RESUMO

BACKGROUND: Literature concerning the effect of diaphragm treatment to reduce neck pain symptoms is scarce. Aim of this trial was to investigate the effects of diaphragm manual therapy associated with standard physiotherapy treatment on pain in patients with Chronic Neck Pain (CNP). METHODS: In a private practice clinic, subjects with CNP were randomly assigned to receive three 30-min treatment sessions of standard cervical physiotherapy and Diaphragm Manual Therapy (DMT) or Sham Diaphragm Technique (SDT). Participants and assessors were blinded to the assignment. Primary outcome was pain, secondary outcomes were cervical active range of motion, pain pressure threshold, disability and quality of life measured at baseline, before and after each session, at 3 and 6-months. Adverse events were monitored. A non-parametric multivariate approach (combined permutation test) was applied to assess the effect of the treatment on all the outcomes. An intention to treat analysis was performed. RESULTS: Forty patients were randomly allocated to DMT and SDT groups. Combined permutation test showed a significant higher improvement in DMT group compared to SDT group (p-value = 0.0002). The between-group comparisons on single outcomes showed a statistically significant improvement only for pain pressure threshold on upper trapezius (adjusted p-value = 0.029). No adverse events related to the intervention were registered. CONCLUSIONS: In patients with CNP, addition of diaphragm manual techniques to standard cervical treatment seems to give a better global outcome, but this improvement is of unclear clinical relevance; the primary outcome seems not to have a role. Further studies are needed to confirm and clarify these results. TRIAL REGISTRATION: Release Date: July 18, 2017 Registered in ClinicalTrial.gov database ID: NCT03223285A.

RESUMO

Acanthosis nigricans (AN) is a lesion affecting localized areas of the skin in persons with obesity and/or hyperinsulinemia. Biochemical mechanisms responsible for developing this hyperplastic lesion are unclear, but likely involve local cutaneous growth factors. It is associated with obesity, endocrinopathies (insulin resistance, diabetes mellitus, Cushing disease and acromegaly) and visceral malignancies. Clinicians should recognize AN because it may herald disorders ranging from endocrine disturbances to malignancy. Early recognition of these conditions is essential to identify children who are at highest risk for developing type 2 diabetes and further metabolic abnormalities.

RESUMO

The purpose of this mini-review is to present the National Health System and services available for adolescents in Italy, and to review the most relevant data on morbidity and mortality in Italian teens. Adolescent medicine in Italy is not a separate speciality, but there are some distinct services for adolescents in paediatric departments or gynaecologic wards, mostly in large cities where university hospitals or hospital of national relevance are located. Primary health care in Italy is provided mainly by general practitioners (GPs) and pediatricians, and on-call physicians (Guardia Medica) for after-hours medical care and services. The number of centres providing care for adolescents in Italy is 4097 (50% of these are in the North of Italy, 20% in the Central regions and 20% in the South and Islands). The population of Italy on January 1st 2011 was approximately 60,477,881 and the number of adolescents, aged 10 to 19 years, was 6,214,000. The most frequent causes of death in adolescents are motor vehicle accidents - more than half of which are related to drug or alcohol use - followed by cancer and suicide. In primary care, adolescents present with a large number of issues, particularly upper respiratory infections, musculoskeletal problems, pain syndromes, obesity, eating disorders, dermatological issues, mood and somatoform disorders, school and mental health problems, and chronic fatigue, many of which require a coordinated, multidisciplinary management approach. The estimated population with a chronic illness is 8%. There are no specific protocols for the transition to adult medicine physicians for patients with chronic diseases or special health needs. In order to improve the quality and quantity of education in adolescent health for paediatricians and GPs, the Study Group of Emilia and Romagna Region for Adolescent Health Care (SGA-ER) is going to organize, beginning in 2012, a two year educational intervention course in adolescent health.

