Abstract
Lethal short-limb skeletal dysplasia Al-Gazali type (OMIM %601356) is an ultra-rare disorder previously reported in only three unrelated individuals. The genetic etiology for Al-Gazali skeletal dysplasia has up until now been unknown. Through international collaborative efforts involving seven clinical centers worldwide, a cohort of nine patients with clinical and radiographic features consistent with short-limb skeletal dysplasia Al-Gazali type was collected. The affected individuals presented with moderate intrauterine growth restriction, relative macrocephaly, hypertrichosis, large anterior fontanelle, short neck, short and stiff limbs with small hands and feet, severe brachydactyly, and generalized bone sclerosis with mild platyspondyly. Biallelic disease-causing variants in ADAMTSL2 were detected using massively parallel sequencing (MPS) and Sanger sequencing techniques. Six individuals were compound heterozygous and one individual was homozygous for pathogenic variants in ADAMTSL2. In one of the families pathogenic variants were detected in parental samples only. Overall, this study sheds light on the genetic cause of Al-Gazali skeletal dysplasia and identifies it as a semi-lethal part of the spectrum of ADAMTSL2-related disorders. Furthermore, we highlight the importance of meticulous analysis of the pseudogene region of ADAMTSL2 where disease-causing variants might be located.

Abstract
BACKGROUND Mediastinal germ cell tumors (GCTs) are rare and usually located in anterior mediastinum. We aimed to review clinical and pathological characteristics of these tumors. PROCEDURE Between 1973 and 2011, 24 children with mediastinal GCTs were diagnosed. Hospital files were reviewed for presenting complaints, clinical, radiological and other laboratory data, surgical practices, treatments, and outcomes. RESULTS Median age was 4.5 years (0.2-16) (male/female: 10/14). Most common initial complaints were dyspnea, cough, anorexia/fatigue, fever, and chest pain. Primary tumors were located in anterior mediastinum (n = 22), posterior mediastinum (n = 1), and sternum (n = 1). Thirteen of 24 cases had mature teratomas (54.2%); four (16.7%) endodermal sinus tumor (EST); four (16.7%) immature teratomas; and one (4.2%) each of embryonal carcinoma, teratocarcinoma, and malignant teratoma. Mature teratomas underwent only surgical resection and were under follow-up without disease. Four cases with ESTs received chemotherapy and radiotherapy (n = 3), three underwent surgical resections: three died, one was followed for 284 months in remission. All but one immature teratomas were treated with surgery and all were under follow-up without disease. Two patients with embryonal carcinoma and malignant teratoma didn't undergo surgery; both received chemotherapy and radiotherapy but died with disease. The patient with teratocarcinoma was treated with surgery and chemotherapy but died with disease. CONCLUSIONS No adjuvant therapy is needed for mature teratomas. Immature teratomas must be under close follow-up for recurrences. Prognosis for mediastinal malignant GCTs was poor. These cases need intensive chemotherapies and effective local control measures as surgery -/+ radiotherapy to ensure long-term survival.

Abstract
Xanthoma disseminatum (XD) is a rare normolipemic mucocutaneous xanthomatosis due to the proliferation of non-x histiocytes. Occasional involvement of the upper respiratory system has been reported, but lower respiratory tract involvement is very rare. Here, we present a child with severe involvement of the upper and lower respiratory tract by XD and bronchiectasis in the lower lobes of both lungs. The patient was an 8-year-old boy who was admitted to our hospital because of red-brown papules which developed on the skin and progressive dyspnea. He was diagnosed as having XD by skin biopsy. Physical examination revealed disseminated, numerous yellow-reddish brown papular xanthomas on the forehead and eyelids, around the neck and axillary area, and in the oral cavity and pharynx. He had respiratory distress and clubbing of the fingers. Chest x-rays showed hyperaeration and segmental atelectasis. High-resolution CT of the thorax revealed diffuse thickening of the whole tracheal and bronchial wall, and bronchiectasis in the lower lobes. Flexible fiberoptic bronchoscopy revealed numerous xanthomatous lesions in the nasal cavity, nasopharynx, oropharynx, subglottic area, trachea, bifurcation, both main bronchi, and smaller bronchi. To the best of our knowledge, this is the first report of a child with typical lesions of XD with severe involvement of the lower respiratory tract and bronchiectasis.

