RESUMO
Status gelasticus is a rare form of status epilepticus characterized by prolonged and/or clustered gelastic seizures. The review encompasses an analysis of cases reported in the literature, focusing on causes, clinical-electroencephalographic features, and therapeutic interventions. The study reveals the challenges in defining and understanding status gelasticus due to its diverse etiologies and limited reported cases. The association with hypothalamic hamartomas and other brain abnormalities underscores the importance of thorough evaluations. The review also discusses new treatments, including medications and less invasive surgeries. While progress has been made, the study points out challenges in diagnosing and managing this complex condition, highlighting the importance of ongoing research.

The post-surgical outcome for Hypothalamic Hamartoma (HH) related epilepsy in terms of seizure freedom (SF) has been extensively studied, while cognitive and psychiatric outcome has been less frequently reported and defined. This is a systematic review of English language papers, analyzing the post-surgical outcome in series of patients with HH-related epilepsy (≥5 patients, at least 6 months follow-up), published within January 2002-December 2022. SF was measured using Engel scale/equivalent scales. We looked at the outcome related to different surgical techniques, and HH types according to Delalande classification. We evaluated the neuropsychological and neuropsychiatric status after surgery, and the occurrence of post-surgical complications. Forty-six articles reporting 1318 patients were included, of which ten pediatric series. SF was reported in 686/1222 patients (56,1%). Delalande classification was reported in 663 patients from 24 studies, of which 70 were type I HH (10%), 320 were type II HH (48%), 189 were type III HH (29%) and 84 were type IV HH (13%). The outcome in term of SF was reported in 243 out of 663 patients. SF was reported in 12 of 24 type I HH (50%), 80 of 132 type II HH (60,6%), 32 of 59 type III HH (54,2%) and 12 of 28 type IV HH (42,9%). SF was reached in 129/262 (49,2%) after microsurgery, 102/199 (51,3%) after endoscopic surgery, 46/114 (40,6%) after gamma knife surgery, 245/353 (69,4%) after radiofrequency thermocoagulation, and 107/152 (70,4%) after MRI-guided laser interstitial thermal therapy. Hyperphagia/weight gain were the most reported surgical complications. Others were electrolyte alterations, diabetes insipidus, hypotiroidism, transient hyperthermia/poikilothermia. The highest percentage of memory deficits was reported after microsurgery, while hemiparesis and cranial nerves palsy were reported after microsurgery or endoscopic surgery. Thirty studies reported developmental delay/intellectual disability in 424/819 (51,7%) patients. 248/346 patients obtained a global improvement (72%), 70/346 were stable (20%), 28/346 got worse (8%). 22 studies reported psychiatric disorders in 257/465 patients (55,3%). 78/98 patients improved (80%), 13/98 remained stable (13%), 7/98 got worse (7%). Most of the patients had non-structured cognitive/psychiatric assessments. Based on the available data, the surgical management in patients with HH related epilepsy should be individualized, aiming to reach not only the best epilepsy result, but also the optimal cognitive and psychiatric outcome.

Hypothalamic hamartomas (HHs) are rare congenital lesions formed by heterotopic neuronal and glial cells attached to the mammillary bodies, tuber cinereum, and hypothalamus.They often present with an intractable epilepsy typically characterized by gelastic seizures but commonly associated with other types of refractory seizures. The clinical course is progressive in most of the cases, starting with gelastic seizures in infancy and deteriorating into complex seizure disorders that result in catastrophic epilepsy associated with cognitive decline and behavioral disturbances.Hamartomas are known to be intrinsically epileptogenic and the site of origin for the gelastic seizures. As antiepileptic drugs are typically ineffective in controlling HH-related epilepsy, different surgical options have been proposed as a treatment to achieve seizure control. Resection or complete disconnection of the hamartoma from the mammillothalamic tract has proved to achieve a long-lasting control of the epileptic syndrome.Usually, symptoms and their severity are typically related to the size, localization, and type of attachment. Precocious puberty appears mostly in the pedunculated type, while epileptic syndrome and behavioral decline are frequently related to the sessile type. For this reason, different classifications of HHs have been developed based on their size, extension, and type of attachment to the hypothalamus.The bigger and more complex hypothalamic hamartomas typically present with severe refractory epilepsy, behavioral disturbances, and progressive cognitive decline posing a formidable challenge for the control of these symptoms.We present here our experience with the multimodal treatment for complex hypothalamic hamartomas. After an in-depth review of the literature, we systematize our approach for the different types of hypothalamic hamartomas.

