Successful treatment using cyclosporine A plus corticosteroid therapy in an elderly patient with severe idiopathic interstitial pneumonia

GERIATRICS & GERONTOLOGY INTERNATIONAL, Issue 2 2006
Masayuki Kikawada
An 81-year-old woman was referred to our hospital due to acute progressive respiratory failure. Her chest X-ray film showed bilateral interstitial changes and computed tomography revealed a diffuse ground-glass appearance. Histological examination of transbronchial lung biopsy specimens did not provide a final diagnosis. The patient was diagnosed as having idiopathic interstitial pneumonia (IIP) and was treated with corticosteroid therapy. The chest X-ray appearance improved temporarily after corticosteroid therapy, but the interstitial changes did not resolve and subsequently became worse again, so administration of cyclosporine A was added. After commencement of cyclosporine A, corticosteroid therapy could be gradually tapered over 10 months. This case suggests that a combination of steroid therapy with cyclosporine A is effective for severe IIP of unknown pathological diagnosis. [source]


Are we aware of all complications following body piercing procedures?

INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 4 2009
Bogus, aw Antoszewski MD
Background, The popularity of body piercing procedures is increasing around the world. Body piercing, depending on the age and social group, is believed to involve up to 51% of the general population. Complications following piercing procedures are variable. Objective, To present an unusual complication after lower lip piercing , embedding of a stud into the lip , and to determine why it occurred from the side of the mucous membrane and not from the side of the skin. Methods, A 21-year-old man presented to the plastic surgery outpatient clinic with embedding of piercing into the lower lip. Results, In lateral X-ray film, a metallic shadow was observed in the area of the oral soft tissues. The length of the stick was only 8 mm. In this patient, a stick that was too short in relation to the thickness of the lip was used. In this situation, the ends of the stud pressed too strongly on the surrounding tissues. Consequently, this may have caused necrosis of the mucous membrane and embedding of the stud into the lip. Conclusion, The observations described confirm a higher susceptibility to mechanical pressure of the mucous membrane than of the skin. An increasing rate of complications after body piercing reflects a lack of medical knowledge in individuals performing such procedures. [source]

Ulhas Patil
Abstract BACKGROUND: Microbial proteases are becoming imperative for commercial applications. The protease secreted by Pseudomonas aeruginosa MTCC 7926, isolated from solvent-contaminated habitat was purified and characterized for activity at various edaphic conditions. The purified alkaline protease was investigated for dehairing of animal skin, anti-staphylococcal activity and processing of X-ray film. RESULTS: The protease was 24-fold purified by ammonium sulfate fractionation, sephadex G-100 gel filtration and DEAE-cellulose, with 36% recovery. KM and Vmax, using casein were 2.94 mg mL,1 and 1.27 µmole min,1, respectively. The apparent molecular mass by SDS-PAGE was 35 kDa. Alkaline protease was active at pH 6,11 and temperature 25,65 °C. Its activity was (a) 86.8% in 100 mmol L,1 NaCl, (b) >95% in metal ions (Mn2+, Ca2+, Mg2+, Fe2+) for 1 h, (c) >90% in bleaching agents and chemical surfactants, (d) 135.4 ± 2.0% and 119.9 ± 6.2% with rhamnolipid and cyclodextrin, respectively, (e) stable in solvents for 5,30 days at 27 °C, and (f) inhibited by EDTA, indicating metalloprotein. CONCLUSION: This work showed that purified protease retained its activity in surfactants, solvents, metals, and bleaching agents. The enzyme is an alternative for detergent formulations, dehairing of animal skin, X-ray film processing, treatment of staphylococcal infections and possibly non-aqueous enzymatic peptide synthesis.

CLINICAL USEFULNESS OF COLONOSCOPIC INSERTION OF A DECOMPRESSION TUBE FOR OBSTRUCTIVE COLORECTAL CANCER

DIGESTIVE ENDOSCOPY, Issue 2004
Kiyonori Kobayashi
ABSTRACT We evaluated the clinical usefulness of colonoscopic insertion of a decompression tube (decompression method) for the treatment of ileus associated with left-sided colorectal cancer. Decompression method was done in 48 patients with colorectal cancer (38 primary cancer, 10 metastatic cancer). A decompression tube was successfully inserted in all but 10 patients who had primary cancer with severe strictures. The overall insertion rate was 79%. Decompression method improved obstructive symptoms and decreased intestinal gas as evaluated on plain X-ray films of the abdomen. Emergency operation was unnecessary in 96% of the patients with primary cancers, in whom the decompression tube was successfully inserted. We conclude that decompression method can improve abdominal symptoms caused by obstructive colorectal cancer and reduce the need for emergency operation. [source]


Multicentric giant cell tumours in an adolescent with haemophilia

HAEMOPHILIA, Issue 2 2007
C.-C. CHANG
Summary., ,,Multicentric giant cell tumour (GCTs) of the extremity is prone to be distributed over the age range of 20,40 years, but is rare in haemophilia and in the age before 20. We report a case of a 15-year-old haemophilia boy who presented initially with two radiolucent loci in the right femur and tibia revealed from the X-ray films and then another lesion in the posterior femoral shaft shown from MRI by one year. Differential diagnosis of GCTs should be appraised in various aspects. Radiological diagnostic pitfall was avoided by the pathology disclosed GCTs without malignancy. The early diagnosis of GCTs in haemophilia may be delayed unless appearance of symptoms of pathologic fracture. Coincident multicentric GCTs do occur in haemophilic patients and their incidence might be underestimated, as it might not be judged because immediate symptoms of pain would resolve with appropriate factor replacement."

