Primary hyperparathyroidism commonly affects elderly women. When present in the young population, it is usually asymptomatic, most frequently due to a parathyroid adenoma and the definitive management is surgical excision. Uncommonly, 5-10% of patients fail to achieve long-term cure after initial parathyroidectomy and 6-16% of them is due to an ectopic parathyroid adenoma that will require focused diagnostic and surgical approaches. We report a 21-year-old male who had bilateral thigh pain. Work-up revealed bilateral femoral fractures, brown tumors on the arms and multiple lytic lesions on the skull. Serum studies showed hypercalcemia (1.83 mmol/L), elevated parathyroid hormone [(PTH) 2025.10 pg/mL], elevated alkaline phosphatase (830 U/L), normal phosphorus (0.92 mmol/L) and low vitamin D levels (18.50 ng/mL). Bone densitometry showed osteoporotic findings. Sestamibi scan showed uptake on the left superior mediastinal region consistent with an ectopic parathyroid adenoma. Vitamin D supplementation was started pre-operatively. Patient underwent parathyroidectomy with neck exploration; however, the pathologic adenoma was not visualized and PTH levels remained elevated post-operatively. Chest computed tomography with intravenous contrast was performed revealing a mediastinal location of the adenoma. A repeat parathyroidectomy was done, with successful identification of the adenoma resulting in a significant drop in PTH and calcium levels. Patient experienced hungry bone syndrome post-operatively and was managed with calcium and magnesium supplementation. A high index of suspicion for an ectopic adenoma is warranted for patients presenting with hypercalcemia and secondary osteoporosis if there is persistent PTH elevation after initial surgical intervention. Adequate follow-up and monitoring is also needed starting immediately in the post-operative period to manage possible complications such as hungry bone syndrome.

BACKGROUND/OBJECTIVE

Although nutritional assessment tools have been available internationally, local data for their use in foreseeing adverse outcomes among admitted patients are currently unavailable. The primary objective of this study was to determine the association of nutritional status using Short Nutritional Assessment Questionnaire (SNAQ) and malnutrition risk using the MST (Malnutrition Screening Tool) with ICU admission and in-hospital mortality.

METHODOLOGY

This was a prospective-cohort study which included 122 purposively-selected adult participants who were non-intubated, admitted for medical and surgical managements, stayed for at least 24 hours, had no COVID-19 infection, and were not admitted in any critical care unit. The SNAQ and MST questionnaires, which are validated tools and consists of  two to three easy-to-answer questions, were used among the participants and their scores were tallied in order to get their nutritional status and malnutrition risk. Primary endpoints measured were length of hospital stay, incidence of mortality, and ICU admission rate. Comorbidities were taken into account using the Charlson Comorbidity Index.

RESULT

Categorizing the SNAQ scores showed 33.61% were severely malnourished which was similar when using the MST classification, wherein 34.43% were at risk of malnutrition. None of the participants were admitted to the intensive care unit (ICU). Malnutrition risk and nutritional status was not significantly associated with 30-day in-hospital mortality (p >0.05). On the other hand, results of the Cox proportional hazards showed that SNAQ and MST significantly predicted the hazard of 30-day in-hospital mortality, increasing the hazard of mortality by 2.58 times and 3.67 times, respectively, for every 1-unit increase in SNAQ and MST scores. Similarly, nutritional status using the SNAQ classification indicated the severely malnourished category significantly predicted the hazard of mortality, increasing it by 9.22 times for those who are severely malnourished. Also, malnutrition risk using the MST classification indicated that those who were at risk of malnutrition were 9.80 times at greater hazard of mortality than those who were not at risk of malnutrition.

CONCLUSION

The MST and SNAQ classification are screening tools for nutritional status (SNAQ) and malnutrition risk (MST) that can be administered at the onset of the patient’s hospital course and have been demonstrated in this study to predict 30-day in-hospital mortality. It is important to note that none of the patients included in this study required intensive care unit admission.
