Aids em mulheres
A
prevenção da Aids em mulheres e meninas está fracassando,
diz o Fundo das Nações Unidas para a Infância
(Unicef). Para combater a desinformação, na próxima
segunda-feira a entidade lançará uma campanha para
conscientizar mulheres quanto ao contágio do HIV.
De
acordo com o Unicef, o número de mulheres africanas
infectadas pelo HIV é duas vezes maior do que o de homens.
A falta de informação é a grande vilã:
80% das jovens de países com altos índices de contaminação
não têm conhecimentos sobre a doença.
Para
a diretora executiva do Unicef, Carol Bellamy, é necessário
buscar mais métodos de prevenção da doença
entre as mulheres. Ela afirma que, em muitos lugares, as mulheres
sofrem por causa da desigualdade nos relacionamentos com os homens
e pelo fato de se sentirem incapazes de negar relações
sexuais. Segundo a Organização das Nações
Unidas, a cada 14 segundos um jovem é infectado
pelo HIV.

Médicos da Universidade de Tóquio anunciaram ter
encontrado uma maneira de combinar células-tronco com partículas
de gordura para fazer uma prótese
de seios natural.
Essas células são encontradas na medula óssea
e em outras partes do organismo humano e são responsáveis
pela produção de vários outros tipos de células.
O método poderia ser uma alternativa
aos implantes de silicone, largamente
utilizados atualmente.
A tentativa de usar gordura da própria paciente para aumentar
o tamanho dos seios falharam porque alguns tecidos morrem, formando
nódulos.
Mas os cientistas japoneses dizem,
em artigo publicado no site da revista
Nature,
que
a adição de células-tronco
poderia provocar o surgimento de novos vasos sanguíneos,
que alimentariam os tecidos.
A equipe de médicos japonesa acredita ter encontrado uma
maneira de superar essas complicações.
Durante a cirurgia, as células de gordura são aspiradas
da barriga ou das coxas. Em seguida, essa mistura é enriquecida
com células-tronco e injetada na área
dos seios.
Essas células-tronco são capazes de produzir novas
células de gordura.
O cirurgião plástico americano Adam Katz, da Universidade
da Virgínia, disse à revista Nature que existem grandes
chances de o método desenvolvido no Japão dê certo.
Ele sugere, no entanto, que sejam realizados
mais testes com animais antes de se passar
a humanos.BRITISH

Instrumental delivery makes future vaginal
delivery more likely
Instrumental vaginal delivery is
better than caesarean section for
future delivery
outcomes.
Three years
after the delivery,
Bahl and colleagues (p 311) surveyed
283 women who had had instrumental
delivery or caesarean
section.
They
found that
subsequent spontaneous
vaginal delivery was more likely
after an instrumental delivery than
after a
caesarean
section, that
fear of childbirth was
common after all types of operative
delivery, and that difficulty conceiving
was more likely after caesarean section.
Operative delivery in the second
stage
of
labour has
important implications
for future
delivery outcomes, the authors say,
and its psychological impact needs
urgent
attention.

Objective To evaluate the
reproductive outcome and
the mode of delivery
in subsequent pregnancies
after
instrumental
vaginal delivery
in theatre or caesarean section
at full dilatation.
Participants A cohort of
393 women with term, singleton,
cephalic
pregnancies who
needed
operative delivery
in theatre during
the second stage of labour
from
February 1999 to February
2000. Postal
questionnaires were received
from 283 women (72%) at three
years
after the
initial
delivery.
Main outcome measure Mode of
delivery in the subsequent
pregnancy.
Results 140 women (49%) achieved
a further pregnancy at three
years. 91/283 (32%)
women wished to
avoid a further pregnancy.
Women were
more likely to aim for vaginal
delivery (87% (47/54) v 33%
(18/54); adjusted
odds ratio
15.55 (95% confidence
interval
5.25 to 46.04))
and more likely to have a vaginal
delivery (78% (42/54) v 31%
(17/54); 9.50 (3.48
to 25.97)) if they had
had a previous
instrumental
vaginal
delivery rather than a caesarean
section. There was a high rate
of vaginal delivery
after caesarean
section
among women
who attempted
vaginal delivery 17/18 (94%).
In both groups, fear of
childbirth was a frequently
reported reason for
avoiding a further pregnancy
(51% after instrumental vaginal
delivery, 42% after caesarean
section; 1.75
(0.58 to 5.25)).
Conclusion Instrumental vaginal
delivery offers advantages
over caesarean
section for future
delivery outcomes.
The psychological impact of
operative delivery requires
urgent
attention.

