Hypertrophied posterior longitudinal ligament and ligamentum flavum causing myelopathy: a case report and literature review.

INTRODUCTION: The occurrence of concurrent hypertrophied posterior longitudinal ligament (HPLL) and hypertrophied ligamentum flavum (HLF) in the thoracic spine is a very rare presentation. This case report describes a young female who developed thoracic myelopathy secondary to a combination of both thoracic HPLL and HLF. CASE PRESENTATION: A 30-year-old previously well female was referred for an MRI scan of the thoraco-lumbar spine. She was having lower limb weakness and difficulty in walking, which had progressed over 3 months. On examination, she was found to have spastic lower limbs with associated motor weakness. Her biochemical investigations were unremarkable. The MRI scan showed HPLL, which was uniformly hypointense on T2W images and was isointense on T1W images. The hypertrophied segment was extending from T2 level to T7 level. Similarly, the ligamentum flavum was hypertrophied from T1 level to T8 level. The thoracic spinal cord was seen compressed between the hypertrophied ligaments. The compressed cord showed central hyperintense signal pattern in T2W images. CT scan of the thoracic spine did not show any calcifications or ossifications along the ligaments. Patient underwent posterior decompressive surgery and she had an uneventful recovery. DISCUSSION: Although few cases of HPLL and HLF were reported in older patients in literature, both these conditions were found in this patient at a younger age. HPLL and HLF are thought to be precursors of ossification of these ligaments and these patients need long-term follow-up.

Portal Venous and Mesenteric Wall Calcifications along with Intra-splenic Vascular Calcification: A Rare Case Report and Literature Review.

BACKGROUND: Cross-sectional imaging findings of portal vein calcification were found to be an indicator of portal vein thrombosis. Calcification of the portal vein and its tributaries in portal hypertension is an uncommon finding and the mechanical stress due to long-standing portal hypertension on the vessel wall is considered leading to sclerosis and calcification in the intima and media of the vessel wall. Intra-splenic vascular calcification is a rare occurrence and has been seen in patients with portal hypertension. CASE PRESENTATION: A 60-year-old male was referred for an ultrasound scan of the abdomen, as he was found to have mild elevation of liver enzymes during a routine medical investigation. His ultrasound scan showed features of cirrhosis and portal hypertension. Furthermore, there were intra-splenic calcifications with branching pattern. Subsequent CT confirmed intra-splenic vascular calcification and calcifications in the wall of the thrombosed portal vein and its tributaries. CONCLUSION: Pre-operative identification of portal venous calcification is important, as this might adversely affect surgical interventions for cirrhosis and portal hypertension. Furthermore, to our best knowledge, there have not been any cases reported with concurrent calcification of the portal venous system and intra-splenic vascular calcification in association with portal hypertension in literature.

Public health programmes to promote mental health in young people: a systematic integrative review protocol.

INTRODUCTION: In light of the ever-growing mental health disease burden among young people worldwide, we aim to systematically review the global literature to identify the public health programmes targeted at promoting mental health and well-being in young people, the reported/anticipated mental health-related outcomes of the implemented public health programmes and the reported facilitators and barriers in relation to the implementation of those public health programmes. METHODS AND ANALYSIS: A comprehensive literature search will be carried out in the following electronic bibliographic databases: MEDLINE, EMBASE, PsycINFO, Scopus, ASSIA, Web of Science, Global Health, AMED, Health Source and The Cochrane Library. Further, a manual search of the reference lists of eligible studies and reviews will be carried out. The search strategy will include combinations of three key blocks of terms, namely: 'young people', 'mental health' and 'public health programme', using database-specific subject headings and text words. Two reviewers will independently screen, assess data quality and extract data for synthesis. Disagreements at any stage will be resolved by consensus with the involvement of a third reviewer. Given the anticipated methodological pluralism of the potential eligible studies, we will provide a narrative synthesis of the findings on public health programmes aimed at promoting the mental health and well-being of young people according to identified thematic areas. Furthermore, a narrative synthesis of the reported facilitators and barriers in relation to the implementation of public health programmes will be provided. ETHICS AND DISSEMINATION: Given that the review findings will be focused on understanding the breadth and depth of the global research into public health programmes to promote mental health in young people with a particular emphasis on the facilitators and barriers of programmatic implementation, the findings will be of great value to inform future interventions, programmes and approaches to promote mental health and well-being of young people worldwide.

Gastroduodenal Emphysema with Portal Venous Air due to Congenital Duodenal Web in a Child: A Case Report and Review of Literature.

Congenital duodenal web causing proximal duodenal obstruction leading to gastroduodenal emphysema is a very rare presentation in infancy. Due to persistent peristalsis against the duodenal membrane, there is progressive stretching of the duodenal web leading to windsock deformity. We describe a rare case of a child with gastroduodenal emphysema and portal venous air due to duodenal obstruction secondary to a duodenal web. An eighteen-month-old male child, who was under investigation for failure to thrive, presented with a history of persistent projectile vomiting and progressive abdominal distension for two days. The abdominal ultrasound scan revealed air within the portal vein and in the wall of the stomach. Plain X-ray abdomen confirmed the presence of gas in the gastric wall and in the proximal duodenal wall. Upper gastrointestinal contrast study revealed complete obstruction at the second part of the duodenum. The child underwent emergency laparotomy, which revealed a duodenal web as the cause of the duodenal obstruction. During the surgery, windsock deformity was noted. This case illustrates that although rare, proximal duodenal obstruction due to duodenal web may present in early childhood and that alarming imaging features such as gastric emphysema and portal venous air could be associated with benign conditions.

Diagnostic accuracy of ultrasound characteristics in the identification of malignant thyroid nodules.

OBJECTIVE: This study was aimed at determining the diagnostic accuracy of the ultrasound characteristics in the identification of malignant thyroid nodules in patients attending the surgical clinic at a tertiary care hospital in Sri Lanka. RESULTS: This prospective validation study was conducted among 263 patients attending the surgical clinic at a tertiary care hospital, Sri Lanka. The ultrasound characteristics having statistically significant associations with thyroid malignancies were identified by employing a multivariable analysis. These ultrasound characteristics were compared with Fine Needle Aspiration Cytology results and indicators of diagnostic accuracy were computed. The study sample consisted of 33 malignant and 230 benign nodules. Internal vascularity, hypoechogenicity and microcalcification showed statistically significant positive associations with thyroid malignancy (p < 0.05). The highest positive likelihood ratio was observed for the presence of microcalcifications (10.4, 95% CI 4.6-23.7) with a specificity of 96.5% (95% CI 93.3-98.5%). Hypoechogenicity had a sensitivity of 66.7% (95% CI 48.2-82.0%) and a specificity of 74.8% (95% CI 68.6-80.3%). The presence of at least one positive ultrasound characteristic yielded the highest sensitivity (87.9%, 95% CI 71.8-96.6%), whereas, the presence of all three characteristics yielded a near perfect specificity (99.6%, 95% CI 97.6-99.9%). Hence, the presence of microcalcifications was found to be the single most useful criterion in predicting thyroid malignancy.
