An Uncommon Cause of Hypertensive Urgency in Young Adolescent: Case Report

Mid aortic syndrome is rare cause of hypertensive urgency in children with poor outcome if left untreated, high index of suspicion with prompt management is the key to survival with good outcome. A 12-year-old boy was presented with fever, puffiness of face, and breathing difficulty. Clinically, he had hypertension with differential pulsation and BP in upper and lower limbs. He had peak systolic gradient of 80 mm Hg between upper and lower limb. His echocardiography and CT angiography was suggestive of significant isolated 80% narrowing of abdominal aorta without involvement any other large vessels. Percutaneous balloon dilatation of aorta was done considering multiple parameters. Post procedure, there was significant improvement in BP and we could wean his multiple anti-hypertensive drugs to keep his blood pressures below 95th centile. His BP remained control with minimum upper and lower limb gradient on follow up of almost 1 year.

KEY MESSAGE

Mid aortic syndrome is most uncommon amongst them. With prompt diagnosis and proper selection of therapeutic options like balloon dilatation or surgical correction, it has good prognosis. Aortic narrowing because of different diseases is an uncommon cause of HT urgency in children.

Recurrent Paradoxical Tuberculosis with Chest Wall Abscess and Optochiasmatic Tuberculoma

New-onset clinical or radiological symptoms in a patient with tuberculosis pose diagnostic treatment challenges, which can be due to treatment failure, disease relapse, or paradoxical response. We describe an adolescent case of recurrent paradoxical response complicating tuberculous meningitis. The first paradoxical tuberculosis presented as chest wall abscess, which was complicated by uniocular, gradually progressive, painless loss of vision after 6 months.

Comparison of telephone with face to face consultation for follow up of Neurocysticercosis

OBJECTIVES

There is significant scarcity of specialists to provide care for children with epilepsy in many parts of the world. Telemedicine is a potential future option. This study was planned to estimate the diagnostic accuracy of telephone consultation to identify Critical Clinical Events (breakthrough seizures, drug non-compliance, drug adverse events, features of raised intracranial pressure, and other disease-related events),compared to the Face-to-Face consultation (gold standard), in children with Neurocysticercosis (NCC) and symptomatic seizures, following the completion of cysticidal therapy.

METHODS

Children aged 2-15 years attending a tertiary health care facility with a diagnosis of NCC and symptomatic seizures were enrolled after completion of the cysticidal therapy. The parents were contacted by a Pediatric Neurology Resident on Telephone before the scheduled hospital visit. Subsequently, all the children were seen directly in hospital the next day by another Pediatric Neurology Resident. The information was noted on a structured questionnaire. The diagnostic accuracy of telephone consultation for identifying the Critical Clinical Events was estimated using Face-to-Face consultation as the gold standard.

RESULTS

A total of 1145 potential events were evaluated. Of these, the face-to-face consultation identified 56 events that would need hospital visit for detailed evaluation (breakthrough seizures in 19, drug non-compliance in 15, adverse drug events in 11, features of raised intracranial pressure in 8, and other disease-related events in 3), and 1089 events that did not require hospital consultation. The sensitivity, specificity, positive and negative predictive values of telephone consultation were 89.28% (78.12-95.96), 97.61% (96.52-98.43), 65.79% (54.01-76.30), and 99.43% (98.78-99.79) respectively. The likelihood ratios when telephone consultation was positive and negative were 37.3 and 0.11 respectively.

SIGNIFICANCE

Telephone consultation is an acceptable mode of follow-up for children with mild Neurocysticercosis and symptomatic seizures after completion of cysticidal therapy.

Tunable Twin Matching Frequency (fm1/fm2) Behavior of Ni1-xZnxFe2O4/NBR Composites over 2-12.4 GHz: A Strategic Material System for Stealth Applications

