Case report: Death caused by multi-organ metastatic calcifications as a result of intramuscular injections with paraffin oil.

In this forensic case report, we present autopsy findings from a young male in his thirties who had been self-injecting paraffin oil into his upper extremities 8 years prior to death. The injections induced an inflammatory response, leading to granuloma formation. This, in turn, resulted in severe hypercalcemia. The external autopsy examination revealed gross macroscopic ulcerations and enlargement of upper extremities, while calcifications of ligaments, heart, kidneys and dura mater was revealed on postmortem CT-scans. Histopathological examination showed extensive multiorgan metastatic calcifications in several tissues including the lungs, heart and kidney. Cause of death was estimated to be the extensive calcific deposits in the heart likely resulting in cardiac arrest. To our knowledge this is the first case reporting findings from an autopsy in which the cause of death was linked to cosmetic oil injections.

Ovarian follicular fluid levels of phthalates and benzophenones in relation to fertility outcomes.

BACKGROUND: Many endocrine disrupting chemicals (EDCs), for instance phthalates and benzophenones, are associated with adverse fertility outcomes and semen quality parameters. OBJECTIVE: To evaluate if concentrations of selected phthalate metabolites and benzophenones measured in follicular fluid are associated with fertility outcomes (i.e., reproductive hormones, antral follicle count, detected heartbeat at gestational week 7, and live birth) and, in a supplementary study, if measured concentrations of chemicals in follicular fluid can exert biological effects on human spermatozoa. METHODS: Overall, 111 couples from a fertility clinic in Denmark contributed with 155 follicular fluid samples. Concentrations of 43 metabolites from 19 phthalates and phthalate substitutes and six benzophenones were measured in follicular fluid using liquid chromatography-tandem mass spectrometry. Multiple linear and logistic regression with an applied generalized estimating equation model allowing more than one measurement per woman assessed the association between follicular EDC levels and fertility outcomes. The assessment of biological effects of individual and mixtures of EDCs on human spermatozoa was conducted through a human sperm cell based Ca2+-fluorimetric assay. RESULTS: Benzophenone-3 (BP-3) and seven metabolites of five phthalates were detectable in follicular fluid. Women with metabolites of dibutyl phthalate isomers in the highest tertiles had lower antral follicle count (MiBP: ß = -5.35 [95 % CI: -9.06; -2.00], MnBP: ß = -5.25 [95 % CI: -9.00; -2.00]) and lower odds for detecting a heartbeat at gestational week 7 (MiBP: OR = 0.35 [95 % CI: 0.14; 0.91], MnBP: OR = 0.39 [95 % CI: 0.13; 1.15]). Mixtures of the measured concentrations of BP-3 and the seven phthalate metabolites induced a small significant increase in the intracellular calcium ion concentration in human spermatozoa from healthy donors (n = 3). DISCUSSION: Phthalate metabolites and BP-3 were detectable in follicular fluid and high concentrations of some phthalate metabolites were linked with lower chance of successful fertility treatment outcomes. Chemical mixture concentrations in follicular fluid induced a calcium response in human spermatozoa highlighting possible biological effects at physiologically relevant concentrations.

Gynaecomastia in 786 adult men: clinical and biochemical findings.

OBJECTIVE: Gynaecomastia is a benign proliferation of glandular tissue of the breast; however, it is an important clinical observation because it can be the first symptom of an underlying disease. Some controversy exists concerning the clinical importance of an in-depth investigation of men who develop gynaecomastia. We hypothesise that a thorough work-up is required in adult men with gynaecomastia. DESIGN: All adult men (n = 818) referred to a secondary level andrological department at Rigshospitalet in Copenhagen, Denmark during a four-year period (2008-2011) under the diagnosis of gynaecomastia (ICD-10: N62) were included. METHODS: Thirty-two men who did not have gynaecomastia when examined were excluded; leaving 786 men for final analyses. They underwent an andrological examination, ultrasound of the testicles and analysis of endogenous serum hormones levels. RESULTS: In 43% of men with adult onset of gynaecomastia (≥18 years) an underlying, and often treatable, cause could be detected. In men younger at onset an underlying cause for gynaecomastia could be detected in merely 7.7%. The study is limited by the fact that we did not have access to investigate men who were referred directly by their GP to private clinics for plastic surgery or who sought cosmetic correction without consulting their GP first. CONCLUSIONS: Our study demonstrates the importance of a thorough examination and provides a comprehensible examination strategy to disclose the underlying pathology leading to the development of gynaecomastia in adulthood.

Human semen quality in the new millennium: a prospective cross-sectional population-based study of 4867 men.

OBJECTIVES: Considerable interest and controversy over a possible decline in semen quality during the 20th century raised concern that semen quality could have reached a critically low level where it might affect human reproduction. The authors therefore initiated a study to assess reproductive health in men from the general population and to monitor changes in semen quality over time. DESIGN: Cross-sectional study of men from the general Danish population. Inclusion criteria were place of residence in the Copenhagen area, and both the man and his mother being born and raised in Denmark. Men with severe or chronic diseases were not included. SETTING: Danish one-centre study. PARTICIPANTS: 4867 men, median age 19 years, included from 1996 to 2010. OUTCOME MEASURES: Semen volume, sperm concentration, total sperm count, sperm motility and sperm morphology. RESULTS: Only 23% of participants had optimal sperm concentration and sperm morphology. Comparing with historic data of men attending a Copenhagen infertility clinic in the 1940s and men who recently became fathers, these two groups had significantly better semen quality than our study group from the general population. Over the 15 years, median sperm concentration increased from 43 to 48 million/ml (p=0.02) and total sperm count from 132 to 151 million (p=0.001). The median percentage of motile spermatozoa and abnormal spermatozoa were 68% and 93%, and did not change during the study period. CONCLUSIONS: This large prospective study of semen quality among young men of the general population showed an increasing trend in sperm concentration and total sperm count. However, only one in four men had optimal semen quality. In addition, one in four will most likely face a prolonged waiting time to pregnancy if they in the future want to father a child and another 15% are at risk of the need of fertility treatment. Thus, reduced semen quality seems so frequent that it may impair the fertility rates and further increase the demand for assisted reproduction.
