Sixteen opportunistic field observations of eight species of Brazilian raptors (Falconiformes and Strigiformes) are reported here as a contribution to the knowledge of the natural history of these poorly studied birds in Brazil. The observations are related to the food habits (Buteo albicaudatus, Herpetotheres cachinnans, Milvago chimachima, Falco femoralis), reproduction (Asio stygius, Megascops choliba), mobbing behaviour elicited in other birds (Geranospiza caerulescens, H. cachinnans, F. femoralis, A. stygius, Athene cunicularia) and a rare case of leucism in owls (A. cunicularia).

Ctenus medius Keyserling, 1891 is a common species in several spots of Mata Atlântica, however there is a great lack of studies in all aspects of its natural history. This work aims to elucidate aspects of ecotope preference compared to large spiders, and to provide data on the development of chromatic patterns during its life cycle. The observations on the behavior of C. medius were done in the campus of Centro Universitário de Barra Mansa (UBM) by means of observations and nocturnal collections using cap lamps. For observations on the development of chromatic patterns, spiderlings raised in laboratory, hatched from an oviposition of a female from campus of UBM, and others spiderlings collected in field were used. The field observations indicate that: C. medius seems to prefer ecotopes characterized by dense shrub vegetation or herbal undergrowth; Lycosa erythrognatha and L. nordeskioldii seems to prefer open sites; Phoneutria nigriventer seems to prefer shrub vegetation and anthropogenic ecotopes as rubbish hills; Ancylometes sp. seems to prefer ecotopes near streams. Concerning chromatic patterns, it was observed that males and females show well distinct patterns during the last two instars, allowing distinction by sex without the use of a microscope. Through chromatic patterns it was also possible to draw a distinction between C. medius and C. ornatus longer that 3 mm cephalothorax width. 69 specimens of C. medius (males and females) collected in the campus of UBM did not show a striking polymorphism in chromatic pattern, but one among 7 adult females collected in National Park of Itatiaia, showed a distinct chromatic pattern.

Abstract The following conclusions can be made concerning the cause of anemia in patients with untreated chronic lymphatic leukemia excluding the rare case with an autoimmune hemolytic anemia: 1. Early in the natural history of the disease there is a normal amount of erythroblastic tissue which produces red cells at a normal rate. The rate of red cell destruction is also normal. 2. With progression of the disease the erythroblastic tissue is gradually replaced by lymphatic tissue, leading to a decrease in red cell production. The rate of red cell destruction is still normal. 3. Only late in the disease may decreased rate of red cell production be aggravated by an increased rate of red cell destruction.

Infection by Treponema pallidum still represents a clinical challenge due to its various forms of presentation. HIV coinfection added diversity and changed the natural history of syphilis as a systemic infection. We present a rare case of subacute hypophysitis and panhypopituitarism due to an early active neurosyphilis in a previously unknown HIV coinfected patient.

Ameloblastic carcinoma is a rare type of ameloblastoma that has received little mention in the literature. While a number of cases have been published over many years, no institution has been able to produce a substantial case series. Ameloblastic carcinoma originates in the embryonic tooth components. It is believed to be an aggressive tumor that can metastasize; once metastasis occurs, the prognosis tends to be poor. Ameloblastic carcinoma is primarily a surgical condition that is best treated with resection; there has been little indication that other modalities are helpful. We present the case of a 40-year-old woman who was found to have a mandibular lesion by a dentist. After surgical resection, the tumor was found to be an ameloblastic carcinoma. The patient recovered without complication, and she was recurrence-free 18 months postoperatively. We also briefly review the available literature on the natural history of and management options for this rare tumor.

Diagnostic Pitfalls

A report of a rare case of the spinal hydatidosis in a child is presented. Spinal hydatidosis with a total spinal instability caused by the natural history of the disease and inadequate surgical treatment was diagnosed in a 10 year-old girl. At the department the excision of paravertebral and prevertebral hydatid cavernous masses followed by anterior L1–L5 reconstruction and posterior spinal CD-instrumentation was performed. Early post-op results are satisfactory, supporting ability of the spine is restored, that allowed physical and social rehabilitation of the child. Diagnostic pitfalls are identified and discussed.