RESUMO

Adolescent medicine is a field dedicated to helping young people grow and thrive, in relation to their particular stage of development. In Italy, adolescent medicine is not a distinct speciality, but it is practised in some services for adolescents in paediatric departments. Increasing educational opportunities in adolescent health may help to accelerate the development and dissemination of new and improved therapeutic approaches for serving youth and also attract a larger cadre of physicians. Other pediatric subspecialties, e.g. oncology, rheumatology and adolescent psychiatry, have developed successfully and may represent excellent models for adolescent medicine specialists to emulate. The Adolescent Health Study Group of the Emilia and Romagna Region (SGA-ER) was established in 2010 in an effort to generate strategies and possible solutions to improve the quality and quantity of knowledge in adolescent health care for pediatricians and GPs. Several methods and approaches have been implemented to improve physicians' skills in adolescent health care. The authors report the goals, content and instructional design of an educational course in adolescent medicine. Alliances with other adolescent health groups may provide an additional opportunity for networking, interaction and exchange of ideas amongst professionals.

RESUMO

Skeletal dysplasias (SKD) are genetic disorders that result in the abnormal development of part or all of the skeleton and are commonly associated with short stature. The most common SKDs that typically result in short stature include achondroplasia/hypochondroplasia (HCH) both caused by different mutations in the same gene. HCH diagnosis is based on the clinical appearance during development and conventional X-ray findings. In about 70% of patients, missense mutations in the gene coding for the fibroblast Growth Factor Receptor 3 (FGFR3) affects the amino acid at position 540, mostly resulting in the amino acid exchange N540K.Subjects with HCH, heterozygous for the N540K substitution are significantly more disproportionate than individuals without this mutation. We report the clinical and radiographic features of an Italian family with HCH with an unusual N540S mutation, inside the common mutation hot spot of this condition. This is the first case reported in Italy and the third in the literature. During a 7-years-follow-up, the boy started the puberty at the age of 11.3 years and the growth spurt was observed between 13.7 and 14.9 years (+ 9.1 cm.).During pubertal development the sitting height (SDS) improved from - 1.5 to - 0.6 and the subischial leg length (SDS) progressed from - 2.6 to - 3.3.At the age of 16.7 year the standing height was 157.6 cm ( - 2.4 SDS), testicular volume was 15 ml and bone age 16.5 year. The present study and the other two cases reported in the literature stress the important role of the asn 540 site in the tyrosine kinase I domain in the pathogenesis of HCH and underline the importance that, in patients with HCH who do not have the common N540K mutation, sequence analysis of the tyrosine kinase I domain of FGFR3 should be performed to exclude other changes in that region.

RESUMO

Neonatal bacterial meningitis (NM) continues to be a serious disease with an unchanging rate of adverse outcome of 20-60%, despite a worldwide decline in mortality. The 3 major pathogens in developed countries are: Group B streptococcus, gram negative rods and Lysteria monocytogenes. Signs and symptoms of NM may be subtle, unspecific, vague, atypical or absent. In order to exclude NM, all infants with proven or suspected sepsis should undergo lumbar puncture. Positive culture of cerebrospinal fluid may be the only way to diagnose NM and to identify the pathogen, as CSF parameters Smay be normal at early stages and NM may occur frequently (up to 30% of cases) in the absence of bacteraemia. When NM is suspected, treatment must be aggressive, as the goal is to achieve bactericidal concentration of antibiotics and to sterilize CSF as soon as possible. Antibiotics should be administered intravenously, at the highest clinically validated doses. Empiric antibiotic treatment should include agents active against all main pathogens; currently the recommended empiric treatment of NM is ampicillin, plus an aminoglycoside and a third-generation cephalosporn. Therapy should be reassessed after cultures and antibiotic susceptibility is available. Prevention of neonatal sepsis, early recognition of infants at risk, prompt treatment and future adjunctive therapies will improve prognosis. Finally, we present the first preliminary Italian data on GBS meningitis. Data are obtained from an area-based study conducted In Emilia-Romagna during 2003 to 2009.

