30 yrs. old unmarried gentleman works as chef with no signifi cant past medical history presented with 4 days history of oral ulcers and rash that was started from face than spread to arms and later to involve trunk and legs.fever only develops on the day of presentation. No h/o recent sexual contact,travel history. No red fi ags no h/o weight loss. No family history of malignancy On examination he was febrile,tachycardiac with stable vitals. On examination he was having extensive cutaneous lesions it was tender with infi amed papeulse, plaques and nodules.also noted extensive oral ulcers over hard palate, tongue. Biopsy of the skin lesions shows netriphilic dermatosis (Sweet Syndrome) Patient was worked up to rule out hematological malignancy /solid organ malignancy Periperal blood smear does not shows any malignant cells Pan CT scan also negative for malignancy Autoimmune workup also negative. Patient was started on oral prednisolone and patient responded to treatment very well.

Objective: To report a very rare case of malignant pheochromocytoma presented with atypical symptoms of polyuria, polydipsia, weight loss and hypertension Case Report: 31 year old female patient know to have hypertension for the last 1 year under active follow up with general practitioner currently presented with 12 kg weight loss for the past 1 year, polyuria, polydipsia, diaphoresis, palpitations and with hypertensive urgency also diagnosed to have newly diagnosed diabetes mellitus. Investigations: she underwent usg abdomen that shows left adrenal mass that was confirmed by CT A/P and MRI abdomen that shows left adrenal mass and raised urine catecholamines, metanephrines; also diagnosed newly diagnosed diabetes mellitus. Progress: An open left adrenalectomy was done with clearance of enlarged lymph nodes and histological findings confirmed pheochromocytoma with metastasis to adjacent lymph nodes. Repeat urine catecholamines was markedly reduced and b.p improved and patient was off from diabetic medications. Conclusions: A total of 8 cases of malignant pheochromocytoma were reported in singapore itself during the period of 1993-2007.Although malignant pheochromocytoma is rare, pheochromocytoma can present as young hypertension and need to be investigated.

Scalable synthesis of MOFs-derived ZnO/C nanohybrid: efficient electrocatalyst for oxygen evolution reaction in alkaline medium

One of the main goals of energy conversion research is to develop effi cient, nonprecious, and stable electrocatalysts to replace defi cient and unstable noble metal catalysts. Hence, this work described metal–organic frameworks (MOFs) derived ZnO/C hybrid via a hydrothermal route grown on the surface of conducting stainless steel substrate (SS). By using multiple physical techniques (XRD, FTIR, TEM, XPS, and EDX), we compared structural and morphological properties of ZnO/C hybrid and MOF-5 electrodes. The electrocatalytic behaviour of amiable and economical ZnO/C/SS catalyst was noticed in catalyzing oxygen evolution reaction (OER) in one mole KOH electrolyzer with low overpotential and excellent stability. Cyclic sweep voltammetry indicated that the ZnO/C/SS hybrid only needs an ultralow overpotential of 282 mV to achieve a current density of 10 mA  cm −1 for OER. In addition, ZnO/C/SS with a low Tafel slope of 39.3 mV/dec and higher 0.29  s −1 turnover frequency can serve as a profi cient electrocatalyst compared to commercial ZnO and MOF-5 electrodes. The stability of ZnO/C/SS hybrid electrocatalyst approaching minor chronoamperometric degradation after 55 h. The electrochemical response depicts that the successful synthesis of MOF-derived ZnO/C/SS catalyst provided abundant active centers and boosted an electron- rich environment to promote its future prosperity and facilitate practical applications for electrochemical water-splitting.

Background: The aim of this study was to compare the results of the standard once-weekly Ponseti casting technique to an accelerated twice-weekly regimen in our population cohort. Methods: A prospective randomized controlled study was conducted with a total of 100 consecutive patients (158 feet) being enrolled for the study. Fifty patients were randomized to each group and followed up for at least one year. Results: Initial mean Pirani score was 4.67 ± 0.73 in the standard group and 4.35 ± 0.76 in the accelerated group, and the score decreased to 0.34 ± 0.38 and 0.35 ± 0.31, respectively. Initial mean Dimeglio score was 11.75 ± 2.75 in the standard group and 10.51 ± 2.57 in the accelerated group, and the score decreased to 0.79 ± 0.77 and 0.79 ± 0.71, respectively, immediately after casting. The average number of casts required to correct all the deformities was 6.3 ± 1.2 in the standard group and 6.1 ± 1.4 in the accelerated group (p = 0.45). Average time spent in cast was 58.2 ± 8.3 days in the standard group and 39.5 ± 5.2 days in the accelerated group (p < 0.001). Percutaneous Achilles tendon tenotomy was done in 86.42% in the standard group and in 84.41% in the accelerated group (p = 0.72). Final results were assessed by using a modified functional rating scoring system: 55.55% clubfeet had excellent results and 44.45% had good results in the standard group, whereas 66.23% clubfeet had excellent results and 33.77% had good results in the accelerated group. None amongst the two groups had fair or poor results. Conclusions: These results suggest that the accelerated Ponseti technique significantly reduces the correction time without affecting the final results and that it is as safe and effective as the traditional Ponseti technique.

RPL routing protocol for low-power and lossy networks is an Internet Engineering Task Force (IETF) recommended IPv6 based protocol for routing over Low power Lossy Networks (LLNs). RPL is proposed for networks with characteristics like small packet size, low bandwidth, low data rate, lossy wireless links and low power. RPL is a proactive routing protocol that creates a Directed Acyclic Graph (DAG) of the network topology. RPL is increasingly used for Internet of Things (IoT) which comprises of heterogeneous networks and applications. RPL proposes a single path routing strategy. The forwarding technique of RPL does not support multiple paths between source and destination. Multipath routing is an important strategy used in both sensor and ad-hoc network for performance enhancement. Multipath routing is also used to achieve multi-fold objectives including higher reliability, increase in throughput, fault tolerance, congestion mitigation and hole avoidance. In this paper, M-RPL (Multi-path extension of RPL) is proposed, which aims to provide temporary multiple paths during congestion over a single routing path. Congestion is primarily detected using buffer size and packet delivery ratio at forwarding nodes. Congestion is mitigated by creating partially disjoint multiple paths and by avoiding forwarding of packets through the congested node. Detailed simulation analysis of M-RPL against RPL in both grid and random topologies shows that M-RPL successfully mitigates congestion and it enhances overall network throughput.

Cloud storage as a service provides high scalability and availability as per need of user, without large investment on infrastructure. However, data security risks, such as confidentiality, privacy, and integrity of the outsourced data are associated with the cloud-computing model. Over the year`s techniques such as, remote data checking (RDC), data integrity protection (DIP), provable data possession (PDP), proof of storage (POS), and proof of retrievability (POR) have been devised to frequently and securely check the integrity of outsourced data. In this paper, we improve the efficiency of PDP scheme, in terms of computation, storage, and communication cost for large data archives. By utilizing the capabilities of JAR and ZIP technology, the cost of searching the metadata in proof generation process is reduced from O(n) to O(1). Moreover, due to direct access to metadata, disk I/O cost is reduced and resulting in 50 to 60 time faster proof generation for large datasets. Furthermore, our proposed scheme achieved 50% reduction in storage size of data and respective metadata that result in providing storage and communication efficiency.
