Interstitial pneumonia is an important complication of COVID-19 and a reliable negative prognostic factor. This study aimed to analyze the correlation between olfactory psychophysical scores and severity of lung involvement detected by chest computed tomography in COVID-19 patients suspected of having interstitial pneumonia. We also evaluated whether severity of respiratory disease predicted recovery of olfactory dysfunction .

As an alternative treatment to immediate surgical repair, endotracheal stent placement has been recently proposed in cases of iatrogenic tracheal damages.We report a case of a 91-year-old male who developed sudden subcutaneous emphysema during a total laryngectomy for laryngeal carcinoma. A tracheal tear at the distal third of the posterior tracheal wall was endoscopically assessed about 2 cm above the carina; CT confirmed the breach approximately 4 cm in length with associated pneumomediastinum and bilateral pneumothorax. Two covered self-expandable metal stents were then coaxially released under fluoroscopic control to cover the defect, restoring the tracheal integrity and leading to a normal thoracic appearance at CT and X-ray after 72 hours.

A wide range of surgical procedures are performed for either benign and malignant esophageal lesions, that may be classified as demolitive or conservative interventions. The former is characterized by resection and replacement of the esophagus with another organ, whereas conservative surgery is obtained preserving esophageal function without resection. Knowledge of surgical techniques and major complications is extremely important for a correctly performed radiographic study and a proper interpretation of the imaging findings. Functional evaluation of the operated alimentary tract and early detection of postoperative complications are essential for a successful recovery of esophageal surgery patients. We provide a brief overview of the main esophageal surgical procedures, reporting our experience on postoperative imaging of 104 patients submitted to surgery for either benign or malignant esophageal disease during a 6-year period.

Cardiac iathrogenic lesions can occur during diagnostic or therapeutic procedures. Resistance of the heart to an injury may cause a delay from the traumatic event to onset of the symptomatology or to heart rupture. We describe a rare case cardiac perforation with delayed rupture of the heart in a patient previously submitted to radiation therapy for breast cancer. Cardiocutaneous fistula at the cross-sectional computed tomographic and magnetic resonance imaging findings has not been previously reported, to our knowledge.

Background: The results on metabolic effects of the classical biliopancreatic diversion (BPD) have led us to investigate the operation without gastric resection, thus preserving stomach and pylorus, in patients who are not seriously obese but suffer from hypercholesterolemia, often associated with type 2 diabetes and hypertriglyceridemia. Methods: Between 1996 and 1999, we performed the duodenal switch (DS) without gastric resection on 24 mildly obese patients. Mean preoperative BMI was 36.2 kg/m2. 17 patients (70.8%) suffered from type 1 diabetes, 4 (16.6%) had impaired glucose tolerance, while the remainder had fasting hyperglycemia. In 20 patients (83.3%), hypercholesterolemia and alterations in lipid profile were present. Another 20 patients were taking drugs for arterial hypertension. The pluri-metabolic syndrome was present in 41.6% of patients. Results: Mean follow-up was 4 years. BMI reduction and weight loss were not large. 2 patients who had severe longstanding diabetes type 2 needed a second operation of the classical BPD because of failure in improving diabetes. Another 2 patients were changed to classical BPD because of a relapsing chronic duodeno-ileal ulcer. The incidence of ileal ulcer was 29.1%. Regarding hypercholesterolemia, hypertrigliceri-demia, and type 2 diabetes when there is a good pancreatic "reservoir", the operation seems effective in the long-term. Protein absorption is better than that obtained with the classical BPD. Conclusions: Our long-term results suggest that in carefully selected patients suffering from serious hypercholesterolemia or type 2 diabetes with insulin reserves still at an acceptable level, and with BMI 30-40, DS without gastric resection can be proposed as a surgical treatment for metabolic diseases but not for obesity.

