Clinicopathological Profile of Nodular Hidradenoma: A ten year Study in a Tertiary Care Center.

Nodular hidradenoma is a rare skin adnexal tumor of eccrine differentiation with predominant site being scalp and axillae. Due to its variable locations and unusual clinical presentation and no definite radiological criteria, histopathology seems to be the mainstay in diagnosing these tumors. Most of the lesions present as a cystic swelling and was clinically thought to be a sebaceous cyst/metastasis/carcinoma/sarcoma. In our study, we have included 37 cases and compared its varied clinical and radiological presentation.

A Comparative Study of Platelet-Rich Fibrin and Platelet-Rich Fibrin with Hydroxyapatite to Promote Healing of Impacted Mandibular Third Molar Socket.

Aim: The purpose of this study was to compare the efficacy of platelet-rich fibrin (PRF) and platelet-rich fibrin (PRF) with hydroxyapatite (HA) on postoperative pain, swelling, soft tissue healing and osseous regeneration in mandibular third molar extraction socket in human patient. Materials and Methods: This prospective study included total 40 patients who reported to the Department of Oral and Maxillofacial Surgery (OMFS), Teerthanker Mahaveer Dental College and Research Centre (TMDC&RC), Moradabad (U.P.). Twenty patients each in both the groups of PRF and PRF with HA were included for the management of impacted mandibular 3rd molar extraction sockets and were evaluated for effectiveness. Evaluation was done on the basis of following parameters pain and swelling at time interval of 1st, 3rd, 7th day, soft tissue healing at time interval of 3rd, 7th, 14th day and osseous regeneration at time intervals of 1st, 3rd, 6th month postoperatively. Results: Pain and swelling were less in the PRF with HA group when compared to PRF group. Soft tissue healing was better in the PRF with HA group compared to the PRF group. The result of the study shows rapid bone regeneration in the extraction socket treated with the PRF with HA group when compared with the PRF group. Also there was less postoperative discomfort in the PRF with HA-treated group. Conclusion: PRF a mitogenic promoter together with a bone graft forms a scaffolding, promotes early healing thus being creating beneficial for the patient and is also economic.

The Significance of Topoisomerase II Alpha in Invasive Breast Carcinoma.

Background Topoisomerase II alpha (Top 2 A) protein has been shown to be a proliferation marker associated with tumour grade. The current study evaluated the prognostic impact of Top 2 A protein on luminal breast cancer and its utility as an independent prognostic marker. Immunohistochemical expression of Top 2 A in breast cancer and its correlation with the tumour type, size, lymph node metastases, grade and ER/PR positivity. Methodology Ethics committee approval was taken and 65 cases of Invasive breast carcinoma presenting to the Department of Pathology at a tertiary care centre in South India were studied. Patient details including age, tumour type, tumour size, tumour grading, estrogen receptor (ER)/progesterone receptor (PR)/human epidermal growth factor receptor 2 (HER2/neu) status and pathologic stage was studied. Immunohistochemistry (IHC) work-up for Top 2 A expression was done and evaluated. Results Of the 65 histological sections of breast cancers, 29/65 showed nuclear positivity for Top 2 A. Node positive tumours 17/65 stained positive for Top 2 A. Stage I tumours 2/65, stage II tumours 12/65 and stage III 14/65 stained positive for Top 2 A. Among the HER2/neu-positive tumours, 22/65 stained for Top 2 A and among ER/PR-positive 9/65 cases were positive for Top 2 A. Triple-negative tumours 5/65 stained for Top 2 A. Conclusion Higher Top 2 A expression was seen in higher stage tumours. HER2/neu-positive tumours significantly showed a correlation with Top 2 A positivity. Therefore, Top 2 A expression can be considered an individual prognostic factor in breast carcinoma.

Relative profiling of L-tryptophan derivatives from selected edible mushrooms as psychoactive nutraceuticals to inhibit P-glycoprotein: a paradigm to contest blood-brain barrier.

