Prevalence and trends of human papillomavirus in oropharyngeal cancer in a predominantly north Indian population.

Human papillomavirus (HPV) prevalence in oropharyngeal squamous cell cancer (SCC) remains variable and studies have estimated that up to 60% may be positive.

Cochlear implantation in Waardenburg syndrome: The Indian scenario.

Abstract Conclusion: Children with Waardenburg syndrome (WS) exhibiting normal inner ear anatomy, like those included in our cohort, derive significant benefit from cochlear implantation and results are comparable to those reported for the general population of implanted children. Objectives: The patient population of WS accounts for approximately 2% of congenitally deaf children. The purpose of this retrospective case review was to describe the outcomes for those children with WS who have undergone cochlear implantation. Methods: On retrospective chart review, there were four cases with WS who underwent cochlear implantation. These cases were assessed for age at implantation, clinical and radiological features, operative and perioperative course, and performance outcomes. Auditory perception and speech production ability were evaluated using categories of auditory performance (CAP), meaningful auditory integration scales (MAIS), and speech intelligibility rating (SIR) during the follow-up period. Results: In this group of children with WS, with a minimum follow-up of 12 months, the CAP score ranged from 3 to 5, MAIS from 25 to 30, and SIR was 3. These scores are comparable with those of other cochlear implantees.

Proton Pump Inhibitors Versus Solitary Lifestyle Modification in Management of Laryngopharyngeal Reflux and Evaluating Who is at Risk: Scenario in a Developing Country.

Background Laryngopharyngeal reflux disease can present with a varied symptomatology because of the involvement of multiple sub-sites of the upper aero-digestive tract. It is a very common disease to be encountered in routine practice by both medical and ENT personnel. Its association with multiple pathologies including malignancy warrants an early diagnosis and management. The lack of cost effective and non-invasive tests constitutes a major hurdle in its early management. Objectives 1. To define the “at risk” population, prone to developing laryngopharyngeal reflux. 2. To formulate major and minor risk factors for the clinical diagnosis of patients with laryngopharyngeal reflux. 3. To evaluate the efficacy of lifestyle management alone as a treatment option. 4. To formulate a treatment protocol for the management of patients and to prevent recurrence. Study Design We performed a prospective analysis of 234 patients diagnosed with laryngopharyngeal reflux. Patients were randomized into study and control groups based on the treatment protocol, using a computer generated randomization table and were single blinded to the type of therapy received. A complete analysis of the possible risk factors, symptoms, and signs was performed with statistical analysis. Results and Conclusion The data has helped us define the “at risk” population and formulate the criteria to diagnose cases of laryngopharyngeal reflux, clinically. The results emphasize the non-requirement of invasive or costly investigations for all patients and indicate the probable protocol to be followed prior to considering further investigation. The role of long term proton pump inhibitor treatment along with lifestyle modification in the initial phase of treatment, as mentioned in the literature, was re-confirmed by our study. However, in addition to the initial treatment, the study establishes the need for continuing lifestyle modification further for at least six months after the cessation of proton pump inhibitor therapy to prevent early recurrence of symptoms.

Evaluation of epithelial proliferation in paediatric and adult cholesteatomas using the Ki-67 proliferation marker

INTRODUCTION The aggressiveness of cholesteatoma in children compared with adults is well known. However, the factors influencing the poorer prognosis of paediatric cholesteatoma are not well understood. This study compared the proliferative potential of paediatric cholesteatoma with that of adult cholesteatoma, using Ki-67 as a proliferation marker. METHODS A prospective study of 67 patients with aural cholesteatoma was performed. Thirty-eight adult and 29 paediatric cases were evaluated using clinical parameters including bone erosion, complications and extent of disease. A surgical specimen underwent histological evaluation and measurement of the proliferation index using Ki-67 labelling. Normal epithelium from a control group was also examined. RESULTS Cholesteatoma epithelium has a greater rate of proliferation than normal skin. There were however no statistical differences between the paediatric and adult cholesteatoma groups in terms of clinical behaviour or proliferation potential. Paediatric cholesteatoma was similar to adult cholesteatoma in terms of complications, bone erosion and disease spread. CONCLUSION Cholesteatoma is a disorder of epithelial proliferation. Although postulated to be more aggressive in children than adults, this study found no clinicopathological differences between paediatric and adult cases.

Foreign Body Esophagus: When Endoscopic Removal Fails…

Aspiration or ingestion of a foreign body has frequently been reported in the pediatric and in the adult population. Among many foreign bodies to be ingested, artificial denture is one to be impacted in the esophagus, especially among the elderly. Radiolucency of dental prosthesis complicates early diagnosis of an impacted or ingested dental prosthesis. Rigid and flexible esophagoscopes have been used to retrieve the foreign body from the esophagus but the need for open surgery to remove the foreign body as a rescue procedure to endoscopy or the primary procedure has not been well defined. Here we report a case of impacted foreign body esophagus which was managed primarily by surgery and another case where surgery was performed after trials of endoscopic approach had failed.

Autologous embedded foreign body of mobile tongue

Foreign bodies of upper aerodigestive tract are common otorhinolarygological emergencies. The foreign bodies of mobile tongue are however very rare and there are only limited case reports in literature. The case of a young female with an autologous foreign body mobile tongue with unusual presentation is presented.

