Screening for malnutrition in oral cavity cancer patients prior to treatment: A cross-sectional study.

This study was conducted to assess the frequency of pre-operative malnourishment in patients being treated for oral cavity squamous cell carcinoma. A retrospective chart review was carried out at the Aga Khan University Hospital, Karachi, on 62 patients. Patients were screened pre-operatively through a standard nutritional assessment tool at the time of admission to assess for malnutrition. Mean age of presentation was 48.34±13.11 years, mean height was 165 ± 8.62cm, weight 66.09±14.98 kg and BMI of 24.09±4.84. Males were 82.3% and 17.7% were females. At the time of admission, a significant number or patients, 12 (19.4%) were prone to malnourishment, while 3 (4.8%) patients were malnourished: Assessment was done by using a standardised nutritional assessment tool.

Malignancy Rate in Thyroid Nodules with Atypia or Follicular Lesion of Undetermined Significance

Abstract Introduction Atypia of undetermined significance (AUS) or follicular lesion of undetermined significance (FLUS) is one of the six diagnostic categories of the Bethesda System for Reporting Thyroid Cytopathology. The prevalence of malignancy among Bethesda category III cytology is variable, ranging from 5% to 37% in the literature. Objective To determine the rate of malignancy in thyroid nodules reported as Bethesda category III. Methods A total of 495 patients underwent surgical intervention for thyroid nodules from January 2015 to December 2017. The present study included 81 cases reported as Bethesda category III, and their medical records were reviewed. Results Out of 495 fine-needle aspiration cytology samples, 81 (16.4%) samples were labeled as AUS/FLUS. Among these 81 patients, the mean age was 43.0 years (±13.9), with only 11 (14%) patients older than 55 years of age.Most of our patients were female (n=69; 85.2%), and the rest were male. The rate of malignancy based on the final histology was of 33.3% (n=27). The majority were 17 cases (21%) of papillary carcinoma, followed by follicular carcinoma (n=6) (7.4%). Conclusion The risk of malignancy can be higher than it is commonly believed, and guidelines should be based on the data from the institutions themselves for a better assessment of the outcomes.

Readmissions After Day Care Surgery In Ent: A Tertiary Care Experience.

BACKGROUND: Re-admission following day care surgery in ENT (Ear, Nose & Throat) results in significant morbidity to patient & massive load to hospital & also raises the question on the safety of day care surgery. Only a small number of published studies emphases on return to hospital within 30 days following day care surgery in otorhinolaryngology especially from our region. This study was carried out to determine the frequency of re-admission after day care surgery in ENT. METHODS: We prospectively studied consecutive patients who underwent ENT procedures [i.e., septoplasty, tympanoplasty type I & functional endoscopic sinus surgery (FESS) for deviated nasal septum (DNS), chronic suppurative otitis media tubotympanic (CSOM TT) variety & ethmoidal nasal polyposis (ENP) respectively] as day care surgery case under general anaesthesia at the Section of Otorhinolaryngology and Head & Neck Surgery, Aga Khan University Hospital & Liaquat National Hospital, Karachi from January 2015 to December 2016. All patients aged 20- 60 years of both genders were included in the study. SPSS software version 20 was used for data compilation and analysis. p-value less than or equal to 0.05 was taken as significant. RESULTS: In the phase of 24 months, total 317 cases met the inclusion criteria & were included in the study. There were 205 males & 112 females in the study population. One hundred & twenty-two patients having DNS, 128 having CSOM TT & 67 suffering from ENP & underwent septoplasty, tympanoplasty type I & FESS respectively. Complications were observed in a total of 7 (2.2%) patients in our study group & required re-admission within 1 month of surgery. Stratification was done between re-admission & all effect modifiers, with all showing insignificant results. CONCLUSIONS: Our results demonstrate that ENT surgeries (septoplasty, tympanoplasty type I & FESS) are safe procedures which can be performed as a day care case with acceptably low readmission rates.

Determination of Factors Associated with Critical Weight Loss in Oral Cavity Carcinoma Patients: A Retrospective Cohort Study

Abstract Introduction Critical weight loss is defined as an unintentional weight loss of ≥ 5% at 1 month or ≥ 10% at 6 months from the start of treatment. Critical weight loss leads to deterioration of the immune function and reduced tolerance to treatment (surgery ± radiochemotherapy) as well as increased complication rates. Objective Critical weight loss, defined as a weight loss of ≥ 5% after 1 month or ≥ 10% after 6 months from the start of treatment, is not uncommon in head and neck cancer patients. We aimed to assess the factors associated with critical weight loss during the treatment of oral cavity squamous cell carcinoma patients. Methods A retrospective cohort study was performed at the Aga Khan University Hospital, in Karachi, Pakistan, on 125 patients. Patients receiving adjuvant therapy were considered exposed, and the outcome was critical weight loss. Results The mean age of presentation was 46.9 ± 12.8 years in patients undergoing surgery and adjuvant therapy, with 119 (79.3%) of them being male and 31 (20.7%) female. One hundred and twelve patients (81.3%) developed critical weight loss at 6 months from the start of treatment, and the only significant variable associated with critical weight loss was the stage of the disease (p= 0.03). Conclusion A large proportion of patients with oral cancer developed critical weight loss requiring a need for intervention. The overall stage of the disease is a significant predictor of critical weight loss in patients undergoing treatment.

