Comparison of frequency of insulin resistance in patients with chronic obstructive pulmonary disease with normal controls
Objective: To compare mean homeostatic model assessment of insulin resistance (HOMA-IR) in patients with and without chronicobstructive pulmonary disease (COPD).
Methods: A Case control analytic study was conducted in medical outpatient department of Medial Unit-II of Dow University of Health Sciences from April 2013 to September 2013. All patients with the diagnosis of COPD were included as cases. Controls were age match healthy individuals with minor illnesses. Age, weight, height and forced expiratory volume in one second to forced vital capacity (FEV1/FVC) ratio were documented. Fasting blood glucose and fasting insulin levels were done. Body mass index (BMI) and IR was calculated using the formulas. HOMA-IR was compared between cases and controls.
Results: Forty COPD patients were compared with thirty five age match controls. HOMA-IR was found to be higher in cases as compared to controls (2.85 v/s 2.00) with a p value \u3c0.000.
Conclusion: COPD is one of the chronic debilitating diseases in our region with various extra-pulmonary complications. We found IR to be present higher in COPD patients compared with healthy controls. Evaluating the pulmonary function as well as systemic metabolic parameters, may contribute to minimizing mortality and morbidity
Idiopathic hypogonadotropic hypogonadism reversal after testosterone replacement in a 34-year-old male
A 34-year-old male presented to the endocrinology clinic with the complaint of the absence of facial, axillary and pubic hairs. Further history revealed absent ejaculations and decreased early morning erections. The patient had no history of headaches, visual problems or anosmia. On physical examination, there were sparse facial, axillary and pubic hairs, bilateral gynaecomastia, stretch penile length of 5 cm and bilateral testicular volume of 10 mL. Laboratory investigations showed low luteinising hormone, follicular stimulating hormone and testosterone with normal prolactin and thyroid profile. MRI of the pituitary gland showed no evidence of pituitary microadenoma or macroadenoma. The patient was started on testosterone injections. After 9 months of testosterone replacement, the patient\u27s testicular size increased to 20 mL bilaterally and his penile length increased to the mean adult size for his age with normal testosterone and luteinising hormone. He was, thus, advised to discontinue testosterone therapy
Metastatic choriocarcinoma in a young woman presenting as thyroid storm: A case report
Background: Thyroid storm is an endocrine emergency and life-threatening condition discovered in 1926. There is no specific laboratory parameter that can differentiate or distinguish between thyroid storm and primary hyperthyroidism. Diagnosis is made on a clinical scoring system, including the Burch-Wartofsky point scale and Japanese Thyroid Association scoring system. The management is early diagnosis, immediate initiation of anti-thyroid medications, intensive care monitoring, and prevention of multiorgan failure.Case presentation: A 30-year-old Pakistani female presented with complaint of headache, vomiting, and generalized weakness for 3 weeks. She had an episode of seizure-like activity at home, and so was rushed to the emergency department. A detailed thyroid examination revealed a soft, nontender gland with no enlargement or bruit and no exophthalmos. Her thyroid-stimulating hormone was extremely low, with high free triiodothyronine and thyroxine. Thyroglobulin was 425 ng/ml (normal reference range ≤ 55 ng/ml), and thyroid-stimulating hormone receptor antibody was 0.87 IU/L (normal reference range 0-1.75 IU/L). She had high levels of beta-human chorionic gonadotropin hormone on initial presentation. Transvaginal ultrasound showed no intrauterine pregnancy, but an echogenic focus was found adherent to the right ovary with no vascularity. With the chief complaint of headache, she underwent magnetic resonance imaging of the brain that showed multiple scattered hemorrhagic lesions in supratentorial and infratentorial brain parenchyma that were highly suspicious for metastases. Computed tomography scan of the chest, abdomen, and pelvis revealed multiple neoplastic lesions in the lung, liver, spleen, and kidneys. A Tru-Cut liver biopsy showed linear cores of liver tissue with metastatic carcinoma with morphological features consistent with choriocarcinoma. Our patient scored 65 on the Burch-Wartofsky point scale. As