Types of morbidity presenting in frontline-bordering regions of Ukraine: the experience of deploying additional mobile medical units.

INTRODUCTION: On 24 February 2022, the full-scale military invasion of Russia into Ukraine has started, creating one of the largest humanitarian crises in Europe since the World War II. As of 27 July 2022 (by the time when the most of Russian advances have already occurred), more than 900 healthcare facilities in Ukraine were damaged and 127 hospitals were destroyed completely. METHODS: Mobile medical units (MMU) were deployed in the frontline-bordering areas. An MMU included a family doctor, a nurse, a social worker and a driver, and aimed to provide medical help in remote areas. 18 260 patients who received medical help in MMUs in Dnipro (Dnipro city) and Zaporizhia (Zaporizhia city and Shyroke village) oblasts from July until October 2022 were included in the study. The patients were subdivided by month of visit, area of residence and area of MMU operation. Patients' sex, age, date of visit and diagnosis were analysed. Comparison between groups was performed using analysis of variance and Pearson's χ2 tests. RESULTS: Majority of patients were females (57.4%), people aged 60+ years (42.8%) and internally displaced persons (IDPs) (54.8%). The proportion of IDPs increased from 47.4% to 62.8% over the period of study (p<0.01). The most common cause of visit to doctors was cardiovascular diseases (17.9%). The frequency of non-respiratory infections remained stable over the period of study. CONCLUSIONS: In the frontline-bordering areas of Ukraine, females, people older than 60 years and IDPs more frequently sought medical help in MMUs. Causes of morbidity in the studied population were similar to the causes of morbidity before the beginning of full-scale military invasion. Maintaining continuous access to healthcare services may be beneficial for the patient outcomes, especially in terms of cardiovascular disease.

Platinum compounds and sodium metabolism in children with diencephalic glioma.

In this brief report we have described eight children affected by optic pathway/hypothalamus gliomas and treated with carboplatin and/or cisplatin, which developed a derangement of sodium and water metabolism, due to diabetes insipidus (DI) or to syndrome of inappropriate antidiuretic hormone secretion (SIADH) after surgical resection. In four out of these eight patients the treatment with platinum compounds produced prolonged haematological toxicity and in five out of them it caused neurosensorial bilateral hypoacusia. In addition cisplatin worsened electrolytes disturbances. Hence children with DI or SIADH should be carefully monitored before, during and after the treatment with platinum compounds.

Experimental research and surgery: why, how, and when?

Experimental research faces two great problems: the significant reduction of public funding and the firm opposition of the public opinion. The law forbids the use of large animals, so that it is possible to use small animals only, which require microsurgical techniques. However, even a skillful surgeon does not know how to perform microsurgery and has to begin a long and tiring training to master techniques. We think that experimental surgery should play a role because it tests the validity and safety of new surgical techniques and allows special pathophysiological aspects to be studied. Furthermore experimental surgery could represent an essential stage in the training of young surgeons. We should find a balance between observance of the law and respect of the animals and, on the other hand, the role of experimental surgery because we should not forget that its most important aim is the improvement of the health of the humankind.

Feasibility of a porto-intracaval shunt for liver total vascular exclusion in the rabbit: preliminary report.

The animals do not tolerate prolonged caval and/or portal clamping which induces negative pathophysiological events such as release of kinins, damage of the intestinal mucosa, and bacterial translocation. In human liver surgery, these problems have been solved by bio-pump for veno-venous bypass. In order to find a simple method to reproduce a veno-venous bypass, we developed the porto-intracaval shunt and used it in six adult rabbits. The shunt tested was a self constructed 7-french polyurethane shunt modeled as an inverted Y. The inferior vena cava vein below the diaphragm and below the liver and the portal vein were gently dissected. The two longer branches of the shunt were inserted in the cava vein, while the remaining branch of the Y shunt was inserted in the portal vein. After clamping the hepatic artery, the liver was partially resected in three animals and after 60 min the shunt was removed. The insertion of the shunt was always easy and the animals tolerated well the procedure and the anhepatic phase. Our study has been performed in order to test especially the technical feasibility of this shunt in an effort to reduce portal and caval stasis during the anhepatic phase of the surgical procedures that require caval and portal clamping. The technical feasibility has been obtained but we believe that the materials and dimensions of the shunt have to be perfected and adapted depending on the size of the cava and portal veins.

