RESUMO

PURPOSE: The aim of this study was to evaluate the 5-year recurrence rate of pilonidal sinus disease (PSD) after endoscopic sinusectomy and identify risk factors for recurrence. METHODS: All consecutive patients from September 2011 through December 2017 who underwent endoscopic sinusectomy at seven referral centres for pilonidal sinus treatment were retrospectively analysed from a prospectively maintained database. RESULTS: Out of 290 patients (185 males versus 105 female, with a mean age of 25.5±6.9), 73 presented recurrence at 5-year follow-up with a recurrence rate of 25.2%. The number of pilonidal sinus with pits off the midline (p = 0.001) and the mean (SD) distance from the most lateral orifice to the midline (p = 0.001) were higher in the group of patients with recurrence at 5-year follow-up. Multivariate analysis demonstrated that the position of the pits off the midline (p = 0.001) and the distance of the most lateral orifice from the midline (p = 0.001) were independent risk factors for recurrence at 5-year follow-up. Receiver operating characteristic (ROC) curve analysis showed that the distance of lateral orifice from midline predicted an 82.2% possibility of recurrence at 5-year follow-up and Youden's test identified the best cut-off as 2 cm for this variable. Out of 195 cases with the most lateral orifice less than 2 cm from the midline, 13 presented recurrence at 5-year follow-up with a recurrence rate of 6.7%. Out of 95 cases with the most lateral orifice more than 2 cm from midline, 60 showed recurrence at 5-year follow-up with a recurrence rate of 63.2%. CONCLUSIONS: This data may help guide which disease characteristics predict the optimal use of an endoscopic pilonidal sinus technique.

RESUMO

Acne, once considered as a mere esthetic problem, is now recognized as a disease that can cause major disturbances of the psychological and emotional sphere. Currently, the treatment of acne is focused on one or more pathogenic factors: hormonal stimulation and sebaceous hypersecretion, disorder of keratinization, colonization of Propionibacterium acnes and inflammation. The aim of the paper was to evaluate the use of inositol in patients with moderate acne.

RESUMO

This pilot open-label study is aimed to assess clinical response in psoriasis patients receiving diverse dose regimens of etanercept, consisting of the same global cumulative dose of etanercept administered over different treatment periods. Eligible patients were assigned sequentially in a 1:1 ratio to receive: etanercept 50 mg once weekly (QW) or 50 mg twice weekly (BIW) for 12 weeks. The final analysis included a total of 72 patients. At week 12 the Psoriasis Area and Severity Index (PASI) and Skindex-29 scores notably improved in both treatment arms, without significant differences between the two groups. The rate of patients attaining a PASI improvement >or= 50% (PASI 50) at week 12 was 92% in the high-dose group. In these patients, etanercept dosage was decreased to 50 mg QW from week 13, with persistence of the PASI 50 response at week 24 in all cases. Thereafter, treatment was discontinued up to week 36 and almost 30 % of patients experienced a gradual relapse of their psoriasis within this period. In the low-dose group, the PASI 50 response was observed in 75% of patients. These responders continued to be treated with etanercept 50 mg QW up to week 36 with persistence of the PASI 50 in 100% of cases at week 24 and 93% at week 36. In the low-dose regimen, 8 patients who did not respond at week 12 underwent dose escalation to 50 mg BIW for a further 12 weeks. At week 24, six of these patients gained the PASI 50 response, 4 of whom maintained the response up to week 36, after treatment discontinuation from week 24. Our results confirm that etanercept is very effective and well-tolerated in psoriasis and that the drug dosages and treatment duration may be modulated and adapted to clinical needs in a flexible way.

