To Study the Effectiveness of Inhalation Technique Training in Patients with COPD and Asthma.

INTRODUCTION: Asthma and chronic obstructive pulmonary disease (COPD) are characterized by chronic airway inflammation. Lack of knowledge about the correct inhalation techniques leads to poor control of both diseases. This study aimed to study the effectiveness of inhalation technique training in patients with COPD and asthma. MATERIALS AND METHODS: A total of 132 patients fulfilling the inclusion criteria were trained with the correct technique of inhalation on day 0 and at the end of 1 and 6 months. Evaluation of technique training was done on these three occasions posttraining. The mean score of devices was obtained, and the mean inhalation technique score of various devices was compared. RESULTS: Out of 132 patients, 65.1% (86/132) patients were using a dry powdered inhaler (DPIs), 26.5% (35/132) patients used metered dose inhalers (MDIs), and 8.4% (11/132) patients used MDI with spacer. The mean scores of patients using MDI at baseline were 5.68 ± 0.83, and after 1 month, 6.68 ± 0.58 (p < 0.000). The inhalation technique mean score of MDI improved after 6 months, 7.02 ± 0.56 as compared to baseline (p < 0.008) mean score of the patients using DPIs improved after 1 month, 5.53 ± 0.58 as compared to baseline 4.37 ± 5.53 (p < 0.000). There was no statistical improvement in the device mean score of DPIs after 6 months, 5.62 ± 0.55 when compared with 1 month, 5.53 ± 0.58 (p < 0.117). Patients who used pressurized metered-dose inhalers (pMDI) with spacers improved their inhalation score after 1 month by 6.90 ± 0.94 as compared to the baseline score of 6.90 ± 0.94 (p < 0.001). The mean score decreased marginally after 6 months, 7.818 ± 0.60, as compared to the score at the end of 1 month of 8.27 ± 0.64 (p < 0.053). DISCUSSION: Patients showed improvement in the technique of inhalation after educational training, reinstructions, and a standard checklist.

Study of Association of Chromosomal Region 1Q21-23 with Rheumatoid Arthritis and Their Correlation with Severity of Disease.

BACKGROUND: The understanding of the pathophysiology of rheumatoid arthritis (RA) has taken a major step forward with the research of new illness-related genes and further deciphering the involved molecular. Gene variants like human leukocyte antigen (HLA)-DRB1 and PTPN22 1858T act as individual risk factors for RA. It also serves as a risk factor for the rate of progression of joint destruction and clinical manifestations in autoimmune diseases like RA. The focus of this study is to find out the association of chromosomal region 1q21-23 with RA and its connection with disease severity using the disease activity score (DAS) and distribution frequency of the prevalent alleles of such genes in an already recruited group of patients/controls of India, specifically Northwest Rajasthan. MATERIALS AND METHODS: This was a case-control study wherein every patient of RA aged 16 years and above diagnosed with RA as per the 2010 American College of Rheumatology (ACR) and the European League against Rheumatism (EULAR) revised criteria for RA in Outpatient Department (OPD) and Inpatient Department (IPD) patients were included. Blood samples of the study population were drawn at Sardar Patel Medical College (SPMC), Bikaner (rheumatology OPD), along with the cooperation of Birla Institute of Technology and Science (BITS), Hyderabad (Department of Biological Sciences) from July 2009 to January 2012. A total of 100 controls (without any previous history of disease) and 135 cases were selected considering inclusion and exclusion criteria. Clinical data along with laboratory parameters like complete blood count, serum electrolytes (sodium, potassium, calcium, and chlorine ions), blood sugar, blood urea with serum creatinine, lactate dehydrogenase (LDH) isoenzymes assay, serum glutamic-oxaloacetic transaminase (SGOT)/serum glutamic pyruvic transaminase (SGPT) ratio, serum γ-glutamyl transferase (GGT) level, serum amylase, arterial blood gas (ABG), total serum proteins were evaluated and recorded from the patients. RESULTS: Our study showed control group has a mean age of 45.11 + 4.12 years. The case and control groups did not have significant differences in any of the clinical variables. 59% of cases show joint deformity. Allelic frequencies of the D1S498 polymorphism in cases were found significant in sizes 198, 204, 208, and 210, while it was found insignificant in sizes 192, 196, 200, 202, and 206. No correlation was found in allelic frequencies of the D1S318 polymorphism in cases and controls. CONCLUSION: Bigger cohort studies will allow better genomic elucidation of clinically defined intermediate phenotypes evaluated in RA patients by virtue of the autoimmune origin of the disease and its diverse symptoms in patients. Genetic-molecular studies can be a milestone for adopting effective personalized treatment for such progressively debilitating diseases. How to cite this article: Gauri LA, Meena MK, Singh U, et al.