Neurofibroma is an autosomal benign disorder. It can be localized, diffuse or invasive like plexiform neurofibroma that involves the nerves, muscle, tissues, skeleton. It represents itself as a destructive variant of neurofibroma, mostly present as orbital or periorbital neurofibroma or may be associated with autosomal dominant disease. Clinical diagnosis of neurofibromatosis (NF) according to National Institutes of Health (NIH) criteria should have more than two of the seven features including lisch nodules, cafe'- au-lait spots, plexiform neurofibroma, optic glioma, freckling, first degree relative with NF or dysplasia of cortical bones. However, proper early diagnosis is still crucial due to its various presentation such as cheek mass, painless swelling on skin, chalazion, intratracheal tumor, genital swelling or ptosis. It is reported that neurofibroma often represents as ocular or facial swelling. Here we are presenting features of neurofibroma of eight cases of patients from Civil Hospital, Karachi. These cases had main complain of overhanging skin mass mainly on orbital or periorbital region that damage the area and with poor daily activities. Multiple nodules on face and body along with them Cafe'-au-lait spots and lisch nodules were main signs. While, other signs i.e. ptosis, pterygium, telecanthus and muddy discoloration of conjunctiva need further evaluation for correlation with neurofibromatosis. Debulking surgery was planned for most of the cases but the huge disfigurement caused by overhanging skin mass and nodules made it a challenge for plastic surgeons to provide good outcomes with minimum damage. Keywords: neurofibroma; lisch nodules; ptosis; Cafe'-au-lait spot; periorbital; overhanging skin.

BACKGROUND: Hamartoma is a common benign tumor that usually occurs in the kidney, liver, lung, and pancreas. Large renal hamartomas may spontaneously rupture and hemorrhage, which is potentially life-threatening. CASE PRESENTATION: This report describes a 46-year-old Han Chinese female patient with multiple renal and hepatic hamartomas with rupture and hemorrhage of giant hamartoma in the left kidney. She underwent arterial embolization three times successively, and her condition was stable during the 2-year follow-up. This report includes a review of the relevant literature CONCLUSIONS: the findings in this report and previous literature suggest that arterial embolization can not only rapidly treat hamartoma hemorrhage in the acute phase but can also effectively control multiple lesions in the long term after repeated multisite arterial embolization.

We report the case of ileo-ileal intussusception secondary to a Peutz-Jeghers syndrome (PJS) hamartomatous polyp in a male infant. The patient presented with non-bilious vomiting and a single episode of passing blood in his stool. An upper gastrointestinal contrast study showed proximal bowel obstruction. At laparotomy, ileo-ileal intussusception was identified with a papillary mass acting as a lead point. The mass was resected, and a primary anastomosis was performed. The patient recovered well and was discharged on postoperative day 5. Histological assessment diagnosed a PJS hamartoma. The patient was well at 1 month follow-up. This case report describes a rare cause of intussusception in an infant that should be considered in the differential diagnosis. The diagnosis of PJS in infancy is uncommon and requires long-term follow-up.