Usefulness of microsurgery in the training of the general surgeon.

It is a common opinion that general surgery is the first step for whoever approaches a surgical discipline, and that whoever practices training in general surgery should learn the rudiments of each surgical branch. The role of microsurgery in the training of the general surgeon has not been well-established. Clinical applications of microsurgery in general surgery are few and are rarely required, and have been connected strictly to restricted indications. However, we think that microsurgery could be very useful to the general surgeon because it allows the execution of experimental research on rats, the only possibility permitted by law. In these studies the microsurgeon can perform many times and in a short time the same surgical operation, thus improving his skill, and easily getting familiarity with surgical instruments and sutures.

Microsurgery and varicocele: state of the art.

Many surgical procedures have been proposed in the treatment of varicocele; however, the rate of recurrence and of postoperative complications, together with important correlation of this disease with male sterility, has played an important role in determining the success of microsurgery. In the present brief review, the indications for microsurgery and microsurgical dissection and/or anastomosis are described in comparison to traditional surgery.

[Therapeutic strategy in thymomas]. / Strategia terapeutica nei timomi.

Between July 1989 to February 1994 eight patients with thymoma were operated in the First surgical Clinic of University of Catania; in seven the neoplasia was associated with myasthenia gravis, the severity of which was evaluated according to the Osserman's classification. The surgical treatment has been: total thymectomy in four patients, in two total and partial resection was carried out respectively, and in two a macrobiopsy was performed. The postoperative staging was carried out according to Masaoka. The neoadjuvant chemotherapy and postoperative radiation therapy have been analyzed. The authors concluded that a rigorous anatomo-surgical and histopathological classification is the best way for the right use of postoperative adjuvant therapies to reduce the incidence of local and distant recurrence of these tumors.

[Incidentalomas of the adrenal gland]. / Gli incidentalomi del surrene.

The wider application of radiological examinations (ultrasound, computed tomography) has led to the pre-clinical discovery of "masses" in some organs, especially in adrenal gland. As these tumors are incidentally discovered, they are called "incidentalomas", and this term has been universally accepted. As soon as adrenal incidentaloma has been diagnosed it is important to establish if the patient has to undergo immediate surgical exploration or it is possible to follow the patient radiologically. Hormonally active adrenal metastatic tumors and adrenal incidentalomas greater than cm 5 should be surgically treated, while other adrenal tumors can be followed radiologically. Median anterior laparotomy or bilateral subcostal incision give a good surgical view. It is important the cooperation with endocrinologist, cardiologist and anaesthetist in order to control possible hypertensive rises during surgical operation.

Calibration of papillotomy in the surgical treatment of papillary stenosis: the "little train".

Although laparoscopic and endoscopic surgery have brought about an indisputable revolution in biliary surgery, many surgeons still prefer open surgery for lithiasis of the common bile duct, and if it is associated with a papillary pathology, they perform a papillotomy. However, great controversy regarding the site, modalities, and extension of the papillary section has now developed among surgeons. Our technique is not original; however, we do propose a "calibration" of the papillotomy, carried out by constructing a "little train" made up of several consecutive Nélatons of increasing caliber to identify the sphincter fibers and to obtain sections proportionate to the size of the bile duct. Of the 115 patients in this series who were treated by open papillotomy, only 1 developed acute pancreatitis; 2 demonstrated bleeding, 1 of whom required surgical exploration.

[Multilocular cysts of the kidney in the adult]. / "Cisti multiloculare" del rene nell'adulto.

Liver transplantation in patients with Budd-Chiari syndrome.

