We described the case of a 2-month-old child was presented to the emergency department with a generalized seizure, which started 40 days after birth. The laboratory examination revealed hypocalcemia (3.4 mg/dL), normal albumin serum, elevated PTH level of 235.9 pg/mL, decreased vitamin D of 13.8 ng/dL, and normal renal function. The mother had not consumed vitamin D supplement during pregnancy and lactation. The patient had also been consuming phenobarbital since the age of 1 month due to a previous history of seizures. The disease was managed with oral administration of 10% calcium gluconate along with 5000 IU of vitamin D3 daily to manage calcium homeostasis. The treatment stabilized the patient's condition and there was rapid improvement in laboratory findings. After 6 months, the seizure disappeared and the level of vitamin D (25-hydroxy vitamin D) was normal, namely 80 ng/dL.

Introduction: In the COVID-19 pandemic, social restriction and lock-down policies were implemented. It has far-reaching implications in many sectors of life including health, particularly in patients with chronic diseases, one of which is Type-1 Diabetes Mellitus (T1DM). The purpose of this community service in the form of online gathering is to facilitate patients to ask questions and consult with pediatricians, due to the limitations of patients to consult directly due to the pandemic. Methods: Community service is conducted online for T1DM patients or their relatives on Sunday, September 26, 2021, from 12.00 - 13.30 WIB. The Community service was divided into several stages, including before, during, and after the online gathering.  The T1DM patients or their relatives are participants in this community services. The topic are types of Diabetes Mellitus, clinical presentation, disease progression, the diagnostic process, and its management therapy of type 1 diabetes mellitus. Results: The community service was attended by 54 parents of T1DM patient. The online gathering goes smoothly, without being constrained by something. During the online gathering, subjects actively participate in every session during the online gathering. Several questions were asked by the participants and answered well by the speakers. Conclusion: This community services activities allow participant to be able to ask question about their problem according to diabetes mellitus. Participants can consult online with pediatricians. This online gathering has a limited time, so participants can be divided into several breakout rooms with several accompanying pediatricians, so that the QnA session can be done optimally.

Background Type 1 diabetes mellitus (T1DM) is disease caused by the destruction of β pancreatic cells. The activation of T-lymphocyte and proliferation inhibitor are induced by protein tyrosine phosphatase non-receptor type 22 ( PTPN22 ). However, the link between PTPN22 C1858T gene polymorphism and T1DM is still controversy. This study aimed to analyse the C1858T gene polymorphism in Indonesian children with T1DM. Materials and methods This case-control study was conducted from March 2021 to May 2022 in the Endocrinology Outpatient Clinic at Dr. Soetomo Hospital and Tropical Disease Center Universitas Airlangga. Patients with controlled T1DM during the study period were included. The PTPN22 analysis used polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) method. Results Sixty-two children voluntarily participated in this study, and were equally divided into the T1DM and control groups. Most of the patients (94%, 58/62) are Javanese. This study revealed a more frequent CC genotype (9.4%) and allele-C (54.6%) polymorphism in the T1DM group, while more frequent CT genotype (100%) and allele-T (50%) polymorphism were in the control group. The C- and T-allele frequency was 54.6% and 45.4% in the T1DM group, respectively. The T1DM and control groups did not significantly differ ( p = .2381). Conclusions PTPN22 homozygous genotype-CC and allele-C polymorphisms are more frequent in patients with T1DM. However, the PTPN22 C1858T gene polymorphism did not significantly correlate to T1DM children in this study. Key Messages: The PTPN22 C1858T gene polymorphism does not significantly affect the susceptibility of T1DM in Indonesian children. PTPN22 homozygous genotype-CC polymorphism was more observed in the T1DM group; thus, this genotype may play as a risk factor for T1DM children in the Indonesian population.