per the Japanese Thyroid Association scoring system, our patient met the criteria for a definite thyroid storm. She had initiated propranolol to achieve adequate control of her heart rate and dexamethasone. Carbimazole was started to control her thyroid function. Her thyroid function after 2 weeks of treatment showed significant improvement. Methotrexate and etoposide were given for choriocarcinoma. She made a good recovery and was discharged home. She will undergo rehabilitation along with ongoing chemotherapy (methotrexate and etoposide weekly till beta-human chorionic gonadotropin levels normalize). Unless her source of beta-human chorionic gonadotropin is carefully under control, she will continue to take anti-thyroid medications.Conclusion: Choriocarcinoma is not only associated with hyperthyroidism but can induce thyroid storm. Beta-human chorionic gonadotropin is directly associated with promoting thyroid dysfunction. Patients with gestational trophoblastic disease should be under close surveillance to prevent thyroid storms
Neonatal outcomes and congenital anomalies in pregnancies affected by hypothyroidism
Background: Maternal hypothyroidism has been reported to have concerns over neonatal outcomes, not only in the context of neurocognitive development but also in the short term as birth weight and neonatal jaundice.Patients and methods: We conducted a cross-sectional retrospective study on 638 cases who delivered live births in the Aga Khan University Hospital after ethical approval. Data were collected on hypothyroid pregnant females who were diagnosed before conception or during their antenatal visits during the year 2008-2016. Neonatal outcomes were noted for birth weight, maturity, and neonatal jaundice, neonatal hypothyroidism, neonatal respiratory distress syndrome, sepsis, hypocalcaemia, congenital anomalies, need for intensive care admission, and neonatal death. Subgroup analysis was performed on the timing of diagnosis of maternal hypothyroidism. Data analysis was performed on Statistical Package for the Social Sciences version 20.0.Results: Neonatal jaundice was the most common neonatal outcome (37.6%) in our cohort of 662 live births. Nearly 15% required intensive care unit admission, however, neonatal death was very rare. The most common clinically significant congenital anomalies were cardiovascular defects, whereas Mongolian spots were the commonest congenital condition to report. There is a statistically significant association between low birth weight (OR 1.86, 95% CI 1.0-3.2, p ≤ 0.05) and congenital anomalies (OR 2.39, 95% CI 1.4-4.0, p ≤ 0.05) with women diagnosed with hypothyroidism before pregnancy.Conclusion: We report the neonatal outcomes and spectrum of congenital anomalies of hypothyroid pregnancies diagnosed before and during conception for the first time from the region of Pakistan.Key Message: Overall, none of the neonates of hypothyroid pregnancies developed congenital hypothyroidism.Cardiovascular defects in these neonates imply extensive screening and monitoring during pregnancy.Low birth weight and congenital anomalies are associated with the timings of diagnosis of hypothyroidism in pregnancy
DIABETIC KETOACIDOSIS CHARACTERISTICS AND DIFFERENCES IN TYPE 1 VERSUS TYPE 2 DIABETES PATIENTS
Background: Diabetes is undoubtedly one of the most challenging health problems of the 21st century. It is well known that diabetes once develop can lead to several complications. Diabetic ketoacidosis (DKA) is one of the life-threatening complications of diabetes. This study was designed to determine the frequency of DKA in diabetes patients and find out the clinical and biochemical determinants of DKA.
Methods: This descriptive study was conducted at Aga Khan University Hospital (AKUH) Karachi, Pakistan from January 2010 to February 2016. All known or newly diagnosed diabetic patients of \u3e16 years of age irrespective of gender and type of diabetes were included. Information regarding patient’s demographics, presenting symptoms, precipitating causes of DKA, biochemical profiles and outcome at the time of discharge was collected.
Results: Majority (54.7%) had moderate and 12.4% had severe DKA at presentation. Previous history of DKA was found higher in type 1 diabetes patients (T1DM) (14%) as compare to (4%) type 2 diabetes patients (T2DM) (p\u3c0.05). DKA severity was observed more (12%) in newly diagnosed (T1DM) (p\u3c0.05). Comorbidities were found more (81%) in (T2DM) (p\u3c0.05) Mortality was also observed higher in Type 2 diabetes patients (p\u3c0.05).