The aim of this case report was to evaluate the usefulness of combined biliary and duodenal stenting in the palliation of pancreatic cancer. We report a series of 4 consecutive patients (2 men and 2 women, mean age 58.5 years, range 38-77 years) who underwent combined biliary and duodenal stenting in our department between March 2000 and April 2001. All patients had cancer of the head of the pancreas causing stricture of the common bile duct and second portion of the duodenum. Biliary and duodenal stents were successfully positioned, with relief of symptoms in all cases. No early complications were observed, except for a transient increase in serum lipase and amylase in one case. Mean follow-up was 7.5 months (range 5-14 months). One patient presenting recurrence of vomiting after 4 months because of tumour overgrowth at the distal edge of the prosthesis was successfully treated by insertion of a partially overlapping second coaxial stent. Combined biliary and duodenal stenting for the palliation of pancreatic cancer was performed safely and successfully. Stents allowed effective re-canalization of the biliary tract and duodenum, relieving both jaundice and vomiting. This procedure should be considered as an alternative to palliative surgery, especially in critically ill patients.

AIM: To assess the usefulness of self-expandable metal stents in the recanalization of cervical and/or hypopharyngeal strictures. MATERIALS AND METHODS: We report our experience in 10 patients with inoperable cervical and/or hypopharyngeal strictures treated by implantation of 11 uncovered self-expandable metal stents inserted perorally under fluoroscopic guidance. The stent was placed in the hypopharynx and cervical oesophagus in 3 patients and cervical oesophagus alone in 7. There were 8 men and 2 women, mean age 70.2 years, range 45–85 years. All patients but two had malignant stricture caused by squamous cell carcinoma, in one case there was a benign postoperative stenosis secondary to laryngectomy, and in the last patient a local recurrence from thyroid cancer. RESULTS: Eleven stents were placed in 10 patients: technical success was achieved in 9 cases while clinical improvement was obtained in 8 cases. Seven of ten patients had a rapid improvement of dysphagia. One patient had a distal misplacement of the prosthesis, while in the other two cases stent position was very proximal and interfered with swallowing. A mean 9-month follow-up was obtained (range 3–24 months). Four patients with malignant stricture developed proliferation of neoplastic tissue after 2–5 months. The only patient treated for a benign stricture developed inside proliferation of granulation tissue after 4 months. CONCLUSION: Despite several technical difficulties and a high rate of late complications, recanalization of cervical oesophageal strictures by self-expandable metal stents allowed good palliation of symptoms. Stents proved to be effective and well tolerated palliative treatment also for hypopharyngeal stenoses. S. Profili et al. (2002). Clinical Radiology 57 , 1028–1033.

Purpose: To assess the usefulness of stereotactic vacuum-assisted core breast biopsy (VCBB) performed using a stereotactic add-on device and film-screen technology with the patient in an upright seated position. Material and Methods: We reviewed a series of 129 women with non-palpable mammographic abnormalities who required stereotactic VCBB from December 1999 to November 2000. Twenty-seven (20.9%) cases were excluded due to difficulties in keeping the correct position during the procedure, while the other 102 (79.1%) underwent successful VCBB. Patients with lesions consisting of either atypical ductal hyperplasia or lobular carcinoma in situ were considered for excisional biopsy. Patients with either ductal carcinoma in situ or infiltrating breast cancer were referred for definitive surgery. The results of stereotactic VCBB were correlated to the subsequent surgical histology. Results: Stereotactic VCBB was interrupted because of bleeding in 1 case and vasovagal reaction in 5 cases. Two haematom...