Objectives To evaluate the
impact of labouring in
water during
first stage
of labour on
rates of epidural
analgesia
and
operative delivery in
nulliparous women with dystocia.
Design Randomised controlled
trial.
Setting University teaching
hospital in southern
England.
Participants 99 nulliparous
women with dystocia (cervical
dilation
rate < 1
cm/hour in active labour)
at low risk of complications.
Interventions Immersion
in water in birth pool
or standard
augmentation
for dystocia
(amniotomy
and
intravenous
oxytocin).
Main outcome
measures Primary: epidural analgesia
and operative
delivery
rates. Secondary:
augmentation rates
with amniotomy
and oxytocin, length
of labour, maternal and
neonatal morbidity
including
infections, maternal
pain score, and maternal
satisfaction
with
care.
Results Women randomised
to immersion in water
had a lower
rate of
epidural analgesia
than
women allocated
to augmentation
(47%
v 66%, relative risk
0.71 (95% confidence
interval
0.49
to 1.01), number needed
to treat for benefit
(NNT) 5).
They
showed no difference
in rates of operative
delivery (49% v 50%,
0.98 (0.65 to
1.47), NNT 98),
but
significantly
fewer
received
augmentation (71%
v 96%, 0.74 (0.59 to
0.88), NNT 4) or any
form of obstetric
intervention
(amniotomy, oxytocin,
epidural, or
operative
delivery) (80%
v 98%, 0.81 (0.67 to
0.92), NNT 5). More neonates
of
women in
the water
group were admitted to
the neonatal unit
(6 v 0, P = 0.013), but
there was no difference
in
Apgar
score,
infection
rates,
or umbilical
cord pH.
Conclusions Labouring
in water under midwifery
care
may be
an option for
slow progress
in labour, reducing
the
need
for obstetric
intervention,
and offering an alternative
pain management strategy.

Expression of CB1 and CB2 receptors
was demonstrated in human myometrium;
endogenous
and exogenous
cannabinoids exert a potent relaxant
effect on human myometrial contractility
by selective modulation of the
CB1 receptor.
Commentary
This article demonstrates one of
the ways that basic science research
can
help solve
clinical
questions.
Cannabis use during pregnancy
in some studies is
associated with an increased frequency
of premature
labor, whereas
in
other studies
this is not the case.
This study,
with its findings that
cannabis relaxes oxytocin-generated
uterine contractions,
would
favor the latter
findings. Abdominal sacral colpopexy

Sacral colpopexy and sacrospinous colpopexy are equally effective
in the treatment of vaginal vault prolapse.
Objective The purpose of this study was to compare
the abdominal
sacral
colpopexy and
vaginal sacrospinous
colpopexy
in
the treatment of
vaginal vault prolapse.
Study design Ninety-five
women with vaginal
vault prolapse
were allocated
randomly
to sacral colpopexy
(47 women)
or sacrospinous
colpopexy (48 women). Primary
outcome measurements
include
subjective,
objective, and
patient-determined success rates. Secondary
outcomes include
the impact on bowel,
bladder, and
sexual function,
cost, and quality of life.
Results Two years
after the operation
(range,
6-60 months),
the subjective
success rate
was 94% in
the abdominal
and 91% in the
vaginal group
(P=.19). The objective success
rate was
76% in the abdominal
group and
69% in the vaginal
group
(P=.48).
The
abdominal
approach was
associated with a longer operating
time,
a slower return
to activities
of daily living, and
a greater
cost
than the sacrospinous
colpopexy (P<.01). Both surgeries significantly
improved the patient's quality of life (P<.05).
Conclusion Abdominal
sacral colpopexy
and vaginal sacrospinous
colpopexy
are both
highly effective
in the treatment
of vaginal vault
prolapse.

On May
4, 2003, a US
Army soldier received
primary smallpox
vaccination and
experienced a primary
uptake reaction
at the inoculation
site on days 6
through 8.
The vaccinee
reported observing
all of the standard
precautions to
avoid household
spread. In
mid May, his breastfeeding
wife developed vesicles
on both areolas.
On May 29, their
infant daughter
developed a
papule on
her philtrum.
Contact vaccinia was confirmed
by positive
polymerase chain reaction
and culture for vaccinia
of both the maternal
and infant lesions.
This is the first
documented case of inadvertent contact vaccinia
transmission from a mother to her infant
through direct
skin-to-skin
and skin–to–mucous
membrane contact while breastfeeding. The mechanism of
transfer from the vaccinee to the spouse is uncertain.
This report demonstrates
that breastfeeding infants living in close contact with
smallpox vaccinees are at potential risk for contact
vaccinia, even if
the vaccinee is not the breastfeeding mother, and highlights
the need
for special precautions to prevent secondary transfer
to breastfeeding mothers.

