Critical Realism in Symptom Science - A Scoping Review.

There has been an increasing interest in research positioned within critical realism (CR). This analysis aimed to determine how CR has been applied in symptom science through a scoping review of the literature. Fifty-two articles were identified through searches in seven databases and search engines, and grey literature. Quantitative and qualitative analyses were performed using Excel and ATLAS.ti 8.0. Review findings indicate that CR has been used to examine two key aspects of symptoms - symptom experiences and symptom interventions. The details of how CR was operationalized are presented. This first scoping review highlights how a critical realist lens would help examine individual and contextual factors that influence symptom experiences, response to interventions, and outcomes.

Role of Genetic Testing in the Management of Indeterminate Thyroid Nodules in the Indian Setting.

The increased detection of thyroid nodules in the human population has led to an increase in the number of thyroid surgeries without an improvement in survival outcomes. Though the choice for surgery is straightforward in malignant thyroid nodules, the decision is far more complex in those nodules that get categorized into indeterminate thyroid nodules (ITN) by fine needle aspiration. Therefore, there is a pressing need to develop a tool that will aid in decision-making among the ITN. In this context, the development of various molecular testing (MT) panels has helped to confirm or rule out malignancy, reducing unnecessary surgeries and potentially guiding the extent of surgery as well. Currently, such tests are widely used among the Western population but these MT panels are not used by the South Asian population because of non-availability of validated panels and the high cost involved. There is a need to develop a suitable panel which is population-specific and validate the same. In this review, we would focus on current trends in the management of ITN among the South Asian population and how to develop a novel MT panel which is cost-effective, with high diagnostic accuracy obviating the need for expensive panels that already exist.

Clinical, Radiological and Histological Features and Their Association with Extranodal Extension in Buccoalveolar Complex Squamous Cell Carcinoma.

Jeyashanth RijuObjectives The study was aimed to (1) evaluate the effectiveness of clinical examination, intraoperative finding, and contrast-enhanced computed tomography (CECT) to detect extranodal extension (ENE) in buccoalveolar complex squamous cell carcinoma (BAOSCC), (2) to know various factors influencing ENE, and (3) to evaluate survival outcome in patients with ENE. Materials and Methods This was a retrospective cohort study, which included 137 patients with BAOSCC who underwent curative treatment between May 2019 and April 2021. Collaborative findings suggestive of ENE were noted during preoperative clinical examination, CECT, and intraoperatively, and their efficacy was compared with postoperative histopathology. Also, the various factors associated with ENE were evaluated and compared. Statistical Analysis Univariate and multivariate analysis of parameters was done using multiple logistic regression analysis and significant correlation was determined using chi-square test between ENE positive and negative categories. Analysis of prognosis and survival was done by Kaplan-Meier curve plotting using regression analysis and its significance was compared. Results The overall prevalence of ENE was 18.98% and that of lymph node involvement was 40.88%. CECT (73.1%) was found to be more sensitive in detecting ENE compared to intraoperative examination (46.2%) and clinical examination (34.6%).In comparison with clinical examination (91.9%) or CECT (78.38%), intraoperative examination (93.7%) showed the highest specificity in detecting ENE. Clinical nodal size ≥ 3 cm ( p ≤ 0.001), fixity ( p ≤ 0.001), and clinical number of nodes ( p ≤ 0.001) had significant association with ENE. The presence of thick nodal walls on CECT increased the probability of predicting ENE 15 times ( p = 0.180, confidence interval: 0.3-765.4). After a mean follow-up of 18 months, subjects without nodal positivity had a survival advantage over patients with positive lymph nodes (86.4% vs. 53.3%) and those with ENE (86.4% vs. 23.2%), respectively. Conclusion The results demonstrated that clinical examination can be used as an adjuvant to radiological imaging for prediction of ENE preoperatively. Clinical finding suggesting size of node ≥ 3 cm and ≥ 2 nodes are strong predictor of ENE, in addition to other known predictors. Patients with ENE had an unfavorable prognosis when compared with subjects with metastatic nodes without ENE. Presence of ENE remains one of the strongest factors predicting recurrence and thus poor prognosis.

Definitive Surgery after Neoadjuvant Chemotherapy for Locally Advanced Oral Cavity Cancers: Experience from a Tertiary Care Center.

