Butyrylcholinesterase: An economical marker of disease activity in oral squamous cell carcinoma before and after therapy.

INTRODUCTION: Biomarkers which can predict disease progression and serve as prognostic indicators are necessary for better management of oral cancer. Studies have shown that Cholinesterase plays an important role in cellular proliferation, differentiation and may have a possible involvement in tumor growth. AIM AND OBJECTIVE: The present study is aimed to determine the utility of serum Butyrylcholinesterase (BChe) levels as a marker for progression of oral squamous cell carcinoma (OSCC) in relation to the grade of the tumor and to determine if any variation occurred in the levels of BChe before and after therapy. MATERIALS AND METHODS: A total of 120 patients were included in the study and divided into two groups as Group A-30 patients (healthy individuals) and Group B-90 cases of histopathologically diagnosed OSCC. The blood sample was collected before surgery, re-collected after the completion of radiotherapy (i.e., 3 and 6 months postsurgery) and analyzed biochemically for the concentration of BCh. STATISTICAL ANALYSIS: Paired t-test, ANOVA, and post hoc test (Bonferroni) were used for determining the statistical significance. RESULTS: BChe levels were lower in OSCC (2940.32-1405.50 u/l when compared with controls (11149.60-11243.07 unit/l) and this difference was statistically significant. Postoperatively at 3 months, the serum BChe levels of OSCC patients increased almost two-fold compared to the preoperative values, and this difference was also statistically significant (P = 0.000) After 6 months, these levels further increased but did not reach those of controls. CONCLUSION: BChe can be used as an inexpensive, easy to use, noninvasive biomarker for the evaluation of disease-free survival in OSCC patients.

A Case of Post Encephalitic Optic Neuritis: Clinical Spectrum, Differential Diagnosis and Management.

PURPOSE: Most cases of optic neuritis are idiopathic or are associated with multiple sclerosis. We present a case in which a young female developed post-infectious left optic neuritis following herpes simplex encephalitis (HSE). CASE REPORT: A 24-year-old female presented with a severe headache, fever, and malaise of a one-week duration. Viral encephalitis was diagnosed and treated; intravenous acyclovir (750 mg every 8 h) was administered for 14 days. The patient improved clinically and was prescribed oral valacyclovir (1,000 mg, three times daily) for an additional 3 months as an outpatient. The patient presented again four weeks after the initial admission with left periocular pain and other typical manifestations of optic neuritis. We diagnosed post-infectious left optic neuritis following viral encephalitis. Corticosteroid therapy with 250 mg intravenous methylprednisolone every 6 hours was initiated and the patient showed rapid significant recovery. CONCLUSION: This case report highlights the patient's clinical course and includes a brief history of the systemic effects of HSE, as well as the pathophysiology, management, and differential diagnosis of post-encephalitic optic neuritis. We suggest that clinicians should routinely perform an ophthalmologic examination during the follow-up visits of such patients.

A case report on total pancreatic lipomatosis: An unusual entity.

Total pancreatic lipomatosis (PL) is an unusual entity of pathologic significance and speculative origin. It refers to complete replacement of pancreatic parenchyma by fat cells. Fat replacement may vary from mild fatty infiltration to massive replacement of the pancreas by adipose tissue, resulting in malabsorption syndrome due to pancreatic insufficiency. We present a case of a 60-year-old elderly woman with atypical abdominal complaints, diabetes mellitus, weight loss, and steatorrhea. Abdominal computed tomograms were diagnostic of PL. Magnetic resonance imaging verified this impression. The patient improved clinically after the 8-week trial of high-dose oral pancreatic enzyme replacement therapy. There is a marked reduction of steatorrhea and weight gain. This case report focuses on pathophysiology, diagnosis, and treatment guidelines of PL.

Comparative Evaluation of Platelet Rich Fibrin and Dehydrated Amniotic Membrane for the Treatment of Gingival Recession- A Clinical Study.

