Mapping the Locations of Medical Specialists in the Ministry of Health's Hospitals in Malaysia by Specialty, Subspecialty and Area of Interest.

Mapping the distribution of medical specialists in the Ministry of Health (MOH) Malaysia facilities is expected to be more complex as the demand for specialty and subspecialty services increases in the future. A more robust and definitive gap analysis is needed to facilitate planning and resource allocation. The Medical Development Division developed a master list of framework of specialties, subspecialties and areas of interest, and Specialist Database Module in the Medical Programme Information System (MPIS) as tools to facilitate mapping of services. Relational database of specialists' location, facilities, workload, population profile and other relevant parameters were developed to provide data visualisation in specific dashboard. Needs versus supply ratio is proposed as one of parameters to visualise specialised medical services distribution by geographical localities.

Pitfalls in the Diagnosis of Primary Hyperparathyroidism in a Sudanese Adolescent Boy; a case disguised as rickets.

BACKGROUND: Juvenile primary hyperparathyroidism (PHPT) is a rare endocrine disease. Its diagnosis might be masked by clinical, biochemical, and radiological features of rickets. CASE PRESENTATION: A 12-year-old Sudanese boy presented with progressive lower limbs deformity and difficulty in walking for six months. It was associated with fatigability, poor appetite, and generalized bone pain. On examination, he was thin, disproportionately short and pubertal, and had bilateral genu valgum deformity. X-rays showed osteopenia and signs of rickets. Biochemical workup revealed mildly elevated serum calcium, low phosphate, high alkaline phosphatase, and high parathyroid hormone with low 25-hydroxy vitamin D3. Celiac screening, liver function test and renal profile were normal. Serum calcium rose dramatically after vitamin D therapy. Genetic testing was negative for CYP2R1 and MEN1 genes. Ultrasound neck showed left inferior parathyroid adenoma which was surgically excised. Histopathology confirmed the diagnosis of parathyroid adenoma. Postoperatively, he had hypocalcemia which was treated with calcium and alfacalcidol. Corrective surgery is planned for the genu valgum deformity which markedly improved after parathyroidectomy. CONCLUSION: Although PHPT is extremely rare in the young population, it should be considered in patients with rickets and elevated serum calcium at baseline or after initiating vitamin D therapy.

Autologous Cardiac Stem Cell Injection in Patients with Hypoplastic Left Heart Syndrome (CHILD Study).

Mortality in infants with hypoplastic left heart syndrome (HLHS) is strongly correlated with right ventricle (RV) dysfunction. Cell therapy has demonstrated potential improvements of RV dysfunction in animal models related to HLHS, and neonatal human derived c-kit+ cardiac-derived progenitor cells (CPCs) show superior efficacy when compared to adult human cardiac-derived CPCs (aCPCs). Neonatal CPCs (nCPCs) have yet to be investigated in humans. The CHILD trial (Autologous Cardiac Stem Cell Injection in Patients with Hypoplastic Left Heart Syndrome) is a Phase I/II trial aimed at investigating intramyocardial administration of autologous nCPCs in HLHS infants by assessing the feasibility, safety, and potential efficacy of CPC therapy. Using an open-label, multicenter design, CHILD investigates nCPC safety and feasibility in the first enrollment group (Group A/Phase I). In the second enrollment group, CHILD uses a randomized, double-blinded, multicenter design (Group B/Phase II), to assess nCPC efficacy based on RV functional and structural characteristics. The study plans to enroll 32 patients across 4 institutions: Group A will enroll 10 patients, and Group B will enroll 22 patients. CHILD will provide important insights into the therapeutic potential of nCPCs in patients with HLHS.Clinical Trial Registration https://clinicaltrials.gov/ct2/home NCT03406884, First posted January 23, 2018.

Timed Up and Go and Five Times Sit to Stand Test among community ambulant, overweight, obese Saudi elderly population.

