About 59 % of patients delay seeking medical advice for more than one month after initial
perception of breast lesion. On average patients took (17.5 ) weeks to the first physician
visit. Common reasons for delay medical advice are summarized in Table (2).

About 64% of patients were educate(table1); however lack of breast cancer awareness &
ignorance was the leading cause for delay seeking medical advice.
In order to study more the level of cancer awareness & its symptoms among our females,
we asked our patients with breast cancer about their initial etiologic perceptions of their
breast lesions that probably result in a significant delay (Table 3). Unfortunatly, only 4%
thought of malignancy!!.

Finally a cross tabulation analysis (Table 4) showed that delay of more than one month
was significantly associated with advanced disease (P = 0.01), and bigger tumor size (P =
0.003).    However,      nodal     status   did    not    show      significant   results.

 Similar studies from other developing countries (20,25), Our data indicates that, women
with breast cancer in Erbil visit the physician rather late in the course of the disease with
more advanced disease (Table1). All the features of advanced breast carcinoma are
summarized below:-
       86.3 % of cases were more than 2cm in diameter.
       72.6 % of cases with axillary lymphadenectomy had positive lymph nodes.
       78.7 % of cases with positive lymph nodes had more than 3 nodes involved.
       35.2 % of infilterative ductal carcinoma were grade III (poorly differentiated).
       22.1 % of cases showed locally advanced disease & 4.2% of all cases showed
       skin ulceration +/or fungation.
In term of staging, more than 68 % presented in stage II and about 23% in stage III.

   Similar intravenous infusion of plasma from hypertensive patients into bioassay rabbits
induced biphasic actions particularly on blood pressure, GFR and Na+ excretion rate.
These results are tabulated in two tables, according to the diastolic blood pressure (DBP)
of hypertensive patients. Table (3) shows the cardiovascular and renal responses of
normal rabbits receiving plasma from hypertensive patients with high DBP. This plasma
caused marked and significant increases in arterial blood pressure, urine flow, Na+ and K+
excretion rates and GFR. Meanwhile, The %Na+ RFL was significantly decreased. These
effects were almost completely recovered in the second control period immediately
following the discontinuation of plasma infusion (Fig. 1).

of drug compliance along with proper use of the inhaler devices.

      This prospective study of age changes in testicular dimensions and associated
      findings in different age groups by ultrasound had been done.
 The aims of this study were;
 1. To estimate the growth of testes and epididymis with age and to compare it with
      other similar studies to know if there is any difference between our population and
      other populations, because there were no such similar studies were made in our
 2. To know the frequency of associated findings and frequency of incidental disease
      and to compare it with standard figures.
 3. To know the incidence of testicular mass and weather such study is helpful in
       early detection of testicular mass.
 For each component of these organs, testes and epididymis, the length and width of the
 testes had been studied, with the width of the head of epididymis.

          .The     high      occurrence   of        and may be there are a high percentages
cryptosporidiosis          among       young        of asymptomatic carriers ,but the
children may be due to their                        absence of reports of cryptosporidiosis
immuonological immaturity, lack of                  in this area may be because a specific

due to hygienic behavior and \or                              Such       high    incidence      of
contracting the infection from their                cryptosporidiosis         among         young

role of breast-feeding in human                     important from epidemiological and
cryptosporidiosis remains controversial             clinical point of view ,because
but did not prevent Cryptosporidium                 cryptosporidiosis is known to be a
infection in one primate model (27) .The            significant risk factor for malnutrition
results were not in agreement with the              and growth retardation in young
observations reported by (1,2,5) in rural           children, several studies have suggested
areas of Korea , the authors found that             that cryptosporidiosis is most common
adults aged 30-70 years revealed the                in children younger than two years and
highest positive rate among all age                 is      associated      with      malnutrition

groups and they attributed their finding                             .Checkly et al.      observed
to one possible reason that the active              that children with symptomatic
working population who are ready to                 cryptosporidiosis were grew less during
Cryptosporidium infection in the rural              the first month of infection than
areas is mainly older age group .Other              children without diarrhea. The effect of
possible reason for this discrepancy                asymptomatic cryptosporidiosis was
may be the genus Cryptosporidium                    less severe ,but these children also
includes so complex species and strains             gained less weight than controls did .
                 and the strains which found        Since Cryptosporidium causes severe

aged people than younger children .                 immunocompromised hosts and the
                                                    infection in such hosts may extend from
       The results also revealed no                 causing gastroenteritis to severe

prevalence rate by sex .Boys and girls              papillary stenosis (26) ,therefore
at this period of age possibly got the              identification        and    diagnosis      of
same     chance     of   exposure    to             cryptosporidiosis must be gained more
