Dienogest versus norethisterone acetate in management of endometrial hyperplasia without atypia.

Objectives: To compare the effectiveness of dienogest (DIE) and norethisterone acetate (NETA) regimens in the treatment of endometrial hyperplasia (EH) without atypia.

Methods: Participants were premenopausal women with irregular uterine bleeding, and endometrial hyperplasia without atypia on endometrial biopsy. Enrolled patients were randomly allocated into two groups: group I got DIE 2 mg/day (orally Visanne) for 14 days (10th to the 25th day of cycle) while group II received between the 16th and 25th day of the cycle, norethisterone acetate (NETA) 15 mg/d (orally Primolut Nor) was administered for 10 days.

Maternal Interleukin-17 and disease activity influence pregnancy outcomes in women with psoriatic arthritis and ankylosing spondylitis.

Objective: We aimed in this study to evaluate the impact of maternal interleukin -17A and the activity of the illness on pregnancy outcomes in Psoriatic arthritis (PsA) and ankylosing spondylitis (AS) patients.

Methods: This prospective cohort research was carried out on 48 Psoriatic arthritis and ankylosing spondylitis pregnant women attending the inpatient and outpatient clinics of the Rheumatology & Rehabilitation and Obstetrics & Gynecology Departments, Faculty of Medicine, Zagazig University Hospitals in Egypt and 30 apparently healthy age- and sex-matched pregnant women between January 1,2018, and December 31, 2019.

Results: The study group patients had a higher risk of preterm labour (32-36 weeks gestation) (aRR 1.

Preliminary study on anti-Müllerian hormone, antral follicle count, menstruation and lymphocyte subsets in systemic lupus erythematosus patients.

Objective: To investigate whether systemic lupus erythematosus (SLE) has a negative impact on the fertility of young women of reproductive age through SLE activity and therapy.

Methods: This retrospective case-control study was conducted in 50 patients with SLE and 50 healthy controls who fulfilled the 1997 American College of Rheumatology criteria. Anti-Müllerian hormone (AMH) levels were measured, and ovarian volume (OV) and total antral follicle count (AFC) were assessed by transvaginal sonar in patients and in healthy controls.

Does implementing a regime of dexamethasone before planned cesarean section at term reduce admission with respiratory morbidity to neonatal intensive care unit? A randomized controlled trial.

Aim: To assess the effectiveness of dexamethasone before planned cesarean section (CS) at term in reducing admission with respiratory morbidity to neonatal intensive care units (NICU).

Methods: A prospective randomized controlled trial which was conducted at an Egyptian teaching hospital. Participants at ≥38 weeks gestation who were planned to have planned CS were recruited.

Reverse breech extraction versus the standard approach of pushing the impacted fetal head up through the vagina in caesarean section for obstructed labour: A randomised controlled trial.

The objective of this study was to assess effectiveness and safety of the reverse breech extraction approach in Caesarean section for obstructed labour, and compare it with the standard approach of pushing the fetal head up through the vagina. This randomised controlled trial included 192 women. In 96, the baby was delivered by the 'reverse breech extraction approach', and in the remaining 96, by the 'standard approach'.

Depo-Provera Versus Norethisterone Acetate in Management of Endometrial Hyperplasia Without Atypia.

The objective of this study was to assess effectiveness and safety of Depo-Provera (medroxyprogesterone acetate) in treatment of endometrial hyperplasia (EH) and to compare it with norethisterone acetate (NETA) as an oral progestogen treatment. One hundred forty six women aged 35 to 50 years with abnormal uterine bleeding and diagnosed as having EH were randomized to receive either Depo-Provera, one injection every 3 months for 6 months (2 doses), or oral cyclic NETA, 15 mg daily for 14 days per cycle for 6 months. Primary outcome measure was regression of EH.

Maternal cytokines and disease severity influence pregnancy outcomes in women with rheumatoid arthritis.

Objectives: To assess the influence of maternal cytokine levels, disease activity and severity on preterm delivery, small for gestational age (SGA) and cesarean delivery in pregnant women with rheumatoid arthritis (RA).

Methods: A prospective study in 47 pregnant women with RA and 22 healthy pregnant controls. The main outcome measures were birth weight in relation to maternal serum levels of interleukin-6 (IL-6), interleukin-10 (IL-10), and RA activity and severity at three different time points: preconception and during the first and third trimesters.

A preliminary report on the impact of ¹⁸F-FDG PET/CT in the management of paediatric head and neck cancer.

Introduction: Paediatric head and neck malignancy accounts for 5% of all paediatric cancers. The choice of treatment and prediction of prognosis depend on the histological type of tumour, initial staging, evaluating treatment response and detection of early recurrence. Conventional imaging modalities have many limitations.

False-positive F-18 FDG uptake in PET/CT studies in pediatric patients with abdominal Burkitt's lymphoma.

Introduction: In pediatric patients with abdominal Burkitt's lymphoma, the involvement of the gastrointestinal tract and abdominal lymph nodes are the main presenting feature of the disease. Chemotherapy is the main treatment modality and could be preceded by surgical excision of the abdominal masses. To achieve cure or long-term disease-free survival a balance has to be struck between aggressive chemotherapy and the probability of tumor necrosis secondary to treatment complicated by acute infections, perforation or intestinal bleeding.

PET/CT image fusion error due to urinary bladder filling changes: consequence and correction.

Objective: A considerable change of urinary bladder (UB) shape in PET compared with CT in integrated PET/CT system is frequently noted. This study initially evaluated this finding with and without oral contrast (OC) use. In addition, a one bed pelvic section (PLV) repeat acquisition was investigated as a solution to this problem.

Combined rest redistribution thallium-201 SPECT and low-dose dobutamine contractility assessment in a simple and practical new viability protocol.