RESUMO

This study reports the infectious peritonitis rates in 44 patients on peritoneal dialysis in three different systems over the last 15 years, covering clinical outcomes, exit-site infections, tunnel infections, causative microorganisms, and the history of susceptibility of organisms causing peritonitis, in order to establish our center-specific selection of empiric therapy. Two microbiological procedures were herein used: method A, where 100 ml of dialysate were centrifuged and cultured in standard media and into blood-culture bottles; and method B, where 10 ml were directly injected into blood-culture bottles. Swabs from the exit-site or tunnel were taken when purulent drainage was observed. There were 96 episodes of peritonitis during 110.43 patient-years (0.87 episodes/patient-year). Sensitivity of method A was 96.88% (93/96 episodes) versus 81.25% (78/96) of method B (p=0.001). Gram stain sensitivity was 36.46%. The etiologic agents were 64 (56.64%) gram-positive cocci, 22 (19.47%) gram-negative fermentative rods, 20 (17.7%) gram-negative non fermentative rods, 5 (4.43%) yeasts, 1 (0.88%) micelial fungus, and 1 (0.88%) anaerobic rod. Fifty-five exit-site infections were documented (0.5 episodes/patient-year). Ceftazidime and imipenem showed excellent activity on gram-negative rods. There were 92.3% of methicillin-susceptible Staphylococcus aureus but only 33.3% of methicillin-susceptible coagulase-negative staphylococci; vancomycin was active against 100% of the gram-positive cocci. The clinical outcomes of peritonitis were 73 initial cure, 19 catheter removal and four related deaths. The empiric therapy in our center should be vancomycin plus ceftazidime or imipenem. Once the etiological agent and its susceptibility pattern are known, the deescalating therapy must be applied to avoid the emergence and spread of vancomycin-resistant microorganisms.

Se comunican las tasas de peritonitis infecciosa de 44 pacientes en tres sistemas diferentes de diálisis peritoneal durante los últimos 15 años. Se evaluaron evolución clínica, infecciones del sitio de salida y del túnel, y los microorganismos causales y su sensibilidad, a fin de seleccionar la mejor terapia empírica para nuestro centro. Se realizaron dos procedimientos microbiológicos, método A: 100 ml del dializado fueron centrifugados y cultivados por métodos convencionales y en frascos para hemocultivo; método B: 10 ml fueron directamente inoculados en frascos para hemocultivo. Los hisopados del sitio de salida y del túnel fueron realizados cuando se observó supuración. Se registraron 96 episodios de peritonitis en 110,43 paciente-años (0,87 episodios/paciente-año). La sensibilidad del método A fue 96,88% versus 81,25% del método B (p = 0,001). La sensibilidad de la coloración de Gram fue 36,46%. La distribución de los agentes etiológicos fue la siguiente: 64 (56,64%) cocos gram-positivos, 22 (19,47%) bacilos gram-negativos fermentadores, 20 (17,7%) bacilos gram-negativos no fermentadores, 5 (4,43%) levaduras, 1 (0,88%) hongo micelial, 1 (0,88%) bacilo anaerobio. Fueron documentadas 55 infecciones del sitio de salida (0,5 episodios/paciente-año). La ceftazidima y el imipenem mostraron una excelente actividad sobre los bacilos gram-negativos. La sensibilidad a meticilina fue de 92,3% para Staphylococcus aureus y 33,3% para estafilococos coagulasa negativos; la vancomicina fue activa frente al 100% de los cocos gram-positivos. La evolución clínica de las peritonitis fue: 73 curas, 19 remociones de catéter y cuatro muertes relacionadas. La terapia empírica en nuestro centro debería ser vancomicina más ceftazidima o imipenem. Una vez conocidos el agente etiológico y su sensibilidad, se debería aplicar la terapia de desescalonamiento para evitar la emergencia y diseminación de microorganismos resistentes a la vancomicina.

RESUMO

Fungal peritonitis is a rare but serious complication of peritoneal dialysis. The aim of this study was to analyze peritonitis rates, associated factors, clinical course, microbiological aspects, therapeutic regimens, and outcome of patients with fungal peritonitis in the dialysis center of a teaching hospital over the last 25 years. A hundred and eighty three episodes of peritonitis were detected and microbiologically documented in 57 patients. Fungi were identified in eight episodes (4.37%) occurring in seven female patients. The fungal peritonitis rate was 0.06 episodes/patient-year. Gram and Giemsa stains were positive in five out of eight dialysate fluids. The causative microorganisms were: Candida albicans in five episodes, and Candida parapsilosis, Candida glabrata, and Neosartorya hiratsukae in the remaining three. Antibiotics were administered to all but one patient, within 3 months before fungal peritonitis was detected. All patients required hospitalization, and antifungal therapy was administered in all episodes. The Tenckhoff catheter was removed in seven out of eight fungal peritonitis. All patients recovered from the fungal episodes. In the group of patients studied, it is concluded that recent exposure to antibiotics and female sex, were strongly associated with the development of fungal peritonitis by yeasts. The peritonitis caused by the environmental filamentous fungus did not require antibiotic pressure. Direct microscopy of the dialysate pellet was extremely useful for the prompt management of the fungal episode. Fungal peritonitis preceded by multiple episodes of bacterial peritonitis always determined the definitive dropout of the patient from the peritoneal dialysis program. Patients with de novo yeastrelated peritonitis could continue on the program.