Mansi AgrawalVidya KonduruBackground Oral cavity cancers require definitive surgical resection as the primary treatment, but with advanced T stage, complete resection with pathologically negative margins might be difficult to achieve. Induction chemotherapy helps achieve the balance between resection and morbidity in locally advanced technically unresectable tumors. The aim of this study was to analyze the impact of surgery in locally advanced, technically unresectable oral cavity cancers after neoadjuvant chemotherapy (NACT). Materials and Methods A retrospective analysis of patients with borderline resectable, locally advanced oral cavity cancers who were given NACT between February 2017 and December 2021 was conducted. Data regarding clinical and pathological characteristics, NACT, surgery, adjuvant therapy, and recurrences was analyzed. Results Of the 69 patients in the study, 69.6% had tongue cancer, rest were gingivobuccal complex cancers. All tumors were resected based on the post-NACT tumor volume and clear margins were achieved in 42% of cases. About 85.4% of the tongue cancers required a lesser resection than anticipated, thereby following the concept of organ and functional preservation post-NACT as proposed by Licitra et al. About 30.4% had ypT0 and 17.4% had ypN0. Recurrence and survival rates noted in our study were comparable to those reported in literature. Lymph node density of more than or equal to 0.07 was found in all recurrent cases. Conclusions Induction chemotherapy offers a chance of achieving adequate surgical resection while reducing morbidity and improving functional outcomes for patients with technically unresectable oral cavity cancers. Nodal disease may not respond to chemotherapy as well as the primary tumor. There is a need for comprehensive evaluation of prognostic factors, which could help identify the patients who will most benefit with NACT.

A Site-Based Analysis of Relationship Between Clinicopathological Factors and Their Influence on Locoregional Recurrence in Oral Squamous Cell Carcinoma.

In India, oral cancers are the major cause of cancer-related death. Tongue and buccal mucosa being the major subsites in oral cancer have varying clinicopathological presentations. This study is intended to know the difference in clinicopathological behavior of these two subsites. This retrospective study included 474 patients of which 232 patients had tongue cancer and 242 patients had buccal alveolar complex (BAC) cancer. Comparison between the pathological characters including pattern of nodal involvement was analyzed. Disease-free survival (DFS) and factors influencing the DFS were analyzed and compared using Cox regression analysis. Mean age of the study population was 52.7 years. Tongue oral squamous cell carcinoma (OSCC) differed significantly from BAC OSCC in terms of age of presentation, tumor staging, and perineural invasion. Among neck nodal involvement, tongue OSCC commonly involved level IIa (p < 0.001) whereas BAC involved level Ib (p < 0.001). At a median follow-up of 27 months, 141 patients had disease recurrence, tongue OSCC commonly recurred in neck (p = 0.008), and BAC OSCC relapsed at primary site (p = 0.001). Patients older than 45 years with BAC cancer had lesser risk of recurrence (HR, 0.30; 95% CI, 0.2-0.5; p < 0.0001). Pathological tumor stage in tongue cancer (HR, 14.9; 95% CI, 2.6-84.8; p = 0.002) and grade of tumor differentiation in BAC OSCC (HR, 9.2; 95% CI, 1.9-43.3; p < 0.005) were the most significant factors that influenced tumor recurrence. There was a significant difference in factors influencing disease recurrence among tongue and BAC OSCC. Also, pattern of nodal metastasis and pattern of recurrence were different. Hence, further research on OSCC may be done site specific. Supplementary Information: The online version contains supplementary material available at 10.1007/s13193-023-01750-8.

Role of Infrared Thermography in Planning and Monitoring of Head and Neck Microvascular Flap Reconstruction.

