Introduction: Radioiodine therapy is a standard procedure in thyroid autonomy treatment. Discrepancies in the visual comparisons of the scintigraphies prepared for this purpose using Tc-99m-O4- and I-131 have been known for years. In this study a new method is used to calculate and perform a quantitative comparison of both uptakes using subtraction analysis and 3D imaging. The results and their causes are discussed together with practice-relevant conclusions for better clinical results.
Material and Methods: The new method was used in 38 patients with thyroid autonomies for the subtraction analysis of standardized pretherapeutic and intratherapeutic scintigraphies. The parametric distribution of activity was calculated absolutely and as a percentage and displayed three-dimensionally. These results were compared with the visual assessment of the different scintigraphies by the experts. Inclusion criteria were pretherapeutic and intratherapeutic hyperthyroidism without medication affecting the thyroid. The time difference between acquiring the scintigraphies was 28 days maximum.
Results: Activity distribution was visually discrepant in 39.5% of cases. 60.5% displayed comparable uptake. The calculated values showed reversed results after applying the new method. The results using our method show a higher rate of calculated discrepancies compared with visual analysis.
Conclusion: Accurate functional imaging of the thyroid is next to further aspects very important in establishing the diagnosis and deciding about the therapy activity for thyroid treatment. In combination with clinical symptoms and laboratory values, Tc-99m-O4 - scintigram can be used for an orientated, preliminary assessment of functional disorders of the thyroid. But because of the higher rate of found discrepancies, the solely use of Tc-99m-O4 - scintigram is not always capable for exact and reliable diagnosis. The known reason for this is most probably due to the different biokinetics of both radiopharmaceuticals, which can be imaged more sensitively with this method. Consequently, a scintigram should be performed in the pretherapeutic radioiodine uptake test. Despite higher costs and radiation exposure, alternatively, pretherapeutic use of other diagnostic iodine isotopes like I-123 or -124 should be discussed, because they could overcome the limitation of the different biokinetics. Following this approach the preliminary assessment using Tc-99m-O4 - scintigraphy can be precised and double checked to improve diagnostic confi dence and treatment results for a better outcome of the patients.
This report presents an adult patient suffering from sacroiliitis like low back pain, lumbosacral radiculopathy and elbow swelling. Multimodality imaging revealed multiple lytic bone lesions located in supra acetabular iliac bone, sacrum, and distal end of radius. Painful numerous lesions due to the extension to the articular surfaces are not expected for Brown tumors. Less than ten cases with multiple Brown tumor due to primary hyperparathyroidism has been reported. Although Brown tumors are mostly diagnosed incidentally, this case would awake the physicians about rheumatological symptoms in the presentation of Brown tumors. Since Brown tumors are non-touch bone lesions that are expected to regress after parathyroid adenoma removal, it is important to distinguish Brown tumors from the giant cell tumors.
Objective: In end stage renal disease, the synthesis of vitamin D is disturbed.Hyperparathyroidism is one of the key factors in the pathogenesis of many of the complications of dialysis mainly bone and cardiovascular complications.Aim:This study aimed at assessing vitamin D receptor gene polymorphisms BsmIand FokI in Egyptian patients with end stage renal disease on maintenance haemodialysis and the assosciation of these polymorphisms with cardiovascular complications and hyperparathyroidism among these patients.
Methods: One hundred subjects, recruited from Medical Research Institute, from March to July 2014, divided into two main groups; the control group which included thirty apparently healthy subjects and the patients group which included seventy patients with end stage renal disease on maintenance haemodialysis with median 4 years. To all studied subjects, detailed history was taken, thorough physical examination, carotid intima media thickness, presence of plaques and ECG ischemic changes. Laboratory investigations included serum levels of: glucouse, urea, creatinine, uric acid, albumin, total cholesterol, low and high density lipoproteins, calcium, phosphorus, and CRP as well as plasma PTH level. For molecular studies, the detection of BsmI and FokI polymorphisms using polymerase chain reaction and restriction fragment length polymorphism (PCR / RFLP) technique.
