Prolonged Itraconazole Therapy as Sole Treatment for Patients with Allergic Fungal Rhinosinusitis.

BACKGROUND: Currently, the mainstay of treatment for allergic fungal rhinosinusitis (AFRS) is surgical debridement along with topical or systemic steroids. However, prolonged systemic steroid therapy comes with side effects and is also sometimes contraindicated. Systemic antifungals have been used earlier as an adjunct to steroids or in refractory cases, but they have not been used as the sole primary treatment. OBJECTIVE: To study the effectiveness of sole Itraconazole therapy in patients with AFRS by comparison of clinical, radiological, and biochemical parameters before and after treatment. METHODS: Thirty-four patients diagnosed with localized sino-nasal AFRS were recruited and started on the tablet Itraconazole 200 mg orally twice daily for 3 months with q2weekly monitoring of liver function tests. The baseline clinical, radiological, and biochemical parameters were then compared with those after completion of 3 months of Itraconazole therapy. RESULTS: There was significant difference between all the parameters-clinical: SNOT-22 score (p < 0.001) and Meltzer endoscopy score (p < 0.001), radiological: Lund-Mackay score (p = 0.004) and 20-point CT score (p = 0.002), and biochemical: serum total IgE (p < 0.001), Aspergillus-specific IgE (p < 0.001), and absolute eosinophil count (p < 0.001). The clearance of the disease was more in anterior sinuses than the posterior ones. CONCLUSION: Prolonged Itraconazole can be given as sole therapy in AFRS, especially in patients for whom steroids are contraindicated or in those who are awaiting surgery. It can result in symptomatic and radiological improvement, but surgery still remains the definitive treatment option for AFRS for complete clearance of disease.

La linfogammagrafía in vivo de los tumores del seno nasal identifica el ganglio retrofaríngeo y el nivel I como ganglios centinela predominantes / In-vivo lymphoscintigraphy of sinonasal tumors identifies retropharyngeal node and level I as predominant sentinel nodes

Objetivo Evaluar mediante linfogammagrafía in vivo y con detección SPECT/TC los patrones de drenaje linfático de los tumores del seno paranasal (SPN). Confirmar o rebatir la creencia de que el ganglio linfático retrofaríngeo (GLRF) se erige en el ganglio de drenaje índice para dichos tumores. Métodos Estudio de cohorte prospectivo realizado en pacientes con tumores del SPN no tratados previamente y sin evidencia clínico-radiológica de metástasis a nivel ganglionar. La linfogammagrafía se realizó mediante la inyección peritumoral de sulfuro coloidal marcado con [99m]TcO4 y asistida por endoscopia nasal. Las inyecciones se clasificaron como anteriores o posteriores en función de una línea vertical que pasaba por el orificio del seno maxilar. Resultados Se incluyeron 17 pacientes. La linfogammagrafía identificó satisfactoriamente 17 ganglios centinelas en 15 pacientes, y no pudo evidenciarlo (fracaso de la linfogammagrafía) en 2 pacientes. Se observó que los lugares predominantes de drenaje del ganglio centinela fueron el GLRF (n=8; 47%) y el nivel I (n=7; 42%). Se identificó drenaje ocasional en el ganglio periparotídeo (n=1) y en el nivel II (n=1). Se observó drenaje linfático contralateral en 2 pacientes (en el nivel I y GLRF, respectivamente). Las inyecciones anteriores drenaron predominantemente hacia el nivel I (6/8) y a GLRF (2/8), mientras que las inyecciones posteriores drenaron predominantemente a GLRF (6/7). El riesgo relativo de que el GLRF fuera identificado como ganglio centinela fue significativamente mayor en las inyecciones administradas posteriormente respecto a las administradas anteriormente (RR: 3,43; IC 95%: 1,0-11,8; p=0,05). Conclusión El GLRF es considerado un ganglio de drenaje frecuente asociado a los tumores del seno nasal, y merece su atención rutinaria en todos los casos de tumor del seno nasal (AU)

