Treatment of Obesity with Thyroid hormones in Europe. Data from the THESIS* Collaboration.

PURPOSE: The use of thyroid hormones (TH) to treat obesity is unsupported by evidence as reflected in international guidelines. We explored views about this practice, and associations with respondent characteristics among European thyroid specialists. METHODS: Specialists from 28 countries were invited to a survey via professional organisations. The relevant question was whether "Thyroid hormones may be indicated in biochemically euthyroid patients with obesity resistant to lifestyle interventions". RESULTS: Of 17,232 invitations 5695 responses were received (33% valid response rate; 65% women; 90% endocrinologists). Of these, 290 (5.1%) stated that TH may be indicated as treatment for obesity in euthyroid patients. This view was commoner among non-endocrinologists (8.7% vs. 4.7%, p < 0.01), private practice (6.5% vs. 4.5%, p < 0.01), and varied geographically (Eastern Europe, 7.3%; Southern Europe, 4.8%; Western Europe, 2.7%; and Northern Europe, 2.5%). Respondents from Northern and Western Europe were less likely to use TH than those from Eastern Europe (p < 0.01). Gross national income (GNI) correlated inversely with this view (OR 0.97, CI: 0.96-0.97; p < 0.001). Having national guidelines on hypothyroidism correlated negatively with treating obesity with TH (OR 0.71, CI: 0.55-0.91). CONCLUSIONS: Despite the lack of evidence, and contrary to guidelines' recommendations, about 5% of respondents stated that TH may be indicated as a treatment for obesity in euthyroid patients resistant to life-style interventions. This opinion was associated with (i) respondent characteristics: being non-endocrinologist, working in private practice, treating a small number of hypothyroid patients annually and (ii) national characteristics: prevalence of obesity, Eastern Europe, low GNI and lack of national hypothyroidism guidelines.

THE LEARNING CURVE AND PERFORMANCE OF A NEWLY ESTABLISHED THYROID FINE-NEEDLE ASPIRATION CENTER.

Context: Thyroid fine-needle aspiration (FNA) cytology is the best tool for preoperative diagnosis of thyroid carcinoma; however, its learning curve is poorly described. Our aim was to assess the learning curve of a new thyroid FNA center involving unexperienced operator and pathologist. Methods: We retrieved from our tertiary endocrinology center database all thyroid FNA procedures done by a single operator (endocrinologist with no experience in FNA) between 2018 and 2021. Cytology was assessed by two pathologists with limited or no experience in thyroid cytology. We also got the corresponding sex, age, nodule diameter, EU-TIRADS score, Bethesda category and final pathology report. Results: There were 1872 FNA in 1618 patients. Proportion of Bethesda 1 nodules decreased significantly (p for trend=0.003) from 17% in the first 100 FNA procedures to 4% in the 401-500 group of procedures, and remained constant between 9% and 4% (p for trend=NS) for the rest of the study. Proportion of Bethesda 2 rose steady from 26% in the first 100 nodules to 80.1% in the last 241 nodules (p for trend<0.001). Indeterminate lesions (Bethesda 3 and 4) decreased significantly (p for trend=0.001) from 16% and 35% in the first 100 nodules to 2.5% and 5.8% in the last 241 lesions. Proportions of Bethesda 5+6 categories varied non-significantly over time. There were no time trends in the malignancy rate of surgically removed nodules. Conclusions: At least 300 procedures are needed to reach the standard performance. A steadily state for the whole center is obtained after about 500 procedures.

Osteoporotic Hip Fracture Incidence Rates in the Main Urban Area of Romania.

CONTEXT: Estimation of osteoporotic hip fracture incidence and Romanian FRAX model were based on nationally reported hospital ICD 10 coding admissions of all hip fractures (without a validation process). OBJECTIVE: We aimed to calculate, based on individual hospital charts analysis, the incidence of osteoporotic hip fracture in the main urban area of Romania and compare it with data reported to the National Institute of Public Health (NIPH). DESIGN: We retrospectively analyzed the charts of all patients (>40 years old) admitted for hip fracture in a 12-month period in hospitals with an Orthopedic Department in Bucharest and surrounding Ilfov County (11.8% of Romania population). SUBJECTS AND METHODS: All ICD 10 fracture and event/fall codes were validated against the charts. We calculated the age and sex adjusted incidence of osteoporotic hip fracture and used the national reported hip fracture data base for comparison. RESULTS: There were 2203 hip fractures of which 1997 (90.65%) were fragility fractures. The crude incidence of low-energy hip fractures was 171/100,000 (225/100,000 in women, 103/100,000 in men). The incidence rose with age to a maximum rate of 1902/100,000 in women >85 years. The NIPH-reported incidence of hip fracture was 181/100,000 for the region of interest and 176/100,000 at the national level. CONCLUSION: The incidence of osteoporotic hip fracture was lower than the incidence based on hip fractures reported codes in the national database, but the incidence of fragility fractures calculated by our group was higher than the incidence reported in previous national studies. Nationwide studies are warranted.