The gel to carbonate precipitate route has been used for the synthesis of Ni_1-xZn_xFe₂O₄ (x = 0, 0.25, 0.5 and 0.75) bulk inverse spinel ferrite powder samples. The optimal zinc (50%) substitution has shown the maximum saturation magnetic moment and resulted into the maximum magnetic loss tangent (tanδ_m) > -1.2 over the entire 2-10 GHz frequency range with an optimum value ~-1.75 at 6 GHz. Ni_0.5Zn_0.5Fe₂O₄- Acrylo-Nitrile Butadiene Rubber (NBR) composite samples are prepared at different weight percentage (wt%) of ferrite loading fractions in rubber for microwave absorption evaluation. The 80 wt% loaded Ni_0.5Zn_0.5Fe₂O₄/NBR composite (FMAR80) sample has shown two reflection loss (RL) peaks at 5 and 10 GHz. Interestingly, a single peak at 10 GHz for 3.25 mm thickness, can be scaled down to 5 GHz by increasing the thickness up to 4.6 mm. The onset of such twin matching frequencies in FMAR80 composite sample is attributed to the spin resonance relaxation at ~5 GHz (f_m1) and destructive interference at λ_m/4 matched thickness near ~10 GHz (f_m2) in these composite systems. These studies suggest the potential of tuning the twin frequencies in Ni_0.5Zn_0.5Fe₂O₄/NBR composite samples for possible microwave absorption applications.

Psychotic symptoms in anti-N-methyl-d-aspartate (NMDA) receptor encephalitis: A case report and challenges

Anti-N-methyl-d-aspartate (NMDA) receptor encephalitis, only recently first described, is an increasingly well-recognized inflammatory encephalitis that is seen in children and adults. An 11-year old girl admitted to the psychiatry ward with a presentation of acute psychosis was diagnosed with NMDA receptor encephalitis following neurology referral and was treated accordingly. This case highlights psychiatric manifestations in encephalitis and the need for the psychiatrist to have high index of suspicion when atypical symptoms (e.g., dyskinesia, seizure, fever etc.) present in acutely psychotic patients.

Bilateral ophthalmoplegia in a child with migraine

BACKGROUND

In children, migraine with or without aura is a common entity, however variants like recurrent painful optic neuropathy (RPON) is rarely encountered.

CASE RESULT

A 9 year old boy presented with headache for 1 week and restricted movements and drooping in both eyes for last 3 days. On examination he had bilateral ophthalmoplegia and ptosis. History of migrainous headache was present in the patient as well as his mother. His MRI brain with venogram, serum autoimmune markers, serum and urine toxicology screen and repetitive nerve stimulation test were normal. He received intravenous pulse followed by oral steroids for 6 weeks and was started on antimigraine prophylaxis. Eighteen months since the attack, he has improved completely with mild asymmetric mydriasis persisting.

DISCUSSION AND CONCLUSION

This may represent first attack of RPON in a child with migraine. Rarely this may herald the onset of migraine as well, index of suspicion should be high as it is a diagnosis of exclusion and a treatable entity.

Recurrent headache in a five year old boy

Headache is infrequent in early childhood. Headache and neurological deficits associated with cerebrospinal fluid (CSF) lymphocytosis (HaNDL), a variant of migraine, is a rare disorder. A 5-year-old boy presented with recurrent episodes of headache for 6 months. Each episode lasted for a week and in the current episode, he was symptomatic for 3 days. All the episodes were associated with paresthesias and CSF lymplocytosis with normal protein and sugar. There was history of migraine in his family. His magnetic resonance imaging (MRI) brain with contrast with magnetic resonance (MR) angiography and venography were normal. Work-up for relevant causes of infection and vasculitis were negative. His symptoms subsided on oral antimigraine prophylaxis and he has been on remission for last 8 months. HaNDL should be considered in relevant clinical scenarios, as it prevents unnecessary investigations, therapy, and hospitalization.

Finger drop sign: Rare presentation of a common disorder

BACKGROUND

Guillain Barre syndrome (GBS) commonly presents with limb weakness and occasional cranial nerve, respiratory or autonomic involvement. Isolated or predominant bilateral finger drop as presenting feature has never been reported in the pediatric age group.

CASE

A 9-year-old boy presented with deformity of both hands for 7 days and leg pain with difficulty in getting up from floor for 3 days. On examination he had bilateral clawing with subtle hip flexor weakness and hyporeflexia. His nerve conduction study revealed motor axonal neuropathy. His serum lead levels and autoimmune markers were within normal limits. His cerebrospinal fluid examination revealed albuminocytological dissociation. He was diagnosed as GBS and was given intravenous immunoglobulin. He improved completely over next 8 weeks.

CONCLUSIONS

GBS is one of the commonest causes of acquired neuropathy in the tropics. In resource limited setting, where electrophysiological facilities may not be available, identification of finger drop sign may help in correct management.

Acquired demyelinating disorders of central nervous system: A pediatric cohort

Objective:

This is a retrospective chart review of consecutive children with acquired demyelinating disorders presenting to a north Indian tertiary care hospital over 4 years. The aim of this review is to describe all the patients (with single event as well as those with recurrences) with detailed description of those who recurred.

