Abstract
BACKGROUND Approximately 450 000 children are born with familial hypercholesterolaemia worldwide every year, yet only 2·1% of adults with familial hypercholesterolaemia were diagnosed before age 18 years via current diagnostic approaches, which are derived from observations in adults. We aimed to characterise children and adolescents with heterozygous familial hypercholesterolaemia (HeFH) and understand current approaches to the identification and management of familial hypercholesterolaemia to inform future public health strategies. METHODS For this cross-sectional study, we assessed children and adolescents younger than 18 years with a clinical or genetic diagnosis of HeFH at the time of entry into the Familial Hypercholesterolaemia Studies Collaboration (FHSC) registry between Oct 1, 2015, and Jan 31, 2021. Data in the registry were collected from 55 regional or national registries in 48 countries. Diagnoses relying on self-reported history of familial hypercholesterolaemia and suspected secondary hypercholesterolaemia were excluded from the registry; people with untreated LDL cholesterol (LDL-C) of at least 13·0 mmol/L were excluded from this study. Data were assessed overall and by WHO region, World Bank country income status, age, diagnostic criteria, and index-case status. The main outcome of this study was to assess current identification and management of children and adolescents with familial hypercholesterolaemia. FINDINGS Of 63 093 individuals in the FHSC registry, 11 848 (18·8%) were children or adolescents younger than 18 years with HeFH and were included in this study; 5756 (50·2%) of 11 476 included individuals were female and 5720 (49·8%) were male. Sex data were missing for 372 (3·1%) of 11 848 individuals. Median age at registry entry was 9·6 years (IQR 5·8-13·2). 10 099 (89·9%) of 11 235 included individuals had a final genetically confirmed diagnosis of familial hypercholesterolaemia and 1136 (10·1%) had a clinical diagnosis. Genetically confirmed diagnosis data or clinical diagnosis data were missing for 613 (5·2%) of 11 848 individuals. Genetic diagnosis was more common in children and adolescents from high-income countries (9427 [92·4%] of 10 202) than in children and adolescents from non-high-income countries (199 [48·0%] of 415). 3414 (31·6%) of 10 804 children or adolescents were index cases. Familial-hypercholesterolaemia-related physical signs, cardiovascular risk factors, and cardiovascular disease were uncommon, but were more common in non-high-income countries. 7557 (72·4%) of 10 428 included children or adolescents were not taking lipid-lowering medication (LLM) and had a median LDL-C of 5·00 mmol/L (IQR 4·05-6·08). Compared with genetic diagnosis, the use of unadapted clinical criteria intended for use in adults and reliant on more extreme phenotypes could result in 50-75% of children and adolescents with familial hypercholesterolaemia not being identified. INTERPRETATION Clinical characteristics observed in adults with familial hypercholesterolaemia are uncommon in children and adolescents with familial hypercholesterolaemia, hence detection in this age group relies on measurement of LDL-C and genetic confirmation. Where genetic testing is unavailable, increased availability and use of LDL-C measurements in the first few years of life could help reduce the current gap between prevalence and detection, enabling increased use of combination LLM to reach recommended LDL-C targets early in life.

Low circulating PCSK9 levels in LPL homozygous children with chylomicronemia syndrome in a syrian refugee family in Lebanon. Front Genet 2022; 13:961028.

Abstract
Familial chylomicronemia syndrome is a rare autosomal recessive disorder of lipoprotein metabolism characterized by the presence of chylomicrons in fasting plasma and an important increase in plasma triglycerides (TG) levels that can exceed 22.58 mmol/l. The disease is associated with recurrent episodes of abdominal pain and pancreatitis, eruptive cutaneous xanthomatosis, lipemia retinalis, and hepatosplenomegaly. A consanguineous Syrian family who migrated to Lebanon was referred to our laboratory after perceiving familial chylomicronemia syndrome in two children. The LPL and PCSK9 genes were sequenced and plasma PCSK9 levels were measured. Sanger sequencing of the LPL gene revealed the presence of the p.(Val227Phe) pathogenic variant in exon 5 at the homozygous state in the two affected children, and at the heterozygous state in the other recruited family members. Interestingly, PCSK9 levels in homozygous carriers of the p.(Val227Phe) were ≈50% lower than those in heterozygous carriers of the variant (p-value = 0.13) and ranged between the 5th and the 7.5th percentile of PCSK9 levels in a sample of Lebanese children of approximately the same age group. Moreover, this is the first reported case of individuals carrying simultaneously an LPL pathogenic variant and PCSK9 variants, the L10 and L11 leucine insertion, which can lower and raise low-density lipoprotein cholesterol (LDL-C) levels respectively. TG levels fluctuated concomitantly between the two children, were especially high following the migration from a country to another, and were reduced under a low-fat diet. This case is crucial to raise public awareness on the risks of consanguineous marriages to decrease the emergence of inherited autosomal recessive diseases. It also highlights the importance of the early diagnosis and management of these diseases to prevent serious complications, such as recurrent pancreatitis in the case of familial hyperchylomicronemia.