Use of Thyroid Hormones in Hypothyroid and Euthyroid Patients: A Thesis* Questionnaire Survey of Romanian Physicians *Thesis: Treatment of Hypothyroidism in Europe by Specialists: an International Survey.

OBJECTIVE: Romania has no national guidelines for hypothyroidism treatment, nor are there any recommendations from national societies to adhere to international guidelines. Our aim was to identify the attitudes of Romanian physicians relating to hypothyroidism treatment focusing on available formulations of levothyroxine (LT4). METHODS: All 748 members of the Romanian Society of Endocrinology were invited to participate in a web-based survey. A total of 316 (42.24%) members responded, of whom 222 (70.2%) completed all questions. RESULTS: Half of the respondents recommended LT4 treatment in euthyroid patients, from 3.6% in euthyroid patients with obesity to 36.4% in euthyroid females with infertility associated with high levels of thyroid antibodies. LT4 was considered the preferred treatment for hypothyroidism (compared to combination treatment of LT4 with LT3 or LT3 alone) by 98.6% of respondents. LT4 in liquid solution was preferred over tablets if malabsorption is suspected (56.5% vs. 27.3%), for patients with unexplained poor biochemical control (52.5% vs. 22.9%) and for patients not able to adhere to ingesting LT4 fasted (74.0% vs. 9.8%). The most and least probable explanations for persistent symptoms in patients with hypothyroidism who achieve a normal TSH under medication were "psychosocial factors" and "burden of having to take medication", respectively. CONCLUSION: A significant proportion of Romanian physicians would use LT4 in some groups of euthyroid patients, contrary to current evidence. The preferred treatment for hypothyroidism was LT4. Alternative LT4 formulations (liquid solution) are considered in specific clinical conditions. Diversification of available thyroid hormone formulations was readily incorporated into everyday practice.

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.

Numerical simulations of human tibia osteosynthesis using modular plates based on Nitinol staples.

The shape memory alloys exhibit a number of remarkable properties, which open new possibilities in engineering and more specifically in biomedical engineering. The most important alloy used in biomedical applications is NiTi. This alloy combines the characteristics of the shape memory effect and superelasticity with excellent corrosion resistance, wear characteristics, mechanical properties and a good biocompatibility. These properties make it an ideal biological engineering material, especially in orthopedic surgery and orthodontics. In this work, modular plates for the osteosynthesis of the long bones fractures are presented. The proposed modular plates are realized from identical modules, completely interchangeable, made of titanium or stainless steel having as connecting elements U-shaped staples made of Nitinol. Using computed tomography (CT) images to provide three-dimensional geometric details and SolidWorks software package, the three dimensional virtual models of the tibia bone and of the modular plates are obtained. The finite element models of the tibia bone and of the modular plate are generated. For numerical simulation, VisualNastran software is used. Finally, displacements diagram, von Misses strain diagram, for the modular plate and for the fractured tibia and modular plate ensemble are obtained.

[Surgical treatment of hyperparathyroidism]. / Tratamentul chirurgical al hiperparatiroidismului.