Materials and Methods:

Overall 35 cases were reviewed and their clinical presentations, diagnosis, management, and follow-up are being presented.

Results:

Out of 35 cases, 24 did not show any recurrences (seven acute disseminated encephalomyelitis (ADEM) and 17 clinically isolated syndromes). Amongst the 11 patients with recurrent demyelination, majority were multiple sclerosis (8/11, 72.7%) followed by neuromyelitis optica (NMO; 2/11), and multiphasic ADEM (1/11). The median disease duration and follow-up since onset for those with recurrent episodes is 4 years (2.5-4.5 years). Steroids caused significant improvement in acute episodes of demyelination. However, recurrent demyelinating disorders like multiple sclerosis and NMO required long-term immunomodulation. Azathioprine currently is the most favored long-term immunomodulator used in NMO. Interferon-β and glatiramer acetate are currently recommended for multiple sclerosis. However, azathioprine may be a suitable alternative in a resource-limited setting.

Conclusion:

The consensus definitions for these groups of disorders need further validation in the pediatric age group. Studies with larger population size are required to characterize features that predict future recurrences.

A Combination of Moyamoya Pattern and Cerebral Venous Sinus Thrombosis: A Case of Tubercular Vasculopathy

BACKGROUND

Moyamoya vasculopathy, arising secondary to tubercular meningitis (TBM) is unusual. There have also been a few reports of cerebral venous sinus thrombosis (CVST) in TBM. A case of TBM, complicated simultaneously by Moyamoya syndrome and CVST, is being presented here.

CASE

A 1-year-old girl presented with febrile encephalopathy, vomiting, seizures and left hemiparesis. Cerebrospinal fluid analysis was suggestive of TBM. Extensive infarcts were noted in the magnetic resonance imaging, involving right middle cerebral artery (MCA), anterior cerebral artery and the left MCA. Magnetic resonance venogram revealed left transverse venous sinus thrombosis and magnetic resonance angiography showed bilateral moyamoya pattern of arteriopathy. Patient was started on antitubercular therapy and low molecular weight heparin.

CONCLUSIONS

Early vascular involvement affecting both arterial and venous structures has not hitherto been reported in CNS tuberculosis. Early recognition of secondary complications of CNS tuberculosis is crucial to prevent the morbidity and mortality associated with TBM.

A case of congenital myopathy masquerading as paroxysmal dyskinesia

Gastroesophageal reflux (GER) disease is a significant comorbidity of neuromuscular disorders. It may present as paroxysmal dyskinesia, an entity known as Sandifer syndrome. A 6-week-old neonate presented with very frequent paroxysms of generalized stiffening and opisthotonic posture since day 22 of life. These were initially diagnosed as seizures and he was started on multiple antiepileptics which did not show any response. After a normal video electroencephalogram (VEEG) was documented, possibility of dyskinesia was kept. However, when he did not respond to symptomatic therapy, Sandifer syndrome was thought of and GER scan was done, which revealed severe GER. After his symptoms got reduced to some extent, a detailed clinical examination revealed abnormal facies with flaccid quadriparesis. Muscle biopsy confirmed the diagnosis of a specific congenital myopathy. On antireflux measures, those episodic paroxysms reduced to some extent. Partial response to therapy in GER should prompt search for an underlying secondary etiology.

Daily versus alternate day thyroxine therapy to maintain euthyroidism in children with congenital hypothyroidism

BACKGROUND

Daily administration of thyroxine has proven efficacy in treatment of children with hypothyroidism. However, the possibility of treatment with longer dosing intervals that offers flexibility and choice in maintaining euthyroid state has not been tested in children.

OBJECTIVES

To study the efficacy of an alternate day regimen to maintain euthyroidism in children with congenital hypothyroidism.

PATIENTS AND METHODS

Forty patients given alternate day therapy, while 30 children continued on their daily regimen were followed up at monthly intervals for 3 months. Clinical and laboratory assessments were performed at each follow up visit.

RESULTS

The clinical and anthropometric parameters remained similar in both groups of patients during the study indicating a maintained euthyroid state clinically. The thyroid profiles also remained within normal limits suggesting biochemical euthyroidism status with alternate day therapy. However the baseline serum aminotransferase levels showed mild elevation in patients on alternate day regimen and the difference persisted during the follow up visits. Higher HDL and lower TC and LDL levels suggested some beneficial effect of alternate day schedule on lipid profiles.