OBJECTIVE: To investigate the effect of Timed Up and Go category on the Five Times Sit to Stand Test, and to determine the role of recreational status on Timed Up and Go rating. METHODS: The descriptive, cross-sectional study was conducted between October 2018 and April 2019 at the College of Medical Rehabilitation Sciences, Taibah University, Madina, Saudi Arabia, and comprised community-ambulant retired overweight or obese subjects of either gender aged 60-69 years. Timed Up and Go, Five Times Sit to Stand Test and Single-Leg Stance Test were used to measure basic mobility, transitional skills and static balance respectively. Data was analysed using SPSS 23. RESULTS: Of the 150 subjects, 108(72%) were males and 42(28%) were females. The overall mean age was 63.1}2.5 years and the mean body mass index was 29.6}3.8 kg/m2. There were 46(31.5%) subjects who were freely mobile, 60(41.1%) who were mostly independent and 40(27.4%) who had variable mobility. Also, 36(24%) subjects were recreationally active, while 114(76%) were recreationally inactive. The freely mobile subjects managed to finish the Five Times Sit to Stand Test in less time than the other groups (p<0.05). The recreationally active subjects took significantly less time to finish the Timed Up and Go test compared to the inactive. Besides, the males had longer Single-Leg Stance Test timing than females (p<0.05). CONCLUSIONS: The elderly belonging to different Timed Up and Go mobility categories demonstrated variable Five Times Sit to Stand abilities, with the recreational mobility status significantly affecting the category.

Trunk extensors endurance with arms parallel to the trunk is superior to other arms positions: Randomized controlled trial.

Objectives: To compare the effect of arms positions on the static endurance ability of trunk extensors, and to investigate the effect of home endurance training of trunk extensors on isokinetic outputs. METHODS: The prospective, randomised, assessor-blinded, controlled- intervention study was conducted from December 2017 to October 2019 at the College of Medical Rehabilitation Sciences, Taibah University, Madinah, Saudi Arabia, and comprised males aged 20-24 years who were randomly assigned to one of the four groups. Group A had their hands above the head, group B had their hands behind the head, group C had their hands parallel to their trunk, and group D had their hands on the chest. Data was collected at baseline, and after 6 and 8 weeks of static trunk extensors endurance training. Isokinetic outputs of peak torque and average power were also measured. Data was analysed using SPSS 23. RESULTS: Of the 60 participants, 15(25%) were in each of the four groups. The overall mean age was 22.02±1.2 years. At baseline, there was no significant difference among the groups (p>0.05). There was significant intra-group improvement for all outcome variables after 6 and 8 weeks of training (p<0.05). CONCLUSIONS: Static endurance of the trunk extensors with having arms parallel to the trunk was superior to other arm positions, especially after six and eight weeks of training but didn't affect the isokinetic outputs. Clinical Trial Number: NCT03107676.

Combined top-down approach with low-power thulium laser enucleation of prostate: evaluation of one-year functional outcomes.

OBJECTIVES: To evaluate the safety and efficacy of combined top and down low power thulium laser enucleation of the prostate (ThuLEP). PATIENTS AND METHODS: Between May 2017 and May 2019, after institutional board review approval, successfully consented patients underwent combined top and down low power ThuLEP. We used a 30 -W Thulium laser with a 550 µm laser fiber and a 26 Fr continuous flow resectoscope. We collected data related to prostate size, enucleation time, morcellation time, perioperative complications, and early outcomes. RESULTS: Sixty patients underwent combined Top and down low power ThuLEP with mean age 67 ± 8. Acute urine retention was the main indication for surgery in 22% of patients, while the remaining had mean IPPS score 26 ± 3. The mean prostate volume was 102 ± 25 ml and the mean Qmax was 6 ± 2 ml/sec. Mean operative time was 103 ± 25 min, while; mean enucleation time was 80 ± 12 min, and mean morcellation time was 17 ± 6 min. The mean enucleated prostate volume was 73 ± 16 g and the mean hemoglobin drop was 1 ± 0.2 mg/dl. There was no need for blood transfusion and the mean hospital stay was 18 ± 4 h and catheters were removed on discharge. The 1st visit was at one month, and we observed significant mean Qmax improvement18 ± 5 ml/s. Our results showed no significant change of IIEF-5 score at 12-month follow-up compared to baseline. CONCLUSION: Low-power Thulium enucleation with a combined top and down technique provided a safe and efficacious outcome, that may reduce strenuous wrist flexion and eliminate the need for high-power Thulium laser device.

