Robot-assisted Partial Nephrectomy and Bilateral Pyelolithotomy in Ectopic Pelvic Kidneys.

OBJECTIVE: To show how to perform a robot-assisted partial nephrectomy and bilateral pyelolithotomy in ectopic pelvic kidneys. This is a congenital abnormality of position and rotation1 frequently associated with urolithiasis.2 Renal cell carcinoma is a very rare event in pelvic kidneys.3,4 These 2 findings in the same patient could be a surgical challenge and whenever possible a "one stage" treatment is preferred. MATERIALS AND METHODS: A 44-year-old male with bilateral pelvic kidneys admitted because of left back pain. Abdominal CT scan showed a 17 mm stone in the left renal pelvis, a 12 mm stones in the right pelvis and a 34 × 27 mm right lower pole renal mass. A robotic surgery was indicated. Patient was placed in Trendelenburg position with ports configuration as for transperitoneal radical prostatectomy. The right kidney was firstly approached: after isolation of the ureter and suspension of the renal artery, a clampless partial nephrectomy was performed; then through a longitudinal pyelotomy the stone was extracted. To minimize the opening of the posterior peritoneum covering the left kidney, the site of the stone was identified by intraoperative ultrasound; then, through a longitudinal pyelotomy the stone was extracted. Given the watertight sutures and the lack of ureteral obstructions no pigtails ureteral catheters were inserted. A Jackson-Pratt drainage was placed through the inferior port. RESULTS: Consolle time was 190 minutes. Estimated Blood Loss (EBL) was 50 ml. No complications were reported. The drain was removed on the second postoperative day, assessed that creatinine dosage was equal to serum. The length of stay was 4 days. Histopathology showed a pT1a G2 clear cell renal cell carcinoma with negative surgical margins, while stones analysis was calcium oxalate. CONCLUSION: With the availability of robotic technology, the indications for minimally invasive surgery may be safely expanded to include concomitant morbidities in uncommon presentations.

Implications of modified food choices and food-related lifestyles following the economic crisis in the Marche Region of Italy.

BACKGROUND: The economic crisis in Italy has led to profound changes in resource management not only at the macro level but also for individual families, causing substantial changes in different habits of Italians. STUDY DESIGN: The purpose of this research was to conduct a study on changes in family eating habits potentially triggered by the economic crisis was conducted in an area of the Marche Region in central Italy. METHODS: The research was conducted in the period 2016 - 2017 by administering a specific and anonymous questionnaire. RESULTS: The interviewed people has reduced its food consumption. In particular, analyzing the results for the animal protein food group, there has been a reduction in purchase of beef, and an increase in that of pork. Overall fish consumption has decreased by 44%, with a decrease in the purchase of fresh fish, and an increase in that of canned fish products. Finally, consumers have reduced their purchases of fresh and canned legumes, fresh vegetables, and fresh fruit. CONCLUSION: The economic crisis seems to have changed the eating habits and food-related lifestyle choices of the subjects studied, especially in the urban area affected by the deeper economic depression. These changes are likely to have permanent social consequences, and deserve to be analyzed also in smaller territories in order to better understand the dynamics of individual choices and the social framework.

Heat urticaria: a revision of published cases with an update on classification and management.

Heat urticaria (HU) is a rare type of physical inducible urticaria, characterized by itchy erythema and well-demarcated weals appearing soon after heat exposure. Most cases occur in female patients aged 20-45 years. Both localized and generalized forms exist, depending on the limitation of the reaction to the skin area directly exposed to the physical stimulus or the involvement of distant sites, respectively. In most cases, HU is an immediate reaction, but delayed forms (mostly familial) have been described. HU is a long-lasting disease with overall duration at diagnosis of approximately 2 years. In about half of cases it is associated with systemic symptoms such as weakness, wheezing, headache, flushing, nausea, vomiting, diarrhoea, tachycardia, even dyspnoea or syncope. The main differential diagnosis includes cholinergic urticaria, exercise-induced anaphylaxis and solar urticaria. The diagnosis of HU is established by provocation testing, which is also helpful to evaluate the critical temperature threshold. The mean threshold temperature is about 44 °C. A heat desensitization programme can be an effective treatment. Nonsedating H1 antihistamines administered at licensed doses are the mainstay of symptomatic therapy in nearly 60% of patients, but full symptom relief is achieved in only a minority of them. Omalizumab has proven effective in recent case reports.

Preheated autologous serum skin test in localized heat urticaria.