Abstract
Spinal muscular atrophy (SMA) is a clinically and genetically heterogeneous disease characterised by loss of motor function and muscle atrophy due to anterior horn cell degeneration. The most common variant is chromosome 5-linked proximal SMA, ranging in severity from congenital onset and infantile death to onset in adult life. Genetically separate variants with different distribution of weakness and/or additional features such as central nervous system involvement have been described. A rare variant with associated myoclonic epilepsy and lower motor neuron disease had been previously described in three families before the SMN gene, responsible for the common form of SMA, was isolated. We report four patients from two additional families affected by a syndrome characterised by severe and progressive myoclonic epilepsy and proximal weakness, tremor and lower motor neuron disease proven by electrophysiologic and muscle biopsy findings. Extensive metabolic investigations were normal and genetic analysis excluded the SMN gene. This study confirms that the association of myoclonic epilepsy and motor neuron disease represents a separate clinical and genetic entity from chromosome 5-linked SMA, the primary defect of which remains unknown.

Abstract
Visceroatrial situs, ventricular morphology, and atrioventricular and ventriculoarterial alignments can reliably be assessed with fetal echocardiography. We herein describe, to our knowledge, the first reported fetal echocardiographic diagnosis of a fetus with visceroatrial situs solitus, atrioventricular alignment discordance, double outlet right ventricle, and superoinferior ventricles of a 22-year-old gravida III para II woman with a previous history of intrauterine fetal death. She had been evaluated at another center and was referred to our unit because of the suspicion about her diagnosis and underwent fetal ultrasonographic evaluation at 39 weeks gestation. Neonatal echocardiographic evaluation and autopsy findings confirmed the diagnosis. Accordingly there was (solitus, L-loop ventricle, and anterior aorta) double outlet right ventricle, superoinferior ventricles with diminutive right ventricle, noncommitted trabecular ventricular septal defect, and pulmonary hypertension.

Abstract
Giant cell pneumonia is a rare and uncommon type of lung infection developing as a complication of measles, especially in immunocompromised patients, whether their immune systems are affected primarily or whether they have acquired immune defects. As well as being uncommon, it is also atypical because of absence of the characteristic rash and of absent or low antibody titers against measles in most of the cases. It is known that cellular immunity is more important than humoral immunity in the host response to measles, so hypogammaglobulinemic patients with normal cellular immunity usually recover uneventfully from measles and also have the characteristic rash. We report a case with giant cell pneumonia that was confirmed by postmortem histopathological examination. We especially want to point out that even in the absence of rash, with the clinical and radiological features of pneumonia, measles should be considered in a patient, whether in remission or not, receiving immunosuppressive treatment.

Abstract
Ligneous conjunctivitis (LC) is a rare disorder characterized by a chronic course of recurrent membranous lesions at conjunctivae. Pseudomembranes of other mucous membranes have been reported in patients with LC, but to the best of our knowledge, no case with alveolar involvement has been described. Here, we report a 2.5-year-old girl with LC who had tracheoaveolar involvement and homozygous type I plasminogen deficiency. Tracheal involvement was diagnosed by bronchoscopic biopsy and alveolar involvement with postmortem biopsy. She was shown to be homozygous for frameshift mutation in plasminogen exon 14 (Gly565ins-G) with molecular genetic examination of DNA which was obtained from parafin embedded postmortem lung tissue. Ligneous inflammation of the upper and lower respiratory tract must be considered in children with LC and recurrent respiratory tract problems.

