Unveiling the Complexity of Nocardia Septic Arthritis in an Immunocompromised Patient: A Case Report.

Background: Nocardiosis is the systemic manifestation of Nocardia infection, often found in immunocompromised individuals. Nocardia are transmitted via inhalation or skin wounds, disseminating hematogenously to organs and rarely, joints. We present a patient with immunosuppression who developed gout of the knee with superimposed Nocardial septic arthritis and a possible subsequent systemic infection. Case Presentation: A 74-year-old man presented with left lower extremity swelling and pain. He was taking immunosuppressive medication for antineutrophilic cytoplasmic antibody-positive vasculitis. A week prior, an arthrocentesis test was positive for gout. He received prednisone without improvement. A repeat arthrocentesis was positive for Nocardia farcinica septic arthritis. Chest imaging showed subpleural nodules. After failed antibiotics, a susceptibilities test yielded results that favored linezolid. The patient exhibited acute anemia from hematomas intramuscularly above the infection, which resolved with transfusions. Immunosuppression was stopped, and the patient recovered appropriately after the correct antibiotics were administered. Conclusion: This case involves septic arthritis with possible pulmonary nodule involvement, showcasing the complexity of infections in immunocompromised individuals. Clinicians should maintain adequate suspicion for an infectious cause of arthritis in patients with immunosuppression. In our case, the hematomas are a curious finding, without known etiology. The question of when and how to reintroduce immunosuppressive agents while preventing the recurrence of nocardiosis remains a complex consideration.

A Rare Afferent Loop Syndrome Case in Adulthood Following Liver Transplantation in Neonatal Hemochromatosis.

Afferent loop syndrome, sometimes referred to as afferent limb syndrome, is an infrequent mechanical complication frequently observed following foregut surgeries involving the connection of the stomach or esophagus to the jejunum. This condition is commonly found in individuals who have undergone Billroth II reconstruction following a partial gastrectomy. Here, we present the first documented case of afferent loop syndrome in a patient with a medical history involving a liver transplant due to neonatal hemochromatosis.

Successful Endoscopic Treatment of a Pancreatic Pseudocyst in a Patient with Situs Inversus Totalis and Upper GI Duplication.

BACKGROUND Duplication of the gastrointestinal tract is a rare congenital malformation that can develop in any part of the digestive tract. These duplications may be asymptomatic into adult age. Situs inversus totalis is a rare congenital anomaly characterized by a mirror transposition of thoracic and abdominal organs. We present a case of a pancreatic pseudocyst in a patient with a combination of situs inversus totalis and doubling of the esophagus, stomach, and first part of the duodenum. CASE REPORT A 64-year-old woman presented with epigastric pain. Abdominal computed tomography revealed a pancreatic pseudocyst and a previously identified duplication of the esophagus, stomach, and duodenum with situs inversus totalis. The patient underwent esophagogastroduodenoscopy (EGD) with endoscopic ultrasonography for pseudocyst drainage. During EGD, a bifurcation of the esophagus was found. Duplication of the esophagus, stomach, and first part of the duodenum was evident on further advancement. A week later, there was repeated filling of the pseudocyst with a liquid component, and the patient underwent cystogastrostomy with stenting. Five months after discharge, the stent was removed without complications. CONCLUSIONS Duplication of the gastrointestinal tract and situs inversus totalis are very rare congenital malformations that require early diagnosis. While situs inversus totalis does not represent any medical disadvantage, physicians should be aware of abnormal anatomy before procedures to prepare specialists for this in case of the need for special techniques. Endoscopic treatment of pancreatic pseudocysts is safe and effective even in such rare cases. The use of endoscopic methods also minimizes intervention and decreases the length of the patients' stays in the hospital.

Asymptomatic colo-ovarian fistula amidst acute psychosis: a case report.

This paper presents a rare case of an asymptomatic colo-ovarian fistula in a 45-year-old female with acute psychosis and a history of bipolar disorder, seizure disorder and substance misuse. The intricate diagnostic challenges arising from the patient's complex medical history underscore the significance of a multidisciplinary approach. The absence of typical gastrointestinal symptoms and the presence of a tubo-ovarian abscess complicated the diagnosis of acute on chronic sigmoid diverticulitis and colo-ovarian fistula. Surgical intervention, including sigmoid resection, anastomosis and left salpingo-oophorectomy, led to successful resolution. This case highlights the need for further understanding of colo-ovarian fistula pathophysiology, improved diagnostic strategies, and the nuanced interplay between medical and psychiatric conditions in complex clinical scenarios.
