    由于羊膜带综合征的异常表现,新生儿出生时患有独特的先天性下肢畸形。从右脚足底表面到右臀部的异常软组织系带导致膝盖极度屈曲,发育中的足的胫骨旋转和畸形。这种复杂的畸形需要多学科团队(MDT)方法来决定重建和截肢。分娩后73天手术释放组织带,改善膝盖伸展,并将组织堆积在大腿上作为管状椎弓根,以备将来重建。病人接受了康复治疗,这已被证明是至关重要的滑膜关节形成。18个月大的时候,决定进行膝盖截肢和假肢。所讨论的文献表明,在复杂的下肢病例中,MDT方法对于为患者提供最佳功能结果的重要性。
    A neonate was born with a unique congenital lower limb dysmelia due to an abnormal presentation of amniotic band syndrome. An anomalous soft tissue tether from the plantar surface of the right foot to the right buttock caused extreme knee flexion, tibial rotation and malformation of the developing foot. This complex malformation required a multidisciplinary team (MDT) approach to decide between reconstruction and amputation. The band of tissue was released operatively at 73 days postdelivery, improving knee extension, and the tissue was banked on the thigh as a tube pedicle for future reconstruction. The patient underwent rehabilitation, which has been shown to be vital for synovial joint formation. At 18 months old, the decision was made to proceed with through-knee amputation and a prosthesis. The literature discussed shows the importance of an MDT approach in complex lower limb cases to give the best functional outcome for the patient.

    低血糖是新生儿期惊厥的最常见原因之一。必须紧急解决反复的低血糖性惊厥,以防止其病态后遗症。婴儿期反复酮症性低血糖需要详细的内分泌评估。我们的病人是他生命第三年的男孩,在婴儿期出现低血糖性惊厥和皮肤和粘膜色素沉着过度。调查显示酮症性低血糖,低皮质醇血症伴高促肾上腺皮质激素(ACTH)和正常醛固酮,17-羟孕酮(17-OHP)和睾酮水平。这表明孤立的糖皮质激素缺乏而没有盐皮质激素缺乏。他对氢化可的松治疗反应良好,症状缓解,实验室参数正常化。遗传研究证实了家族性糖皮质激素缺乏症(FGD)的诊断,NNT(烟酰胺核苷酸转氨酶)基因具有纯合突变,具有新的p.Thr578lle变体。这是印度次大陆报道的首例具有NNT突变的FGD。
    Hypoglycaemia is one of the most common causes of convulsions in neonatal period. Repeated hypoglycaemic convulsions have to be addressed with utmost urgency to prevent its morbid sequelae. Repeated ketotic hypoglycaemia in the infantile period needs detailed endocrine evaluation. Our patient is a boy in the third year of his life, had presented in infancy with hypoglycaemic convulsions and hyperpigmentation of skin and mucous membrane. Investigations revealed ketotic hypoglycaemia, hypocortisolaemia with high adrenocorticotropic hormone (ACTH) and normal aldosterone, 17-hydroxyprogesterone (17-OHP) and testosterone levels. This suggested isolated glucocorticoid deficiency without mineralocorticoid deficiency. He responded well to hydrocortisone therapy with resolution of symptoms and normalisation of lab parameters. Genetic study confirmed the diagnosis of familial glucocorticoid deficiency (FGD) with homozygous mutation in NNT (nicotinamide nucleotide transhydrogenase) gene with a novel p.Thr578lle variant. This is the first case of FGD with NNT mutation to be reported from the Indian subcontinent.

    一名男性婴儿从3个月大开始出现身体进行性苍白。在检查中,孩子脸色苍白,小头畸形伴畸形相(鼻桥凹陷,低耳朵,回颌,高拱形腭和舌错构瘤)。双侧手和脚的后轴多指,宽阔的大脚趾,左第四脚趾和第五脚趾都有。血象图显示严重贫血,伴有小细胞色素减退。高效液相色谱(HPLC)正常。然而,父母的HPLC提示β地中海贫血特征。全外显子组测序显示Thurston综合征伴β-地中海贫血纯合型有新突变这是一种罕见的遗传综合征,仅在南亚人群中发现。由于稀有,这种综合征的识别通常很困难,需要临床医生的认识。然而,为了向父母提供适当的遗传咨询和预后,准确诊断疾病非常重要。
    A male infant presented with progressive paleness of the body since 3 months of age. On examination, the child had pallor, microcephaly with dysmorphic facies (depressed nasal bridge, low set ears, retrognathia, high arched palate and tongue hamartoma). Postaxial polydactyly in bilateral hands and feet, broad great toes, with syndactyly of left fourth and fifth toes were present. The haemogram showed severe anaemia with a microcytic hypochromic picture. High-performance liquid chromatography (HPLC) was normal. However, the parents\' HPLC was suggestive of beta thalassaemia trait. Whole-exome sequencing revealed Thurston syndrome with beta-thalassaemia in homozygous pattern with a novel mutation. It is a rare genetic syndrome exclusively found in the South Asian population. Due to the rarity, identification of this syndrome is often difficult and requires awareness among clinicians. However, it is important to diagnose the disorder accurately in order to provide appropriate genetic counselling and prognostication to the parents.