BACKGROUND The European Atherosclerosis Society Familial Hypercholesterolaemia Studies Collaboration (FHSC) global registry provides a platform for the global surveillance of familial hypercholesterolaemia through harmonisation and pooling of multinational data. In this study, we aimed to characterise the adult population with heterozygous familial hypercholesterolaemia and described how it is detected and managed globally. METHODS Using FHSC global registry data, we did a cross-sectional assessment of adults (aged 18 years or older) with a clinical or genetic diagnosis of probable or definite heterozygous familial hypercholesterolaemia at the time they were entered into the registries. Data were assessed overall and by WHO regions, sex, and index versus non-index cases. FINDINGS Of the 61 612 individuals in the registry, 42 167 adults (21 999 [53·6%] women) from 56 countries were included in the study. Of these, 31 798 (75·4%) were diagnosed with the Dutch Lipid Clinic Network criteria, and 35 490 (84·2%) were from the WHO region of Europe. Median age of participants at entry in the registry was 46·2 years (IQR 34·3-58·0); median age at diagnosis of familial hypercholesterolaemia was 44·4 years (32·5-56·5), with 40·2% of participants younger than 40 years when diagnosed. Prevalence of cardiovascular risk factors increased progressively with age and varied by WHO region. Prevalence of coronary disease was 17·4% (2·1% for stroke and 5·2% for peripheral artery disease), increasing with concentrations of untreated LDL cholesterol, and was about two times lower in women than in men. Among patients receiving lipid-lowering medications, 16 803 (81·1%) were receiving statins and 3691 (21·2%) were on combination therapy, with greater use of more potent lipid-lowering medication in men than in women. Median LDL cholesterol was 5·43 mmol/L (IQR 4·32-6·72) among patients not taking lipid-lowering medications and 4·23 mmol/L (3·20-5·66) among those taking them. Among patients taking lipid-lowering medications, 2·7% had LDL cholesterol lower than 1·8 mmol/L; the use of combination therapy, particularly with three drugs and with proprotein convertase subtilisin-kexin type 9 inhibitors, was associated with a higher proportion and greater odds of having LDL cholesterol lower than 1·8 mmol/L. Compared with index cases, patients who were non-index cases were younger, with lower LDL cholesterol and lower prevalence of cardiovascular risk factors and cardiovascular diseases (all p<0·001). INTERPRETATION Familial hypercholesterolaemia is diagnosed late. Guideline-recommended LDL cholesterol concentrations are infrequently achieved with single-drug therapy. Cardiovascular risk factors and presence of coronary disease were lower among non-index cases, who were diagnosed earlier. Earlier detection and greater use of combination therapies are required to reduce the global burden of familial hypercholesterolaemia.

Abstract
Familial hypobetalipoproteinemia (FHBL) is a codominant genetic disorder characterized by reduced plasma levels of low-density lipoprotein cholesterol and apolipoprotein B. To our knowledge, no study on FHBL in Lebanon and the Middle East region has been reported. Therefore, we conducted genetic studies in unrelated families and probands of Lebanese origin presenting with FHBL, in order to identify the causes of this disease. We found that 71% of the recruited probands and their affected relatives were heterozygous for the p.(Arg490Trp) variant in the APOB gene. Haplotype analysis showed that these patients presented the same mutant haplotype. Moreover, there was a decrease in plasma levels of PCSK9 in affected individuals compared to the non-affected and a significant positive correlation between circulating PCSK9 and ApoB levels in all studied probands and their family members. Some of the p.(Arg490Trp) carriers suffered from diabetes, hepatic steatosis or neurological problems. In conclusion, the p.(Arg490Trp) pathogenic variant seems a cause of FHBL in patients from Lebanese origin, accounting for approximately 70% of the probands with FHBL presumably as a result of a founder mutation in Lebanon. This study is crucial to guide the early diagnosis, management and prevention of the associated complications of this disease.

