Infant formulas are meant to be used until 1 year of age, at which point children are transitioned to non-infant formulas or cow\'s milk, depending on their remaining dietary intake. Noninfant formulas and cow\'s milk are appropriate for children who have an average weight at that 1-year mark (9-9.5 kg); however, can contribute significant protein and/or electrolytes to children who are underweight for age, particularly if they still rely heavily on formula feeding for their caloric intake. In this short communication, we present several cases of patients who received excessive amounts of nutrients for age following the formula transition at the 1-year mark. We also provide recommendations for clinicians to consider when faced with underweight infants who are meant to be transitioning off infant formulas.

Iatrogenic injury of the bladder is a rare incidence during inguinal hernia repair in children, with serious consequences for such patients. Due to the scarcity of information on this matter, it is our goal to share our experience regarding the therapeutic approach to such a rare occurrence. Specifically, a 22-month-old male was admitted to our department with the complaint of vomiting, abdominal pain and anuria, two days after inguinal hernia repair. The child had distention of the inguinal hernia region and was lethargic. The diagnostic investigation did not reveal any significant findings. During surgical exploration, we discovered an injury to the bladder, while a large part of the dome of the bladder was ligated and subsequently became necrotic. After a reoperation and an enduring postoperative course, the patient finally recovered. Currently, the child is under observation. Therefore, it is of paramount importance for pediatric surgeons to be acquainted with the potential for bladder injury during inguinal hernia repair, ways to manage this complication, and various issues that may emerge during the therapeutic process.

UNASSIGNED: To investigate short- and intermediate-term outcomes of immediate (on table) recognition and surgical treatment of iatrogenic acute type A aortic dissection (ATAD) that occurred during the course of the cardiac surgical procedures.
UNASSIGNED: Of 23,143 adult patients undergoing cardiac surgical procedures at our institution from January 2016 to December 2020, 21 (0.09%) suffered from intraoperative iatrogenic ATAD and underwent immediate aortic repair. Their clinical characteristics, in-hospital outcomes and follow-up results were analyzed.
UNASSIGNED: Among the 21 patients, 13 (61.9%) suffered from hypertension, and 14 (66.7%) had a dilated ascending aorta. In-hospital mortality was 9.5%, and new onset of permanent neurologic deficit was recorded in one patient. During a median follow-up of 36.0 months, all 18 follow-up patients survived without repeated surgeries. A follow-up computed tomography (CT) examination revealed a residual false lumen in the aortic arch in 3 patients and in the descending aorta in 8, with residual false lumen perfusion in one.
UNASSIGNED: Immediate recognition and surgical repair of ATAD that developed as a complication during cardiac surgical procedures are associated with low mortality and high intermediate-term survival.

This report describes the case of a frail 36-year-old patient who underwent an endovascular treatment of a right subclavian artery pseudoaneurysm (SAP) associated with an arteriovenous fistula secondary to a traumatic central venous catheter insertion. The deployment of a covered stent from the innominate to the right common carotid artery combined with coiling of the SAP and the internal mammary artery was performed. Two additional covered stents were deployed from the vertebral artery to the distal subclavian artery to preserve right upper extremity circulation. This case highlights the feasibility of an endovascular treatment of a complex SAP in a candidate unsuitable for open surgery.

A 47-year-old male, a known case of alcoholic chronic liver disease with portal hypertension, presented with complaints of abdominal distension and shortness of breath. A provisional diagnosis of ethanol-related compensated chronic liver disease (CLD) with portal hypertension and splenomegaly, gross ascites with bilateral hepatic hydrothorax was made. The left-sided pleural effusion subsided after three pleural taps, but the right-sided effusion kept refilling even after four to five days of repeated therapeutic taps, so a pigtail catheter was left in situ. The pleural fluid was sent for culture which did not grow any pathogenic organisms. Cartridge-based nucleic acid amplification tests where Mycobacterium tuberculosis complex (MTBC) was not detected, Ziehl-Neelsen staining was done in which acid-fast bacilli were not seen, and cytology was done where no malignant cells were seen. The patient was discharged with the pigtail in situ on the right side and, after 20 days, the patient again presented with shortness of breath, and imaging revealed moderate right-side pleural effusion. Draining of pleural fluid was done and sent for investigation which again revealed no infective etiology. The patient was admitted to the hospital for one month as the right-sided effusion did not resolve. Suddenly, the patient developed shortness of breath, and a chest X-ray was done, which showed pigtail blockage; pigtail flushing was done, and the bag was drained. The patient was empirically started on IV meropenem 500 mg TID, IV teicoplanin 400 mg BD, and inj polymyxin B 500,000 IU IV BD. The pleural fluid was sent continuously for investigation for the first two months which again did not reveal any infective etiology. After two months of pigtail in situ, the pleural fluid was sent for CBNAAT where MTBC was not detected, and ZN stain showed smooth acid-fast bacilli. The sample was cultured, and it grew acid-fast bacilli in 72 hours on blood agar, MacConkey agar, and Lowenstein-Jensen media. A line probe assay done from the isolate revealed it to be Mycobacterium abscessus subsp. abscessus which was resistant to macrolides and sensitive to aminoglycosides. Mycobacterium abscessus subsp. abscessus was isolated from repeated cultures of pleural fluid, and the patient was advised on a combination treatment of amikacin, tigecycline, and imipenem. The patient was discharged with the indwelling pigtail with the advised treatment; unfortunately, we lost patient follow-up as the patient never returned to us.

