics) underwent PCD placement; 69 patients (69/110; 62.7%) met all 4 criteria within 5 days of PCD placement (optimal response) and had an uncomplicated course. Patients with suboptimal responses (41/110; 37.3%) were evaluated for local and systemic complications; the appearance of fresh collections (5/110; 4.5%), abscess rupture (2/110; 1.8%), bile leakage (3/110; 2.7%), cholangitis (2/110; 1.8%), thrombophlebitis (2/110; 1.8%) and hospital-acquired infections (2/110; 1.8%) were diagnosed and treated accordingly. Ultimately, PCD removal (based on the fulfilment of all 4 criteria) was universally successful after a median of 5 days (IQR, 4-9 days). None of the patients had symptom recurrence after PCD removal, although residual collections were still seen in 97.3% of patients at the time of PCD removal and in 92.1% and 84.9% of patients available for follow-up at 1 and 3 months, respectively. CONCLUSION: Based on our clinical protocol, PCD removal in ALA can be successfully expedited even in the presence of residual collections. An inability to fulfill all 4 criteria within 5 days of PCD placement warrants further evaluations for local and systemic complications that require additional therapeutic measures.

Mesenteric panniculitis in a patient with new onset dermatomyositis.

Mesenteric panniculitis (MP), part of the spectrum of sclerosing mesenteritis, is an often asymptomatic disorder that is characterised by chronic inflammation of abdominal mesentery. We present a case of an 83-year-old woman who presented with proximal muscle weakness and erythematous, photosensitive rash of the face and upper torso and was subsequently diagnosed with dermatomyositis based on skin biopsy, electromyography and muscle biopsy. She had radiographic evidence of panniculitis on CT scan of the abdomen and pelvis for malignancy surveillance, which improved on serial CT scan 3 months after beginning treatment for her underlying dermatomyositis with prednisone and mycophenolate mofetil. Our case highlights that MP can be associated with underlying autoimmune disease. Connective tissue disease could be considered in the differential of MP when other etiologies such as surgery, trauma and malignancy are ruled out.

Evaluation of Alveolar Ridge Height Gained by Vertical Ridge Augmentation Using Titanium Mesh and Novabone Putty in Posterior Mandible.

AIM: The purpose of this case series was to report the clinical and radiographical outcomes of vertical ridge augmentation in edentulous posterior mandible using a combination of titanium mesh with novabone putty. MATERIAL AND METHOD: Twenty patients were included, and grafting was done using alloplastic novabone putty supported by titanium mesh as the barrier for guided bone regeneration. RESULTS: Sixteen patients exhibited good soft tissue healing. Postoperative flap dehiscence occurred relatively early in the healing period in one patient followed by graft extrusion and delayed healing in other three patients. The mean vertical height of augmented bone was 4.825 ± 1.1387 mm. CONCLUSION: This report demonstrates the remarkable efficacy of guided bone regeneration using a combination of titanium mesh and novabone putty for vertical ridge augmentation, thus expanding the indications for implant therapy and allowing recovery of the three-dimensional esthetic architecture in a severely resorbed alveolar ridge.

Experience with Anterior Maxillary Osteotomy Techniques: A Prospective Study of 20 Cases.

AIM: This prospective study aimed at studying the complications associated with different techniques of anterior segmental maxillary osteotomy. MATERIAL AND METHOD: The study was conducted on 20 cases diagnosed with anteriorly prognathic maxilla with class 1 molar relation. The patients were followed up for a period of at least 1 year. The clinical and demographic data along with the intraoperative and postoperative complications associated with different treatment techniques were recorded. RESULTS: In five cases, Wassmund technique was followed with average time span of 32 min. Wunderer and Cupar technique took average time span of 23 min. Two patients presented with four non-vital teeth in a follow-up period of 1 year and one patient treated with Cupar's technique had complication of palatal tear. Only one patient reported with relapse in a follow-up period and none of the patients had any complication associated with hemorrhage, neurosensory alteration or requiring plate removal. The findings of our study recommend ASMO as treatment modality of choice in patients with bimaxillary and/or dentoalveolar protrusion with Cupar's technique providing more ease of operation.

Pain Control by Novel Route of Gifted Choice Against Peroral Route.