Abstract
Given that the complications of type 2 diabetes can start at an early stage, early detection and appropriate management of prediabetes are essential. We aimed to develop an expert opinion on prediabetes in Lebanon to pave the way for national guidelines tailored for the Lebanese population in the near future. A panel of seven diabetes experts conducted a thorough literature review and discussed their opinions and experiences before coming up with a set of preliminary recommendations for the detection and management of prediabetes in Lebanon. Lebanese physicians employ multiple tests for the diagnosis of prediabetes and no national cut-off values exist. The panel agreed that prediabetes screening should be focused on patients exceeding 45 years of age with otherwise no risk factors and on adults with risk factors. The panel reached that fasting plasma glucose (FPG) and HbA1c should be used for prediabetes diagnosis in Lebanon. FPG values of 100-125 mg/dL or HbA1c values of 5.7%-6.4% were agreed upon as indicative of prediabetes. For the management of prediabetes, a three-step approach constituting lifestyle modifications, pharmacological treatment and bariatric surgery is recommended. There should be more focus on research on prediabetes in Lebanon. This preliminary report will be further discussed with the Lebanese Society of Endocrinology, Diabetes and Lipids in 2021 in order to come up with the first Lebanese national guidelines for the detection and management of prediabetes in Lebanon.

Abstract
BACKGROUND Cardiovascular disease (CVD), the main macro vascular complication of type 2 diabetes (T2D), increases the risk of death significantly in patients with T2D. INTRODUCTION Most of the patients with T2D do not have obvious CVD symptoms. Due to the paucity of data, CVD screening in asymptomatic patients with T2D remains highly controversial. METHODS This has driven a panel of experts to establish a novel consensus on how to approach patients with T2D at high CVD risk. The panel formulated a stepwise algorithm by which patients with T2D undergo initial risk stratification into low, intermediate and high risk using the ASCVD calculator. In patients with intermediate risk, coronary artery calcium measurement is used to further stratify those patients into new low and high-risk categories. RESULTS AND CONCLUSION The panel recommends using standard diabetes care in low risk patients and using SGLT2 inhibitors and GLP1 agonists with cardio protective effect, on top of standard care, in high risk individuals.

Abstract
BACKGROUND Prolactinomas are the commonest functional tumors of the pituitary gland. There are still controversies regarding medical therapy in specific clinical situations. Patients may be managed by different specialists in the Middle East and North Africa (MENA) region and no data exist on patterns of clinical management. OBJECTIVES To ascertain the diagnostic and therapeutic approaches to prolactinomas among relevant professionals from the MENA region. METHODS An online survey of a large sample of physicians was conducted. The questionnaire covered various aspects of diagnosis and treatment of prolactinomas. 468 respondents were included; 36 % were endocrinologists; 49 % worked in public facilities and 81 % graduated more than 10 years. 40 and 30 % would have seen 1-5 and more than 5 suspected or confirmed prolactinomas over a 6 months period, respectively. RESULTS Regarding the diagnosis, 30 % of the respondents considered that prolactin levels <100 ng/ml exclude the presence of a prolactinoma. 21 % of respondents considered prolactin levels >250 ng/ml compatible with macroprolactinomas only, whereas others accepted this to be compatible also with microprolactinomas, macroprolactinaemia and drug-induced hyperprolactinemia (50, 42 and 36 % respectively). 71 % of respondents favored the screening for macroprolactin in asymptomatic individuals with hyperprolactinemia. Regarding the treatment, 84 % of respondents would treat microprolactinomas even in the absence of symptoms whereas 72 % of the respondents would treat microprolactinomas only if symptoms exist. 60 and 49 % of the respondents chose cabergoline as the drug of choice to treat macroprolactinomas and microprolactinomas respectively. Similar proportions had no preference of either cabergoline or bromocriptine as the best treatment for macroprolactinoma (27 %) and microprolactinomas (32 %). 46 and 75 % of respondents favored treatment withdrawal 2-3 years after prolactin normalization in patients with macroprolactinomas and microprolactinomas, respectively whereas 10 % of respondents withdraw treatment after menopause in either case. 94 % of respondents considered medical therapy as the primary treatment for microprolactinomas. In case of pregnancy, 49 % considered bromocriptine as the drug of choice for women who wish to become pregnant. 65 and 38 % of respondents advocated discontinuation of treatment with dopamine agonists in patients with microprolactinomas and macroprolactinomas, respectively. Finally, 48 % would allow breast-feeding without restriction, 28 % would restrict it to patients with microprolactinomas and 25 % would not recommend it for women with prolactinomas. CONCLUSIONS This is the first study of the clinical management of prolactinomas in the MENA region. Some of the practices are not in line with the latest Endocrine and Pituitary Societies guidelines. These warrant further discussions of contemporary guidelines in regional forums.