BACKGROUND: Hyperparathyroidism (HPT), the result of excessive secretion of the parathormone, is one of the most common endocrine disorders. In most forms of HPT, surgical parathyroidectomy is the best choice. AIM: This paper aims to examine patients with hyperparathyroidism operated in First Surgical Unit Iasi, in terms of indications, surgical technique and postoperative results. MATERIAL AND METHOD: We performed a retrospective study, in First Surgical Unit Iasi, during 2000-2008. Clinical, laboratory, intraoperative and histopathological data were included in a MS Access Office XP database. Statistical analysis was performed with the SPSS ver. 15.0 for Windows (Statistical Package for the Social Sciences, Chicago, Ilinois). RESULTS: There were examined 34 patients with HPT: 32 cases were primary HPT (94.12%), and two cases with secondary HPT (patients with renal failure). The men/women ratio was 6/28 and mean age was 50.09 +/- 2.23 years old. Clinical presentation was variable: the dominant symptoms were osteoarticular (67.6%) followed by neuropsychological (64.7%), digestive (17.6%) and renal (11.8%). Associated diseases were recorded at 47.06% of patients: arterial hypertension--32.4%, coronary heart disease--23.5%, heart rhythm disorders--17.6%, diabetes--11.8%, biliary lithiasis--5.9%, renal lithiasis--8.8% and thyroid hypertrophy--55.9%. In 8 cases, primary hyperparathyroidism was associated with other diseases of the endocrine glands: 4 cases with Multiple Endocrine Neoplasia (MEN) type 1; a patient with von Recklinghausen disease; a patient with associated hypothyroidism and diabetes; two cases that with papillary thyroid carcinoma. Positive diagnosis was supported by determining serum calcium, phosphorus and serum concentration of the parathormone (PTH). All patients were evaluated by ultrasound exam; the sensitivity of the investigation was 88.23%. 99Tc-sestamibi scintigraphy was performed in 32.35% of patients with a sensitivity of 72.72%. Parathyroidectomy was performed by Kocher's incision in 88.23% and minimally-invasive open approach in 11.76%. The following types of interventions have been performed: tumor resections (73.53%), subtotal parathyroidectomies (17.6%), total parathyroidectomies (8.82%). In patients with associated thyroid disease total thyroidectomies (26.5%) and subtotal thyroidectomies were done (11.8%). The postoperative morbidity rate was 2.9% (transient hypocalcemia). Histopathological examination revealed the presence of parathyroidian adenoma in 67.6% of patients (N=23), parathyroidian hyperplasia in 26.5% (N=9) and parathyroidian carcinoma in the others 5.9% (N=2). CONCLUSIONS: The diagnosis of HPT involves positive determination of calcium and PTH. The most useful imaging techniques, are 99Tc-sestamibi scintigraphy and ultrasonography, which locates in most cases, the parathyroid pathological glands. Surgical treatment is the only curative treatment of HPT, with medical treatment only role in preoperative preparation. The precise site of the parathyroidian lesion facilitates minimally-invasive approach. The postoperative follow-up is mandatory because of the increased potential for recurrence and for diagnosis of other endocrine tumors (in patients with MEN).

[Surgical treatment of gynecomastia]. / Tratamentul chirurgical al ginecomastiei.

BACKGROUND: Gynecomastia describes a benign increase of the mammary gland in men. When medical treatment fails, the surgical procedure is the treatment of choice. There are two main surgical procedures: subdermal mastectomy and liposuction. AIM: To evaluate the results after surgical treatment (mastectomy) performed in a general surgery unit. METHOD: We performed a retrospective study; all the patients operated for gynecomastia were reviewed. The clinical, imaging, biological, intraoperative and histological data were included into a MS Access database and statistical analyzed. RESULTS: From 1990-2007, 114 patients were admitted in the First Surgical Clinic Iasi for gynecomastia. Only 12.6% from the patients were with bilateral gynecomastia. The mean age was 40.54 +/- 1.83 years old (range 12-84). Mean body mass was 26.72 +/- 0.46 kg/m2 (range 18.5-41), and about 20% from the patients had a BMI of over 30 kg/m2. We also noted that 46.5% were smokers. Simon classification was used for preoperative staging: 2.6% from the cases (N = 3) were included in stage I, 16.7% (N = 19) in stage IIa, 50% (N = 57) in stage IIb and 30.7% in stage III. The patients included in stages IIa and I are younger then the patients included in stage III (p = 0.024). Mastodynia was noted in 46 cases (40.4%). Ultrasound exam was performed in all the cases, and the larger diameter of the nodule measured was 3.75 +/- 0.18 cm (range 0.5-9.7). Only three cases were preoperatively treated with tamoxifen. Most of the cases were operated using general anesthesia (53.5%). Mastectomy was performed by peri-areolar (70.2%), elliptical (28.9%) or radial (0.9%) incisions. The subdermal mastectomy using peri-areolar approach was performed especially for the cases included in stages I, IIa and IIb--p < 10(-3). The epi-pectoral vacuum drainage has been used in 79.8%. The postoperative morbidity rate was 15.8%--4 cases of hematoma, 13 cases of seroma and 1 case complicated with skin necrosis. No specific risk factors for postoperative complications were found by univariate and multivariate statistical analysis. The pathological exam revealed pseudo-gynecomastia in 6 cases; the other cases presented dilated ducts. We also noted intraductal papillary hyperplasia in 87 cases and chronic inflammation in 35 cases. The histological exam also revealed intraductal papilloma--9 cases, fibro-adenoma--1 case, papillary ductal carcinoma--1 case and mucinous carcinoma--1 case. From all these data, the etiological diagnosis in presented series was: pseudo-gynecomastia--5.3% (N = 6), idiopathic--64.9% (N = 73), endocrine--7.9% (N = 9), drug induce--5.3% (N = 6), metabolic--7.9% (N = 9), tumoral--8.8% (N = 10). The postoperative hospital stay was 4.04 +/- 0.26 days (range 1-12). A literature review has also been performed. CONCLUSIONS: The management of gynecomastia has to be performed by a multidisciplinary team. Gynecomastia it is possible to be associated with a breast cancer, even in younger people. The surgical treatment, especially the type of incision, will be chosen from point of view of Simon stages. Liposuction can be associated in selected cases.