INTRODUCTION: The main objective of any therapeutic intervention aimed at root coverage is to restore the tissue margin to the cemento-enamel junction and to regenerate the lost periodontium. AIM: To compare the effectiveness of Platelet Rich Fibrin (PRF) and Amniotic Membrane (AM) in the treatment of gingival recession by Coronally Advanced Flap (CAF) Technique. MATERIALS AND METHODS: Thirty systemically healthy patients who met inclusion-exclusion criteria were selected. After Phase-I therapy, patients were randomly allocated to one of the groups; PRF (Group-A) and Amnion Group (Group-B). Clinical parameters like Plaque Index (PI), Recession Depth (RD) and Width of Keratinized Gingiva (WKG) were measured on the baseline day, three months and six months postoperatively. Mann-Whitney test and Wilcoxon signed ranks test were applied for intergroup and intragroup comparisons respectively. RESULTS: Intergroup comparison between platelet rich fibrin and amniotic membrane showed statistically insignificant difference in the recession depth and width of keratinized gingiva at three and six months postoperatively. CONCLUSION: Both the membranes were equally effective in terms of recession coverage and increase in width of keratinized gingiva.

Deep Orbital Dermoid Cyst Bulging into the Superior Orbital Fissure: Clinical Presentation and Management.

PURPOSE: To present a case of deep orbital dermoid cyst with emphasis on clinical presentation, imaging spectrum, differential diagnosis and management. CASE REPORT: A 28-year-old female was referred to our hospital with chief complaint of drooping of right eyelid and progressive headache. Ocular motility, visual acuity and fundus examination were normal. computed tomography (CT) and magnetic resonance imaging (MRI) revealed a well-defined, intraosseous deep orbital dermoid cyst (5.9 mm × 12.5 mm) located near the apex of right orbit, extending from greater wing of sphenoid into the superior orbital fissure. Due to occulomotor nerve (superior and inferior divisions) compression which passes through the superior orbital fissure, ipsilateral headache and ptosis occurred. Complete surgical excision of cyst was performed using noninvasive extracranial lateral orbitotomy approach. After removal of the cyst, curette and cutting drill were used to thoroughly remove any residual cystic content. Histopathological analysis confirmed the diagnosis. The healing was uneventful postoperatively. CONCLUSION: CT and MRI are easy, reliable, safe and effective imaging methods for establishing the diagnosis of orbital dermoid cyst. Size, location and manifestations are the most important determinants of the disease management. Complete surgical excision without rupture of the cyst is the treatment of choice.

The Comparative Evaluation of Patient's Satisfaction and Comfort Level by Diode Laser and Scalpel in the Management of Mucogingival Anomalies.

BACKGROUND: Surgical correction of mucogingival anomalies is required to enhance patient's compatibility to maintain oral hygiene or to improve facial aesthetics or both. Laser has become a desirable and dependable alternative for traditional surgical techniques because it is simple and painless with more predictable outcomes. AIM: The aim of this study was to compare the effects of the conventional scalpel technique and the laser technique on the degree of discomfort, satisfaction, healing and postoperative pain experienced by patients after correction of mucogingival anomalies. MATERIALS AND METHODS: In the present study 70 patients were enrolled and randomly distributed in two groups i.e. surgical correction of mucogingival anomalies by scalpel and by laser. Patient's comfort level, pain and satisfaction level was assessed by using Visual analogue scale (VAS) and healing was evaluated by healing index. RESULTS: The results indicated patients treated with the diode laser had less postoperative pain and discomfort with remarkable satisfactory results and healing compared to patients treated with the conventional technique. CONCLUSION: Laser is a desirable therapeutic alternative to correct soft tissue anomalies. It allows good control of haemorrhage with comfortable healing phase and appreciable satisfactory outcomes.

Impact of Bariatric Surgery and Diet Modification on Periodontal Status: A Six Month Cohort Study.

BACKGROUND: Nutrition is an essential component of oral health and improper nutrition is an important aetiological factor in the development of obesity as well. AIMS AND OBJECTIVES: This study aimed to evaluate effect of diet modification and oral hygiene maintenance after bariatric surgery on the periodontal status of Class III and IV obese patients. MATERIALS AND METHODS: Two hundred and twenty four patients between the age ranges of 18 -64 years, from both sexes, were subjected to complete periodontal examination prior to bariatric surgery and 6 months post surgery. Patients were advised diet modification which included more fibrous food intake & decreased intake of soft and sugary food along with supragingival scaling & oral health care regime after bariatric surgery with a 6 month follow up. No periodontal surgical intervention was performed. RESULTS: The patients showed a mean differences in the bleeding score, plaque and gingival index which was found to be statistically significant (p<0.001). The improvement in clinical attachment level and probing pocket depth before and after surgery were found to be statistically insignificant (p>0.05). CONCLUSION: Thus we conclude that fibrous diet along with good periodontal care can help to improve the oral hygiene status of patients undergoing bariatric surgery, even if periodontal surgical intervention is not performed resulting in freedom from periodontitis, thus improving quality of life of the patient.