INTRODUCTION: Pain after surgical extraction of third molars has been a nemesis for oral surgeons with clinicians, thus striving for an analgesic modality. NSAIDs are among the most widely used therapeutic classes of analgesics. Transbuccal diclofenac sodium patches have been developed as an innovative drug delivery system using buccal mucosa as a gifted choice, hence overcoming first pass metabolism and offering the advantage of sustained drug delivery with reduced incidence of systemic adverse effects. AIM: A comparative study was conducted to evaluate the efficacy of diclofenac sodium for pain control, administered via the far-fetched and gifted novel route through the transbuccal patch and by ever popular per oral route and also to assess the adverse effects vis-à-vis for transbuccal diclofenac patch and oral diclofenac following extraction of bilaterally symmetrical impacted mandibular third molars under local anaesthesia. METHODOLOGY: Thirty healthy subjects of both the sexes in the age of 12 to 50 years with asymptomatic bilaterally symmetrical mandibular third molars underwent extraction under LA. It is a split-mouth study, i.e. after the extraction of tooth on one side, diclofenac sodium (50 mg) via oral route was given and then in another visit, when the same patient is comfortable and asymptomatic, extraction on contralateral side was executed and transbuccal patched diclofenac sodium (20 mg) was applied. Pain was measured on visual analog scale and verbal rating scale by the patient for 3 days and adverse effects if any were noted. RESULT: Statistical analysis showed that transbuccal diclofenac sodium was significantly efficacious when compared to the drug administered orally. Also, statistically significant results were obtained in percentage reduction in pain from 1st to 3rd postoperative day in transbuccal group. No significant difference is seen for adverse reactions. CONCLUSION: Transbuccal diclofenac sodium patch is more efficacious and can be used for pain control.

Hemangiopericytoma of Gingiva in a 4-Year-Old Child: A Rare Case Report.

A hemangiopericytoma is a type of soft tissue sarcoma that originates in the pericytes in the walls of capillaries which was characterized in 1942. It is commonly seen in the age group of 5th-6th decades of adults and only 5-10% of cases occur in children with extreme rare occurrence in head and neck region (16%). A rare case of hemangiopericytoma in a 4-year-old female patient is presented here and its clinical, histopathological and immunohistochemically features are discussed. Though surgical resection remains the mainstay, excisional biopsy was primarily performed to reach the final diagnosis. Even in the follow-up phase of 1 year, no recurrence or no metastatic changes were observed.

Treatment of Keratocystic Odontogenic Tumours: A Prospective Study of 30 Cases.

AIM: This prospective study aimed at presenting different treatment modalities and its association with the recurrence rate of KCOT. MATERIAL AND METHOD: The study was conducted on 30 patients diagnosed with KCOT between March 2009 and 2012. The patients were followed up for a period of at least 1 year. The clinical, radiographic and demographic data were recorded and four different treatment modalities were followed to assess the recurrence of the tumour. RESULTS: In the study, KCOT showed male predominance with a male: female ratio of 23:7. Of the total cases, 26 (86.67 %) patients had parakeratinised KCOT and the rest 4 (13.3 %) patients had orthokeratnised KCOT. Nine (30 %) patients were reported with recurrence of the tumour within 1-2 years of surgery-all these patients had parakeratinised cyst. Recurrence was observed in four (50 %) out of eight cases of marsupialisation and four (44.44 %) out of nine cases of treatment using the enucleation process. No recurrence was seen in patients treated with resection; however only one out of three patients treated with enucleation, followed by fixation with Carnoy's solution showed signs of recurrence. The histopathological examination determined the aggressive nature of KCOT and its association with the recurrence rate as well. The findings of our study indicate that more aggressive treatment can aid in reducing the chances of recurrence.

Engineering multivalent antibodies to target heregulin-induced HER3 signaling in breast cancer cells.

The use of antibodies in therapy and diagnosis has undergone an unprecedented expansion during the past two decades. This is due in part to innovations in antibody engineering that now offer opportunities for the production of "second generation" antibodies with multiple specificities or altered valencies. The targeting of individual components of the human epidermal growth factor receptor (HER)3-PI3K signaling axis, including the preferred heterodimerization partner HER2, is known to have limited anti-tumor effects. The efficacy of antibodies or small molecule tyrosine kinase inhibitors (TKIs) in targeting this axis is further reduced by the presence of the HER3 ligand, heregulin. To address these shortcomings, we performed a comparative analysis of two distinct approaches toward reducing the proliferation and signaling in HER2 overexpressing tumor cells in the presence of heregulin. These strategies both involve the use of engineered antibodies in combination with the epidermal growth factor receptor (EGFR)/HER2 specific TKI, lapatinib. In the first approach, we generated a bispecific anti-HER2/HER3 antibody that, in the presence of lapatinib, is designed to sequester HER3 into inactive HER2-HER3 dimers that restrain HER3 interactions with other possible dimerization partners. The second approach involves the use of a tetravalent anti-HER3 antibody with the goal of inducing efficient HER3 internalization and degradation. In combination with lapatinib, we demonstrate that although the multivalent HER3 antibody is more effective than its bivalent counterpart in reducing heregulin-mediated signaling and growth, the bispecific HER2/HER3 antibody has increased inhibitory activity. Collectively, these observations provide support for the therapeutic use of bispecifics in combination with TKIs to recruit HER3 into complexes that are functionally inert.