Frequency of Sensorineural hearing loss in chronic suppurative otitis media.

Chronic suppurative otitis media (CSOM) is defined as chronic otorrhea (i.e., lasting > 6-12 weeks) through a perforated tympanic membrane. It is generally associated with some degree of conductive hearing loss. However, recurrent ear infections due to perforated eardrum result in absorption of toxins and macromolecules into the cochlea leading to sensorineural hearing loss (SNHL). We planned to determine the frequency of sensorineural hearing loss in chronic suppurative otitis media. A descriptive cross-sectional study was conducted at Aga Kgan University Hospital, Karachi, from October 2013 to March 2014. Average threshold of speech frequencies was calculated via pure tone audiogram for both diseased and normal contralateral ear.A mean of >25db in diseased ear was labelled as positive case for SNHL. SNHL was reported in 64(52%) patients and the frequency was found to increase with increasing duration. Patients with CSOM should be counselled regarding the risk of developing SNHL if left untreated.

Squamous cell carcinoma of oral tongue in young patients - A 10 years tertiary care experience.

OBJECTIVE: To evaluate the clinical and pathological profile of young patients with squamous cell carcinoma of tongue. METHODS: The retrospective study was conducted at Aga Khan University Hospital, Karachi, and comprised record of patients <35 years presenting with squamous cell carcinoma of tongue between 2001 and 2011. Data was extracted from the electronic database of the hospital for site and age. Clinico-pathological variables were analysed using SPSS 20. RESULTS: Of the 29 patients, 17(58.6%) were men and 12(41.3%) were women. The overall mean age at presentation was 29.6+/-4.4 years. All patients (100%) had some sort of addiction, with 15(51.7%) having more than one addiction. Of the total, 20(68.9%) patients had moderately differentiated carcinoma. At presentation, 20(68.9%) had advanced stage (III-IV) disease. Surgery was the primary modality used in all the patients (100%). Median follow-up period was 36 months (range: 1-6 years). During follow-up, 7(24.1%) patients developed recurrence. CONCLUSIONS: Squamous cell carcinoma of the tongue was more commonly seen in males, and multiple addictions were a common risk factor.

Is There Any Benefit of Drain Placement on Postoperative Complications in Patients Undergoing the Sistrunk Procedure?

Introduction Same-day, outpatient Sistrunk procedure is commonly performed to manage thyroglossal duct cyst anomalies and may lead to postoperative complications. Surgical drains are placed to prevent complications, but recent observations show no advantage and rather increased health care costs and patient discomfort. Objective The study evaluated if drain placement in the Sistrunk procedure offers any benefit on postoperative complications. Methods A retrospective analysis of patient records having undergone same-day, outpatient Sistrunk procedure from 2004 to 2014 was done. Of 58 (38 male and 20 female) patients included, 38 did not have drains placed and the remaining 20 had drains placed. Mean and median age of patients was 18.1 and 13.5 years, respectively. Postoperative complications of patients with drains versus those without drains were statistically analyzed. Results Overall, about 10% of patients had hematoma/seroma (H-S), with 6.9% of patients needing aspiration for H-S; 3.4% had wound infections; and 1.7% had pus formation. No statistically significant differences in Sistrunk-related complications between patient groups (with drain or without drain) were seen using Fisher exact (two-sided) test: H-S (p = 0.08); need for aspiration (p = 0.29); wound infection (p > 0.05); and pus formation (p = 0.35). Chi-square test also did not show any significant difference in the groups in terms of number of follow-ups. Conclusion Surgical placement of a drain in the Sistrunk procedure does not seem to offer any advantage in terms of reducing common postoperative complications. Sameday Sistrunk procedure without any drain placement may be a safer alternative without necessitating hospitalization. More studies with larger sample size are needed for further substantiation.(AU)

Toluidine blue: yet another low cost method for screening oral cavity tumour margins in third world countries.

OBJECTIVE: To use toluidine blue intra-operatively to identify tumour involved margins after the removal of oral cavity squamous cell carcinoma, and to compare the findings with those of final histopathology. METHODS: The study was conducted at the Aga Khan University Hospital from December 1, 2009, to March 14, 2010, and comprised 56 consecutive patients with biopsy-proven squamous cell carcinoma of oral cavity regardless of grade and stage of tumour. Intra-operatively toluidine blue was used on the resected tumour margins and the staining patterns were assessed. Results were then compared with the final histopathology report. RESULTS: A total of 11(19.64%) margins were positive with toluidine blue staining out of which 8 (14.28%) were false positive. Sensitivity and specificity was found to be 100% and 84.9% respectively with a positive predictive value of 27.2%; a negative predictive value of 100%; and diagnostic accuracy of 85.71%. CONCLUSION: Toluidine blue costs only Rs25 (USD 0.30) and takes only 5 minutes for application and interpretation. It can be used with significant confidence in smaller lesions (T-l and T-II) as an alternative to frozen sections in developing countries where facilities are unavailable. Its use in larger lesions (T-lll and TIV) remains the topic of controversy and awaits a multi centre trial with a larger cohort.

