Osteolipoma of head and neck - a review

Abstract Objective: Due to the rarity of osteolipoma, current knowledge and understanding of its' clinical presentation, management, radiological features, histological characteristics, and prognosis are lacking and can present a clinical conundrum to clinicians and histopathologist alike, given wide range of differential diagnoses. This paper aims to compile, analyse and present details to augment the available literature on osteolipoma in the head and neck. Methods: A comprehensive literature search on PUBMED/MEDLINE, EMBASE, CINAHL and Science Citation Index, Google scholar and Cochrane database for osteolipoma in head and neck was performed up to the 1st May 2021. Reference lists from the relevant articles were then inspected and cross-referenced and any other pertinent publications were added to the review. Results: A total of 38 cases were identified from the literature. The commonest sites of involvement within the head and neck region were the oral cavity in 21 (56.8%) patients, followed by the neck in 7 (19.0%) patients. 29 (78.4%) patients presented with soft tissue swelling or mass making it the most common presenting feature. All patients had the tumour excised surgically; of which 18 (48.6%) were excised via transoral approach and 6 (16.2%) via open transcervical approach including 1 lateral pharyngotomy. 12 papers documented long-term follow-ups (median 12 months) with no recurrence. Only 1 regrowth was reported after 5-years. Conclusions: Osteolipoma is a rare soft tissue neoplasm which has a wide range differential diagnosis including malignant processes. Recognising this benign tumour through an awareness of presenting sign and symptoms, radiological features and histopathology findings is important for patient reassurance as well as avoiding unnecessary radical treatment.

Airwayplasty: long-term outcome of nasal wall lateralisation.

BACKGROUND: There are a variety of surgical techniques which can be used to treat structural nasal obstruction. Airwayplasty is a procedure, combining septoplasty, turbinate surgery, and nasal wall lateralization. The article reports the long-term result of this novel approach. METHODOLOGY: Patients who have evidence of structural nasal obstruction were offered the option to have airwayplasty under the senior surgeon. Patients were asked to quantify the severity and the impact of their nasal obstruction using the Visual Analogue Scale (VAS) and the validated Sino-Nasal Outcome Test (SNOT-22) pre-operatively and post-operatively. RESULTS: The mean total SNOT-22 score and VAS score showed a reduction of more than 50% with significant p value at 6 and 12 months post-operatively. CONCLUSIONS: This novel approach to nasal obstruction can provide good long-term functional results for patients suffering from nasal obstruction.

Laryngeal schwannoma: a systematic review.

A large proportion of schwannomas are found in the head and neck region. Schwannoma located within the larynx however is uncommon. The characteristic features, clinical presentations, treatment and the outcomes of patients with laryngeal schwannoma are therefore not clearly understood. The aim of this comprehensive review is to compile, analyze and present the details to develop a consensus and augment the available literature on laryngeal schwannoma. A comprehensive literature search on laryngeal schwannoma was performed on PUBMED/MEDLINE, EMBASE, CINAHL and Science Citation Index using MeSH words. A total of 55 patients were reviewed in this study. 40.7 % of the tumours arose from the aryepiglottic fold or arytenoids. Other areas where tumours were found included the false cord, true vocal cord, epiglottis, subglottis, piriform sinus and the post cricoid area. 64.9 % patients presented with dysphonia. Others typically present with multiple symptoms related to the mass effect and location of the tumour. All patients were managed surgically with different techniques and approaches. Majority of patients were alive with no residual disease. There were five recurrences and no mortality to date. Schwannoma within the larynx can present with a variety of symptoms. Surgical excision remained as the treatment of choice with good overall prognosis.

Kaposiform haemangioendothelioma of the head and neck.