Results: 1.No statistically significant difference could be detected in both BsmI and FokI gene polymorphisms between the hemodialysis patients and the controls, suggesting that the development of ESRD had no relation with either VDR BsmI or FokI gene polymorphisms.2.No statistically significant difference were found in these polymorphisms between the hemodialysis patients with or without cardiovascular complications or between patients with PTH level less or more than 300 pg/ml. These results suggest that the development of cardiovascular complications and secondary hyperparathyroidism among Egyptian patients on maintenance haemodialysis cannot be attributed to these two gene polymorphisms.
Conclusion: No association could be found between the variant alleles of BsmI and FokI gene polymorphisms and the development of ESRD, cardiovascular complications and secondary hyperparathyroidism among the studied samples of Egyptian patients on maintenance haemodialysis.
Objective: To assess the knowledge, attitudes, and skills in pre-hospital care and emergency medicine of doctors, nurses and Emergency Medical Technicians (EMT), who accompanied emergency patients in ambulances?
Methods: A descriptive cross-sectional study was conducted among the doctors, nurses, and EMT who accompanied emergency patients in ambulances to the National Hospital. All ambulances arriving from August to October 2008 (n=409) were screened. A self-administered questionnaire with 30 items was used to assess knowledge, attitudes, and skills. The knowledge was categorized into three levels, EMT-basic level, EMT-intermediate level, and EMT-paramedic level and the scores were converted into the percentages.
Results: The overall knowledge score on basic, intermediate and paramedic level were 57.5%, 42.9%, and 33.9% respectively. The knowledge on airway management (84.3%), bleeding control (82.9%), patient transport (71%) and first aids (61%) at the EMT-basic level were higher, however oxygen administration (37.1%) and basic life support (38.6%), spinal immobilization (45.7%), traction splinting (47%) and triage (48.6%) were lower. For the EMT-intermediate level, knowledge on endotracheal intubation (41.4%) and initial cardiac drug therapy (44.3%) were low. For the EMT-paramedic level, the knowledge on the advanced respiratory support (53%), ECG interpretation (37%), pharmacology (13%) and paediatric life support (20%) were lower.
Most staff showed positive attitudes towards the need of basic knowledge in pre-hospital care (97.1%, n=34), need for proper training (97.1%, n=34) and cost for pre-hospital care (77.1%, n=27), while they showed relatively negative attitudes towards the outcome of pre-hospital care (74.3%, n=26).
For the required skills for advanced life support, most of the staff showed skills in IV cannulation (71.4%, n=25) and IV drug administration (71.4%, n=25) however less skills were shown cricothyroidotomy (22.9%, n=8), pleural drainage (25.7%, n=9) and laryngoscopy and intubation (31.4%, n=11).
Conclusion: The knowledge at the EMT-basic level was average and intermediate and paramedic levels were lower than average. The attitudes were generally positive. However they lacked some specific skills.
Objective: This study aimed to investigating of the epidemiological aspects of infertility and related risk factors in infertile women.
Materials and methods: This cross-sectional study, carried out on 330 infertile women referred to two infertility treatment center of Imam Khomeini Hospital and Mother center in Sari, Iran, from April 2015 to March 2017.
Results: 54.5% of these women were in the age of 30-39 years, infertility duration in 55.2% was 1-5 years, Body mass index (BMI) in 44.5% of samples was 26-30 kg/m2, 54.5% had diploma and associate degree. 63.6% lived in urban areas. 74.5 % of patients reported primary infertility. History of polycystic ovarian syndrome (PCOs) and pelvic inflammatory disease (PID) and poor ovarian reserve were the most common causes and risk factors for the infertility with prevalence 19.42%, 16.81% and 13.91%, respectively. Most underlying disease was thyroid disorders (54.5%). There was found statistically significant relationship between residents of urban areas and infertility duration, endometriosis and educational levels, miscarriage with thyroid. Data analysis performed using IBM SPSS 21 software and Chi-Square test (p < 0.05).
Conclusion: The results showed that women with infertility in north of Iran were more likely to be older, less educated, and also had overweight. They are more possible to have ovarian disorders. In these area, thyroid disease more common like Iodine deficient regions. Future research should be focused on the reasons why majority of women don’t seek treatment for the underline significant diseases that may be effects on ovarian function and fertility.
