Influence of speech aid prosthesis with speech therapy on speech outcomes in adult patients with persisting velopharyngeal insufficiency: A retrospective analysis.

STATEMENT OF PROBLEM: Prosthetic intervention with a speech aid prosthesis (SAP) along with speech therapy has been reported to improve speech outcomes in patients with persisting velopharyngeal insufficiency (VPI). However, little is known regarding the impact of this treatment on different speech parameters over time in adult patients with VPI. PURPOSE: The purpose of this retrospective study was to evaluate the change in speech parameters after rehabilitation with an SAP and speech therapy in adult patients with VPI using subjective and objective tests. MATERIAL AND METHODS: Patients above 16 years of age who had received prosthetic treatment for VPI and had complete speech assessment records between 2017 and 2020 were included in the analysis. After completion of the prosthetic treatment, speech therapy comprising 2 sessions per week of 45 minutes was provided by a speech pathologist. Speech evaluation was performed using tests that included speech intelligibility calculation, nasal pinch test, audible nasal air emissions, acoustic analysis, and the nasalance check. Assessments were done at 4 time intervals: T0: without an SAP; T1: 1 week with an SAP; T2: 1 month with an SAP; and T3: 3 months with an SAP. A descriptive analysis was followed by a comparison between groups using the Friedman test for subjective assessments and repeated measures ANOVA for objective tests (α=.05). RESULTS: Of 10 individuals who had received an SAP, 5 participants, 2 men and 3 women with a mean age of 38 years were included in the analysis. Statistically significant improvement in mean scores was observed from T0 to T3 concerning speech intelligibility (P<.001), hypernasality (P<.001), audible nasal air emission (P<.001), mean fundamental frequency (P=.034), shimmer percentage (P=.004), and nasalance (P=.004). Improvement in jitter percentage was not statistically significant (P=.218). CONCLUSIONS: An SAP along with speech therapy should be considered as a conservative and effective treatment option for addressing speech issues in adult patients with VPI.

Evaluation of Quantitative Aspects of Craniofacial Deformities in Transfusion Dependent Beta-Thalassemia Major Patients: A Cephalometric Study.

PURPOSE: To evaluate the quantitative (cephalometric) aspects of the craniofacial deformities in transfusion-dependent beta-thalassemia (TDT) patients. MATERIALS AND METHODS: Sixty-five TDT patients receiving a regular blood transfusion in the Department of Pediatrics of age group 5 to 8 years (younger) and 15 years and above (older) were compared with control groups of similar age using cephalograms (lateral and posterior-anterior view). RESULTS AND OBSERVATION: The prevalence of skeletal class II tendency is higher in thalassemic patients that do not improve with age. The thalassemic patients were found to show large angle ANB i.e. Angle between points point a, nasion and point B (ANB), large flexure angle, small angle SNB i.e. Angle between points sella, nasion and point B (SNB), and normal angle SNA i.e. Angle between points sella, nasion and point A (SNA) angles suggestive of retrognathic mandible. The thalassemic patients were observed to have smaller transverse widths and thickened calvarium on the posterior-anterior view. CONCLUSION: The skeletal class II malocclusion appears to be a manifestation of generalized growth retardation/delayed puberty in thalassemic patients leading to diminished mandibular growth, rather than maxillary prognathism due to marrow hyperplasia.

Comparative Assessment of Autogenous Cancellous Bone Graft and Bovine-Derived Demineralized Bone Matrix for Secondary Alveolar Bone Grafting in Patients With Unilateral Cleft Lip and Palate.

