Internal ophthalmoparesis: an uncommon complication of varicella, a common disease

Two cases are represented with ocular complications after varicella. In one case the complication was diagnosed as internal ophthalmoparesis and in the second patient the complication could be the same; at any rate an iridoplegia was present. From the cases presented in the literature we found that there seems to be a predilection for males to contract this type of ocular complication. The association of this complication and meningo-encephalitis is rare. Recovery of the pupillary reactions and accommodative power is almost never complete. The interesting observation that decrease in cell-mediated immunity but not in humoral immunity decides whether the clinical disease will manifest itself as herpes zoster or varicella is brought forward.     

Massive hemoptysis as a rare complication in a patient with cystic fibrosis

A female patient, 28 years old, with massive haemoptysis as a complication of cystic fibrosis, is described. Cystic fibrosis is a systemic disease with common pulmonary manifestations. Chronic inflammatory process causes the proliferation of bronchial arteries, and their erosion is followed by bleeding. Transitory haemoptysis is common in patients with cystic fibrosis, but massive haemoptysis is a rare complication of this disease.     

Pulmonary gangrene occurring as a complication of pulmonary tuberculosis

Eighteen well-documented cases of pulmonary gangrene as a complication of bacterial pulmonary infections have been reported in the literature. These infections were due to Klebsiellapneumoniae, Streptococcus pneumoniae, and Hemophilus influenzae. We describe four patients with pulmonary tuberculosis who developed pulmonary gangrene. Vascular thrombosis and arteritis were found in three of these four patients, and this vascular complication seems to be necessary for the development of pulmonary gangrene.     

Articular interposition of trochanteric wires in a failed total hip replacement

This is a case report of a previously unrecorded complication of trochanteric osteomy in a total hip arthroplasty. The trochanteric wire fixation failed and wire fragments migrated from the osteotomy site into the joint space. Revision total arthroplasty was elected. An additional potential complication of trochanteric osteotomy is noted.     

Thyroid carcinoma originating in a teratoma of the ovary

The malignant degeneration of a cystic teratoma of the ovary is a rare complication which different authors place at between 0.8 to 4%. Adenocarcinomas represent a relatively rare complication, 8% of secondary cancers, those of thyroid origin being reported in only 5 cases. The aim of this paper is to present the sixth such case of thyroid carcinoma developed in a mature teratoma in the ovary.     

Relationship between polymorphism of N-acetyltransferase gene and susceptibility to colorectal carcinoma in a Chinese population

Type II phospholipase A2 (type II PLA2), nitrite/nitrate (NOx), tumor necrosis factor-alpha (TNF-alpha) and endotoxin were studied in burn patients. Type II PLA2 values and NOx values were both significantly higher in the group that died, the group with shock as a complication and the group with multiple organ dysfunction syndrome (MODS) as a complication, than in the group that survived, the group without shock as a complication and the group without MODS as a complication, respectively. The results suggested that type II PLA2 and nitric oxide (NO) may play a major role in the pathology of burn patients. Significant correlations were found between TNF-alpha and type II PLA2 values and between type II PLA2 and NOx values, suggesting the possibility of involvement in each other's production.     

Central diabetes insipidus: a complication of ventriculoperitoneal shunt malfunction during pregnancy

During pregnancy ventriculoperitoneal shunts have reported complication rates of 30% to 60%. In this case a functionally occluded shunt resulted in prolonged increased intracranial pressure, pituitary stalk damage, and permanent central diabetes insipidus. This complication of ventriculoperitoneal shunt occlusion during pregnancy has not been previously reported.     

Pulmonary abscess as a complication of transarterial embolization of multinodular hepatocellular carcinoma

Hepatic transarterial embolization has been widely used in the treatment of hepatocellular carcinoma and other liver tumors. Despite being a safe treatment, some complications associated with this procedure have been described. The most frequent adverse effect of transarterial embolization is postembolization syndrome, whereas infections account for only 3.4% of complication. We report the first case of lung abscess as a complication of transarterial embolization used in the treatment of multinodular hepatocellular carcinoma.     