Five Times Reactivation of COVID-19 in a Patient with Thymoma.

BACKGROUND: The possibility of recurrence in COVID-19 is very rare and hence mostly underdiagnosed. In the face of pandemic, this can lead to circulation of the virus like a hidden iceberg. Better understanding about this topic can improve our knowledge of the COVID-19 pathogenesis and ways to control the transmission. CASE PRESENTATION: A 41 year old male with no known comorbidities was admitted five times during a period of 7 months each time after being detected RTPCR positive for SARS-CoV-2 and more symptomatic than previously. He had no contact with other COVID-19 patients and was asymptomatic in between admissions. Despite this, he did not develop antibodies against SARSCoV-2. Later on, he was diagnosed with thymoma on biopsy of the anterior mediastinal mass. Patient's condition deteriorated on last hospitalization and he died, despite the treatment. Here we present an interesting report on multiple times recurrent COVID-19 infection, probably a case of reactivation and different plausible explanations on the role of thymoma.;Conclusion: Acknowledging the potential of SARS-CoV-2 to cause recurrence is very important during the pandemic as a part of the long term transmission mitigation. The case report shows that previous infection does not guarantee complete immunity from COVID-19, especially in immuno-compromised patients. Hence, despite the status of prior infection, vulnerable individuals who recovered from COVID-19 should be under surveillance.

Calprotectin and N-telopeptide of Type I Collagen (NTx) as Gingival Crevicular Fluid (GCF) Biomarker in Peri-Implantitis Patients.

INTRODUCTION: Formulation of various preventive and therapeutic strategies is possible only by a better understanding of the immune-inflammatory profile of peri-implant diseases. For understanding the changes and turnover of bone, various markers have been used in the past literature, out of which, N-telopeptide of Type I Collagen (NTx) is acknowledged to be the most reliable marker. AIMS AND OBJECTIVES: Assessment of calprotectin and NTx concentration in gingival crevicular fluid (GCF) around the implant sites in subjects suffering from peri-implantitis. MATERIALS AND METHODS: In total, 70 healthy individuals were included in the present study. These patients had opted for dental implants within the last decade. After collecting the peri-implant crevicular fluid (PICF) and GCF, various examinations were carried out. PICF samples were obtained with the help of sterile paper available in the form of strips. The enzyme-linked immunosorbent assay (ELISA) technique was used for measuring the calprotectin and NTx. All the readings were obtained in nanograms per microliter of PICF. All the results were recorded and analyzed. RESULTS: The overall mean calprotectin and NTx values were observed to be in a significantly higher range within the sites suffering from peri-implantitis when compared with healthy locations. The calprotectin values and NTx levels were positively correlated with the mean values of periodontal parameters observed clinically. CONCLUSION: Both calprotectin and NTx could be used as a biomarker signifying the presence of inflammation as well as bone resorption in patients suffering from peri-implantitis.

Efficacy of Transcutaneous Electric Nerve Stimulation (TENS) on Whole Salivary Flow Rate: A Descriptive Observational Study.

Statement of the Problem: Saliva is a precious oral fluid that contributes to oral health and when its quantity is diminished, it hampers the quality of life. Individuals suffering from diabetes have a complaint of reduced salivation due to the consumption of xerogenic drugs and autonomic neuropathy. Purpose: Our study aims to evaluate the effectiveness of the transcutaneous electric nerve stimulation (TENS) device on the salivary flow rate with respect to age and gender in Jaipur population. Materials and Method: A descriptive observational study was carried out on individuals in Jaipur at the Department of Oral Medicine and Radiology at Rajasthan Dental College and Hospital during a period of 7 months. The study consisted of 200 individuals who were divided into two groups. Unstimulated and stimulated saliva were collected for 5 minutes in a graduated beaker. Stimulated saliva was collected after keeping the TENS unit activated at 50Hz. Kolmogorov-Smirnov, Shapiro-Wilks normality tests and Mann Whitney U test were done. The p value <0.05 was considered to be significant. Results: The TENS unit was effective in increasing the quantity of stimulated saliva and a highly statistical significance was seen in age groups. TENS was also found to be more effective in increasing saliva in diabetic individuals. The mean unstimulated salivary rate was 1.64ml/5min and the mean stimulated salivary rate was 1.914ml/5min for Group I. The mean unstimulated salivary rate was 1.231ml/5 min and the mean stimulated salivary rate was 1.547ml/5 min for Group II. The p value for Group I and II for unstimulated saliva was 0.01 and for stimulated saliva was 0.03. Conclusion: It seems that TENS has shown positive results in increasing salivary secretions and salivary values may diminish with age; therefore, TENS might be used in aged individuals as well as in diabetic patients to increase the quantity of saliva.

