Structured reporting of chest CT in COVID-19 pneumonia: a consensus proposal

OBJECTIVES

The need of a standardized reporting scheme and language, in imaging of COVID-19 pneumonia, has been welcomed by major scientific societies. The aim of the study was to build the reporting scheme of chest CT in COVID-19 pneumonia.

METHODS

A team of experts, of the Italian Society of Medical and Interventional Radiology (SIRM), has been recruited to compose a consensus panel. They used a modified Delphi process to build a reporting scheme and expressed a level of agreement for each section of the report. To measure the internal consistency of the panelist ratings for each section of the report, a quality analysis based on the average inter-item correlation was performed with Cronbach's alpha (Cα) correlation coefficient.

RESULTS

The overall mean score of the experts and the sum of score were 3.1 (std.dev. ± 0.11) and 122 in the second round, and improved to 3.75 (std.dev. ± 0.40) and 154 in the third round. The Cronbach's alpha (Cα) correlation coefficient was 0.741 (acceptable) in the second round and improved to 0.789 in the third round. The final report was built in the management of radiology report template (MRRT) and includes n = 4 items in the procedure information, n = 5 items in the clinical information, n = 16 in the findings, and n = 3 in the impression, with overall 28 items.

CONCLUSIONS

The proposed structured report could be of help both for expert radiologists and for the less experienced who are faced with the management of these patients. The structured report is conceived as a guideline, to recommend the key items/findings of chest CT in COVID-19 pneumonia.

Colo-rectal endoscopic full-thickness resection (EFTR) with the over-the-scope device (FTRD®): A multicenter Italian experience

BACKGROUND AND AIM

Endoscopic full-thickness resection(EFTR) with FTRD^® in colo-rectum may be useful for several indications.The aim was to assess its efficacy and safety.

MATERIAL AND METHODS

In this retrospective multicenter study 114 patients were screened; 110 (61M/49F, mean age 68 ± 11 years, range 20-90) underwent EFTR using FTRD^®. Indications were:residual/recurrent adenoma (39), incomplete resection at histology (R1 resection) (26), non-lifting lesion (12), adenoma involving the appendix (2) or diverticulum (2), subepithelial lesions(10), suspected T1 carcinoma (16), diagnostic resection (3). Technical success (TS: lesion reached and resected), R0 resection (negative lateral and deep margins),EFTR rate(all layers documented in the specimen) and safety have been evaluated.

RESULTS

TS was achieved in 94.4% of cases. EFTR was achieved in 91% with lateral and deep R0 resection in 90% and 92%. Mean size of specimens was 20 mm (range 6-42). In residual/recurrent adenomas, final analysis revealed: low-risk T1 (11), adenoma with low-grade dysplasia (LGD) (24) and high-grade dysplasia (HGD) (3), scar tissue (1). Histology reports of R1 resections were: adenoma with LGD (6), with HGD (1), low-risk (6) and high-risk (1) T1, scar tissue (12). Non-lifting lesions were diagnosed as: adenoma with HGD (3), low-risk (7) and high risk (2) T1. Adverse clinical events occurred in 12 patients (11%),while adverse technical events in11%. Three-months follow-up was available in 100 cases and residual disease was evident in only seven patients.

CONCLUSIONS

EFTR using FTRD^® seems to be a feasible, effective and safe technique for treating selected colo-rectal lesions. Comparative prospective studies are needed to confirm these promising results.

Characteristics of Migraine in an Out-Patient Population Over 60 Years of Age

One hundred and sixty-three consecutive patients (129 females and 34 males) over 60 years of age attending the Headache Centre of the University of Perugia in the period January 2000-December 2001 were included in the study.

One hundred and fifty-two (93.3%) were affected by a primary headache disorder. According to the 1988 IHS Criteria, their prevailing attacks could be diagnosed as migraine without aura (MwoA) in 57.2% of cases ( n = 87) and as migraine with aura (MwA) in 11.8% of cases ( n = 18). Attacks both in MwoA and MwA were unilateral and of severe-to-moderate intensity in 45% and 50% of cases. Head pain was referred as pulsating by 56% and 38.9% of MwoA patients MwA patients, respectively. Aggravation with routine daily activities was present in 72.4% and 61.1% in MwoA and MwA patient groups. The most frequent accompanying symptoms were photophobia and phonophobia. Headache attacks were of shorter duration in MwA patients, but in 3.4% of MwoA patients attacks lasted between 2 and 4 h. Of patients affected by MwA, 55% referred, together with the typical attacks, symptoms of aura not followed by headache. A worsening of headache in the last 5 years was reported by 67.8% and 44.4% of MwoA and MwA patients, respectively. Of the patients with MwoA, 86.2% ( n = 75), and 83.3% ( n = 15) of those with MwA used symptomatic drugs for their attacks. In the majority of cases they took more than one analgesic or non steroidal anti-inflammatory drug. A total of 51.7% of patients with MwoA and 55.5% of patients with MwA were under prophylactic treatment. Preventive drugs included antidepressants, beta-blockers, calcium channel antagonists and antiepileptic drugs. The choice of symptomatic or prophylactic drugs was made, in the majority of cases, on the basis of concomitant diseases.