Laryngeal tuberculosis presenting as laryngeal carcinoma.

Tuberculosis (TB) accounts for the highest number of mortalities among infectious diseases worldwide. Laryngeal TB is an extremely rare presentation of TB. It has many similarities to laryngeal carcinoma, one of the three most common cancers among males in the city, with an age standardized rate of 8.6. The associated risk factors of laryngeal carcinoma i.e. smoking, paan, betel nut usage and alcohol use also tend to be concentrated in the same demographic background as that of TB, creating a diagnostic dilemma. We present a case of granulomatous laryngeal TB, in a 40 year old male, with characteristic presenting features of laryngeal carcinoma i.e. persistent hoarseness and weight loss. He had no associated symptoms of fever, night sweats, cough or dysphagia, nor did he have any history of tobacco or irritant use. There was no history of tuberculosis (TB) contact. He was initially worked up for laryngeal carcinoma; however laryngoscopic biopsy revealed laryngeal TB. We present this case to emphasize the point that although primary laryngeal tuberculosis is a rarity, it must not be overlooked as a possibility when evaluating dysphonia and/or considering laryngeal carcinoma.

A comparative analysis of toluidine blue with frozen section in oral squamous cell carcinoma.

BACKGROUND: Surgical excision of the primary tumor with safe margins remains the mainstay of treatment for oral cavity squamous cell carcinoma (OSCC). The standard of care for assessment of intraoperative margins is frozen section histopathology. Unfortunately the facility is not available at most centers in limited resource countries. Toluidine blue, a metachromatic dye, has been well described in clinical identification of malignant and premalignant lesion in the oral cavity. Considering this we decided to explore intraoperative use of toluidine blue staining, in comparison with frozen sections, for the assessment of tumor-free margins. METHODS: After obtaining clearance from the in-house ethical review committee, a prospective study was conducted at Aga Khan University Hospital, Karachi, from August 15, 2009 to March 14, 2010. A sample of 56 consenting patients with biopsy-proven OSCC were included in the study, giving us 280 tumor margins. Margins were analyzed using toluidine blue staining and frozen section histopathology. A receiver operator curve (ROC) was then applied to compare assessment of margin status by toluidine blue and frozen section. RESULTS: Of the 280 examined margins 11 stained positive with toluidine blue, three were positive on frozen section biopsy, and three were positive on final histopathology. Toluidine blue staining had sensitivity and specificity of 100% and 97%, respectively. The diagnostic accuracy of toluidine blue was found to be 97.1% with a positive predictive value (PPV) of 27.2% and a negative predictive value (NPV) of 100%. CONCLUSIONS: Toluidine blue can be used as an effective screening modality for the assessment of intraoperative margins in resource limited environments and reducing the number of frozen section biopsies performed. Further by providing real-time clinical information within minutes it can reduce indirect costs such as operating room time. It may also be used as an ad hoc for frozen section biopsies where frozen section facilities are available.

Mucoepidermoid carcinoma of the base of tongue.

Mucoepidermoid carcinomas are thought to arise from the reserve cells of salivary gland ducts. Minor salivary glands are located all around the oral cavity and base of the tongue; however few cases of MEC of the base of the tongue have been reported in literature and no guidelines are available for its management. Here we would like to present the case of a 71 year old male with mucoepidermoid carcinoma of the base of the tongue successfully treated with surgical excision and neck dissection. Regular clinical follow up showed no signs of recurrence at 9 months post excision.

Management of allergic fungal sinusitis with postoperative oral and nasal steroids: a controlled study.

In patients with allergic fungal sinusitis, the mainstay of treatment remains surgical removal of allergic mucin and fungal debris. But as a single modality, surgery is associated with high rates of recurrence, so a number of adjunctive medical modalities have been tried, including postoperative corticosteroid therapy. We conducted a study of 63 patients with allergic fungal sinusitis who underwent endoscopic sinus surgery with or without postoperative steroid therapy. A group of 30 patients who had been treated prior to January 2000 had undergone surgery only; their cases were reviewed retrospectively, and they served as historical controls. Another 33 patients who were treated after June 2000 underwent surgery plus oral and nasal steroid therapy. All patients were followed for a minimum of 2 years. Recurrences were seen in 50.0% (15/30) of the no-steroid group and 15.2% (5/33) of the steroid group-a statistically significant difference (p = 0.008). The results of our study strongly support the use of steroids to control allergic fungal sinusitis and prevent its recurrence, and we recommend further study to identify the optimal dosage and duration of therapy.