During the last few decades painstaking efforts have been made to eliminate iodine deficiency throughout the world. Todays in regions where dietary iodine intake is adequate or borderline, the main focus is increasing dietary iodine supply in the target population during pregnancy and the first years of life.
Objective: The aim of this study was to obtain longitudinal data on urinary iodine excretion and the changes of maternal thyroid parameters in two groups of healthy women with mild-to-moderate iodine deficiency and iodine sufficiency residing in an iodine replete area of Tehran capital city of IR Iran, for more than one decade.
Research designs and methods: The present study is part of a cohort study, investigating the relative influences of iodine intake on thyroid size and function of mothers and their infants during and after pregnancy. A total of 500 pregnant women enrolled from two mother-child health care centers and was divided into group I, with median urinary iodine excretion (MUIE) < 150 µg/L, and group II with MUIE ≥ 150 µg/L. Sonographic thyroid volume measurement, urinary iodine excretion and thyroid function tests were measured sequentially in all pregnant women during the three trimesters (T) of pregnancy.
Results: The mean ± SD age of the participants was 25.1 ± 5.1 years. The MUIE in group I and II in the first, second and third trimester were 123 and 250 µg/L, 127 and 166 µg/L, 120 and 150 µg/L, respectively. The MUIE in the third trimester of pregnancy in group I did not differ significantly from the values in the first and second trimesters (p = 0.67), but it did decline significantly in group II (p < 0.001). The median thyroid volume of subjects, in the first, second and third trimesters were 7.8, 8.2 and 8.1 ml in group I and 7.5, 8.0 and 8.4 ml in group II, respectively. No difference in thyroid volume was found between two groups in each of the three trimesters of pregnancy (p > 0.05). The mean (± SD) TSH concentration of subjects in first, second and third trimester was 2.3(± 2.6), 2.1(± 1.8), 2.3(± 1.7) mIU/L in group I and 2.1(± 3.1), 2.1(± 1.8) and 2.0(± 1.3) mIU/L in group II, respectively. The trend of TSH rising in group I was 26.7% and in group II it was 13.3%. The mean TSH value in three trimesters did not differ significantly in either groups (p > 0.05). The mean (± SD) total T4 concentrations of subjects in first, second and third trimesters were 13.2(± 3.4), 13.8(± 3.3), 13.0(± 2.9) µg/dl in group I and 13.1(± 3.2), 13.7(± 2.9), 13.4(± 3.2) µg/dl in group II, respectively. The mean total T4 value in three trimesters did not differ significantly in either groups (p > 0.05). There was no correlation between the thyroid volume and three observed parameters (UIE, total T4 and TSH) during the pregnancy in either groups.
Conclusion: Even in areas with well-established universal salt iodization program, pregnancy could be a risk of having iodine deficiency and systematic dietary fortification needs to be implemented in this vulnerable group.
During the last few decades painstaking efforts have been made to eliminate iodine deficiency through the world. Nowadays in regions where dietary iodine intake is adequate or borderline, the main focus is increasing dietary iodine supply in the target population during pregnancy and the first years of life. Severe iodine deficiency during pregnancy increases the risk of irreversible brain damage, intellectual disability, neurologic abnormalities, stunted growth, increased pregnancy loss, infant mortality, impairments in child development and cretinism. The potential effects of mild-to-moderate iodine deficiency are debated. Results from animal studies and observational human studies indicate that maternal mild-to-moderate iodine deficiency disturbs thyroid function in pregnancy and it also may affects fetal neurodevelopment. The effect of supplementation of iodine on thyroid function of pregnant women and their newborn, neurodevelopment of infants and cognitive performance of children have been investigated using iodine nutrition in pregnancy, based on median urinary iodine concentration. However they have found conflicting results regarding the benefits or harms of iodine supplementation in pregnancy. Although many epidemiological, interventional and clinical studies have supported the association between thyroid function in pregnant women and later psychomotor and mental development of their children, the effect of iodine supplementation in pregnant women on neurodevelopment of children is inconclusive. Even in areas with well-established universal salt iodization program, pregnancy could be at risk of having iodine deficiency and despite WHO/ICCIDD/UNICEF recommendation which believe that dietary iodine fortification during pregnancy depends primarily on the extent of pre-existing iodine deprivation, systematic dietary fortification needs to be implemented in this vulnerable group. However, iodine supplementation of mildly iodine deficient pregnant women may not have beneficial effects in their thyroid function or neurodevelopment of their children.
