Diagnostic Difficulties

Schwannomas (neurilemmomas) are infrequent, benign mesenchymal neoplasms that pose considerable preoperative diagnostic difficulties. Schwannomas of the submaxillary gland are even less common, with only few cases reported in the literature to date. The present study describes a male with a right submaxillary tumor for the past 9 years; the histopathological study diagnosed schwannoma - no preoperative evaluation having been able to establish the diagnosis.

<p class="abstract"><strong>Background:</strong> The varied symptomatology and diagnostic difficulties pose a great challenge to the Otorhinolaryngologists in treating chronic rhinosinusitis. Both diagnostic nasal endoscopy and computed tomography (CT) has been used to analyse the pathological/anatomical changes associated with chronic rhinosinusitis. Various studies have been done to evaluate the efficacy of both these methods to analyse the changes associated with chronic rhinosinusitis. In this study, the authors contemplate to determine which one is better as a preoperative diagnostic tool.</p><p class="abstract"><strong>Methods:</strong> In this study 30 patients (60 sides) suffering from chronic rhinosinusitis underwent functional endoscopic Sinus Surgery after being thoroughly evaluated by diagnostic endoscopy and CT scan. The various factors affecting the sinus drainage were analysed and compared between each modality.  </p><p class="abstract"><strong>Results:</strong> The findings of diagnostic endoscopy correlated very well with the operative findings except for conditions where there was severe anatomic or pathologic obstruction which hampered visualisation. Extent of disease in each sinus is very well recognised on CT.</p><p class="abstract"><strong>Conclusions:</strong> Both diagnostic endoscopy and CT are important preoperative evaluation tools in detecting anatomic variations or pathologic changes within sinuses, although for the surgeon, the operative findings remain the gold standard in the management of the disease.</p>

Needle Aspiration Cytology

Objective: To evaluate the role of Fine Needle Aspiration Cytology in the preoperative diagnosis of malignancy in parotid and submandibular gland neoplasm. Methods: This cross sectional study on 50 cases was conducted in the Department of Otolaryngology and Head-Neck Surgery of Sir Salimullah Medical College Mitford Hospital and Dhaka Medical College Hospital from January’2009 to June 2010. Results: Fine needle aspiration cytology findings of our all 50 cases were compared with postoperative histopathological reports. Out of the 50 cases, in 36(72%) cases of benign neoplasm and 7(14%) cases of malignant neoplasm, pre-operative FNAC findings and post operative histopathological findings were same. In 7 cases, FNAC and post operative histopathological findings did not matched. These were 2 (4%) false positive and 5 (10%) false negative result.In our study sensitivity of FNAC for reporting malignancy was 58.33%, specificity to rule out malignancy was 94.73% and overall accuracy in detecting malignant tumour was 86%. Positive predictive value and negative value were 77.77% and 87.80% respectively. It can be concluded that fine needle aspiration cytology is a safe, cheap and useful preoperative diagnostic tool in the diagnosis of malignancy in parotid and submandibular gland, but as fine needle aspiration cytology partly depends on operator skill, it may give false negative and false positive result. Conclusion: FNAC is a useful preoperative diagnostic tool for malignant parotid and submandibular glands with high specificity and sensitivity.

Growing Mass

We report the case of a 10-year-old girl with a painless slowly growing mass that had developed over the course of 2 years in the left submandibular area. Physical examination revealed a firm painless submandibular mass with no other associated signs. Ultrasound graphics were in favor of a sebaceous cyst. Fine-needle aspiration and magnetic resonance images (MRI) concluded to a pleomorphic adenoma of the submandibular gland. The patient underwent left submandibulectomy. Histopathological examination confirmed the diagnosis of pleomorphic adenoma arising from the submandibular gland. The postoperative course was uneventful. Pleomorphic adenoma of the submandibular gland represents a diagnostic and therapeutic dilemma in children. Preoperative evaluation, including MRI and fine-needle aspiration, is recommended. Total submandibulectomy is also recommended to minimize recurrences and to avoid malignant transformation.

Genetic Profiles

“Emergence” of infectious disease agents in humans, domestic animals and wildlife during the past 20 years has been widely described. Perception of emergence derives largely from the application of improved identification methods, including refinements in molecular, serologic, and microscopy technologies that enable researchers to monitor species migration with greater sensitivity. The reality of emergence comes from shifts in genetic profiles and from influences of ecological changes often brought about by human interventions designed for economic or quality-of-life gains, and ecologic management. CDC has frequent involvement with many outbreaks caused by various infectious disease agents, some of which may be considered emerging. Notable unusual agents include filoviruses (Fig. 1) and hantaviruses (Fig. 2). More typically encountered agents include caliciviruses (Fig. 3) and influenza viruses (Fig. 4). Recently, threats of national and international bioterrorism have added to CDC's responsibilities for prompt identification of infectious agents.

Glial Heterotopia

Objective: To report a case of ectopic brain tissue in the nasopharynx; discuss the differential diagnoses for and management of, this unilateral nasal mass in a pediatric patient, and describe the diagnostic difficulties and eventual treatment. Methods: Study Design:      Case Report Setting:                 Tertiary Government Hospital Participant:                      One   Results:  A 13-year-old boy consulted with an obstructing mass in the nasopharynx and severe muscle wasting, weight below his age and concurrent anemia.  CT-scan revealed a soft-tissue mass occupying a maxillary sinus and nasopharynx consistent with an antrochoanal polyp.  Initial biopsy revealed a papilloma, but the clinical picture warranted preoperative preparations for a possible vascular tumor such as juvenile angiofibroma.  Transpalatal excision and final histopathology yielded nasal glial heterotopia.  Conclusion: When confronted with a unilateral nasal mass in a pediatric patient, aside from the usual considerations, embryologic anomalies particularly those of the intracranial protrusion variety should be strongly considered. Scrupulous preoperative evaluation and sufficient diagnostic modalities must be pursued in order to arrive a correct diagnosis, treatment plan and prevent possible complications especially those related to intracranial communication.

Bariatric Metabolic Surgery

The incidence of obesity is rising worldwide and so are its comorbidities: type-2 diabetes mellitus (T2DM), dyslipidaemia, hypertension, cardiovascular disease, sleep apnoea, and depression. Bariatric/metabolic surgery has established itself over the past several years as an effective treatment not only for morbid obesity but also for its associated morbidities. The effects of bariatric/metabolic surgery on depression are controversial, with some studies showing improvement and others demonstrating a worsening. However, a major drawback of these studies is that they do not compare patients with the same baseline psychiatric disorders. In fact, mild to severe depressive symptoms are observed in most candidates for bariatric/metabolic surgery. Preoperative evaluation of the patient’s mental state would enable identification of the appropriate interventions, enhancing long-term compliance and weight maintenance. It could also leverage psychological support in case the patient’s disorder relapses postoperatively. Preoperative evaluation should detect potential psychological contraindications to surgery, such as severe eating disorders.

Vascular Structures

A 35-year-old woman presented with a progressively increasing swelling over the left side of the upper part of the neck for the past 8 months with no associated pain over the swelling. On examination, a non-tender, firm, well-defined, oval swelling of size 3×2 cm was palpable in the left submandibular region that was mobile, non-pulsatile and free from the overlying skin and the underlying muscle. Ultrasonography revealed a bilobed heteroechoic lesion in the left submandibular region with internal vascularity and multiple macrocalcification within it. During the procedure for surgically excising the swelling, we found that it was separate from the gland and vascular structures, had a sinus tracking over and around the left submandibular gland extending beyond the angle of mandible up to the root of a decayed left lower second molar tooth.
