Varsha Dalal, Manveen Kaur, Reetika Menia, Fouzia Siraj, Amar Bhatnagar, Usha Agrawal
Mesenteric masses are infrequent lesions ranging from benign cysts to aggressive malignancies and often present a diagnostic and therapeutic challenge. The mesentery is a frequent recipient of metastases from the gastrointestinal tract, pancreas, and biliary cancers. Primary mesenteric tumors are relatively rare, mostly mesenchymal in origin and benign in nature. Examples include gastrointestinal stromal tumors and smooth muscle tumors. We describe a 50-year-old woman, who presented with a lump in the left hypochondrium along with altered bowel habits of 2 years' duration...

Mammary sclerosing lobular hyperplasia is an uncommon benign fibroproliferative lesion of adolescent and young women, often of African American heritage with an incidence of ~3%. Patients generally complain of a palpable, painless, or slightly tender and well-defined lump in breast. Very rarely, this lesion may be bilateral and diffuse. The definitive diagnosis of sclerosing lobular hyperplasia requires histopathologic evaluation. Here, we describe a case of diffuse sclerosing lobular hyperplasia in a 29-year-old African American woman that required bilateral mastectomy and recurred bilaterally requiring second resections...

REVIEW
Saskia Haegens, Elana Zion Golumbic
Here we review the role of brain oscillations in sensory processing. We examine the idea that neural entrainment of intrinsic oscillations underlies the processing of rhythmic stimuli in the context of simple isochronous rhythms as well as in music and speech. This has been a topic of growing interest over recent years; however, many issues remain highly controversial: how do fluctuations of intrinsic neural oscillations-both spontaneous and entrained to external stimuli-affect perception, and does this occur automatically or can it be actively controlled by top-down factors? Some of the controversy in the literature stems from confounding use of terminology...

In the study of lime as the basic component of historical mortars and plasters, four lime putties prepared from various kinds of lime of various granulometry and by various ways of preparation were evaluated. The rheological properties and micro-morphologic changes, growing of calcite crystals, and rate of carbonation were monitored. The lime putty prepared from lump lime achieves the best rheological properties, yield stress 214.7 Pa and plastic viscosity 2.6 Pa·s. The suitability of this lime putty was checked by testing the development of calcium hydroxide and calcite crystals using scanning electron microscopy and environmental scanning electron microscopy...

Optical spectra of signals at the output of semiconductor optical amplifiers (SOA) provide useful insight into amplifier nonlinearities. In this work, we determine the parameters of an analytical SOA model with a pump-probe experiment by evaluating the measured spectra of the pump and probe pulses at the SOA output. The analytical lumped SOA model considers carrier depletion, carrier recovery, spectral hole burning, two-photon absorption, and we include an additional effect termed 'two-photon induced free-carrier absorption', that is responsible for creating an identifiable blue-shifted component in the spectra...

We present a neuromorphic current mode implementation of a spiking neural classifier with lumped square law dendritic nonlinearity. It has been shown previously in software simulations that such a system with binary synapses can be trained with structural plasticity algorithms to achieve comparable classification accuracy with fewer synaptic resources than conventional algorithms. We show that even in real analog systems with manufacturing imperfections (CV of 23.5% and 14.4% for dendritic branch gains and leaks respectively), this network is able to produce comparable results with fewer synaptic resources...

Radhakrishna Ramchandani, Sunil Chumber
Thyroglossal duct cysts are one of the commonest benign midline neck swellings. These are the remnants of the embryologic duct that fails to regress by the 10th week of fetal development. Generally, these are sporadic, slowly enlarging midline neck lumps, with half of them presenting before the age of 30. However, despite their relative frequency, reports of familial inheritance are rare. A review of literature reveals a total of 25 patients from 8 families showing a familial inheritance pattern worldwide. We describe here a 9th family with 5 affected patients taking the total number of cases to 30...

The relatively low incidence and often atypical clinical presentation of soft-tissue sarcomas (STS) impedes early and adequate diagnosis. Patients may report on recently enlarged soft-tissue swellings, infrequently complain of painful lesions, or even have no symptoms at all.A thorough diagnostic work-up is essential in order to distinguish between benign soft-tissue tumours and STSs. Patient history, clinical features and radiological findings all help in assessing the underlying pathology. 'Worrying' features such as recent increase in size, deep location relative to the fascia, a tumour exceeding 4 cm in size, and invasive growth patterns seen on imaging should prompt verification by biopsy...

Piyush Joshi, Rohit Sharma
Introduction: Screening mammography is used for detection of breast cancer and is interpreted using the Breast Image Reporting and Data System (BIRADS) convention. It is not routinely offered to women in countries which do not have a national screening programme resulting in a challenge for the radiologist who has to interpret these in the absence of previous mammograms. Aim: To analyse benign and probably benign lesions in screening mammograms in a hitherto unscreened population and suggest protocols to increase diagnostic confidence...

