RESUMO

Mondor's disease is a rare benign and self-limiting condition characterized by thrombophlebitis of the superficial veins of the anterolateral thoracoabdominal wall. We describe a case of Mondor's disease of the breast as a complication of an ultrasound-guided core needle biospy. The patient presented with a palpable cord-like structure in her left breast, associated with severe pain and tenderness. She was treated concervatively and complete resolution was observed after four weeks. We conclude that emergency clinicians and interventional breast radiologists should be aware of Mondor's disease as a potential complication of ultrasound-guided core needle biopsy of the breast.

RESUMO

Solitary cecal diverticulitis is a rare cause of abdominal pain in Western countries. The preoperative diagnosis is very difficult to establish and most patients are operated on with a presumptive diagnosis of acute appendicitis based on clinical grounds. We describe a very rare case of perforated posterior cecal diverticulum and discuss the challenges in establishing a correct preoperative diagnosis. We conclude that although very rare, the possibility of perforated posteriorcecal diverticulum should always be considered in the differential diagnosis of patients presenting with atypical clinical manifestations of acute appendicitis. A perforation of a posterior cecal diverticulum maybe associated with a mild clinical course without signs of peritonitis. Athorough preoperative evaluation including a computed tomography scan is essential in order to establish a correct preoperative diagnosis which is of utmost importance for treatment planning in the emergency setting. Simple diverticulectomy is an effective surgical treatment in the absence of extensive inflammatory changes and when a colonic tumor can be ruled out.

RESUMO

Despite the multi-systemic effects of influenza A/H1N1 virus, the occurrence of hepatic injury during the natural course of the infection remains a matter of debate. We performed a review of the published clinical studies which assess the above mentioned relationship, reviewing the studies published in PubMed database (English literature), using the key words "H1N1", "influenza A" and "liver". We excluded case reports and clinical studies that referred to pediatric and transplanted patients, pregnants and patients with known history of chronic liver diseases. From a total of 96 results, a total of 78 papers met one or more of the exclusion criteria set. Evaluating the remaining 18 published papers, 14 more were excluded as they did not provide any sufficient data, relevant to the subject of our review. Although the analysis of the remaining studies revealed the existence of conflicting results concerning the exact degree and the potential mechanisms of liver injury in H1N1 positive patients, it can be assumed that influenza A/H1N1 virus is -or at least could be- a hepatotropic virus.

RESUMO

BACKGROUND: Postoperative nausea and vomiting (PONV) are frequently encountered after thyroidectomy. For PONV prevention, selective serotonin 5-hydroxytryptamine type 3 (5-HT3) receptor antagonists are considered one of the first-line therapy. We report on the efficiency of granisetron and tropisetron, with that of placebo on the prevention of PONV in patients undergoing total thyroidectomy. METHODS: One hundred twenty-seven patients were divided into three groups and randomized to receive intravenously, prior to induction of anesthesia, tropisetron 5 mg, or granisetron 3 mg, or normal saline. All patients received additionally 0.625 mg droperidol. All episodes of postoperative PONV during the first 24 h after surgery were evaluated. RESULTS: Nausea visual analogue scale (VAS) score was lower in tropisetron and granisetron groups than the control group at all measurements (P<0.01) except for the 8-h measurement for tropisetron (P=0.075). Moreover, granisetron performed better than tropisetron (P<0.011 at 4 h and P<0.01 at all other points of time) apart from the 2-h measurement. Vomiting occurred in 22.2%, 27.5%, and 37.5% in granisetron, tropisetron, and control groups, respectively (P=0.43). CONCLUSIONS: The combination of the 5-HT3 antagonists with droperidol given before induction of anesthesia is well tolerated and superior to droperidol alone in preventing nausea but not vomiting after total thyroidectomy.