Cartilage ossiculoplasty in cholesteatoma surgery: hearing results and prognostic factors

Cartilage tympanoplasty is an established procedure for tympanic membrane and attic reconstruction. Cartilage has been used as an ossiculoplasty material for many years. The aim of this study was to evaluate hearing results of costal cartilage prostheses in ossicular chain reconstruction procedures in subjects operated on for middle ear cholesteatoma and to determine the presence of prognostic factors. Candidates for this study were patients affected by middle ear cholesteatoma whose ossicular chain was reconstructed with a chondroprosthesis. 67 cases of ossiculoplasty with total (TORP) or partial (PORP) chondroprosthesis were performed between January 2011 and December 2013. Follow-up examination included micro-otoscopy and pure tone audiometry. The guidelines of the Committee on Hearing and Equilibrium of the American Academy of Otolaryngology Head and Neck Surgery were followed and pure-tone average (PTA) was calculated as the mean of 0.5, 1, 2 and 4 kHz thresholds. Statistical analysis was performed with ANOVA tests and regression models. Average air-bone gap (ABG) significantly improved from 39.2 dB HL (SD 9.1 dB HL) to 25.4 dB HL (SD 11 dB HL) (p < 0.001). Linear regression analysis showed that the only prognostic factor was the type of operation (p = 0.02). In fact, patients submitted to ICWT presented better post-operative ABG compared to CWDT. None of the other variables influenced the results. The present study proposes costal cartilage as material of choice when autologous ossicles are not available. The maintenance of the posterior canal wall was the only prognostic factor identified.

Sexual function in patients who underwent surgery for stress urinary incontinence

AIM

Stress urinary incontinence (SUI) has been reported to have a negative impact on sexual relations in up to 68% of women. The effect of suburethral sling on sexual functioning has been studies, but the results are still inhomogeneous. This study was undertaken to assess the effect of the transvaginal tension free vaginal tape (TVT), transvaginal tension free vaginal tape - obturate (TVT-O) and minisling procedures (SIS) on sexual function and to also evaluate the male experience respect to sexual activity before and after surgery of partners of women underwent surgery.

METHODS

We enrolled 150 patients underwent a TVT/TVT-O or SIS for female stress urinary incontinence. All patients enrolled were invited to fill out the Female Sexual Function Index (FSFI) Questionnaire, before surgery and 12 months after surgery. We also evaluate the male experience, through questionnaire, respect to sexual activity before and after surgery of female partner.

RESULTS

At month 12, the mean follow-up FSFI total score in SIS group improved from baseline 22.7±3.83 to 26.2±4.01 (P=0.001), in the TVT group from baseline 22.5±4.11 to 28.5±3.87 (P=0.001) and in the TVT-O group from baseline 23.5±4.48 to 27.7±3.68. The male questionnaires reported an improvement of the sexual function of 84% for TVT group, 82.9% for SIS group and 80,9% for TVT-O group.

CONCLUSION

In our present study, patients underwent TVT, TVT-O or SIS showed comparable significant improvement of sexual function after sling procedure as evaluated by FSFI.

Involvement of Corticotrophin-Releasing Factor and Orexin-A in Chronic Migraine and Medication-Overuse Headache: Findings From Cerebrospinal Fluid

The study set out to investigate the role of corticotrophin-releasing factor (CRF) and orexin-A in chronic migraine (CM) and medication-overuse headache (MOH). Twenty-seven patients affected by CM and 30 with MOH were enrolled. Control CSF specimens were obtained from 20 age-matched subjects who underwent lumbar puncture for diagnostic purposes, and in all of them CSF and blood tests excluded central nervous system or systemic diseases. Orexin-A and CRF were determined by radioimmunoassay methods. Significantly higher levels of orexin-A and CRF were found in the CSF of MOH and to a lesser extent in patients with CM compared with control subjects (orexin-A: P < 0.001 and P < 0.02; CRF: P < 0.002 and P < 0.0003). A significant positive correlation was also found between CSF orexin-A values and those of CRF ( R = 0.71; P < 0.0008), monthly drug intake group ( R = 0.39; P < 0.03) and scores of a self-completion 10-item instrument to measure dependence upon a variety of substances, the Leeds Dependence Questionnaire (LDQ) in the MOH group ( R = 0.68; P < 0.0003). The significantly higher orexin-A levels found in CM and MOH can be interpreted as a compensatory response to chronic head pain or, alternatively, as an expression of hypothalamic response to stress due to chronic pain. A potential role for orexin-A in driving drug seeking in MOH patients through activation of stress pathways in the brain can also be hypothesized.