INTRODUCTION: Metaplastic carcinoma of the breast includes a heterogeneous group of neoplasms characterized by admixture of adenocarcinoma with area of squamous, chondroid and osseous differentiation. If the tumor shows pure squamous differentiation, it is designated as squamous carcinoma. SCCB accounts for less than 1% of all invasive breast carcinoma. It can present as cystic lesions and simulate a breast abscess. CASE REPORT: A 75-year old woman was visited at our General Surgery Unit for a palpable lump, about 5 cm in size, at the lower inner quadrant of right breast...

Intradiploic epidermoid cyst is an uncommonly occurring neoplasm, and only about 200 cases are reported in the form of isolated case report. It is presumed to occur due to ectodermal cells in inclusion in the bone tissue during embryonic life neural tube closure. It commonly remains asymptomatic or rarely presents as a bony lump in the skull bone. Authors report present an interesting case, which presented with swelling, and underwent successful surgical resection. Pertinent literature along with diagnosis and management is briefly reviewed...

BACKGROUND: Adolescent idiopathic scoliosis, in which obvious curves are visible in radiographic images, is also seen in combination with lumps in the back. These lumps contribute to inclination, which can be measured by a scoliometer. To the authors' knowledge, there are no previous formulas combining thoracic and lumbar scoliometer values simultaneously to predict thoracic and lumbar Cobb angles, respectively. This study aimed to create more accurate two-parameter mathematical formulas for predicting thoracic and lumbar Cobb angles...

In the context of the trans crestal maxillary sinus lift, a wide variety of biomaterials have been used to fill the sub-antral space over the years. The materials that have a pasty consistency and are smooth and free from lumps are the most suitable to come into contact with the Schneiderian membrane which, if torn, cannot perform its graft containment function. In this study, a micronized heterologous bone in a collagen matrix of two different percentages was used in order to fill the maxillary sinus. Before using biomaterial as filler, a spray form of hyaluronic acid was used to disinfect the surgical site before and after the surgery, along with more consistent and pasty form of gel of hyaluronic acid being used in order to facilitate the detachment of the membrane...

INTRODUCTION: An interparietal inguinal hernia is a rare form of hernia. In this type of hernia, the sac passes between the layers of the abdominal wall of the inguinal canal area. Although its treatment is very simple but pre-operative diagnosis is really a challenging issue. PRESENTATION OF CASE: A 62 years old male patient presented with complaint of a large swelling over right lower abdomen with absence of right testes since birth. The lump was measured 26×22cm in size...

Neurofibromatosis 1 (NF1) patients are generally at higher risk of developing common malignant tumors such as brain and soft tissue tumors. These patients are 5-fold increased the risk of developing breast cancer by the age of 50 years after that the risk remains the same. The most common reported cancer is infiltrating duct carcinoma. We report a case of 61-year-old female with NF1 presented with pain and breast lump for the past 2 months. On mammography, a retroareolar solid cystic lesion measuring 32 mm × 30 mm × 30 mm was noted which was definitive for malignancy...

C Hare, T Bonakdar, M Ghadiri, J Strong
Tablets are the most common solid dosage form of pharmaceutical active ingredients due to their ease of use. Their dissolution behaviour depends on the particle size distribution and physicochemical properties of the formulation, and the compression process, which need to be optimised for producing consistently robust tablets, as weaker tablets are often prone to breakage during production, transport and end use. Tablet strength is typically determined by diametric compression and friability tests. The former gives rise to propagation of a crack on a plane along the compression axis, whilst the latter, carried out in a rotating drum, incurs surface damage and produces chips and debris...

OBJECTIVE: Identify methods to support the node-making process in network meta-analyses (NMAs) of non-pharmacological treatments. DESIGN: We proceeded in two stages. First, we conducted a literature review of guidelines and methodological articles about NMAs to identify methods proposed to lump interventions into nodes. Second, we conducted a systematic review of NMAs of non-pharmacological treatments to extract methods used by authors to support their node-making process...

This paper investigates the possibility of reproducing the self-sustained oscillation of the tongue tip in alveolar trills. The interest is to study the articulatory and phonatory configurations that are required to produce alveolar trills. Using a realistic geometry of the vocal tract, derived from cineMRI data of a real speaker, the paper studies the mechanical behavior of a lumped two-mass model of the tongue tip. Then, the paper proposes a solution to simulate the incomplete occlusion of the vocal tract during linguopalatal contacts by adding a lateral acoustic waveguide...
