Digital subtraction arthrography of the prosthetic hip

Digital subtraction techniques are easily adapted to the evaluation of loosening in total hip prostheses, allowing real time review of injection dynamics and data manipulation after the study. We have successfully used both standard radiographic and digital imaging techniques in the evaluation of 15 prosthetic hip joints. The digital results are comparable to and often better than those of standard radiographic techniques for the evaluation of loosening in total hip prostheses.     

Primary structure and functional expression of a cDNA encoding the thiazide-sensitive, electroneutral sodium-chloride cotransporter.

Electroneutral Na+:Cl- cotransport systems are involved in a number of important physiological processes including salt absorption and secretion by epithelia and cell volume regulation. One group of Na+:Cl- cotransporters is specifically inhibited by the benzothiadiazine (thiazide) class of diuretic agents and can be distinguished from Na+:K+:2Cl- cotransporters based on a lack of K+ requirement and insensitivity to sulfamoylbenzoic acid diruetics like bumetanide. We report here the isolation of a cDNA encoding a thiazide-sensitive, electroneutral sodium-chloride cotransporter from the winter flounder urinary bladder using an expression cloning strategy. The pharmacological and kinetic characteristics of the cloned cotransporter are consistent with the properties of native thiazide-sensitive sodium-chloride cotransporters in teleost urinary bladder and mammalian renal distal tubule epithelia. The nucleotide sequence predicts a protein of 1023 amino acids (112 kDa) with 12 putative membrane-spanning regions, which is not related to other previously cloned sodium or chloride transporters. Northern hybridization shows two different gene products: a 3.7-kb mRNA localized only to the urinary bladder and a 3.0-kb mRNA present in several non-bladder/kidney tissues.     

A therapy impact questionnaire for quality-of-life assessment in advanced cancer research.

The first part of the validation procedure used for a Therapy Impact Questionnaire (TIQ) on quality-of-life assessment in advanced cancer patients is described. The TIQ is composed of 36 items which assess both disease and therapy impact according to four dimensions that operationally define quality of life: physical symptoms (24 items), functional status (3 items), concomitant emotional and cognitive factors (6 items) and social interaction (2 items). A global judgement expressed as "have you been feeling ill" further completes the TIQ. Patients answered each question using a 4-point verbal Likert scale: not at all, slight, a lot and very much. The TIQ was given to 1,000 consecutive patients who were no longer responsive to cancer treatment and presented symptoms due to disease progression. The compliance rate was quite high (87%). Results of confirmatory factor analysis were consistent with the operational dimensions identified during questionnaire construction. In particular, the dichotomized answers to 3 functional status items could be used as a Guttman scale. In a sub-sample of 50 patients, the reproducibility of functional status items was assessed using a 7-item parallel form. The intraclass correlation coefficient obtained indicated a reasonably high reproducibility. On the basis of the analyses conducted, the TIQ appears to be a reliable and concise instrument for studies aimed to assess the effectiveness of therapies in advanced cancer patients.     

Psychosocial adjustment of patients surgically treated for head and neck cancer.

Sixty-six patients, surgically treated for head and neck cancer and free of disease, were interviewed at the outpatient clinic from 6 months to 8 years after surgery. The patients were divided by the physician into two groups, according to the patients' degree of disfigurement, i.e., minor (24 patients, 36%, minor disfigurement group = MDG) or extensive (42 patients, 64%, extensive disfigurement group = EDG). Subsequently, the patients were interviewed with close-ended questions. The following subjective aspects were assessed: self-image; relationship with the partner, family, and friends; and the overall impact of the therapy. The results of the study showed a significantly higher impact in the EDG versus the MDG as regards a changed self-image (57% vs 25%, P less than 0.05), a worsened relationship with the partner (27% vs 0%, P less than 0.05), a reduced sexuality (74% vs 39%, P less than 0.01), and an increased social isolation (36% vs 12%, P less than 0.05). On the whole, 18% of the subjects stated that the disadvantages of therapy outweighed the advantages, and 30% fell that the difficulties encountered were "too harsh." In such cases, the opportunity of setting up a rehabilitation program offering psychosocial support should be considered.     

Extraperitoneal kidney transplantation: a comparison between children weighting ≤15 kg and >15 kg. Experience of a single institution

Extraperitoneal approach is sometimes recommended for kidney transplantation (KT) in children weighting <15 kg. We hypothesized that this approach might be as successful as in patients with normal weight. Data of all consecutive KTs performed between 2013 and 2019 were retrospectively reviewed. Early outcomes and surgical complications were compared between children weighing ≤15 kg (low-weight (LW) group) and those weighing >15 kg (Normal-weight (NW) group). All the 108 KTs were performed through an extraperitoneal approach. The LW group included 31 patients (mean age 3.5 ± 1.4 years), whose mean weight was 11.1 ± 2.0 kg. In the LW group,—a primary graft nonfunction (PNGF) occurred in one patient (3.2%), surgical complications occurred in nine (29%), with four venous thrombosis. In the NW group, PNGF occurred in one case (1.3%), delayed graft function (DGF) in eight (10%), surgical complications in 11 (14%) with only one case of venous thrombosis. In both groups, no need for patch during wound closure and no wound dehiscence were reported. The extraperitoneal approach can be effectively used in LW children. No differences were observed in the overall complication rate (P = 0.10), except for the occurrence of venous thrombosis (P = 0.02). This might be related to patients’ characteristics of the LW group.