OBJECTIVE: Comparison between bovine-derived demineralized bone matrix (DMBM) and iliac crest graft over long term for secondary alveolar bone grafting (SABG) in patients with unilateral cleft lip and palate (UCLP) in terms of radiological and clinical outcomes. DESIGN: Prospective, randomized, parallel groups, double-blind, controlled trial. SETTING: Unit of Oral and Maxillofacial Surgery, Oral Health Science Centre, Postgraduate Institute of Medical Education & Research, Chandigarh. PARTICIPANTS: Twenty patients with UCLP. INTERVENTIONS: Patients were allocated into group I (Iliac crest bone graft) and group II (DMBM) for SABG. Outcomes were assessed at 2 weeks, 6 months, and then after mean follow-up period of 63 months. OUTCOMES MEASURES: Volumetric analysis of the grafted bone in the alveolar cleft site was done through cone beam computed tomography using Cavalieri principle and modified assessment tool. Clinical assessment was performed in terms of pain, swelling, duration of hospital stay, cost of surgery, alar base symmetry, and donor site morbidity associated with iliac crest harvesting. RESULTS: Volumetric analysis through Cavalieri principle revealed comparable bone uptake at follow-up of 6 months between group I (70%) and group II (69%). Modified assessment tool showed no significant difference between horizontal and vertical bone scores over short- and long-term follow-up. In group II, there was higher cost of surgery, but no donor site morbidity unlike group I. CONCLUSIONS: Demineralized bone matrix proved analogous to iliac crest bone graft as per volumetric analysis over shorter period. However, although statistically insignificant, net bone volume achieved was lower than the iliac crest graft at longer follow-up.

Nasalance Scores as a Function of Skeletal Malocclusion of English-Speaking Adults in the North Indian Population.

OBJECTIVE: The objective of this study is quantitative assessment of nasalance for skeletal Class I (normative values), Class II, and III malocclusion in the English language for the North Indian population and to compare the normative values with the nasalance scores obtained from individuals with skeletal Class II and III malocclusion and to evaluate the normative values as a function of gender. MATERIAL AND METHODS: The study was conducted on a total sample of 200 patients with 100, 50, and 50 in group 1 (control group, Skeletal Class I), group 2 (Skeletal Class II), and group 3 (Skeletal Class III), respectively. ANB angle (anteroposterior angle formed by point A, nasion, and point B) measured on lateral cephalogram was used to categorize the patients into 3 groups. The normative nasalance scores were compared for males and females in the control group. The nasalance scores of skeletal Class II and III subjects were compared to the combined normative scores of the control group. The NasalView was used for the objective assessment of nasalance. Oral syllables (/pa/and/pi/), nasal syllables (/ma/and/mi/), and 3 passages (Zoo passage, Rainbow passage, and Nasal sentences) were used to determine the nasalance scores. RESULTS: The intragroup comparison of nasalance scores in group 1 showed statistically significant differences for different stimuli. The gender-related comparison showed no statistically significant differences in nasalance scores. The intergroup comparison of nasalance scores for skeletal malocclusion showed no statistically significant differences for different stimuli except statistically significant lower nasalance values for nasal sentences in group 3 compared to the control group. CONCLUSION: The study concluded that the nasalance scores for nasal sentences in skeletal Class III malocclusion were significantly lower than in the control group and were not statistically significant between the 3 groups for all other stimuli.

Inter-estuarine and seasonal to decadal variations of heavy metal pollution in the Gulf of Cambay, India.

Toxic heavy metals adsorbed preferentially onto suspended sediments enter our food chain by bio-assimilation in coastal ocean organisms. To decipher metal pollution status in the Gulf of Cambay (food hub of India) under rising anthropogenic pressure, we present seasonal abundances of Ti, Cr, Co, Ni, Cu, Zn, Cd, and Pb in > 150 samples of suspended sediments (> 0.45 µm) collected in four seasons (2016-2017) from two large estuaries (Narmada and Tapi). The suspended sediments of both the estuaries generally show low heavy metal pollution (Igeo < 1). The hotspots of moderate-to-high pollution of Pb (Igeo < 4), Cd (Igeo < 3), and Zn (Igeo < 2) are found at salinity < 2, and those of Co (Igeo < 2) at salinity ~ 20-30 in the Tapi estuary during the non-monsoon seasons indicating their decoupled sources in Surat. The PLI values show no or little seasonality in the overall metal pollution status of both the estuaries. A comparison with the literature data suggests that suspended sediments efficiently capture active metal pollution in Indian estuaries. Furthermore, a recent decline (2004-2017) in estuarine metal pollution in the Gulf of Cambay found in this study could be due to enhanced organic matter supplies by enhanced urban sewage discharge and/or more trapping of contaminated riverine sediments upstream of the newly built large dam reservoirs counteracting the growth of anthropogenic metal inputs in the Narmada and Tapi watersheds. The data scarcity of heavy metal concentrations in suspended sediments limits reporting unambiguously the current pollution status of other major Indian estuaries.