Abstract
The increase in the cardiovascular disease (CVD)-associated mortality rate in the Middle East (ME) is among the highest in the world. The aim of this article is to review the current prevalence of dyslipidaemia and known gaps in its management in the ME region, and to propose initiatives to address the burden of dyslipidaemia. Published literature on the epidemiology of dyslipidaemia in the ME region was presented and discussed at an expert meeting that provided the basis of this review article. The high prevalence of metabolic syndrome, diabetes, familial hypercholesterolaemia (FH) and consanguineous marriages, in the ME region, results in a pattern of dyslipidaemia (low high-density lipoprotein cholesterol and high triglycerides) that is different from many other regions of the world. Early prevention and control of dyslipidaemia is of paramount importance to reduce the risk of developing CVD. Education of the public and healthcare professionals and developing preventive programs, FH registries and regional guidelines on dyslipidaemia are the keys to dyslipidaemia management in the ME region.

Abstract
BACKGROUND Cardiovascular disease is the leading cause of death and disability worldwide. Therefore, as part of the Dyslipidemia International Study (DYSIS), we have analyzed the prevalence of lipid abnormalities and risk factors for dyslipidemia in statin-treated patients in Lebanon and Jordan. METHODS This cross-sectional, multicenter study enrolled 617 patients at 13 hospitals in Lebanon and Jordan. Patients were at least 45 years old and had been treated with statins for at least 3 months. Multivariate logistic regression analysis was used to determine patient characteristics contributing to dyslipidemia during statin therapy. RESULTS Our findings indicated that 55.9% of statin-treated patients (mean age 60.3 years, 47% female) in Lebanon and Jordan did not achieve goal levels for low-density lipoprotein cholesterol which were dependent on Systematic Coronary Risk Evaluation (SCORE) risk, and 70% of patients (76% men and 63.3% of women) were at very high cardiovascular risk. Low-density lipoprotein cholesterol goals were not achieved in 67.2% of those with very high cardiovascular risk. The most commonly prescribed statin was atorvastatin (44.6%), followed by simvastatin (27.7%), rosuvastatin (21.2%), fluvastatin (3.3%), pravastatin (3%), and lovastatin (0.2%). Approximately half of the population was treated with a statin dose potency of 4, equaling 40 mg of simvastatin. In Lebanon and Jordan, the strongest independent associations with low-density lipoprotein cholesterol not at goal were current smoking (odds ratio [OR] 1.96; 95% confidence [CI] 1.25-3.08), diabetes mellitus (OR 2.53; 95% CI 1.70-3.77), and ischemic heart disease (OR 2.26; 95% CI 1.45-3.53), while alcohol consumption was associated with reduced risk (OR 0.12; 95% CI 0.03-0.57). CONCLUSION We observed that many patients in Lebanon and Jordan experienced persistent dyslipidemia during statin treatment, supporting the notion that novel lipid-lowering strategies need to be developed. Also, social programs aimed at combating the extremely high rates of tobacco use and obesity in Lebanon and Jordan are critical for combating cardiovascular disease in these countries.

Abstract
There is now a wealth of experimental evidence indicating that the deficit in endogenous estrogen facilitates the onset of inflammation that can be antagonized by estrogen replacement therapy. This work investigated the role of estrogen in the control of intestinal inflammation in a panel of colitis models, focusing on the morphological changes, the activity of mast cells, the expression of cytokines (IL-1beta, IL-6, and TNF-alpha), fibronectin and reactive oxygen species. Two hundred adult male rats were divided into 4 groups: colitis was induced in Group I and Group II but only the latter was treated with estrogen; Group III received estrogen only, and Group IV saline. Colitis was induced in 4 models using: iodoacetamide; iodoacetamide + enteropathogenic E. coli; 2, 4, 6-Trinitrobenzene sulfonic acid; and dextran sulfate sodium salt. Macroscopic and microscopic evaluations of abdominal structures as well as molecular analysis were made on days 7, 14, 28 and 56. There was a significant improvement in the health condition of the estrogen-treated rats: the inflammation scores were reduced by at least 10-15%, the number of mast cells in the colon decreased by 30%, fibronectin expression was only 50% and reactive oxygen species decreased by 30%. In addition, there was a significant decrease in TNF-alpha, IL-6 and IL-1beta expression by about 25%. In conclusion, there was an improvement in the inflammatory status in all estrogen-treated groups through the duration of the experiment at all-time points. In addition, there was less tissue necrosis as depicted by less fibronectin and a marked antioxidant effect.

