A Case of Multiple Sclerosis Presenting as Eight and Half Syndrome.
Multiple sclerosis (MS) is a chronic disease characterized by inflammation, demyelination, gliosis (scarring), and neuronal loss; the course can be relapsing-remitting or progressive. Manifestations of MS vary from a benign illness to a rapidly evolving and incapacitating disease requiring profound lifestyle adjustments. We report a 24 year old female who presented with right internuclear ophthalmoplegia with right lower motor neuron facial nerve palsy which is called eight and half syndrome. The etiology in our patient was multiple sclerosis which was confirmed by radio-imaging studies. Patient improved on pulse therapy of methyl prednisolone and tapering dose of steroids
Huge Sertoli-Leydig cell tumor: a rare case report
Sertoli-Leydig cell tumors (SLCTs), constitute less than 0.5% of all ovarian tumors. SLCT are rare after menopause (less than10%), 75 years, unmarried, postmenopausal since 30 years, presented with complaints of abdominal swelling. On examination, abdominal mass of 36 weeks, hard, immobile felt. Ultrasonography of abdomen showed lobulated solid cystic lesion of size 22 x 15 x 27 cms with bilateral ovaries not separately visualized. Moderate free fluid in the abdomen, suggestive of malignant neoplastic etiology. CECT Abdomen + pelvis suggestive of primary ovarian malignancy with omental deposits and pelvic adenopathy. CA 125- 415.1 Patient underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy with huge tumour mass excision (weight 5.25 kg) with umbilical hernia repair. Frozen section suggestive of a huge mass of 30 x 20 x 15 cm, multilobulated, yellowish white tan in colour, solid-cystic in consistency, seen arising from right ovary. Omentum appears normal. Histopathology report s/o- Moderately differentiated Sertoli Leydig cell tumor. Reporting the first, this huge, in this age group with atypical presentation
Functional and radiological outcomes of distal humerus fractures treated with pre-contoured locking compression plate
Background: Distal humerus intra-articular fractures are one of the complicated fractures managed by orthopaedic surgeons. We did a prospective and a retrospective study on 21 patients with these fractures treated with pre-contoured locking compression plate.Methods: The 21 patients in this series were followed for a minimum of 1 year. The prospective study cases were followed at 3 months, 6 months and annually. The rating system of the Mayo elbow functional scoring system was used. The radiological evaluation was done using standard AP and lateral views.Results: We had 14 patients with range of motion of 50-100 degrees. There was only one patient with range of motion of <50 degrees. 6 patients had the maximum range motion of >100 degrees. We had 6 (23.57%) excellent, 9 (42.85%) good, 5 (23.80%) fair and 1 (4.7%) poor in the Mayo elbow scoring at the end of 1 year. We were able to compare our outcomes with a study done by Kumar et al done in 2017. They had 27 (89.66%) of excellent and good results as opposed to 27 (79.4%) in our study. Out of 21 patients in our study 17(80.95%) patients had good 11 (52.5%) / excellent 6 (28.5%) results. This was comparable with Jupiter et al. His study of 34 patients 26 (79.40/0) patients showed good 14 (41%) / excellent 13 (38.4%) result.Conclusions: Pre-contoured locking compression plate appears to be technically an ideal implant for comminuted osteoporotic bone providing an angle stable construct
Cruciate retaining versus posterior-stabilized total knee arthroplasty: a short-term comparative study
Background: Total knee arthroplasty has got excellent results. Among the techniques (posterior-stabilized vs posterior cruciate retaining total knee arthroplasty) it is unclear whether one design has superior outcome over another. The purpose of the present study was to directly compare clinical and radiological outcomes of these two designs.Methods: A prospective study involving 36 patients who received a cruciate-retaining implant were compared to 30 patients who received posterior-stabilized prosthesis. At 3 months follow-up time clinical and radiological evaluation done and results were analyzed.Results: At 3 months follow-up time mean knee society scores improved from 49.9/46.9 (objective/subjective score) points to 80.9/82.5 points in the cruciate-retaining group and from 48.2/43 (objective/subjective score) points to 80.4/80.2 points in the posterior-stabilized group. The ranges of motion was 117.2° (range, 90° to 130°) and 125.3° (range, 100° to 140°) in the cruciate-retaining and posterior-stabilized group respectively, at 3 month follow-up. One patient had post-operatively periprosthetic fracture reported after 2 weeks (treated conservatively), one had superficial infection (treated with dressing) and one patient with superfical infection required debridement.Conclusions: This study did not conclusively demonstrate the superiority of one knee design over the other, suggesting that the choice of implant should be based on surgeon preference, patients knee dimensions, pre-op knee deformity and existing pathology of the posterior cruciate ligament
We never go out of Style: Motion Disentanglement by Subspace Decomposition of Latent Space
Real-world objects perform complex motions that involve multiple independent
motion components. For example, while talking, a person continuously changes
their expressions, head, and body pose. In this work, we propose a novel method
to decompose motion in videos by using a pretrained image GAN model. We
discover disentangled motion subspaces in the latent space of widely used
style-based GAN models that are semantically meaningful and control a single
explainable motion component. The proposed method uses only a few
ground truth video sequences to obtain such subspaces. We extensively evaluate
the disentanglement properties of motion subspaces on face and car datasets,
quantitatively and qualitatively. Further, we present results for multiple
downstream tasks such as motion editing, and selective motion transfer, e.g.
