A Study of Comparison of Outcomes of Submucous Diathermy, Coblation and Micro-debrider Assisted Inferior Turbinoplasty in Patients Having Inferior Turbinate Hypertrophy.

The cause of nasal obstruction in most of the patients is either nasal septal deviation or turbinate hypertrophy owing to vasomotor or perennial allergic rhinitis. Most cases of hypertrophic turbinate are usually mild and respond to antihistamine therapy, local decongestions, or allergy desensitization; however, surgery is required in some cases. In our present study, three surgical methods were used for inferior turbinoplasty i.e. Sub-mucous Diathermy, Coblation and Micro-debrider and patients were divided randomly in these groups. The efficacy and outcomes of these methods was compared on the basis of subjective and objective relief of symptoms and their safety, recurrence and post-operative morbidity. Out of 45 patients, highest number of patients belonged to 20-40 years of age with the mean age of 28.7 years and male female ration 0.78:1. All the patients were evaluated on the basis of preoperative Endoscopic grading of inferior turbinate and SNOT22 symptom scores (Sino Nasal Outcome Test 22), intra-operative timing and bleeding and post-operative pain, crusting, SNOT22 scores (Sino Nasal Outcome Test 22) and Endoscopic grading improvement in inferior turbinate. On comparing all the above methods, we found that Coblation and Micro- debrider were more or less equally effective and better than Sub-mucous diathermy for inferior turbinoplasty. Submucous diathermy has least benefits, still most commonly used method because of its simplicity, conventionality and least cost factor while other two methods need capital investment and higher learning curve of the surgeon.

Update on the Pathology of Pediatric Liver Tumors: A Pictorial Review.

Liver tumors in children are uncommon and show remarkable morphologic heterogeneity. Pediatric tumors may arise from either the epithelial or mesenchymal component of the liver and rarely may also show both lines of differentiation. Both benign and malignant liver tumors have been reported in children. The most common pediatric liver tumors by age are benign hepatic infantile hemangiomas in neonates and infants, malignant hepatoblastoma in infants and toddlers, and malignant hepatocellular carcinoma in teenagers. Here, we provide an up-to-date review of pediatric liver tumors. We discuss the clinical presentation, imaging findings, pathology, and relevant molecular features that can help in the correct identification of these tumors, which is important in managing these children.

Regenerative Therapy for the Permanent Immature Teeth: A Long Term Study. An Original Research.

Introduction: Endodontics faces several clinical difficulties while treating young necrotic permanent teeth. The use of regenerative endodontic procedures (REPs) enables apical closure, improved canal wall thickness, and root growth. The objective of this study was to assess the effects of these regenerative procedures on immature necrotic permanent teeth. Methods: This prospective clinical study was conducted at the tertiary care hospital for the study period of 2 years. This study includes 30 necrotic permanent immature teeth that were studied in 30 subjects of both genders. A standard REP protocol was used to treat every tooth. A follow-up visit was scheduled for each patient at timely intervals. Various study parameters as well as the demographics were assessed at each visit. To examine various parameters, a calibrated endodontist also performed a radiographic evaluation. Results: Our findings point to excellent rates of survival, clinical success, and apical pathological resolution for 29 teeth. After 2 years, there were significant variations in the root thickness area and the average root length. The apical diameter significantly decreased during the research period, with 30.8% of the instances exhibiting full apical closure. Apical diameter, root length, and thickness changed more frequently in teeth with the level of the immaturity of the root, although the variations were not significant. Conclusions: REP treatment for teeth preceded symptom relief. Increased root thickness, root length, and apical closure were seen at 30 months, even if the clinically meaningful change was not attained in all patients.

Electrophysiological Study in the Right Upper and Lower Limbs in Infants with Lumbosacral Meningomyelocele and in Normal Infants: A Case-control Study.

