Effect of intra-ovarian platelet rich plasma in women with poor ovarian response.

Background: Poor ovarian responder (POR) women, whose ovarian response to gonadotropin stimulation has decreased, are at higher risk of unsuccessful in-vitro fertilization (IVF). Therefore, this study designed to evaluate the effect of intra-ovarian platelet rich plasma (PRP) on POR women.

Methods: This single-arm trial research was done on 20 POR women referred to the IVF Unit, university-based hospital, Tehran, Iran between October 2020 and September 2021.

Effect of different alcoholic-alkaline treatments on physical and mucoadhesive properties of tapioca starch.

Alcoholic-alkaline treatment (AAT) is a physical modification method for the production of granular cold water swelling starch and should be optimized for each starch source. The main objective of this research was to investigate physical and mucoadhesive properties of tapioca starch (TS) modified by different AATs. Improvement of cold-water absorption, solubility, rheological properties at low temperatures, clarity, freeze-thaw stability, and mucoadhesion was positively correlated with the alkali amount and reaction temperature and negatively correlated with ethanol content.

Effect of acetic acid on physical properties of pregelatinized wheat and corn starch gels.

Pregelatinized starches are physically modified starches with ability to absorb water and increase viscosity at ambient temperature. The main purpose of this study was to determine how different concentrations of acetic acid (0, 500, 1000, 10,000 mg/kg) can affect functional properties of pregelatinized wheat and corn starches (PGWS and PGCS, respectively) produced by a twin drum drier. With increasing acetic acid following changes occurred for both samples; cold water solubility (at 25 °C) increased, water absorption and apparent cold water viscosity (at 25 °C) reduced, the smooth surface of the starch particles converted to an uneven surface as confirmed by scanning electron microscopy, cohesiveness, consistency and turbidity of the starch gels reduced while their syneresis increased.

Association of children's obesity with the quality of parental-child attachment and psychological variables.

Aim: This study aimed to investigate the association of children's obesity with parental attachment and psychological variables as impulsivity, self-control and efficiency of eating control.

Methods: This cross-sectional study was conducted among 202 obese students aged 9-13 years selected by multistage cluster sampling from different areas of Isfahan, Iran. Three questionnaires were considered to be answered by the students and one for their parents.

[Pulmonary sequestration detected by ultrasound].

Pulmonary sequestration is part of the spectrum of bronchopulmonary foregut anomaly. It is a rare type of congenital malformation in which a mass of pulmonary tissue is separate from the normal lung and receives its arterial supply directly from the systemic circulation. Angiographic demonstration of a systemic artery leading to the sequestrated lung has usually been used to diagnose this condition.

[Endoscopic drainage of pancreatic pseudocyst: endoscopic cysto-enterostomy].

Pancreatic pseudocysts occur in 20% of cases of chronic pancreatitis. Spontaneous resolution is seen in about 9% of the cases, but most cysts persist and frequently cause complications, such as compression of adjacent organs or infection. Endoscopic cysto-enterostomy has recently been reported as a new nonsurgical invasive approach.

Septic thrombosis of the cavernous sinus: diagnosis with the aid of computed tomography.

A case of septic cavernous sinus thrombosis is described which was observed with high resolution computed tomography (CT). The significant CT findings in cavernous sinus thrombosis (CST) include irregular filling defects within a widened enhancing cavernous sinus. Concomitant findings are unilateral or bilateral swelling of the orbital soft tissues and sinusitis.

Intermittent superior caval venous syndrome due to permanent transvenous electrode.

A 75-year-old man began suffering from intermittent episodes of superior caval venous syndrome, seven years after implantation of an endocardial pacemaker via the right cephalic vein. The obstruction of the superior caval vein was confirmed by venography and computed tomography of the chest. Changes of the intrathoracic pressure were considered to be the mechanism responsible for the intermittence of the syndrome.

Craniofacial fibrous dysplasia complicated by mucocele: the role of radionuclide scintigraphic methods in the diagnosis.

A rare case of craniofacial fibrous dysplasia complicated by mucocele is described. Pre-surgical diagnosis was assisted by blood-pool scintigraphy and bone scanning, with special emphasis on the vertical skull view. Other noninvasive methods like x-rays and cranial computed tomographic scans are also illustrated.

Short-term thrombosis after transvenous permanent pacemaker insertion.

In order to assess prospectively the incidence and significance of venous thrombosis early after permanent transvenous pacemaker implantation venographic studies were carried out in 40 consecutive patients. The venograms performed between 1 and 6 months (mean 4 months) after the implantation were normal in 31 patients (77%), in six patients (15%) they showed partial venous obstruction and in three patients (8%) total obstruction. Between 6 and 12 months (mean 9 months) the venograms of five patients, that were previously normal, showed partial venous thrombosis.

Exogastric neurilemmoma presenting as acute abdomen: role of computed tomography in diagnosis.

A case of subserosal gastric neurilemmoma is hereby presented. This reported case is unique in its clinical presentation including the appearance of acute abdomen and fever subsequent to unremarkable and uneventful upper gastrointestinal endoscopy. The tendency of neurilemmoma to cause mucosal ulceration with fistula formation probably led to this clinical presentation.

Multiple ophthalmic anomalies and digital hypoplasia.

Multiple congenital eye and hand anomalies occurred in a young female born to normal but consanguineous parents. Both eyes were microphthalmic with severe corneal, iris lens pathology. Ultrasonography revealed multiple echos from the vitreous.
