Objective: Calcium sulfate beads (CSBs) are biocompatible hydrophilic crystals that are used to deliver local antibiotics in periprosthetic joint infections. Hypercalcemia after placement of CSBs is uncommon and poorly understood. Methods: We present the case of a woman who presented with symptomatic hypercalcemia after placement of antibiotic-eluting CSBs. Results: A 58-year-old, Caucasian woman presented with altered mental status, respiratory failure, and septic shock 2 days after placement of antibiotic-eluting CSBs for a left prosthetic hip infection. Laboratory analysis revealed severe hypercalcemia at presentation. She had no known history of fractures, kidney stones, parathyroid, or calcium disorders. She was not on any medications that could induce hypercalcemia. She was treated with aggressive intravenous hydration and 8 doses of calcitonin. Due to impaired renal function, bisphosphonate was contraindicated. She subsequently became anuric with worsening renal failure and volume overload and the decision was made to initiate dialysis. She received 8 days of continuous renal replacement therapy followed by 2 sessions of hemodialysis which improved her serum calcium levels, mental status, and renal failure with no long-term complications. Conclusion: Hypercalcemia secondary to the placement of antibiotic-eluting CSBs is rare. Larger volumes of CSBs may contribute to hypercalcemia. In some cases, hypercalcemia can be severe and symptomatic as in the case of our patient. Serum calcium levels should be monitored frequently after placement of CSBs and managed as appropriate.

Reversible Encephalopathy

Posterior reversible encephalopathy syndrome is an encephalopathy that can be clinically characterized by headache, altered mental status and/or seizures. Neuroimaging demonstrates usually reversible bilateral subcortical vasogenic occipital-parietal edema. Exact pathophysiology remains unclear but is commonly associated with hypertension, renal failure, sepsis and use of immunosuppressive therapy. Its development in the setting of severe hypercalcemia is extremely rare. The authors report a case of posterior reversible encephalopathy syndrome in a normotensive patient with severe hypercalcemia as the only identifiable cause.

Background. Previous study had reported hypercalcemia as a frequent complication (20%) following local use of antibiotic-eluting calcium sulfate (CS) during treatment of periprosthetic joint infections (PJIs). However, whether this complication may occur in patients who receive local CS implantation for management of posttraumatic osteomyelitis (OM) remains unclear. Methods. Between April 2016 and May 2017, we included 55 patients with extremity posttraumatic OM who received local antibiotic-loaded CS therapy. Serum calcium levels were detected preoperatively and on the 1st, 3rd, and 7th postoperative days (PODs). Comparisons were performed regarding serum calcium levels among the four time points and between two different CS volume groups (≤ 20 cc group and > 20 cc group). Additionally, potential associations were examined regarding CS volume and preoperative calcium level with postoperative calcium levels, respectively. Results. Altogether 46 males and 9 females were included, with a median CS volume of 20 cc. Outcomes showed that prevalence of asymptomatic hypocalcemia was more frequent, with 16.4% before surgery and 60%, 53.8%, and 25% on the 1st, 3rd, and 7th PODs, respectively. Hypercalcemia was not found in any patients, at any time point. In addition, significant differences were identified regarding serum calcium levels among different time points, suggesting significantly decreased calcium levels on the 1st (P < 0.001) and 3rd PODs (P < 0.001) and back to near preoperative level on the 7th POD (P = 0.334). However, no statistical differences were observed regarding serum calcium levels between the two CS volume groups at any time points (P > 0.05). Moreover, no significant links were identified between CS volume and postoperative calcium levels (P > 0.05). Serum calcium levels on the 3rd (P = 0.019) and 7th PODs (P = 0.036) were significantly associated with the preoperative calcium level. Conclusions. In contrast to what had occurred in PJI patients, asymptomatic hypocalcemia appeared to be more frequent in this cohort with posttraumatic OM. Hypercalcemia may be an infrequent complication before and after local CS use for the treatment of extremity posttraumatic OM.