Abstract
The prevalence of painful diabetic peripheral neuropathy (DPN) was evaluated in type 1 or type 2 diabetes mellitus patients (n = 4097) attending outpatient clinics across the Middle East. Overall, 53.7% of 3989 patients with DN4 data met the criteria for painful DPN (Douleur Neuropathique-4 [DN4] scores ≥ 4). Significant predictors of painful DPN included long history (≥ 10 years) of diabetes (odds ratio [OR] 2.43), age ≥ 65 years (OR 2.13), age 50 - 64 years (OR 1.75), presence of type 1 versus type 2 diabetes (OR 1.59), body mass index > 30 kg/m(2) (OR 1.35) and female gender (OR 1.27). Living in one of the Gulf States was associated with the lowest odds of having painful DPN (OR 0.44). The odds of painful DPN were highest among patients with peripheral vascular disease (OR 4.98), diabetic retinopathy (OR 3.90) and diabetic nephropathy (OR 3.23). Because of the high prevalence and associated suffering, disability and economic burden of painful DPN, it is important that diabetic patients are periodically screened, using a simple instrument such as the DN4, and receive appropriate treatment if symptoms develop.

Abstract
Graves' ophthalmopathy is a debilitating disease impairing the quality of life of affected individuals. The management of moderate-to-severe active Graves' ophthalmopathy is a major therapeutic challenge, and the treatment outcome is often unsatisfactory. We have carried out a retrospective study to assess the efficacy of combined orbital irradiation and systemic corticosteroids. Ten patients were included; all patients had received 20 Grays to the retrobulbar tissues in ten fractions, and oral or intravenous glucocorticoids. The main therapeutic outcome measures were the criteria of Donaldson and co-workers and a self-assessment evaluation. The quality of life outcome was also evaluated by the GO-QOL (Graves' ophthalmopathy quality of life) questionnaire. Seven patients (70%) demonstrated improvement in ocular parameters; the response was excellent in three cases, good in three cases and fair in one case. Three patients showed no response to the treatment. The self-assessment evaluation showed that 75% of patients were satisfied with the results of the treatment. Proptosis was the most responsive sign to radiation and steroids. A duration of the eye disease of more than 18 months was associated with less improvement and a higher failure of the treatment. Concerning the quality of life, the score for visual fonctionning was 882 +/- 18.2 after treatment, while the score for appearance was 63.3 +/- 23.3. In conclusion, a combination of orbital irradiation and systemic steroids is associated with 70% of favorable responses, but the quality of life is not restored in the same proportions and remains impaired after treatment.

Abstract
BACKGROUND The predictors of intra-operative PTH (IOPTH) decline during minimally invasive parathyroidectomy (MIP) for primary hyperparathyroidism have been but poorly studied. MATERIALS AND METHODS This retrospective study included 108 patients who underwent MIP for a single adenoma. Serum calcium and phosphorus were measured before surgery and 1 day post-operatively. IOPTH was measured before (intra-operative preincision or PTHt0) and 10 min after removal of the adenoma (PTHt10). The Modification of Diet in Renal Disease (MDRD) equation was used to estimate the glomerular filtration rate. The weight of the adenoma was assessed in all the subjects. RESULTS The sex ratio female/male was 5.37 with a mean age of 57.3 yr. The mean pre- and postoperative values were for calcium 2.80 and 2.19 mmol/l, respectively (p<0.0001) and for phosphorus 0.90 and 1.16 mmol/l, respectively (p<0.0001). The PTH dropped from a mean value of 184.8 to 50.8 pg/ml 10 min after adenoma resection with a mean drop of 69.7%. Thirteen patients (12%) did not achieve a PTH fall of more than 50%. In a bivariate analysis, age, an MDRD<60 ml/min and weight of adenoma were inversely associated with IOPTH fall (p=0.009, p=0.004, and p<0.001, respectively) while gender, body mass index, hypertension, diabetes, pre-operative phosphorus and calcium had no significant effects. In the multivariate analysis, age, weight of adenoma, and MDRD were still independent negative predictors of the IOPTH fall (p=0.01, p=0.018, and p<0.001, respectively). CONCLUSION Our results suggest that during MIP the presence of a parathyroid adenoma with a high weight, in an elderly subject or in a subject with altered renal function, will result in a lesser degree of IOPTH fall.

