A few months ago, my fiancé and I, after much consideration, decided to stop using condoms and rely only on the Pill as a contraceptive method. Since then, when he ejaculates inside my vagina, I frequently experience a strong burning sensation a few minutes afterward ? varying in both degree and length each time. Could I be allergic to his semen? The pain sometimes subsides if I hold a wet clot...

Two dozen were liberated in his garden and soon afterward a number turned up in Tuc...

n 1664, the first anatomically correct depiction of the sympathetic nervous system came from Thomas Willis and his circle of London anatomists, 1 included in The Anatomy of the Brain and Nerves, 1664 (Figure 1). This, the first work dedicated completely to the nervous system, also described the arterial loops at the base of the brain, which we now know as the Circle of Willis. 1 Christopher Wre...

The sympathetic nervous system has been implicated in pain associated with painful diabetic neuropathy. However, therapeutic intervention targeted at the sympathetic nervous system has not been established. We thus tested the hypothesis that sympathetic nerve blocks significantly reduce pain in a patient with painful diabetic neuropathy who has failed multiple pharmacological treatments. The di...

At the age of 53, a 65-year-old man had been diagnosed with extra-adrenal pheochromocytoma in the retroperitoneum and underwent total tumorectomy. Afterward, he had his serum catecholamine periodically measured in an outpatient clinic. In February 1999, 12 years after surgery, he complained of lower left abdominal pain. Computed tomography and magnetic resonance imaging revealed an osteolytic l...

lectin binding histochemistry was performed on the developing sympathetic ganglionic cells to investigate the distribution and density of defined carbohydrate terminals on the cell surface glycoproteins during autonomic system morphogenesis. sprague-dauley rat embryos from 9th gestational day to birth were fixed and paraffinized. serial sections of these specimens were incubated with different ...

room and the examining rooms of the clinic there is a small swinging gate upon which are printed the words, "NO ADMITTANCE." The boy noticed this sign and remarked, "Mother, it says there, 'No admittance.' How are we going to get in?" This remark showed of course that the boy, not yet six years old, could read, and it probably showed more. Perhaps he was too young in experience to understand th...
