Abstract
OBJECTIVE Evaluation of glucometrics in the first week of ICU stay and its association with outcomes. DESIGN Prospective observational study. SETTING Mixed ICU of teaching hospital. PATIENTS Adults initiated on insulin infusion for 2 consecutive blood glucose (BG) readings ≥180mg/dL. MAIN VARIABLES OF INTEREST Glucometrics calculated from the BG of first week of admission: hyperglycemia (BG>180mg/dL) and hypoglycemia (BG<70mg/dL) episodes; median, standard deviation (SD) and coefficient of variation (CV) of BG, glycemic lability index (GLI), time in target BG range (TIR). Factors influencing glucometrics and the association of glucometrics to patient outcomes analyzed. RESULTS A total of 5762 BG measurements in 100 patients of median age 55 years included. Glucometrics: hyperglycemia: 2253 (39%), hypoglycemia: 28 (0.48%), median BG: 169mg/dL (162-178.75), SD 31mg/dL (26-38.75), CV 18.6% (17.1-22.5), GLI: 718.5 [(mg/dL)2/h]/week (540.5-1131.5) and TIR 57% (50-67). Diabetes and higher APACHE II score were associated with higher SD and CV, and lower TIR. On multivariate regression, diabetes (p=0.009) and APACHE II score (p=0.016) were independently associated with higher SD. Higher SD and CV were associated with less vasopressor-free days; lower TIR with more blood-stream infections (BSI). Patients with higher SD, CV and GLI had a higher 28-day mortality. On multivariate analysis, GLI alone was associated with a higher mortality (OR 2.99, p=0.04). CONCLUSIONS Glycemic lability in the first week in ICU patients receiving insulin infusion is associated with higher mortality. Lower TIR is associated with more blood stream infections.

Abstract
AIM Malocclusion is an alteration of the normal relationships between skeletal, muscle and dental structures that can lead to impaired functionality as well as aesthetic alteration of the stomatognathic system. Functional alteration can affect various aspects, ranging from chewing ability to respiratory disorders. Paediatricians and dentists are called to prevent and diagnose these conditions as early as possible in order to preserve the patient's health. The purpose of this research is to study the incidence of malocclusion and its relationship with Obstructive Sleep Apnea Syndrome (OSAS) in a young population. Also, the role of paediatricians and dentists in prevention and early diagnosis of this condition was evaluated METHODS: An anonymous survey was given through Google form to 300 Italian children (139 males and 161 females) from different private dental practices in Italy. No personal information that identifies the individuals was collected, and the data was analysed in aggregate form only. All data was collected and statistically analysed. CONCLUSION The data highlight the patients' good attitude towards dental check-ups, which help to intercept malocclusions. Unlike the past, the knowledge of the importance of oral health and dental occlusion is high among young patients, parents and paediatricians. This study underlines the role of paediatricians as key players in the prevention of dental health problems.

Co-existence of type 1 diabetes and other autoimmune ailments in subjects with autoimmune thyroid disorders. Diabetes Metab Syndr 2022; 16:102405. [PMID: 35093687 DOI: 10.1016/j.dsx.2022.102405] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2021] [Revised: 01/14/2022] [Accepted: 01/16/2022] [Indexed: 10/19/2022]
Abstract
BACKGROUND AND AIMS Autoimmune thyroid dysfunction (AITD) is a significant autoimmune disorder affecting the population across age groups. The clustering of autoimmune diseases tends to occur within the same patients and families. Thus, this study aimed to determine the association of Type 1 diabetes and other autoimmune ailments in patients with autoimmune thyroid disorders. METHODS We performed a cross-sectional study, evaluating 500 subjects with a diagnosis of AITD (130 with Graves' disease; 370 with Hashimoto's thyroiditis) on presentation to our tertiary care centre to ascertain the prevalence of associated autoimmune disorders. RESULTS The frequency of Type 1 diabetes and other autoimmune disorders was 18.5% in Graves' disease and 27.8% in Hashimoto's thyroiditis patients. Coeliac disease (8.8%) (found in 6.9% of Graves' disease and 9.5% of Hashimoto's thyroiditis patients) and type 1 diabetes (7.8%) (found in 3.1% of Graves' disease and 9.5% of Hashimoto's thyroiditis patients) were the most common coexisting autoimmune disorders. Rheumatoid arthritis was the most common non-endocrine autoimmunity (2.8%). Female sex and duration of AITD more than five years were associated with increased odds of associated autoimmune disorders. CONCLUSION A high prevalence of associated autoimmune disorders was observed in subjects with autoimmune thyroid dysfunction. We suggest the patients who remain symptomatic and those who develop other symptoms even with appropriate treatment undergo screening for associated autoimmune disorders, thus preventing a delay in diagnosis.

Abstract
The review of literature shows that 48,22% of the autotranspated teeth were orthodontically treated. A 13-year-old male patient presented a destructive decay in the element 3.6, which was underoccluded. To maintain the arch space and the quantity of bone necessary for a potential implant, it was decided to perform an autotransplantation of the impacted element 3.8. Tooth autotransplantation is a valid and durable alternative to the prosthetic and the implant solutions with high success rate.