transferring only facial expressions without training for it.Comment: AI for content creation, CVPRW-202
A security suite for wireless body area networks
Wireless Body Area Networks (WBANs) have gained a lot of research attention
in recent years since they offer tremendous benefits for remote health
monitoring and continuous, real-time patient care. However, as with any
wireless communication, data security in WBANs is a challenging design issue.
Since such networks consist of small sensors placed on the human body, they
impose resource and computational restrictions, thereby making the use of
sophisticated and advanced encryption algorithms infeasible. This calls for the
design of algorithms with a robust key generation / management scheme, which
are reasonably resource optimal. This paper presents a security suite for
WBANs, comprised of IAMKeys, an independent and adaptive key management scheme
for improving the security of WBANs, and KEMESIS, a key management scheme for
security in inter-sensor communication. The novelty of these schemes lies in
the use of a randomly generated key for encrypting each data frame that is
generated independently at both the sender and the receiver, eliminating the
need for any key exchange. The simplicity of the encryption scheme, combined
with the adaptability in key management makes the schemes simple, yet secure.
The proposed algorithms are validated by performance analysis.Comment: 20 pages, 10 figures, 3 tables, International Journal of Network

Isolated Amoebic Abscess of Spleen
Amoebic liver abscess is the most common extraintestinal manifestation of amoebiasis. Extrahepatic amoebic abscesses have occasionally been described in the lung, brain, and skin and presumably result from hematogenous spread. Isolated amoebic abscess of spleen has been reported scarcely in literature. We report here a case of isolated amoebic abscess of spleen
Hirayama Disease - A Variant of Motor Neuron Disease and Role of Flexion MRI in Diagnosis
Hirayama disease is a monomyelic variant of motor neuron disease (MND) and has distinctive features of male predominance, asymmetric involvement of upper extremities with a self limiting course. Flexion MRI (magnetic resonance imaging) forms the main stay for diagnosis of this condition. Here we report such an unusual case of Hirayama disease in a male patient of 20 years who presented with weakness and atrophy in right upper limb. Careful clinical examination will help to use the flexion MRI studies for the diagnosis of this condition as done in our case
Intent Identification and Entity Extraction for Healthcare Queries in Indic Languages
Scarcity of data and technological limitations for resource-poor languages in
developing countries like India poses a threat to the development of
sophisticated NLU systems for healthcare. To assess the current status of
various state-of-the-art language models in healthcare, this paper studies the
problem by initially proposing two different Healthcare datasets, Indian
Healthcare Query Intent-WebMD and 1mg (IHQID-WebMD and IHQID-1mg) and one real
world Indian hospital query data in English and multiple Indic languages
(Hindi, Bengali, Tamil, Telugu, Marathi and Gujarati) which are annotated with
the query intents as well as entities. Our aim is to detect query intents and
extract corresponding entities. We perform extensive experiments on a set of
models in various realistic settings and explore two scenarios based on the
access to English data only (less costly) and access to target language data
(more expensive). We analyze context specific practical relevancy through
empirical analysis. The results, expressed in terms of overall F1 score show
that our approach is practically useful to identify intents and entities