Abstract
AIM It has been hypothesized that the cremaster muscle (CM) might play a part in the pathogenesis of various inguinoscrotal pathologies such as undescended testis and hernia. A prospective study was carried out to determine if CM of boys with hydrocele, inguinal hernia, and undescended testis reveal any histopathological and immunohistopathological alterations. METHODS Samples of CM from 29 patients presenting with inguinal hernia (15), undescended testis (9), and hydrocele (5), and CM from autopsies of boys without inguinal pathology (2), and samples of internal oblique muscles from patients undergoing laparotomy (3) were obtained. The biopsies were frozen in isopentane-cooled liquid nitrogen, cut in 6 micron sections and stored at -80 degrees C until processed. Sections were stained by hematoxylin-eosin, modified Gomori-trichrome, PAS, Oil Red-O, NADH, SDH and COX. All specimens were evaluated for seven parameters including variation in fibre size, presence of central nucleus, endomysial fibrosis, inflammation, presence of basophilic fibres, increase in perimysial connective tissue, and variation in fibre size between fascicules. The specimens were also evaluated for beta-spectrin, laminin alpha-1 chain, laminin alpha-2 chain, 43 kd distroglycan, and fetal myosin by immunofluorescence. The presence of each parameter was compared, individually and in combination, according to the ages and underlying pathologies. RESULTS None of the internal oblique muscles were positive for any of the seven parameters. Only one of the two CM obtained during autopsy revealed a slight variation in fibre size. However, fibre size variation and increase in perimysial connective tissue were found in all but one CM from a patient with hernia. The presence or absence of parameters did not differ according to age. Comparison of the groups with inguinal hernia and undescended testis for each of the individual parameters did not reveal significant differences. However, the presence of four or more parameters in each CM was more commonly encountered among patients with undescended testis compared to patients with hernia (p < 0.05). The CM of patients with hydrocele suggested similar findings to patients with inguinal hernia. All of the specimens, regardless of origin, revealed normal sarcolemmal and basal laminal stainings, and fetal myosin was expressed in only two specimens which were obtained from an internal oblique muscle and the CM of a patient with an inguinal hernia. CONCLUSION The CM of patients with inguinal hernia, hydrocele, and undescended testis reveal histopathological alterations. Furthermore, CM from patients with undescended testis reveal more profound alterations. Whether these alterations reflect a primary muscle pathology or a defect in innervation or changes secondary to inguinoscrotal pathology requires further study.

Abstract
Limb-girdle muscular dystrophies constitute a broad range of clinical and genetic entities. We have evaluated 38 autosomal recessive limb-girdle muscular dystrophy (LGMD2) families by linkage analysis for the known loci of LGMD2A-F and protein studies using immunofluorescence and western blotting of the sarcoglycan complex. One index case in each family was investigated thoroughly. The age of onset and the current ages were between 11/2 and 15 years and 6 and 36 years, respectively. The classification of families was as follows: calpainopathy 7, dysferlinopathy 3, alpha sarcoglycan deficiency 2, beta sarcoglycan deficiency 7, gamma sarcoglycan deficiency 5, delta sarcoglycan deficiency 1, and merosinopathy 2. There were two families showing an Emery-Dreifuss phenotype and nine showing no linkage to the LGMD2A-F loci, and they had preserved sarcoglycans. gamma sarcoglycan deficiency seems to be the most severe group as a whole, whereas dysferlinopathy is the mildest. Interfamilial variation was not uncommon. Cardiomyopathy was not present in any of the families. In sarcoglycan deficiencies, sarcoglycans other than the primary ones may also be considerably reduced; however, this may not be reflected in the phenotype. Many cases of primary gamma sarcoglycan deficiency showed normal or only mildly abnormal delta sarcoglycan staining.

Abstract
Polyarteritis nodosa (PAN) is a vasculitis of small- and medium-sized muscular arteries with deposition of immune complex in the vessel wall. Although gastrointestinal involvement is common, the symptomatic involvement of the hepatobiliary system is rare. An eight-year old female patient with a previous diagnosis of familial Mediterranean fever (FMF) was hospitalized for right upper quadrant pain and fever. The thickened gall bladder wall by ultrasonography, called for exploration. Histopathological evaluations of the liver biopsy and gall bladder revealed PAN. Corticosteroid therapy was initiated and the patient recovered fully. This case represents one of the rarest forms of PAN in childhood.

