Polands Syndrome essays

Polands Syndrome essays There is a rare and perplexing congenital condition known today as Polands Syndrome. This extremely unusual disorder that is present at birth falls very near and dear to my heart. I will explain in later paragraphs. An anatomy student by the name of Alfred Poland made the first documented observation in 1841 at Guys Hospital in London. Alfred Poland discovered this extraordinary and unexplored abnormality while dissecting the cadaver of a convict that was hung for murder. The description Alfred Poland first provided was that of a congenital thoracic anomalies involving the pectoralis major and pectoralis minor with additional abnormalities on the affected side of the body (ipsilateral) consisting of webbed or fused phalanges (syndactyly). The term Polands Syndactyly was used to describe this disorder until 1967 when Baudinne renamed it, Polands Syndrome. It was felt that the condition would be more accurate if referred to as a syndrome because there were many anomalies then just syndactyly. Today, the laymens definition of Polands Syndrome consists of a developmental disorder that is present at birth. It is characterized by the absence or underdevelopment of chest muscles (pectoralis major, pectoralis minor) and abnormally short, webbed fingers or absence of middle phalanges. Additional finding might include underdeveloped or absence of one nipple or breast on the affected side. More extreme cases exhibit upper underdeveloped ribs and or an abnormally short arm with underdeveloped forearm bones. Unfortunately the limitation of Polands Syndrome deformity doesnt always cease here. The medical society has documented isolated cases over the past 100 years of chest wall disfigurement, lung herniation and spine curvature. Abnormalities involving the clavicle, scapula, kidney, testes, heart and associated occurrences of leukemia were also o ...

Infertility and Treatment Essay Example | Topics and Well Written Essays - 1000 words

Infertility and Treatment - Essay Example Further it is also estimated that about 40% of infertility cases are due to some disorder in male partner, 40% involve a female factor, and the remainder involves both sexes. In women, problems can arise with either or both of gametogenesis and fertilization. As a result of these factors it can reduce or abolish the chances of pregnancy. Statistics suggest that ovulation failure either due to absent or infrequent menstrual cycles accounts for 20% of reported cases of difficulty in conception. Other problems that prevent conception in women include blockage of fallopian tubes, polycystic ovarian syndrome, hypothalamic dysfunction, luteal dysfunction, premature menopause, etc. Blockage of fallopian tubes: Female infertility due to blocked fallopian tubes can be detected by a simple technique called the hysterosalpingography. In this process a radio-opaque dye (methylene blue) is infused into the uterus. If the leakage of dye into the abdominal cavity is noticed through the X-ray diagnosis, then it indicates open tubes, where as if the dye is remaining in the uterus and does not indicate any spillage into the abdominal cavity indicates blocked tubes. Blocked fallopian tubes can result from scarring and adhesions due to infections such as chlamydia and gonorrhea that cause pelvic inflammatory disease (PID). In general, simple surgery can clear blockages in the fallopian tube. However, if the procedure is not successful, then in vitro fertilization is recommended procedure. IVF is a procedure in which oocytes are harvested from the ovaries and fertilized by spermatozoa in a dish containing a sterile nutrient solution. It is also possible that tubes get damag ed due to previous ectopic pregnancies. Even in such cases IVF is an option. Disorders of ovulation: Ovulation disorders include amenorrhea, lack of menstrual cycles, and oligomenorrhea, infrequent cycles. Two types of medication are used in case of ovulation disorders. Clomiphene citrate which is an anti-oestrogenic drug that stimulates the anterior pituitary to release FSH is the first set of treatment. If clomiphene treatment does not work, injections of FSH are given. These drugs are administered to stimulate ovulation and help in achieving pregnancy. Polycystic ovarian syndrome (PCOS): It is the most common cause of ovulation failure in women today. The ovaries typically contain numerous small immature follicles. PCOS can be easily detected through blood tests which measure hormone levels. It is more common in women under 30 years old and is due to an abnormal production of LH and FSH. The basic imbalance of these hormones in the women's body prevents the ovaries from releasing an egg each month. It also results in an abnormally high production of the male hormone testosterone by the ovaries. As a result of this there is increase of facial hairs. A combination of weight losing exercises and hormone treatments can help the patients with PCOS to conceive. Premature menopause: Menopause is a natural phenomenon occurring in women after a certain age. Premature excessive loss of oocytes results in premature menopause in approximately 2% of teenagers and women in their early 20s. In such cases, infertility can be overcome by IVF using donated eggs. Additionally the infertile recipient of the embryos takes oestrogen and progesterone to prepare her uterus for implantation of the embryo. Medical sciences has