Malignant progression of a small HCC nodule: hypovascular 'early HCC' converted to hypervascular 'small HCC' within six months

We report a case of hepatocellular carcinoma superimposed on chronic hepatitis C virus (HCV) hepatitis in which final diagnosis of hepatocellular carcinoma was delayed because there was no consensus on hypervascularity with two diagnostic methods at the time of presentation. A 3 cm lesion was initially observed as hypovascular at multidetector-row computed tomography. Conversely, two months later the lesion appeared hypervascular at contrast-ultrasonography and gadolinium-enhanced dynamic magnetic resonance, and hyperintense after superparamagnetic iron oxide-enhanced T2W studies. Only in the late follow-up it was definitively confirmed as hypervascular in the arterial phase of multidetector-row computed tomography. This case clearly highlights some pitfalls in the European Association for the study of the liver guidelines for hepatocellular carcinoma management, which were readdressed in the last American Association for the Study of Liver Diseases (AASLD) and in the forthcoming international proposals, leading to more pragmatic suggestions for clinical practice.

NF-kappaB activity and iNOS expression in monocytes from internal jugular blood of migraine without aura patients during attacks

This study investigated nuclear factor-kappa B (NF-kappaB) activity by electrophoresis mobility gel shift assay and IkappaBalpha expression by Western blot analysis in monocytes obtained from serial samples of internal jugular venous blood taken from seven migraine patients without aura during attacks. Inducible nitric oxide synthase (iNOS) expression was also assessed by reverse transcription-polymerase chain reaction. An increase in NF-kappaB activity peaked 2 h after attack onset. This was accompanied by a transient reduction in IkappaBalpha expression. Up-regulation of iNOS was evident at 4 h, maintained at 6 h and reduced at the end of the attack. These findings substantiate the hypothesis of transitory delayed inflammation, as suggested by the animal model, and suggest the possibility of using therapeutic approaches to target NF-kappaB transcription in the treatment of migraine.

Weight loss in obese children carrying the proopiomelanocortin R236G variant

To acquire more information relative to the course of obesity in conditions of food restriction in subjects carrying mutations in the melanocortin signaling pathway, 710 obese children (mean age: 9.5+/-2.1 yr; mean z-score body mass index: 3.63+/-1.6) were genotyped for the proopiomelanocortin (POMC) R236G substitution, a variant which has been associated to early onset obesity, by restriction fragment length polymorphism (RFLP) analysis. Three children were heterozygotes for the R236G variant (0.4%). One of them had the metabolic syndrome. This variant was not found in 400 controls. The 3 probands followed a hypocaloric balanced diet and, after about 12 months, normalized their weight as well as fat mass and insulin resistance. The patient with the metabolic syndrome reversed this condition. These results show that a) the R236G substitution of POMC gene, although not a major cause of obesity among Italian obese children and adolescents, is associated with early onset obesity, and that b) inherited alterations of the melanocortin signaling pathway, independently of the degree of obesity, do not preclude the possibility to lose weight in mutated individuals following a hypocaloric diet.

Follicular fluid vascular endothelial growth factor concentrations are increased during GnRH antagonist/FSH ovarian stimulation cycles

BACKGROUND

The aim of this study was to investigate the effect of GnRH antagonists (GnRH-ant) on follicular fluid vascular endothelial growth factor (FF VEGF).

METHODS

Sixty women undergoing assisted reproduction were randomised (computer-generated randomisation list) and assigned to two different GnRH analogue regimens: GnRH agonist (GnRH-a) (Group A; n = 30) and GnRH-ant (Group B; n = 30).

RESULTS

Mean (+/-S.D.) FF VEGF concentrations were 1598+/-612 pg/mL and 2906+/-1558 pg/mL for Groups A and B, respectively (p < 0.001). In the women treated with GnRH-ant, we found a statistically significant reduction in serum LH levels (1.72+/-0.74 IU/L in Group A versus 0.93+/-0.43 IU/L in Group B, p < 0.001), in serum oestradiol (E2) levels (1562.1+/-410.7 pg/mL in Group A versus 1214.67+/-779.9 pg/mL in Group B, p < 0.05), in FF E2 levels (1146+/-593 ng/mL in Group A versus 621+/-435 ng/mL in Group B, p < 0.05), and in FF androstenedione levels (136+/-55 ng/mL in Group A versus 78+/-31 ng/mL in Group B, p < 0.001), as well as a reduction in the number of pregnancies, though not statistically significant (23.3% in Group A versus 16.6% in Group B).