Abstract
An 11-month-old girl with a prolonged history of bloody, mucoid diarrhea is presented. Although the initial diagnosis given by the rectosigmoid biopsy obtained during laparotomy was neuronal intestinal dysplasia, accompanying findings including mixed inflammatory cell infiltration of the mucosa and submucosa with mucosal ulcerations suggested nonspecific colitis. The subsequent biopsy specimen that was obtained after performing colostomy and treating with broad-spectrum antibiotics and rectal irrigations showed improvement in the structure of ganglion cells and submucous and myenteric plexuses. Although the mucosal ulcerations and inflammatory reaction improved, the colonic stricture persisted, so the Duhamel procedure was performed, and the patient had an uneventful outcome. It is claimed that inflammatory disease of the rectosigmoid colon of unknown etiology and neuronal intestinal dysplasia have occurred together in the current case or that one disease might cause the other in time.

Abstract
The clinical features of merosin-positive congenital muscular dystrophy (CMD) and merosin-deficient CMD are well known, with those of merosin-deficient CMD being more severe. Whether the severity of histopathological findings correlates with these clinical features remains unanswered. In this study, the clinical and histopathological findings of 39 merosin-deficient and 37 merosin-positive CMD patients were compared. Merosin-deficient CMD patients were found to be younger, with earlier onset of symptoms, age of diagnosis, and a more severe clinical state (reflecting maximum motor capacity and contractures). On histopathological evaluation, endomysial fibrosis, perimysial fibrosis, and histopathological state (reflecting fibrosis, adiposis, necrosis, and variation in fiber size) were more severe in merosin-deficient CMD. There was a correlation between clinical and histopathological states only in merosin-deficient CMD.

Abstract
We report unusual MR serial imaging and electron microscopy findings in a 3-year-old boy who had Leigh syndrome with cytochrome-c oxidase (cox) deficiency. The MR imaging findings included periventricular white matter involvement, posteroanterior progression, and extension through the corpus callosum and internal capsule; however, no basal ganglia or brain stem abnormality was found, which was suggestive of leukodystrophy. The most noteworthy findings were the cystic foci with contrast enhancement in the affected white matter.

Abstract
Intussusception is one of the most common causes of bowel obstruction in infancy which may require surgical treatment. We have recently recognized a pathologically weakened linear area located on the wall of the reduced colon at operation. Thus, a retrospective study was conducted to evaluate the operative and pathological findings of the resected bowel segments for the treatment of intussusception. A pathologically weakened longitudinal linear area was encountered in five patients. This line was strikingly antimesenteric and under the taenia libera. The bowel wall was very thin and effaced on palpation along this whitish line and showed mucosal necrosis, disruption of the muscularis mucosa, and loss of some of the muscular tissue on microscopic examination. The line may result from compression of the inner layers of the bowel wall between the intussusceptum and the noncompliant taenia. Location on the antimesenteric border and under the taenia libera can be explained by local vascular compromise due to the distribution of the terminal arteries of the colon. Thus, the antimesenteric border as well as the mesenteric side should be checked carefully for a longitudinal weakened pressure line. The recognition of such a potentially dangerous weak line on the bowel wall indicates resection.

Abstract
Ectopic gastric mucosa in the upper esophagus has been reported previously in neonatal autopsy series and encountered in adult esophagoscopies. Despite the usual asymptomatic course of the disease, symptomatic adults have been reported. However there is no report of a symptomatic child with ectopic gastric mucosa in the literature. A 12-year-old boy presenting with dysphagia due to strictures resulting from circular patches of ectopic gastric mucosa located in the mid esophagus is reported.