Abstract
The study analyzes how and if temporomandibular joint symptoms are influenced by different types of orthodontic therapy. Two-hundred-and-thirty-six adult orthodontic patients treated by different clinicians, were asked to complete a survey in which factors as the age, the gender and the type of device were considered. The questions were about the typical symptoms of temporomandibular disorders, in particular headache, bruxism, clenching, pain while opening the mouth and joint's noise. It was highlighted if these symptoms changed during the therapy and if they increased or decreased. The answers to our questionnaire revealed that the only statistically significative difference was related to bruxism, because we found a higher rate in patients treated with aligners than patients treated with metal braces, so we can suggest the fixed technique in the orthodontic patient who suffers of bruxism, even if further studies are required.

Abstract
Osteoporosis and fragility fractures are a major public health issue. Secondary osteoporosis is characterised by the presence of an underlying disease, deficiency, or use of a drug. Conditions that increase speculation for secondary osteoporosis include fragility fractures amongst the younger men or premenopausal women, markedly decreased Bone Mineral Density (BMD) values, and fractures despite conforming to anti-osteoporotic therapy. Since the emphasis is on the treatment of the primary disorder, a diagnosis of osteoporosis and thus the opportunity of preventive intervention can be missed. With this review, the authors objective is to emphasise the importance of secondary osteoporosis, discuss the causes and their mechanism and summarise treatment options.

Abstract
Histoplasmosis is a fungal infection caused by Histoplasma capsulatum and very few cases reported from North-West India. Adrenal histoplasmosis is an even more uncommon mycotic disease. We describe five immunocompetent men with adrenal histoplasmosis presenting with constitutional symptoms. Four patients had bilateral adrenal involvement, whereas one had unilateral adrenal mass. Three patients had adrenal insufficiency at presentation and the other two developed adrenal insufficiencies during follow-up. All the patients received amphotericin B and itraconazole treatment which led to symptomatic improvement but adrenal insufficiency persisted in all patients at the end of the follow-up.

Abstract
OBJECTIVE Efficacy of bilateral inferior petrosal sinus sampling (BIPSS) in corticotropin-dependent Cushing's syndrome (CS) for localization and lateralization of excess adrenocorticotropic hormone (ACTH) source, as compared to high-dose dexamethasone suppression test (HDDST) and magnetic resonance imaging (MRI) pituitary, respectively. METHODOLOGY Thirteen patients with clinically and biochemically confirmed CS underwent HDDST, MRI pituitary, and BIPSS by an experienced team of intervention neurologist, neurosurgeon, and endocrinologist using percutaneous femoral vein approach. RESULTS Of 13 patients (11 adults and two children) who underwent BIPSS, raised central to peripheral ACTH ratio was achieved in 12 cases, remaining one case being ectopic ACTH secretion (EAS). However, inter IPS gradient >1.4 was achieved in 11 (91.6%) of 12 Cushing's disease (CD) cases before vasopressin stimulation; and in 9 (75%) of 12 CD cases after vasopressin stimulation (P-value 0.583). HDDST suppression of more than 50% was present in only ten cases with CD, falsely negating CD in two cases (16.6%), sensitivity 83.3% and specificity 100%. MRI sella demonstrated pituitary microadenoma in 12 cases and macroadenoma in one case. Lateralization by BIPSS and MRI was concordant in 7 (58.3%) out of 12 cases with CD, with rate of remission after transsphenoidal surgery being higher in patients with concordant lateralization by BIPSS and MRI. CONCLUSIONS BIPSS is an important investigation to distinguish CD and EAS. BIPSS was superior to HDDST for confirming the source of excess ACTH. Our findings favor the use of BIPSS for localization and pituitary MRI for lateralization of microadenoma.

Abstract
A facile and eco-friendly green synthesis of silver-copper@zinc oxide (Ag-Cu@ZnO) nanocomposite using Acacia caesia flower extract and their application on catalytic reduction of toxic compounds and electrochemical sensing of nitrite ions are reported. The phytochemicals present in the extract were utilized for the Ag-Cu metal nanoparticles synthesis and also enhanced the binding capability between ZnO and Ag-Cu NPs. The synthesized nanocomposites were characterized by XRD, UV-Vis spectroscopy, Raman spectra, FTIR, SEM, TEM, EDX, XPS and ICP-AES for the formation of Ag-Cu NPs on ZnO. The Ag-Cu@ZnO nanocomposite showed better catalytic efficiency as compared to monometallic nanoparticles for 4-nitrophenol to 4-aminophenol conversion and Rhodamine B and Congo red dye degradation with 99% efficiency up to four cycles. The Ag-Cu@ZnO modified GC electrode showed enhanced catalytic activity towards nitrite oxidation, and it exhibited better performance compared to the other nanocomposites. An appreciable detection limit (17 μM) was achieved with excellent sensitivity for nitrite detection. The sensor was highly selective even in a many-fold higher concentration of co-existing interfering compounds. The good catalytic and electrochemical sensing is mainly ascribed due to the synergistic effect of Ag-Cu on the ZnO in the Ag-Cu@ZnO nanocomposite materials.

Abstract
The application of natural coagulants for decentralized water treatment is gaining importance as a part of global sustainable initiative. This study focuses on the isolation of active coagulation components responsible for water clarification with respect to Strychnos potatorum seeds. The active coagulant components, protein and polysaccharide, were successfully isolated, dialysed and subjected to gel permeation chromatography. The polysaccharide was isolated with the saline extraction method and characterized using FTIR and NMR spectroscopy. Protein was precipitated with 80% ammonium sulphate solution combined with dialysis and gel permeation chromatography using Sephadex G-50. SDS-PAGE revealed that the isolated protein has a molecular weight of 12 kDa. The small-scale coagulation assay suggests that the protein fraction has superior coagulation activity than the isolated polysaccharide residue. The active coagulant fractions reported in this study would be helpful in deploying cheaper and simple methods in scaling up the coagulant fraction from these seeds acting as a potential water treatment agent.

