Primary hyperparathyroidism presenting as severe hypercalcemia with acute pancreatitis in pregnancy

Abstract

Primary hyperparathyroidism presenting first time with severe hypercalcemia is rare in pregnancy. We report a case of primary hyperparathyroidism due to a cystic parathyroid adenoma presenting as severe hypercalcemia with acute pancreatitis in second trimester of pregnancy. Acute pancreatitis was managed by conservative treatment. Hypercalcemia failed to respond to medical management and ultimately responded to ultrasound-guided ethanol ablation of parathyroid adenoma. The delivery was uneventful and patient continues to remain normocalcemic during follow up. As such, ethanol ablation of parathyroid adenoma may be considered during pregnancy in case of failure of response to medical management and when surgical removal of parathyroid adenoma is not safe.     

Predictors of Stress Among Parents in Pediatric Intensive Care Unit: A Prospective Observational Study

Objective

To determine the sociodemographic and clinical factors leading to stress among parents whose children are admitted in pediatric intensive care unit (PICU).

Methods

A prospective observational study was conducted in PICU of a tertiary care hospital of north India. Parents of children admitted to PICU for at least 48 h duration were eligible for participation. At the end of 48 h, parental stress was assessed using parental stress scale (PSS:PICU) questionnaire which was administered to the parents. Baseline demographic and clinical parameters of children admitted to PICU were recorded. The parental stress was compared with demographic and clinical characteristics of children using appropriate statistical methods.

Results

A total of 49 parents were finally eligible for participation. Mean (SD) parental stress scores was highest in domains of procedures [1.52 (0.66)] and behavior and emotional [1.32 (0.42)] subscales. Mean (SD) total parental stress score among intubated children [1.31 (0.25)] was significantly more than among non intubated children [0.97 (0.26)] (p?p?=?0.15) and socioeconomic status (p?=?0.32). On subscale analysis, it was found that professional communication is a significant stressor in age groups 0–12 mo [0.61(0.41)] (p?=?0.02). It was observed that parents of intubated children were significantly stressed by the physical appearance of their children (p?p?=?0.008) and impairment in parental role (p?=?0.002). Total parental stress score had a positive correlation with PRISM score (r?=?0.308).

Conclusions

Indian parents are stressed maximally with environment of PICU. Factor leading to parental stress was intubation status of the child and was not affected by gender or socio demographic profile of the parents.     

The Effect of Water Absorption on Acrylic Surface Properties

PURPOSE: The aim of the present study was to determine whether an increased water content during thermal cycling of hot water-treated acrylic was associated with a reduction in surface hardness and an increased opacity or whitening of the surface. MATERIALS AND METHODS: Ten acrylic samples were treated with 30 soak cycles (cycle duration, 24 hours), using warm water (40 degrees C) and an alkaline peroxide tablet (Efferdent control group); a further ten samples were treated with boiling water (100 degrees C) and one Efferdent tablet (experimental group). Indentation hardness of the acrylic specimens was measured prior to and immediately following the completion of the warm and hot water treatments, using an automated micro-indentation system. The hydrated acrylic specimens were then allowed to air dry at room temperature (20 degrees C) and were weighed weekly until they had obtained a constant dry weight. The loss in weight of the acrylic specimens represented the maximum water absorption. RESULTS: The hot water-treated specimens were much whiter than the warm water-treated specimens. The mean reduction in hardness (H(IT)) of the acrylic specimens following the treatment with hot water and alkaline peroxide tablet was 12.9%. Treatment with warm water and alkaline peroxide resulted in a slight increase in mean hardness (2.63%). There was a significant correlation between the water content of the acrylic specimens after treatment and the percentage of change in indentation hardness (r= 0.495, p= 0.026). CONCLUSIONS: The hot water treatment of the acrylic was associated with a significant reduction in hardness. We attribute the whitening and reduction in the hardness of the hot water-treated specimens to absorption of water and a disruption of the acrylic surface structure.