Diagnosis and management options in malignant pleural effusions.

Malignant pleural effusion (MPE) denotes an advanced malignant disease process. Most of the MPE are metastatic involvement of the pleura from primary malignancy at lung, breast, and other body sites apart from lymphomas. The diagnosis of MPE has been traditionally made on cytological examination of pleural fluid and/or histological examination of pleural biopsy tissue that still remains the initial approach in these cases. There has been tremendous advancement in the diagnosis of MPE now a day with techniques i.e. characteristic Ultrasound and computed tomography features, image guided biopsies, fluorodeoxyglucose-positron emission tomography imaging, thoracoscopy with direct biopsy under vision, tumor marker studies and immunocytochemical analysis etc., that have made possible an early diagnosis of MPE. The management of MPE still remains a challenge to pulmonologist and oncologist. Despite having various modalities with better tolerance such as pleurodesis and indwelling pleural catheters etc., for long-term control, all the management approaches remain palliative to improve the quality of life and reduce symptoms. While choosing an appropriate management intervention, one should consider the clinical status of the patient, life expectancy, overall cost, availability and comparative institutional outcomes, etc.

Comparative study of clinico-bacterio-radiological profile and treatment outcome of smokers and nonsmokers suffering from pulmonary tuberculosis.

INTRODUCTION: Tuberculosis (TB) is one of the leading causes of death and disease worldwide. Tobacco smoking has been linked as a risk factor for TB. This study was aimed to affirm the strength of association between smoking and pulmonary TB. MATERIALS AND METHODS: Pulmonary TB patients aged between 18 and 65 years were enrolled and followed-up until treatment completion. Two consecutive sputum smears were examined from each patient for the presence of acid-fast bacilli (AFB) using Ziehl-Neelsen technique. Radiological severity of disease was assessed using guidelines of National TB Association of USA. Sputum smears for AFB were graded for positivity as per WHO Revised National TB Control Programme criteria. Response was determined in terms of sputum conversion at the end of intensive phase and final treatment outcomes. RESULTS: Sputum smear grading of 3+ increased from 12.5% to 68.18% and 66.66% as smoking index increased from <100 to 100-299 and >300 (P < 0.05). In nonsmokers, 79.2% patients had minimal disease while only 4.2% had advanced disease as compared to smokers where 52.4% had moderate disease, 26.2% advanced disease, and 21.4% minimal disease (P < 0.01). Smokers had significantly lower treatment success rate (69%) as against nonsmokers and former smokers (93.8% and 90.9%, respectively, P = 0.001) owing to a higher default rate among smokers (28.5%) than nonsmokers (6.3%) and former smokers (9.1%). CONCLUSION: Smokers during initial presentation, as well as at end of the treatment demonstrate more radiological findings, cavitary disease, and worse sputum AFB smear grading. Smokers also have a poorer treatment success rate largely due to high percentage of default rate thus suggesting noncompliance as a main confounder to treatment success. Focus needs to be made to reduce defaulters which are more common among smokers.

Pneumomediastinum, bilateral pneumothorax and subcutaneous emphysema complicating acute silicosis.

A case of acute silicosis complicating as spontaneous pneumomediastinum, bilateral pneumothorax and subcutaneous emphysema is described in a 35-year-old male engaged in stone crusher unit. Diagnosis was established on clinical and radiological assessment and supported by occupational history of the patient. This case is unique one as all these 3 complications at the same time are very uncommon in acute silicosis.

Hepatic abscess as a paradoxical response to antituberculous chemotherapy for tubercular lymphadenitis.