Clinical features, biochemistry, and HLA-DRB1 status in youth-onset type 1 diabetes in Sudan.

OBJECTIVE: To further understand clinical and biochemical features, and HLA-DRB1 genotypes, in new cases of diabetes in Sudanese children and adolescents. RESEARCH DESIGN AND METHODS: Demographic characteristics, clinical information, and biochemical parameters (blood glucose, HbA1c, C-peptide, autoantibodies against glutamic acid decarboxylase 65 [GADA] and insulinoma-associated protein-2 [IA-2A], and HLA-DRB1) were assessed in 99 individuals <18 years, recently (<18 months) clinically diagnosed with T1D. HLA-DRB1 genotypes for 56 of these Arab individuals with T1D were compared to a mixed control group of 198 healthy Arab (75%) and African (25%) individuals without T1D. RESULTS: Mean ± SD age at diagnosis was 10.1 ± 4.3 years (range 0.7-17.6 years) with mode at 9-12 years. A female preponderance was observed. Fifty-two individuals (55.3%) presented in diabetic ketoacidosis (DKA). Mean ± SD serum fasting C-peptide values were 0.22 ± 0.25 nmol/L (0.66±0.74 ng/ml). 31.3% were autoantibody negative, 53.4% were GADA positive, 27.2% were IA-2A positive, with 12.1% positive for both autoantibodies. Association analysis compared to 198 controls of similar ethnic origin revealed strong locus association with HLA-DRB1 (p < 2.4 × 10-14 ). Five HLA-DRB1 alleles exhibited significant T1D association: three alleles (DRB1*03:01, DRB1*04:02, and DRB1*04:05) were positively associated, while three (DRB1*10:01, DRB1*15:02, and DRB1*15:03) were protective. DRB1*03:01 had the strongest association (odds ratio = 5.04, p = 1.7 × 10-10 ). CONCLUSIONS: Young Sudanese individuals with T1D generally have similar characteristics to reported European-origin T1D populations. However, they have higher rates of DKA and slightly lower autoantibody rates than reported European-origin populations, and a particularly strong association with HLA-DRB1*03:01.

Stem Cell Therapy in Single-Ventricle Physiology: Recent Progress and Future Directions.

Current surgical and medical treatment options for single ventricle physiology conditions remain palliative. On the long term, despite treatment, the systemic ventricle has a significant risk of developing failure. There are unmet needs to develop novel treatment modalities to help ameliorate the ventricular dysfunction. Advances in the field of stem cell therapy have been promising for the treatment of heart failure. Numerous stem cell populations have been identified. Preclinical studies in small and large animal models provide evidence for effectiveness of this treatment modality and reveal several mechanisms of action by which stem cells exert their effect. Many clinical trials have been designed to further investigate the therapeutic potential that stem cell therapy may hold for pediatric populations with single ventricle physiology. In this review, we discuss the stem cell types used in these populations, some preclinical studies, and the clinical trials of stem cell therapy in single ventricle patients.

Pharmacogenomics in diabetes: outcomes of thiamine therapy in TRMA syndrome.