Background: Reconstruction using microvascular free flaps has become the standard of care in head and neck cancer surgery, and their success lies in appropriate planning, adequate revascularization, and early detection of flap compromise so that prompt salvage is possible. This study evaluates the role of infrared thermography in the planning, execution, and postoperative monitoring of microvascular flaps in head and neck reconstructions. Methods: This is a single institutional, prospective observational study conducted at a tertiary care hospital in South India for 13 months. Twenty patients were included, and their thermographic images were captured in the preoperative, intraoperative, and postoperative settings using the infrared camera FLIR T400. These images were analyzed along with the Doppler, and clinical monitoring findings in all the settings and the temperature difference were calculated postoperatively. Results: Hotspot perforator marking was made using infrared camera, and perforator marking was made using hand-held Doppler preoperatively, which correlated in 93% of cases. Intraoperatively, flap rewarming was successfully demonstrated in 19 of 20 cases. Postoperatively, flap compromise was observed on infrared thermography during the first 24 hours but not on clinical monitoring in three cases. The temperature difference values recorded were 5.4°C, 2.4°C, and 4.9°C. The mean of temperature difference of the healthy flaps was 1.0°C (range 0.1°C-1.8°C). Conclusion: Infrared thermography provides simple and reliable imaging, which can be used in perforator marking and flap designing preoperatively and checking the flap perfusion and vascular anastomosis patency intra- and postoperatively.

Worst Pattern of Invasion as an Independent Predictor of Lymph node Metastasis and Prognosis in oral Cavity Squamous cell carcinoma - A Retrospective Cohort Study.

Although Worst pattern of invasion (WPOI) is one of the histopathological (HP) markers that has been utilized in risk stratification of oral squamous cell carcinoma (OSCC) patients, its potential as an independent predictive factor for lymph node metastasis (LNM) and prognosis is least analyzed. Aim of the study is to analyze the relationship of various HP parameters to WPOI, their propensity for lymph node metastasis and prognostic value. This retrospective study included 140 patients diagnosed with resectable OSCC who underwent definitive surgery. Multiparametric HP risk assessment was done on the postoperative specimen and patients were categorized as low-risk WPOI (Type 1-3), and high-risk group (type 4 and 5). After categorization, 36.1% patients had low-risk WPOI and 63.9% had high-risk WPOI. Significant association was noted between WPOI and patient's age (p = 0.001), nodal stage (p = 0.001), lymphovascular invasion (LVI) (p = 0.006) and neural invasion (p = 0.001). 87% patients with nodal metastasis had high risk WPOI. LVI (p = 0.014) and WPOI (p < 0.001) had significant predictive role in LNM. High-risk WPOI and bone involvement were found to be predictive factors for overall survival, and only high risk WPOI had strong correlation with disease free survival having significant poor prognosis. Analyzing WPOI is essential in reporting HP specimens in OSCC. High-risk WPOI can act as an independent predictor for LNM, early recurrence and poor prognosis. Incorporation of WPOI into TNM staging is recommended to improve clinician's ability to prognosticate and individualize treatment strategies.

Symptom Cluster Experiences of Patients Operated for Oral Cancer: A Mixed Methods Study.

OBJECTIVE: This convergent mixed methods study aimed to obtain a comprehensive understanding of symptom cluster experiences in patients with oral cancer. Survey and phenomenological interviews were conducted in parallel to identify distinct patient subgroups based on symptom cluster experiences along with their predictors and explore experiences of living with symptom clusters, respectively. DATA SOURCES: A convenience sample of 300 patients with oral cancer who had completed surgery provided the quantitative data, and a maximum variation purposive subsample of 20 participants, drawn from the survey sample, provided the qualitative data. Agglomerative hierarchical cluster analysis was used to identify subgroups, multivariate analyses were done to identify predictors, and thematic analysis was used for patient narratives. CONCLUSION: Almost 94% of the survey participants had two or more co-occurring symptoms. The four most severe and prevalent symptoms were dysphagia, problems with teeth or gums, speech difficulty, and dry mouth. A distinct subgroup consisting of 61% of patients reported severe dysphagia and teeth problems, which was associated with age, oral cancer stage and site. Interviews revealed the causes and the context influencing the perception and response to these symptoms. Thus, the quantitative data provided information on severity and patient subgroups based on symptom cluster experiences, while the qualitative data validated these conclusions and additionally provided in-depth details and meaningful insight on perceived causes and contextual influences of their experiences. This comprehensive picture of symptom cluster experiences can aid in the development of patient-centered interventions for people with oral cancer. IMPLICATIONS FOR NURSING PRACTICE: An interdisciplinary approach to targeting concurrent symptoms incorporating psychological and physical interventions is necessary. Older patients treated for Stage IV cancers and for buccal mucosa tumors are at high-risk of having severe dysphagia postoperatively, and these patients should be targeted for dysphagia interventions. The contextual factors play an important role in developing patient-centered interventions.