Achieving favorable seizure outcomes is challenging in patients with seizures resulting from hypothalamic hamartoma. Although minimally invasive and non-invasive surgical procedures are used to treat this population, these procedures have limitations. Therefore, we analyzed the outcomes of patients with hypothalamic hamartoma following direct resection. We included 159 patients with hypothalamic hamartoma who underwent direct resection using the transcallosal interforniceal approach between 2011 and 2018. The relationships between clinical parameters and seizure outcomes were analyzed. In total, 55.3% achieved gross total resection and 25.2% underwent near-total resection. Of all patients, 79.2% were overall seizure-free at one year, but this number dropped to 77.0% at more than five years. Moreover, 88.4% (129/146) reached gelastic seizure (GS)-free status at one year and this number increased to 89.0% (97/109) at more than five years. Seventy-one patients took antiseizure medication (ASM) long-term, 68 took it for one year, and 11 took it for one-half year. The duration of ASM consumption (p < 0.001) and extent of hypothalamic hamartoma resection (p = 0.016) were significant independent predictors of long-term overall seizure-free survival, while the duration of ASM consumption (p = 0.011) and extent of hypothalamic hamartoma resection (p = 0.026) were significant independent predictors of long-term GS-free survival. Most patients' behavior, school performance, and intelligence were not affected after surgery. Direct resection is effective and safe strategy for patients with hypothalamic hamartomas. Hypothalamic hamartomas should be removed as completely as possible, and patients should take ASM long-term following surgery to reach long-term overall seizure-free or GS-free status.

BACKGROUND AND OBJECTIVES: Gelastic seizures due to hypothalamic hamartomas (HH) are challenging to treat, in part due to an incomplete understanding of seizure propagation pathways. Although magnetic resonance imaging-guided laser interstitial thermal therapy (MRgLITT) is a promising intervention to disconnect HH from ictal propagation networks, the optimal site of ablation to achieve seizure freedom is not known. In this study, we investigated intraoperative post-ablation changes in resting-state functional connectivity to identify large-scale networks associated with successful disconnection of HH. METHODS: Children who underwent MRgLITT for HH at two institutions were consecutively recruited and followed for a minimum of one year. Seizure freedom was defined as Engel score of 1A at the last available follow-up. Immediate pre- and post- ablation resting-state functional MRI scans were acquired while maintaining a constant depth of general anesthetic. Multivariable generalized linear models were used to identify intraoperative changes in large-scale connectivity associated with seizure outcomes. RESULTS: Twelve patients underwent MRgLITT for HH, five of whom were seizure-free at their last follow-up. Intraprocedural changes in thalamocortical circuitry involving the anterior cingulate cortex were associated with seizure-freedom. Children who were seizure-free demonstrated an increase and decrease in connectivity to the pregenual and dorsal anterior cingulate cortices, respectively. In addition, children who became seizure-free demonstrated increased thalamic connectivity to the periaqueductal gray immediately following MRgLITT. DISCUSSION: Successful disconnection of HH is associated with intraoperative, large-scale changes in thalamocortical connectivity. These changes provide novel insights into the large-scale basis of gelastic seizures and may represent intraoperative biomarkers of treatment success.

BACKGROUND: To describe a rare seizure semiology originating from a hypothalamic hamartoma in a child, along with unusual ictal onset and connectivity pattern, and provide a review of the pathophysiology of epilepsy associated with hypothalamic hamartoma and management. METHODS: A detailed retrospective chart review and literature search were performed using Pubmed and Embase. RESULTS: We present a case of a three-year-old male who presented with dyscognitive seizures with onset at age 22 months. Stereoelectroencephalography exploration confirmed the onset in hypothalamic hamartoma with rapid propagation to the temporal-parietal-occipital association cortex and precuneus. The patient's epilepsy was cured with laser ablation of the hamartoma. CONCLUSION: Published literature mostly describes a more anterior frontal or temporal epileptic network with primarily gelastic seizures being the hallmark type of seizures associated with hypothalamic hamartoma. We highlight a rare posterior cortex network with an atypical presentation of focal nonmotor seizures with impaired awareness in the setting of a hypothalamic hamartoma. Stereotactic laser ablation of the hamartoma rendered seizure freedom. Early diagnosis and appropriate treatment can lead to seizure freedom.

