Gliomatosis Cerebri Type 1 Mimicking an Ischemic Stroke and Progressing to a Type 2: a Case Study and Literature Review

ABSTRACT Plio?-Pleistocene outcrops located at the southwestern edge of the Guadalquivir Basin in the area of Lepe (Huelva, Spain) provide an interesting example for studying the contemporaneity of traces with the rocks that contain them. Two different types of cells compatible with the ichnogenera Celliforma (Type 1) and Palmiraichnus (Type 2) were found in these outcrops. Their walls were constructed with the same material as the matrix and our first research in the area showed no extant bees producing them suggesting that they were coeval with the trace-bearing rocks. The case of the “Palmiraichnus-like” Type 2 cells was misleading because of its similarity with Palmiraichnus described from the region in the Canary Islands and Balearic Archipelago (Spain). Two determining features were vital in clarifying this first appearance. In the Palmiraichnus-like cells we found remains of a larval cocoon in one cell that could be dated by C14, giving a modern age. In the Celliforma-like cells more field research in the area allow us to observe extant bees nesting in these rocks in autumn. Ichnological literature show a few cases of asynchronies involving extant traces found mostly in Paleozoic and Mesozoic rocks. In contrast, the case presented herein indicates the time gap between the bearing rocks and the Lepe traces was shorter (ca. 12 ky–2.6 My), enhancing the similarity of traces and rocks and thus their potential coevalness. This case may serve as a warning about other potential examples in the fossil record in which relatively short asynchronies between traces and paleosols exist.

Studies about population immobility, especially immobility associated with climate change-related disaster, are very limited. As a consequence, the explanation of population immobility in disaster prone areas is still blurred. This study contributes in explaining population immobility by exploring the typology of residents who did not move from disaster-prone areas. The survey was conducted towards the residents of Kampung Tambak Lorok Semarang, which is prone to three disasters simultaneously i.e. sea level rise, land subsidence, and tidal inundation. The study sample was 235 heads of households selected using proportional sampling area technique. Data were collected using a questionnaire consisting of two parts: (1) demographic, social, and economic characteristics of people who did not move from disaster prone areas; and (2) staying intention in disaster prone areas. Data analysis used descriptive analysis by using table and graph of respondent characteristic and relation between respondent characteristic and staying intention in research area. Three (3) typologies have been identified, namely: Type-1 are residents who wishes to stay; Type-2 are residents who still have not decided whether to stay or move; and Type-3 are residents who do not want to stay/want to move. Each of these typologies is described by place of birth, age, length of stay, education, occupation, and income. The understanding of the typology of residents living in disaster prone areas is important as inputs for policy-makers, especially regarding the relocation of people from disaster prone areas to be effective. The results of this study also contribute empirical evidence to the migration theory debate at the micro level, namely that the staying intention is a key element in the 'black box' of immobile decision-making from disaster prone areas.

Background and Study Aims Schwannomas are benign tumors derived from the Schwann cells of the peripheral nerve sheath that rarely affect the retroperitoneum. When symptomatic, surgical resection is usually recommended via open surgery or the laparoscopic transperitoneal approach. We discuss the retroperitoneoscopic resection of lumbosacral plexus schwannomas through an illustrative case and literature review. A new management classification is also proposed. Patients A 61-year-old woman affected by schwannomatosis presented with neuropathic pain in her right inguinocrural area for the past 4 years before admission. Preoperative imaging revealed a 2-cm right retroperitoneal tumor lateral to the psoas muscle. The diagnosis of a schwannoma of the ilioinguinal nerve was then suggested. The patient underwent complete tumor resection through retroperitoneoscopy, and no recurrence was observed over the long term. A review of the relevant literature revealed that surgical strategy depends on tumor location, and therefore patients are divided into three groups by tumor position to guide trocar placement: type 1 (paravertebral or over the psoas muscle), type 2 (lateral to the psoas muscle), and type 3 (sacral or pelvic). Results Four patients were classified as type 1, one as type 2, and three as type 3, thereby guiding trocar placement to a lateral, anterior, or inferior montage, respectively. Conclusions Retroperitoneoscopy is a minimally invasive technique that offers some potential advantages in approaching retroperitoneal masses. This new classification is useful to group patients and thus provide guidance on the best retroperitoneoscopic surgical strategy.
