Diminished concentrations of insulin-like growth factor I in cystic fibrosis

Cystic fibrosis is frequently accompanied by a catabolic condition with low body mass index caused by a number of disease complications. Insulin-like growth factor-I (IGF-I) is an anabolic hormone and an important marker of nutritional status, liver function, and linear growth. Available data on IGF-I in cystic fibrosis are sparse and conflicting. From 1990-3, 235 of our 240 patients (114 males, 121 females, median age 16.2 years, ranged 0.1-44.0 years) had IGF-I measured once by radioimmunoassay. IGF-I was significantly reduced compared with a healthy Scandinavian control population: mean (-2 SD to +2 SD) IGF-I SD score was -0.97 (-3.7 to 1.7) in males and -0.67 (-3.2 to 1.9) in females. Height SD score was -0.95 (-3.3 to 1.4) in males and -0.81 (-3.2 to 1.6) in females. In patients who were still in the growth period a significant correlation of IGF-I SD score to height SD score (r = 0.28, p < 0.001) was found. The low IGF-I concentrations may reflect the catabolic state of many patients with cystic fibrosis and play a part in their abnormal growth pattern.     

Prevalence of bruxism awareness in a Sardinian population

1014 subjects on the island of Sardinia (Italy) were interviewed regarding the habit of clenching and grinding their teeth. They had to specify if this activity occurred during the day, during the night, or both. Other information recorded was their age, gender, marital status, and occupation. Overall prevalence of bruxism was 27.2% (276 subjects). No association was found between bruxism and age, gender and job. Even differentiating diurnal, nocturnal, diurnal and nocturnal bruxism, associations were non-significant. Marital status seems to make some difference: divorced people reported higher parafunctional activity compared to widows and widowers who reported the least. Although awareness of bruxism is not a precise measure of parafunction, based on the results we cannot support the role of stress on bruxism etiology.     

Foot and mouth disease (FMD): serological investigation in some farms of Alexandria Governorate of Egypt

Suspected cases of Foot and Mouth disease (FMD) in cattle were noted in some farms of Alexandria governorate during the period from January to March 2000. The investigated cattle suffered from oral and foot lesions associated with lameness in addition to fever in some and inappetance in others. At the same time the contact workers and veterinarian suffered from fever, during the course of the disease in cattle. Blood samples were withdrawal from suspected cases of cattle (31 cases), and from 24 contact cases. Saliva and vesicular lesions of the tongue were taken on glycerol buffer saline for isolation and serotyping of FMD virus by hyperimmune sera. The virus was isolated from all saliva and vesicular lesions of the diseased animals and serotyped as FMD O1. A total of 30 (96.77%) out of 31 suspected cases, while it was only 10 (41.67%) out of 24 contact cases were positive by ELISA for anti-FMD antibodies. Also 25 blood samples were withdrawal from contact persons with diseased animals and were suffered from fever, while 25 blood samples were taken from contact persons but not suffered from fever while 5 blood samples were taken from persons were not in contact with any veterinary source (Children) and were used as negative control. A total of 13 (52%) out of 25 and 2 (8%) out of 25 were positive for anti-FMD antibodies from diseased and contact persons respectively.     

One hundred and eleven cases of breast conservation treatment with simultaneous reconstruction at the European Institute of Oncology (Milan)

AIMS AND BACKGROUND: Breast conserving treatment (BCT) should provide similar quality of local control as mastectomy and avoid psychological distress due to mutilation. Randomized trials have demonstrated the value of conservative surgery for small tumors. Several publications have indicated the possibility of improving the cosmetic result when quadrantectomy is combined with plastic surgery. These papers focused on two techniques involving reduction mammaplasty and latissimus dorsi flap procedures. At the European Institute of Oncology (EIO) we use various plastic procedures to reshape the breast and to improve symmetry. The choice of these techniques depends on tumor size and location, as well as on breast volume. METHODS AND STUDY DESIGN: In two years (1995 and 1996) 111 patients were treated at the EIO with quadrantectomy and concomitant plastic surgery. Preoperative tumor staging was as follows: T1 57.5%, T2 29%, T3 4.5%, Tis 8%, and sarcoma 1%. The tumor locations were upper quadrant 50%, lower quadrant 40%, and central quadrant 10%. The plastic surgery techniques used included local glandular flaps, areola transposition, mastopexy or classical reduction mastoplasty procedures, the round block technique, prosthesis insertion, and distal musculocutaneous flaps. Cosmetic evaluation on the basis of predefined cosmetic criteria was carried out on photographs after a mean follow-up of 21 months. In 48 cases the patients' own rating of breast cosmesis was asked. RESULTS: The global results were good in 77.5%, fair in 17%, and poor in 5.5% of the patients. No statistical difference was observed between different tumor locations, although the percentage of good cosmetic results, which was similar in the upper and lower quadrantectomy groups, was slightly lower for centrally located tumors. With regard to the different techniques, we obtained 100% good results with the round block technique and the Grisotti flap, 87% good results with the inferior pedicle, 74% good results with the Lejour and superior pedicle techniques, 67% good results with the latissimus dorsi flap, and 58% good results with prosthetic implants. The outcome was less satisfactory when no contralateral mastoplasty was performed (14 of the 111 cases): 72% good, 14% fair, and 14% poor results. These differences were not statistically significant. The median weight of the specimens was 157 g, which is almost three-fold the usual weight in regular tumorectomies. Six carcinomas were found in contralateral breasts (4 DCIS and 2 infiltrating). CONCLUSIONS: The double-team approach (plastic surgeons and oncologists) to BCT may improve the final cosmetic result following large tumor excisions. It can also extend the indications for breast preserving surgery. Moreover, it allows surgical and histological exploration of the contralateral breast when a surgical procedure for symmetry is required.     

