Experimental study on penetration characteristic of submerged steam jet in quiescent water
Authors: Sun L. , Shi E.-B. , Wang Ch. , Hao R. 
Published: April 2019

AbstractThe direct contact condensation is an effective way to rapid depressurization for light water reactor, such as pressure suppression pool, for which the characteristic of steam plume is a key parameter to evaluate the efficiency of depressurization. In this paper, a series of visualization experiments are described which investigate the characteristic of steam plume, the influence of jetting direction, air mass fraction, water temperature, diameter of jet on the steam plume were analyzed. The results show that, the dimensionless steam plume length increased with the increase of inlet pressure and water temperature for pure steam submerged jet, a correlation was set up to predict the dimensionless penetration length and the predicted errors were within the band of ±15%. Furthermore, the penetration length decreased with the rise of air mass fraction due to buoyancy force, the penetration length increased with the increase of inlet pressure, and the jet penetration length for vertical jet is longer than horizontal jet about 25% at the same inlet pressure and air mass fraction.
Inflammatory Pseudotumor of an Orbito-Maxillary Mass Masquerading as a Malignancy
Authors: Da Silva Maria Cristina C. , Romualdez Joel A. , Martinez Norberto A. 
Published: April 2019

Objective: To present a case of a benign orbito-maxillary tumor behaving as an invasive,
expansive malignancy.

Design: Case report

Setting: A tertiary care hospital in Metro Manila

Patient: A 4-year-old boy with a seven month history of right orbito-maxillary mass, proptosis and epiphora.
Result: A series of biopsies were done before a definite diagnosis was made due to inconsistencies in the histopathologic findings, clinical picture, and the radiologic presentation of the case. After diagnosis, appropriate intervention resulted in a dramatic decrease in the size of the mass. At present, the patient is disease-free and asymptomatic.

Conclusion: Histopathologic diagnosis of Inflammatory Pseudotumor is difficult and differentiating it from malignant tumors is often a concern for otolaryngologists and pathologists. In spite of an initial malignant biopsy result, the combination of clinical signs and symptoms and radiologic findings of an infiltrative mass lesion, should not discount the possibility of a benign entity such as Inflammatory Pseudotumor for which treatment is conservative.

The Correlation of Results between Pure Tone Audiometry and the Virtual Audiometer: A Simulated Air-Conduction Clinic-based Audiometer
Authors: Javellana Anne Elizabeth M. , Casile Ray U. 
Published: April 2019

The virtual audiometer (VA) is a software application that simulates a pure tone audiometer by delivering tones of different frequencies and intensities by air conduction.

Objective: To determine correlation between hearing thresholds measured by virtual and pure tone audiometry and degree of agreement in their hearing loss classification.

Methods: Analytic, cross-sectional study set in a Philippine tertiary institution. Subjects were recruited from the outpatient department in September 2005 and comprised of cooperative, clinically normal and abnormal hearing individuals. Thirty-two subjects made 64 total ears tested (n=64), giving 0.90 correlation at 0.05 level of significance (a) (p = 0.05) and 99% power. Each subject underwent pure tone and virtual audiometry, the average thresholds calculated, and degree of hearing loss categorized according to classification by the World Health Organization (WHO). Results were not revealed until both examinations were completed. Data were stratified by frequency and compared by Pearson’s correlation, while Kappa statistics determined degree of agreement between WHO grades of hearing impairment.

Results: Average age was 40.2 years, with 20-80 year range and 18.5 years standard deviation. Nine subjects were male while 23 were female (M:F ratio = 0.39). Of 64 ears, 34 were clinically normal and 30 abnormal. Pearson’s correlation demonstrated significant positive correlation between virtual and pure tone thresholds with 99% confidence at 0.05 level of significance. Kappa statistics also showed significant degrees of agreement in WHO grades by both instruments, meaning VA will probably categorize hearing loss in the same manner as pure tone audiometry.

Conclusion: A strong positive correlation exists between hearing thresholds measured by virtual and pure tone audiometry with a significant degree of agreement in hearing loss classification. This supports the possibility of using the virtual audiometer as a clinic-based, air-conduction audiometer for screening and monitoring. When used in conjunction with other examinations, valuable information on over-all integrity of the audiologic system may be ascertained.