Abstract
OBJECTIVES Idiopathic hypogonadotropic hypogonadism (IHH) can be associated with anosmia/hyposmia. The objective of this study is to evaluate olfaction by Indian smell identification test (INSIT) and measure olfactory bulbs (OBs) and sulci using dedicated magnetic resonance imaging (MRI) in patients with IHH and correlate MRI findings with INSIT. METHODS Forty patients with IHH underwent (a) brief smell identification test (INSIT) and (b) MRI of the olfactory apparatus. The size of olfactory sulcus and bulb was quantified and compared with the normative data obtained in 22 controls. The agreement between INSIT and MRI was assessed using Kappa index. RESULTS Of the 40 patients, 8 patients who reported abnormal smell sensation and 12 of the remaining 32 patients who reported normal smell sensation historically had a low score on INSIT. Thus, there were 20 patients with Kallmann syndrome (KS) and the rest 20 were normosmic IHH (nIHH). Of 40 patients with IHH, MRI finding was suggestive of normal (n = 16), hypoplastic (n = 12), and aplastic (n = 12) olfactory apparatus. All 20 patients with KS have olfactory abnormalities (n = 12 aplastic, n = 8 hypoplastic), and 4 of 20 nIHH have olfactory abnormalities (hypoplastic only) on MRI. There is (a) significant positive correlation (r = 0.54, P = 0.013) between the OB volume (MRI) and smell test scores and (b) moderate agreement (Kappa index: 0.49) between smell defect (INSIT score ≤ 4) and aplastic olfactory apparatus. CONCLUSION Self-reporting of smell significantly underestimates olfactory phenotype, and hence we recommend an objective smell test to differentiate KS from nIHH. Olfactory phenotype significantly correlates with MRI quantification of olfactory apparatus in IHH.

Abstract
INTRODUCTION Type 1 diabetes mellitus (T1DM) is associated with various autoimmune disorders like celiac disease, thyroid disorder, adrenal failure, etc. However, how common is this association in Indian children is not clearly known. OBJECTIVE To assess the prevalence of other coexisting autoimmune disorders in children with T1DM. MATERIALS AND METHODS In this cross-sectional study, patients requiring insulin and ketosis-prone diabetic and with history of diabetic ketoacidosis/undetectable fasting C-peptide levels were included. Beside demographic and clinical data, detailed biochemistry evaluations were performed. Celiac disease was diagnosed as per the ESPGHAN diagnostic criteria. ACTH stimulation test was done to confirm the adrenal insufficiency in patients with basal serum cortisol <5 μg/dL. Thyroid function test (TSH) and anti-TPO antibody were assessed in all patients. Screening for other autoimmune disorders was done only when clinically indicated or symptoms or family history was suggestive of presence of such disorder. RESULTS Among 150 patients enrolled, 64.66% were males and mean age was 13.48 ± 3.29 years (range 3-18 years). Mean age at diagnosis of T1DM was 10.0 ± 3.63 years and duration of diabetes was 3.46 ± 3.18 years. The prevalence of antibodies positive against autoimmune diseases was anti-tTG IgA (20.7%), anti-TPO (33.7%), anti-CCP ab (1.3%), and ANA (0.7%). Significantly higher proportion of females had raised anti-TPO antibodies than males (47.2% vs. 25.8%, P = 0.006). Celiac disease was most common association (24.8%) followed by hypothyroidism (14.1%) and Grave's disease (3.3%). Significantly higher proportion of females had hypothyroidism than males (25.0% vs. 8.2%, respectively, P = 0.005). Prevalence of raised anti-tTG and anti-TPO did not differ significantly by the age (P = 0.841 and P = 0.067) or duration of T1DM (P = 0.493 and P = 0.399). CONCLUSION In this part of country, celiac disease, hypothyroidism, and Graves's disease are common associations in children with T1DM.

Abstract
Sestrins are highly conserved; stress inducible proteins that help maintain metabolic homeostasis and protect cells under stress conditions. They are up-regulated during stress and influence AMPK and mTOR pathways. Our objective was to find the role of Sestrin protein from Dictyostelium discoideum (Dd), a lower eukaryote where starvation stress initiates multicellular development. The single DdSesn-like gene was expressed and its endogenous functions were characterized. Both, the knockout and constitutively expressing strains were made and their involvement in starvation-induced autophagy was analyzed. Autophagic fluxes and ROS levels were also monitored. Additionally, overexpression of DdSesn decreased cell growth and showed a longer lag phase. Upon starvation both DdSesn and ROS levels increased. SesnOE showed reduced ROS levels while sesn- showed increased ROS levels when compared to the wild type. Therefore, we suggest that increased sesn expression may be beneficial in reducing ROS levels during starvation. Deletion of sesn showed reduced autophagic flux and increased p4EBP1 levels. We show that DdSesn promotes autophagy in D. discoideum upon starvation.

