Infected tuboovarian hydatid cyst: a rare cause of tuboovarian abcess

Pelvic hydatid cysts, although rare, must be considered when evaluating a pelvic mass in women living in an endemic area. The pelvis may become secondarily involved as a result of a rupture of the cyst in another location or be the only localization of the disease. If the cyst becomes secondarily infected, it may mimic a tuboovarian abscess. A 49-year-old multipara was admitted to the emergency department with the complaint of fever, generalized abdominal pain and distension. Abdominal ultrasound revealed a 4 cm cystic structure in the liver and the gynecological examination was normal. The patient's abdominal pain receded spontaneously, so she was prescribed albendazole and discharged from the hospital. Ten days later, she complained of pelvic pain, pressure and vaginal discharge. The uterus and adnexa were tender on pelvic examination. Ultrasound revealed an 8 cm uniloculated cyst with free floating internal echogenities located between the bladder and the uterus. At surgery a 10 cm right-sided tuboovarian mass was present. A germinative membrane was present inside the abscess and pericystectomy with unilateral salphingo-oophorectomy was performed.     

Solitary polyps of the uncinate process

Cases of a solitary polyp of the nasal cavity are much less common than cases of massive polyposis. The most important factor in the formation of solitary polyps is the anatomic variations that result in mucosal contacts. We report the case of a patient who had bilateral solitary polyps of the uncinate process. Radiologic and clinical examinations revealed a medially bent uncinate process in the right nasal cavity and a bifid uncinate process in the left nasal cavity. These structures were the origins of the polyps.     

Epidermoid carcinoma involving the parotid gland and orbital region: case report of a rare entity

Epidermoid carcinoma (also known as squamous cell carcinoma) of the parotid gland is more prevalent among the elderly, as are other head and neck tumors. In most cases it is observed either as a nodal metastasis of a primary tumor that drains into the parotid area or as a direct extension of a tumor that has originated in the upper dermis. Primary epidermoid carcinomas arising directly from the parotid gland are extremely rare. Similarly, secondary invasion of the orbital region by a neighboring tumor is more common than primary epidermoid carcinoma of the orbit, which is also rare. In this article, we discuss the diagnosis and treatment of a rare case of epidermoid carcinoma simultaneously invading the parotid gland and the orbit.     

Investigation of vascular endothelial dysfunction in the patients with age-related macular degeneration

Purpose: This study aims to evaluate the association between age-related macular degeneration (AMD) and cardiovascular disease by using the noninvasive flow-mediated dilation (FMD) test to show endothelial dysfunction as an indicator of subclinical atherosclerosis.

Method: Participants in this study included 30?dry AMD patients, 30 wet AMD patients, and 30 healthy controls without any systemic disease, including AMD. FMD and the intima media thickness (IMT) of the carotid artery were compared between the groups.

Results: Comparison of FMD between the groups showed a 10.96% brachial artery dilation in the healthy controls, 3.99% in the dry AMD group, and 5.03% in the wet AMD group. While a significant difference was not observed between the wet and dry AMD groups, comparison of the control group to the wet and dry AMD groups yielded a significant difference. When brachial artery dilation below 7% was accepted as an abnormal FMD, 26.7% of the healthy controls, 66.7% of the dry AMD patients and 76.7% of the wet AMD patients were found to be abnormal. Similarly, while no significant difference was observed between the wet and dry AMD groups, comparison of the control group with the wet and dry AMD patients yielded a significant difference. When an IMT below 0.7?mm was accepted as abnormal, 26.7% of the healthy controls, 33.3% of the dry AMD, and 43.3% of the wet AMD were found to have an abnormal IMT. However, differences between the groups did not reach statistical significance.

Conclusions: In this study, use of the FMD test showed endothelial dysfunction among AMD patients. No significant differences were found between the dry and wet AMD patient groups.

Validity of proposed DSM-5 ADHD impulsivity symptoms in children

The American Psychiatric Association (APA) working group on Attention-Deficit/Hyperactivity Disorder (ADHD) proposed the inclusion of four new impulsivity symptoms. However, they were not included in DSM-5 due to the lack of sufficient evidence. The aim of this study is to investigate the performance of the proposed four ADHD impulsivity symptoms with respect to: (a) ADHD factor structure; (b) performance in predicting clinical impairment; (c) specificity for ADHD diagnosis and (d) best symptomatic threshold to predict clinical impairment. The sample comprised 416 children (31 ADHD subjects according to both DSM-IV and proposed DSM-5, 20 ADHD subjects according to just one diagnostic system and 365 controls) from 12 schools. Diagnoses were derived using semi-structured interviews and ADHD rating scales. Results from confirmatory factor analysis indicate that addition of the four new impulsivity items provided a slightly better factor structure if compared to models including only 18 items. Regression analyses showed that only one of the new impulsivity symptoms (impatient) was part of the list of best predictors of impairment. None of the four new impulsivity items was specifically associated with ADHD diagnosis. The best cutoff point in the hyperactivity/impulsivity dimension for predicting impairment did not change significantly. Overall, our findings suggest that the determination on how to best capture impulsivity dimension as part of the ADHD construct needs more investigation and that there is not enough evidence to include these four assessed impulsivity symptoms as part of the ADHD criteria.