RESUMO

Rheumatoid arthritis, ankylosing spondylitis and psoriatic arthritis are commonly thought of as inflammatory diseases that affect younger individuals. Although the initial presentation of these diseases is common in a patients twenties or thirties, they usually persist for the duration of the patients life. In addition, up to one-third of patients with RA have disease onset after 60 years of age. Anti-TNF-a therapies now have well-recognized safety profiles that have been demonstrated in the usual clinical trial populations for these diseases, but such populations under-represent patients > or =65 years of age. This retrospective study aims to determine the safety profiles for etanercept, infliximab and adalimumab in patients of 65 years or more, undergoing anti-TNF treatment for an active inflammatory disease such as rheumatoid arthritis, ankylosing spondylitis or psoriatic arthritis, or skin disease like psoriasis. Our data show that admitting elderly patients into anti-TNF therapeutic regimens is a safe option and that it grants these patients access to the best current therapeutic option, possibly leading to better disease outcome. Quality of life in elderly patients affected by arthritis or psoriasis, often reduced by comorbidities, is as important as quality of life in younger patients. Applying the recommended screening before using biological treatment helps to reduce adverse events related to the therapy, and the application of the same screening in elderly patients seems to lead to comparable results.

RESUMO

Psoriatic arthritis (PsA) is a chronic inflammatory disease of the skin and joints characterized by extensive intra-articular bone resorption and silver-red scaly plaques most commonly found on extensor surfaces of the skin. When this arthritis affects the temporomandibular joint (TMJ) and does not successfully halt in its early degenerative process, patients may undergo invasive joint reconstruction that irreversibly changes the TMJ physiologic joint dynamics. This study presents a case of TMJ PsA: anterior open bite, limited range of motion, and erythematous desquamative plaques of the upper limb extensors surfaces. The patient previously received non-steroidal anti-inflammatory drugs, immunosuppressors, and corticosteroids over a four-year period while suffering the idiosyncratic drug side effects from long-term therapy without improvement in joint function or rash resolution. The treatment team then chose etanercept, a synthetic fusion protein therapy that binds with tumor necrosis factor (TNF)-alpha, to interrupt reactive inflammatory arthritis. The patient received the TNF-alpha inhibitor monthly for two years. This last treatment led to full remission of both joint symptomatology and skin lesions. Our results should encourage general dental practitioners' involvement in curing patients with psoriatic arthritis when it affects the TMJ.

RESUMO

There is much evidence to show the efficacy of adalimumab, a human monoclonal antibody targeting tumour necrosis factor-alpha, in the treatment of plaque psoriasis. In this open-label experience, 147 high-need patients suffering from plaque psoriasis, with a mean Psoriasis Area and Severity Index (PASI) of 18.8, and concomitant psoriatic arthritis (PsA) received subcutaneous injections of 40 mg of adalimumab every other week (EOW). This was actually the dosage regimen recommended for PsA, as the drug had not then been approved for psoriasis at the time of the patients enrolment. At week 12, an improvement of at least 50 percent of the PASI (PASI-50) was observed in 111 (77 percent) patients. Continuation of treatment in responders with adalimumab 40 mg EOW led to a sustained response, with the PASI-50 achieved by 97 percent of patients in the as-treated analysis at week 24 (PASI-75 in 82 percent and PASI-90 in 45 percent out of 109 patients who received EOW injections up to week 24). Thirty subjects who failed to attain the PASI-50 response at week 12 were treated with adalimumab 40 mg every week for a further 12 weeks. At week 24, 80 percent of these patients obtained a PASI-50 response after dose escalation. Tolerability was good in the majority of patients. Only two patients discontinued treatment because of an adverse event (repeated flu-like episodes and a pleuropericarditis of unknown origin, respectively).

RESUMO

Infliximab is an anti-tumour necrosis factor-alpha chimeric monoclonal antibody which is highly effective in psoriasis, as well as in other indications. In clinical practice, some patients may require dose escalation to overcome a reduction of the extent and/or duration of response during regular maintenance treatment, possibly due to the loss of stable serum concentrations of the drug. Common strategies of dose escalation are the increase of dose per infusion and the decrease of interval between infusions. Here we report the results of re-induction therapy with infliximab used as a dose escalation strategy in 9 patients whose psoriasis relapsed during maintenance treatment with infliximab 5 mg/kg every 8 weeks. Re-induction was well tolerated and capable of restoring response in 8 of these patients.

