Metformin -Its dynamics on suppression of hyperandrgenaemia

 

 Metformin -Its dynamics on suppression of hyperandrgenaemia

Are we at SE Asia , sub optimally utilizing the overall benefits of metformin in hyperandrogenic PCO women ??  Tthe non-carbohydrate actions  of metformin in PCO women ?  Several data suggest that metformin does counteract  on hyperandrogenism by interfe­ring both with direct and specific mechanisms on peripheral androgen-secreting organs and with free androgen fraction-regulating systems.

Metformin, acroding to them has many beneficial effects in PCO women which are still unexplored. It (metformin) is far from just an promoter of glucose entrance in cells.

In fact, many a researchers in last two decades have claimed that metformin  exerts followings in addition tomaking her euglycemic  :--

  A) It  reduces ovarian androgens

B)  it reduces adrenal secretion of androgens,

C)  it reduces pituitary secretion of LH, and

D) Metformin independently increases liver SHBG production.

All such actions are independent of beneficial effects of glucose entry  !!  All these taken together make Metformin as an important adjunct drug if we believe that PCO  is  principally a hyperandrogenic disorder of any etiology.  There seem to be still  many other  mechanisms that is  mediated by  met­formin in the face  on hyperandrogenism .

The research on the misc effects of metformin which  is a relatively new concept  is limited . I believe the reason is that assay of insulin and bioactive androgens  are usually non available  to clinicians. As such scanty studies have been undertaken by clinicians

CPP-Chronic Pelvic Pain

 

Chr Pelvic pain (CPP) where all possible noninvasive tests have been done but no definite cause could be established with certainly in such cases in  absence of  palpable pelvic pathology (T O Mass) / subfertility problem one can offer trail of medl tr of endometriosis before invasive  procedure is approved (   diagnostic laparoscopy) .It also happens albeit rarely that Opinions of Urologist, Orthopedic surgeon and Colorectal surgeon have been taken but  no definite cause could be established.

 Put under such circumstances can we prescribe Dienogest or say other drugs specifically designed as medical managements of endometriosis like B) Danazol B) Gn RH agonist C) Progesterone 

Let us see what Gambone JC1Mittman BSMunro MGScialli ARWinkel CAChronic Pelvic Pain/Endometriosis Working Group doctors opine in 2002??

Fertil Steril. 2002 Nov;78(5):961-72.

Consensus statement for the management of chronic pelvic pain and endometriosis: proceedings of an expert-panel consensus process.

.

For women in whom endometriosis is the suspected cause of the pain, laparoscopic confirmation of the diagnosis is unnecessary, and a trial of medical therapy, including second-line therapies such as danazol, GnRH agonists, and progestins, is justified provided that there are no other indications for surgery such as the presence of a suspicious adnexal mass.

  Committee Opinion 1  : When surgery is necessary, laparoscopic approaches seem to offer comparable clinical outcomes to those performed via laparotomy, but with reduced morbidity.

Committee Opinion 2 :-The balance of evidence supports the use of adjuvant postoperative medical therapy after conservative surgery for CPP.

Committee Opinion 3 :There is some evidence that adjuvant presacral neurectomy adds benefit for midline pain, but currently, there is inadequate evidence to support the use of uterosacral nerve ablation or uterine suspension.

Committee Opinion 4 : Hysterectomy alone has undocumented value in the surgical management of women with endometriosis-associated CPP.

Rh factor -The discovery of Rh factor in the human RBC and its terminology

 Rh factor -The discovery of Rh and its terminology

Rh:-Point 1:-There are total  45  blood group system (including ABO system) of which Rh is one. Rh system .Therefore Rh is  one of forty-five known human blood group systems.

 Point 2: The Rh blood group system again consists of 49 defined subgroups group antigens. However for clinicians it is sufficient to be familiar with  common  five antigens D, C, c, E, and e . These antigens are the most important. We know that there is no d antigen. and Rh negative refer to the Rh(D) antigen only.

 Antibodies to Rh antigens can be involved in hemolytic transfusion reactions and antibodies to the Rh(D) and Rh(c) antigens confer significant risk of hemolytic disease of the fetus and newborn.