Localized heat urticaria (LHU) is a rare type of physical urticaria, characterized by itching and erythema and well-demarcated weals, appearing within minutes at heat-exposed body sites. Its pathogenesis has not yet been clarified. We report the case of a 46-year-old woman with a generalized form of LHU, which was induced by exposure to warm baths, and consumption of warm food and drinks. Weal reaction was obtained 10 min after application of a metal cylinder heated to 43 °C. Interestingly, only serum previously heated to 56 °C and injected intradermally for autologous serum skin test induced a weal and flare reaction, whereas serum preheated to 45 °C did not induce any reaction. Our patient did not respond to high-dose antihistamines, and refused a heat desensitization programme. Treatment with colchicine 1 mg/day or ciclosporin A 3.5 mg/kg/day for 1 month yielded no improvement. Mild improvement was obtained with intramuscular injection of triamcinolone acetonide 40 mg every 2 weeks for 2 months.

Interstitial granulomatous dermatitis: a distinct entity with characteristic histological and clinical pattern.

BACKGROUND: Interstitial granulomatous dermatitis (IGD) is a rare disease for which a clinical-pathological correlation is essential to establish diagnosis. OBJECTIVES: To describe the histological and clinical features of patients with IGD seen in our department from 2004 to 2010, and to undertake a literature review and critical analysis of additional cases. METHODS: Twelve adult patients (nine women and three men; mean age 58·5 years; range 32-73 years) with IGD were enrolled. Lesions consisted of asymptomatic erythematous papules and plaques, symmetrically distributed on the trunk and the proximal limbs. Two patients had skin-coloured papules. Six patients had articular involvement (arthralgias, spondyloarthritis, rheumatoid arthritis) and three patients had cancer. RESULTS: All cases showed a predominant CD68-positive macrophage infiltrate distributed between collagen bundles of the mid- and deep dermis. Macrophages were also surrounding degenerated collagen fibres. A few neutrophils and/or eosinophils were also present. No vasculitis or significant mucin deposition was observed. Of the 62 cases of IGD reported since 1993, 53 fulfilled stringent diagnostic criteria. Erythematous papules and plaques on the trunk and proximal limbs were the dominant manifestation. Approximately 10% of patients had cord-like lesions. More than 50% of patients with IGD had arthralgia or arthritis, and less commonly other rheumatic disorders. Disease duration is months to years, but long-term prognosis seems favourable. CONCLUSIONS: IGD is a distinct entity with a typical histological and clinical pattern. The importance and the nature of the association with extracutaneous diseases remains to be clarified. Patients should be screened for rheumatic and autoimmune diseases.

Reciprocal modulation of circulating CD4+CD25+bright T cells induced by extracorporeal photochemotherapy in cutaneous T-cell lymphoma and chronic graft-versus-host-disease patients.

The mechanisms of action of extracorporeal photochemotherapy (ECP) in cutaneous T-cell lymphoma (CTCL) are poorly understood. Recently, ECP has been shown to induce an increase in regulatory T cell (Treg) expression and functional activities in Graft-versus-host-disease (GvHD), whereas no data are available in CTCL patients. The aim of this study is to evaluate whether ECP is able to modulate the expression levels of the circulating CD4+CD25+bright subset in CTCL patients and whether these modifications are related to the disease course. The patient population included 43 CTCL and 15 chronic GvHD patients treated by ECP at our institutions since 1992. The expression of the circulating CD4+CD25+bright subset was analysed at baseline and sequentially during treatment by flow-cytometry. Fifty healthy donors were used as controls. The baseline circulating CD4+CD25+bright percentage values in CTCL (median: 4.3 percent) were similar to those of healthy donors, whereas GvHD showed significantly lower values (median: 1.5 percent; p<0.001). During treatment, CTCL patients were characterised by an early decrease (from 4.3 percent to 2.4 percent median after 6 months). The CD4+CD25+bright decrease was associated to the disease course, as it occurred in 91.3 percent of responding but in only 25 percent of PD patients (p=0.0001). On the other hand, a significant increase of CD4+CD25+bright cells was observed in GvHD. ECP induces a reciprocal modulation of the circulating CD4+CD25+bright cells in CTCL and GvHD, with a downregulation in CTCL potentially associated with the response mechanisms.

[Alpha1 adrenoceptors in human urinary tract:expression, distribution and clinical implications].

