Gerbilliscus kempii
French: Gerbille de Kemp / German: Kemp-Nacktsohlenrennmaus / Spanish: Gerbillo de sabana septentrional
Other common names: Kemp's Gerbil
Taxonomy. Tatera kempii Wroughton, 1906,
Aguleri, Nigeria.
Originally described in genus 7 Tatera, G. kempii was synonymized with G. validus by P. J. J. Bates in 1988 on basis of molar morphology. New chromosomal data allowed G. G. Musser and M. D. Carleton to reinstate kempii as a distinct species in 2005. Molecularstudies by L.. Granjon and colleagues in 2012 confirmed that status and found G. kempui to be sister taxon of G. gambianus. Monotypic.
Distribution. Sub-Saharan regions (Sahelo-Sudanian and Guinean savannas) from Guinea and Sierra Leone E to SW Ethiopia, Uganda, W Kenya, NE DR Congo, Rwanda, Burundi, and NW Tanzania.
Descriptive notes. Head-body 140-190 mm, tail 142-173 mm, ear 17-26 mm, hindfoot 27-36 mm; weight 97-105 g. No sexual dimorphism except fortail length, which is longer in males than in females. A medium-sized gerbil, the Northern Savanna Gerbil has sandy-gray to orange dorsal pelage and pure white venter. Tail is about same length as or slightly longer than body (100% of head—body length) and hasa discrete small pencil at end. Females bear four pairs of mammae. Chromosomal complement has 2n = 48, FNa = 64.
Habitat. Northern Savanna Gerbils prefer grasslands or dense shrubs in sandy and soft soil of savannas. They may be found in anthropogenic habitats such as maize and cassava fields, and in palm oil or cocoa plantations.
Food and Feeding. The Northern Savanna Gerbil is a granivorous, herbivorous rodent. It consumes seeds, roots, leaves, and shoots and may store these in burrows.
Breeding. Reproduction can occur throughout the year. Litter size in Ivory Coast is 2-6.
Activity patterns. The Northern Savanna Gerbil is nocturnal and terrestrial, and digs burrows.
Movements, Home range and Social organization. Locally abundant (up to 45 ind/ha in Nigeria), the Northern Savanna Gerbil may be a social species with overlapping home ranges.
Status and Conservation. Classified as Least Concern on The IUCN Red List (as G. kempi). There are no major threats to this species.

description: Background: Kimura's disease (KD) is a rare, chronic inflammatory disorder with a benign course and an unclear cause. It primarily affects the head and neck regions. KD is often misdiagnosed due to its resemblance to other benign or malignant diseases, especially when it occurs in uncommon sites. In this report, we present a rare case of KD diagnosed in the stomach.

Methods: We report a case of KD localized in the stomach, diagnosed at the Pathology Department of Sahloul University Hospital in Sousse. A 75-year-old female presented with intestinal bleeding. Endoscopy revealed erythematous and hemorrhagic mucosa in the antral and fundic regions of the stomach. A 4 cm antral polyp was identified and subsequently resected.

Results: Initial examination of the biopsy specimen concluded with a diagnosis of a low-grade dysplastic polyp. Partial gastrectomy was performed. Histologically, the polyp was bordered by focally ulcerated epithelium without evidence of dysplasia. The axis was edematous, containing clusters of lymphoid cells dispersed within a moderate inflammatory infiltrate rich in eosinophils. Characteristic multinucleated cells with crown-arranged nuclei were observed. The lesion was well vascularized. Immunohistochemistry for CD117, Dog-1, S100 protein, SMA, and ALK was performed to exclude other diagnoses. The results were negative. After multidisciplinary consultation and expert opinion, a diagnosis of KD was established.

Conclusion: The stomach is an extremely rare localization for KD. Misdiagnosis can result in unnecessary aggressive treatments, making it essential to distinguish KD from other diseases. While KD generally has a good prognosis with no risk of malignant transformation, its high recurrence rate necessitates careful and ongoing monitoring of affected patients.

description: Introduction: Acromegaly is a rare endocrine disorder characterized by excessive growth hormone (GH) secretion, primarily caused by pituitary adenomas. If untreated, it leads to significant morbidity and increased mortality. This study investigates the clinical characteristics and treatment outcomes of acromegaly patients in a Tunisian University Hospital.