Patients with Budd-Chiari syndrome (obstruction of the hepatic veins) and associated hepatic insufficiency may be candidates for orthotopic liver transplantation (OLT). In our series of 405 OLT patients, 3 were transplanted due to Budd-Chiari syndrome (0.7%). The indication for liver transplantation in these patients was severe hepatic insufficiency (chronic in two and acute in the third one). Morphologic study of the obstructions revealed apparently different causes, including thrombi, membranous webs in hepatic veins, and hydatid cyst compression. The surgical technique employed in these transplantations was similar to that for other etiologies. Due to its implications for the future course of OLT, it is important to determine the exact etiology of Budd-Chiari syndrome in the pretransplant period and to treat the patients with early and long-term anticoagulant therapy to avoid syndrome recurrence.

Misplacement of a jugular line in a facial vein.

We report an exceptional misplacement of a central venous catheter, from the right jugular vein where it was introduced, into the right thyro-lingual-facial trunk. A brief description of the clinical course and a literature review on catheter misplacement is presented. This case illustrates the importance of routine use of a chest X-ray, and when necessary contrast medium, to verify the correct location of the catheter tip.

[The diagnostic significance of the small bowel enema in lesions of the small intestine requiring surgery]. / Importanza diagnostica del clisma del tenue nelle lesioni di interesse chirurgico del piccolo intestino.

Given its anatomical location the small intestine is the section of the digestive tract most inaccessible to objective clinical and instrumental examination. For this reason, traditional investigation methods provide inadequate data. In the barium meal X-ray, images are superimposed and the barium excessively fragmented due to the tortuosity and length of the intestinal loop. Access problems limit the value of endoscopy. The indications to angiography are fairly restrictive. Ultrasound and CT scans provide no conclusive evidence in this area. The so-called Small Bowel Enema technique based on the direct infusion of an opaque contrast medium after duodenal intubation remains the only way to obtain images with a satisfactory diagnostic value and should be the method of choice in examinations of the small intestine. Introduced in the twenties, the value of the technique was long questioned, mainly because it was difficult to perform correctly and it is only quite recently that several decisive technological innovations have made it highly reliable. The present paper describes its use on a series of patients with suspected pathologies of the small intestine requiring surgical treatment. The aim is to specify the correct indications to this technique as well as its limitations with a view to promoting its appropriate use in routine practice. MATERIALS AND METHODS. The study covers 42 small bowel enemas performed on 29 male and 13 female patients aged 12-85 years. Indications to the enema included chronic abdominal pain in 28.5%, chronic diarrhea in 21.4%, pain+diarrhea in 14%, subocclusion in 16.5%, faecal blood in 11.9%, abdominal pain+diarrhea+intestinal haemorrhage in 4.7%, anaemia in 2.4%. We adopted the Sellink technique involving intubation with a French 14 Bilbao-Dotter probe and the infusion of 200-350 cc barium sulphate in a 90%-70% P/V concentration at a speed of 100 ml/min, followed by the infusion of 1000-1500 cc 0.5-1% methylcellulose in a 50-50 mixture with water for double contrast purposes. Mean duration of procedure 35-40 mins. RESULTS. We found lesions of the small intestine in 18 cases or 45% (true positives) and no alterations in 18 or 42.8% (true negatives). In 3 cases (7%) the examination was inconclusive. One false positive and one false negative complete the series, making a diagnostic accuracy of 89.1%. In 23.8% of the total series the diagnosis of Crohn's disease was confirmed; cancerous lesions were found in 11.9% and adhesions following earlier surgery in 9.7%. Surgery confirmed this diagnosis in 10 cases (5 tumours, 3 stenoses caused by adhesion fragments, 2 Crohn's disease) and disproved it in one case. Biopsy was used, for objective confirmation in 5 cases (2 Crohn's disease, 3 negatives). In the other cases reliance was placed on clinical course and the patients' response to treatment. DISCUSSION AND CONCLUSIONS. Examination of our results reveals that in most clinical cases the small bowel enema was used to confirm suspected Crohn's disease (31 cases out of 42) and with a very high degree of diagnostic accuracy (96.7%). In line with data in the literature we decided to base the indication to this examination on certain primary symptoms such as chronic abdominal pain, diarrhea, blood in the faeces, whether in isolation or in combination. On this rather general basis the diagnosis of Crohn's disease concerned only 23.8% of the cases studied, an incidence that rose dramatically in the few cases in which the indications were made more specific. We therefore conclude that the adoption of more restrictive criteria will improve the cost-benefit ratio for this test. Another major pathology in which small bowel enema possesses a high diagnostic value is partial obstruction of the small intestine.(ABSTRACT TRUNCATED AT 400 WORDS)

[The indications and results in 313 liver transplants]. / Indicazioni e risultati in 313 trapianti di fegato.