Bilateral congenital alveolar synechiae—a rare cause of trismus

Congenital alveolar synechiae is a rare anomaly mostly presenting in association with cleft palate. Owing to reduced mouth opening, feeding difficulties, and compromised airway in extreme cases along with presentation in early neonatal period, these patients present unique challenges to the surgeon as well as the anesthetist. Here, we discuss the surgical and anesthetic management of this entity in a 12-month-old female child.

A phase 2 randomized study to compare short course palliative radiotherapy with short course concurrent palliative chemotherapy plus radiotherapy in advanced and unresectable head and neck cancer.

BACKGROUND Treatment of unresectable HNSCC is not well defined and has a poor outcome. This study has been designed to address the unmet needs of such groups of patients with primary end points of (a) proportion of patients eligible for radical treatment in each arm (b) loco-regional disease control at 6months between two arms. MATERIALS AND METHODS Locally advanced and unresectable HNSCC patients (except Nasopharynx and Larynx) unfit for radical treatment were randomized to arm A [short course RT alone (4Gy/#/day for 5days)] or arm B [RT as arm A+concurrent cisplatin at 6mg/m(2)/day IV bolus for 5days]. Those with at least PR were taken for further RT to complete biological equivalent dose of 70Gy, in both the arms. In arm B, concurrent CDDP at a dose of 40mg/m(2)/week was administered. RESULTS 114 patients (57 in each arm) were randomized but 111 were analyzable. 15 (27.27%) patients in arm A and 28 (50%) patients in arm B had ⩾PR (p=0.01) however patients taken for FRT were 14 (25.45%) and 26 (46.42%) in arms A and B respectively (p=0.02). Locoregional control i.e. (CR+PR) at 6months was 16.36% in arm A versus 32.14% in arm B (p=0.15). Median PFS (arm A - 3.2months, arm B - 6.2months; p=0.02) and OS (arm A - 5.9months, arm B - 10.1months; p=0.03) was significantly more in arm B. There was relative improvement in quality of life for most parameters in arm B. CONCLUSION Concurrent low dose CTRT can be an effective treatment modality in advanced and incurable HNSCC. However, a larger phase III trial is required.

Extrapulmonary Small Cell Carcinoma - a Case Series of Oropharyngeal and Esophageal Primary Sites Treated with Chemo-Radiotherapy

BACKGROUND The optimal sequence and extent of multimodality therapy remains to be defined for extrapulmonary small cell carcinoma because of its rarity. The purpose of our study was to assess the response to neoadjuvant chemotherapy followed by chemoradiation/radiation in patients with extrapulmonary small cell carcinoma. MATERIALS AND METHODS Four consecutively diagnosed patients were included in this study. The primary tumor site was oropharynx in three patients and esophagus in one. The patients with the limited disease were treated with chemotherapy followed by concurrent chemoradiation (n=2) or radiotherapy (n=1). The patient with the extensive disease with the primary site in vallecula was treated with chemotherapy and palliative radiotherapy to the metastatic site. RESULTS The median follow-up was 22.5 months (range, 8-24 months). Three patients with the limited disease (base of tongue, n=2; esophagus, n=1) were in complete remission. The patient with the extensive disease died of loco-regional tumor progression at 8 months from the time of diagnosis. CONCLUSIONS The combination of chemotherapy and radiotherapy is the preferred therapeutic approach for patients with extrapulmonary small cell carcinoma. Induction chemotherapy followed by concurrent chemoradiation or radiation provides a good loco-regional control in patients with limited disease.

Anaesthetic management of endoscopic resection of juvenile nasopharyngeal angiofibroma: our experience and a review of the literature

Abstract Background: Juvenile nasopharyngeal angiofibroma (JNA) is a rare, benign, vascular tumour in adolescent males with potential life-threatening complications. Advances in endoscopic surgery, invasive monitoring and hypotensive anaesthesia have made JNAs amenable to endoscopic surgical resection. We present the anaesthetic management of endoscopic resection of 14 JNAs, together with a review. Method: The medical records of patients who underwent endoscopic excision of JNAs within the last seven years were reviewed retrospectively. Information was collected and analysed with regard to demographics, preoperative evaluation, intraoperative management, complications and postoperative course. Fourteen patients were included in the study. If the surgery needed to be converted to open surgery, the patients were excluded from the study. Results: The age of the patients ranged from 10–18 years. Two patients had preoperative embolisation of the feeding vessel. Standard anaesthesia induction technique, together with invasive monitoring, was used. Controlled hypotension (mean arterial pressure of 60 ± 5 mmHg) was achieved with the help of inhalational anaesthetics, vasodilators and beta blockers. Mean duration of surgery was 197.14 ± 77 minutes, and median blood loss was 500 ml (100- 4 300 ml). Seven patients were extubated in the operating room. The other seven patients remained intubated for 24 hours owing to extensive surgery with a risk of postoperative bleeding, and were monitored either in the postoperative care unit (five patients) or the intensive care unit (two patients). There was no significant morbidity or mortality in any of the patients. Conclusion: JNAs remain a challenge for anaesthesiologists because of excessive intraoperative bleeding. Anaesthetists should be aware of recent techniques to reduce tumour vascularity, such as embolisation of the feeding vessel and controlled hypotension. Invasive monitoring, together with multimodal blood conservation strategies, decreases blood loss and provides a clear field of vision for endoscopic surgery.
