Trisomy 7p: report of 2 patients and literature review

Two patients with a trisomy 7p are reported. Both were assessed by facial dysmorphism and congenital anomalies. In one of the patients trisomy 7p was a de novo event, in the other patient unbalanced inheritance of a parental translocation caused trisomy 7p. Developmental delay was severe in both. Our 2 cases are compared with patients reported in literature.     

Ring chromosome 10: report on two patients and review of the literature

Ring chromosome 10—r(10)—is a rare disorder, with 14 cases reported in the literature, but only two with breakpoint determination by high-resolution techniques. We report here on two patients presenting a ring chromosome 10, studied by G-banding, fluorescent in situ hybridization (FISH), multiplex ligation-dependent probe amplification (MLPA) and SNP-array techniques, in order to investigate ring instability and determine breakpoints. Patient 1 showed a r(10)(p15.3q26.2) with a 7.9 Mb deletion in 10q26.2-q26.2, while patient 2 showed a r(10)(p15.3q26.13) with a 1.0 Mb deletion in 10p15.3 and a 8.8 Mb deletion in 10q26.13-q26.3, both unstable. While patient 1 presented with clinical features usually found in patients with r(10) and terminal 10q deletion, patient 2 presented characteristics so far not described in other patients with r(10), such as Dandy-Walker variant, osteopenia, semi-flexed legs, and dermal pigmentation regions. Our data and the data from literature show that there are no specific clinical findings to define a r(10) syndrome.     

Saksenaea vasiformis infections: Case report and literature review

Since the first human infection by Saksenaea vasiformis in 1976 another 26 cases have been reported. Here is a report of a new case which involved an Ecuadorian adolescent who suffered serious burns after a car accident. It developed as a localized cutaneous infection which was successfully treated with surgical debridement and amphotericin B. This is the second report of this infection from South America and the third involving a burn patient. The previously reported 27 cases are reviewed.     

Cutaneous ciliated cyst: case report and literature review

An 18-year-old girl had a cyst excised from the left buttock in 1988. The cyst was diagnosed to be a cutaneous ciliated cyst, since histologic examination using special stains demonstrated its lining to be similar to fallopian tube epithelium. Only 20 such cases have been published to date, and this report is probably the first case in the plastic surgical literature, to the best of our knowledge.     

Ring chromosome 6: Case report and review of literature

Summary A ring chromosome 6 has been identified by GTG-banding in a male with microcephaly, growth retardation, seizures, epicanthus, hypertelorism, micrognathia, and other congenital anomalies. Cytogenetic studies indicate the instability of the ring chromosome. The most common findings in subjects with ring 6 include: profound to moderate mental retardation, microcephaly, prenatal growth failure, retarded bone age, epicanthal folds, flat nasal bridge, short neck, ears low-set or malformed, microphthalmia, and micrognathia. Linkage studies, including HLA, are consistent with reported maps of chromosome 6.This study was supported in part by grant number 1-442 from the National Foundation — March of Dimes     

Biopercular syndrome: report of two cases and literature review

The anterior opercular or biopercular syndrome is a cortical pseudobulbar palsy due to bilateral lesions of the anterior brain operculum. It is characterized by preservation of reflex function and automatic activity, without mental impairment. Two cases are reported herein and the relevant literature reviewed. The first case was a 73-year-old female with a history of a stroke occurring seven years previously, without sequelae in the interim. She presented with sudden loss of consciousness. The neurological examination showed a right facial central palsy and anarthria, with reflex acts such as smiling, blinking and yawning, not elicited by commands; she also had a right hemiparesis and walking impairment. A brain CT scan showed an old ischemic infarction in the region of the right medial cerebral artery. Because the right motor involvement did not correlate with the findings of the initial CT scan, another CT scan two days later showed an acute brain infarction in the vicinity of the left medial cerebral artery. The second case was an 8-year-old girl with mental retardation and impairment of verbal development, caused by of biopercular pachygyria. Facio-pharyngo-glosso-masticatory diplegia and volitional selective palsy of the oro-facial muscles was seen in both patients. The neuropsychological assessment showed cognitive, emotional and social interaction impairment in both cases -as part of the frontal convexity syndrome in the first case and of mental retardation in the second. The two patients had difficulty in mastication and swallowing. The prognosis for recovery of verbal capacity is poor, although generally most patients recover the ability to swallow.     