Insulin resistance and insulin secretion in non-diabetic acromegalic patients.

UNLABELLED: Insulin resistance (IR) can be induced by high amounts of growth hormone (GH). AIM: To set up, in acromegaly without diabetes mellitus, a correlation between the disease activity in GH-secreting adenoma (AA) - assessed by minimum GH serum level during an oral glucose tolerance test (OGTT) - and severity of insulin resistance (IR), assessed by HOMA-IR index. METHODS: 75 out of 88 consecutive patients with acromegaly hospitalized in our department were included in this study. 13 patients proved to have diabetes mellitus and were excluded. Serum glucose, GH and insulin levels were measured by immunoradiometricassay basal and at 30, 60 and 120 minutes after a 75 g OGTT in 88 patients with active or cured acromegaly. IR was assessed using HOMA-IR index (Homa-IR=basal serum glucose (mg/dl) x basal serum insulin (mU/L)/22.5 x 18). A value over 2.5 was considered indicating IR. RESULTS: Out of 75 patients without diabetes mellitus, 36 subjects (48%) were presenting with IR (34 with active disease, 2 cured). We found a significant positive correlation (r=0.56, p<0.001) between AA and HOMA-IR. The GH minimal level corresponding to the intersection of the exponential regression curve with the HOMA-IR level of 2.5 was 8.8 ng/mL, a cut-off point indicating IR with 82% specificity and 78% sensitivity. The odds ratio for developing IR becomes significant at a minimum GH level during OGTT of 2 ng/mL (odds ratio 7.6, 95% confidence interval 2-29). CONCLUSIONS: The severity of IR revealed by acromegaly correlates with GH production. A GH serum level higher than 2 ng/mL during OGTT indicates an increased risk for developing IR. This cut-off level of GH can be used as one of criteria of cured disease, regarding the lack of metabolic effects.

Ovarian fibroma in the era of laparoscopic surgery: a general surgeon's experience.

The ovarian fibroma is a rare benign tumor originating from the connective tissue of the ovarian cortex. On occasion, the general surgeon may encounter ovarian fibroma while operating an acute abdomen. We present a series of 15 ovarian fibromas encountered in 13 patients over 11 years experience in our general surgical ward. Only four cases required emergency operations due to either tumors or adnexal torsion. High-resolution ultrasound scan with color Doppler suggested an ovarian fibroma in only ten cases, while CT and MRI were suggestive for the diagnosis in three other cases. Surgical treatment consisted of five ovarectomies, three adnexal resections and five total hysterectomies with bilateral salpingo-oophorectomy. Seven patients underwent laparoscopic surgery, four of them for an ovarian resection and in three for an adnexectomy. Laparoscopic approach has significant advantages by limiting parietal aggression with better cosmetic results, short hospital admission, lower costs, few postoperative adhesions and rapid recovery.

[Pancreaticoduodenectomy with or without pylorus preservation: a retrospective analysis of 137 patients]. / Duodenopancreatectomia cefalica cu sau fara prezervarea pilorului: analiza retrospectiva a 137 pacienti.