Abstract
Objectives: To evaluate the pregnancy
outcome
after laparoscopic tubal
anastomosis.
Methods: From December
1998 to December
2001, 26 patients
with bilateral tubal
ligation
who underwent
laparoscopic tubal
anastomosis were prospectively
evaluated.
Patients' age varied
from 28 to
37 years. Results: Laparoscopic tubal reversal
was performed
in 23 patients. Bilateral
reversal
was possible in all
but two patients.
The operation time
ranged from
95 to 155 min and
all patients were
discharged in the
following morning
after surgery.
After 3 months,
tubal patency
was confirmed
in 15 patients (15/23).
Pregnancy rate
was 56.5% (13/23),
without ectopic
pregnancies. The average
time from
tubal reversal and
pregnancy was 6 months.
Conclusions: In
selected cases,
laparoscopic tubal
reversal can be
offered to patients
who had been submitted
to tubal sterilization
and desire
new pregnancies. Patient
selection
as well as meticulous
surgical technique
are key factors
in achieving
satisfactory pregnancy
rates.

Nipple-Sparing
Mastectomy
Reasonable Option
for Carefully Screened
Patients
CLEVELAND, OH -- February
10, 2004 -- Research
conducted at The
Cleveland Clinic
is challenging the long-held
belief
that nipple-sparing
surgery
is
not a reasonable option
for women undergoing
total breast removal.
Instead, the study
concludes that carefully
screened
patients may have
the option of undergoing
a nipple-sparing
mastectomy, which
more closely preserves
the body's natural
appearance.
Joseph
P. Crowe, M.D.,
director of the
Breast Center
at The Cleveland
Clinic, developed
the nipple-sparing
procedure
and led
the study of
54 nipple- sparing
mastectomy procedures
involving 44 Clinic
patients who were
carefully screened
and deemed eligible
for the procedure.
Results for the
study, conducted
between September
2001 and June
2003, appear
in the Feb. 9

of Surgery.
Climara
Pro (Estradiol/Levonorgestrel)
Transdermal Therapy,
to Help Alleviate
Menopausal Hot
Flashes and
Night Sweats, Now Available
in US
New
Once-A-Week Patch
Offers Effective
and Convenient Treatment
with Lowest
Estrogen Dose Available
in Combination
Therapy
MONTVILLE,
NJ --
February 10,
2004 --
Berlex, Inc.,
a U.S.
affiliate of
Schering AG,
Germany (NYSE:
SHR), announced
today that
Climara Pro™ (estradiol/levonorgestrel
transdermal system),
is now
available to
U.S. women
in pharmacies
nationwide. Climara
Pro effectively
relieves moderate
to severe
vasomotor symptoms
such as
hot flashes
and night
sweats with
the lowest
estrogen dose
of any
combined hormone
therapy in
a convenient,
once-a-week patch.
"
The availability of Climara Pro provides the thousands of U.S.
women impacted by these debilitating menopausal symptoms with a
significantly different and much-needed new option," said
Marie Foegh, M.D., D.Sc., Vice President of Medical Affairs for
Female Healthcare at Berlex. "Climara
Pro offers
effective
symptom
relief with
one-twentieth
of
the estradiol
dose of
standard oral
hormone therapy
products and
is the
first HT
to use
the trusted
progestin,
levonorgestrel."
The
transdermal technology
of Climara Pro allows
for continuous delivery
of the
hormones estradiol,
which simulates
the estrogen made
by
the ovaries (0.045
mg/day), and levonorgestrel,
(0.015
mg/day) at doses
substantially lower
than in pills,
through a thin,
translucent patch
that is easily
affixed to the
skin and virtually
invisible after
being applied. Transdermal
delivery,
unlike oral therapy,
also avoids
first-pass effects
through the
liver during absorption.
This translates
to no increase
in triglycerides
or sex
hormone
binding globulin
(SHBG).

OBJETIVO: Analisar
as
complicações maternas associadas
ao tipo de parto e comparar o parto cesáreo com o via vaginal.
MÉTODOS: Estudo retrospectivo de 1.748 partos realizados
em hospital universitário de São Paulo no período
de abril a dezembro de 2001, cujos recém-nascidos apresentaram
peso superior a 500 gramas. Foram analisadas as complicações
maternas ocorridas durante o parto e as diagnosticadas durante
o puerpério, necessitando de nova internação
da paciente. Para análise estatística, foram utilizados
o teste t de Student e o teste Exato de Fisher. Adotou-se como
nível de significância o valor de 0,05. RESULTADOS: O parto cesáreo foi realizado em 988 pacientes (56,5%) e
o por via vaginal em 760 (43,5%). As complicações
hemorrágicas ocorreram em 1,2% dos casos de cesárea
e em 0,8% dos casos de parto via vaginal, sem diferença
significativa entre esses grupos. A endometrite ocorreu em 0,4%
dos casos de cesárea e em 0,1% dos partos por via vaginal,
não sendo observada diferença significativa. Dois
casos de infecção puerperal evoluíram para
histerectomia no grupo cujo parto foi cesáreo. Não
foi observado nenhum caso de óbito materno relacionado à cesárea.
CONCLUSÕES: Não foram constatadas associações
entre as complicações maternas e o tipo de parto
no período
analisado.

