Abstract
OBJECTIVE To compare physiological and biochemical responses in stable preterm neonates and their parents following kangaroo mother care (KMC) and kangaroo father care (KFC). STUDY DESIGN We conducted a prospective cross-over design study of stable preterm neonates of <35 weeks gestation in a tertiary Neonatal Unit in Toronto. All neonates received KMC and KFC for 1 h on consecutive days in a random order. Heart rate, temperature, blood pressure, oxygen saturation and salivary cortisol in infants before and after kangaroo care and heart rate, temperature and salivary cortisol in parents before and after kangaroo care were measured. Pairwise comparisons of changes in these measures were analyzed. RESULT Twenty-six sets of neonates and their parents were studied for physiological parameters, of which 19 had adequate samples for salivary cortisol assessment. The infants had a mean birth weight of 1096 g (s.d.=217) and a mean postmenstrual age at study of 32 weeks (s.d.=2). There were no significant differences in the changes in mean heart rate (P=0.51), temperature (P=0.37), oxygen saturation (P=0.50), systolic blood pressure (P=0.32), mean blood pressure (0.10) and salivary cortisol (P=0.50) before and after KMC or KFC in the neonates. The changes in mean heart rate (P=0.62), temperature (P=0.28) and salivary cortisol (P=0.59) before and after kangaroo care were similar between mothers and fathers. CONCLUSION No significant differences in physiological and stress responses were identified following KMC or KFC in preterm neonates. KFC may be as safe and as effective as KMC.

Abstract
Patient presented as a case of appendicular perofration with pyoperitoneum leading to localized peritonitis which is a common surgical emergency. Primary omental torsion is a rare diagnosis and very difficult to diagnose at the emergency room. We report a patient with omental torsion and further gangrene of the omentum leading to pyoperitoneum mimicking appendicuar perforation peritonitis. A review of literature is also included.
Introduction Primary omental torsion is a rare cause of acute abdomen in adults and presents with variable signs and symptoms. Establishing a preoperative diagnosis may be difficult in the emergency setting. It is rarely diagnosed preoperatively as it mimics common surgical emergencies such as acute appendicitis, appendicular perforation, acute cholecystitis and perforated peptic ulcers and can lead to the clinical deterioration of patient if missed Presentation of case A 47 years old male was taken to the operating room with a diagnosis of appendicular perforation peritonitis and during surgery was found to have a primary omental gangrene with pyoperitoneum, for which omentectomy and peritoneal lavage was performed. Discussion Torsion of the omentum is a condition in which the organ twists on its long axis to such an extent that its vascularity is compromised. Omental torsion can be primary (idiopathic) or secondary, depending on an underlying cause. Primary omental torsion was first described by Eitel in 1899. However, very few cases have been reported. Our case was a rare case presenting with omental gangrene with pyoperitoneum mimicking appendicular perforation peritonitis. Conclusion Primary omental torsion is a rare diagnosis. A high index of clinical suspicion is required for a preoperative diagnosis. In doubtful cases a CT scan may be helpful. Surgical excision of the omentum remains the treatment of choice; however, conservative management may be attempted in an uncomplicated omental torsion.

Abstract
Histone deacetylase inhibitors (HDACis) have emerged as novel therapeutic agents for cancer. Currently, four HDACis are approved by the Food and Drug Administration (FDA) to treat various hematologic malignancies. Panobinostat (LBH-589, trade name Farydak®, developed and marketed by Novartis) is a potent pan-HDACi with demonstrated anticancer activities against multiple myeloma, a B-cell malignancy, at a low nanomolar range in preclinical settings, and in 2015 was granted FDA approval for the treatment of relapsed and refractory multiple myeloma. Here, we review the development of HDACis, the unique features of panobinostat, and the rationale for developing panobinostat in a combination setting for the treatment of multiple myeloma. We also review the completed and ongoing clinical trials testing the efficacy of panobinostat in combination therapies and highlight future therapeutically relevant strategies.