Comparison of home and hospital care of advanced cancer patients

Treatment and care of terminal cancer patients are conducted in different ways, according to the cultural, social, political and economical situations of the countries which have progressively adopted and developed them. In Italy there are no specialized structures such as "hospices" or the "palliative care units" like in the Anglo-Saxon world: the care of terminal cancer patients is carried out either in a general hospital or at their own home. In Milan and elsewhere there are home care teams in which doctors, nurses, social workers and volunteers, all work in connection with hospital structures. In this way, patients can receive specialized care for physical, psychological and social problems at home too. To evaluate costs and effectiveness of this program, a comparison was made between the home care and the conventional treatment carried out in general hospitals. Two groups of thirty terminal cancer patients have been studied: the first group was composed of hospital patients in Desio and the second one included patients cared for by the home care service organized by the Floriani Foundation and the Italian League against Cancer (Milan Section). We evaluated intensity and duration of pain, hours of sleep and hours of standing, sitting and lying, presence of side-effects, performance status and therapies. Data were also collected on the quality of life (Spitzer QLI), social and economical needs of the patients, type and quality of care, degree of awareness of the diagnosis by the patient and the family. This data were collected by the nurse who looked after the patient. Care costs were also quantified. The comparison between the two groups significantly favours the home care group as shown by the performance status after 2 weeks of care, the "health scale" and the Total index of the Spitzer QLI and in general the greater satisfaction of the care received. Home care produces results equivalent to those achieved in hospitals as far as clinical parameters are concerned. An approximate quantification of the costs shows that an average cost for a day's home care was about Lit. 52,500 as compared with Lit. 360,000 for a day's hospitalization.     

Meta-analysis of six clinical phase III studies comparing lomefloxacin 0.3% eye drops twice daily to five standard antibiotics in patients with acute bacterial conjunctivitis

· Background: Lomefloxacin 0.3% ophthalmic solution twice daily has been compared in patients with bacterial conjunctivitis in six randomized double-blind or investigator-masked phase III studies with either chloramphenicol 0.5% 5×/day, gentamicin 0.3% 4×/day, fusidic acid 1% 2×/day, tobramycin 0.3% 4×/day or norfloxacin 0.3% 4×/day. · Methods: A meta-analysis of all individual data of these six studies was performed. A total of 582 patients with clinically diagnosed bacterial conjunctivitis were evaluated by slit-lamp examination with grading of eight key signs and symptoms and by conjunctival swab cultures at baseline, on day 3–5 and on day 7–9. Success of therapy, local tolerance and safety were evaluated at termination. In vitro sensitivity of the ocular isolates to 6–10 antibiotics was evaluated by disk diffusion tests. · Results: Two hundred and ninety patients treated with lomefloxacin 0.3% (LF) and 292 patients treated by one of the control antibiotics (combined control group, CCG) were enrolled in the studies. Two hundred and seventy-eight LF and 283 CCG patients were evaluable for the intent-to-treat (ITT) analysis, while 85 LF and 95 CCG patients had bacteria above the pathological threshold and formed the core subpopulation. The mean cumulative sum score in the LF group was 9.47 on day 1, and decreased by 5.70 on day 3–5 and by 8.10 on day 7–9. In the CCG it decreased significantly less: it was 9.19 at baseline, decreased by 5.15 on day 3–5 and by 7.33 on day 7–9. Swab counts decreased in the LF and CCG group similarly, with the major decrease observed between day 1 and day 3–5. Most of the organisms considered resistant in vitro were still eradicated with the regimen used. Of the few surviving organisms also isolated on the next follow-up visit, one isolate in the LF group and seven in the CCG showed decreased in vitro sensitivity towards the treatment antibiotic used. Local tolerance was good or excellent, without any significant differences except for burning sensation, which lasted significantly longer in the CCG group than in the LF group. Adverse events were observed in 18 LF and 23 CCG patients; four LF and three CCG patients had to be withdrawn. All adverse events were non-serious. · Conclusion: Lomefloxacin eye drops used with a loading dosage followed by a twice daily regimen proved as effective, safe and well tolerated as five established standard treatments used at a 2, 4 or 5 times daily regimen, caused less discomfort upon instillation, and showed a lower risk to generate or select new resistant strains.
