What to Do, and What Not to Do, When Diagnosing and Treating Breakthrough Cancer Pain (BTcP): Expert Opinion.

Clinical management of breakthrough cancer pain (BTcP) is still not satisfactory despite the availability of effective pharmacological agents. This is in part linked to the lack of clarity regarding certain essential aspects of BTcP, including terminology, definition, epidemiology and assessment. Other barriers to effective management include a widespread prejudice among doctors and patients concerning the use of opioids, and inadequate assessment of pain severity, resulting in the prescription of ineffective drugs or doses. This review presents an overview of the appropriate and inappropriate actions to take in the diagnosis and treatment of BTcP, as determined by a panel of experts in the field. The ultimate aim is to provide a practical contribution to the unresolved issues in the management of BTcP. Five 'things to do' and five 'things not to do' in the diagnosis and treatment of BTcP are proposed, and evidence supporting said recommendations are described. It is the duty of all healthcare workers involved in managing cancer patients to be mindful of the possibility of BTcP occurrence and not to underestimate its severity. It is vital that all the necessary steps are carried out to establish an accurate and timely diagnosis, principally by establishing effective communication with the patient, the main information source. It is crucial that BTcP is treated with an effective pharmacological regimen and drug(s), dose and administration route prescribed are designed to suit the particular type of pain and importantly the individual needs of the patient.

Polyp of the cecum. Laparoscopic-assisted polypectomy.

The Authors discuss on a laparoscopic-assisted approach for excision of a sessile villous adenomatous polyp of the cecum, unresectable by endoscopy. Because of the large implant of the polyp, endoscopic polypectomy was considered at high risk and a surgical laparoscopic procedure was scheduled for removal of the lesion. After right colon mobilization, an intraoperative endoscopy confirmed the location of th polyp in the posterior wall of the cecum, closed to the ileo-cecal valve. A small 10 cm laparotomy, through which the cecum was pulled out the abdominal cavity, was performed. Then, a minimal colotomy along the intestinal taenia was carried out to allow a safe and complete excision of the polyp. This laparoscopic approach differs from the other laparoscopic-assisted methods reported in the Literature since it provides at the same time the postoperative advantages associated with minimal access surgery and a safe oncological removal of the polyp with low risks of complications.

Laparoscopic treatment of mucinous adenocarcinoma of jejunum associated with celiac disease. Case report.

Mucinous adenocarcinoma of the small bowel is very rare, and only few cases have been described in the literature. Association of this tumor with celiac disease has never been published. The authors report a unique case of jejunal mucinous adenocarcinoma in which a concomitant celiac disease has been histologically recognized. The difficult diagnosis, the role of laparoscopic surgery and the relationship between small bowel tumors and celiac disease are discussed. A 49-year-old man presented with recurrent melena, nausea, vomiting and anemia. A stenosis of the jejunum was documented by means of CT scan and video capsule enteroscopy. A laparoscopy was scheduled. A tumor, found in the first jejunal loop, was removed by laparoscopic surgery. Histopathology revealed a rare mucinous adenocarcinoma associated with epithelial changes secondary to celiac disease. Although small bowel tumors are rare entity, in patients with celiac disease complaining of symptoms related to altered intestinal transit or occult bleeding, an appropriate work-up should be planned for diagnosis. Mucinous type intestinal adenocarcinoma, even if never published before, could be observed. Laparoscopic surgery is often essential for the diagnosis and treatment.

[Venous thromboembolism prophylaxis after general surgery: where are we now?]. / Profilassi antitrombotica nel paziente chirurgico: a che punto siamo?

Venous thromboembolism (VTE) is a frequent complication in patients undergoing major surgery, with the possibility of long-term disability or fatal outcome. The rationale of the thromboprophylaxis in all patients can be summarized in three points: 1) the VTE is common in some types of surgery; 2) the VTE can be fatal; 3) thromboprophylaxis is highly effective and safe and, besides these clinical benefits, leads to lower total costs of treatment without further diagnostic and a new shelter for treating venous thrombosis. The surgical patients may present at admission one or more risk factors for VTE, The effect of this risk is cumulative, it is important to stratify the risk and to established an adequate prophylactic strategy. Today there is a unanimous consensus that the low molecular weight heparins are both effective and safe in preventing VTE in surgical patients. Unanimously approved guidelines can help surgeons in making decisions regarding VTE prophylaxis.

Laparoscopic left colectomy: from the perfect knowledge of surgical anatomy to the proper surgical technique.

Laparoscopic colo-rectal surgery has been increasingly accepted and performed in several surgical centres. However, there are still concerns about the intra-operative risks and therefore on the safety of the procedure especially during the learning curve. As a matter of fact, in approximately one third of laparoscopic colo-rectal procedures, an intra-operative complication, mainly bleeding or iatrogenic injuries, may occur. In this paper, according to our experience, we analyse step by step the surgical technique of the laparoscopic left colectomy and evaluate the technical difficulties and complications in order to avoid them.

