BACKGROUND Perioperative chemotherapy improves survival in patients with advanced esophagogastric cancer, but the optimal treatment regimen remains unclear. More intensive chemotherapy may improve outcome, but also increase toxicity and complications. METHODS A total of 843 patients were included in this retrospective study and stratified in 4 groups: doublet therapy with cisplatin or oxaliplatin and 5-fluorouracil (groups A/B) or triplet therapy with additional epirubicin or taxane (groups C/D). The influence of the different neoadjuvant chemotherapy regimens on response, prognosis, and complications was assessed. RESULTS Clinical and pathological response were associated with longer overall survival (OS; p < 0.001). No significant differences regarding response or OS were found, but there was a trend toward better outcome in group D (taxane-containing triplet). In the subgroup of 669 patients with adenocarcinomas of the esophagogastric junction (AEG), patients who had received taxane-containing regimens had a significantly longer OS (p = 0.037), but taxane use was not an independent factor in multivariate analysis. Triple therapy with taxanes did not result in a higher complication rate or postoperative mortality. CONCLUSIONS Although no superior neoadjuvant chemotherapy regimen was identified for patients with esophagogastric adenocarcinoma, taxane-containing regimens should be further investigated in randomized trials, especially in patients with AEG tumors.

A 39-year-old white man presented with a swollen left upper eyelid secondary to progressive acute bacterial rhinosinusitis (ABRS). Physical examination found a 40% reduction in vision in the left eye and right-sided erythematous temporal swelling with tenderness to palpation. Computed tomography revealed the presence of an inflammatory lesion in the left orbit. Duplex ultrasonography demonstrated a thrombotic occlusion in the right superficial temporal vein (STV). For treatment of the complicated ARBS, the patient received intravenous antibiotics and underwent surgery. The STV thrombophlebitis was treated with low-molecular-weight heparin. Postoperatively, the patient recovered completely and his vision normalized; 10 days later, duplex ultrasonography showed a patent STV. The development of contralateral STV thrombophlebitis is conceivably facilitated by venous anastomoses of the scalp in the front of the head. As a result, embolic spread would be a possible complication of infectious ABRS foci communicating with intraorbital and pericranial veins. To the best of our knowledge, this is the first reported case of such a complication of ARBS in the literature.

Technical complications in implant prosthetic cases represent a major challenge in dentistry. This case report describes minimally invasive management to recover an implant with a fractured remnant of a zirconia abutment, including provisional rehabilitation during a sequential treatment protocol in the esthetic zone. A patient was treated with a screw-retained one-piece implant-supported reconstruction made of a customized zirconia abutment with direct ceramic veneering in the maxillary right central incisor position. During the prosthetic try-in, a fracture in the apical portion of the abutment was evident. The first rescue attempt led to fracture of the retrieval instrument. Immediately, an individualized wired construction was applied to bond the existing fractured reconstruction to the neighboring teeth to maintain the peri-implant mucosal architecture. Because the implant screw canal was blocked, a customized round bur had to be manufactured and was placed in the implant axis with a specific bracket tool from the service set to protect the interior implant threads. Then, the drills of the service set were guided by the newly created access to remove the fractured remnants. The implant screw was retapped and the area rinsed with chlorhexidine solution. All remnants were removed without the need for surgical intervention. Neither the implant connection nor the bone-to-implant interface was damaged. The stepwise treatment approach with the customized round bur combined with the system-specific drills of the service set saved the blocked implant so that the patient could be successfully rehabilitated with a new implant reconstruction.

Placenta previa is alleged to be more common among women with a history of prior induced abortion. To investigate further whether there is a relationship between previous induced abortion and subsequent pregnancy complication of placenta previa, a matched case-comparison study was conducted comparing the reproductive histories of 256 women with placenta previa matched on age, date of delivery, and hospital with those of 256 women having normal deliveries and cesarean section deliveries without placental complications.^ Women with placenta previa had a twofold increase in the odds of having had one previous induced abortion (odds ratio 2.25) over women with no placental complications. Women with placenta previa and two or more previous induced abortions had a sevenfold increase in odds.^ The significant association of placenta previa and previous induced abortion remained after including gravida status, previous dilatation and curettage (D&C) status, previous spontaneous abortion, and race in a conditional logistic regression model. There is interaction between high gravidity and previous spontaneous abortion. Dilatation and curettage is associated with placenta previa primarily because women with abortion histories have also had a dilatation and curettage.^ Women who are seeking abortion and wish to have children later should be informed that there may be a longterm effect of developing placental complications in subsequent pregnancies. Women who have had at least one induced abortion or any dilatation and curettage procedure should be monitored carefully during any subsequent pregnancy for the risk of the complication of placenta previa. This knowledge should alert the physician or nurse-midwife to treat those women with a history of previous induced abortions as potential high risk pregnancies and could perhaps reduce maternal and fetal morbidity rates. ^