Tubercular liver abscess developing as a paradoxical reaction (PR) to antitubercular therapy (ATT) is relatively uncommon in the absence of disseminated disease and immunocompromised status of the host even in countries such as India where the disease is rampant. We report a rare case of hepatic abscess that developed paradoxically during antituberculous therapy for tubercular lymphadenitis in a 30-year-old woman who tested negative for HIV. Diagnosis was performed with the help of ultrasonography (USG)-guided aspiration of the abscess followed by cytopathological examination and PCR confirmation of the disease from the USG-guided aspirate. The patient responded well to oral corticosteroid therapy without any alteration of the ongoing ATT regimen. Details of the case and other relevant literature regarding the pathogenesis of this event are discussed in detail.

Myxosarcoma of the maxilla - a case report.

Myxosarcoma is a rare malignant neoplasm of connective tissue which is characterized by tissue that resembles primitive mesenchyme, and contains relatively undifferentiated cells that show rapid growth and invasion. The cells are stellate or spindle-shaped and are present in a loose matrix which contains mucoid material, reticulum, and collagen fibers. This paper reports a rare case of a myxosarcoma of the left maxilla in a 50-year-old male, which clinically presented as a soft-tissue mass on the buccal gingiva and radiographically showed a mixed radiolucent-radiopaque appearance.

Fibrous Ankylosis of the Temporomandibular Joint in a Young Child.

Temporomandibular joint (TMJ) ankylosis is an intracapsular union of the disccondyle complex to the temporal articular surface that restricts mandibular movements, including fibrous adhesions or bony fusion between the condyle, disc, glenoid fossa, and articular eminence. The leading causes include trauma and infection. It can be a serious and disabling condition that leads to difficulties in mastication, swallowing, speaking, esthetics and oral hygiene. Disturbances of facial and mandibular growth and acute compromise of the airway invariably result in physical and psychological disability. Treatment should be initiated as soon as the condition is recognized, with the main objective of re-establishing joint function and harmonious jaw function. The purpose of this report is to describe a case of unilateral fibrous ankylosis of the right TMJ in a three-year-old girl.

Tuberculosis of the triceps muscle.

A tubercular swelling of the triceps muscle in a 25-year-old immunocompetent man is described in this report. He presented with hard, fixed swelling at the lower end of the triceps muscle. Confirmatory diagnosis was established by fine-needle aspiration cytology (FNAC) of the swelling with subsequent PCR for Mycobacterium tuberculosis of the FNAC specimen. The patient was completely cured with antitubercular therapy.

Primary/local hepatic tuberculosis without dissemination.

We present a rare case of primary hepatic tuberculosis in a 50-year-old man who presented with pain at the right hypochondrium. The diagnosis was established by fine-needle aspiration cytology (FNAC) of the primary hepatic lesions in both lobes of the liver, which was further supported by histopathological examination and tissue PCR for Mycobacterium tuberculosis in the FNAC specimens.

Unicystic Ameloblastoma Presenting as a Multilocular Radiolucency in the Anterior Mandible: A Case Report.

Ameloblastomas are tumors of odontogenic epithelial origin. The term unicystic ameloblastoma is used to describe cystic lesions with clinico-radiographic features resembling an odontogenic cyst, but histologically showing the presence of ameloblastomatous epithelium lining part of the cyst cavity. A large majority of lesions are found in the mandible, and usually cause a painless swelling of the jaws. They can be radiographically subdivided into 'dentigerous' and 'non-dentigerous' types. The unicystic ameloblastoma is believed to be less aggressive than a solid/multicystic ameloblastoma, and thus has a more favorable response to enucleation and curettage. This case report presents a case of unicystic ameloblastoma with a multilocular radiographic appearance in the anterior mandible of a 45-year-old female patient, along with a literature review of the topic.

A rare case of pulmonary cysticercosis manifesting as lung cavity with pleural effusion.

Isolated pulmonary cysticercosis is extremely rare manifestation of a rather common disease which is distributed worldwide. Most common sites which provide perfect nourishment for the growth of cysticercosis are muscle and brain followed by eye. Pulmonary involvement in cysticercosis is very rare and if at all present, then ill-defined nodular shadows distributed throughout the lung is the usual radiological presentation. No case of cysticercosis presenting as lung cavity with pleural effusion has been reported so far in literature. We came across a rarest presentation of cysticercosis as cavity in the lung with effusion. After nullifying all the differential diagnosis of cavitary lung lesions, a diagnosis of pulmonary cysticercosis was made by histopathological examination of the lung cavity aspirate and enzyme linked immunosorbent assay (ELISA) for cysticercosis. Case was successfully treated with albendazole (15mg/kg) with steroid cover.