Collar Size as Predictor of Obstructive Sleep Apnea
Authors: Veloro Lyra V. , Sarte Michael Alexius A. , Castañeda Samantha S. 
Published: April 2019

Objective: This study focuses on evaluating the relationship between physical findings, particularly collar size and Body Mass Index (BMI), and polysomnographic parameters in male patients seen at a Sleep Disorders Laboratory, suspected to have Obstructive Sleep Apnea (OSA).

Methods:
Design: Cross-sectional study
Setting: Academic tertiary private hospital
Participants: Charts of 149 adult male patients referred for polysomnography between July 1, 2005 and June 30, 2006 were reviewed. Height, weight, and external neck circumference measurements were obtained. The data from polysomnography results were noted and correlated with the physical measurements.

Results: The mean collar size for the OSA group was 42.03 cm with a mean BMI of 29.14 while the mean collar size for the normal group was 39.05 cm with a mean BMI of 25.36. A significant difference was noted in both the collar size and body mass index (BMI) between the OSA group and the normal group (p<0.005). Results showed a significant correlation between collar size and BMI. Collar size and BMI measurements were also correlated with increasing severity of sleep apnea in the OSA group. The ³40 cm collar size among male adults with symptoms of OSA was 80% sensitive and 67% specific with a positive predictive value of 94% in predicting true OSA.

Conclusion: This study suggests that the external neck circumference and the degree of obesity determined through BMI measurement may be important predictors of sleep apnea in adult Filipino males suspected to have OSA. Given the high probability of having true OSA in symptomatic male adults with a collar size ³ 40 cm, outright definitive management may be opted for in these patients, while those with a collar size < 40 cm may need to undergo further confirmatory tests.

Primary Lymphoma of the Temporal Bone: The First Locally Reported Case
Authors: Uy Julie Ann G. , Jugo Jose Carlos Z. , Acuin Jose M. 
Published: April 2019

Objective: To report a case of primary non-Hodgkin’s T-cell lymphoma in the temporal bone in a pediatric patient, discussing clinical presentation and course, diagnostic evaluation and management in the light of published literature.
Methods:
Design: Case report
Setting: Private tertiary university hospital
Patient: One
Results: An 8-year-old female with a 10-month history of otalgia and ipsilateral headache developed facial paralysis, unresponsive to topical otic drops and oral antibiotics. Imaging revealed mastoid sclerosis, tegmental and ossicular erosions, and an attico-antral mass which was excised through exploratory tympanomastoidectomy. Final histopath following immunohistochemical corroboration was T-cell lymphoma.
Conclusion: Primary malignant lymphoma of the temporal bone may initially present with otalgia and headache unresponsive to conventional medical management. Ominous signs like facial paralysis should heighten the suspicion of malignancy warranting prompt imaging of the temporal bone. Histopathologic evaluation of all mastoidectomy specimens should be mandatory especially in children, and special stains performed as needed. Patients with T cell NHL should undergo chemotherapy and may warrant closer follow up for tumor recurrence and disease progression.

Pediatric Endoscopic Sinus Surgery in a Tertiary Government Hospital: Patient Profile and Surgical Indications
Authors: David Michael Joseph C. , Vicente Gil M. , Chua Antonio H. 
Published: April 2019

