Primary leiomyosarcoma of the breast is an extremely rare neoplasm accounting for less than 0.0006% of all breast malignancies, with fewer than 80 cases reported in the literature to date. Here, we present a case of leiomyosarcoma of the breast in a 61-year-old woman without traditional risk factors. This case was treated with lumpectomy requiring wide margins due to the high rate of local recurrence. A planned breast reduction surgery was deemed adequate postlumpectomy therapy to prevent cancer recurrence, negating the need for chemotherapy or radiation therapy. To our knowledge, this is the first case in which cosmetic breast reduction surgery will be used as postlumpectomy cancer recurrence risk mitigation for primary leiomyosarcoma of the breast. Patients with this malignancy have a relatively poor prognosis compared with other breast cancer types, with a 5-year disease-free survival of 33%-52%. As such, frequent follow-up and monitoring for postresection recurrence is essential.We report a 35-year-old female patient with a history of bilateral salpingectomy from ectopic pregnancies presenting with a positive serum beta-human chorionic gonadotropin (bhCG) result following in vitro fertilisation (IVF) treatment. Apart from per vaginal spotting, she remained asymptomatic. Initial ultrasound showed an empty uterus with a cystic mass on the right side of the uterus. Serum beta-hCG was trended. A follow-up pelvic ultrasound 1 week later showed a live pregnancy in the right adnexa. A diagnostic laparoscopy was performed, which revealed an unruptured right stump ectopic pregnancy that was successfully removed. As a stump ectopic pregnancy can be a potentially life-threatening occurrence, we emphasise caution with salpingectomy and the consideration of tubal stump ectopic pregnancies following IVF treatment.A 57-year-old man with mild haemophilia B was admitted for coronary artery bypass graft surgery. His factor IX (FIX) activity was 15% on admission. Our goal was to maintain his FIX activity at 80%-100% for post-op days (PODs) 0-3, and at 60%-80% for PODs 4-14. Preoperatively, the patient was given recombinant FIX (rFIX) bolus using the formulaDosage needed=%(desired FIX level-current level of FIX)×weight (kg)×1.3.This increased his activity to 100%. One IU of rFIX increased FIX activity by 0.8%; the half-life of rFIX is 18-24 hours. The rFIX infusion was started intraoperatively and continued after surgery to maintain target FIX activity. He was discharged on POD 9 on rFIX bolus dosing of 5000 IU every 12 hours for an additional 5 days. Using continuous factor infusion, we managed to decrease the amount rFIX used by >60% while maintaining steady state FIX activity level.Neurocutaneous melanosis (NCM) is a rare disorder characterised by giant or multiple melanocytic nevi and meningeal melanosis or melanoma. Onset of neurological symptoms is typically in children younger than 2 years and can be rapidly fatal. We present the case of a 13-year-old adopted girl presenting with numerous congenital melanocytic nevi and a seizure. She had no significant previous neurological history. Electroencephalogram showed epileptiform discharges over the right frontal region. MRI of the brain showed T1 hyperintensity in the bilateral amygdala and anterior temporal lobes with corresponding hyperintensity on T2 and fluid attenuated inversion recovery. There was no hydrocephalus. Along with the history of nevi, these imaging findings were concerning for NCM. The patient is being managed with levetiracetam and trametinib and shows no further neurological decline at 1-year follow-up, providing prognostic hope in this case of NCM.In recent years, the success of long-term dental implants has remained problematic, especially because of the increasing rate of mineral balance changes in patients with partial loss of teeth, regardless of their age, race and sex. This article describes the experience of 6 years of treatment with dental implants in a patient with secondary loss of tooth and mineral imbalance (osteopenia) due to vitamin D deficiency, in collaboration with endocrinologist. Along with basic dental care, special medicine was prescribed for this pathology. The bone system was monitored through regular blood tests, skeletal bone densitometry and X-ray of the maxillofacial region. This management plan allowed dental implants to be maintained in good condition for 7 years.Endoscopic stapling is the preferred technique for treatment of symptomatic pharyngeal pouches. The use of stapling with a standard pharyngoscope can be successful in difficult access patients. This modification of the technique can prevent the conversion of an endoscopic approach to an open approach.Melanoma differentiation-associated gene 5 (MDA5) antibody, also known as anti-CADM140 antibody is recognised to be associated with rapidly progressive interstitial lung disease, which can be fatal within 3 months. It is also known to be associated with amyopathic dermatomyositis. We report a case of MDA5 antibody-associated interstitial pneumonia with autoimmune features, without cutaneous features of dermatomyositis, in a Sudanese patient with dual positive antibodies to Ro52. The patient notably had several features associated with poor prognosis, including age, high serum ferritin level, anti-Ro52 antibodies and progressive lung infiltrates during treatment.We report a case of 19-year-old man with gradual diminution of vision in both eyes since childhood. Polyinosinic acid-polycytidylic acid price His best-corrected visual acuity was 20/160, N16 in the right eye and 20/200, N16 in the left eye. Slit-lamp biomicroscopic examination revealed normal cornea, anterior segment, intraocular pressure and lens. Fundus of both eyes showed crowded optic disc with pigmentary changes. Ancillary tests were performed to aid in the diagnosis. A-scan ultrasound revealed short axial lengths with normal corneal diameter, anterior chamber depth and lens thickness. Optical coherence tomography of both eyes showed inner retinal layer folds. Electroretinogram of both eyes showed extinguished photopic as well as scoptopic responses. A diagnosis of posterior microphthalmos with pigmentary retinopathy was made. The patient was counselled regarding nature of the disease and the condition was managed with low vision aids.Surgeons are always in a dilemma for the management of paediatric facial fractures due to distinctive nature of growing facial skeleton. The ultimate treatment goal for paediatric fractures should be as conservative as possible with least invasive surgical approach that will access the fracture and least invasive surgical fixation that will allow stable reduction and will prevent any growth disturbances. We are presenting a case of 4- year old with panfacial fracture managed according to this principle using transmucosal titanium plates with acylic splint for sagittal split of palate.A very rare syndrome, 3q26.33-3q27. 2 microdeletion, has only been described in seven case reports previously, all of which highlight genotypic and phenotypic variations of the presentations identified in school-aged and adolescent children. The patients in these cases had varying sized deletions but overlapping manifestations. Hallmarks of the deletion include intrauterine growth restriction (IUGR), failure to thrive/feeding difficulty, dysmorphic facial features, delayed dentition, pes planus, intellectual/developmental delay, hypotonia and recurrent infections. This case report aims to document the presentation of 3q26.33-3q27.2 microdeletion in infancy for the first time in the literature. Through early recognition of specific genetic causes for IUGR, such as this microdeletion, we can better anticipate and prepare for the patient's needs in the neonatal period and in the future.