OBJECTIVE: We performed a retrospective study to assess the postoperative results, long-term survival and quality of life after pylorus preserving pancreaticoduodenectomy (PPPD) versus standard Whipple pancreaticoduodenectomy (WPD). METHODS: A retrospective study was performed in a nonselected series of 137 patients who were operated in the Surgical Clinics of "St. Spiridon" University Hospital Iasi, Romania, from January 1st, 1995 till December 31, 2005. Demographics, preoperative and intraoperative data, as well as postoperative morbidity, mortality and follow-up were analyzed. Quality of life, after to at least six months after discharge, was also studied. RESULTS: There were no significant differences noted in demographics data. Jaundice was more frequent in the PPPD group as for WPD patients (p=0.047). For the most patients the digestive reconstruction after resection were performed as in Child technique: the first anastomosis was pancreaticojejunostomy (end-to-end or end-to-side), the second anastomosis was hepaticojejunostomy (end-to-side) and the last anastomosis was gastrojejunostomy end-to-side (duodenojejunostomy in PPPD group). For 31 cases a pancreatico-gastrostomy were performed. We also noted 14 cases with pancreatico-gastrostomy and duodenojejunostomy end-to-end, and a Roux jejunal loop for 3 patients with previous gastrectomy and gastrojejunostomy (Reichel-Polya). The operating time was shorter in the PPPD group as in WPD (p < 10-3), but the mean blood loss was the same. Postoperative morbidity rate was 46.8% in PPPD group vs 39.2% in WPD (p > 0.05), but the reintervention rate was significant higher in PPPD group (30.6% vs 15%; p = 0.027). We also noted no significant differences of Delayed Gastric Emptying, postoperative mortality rate (14.5% in PPPD group vs 10.1% in WPD group) and mean survival time (42.42 months (24.94 - 59.89; 95% CI) in PPPD group vs 46.78 months (28.07 - 61.50; 95% CI) in WPD group; log rank test p = 0.643). Pathological exam diagnosed a malignancy in 109 cases (54 cases with pancreatic cancer); we noted chronic pancreatitis in 22 cases. Quality of life was also the same in the two groups. CONCLUSIONS: PPPD and WPD were associated with comparable results, but, there is a tendency of increase rate of postoperative morbidity and mortality for PPPD patients. We also noted that postoperative quality of life is the same for both procedures.

The arthroscopy-histological criterion link in endoscopic "repair" treatment of chondral and chondralbone lesions of the knee.

The authors present the results of optical microscopic studies of some lesions of cartilage and subchondral bone of the knee, the arthroscopy allowing this structure's biopsy during the endoscopic procedures. These histological criteria are very important estimation factors of long term results of these "repair" techniques, the microstructure showing the real biological status of these specific tissues.

[Pancreatic endocrine tumors]. / Tumori pancreatice endocrine.

Incidence of the endocrine tumors of the pancreas is about 4 to 10/1.000.000 peoples. We present 10 cases of endocrine pancreatic tumors which were operated in the First Surgical Clinic Iasi in the last 20 years (1984-2003); these cases represent about 2.21% from all the pancreatic tumors (454 cases). It was 4 insulinoma, 2 gastrinoma, 2 gastrinoma associated with other endocrine neoplasia (Wermer syndrome) and 2 non-functioning endocrine pancreatic tumors. Female/men ratio was 9/1 and median age was about 41.9 yo (27-67 yo). In the four cases of insulinoma (all females) the diagnosis was delayed by two to five years due to misinterpretation of neurological symptoms generated by hypoglycemia. The diagnosis of insulinoma was based on Whipple triad, high plasma insulin levels associated with low plasma glucose levels, as well as the symptomatic relief after intravenous glucose injection. The surgical option was based on biological data, ultrasonography, computed tomography and arteriography. In two cases the localization of the insulinoma was established only by intraoperative ultrasonography. All tumors were localized in the tail of pancreas. In three cases we decided for a distal pancreatic resection with splenectomy and in one case for spleen preserving left pancreatectomy. Postoperative course was uneventful and all the symptoms disappeared. The diagnosis was confirmed on pathological examination in all cases. We also present two cases of gastrinoma with multiple ulcers and multiple surgical interventions for haemorrhage and perforation with peritonitis. Both patients died and diagnosis of pancreatic endocrine tumors was post-mortem. The two patients with Wermer syndrome also had ulcers complicated with haemorrhage and peritonitis and parathyroid adenoma. One case also had ante-hypophyseal and pituitary adenoma and the other had thyroid colloid hypertrophy. We performed left pancreatectomy with spleen preservation in one case and enucleation associated with total gastrectomy in the second case. The two cases of non-functioning pancreatic endocrine tumors had a non-specific symptoms. Diagnostic was established by abdominal ultrasound exam. We performed spleno-pancreatectomy in one case and pancreatectomy with spleen preservation in the other patient. Postoperative course was un-eventful.