Comparative radiopacity of tetracalcium phosphate and other root-end filling materials

INTERNATIONAL ENDODONTIC JOURNAL, Issue 4 2000
C. D. Laghios
Abstract Aim This study compared the radiopacity of tetracalcium phosphate (TTCP) and 11 root-end filling materials relative to human dentine. Methodology Specimens of 2 mm thickness and a graduated aluminium stepwedge were placed on dental X-ray films and exposed to an X-ray beam. The optical densities of the specimens and aluminium steps were measured. The optical densities of the specimens were correlated to the equivalent thickness of aluminium with a regression analysis equation. The equation was used to calculate the equivalent aluminium thickness of each of the specimens. Results Nine of the materials were found to be of acceptable radiopacity (at least 2 mm Al more radiopaque than dentine). TCCP and two of the glass-ionomer compounds were found to have insufficient radiopacity to be radiographically distinguishable from human dentine. Conclusions All the materials were found to be distinguishable radiographically from dentine, except for Vitrebond, TTCP and Ketac-Fil. Amalgam was the most radiopaque material and Ketac-Fil was the least radiopaque material tested. [source]


Delayed immune-mediated adverse effects related to hyaluronic acid and acrylic hydrogel dermal fillers: clinical findings, long-term follow-up and review of the literature

JOURNAL OF THE EUROPEAN ACADEMY OF DERMATOLOGY & VENEREOLOGY, Issue 2 2008
J Alijotas-Reig
Abstract Introduction Implantation of dermal filler for cosmetic purposes is becoming increasingly common worldwide. It is thought that hyaluronic acid (HA) alone or combined with acrylic hydrogels (HA-AH) does not have severe nor persistent side-effects. However, recent evidence may show that major, local and/or systemic, immediate or delayed adverse effects may appear in relation with its use. Objective To evaluate the clinical complaints, laboratory data, treatment and follow-up of patients with delayed adverse effects related to HA and HA-AH implant fillers. Design Prospective, case-series study of patients filled with HA and HA-AH compounds. Setting The study has been done in a tertiary, teaching university hospital. Patients We report on a series of 25 patients, 15 of them in prospective manner, with severe, delayed side-effects related to HA-AH. Inclusion criteria have been drawn up. Patients with immediate side-effects were excluded. Patients were submitted to a clinical follow-up, battery of blood tests and thorax X-ray films. Besides, a review of the literature was made. We undertook a computed-assisted (MEDLINE), National Library of Medicine, Bethesda, MD, USA, search of the literature from 1996 up to December 2005. Main outcome Clinical evaluation of granulomas, skin manifestations and other local and systemic immune-mediated disorders possibly related to HA and HA-AH fillers or their cumulative interaction with previously administered fillers. Results Of 25 cases, 16 were filled with HA alone and 9 with a HA-AH compounds. Of 15 cases analysed and with long-term follow-up, 10 were filled with HA alone, and the remaining five were filled with a HA-AH. Time latency average up to beginning of symptoms was 13.7 months. Three of these 15 cases had been filled before with silicone and another one with Artecoll. Tender nodules were seen in 14 patients. Systemic manifestations appeared in three cases. Laboratory abnormalities were noted in all studied cases. After 16-month average follow-up, seven patients seem to be cured, and six have recurrent bouts. Two cases were lost during follow-up. Conclusion Although in some cases, these clinical complications might have been associated with previous fillers or with other unknown foreign bodies, we feel that, although infrequently, delayed and recurrent chronic inflammatory and granulomatous reactions may complicate HA and HA-AH implant fillers.

Role of Biphosphonates and Lymphatic Drainage Type Leduc in the Complex Regional Pain Syndrome (Shoulder,Hand Syndrome)

PAIN MEDICINE, Issue 1 2009
Andrea Santamato MD
ABSTRACT Background., Complex regional pain syndrome (CRPS) is a clinical entity that has been termed in numerous ways in the last years. Clinically, CRPS describes an array of painful conditions that are characterized by a continuing (spontaneous and/or evoked) regional pain that is seemingly disproportionate in time or degree to the usual course of any known trauma or other lesion. The pain is regional and usually has a distal predominance of abnormal sensory, motor, sudomotor, vasomotor, and/or trophic findings. Design., Case report. Setting., University Medical Center. Patients., In this report, we described the case of a 68-year-old hemiplegic female affected by cerebrovascular accident that presented a clinical case of CRPS shoulder,hand syndrome (CRPS-SHS) at the right hand after a hemorrhagic stroke. Interventions., This report evaluated the effects of biphosphonates and lymphatic drainage type Leduc in CRPS-SHS. Outcome Measures., The pain level of the patients was measured with the visual analog scale. A scoring system for the clinical severity of CRPS-SHS, laboratory tests, and X-ray films were also performed. Results., We reported in this patient a great improvement of pain and edema of the right hand, with a significant reduction of bone demineralization. Conclusions., This combined treatment may be a viable alternative for this syndrome; however, further investigation is needed to determine its reproducibility in large case series. [source]


