Gangrene of the Foot After Coronary Artery Bypass Graft Surgery.

Coronary artery bypass grafting (CABG) is the most common surgery performed by cardiothoracic surgeons worldwide. Risks of CABG include neurological outcomes, deep vein thrombosis, renal or gastrointestinal injury, and death. Perioperatively, some patients may need intra-aortic balloon pump (IABP) use to help assist with cardiac function. In this case, a 75-year-old man presented with multivessel myocardial infarction requiring IABP for cardiac assistance prior to undergoing CABG. Eighteen days after his CABG, his toes turned black at home. A CT angiogram showed aortic atherosclerosis, right tibioperoneal trunk stenosis, mild atherosclerotic right proximal anterior tibial artery stenosis, and multifocal occlusive lesions in the right and left infrapopliteal vessels. Vascular surgery performed balloon angioplasty of the right anterior tibial artery and podiatry performed a transmetatarsal amputation of the dry gangrene. The aim of this case report is to present a rare complication of CABG with peri-operative IABP use and to highlight the need for prompt diagnosis and treatment of dry gangrene.

Mixed Serous and Clear Cell Adenocarcinoma of the Ovary Presenting with Symptomatic Hypercalcemia: A Case Report and Clinical Considerations.

INTRODUCTION: Hypercalcemia is a common phenomenon in patients with cancer but is more common among certain cancer types. Hypercalcemia in ovarian cancer is the common presenting sign in small cell carcinoma of the ovary, hypercalcemic type; however, there are no known documented cases of hypercalcemia as the presenting sign for mixed serous and clear cell adenocarcinoma. This case report describes symptomatic hypercalcemia as the presenting sign of mixed serous and clear cell carcinoma of the ovary. CASE PRESENTATION: A 60-year-old woman with a medical history of hypertension and hyperlipidemia presented to the outpatient clinic with weakness, nausea, emesis, constipation, and an unintended 9-kg (20-lb) weight loss. Her calcium level was elevated at 15.7 mg/dL (reference range = 8.5-10.3 mg/dL). She was treated for hypercalcemia and subsequently admitted to the hospital 4 times because of recurrence of symptoms. On outpatient workup, she was noted to have an abnormal positron emission tomography scan showing intense activity in the uterus consistent with malignancy. An exploratory laparotomy with total abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy, and lymph node staging was performed, and pathologic findings demonstrated high-grade ovarian carcinoma with serous and clear cell features. DISCUSSION: Hypercalcemia is a rare but possible primary presenting symptom of ovarian cancer. In these patients, serum calcium measurements could possibly serve as a tumor marker for disease.

Concurrent Birt-Hogg-Dubé Syndrome and Hereditary Paraganglioma-Pheochromocytoma Syndrome Presenting as Metastatic Renal Cell Carcinoma in a 25-Year-Old Man: A Case Report.

INTRODUCTION: Birt-Hogg-Dubé syndrome and hereditary paraganglioma-pheochromocytoma syndrome are rare genetic cancer syndromes that predispose patients to renal neoplasia. We report a case of a 25-year-old man with both Birt-Hogg-Dubé syndrome and hereditary paraganglioma-pheochromocytoma syndrome who presented with painless gross hematuria and was found to have metastatic clear cell renal carcinoma. CASE PRESENTATION: A previously healthy, 25-year-old man presented to his outpatient primary care physician with painless gross hematuria. Urinalysis results demonstrated hemoglobinuria, and serum chemistry results demonstrated a creatinine level of 1.61 mg/dL (baseline of 0.96 mg/dL). A computed tomography scan showed that the patient had a left renal mass, renal vein thrombosis with inferior vena cava extension, and nodal and hepatic metastasis. Biopsy specimens of the left renal mass and liver demonstrated clear cell carcinoma. The patient underwent cytoreductive nephrectomy, caval thrombectomy, and partial colectomy with reanastomosis. He received palliative therapy with 1 mg/kg of ipilimumab and 3 mg/kg of nivolumab for 4 cycles. CONCLUSION: To our knowledge, this is the first known case report to date documenting a patient with concurrent Birt-Hogg-Dubé syndrome and hereditary paraganglioma-pheochromocytoma syndrome. This case demonstrates the exceptionally young presentation of metastatic renal cell carcinoma with this genotype.

Endogenous Group A Streptococcal Endophthalmitis in a Healthy 42-Year-Old Man: A Case Report.

INTRODUCTION: Endogenous endophthalmitis is a rare condition that is caused by hematogenous spread of bacteria or fungi and is usually seen in patients with predisposed medical conditions. We are reporting an unusual case of group A streptococcal infection causing endogenous endophthalmitis and septic arthritis in a healthy 42-year-old man. CASE PRESENTATION: A previously healthy 42-year-old man presented to the Emergency Department with chills, fever, left wrist pain, left eye pain, and vision loss. Owing to the acute onset of the septic arthritis and the patient's bandemia, the Ophthalmology Department was consulted for suspicion of endophthalmitis. Blood cultures, left wrist synovial fluid cultures, and vitreous cultures grew group A streptococcus. An incision and drainage of the left wrist was performed, and intravitreal injection of vancomycin was given. The patient's vision was responsive only to light on discharge from the hospital. The patient underwent a left eye evisceration 2 months later. DISCUSSION: Endophthalmitis provides a difficult diagnostic and therapeutic challenge. However, even with prompt treatment, visual outcomes may be poor.

Duodenal adenocarcinoma might be the cause of intractable nausea and vomiting in patient with coeliac disease.

Coeliac disease (CD) is an autoimmune disorder which leads to chronic inflammation of the gut. Untreated CD is associated with upper gastrointestinal malignancies, Small-bowel lymphoma and adenocarcinoma are recognized complications of untreated coeliac disease (CD). We report the case of a 43-year-old male suffering from CD who was treated with a gluten-free diet one year, presenting with complaints of intractable nausea and vomiting. After several studies, He underwent push enteroscopy, which identified one large mass lesion in the third part of duodenum. However, histopathological examination showed adenocarcinoma. Subsequently, a duodenal segment resection was performed. After surgery, the patient recovered well and left our hospital in good condition. Clinicians should take into small bowel adenocarcinoma is rare but associated with CD particularly in CD patients with worrying symptoms such as nausea and vomiting unresponsiveness to treatment and these patients should be screened for long term complications like malignancy.