Objective: The study aimed to assess the electrophysiological parameters (Hofmann reflex [H-reflex] and motor nerve conduction velocity [MNCV]) on children's upper and lower limbs with lumbosacral meningomyelocele (MMC) and age-matched control to see the effect of the MMC on the cervical segment of the spinal cord. Materials and Methods: The present study was performed on infants with lumbosacral MMC. Twenty-five infants were examined with a mean age of 50 days of either sex. Out of them, 13 infants were in control and the remaining 12 were diagnosed with MMC. The H-reflex parameter and MNCV were recorded in these children's right upper and lower limbs. Results: H-reflex was elicited in all the control group babies. In MMC, the H-reflex was elicited in the upper limbs. However, H-reflex was not elicited in the lower limbs of a few MMC babies. The upper limb's H-reflex parameters and conduction velocity were significantly higher than those corresponding lower limbs in control babies. In MMC, where the H-reflex was elicited, such differences in the lower and upper limbs were not observed. However, the values of MNCV in the upper limb (right median nerve) were significantly less, and the values of Hmax in the lower limb (soleus muscle) were significantly more in MMC babies than in the control group. Conclusions: The values of electrophysiological parameters were higher in the upper limbs as compared to the corresponding lower limbs in control. These values were not altered in the upper limbs than those corresponding lower limbs of MMC, suggesting that motor function development was impaired/delayed in the spinal segment cranial to MMC lesion, and motor impairment in MMC children is mostly a result of upper motor neuron dysfunction.

Metastatic Renal Cell Carcinoma: An Enigmatic Nasal Mass.

Metastatic Renal Cell Carcinoma rarely presents in head and neck and is even rarer in the sinonasal region. However, a sinonasal metastatic mass is usually of RCC origin. These metastases may present prior to the renal symptoms or may appear after primary treatment. Report a 60-year lady with epistaxis due to metastatic RCC. Calculate total published cases of sino-nasal metastasis of RCC. Classify according to sequence of primary and metastatic presentation. A computer aided search of PubMed and Google scholar databases was done using pertinent combinations of the keywords "renal cell carcinoma", "nose and paranasal sinus", "metastasis", "delayed metastasis" and "unusual presentation", revealing 1350 articles. 38 relevant articles were included in the review. Our case presented with epistaxis 3 years after primary RCC. She had a vascular left sided nasal mass which was excised enblock. Immunohistochemistry confirmed metastatic RCC. She is on oral chemotherapy and asymptomatic 1 year post excision. Literature search revealed 116 such cases. 19 patients presented within 10 years of RCC while 7 more were delayed metastasis. 17 cases presented primarily with nasal symptoms with subsequent incidental renal mass. Chronology of presentation was unavailable in the rest 73 cases. We recommend to consider the diagnosis of sinonasal metastatic RCC in a patient presenting with epistaxis or nasal mass, particularly with a past history of RCC. Also, any person with known diagnosis of RCC should undergo regular ENT examination for early diagnosis of sinonasal metastasis.

Clinical and demographic comparison of celiac disease diagnosed during adulthood versus childhood and adolescence: A single-center experience.

Background and Aim: Celiac disease (CeD) is mainly reported from the northern and western parts of India. In central India, it is believed to be a disease of children, with limited data among adults diagnosed for the first time after the age of 18 years. Hence, we aimed to describe CeD's clinical and demographic features among adults and children/adolescents in central India. Methods: This is a retrospective analysis of a prospectively maintained database of all patients diagnosed for CeD from 2010 to 2019. The disease in adults was confirmed when symptoms developed for the first time after 18 years and had positive anti-transglutaminase antibodies with villous atrophy on duodenal biopsy. It was compared with pediatric patients with CeD diagnosed during the same time period. Results: Of the 170 patients diagnosed with CeD, 118 were adults and 52 were children or adolescents. The mean age of presentation of adult CeD was 37.3 ± 11.93 years, while in the pediatric and adolescent group it was 9.19 ± 5.4 years. Classical presentation with chronic, painless, small-bowel-type diarrhea was seen in 44.1% of adults compared to 57.7% in the pediatric age group. Among the adult patients, 55.9% presented with nonclassical symptoms, which included abdominal pain (40.7%) and weight loss (36.4%). The common presenting symptom in children other than diarrhea was weight loss (50%) and abdominal pain (34.6%). Conclusion: CeD is common in central India, with an increasing number of patients being diagnosed for the first time after 18 years of age and presenting more often with nonclassical symptoms.

Persistent Hyperglycemia Worsens the Oleic Acid Induced Acute Lung Injury in Rat Model of Type II Diabetes Mellitus.