We describe a case report of a patient that was implanted with a posterior chamber phakic intraocular lens (Phakic Refractive Lens, PRL) for the correction of moderate myopia and who developed postoperatively a fixed mydriasis compatible with an Urrets-Zavalia Syndrome (UZS). Specifically, a sudden acute increase of IOP in the left eye was observed in the immediate postoperative period. After IOP stabilization, the refractive result was good, but a fixed and mydriatic pupil appeared. This condition led the patient to experience visual discomfort, halos, and glare associated with high levels of higher-order aberrations in spite of the good visual result. A tinted-contact lens was fitted in order to minimize those symptoms. The UZS should be considered as a possible complication after implantation of posterior chamber phakic intraocular lenses.

Aim. To describe the subsequent treatment of airway trauma sustained during laryngoscopy and endotracheal intubation. Methods. A rare injury occurring during laryngoscopy and endotracheal intubation that resulted in perforation of the tongue by an endotracheal tube and the subsequent management of this unusual complication are discussed. A 65-year-old female with intraparenchymal brain hemorrhage with rapidly progressive neurologic deterioration had the airway secured prior to arrival at the referral institution. The endotracheal tube (ETT) was noted to have pierced through the base of the tongue and entered the trachea, and the patient underwent operative laryngoscopy to inspect the injury and the ETT was replaced by tracheostomy. Results. Laryngoscopy demonstrated the ETT to perforate the base of the tongue. The airway was secured with tracheostomy and the ETT was removed. Conclusions. A wide variety of complications resulting from direct and video-assisted laryngoscopy and tracheal intubation have been reported. Direct perforation of the tongue with an ETT and ability to ventilate and oxygenate subsequently is a rare injury.

We report a case of a 24-year-old woman who was delivered via cesarean section at 39 weeks and presented in the puerperium with symptoms of worsening abdominal pain and septicaemia. Preoperative ultrasonography suggested the presence of a pelvic collection. Explorative laparotomy revealed the simultaneous presence of Meckel's diverticulitis and appendicitis without bowel perforation. The patient made an uneventful recovery following small bowel resection with end to end reanastomosis and appendicectomy.

Objectives: We report a case of a frail older adult affected by Chilaiditi syndrome complicating transthoracic lung biopsy, which has never been presented before in the literature. Materials and methods: After illustration of our case, we review the available literature about Chilaiditi syndrome. Results: Chilaiditi syndrome is a rare disease characterised by the interposition of colonic segments between the liver and diaphragm associated with mild to severe clinical symptoms. Conclusion: Although it is uncommon, Chilaiditi syndrome is a clinical condition that should be recognized early and differentiated from other diseases since it may significantly impair a patient’s prognosis.

A 61-year-old man presented with high fever, and severe back and abdominal pain following transrectal ultrasonography (TRUS)-guided prostate biopsy. Diagnosis of spondylodiscitis and psoas abscesses was made based on MRI images of the lumbar tract of the spine. Six-month broad-spectrum antibiotic treatment and immobilization with a girdle overcame the disease without any relapse at the 1-year follow-up. Spondylodiscitis after TRUS-guided prostate biopsy is a rare event, which is not yet included as a major complication of the procedure. It is probably due to the presence of fluoroquinolone-resistant bacteria in faeces. It is, therefore, important to highlight this possibility and to stress the use of targeted antibiotic prophylaxis after rectal flora swabbing with selected antibiotics at sufficient concentrations to be effective.

Acute cholecystitis after colonoscopy is a rare event, with less than 10 cases described in the literature. We report the case of a male patient with silent gallstones who underwent colonoscopy for follow-up of his Crohn’s disease. The colonoscopy revealed erosions in the terminal ileum, from which biopsies were taken. A sessile polyp 4 mm in diameter at the recto-sigmoid junction was also removed. Less than 24 h after the colonoscopy, the patient complained of upper right quadrant pain, nausea and vomiting. Based on the clinical findings, laboratory data and ultrasonography, we diagnosed acute cholecystitis and excluded any complication after the colonoscopy. Laparoscopic cholecystectomy was performed and the patient was discharged.
