Neonatal seizures: A mother's blessing in disguise.

Fetus and neonate are dependent maternal supply of calcium for maintaining the calcium profile in physiologic range. The disturbances in maternal calcium homeostasis leads to changes in the baby's calcium. Maternal investigations in neonatal hypocalcemia not only reveal the etiology in the baby but are sometime helpful in unmasking maternal disorder of calcium homeostasis.

Ten-year use of recombinant parathyroid hormone for the treatment of hypoparathyroidism in a boy with partial Jacobsen syndrome.

Pediatric hypoparathyroidism (HPT) is caused by inherited or acquired defects involving the synthesis or secretion of PTH, resistance to PTH action, or inappropriate regulation of PTH. Several syndromes such as DiGeorge syndrome, HDR (hypoparathyroidism, sensorineural deafness and renal dysplasia) syndrome, HRD (hypoparathyroidism, retardation, and dysmorphism) syndrome, Kenny-Caffey syndrome etc. may have associated HPT. In the present communication, we describe, the hitherto unreported, occurrence of HPT in a child with partial Jacobsen syndrome. Chromosomal Microarray analysis showed a heterozygous deletion of 4.7 Mb at cytoband 11q24.3q25 encompassing approximately 20 genes including JAM3 and NTM genes. The child was treated with recombinant human parathyroid hormone (rhPTH1-34) for 10 years. Throughout follow up, he required several adjustments in dosages of rhPTH1-34 and oral calcium to maintain serum calcium concentrations in low normal ranges. The bone turnover markers remained normal and oral calcium supplements were completely taken off after 8 years. In conclusion, our single-case experience indicates that long-term therapy of chronic HPT with rhPTH1-34 is safe and reduces the need for additional therapies.

Recombinant parathyroid hormone for hypoparathyroidism in children: a narrative review.

The conventional management of hypoparathyroidism in children involves the use of calcium and vitamin D analogs. This therapy effec-tively increases the serum calcium levels but worsens hypercalciuria and its consequences such as nephrocalcinosis and renal insuffi-ciency. Although replacement with the missing parathyroid hormone (PTH) is ideal and available for more than 2 decades, the reported concerns of osteosarcoma prohibited its use in children with open epiphyses. Nevertheless, the data accumulated over the past several years suggests that the fears of bone malignancies were probably overstated. With an aim to review the available data on recombinant PTH (rhPTH) use, we performed a literature search using international databases and identified 15 studies involving approximately 70 children with hypoparathyroidism due to various etiologies who received rhPTH1-34 for durations between 1 day and 13.5 years. All the studies appear to indicate that rhPTH1-34 therapy is an effective short and long-term strategy for treatment of hypoparathyroidism with better metabolic control, lesser effects on renal function and improved quality of life as compared to conventional therapy. A more significant conclusion is the safety of long-term use of rhPTH1-34 with no observed adverse skeletal effects so far. However, all studies mention the importance of a continued surveillance for adverse effects in the treated patients. This narrative review discusses the experi-ence of rhPTH1-34 use exclusively in children.

Safety and Effectiveness of Bone Marrow Cell Concentrate in the Treatment of Chronic Critical Limb Ischemia Utilizing a Rapid Point-of-Care System.

Critical limb ischemia (CLI) is the end stage of lower extremity peripheral vascular disease (PVD) in which severe obstruction of blood flow results in ischemic rest pain, ulcers and/or gangrene, and a significant risk of limb loss. This open-label, single-arm feasibility study evaluated the safety and therapeutic effectiveness of autologous bone marrow cell (aBMC) concentrate in revascularization of CLI patients utilizing a rapid point-of-care device. Seventeen (17) no-option CLI patients with ischemic rest pain were enrolled in the study. Single dose of aBMC, prepared utilizing an intraoperative point-of-care device, the Res-Q™ 60 BMC system, was injected intramuscularly into the afflicted limb and patients were followed up at regular intervals for 12 months. A statistically significant improvement in Ankle Brachial Index (ABI), Transcutaneous Oxygen Pressure (TcPO2), mean rest pain and intermittent claudication pain scores, wound/ ulcer healing, and 6-minute walking distance was observed following aBMC treatment. Major amputation-free survival (mAFS) rate and amputation-free rates (AFR) at 12 months were 70.6% and 82.3%, respectively. In conclusion, aBMC injections were well tolerated with improved tissue perfusion, confirming the safety, feasibility, and preliminary effectiveness of aBMC treatment in CLI patients.
