Complete resolution of corneal toxicity was observed at 3 weeks and the injections were suspended as there was no recurrence at 6 months follow-up.A 41-year-old female presented with dysgeusia, dry eyes, nyctalopia with progressive visual field constriction (due to autoimmune retinopathy) and gastrointestinal symptoms (due to ulcerative colitis). She was subsequently admitted to intensive care with a myasthenic crisis, and CT of the thorax demonstrated a thymoma.Following thymectomy and adjuvant radiotherapy, she has remained in complete remission from her ulcerative colitis and myasthenia gravis, her retinopathy has stabilised and there has been no thymoma recurrence over a 10-year postoperative period. There was a brief relapse of her dysgeusia (causing weight loss) and dry eye symptoms 3 years after her surgery, which resolved 8 months later. While the association of thymomas with paraneoplastic syndromes (PNS) is well established, it is unusual to present with multiple PNS, and some of these have only been documented in sparse case reports to date. Thymectomy played a crucial role in improvement and stabilisation of her PNS.Type 1 diabetes is typically a disease of young but can present at any age. We present a case of a 93-year-old woman who presented with 10 days history of feeling lethargic, polydipsia and decreased appetite. Her capillary blood glucose was raised at 25 mmol/L with significant ketonaemia and venous blood gas showing metabolic acidosis. She had a background of primary hypothyroidism and vitamin B12 deficiency with weakly positive parietal cell antibodies. Laboratory investigations confirmed diabetes with HbA1c of 117 mmol/mol (12.9%). In view of high clinical suspicion of type 1 diabetes, her diabetes autoantibodies were checked which showed strongly positive anti-GAD antibody with titre of >2000 IU/mL (range less then 10) confirming our diagnosis. She was treated with diabetic ketoacidosis protocol with intravenous fluids and intravenous insulin. On recovery, she was discharged home on once daily insulin with aim to self-manage diabetes with support from district nurses and to avoid hypoglycaemia.Right-sided infective endocarditis is frequently accompanied by septic pulmonary emboli, which may result in a spectrum of respiratory complications. We present the case of a 25-year-old woman diagnosed with infective endocarditis secondary to intravenous drug use. During a long and arduous hospital course, the patient developed empyema with bronchopleural fistula, representing severe but uncommon sequelae that may arise from this disease process. She was treated with several weeks of antibiotics as well as surgical thorascopic decortication and parietal pleurectomy.A 35-year-old primigravida presented with significant anxiety symptoms at 26 weeks' gestation. Symptoms were preceded by a nightmare about her upcoming labour. She developed repetitive intrusive thoughts of being trapped emotionally and physically in her pregnancy. Her symptoms were suggestive of new-onset claustrophobia associated with pregnancy, which has not been previously reported on. Her symptoms ameliorated with a combination of cognitive-behavioural therapy and pharmacotherapy (sertraline and low dose quetiapine). The later stages of pregnancy were associated with minimal symptoms and the resolution of her subjective 'entrapment'. A subsequent pregnancy resulted in similar although less severe symptomatology. No postpartum anxiety symptoms were demonstrated on both occasions. Anxiety symptoms can adversely impact both the mother and fetus, and thus correct identification and management of pregnancy-related claustrophobia improved symptomatology and functioning and allowed for earlier detection and reduced symptomatology in a subsequent pregnancy.Acute onset isolated freezing of gait (FOG) is a rare and defying diagnosis. Its pathophysiology is not yet totally understood and several brain regions seem to be involved. Postlesional FOG can help to shed light on the networks involved.We report a case of an 80-year-old woman who presented to the emergency department with acute onset impairment of gait. Her medical history was unremarkable. On neurological examination she was presented with difficulties in gait initiation, turning and progressing through narrow spaces. Her remaining neurological examination was unremarkable. Brain CT showed a subacute cortico-subcortical right parieto-occipital infarction. Acute isolated FOG due to parieto-occipital stroke was diagnosed. A structural disconnectome analysis showed that the lesion disrupted structural connections with the ipsilateral ventral striatum. This case highlights that acute onset FOG might be a consequence of a parietal cortical lesion.Giant fornix syndrome (GFS) results in chronic, relapsing conjunctivitis in elderly patients with enophthalmos and enlarged fornices, in which infectious material collects and perpetuates inflammation. A 98-year-old woman presented with persistent, bilateral, purulent conjunctivitis; corneal epithelial defects and progressive blepharospasm that did not respond to artificial tears, topical antibiotics and steroids and amniotic membrane grafts. Additional findings of deep-set orbits with enlarged upper fornices were diagnostic of GFS. Over the next 2 months, she responded to a combination of topical and systemic antibiotics, autologous serum eye drops, povidone-iodine forniceal rinses, and hypochlorous acid treatment of the eyelashes. GFS is an important diagnostic consideration in elderly patients with chronic conjunctivitis and deep-set orbits.Heminasal agenesis is an exceedingly rare congenital anomaly which is frequently associated with disorders of eye, lacrimal drainage system and face. At times, a