Abstract
BACKGROUND AND OBJECTIVE Type 2 diabetes mellitus (T2DM) may affect bone loss differentially in adult males and postmenopausal females. We evaluated the prevalence of osteoporosis in otherwise healthy adults with T2DM. MATERIALS AND METHODS In a cross-sectional study, adults with T2DM, aged 50 years and above, were evaluated for bone mineral density (BMD) using dual-energy X-ray absorptiometry (DXA) scan at spine and hip. T-score of ≤-2.5 was defined as osteoporosis and score -2.49 to -1.0 as osteopenia at either site. Correlation of low BMD with demographic, clinical, and laboratory parameters including serum Vitamin D and serum testosterone (in males) was evaluated. RESULTS In 200 patients, mean age was 64.5 ± 7.0 years and age differed significantly in males and females (P < 0.0001). Osteoporosis was present in 35.5% adults with T2DM. Significantly greater proportion of females had osteoporosis (49.5% vs. 22.3%, P < 0.0001). Frequency of osteoporosis at spine (33.5%) was higher than the same at hip (13.5%). Compared to males, significantly greater proportion of females had osteoporosis and osteopenia at both spine (P < 0.0001) and hip (P < 0.0001). Among all parameters assessed, a significant positive correlation of T-score at spine and hip was seen with body mass index in both males (r = 0.287, P = 0.003 at spine and r = 0.421, P < 0.0001 at hip) and females (r = 0.291, P = 0.004 at spine and r = 0.280, P = 0.010 at hip). There was no association of Vitamin D deficiency (45.5% patients) with either T-score and presence of osteoporosis either at spine (P = 0.388 and P = 0.177) or hip (P = 0.431 and P = 0.593). CONCLUSION Prevalence of osteoporosis in otherwise healthy T2DM was 35.5% with greater prevalence in females than males. Body mass but not Vitamin D or testosterone has an important role in the determination of bone loss in T2DM.

Abstract
Pilot scale thin film plate reactors (TFPR) were fabricated to study the solar photocatalytic treatment of wastewater obtained from the secondary treatment plant of a sugar refinery. Silver-impregnated titanium dioxide (TiO2) was prepared by a facile chemical reduction method, characterized, and immobilized onto the surface of ceramic tiles used in the pilot scale reactors. On 8 h of solar irradiation, percentage reduction of chemical oxygen demand (COD) of the wastewater by Ag/TiO2, pure TiO2, and control (without catalyst) TFPR was about 95, 86, and 22 % respectively. The effects of operational parameters such as, flow rate, pH, and addition of hydrogen peroxide (H2O2) were optimized as they influence the rate of COD reduction. Under 3 h of solar irradiation, 99 % COD reduction was observed at an optimum flow rate of 15 L h(-1), initial pH of 2, and addition of 5 mM of H2O2. The results show that Ag/TiO2 TFPR could be effectively used for the tertiary treatment of sugar refinery effluent using sunlight as the energy source. The treated water could be reused for industrial purposes, thus reducing the water footprint of the industry. Graphical Abstract Sugar refinery effluent treatment by solar photocatalytic TFPR.

Abstract
OBJECTIVE Objective was to evaluate reproductive hormones levels in hypothyroid women and impact of treatment on their levels. MATERIALS AND METHODS A total of 59 women with untreated primary hypothyroidism were included in this prospective study. Venous blood was taken at baseline and after euthyroidism was achieved for measuring serum free thyroxine, free triiodothyronine (FT3), thyroid stimulating hormone (TSH), prolactin (PRL), follicular stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), testosterone (T), and thyroid peroxidase antibody. Thirty-nine healthy women with regular menstrual cycles without any hormonal disturbances served as controls. The statistical analysis was performed using the Statistical Package for the Social Sciences Version 20 ([SPSS] IBM Corporation, Armonk, NY, USA). P < 0.05 was considered statistically significant. RESULTS On an average at diagnosis cases have more serum TSH (mean [M] = 77.85; standard error [SE] = 11.72), PRL (M = 39.65; SE = 4.13) and less serum E2 (M = 50.00; SE = 2.25) and T (M = 35.40; SE = 2.31) than after achieving euthyroidism (M = 1.74; SE = 0.73), (M = 16.04; SE = 0.84), (M = 76.25; SE = 2.60), and (M = 40.29; SE = 2.27), respectively. This difference was statistically significant t (58) = 6.48, P <0.05; t (58) = 6.49, P < 0.05; t (58) = 12.47; P < 0.05; and t (58) = 2.04, P < 0.05; respectively. Although average serum FSH (M = 12.14; SE = 0.40) and LH (M = 5.89; SE = 0.27) were lower in cases at diagnosis than after achieving euthyroidism (M = 12.70; SE = 0.40), (M = 6.22; SE = 0.25), respectively, but these differences were statistically insignificant t (58) = 1.61, P = 0.11; t (58) = 1.11, P = 0.27, respectively. CONCLUSION The study has demonstrated low E2 and T levels in hypothyroid women which were increased after achieving euthyroidism. Although average serum FSH and LH were increased in hypothyroid women after achieving euthyroidism but this difference was statistically insignificant.

