Congenital cytomegalovirus related intestinal malrotation: a case report
2016
Background: Cytomegalovirus is the most common cause of congenital infection in the developed countries. Gastrointestinal involvement has been extensively described in both adult and paediatric immunocompromised patients but it is infrequent in congenital or perinatal CMV infection. Case presentation: We report on a case of coexistent congenital Cytomegalovirus infection with intestinal malrotation and positive intestinal Cytomegalovirus biopsy. At birth the neonate showed clinical and radiological evidence of intestinal obstruction. Meconium passed only after evacuative nursing procedures; stooling pattern was irregular; gastric residuals were bile-stained. Laparatomy revealed a complete i…

Small Bowel Perforations: What the Radiologist Needs to Know
2016
The incidence of small bowel perforation is low but can develop from a variety of causes including Crohn disease, ischemic or bacterial enteritis, diverticulitis, bowel obstruction, volvulus, intussusception, trauma, and ingested foreign bodies. In contrast to gastroduodenal perforation, the amount of extraluminal air in small bowel perforation is small or absent in most cases. This article will illustrate the main aspects of small bowel perforation, focusing on anatomical reasons of radiological findings and in the evaluation of the site of perforation using plain film, ultrasound, and multidetector computed tomography equipments. In particular, the authors highlight the anatomic key notes…
Identification and characterization of onchoastacin, an astacin-like metalloproteinase from the filaria Onchocerca volvulus
2007
Abstract The tissue-invasive nematode Onchocerca volvulus causes skin and eye pathology in human onchocerciasis. While the adult females reside sessile in subcutaneous nodules, the microfilariae are abundantly released from the nodules, males and juvenile worms migrate through the host tissue. Matrix-degrading metallo- and serine proteinases have been detected in excretory-secretory worm products that may be essential for migration of the mobile stages. In this study, a 1713 bp long cDNA encoding for a putative proteinase of O. volvulus has been isolated. The predicted protein sequence includes a signal peptide indicating secretion to the extracellular space, a propeptide, an astacin-like p…
Taxonomy and evolution of the Convolvulus sabatius complex (Convolvulaceae)
2010
A revision of the Convolvulus sabatius complex is presented and five taxa are now recognised. Convolvulus valentinus is re-circumscribed to comprise only blue-flowered individuals. Yellow-flowered plants previously referred to this species are transferred to C. supinus where they are recognised as a distinct variety: C. supinus var. melliflorus, comb nov. Variation in intensity of flower colour, pubescence and leaf shape among blue-flowered C. valentinus is highly variable within populations and in contrast to earlier treatments, no infraspecific taxa based on these traits are recognised. Despite suggestions to the contrary, the delimitation of the cultivated ornamental C. sabatius and its …
Data from: Sympatric diversification vs. immigration: deciphering host-plant specialization in a polyphagous insect, the stolbur phytoplasma vector H…
2013
The epidemiology of vector transmitted plant diseases is highly influenced by dispersal and the host-plant range of the vector. Widening the vector's host range may increase transmission potential, whereas specialization may induce specific disease cycles. The process leading to a vector's host shift and its epidemiological outcome is therefore embedded in the frameworks of sympatric evolution vs. immigration of preadapted populations. In this study, we analyse whether a host shift of the stolbur phytoplasma vector, Hyalesthes obsoletus from field bindweed to stinging nettle in its northern distribution range evolved sympatrically or by immigration. The exploitation of stinging nettle has l…
Clinical case and short review of extreme short bowel syndrome: an update 21 years after
2016
Short bowel syndrome refers to the malabsorptive state caused by loss of significant portions of the small intestine, whose clinical framework is characterized by malnutrition, diarrhea, dehydration, weight loss, and low-weight-related symptoms/signs. These clinical conditions seem to be related to the length of resection. Twenty-one years ago we reported the clinical case of an infant, who underwent a massive resection of the loops of the small intestine, of the cecum and of part of the ascending colon, due to intestinal malrotation with volvulus. The residual small intestine measured just 11 cm and consisted of the duodenum and a small part of jejunum, in the absence of the ileocecal valv…
Small bowel volvulus due to a large intestinal lipoma: A rare case report
2020
Highlights • These are rare, benign, slow-growing mesenchymal tumors originating from adipose tissue in the bowel wall. Lipomas of mesentery, mesocolon, and antimesenteric side of intestine are extremely rare. • We describe a case of small bowel obstruction secondary to volvulus due to an antimesenteric ileal lipoma. • Mesenteric lipomas are rare clinical entity, with less than 50 cases described in English language literature. CT scan is the gold standard imaging modality for diagnosis of mesenteric lipoma and other lipomatous abdominal masses. • It shows homogenous tumor of adipose tissue, gives information about features of the small bowel and if there is evidence of ischemia and can dem…
Small bowel obstruction after caesarean section: Laparoscopic management. Two case reports
2020
Abstract Introduction Caesarean section is the most common abdominal surgery performed on women worldwide. Adhesions represent a severe complication of cesarean section and can cause different degrees of bowel obstruction. Case reports We report two unusual cases of small bowel obstruction treated with laparoscopic approach after caesarean section performed for gynecological pathologies. In the first one small bowel obstruction was due to volvulus caused by a severe pelvic adhesion syndrome; in the second one, occlusive picture was related to presence of multiple adhesion phenomena between the sigmoid colon and the right ovary as result of abdominal hysterectomy. Discussion The incidence of…
Spinal anaesthesia in a patient with post-spine surgery dural ectasia.
2013
Dural sac ectasia is a very infrequent anatomical abnormality, usually caused by connective tissue diseases, as Marfan syndrome. Very few cases have been described being a consequence of a previous spine surgical procedure. We describe the case of an elderly patient who should be operated on twice due to sub-occlusive colon disease. Surgery was performed under spinal anaesthesia. A dural sac ectasia was suspected after the first procedure and the abdominal X-ray was reviewed. The characteristics of the anatomical alteration and the course of both anaesthetic procedures were described. X-ray and CT images were provided.
