Liposarcomas are extremely rare in the mediastinum. They may achieve considerable size before causing any symptoms. Mediastinal liposarcomas may invade surrounding structures like the pericardium or the superior vena cava. Complete surgical excision is the optimal treatment in resectable cases. Excision of adjacent structures like the pericardium may be needed if the tumor infiltrates them. We report on a case of a giant liposarcoma of the mediastinum involving both hemithoraces and extending into the neck, which was successfully managed by complete surgical excision. 相似文献

Out of 36511 patients attending the ENT OHD of R. G,. Aur Medical Callege & Hospital. Kolkata, in one year 0.08% patients
were found tuning naspharyngeal mass. 30 cases of nasopharyngeal mass were studied. The peak incidence of nasopharyngeal mass
was in the age group between II to 20 years (40%). The incidence in males (73%) was more than females(27%). The maximum ineldence
was found among students (74%). Commonest ntuopharyngeal nuns teas antrochoanal polyp (30%). Next commlon masses were adenoids
(23%)Juvenile angwfibroma(20%) and nasophartngeal carcinoma (13%). Nasal obstruction was the main presenting symptom(83%)
followed by epistaxis (40%). 相似文献

Since the first transurethral resection of the prostate (TURP) was performed by Guyon at the Necker Hospital in Paris in 1901,
this treatment modality has replaced open prostatectomy as the procedure of choice for more than 95% of patients. TURP has
been used in surgical treatment of benign prostatic hyperplasia (BPH) and remains the gold standard treatment. Transurethral
vapor resection of the prostate (TUVRP) and holmium laser enucleation of the prostate (HoLEP) are new treatment modalities
for the treatment of BPH. Each procedure has its own advantages and disadvantages. Availability of instruments, surgical expertise,
and specific indications for a particular procedure are of utmost importance for successful outcome, with minimal morbidity.
TURP can be either monopolar or bipolar, using thin or thick loop. Bipolar TURP is associated with less bleeding and less
chances of dilutional hyponatremia. TUVRP, using a thick wedge loop, causes vaporization and resection of the prostate, and
is associated with less bleeding and short operative time. HoLEP is another effective alternative for the surgical treatment
of BPH. The holmium laser possesses the ideal combination of cutting and coagulation; however, it has a learning curve. 相似文献

After the interaction of estrogen with the ligand binding domain (LBD) of mouse estrogen receptor‐α (mERα) and hormone‐responsive elements of target genes, many nuclear proteins are recruited to regulate the expression of specific genes. Because it is not known which brain proteins interact with LBD or whether these proteins vary with age and sex, we used pull‐down assay and far Western blotting to detect five nuclear proteins of 160, 140, 87, 60, and 46 kD in the mouse brain. These interacting proteins were identified as PELP1, RIP140, PGC1α, BAF60, and ADA3, respectively. The level of PELP1, RIP140, PGC1α, and BAF60 decreased drastically in old compared with adult male mice, whereas the ADA3 level showed no significant change. PELP1, PGC1α, and BAF60 levels were lower in old male compared with female mice. Thus we report the identification and interaction of five nuclear proteins with mERα‐LBD, indicating their role in estrogen signaling and brain functions during aging. © 2009 Wiley‐Liss, Inc. 相似文献

A 27-month longitudinal study of 140 Bangladeshi mothers living in three tea gardens examined the effect of maternal factors (mother's age, number of live births, birth interval, and mother's work status) and sex of the infant on the duration and bout frequency of breastfeeding over 8-hr daytime periods. Prolonged breastfeeding of the infant was observed, but there was a sharp decline in duration of breastfeeding over the first 6 months, followed by a more gradual diminution thereafter. The feeding bouts showed a different pattern, with a more gradual decline over time. Housewives consistently showed a greater duration and bout frequency than women in paid employment as tea-pluckers. Over the first 6 months, primigravid mothers breastfed more frequently, but not thereafter. Older mothers (>35 years of age) breastfed with higher frequency during the first 2 months, but thereafter, the bout frequency decreased with increasing age of the infant. Over the 27-month study, maternal work status was the main factor associated with the duration and frequency of breastfeeding, with significantly higher frequency and duration among housewives. However, in the first 6 months after birth, there was very little difference in frequency or duration of breastfeeding between tea-workers and housewives, indicating that working mothers probably adjusted their time to breastfeed their infants before going, or after coming back, from work. 相似文献

A 50 year old man with a two month history of upper abdominal pain and a one month history of anorexia and weight loss, presented
with icterus and evidence of peritonitis. Laparotomy revealed biliary peritonitis which had been caused by a rupture of the
fundus of the gallbladder. The common bile duct was dilated and there was a large growth in the head of the pancreas with
multiple hepatic metastases. A cholecysto-jejunostomy and gastrojejunostomy were done and the patient had an uneventful recovery. 相似文献