CONCLUSION

The increase in FF VEGF levels in women treated with GnRH-ant might be explained by a suppression of LH and E2 levels.

Follicular fluid levels of vascular endothelial growth factor and early corpus luteum function during assisted reproductive technology cycles

Background

The relation between vascular endothelial growth factor (VEGF) and early luteal function has rarely been proven in humans. The purpose of this study was to define the relation between follicular fluid concentrations of VEGF (FF VEGF) and early luteal function at the preimplantation stage during assisted reproductive technology (ART) cycles.

Methods

71 women were divided into two groups, based on reproductive outcome: women who became pregnant after embryo transfer (ET) (n = 18, Group A) and non-pregnant women (n = 53, Group B). Serum progesterone (Se P) and inhibin A on ET day, and FF VEGF levels were measured in all women. Data were expressed as mean ± standard deviation. Statistical analysis was performed using Excel Office 98 for Student's t-test, linear regression test and chi-square test. A p value of < 0.05 was considered statistically significant.

Results

The groups were comparable for age, ovarian reserve, number and quality of the oocytes retrieved and of the embryos obtained and transferred. FF VEGF levels were increased (4235 ± 1433 vs 3432 ± 1231 pg/ml), while Se P and inhibin A levels were significantly reduced (83.1 ± 34.1 vs 112.0 ± 58.8 ng/ml and 397.4 ± 223 vs 533.5 ± 283 pg/ml, respectively) in the non-pregnant group and were negatively correlated with FF VEGF (r = -0.482, p < 0.05; r = -0.468, p < 0.05) only in pregnant women.

Conclusion

Much has to be learned about the regulation and role of VEGF during the early luteal phase. We advance the hypothesis that the existence of a negative correlation between FF VEGF/Se P and FF VEGF/inhibin A in pregnant women might indicate the existence of a normal VEGF-mediated paracrine response when Se P and inhibin A levels are decreased. Excess production of FF VEGF and the absence of a correlation between FF VEGF/Se P and FF VEGF/inhibin A in non-pregnant women may be a paracrine reaction to immature luteal vasculature, resulting in luteal dysfunction.

The treatment of NAFLD

Nonalcoholic fatty liver disease (NAFLD) is becoming an increasing cause of chronic liver damage. The decision of start a medical treatment is based on the documented risk of progression to cirrhosis and liver cancer, when steatohepatitis (NASH) occurs. The therapy of this syndrome requires, as obviously, some considerations on the natural history of the condition, on the efficacy and safety of various therapeutic options, as well as on the costs. Treatment of patients with NAFLD has typically been focused on the management of associated conditions such as obesity, diabetes mellitus and hyperlipemia. Weight loss improves insulin sensitivity, and NASH may resolve with weight reduction. Insulin resistance seems to be the common denominator in many cases of NAFLD. Two classes of drugs have been shown to correct insulin resistance: biguanides (e.g., metformin) and thiazolidinediones (e.g., rosiglitazone and pioglitazone). The last two decades have witnessed a considerable progress in the understanding of the mechanisms respon-sible for the fibrogenic progression of chronic liver diseases. Several drugs believed to be hepatoprotective or antifibrotic agent as UDCA, betaine, vitamin E, lecithin, beta-carotene and selenium have been used in patients with NASH. Silybin is the main component of silymarin that is absorbed when linked whith a phytosome. This substance reduces in rats the lipid-peroxidation and the activaction of hepatic stellate cells. In humans, some non controlled data show that silybin is able to reduce insulin resistance, liver steatosis and plasma markers of liver fibrosis.

