Debulking surgery after muscular paraffin oil injections: Effects on calcium homeostasis and patient satisfaction.

OBJECTIVE: Cosmetic paraffin oil injections can lead to granuloma formation causing hypercalcemia and kidney failure. This study explores whether debulking surgery is an effective treatment for improving calcium homeostasis, inflammation and clinical symptoms. MATERIALS AND METHODS: In a retrospective study, we reviewed 33 patients undergoing debulking surgery. Changes in calcium, inflammatory markers, and renal function from baseline up to twelve months post-surgery were assessed. Patients were interviewed post-surgery. RESULTS: The patients were 34.6 years (SD 6.9) and had 1,104 grams (SD 591) of granuloma tissue removed following injection of 1,329 mL (SD 803) paraffin oil 7.9 years (SD 3.2) earlier. Seventeen patients had hypercalcemia and experienced a significant decline in ionized calcium from 1.48 mmol/L (SD 0.16) at baseline to 1.33 mmol/L (SD 0.03) at twelve months (p<0.002), although only four men (23.5%) became normocalcemic. Serum ferritin was reduced by 50% after twelve months (p=0.048). Sixteen patients were normocalcemic and had no change in calcium homeostasis but experienced a 20% drop in serum ferritin levels (p=0.025) after surgery. Fifteen patients completed all their planned surgeries within the study period and experienced a decline in serum ionized calcium (p=0.031), ferritin (p=0.011), and interleukin 2-receptor (p=0.037). A patient satisfaction survey showed that 55% of patients reported post-operative satisfaction scores of 10/10, and 59% of the patients reported reduced pain. CONCLUSION: Surgery improved calcium homeostasis in a fraction of patients, reduced inflammation and subjective symptoms such as pain and mental well-being in a patient group left with few treatment options except high-dose prednisolone.

Low-serum antimüllerian hormone is linked with poor semen quality in infertile men screened for participation in a randomized controlled trial.

OBJECTIVE: To investigate possible associations between serum antimüllerian hormone (AMH) concentration and semen quality in infertile men. Studies investigating the associations between serum AMH concentration and semen quality in infertile men have shown conflicting results. DESIGN: Infertile men were included during screening for participation in the First in Treating Male Infertility Study, a double-blinded, placebo-controlled, 1:1, single-center randomized controlled trial. SETTING: Not applicable. PATIENTS: At the screening visit, 400 participants produced a semen sample and had their serum analyzed for AMH concentration. INTERVENTION: Not applicable. MAIN OUTCOME MEASURES: Serum AMH concentration and semen quality. RESULTS: All men were stratified according to serum AMH concentrations in quartiles (Q1-Q4). Men in the lowest quartile had a lower sperm concentration (1 × 106/mL) (Q1: 8.0 vs. Q2: 10.4 vs. Q3: 11.0 vs. Q4: 13.0), total sperm count (1 × 106) (Q1: 29.1 vs. Q2: 38.2 vs. Q3: 44.4 vs. Q4: 55.7), sperm motility (%) (Q1: 41 vs. Q2: 57 vs. Q3: 50 vs. Q4: 53), and progressive sperm motility (%) (Q1: 31 vs. Q2: 44 vs. Q3: 35 vs. Q4: 40) compared with the other quartiles. Moreover, men with a sperm concentration <2 million/mL had a lower serum AMH concentration compared with men having 2-16 × 106 /mL and >16 × 106/mL (31 pmol/L vs. 38 pmol/L vs. 43 pmol/L, respectively). In accordance, men with sperm motility <20% had a lower serum AMH concentration compared with men with sperm motility 20%-42%, and >42% (31 pmol/L vs. 43 pmol/L. vs. 39 pmol/L, respectively). CONCLUSION: This study shows that low serum AMH concentration is associated with poor semen quality in infertile men, which implies that serum AMH concentration may have clinical value during the evaluation of male infertility.

High-dose vitamin D3 supplementation shows no beneficial effects on white blood cell counts, acute phase reactants, or frequency of respiratory infections.

BACKGROUND: Vitamin D has been suggested to influence the immune system, and vitamin D metabolites and the vitamin D receptor (VDR) are generated and expressed in white blood cells (WBC). Moreover, vitamin D status has been associated with incidence and prognosis of some respiratory tract infections (RTI). Therefore, we investigated the effect of vitamin D3 supplementation on WBC, acute phase reactants (APR), and the risk of developing RTIs. METHODS: A double-blinded, randomized, placebo-controlled clinical trial of 307 infertile men with multiple secondary immunological endpoints. The vitamin D3 group (n = 151) initially received 300,000 IU (7,500 µg) cholecalciferol once - followed by 1,400 IU (35 µg) daily for 150 days. The placebo group (n = 156) did not receive active ingredients. RESULTS: At baseline, stratification into clinically relevant groups of vitamin D status (< 25; 25-50; 50-75; >75 nmol/L), showed an inverse association with total leucocyte concentrations (7.0 vs. 6.0 vs. 6.0 vs. 5.5 (109/L); p = 0.007), lymphocytes (2.4 vs. 2.1 vs. 2.0 vs. 2.0 (109/L); p = 0.048), CRP (2.0 vs. 1.7 vs. 1.2 vs. 1.2 (mg/L); p = 0.037), and orosomucoid (0.82 vs. 0.77 vs. 0.76 vs. 0.70 (g/L); p = 0.015). After 150 days, no differences were detected in WBC counts or APRs between the vitamin D3 and the placebo group. However, vitamin D3 treated men had a higher prevalence of self-reported RTIs compared with the placebo group (55% vs. 39%; p = 0.005). CONCLUSIONS: High-dose vitamin D3 supplementation did not alter WBCs or APRs, but a higher prevalence of respiratory infections was observed in the vitamin D3 group. Serum 25(OH)D3 was negatively correlated with most WBCs, indicating that vitamin D status may be linked with inflammation and WBC turnover, but not an important determinant of developing RTIs.