Abstract
Congenital hypothyroidism (CH) is the one of the most common preventable cause of mental retardation. In the majority of patients, CH is caused by an abnormal development of the thyroid gland (thyroid dysgenesis) that is a sporadic disorder and accounts for 85% of cases and the remaining 15% of cases are caused by dyshormonogenesis. The clinical features of congenital hypothyroidism are so subtle that many newborn infants remain undiagnosed at birth and delayed diagnosis leads to the most severe outcome of CH, mental retardation, emphasizing the importance of neonatal screening. Dried capillary blood is used for screening and it is taken from heel prick optimally between 2 and 5 days of age. Blood spot TSH or thyroxine (T4) or both are being used for CH screening in different programs around the world. Neonates with abnormal thyroid screening tests should be recalled immediately for examination and a venipuncture blood sample should be drawn for confirmatory serum testing. Confirmatory serum should be tested for TSH and free T4, or total T4. Serum TSH and T4 undergo dynamic changes in the first weeks of life; it is important to compare serum results with age-normal reference ranges. Treatment should be started promptly and infant should be rendered euthyroid as early as possible, as there is an inverse relationship between intelligence quotient (IQ) and the age at diagnosis. Levothyroxine (l-thyroxine) is the treatment of choice and American academy of pediatrics and European society of pediatric endocrinology recommend 10-15μgm/kg/day as initial dose. The immediate goal of therapy is to normalize T4 within 2 weeks and TSH within one month. The overall goal of treatment is to ensure growth and neurodevelopmental outcomes as close as possible to their genetic potential.

Abstract
Pickardt syndrome (Pickardt-Fahlbusch syndrome) is a rare congenital syndrome characterized by tertiary hypothyroidism caused by the interruption of the portal veins between hypothalamus and adenohypophysis. Typical features of this syndrome are tertiary hypothyroidism with low thyroid stimulating hormone, hyperprolactinemia and other pituitary hormone deficiencies. Pituitary stalk interruption syndrome is characterized by a triad of thin or interrupted pituitary stalk, aplasia or hypoplasia of the anterior pituitary and absent or ectopic posterior pituitary (EPP) seen on magnetic resonance imaging (MRI). It is a congenital anomaly of pituitary whose exact prevalence is unknown. In some cases, it is restricted to EPP or pituitary stalk interruption. We are presenting the case history along with MRI finding of three children's who presented with short stature and delayed puberty.

Abstract
Hashimoto's encephalopathy (HE) is a rare steroid-responsive encephalopathy syndrome, which can have highly variable neuropsychiatric manifestations and can go unrecognized for a long time. HE is a diagnosis of exclusion and should be kept in mind when evaluating a patient with a cognitive dysfunction and high titers of anti-thyroid antibodies as it responds dramatically to steroids. Steroid responsive myoclonus can be a presentation of HE.

Transcriptional regulation of immediate-early gene response by THOC5, a member of mRNA export complex, contributes to the M-CSF-induced macrophage differentiation. Cell Death Dis 2013; 4:e879.

Abstract
Hematopoiesis and commitment to a restricted lineage are guided by a timely expressed set of cytokine receptors and their downstream transcription factors. A member of the mRNA export complex, THOC5 (suppressors of the transcriptional defects of hpr1 delta by overexpression complex 5) is a substrate for several tyrosine kinases such as macrophage colony-stimulating factor (M-CSF) receptor and various leukemogenic tyrosine kinases, such as Bcr-Abl, or NPM-ALK. THOC5 tyrosine phosphorylation is elevated in stem cells from patients with chronic myeloid leukemia, suggesting that THOC5 may be involved in leukemia development. THOC5 is also an essential element in the maintenance of hematopoiesis in adult mice. In this report, we show that THOC5 is located in the nuclear speckles, and that it is translocated from the nucleus to cytoplasm during M-CSF-induced bone marrow-derived macrophage differentiation. Furthermore, we have identified THOC5 target genes by trancriptome analysis, using tamoxifen-inducible THOC5 knockout macrophages. Although only 99 genes were downregulated in THOC5-depleted macrophages, half of the genes are involved in differentiation and/or migration. These include well-known regulators of myeloid differentiation inhibitor of DNA binding (Id)1, Id3, Smad family member 6 (Smad6) and Homeobox (Hox)A1. In addition, a subset of M-CSF-inducible genes, such as Ets family mRNAs are THOC5 target mRNAs. Upon depletion of THOC5, unspliced v-ets erythroblastosis virus E26 oncogene homolog (Ets1) mRNA was accumulated in the nucleus. Furthermore, THOC5 was recruited to chromatin where Ets1 was transcribed and bound to unspliced and spliced Ets1 transcripts, indicating that THOC5 has a role in processing/export of M-CSF-inducible genes. In conclusion, regulation of immediate-early gene response by THOC5, a member of mRNA export complex contributes to the M-CSF-induced macrophage differentiation.

Abstract
Thyroid hormone mediates growth and development of the skeleton through its direct effects and through its permissive effects on growth hormone. The effect of hypothyroidism on bone is well described in congenital hypothyroidism, but the impact of thyroid hormone deficiency on a growing skeleton, as it happens with juvenile hypothyroidism, is less defined. In addition, the extent to which the skeletal defects of juvenile hypothyroidism revert on the replacement of thyroid hormone is not known. A study was undertaken in 29 juvenile autoimmune hypothyroid patients to study the skeletal manifestations of juvenile hypothyroidism and the impact of treatment of hypothyroidism on the skeletal system of juvenile patients. Hypothyroidism has a profound impact on the skeletal system and delayed bone age, dwarfism, and thickened bands at the metaphyseal ends being the most common findings. Post treatment, skeletal findings like delayed bone age and dwarfism improved significantly, but there were no significant changes in enlargement of sella, presence of wormian bones, epihyseal dysgenesis, vertebral changes and thickened band at the metaphyseal ends. With the treatment of hypothyroidism, there is an exuberant advancement of bone age, the catch up of bone age being approximately double of the chronological age advancement.