AIMS/HYPOTHESIS: Diabetes is one of the cardinal features of thiamine-responsive megaloblastic anaemia (TRMA) syndrome. Current knowledge of this rare monogenic diabetes subtype is limited. We investigated the genotype, phenotype and response to thiamine (vitamin B1) in a cohort of individuals with TRMA-related diabetes. METHODS: We studied 32 individuals with biallelic SLC19A2 mutations identified by Sanger or next generation sequencing. Clinical details were collected through a follow-up questionnaire. RESULTS: We identified 24 different mutations, of which nine are novel. The onset of the first TRMA symptom ranged from birth to 4 years (median 6 months [interquartile range, IQR 3-24]) and median age at diabetes onset was 10 months (IQR 5-27). At presentation, three individuals had isolated diabetes and 12 had asymptomatic hyperglycaemia. Follow-up data was available for 15 individuals treated with thiamine for a median 4.7 years (IQR 3-10). Four patients were able to stop insulin and seven achieved better glycaemic control on lower insulin doses. These 11 patients were significantly younger at diabetes diagnosis (p = 0.042), at genetic testing (p = 0.01) and when starting thiamine (p = 0.007) compared with the rest of the cohort. All patients treated with thiamine became transfusion-independent and adolescents achieved normal puberty. There were no additional benefits of thiamine doses >150 mg/day and no reported side effects up to 300 mg/day. CONCLUSIONS/INTERPRETATION: In TRMA syndrome, diabetes can be asymptomatic and present before the appearance of other features. Prompt recognition is essential as early treatment with thiamine can result in improved glycaemic control, with some individuals becoming insulin-independent. DATA AVAILABILITY: SLC19A2 mutation details have been deposited in the Decipher database ( https://decipher.sanger.ac.uk/ ).

Acetylcholinesterase biosensor based on a gold nanoparticle-polypyrrole-reduced graphene oxide nanocomposite modified electrode for the amperometric detection of organophosphorus pesticides.

A nanohybrid of gold nanoparticles, polypyrrole, and reduced graphene oxide sheets (named as Au-PPy-rGO) was achieved by electrochemical deposition of reduced graphene oxide with pyrrole and the introduction of gold nanoparticles. Acetylcholinesterase (AChE) was further encapsulated in a silica matrix and immobilized on the Au-PPy-rGO nanocomposite by co-deposition with (NH4)2SiF6. The presence of PPy helped to avoid the aggregation of rGO caused by van der Waals interactions between individual sheets and significantly increased the surface area of the modified electrode. The obtained Au-PPy-rGO nanocomposite not only showed excellent conductivity but also exhibited a high electrocatalytic activity and specific affinity for thiocholine, the hydrolysis product of the enzyme, and thus an improved detection sensitivity. Since AChE molecules were protected by the circumambient silica matrix, which provided a biocompatible environment and facilitated mass transport, the fabricated AChE biosensor displayed high stability and excellent activity together with a fast response to organophosphorus pesticides. Under optimum conditions, the biosensor led to the rapid and sensitive detection of paraoxon-ethyl from 1.0 nM to 5 µM with a detection limit of 0.5 nM.

Synthesis of novel indenoquinoxaline derivatives as potent α-glucosidase inhibitors.

A series of new N-(11H-Indeno[1,2-b]quinoxalin-11-ylidene)benzohydrazide derivatives (3a-3p) were synthesized and evaluated for their α-glucosidase inhibitory activity. The synthesized compounds 3d, 3f, 3g, 3k, 3n, 3p and 4 showed significant α-glucosidase inhibitory activity as compared to acrabose, a standard drug used to treat type II diabetes. Structures of the synthesized compounds were determined by using FT-IR, (1)H NMR, (13)C NMR, mass spectrometry and elemental analysis techniques.

Mutations in SECISBP2 result in abnormal thyroid hormone metabolism.

Incorporation of selenocysteine (Sec), through recoding of the UGA stop codon, creates a unique class of proteins. Mice lacking tRNA(Sec) die in utero, but the in vivo role of other components involved in selenoprotein synthesis is unknown, and Sec incorporation defects have not been described in humans. Deiodinases (DIOs) are selenoproteins involved in thyroid hormone metabolism. We identified three of seven siblings with clinical evidence of abnormal thyroid hormone metabolism. Their fibroblasts showed decreased DIO2 enzymatic activity not linked to the DIO2 locus. Systematic linkage analysis of genes involved in DIO2 synthesis and degradation led to the identification of an inherited Sec incorporation defect, caused by a homozygous missense mutation in SECISBP2 (also called SBP2). An unrelated child with a similar phenotype was compound heterozygous with respect to mutations in SECISBP2. Because SBP2 is epistatic to selenoprotein synthesis, these defects had a generalized effect on selenoproteins. Incomplete loss of SBP2 function probably causes the mild phenotype.