Objective: To describe the clinical and demographic profile of patients who underwent pediatric Endoscopic Sinus Surgery (ESS), and the indications for which the procedure was performed.
Methods:
Design: Cross-sectional Study
Setting: Tertiary Government Hospital
Subjects: Using the medical record registry, all patients below 18 years of age who underwent ESS under the Department of Otorhinolaryngology – Head and Neck Surgery of a tertiary government hospital in Metro Manila between December 31, 1999 and January 1, 2008 were reviewed. The age, sex, clinical presentation, and indications for doing ESS, and extent of surgery done were described. The Lund MacKay Grading for nasal polyposis and Scoring for sinusitis were also applied and cross-referenced.
Results: Twenty-seven children aged 7 to 17 years underwent ESS. The mean age was 12.9 years, with most (15 patients) belonging to the adolescent age group (13-17 years). Male to female ratio was 1.45:1. The mean interval from onset of symptoms to the first outpatient consultation was 1.5 years; the most common presenting symptoms were nasal obstruction (85.2%) and discharge (59.3%).
All of the patients who underwent pediatric ESS had chronic rhinosinusitis: either with nasal polyposis (85.2%), an antrochoanal polyp (11.1%), or both (3.7%). The Lund Mackay Grading for nasal polyps and sinusitis scores were cross-referenced: patients with larger, grade III nasal polyps tended to have more extensive sinus disease than those with grade II polyps. On their first consultation, the patients tended to present with extensive nasal polyp and sinus disease, indicating the need for surgery.
All patients with CRS and nasal polyposis underwent polypectomy with ethmoidectomy, uncinectomy and maxillary antrostomy, with additional frontal sinusotomy for a 17 year old male and a 17 year old female, both with grade 3 polyposis. The three patients who had antrochoanal polyps underwent polypectomy with uncinectomy and maxillary antrostomy. There were no operative complications such as cerebrospinal fluid leak and orbital injury reported.
Conclusion: Most of the patients who underwent pediatric ESS were older children who were brought for consultation with long-standing, extensive nasal polyp and sinus disease or with antrochoanal polyps, necessitating surgical management. Patients with larger polyps tended to have more extensive sinus disease. They all underwent conservative surgery, with extent of the procedure limited to the extent of the disease present. Efforts to raise public awareness about chronic rhinosinusitis and nasal polyposis in children may result in seeing such cases at an earlier, conservatively treatable stage

Extramedullary Plasmacytoma of the Nasopharynx: A Rare Tumour with 7-Year Follow Up
Authors: Azman Mawaddah , Gendeh Balwant Singh , Ali Siti Aishah Mat 
Published: April 2019

Objective: To report a case of extramedullary plasmacytoma, a rare localized tumour involving
the head and neck region in a 56-year -old gentleman.

Methods:
Design: Case Report
Setting: Tertiary University Referral Center
Patient: One

Result: The patient presented with a 5-month history of right-sided nasal obstruction and intermittent epistaxis in 2003. Nasal endoscopy revealed a friable, dark red mass arising from the roof of the nasopharynx, occluding the right choana. No invasion of adjacent tissues or cervical lymphadenopathy was evident. A biopsy of the mass was diagnosed as plasmacytoma. Serum and urine electrophoresis failed to detect any monoclonal bands. All other screening tests to rule out multiple myeloma were negative. These findings confirmed the diagnosis of extramedullary plasmacytoma. He recieved radiotherapy to the nasopharynx of 50 Gy for a total of 23 fractions. No recurrence was noted at 7-year follow-up.

Conclusion: Extramedullary plasmacytoma of the nasopharynx represents a tumour with good prognosis but requires long term follow up in anticipation of local recurrence and progression to Multiple Myeloma.

Keywords: extramedullary, plasmacytoma, nasopharynx

Sinonasal Mucosal Melanoma: An Enigma
Authors: Ullah Hidayat , Baig Mirza Qaisar 
Published: April 2019

Objective: To report two cases of mucosal melanoma of the sinonasal cavity from India and
review the literature emphasizing current important clinical and biologic aspects of this tumor.

Methods:
Design: Case Report
Setting: Tertiary Public Referral Hospital
Patients: Two

Results: Two patients presenting with progressive unilateral nasal obstruction over three to six
months, respectively, were diagnosed to have sinonasal mucosal melanoma. The mass involved
the nasal cavity and maxillary antrum in both patients. The first patient deferred radiotherapy for
four months until pulmonary metastasis became evident, necessitating palliative chemotherapy;
the second patient underwent surgical excision and radiotherapy.

Conclusion: In spite of aggressive therapy, the prognosis for people with mucosal melanoma
is extremely poor. Surgery remains the mainstay of treatment, although adjuvant radiation
therapy has recently had an increasing role in the treatment of mucosal melanoma. A clear
understanding of the pathophysiology of this disease may yield more specific immunotherapy
and chemotherapy techniques. A multicenter prospective study is required to objectively assess
the optimal treatment regimen.