    本报告介绍了1例儿童戈谢病1型,这是一种罕见的遗传性代谢紊乱。虽然临床症状是典型的,该病例的组织学检查结果不典型,最初导致诊断不确定.骨髓的病理组织学发现是Gaucher细胞,它们是继发于葡萄糖神经酰胺积累的脂质吞噬的吞噬细胞。使用普鲁士蓝铁染色剂,这些细胞通常表现出弥漫性和强烈的铁染色。在这种情况下,尽管在骨髓上看到的组织细胞异常,骨髓上没有铁染色,因此考虑了大量其他诊断。回想起来,这种异常可能是在长期缺铁和贫血的情况下,由于这种表现的隐蔽性。1型戈谢病的预后良好,与目前的治疗方法显着改善持续时间和生活质量。我们探讨了多学科协作方法在解决诊断不确定性方面的实用性,以及在诊断1型戈谢病以提供适当和有针对性的治疗方面的重要性。
    This report presents a case of childhood Gaucher disease type 1, a rare inherited metabolic disorder. Although the clinical symptoms were classical, the histological findings in this case were atypical and initially led to diagnostic uncertainty. The pathognomonic histological finding on bone marrow is Gaucher cells, which are lipid-engorged phagocytes secondary to the accumulation of glucosylceramide. These cells typically demonstrate diffuse and avid iron staining using a Prussian blue iron stain. In this case, although the histiocytes seen on bone marrow were abnormal, the absence of iron staining on bone marrow led to a large range of other diagnoses being considered. In retrospect, this anomaly was likely in the setting of prolonged iron deficiency and anaemia as a result of the insidious nature of this presentation. The prognosis of type 1 Gaucher disease is favourable, with current treatments significantly improving duration and quality of life. We explore the utility of a collaborative multidisciplinary approach in addressing diagnostic uncertainty and the importance in making a diagnosis for Gaucher disease type 1 in order to provide appropriate and targeted treatment.

    肺隔离症是一种罕见的先天性疾病。它是一种发育不良的肺组织,具有单独的全身血液供应,没有支气管树连接。叠加感染的出现可以导致其诊断,如金黄色葡萄球菌,铜绿假单胞菌,诺卡氏菌小行星和肺炎曲霉。鸟分枝杆菌复合体(MAC)叠加病极为罕见。我们报告了一名男子在他的第三个十年中没有已知的医学疾病表现为持续咳嗽的病例。经过广泛的微生物检查,诊断为MAC感染。还注意到升高的碳水化合物抗原19-9(CA19-9)。他接受了抗分枝杆菌治疗和肺叶切除术,导致临床改善和CA19-9正常化。此病例说明了全面的微生物学检查对患有慢性呼吸道症状和影像学发现的细菌性肺炎患者的价值。仍然需要临床研究来研究CA19-9在评分系统中的实用性以指导MAC治疗。
    Pulmonary sequestration is a rare congenital condition. It is a dysplastic lung tissue with a separate systemic blood supply and without a bronchial tree connection. The emergence of a superimposed infection can lead to its diagnosis, such as Staphylococcus aureus, Pseudomonas aeruginosa, Nocardia asteroids and Aspergillus sp pneumonia. Mycobacterium avium complex (MAC) superimposed disease is exceedingly rare. We report a case of a man in his third decade without known medical disorders presenting with a persistent cough. After an extensive microbiological workup, an MAC infection was diagnosed. An elevated carbohydrate antigen 19-9 (CA 19-9) was also noted. He was treated with antimycobacterial therapy and lobectomy resulting in clinical improvement and CA19-9 normalisation. This case illustrates the value of comprehensive microbiological investigations in patients with chronic respiratory symptoms and imaging findings that are not typical of bacterial pneumonia. Clinical studies remain needed to investigate the utility of CA 19-9 in a scoring system to guide MAC therapy.

    支气管裂隙囊肿通常单侧发生在颈部的外侧。双侧支气管囊肿很少见,可能有家族性联系。我们报告了一例罕见的23岁女性患者的非综合征性双侧支气管囊肿,该患者患有慢性双侧,逐渐扩大无痛的颈部肿胀。完成双侧囊肿的完整手术切除。组织病理学检查证实了诊断。通过早期和完整的手术切除支气管囊肿的精确诊断可能有助于预防复发和其他并发症。
    Branchial cleft cysts generally occur unilaterally at the lateral aspect of the neck. Bilateral branchial cysts are rare and may have familial associations. We report a rare case of non-syndromic bilateral branchial cyst in a 23-year-old woman who presented with chronic bilateral, progressively enlarging painless neck swellings. Complete surgical excision of the bilateral cyst was done. A histopathological examination confirmed the diagnosis. Precise diagnosis with early and complete surgical excision of branchial cysts may help prevent recurrence and other complications.

    编码转录因子的基因突变,包括SOX2在内,与生长激素缺乏(GHD)和垂体发育异常有关。过渡期GHD管理指南指出,基于遗传的儿童期发病GHD患者可以跳过重新测试,因为永久性GHD的可能性很高。我们描述了一例由于SOX2突变而导致的视隔发育不良,其特征是儿童期发作的GHD,在过渡时期表现出正常的促躯体功能。这个案例增加了在过渡期内重新测试GHD的机会,即使是已知遗传原因的患者,以避免不适当的GH治疗。
    Gene mutations encoding transcription factors, including SOX2, have been associated with growth hormone deficiency (GHD) and abnormal pituitary development. Guidelines on GHD management in the transition period state that patients with genetic-based childhood-onset GHD can skip retesting due to a high likelihood of permanent GHD. We describe a case of septo-optic-dysplasia due to SOX2 mutation characterised by childhood-onset GHD, which showed a normal somatotropic function at the transition period. This case raises the opportunity to retest for GHD during the transition period, even in patients with a known genetic cause, in order to avoid inappropriate GH treatment.