Thirty versus 60-Watt thulium laser enucleation of prostate: Toward the development of low-power anatomical enucleation of the prostate.

Introduction: We aimed to study whether using 30 W versus 60 W thulium enucleation of the prostate (ThuLEP) would affect postoperative outcomes in patients with benign prostatic hyperplasia (BPH). Materials and Methods: We prospectively identified male patients with moderate or severe lower urinary tract symptoms due to BPH. We randomized patients into 30 W (Group 1) or 60 W (Group 2) thulium yag laser with a 550 µm laser fiber and a 26 Fr continuous flow resectoscope. We collected data related to prostate size, enucleation time, morcellation time, laser time, perioperative complications, and 1-year functional outcomes. Results: A total of 120 patients were included, with a mean age of 67 years and a mean prostate size of 105 g. The preoperative characteristics were similar across both groups. The mean operative time was shorter in the 60 W group, 74 ± 27 vs. 91 ± 33 min in the 30 W group (P = 0.001), and the mean laser time was 55 ± 20 in 60 W versus 71 ± 25 in 30 W (P = 0.0001). The mean hospital stay was 1 day in both groups and at 1-year follow-up; there was a similar improvement in mean Qmax and International Prostate Symptom Score symptom scores. Discussion/Conclusion: Both 30 and 60 W ThuLEP provided a safe and comparable outcome with a relatively shorter operative time for the 60 W groups. Perhaps using a 30-W setting would be beneficial in the early learning curve or cases with more bleeding capsular perforators; besides, the financial benefit of manufacturing low-cost low-power devices that may help in the widespread of AEEP.

Servo torque fault diagnosis implementation for heavy-legged robots using insufficient information.

The reliability of sensors and servos is paramount in diagnosing the Heavy-Legged Robot (HLR). Servo faults stemming from mechanical wear, environmental disturbances, or electrical issues pose significant challenges to traditional diagnostic methods, which rely heavily on delicate sensors. This study introduces a framework that solely relies on joint position and permanent magnet synchronous motor (PMSM) information to mitigate dependency on fragile sensors for servo-fault diagnosis. An essential contribution involves refining a model that directly connects PMSM currents to HLR motion. Moreover, to address scenarios where actual servo outputs and HLR cylinder velocities are unavailable, an improved sliding mode observer (ISMO) is proposed. Additionally, a Fourier expansion model characterizes the relationship between operation time and fault-free disturbance in the HLR. Subsequently, the dual-line particle filter (DPF) algorithm is employed to predict fault-free disturbance. The outputs of DPF serve as a feedforward to the ISMO, enabling the real-time servo torque fault diagnosis. The accuracy and validity of this technical framework are verified through various simulations in MATLAB/SIMSCAPE and real-world experiments.

Suspected colchicine-induced late myocardial rupture occurring after the late presentation of acute inferior ST-elevation myocardial infarction.

Colchicine is one of the established drugs of choice for post-myocardial infarction (MI) induced pericarditis, given its anti-inflammatory properties. Recently, colchicine received FDA approval for secondary prevention of atherosclerotic cardiovascular disease, which leads to concerns regarding its anti-healing effects on myocardial tissue post-infarction. We present a case of a suspected colchicine-induced myocardial rupture in an elderly male, who presented with a syncopal episode while on colchicine three weeks after the late presentation of infero-posterior ST-elevation myocardial infarction.

The occurrence of ST elevation myocardial infarction (STEMI) and non-STEMI in patients with post traumatic stress disorder (PTSD) using the large nationwide inpatient sample (NIS).