Major salivary gland diseases. Multicentre study

This multicentre study involved 28 Italian ORL Centres responding to a questionnaire sent by us which allowed recruitment of a high large number of cases of parotid neoplasms observed over a 10-year period. Statistical data obtained partly confirmed previous findings. Benign tumours account for 80% of case histories with a relationship 1:4 M/F, the most frequent being pleomorphic adenoma (57.3% of cases), followed by Warthin's tumour (32.4%), this rating not having been confirmed in case histories (8-10%) in the literature. Malignant tumours instead were fewer in number compared to the literature (14% vs 25-30%); the most frequent being mucoepidermoid carcinoma (18.2%) of which 44% G1, 33% G2 and 23% G3. Adenoid-cystic carcinoma was observed in 15.3% and < or = 10% for all the other most frequent histological malignant neoplasms. Diagnostic work-up included echotomography and fine-needle aspiration biopsy, less used imaging techniques were computed tomography, magnetic resonance imaging, Sialo-computed tomography. During this multicentre investigation more widespread use of imaging techniques has, however, been observed. The greater use of ecotomography and of fine-needle aspiration biopsy was due to simplicity of application and low cost offering good sensitivity and specificity. Surgical treatment of benign tumours consisted, in 50% of cases, in superficial paroditectomy and in approximately 30% of total paroditectomy. Enucleoresection was limited to approximately 15% of neoplasms, enucleation to <10% of cases with only 2% of pleomorph adenoma due to the well-known anatomo-pathological characteristics which may lead to relapse. For malignant neoplasms, total parotidectomy was performed in approximately 50% of cases, while in the remaining 50% an almost equal rate of superficial parotidectomy was carried out and enlarged parotidectomy, with or without sacrificing the facial nerve, which was rebuilt in 60% of cases. The lateral neck dissection most frequently carried out was of functional type in 54% and selective type in 46% with removal of levels I-III and II-IV in approximately 60% of cases. Sentinel lymph node was observed in a limited number of centres. When no clinically evident lymph nodes were present (NO) considering the tumour histotype, two thirds of patients underwent surgery or radiotherapy, while in the remainder the wait-and-see attitude was prefered. Post-operative-complementary radiotherapy was very frequently performed instead of chemotherapy. Oncological results obtained were compared with those reported in the literature: in fact for all benign neoplasms relapse ratings are about 5%, while for malignant tumours the worst prognosis was in squamous cell carcinoma with median of 37.7 on survival and metastasis rate of 16.5%. Finally, mucoepidermoid carcinoma tumours showed best survival, followed by adenoid-cystic carcinoma with ranges, respectively, 83 and 81.

Platelet-activating factor (PAF) in internal jugular venous blood of migraine without aura patients assessed during migraine attacks

The aim of the study was to verify the production of PAF and the activity of PAF acetyl-hydrolase (PAF-AH), the enzyme involved in the catabolism of this phospholipid mediator, in migraine attacks. Their levels were determined during migraine crises in serial samples of internal jugular venous blood taken from five migraine patients without aura, who were admitted to the hospital during the crises. Internal jugular venous blood samples were taken immediately after catheter insertion at 1, 2, and 4 h after attack onset, and within 2 h from its cessation. PAF was purified by high-performance liquid chromatography (HPLC) and determined by radioimmunoassay method. The enzymatic activity of PAF-AH was measured by reverse-phase HPLC, based on the derivatization with 7-diethylaminocoumarin-3-carbonylazide. In the internal jugular venous blood of migraine patients without aura (MO), an increase was observed in PAF levels, which was already evident at the time of catheter insertion (885.6 +/- 82.8) and at the first hour (868.4 +/- 65.24) (ANOVA: P < 0.0001). PAF levels remained elevated through the second (746.8 +/- 82.95), fourth (700.6 +/- 34.93) and sixth hours (644.4 +/- 42.85), and then decreased at the end of the attack, reaching levels significantly lower than those measured at the time of catheter insertion (565.5 +/- 38.34). The activity of PAF-AH showed an opposite trend with higher values at the first hour and significantly lower values at the second and fourth hours from the beginning of the migraine attack (ANOVA: P < 0.02). The increased production of PAF may account for persistent platelet activation during migraine crises, even in the presence of an increased production of nitric oxide (NO) end-products which, on the other hand, should instead intervene in counteracting and limiting platelet activation. Potential sources of PAF production are the endothelial cells from cerebral vessels, stimulated by trigeminal neuropeptides, platelets themselves, and mast cells, as suggested by the neurogenic inflammation model.

Ultrasonographic localization of occult pulmonary nodules during video-assisted thoracic surgery

The aim of our study was to evaluate the role of ultrasonography in the localization of pulmonary nodules during video-assisted thoracic surgery (VATS). Ultrasonography was performed in 35 patients for the localization of pulmonary nodules during VATS. Indication for VATS was excisional biopsy of undetermined nodules in 22 patients, single or multiple metastasectomy in 12 patients and resection of primitive pulmonary cancer in 1 patient with reduced pulmonary reserve. A laparoscopic probe with flexible head and multi-frequency transducer (5-7.5 MHz) was used. Intraoperative ultrasonography localized 37 of 40 nodules preoperatively detected by CT and/or by positron emission tomography in 35 patients. Furthermore, ultrasonography localized two nodules not visualized at spiral CT. Eighteen nodules were not visible or palpable at thoracoscopic examination and were found by intraoperative sonography only. In 6 patients in whom thoracotomy was performed, manual palpation did not reveal more lesions than ultrasonography. In our experience, ultrasonography was very helpful when lesions were not visible or palpable during thoracoscopy, showing high sensitivity (92.5%) in finding pulmonary nodules. Since it is not possible to determine preoperatively whether a localization technique will be necessary during the operation or not, and ultrasonography is a non-invasive technique, we think that, at present, this technique can be considered as the first-instance localization technique during thoracoscopic resection of pulmonary nodules.