Depression is a mental illness and is considered to be a global threat. It is designated as burden of disease. There is therefore an intense need to improve the therapeutic response of antidepressants. India beholds a wide fraction (Agaricus bisporus and Pleurotus ostreatus ) as a vital source of non-hallucinogenic indole compounds. The amino acids L-tryptophan and 5-hydroxytryptophan (5-HTP) are precursors of serotonin. 5-HTP is a potential antidepressant that can cross the blood-brain barrier (BBB) at a high rate and is converted into serotonin more efficiently. Drug delivery across this blockade remains a challenge due to the stimulation of efflux pump receptors called permeability glycoprotein (P-gp). This work reports a comparative phytochemical assay and profiling of non-hallucinogenic tryptophan metabolites using HPLC from two organic extracts of edible mushrooms. The efficacy of the eluted compounds was authenticated as P-gp inhibitors with in vitro and in silico studies. The following four derivatives were obtained from the methanol and ethanol extracts of the mushrooms: 5-hydroxy-L-tryptophan (5HTR), 5-hydroxy tryptamine (5-HT), L-tryptophan (L-Trp), and tryptamine (TA). In vitro and molecular docking studies targeting P-gp (minimum energy: -64.38 and -83.93 kcal/mol, respectively) substantiated the ability of mushroom-derived metabolites to facilitate drug delivery in the brain. This study verified that mushrooms containing non-hallucinogenic metabolites can act as psychoactive nutraceuticals that are significant for enhancing mental health. The high therapeutic efficacy, these mushrooms can serve as ideal neurological drug leads to fortify treatment for mental illness.

Clinical evaluation of Class II and Class III gingival recession defects of maxillary posterior teeth treated with pedicled buccal fat pad: A pilot study.

BACKGROUND: Buccal fat pad (BFP) is a specialized vascular tissue adequately present in buccal space and is close to the maxillary posterior quadrant. The aim of this clinical study was to evaluate the utility of pedicled BFP (PBFP) in the treatment of Class II and III gingival recession. MATERIALS AND METHODS: Ten systemically healthy patients with age ranging from 35 to 55 years with Class II and Class III gingival recession in the maxillary molars were selected. Before the surgical phase, patients were enrolled in a strict maintenance program including oral hygiene instructions and scaling and root planing. A horizontal incision of 1-1.5 cm was made in the buccal sulcus of the maxillary molar region; buccinator muscle was separated bluntly to expose the BFP. The fat was then teased out from its bed and spread to cover defects adequately. It was then secured and sutured without tension. Clinical parameters such as probing depth, recession width, recession length (RL), and width of keratinized gingiva were recorded at baseline and at 6 months postoperatively, and weekly assessment was done at 1 week, 2 weeks, 3 weeks, and after 4 weeks for observations during the postoperative healing. RESULTS: Treated recession defects healed successfully without any significant postoperative complications. Decreased gingival recession horizontal width values from 4.65 ± 0.4327 to 0.94 ± 1.350 and RL from 6.4 ± 1.075 to 0.7 ± 0.6750 were observed postoperatively (P < 0.05). Percentage of root coverage average was 89.3%. There was a statistically significant decrease in the width and depth of recession. CONCLUSION: Pedicled buccal fat showed promising results as the treatment modality in the management of Class II and Class III gingival recession of maxillary posterior teeth.

Effect of Oestrogen on Altering the Serum and Urinary Levels of Calcium, Phosphate and Magnesium in Hysterectomised Women Compared to Natural Menopausal South Indian Women: A Case Control Study.

Given the paucity of studies conducted to know the effect of suddenness and earlier onset of endocrinological changes associated with hysterectomy, on the serum and urinary levels of calcium, magnesium and phosphate the present study was conducted to compare the levels of calcium, magnesium and phosphate in serum and urine of hysterectomised and natural menopausal south Indian women. This is a cross-sectional observational study. The study included three groups of 30 healthy premenopausal, 30 early surgical menopausal and 30 natural post menopausal women. Women suffering from any endocrine disease were excluded. Analysis was performed in serum and urine sample. The levels of calcium, magnesium and phosphate in serum and calcium/creatinine, magnesium/creatinine and phosphate/creatinine ratio were estimated in urine by spectrophotometric method. Hysterectomised women (serum calcium: 8.7 ± 0.09 mg/dl; urine calcium/creatinine: 0.16 ± 0.02) have significantly low serum calcium (p < 0.001) and high urinary calcium/creatinine (p = 0.002) ratio and post menopausal women (serum magnesium: 2.1 ± 0.03; serum phosphate: 4.4 ± 0.16; urinary calcium/creatinine: 0.17 ± 0.02; urinary magnesium/creatinine: 0.09 ± 0.01) have significantly high serum magnesium (p = 0.016), serum phosphate (p = 0.043) and high urinary calcium/creatinine (p = 0.002), magnesium/creatinine ratio (p = 0.025) compared to healthy pre menopausal women. Post menopausal women (serum calcium: 9.1 ± 0.08) have significantly high serum calcium and phosphate compared to hysterectomised women (serum phosphate: 3.93 ± 0.11). Hysterectomised women have significantly low serum calcium, oestrogen and high urinary calcium/creatinine ratio compared to healthy premenopausal women and low serum calcium and low serum phosphate compared to natural postmenopausal women. Natural postmenopausal women had low serum oestrogen and high serum magnesium, serum phosphate, urinary calcium creatinine ratio and urinary magnesium creatinine ratio compared to healthy premenopausal women.