Aim: This research aimed to study the impacts of persistent hyperglycemia on oleic acid (OA)-induced acute lung injury (ALI) in a rat model of type II diabetes mellitus. Materials and Methods: Healthy adult male albino rats that weigh 150 to 180 g were divided into four groups (n = 6). Group I-saline (75 µL i.v.) was injected and served as a control; group II-OA (75 µL i.v.) was injected to induce ALI. Group III-pretreated with a high-fat diet and streptozotocin (35 mg/kg), was injected with saline, and served as a control for group IV. Group IV was pretreated with a high-fat diet, and streptozotocin (35 mg/kg) was injected with OA (75 µL i.v). Urethane was used to anesthetize the animal. The jugular venous cannulation was done for drug/saline administration, carotid artery cannulation was done to record blood pressure, and the tracheal cannulation was done to maintain the respiratory tract's patent. Heart rate, mean arterial pressure, and respiratory frequency were recorded on a computerized chart recorder; an arterial blood sample was collected to measure PaO2/FiO2. Additionally, the pulmonary water content and lung histology were examined. Result: Hyperglycemic rats showed no significant change in the cardio-respiratory parameter. Histology of the lungs shows fibroblastic proliferation; however, rats survived throughout the observation period. There was an early deterioration of all the cardio-respiratory parameters in hyperglycemic rats when induced ALI (OA- induced), and survival time was significantly less compared to nonhyperglycemic rats. Conclusion: Persistent hyperglycemia may cause morphological changes in the lungs, which worsens the outcome of acute lung injury.

The Role of Antioxidant Agent (N-Acetylcysteine) in Oleic Acid-Induced Acute Lung Injury in a Rat Model.

Context Reactive oxygen species (ROS) produced by inflammatory cells play a major role in mediating lung injury in sepsis or hyperoxic lung injury. Aims N-Acetylcysteine (NAC), an antioxidant, was examined in this research to see whether it helps prevent acute lung injury (ALI). Materials and methods Experiments were performed on Charles-Foster strain healthy male adult albino rats. All the animals were randomly divided into one control and two experimental groups. In control/group I, saline was administered, and cardiorespiratory parameters were recorded. Oleic acid (OA) was administered in group II to produce ALI. In group III, OA was administered to NAC-pretreated rats, and cardiorespiratory parameters were recorded to observe the effect of NAC on ALI. This study used analysis of variance (ANOVA) with two factors and a post hoc test (multiple comparisons - least significant difference (LSD) test) for statical analysis. For determining survival time, the Mantel-Cox test and Kaplan-Meier survival curves were used. A P value < 0.05 was considered significant. Results Respiratory arrest, pulmonary edema, and reduced partial pressure of oxygen (PaO2)/fraction of inspired oxygen (FiO2) ratio were all indications of OA-induced ALI in rats. The animals in the NAC + OA group had better respiratory and cardiac statistics than those in the OA alone group, and their survival duration was extended. However, NAC pretreatment could not protect the animals against the development of pulmonary edema. Conclusions These observations indicate that NAC (an antioxidant agent) protected rats against ALI in the initial phase and prolonged the survival time but failed to prevent the development of pulmonary edema.

Assessment of Awareness Regarding Health Hazards of Plastic Chemicals and their Warning Label among a Sample Population of Varanasi City: A Cross-sectional Study.

BACKGROUND: Plastic containers are widely used to store and serve edibles. In the production of some types of plastic, chemicals such as bisphenol A (BPA) and bisphenol S (BPS) are used. These chemicals leach from the plastic containers into the edibles, get access into the biological systems, and cause a toxic impact on health. AIM: This cross-sectional survey was planned to assess the usage of food contact plastic and awareness regarding the health hazards of plastic chemicals and warning labels on plastic items among a sample population of Varanasi city. MATERIALS AND METHODS: Data were collected by interviewing the 556 adult participants, using a prevalidated structured questionnaire. Chi-square test was used to test the association and P < 0.05 was considered as significant. RESULTS: Most of the participants were found to be following routine practices during cooking and storage of edibles which may expose them to BPA and BPS through the gut. Although many participants were aware that plastic may contain some type of chemicals which may enter the human body and harm human health in some way, they lacked precise knowledge regarding warning label like "BPA free plastic" "plastic containing BPA" and "food grade plastic." Furthermore, none of the participants could recognize the "resin identification codes" correctly. CONCLUSION: Most of the participants had only elementary awareness of health risk of plastic usage. A significant number of participants lacked crucial information that can help them to make healthy choices as a consumer and use safe alternatives of plastic.

Development of a compact laser-diode based frequency domain photoacoustic sensing system: Application of human breast cancer diagnosis.

We present the development of a laser diode based photoacoustic spectral response (PASR) setup capable of diagnosing human breast cancer tissues through the use of mechanobiological properties of the tissue. A detailed description of the laser driver is provided, highlighting the important characteristics of the developed driver. Furthermore, the amplifier development is described. The developed laser diode based PASR system has been characterized using standard samples. Subsequently, the developed experiment has been applied onto diagnosis of human breast tumors. Energy has been used as a parameter to differentiate between normal and malignant tissues. The results were statistically consistent and then compared with standard histopathology for correlation.