Abstract
OBJECTIVE The relationships between adipocytokines, sex steroids and the GH/IGF-I axis is poorly studied and subject to controversy in healthy elderly male subjects. We investigated the association between both adiponectin and leptin, and the metabolic syndrome (MetS), lipid parameters, insulin sensitivity, sex steroids and IGF-I in healthy non-diabetic Lebanese men. DESIGN AND METHODS In this cross-sectional study, a total of 153 healthy non-diabetic men aged 50 and above (mean age 59.3 +/- 7 years) had a detailed clinical and biological evaluation. Subjects were classified according to the National Cholesterol Education Program criteria of the MetS. Insulin sensitivity was determined by the Quantitative Insulin Sensitivity Check Index (QUICKI). RESULTS Subjects with the MetS had lower adiponectin and higher leptin levels (P < 0.0001 for both variables) compared with individuals without the MetS. Adiponectin was significantly correlated with waist size, triglycerides, high-density lipoprotein (HDL) cholesterol and QUICKI (r = -0.33, -0.26, 0.45 and 0.36 respectively, P < 0.0001 for all variables). The relation between adiponectin and HDL cholesterol, triglycerides and QUICKI remained significant after adjustment for age and body mass index (BMI). Also, leptin was strongly correlated with waist size and QUICKI (r = 0.63 and -0.63 respectively, P < 0.001 for both variables). However, its relation to the lipid profile was weak (for cholesterol r = 0.16, P < 0.05; for triglycerides r = 0.17, P < 0.05) and disappeared after adjustment for BMI. Adiponectin was positively correlated with sex hormone-binding globulin (SHBG) (r = 0.39, P < 0.001) and inversely correlated with free-androgen index (r = -0.24, P < 0.01), estradiol and dehydroepiandrosterone sulfate (r = -0.165, P < 0.05; r = -0.21, P < 0.01 respectively). This difference remained significant for SHBG after adjustment for age and BMI (r = 0.20, P < 0.005). Finally, leptin was inversely correlated with total testosterone and SHBG (r = -0.44, P < 0.001; r = -0.30, P < 0.001 respectively); the relation with testosterone remained significant after adjustment for BMI. No significant relationship of either adiponectin or leptin with GH or IGF-I values was observed. In a stepwise multiple regression analysis, the independent predictors of adiponectin were HDL cholesterol, QUICKI, age and BMI (P < 0.0001, P = 0.005, P = 0.002 and P = 0.047 respectively) while for leptin, it was QUICKI, waist size and testosterone (P < 0.0001, P < 0.0001 and P = 0.004 respectively). The adjusted R2 values were 0.34 and 0.55. CONCLUSION Our results show that in a healthy elderly male population, both adiponectin and leptin are related to insulin sensitivity, independent of age and BMI. While adiponectin is independently related to triglycerides and HDL cholesterol, the weak relationship of leptin to the lipid profile is completely mediated by BMI. In addition, and more interestingly, both adipocytokines are strongly associated with sex steroids. We speculate that SHBG is regulated by adiponectin and that there is an inhibitory effect of testosterone on the adiponectin gene. Further studies are needed to fully elucidate these relationships.

Abstract
OBJECTIVE The relationship between osteoprotegerin (OPG) and lipid profile, insulin sensitivity, adipocytokines and sex steroids has been poorly studied and subject to controversy. The purpose of this study was to look at the correlates of OPG in an elderly male population. DESIGN One hundred and fifty-one nondiabetic, elderly Lebanese men (age range 50-83) were recruited in this cross-sectional study based on voluntary enrolment. MEASUREMENTS In all the subjects, serum OPG levels were measured and related to clinical parameters (age, waist, body mass index (BMI), systolic and diastolic blood pressure), as well as to metabolic and hormonal parameters. The following fasting laboratory measurements were performed: plasma glucose and insulin levels, total cholesterol, triglycerides and HDL cholesterol, adiponectin, leptin, as well as sex steroids (testosterone, SHBG, free androgen index, ooestradiol, DHEAS), GH and IGF-1. QUICKI index was calculated as a measure of insulin sensitivity. RESULTS OPG levels were significantly correlated with age (r = 0.28, P < 0.0001) but not with BMI, waist, systolic or diastolic blood pressure. There was a trend towards higher OPG levels in subjects without, compared to subjects with the metabolic syndrome (3.58 +/- 1.28 vs. 3.26 +/- 1.04 pmol/l, P = 0.09). OPG was negatively correlated with fasting glucose and triglyceride levels (r = -0.18, P = 0.031 and r = -0.19, P = 0.02, respectively) and positively correlated with the QUICKI index (r = 0.17, P = 0.033), HDL cholesterol (r = 0.21, P = 0.009) and adiponectin levels (r = 0.27, P = 0.001). No significant correlations were reported with total or LDL cholesterol levels and with leptin levels. After adjustment for age, OPG is still correlated with triglycerides (r = -0.19, P = 0.02), glucose (r = -0.21, P = 0.011) and adiponectin (r = 0.19, P = 0.02). Finally, OPG was positively associated with SHBG (r = 0.31, P < 0.001) and negatively associated with free androgen index (r =-0.346, P < 0.001); both correlations persisted after adjustment for age (r = 0.21, P = 0.009 and r = -0.23, P = 0.005, respectively). No significant correlation was found between OPG and oestradiol levels while a weak negative correlation was demonstrated with DHEAS (r = -0.18, P = 0.025). Also, no significant correlation was found between OPG and GH or IGF-1 values. In a multiple regression analysis with a stepwise model, the main determinants of OPG were free androgen index and adiponectin (P < 0.0001 and P = 0.015, respectively). CONCLUSION Our results show that circulating OPG levels are favourably associated with some components of the metabolic syndrome. Also, for the first time, an association between OPG and adiponectin is described. Finally, the negative correlation we found between OPG and free androgen index may suggest a potential role of OPG in the increase in cardiovascular disease related to ageing and sex steroid deficiency.

