Clinical, biochemical, and molecular insights into Cerebrotendinous Xanthomatosis: A nationwide study of 100 Turkish individuals.

OBJECTIVE: Cerebrotendinous xanthomatosis (CTX) is an inherited metabolic disorder characterized by progressive neurologic and extraneurologic findings. The aim of this retrospective, descriptive study was to explore the time of presentation and diagnosis, and to expand the phenotype and genotype of CTX, based on a nationwide and comprehensive series of patients in Turkey. METHODS: The demographic, clinical, biochemical and genotypic characteristics of the CTX patients were reviewed. Data on molecular analysis, age of onset and diagnosis, diagnostic delay, neurologic and extraneurologic symptomatology, results of plasma cholestanol levels, brain magnetic resonance imaging and electromyography at the time of diagnosis were reviewed. RESULTS: 100 confirmed CTX patients from 72 families were included. The mean age at diagnosis was 28.16 ± 14.28 years, and diagnostic delay was 18.39 ± 13.71 years. 36 patients were diagnosed in childhood. Frequency of intention tremor (p = 0.069), peripheral neuropathy (p = 0.234) and psychiatric manifestations (p = 0.396) did not differ between two groups, demonstrating the high rate in pediatric patients. Three adult patients showed a milder phenotype without neurologic involvement. Seven patients had normal plasma cholestanol levels despite neurological impairment. Sequencing of the CYP27A1 gene revealed 25 different variants, with a novel c.671_672del variant not previously described in literature. CONCLUSION: Based on the observations of this Turkish CTX cohort, it is emphasized that the true prevalence of CTX is probably underestimated and that it has a wide spectrum of clinical phenotypes even without neurological impairment. In children, abnormal cerebellar findings, peripheral neuropathy and psychiatric findings associated with intellectual disability have been suggested as warning signs to avoid diagnostic delay. In cases of clinical suspicion, molecular analysis is recommended despite normal plasma cholestanol levels, as severe neurologic involvement may occur in CTX patients without elevated cholestanol levels.

Long-term personalized high-protein, high-fat diet in pediatric patients with glycogen storage disease type IIIa: Evaluation of myopathy, metabolic control, physical activity, growth, and dietary compliance.

Dietary lipid manipulation has recently been proposed for managing glycogen storage disease (GSD) type IIIa. This study aimed to evaluate the myopathic, cardiac, and metabolic status, physical activity, growth, and dietary compliance of a personalized diet high in protein and fat for 24 months. Of 31 patients with type IIIa GSD, 12 met the inclusion criteria. Of these, 10 patients (mean age 11.2 ± 7.4 years) completed the study. Patients were prescribed a personalized high-protein, high-fat diet, comprising 3.0-3.5 g/kg/day of protein and 3.0-4.5 g/kg/day of fat, constituting 18.5%-28% and 70.5%-75.7% of daily energy, respectively. Dietary compliance was ensured and assessed via the regular administration of questionnaires. Our results revealed consistent and significant decreases of 22%, 54%, and 30% in the creatinine kinase, creatine kinase-myocardial band, and lactate dehydrogenase levels, respectively. Echocardiography revealed improvements in the Z-scores of the left ventricular mass and interventricular septum thickness. A significant increase in body muscle mass was observed, and a higher score was achieved using the Daily Activity Questionnaire. Growth monitoring revealed an arrest in the height-SDS at the 6th and 12th months, followed by subsequent improvement at the end of the second year. A gradual and persistent decline in the periods of hypo- and hyperglycemia has been reported. Biotinidase activity decreased, whereas hepatosteatosis increased and then decreased by the end of the study. Implementing a high-protein, high-fat diet and monitoring key parameters in patients with type IIIa GSD can lead to myopathic and cardiac improvements and increased physical activity.

The effect of clay therapy on hopelessness and depression levels in chronic stroke patients in addition to physical therapy.

