Upper esophageal stenosis: two case reports

Esophageal stenosis caused by an intrinsic congenital deformity is uncommon in infants and children. The main forms of stenosis are congenital esophageal web congenital stricture caused by tracheobronchial remnants, and congenital idiopathic muscular hypertrophy. The authors report on two patients who were successfully treated and managed after being diagnosed as having upper esophageal stenosis. One patient underwent resection of the web and primary anastomosis of the esophagus and was discharged 6 days after surgery. After 1 year, this patient has had no symptoms of dysphagia or other postoperative difficulties. The second patient underwent balloon dilatation of the esophageal stricture and was discharged on the day of surgery; however, this patient required numerous repeat dilatations.     

Correcting high anisometropia: two case reports

In the cases reported, the anisometropia had not been corrected previously. Despite the common belief that such a correction would induce intolerable symptoms in adults, both patients successfully adapted to the full correction within a few days, showing marked improvement in binocular vision skills.     

Reactive airways dysfunction syndrome: two case reports

The antimicrobial susceptibilities of 1058 Staphylococcus aureus and 2,163 coagulase-negative staphylococci (CNS) isolates obtained from clinical specimen between 1988 and 1995, were determined against 13 anti-staphylococcal antibiotics. During the study period the resistance of Staphylococcus aureus to ciprofloxacin, ceftazidime, and norfloxacin increased significantly by 7%, 4%, and 6%, respectively (p < or = 0.001). By comparison, the antibiotic resistance of CNS to ceftazidime, oxacillin, norfloxacin, ciprofloxacin, fusidic acid, and cefoxitin increased by 20%, 17%, 15%, 14%, 12% and 10%, respectively (p < or = 0.001). Invasive and noninvasive S. aureus had similar antibiotic resistance, whereas CNS invasive isolates were more resistant than noninvasive isolates to every antibiotics, except vancomycin and fusidic acid. These differences were significant (p < 0.001) for oxacillin, cefoxitin, and clindamycin. Our observations confirm that staphylococci and particularly CNS isolates show an important rate of increased resistance to the standard antimicrobials used for therapy, and that the rate of emergence of resistance differ considerably between coagulase-positive and coagulase-negative staphylococci.     

Non-atherosclerotic coronary artery aneurysms: two case reports

Non-atherosclerotic isolated coronary artery aneurysm is not common. Two cases of non-atherosclerotic isolated coronary artery aneurysm, with similar presentations but different management strategies were presented. The patients were well four and six years later, respectively. The definition, incidence, causes, presentation, complications, investigations, management, and prognosis of coronary artery aneurysms are discussed. The difficulties of determining pathogenesis and different management strategies are highlighted. An isolated coronary artery aneurysm should be managed on its merits.     

Gastric metastases of melanoma: two case reports

Primary hydatid cyst of the brain in adults is rare and can pose various diagnostic problems. Multiplicity of these cysts is even rarer. The most important diagnostic tool is computed tomography scanning of the brain. Hydatid cyst should be included in the differential diagnosis when a cystic brain lesion is found in patients from an endemic echinococcosis area.     

Necrotizing dermatitis, infections of soft tissue and deep fascia: classification and treatment

Using the model systems of Pb-Sr intoxication on the white rats was found out, that incorporated Pb and Sr had influenced on the activity of lipoperoxidation in tissue of rat's internal organs. The intensification of the activity of lipoperoxidation was observed in liver, heart, spleen, less in kidneys after five days Pb-Sr intoxication. Twenty-days Pb-Sr intoxication was accompanied the depression of the activity of lipoperoxidation in liver, heart, kidneys; the activity of lipoperoxidation's activation was continued in spleen. Using phlamicare--polyextract of mountain ash, is resulted in normalisation of lipoperoxidation in rat's internal organs during Pb-Sr intoxication and contributed to removing of incorporated Pb and Sr.     

Fistula carcinoma in chronic soft tissue infection

Squamous cell carcinoma without accompanying osteomyelitis is a rare complication in chronic soft tissue inflammation. We report on a patient with soft tissue squamous cell carcinoma developing only two years after a war accident.     

Isolated superior gluteal nerve injury: two case reports

Isolated superior gluteal nerve injury has been infrequently described in the literature, mainly from injections or hip surgery. Its course through the greater sciatic foramen renders it at risk in pelvic or hip trauma. We report 2 cases of electromyographically documented isolated superior gluteal nerve injury following pelvic trauma. These cases illustrate that weakness in hip abduction following pelvic trauma may indicate the presence of a superior gluteal nerve injury, warranting further clinical and electrodiagnostic evaluation.     

Orthotopic heart transplantation: a case report

In July 1994, we performed orthotopic heart transplantation for a patient with hypertrophic myocardiopathy, who had had open heart surgery enlarging the right ventricular outlet. The patient had an excellent postoperative result. He received triple-drug immunosuppressive therapy. Large dose of methyl-prednisolone was used successfully for his acute rejection reaction. At present, the patient is living well with good cardiac, hepatic and renal function. We described donor heart harvest, myocardial protection, operative procedure, immune monitoring, anti-rejection and anti-infectious therapy. We introduced the process of protecting donor heart on the way to hospital by retrograde perfusion with medium hypothermic oxygenated-blood combined with St. Thomas cardioplegia. Besides endomyocardial biopsy, other noninvasive examinations such as noninvasive cardiac output monitoring could be helpful to monitor acute rejection reaction.     

