Metformin is well-known in the treatment of type 2 diabetes mellitus (DM). Metformin has become a drug of choice due to its affordability, cost-effectiveness, and established safety record. It primarily works by inhibiting hepatic gluconeogenesis. Common side effects include gastrointestinal issues, with rare complications, such as lactic acidosis and vitamin B12 malabsorption. This study discussed a 72-year-old male with type 2 DM who experienced recurrent nightmares upon initiating metformin, which ceased after discontinuation. The mechanism of metformin-associated nightmares remains poorly understood. Despite metformin\'s benefits, this case highlights the importance of recognizing rare adverse effects like nightmares, which can significantly impact patients\' quality of life.

Persistent sciatic artery (PSA) is a rare congenital vascular anomaly resulting from embryologic axial artery malformation in the lower limb. This case report presents three patients aged 45-60, each with bilateral PSA presenting with symptoms indicative of PSA complications, including aneurysmal degeneration, limb ischemia, thromboembolism, or neuralgia from nerve compression. It highlights the diagnostic process, management strategies, and clinical outcomes observed at a tertiary referral hospital. Treatment involved a collaborative, multidisciplinary approach with vascular surgeons, internists, and radiologists tailoring interventions to individual patient findings and disease progression. This report aims to provide insights into the diverse presentations and management of PSA in a resource limited setting, encouraging further reporting and case studies to enhance understanding of therapeutic outcomes.

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.

Bisphosphonates are widely used for a number of metabolic bone conditions. Orbital inflammation is a very rare side effect of bisphosphonate therapy that can risk permanent visual loss. We describe the complex case and successful treatment of a 79-year-old man who developed orbital cellulitis following the use of intravenous pamidronate disodium for severe hypercalcaemia. The challenges regarding the diagnosis of parathyroid carcinoma are also discussed.

Primary hydatid cysts (PHCs) in the extremities are uncommon, presenting in the majority of cases with atypical clinical features. Radical surgical excision remains the mainstay of treatment. The aim of our study was to accumulate the already published data on PHCs in the extremities in terms of demographic, diagnostic, and therapeutic aspects. Three electronic databases were meticulously searched for articles published until 2024. A total of 85 studies comprising 118 patients were finally included in our review. Sixteen patients (13.5%) were diagnosed with a hydatid cyst in their upper extremity, 94 (79.7%) with a PHC in the lower extremity, and eight (6.8%) with an echinococcal cyst in the axilla. Pain and swelling were the most frequent symptoms, whereas only two patients were completely asymptomatic. The mean lesion size was 11.6 ± 7.1 cm. Preoperative serology investigation was reported in 82 out of 118 (69.5%) patients; among them, 33 (44.6%) cases had a positive preoperative serology test. The vast majority of patients (96.6%) were treated with an interventional procedure either surgical or radiological, and only seven experienced postoperative complications. No anaphylactic reaction was described perioperatively. Although preoperative diagnosis of PHCs is challenging, they should be considered in the differential diagnosis of soft tissue lesions. Treatment strategies should be individualized on a patient basis, while radical surgical excision remains the gold standard treatment.

Lymphangiomas are rare benign cystic tumors. Surgical excision is the primary treatment, aiming for complete removal. Diagnosis relies on imaging and histological confirmation. Malignant transformation is exceptionally rare. We report a 25-year-old man admitted for peri-umbilical abdominal pain and an abdominal mass. Imaging revealed multilocular peritoneal cystic formations with infiltration of adjacent mesenteric fat. Laboratory findings were unremarkable, and exploratory laparotomy was performed. A voluminous cystic mass originating from the mesentery was discovered, requiring intestinal sacrifice for complete resection. Immediate postoperative recovery was smooth. Pathological analysis confirmed the diagnosis of mesenteric cystic lymphangioma. The patient had a favorable outcome with no tumor recurrence at a three-year follow-up. We emphasize the significance of complete surgical removal to prevent complications associated with cystic lymphangioma and reduce the risk of recurrence.

