Status and perspectives of hospital mortality in a public urban Hellenic hospital, based on a five-year review
<p>Abstract</p> <p>Background</p> <p>Analysis of hospital mortality helps to assess the standards of health-care delivery.</p> <p>Methods</p> <p>This is a retrospective cohort study evaluating the causes of deaths which occurred during the years 1995â1999 in a single hospital. The causes of death were classified according to the International Statistical Classification of Diseases (ICD-10).</p> <p>Results</p> <p>Of the 149,896 patients who were discharged the 5836 (3.4%) died. Males constituted 55% and females 45%. The median age was 75.1 years (1 day â 100 years).</p> <p>The seven most common ICD-10 chapters IX, II, IV, XI, XX, X, XIV included 92% of the total 5836 deaths.</p> <p>The most common contributors of non-neoplasmatic causes of death were cerebrovascular diseases (I60âI69) at 15.8%, ischemic heart disease (I20âI25) at 10.3%, cardiac failure (I50.0âI50.9) at 7.9%, diseases of the digestive system (K00âK93) at 6.7%, diabetes mellitus (E10âE14) at 6.6%, external causes of morbidity and mortality (V01âY98) at 6.2%, renal failure (N17âN19) at 4.5%, influenza and pneumonia (J10âJ18) at 4.1% and certain infectious and parasitic diseases (A00âB99) at 3.2%, accounting for 65.3% of the total 5836 deaths.</p> <p>Neoplasms (C00âD48) caused 17.7% (n = 1027) of the total 5836 deaths, with leading forms being the malignant neoplasms of bronchus and lung (C34) at 3.5% and the malignant neoplasms of large intestine (C18â21.2) at 1.5%. The highest death rates occurred in the intensive care unit (23.3%), general medicine (10.7%), cardiology (6.5%) and nephrology (5.5%).</p> <p>Key problems related to certification of death were identified. Nearly half of the deaths (49.3%: n = 2879) occurred by the completion of the third day, which indicates the time limits for investigation and treatment. On the other hand, 6% (n = 356) died between the 29<sup>th </sup>and 262<sup>nd </sup>days after admission.</p> <p>Inadequacies of the emergency care service, infection control, medical oncology, rehabilitation, chronic and terminal care facilities, as well as lack of regional targets for reducing mortality related to diabetes, recruitment of organ donors, provision for the aging population and lack of prevention programs were substantiated.</p> <p>Conclusion</p> <p>Several important issues were raised. Disease specific characteristics, as well as functional and infrastructural inadequacies were identified and provided evidence for defining priorities and strategies for improving the standards of care. Effective transformation can promise better prospects.</p
Aggressive Chordomas: Clinical Outcome of 13 Patients
The authors reviewed the files of all patients with chordomas who were
admitted and treated at their institutions from 1975 to 2012. Patients
were categorized by early local recurrence and metastasis. Aggressive
clinical behavior was defined as local recurrence and metastasis within
24 months of diagnosis and adequate treatment (wide en bloc resection
with microscopically negative tumor margins). According to these
criteria, 13 patients (14.3%) had aggressive chordomas, including 7 men
and 6 women, with mean age of 54 years (range, 37-65 years) at diagnosis
and treatment. All patients had preoperative tumor biopsy, followed by
resection with partial (7 patients) or total sacrectomy (6 patients). In
all cases, biopsy and histologic analysis of resected tumor specimens
showed conventional chordomas. Resection margins were wide (grossly
negative) in 6 patients and wide contaminated in 7 patients. Mean
maximum tumor diameter was 11.8 cm (range, 5-21 cm). Mean follow-up was
43 months (range, 8-131 months). Rates of local recurrence, metastasis,
and death were evaluated. At the last follow-up, all patients had local
recurrence at a mean of 13 months (range, 5-22 months). Histologic
examination of recurrent tumors showed a dedifferentiated chordoma with
a fibrosarcoma component in 2 patients and no histologic change in the
remaining patients. In addition, 8 patients had metastases at a mean of
13 months (range, 4-24 months) and died of their disease. All histologic
findings of metastatic lesions were similar to those of primary tumors.
Early diagnosis of aggressive tumors requires close follow-up of
patients with chordomas. Metastasis is common, with resultant poor
survival
Intercalary reconstructions after bone tumor resections: a review of treatments
An intercalary reconstruction is defined as replacement of the diaphyseal portion of a long bone after segmental skeletal resection (diaphysectomy). Intercalary reconstructions typically result in superior function compared to other limb-sparing procedures as the patient's native joints above and below the reconstruction are left undisturbed. The most popular reconstructive options after segmental resection of a bone sarcoma include allografts, vascularized fibula graft, combined allograft and vascularized fibula, segmental endoprostheses, extracorporeal devitalized autograft, and segmental transport using the principles of distraction osteogenesis. This article aims to review the indications, techniques, limitations, pros and cons, and complications of the aforementioned methods of intercalary bone tumor resections and reconstructions in the context of the ever-growing, brave new field of limb-salvage surgery

Tumors of the Sacrum - Diagnosis and Treatment of Benign and Malignant Tumors
This book provides an up-to-date overview on the epidemiology, clinical presentation, and imaging characteristics of sacral tumors, discusses the available treatment options, and reports the published outcomes. The diagnostic roles of conventional radiology, CT, and MRI are thoroughly described and imaging appearances are compared with the histologic features. The coverage of therapeutic approaches includes chemotherapy, radiotherapy, radiosurgery, and surgery (partial or total sacrectomy and spinopelvic reconstruction). Special attention is paid to the specific anatomic constraints that make tumors in this region of the spine more difficult to manage effectively than those in the extremities and the mobile portions of the spine.
All components of the sacrum can give rise to benign or malignant tumors, which pose significant diagnostic and therapeutic challenges. Although these tumors are often diagnosed at an advanced stage, good clinical outcomes may be achieved if an aggressive multidisciplinary approach is used. This book will be of value for a range of practitioners; it will assist in prompt diagnosis and help to overcome lack of familiarity with the required treatment strategies