Adolescent Mandibular Central Odontoameloblastoma: A Rare Case Report.

Odontoameloblastoma is a rare odontogenic tumour, characterised by simultaneous occurrence of an ameloblastoma and a compound or complex odontoma in the same tumoral mass. The tumour is seen in first three decades and affects mandible or maxilla equally, commonly found posterior to the canines. The management is similar to unicystic ameloblastoma and odontoma excision. A long term follow up is a must to observe the recurrence. Here we present a rare case of odontoameloblastoma in a 17 year old male, presenting as an asymptomatic anterior mandibular swelling with chief complaint of missing lower front teeth.

Non-traumatic Occulomotor Nerve Palsy: A Rare Case Report and Discussion on Etiopathogenesis.

The ghost of the past has emerged as the horror of today. The fear of weakness/loss of eyesight following extraction is a common thinking amongst the orthodox people of Indian subcontinent. Occulomotor nerve paralysis following dental extraction is a rare complication. Although these ophthalmic complications in routine practice are rare, some time they do occur and pose difficulty to explain. Occulomotor nerve palsy is amongst the rare reported cases of ocular complication. Here we report a case of spontaneous recovery of occulomotor nerve palsy in an elderly diabetic patient and brief discussion on its etiopathogenesis.

Determination of mesiodistal width of maxillary anterior teeth using inner canthal distance.

BACKGROUND: Selection of appropriately sized maxillary anterior teeth is one of the important aspects of complete denture prosthodontics. In the past several methods have been proposed, but little consensus on an effective method for anterior teeth selection has been reached. Inner canthal distance is one of the reliable anatomic dimension that may provide a valid approach to anterior teeth selection. This study was aimed to ascertain the co-relation between inner canthal distance (ICD) and combined mesiodistal width of maxillary anterior teeth. METHOD: This study was conducted in Army Dental Centre (R & R) Delhi Cantonment between Aug 2006 to Mar 2008. Eight hundred dentate Indian subjects of four different ethnic group; Such as Rajputs, Marathas, Sikh and Tamilian. 100 males and 100 females from each race under the age group of 18-30 years formed the subjects of study. The ICD and mesio-distal width of maxillary anteriors were measured using Digital Vernier Caliper. The Data obtained was statistically analyzed. RESULTS: A consistent ratio of 1.61 was found between ICD and combined mesiodistal width of maxillary anteriors in all four ethnic group. The mean value showed no statistically significant difference between sex. The variation in the ratio between the ethnic groups was negligible. CONCLUSION: The findings of the study indicated that, to select the combined mesiodistal width of maxillary anterior teeth, ICD of the required patient should be multiplied by 1.61. This ratio was consistent with all the four ethnic groups irrespective of sex.

The Outcomes of Selective Nerve Root Block for Disc Induced Lumbar Radiculopathy.