La peritonitis fúngica es una complicación infrecuente pero grave de la diálisis peritoneal. Los objetivos de este trabajo fueron el análisis de las tasas de peritonitis, factores asociados, aspectos clínicos y microbiológicos, esquemas terapéuticos y evolución de los pacientes afectados. Se detectaron y documentaron microbiológicamente 183 episodios de peritonitis en 57 pacientes. Se identificaron hongos en ocho episodios (4,37%) en siete pacientes, todos ellos de sexo femenino. La tasa de peritonitis fúngica fue 0,06 episodios/paciente-año. Las coloraciones de Gram y Giemsa revelaron la presencia de microorganismos en cinco de los ocho líquidos de diálisis evaluados. Los microorganismos causales fueron Candida albicans en cinco episodios y Candida parapsilosis, Candida glabrata y Neosartorya hiratsukae en los otros tres. Todos estos pacientes, excepto uno, habían recibido antibióticos en los tres meses previos al episodio de peritonitis fúngica. El catéter de Tenckhoff fue extraído en siete de los ocho episodios. Todos los pacientes evolucionaron favorablemente. Concluimos que en la población estudiada el sexo femenino y la administración reciente de antibióticos estuvieron estrechamente relacionados con el desarrollo de peritonitis fúngicas por levaduras. Sin embargo, la peritonitis causada por el hongo filamentoso ambiental no requirió de la presión antibiótica. La microscopía del sedimento del líquido de diálisis fue útil en el manejo precoz del episodio. La peritonitis fúngica precedida por múltiples episodios de peritonitis bacteriana determinó siempre la exclusión definitiva del paciente del programa de diálisis peritoneal. Los pacientes con peritonitis de novo por levaduras, en cambio, pudieron continuar en él.

RESUMO

We describe an uncommon case of acute leukemia in which leukemic blasts expressed myeloid antigens and cyCD79alpha molecule. In this 49-year old male patient, two distinct blast populations were detected in peripheral blood and bone marrow samples: one of small size resembling lymphoblasts and another with pink cytoplasmic granules resembling myeloblasts. Cytochemical reaction for myeloperoxidase was negative in both cell types. Conventional cytogenetic analysis showed a normal karyotype (46 XY) in all metaphases studied, while gene rearrangement analysis by seminested PCR of the immunoglobulin heavy chain (Ig-H) and T-cell-gamma chain (TCR-gamma) receptor, showed a germline configuration of the TCR and clonal rearrangement of Ig-H chain genes. Multicolour cytofluorimetric analysis showed that bone marrow and peripheral blood blasts expressed CD19, CD79alpha bright, CD22 and terminal deoxynucleotidyl transferase (TdT) as lymphoid markers, CD13, CD117, CD15 as myeloid markers, CD34, HLA-DR as stem cell markers. CD33 myeloid antigen was expressed by 50% of the blastic population. No differences in the immunophenotypic profile were detected in the two blast populations which were identified by morphology. According to EGIL (European Group of Immunological Classification of Leukemias) and WHO (World Health Organization) criteria, a diagnosis of biphenotypic acute leukemia (BAL) was made. The patient was treated with AML induction therapy followed by autologous stem cell transplantation, but relapse free survival was 6 months. The patient died a few weeks later due to unresponsiveness to salvage chemotherapy regimens. We conclude that patients with BAL should have a risk stratification with treatment tailored to their immunophenotype and gene rearrangement profiles.