BACKGROUND: Von Meyenburg complexes are benign hamartomatous lesions, they are part of the spectrum of ductal plate malformations. They are rare, reported in 0.35-5.6% of the general population, predominantly in adults, with no clear predilection for sex. OBJECTIVE: To present the clinical characteristics of Von Meyenburg complexes in our region. METHOD: We searched all cases with diagnosis of Von Meyenburg complexes in a period from 2012 to 2022, in our institutions. RESULTS: We identified eight cases, with an average age of 59.25 years, with a predominance of females and with one case associated with gastric carcinoma. CONCLUSIONS: It is important to adequately recognize this entity, since due to its multifocal nature it can easily simulate metastasis, additionally, and its presence does not rule out other synchronous neoplasms.

Angiomyolipoma is a common benign solid tumour that accounts for up to 3% of all renal tumours; most of the cases are sporadic. However, it can be part of other diseases. Angiomyolipomas are usually found incidentally through unrelated clinically indicated images but also, they can be diagnosed after complications have occurred. We report the case of retroperitoneal haemorrhage following the rupture of renal angiomyolipoma post-fibrinolysis, we are highlighting such a rare condition, the management options and the follow-up plan. The management of angiomyolipomas ranges from conservative treatment to surgical intervention depending on the patient's condition and the tumour's radiological features. Following-up on patients with angiomyolipomas depends on the symptoms and the tumour size. Till date, there is no reported cases of renal angiomyolipoma rupture post-fibrinolysis therapy as a treatment for myocardial infarction in non-percutaneous intervention capable facility.

Abstract Basaloid follicular hamartoma is a benign, superficial malformation of hair follicles that can be mistaken both clinical and histopathologically for basal cell carcinoma. Basaloid follicular hamartoma has been linked to a mutation in the PTCH-1 gene, which is part of the same pathway involved in Gorlin-Goltz syndrome. Here we present a 9-year-old patient with an asymptomatic congenital lesion on the forehead, which increased in size over the years. Histopathology showed a basaloid follicular hamartoma associated with follicular mucinosis and inflammation. Gorlin-Goltz syndrome was ruled out by clinical examination.

La esclerosis tuberosa es una enfermedad autosómica dominante con gran variabilidad de expresión clínica. Se caracteriza por la presencia de tumores benignos en distintos órganos debidos a un desorden en la proliferación y diferenciación celular. Afecta, especialmente, la piel, el sistema nervioso central, el corazón y el riñón. El compromiso intestinal es infrecuente; afecta a adultos y compromete el colon sigmoide y el recto. En niños, hay solo dos casos descritos en la literatura; nuestra paciente sería el tercero. Presentamos a una paciente con esclerosis tuberosa, que comenzó, desde el mes de vida, con cuadros reiterados de suboclusión intestinal. La videocolonoscopía mostró una formación mamelonada que protruía hacia la luz del colon ascendente. Se realizó una hemicolectomía derecha. El informe anatomopatológico correspondió a un pólipo hamartomatoso. La evolución clínica y nutricional en el posquirúrgico fue muy favorable. Aunque poco frecuente, el pólipo hamartomatoso debe considerarse en el diagnóstico diferencial de oclusión intestinal en pediatría.
Tuberous sclerosis is an autosomal dominant disorder with a wide clinical spectrum of disease. It is characterized by development of benign tumors in multiple organs due to a disturbance in cellular growth and differentiation. It usually affects skin, brain, heart and kidney. Gastrointestinal involvement is rare and mainly restricted to adults and sigmoid colon and rectum. In children there are only two cases; our patient would be the third. We present a patient with tuberous sclerosis who began at the first month of life with repeated intestinal subocclusion. The videocolonoscopy showed a mass protruding into the lumen of the ascending colon. Right hemicolectomy was performed. The anatomopathological report corresponded to a hamartomatous polyp. The clinical and nutritional evolution in the postoperative period was very favorable. Although uncommon, the hamartomatous polyp should be considered in the differential diagnosis of intestinal occlusion in pediatrics.