BACKGROUND: Clay art therapy can be used as part of rehabilitation for chronic stroke patients. OBJECTIVE: The objective of this study is to examine the effect of clay therapy on hopelessness and depression levels in chronic stroke patients who receive physical therapy and compare them to patients who only receive physical therapy. METHODS: This randomized controlled study was conducted between August 1st - September 28th, 2022 in Turkiye, with 60 patients who agreed to participate in the study and met the inclusion criteria, which were chronic stroke patients who received physical therapy. The patients were divided into two groups (30 in the experimental group, 30 in the control group) with the control group receiving only their routine physical therapy and rehabilitation (5 days a week, 40 sessions in total), while the experimental group received their routine physical therapy and rehabilitation program as well as clay therapy twice a week, 60 min per session, for 8 weeks. Demographic information of all the participants was recorded, and the Beck Depression Inventory and Beck Hopelessness Scale were administered before and after treatment. RESULTS: The patients' depression posttest scores (t(58) = -11.386; p = 0.000 < 0,05), and hopelessness posttest scores (t(58) = -10.247; p = 0.000 < 0,05) differed significantly based on their groups. The control group's depression posttest scores (x¯ =25,033) and hopelessness posttest scores (x¯ =15,000) were higher than the experimental group's depression posttest scores (x¯ =9,067) and hopelessness posttest scores (x¯ =8,000). The control group's feeling about the future posttest scores (x¯ =2,967) were higher than the experimental group's posttest scores (x¯ =0,967). The control group's loss of motivation posttest scores (x¯ =6,400) were higher than the experimental group's posttest scores (x¯ =2,667). CONCLUSION: It was seen that clay therapy, in addition to physical therapy, was effective in reducing depression and hopelessness in chronic stroke patients.

Long-term clinical outcomes and management of hypertriglyceridemia in children with Apo-CII deficiency.

BACKGROUND AND AIM: APO CII, one of several cofactors which regulate lipoprotein lipase enzyme activity, plays an essential role in lipid metabolism. Deficiency of APO CII is an ultra-rare autosomal recessive cause of familial chylomicronemia syndrome. We present the long-term clinical outcomes of 12 children with APO CII deficiency. METHODS AND RESULTS: The data of children with genetically confirmed APO CII deficiency were evaluated retrospectively. Twelve children (8 females) with a mean follow-up of 10.1 years (±3.9) were included. At diagnosis, the median age was 60 days (13 days-10 years). Initial clinical findings included lipemic serum (41.6%), abdominal pain (41.6%), and vomiting (16.6%). At presentation, the median triglyceride (TG) value was 4341 mg/dL (range 1277-14,110). All patients were treated with a restricted fat diet, medium-chain triglyceride (MCT), and omega-3-fatty acids. In addition, seven patients (58.3%) received fibrate. Fibrate was discontinued in two patients due to rhabdomyolysis and in one patient because of cholelithiasis. Seven (58.3%) patients experienced pancreatitis during the follow-up period. One female experienced recurrent pancreatitis and was treated with fresh frozen plasma (FFP). CONCLUSIONS: Apo CII deficiency is an ultra-rare autosomal recessive condition of hypertriglyceridemia associated with significant morbidity and mortality. Low-fat diet and MCT supplementation are the mainstays of therapy, while the benefit of TG-lowering agents are less well-defined.

Development of a New Amperometric Biosensor for Measurement of Plasma Galactose Levels.

Galactosemia is an inherited disease that occurs as a result of insufficient or no synthesis of some enzymes (GALT, GALK, and GALE) in galactose metabolism. Failure to make an early diagnosis, especially in newborns, can lead to severe clinical and even fatal consequences. The aim of this study is to develop a biosensor for measuring free galactose in plasma. The immobilization components of the developed free galactose biosensor are screen printed carbon electrode (SCPE), Prussian blue (PB), chitosan (CHIT), Nafion (NAF), gold nanoparticle (GNP), and galactose oxidase (GaOX). The CHIT/GaOX/NAF-GNP/GaOX/CHIT-GNP/SCPE-PB electrode showed a sensitive amperometric response to detect galactose. While the surface characterization of the biosensor was performed with cyclic voltammetry and scanning electron microscopy, the optimization and performance characterizations were made by applying an amperometry technique. The amperometric operating potential for the free galactose biosensor was determined as -0.05 V. The linear detection range for the free galactose biosensor is between 0.025 and 10 mM. This range includes galactose levels in plasma of both healthy and patients. The percent coefficient of variation values calculated for intraday and interday repeatability of the developed biosensor are below 10%. The practical use of the biosensor, for which optimization and characterization studies were carried out, was tested in 10 healthy 11 patients with galactosemia, and the results were compared with the colorimetric method. In conclusion, the unique analytical properties and effortless preparation of the new galactose biosensor developed in this study make them serious candidates for point-of-care diagnostic testing.

