Floating-Harbor syndrome: case report

Floating-Harbor syndrome is a rare disorder which is clinically characterized by short stature, retarded speech development, delayed bone ages, triangular face, bulbous nose and thin lips. We described two cases with Floating-Harbor syndrome and briefly reviewed the relevant literature.     

Pediatric silicone oil surgery

PURPOSE: To evaluate clinical characteristics, surgical aspects, and visual outcomes of pediatric patients who underwent pars plana vitrectomy and silicone oil injection for complicated retinal detachment. PATIENTS AND METHODS: The records of 24 patients (25 eyes) younger than 18 years were retrospectively reviewed. All patients underwent pars plana vitrectomy and silicone oil injection for complicated retinal detachment between January 1995 and June 2004 in the Ophthalmology Department of Dokuz Eylul University, Izmir, Turkey. All patients had follow-up at or beyond 6 months. RESULTS: Nineteen (79.2%) boys and 5 (20.8%) girls were included. Mean age was 12.6 years (standard deviation, +/- 3.5; range, 5 to 17). Five eyes (20%) had blunt ocular trauma. Eleven eyes (44%) had penetrating trauma. Three eyes (12%) had high myopia. Four eyes (16%) had congenital cataract surgery. One eye (4%) had redetachment 1 month after vitreoretinal surgery performed at another clinic. One case had bilateral proliferative vitreoretinopathy with an undefined cause. The retina remained attached in 18 (72%) of 25 eyes at the final examination (17 were totally attached; 1 was partially attached). Mean follow-up was 23.4 months (standard deviation, +/- 20.5; range, 6 to 108). Postoperative visual acuity improved to 1/10 or better only in 6 eyes (24%) at the last examination. CONCLUSION: In pediatric patients with complicated retinal detachment, silicone oil injection for intraocular tamponade is an option for treatment, but visual outcome is poorer than for adults.     

Effect of intravenous administration of paracetamol on morphine consumption in cancer pain control

Objective  

The present study aimed to examine the effectiveness of intravenous administration of paracetamol added to morphine in the control of cancer pain and its possible contribution as reduction of opioid consumption and opioid-related side effects.     

Lateral frontal encephalocele associated with dysplasia of orbit,eyeball, and eyelid

A case is reported of a right lateral frontal encephalocele without communication with the midline structures and in concurrence with dysplasia of the orbit, eyeball, and eyelid.     

Relationship between chronic raised intracranial pressure and empty sella presenting hormonal disturbances

The role of intracranial pressure in the development and maintenance of the primary empty sella has been pointed out in the literature previously. The hormonal changes and clinical features have been evaluated in a 30 year-old female patient examined for a convexity meningioma and a 20 year-old patient examined for chronic hydrocephalus caused by cured meningitis. Histories and investigations revealed an empty sella turcica associated with primary amenorrhoea and delayed puberty. The removal of the convexity meningioma resulted in loss of amenorrhoea and a rise in plasma gonadotrophins. The establishment of a ventriculo-peritoneal shunt did not bring about any changes in hormonal values and clinical features except the subjective headache disappeared. The importance of consideration of intracranial causes in patients who have delayed puberty or absence of menstrual history is briefly emphasized in light of the literature. Our data also demonstrated a correlation between an increase in intracranial pressure and a deficiency of hormonal secretion by the hypophysis.     

Simultaneous idiopathic bilateral sudden hearing loss – characteristics and response to treatment

Introduction

The aetiology of sudden hearing loss is poorly defined; however, infectious, vascular and neoplastic aetiologies are presumed to be responsible. In addition, the aetiology of bilateral sudden hearing loss is also unknown.

Bisphosphonate treatment and radiotherapy in metastatic breast cancer

Patients with advanced breast cancer frequently develop metastasis to bone. Bone metastasis results in intractable pain and high risk of pathologic fractures due to osteolysis. The treatment of breast cancer patients with bone metastases requires a multidisciplinary approach. Radiotherapy is an established treatment for metastatic bone pain. It may be delivered either as a localized low dose treatment for localized bone pain or systemically for more widespread symptoms. Bisphosphonates have been shown to reduce morbidity and bone pain from bone metastases when given to patients with metastatic bone disease. In vivo studies indicate that early bisphosphonates administration in combination with radiotherapy improves remineralization and restabilization of osteolytic bone metastases in animal tumor models. This review focused on a brief discussion about biology of bone metastases, the effects of radiotherapy and bisphosphonate therapy, and possible mechanisms of combination therapy in metastatic breast cancer patients.     

Assessment of orbital blood flow velocities in retinopathy of prematurity

The purpose of this study is to evaluate whether the presence of any stage retinopathy of prematurity (ROP) alters central retinal artery (CRA) and ophthalmic artery (OA) blood flow parameters in premature infants. The patients were divided into two groups according to the development of ROP; those who have ROP were defined as group I, those without ROP were defined as group II. Ninety eyes of 45 patients in group I and 40 eyes of 20 patients in group II were investigated. The blood flows in the CRA and OA were measured using ultrasound color doppler imaging (CDI) that allows to evaluate the peak systolic velocity (PSV), end diastolic velocity (EDV), and resistivity index (RI). The results were compared between two groups of subjects. There were no significant differences in the PSV, EDV, and RI of CRA between two groups (P = 0.09, P = 0.20 and P = 0.63, respectively). The mean PSV value of OA in group I was found to be significantly higher than the one in group II (P < 0.05), but there were no significant differences in the mean EDV and RI values of OA between two groups (P = 0.40, P = 0.17 respectively). The subgroup analysis revealed that the ocular blood dynamics were not found to be significant between eyes with stage I ROP and eyes with stage II ROP (P > 0.05), whereas the difference in the mean PSV values of OA were found to be significant among the eyes with stage 1 ROP, eyes with stage 2 ROP, and eyes without ROP (P = 0.03). This study demonstrated significant alterations in systolic flow velocities in the OA predicted by CDI in infants with ROP.