Primary sources document Dr. Saul Hertz (1905 - 1950) as conceiving and developing radioiodine (RAI) as a diagnostic tool and as a therapy for thyroid diseases. Dr. Hertz was the first and foremost person to develop the experimental data on RAI and apply it to the clinical setting.
Saul Hertz was born on April 20,1905 to Jewish parents who had immigrated to Cleveland, Ohio. He received his A.B. from the University of Michigan in 1925 with Phi Beta Kappa honors. After graduating from Harvard Medical School in 1929, at a time of quotas for outsiders, he fulfilled his internship and residency at Cleveland’s Mt. Sinai Hospital.
In 1931, he came back to Boston to join the newly formed Thyroid Unit at The Massachusetts General Hospital serving as the Chief from 1931 - 1943.
Celiac disease affects 1% of the world population; however it is under diagnosed in UAE. The disease has many clinical manifestations, ranging from severe malabsorption to minimally symptomatic or non-symptomatic presentation. Hypocalcaemia is a common finding in celiac disease and could be the only presentation of the disease; however hypercalcemia has been previously reported in patients with celiac disease either due to primary hyperparathyroidism or tertiary hyperparathyroidism due to prolonged hypocalcaemia. A normal calcium level on the other hand in patients with untreated celiac disease who also have primary hyperparathyroidism can be due to interplay of these two conditions and may delay the diagnosis of primary Hyperparathyroidism. We report the very first case from our practice in UAE with untreated celiac disease and normal calcium level at presentation, where a diagnosis of primary hyperparathyroidism was not entertained initially. Patient went on gluten free diet which then caused normalization of intestinal abnormalities and likely calcium absorption manifesting as hypercalcemia on subsequent labs. This led to further work up and finally the diagnosis of Primary hyperparathyroidism due to parathyroid adenoma.
Asthma is a chronic respiratory disease characterized by chronic airway inflammation. Common manifestations of asthma include wheezing, chest tightness, cough, shortness of breath. Diagnosis of asthma requires clinical documentation of respiratory symptoms, exacerbation of symptoms following exposure to triggers, as well as demonstration of expiratory airflow obstruction. Wheeze is a continuous sound, lasting longer than 0.25 s that is produced by oscillation of opposing airway walls [1,2]. Wheezing, although a typical symptom of asthma, can also be caused by other diseases. Apart from asthma, wheezing can be due to extra-thoracic upper airway obstruction, intrathoracic upper airway obstruction, lower airway obstruction.
Benign multimodal goiter is a common disease, that rarely causes upper airway obstruction. Retrosternal goiter should be taken into account the differential diagnosis of upper airway obstruction . The respiratory symptoms of a retrosternal goiter may be masked for years due to the slow growth of the goiter. Patients commonly complain of respiratory symptoms if tracheal diameter is narrowed more than 50% from the normal size. Respiratory symptoms may be suddenly precipitated by spontaneous or traumatically induced bleeding into the substernal goiter, as well as by tracheal infections . Clinical management of this condition is really challenging. Diagnosis is also not straightforward, as clinical suspicion is needed. There are cases of retrosternal goiter mimicking asthma that remain undiagnosed for many years. Retrosternal goiter should be taken into account in the differential diagnosis of patients diagnosed as suffering from asthma, and presenting no improvement despite medical therapy. In addition, it should be taken into account that sudden gland enlargement due to hormonal changes might lead to life threatening upper airway obstruction with clinical picture similar to bronchial asthma attack . In a recent very interesting case report, the authors present a case of a pregnant woman in the second trimester who presented with an acute airway obstruction due to the enlargement of a retrosternal goiter .