Second Primary Cancer after Radiotherapy for Cervical Cancer.

Radiation is a treatment for many gynecological malignancies, especially locally advanced cervical cancer. Development of sarcoma due to previous radiation occurs very rarely. They develop within the radiation field. We report a case of carcinosarcoma in our patient developed 8 years after the radiotherapy (RT) that she received in the form of external beam radiation and intracavitary RT along with concomitant chemotherapy consisting of cisplatin. Although the development of secondary primary cancer is rare, for every patient who receives radiation for treatment of cancer, close follow-up is recommended as they may have viable endometrium.

Impact of SurePath® liquid-based preparation in cytological analysis of peritoneal washing in practice of gynecologic oncology.

CONTEXT: Peritoneal washing is performed for staging of gynecologic tumors to detect subclinical intraperitoneal metastases. AIM: The aim of the present study was to assess the impact of SurePath™ liquid-based cytology (LBC) in peritoneal washing in various gynecological malignancies. SETTINGS AND DESIGN: An audit of peritoneal-fluid/washing (January 2012 to July 2013) was performed with corresponding gynecologic specimens. All peritoneal washings were processed using both conventional and LBC technique. Suspicious cases on cytology were reported along with gynecologic specimens. RESULTS: There were a total of 393 peritoneal fluids. Eighty-three (21.1%) were positive for malignancy, and the corresponding histology was available in 352 (89.6%) cases. Sixty-nine positive samples had ovarian malignancies and 5 had uterine causes. There were 9 cases of peritoneal washings in which no histopathology was available. The most common cause of positive peritoneal cytology was ovarian serous carcinoma in 55/84 (65.5%) cases. Other causes included mucinous cystadenocarcinoma, dysgerminoma, squamous cell carcinoma in teratoma, yolk sac tumor, and granulosa cell tumor. Uterine causes included 2/45 (4.4%) cases of endometrioid adenocarcinoma, » (25%) cases of clear cell carcinoma, ½ (50%) cases of carcinosarcoma, and » (25%) cervix carcinoma. On review of positive cases (n = 83), 10 cases were identified, which had nil (n = 4) to low cellularity (<3 tumor clusters/smear; n = 6) on conventional smears, and were confirmed malignant on LBC. CONCLUSIONS: The most common ovarian malignancy causing positive peritoneal cytology is papillary serous carcinoma. Endometrioid adenocarcinoma rarely leads to positive peritoneal cytology. LBC technique leads to concentration of tumor cells causing reduction in false negative cases, especially in hemorrhagic and low-cellular cases.

Occurrence of Double Monoclonal Bands on Protein Electrophoresis: An Unusual Finding.

Various techniques of protein electrophoresis are used for detection of monoclonal proteins/paraproteins in serum and/or urine of patients with monoclonal gammopathies. These are detected as the so-called 'M' bands (monoclonal bands) on serum protein electrophoresis and/or immunofixation electrophoresis. In most cases, a single M-band is detected. However, more than one M-band can be detected in the samples of a minor proportion of patients. This condition is termed as 'double gammopathy' or 'biclonal gammopathy'. A knowledge of such an unusual occurrence is essential for recognition and appropriate interpretation of this entity.

Effect of antiretroviral therapy on hemoglobin A2 values can have implications in antenatal beta-thalassemia screening programs.

BACKGROUND: Raised hemoglobin-A2 (HbA2) is the diagnostic hallmark of beta-thalassemia trait (ßTT). Diagnostic difficulties may arise in HIV-positive patients on antiretroviral therapy (ART). We compared the effect of various antiretroviral drugs on HbA2 levels. We attempted to determine which drugs elevate HbA2 levels causing a false-positive diagnosis of ßTT and correlate the findings with red cell indices. METHODS: A retrospective analysis of the records of an antenatal thalassemia screening program was carried out for 78 HIV-positive adults (70 antenatal women and 8 husbands) to study the effect of antiretroviral drugs on HbA2 levels. Three had ßTT; 20 treatment-naïve subjects constituted controls. The effects of zidovudine (36 cases), stavudine (7 cases), and tenofovir (12 cases) were evaluated. High-performance liquid chromatography was done for HbA2 levels. Values of 3.5-3.9% were borderline and ≥ 4% with hypochromic microcytosis was considered to be ßTT. RESULTS: Twenty individuals not on ART had normal HbA2%. Three patients had ßTT and showed hypochromic microcytosis despite being on zidovudine. Fourteen of 55 patients on treatment (25.5%) had borderline HbA2 values (mean 3.7%): 11 were on a zidovudine-based regimen and 3 on a stavudine-based regimen. One patient on zidovudine had 4.1% HbA2 with normal Hb and severe macrocytosis (MCV 128.5 fl), leading to a false suspicion of ßTT. All patients on tenofovir had normal HbA2. Hematological parameters, including mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), and HbA2 levels were increased due to antiretroviral drugs zidovudine and stavudine. CONCLUSION: Treatment-naïve subjects and those on tenofovir showed no effect on HbA2 levels compared with zidovudine and stavudine. A proportion of patients on zidovudine or stavudine had borderline elevated HbA2 levels, which could lead to a false impression of ßTT.