The Werner syndrome protein is a DNA helicase

The cosmetic injection of exogenous lipids and more recently of polydimethyl siloxane (injectable silicone) into the scrotum has been described since 1899. Sclerosing lipogranuloma and paraffinoma are terms applied to a complication of this practice in which the injected oils or silicone elicit a marked granulomatous reaction with prominent surrounding fibrosis. Although this complication has been described as a localized process occurring mainly in the scrotal area and regional lymph nodes, few studies have documented systemic manifestations. In this report we describe the autopsy findings of a 48-year-old man who had scrotal and systemic lipogranulomas from repeated self-administered injection of mineral oil. In addition, severe acute pulmonary edema resulted in sudden unexpected death. To our knowledge, this fatal complication of exogenous lipogranuloma has not been previously reported.     

Aortic balloon control of a traumatic aortoenteric fistula after damage control laparotomy: a case report

Aortoenteric fistula is a rare complication of abdominal trauma. We present a case of a patient with multiple gunshot wounds to the abdomen and thorax in whom control of injury required staged operations. An aortoenteric fistula developed, presenting a diagnostic and therapeutic challenge. The operative control of aortic bleeding was by a retroperitoneal approach to the aorta and facilitated by the use of percutaneous aortic balloon catheters. The patient survived to leave hospital. This case highlights a rare trauma complication, the use of "damage control" for the severely injured abdomen and the technique of intra-arterial balloon control of bleeding from inaccessible locations.     

Patch migration: a serious late complication of thoracotomy lead systems

Thoracotomy patch leads used for implantable cardioverter defibrillators (ICDs) are generally safe and effective. We describe two patients in whom a late complication of patch lead migration occurred years after the original implants, causing a bronchopleural fistula in one and lingular lobe collapse in the other patient. We conclude that patch migration is a late but possible complication of extrapericardial ICD leads, and should be suspected in patients who present with hemoptysis, atypical pneumonia, or lung collapse after the initial ICD surgery.     

Calcified catheter "cast": a rare complication of indwelling central venous catheters in infants

Peri-catheter calcification is an unusual and previously unreported complication of central venous (CV) catheterization in infants. A 1. 9 Fr Silastic CV catheter was placed in a term infant for administration of total parenteral nutrition and antibiotics following intra-abdominal sepsis. The catheter was removed, without complication, at a later date after another septic episode. Imaging studies performed in the investigation of a possible intra-abdominal abscess revealed a cylindrical density within a clot in the inferior vena cava (IVC). The density was presumed to be a retained catheter fragment. Further investigation indicated total occlusion of the IVC. Surgical exploration of the IVC revealed only a calcified thrombus. This case represents a rare and previously unreported complication of CV catheterization in infants. Diagnosing this condition on radiographic evidence alone can be difficult. It is hoped that awareness of the potential for this complication will avoid unnecessary invasive procedures in the future. We also suggest a high level of clinical suspicion and routine Doppler ultrasound investigations to detect IVC thrombosis when indwelling CV catheters are used in infants.     

Postesophagectomy mediastinal chylothorax causing upper airway obstruction misdiagnosed as asthma: a report of two cases

Injury to the thoracic duct resulting in chylothorax is an uncommon but well-documented complication of esophagectomy. In two cases, which were associated with signs of life-threatening upper airway obstruction, an initial diagnosis of asthma was made. It appears that this complication of esophagectomy has not been reported previously.     