Objective: Rest-redistribution (RR) thallium-201 (Tl-201) imaging is commonly used for myocardial viability evaluation. Contractile reserve (CR) assessment with low-dose dobutamine (LDD) is another method that highly predicts functional recovery following revascularization. In this study, we investigate the feasibility of a new protocol that provides combined Tl-201 uptake, resting and CR functional regional myocardial information in a single examination.

Scintigraphic visualization of an epigastric sentinel node in recurrent breast cancer after lumpectomy and postoperative radiation therapy.

Sentinel node imaging and biopsy have become standard procedures for staging early breast cancer. Positive sentinel lymph node (SLN) biopsy necessitates the need for axillary lymph node dissection (ALND). Failure to visualize a sentinel lymph node in recurrent breast cancer after treatment by surgery, chemotherapy, and high-dose postoperative radiation therapy is almost the case in every patient.

Technetium-99m diphosphonate imaging of psammocarcinoma of probable ovarian origin: case report and literature review.

Technetium-99m methylene diphosphonate (Tc-99m MDP) bone scans have long been used by clinicians to diagnose osseous metastases in patients with cancer. However, in several benign and malignant diseases, notably those characterized by extensive soft tissue calcification, Tc-99m MDP may be taken up by the tumor itself. We present a case of a stage IIIC psammoma-rich low-grade serous carcinoma of the ovary, whose identity and extent of disease were first suggested by Tc-99m MDP scintigraphy.

Alternative lymphatic pathway after previous axillary node dissection in recurrent/primary breast cancer.

Objectives: The sentinel lymph node approach has almost become the standard procedure of choice in the management of patients with early breast cancer. The status of sentinel nodes, whether or not pathologically involved by cancer cells, represents those of the axillary nodes with a negative predictive value of almost 100%. If the axillary lymphatic nodal drainage is altered, alternative lymphatic pathways and accordingly sentinel node location will be changed.

Value of low-dose dobutamine addition to routine dual isotope gated SPECT myocardial imaging in patients with healed myocardial infarction or abnormal wall thickening by echocardiogram.

There is overlap in myocardial viability detection by thallium-201 uptake and contractile reserve (CR) using low-dose dobutamine (LDD). The dual isotope protocol was modified in this study by acquiring thallium-201 images using LDD to enhance viability detection in addition to coronary flow reserve assessment. One hundred twenty-four patients with coronary disease underwent gated single-photon emission computed tomographic thallium-201 imaging at rest with LDD (10 microg/kg/min) during acquisition followed by stress technetium-99m sestamibi myocardial perfusion (MP) imaging with dobutamine, adenosine, or treadmill exercise.

OBJECTIVE AND METHODS: This study was undertaken to find the role of fluorine-18-fluorodeoxyglucose (F18-FDG) in the diagnostic work-up of febrile Acquired Immune Deficiency Syndrome (AIDS) patients. Forty-seven (42 male and 5 female; mean age = 40.3 years) febrile patients with AIDS underwent imaging with F18-FDG by Dual Head Coincidence Imaging (DHCI).

Clinical Experience with Dual Head Gamma Camera Coincidence Imaging.

The authors report their experience with F-18 FDG coincidence imaging (CI) on a Dual Head Gamma Camera system employed for more than 2 years starting on August 23, 1996 within a community hospital. The latest version of this system included attenuation correction since May 1998. The problems with such systems and approaches in correcting these problems are described.

Retrospective analysis of sentinel node localization in multifocal, multicentric, palpable, or nonpalpable breast cancer.

Unlabelled: Multicentric or multifocal breast cancer is considered as one of the limitations for sentinel lymph node (SLN) localization. We did a retrospective analysis to evaluate the success rate, sensitivity, accuracy, and negative predictive values of SLN localization in multicentric or multifocal breast lesions.

Methods: Fifty-nine patients with multifocal or multicentric breast lesions proven by either fine-needle aspiration (19/59), core biopsy (39/59), or lumpectomy (8/59) underwent SLN localization.

Transient postischemic stunning evaluation by stress gated Tl-201 SPECT myocardial imaging: Effect on systolic left ventricular function.

Background: Transient postischemic stunning (TIS) has been reported in images obtained (1/2) to 1 hour after stress with technetium 99m tracers but has not been investigated in images obtained shortly after stress with thallium 201. We also quantified the global extent and severity of TIS, which has not been done previously.

Methods And Results: We evaluated 82 patients with either treadmill or dobutamine stress Tl-201 myocardial perfusion imaging.

Transient ischemic stunning of the myocardium in stress thallium-201 gated SPET myocardial perfusion imaging: segmental analysis of myocardial perfusion, wall motion and wall thickening changes.

Prolonged and persistent myocardial stunning has recently been demonstrated using technetium-99m sestamibi gated single-photon emission tomography (SPET) myocardial perfusion imaging post exercise or pharmacological stress test. In this study, we investigated the early postischemic transient myocardial stunning on early and delayed poststress thallium-201 gated SPET myocardial perfusion imaging using segmental wall motion (WM) and wall thickening (WT) analysis. A total of 1,680 segments from 84 patients' studies (53 men and 31 women, mean age 60 years) were evaluated on both early and delayed thallium-201 gated SPET treadmill exercise (59) or dobutamine stress (25) myocardial perfusion imaging.

Postchemoembolization liver abscess: findings on hepatobiliary scintigraphy.

We describe a 41-year-old man with a 1-week history of nausea and vomiting 1 month after chemoembolization of a liver metastasis. The patient subsequently became febrile and developed right upper quadrant abdominal and midback pain. Findings of initial laboratory and imaging studies (a noncontrast computed tomographic [CT] scan and ultrasound) were not remarkable.