Abstract
Total 33 obese patients were studied to determine correlation in between liver fat content with dyslipidemia and insulin resistance. Liver and spleen attenuation measurements were taken with three regions of interests (ROIs) from the liver and two ROIs from the spleen. Hepatic attenuation indices were measured as follows: (1) Hepatic parenchymal attenuation (CTLP); (2) liver to spleen attenuation ratio (LSratio); and (3) difference between hepatic and splenic attenuation (LSdif). Bivariate correlation analysis showed moderate but statistically significant negative correlation between CTLP, LSratio, and LSdif with body mass index, triglyceride, fasting plasma sugar, fasting plasma insulin, homeostasis model assessment-insulin resistance (HOMA IR), 2 h oral glucose tolerance test (OGTT), and statistically significant positive correlation with high density lipoprotein. Nonalcoholic fatty liver disease (NAFLD) is closely associated with features of the metabolic syndrome. The amount of intrahepatic fat closely correlates with the number of metabolic syndrome features. The values of CTLP, LSratio, and LSdif demonstrate strong inverse correlations with degree of steatosis.

Abstract
A total number of 140 type 2 diabetic patients with diabetic retinopathy (DR) were enrolled in the study from diabetic clinic during May 2011 till June 2012 to determine correlation between severity of DR with serum lipid and other modifiable risk factors in type 2 diabetic patients. Information including age, sex, height, body weight, body mass index (BMI), waist-hip ratio (WHR), and systolic and diastolic blood pressure was collected from each patient. Fasting plasma sugar, low density lipoprotein (LDL), triglyceride level (TG), high density lipoprotein (HDL), glycated hemoglobin (HbA1C), creatinine, and 24 h urinary albumin excretion was done for each patient. Estimated glomerular filtration rate (eGFR) was measured by modification of diet in renal disease (MDRD) equation. Patients were divided in five groups according to retinopathy status based on early treatment DR study (ETDRS) disease severity level. Statistical analysis was performed with Statistical Packages for Social Sciences (SPSS) statistical software (version 17.0 for Windows). The alpha level was set at P = 0.05 for all tests. Statistically significant positive correlation between severity of DR with systolic blood pressure P = 0.005 (r = 0.974), diastolic blood pressure P = 0.001(r = 0.994), LDL P = 0.005 (r = 0.976), TG P = 0.001 (r = 0.990), and 24 h urinary albumin P = 0.004 (r = 0.977) was documented. DR was also strongly positively correlated with smoking P = 0.017 (r = 0.941) and duration of diabetes P = 0.003 (r = 0.981). There was strong inverse correlation of DR with HDL P = 0.001 (r = -0.994) and eGFR P = 0.002 (r = -0.987). Serum lipids were significantly correlated with severity of DR.

Abstract
Mauriac syndrome is a rare syndrome associated with type 1 diabetes (T1DM) in children presenting with growth retardation, hepatomegaly, and cushingoid features. Recently, there has been re-emergence of this syndrome, especially with the use of premix insulin. A 15-year old type 1 diabetic boy, who was on premix insulin with erratic blood glucose, was referred to us for evaluation of short stature. He had significant short stature, hepatomegaly, and cushingoid features. His growth hormone (GH) stimulation was normal, and so was the overnight dexamethasone suppression test, based on which the diagnosis of Mauriac syndrome was reported. He was made to switch over to basal bolus regime, and was advised to follow-up for 6 months. He had reduction in hepatomegaly and a height gain of 3 cms.

Abstract
Pulse methylprednisolone therapy is the recommended therapy for moderate to severe and active ophthalmopathy, but high dose pulse methylprednisolone therapy is marred by the chances of fulminant hepatic failure and the high cost of therapy. Dexamethasone pulse therapy can be considered as an alternative to pulse methylprednisolone therapy. A prospective randomized control trial was carried out in 21 patients comparing pulse dexamethasone therapy versus pulse methyprednisolone therapy in Graves's ophthalmopathy. This study proved that pulse dexamethasone therapy is a cheaper and equally effective therapy for Graves's ophthalmopathy and the cost of therapy is reduced to at least 1/8(th) s. Furthermore, dexa had a better effect on reduction of exophthalmos. The dreaded complication of fulminant hepatic failure, associated with high dose of methylprednisolone, is not seen with dexa therapy.

Abstract
PURPOSE Aim of this study was to establish preliminary data on the variations of arterial supply of thyroid gland in Karnataka population. METHODS The anterior triangles in the neck of formalin fixed cadavers were dissected. The length, branching pattern, number and length of branches of superior thyroid artery (STA) were noted. We measured the length of inferior thyroid artery (ITA) from its point of emergence from thyrocervical trunk (TCT) to lower pole of thyroid gland. The length of the external carotid artery (ECA), TCT from the point of its emergence to the point of its branching was noted. We noted the number of branches from ITA and TCT. Presence of any additional artery supplying the thyroid gland was searched for. Difference in the length of STA and ITA between the two sexes and sides were noted. Statistical analysis was done by Student's t-test. RESULTS In our study the maximum length of STA was 5.34cm and that of ITA was 5.07cm and there were no statistically significant side-to-side differences in level of bifurcation. CONCLUSIONS Observations of the present study on the course and branching pattern of arteries around thyroid gland will help in easier approach during thyroid surgeries and interventional techniques (Tab. 1, Fig. 3, Ref. 38).