[Laparoscopic treatment of adrenal myelolipoma: case report and review of the literature]. / Trattamento laparoscopico del mielolipoma surrenalico: caso clinico e revisione della letteratura.

Adrenal myelolipoma is a rare benign, non-functioning tumor consisting of fat and hematopoietic tissues. In January 2005 we had observed an adrenal myelolipoma in 70 year old man. During the follow-up for bladder urothelioma, an abdominal CT revaled a well delineated 4x4 cm homogeneous fatty mass in the right suprarenal area with negative attenuation values. The functional study of adrenal gland was normal. The patient underwent videolaparoscopic right adrenalectomy (Gagner technique). Postoperative course was uneventful. The istological diagnosis showed adrenal myelolipoma. We conclude that videolaparoscopic adrenalectomy should be considered the gold standard treatment for benign adrenal lesions.

[Laparoscopic treatment of liver hydatid cyst: personal technique]. / Il trattamento chirurgico laparoscopico delle cisti idatidee epatiche: tecnica personale.

Treatment of liver hydatid cyst is still controversial. Besides medical treatment, interventional radiologic techniques and traditional surgery, recently the laparoscopic approach has been proposed. Laparoscopic treatment of liver hydatid cyst, however, has not been well defined so far and seems to be associated with a recurrence rate from 0 to 9%, in a 3-49 months follow-up. Disadvantages of the laparoscopic approach are difficult control of spillage, peritoneal dissemination of parasites and incomplete aspiration of high density fluid contents of the cyst. The authors have reviewed the literature and describe a personal technique to avoid this disadvantage and to reduce postoperative recurrence rate.

[HRT in post-menopausal women: endometrial histology and bleeding patterns]. / HRT sequenziale continua della donna in post-menopausa: istologia endometriale e modalità di sanguinamento.

BACKGROUND: In this open prospective study the correlation between bleeding patterns and endometrial histology has been evaluated in 101 postmenopausal women after 2 years of continuous sequential hormone replacement therapy (HRT). METHODS: All patients received continuous transdermal 17-b-estradiol supplementation, 0.05 mg/daily, with cyclic progestogen for 12 days every month. The progestogen was: dydrogesterone 10 mg/daily (56 cases); nomegestrol 5 mg/daily (15 cases); MAP 10 mg/daily (15 cases); norethisterone 0.25 mg/daily (15 cases). The changes in the characteristics of bleeding pattern and endometrial biopsy were performed in 90 of 101 patients, at the 10-12th of progestogen therapy. RESULTS: The endometrial pattern was secretory in 60 cases, proliferative in 5 and atrophic in 22. In 3 cases the endometrial histology showed a simple hyperplasia. The bleeding generally starts 2 days after the end of progestogen therapy (13th +/- 2.9 day), with a mean duration of 4 days (4 +/- 2.8); in 21 patients (~20%) the bleeding is reduced. The endometrial histological characteristics haven't any influence on the bleeding pattern. CONCLUSIONS: In this study there was a low incidence of simple hyperplasia (3%), but the characteristics of bleeding don't permit to suspect this hyperplasia.

[Postoperative pain in laparoscopic surgery]. / Il dolore post-operatorio in chirurgia laparoscopica.

The occurrence of post-operative pain, although less severe and frequent than in open surgery, may affect length of hospital stay and early return to normal activity in some patients operated on with laparoscopic surgery. Although several pathogenetic factors have been indicated in the literature, the mechanism responsible for post-operative pain after laparoscopy; still remains unclear. In this study the Authors evaluated post-operative pain in 90 patients submitted to laparoscopic cholecystectomy and correlated it to the length of operation, endoabdominal CO2 pressure maintained during surgery, and use of local anesthesia instilled din the liver bed and in the sites of introduction of trocars. Measuring post-operative pain by means of a modified Scott-Huskisson Visual Analogue Scale, no difference in the severity of the pain was noted in the two subgroups of patients with a length of operation inferior or superior to 60 minutes, respectively. Conversely, a statistical significant difference (p = 0.04 and p = 0.049 according to Fisher exact test and Pearson test, respectively) was observed evaluating the use of local anesthesia and the level of CO2 endoabdominal pressure, with less pain in patients whose pressure was maintained under 10 mmHg and in patients treated with instillation of local anesthetic drugs in the liver bed and in the sites of introduction of trocars.

[Development of anesthesiological techniques in the surgical treatment of inguinal hernia]. / Evoluzione del trattamento anestesiologico nella terapia chirurgica dell'ernia inguinale.

The Authors describe the evolution of their anesthesiological techniques in the surgical repair of inguinal hernia. In this study they compare indications, complications, costs, hospital stay, length of surgery, postoperative pain and return to work after operations performed under local, spinal and general anesthesia. In their experience inguinal hernia treatment with local anesthesia and a tension-free technique is the preferred method of surgical repair.