Two new radiological findings to improve the diagnosis of bronchial foreign-body aspiration in children

PEDIATRIC PULMONOLOGY, Issue 3 2004
Guido Girardi MD
Abstract Our objective was to report on two new chest X-ray signs (hyperinflation or obstructive emphysema with atelectasis in the same hemithorax, and aeration within an area of atelectasis) in children with foreign-body aspiration (FBA). We performed a retrospective review of clinical characteristics and chest X-ray films of 133 children with FBA. Of 133 children, 45% were under 3 years old. History of a choking crisis was present in 101 (75.8%); however, it was only elicited upon follow-up questioning in 33 children (32.7%). Early foreign-body (FB) extraction (<24 hr) was performed in 17.3%; removal took place between 1,7 days in 29.3%. The site of aspirated FBs was bronchial in 78.9%, laryngeal in 6%, and tracheal in 4.5%, with mobile FB in the trachea/bronchi in 4.5%. The chest X-ray was normal in 11.3%. Positive findings included: radiopaque FB (23.3%); hyperinflation or obstructive emphysema (21.8%); hyperinflation or obstructive emphysema with atelectasis in the same hemithorax (18%); lobar atelectasis (12.8%); whole-lung atelectasis (6.8%); shift of mediastinal shadow (11%); and aeration within an area of atelectasis (6%). In conclusion, if a history of choking crisis is not present in a child with suspected FBA, two previously undescribed radiological signs (hyperinflation or obstructive emphysema with atelectasis in the same hemithorax, and aeration within an area of atelectasis) should be sought in order to improve the utility of chest-X ray for early diagnosis of FBA. © 2004 Wiley-Liss, Inc.

Comparison of 1- and 2-Marker Techniques for Calculating System Magnification Factor for Angiographic Measurement of Intracranial Vessels

JOURNAL OF NEUROIMAGING, Issue 4 2005
A. A. Divani PhD
ABSTRACT Background and Purpose. Accurate estimation of an intracranial vessel size is crucial during a diagnostic or therapeutic angiography procedure. The use of 1 or 2 external markers of known size is previously proposed to manually estimate the magnification factor (MF) of an intracranial vessel. The authors evaluated the use of different external marker techniques commonly used during angiographic measurements. Methods. Forty-three intracranial vessels in 17 patients were measured using 1-and 2-marker techniques. To obtain the MF, 2 metallic markers were attached to the frontal-temporal regions. The MFs for the targeted vessels were obtained from the x-ray films by measuring the image sizes of the markers and their positions with respect to the target vessel. Results. Using a phantom, the errors resulted from (a) linear interpolation of MFs, (b) linear interpolation of inverse MFs, and (c) using the MFs of 1 marker, which were 1.23% to 2.23%, 0.8% to 1.55%, and 3.85% to 14.62%, respectively. A similar trend was observed for the measurement of cerebral arteries. Conclusion. The use of 2 markers can result in a more accurate estimation of the vessel size. The use of only 1 external marker can lead to substantial error based on the location of the target vessel. Optimizing image acquisition is also crucial for accurate determination of vessel size.

Kaposi sarcoma of the musculoskeletal system

CANCER, Issue 6 2007
A review of 66 patients
Abstract Kaposi sarcoma (KS) of bone and skeletal muscle is unusual. In this report, the authors review 66 published patients with KS who had involvement of the musculoskeletal system reported from 1925 to 2006. In only 3 patients was acquired immunodeficiency syndrome (AIDS)-related KS identified within skeletal muscle. Osseous KS lesions were more frequent and occurred with African, classic, and AIDS-related KS and occurred rarely in transplantation-associated KS. Patients seldom were asymptomatic. They usually had bone pain with limited mobility or infrequently developed serious sequelae like spinal cord compression. Locally aggressive African and classic KS lesions typically involved the peripheral skeleton; whereas, in patients with AIDS, the axial (vertebrae, ribs, sternum, and pelvis) and/or maxillofacial bones more commonly were involved. Almost all patients had concomitant nonosseous KS lesions. Joint involvement was exceptional, and pathologic fractures were not observed. Computed tomography scans and magnetic resonance images were better at detecting osseous KS lesions, which frequently went undetected on plain x-ray films or bone scans. Pathologic diagnosis was important to exclude similar lesions like bacillary angiomatosis. Treatment options, including surgery and, in more recent patients, radiation and/or chemotherapy, had limited success. Cancer 2007 © 2007 American Cancer Society. [source]