In this editorial we comment on the article by Emara et al published in the recent issue of the World Journal of Gastrointestinal Surgery. Previously, surgery was the primary treatment for bile duct injuries (BDI). The treatment of BDI has advanced due to technological breakthroughs and minimally invasive procedures. Endoscopic and percutaneous treatments have largely supplanted surgery as the primary treatment for most instances in recent years. Patient management, including the specific technique, is typically impacted by local knowledge and the kind and severity of the injury. Endoscopic therapy is a highly successful treatment for postoperative benign bile duct stenosis and offers superior long-term outcomes compared to surgical correction. Based on the damage features of BDI, therapeutic options include endoscopic duodenal papillary sphincterotomy, endoscopic nasobiliary drainage, and endoscopic biliary stent implantation.

An abnormal connection between the carotid artery and cavernous sinus is referred to as a carotid cavernous fistula (CCF). A direct CCF results when the connection occurs between the intracranial internal carotid artery (ICA) and the cavernous sinus. These events are typically the result of a head injury, but can also be iatrogenic, resulting from various intracranial procedures. Direct CCF occurrences rarely heal spontaneously due to the high flow rate across the fistula. In this report, we present an uncommon case involving a delayed iatrogenic direct CCF, which developed following the placement of a pipeline flow-diverting stent that was used to treat a cerebral aneurysm. Interestingly, this unusual iatrogenic direct CCF subsequently spontaneously resolved within a few months. To our knowledge, this is the only case of a delayed CCF occurring with the use of a flow-diverting sent, which then resolved on its own. This report recounts our experience with the case.

UNASSIGNED: Ureteric injuries are not uncommon in obstetric and gynaecologic surgeries. Some specific procedures predispose to these injuries. Recognition is often delayed. This study aims to present a single-center experience on the presentation, risk factors, and management of ureteric injuries.
UNASSIGNED: We retrospectively reviewed case files of patients primarily presenting or referred to our urology division with ureteric injuries following obstetrics or gynaecologic surgeries from June 2005 to May 2015. Data extracted included the time of presentation or recognition, the specific offending surgery, the laterality, and site involved, the repair performed, and outcome.
UNASSIGNED: Twenty-three patients had injuries (with a total of 25 ureters involved owing to 2 bilateral injuries). Caesarian-section is the commonest offending surgery in 13 (56.5%). The reasons for early recognition were sudden anuria in two and urinary leakage in the operating field in four patients constituting 26.0%, while 17 (74.0%) were recognized in the post-operative period. Urinary fistulae were the commonest presentation in 13 (76.5%) patients recognized postoperatively. Transection and ligation are the commonest mechanisms of injury. The distal third was the site involved in all patients, while ureteroneocystostomy alone was the most predominant repair in 18 (72.0%). Ureteroneocystostomy with Psoas hitch and Boari flap reconstruction was offered in six (24.0%) suggesting greater than5cm ureteral loss.
UNASSIGNED: Ureteric injuries often occur following obstetrics and gynaecologic surgeries. Caesarian-section is the commonest predisposing surgery in our center. Prompt recognition and repair is recommended.

Kaposi\'s sarcoma (KS), linked to human herpesvirus 8 (HHV8), manifests in various clinical forms with iatrogenic KS uniquely tied to immune dysregulation induced by medical interventions. This study describes a 58-year-old male of sub-Saharan origin with a medical history of segmental and focal hyalinosis treated with methylprednisolone and mycophenolate mofetil. The patient developed skin lesions on both thighs, accompanied by post-prandial vomiting and abdominal pain. Clinical examination revealed flesh-colored nodules on the thighs and inguinal lymphadenopathy. Biopsy confirmed the diagnosis of KS, exhibiting positive nuclear labeling to anti-HHV8 and negative HIV serology. Additionally, radiological findings from the thoracic-abdominal-pelvic computed tomography (CT) scan significantly contribute to our understanding of the multiorgan involvement associated with KS in this case, providing valuable insights for diagnosis and therapeutic considerations. This case highlights the iatrogenic subtype of KS, linked to immunosuppression from prior medical interventions. Notably, gastrointestinal involvement was evident, with lesions in the stomach and small intestine. Intravenous paclitaxel administration resulted in a positive clinical response. This study underscores the importance of clinical vigilance, endoscopic evaluation, and early intervention in the nuanced diagnosis and management of iatrogenic KS.