Abstract
Development of vocal fold paralysis in the presence of thyroid disease is strongly indicative of thyroid cancer, and requires surgical exploration. At the same time, vocal fold paralysis does not relieve the surgeon of his obligation to identify and preserve the recurrent laryngeal nerves, since the cause of the paralysis may be a benign disease, with a fair chance of functional recovery after surgery. We hereby report a case of recurrent laryngeal nerve palsy secondary to a multinodular goitre.

Abstract
TSH receptor antibodies (TRAb) was performed by binding assay in seventy-seven patients (47 with Graves disease, 32 with other thyroid abnormalities). The sensitivity and specificity of our assay were respectively 81% and 96.5%. These results were similar to the results found in medical literature. The association of ophthalmopathy with Graves disease does not increase the sensitivity of the test. In this study we conclude that TRAb assay is of great interest in confirming the diagnosis and in the following of Graves disease.

Abstract
The routine use of automated techniques to measure serum calcium levels have made disease states of the parathyroid gland a common endocrinologic problem. Because of the low sensitivity and specificity of early radiologic techniques to identify enlarged parathyroid glands, and because skilled endocrine surgeons report success rates of > 95% in identifying abnormal parathyroid glands, historically most parathyroid glands surgery consisted in a large cervicotomy under general anesthesia without preoperative localization. However, the development of sophisticated imaging techniques has now made it possible to identify the abnormal gland in a significant number of patients, leading some surgeons to choose unilateral neck exploration under local anesthesia for primary hyperparathyroidism. The success of the procedure is ascertained by measuring PTH peroperatively. We report the first two Lebanese patients, presenting with a solitary parathyroid adenoma, who underwent this easy, safe and cost-effective surgical technique.

Abstract
The treatment of congenital adrenal hyperplasia (hypertensive forms) is based, as in the other forms of congenital adrenal hyperplasia, on corticosteroid therapy. The choice of drug, dosage, precocity, clinical and biological surveillance, are analysed in turn. The results on pubertal development, adult size, gonad development in the 11-betahydroxylase deficit type, are considered in the light of recent studies. The treatment of the 17-alpha-hydroxylase type is also based on the inhibition of glucocorticoid secretion. Results are satisfactory in the few cases published.

Abstract
We report severe 17 alpha-hydroxylase deficiency in a 17 year-old black girl with 46,XX genotype. The diagnosis was suspected because of primary amenorrhoea, absence of sexual maturation, hypertension and hypokalaemia with renal potassium wasting. Endocrine investigation revealed low basal levels of all steroid hormones which require 17 alpha-hydroxylation for biosynthesis (i.e. glucocorticoids, androgens and oestrogens). No increase in their basal levels was seen following adrenal stimulation, indicating a severe block. Plasma concentrations of ACTH, FSH and LH were elevated as were progesterone, 11-deoxycorticosterone and corticosterone. Plasma renin activity was suppressed and aldosterone levels were very low. After 4 months of glucocorticoid replacement therapy, aldosterone was still low, even though the suppression was otherwise effective. Our case is unusual because bilateral streak gonads and impaired development of Müllerian ducts derivatives were also present. To our knowledge, a similar case has never been reported before.