Rare occurrence of lobular capillary hemangioma on the palate: possible mechanism and treatment considerations.

Lack of striking clinical presentation makes the diagnosis of vascular lesions a difficult task. There lies a great probability that a case of capillary hemangioma at a rare location like the palate in a pregnant female might be misdiagnosed. Definitive diagnosis can only be made after thorough clinical and histopathological examination. Additional care needs to be exercised in a pregnant female while treating any tumor-like growth, including maintenance of diet and oral hygiene. We present one such case of capillary hemangioma of the palate in a pregnant female, along with treatment considerations.

Relevance of anterior mandibular body ostectomy in mandibular prognathism.

PURPOSE: We tried to find out the relevance of anterior mandibular body ostectomy in deformities of the mandible specially prognathism, which is primarily limited to anterior part only. PATIENTS AND METHODS: Ten patients with skeletal deformity along with malocclusion, which was limited to anterior body of mandible were selected. Selected patients had proper molar interdigitation (even if class 3) and in general had anterior crossbite (except one). All patients had crossed their growth spurts and had no hormonal influence on facial deformity. Specific protocol, including cephelometric analysis cephalometry for orthognathic surgery, prediction tracing and model surgeries were devised. Pre and post-surgical orthodontics and body ostectomy were performed in all patients along with 18-month post-op follow-up. RESULTS: There was significant reduction in prognathism and horizontal dysplasia in all ten patients. Anterior crossbite as well as axis of incisiors over mandibular plane was corrected in all patients due to decrease in length of mandibular body. All patients showed decreased facial height and better lip competence with intact posterior occlusion and no (negligible or transient) sensory loss. CONCLUSIONS: Our study could confirm that people whose deformity is limited to the anterior part of mandible with reasonable occlusion posteriorly can get satisfactory cosmetic and functional results through body ostectomy alone rather than going for surgical procedure in the ramal area, which is liable to cause sensory and occlusal disturbances.

Pilomatrixoma of the arm: a rare case with cytologic diagnosis.

Pilomatrixoma, a benign skin appendageal tumor, is seen commonly in head and neck. Occurrence of pilomatrixoma in the upper extremities is not common and has been reported infrequently in the available literature. Only a few cases with preoperative aspiration cytology have been reported in the literature. A five-year-old girl underwent fine needle aspiration (FNA) of a firm subcutaneous nodule on the lateral aspect of left arm. FNA smears showed scattered and few fragments of round to oval cells along with multinucleated giant cells. Few shadow cells were seen. A cytologic impression of pilomatrixoma was rendered, which was confirmed on histopathology. Pilomatrixoma, a common skin appendageal tumor in head and neck region, should be considered in the cytologic differential diagnoses of subcutaneous masses even in unusual locations like arm. The varied cytomorphology should be remembered to avoid misdiagnosis.

Prevalence of hepatitis C virus in a selected geographical area of northern India: a population based survey.

BACKGROUND AND AIM: Epidemiological data on hepatitis C virus (HCV) infection from India are scanty. We conducted a population-based seroepidemiologic survey to estimate the prevalence of hepatitis C in Punjab state of northern India. METHODS: A house-to-house survey was conducted in a defined population of 26,273 subjects. Information was gathered according to a predesigned questionnaire with socio-demographic characteristics (age, gender and substance abuse), family history of HCV infection, general health status, associated co-infection, immunization history and potential risk factors for HCV transmission. At the time of clinical evaluation, blood was tested for anti-HCV and those found positive were tested for HCV RNA. RESULTS: Among 5,258 subjects screened, 272 were found to be anti-HCV positive (prevalence rate of 5.2 %); highest prevalence being noticed in 41-60 years age group. Anti-HCV positive rate were not different among males and females. Sixty-seven subjects (1.3 %) were found to be HBsAg positive; four of these being co-infected (5.9 %). Various risk factors for acquiring HCV infection identified were history of surgery, dental treatment and unprotected sex. Other associations were strong family history of HCV positivity, alcohol consumption and diabetes mellitus. CONCLUSION: Chronic HCV infection is a major health problem in Punjab; it appears to be more common than HBV infection. Exercising safe health care related procedures should be emphasized in our country as main modes of transmission of infection identified were related to these.
