RESUMEN
Cocaine abuse is known to have deleterious effects on multiple organ systems. Its effects on the cardiovascular system are well-established in the literature. The presence of a left ventricular thrombus (LVT) is a well-recognized complication of an anterior myocardial infarction, especially in patients with aneurysmal formation. There is a paucity of reports where cocaine use and LVT are associated with myocardial infarction and mesenteric ischemia simultaneously. Our patient is a 49-year-old female, who presented to our institution after ingesting a large volume of cocaine. She complained of abdominal pain, chest pain, and was eventually found to have a left ventricular mural thrombus with concomitant superior mesenteric artery ischemia, and renal and splenic infarcts. Administration of therapeutic anticoagulation resulted in the development of retroperitoneal hematoma resulting in a therapeutic dilemma.
RESUMEN
BACKGROUND: There is no consensus on the use of postoperative antibiotic prophylaxis (PAP) after mastectomy with indwelling drains. We explored the utility of continued PAP in reducing surgical site infection (SSI) rates after mastectomy without immediate reconstruction and with indwelling drains. PATIENTS AND METHODS: A multicenter, two-armed, randomized control superiority trial was conducted in Pakistan. We enrolled all consenting adult patients undergoing mastectomy without immediate reconstruction. All patients received a single preoperative dose of cephalexin within 60 min of incision, and postoperatively were randomized to receive either continued PAP using cephalexin (intervention) or a placebo (control) for the duration of indwelling, closed-suction drains. The primary outcome was the development of SSI within 30 days and 90 days postoperatively. Secondary outcomes included study-drug-associated adverse events. Intention-to-treat analysis was performed using multivariable Cox regression. RESULTS: A total of 369 patients, 180 (48.8%) in the intervention group and 189 (51.2%) in the control group, were included in the final analysis. Overall cumulative SSI rates were 3.5% at 30 days and 4.6% at 90 days postoperatively. PAP was not associated with SSI reduction at 30 (hazard ratio, HR 1.666 [95% confidence interval CI 0.515-5.385]) or 90 (1.575 [0.558-4.448]) days postoperatively, or with study-drug-associated adverse effects (0.529 [0.196-1.428]). CONCLUSIONS: Continuing antibiotic prophylaxis for the duration of indwelling drains after mastectomy without immediate reconstruction offers no additional benefit in terms of SSI reduction. There is a need to update existing guidelines to provide clearer recommendations regarding use of postoperative antibiotic prophylaxis after mastectomy in the setting of indwelling drains.

Schistosomiasis is rarely seen in Pakistan and is generally not very high on the list of differential diagnoses. However, it is an important cause of haematuria in certain endemic areas. It can affect multiple organs including the bladder, liver and lungs. We present a case of a young Pakistani male, travelling to and from Africa, who presented with complains of haematuria and suprapubic discomfort. Final pathologic diagnosis was urinary schistosomiasis (hematobium species). This case is particularly notable for the characteristic sago nodules identified on cystoscopy. It is important to consider schistosomiasis in the differential of haematuria in such scenarios as it confers significant morbidity if left untreated. Key Words: Schistosomiasis, Schistosoma hematobium, Haematuria, Urinary bladder.

Granulomatosis with Polyangitis (GPA) is an uncommon immunologically mediated necrotizing vasculitis affecting the small and medium sized systemic blood vessels. We previously reported our experience with this condition and herein, we document our study findings and compare them to the clinical and radiological findings of various studies from around the world. By doing so we hope to further create awareness of this condition afflicting not only our part of the population but is part of a larger global phenomenon.

Primary Myelofibrosis is a BCR-ABL negative myeloproliferative neoplasm with a variety of hematological presentations, including thrombosis, bleeding diathesis and marrow fibrosis. It is estimated to have an incidence of 1.5 per 100,000 people each year. Although JAK2 or MPL mutations are seen in PMF, several other mutations have recently been documented, including mutations in CALR, epigenetic regulators like TET, ASXL1, and 13q deletions. The identification of these mutations has improved the ability to develop novel treatment options. These include JAK inhibitors like ruxolitinib, heat shock protein-90 inhibitors like ganetespib, histone deacetylase inhibitors including panobinostat, pracinostat, vorinostat and givinostat, hypomethylating agents like decitabine, hedgehog inhibitors like glasdegib, PI3K, AKT and mTOR inhibitors like everolimus as well as telomerase inhibitors like imtelstat. Research on novel therapeutic options is being actively pursued in order to expand treatment options for primary myelofibrosis however currently, there is no curative therapy other than allogenic hematopoietic stem cell transplantation (ASCT) which is possible in select patients.

OBJECTIVE: To determine the outcome of patients receiving radioactive iodine therapy for toxic nodular goiter coming to Aga Khan University Hospital Karachi. METHODS: A total of 89 patients who visited the outpatient department of Aga Khan University Hospital from January 2010 to August 2017 were recruited for the study. Toxic nodular goiter was diagnosed on the basis of having hot nodule on thyroid scan with low TSH and high FT4/T4. Other demographic and laboratory data were also recorded. RESULTS: Eighty nine patients with toxic nodular goiter received a dose range from 10 to 30mCi RAI. Six months after RAI, 36.2% became hypothyroid, 38.5% became euthyroid while 25.3% remained hyperthyroid. Thyroid outcome at 3 months were correlating with 6 months results. CONCLUSION: Radioactive iodine therapy is a safe and effective way of treating toxic nodular goiter which usually results in cure of hyperthyroidism in majority of patients.
