A nephron-sparing surgical procedure for Fraley's syndrome. A case report.

A 14.5-year-old girl with Fraley's syndrome, which caused left flank pain and massive haematuria with anaemia underwent left renal surgery. The infundibulum for the left upper calyx group was entrapped between the lower segmental renal artery and one branch of the renal vein. Despite other known surgical procedures, the surgeon explored the area around the entrapped infundibulum and resected the vein. Impression of the infundibulum disappeared, the dilatation of the upper calyces diminished, the pain was immediately relieved, and the haematuria stopped. In the two-year follow-up period the patient remained healthy, without haematuria or a subjective feeling of illness. The surgical treatment performed was successful, and it is also one of the most nephron-sparing procedures available.

Frequency of portal and systemic bacteremia in acute appendicitis.

BACKGROUND: Acute appendicitis is the most common condition requiring an emergency abdominal operation in childhood. In the present study, we analyzed the frequency of portal and systemic bacteremia in 42 patients with acute appendicitis and determined the microbial agents responsible for an acute appendicitis and for portal and systemic bacteremia. METHODS: Appendectomies were performed on 50 young patients (5-18 years of age), as well as clinical and bacteriological tests. Six independent samples from each patient isolated from the peripheral vein, superior mesenteric vein, appendix and peritoneum were obtained prior to surgery, during surgery and after surgery for biochemical, immunologic and bacteriologic examination. RESULTS: Pathohistology confirmed the diagnosis of appendicitis in 42 patients, while in the other eight patients there were no obvious pathologic findings, so they served as a control group. Of 50 patients with a clinical appearance of acute appendicitis, in 19 patients (38%) we detected portal bacteremia in the mesenteric vein, while in only three cases (6%) did we find systemic bacteremia detected from the peripheral vein. Furthermore, bacteriologic analysis revealed that Bacteroides spp. and Escherichia coli were the predominant species isolated. CONCLUSIONS: The results presented in this paper suggests that portal bacteremia did not influence peripheral blood reactions. Furthermore, in the present study we have found a positive correlation between the smear and bacteremia of the superior mesenteric vein, but not with the bacteremia of systemic blood.

Laparoscopic and laparotomic cholecystectomy: a randomized trial comparing postoperative respiratory function.

BACKGROUND: The fact that pulmonary complications occur in 20-60% of the patients subjected to abdominal operations clearly indicates that the lungs are the most endangered organ during the postoperative period. OBJECTIVE: The aim of this study was to demonstrate the impact of cholecystectomy on postoperative respiratory disturbances by comparing the laparotomic cholecystectomy with laparoscopic gallbladder removal. PATIENTS AND METHODS: A hundred cholecystectomized patients were included in the prospective randomized clinical trial. Half of the patients were operated on by the laparotomic procedure, whereas the other half underwent laparoscopic cholecystectomy. Spirometric parameters, arterial blood gases, and acid-base balance were determined before the operation, and at 6, 24, 72 and 144 h postoperatively. Abdominal distension was assessed by auscultating intestinal peristaltics, abdominal circumference measurement, and time interval to restitution of defecation. RESULTS: Six hours postoperatively, the values of ventilation parameters decreased on average by 40-50% from the baseline preoperative values in both groups of patients. The group of patients submitted to laparotomic cholecystectomy had significantly lower spirometric values and slower recovery of the ventilation parameters than the laparoscopic cholecystectomy group. Abdominal circumference was significantly greater and the time needed for restitution of peristaltics and defecation was significantly longer in the laparotomic cholecystectomy group compared to the group of laparoscopic cholecystectomy. CONCLUSIONS: Statistically significant impairments including hypoxia, hypocapnia and hyperventilation were observed in the patients submitted to laparotomic cholecystectomy, indicating the presence of objective respiratory risk, especially in elderly patients and patients with obstructive pulmonary diseases or cardiac insufficiency.

Analysis of medical aid to Croatian Army soldiers wounded at the front line.