Glutamate and nitric oxide pathway in chronic daily headache: evidence from cerebrospinal fluid

A central sensitization has been advocated to explain chronic daily headache (CDH) due to sustained peripheral sensitization of allogenic structures responsible for sustained trigeminovascular system activation. Several mechanisms have been suggested to underlie central sensitization, but have been poorly investigated in CDH. They involve N-methyl-D-aspartate (NMDA) receptor activation and nitric oxide (NO) production and supersensitivity and increased and maintained production of sensory neuropeptides. The present study supports the above pathogenic mechanisms demonstrating a significant increase in glutamate and nitrite levels in the CSF of CDH patients, without a significant difference between patients without and those with analgesic overuse headache (P < 0.0001 and P < 0.002). The increase in CSF nitrites was accompanied by a significant rise in the CSF values of cyclic guanosine monophosphate (cGMP) in patients in comparison with controls (P < 0.0001). A statistically significant correlation emerged between visual analogic scale (VAS) values and glutamate, nitrites and cGMP. Although substance P (SP) and calcitonin gene-related peptide (CGRP), and to a lesser extent neurokinin A, were significantly increased in CSF compared with control subjects, their values did not correlate with glutamate, nitrites and cGMP levels in CSF in the patient group. The present study confirms the involvement of glutamate-NO-cGMP-mediated events underlying chronic head pain that could be the target of a new therapeutic approach which should be investigated.

Psychopathology, personality, and marital relationship in patients undergoing in vitro fertilization procedures

OBJECTIVE

To compare the psychopathology, personality features, and marital relationships of women undergoing in vitro fertilization (IVF) with those of control patients, and to compare IVF inductees with program veterans.

DESIGN

Cross-sectional clinical study.

SETTING

A university hospital.

PATIENT(S)

One hundred and one women undergoing IVF treatment.

INTERVENTION(S)

Psychometric tests were administered at first visit (baseline) of index treatment cycle.

MAIN OUTCOME MEASURE(S)

Achievement of pregnancy.

RESULT(S)

Women undergoing IVF show higher levels of anxiety and emotional tension than do controls. Although the infertile women showed no abnormal personality dimensions, the IVF group did have a particular psychological profile and a different marital relationship pattern when compared with the control participants. Between IVF veterans and inductees, there are significant differences with respect to psychopathology, psychological dimensions, and couple dynamics. The achievement of pregnancy is not associated with any special psychopathological, personality, or marital characteristics among the IVF women.

CONCLUSION(S)

The most crucial period in IVF procedures may immediately follow the end of the first cycle because of the high risk of patients dropping out of the program. To determine the most effective supporting therapies for women undergoing fertilization procedures it could be useful to consider the psychological and relational differences between veterans and inductees.

[Lung base disease after orthotopic liver transplantation. Functional ultrasonography of the diaphragm and correlated alterations]

PURPOSE

To demonstrate the greater accuracy of B- and M-probe ultrasound (US) compared to traditional examinations in the evaluation of diseases of the lung-base, a frequent localisation of pathology in patients undergoing orthotopic liver transplantation (OLT).

MATERIAL AND METHODS

Twenty-one patients, 13 males and 8 females aged 24 to 63, awaiting OLT were examined using the three modalities. B-mode US was performed as a preliminary study to identify the districts of interest and the profile of the diaphragm wall, searching for any related alterations. This was followed by M-mode US, with an approach along the left and right posterior axillary lines during spontaneous and forced maximal expiration, to calculate and document the curve representing diaphragm mobility. All patients were also studied pre- and postoperatively by standard chest X-ray double projections. The parameters evaluated by US were diaphragmatic inspiratory slant and diaphragm range while the standard chest X-ray was used to assess hypoventilation, diaphragm range and pleural effusion.

RESULTS

For each parameter considered we obtained the following results: presence or absence of pleural effusion (sensitivity: 100% with US vs 64% with chest X-ray) and diaphragmatic hypomobility with related hypoventilatory phenomena (sensitivity: 85% with US, with 15% false negatives). In 15 cases the chest X-ray revealed a clear elevation of the diaphragm, a finding supported by US in 11 cases. In 7 cases US showed a reduction in the diaphragm range curve without, however, any radiological evidence of any ventilatory dysfunction of the lung base and/or elevation of the corresponding hemidiaphragm.

CONCLUSION

Our results suggest that radiology, B-mode US and color Doppler US, which are widely used for monitoring OLT patients, can be usefully integrated by M-mode US to evaluate diaphragmatic mobility both pre- and post-operatively. This method is fast, easy to use and widely available.