Less than two-thirds of children with abdominal pain in the emergency department receive analgesia. We sought to determine whether hyoscine butylbromide was superior to acetaminophen for children with nonspecific colicky abdominal pain.

We randomly allocated children aged 8-17 years with nonspecific colicky abdominal pain who presented to the pediatric emergency department of London Health Sciences Centre, London, Ontario to receive hyoscine butylbromide, 10 mg given orally, or acetaminophen, 15 mg/kg given orally (maximum 975 mg). We considered the minimal clinically important difference for the primary outcome (self-reported pain at 80 min) to be 13 mm on a 100 mm visual analogue scale. Secondary outcomes included administration of rescue analgesia, adverse effects and pain score less than 30 mm at 80 minutes.

A total of 236 participants (120 in the hyoscine butylbromide group and 116 in the acetaminophen group) were included in the trial. The mean visual analogue scale scores at 80 minutes were 29 mmr to acetaminophen in this setting. Both agents were associated with clinically important pain reduction, and either can be considered for children presenting to the emergency department with nonspecific colicky abdominal pain. Trial registration Clinicaltrials.gov, no. NCT02582307.Contextual drug-associated memories precipitate craving and relapse in cocaine users. Such associative memories can be weakened through interference with memory reconsolidation, a process by which memories are maintained following memory retrieval-induced destabilization. We hypothesized that cocaine-memory reconsolidation requires cannabinoid type 1 receptor (CB1R) signaling based on the fundamental role of the endocannabinoid system in synaptic plasticity and emotional memory processing. Using an instrumental model of cocaine relapse, we evaluated whether systemic CB1R antagonism (AM251; 3 mg/kg, i.p.) during memory reconsolidation altered (1) subsequent drug context-induced cocaine-seeking behavior as well as (2) cellular adaptations and (3) excitatory synaptic physiology in the basolateral amygdala (BLA) in male Sprague Dawley rats. Systemic CB1R antagonism, during, but not after, cocaine-memory reconsolidation reduced drug context-induced cocaine-seeking behavior 3 d, but not three weeks, later. CB1R antexposure to a drug-associated environment. Context-drug associative memories become destabilized on retrieval and must be reconsolidated into long-term memory stores to persist. Hence, targeted interference with memory reconsolidation can weaken maladaptive context-drug memories and reduce the propensity for drug relapse. Our findings indicate that cannabinoid type 1 receptor (CB1R) signaling is critical for context-cocaine memory reconsolidation and subsequent drug context-induced reinstatement of cocaine-seeking behavior. Furthermore, cocaine-memory reconsolidation is associated with CB1R-dependent immediate-early gene (IEG) expression and changes in excitatory synaptic proteins and physiology in the basolateral amygdala (BLA). Together, our findings provide initial support for CB1R as a potential therapeutic target for relapse prevention.Age-related memory deficits are correlated with neural hyperactivity in the CA3 region of the hippocampus. Abnormal CA3 hyperactivity in aged rats has been proposed to contribute to an imbalance between pattern separation and pattern completion, resulting in overly rigid representations. Recent evidence of functional heterogeneity along the CA3 transverse axis suggests that proximal CA3 supports pattern separation while distal CA3 supports pattern completion. It is not known whether age-related CA3 hyperactivity is uniformly represented along the CA3 transverse axis. We examined the firing rates of CA3 neurons from young and aged, male, Long-Evans rats along the CA3 transverse axis. Consistent with prior studies, young CA3 cells showed an increasing gradient in mean firing rate from proximal to distal CA3. However, aged CA3 cells showed an opposite, decreasing trend, in that CA3 cells in aged rats were hyperactive in proximal CA3, but possibly hypoactive in distal CA3, compared with young (Y) rats. We suggest that, in combination with altered inputs from the entorhinal cortex and dentate gyrus (DG), the proximal CA3 region of aged rats may switch from its normal function that reflects the pattern separation output of the DG and instead performs a computation that reflects an abnormal bias toward pattern completion.