Methods: We conducted a retrospective review of medical records for patients diagnosed with acromegaly in the Endocrinology Department of a University Hospital in Central Tunisia over 20 years. Data on clinical features, imaging, comorbidities, and treatment outcomes were collected and analyzed.

Results: Among 41 patients included, the mean age at diagnosis was 37±11 years. MRI revealed macroadenomas in 93.9% of cases, with 58% displaying invasiveness. Adenomas co-secreting GH and prolactin were larger (35 mm vs. 21 mm; p=0.031) and more invasive (80% vs. 23%; p=0.02) compared to GH-only adenomas. Diabetes mellitus was the most common comorbidity (43%), and affected patients were older (42 vs. 34 years; p=0.03). Surgical treatment, primarily via the transsphenoidal route, was performed in 78% of patients. Medical therapy, including somatostatin analogs and dopamine agonists, was administered to 48%, with Lanreotide being the most frequently used agent. Multimodal therapy achieved a cure rate of 29%.

Conclusion: Despite therapeutic advances, managing acromegaly remains challenging. Early diagnosis and individualized treatment strategies are essential to improve patient outcomes.

description: Introduction: Entero-biliary fistula is a rare and difficult-to-diagnose complication of cholelithiasis. While spontaneous evacuation may occur with small stones, surgical intervention is required in most cases. This condition presents significant challenges for the surgeon, as complete clearance of the digestive tract, along with cholecystectomy, may be fraught with difficulty. In this case, we report an instance of intestinal perforation caused by a migrating gallstone.

Case Presentation: An 80-year-old woman presented to our surgery department with abdominal pain. Several diagnostic modalities were employed to reach a definitive diagnosis. Abdominal ultrasound confirmed the diagnosis of acute cholecystitis. The patient underwent urgent surgery after brief resuscitation. During exploration of the abdominal cavity, a punctiform perforation of an intestinal loop was identified. Upon bidigital palpation, a mass was felt that rolled over the fingers. The patient underwent segmental resection, double stoma creation, and feeding jejunostomy. A 2 cm gallstone was expressed from the specimen.

Discussion: One of the rare complications of cholelithiasis is the development of an entero-biliary fistula. Small bowel perforation caused by a migrating gallstone is considered uncommon. The surgical challenge lies in managing both the perforation and the causative fistula, as cholecystectomy itself can be risky. Thorough examination of the small intestine during surgery is crucial to check for any additional intraluminal stones.

Conclusion: Despite its rare prevalence and atypical presentations, a high index of suspicion for entero-biliary fistula is essential, particularly in patients with risk factors. With prompt diagnosis and timely intervention, patients can successfully recover from this clinical condition.

description: Urtica urens is classified within the Rosales subfamily and belongs to the Urticaceae family. Its well-documented health benefits are primarily attributed to its phenolic compounds. This study investigates the polyphenol, flavonoid, and condensed tannin content of Urtica urens L. (U. urens L.) extracts obtained using aqueous ethanol and water as solvents. The antifungal activity of ethanol and aqueous extracts derived from the aerial parts of Urtica urens L. was assessed in vitro against various Candida species (C. parapsilosis, C. albicans, C. tropicalis, C. metapsilosis, C. orthopsilosis, C. glabrata). Three methods were employed: the well diffusion method, disc diffusion method, and microdilution method. The findings revealed that the ethanol extract contained the highest levels of polyphenols. Both ethanol and aqueous extracts exhibited antifungal activity against the Candida strains tested. However, the aqueous extract demonstrated superior antifungal efficacy compared to the ethanol extract. The sensitivity of the strains to the extracts was concentration-dependent, with inhibition observed from a concentration of 1 g/mL. The ethanol extract displayed significant inhibitory activity (90.58%, 92.24%, and 91.33%, respectively) against C. metapsilosis, C. glabrata, and C. orthopsilosis, surpassing its activity against other strains. These findings suggested that U. urens L. extracts have potential as natural alternatives to chemical additives for controlling fungal diseases in plants.

description: Background: Hydatic cyst is a zoonosis that is endemic in developing countries. The most frequent complication of a hydatic liver cyst is communication with the biliary tract. Communication with the duodenum is an uncommon complication.