[Intraoperative echography in the localization of pulmonary nodules during video-assisted thoracic surgery]

PURPOSE

One of the major limitations of thoracoscopic resection of lung nodules is localization of the target, especially when the lesion is deep or very small: we investigated the efficacy of US as a technique for intraoperative localization.

MATERIAL AND METHODS

We examined 11 patients who underwent diagnostic and/or curative thoracoscopic resection of benign or malignant, primary or metastatic lung nodules. The study was preceded by a preliminary phase in which we examined with US 5 patients that underwent thoracotomy. A multifrequency laparoscopic US probe with a deflectable linear headpiece mounted on a portable Esaote-Hitachi Spazio US unit was used.

RESULTS

The US exploration of the lung requires the complete collapse of the parenchyma and is therefore particularly difficult in patients with severe chronic obstructive pulmonary disease (COPD). In the patients examined during thoracotomy US showed all the lesions but one 7-mm nodule in an emphysematous patient in whom complete parenchyma collapse could not be achieved. Also in the patients examined during thoracoscopy US detected all the targets (13/13), even a 13-mm metastatic nodule which had been visualized preoperatively by PET only. The smallest lesion found was a 4-mm fibrosarcoma metastasis. The mean time to achieve adequate lung collapse was about 40 minutes from selective exclusion of the affected lung.

DISCUSSION

Thoracoscopic US has been recently introduced for the intraoperative localization of pulmonary nodules. In our experience this technique is helpful in localizing the targets, assessing the extent of surgical resection and studying possible vascular involvement. Considering the easy execution, the low cost, the lack of contraindications and complications of the technique and its accuracy when performed under optimal technical conditions, we think there are enough reasons to investigate this approach further.

CONCLUSIONS

Intraoperative US proved to be a useful technique of easy execution, even though it is heavily operator-dependent and limited in patients with severe COPD.

Uracil/tegafur plus oral calcium folinate in advanced breast cancer

Uracil and tegafur (in a molar ratio of 4:1 [UFT]) has proven activity against breast cancer and is delivered in an easy-to-administer oral formulation. Orzel, which combines UFT with the oral biomodulator, calcium folinate, may provide even greater antitumor efficacy against breast cancer. Here, we describe the preliminary results of this phase II trial investigating the feasibility of 250 mg/m2/day of UFT plus 45 mg/day of oral calcium folinate administered to highly pretreated patients with advanced breast cancer. The results indicate a highly tolerable regimen and an overall response rate of 27.8% in a group of poor-prognosis patients. These findings warrant continued investigation.

A prospective, randomized Phase III trial comparing combination chemotherapy with cyclophosphamide, doxorubicin, and 5-fluorouracil with vinorelbine plus doxorubicin in the treatment of advanced breast carcinoma

BACKGROUND

A prospective, multicenter, randomized, Phase III trial comparing the efficacy of combination chemotherapy with 5-fluorouracil, doxorubicin, and cyclophosphamide (FAC) with a combination of vinorelbine and doxorubicin (NA) in the treatment of patients with advanced breast carcinoma was undertaken.

METHODS

One hundred and seventy-seven patients who previously were untreated for recurrent or metastatic breast carcinoma were entered into the study; 7 patients could not be assessed. The final analysis relates to 85 patients who were treated with FAC and 85 patients who were treated with NA, of whom 21 (25%) and 44 (52%), respectively, had received prior adjuvant chemotherapy.

RESULTS

The overall response rates were similar for the two treatments and were unaffected by prior exposure to adjuvant therapy; overall response rate (ORR) for FAC was 74% (95% confidence interval [95% CI], 65-83%), and the ORR for NA was 75% (95% CI, 66-84%). The activity of NA in patients with liver involvement was greater than that of FAC in terms of survival. Overall survivals were similar, with a median of 17.3 months for patients receiving FAC and 17.8 months for patients receiving NA. Severe toxicity was uncommon with World Health Organization Grade 3-4 neutropenia affecting only 7% of patients in each arm of the study. NA was associated with a higher incidence of mild to moderate constipation, neurotoxicity, and phlebitis, whereas FAC produced a slight excess of mild cardiotoxicity.

CONCLUSIONS

The efficacy of these two regimens is very similar, although NA may be more active in a subset of patients with visceral metastatic disease, particularly liver involvement. It is clear that, in a direct comparison with an established three-drug regimen, the newer two-drug combination of NA demonstrated equivalent activity with no significant excess of Grade 3-4 toxicity.

Screening for colorectal cancer by once only sigmoidoscopy: a feasibility study in Turin, Italy

OBJECTIVES

To assess the impact on compliance of three invitation methods, as well as the acceptability and efficacy of two bowel preparation regimens, for endoscopic screening in the general population.