Abstract
Some patients are clinically euthyroid despite high thyroid hormones levels associated with detectable but not elevated serum TSH. These patients are considered as being resistant to thyroid hormones. The resistance may be severe or partial and in most cases seems to be autosomal dominant; it affects some tissues more than others, thus giving rise to a variety of clinical symptoms. In a few patients with high TSH levels extensive studies have failed to provide evidence of pituitary tumour of resistance to thyroid hormones; the cause of TSH hypersecretion in such cases remains uncertain. Several factors (non specific serum proteins, cross-reactivity circulating antibodies) may result in falsely high T3, T4 and TSH values on radioimmune assays and must be carefully investigated in the presence of unexpectedly high serum TSH levels.

Abstract
Release of thyroxine and triiodothyronine from the thyroid gland is stimulated by the pituitary hormone thyrotropin, or thyroid-stimulating hormone (TSH). TSH secretion in turn is regulated by control mechanisms, which include a negative feedback effect of the thyroid hormones themselves and the actions of the hypothalamic peptide TRH and of several central neurotransmitters. Hyperthyroidism secondary to excessive TSH secretion is a rare entity. In most cases TSH hypersecretion results from an adenoma of the pituitary gland and may then be associated with increased prolactin or growth hormone production. It should be emphasized that most patients with pituitary adenoma have high serum levels of alpha TSH subunit and undetectable beta TSH subunit.

Abstract
The authors draw attention to the fact that the decrease in 17-hydroxycorticosteroids and 17-ketosteroids observed in patients under meprobamate treatment is probably due to chemical interference with assay methods, since normal response to metyrapone indicates that the adrenal function is unimpaired. The asthenia usually reported by these patients is due to depression and should not be blamed on deficiency of the adrenal cortex.

They outline the three abnormalities which may lead to a male pseudohermaphroditism: disorders of testicular differentiation, defects of testicular function and androgen insensitiveness at the target areas. They consider the diagnostic steps and the therapeutic management especially in relation to the choice of the sex and the risk of gonadoblastoma.

Three cases of hypothalamic panhypopituitarism in male adults are reported. Two of them, without antidiuretic hormone deficiency, succeeded to a closed head injury. The third one was associated with impaired posterior pituitary function and presumably was of idiopathic origin, since radiological and ophthalmological investigations gave normal results, although the disease seemed to have begun some 20 years before.

Abstract
The apoproteins are the constitutive peptides of the plasma lipoproteins. The most widely employed nomenclature is that based on the family concept of constitutive polypeptides. The apoproteins are synthetized in the liver and/or in the intestine. During the lipolysis, apoprotein transfers and/or exchanges are observed. The apoproteins play a major role in the structure of the macromolecular lipid-protein complexes, and in the activity of several enzymes involved in the lipoprotein catabolism. An expanding information on apoprotein metabolism will allow a better comprehension of the hyperlipidemia pathogenesis.

Abstract
A complete endocrinological exploration was performed in a 23 year old male patient who presented clinical signs of an acquired panhypopituitarism which appeared two months after a severe head trauma, in order to determine whether the deficit lay in the hypothalamus or in the pituitary. TSH had normal basal levels, but presented a delayed rise after TRH administration. PRL rose normally after TRH administration, but presented a blunted response to both metoclopramide and insulin tolerance test. Cortisol rose significatively after lysine vasopressin, but failed to rise during insulin hypoglycaemia. These results are consistent with a hypothalamic defect. Extensive endocrinological data are often lacking in the few similar cases reported in the literature. Prl and TSH were usually found to have normal basal levels while other pituitary hormones were profoundly lowered. This was interpretated as a pituitary defect with some intact areas of the anterior lobe. However, this may also suggest a hypothalamic defect which could have been assessed by mor discriminative tests.

Abstract
The various elements derived from the neural crest are reviewed and their relationship with the APUD system discussed. The resulting physiopathological consequences imply that there is a common embryonic origin for cells which appear to be unrelated. A classification of the various pathological affections involving these cells, is proposed.

Abstract
The authors review various of the derivatives of the neural crest, consider their relationship with the APUD System, and deduce the physiopathological consequences applicable to these cells, whose only similarity lies in their common embryologic origin. They propose a system of classification of interrelated pathological conditions that these cells may show, an detail clinical information as well as the mode of genetic transmission of the principal neurocristopathic syndroms.

Abstract
Endocrine features associated with the primary empty sella turcica syndrom are rare; they are usually related to a pituitary microadenoma and more rarely to an idiopathic panhypop ituitarism. A pituitary dwarfism with an idiopathic panhypopituitarism of hypothalamic origin, associated with an "empty" sella turcica containing functional and stimulable pituitary tissue, is reported in a 27 year old male Moraccan.