Abstract
Because they are frequently malignant, swellings of the chest wall during infancy are alarming lesions. Sternal osteomyelitis is a rare condition that may present with a chest wall mass locating in the parasternal region. A parasternal mass of granulomatous osteomyelitic origin is an extremely rare cause with only few case being reported to date. Herein, the authors report on 2 infants presenting with parasternal masses of sternal granulomatous osteomyelitic origin and discuss the possible etiologic role of the bacillus Calmette-Guérin vaccine.

Abstract
The authors report an unusual presentation of inflammatory pseudotumor (IPT) that caused intestinal obstruction in a 9-year-old boy, and discuss the clinicopathologic features of this rare entity with emphasis on diagnosis and treatment. There are no specific presumptive clinical and laboratory findings, including tumor markers and imaging techniques, that distinguish mesenteric IPT from other abdominal mass lesions. The most important diagnostic aid is to bear this entity in mind when a child presents with intestinal obstruction associated with an abdominal mass. Radical unnecessary surgical procedures or potentially harmful therapy should be avoided, and appropriate treatment is achieved by total excision of the lesion in most of the cases.

Abstract
SETTING More than five different primer pairs have been used for the detection of Mycobacterium tuberculosis deoxyribonucleic acid (DNA) with the polymerase chain reaction (PCR). OBJECTIVE The sensitivity and specificity of PCR were evaluated using three different primer pairs in the detection of M. tuberculosis in paraffin-embedded tissues. DESIGN Thirty-eight tissue specimens from 23 patients were studied. Eighteen samples were obtained from 10 tuberculosis patients, and 20 samples obtained from 13 patients with other diseases were used as negative controls. DNA extracted from paraffin-embedded tissues was used directly for PCR amplification using primers IS1 and IS2 to amplify a 123 base pair (bp) region of IS6110, sjMT3 and sjMTr2 to amplify a 281 bp region of protein antigen b, and INS1 and INS2 to amplify a 245 bp region of IS986. Each amplification was performed double-blinded and repeated three times including positive and negative control samples. RESULTS IS1 and IS2 gave a positive result in each of the double samples obtained from eight tuberculosis patients and in the single samples obtained in the two others, sjMT3 and sjMTr2 detected 13 of the 18 tuberculosis samples, and INS1 and INS2 detected only three of the 18. CONCLUSION These results highlight the importance of selecting appropriate primers to obtain high sensitivity in detecting M. tuberculosis in paraffin-embedded tissues by PCR.

Abstract
A 14-year-old girl presented with a 3-month history of easy fatigue and exercise intolerance, especially when climbing stairs. She had a mild ptosis and mild limitation of upward gaze. Her puberty was delayed, and she manifested hypogonadotrophic hypogonadism. Serum lactic and pyruvic acids were elevated. Cranial magnetic resonance imaging was normal. Muscle biopsy documented typical ragged-red fibers. A point mutation at nucleotide 3243 in the tRNALeu(UUR) (typical mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) mutation) was detected in mitochondrial DNA from both blood and muscle tissues, indicating that our patient was suffering from a mitochondrial myopathy. Hypogonadism may be a manifestation of the MELAS nucleotide 3243 mutation.

Abstract
Among our 20 families with LGMD2, 10 were documented to have muscle-specific calcium-activated neutral protease 3 (calpain-3) deficiency. Consanguinity was present in all. The current ages of the index cases were between 12 and 23 years, and there were additional nine members affected. Clinically, the patients showed mild courses; none of the cases below age 30 lost autonomy so far. The dystrophy is mainly proximal and atrophic with calf enlargement and scapular wasting in some. In three cases walking was delayed. Creatine kinase levels were at least 10 times elevated. All obligate carriers had normal creatine kinase levels. Five families shared the same 551 delA frameshift mutation. In four of these families there was the same core haplotype, whereas one was distinct suggesting an independent origin. Calpain-3 deficiency in general is a mild muscular dystrophy during childhood.