Assessment of postoperative pain of oral mucosal biopsy: A health initiative prospective study.

OBJECTIVES: The aim of the present study was to evaluate post-biopsy pain using a questionnaire supported by a visual analog scale (VAS), and the role of pharmacological agents in pain relief. METHOD AND MATERIALS: Three hundred patients undergoing oral biopsy were included in the study and divided into three groups. Group A: Patients received no analgesic post biopsy, except when required (SOS). Group B: Patients received anesthetic mouthwash along with oral analgesic post biopsy. Group C: Patients received anesthetic mouthwash alone. The statistical analysis was done using statistical analysis software SPSS version 11.0. ANOVA was used to compare the VAS scores and hygiene status of the three groups, while Pearson's chi-square test was used for determining association between age, sex, educational status, and association of pain with biopsy site. RESULTS: A highly significant difference was found between the VAS scores of patients in Groups A, B, and C, and significant correlation was observed between hygiene status and degree of pain. CONCLUSION: Oral biopsy is definitely associated with pain, if proper medications are not deployed. Anesthetic mouthwash alone is sufficient to relieve the pain produced by oral biopsy. Direct correlation exists between hygiene status and the level of discomfort, thereby indicating that pain control is essential for good oral hygiene maintenance.

Peripheral cemento-ossifying fibroma: A case report with review of literature.

Peripheral cemento-ossifying fibroma (PCOF) is a rare osteogenic neoplasm that ordinarily presents as an epulis-like growth. This is of a reactive rather than neoplastic nature and its pathogenesis is uncertain. PCOF predominantly affects adolescent and young adults with greatest prevalence around 28 years. We report here a rare clinical case of PCOF of the mandible, 1 cm mesiodistally and 1.5 cm occluso-gingivally in diameter, which caused difficulty in eating and speech, in a 42-year-old female patient. She was asymptomatic for 1 year and on follow-up for 6 mo post surgically showed gingival health and normal radioopacity of bone without any recurrence. Clinical, radiographic and histological characteristics are discussed and recommendations regarding differential diagnosis, treatment and follow up are provided. The controversial varied nomenclature and possible etiopathogenesis of PCOF are emphasized.

Field cancerization: concept and clinical implications in head and neck squamous cell carcinoma.

Cancer begins with multiple cumulative epigenetic and genetic alterations that sequentially transform a cell or a group of cells in a particular organ. The early genetic events might lead to clonal expansion of pre-neoplastic daughter cells in a particular tumor field. Subsequent genomic changes in some of these cells drive them towards the malignant phenotype. These transformed cells are diagnosed histopathologically as cancers owing to changes in cell morphology. Conceivably, a population of daughter cells with early genetic changes (without histopathology) remains in the organ, demonstrating the concept of field cancerization. The concept of "field cancerization" was first introduced by Slaughter et al in 1953 when studying the presence of histologically abnormal tissue surrounding oral squamous cell carcinoma. It was proposed to explain the development of multiple primary tumors and locally recurrent cancer. With present technological advancement and carefully designed studies using appropriate control tissue will enable identification of important molecular signatures in these genetically transformed but histologically normal cells. Such tumor-specific biomarkers should have excellent clinical utility. This review examines the concept of field cancerization in head and neck cancer and its possible utility in early detection, tumor progression and clinical significance.

The effectiveness of enamel matrix protein (Emdogain(®)) in combination with coronally advanced flap in the treatment of multiple marginal tissue recession: A clinical study.