Abstract
OBJECTIVE To determine oxygen saturation profile over 6 h monitoring period in healthy late-preterm and term neonates during the first 48 h of age, and to assess the impact of gestational age, birth weight and method of delivery on this profile. STUDY DESIGN Prospective cohort study of measurement of SpO2 over 6 h in 20 late-preterm (35 to 36 weeks gestation) and 40 term infants within 12 to 48 h of birth was conducted. Infants with cardiorespiratory symptoms or need for cardiorespiratory support at birth were excluded. Percentage time spent at SpO2 >90% and ⩽90% was calculated by gestational age and birth weight. RESULT Late-preterm infants and infants born weighing <2.5 kg spent approximately 7% of the time at SpO2 ⩽90%; this time decreased as gestational age and birth weight increased. Time at SpO2 >90% was significantly different between late-preterm and term infants (93% (5%) vs 96% (3%); P =0.002). Time at SpO2 >90% was not significantly different between males and females (95% (5%) vs 95% (4%), both n=30; P =0.72) or between vaginal births and cesarean births (95% (4%), n=32, vs 95% (4%), n=28; P =0.39). Cumulative time with SpO2 <90 was mean (s.d.) of 25 (18) in preterm vs 13 (10) min in term infants. CONCLUSION Over a 6-h period healthy late-preterm and term infants spent significant time at SpO2 ⩽90%. Lower gestation and lower birth weight were associated with higher time at SpO2 ⩽90%.

Abstract
Treatment in medical oncology is gradually shifting from the use of nonspecific chemotherapeutic agents toward an era of novel targeted therapy in which drugs and their combinations target specific aspects of the biology of tumor cells. Multiple myeloma (MM) has become one of the best examples in this regard, reflected in the identification of new pathogenic mechanisms, together with the development of novel drugs that are being explored from the preclinical setting to the early phases of clinical development. We review the biological rationale for the use of the most important new agents for treating MM and summarize their clinical activity in an increasingly busy field. First, we discuss data from already approved and active agents (including second- and third-generation proteasome inhibitors (PIs), immunomodulatory agents and alkylators). Next, we focus on agents with novel mechanisms of action, such as monoclonal antibodies (MoAbs), cell cycle-specific drugs, deacetylase inhibitors, agents acting on the unfolded protein response, signaling transduction pathway inhibitors and kinase inhibitors. Among this plethora of new agents or mechanisms, some are specially promising: anti-CD38 MoAb, such as daratumumab, are the first antibodies with clinical activity as single agents in MM. Moreover, the kinesin spindle protein inhibitor Arry-520 is effective in monotherapy as well as in combination with dexamethasone in heavily pretreated patients. Immunotherapy against MM is also being explored, and probably the most attractive example of this approach is the combination of the anti-CS1 MoAb elotuzumab with lenalidomide and dexamethasone, which has produced exciting results in the relapsed/refractory setting.

Abstract
The natural tendency of carbon nanotubes (CNTs) to agglomerate is an underlying reason that prevents the realization of their full potential. On the other hand, covalent functionalization of CNTs to control dispersion leads to disruption of π-conjugation in CNTs and the non-covalent functionalization leads to a weak CNT-polymer interface. To overcome these challenges, we describe the characteristics of fostering of direct nucleation of polymers on nanostructured carbon (CNTs of diameters (~2-200 nm), carbon nanofibers (~200-300 nm), and graphene), which culminates in interfacial adhesion, resulting from electrostatic and van der Waals interaction in the hybrid nanostructured carbon-polymer architecture. Furthermore, the structure is tunable through a change in undercooling. High density polyethylene and polypropylene were selected as two model polymers and two sets of experiments were carried out. The first set of experiments was carried out using CNTs of diameter ~2-5 nm to explore the effect of undercooling and polymer concentration. The second set of experiments was focused on studying the effect of dimensionality on geometrical confinements. The periodic crystallization of polyethylene on small diameter CNTs is demonstrated to be a consequence of the geometrical confinement effect, rather than epitaxy, such that petal-like disks nucleate on large diameter CNTs, carbon nanofibers, and graphene. The application of the process is illustrated in terms of fabricating a system for cellular uptake and bioimaging.

Abstract
OBJECTIVE We present an interesting case of superior and posterior semicircular canal dehiscence in pregnancy. METHOD We present a case report and a review of the world literature concerning semicircular canal dehiscence. CASE REPORT A 34-year-old woman presented with sound and pressure induced vertigo at 22 weeks gestation. A thinly sliced computed tomography (CT) scan of the petrous temporal bones viewed with coronal reconstructions was performed post-partum. This showed the presence of both left superior canal and posterior canal dehiscence. CONCLUSION To our knowledge this is the first reported case of semicircular canal dehiscence in pregnancy. The diagnosis of semicircular canal dehiscence should be suspected in pregnant patients with sound induced vertigo.