RESUMO

We described a case report of a 36-year-old woman with a 10-year-history of idiopathic CD4+ T-lymphocitopenia and Kaposi's sarcoma HHV8+ who developed recurrent pleural effusion. Laboratory and instrumental tests with morphologic, immunophenotypic and molecular analysis of pleural sediment suggest us the diagnosis of primary effusion lymphoma (PEL). The term primary effusion lymphoma defines an extranodal non-Hodgkin's lymphoma HHV8-related, usually classified as a B-cell lymphoma, that grows in liquid-phase within body cavities. The case reported by the Authors appears to be of great interest for its epidemiological and clinical features.

RESUMO

Etanercept is a soluble tumour necrosis factor receptor fusion protein which is approved for the treatment of plaque psoriasis at the dose of either 25mg twice weekly (BIW) or, for the initial 12 weeks, 50mg BIW. Alternative dosing regimens have not been evaluated in psoriasis. In this study, we compare the efficacy and tolerability of two etanercept dosing regimens--50mg BIW and 100mg once weekly (OW)--for 12 weeks in 108 patients with moderate-to-severe recalcitrant psoriasis. Efficacy measures included Psoriasis Area and Severity Index (PASI), severity of pruritus recorded on a visual analogue scale (VAS) and the influence on quality of life assessed by means of Dermatology Life Quality Index (DLQI). Both etanercept regimens caused a significant change in all the efficacy parameters after 4 weeks and 12 weeks, at a comparable rate. At week 12, a PASI improvement of at least 50% from baseline (PASI 50) was achieved by 74% of patients treated with 50mg BIW and 78% of patients treated with 100mg OW. A PASI 75 response was obtained in 54% and 50% of patients treated with 50mg BIW and 100mg OW, respectively. Treatment was well tolerated with similar type and frequency of adverse events between the two groups.

RESUMO

Psoriasis is primarily an inherited inflammatory skin disease, it is characterized by erythemato-squamous lesions that usually involve elbows, knees and the scalp. Oral manifestations are rare in psoriasis, infact, oral psoriasis involves 2% of psoriatic patients and usually it is observed with the onset of cutaneous lesions and progresses with them. Differential diagnosis should be done for Reiter's syndrome, leukoplakia and geographic tongue. The authors describe a case of tongue psoriasis without cutaneous lesions.

RESUMO

The aim of the paper was to describe an unusual case of non lactic metabolic acidosis connected to hypophosphatemia and refractory to infusion of bicarbonate. A 37 year old man was admitted to Intensive Care Unit with a severe metabolic acidosis. On admission the arterial gas analysis showed non lactic metabolic acidosis (pH 7.17; base excess [BE] -20.3; lactic acid 0.8 mMol/L), with hypoxemia and critical hypocapnia. Despite therapy with bicarbonate the acidosis persisted. After 4 hours glucose phosphate was administered, although the phosphoremia was unknown. After phosphate supplementation an improvement of acidosis was observed. Our hypothesis is that in the kidney phosphate depletion caused impaired tubular reabsorption of bicarbonate, which led to a non lactic metabolic acidosis.

RESUMO

The growing incidence of infections due to Gram-positive multiresistant germs has stimulated research into new drugs endowed with broader activity, that are useful in case of infections unresponsive to common antibiotics. The case of a 28-year-old man infected with a methicillin resistant Staphylococcus aureus non responder to therapy with glycopeptide antibiotics is reported. At admission the patient presented a septic condition and required mechanical ventilation. Antibiotic therapy was immediately started with teicoplanin+meropenem. Blood culture and bronchial aspirate evidenced a methicillin resistant Staphylococcus aureus with high sensibility to glycopeptide antibiotics. Although this therapy produced a slight improvement in clinical condition and the patient was extubated, fever and leucocytosis associated with a BAL positive to methicillin resistant Staphylococcus aureus, in vitro susceptible to glycopeptides, persisted. Considering the possibility of a non-responder condition of the patient to glycopeptide antibiotics, quinupristin/dalfopristin was added. The streptogramin produced a quick improvement in clinical condition with resolution of sepsis and culture sterilization. The patient improved progressively and was discharged. In conclusion, in our experience the association quinupristin/dalfopristin was effective in the resolution of a critical methicillin resistant Staphylococcus aureus infection non responder to classical treatment with glycopeptide antibiotics that showed a high sensibility in vitro.