[Stenotic endometriosis of the sigmoid. Apropos a case]. / L'endometriosi stenosante del sigma. A proposito di un caso.

The authors report a rare case of stenotic sigmoid endometriosis which presented with constipation and dysmenorrhea in a 48-year-old woman without past gynecological history. There were no typical radiological and endoscopic findings and only pathological examination revealed endometriosis. The patient did well after sigmoid resection and bilateral salpingo-oophorectomy and has had no further complaints. The authors stress the rare location of the disease and review the literature about etiopathogenetic hypotheses and pathological features. The diagnostic value of clinical examination, barium enema and colonoscopy is low as endometriosis rarely involves the mucosa. This case led the authors to discuss about diagnostic difficulties, differential diagnosis and therapeutic options.

[Clinical-diagnostic and therapeutic considerations in a rare case of mesenteric cyst]. / Considerazioni clinico-diagnostiche e terapeutiche su un raro caso di cisti mesenterica.

The authors report a rare case of mesenteric cyst in a 36 years old woman. These cysts have a pathogenesis that primarily may be ectopic lymphatic tissue and their most common site is in the small bowel mesentery, especially of the ileum. In the case reported the cyst was located in the right mesocolon. Mesenteric cysts can appear as chronic abdominal pain, a painless abdominal mass, or acute abdomen. Diagnostic aids include abdominal computed tomography and sonography, that usually make diagnosis of mesenteric cyst. Treatment of choice is enucleation; resection of the adjacent bowel may occasionally be necessary.

Efficacy and acceptability of transdermal estradiol in the treatment of postmenopausal bone loss.

In order to assess the effects and acceptability of transdermal estradiol on the prevention of the loss of bone mass, the Authors administered transdermal estradiol (ETTS 50 mcgr/day) for 3 weeks and, cyclically, medroxyprogesterone 10/mg/day from day 10 to day 21 of each cycle for 12 months, to 20 operated patients for bilateral ovariectomy. Primary markers of the bone turnover (hydroxyproline urinary, osteocalcin, PTH) were estimated before therapy and after 3, 6, 9, 12 months. The BMD was evaluated before therapy and after 6 and 12 months. Our study clearly shows that the transdermal administration of estradiol prevents the postmenopausal bone loss, also in postmenopausal women at higher risk of developing osteoporosis as those evaluated in our study.

[Clinico-diagnostic and therapeutic considerations on retroperitoneal liposarcoma]. / Considerazioni clinico-diagnostiche e terapeutiche sul liposarcoma retroperitoneale.

Two patients with retroperitoneal liposarcoma are presented to determine the accuracy of diagnostic methods and the role of surgical treatment. In both the patients the large retroperitoneal liposarcoma recurred locally after surgery. Histological features, clinical presentation, diagnostic procedures, extent of surgical resection and adjuvant treatment are reviewed. These data suggest that an aggressive surgical approach followed by adjuvant postoperative irradiation is the treatment of choice in primary and recurrent neoplasms.

Polycystic ovary syndrome: obesity, insulin resistance, hyperandrogenism.

The authors submitted 24 patients affected by polycystic ovary syndrome to an oral glucose tolerance test (OGTT) and determined glucose, insulin and C Peptide levels. Patients were divided in four groups according to the degree of obesity and androgenic blood levels. Eight non hirsute women with normal ovulatory function, matched for height and weight, served as controls. The authors pointed out that insulin levels were greater in the obese and hyperandrogenic PCO women than in only the obese PCO women or only the hyperandrogenic PCO women. Obese patients with PCO had higher insulin levels than obese control group. Patients with PCO nonobese and nonhyperandrogenic had higher insulin levels than nonobese control group. Insulin levels did not differ in obese PCO and hyperandrogenic PCO women. These findings suggest that at least a component of insulin resistance which is found in PCO women is independent from body weight.

[A case of retroareolar leiomyoma of the breast]. / Su un caso di leiomioma retroareolare della mammella.

The authors, showing a case of breast retroareolar leiomyoma, study the literature thereabout, and emphasize the rareness of such disease, the impossibility of a correct preoperative diagnosis and the features of absolute benignity of this lesion.

[Bochdalek's hernia with retroperitoneal contents in adults]. / L'ernia di Bochdalek a contenuto retroperitoneale nell'adulto.

The authors report a case they had the opportunity to observe, surgically treated (thoraco-phrenotomy, removal of the herniated mass, repair of the diaphragmatic breach). They illustrate the genesis of such abnormality, its incidence and symptomatology. The Authors, moreover, dwell upon the diagnostic problems caused by Bochdalek's hernia with retroperitoneal contents, and upon the advantages shown by the thoracic way of aggression in the light of their own experience.