Objective To evaluate by in vivo lymphoscintigraphy and SPECT-CT imaging, the lymphatic drainage patterns of para-nasal sinus (PNS) tumours. To confirm or refute the belief of the retropharyngeal lymph node (RPLN) being the significant draining lymph node for such tumours. Methods Prospective cohort study conducted on previously untreated PNS tumours with no clinico-radiological evidence of lymph node metastasis. Lymphoscintigraphy undertaken by nasal endoscopic assisted peritumoral injection of 99mTc sulphur colloid. Injections were classified as anterior or posterior as per a vertical line along the maxillary sinus ostium. Results Seventeen patients were included. Lymphoscintigraphy successfully identified 17 sentinel nodes in 15 patients and was unsuccessful (lymphoscintigraphy failure) in 2 patients. Predominant sites of sentinel lymphatic drainage were noted to be the RPLN (n=8; 47%) and level I (n=7; 42%). Occasional drainage was identified at the peri-parotid node (n=1) and at level II (n=1). Contralateral drainage was noted in 2 patients (level I-1 and RPLN-1). Anterior injections drained predominantly to level I (6/8) and RPLN (2/8), while posterior injections drained predominantly to the RPLN (6/7). The relative risk of RPLN being identified as the sentinel node was significantly higher for posteriorly placed injections than for anteriorly placed injections (RR: 3.43; 95% CI: 1.0-11.8; P=.05). Conclusion The RPLN is noted as a frequent draining node for sino-nasal tumours and merits routine attention in all sino-nasal tumours. The radio-colloid SPECT-CT technique described here offers an excellent in vivo technique to further explore and validate the lymphatic drainage pathways of these tumours (AU)

Effect of surgical intervention on serum insulin-like growth factor 1 in patients with obstructive sleep apnoea.

OBJECTIVE: To evaluate the effect of surgical intervention on serum insulin-like growth factor 1 levels in patients with obstructive sleep apnoea. METHODS: A prospective study was conducted in a tertiary care hospital of adult patients with obstructive sleep apnoea for whom continuous positive airway pressure therapy failed or was refused. All patients underwent polysomnography and serum insulin-like growth factor 1 evaluation pre-operatively and at three months post-operatively. The site of surgery was determined using Müller's manoeuvre and ApneaGraph AG 200. RESULTS: Fifteen patients were included with a mean age of 38 years: 11 males and 4 females. The mean pre-operative Apnoea-Hypopnoea Index using polysomnography was 53.7 events per hour, and the mean post-operative Apnoea-Hypopnoea Index at three months was 15.3 events per hour (p = 0.0001). The mean pre-operative serum insulin-like growth factor 1 was 160.2 µg/l, while the mean post-operative value was 236.98 µg/l (p = 0.005). CONCLUSION: In adult patients with obstructive sleep apnoea for whom continuous positive airway pressure therapy fails, site-specific surgical intervention to treat the obstruction leads to an increase in serum insulin-like growth factor 1 levels.

Intracellular cytokine expression in invasive fungal sinusitis and its impact on patient outcome.

BACKGROUND: Cell-mediated immunity plays an important role in host defence against fungal pathogens, regulated by differentiation of lymphocytes towards T-helper 1 or 2 cells. This study reports intracellular cytokine variation in terms of invasive fungal sinusitis type and outcome. METHODS: The mononuclear leukocytes of 15 patients with invasive fungal sinusitis (mucormycosis in 8, aspergillus in 7) were stained with antibodies against intracellular cytokines, after fungal antigen stimulation and culture, and immunophenotyped. Patients were followed up for six months, with clinical course categorised as improvement, worsening or death. RESULTS: The mean percentages of mononuclear cells producing interleukins 4, 5, 10 and 12, and interferon-γ, in the mucormycosis group were 0.575, 0.284, 8.661, 4.460 and 1.134, respectively, while percentages in the aspergillosis group were 0.233, 0.492, 4.196, 4.466 and 1.533. Cells producing interleukin 4 and 10 were higher in the mucormycosis group, while those producing interleukin-12 and interferon-γ were lower. Cells producing interleukins 4 and 12 were higher in patients with a poor outcome (p-values of 0.0662 and 0.0373, respectively), while those producing interferon-γ were lower (p = 0.0864). CONCLUSION: Adaptive cell-mediated immunity is expressed differently in two categories of invasive fungal sinusitis, and the cytokine expression pattern is related to prognosis.

