The research involved 67 patients aged 29 - 58 (average age 42) with severe migraine. The examination plan included laboratory diagnostics, assessment of dementia severity (CDR), assessment of cognitive impairment (MMSE), cerebral computed tomography (CT), cerebral magnetic resonance imaging (MRI), cerebral scintigraphy (SG), rheoencephalography (REG), cerebral multi-gated angiography (MUGA). Hypoplasia symptoms were detected in 56 (83.58%) patients. To improve cerebral blood supply, the method of transcateter laser revascularization by means of low-energy CW lasers was used. Good immediate angiographic outcome manifested in persistent improvement of the intracranial vascular bed and marked collateral vascularization was obtained in 53 (94.64%) patients. Good clinical outcome— almost complete regression of migraine and vestibular disorders—was obtained in 49 (87.50%) patients. Satisfactory clinical outcome—partial regression of migraine and vestibular disorders— was observed in 7 (12.50%) patients. The method of transcatheter laser revascularization of cerebral vessels is a physiological, effective and low-invasive treatment for patients suffering from cerebral vessels hypoplasia accompanied by migraine. This method has virtually no alternative;it stimulates natural angiogenesis causing collateral and capillary vascularization steadily improving the blood supply of the brain. The effect obtained after the treatment persists for a long time (9 years and longer), it causes regression of migraine, reduces mental disorders, and can improve the patients’ quality of life.展开更多

Patients and methods: 14 adult cleft lip and palate patients with maxillary hypoplasia were evaluated clinically. Dental models and radiographs including (lateral cephalograms and orthopantographs) were obtained at the initial visit and upon completion of the presurgical orthodontic treatment. Patients with occlusal discrepancies larger than 6 mm and severe palatal scaring underwent Distraction osteogenesis (DO) to advance the maxilla. Patients with an occlusal discrepancy of 6 mm or less, underwent traditional orthognathic surgery including le fort I advancement and Bilateral sagittal split osteotomy (BSSO) to seat the mandible in occlusion. Results: Five patients underwent orthognathic surgery. Two of them underwent double jaw surgery. Three underwent single jaw conventional le fort l advancement. Four patients required bone grafting to repair the residual alveolar defect and to augment the midface deficiency. Nine patients with severe maxillary hypoplasia underwent maxillary advancement using distraction osteogenesis. Conclusion: Patients with a severe maxillary hypoplasia of 6 mm or more and excessive palatal scaring are successfully treated with DO. Conventional le fort I is reserved for patients with less severe maxillary hypoplasia. Both techniques gave promising results providing having followed the proper selection criteria.展开更多

Central brain herniation (CBH) secondary to IAE is rare;it may be a bad prognosis. Here, we presented a 4-year-old girl with influenza who had a pontocerebellar hypoplasia (PCH) history;she performed the second Magnetic Resonance Imaging (MRI) on Day 6 from onset, showed the diffuse edema and the occurrence of central herniation;the medulla was “Z-like” folded and the basal cisterns were obliterated completely. Finally she was declared dead. The imbalance between supratentorial and infratentorial pressure can lead to the occurrence of CBH. Severe edema relates to IAE and unstable structure of the posterior fossa might be the main reason for the herniation. MRI is helpful in early diagnosis. Early treatment of cerebral edema in patients with congenital abnormalities of the posterior fossa is vital for their management.展开更多

Our knowledge about this developmental anomaly is limited and based primarily on case reports. Ovarian hypoplasia is usually asymptomatic;it is most commonly diagnosed from laparoscopy for other indications. Here we report two cases of unilateral ovarian hypoplasia in patients who presented to the Continuum Reproductive Center with primary infertility. After initial infertility workup, both patients underwent diagnostic laparoscopy for suspected tubal disease. In each case, operative findings were consistent with unilateral ovarian hypoplasia. Following the surgery, one patient underwent in vitro fertilization and achieved an ongoing pregnancy. The other conceived spontaneously, but was diagnosed with an ectopic pregnancy.展开更多

The diagnosis requires several exams to eliminate other causes of pulmonary retraction. We report two cases at the department of pneumophtisiology of the University Teaching Hospital of Point G. The first case is a young adult who was complaining of a chronic cough. Etiological investigation required several exams including spirometry and Computed tomographic scan (CT scan). After elimination of all suspected causes of pulmonary opacity, the diagnosis of pulmonary hypoplasia was retained. The second case is a 2-year-old girl who was born with congenital cardiopathy whose respiratory complications were increasing during her childhood and respiratory explorations discovered pulmonary agenesis. Pulmonary hypoplasia is rare in our medical practice, but attention must be drawn to a retractile pulmonary opacity in young age after elimination of all infectious causes in TB endemic area.展开更多

Clinical symptoms vary depending on the other system anomalies and severity of pulmonary hypoplasia. Although it is usually diagnosed in infancy and childhood, some cases do not show any symptoms until the adolescent ages. In adolescents and adults with unilateral hypolucent lung, although it is seen rarely, pulmonary hypoplasia should always be kept in mind. In this article, we present a case with pulmonary hypoplasia who remained asymptomatic until puberty.展开更多

In this report, we present a patient with congenital unilateral upper lip palsy although the facial nerve was normal.展开更多

文摘Several diseases originate from bile duct pathology.Despite studies on these diseases,certain etiologies of some of them still cannot be concluded.The most common disease of the bile duct in newborns is biliary atresia,whose prognosis varies according to the age of surgical correction.Other diseases such as Alagille syndrome,inspissated bile duct syndrome,and choledochal cysts are also time-sensitive because they can cause severe liver damage due to obstruction.The majority of these diseases present with cholestatic jaundice in the newborn or infant period,which is quite difficult to differentiate regarding clinical acumen and initial investigations.Intraoperative cholangiography is potentially necessary to make an accurate diagnosis,and further treatment will be performed synchronously or planned as findings suggest.This article provides a concise review of bile duct diseases,with interesting cases.