Subcapsular hematoma as a complication of acute pyelonephritis: a case report

A case of subcapsular hematoma, a rare complication of acute pyelonephritis (APN) is described. A 60-year-old diabetic woman was admitted with a 3 day history of fever and left flank pain due to acute pyelonephritis. On the third day in hospital, left flank pain worsened despite use of antibiotics available for the treatments of APN and hemoglobin rapidly decreased from 11.1 to 7.9 g/dL. Ultrasonography and abdominal CT showed left subcapsular hematoma. Renal angiography demonstrated an ovoid avascular zone between the capsular artery and parenchyme of the left kidney with no evidence of tumors or vascular abnormalities, such as arteriovenous malformation or fistula. Subsequent percutaneous drainage of this subcapsular hematoma was performed and showed old blood-colored drainage. Hereby, the possibility of subcapsular renal hematoma in the course of acute pyelonephritis is stressed as a rare complication.     

Method for evaluating long term complications. A study from a phase III trial comparing two low dose rates in gynecologic brachytherapy

When treatment complications are the main criteria of a study, the simplest way for estimating the complication rate over time is to use the Kaplan-Meier method. The failure is the onset of the first complication. A new way is proposed here which takes into account the time to an eventual second, and third complication, and their duration as well. Results from a phase III randomized trial comparing two preoperative brachytherapy low dose rates in localized stage cervix carcinoma patients are used to illustrate both methods. The new method showed a greater long term complication rate in the higher dose rate group.     

Unusual complication of self-catheterization in a patient with a continent stoma

The authors report a case of acute urinary retention due to a knot in the the catheter, in a patient performing self-catheterization. They describe a simple technique for emergency relief of retention, by creating additional apertures in the catheter, and then discuss the preventive measures of this type of complication.     

Septic arthritis of the hip by Fusobacterium necrophorum after tonsillectomy: a form of Lemierre syndrome?

Lemierre syndrome used to be a complication of severe oropharyngeal infection with regional thrombophlebitis, septicaemia and septic metastatic infections caused by Fusobacterium necrophorum in the pre-antibiotic era. A case of septic arthritis of the hip caused by F. necrophorum as a complication of tonsillectomy is reported in a 9-year-old boy. Conclusion: Lemierre syndrome, usually seen after an oropharyngeal infection, can also complicate tonsillectomy.     

Management of iatrogenic spinal stenosis complicating placement of a fusion cage. A case report

STUDY DESIGN: A case of iatrogenic spinal stenosis secondary to fusion cage retropulsion is presented. OBJECTIVES: To highlight fusion cage retropulsion, a potential complication that may become more prevalent as the use of fusion cage instrumentation expands. The difficulty in management of this complication is emphasized. SUMMARY OF BACKGROUND DATA: Early reports regarding fusion cage instrumentation have been encouraging. At this point, however, the potential benefits are better defined than the potential complications. METHODS: A significant complication of fusion cage instrumentation and the limited literature on this subject are reviewed. RESULTS: The patient underwent successful revision surgery after retropulsion of a fusion cage, however, an extensive surgical procedure including partial vertebral body resection was required. CONCLUSIONS: The frequency and severity of complications related to fusion cage instrumentation remain poorly defined. Caution should be used in patient selection until additional experience more clearly defines the risk-to-benefit ratio for a given application of this new technology.     

Hodgkin's disease presenting with a bronchoesophageal fistula

Bronchoesophageal fistula is a rare complication of Hodgkin's disease. We report a case of Hodgkin's disease presenting with a bronchoesophageal fistula that was successfully treated with bipolar esophageal exclusion and substernal gastric bypass. Direct invasion from mediastinal lymph nodes was the probable cause. Although bronchoesophageal fistula can result as a complication during the course of treatment for Hodgkin's disease, it rarely occurs as the presenting feature. Early recognition and surgical treatment are key aspects of management.     

Lipoprotein(a) and other lipids after oophorectomy and estrogen replacement therapy

We present a case report of uretero-acetabular fistula in a female complicating orthopaedic surgery of congenital coxal difformity. An ileal pedicle graft was used to replace the terminal ureter. The difficulty of such complication is to choose the best the rapeutic strategy between surgical and non surgical techniques. We review here the various urological armamentarium to affront such a rare and multifactorial complication.