OBJECTIVE: Analysis of medical aid to Croatian Army soldiers at the front lines. METHODS: This investigation concerned 115 severely wounded Croatian soldiers (males, median age 29 years, range 17-57 years) at three rehabilitation institutions. All had been wounded at the front line by various explosive devices or bullets. In the investigation, semi-structured clinical interviews were used. RESULTS: First aid was provided to 47 soldiers (40.9%) within 15 minutes and to 44 soldiers (38.3%) within 1 hour. First aid was either self-administered or given by fellow combatants in 55 cases (47.8%), by physicians in 37 cases (23.2%), and by medical technicians and orderlies in 21 cases (18.2%). The basic procedures of medical aid were hemostasis, hemodynamic substitution, immobilization, and analgesia. First surgical operations were performed at health stations on 4 soldiers (3.5%), at war hospitals on 43 soldiers (37.4%), and at evacuation hospitals on 68 soldiers (59.1%). CONCLUSION: First aid either self-administered or provided by fellow combatants is the most important procedure at the front lines before medical aid is administered.

Psychological characteristics of wounded and disabled Croatian war veterans.

OBJECTIVE: Evaluation of the psychological state of a group of 119 Croatian disabled war veterans who suffered grave traumatic war experiences during the war in Croatia (1991-1992). METHODS: Semistructured Clinical Interview, Profile Index Emotions test, and Zung's Self-Rating Depression Scale were used to assess disabled war veterans accommodated in special institutions for rehabilitation. RESULTS: Changes in psychological functioning were established in 63.8% of disabled war veterans, the most frequent among them being indisposition, irritability, anxiety, and fear. In nearly half of the veterans there were changes in their relationships with close persons, difficulties in accepting the reality of their situations, and increased aggressiveness. Higher average values on the depression index (0.52) were also established. CONCLUSION: The established change in the psychological profile of disabled Croatian war veterans was lower than expected. However, because of their great vulnerability, it is necessary to increase efforts to secure their complete psychosocial recovery.

Congenital elevation of the scapula (Sprengel's deformity).

A case of Sprengel's deformity (congenital elevation of the scapula) in a 4-year-old boy, with a major cosmetic defect and compromised shoulder function, especially on abduction, is presented. The boy was operated on by Green's technique, with excellent cosmetic and functional result. Although Woorward's operative technique has generally been preferred in the treatment for Sprengel's deformity, the result obtained showed Green's procedure to be a satisfactory choice in this patient.

[Our initial experience with video-assisted thoracoscopic surgery (VATS)].

Diagnostic and therapeutic potentials and our first two-year experience with video-assisted thoracic surgery (VATS) are reported. From May 1995 to April 1997, at the Department of Surgery, University Hospital Split, VATS approach was planned in 55 cases (recurrent pneumothorax in 23, tension pneumothorax in 1, traumatic effusion in 5, malignant metastatic lung tumor in 1, benignant lung tumor in 11, traumatic effusion in 5, suspected mediastinal lymph nodes in 4, long lasting unconfirmed pleural effusion in 9, foreign body in 1, mediastanal cyst in 1). Of these, 48 procedures (87.2%) were performed using VATS (diagnostic thoracoscopy in 12, wedge resection with or without pleural abrasion in 21, partial pleurectomy in 1, decortications in 3, mediastinal lymph nodes biopsy in 4, lung biopsy in 7). Seven patients (12.7%) underwent conventional posterolateral thoracotomy. Complications included persistent air leak in three patients, prolonged bleeding in one patient and supraventricular tachycardia in one patient. The mean duration of chest tube drainage after the procedure was 3.7 days (range 2 to 19 days), and mean hospital stay was 5.1 days (range 3 to 15 days). All patients received routine antimicrobial chemoprophylaxis with single-dose ceftriaxone 2 g intravenously immediately prior to the surgery, and average postoperative patient-controlled analgesia with buprenorphine 0.15 mg. We conclude that VATS is a very useful alternative to conventional thoracotomy in managing cases of exploration, recurrent spontaneous pneumothorax, benign pulmonary lesions, solitary pulmonary nodes, early decortications and different intrathoracic biopsies.

Aldosterone and blood pressure in obese subjects during short-term starvation.