proboscis may also be noted with this condition. Herein, we present a case of a 13-year-old boy who presented to us with heminasal agenesis with concomitant microphthalmos, leucomatous corneal opacity, blepharoptosis, dacryocystocoele and maxillary hypoplasia. The child underwent a modified transeptal external dacryocystorhinostomy with placement of a lacrimal stent. There was significant improvement of epiphora and discharged following surgery. Selleck PHA-665752 Heminasal aplasia with dacryocystocoele is surgical challenge; however, a well thought out surgical approach can yield satisfactory outcomes.Pseudomonas aeruginosa choroidal abscess is a rare condition which tends to affect patients with cystic fibrosis (CF) who have undergone double lung transplantation. Various surgical treatment strategies have been described but almost universally have had a dismal prognosis. We present a case of pseudomonas choroidal abscess in a CF patient with previous double lung transplantation who was managed with medical treatment, with intravitreal and systemic antibiotics, without surgical intervention, which led to successful resolution of the choroidal abscess, preservation of the eye and retention of vision.Stress fractures are injuries frequently seen in high-performance athletes, especially runners. In the femur, the most commonly affected locations are the femoral neck, condylar area and proximal shaft. Intertrochanteric fractures are much more common in the elderly population, especially among those with osteoporosis, but they can also be a result of high-energy repetitive mechanisms. We present a case of an intertrochanteric stress fracture in a young male runner. The diagnosis was suspected after persistent pain following his first marathon, and it was confirmed with an MRI. Operative fixation of the fracture was performed 22 days after the pain started, which allowed the patient to return to his activities, including 50 km marathon 4 months following the surgery.Because of its excellent ratio of specific to nondisplaceable uptake, the radioligand 11C-ER176 can successfully image 18-kDa translocator protein (TSPO), a biomarker of inflammation, in the human brain and accurately quantify target density in homozygous low-affinity binders. Our laboratory sought to develop an 18F-labeled TSPO PET radioligand based on ER176 with the potential for broader distribution. This study used generic 11C labeling and in vivo performance in the monkey brain to select the most promising among 6 fluorine-containing analogs of ER176 for subsequent labeling with longer-lived 18F. Methods Six fluorine-containing analogs of ER176-3 fluoro and 3 trifluoromethyl isomers-were synthesized and labeled by 11C methylation at the secondary amide group of the respective N-desmethyl precursor. PET imaging of the monkey brain was performed at baseline and after blockade by N-butan-2-yl-1-(2-chlorophenyl)-N-methylisoquinoline-3-carboxamide (PK11195). Uptake was quantified using radiometabolite-correctlites accumulated in the brain. Conclusion All 6 radioligands had good BP ND and good time stability of V T Among them, the o-fluoro, m-trifluoromethyl, and m-fluoro compounds were the 3 best candidates for development as radioligands with an 18F label.Theranostic applications targeting the gastrin-releasing peptide receptor (GRPR) have shown promising results. When compared with other peptide ligands for radioligand therapy, the most often used GRPR ligand, RM2 (DOTA-Pip5-D-Phe6-Gln7-Trp8-Ala9-Val10-Gly11-His12-Sta13-Leu14-NH2), may be clinically impacted by limited metabolic stability. Aim With the aim to improve the metabolic stability of RM2, we investigated whether the metabolically unstable Gln7-Trp8 bond within the pharmacophore of RM2 can be stabilized via substitution of L-Trp8 by α-methyl-L-tryptophan (α-Me-L-Trp) and whether the corresponding DOTAGA analogue might also be advantageous. A comparative preclinical evaluation of 177Lu-α-Me-L-Trp8-RM2 (177Lu-AMTG) and its DOTAGA counterpart (177Lu-AMTG2) was carried out using 177Lu-RM2 and 177Lu-NeoBOMB1 as reference compounds. Methods Peptides were synthesized by solid-phase peptide synthesis (SPPS) and labeled with 177Lu. Lipophilicity was determined at pH 7.4 (logD7.4). Receptor-mediated internalizearance from tumor tissue. Compared to 177Lu-AMTG, 177Lu-AMTG2 did not show any further beneficial effects. Conclusion The results of this study, particularly the superior metabolic stability of 177Lu-AMTG, strongly recommend a clinical evaluation of this novel GRPR-targeted ligand to investigate its potential for radioligand therapy of GRPR-expressing malignancies.In head and neck cancer, a major limitation of current intraoperative margin analysis is the ability to detect areas most likely to be positive based on specimen palpation, especially for larger specimens where sampling error limits detection of positive margins. This study aims to prospectively examine the clinical value of fluorescent molecular imaging to accurately identify "the sentinel margin," the point on a specimen at which the tumor lies closest to the resected edge in real-time during frozen section analysis. Methods Eighteen patients with oral squamous cell carcinoma were enrolled into a prospective clinical trial and infused intravenously with 50 mg of panitumumab-IRDye800CW 1-5 d before surgery. Resected specimens were imaged in a closed-field near-infrared optical imaging system in near real-time, and custom-designed software was used to identify locations of highest fluorescence on deep and peripheral margins. The surgeon identified the sentinel margin masked to optical specimen mapping, and then the regions of highest fluorescence were identified and marked for frozen analysis.