Surgical and bronchoscopic lung volume reduction in chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) is the most extensively studied and researched disease in pulmonology and a cause of significant morbidity, mortality, and financial burden on patient's family and country's economy. Its management continues to be a challenge to both the physician and the patient's family. So far, it is preventable and treatable but not curable. Emphysema, a phenotype of COPD, is the most debilitating condition associated with progressive exercise intolerance and severe dyspnea. Despite decades of research, medical treatments available so far have helped improve quality of life and slowed down the decline in respiratory function but did not significantly improve the survival benefits. Though surgical lung volume reduction (LVR) procedures have shown some promise in context to functional gains and survival but, only in a carefully selected group of patients, bronchoscopic LVR procedures are yet to explore their full potential and limitations. This paper retrospectively studied the developments so far, medical and surgical, with special emphasis on the bronchoscopic procedures of lung volume reduction, and tried to comparatively analyze the risks and benefits of each one of them through various trials and studies done to date.

Acute silicosis with bilateral pneumothorax.

We present a case of acute silicosis with bilateral pneumothorax of a 28-year-old man working at a stone crusher factory for 1 year. He presented to the emergency department with cough, respiratory distress and diffuse chest pain. The patient was managed with bilateral intercostal tube drainage under water seal, oxygen inhalation and conservative therapy. On follow-up he showed improvement of resting dyspnoea and was doing well. This case is being reported because of the rare complications of acute silicosis as bilateral pneumothorax.

Ameloblastoma: A clinicoradiographic and histopathologic correlation of 11 cases seen in Goa during 2008-2012.

OBJECTIVES: The purpose of this case series was to compare the clinical, radiographic, and histopathologic features of 11 cases of ameloblastoma that reported to the Goa Dental College and Hospital over a period of 4 years from January 2008 to December 2012. STUDY DESIGN: Data with respect to the patients' ages, sex, location of lesions, radiographic features, histopathologic features and surgical treatment and follow-up, was analyzed. RESULTS: The mean age in males was 23.25 ± 6.99 years, while that in females was 43.43 ± 17.13 years. Seven (63.63%) of the 11 subjects were females, and four (36.36%) were males. 10 (90.9%) of the 11 ameloblastomas were located in the mandible. Swelling was noted in all 11 patients. 10 cases showed radiographic findings, while one case was a peripheral soft-tissue variant. Seven (70%) of the 10 tumors were multilocular with a well-demarcated corticated border, and three cases (30%) were unilocular. Two cases showed a soap-bubble appearance. Histologically, five cases were unicystic, four were multicystic, one was desmoplastic and one was a peripheral variant. Follow-up ranged from 12 to 34 months and there were no signs of recurrence in any of the patients. CONCLUSIONS: Ameloblastomas more commonly occur in females at an older age, as compared with males. Radiographic features that could help in diagnosing ameloblastomas include its predominant occurrence in the mandible, multilocular radiolucency with well-defined, corticated, scalloped margins, expansion of buccal and lingual cortical plates, root resorption and tooth displacement.

Prevalence of malocclusion and orthodontic treatment needs among 12-15-year-old schoolchildren of fishermen of Kutch coast, Gujarat, India.

BACKGROUND: Malocclusion is one of the most common dental problems in mankind. Planning orthodontic treatment as well as an interceptive approach within a public health system requires information on the prevalence of malocclusions. AIM: The aim of the study was to assess the prevalence of malocclusion and orthodontic treatment needs among 12-15-year-old school children of fishermen of Kutch coast, Gujarat, India. MATERIALS AND METHODS: A cross-sectional descriptive survey was conducted among 947 school children offishermen of Kutch coast, Gujarat, India aged 12-15 years. The prevalence of malocclusion and orthodontic treatment needs was assessed using Dental Aesthetic Index. General information on demographic data was also recorded. A c2 test, analysis of variance (ANOVA) and Sheffe's test were employed for statistical analysis. RESULTS: Malocclusion and orthodontic treatment need was reported among 33.4% of the participants. Younger age group and female gender had significantly greater treatment need. Males and older age groups had significantly lesser prevalence of anterior crowding and largest anterior maxillary irregularity. CONCLUSIONS: Orthodontic treatment need among 33.4% calls for developing school based oral health promotion programmes for children with an inculcation of orthodontic treatment and educational programmes for parents (fishermen) addressing prevention and early interceptive treatment of malocclusion.