Goiters are the more common masses of the superior mediastinum [6,7]. Commonly, retrosternal goiter is due to the extension in the thorax of a cervical goiter. However, rarely, it may represent primary disease due to the growth of ectopic thyroid tissue. In addition, retrosternal goiter may develop in patient submitted to thyroidectomy due to cervical multinodular goiter . Although retrosternal goiters are commonly asymptomatic, symptoms may include dyspnea, stridor, hoarseness, dysphagia, superior vena cava syndrome, transient ischemic attacks, cerebral edema, Horner’s syndrome, and thyrotoxicosis . Diagnosis could be verified by neck and chest radiography, thorax CT and MRI. Chest radiography commonly shows a widened mediastinum with a superior mediastinal mass causing compression of the trachea as well as deviation of the trachea to the right. Mediastinal computed tomography reveals a mass that is extension of the thyroid gland. The presence of respiratory symptoms in a patient with retrosternal goiter is an indication for surgery. The majority of retrosternal goiters can be approached through a cervical approach [9,10].
Acute pancreatitis forms a major bulk of our inpatient admission due to gall stone disease. Diagnosis of acute pancreatitis remains a challenge even now. Serum amylase remains the most commonly used biochemical marker for its diagnosis but its sensitivity can be reduced by late presentation, hyper-triglyceridemia and chronic alcoholism. We conducted a study to determine the levels of serum and urinary amylase in patients with acute pancreatitis and compared their sensitivity and correlation with CT findings vis-à-vis the severity of the disease. The study was taken as a post graduate research model in the Post graduate Department of General and Minimal Access Surgery, Govt. Medical College Srinagar, J&K, India 2014-2016 and submitted for the award of masters in General Surgery. A total number of 150 patients were enrolled in the studies which were admitted in our unit as acute pancreatitis. 73 (48.7%) belonged to the age group of 30-44 years, 15(10%) patients aged >60 years with 86 (57.3%) males and 64 (42.7%) females. We had 81 (54%) patients with biliary tract diseases, followed by 21 (14%) patients with worm induced, 20 (13.3%) had hyperlipidaemia and only 4 (2.7%) patients had post ERCP etiology. Tenderness in epigastrium was the presenting sign in 111 (74%), followed by chest signs in 25 (16.7%) patients, diffuse tenderness in 19 (12.7%), icterus in 11 (7.3%), low grade fever in 9 (6%) patients, shock in 5 (3.3%). Diabetes mellitus as a comorbidity was observed in 48 (32%) patients followed by hypothyroidism 37 (24.7%) patients. Hypertension was seen in 31 (20.7%) patients, COPD in 19 (12.7%) patients and obesity in 13 (8.7%) patients. Twenty two (14.7%) needed ICU admission; while as 128 (85.3%) were managed in the general ward. All the enrolled patients in our study were managed conservatively. Out of a total of 150 patients, 148 (98.7%) survived while as only 2 (1.3%) of our patients expired. At the time of admission in the hospital, 120 (80%) patients had serum amylase level of >450 U/L, 19 (12.7%) patients had 150-450 U/L levels while as 11 (7.3%) patients had <150 U/L serum amylase levels. CT has been shown to yield an early overall detection rate of 90% with close to 100% sensitivity after 4 days for pancreatic gland necrosis. The correlation of urinary amylase with the CECT Severity Scoring in a patient of acute pancreatitis is still ambiguous.