Adrenergic receptors (ARs) are a class of proteins belonging to the G proteincoupled receptor family. Pharmacological and molecular studies allowed dividing ARs into three different categories: α1, α2 and ß. In this review, we focused on α1 ARs and α1 AR antagonists, since α1 ARs play an important role in the pathophysiology of a number of urinary tract (UT) dysfunctions. α1 ARs are widely expressed in human UT; in particular, the three ureter areas (distal, medial and proximal) show different patterns of receptor expression (i.e. distal > medial = proximal), giving the molecular basis for the use of α1 ARs antagonist in the expulsive therapy of distal ureter calculi. Bladder areas are characterized by important differences among trigone, detrusor and neck, the first showing a different pattern of expression compared to the other parts. Further, there are evidences of both density and subtype gender-dependent expressions. α1 ARs expression in prostate and detrusor is a widely investigated area of research, mainly due to the clinical impact of benign prostatic hyperplasia (BPH). Urethra has not been well studied in human, although it plays a role in the control of continence. Studies carried out on α1 AR subtype expression in the UT indicate that, although the presence of each subtype is observed, α1A firstly and then α1D ARs seem to be more expressed than α1B ARs. Thus, drugs that demonstrate high α1A/D AR selectivity have drawn the researchers' attention. As it relates specifically to the α1 AR antagonists used in the treatment of lower UT symptoms, the concept of uroselectivity has been operationally defined; indeed, in a number of recent publications uroselectivity has been defined as the degree to which a given compound inhibits norepinephrine-induced increase in urinary muscle contractions and/or its propensity to generate unwanted cardiovascular effects, such as decreases in blood pressure.

Avaliação da mecânica ventilatória em indivíduos com disfunção têmporo-mandibular e assintomáticos / Evaluation of ventilatory mechanics in individuals with temporomandibular dysfunction and in asymptomatic individuals

CONTEXTO: A relação entre disfunções respiratórias e têmporo-mandibulares tem sido recentemente constatada pela incidência de dor orofacial entre indivíduos com história de doenças respiratórias obstrutivas tanto de vias aéreas superiores como nas inferiores. OBJETIVO: Avaliar comparativamente a mecânica ventilatória em indivíduos com disfunção têmporo-mandibular (DTM) e em indivíduos assintomáticos. MÉTODO: Participaram do estudo 35 voluntários, sendo 20 indivíduos com DTM e 15 assintomáticos. Os participantes foram avaliados para verificação da presença e grau de disfunção têmporo-mandibular. Realizou-se avaliação respiratória, por meio de inspeção do padrão e tipo ventilatório, medida dos perímetros torácicos, teste de força dos músculos respiratórios e histórico de enfermidade respiratória. RESULTADOS: Nos indivíduos com DTM, o modo respiratório bucal (30 por cento) e misto (15 por cento), bem como o padrão ventilatório apical (45 por cento) foram predominantes. Observou-se uma menor expansibilidade torácica e uma redução estatisticamente significante no índice de amplitude abdominal nos indivíduos com DTM. Estes indivíduos também apresentaram maior incidência de patologias respiratórias obstrutivas tanto de vias aéreas superiores (70 por cento) como inferiores (45 por cento) em relação aos assintomáticos. CONCLUSÃO: Os resultados indicam que existe uma influência da mecânica ventilatória sobre a ocorrência de disfunção têmporo-mandibular.

BACKGROUND: The relationship between respiratory and temporomandibular dysfunctions has recently been brought to light through the incidence of orofacial pain among individuals with a history of obstructive respiratory diseases in the upper and lower airways. OBJECTIVE: To comparatively evaluate the ventilatory mechanics in individuals with temporomandibular dysfunction (TMD) and in asymptomatic individuals. METHOD: Thirty-five volunteers took part in the study: 20 individuals with TMD and 15 asymptomatic individuals. The participants were evaluated to verify the presence and degree of TMD. A respiratory evaluation was carried out by means of inspecting the ventilatory pattern and type, measuring the chest perimeter, testing the respiratory muscle strength and investigating the history of respiratory diseases. RESULTS: The mouth (30 percent) and mixed (15 percent) breathing types and the apical ventilatory pattern (45 percent) predominated in individuals with TMD. There was less chest expandability and a statistically significantly smaller abdominal amplitude index in individuals with TMD. These individuals also presented higher incidence of obstructive respiratory diseases in the upper (70 percent) and lower (45 percent) airways, in relation to the asymptomatic individuals. CONCLUSION: The results indicate that there is an influence from ventilatory mechanics on the occurrence of temporomandibular dysfunction.

T-cell receptor gamma gene rearrangement by multiplex polymerase chain reaction/heteroduplex analysis in patients with cutaneous T-cell lymphoma (mycosis fungoides/Sézary syndrome) and benign inflammatory disease: correlation with clinical, histological and immunophenotypical findings.