Abstract Introduction: The diagnosis and management of hypercalcemia in hospitalized patients can be challenging. Hypercalcemia is often associated with significant morbidity and end-organ damage which may delay a patient’s recovery. Case report: A 63-years-old female presented for evaluation of left hip pain and was found to have an infection of the prosthetic joint. Past medical history was significant for type 2 diabetes and atrial fibrillation. No known history of malignancy or excess calcium, vitamins A or D intake. Past surgical history was significant for multiple left hip fixation surgeries and a left hip arthroplasty 4 months prior. Patient’s serum calcium on admission was 8.4 mg/dL (corrected 9.5 mg/dL, range 9.5-10.5 mg/dL), serum creatinine 1.2 mg/dL (range, 0.5 - 1.2 mg/dL). Three days later, she underwent surgical irrigation and debridement of the left hip with placement of 30 cc STIMULAN® antibiotic beads with vancomycin. On postoperative day (POD) 5, patient was found to be confused. Laboratory workup revealed serum calcium 13 mg/dL, ionized calcium 1.91 mmol/L (range, 1.12-1.32 mmol/L), serum creatinine 1.6 mg/dL, intact PTH 10 (range, 15- 65 pg/mL), PTH-rp 15 pg/mL (range, 14-27 pg/mL), 25-OH-vitamin D 18 ng/mL (range, 30-60 ng/mL), 1,25-OH2-vitamin D &lt;8 ng/mL (range, 18-72 ng/mL). Clinical challenge: The differential diagnosis of non-PTH mediated hypercalcemia includes malignancy, granulomatosis and/or excess calcium intake. The patient’s history and laboratory data were not consistent with these etiologies. The temporal nature of the hypercalcemia in relation to implantation of antibiotic beads suggest causality of exogenous calcium sulfate and development of the patient’s hypercalcemia. Mild renal insufficiency, as well as immobilization in the setting of surgery, were likely also contributory. Treatment and outcome: This patient was first treated with aggressive intravenous saline and calcitonin. Serum calcium rose to 13.7 mg/dL and pamidronate 30 mg was administered. Hypercalcemia resolved on POD 11 with improvement in patient functional status. Discussion: Hypercalcemia due to implanted calcium sulfate antibiotic beads is not well described outside of case reports. Kallala found hypercalcemia in less than 0.01% of patients who underwent bead implantation, with all the affected patients presenting with preoperative renal failure. Conclusion: Hypercalcemia in the setting of calcium sulfate antibiotic beads implantation may contribute to a patient’s confusion and increase length-of-stay. We recommend serum calcium and creatinine to be closely monitored during the perioperative period in patients who receive calcium sulfate antibiotic beads. Risk factors for the development of hypercalcemia require additional study, though patients with pre-existing renal insufficiency may not be good candidates for the mechanism of antibiotic administration.

Background. A previous study had reported that patients with osteomyelitis (OM) appeared to be more likely to develop hypocalcemia before and after surgery. Calcium sulfate (CS) is frequently used as a local antibiotic vehicle in the treatment of OM, which may also affect serum calcium level. However, whether changes of serum calcium level are caused by OM and/or local use of calcium sulfate remains unclear. Also, platelet (PLT) count plays a crucial predictive role in periprosthetic joint infections (PJIs), but its role in assisted diagnosis of OM is largely unknown. The purpose of this study was to determine whether serum calcium level and PLT count may be helpful in assisted diagnosis of PTOM. Methods. Between January 2013 and December 2018, we analyzed 468 consecutive patients (392 males and 76 females), including 170 patients with posttraumatic OM (PTOM), 130 patients with aseptic bone nonunion (ABN), and 168 patients recovered from fractures with requirement of implant removal set as controls. Preoperative serological levels of calcium, phosphorus, and PLT were detected, and comparisons were conducted among the above three groups. Additionally, correlations and receiver operating characteristic (ROC) curves were displayed to test whether calcium level and PLT can differentiate patients with ABN and PTOM. Results. Outcomes showed that the incidences of asymptomatic hypocalcemia (PTOM vs. ABN vs. controls = 22.94 % vs. 6.92% vs. 8.82%, χ 2 = 21.098 , P < 0.001 ) and thrombocytosis (PTOM vs. ABN vs. controls = 35.3 % vs. 13.84% vs. 12.35%, χ 2 = 28.512 , P < 0.001 ) were highest in PTOM patients. Besides, the mean serological levels of phosphorus in PTOM and ABN patients were significantly higher than those in the controls ( P = 0.007 ). The Area Under the Curve (AUC) of the ROC curve outcomes revealed that, with the combination of serum calcium level with PLT count, the predictive role was acceptable (AUC 0.730, P < 0.001 , 95% CI 0.681-0.780). Also, serological levels of calcium of 2.225 mmol/L and PLT count of 246.5 × 10 9 / L were identified as the optimal cut-off values to distinguish patients with and without PTOM. However, age- and gender-related differences in serum calcium levels (age, P = 0.056 ; gender, P = 0.978 ) and PLT count (age, P = 0.363 ; gender, P = 0.799 ) were not found to be statistically significant in any groups. In addition, no significant correlations were identified between serum calcium level and PLT count ( R = 0.010 , P = 0.839 ). Conclusions. Asymptomatic hypocalcemia and thrombocytosis appeared to be more frequent in this cohort with PTOM. Serological levels of calcium and PLT count may be useful biomarkers in screening patients suspected of PTOM.