Changes in plasma renin activity (PRA) and aldosterone concentration during 10 days of starvation were studied, together with the relationship among PRA, aldosterone, plasma volume, sodium balance and mean blood pressure (MBP). Study subjects were 16 obese individuals (13 females and 3 males; age ranged 18-50 years) with a body mass index greater than 30 kg/m2. Total fasting induced a significant decrease in body weight, MBP, plasma volume and urinary sodium concentration, and a rise in PRA and aldosterone concentration. Before starvation, there was a significant correlation between aldosterone concentration and MBP. This data support the hypothesis that aldosterone is one of the factors which elevate blood pressure in obese subjects. Much of the initial fall in blood pressure during starvation seemed to be due to an imbalance between the cessation of sodium intake and excessive natriuresis.

Penetrating thoraco-abdominal war injuries.

BACKGROUND: From April 1991 till December 1995, Split University Hospital played a major role as a third échelon war hospital during the war in Croatia and Bosnia and Herzegovina. Among 2856 treated battle casualties in general, 70 patients with penetrating thoraco-abdominal war injuries were treated at the Department of Surgery. Explosive wounds were present in 38 (54%), gunshot wounds in 32 (45%) and puncture wounds in four (5.70%) patients. METHODS: The medical data from the evacuation unit, transportation, emergency department, surgical management and follow-up were obtained and analyzed. The principle of treatment of such patients is described, with particular reference to thoracophrenolaparotomy as the most efficient diagnostic-therapeutic surgical approach. RESULTS: There were considerably more explosive wounds than gunshot and puncture wounds (ratio 38/32/4). Resource utilization analysis showed a great amount of blood products (average 1.250 ml per patient), rehydrant solutions (average 3.750 ml per patient) and seven days antimicrobial chemoprophylaxis (penicillin, gentamycin, metronidazole) used. Mean time elapsed between injury and definitive surgical repair was seven hours (range, 1 to 48 hours). Recovery on discharge was recorded in 61 (80%) and lethal outcome in nine (13%) patients. CONCLUSIONS: The treatment of respiratory insufficiency and hemorrhagic shock, and prevention of infection are the basis of the management of these injuries. Treatment success depends on emergency first-aid, quick transportation, early diagnosis, resuscitation, surgical therapy and intensive care.

[Occurrence of thromboembolic complications in patients with dilated cardiomyopathy. Retrospective-prospective study].

The purpose of the present study was to determine the prevalence of thromboembolic events in patients with primary and secondary (ischemic) dilated cardiomyopathy (DC), with regard to basic rhythm, sinus or atrial fibrillation. Retrospectively, over three years, from January 1, 1989 to December 31, 1991, the case histories of 75 inpatients with DC, mean age 56.2 +/- 14.1 years, 41 in sinus rhythm and 34 in atrial fibrillation from Clinic Hospital Split were analyzed and compared to those of 75 controls (heart failure with no DC). The incidence of thrombi, embolisms and mortality in both subgroups was similar, while the prevalence of thromboembolic events was significantly higher in the analyzed than in the control group (decompensated patients with ischemic cardiomyopathy and without cardiomegaly) (9/75:1/75, p < 0.05). Prospectively, between 9 and 22 months, from December 1, 1991 to September 30, 1993 51 consecutive decompensated outpatients with DC, in NYHA class II and III, mean age 54.2 +/- 15 years, were followed-up. Bilirubin, lactic dehydrogenase, prothrombin time and activated partial thromboplastin time were determined. 1-D and 2-D transthoracic echocardiographic exam was performed and clinical status was assessed. There were 24 patients in sinus rhythm and 27 patients in atrial fibrillation. The prevalence of thromboembolic events, thrombi and mortality in both subgroups was similar. The laboratory findings, indicators of possible thrombogenesis or thrombolysis, did not show any significant difference in both subgroups. The incidence of thrombi in both parts of this study was low, amounted to only 9.5% (12/126) with no clear signs of thromboembolism (these patients were anticoagulated!). Altogether 12.6% (16/126) patients suffered thromboembolic events, 9 in retrospective and 7 in prospective part of the trial (more patients were anticoagulated in prospective then in retrospective study, 5 versus 19; p < 0.05). We conclude that thromboembolism in patients with decompensated DC are rare, but appear at significantly higher rate than in decompensated patients with ischemic cardiomyopathy and no cardiomegaly. The beneficial effects of anticoagulant therapy are to be expected in these patients regardless of the basal rhythm. This hypothesis must, however, be assessed in a prospective, multicentric trial.