Primary bone marrow lymphoma is a rare neoplasm with poor outcome: case series from single tertiary care centre and review of literature.

Primary bone marrow lymphoma is a rare disease and remains undiagnosed due to deceptive clinical presentation. Here, we report four cases of primary bone marrow B-cell non-Hodgkin lymphoma, which presented with cytopenias without any lymphadenopathy or organomegaly. Bone marrow examination revealed large atypical B-cells with a reactive T-cell infiltrate with suppression of the normal hematopoietic elements. This lymphoma is known to have a poor prognosis. Inspite of treatment, two of our patients died during chemotherapy. Two patients relapsed, of which one showed an early relapse after two months and was put on an alternative regimen. The other patient relapsed twice at an interval of 4 and 5 years, respectively, following which he remained in remission for another 5 years and had recently shown a relapse for the third time. Review of literature revealed seven case series and 11 case reports of primary bone marrow lymphoma in the last five decades.

A rare association of Sarcina with gastric adenocarcinoma diagnosed on fine-needle aspiration.

Sarcina is a Gram-positive anaerobic organism, having exclusively fermentative metabolism and has been associated with gastric outlet obstruction. We demonstrate the present case to highlight the presence of Sarcina with a coexisting gastric adenocarcinoma diagnosed on fine needle aspiration cytology.

Co-infection of Sarcina and Giardia in a child.

We present a case of 3-year-old boy who presented with vomiting and chronic diarrhoea, and the duodenal biopsy showed the presence of both Giardia and Sarcina. The clinical and pathological significance of Sarcina remains unknown in human beings and its co-existence with Giardia has not been reported.

Pulmonary inflammatory myofibroblastic tumor and IgG4-related inflammatory pseudotumor: a diagnostic dilemma.

IgG4-related inflammatory pseudotumor (IPT) and inflammatory myofibroblastic tumor (IMT) share morphological features like a prominent fibroblastic/myofibroblastic proliferation and the presence of inflammatory cells. Since IPT is managed conservatively and IMT is treated by surgical excision, it is important to differentiate these two lesions. The aim of this study is to highlight morphological and immunohistochemical features that distinguish IPT and IMT. Clinicopathological characteristics of cases diagnosed as pulmonary IPT or IMT from 1997 to 2013 were reviewed. The histological features were studied on hematoxylin and eosin-stained sections. Immunohistochemistry was done for IgG, IgG4, ALK-1, SMA, desmin, and CD34 for classification into IPT and IMT. Of the ten patients, seven were male and the age ranged from 4 to 58 years. The tumor size ranged from 1.5 to 4.0 cm in diameter. Histologically, proliferation of bland-looking spindle cells along with fibrosis and an inflammatory infiltrate comprising of lymphocytes and plasma cells were the common morphological features of both lesions. The spindle cell proliferation was more marked in IMT whereas lymphoplasmacytic infiltrate was more prominent in IPT. Obstructive phlebitis was observed only in cases of IPT. IgG4 expression was noted in IPT, and the number of IgG4-positive plasma cells and the ratio of IgG4+/IgG+ plasma cells were significantly lower in IMT than in IgG4-related IPT. Expression of anaplastic lymphoma kinase (ALK) was observed only in IMT, but not in IgG4-related IPT. The proportion of proliferating spindle cells, lymphoplasmacytic infiltrate, obstructive phlebitis, IgG4+ plasma cells and the ratio of IgG4+/IgG+ plasma cells, and ALK expression are helpful in differentiating these morphologically similar but biologically different lesions, which require different treatment modalities.