 

Mistake 1:--The term "Rh" was originally an abbreviation of "Rhesus factor." It was so named as such group first  was discovered in 1937 by Karl Landsteiner and Alexander S. Wiener, who, at the time, believed it to be a similar antigen found in rhesus monkey red blood cells only  which was found later to be not true. .

Mistake 2: It was subsequently learned the human factor is not identical to the rhesus monkey factor. Thus, notwithstanding it is a misnomer, the term survives (e.g., rhesus blood group system and the obsolete terms rhesus factorrhesus positive, and rhesus negative – all three of which actually refer specifically and only to the Rh D factor and are thus misleading when unmodified.

 Mistake got corrected by  Philip Levine and Rufus Stetson:-à  

The first rhesus blood type as mentioned earlier was discovered in 1937 by Landsteiner and Wiener, who named it after a similar factor found in rhesus monkey blood. The significance of the discovery was not immediately apparent and was only realized in 1940, after subsequent findings by Philip Levine and Rufus Stetson.  

It was recognized that the Rh factor was just one in a system of various antigens. Based on different models of genetic inheritance, two different terminologies were developed; both of them are still in use.

Cytomegalovirus (CMV)

 

Cytomegalovirus (CMV)

 

Cytomegalovirus (CMV)

 Overall approximately 1% to 2% of all newborns are CMV infected, about half due to primary infection during pregnancy and the other half due to reactivation of a prior infection.Cx can shed CMV virus !!! It is now known to virologists that intermittent CMV shedding from the cervix and other body sites is quite possible if CMV remains in host body as an dormant state and not cleared after primary infection .  In such situations as CMV being a  herpes family virus –Can  Pap have some kind of reflection by exhibiting some  specific cytological changes due to CMV excretion via endocervix?? ??

At the present moment we don’t have any idea about abnormal cytology by HPV or else it is due to other kind of Herpes family. Food for thought . Surprisingly, the great majority of CMV infections are asymptomatic and we are aware of the fact that presence of activation of dormant virus  can be identified only by prospective antibody testing.

 

After primary CMV infection, virus replication may persist for many months and can be reac­tivated months or years later, with intermittent CMV shedding from the saliva, tears, urine, faeces, cervix and other sites. AS it is (CMV) is secreted via saliva / tears therefore viral spread can occur by direct body contact amongst the family members. The presence of IgM-specific CMV antibody cor­relates quite well with infection. Immunoglobulin M antibody is detected with about 90% of primary infections; however, it may also appear with recurrent infections. CMV IgG avidity testing may be of value in assessing a patient's likelihood of recent infection .

Matter of great concern for obstetricians and Neonatologists too . !!!

Surprise 1:- How many of us believe that CMV (which is a virus of Herpes family like varicella, E B Virus ) after causing an primary infection i the host , quite often remains alive in the host in as an dormant state and can be an potential source of reactivation and cause maternal illness and more importantly foetal harm ?

Surprise 2: Can such state of reactivation occur in case of T Gondii also ?

Surprise 3 : What , according to will be best drug for acute Cytomegalovirus infection if serologically confirmed after a brief maternal illness in nonpregant state when CMV IgM is strongly positive. .

Surprise 4 : Is it true that maternal immunity against CMV does ensure guarantee against prevention of vertical transmission of CMV in 70% only?

Surprise 5: Avidity tests facility often unavailable in small towns.

Surprise 5 : Like Covid we still dont have vaccination against CMV and also against Toxo infections. .Members views and worry about these two organisms which attack pregnant women often silently !!!

Multicystic ovatirs should be stimualted by HMG only

 

 Multicystic ovaries  should be stimulated by HMG only :::  Selection of Ovulogen (ovulation stimulation /Ovulation accelerating agent in cases of oligo ovulation ). 

How to do that ?? 

An ultrasound assessment of ovarian volume and AFC in the early follicular phase has been used as a predictor for ovarian response before IVF treatment, even n letrozole tr if woman concerned ins elderly , because a low AFC and  with small-volume ovaries usually indicate reduced ovarian reserve

With experience, one can recognise in the ovary three distinct morphological appearances: A) normal, B)  polycystic and C).. multicystic. I am right my dear members ? Your opinion pl?