Experience with carnitine palmitoyltransferase II deficiency: diagnostic challenges in the myopathic form.

OBJECTIVES: Carnitine palmitoyltransferase II (CPT II) deficiency is an autosomal recessive disorder of long-chain fatty acid oxidation. Three clinical phenotypes, lethal neonatal form, severe infantile hepatocardiomuscular form, and myopathic form, have been described in CPT II deficiency. The myopathic form is usually mild and can manifest from infancy to adulthood, characterised by recurrent rhabdomyolysis episodes. The study aimed to investigate the clinical features, biochemical, histopathological, and genetic findings of 13 patients diagnosed with the myopathic form of CPT II deficiency at Ege University Hospital. METHODS: A retrospective study was conducted with 13 patients with the myopathic form of CPT II deficiency. Our study considered demographic data, triggers of recurrent rhabdomyolysis attacks, biochemical metabolic screening, and molecular analysis. RESULTS: Ten patients were examined for rhabdomyolysis of unknown causes. Two patients were diagnosed during family screening, and one was diagnosed during investigations due to increased liver function tests. Acylcarnitine profiles were normal in five patients during rhabdomyolysis. Genetic studies have identified a c.338C>T (p.Ser113Leu) variant homozygous in 10 patients. One patient showed a novel frameshift variant compound heterozygous with c.338C>T (p.Ser113Leu). CONCLUSIONS: Plasma acylcarnitine analysis should be preferred as it is superior to DBS acylcarnitine analysis in diagnosing CPT II deficiency. Even if plasma acylcarnitine analysis is impossible, CPT2 gene analysis should be performed. Our study emphasizes that CPT II deficiency should be considered in the differential diagnosis of recurrent rhabdomyolysis, even if typical acylcarnitine elevation does not accompany it.

Glycosaminoglycan-induced proinflammatory cytokine levels as disease marker in mucopolysaccharidosis.

Recently, it has been shown disturbances in oxidant/antioxidant system and increases in some inflammatory markers in animal studies and in some Mucopolysaccharidoses (MPSs) patients. In this study, we aimed to determine the oxidative stress/antioxidant parameters and pro-inflammatory cytokine levels in the serum of MPS patients, in order to evaluate the possible role of inflammation in these patient groups regarding to accumulated metabolites. MPS I (n = 3), MPS II (n = 8), MPS III (n = 4), MPS IVA (n = 3), MPS VI (n = 3), and VII (n = 1) patients and 20 age-matched healthy subjects were included into the study. There was no statistically significant change in activities of SOD, Catalase, GSH-Px and lipid peroxidation levels in erythrocytes between the MPS patients and healthy controls. While IL-1alpha (p = 0.054), IL-6 (p = 0.008) levels, and chitotriosidase activity (p = 0.003) elevated in MPS3 patients, IL1α (p = 0.006), IL-1ß (p = 0.006), IL-6 (p = 0.006), IFNγ (p = 0.006), and NFκB (p = 0.006) levels increased in MPS-6 patients. Elevated levels of IL-6, IL1α and chitotriosidase activity demonstrated macrophage activation in MPSIII untreated with enzyme replacement. Our study showed for the first time that high levels of IL1α, IL-6, IL1ß and NFκB were present in MPSVI patients, demonstrating the induction of inflammation by dermatan sulphate. The low level of paraoxonase in MPSVI patients may be a good marker for cardiac involvement. Overall, this study provides important insights into the relationship between lysosomal storage of glycosaminoglycan and inflammation in MPS patients. It highlights possible pathways for the increased release of inflammatory molecules and suggests new targets for the development of treatments.