ABSTRACT
Background The cause of
preeclampsia
remains
unclear. Limited
data suggest
that
excess
circulating
soluble fms-like
tyrosine kinase
1 (sFlt-1),
which
binds
placental growth
factor (PlGF)
and vascular
endothelial
growth
factor (VEGF),
may have a
pathogenic
role.
Methods We
performed
a nested
case–control
study
within
the
Calcium
for
Preeclampsia
Prevention
trial,
which
involved
healthy
nulliparous
women.
Each
woman
with
preeclampsia
was
matched
to
one
normotensive
control.
A
total
of
120
pairs
of women
were
randomly
chosen.
Serum
concentrations
of
angiogenic
factors
(total
sFlt-1,
free
PlGF,
and
free
VEGF)
were
measured
throughout
pregnancy;
there
were
a
total
of
655
serum
specimens.
The
data
were
analyzed
cross-sectionally
within
intervals
of
gestational
age
and
according
to the
time
before
the
onset
of preeclampsia.
Results During
the
last
two
months
of
pregnancy
in
the
normotensive
controls,
the
level
of
sFlt-1
increased
and
the
level
of
PlGF
decreased.
These
changes
occurred
earlier
and
were
more
pronounced
in
the
women
in
whom
preeclampsia
later
developed.
The
sFlt-1
level
increased
beginning
approximately
five
weeks
before
the
onset
of
preeclampsia.
At
the
onset
of
clinical
disease,
the
mean
serum
level
in
the
women
with
preeclampsia
was
4382
pg
per
milliliter,
as
compared
with
1643
pg
per
milliliter
in
controls
with
fetuses
of
similar
gestational
age
(P<0.001).
The
PlGF
levels
were
significantly
lower
in
the
women
who
later
had
preeclampsia
than
in
the
controls
beginning
at
13
to
16
weeks
of
gestation
(mean,
90
pg
per
milliliter
vs.
142
pg
per
milliliter,
P=0.01),
with
the
greatest
difference
occurring
during
the
weeks
before
the
onset
of
preeclampsia,
coincident
with
the
increase
in
the
sFlt-1
level.
Alterations
in
the
levels
of
sFlt-1
and
free
PlGF
were
greater
in
women
with
an
earlier
onset
of
preeclampsia
and
in
women
in
whom
preeclampsia
was
associated
with
a small-for-gestational-age
infant.
Conclusions Increased
levels
of
sFlt-1
and
reduced
levels
of
PlGF
predict
the
subsequent
development
of
preeclampsia.

Sexually
transmissible
infections

Sexually
transmitted
infections
(STIs)
are
notable
for
their
fastidious
requirements
for
transmission
and
growth
in
the
laboratory
and
for
their
high
physical
and
psychosocial
morbidity.
The
combination
of
subtle
or
absent
symptoms
and
stigma
preventing
the
seeking
of
health
care,
leaves
many
infections
undiagnosed.
The
development
of
nucleic-acid
amplification
tests
heralded
a
new
era
in
sensitive
and
robust
diagnostic
procedures
for
STIs.
Unfortunately,
many
of
these
tests
are
not
commercially
available
or
are
too
expensive
for
the
populations
that
need
them
most.
Single-dose
oral
azithromycin
has
improved
the
treatment
of
several
bacterial
STIs,
but
quinolones
are
rapidly
becoming
ineffective
for
gonorrhoea.
Self-treatment
of
genital
warts
with
podophyllotoxin
or
imiquimod
preparations
is
attractive
to
patients
and
might
be
cost
effective
for
health
services.
The
prospect
of
effective
vaccines
against
genital
papillomaviruses
in
the
near
future
is
real.
Such
vaccines
could
reduce
the
global
incidence
of
some
anogenital
cancers.
Episodic
treatment
of
genital
herpes
is
getting
easier
and
cheaper,
and
suppressive
treatment
can
reduce
transmission
to
regular
sexual
partners.
A
vaccine
against
herpes
simplex
virus
type
2
has
shown
some
limited
efficacy.
Ultimately,
better
control
of
STIs,
and
reduction
of
their
contribution
to
the
spread
of
HIV,
will
require
a
broad
health-sector
response
with
adequate
resourcing,
and
a
change
in
social
and
political
attitudes.
