FK506 (tacrolimus) is an immunosuppressive drug and more potent than cyclosporine. FK506 is widely used for immunosuppression in the prevention and treatment of graft-versus-host disease after allogeneic bone marrow transplantation and solid organ transplantation. Neurotoxicity is a recognized complication of FK506 therapy, but ptosis and weakness of eye abduction unilaterally has not been reported in association with FK506 administration to date. We discuss a 13-year-old male patient who developed ptosis and weakness of eye abduction unilaterally 90 days after transplantation with bone marrow from an unrelated donor, for acute lymphoblastic leukemia in this case report...

PurposePREPL deficiency causes neonatal hypotonia, ptosis, neonatal feeding difficulties, childhood obesity, xerostomia, and growth hormone deficiency. Different recessive contiguous gene deletion syndromes involving PREPL and a variable combination of SLC3A1 (hypotonia-cystinuria syndrome), CAMKMT (atypical hypotonia-cystinuria syndrome), and PPM1B (2p21 deletion syndrome) have been described. In isolated PREPL deficiency, previously described only once, the absence of cystinuria complicates the diagnosis...

AbstractAlthough specific antivenom is available in Taiwan, respiratory failure and general pain frequently accompany Bungarus multicinctus envenomation and there have been few reports on the management of B. multicinctus envenomation. We retrospectively analyzed 44 cases of B. multicinctus bite admitted to Taichung Veterans General Hospital (VGH) or to Taipei VGH. Demographic data, treatment, and outcome of patients with and without respiratory failure were compared. In this study, 20.5% patients had bites without noticeable signs or symptoms of significant envenoming, 27...

BACKGROUND: Prostaglandin analogs (PGAs) are commonly used to treat glaucoma because of their powerful intraocular pressure lowering effect. However, various periorbital changes associated with the use of PGAs have been reported. We investigated the incidence of periorbital changes in Korean patients who were treated with PGAs, and analyzed clinical factors associated with superior sulcus deepening. METHODS: This study included 58 glaucoma patients who were treated with latanoprost, travoprost, or bimatoprost unilaterally...

INTRODUCTION: A case of life threatening envenoming by a wild specimen of the inland taipan, Oxyuranus microlepidotus, is described. There have been 11 previously well-documented envenomings by O. microlepidotus, but only 2 were inflicted by wild snakes. Envenomed patients have presented predominantly with defibrinating coagulopathy and neurotoxicity. CASE REPORT: The victim was seeking to observe members of an isolated population of this species and was envenomed while attempting to photograph an approximately 1...

X-linked myotubular myopathy (XLMTM), a severe congenital myopathy, is caused by mutations in the MTM1 gene located on the X chromosome. A majority of affected males die in the early postnatal period, whereas female carriers are believed to be usually asymptomatic. Nevertheless, several affected females have been reported. To assess the phenotypic and pathological spectra of carrier females and to delineate diagnostic clues, we characterized 17 new unrelated affected females and performed a detailed comparison with previously reported cases at the clinical, muscle imaging, histological, ultrastructural and molecular levels...

RATIONALE: Nivolumab (Nivo) is an immune checkpoint inhibitor that has been used to treat advanced melanoma, nonsmall cell lung carcinoma, and renal cell carcinoma since 2015. Nivo is associated with several side effects, including hepatitis, pneumonitis, acute renal failure, endocrine disorder, and other immune-related adverse events. Here, we describe the case of a 65-year-old man with squamous cell lung carcinoma who developed myasthenia gravis (MG) after a third Nivo infusion. PATIENT CONCERNS: A 65-year-old man with advanced squamous cell lung carcinoma developed ptosis, diplopia, drop head, and general weakness 5 days after a third Nivo infusion...

Breast cancer is the most common female cancer in Western populations, affecting 12.5% of women, with 1.38 million patients per year. Breast-conserving surgery followed by postoperative radiotherapy replaced the radical and modified-radical procedures of Halsted and Patey as the standard of care for early-stage breast cancer once the overall and disease-free survival rates of breast-conserving surgery were demonstrated to be equivalent to those of mastectomy. However, excision of >20% of breast tissue, low or centrally located cancer, and large-sized breasts with various grades of breast ptosis, result a in unacceptable cosmetic outcomes...

Forkhead box L2 (FOXL2) is a transcription factor, which is involved in blepharophimosis, ptosis, and epicanthus in versus syndrome (BPES), premature ovarian failure (POF), as well as almost all stages of ovarian development and function. FOXL2 has various target genes, which are implicated in numerous processes, including sex determination, cell cycle regulation and apoptosis and stress response regulation in mammals. However, studies regarding the upstream regulation of FOXL2 are limited. In the present study, the promoter of FOXL2 was successfully cloned and registered in Gen Bank, and a dual luciferase reporter (DLR) analysis demonstrated that the luciferase activity was significantly induced by the promoter of FOXL2...

A 74-year-old woman, who developed advanced colon cancer with focal recurrence, received two courses of a low dose of nivolumab. Five days after the second course she noticed bilateral ptosis. Her symptoms rapidly progressed to generalized manifestations including limb and neck weakness, dyspnea, and myalgia within the following two weeks. Neurological and laboratory findings supported the diagnosis of myasthenia gravis and myositis induced by nivolumab. The combination immunotherapy including oral prednisolone, intravenous immunoglobulin and plasma exchange with noninvasive positive-pressure ventilation successfully avoid tracheal intubation...

Skin-sparing (SSM) and nipple-sparing (NSM) mastectomies are relatively new conservative surgical approaches to breast cancer. In SSM most of the breast skin is conserved to create a pocket that facilitates immediate breast reconstruction with implant or autologous graft to achieve a quality cosmetic outcome. NSM is closely similar except that the nipple-areola complex (NAC) is also conserved. Meta-analyses indicate that outcomes for SSM and NSM do not differ from those for non-conservative mastectomies. Recurrence rates in the NAC after NSM are acceptably low (0-3...

Myasthenia gravis (MG) is a disease of autoimmunity with variable and diverse clinical presentations. The target tissue is neuromuscular junction of skeletal muscles, where efficient nerve impulse transmission is hampered leading to less effective muscle contraction. Patients of MG usually present with bilateral ptosis, diplopia and fatigability, which may or may not coexist with generalised weakness, dysphagia and dysarthria. A46-year male presented with unilateral ptosis and diplopia. Except for unilateral moderate ptosis and restriction of extraocular movements, ocular and systemic examination was normal...