COVID-19 and Vaccination Status in Lysosomal Storage Diseases: A Single-Center Experience.

OBJECTIVE: Coronavirus disease 2019 (COVID-19) causes significant morbidity and mortality in individuals with chronic disease. There is not enough information about the course of coronavirus disease in lysosomal storage diseases. This study aimed to evaluate coronavirus disease vaccination status and the impact of coronavirus disease on lysosomal storage disease. MATERIALS AND METHODS: The study included 87 lysosomal storage disease patients. The patients' diagnoses were Gaucher, mucopolysaccharidosis I, II, IVA, VI, VII, Fabry, and Pompe. A questionnaire assessing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) exposure, coronavirus disease symptoms, and vaccine status was administered in person or by phone calls. RESULTS: The number of coronavirus disease positive patients was 8 (9.1%). Only 2 patients were treated in the intensive care unit. Other coronavirus disease patients had mild symptoms and stayed in-home quarantine. Patients over 12 years of age could receive a COVID-19 vaccine. 63.5% of those aged ≥12 years were vaccinated. CONCLUSION: Lysosomal storage disease patients did not have an increased risk of COVID-19 compared to the healthy population, despite the chronic inflammatory disease. Vaccination of lysosomal storage disease patients will be protective against severe coronavirus disease.

Trait anger - Anger expression style and coping with stress in alcohol and substance use disorders: A randomized and controlled study.

PURPOSE: The objective of this randomized controlled study is to analyze the effect of nine-session psychoeducation on anger and stress coping abilities of individuals who are individuals with alcohol and substance use disorders. DESIGN AND METHODS: The single-blind research method was used in the experimental study in the pretest - posttest order. The study was conducted in the Alcohol and Drug Addiction Research, Treatment and Education Center (AMATEM) of a Training and Research Hospital, between July 1st and October 30th of 2021, with 61 patients (30 in experimental group, 31 in control group). The data was collected with Sociodemographic Information Form, Ways of Coping with Stress Scale (WCSI), and Trait Anger - Anger Expression Style Scale (STAI). The data was analyzed using mean, percentage distribution, standard deviation, Mann-Whitney U test, Wilcoxon test, Fisher-Exact test or "Pearson-χ2" and "Spearman" correlation coefficient. RESULTS: The age average of the experimental group is 33.48±9.28 and control group is 34.03±8.49.A statistically significant difference was detected in the experimental group in terms of pretest and posttest scores of WCSI and STAI subscales (p < 0.05). CONCLUSION: Psychoeducation program is observed to be effective in coping with stress and providing anger control in in-patients with the objective of this randomized controlled study is to analyze the effect of nine-session psychoeducation on anger and stress coping abilities of individuals who are individuals with alcohol and substance use disorders. PRACTICE IMPLICATIONS: The psychiatric nurse should ensure the continuation of the psychoeducation program for the objective of this randomized controlled study is to analyze the effect of nine-session psychoeducation on anger and stress coping abilities of individuals who are individuals with alcohol and substance use disorders.

Hematopoietic stem cell transplantation with reduced toxicity conditioning regimen in mitochondrial neurogastrointestinal encephalopathy syndrome.