 

 

Type C: What is Multicystic ovaries? Ans: Multicystic ovaries are characteristically observed in pubertal girls and women recovering from weight-loss-related amenorrhoea. These multicystic (or multifollicular) ovaries are A) normal in size or slightly enlarged and

 B)  contain six or more cysts that are 4-10 mm in diameter ; in contrast to women with polycystic ovaries (PCOs),

 C) the stroma is not increased.

Etilogy & pathogensis of multicystic ovaries??  The multicystic ovary appears to develop as a consequence of reduced hypothalamic secretion of GnRH, resulting in subnormal stimulation of the ovaries by the gonadotropins.

Treatment of multicystic ovaries?? Ans: The multicystic ovary has a normal response to exogenous stimulation, by either pulsatile GnRH or gonadotropins, and the ultrasound appearance of the ovary usually reverts to normal. As such t will not be wise to go ahead with letrozole straightway without such basal scan .In this case of multicystic ovaries Letrozole nor CC will work. Only HMG will work or else one can add HMG on day3, day 5,& day 8 HMG 75 IU in addition to CC/Letrozole.

TVS -- The relevance of Transvagianl sonography ??

 

 TVS   -- The relevance  of Transvagianl sonography ?? Like to have some informations on Ultrasound : Any non-emergent  pelvic scan (elective scan ) à with the idea to diagnose any pelvic tumour, small ovarian endometriomata, TO mass should be done  following  principle which may be of help : Please correct me if I am wrong because I too have no training  in sonology :Here we go : How to do Basal Scan-& what to record the findings at Basal scan. Then taken together along with endocrine evaluations in subfertility problem one can plan the treatment of subfertility: - Here we go on ABC of Pelvic Ultrasound.

 

Point 1: Abdomen first : When first scanning the pelvis, many radiologists suggest per­forming a transabdominal scan  first  to obtain an overview of the pelvic organs, and second to assess the kidneys and renal tract if indicated.

Point 2: She is requested to void urine and then , a transvaginal ultrasound examination of the pelvic is systemically done.    To visualize the pelvic  organs TVS is preferred to the transab­dominal approach as it not only obviates the need for a full bladder with its associated discomfort but also allows high-frequency probes (5-7.5 MHz) to be used so that higher resolution and greater precision in measurements or measurements of the pelvic structures, follicular diameters(AFC in particular)  and endometrial thickness be achieved. It is especially advantageous in patients who are undergoing assisted conception as they commonly have lower abdom­inal scars that impair the penetration of ultrasound.

 

Furthermore, periadnexal adhe­sions may tether the ovaries deep in the pelvis and limit the elevation of these structures that normally occurs when the bladder is filled for a transabdominal scan. If only TAS done then such adhesive lesions May be missed so aso difficult to visualize ovaries.

 

In  a recent study it was observed that  the follicles were more sharply defined in 90% of cases when the transvaginal approach was used compared with only 41% with a transabdominal approach . The same study found that the numbers and sizes of the dominant follicles correlated better with the serum oestradiol concentrations when transvaginal scanning was used.

Sonoembryology : Neorological development of foetus

 

 . Foetal neurosonoembryology What is meant by HDlive USG??  Ans: This is an extraordinary sonological imaging by which  photographs received of the imaged foetus . It appears and looks like that foetus is just standing or lying in front of  maternal abd and there is no barrier of mat abd ,liquor amnii  or placenta between the observer and foetal image. That is the term coined is HDlive USG. Gone are the days when USG meant only sonographic metrics and different diameters and volumes of organs be it maternal or foetal.

HDlive USG is an extraordinary imaging methodology which receives and processes quality photographs of foetus. This however, has of late is a most debated topic among clinicians and academics.

Sonogentics and diagnosing of Foetal Neurological Development is possible to assess now intranatally :- Foetal neurosonoembryology can pick up by HDlive silhouette  USG & Sonoangiogram by   silhouette / HD live flow technology for ventricular imaging of brain are also just possible.                                                                                                                                                                                                                                                                                                 

 

Even the cognitive function of foetal  brain can be assessed by advanced (not traditional) - 4-D- USG Magnetic Resonance  Spectroscopy for detection of metabolic changes in  foetal brain in FGR fetuses  and due to all these detailed informations and that is why  this methodology   is gaining importance!!!
