Background: Neurofollicular hamartoma (NFH) is characterized histopathologically by fascicles of spindle cells that laterally delimited by hyperplastic folliculosebaceous units. It usually appears on face, near the nose or nasolabial fold. It does not manifest true neural differentiation and recently the term spindle cell predominant trichodiscoma (SCPT) has been used instead. Case Presentation: We present a case of a 40-year-old male with co-incidence of NFH and basal cell carcinoma (BCC) that the mesenchymal components of NFH were similar to SCPT but these components highly expressed S-100 protein. We also discuss about the histological aspect of the neoplasia in this report and consider the findings of other reports in association with classification of NFH by means of cellular markers and morphological resemblance to other skin hamartomas. Conclusion: Neurofollicular hamartoma is a rare benign tumor that thought to represent the cellular end of a morphological spectrum with trichodiscoma. The morphological features and expression of S100 protein in neural element helped us to achieve the diagnosis of neurofollicular hamartoma. However, variable reports of S-100 protein expression in NFH are available and further studies are needed to determine the classification of this tumor.

Background: Furosemide is a drug widely used for several medical conditions and could be used without medical prescription. Furosemide-related nephrocalcinosis can occur regardless of age, although the risk is higher in premature infants. The defining characteristic of nephrocalcinosis is generalized calcium deposition in the kidney. The most useful imaging studies for evaluation are ultrasonography and computed tomography (more effective in detecting calcification). Case Presentation: A 32-year-old woman with a history of depressive syndrome was admitted for evaluation of fortuitously discovered nephrocalcinosis and hypokalemia. The studies performed revealed the presence of a metabolic alkalosis with discrete hyperreninism/hyperaldosteronism but normal ratio, normotension and urinary study showed elevated sodium, chloride, potassium and calcium fluctuating in different determinations. Surreptitious diuretic intake was suspected and urine analysis revealed doses equivalent to 80-120 mg. The patient was advised to discontinue all diuretic treatment; she was adequately supplemented with potassium and she was followed-up in outpatient clinics. During the follow-up, clinical and analytical improvement was noted, which led to the discontinuation of supplementation. Conclusion: Surreptitious diuretic intake is a clinical condition to rule out in patients with chronic hypokalemia, metabolic alkalosis with elevated urinary sodium and chloride. The relation between surreptitious diuretic intake and nephrocalcinosis has not been fully elucidated in adults.

A 77-year-old man was admitted to the internal medicine department for a 5-day history of progressive preauricular swelling. Two lines of antibiotic treatment failed to achieve any improvement. Fine needle aspiration cytology was conducted and smear staining with the Ziehl-Neelsen stain as well as a PCR test were positive for Mycobacterium tuberculosis. These results were confirmed with culture of the sample. A diagnosis of tuberculosis parotitis was made and anti-tuberculous drugs were initiated.

Internal Medicine - Abstract
A 28-year-old female patient was hospitalized for mild-moderate hypokalaemia which was persistent despite discontinuation of beta-2 agonist bronchodilator treatment. Her past medical history was relevant for two episodes of severe hypokalaemia after active inhaled beta-2 agonist treatment for asthma crisis. Investigations revealed increased potassium in spot urine with a transtubular potassium gradient4. A 24-hour urine analysis showed hypophosphaturia, hypocalciuria, hypomagnesuria and normal urine prostaglandins in favour of Gitelman syndrome. Oral potassium supplementation was started and genetic studies were recommended.An exhaustive aetiological work-up should be performed in young patients with persistent hypokalaemia after withdrawal of bronchodilators.Gitelman syndrome should be suspected in any patient with unexplained hypokalaemia, metabolic alkalosis, and a normal or low blood pressure.

We report the case of a 23-year-old woman evaluated for asthenia and lymphocytopenia. Clinical examination was unremarkable but laboratory tests showed the presence of CD4 lymphocytopenia. Secondary causes of CD4 lymphocytopenia were ruled out and a previous diagnosis of idiopathic CD4+ T-cell lymphocytopenia was retained. CD4 lymphocytopenia has persisted for 11 years now but the patient has been clinically asymptomatic. LEARNING POINTS CD4+ T-cell lymphocytopenia needs to be meticulously evaluated and secondary causes ruled out. The patient has been clinically asymptomatic for 11 years. Measurement of CD4 subsets twice yearly seems to be appropriate.

Myxedema coma is a rare complication of hypothyroidism. Clinical examination may reveal hypotension, bradycardia, and hypothermia. Laboratory tests may show hyponatremia, lipid disorders, and elevations of creatine kinase, liver, and cardiac enzymes. We describe four cases diagnosed in our hospital during the period 1999-2017. The patients were related to amiodarone treatment, noncompliance with hormone replacement therapy, or a new diagnosis of hypothyroidism. Intravenous hormone replacement therapy was effective in three of the cases and one died. The outcome of this disease may be fatal as seen in one of our cases.

Agranulocytosis is a rare, but serious and life-threatening hematologic disorder in elderly patients. Idiosyncratic drug-induced agranulocytosis (IDIA) has been classically defined by a neutrophil count below 0.5 × 109/L. The annual incidence of IDIA in Europe is about 1.6–9.2 cases per million inhabitants. Increasing age and female sex have been considered as risk factors for the development of this condition. Besides, it is well known that older people take on average more drugs than younger people. This condition is most often associated with the intake of antibacterial agents, antiplatelets, antithyroids, antipsychotics, antiepileptics and nonsteroidal anti-inflammatory drugs (NSAIDs). Initially, agranulocytosis may present without symptoms, but may quickly progress to a severe infection and sepsis. The causative drug should be immediately stopped. In febrile patients, blood cultures and where indicated, site-specific cultures should be obtained and early treatment with empirical broad-spectrum antibiotics started. Even with adequate treatment, the mortality rate is higher in elderly patients reaching up to 20%. Hematopoietic growth factors have proven to be useful as they shorten the duration of neutropenia. However, data on neutropenia and agranulocytosis in the elderly meeting the criteria of evidence-based medicine are still poor in the literature. This review analyzes the results of our experience as well as other published studies of the universal literature.