Plastic bread-bag clips in the gastrointestinal tract: report of 5 cases and review of the literature

Plastic bread-bag clips have been identified as a cause of local perforation or obstruction at many sites in the gastrointestinal tract. This study is the largest case series yet reported, consisting of 3 cases presenting as small-bowel perforation, 1 case in which the clip was found incidentally in the small bowel at laparotomy during vascular surgery and 1 case in which the clip was found incidentally in the small bowel at autopsy. In all cases there was no radiographic evidence to suggest a foreign body in the gastrointestinal tract. People older than 60 years of age who have either partial or full dentures seem to be particularly at risk for the accidental ingestion of these devices. If accidentally ingested, plastic bread-bag clips represent a significant health hazard. As the population ages, small-bowel perforation secondary to ingestion of such clips may occur with increasing frequency. The authors recommend elimination or redesign of the clips, to prevent their being swallowed and becoming impacted in the small bowel or to allow them to be identified in the gastrointestinal tract by conventional radiography.

Orofacial findings in chronic granulomatous disease: report of twelve patients and review of the literature

Background

Chronic granulomatous disease is an extremely rare primary immunodeficiency syndrome that can be associated with various oral complications. This can affect high number of patients. However, data on oral complications is sparse. Here we will review the literature and describe the orofacial findings in 12 patients.

Findings

The age range was 5-31 years. Oral findings were variable, and reflected a low level of oral hygiene. They included periodontitis, rampant caries, gingivitis, aphthous-like ulcers, and geographic tongue. One patient had white patches on the buccal mucosa similar to lichen planus. Another patient had a nodular dorsum of the tongue associated with fissured and geographic tongue. Biopsies from the latter two lesions revealed chronic non-specific mucositis. Panoramic radiographs showed extensive periodontitis in one patient and periapical lesions in another patient.

Conclusion

Patients with chronic granulomatous disease may develop oral lesions reflecting susceptibility to infections and inflammation. It is also possible that social and genetic factors may influence the development of this complication. Therefore, oral hygiene must be kept at an optimum level to prevent infections that can be difficult to manage.

     

Combined surgical-orthodontic treatment of patients with cleidocranial dysplasia: case report and review of the literature

Objectives

To study the present treatment situation and investigate a better orthodontic approach for patients with cleidocranial dysplasia (CCD) through systematically reviewing the published cases and to conclude the surgical-orthodontic treatment experience of cleidocranial dysplasia.

Methods

A comprehensive search for studies published through to April 10, 2018 was conducted using the Pubmed, Web of Science, and Embase databases. The CCD cases treated with the approach combining surgical exposure and orthodontic treatment were concluded.

Results

Eight papers and 9 finished cases were included to be compared with the present case. The age of cases ranged from 9 to 28?years. Clearing the way of eruption path in early age can facilitate the spontaneous eruption of impacted teeth. For adults, combined surgical-orthodontic treatment can achieve a nearly complete dentition and stable occlusal contact, but it is time consuming and needs surgical assistance. The combination of orthognathic surgery can reduce the difficulty of orthodontic treatment and treatment duration, as well as achieve a better facial profile.

Conclusion

Surgical exposure combined with orthodontic traction is an effective treatment for patient with CCD. Patient’s age, demand, economic circumstances, and status of permanent dentition should be considered when making treatment plan.

     

Hairy cell leukemia associated with carcinoma: report of two patients and review of the literature

The association of carcinoma and hairy cell leukemia (HCL) in two patients is recorded. One of the cases was a 58-year-old male who developed carcinoma of the kidney, while the second patient was a 48-year-old woman with carcinoma in the breast. This rare association is probably coincidental, as it is not described in most of the larger reported series of patients with HCL. It is of interest to note that the first patient had received radiation therapy thirty years before the diagnosis of HCL and carcinoma was made.     

Human pentastomiasis in China: case report and literature review

A 13-yr-old boy was admitted because of persistent fever, abdominal pain and diarrhea for 3 mo. Abdomen CT revealed hepatomegaly and multiple nodular low-density pathological changes. At laparotomy considerable yellow and turbid ascites were seen in the abdominal cavity and miliary nodules were noted on the surface of the omentum majus, liver, and small intestine wall. Histological examination revealed parenchymal tubercles containing several worms. Pathological diagnosis was parasitic granuloma. These parasites were identified as Porocephalus taiwana sp.nov. The patient made an uneventful recovery after therapy and was discharged. Moreover, another 17 cases of human pentastomiasis reported from China were reviewed. Human pentastomiasis is an extremely rare disease and this is only the second case of human Porocephalus taiwana sp.nov infection. Pentastomiasis should be considered in differential diagnosis of patients with a history of abdominal symptoms and eating of poorly-cooked snakes.     