BACKGROUND: Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is a rare autosomal recessive disorder due to mutations in the TYMP gene. Clinical findings are characterized by neurologic manifestations and severe gastrointestinal dysfunction. The syndrome is usually fatal, the most effective treatment appears to be hematopoietic stem cell transplantation (HSCT). PROCEDURE: In this retrospective study, we evaluated HSCT that was performed using a reduced toxicity myeloablative conditioning regimen in patients with MNGIE at our center. RESULTS: A total of six allogeneic transplant procedures were performed in four patients. Three patients had fully matched donors, and one patient had a haploidentical donor. Treosulfan-based myeloablative conditioning regimen was applied in five of six transplants. Bone marrow was used as a stem cell source. One patient is being followed up in the 4th year of posttransplant with full chimeric and without graft versus host disease (GVHD). One patient died of acute stage IV gastrointestinal system GVHD. Two patients underwent second transplantation due to engraftment failure, one of which was the patient who had a haploidentical transplant. CONCLUSIONS: Treosulfan-based regimen is well tolerated, although engraftment failure with this conditioning regimen can be a significant problem. We share our haploidentical transplant experience, which will be the first reported case in the literature.

Unique clinical presentations and follow-up outcomes from experience with congenital disorders of glycosylation: PMM2-PGM1-DPAGT1-MPI-POMT2-B3GALNT2-DPM1-SRD5A3-CDG.

OBJECTIVES: Congenital Glycosylation Disorders (CDG) are a large group of inherited metabolic diseases with multi-organ involvement. Herein, we aimed to expand the clinical characteristics of patients with CDG based on our experience with diagnoses and follow-up of CDG patients from different subtypes. METHODS: The clinical and laboratory findings from the last 15 years were reviewed retrospectively in Ege University Child Metabolism and Nutrition Department. RESULTS: There were 8 (57.2 %) females and 6 (42.8 %) males. Diagnoses of the patients were PMM2-CDG (n=4), PGM1-CDG (n=2), DPAGT1-CDG (n=2), SRD5A3-CDG (n=2), MPI-CDG (n=1), POMT2-CDG (n=1), B3GALNT2-CDG (n=1), DPM1-CDG (n=1). The clinical findings of the patients were dysmorphia (85.7 %), developmental delay (85.7 %), intellectual disability (85.7 %), ocular abnormalities (64.2 %), skeletal malformations (64.2 %), failure to thrive (57.1 %), microcephaly (57.1 %), hepatomegaly (35.7 %), hearing loss (35.7 %), seizures (28.5 %), gastrointestinal symptoms (21.4 %), endocrine abnormalities (21.4 %), and cardiac abnormalities (7.1 %). Laboratory findings were abnormal TIEF (92.8 %), abnormal liver enzymes (64.2 %), decreased protein C (64.2 %), decreased antithrombin III (64.2 %), decreased protein S (42.8 %), hypogammaglobulinemia (35.7 %), cerebellar hypoplasia (28.5 %), CK elevation (7.1 %), and hypoglycemia (7.1 %). CONCLUSIONS: This study contributes to the literature by sharing our ultra-rare DPM1-CDG case with less than 20 cases in the literature and expanding the clinical and molecular characteristics of other CDG patients. Hyperinsulinemic hypoglycemia, short stature, hypothyroidism, growth hormone deficiency, hypogammaglobulinemia, pericardial effusion, elevated CK, congenital myasthenia, and anorectal malformation were unique findings that were observed. Cerebello-ocular findings accompanying multi-organ involvement were an essential clue for a possible CDG.

Mild Aromatic L-Amino Acid Decarboxylase Deficiency: As A Reason For Hypoketotic Hypoglycemia In A 4-Year-Old Girl.

Aromatic L-amino acid decarboxylase (AADC) deficiency is a disease in which neurological findings are dominant due to deficiencies in neurotransmitter synthesis; hypoglycemia caused by autonomic dysfunction is one of the symptoms that may be encountered. Here we report a mild AADC deficiency presenting with hypoglycemia without a neurological sign. A 4-year-old girl presented with recurrent hypoglycemia. Her growth and development were normal. Plasma insulin and cortisol values were normal in the sample at the time of hypoglycemia. The C8:1-Carnitine elevation was detected in the acylcarnitine profile. The clinic exome panel was performed with the suggestion of a fatty acid oxidation defect. However, a homozygous variant in the DDC gene was detected. On top of that, CSF neurotransmitter analysis revealed low 5-hydroxy indol acetic ( 5 HIAA ) and homovanillic acid ( HVA ) and high 3-O-methyl-dopa and methyltetrahydrofolate ( 5 MTHF ) consistent with AADC deficiency. Plasma AADC enzyme activity was low. The episodes of hypoglycemia were treated with uncooked cornstarch. Our case emphasizes that AADC deficiency should be considered in patients with hypoglycemia.