INTRODUCTION: Use of Selective Nerve Root Block (SNRB) in lumbar region to relieve radicular pain along the course of a particular nerve is being practiced in the recent past. We observed and tabulated therapeutic outcomes of this procedure in management of radiculopathy induced by a prolapsed disc affecting a particular lumbar nerve root. METHODS: 40 patients with various grades of disc prolapse affecting a particular lumbar nerve root presenting with chronic radicular pain were identified irrespective of age and sex. All were injected with a combination of 40 mg of Methylprednisolone based suspension with local anaesthetic over the affected nerve root and results were analyzed. RESULTS: Those graded mild had 4.3 months relief and those graded moderate had 2.5 months relief. Those with severe disc prolapse had no relief except for the immediate postprocedural relief. Only 20% patients had relief up to 6 months. CONCLUSION: Effect of SNRB is typically short acting in majority of patients and recurrence is expected. It creates a window period with reduced pain but of varied intervals depending on the pathology. It did not alter the prognosis in those with severe disease where surgery is well indicated. Level of Evidence - Level 4.

Myositis ossificans traumatica causing ankylosis of the elbow.

Myositis ossificans traumatica is an unusual complication following a muscle contusion injury. A significantly large myositic mass causing ankylosis of the elbow is even rarer. We report a 13-year-old boy who presented with a 14-month history of a fixed elbow with no movement and a palpable bony mass in the anterior aspect of the elbow. He had sustained significant trauma to the affected limb 1 month prior to onset of symptoms, which was managed by native massage and bandaging for 4 weeks. The clinicoradiological diagnosis was suggestive of myositis ossificans, and the myositic mass was completely excised. Histopathology revealed lamellar bone. The 2-year follow-up showed full function of the affected limb and no signs of recurrence. We report this case of clinical interest due to the unusually large myositic mass.

Prospective study of treatment outcome of implant retained mandibular overdenture: Two years follow-up.

AIMS: The aim of this study is to evaluate the treatment outcome of immediately loaded Implants in the interforaminal region of anterior mandible. MATERIALS AND METHODS: A total of 15 completely edentulous patients aged between 50 and 70 years were selected satisfying certain inclusion and exclusion criteria. Two implants were placed in 33 and 43 region (B and D location) and the implants were loaded immediately by mandibular overdenture retained with O-ring attachments. The implants were evaluated for various clinical parameters at 6 months, 1 year, 1.5 years, and 2 years intervals after initial placement. RESULTS: There was increased marginal bone loss around implants during the 1(st) year after that the bone loss was insignificant. Clinical stability of immediately loaded implants was lower initially for 6 months, but improved by the end of 1(st) year. Survival rate for immediately loaded implants was 96.6% at the end of the period of study. CONCLUSION: Immediate loading of interforaminal mandibular implants demonstrated a highly acceptable clinical success at the end of 2 years. However, initially the marginal bone level and clinical stability were significantly lower which showed improvement with time.

Comparative evaluation of pre-emptive analgesic efficacy of intramuscular ketorolac versus tramadol following third molar surgery.

Pre-emptive analgesia aims at preventing the central nervous system from reaching a hyper-excitable state known as central sensitization, in which it responds excessively to afferent inputs. The clinical implication would be more effective pain management, thereby reducing post-operative pain and analgesic requirements. This study aimed at investigating the existence of pre-emptive analgesia and to compare the pre-emptive analgesic efficacy of im ketorolac [NSAID] versus tramadol [SYNTHETIC OPIOD] for post-operative pain management following third molar surgery. Fifty patients under the age group of 16-25 years with asymptomatic, symmetrically impacted mandibular third molars were equally divided into 2 groups and underwent third molar surgery under local anesthesia. Ketorolac 30 mg and tramadol 50 mg were used in the study group, while sodium chloride 0.9 % was used in the control group. Study parameters included pain intensity scores for 12 post-operative hours, time to 1st rescue analgesia, total number of analgesics consumed during the 5 post-operative days and patients' self assessment of efficacy of the surgery with regardsto no pain. Statistically, the data are presented as the mean values with their standard deviations and a 95 % confidence interval [p is significant, if p < 0.05] for the mean are applicable. Incidences of adverse events like pain on injection of the study drug, local reactions, nausea and vomiting were noted. Patients in the study group significantly performed better than the control group in terms of all the parameters; while among the study group, ketorolac fared better than tramadol. All the drug related complications were mild and did not require any intervention. Pre-operative ketorolac or tramadol in comparison to placebo resulted in a significantly better post-operative pain management. However as against tramadol, ketorolac is a better choice as a pre-emptive analgesic agent for the post-operative pain management following third molar surgery.
