Pulmonary embolism after minor elective orthopedic procedure

The occurrence of pulmonary embolism, in spite of thromboprophylaxis after a minor elective orthopedic surgery (release of m. rectus femoris tendon) is reported. In case of this severe complication, an early diagnosis is of outmost importance to enable optimal therapy introduction. Deep vein thrombosis and pulmonary embolism are frequent complications after total joint replacement, however, they may also develop after minor surgical orthopedic procedures. The possible causes of pulmonary embolism after release of m. rectus femoris tendon included the history of varicose veins and sclerozation of calf veins, and operative procedure with intraoperative pressure upon large veins of the iliofemoral region, which may and is expected to occur during this procedure. The importance of thrombopropylaxis in orthopedic surgical procedures is emphasized by this case presentation.     

Acute erythremic myelosis (DiGuglielmo) following atypical aplastic anemia

A patient presented with acute erythromyelosis (DiGuglielmo) which was developed after 3 yr of aplastic anemia. Aplastic anemia differed from the classical form, since erythroid cells and megakaryocytes were relatively preserved in the bone marrow. Treatment with androgens induced the increase of hematocrit and reticulocyte as well as general improvement. The sudden appearance of hemorrhagic syndrome due to thrombocytopenia was associated with aggravation of anemia and granulocytopenia. In the bone marrow, giant multinuclear proerythroblasts with bizarre nuclear morphology and PAS positivity with coarse granules was found. Serum erythropoietin (Ep) level was high. Bone marrow cells culture in vitro revealed two types of erythroid colonies: typical and giant multinuclear cells, both benzidine-positive. The number of colonies was irrespective to the Ep dose. "Autonomous" Ep independent growth of these colonies was also demonstrated. The number of colonies was more than 3 times higher per number of cells seeded when compared to normals, which indicated malignant proliferation and Ep independent growth. Treatment with 6-mercaptopurine and transfusions was without effect and the patient died after 15 days with signs of cerebral bleeding.     

Does Drinking Coffee and Tea Affect Bone Metabolism in Patients with Inflammatory Bowel Diseases?

Patients suffering from Crohn’s disease and ulcerative colitis are at higher risk of osteoporosis due to lower bone mineral density. Risk factors of osteoporosis are divided into unmodifiable, namely, age, gender, genetic factors, as well as modifiable, including diet, level of physical activity, and the use of stimulants. Coffee and tea contain numerous compounds affecting bone metabolism. Certain substances such as antioxidants may protect bones; other substances may increase bone resorption. Nevertheless, the influence of coffee and tea on the development and course of inflammatory bowel diseases is contradictory.     

Progressive tubulointerstitial nephritis and chronic cholestatic liver disease

We report the clinical and morphological features of a distinctive hepatorenal disorder in four patients and review the five similar patients in the literature. The main clinical characteristics were early onset of cholestatic liver disease and progressive tubulointerstitial nephritis leading to renal death in early childhood. Liver histology showed disturbed architecture with nodular and acinar formations and portal fibrosis and bile duct proliferation. Histological abnormalities in the kidney were severe interstitial fibrosis and tubular atrophy and dilatation, while the typical features of nephronophthisis were lacking. These clinical and morphological characteristics distinguish our patients from the majority described, as having nephronophthisis and congenital hepatic fibrosis or any other known syndrome with concomitant hepatorenel involvement. We suggest that the association of cholestatic liver disease and progressive tubulointerstitial nephritis represents a new syndrome.     

Incidence of IDDM during 1988–1992 in Zagreb,Croatia

Summary The objective of this study was to determine the incidence of insulin-dependent diabetes mellitus (IDDM) in the population of Zagreb, Croatia, during 1988–1992. A centralized diabetes registry was the primary source of data, while secondary sources were used to assess ascertainment. A total of 282 new cases of IDDM were diagnosed in the study period, the primary and secondary sources identifying annually 93–100% of the cases. The annual incidence rate ranged from 5.6 per 100,000 to 6.6 per 100,000. Early fatality in persons older than 50 years was the major cause of underascertainment. The incidence peaked in the 10–14 years age group (12.4 per 100,000), and remained stable after age 24 years. Males had a significantly higher incidence in the 5–9 and 24–44 years age groups. In the 45–54 years age group, females had a significantly higher incidence. No seasonality was observed. Despite the war conditions in Croatia, the low overall IDDM incidence rates did not change significantly during the study period.Abbreviations IDDM Insulin-dependent diabetes mellitus - DKA diabetic ketoacidosis     

An external approach without tracheotomy for submucosal cordectomy with laterofixation for bilateral abductor paralysis of the vocal folds

There are numerous surgical procedures now available to manage bilateral abductor paralyses of the vocal folds. These procedures have various success rates but mostly do not offer reliable and predictable postoperative results, and usually require ,tracheotomy. The technique described in this report is based on a trial study to obtain a safe airway for an affected patient and avoid tracheotomy, if possible. Submucosal cordectomy was used with lateral fixation of one vocal fold and preservation of the arytenoid. The procedure was performed by using continuous intravenous anesthesia, which does not require intubation of the patient's airway. Seven patients were operated with this technique with excellent postoperative results. The glottal airway was largely improved in all patients, with only minor temporary complications.