RESUMO

BACKGROUND: Preoperatively elevated neutrophil/lymphocyte ratio (NLR) is a negative prognostic factor of survival in various types of cancers. A retrospective study was conducted to examine if preoperative elevation of NLR is associated with higher risk for incidental papillary thyroid microcarcinoma (PTMC). METHODS: The study sample consisted of 26 patients with benign goiters, 31 patients with incidental PTMC, 26 patients preoperatively diagnosed with thyroid cancer, and 26 healthy controls. NLRs were compared regarding thyroidal pathology. RESULTS: The mean preoperative NLR was significantly elevated in patients with PTMC and thyroid cancer. In addition, the third and fourth quartiles of NLR included only patients with either PTMC or thyroid cancer. No significant differences in NLR occurred between patients with multifocal and unifocal PTMC. CONCLUSIONS: NLRs were significantly elevated in patients with incidental PTMC and thyroid cancer. The findings of this pilot study indicate that NLR should be considered an easily accessible biomarker for detecting incidental PTCM; nevertheless, further studies are required to confirm these preliminary results.

RESUMO

Intestinal pseudo-obstruction is considered to be one of the most frequent gastrointestinal manifestations of myasthenia gravis, accompanied by the presence of neoplasia of the thymus gland in the vast majority of the cases presented in the international literature. Despite the fact that myasthenia gravis has been implicated to be the cause of recurrent episodes of intestinal pseudo-obstruction, adhesive ileus has never been reported to complicate this - in any sense rare - condition. We present a unique case of a patient with myasthenia gravis, free of thymus neoplasia, who was submitted to emergency surgery due to the presence of extended adhesive ileus as a complication of chronic intestinal functional obstruction.

RESUMO

BACKGROUND: Ghrelin is an appetite hormone that influences the gastrointestinal function and regulates energy metabolism. Growing evidence also suggests that this hormone plays a central role in immune modulation. Each surgical operation is followed by a series of inflammatory and metabolic changes that constitute the stress response. The aim of our study is to evaluate the effect of stress during different types of abdominal surgery in ghrelin serum levels. METHODS: An overall of 25 patients were prospectively allocated in two groups based on the type of surgical operation. Group A (n = 10) patients were scheduled to undergo cholecystectomy, whereas Group B (n = 15) patients underwent colectomy. Serum ghrelin concentrations were evaluated in each patient preoperatively, after the induction of general anesthesia and tracheal intubation, one and five hours after the beginning of surgery and the morning of the first and second postoperative day. RESULTS: In both groups serum ghrelin concentrations reached their peak level at 24 hr (Group A: 8.4 ± 3.4 ng/mL; Group B: 7.4 ± 1.8 ng/mL) and these values were significantly higher than those in the preoperative period (Group A: 5.0 ±1.5 ng/mL; Group B: 4.8 ± 0.6 ng/mL) (P < 0.05). Forty eight hours after surgery the levels of ghrelin returned to their preoperative status. Patients' gender, age, ASA score and type of surgical procedure did not influence the serum ghrelin levels. CONCLUSIONS: Serum ghrelin concentration appears to elevate in response to surgical stress. Future studies are needed to improve comprehension of the mechanisms underlying responses of this hormone to acute surgical stress and to evaluate their possible clinical implications.

RESUMO

BACKGROUND: Gastrin has been shown to exert carcinogenic effect to the epithelium of the colon. This study examines whether hypergastrinemia and H. pylori infection -especially infection by the CagA+ strain- are statistically associated with colorectal cancer and examine possible correlations with the colorectal cancer stage and lymph node metastasis. METHODS: In this prospective case-control study, fasting serum samples from 93 consecutive patients with colorectal cancer treated in a university surgical clinic were preoperatively collected and serum levels of gastrin were measured. A group of 20 age matched hernia patients were used as controls. The pathology report of the specimens was documented and statistical analysis of the data where performed with the spss 17 statistical suite. RESULTS: H. pylori IgG antibodies was reported in 66/93 (71%) in the colorectal cancer group and 13/20 patients in the control group (65%), the difference having non-statistical significance (P = n.s). The prevalence of cagA protein expression in the anti- H. pylori IgG+ patients were higher in the colorectal cancer group (56% positivity), when compared to the control group (38,4% positivity) but the difference was not of statistical significance (P = n.s). The mean levels of serum gastrin levels in the two groups did not significantly differ (Ca group 51.1 ± 36.6 pg/mL vs Control 49.8 ± 17.6 P = n.s.). Patients with lymph node metastasis had higher serum gastrin levels than patients without metastasis and this difference was statistically significant. (53.6 vs 41.06 pg/mL P = 0.025). CONCLUSIONS: Although the serum gastrin levels were not statistically different between the TNM stages of our patient cohort, our data found that serum gastrin levels were significantly higher in patients with lymph node metastasis. Whether gastrin is implicated in the ability of cancer cells to metastasize to the lymph nodes merits further research.