Maximizing Pharmacological Treatment Adherence of Children and Adolescents: A Randomized Controlled Study.

The aim of the current randomized controlled study was to evaluate treatment adherence of children and adolescents who visited an outpatient psychiatry clinic and started medication for the first time, with telehealth application. This study was performed with parents of patients who visited the clinic from October 1, 2020, to March 31, 2021. Data were collected using a personal information form, Medication Control Form, and Morisky Medication Adherence Scale via telephone after verbal and written consent were obtained. It was found that 96.7% of participants in the experimental group had high medication adherence, whereas 93.3% of participants in the control group had low medication adherence. Results show that telehealth application is effective in maximizing adherence to treatment among children and adolescents.

Persistent moderate methylmalonic aciduria in a patient with methylmalonyl CoA epimerase deficiency.

BACKGROUND: Methylmalonyl CoA epimerase (MCE) deficiency was first reported in 2006 and only a few cases have been reported so far. The clinical spectrum of MCE deficiency ranges from asymptomatic to lifethreatening metabolic decompensation attacks. CASE: Herein we report a patient diagnosed with MCE deficiency with recurrent acute metabolic ketoacidosis attacks and moderate MMA-uria that persisted in periods without decompensation. At presentation, organic acid profiles were dominated by increased 3 hydroxybutyrate. CONCLUSIONS: 3-Oxothiolase deficiency as a main ketolysis defects disorder was initially suspected. However, the subsequently repeated organic acid analyses demonstrated mild and persistent elevation of methylmalonic acid. This report provides a new phenotype of the clinical and biochemical characterization of MCE deficiency.

Clinical spectrum of early onset "Mediterranean" (homozygous p.P131L mutation) mitochondrial neurogastrointestinal encephalomyopathy.

Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is an autosomal recessive mitochondrial disorder characterized by cumulative and progressive gastrointestinal and neurological findings. This retrospective observational study, aimed to explore the time of presentation, diagnosis and clinical follow-up of 13 patients with a confirmed MNGIE disease of Mediterranean origin. The mean age of symptom onset was 7 years (6 months-21 years) and the average diagnosis age was 15.4 years ±8.4. Four of 13 patients (30%) died before 30 years at the mean age of 19.7 years ±6.8. Cachexia and gastrointestinal symptoms were observed in all patients (100%). The mean body mass index standard deviation score at diagnosis was 4.8 ± 2.8. At least three subocclusive episodes were presented in patients who died in last year of their life. The main neurological symptom found in most patients was peripheral neuropathy (92%). Ten patients (77%) had leukoencephalopathy and the remaining three patients without were under 10 years of age. The new homozygous "Mediterranean" TYMP mutation, p.P131L (c.392 C > T) was associated with an early presentation and poor prognosis in nine patients (69%) from five separates families. Based on the observations from this Mediterranean MNGIE cohort, we propose that the unexplained abdominal pain combined with cachexia is an indicator of MNGIE. High-platelet counts and nerve conduction studies may be supportive laboratory findings and the frequent subocclusive episodes could be a negative prognostic factor for mortality. Finally, the homozygous p.P131L (c.392 C > T) mutation could be associated with rapid progressive disease with poor prognosis.

Nursing students' professional image in the Covid-19 pandemic in Turkey: A cross-sectional study.