Facial neuritis in coronavirus disease 2019 associated mucormycosis: study on clinico-radiological correlates.

OBJECTIVE: To elucidate the aetiopathogenesis of facial neuritis in coronavirus disease 2019 associated mucormycosis. METHODS: A retrospective review was conducted of coronavirus disease 2019 associated mucormycosis patients who presented with peripheral facial nerve palsy from January 2021 to July 2021. The clinico-radiological details of four patients were assessed to examine the potential mechanism of facial nerve involvement. RESULTS: Serial radiological evaluation with contrast-enhanced computed tomography and contrast-enhanced magnetic resonance imaging revealed infratemporal fossa involvement in all cases, with the inflammation extending along fascial planes to reach the stylomastoid foramen. Ascending neuritis with an enhancement of the facial nerve was demonstrated in all cases. CONCLUSION: The likely explanation for facial palsy in patients with coronavirus disease 2019 associated mucormycosis, backed by radiology, is the disease abutting the facial nerve at the stylomastoid foramen and causing ascending neuritis of the facial nerve.

Temporal bone meningoencephaloceles and cerebrospinal fluid leaks: experience in a tertiary care hospital.

OBJECTIVE: To recount experience with cerebrospinal fluid otorrhoea and temporal bone meningoencephalocele repair in a tertiary care hospital. METHOD: A retrospective review was conducted of 16 cerebrospinal fluid otorrhoea and meningoencephalic herniation patients managed surgically from 1991 to 2016. RESULTS: Aetiology was: congenital (n = 3), post-traumatic (n = 2), spontaneous (n = 1) or post-mastoidectomy (n = 10). Surgical repair was undertaken by combined middle cranial fossa and transmastoid approach in 3 patients, transmastoid approach in 2, oval window plugging in 1, and subtotal petrosectomy with middle-ear obliteration in 10. All patients had successful long-term outcomes, except one, who experienced recurrence after primary stage oval window plugging, but has been recurrence-free after second-stage subtotal petrosectomy with middle-ear obliteration. CONCLUSION: Dural injury or exposure in mastoidectomy may lead to cerebrospinal fluid otorrhoea or meningoencephalic herniation years later. Congenital, spontaneous and traumatic temporal bone defects may present similarly. Middle cranial fossa dural repair, transmastoid multilayer closure and subtotal petrosectomy with middle-ear obliteration were successful procedures. Subtotal petrosectomy with middle-ear obliteration offers advantages over middle cranial fossa dural repair alone; soft tissue closure is more robust and is preferred in situations where hearing preservation is not a priority.

Quality of life outcome measures using University of Washington questionnaire version 4 in early T1/T2 anterior tongue cancers with and without radiotherapy: A cross-sectional study.

CONTEXT: To evaluate the quality of life (QOL) outcome measures in disease-free survivors of pathological T1/T2 tongue cancers and to compare QOL in patients treated with only surgery and with adjuvant treatment. SETTINGS AND DESIGN: Cross-sectional survey. PATIENTS AND METHODS: All pathological T1/T2 anterior tongue cancer cases with follow-up from January 2011 till December 2015, who had locoregionally controlled disease with a minimum disease-free survival period of 1 year, were included in the study. RESULTS: A total of 36 patients, 28 are males and 8 are females with an age range of 24-66 years (median age of 43) were enrolled in the study. The patients were divided into two groups with (n = 26) and without adjuvant postoperative radiotherapy (RT) (n = 10) and the University of Washington-QOL questionnaire version 4 for physical and social domains, global questions and three important domains were analyzed. On the physical and social domain scores, the surgery-alone group outscored the combined modality group on all scales and the differences were statistically significant for specific physical domains such as saliva (0.0001), taste (P = 0.0001), chewing (P = 0.0004), swallowing (P = 0.0026), and social domains such as mood (0.0001), pain (P = 0.0001), and shoulder function (P = 0.0061). The overall global QOL scores were also better for the surgical group compared with group which received adjuvant RT but was not statistically significant. All patients chose saliva as their top priority domain in the group which received radiation, and 60% chose "swallowing ability" as the preferred top priority domain in the only surgical group. CONCLUSIONS: Although locoregional control and disease-free survival are the major treatment-related endpoints for cancer management, QOL outcome measures have to assess to determine the impact of a treatment modality on patients well-being and for better rehabilitation of cancer-free patients.