Abstract
BACKGROUND Celiac disease can have extra gastrointestinal tract (GIT) presentations, most of which are endocrine. The aim of this study was to present patients diagnosed to have celiac disease from an endocrine department and to study the prevalence of endocrinopathies in celiac disease. MATERIALS AND METHODS A total of 36 patients from the endocrinology department (LLRM Medical College, Meerut) between January 2011 and July 2012 and who were diagnosed to have celiac disease were included in the study. RESULTS Short stature was the commonest presentation (25%), other presentations included short stature and delayed puberty (20%), delayed puberty (11%), screening for celiac disease in type-1 DM patients (17%), rickets (6%), anemia not responding to oral therapy (6%), type-1 DM with recurrent hypoglycaemia (6%), and osteomalacia (3%). The endocrine manifestations include (after complete evaluation) short stature (58%), delayed puberty (31%), elevated alkaline phospahatase (67%), low calcium (22%), X-rays suggestive of osteomalacia or rickets (8%), capopedal spasm (6%), and night blindness (6%). Anti-TPO antibody positivity was found in 53%, hypothyroidism in 28%, subclinical hypothyroidism in 17%, and type-1 DM in 25% of the patients. A total of 14% patients had no GI symptoms. CONCLUSION Celiac disease is an endocrine disrupter as well as the great masquerader having varied presentations including short stature, delayed puberty, and rickets. Some patients who have celiac disease may not have any GI symptoms, making the diagnosis all the more difficult. Also, there is significant incidence of celiac disease with hypothyroidism and type-1 DM, making screening for it important in these diseases.

Abstract
INTRODUCTION Acanthosis nigricans is a non-specific reaction pattern that may accompany obesity, diabetes, excess corticosteroids, pineal tumors, malignancies, and other endocrine disorders. It is considered a cutaneous marker of tissue insulin resistance. AIMS AND OBJECTIVES To determine the prevalence of acanthosis nigricans in type 2 diabetes mellitus (DM) and its correlation with various anthropometric measurements and insulin resistance by HOMA-IR and other metabolic parameters. MATERIALS AND METHODS One hundred and fifty consecutive subjects with newly diagnosed type 2 DM, attending the endocrinology OPD of LLRM Medical College, Meerut were studied. Acanthosis was graded based on standard scale of 0-4 as described by Burke et al. Anthropometric data were obtained and insulin resistance calculated as HOMA-IR from fasting insulin and fasting blood sugar values. RESULTS The average age of the study population was 45.2 years, with male to female ratio of 1:5. The prevalence of acanthosis in males was 56.67% and in females was 86.92%. The acanthosis neck severity grading had a statistically significant correlation with fasting glucose levels, fasting insulin levels, and insulin resistance values: HOMA-IR, HOMA-S, and HOMA-B (P < 0.05). Other acanthosis parameters such as axillary grading, acanthosis at knuckles, and skin tags, did not have a statistically significant correlation with insulin resistance. CONCLUSION Acanthosis nigricans neck severity grading correlates well with insulin resistance and can be used as a clinical surrogate for assessment of severity of insulin resistance.

Abstract
BACKGROUND Wolfram syndrome is a rare hereditary or sporadic neurodegenerative disorder also known as DIDMOAD. The classically described presentation is of insulin-dependent diabetes, followed by optic atrophy, central diabetes insipidus, and sensory neural deafness. Also included are less well-described presentations of Wolframs syndrome. We here present three cases of atypical presentation of this syndrome. CASE 1: A 15-year-old boy with insulin-dependent diabetes was presented for evaluation of depressive symptoms associated with suicidal tendency. Neuropsychiatric manifestations are described with Wolframs syndrome, and wolframin gene, in recessive inheritance, is associated with psychiatric illnesses without other manifestations of Wolframs syndrome. CASE 2: A 17-year-old diabetic boy on insulin with good control of blood sugar presented for evaluation of delayed puberty. Central hypogonadism and other anterior pituitary hormone dysfunctions are the less publicized hormone dysfunctions in Wolframs syndrome. CASE 3: A 23-year-old female who was on insulin for diabetes for the past 14 years, got admitted for evaluation of sudden loss of vision. This patient had developed a vitreous hemorrhage and, on evaluation, was found to have optic atrophy, sensory neural hearing loss, and diabetes insipidus, and presented differently from the gradual loss of vision described in Wolframs syndrome. CONCLUSION Wolframs syndrome being a multisystem degenerative disorder can have myriad other manifestations than the classically described features. Neuropsychiatric manifestations, depression with suicidal risk, central hypogonadism, and secondary adrenal insufficiency are among the less well-described manifestations of this syndrome.

Abstract
The underlying causative agent in the majority of patients with chronic liver disease is ethanol; the rest of the cases are largely viral in aetiology (hepatitis B or C viruses). Nutrition supplementation improves the quality of life and decreases morbidity in chronic liver disease, but evidence that it prolongs long-term survival is lacking. The situation is very different in chronic liver disease patients who receive a liver transplant, however, with better pretransplantation nutrition status predicting a distinctly improved survival after transplantation.