BACKGROUND: Kaposiform haemangioendothelioma (KHE) is a tumor of intermediate malignant potential derived from vascular endothelial cells. Due to rarity of head neck KHE (HN-KHE) this comprehensive review aims to compile, analyze and present details to develop a consensus and augment available literature on HN-KHE. MATERIALS AND METHODS: A comprehensive literature search was performed on PUBMED/MEDLINE, EMBASE, CINAHL and Science Citation Index for HN-KHE using MeSH words. Statistical analysis was performed using a variety of tests. RESULTS: Common sites of involvement were neck 41.5%, face and scalp 32.0% and tympanomastoid region in 13.2% patients. Kasabach-Merritt phenomenon was seen in 58.5% patients. Surgical excision was performed in 37.7% patients while 39.6% patients underwent medical management/chemotherapy (CT). Significantly better disease free survival (DFS) was seen in patients undergoing surgical excision vs. CT (p=0.001), without recurrence vs. with recurrence (p=0.001) and those presenting within 0-1year of life vs. 1-5 years (p=0.021). CONCLUSION: Recurrence and metastasis were seen in 35.8% and 20.0% patients respectively. Complete surgical excision with clear margins remains the treatment of choice.

Ruxolitinib Associated Tuberculosis Presenting as a Neck Lump.

Tuberculosis is an opportunistic infection with protean clinical manifestations. We describe a case of Ruxolitinib induced miliary tuberculosis presenting as a neck lump. A 78-year-old female presented with a two-month history of right-sided neck lump associated with fever, night sweats, and significant weight loss. She had a past medical history that included myelofibrosis, being treated with Ruxolitinib. Examination demonstrated 4 × 4 cm right-sided cervical lymphadenopathy. A chest radiograph showed extensive shadowing in both lungs. CT scan demonstrated perilymphatic nodes in addition to the cervical mass. An ultrasound-guided biopsy of a cervical lymph node demonstrated confirmed Mycobacterium tuberculosis infection. It was hypothesized that use of Ruxolitinib through its selective inhibition of Janus-activated kinases 1 and 2 resulted in immunosuppression and miliary tuberculosis in this patient. The medication was stopped and a 12-month regime of antituberculosis therapy commenced. She remained well at one-year follow-up with resolution of lung involvement. Clinicians should consider tuberculosis as a differential diagnosis for patients presenting with a neck lump, particularly in those taking immunosuppressant medication such as Ruxolitinib. A multidisciplinary approach is needed to promptly treat the tuberculosis and consider discontinuation of Ruxolitinib.

Kaposiform hemangioendothelioma of paranasal sinus.

Kapossiform hemangioendothelioma (KHE) of the paranasal sins (PNS) is a rare cause of recurrent epistaxis. To date, only two cases of PNS KHE have been reported in the literature, both occurring in the pediatric population. The case presented here appears to be the first case of PNS KHE occurring in an adult. A 46-year-old white female presented with progressively worsening unilateral recurrent epistaxis. Diagnostic histopathology confirmed it to be KHE. After a detailed workup, the tumor was completely excised en bloc (medial maxillectomy; anterior and posterior ethmoidectomy) via a lateral-rhinotomy approach. Complete excision of the tumor with clear margins offers the best results.

Simultaneous dislocation of proximal and distal radio-ulnar joints: a case report.

Simultaneous dislocation of the radial head and distal radio-ulnar joint is rare. We report a 71-year-old man with volar dislocation of the radial head and dorsal dislocation of the distal radio-ulnar joint, and discuss the injury mechanism and its management with closed reduction.

The use of tramadol "on-demand" for premature ejaculation: a systematic review.

OBJECTIVE: To determine the efficacy and safety of tramadol in the treatment of premature ejaculation (PE) by systematically reviewing the results of randomized controlled trials. MATERIALS AND METHODS: All studies evaluating the efficacy of tramadol for the treatment of PE published in peer reviewed medical journals between 2006 and March 2012 were identified by searching for the keywords "premature ejaculation" and "tramadol" in the PubMed database. Only randomized controlled trials published in the English language were included. RESULTS: A total of 5 articles, comprising 823 patients, met the inclusion criteria for further analysis. Overall, tramadol on-demand results in a significant improvement in mean intravaginal ejaculatory latency time and symptom scores compared with placebo and in an improvement in partner sexual satisfaction scores. The rate of short-term adverse effects is low. CONCLUSION: Tramadol is an effective treatment for patients with PE and represents a promising alternative to the currently used oral pharmacologic agents. Longer-term safety studies, and those comparing tramadol with the selective serotonin receptor inhibitors, are essential to determine the place of tramadol in the treatment of this distressing condition.