METHODS

1170 subjects (men and women aged 55 to 59, in the rosters of a sample of general practitioners (GPs) in Turin), were randomly allocated to one of three invitation groups (A: personal letter, signed by GP, with a pre-fixed appointment; B: same as for A + letter supporting the study by a well known scientist; C: letter signed by the study coordinator, NS) and two preparation regimens (i: one enema, self administered at home two hours before the test; ii: two enemas, administered the night before and two hours before the test). A postal reminder was mailed to non-attenders. A sample of non-responders was contacted for a telephone interview by a trained nurse. Written consent was obtained from all subjects undergoing the test.

RESULTS

A total of 278 subjects attended for sigmoidoscopic screening. An invitation from the GP alone produced the highest response rate (compliance: A = 29.3%; B = 24.9%; C = 26.8%). A single enema was as effective as two enemas in achieving satisfactory preparation for the test: the proportion of subjects invited to repeat the test was 8.1% in the single enema group, and 9.6% in the group receiving two enemas.

CONCLUSIONS

Compliance with this screening procedure tends to be low. One enema, self administered two hours before sigmoidoscopy, can ensure a satisfactory bowel preparation.

Effects of maternal weight variations and gestational diabetes mellitus on neonatal birth weight

We evaluated the effects of gestational weight gain on neonatal birthweight women in whom gestational diabetes mellitus (GDM) was diagnosed after the 32nd week of gestation. The prevalence of macrosomia, the birthweight differences from 50th percentile value of a reference population, and the relationships among plasma glucose values during oral glucose tolerance test and neonatal birthweight were evaluated in 60 newborns from mothers with gestational diabetes mellitus divided according to pregravid body-mass index. Serving as controls were 132 newborns of mothers with normal glucose tolerance. The prevalence of macrosomia was higher in the GDM group; the neonatal birthweight difference above 50th percentile value was higher in newborns of mothers with GDM; and a strong relationship between maternal gestational weight gain and neonatal birth weight was present in all pregnant women. In conclusion, (1) the gestational weight gain is a good predictor of neonatal birth weight in all pregnant women; (2) GDM enhances the increase in neonatal size induced by excessive gestational weight gain alone, and (3) a weight gain of more than 9 kg makes the relative risk of macrosomia twofold higher in GDM than in control mothers.

Fistulosphincterotomy in the endoscopic approach to biliary tract diseases

We report our experience with 49 patients who underwent fistulosphincterotomy (FS) after cannulation of the common bile duct (CBD) by standard approaches had failed, due to suspected CBD obstruction. Only 4% of our cases turned out to have no biliary obstruction at all. The morbidity rate was 16%, and the mortality rate was 2%. In our series, FS raised the success rate of CBD cannulation from 90% to 96%. Ninety-five percent of successful cannulations were followed by endoscopic treatment. There were no cases of perforation or hemorrhage, and no difference in the success rate between FS in flat papillas and FS in bulging papillas, thanks, perhaps, to the technique we used. Our findings would indicate that FS is a useful procedure involving additional but not prohibitive risks. Nonetheless, it should be used only when CBD obstruction is strongly suspected and standard methods are not successful.

[Resectoscopic endometrial ablation in the treatment of recurrent, dysfunctional menometrorrhagia: our experience]

Advances in hysteroscopic surgery provide additional options to hysterectomy for the treatment of dysfunctional uterine bleeding resistant to medical therapy and multiple curettages. Two techniques are now available: (a) Resectoscopic endometrial ablation. (b) Electrocoagulation or laser photovaporisation of endometrium. 52 patients underwent resectoscopic endometrial ablation at the Gynaecology Department of Parma University from January 1991 to April 1993. All patients suffered from dysfunctional uterine bleeding without atypical histologic findings on endometrial biopsies and had a normal shaped uterine cavity. 41 patients were subsequently contacted for follow-up. Follow-up period ranged from a minimum of 3 months to a maximum of 24 months. 78.1% of the patients reported a satisfactory outcome (amenorrhea or decreased menstrual flow). No operative complication occurred. Post operative complications included one case of hematometra.

CONCLUSIONS

resectoscopic endometrial ablation is an advantageous technique but our follow-up period is relatively short and long term sequelae have yet to be determined.

[Endoscopic therapy of giant choledochal calculosis]

The paper reports the results of conventional endoscopic treatment in 100 consecutive cases of giant lithiasis of the common bile duct. A giant calculus is one whose dimensions exceed 2 cm. Endoscopic therapy proved successful in 73% of cases, with an 8% incidence of complications. The success of endoscopic treatment is related to the anatomical conditions of the biliary tract and the diameter of calculi. Mechanical lithotripsy has proved efficacious in all cases where it was used, whereas poor results were obtained using MTBE infusion through a naso-biliary tube. ESWL provided encouraging results. Cases which were not resolved using endoscopic methods were treated using intervention radiology or surgery, or both.