BACKGROUND: Nursing students' professional perceptions are affected by the environment they live in. Nursing students think that the nursing profession is important during the pandemic. PURPOSE: This descriptive, cross-sectional study was conducted to determine the nursing students' professional image perceptions and the affecting factors during the Covid-19 pandemic in Turkey. METHODS: The research population consisted of all nursing students (N = 750) of two universities in Turkey. The research data were collected using a personal information form and the Scale for the Image of Nursing Profession (SINP). RESULTS: Of the students, 76.4% were not infected with Covid-19, 30.8% had an individual in their family infected with Covid-19; 34% had an immediate family member who died of Covid-19; 99.4% thought that the nursing profession is important during the Covid-19 pandemic. A statistically significant difference was found between the place where the students live and the SINP (p < .05). CONCLUSION: The students' image perceptions toward the nursing profession were found to be at a good level. This indicates that image perception toward nursing profession has increased during the pandemic. It can be said that the place where the students are in the pandemic process and their thoughts about the nursing profession affect their professional image perceptions.

Long-term follow-up of alkaptonuria patients: single center experience.

OBJECTIVES: Alkaptonuria is a rare autosomal recessive genetic disorder resulting from the deficiency of homogentisate 1,2 dioxygenase (HGD), the third enzyme in the tyrosine degradation pathway. Homogentisic acid produced in excess oxidizes into ochronotic pigment polymer. Accumulation of this pigment in various tissues leads to systemic disease. METHODS: Clinical, laboratory, molecular findings and treatment characteristics of 35 patients followed up in Ege University Pediatric Nutrition, and Metabolism Department with the diagnosis of alkaptonuria were evaluated retrospectively. RESULTS: Twenty-four males (68.57%) and 11 females (31.42%) with a confirmed diagnosis of alkaptonuria from 32 different families were included in the study. We identified 11 different genetic variants; six of these were novel. c.1033C>T, c.676G>A, c.664G>A, c.731_734del, c.1009G>T, c.859_862delins ATAC were not previously reported in the literature. 24 (68.57%) patients only adhered to a low-protein diet in our study group. Seven (20%) patients initiated a low protein diet and NTBC therapy. Mean urinary HGA decreased by 88.7% with nitisinone. No statistical changes were detected in urinary HGA excretion with the low protein diet group. CONCLUSIONS: In our study, alkaptonuria patients were diagnosed at different ages, from infancy to adulthood, and progressed with other systemic involvement in the follow-up. Since the initial period is asymptomatic, giving potentially effective treatment from an early age is under discussion. Raising disease awareness is very important in reducing disease mortality and morbidity rates.

The Insomnia and Loneliness of Elderly Individuals and Affecting Factors During the COVID-19 Pandemic in Turkey.

This study aims to examine the loneliness and sleep problems of older people and the variables during the COVID-19 in Turkey pandemic and the variables that affect them. Snowball sampling was used in this descriptive and cross-sectional study. Google forms, personal information form, the UCLA Loneliness Scale III and the Insomnia Severity Index were used to collect data in December 2020. The questionnaire link was disseminated by e-mail and social media. By clicking the link, the participants were automatically directed to information about the study and received informed consent forms. The participants were urged to send the questionnaire to as many individuals as they could. This research was conducted with 412 participants. Education level and perceived health status affected their loneliness. The older people had loneliness and sleep problems during the COVID-19 pandemic, and these problems were affected by sociodemographic variables. Loneliness and insomnia are positively correlated, and loneliness affects the severity of insomnia.

Older individuals who have low education levels, who describe themselves as introverted and as having poor health status, and who meet individuals diagnosed with COVID-19 are at more risk of loneliness and insomnia.Geriatric nursing practices should be planned to increase the consciousness of controlled social life in order for older people to be included in social life.Loneliness can cause sleep problems, and older people who feel lonely experience more insomnia.Determining which of the psychological and social needs of older individuals have not been met during the pandemic and detecting problems early are important to protecting public health.Global measures should be taken. It is important to develop social solutions and policies for the older people population's pandemic-related problems such as loneliness and insomnia.