Limb-shaking transient ischemic attacks: case report and review of literature

Background

Parkinson's disease (PD) is the most common neurodegenerative movement disorder, characterized clinically by resting tremor, bradykinesia, postural instability and rigidity. The prevalence of PD is approximately 2% of the population over 65 years of age and 1.7 million PD patients (age ≥ 55 years) live in China. Recently, a common LRRK2 variant Gly2385Arg was reported in ethnic Chinese PD population in Taiwan. We analyzed the frequency of this variant in our independent PD case-control population of Han Chinese from Taiwan.

Methods

305 patients and 176 genetically unrelated healthy controls were examined by neurologists and the diagnosis of PD was based on the published criteria. The region of interest was amplified with standard polymerase chain reaction (PCR). PCR fragments then were directly sequenced in both forward and reverse directions. Differences in genotype frequencies between groups were assessed by the X ² test, while X ² analysis was used to test for the Hardy-Weinberg equilibrium.

Results

Of the 305 patients screened we identified 27 (9%) with heterozygous G2385R variant. This mutation was only found in 1 (0.5%) in our healthy control samples (odds ratio = 16.99, 95% CI: 2.29 to 126.21, p = 0.0002). Sequencing of the entire open reading frame of LRRK2 in G2385R carriers revealed no other variants.

Conclusion

These data suggest that the G2385R variant contributes significantly to the etiology of PD in ethnic Han Chinese individuals. With consideration of the enormous and expanding aging Chinese population in mainland China and in Taiwan, this variant is probably the most common known genetic factor for PD worldwide.     

Nasopharyngeal mucoepidermoid carcinoma: A case report and review of literature

Background

Salivary gland-type tumors originating in the nasopharynx are rare, and only a few articles about mucoepidermoid carcinomas (MEC) in this location have been reported. We describe one case of nasopharyngeal MEC and, based on a review of the literature, discuss different therapeutic approaches that can be taken regarding the result of histological findings, radiological tests and extent of disease.

Case presentation

A 47-year-old woman diagnosed with mucoepidermoid carcinoma of nasopharynx, T1 N3 M0 (stage IV-B) was treated in 2007 with a combination of radiotherapy and chemotherapy to a maximum dose of 70 Gy and concomitant Cisplatin during the radiation. One year later, with the head and neck disease under control, mediastinal nodes relapse appeared which were treated with exclusive radiotherapy to a maximum dose of 65 Gy. One year after the first relapse, a second relapse was detected in the right lung, next to the previously treated mediastinal regions, and the patient initiated a treatment with exclusive chemotherapy based on TPF scheme.

Conclusion

For limited or resectable MEC, combined surgery with radiotherapy, or radiochemotherapy, should be considered the main treatment policy. On the other hand, in poorly differentiated, unresectable tumors or nasopharyngeal MEC, radiochemotherapy could be currently the main treatment approach.     

Limb-shaking transient ischemic attacks: case report and review of literature

Background  

Limb shaking Transient Ischemic Attack is a rare manifestation of carotid-occlusive disease. The symptoms usually point towards a seizure like activity and misdiagnosed as focal seizures. On careful history the rhythmic seizure like activity reveals no Jacksonian march mainly precipitated by maneuvers which lead to carotid compression. We here present a case of an elderly gentleman who was initially worked up as suffering from epileptic discharge and then later on found to have carotid occlusion.

Rhinosporidiosis in Egypt: A case report and review of literature

Rhinosporidiosis is an infection caused by Rhinosporidium seeberi that frequently presents as a polypoidal nasal lesions. Here, we report the first indigenous case of tumoral rhinosporidiosis in Egypt. In this case, a 25-year-old male patient from a rural background of Assuit City presented with epistaxis and a nasal polyp. The patient had not traveled abroad. The diagnosis was established on the morphological basis by the identification of 5- to 10-m endospores and 50- to 1000-m sporangia. The clinicopathological and immunologic features were discussed and the literature was reviewed. To the best of our knowledge this is the first case of this disease to be reported in Egypt in the human literature.