Primary Intrathoracic Sarcomas: A Review of Cross-sectional Imaging and Pathology.

The most common sarcomas in the thorax are metastasis from an extrathoracic primary malignancy. Primary intrathoracic sarcomas are rare albeit aggressive malignancies that are diagnosed on histopathology. Although a few imaging characteristics have been described that are common to sarcomas, it is still a diagnosis of exclusion as other tumors are much more common. Like elsewhere, primary thoracic sarcomas are also classified according to their histologic features. They are a rare group of tumors that can arise from the mediastinal structures, lung, pleura, or chest wall. On imaging, differentiating these from more common malignancies like lung cancer is difficult and often requires multimodality workup and tissue sampling. A few sarcomas are very specific to their locations, such as angiosarcoma in the right atrium, leiomyosarcoma in the pulmonary artery, where imaging has high accuracy for the diagnosis. Despite being nonspecific in a majority of cases, imaging plays a pivotal role in determining the organ of origin, tumor extent, invasion of adjacent structures, and thus help to assess the surgical resectability. Although sarcomas arising from chest wall are the most common primary sarcomas in the chest, they are excluded from this review to focus only on primary intrathoracic sarcomas. The article provides a comprehensive imaging and pathology review of the rare primary intrathoracic sarcomas, including but not limited to angiosarcoma, Kaposi sarcoma, fibrosarcoma, malignant transformation of fibrous tumor of pleura, sarcomatoid mesothelioma, leiomyosarcoma, and malignant small round blue cell tumors.Key points:Primary intrathoracic sarcomas are rare but clinically important.Imaging helps to determine local extent, invasion, metastases and appropriate site/mode of biopsy.Role of pathology is paramount in diagnosis and guiding treatment based on immunogenetic/molecular typing.

Maxillary distraction osteogenesis at Le Fort-I level induces bone apposition at infraorbital rim.

OBJECTIVE: The aim of this study is to evaluate whether there is any remodeling of bone at infraorbital rim following maxillary distraction osteogenesis (DO) at Le Fort-I level. MATERIALS AND METHODS: Twelve adult subjects in the age range of 17-21 years with complete unilateral cleft lip and palate underwent advancement of the maxilla by DO. The effect of maxillary DO on the infraorbital rim remodeling was evaluated from lateral cephalograms recorded prior to the DO (T0), at the end of DO (T1), and at least 2-years after the DO (T2) by Walker's analysis. The ANOVA and two-tailed t test were used and probability value (P value) 0.05 was considered as statistically significant level. RESULTS: There was anterior movement of maxilla by 9.22 ± 3.27 mm and 7.67 ± 3.99 mm at the end of immediate (T1) and long-term (T2) follow-up of maxillary DO, respectively. The Walker's analysis showed 1.49 ± 1.22 mm and 2.31 ± 1.81 mm anterior movement of the infraorbital margin (Orbitale point) at the end of T1 and T2, respectively (P < 0.01). This apposition of bone at the infraorbital rim region further improved the facial profile of these patients. CONCLUSION: The advancement of maxilla by distraction osteogenesis at Le Fort-I level induced significant bone apposition at infraorbital rim. CLINICAL RELEVANCE: Patients with mild midface hypoplasia who would otherwise may be candidates for osteotomy at Le Fort-II or Le Fort-III level may benefit from maxillary distraction at Le Fort-I level.