On a pathway to resigned acceptance: Patients' experiences of living with symptom clusters in oral cancer.

PURPOSE: Patients treated for oral cancer experience multiple concurrent symptoms. A larger mixed-methods study was conducted among patients who were treated with surgery alone or in combination with other modalities. The aim of the qualitative strand was to explore the experiences of living with symptom clusters. METHODS: A phenomenological design was used to explore the lived experiences. Participants were recruited for the larger study from two outpatient units of a tertiary teaching hospital (N = 300). After completion of a survey, a maximum variation purposive subsample of 20 participants was drawn from the larger sample and were interviewed in-depth about their experiences. Thematic analysis was conducted. FINDINGS: All participants experienced multiple concurrent symptoms, commonly including chewing difficulties + dry mouth + speech difficulties; chewing difficulties + dry mouth + diminished taste; and chewing difficulties + dry mouth + speech difficulties + trismus. Analysis of their experiences of living with these symptom clusters revealed six themes: Acknowledged Disruptions, Inner Dialogue, Shifting Expectations, Floods of Emotions, Exercising Control over Life, and Resigned Acceptance. These themes portrayed that time and living with symptom clusters lead to what we describe as a pathway to resigned acceptance. This pathway is intermingled with disruptions, self-reflections on 'why me' and karma, negative emotions, and failed expectations regarding symptom recovery. Attempts to exercise control over their lives were also revealed through coping strategies, watchful living, future planning, and being health advocates. On realizing with time that further symptom alleviation is unlikely, and considering symptom-cluster experiences as being written in their fate, they move towards a state of resigned acceptance. However, unlike passive acceptance, their belief in fate was accompanied with resilience, evidenced by their ongoing efforts to explore pragmatic ways to live with symptom clusters. CONCLUSIONS: Findings provide key insights into patient perspectives which most often remain unexpressed in clinical settings. Further research is required to explore watchful living, fate as a coping strategy, and intertwining of faith, fate, and karma.

Difference in clinical presentation and their significance in oral squamous cell carcinoma: A retrospective analysis.

BACKGROUND: Oral squamous cell carcinoma (OSCC) remains the most common cancer among Indian men. OSCC involving the tongue and bucco alveolar complex (BAC) behaves differently. Nevertheless, the differences in clinical features and symptoms between the two subsites and their relation to pathology remain largely unexplored. STUDY DESIGN: The study compared various clinical parameters and pathological factors between tongue cancer patients and patients with BAC cancer. RESULTS: Among 474 patients, 232 had tongue cancer and 242 had BAC cancer. Except for the ulcer, 30% of patients with OSCC were asymptomatic at presentation. Compared to tongue cancers, lesions confined to BAC present at an advanced stage (P = 0.006). Multivariate analysis showed that dysphagia in tongue cancer (P = 0.020) and external swelling or lesion in BAC cancers (P = 0.002) were significant predictors of an advanced stage of the disease. On histopathology, perineural invasion (PNI) was significantly associated with tongue (P = 0.008) compared to BAC cancers (P = 0.015). Cancers of the tongue with pain and referred otalgia had a significantly higher depth of invasion (DOI), compared to those without pain (DOI - no pain 6.9 mm, pain 9.9 mm, and referred otalgia 11.4 mm). CONCLUSIONS: Patients with OSCC present late and in an advanced stage of the disease. Among tongue cancers, clinical history of pain was significantly associated with DOI and PNI, the significance of which needs to be prospectively analyzed. Clinical history in OSCC can be used as predicting factor for an advanced pathological stage of the disease. It also had an influence on various pathological characters, which is subsite specific.

Contralateral Nodal Metastasis from Tongue Malignancy.