RESUMO

INTRODUCTION: Adrenocortical oncocytomas are extremely rare tumors, considered to be non-functional and of low malignant potential. Despite the great advance in laparoscopic techniques, there are extremely limited reports of laparoscopic approach of adrenocortical oncocytomas. Herein is presented a challenging case of laparoscopic approach to a large adrenocortical oncocytoma, underlining the safety and feasibility of laparoscopy in the surgical management of these extremely rare adrenal tumors. PRESENTATION OF CASE: A 34 year-old male was referred for surgical evaluation after the incidental discovery of a large right adrenal mass, during ultrasound examination due to renal colic. Further imaging evaluation revealed a well circumscribed capsule around the mass was demonstrated, with no evidence of infiltration of the neoplasm to periadrenal tissues. The patient was scheduled for laparoscopic right adrenalectomy, running an uneventful postoperative period. Histopathology revealed the presence of an adrenal oncocytoma. DISCUSSION: Recent studies have demonstrated that approximately one third of adrenocortical oncocytomas are associated with hormonal hypersecretion, as well as that one fifth of them demonstrate malignant biological behavior. From this point of view, there is emerging evidence in favor of the necessity of surgical excision as the treatment of choice. In spite of the progress of laparoscopic surgery, only three cases of laparoscopic excision of these tumors have been reported up to date. CONCLUSION: Laparoscopic surgery offers a safe alternative in confronting adrenocortical neoplasms, even when the biological behavior of the tumors cannot be pre-operatively evaluated in a definite way.

RESUMO

Esophageal sclerosis is the most common visceral manifestation of systemic sclerosis, resulting in impaired esophageal clearance and retention of ingested food; in addition, co-existence of lung fibrosis with esophageal scleroderma is not uncommon. Both the progression of generalized connective tissue disorders and the damaging effect of chronic aspiration due to esophageal dysmotility appear to be involved in this procedure of interstitial fibrosis. Nifedipine is a widely prescribed calcium antagonist in a significant percentage of rheumatologic patients suffering from Raynaud syndrome, in order to inhibit peripheral vasospasm. Nevertheless, blocking calcium channels has proven to contribute to exacerbation of gastroesophageal reflux, which consequently can lead to chronic aspiration. We describe the case of severe exacerbation of interstitial lung disease in a 76-year-old female with esophageal sclerosis who was treated with oral nifedipine for Raynaud syndrome.

RESUMO

UNLABELLED: Tubular adenomas, also known as pure adenomas, are rare epithelial tumors of the breast. Only a few cases have been reported in the literature, especially in young women of reproductive age. Postmenopausal women are very rarely affected. We describe here a very rare case of tubular breast adenoma in a postmenopausal woman who presented with a gradually enlarging breast lump. Clinical examination and imaging studies revealed a non-tender well circumscribed left breast tumor suggestive of a fibroadenoma. Due to the history of progressive enlargement of the breast lump, a surgical excision was performed. Histological findings were suggestive of a tubular breast adenoma. We conclude that although tubular breast adenoma is rare, it should always be considered in the differential diagnosis in postmenopausal patients presenting with a gradually enlarging breast mass. Preoperative diagnosis is difficult because tubular adenoma is indistinguishable from a fibroadenoma on physical examination and breast imaging. Surgical excision is necessary to establish a definitive diagnosis. Clinical presentation and management of our patient are discussed along with a review of the literature. KEYWORDS: Tubular adenoma; Breast; Breast mass.

