Clinical-Morphological Aspects in Spinal Tuberculosis.

Osteoarticular tuberculosis (OATB) Aim: The authors made a clinical morphological assessment of tissue samples from patients admitted in Surgical Departments of the Emergency County Hospital of Craiova, Romania, between 1990 and 2015, proved as presenting tuberculous lesions of the spine in the Department of Pathology of the same Hospital. MATERIALS AND METHODS: The studied material consisted of bone, joint and sometimes muscle tissue fragments resulted from biopsies or surgical excisions from 7 cases coming out of 54 patients investigated in the above-mentioned period of time, where the established histological diagnosis was tuberculosis (TB). For diagnostic confirmation, Ziehl-Neelsen staining has been used as a rule but, in some cases, immunohistochemistry was also used. RESULTS: TB lesions have prevailed in men and around the age of 50 years. Thoracic segment of the spine was the most involved. Epithelioid and giant Langhans cells dominated the inflammatory cellular population. Necrosis was always present, usually in its classical acidophilic form. Fibrosis was almost always absent. On the whole, the granulomatous reaction was in almost half of the cases hyporeactive and disorganized. CONCLUSIONS: The clinical morphological profile of our series is fitting with data described in the literature. Because of its life threatening potential, spinal TB should be investigated thoroughly especially in its morphological features in order to obtain as quickly as possible an etiological diagnosis.

Anisotropy Influences on the Drug Delivery Mechanisms by Means of Joint Invariant Functions.

In the frame of Higuchi's type functionality, this paper presents the anisotropy influences on the drug delivery mechanisms through the joint invariant functions to the simultaneous actions of the two SL(2R) isomorphic groups. Then, a new equation for drug delivery mechanism, independent of the type of polymer matrix and/or drug, is proposed.

Appendicular Mucocele: Possibilities and Limits of Laparoscopy. Brief Series and Review of the Literature.

INTRODUCTION: Appendicular mucocele, a cystic dilatation of the appendix, is a rare disease, but unfortunately about 1/10 of cases evolves into pseudomyxoma peritonei. METHODS: We performed a prospective study between 1 January 2010 to 31 December 2014 in order to track the incidence, symptoms, and circumstances of diagnosis, treatment and evolution of these rare tumors. RESULTS: A total of seven patients underwent curative surgery for a mucocele of the appendix: one woman and six men with an average age of 59.71 years. Clinical signs, present in two cases, were uncharacteristic. Ultrasound performed in all cases, could guide diagnosis in 5 cases. CT performed in 5 cases diagnosed only two cases. All cases were operated on: the open approach was used in four cases and a minimally invasive in three cases. We performed two right colectomies, an open appendectomy associated to anterior resection of the rectum, two laparoscopic appendectomies and two appendectomies and cecum resection with stapler, one by open approach and one by a minimally invasive approach. Intraoperative spillage of mucinous tumor did not occur in any case. The mean hospital stay was 5.7 days. Postoperative complications were present in 1 case (14.2%): wound infection. The average follow-up period was 40.28 months. (Range 6 to 48 months). No tumor recurrence or readmission, such as pseudomyxoma peritonei, has occurred. CONCLUSIONS: Appendicular mucocele is a rare entity; it can be found incidentally and it can mimic acute appendicitis, appendicular plastron or cecum tumor. Once diagnosed, surgical treatment is required for fear of perforation, tumor evolution and the emergence of the rule of complications. Laparoscopic approach in selected cases can be used, accompanied by safety measures to avoid iatrogenic perforation and peritoneal and parietal seeding.

Emergency pancreaticoduodenectomy for bleeding pancreatic pseudoaneurysm in patient with common mesentery and replaced right hepatic artery.

Pancreaticoduodenectomy is infrequently performed in emergency, so much the less in lack of traumatic evidence.A rare vascular complication of the pancreatic pseudocyst,the pseudoaneurysm, presents as a pulsating malformation which may lead to life-threatening bleeding if left untreated.Its optimal treatment remains controversial. Most authors agree that angioembolization is the first step to stabilize the patient's condition, with further surgery if such be the case.We herein report an unusual case of pancreatic head pseudocyst complicated with a bleeding pseudoaneurysm arising from the inferior pancreaticoduodenal artery, in a patient with multiple comorbid conditions, common mesentery,hepatic artery variant and hemodynamic instability. An emergency early retropancreatic approach pancreaticoduodenectomy was performed with uneventful immediate and long-term outcome. We highlight that emergency surgery allowed both rapid control over the bleeding with hemostasis and removal of the pseudocyst. This is particularly relevant in high-risk patients in whom selective angioembolization is no more of choice.

Laparoscopic adrenalectomy for large solid cortical tumours--is it appropriate?

BACKGROUND: Laparoscopic adrenalectomy, the procedure of choice for small benign adrenal tumours, is also used for large tumours. Our study aims to assess the outcome of large adrenal tumours laparoscopically resected. METHODS: All patients with laparoscopic adrenalectomy performed in between 2002 and 2009, without preoperative or intraoperative malignant characteristics, were reviewed. Clinical, biochemical and CT follow-up data were reviewed for evidence of recurrent disease. RESULTS: Fifty patients underwent laparoscopic adrenalectomies in our unit, 18 of them having solid cortical tumours > or = 7 cm without preoperative or intraoperative malignant features: 6 Cushing's syndrome tumours, 8 non-secreting tumours, 4 aldosteronomas. The mean age of the patients was 46.89 years (range 22-64 years), and the mean tumour size 7.57 cm (range 7-9.1 cm). Histology identified 10 cortical adenomas, 4 malignant tumours, and 4 indeterminate tumours. The mean - follow-up was 28.94 months (range 4-58 months). Three patients died of systemic recurrent disease (liver and lung metastases) at 12, 19 and 21 month, respectively, after operation. One patient underwent a left hepatectomy for liver metastases, 33 months postoperatively. Fourteen patients have no evidence of recurrence. CONCLUSIONS: Adrenal tumours > or = 7 cm without pre- or intraoperative evidence of malignancy are resectable laparoscopically. This approach is unlikely to worsen the long-term outcome. The mortality is related to the malignancy.

Palliative gastrectomy in patients with stage IV gastric cancer--our recent experience.

BACKGROUND: Patients with metastatic gastric cancer are usually not good operative candidates. Recent improvements in surgical techniques allowed palliative gastric resection and other surgical procedures. METHOD: We have examined the place of palliative gastrectomy and its impact on survival in stage IV gastric cancer patients admitted in 2003-2008 period. RESULTS: From a total of 295 patients with gastric cancer, we found 140 patients with stage IV disease; 85 of them had no resection (45 received only chemotherapy) and 55 underwent palliative gastric resection with or without postoperative chemotherapy. Mean survival in non-operated patients with chemotherapy alone was 6.4 months, not significantly different to that of the patients with palliative surgery alone (8.9 months). The group with palliative surgery and adjuvant therapy had a significantly better mean survival (17.8 months). Mortality and morbidity rates associated with palliative surgery were 9% and 34.5%, respectively. CONCLUSIONS: These data suggest that palliative surgery associated with adjuvant chemotherapy can improve survival in patients with stage IV gastric cancer.