Oral cavity is the most common site of cancer in India, tongue forms the most common single subsite. Neck node involvement plays an important prognostic role in disease-free survival and overall survival. Most of the nodal metastasis are occult and only an elective neck dissection can disclose the nodal metastasis, which is accepted only when the risk of metastasis exceeds 15-20%. Contralateral nodal metastasis(CLNM) are rarely analyzed due to sparse event.Retrospective analysis of data of patients who underwent surgery for carcinoma tougue with a curative intend between April 2017 and March 2019 were collected. Factors influencing CLNM in carcinoma tongue were studied.The study included 149 patients, with 102 men and 47 women. The mean age of study subjects was 51.5 ± 11.8 years. Thirteen (8.7%) patients had CLNM. With respect to tumor, advanced stage(p < 0.001), floor of mouth involvement(p = 0.001) and lesion crossing midline(p < 0.001) had an increased risk of CLNM. Extranodal extension(ENE)(p < 0.001) and lymphnode ratio(p = 0.002) in ipsilateral node ratio influenced CLNM. Multivariant analysis showed that in addition to lesion crossing midline(p = 0.03), ENE played significant role in CLNM (p < 0.001), with a risk of 12.8 times compared to no ENE. Suspicion of CLNM either clinically/radiologically was a good predictor of metastasis(p < 0.001).CLNM in tongue cancer was significantly influenced by lesion crossing midline and ENE. Contralateral neck dissection should be performed in any case with clinical/radiological suspicion of nodal involvement and above mentioned risk factors.

Solitary fibrous tumor of the masticator space - Report of a rare case.

The solitary fibrous tumor (SFT) is a potentially malignant spindle cell neoplasm of the mesenchymal origin that was originally described as a thoracic lesion originating from the pleural tissue. Recently, numerous extrapleural sites of origin have been described, also affecting the head and neck region. SFTs are benign in most cases, but 10%-15% of extrapleural SFTs show malignant behavior in the form of recurrent or metastatic disease. We present the case of a 25-year-old female who presented with an asymptomatic left-sided facial swelling of over three years. She had a diffuse swelling in the left preauricular region, extending to the temporal region deep to the zygomatic arch. On magnetic resonance imaging, the vascular lobulated mass occupied the masticator space, infratemporal fossa, and parapharyngeal space, eroding the mandible. An ultrasound-guided fine-needle aspiration cytology was suggestive of SFT, positive for signal transducer and activator of transcription 6 and negative for TLE1. After preoperative embolization, the tumor was excised through a midline lip split approach with posterior segmental mandibulectomy and reconstruction with a titanium plate. Histopathological report was consistent with SFT. Due to high-risk features, she was advised adjuvant radiation therapy. SFTs of the head and neck are exceedingly rare and those with aggressive behavior even more so. To our knowledge, this is the only case of SFT arising in the masticator space. Diagnosis is often difficult and not definitive without immunohistochemistry. In most cases, complete surgical excision is the only treatment necessary. Regardless, all patients require close clinical follow-up for several years.

An alternative method for reconstructing anterior segmental mandibulectomy defects with a plate and pectoral major muscle flap.

Background: Reconstruction of anterior segmental mandibulectomy still remains a challenge. Osteocutaneous free flap remains the ideal choice of reconstruction because it restores cosmesis and function. The use of other locoregional flaps compromises cosmesis and function. Here, we have introduced a unique technique of reconstruction with lingual cortex mandibular plate as an alternate choice for free flap. Method: Six patients aged 12-62 years underwent oncological resection for oral cancer which involved the anterior segment of the mandible. Following resection, they underwent lingual cortex mandibular plating with pectoralis major myocutaneous flap reconstruction. Adjuvant radiotherapy was delivered to all patients. Results: The mean bony defect was 9.2 cm. There were no significant perioperative events related to the surgery. None required tracheostomy and all were safely extubated with no post-surgical complications. The cosmetic and functional outcomes were acceptable. Following the completion of radiotherapy with a median follow-up of 11 months, Plate exposure occurred in one patient. Conclusion: The technique is cheap, quick and simple, and can be effectively applied in resource-constrained and demanding situations. It is possible to consider this as an alternative treatment strategy for osteocutaneous free flap in anterior segmental defects.

Trigeminocardiac Reflex as a Complication of Excision of Schwannoma of the Trigeminal Nerve - A Rare Clinical Case Report.