We report the case of a 27-year-old woman with primary actinomycosis of the breast. Diagnosis was establishedby culture examination of specimen recovered by fine-needle aspiration cytology (FNAC) under ultrasound guidance. To our know-ledge, this is the first description in the literature of a case of primary actinomycosis of the breast caused by Actinomyces viscosus.Twenty-nine previous cases of primary actinomycosis of the breast have been published, but these were caused by the more com-mon species Actinomyces israelii. Targeted antibiotic therapy did not ameliorate the condition, thus drainage and excision of themass were carried out. No other medical therapy was administered. Six years after surgery, no recurrence has been observedon both ultrasonographic and mammographic examinations. ! Key Words: breast, fine-needle aspiration cytology, primary actinomycosis P rimary actinomycosis of the breast is a rare disease.Jain et al. (1), in a 1994 clinical review, wrote thatsince its first description by Ammentorp in 1893, 28 caseshave been reported and the details of 19 women are avail-able in the English-language literature. Later de Barroset al. (2) reported the first case of primary actinomycosis ina postmenopausal woman. All these rare cases of primaryactinomycosis were caused by

The use of a tracheo-esophageal voice prosthesis is a well-established procedure to restore the voice in total laryngectomees. The insertion of the prosthesis is not a risk-free procedure, various complications having been reported especially in irradiated patients. Here described is a case of an esophageal rupture after secondary tracheo-esophageal puncture with mediastinal abscess in a patient previously treated with pharyngo-laryngectomy and subsequent radiotherapy for a left pyriform sinus carcinoma, which required immediate surgical drainage through a left cervical approach. Few weeks after surgical drainage an esophageal stricture at the site of the rupture developed, which was only temporarily resolved after the insertion of biodegradable esophageal stents, followed by re-stenosis once the reabsorption of the stent took place.

Surgery of the large bowel includes many different intervention performed in the treatment of a wide spectrum of pathologies. Follow up imaging is needed particularly in patients with neoplastic and flogistic diseases. Contrast CT colonography is an emerging test which allows to obtain during a single examination an accurate assessment of large bowel wall, anastomotic and perianastomotic area, abdominal organs, nodes, and peritoneal cavity. In this chapter the most frequent normal and pathologic Contrast CT colonography pattern are showed.

Purpose: The purpose of this study was to examine the effect of periarticular injection of hyaluronate into shoulders with supraspinatus tendinosis under echographic guide. Methods and materials: The subjects were 56 patients with clinical, echographic and magnetic resonance diagnosis of supraspinatus tendinosis. They were divided in two groups by random sampling; 28 patients were assigned in SH group (sodium hyaluronate) and 28 patients in SC group (sodium chloride). The test drug was 20 mg sodium hyaluronate (2 ml, Hyalgan ® , Fidia SpA, Abano T., P.M. 500–700.000, 20 mg/2 ml). Results: Preliminary results showed that sodium hyaluronate presented the highest efficacy in the improvement of clinical symptoms and recovery of functional status in patients with supraspinatus tendinosis in fact the mean V.A.S. score (Visual Analogue Scale) at 1 month after the end of the infiltrative cycle was 8.0 in the SC group vs. 2.8 in SH group and these numerical data were substantially unchanged also after 3 and 4 months. Conclusion: Hyaluronate injection under echographic guide should be use not only as a lubricant but also to prevent articular cartilage degeneration and cover and protect the articular cartilage; indeed sodium hyaluronate can decrease inflammatory joint process. © 2007 Elsevier Ireland Ltd.

Urgent late complications of biliopancreatic diversion (BPD) are rare and often require the experience of a bariatric surgery team for their immediate resolution. The present work analyzes the incidence of emergency surgical conditions in a group of 138 patients who had undergone classical BPD, with a mean follow-up of 60 months (24–6) after BPD. Urgent surgical intervention was necessary in 9 patients out of 138 (6.5%): 7 (5%) were for intestinal obstruction (4 of the biliopancreatic limb and 3 of the alimentary tract); 2 (1.4%) were for stomal ulcer with complications (1 massive hemorrhage and 1 perforation). These complications of BPD are common to all GI operations, and thus are not specific to the type of surgery.We emphasize the importance of early diagnosis and treatment, particularly in regard to intestinal obstruction, because delay could have dramatic consequences.