RESUMO

Background. The objective of our study is to investigate the potential effect of adjusting preoperative platelet to lymphocyte ratio, an emerging biomarker of survival in cancer patients, for the fraction of large platelets. Methods. A total of 79 patients with breast neoplasias, 44 with fibroadenomas, and 35 with invasive ductal carcinoma were included in the study. Both conventional platelet to lymphocyte ratio (PLR) and the adjusted marker, large platelet to lymphocyte ratio (LPLR), were correlated with laboratory and histopathological parameters of the study sample. Results. LPLR elevation was significantly correlated with the presence of malignancy, advanced tumor stage, metastatic spread in the axillary nodes and HER2/neu overexpression, while PLR was only correlated with the number of infiltrated lymph nodes. Conclusions. This is the first study evaluating the effect of adjustment for large platelet count on improving PLR accuracy, when correlated with the basic independent markers of survival in a sample of breast cancer patients. Further studies are needed in order to assess the possibility of applying our adjustment as standard in terms of predicting survival rates in cancer.

RESUMO

The increasing use of laparoscopic cholecystectomy has led to an increased frequency of gallbladder perforation and subsequent gallstone spillage in the abdominal cavity. Occasionally unretrieved gallstones can cause infection, adhesions, and obstruction. Furthermore, spilt stones can cause erosion into adjacent organs and can migrate to distant sites, causing a variety of complications. We report the unusual case of a patient who presented with spontaneous erosion of gallstones through Grynfeltt's triangle, 1 year after laparoscopic cholecystectomy and review the current literature.

RESUMO

INTRODUCTION: Adequate lymph node evaluation is an important determinant of prognosis in patients with colorectal cancer. Current guidelines recommend evaluation of at least 12 lymph nodes; however, a significant number of patients fail to meet these criteria. AIM: To investigate the factors that influence adequate recovery and evaluation of lymph nodes in colorectal cancer. METHODS: We retrospectively analyzed 454 consecutive cases of colorectal cancer surgically treated from September 2000 to September 2006. Univariate and multivariate linear and logistic regression analysis was used to study the effect of various factors in lymph node recovery. RESULTS: The number of lymph nodes retrieved ranged from 0 to 62 with a median of 13 nodes. Overall, 189 (41.6%) patients had fewer than 12 nodes removed. Patient age, tumor stage, location and size were associated with lymph node retrieval. Multivariable regression revealed that the aforementioned variables, including gender and hospital type, explained 17% of the observed variance of the lymph node number. CONCLUSION: Patient and tumor characteristics, although important, are only partly responsible for the variation of lymph node yield. Quality of surgical resection and/or the thoroughness of examination of the tissue by the pathologist might explain the wider proportion of this variance. Training in colorectal node evaluation could help to improve the quality of cancer care.

RESUMO

BACKGROUND: Despite their safety and effectiveness in thyroid surgery, the previous harmonic scalpel instruments are considered large and cumbersome by several surgeons. An innovative technical improvement of the device has been made available since 2008. The objective of this study was to compare the results of total thyroidectomy using the new harmonic scalpel (FOCUS) with that with the previously available device (HARMONIC ACE). METHODS: A prospective randomized study of all total thyroidectomies between February and July 2008 was conducted. Patients (n = 90) were randomized to undergo total thyroidectomy with FOCUS (group A, n = 45) or HARMONIC ACE (group B, n = 45). RESULTS: No significant differences were identified between the 2 groups in terms of demographics, reoperative thyroid surgery, thyroid gland weight and diameter, pathologic diagnosis, preoperative and postoperative serum PTH and calcium levels, postoperative complications, duration of hospital stay, and final outcome. The mean operative time was less in group A than group B (63 ± 7 min vs 76 ± 8 min, P = .009). CONCLUSION: The new harmonic scalpel is a useful adjunct to the armamentarium of the thyroid surgeon. It is safe, effective, and hand friendly, offering great capabilities for delicate tissue grasping and dissection. Use of this device decreased operative time compared with the previously available instrument.

RESUMO

A 78-year-old euthyroid patient presented for evaluation of a symptomatic, slowly growing neck mass. Ultrasound scan revealed a multinodular goiter and a hypoechoic nodule of the right thyroid lobe. Total thyroidectomy was performed and the lesion was completely excised. Definite diagnosis was obtained after histological examination of the surgical specimen. Cavernous hemangiomas of the thyroid gland are infrequent lesions which may escape diagnosis preoperatively. An effort should be made not to rupture these lesions in order to ensure a bloodless procedure.