Rationale: Trigeminal schwannoma (TS) is a very rare tumour in the head-and-neck region and the occurrence of intraoperative trigeminocardiac reflex (TCR), during surgery, should not be underestimated. The physiological function of this rare brainstem reflex is yet to be fully established. Patient Concerns: TCR occurs in a variety of surgeries, such as neurosurgical, maxillofacial, dental and skull base surgeries with bradycardia as the presenting sign. Diagnosis: This is a clinical profile of two patients who presented with schwannoma of the trigeminal nerve. Outcomes: Intraoperatively, during dissection of tumour, both patients had bradycardia with hypotension. Treatment: The first patient had a spontaneous recovery but the other required intervention with vasopressors. Take-Away Lessons: One must be aware of the rare occurrence of TCR mainly while operating on a rare occurring TS. Ceaseless intraoperative monitoring and being prepared with adequate measures while manipulating close to the nerve will prevent serious complications.

Abnormal Course of Internal Carotid Artery Encountered During Neck Dissection.

Internal carotid artery (ICA) is one of the most important structures to be preserved during neck dissection. Many anomalous courses of ICA have been explained and must be kept in mind while proceeding with surgery. The variation mentioned in this article has not been described yet. This is very important for head and neck surgeons, especially while performing neck dissection or external carotid artery ligation. A 51-year-old male with no known comorbidities underwent surgery for carcinoma right buccal mucosa. As noted in preoperative imaging, intraoperatively he had a abnormal course of ICA especially with abnormal relation to the internal jugular vein (IJV). It is imperative to study the anatomy of ICA preoperatively to prevent intraoperative surprises. A careful dissection of the level II cervical region keeping in mind regarding an aberrant course of ICA especially with relation to IJV can prevent catastrophic consequences.

Symptom Clusters in Head and Neck Cancer: A Systematic Review and Conceptual Model.

OBJECTIVE: The two approaches to symptom-cluster research include grouping symptoms and grouping patients. The objective of this systematic review was to examine the conceptual approaches and methodologies used in symptom-cluster research in patients with head and neck cancer. DATA SOURCES: Articles were retrieved from electronic databases (CINAHL, MEDLINE via Ovid, APA PsycINFO, Scopus, Embase, and Cochrane Central Register of Controlled Trials-CENTRAL), five grey literature portals, and Google Scholar. Seventeen studies met the eligibility criteria. Eight studies grouped symptoms to identify symptom clusters, of which two used qualitative methods. The number of symptom clusters ranged from two to five, and the number of symptoms in a cluster ranged from 2 to 11. Nine studies grouped patients based on their experiences with multiple symptoms. Cluster analysis and factor analysis were most commonly used. Despite variable names and composition of symptom clusters, synthesis revealed three prominent symptom clusters: general, head and neck cancer-specific, and gastrointestinal. Being female and quality of life were significantly associated with high symptom group or cluster severity. Biological mechanisms were sparsely examined. CONCLUSION: Symptom cluster research in head and neck cancer is emerging. Consensus on nomenclature of a symptom cluster will facilitate deduction of core clinically relevant symptom clusters in head and neck cancer. Further research is required on understanding patients' subjective experiences, identifying predictors and outcomes, and underlying mechanisms for symptom clusters. IMPLICATIONS FOR NURSING PRACTICE: Identification of clinically relevant symptom clusters would enable targeted symptom assessment and management strategies, thus improving treatment efficiencies and patient outcomes.

Analysis of Early Impact of COVID-19 on Presentation and Management of Oral Cancers - an Experience from a Tertiary Care Hospital in South India.

Oral cancers are the leading cause of cancer-related death in Indian men. Currently steps to contain the transmission and treatment of COVID-19 pandemic have crippled the entire health care system. With hospitals running short of resources, the oncological practice became standstill, especially during the initial phase. This is a retrospective study among patients who presented to our tertiary care hospital in early 3 months of COVID-19 era(ECE) with respect to pre-COVID-19 era(PCE). The study includes patients discussed in multidisciplinary tumor board(MDT)(421 in ECE Vs 31 in PCE) and those who underwent surgery(192 in ECE Vs 26 in PCE). The presentation and outcomes of oral carcinoma were compared between the two eras. There was a significant drop in the number of patients who presented during ECE. Though mean age and gender remained comparable between groups, there was a statistical difference in relation to demographic profile of patient (p value < 0.001). Among operated during ECE, 80% had a significantly advanced tumor stage (p value < 0.034) and advanced composite stage (p value < 0.049). Among patients discussed in MDT during ECE, 38.7% were deemed inoperable which is double the number when compared with PCE (p value < 0.009). Results of our study showed a higher incidence of advanced stage disease during ECE, with many patient turning inoperable. Thus, the survival of newly diagnosed oral carcinoma patients will be worser. In the management of oral cancer both early stage and advanced stage should have the same priority. Immediate resumption of safe oncology services is mandatory to curtail the current issues.