RESUMO

Neurofibromatosis type 1 (NF1) is a common autosomal dominant disease. The Lisch nodule represents one of the most common NF1 ocular manifestations. Several studies have reported that the Lisch nodule is a melanocytic hamartoma but its pathogenesis is still debated. We have studied the histopathological and ultrastructural features of a Lisch nodule of a 50-year-old woman biopsied during an intracapsular cataract extraction. Our researches revealed that it was composed of three main cytotypes: pigmented cells, fibroblast-like cells and mast cells, showing a pattern similar to a neurofibroma. Furthermore, we hypothesize that Lisch nodules are compatible with neurofibromas.

RESUMO

Rhabdomyolysis is a disorder characterized by skeletal muscle injury and fatal complications at times. The causes of rhabdomyolysis are usually traumatic and non-traumatic, such as neuroleptic malignant syndrome and rhabdomyolysis associated to septicemia. The cases of 2 schizophrenic patients with rhabdomyolisis during pneumonia infection and neuroleptic therapy are reported. At admission, both patients had important respiratory distress and hyperthermia; the clinical conditions required endotracheal intubation. Blood and urine cultures were always negative, while the bronchial sputum culture was positive. The diagnosis of rhabdomyolysis was confirmed by myoglobinemia dosage and ortholuidine test. Pneumonia infection was treated with antibiotic specific therapy whereas renal failure was treated with adequate hydratation and strained diuresis. The absence of muscle rigidity, the improvement of X-r images and the reduction of corporeal temperature, during antibiotic treatment, excluded neuroleptic malignant syndrome. The impro-vement allowed extubation and discharge of the patients from intensive care unit. In both cases neuroleptic malignant syndrome was excluded, therefore rhabdomyolysis was the consequence of pneumonia infection or of a combination of factors capable to cause an important damage of skeletal muscles.

RESUMO

BACKGROUND AND OBJECTIVE: It has recently been suggested that recruitment proceeds far above the lower inflection point of the elastic pressure-volume (Pel/V) curve of the respiratory system. Accordingly, the value of the lower inflection point as a guide to set the positive end-expiratory pressure (PEEP) has been challenged. Our aim was to evaluate the derecruitment induced by stepwise decreasing PEEP levels. METHODS: Seven consecutive sedated and paralysed patients with acute respiratory distress syndrome were studied. Multiple Pel/V curves of the respiratory system were recorded at PEEP levels progressively decreasing in steps of 3.75 cmH2O from + 15 to zero according to the principles of the low flow inflation method. RESULTS: Multiple Pel/V curves shifted towards lower volumes at decreasing PEEP. Dynamic compliance was higher for Pel/V curves recorded from lower PEEP levels. A high correlation (r = 0.99) was found between dynamic compliance and PEEP. The lower inflection point was on average 9.2 cmH2O. However, the transition between the lower segment and the linear part of the Pel/V curve was in general smooth to the eye. The upper inflection point was on average 23.8 cmH2O. A high correlation (r = 0.98) between the upper inflection point and PEEP was found. CONCLUSIONS: The lower inflection point is a poor indicator of alveolar closure. The evaluation of derecruitment induced by a stepwise reduction in PEEP seems to be more useful than individual titration of PEEP and tidal volume in patients with adult respiratory distress syndrome.

RESUMO

Concentrations of polycyclic aromatic hydrocarbons (PAH) in atmospheric particulates have been determined in the frame of the control activities for environmental protection during the VI (1990-1991), VII (1991-1992) and VIII (1992-1993) Italian expeditions in Antarctica. Samples were collected at the four cardinal points at about 200 m from the central area of the Italian scientific base. Data show low levels of the individual PAH (95% in the range 1-50 pg m(-3)) confirming the absence, up to now, of significant contamination from the base. These results could be used as a reference for the assessment of the air pollution due to combustion sources present in the base. Any possible variation in the base's activities in the future should be analysed and evaluated with respect to these findings.