Severe hypercalcemia can be either acute or decompensate from a chronic state to a medical emergency, the hypercalcemic crisis. The presence of symptoms such as altered mental status or potentially fatal ECG abnormalities demand an expeditious decrease in serum calcium levels. Standard medical therapy consists of vigorous volume replacement, calcitonin and, depending on the etiology, bisphosphonates, cinacalcet or glucocorticoids. Hypercalcemic crisis is a rare indication for urgent hemodialysis and is reserved for patients with severe symptoms, ineffective medical therapy or end stage renal disease. The use of hemodialysis in this scenario is not commonly reported. We hereby report a patient who presented with altered mental status and acute kidney injury due to a hypercalcemic crisis secondary to primary hyperparathyroidism. Treatment included urgent hemodialysis to effectively lower calcium levels.

Abstract. Introduction: The use of antibiotic impregnated biodegradable synthetic high purity calcium sulfate (SHPCS) beads is frequently reported as they offer increased concentration of antibiotics locally, without need for removal. However some wound discharge following their use has been noted. The purpose of this study was to determine any correlation between wound discharge and infection remission.Methodology: Retrospective study of 39 cases of Osteoarticular infections from April 2013 to November 2016 in whom SHPCS beads were used. All patients underwent the standard staged protocol of aggressive debridement, deep tissue biopsy, implant removal where indicated and early soft tissue cover. SHPCS beads were used locally in the second stage combined with appropriate antibiotics based on tissue culture. All patients received systemic antibiotics for a period of 6 weeks and followed up for a minimum period of six months. The study analysed the patient demographics, etiology, surgical procedures, culture patterns, local antibiotics used, radiological status of beads, incidence and characteristics of wound discharge and outcome.Results: There were 25 cases of chronic osteomyelitis, eight infected non unions, three peri prosthetic joint infections, two soft tissue infections and one case of acute osteomyelitis. 17 of these infections were following osteosynthesis. The cultures were negative on eight occasions in seven patients. A total of 40 organisms were isolated in the other patients; commonest being Staphylococcus aureus (n=16) and E coli (n=7). SHPCS beads were mixed with vancomycin in 17 cases, colistin in 11, vancomycin with colistin in eight and vancomycin with gentamicin in four. Voriconazole was used in one case with fungal infection.Eight cases (20.51 %) developed discharge from the wound at an average of 6 days after inserting the beads. The discharge was serous with no foul smell in six and purulent in two inflamed wounds. Four cases underwent re-debridement; two cases with purulent discharge and subsequent positive cultures; two with serous discharge early in the series and no evidence of infection on re-exploration with negative cultures. The remaining four patients with serous wound discharge were observed without any further surgical intervention, with the discharge stopping spontaneously between 15 to 36 days post operatively. There was no correlation between antibiotic used and wound discharge. Radiographic analysis showed dissolution of all the beads at an average of 36 days in the 39 cases. Heterotrophic ossification was not observed.Clinical and radiological remission of infection was observed in 37 cases (94.9%). Two patients died during the course of hospitalization, secondary to septicaemia and multi organ failure. Three patients had an infection recurrence within six months, managed successfully by re-debridement and appropriate antibiotics. Radiological union was achieved in seven of the eight infected non unions.Conclusions: With the encouraging rates of infection remission we have observed, we continue to use antibiotic loaded SHPCS as an alternative for local antibiotic delivery in the treatment of osteoarticular infections. However, wound discharge is a known potential observation following implantation of calcium sulfate beads, subsiding typically within four to six weeks.The appearance of wound discharge can vary, ranging from purulent discharges to non-purulent, serous/ sero sanguineous fluid wound discharges. The presence of a wound discharge alone does not necessarily imply a failure to treat the infection.It is important to be aware of this side effect and guard against unnecessary re- operations, by careful consideration and monitoring all of the available clinical signs of infection, in addition to blood test results and radiographic evidence. Further research is needed to determine the relationship between the implantation of antibiotic loaded calcium sulfates and the incidence and duration of drainage.