Body-background defects with 99mTc-DTPA after renal transplantation: case reports

Photon-deficient areas adjacent to transplanted kidneys were seen in the early phases of several dynamic studies obtained with 99mTc-diethylenetri-aminepentaacetic acid (99mTc-DTPA). The causes included hematoma, urinoma, and lymphocele. These fluid collections do not readily exchange as part of the extracellular space and, if sufficiently large, may be visualized as photon-deficient areas in the normally homogeneous background of 99mTc-DTPA studies.     

Foreign-body abscesses presenting as soft-tissue tumours: two case reports

Green function analysis of the Fokker-Planck equation was used to describe protein conformational motion for approximate variational derivation of typical rate constant of protein relaxation from excited nonequilibrium state to the equilibrium. This approach was illustrated on a simple one-dimensional conformational potential.     

Large benign pineal cysts: two case reports with review

Skin biopsies at the plaque regions and adjacent skin obtained from HIV-infected 22-40-year-old patients with Kaposi's sarcoma have been analyzed. Morphological changes revealed depended on the stage of the disease and cell specificity. The alterations were as follows: cell adenoma with degeneration and destruction of cell organelles, changes of the specific granules and microfilaments. Langerhans cells appeared to be most susceptible to HIV and showed all types of changes. In the course of the disease gradual decrease of the activity of the main metabolic enzyme - adenylate cyclase - was recorded.     

Disseminated acanthamoeba infection in patients with AIDS: case reports and review

Acanthamoeba infection has been described as an opportunistic infection in persons with AIDS. We report two cases of patients with AIDS and acanthamoeba infection and review the manifestations of this protozoan infection in patients infected with human immunodeficiency virus. The diagnosis of this infection requires a high index of suspicion because the clinical and histologic manifestations may be confused with those of disseminated fungal or algal disease. Clinicians and laboratory personnel should be aware of this potentially fatal condition so that appropriate diagnostic studies can be performed and treatment can be urgently administered. Early initiation of therapy may alter the clinical outcome of the disease.     

Manipulation under epidural anesthesia with corticosteroid injection: two case reports

OBJECTIVE: To discuss the combined use of selective epidural steroid injection (ESI) and spinal manipulative therapy (SMT) in treating recalcitrant lumbar radiculopathy. CLINICAL FEATURES: In a first case, a patient suffered from numbness and pain in an S1 dermatome distribution 6 months after undergoing lumbar discectomy. Clinical correlation with advanced imaging led to the diagnosis of L5 intervertebral disc (IVD) syndrome with peridural scar formation. In a second case, a patient suffered from low-back and right-leg pain of 9 months' duration. Various forms of conservative treatment were not effective. A diagnosis of L4 IVD syndrome with radiculopathy was made. INTERVENTION AND OUTCOME: The first patient received conventional treatments, including physical therapy, SMT, fluoroscopically guided ESI and oral medications, with consistent but short-lived response. A team consisting of an anesthesiologist (dedicated spinal injectionist) and chiropractor performed manipulation under epidural anesthesia (MUEA) with corticosteroid injection. Follow-up at 60 days showed marked improvement in visual analogue scale, pain drawing and Oswestry pain and disability index. The second patient received all of the same conventional care except ESI before the combined procedure. The patient underwent MUEA, followed up with eight sessions of stretching and manipulation over the ensuing 3 wk. At 45 days after the combined procedure, the patient had a negative SLR (previously positive at 70 degrees), no leg pain and a marked reduction in back pain. CONCLUSION: This article discusses an integrated procedure that combines two standard treatments that may act synergistically. Our positive results are consistent with other reports, both published and anecdotal. The technique of MUEA warrants further investigation by the health care industry.     

Successful removal of large pineal region meningiomas: two case reports

BACKGROUND: Pineal region meningiomas are extremely rare tumors and comprise about 8% of tumors of this region. Two cases of large pineal region meningiomas in young males are presented. METHODS: Computed tomography (CT) scan and cerebral angiography were used to evaluate the patients preoperatively. Both patients were operated on through an occipital transtentorial approach either as a single- or two-stage procedure. RESULTS: Preoperative work-up revealed that both tumors received their main blood supply from the posterior lateral choroidal arteries and were therefore originating from the velum interpositum cerebri (superior tela choroidea). Complete tumor removal was effected in the first patient using a right occipital transtentorial approach. In the second patient, after partial removal using the same approach, complete resection was achieved at a second stage via the left occipital transtentorial approach 3 months later. CONCLUSION: Cerebral angiography, which must include vertebral angiography, is important in the preoperative surgical planning of these tumors. The occipital transtentorial approach provides good access. However, a two-stage procedure using right and left sides may be necessary for large meningiomas receiving a bilateral blood supply from both posterior lateral choroidal arteries. Diagnosis, the surgical approach, and methods of tumor excision are discussed.