Conclusion: Majority of the diabetics had moderate to severe DKA at presentation. Mortality and morbidity related with DKA was found considerably higher among patients with T2DM while infection, myocardial infarction and stroke found as triggering factors in these patients
Localizing an occult insulinoma by selective calcium arterial stimulation test: First ever experience and a new dimension to diagnosis in Pakistan
Insulinomas are rare, usually benign, solitary tumours accounting for 60% of islet cell tumours. These tumours can be difficult to localize preoperatively due to their small size. We present a challenging case of a 40 year old male with frequent hypoglycaemic spells and endogenous hypoglycaemia who presented as a diagnostic dilemma. Patient had an occult insulinoma with inconclusive CT Abdomen, MRI Abdomen and Octreotide scan. The final localization of the tumour was made by selective arterial calcium stimulation testing (SCAT), done for the first time in Pakistan at Aga Khan University Hospital. This was followed by successful distal pancreatectomy as localizd by SACT yielding a well differentiated neuroendocrine tumour. After surgery patient made a robust recovery with no further hypoglycaemic symptoms. Hence successful localization and management of occult insulinomas can be challenging but can be achieved with the advent of newer invasive modalities
Hypopituitarism other than sellar and parasellar tumors or traumatic brain injury assessed in a tertiary hospital
Objective: Data regarding the etiology, clinical and biochemical patterns in hypopituitarism is scant for Pakistan. We describe the characteristics of patients with hypopituitarism other than sellar and parasellar tumors or traumatic brain injury from a tertiary care center in Pakistan.
Methods: We conducted a retrospective descriptive study in the Aga Khan University Hospital, Karachi, Pakistan. We studied all patients presenting with hypopituitarism, between January 2004 and December 2013. Clinical, hormonal and imaging data pertinent to the study was collected according to inclusion criteria.
Results: Forty-two patients presented to the endocrinology clinics at the Aga Khan University Hospital during the study period. Thirty-seven patients (88.1%) were females. Mean age ± standard deviation of the participants was 53.8 ± 14.7 years. Sixteen patients had secondary infertility and all were females; a majority of patients in this group had Sheehan\u27s syndrome (n=8) followed by empty sella syndrome (n=3), partial empty sella syndrome (n=2), idiopathic cause (n=2) and tuberculoma (n=1). Eighteen females (48.6%) reported inability to lactate.
Conclusions: Non-traumatic hypopituitarism was more common in women, with Sheehan syndrome being the most common cause of hypopituitarism in our study (35.7%). Secondary hypothyroidism was the most common hormonal deficiency. The most commonly reported symptom was weakness
Three siblings with familial non-medullary thyroid carcinoma: a case series
Abstract BACKGROUND:
In 2015, thyroid carcinoma affected approximately 63,000 people in the USA, yet it remains one of the most treatable cancers. It is mainly classified into medullary and non-medullary types. Conventionally, medullary carcinoma was associated with heritability but increasing reports have now begun to associate non-medullary thyroid carcinoma with a genetic predisposition as well. It is important to identify a possible familial association in patients diagnosed with non-medullary thyroid carcinoma because these cancers behave more destructively than would otherwise be expected. Therefore, it is important to aggressively manage such patients and screening of close relatives might be justified. Our case series presents a diagnosis of familial, non-syndromic, non-medullarycarcinoma of the thyroid gland in three brothers diagnosed over a span of 6 years. CASE PRESENTATIONS:
We report the history, signs and symptoms, laboratory results, imaging, and histopathology of the thyroid gland of three Pakistani brothers of 58 years, 55 years, and 52 years from Sindh with non-medullary thyroid carcinoma. Only Patients 1 and 3 had active complaints of swelling and pruritus, respectively, whereas Patient 2 was asymptomatic. Patients 2 and 3 had advanced disease at presentation with lymph node metastasis. All patients underwent a total thyroidectomy with Patients 2 and 3 requiring a neck dissection as well. No previous exposure to radiation was present in any of the patients. Their mother had died from adrenal carcinoma but also had a swelling in the front of her neck which was never investigated. All patients remained stable at follow-up. CONCLUSIONS:
Non-medullary thyroid carcinoma is classically considered a sporadic condition. Our case report emphasizes a high index of suspicion, a detailed family history, and screening of first degree relatives when evaluating patients with non-medullarythyroid carcinoma to rule out familial cases which might behave more aggressively
Incidental metastatic mediastinal atypical carcinoid in a patient with parathyroid adenoma: a case report.