Un caso de hipofosfatasia perinatal grave con una mutación novedosa / Severe perinatal hypophosphatasia case with a novel mutation

La hipofosfatasia es un trastorno hereditario raro causado por mutaciones en el gen ALPL. Causa defectos en la mineralización ósea y dental, función respiratoria anormal, convulsiones, hipotonía, dolor óseo y nefrocalcinosis. Las formas clínicas se reconocen según la edad al diagnóstico y la gravedad. Presentamos el caso de una lactante con fontanela anterior agrandada, bóveda craneal blanda, fracturas, dificultad respiratoria y convulsiones. El análisis bioquímico mostró hipercalcemia, fosfato sérico normal y fosfatasa alcalina sérica baja. La radiografía mostró hipomineralización, fracturas y callos. La concentración plasmática de piridoxal-5'-fosfato era de 762 mg/l (intervalo normal: 5-50) y la concentración de fosfoetanolamina en orina era de 1015 mmol/l (intervalo normal: 15-341). El análisis del gen ALPL mostró dos mutaciones heterocigotas compuestas, una de las cuales es novedosa. El diagnóstico y tratamiento tempranos de la hipofosfatasia perinatal podría mejorar los resultados y tener un impacto positivo en la sobrevida.

Hypophosphatasia (HPP) is a rare inherited disorder caused by mutations in the ALPL gene. Mineralization defect in bones and teeth, abnormal respiratory function, seizures, hypotonia, bone pain, and nephrocalcinosis can be observed. Clinical forms are usually recognized based on age at diagnosis and severity of features. We present an infant with an enlarged anterior fontanelle, soft calvarium, fractures, respiratory distress, and seizures. Biochemical analysis showed hypercalcemia, normal serum phosphate, and low serum alkaline phosphatase (ALP) levels. X-ray showed hypomineralization, fractures, and callus formations. Plasma pyridoxal 5'-phosphate (PLP) was 762 mg/L (NV : 5-50) and urine phosphoethanolamine (PEA) was 1015 mmol/L (NV : 15-341) and ALPL gene analysis showed two compound heterozygous mutations, one of which is a novel one. Early diagnosis and treatment of perinatal HPP may improve outcomes and might have a positive impact on survival.

Coexistencia infrecuente de la enfermedad de Tay-Sachs, coartación aórtica y reflujo vesicoureteral de grado V / Rare coexistence of Tay-Sachs disease, coarctation of the aorta and grade V vesicoureteral reflux

La enfermedad de Tay-Sachs es una enfermedad metabólica hereditaria neurodegenerativa. Existen cuatro tipos según el inicio de los síntomas clínicos: infantil, infantil de inicio tardío, juvenil y adulto. El tipo infantil tiene el peor pronóstico. Recientemente, se describieron diferentes anomalías que acompañan a los trastornos metabólicos e influyen en el pronóstico. Presentamos el caso de un lactante con enfermedad de Tay-Sachs junto con coartación aórtica y reflujo vesicoureteral bilateral (RVU) de grado V. Se realizó el seguimiento del paciente en el consultorio externo de Cardiología Pediátrica. En la ecografía abdominal, se observó ectasia pielocalicial, y se detectó reflujo vesicoureteral bilateral de grado V en la cistouretrografía miccional. No se ha informado previamente la coexistencia de estas anomalías. Este caso pone de manifiesto que no se deben subestimar las anomalías del examen neurológico en los pacientes con una cirugía cardíaca reciente, porque podría perderse la oportunidad de diagnosticar enzimopatías congénitas.

Tay-Sachs disease is a neurodegenerative inherited metabolic disease. There are four forms classified by the time of first clinical symptoms: infantile, late infantile, juvenile and adult. Infantile form has the poorest prognosis. Lately, different abnormalities which accompany metabolic disorders and affect the prognosis have been described. We present an infant with Tay-Sachs disease accompanied by coarctation of the aorta and bilateral grade V vesicoureteral reflux (VUR). The patient was followed up in the outpatient clinic of Pediatric Cardiology. The abdominal ultrasonography showed pelvicalyceal ectasia; bilateral grade V VUR in voiding cystourethrography was found. This coexistence has not been previously reported. This case emphasizes that abnormalities in the neurological examination of cardiac postsurgical patients should not be underestimated because the opportunity to diagnose inborn errors of metabolism could be missed.