Abstract
Autosomal recessive limb girdle muscular dystrophy (LGMD2) is a clinically and genetically heterogenous group of diseases involving at least six different loci. Five genes have already been identified: calpain-3 at LGMD2A (15q15), and four members of the sarcoglycan (SG) complex, alpha-SG at LGMD2D (17q21), beta-SG at LGMD2E (4q12), gamma-SG at LGMD2C (13q12), and delta-SG at LGMD2F (5q33-q34). The gene product at LGMD2B (2p13-p16) is still unknown and at least one other gene is still unmapped. We investigated 20 Turkish families (18 consanguineous) diagnosed as having LGMD2. Most of our patients had onset of symptoms before age 10. The phenotypes varied from severe to benign. We analyzed the SG complex by immunofluorescence and/or western blot. Genotyping was performed using markers defining the six known loci and the suspected genes were screened for mutations. Six of 17 index cases showed deficiency of the SG complex, by immunofluorescence and/or western blot. Seven cases involved one of the known genes of the SG complex (alpha, 2; beta, 1; and gamma, 4 cases), and five mutations were documented in the alpha- and gamma-SG genes. After linkage analysis, 10 families were characterized as having LGMD2A (calpain-3 deficiency), and all mutations were eventually identified. One family was classified as having LGMD2B and 1 family that has normal SGs was linked to the chromosome 5q33-q34 locus (LGMD2F). In 1 family there was no linkage to any of the known LGMD2 loci. It appears that in Turkey, there is a broad spectrum of genes and defects involved in LGMD2. It may be possible to correlate genotype to phenotype in LGMD2. All severe cases belonged to the gamma-SG-deficiency group. Nine calpain-3-deficient cases had intermediate and 1 had moderate clinical courses. The LGMD2B patient had a moderate clinical expression, whereas the LGMD2F case was truly benign.

Abstract
We describe a two-year-old girl who presented with coma following an upper respiratory tract infection. Nonketotic hypoglycemia, metabolic acidosis and mild hyperammonemia were detected. The urinary organic acid profile was consistent with glutaric aciduria type II. Pancreatitis was diagnosed at autopsy. Although pancreatitis has been described in a number of inborn errors of metabolism including organic acidemias, to the best of our knowledge this is the first report of acute pancreatitis occurring in glutaric acidemia type II. It was stressed, therefore, that this complication should be searched for in organic aciduria patients, and the measurement of plasma amylase and lipase levels should be added to the battery of laboratory investigations in such cases.

Abstract
Merosin-positive congenital muscular dystrophy is a heterogenous group of disorders with varying clinical presentations and severity. In general, central nervous system involvement is not present. There is also evidence for still unclassified forms. Here we report three cases in two families with merosin-positive congenital muscular dystrophy, mild mental retardation, bilateral cataracts and normal cranial magnetic resonance imaging. To our knowledge, such an association has not been reported previously, and thus is a new entity within congenital muscular dystrophy nosology.

Abstract
Muscle cell tumors are very uncommon in the spleen as they are in ataxia-telangiectasia. The increased frequency of chromosome breaks probably because of a defect in DNA repair favors the development of benign or malignant tumors in the patient. A case of leiomyoma of the spleen in an 8-year-old boy with ataxia-telangiectasia is reported. The literature on the splenic masses and the localization of leiomyoma is reviewed.

Abstract
Primary, malignant, cardiac tumors are extremely rare in infants and children. Only a few cases of cardiac rhabdomyosarcoma have been reported in childhood. Echocardiography greatly increases the rate of correct diagnosis of cardiac tumors. There are some cases in the literature which were diagnosed by echocardiography and confirmed histopathologically. In this report, a 13-year-old girl with the clinical findings of cardiac tamponade and who was diagnosed as having a cardiac tumor by two-dimensional echocardiogram is presented An echodense, solid tumor with irregular borders extending especially toward the left ventricular cavity from the apex was demonstrated on echocardiography. The diagnosis was confirmed histopathologically on postmortem examination.