The authors report their experience on 313 liver transplantations performed in 255 patients. In 51.7% the indication to liver transplant was the cirrhosis, post alcoholic in 39.5% and post-hepatitis in 24.1%. The global mortality was 34.9% (89/255) with an actuarial survival of 53% at 74 months. We registered 10 cases (3.2%) of arterial thrombosis and 5 cases (1.6%) complications of portal anastomosis.

[Morphologic and endocrine changes in the male reproductive system after porta-caval anastomosis in rats. Experimental research]. / Alterazioni morfologiche ed endocrine dell'apparato riproduttivo maschile dopo anastomosi porta-cava nel ratto. Ricerche sperimentali.

Quantitative alterations of the sexual hormones are present in cirrhotic patients whose testicular volumes are decreased with tubular atrophy in more than 50% of cases. The authors performed an experimental study utilizing end-to-side portacaval anastomosis in the rat in order to evaluate the consequences of the complete interruption of the portal blood to the liver in the male genital system, i.e. testicular alterations, due to the missing hepatic inactivation. Forty male Sprague-Dawley rats were used for this study. Twenty rats were subjected to end-to-side porta-caval anastomosis according to Lee, 10 rats underwent sham-operation while the remaining 10 rats were utilized as negative controls. The rats were weighed and necropsied three and six months after surgery and the liver and genital organs were weighed. In rats subjected to porta-caval anastomosis loss of weight was shown, about 20 g three months after surgery and 30 g six months after surgery, while other rats (sham-operated and negative controls) showed an increase of its weight, about 60 g after three months and 80 g after six months. In rats subjected to porta-caval anastomosis the liver was hypotrophic and its weight was decreased in comparison with the control group. In the same rats testicular volumes were decreased and hypotrophic in comparison with the control groups with average length 0.5 to 1 cm, while control groups showed values of 1.7 to 2.5 cm. Testosterone levels were 0.50 ng/ml in rats subjected to porta-caval anastomosis while in control groups the levels were 2.20 ng/ml.(ABSTRACT TRUNCATED AT 250 WORDS)

[Incidence and surgical treatment of extrahepatic abdominal hydatidosis]. / Incidencia y tratamiento quirúrgico de la hidatidosis abdominal extrahepática.

From 1974 to May 1991, 417 patients with abdominal hydatid cyst disease were surgically treated. Twenty-eight patients had extrahepatic abdominal cyst disease (6.7%). Six patients had only extrahepatic disease where as 22 had associated hepatic and extrahepatic cysts. Most frequent sites were the peritoneum (52.7%), the spleen (22%) and pelvis (11%). Fourteen out of the 14 CT scans performed, detected the extrahepatic cysts. The preferred surgical technique was total closed cystectomy (in hepatic and extrahepatic cysts). Resection of the organ affected (8 splenectomies, 1 nephrectomy, 1 partial vertebral resection, 1 orchiectomy and 1 salpingo-oophorectomy) was also performed. There was no mortality and morbidity was 32.1%: 3 intraabdominal abscesses, 1 intraabdominal haemorrhage, 4 biliary fistulae and 1 partial necrosis of the large bowel. Only 3 patients (neither were treated with mebendazole) were reoperated on for recurrent peritoneal hydatic cyst.

[Splenic abscess]. / Absceso esplénico.

Splenic abscess is rare and may be present either as a localized area in the spleen or as part of a generalized sepsis. A 35 year old man presented with a two month history of anorexia, weight loss, fever, abdominal pain and arthralgia. Multiple abscesses localized in the spleen were diagnosed by CT and splenectomy was performed.