Case presentation: A 60-year-old woman presented with abdominal pain and vomiting. There was no jaundice or fever. A biological inflammatory syndrome was identified. An abdominal computed tomography (CT) scan revealed a fistula between a centro-hepatic hydatid cyst and the first portion of the duodenum. The subject underwent disconnection of the fistula and a pericystectomy, followed by placement of a tube duodenostomy for the fistula and a subhepatic drain. The postoperative period was uneventful.

Conclusion: Despite the benign nature of hydatic cysts, duodenal fistula is a unusual complication. Surgical treatment is determined by the size of the duodenal defect.

description: The representation of mobility in literary narratives has important
implications for the cultural understanding of human movement and migration.
In this paper, we introduce novel methods for measuring the physical mobility
of literary characters through narrative space and time. We capture mobility
through geographically defined space, as well as through generic locations
such as homes, driveways, and forests. Using a dataset of over 13,000 books
published in English since 1789, we observe significant “small world” effects
in fictional narratives. Specifically, we find that fictional characters cover far
less distance than their nonfictional counterparts; the pathways covered by
fictional characters are highly formulaic and limited from a global perspective;
and fiction exhibits a distinctive semantic investment in domestic and private
places. Surprisingly, we do not find that characters’ ascribed gender has a
statistically significant effect on distance traveled, but it does influence the
semantics of domesticity.

Black-tailed Gerbil
Gerbilliscus nigricaudus
French: Gerbille a queue noire / German: Schwarzschwanz-Nacktsohlenrennmaus / Spanish: Gerbillo de cola negra
Taxonomy. Gerbillus nigricaudus Peters, 1878,
Ndi, Taita, Kenya.
Although morphologically very close to G. robustus, G. nigricaudus was treated as a valid species by P. J. J. Bates in 1985 and 1988 and by I. Ya. Pavlinov and colleagues in 1990. Chromosomes were described by P. Colangelo and coworkers in 2005. A morphometric analysis by P. Colangelo and team in 2010 showed that G. nigricaudus, G. robustus, and G. vicinus are clearly distinct. Further molecular analysis by L. Granjon and colleagues in 2012 suggested that G. nigricaudus belongs to an East African clade that includes also G. robustus, G. phillipsi, and G. vicinus. Two subspecies recognized.
Subspecies and Distribution.
G.n.nigricaudusPeters,1878—SKenyaandNETanzania.
G. n. nyama Dollman, 1911 — SW Ethiopia, SW Somalia, and N Kenya.
Descriptive notes. Head—body 130-193 mm, tail 170-208 mm, ear 20-24 mm, hindfoot 34-41 mm; weight 80-195 g. Females are smaller than males. The Black-tailed Gerbil is characterized by its long black tail (110% of head-body length). Specimens of nominate subspecies nigricaudus are larger and the tail is black above and below, whereas nyama are smaller and the tail not fully black below. This large gerbil has a brown dorsal pelage and a white venter. Chromosomal complement has 2n = 36, FN = 68.
Habitat. Open woodlands and bush thickets in Somali-Masai savannas, as well as open grasslands, at up to elevations of 1500 m.
Food and Feeding. The Black-tailed Gerbil is omnivorous, with seasonal change in diet composition. In dry season, insects can represent up to 90% of diet, supplemented with some seeds and forbs, while in wet season proportion of vegetable matter increases to up to 50%.
Breeding. Although females can reproduce all year, there are two peaks associated with the two wet seasons per year (November—January, April-May). Females bear 1-8 embryos, and mean litter size is 5-5 in wet season and 4-2 in early dry season.
Activity patterns. Black-tailed Gerbils are nocturnal and terrestrial.
Movements, Home range and Social organization. No information.
Status and Conservation. Classified as Least Concern on The IUCN Red List.