Increase in sagittal depth of the bony nasopharynx following maxillary protraction in patients with unilateral cleft lip and palate.

Objective : To study the change in the sagittal depth of the bony nasopharynx in patients with unilateral cleft lip and palate (UCLP), following maxillary protraction using reverse headgear. Methods : Nineteen patients (14 male, five female; aged 9.36 ± 2.89 years) with repaired complete UCLP underwent maxillary protraction with a Delaire type reverse headgear at a tertiary-care referral teaching hospital. Control data were taken from five patients (four male, one female; aged 8.25 ± 2.25 years) who did not receive any orthopedic/orthodontic treatment for a similar duration of time as the treated patients. Average treatment/observation period was 11.71 ± 3.39 months for the treated patients and 12.40 ± 2.60 months for the untreated subjects. Changes in the sagittal bony nasopharynx depth were measured by comparing pretreatment (T1) and posttreatment (T2) lateral cephalograms. Correlations between the changes in the bony nasopharynx depth and in other variables measured in the treated patients were analyzed. An exploratory analysis of differences in the changes from T1 to T2 between the treated patients and untreated subjects was also conducted. Results : The favorable skeletal changes seen in SNA and ANB following maxillary protraction were accompanied by a significant increase in the sagittal depth of bony nasopharynx (1.74 ± 1.10 mm; P < .001). This change was significant when compared with the data from the untreated subjects (P = .004). Correlations between the increase in bony nasopharynx depth and changes in other variables studied in the treated patients were weak and not statistically significant. Conclusion : Sagittal depth of the bony nasopharynx in patients with repaired UCLP increased following maxillary protraction therapy using reverse headgear.

To Study the Outcome of Cartilage Tympanoplasty Type I in Patients with Medium and Large Perforations Using 0.5 mm Sliced Conchal Cartilage Reinforced with Temporalis Fascia Grafts with 5 Years Follow-up.

Aims: To study the outcome of cartilage tympanoplasty type I in patients with medium and large perforations using 0.5 mm sliced conchal cartilage reinforced with temporalis fascia grafts with 5 years follow-up. Study Design: Retrospective clinical study. Patients and Method: 120 patients with dry tympanic membrane perforation medium and large size and intact ossicular chain, and with no history of previous ear surgery were selected. An underlay type one tympanoplasty, using 0.5 mm sliced conchal cartilage reinforced with temporalis fascia, was performed during 2018-19. A successful anatomical outcome was considered to comprise full, intact healing of the graft without perforation these patients were evaluated for at least 5 years post-operatively till 2023. Results: In this study graft uptake rate was 95.33% for medium size and 93.66% for large perforations at 3 months and after 5 years of follow-up 92.77% medium size and large size perforations were 89.67.66% (P < 0.001). Residual perforations were there in about 7.29% in medium and 10.33% in large size perfrations. Conclusion: Sliced conchal cartilage reinforced with temporalis fascia is a reliable technique for tympanoplasty, with improved graft uptake results in medium and large perforations in the long-term, also the residual perforations is significantly lower.

The Lingering Effects of COVID-19: The Psychological State and Quality of Life of Patients with Persistent Loss of Smell and Taste.

The COVID-19 pandemic has resulted in a significant number of individuals experiencing the loss of smell and taste, medically known as anosmia and ageusia, respectively. While many patients recover these senses during the post-acute phase of the illness, a subset of individuals continues to suffer from anosmia and ageusia even after recovering from COVID-19. This article aims to explore the psychological state of COVID patients who have not regained their sense of smell and taste post-recovery, highlighting the potential impact on their mental health and overall well-being. To accomplish this, a comprehensive review of existing literature on the topic has been conducted, analyzing studies and reports that shed light on the psychological consequences of unrecovered anosmia and ageusia in COVID patients.

"The impact of orthognathic surgery on articulation proficiency and speech intelligibility in skeletal Class III malocclusion: 18 months follow up".

