Cross-sectional imaging of the pelvic tumors and tumor-like lesions in gynecologic patients-misinterpretation points and differential diagnosis

Computed tomography and/or magnetic resonance imaging were performed in 42 female patients with suspected pelvic mass. Surgical and histopathological reports were compared to the imaging findings, yielding mismatch in five (17.8%) patients. One benign cyst and one case of postirradiation fibrosis were characterized as recurrent tumors, one surgically transposed ovary as metastasis, and an ovarian torsion as ovarian tumor, and a pelvic hematoma was mistaken for abscess. The most common false-positive finding on a per-lesion basis was that of enlarged lymph nodes.     

The differences of water diffusion between brain tissue infiltrated by tumor and peritumoral vasogenic edema

The differences between peritumoral brain tissue infiltrated by tumor and vasogenic edema were prospectively evaluated by comparing the apparent diffusion coefficient (ADC) of peritumoral areas of infiltrative tumors (anaplastic astrocytomas and glioblastomas) to that of peritumoral areas of noninfiltrative tumors (metastatic carcinomas) on 54 patients.Peritumoral ADCs indicated the possibility of differentiation between tumor infiltration and vasogenic edema, as well as between primary gliomas and metastases.     

Inflammatory epidermolysis bullosa acquisita in a 4‐year‐old girl

This study presents a case of linear immunoglobulin A dermatosis‐like epidermolysis bullosa acquisita in a 4‐year‐old girl showing rapid, widespread and inflammatory skin lesions. The diagnosis was confirmed by histopathology, direct and indirect immunofluorescence, various immunoblotting analyses and enzyme‐linked immunosorbent assays. Despite the severe clinical manifestations, the disease was successfully controlled by combination therapy of oral prednisolone and dapsone.     

Use of pedicled cutaneous groin flaps in distal reconstruction of the upper extremity]

In the years 1981-1997 at the Department of Plastic Surgery Medical Centre for Postsgraduate Education in Warsaw 116 patients were treated surgically using groin flaps and 97 patients using a pedicled cutaneous groin flap. This paper reports the results of the later technique. Reconstructions were performed in 10 female patients aged 18-58 (mean age 37.5 years) and 87 male patients aged 15-67 (mean age 33.8 years). The tissue defects or acquired deformations were caused by: crush injuries (26 cases), scalping injuries (23 cases), rugged injuries (18 cases), avulsion trauma (15 cases), explosion injuries (8 cases) and electric burns (7 cases). Flap size depended upon extent of the tissue defect and the from flaps were 7-26 cm long and 4-12 cm wide. Flap area ranged from 35 to 260 square centimetres. Emergency procedures were performed in 59 patients (61%). Secondary reconstructions were carried out in 38 cases (39%). Operative technique was based on the rules described by McGregor and Jackson. The donor site was sutured primarily tubulizing its basis--as in tube flap. The flap pedicle was cut off during a one stage procedure in 41 patients 21-30 days (mean 23 days) after surgery or during a two-stage procedure in 56 cases. The two-stage procedure consisted of an incision of part of the pedicle after 15-45 days post-op (mean 21 days) followed by a complete dissection after a few days (mean 4 days). In 44 cases the flap required modelling i.e. excision of excessives kin and/or thinning of subcutaneous tissue. The flap healed in 96 patients (99%). Complications at different stages of the treatment were observed in 40 patients (41%). In 3 cases wound ischemia was observed because of too tight suturing. Removal of skin sutures lead to normalization of blood supply. In 7 patients cyanotic skin of the distal part with no significant consequences was observed. In 27 patients (28%) necrosis of the marginal tissues surrounding the operation wound after cutting of the pedicle was noted. Besides supported necrectomy a conservative treatment was also applied by putting dressings soaked with antiseptics and 0.5% neomycine solution on a daily basis. This prolonged treatment by further several weeks. No significant complications were observed at the donor site.     

Management of arrhythmias in heart failure

Arrhythmias continue to contribute significantly to morbidity and mortality in heart failure. Implantable defibrillators have assumed an increasingly important role in preventing sudden death and are recommended for patients who have been resuscitated from cardiac arrest, have unexplained syncope, or exhibit inducible ventricular tachycardia in the setting of prior myocardial infarction. The extension of survival conferred by implantable defibrillators is likely to be limited in patients with advanced heart failure. Ongoing trials will help define the use of these devices in heart failure populations, in whom atrial fibrillation is common and rate control and anticoagulation are of major importance. Among pharmaceutical options, amiodarone and dofetilide are the major agents for maintenance of sinus rhythm. The complexity of coexistent heart failure and arrhythmia management warrants close collaboration between heart failure and arrhythmia specialists.     

Inhibitory effect of the antioxidant butylated hydroxyanisole on the activation of the carcinogen benzo(a)pyrene.

The effect of the antioxidant butylated hydroxyanisole (BHA) on benzo(a)pyrene (BP) metabolites binding to DNA, percentage of diols and phenols in the total amount of BP metabolites extracted to organic solvent, were studied in : incubation mixture of rat liver microsomes, cultured mouse embryo cells, human skin, and human lymphocytes. The amount of BP metabolites bound to DNA in mouse embryo cells and human skin decreased in the presence of BHA. No effect was found in human lymphocytes. Percent of phenols increased in mouse embryo cell cultures; percent of diols decreased in cultures of human skin and lymphocytes.     

Ogilvie's syndrome--acute colonic pseudo-obstruction. Case report and review of the literature

We present a rare entity of colonic pseudo-obstruction, characterised by severe colonic dilatation in absence of any organic obstacle. Clinical symptoms, diagnostic approach, and therapeutic measures are analysed and discussed. Many factors have been associated with this syndrome which include electrolyte imbalance, systemic infection, drugs, and occasionally, neurologic disease. Reported here is a case of acute colonic pseudo-obstruction which developed in a patient with restrictive respiratory dysfunction. Colonic decompression by means of colonoscopy, the most effective therapeutic approach for pseudo - obstruction failed, and surgical cecostomy was required. The acute colonic pseudo-obstruction, Ogilvie's Syndrome, most often appears as a complication of other clinical conditions. It is characterized by massive colonic dilatation in the absence of a mechanical cause and may lead to cecal perforation in absence of treatment. When colonic obstruction is suspected, one should always consider the possibility of the occurrence of Ogilvie's syndrome     

Fire‐eater's lung complicated by an infectious abscess requiring surgical treatment

We describe a case of fire‐eater's pneumonia that was complicated by an infectious lung abscess with substantial haemoptysis. Conservative treatment was inadequate. Surgical resection was necessary and proved to be successful.