Surgery for vertigo: 10-year audit from a contemporary vertigo clinic.

OBJECTIVE: To present the profile of patients undergoing surgical treatment for vertigo at a contemporary institutional vertigo clinic. STUDY DESIGN: A retrospective analysis of clinical charts. METHODS: The charts of 1060 patients, referred to an institutional vertigo clinic from January 2003 to December 2012, were studied. The clinical profile and long-term outcomes of patients who underwent surgery were analysed. RESULTS: Of 1060 patients, 12 (1.13 per cent) were managed surgically. Of these, disease-modifying surgical procedures included perilymphatic fistula repair (n = 7) and microvascular decompression of the vestibular nerve (n = 1). Labyrinth destructive procedures included transmastoid labyrinthectomy (n = 2) and labyrinthectomy with vestibular nerve section (n = 1). One patient with vestibular schwannoma underwent both a disease-modifying and destructive procedure (translabyrinthine excision). All patients achieved excellent vertigo control, classified as per the American Academy of Otolaryngology - Head and Neck Surgery 1995 criteria. CONCLUSION: With the advent of intratympanic treatments, surgical treatments for vertigo have become further limited. However, surgery with directed intent, in select patients, can give excellent results.

Hazardous complications of animate foreign bodies in otology practice.

BACKGROUND: Animate foreign bodies in the ear are frequent occurrences in otology practice. Such foreign bodies may lead to hazardous complications. METHOD: This paper describes a retrospective study of six patients with a recent history of an insect in the ear who presented with various complications following intervention received elsewhere. RESULTS: An insect was retrieved from the external auditory canal in four cases and from the antrum in two cases. The patients presented with progressive otological complications: two patients who presented with orbital apex syndrome and cavernous sinus thrombosis succumbed to the disease; three patients suffered sensorineural hearing loss; and two patients had persistent facial palsy. One patient with sigmoid sinus thrombosis, who presented early, experienced complete recovery. CONCLUSION: Insects in the ear can lead to hazardous complications. Animate foreign bodies should preferably be managed by a trained otologist, even in an emergency setting. Patients with delayed presentation and complications have a guarded prognosis.

Evaluation of epithelial proliferation in paediatric and adult cholesteatomas using the Ki-67 proliferation marker.

INTRODUCTION: The aggressiveness of cholesteatoma in children compared with adults is well known. However, the factors influencing the poorer prognosis of paediatric cholesteatoma are not well understood. This study compared the proliferative potential of paediatric cholesteatoma with that of adult cholesteatoma, using Ki-67 as a proliferation marker. METHODS: A prospective study of 67 patients with aural cholesteatoma was performed. Thirty-eight adult and 29 paediatric cases were evaluated using clinical parameters including bone erosion, complications and extent of disease. A surgical specimen underwent histological evaluation and measurement of the proliferation index using Ki-67 labelling. Normal epithelium from a control group was also examined. RESULTS: Cholesteatoma epithelium has a greater rate of proliferation than normal skin. There were however no statistical differences between the paediatric and adult cholesteatoma groups in terms of clinical behaviour or proliferation potential. Paediatric cholesteatoma was similar to adult cholesteatoma in terms of complications, bone erosion and disease spread. CONCLUSION: Cholesteatoma is a disorder of epithelial proliferation. Although postulated to be more aggressive in children than adults, this study found no clinicopathological differences between paediatric and adult cases.