RESUMO

Phosphorus plays an essential role in cellular metabolism, especially in the oxidative phosphorylation process and in the synthesis of 2-3 DPG and membrane phospholipids. Moreover phosphorus is necessary as a buffer, mainly when the organism's principal buffer, the H2CO3/HCO3- system, is working at maximal rate. The authors describe a case of severe hypophosphatemia in a ICU patient with a mixed disorder of the acid-base balance. C.P., a woman, aged 71, obese (IBW 145%), at admission in ICU showed increasing dyspnea, hypoxemia and acidosis. Besides alkaline drugs a Venturi mask with FiO2 = 0.3 alternated to CPAP cycles (7 cm H2O) with facial mask applied. Bading on CVP, MAP and ABG results, a pharmacologic therapy with enoximone, furosemide, bronchodilators, mucolytics, antacids, antibiotics and inotropics was performed. TPN with only essential amino acids was performed, in order to activate lipolysis and ketogenesis; but the ABG showed over again mixed disorder of acid-base balance (metabolic and chronic respiratory acidosis), only partially leading to ketogenesis. The reduction of the hematic HCO3-, without changes of PaCO2, was justified by the blood lactic acid of 6.2 mmol/L. And what about blood lactic acid increase? During patient hospitalization, the hematic phosphorus had decreased to, 0.8 mg/dl. Diuretic therapy together with acidosis tamponage, and reduced phosphorus feed had been responsible of severe hypo-phosphatemia. Therapy adjustments brought the phosphatemia to normal values and to a substantial improvement of clinical conditions.

RESUMO

Malnutrition is reported in a significant percentage of COPD patients, and it may contribute to the onset of acute respiratory failure. Weight loss is due to the decrease of caloric support caused by breathlessness, digestive alterations due to hypoxemia and to the increase of energy expenditures caused by increased baseline requirements and diet induced thermogenesis (DIT). Malnutrition limits the ability to produce surfactant, leads to reduced protein synthesis, reduces cell mediated immune responses raising the patient's susceptibility to lung infection and affects the functioning of peripheral and respiratory muscles. The combination of malnutrition and COPD has devastating effects. Nutritional support is, therefore, an important part of therapy for the stable COPD outpatients, for hospital COPD patients and for ICU COPD patients. The nutritional program should follow an assessment of the nutritional status. With a correct number of calories and a correct composition of nutrients, it is possible to help these patients in the different clinical stages of the disease.

RESUMO

The authors describe a clinical case of Multiple Organ Failure (MOF). Such a pathology was reported, at admission in ICU, in a young woman aged 26 who was in the 30th week of amenorrhoea, formerly hospitalized in Obstetrics, where she had had a Caesarean section because of the met of eclamptic crisis, after a pregnancy substantially normal. At the moment of her admission to the ICU the examination highlighted the sense organ obnubilated, the breath dyspnoic, a systolic and diastolic hypotension and a tachycardia of medium seriousness. From laboratory examinations it was possible to maintain that there was a serious anemia with white cells raised, a coagulative imbalance and above all a serious alteration of hepatic and pancreatic function. The creatininemia had increased a bit, a clear contraction of diuresis was present and a considerable metabolic acidosis had become intelled. Therefore the patient was affected by multiple organ failure. In successive days it was possible to execute an EEG that proved substantially normal, then a Computer Tomography to abdomen showed the presence of vast areas of hepatic necrosis, ascitic hemorrhagic fluid and a volume increased pancreas. Hepatitis markers proved negative, while a positive response was achieved for a typhoid infection (this result was reconfirmed many times later.) Modifying the antibiotic therapy (substituting full dose ampicillin to the cephalosporin) the clinical case was solved. Moreover, also thanks to a very good answer to antibiotic therapy, it was possible to confirm the diagnosis of typhoid fever, not gestosis.