Background: Atypical carcinoid arising from the mediastinal tissue is a rare neuroendocrine tumor and an association with parathyroid adenoma is very unusual. We report an unusual case of atypical carcinoid of mediastinum with metastasis in a patient presenting with parathyroid adenoma, which is the first case to be reported from Pakistan.
Case presentation: A 51-year-old Pakistani man was seen in postoperative intensive care after right parathyroidectomy and mediastinal mass resection for the management of postoperative hypocalcaemia. He had a background history of dyspnea. Examination was unremarkable. Preoperative laboratory evaluation revealed a calcium level of 12.7 mg/dl, phosphate of 1.9 mg/dl, serum albumin of 4.8 g/dl, alkaline phosphate of 94 U/L, and serum intact parathyroid hormone level 413.8 pg/ml. A technetium-99m sestamibi parathyroid scan showed right parathyroid increased tracer uptake. Further workup revealed a large mediastinal mass which was diagnosed as atypical carcinoid after Tru-Cut biopsy. He underwent right-sided parathyroidectomy and resection of the mediastinal mass. The histopathology confirmed it to be a parathyroid adenoma and atypical carcinoid tumor of his mediastinum with metastasis in his lymph node and parathyroid gland. Somatostatin receptor scintigraphy revealed a well-defined focus in his left hypochondriac region consistent with a somatostatin receptor scintigraphy-avid tumor. He was started on everolimus and planned for octreotide therapy.
Conclusions: We describe an incidental finding of atypical carcinoid of the mediastinum in a patient diagnosed as having parathyroid adenoma. Clinical manifestations of neuroendocrine syndromes are challenging. Some tumors cluster in a non-classic description with other common neoplasms. They rarely present in isolation, remain clinically silent, and need aggressive workup with the aid of imaging and histopathology
Maternal characteristics and outcomes affected by hypothyroidism during pregnancy (Maternal hypothyroidism on pregnancy outcomes, MHPO-1)
Background: Hypothyroidism in pregnancy is an arena of ongoing research, with international conflicts regarding screening, management, and outcomes. Various studies have described the outcomes depending on geographical and international diagnostic criteria. No study has been conducted in this regard from the region of Pakistan. Therefore, we aim to report the clinical features and maternal outcomes of hypothyroid pregnancies and compare the maternal outcomes between uncontrolled and controlled TSH levels in the preconception as well as the gestational period.Methods: We conducted a cross-sectional retrospective study on 718 cases in the Aga Khan University Hospital after ethical approval. We collected information on pregnant females who have diagnosed hypothyroidism before conception or during their antenatal period. We noted the maternal characteristics and maternal comorbidities. Laboratory data were recorded for thyroid stimulating hormone levels before conception and during gestation. We recorded maternal outcomes as pregnancy loss (including miscarriage, stillbirth/intrauterine death, medical termination of pregnancy and ectopic pregnancy), gestational hypertension, pre-eclampsia, postpartum hemorrhage, placental abruption, and modalities of delivery. Data analysis was performed on Statistical Package for the Social Sciences version 20.0.Results: Among 708 hypothyroid women 638 had live births. Postpartum hemorrhage was the most frequent maternal outcome (38.8%). The emergency cesarean section occurred in 23.4% of cases. We determined TSH levels in 53.2, 56.7, 61.7 and 66.6% of cases in preconception, 1st, 2nd, and 3rd trimester periods. A significant association existed between cesarean section and preconception thyrotropin levels \u3e 2.5 mIU/L, whereas postpartum hemorrhage was significantly associated with thyrotropin levels \u3e 2.5 mIU/L in the preconception and third trimester.Conclusion: Successful live births in our patients were complicated by maternal postpartum hemorrhage and a frequent number of emergency cesarean section