CONCLUSIONS

In short-term, alternate day schedule can be effectively used to maintain clinical and biochemical euthyroid state in children with congenital hypothyroidism beyond 4 years of age.

Discovery of novel antitubercular 3a,4-dihydro-3H-indeno[1,2-c]pyrazole-2-carboxamide/carbothioamide analogues

In the present investigation, a series of 3a,4-dihydro-3H-indeno[1,2-c]pyrazole-2-carboxamide/carbothioamide analogues were synthesized and were evaluated for antitubercular activity by two fold serial dilution technique. All the newly synthesized compounds showed low to high inhibitory activities against Mycobacterium tuberculosis H(37)Rv and INH resistant M. tuberculosis. The compound 3-(4-fluorophenyl)-6,7-dimethoxy-3a,4-dihydro-3H-indeno[1,2-c]pyrazole-2-carbothioamide (4o) was found to be the most promising compound active against M. tuberculosis H(37)Rv and isoniazid resistant M. tuberculosis with minimum inhibitory concentration 3.12 μM and 6.25 μM, respectively.

Microbiological confirmation of tuberculosis cases at diagnosis and at the end of treatment in Italy

Microbiological findings at diagnosis and at the end of treatment are relevant for evaluating tuberculosis (TB) treatment programmes. The objectives of this study were to describe the microbiological findings at diagnosis and at the end of treatment in pulmonary and extrapulmonary TB patients treated under programme conditions in Italy. The study was a prospective monitoring activity based on the collection of standard recording and reporting forms from a representative sample of Italian TB Units. The forms with individual data were reviewed and analysed on a quarterly basis, 9 months after enrolment. The complete bacteriological profile of patients was analysed at diagnosis and at the completion of treatment. Individual data on 992 patients were analysed. At diagnosis 320 (32.2%) of cases were pulmonary sputum smear positive, 361 (36.4%) pulmonary smear negative or not done and 311 (33.4%) extrapulmonary; 424 (42.7%) of all TB cases were culture confirmed at diagnosis (368, 50.2%, of pulmonary cases); 575 (84.4%) of pulmonary cases had a culture done at diagnosis and 156 (22.9%) at the end of treatment (p < 0.001); 572 (84%) had a sputum smear done at diagnosis and 164 (24.1%) at the end of treatment (p < 0.001). Although the rate of bacteriologically confirmed cases is similar to that of other European countries, the bacteriological confirmation at diagnosis and, particularly, at the end of treatment, is sub-optimal. The importance of further disseminating national guidelines among physicians managing TB is emphasized, in order to achieve a higher proportion of TB cases bacteriologically confirmed at diagnosis and monitored at the end of treatment.

The Italian AIPO study on tuberculosis treatment results, report 1997. National AIPO "Tuberculosis" Study Group

In Italy no national data have been available on tuberculosis (TB) treatment results. In 1995 the AIPO (Italian Association of Hospital Pneumologists) TB Study Group, in collaboration with the Istituto Superiore di Sanità (technical branch of the Ministry of Health) started a prospective monitoring activity based on the recommendations of the World Health Organization and the International Union Against Tuberculosis and Lung Disease. The aim of this study was to analyse the case findings and treatment results during 1997. Data were collected from a representative network of TB units nation-wide, managing a significant proportion of all TB cases notified in Italy each year. A total of 715 TB cases were reported (56% males; 24% immigrants), of which 635 (89%) were new cases. Of these cases 493 (69%) were pulmonary, 187 (26%) extra-pulmonary cases and 35 (5%) both pulmonary and extrapulmonary. The main risk factors for TB were history of recent contact and diabetes among native Italians, human immunodeficiency virus-seropositive status and a history of recent contact among immigrants. The majority of immigrants came from Africa and Central and South America, and stayed in Italy for more than 24 months before the diagnosis of TB was made. Thirty-six per cent of patients had a positive direct sputum smear examination for alcohol acid-fast bacilli and 27% were resistant to any drug (monoresistance to isoniazid: 2.4%; multi-drug resistance: 7.5%). In 97% of cases the duration of treatment was < 12 months. The overall success rate (cured plus treatment completed) was 78.1%. A significantly higher percentage of deaths, which was age related, was found in native Italians, while immigrants had a higher default rate. In conclusion, case finding and treatment results in Italy in 1997 are similar to those described in 1995 and 1996.
