Background and Objective: Emphysematous pyelonephritis (EPN) is a rare, life-threatening necrotizing renal parenchymal infection. Traditional management of EPN with nephrectomy had a mortality of 40-50%. The purpose of this case series was to assess the management, biochemical factors, and outcome of EPN patients. Methods: In this retrospective study, patients admitted to The Indus Hospital, Karachi with a diagnosis of EPN from January 2010 to February 2019, were grouped according to the Huang Tseng Classification (HTC). Their biochemical parameters, sensorium states and outcomes were recorded and analysed. Results: Twenty patients were reviewed (9 males). No mortality was recorded. 11 patients (55%) were treated conservatively with only intravenous antibiotics and eight patients underwent an intervention: minimally invasive with drain placement in six patients, and invasive in four patients (two underwent subsequent nephrectomy, and two patients had nephrectomy only). One patient left against medical advice. All patients had decreased serum creatinine levels and total leucocyte counts on discharge. Conclusion: EPN can be successfully managed conservatively for HTC Grade-1 and 2. Conservative treatment may be tried in higher grades, but poor response should lead to prompt escalation of treatment. doi: https://doi.org/10.12669/pjms.36.ICON-Suppl.1728 How to cite this:Irfaan AM, Shaikh NA, Jamshaid A, Qureshi AH.

A 63-year old Yemeni male, known case of endstage renal disease (ESRD), hypertension and diabetes mellitus, underwent craniotomy and endoscopic removal of an intraventricular mass. Peri-operatively he was started on cefazolin, a normal diet and regular hemodialysis without heparin. The international normalising ratio (INR) increased rapidly, reaching 4.2 on day five but responded equally rapidly to parenteral Vitamin K and withdrawal of cefazolin. Cefazolin is an antibiotic commonly used in clinical practice because of its long half-life, narrow spectrum and its ability for dose adjustment in renal failure patients. We review the literature, discuss the risk factors of its use and suggest possible mechanisms causing the prolonged coagulation.

Background Peutz-Jeghers syndrome is an autosomal dominant disease characterized by mucocutaneous pigmentation and hamartomatous polyps in the gastrointestinal tract (GIT). There have also been cases of extra GIT polyps such as the renal pelvis, urinary bladder, lungs and nares. Bladder hamartoma is an extremely rare finding, with only 12 cases described in the literature up to now. The rarity of the condition necessitates a comprehensive compilation of managements up to now so as to provide a better tool for the treatment of such conditions in the future. Case presentation A twenty-year-old male, known to have Peutz-Jeghers syndrome, presented to us complaining of obstructive urinary symptoms. A urethrogram done showed a filling defect at the base of the urinary bladder. The mass was resected transurethrally, and histopathology revealed a hamartoma of the bladder. The patient has since remained tumor-free on follow-up. Conclusions Transurethral resection of the bladder mass proved to be an effective therapy in this patient with no recurrence on the patient’s follow-up till now. There is still, however, a dearth of knowledge regarding the management of bladder hamartomas owing to the extreme rarity of the case.

Foreign direct investment (FDI) is investment that serves the business interests of the capitalist in an enterprise, which is in a different economy distinct from the investor's country of origin. FDI plays an unusual and growing part in world market. It can provide new markets and marketing channels, cheaper production facilities, access to new technology, products, dexterity and financing for businesses. For a host country or the foreign business which receives the investment, it can provide a source of state-of-theart technology, capital, processes, products, organizational technologies and management skills, and as such can provide a strong drive to economic development. In recent years, given rapid development and change in global investment approach, the definition has been broadened to include the acquisition of a lasting management interest in a company outside the investing company's home country. It may take many forms, such as a direct acquisition of a foreign firm, construction of a facility, or investment in a joint venture or strategic alliance with a local business with attendant input of technology, licensing of intellectual property. It produces a positive result on economic growth in host countries. Ironically, the presence of foreign companies in Pakistan predates the beginning of the country itself. Foreign investment and trade from the world, policy makers should consider the factors that attract multinational organizations to bring more investment in the economy and channelizing the investment in production sector to increase the turnover and employment. Inflows of investment in agriculture and textile sectors will increase the efficiency of these sectors and will resolve the food crises and employment issues in the economy.