Nuclear protein in testis (NUT) carcinoma is a rare neoplasm arising mainly from midline structures. It is an aggressive type of carcinoma associated with poor survival despite the use of multiple treatment modalities. Here, we present a case of a 17-year-old paediatric patient with NUT carcinoma of larynx, which is even rarer among all reported cases. The patient underwent surgery followed by radiotherapy and systemic treatment and he died 15 months after the diagnosis. The management of this rare disease requires further investigation.

Shewanella putrefaciens is an opportunistic pathogen rarely responsible for human infection. However, it has been reported that it causes skin and soft tissue infections and bacteremia in immune-compromised patients, such as cellulitis, abscesses, bacteremia, and wound infection. It is an oxidase and catalase-positive non-fermenter gram-negative rod that produces hydrogen sulfide. We report the case of a 90-year-old woman, who presented an invasive infectious burn wound associated with Shewanella putrefaciens bacteremia. She was admitted into the burn center of the military hospital M.S Nekkache of Algiers, suffering from 40% TBSA with a history of diabetes. After one week of admission, the patient complained of a high fever. Microbiological culture of the catheter tip was positive and showed pale colonies on the MacConkey agar, non-lactose fermenting plate. Nutritive agar medium culture showed red pale tan colonies with a concentration >103 CFU. Identification and antibiotic susceptibility were obtained by the Phoenix system (Becton-Dickinson, USA) as Shewanella putrefaciens. This was confirmed by standards and semi-automated microbiological techniques. Gram stain showed Gram-negative bacilli with positive oxidase and catalase reactions. Production of hydrogen sulfide was confirmed by the semi-automated API 20NE method (biomerieux, France). The isolate was resistant to gentamicin, amikacin, ceftazidime, aztreonam, amoxicillin- clavulanic acid, cefepime, trimethoprim/sulfamethoxazole, and nitrofurantoin. In our case, S. putrefaciens was found in a mixed culture with Klebsiella pneumoniae. No earlier exposure of the patient to marine water had been noticed. Blood culture indicated colonies growth of Acinetobacter baumannii. No further isolation of this bacteria was noticed after treatment. The patient was given imipenem, vancomycin and colistin. Despite our best efforts, the patient could not be saved because of sepsis and renal function failure.
Shewanella putrefaciens est une bactérie opportuniste, rarement responsable d’infections humaines. Elle a toutefois été rapportée comme cause d’infections de la peau et des tissus mous (cellulites, abcès, surinfections de plaies) et de bactériémies chez des patients immunodéprimés. C’est un bacille à Gram négatif non fermentant, oxydase et catalase +, producteur de sulfure d’hydrogène. Nous présentons le cas d’une patiente diabétique de 90 ans ayant subi une bactériémie issue d’une surinfection de brûlure à Shewanella putrefaciens. Elle était hospitalisée dans l’hôpital militaire MS. Nekkache d’Alger à la suite d’une brûlure touchant 40% SCT. Une fièvre élevée a été constatée à J7. La culture de l’extrémité distale du cathéter montrait, sur gélose de McConkey, des colonies pâles non fermentantes. Sur milieu enrichi, on observait >103 CFU rouge pâle, identifiées à Shewanella putrefaciens par le système Phoenix (Beckton-Dickinson), identification confirmée par les techniques microbiologiques standard et semi- automatiques. La coloration de Gram était négative, les réactions catalasique et oxydasique étaient positives. La production de sulfure d’hydrogène était par API 20NE semi- automatique (BioMérieux). La bactérie résistait à gentamicine, amikacine, ceftazidime, aztréonam, amoxicilline- acide clavulanique, céfépime, triméthoprime- sulfaméthoxazole et nitrofurantoïne. Shewanella putrefaciens était associée à Klebsiella pneumoniæ et les hémocultures poussaient à Acinetobacter baumannii. Il n’y avait pas de notion d’exposition antérieure à l’eau de mer. La bactérie n’a pas été retrouvée après traitement par imipénème, vancomycine et colimycine. La patiente est toutefois décédée de sepsis et insuffisance rénale aiguë.