To assess the effectiveness of airway stenting performed exclusively under radiological guidance for the palliation of malignant tracheobronchial strictures. We report our experience in 16 patients with malignant tracheobronchial stricture treated by insertion of 20 Ultraflex self-expandable metal stents performed under fluoroscopic guidance only. Three patients presented dysphagia grade IV due to esophageal malignant infiltration; they therefore underwent combined airway and esophageal stenting. All the procedures were performed under conscious sedation in the radiological room; average procedure time was around 10 min, but the airway impediment never lasted more than 40 sec. We obtained an overall technical success in 16 cases (100%) and clinical success in 14 patients (88%). All prostheses were successfully placed without procedural complications. Rapid clinical improvement with symptom relief and normalization of respiratory function was obtained in 14 cases. Two patients died within 48 hr from causes unrelated to stent placement. Two cases (13%) of migration were observed; they were successfully treated with another stent. Tumor overgrowth developed in other 2 patients (13%); however, no further treatment was possible because of extensive laryngeal infiltration. Tracheobronchial recanalization with self-expandable metal stents is a safe and effective palliative treatment for malignant strictures. Airway stenting performed exclusively under fluoroscopic view was rapid and well tolerated.

Background: The aim of the study is to evaluate the importance of age on the mid- and long-term results and complications after biliopancreatic diversion (BPD). Methods: Our study comprises 132 morbidly obese patients who underwent Scopinaro BPD from February 1995 to April 2001, with follow-up from 24 to 96 months. The patients, 53 males (40%) and 79 females (60%), with mean preoperative BMI 50.2 (35.4-81.5), and mean age 42 (20-65), were divided in 4 groups. Group A age 20-35, 43 patients; Group B age 36-45, 33 patients; Group C age 46-55, 31 patients and Group D age >55, 25 patients. Incidence of long-term specific complications after BPD were analyzed, including protein malnutrition, reversals, anastomotic ulcer, and incisional hernia. Results: Mean postoperative BMI was similar in all Groups. After 60 months the following BMI values were observed. Group A 30.8, Group B 34.9, Group C 35.9, Group D 32. Incidence of long-term complications were not significantly different (χ2) in the 4 Groups, and were respectively: protein malnutrition 6.9%, 12.1%, 6.4%, 16.0%; anastomotic ulcer 11.6%, 9%, 6.4%, 16.0%; reversal 2.3%, 9.0%, 1.32%, 8.0%; ventral hernia 34.8%, 45.4%, 54.8%, 32.0%. Conclusions: From the preliminary results, it appeared that the incidence of the complications was higher in group D (>55 years old), whereas group C (46-55 years old) showed a lower complication rate. However, the prevalence of complications in all groups was not statistically different on χ2 analysis. No age limit for bariatric surgery could be determined from the age ranges studied.

Background: To evaluate retrospectively the technical feasibility, safety and efficacy of radiofrequency thermal ablation (RFA) in the treatment of recurrent rectal cancer that is painful, non-resectable and no longer susceptible to radiotherapy and chemotherapy. Materials and Methods: Ten patients, average age 64 years, with pelvic recurrence of rectal carcinoma were treated with RFA to reduce pain and limit the progression of local disease. The lesion mean size was 4.7 cm(range of 3.2e9 cm). RFA was performed with computed tomography-guided percutaneous approach using local anaesthesia and conscious sedation in all patients. The therapeutic outcomes were evaluated by contrast- enhanced TC after 1, 3, 6 and 12 months. The absence of tumour enhancement on the TC image was considered to indicate complete tumour necrosis. Results: Complete tumour necrosis was found in 3 patients, sub-total in the remaining 7. Complete pain relief was obtained in 6 patients and a significant reduction of pain in the remaining patients (mean VAS score from7.4 before treatment to 1.5 after treatment). Abscess formation in the pre-sacral space and a bladder-rectal fistula after RF treatment was observed in 2 patients. The mean follow-up was 40 months (7–55months); 7 patients died of local tumour or distant progression. Three patients are still alive with 2 of them disease free. Conclusion: In selected cases, the RFA of pelvic recurrent rectal cancer can be considered a feasible and effective treatment in the control of pain and in the stabilisation of recidivism.