Undifferentiated Nasopharyngeal Malignancy with Immunohistochemical Features of Diffuse Large B Cell Lymphoma and Undifferentiated Carcinoma: A Collision Tumor?
Authors: Gelera January E. , Martinez Norberto V. 
Published: April 2019

Objective: To describe an unusual presentation of undifferentiated nasopharyngeal malignancy with immunohistochemical features of both diffuse B-cell lymphoma and undifferentiated carcinoma.Methods: Design: Case Report Setting: Tertiary Private University Hospital Patient: OneResults: A 49-year-old female whose initial nasopharyngeal biopsy interpretation was diffuse large B-cell lymphoma underwent three cycles of Rituximab, Cyclophosphamide, Hydroxydaunomycin, Oncovin and Prednisone (R-CHOP). Post-chemotherapy ComputedTomography (CT) scan of the nasopharynx revealed no change in tumor size or appearance. Repeat nasopharyngeal (NP) biopsy findings suggested an epithelial tumor lineage or post chemotherapy reactive mucosal epithelial cells. No residual lymphoma was noted and immunostaining was positive for cytokeratin. The patient underwent 35 fractions of radiotherapy. Re-evaluation by Magnetic Resonance Imaging (MRI) with contrast after four months showed significant tumor shrinkage. Repeat NP biopsy revealed necrotic tissues with foci of high-grade squamous cell carcinoma. Two months after the biopsy, repeat MRI with contrast of the nasopharynx and neck showed increase in the bulk of the nasopharyngeal tumor with inferior extension to the level ofthe orophaynx and possible contralateral involvement. A nasopharyngectomy via left maxillary swing was performed and the final histopathology was undifferentiated carcinoma.Conclusion: Undifferentiated malignancies of the nasopharynx may contain lymphoma or carcinoma and rarely, both lineages in coexistence. In such cases, the possibility of a collision tumor should be considered. Immunohistochemical distinction is important for treatment and prognostication.Keywords: nasopharyngeal carcinoma, undifferentiated tumor, undifferentiated carcinoma, nasopharyngeal lymphoma, collision tumors, immunohistochemistry, Diffuse large B-cell lymphoma,secondary malignancy
Juvenile Angiofibroma Protruding from the Nasal Cavity
Authors: Fong Voon Hoong , Yunus Mohd Razif Mohamad 
Published: April 2019

Objective: To describe a case of juvenile angiofibroma with unusual protrusion out of the nasal cavity, and its management with surgery and radiotherapy.
Methods:
Design: Case Report
Setting: Tertiary Public Referral Centre
Patient: One
Results: A 17-year-old gentleman presented with a huge tumor protruding from his left nostril, diagnosed with juvenile angiofibroma stage IIIA by MRI and angiography. Following successful pre-operative embolization, the protruding mass was ligated and truncated, followed by surgical resection via external approach. Post-operative residual tumor was treated with adjuvant radiotherapy. There was no evidence of recurrence after 9 months.
Conclusion: A high index of suspicion is of paramount importance in the diagnosis of JA and avoids the possibility of an unwarranted biopsy, which could spell disaster. The most useful tools for diagnosis are MRI and arterial angiography. Treatment is primarily surgical. Irradiation therapy has been reported to achieve satisfactory outcomes, especially for unresectable residual disease and/or intracranial extension, where total surgical resection is unlikely to be attained without unacceptable morbidity.
Keywords: juvenile angiofibroma, juvenile nasopharyngeal angiofibroma, head and neck tumor.
Carcinoma ex Pleomorphic Adenoma in the Parapharyngeal Space
Authors: Pal Sudipta , Pati Sampurna , Saha Somnath , Saha Vedula Padmini 
Published: April 2019

Objective: To present a case of carcinoma ex pleomorphic adenoma in the parapharyngeal
space and discuss its management.

Methods:
Design: Case Report
Setting: Tertiary Government Teaching Hospital
Subjects: One

Results: A 40-year-old male patient with dysphagia for three months and a left-sided mucosa-covered oropharyngeal mass was found to have a prestyloid parapharyngeal lesion on CT Scans. Fine Needle Aspiration Cytology (FNAC) revealed a pleomorphic adenoma. With a past history of parapharyngeal pleomorphic adenoma excised transorally three years before, the present mass was excised by mandibular swing approach. Post-operative recovery was uneventful, but the final histopathological report was carcinoma ex pleomorphic adenoma.

Conclusion: Malignant transformation should be suspected in recurrent salivary tumors in the parapharyngeal space. Provided there was truly no pre-existing malignant focus in the originally-excised tumor, and that early recurrence was not due to inadequate initial excision, this patient had a rare condition where the same tumor underwent malignant transformation within 3 years only. To the best of our knowledge, such an early transformation to malignancy of a minor salivary gland tumor of the parapharyngeal space has not been reported in the English literature.
