- Tobacco use is considered to increase the risk of tumor induction. The purpose of this case-controlled investigation was to assess the association of tobacco habits and development of squamous cell carcinoma of the lower lip. Sixty-one patients treated for lower lip cancer, aged between 42 and 90 years, were studied. Age- and sex-matched healthy controls showed a similar exposure to tobacco in years and a comparable distribution of tobacco habits. Although the mean exposure factor (duration times exposure) was greater in the tumor group, no intimate correlation between lip cancer and tobacco was demonstrated. However, an increased, although small, occurrence of herpes labialis lesions was found in cancer patients. The hypothesis is presented that smokers experiencing recurrent herpes simplex virus 1 (HSV-1) infections are more liable to tumor initiation, which issue will be subjected to a future study.

HIGH-SPIN STUDIES NEAR SN-100 WITH NORDBALL - NEW RESULTS ON IN-102, IN-104 AND SB-108
- 1993
-
Konferensbidrag (refereegranskat)abstract
- The NORDBALL detector array has been used in a gamma-ray spectroscopic study of neutron deficient nuclei close to 100Sn. A beam of 270 MeV 58Ni ions was used to bombard a target of Fe-54. Reaction channel separation was achieved with a 4pi charged particle Si-ball together with a 1pi neutron detector wall. Altogether 29 final nuclei were identified and excited states were observed for the first time in 8 of them. The weakest identified channel was 100Cd which represented 4.10(-3) % of the observed total yield. Level schemes Of 102In, 104In and 108Sb constructed from gamma-gamma-particle-coincidence and gamma-gamma-angular correlation analyses are presented. The observed structures are discussed in the framework of the nuclear shell-model. In 108Sb also a deformed, strongly coupled, level sequence is observed. This deformed structure is interpreted as built on a pig9/2(-1)xnuh11/2 configuration in agreement with TRS calculations.

- Neutron deficient nuclei close to 100Sn have been investigated in-beam by gamma-ray spectroscopic methods using the NORDBALL detector array. A beam of 270 MeV Ni-58 was used to bombard a target of Fe-54. Reaction channel separation was achieved with a 4pi charged particle multi-detector set-up together with a 1pi neutron detector wall placed in the forward direction. Excited states of 102In were identified for the first time. The level scheme constructed from gamma-gamma-particle-coincidence and gamma-gamma-angular correlation analysis is presented. The structure of 102In is discussed and compared to neighboring nuclei in the framework of the nuclear shell-model.

- Neutron deficient nuclei close to Sn-100 have been investigated in-beam using the NORDBALL detector array. A target of Fe-54 was bombarded with a beam of Ni-58 at 270 MeV. Evaporation residues were identified by detecting protons and alpha particles in a 4 pi charged particle multi-detector set-up and neutrons in a 1 pi neutron detector wall in coincidence with gamma rays. Excited states of the proton drip line nucleus Sb-106 and of Sb-107 were identified for the first time. The yrast level schemes constructed from gamma-gamma-particle coincidence and gamma-gamma angular correlation analysis are presented and discussed within the framework of the nuclear shell model.

Skin expansion. Long term follow up of complications and costs of care.
- 1993

Tidskriftsartikel (refereegranskat)abstract
- To find out our rate of complications after tissue expansion, and the cost of treatment in terms of use of hospital resources and length of sick leave, we analysed our experience of 181 expansion treatments in 97 patients undertaken between 1986 and 1991. There were 60 women and 37 men, with a mean age of 22 (range 1-74). Twenty patients had more than one period of treatment (range 2-8). The most common conditions treated were naevi (n = 75); scars (trauma--n = 33, burns--n = 17, and operations--n = 16); and breasts that required reconstruction (n = 15). Of the 181 expansions there were 29 failures (16%), and 117 complete successes (64%); fifteen of the latter developed minor complications (8%), 35 were partly successful (20%). There were 77 complications in 71 treatments (38%), and 45 expanders (25%) had to be removed prematurely because of complications. The most common complications were skin penetration (n = 15), minor infection (n = 13), and breakdown of the surgical wound (n = 13). The median (range) inpatient hospital stay was 8 days (2-39); number of visits to the outpatient clinic for filling 7 days (0-20); and total treatment time/patient 82 (19-286). We conclude that skin expansion is a useful technique, but that there is room for improvement in reducing the rate of complications and the amount of time that patients spend being treated.
