This study reports a rare case of broad ligament abdominal ectopic pregnancy (EP). Interventions included preoperative transabdominal and transvaginal ultrasonography and operative laparoscopy. Successful extraction of the EP, followed by suturing of the mesosalpinx, was performed. Laparoscopic fertility-preservation treatment of broad ligament EP is valuable for women during the childbearing period.

This case report describes a case of isolated (not associated with other anomalies) lower vaginal hypoplasia complicated by megalourethra (urethral dilatation) due to frequent urethral sexual intercourse in a regularly menstruating (hypomenorrheic) woman. The patient was a 24-year-old woman who underwent transperineal ultrasonography as well as magnetic resonance imaging followed by sequential cystoscopic and vaginoscopic examinations. Finally, a pull-through procedure was used to create a new vagina. The main outcome measure was patent vagina formation. The procedure successfully corrected isolated lower vaginal hypoplasia. The postoperative course was smooth, with the restoration of regular intercourse in the correct location. It was concluded that all gynecologists should have increased awareness of rare female genital anomalies to avoid serious sequelae, particularly in newly married patients.

Patients with essential thrombocythemia (ET) can undergo laparoscopy without international precautions. This case report describes an ET with a mild increase in the platelet count that developed after laparoscopic surgery and prolonged intraperitoneal bleeding. The patient underwent intensive postoperative medical and surgical treatments until cured. Patients with ET should provide informed consent for post-laparoscopic bleeding. Surgeons should perform optimal hemostasis. Further studies are required to provide clear guidelines for both medical and surgical interventions aimed at preventing thrombo-hemorrhagic complications associated with ET. A preoperative study of platelet function and the selection of the best cytotoxic drug for the perioperative period are mandatory.

This study prospective randomized controlled trial aims to test the impact of adding health education, awareness of some contributing factors and clinical guidance to therapeutic cabergoline given to infertile women with unexplained resistant hyperprolactinemia. It comprised 120 infertile women with unexplained persistent hyperprolactinemia not responding to therapeutic doses of cabergoline 1.5-2 mg/week who were subjected to proper history taking to exclude concomitant drug intake or possible brain problems in all cases. They were classified into group A (60 cases) who received health education and clinical guidance to search for possible contributing factors and were instructed to avoid them in addition to proper therapeutic doses of cabergoline, while group B (60 cases) received proper therapeutic doses of cabergoline only without clinical guidance. After 1 month, serum prolactin (PRL) was measured for all cases. All cases had high PRL level at the start of the study (79.9±28.4 [39-195] and 78.2±19.9 [42-189] in group A and B, respectively) without any significant difference. Pretreatment counselling revealed that lifestyle factors, sexual behaviors or feeding habits may contribute to resistant hyperprolactinemia in all cases without a significant difference between both groups. Serum PRL dropped significantly more in group A (20.14±10.31 [11-45] vs. 49.32±37.03 [12-100]) after combined health education, clinical guidance of the couple and proper treatment. It is concluded that lifestyle factors, sexual behaviors, and feeding habits would affect the response of hyperprolactinemia to treatment. Health education and clinical guidance with some advice to avoid them, would concomitantly improve the response of resistant hyperprolactinemia to therapeutic doses of dopamine agonists.
FREDHOLM-VOLTERRA INTEGRAL EQUATION WITH SINGULAR KERNEL
Darwish, M.A. 한국전산응용수학회 1999 Journal of applied mathematics & informatics Vol.6 No.1
The purpose of this paper is to obtain the solution of Fredholm-Volterra integral equation with singular kernel in the space $L_2(-1, 1)\times C(0,T), 0 \leq t \leq T< \infty$, under certain conditions,. The numerical method is used to solve the Fredholm integral equation of the second kind with weak singular kernel using the Toeplitz matrices. Also the error estimate is computed and some numerical examples are computed using the MathCad package.
NEIGHBORHOODS OF CERTAIN SUBCLASSES OF ANALYTIC FUNCTIONS WITH NEGATIVE COEFFICIENTS
Darwish, Hanan E.,Aouf, Mohamed K. Korean Mathematical Society 2011 대한수학회보 Vol.48 No.4
The main object of this paper is to prove several inclusion relations associated with (j, ${\delta}$)-neighborhoods of various subclasses defined by Salagean operator by making use of the familiar concept of neighborhoods of analytic functions. Special cases of some of these inclusion relations are shown to yield known results.

We study the solvability of a perturbed quadratic functional-integral equation of fractional order with linear modification of the argument. This equation is considered in the Banach space of real functions defined, bounded and continuous on an unbounded interval. Moreover, we will obtain some asymptotic characterization of solutions.
On A Subclass of Harmonic Multivalent Functions Defined by a Certain Linear Operator
Darwish, Hanan Elsayed,Lashin, Abdel Moneim Yousof,Sowileh, Suliman Mohammed Department of Mathematics 2019 Kyungpook mathematical journal Vol.59 No.4
In this paper, we introduce and study a new subclass of p-valent harmonic functions defined by modified operator and obtain the basic properties such as coefficient characterization, distortion properties, extreme points, convolution properties, convex combination and also we apply integral operator for this class.
On Certain Subclasses of Starlike p-valent Functions
Darwish, Hanan Elsayed,Lashin, Abd-el Monem Yousof,Soileh, Soliman Mohammed Department of Mathematics 2016 Kyungpook mathematical journal Vol.56 No.3
The object of the present paper is to investigate the starlikeness of the class of functions $f(z)=z^p+{\sum\limits_{k=n}^{\infty}}a_p+k^{z^{p^{+k}}} (p,n{\in}{\mathbb{N}}=\{1,2,{\ldots}\})$ which are analytic and p-valent in the unit disc U and satisfy the condition $\|(1-{\lambda}({\frac{f(z)}{z^p}})^{\alpha}+{\lambda}{\frac{zf^{\prime}(z)}{pf(z)}}({\frac{f(z)}{z^p}})^{\alpha}-1\|$ < ${\mu}$ (0 < ${\mu}{\leq}1$, ${\lambda}{\geq}0$, ${\alpha}$ > 0, $z{\in}U$). The starlikeness of certain integral operator are also discussed. The results obtained generalize the related works of some authors and some other new results are also obtained.