[Incidence and management of the ovarian fibroma and thecoma. Experience of The First Surgical Clinic Iasi]. / Fibroamele si tecoamele ovariene in experienta Clinicii I Chirurgie Iasi. Incidenta si conduita.

The ovarian fibroma, thecoma and fibro-thecoma are a rare benign tumors growing from the connective tissue of the ovarian cortex. The general surgeon may confront in his practice solid ovarian mass, sometimes in emergency. Between 1995 and 2005, we report thirteen cases of ovarian fibroma (two bilateral) and two ovarian thecoma with mean age 53 years operated in First Surgical Clinic Iasi. Four of them were operated on as emergencies. Clinical ascites are found in three patients with large tumors. The early symptoms were pelvic pain and abnormal uterine bleeding. Patients with large tumors or ascites were admitted with compression symptoms or abdominal distension. Ultrasonography showed a solid uniformly hypo-echogenic mass, with very marked sound attenuation. We performed oophorectomy in six cases (laparoscopic approach in four cases) and salpingo-oophorectomy in nine cases (using laparoscopic stapler in three cases). There were no conversions to laparotomy. In all cases the diagnosis was established by histological examination. Laparoscopic approach is associated with significantly less operative morbidity, less postoperative pain, shorter hospital stays and shorter recovery periods, best cosmetic results.

[Conversion in laparoscopic cholecystectomy]. / Conversia in colecistectomia laparoscopica.

Laparoscopic cholecystectomy (LC) has become the gold standard in the treatment of symptomatic cholelithiasis. Some patients require conversion to open surgery and several preoperative variables have been identified as risk factors that are helpful in predicting the probability of conversion. The aim of this study was to analyze the factors that make LC difficult and determine conversion to open approach: Our study includes: 6985 cases which underwent LC and 1430 cases with open cholecystectomy, between March 1993 and April 2005 in our clinic of general surgery. The overall conversion rate was 5.1% (deliberate conversion--299 cases, conversion of necessity--62 cases). The conversion rate has decreased from 17.5% in 1993 to 3.2% in recent years. The most conversion happen after a simple inspection or a minimal dissection caused by the existence of perforation (105 cases), the discovery of a difficult anatomic situation (63 cases) or of another pathology (14 cases); more rarely, the conversion was necessary in the principal time, doing to hemorrhage (26 cases), impossible dissection (41 cases), visceral injury (1 case) or even at the end of the operation, doing to hemorrhage, loss piece or stone (10 cases), and other situations (101 cases). Significant predictors of conversion were acute cholecystitis , choledocholithiasis, past history of acute cholecystitis, male gender, gall bladder wall thickness exceeding 6 mm. In conclusion, based on our experience, we suggest limiting OC to patients with proven contraindications to LC (i.e., Mirizzi syndrome or systemic illness incompatible with general anesthesia or pneumoperitoneum), attempting LC in all other cases. Decision to convert to open approach is a proven of surgical maturity. Conversion must be decided from the beginning, in the moment of the recognition of a difficult situation and not after the occurrence of a complication.

Humoral immune response in human pulmonary tuberculosis: antibodies against Mycobacterium tuberculosis polysaccharide, protein and glycolipid antigens.

Sera from 67 tuberculosis patients and 30 healthy subjects have been analyzed for the presence of specific antibodies against polysaccharide, protein and glycolipid antigens from H37Rv strain of Mycobacterium tuberculosis. The results proved the advantages of using the glycolipid antigens in diagnosing tuberculosis as well as the relationship between the antibodies level and the extension of the pulmonary tuberculous lesions.

Clinical usefulness of rapid serodiagnosis in pulmonary tuberculosis by ELISA with glycolipidic antigens extracted from Mycobacterium tuberculosis and with whole BCG suspension.

Antibodies against Mycobacterium tuberculosis glycolipids and whole BCG suspension were determined by ELISA on 58 sera from hospitalized patients with presumptive pulmonary tuberculosis and on 127 sera from control subjects. The experimental results demonstrated that the glycolipids are more adequate to be used as antigens than whole BCG suspension, as high sensitivity of the test was obtained. By using only one antigen, ELISA becomes more efficient in rapid diagnosis. ELISA with glycolipidic antigens should be used as a supporting test for direct smear examination in the diagnosis of pulmonary tuberculosis, especially in cases when repeated bacterial methods failed to prove the presence of M. tuberculosis.
