BACKGROUND: Augmentation mastopexy in the massive weight loss population is challenging because of poor skin elasticity and lack of inframammary support. Despite several large studies of augmentation mastopexy in the literature, few data exist regarding this unique patient population. The authors examine early postoperative ptosis, implant malposition, and strategies to optimize outcomes. METHODS: A retrospective review of massive weight loss patients who underwent augmentation mastopexy from 2003 to 2011 was performed to record age, body mass index, implant characteristics, postoperative ptosis, and implant malposition...

Transient ptosis is a known complication of botulinum toxin (BoNT) injection due to inadvertent migration of toxin into the levator palpebrae superioris muscle. Currently there is no treatment available for BoNT induced ptosis. Apraclonidine hydrochloride is a topical ophthalmic solution with selective alpha-2 and weak alpha-1 receptor agonist activity that has the ability to elevate the eye lid. Apraclonidine has been used as a diagnostic test in Horner's syndrome. We evaluated the effects apraclonidine in a cohort of BoNT induced ptosis and a patient with Horner syndrome...

BACKGROUND HIV infections with concomitant immunologically-mediated disorders have been frequently described but there has been little research on the association between HIV and myasthenia gravis. MuSK myasthenia gravis coexisting with HIV is an even a rarer entity and can occur as a part of immune restoration disease. We report the case of a patient with asymptomatic HIV infection who presented with new-onset MuSK myasthenia gravis. CASE REPORT A 44-year-old African-American woman with HIV since 2004 and on highly active antiretroviral therapy (HAART) presented to the ED with complains of double vision and difficulty swallowing for 2 weeks...

The antidepressant-like effect of trans-astaxanthin, a compound present rich in algae, was evaluated through behavioral and neurochemical methods. Results showed that trans-astaxanthin treatment significantly decreased the immobility time in force swim test and tail suspension test, but did not influence locomotor activity. Trans-astaxanthin treatment did not effectively antagonize hypothermia and ptosis induced by reserpine. However, pre-treatment with para-chlorophenylalanine abolished the anti-immobility effect of trans-astaxanthin in force swim and tail suspension test...

The superior orbital fissure syndrome (SOFS) is a rare condition presenting as painful unilateral opthalmoplegia, ptosis, pupillary dilatation and anesthesia of the upper eyelid and forehead. It has been described after facial trauma. Other etiologies include infections, tumors or spontaneous hemorrhages in the retro-orbital space. Occurrence of SOFS after surgery in the skull base has not been described before. We recently encountered a case where a young female developed SOFS following surgery for cerebrospinal fluid (CSF) rhinorrhea...

Native American myopathy (NAM) is an autosomal recessive congenital myopathy, up till now exclusively described in Lumbee Indians who harbor one single homozygous mutation (c.1046G>C, pW284S) in the STAC3 gene, encoding a protein important for proper excitation-contraction coupling in muscle. Here, we report the first non-Amerindian patient of Turkish ancestry, being compound heterozygous for the mutations c.862A>T (p.K288*) and c.432+4A>T (aberrant splicing with skipping of exon 4). Symptoms in NAM include congenital muscle weakness and contractures, progressive scoliosis, early ventilatory failure, a peculiar facial gestalt with mild ptosis and downturned corners of the mouth, short stature, and marked susceptibility to malignant hyperthermia...

Heterozygous truncating mutations in ADNP are associated with a syndromic form of intellectual disability known as Helsmoortel-van der Aa syndrome. Among 17 previously reported patients with Helsmoortel-van der Aa syndrome, one patient exhibited blepharophimosis. Whether blepharophimosis represents a phenotypic expression of the ADNP mutation spectrum or a chance association remains unclear. Herein, we report another patient with a de novo truncating mutation in ADNP who exhibited a combination of blepharophimosis and epicanthal folds...

A case of giant hidrocystoma of the orbit in a 57-year-old female causing pain, epiphora and ptosis is reported. The cystic mass was totally excised as a whole. Histopathologic examination revealed eccrine hidrocystoma of the orbit. Hidrocystoma must be considered in the differential diagnosis of patients presenting with periocular masses causing pain and ptosis.

Mucormycosis is a life-threatening infection affecting patients with diabetes. It is an angioinvasive disease often resistant to treatment with a debilitating course and high mortality. Here, we report a case of a 45 year old woman with type 2 diabetes mellitus who presented to us with history of right-sided ptosis and facial palsy, and subsequently developed loss of vision and palatal palsy. She was in diabetic ketoacidosis. Nervous system examination revealed involvement of right second, third, fourth, sixth, seventh, ninth, and tenth cranial nerves, suggestive of Garcin syndrome...

The vesicular monoamine transporter 2 (VMAT2) is an integral presynaptic protein that regulates the packaging and subsequent release of dopamine and other monoamines from neuronal vesicles into the synapse. Valbenazine (NBI-98854), a novel compound that selectively inhibits VMAT2, is being developed for the treatment of tardive dyskinesia. Valbenazine is converted to two significant circulating metabolites in vivo, namely, (+)-α-dihydrotetrabenazine (R,R,R-DHTBZ) and a mono-oxy metabolite, NBI-136110. Radioligand binding studies were conducted to assess and compare valbenazine, tetrabenazine and their respective metabolites in their abilities to selectively and potently inhibit [(3)H]-DHTBZ binding to VMAT2 in rat striatal, rat forebrain, and human platelet homogenates...

Context: Pituitary stalk interruption syndrome (PSIS) is characterised by a thin or absent pituitary stalk usually in association with an ectopic posterior pituitary and hypoplasia/aplasia of the anterior pituitary. Associated phenotypes include varied ocular anomalies, hypoglycemia, micropenis/cryptorchidism, growth failure or combined pituitary hormone deficiencies. Although genetic causes have been identified, they explain only around 5% of PSIS cases. Objective: To identify genetic causes of PSIS by exome sequencing...

Lacrimal gland tumors are rare and constitute a wide spectrum of different entities ranging from benign epithelial and lymphoid lesions to high-grade carcinomas, lymphomas, and sarcomas with large differences in prognosis and clinical management. The symptoms and findings of a lacrimal gland lesion are a growing mass at the site of the lacrimal gland, including displacement of the eyeball, decreased motility, diplopia, and ptosis. Pain is the cardinal symptom of an adenoid cystic carcinoma. Radiological findings characteristically include an oval, well-demarcated mass for benign lesions whereas malignant lesions typically display calcifications, destruction of bone, and invasion of adjacent structures...

Accidental removal of the lacrimal gland is a rare complication of ptosis surgery. We report two children who underwent large unilateral levator palpebrae superioris resections (LPSr). After surgery, both patients developed dry eye. Post-operatively, the parents of both patients noticed no tears in the affected eye when their child cried. Computed tomography proved the absence of the lacrimal gland in the operated eye in both patients. Oculoplastic surgeons should pay close attention to the anatomy of the levator muscle and its proximity to surrounding tissues in order to avoid lesions on important orbital structures, including the lacrimal gland, and to avoid the development of long-term dry eye...