The normal levels of thyroid hormones (THs; thyroxine, T4 & 3,5,3′-triiodo-L-thyronine, T3) are necessary for the normal development [1-48], particularly the fetal and neonatal cardiac growth and development . The actions of THs are facilitated genomically by thyroid receptors (TRs, α and β) and non-genomically at the plasma membrane, in the cytoplasm and in cellular organelles [4,49-55], by stimulation of Na+, K+, Ca2+ and glucose transport, activation of protein kinase C (PKC), protein kinase A (PKA) and mitogen activated and protein kinase (ERK/MAPK) . In addition, the transport of T4 and T3 in and out of cells is controlled by several classes of transmembrane TH-transporters (THTs) , including members of the organic anion transporter family (OATP), L-type amino acid transporters (LATs), Na+/Taurocholate cotransporting polypeptide (NTCP), and monocarboxylate transporters (MCTs) [4,49,57,58]. Adding additional complexity, the metabolism of T4 and T3 is regulated by 3 selenoenzyme iodothyronine deiodinases (Ds: D1, D2 and D3) [59-61]. On the other hand, the congenital hypothyroidism can cause the following [49,62-64], (1) congenital heart diseases; (2) diastolic hypertension; (3) reduced cardiac output, stroke volume and a narrow pulse pressure; (4) dilatation and overt heart failure; (5) elevation in the systemic vascular resistance [65-68]. Similarly, the chronic hyperthyroidism can cause the following [49,64]: (1) cardiac hypertrophy; (2) increase in the cardiomyocyte (CM) length rather than width; (3) noticeable diminution in systemic vascular resistance; (4) elevation in the cardiac contractility; (5) systolic hypertension; (6) increase in the cardiac output, venous volume return, blood volume and pulse pressure; and (7) reduction in the systemic vascular resistance [49,69]. T3-therapy can induce DNA synthesis and cardiomyocyte proliferation, and improve the cardiac contractility; though, this action is as still unidentified [49,70-74].
Background: Hypoparathyroidism is well known to occur in thalassemia major patients, but it is thought to be uncommon and its incidence is considered to be decreasing with improvements in chelation therapy. The objective of this study was to assess the prevalence of parathyroid dysfunction in the first decade of life of the patients with thalassemia major.
Patients and Methods: Ninety children with beta-thalassemia major (55 males and 35 females) with a mean age of 7.17±3.78 years (1-13 years) and age and sex matched control group of 60 healthy children (36 males and 24 females) with a mean age 6.98±3.66 years (1-13) years. Serum parathyroid hormone (PTH), serum total Calcium (Ca), serum phosphorus (P), serum alkaline phosphatase (ALP), serum 25-hydroxyvitamin D (25-OHD) and serum ferritin levels were measured.
Result: PTH levels were higher than normal range in 23 (25.6%) patients with a mean value of 75.2±31.3 µg/mL compared to those having normal range level (35.3±15.2 µg/mL). Ca levels were found low in 11 patients (12.2%), and P levels were found high in 2 (2.22%) and low in 4 (4.44%) patients while high ALP levels were found in 6 (6.67%) patients. 25-OHD levels were low in all patients with a mean value of 24.95±5.82.
Conclusion: Reports in the literature indicate that parathyroid dysfunction due to iron overload generally occurs in 2nd or 3rd decade of patients with thalassemia major. However, our study shows that PTH due to iron overload may develop in a significant number of thalassemia major patients, therefore, all thalassemics should be carefully watched for endocrine organ function such as hyperparathyroidism might occur even in the first decade of the patients with thalassemia major.
Rothmund-Thomson syndrome is a rare autosomal recessive disorder characterized by poikiloderma (skin atrophy, telangiectasia, hyper- and hypopigmentation), congenital skeletal abnormalities, short stature, premature aging, and increased risk of malignant disease. Two siblings with Rothmund-Thomson Syndrome showed the following characteristic features: severe growth failure, dystrophic nails, absent eyelashes/eyebrows, small hands, clinodactyly, microdontia and congential poikiloderma. In addition, delayed sexual development with cryptorchidism in the male and Hashimato thyroiditis in the female patient were detected. These cases are presented here because of these endocrine patterns, with the aim of drawing attention to the invisible aspects of Rothmund-Thomson syndrome.
SARS-CoV2 can induce multiple immunological and endocrinological changes. We report the case of a COVID-19 associated hyperthyroidism in a young female.
Per definition the patient – because of having given birth six weeks previously - had a postpartum thyroiditis. However thus no antibodies were detected, the thyroiditis ceased without medication after the dissolving of the virus disease and the fT3/fT3-ratio proved a destructive thyreopathy as well as there was a close time link onset of the symptoms with the novel corona virus infection we argue it to be a COVID-19 induced thyrotoxicosis.
This proves the ability of SARS-CoV-2 to alter thyroid function, therefore all COVID-19 patients should be monitored regarding endocrinological changes and TSH, fT3, fT4 should be assessed.