RESUMO

In the medical literature there are frequently conflicting reports on the utility of biological tumour markers available in the clinical management of breast cancer. In this review we analyse current information on the relationships between the most widely investigated breast cancer biological markers including oestrogen and progesterone receptors, p53, Bcl-2, c-erbB-2, cyclin expression, proliferative activity, DNA ploidy and the urokinase plasminogen activation system, as well as their relevance to prognosis and response to clinical treatment. By biological prognostic indicator, we mean a marker that correlates with survival and disease-free survival; the term predictor marker indicates a marker that is capable of predicting tumour sensitivity or resistance to various therapies. Similarly to other authors' experiences, our analysis suggests that oestrogen receptors are weak prognostic indicators and good predictors of response to endocrine therapy. Furthermore, there are consistent data suggesting that proliferation indices are good indicators of prognosis, and that they are directly related to response to chemotherapy and closely related to response to hormonotherapy. On the contrary, there is no evidence or conflicting data for all of the other biological markers. These should be considered in the context of randomized trials in order to precisely define their prognostic and predictive roles. p53 and c-erbB-2 seem to be the most promising factors, but their use in routine practice still needs validation.

RESUMO

Thirty-seven prepubertal children evaluated for severe growth retardation were studied by assessment of total granulocyte, monocyte and lymphocyte count, lymphocyte subsets CD3+, CD3+Dr+, CD3+Dr-, CD4+, CD8+, CD8+CD57+, CD8+CD57-, CD16+, CD20+ and CD23+, serum immunoglobulin concentrations, and phagocytic activity of circulating neutrophils and monocytes (by a flow cytometric assay). Idiopathic GH deficiency was diagnosed in 21 of 37 patients; the remaining 16 healthy subjects served as controls. Fourteen patients received biosynthetic GH (rhGH), and their immune parameters were assessed at baseline and after 6 months of therapy. Phagocytic function mediated by both polymorphonuclears and monocytes was significantly impaired in GH-deficient subjects compared to controls (p < 0.003 for neutrophils, p < 0.007 for monocytes), while a significant increase of phagocytic activity was obtained during long-term rhGH replacement therapy (p < 0.02 for neutrophils, p < 0.001 for monocytes), thus suggesting that GH may affect the functional activity of circulating phagocyte cells. No significant differences were found in total granulocyte, monocyte and lymphocyte counts, T- and B-lymphocyte subsets and immunoglobulin levels, between GH-deficient patients and controls, and between values observed before and during rhGH substitution treatment.

RESUMO

A retrospective study of 500 consecutive cases of acute renal failure (ARF) in a period covering 1978 through 1991 is presented. A total of 316 females and 182 males with an average age of 46.4 years (14 to 84) had a global survival rate of 68%. Oligoanuric ARF was present in 77% of the patients and, except in 13 cases, all were dialyzed with varied techniques. The treatment plan consisted of early and repetitive dialysis, rational use of antibiotics, and parenteral and/or oral nutritional support. The patients have been divided into three main categories according to etiology: gyneco-obstetric, medical, and postsurgical cases, the latter having the poorest survival rate. With regard to ARF post-septic abortion, we strongly believe that a hysterectomy should not be carried out except in the presence of gangrene or proven uterine perforation, as surgery increases the morbomortality rate in these septic patients.

RESUMO

A case is presented of a prepubertal girl with the characteristic somatic features of Albright's hereditary osteodystrophy, including severe short stature, cataracts and shortening of all metacarpals and metatarsals and of the second middle hand phalanges, whose diagnosis of pseudopseudohypoparathyroidism (PPHP) was confirmed by laboratory evaluation (normocalcemia, normophosphatemia, normal levels of circulating PTH and normal response to exogenous PTH). Since an isolated idiopathic GH deficiency has been diagnosed at the age of 9.7 yr, by an abnormal GH response to standard provocation tests, a poor spontaneous nocturnal GH secretion and a blunted response to GHRH test, our patient was treated with biosynthetic GH during a 3.5-year period. Although a good improvement of growth velocity was obtained when comparing pretreatment height velocity (4 cm/yr) with growth velocity evaluated during GH treatment (6.6, 6.2 and 5.9 cm/yr in the first, the second and the third year of therapy, respectively), bone age advanced more rapidly than chronological age, so that it is uncertain whether the growth acceleration promoted by GH administration really improved final height, which remained below the third centile. Our patient is the first described case of PPHP associated with idiopathic GH deficiency, and the second report of long-term GH treatment in a subject with PPHP. Further observations are necessary to define the frequency and significance of GH deficiency and the role of GH replacement therapy in pseudohypoparathyroidism- and PPHP-associated short stature.