Inhibition of 7,12-dimethylbenz[a]anthracene (DMBA)-induced oral carcinogenesis in hamsters by tea and curcumin

Tea is one of the most popular beverages consumed in the world. Curcumin, the major yellow pigment in turmeric, is used widely as a spice and food-coloring agent. In this study, we studied the effects of tea and curcumin on 7,12-dimethylbenz[a]anthracene (DMBA)-induced oral carcinogenesis in hamsters. DMBA solution (0.5% in mineral oil, 0.1 ml) was applied topically to the left cheek pouch of male Syrian golden hamsters 3 times/week for 6 weeks. Two days after the last treatment of DMBA, the animals received green tea (6 mg tea solids/ml) as drinking fluid, or 10 mmol curcumin applied topically 3 times/week, or the combination of green tea and curcumin treatment, or no treatment for 18 weeks. The combination of tea and curcumin significantly decreased the oral visible tumor incidence from 92.3% (24/26) to 69.2% (18/26) and the squamous cell carcinoma (SCC) incidence from 76.9% (20/26) to 42.3% (11/26). The combination of tea and curcumin also decreased the number of visible tumors and the tumor volume by 52.4 and 69.8%, as well as the numbers of SCC, dysplasic lesions and papillomas by 62.0, 37.5 and 48.7%, respectively. Green tea or curcumin treatment decreased the number of visible tumors by 35.1 or 39.6%, the tumor volume by 41.6 or 61.3% and the number of SCC by 53.3 or 51.3%, respectively. Green tea also decreased the number of dysplasic lesions. Curcumin also significantly decreased the SCC incidence. Tea and curcumin, singly or in combination, decreased the proliferation index in hyperplasia, dysplasia and papillomas. Only the combination treatment decreased the proliferation index in SCC. Tea alone and in combination with curcumin significantly increased the apoptotic index in dysplasia and SCC. Curcumin, alone and in combination with tea, significantly inhibited the angiogenesis in papilloma and SCC. The results suggested that green tea and curcumin had inhibitory effects against oral carcinogenesis at the post-initiation stage and such inhibition may be related to the suppression of cell proliferation, induction of apoptosis and inhibition of angiogenesis.     

Atypical lipomatous tumors of the face: a controversial issue

We reviewed the topic of atypical lipomatous tumors including definition, diagnosis and management, with special emphasis on head and neck location and to report on the management of a rare case located in the temporalis muscle. Atypical lipomatous tumors/well-differentiated liposarcomas (ALT/WDLS) are rarely reported in the head and neck. Their behavior dictates a complete resection. Resection with a safety margin is sometimes needed according to the histological characteristics. Tumors located to the masticator space can be accessed through a mucosal approach achieving relative safety to the facial nerve. ALT constitute a group of tumors of a borderline behavior. Their management can be affected by some histological criteria and by their location in the head and neck region where vital structures can be affected.     

Hemicrania continua is not that rare

BACKGROUND: Hemicrania continua is an indomethacin-responsive headache disorder characterized by a continuous, moderate to severe, unilateral headache. More than 90 cases of hemicrania continua have been reported, but there is still uncertainty about its clinical features. METHODS: The authors compared 34 new cases (24 women, 10 men) with previously reported cases. All the patients met Goadsby and Lipton's proposed criteria. The authors compared baseline (continuous background headache) and exacerbation (attacks of severe periods of headaches). RESULTS: The baseline headache was typically mild to moderate in intensity and usually not associated with severe disability. In contrast, the headache exacerbations were severe and associated with photophobia, phonophobia, nausea, and disability. At least one autonomic symptom was present in 25 patients (74%). Jabs and jolts were present in 14 patients (41%). The mean indomethacin dose was 136.7 +/- 60 mg (range 25 to 225 mg). Twenty-four patients (70.6%) met International Headache Society criteria for migraine in their exacerbation period. Occipital tenderness was observed in 23 patients (67.6%). The temporal pattern was remitting in four patients (11.8%), continuous from onset in 18 (52.9%), and continuous evolving from remitting in 12 (35.3%). CONCLUSION: Hemicrania continua is not a rare disorder. All cases of chronic unilateral daily headaches should receive an indomethacin trial early if not first in treatment.