Papillary thyroid cancer (PTC) is the most common subtype of thyroid cancer and a highly curable malignancy . However, despite its excellent prognosis, cervical lymph node metastases (CLNMs) are present in a significant percentage of patients with papillary thyroid cancer (PTC) (upto 50% - 60%) .
Introduction: Obesity defined as increased fatty mass is progressively rising in recently, even though its affects begins to all systems in childhood and adolescence periods, the most important morbidity and mortality reason of obesity is its effects on the cardiovascular system. Researches point out endothelial dysfunction and atherosclerosis as the reason of the cardiovascular system disease in obesity. The studies conducted on childhood period related to this subject are highly limited and the results of these are also controversial. Therefore in our study the effects of obesity on endothelial functions in children and adolescents was assessed by flow mediated dilation (FMD) method. In addition to that, effects of epidemiological, biochemical, hormonal and clinical features of cases to FMD were investigated.
Material and method: A total number of 104 cases were cover in this study. Obese group (group 1) was consisted of 59 children whose body mass index (BMI) was ≥ 95th percentile and mean age was 12 ± 2.8 years old. The control group (group 2) consisted of 45 children whose body mass index (BMI) was between 25th -84th percentil and mean age was 11.4 ± 2.9 years old. The detailed history, epidemiological data and physical examination were performed. The population classified three groups according to sport activities. 97th percentile and higher values were accepted as morbid obesity. The blood pressure was measured with a mercury sphygmomanometer with utilizing the proper size cuff in compliance with the criterion used by the “National High Blood Pressure Education Program Working Group”. The complete blood count and biochemistry tests (renal and liver function tests, electrolytes, lipids, hsCRP) of the cases were analysed with biochemistry Roche Cobas Integra 800 and hormon assays of the cases (thyroid function tests, diurnal cortisol, ACTH, 17 OHP, prolactin, DHEA-S) were analysed by ECLIA method on Roche Elecsys 2010 device in the laboratory of our hospital. IR-HOMA values > 2.5 in prepuberal and > 4 in pubertal were defined as the insulin resistance. Bone ages of cases were evaluated with left hand wrist X-ray by using Greulich and Pyle Bone Age Atlas. flow mediated dilation (FMD) was used to assess the endothelial functions of all cases. The brachial artery was evaluated with SPG 12 MHz surface probes by using GE voluson ultrasound system in this method. FMD was expresses as percent (%) increase according to the basal vein dimension. 7% mean value was taken as the limit in the comparisons.
Results: The ratio of male and female was 20/39 in group 1 and 14/31 in group 2. 32.3% of the cases in group 1 and 47.6% of the cases in group 2 were prepubertal. The waist and hip circumferences ratio of the group 1 (0.86 ± 0.05) was significantly higher than group 2 (0.80 ± 0.07). While there was no difference between groups 1 and 2 in terms of the birth weight, using duration period of vitamin D and beginning time to additional nutrition, breastfeeding duration of group 1 (10.6 ± 7.8 months) was significantly shorter than group 2 (14 ± 7.4 months). BMIs of the mothers in group 1 were statistically higher than the mothers in group 2 (27.5 ± 4.8 kg/m² and 24.3 ± 3.2 kg/m² respectively. The mean of IR-HOMA was 4 ± 2.9 in group 1 and 1.9 ± 0.8 in group 2 and there was the insulin resistance in 51% of the obese cases. The dyslipidemia was diagnosed in 38.5% of the cases in group 1. The systolic and diastolic blood pressures in group 1 (117 ± 12.2 mmHg and 73.7 ± 9.4 mmHg respectively) were significantly higher than in group 2 (107.5 ± 9.1 mmHg and 68.2 ± 7.1 mmHg respectively). Hypertension was determined in 25% of the cases included in group 1. The minimum values of FMD in groups 1 and 2 were 1.01% and 3.1% respectively. The maximum values of FMD in groups 1 and 2 were 9.7% and 15% respectively. The mean values of FMD was %5 ± 2.3 in group 1 and %8.1 ± 3.5 in group 2. Compared with group 2, group 1 demonstrated significantly impaired FMD. There was no association between FMD and the birth weight, breastfeeding duration, physical exercises in two groups. A negative correlation was found between FMD and BMI (p < 0.01, r = -0.402). The correlation was determined between FMD and BMI of the mother (p = 0.017, r = -0.305) and the presence of obese individuals in the family (p = 0.021, r =-0.413). It was found that a significant negative correlation between FMD and waist-hip circumference ratio (p = 0.003, r = -0.421). When each groups were assessed in terms of biochemical and hormonal characteristics, there was low negative correlation between FMD and uric acid level and strong negative correlation between FMD and ALT level were determined in group 1.