BACKGROUND: PTSD leads to increased levels of stress hormones and dysregulation of the autonomic nervous system which may trigger cardiac events. The goal of this study is to evaluate any association between PTSD and the occurrence of STEMI and NSTEMI using a large database. METHOD: Using the Nationwide Inpatient Sample (NIS) and ICD-9 codes from 2005 to 2014 (n=1,621,382), we performed a univariate chi-square analysis of in-hospital occurrence of STEMI and NSTEMI in patients greater than 40 years of age with and without PTSD. We also performed a multivariate analysis adjusting for baseline characteristics including age, gender, diabetes, race, hyperlipidemia, hypertension, and tobacco use. RESULTS: The 2005-2014 dataset contained 401,485 STEMI patients (745, or 0.19%, with PTSD) and 1,219,897 NSTEMI patients (2,441, or 0.15%, with PTSD). In the 2005 dataset, 0.5% of PTSD patients had STEMI compared to 1.0% of non-PTSD patients (OR=0.46, 95% C.I., 0.36-0.59). Similarly, 0.6% of patients with PTSD and 2.2% of patients without PTSD had NSTEMI (OR=0.28, 95% C.I., 0.23-0.35). In the 2014 dataset, 0.3% of PTSD patients had STEMI compared to 0.7% of non-PTSD patients (OR=0.43, 95% C.I., 0.35-0.51). Similarly, 1.4% of patients with PTSD versus 2.9% of patients without PTSD had NSTEMI (OR=0.48, 95% C.I., 0.44-0.52). Similar trends were seen throughout the ten-year period. After adjusting for age, gender, diabetes, race, hyperlipidemia, hypertension, and tobacco use, PTSD was associated with a lower occurrence of STEMI (2005: OR=0.50, 95% C.I., 0.37-0.66; 2014: OR=0.35, 95% C.I., 0.29-0.43) and NSTEMI (2005: OR=0.44, 95% C.I., 0.34-0.57; 2014: OR=0.63, 95% C.I., 0.58-0.69). CONCLUSION: Using a large inpatient database, we did not find an increased occurrence of STEMI or NSTEMI in patients diagnosed with PTSD, suggesting that PTSD is not an independent risk factor for myocardial infarction.

Fabrication and Investigation of Deformable Rubber-Carbon Nanotube-Glue Gel-Based Impedimetric and Capacitive Tactile Sensors for Pressure and Displacement Measurements.

Carbon nanotube-glue composite gel-based surface-type elastic sensors with a cylindrical shape deformable (flexible) metallic body were fabricated for tactile pressure and compressive displacement sensing. The fabrication of the sensors was performed using the rubbing-in technique. The effect of the pressure and the compressive displacement on the capacitance and the impedance of the sensors were investigated at various frequencies (in the range of 1 kHz to 200 kHz). It was found that under the effect of pressure from 0 to 9 g/cm2, the capacitance increased by 1.86 and 1.78 times, while the impedance decreased by 1.84 and 1.71 times at the frequencies of 1 kHz to 200 kHz, respectively. The effect of displacement on the impedance and the capacitance of the device was also investigated at various frequencies from 1 kHz to 200 kHz. The results showed that under the effect of compressive displacement up to 25 µm, the impedance of the sensors decreased on average by 1.19 times, while the capacitance increased by 1.09 times, accordingly. The frequency response of the displacement sensor showed that it matched with the low-pass filter. The obtained results are explained based on changes in the shape and geometrical parameters of the cylindrical-shaped conductive body. These results have also been explained on the basis of the distance between the conductive plates of the capacitive sensors during compression, which takes place under the effect of applied pressure or displacement. Moreover, the design of the sensors is simple and easy to fabricate, and their use is also earthy. The fabricated sensors have great potential for commercialization.

Hypercalcemia as a rare presentation of hyaline fibromatosis syndrome from different Sudanese families: two case reports.