Introduction: Orthognathic surgery results in the positional change of the maxilla and mandible that may affect speech. The present study evaluated the effect of combined maxillary advancement and mandibular setback surgery on articulation proficiency and speech intelligibility in patients with non-syndromic skeletal Class III malocclusion. Methods: In this prospective study, twenty-five patients with skeletal class III malocclusion and consecutively treated with Lefort-1 maxillary advancement and mandibular setback (BSSO) orthognathic surgery were included in this study. The speech sample was recorded with a digital audio tape recorder one day before surgery and at 3, 6, 9, 12 and 18 months after surgery. Three qualified and experienced speech and language pathologists evaluated articulation errors and intelligibility of speech samples. Repeated One-way analysis of variance was used to compare articulation proficiency and speech intelligibility at different time intervals. Results: The substitution, omission, distortion and addition errors showed no significant changes at 3 months and 6 months. The total articulation errors decreased to zero at 9 months and no significant increase was observed till 18 months (P < 0.05). Speech intelligibility showed statistically non-significant improvement at any time interval. Cephalometric skeletal parameters SNA and N l A°. were significantly correlated with addition and total articulation errors at 18 months follow up. Conclusions: The ortho-surgical treatment improves speech (decreases. articulation errors) in most of the patients usually 6-9 months post-surgery. Speech intelligibility is not affected by bimaxillary orthognathic surgery in skeletal class III patients. The articulation errors were correlated to changes in position of maxilla.

Isotopic evidence of autochthonous organic matter acting as a major sink of anthropogenic heavy metals in modern lacustrine sediments.

The knowledge of major sources, sinks, and the burial fate of various pollutants added to modern aquatic ecosystems under changing environmental conditions is limited but crucial for our sustainability. In this context, the spatial distributions and causative factors of organic matter (OM) and heavy metal accumulations have been explored in modern lacustrine sediments of a large urbanized and protected wetland (ULB: Upper Lake Bhopal) in Central India. For this purpose, geochemical properties, in particular, stable isotopes (δ13C and δ15N) were measured in the ULB surficial sediments (core depth ∼0-1 cm; n = 19), and additionally collected riverbed sediments (n = 2) and atmospheric free-fall dust samples (n = 3) from the lake periphery. The major and trace element data indicate widespread mafic sediment provenance and nearly dysoxic lacustrine conditions. The riverine supply of soil OM from cropped lands and the lake productivity (algae, largely sustained by nutrients from sewage and agricultural runoff) are the major OM sources to the western and eastern lake portions, respectively. The fractional contribution from autochthonous TOC (∼0.19-0.95, mean ∼0.62) predominates that of allochthonous TOC (∼0.05-0.81, mean ∼0.38). Whereas, atmospheric dust deposition is a primary anthropogenic source of heavy metals (Pb and Zn). The lake productivity rather than soil OM or any mineral sorbent is found responsible for the anthropogenic enrichments of Pb and Zn in the ULB surficial sediments, especially on the eastern ULB portion under high anthropogenic pressure. Therefore, the settled OM (primarily autochthonous) being oxidizable acts as a temporary but major sink of anthropogenic heavy metals in modern lacustrine sediments, which are vulnerable to heavy metal efflux to the water column by sediment diagenesis.

Orthodontic emergencies and mental health of patients undergoing orthodontic treatment during COVID-19 pandemic: A questionnaire study.

