Postvaginal Delivery Caecal Volvulus and Perforation

Intestinal obstruction is an uncommon complication of pregnancy and pueperium. It has different etiologies and voluvlus is one of the common causes. High index of suspicion is needed to diagnose it as initial presentation is nonspecific and that is critical to avoid adverse outcomes. We presented here one of these cases that followed vaginal delivery and ended with caecal perforation and hemicolectomy

3 Tesla MRI surface coil: Is it sensitive for prostatic imaging??

Objective: This study aimed to check the sensitivity of phased array surface coli of 3T MRI, in pre-sampling diagnosis of prostate cancer, in an attempt to use it instead of endorectal coil.Patients and methods: This was a prospective comparative study, included 20 male patients, presented with suspected prostate cancer due to unexplained high PSA. The study protocol was approved by the ethics committee in Al-Mana General Hospital.Results: Prostate cancer was correctly diagnosed by T2w sequence within 9 patients, 10 by DW&T2w, 13 by T2w – DW-DCE and 14 by of T2w-DW-DCE-MRS sequences.Conclusion: 3T MRI imaging using phased array surface coil is a useful diagnostic tool for detecting prostate cancer, trustworthy when compared to endorectal approach

A Theoretical Comparison of the Economic Impact of Large and Small Events

In response to the increasing debate on the relative worth of small events compared to large events, we create a theoretical model to determine whether smaller events are more likely to create positive economic impact. First, event size and city size are redefined as continuums of resources. The concepts of event resource demand (ERD) and city resource supply (CRS) are introduced, allowing for a joint analysis of supply and demand. When local economic conditions are brought into the analysis, the framework determines how a city resource deficiency or surplus affects the economic impact of an event. This resource-based approach assists public officials and event organizers in making more rational decisions for hosting events when they pursue positive economic impacts. Specifically, we find small events have a higher potential for positive economic impact and hosting multiple smaller-sized events is a better strategy than hosting a big event

Komunikasi Pemerintah Kota Medan Dalam Menanggulangi Penyakit Masyarakat

Penelitian ini merupakan penelitian lapangan meneliti masalah kebijakan pemerintah melalui komunikasi Pemerintah Kota Medan dalam memberantas penyakit masyarakat dalam hal ini prostitusi. Metode penelitian yang digunakan dalam penelitian ini adalah metode kualitatif deskriptif dengan pendekatan fenomenologi, dan menggunakan teori komunikasi. Penelitian ini bertujuan menganalisa masalah penyakit masyarakat prostitusi di Kota Medan, dan bagaimana cara penanggulangannya. Hasil penelitian menunjukkan bahwa penyakit masyarakat prostitusi sulit di berantas kerna beberapa factor yaitu faktor ekonomi, faktor pendidikan/skill (tidak punya keahlian), faktor agama (kurangnya pendidikan agama). &nbsp

Analysing Success Factors in the Development of Absorptive Capacity in Pharmaceutical Organisations based in Pakistan

Absorptive capacity is a developing research topic within the knowledge management field, whereby different models and methods of capturing new knowledge is being explored. Business Processes and human-centered systems at macro level, in relation to absorptive capacity, have been explored by researchers, but typically in a generalised form. Antecedents highlighting the successful implementation of absorptive capacity processes have not been studied extensively so far. Therefore, this study, through critical exploration of existing success factors within pharmaceutical organisations based in Pakistan, attempts to highlight the requirements for the effective development of absorptive capacity in the workplace. The results show that factors relating to employees and management, both mid-level and senior, are critical in the successful development of absorptive capacity. Furthermore, this study explores new pathways for critical evaluation of absorptive capacity in relation to employees and management within pharmaceutical organisations

Should Organisations Compete or Collaborate when Absorbing New External Knowledge?

Organisations possessing significant resources (Resource Based View) or knowledge, as their significant capability (Dynamic Capability View), are often unaware of their own ability to acquire new knowledge entering the enterprise (level of absorptive capacity); this unawareness can lead to reduced marketplace performance and incorrect decision making, which may result in the wastage of organisational resources, including employee knowledge. This study highlights the key differences in absorptive capacity which firms possess, in the context of resource based and dynamic capability views. Based on these differing perspectives, options are provided for companies who wish to compete or mate/merge with competitors in the market, while discussion is given on the considerations that organisations must take before adopting a suggested option

Cryoprotectant-free vitrification of human spermatozoa in new artificial seminal fluid

Vitrification is a new method that has been recently introduced in Assisted Reproduction Technique programs. The aim of this study was to design a new medium similar to normal human seminal fluid (SF), formulation artificial seminal fluid (ASF), and to compare the cryoprotective potency of this medium with SF and human tubal fluid (HTF) medium. Thirty normal ejaculates were processed with the swim-up technique and sperm suspensions were divided into four aliquots: (i) fresh sample (control); (ii) vitrification in HTF medium supplemented with 5 mg/mL human serum albumin and 0.25 mol sucrose (Vit HTF); (iii) vitrification with patients' SF (Vit SF); and (iv) vitrification in ASF (Vit ASF). After warming, sperm parameters of motility, viability, and morphology were analyzed using WHO criteria. Also, sperm pellets were fixed in 2.5% glutaraldehyde and processed for scanning electron microscopy and transmission electron microscopy observations. The results showed that progressive motility (46.09 ± 10.33 vs. 36.80 ± 13.75), grade A motility (36.59 ± 11.40 vs. 16.41 ± 11.24), and normal morphology (18.74 ± 8.35 vs. 11.85 ± 5.84) and viability (68.22 ± 10.83 vs. 60.86 ± 11.72) of spermatozoa were significantly higher in Vit ASF than in Vit HTF. All parameters were better in Vit ASF than in Vit SF, but only viability was significantly different (p = 0.006). After cryopreservation, deep invagination in cytoplasm and mechanically weak point sites and folded tail were commonly observed. But, this phenomenon was more significant in Vit HTF and Vit SF than in ASF (p < 0.05). In transmission electron microscopy evaluation, acrosome damage, plasma membrane loss, chromatin vacuolation, and disruption of mitochondria arrangement and structures were observed in all vitrified groups. Adherence of several tail sections together was also seen in all cryo groups. But this was seen more in Vit HTF and Vit SF than in ASF (p < 0.05). In conclusion, vitrification of human spermatozoa with ASF can effectively preserve the quality of sperm motility in comparison with Vit HTF. © 2016 American Society of Andrology and European Academy of Andrology
