Health-related quality of life and pressure ulceration assessment in patients treated in the community

Little is known of the impact of pressure ulceration on adult patients' health-related quality of life. The purpose of this study was to determine the impact pressure ulceration has on pressure ulcer patients cared for in the community. A case control study design was used by drawing a random sample from patients receiving community nursing care, stratified by the presence of pressure ulceration. In all, 75 patients with pressure ulcers were compared with 100 controls without ulcers using the four-point ulcer grading scale described by United Kingdom consensus guidelines. Patients were interviewed using the Short Form-36 (SF-36) questionnaire and activities of daily living assessed using the modified Barthel scale. Patients with pressure ulcers had significantly poorer physical function (mean difference (d) = 37.6, 95% CI 28.6-46.6, p < 0.001) and social functioning (d = 33.9, 95 % CI 24.0-43.9, p < 0.001) than published age- and sex-matched normative data from the United Kingdom. The difference between cases and controls was much smaller in these domains, with neither approaching statistical significance. After adjustment for age and gender, scores for bodily pain were poorer in patients with no ulceration (d = -10.5, 95% CI - 20.6 to - 0.4, p = 0.042) indicating greater pain in these patients compared with the cases with ulceration. Activities of daily living determined by the modified Barthel scale showed reduced self-care (d = -7.6, 95% CI -12.5 to - 2.7, p = 0.010) and mobility (d = -9.2, 95% CI -14.6 to - 3.8, p = 0.001) in patients with pressure ulceration. The overall ability to perform these activities was also significantly poorer in this group (d = -16.3, 95% CI -27.3 to -5.3, p = 0.004). While patients with pressure ulceration experience some deficits in their health-related quality of life compared with a normal population, these differences are similar to those experienced by other patients receiving community nursing care.     

Three novel PROC gene lesions causing protein C deficiency

Hallam PJ, Mannucci P, Tripodi A, Bevan D, Laursen B, Tengborn L, Wacey A, Cooper DN. Three novel PROC gene lesions causing protein C deficiency. Clin Genet 1998: 54: 231–233. 0 Munksgaard, 1998
Missense mutations. three of them novel (Am210→Val, Asn248→ Ile, Ah355→Val), were found in the protein c ( PROC ) genes of 7 patients with inherited protein C deficiency associated with venous thrombosis. Comparison with the phenotypic effects of mutations in the analogous residues of factor IX causing hdernophilia B and the use of molecular modelling has provided explanations as to how these lesions might alter either the structure, function or secretion of the protein C molecules encoded.     

Intestinal infections by Eimeria (s. l.) vanasi n. sp. (Eimeriidae, Apicomplexa, Protozoa) in cichlid fish

Eimeria (s. l.) vanasi n. sp. is described from the intestine of a variety of cichlids in Israel and South Africa. Merogony and gamogony stages are both intra- and epiepithelial, Sporogony is exogenous with young zygotes being released from the fish in the faeces. Fully developed sporocysts are ellipsoid and apparently lacking both a Stieda body (characteristic of Eimeria s. st. and Epieimeria species) and a suture line (characteristic of Goussia species). In view of the present controversial generic status of piscine coccidia, the species is tentatively designated as Eimeria (s. l.) vanasi n. sp. (Eimeriidae, Apicomplexa, Protozoa).     

Frontal sinus surgery 2004: update of clinical anatomy and surgical techniques

Endoscopic frontal sinus surgery is still considered difficult, risky to perform, and likely to result in a high failure rate. We have previously reported on our technique of endoscopic frontal sinus surgery, stressing the importance of identification and preservation of natural outflow tract. Our study of frontal sinus anatomy shows that the mean frontal ostium anterior—posterior and transverse dimensions are 7.22 ± 2.78 mm and 8.92 ± 2.95 mm, respectively; therefore, dissection of obstructive structures in frontal recess leads to a wide opening of frontal sinus outflow. A key surgical landmark in our technique is the superior attachment of the uncinate process. This article provides an update of the surgical anatomy of the frontal recess region and our surgical technique, as well as a discussion of our approach to frontal sinus revision surgery.     

Unexpected pathologies in patients referred for endoscopic DCR

The objective of this study is to describe a series of patients with different pathologies mimicking nasolacrimal duct obstruction (NLDO), diagnosed with the use of a computed tomography (CT) scan prior to a scheduled endoscopic dacryocystorhinostomy (DCR). This study is a retrospective report. We reviewed the medical records of 47 consecutive patients (57 sides) with long-standing epiphora between 2007 and 2012. All patients were referred to our tertiary Medical Center with a diagnosis of NLDO and were expected to undergo endoscopic dacryocystorhinostomy (DCR). They all underwent routine sinus CT scan prior to surgery. All scans, as well as the demographic and medical characteristics of these patients were reviewed. Of all 47 patients enrolled, in 4 patients (7 % of all sides), unexpected pathologies, other than nasolacrimal system distention, inflammation or infection were identified preoperatively. These included squamous cell carcinoma of the lacrimal sac and nasolacrimal duct, rhinoscleroma at Hasner’s valve region, a compressing ethmoidal mucocele and a case of dacryocystocele. These unusual pathologies mandated a different management and surgical approach. In all four cases, a preoperative CT scan helped in identifying the pathology and in localizing the lacrimal apparatus in relation to the paranasal sinuses. Different nasal, paranasal and lacrimal pathologies may mimic primary acquired NLDO. A high index of suspicion, a thorough clinical evaluation and utilizing preoperative imaging may lead to an alteration of patient management and to a completely different surgical approach.
