FAQ - rhabdomyosarcoma, alveolar
(Powered by Yahoo! Answers)

Could someone help, my baby was born with rhabdomyosarcoma I just need some advice and information?

He was diagnosed exactly four weeks old. They say that it is very rare for a infant like that to get it. The tumor was on his spine also which they said was in a unusual spot. My doctor said that he has not seen this case since 1973 with a baby. If there is anyone out there that has had this happen to them or have heard anything like this please contact me, any information will be helpful. I just don't know what exactly to do so I need as much advice as possible thank you.

I'm so sorry about your baby . . even though this may be rare you can still find support through the Rhabdomyosarcoma groups . . this disease can hit at any age. There are several types of this disease with the most common for children under 6 called Embryonal rhabdomyosarcoma

There is an email list group and the people there will be able to offer support and hopefully some guidance for you as you seek treatment:

How bad is the pain from Alveolar osteitis (dry socket)?

I had a wisdom tooth out today (about 6 hours ago) and am gagging for a fag.

It won't be worth it. Dry sockets are extremely painful and can also be dangerous. I've seen people who have had to have an entire half of their jaw removed because it got infected.  (+ info)

What is the position of inferior alveolar nerve and vessels in the inferior alveolar canal?

How does alveolar surface tension, compliance and airway resistance each affect pulmonary ventilation?

Very simply:
Alveolar surface tension: if too high, then alveoli have too much surfactant and do not transport oxygen well to the capillaries. If too low, then alveoli collapse and do not allow filling with air. Both will decrease ventilation

Airways resistance: if too high then airflow is reduced (think asthma). This leads to decreased absolute volume of air moving in and out of lungs, thereby reducing ventilation. If too low then the larger airways become floppy and tend to collapse with exhalation (called bronchomalacia), also decreases ventilation

Compliance: too low (noncompliant) = stiff lungs, harder to expand and contract = decreased ventilation. Too high (overly compliant) = flabby lungs = poor airflow even with full inhalation (you need some stiffness to create a venturi effect in the airways during inhalation) = decreased ventilation  (+ info)

How many Alveolar Processes are there?

I'm assuming theres one on the top jaw and one on the bottom.. but not sure!!

Also, any info. on the alveolar process is helpful. Thanks!

Ok, this is the last one "me." There are as many alveolar processes as there are teeth; in cases where wisdom teeth are present and no teeth are missing there are 32.

Here is some info on alveolar processes:

The alveolar processes of the maxilla and mandible are the bony sockets that support the teeth. The facial aspect of the anterior maxillary alveolar process presents a very thin plate of bone over the roots of the anterior maxillary teeth. This is important clinically. Injected local anesthetic solution over the root apex area diffuses readily through the thin bone to the nerves at the root apex and results in a localized anesthesia. In the fabrication of dentures the ridges of bone overlying the anterior maxillary teeth roots are simulated by "festooning."

Is there any latest method or any alternative method in the treatment of rhabdomyosarcoma?

My son who is 6 yrs old has rhabdomyosarcoma. he has had chemo therapy and radiation. Is there any other mode of treatment any alternative modes etc please let me know
dr dennis

Surgery to remove the tumor is often difficult or impossible because the tumor is usually embedded deep within the tissue, leaving it difficult to reach. If a tumor presents itself in the extremities, amputation is often necessary to improve survival.
If there is no evidence of metastasis, surgery combined with chemotherapy and radiation offer the best prognosis. Patients whose tumors have metastisized have a poor chance for long-term survival. In patients who began treatment before metastasis, the prognosis is better, although the disease has a five-year survival rate of 25% to 90% depending upon the stage at diagnosis and other factors.  (+ info)

what is the case in which the surface area of pulmonary alveolar are icreased?

the case in which surface area of pulmonary alveolar are increased that is lead to increasing in perfusion between them and blood supply

There is increasing evidence that hypercapnia improves oxygenation, although this is not predicted by the classical alveolar gas equation, which would suggest that at a given FIO2 and minute ventilation, increasing the FICO2 would reduce arterial O2. However, the effects appear to be mediated through improved V/Q matching, increased cardiac output and increased mixed venous oxygenation. Whereas beneficial effects in oxygenation are seen in multiple experimental models, these have not been mirrored in severely ill patients with ARDS. In this context, while hypercapnia per se may have effects on increasing V/Q matching and cardiac output, the effects of reduced tidal volume required to achieve hypercapnia may be counterproductive. Thus, there may be significant differences in oxygenation resulting from hypercapnia depending on how the hypercapnia is induced.  (+ info)

What's the significance of alveolar volume with regards to diffusing capacity?

My FEF25-75% (around 40%)
Low VA under diffusing capacity (78%)

Other readings appear normal

The greater the alveolar filling capacity, the more surface contact there is between the alveoli and the capillary bed allowing for greater diffusing capacity. Hope this helps.  (+ info)

What is Other Specified Alveolar And Parietoalveolar Pneum?

suggest you get a Taber's Medical Dictionary and do your own homework.  (+ info)

How is alveolar pressure and composition effected by a punctured thoracic cavity?

it simply means your lungs are going to be compressed by the enlargement of pleura. the pleura is the lining just before your lungs. if this gets filled with air(pneumothorax) or water (hydrothorax) or blood (hemothorax) then it would inflate like a balloon and exert pressure on the surrounding areas like your LUNGS.
difficulty in breathing.
if unattended, death.
this is the common case for those people who suffer from hack wounds or stabs/punctures in the thoracic area. they get well after treatment but after some time, they experience laboured breathing resulting from the blood and water balooning the pleura.