The folded, bipaddled pectoralis major myocutaneous flap for complex oral cavity defects: Undiminished relevance in the era of free flaps.

Oral cancer often presents at an advanced stage, requiring extensive resection and complex reconstruction, such as free tissue transfers, which may not be available in a remote or resource-constrained facility. The common alternative in these cases is the use of the workhorse flap, the pectoralis major myocutaneous (PMMC) flap for lining and a second regional flap for cover. The results are variable, increase operative time and cost, and may cause additional donor site morbidity. We present a series of patients who underwent reconstruction for complex oral cavity and neck defects with a single PMMC flap with a unique design, folded or bipaddled to serve as both lining and cover. Pre- and post-operative data pertaining to patients with oral cancer who were selected to undergo bipaddled PMMC flap reconstruction in our unit between January 2017 and July 2019 were collected and analysed. Of the 41 patients, 28 were males and 13 were females. The surgical resection involved full-thickness excision of primary tumour and involved skin (face or neck) for oral cancers. The size of skin paddle harvested ranged from 8 to 15 cm horizontally to 6 to 22 cm vertically. Usually, the distal part of the skin paddle formed the mucosal lining and the proximal formed the skin cover. Complication rates in the immediate postoperative period and on initial follow-up visits were comparable to a conventional PMMC flap. Reconstruction of complex head and neck defects requiring mucosal lining and skin cover can be achieved with a single stage, bipaddled PMMC flap, a reliable and easily learnt alternative to technically demanding free tissue transfers. The complication rate observed in our series is remarkably low, even in females. With a proper design of the flap and appropriate orientation of the skin paddle, excellent results can be achieved with a bipaddled PMMC flap.

Bilateral total conservative parotidectomy: a tale behind an aesthetic surgery.

Any facial swelling is associated with stress for the patient due to cosmesis. Especially when one has bilateral symmetrical enlarged parotids, having exhausted all available conservative management, surgery becomes the last resort; which in such cases pose specific challenges. A 29-year-old man presented with problems of bilateral symmetrical enlarged parotid lesion for 5 years, which did not have an adequate response to medical line of management. He underwent proposed surgery and was diagnosed to have chronic sclerosing parotitis (CSS). The challenges faced during surgery of this non-neoplastic inflammatory lesion, with significant fibrosis, is being described. He recovered completely without any complications related to surgery. CSS rarely affects bilateral parotid glands. Surgery, results of which are outstanding, must be considered in cases where these lesions do not respond to medical line of management. Bilateral total conservative parotidectomy with sternocleidomastoid flap reconstruction provides excellent aesthesis and improves quality of life.

Elusive treatment for human rhinosporidiosis.

OBJECTIVES: The aim of this study was to clarify the contentious taxonomic classification of Rhinosporidium seeberi, the cause of human rhinosporidiosis, which may have treatment implications. METHODS: PCR was used to amplify the internal transcribed spacer (ITS)-2 region from the genomic DNA of the aetiological agent obtained from a sample of human rhinosporidiosis lesions. The amplicon was sequenced and the organism identified using the Basic Local Alignment Search Tools (BLAST). RESULTS: Phylogenetic analysis revealed that the aetiological agent clustered along with the R. seeberi isolated from humans and also with Amphibiocystidium ranae from frogs. This organism is a member of the order Dermocystida in the class Mesomycetozoea. A patient with disseminated rhinosporidiosis did not respond to conventional therapy with dapsone and surgical excision, and treatment with amphotericin B also proved futile. CONCLUSION: An effective treatment for R. seeberi-a eukaryote belonging to the class Mesomycetozoea-is still elusive.