BACKGROUND: A dominant T-cell clone can be detected by polymerase chain reaction (PCR) in 40-90% of cutaneous samples from patients with cutaneous T-cell lymphoma (CTCL). MATERIALS AND METHODS: From 1996 to 2003 we analysed 547 cutaneous biopsies performed to exclude CTCL (mycosis fungoides, MF/Sézary syndrome, SS). The final diagnosis was benign inflammatory disease (BID) in 353 samples (64.5%) and CTCL in 194 (35.5%). T-cell receptor (TCR)-gamma gene rearrangement was studied by using a multiplex PCR/heteroduplex (HD) analysis. The PCR results were correlated with the clinical picture, the histological pattern and the presence of T-cell lineage antigen loss, using univariate and multivariate logistic regression analyses. OBJECTIVE: To determine the sensitivity and specificity of the multiplex PCR/HD analysis and to identify which are the clinical, histopathological or immunophenotypical features significantly associated with a positive T-cell clonality. RESULTS: A clonality was demonstrated in 83.5% of CTCL and in 2.3% of BID (P < 0.001). A significantly higher percentage of clonal cases was associated with the cutaneous T-score (71.4% in T1, 76.1% in T2 and 100% in nodular and erythrodermic MF samples) and with the presence of a T-cell lineage antigen loss (93.9% vs. 77.4%). Moreover, clonality was closely related to an increase in the histopathological score (51.3% in the samples with a score < 5, compared with 92% in the lesions with > or = 5). No significant difference in the percentage of clonal cases was found between T1/T2 and T3/T4 lesions with a histopathological score > or = 5. The multivariate logistic regression showed that the density and extent of the cell infiltrate, the degree of epidermotropism and the presence of cytological atypia share an independent predictive value for clonality in T1/T2 samples, even if the highest odds ratios (3.6) were associated with the density of the cell infiltrate. The disease course of T1/T2 patients was analysed according to the PCR findings. All the PCR-negative patients showed a long-standing stable disease course; on the other hand, a disease progression occurred in 12/87 (13.8%) positive patients. CONCLUSIONS: The multiplex PCR/HD analysis is associated with a high diagnostic accuracy (92.7%) in CTCL patients. The finding of a clonal T-cell rearrangement is more closely associated with the histological pattern (in particular with the density and extent of the cell infiltrate) rather than with the MF cutaneous T-score or immunophenotype.

[The patient as a person in the hospital as a business]. / Il malato come persona nell'ospedale azienda.

The ethical and bioethical questions are assuming an increasing importance within the changes that characterize the health field. Nursing, as other professions, examines the relationship between ethics and professional practice. Ethics is often thought of as an element belonging to the real nature of the profession, but it is necessary to know which exigence gives rise to this presumption. The core of all the different ethical conceptions existing to day is always the concept of "the person", that determines different behaviours. To be able to develop ethical responsibilities it is essential to know who the person is.

[Echographic assessment of cutaneous neoplasms]. / Valutazione ecografica delle neoplasie cutanee.

A hundred and fifteen skin tumors were evaluated by means of US. Three variables were considered for each lesion--i.e., borders, echostructure and thickness--and the results compared with histology. High agreement was observed in melanomas: in these tumors, indeed, thickness is well known to be relevant for both surgical planning and prognosis. US scans with a 10 MHz transducer allowed the accurate assessment of borders and structure only in certain, mainly benign, kinds of skin tumors--e.g., angiomas, pilomatrixomas, sebaceous cysts and lipomas--, but also in lymphomas. On the contrary, most malignant neoplasms exhibit hypoechoic structure and borders from clear-cut to blurred. Finally, US proved to be highly reliable in demonstrating lesion thickness before surgery. High agreement was once again observed with histology relative to this variable: thickness (in mm) was the same in 30% of cases, overestimated by US (mean: 0.3 mm) in 44% of cases and underestimated by US (mean: 0.15 mm) in 26% of cases. Particularly, in 41 melanomas, histology-US agreement rate was 44% for the Breslow index, with r = 0.95 and 88% for the Clark index.

Effects of hydroxychloroquine on 'band test' in discoid lupus erythematosus.

Ten cases of localized and generalized discoid lupus erythematosus are reported in which previously untreated patients were given hydroxychloroquine sulphate 600 mg daily for 10 days followed by 400 mg for 20 days. The purpose of the study was to evaluate the effect of this drug on the 'lupus band' before and after treatment, in diseased, unaffected sun-exposed, and unaffected non sun-exposed skin. A good response from both the clinical and immunopathologic (i.e. reduction or disappearance of the immune reactants) standpoint was evident in 6/10 patients; in another 3 patients a good clinical but not immunopathologic response was recorded, while in 1 case a clinical worsening corresponded to an immunofluorescence improvement. In 5/10 cases (4 females, 1 male) one or more immunoglobulin classes which were present in the 'lupus band' before therapy remained at the dermoepidermal junction after treatment.
