Let G be a finite p-group and let d(G) denote the cardinality of a minimal generating set of G. G is said to be d-maximal if d(H) < d(G) for any proper subgroup H of G. In this paper we show that if G is a d-maximal p-group where p is odd, then G has exponent p or p2. For p = 2, we show that under certain conditions, a d-maximal 2-group has exponent four. We then give some classes of d-maximal ...

segmental resection and end-to-end anastomosis is the treatment of choice for patients suffering from tracheal stenosis for whom conservative management is not planned. a complication of this procedure is tension-induced anastomotic failure. to prevent this complication, maintaining the neck in full flexion by means of a suture between the chin and upper chest is a traditional approach. we have...

A 45-year-old human immunodeficiency virus (HIV)-positive male from northeastern India presented with fever and cough as well as a 3-month-old ulcer over the chin. On examination, there was a 5 × 5-cm superficial ulcer with a thick adherent crust over the chin ( Figure 1 ). The individual had three papules with central umbilication over the neck and face. He had anemia (hemoglobin = 7.5 g) and ...

Numbness of the chin, an uncommon neurological symptom, was observed in 15 patients with cancer. Thirteen had breast cancer. This symptom usually heralded progressive involvement of the cranial nerves or cerebrum and denoted a poor prognosis in patients with a short `tumourfree interval'. The pathogenesis is commonly related to dural involvement of the Vth cranial nerve at the base of the brain...

A new technique for an extended genioplasty, the mandibular wing osteotomy, is presented step by step. This osteotomy allows correcting the position of the chinprominence, to change the aspect of the divergence in the mandibular angulus and to achieve a lip competence in cases where it is needed. All these movements of the lower border of the mandibula can be performed completely independently ...