El nevo de Becker, es un hamartoma cutáneo benigno de etiología desconocida, que se presenta como una mácula hiperpigmentada de bordes geográficos. Por lo general, se ubica en la región torácica superior y su compromiso tiende a ser unilateral. Ocasionalmente el nevo de Becker se asocia a anomalías en el tejido óseo, muscular o cutáneo, siendo la ictiosis una característica muy infrecuente. La presencia de alguna de estas anomalías asociadas a un Nevo de Becker determina el síndrome del Nevo de Becker. Paciente de sexo masculino de 18 años, que consultó por un cuadro iniciado en la infancia, caracterizado por la aparición de manchas cafés, escamosas, pruriginosas que inicialmente se ubicaron en las extremidades inferiores y con el tiempo fueron apareciendo en tronco, región lumbar y glútea. Mediante la correlación clínico-patológica se llegó al diagnóstico de Nevo de Becker, con características ictiosiformes. Se realizaron estudios complementarios con ecocardiograma Doppler y radiografía de tórax, que resultaron normales y una ecotomografía Doppler color de tórax anterior que mostró una leve ginecomastia bilateral con discreto aumento del botón mamario derecho y una leve hipoplasia del pectoral mayor derecho diagnosticándose Síndrome de Nevo de Becker. La mayoría de los reportes de Síndrome de nevo de Becker describen anomalías como escoliosis o hipoplasia unilateral de la mama, con escasos reportes sobre ictiosis. Se reporta este caso por su presentación atípica con múltiples nevos de Becker, compromiso de hemicuerpo inferior y su asociación ictiosiforme poco descrita en la literatura.
Becker's nevus is a benign cutaneous hamartoma of unknown etiology; it appears as a hyperpigmented macula with geographical borders. Usually it is located in the upper thoracic region, unilaterally. Occasionally Becker nevus is associated with abnormalities in the bony, muscle or skin tissue, being ichthyosis an unusual feature. The presence of some of these anomalies associated with Becker´s nevus determine the Becker´s nevus syndrome. Male patient of 18 years old who had a clinical history that begun in childhood, characterized by the appearance of brown, scaly, itchy patch that initially were located in the lower extremities and eventually were appearing in the trunk, lumbar and gluteal area. The clinical-pathological correlation led us to the diagnosis of Becker´s nevus with ichthyosiform features. Additional studies were performed such as Doppler echocardiography and chest radiograph, both normal. Color Doppler ultrasonography of anterior chest showed a slight bilateral gynecomastia with discrete increase of the right breast and a slight hypoplasia of the right major pectoral, determining a Becker´s nevus syndrome. Most reports of Becker´s nevus syndrome described abnormalities such as scoliosis or unilateral breast hypoplasia, few cases have been reported with ichthyosis. This case is reported for its atypical presentation with multiple Becker´s nevus, compromise of the lower body and its ichthyosiform association, rarely described in the literature.

Los hamartomas hipotalámicos son malformaciones no neoplásicas de sustancia gris compuestas por neuronas hiperplásicas. Suelen ser lesiones pequenas localizadas en la base del cerebro, en el piso del tercer ventrículo y, generalmente, asintomáticas. Sin embargo, pueden ocurrir con alteraciones conductuales-cognitivas, crisis epilépticas y/o signos de pubertad precoz central en función de la localización en la que se encuentren. Se presentan dos pacientes de 2 años 8 meses y 7 años, con presencia de hamartomas hipotalámicos diagnosticados tras el estudio de pubertad precoz central. La paciente de menor edad presenta, además, crisis gelásticas, típicamente asociadas a hamartomas hipotalámicos. Tras los hallazgos clínicos y radiológicos, se trataron con análogos de gonadotropinas, y se observó una regresión de los signos puberales y una no progresión del tamano de los hamartomas.
Hypothalamic hamartomas are benign tumors of gray substance composed by hyperplasic neurons. They are usually asymptomatic small masses with extensions into the third ventricular cavity. In some instances they can cause cognitive behavioral alterations, seizures and/or central precocious puberty depending on the location. Here we present two cases of central precocious puberty due to hypothalamic hamartomas at 2(8/12) and 7 years of age. The younger patient also presents gelastic seizures, typically associated with hypothalamic hamartomas. After the clinical and radiological findings, they started treatment with GnRH analogues and a regression of the puberty signs without progression in the hamartomas size was observed.

