exudates and Hypercalcemia

Calcium infusion is used after parathyroid surgery for renal hyperparathyroidism to treat postoperative hypocalcaemia. We compared a new infusion regimen to one commonly used in Malaysia based on 2003 K/DOQI guidelines.. Retrospective data on serum calcium and infusion rates was collected from 2011-2015. The relationship between peak calcium efflux (PER) and time was determined using a scatterplot and linear regression. A comparison between regimens was made based on treatment efficacy (hypocalcaemia duration, total infusion amount and time) and calcium excursions (outside target range, peak and trough calcium) using bar charts and an unpaired t-test.. Fifty-one and 34 patients on the original and new regimens respectively were included. Mean PER was lower (2.16 vs 2.56 mmol/h; P = 0.03) and occurred earlier (17.6 vs 23.2 h; P = 0.13) for the new regimen. Both scatterplot and regression showed a large correlation between PER and time (R-square 0.64, SE 1.53, P < 0.001). The new regimen had shorter period of hypocalcaemia (28.9 vs 66.4 h, P = 0.04), and required less calcium infusion (67.7 vs 127.2 mmol, P = 0.02) for a shorter duration (57.3 vs 102.9 h, P = 0.001). Calcium excursions, peak and trough calcium were not significantly different between regimens. Early postoperative high excursions occurred when the infusion was started in spite of elevated peri-operative calcium levels.. The new infusion regimen was superior to the original in that it required a shorter treatment period and resulted in less hypocalcaemia. We found that early aggressive calcium replacement is unnecessary and raises the risk of rebound hypercalcemia.

The human skeleton is the most common organ to be affected by metastatic cancer and bone metastases are a major cause of cancer morbidity. The five most frequent cancers in Malaysia among males includes prostate whereas breast cancer is among those in females, both being associated with skeletal lesions. Bone metastases weaken bone structure, causing a range of symptoms and complications thus developing skeletal-related events (SRE). Patients with SRE may require palliative radiotherapy or surgery to bone for pain, having hypercalcaemia, pathologic fractures, and spinal cord compression. These complications contribute to a decline in patient health- related quality of life. The multidimensional assessment of health-related quality of life for those patients is important other than considering a beneficial treatment impact on patient survival, since the side effects of treatment and disease symptoms can significantly impact health-related quality of life. Cancer treatment could contribute to significant financial implications for the healthcare system. Therefore, it is essential to assess the health-related quality of life and treatment cost, among prostate and breast cancer patients in countries like Malaysia to rationalized cost-effective way for budget allocation or utilization of health care resources, hence helping in providing more personalized treatment for cancer patients.

University Hospital, Kuala Lumpur, Malaysia.. To determine the incidence of hypercalcaemia in Malaysian patients with newly diagnosed tuberculosis (TB) before the commencement of antituberculosis treatment.. A prospective study of consecutive patients with newly diagnosed bacteriologically and/or histologically proven tuberculosis in our institution from September 1994 to March 1996.. Of a total of 120 patients (67 males, 53 females), 68 had pulmonary TB, nine had pulmonary and pleural TB, 18 had pleural TB without chest radiograph evidence of lung involvement, 16 had various other forms of extra-pulmonary TB and nine had disseminated TB. The mean age of the patients was 44.3 (+/-18.0) years. The mean albumin-adjusted serum calcium concentration was 2.53 (+/-0.22) mmol/l. Hypercalcaemia was present in 27.5% of the patients, but only 12% of these patients showed symptoms of hypercalcaemia. The type of TB and, in the case of pulmonary TB, the radiographic extent of lung involvement, had no effect on the serum calcium level.. Hypercalcaemia is not uncommon among Malaysian patients with newly diagnosed TB, but it is rarely symptomatic.

A retrospective six-month study of serum calcium and albumin in patients treated at the Kuala Lumpur Hospital was carried out. There were 19,291 subjects, of which the prevalences of hypocalcemia (corrected serum calcium of < or = 2.1 mmol/l) and hypercalcemia (corrected serum calcium of > 2.7 mmol/l) were 18.0% (3460 subjects) and 2.4% (468 subjects) respectively. Persistent hypocalcemia (a minimum of first two consecutive corrected serum calcium of < or = 2.1 mmol/l) was found in 408/19,291 subjects 2.1%). Serum calcium values of < 2.00 mmol/l were found in 98.5% of this group. Persistent hypercalcemia (a minimum of first two consecutive corrected serum calcium of > 2.7 mmol/l) was found in 108/19,291 subjects (0.5%) and 52/108 subjects (48.1%) had serum calcium values of > or = 3.0 mmol/l. 2902/3460 subjects (83.8%) and 313/468 subjects (66.9%) the hypocalcemia and hypercalcemia groups respectively failed to be retested (singletons). In the hypocalcemia group, 1115/2902 (38.4%) showed corrected serum calcium values of < 2.00 mmol/l), whilst 100/313 subjects (31.9%) of the hypercalcemia group had corrected serum calcium values of > or = 3.00 mmol/l. There were no significant differences between the mean corrected serum calcium between 3 age groups of the test population, namely in childhood ( < or = 65 years).

In this study we examined the incidence of hypercalcaemia among patients with tuberculosis in Malaysia. Serum calcium concentration and other calcium metabolism parameters were studied in 43 newly diagnosed tuberculous patients from the Kuala Lumpur General Hospital and the National Tuberculosis Centre. Forty-four patients admitted to the medical wards of the General Hospital, Kuala Lumpur were recruited as controls. The incidence of hypercalcaemia was found to be only 1/43 (2.3%). There was no significant difference between the mean serum calcium and other calcium metabolism parameters between the patients and the controls. Despite earlier reported incidences of 30-50%, this study showed that hypercalcaemia in tuberculosis is uncommon in Malaysia.

Fourteen cases of sarcoidosis consisting of 7 male and 7 female patients with a mean age of 42.4 years were seen at the University Hospital from 1972 to 1990. There were 10 Indians, 2 Malays, and 2 Chinese. Twelve patients had thoracic involvement. The other common disease manifestations included weight loss, arthralgia, hepatomegaly, erythema nodosum, peripheral lymphadenopathy, and hypercalcaemia. At initial presentation, the disease was in radiographic stage I, II, and III in 8, 3 and one patient respectively. The Kveim test was positive in 7 out of 9 patients. Eight patients required steroid therapy.

We describe the case of a 48 year old Indian female with hypercalcemia due to tuberculosis. She presented with symptoms of hypercalcemia and chest radiographs showed bilateral hilar lymphadenopathy with normal lung fields. The diagnosis of tuberculosis was made histologically from biopsy of the enlarged hilar nodes. Her hypercalcemia resolved following one month of anti-tuberculous treatment. The prevalence of hypercalcemia in tuberculosis has been reported to be high in western series. There is, however, a paucity of local data on the subject. The presence of 1-alpha-hydroxylase-like activity in pulmonary alveolar macrophages with resulting increased formation of active vitamin D metabolites is the postulated mechanism of tuberculosis associated hypercalcemia.