Abstract
Levels of intracellular calcium, (Ca(2+))(i), from different stages of cell cycle of Dictyostelium discoideum were monitored using the fluorescent Ca(2+)-sensitive dye, Indo 1. Combinations of Ca(2+)-ionophore (A23187) and Ca(2+)-chelator (EGTA) resulted in the inhibition of progression of cell cycle. This delay was caused due to block in G(2)/M-->S phase transition of the cell cycle. Rescue of the cell cycle progression was made with 0.5 m m of exogenous Ca(2+). High (Ca(2+))(i)levels overlapped with the S-phase, of the cell cycle.Results indicate that a high (Ca(2+))(i)level during S-phase is not required for cell cycle progression but for cell-type choice mechanism at the onset of starvation, and these cells tend to follow the prestalk pathway.

Abstract
This is the first report correlating levels of polyamines and its fractions with differentiation in Dictyostelium discoideum. Temporal changes in endogenous levels of free, conjugated and bound putrescine, spermidine and spermine were analysed at critical stages of morphogenesis in this organism. No spermine was found at any given stage and putrescine was the most abundant polyamine. There was a sharp increase in the levels of both free (and total) and conjugated forms of putrescine and spermidine at the slug stage as compared to the growth phase. The levels of putrescine and spermidine were found to be higher in isolated prespore cells as compared to the prestalk cells. Remarkably, the levels of polyamine decreased at the early culminant stage. Data suggest that a moderate level of polyamines is needed for growth but it is important to have high levels of polyamines at the time of differentiation.

Calcium levels correlate with cell cycle phase and affect the level of the cyclin B transcript in Dictyostelium discoideum. FEMS Microbiol Lett 1998; 161:193-9.

Abstract
In pre-aggregation amoebae of Dictyostelium discoideum, phenotypic differences with respect to cellular Ca2+ and cell cycle phases are known to bias post-aggregative cell-type choice. Using chlortetracycline fluorescence as an indicator, we found that cellular Ca2+ is highest at the S phase of the cell cycle. Upon increasing the level of Ca2+ with the help of the calcium ionophore A23187, there is a significant decrease in the cyclin B (clb1) mRNA level; the cdc2 mRNA level shows a marginal decrease. These results suggest that the effect of Ca2+ and the cell cycle on cell fate could be exerted at the level of transcription, or message stability, of specific genes.

Immunotechnological trends in radioimmunotargeting: from 'magic bullet' to 'smart bomb'. Nucl Med Commun 1995; 16:66-75.

Abstract
The impact of recent advances in the chemical and genetic engineering manipulations of antibodies on radioimmunotargeting is reviewed both in relation to radioimmunoscintigraphy and radioimmunotherapy. The resulting trends are: (1) the linking of parts of the mouse/rat and human antibody molecule; (2) the creation of molecules with dual antigen or multiple antigen recognition capabilities; (3) the making of smaller and smaller antigen recognition molecules; and (4) the development of molecules with dual capabilities, e.g. antigen recognition and enzyme activity. The various methods of creating antibodies in vitro are reviewed with reference to bacteria, using phage selection and a combinatorial library, mammalian cells, yeast cells and, finally, mice containing giant yeast artificial chromosomes. The advantages and disadvantages of smaller fragments as well as of the human anti-mouse antibody (HAMA) reaction are discussed and the need for early clinical evaluation and widespread availability of the newer antibodies is emphasized. It is envisaged that these immunotechnological advances will permit the large-scale production of precisely engineered humanized antibodies, and the specificity and affinity rate constant of these antibodies can be optimized using in vitro phage selection as well as by computer modelling where the stereo chemistry of the antigen is known precisely.

The level of sequestered calcium in vegetative amoebae of Dictyostelium discoideum can predict post-aggregative cell fate. Differentiation 1994; 57:163-9.

Abstract
When freshly starved amoebae of Dictyostelium discoideum are stained with chlortetracycline (CTC), a cell type-specific fluorescent probe for membrane-associated calcium (CA2+) the resulting fluorescence distribution falls into two functional classes. Fluorescence-activated cell sorting shows that highly fluorescing amoebae tend to enter the prestalk pathway while those with low fluorescence tend to become prespores. In the light of previous findings, these results indicate that in addition to cell cycle phase at starvation, phenotypic variation in the level of sequestered calcium is an early correlate of cell fate.

Abstract
A new method is described for measuring intracellular free calcium concentrations, [(Ca2+)i], in the cells of Dictyostelium discoideum transformed with apoaequorin cDNA of the jellyfish, Aequorea victoria. Aequorin, a calcium-specific indicator, was regenerated in vivo from apoaequorin produced in the cells by incubation with coelenterazine. The results showed that [(Ca2+)i] in developing cells markedly increases at the aggregation stage and again at the culmination stage after a temporary drop at the migration stage. Except for the vegetative stage, the cells at all stages of development exhibit a sharp transient increase in [(Ca2+)i] upon stimulation with a cAMP (50 nM) pulse, high responses being observed at the migration and culmination stages. Separated prestalk cells of migrating slugs contain more than twice as much [(Ca2+)i] and show three times as large a response to cAMP stimulation as prespore cells.