Conclusion: In our study showed that the obesity begins in the childhood period may cause to the endothelial dysfunction. For this reason, according to our opinion, recognition prior indicators of endothelial dysfunction in early time may be helpful both to take the precautions required and to prevent cardiovascular complications in childhood and influences to the adult period.
The rising sizes of the waist and hip circumferences, positive family history for obesity and obesity of the parents were determined as the most important parameters negative affecting FMD. Unlike the literature, the association between endothelial dysfunction and GGT level the indicator of the hepatosteatosis in obese children was also found as well as FMD and ALT have also a close association independent from BMI in this study. Thus, a different point of view was formed since ALT may possibly have a predictor value in the assessment of the endothelial functions and it is also found as a highlighted risk factors for the endothelial dysfunction in this study. Because of this reason, it can be recommended that when the liver function tests carry out in obese children it does not show only hepatosteatosis but also can be used as an early indicator of the cardiovascular complications of obesity. Another important subject to be emphasize that the ALT level in the childhood period may be an early cardiovascular risk indicator in both obese and nonobese children.
SARS-CoV-2 infection is associated with thyroid disorders. It has been reported that myxedema coma (MC) can be complicated with COVID-19. COVID-19-related thyroid disorders consist of a broad spectrum of thyroid dysfunction, from thyrotoxicosis to decompensated hypothyroidism. It is possible that both primary and central thyroid disorders are induced by COVID-19 due to systemic inflammatory and immune responses. We experienced two cases in which patients with COVID-19 developed MC with central hypothyroidism. It is likely that MC affected the severity of COVID-19. It is necessary to consider the existence of MC during SARS-CoV-2 infection. We propose the potential mechanisms.
A 39-year-old woman, with a not significant past medical history, entered the Emergency Department complaining about nausea, vomiting, constipation, anorexia, deep asthenia, and diffuse muscle aches with cramps. She referred sporadic diarrhea (one episode) the day before and a worsening headache in the past three days; she also complained about polyuria and polydipsia not investigated for one year. The clinical examination was not significant, apart from the evidence of skin and mucosal dryness, tachycardia, and diffuse abdominal pain. The laboratory tests revealed hypokalemia and elevated beta-human chorionic gonadotropin (β-hCG) plasma levels. An ultrasound abdominal imaging was consistent with kidney lithiasis. Suspecting a hyperemesis gravidarum in a patient with kidney lithiasis, a rehydrating therapy was administered as long as potassium reintegration. During the hospital stay, the patient became drowsy. A haemogasanalysis revealed very high calcium values: 3,379 mmol/L (n.v. 1,120-1,320 mmol/L). Lab tests confirmed very high levels of calcium 21,1 mg/dL (n.v. 9-10,5 mg/dL), as long as increased parathormone (PTH) > 3000 pg/mL (normal values 14-65 pg/mL), and hypokalemia (3,2 mEq/L n.v. 3,50 – 4,50). Ultrasound exam of the neck revealed the presence of a left parathyroid nodule measuring 2,5 x 1,6 cm. Before having time to start an appropriate therapy, the patient died.
A mass arising from the pituitary gland commonly damages cells of the anterior pituitary gland and affects the secretion of gonadotropins and growth hormone. However, central hypothyroidism and secondary adrenal insufficiency from such damage is a rare phenomenon. Acute urinary retention as the main symptom of central hypothyroidism is also an unusual initial presentation. We report a male patient who comes with frequent urinary retention and hyponatremia at our hospital.
