Reverse LISS plating for intertrochanteric Hip Fractures in elderly patients

Background  

Fractures of the intertrochanteric hip are common and the treatment of unstable fractures generally requires an operative approach. In elderly patients, osteoporosis makes internal fixation problematic and frequently contributes to failed fixation and poor clinical results. We have attempted to apply the Less Invasive Stabilization System (LISS) in reverse position for the repair of intertrochanteric hip fractures in elderly patients with osteoporotic bones. A retrospective review is presented of the cases of 28 elderly patients with stable and unstable fractures of the intertrochanteric hip treated using the reverse LISS.     

250. Die Zeitwahl zur operativen Versorgung von Jochbein-, Orbitaringund frontobasalen Sch?delfrakturen

Zusammenfassung DiePrimärversorgung von Jochbein-, Orbitaring- und frontobasalen Schädelfrakturen ist bei offenen Frakturen, Parästhesien, Mundöffnungseinschränkung, Augenmuskeleinklemmung oder Rhinoliquorrhoe angezeigt. Eineverzögerte Primärversorgung bis 2 Wochen nach Trauma wird vorgenommen, wenn durch Schwellung die Diagnostik erschwert wird oder eine Infektion vorliegt. Wenn wegen vitaler Gefährdung anästhesiologische oder neurochirurgische Gründe vorrangig sind, werdenSekundärversorgungen durchgeführt. Sie bestehen in der Osteotomie dislozierter Fragmente, Defektrekonstruktion, Orbitabodenherstellung oder -unterfütterung, strabologischen Korrekturen oder Liquorfistelverschluss.     

The relation of anthropometric parameters and echocardiography findings in the evaluation of left ventricular form and function in extreme obesity

For the characterization of the left-ventricular thickness of the wall, of the diameter and of the functional parameters in obesity in a short-term investigation on 18 extremely adipose female normotonics and 17 normotonics with normal weight the echocardiographic investigation in the M-mode in the short parasternal axis was performed. The women with overweight had a by 28% (p less than 0.001) greater fractional shortening, a by 8% (p less than 0.01) greater ejection fraction, a by 23% (p less than 0.05) greater stroke volume and a by 34% (p less than 0.001) greater cardiac output as well as a by 13% smaller left-ventricular end-systolic volume than normotonic women with normal weight. Index of stroke volume and cardiac output did not differ. The women with overweight had a significantly larger left-ventricular end-diastolic diameter and a thicker interventricular septum as well as a larger thickness of the left-ventricular posterior wall in the systole. The results allowed the conclusion that changed left-ventricular parameters both with regard to the form and to the function in obesity per se might be the expression of the physiological adaptation to an increased requirement and the borderlines to the transition into a disturbed left-ventricular function and development of a left-ventricular hypertrophy were not fixed. Long-term studies should bring further explanation concerning these problems.     

PRIMARY MENINGOCOCCAL CONJUNCTIVITIS IN CHILDREN

SUMMARY Four cases of primary meningococcal conjunctivitis in children are reported. This represents an incidence of 2% of patients presenting with conjunctivitis to a paediatric A&E department. All were initially treated with topical chloramphenicol, followed by systemic rifampicin once the diagnosis had been established. No ocular or systemic complications developed, nor recolonisation of the conjunctiva or colonisation of the nasopharynx at follow-up (1–2 years).     

Blood transfusion exposure does not influence survival in patients with carcinoma of the breast

There is abundant evidence of immune modulation induced by exposure to blood transfusions. Some studies have demonstrated a detrimental effect of transfusion on the recurrence of malignant disease and survival. We retrospectively studied the impact of blood transfusion exposure on 229 patients with breast cancer who were seen from July 1973 to September 1980, had at least 5 years' follow-up and had been randomized by therapy at the time of diagnosis. The patients were divided into four groups according to transfusion history: Group 1 (111 patients), no transfusion; Group 2 (34 patients), first transfusion after mastectomy; Group 3 (41 patients), first transfusion at mastectomy; and Group 4 (43 patients), first transfusion before mastectomy. All transfused patients received red cells or whole blood or both. At the time of analysis, 124 (54%) of the patients had died. Only Group 2 was statistically associated with decreased survival; recurrence of disease was 85 percent in this group, compared with 53 percent to 61 percent in the other three groups (p = 0.006, log-rank test). In general, Group 2 patients received transfusions because of recurrent disease. We conclude that transfusions before or at mastectomy are not associated with increased recurrence or reduced survival in patients with breast cancer.     

Antihypertensive efficacy of metoprolol XL/Low dose chlorthalidone (6.25 mg) combination: a randomized,comparative study in Indian patients with mild-to-moderate essential hypertension

Objective

High blood pressure is one of the most important risk factors, directly responsible for increasing the cardiovascular morbidity and mortality. The primary objective was to evaluate the efficacy of metoprolol XL/chlorthalidone against metoprolol XL/hydrochlorothiazide with respect to mean fall in systolic and diastolic blood pressure. The secondary objective was to compare the response rates and to evaluate the tolerability of study medications in patients with mild-tomoderate essential hypertension.

Methods

Total 130 eligible patients (65: metoprolol XL 25 mg/chlorthalidone 6.25 mg; 65: metoprolol XL 25 mg/HCTZ 12.5 mg) were enrolled in this randomized, comparative, multicentric, 12-weeks study. Sixty-two patients from each group completed the study. After 4-weeks of treatment, non-responders from chlorthalidone 6.25 mg combination group were shifted to metoprolol XL 50 mg/chlorthalidone 12.5 mg and non-responders from HCTZ 12.5 mg combination group were escalated to metoprolol XL 50 mg/HCTZ 12.5 mg.

Results

The study treatment groups were comparable with respect to demography and baseline disease characteristics. Both the starting therapies were comparable with respect to mean fall in SBP (p = 0.788) and DBP (p = 0.939), and response rates (p = 1.0) after 4-weeks of therapy. Also both the step-up therapies showed similar mean fall in SBP (p = 0.277) and DBP (p = 0.507) at the end of 12-weeks. However, significantly more number of patients from chlorthalidone 12.5 mg/metoprolol XL 50 mg group responded to therapy as compared to that from HCTZ 12.5 mg/metoprolol XL 50 mg group (p = 0.045). All the reported adverse events were of mild-to-moderate intensity. There were no clinically significant trends in electrolytes (Na⁺, K⁺, Cl^-)and fasting blood sugar, evident across the treatment groups.

Conclusion

Chlorthalidone in combination with metoprolol XL is as effective and well tolerated as widely used combination of metoprolol XL/HCTZ, thus providing an alternative therapeutic option.