BACKGROUND: Hyaline fibromatosis syndrome is a rare progressive autosomal recessive connective tissue disorder caused by a mutation in the ANTXR2/CMG2 gene. According to its severity, patients may present with skin nodules or visceral infiltration, which carries a poor prognosis. Hypercalcemia has not been reported as a presenting feature of this syndrome. Stimulation of osteoclasts by inflammatory factors and immobilization--induced hypercalcemia have played role in the pathophysiology. To our knowledge, this is the first report of hypercalcemia-associated hyaline fibromatosis syndrome. CASE PRESENTATION: Here, we describe cases of two Sudanese patients, a boy aged 9 months and a girl aged 3.5 years with hypercalcemia as an associated presenting feature of hyaline fibromatosis syndrome. Other features include gingival hypertrophy, painful joint swellings, and restriction of movement, which was misdiagnosed as juvenile rheumatoid arthritis. Workup showed normal phosphate, normal to mildly elevated parathyroid hormone, low vitamin D 25. Genetic testing confirmed the mutation of the ANTXR2/CMG2 gene. Both patients responded well to medical therapy for hypercalcemia, but one of them with the severe form of juvenile hyaline fibromatosis died due to sepsis, while the other one has maintained normocalcemic status. CONCLUSIONS: These cases highlight the rare presentation of this syndrome and reflect the importance of biopsy and genetic testing in reaching the diagnosis, especially when the clinical presentation can mimic other inflammatory bone disorders. Calcium levels should be checked in such cases.

Characterization of Hashimoto´s thyroiditis in Sudanese children: a cross-sectional study at Gaafar Ibnauf Hospital, Khartoum.

Introduction: literature on Hashimoto´s thyroiditis, the common thyroid illness in the young populations, in Sudan and Africa is scarce. We aimed to study its clinical profile and outcome among Sudanese children and adolescents. Methods: records of 73 patients were reviewed. Data related to demographics, presenting features, family history and coexistence of autoimmune diseases, physical examination findings, and biochemical progression over time were obtained. Results: patients´ mean age at the diagnosis was 10.6 ± 2.9 years, 80.8% (n = 59) of them were female and 83.6% (n = 61) were residing in iodine-sufficient areas. The commonest presenting features were thyromegaly and fatigability (79.5%, n = 58 and 43.8%, n = 32, respectively) after an illness duration of 0.5-48 months. Autoimmune comorbidities were documented in 8.2% (n = 6) of our series and more than half (53.4%, n = 39) of them were pre-pubertal at the diagnosis. Sixty point three percent (60.3%) (n = 44), 20.5% (n = 15), 13.7% (n = 10) and 5.5% (n = 4) of patients presented with overt hypothyroidism, sub-clinical hypothyroidism, euthyroidism and hyperthyroidism respectively, and there were no significant differences in the clinical profile between them. In patients' continued follow-up, 94.1% (n = 32/34) of those presented with overt hypothyroidism required levothyroxine therapy to maintain euthyroidism for 0.5-13 years, while 85.7% (n = 6/7) of those with euthyroidism remained so for 0.5-6 years. Remission was reported in all hyperthyroid patients and in only 5.9% (n = 2/34) of those with overt hypothyroidism at diagnosis. The majority of our patients with subclinical hypothyroidism were treated with levothyroxine and continued to be euthyroid for 10 months to 13 years. Conclusion: goiter was the commonest presenting feature of Hashimoto´s thyroiditis. The majority of patients had overt or subclinical hypothyroidism and almost all of them required long-term levothyroxine therapy.

Central precocious puberty in Sudan: 10 years' experience of paediatric endocrinology centres.

Central precocious puberty (CPP) is frequently seen among cases presenting to our endocrine clinics. The purpose of this study was to have base line data on this condition with an attempt to point out any possible unique features of Sudan and to explore challenges faced in management and how that cultural and traditional practices may hamper care. Here, we are reporting the first data on this aspect from Sudanese subjects. Patients labelled as having CPP in Gafaar Ibnauf Children's Hospital and Soba University Hospital Endocrinology Clinics from January 2006 to 2016 are included in a descriptive hospital-based study which was conducted over 10 years in these two main paediatric endocrinology centres. Records of all patients with CPP were reviewed and challenges in diagnosis and management were identified. Most of the children with CPP presented late. Organic causes were more frequent among girls than what has been reported in the literature; in most boys, it was idiopathic. Almost half of the patients with underlying pathology were older than 6 years of age. Most cases including girls have an organic cause, thus magnetic resonance image should be done in all patients. Management of precocious puberty in a resource-limited country is faced with various challenges (e.g., expensive investigations and medications). We suggest establishing a unified protocol for managing these cases and creating collaboration between governmental, nongovernmental organisations and health services.