BACKGROUND: Gingival recession resulting in root exposure is a common problem faced by clinicians. This clinical study compared the results obtained by treating gingival recession using enamel matrix derivative (Emdogain gel(®)) along with coronally positioned flap and coronally positioned flap alone. MATERIALS AND METHODS: Twenty patients with a total of 46 gingival recession defects, each patient with a minimum of two recession defects, were included in the study. The test group, which consisted of 10 patients with 22 recession defects, was treated by enamel matrix derivatives (Emdogain gel) in combination with a coronally positioned flap, while the control group, which consisted of 10 patients with 24 gingival recession defects, was treated with 24% ethylenediaminetetraacetic acid (EDTA; Prefgel(®)) in combination with coronally positioned flap. RESULTS: Student's paired and unpaired t-test was used for statistical analysis. If the probability value (P) was less than 0.05, it was considered significant. Data from this study demonstrated that application of (EMD) Emdogain gel resulted in a statistically significant increase in root coverage, gain in the clinical attachment level (CAL), and probing pocket depth (PPD) reduction when compared with coronally advanced flap (CAF) alone, but there was no statistically significant difference in the width of keratinized gingiva (WKG) between the two groups.

Correlation of serum levels of vascular endothelial growth factor with TNM staging, histopathologic grading, and surgical therapy for oral squamous cell carcinoma.

OBJECTIVE: This study aimed to assess the serum levels of vascular endothelial growth factor in oral squamous cell carcinoma patients before and after surgical therapy, to compare these values with those of healthy individuals using ELISA, and to evaluate if any correlation existed between vascular endothelial growth factor levels and TNM stage or histolopathologic grade of the tumor. METHOD AND MATERIALS: The study included three groups: group A1 consisted of 31 oral squamous cell carcinoma patients who had not received any prior treatment; group A2 consisted of the same 31 oral squamous cell carcinoma patients who had undergone radical surgical excision 1 month prior but no adjuvant therapy; and group B (control group) consisted of 16 healthy individuals. The serum vascular endothelial growth factor levels were assessed using the ELISA kit. RESULTS: The vascular endothelial growth factor levels of preoperative oral squamous cell carcinoma patients were found to be three times higher than those of controls, and this difference was found to be statistically significant. The postoperative vascular endothelial growth factor levels had decreased 1 month after surgery but did not decrease to baseline levels. The vascular endothelial growth factor levels increased progressively with the TNM stage and histologic grade of tumor, but no definite correlation between the two could be found. CONCLUSION: Vascular endothelial growth factor is an important marker of angiogenesis, as the vascular endothelial growth factor levels of the oral squamous cell carcinoma groups remained significantly elevated compared to that of controls. Though no significant difference was found between the pre- and postoperative oral squamous cell carcinoma groups, it can be suggested that successful treatment may reduce serum vascular endothelial growth factor levels if the time period of postoperative sample collection is increased. Only then can the utility of vascular endothelial growth factor as marker for assessing the effectiveness of surgical therapy or as a prognostic indicator be commented upon.

Serum alkaline phosphatase: a potential marker in the progression of periodontal disease in cirrhosis patients.

OBJECTIVE: As a consequence of their liver dysfunction, cirrhotic patients have elevated levels of serum alkaline phosphatase (ALP). Increased ALP activity is seen in periodontal tissues during the progression of periodontitis. The present study was carried out to compare ALP levels in cirrhosis patients with and without periodontitis and to correlate ALP levels with the severity of periodontitis. METHOD AND MATERIALS: Both the test and control groups consisted of 30 liver cirrhosis patients with or without periodontitis. The parameters recorded were modified OHI-S Index, Gingival Index (GI), and clinical attachment level (CAL). All patients underwent standardized panoramic radiographs to assess alveolar bone height. The total serum ALP was determined with the kinetic method (R.A 50). RESULTS: Alveolar bone loss (ABL) was 1.62 ± 0.32 mm in the test group and 0.28 ± 0.04 mm in the control group. Mean clinical attachment level (CAL) for the test group was greater than the control group: 2.34 ± 0.67 mm and 0.43 ± 0.14 mm, respectively. The mean serum alkaline phosphatase level in the test group was higher (39.94 ± 3.34) than the control group (29.42 ± 6.11) and the differences was statistically significant (P > .05). When comparison was made between age group (20 to 40 years and 41 to 60 years), the older age group liver cirrhosis patients exhibited significantly higher values for bone loss, clinical attachment level, and serum ALP level. CONCLUSION: There is strong positive correlation between periodontal breakdown and serum alkaline phosphatase level in liver cirrhosis patients.
