Hyperthyroidism in a complete molar pregnancy with a mature cystic ovarian teratoma.

BACKGROUND: The hallmark of gestational trophoblastic disease is the production of human chorionic gonadotropin (hCG) due to the hyperproliferation of extraembryonic trophoblast cells. Previous studies show hCG has thyrotropic action due to its structural similarity with thyroid stimulating hormone (TSH) molecules. Germ cell tumors represent 15-20% of all ovarian tumors and can be malignant or benign. CASE PRESENTATION: We present a case of a 53-year old African American female with a history of hyperthyroidism secondary to a complete hydatidiform mole and an associated finding of a mature cystic ovarian teratoma. She presented with nausea, vomiting, nervousness, weight gain, abdominal pain and a b-hCG of greater than 450,000mIU/mL. A total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed and curative for her symptoms. Lung nodules were noted with slight increases in b-hCG levels in the months following the surgery. Propranolol and methimazole were used to treat the acute hyperthyroid symptoms. CONCLUSION: This case presents the rare occurrence of a complete hydatidiform mole causing hyperthyroidism and an associated finding of a mature cystic teratoma. It also highlights the importance of monitoring b-hCG levels following a complete molar pregnancy due to an increased risk of choriocarcinoma.

Predictors of colonization with Staphylococcus species among patients scheduled for cardiac and orthopedic interventions at tertiary care hospitals in north-eastern Germany-a prevalence screening study.

As methicillin-resistant Staphylococcus aureus (MRSA) colonization and infection in humans are a global challenge. In Mecklenburg and Western Pomerania (Germany) 1,517 patients who underwent surgical interventions were systematically screened for MRSA and MSSA colonization on the day of hospital admission and discharge. Demographic data, risk factors and colonization status of the (i) nose, (ii) throat, (iii) groin, and (iv) thorax or site of surgical intervention were determined. Of the 1,433 patients who were included for further evaluation, 331 (23.1%) were colonized with MSSA, while only 17 (1.2%) were MRSA carriers on the day of hospital admission. A combination of nose, throat and groin swabs returned a detection rate of 98.3% for MSSA/MRSA. Trauma patients had lower prevalence of MRSA/MSSA (OR 0.524, 95% CI: 0.37-0.75; p < 0.001) than patients with intended orthopedic interventions. Males showed significantly higher nasal S. aureus carrier rates than females (odds ratio (OR) = 1.478; 95% CI: 1.14-1.92; p = 0.003). Nasal S. aureus colonization was less frequent among male smokers as compared to non-smokers (chi2 = 16.801; phi = 0.154; p < 0.001). Age, gender and smoking had a significant influence on S. aureus colonization. Combining at least three different swabbing sites should be considered for standard screening procedure to determine S. aureus colonization at patients scheduled for cardiac or orthopedic interventions at tertiary care hospitals.

Bartonella quintana endocarditis of the tricuspid and mitral valves.

Bartonella quintana is a gram-negative microorganism that can lead to culture-negative infective endocarditis (IE) in immunocompromised patients. Here, we present an exceptionally rare case of a 70-year-old male with Bartonella quintana-associated IE primarily limited to the tricuspid valve that spread to the mitral valve after tricuspid valve replacement. This was then complicated by infective spondylodiscitis of the thoracic vertebrae, ultimately resulting in death due to cardiac arrest.