A full-term male neonate with anorectal anomaly and external perineal anomalies was referred to our service. Physical examination showed an epithelized perineal mass with cutaneous orifices, which had urine fistulization, hipotrofic perineal musculature, bilateral congenital clubfoot, hipospadic urethra, criptorquidy bilateral with nonpalpable testis and imperforate anus. A colostomy was constructed immediately after birth. The child underwent excision of perineal mass, bilateral orchidopexy, Duplay neourethroplasty and coloanal anastomosis at 3 months of age. The histopathological examination of the perineal mass revealed a hamartoma.

O início da puberdade caracteriza-se pelo aumento de amplitude e frequência dos pulsos do hormônio secretor de gonadotrofinas (GnRH) após um período de relativa supressão hormonal durante a infância. A reemergência da secreção pulsátil do GnRH resulta em aumento na secreção de gonadotrofinas, hormônio luteinizante (LH) e folículo estimulante (FSH), pela hipófise anterior e consequente ativação gonadal. A ativação prematura do eixo hipotálamo-hipófise-gonadal resulta em puberdade precoce dependente de gonadotrofinas, também conhecida como puberdade precoce central (PPC), e se caracteriza pelo desenvolvimento dos caracteres sexuais secundários antes dos 8 anos nas meninas e 9 anos nos meninos. O início do desenvolvimento puberal provém da interação complexa de fatores genéticos, nutricionais, ambientais e socioeconômicos. O diagnóstico clínico da PPC baseia-se em reconhecimento de desenvolvimento puberal progressivo, concentrações púberes de LH em condição basal e/ou após estímulo com GnRH e avanço de idade óssea. A ressonância magnética de encéfalo é útil no estabelecimento de diagnóstico diferencial entre as formas orgânica ou idiopática. Os análogos de GnRH de ação prolongada representam o tratamento de escolha da PPC. O componente genético da PPC foi recentemente fortalecido pela evidência de mutações no gene MKRN3, localizado no braço longo do cromossomo 15, em crianças com PPC familial. Nessa revisão, dados clínicos e terapêuticos da PPC serão amplamente discutidos, visando à atualização e à conduta criteriosa dessa condição clínica de grande relevância na endocrinologia pediátrica.
The onset of puberty is first detected as an increase in the amplitude and frequency of pulses of gonadotropin-releasing hormone (GnRH) after a quiescent period during childhood. The reemergence of pulsatile GnRH secretion leads to increases in the secretion of the gonadotropins, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) by the pituitary gland, and the consequent activation of gonadal function. Early activation of the hypothalamic–pituitary–gonadal axis results in gonadotropin-dependent precocious puberty, also known as central precocious puberty (CPP), which is clinically defined by the development of secondary sexual characteristics before the age of 8 years in girls and 9 years in boys. Pubertal timing is influenced by complex interactions among genetic, nutritional, environmental, and socioeconomic factors. CPP is diagnosed on the basis of clinical signs of progressive pubertal development before the age of 8 years in girls and 9 years in boys, pubertal basal and/or GnRH-stimulated LH levels, and advanced bone age. Magnetic resonance imaging of the central nervous system is essential for establishing the CPP form as organic or idiopathic. Depot GnRH-analogues represent the first-line of therapy in CPP. Very recently, the genetic component of CPP was demonstrated by the evidence that the deficiency of the MKRN3 gene, located on long arm of chromosome 15, causes familial CPP in humans. In this current review, clinical and therapeutic aspects of the CPP will be discussed, contributing to adequate diagnosis and criterious approach of this relevant condition of pediatric endocrinology.