Objectives: To evaluate the impact of COVID-19 pandemic on orthodontic treatment and mental health of patients undergoing orthodontic treatment and to compare their mental health with the age-matched control group. Materials and methods: 484 orthodontic patients (245 males and 239 females) and 200 age-matched control subjects were divided into two age groups. Group 1 had 14-18 years of adolescents (N = 274) and 100 control participants (Group 2) and Group 3 comprised of 19 years above adults (N = 210) and 100 control participants (Group 4). Group 1 and 3 patients filled the 4 sections of the questionnaire related to orthodontic emergencies (Sections 1-3) and mental distress (Kessler Psychological Distress Scale-Section 4), while groups 2 and 4 were asked to fill only Section-4. The comparison of mental distress on high/low Kessler scores was made using the Chi-Square test/Fisher's exact test. The factors which came out to be significant were put to bivariate logistic regression analysis. Results: The percentage of patients with high Kessler scores among Group 1 and Group 3 were 9.9% and 17.2% respectively, and their differences with age-matched control groups were non-significant. The mean differences of Kessler score were significantly higher for Group 3 compared to group 1. The higher Kessler score was associated with age, higher education, a feeling of concern for non-availability of appointments, increased treatment duration, its effect on the quality of treatment, and sabotaging of definitive future plans. Conclusions: The orthodontic treatment and emergencies may not be a significant factor contributing to increased stress among patients during the lockdown.

Success rate, treatment duration, and pain perception in the management of palatally impacted canines using the K9 and Ballista spring: a randomized clinical trial.

OBJECTIVES: To evaluate the success rate, treatment duration, and pain perceived during forced eruption of maxillary palatally impacted canines using the K9 and Ballista springs. MATERIALS AND METHODS: Thirty unilateral palatal canine impactions of moderate and difficult category as determined by KPG index (score between 10 and 19) were enrolled. Group 1 comprised canine impactions managed with K9 springs, and Group 2 comprised Ballista springs. Block randomization and opaque sealed envelopes were used for allocation. The success rate and treatment duration (application of force to ligation of the impacted canine into the initial alignment archwire) were recorded. Pain perception was evaluated on a 10-point visual analogue scale (VAS) and modified McGill Pain Questionnaire. Chi-square test and Mann-Whitney U-test were used to compare the groups. RESULTS: The success rate for eruption of palatally impacted canines was 100%. The average treatment duration was 296.13 ± 96.45 days and 311.93 ± 94.34 days, respectively for Group 1 and Group 2. VAS scale scores for pain were greater for Group 2 compared to Group1, and the differences were statistically significant at all time intervals except at T1. The frequency of none and mild pain was significantly greater at all time intervals in both groups. CONCLUSIONS: The impacted canines of moderate and difficult category were erupted with a 100% success rate and similar treatment duration with both interventions. The pain scores of Ballista springs were greater after 24 hours of force application.

Assessment of Self-Esteem and Quality of Life in Patients with Complete Unilateral Cleft Lip and Palate Undergoing Orthodontic Treatment.

Objective: To assess the self-esteem and quality of life (QOL) in patients with complete unilateral cleft lip and palate (UCLP) who were undergoing orthodontic treatment. Materials and Methods: This cross-sectional study was conducted on a total sample of 300 individuals consisted of 150 patients with UCLP (Group I) and 150 normal controls (Group II) with an age range of 10-25 years, who were undergoing comprehensive orthodontic treatment from December 2016 to December 2018. The Self Esteem and QOL were assessed using the Rosenberg Self Esteem scale (RSE) and Modified Paediatric QOL Inventory Scale (M-PQOL), respectively, in Group I and II. Results: The comparison of overall mean scores of responses to RSE questionnaires showed nonsignificant differences for all the responses and was significant only for RSE 6 and RSE 8 in the age group of 10-15 years and 21-25 years, respectively, and nonsignificant for all other questions in all the age groups. The comparison of overall mean scores of M-PQOL for the total sample showed nonsignificant differences in Group I and II for physical functioning, emotional functioning, and school functioning domain, and were highly significant differences (P ≤ 0.001) in the social functioning domain and M-PQOL 12 and M-PQOL 21. Conclusions: This study demands a definite need of a psychologist/psychiatrist among the cleft care team to counsel the patients with cleft during orthodontic treatment for motivating them to gain self-respect and acceptance in the society as certain aspects, particularly social functioning domain made them feel different from normal children because of the functional and aesthetic problems.
